In irreversible pulpitis, pain in which of the following sites is most likely to radiate to the ear?
|
Mandibular molar. The perception of pain in one part of the body that is distant from the actual source of the pain is known as referred pain. Teeth may refer pain to other areas of the head and neck. Referred pain is usually provoked by stimulation of pulpal C-fibers, the slow conducting nerves that, when stimulated, cause an intense, dull, slow pain. It always radiates to the ipsilateral side. Posterior teeth may refer pain to the opposite arch or periauricular area. Mandibular posterior teeth tend to transmit referred pain to the periauricular area more often than do the maxillary posterior teeth.

Nerve supply to musculature of urinary bladder is ?
|
Ans. is 'c' i.e., BothParasympathetic supply is motor to detrusor muscle and inhibitory to sphinchter vesicae. Sympathetic supply is motor to sphincter vesicae and inhibitory to detrusor muscle.Nerve supply of bladderBladder is supplied by both sympathetic and parasympathetic fibers.Parasympathetic : Preganglionic fibers arise from S2 to S4 cord segments, pass pelvic splanchnic nerves. After relay in ganglion cells in pelvic plexus (inferior hypogastric plexus) and in bladder wall, postganglionic fibers supply detrusor muscle. Contraction of detrusor muscle is mediated by cholinergic muscarinic receptors(M3).Preganglionic parasympathetic neurons at S2,and S4cord segments innervating bladder form sacral micturition center.Sympathetic : Preganglionoic fibers arise from lateral horn cells of T1-L2 cord segments and pass lower lumbar splanchnic nerves, superior hypogastric plexus (presacral nerve of Latarjet) to reach inferior hypogastric (pelvic) plexus. After relay in pelvic ganglia, postganglionic sympathetic fibers (i) stimulate sphincter vesicae (internal urethral sphincter) a, adrenoceptors and (ii) cause relaxation of detrusor muscle 132 adrenoceptors. It can also inhibit presynaptically the parasympathetic ganglia a, adrenoceptorsVisceral afferents : (1) pain fibers from bladder pass through both parasympathetic and sympathetic pathway and enter TH-L2 and S2-S4 cord segments, hence referred pain is felt in lower pa of anterior abdominal wall (hypogastrium), upper pa of front of thigh, scrotum or labium majus, penis or clitoris, and perineum. Centrally, spinothalmic pathway conducts pain impulses from bladder.Stretch afferents : arising from stretch receptors in the bladder wall pass pelvic splanchnic nerves, enter S2, S3 and S4 cord segments and establish reflex connections with sacral micturition center, which innervates detrusor.So afferent and efferent limb of this micturition reflex is formed by pelvic splanchnic nerves.Sacral mictruition center and the micturition reflex are controlled by facilitatory and inhibitory centers located in pons and paracentral lobule of frontal lobe of cerebum.

|
(30-300 mg/d) (249-H) (1077-8-CMDT-09)(272, 1533, 1792-H17th)* Currently, ultrasensitive dipsticks are available to measure microalbuminuria (30 to 300 mg/d), an early marker of glomerular disease that has been shown to predict glomerular injury in early diabetic nephropathy (249-H)* Normal subjects excrete less than 15 mg/min during overnight urine collections; values of 20 mg/min during or higher are considered to represent abnormal microalbuminuria. In the early morning spot urine, a ratio of albumin (mg/L) to creatinine (mg/L) of < 30 mg/mg creatinine is normal and a ratio of 30-300 mg/mg creatinine suggests abnormal microalbuminuria.* Increased microalbuminuria correlates with increased levels of blood pressure and increased LDL cholesterol, and this may explain why increased proteinuria in diabetic patients is associated with an increase in cardiovascular deaths even in the absence of renal failure (1186-CMDT-05)

This is called Breur Lockhgard reflex.The most common cause of asthmatic attack during surgery is inadequate depth of anesthesia. What to be done during an asthmatic attack during anaesthesia?First, deepen die level of anesthesia.Increase Fi02.Patient is under anesthesia and undergoing surgery, so medical interventions such as beta agonist administration is not the first choice of treatment.When the level of anaesthesia is light, the patient may develop bucking, straining or coughing as a result of endotracheal tube in the trachea and then hronchospasm.Other Methods:IV Ketamine: Increases BP, deepens anaesthesia, causes bronchodilation.Beta agoinst nebulization: Causes bronchodilation.

Sciatic nerve injury as a result of surgery occurs in 2% to 6% of patients and is more often associated with posterior fracture patterns treated through the Kocher-Langenbeck and extensile exposures." - Campbell's operative ohopaedics 11/e Chapter 53 -Fractures of Acetabulum and Pelvis Despite searching extensively I could not get any relevant text explaining the rest of options. Here's some material on Kocher-Langenbeck approach, which might be useful.

The following fractures may be accessed through a Kocher-Langenbeck approach: - Transverse fractures through the acetabular roof. However, a lateral approach will often be preferred. - T-shaped fractures, especially if the anterior column is not excessively displaced. Where difficulties are encountered, a large lateral approach is often preferred . - Low both-column fractures that do not involve the iliac wing .

Sternberg's canal (persistent lateral craniopharyngeal canal)
Originally described by Sternberg in 1888 and was reported to be constantly present in children at the age of 3-4 years. He described an incidence of 4% in adults. (Persistent vestiges have been reported in upto 30% of adults).
It is caused by incomplete fusion of greater wing of sphenoid with presphenoid at a point where primordial sphenoid portions fuse.
It lies anterior and medial to foramen rotadum in parasellar region in middle cranial fossa.
It can communicate with sphenoid sinus, pterygopalatine fossa, nasopharynx, or pass right through the bone to emerge at the base of the skull.
Clinically Sternberg's canal is important as it is clinically associated with:-
Infection to sphenoid sinus or cranial fossa.
Congenital intrasphenoid meningocele (& encephalocele).

Which of the following serum markers is most useful for monitoring the recurrence of tumor in this patient?
|
Most testicular neoplasms in the first 4 years of life are classified as yolk sac tumors. Microscopic examination of a yolk sac tumor shows interlacing strands of epithelial cells surrounded by loose connective stroma. The lobular arrangement of cells, surrounded by empty spaces, leads to the formation of glomeruloid structures referred to as Schiller-Duval bodies. Although yolk sac tumors are malignant, timely orchiectomy results in a 95% cure rate. These tumors produce a -fetoprotein, which can be used for monitoring the recurrence of disease following surgery Human chorionic gonadotropin (choice E) is secreted by choriocarcinoma.Diagnosis: Yolk sac tumor

The inheritance pattern of Familial hypercholesterolemia is
|
Mutations involving single genes follow one of three patterns of inheritance: autosomal dominant, autosomal recessive, or X-linked. Autosomal Dominant Inheritance Familial hypercholesterolemia Huntington disease Marfan syndrome Ehlers-Danlos syndrome Hereditary spherocytosis Neurofibromatosis, type 1 Adult polycystic kidney disease Familial Hypercholesterolemia Familial hypercholesterolemia is among the most common mendelian disorders; the frequency of the heterozygous condition is 1 in 500 in the general population. It is caused by a mutation in the LDLR gene that encodes the receptor for low-density lipoprotein (LDL), the form in which 70% of total plasma cholesterol is transpoed. A brief review of the synthesis and transpo of cholesterol follows. Normal Cholesterol Metabolism. Cholesterol may be derived from the diet or from endogenous synthesis. Dietary triglycerides and cholesterol are incorporated into chylomicrons in the intestinal mucosa, which drain by way of the gut lymphatics into the blood. These chylomicrons are hydrolyzed by an endothelial lipoprotein lipase in the capillaries of muscle and fat. The chylomicron remnants, rich in cholesterol, are then delivered to the liver. Some of the cholesterol enters the metabolic pool (to be described), and some is excreted as free cholesterol or bile acids into the biliary tract. The endogenous synthesis of cholesterol and LDL begins in the liver (Fig. 6-2). The first step in the synthesis of LDL is the secretion of triglyceride-rich very- low-density lipoprotein (VLDL) by the liver into the blood. In the capillaries of adipose tissue and muscle, the VLDL paicle undergoes lipolysis and is conveed to intermediate- density lipoprotein (IDL). In comparison with VLDL, the content of triglyceride is reduced and that of cholesteryl esters enriched in intermediate-density lipoprotein (IDL), but IDL retains on its surface two of the three VLDL- associated apolipoproteins B-100 and E. Fuher metabo- lism of IDL occurs along two pathways: Most of the IDL paicles are directly taken up by the liver through the LDL receptor described later; others are conveed to cholesterol- rich LDL by a fuher loss of triglycerides and apolipopro- tein E. In the liver cells, IDL is recycled to generate VLDL. Two thirds of the resultant LDL paicles are metabo- lized by the LDL receptor pathway, and the rest is metabo- lized by a receptor for oxidized LDL (scavenger receptor), to be described later. The LDL receptor binds to apolipo- proteins B-100 and E and thus is involved in the transpo of both LDL and IDL. Although the LDL receptors are widely distributed, approximately 75% are located on hepatocytes, so the liver plays an extremely impoant role in LDL metabolism. The first step in the receptor-mediated transpo of LDL involves binding to the cell surface receptor, followed by endocy- totic internalization inside so-called "clathrin-coated pits" (Fig. 6-3). Within the cell, the endocytic vesicles fuse with the lysosomes, and the LDL molecule is enzymatically degraded, resulting ultimately in the release of free cholesterol into the cytoplasm. The cholesterol not only is used by the cell for membrane synthesis but also takes pa in intracel- lular cholesterol homeostasis by a sophisticated system of feed- back control: * It suppresses cholesterol synthesis by inhibiting the activity of the enzyme 3-hydroxy-3-methylglutaryl- coenzyme A reductase (HMG-CoA reductase), which is the rate-limiting enzyme in the synthetic pathway. * It stimulates the formation of cholesterol esters for storage of excess cholesterol. * It downregulates the synthesis of cell surface LDL recep- tors, thus protecting cells from excessive accumulation of cholesterol. The transpo of LDL by the scavenger receptors, alluded to earlier, seems to take place in cells of the mononuclear- phagocyte system and possibly in other cells as well. Monocytes and macrophages have receptors for chemically modified (e.g., acetylated or oxidized) LDLs. The amount catabolized by this "scavenger receptor" pathway is directly related to the plasma cholesterol level. (Robbins Basic Pathology,9th edition,pg no. 219)

A 68 yr old man came with pain and swelling of right knee. Ahlbeck grade 2 osteoahritic changes were found on investigation. What is the fuher management:
|
D i.e. Total knee replacement - Ahlbeck grade 2 osteoahritis (i.e. complete or almost complete obliterated joint space) with symptoms of pain and swelling in a sedentary patient (>65 years of age) is managed by knee replacementQ - Old (65 yrs) age, long standing history of pain & swelling interfering activities of daily living and grade III radiological grade of OA indicate moderately severe OA and is best managed by Total knee ahroplasty. Although it must be remembered that TKA is done only after conservative treatment measures have been exhausted. And in this case we have presumed that conservative treatment must have been tried (b/o long course) & failed. - Because ahroscopic lavage (wash out) provides symptomatic improvements in patients with normal alignment, joint space >3mmQ, stable ligaments, unicompamental OA with relevant osteophytes at the site of symptom, loose bodies, minimal Fair bank lesions, meniscal flap tear, chondral fracture/flap and outerbridge I or II lesions. And patients with bi/tri compamental OA, malalignment, irrelevant osteophytes away from symptom site, diffuse chondrosis, degenerative meniscus, significant Fair bank lesion and outbridge III or IV are poor prognostic factors for ahroscopic debridement. So obliterated joint space rules out the possibility of conservative and ahroscopic treatments. - High tibial osteotomy is indicated in physiologically young (years) and active patients with unicompamental OA of tibiofemoral jointsQ.

Intra aerial injections of hyaluronic acid & steroid may be helpful in early minimal ahritis. Ahroscopic lavage (wash out) provides symptomatic improvements in patients with normal alignment, joint space >3mmQ, stable ligaments, unicompamental OA with relevant osteophytes at the site of symptom, loose bodies, minimal Fair bank lesions, meniscal flap tear, chondral fracture/flap and outerbridge I or II lesions. And patients with bi/tri compamental OA, malalignment, irrelevant osteophytes away from symptom site, diffuse chondrosis, degenerative meniscus, significant Fair bank lesion and outbridge III or IV are poor prognostic factors for ahroscopic debridement. Total (Tricompamental) Knee Replacement (TKR) : Indications - Primary indication of TKR is to relieve pain caused by severe ahritis with or without significant deformityQ. Radiological finding must correlate with clinical impression of knee ahritis. Patient who do not have complete cailage space loss before surgery tend to be less satisfied with their clinical result after TKR. - Severe pain from chondrocalcinosis & pseudogout in an elderly patient is an occasional indication of TKR in absence of complete cailage space loss. Severe patellofemoral ahritis in elderly may justify TKR because the expected outcome is better than that of patellectomy in these patients. - Osteonecrosis with subchondral collapse of femoral condyle. - Because knee replacement has a finite expected survival that is adversely affected by activity level, it generally is indicated in older patients with more sedentary life styles. It is preferable that patients undergoing TKA have a remaining normal life expectancy of between 20 & 30 years so that need for a repeat ahroplasty for a failed TKA will be minimal. It is clearly indicated in young patients who have limited function b/o systemic ahritis (eg rheumatoid ahritis) with multiple joint involvement. But the patient must understand the limitations of the procedure, be willing to modify life style to prolong the life of prosthesis and be willing to risk the lower success rate in a revision TKA. - Deformity can become the principle indication for TKR in patient with moderate ahritis & variable levels of pain when the progression of deformity begins to threaten the expected outcome of an anticipated TKR. This includes flexion contractures beyond 20deg and vurus/ valgus laxity. However, deformity without pain is not a suitable indication for surgery as it may be well tolerated by elderly. - Indications for leaving the patella unresurfaced are, a primary diagnosis of OA, satisfactory patellar cailage with no eburnated bone, congruent patello femoral tracking, a normal anatomical patellar shape and no evidence of crystalline or inflammatory ahropathy and lighter weight of patient. TKR: Contraindications - Absolute contraindications include recent or current knee infection; a remote source of ongoing infection; extensor mechanism discontinuity or severe dysfunction; recurvatum deformity secondary to muscular weakness; and presence of painless, well functioning knee ahrodesis. - Relative contraindications include fragile medical conditions, severe atherosclerotic disease of operative leg, skin conditions such as psoriasis within the operative field, venous stasis disease with recurrent cellulitis, neuropathic ahropathy, morbid obesity, recurrent UTI, and a h/o osteomyelitis in the proximity of knee.

An improved selective media to carry out the Lactobacillus Colony Test is:
|
Lactobacillus Colony Test:
The oldest and the most widely used microbiological method for assessing the caries activity is the Lactobacillus colony count. This method, measures the number of aciduric bacteria in a patient’s saliva by counting the number of colonies which appear on tomato peptone agar plates, a selective medium with pH 5.0, after inoculation of the patient’s saliva and incubation. An improved selective media with an acidic pH having high amounts of acetate, salts and lower surface tension that is highly selective for growth of Lactobacillus is the Rogosa’s medium. The colonies grown on media upon incubation reflect the number of aciduric flora in the patient’s saliva.
Note:
Hektoen enteric agar (HEK, HE or HEA) is a selective and differential agar primarily used to recover Salmonella and Shigella from patient specimens. HEA contains indicators of lactose fermentation and hydrogen sulfide production; as well as inhibitors to prevent the growth of Gram-positive bacteria. It is named after the Hektoen Institute in Chicago, where researchers developed the agar.
Mitis Salivarius Agar (MSA), a selective streptococcal medium with increased concentration of sucrose (20%) and 0.2 U bacitracin per ml to suppress the growth of most non S.mutans colonies. Agar plates are incubated at 37° C for 48 hours; 95% N2 - 5% CO2.

Fluconazole is an antifungal medication used for a number of fungal infections. This includes candidiasis, blastomycosis, coccidiodomycosis, cryptococcosis, histoplasmosis, dermatophytosis, and pityriasis versicolor. It is also used to prevent candidiasis in those who are at high risk such as following organ transplantation, low bih weight babies, and those with low blood neutrophil counts. It is given either by mouth or by injection into a vein. Fluconazole is a first-generation triazole antifungal medication. It differs from earlier azole antifungals (such as ketoconazole) in that its structure contains a triazole ring instead of an imidazole ring. While the imidazole antifungals are mainly used topically, fluconazole and ceain other triazole antifungals are preferred when systemic treatment is required because of their improved safety and predictable absorption when administered orally. Fluconazole's spectrum of activity includes most Candida species (but not Candida krusei or Candida glabrata), Cryptococcus neoformans, some dimorphic fungi, and dermatophytes, among others. Common uses include The treatment of non-systemic Candida infections of the vagina ("yeast infections"), throat, and mouth. Ceain systemic Candida infections in people with healthy immune systems, including infections of the bloodstream, kidney, or joints. Other antifungals are usually preferred when the infection is in the hea or central nervous system, and for the treatment of active infections in people with weak immune systems. The prevention of Candida infections in people with weak immune systems, such as those neutropenic due to cancer chemotherapy, those with advanced HIV infections, transplant patients, and premature infants.

Regarding campylobacterium jejuni not true is ?
|
Human is the only reservoir "Campylobacter jejuni is a common cause of bacterial gastroenteritis in most pas of the world". Reservoir The bacterium has a broad host range and has been isolated from a range of sources including surface and ground waters, domestic and wild mammals, insects and wild birds. The most prominent source of human infection is consumption of chicken meat (poultry) either directly or through cross-contamination with other food items. The intestines of poultry are easily colonized with campylobacter jejuni. Day old chicks can be colonized with as few as 35 organisms. Pathogenesis :? Infection is acquired by ingestion. The jejunum and ileum are the first sites to become colonized. The organisms are invasive; in well developed infections the mesenteric lymph nodes are enlarged. Clinical features The average incubation period is 3 days with a range of 1-7 days. Abdominal pain and diarrhoea are main symptoms. Severe watery diarrhoea may lead to prostration. Leucocytes are almost always present in the feces and .frank blood may be apparent. Symptoms usually resolve within few day.s. Sequaleae of Campylobacter jejuni infection There are two conditions that may arise 1-2 weeks after the infection. Guillain Barre Syndrome -Guillain Barre syndrome (GBS) a demyelenating disorder resulting in acute neuromuscular paralysis is a serious sequlae of campylobacter jejuni infection. - An estimated one case of GBS occurs for every 1000 cases of campvlobacteriosis. Upto 40% of patients with this syndrome have evidence of recent campylobacter infection. 2) Reiters Syndrome -A reactive (aseptic) ahritis affects 1-2% of patients. - It typically affects the knees, ankles and wrists.

In humans, they are seen in relation to the nasal cavity, and enclose the paranasal sinuses. Besides making the skull light in weight, they also help in resonance of sound and act as air conditioning chambers for the inspired air.Pneumatic bones are-maxilla, frontal bone, sphenoid and ethmoid.The mastoid is also most commonly a pneumatic (air filled) bone which encloses numerous air cell spaces giving it a honeycomb appearance. However in some people the mastoid may be diploic (marrow filled) or sclerotic (solid bone without air).

It is of two types:(i) Cytoplasmic (c) ANCA: Refers antibodies against proteinase-3 in azurophilic granules. It is found in - weger's granulomatosis(ii) Perinuclear (p) ANCA: Refers antibodies against myeloperoxidase (major target), elastase, cathepsin G, Lactoferin, Lysozyme.# ANCA is found in: PAN, Microscopic polyangitis, Churg-Strauss syndrome, Crescentic GN, Good-pasture's syndrome Non vascular causes like rheumatic and non-rheumatic autoimmune diseases, IBD, drugs, endocarditis, bacterial infections in patient of cystic fibrosis, primary sclerosing cholangitis etc.> There are three primary diseases that are consistently associated with ANCA: Wegener's granulomatosis, microscopic polyangiitis, and glomerulonephritis. The antibodies are assumed to be involved in the generation and/or progression of lesions and clinical signs.> Classically, c-ANCA is associated with Wegener's granulomatosis; p-ANCA is associated with microscopic polyangiitis arid focal necrotizing and crescentic glomerulonephritis. However, in recent years ANCA targeted against other autoantigens have been identified.> Patients with a number of other diseases, such as ulcerative colitis and Ankylosing spondylitis, will commonly have ANCA as well.> However in these cases there is no associated vasculitis, and the ANCA are thought to be incidental or epiphenomena rather than part of the disease itself.> Churg-Strauss syndrome is associated with p-ANCA directed against MPO.

A 20 year old primi at 30 weeks of gestation has polyhydraminos. She should be advised:-
|
Indomethacin acts by decreasing fetal urine production and thereby reduces amnionic fluid volume. This is presumed due to an increase in vasopressin levels and vasopressin responsiveness However, it may cause constriction of fetal ductus aeriosus, resulting in pulmonary hypeension. Hence, should not be used beyond 32 weeks

30-year-old married female who has been diagnosed as case of prolactinoma in your hospital. Her MRI Pituitary shows a 5 mm microadenoma. She is currently on bromocriptine and her urine pregnancy test has turned positive. What is the best advice for her?
|
This is an interdisciplinary question and has been discussed here to widen the scope of discussion. The guidelines are that once a lady with prolactinoma on Bromocriptine conceives, all drug treatment should be stopped to reduce possibility of any teratogenic effect on fetus. Monitor her Prolactin levels and only if headache and visual symptoms develop that bromocriptine can be re-staed. Harrison snap shot is attached for reference. Mechanical contraception should be used through three regular menstrual cycles to allow for conception timing. When pregnancy is confirmed, bromocriptine should be discontinued and PRL levels followed serially, especially if headaches or visual symptoms occur. For women harboring macrodenomas, regular visual field testing is recommended, and the drug should be reinstituted if tumor growth is apparent. Although pituitary MRI may be safe during .

Typical location is bifrontal or occipital,o Headache gets worsen on sitting or upright posture and is relieved by lying down position and abdominal pressure - The hallmark of postdural puncture headache i.e.. association with body position,o The onset of headache is usually 12-72 hours following the procedure, however, it may be seen almost immediately. In most cases it lasts for 7-10 days.o PDPH is believed to result from leakage of CSF from a dural defect and decreased ICT. Loss ofCSF ata rate faster that it can be produced causes traction on structure supporting the brain, particularly dura and tentorium. Traction on cranial nerve (particularly 6th nerve) produces diplopia,o Factors that increase the incidence of PDPH art young age, female sex, Pregnancy, large bore needle and multiple punctures.o Use of small bore needle can prevent PDPH .o Intially conservative treatment is given which includes analgesics (NSAIDs), oral or i.v., fluids, Sumatriptan, cosyntropin, caffeine and recumbent position.o If conservative treatment fails, epidural blood patch can be used. It involves injecting 15-20 ml of autologus blood into the epidural space which stop leakage of CSF by coagulation and mass effect.

The Most common type of imperforate anus is
|
(C) Anorectal agenesis # Imperforate anus> (The term is used as a well-recognised description. Strictly it should be 'agenesis' and 'atresia' of the rectum and anus.)> One infant in 4500 is born with an imperforate anus, or with imperfect fusion of the post-allantoic gut with the proctodaeum.> The condition is divided into two main groups: the high and the low, depending on whether the termination of the bowel is above or below the pelvic floor.> Low varieties are easy to diagnose and relatively simple to treat, and the outlook is good.> High varieties often have a fistula into the urinary tract together with a deficient pelvic floor, and are difficult to treat.# Low abnormalities:> Covered anus. The underlying anal canal is covered by a bar of skin with atrack running forwards to the perineal raphe. The track should be opened with scissors, followed by routine dilatation of the anus.> Ectopic anus. The anus is situated anteriorly and may open in the perineum in boys, or more commonly in the vulva in girls, or rarely into thevagina. A plastic 'cut back' operation isrequired (Pena).> Stenosed anus. The anus is microscopic, but careful examination usually reveals a minute opening which responds to regular dilatation.> Membranous stenosis. Here the anus is normally sited, but is covered with a thin membrane which bulges with retained meconium. It is rare, and an incision will cure the condition.# High abnormalities:> These are often associated with a fistulous connection between the blind rectal stump and the bladder, or other abnormalities of the pelvic structures.> Anorectai agnesis. A blind rectal pouch lies just above the pelvic floor -- its anterior aspect in the male is attached to the bladder and often there is a rectovesical fistula manifested by the passage of gas or meconium in the urine. In the female, the fistula is usually into the posterior fornix.> Rectal atresia. The anal canal is normal but ends blindly at the level of the pelvic floor. The bowel also ends blindly above the pelvic floor without a fistulous opening. This anomaly is rare but must be treated by mobilisation of the rectum and excision of the stricture. After that, end-to-end anastomosis of the anus and rectum must be attempted.> More conservative measures are followed by an intractable stricture.> Cloaca. This occurs only in females and here the bowel, urinary and genital tracts all open into a common wide cavity. Commonly severe malformations of the area are associated with other developmental abnormalities, e.g. tracheobronchial fistula.

An individual has been on a fad diet for 6 weeks and has begun to develop a number of skin rashes, diarrhea, and forgetfulness. These symptoms could have been less severe if the diet contained a high content of which one of the following?
|
At least eight different carrier proteins transport different groups of amino acids.a. Sodium-amino acid carrier system(1). A number of transport systems involve the uptake by the cell of a sodium ion and an amino acid by the same carrier protein on the luminal surface (examples are systems A, ASC, N, and B).(2). The sodium ion is pumped from the cell into the blood by the Na+-K+ ATPase, whereas the amino acid travels down its concentration gradient into the blood.(a). Thus, the transport of amino acids from the intestinal lumen to the blood is driven by the hydrolysis of adenosine triphosphate (ATP) (secondary active transport).b. The L-system of amino acid transport is not dependent on sodium for cotransport. The L-system transports branched-chain and aromatic amino acids and will be exploited in a treatment for phenylketonuria (PKU).The individual has developed pellagra caused by a lack of dietary niacin. Although dietary niacin is the major source of the nicotinamide ring of NAD, it may also be produced from excess tryptophan. Tyrosine, thiamine, thymine, and riboflavin cannot contribute to the synthesis of the nicotinamide ring of NAD.

Which of the following is used as preanesthetic medication which causes the longest amnesia?
|
The longest amnesia is produced by lorazepam although half life of lorazepam (15 hours) is shoer than diazepam (36 hours) and this is probably because of its strong receptor binding potential. Its relatively potent amnesic effect, with its anxiolytic and sedative effects, makes lorazepam useful as premedication.

A 38-year old woman presented with shoness of breath and fatigue. Her history is unremarkable except for a vague history of fever and joint pain as a child. She notes some recent fatigue and difficulty in sleeping that she attributes to job-related stress. On examination, her hea rate is 120 beats/min. ECG of the patient is given ECHO revealed following finding. Auscultation of the hea indicates a systolic murmur (during left ventricular ejection of blood) that is harsh in character. Which of the following pathological finding is not related with the underlying etiology: -
|
ECG shows atrial fibrillation and ECHO shows Left atrial enlargement. Images FINDINGS: Acute and chronic rheumatic hea disease A-Aschoff body in a patient with acute rheumatic carditis. B- Acute rheumatic mitral valvulitis: Small vegetations (verrucae) are visible along the line of closure of the mitral valve leaflet C- Neovascularization of anterior mitral leaflet D- Myxomatous degeneration of the mitral valve. This 35-year-old woman most likely has atrial fibrillation with tachycardia that is irregularly irregular. One common cause of atrial fibrillation is left atrial enlargement. In this patient, the history of childhood fever and joint pain likely is the result of streptococcal caused rheumatic fever. If untreated, the microorganism can cause inflammation of the mitral valve, leading to mitral stenosis. After 3-5 years, the mitral stenosis is likely to worsen, leading to atrial enlargement, fibrillation, and pulmonary edema with intolerance to physical exeion.
