    Notes: Abstract: The treatment of patients with metastasizing melanoma, still one of the most deadly diseases in modern medicine, ranks among the greatest challenges that a clinician has to face. Metastatic melanoma also is one of the most profound sources of clinical frustration, since it provides far more ultimately defeating experiences than clinical victories. At the same time, the fascinating biology of melanoma has invited the study of this neuroectodermal tumor as a model system for dissecting many of the key problems of modern oncology, ranging from molecular oncogenesis via the controls of tumor proliferation, apoptosis, invasion, metastasis, and angiogenesis to tumor immunosurveillance and tumor drug resistance. Together with the dire need to develop more effective treatment modalities for improving both life expectancy and quality of life of affected patients, this has made metastatic melanoma a favorite model for the exploration of innovative strategies for tumor management. Encouragingly, many of these have already generated very promising results in animal models. However, this impressive level of research progress in conquering melanoma in the animal room contrasts rather pitifully with the actual progress made on the ward. This CONTROVERSIES feature, therefore, critically and soberly reviews the state of the art of treating metastatic melanoma today (distinguishing between nodal and distant metastases), and sharply defines unresolved or comparatively neglected key problems. In addition, this feature highlights several novel, provocative, hitherto underappreciated, yet potentially promising treatment approaches that deserve systematic exploration. Hopefully, this will offer further inspiration for the design and pursuit of innovative anti-melanoma strategies off-the-beaten-track.

    Notes: Background  Werner syndrome (WS) is a rare autosomal recessive progeroid disorder caused by mutations of the WRN gene encoding a protein of the RecQ-type family of DNA helicases.Objectives  To develop a rapid and simple reverse transcription-polymerase chain reaction (RT-PCR) strategy for mutation analysis of the WRN gene, to identify pathogenic mutations in a German patient with WS and to determine the effects of the pathogenic mutations on WRN mRNA stability.Methods  Allele-specific RT-PCR, semiquantitative RT-PCR, DNA sequencing.Results  We describe a novel and rapid RT-PCR-based method for mutation analysis in WS and report a German patient with WS carrying a previously reported (1396delA) as well as a novel nonsense mutation (2334delAC) of the WRN gene. By semiquantitative RT-PCR analysis we demonstrate that this compound heterozygous genotype leads to WRN transcript decay.Conclusions  In previous studies WS was primarily attributed to a loss of function of stable truncated WRN gene products. Our findings indicate that mutations can also lead to markedly decreased WRN transcript stability.

    Notes: Indications for in vitro fertilization (IVF) have been cautiously extended over the years. IVF is usually considered to be a technically complex method with only minimal side-effects. We report the case of a woman who developed an anaphylactic reaction during IVF immediately after the embryo transfer.
