Palaeoecology involves analysis of fossil and sub-fossil evidence preserved within sediments to understand past species distributions, habitats and ecosystems. However, while palaeoecological research is sometimes made relevant to contemporary ecology, especially to advance understanding of biogeographical theory or in…

OBJECTIVE: The spleen is the most frequently involved organ in abdominal blunt traumas. In the last decade the treatment has changed from an exclusive surgical approach to a conservative approach. We report our experience in the last twenty years. METHODS: Between 1983-2003, 54 patients with blunt abdominal traumas an…

BACKGROUND: Despite important advances in the field of bariatric surgery over the last 40 years, no single operation has clearly emerged as the optimum procedure. Over the last decade, however, attention has focused on vertical banded gastroplasty (VBG) and Roux-en-Y gastric bypass (RGB). PATIENTS AND METHODS: We comp…

This review outlines the discovery and development of a novel series of 1-[4-2- aminoethoxy)phenylcarbonyl]-3,5-bis-(benzylidene)-4-piperidones (5-8) as potential drug candidates over the last 15 years in our laboratory. Many of these compounds demonstrate excellent cytotoxic properties and are often more potent than c…

PURPOSE: Management of the postpubertal cryptorchid testis depends on patient age at presentation. Based on the belief that the risk of death from surgery first exceeds the risk of death from testis cancer at age 32 years patients younger than 32 years are advised to undergo orchiectomy, while those older than 32 years…

PURPOSE: The aim of this study was to evaluate the effects of definitive arthrodesis on frontal and sagittal spine balance in EOS patients treated with MCGR, as well as the complications associated with this procedure and the outcome at last follow-up. METHODS: This was a multicentre study in 10 French centres. All pa…

Acute hepatitis A is a self-limited liver inflammation caused by hepatitis A virus (HAV) infection.

In this retrospective cohort study (n = 479), the proportion of women with premature ovarian insufficiency (POI) who conceived was assessed, the reproductive characteristics of women with POI who had previously been pregnant or had never been pregnant compared, and the interval between last conception and the menopause…

BACKGROUND AND AIMS: There are certain areas of uncertainty regarding the best therapeutic approach in patients diagnosed with Wilson Disease (WD). Our aim was to assess treatment response to different therapies in a cohort of WD patients followed in a single center. MATERIAL AND METHODS: This is an observational, des…

Nowadays, about the half of Swiss women die after their 84th birthday. This unprecedented proportion of the population reaching an old age, or even a very old age (25% of women die after 89 years, and 5% after 95 years) is a novel aspect of human demographics, and represents the very last stage of the epidemiological t…

UNLABELLED: The origin of hepatitis B virus (HBV) infection in humans and other primates remains largely unresolved. Understanding the origin of HBV is crucial because it provides a framework for studying the burden, and subsequently the evolution, of HBV pathogenicity with respect to changes in human population size a…

SETTING: Nationwide random sample survey for tuberculosis in 1990. OBJECTIVE: To investigate the prevalence of tuberculosis infection, morbidity and drug resistance and BCG coverage, and to compare the findings with those of the previous 5 surveys. DESIGN: The following investigations were performed: tuberculin test,…

Liver transplantation (LT) has been established as the most effective treatment modality for end-stage liver disease over the last few decades. Currently, patient and graft survival after LT are excellent, with 1- and 5-year survival of 90% and 80%, respectively. However, the timing of referral to LT is crucial for imp…

The aim of this study was to assess the clinical and radiological outcome of the cementless-system (CLS) femoral component designed by Spotorno with a taper design. Ninety-four patients (107 hips) were operated on from January 1987 to December 1988. The female/male ratio was 2/1, the mean age was 51 years (range 20-77…

The aim of this study was to estimate the prevalence of macroscopic reproductive tract abnormalities in a sample of female cattle in the UK. To our knowledge, this type of post-mortem survey has not been conducted in the UK since the 1970s. Over the last 40 years significant changes have occurred with respect to manage…

BACKGROUND: This systematic review evaluates the efficacy and safety of elective primary total elbow arthroplasty (TEA).
