Method to measure force required to remove Pediculus humanus capitis (Phthiraptera: Pediculidae) eggs from human hair.

Head lice are very common and mainly affect children between 3 and 12 yr old. Little is known about the way nits, the eggs of the head louse, are attached to the hair. In this report, an objective measurement procedure for the ease with which nits can be removed is presented. The first peak force, associated with the start of nit movement, and the average and maximal force during the sliding of the nit were measured. The three force variables correlated with the length of the cylinder by which the nit was attached to the hair. A negative correlation was found between the maximum force exerted and the distance of the nit from the scalp. The method described in this report can be used to determine the in vitro efficacy of various products to remove nits.

Inter-observer variation in the histopathological diagnosis of clinically suspicious pigmented skin lesions.

When a biopsy is taken of a suspicious pigmented skin lesion, histological examination is expected to establish the definitive diagnosis. This study evaluated the inter-observer variation of 20 pathologists in the histological diagnosis of a randomly selected set of suspicious pigmented skin lesions (PSLs), by comparing their diagnoses to a reference diagnosis. Overall sensitivity for melanoma was 87%, ranging from 55% to 100% between the observers. Sensitivity was significantly lower for thin (Breslow thickness <1 mm) than for thick melanomas (83% versus 97%, p=0.005). Overall melanoma specificity was 94%, ranging from 83% to 100% between observers. Dysplastic naevus was the most important source of false-positive diagnoses, mainly in situ melanomas. Positive and negative predictive values in the given test set were 75% and 97%, respectively. In the case of melanoma, there was quite some variation in measured Breslow thickness. This would have led to a different therapeutic approach in 12% of the readings. Some of the variation seemed to be due to a different interpretation of the presence of a co-existent naevus. In 9% (3/35) of the readings, participants did not agree on the presence of ulceration. These results reflect a tendency to overdiagnose mainly thin melanomas in general histopathological practice. They also demonstrate variation in the assessment of major prognostic factors of melanoma.

Knowledge and management of scabies in general practitioners and dermatologists.

Scabies is an infectious skin disease with an increasing incidence during the past decade. A survey was conducted among general practitioners (GPs) and dermatologists in the region of Ghent, Belgium, to explore their knowledge on scabies. Information on the treatment advice given and the frequency of reporting scabies to the Health Inspection was also collected. The scores on the knowledge test were of an acceptable level in both GPs and dermatologists (median score 59% and 79% respectively). We found that profession (dermatologist versus GP), the number of years of experience and the estimated number of scabies patients per year had a significant effect on this score. Permethrin cream, currently regarded as the standard treatment, is prescribed as the only treatment for scabies by half of the GPs and dermatologists. Almost 50% of the GPs and dermatologists indicated they rarely or never report scabies to the Health Inspection. As a result the correct incidence of scabies in Belgium, as in many other countries, is not known.
