Merkel cell carcinoma: a review.

Merkel cell carcinoma (MCC) is a rare neuroendocrine tumor of unknown origin that usually presents in the elderly population. A novel polyomavirus has been associated with a large percentage of tumors. Immune response plays an important role in pathogenesis of MCC.

Current status of surgery in dermatology.

An article titled "Current issues in dermatologic office-based surgery" was published in the JAAD in October 1999 (volume 41, issue 4, pp. 624-634). The article was developed by the Joint American Academy of Dermatology/American Society for Dermatologic Surgery Liaison Committee.

The tower technique: a novel technique for the injection of hyaluronic acid fillers.

A number of injection techniques have been described for the placement of hyaluronic acid fillers. Such techniques include, but are not limited to, linear threading, depot, fanning, and layering. The tower technique for hyaluronic acid filler injection is a novel variation of the depot and layering techniques.

Hodgkin lymphoma presenting as generalized pruritus in an adolescent.

Pruritus is a common manifestation of Hodgkin lymphoma (HL), and given its high frequency, inclusion of itching as a B symptom of HL has been proposed. We present a 16-year-old adolescent boy with treatment-refractory eczema of 2 years' duration. Physical examination revealed a thin adolescent boy with widespread excoriations, but no eczematous or primary cutaneous lesions were identifiable.

Metabotropic glutamate receptor 2 and 3 gene expression in the human prefrontal cortex and mesencephalon in schizophrenia.

Group II metabotropic glutamate receptors (mGluR2 and mGluR3) are implicated in schizophrenia. We characterized mGluR2 and 3 mRNA in the human prefrontal cortex (PFC) and mesencephalon, and then compared cases with schizophrenia to matched controls. In the human brain, both receptors were expressed in the PFC and, unlike the rodent, in dopaminergic (DA) cell groups.

Advertising in dermatology journals: journals' and journal editors' policies, practices, and attitudes.

Background: Problems in some advertisements in medical journals, including dermatology journals, have been identified in various studies. Examples have included poorly supported claims, failure to balance claims of efficacy with potential adverse effects of a drug, and slogans that recommend prescribing a drug for groups of patients different from those assessed in a referenced study.

Objective: We sought to assess dermatology journals' and dermatology journal editors' policies, practices, and attitudes toward prescription-medicine advertising in dermatology journals.

Reducing the incidence of foot ulceration and amputation in diabetes.

Diabetes is a common disease that is associated with numerous complications, including foot ulceration and amputation. In diabetic patients, the incidence of foot ulcers ranges from 1.0% to 4.

Downstream coding region determinants of bacterio-opsin, muscarinic acetylcholine receptor and adrenergic receptor expression in Halobacterium salinarum.

The aim of this work is to develop a prokaryotic system capable of expressing membrane-bound receptors in quantities suitable for biochemical and biophysical studies. Our strategy exploits the endogenous high-level expression of the membrane protein bacteriorhodopsin (BR) in the Archaeon Halobacterium salinarum. We attempted to express the human muscarinic acetylcholine (M(1)) and adrenergic (a2b) receptors by fusing the coding region of the m1 and a2b genes to nucleotide sequences known to direct bacterio-opsin (bop) gene transcription.
