Concomitant dysregulation of androgen secretion and dysfunction of adipose tissue induced insulin resistance

Hyperandrogenism and hyperinsulinemia have resulted from dysfunction of the theca cell of the ovary and adipose tissue and each one potentiates the other in patients with androgen excess disorders e.g., polycystic ovary disease and idiopathic hirsutism. Possible external and/or internal triggers can produce such cellular dysfunction. There is evidence that sodium valproate acts as a trigger of cellular dysfunction and produces both hyperinsulinemia and hyperandrogenism. Therefore, the elimination of these triggers can help the patients to recover from hyperinsulinemia, insulin resistance and hyperandrogenism.     

The Nobel Prize and otolaryngology: ‘Papa Gunnar’s’ promotion of his peers Gustav Killian and Themistocles Gluck

Objectives: This study is part of a larger project investigating the enactment of excellence in medicine, with a focus on the Nobel Prize. It takes a closer look at two promising candidates for the Prize in the 1920s and 1930s, Gustav Killian and Themistocles Gluck, and aims at reconstructing their Nobel careers as well as taking Gunnar Holmgren’s role as a nominator and evaluator behind the curtains into account.

Method: Besides the files collected at the Nobel Archive, the paper is based on a review of scientific publications and ergo-biographical sketches.

Results: An analysis of Nobel Prize nominations and evaluations offer a unique perspective to study aspects of the history of otolaryngology.

Conclusion: Using original files in the archive of the Nobel committee for physiology or medicine in Sweden, this historical vignette explores judgments of scientific innovation and performance in the history of otolaryngology during the first half of the 20th century. This study shows that Gunnar Holmgren, the founder of Acta Oto-Laryngologica in 1918, repeatedly put forward scholars within the field as prime contenders for the award.     

Fluorescence in situ hybridization in diagnostic cytology

Fluorescence in situ hybridization (FISH) is a technique that uses fluorescently labeled DNA probes to detect chromosomal alterations in cells. FISH can detect various types of cytogenetic alterations including aneusomy (ie, abnormalities of chromosome copy number), duplication, amplification, deletion, and translocation. Because tumor cells generally contain chromosomal alterations, FISH is able to detect cells that have chromosomal abnormalities consistent with neoplasia in exfoliative and aspiration cytology specimens. This review will discuss the utility of FISH for the detection of bladder, lung, pancreatobiliary, and esophageal carcinoma in cytologic specimens.     

Successful renal transplantation in a family with a novel mutation in COL4A3 gene and autosomal recessive Alport syndrome

Alport syndrome (AS) is an inherited disorder of basement membranes caused by mutations affecting specific proteins of the type IV collagen family, presenting with nephropathy and extrarenal manifestations such as sensorineural deafness and ocular anomalies. Ten percentage to 15% of the patients with AS have autosomal recessive (ARAS) due to mutation in either COL4A3 or COL4A4 gene. We report a novel mutation in the COL4A3 gene in an Indian family with ARAS. The above‐mentioned genetic anomaly was a missense variation in exon 26 of the COL4A3 gene (chr2:228137797G>A; c.1891G>A) that resulted in the amino acid substitution of Arginine for Glycine at codon 631 (p.Gly631Arg) that was present in the heterozygous state in the asymptomatic parents and homozygous state in the male offspring who presented with early‐onset end‐stage renal disease, lenticonus and hearing loss. The patient (male offspring) underwent successful renal transplantation with his mother as a donor.     

Etablierung von Urologischen Universitätskliniken in NRW

The foundation of university departments of urology in postwar East and West Germany faced some opposition by some university professors of surgery who wanted to preserve the unity of their discipline. In North Rhine–Westphalia, heads of municipal hospitals or senior members of university hospitals’ staff often received the first chaired professorships of urology.
