Mucoepidermoid carcinoma arises form
|
Mucoepidermoid carcinomas are composed of variable mixtures of squamous cells, mucus-secreting cells, and intermediate cells. "The low-grade mucoepidermoid carcinoma is composed of largely mucin-secreting cells, whereas in high-grade tumors, the epidermoid cells predominate." They are the most common malignant tumors of the salivary glands. Treatment The primary t/t of all salivary malignancy is surgical excision: for parotid malignancies- Superficial parotidectomy with preservation of CN VII. Total parotidectomy with nerve preservation if deep lobe is involved. for other salivary gland - Enbloc removal of the involved gland Neck dissection for lymph nodes is done clinically palpable nodes for high grade malignancies Radiation therapy is used postoperatively for specific indications high grade histology presence of extraglandular disease perineural invasion direct invasion of regional structureregional metastasis

True statement about diphtheria toxin is
|
Toxigenicity of the diphtheria bacilli depends on the presence in it of corynephages which acts as the genetic determinant controlling toxin production. The diphtheria toxin acts by inhibiting protein synthesis. Specifically, a fragment B heparin binding and fragment A inhibits polypeptide chain elongation in the presence of nicotinamide adenine dinucleotide by inactivating the elongation factor EF-2.

|
The blending effect is predominantly related to smaller restorations, surrounded by hard dental tissues, such as composite restorations. It can reduce suboptimal shade matches due to operational error or lack of satisfactory match in the shade guide or restorative material. The veneers designed with “contact lens effect” margins before and after cementation are another example of blending effect.

Carey coombs murmur, which is false -
|
A sho, mid-diastolic murmur is rarely heard during an episode of acute rheumatic fever (Carey-Coombs murmur) and probably is due to flow through an edematous mitral valve. An opening snap is not present in the acute phase, and the murmur dissipates with resolution of the acute attack. Complete hea block with dyssynchronous atrial and ventricular activation may be associated with intermittent mid- to late diastolic murmurs if atrial contraction occurs when the mitral valve is paially closed. Mid-diastolic murmurs indicative of increased tricuspid valve flow can occur with severe, isolated TR and with large ASDs and significant left-to-right shunting. Other signs of an ASD are present ( Chap. 236 ), including fixed splitting of S 2 and a mid-systolic murmur at the mid- to upper left sternal border. TTE is indicated for evaluation of a patient with a mid- to late diastolic murmur. Harrison principal of internal medicine,20edition,pg no.1432

Tolvaptan is approved for use in-
|
Tolvaptan is a vasopressor receptor antagonist used to correct hyponatremia in the treatment of syndrome of inappropriate water excretion or SIADH :-
Syndrome of inappropriate secretion of ADH is caused due to excesive secretion of antiduretic hormone.
Antidiuertic hormone (ADH) or arginine vasopressin is synthesized by the hypothalamus.
Its major effect is to prevent diuresis by promoting reabsorption of water in the kidneys.
- ADH is the primary physiological determinant of the rate of free water excretion.
- Its major renal affect is to augument the water permeability of the leminal membranes of the cortical and medullary collecting tubules thereby promoting water reabsorption.
The antidiuretic effect of ADH is mediated by "V2 receptors".
Tolvaptan is V2 receptor antagonist
- It can be used to correct hyponatremia due to excesive water retnetion caused by increased ADH secretion.
Randomized double blind trials have shown that oral or intravenous vasopressin antagonists are more effective than placebo in raising the serum sodium of hyponatremic patients.
"Tolvaptan" and "conivaptan" but not lixivaptan are approved for use in the united states.
Vasopressor receptor antagonist
There are three receptor for vasopressin (ADH).
- The V1 a, Vlb and V2 receptors.
The V2 receptors primarily mediate the antidiuretic response while V1 a and Vlb primarily cause vasoconstriction and adrenocorticotropic hormone (ACTH) release.
V2 → Mediate antidiuretic response
VlaVlb → Cause vasoconstriction and adrenocorticotropic hormone (ACTH) release.
The vasopressin receptor antagonist tolavaptan produces a selective water diuresis (aquaresis) without affecting sodium and potassium excretion.
- The ensuing loss of electrolyte free water will tend to raise the serum sodium in patients with SIADH and may improve mental status in patients with serum sodium under 130 meq/L.

|
Ans. a (Lactose) (Ref OP Ghai 6th/ p. 158; 7th/p. 131, 134)After premature delivery, mother's milk is low in:# Calcium # Phosphates # LactoseADVANTAGES OF BREAST MILK# Docosahexanoic acid (DHA, W3, 2:3) present in breast milk helps in brain development.# Maximum synthesis of breast milk occurs at 12 months.# Has better calcium than cow milk for baby to absorb.# Iron in breast has 70% availablity. # Prevents against infections by:- Human milk contains bacterial and viral antibodies, including secretory IgA. They probably account for the lower incidence of diarrhea, otitis media, pneumonia, bacteremia, and meningitis during the 1st yr of life.e- Macrophages in human milk may synthesize complement, lysozyme, and lactoferrin.- Lactoferrin has an inhibitory effect on the growth of Escherichia coli in the intestine.- The lower pH of the stool of breast-fed infants is thought to contribute to the favorable intestinal flora of infants fed human milk vs. formula (i.e., more bifidobacteria and lactobacilli; fewer E. coli), which also helps protect against infections caused by some species of E. coli.- Human milk also contains bile salt-stimulated lipase, which kills Giardia lamblia and Entamoeba histolytica.DISADVANTAGES OF BREAST MILK# Breast milk is balanced, will supply all the necessary nutrients except, perhaps, fluoride and, after several months, vitamin D.# The iron content of human milk is somewhat low. However, most normal infants have sufficient iron stores for the first 6 mo of life. Moreover, human milk iron is well absorbed.# The vitamin K content of human milk also is low and may contribute to hemorrhagic disease of the newborn. Parenteral administration of 1 mg of vitamin K, at birth is recommended for all infants, edpecially for those who will be breast- fed.# Cytomegalovirus (CMV), human T-cell lymphotropic virus type 1, rubella virus, hepatitis B virus, and herpes simplex virus also have been demonstrated in breast milk. Of these, the presence of CMV is the most troublesome.Nutritive value of milk compared BuffaloCowGoatHuman1Fat (g)6.54.14.53.42Protein (g)4.33.23.31.13Lactose (g)5.14.44.67.1Q4Calcium (mg)210120170285Iron (mg)0.20.20.3--6Vitamin C (mg)12137Minerals (g)0.80.80.80.18Water (g)81.08786.888

Shoest acting anticholinesterase is -

Ans. is 'a' i.e., Edrophonium o Edrophonium is the shoest acting anti-ChE. o Why is it so, lets see : o When carbamates (other than edrophonium) and organophophates react with cholinesterase, they form covalent bond at esteratic site, which is considerably resistant to hydrolysis. o In contrast, edrophonium binds electrostatically and by hydrogen bonds at anionic site (not at esteratic site) of cholinesterase. The enzyme inhibitor complex does not involve a covalent bond and is correspondingly sho lived (2-10 minutes). o So edrophonium is also called as noncovalent inhibitor.

Ans. D: Hypochondriasis Hypochondriasis, hypochondria refers to excessive preoccupation or worry about having a serious illness. An individual suffering from hypochondriasis is known as a hypochondriac. Often, hypochondria persists even after a physician has evaluated a person and reassured them that their concerns about symptoms do not have an underlying medical basis or, if there is a medical illness, the concerns are far in excess of what is appropriate for the level of disease. Many hypochondriacs focus on a paicular symptom as the catalyst of their worrying, such as gastro-intestinal problems, palpitations, or muscle fatigue.

The treatment of acute myocardial infarction includes which of the following-
|
Ref : harrisons-manual-of-medicine-16th-edition pg no: 622-623 TREATMENT Initial Therapy Initial goals are to: (1) quickly identify if patient is candidate for reperfusion therapy, (2) relieve pain, and (3) prevent/treat arrhythmias and mechanical complications. * Aspirin should be administered immediately (162-325 mg chewed at presentation, then 162-325 mg PO qd), unless pt is aspirin-intolerant. * Perform targeted history, exam, and ECG to identify STEMI (1 mmST elevation in two contiguous leads or new LBBB) and appropriateness of reperfusion therapy , which reduces infarct size, LV dysfunction, and moality. * Primary PCI is generally more effective than fibrinolysis and is preferred at experienced centers capable of performing procedure rapidly , especially when diagnosis is in doubt, cardiogenic shock is present, bleeding risk is increased, or if symptoms have been present for 3 h. * Proceed with IV fibrinolysis if PCI is not available or if logistics would delay PCI 1 h longer than fibrinolysis could be initiated (Fig. 123-1). Dooo- needle time should be 30 min for maximum benefit. Ensure absence of contraindications before administering fibrinolytic agent. Those treated within 1-3 h benefit most; can still be useful up to 12 h if chest pain is persistent or ST remains elevated in leads that have not developed new Q waves. Complications include bleeding, reperfusion arrhythmias, and, in case of streptokinase (SK), allergic reactions. Heparin should be initiated with fibrinolytic agents other than SK ; maintain aPTTT at 1.5-2.0 control (50-70 s). * If chest pain or ST elevation persists 90 min after fibrinolysis, consider referral for rescue PCI. Later coronary angiography after fibrinolysis generally reserved for pts with recurrent angina or positive stress test. The initial management of NSTEMI (non-Q MI) is different . In paicular, fibrinolytic therapy should not be administered.

In surgical anterolateral approach to tibia, incision is taken over the tibialis anterior muscle mass rather than over the shaft. What is/ are the advantages?
|
Ans. is 'd' i.e., All the above * In surgical anterolateral approach to tibia, incision is taken over the tibialis anterior muscle mass rather than over the shaft. Following are the advantages :i) If required can be converted to an extensile approach. Entire tibia from knee to ankle can be exposed.ii) Open wound treatment of the fracture is possible with this incision with proper planning i.e. in cases where the fracture is compound and/ or there is excess tension while closing the wound, the surgical wound can be left open - with adequate planning the bones and implants will remain adequately covered by the medial flap.iii) Medially based flap - since the incision is lateral to the subcutaneous surface, the skin flap will be based medially, in an area of higher vascularity and skin sloughs will not normally occur.

A young patient had a history of fall. The physician placed his hand on the patient's chin and instruct him to rotate his head to the opposite side against resistance. But he was unable to perform the action. Which of the nerve is injured in this patient?
|
The sternocleidomastoid muscle creates the borders for both the anterior and the posterior triangles of the neck, and is innervated by the spinal accessory nerve (CN XI). To test the sternocleidomastoid muscle, the physician will place her hand on the patient's chin and instruct him to rotate his head to the opposite side against resistance. If acting normally, the patient's muscle can be seen and palpated. The physician next will instruct the patient to shrug his shoulders against resistance. Patients with damage to CN XI will have diminished shoulder strength while shrugging on the injured side.

Local anesthetic action is a result of blockade of the movement of wof channels
|
LOCAL ANAESTHETICS MECHANISM OF ACTION The LAs block nerve conduction by decreasing the entry of Na+ ions during upstroke of action potential (AP). As the concentration of the LA is increased, the rate of rise of AP and maximum depolarization decreases causing slowing of conduction. Finally, local depolarization fails to reach the threshold potential and conduction block ensues. The LAs interact with a receptor situated within the voltage sensitive Na+ channel and raise the threshold of channel opening: Na+ permeability fails to increase in response to an impulse or stimulus. Impulse conduction is interrupted when the Na+ channels over a critical length of the fibre (2-3 nodes of Ranvier in case of myelinated fibres) are blocked. Ref:- kd tripathi; pg num:-361

|
* The urine electrolytes are used to distinguish between A and diarrhea * UAG is an indirect measure of ammonium excretion * UAG = (Na + K) - Cl * UAG = ( 100 + 31 ) - 105 = 26 * A positive UAG suggest A because in the setting of diarrhea, ammonium chloride concentration in the urine would be high and the UAG would be negative. * A positive value suggests that the kidney is unable to adequately excrete ammonium, leading to a reduction in net acid excretion and thus metabolic acidosis.

Prolonged latent phase is seen in :
|
In primi, the latent phase is often long (about 8 hours) during which effacement occurs; the cervical dilatation averaging only 0.35 cm/hr. In multi, the latent phase is sho (about 4 hours) and effacement and dilatation occur simultaneously. Latent phase is the preparatory phase of the uterus and the cervix before the actual onset of labor. A latent phase that exceeds 20 hours in primigravidae or 14 hours in multiparae is abnormal. The causes include--(1) unripe cervix (2) malposition and malpresentation (3) cephalopelvic dispropoion and (4) premature rupture of the membranes. Management: Expectant management is usually done unless there is any indication (for the fetus or the mother) for expediting the delivery. Rest and analgesic are usually given. When augmentation is decided, medical methods are preferred. Amniotomy is usually avoided. Prolonged latent phase is not an indication for cesarean delivery.

You are in the causlity when a student, Kumar is brought in with a shoulder injury sustained while playing football. In comparing the symmetry of his two shoulders, you notice a marked elevation of the distal end of his clavicle with respect to the acromion on the injured side. X-ray exam reveals a grade III shoulder separation. In order for this to have occurred, which ligament must be torn?
|
A shoulder separation is an injury to the acromioclavicular joint. A first degree separation involves stretching the ligaments, but maintenance of the joint. A second degree separation involves tearing of the joint capsule and coracoclavicular ligament, but still continuity. A third degree separation involves total disruption of the joint and the coracoclavicular ligament. Since the patient has a third degree shoulder separation, you know he must have torn his coracoclavicular ligament. The coracoacromial ligament contributes to the stability of the acromioclavicular joint, but damaging this ligament is not the hallmark of a third degree shoulder separation. The costoclavicular ligament connects the first rib to the clavicle. The superior glenohumeral ligament contributes to the stability of the shoulder joint, but not to the stability of the acromioclavicular joint. The transverse humeral ligament holds the tendon of the long head of the biceps in place in the inteubercular groove.

Hemolytic uremic syndrome
Hemolytic uremic syndrome is characterized by the triad of :
Anemia (microangiopathic hemolytic anemia).
Renal failure (microangiopathy of kidney involving glomerular capillaries and arterioles).
Thrombocytopenia (due to platelet consumption).
Hemolytic uremic syndrome is most common is children under 2 years of age.
It usually follows an episode of acute gastroenterities, often triggered by E coli.
The prodrome is usually of abdominal pain, diarrhoea and vomiting.
Shortly thereafter, signs and symptoms of acute hemolytic anemia, thrombocytopenia and acute renal failure ensue.
Sometimes neurological findings also occur. (But usually absent and differentiate HUS from TTP.)
Rarely HUS may follow respiratory tract infection.
Etiology
Gastrointestinal infection in infants with the following organism :
E coli, Shigella dysenteriae, Streptococouus pneumoniae
Hematological findings in a case of microangiopathic hemolytic anemia :
Presence of schistocytes (fragmented red cells). This is the hallmark of microangiopathic hemolytic anemia.
Neutrophil leukocytosis.
Thrombocytopenia.
Hemoglobinuria is mild to moderate with hemosiderinuria.

|
Ans. is 'a' i.e., Can differentiate into all the tissues of embryonic or extraembryonic cell types Stem cells base on their potency* Potency refers to ability of stem cells to differentiate into specialized (mature) cell type:-A. Totipotent stem cells - These cells are produced from fertilization of sperm and ovum and cells that are produced by first few division after fertilization are also totipotent. These cell can differentiate into all the tissues of embryonic or extra embryonic cell types.B. Pluripotent stem cells - These are descendants of totipotent stem cells and can differentiate into cells derived from any of the three germ layers.C. Multipotent stem cells - These cells can differentiate only into cells of a closely related family, e.g. hematopoietic stem cells differentiate into RBC, WBC, platelets but not into other types.D. Unipotent stem cells - Can differentiate only in to one cell type (e.g. muscle stem cell), but have property of self-renewal which distinguiches them from non-stem cells.

They are ordinarily non-pathogenic. The resemble Staphylococci, but in general, they are large in size and tetrads. The common laboratory test used to differentiate between micrococci and staphylococci is modified oxidase test.Ref: Ananthanarayan 9th edition, p206

For children >3 months old, the most common organisms are S. pneumoniae, Neisseria meningitidis, and Staphylococcus aureus, with a lower incidence of S. pneumoniae meningitis since routine vaccinations with the conjugate vaccine. Penicillin has long been the treatment of choice for meningococcal infections and sulfonamides are used only for chemoprophylaxis because of resistance. Serogroup A epidemics have been largely confined to tropical countries. Both MCV4 and MPSV4 can be given to individuals who are immunosuppressed. Ref: Ray C.G., Ryan K.J. (2010). Chapter 30.

False-positive results are encountered with yolk-sac tumors and many non-neoplastic conditions, including cirrhosis, massive liver necrosis, chronic hepatitis, normal pregnancy, fetal distress or death, and fetal neural tube defects such as anencephaly and spina bifida.
Concept
The staining for Glypican-3 is used to distinguish early hepatocellular carcinoma from a dysplastic nodule. Other tests cannot be used because the levels of serum α-fetoprotein are inconclusive in this condition.
