A 1-year-old boy presents with a delay in motor development. Progressive muscle weakness and blindness ensue, and the patient dies within a year. The brain at autopsy shows swollen neurons that contain numerous lysosomes filled with lipid. Which of the following is the most likely diagnosis? | Tay-Sachs disease is a lethal, autosomal recessive disorder caused by an inborn deficiency of hexosaminidase A, which permits the accumulation of ganglioside GM1 in CNS neurons. The disease is fatal in infancy and early childhood. Retinal involvement increases macular transparency and is responsible for a cherry-red spot in the macula. On histologic examination, lipid droplets are seen in the cytoplasm of distended nerve cells of the CNS and peripheral nervous system. Electron microscopy reveals the lipid within lysosomes in the form of whorled "myelin figures." Swollen neurons that exhibit marked vacuolization of the perikaryon and contain lysosomes filled with lipid can also occur in other lipid-storage diseases (e.g., Gaucher disease, Niemann-Pick disease).

R-factor in bacteria is transferred by | Conjugation
Bacterial conjugation is the transfer of genetic material between bacteria through direct cell to cell contact or through a bridge- like the connection between two cells.
Conjugation is a process whereby a donor (male) bacterium makes physical contact with a recipient (female) bacterium.
Donor status is determined by the presence of plasmid.
This plasmid codes for specialized fimbria (sex pilus) and for self-transfer.
Sex pilus (conjugation tube) helps in transfer of genetic material from male bacterium to female bacterium.
The plasmid is known as transfer factor (sex factor or fertility factor).
The plasmid may be R factory which codes for transferrable multiple drug resistance.
The DNA of the plasmid replicates during transfer so that each bacterium receives a copy → Recipient becomes a donor and the donor retains its donor status. | 3 | Transduction | Transformation | Conjugation | Vertical transmission | Microbiology | null | 69f8092f-1fd4-489f-818f-72c1bd562463 | single |

An 18 year old male patient presented to the clinic with pain and swelling in the lower jaw. Intraoral examination

It may be congenital or traumatic in origin and may be difficult to differentiate from VM. The usual complaint of a patient with a VM or CH is of a slow-growing asymmetry of the jaw or localized gingival bleeding. Numbness and tenderness or pain may also be described.

Maximum FiO2 which can be given through a nasal oxygen catheter:- | A nasal cannula is generally used wherever small amounts of supplemental oxygen are required, without rigid control of respiration, such as in oxygen therapy. Most cannulae can only provide oxygen at low flow rates--up to 5 litres per minute (L/min)--delivering an oxygen concentration of 28-44%. Rates above 5 L/min can result in discomfo to the patient, drying of the nasal passages, and possibly nose bleeds (epistaxis). Also with flow rates above 6 L/min, the laminar flow becomes turbulent and the oxygen therapy being delivered is only as effective as delivering 5-6 L/min. The nasal cannula is often used in elderly patients or patients who can benefit from oxygen therapy but do not require it to self respirate. These patients do not need oxygen to the degree of wearing a non-rebreather mask. It is especially useful in those patients where vasoconstriction could negatively impact their condition, such as those suffering from strokes. | 4 | 1 | 0.6 | 0.2 | 0.44 | Anaesthesia | Anesthesia Circuit | 8fe8bc4d-d411-4281-98fa-f74eaf59212a | single |

The most accurate diagnostic test for Zollinger-Ellison syndrome (ZES) is | -All patients with gastrinoma have an elevated gastrin level, and hypergastrinemia in the presence of elevated basal acid output (BAO) strongly suggests gastrinoma. -Patients with gastrinoma usually have a BAO >15 mEq/h or >5 mEq/h if they have had a previous procedure for peptic ulcer. -Acid secretory medications should be held for several days before gastrin measurement, because acid suppression may falsely elevate gastrin levels. 1). The diagnosis of Zollinger-Ellison syndrome (ZES) is confirmed by the secretin stimulation test. An intravenous (IV) bolus of secretin (2 U/kg) is given and gastrin levels are checked before and after injection. - An increase in serum gastrin of 200 pg/mL or greater suggests the presence of gastrinoma. Patients with gastrinoma should have serum calcium and parathyroid hormone levels determined to rule out multiple endocrine neoplasia type 1 (MEN1) and, if present, parathyroidectomy should be considered before resection of gastrinoma. | 4 | Fasting serum gastrin | Computed tomography (CT) scan | Endoscopy | Secretin stimulation test | Surgery | Stomach & Duodenum | 977cfd21-baf1-4a64-a125-378d92fbdafb | single |

Preferred fluoroquinolone against m. leprae is - | Ans. is 'a' i.e., Ofloxacin Drugs acting on M. leprae* Established agents used to treat leprosy include dapsone (50-100 mg/d), clofazimine (50-100 mg/d, 100 mg three times weekly, or 300 mg monthly), and rifampin (600 mg daily or monthly. Of these drugs, only rifampin is bactericidal.* The sulfones (folate antagonists), the foremost of which is dapsone, were the first antimicrobial agents found to be effective for the treatment of leprosy and are still the mainstay of therapy.* Other antimicrobial agents active against M. leprae in animal models and at the usual daily doses used in clinical trials include ethionamide/prothionamide; the aminoglycosides streptomycin, kanamycin, and amikacin (but not gentamicin or tobramycin); minocycline; clarithromycin; and several fluoroquinolones, particularly preferred is ofloxacin.* Next to rifampin, minocycline, clarithromycin, and ofloxacin appear to be most bactericidal for M. leprae, but these drugs have not been used extensively in leprosy control programs. Most recently, rifapentine and moxifloxacin have been found to be especially potent against M. leprae in mice. In a clinical trial in lepromatous leprosy, moxifloxacin was profoundly bactericidal, matched in potency only by rifampin. | 1 | Ofloxacin | Pefloxacin | Ciprofloxacin | Moxifloxacin | Pharmacology | Anti Microbial | c939bbeb-af27-43ec-8ad1-d7f70f5543eb | single |

A 70-year-old man comes to casualty with urinary retention and back pain. Which investigation should be performed - | pt. is suspected to have Ca Prostate as Prostatic Ca is the most common malignant tumor in men over 65 yrs. of age. Symptoms of Bladder outlet obstruction and back pains (due to bony metastasis in the pelvis & lumbar veebra) indicate towards prostate Ca. Serum acid phosphates is a tumor marker of prostate Ca. But now serum acid phosphates assay has been superseded by PSA assay (Prostate specific antigen). Prostate-specific antigen It is a glycoprotein produced only in the prostatic cells (both benign & malignant). It facilitates liquefaction of semen. It is neither sensitive nor specific for early prostate carcinoma (it is prostate specific and not prostate cancer specific), neveheless it gives some help in making a diagnosis. Normal serum level - less than 4 mg/ml 4 - 10 mg/ml - this range is common for both BHP and Ca. More than 10 mg/ml - approx 75% will have cancer. Since PSA is not specific for Ca, PSA Velocity & PSA density is used to detect Prostate cancer. PSA velocity is the rate of change in PSA levels over time and is expressed most commonly as the PSA doubling time. For men with a PSA above 4, PSA velocity of more than .75 mg/ml year is suggestive of Ca. While for those with lower PSA levels, rates above 0.5 mg/ml, per year should be used to advise biopsy. PSA density is calculated by dividing the serum PSA by the estimated prostate weight (measured by TRUS). It was developed to correct for the contribution of BPH to the total PSA level. Values < 0.10 are consistent with BPH. > 0.15 suggest cancer Ref : Bailey & Love 25/e p1356 | 1 | Serum acid phosphatase | Serum Calcium | Serum alkaline phosphatase | Serum electrophoresis | Anatomy | Urology | d73190cf-3f68-4d02-a7f5-0d6fac8cdcdb | single |
