[Prognosis determination in patients with malignant lymphoma].

One hundred and eight patients with malignant lymphoma were evaluated for pretreatment characteristics as potential predictors of response and survival. Age, sex, lymphocytes, lactic dehydrogenase, clinical evolution, histology, stage and initial symptoms provided the basis for a prognostic classification. The results show that the classification gives good information as the survival curves are clearly separated into three prognostic groups. Implications of the classification in therapy planning are briefly discussed.

[Death caused by acute diarrhea in children: a study of prognostic factors].

OBJECTIVE: To identify prognostic factors of death due to acute diarrhea related to the process disease-health care-death in the State of Tlaxcala, Mexico. MATERIAL AND METHODS: A case-control design was used. Cases were defined as children who died between the ages of seventy-two hours and five years between 1992 and 1994. An event of acute diarrhea was the main cause of death stated in the death certificate. Case ascertainment was done through the verbal autopsy method. Controls were children who had suffered acute diarrhea with at least one sign of dehydration or alarm and had overcome the diarrheal episode. Controls were randomly selected from the population at large and were matched by age with cases. RESULTS: One hundred and six cases and the same number of controls were taken. Using a logistic regression procedure in which severity of illness and days of evolution were controlled for, the prognosis-worsening predictors were: visit provided by private physician (OR 8.9); inappropriate treatment (OR 10.4); a working mother (OR 8.7); mother's lack of knowledge to identify dehydration signs (OR 8.1); siblings' malnutrition (OR 28.2); and malnutrition prior to the diarrheal event (OR 7.5). CONCLUSIONS: These findings suggest that factors worsening the outcome of the diarrheal episode are: malnutrition, the inappropriate treatment provided by private physicians, and the deficient household care of the diarrheal episode.

[Characteristics associated with under-registration of children's deaths in the state of Guerrero, Mexico].

OBJECTIVE: To estimate the frequency of under-registered children deaths in rural areas and to identify associated characteristics. MATERIAL AND METHODS: The study was conducted in three stages. In the first, three strata of communities were formed according to the number of inhabitants; then a representative number of villages was randomly selected from each stratum. A census was made in each village to determine the deaths occurred between June 1993 and July 1994. In the second stage, the verbal autopsy method was used with the mothers of the dead children to determine the cause of death and investigate the study variables. In the third stage, registration of death was verified through the death certificates. RESULTS: An under-registration frequency of 68.9% was found; in communities of less than 500 inhabitants under-registration reached 73.2% and in larger communities it was 60.5%. Characteristics associated to under-registration were the lack of birth and death certificate, age younger than one month, lack of information on the concept and purpose of a Public Registration Office, distance from the Public Registration Office and to the doctor of more than 30 minutes, and community smaller than 1,000 inhabitants. CONCLUSIONS: A modification in the current organization of the death registration procedure is proposed and the use of a birth certificate designed by the National Health System.

[Mortality for diarrheic disease in Mexico: problem of accessibility or quality of care?].

OBJECTIVE: To evaluate the access to health services and the process of care provided to children under five years old who died from acute diarrhea (AD). MATERIAL AND METHODS: In four states of Mexico, a cross-sectional study was carried out. Deaths from AD that occurred in the lapse of one year were included. Information about clinical characteristics of the illness, process of care and access to the health facilities were obtained through verbal autopsy. Descriptive analysis and comparison of data between rural and urban communities were performed. RESULTS: Five-hundred and fifty three deaths were analysed. Most of the children were not enrolled in a public care health system. The main children's characteristics were the following: residence in rural communities; age less than one year; died at home or had short illness duration. Geographic and economic access barriers were identified in rural areas. Oral rehydration salts were provided as a part of household treatment in about 75% of children. 20% of them received non-medical care, specially from traditional healers. Primary medical care was provided to 60% of cases; the drawbacks of the process were related to a high rate of medication prescription, lack or referral to hospital, and lack of recommendation for a new visit in presence of alarm signs. Public physicians and those from rural communities prescribed oral rehydration therapy in a greater proportion. CONCLUSIONS: The problem of access to health services in rural communities was confirmed. However, low quality of care provided by primary level physicians was found in both rural and urban areas. We propose the creation of clinical teaching centers to improve the quality of the process of medical care as a strategy to decrease mortality due to AD.

Acute spinal cord and head injury: case report and discussion of cardiac, respiratory and endocrine abnormalities.

We report a male patient who after a fall suffered high cervical spinal cord and head (cerebral) injuries. These injuries led to spinal shock, marked sinus bradycardia and asystolic cardiac and respiratory arrests, recalcitrant central traumatic diabetes insipidus, and death within approximately seven weeks. Temporary transvenous cardiac pacing proved useful in the management of this patient.
