Paired comparison of bathwater versus oral delivery of 8-methoxypsoralen in psoralen plus ultraviolet: A therapy for chronic palmoplantar psoriasis.

BACKGROUND: Both bath psoralen plus ultraviolet A (PUVA) and oral PUVA with 8-methoxypsoralen (8-MOP) have been successfully used for the treatment of recalcitrant palmoplantar psoriasis. This trial was designed to assess the efficacy and side effects of the different treatment modalities in a randomized half-side comparison. METHODS: Eight patients with moderate-to-severe psoriasis on soles (n = 6) and/or palms (n = 8) were randomly assigned to receive bath PUVA treatment on one side and oral PUVA on the other. Initial treatment dose was 50% of the minimal phototoxic dose evaluated for bath PUVA and oral PUVA. Treatment was given three times a week for 4 weeks. Before treatment and every week a severity index (SI) was assessed by summing the scores of erythema, infiltration, scaling and vesicles evaluated on a scale from 0 to 4. After 4 weeks of treatment the half-side trial was finished and the treatment was continued on both sides with the more effective treatment regimen. RESULTS: Both bath PUVA and oral PUVA achieved a reduction of the mean initial SI from 5.9 (95% confidence intervals (CI) 4.5-8.0) to 3.3 (1.8-6.0) (44% SI reduction, P < 0.005, Student's paired t-test) and 6.0 (5.0-7.8) to 2.9 (1.8-4.0) (52% SI reduction; P < 0.005), respectively. The statistical comparison of the entire 4-week study period revealed a significant better effect in lesions treated with oral PUVA compared with bath PUVA (P = 0.033). However, at 4 weeks, there was no significant difference between the achieved SI reduction of oral PUVA and bath PUVA. Systemic side effects (nausea and/or dizziness) were only observed after oral PUVA. CONCLUSION: This study gives evidence that in the first 4 treatment weeks oral PUVA is slightly more effective than bath PUVA but the former has more systemic side effects.

Onychomycosis in Taiwan.

The pathogens of onychomycosis have implications in choosing therapy. We aimed to survey the pathogens of onychomycosis in Taiwan and further analyse the distribution of pathogens in various conditions. We also compared the distribution of pathogens in Taiwan with those in various countries. This study included 182 cases of onychomycosis who attended our clinic between January and December 2001. Histopathologic examination and fungus culture of the nail specimens were performed to confirm the diagnosis and identify the pathogens. The pathogens were dermatophytes in 101 patients (55.5%), Candida in 66 (36.3%), and non-dermatophyte moulds in 16 (8.2%). Candida was more frequently seen in patients older than 60 years (40.9%), females with fingernail onychomycosis (66.7%) or combined fingernail and toenail onychomycosis (58.3%), and presence of paronychia (57.9%). Dermatophytes are the predominant pathogens in temperate Western countries; meanwhile, Candida and non-dermatophyte moulds are prevailing in Mediterranean and tropical countries including Taiwan. Clinicians should appreciate that the pathogens of onychomycosis may vary in different patient groups and geographical locations, and choose optimal antifungal agents accordingly.

Study of onychomycosis in India.

Fungal agents causing onychomycosis in an Indian population were studied in a hospital based study. It revealed that onychomycosis is more common in adult males, and that finger nails were more often affected compared with toe nails. Occupation did not seem to be related to infection. Trichophyton rubrum was the commonest fungus isolated (49.3%) followed by Candida species (23.2%). Four morphological varieties of Tr. rubrum colonies were observed but the role of a particular variety in causing chronic infection could not be ascertained.

[Human parvovirus B19 infection which first presented with petechial hemorrhage, followed by papular-purpuric gloves and socks syndrome and erythema infectiosum].

A case of human parvovirus B19 (B19) infection is reported. A 6-year-old previously healthy girl was admitted to our hospital complaining of slight fever and petechial hemorrhage on her neck, trunk and the proximal parts of extremities. On admission, the platelet count was within normal range (180 x 10(3)/microliter) but white blood cells and reticulocytes were moderately suppressed (2.4 x 10(3)/microliter and 1@1000, respectively). The purpura disappeared in a week and the blood cell counts fully recovered without any specific treatment. Detection of B19 DNA and anti-B19 IgM antibody in the serum on admission led to the final diagnosis. Since the cellular receptor for B19, the blood group P antigen, is expressed on vascular endothelial cells as well as erythroid progenitor cells, the purpura was considered to be the result of direct vascular injury. She was very unique as she subsequently exhibited papular-purpuric gloves and socks syndrome and erythema infectiosum during follow-up. This case may provide a new insight into the pathogenesis of cutaneous manifestations of B19 infection.

Onychomycosis: pathogenesis, diagnosis, and management.

Although not life-threatening, onychomycosis (a fungal infection of the nail, usually caused by a dermatophyte) constitutes an important public health problem because of its high prevalence (about 10% of the U.S. population) and associated morbidity. The disease can have certain negative consequences for patients, such as pain, and can potentially undermine work and social lives. This review discusses the etiology, classification, diagnosis, and treatment of onychomycosis. Four types of onychomycosis are recognized based on the site and pattern of fungal invasion. Dermatophyte fungi are the predominant pathogens, but yeasts (especially Candida albicans) and nondermatophyte molds may also be implicated. Accurate diagnosis requires direct microscopy and fungal culture. The differential diagnosis includes psoriasis, lichen planus, onychogryphosis, and nail trauma. Onychomycosis is more difficult to treat than most dermatophytoses because of the inherent slow growth of the nail. Older antifungal agents (ketoconazole and griseofulvin) are unsuitable for onychomycosis because of their relatively poor efficacy and potential adverse effects. Three recently developed antimycotic agents (fluconazole, itraconazole, and terbinafine) offer high cure rates and good safety profiles. In addition, the short treatment times (< 3 months) and intermittent dosing schedules are likely to enhance compliance and reduce the costs of therapy.

Palmoplantar pustulosis and sternocostoclavicular arthro-osteitis.

Seventeen patients with shoulder pain and radiographic involvement of the sternoclavicular or sternocostal joints, or both, are described. Eleven of these patients also had palmoplantar pustulosis. Histological examination of the joints showed chronic and subacute inflammation, increased osteoblastic activity, and cartilage degeneration. Propionibacterium acnes was cultured in tissue samples from seven of the 15 biopsied patients, a finding at variance with those of previous reports. The possibility that sternoclavicular arthro-osteitis is of infectious origin should be the subject of further investigation. Non-steroidal anti-inflammatory drugs (NSAIDs) may provide pain relief, possibly owing to their inhibitory action on osteoblasts. In cases of severely restricted movement or severe pain resection of the medial clavicle may be considered.

Palmoplantar pustulosis and smoking.

A multicentre case-control study of 216 patients with palmoplantar pustulosis and 626 controls with miscellaneous dermatoses showed a considerably higher prevalence of smoking in the group with palmoplantar pustulosis. This was the first indication that smoking may be an important factor in this skin disease, possibly by affecting the inflammatory responses of the skin.

Palmar-plantar erythema associated with combination chemotherapy.

We report three cases of a distinctive palmar-plantar erythema associated with the treatment of non-Hodgkin's lymphoma and acute myeloid leukaemia. The rash is characterized by a painful, sharply demarcated, intense erythema of the palms and/or soles followed by bulla formation, desquamation and healing. The eruption is self limiting in nature and did not adversely affect prognosis. Treatment need be neither altered nor stopped; only symptomatic measures are required.
