Granuloma facial: A proposito de dois casos

Granuloma faciale is a benign and rare disease restricted to the skin. Its etiopathogenesis is not related to systemic granulomatous and eosinophilic diseases. Two adult patients with reddish-brown lesions on the facial are reported. Among the treatments used, the more consistent results were observed with intralesional triamcinolona (Case 1) and with CO2 Laser (Case 2), with clear advantage of the laser therapy. The histopathology and the therapeutic options are discussed.

Sindrome das bandas ou constricoes amnioticas: Relato de caso

The authors present a case of constriction band syndrome in a 20-year-old male. There were constriction rings in the interphalangeal joints of hands and in the thigh, shortening of the lower limb and atrophic left gastrocnemius muscle. These findings belong to the described syndrome, which is uncommon and has no genetic implication. Personal antecedent: convulsive syndrome and corrective surgery for congenital bent foot.

Penfigo foliaceo no Hospital das Clinicas da Faculdade de Medicina de Botucatu, SP

BACKGROUND - Pemphigus foliaceus is an autoimmune bullous disease that is endemic in Brazil and in other South American countries such as Paraguay, Bolivia, Peru and Colombia. OBJECTIVES - To compare the observed clinical and epidemiological data with those referred in the literature. METHOD - Retrospective study in patients with pemphigus foliaceus admitted to and treated at University Hospital of the School of Medicine of Botucatu, SP, Brazil, from 1976 to 1993, analyzing the following variables: age, sex, race, origin and onset of disease. RESULTS - From 1976 to 1993, 63 patients were treated, with an average of 3.7 cases/year. Patients within the age range of 20 to 60 years old were the most affected. Most of the patients were white, females being slightly more affected than males. The majority of male patients were rural workers. Some towns presented higher incidence of cases. Most of the patients from rural areas became sick mainly in summer and in autumn. Occurrence of similar cases was observed in blood-related family members and neighbors. CONCLUSIONS - Clinical and epidemiological data were similar to those referred in the literature.

Fatoriais fixos desbalanceados: Uma análise mal compreendida

Few users of statistical packages are capable of analyzing unbalanced factorials properly, because introductory textbooks do not discuss this topic in detail. The present article is directed to agriculture researchers, with the purpose of clarifying the differences among several widely used programs. It shows how to test useful hypotheses about population means in models having qualitative and quantitative factors. The paper emphasizes the pitfalls of blindly applying packages without prior knowledge of the hypotheses being tested.

Paracoccidioidomycosis: Survey and clinical aspects from the Department of Dermatology of the School of Medicine of Botucatu (Sao Paulo - Brazil)

Background - Paracoccidioidomycosis is the most frequent among the systemic mycoses in Brazil. Objective: To study the cases of paracoccidioidomycosis diagnosed from 1976 to 1996 at the Department of Dermatology of the School of Medicine of Botucatu. Methods - Descriptive study obtained from specific protocols comprising anamnesis, clinical- dermatological-laboratorial examination, treatment and follow-up of the patients. Results - Paracoccidioidomycosis was diagnosed in 1.04% of the dermatologic outpatients assisted from 1976 to 1996. In 315 cases, 89.8% were male, 61.9% were over forty and 53.7% were rural workers. The complaints were related more to oropharyngolaryngeal (53.6%) or cutaneous (23.8%) lesions or adenopathy (10.2%). Seventy patients had already been treated in other health services. The chronic multifocal clinical from was the most common: 80.6% of the cases, followed by the acute-subacute (juvenile type) 15.5%. The disease was pulmonary in 80.0%, oropharyngolaryngeal in 69.2% and cutaneous in 45.7%. Th treatment: Amphotericin B in 146 patients, Ketoconazole - 88, Itraconazole - 56, Sulfonamide derivatives - 146 and Terbinafine in 3. The lethality index resulting from the disease or its treatment was 2.0%. Conclusions - The high number of cases, showing the regional relevance of the disease and the high percentage of tegumentary complaints and the high number of relapsing are remarkable.

Human sporotrichosis: Transmitted by feline

The authors present two cases of human sporotrichosis, the lymphangitic and the fixed cutaneous form, observed in the owners of an infected domestic cat. Feline sporotrichosis has been related with higher frequency and shows zoonotic significance due to inter and intraspecies transmission risk. This is thought to occur as consequence of the high number of fungi in cutaneous lesions of this animal species.

Paracoccidioidomicose

The aspects related to the epidemiology, pathogenesis, clinical classification, clinical manifestations and treatment of Paracoccidioidomycosis, are presented. The disease is caused by Paracoccidioides brasiliensis and is the most frequent and the most important systemic mycosis in the South America, specifically in Brazil, Argentina, Colombia and Venezuela. Because of the high frequency of cutaneous-mucosal lesions presented by the patients, the potential severity of the disease and the socio-economic consequences to the patient, it is very important for a drematologist to be qualified to precisely diagnose the disease and render proper care.

Tratamento da leishmaniose cutanea difusa (LCD) com a associacao antimoniato-N-metilglucamina (Glucantime®) e sulfato de paramomicina (Gabbrox®)

Diffuse cutaneous leishmaniasis (DCL) is a rare form of tegumentary leishmaniasis (TL) and 350 cases have been reported world wide. Presently in Brazil, there were 31 cases reported corresponding to 8.9% of the world cases. The state of Maranhao contributed with ten cases (32.3%) of national reports. Recently the authors had opportunity to follow two new cases of DCL, both from the countryside of that state totaling 12 cases. The parasite Leishmania L. amazonensis was incriminated in the disease, confirming the available data as being the unique species to produce DCL in this state. The therapy associating meglumine anthimoniate with paramomicine sulphate (Gabbrox®) during 90 days, showed good tolerance and favorable response, being another option for fills form of DCL that constituted a challenge to science so far.

Kras oncogene analysis of non-melanoma skin tumors in Southeastern Brazil

Skin cancers are the most common human malignant neoplasia and their incidence is growing, chiefly in tropical countries. There is evidence that ultraviolet (UV) radiation present in sunlight is important for genetic damage. Mutations due to such damage could be responsible for alterations in oncogenes and tumor suppressor genes. Recent studies have reported remarkable differences in mutation frequency of the RAS proto-oncogene in non-melanoma skin cancers. These findings may reflect differences in the molecular epidemiology of cutaneous tumors found in geographical areas with diverse sun exposure and ethnical origins of their populations. Our study proposed to perform molecular analyses of skin tumors on patients living in southeastern Brazil, in areas with high levels of sun exposure. DNA from eight solar keratose (SK), 26 basal cell carcinomas (BCC) and 19 squamous cell carcinomas (SCC) was submitted to PCR-SSCP analysis for codons 12, 13 and 61. Contradicting other authors, we found no mutations in codons 12,13 but detected two BCCs and one SCC with a mutation in codon 61. These findings suggest that the activation of KRAS oncogene may contribute to the pathogenicity of cutaneous lesions in southeastern Brazil.

Hidrocistoma écrino e apócrino na pálpebra - Casuística na Faculdade de Medicina de Botucatu- São Paulo

Background - Hidrocystomas ecrine and apocrine may be observed in the eyelids. Objective - The purpose of this study was to observe the occurrence of eyelid hidrocystoma (eccrine or apocrine), as well as the relation between clinical and histopathological diagnosis. Patients and Methods - 42 patients were selected, with a total of 52 lesions, attended between January 1990 to April 1999, at the Botucatu Medical School, with diagnosis of hidrocystoma confirmed by histopathology diagnosis. Result - Hidrocystoma occurred in 0.07% of patients undergoing lesion removal during this period. Eccrine and the apocrine hidrocystoma were frequently observed in female patients, aged over 40 years. The clinical picture ranged from about 1 to 5 years. The lesions were mainly located in the lower eyelid and presented as a single lesion. The clinical diagnosis agreed with the histopathological diagnosis in 67.31% of the apocrine hidrocystomas, and 9.62% of the eccrine hidrocystomas. Conclusions - Apocrine hidrocystoma was the most frequently observed eyelid hidrocystoma. The correlation between clinical and histopathological diagnosis was higher for apocrine hidrocystomas.

Retalho de rotação para defeitos da asa nasal

Surgical defects of the alar lobule can be difficult to repair with functional and aesthetically desirable results. Skin grafts are smoother and paler than the nasal skin. Flaps from the cheek and proximal nose can bridge the alar crease, resulting in obstruction. The authors describe a technique to repair nasal ala defects, with maintenance of the cosmetic unit, without airflow disturbance.
