Molluscum contagiosum virus infection.

Molluscum contagiosum virus is an important human skin pathogen: it can cause disfigurement and suffering in children, in adults it is less common and often sexually transmitted. Extensive and persistent skin infection with the virus can indicate underlying immunodeficiency. Traditional ablative therapies have not been compared directly with newer immune-modulating and specific antiviral therapies.

Vitiligo: concise evidence based guidelines on diagnosis and management.

Vitiligo is a common disease that causes a great degree of psychological distress. In its classical forms it is easily recognised and diagnosed. This review provides an evidence based outline of the management of vitiligo, particularly with the non-specialist in mind.

Eye protection for ultraviolet B phototherapy and psoralen ultraviolet A patients.

Background/purpose: We tested eye protection used for phototherapy patients. The study also established current practice concerning eye protection in a sample of UK phototherapy units.

Methods: The ultraviolet (UV) transmission spectra of 30 'UV protective' contact lenses were measured at 5 nm intervals between 290 and 400 nm.

Gene dosage analysis identifies large deletions of the FECH gene in 10% of families with erythropoietic protoporphyria.

Erythropoietic protoporphyria (EPP) is an inherited cutaneous porphyria characterized by partial deficiency of ferrochelatase (FECH), accumulation of protoporphyrin IX in erythrocytes, skin, and liver, and acute photosensitivity. Genetic counseling in EPP requires identification of FECH mutations, but current sequencing-based procedures fail to detect mutations in about one in six families. We have used gene dosage analysis by quantitative PCR to identify large deletions of the FECH gene in 19 (58%) of 33 unrelated UK patients with EPP in whom mutations could not be detected by sequencing.

Retrospective assessment of PASI 50 and PASI 75 attainment with a calcipotriol/betamethasone dipropionate ointment.

Background: The US National Psoriasis Foundation recently recommended that PASI 50 and PASI 75 response rates be used in clinical trials to enable comparisons across studies of different psoriasis therapies. To date, these response rates have not been reported for the two-compound ointment containing calcipotriol and betamethasone dipropionate (Daivobet/Dovobet; LEO Pharma, Ballerup, Denmark). Further, in order to compare Daivobet with other therapeutics recently presented to the European regulatory authorities and the FDA, comparison with the biologicals, efalizumab, etanercept and alefacept, were also made.
