An old lady was brought to the ER in an unconscious state. She has a history of previous such attacks in the past months. An ECG was done and the graph obtained is given below. Which of the following is most probable cause? | Ans. D. 2:1 blockElectrocardiography and Electrophysiology of AV conduction blockAV conduction block typically is diagnosed electrocardiographically, which characterizes the severity of the conduction disturbances and allows one to draw inferences about the location of the block. AV conduction block manifests as slow conduction in its mildest forms and failure to conduct, either intermittent of persistently, in more severe varieties.a. First degree AV block (PR interval >200ms) is a slowing of conduction through the AV junction. The site of delay is typically in the AV node but may be in the atria, bundle of his, or his Purkinje system. A wide QRS is suggestive of delay in the AV node proper or less commonly in the bundle of His. In second degree AV block there is an intermittent failure of electrical impulse conduction from atrium to ventricle.b. Second degree AV block is sub classified as Mobitz type I (Wenckebach) or Mobitz type II. The periodic failure of conduction in Mobitz, type I block is characterized by a progressively lengthening PR interval, shortening of the RR interval, and a pause that is less than the two times the immediately preceding RR interval on the electrocardiogram (ECG). The ECG complex after the pause exhibits a shorter PR interval than that immediately preceding the pause. This ECG pattern most often arises because of decremental conduction of electrical impulses in the AV node. | 2,913 | medmcqa_train |

A 6 year old female patient complains of pain due to a decayed lower right 2nd molar. She has a history of unpleasant dental extraction with the lower left second molar. On seeing the dentist, the child immediately cries and withdraws. Which theory of child psychology best explains the reaction of the patient? | Classical conditioning (1927) occurs readily with young children and can have a considerable impact on a young child's behavior on the first visit to a dental office. By the time a child is brought for the first visit to a dentist, even if that visit is at an early age, it is highly likely that he or she will have had many experiences with pediatricians and medical personnel. When a child experiences pain, the reflex reaction is crying and withdrawal. In Pavlovian terms, the infliction of pain is an unconditioned stimulus, but a number of aspects of the setting in which the pain occurs can come to be associated with this unconditioned stimulus. For instance, it is unusual for a child to encounter people who are dressed entirely in white uniforms or long white coats. If the unconditioned stimulus of painful treatment comes to be associated with the conditioned stimulus of white coats, a child may cry and withdraw immediately at the first sight of a white-coated dentist or dental assistant. In this case, the child has learned to associate the conditioned stimulus of pain and the unconditioned stimulus of a white-coated adult, and the mere sight of the white coat is enough to produce the reflex behavior initially associated with pain
Note: A) Acquisition – learning a new experience (fear of dentist/whitecoat/needles)
B) Generalization – generalizing all similar stimuli (all those wearing white coat cause pain)
C) Discrimination – differentiating individual stimuli ( not everyone who wears white coat causes pain)
D) Extinction - disappearance of the acquired experience ( loss of fear of dental procedures)
E) Spontaneous recovery – reappearance of extinct response ( fear of dental procedure reappears due to poor management behaviour strategies). | 2,919 | medmcqa_train |

Familial amylodotic polyneuropathy is due to amyloidosis of nerves caused by deposition of | Ref Robbins 9/e p259 Familial (Hereditary) Amyloidosis A variety of familial forms of amyloidosis have been described; most are rare and occur in limited geographic areas. The best-characterized is an autosomal recessive condition called familial Mediterranean fever. This is a febrile disorder characterized by attacks of fever ccompanied by inflammation of serosal surfaces, includ- ing peritoneum, pleura, and synol membrane. This dis- order is encountered largely in persons of Armenian, Sephardic Jewish, and Arabic origins. It is associated with widespread tissue involvement indistinguishable from reactive systemic amyloidosis. The amyloid fibril proteins are made up of AA proteins, suggesting that this form of amyloidosis is related to the recurrent bouts of inflamma- tion that characterize this disease. The gene for familial Mediterranean fever is called pyrin and encodes a protein that is a component of the inflammasome (Chapter 2). Patients have gain-of-function mutations in pyrin that result in constitutive overproduction of the pro- inflammatory cytokine IL-1 and persistent inflammation. In contrast with familial Mediterranean fever, a group of autosomal dominant familial disorders is characterized by deposition of amyloid predominantly in the peripheral and autonomic nerves. These familial amyloidotic poly- neuropathies have been described in kindreds in different pas of the world--for example, in Pougal, Japan, Sweden, and the United States. As mentioned previously, the fibrils in these familial polyneuropathies are made up of mutant forms of transthyretin (ATTRs). | 2,927 | medmcqa_train |

In transtentorial herniation, a pa of the brain is displaced from the supratentorial to the infratentorial compament through the tentorial opening. It results in all of the following, EXCEPT: | The uncus (on the medial aspect of the temporal lobe) herniates under the tentorium cerebelli. The uncus can compress the oculomotor nerve (CN III), compromising the parasympathetic fibers and resulting in ipsilateral pupillary dilation with associated ophthalmoplegia ("down and out"). Cheyne-Stokes respirations are commonly seen with mesial temporal transtentorial herniation. If the uncus is forced fuher medially, it compresses the cerebral peduncle, producing contralateral hemiparesis. After the brain herniates, the patients are decerebrate and comatose, have fixed and dilated pupils, and eye movements are absent. Ref: Cowan J.A., Thompson B. (2010). Chapter 36. Neurosurgery.

Which of the following is the skeletal muscle relaxant of choice in liver and renal disease ? | Atracurium is degraded by both pH and temperature dependent Hofmann elimination (autolysis) and by ester hydrolysis; it therefore does not require a dosage adjustment in patients with renal or hepatic failure. However, acidosis and severe hypothermia decrease the rate of drug metabolism and should prompt dose reduction. Mivacurium is a sho-acting benzylisoquinoline with an onset of action comparable to atracurium but with one-third its duration of action, because of rapid hydrolysis by plasma pseudocholinesterase. However, patients with renal or hepatic insufficiency may have depressed pseudocholinesterase activity leading to delayed elimination. Vecuronium is an aminosteroid compound with an intermediate duration of action. It is hepatically metabolized to three active metabolites, all of which are eliminated by the kidney. | 2,965 | medmcqa_train |

Higher secondary attack rate means, more numbers of susceptible contacts are developing the disease after exposure to primary case. So, higher the SAR higher is the communicability (infectiousness) of disease. | 2,967 | medmcqa_train |
