    Notes: Summary The aim of this study was to compare the efficacy and tolerability of twice-daily vs. once-daily regimes of dithranol (anthralin) in Lassar's paste. Over a 4-year period, 61 inpatients with stable plaque psoriasis gave informed consent and entered a randomized controlled trial, having twice or once-daily application of dithranol in Lassar's paste as part of otherwise standard Ingram's regime. Primary outcome measurements were time required in hospital, nursing time, changes in total body surface area affected by psoriasis and thickness of a target plaque and in some patients, an assessment of the recurrence of psoriasis. Doctors were blinded as to the regime being used. At entry, mean patient age, lesional surface area and target plaque thickness were comparable in both groups and no patient had received systemic therapy in the preceding 3 months. Forty-two patients completed the study, two (11%) in the twice-daily group withdrawing due to skin irritation or ‘burning’. Mean lesional surface area and target plaque thickness were similar in both groups at hospital discharge. Mean (± SD) time spent in hospital was not significantly different in each group, being 13.3 (± 6.2) days and 13.9 (± 4.5) days for the twice-daily and once-daily groups, respectively (P = 0.36). Duration of hospitalization did not correlate with surface area or plaque thickness on admission. Mean (± SD) nursing time spent on treatment was significantly greater in the twice-daily group, at 0.82 (± 0.33) hours per day compared with 0.51(± 0.25) hours per day in the once-daily group. Relapse rate at 6 months was not different between the two groups.

    Disappearance of pili annulati following an episode of alopecia areata (2002)

    Notes: Summary Pili annulati is a distinctive autosomal dominant hair shaft disorder that produces alternating light and dark bands that can give a spangled appearance to the hair. The literature contains three case reports of patients in whom the condition has disappeared following recovery from alopecia totalis. None of these reports contain a direct microscopic comparison of pre- and post-regrowth hairs. We report a 6-year-old girl who was first noted to have pili annulati at the age of 2 years and who developed alopecia totalis at the age of 3 years. When the hair regrew spontaneously, 18 months later, the pili annulati was no longer visible. Hair samples obtained before and after the episode of alopecia areata were compared by normal and cross-polarized light microscopy. While not apparent on careful clinical examination, banding was present on light microscopy in 20% of the hairs. Eighty per cent of the affected hairs displayed banding throughout their entire length. In contrast, prior to the episode of alopecia totalis, when the pili annulati was clearly visible, 50% of the hair obtained was banded on microscopy and 90% of the affected hairs showed banding throughout their microscopic length.

    Cytokeratin expression in pili annulati hair follicles (2005)

    Notes: Pili annulati is a rare autosomal inherited hair shaft abnormality of unknown pathogenesis in which clinical examination reveals alternating light and dark bands leading to a shiny appearance of the hair due to cavities within the cortex of the hair shaft. This is the first investigation of the proposed cytokeratin defect in pili annulati hair follicles. Four cryopreserved pili annulati and four control scalp specimens were analysed using immunohistochemistry for different ‘hard’ trichocytic and ‘soft’ epithelial cytokeratins including K1, K6, K10, K14, K16, K17, K18, K19, Ha1 and Hb1. There was no difference in staining intensity and quality of staining pattern seen in pili annulati and control scalp specimens. These results suggest that pili annulati is not caused by a defect of the cytokeratins investigated in this study.

    Keratin expression in the normal nail unit: markers of regional differentiation (2000)
    Oxford, UK : Blackwell Science Ltd

    Notes: Differentiation within the nail unit was examined using a range of antikeratin monoclonal antibodies including the recently described antibody LHTric-1, specific to the acidic hair-type keratin Ha1. Keratinocytes of the nail matrix, nail bed and the digit pulp were characterized by different patterns of keratin expression. Nail matrix was the sole site of expression of Ha1, which colocalized in suprabasal matrix epidermis with epidermal keratins K1 and K10. Small amounts of K17 were found at the apex of the matrix in some cases. K6 and K16 were found where the epidermal surface folds forwards to become the ventral aspect of the proximal nail fold. The nail bed was distinguished by the absence of hair-type keratin Ha1 and the absence of markers of cornified epidermis and mucosal differentiation K1/K10 and K4/K13, respectively, while K6, K16 and K17 were detected. The basal keratin conformation marker, LH6, was expressed suprabasally throughout the nail bed. This complement of keratins exists in the nail bed in the absence of notable proliferative activity, and suggests a state of minimally developed differentiation which may be afforded by the physical or biological properties of the overlying nail. Keratins, K6, K16 and K17 were all found in the digit pulp in limited amounts, possibly in association with the epidermal component of the eccrine duct. The simple epithelial keratins, K7, K8 and K18, were found in small amounts in the specimens from younger individuals, mainly in epibasal cells of the apex of the matrix and in putative Merkel cells.

    Treatment of subungual exostoses by elective day case surgery (1999)

    Notes: Twenty-one patients (11 female, 10 male: mean age 21.3 years) with subungual exostoses were treated with elective surgery under local anaesthetic in a dermatology day case theatre over a period of 8 years. Fifteen (71%) tumours affected the great toe, four (19%) affected other toes and two (10%) affected fingers. All received local excision with great care to remove all tumour residue from the terminal phalanx. Wounds were allowed to heal by secondary intention. Attention was paid to preoperative antiseptic procedure and postoperative analgesia. During follow-up of between 6 and 36 months (mean 17 months), there were two relapses (10%) in the first 12 months, seen in two of the younger subjects aged 9 and 13 years. One required further surgery. One further case suffered long-term dystrophy due to perioperative damage to nail matrix. Conservative and thorough treatment of this pathology can be achieved using the appropriate tools in a dermatology day case theatre.

    Management of nail psoriasis (2000)

    Notes: Nail psoriasis is often difficult to cure, but may respond to a range of different approaches used alone or together. As with treatment of psoriasis affecting skin, relapse is common and therapies may need to be maintained or repeated. The exact benefits of many of these treatments are not well documented in the literature. Basic nail care is important and topical therapies represent the main modality of treatment for the majority of cases. In severe nail disease, where there is a hypertrophic element, injection therapy with triamcinolone may be helpful. PUVA and other forms of radiation may be of benefit, but as with systemic therapy, they are usually useful in the context of treatment of psoriasis elsewhere on the body.

    Clinical relevance of hair microscopy in alopecia (2002)

    Notes: Summary Hair microscopy can clarify the cause of hair loss in a range of diagnoses. Most of these are associated with hair breakage, the rest are related to lack of growth. Hair breakage may be due to excessive trauma or underlying susceptibility, where structural clues may be present. Lack of growth reflects follicular dynamics and represents the central mechanism of most common causes of alopecia. In such conditions, microscopy only reveals nonspecific confirmation of short anagen. Although this may assist clinical diagnosis, microscopy in alopecia only allows exclusion of diagnoses related to hair breakage. Confidence in the outcome of hair microscopy is based on the size of the sample of hairs, the length of the hair, the characteristics of the observations and the experience of the person undertaking the microscopy.
