Infections of the genital tract are considered common causes of male fertility disorders, with a prevalence of 6-10%. Most of the affected men are asymptomatic. The diagnostic evaluation is based mainly on laboratory testing. Inconsistent diagnostic criteria have been applied to date, and this may explain the controversial debate about the role of infection and inflammation in the genital tract as a cause of infertility. The risk of an irreversible fertility disorder should not be underestimated. ⋯ Any suspicion of an infectious or inflammatory disease in the male genital tract should prompt a systematic diagnostic evaluation and appropriate treatment. For patients with obstructive azoospermia, the etiology and site of the obstruction determine the surgical approach to be taken. In the near future, the elucidation of underlying pathophysiological mechanisms and the identification of suitable biomarkers may enable new strategies for conservative treatment.

The incidence of inflammatory bowel disease (IBD) in childhood and adolescence is 5-11 cases per 100 000 persons per year, corresponding to a new diagnosis of IBD in 800-1470 patients in Germany each year. ⋯ Children and adolescents with IBD or suspected IBD should be cared for by pediatric gastroenterologists in a center where such care is provided. Individualized treatment with multidisciplinary, family-oriented longterm care is particularly important. Drug trials in children and adolescents are needed so that the off-label use of drugs to patients in this age group can be reduced.

Red eye can arise as a manifestation of many different systemic and ophthalmological diseases. The physician whom the patient first consults for this problem is often not an ophthalmologist. A correct assessment of the urgency of the situation is vitally important for the planning of further diagnostic evaluation and treatment. ⋯ The differential diagnosis of red eye can be narrowed down rapidly with simple baseline tests and targeted questioning. Patients with ocular emergencies should be referred to an ophthalmologist at once, as should all patients whose diagnosis is in doubt.

Tracheotomies are frequently performed on ventilated patients in intensive care and sometimes lead to fatal complications. In this article, we discuss the causes and frequency of death associated with open surgical tracheotomy (OST) and percutaneous dilatational tracheotomy (PDT) on the basis of a review of the pertinent literature. ⋯ Bias in the data cannot be excluded, as these were not epidemiologic data and the documentation was found to be incomplete. The likelihood of a fatal complication seems to be the same with both tracheotomy techniques as far as can be determined from the available evidence. Tracheotomy-related deaths can be avoided in several ways: by thorough training under the leadership of experienced physicians, by the use of the World Health Organization's Surgical Safety Checklist regardless of where the tracheotomy is performed, and by the continuous vigilance of nursing staff.

In 2013, the German Standing Committee on Vaccination (Ständige Impfkommission, STIKO) recommended rotavirus (RV) vaccination for all infants while stating that this mildly increased the risk of intussusception, a potentially life-threatening event. Since this recommendation was issued, multiple observational studies on this topic designed as self-controlled case series (SCCS) have been published. The SCCS design is particularly suitable for the study of rare adverse effects of medications. ⋯ RV vaccination is associated with a markedly elevated RR and a mildly elevated AR for intussusception 1-7 days after the first dose. Physicians should begin the series of vaccinations at age 6-12 weeks, as recommended by the STIKO, because the risk of intussusception is higher afterward. Current health insurance company claim data indicate that 11.2% of infants are still receiving the first dose of the vaccine at ages above 3 months. The parents of vaccinated children should be informed about the possible signs of intussusception (colicky pain, bilious vomiting, and red "currant jelly" stool).
