Brugada syndrome - most frequently linked to mutations in the Na+ channel α-subunit， SCN5A
Upper motor neuron lesions ALL of the following are CORRECT EXCEPT -
Fasciculations may be a sign of degeneration of lower motor neurons in which case they may be associated with muscle cramps and neuromyotonia.
Which is the VECTOR for Babesiosis?
Babesiosis - Tick-borne
Tsetse flies - Sleeping sickness (African trypanosomiasis) - Parasite
Sandflies - Leishmaniasis.
Lice - Typhus - Louse-borne relapsing fever
Orthostatic hypotension is defined as a reduction in systolic blood pressure of at least ...... mmHg or diastolic blood pressure of at least ..... mmHg within ..... min of standing
Orthostatic hypotension is defined as a reduction in systolic blood pressure of at least 20 mmHg or diastolic blood pressure of at least 10 mmHg within 3 min of standing
Abiliity to identify common objects by palpation, recognizing their shape, texture and size is called as -
Stereognosis
When non painful stimulus is experienced as painful is is called as -
Hypesthesia or hypoethesia refers to a reduction of cutaneous sensation to a specifc type of testing such as pressure， light touch， and warm or cold stimuli
Allodynia describes the situation in which a nonpainful stimulus is experienced as painful
Hyperalgesia denotes severe pain in response to a mildly noxious stimulus
'Maltese crosses' under polarized light are commonly seen in the urinary sediment of patients with -
Maltese crosses under polarized light are commonly seen in the urinary sediment of patients with a nephrotic syndrome
'Maltese cross appearance' in RBCs seen in -
Babesia microti, a hemoprotozoan parasite of rodents, is also important as a zoonotic agent of human babesiosis. The Maltese cross form, which consists of four masses in an erythrocyte, is characteristic of the developmental stage of B. microti.
'Coat-Hanger' headache seen in -
Headache of Orthostatic hypotension - is called coat-hanger ache because it affects the neck and shoulders in a coat-hanger pattern.
Neck pain， typically in the suboccipital， posterior cervical， and shoulder region (the "coat-hanger headache")，
Coat-hanger headache -most likely due to neck muscle ischemia
Most common purpose of Lumbar puncture is in suspected -
Most common purpose is in suspected meningitis, since there is no other reliable tool with which meningitis, a life-threatening but highly treatable condition, can be excluded.
