Ungual warts: comparison of treatment with intralesional bleomycin and electroporation in terms of efficacy and safety.

BACKGROUND: Ungual warts are considered the most common benign nail tumour, and they are caused by the human papillomavirus. Despite the numerous treatments reported in the medical literature, ungual warts are considered frustrating, with high relapse rates and a potential risk of nail dystrophy. Bleomycin is a therapeutic option showing a good safety profile and high cure rates. OBJECTIVE: To evaluate the efficacy of electrochemotherapy using intralesional bleomycin for the treatment of ungual warts in comparison with intralesional bleomycin alone and describe the side-effects related to the use of both techniques. METHODS: This was a prospective, randomized, double-blind, controlled clinical trial. Forty-four 18- to 60-year-old female and male patients with ungual warts of only one finger were included. The patients were divided into two treatment groups: GA - intralesional bleomycin; and GB - electroporation and intralesional bleomycin. Following a single application, the patients were followed up for 180 days. RESULTS: The patients' mean age was 36 years for GA and 37 years for GB. Most patients were female (68%). Of 22 patients in GA completing the study, 11 (50%) achieved the cure, while 18 (85.7%) of 21 patients completing the study in GB showed cure. A significant association of patients with or without cure after the GA and GB treatments (P = 0.022) was observed. None of the patients in either group had systemic side-effects. Independent of the technique used, all the participants considered the adverse effects tolerable. CONCLUSION: The intralesional use of bleomycin associated with electroporation for the treatment of ungual warts (both periungual and subungual) showed a statistically superior cure when compared with intralesional bleomycin alone. Side-effects were more frequently observed in the electrochemotherapy with bleomycin group than in the bleomycin monotherapy group.

Skin cancer prevention campaign in childhood: survey based on 3676 children in Brazil.

BACKGROUND AND OBJECTIVES: Primary skin cancer prevention campaigns are essential and more effective among children, not only because of the importance of sun exposure effects during this period, but also because this age is when individuals are developing behaviours. The Brazilian Society of Dermatology - Regional State of Sao Paulo developed and conducted the programme named 'The Sun, Friend of Childhood', a school health education and disease prevention project for children and parents. Our objective was to evaluate the cognitive and behavioural effects of the children and parents before and after an education model-based intervention of sun protection. METHODS: We carried out a study on a school population of Social Service of Industry - Regional State of São Paulo, from the first to the fifth years of the regular course (6-10 years). Our educational project was planned to be based on two children's learning tools (comic magazine and a DVD cartoon). Questionnaires in relation to habits and knowledge in sun exposure were applied to the children (3776) before and (2748) after the intervention. A questionnaire was applied to 3663 parents regarding personal details and habits of their children. RESULTS: According to the McNemar's statistical test, all changes in the children in acquiring new knowledge about good practices for sun exposure were statistically significant. CONCLUSIONS: Educative sun exposure programmes in childhood are a relevant tool to modify the history of life for next generations, to concern the skin cancer and good health practices.

Thiamphenicol in the treatment of chancroid. A study of 1,128 cases.

Thiamphenicol, an aminic derivate of hydrocarbilsulfonil propandiol, was used for the treatment of 1,171 chancroid bearing patients. Each patient was medicated with 5.0 g of granulated thiamphenicol, orally, in a single dose, and was reevaluated 3, 7 and 10 days after the treatment. Ten patients (0.89%) did not respond to the proposed treatment. 133 patients presented healed ulcers after 3 days of treatment, 976 patients healed chancres on the seventh day after the treatment, and 39 patients took 10 days to present healed chancres. The results of this study indicate that the rate of patients that were cured, the low incidence of side effects, and the practicality of administration make of thiamphenicol an excellent choice for the treatment of chancroid.

Mycetoma: a retrospective study of 41 cases seen in São Paulo, Brazil, from 1978 to 1989.

Clinical and epidemiological aspects of 41 cases of mycetoma seen in São Paulo city from January 1978 to December 1989 are presented. Twenty-eight cases (68%) were caused by actinomycetes, while 13 (32%) were caused by true fungi. In only 22 (78%) actinomycetoma cases was it possible to identify the agent. Nocardia brasiliensis, by far the commonest actinomycete isolated, was responsible for 13 cases. Among eumycetomata, Madurella grisea was isolated from 3 cases, Scedosporium apiospermum from 2 cases, and Madurella mycetomatis from 1 case, and in 7 cases the agent was not identified. Distribution by sex and age was similar to that reported in the literature. Feet and legs were the commonest sites affected. The mean age of actinomycetoma patients was 33.2 years, while patients with eumycetomata were an average of 32.8 years. Mean duration of the disease was 6.8 and 9.8 years respectively. Most patients came from rural areas in the north-eastern region of the country and worked as field labourers. Bone involvement was frequent for both actinomycetomata and eumycetomata and was characterized by osteoporosis, periostal reaction and cavitation. The authors' elected treatment consists of combining sulfamethoxazole (800 mg) and trimethoprim (100 mg) with prednisone (10 mg) orally, daily.

Successful treatment of sporotrichosis with oral fluconazole: a report of three cases.

We report three cases of sporotrichosis successfully treated with oral fluconazole. A verrucous lesion on the toe was cured after 126 days, and a lesion on the left foot resolved after 91 days' treatment. A case of lymphangitic-type sporotrichosis required 174 days of treatment to achieve a cure, and a higher dose (400 mg daily) was necessary in this case. Any side-effects were insignificant. We conclude that this new bis-triazole compound can be successfully used as an alternative treatment for sporotrichosis when conventional drugs must be avoided.

[Black-grain eumycetoma due to Madurella grisea. A report of 2 cases]. / Eumicetoma de grãos pretos por Madurella grisea. Registro de dois casos.

Two cases of black grains eumycotic mycetoma, occurring on a foot, are reported. Both proceeded from the state of Bahia (Brazil), and in both the etiologic agent was Madurella grisea Mackinnon et al., 1949. The grains structure as well as the micromorphologic characteristics of the fungus in saprophytic life were studied. It is the author's belief that these observations correspond to the 7th and 8th cases reported in the Brazilian medical literature. The authors do consider the following Madurella species as nomen dubium or nomina confusa: M. ramiroi, M. oswaldoi, M. bovoi, M. tozeuri, M. mansonii, M. brumpti, M. reynieri, M. americana, M. lackawanna e M. ikedae and the same for Rubromadurella mycetomi. The only valid species must be Madurella mycetomatis McGinnis, 1980 (= Madurella mycetomi Brumpt, 1905) and Madurella grisea Mackinnon et al., 1949. Treatment with itraconazole in both reported cases, for a 3 month duration, did not produce any regression of the lesions, the clinical improvement being meager.

The authors report one case of leishmaniasis in a 60 year old patient who developed renal failure after treatment with Glucantime. With the interruption of these drug the patient recovered her normal renal function, and a new treatment with Amphotericin B was tried with complete cicatrization of the lesions.

[Itraconazole in the treatment of pityriasis versicolor: comparison between 5 and 7 days of treatment]. / Itraconazol no tratamento da pitiríase versicolor: comparação entre 5 e 7 dias de tratamento.

The authors present the results obtained in the treatment of pityriasis versicolor with Itraconazole, comparing two schemes of treatment, in an open trial: 200 mg daily, for 5 and 7 days. The clinical diagnosis was confirmed by Wood's light and mycologically, by direct examination. The patients were controlled 21 and 35 days after beginning the treatment. The evaluation of the results showed that both schemes were effective. At the second control, there was clinical and mycologic cure in 90% of the patients from the 5-day group and in 95% of the patients from the 7-day group. The tolerance was good: 2 patients from the 7-day group and 1 patient from the 5-day group showed side-effects. Since there was no significant difference between the two schemes of treatment, the authors recommend the shortest one, that is, 200 mg daily for 5 days.
