Studies from the USA suggest that rates of pediatric bipolar disorder have increased since the mid-90s, but no study outside the USA has been published on the rates of pediatric bipolar disorder. Further, it is unclear whether an increase in rates reflects a true increase in the illness or more diagnostic attention. Using nationwide registers of all inpatients and outpatients contacts to all ps...

Between 1980 and 1995, the total number of active cases of tuberculosis (TB) in Canada declined steadily, from 2762 to 1930; the corresponding rates per 100 000 population were 11.2 and 6.5. During the same period, the number of cases of primary TB among children younger than 15 years remained disturbingly similar: 145 cases in 1980 and 156 in 1995. The rates were higher for those under 4 years...

Between 1985 and 1998, 12,331 patients were included in the general neonatal ultrasound hip screening programme for developmental dysplasia of the hip (DDH). Patients who needed treatment (604) were compared with a second group of 73 unscreened children treated conservatively and surgically for DDH. The incidence of Graf sonographic hip types IIc to IV varied throughout the observation period. ...

OBJECTIVES To present the incidence of vestibular schwannoma (VS) in Denmark, compare the incidence with that of previous periods, and discuss the real incidence of VS. DESIGN, SETTING, AND PATIENTS Prospective registration of all diagnosed VS in Denmark, with a population of 5.1 to 5.2 million, during the 6 years from January 1996 through December 2001. Incidence in this period was compared ...

BACKGROUND Cancer incidence and mortality rates have decreased over the last few decades, yet not all groups have benefited equally from these successes. This has resulted in increased disparities in cancer burden among various population groups. OBJECTIVE This study examined trends in absolute and relative disparities in overall cancer incidence and mortality rates between African American a...

The retreat of the Larsen B ice shelf, Antarctic Peninsula, and the collapse of its northern section are analyzed using satellite images acquired between January 1995 and May 2003. Over 1week during March 2002, after a period of steady retreat since 1995, 2300 km of the ice shelf broke up into many small icebergs. This rapid collapse occurred at the end of an exceptionally warm summer, and afte...

CONTEXT Medicare has a legislative mandate for quality assurance, but the effectiveness of its population-based quality improvement programs has been difficult to establish. OBJECTIVE To improve the quality of care for Medicare patients with acute myocardial infarction. DESIGN Quality improvement project with baseline measurement, feedback, remeasurement, and comparison samples. SETTING A...

OBJECTIVES To describe the effect of multidisciplinary care on survival in women treated for breast cancer. DESIGN Retrospective, comparative, non-randomised, interventional cohort study. SETTING NHS hospitals, health boards in the west of Scotland, UK. PARTICIPANTS 14,358 patients diagnosed with symptomatic invasive breast cancer between 1990 and 2000, residing in health board areas in t...

BACKGROUND Cervical cancer is the most common cancer experienced by women worldwide; however, screening techniques are very effective for reducing the risk of death. The national cervical cancer screening program was implemented in Taiwan in 1995. The objective of this study was to examine and provide evidence of the cervical cancer mortality trends for the periods before and after the screenin...
