ABSTRACT

Se analizan 104 episodios de neutropenia severa ocurridos en 55 pacientes en el período 1989-91 y se comparan con 95 cuadros semejantes ocurridos en el período 1986-88. Las características clínicas de los pacientes en ambos estudios no presentaron diferencias significativas. En el período 1989--91 los episodios de neutropenia fueron más frecuentes en leucemias y linfomas no Hodgkin y se relacionaron con las primeras fases del tratamiento, lo cual coincide con el período anterior. En el 42.4 por ciento no se encontró foco infeccioso clínico ni bacteriología positiva. Destaca un cambio en los gérmenes encontrados, en su mayoría gram (+)(Staphylococcus aureus) y la disminución significativa del foco gastrointestinal. En nuestra revisión se registraron 9 fallecimientos, de los cuales 7 se debieron a su patología de base y sólo 2 casos fallecieron de una sépsis. El uso de esquemas antibióticos preestablecidos mostró una buena respuesta en 73-100 por ciento, resultado superior al estudio anterior. También se observó una disminución significativa de la mortalidad (11,6 por ciento a 3,6 por ciento). Estas observacioes demuestran la importancia y necesidad de tratar a estos enfermos con esquemas preestablecidos, los que por el cambio de flora patógena y la aparición de nuevos antibióticos, deben ser revisados periódicamente

ABSTRACT

This investigation compared the wear resistance of three "improved" resin posterior denture tooth formulations with two conventional products on a mechanical toothbrush abrasion machine. The ability of the teeth to resist this type of abrasion was evaluated by determination of the weight loss during 339 hours of brushing with firm nylon bristle toothbrushes. All brands exhibited negligible loss, with the conventional brands performing better than the "improved" formulations.

ABSTRACT

Se analizan 95 episodios de neutropenia severa, ocurridos en 37 enfermos. De estos episodios 60 fueron febriles. Los pacientes de linfomas no Hodgkin B presentaron un promedio de 2,4 episodios y los de leucemia no linfoblástica uno de 2,3. En cambio, los casos de tumores sólidos y de enfermedad de Hodgkin tuvieron menos de 1 episodio por enfermo. Los episodios se presentaron preferentemente en las primeras fases del tratamiento quimioterápico. En el 56,7% de los pacientes se encontró un foco clínico y/o el estudio bacteriológico fue positivo. Los gérmenes que se encontraron en los hemocultivos positivos, lo que ocurrió en el 18,3% de los casos, fueron en su mayoría Gram (-). En nuestra casuística se registraron 7 fallecimientos (11,6%), de los cuales 4 correspondieron a enfermos con recaídas refractarias; 2 eran casos de leucemias agudas no linfoblásticas en los que no se logró la remisión completa y el último era un linfoma no Hodgkin que tampoco alcanzó la remisión. En el 40% de los pacientes fue necesario modificar el esquema terapéutico, el que actualmente se basa en la asociación de una cefalosporina de 3ra. generación y de un aminoglicósido

ABSTRACT

This paper presents the results of an intradomiciliary procedure for arsenic removal from water, by means of flocculation with ferric sulphate. The reaction was carried out in a specifically designed tank with a manual agitator (reactor) installed in a vertical support. The salts to flocculate were handed in two small envelopes, whose contents were added independently, agitating the water and letting it settle for two to three hours. Water is decanted by opening a faucet connected to the inferior part of the recipient. Ten families of the states of Durango and Coahuila (the Comarca Lagunera) were selected. Samples of water were taken before and after the treatment. In 70 percent of these samples the arsenic removal was total, and in the remaining 30 percent the removal was superior to 93 percent. The arsenic removal of water in the domicile was very effective, for which it is suggested as a palliative method for those groups with higher levels of exposition.

ABSTRACT

Based on the fact that drinking-water is of great significance in the transmission of infectious diseases, the incidence of diarrheal disorders was examined in two cities similar in their demographic composition and in their use of health services, but not in the quality of the drinking-water supply. In Navojoa, a city with high incidence of diarrheal diseases (116/1000 pop. in 1985), high rates of drinking-water contamination with fecal coliforms were found (43% of water samples); on the contrary, in Ciudad Obregón, a city with lower rates of diarrheal diseases (49/1000 pop. in 1985), drinking-water contamination with fecal coliforms was also comparatively lower (only 6% of water samples). These data illustrate the need to promote the implementation of drinking-water treatment in those places with signs of fecal contamination and high incidence of diarrheal diseases. To this regard, the General Direction for Research and Technological Development of the Ministry of Health has promoted the development of a chlorination equipment, useful mainly in rural areas, where biological contamination is usually high. These and similar procedures for water treatment should be considered as effective means to decrease the incidence of diarrheal diseases.
