question:
To study the long-term effects of selegiline in monotherapy and in combination with levodopa in the early phase of Parkinson disease (PD).', "One hundred fifty-seven de novo PD patients were randomized in a double-blind, placebo-controlled study of 7 years' duration. In the monotherapy part, selegiline significantly delayed the initiation of levodopa therapy vs placebo. The authors now report the results from the combination part of the study, in which 140 patients received selegiline or placebo in addition to individually tailored levodopa therapy.", 'Compared with placebo, selegiline slowed the progression of disease disability as measured by the Unified Parkinson Disease Rating Scale (UPDRS) total score (p = 0.003) or by motor (p = 0.002) and Activities of Daily Living (p = 0.0002) subscores. After 5 years in combination therapy, the mean difference in the UPDRS total score was nearly 10 points, with patients receiving placebo having 35% higher scores. Simultaneously, patients receiving placebo needed progressively higher doses of levodopa than patients receiving selegiline; after 5 years, the mean dosage of levodopa was 19% higher with placebo than with selegiline (p = 0.0002). Considering the entire (monotherapy and combination therapy) 7-year study time, there was a trend for selegiline to delay the start of wearing-off fluctuations (hazard ratio 0.55, p = 0.08). In both phases of the study, selegiline was safe and well tolerated.
answer:
Does selegiline slow the progression of the symptoms of Parkinson disease?


question:
Guillotine below-knee amputation (BKA) for wet gangrene is an unfortunate complication of poorly controlled diabetes. We examined risk factors associated with wound complications after amputation formalization in this patient population.', 'Retrospective data over a 4-year period were collected for patients undergoing guillotine BKA for wet gangrene followed by staged formalization. Patients with abnormal distal pulses underwent evaluation before formalization to stratify for peripheral arterial disease (PAD). Those patients with palpable pulses and no known PAD went to formalization without further investigation. Poor operative candidates underwent delayed formalization to allow for preoperative optimization. Patient history, interval between surgeries, pathology, and preformalization laboratories were tested for significance. Primary outcome was postformalization wound complication.', 'Fifty-six amputations in 55 patients met inclusion criteria. Wound complications after formalization occurred in 18 cases, all BKAs (32%). A history of PAD was present in 19 patients (34.5%). On pathology, 23 patients (41%) had small-vessel atherosclerosis or arteriosclerosis. There was no association between wound complications and history of PAD (P = 0.4), preformalization albumin (P = 0.09), glucose (P = 0.9), white blood cell count (P = 0.4), or delayed versus expedited formalization (P = 0.8). Only the presence of microvascular disease on formal pathology was predictive of wound complications (P = 0.03). There was no association between microvascular disease on pathology and a history of PAD (P = 0.07).
answer:
Is unrecognized arteriosclerosis associated with wound complications after below-knee amputation?


question:
The aim of this study is to establish follow-up protocols for adult patients with common variable immunodeficiency (CVID) in a recently founded adult immunology clinic in the Central Anatolia Region of Turkey, where a clinical immunology center for adults was not available previously.', 'A total of 25 patients with CVID aged 18 years and older were included in this study. The file format consisted of 13 pages and was developed for the purpose of the study. Separate sections were designated for identity information, medical history, disease course, previous and current laboratory and imaging studies, follow-up plans, detection and management of complications/comorbidities, and treatment results.', 'The mean age of the patients was 36.6 ± 13.4 years. The delay in diagnosis was 107 ± 95.6 months. In 92% of patients, initial symptoms resulting in admission to healthcare facilities were infections. Seventeen of 25 patients (68%) had bronchiectasis at the beginning of follow-up.
answer:

Does common variable immunodeficiency in adults require reserved protocols for long-term follow-up?
