The effects of the concomitant administration of N-n-propyl norapomorphine (NPA) and levodopa, with and without carbidopa, were studied in 12 patients with unsatisfactory symptom control. Double-blind evaluation of the effects of NPA with suboptimal doses of levodopa or levodopa plus carbidopa (Sinemet) showed a mean overall improvement of 44% (20% to 74%)… (More)
High concentrations of the dopaminergic drug levodopa (L-dopa, L-3,4-dihydroxphenylalanine) administered to mice in their diet affected fertility to a moderate degree and prolonged the mean life-span by a maximum of 50 percent.
The effects of seizures on the cerebral and peripheral metabolism of essential metals were studied in mice. Acute and chronic seizures were produced either by electroshock (ES) or by a systemic convulsant. Organ and subcellular distribution of 54Mn and 65Zn were determined prior to and at different intervals after seizure cessation. In mice shocked for 21… (More)
In 19 patients with Parkinson disease, we studied the relationship of the therapeutic effect of levodopa, or dyskinesia, to the plasma content of DOPA and growth hormone (GH). Those with stable responses to levodopa, individually or as a group, showed stable and lower plasma DOPA levels than those with unstable symptomatic responses. These results show that… (More)
Diphenylhydantoin (DPH) diminished the therapeutic effects of levodopa both in patients with parkinsonism and in patients with chronic manganese poisoning, as well as the levodopa-dependent dyskinesia for which the former were selected. In patients with Huntington chorea, it enhanced chorea and mental agitation and, thus, failed to conform with the… (More)
BACKGROUND There is limited evidence that Merkel cell carcinoma (MCC) arising from a nodal basin without evidence of a primary cutaneous (PC) site has better prognosis. We present our experience at 2 tertiary care referral centers with stage III MCC with and without a PC site. METHODS Fifty stage III MCC patients were identified between 1996 and 2011.… (More)
BACKGROUND In the 1990s, partial stomach-partitioning gastrojejunostomy (PSPG) was introduced. Benefits of this method are that it preferentially shunts food away from the obstructed duodenum or pylorus, thus reducing reflex emesis. METHODS A retrospective review of patients undergoing PSPG for malignant obstruction from 1999 to 2011 was performed.… (More)
