Contaminação do solo do Estado do Rio de Janeiro pelo Clostridíum tetani: Estudo preliminar das relações entre a composição química do solo e a presença do bacilo

Os autores apresentam os resultados preliminares da relação entre o grau de contaminação pelo C. tetani e a composição química de 82 amostras da camada superficial do solo do Estado do Rio de Janeiro, colhidas ao acaso. Não encontram relação importante entre a presença do bacilo e a concentração de potássio, magnésio, fósforo, alumínio, carbono e o pH do solo. As amostras ricas em cálcio, porém, apresentaram maior positividade. Devido à heterogeneidade das amostras, possibilitando a influência de outros fatores nos resultados, os autores pretendem estudar o assunto em amostras mais selecionadas.

A Nonhealing Ulcer on the Nose. A Case Report

Dermatitis artefacta is a disease characterized by self-inflicted skin lesions as the result or manifestation of psychiatric disorders or specific stress situations. Clinical manifestations range from superficial erosions to deep wounds. Because of its rarity and the polymorphism of the lesions, dermatitis artefacta is often a challenge for the clinicians. This report presents the case of a 62-year-old woman who had an ulcer of the nose lasting for three years caused by digital manipulation. Early recognition of dermatitis artefacta is difficult but avoids unnecessary treatments. A multidisciplinary approach to this entity is necessary to obtain the best results.

Long-Term Recurrence of Nonmelanoma Skin Cancer after Topical Methylaminolevulinate Photodynamic Therapy in a Dermato-Oncology Department

BACKGROUND: Most available studies on the efficacy of topical photodynamic therapy focus on short-to medium-term results. Long-term data are scarce. OBJECTIVE: To evaluate the long-term efficacy of photodynamic therapy with topical methylaminolevulinate to treat Bowen's disease and basal cell carcinoma in the clinical practice setting of a dermato-oncology department. METHODS: The study included patients diagnosed with Bowen's disease or basal cell carcinoma, and who received photodynamic therapy from 2004 to 2008. Treatment protocol and clinical follow-up were standardized. The primary endpoint was clinically observed recurrence in a previous photodynamic therapy-treated area. Descriptive and survival analyses were performed. RESULTS: A total of 31 Bowen's disease lesions and 44 superficial basal cell carcinoma were treated, with a median follow-up of 43.5 months. Recurrence was observed in 14 Bowen's disease lesions (53.8%) and in 11 superficial basal cell carcinoma (33.3%). Significantly higher estimates for recurrence rates were found in patients with Bowen's disease (p=0.0036) or those aged under 58 years (p=0.039). The risk of recurrence was higher in patients with Bowen's disease than in those with superficial basal cell carcinoma and younger patients. CONCLUSIONS: Recurrence should be considered when choosing to treat non-melanoma skin cancer with photodynamic therapy. Younger age and Bowen's disease were independent predictors for long-term recurrence, suggesting the need to establish an extended period of follow-up for this subset of patients.

Attempts using cryotherapy to achieve more rapid healing in patients with cutaneous leishmaniasis due to L. braziliensis braziliensis

The use of cryotherapy as an adjunct to systemic antimonial therapy (Clucantime) was studied in 17 patients with a total of23 skin lesions of leishmaniasis in an area where L. braziliensis braziliensis is the species in circulation. Cryotherapy did not speed healing and has been discarded as an auxiliary therapeutic measure in our practice. However this technique may be suitable for species o/Leishmania causing more limited superficial lesions in man without the danger of metastasis.

Cardiac plexus of dogs experimentally infected with Trypanosoma cruzi: inflammatory lesions and quantitative studies

Qualitative and quantitative aspects of the superficial and profound cardiac plexus of dogs experimentally infected with Be-62 and Be-78 strains of Trypanosoma cruzi were studied. Animals were autopsied in the acute phase of infection. The inflammatory process, lesions and number of parasites were more intense and frequent in animals infected with the Be-78 strain than in those infected with Be-62. Despite this, no statistically significant differences could be found between the number of neuron bodies in the ganglia of infected and control dogs.
