mTOR INHIBITORS Sirolimus This new and potent immunosup-pressant is a macrolide antibiotic (like tacrolimus), which was earlier named Rapamycin. Mech of action:- It binds to immunophillin FKBP and the sirolimus-FKBP complex inhibits kinase called 'mammalian target of rapamycin' (mTOR). uses:- 1)For prophylaxis and therapy of graft rejection reaction, sirolimus can be used alone, but is generally combined with lower dose of cyclosporine/tacrolimus and/or coicosteroids and mycophenolate mofetil. It is paicularly suitable for patients developing renal toxicity with cyclosporine.( Sirolimus is non nephrotoxic). 2)sirolimus coated stents are being used to reduce the incidence of coronary aery restenosis, by inhibiting endothelial proliferation at the site. Adverse effects:- Significantly, sirolimus is not nephrotoxic, but it can suppress bone marrow, mainly causing thrombocytopenia. Rise in serum lipids is common. Other adverse effects are diarrhoea, liver damage and pneumonitis. Ref:- kd tripathi; pg num:-882

Ans. (c) Stapedial otosclerosisRef: Logan Turners ENT 11th Ed; Page No-464Otosclerosis* Most commonly seen in third decade, i.e. 20-30 years of age.* Most commonly seen in females, with a ratio of 2:1.* It is most commonly seen in white peoples.* The most common site origin of otosclerosis is fissula ante fenestrum.* It is aggravated by any hormonal change, be it pregnancy or menopause.* It is an autosomal dominant disorder and positive family history.* Clinical features:# Patients presents with bilateral progressive conductive hearing loss (70-85%).# Otosclerosis is the most common cause of bilateral progressive conductive hearing loss in adults.# This patient gives the typical history of haring better in noisy surroundings, which is known as Paracusis willisii phenomenon. This is because the speaker raises his voice in noisy surroundings which now cross the hearings threshold of the patient.# Less commonly tinnitus can also occur in otosclerosis, particular in cochlear otosclerosis and active otosclerosis.# Sometimes otosclerosis is associated with Osteogenesis imperfecta and blue sclera, when it constitutes van dar Hoeve syndrome.* Investigation:# Tympanic membrane appears pearly white (normal) in 90% patients; it is called as mature otosclerosis.# 10% cases of otosclerosis are active. In these the active division is taking place on the medial wall of middle ear leading to increase vascularity. This appears pinkish through the intact tympanic membrane leading to flamingo pink appears of TM also known as Schwartz sign.# Audiometric test:Tuning fork testFindingsRinne'sNegativeWeber'sLateralized to the worst earABCSame as examinerSchwabachLengthenedGelle'sNegative (i.e. change in the pressure of EAC does not produce ant y change in hearings as ossicular chain is already fixed.* Pure tone Audiometry:# The audiogram of the patients shows anA-B gap > 15dB (Suggestive of conductive hearing loss). Complete fixation of foot plate leads to the maximum conductive hearing loss of 60dB.# There is typical dip at 2000Hz in the bone conduction curve. This dip is because of fixation of footplate of stapes, the natural frequency of which 2000Hz. Hence its fixation fails to transit this frequency sound.# This dip is known as "Carhart's notch". This dip disappears after the mobilization of footplate and stapes during the management of otosclerosis.TreatmentActive casesMature cases* Sodium fluoride (NaF):# Inactive cases i.e. when Scwartze sign is present, medial medical management with sodium fluoride is done.# NaF accelerates the maturation of the focus by increasing osteoblastic and decreasing osteolytic activity.# It also inhibits the proteolytic enzymes that release cytotoxic chemicals to Cochlea.* Surgery: In mature otosclerosis when the foot plate is fixed and active division has stopped the treatment consists of mobilization of foot plate of stapes. The surgical procedure s are:-* Stapedectomy:# Here the whole of the stapes is removed and the oval window is then covered with a fascia graft and prosthesis is placed over the graft with other end of prosthesis attached to the long process of incus.# The change of perilymph fistula, SN hearing loss and vertigo is higher in stapedectomy as compared to stapedotomy. Hence it is not preferred nowadays.# It is contraindicated in chronic nephritis, RA, pregnancy and lactation.* Bisphosphonates have also been used as they inhibit bone resorption.* Stapedotomy:# This is a more conservative and better procedure where the incudostapedial joint is separated; the Stapedial tendon is cut and the suprastructure of stapes (head, neck, anterior and posterior crura) is removed leaving the foot plate behind.# The most common prosthesis is used here Teflon piston.* Postoperative Complication:# Conductive hair loss.# Perilymph fistula# Facial nerve palsyHow to rule out other options?Meniere's disease# It is also known as endolymphatic hydrops. It is frequently a unilateral condition and seen in more commonly in young females (20-40 years).# It is largely idiopathic.Clinical features* Vertigo: It is the first symptoms of Meniere's disease and it lasts for at least 20 minutes till a maximum of up to 24 hours. This sudden onset of vertigo of Meniere's disease associated with vagal symptoms, i.e. nausea, vomiting, abdominal cramping, diarrhoea and bradycardia.* SN hearing loss and tinnitus can be seen.Investigations* Rinne Test: Positive* Weber test: Towards the normal ear* ABC: Shortened* Schwabach: Shortened* Recruitment: Positive* SISIS:70-100% (because of recruitment)Management* Salt and water restrictions* Labyrinthine sedatives* Vasodilators* Meniett deviceVestibular neuronitis* This condition is characterized by acute onset vertigo, nystagmus and tinnitus with nausea and vomiting lasting for days to weeks.* This is most likely because of viral infection involving the vestibular nave.* The cochlear part is not involved, so the hearing remains normal.* The caloric test shows diminished response.* It is managed by labyrinthine sedatives.

Select the false statement about P. jiroveci?
|
It is seen in only immunocompromised individuals
|
Frequently associated with CMV
|
May be associated with pneumatocele
|
Diagnosed with sputum microscopy
| 1
|
multi
|
Ans. is 'b' i.e., Frequently associated with CMV Lets see each option one by one. Robbin's Option 'a' - See following statements of Topley's mycology; "Pneumocystis are found in low number in the lungs of mammalian hosts with intact immune system and in more abundance in homeotherms with compromised immune status". "A decrease in cell mediated immunity is the single most impoant risk factor for the development of pneumocystis pneumonia". So, P. jiroveci may be seen both in immunocompromised individuals and individuals with intact immune system, but it causes pneumonia only in immunocompromised individuals. Option 'b' - P.jirovecii may be associated with CMV infection but it is not usually associated with CMV infection. Option 'c' - P.jirovecii may be associated with penumatocele formation but pneumatoceles are not associated in all cases of P.jirovecii pneumonia. Option 'd' - Option 'c' is paially correct. - Usually the diagnosis of pneumocystis pneumonia is confirmed by histopathologic staining of BAL fluid collected by bronchoscopy, but it can also be diagnosed by microscopic examination of induced sputum.

Sperm is the male reproductive cell in the sexual reproduction. Capacitation is the penultimate step in the maturation of mammalian spermatozoa and is required to render them competent to feilize an oocyte. This step is a biochemical event; the sperm moves normally and looks mature prior to capacitation. In vivo, this step typically occurs after ejaculation, in the female reproductive tract.

• Around 4-6 weeks of antibiotic therapy is used to avert chronic bacterial prostatitis.
Chronic Bacterial Prostatitis
• Due to persistent bacterial infection of prostate
• Insidious in onset, characterized by relapsing or recurrent UTI caused by persistence of pathogen in prostatic fluid despite of antibiotic therapy
• Diagnosis is made by microscopic examination and culture of prostatic expressate and culture of urine obtained before and after prostatic massage.
• Treated by chronic antibiotic suppression (3–4 months)
Prostatic Abscess
• Most cases result from complications of acute bacterial prostatitis
• Fluctuation is a very late sign
• Predisposing factors: Diabetes, renal insufficiency, immunosuppression, urethral instrumentation, chronic indwelling catheter
• Diagnosis: TRUS or pelvic CT scan is crucial for diagnosis and treatment

Cardiolipin Is a Major Lipid of Mitochondrial Membranes
Phosphatidic acid is a precursor of phosphatidylglycerol, which in turn gives rise to cardiolipin. This phospholipid is found only in mitochondria and is essential for the mitochondrial function. Decreased cardiolipin levels or alterations in its structure or metabolism cause mitochondrial dysfunction in aging and in pathological conditions including heart failure, hypothyroidism, and Barth syndrome (cardioskeletal myopathy).

Brain imaging Imaging tests can help diagnose hydrocephalus and identify underlying causes of the symptoms. These tests may include: Ultrasound. Ultrasound imaging, which uses high-frequency sound waves to produce images, is often used for an initial assessment for infants because it&;s a relatively simple, low-risk procedure. The ultrasound device is placed over the soft spot (fontanel) on the top of a baby&;s head. Ultrasound may also detect hydrocephalus prior to bih when the procedure is used during routine prenatal examinations. Magnetic resonance imaging (MRI) uses radio waves and a magnetic field to produce detailed 3D or cross-sectional images of the brain. This test is painless, but it is noisy and requires lying still. MRI scans can show enlarged ventricles caused by excess cerebrospinal fluid. They may also be used to identify underlying causes of hydrocephalus or other conditions contributing to the symptoms. Children may need mild sedation for some MRI scans. However, some hospitals use a very fast version of MRIthat generally doesn&;t require sedation. Computerized tomography (CT) scan is a specialized X-ray technology that can produce cross-sectional views of the brain. Scanning is painless and quick. But this test also requires lying still, so a child usually receives a mild sedative. Drawbacks to CT scanning include less detailed images than an MRI, and exposure to a small amount of radiation. CT scans for hydrocephalus are usually used only for emergency exams. Reference: GHAI Essential pediatrics, 8th edition

|

|

| 1
|
multi
|
Ans. is 'b' ie. IVC involvement indicates inoperability A renal cell carcinoma that has spread to renal vein, IVC or even upto the thorax (hea) is operable. A preop biopsy is not necessary as a RCC is the most common malignant neoplasm of kidney (90 - 95%) and any solid renal mass is considered to be RCC until unless proved otherwise. A chest x-ray should be done to rule out pulmonary metastasis as it will make the Ca of stage IV with worst prognosis and also decide the tit plan. Radiotherapy, Chemotherapy or Hormonal therapy have little role in RCC t/t. More about Renal cell carcinoma Its the MC malignant neoplasm of kidney (90 - 95%) MC site of origin is prox. convoluted tubules RCC originates in the coex and tends to grow out into perinephric tissue. Usually situated at poles (commonly at upper pole) Male female ratio is 2 : 1 Age - 5th to 6th decade Risk factors: i) Cigarette smoking ii) Obesity iii) Polycystic kidney ds iv) Tuberous sclerosis v) Von-Hippel lindau syndorme (Cerebellar hemangioblastoma, retinal angiomatosis and b/1 renal cell Ca) Histologically RCC is an adenocarcinoma. It has been reclassified into subtypes of which Clear Cell Ca is the MC type. Classical triad of RCC consists of Hematuria Flank pain Palpable flank mass Earliest and MC presenting feature is hematuria. Paraneoplastic syndormes i) Fever of unknown origin ii) Anemia iii) Erythrocytosis (d/t secretion of erythropoietin by RCC) (but anemia is a more common finding) iv) Hypeension v) Abnormal liver function (Stauffers syndrome ie non metastatic hepatic dysfunction) vi) Hypercalcemia vii) Neuromyopathy viii) Amyloidosis ix) Increased ESR (MC paraneoplastic syndrome) x) Dysfibrogenemia xi) Cushing's syndrome xii) Galactorrhoea xiii) Feminization and masculanization MC route of metastasis is hematogenous MC site of distant metastasis is lung (canon ball secondaries, secondaries may be pulsatile) Inv. of choice --> CT scan.

So mechanical stimulation of ear canal while cleansing it cause stimulation of this nerve branch of vagus nerve and may induce cough. The auricular branch of vagus nerve passes through the mastoid canaliculus and through a space between the mastoid process and the tympanic pa of the temporal bone to the external ear and external auditory canal. The ear canal receives sensory fibers from the glossopharyngeal nerve through its communicating branch with the vagus nerve.

ESSENTIALS of medical PHARMOCOLOGY SEVENTH EDITION KD TRIPATHI Page :636,637 Impoant statins are :lovastatin Simvastain, pravastatin, rosuvastatin etc Rosuvastatin This is the latest and the most potent statin (10 mg rosuvastatin :::::. 20 mg atorvastatin), with a plasma tlh. of 18-24 hours. Greater LDL-CH reduction can be obtained in severe hypercholesterolaemia; paly due to its longer persistence in the plasma. In patients with raised TG levels, rosuvastatin raises HDL-CH by 15--20% (greater rise than other statins). Dose: Sta with 5 mg OD, increase if needed upto 20 mg/ day, (max 40 mg/ day) ROSUV AS, ROSYN 5, 10, 20 mg tabs. Adverse effects All statins are remarkably well tolerated; overall incidence of side effects not differing from placebo. Notable side effects are: * Headache, nausea, bowel upset, rashes. * Sleep disturbances (probably more with lipophilic drugs). * Rise in serum transaminase can occur, but liver damage is rare. * Muscle tenderness and rise in CPK levels occurs infrequently. Myopathy is the only serious reaction, but is rare ( < 1 per 1000). Few fatalities due to rhabdomyolysis are on record. Myopathy is more common when nicotinic acid/ gemfibrozil or CYP3A4 inhibitor- ketoconazole I erythromycin/ cyclosporine I HIV protease inhibitor is given concurrently. Gemfibrozil inhibits the hepatic uptake of statins by the organic anion traspoer OATP2.it must not be given to pregnant ladies. Uesd in primary hyperlipipidemias.

Ans. is 'b' i.e., LactuloseDietary fibres (Review) Dietary fibre consists of unabsorbable cell wall and other consititutents of vegetable food like celluloseQ, lignin, hemicellulosee, gums, pectinsdeg, aliginates and other polysaccharides.In herbivorous animals, intestinal microoganism breakdown these polysaccharides into acetate, propionate and butyrate.These polysaccharides contain 13-glycosidic linkages.Therefore, they cannot be digested by a-amylase present in human saliva and pancreatic juice because a-amylase breaks a-glycosidic bond (especially 1-4 a linkage).So, dietary fibers are not digested or hydrolyzed but are fermented by colonic bacteria except for lignin, which is neither digested nor fermented by intestinal microorganismsdeg.Dietary fibre absorbes water in the intestine, swells, increase bulk of stool by increasing water content of faeces and soften it, decreases transit time by facilitating colonic tansit."The presence of fibre shoens the transit timese and increases the stool bulk".Dietary fibre is of two types : -Soluble fibree : - These are pectin, aliginates, and gums. These absorb upto 15 times its weight in water as it moves through GIT, producing softer stools. Its good sources are oat, flaxseeds, peas, beans, apple, citrus fruits, carrots, bareley and psyllium.Insoluble fibredeg : - These are cellulose, hemicellulose and lignin. These promote movement of material through digestive system and increases stool bulk. Its good sources are wheat flour, wheat bran, nuts and vegetables.

Ans. is 'a' i.e., Nasopharyngeal carcinoma o Among the given options only nasopharyngeal carcinoma is a common cause of cervical nodes in 70 years male,o Information in this question :i) Cervical adenopathy (Neck node) Most common presentation of nasopharyngeal carcinoma.ii) Type B tympanogram Indicates serous otitis media, which may be a complication of nasopharyngeal carcinoma due to eustachian tube blockade.o Thus, among the given options, nasopharyngeal carcinoma is the answer of choice.Clinical features of nasophary ngeal carcinomao Symptomatology of nasopharyngeal carcinoma is divided into five main groupsNasal symptomsNasal obstruction, nasal discharge, denasal speech (rhinolalia clausa), episiaxis.Otologic symptomsOtologic symptoms are due to obstruction of eustachian tube.This results in serous or suppurative otitis media. Which causes conductive deafness.Presence of unilateral serous otitis media in adult should raise the suspicion of nasopharyngeal carcinoma.Tinnitus and dizziness may occur.OphthalomoneuroLogical symptomsThese symptoms occur due to spread of tumor to the surrounding regions.Squint and diplopia due to involvement of VP cranial nerve.Ophthalmoplagia due to involvement of IIIrd. IVth &. VIth cranial nerve.Facial pain & reduced corneal sensations due to Vth nerve involvementExophthalmos and blindness due to direct extension into the orbit.Jugular foramen syndrome (IXth, Xth, XIth cranial nerve involvementj due to pressure by enlarged lateral retropharyngeal lymph nodes.Cranial nerve XIth involvement due to extension of growth to hypoglossal canal.Horner's syndrome due involvement of cervical sympathetic chain.Neckmass:-Itisthemnstcommonpresentation(60-90%)Due to cervical lymphadenopathy.Distant metastasisInvolve bone, lung, liver and other sites.

Vi antigen is present in all except S.paratyphi A. Vi Antigen: It is the surface polysaccharide envelope or capsular antigen covering the O antigen. Expressed in :- S.typhi, S. paratyphi C, S. dublin and some strains of Citrobacter freundii. When Vi antigen is present, it renders the bacilli inagglutinable with the O antiserum. Poorly immunogenic and antibody titres are low, not helpful in diagnosis , hence not employed in the Widal test. Complete absence of the Vi antibody in a proven case of typhoid fever- Poor prognosis. Note: Vi Antibodies are not seen in normal population.

Ans. is 'b' i.e., CBC,reti count with peripheral smear In above question, if child is stable, then no need to give blood transfusion. Before staing Iron, we have to rule out types of anemia as Iron is indicated only in nutritioral anemia. Hb ele ctrophoresis is indicated if there is featuer of hemolytic anemia (thalassemia) so over all our next step is complete hemogram with manual peripheral smear examination. (obtion b).

Ans. B. S2 S3 S4 The pudendal nerve (Root Value S2 S3 S4 ) is the main nerve of the perineum. It carries sensation from the external genitalia of both sexes and the skin around the anus and perineum, as well the motor supply to various pelvic muscles, including the male or female external urethral sphincter and the external anal sphincter. If damaged, most commonly by childbirth, lesions may cause sensory loss or fecal incontinence.
