It will normally remain unchanged but will migrate into the deeper cortex over time due to the apposition of new fibers.Lamellar (Zonular) cataractIt is the most common developmental cataract.Opacities are located in one layer of lens fibers, often as "riders" only in the equatorial region.Nuclear cataractIn the fourth decade of life, the pressure of peripheral lens fiber production causes hardening of the entire lens, especially the nucleus. The nucleus takes on a yellowish brown color (brunescent nuclear cataract). This may range from reddish brown to nearly black discoloration of the entire lens (black cataract). Nuclear cataracts develop very slowly. Due to the lenticular myopia, near vision (even without eyeglasses) remains good for a long time.Cortical cataractNuclear cataracts are often associated with changes in the lens cortex. It is interesting to note that patients with cortical cataracts tend to have acquired hyperopia in contrast to patients with nuclear cataracts, who tend to be myopic.# Berlin's edema (commotio retinae) is a condition caused by blunt injury to the eye. Berlin's edema is an acute traumatic maculopathy characterized by retinal opacification. Histopathologic studies have shown that it is characterized by disruption of photoreceptor outer segments and retinal pigment epithelial damage.

6acd9d9b-1e92-4785-b24f-09cbead72547 | The following are attributes of hepatitis B infection except - | Establishes chronic infections in those infected as infants | HBcAg in serum indicate active infection | Can cause hepatocellular carcinoma | Alpha interferon is used for the treatent of chronic infection | 1b
| multi | Hepatitis B may cause an acute viral hepatitis; however, acute infection is often asymptomatic, paicularly when acquired at bih. Many individuals with chronic hepatitis B are also asymptomatic. The risk of progression to chronic liver disease depends on the source and timing of infection . Veical transmission from mother to child in the perinatal period is the most common cause of infection worldwide and carries the highest risk of ongoing chronic infection. In this setting, adaptive immune responses to HBV may be absent initially, with apparent immunological tolerance. Several mechanisms contribute towards this: Firstly, the introduction of antigen in the neonatal period is tolerogenic. Secondly, the presentation of such antigen within the liver, as described above, promotes tolerance; this is paicularly evident in the absence of a significant innate or inflammatory response. Finally, very high loads of antigen may lead to so-called 'exhaustion' of cellular immune responses. The state of tolerance is not permanent, however, and may be reversed as a result of therapy, or through spontaneous changes in innate responses, such as interferon alpha (IFN-a) and NK cells, accompanied by host-mediated immunopathology. Chronic hepatitis can lead to cirrhosis or hepatocellular carcinoma, usually after decades of infection . Chronic HBV infection is a dynamic process that can be divided into five phases ; these are not necessarily sequential, however, and not all patients will go through all phases. It is impoant to remember that the virus is not directly cytotoxic to cells; rather, it is an immune response to viral antigens displayed on infected hepatocytes that initiates liver injury. This explains why there may be very high levels of viral replication but little hepatocellular damage during the 'immune-tolerant' phase. Hepatitis B core antigen Hepatitis B core antigen (HBcAg) is not found in the blood, but antibody to it (anti-HBc) appears early in the illness and rapidly reaches a high titre, which subsides gradually but then persists. Anti-HBc is initially of IgM type, with IgG antibody appearing later. Anti-HBc (IgM) can sometimes reveal an acute HBV infection when the HBsAg has disappeared and before anti-HBs has developed Ref Davidson edition23rd pg 874 | Medicine | G.I.T |

Due to ACTH production by pituatory microadenoma (cushing disease) or by ectopic ACTH production. o ACTH stimulates the zona reticularis and zona fasciculata which results in either diffuse hyperplasia (25-40 gm) or nodular hyperplasia (30-50 gm) of adrenal. Primary pituitary adenoma Weight is less than 30 gm. Primary pituitary carcinoma -4 Weight is 200-300 gm. Exogenous glucocoicoid administration o Exogenously administered glucocoicoids inhibit the release of ACTH from pituitary by negative feed back mechanism. o So, there is no stimulatory signal on zona fasciculata and zona reticularis --> Both these layers undergo atrophy. o As zona glomerulosa function is independent of ACTH, its thickness remains normal. o Due to atrophy the weight of the gland is less than normal, i.e., < 4 gm. | Pathology | null |

Prolonged deficiency irreversibly damages a number of visual cells.
Severe deficiency of vitamin A leads to xerophthalmia. This is characterized by dryness in conjunctiva and cornea, and keratinization of epithelial cells.
In certain areas of conjunctiva, white triangular plaques known as Bitot's spots are seen.
lf xerophthalmia persisits for a long time, corneal ulceration and degeneration occur.
This results in the destruction of cornea ,a condition referred to as keratomalacia, causing total blindness
Vitamin A deficiency blindness is mostly common in children of the developing countries
Key Concept:
Night blindness (nyctalopia) is one of the earliest symptoms of vitamin A deficiency.

| single | Ans. a (Defects in phagolysosome function) (Ref. H - 17th/pg. Table 61-4)CHRONIC GRANULOMATOUS DISEASEChronic Granulomatous Disease presents before the age of 2 and can be transmitted through X-linked or autosomal pattern of inheritance. The defect lies in the inability to generate oxidative burst to kill organisms after being phagocytosed. The neutrophils lack enzyme NADPH oxidase, which plays an important role in production of microbicidal oxygen radicles. In the lab, the diagnosis can be confirmed through Nitro blue Tetrazolium reduction dye test, which will be negative. B cell and T cell functions are normal. Recurrent infections with catalase producing organisms are common. The NBT test is a measure of the respiratory burst in neutrophils and is used to screen for CGD. Neutrophils will reduce the dye NBT, a clear yellow water-soluble compound, to formazan upon stimulation of the respiratory burst. Formazan thus forms precipitates as a dark blue granular substance, which remains trapped in the cytoplasm. Patients with CGD lack a component of the oxidase system, which produces super oxide anion and thus cannot reduce NBT to formazan. Results are interpreted as follows: Normal (positive test) - cells with an orange-red nucleus and blue cytoplasm; Abnormal (negative test) - cells with an orange-red nucleus and colorless cytoplasm.Phagocytic cell deficiency:Leukocyte adhesion deficiency syndrome (type 1): Defect in LFA-1 integrin proteins on phagocytes. Presents early with recurrent bacterial infections, absent pus formation, and delayed separation of umbilicus.Chediak-Higashi disease:Autosomal recessive. Defect in microtubular function and lysosomal emptying of phagocytic cells. Presents with recurrent pyogenic infections by staphylococci and streptococci, partial albinism, and peripheral neuropathy.Chronic granulomatous disease:Defect in phagocytosis of neutrophils owing to lack of NADPH oxidase activity or similar enzymes. Presents with marked susceptibility to opportunistic infections with bacteria, especially S. aureus, E. coli, and Aspergillus.

| single | Transvaginal ultrasound Diagnosis of Ectopic pregnancy Pregnancy is definitely diagnosed by demonstrating intrauterine sac. - A normal intrauterine sac appears regular and well defined on ultrasound. So ectopic pregnancy can be diagnosed by demonstrating the absence of the intrauterine sac. In a woman in whom ectopic pregnancy is suspected because of pain, bleeding and positive pregnancy test, performance of vaginal sonography is the logical first step. If the sonography demonstrates live intrauterine fetus then ectopic pregnancy is extremely unlikely. Alternatively if the uterus is empty, an ectopic pregnancy can be diagnosed based on the visualization of an adnexal mass separate from the ovaries. 3-hCG hormones also play an impoant role in the diagnosis of pregnancy. fi HCG is a hormone secreted during pregnancy. It is positive in viually 100% of ectopic pregnancies. However, a positive test only confirms pregnancy and does not indicate whether it is intrauterine or extrauterine. In normal pregnancy pHCG should double up every 2 days but in ectopic pregnancy the rate of increase of fl hCG is slow. 13 hCG litres and ultrasound complement one another in detecting ectopic pregnancy and have led to earlier detection. By correlating fl hCG titres with ultrasound .findings an ectopic pregnancy can often be differentiated.from intrauterine pregnancy. An intrauterine sac should be visible by transvaginal ultrasound when the p hCG is approximately 1000 ml p/m1 and by transabdominal ultrasound approximately 1 week later when the fi hCG is 1800-3600 ?nip/int. Thus when an empty uterine cavity is seen with a 13 hCG litre above this threshold, the patient is likely to have an ectopic pregnancy. An empty cavity is less of a concern when a fihCG below this threshold is obtained. Serum progesterone measuremen A single measurement of serum progesterone may sometimes clarify the diagnosis when ectopic pregnancy is suspected, but Its accuracy is crude and the customary thresholds are < 5 ng/m and > 25 'tend. i.e.a value exceeding 25 ng/m1 excludes ectopic pregnancy with 97.5% sensitivity, value below 5 ng/ml occur in only .3 percent of normal regnancies. So normal pregnancies can be excluded if the progesterone level is below 5%. Surgical diagnosis of ectopic pregnancy :- Laparoscopy Direct visualization of the ,fallopian tubes and pelvis by diagnostic laparoscopy offers a reliable diagnosis in most cases of suspected ectopic pregnancy and a ready transition to definitive operative therapy. At times, identification of an early unruptured tubal pregnancy may be difficult even if the tube is .fully visualized. Inspite of the low morbidity and quick recovery time, laparoscopy usually is performed when, on the basis of noninvasive test or curettage results, the diagnosis of ectopic pregnancy is fairly ceain and medical therapy is not planned. In these cases laporoscopy is used both for therapeutic and diagnostic purpose. Laparotomy Open abdominal surgery is preferred when the woman is hemodynamically unstable or when laparoscopy is not feasible. Laparotomy should not be delayed while laparoscopy is performed in a woman with obvious abdominal hemorrhage that required immediate definitive treatment. Culdocentesis Culdocentesis is the transvaginal passage of a needle into the posterior cul-de-sac in order to determine whether free blood is present in the abdomen. This procedure is useful in the diagnosis of intraperitoneal bleeding. This procedure will reveal nonclotting blood if intra-abdominal bleeding has occurred. If culdocentesis is positive, laparoscopy or laparotomy should be performed immediately. Indeed, some argue that the main purpose of culdocentesis is, not in diagnosis but to better prioritize patients so that those with positive culdocentensis are taken immediately to the operating room. More on imaging procedures used in the diagnosis of ectopic pregnancy Vaginal sonography There has been much improvement in the early diagnosis of ectopic pregnancy using vaginal sonography. Its use results in earlier and more specific diagnosis of uterine pregnancy than abdominal sonography and it has become the imaging method of choice in early pregnancy.

Gyrate atrophy is an autosomal recessive dystrophy with peripheral choroidal degeneration. Laurence-Moon-Biedle syndrome is also inherited in autosomal recessive manner. Best's disease: It is caused by a mutation in the BEST1 (VMD2) gene, which encodes a transmembrane calcium-sensitive chloride channel (bestrophin) expressed in retinal pigment epithelium. Fundus examination ranges from a mild pigmentary disturbance within the fovea to the typical vitelliform or "egg yoke" lesion located in the central macula. Visual acuity is good and electro retinogram is normal. An abnormal electro-oculogram (EOG) is the hallmark of the disease.

Assessment of the family and the child's environment also provides important contextual information.
Topics covered in this section
This section covers the basic aspects of the general developmental assessment for young children with suspected developmental problems including possible autism. This section focuses on the general approach to the developmental assessment, including some specific components of such an assessment, but does not review information on specific autism assessment instruments.
Basis for guideline recommendations about the general developmental assessment
In the previous section on the use of autism assessment instruments, the guideline recommendations are based on the panel's interpretation of an extensive and systematic review of the scientific literature. The panel did not attempt to systematically evaluate the research evidence on effectiveness of the general developmental assessment methods discussed in this section as this was considered outside the specific scope of the guideline. Therefore, guideline recommendations in this section are based on the consensus opinion of the panel, using its collective knowledge and experience in assessing children with autism. In the panel's opinion, these recommendations reflect appropriate practices for assessing children with possible autism and are generally consistent with the scientific knowledge in this field. | Pediatrics | null |
