Pregnancy causes a number of physiological alterations in thyroid hormone metabolism that need to be distinguished from the pathophysiological states of thyroid dysfunction. Both hypothyroidism and thyrotoxicosis may impair the course of pregnancy and may negatively affect the fetus. In particular, maternal hypothyroidism may lead to irreparable and detrimental deficits in the neurocognitive development of the fetus. ⋯ Hashimoto's thyroiditis is associated with impaired fertility and miscarriage, and may first manifest in pregnancy due to the increased thyroid hormone requirement. Graves' disease often shows a characteristic course in pregnancy with amelioration of thyrotoxicosis in the second half of pregnancy and exacerbation after delivery. In addition transplacental passage of maternal TSH receptor antibodies may lead to thyrotoxicosis in the fetus and/or newborn.

Invasive fungal infections have gained importance in many areas of clinical medicine and represent a growing diagnostic and therapeutic challenge for clinicians. During the last decade, several new antifungals were introduced into routine therapy: two second-generation triazoles and the new class of echinocandins. ⋯ Consequently, they were integrated in recent therapeutic guidelines, often replacing former standard drugs as first-line options. The echinocandins (anidulafungin, caspofungin, micafungin) primarily have gained a central role in the treatment of invasive Candida infections, while the novel triazoles voriconazole and posaconazole established themselves as the current mainstays in therapy and prophylaxis of invasive fungal infections, particularly aspergillosis, in hemato-oncologic high-risk patients.

Influenza infections have important socio-economic consequences. Risk groups identified so far include small children and elderly adults with comorbidities. ⋯ For the latter other at risk groups were affected and a different clinical course has been documented. The focus of this article is to give an overview on the epidemiology, clinical characteristics, diagnosis and therapy of influenza infections.
