Assessing hair shedding in children.

BACKGROUND: The wash test is currently used to assess hair shedding, though it lacks a cut-off point of normality and any evidence of being reliable. The aim of this study is to provide data to fulfil those needs. METHODS: The wash test was employed in a standardized way on 31 children aged 3-11 years. RESULTS: The test yielded 10.68 +/- 3.91 hairs, a figure which may be considered as 'normal' for children of that age. The chi(2) test granted the validity of the method. The number of shed hairs counted in the washing basin increased with the age of the subjects. COMMENT: The wash test proved to be reliable and to be a useful tool for monitoring hair shedding. The increasing trend with age may suggest a possible prepubertal onset of androgenetic alopecia.

Counterimmunoelectrophoresis, ELISA and immunoblotting detection of anti-Ro/SSA antibodies in subacute cutaneous lupus erythematosus. A comparative study.

Patients with subacute cutaneous lupus erythematosus (SCLE) have circulating antibodies to Ro/SSA directed to two antigenically distinct ribonucleoproteins of 60 kDa and 52 kDa. Three laboratory tests may be used to detect anti-Ro/SSA antibodies: counterimmunoelectrophoresis (CIE), enzyme-linked immunosorbent assay (ELISA) and immunoblotting (IB). Their relative efficacy and clinical correlations were ascertained. We determined anti-Ro/SSA antibodies with CIE, with two different ELISA methods (ELISA 1 and 2) and with IB in 29 SCLE patients. Anti-52 kDa and -60 kDa Ro/SSA antibodies were also assayed with IB. In addition, we determined antinuclear antibodies with indirect immunofluorescence, anti-Sm, anti-RNP, anti-La/SSB and anti-Ro/SSA antibodies with CIE and ELISA, and anti-nDNA and cardiolipin antibodies using an ELISA method. CIE detected anti-Ro/SSA antibodies in 22 patients while ELISA 1 and 2 did so in 17 and 18 patients, respectively. In five patients, IB revealed a reactivity to 60 kDa polypeptides and in two, a reactivity to 52 kDa polypeptides. Of these seven patients, four had a myocardial infarction. Of these, two reacted to the 52 kDa antigen and two to the 60 kDa antigen. A combination of techniques was often needed to detect all specificities. ELISA proved to be very specific and sensitive. The IB technique detected a group of patients with myocardial infarction. A case-control study is needed to confirm the data of cardiac involvement.

Cutaneous mucinoses and HIV infection.

In the last few years cutaneous mucinoses have been reported with increased frequency in HIV patients. We report the occurrence of scleredema, reticular erythematous mucinosis and lichen myxoedematosus in three different HIV-infected patients, review the literature and discuss the possible relationship between mucin deposits and HIV infection. This is the first report of scleredema and the second of reticular erythematous mucinosis in an HIV-infected patient. Only the association of HIV infection with lichen myxoedematosus seems to be more than coincidental.
