The brain at autopsy shows swollen neurons that contain numerous lysosomes filled with lipid. Which of the following is the most likely diagnosis?",AL amyloidosis,Hurler syndrome,Phenylketonuria,Tay-Sachs disease,3,single,"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). The other diseases do not produce such neuronal changes.Diagnosis: Tay-Sachs disease",Pathology,Central Nervous System

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.",Microbiology,

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.

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",Anatomy,Urology

This allow time for DNA repair.b) DNA repair: p-53 also helps in DNA repair directly by inducing transcription of GADD 45 (growth arrest and DNA damage). GADD 45 encodes a protein that is involved in DNA repair.* If DNA damage is repaired successfully, p53 activate MDM-3 and this MDM-3 induce degradation of p-53 - Relieve in cell cycle block. If DNA damage cannot be successfully repaired, p53 induces apoptosis by inducing the activation of apoptosis inducing gene BAX. So p-53 prevents replication of cell with defective DNA - p53 functions as a critical gatekeeper against formation of cancer.

It allows the fixed appliance to be removed somewhat more quickly than otherwise would have been the case (i.e., some finishing that could have been done with the final archwires can be left to the positioner)
It serves not only to reposition the teeth but also to massage the gingiva, which is almost always at least slightly inflamed and swollen after comprehensive orthodontic treatment. The gingival stimulation provided by a positioner is an excellent way to promote a rapid return to normal gingival contours.

As a general rule, a tooth positioner in a cooperative patient will produce any changes it is capable of within 2-3 weeks. Final (post-treatment) records and retainer impressions can be taken 2 or 3 weeks after the positioner is placed. Beyond that time, if the positioner is continued, it is serving as a retainer rather than a finishing device-and positioners, as a rule, are not good retainers.

Use of high inspiratory flow rate can minimize end inspiratory lung volume and intrinsic PEEP, but it can cause higher peak airway pressures. Volume cycled assist control mode of ventilation is the most commonly used mode of ventilation. Volume targeted modes deliver a preset volume unless a specified circuit pressure limit is exceeded. Its major advantages are capacity to deliver unvarying tidal volumes, flexibility of flow and volume adjustments, and power to ventilate difficult patients. Disadvantages of this type of ventilation are: Unless the airway is well sealed volume cycled modes cannot ventilate effectively and consistently. After the flow rate and profile are set the inflation time of machine is set and remains unresponsive to patients native cycling rythm and flow demands.

Xerophthalmia caused by a severe vitamin A deficiency is described by pathologic dryness of the conjunctiva and * cornea. The conjunctiva becomes dry, thick and wrinkled. If untreated, it can lead to corneal ulceration and ultimately to blindness as a result of corneal damage. Xerophthalmia is a term that usually implies a destructive dryness of the conjunctival epithelium due to dietary vitamin A deficiency -- a rare condition in developed countries, but still causing much damage in developing countries. Other forms of dry eye are associated with aging, poor lid closure, scarring from previous injury, or autoimmune diseases such as rheumatoid ahritis and SjOgren's syndrome, and these can all cause chronic conjunctivitis. Radioiodine therapy can also induce xerophthalmia, often transiently Xerophthalmia from hypovitaminosis A is specifically due to lack of the hormone-like vitamin A metabolite retinoic acid Treatment can occur in two ways: treating symptoms and treating the deficiency. Treatment of symptoms usually includes use of aificial tears in the form of eye drops, increasing the humidity of the environment with humidifiers, and wearing wrap around glasses when outdoors. Treatment of the deficiency can be accomplished with a Vitamin A or multivitamin supplement or by eating foods rich in Vitamin A. Treatment with supplements and/or diet can be successful until the disease progresses as far as corneal ulceration, at which point only an extreme surgery can offer a chance of returning sight.",Social & Preventive Medicine,
