BACKGROUND Selected groups of patients with bipolar and unipolar disorder have an increased mortality rate from suicide and natural causes of death. However, there has been no population-based study of mortality of patients followed up from the onset of the illness. METHODS All patients with a hospital diagnosis of bipolar (n = 15 386) or unipolar (n = 39(More)
A study of mortality for all patients with a first hospital diagnosis of schizophrenia in Stockholm County, Sweden, during 1973 to 1995 was performed, by linking the in-patient register with the national cause-of-death register. Overall and cause-specific standardized mortality ratios (SMR) were calculated by 5-year age classes and 5-year calendar time(More)
CONTEXT Postpartum psychosis occurs in 1 to 2 cases per 1000 live births. Most studies have not distinguished postpartum psychosis from bipolar disorder or the proportion of the incidence attributable to prepregnancy psychiatric morbidity. OBJECTIVE To determine the incidence of postpartum psychosis and bipolar disorder attributable to previous(More)
Although mortality in patients with schizophrenia is two to three times higher than that in the general population, little is known about time trends in mortality rates. 1–3 We aimed to assess mortality over time after a first admission to hospital with schizophre-nia. In those patients who died, the cause of death was categorised as natural,(More)
that might predispose to retropalatal upper airway narrowing. Since facial structure is at least partly inherited, this may provide the familial link in the sudden infant death syndrome, although larger studies are required to confirm these findings. These results also provide a further link between the sudden infant death and obstructive sleep(More)
BACKGROUND Obstetrical complications, based on parental recall, have been reported to be associated with development of anorexia nervosa. We used prospectively collected data about pregnancy and perinatal factors to examine the subsequent development of anorexia nervosa. METHODS This population-based, case-control study was nested in cohorts defined by(More)
BACKGROUND The risk of Guillain-Barré syndrome (GBS) following the United States' 1976 swine flu vaccination campaign in the USA led to enhanced active surveillance during the pandemic influenza (A(H1N1)pdm09) immunization campaign. This study aimed to estimate the risk of GBS following influenza A(H1N1)pdm09 vaccination. METHODS A self-controlled case(More)
Several studies have reported decreasing time trends in first diagnosed schizophrenia patients. The aim of this study was to analyze time trends for first admissions with a diagnosis of schizophrenia or a diagnosis of either schizophrenia or paranoid psychosis during 1978-1994 in Stockholm County, Sweden, with a population of around 1.8million.

Common warts could indicate cervical cancer susceptibility, as both are caused by human papillomavirus (HPV). Eczema was also investigated, as atopic eczema has been negatively associated with warts, but non-atopic eczema may be associated with compromised host defences, as observed in patients with HIV, suggesting increased susceptibility to HPV infection(More)
Legionnaires' disease (LD) is caused by the inhalation of aerosols containing Legionella, a Gram-negative bacteria. Previous national- or regional-level studies have suggested an impact of climate on LD incidence. The objective of this study was to investigate the effect of temperature, rainfall, and atmospheric pressure on short-term variations in LD(More)
