Predicting the effects of future global changes on species requires a better understanding of the ecological niche dynamics in response to climate; the large climatic fluctuations of the last 50,000 years can be used as a natural experiment to that aim. Here we test whether the realized niche of horse, aurochs, red dee…

We describe the clinical/haematological characteristics of 446 patients with hereditary spherocytosis diagnosed in the last 40 years in a reference centre. The frequency of splenectomy decreased over time (44% before 1990 to 7% in 2011-2020), notwithstanding a confirmed good efficacy. Age at splenectomy progressiv…

In 1994 the highest incidence of this disease was in the West region. Ten of the most critically ill patients were trea…

PURPOSE: Complication rates of up to 86.6% have been reported after creation of an ileal conduit. In contrast to others, we construct an antirefluxing isoperistaltic colonic for incontinent diversion in children. MATERIALS AND METHODS: Between 1968 and 1989 a colonic conduit was created in 105 patients up to age 20 ye…

Ninety-one patients with idiopathic scoliosis, who underwent posterior spinal fusion and instrumentation from January 1977 to December 1982, were reviewed.

This study describes epidemiologic trends in consumer product-related pediatric ocular injuries from 2010 to 2019. METHODS: This is a retrospective observational study utilizin…

AIMS: Cardiogenic shock (CS) is an ominous complication of ST-elevation myocardial infarction (STEMI), despite the recent widespread use of reperfusion and invasive management. The Ruti-STEMI-Shock registry analysed the prevalence of and 30-day and 1-year mortality rates in ST-elevation myocardial infarction (STEMI) co…

BACKGROUND: Pertussis is still frequently reported in Canada. In Alberta, pertussis incidence ranged from 1.8 to 20.5 cases per 100,000 persons for 2004-2015. Most cases occurred in those aged <15&#x202f;years. In Alberta, acellular formulations replaced whole-cell in 1997. We investigated pertussis vaccine effectivene…

5-Fluorouramcil has been the medicine of choice for systemic treatment of metastatic colonic cancer for the last 35 years. Objective positive results of this therapy were documented in 30% of the cases, it delayed the development of active disease by 4 months, and ensured a 6 month survival. Introduction of irinotecan,…

The definitive axes of the mouse embryo can be unequivocally identified in embryos dissected at 5.5 days of gestation. However, how and when are these axes established remains an open question. At pre-implantation stages, different approaches have been aimed at determining if events occurring in the zygote influence th…

We report a case of 48 years old women with a 8 years history of rheumatoid arthritis and severe articular deformation treated during the last 6 months by prednisone (5 mg daily) and chloroquine (200 mg daily), admitted in the emergency room because of syncope.

In 1986 every person consumed an average of 11.5 litres of pure alcohol (146.4 litres of beer, 23.3 litres of wine and 6.1 litres of spirits). The amount of the alcohol addicts must be estimated a…

PURPOSE: An arthroscopic partial meniscectomy (APM) for degenerative meniscus lesions and traumatic meniscus tears are two distinct entities and their long-term outcomes are rarely reported. The aim of this review was to compare the long-term (clinical and radiological) results of APM performed on stable knees for trau…

OBJECTIVES: Pulmonary parenchymal changes appear many years after the start of exposure to asbestos and their progression has been observed to continue many years after cessation of the exposure.
