Randomized Controlled Trial Multicenter Study Comparative Study Clinical Trial
An interim report of the effect of selegiline (L-deprenyl) on the progression of disability in early Parkinson's disease. The Parkinson Study Group.
The pathogenesis of Parkinson's disease (PD) has been linked to oxidative-mediated events including increased monoamine oxidase (MAO) and free-radical generation. We are investigating the ability of the MAO inhibitor, selegiline (deprenyl), and of the free-radical scavenger, tocopherol, to delay the onset of disability requiring levodopa therapy (primary end point) in patients with early PD. Eight hundred patients with early, untreated PD were enrolled in the multi-center placebo-controlled, double-blind clinical trial 'Deprenyl and Tocopherol Antioxidative Therapy of Parkinsonism (DATATOP)'. ⋯ We conclude from these preliminary results that selegiline (10 mg/day) delays the onset of disability associated with early, otherwise untreated PD. It remains unclear whether these benefits derive from mechanisms that are symptomatic (dopaminergic), protective (anti-neurotoxic), or both. The DATATOP study is ongoing to examine the long-term effects of selegiline and the independent and interactive effects of tocopherol.

Randomized Controlled Trial Multicenter Study Comparative Study Clinical Trial
A study to compare oral sumatriptan with oral aspirin plus oral metoclopramide in the acute treatment of migraine. The Oral Sumatriptan and Aspirin plus Metoclopramide Comparative Study Group.
In a double-blind, placebo-controlled study, the efficacy, safety and tolerability of 100 mg oral sumatriptan, given as a dispersible tablet, was compared with that of 900 mg oral aspirin plus 10 mg oral metoclopramide in the acute treatment of migraine. A total of 358 patients treated up to three migraine attacks within 3 months, recording clinical information on a diary card. In attack 1, headache relief after 2 h, defined as a reduction in severity from severe or moderate pain to mild or no pain, was recorded in 56% (74/133) of patients who took sumatriptan and 45% (62/138) of patients who took aspirin plus metoclopramide (p = 0.078). ⋯ Rescue medication was required by fewer patients treated with sumatriptan than by those who received aspirin plus metoclopramide (attack 1, 34 versus 56%, p less than 0.001; attack 2, 32 versus 51%, p = 0.001, and attack 3, 35 versus 54%, p = 0.001). Sumatriptan also produced a faster improvement and resolution of migraine attacks. Comparing the sumatriptan and aspirin plus metoclopramide treatment groups, complete resolution of the attack occurred within 6 h in 32 versus 19% (attack 1), 35 versus 23% (attack 2) and 32 versus 20% of patients (attack 3).(ABSTRACT TRUNCATED AT 250 WORDS)

Case Reports
Subarachnoid and intramedullary cysts secondary to epidural anesthesia for gynecological surgery.
Three women who received epidural anesthesia for gynecological surgery developed spinal arachnoiditis leading to subarachnoid cysts and cord cavitation. MRI was useful to show the subarachnoid and intramedullary cysts, as well as to monitor lesion extent and progress. ⋯ Although the 3rd patient had no treatment, there was spontaneous reduction in cavity size and clinical improvement. Careful handling of this procedure is urged to avoid such severe complications in young mothers.

The cheiro-oral syndrome is a well-known peculiar sensory disturbance seen around the corner of the mouth and in the palm of the hand on the same side. However, sensory disturbance around the corner of the mouth, in the palm of the hand and in the foot on the same side (cheiro-oral-pedal syndrome) has not been reported until now. We examined 2 cases of cheiro-oral-pedal syndrome; the lesion responsible was confirmed by magnetic resonance imaging to be in the medial lemniscus and in the ventral ascending tract of the trigeminal nerve.

Thrombotic and thromboembolic complications are the main causes of morbidity and mortality in patients with homocystinuria. However, it is unusual for thrombosis to be the single clinical feature leading to investigation for homocystinuria. ⋯ Treatment has been with methionine restriction and betaine. Homocystinuria should be considered in patients with unusual vascular lesions or premature thromboembolism.
