A 60-year-old man is admitted to the coronary care unit with a large anterior wall myocardial infarction. On his second hospital day he begins to complain of the sudden onset of numbness in his right foot and an inability to move his right foot. On physical examination, the right femoral, popliteal, and pedal pulses are no longer palpable. Vascular consultation is obtained. Diagnosis of acute arterial embolus is made. Which of the following statements concerning this condition is true?
Appropriate management would be embolectomy of the right femoral artery under general anesthesia
Noninvasive hemodynamic testing is required
Prophylactic exploration of the contralateral femoral artery should be done despite the presence of a normal pulse
The source of the embolus is most likely the left ventricle
3d

The heart is the most common source of arterial emboli and accounts for 90% of cases. Within the heart, sources include diseased valves, endocarditis, the left atrium in patients with unstable atrial arrhythmias, and mural thrombus on the wall of the left ventricle in patients with a myocardial infarction. The diagnosis in this patient is clear, and therefore neither noninvasive testing nor arteriography is indicated. Arteriography in fact may also prove to be too stressful for a patient undergoing an acute myocardial infarction. Embolectomy of the femoral artery can be performed under local anesthesia with minimal risk to the patient. Emboli typically lodge in one femoral artery; contralateral exploration is not indicated in the absence of signs or symptoms. One should always prepare the contralateral groin in case flow is not restored via simple thrombectomy and femoral-femoral bypass is needed to provide inflow to the affected limb.

A 12-year-old boy has a cough and earache for the past 2 days. He has a history of recurrent infections, including otitis media, diarrhea, and pneumonia. Physical examination shows an erythematous right tympanic membrane, a cleft palate, and murmur suggestive of congenital heart disease. A thoracic CT scan shows a small thymus. Results of laboratory studies suggest mild hypoparathyroidism. Which of the following diagnostic studies is most likely to be helpful in diagnosing this patient's condition?

DiGeorge syndrome is an immunodeficiency characterized by infection, a small thymus, congenital malformations, and hypoparathyroidism. This cluster is characteristic of the 22q11.2 deletion syndrome, readily diagnosed by FISH. Adenosine deaminase deficiency can cause immunodeficiency, but it is not associated with congenital malformations. Branched DNA assay can detect HIV infection that can lead to AIDS, but no congenital anomalies are associated with this condition. A lymph node biopsy may show a reduction in T cells or B cells associated with various forms of immunodeficiency, but this is not a specific test that can aid in confirming a specific diagnosis. Trinucleotide repeats of the X chromosome, detected by PCR, are seen in fragile X syndrome, which manifests with mental retardation in males.

Hypoventilation always causes both hypoxemia and hypercapnia. If the hypoventilation syndrome is caused exclusively by impaired respiratory drive (e.g., drug overdose), then the alveolar-arterial PaO2 gradient remains normal. Often, hypoventilation results from more than one disorder in the respiratory system (e.g., COPD plus metabolic alkalosis secondary to diuretics and glucocorticoids).

Based on the above clinical scenerio,the diagnosis is Severe combined immunodeficiency. Severe combined immunodeficiency (SCID), is a genetic disorder in which both "arms" (B cells and T cells) of the adaptive immune system are impaired due to a defect in one of several possible genes Types of SCID X-linked severe combined immunodeficiency Purine nucleoside phosphorylase deficiency Adenosine deaminase deficiency Omenn syndrome Bare lymphocyte syndrome JAK3 Aemis/DCLRE1C X-linked severe combined immunodeficiency Most cases of SCID are due to mutations in the gene encoding the common gamma chain (gc), a protein that is shared by the receptors for interleukins These interleukins and their receptors are involved in the development and differentiation of T and B cells. The common gamma chain is encoded by the gene IL-2 receptor gamma, or IL-2Rg, which is located on the X-chromosome. For this reason, immunodeficiency caused by mutations in IL-2Rg is known as X-linked severe combined immunodeficiency. The condition is inherited in an X-linked recessive pattern. Adenosine deaminase deficiency: The second most common form of SCID after X-SCID is caused by a defective enzyme, adenosine deaminase (ADA), necessary for the breakdown of purines. Lack of ADA causes accumulation of dATP. The effectiveness of the immune system depends upon lymphocyte proliferation and hence dNTP synthesis. Without functional ribonucleotide reductase, lymphocyte proliferation is inhibited and the immune system is compromised. Purine nucleoside phosphorylase deficiency An autosomal recessive disorder involving mutations of the purine nucleoside phosphorylase (PNP) gene. PNP is a key enzyme in the purine salvage pathway. Impairment of this enzyme causes elevated dGTP levels resulting in T-cell toxicity and deficiency. Symptoms and diagnosis of SCID: Children with SCID are at risk for life-threatening infections. From their first months of life, they have infections that may be frequent, severe, long-lasting or hard to treat. Infections may occur in the lungs (pneumonia), around the brain and spinal cord (meningitis) or in the blood stream. The delay in detection is because newborns carry their mothers antibodies for the first few weeks of life and SCID babies look normal. treatment for SCID: bone marrow transplantation, Transduction of the missing gene to hematopoietic stem cells using viral vectors is being tested in ADA SCID and X-linked SCID gene therapy Reference: Harpers illustrated biochemistry 30th edition

Ans. (a) Chlamydia. Ref 1 = Diagnosis and management The diagnosis is chlamydia infection. It is very often asymptomatic but can have serious consequences of pelvic pain and fertility problems if untreated. It is more common in women who have a cervical ectropion. The presence of mucopurulent discharge should alert the clinician to the possibility of chlamydia. Diagnosis is confirmed by taking an endocervical swab. Treatment is with antibiotics, either azithromycin 1g immediately or doxycycline 100mg twice daily for seven days. Any sexual contacts need to be traced and treated. Possible different diagnoses Gonorrhoea. Cervical ectropion. Trichomonas. Differential diagnosis Gonorrhoea Occasionally presents with skin lesions. May cause pelvic inflammatory disease. Treatment is with antibiotics. Ref-2. teachmeobgyn.com/sexual-health/sexually-transmitted-infections/chlamydia/ Chlamydia is a sexually transmitted infection caused by the bacterium Chlamydia trachomatis. It is the most common bacterial STI reported in the UK - Public Health England reported 200,288 cases in 2015 (46% of all STI diagnoses). In this article we shall cover the pathophysiology and clinical features of a chlamydial infection, common investigations and its management. Pathophysiology C. trachomatis is an obligate intracellular gram negative bacterium of which there are different serotypes: Serotypes A-C - cause ocular infection. Serotypes D-K - responsible for classical genitourinary infection. Serotypes L1-L3 - cause lymphogranuloma venereum (LGV), an emerging infection in men who have sex with men, often resulting in proctitis. Transmission is via unprotected vaginal, anal or oral sex. However, penetration is not always necessary - and the infection can be spread via direct skin-to-skin contact of the genitals. If infected semen/vaginal fluid enters the eye it can cause chlamydial conjunctivitis, and it is also possible for an infected mother to pass on the infection to her baby during delivery. C. trachomatis enters the host cell as an elementary body (infectious form). Once inside the cell it becomes a reticular body, the non-infectious form capable of replication. Following replication, these reticular bodies mature back to elementary bodies, and following cell rupture the elementary bodies infect other cells resulting in inflammation and tissue damage. By TeachMeSeries Ltd (2018) Fig 1 - The replication cycle of chlamydia Risk Factors The following are risk factors associated with Chlamydia, most of which are common to other sexually transmitted infections: Age <25 Sexual partner positive for chlamydia Recent change in sexual partner Co-infection with another STI Non-barrier contraception or lack of consistent use of barrier contraception Clinical Features Chlamydia is often asymptomatic, with 50% of men and 70% of women unaware that they are infected. The incubation period is typically between 7 and 21 days, after which people may become symptomatic. In addition to the genitourinary features below, chlamydia can also infect the conjunctiva of the eye leading to irritation (chlamydial conjunctivitis), the rectum (discomfort and discharge) and the pharynx (often no symptoms). Women CC BY-SA 3.0, Fig 2 - Cervicitis and mucopurulent endocervical discharge in female chlamydial infection. Symptoms Dysuria Abnormal vaginal discharge Intermenstrual or postcoital bleeding Deep dyspareunia Lower abdominal pain Signs Cervicitis +/- contact bleeding Mucopurulent endocervical discharge Pelvic tenderness Cervical excitation Men Symptoms Urethritis Dysuria Urethral discharge Epididymo-orchitis Testicular pain Signs Epididymal tenderness Mucopurulent discharge Differential Diagnoses A full STI screen should be undertaken for a patient presenting with chlamydia due to the common presenting symptoms of various STIs. In particular, it is difficult to clinically differentiate between gonorrhoea and chlamydia so many NAATs now offer dual testing for both diseases. Treatment for gonorrhoea covers both N. gonorrhoeae and C. trachomatis. Investigations Chlamydia tests are available from sexual health clinics, GUM clinics and GP surgeries. There is also a National Chlamydia Screening Programme in England for people aged under 25 and this testing is often available from pharmacies, universities and contraception clinics. Chlamydia is too small to be seen via microscopy so a nucleic acid amplification test (NAAT) is the recommended investigation to diagnose genital chlamydia from specimens taken at examination or by the patient: Women: Vulvo-vaginal swab (first choice), endocervical swab or first catch urine sample. Men: first catch urine sample (first choice) or urethral swab. If indicated, swabs may also need to be taken from the rectum, eye(s) and throat. If positive for chlamydia, contact tracing is necessary so that the patient's current sexual partner(s) and recent partners can be tested and treated. Patients are recommended to have a full STI screen due to the possibility of co-infection and the similar nature of signs and symptoms. Management Antibiotic treatment is recommended for uncomplicated urogenital chlamydial infection: Doxycycline 100mg twice daily for 7 days or Azithromycin 1g single dose Alternative treatment when doxycycline and azithromycin are contraindicated: Erythromycin 500mg twice daily for 10- 14days Ofloxacin 200mg bd or 400mg od for seven days Patients are advised to avoid sexual intercourse and oral sex until they and/or their partner have completed treatment (or 7 days following azithromycin). Test of cure is not usually required unless the patient is pregnant, compliance was poor or when symptoms persist. If aged <25, repeat testing is recommended 3 months after treatment. Complications In women, ascending infection can lead to salpingitis and/or endometritis which can result in pelvic inflammatory disease (PID). PID can lead to perihepatitis, ectopic pregnancy and may ultimately result in infertility. In men, the infection can spread to cause epididymitis or epididymo-orchitis causing the testes to become painful and swollen. If left untreated, it is thought that this can affect fertility. Chlamydia can also result in sexually acquired reactive arthritis where the joints/eyes/urethra become inflamed and this is more common in men. Chlamydia in Pregnancy Chlamydia may increase the risk of premature delivery with low birth weight and it is thought the infection might increase the chance of miscarriage or stillbirth. Chlamydia in pregnancy is treated with antibiotics, however doxycycline and ofloxacin are contraindicated so azithromycin and erythromycin are the drugs of choice. If a baby contracts chlamydia they may present with inflammation and discharge in their eyes, indicative of neonatal chlamydial conjunctivitis (5-12 days after birth) and it is also possible for them to develop pneumonia (1-3 months after birth). If suspected, swabs can be taken from the eyelid or nasopharynx as indicated. Neonates are treated with oral erythromycin. Full details for the management for Chlamydia during pregnancy and for the neonate can be found in the UK national guidelines.

A 62 year old woman Vasanti, has a 3 month history of increasing right shoulder pain. She is now unable to lift her arm to brush her hair or to take a can off a shelf. She denies any numbness or tingling or radiation of the pain down her arm. On physical examination, she exhibits weakness in abduction and external rotation or her right arm. Her shoulder shows a normal passive range of motion. When asked to hold her arms abducted to 90 degrees, she is unable to do so on the right. There is no motor weakness in her forearm or hand. Her right upper extremity has normal pulses and normal sensation. Which of the following muscles make up the injured structure?
Supraspinatus, infraspinatus, teres major, deltoid
Supraspinatus, infraspinatus, teres major, subscapularis
Supraspinatus, infraspinatus, teres minor, deltoid
Supraspinatus, infraspinatus, teres minor, subscapularis

The above history describes a rotator cuff tear. Patients classically have difficulty doing overhead activities. On physical examination, she has weakness with abduction and external rotation of her shoulder. The supraspinatus is responsible for abduction and the infraspinatus is responsible for external rotation of the shoulder. These muscles, along with the teres minor and subscapularis, make up the rotator cuff. Brachial plexus injuries commonly present with some type of numbness or tingling in the upper extremity. Glenohumeral ahritis is unlikely because she has a full passive range of motion, and shoulder ahritis is commonly associated with a decreased range of motion. Also this history is relatively sho term. Proximal humerus fracture and shoulder dislocation are unlikely because this process has been present for 3 months. These injuries need more acute treatment. Also she has a full passive range of motion, which is not common with fractures or dislocations. Ref: McMahon P.J., Kaplan L.D. (2006). Chapter 4. Spos Medicine. In H.B.

A 45-year-old woman is admitted to the hospital with a swelling on the side of her face of 2 months' duration. Radiographic examination reveals a parotid gland tumor. An operative procedure is performed in which the tumor is removed from the parotid gland. Three months postoperatively the patient complains that her face sweats profusely when she tastes or smells food, and a diagnosis is made of Frey syndrome (gustatory sweating). Which of the following nerves was most likely injured during the procedure?
Buccal
Inferior alveolar
Auriculotemporal
Facial
2c
single
Frey syndrome occurs following damage to parasympathetic axons in the auriculotemporal nerve. When these postganglionic cholinergic axons grow peripherally after parotid surgery, they establish synapses upon the cholinergic sweat glands, which are innervated normally only by sympathetic fibers. As the peripheral nerves make new connections, aberrant connections can be formed between the auriculotemporal nerve and other glands (not usually innervated by the auriculotemporal nerve). This results in flushing and sweating in response to the thought, smell, or taste of food, instead of the previous, normal salivary secretion by the parotid gland.

A 33-year-old previously healthy man with persistent fever and heart murmur is diagnosed with infective endocarditis. He receives a high dosage of a cephalosporin antibiotic during the next 10 days. He now has increasing fatigue. On physical examination, he has tachycardia and scleral icterus. Laboratory studies show a hemoglobin level of 7.5 g/dL, platelet count of 261,000/ mm3, and total WBC count of 8300/ mm3. The direct Coombs test is positive. The peripheral blood smear shows reticulocytosis. Which of the following is the most likely cause of his anemia?
Dietary nutrient deficiency
Disseminated intravascular coagulopathy
Immune-mediated hemolysis
Infection with parvovirus
2c
single
Drug-induced hemolytic anemias are neither common nor severe enough to be recognized since the hemolysis is mainly extravascular. However, many patients receive drugs, so the potential for a drug reaction exists, and this immune-mediated mechanism must be distinguished from other causes for anemia. Cephalosporins are the most frequent drugs implicated. Treatment consists of cessation of therapy with the drug because most cases are due to drug-dependent antibody formation. Nutrient deficiencies reduce marrow production, so reticulocytosis is unlikely. DIC is unlikely with a normal platelet count. Parvovirus infection may suppress erythropoiesis transiently in individuals with normal red cells but may precipitate an aplastic crisis in those with a hemoglobinopathy. Persons with abnormal red cells are likely to have a history of anemia. Hemoglobinopathies are not Coombs positive.

Laboratory findings show the serum creatinine level is 5.8 mg/dL. C3 nephritic factor is present in serum, resulting in hypocomplementemia, and the ANA test result is negative. Urinalysis shows 2+ blood and 1+ protein. A renal biopsy is done; microscopic examination shows hypercellular glomeruli and prominent ribbonlike deposits along the lamina densa of the glomerular basement membrane. Which of the following forms of glomerulonephritis is most likely to be present in this patient?
Chronic glomerulonephritis
Dense deposit disease
Membranous nephropathy
Postinfectious glomerulonephritis
1b
single
Dense deposit disease (formerly membranoproliferative glomerulonephritis type II) usually leads to hematuria, and half of the cases end in chronic renal failure. The term chronic glomerulonephritis (GN) often is used when sclerosis of many glomeruli is present with no clear cause. Membranous nephropathy is often accompanied by proteinuria but less likely hematuria and is characterized by thickening of only the basement membrane and small electron-dense deposits. Postinfectious GN is often characterized by a hypercellular glomerulus with infiltration of polymorphonuclear leukocytes, but no basement membrane thickening. A rapidly progressive GN is marked by crescents forming in the Bowman space.

This patient is morbidly obese. The extra weight puts a strain on joints, particularly the knees, increasing the risk for osteoarthritis. Although the overall risk of cancer increases with obesity, the relationship between endometrial carcinoma and obesity is well established. About 80% of individuals with type 2 diabetes mellitus are obese. The relationship between diet and obesity to colon cancer is not as well established. Worldwide, most hepatocellular carcinomas arise in individuals infected with hepatitis B; chronic alcoholism also is a risk factor. Pulmonary adenocarcinoma is the least likely bronchogenic cancer to be associated with smoking. Some renal cell carcinomas are associated with smoking.

He is hemodynamically unchanged and his chest x-ray (CXR) is also unchanged. The most likely cause of his worsening respiratory acidosis in the prone position is
Pneumothorax
Increased dead space

2c
multi
The prone positioning reduces the disparity in mechanics between the dependent and nondependent regions of the lungs. This reduces the collapsing of the alveoli in the dependent portions of the lungs and overdistention in the nondependent portions of the lungs. The prone position also has other effects - it allows a more normal curvature of the diaphragm and allows better function. It also stiffens the chest wall allowing a more even distribution of ventilation and reduction in overventilation of nondependent alveoli

Answer: (d) As the ureter crosses the external iliac artery at the pelvic brim and as the ureter passes through the wall of the bladder.* Renal and ureteric calculi generally are formed in the kidneys and then lodge at one of three locations:o at the junction of the renal pelvis with the ureter;o as the ureters cross the external iliac vessels at the pelvic brim;o as the ureters pass through the wall of the bladder.* Calculi occasionally form in the minor or major calyces or in the renal pelves and infundibula, but those so called "staghorn"calculi, would produce mid-back pain.* Renal calculi rarely become stuck as the ureter crosses the edge of the false pelvis.* The ureter does not pass through the center of the trigone, but rather opens at the superior lateral edge of the trigone.* The referred pain from ureteric calculi is usually described as from "loin to groin" in that it often starts in the mid back then over the kidney and extends in a band toward the labia majora or scrotum (from T11-L2).* Normally the pain is intermittent and comes and goes in waves and may change in location, generally moving interiorly.* Since the ureters undergo peristaltic movement, the calculi often move with time.

However, the fact that he is young, otherwise healthy, and has avoided solid foods all his life suggests he has a congenital problem. He does not describe symptoms of biliary colic nor does he have signs of cancer. Episodic pain is not typical during bouts of acute pancreatitis, and pancreas divisum does not cause duodenal obstruction.

Magnesium deficiency is common in malnourished patients and patients with large gastrointestinal fluid losses. The neuromuscular effects resemble those of calcium deficiency-namely, paresthesia, hyperreflexia, muscle spasm, and ultimately tetany. The cardiac effects are more like those of hypercalcemia. An electrocardiogram therefore provides a rapid means of differentiating between hypocalcemia and hypomagnesemia. Hypomagnesemia also causes potassium wasting by the kidney. Many hospital patients with refractory hypocalcemia will be found to be magnesium deficient. Often this deficiency becomes manifest during the response to parenteral nutrition when normal cellular ionic gradients are restored. A normal blood pH and arterial PCO2 rule out hyperventilation. The serum calcium in this patient is normal when adjusted for the low albumin. Hypomagnesemia causes functional hypoparathyroidism, which can lower serum calcium and thus result in a combined defect.

The multiple marker screening test, also referred to as the expanded AFP test or triple screen, consists of maternal serum measurements of estriol, human chorionic gonadotropin, and a-fetoprotein. The multiple marker screening test is used to determine a pregnant patient's risk of having a baby with an- euploidy and a neural tube defect. The AFP test has the greatest sensitivity when done between 16 and 18 weeks. A maternal serum AFP level that is greater than or equal to 2.0 to 2.5 MOM indicates an elevated risk for a neural tube defect and indicates that further workup and evaluation are needed. The first step when an elevated serum AFP result is obtained is to have the patient undergo an ultrasound to verify that the gestational age of the pregnancy is correct. The sonogram can also identify a fetal death in utero, multiple gestation, or a neural tube or abdominal defect, which could all explain the elevated AFP level. A repeat serum AFP test can be done, because at a level of 2.0 MOM there is some overlap between normal and affected pregnancies. The repeat test should be done as soon as possible; waiting until 20 weeks decreases the sensitivity of the test and wastes valuable time in the workup. An amniocentesis is recommended if a neural tube defect is suspected, in order to measure amniotic fluid levels of AFP and therefore confirm the findings of the maternal serum AFP. The physician would not immediately refer the patient for a chorionic villus sampling because this procedure obtains placental tissue for fetal karyotyping and does not add to information regarding the presence of a neural tube defect. A cordocentesis or percutaneous umbilical cord blood sampling (PUBS) is a procedure whereby the umbilical vein is punctured under ultrasonic guidance and a fetal blood sample is obtained. Usually a PUBS is performed when rapid fetal karyotyping must be done, such as in a situation where severe growth restriction exists. PUBS is most commonly used in situations where fetal hydrops exists to obtain information regarding fetal platelet counts and fetal hematocrits.

Two weeks after a viral syndrome, a 2-year-old child develops bruising and generalized petechiae, more prominent over the legs. No hepatosplenomegaly or lymph node enlargement is noted. The examination is otherwise unremarkable. Laboratory testing shows the patient to have a normal hemoglobin, hematocrit, and white blood cell (WBC) count and differential. The platelet count is 15,000/mL. Which of the following is the most likely diagnosis?
Von Willebrand disease (vWD)
Acute leukemia
Idiopathic (immune) thrombocytopenic purpura (ITP)
Aplastic anemia

In children, ITP is the most common form of thrombocytopenic purpura. In most cases, a preceding viral infection can be noted. No diagnostic test identifies this disease; exclusion of the other diseases listed in the question is necessary. In this disease, the platelet count is frequently less than 20,000/mL, but other laboratory tests yield essentially normal results, including the bone marrow aspiration (if done). Complications are uncommon; significant bleeding occurs in only 5% of cases and intracranial hemorrhage is even rarer. The treatment of childhood ITP is controversial. Patients with mild symptoms such as bruising and self-limited epistaxis may be observed, while patients with significant bleeding should be treated. IVIG and corticosteroids are effective in causing a rapid increase in platelet count, but controversy exists surrounding the use of prednisone before ruling out leukemia with a bone marrow aspirate. For Rh-positive patients with a working spleen, the use of anti-D immunoglobulin also results in an increase in platelet count. For patients with chronic (> 1 year) ITP, a splenectomy may be necessary.Aplastic anemia is unlikely if the other cell lines are normal. vWD might be expected to present with bleeding and not just bruising. It is unlikely that acute leukemia would present with thrombocytopenia only. Thrombotic thrombocytopenic purpura is rare in children.

He has left-sided heart failure with pulmonary edema and congestion. His reduced cardiac output leads to diminished renal blood flow that stimulates the renin-angiotensin mechanism to retain salt and water to increase plasma volume. He has prerenal azotemia with a high BUN-to-creatinine ratio and low fractional excretion of sodium. The other options do not explain his pulmonary edema. An aldosterone- secreting adrenal adenoma (Conn syndrome) would increase aldosterone, but decrease the plasma renin. In chronic adrenal failure (Addison disease), there should be hyperkalemia and hypoglycemia accompanying hyponatremia. Chronic glomerulonephritis with chronic renal failure would be associated with a BUN-to-creatinine ratio around 10:1. Pulmonary fibrosis would lead to cor pulmonale and a prominent right heart border with features of right-sided congestive heart failure. The syndrome of inappropriate antidiuretic hormone (ADH) is a paraneoplastic syndrome that can occur with pulmonary small cell carcinomas, and secretion of antidiuretic hormone (SIADH) would increase ADH and cause more severe hyponatremia, but would not have a major effect on the renin-angiotensin mechanism, and sodium excretion would be higher.

Pain suppression ("Analgesia") system in the Brain and Spinal Cord: It consists of three major components: The periaqueductal gray (in midbrain) and periventricular areas of the mesencephalon and upper pons surround the aqueduct of sylvius and poions of the third and fouh ventricles. Neurons from these areas send signals to The raphe magnus nucleus, a thin midline nucleus reticularis paragigantocellularis, located laterally in the medulla. From these nuclei, second order signals are transmitted down the dorsolateral columns in the spinal cord to A pain inhibitory complex located in the dorsal horns of the spinal cord. At this point, the analgesia signals can block the pain before it is relayed to the brain. Note: "Several transmitter substances are involved in the analgesia system (of brain and spinal cord); especially involved are enkephalin and serotonin" . "Along with the opioid receptor, the component nuclei of this pain modulating circuit contain endogenous opioid peptides such as the enkephalins and B-endorphin". About a dozen such opiate-like substances have now been found at different point of the nervous system ; all are breakdown products of three large protein molecules ; pro-opiomelanocoin, proenkephalin, and prodynorphin. Among the major impoant of these opiate-like substances are B-endorphin, met-enkephalin, leu-enkephalin, and dynorphin. Fibers originating in this area send signal to the dorsal horns of the spinal cord to secrete serotonin at their endings. The serotonin cause local cord neurons to secret enkephalin as well. The enkephalin is believe to cause both presynaptic and postsynaptic inhibition of incoming type C and type A/ pain fibers where they synapse in the dorsal horns. The powerful effect of expectation and other psychological variables on the perceived intensity of pain implies the existence of brain circuits that can modulate the activity of the pain transmission pathways. One of these circuits has link in the hypothalamus, midbrain, and medulla, and it selectively controls spinal pain-transmission neurons through a descending pathway.

Echocardiography is an invaluable tool for assessing cardiovascular function in both normal and disease states. In the case of atrial fibrillation (AF), a chronic course versus an acute and self-limited course poend completely different treatment strategies and long-term prognoses. The most common cause of chronic AF is valvular disease, followed by congestive hea failure (CHF). The most common anatomic correlate seen in patients with AF (Framingham Hea Study) is an enlarged left atrium. A dilated left ventricle is commonly seen with both CHF and AF. However, an enlarged left atrium is more closely correlated with chronic AF than is left ventricular dilation. The causal relationship between an enlarged left atrium and AF is unclear. A dilated right ventricle is commonly seen in severe right hea failure (RHF). The most common cause of RHF is left hea failure (LHF). There is no consistent relationship between right hea size and the presence of AF. A hyperophied ventricular septum is commonly seen in hypeensive hea disease or idiopathic hyperophic aoic stenosis. Chronic AF in these patients, however, is much less common. Ref: Prystowsky E.N., Padanilam B.J., Waldo A.L. (2011). Chapter 40. Atrial Fibrillation, Atrial Flutter, and Atrial Tachycardia. In V.

Careful physical examination can be very useful in diagnosing many common pulmonary disorders. Atelectasis and large pleural effusions both can present with decreased fremitus, dullness or flatness to percussion, and absent breath sounds. In atelectasis, tracheal shift, if present, is toward the affected side, and the opposite for a large pleural effusion. Asthma's most typical manifestations are prolonged expiration and diffuse wheezing. However, impaired expansion, decreased fremitus, hyperresonance, and low diaphragms can also be found. A complete pneumothorax results in absent fremitus, hyperresonance or tympany, and absent breath sounds. Lobar pneumonia is characterized by consolidation with increased fremitus, dullness, and auscultatory findings of bronchial breathing, bronchophony, pectoriloquy, and crackles.

The patient has a classical case of Lesch-Nyhan syndrome, an X-linked disorder due to severe deficiency of the purine salvage enzyme hypoxanthine-guanine phosphoribosyl transferase (HP). This defect is associated with excessive de novo purine synthesis, hyperuricemia, and the clinical signs and symptoms described in the question stem. The biochemical basis of the often striking self-mutilatory behavior (which may require restraints and even tooth extraction) has never been established. Treatment with allopurinol inhibits xanthine oxidase and reduces gouty ahritis, urate stone formation, and urate nephropathy. It does not, however, modify the neurologic/psychiatric presentation.

multi
Hyperosmolar-nonketotic coma is a serious complication seen when an excessive amount of glucose is given, especially in the presence of sepsis, steroids, or inadequate insulin. Furthermore, the combination of surgery and sepsis results in an increased insulin- resistant state. The increased urine output is secondary to osmolar load from blood glucose. Low CVP, hypernatremia, and BUN-to- creatinine ratio over 20 suggest hypovolemia and not fluid overload. Normal creatinine level and BUN-to-creatinine ratio over 20 rules out high-output renal failure. The stress of surgery is characterized by water retention and not diuresis. Management consists of aggressive hydration, discontinuation of TPN, and insulin drip. Insulin drives the potassium intracellularly and potassium must be replaced.

This man has a complication of viral influenza; a secondary bacterial pneumonia has developed. This usually occurs 2-3 days after the initial viral symptoms resolve. Primary viral pneumonia with influenza is not common. Spneumoniae, Staphylococcus, and H influenzae are the most common bacterial invaders in pulmonary complications of influenza. Pneumonia is the leading cause of death and may also be due to Spneumoniae and H influenzae. Mixed viral and bacterial pneumonia is common; pure viral pneumonia in influenza is uncommon (but can be very severe).

Intravascular hemolysis from blood transfusion is usually due to ABO incompatibility, often from human error. Symptoms of intravascular hemolysis include flushing, pain at the infusion site, chest or back pain, restlessness, anxiety, nausea, and diarrhea. Signs include fever and chills, shock, and renal failure. In comatose patients, hemoglobinuria or bleeding from disseminated intravascular coagulation can be the first sign. Management is supportive. Acute hemolysis can also result from antibodies directed against other RBC antigens such as Rh, Kell, or Duffy.

Many diseases involve hematuria, and a few of these diseases occur in the setting of an upper respiratory infection or of upper respiratory signs and symptoms. When hematuria follows within 2 days of the onset of an upper respiratory infection without skin lesions in a young patient, IgA nephropathy (Berger's disease) should be considered. This disease involves the deposition of IgA in the mesangium of the glomeruli. Light microscopic examination may suggest the disease, but renal biopsy immunofluorescence (IF) must be performed to confirm it. This disorder may be the most common cause of nephritic syndrome worldwide. The hematuria may become recurrent, with proteinuria that may approach nephrotic syndrome propoions. Serum levels of IgA may be elevated. A small percentage of patients may progress to renal failure over a period of years. In contrast to Berger's disease, a linear IF pattern suggests a type II hypersensitivity reaction, such as Goodpasture's disease, while a granular pattern is seen with poststreptococcal glomerulonephritis (GN), membranous GN, focal segmental glomerulosclerosis, and membranoproliferative GN. Most positive immunofluorescence patterns involve IgG and C3, except that a granular IgM pattern is present in focal segmental glomerulosclerosis, while mesangial IgA is seen in IgA nephropathy (Berger's disease). Lipoid nephrosis would have a negative IF pattern; that is, there would be no staining present. Reference: Robbins & Cotran Pathologic Basis of Disease, 9edition

Anti-neutrophil cytoplasmic autoantibody (ANCA)- associated vasculitis (granulomatosis with polyangiitis) is a form of hypersensitivity reaction to an unknown antigen characterized by necrotizing granulomatous inflammation that typically involves small to medium-sized vessels, although many organ sites may be affected. Pulmonary and renal involvement can be life-threatening. C-ANCAs (antibodies mainly directed against neutrophil proteinase 3) are found in more than 90% of cases. Fibromuscular dysplasia is a hyperplastic medial disorder, usually involving renal and carotid arteries; on angiography, it appears as a "string of beads" caused by thickened fibromuscular ridges adjacent to less involved areas of the arterial wall. Granuloma pyogenicum is an inflammatory response that can produce a nodular mass, often on the gingiva or the skin. Kaposi sarcoma can produce plaque-like to nodular masses that are composed of irregular vascular spaces lined by atypical-appearing endothelial cells; skin involvement is most common, but visceral organ involvement can occur. Polyarteritis nodosa most often involves small muscular arteries, and sometimes veins. It causes necrosis and microaneurysm formation followed by scarring and vascular occlusion, mainly in the kidney, gastrointestinal tract, and skin of young to middle-aged adults. Takayasu arteritis is seen mainly in children and involves the aorta (particularly the arch) and branches such as the coronary and renal arteries, with granulomatous inflammation, aneurysm formation, and dissection.

Myelofibrosis with myeloid metaplasia is a myeloproliferative disorder that is also a stem cell disorder in which neoplastic megakaryocytes secrete fibrogenic factors leading to marrow fibrosis. The neoplastic clone then shifts to the spleen, where it shows trilineage hematopoietic proliferation (extramedullary hematopoiesis), in which megakaryocytes are prominent. The marrow fibrosis and the extramedullary hematopoiesis in the spleen fail to regulate orderly release of leukocytes into the blood. The peripheral blood has immature RBC and WBC precursors (leukoerythroblastic picture). Hematopoietic cell proliferation and turnover increases purine metabolism and uric acid production. Teardrop RBCs are misshapen RBCs that are seen when marrow undergoes fibrosis. Marrow injury also can be the result of other causes (e.g., metastatic tumors, irradiation). These causes also can give rise to a leukoerythroblastic picture, but splenic enlargement with trilineage proliferation usually is not seen. The other causes mentioned - Hodgkin lymphoma, portal hypertension, and Histoplasma capsulatum infection - can cause splenic enlargement, but not marrow fibrosis. Metastases to the spleen are uncommon.

Discussing options one by one: a. Iron deficiency anemia: So severe anemia & expansion of erythroid marrow are usually not seen b. Acute lymphoid Leukemia: Low MCV, no obvious involvement of other cell lines, and expansion of erythroid marrow are incompatible with diagnosis of ALL c. Hemoglobin D disease: Low MCV and MCH with target cells suggest abnormality of haemoglobin like HbD disease d. Hereditary spherocytosis: Normal osmotic fragility goes against hereditary spherocytosis

Lymphocytes positive for CD 19, CD20, CD23, CD5 suggest the diagnosis of chronic lymphocytic leukemia/small lymphocytic lymphoma. In CLL/SLL larger lymphocytes show high mitotic activity and form proliferation centre. Chronic lymphocytic leukemia (CLL), small lymphocytic lymphoma (SLL). CLL and SLL are identical neoplasm/arise due to an abnormal neoplastic proliferation of B cells. CLL involves primarily bone marrow and blood, while SLL involves lymph nodes Morphology of CLL/SLL The tumor cells of CLL are small B lymphocytes. Leukemic cells have the morphological appearance of normal small to medium sized lymphocytes with clumped chromatin, inconspicuous nuclei and a small ring of cytoplasm. The lymph node architecture is diffusely effaced by these tumor cells. These cells are mixed with variable numbers of larger cells called prolymphocytes. In many cases, prolymphyocytes gather together focally to form as proliferation centers, so called because they contain relatively large number of mitotic activity. When present proliferation centers are pathognomonic for CLL/SLL. In CLL, the peripheral blood contains increased numbers of small, round lymphocytes with scant frequently disrupted in the process of making smears, producing So called smudge cells.. Markers of CLL tumor cells CLL is a tumor of mature -cells, therefore it expresses the B-cell markers such as CD19, CD20 and surface IgM and IgD. In addition CD23 and CD5 are also present (In contrast to mantle cell lymphoma which is positive for CD5 but negative for CD23).

Ans. CExplanation:* Aliskiren is a renin inhibitor. It does not inhibit secretion of renin. Rather it inhibits the action of renin after it is secreted. Beta blockers act by inhibiting the secretion of renin.* ACE inhibitors like enalapril prevent the degradation of bradykinin. Excessive bradykinin can result in cough and angioedema as adverse effects.* Losartan is an angiotensin receptor antagonist. It does not inhibit the formation of angiotensin II.* Epleronone is a new aldosterone antagonist like spironolactone, however unlike spironolactone, it does not cause gynaecomastia.* Sampatrilat and omapatrilat are vasopeptidase inhibitors. These can inhibit two enzymes; ACE and neprilysin.

The PA view shows a large, well-defined opacity in the right hilum. The ascending aoa shadow is not silhouetted, suggesting that this is a posterior opacity. The left hilum and the left PA appear normal. This large posterior mediastinal mass is an esophageal lesion, and the presence of steady, constant, boring pain is indicative of mediastinal involvement and therefore inoperability. Cough may be due to aspiration or laryngeal reflux; clubbing can at times be seen in both benign and malignant lesions of the esophagus and does not indicate mediastinal involvement or inoperability

This is a classic example of an infection with herpes simplex virus (probably type 2). This agent causes lytic infections in mucoepithelial cells. It is then retrogradely transpoed into neurons of the sacral ganglia, where it lays dormant during the asymptomatic phase of the disease. Fibroblasts may be infected by cytomegalovirus, another herpes virus, but this produces a distinctive mononucleosis-like syndrome in most normal individuals. Lymphocytes and macrophages may be infected by herpes simplex type 2 but are not the site of residence of the virus during quiescent periods. Ref: Brooks G.F. (2013). Chapter 33. Herpesviruses.

Tonicity and osmolarity are different. Osmolarity is merely another measure of solute concentration. Tonicity depends on the cell membrane and the solute and is determined by the behavior of the cells. The fact that red blood cells placed into the test solution gained volume (swelled) indicates that the test solution is hypotonic. In contrast, the osmolarity of the test solution cannot be determined by the behavior of the cells.

The powder is added in small increments. Mixing is done with stainless spatula using brisk circular motion. Each increment is mixed for 15 to 20 seconds. A large area is covered during mixing in order to dissipate the exothermic heat. Maximum amount of powder should be incorporated in the liquid to ensure minimum solubility and maximum strength.  Note: An appropriate consistency is attained by addition of more powder to the liquid and not by allowing a thin mix to thicken.

A 35-year-old man has had an outbreak of pruritic lesions over the extensor surfaces of the elbows and knees during the past month. He has a history of malabsorption that requires him to eat a special diet, but he has had no previous skin problems. On physical examination, the lesions are 0.4- to 0.7-cm vesicles. A 3-mm punch biopsy of one of the lesions over the elbow is performed and on microscopic examination shows the accumulation of neutrophils at the tips of dermal papillae and the formation of small blisters caused by separation at the dermo-epidermal junction. Immunofluorescence studies show granular deposits of IgA localized to tips of dermal papillae. Laboratory studies show serum antigliadin antibodies. What is the most likely diagnosis?
Bullous pemphigoid
Contact dermatitis
Dermatitis herpetiformis
Discoid lupus erythematosus
2c
multi
Dermatitis herpetiformis can accompany the celiac disease. The IgA or IgG antibodies formed against the gliadin protein in gluten that is ingested (commonly in wheat, rye, and barley grains) cross-react with reticulin. Reticulin is a component of the anchoring fibrils that attach the epidermal basement membrane to the superficial dermis. This explains the localization of the IgA to the tips of dermal papillae and the site of inflammation. A gluten-free diet may relieve the symptoms. Bullous pemphigoid can occur in older individuals, with an antibody directed at keratinocytes to produce flaccid bullae, but there is no association with celiac disease. Contact dermatitis is most likely to be seen on the hands and forearms. It is a type IV hypersensitivity reaction without immunoglobulin deposition and would not persist for 1 month. Discoid lupus erythematosus is seen in sun-exposed areas and has the appearance of an erythematous rash. Erythema multiforme is a hypersensitivity response to infections and drugs; it produces macules and papules with a red or vesicular center, but it is probably mediated by cytotoxic lymphocytes and not by immunoglobulin deposition. Pemphigus vulgaris is an autoimmune disease in which IgG deposited in acantholytic areas forms vesicles that rupture to form erosions; it is not related to celiac disease.

S. pneumoniae colonizes the nasopharynx of 5-10% of healthy adults and up to 20-40% of children. The source of pneumococcal meningitis is either direct extension from middle ear or sinus infections, or via seeding from a bacteremia.

An 8 year old boy is brought to the emergency room with a 3-day history of fever to 102 degrees F and abdominal pain. He also complains of pain in his right knee and right elbow. He was seen four weeks ago because of a sore throat and a rash. A throat culture performed at that time grew gram-positive cocci in chains. Amoxicillin was prescribed, but the boy's mother did not fill the prescription. On physical exam his temp is 101.7F, HR 96, and BP 100/60. Cardiac exam reveals a pansystolic blowing murmur heard best at the apex. His right elbow is tender on extension and flexion with mild swelling. Laboratory tests reveal a positive C-reactive protein, an ESR of 40 and a WBC of 22,000 with a left shift. ECG shows a prolonged PR interval. Which of the following tests would be positive for the microorganism responsible for this patient's illness?

This case is classic for Rheumatic fever, including two of the major Jones criteria (carditis, polyahritis) and several minor criteria (fever, ahralgia, elevated ESR, leukocytosis, C-reactive protein, prolonged PR interval). Rheumatic fever is a sequelae of untreated infection with Group A Streptococcus (S. pyogenes). S. pyogenes is differentiated from the other beta-hemolytic Strep by its sensitivity to the antibiotic bacitracin. The catalase test is used to differentiate Staphylococci from Streptococci. Staphylococci are catalase positive, Streptococci are catalase negative. So, S. pyogenes would be catalase negative. The coagulase test is used to differentiate Staph aureus from the other Staph spp. Staph aureus is coagulase positive; the others are negative. Sensitivity to novobiocin is used to differentiate Staph saprophyticus (resistant) from Staph epidermidis (sensitive). Ref: Levinson W. (2012). Chapter 66. Tolerance & Autoimmune Disease. In W.

The syndrome represented by the clinical vignette is infectious mononucleosis. Epstein-Barr virus (EBV) is the usual cause of heterophile-positive infectious mononucleosis; cytomegalovirus is responsible for a minority of cases. Rarely, splenic rupture requiring splenectomy can result from splenomegaly and capsular swelling, usually occurring during the 2nd and 3rd weeks of the illness. Acute cholecystitis is not associated with infectious mononucleosis. The most frequently isolated pathogens are E. coli, Klebsiella spp., group D Streptococcus, Staphylococcus spp., and Clostridium spp. Ascending cholangitis is not associated with infectious mononucleosis. Cholangitis usually presents with biliary colic, jaundice, and spiking fever with chills (Charcot's triad). Blood cultures are usually positive (E. coli is a common isolate), with an accompanying leukocytosis. AIDS-related cholangitis has been repoed, presenting with abdominal pain and obstructive liver symptoms. Potential etiologic agents include Cytomegalovirus, Cryptosporidium parvum, and Microsporidia, including Enterocytozoon cuniculi. Diarrhea is not usually produced by infectious mononucleosis.

A 31-year-old primigravid woman comes to the physician for a prenatal visit. She is known to be HIV positive. She also has asthma, for which she uses an inhaler. She had a diagnostic laparoscopy at age 20 for pelvic pain and has had no other surgeries. She has no known drug allergies. Extensive counseling is given to the patient regarding veical transmission of HIV to the fetus. It is recommended to her that she take antiretroviral therapy during the pregnancy to decrease the veical transmission rate. It is also recommended to her that she have a scheduled cesarean delivery. After consideration of these options, the patient chooses not to take the antiretrovirals and opts for a vaginal delivery.

Studies have demonstrated that in the absence of maternal treatment with antiretroviral therapy or scheduled cesarean delivery, the rate of veical transmission is approximately 25%. Thus, all pregnant women should be offered HIV testing to identify those patients who are infected so that they may receive antiretroviral therapy and be offered scheduled cesarean delivery to decrease the rate of veical transmission. 2% (choice A) represents the approximate rate of veical transmission in women who receive antiretroviral therapy during the pregnancy and a scheduled cesarean delivery (i.e., a cesarean delivery prior to the onset of labor or rupture of membranes.) 8% (choice B) represents the approximate rate of veical transmission when women are treated with antiretroviral therapy during pregnancy and the neonate is treated postpaum. This rate was identified in the landmark study from the Pediatric AIDS Clinical Trials Group 076 study. This study showed that antepaum, intrapaum, and postpaum zidovudine (ZDV) use would reduce the veical transmission rate from 25% to 8%.

Limited scleroderma (former CREST syndrome), a form of systemic sclerosis, does not progress to include serious pulmonary fibrosis or renal disease. Therefore she is less likely to have diffuse scleroderma, which is associated with the anti-DNA topoisomerase antibody. Antimicrosomal (anti-thyroid peroxidase) antibodies are seen in autoimmune thyroid diseases, such as Hashimoto thyroiditis and Graves' disease. Antimitochondrial antibody appears most frequently in primary biliary cirrhosis. ANCA can be a marker for various forms of vasculitis. Anti-transglutaminase antibodies are seen in celiac disease, which is marked by malabsorption, not esophageal dysmotility.

This chest x-ray shows a large, air-containing, hyperlucent opacity in the middle poion of the thorax representing a large hernia in the mediastinum. The lung parenchyma shows increased linear and reticular markings, predominantly in the lower zones, consistent with the diagnosis of interstitial disease. The symptoms described are due to an acid reflux disorder, and the chest x-ray shows a large hiatal hernia. Hiatal hernia represents herniation of the stomach through the esophageal hiatus and is frequently found in adults. It occurs as an oval retrocardiac mass, most often with an air-fluid level, and is due to laxity, stretching, and widening of the hiatus. Obesity and increased intraabdominal pressures are contributing factors. The majority of hernias spontaneously reduce and are called sliding hernias. A paraesophageal hernia occurs when the stomach herniates next to the distal esophagus. Patients may be asymptomatic or may have symptoms of reflux.

Wilson disease is an inherited disorder in which toxic levels of copper accumulate in tissues, particularly the brain, eye, and liver. The ATP7B gene for Wilson disease encodes a copper-transporting ATPase in the hepatocytes. With mutations in this gene, copper cannot be secreted into plasma. Ceruloplasmin is an a2 -globulin that carries copper in plasma. Because copper cannot be secreted into plasma, ceruloplasmin levels are low. Chronic liver disease and panlobular emphysema may occur in a1 -antitrypsin deficiency. An increased a-fetoprotein is a marker for hepatocellular carcinoma. Increased serum ferritin may indicate hereditary hemochromatosis. A positive finding for antimitochondrial antibody can be seen in primary biliary cirrhosis. A positive HBsAg result indicates HBV, which infects only the liver.

Teenagers and young adults are affected by acne vulgaris more often than other age groups, and males are affected more often than females. Propionibacterium acnes organisms break down sebaceous gland oils to produce irritative fatty acids, and this may promote the process. The food on the cruise probably did not play a role, but stress causes the lesions to worsen. Staphylococcus aureus and group A streptococci are implicated in the inflammatory skin condition known as impetigo, which can include pustules and a characteristic pale yellow-brown crust. Herpes simplex virus produces vesicular skin eruptions, most often in a perioral or genital distribution. Mycobacterium leprae causes leprosy, which is a chronic condition that can produce focal depigmentation and areas of skin anesthesia.

The major targets in primary sclerosing cholangitis are intrahepatic bile ducts, and ulcerative colitis coexists in 70% of cases. Ducts undergo destructive cholangitis that leads eventually to periductal fibrosis and cholestatic jaundice. Eventually, cirrhosis and liver failure can occur. The copper deposition is characteristic of Wilson disease, which is associated with chronic hepatitis and cirrhosis. Granulomatous bile duct destruction occurs in primary biliary cirrhosis. Interface hepatitis is characteristic of chronic active viral hepatitis. a1 -Antitrypsin deficiency with PAS-positive periportal globules is associated with cirrhosis. Portal bridging fibrosis with nodular regeneration defines cirrhosis.

The patient presents with a lesion of secondary syphilis known as condyloma lata. This stage is marked by painless, superficial lesions of the skin and mucosal surfaces. It occurs 2 to 10 weeks after the primary chancre in approximately 75% of untreated people. Skin lesions frequently occur on the palms or soles of the feet and may be maculopapular, scaly, or pustular. Moist areas of the skin, such as the anogenital region, inner thighs, and axillae, may have broad-based elevated plaques called condylomata lata. The original lesion, the painless ulcer or chancre, is characteristic of primary syphilis. Chancroid is a similar lesion to the primary lesion in syphilis, but instead is painful. Condyloma acuminatum (anogenital was) is a similarly named lesion often referred to as a venereal wa and is due to HPV. Papillary hidradenoma is a common benign tumor of the vulva, presenting as a nodule that may ulcerate and bleed.

His medical history is significant for atrial fibrillation; he was recently switched from rivaroxaban to warfarin due to the high cost of rivaroxaban.What is the most probable cause of the condition?

Malignancy is a recognized risk factor for venous thromboembolism (VTE), and VTE is the second leading cause of death in cancer patients. Procoagulant molecules expressed both by cancer cells and host tissue contribute to this condition. Low-molecular-weight heparin (LMWH) is the preferred anticoagulant for long-term treatment in patients with cancer. When compared with warfarin, LMWH reduces the rate of recurrent VTE without significant risk of bleeding. Newer anticoagulants such as rivaroxaban have not been adequately tested for cancer-induced VTE yet.Young patients with unprovoked VTE, a history of unexplained VTE, or family history of VTE raise the suspicion of an inherited hypercoagulable disorder. The common inherited hypercoagulable disorders are Factor V Leiden mutation, prothrombin gene mutation, protein S deficiency, protein C deficiency, antithrombin III deficiency, dysfibrinogenemia, and antiphospholipid antibody syndrome. When inherited hypercoagulable disorders are strongly suspected, tests for above mentioned disorders can be ordered. In the event of an acute thrombosis, however, it is not recommended to test for protein C, protein S, and anti-thrombin III since active coagulation can reduce the plasma concentration of these proteins resulting in false-positive result. To avoid confusion, it is recommended to order only Factor V Leiden mutation, prothrombin gene mutation, and antiphospholipid antibody with acute VTE or when patients are on warfarin.Warfarin-induced skin necrosis results from a transient hypercoagulable state. Warfarin initially affects all the vitamin K-dependent clotting proteins (Factors II, VII, IX, X, and proteins C and S). Since Protein C has a short half-life (8-12 hours), the serum protein C concentration drops quickly to 50% of normal in first 24 hours. Since circulating levels of other vitamin K-dependent proteins are still high, this gives rise to a hypercoagulable state which may cause microthrombi in the dermal and subcutaneous vessels, resulting in skin necrosis. The risk is particularly high in case of congenital protein C deficiency; nearly one-third cases of warfarin-induced skin necrosis are associated with congenital protein C deficiency.

This morning, she noted that her urine was brown in color, and she has also developed moderate, steady, pain of the right upper quadrant of her abdomen. She has not had any similar episodes in the past. On physical examination, the patient is noted to be jaundiced and to have an enlarged, tender liver. Blood chemistry studies are notable for alanine aminotransferase (ALT) of 15,000 mIU/L, aspaate aminotransferase (AST) of 11,000 mIU/L, and alkaline phosphatase of 100 U/L.

This person's markedly elevated AST and ALT with modest elevation of alkaline phosphatase strongly suggests that she has acute hepatitis. The clinical presentation with flu-like symptoms that progress to jaundice is also typical. Chronic hepatitis and cirrhosis would present more insidiously and would not have the extremely high elevations of AST and ALT. Gallstone disease can cause acute abdominal pain, and occasionally jaundice (if a small stone occludes the common bile duct), but would not usually cause the very high elevations of AST and ALT seen in this patient.

Hypersensitivity pneumonitis is an inflammatory disorder of the lungs involving alveolar walls and terminal airways that is caused by repeated exposure to organic agents. In this example of "farmer's lung," the inhalation of antigens present in moldy hay such as thermophilic actinomyces ox Aspergillus species are the causative agents. When exposure to moldy hay is stopped, symptoms and signs of farmer's lung all tend to abate and complete recovery usually follows. In acute syndromes, the presentation is 4-8 hours after exposure. Symptoms include fever, chills, malaise, cough, and dyspnea without wheezing. The rate of disease depends on rainfall (which promotes fungal growth) and agricultural practices related to turning and stacking hay. In acute and subacute presentations, removing exposure to the antigen will result in complete recovery. COPD and bronchiectasis are less likely given the absence of prior smoking exposure or lung injury, and both of these disorders usually do have an associated pulmonary infiltrate on CXR unless there is an concomitant lung infection. Asthma can cause wheezing symptoms, and even have mold or dust as triggers but again there is no infiltrate seen on the CXR.

single
This patient with well advanced cirrhosis and portal hypertension has developed the onset of renal insufficiency consistent with hepatorenal syndrome. This occurs during the end stages of cirrhosis and is characterized by diminished urine output and low urinary sodium. In the setting of end-stage liver disease, renal vasoconstriction occurs, and the distal convoluted tubule responds by conserving sodium. Unless the renal function is allowed to deteriorate further, liver transplantation will reverse this vasoconstriction and kidney function will return to normal. A large volume paracentesis may relieve the ascites but will have no significant benefit on the impaired renal function. There are no indications in this question to suggest that the patient requires acute hemodialysis.  A mesocaval shunt  is a surgical procedure that may decompress the portal pressure but will not have any benefit on renal function. Renal transplantation is of no value in this patient since the underlying lesion is in the liver; the kidneys will return to normal function if there is improvement in hepatic function.

This is a case of megaloblastic anemia due to Diphyllobothrium latum infection. Lab findings show increased mcv, LDH, indirect bilirubin and normal iron studies, and low reticulocyte, WBC and platelet count. Pbs shows hypersegmented neutrophil. Bone marrow aspiration study shows megaloblasts. DIPHYLLOBOTHRIUM LATUM Humans acquire the infection by ingesting infected raw or smoked fish with plerocercoid larva which is the infective form. Within 3-5 weeks, the tapeworm matures into an adult in the human intestine. Because the tapeworm absorbs large quantities of vitamin B12 and interferes with ileal B12 absorption, vitamin B12 deficiency can develop. Praziquantel (5-10 mg/kg once) is highly effective. Parenteral vitamin B12 should be given if B12 deficiency is manifest.

A 42-year-old woman has noted increasing fullness in her neck for the past 7 months. On physical examination, her thyroid gland is diffusely and asymmetrically enlarged and nodular. There is no lymphadenopathy. She undergoes thyroidectomy. Gross examination of the thyroid shows a multicentric thyroid neoplasm; microscopically, the neoplasm is composed of polygonal-to spindle-shaped cells forming nests and trabeculae. There is a prominent, pink hyaline stroma that stains positively with Congo red. Electron microscopy shows varying numbers of intracytoplasmic, membrane-bound, electron-dense granules. Immunohistochemical staining for which of the following antigens is most useful for the diagnosis of this neoplasm?
Calcitonin

Medullary carcinomas are derived from the C cells, or parafollicular cells, of the thyroid, with embryologic origin from the neural crest. Therefore they have the neuroendocrine function, including synthesis of calcitonin. An amyloid stroma is a common feature of this tumor. These tumors occur sporadically in about 70% of cases, but they can be familial and part of multiple endocrine neoplasias types 2A and 2B. CD3 is a useful marker for some lymphoid neoplasms. Although various tissues may show positivity for estrogen receptors, this finding has no clinical significance in the thyroid. Staining for parathyroid hormone is useful to determine if a parathyroid carcinoma is present. Vimentin is a marker for sarcomatous neoplasms, and cytokeratin is a useful marker to determine if a neoplasm is epithelial.

The rash and the Koplik spots on the buccal mucosa are characteristic findings in measles (rubeola), a childhood infection. It occurs only sporadically when immunizations have been administered to a large part of the population. The severity of the illness varies, and measles pneumonia may complicate the course of the disease, which in some cases can be life-threatening. Mononucleosis, which results from Epstein-Barr (EBV) virus infection, is more likely to occur in adolescence. Mumps produces parotitis and orchitis. Varicella-zoster virus infections in children manifest as chicken-pox. Rubella, also called German measles, is a much milder infection than rubeola.

Subacute sclerosing panencephalitis causes involuntary spasmodic movements and progressive mental deterioration, frequently ending in death within a year. It usually occurs in children whose measles occurred at an early age (= 2 years). It occurs 6-8 years after the primary infection. It presents with nonspecific symptoms such as poor school performance or mood and personality changes. It then progresses to intellectual decline, seizures, myoclonus, ataxia, and visual disturbances. Continued deterioration results in inevitable death.

Following irreversible ischemic injury, the hea (and any other organ) displays an orderly sequence of events that progresses from necrosis of parenchymal cells to inflammatory reaction, granulation tissue, and scar healing. Although ischemic injury manifests with pain almost immediately following vascular occlusion, histologic evidence of necrosis lags behind the clinical symptoms. At 1 hour after ischemia, there is no morphologic change indicative of necrosis. The first signs of necrosis appear 12 hours after irreversible ischemia: myocytes appear intensely eosinophilic and wavy, but there is no inflammatory reaction yet. Acute inflammatory cells (neutrophils) infiltrate the infarcted area beginning 1 day and peaking at approximately 2-3 days after injury. This acute inflammatory response paially overlaps with the subsequent influx of lymphocytes and histiocytes. Reabsorption of necrotic myofibers by histiocytes, as well as proliferation of small blood vessels, marks early formation of granulation tissue at around 5 days.
