    Notes: We present a new case of irreversible hair matting, a rare, but important and alarming, acquired hair disorder. This case was investigated to test the causal hypothesis proposed in 1984. At the same time four other specimens of matted hair from patients and tangles from normal individuals were also examined. Light and electron microscopy showed dramatic permanent twisting and bending of the hairs through 180°. There was marked variation in the fibre width of hairs from matted samples, with some longitudinally split along a considerable length. This bending and entanglement of hairs of varying widths (felting) seemed to be the main reason for the hairs becoming so dramatically knotted together in four of the cases. In only one case was there any evidence of a viscous fluid binding the hair together. This finding suggests that there may be two different mechanisms involved in hair matting.

    An epidemiological profile of in-patient workload in dermatology (1992)

    Notes: Trends in admission rates, patterns of readmission, lengths of stay and clinical caseload for in-patient dermatology from 1976 to 1985 are described using data from the Oxford record-linkage study. Age-specific admission rates were considerably higher in people aged 50 years and over than in younger people. Admission rates declined over time in most age-sex groups below the age of 70 years, but increased over time for the over 70s. In dermatology, unlike most other specialties, the length of patients' stay did not decrease substantially over the 10 years. In-patient workload consisted predominantly of leg ulcers, psoriasis, and eczema. This did not change appreciably over time. New out-patients at dermatology clinics rose by 41% from 1976 to 1985, and all out-patient visits rose by 20% during the 10-year period. Because the profile of in-patient workload changed relatively little over time, we speculate that the impact of innovations in dermatological practice has been much greater in the ambulatory setting than in the management of those patients requiring prolonged in-patient care. Future routine measures of workload in dermatology should include demographic and clinical data on out-patients.

    Notes: Though circumcision has long been known to cure Zoon's balanitis, this mode of treatment has been largely neglected by many leading authorities in recent times.In this report we describe two patients who failed to respond to recommended topical treatment but who were rapidly cured by circumcision.

    Cheveux incoiffables—diagnostic, clinical and hair microscopic findings, and pathogenic studies (1994)
    Oxford, UK : Blackwell Publishing Ltd
    British journal of dermatology 131 (1994), S. 0 
    Details

    Notes: Three possible mechanisms of the hair shaft abnormality in cheveux incoiffables have been investigated in nine patients. Cheveux incoiffables hairs were found to exhibit a normal distribution of cystine-rich protein within both the cuticle and the cortex, as determined by silver methenamine ultrastructural cytochemistry. Resistance to stretching, at 65% relative humidity and constant temperature, was similar to normal controls. Resistance to bending forces was also assessed, and was equivalent in both groups. On scanning electron microscopy, all patients with cheveux incoiffables demonstrated longitudinal grooving of the hair shaft, and the hairs were triangular or heart-shaped in cross-section. In addition, there appeared to be minimal cuticular weathering. Even hairs of 20–30 cm length showed only minimal cuticular and cortical weathering, compared with normal hair shafts of similar length and diameter. It is possible that the reduced progressive weathering renders the hair shaft more rigid, and could serve to explain the ‘stand on end’ appearance of the hair which is typical of this condition. However, the characteristic cross-sectional shape of the hair shaft in cheveux incoiffables may render it more rigid and resistant to bending forces. This latter theory has yet to be fully investigated.

    Trichothiodystrophy: an electron-histochemical study of the hair shaft (1984)

    British journal of dermatology 110 (1984), S. 0 
    Details
    ISSN: 1365-2133
    Source: Blackwell Publishing Journal Backfiles 1879-2005
    Topics: Medicine
    Notes: We have used sensitive electron-histochemical methods to study the subtle ultrastructural variations of cystine incorporation into the hair shaft in trichothiodystrophy.We have shown a general reduction in the cystine (sulphur) content of both the cuticle and the cortex Discontinuity, and in some cases, complete absence of the cuticular A-layer results in premature weathering of the cuticle and weakening of the hair shaft. The ultrastructural findings support the work of Gillespie & Marshall (1981) in demonstrating the absence or re-characterization of the high sulphur matrix proteins and show further evidence for the incorporation, and abnormal distribution and deposition of sulphur-rich proteins in hair cortex and cuticle.We conclude that the similar yet different results obtained from each patient's hair sample are characteristic of trichothiodystrophy, a neuro-ectodermal symptom complex which may represent a final common pathway of more than one metabolic disturbance.

    Treatment of erythroplasia of Queyrat with liquid nitrogen cryosurgery (1982)

    Notes: Erythroplasia of Queyrat is now generally considered to be Bowen's disease of the glans penis. The literature is reviewed and the need for a treatment that is destructive to abnormal tissue yet cosmetically acceptable is stressed.Cryosurgery appears to be a very appropriate form of treatment for this condition – its effectiveness was demonstrated in two cases.

    Pili annulati: electron histochemical studies on affected hairs (1981)
    Oxford, UK : Blackwell Publishing Ltd
    British journal of dermatology 105 (1981), S. 0 
    Details
    ISSN: 1365-2133
    Source: Blackwell Publishing Journal Backfiles 1879-2005
    Topics: Medicine
    Notes: In this study we have shown that in pili annulati all the normal layers within each cuticle cell are present, and show a normal distribution of cystine. The presence of well ordered macrofibrils, composed of microfibrils embedded in a cystine rich matrix, in both regions of the hair shaft indicates that normal keratinization can and does take place. We have demonstrated the presence of electronopaque, cystine positive material at the intermacrofibrillar spaces and suggest that the presence of the cortical holes is in part due to insufficient cortical material to occupy the space available, and in part due to the dissolution of the intermacrofibrillar material, possibly by water or other chemical agents, diffusing through an apparently more permeable cuticle.

    Pityriasis rubra pilaris: epidermal cell kinetics (1981)

    Notes: Epidermal proliferative kinetics were studied in a patient with pityriasis rubra pilaris. Elevated proliferative indices (flash labelling and mitotic indices) were apparent compared with normal epidermis and measurements of the birth rate indicate that the rate of epidermal cell production was similar to that found in psoriasis, and equalled 11.8 cells/1000 germinative cells/h; this suggests a cell cycle time of 60 h.Contemporaneous measurements of the rate of entry into DNA synthesis showed values similar to the rate of entry into mitosis; hence there is no G2 cell loss as appears to occur in the hyperproliferative psoriatic epidermis.
