A 65 year old elderly male has history of sweating and chest pain for last 24 hrs with the following ECG. Which of the following is not given in managing the patient? | Ans. C. Thrombolytic therapyFirst let us diagnose the ECG; we need to know the following points:E.C.G changes in acute infarctionEarly acute phase (with - in hours)Fully evolved phaseOld infarction (resolution phase)Elevation of ST segmentPathological Q warePathogical Q waveTall wide (peaked) T waveElevated ST segment being to resolveT wave inverts.ST segment and T wave may be normalST segment elevation, unlike depression, will localize to the ECG lead of the affected myocardium. Note that 1mm of ST elevation in 2 contiguous leads is required to diagnose STEMI, however there are two major exceptions.a. Anterior STEMI requires 2mm of ST elevation in V2 and V3 in men > 40 years old or 1.5mm in women according to the ACC/AHA definition.b. Posterior STEMI frequently has ST depression in V1-V3 instead of elevation since the vectors are completely reversed. Hence, this is an ECG of anterior STEMI.In STEMI, thrombolysis or PCI (primary PCI) are effective methods to restore coronary blood flow and salvage myocardium within the first 12 h after onset of chest pain.ST elevation MI (STEMI) Immediate management:a.

Hemoglobin does not bind with: | Hemoglobin Combines Reversibly With Oxygen.
Carbon monoxide (CO) combines with hemoglobin at the same point on the hemoglobin molecule as does O2 ; it can therefore displace O2 from the hemoglobin.
CO2 reacts directly with amine radicals of the hemoglobin molecule to form the compound carbaminohemoglobin (CO2 Hgb).
This combination of CO2 and hemoglobin is a reversible reaction that occurs with a loose bond, so the CO2 is easily released into the alveoli, where the PCO2 is lower than in the pulmonary capillaries.

Which of the following factors of balanced occlusion is given by the patient? | Condylar guidance
Definition: The mechanical form located in the upper posterior region of an articulator that controls movement of its mobile member (GPT8).
Condylar guide inclination: The angle formed by the inclination of a condylar guide control surface of an articulator and a specified reference plane (GPT8).
This is the mandibular guidance generated by the condyles traversing the contours of the glenoid fossa.
It is duplicated in the articulator. The extent of duplication depends on the articulator’s capability, whether it is semi-adjustable or fully adjustable.
Protrusive condylar guidance is obtained using protrusive records,while the lateral condylar guidance is obtained using Hanau’s formula or lateral records
It is designated as an inclination or angle – condylar guidance angle or inclination – and is expressed in degrees.
This is the only factor that is obtained from the patient and is not under the dentist’s control.
A shallow condylar guidance will cause less posterior tooth separation in protrusion and requires teeth with shorter cusps and flatter fossa to achieve balanced occlusion, than a steep guidance.
Key Concept:
Out of the five factors of balanced occlusion, only condylar guidance is recorded from the patient by the means of protrusive records. | 1 | Condylar guidance | Incisal guidance | Inclination of the cusps | Orientation of the occlusal plane | Dental | null | b83f9ab5-f08b-4b4c-abe5-7dc84b4efa71 | single |

Peripheral resistance is best indicated by: | Ans. a. Diastolic blood pressure Aerial hypeension is the result of abnormal flow/resistance relationships. Resistance to outflow consists of different components: the systolic component is the one generated by conductance vessels, whereas the diastolic component consists of peripheral resistance, which regulates peripheral blood supply due to the run-off of conductance vessels during left ventricular diastole. Thus, an increase in systemic resistance results in a rise in diastolic blood pressure. If the elasticity of conductance vessels decreases, diastolic run-off also decreases and diastolic blood pressure goes down. When this loss of elasticity occurs, the ejection force cannot be anymore offset by aerial distension, the pulse wave velocity increases and reflex waves to the hea arrive earlier, causing the systolic blood pressure to augment. Such an augmentation, together with decreasing diastolic blood pressure results in an enhancement of the pulse pressure. When the stroke volume is normal, an increase in pulse pressure is, therefore, a marker of altered conductance. However, if, due to loss of elasticity of the conductance aeries diastolic blood pressure goes down, increasing systolic pressure also protects against a decrease in mean pressure. Indeed, in conditions of elevated pulse pressure, the mean pressure can be normal or high, indicating that when evaluating blood pressure all components should be taken into consideration. A high systolic blood pressure associated with a normal mean blood pressure is suggestive of a normal peripheral resistance.'Diastolic PressureSystolic pressure is peak pressure reached during systole, similarly, diastolic pressure refers to lowest pressure during diastole.Diastolic blood pressure is an index to peripheral resistance.Elasticity of aoa and large aeries is mainly responsible for origin and maintenance of diastolic pressure (by Windkessel elastic recoil effect).Because the elasticity is higher in younger subjects, diastolic pressure is maintained and pulse pressure is narrow.Because the elasticity is lower in old persons, diastolic pressure is decreased and pulse pressure is widened. | 1 | Diastolic blood pressure | Pulse pressure | Systolic resistance in aoa as it increases in its length | Mean aerial pressure, which is responsible for blood flow to an organ | Anatomy | null | 09692eda-4a95-4613-9855-ed141332239b | single |

All of the following statements about the control of micturition are true except: | Micturition is initiated by activation of afferent sensory fibers located in the wall of the bladder; these fibers sense the degree of stretch of the bladder wall. In addition, these sensory fibers travel back to the spinal cord via sacral dorsal roots. The sensory information that reaches the spinal cord also travels to the micturition center in the rostral pons. When sensory activity to the micturition center is sufficient, a command is sent to the sacral spinal cord, leading to activation of parasympathetic fibers. The parasympathetic fibers travel to the bladder via the pelvic nerve. Activation of these fibers leads to bladder contraction. Destruction of the sacral dorsal roots (as occurs with tabes dorsalis) abolishes the reflex because sensory afferent fibers no longer send signals back to the spinal cord.
A spinal cord injury at L1 is well above the sacral region where the micturition reflex originates. How ever, the central nervous system (CNS) plays an important role in facilitating or inhibiting the micturition reflex, and this function is lost with spinal cord injury. Although some patients with spinal cord injury can still elicit a micturition response (e.g., stroking of the skin in the genital region), the bladder in these patients has increased muscle tone and fails to empty completely. As the bladder becomes more and more distended, an involuntary micturition reflex can occur. However, the CNS can keep urine from being voided under these circumstances by maintaining a constant tonic contraction of the external sphincter. This contraction is accomplished through continued activation of so matic nerves that travel in the pudendal nerve from the sacral spinal cord to the external sphincter. The point at which an urge to void first occurs corresponds to a bladder volume of approximately 150 ml. However, bladder volume can increase more than twofold before involuntary micturition occurs. At 400 ml a marked sense of fullness is present. Parasympathetic fibers originating in the sacral spinal cord innervate the body of the bladder, and it is activation of these fibers that leads to bladder contraction. | 4 | An individual with a spinal cord injury at L1 can still have a micturition reflex | The micturition reflex can occur without voiding any urine | Bladder volume can be more than double that present when the first urge to void occurs | An individual with destruction of the sacral dorsal roots can still have a micturition reflex | Unknown | null | 252913b9-b0a6-4d3b-8ce3-bde27270ff05 | multi |
Drug of choice for a case of uncomplicated cystitis - | Ans. is 'd' i.e.. Fosfomycin[Ref: OBJECTIVE: To determine the drug of choice for the treatment of uncomplicated cystitis. METHOD: Drug selection was performed by means of the so-called 'system of objectified judgment analysis' (SOJA) method by a working group of 11 persons. The following selection criteria were used: pharmacokinetics, interactions, the probability of hitting (the probability that the microorganism is sensitive to the antibiotic), development of resistance, specific use in urinary tract infections, efficacy, side effects, dosage-frequency, duration of treatment, cost and documentation. The following drugs were included in the study: amoxicillin (with or without clavulanic acid), nitrofurantoin, sulfamethizole, trimethoprim, co-trimoxazole, ciprofloxacin, norfloxacin, ofloxacin and fosfomycin trometamol. RESULTS: Fosfomycin and nitrofurantoin slow release showed the highest scores. The main selection criteria that determined the selection of a drug were especially specific use in urinary tract infections, development of resistance, the probability of hitting and cost. CONCLUSION: Fosfomycin and nitrofurantoin slow release best fulfill the requirements for drugs in the treatment of uncomplicated cystitis. No comparative studies have been performed with the 3-day treatment of uncomplicated cystitis with nitrofurantoin slow release or with trimethoprim. Fluoroquinolones play no important part in the treatment of uncomplicated cystitis, mainly because of the risk of development of resistance. | 4 | Amoxicillin | Chloramphenicol | Cotrimoxazole | Fosfomycin | Unknown | null | f8d81666-78dc-4e80-9035-12a7fe2d787a | single |

Allergic rhinitis is which type of hypersensitivity- | Ans. is 'a' i.e., Type -1 Pathogenesis of allergic rhinitiso Allergic rhinitis is a type I hypersensitivityIt occurs in two phases:-1) Initial response/Acute or early phase# After first antigen exposure, this antigen is presented to CD-4 helper T cells (TH, type) by antigen presenting cells. These primed TH, cells release IL-4 that acts on B-cells to form Ig E specific for that particular antigen. The antigen specific Ig E antibodies then bind to the surface receptors of mast cells and basophils. The process from first antigen exposure to the coating of mast cells by Ig E acts as sensitization (prior sensitization) and first exposure is also called priming or sensitizing exposure (dose). Subsequent exposure (shocking dose) to same antigen then results in activation of mast cells and basophils with release of inflammatory mediators : -i) Histamine (most important)ii) Hepariniii) Leukotriens (B4, C4> D4)iv) PGD2v) PAFvi) Cytokines (IL-1, 3, 4, 5, 6; INF)vii) Eosinophil chemolactic factor (ECF)viii) Neutrophil chemolactic factor (NCF)The release of these mediators result in : -Increased vascular permeability and vasodilatation which result in tissue edema - Nasal blockage and sneezing.Smooth muscle spasm - BronchoconstrictionHyperactivity of glands - RhinorrheaRecruitment of inflammatory cells.2) Late phase responseRecruited inflammatory cells of initial phase amplify and sustain the inflammatory response without additional exposure to the triggered antigen. PAF is the most important mediator in initiation of late phase response. Eosinophils are particularly important cells among the recruited cells which also include neutrophils, basophils, monocytes and T-cells.

Red degeneration most commonly occurs in | Ans. is 'b' i.e. 2nd Trimester Red degeneration of the myomasRed degeneration of uterine myomas develops most frequently during pregnancy. It typically occurs during 2nd trimester (20-22) weeks of pregnancy.During red degeneration, the myomas become tense, tender and causes severe abdominal pain with constitutional upset and fever.Although the patient is febrile with moderate Leucocytosis and raised E.S.R., the condition is an aseptic one.It needs to be differentiated from appendicitis, twisted ovarian cyst, pyelitis and accidental hemorrhage.During the red degeneration, the tumour itself assumes a peculiar purple red colour and develops a fishy odour. If the tumour is carefully examined, some of the large veins in the capsule and the small vessels in the substance of the tumour will be found thrombosed. The discoloration is possibly caused by diffusion of blood pigments from thrombosed vessels.Conservative treatment with analgesia, reassurance and supportive therapy is almost always adequate.Also knowAnother complication of myoma which is seen during pregnancy is torsion of the myoma.Torsion of the myoma is also characterized by acute abdominal pain with point tenderness over the site of leiomyoma.Conservative t/t is adequate. | 2 | 1st trimester | 2nd trimester | 3rd trimester | Puerperium | Gynaecology & Obstetrics | Clinical Features, Diagnosis, and Pathology | 318c223a-180d-44cd-b4c3-7e1ba73bea2b | single |

A 5-day-old male infant is diagnosed with Hirschsprung disease. CT scan examination reveals an abnormally dilated colon. Which of the following is the most likely embryologic mechanism responsible for Hirschsprung disease? | Congenital megacolon (Hirschsprung disease) results from the failure of neural crest cells to migrate into the walls of the colon. Incomplete separation of the cloaca would result in anal agenesis either with or without the presence of a fistula. The failure of recanalization of the colon results in rectal atresia, wherein both the anal canal and rectum exist but are not connected due to incomplete canalization or no recanalization. Defective rotation of the hindgut can cause volvulus or twisting of its contents. Oligohydramnios is a deficiency of amniotic fluid, which can cause pulmonary hypoplasia but would not cause Hirschsprung disease. | 1 | Failure of neural crest cells to migrate into the walls of the colon | Incomplete separation of the cloaca | Failure of recanalization of the colon | Defective rotation of the hindgut | Anatomy | Abdomen & Pelvis | fed012ce-cb5d-459c-b0ba-d4ace34d84ca | multi |
