Liporeduction by endocoagulation.

BACKGROUND: Plastic surgery and dermatologic techniques are constantly being improved, but clinical expression of the aging process and its surgical management remains a challenge. OBJECTIVE: To evaluate an alternative surgical approach for submandibular, mental, and periorbital loose tissue treatment. METHODS: We present a modified transcutaneous bipolar diathermy microprobe using the coaxial principle for the treatment of mental, submandibular, and periorbital loose tissue. RESULTS: The outcome was evaluated as satisfactory for the following reasons: lower morbidity, it is a simple time-saving surgical technique, no healing difficulties, less dehiscence, no wound exposure, minimal incisions, and a faster postoperative recovery with a simple wound care. CONCLUSION: We suggest that this procedure is a simple surgical approach that delays extensive plastic surgery.

Tretinoin peeling.

BACKGROUND: Topical tretinoin has been used for a long time to improve photoaged skin, but this therapy takes quite a few months to show some clinical changes. Because of that, we think tretinoin peeling would be an excellent choice for improvement of photoaged skin. OBJECTIVE: [corrected] Our objective was to show the clinical and histologic modifications of the skin after five sessions of tretinoin peeling. METHODS: The authors studied the clinical and histologic modification that occurred in 15 female patients after conducting tretinoin peeling procedures twice a week in concentrations of 1-5%. Conventional sectioning of punch biopsy specimens was conducted before and after the treatment. RESULTS: Clinical improvement was observed in the skin texture and appearance. Through histologic examinations, a decrease in the corneous layer and an increase in the epidermal thickness were noticed, inducing an improvement of its stratification, as well as the formation of cristae cutis. CONCLUSION: It was concluded that the peeling conducted with serial tretinoin showed good clinical and histologic results, especially for the treatment of photoaged skins I and II, melasma, ephelis, and acne degree I, as well as being practical, quick, and easily accomplished with no side effects.

Efficacy, safety and tolerability of terbinafine for Tinea capitis in children: Brazilian multicentric study with daily oral tablets for 1,2 and 4 weeks.

BACKGROUND: Tinea capitis is a common skin disease seen predominantly in children. The standard therapies for this disease are griseofulvin and ketoconazole. Nevertheless, these drugs have drawbacks in that they are only fungistatic and require treatment for at least 6 weeks. Previous studies with oral terbinafine for the treatment of Tinea capitis have shown that this agent is effective when given for 4 weeks, comparable to an 8-week regimen with griseofulvin. To date there is no data on the use of oral terbinafine in Brazilian children. OBJECTIVES: To assess the efficacy, safety and tolerability of oral terbinafine in short-term treatments (1-, 2- and 4-week treatment) of Tinea capitis in children. PATIENTS AND METHODS: One hundred and thirty-two children aged 1-14 years were enrolled in this study, but only 107 were considered for the final efficacy analysis. Diagnosis included clinical assessment and examination by Wood's light. Confirmation was obtained by direct microscopy and culture for fungus. Terbinafine dosage (125 or 250 mg/day) was adjusted according to patient weight. Efficacy was evaluated both by clinical and mycological assessment. Safety and tolerability variables included data on adverse reaction and clinical laboratory evaluations. RESULTS: Mycological evaluation in the follow-up visit at week 12 showed negative direct microscopy and culture results in 48.6, 60.5 and 69.7% patients in groups 1-, 2- and 4-week, respectively (n.s.). At week 12, 84.8% patients in group 4-week achieved clinical cure with a significant difference compared to groups 1- and 2-week, 54.3 and 60.5%, respectively (P < 0.01). Adverse reactions were present in 4.8, 6.8 and 10.9% of patients in groups 1-, 2- and 4-week, respectively. terbinafine was not associated with clinically relevant increases in liver function tests. CONCLUSIONS: Terbinafine is an effective, well tolerated and safe antifungal agent for the treatment of Tinea capitis in children. The shorter duration of treatment resulted in lower cure rates. However, it is important to note that depending on the severity of the disease, a 1-week-only treatment can also be effective in this indication.

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.

Rhinofacial zygomycosis caused by Conidiobolus coronatus. A case report.

A case of rhinofacial zygomycosis with of years duration, caused by Conidiobolus coronatus is described. The patient, a 72-years-old woman, presented with a bilateral distortion of the subcutaneous tissue and disfigurement of the face. Treatment with ketoconazole and potassium iodide did not prevent several relapses. At present she is still under treatment with fluconazole with clinical healing. Histopathological and mycological examination confirmed the dermatological diagnosis. An increasing number of cases of zygomycosis caused by fungi of the order Entomophthorales have also been reported in the Northern and Northeastern States of Brazil.

Treatment of chromomycosis by cryosurgery with liquid nitrogen: a report on eleven cases.

Cryosurgery with liquid nitrogen was used to treat 11 cases of chromomycosis, 5 with localized lesions and 6 with generalized ones. Freezing time varied from 30 seconds to 4 minutes and the number of cycles from 1 to more than 40. All 5 cases with localized lesions responded extremely well to treatment, with no relapse for up to 53 months. Three patients with generalized lesions attained clinical and mycologic remission for up to 26 months, while 3 had significant improvement without cure. Cryosurgery with liquid nitrogen is therefore an effective treatment for chromomycosis, especially for cases presenting with localized lesions.

Evaluation of serological diagnostic indices for mucocutaneous leishmaniasis: immunofluorescence tests and enzyme-linked immunoassays for IgG, IgM and IgA antibodies.

The sensitivity, specificity, positive predictive value, negative predictive value, and efficiency of immunofluorescence (IF) and enzyme-linked immunoassays (ELISA) for IgG, IgM and IgA antibodies were assessed on sera from mucocutaneous leishmaniasis patients and controls. The sensitivity of the IgG-ELISA test was 93.3% with 95% confidence interval higher than what could be due to a random test not associated with the disease. The specificity of all tests, except the IgM-ELISA, gave indices that could not have been due to chance. The IgG-ELISA and IgG-IF had the highest positive predictive value and the kappa statistic showed that the strength of agreement between the disease and the test was strongest for IgG-ELISA. The IgG-ELISA had a negative predictive value with 95% confidence limits that were not due to chance alone. Efficiency was highest for IgG-ELISA and IgG-IF. These results were obtained using sera from patients with severe or long-standing disease and from controls in whom the disease was ruled out by a negative Montenegro skin test. In field surveys where the differences between cases and controls are less easy to define the diagnostic indices of these tests may vary with the disease prevalence.

Treatment of paracoccidioidomycosis, candidiasis, chromomycosis, lobomycosis, and mycetoma with ketoconazole.

The authors present the use of ketoconazole in 27 cases of paracoccidioidomycosis, eight of mycetoma, seven of chromomycosis, four of systemic candidiasis and one of lobomycosis. The drug was administered orally in a dosage of 200 to 400 mg per day within a period of up to 90 days. The results of the treatment for paracoccidioidomycosis were of cicatrization of the cutaneous lesions in three to four weeks in 24 patients and in two, from six to seven weeks. Out of 27 patients, 14 presented pulmonary lesions. The evolution within a 90-day period showed radiological cure in one case, improvement in seven, and unaltered picture in five patients. In one, there was no further control. In the three out of four cases of candidiasis there was clinical and mycological cure and in one case marked improvement. In seven cases of chromomycosis there was marked improvement in two, moderate in four, and slight in one case. There was slight improvement in one case of lobomycosis, and in eight cases of mycetoma moderate improvement in three, slight in three and none in two, but the mycological examinations were still positive. The drug tolerance was excellent.

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.
