1).HUS is associated with ?
Hemolytic uremic syndrome(HUS), thrombotic thrombocytopenic purpura, and microangiopathic anemia are the dreaded complications of EHEC infection and occur most often in children younger than 10 years, although older children and adults are not always spared.
2).Hering-Breuer reflex is mediated by ?
A. Pulmonary stretch receptor
B. Bronchial stretch receptor
C. J receptor
D. Chest wall proprioceptors
Three respiratory reflexes can be elicited by stimulation of the pulmonary stretch receptors: the Hering-Breuer inflation reflex, the Hering-Breuer deflation reflex, and the “paradoxical” reflex of Head.
3).Clinical features of lower motor neuron lesion include all the following EXCEPT ?
C. Individual muscle paralysis
Lower motor neuron lesions produce the following characteristic signs at the affected levels.
Weakness or paralysis
Wasting and fasciculations of involved muscles
Loss of tendon reflexes when neurons subserving them are affected
Normal abdominal and plantar reflexes—unless the neurons subserving them are directly involved, in which case reflex responses are lost
4).Placental ALP is used as tumor marker of ?
Intratubular germ cell neoplasia and five common types of germ cell tumors (seminoma, embryonal carcinoma, yolk sac tumor, choriocarcinoma, and teratoma
Seminomas tend to remain localized in the testis for a longer period, are radiosensitive, and metastasize to lymph nodes, whereas nonseminomatous neoplasms metastasis sooner, are radioresistant, and tend to metastasize via hematogenous routes.
Seminomas are radiosensitive.
A dysgerminoma is the ovarian correlate of the seminoma (i.e., the tumors have the same features but different names).
Tumor is positive for placental ALP & negative for AFP
Spermatocytic seminoma is morphologic variant that tend to occur in old people
5).Which among the following oral meditation used in the treatment of scabies ?(KARNATAKA 2011)
Ivermectin (22,23-dihydroavermectin) is a derivative of the macrocyclic lactone avermectin produced by the soil-dwelling actinomycete Streptomyces avermitilis.Ivermectin is active at low doses against a wide range of helminths and ectoparasites. It is the drug of choice for the treatment of onchocerciasis, strongyloidiasis, cutaneous larva migrans, and scabies. Ivermectin is highly active against microfilariae of the lymphatic filariasis but has no macrofilaricidal activity.
