Twenty six adolescents with myelomeningocele have been followed from birth: they comprise the whole population born with myelomeningocele between 1964 and 1967 in one Swedish medical district. 18 have severe physical handicaps, and although there are equal numbers of males and females, more females have severe handicaps, 22 of the 26 have been educated in(More)
Family dynamics and social conditions were studied of 527 children with myelomeningocele aged four to 18 years from Denmark, Finland, Norway and Sweden; the control group was a representative sample of 7792 children of the same age-range and from the same countries. Information was obtained from postal questionnaires and from patients' charts. Overall,(More)
Oesophageal and gastric adenocarcinoma share an unexplained male predominance, which would be explained by the hypothesis that oestrogens are protective in this respect. We carried out a nested case-control study of hormone replacement therapy (HRT) among 299 women with oesophageal cancer, 313 with gastric cancer, and 3191 randomly selected control women,(More)
The male predominance of oesophageal adenocarcinoma might be explained by oestrogen protection in women. If true, female patients might have sex hormonal disturbances rendering impaired fertility. The influence of childbearing on the risk of oesophageal adenocarcinoma was investigated in a Swedish population-based case (n=63) -control (n=141) study.(More)
BACKGROUND Survival trends in oesophageal and gastric cancer need to be updated. A nationwide Swedish population-based study in 1961-2009 was based on registry data. METHODOLOGY/PRINCIPAL FINDINGS Relative survival rate, i.e. the ratio of the observed to the expected survival, adjusted for age, sex, and calendar period, and presented with 95% confidence(More)
BACKGROUND Cholangiocarcinomas are highly lethal tumours of the intrahepatic or extrahepatic biliary tract. The aetiology is largely unknown, and the potential roles of gallstones and gall bladder removal (cholecystectomy) need to be addressed in a large study with a long follow-up. METHODS A population-based nationwide Swedish cohort study was carried(More)
BACKGROUND The prevalence and role of human papillomavirus (HPV) in the aetiology of oesophageal squamous cell carcinoma is uncertain. Based on the presence of HPV in the oral cavity and its causal association with squamous cell carcinoma of the oropharynx, we hypothesised that HPV is more strongly associated with proximal than distal oesophageal squamous(More)
OBJECTIVE To evaluate a new and simpler strategy of antibiotic prophylaxis in percutaneous endoscopic gastrostomy (PEG). DESIGN Single centre, two arm, randomised, controlled, double blind clinical trial. SETTING Endoscopy unit in Karolinska University Hospital, Stockholm, Sweden, between 3 June 2005 and 31 October 2009. PARTICIPANTS 234 patients with(More)
A nationwide Swedish case-control study of 388 men and 63 women with adenocarcinoma of the oesophagus and gastro-oesophageal function and 676 men controls and 140 women investigated whether sex differences in aetiology contribute to male predominance. Compared with men, women seemed more vulnerable to reflux (odds ratio (OR)=4.6, 95% confidence interval(More)
