Keratosis follicularis spinulosa decalvans: report of a case with ultrastructural study and unsuccessful trial of retinoids.

Keratosis follicularis spinulosa decalvans (KFSD) is a genetic disorder characterized by disseminated follicular hyperkeratosis, especially localizated to scalp and face. We report the case of a new patient displaying typical features of KFSD. Ultrastructural study was performed and displayed round keratohyalin granules in follicular keratinocytes. Trial with etretinate, which has not been reported before in this disease, proved to be ineffective.

Primary localized cutaneous nodular amyloidosis: case report and biochemical analysis of amyloid.

We report a patient with scalp lesions of primary localized cutaneous nodular amyloidosis. The extensive examination revealed no systemic involvement. Analysis of glycosaminoglycans (GAGs) in amyloid deposits showed a twofold increase as compared with normal skin, which was due to the increase in dermatan sulfate. Local disorders of GAG metabolism may be related to the amyloid fibril formation. Amyloid fibrils were purified and identified electron-microscopically, which consisted of two major 12,000- and 13,000-dalton and minor 29,000- and 48,000-dalton peptides. Western blotting analysis showed a minor 29,000-dalton peptide reactive with antibodies against both kappa and lambda light chains of immunoglobulin. There is a possibility that some components of amyloid in some cases of primary localized cutaneous nodular amyloidosis may consist of both kappa and lambda immunoglobulin light chains.

Dissecting cellulitis of the scalp in 2 girls.

Two girls with dissecting cellulitis of the scalp are described. In one Pseudomonas aeruginosa was isolated from the sinus discharge. Both patients were controlled with prolonged antibiotic therapy and periodic aspiration of the fluctuant lesions. Role of infection in perpetuating the condition is highlighted.

Additional effect of grenz rays on psoriasis lesions of the scalp treated with topical corticosteroids.

In a double-blind study comprising 17 patients with symmetrical psoriasis lesions of the scalp, the combination of grenz ray treatment and topical steroid showed a faster clearing than with the topical steroid alone. The results also indicate a longer remission time with the combination therapy compared to grenz rays alone. Therefore both the faster clearing and the longer remission time with the combination therapy, as compared to our previous study of grenz ray treatment of scalp psoriasis, are probably due to the additional effect of steroid therapy, on grenz rays.

Acute ocular hypotony. A rare complication of temporal arteritis.

Acute ocular hypotony is a serious, but rare complication of temporal arteritis. It occurs equally often in men and women, and appears mostly in patients older than 70 years. This complication may occur in one or in both eyes. In the literature 7 cases of temporal arteritis accompanied by ocular hypotony have been reported. Hypotony probably results from a restricted production of aqueous humor caused by involvement of the arteries supplying the ciliary body. A high-dose corticoid therapy may normalize completely the intraocular pressure, and a timely treatment may preserve a satisfactory vision, since an insufficient perfusion of the optic disc does not necessarily occur. Scalp necrosis and diplopia may appear at the same time, and are a sign of multiple involvement of the arterial vessels.

Cytodiagnosis of simple and proliferating trichilemmal cysts.

OBJECTIVE: To elucidate the cytologic findings in simple trichilemmal (pilar) cysts and proliferating trichilemmal cysts (pilar tumors) and the clinical importance of these lesions. STUDY DESIGN: Aspirates from 12 simple pilar cysts and three pilar tumors, all histologically confirmed, were analyzed with a view to elaborating on specific cytologic features enabling a distinction from epidermal cysts and other adnexal tumors. RESULTS: Aspirates from pilar cysts showed two different pictures, depending on the age of the cyst. Young pilar cysts showed aspirates with an abundant background of blotchy keratin with or without calcification and inflammation. Older (degenerating) cysts showed oily fluid debris with cholesterol crystals and inflammatory cells. The epithelial component was sparse, and only an occasional syncitial cluster of small squamoid cells was seen. As opposed to this, epidermal cysts usually showed a cleaner background, with very cellular aspirates containing many nucleate and anucleate squames, keratin flakes, platelike crystals and no calcification. The pilar tumors showed a lesser amount of keratin as compared to pilar cysts and yielded large and small clusters of squamoid and basaloid cells, a few of which showed an abrupt association with anucleate, keratinized globules. CONCLUSION: The cytologic diagnosis of a pilar cyst should be made especially in scalp cysts, which yield either abundant, blotchy keratin or oily, cholesterol-rich debris with a sparse epithelial component and which lack a mixture of anucleate and nucleate squames. On aspiration, pilar tumors yield comparatively more cells and less keratin and show small, basaloid or squamoid cells abruptly associated with keratin globules. The cytologic diagnosis of pilar cysts is important because these cysts recur if incompletely excised and often undergo transformation to pilar tumors. Similarly, pilar tumors often clinically mimic squamous carcinomas, and hence there is a need to outline definitive cytologic features.

Economic considerations associated with Pediculus humanus capitis infestation.

An estimated 6 to 12 million head lice infestations occur in the United States annually, with children ages 3 to 12 most likely to be affected. There are significant direct costs associated with treatment and indirect costs due to lost time from school. Anecdotal reports suggest that direct costs of treatment are in the hundreds of millions of dollars annually. Indirect costs are also substantial but more difficult to quantify. Examples of indirect costs include missed days from schools that use a "no nit" policy, lost wages for parents who must stay home with children, and costs of daycare for parents who cannot miss work. Contributors to the expense of treating head lice include misdiagnosis, and, consequently unneeded treatment; treatment failure due to misuse of pediculicides or other agents; and developing resistance, particularly to over-the-counter pyrethroid agents. An overview of direct and indirect costs of infestation are included in this review, along with a discussion of factors that lead to misuse and overuse of pediculicides. More accurate diagnosis of head lice infestation may provide the most effective means of controlling the costs of care and ensuring proper use of pediculicides.

Scaling scalp diseases in children.

Scaling scalp diseases in 142 children were evaluated. Included were seborrheic dermatitis, atopic dermatitis, tinea capitis, and psoriasis. Clinical signs were noted, and various treatments were then undertaken. Patients with seborrheic dermatitis responded well to treatment with antiseborrheic shampoo and topical corticosteroids. Atopic disease was more resistant to treatment, but did improve with less frequent shampooing and twice daily topical corticosteroid application. Selenium shampoo was a useful adjunct in the treatment of tinea capitis (cultures became negative at two weeks compared to persistent positivity in other treatment groups).

Wet combing for head lice: feasibility in mass screening, treatment preference and outcome.

There is no scientific consensus on the best way to control head louse infestation in schoolchildren. A study was conducted to test the feasibility and acceptability of a screening campaign by wet combing and a community approach to head-louse control with home visits, and to explore parents' treatment preferences and treatment outcomes. A non-controlled intervention (advice on treatment options offered to all positive children) was nested within an epidemiological prevalence study. All children in three primary schools in Ghent, Belgium, were invited to take part in screening by wet combing (n=677, 3-11 years). Positive children were offered structural treatment advice, a home visit on day 7, and a check by wet combing on day 14. 83% of the children were screened. The prevalence of active infestation (living moving lice) was 13.0% in school 1 and 19.5% in school 3. In school 2, prevalence of signs of active and past infestation was 40.7%. A home visit was made to 58% of the positive children. 85% of the positive children were screened again on day 14. Wet combing was the most widely used treatment, followed by chemical treatment and a combination of the two. In school 1 and 3 51% were cured, and in school 2 24% became nit-free. A wet combing screening campaign and a community-oriented approach to head-louse control is feasible though resource-intensive. The prevalence of head lice was high and the cure rate was low, with either topical treatments or wet combing.
