AIMS/HYPOTHESIS Low plasma vitamin D concentrations may promote the development of type 1 diabetes. To test this hypothesis, we measured plasma 25-hydroxyvitamin D (25OHD) in young adults with type 1 diabetes. METHODS The nationwide Diabetes Incidence Study in Sweden (DISS) covers 15- to 34-year-old people with newly diagnosed diabetes. Blood samples at(More)

Records and images of 99 consecutive percutaneous coaxial cutting needle lung biopsy procedures performed on 85 patients were reviewed retrospectively. Fifty-seven and 42 procedures had(More)
We evaluated the results of short-segment pedicle screw instrumentation in 54 patients with unstable thoracolumbar fractures. Follow-up averaged 25 months (range, 11 to 36 months); 42 patients completed the study. Kyphosis was corrected by an average of 7 degrees at surgery and loss of correction averaged 5 degrees at the end of follow-up. On computed(More)
A retrospective study of 36 patients with primary retroperitoneal sarcomas treated at The Norwegian Radium Hospital is presented. The median age at presentation was 57 years.

Two cases of congenital anomalies, one cyst and one sinus, presenting in the suprasternal notch are reported. No communication with deeper structures was found at surgery, and histology was compatible with previous descriptions of subcutaneous bronchogenic cysts. The literature is reviewed, and the similarity between these lesions and many cases of(More)
Orchiectomy was performed in 16 patients because of progression of prostatic cancer despite adequate medical castration with goserelin (Zoladex, ICI) over a mean period of 17.6 months. Severe tubular atrophy was seen in the testes. The Leydig cells also showed signs of atrophy, a fact that may indicate a direct effect of goserelin on these cells. In 1(More)
