Antitumor necrosis factor alpha (anti-TNFα) agents have substantially altered the management of inflammatory bowel diseases (IBD). Their benefits must however be weighed against increased risks for infections, lymphoma, and possibly other malignancies. We report on a 27-year-old man, with a six-year history of ulcerative colitis maintained on mesalamine suppositories, presenting with clinical, radiographic and biopsy evidence of an acute colitis flare. Due to the refractory nature of his disease, infliximab was started, resulting in induction of remission within six weeks. Three months after the first dose of infliximab, the patient was diagnosed with a testicular mixed germ cell tumor requiring orchiectomy. Four cases of testicular cancer development among patients using anti-TNFα agents have been identified. Given the prevalence of IBD in young men and recent suggestions for "top-down therapy," testicular cancer as a potential complication of anti-TNFα agents should be further explored on a population basis.

Aims: To study differences in cardiovascular prevention and hypertension management in primary care in men and women, with comparisons between public and privately operated primary health care (PHC).

Methods: We used register data from Region Stockholm on collected prescribed medication and registered diagnoses, to identify patients aged 30 years and above with hypertension. Age-adjusted logistic regression was used to calculate odds ratios (ORs) with 99% confidence intervals (99% CIs) using public PHC centers as referents.
