Nbme 13 Block 2 Answers Free Of BileBringing more sodium into the cell reduces its water potential, causing water to re-enter the cell from the lumen by osmosis. The glucose in the oral rehydration solution ensures that the protein will bring as much sodium as possible into the cell. This provides energy and helps the sodium–glucose cotransporter protein, which absorbs sodium into the cell much better if glucose is also present. Tags:And motor activity are carried by corticospinal tractThis patient has decreased bile absorption due to jejunoileal bypass as blie is absorbed from ileum,a decrease in bile absorption by turn will lead to decrease fat and fat soluble vitamins absorption (K,E,D,A) ,hence fecal fat is increased and fat soluble deficiency will developBcl-2 is antiapoptotic , so when overexpressed , it will decrease cell deathHistory of severe cramping pain in right flank that radiates to groin + pain not releived by position > stoneProphylaxis of stone formation is by drinking large amount of water in order not to let solutes concentrate and form stonesAlthough calcium stones are the most common type kidney stones ,decreasing calcium in diet is not helpful as most cases of kidney stones occur in people with normal calcium level (normocalcemia & hypercalciuria) , and calcium absorption is regulated by vit dChancre: charachterized by mononuclear cell infiltrate dominated by plasma cells with scattered histiocytes also obliterative endarteritis with thickened small vessels due to proliferation of endothelial cells and fibroblastsCondyloma lata: resembles condyloma acuminatum, and charachterized by prominent epidermal hyperplasia, more edema, chronic inflammatory infiltrate, but less keratinization, minimal if any koilocytosisImportant key to know that headache is the most initial symptom on CO poisoningIn addition to being in a closed cabin in a truck raises suspicion of poisoning with Vehicle exhaustCO poisoning is treated with 100% O2 + hyperbaric O2- failure to form or early destruction of extrahepatic biliary tree- leads to biliary obstruction within first three months of life- normal at birth and then destructed by immune mediated or viral induced- presents with jaundice (conjugated bilirubin) and progress to cirrhosisThe cardiac phonogram shows a holosystolyc murmurThe only choice which causes this finding is mitral regurgitationVomiting associated with cancer chemotherapy is usually treated or prevented with ondansetron as first therapyMetochlopramide is commonly used in diabetic and postsurgery gastroparesisThe main function of ATll is vasoconstriction and constrict the efferent arteriole leading to increase GFR with compensatory water and Na reabsorption at the distal collecting tubulesThe ACE inhibitor block the conversion of ATl to ATIl so it will block the main function which is the vasoconstriction of the efferent arteriolesThis case describes xeroderma pigmentosa , in which there is defective nucleotide excision repair resulting in pyrimidine dimers that are formed due to exposure to UV raysKeep in mind that xeroderma pigmentosa can cause both basal cell carcinoma and squamous cell carcinomaBy definition, in situ carcinoma means superficial to basement membraneIf it penetrated basement membrane and reached muscle layer,stroma or venules, it is called invasive carcinomaCertainly you know that metastatic carcinoma is not carcinoma in situ □For the new born to be diagnosed with HIV, PCR is to be done for viral DNAIt is a new concept that you should know,but even if you do not know the answer ,you can answer correctly:By exclusion,central thermoregulation is mediated by hypothalamus,skin graft and burns has no rule with this.Injured and inflammed skin may cause release of mediators that act as endogenous pyrogens but this would be acutely not continuous for years.There is no large difference between normal skin and grafted or scar skin in sensitivity to heat or sunlight to the degreee that cause hyperthermiaIt is very very very high yield to know everything about metformin as it is highly used nowadaysIt inhibits hepatic gluconeogenesis ,it also lead to inhibition of mitochondrial isoform of glycerol-3-phosphate dehydrogenase & complex 1 in electron transport chain in liver.If you decided to know one single most important thing about metformin , it would be a side effect of LACTIC ACIDOSIS !!!!!!!!!!Rifampin inhibits DNA dependent RNA polymerase in prokaryotes (this enzyme makes all three types of RNA in prokaryotes unlike eukaryotes that have 3 types of RNA polymerase)Bilateral crackles on auscultation > pulmonary edema > left side heart failure (most commonly in USMLE)Pitting ankle edema > right side heart failureLow blood pressure + peripheral cyanosis with these clues indicates systolic heart failure (diagnosis is supported by pre-eisting hypertension)In systolic heart failure > decrease cardiac output (CO)Right sided heart failure > increased systemic venous pressure (SVP)After circumflex artery angioplasty, blood will increase to regions supplied by it ,which will be left ventricleNOTE that this patient has a right dominant heart circulation so posterior descending artery arise from right coronary artery, if it was left dominant or codominant,circumflex artery would share in supply of PDA and hence regions supplied by PDAVegetarian for 12 years + macrocytic anemia + neurological manifestations > vit B 12 deficiency6-week-old + projectile vomiting - vomitus free of bile > pyloric stenosisYou should know that pyloric stenosis is not present at birth but develops later (within 2 weeks)Congenital megacolon presents in first 2 days of life by failure to pass meconiumArea postrema is found in medulla and is responsible of vomitingNote that it is one of areas that are not protected by blood brain barrier so it is easily stimulated to produce vomiting by different toxins circulating in the blood.It is also the target of some antiemetic drugsQuestion stem describes manifestations of parkinsonism diseaseIn parkinsonism: the lesion is in substantia nigra which is found in midbrain as indicated by the arrowTubular absorption is mostly by active transport using ATP , so high amount of oxygen is used (especially proximal convoluted tubules and thick ascending limb of loop of henle)While glomerular filtration is a passive processORS, Oral rehydration solution also contains glucose.
