Interventions to reduce Staphylococcus aureus in the management of eczema.

Background: Staphylococcus aureus (S. aureus) can cause secondary infection in eczema, and may promote inflammation in eczema that does not look infected. There is no standard intervention to reduce S.

Canine olfactory detection of malignant melanoma.

Our patient is a 75-year-old man who presented after his pet dog licked persistently at an asymptomatic lesion behind his right ear. Examination revealed a nodular lesion in the postauricular sulcus. Histology confirmed malignant melanoma, which was subsequently excised.

Intravenous glomus tumour of the upper arm.

Glomus tumours are rare, benign tumours of the glomus body, most frequently located in the subungual region of digits, palms and soles, but they have been reported throughout the body. Our patient is a 65-year-old man who presented with a 3-year history of a very painful area on his left upper arm. The overlying skin was normal and there was no lesion to palpate, but the symptoms were very striking, warranting further investigation.

Recurrent pyogenic granuloma with satellitosis.

A 26-year-old woman was treated by curettage and cautery for a pyogenic granuloma on her left shoulder. This recurred 3 months later and was excised. After a further 5 months, she developed three vascular papules and one lobulated vascular lesion at the site.

Dermatological conditions in intensive care: a secondary analysis of the Intensive Care National Audit and Research Centre (ICNARC) Case Mix Programme database.

Introduction: Dermatology is usually thought of as an outpatient specialty with low mortality, however some skin conditions require intensive care. These conditions are relatively rare and hence are best studied using clinical databases or disease registries. We interrogated a large, high-quality clinical database from a national audit of adult intensive care units (ICUs), with the aim of identifying and characterising patients with dermatological conditions requiring admission to ICU.

Thyroid hormone receptor beta1 in normal colon and colorectal cancer-association with differentiation, polypoid growth type and K-ras mutations.

The precursors for colorectal cancer include polypoid (conventional), flat and serrated adenomas. Polypoid growth in polypoid adenomas and serrated adenomas is associated with K-ras mutations. The regulation of polypoid or nonpolypoid growth is not well known, but could be related to trophic stimuli, such as thyroid hormones.
