82a9a6ef-0e91-4565-8449-3835409aadbd | A baby is born with a large defect in the occipital bone through which the posterior poion of the brain has herniated. Which of the following terms best describes this lesion? | Encephalocele | Meningocele | Myelocele | Spina bifida | 0a
| single | The central neurons system and its overlying bones are subject to a variety of malformations and developmental diseases. The defect described in the question stem is a cranial encephalocele, in which brain herniates through a defect in the skull bones. The most common site for such a herniation is the occipital bone. Small defects in the occipital bone can be treated surgically, but large defects are very problematic, paicularly if significant herniation has occurred, since the brain becomes very vulnerable to trauma and infection. Meningocele is the term used when the meninges, but not the brain or spinal cord, herniate through a defect in the bony cranium or spinal column. Myelocele is the term used when the spinal cord herniates through a defect in the spinal column. Spina bifida refers to veebral defects through which the spinal cord or meninges may herniate.

a2245923-558f-4656-ae04-a803d47f34cb | A microbiology laboratory repos growth of Staphylococcus aureus from pus drained from a breast abscess. What is the most likely condition predisposing the patient to the development of a breast abscess? | Breast feeding | Endocarditis | Inflammatory breast carcinoma | Menopause | 0a
| single | Acute mastitis, frequently complicated by breast abscess formation, typically develops in the postpaum period, when the nipples are first subjected to the physical stresses of breast feeding. Bacteria enter the breast cracks in the nipple, and flourish in the microenvironment of the lactating breast. Acute mastitis causes redness, pain, and swelling in the affected breast; Staph. aureus is the most common pathogen. Although endocarditis could send septic emboli to the breast, Staph. aureus endocarditis is more commonly associated with bacteremia and fevers, proliferative glomerulonephritis, valvular dysfunction, and emboli to the brain, kidneys, hea, and gut. Inflammatory breast carcinoma does not invoke an inflammatory response, and it is not associated with an infection. Inflammatory breast carcinoma is characterized by tumor spread into the dermal lymphatics, producing diffuse induration and skin tenderness with the typical peau d'orange appearance. Mastitis arising in the perimenopausal period is usually a chronic mastitis, caused by obstruction of ducts due to inspissated secretions. Chronic mastitis is sterile. The breast tissue shows lymphocytes and plasma cells surrounding dilated ducts filled by cellular debris. Ref: Wyatt C., Butterwoh IV J.F., Moos P.J., Mackey D.C., Brown T.G. (2008). Chapter 17.

| multi | Oximes are used to displace organophosphates from the active site of acetylcholinesterase, thus reactivating the enzyme. Pralidoxime is a specific antidote that restores acetylcholinesterase activity by regenerating phosphorylated acetylcholinesterase and appears to prevent toxicity by detoxifying the remaining organophosphate molecules. Clinically, pralidoxime ameliorates muscarinic, nicotinic, and central neurologic symptoms. Pralidoxime is not recommended for asymptomatic patients or for patients with known carbamate exposures presenting with minimal symptoms. There is increased toxicity of pralidoxime in carbaryl poisoning. Ref: Robey III W.C., Meggs W.J. (2011). Chapter 195. Pesticides. In J.E. Tintinalli, J.S. Stapczynski, D.M. Cline, O.J. Ma, R.K.

| single | Carboxylation The only known biological role of vitamin K is as a cofactor for an enzyme carboxylase that catalyzes carboxylation of glutamic acid residues on vitamin K-dependent proteins. The key vitamin K-dependent proteins include: Coagulation proteins: factors II (prothrombin), VII, IX and X Anticoagulation proteins: proteins C, S and Z Bone proteins: osteocalcin and matrix-Gla protein Gas6 is a vitamin K-dependent protein that is found throughout the nervous system, as well in the hea, lungs, stomach, kidneys, and cailage. These proteins have in common the requirement to be post-translationally modified by carboxylation of glutamic acid residues (forming gamma-carboxyglutamic acid) in order to become biologically active. Prothrombin, for example, has 10 glutamic acids in the amino-terminal region of the protein which are carboxylated. Without vitamin K. the carboxylation does not occur and the proteins that are synthesized are biologically inactive. Carboxylation of glutamic acid residues is critical for the calcium-binding function of those proteins. Also Know There are two naturally occurring forms of vitamin K: - phylloquinone synthesized by plants - menaquinones synthesized by intestinal bacteria Synthetic forms of vitamin K are: - menadiotze - menadiol - menadiol acetate | Biochemistry | null |

Close to or within the portal tract, these are small clusters of modestly dilated bile ducts embedded in a fibrous, sometimes hyalinised stroma.
Although these "bile duct microhamartomas" may communicate with the biliary tree, they generally are free of the pigmented material tree.
They presumably arise from residual embryonic bile duct remnants. Occasionally, a triangular bile duct hamartoma may lie just under Glisson's capsule.
Polycystic liver disease
There are multiple diffuse cystic lesions in the liver.
Congenital hepatic fibrosis
Portal tracts are enlarged by irregular, broad bands of collagenous tissue, forming septa that divide the liver into irregular islands.
Variable numbers of abnormally shaped bile ducts are embedded in the fibrous tissue and are in continuity with the biliary tree.

Fluid overload may be the result of cardiac failure, pulmonary hypertension (even in the absence of right ventricular failure), renal failure, hypoalbuminaemia or drugs (calcium channel blockers, glucocorticoids, mineralocorticoids, non-steroidal anti-inflammatory drugs (NSAIDs) and others).
Approximately 60% of lean body weight is water, two-thirds of which is intracellular. Most of the remaining water is found in extracellular compartments in the form of interstitial fluid; only 5% of the body’s water is in blood plasma. As noted earlier, edema is an accumulation of interstitial fluid within tissues.
Increase in hydrostatic pressure are mainly caused by disorders that impair venous return. Local increases in intravascular pressure caused, for example, by deep venous thrombosis in the lower extremity can cause edema restricted to the distal portion of the affected leg.
Reduction of plasma albumin concentrations leads to decreased colloidal osmotic pressure of the blood and loss of fluid from the circulation.
Edema may result from lymphatic obstruction that compromises resorption of fluid from interstitial spaces.

| multi | Ans. c (Coronal tilt) (Ref. Bailey & Love surgery, 24th/pg. 375; Orthopedics by John Ebnezar - Pg.155)Malunion (gunstock deformity/cubitus varus) can result from tilt in the coronal plane, and is the most common late complication of supracondylar fracture.SUPRACONDYLAR FRACTURE OF HUMERUS# There are two types of supracondylar fracture--the extension type (95%), in which the anterior cortex fails first with resultant posterior displacement of the distal fragment, and the flexion type, in which the opposite occurs.# Extension type supracondylar fractures are classified using Gartland's classification:- Type I fractures are nondisplaced,- Type II fractures are displaced but hinged on the posterior cortex, and- Type III fractures are completely displaced, as in this case (have potentially serious complications).Early Complications# Vascular damage- As the distal fragment and forearm are pushed backward, the brachial artery and median nerve are pulled violently against the sharp lower edge of the proximal fragment. Circulation must be assessed looking for pulselessness, pallor, pain, paresthesia, and paralysis (the five p's), and capillary refill.# Compartment syndrome# Nerve damage- The median, radial, and ulnar nerves may be injured, with potential long-term pain and functional deficit. Fortunately, the injury is usually a neuropraxia, which recovers with conservative treatment.# Myositis ossificansLate Complications# Volkmann's ischemic contracture# Malunion- Cubitus varus (gun stock deformity) is the most common long-term complication resulting from a malunion of a supracondylar fracture of the humerus in children.- The deformity occurs as a result of residual coronal angulation. Corrective supracondylar osteotomy is performed mainly to improve the cosmetic appearance and not for functional reasons. The most popular method was lateral closing wedge osteotomy but it needs detailed preoperative planning, careful surgical technique but can still cause recurrent varus and lateral condylar prominence in older children.- In Dome osteotomy vulnerability of the radial nerve is the problem. Osteotomy with T-plate fixation gives very good correction of varus deformity, with stable fixation and good functional result but care must be taken to avoid injury to the radial nerve.# Supracondylar fracture of humerus undergoes medial tilt and can lead to varus deformity.- It can cause tardy ulnar nerve palsy.Rx of Supracondylar Fracture: | Orthopaedics | Injuries Around Arm & Elbow |
