Abstract: Lobomycosis or lacaziosis is a chronic granulomatous fungal infection caused by Lacazia loboi. Most cases are restricted to tropical regions. Transmission is believed to occur through traumatic inoculation in the skin, mainly in exposed areas. It is characterized by keloid-like nodules. There are only a few hundred cases reported. The differential diagnoses include many skin conditions, and treatment is difficult. The reported case, initially diagnosed as keloid, proved to be refractory to surgical treatment alone. It was subsequently approached with extensive surgery, cryotherapy every three months and a combination of itraconazole and clofazimine for two years. No signs of clinical and histopathological activity were detected during follow-up.

Resumo A classificação médica (CM) adotada aos nadadores com deficiência visual (DV) não consegue elucidar claramente a influência da perda da visão no desempenho. Em uma pesquisa documental, analisou-se o tempo final de prova dos 50, 100 e 400m livre e a CM (S11, S12 e S13) de nadadores nacionais (n = 40) e internacionais (n = 72) de elite. Utilizou-se o teste de Kruskal-Wallis e a correlação de Spearman, com 95% de confiança (P < 0,05) e o tamanho do efeito d de Cohen foi calculado. Verificou-se um grande efeito da CM no tempo final de prova dos 50m (P = 0,034; d = 1,55) para atletas nacionais e dos 50m (P = 0,001; d = 2,64), 100m (P = 0,001; d = 3,01) e 400m (P = 0,001; d = 2,88) para atletas internacionais. As classes S12 e S13 foram mais rápidas comparadas à classe S11 em todas as provas internacionais, mas apenas nos 50m nas provas nacionais (P < 0,05). Foram encontrados fortes relacionamentos negativos entre o tempo final de prova e a CM para os atletas internacionais (Rho de Spearman ≥ 0,78). Houve uma significativa influência da CM no desempenho de nadadores nas provas do nado livre, especialmente em nadadores internacionais. Assim, ter um resíduo visual parece ser o suficiente para que os nadadores com baixa visão, nas classes S12 e S13, adquiram performance semelhante.

Abstract The medical classification (MC) adopted for swimmers with vision visual impairment (VI) does not clearly elucidate the influence of vision loss on performance. In a documentary research, the final time in the 50-, 100- and 400-m freestyle events and MC (S11, S12 and S13) of national (n = 40) and international (n = 72) elite swimmers was analyzed. The analysis was performed using the Kruskal-Wallis test and Spearman’s correlation with 95% confidence (P < 0.05) and Cohen’s d was calculated. There was a large effect of MC on the final time in the 50-m (P = 0.034, d = 1.55) for national athletes and in the 50-m (P = 0.001, d = 2.64), 100-m (P = 0.001, d = 3.01) and 400-m (P = 0.001, d = 2.88) for international athletes. S12 and S13 classes were faster compared to S11 class for all international events, but only in the 50-m for the national event (P < 0.05). It was found a strong negative relationship between the final time and MC for international athletes (Spearman’s Rho ≥ 0.78). There was a significant influence of MC on the performance of swimmers in freestyle races, especially in international swimmers. Thus, having a visual residue seems to be sufficient for S12 and S13 swimmers to achieve similar performance.
