Question: Abstract: Transient global amnesia is an unusual form of the amnestic syndrome in that it is completely reversible in most patients. The etiology of transient global amnesia is poorly understood, although involvement of the medial temporal lobe is most likely. The literature suggests that once an underlying structural lesion has been ruled out, cases can be divided into three groups: patients with a past history of migraine headaches, those who have no obvious underlying precipitating factors, and those with associated neurologic deficits during a spell and risk factors for cerebrovascular disease. Patients in the first group tend to have attacks at an earlier age and to have an increased recurrence rate but, like those in the second group, have a good prognosis. Patients in the third group often have onset later in life, and as many as 10% may have a stroke or dementia. Whether or not this is a higher incidence than should be expected in persons of this age group has not been determined. Although sophisticated testing may show persistence of the memory defect, most patients eventually recover completely.

Question: Abstract: The effectiveness of neostigmine 0.07 mg kg-1 and edrophonium 0.8 mg kg-1 as antagonists of profound neuromuscular blockade induced by vecuronium 0.1 mg kg-1 or atracurium 0.5 mg kg-1 was studied in 59 healthy patients. The antagonists were administered 5 min after total ablation of the twitch response and the end-point of recovery was a train-of-four ratio of 70%. In 30 patients given vecuronium the mean time to reach this point (duration TOF70) was 66.7 min in the control group (no antagonist), 43.5 min in the group given neostigmine and 59.8 min in the group given edrophonium. The duration TOF70 was shorter in the neostigmine group than in the control (P less than 0.01) and edrophonium (P less than 0.01) groups. The duration TOF70 did not differ from control in the edrophonium group. In 29 patients given atracurium, the durations TOF70 were 66.4, 44.1 and 54.9 min in the control, neostigmine and edrophonium groups, respectively. The durations TOF70 in the neostigmine (P less than 0.01) and edrophonium (P less than 0.01), groups were shorter than control. The duration TOF70 of the neostigmine group was shorter than in the edrophonium group (P less than 0.01). These results show that profound neuromuscular blockade cannot be rapidly antagonized by either of these two agents, but if reversal is required under these circumstances, neostigmine would be the more effective drug.

Question: Abstract: Any fall in the elderly may signal impending major illness. Falls may be caused by any acute or chronic illness that causes weakness or dizziness. MI, stroke, or GI bleeding may well present with falls. A fall can be the first sign of urinary tract, respiratory, or gallbladder infection. Avoid open-ended questions, such as "What happened?" Patients often state they slipped or tripped--possibly not the true reason for the fall. Direct questions about symptoms ("Did you have difficulty in walking?" or "Did you feel dizzy?") elicit more specific information.
