ABSTRACT

La esporotricosis representa la micosis profunda del hombre más frecuente en Uruguay y tiene como medicación habitual la administración oral de yoduro de potasio. Sin embargo, lahipertermia local es también frecuentemente usada con éxito de acuerdo a numerosos trabajosinternacionales. Objetivos: 1) recordar las primeras investigaciones científicas demostrativas del efecto de la temperatura ambiental sobre laesporotricosis experimental en animales de laboratorio y su consecuencia inmediata, la aplicación exitosa de la termoterapia local en un caso humano realizada en Uruguay en 1962; 2) revisar la literatura sobre ensayos clínicos posteriores de termoterapia local en la esporotricosis humana en otros países y los resultados obtenidos con el empleo de diferentes diseños terapéuticos; 3) analizar los principales mecanismos biológicos de acción de latermoterapia local en el proceso de curación de las lesiones de acuerdo a los resultados de múltiples investigaciones.La principal conclusión del mismo es la aceptación universal actual de la eficacia e inocuidad de la termoterapia local en la enfermedad cuyas principales indicaciones son la intolerancia a los yoduros y situaciones fisiológicas especiales, como el embarazo, en queaquellos están formalmente contraindicados. El calor local es aconsejado asimismo como tratamiento complementario de los yoduros cuando son bien tolerados o del itraconazol conel fin de acortar el lapso requerido para la curación. De acuerdo con toda la investigación realizada hasta el presente por diferentes autores...


Sporotricosis represents the most frequent human deep mycosis in Uruguay, and it is usually treated with oral potassium iodide. However, local hyperthermia is also frequentlyused successfully according to several international studies. The present study aims at the following objectives: 1)to go over the first scientific research that proved the effect of environmental temperature on experimentalsporotricosis in laboratory animals, and its immediate consequence on the successful application of local thermotherapy in a human case in Uruguay, back in 1962; 2)to review literature on subsequent clinical trials on local thermotherapy to treat human sporotricosis in other countriesand the results obtained in the application of different therapeutic designs; 3) to analyse the main biological mechanisms of action for local thermotherapy in the process of healing lesions according to the results obtainedin multiple research studies. The main conclusion is the current universal acceptance of the effectiveness and harmlessness of local thermotherapyon the disease, whose main indications are iodine intolerance and special physiological situations, such as pregnancy, when they are contraindicated. Local heat is advisable as a complementary treatment to iodinewhen well tolerated or to itraconazole, with the purpose of shortening the period needed for curing. According to research conducted by different authorsuntil today, local heat therapy to cure sporotricosis would result from several biological mechanisms. Among them,the direct inhibition of Sporothrix schenckii parasite cells in tissues...


A esporotricose é a micose profunda do ser humano com maior freqüência no Uruguai sendo tratada habitualmentecom iodeto de potássio. No entanto a hipertermia local também é utilizada como está descrito em numerosostrabalhos internacionais. Os objetivos deste trabalho são: 1) rever as primeiraspesquisas científicas que descreveram o efeito da temperatura ambiental sobre a esporotricose experimental e suaconseqüência imediata - a utilização bem sucedida da termoterapia local em um caso humano no Uruguai em 1962;2) rever a literatura sobre estudos clínicos posteriores sobre a utilização da termoterapia local no tratamento da esporotricose humana em outros países e os resultados obtidos utilizando diferentes esquemas terapêuticos; 3)analisar os principais mecanismos biológicos da ação da termoterapia local no processo de cura das lesões deacordo com os resultados obtidos em diferentes estudos. A principal conclusão é a aceitação mundial da eficáciae inocuidade da termoterapia local nesta doença cujas principais indicações são a intolerância aos iodetos e situaçõesfisiológicas especiais como a gravidez, nas quais os iodetos estão especialmente contraindicados. O calortambém esta indicado como tratamento complementar ao tratamento com iodetos quando estes são bem toleradose o tratamento como itraconazol para reduzir o tempo necessário para a cura.De acordo com as pesquisas realizadas por diferentes autores até o momento, a cura pela termoterapia seria resultadode diferentes processos biológicos. Entre eles a inibição direta das células parasitarias de Sporothrix schenckiinos tecidos, a hiperleucocitose focalizada...

ABSTRACT

A case of mycotic bovine nasal granuloma in a 10 year-old Jersey cow, produced by Drechslera halodes is presented. Histopathological sections showed abundant hyaline and pigmented extra and intracellular fungal structures together with a polymorphic cellular granuloma formed by neutrophils, lymphocytes, plasmocytes, histiocytes and giant cells of the Langhans type. It is the first case of mycotic bovine nasal granuloma recognized in Uruguay although this disease seems to be frequent according to the opinion of veterinarian specialists. Another similar clinical case also in a Jersey cow from the same dairy house with an intense cellular infiltrate rich in eosinophils without granulomatous image, together with extracellular hyaline and fuliginous fungal forms, is also referred for comparative purposes. Geotrichum sp. was isolated. The need of an early diagnosis and treatment of the disease is stressed

ABSTRACT

The present status of human ectoparasitoses in Uruguay is analized with the main purpose of performing in the future, comparative studies in the region. After classifying ectoparasitores in temporaries and permanents, comments are made on particular clinical and epidemiological aspects of some of them. For remarking: the high prevalence of pediculosis capitis and scabies; the frequent observation of cutaneous myiasis by dermatobia hominis with a very interesting modification of the geographical national distribution of the fly and the presence of an endemic area of creeping eruption by ancylostoma braziliense an A. caninum in the north of the country
