The Usefulness of 0.2% Topical Nitroglycerin for Chondrodermatitis Nodularis Helicis.

Background And Objective: Chondrodermatitis nodularis helicis (CNH) is a painful idiopathic degenerative condition involving the skin and cartilage of the helix or antihelix of the ear. Topical nitroglycerin 2% is a relatively recent treatment option for CNH that has produced good results, although with adverse effects (17% of cases). The use of a lower concentration would probably achieve similar results with fewer adverse effects.

A survey of culturable aerobic and anaerobic marine bacteria in de novo biofilm formation on natural substrates in St. Andrews Bay, Scotland.

This study reports a novel study of marine biofilm formation comprising aerobic and anaerobic bacteria. Samples of quartz and feldspar, minerals commonly found on the earth, were suspended 5 m deep in the North Sea off the east coast of St. Andrews, Scotland for 5 weeks.

[Clinical follow-up and presence of visceral tumors in 12 patients with sebaceous gland tumors].

Background: Sebaceous gland tumors are a rare type of neoplasm. In some cases they have been associated with visceral tumors in patients with Muir-Torre syndrome, a hereditary form of nonpolyposis colorectal cancer. The aim of this study was to review the diagnosis and follow-up of a series of patients with sebaceous gland tumors to assess how many met the criteria for Muir-Torre syndrome.
