This refers to the right posterior inferior cerebellar artery (PICA). PICA lesions present with lateral medullary syndrome characterized by crossed sensory deficits, vertigo, ataxia, ipsilateral Horner's syndrome, and nucleus ambiguus symptoms including dysphagia, hoarsness, and loss of gag reflex. +
This lesion portrays bitemporal hemianopia seen in large prolactinomas that abut the optic chiasm. +
This lesion portrays bitemporal hemianopia usually seen in large prolactinomas that compress the optic chiasm. It is unusual in cases with internal carotid artery lesions. +
Occipital lobe lesions usually cause homonymous hemianopia, although cases of quadrantanopia are also encountered. However, superior quadrantanopia is classically seen in temporal lobe lesions. +
This refers to neurotransmitter degradation. Acetylcholinersterase inhibitors act by inhibiting the breakdown of acetylcholine at the synaptic cleft. Cocaine has a different mechanism of action. +
Dependent personality disorder is characterized by a submissive personality often with very low self esteem. Patients usually have a constant need to be taken care of. +
A defense mechanism by which one avoids a certain difficult reality by denying it ever happened. This defense mechanism is not characteristic of borderline personality disorder. +

Creutzfeldt-Jakob disease (CJD) is a rapidly progressive form of dementia with characteristic myoclonus. It has a very poor prognosis with rapid progression. Pathologically, it is characterized by the replacement of normal protein by a protease-resistant isoform rich in beta-sheet structure. +
Because myasthenia gravis (MG) potentially causes respiratory depression due to involvement of the diaphragm, benzodiazepines are contraindicated in MG due to concerns of possible potentiation of respiratory depression. +
Meyer's loop is located in the temporal lobe and is a special region of the visual pathway. If lesioned, patients often complain of superior homonymous quadrantanopia. In the event of bilateral lesions, the expected visual loss would be vision loss of the superior half of the visual field. +
Meissner corpuscle is located in hairless skin, also called glabrous skin, in the dermal layer. It is made of encapsulated flat epithelial laminar cells. The afferent terminal fibers are found between these cells. Meissner corpuscle senses the fluttering touch and fine movement and signifies the velocity and duration of the signal with rapid adaptation. +
Contact dermatitis is an chemical-induced inflammation of the skin that directly damage the skin. It is commonly caused by bee sting, nickel, or rubber gloves. Clinical presentation, which is usually preceded by the exposure to the irritant, involves the appearance of pruritic papules and vesicles on an erythematous base. The lesion may become either hyper or hypopigmented with time. Topical corticosteroids are the mainstay of treatment. +
Incorrect. Antiphopholipid syndrome is an autoimmune disease in which "antiphospholipid antibodies" (anti-cardiolipin antibodies and lupus anticoagulant) react against proteins that bind to anionic phospholipids on plasma membranes. Common manifestation include: recurrent venous or arterial thrombosis and/or fetal loss. +
