About 40% of all cases involved poisoning by drugs. The most frequent fatal poisons were hypnotics. Among the serious cases reported to the Swiss Toxicol…

Child psychiatric epidemiology over the last 25 years is reviewed in terms of conceptual and methodological issues arising out of substantive findings. The Isle of Wight surveys undertaken in the mid-1960s are briefly described to establish a starting point, and progress since then is reviewed in terms of topics not or…

The West Antarctic Peninsula (WAP) is a hotspot of climate warming, evidencing glacier retreat and a decrease in the fast-ice duration. This study provides a > 30-y time-series (1987-2022) on annual and seasonal air temperatures in Potter Cove (Isla 25 de Mayo/King George Island). It investigates the interact…

BACKGROUND: According to studies from Guinea-Bissau and Senegal, live vaccines may reduce the female-male mortality ratio (MR) whereas inactivated vaccines increase this ratio. We used data from The Gambia to examine whether similar tendencies could be found in a different setting. SETTING: Forty villages in the Faraf…

Approximately one in four patients experiences nausea and/or vomiting in anticipation of a chemotherapy treatment by the time of their fourth treatment cycle. Anticipatory nausea and vomiting is a prevalent problem of clinical significance in the total management of chemotherapy side effects. While refractory to standa…

BACKGROUND: Outcome and treatment-associated morbidity analysis of trigone meningioma surgery. METHODS: We retrospectively assessed 27 neurosurgically treated patients (median age 63 years, range 15-84) between 1999 and 2019. The median preoperative Karnofsky Performance Scale (KPS) was 80 (range 20-100), and the majo…

OBJECTIVE: To evaluate the in vitro susceptibility and cross-resistance of gatifloxacin and moxifloxacin vs older fluoroquinolones among coagulase-negative staphylococci recovered from patients with clinical endophthalmitis.

The ureterovaginal fistulas resolved in all 7 patients in whom a self-retaining internal stent was placed in either a retrograde (5) or antegrade (2) mann…

The causes of disqualification in a volunteer blood donor population for a period of two years were analyzed. Of 138,436 prospective volunteer blood donors, 24,327 (17.6%) donors were disqualified. Phlebotomy was unsuccesful in 721 (0.5%) donors and blood was drawn from 113,388 (81.9%) eligible donors. The majority of…

5-HT1A receptor (5-HT1A-R) is a serotoninergic G-protein coupled receptor subtype which contributes to several physiological processes in both central nervous system and periphery. Despite being the first 5-HT-R identified, cloned and studied, it still represents a very attractive target in drug discovery and continues…

Coronary allograft vasculopathy (CAV) is a leading cause of allograft failure in pediatric heart transplant recipients. Percutaneous coronary intervention (PCI) is performed to manage atherosclerotic coronary artery disease. However, there is currently limited data regarding use and long-term benefit of PCI due to the…
