Poroqueratosis (PQ) refers to a group of disorders of keratinization with the common histological feature of the presence of cornoid lamellae, narrow columns of parakeratosis on a focally disorganized epidermis.1 We present 2 patients with lesions compatible with linear PQ, with extensive involvement of one side of the body. The first patient was a 23-year-old man with no past history of intere...

A 60-year-old woman with plaque-type psoriasis of 30 years' duration was treated with etretinate. The lesion resolved while the patient was on the drug and continued to resolve after she had discontinued therapy. The continuation of resolution after the patient had discontinued the drug is probably due to its long half-life.

The commercial BD ProbeTec ET (BDPT) system for the detection of Neisseria gonorrhoeae and Chlamydia trachomatis from clinical specimens was compared with our in-house LightCycler real-time PCR (LC-PCR) assays. Specimens initially positive by the BDPT system were retested by our LC-PCR assays. Our results for C. trachomatis testing indicate a 91.2% agreement when the results of 114 clinical spe...

Semiconductor nanoparticles (NPs) are being actively explored for applications in medical diagnostics and therapy and numerous electronic devices including solar cells. In this paper we demonstrate the influence of the third generation rigid polyphenylenepyridyl dendrimers (PPPDs) of a different architecture on the formation of well-defined CdS NPs. A high temperature approach to the synthesis ...

The three-dimensional findings of the surface and from a cross section from a case of disseminated superficial porokeratois using scanning electron microscopy are reported. On the surface of the skin, irregular keratin with a serpiginous distribution was seen. A gross aspect of keratin in the hyperkeratotic wall was also observed and compared to the normal area, in which the release of corneocy...
