Which of the following is a manifestation of 22q11 mutation syndrome?
|
Chromosome 22q11.2 deletion syndrome encompasses a spectrum of disorders that result from a small deletion of band q11.2 on the long arm of chromosome 22. It is also called as Velocardiofacial syndrome or DiGeorge syndrome It is characterized by Dysmorphogenesis of the 3rd and 4th pharyngeal pouches resulting in following features: C: Cardiac anomaly/cono-truncal anomaly A:Abnormal facies T: Thymic hypoplasia/T cell abnormality C: Cleft palate H: Hypocalcemia 22: Chromosome 22

An 8-year-old child has had abdominal pain and dark urine for 10 days. Physical examination shows blotchy purple skin lesions on the trunk and extremities. Urinalysis shows hematuria and proteinuria. Serologic test results are negative for MPO-ANCA (P-ANCA) and PR3-ANCA (C-ANCA). A skin biopsy specimen shows necrotizing vasculitis of small dermal vessels. A renal biopsy specimen shows immune complex deposition in glomeruli, with some IgA-rich immune complexes. Which of the following is the most likely diagnosis?
|
In children, Henoch-Schonlein purpura is the multisystemic counterpart of the IgA nephropathy seen in adults. The immune complexes formed with IgA produce the vasculitis that affects mainly arterioles, capillaries, and venules in the skin, gastrointestinal tract, and kidney. In older adults, giant cell arteritis is seen in external carotid branches, principally the temporal artery unilaterally. Polyarteritis nodosa is seen most often in small muscular arteries and sometimes veins, with necrosis and microaneurysm formation followed by scarring and vascular occlusion. This occurs 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 coronary and renal arteries, with granulomatous inflammation, aneurysm formation, and dissection. Telangiectasias are small vascular arborizations seen on the skin or mucosal surfaces.

A 55-year-old woman presents to the clinic for evaluation of several weeks of fever, abdominal pain, weight loss, and lack of energy. Three days prior to the assessment, she developed a left foot drop. Her blood pressure is 160/90 mm Hg, pulse 80/min, and the physical examination confirms left peroneal nerve damage and a bilateral sensory neuropathy in both legs. There are no skin rashes. Laboratory evaluation reveals an ESR of 105 mm/h, WBC of 14,000/mL, and negative serologic tests for antineutrophil cytoplasmic antibody (ANCA) and ANA. The eosinophil count is normal, and urinalysis is negative for casts, protein, and red cells. A clinical diagnosis of polyarteritis nodosa is made. Which of the following is the most likely mechanism for renal injury in this condition?
|
This patient has polyarteritis nodosa (PAN) and in classic PAN, unlike microscopic polyangiitis, both small and medium vessels are involved. The renal lesions are ischemic secondary to fibrinoid necrosis of the vessels. In microscopic polyangiitis, a diffuse glomerulonephritis is frequently present. The most common organ systems involved are the kidneys, musculoskeletal system, and peripheral nervous system.

Robe Koch assistant advised him to use agar instead of gelatin for solidifying culture media for cultivation of bacteria because
|
Gelatin was the substance originally used to gel culture media. However, gelatin is liquid at 35oC., the optimum temperature for many bacteria. In addition, some bacteria are capable of liquifying the gelatin, making it an unsuitable solidifying agent. Agar has neither of these drawbacks. Agar is preferred over gelatin, as it is bacteriologically ine, melts at 98degC and usually solidifies at 42degC.

Mineral oils are used in mosquito control measure as -
|
Mineral oils are used as chemical control against mosquito larvae. The mineral oil application to water is the oldest method to control mosquito. oils used are diesel oil, fuel oil, kerosene oil, and crude oils. Special mosquito larvicidal oils are also available. Oil kills larvae and pupae within a sho time after application. When applied on water oil spreads and forms a thin film, which cuts off the air supply to mosquito larvae and pupae. Since the life cycle of a mosquito is about 8 days, its customary to apply oil once in a week on all breeding places. Other anti-larval measures include source reduction, using Paris green, and synthetic insecticides. Biological control with larvivorous fishes like Gambusia and Lebister.

A female comes with normal breast development but scanty pubic hair. What is the most likely diagnosis ?
|
Androgen insensitivity syndrome (AIS), formerly known as testicular feminization, is an X-linked recessive condition resulting in a failure of normal masculinization of the external genitalia in chromosomally male individuals. Adolescent patients have no pubic and axillary hair, with otherwise scanty body hair, and lack acne, although breasts are normal as a result of conversion of testosterone to estradiol. Mullerian agenesis is characterized by a failure of the mullerian ducts to develop, resulting in a missing uterus and fallopian tubes and variable malformations of the upper poion of the vagina. An individual with this condition is hormonally normal; that is, they will enter pubey with development of secondary sexual characteristics including thelarche and adrenarche (pubic hair). Gonadal dysgenesis is characterized by a progressive loss ofprimordial germ cells on the developing gonads of an embryo.The accompanying hormonal failure also prevents the development of secondary sex characteristicsin either sex, resulting in a sexually infantile female appearance and infeility. Failure to develop secondary sex characteristics (sexual infantilism) is typical in Turner's syndrome.

Which of the following clotting factors helps in bridging the fibrin in a clot and stabilizes the clot?
|
Factor XIII is also called as fibrin stabilizing factor. It is activated by thrombin. Activated factor XIII strengthens the fibrin reticulum. The fibrin monomer molecules are initially held together by weak non covalent hydrogen bonding, and the newly formed fibers are not cross linked with each other. Therefore as a result, the clot is weak and can be broken apa easily. The activated factor XIII acts as an enzyme to cause covalent bonds between more and more fibrin monomer molecules as well as multiple cross-linkages between adjacent fibrin fibers, adding strength to the fibrin mesh work.

Best screening test for pheochromocytoma?
|
Ans: a (Urinary VMA estimation)Ref: Vasudevan & Sreekumari, 6th edi., Pg. 207Vanillyl mandelic acid (VMA) in urineVMA is the main urinary metabolite of the norepinephrine pathway. Metanephrine is acted upon by mono amine oxidase to form(VMA). Normal level of excretion of VMA is 2-6 mg/24 hr.lt is increased in pheochromocytoma and in neuroblastoma.Patient is asked to refrain from intake of chocolate, coffee, banana, vanilla ice creams, citrus fruits (lime & orange). These items contain vanillin, which produces very high value of VMA in urine. Patient should not take aspirin or drugs containing phenol ring.Homovanillic acid (HVA) in urine: HVA is the main urinary metabolite of dopa and dopamine pathway It is increased in neuroblastoma, malignant pheochromocytoma and ganglioneuroma.It is useful to predict prognosis of neuroblastoma. Drugs increasing the value are -L-dopa, disulfiram and reserpine.

A 68-year-old male patient in the cardiology ward complains at each mealtime of difficulty in swallowing (dysphagia). Radiographic studies reveal significant cardiac hypertrophy. A barium swallow, followed by radiographic examination of the thorax, reveals esophageal constriction directly posterior to the heart. Which of the following is the most likely cause of the patient's dysphagia?
|
Mitral stenosis leads to left atrial dilation, which can exert a compressive effect on the esophagus. The pulmonary valve is located between the outflow tract of the right ventricle and the pulmonary trunk. The aortic valve is located between the left ventricle and the aorta. Anterior interventricular (left anterior descending) and posterior interventricular (posterior descending) arterial occlusions can cause a myocardial infarction, but not dysphagia. In the normal position of the heart the left atrium lies most posteriorly. Therefore, a stenosis of the mitral valve (atrioventricular valve between left atrium and left ventricle) would lead to enlargement of the left atrium, which would in turn impinge upon the esophagus. A stenosis of the pulmonary valve would have no effect upon the esophagus because of the anterior position of the pulmonary trunk in the thorax. Regurgitation through any valve will ultimately decrease systemic blood flow. An occlusion of a coronary artery will lead to ischemia and possibly myocardial infarction.

A 27 yr old boy has itchy, excoriated papules on the forehead and exposed pas of the arms and legs for 3 years. The disease was most severe in the rainy season and improved completely in winter. What is the most likely diagnosis?
|
In this case, diagnosis can be made by excluding each option. This patient is least likely to have scabies, as it does not produce lesions on the face in adults. Atopic dermatitis is unlikely since he is giving a history of similar lesions only since 3 years. In atopic dermatitis lesions first appears in infancy and then continues into childhood and adulthood. By this time lesions become more and more lichenified. Uicaria is characterised by the presence of evanescent wheals due to edema of dermis, and it last only for 24- 48 hours. So the most appropriate diagnosis would be insect bite hypersensitivity. In this condition the characteristic lesions are itchy persistent papules with a central punctum, seen mainly on exposed pas of the body and aggrevated during rainy season.

Most important layer of a slow sand filter is -
|
This is confusing one because of the following statements of Park.
"The most important part of the filter is the sand bed" - Park
"The vital layer is the heart of the slow sand filter" - Park
Following statement may help in choosing the answer : -
"Vital layer is the layer that provides the effective purification in potable water treatment, the underlying sand layer providing the support medium for this biological treatment layer" - Water & Health 3rd/e 733.
Read the mechanism of action of slow sand filter and there will be no confusion.
Mechanism of action of slow sand filter
Slow sand filter work through the, formation of a gelatinous layer called vital layer or hypogeal layer or Schmutzdecke in the top few cm of sand layer.
This layer is formed in the first 10-20 days of operation.
The formation of vital layer is known as "Ripening of the filter".
This vital layer consists of bacteria, fungi, Protozoa, and a range of aquatic insect larvae.
As waste passes through vital layer, particles of foreign matter are trapped in the mucilaginous matrix and dissolved organic material is absorbed and metabolized by bacterial, fungi and protozoa → Vital layer has mechanical (physical) as well as biological action.
So, the vital layer acts as the heart of slow sand filter.

A rickshaw is run over legs of a child making markings of tyre on the legs. Which type of injury is this?
|
Patterned abrasion. Patterning of abrasions The patterning of abrasions is clearer than that of bruises because abrasions frequently take a fairly detailed impression of the shape of the object causing them and, once inflicted, do not extend or gravitate; therefore, they indicate precisely the area of application of force. An abrasion (or a graze) is a superficial injury involving only the outer layers of the skin and not penetrating the full thickness of the epidermis. Patterned Abrasions: Patterned abrasions occur when the force is applied at or around right angle to the surface of skin. The classical example of this is seen in traffic accidents when tyre of a motor car passes over the skin leaving the pattern when the skin has been squeezed into the grooves of the rubber tread. Pressure Abrasions (Imprint Abrasions): When the impact is veical to the skin surface, the epidermis gets crushed and pressure type of abrasions result and the imprint of the impacting object may be produced. These may be seen in manual strangulation (abrasions produced by fingernails) and in hanging, where the weave of the ligature material may be reproduced.

DNA content is more than normal cells. Examples of tissues Myocardium, skeletal muscles, Breast, endometium, liver, kidney. Why do some tissues undergo hyperophy, while others undergo hyperplasia ? o The cells that have limited capacity of proliferation (e.g., myocardial cells & skeletal muscle cells) can not increase their number, So they are not able to undergo hyperplasia. But these cells can increase in size in response to increased demand, So they can undergo hyperophy. o The cells capable of division (hepatocytes, renal tubular epithelial cells, smooth muscles of uterus) have both the propeies, i.e., to increase the number as well as the size. So, tissues containing these cells can undergo hyperophy or hyperplasia or both. o For example, both hyperplasia and hyperophy occur in endometrium of pregnant uterus.

Which of the following is used for initial screening of auditory function in a neonate?
|
Most screening programmes for newborn hearing ability uses otoacoustic emission as the initial test. It this test fails then auditory brainstem response is used for screening. Otoacoustic emissions are low level sound emitted spontaneously by the cochlea on presentation of an auditory stimulus. Persons with normal hearing produce oatoacoustic emissions whereas those who have hearing loss of 30-40db HL or greater do not produce OAE. Auditory brainstem response testing is used with babies between the ages of bih and 5 months. It is the electrophysiological response to an acoustic stimulus and originates from the eight cranial nerve and auditory brain stem. It can be used to determine the degree of hearing loss at different audiometric frequencies.

Which vitamin is given in type 2B familial hyperlipidemia?
|
Niacin or nicotinic acid is vitamin. Niacin is conveed to its coenzyme forms NAD and NADPTreatment of hyperlipidemia:Niacin (at doses of 1.5 g/day or 100 times the Recommended Dietary Allowance or RDA) strongly inhibits lipolysis in adipose tissue--the primary producer of circulating free fatty acids. The liver normally uses these circulating fatty acids as a major precursor for triacylglycerol synthesis. Thus, niacin causes a decrease in liver triacylglycerol synthesis, which is required for very-low-density lipoprotein (VLDL, see p.231) production. Low-density lipoprotein (LDL, the cholesterolrich lipoprotein) is derived from VLDL in the plasma. Thus, both plasma tri acylglycerol (in VLDL) and cholesterol (in VLDL and LDL) are lowered. Therefore, niacin is paicularly useful in the treatment of Type IIb hyperlipoproteinemia, in which both VLDL and LDL are elevated. Ref: Lippincott, 5th edition, page no: 380

Maximum tensile strength is recovered in wound area during what period after an injury?
|
Net collagen accumulation, however, depends not only on increased collagen synthesis but also on decreased degradation. When sutures are removed from an incisional surgical wound, usually at the end of the first week, wound strength is approximately 10% that of unwounded skin. Wound strength increases rapidly over the next 4 weeks, slows down at approximately the third month after the original incision, and reaches a plateau at about 70% to 80% of the tensile strength of unwounded skin. Lower tensile strength in the healed wound area may persist for life. Ref: Robbins 8th edition Chapter 3.

Characteristic of acute inflammation is
|
Ref Robbins 8/e p 45 ,9/e p74 The acute inflammatory response rapidly delivers leuko- cytes and plasma proteins to sites of injury. Once there, leukocytes clear the invaders and begin the process of digesting and getting rid of necrotic tissues. Acute inflammation has two major components (Fig. 2-2): * Vascular changes: alterations in vessel caliber resulting in increased blood flow (vasodilation) and changes in the vessel wall that permit plasma proteins to leave the cir- culation (increased vascular permeability). In addition, endothelial cells are activated, resulting in increased adhesion of leukocytes and migration of the leukocytes through the vessel wall. * Cellular events: emigration of the leukocytes from the circulation and accumulation in the focus of injury (cel- lular recruitment), followed by activation of the leuko- cytes, enabling them to eliminate the offending agent. The principal leukocytes in acute inflammation are neu- trophils (polymorphonuclear leukocytes). Stimuli for Acute Inflammation Acute inflammatory reactions may be triggered by a variety of stimuli: * Infections (bacterial, viral, fungal, parasitic) are among the most common and medically impoant causes of inflammation. * Trauma (blunt and penetrating) and various physical and chemical agents (e.g., thermal injury, such as burns or frostbite; irradiation; toxicity from ceain environ- mental chemicals) injure host cells and elicit inflamma- tory reactions. * Tissue necrosis (from any cause), including ischemia (as in a myocardial infarct) and physical and chemical injury * Foreign bodies (splinters, di, sutures, crystal deposits * Immune reactions (also called hypersensitivity reactions) against environmental substances or against "self" tissues. Because the stimuli for these inflammatory responses often cannot be eliminated or avoided, such reactions tend to persist, with features of chronic inflam- mation. The term "immune-mediated inflammatory disease" is sometimes used to refer to this group of disorders. Although each of these stimuli may induce reactions with some distinctive characteristics, in general, all inflamma- tory reactions have the same basic features. In this section, we describe first how inflammatory stimuli are recognized by the host, then the typical reac- tions of acute inflammation and its morphologic features, and finally the chemical mediators responsible for these reactions.

Deficiency of the 'intrinsic factor of Castle' causes:
|
Answer is B (Pernicious Anemia) Deficiency of Intrinsic factor leads to a specific form of vitamin B12 deficiency megaloblastic anemia called `Pernicious Anemia'. Pernicious Anemia also known as Addison's Anemia is a megaloblastic anemia due to deficiency of intrinsic factor (secreted by parietal cells of gastric mucosa) that is essential for vitamic B12 absorption. Note: 'Intrinsic factor' was first described by castle & coworkers and hence intrinsic factor is also called Intrinsic factor of Castle.

LEEP Repeat All India 2009 "Although CIN can be treated with a variety of techniques, the preferred treatment for CIN 2 and 3 has become LEE?" - Novak's Gynecology p582 Though the patient is 35 yrs old and has completed her family, still hysterectomy won't be treatment of choice as-"Hysterectomy is currently considered too radical .for treatment of CIN"Novak's Gynecology p.585 Following are some situations in which hysterectomy remains a valid and appropriate method of treatment for CIN Microinvasion CIN 3 at limits of conizution specimen in selected patients Poor compliance with follow-up Other gynecologic problems requiring hysterectomy, such as fibroids, prolapse, endometriosis, and pelvic inflammatory disease Cervical intraepithelial neoplasia(CIN) Invasive squamous cell cervical cancers are preceded by a long phase of preinvasive disease, collectively referred to as cervical intraepithelial neoplasia (CIN). Histopathologically a pa or the full thickness of cervical squamous epithelium is replaced by cells showing varying degree of dysplasia, with intact basement membrane. CIN may be suspected through cytological examination using the Pap smear test or through colposcopic examination. Cervical cytology is the most efficacious and cost-effective method for cancer screening. Final diagnosis of CIN is established by the histopathological examination of a cervical punch biopsy or excision specimen. Additionally, human papilloma virus (HPV) testing can be performed in order to better triage women with early cytologic changes. Cervical Cytology Screening (American College of Obstetricians and Gynecologists Guideline) Initial screening Age 21 or 3 y after vaginal sex Interval Every year Every 2-3 y after age 30 with 3 consecutive normals Discontinue No upper limit of age Comparison of Cytology Classification Systems (in simplified form) Bathesda CIN llysplasia Limit of histologic changes *LSIL CIN 1 Mild Basal 1/3rd of sq. epithelium HSIL ON 2 Moderate Basal 1/2 to 2/3rd CIN3 Severe Whole thickness except one or two superficial layers CIS Whole thickness LSIL - Low grade squamous intraepithelial lesion HSIL - High grade squamous intraepithelial lesion CIS - Carcinoma in situ *LSIL incorporates HPV changes (koilocytotic atypia) along with CIN I. Role of HPV HPV infection is found in approx. 90% cases of intraepithelial neoplasia. Type H&18 are most commonly associated. HPV-18 is more specific than HPV-16 for invasive tumors. In most women, the HPV infection clears in 9 to 15 months. Only a minority of women exposed to HPV develop persistent infection that may progress to CIN. Type-16 is the most common HPV type found in women with normal cytology. Treatment CIN 1 Spontaneous regression of CIN 1 is seen in 60% to 85% of cases, typically within 2yrs. So patients who have biopsy diagnoses of C1N 1 are kept under observation with: Pap testing performed at 6 and 12 months Or HPV DNA testing at 12 months After two negative test results or a single negative HPV DNA test, annual screening may be resumed. Women with persistent CIN 1 after 24 months should be treated with a local ablative method. CIN 2 and3 CIN 2&3 carries a much higher probability of progressing to invasive cancer. All CIN 2 and 3 lesions require t reatment. LEEP ( loop electrosurgical excision procedure) is the preferred treatment for CIN 2 and 3. Because all therapeutic modalities carry an inherent recurrence rate of upto 10%. cytologic follow-up at about 3-month intervals for 1 year is necessary. Cryotherapy Considered acceptable therapy when the following criteria are met: - Cervical intraepithelial neoplasia, grade 1 to 2 - Small lesion Ectocervical location only - Negative endocervical sample - No endocervical gland involvement on biopsy Laser Ablation It has been used effectively for the treatment of CIN .But because of the expense of the equipment as well as necessity for special training, laser ablation has fallen out of or. Laser has been widely replaced by LEEP. Laser Excisional Conization Rather than using laser for vaporization leading to ablation, it can be used to excise a conization specimen. The ease of LEEP conization has significantly reduced the indications of laser conization. Loop electrosurgical excision( LEEP) LEEP, variably known as simply loop excision or LLETZ (large loop excision of the transformation zone), is a valuable tool for the diagnosis and treatment of CIN. It uses low-voltage, high-frequency, thin wire loop electrodes to perform a targeted removal of a cervical lesion, an excision of the transformation zone, or a cervical conization. This technique can be used in the outpatient setting Cold knife conization (scalpel) Conization is both a diagnostic and therapeutic procedure and has the advantage over ablative therapies of providing tissue for fuher evaluation to rule out invasive cancer. Conization is indicated for CIN 2&3 in following conditions: - Limits of the lesion cannot be visualized with colposcopy. - The squat-no-columnar junction (SCE) is not seen at colposcopy. - Endocervical curettage (ECC) histologic findings are positive for CIN 2 or CIN 3. - There is a substantial lack of correlation between cytology, biopsy, and colposcopy results. - Microinvasion is suspected based on biopsy, colposcopy, or cytology results. - The colposcopist is unable to rule out invasive cancer.

Herpes Simplex Viruses Infection Laboratory Diagnosis 1. Light Microscopy - cells from the base of the lesion, or wiped from a mucous surface, or biopsy material, may reveal intranuclear inclusions (Lipschutz inclusion bodies). Infected cells may show ballooning and fusion. 2. Electron Microscopy - Electron microscopy is not a sensitive tool for the detection of HSV, except in the case of vesicle fluids which often contain 108 or more paicles per milliliter. However, like light microscopy, electron microscopy cannot distinguish between the different viruses. 3. Direct examination by antigen detection - cells from specimens is treated in ice-cold acetone. FITC is generally used for staining of fixed material. It is more sensitive and specific than light and electron microscopy (90% sensitive, 90% specific), but cannot match virus culture. In terms of cost and technical expeise, it is very much more demanding. Cytopathic effect of HSV in cell culture, note the ballooning of cells (Couesy of Linda Stannard, University of Cape Town, S.A.) and positive immunofluorescence test for HSV antigen in the epithelial cell (Virology Laboratory, Yale-New Haven Hospital) Ref: mayo clinic

(A) Useful for rare diseases # CASE-CONTROL STUDY: Both exposure & outcome have occurred before the start of the study the study proceeds backwards from effect to cause; & it uses a control or comparison group to support or refute an inference.ADVANTAGES AND DISADVANTAGES OF CASE CONTROL STUDIESADVANTAGESDISADVANTAGES1. Relatively easy to carry out1. Problems of bias relies on memory or past records, the accuracy of wh'ch may be uncertain; validation of information obtained is difficult or sometimes impossible2. Rapid and inexpensive (compared with cohort studies)2. Selection of an appropriate control group may be difficult3. Require comparatively few subjects3. We cannot measure incidence, and can only estimate the relative risk4. Particularly suitable to investigate rare diseases or diseases about which little is known. But a disease which is rare in the general population (e.g., leukaemia in adolescents) may not be rare in special exposure group (e.g. prenatal X-rays).4. Do not distinguish between causes and associated factors5. No risk to subjects5. Not suited to the evaluation of therapy or prophylaxis of disease6. Allows the study of several different aetioiogical factors (e.g., smoking, physical activity and personality characteristics in myocardial infarction)6. Another major concern is the representativeness of cases and controls7. Risk factors can be identified. Rational prevention and control programmes can be established 8. No attrition problems, because case control studies do not require follow-up of individuals into the future9. Ethical problems minimal
