Análisis de los resultados del examen estatal teórico. Provincia Sancti Spíritus. Curso 1997-1998 / Analysis of the results of the theoretical state examination. Sancti Spíritus province. Course 1997-1998

Se realizó una investigación descriptiva de los resultados obtenidos por los residentes de medicina general integral en el examen estatal teórico en la provincia de Sancti Spíritus, durante el curso 1997-1998. La promoción general en el componente fue de 58,2 %, siendo los municipios de peores resultados Cabaiguán y La Sierpe con 25,0 y 33,3 % respectivamente. El 60 % de las preguntas se comportaron con una dificultad media, evaluándose como difícil el contenido sobre cardiopatía isquémica; el 67 % de las preguntas discriminaron de forma nula, y el 20 % negativamente (asma bronquial, tuberculosis pulmonar y sepsis urinaria) se concluye que el examen teórico a pesar de sus malos resultados, metodológicamente estuvo bien estructurado. Se recomienda analizar multisectorialmente los resultados de la investigación para buscar alternativas de solución.

Clostridios mesófilos en suelos de la Meseta Central de Costa Rica / Mesophilic clostridia from soil of the Central Plateau of Costa Rica

Thirty soil samples from the Central Plateau of Costa Rica yielded 710 isolates of 34 clostridia species. These were Clostridium lituseburense, C. oceanicum and C. sardiniense (100, 73, and 60, respectively). The toxigenic species of the genus were present in at least one sample, except for C. botulinum, C. chauvoei and C. spiroforme. Diversity per sample (4-12 species) exceeded what has been reported in similar studies. No correlation has been found between the presence of a species and soil characteristics (organic matter, type of soil, pH, precipitation, altitude).

Clostridium botulinum en suelos de Costa Rica / Clostridium botulinum in Costa Rica soils

Thirty soil samples from the Pacific Dry Forest, the Caribbean lowlands and the Central Plateau of Costa Rica yielded seven cases with botulinal toxins. Of these, five were type C, one A and one B. Type C samples were from the Dry Pacific coastal area, others from the Caribbean lowlands. C. botulinum was isolated from three out of seven positive soil samples. The main reason for the poor recovery of C. botulinum from toxigenic samples is attributable to a low concentration of spores in the samples, because the toxin detection method required ten bacterial spores. An association was found between the presence of C. botulinum and low contents of organic matter (p < 0.05), but not with pH or soil type (p > 0.05).

Primer aislamiento de Clostridium tetani a partir de suelos de la Meseta Central de Costa Rica / First isolation of Clostridium tetani from soils of Meseta Central, Costa Rica

Clinical evidence has long pointed to the existence of Clostridium tetani in Costa Rica. Thirty soil samples were studied for clostridia, and two yelded sis strains of C. tetani, four of which proved to be toxigenic when mice were inoculated intraperitoneally with the culture supemates. These four isolates could be neutralized when their toxic supemates were admixed with tetanus antitoxin
