Psoriatic erythroderma: a histopathologic study of forty-five patients.
There are conflicting opinions about the diagnostic value of skin biopsy in erythrodermic psoriasis. ⋯ When features of early lesions of psoriasis are found during the evaluation of a biopsy specimen from a patient with a clinically nonspecific erythroderma, the dermatopathologist should be aware that this patient could have psoriasis and a renewed anamnesis and a close follow-up should be made.

Comparative StudyAntiseptic effect of povidone-iodine solution on abdominal skin during surgery and on thyroid-gland-related substances.
No definite guidelines have been published concerning the suitable exposure time and frequency of skin antisepsis of the operative field. In the present study, the antiseptic effect of a single use (single-application group) of 10% povidoneiodine solution for skin antisepsis was compared with its triple use (triple-application group). The exposure time was 2 min for both groups. ⋯ Blood levels of total iodine and thyroid-gland-related substances remained within the normal range in all cases. However, in cases receiving a large amount of 10% povidone-iodine solution a transient elevation in blood total iodine was observed. Thus, the 10% povidone-iodine solution is considered to be safe and effective for skin antisepsis of the operative field when applied repeatedly in a small amount per dose with an exposure time of about 2 min.

Investigation on the efficacy of povidone-iodine against antiseptic-resistant species.
The bactericidal activity of commonly used antiseptics against clinical isolates was determined. It is noteworthy that povidone-iodine (PVP-I) solution showed high bactericidal activity against all of the test strains after 30 s of exposure. However, in the case of chlorhexidine gluconate (CHG), residual bacteria were observed in most species. ⋯ No decrease in viable cell count was seen even after a 60-min exposure to any of the other antiseptics. PVP-I showed high activities in all the tests conducted in this study. Thus, PVP-I was confirmed to be a clinically useful antiseptic.

Prevention of catheter-associated urinary tract infection by meatal disinfection.
The incidence of catheter-associated urinary tract infections (UTIs) becomes higher with prolongation of the indwelling period of a catheter. As to the entry of bacteria, ascending UTIs have now attracted attention. In the present study. the metal area was examined bacteriologically and the possibility to use antiseptics for blocking the route of developing infections was investigated. ⋯ It was found that reduction in bacterial count by antisepsis is effective to prevent ascending UTIs. Moreover, once daily application of povidone-iodine was proven to be effective in male patients. The effective antisepsis in females was twice daily application of povidone-iodine.

Demodex folliculorum (DF), which is a resident in human pilosebaceous follicles, has been implicated in infections of patients under cancer chemotherapy and with AIDS. ⋯ Our findings indicate that there may be other factors than immunosuppressive therapy influencing DF density.
