The prognosis of rhabdomyosarcoma is likely to be poor if the site of the tumour is:
The prognosis of rhabdomyosarcoma is likely to be poor if it involves the extremity. Extremity rhabdomyosarcomas in adolescents and young adults usually have alveolar histologic characteristics and carry a worse prognosis. Other poor prognostic factors associated with it includes age less than 1 and more than 10 years, alveolar histology, unorable primary size, size greater than 5cm and higher clinical group.

Peripoal fibrosis is caused by?
Methotrexate. This drug is a well-established cause of hepatic fibrosis and cirrhosis. These complications are best recognized following long-term use of the agent in inflammatory disorders such as psoriasis and rheumatoid ahritis, although cases have also followed administration for neoplastic diseases. The risk of liver damage depends largely on the dose, duration, and timing of therapy. In prospective studies, up to 25% of patients receiving a cumulative dose of 1.5 to 2 grams over five years have developed fibrosis or cirrhosis. The risk appears to be lessened by weekly, as opposed to daily, administration of the drug, and exacerbated by concomitant obesity or alcohol abuse. Methotrexate-induced hepatotoxicity is often clinically silent and, even in advanced disease, can exhibit an indolent clinical course. Evidence of poal hypeension or liver failure can nonetheless develop in some cirrhotic cases and may lead to death or the necessity for liver transplantation.

Stylohyoid ligament is derived from:
Ans. B 2nd branchial archRef: Gray's Anatomy, 41st ed. pg. 449* The stylohyoid ligament is a fibrous cord extending from the tip of the styloid process to the lesser cornu of the hyoid bone. It gives attachment to the highest fibres of the middle pharyngeal constrictor and is intimately related to the lateral wall of the oropharynx. Below, it is overlapped by hyoglossus.* The ligament is derived from the cartilage of the second branchial arch and may be partially calcified.

Mucoepidermoid carcinomas are composed of variable mixtures of squamous cells, mucus-secreting cells, and intermediate cells. "The low-grade mucoepidermoid carcinoma is composed of largely mucin-secreting cells, whereas in high-grade tumors, the epidermoid cells predominate."- Schwartz They are the most common malignant tumors of the salivary glands. Treatment The primary t/t of all salivary malignancy is surgical excision: for parotid malignancies- Superficial parotidectomy with preservation of CN VII. Total parotidectomy with nerve preservation if deep lobe is involved. for other salivary gland - Enbloc removal of the involved gland Neck dissection for lymph nodes is done clinically palpable nodes for high grade malignancies Radiation therapy is used postoperatively for specific indications high grade histology presence of extraglandular disease perineural invasion direct invasion of regional structure regional metastasis

A CKD patient had to undergo dialysis. His Hb was 5.2gm% so two blood transfusions were to be given. First bag was completed in 2 hours. Second was staed and midway he developed shoness of breath, hypeension. Vitals: BP 180/120 mm Hg and pulse rate 110/min. What is the cause?
This C.K.D patient has developed severe anemia which is a compensated hea failure state. The patient was given first unit of blood in two hours instead of standard four hours and he is already in compensated hea failure. The acute decompensation due to volume overloading that has subsequently occurred will result in pulmonary edema and shoness of breath. This presentation is called as transfusion associated circulatory overload. Ideally patients of CKD should be given erythropoietin injections to reduce the incidence of having severe anemia.

Child has lesion on buttocks since 2 year spreading peripherally with central scarring non symptomatic diagnosis-
Ans. is 'a' i.e., Erythema annuiase cetrifugam o Erythema annulare centrifugum : an asymptomatic or pruritic eruption of variable duration. The eruption may be associated with an underlying disease (eg, infection, malignancy, sarcoidosis, other systemic illness)o The eruption begins as erythematous papules that spread peripherally while clearing centrally. These lesions enlarge at a rate of approximately 2-5 mm/d to produce annular, arcuate, figurate, circinate, or polycyclic plaqueso Lesions demonstrate a predilection for the thighs and the legs, but they may occur on the upper extremities, the trunk, or the face. The palms and the soles are spared.o Erythema migrans: These lesions are typically less numerous, less circinate in configuration, and often accompanied by a history# of a tick bite.o Erythema gyratum repens: EAC can be distinguished from this condition by its slower rate of spread and by its less bizarre configuration. Also, erythema gyratum repens is almost always associated with an underlying malignancy.o Erythema marginatum rheumaticum: This is a nonscaling gymate erythema that by definition is found in association with rheumatic fever (10-18% of patients with rheumatic fever).

Most common inherited childhood tumor is:
Retinoblastoma is a neuroectodermal malignancy arising from embryonic retinal cells. It is the most common intraocular tumor in pediatric patients and causes 5% of cases of childhood blindness. Retinoblastoma is the prototype of hereditary cancers due to a mutation in the retinoblastoma gene (RB1), which is located on the long arm of chromosome 13 (13q14). Approximately 40% of retinoblastoma are inherited. Ref: Graham D.K., Quinones R.R., Keating A.K., Maloney K., Foreman N.K., Giller R.H., Greffe B.S. (2012). Chapter 31. Neoplastic Disease. In W.W.

All are true regarding menstrual regulation except:
Ans. is c i.e. Done upto 12 weeks Menstrual regulation - consists of aspiration of contents of uterine cavity by means of plastic cannula (Karman's cannula) and a plastic 50 cc syringe. It is carried out effectively within 14 days of beginning of LMP. A paracervical block or pre-operative sedative alone suffices but sometimes in apprehensive patient GA is required. Blood loss is less. It is included in methods of performing MTP. Friends-- there are 2 different methods -- menstrual regulation and manual vaccum aspiration. Both of them are based on same principle i.e. creating a vaccum which helps in extracting out the products of conception. But menstrual regulation is done within 2 weeks whereas, manual vaccum aspiration is a safe method uptil 12 wks.

Constitutional growth delay is a physiological variant of sho stature. Here children grow normally upto 6-12 months of life. Thereafter, there is deceleration such that the height and weight fall below the 3rd centile. By 3 yrs of age,normal height velocity is resumed and continues to grow below and parallel to the 3rd centile. Here pubey is delayed; And the bone age is consistent with the child&;s height age, but lower than the chronological age by 2-3 yrs , unlike in the familial sho stature. Hence IGF-1 produced is low for the chronological age but consistent with the bone age that corresponds to the height age. Ref. OP.Ghai ,9th edition, chapter 2

A 32-year-old male with a painless lymph node in the cervical region. Lymph node biopsy showed normal thyroid gland features. The thyroid is normal on palpation clinically. The diagnosis is
Thyroid tissue present in cervical lymph nodes in the face of a clinically normal thyroid gland is a metastasis from an occult primary thyroid carcinoma Occasionally, a metastatic papillary thyroid cancer manifests as a painless lateral neck mass that is clinically detected before detecting the primary thyroid lesion. Comment: Normal thyroid tissue is a trap by the examiner, remember in young people papillary thyroid cancer mostly is well differentiated. Well, differentiated cells look like normal cells and tend to grow .and spread more slowly than poorly differentiated cells (anaplastic carcinoma).

The 27-year-old male triathlon competitor complained that he frequently experienced deep pains in one calf that almost caused him to drop out of a regional track-and-field event. Doppler ultrasound studies indicated, and surgical exposure confirmed, the existence of an accessory portion of the medial head of the gastrocnemius that was constricting the popliteal artery. Above the medial head of the gastrocnemius, the superior medial border of the popliteal fossa could be seen. Which of the following structures forms this border?
The tendons of the semitendinosus and semimembranosus provide the superior medial border of the popliteal fossa. The semitendinosus inserts with the pes anserinus on the proximal, medial tibia. The semimembranosus inserts on the tibia posteriorly. The biceps femoris forms the superior lateral border of the fossa, as the tendon passes to insertion on the fibula. The plantaris arises from the femur just above the lateral head of the gastrocnemius, passing distally to insert on the calcaneus via the tendo Achilles. The popliteus arises from the tibia and passes superiorly and laterally to insert on the lateral condyle of the femur, with a connection to the lateral meniscus.

Frontal lobe function
The frontal lobe plays a large role in voluntary movement. It houses the primary motor coex. The function of the frontal lobe involves the ability to project future consequences resulting from current actions, the choice between good and bad actions (or better and best) (also known as conscience), the override and suppression of socially unacceptable responses, and the determination of similarities and differences between things or events.

In exhausted child with severe bronchiolitis, for every 10 mm Hg increase in PCO2, how many milliEq of bicarbonate will increase:-
Bronchiolitis is most common type of acute lower respiratory tract infections in children and young infants. Most common causative agent is respiratory syncytial virus. It's mostly seen in age group 6months to 3years C/F hyperinflated chest, respiratory distress of varying degree, hypoxia. Rx is mainly suppoive as no role of antibiotics as it's a viral infection. When pco2 is increased results is respiratory acidosis. In order to compensate that body tries to save more bicarbonate. Compensation in primary respiratory disorders For every 10 mm increase in pco2: DISORDER RESPIRATORY ACIDOSIS RESPIRATORY ALKALOSIS Acute HCO3 increases by 1 HCO3 decreases by 2 Chronic HCO3 increased by 3.5 HCO3 decreases by 4 Compensation in metabolic disorders DISORDER EXPECTED COMPENSATION Metabolic acidosis PCO2 = 1.5 * (HCO3) + 8 +/-2 Metabolic alkalosis pco2 increases by 7 for each 10 mEq/L increases in H From the above picture we see that for every acute process hco3 increases by 1 in respiratory acidosis

A 26 years old female suffers from PPH on her second postnatal day. Her APTT is prolonged while bleeding time and prothrombin time and platelet count are normal. Likely diagnosis is:
This is a case of acquired hemophilia A. Approximately 50 percent of acquired hemophilia A patients have an underlying condition, such as an autoimmune disorder (e.g., rheumatoid ahritis or systemic lupus erythematosus), malignancy, pregnancy, or a history consistent with a drug reaction. Patients with acquired hemophilia A have a prolonged aPTT caused by decreased or absent factor VIII activity in the intrinsic pathway of blood coagulation. The diagnosis of acquired hemophilia A is made by the demonstration of a solitary prolonged activated paial thromboplastin time (aPTT) that fails to correct on mixing with equal volumes of normal plasma (50:50 mix). The prothrombin time (PT), thrombin time (TT), and fibrinogen activity are all normal. Specific factor assays then are performed to determine whether a specific coagulation factor inhibitor or a lupus anticoagulant is present. Ref: Lollar P. (2010). Chapter 128. Antibody-Mediated Coagulation Factor Deficiencies. In J.T. Prchal, K. Kaushansky, M.A. Lichtman, T.J. Kipps, U. Seligsohn (Eds), Williams Hematology, 8e.

Which is true about measurement of BP with sphygmomanometer versus intra-aerial pressure measurements?
The reason for this is - "dissipation of pressure". When BP is measured by sphygmomanometry, the principle is 'balancing of pressure between the cuff and the brachial aery'. Suppose the pressure in the aery is, say, 100 mm Hg. When the pressure just outside the aery is 100 mm Hg, the aery will be occluded completely, or when the pressure outside the aery becomes just less than 100, the aery will open up and the flow will sta in the aery. However, for pressure just outside the aery to be 100, pressure in the cuff has to be about 106 mm Hg; about 6 mm Hg is dissipated in the intervening tissue (muscle, fat) between the cuff and the aery. Thus, if we are looking for a point at which the aery is just occluded (with aerial pressure being 100), the cuff pressure at which it happens is about 106 mm Hg Hence, by sphygmomanometry, the pressure measured is higher as compared to direct intravascular pressure measurement.

The upper cervix (endocervix) is lined by a simple columnar epithelium that contains mucous-secreting cells. In contrast, the lower cervix (ectocervix) is lined by a stratified squamous epithelium. The transition point between these two epithelia is known as the external os.

Regarding color vision, which of the following is TRUE?
The color opponent process is a color theory that states that the human visual system interprets information about color by processing signals from cones and rods in an antagonistic manner. The opponent-process theory states that the cone photoreceptors are linked together to form three opposing color pairs: blue/yellow, red/green, and black/white. The Young-Helmholtz theory postulates that the retina contains three types of cones, each with a different photopigment maximally sensitive to one of the primary colors (red, blue, and green). The sensation of any given color is determined by the relative frequency of impulses from each type of cone. Parvocellular ganglion cells receive color-specific signals from the three types of cones and relay them to the brain the optic nerve. Ref: Waxman S.G. (2010). Chapter 15. The Visual System. In S.G.

A young permanent incisor with an open apex has a pinpoint exposure due to a traumatic injury that occurred 24 hours previously. The best treatment is
Because the exposure site is likely significantly contaminated from the injury that occurred 24 hours previously, direct pulp capping with calcium hydroxide is contraindicated. A calcium hydroxide pulpectomy should not be the automatic procedure accomplished because continued root elongation and closure of the pulp canal will likely not occur. A calcium hydroxide pulpotomy is preferable for a traumatized tooth with an open apex with either a large exposure or a small exposure of several hours or days postinjury. Clinically, the tooth should be anesthetized and, under sterile conditions, and the clinician should open the pulp chamber in search of healthy pulp tissue. It is likely that vital tissue will be present within 24 hours of the injury.

Magnesium sulphate toxicity include all EXCEPT
MgSo4 acts by inhibition of neuromuscular transmission. NOTE: we monitor urine output while patient is on MgSO4, not because it is a sign of MgSO4 toxicity, but because oliguria is secondary to PIH (glomerular endotheliosis) and decreased urine output would decrease MgSO4 clearance and increase risk of toxicity.

A 7-year-old girl is brought with complaints of generalized swelling of the body. Urinary examination reveals grade 3 proteinuria and the presence of hyaline and fatty casts. She has no history of hematuria. Which of the following statements about her condition is true?
Grade 3 proteinuria, and the presence of hyaline and fatty cast in urine suggest the diagnosis of nephrotic syndrome. Most common cause of nephrotic syndrome in a child is minimal change disease ( not IgA nephropathy or Alport syndrome) In minimal change disease there is no deposition of immune reactants (immunoglobulin or complement), and serum complement levels are normal.

A 8.5-year-old child with missing 11 reported to your clinic. 21 erupted at 6.5 years of age. The child had trauma to 21, 4 months back and got it endodontically treated for that. What is your further treatment about missing teeth?
In question patient is of 8.5 years of age with missing right maxillary central incisor and has his Maxillary left Central Incisor Erupted on Schedule. Now non-eruption of a tooth beyond normal possible age of eruption while the contralateral tooth is being erupted on usual time can be due to its presence in impacted state or it can be congenitally missing. To rule out of these conditions radiographic examination is essential If tooth is impacted due to presence of any supernumerary tooth or due to any other region or tooth is congenitally missing we can plan further treatment with that situation.

`Coronory steal phenomenon' is caused by ?
Ans. is 'a' i.e., Dipyridamole o There are two types of vessels in coronary circulaton ? 1. Larger conducting aeries which run epicardially and send perforating branches. 2. Smaller resistance aerioles - These are perforating branches of conducting aeries. These aerioles supply blood to endocardium. o During ischemia, adenosine (a local mediator) causes dilatation of resistance aerioles in ischemic area only, tone of resistance vessels of nonischemic area does not change --> increased flow to ischemic area. o Dipyridamole is a powerful coronary dilator; increases total coronary flow by preventing uptake and degradation of adenosine. o It dilates resistance vessels in nonischemic zone as well ----> Dives the already reduced blood flow away from ischemic zone - Coronary steal phenomenon. o It has no effect on larger conducting vessels (contrast nitrates which dilate larger conducting vessels and cause redistribution of blood towards ischemic zone). o Dipyridamole inhibits platelet aggregation by increasing cAMP (by inhibiting phosphodiesterase) which potentiates PGI, and interferes with aggregation. o It is not useful as an antianginal drug (due to coronary steal phenomenon), but can be used for prophylaxis of coronary and cerebral thrombosis in post MI and post stroke patients as well as to prevent thrombosis in patients with prosthetic hea valve.
