Diarrhoeal diseases in the White Mountain Apaches: clinical studies.

Acute diarrhoeal diseases continue to be a major health problem in certain underprivileged populations in the United States, including native Americans living in reservations. To describe the features of patients with diarrhoeal diseases requiring medical care, those attending the medical facilities of the Fort Apache Indian Reservation, Whiteriver, Arizona, were studied during 1981-1985. Clinical and aetiological information was obtained on 535 patients which constitute a 20% sample of those attending the outpatient clinic and all 386 patients who required 550 hospitalizations. Rotavirus, enterotoxigenic Escherichia coli, and Shigella were the most common aetiologic agents, a pattern similar to that seen in the developing countries. The clinical features of diarrhoeal illness and the frequent associated occurrence of acute respiratory symptoms, however, were remarkably similar, regardless of aetiology.

Diarrhoeal diseases in the White Mountain Apaches: epidemiologic studies.

Acute diarrhoeal disease in children is known to be a major public health problem among native Americans living in reservations in the southwestern part of the United States. This study was undertaken to describe the epidemiology and causative agents of diarrhoea more completely, with the expectation that this information may help in the ultimate control of the disease in this population. Three interrelated epidemiologic studies were carried out in the White Mountain Apache Tribe, Whiteriver, Arizona, during 1981-1985: a three-year longitudinal study on a cohort of 112 newborns, a longitudinal two-year study in a cohort of 200 families, and a case-control study on 1,072 children with diarrhoea attending a medical facility. Both epidemiologic and microbiological patterns of diarrhoeal disease were found to be very similar to those seen in developing countries, indicating the need for basic improvements in sanitation and hygiene in this population.

APACHE II score and primary liver cancer history had risk of hospital mortality in patients with pyogenic liver abscess.

BACKGROUND: The Acute Physiology and Chronic Health Evaluation II classification system has been extensively used for predicting the patient mortality in various diseases. However, its utilisation on the pyogenic liver abscess has not yet been well studied. AIMS: The purpose of this study was to validate this system on this high death rate disease. PATIENTS: A retrospective study was conducted to assess 314 patients with pyogenic liver abscesses admitted to tertiary medical centre in past 12 years. METHODS: The outcome measurement was the in-hospital mortality. A multiple logistic regression model was used to assess the association between mortality and Acute Physiology and Chronic Health Evaluation II score while controlling for the potential confounding factors. RESULTS: The overall in-hospital mortality was 8.3%. The mean Acute Physiology and Chronic Health Evaluation II score of the expired patients was higher (P<0.0001). The mortality rate increased rapidly when Acute Physiology and Chronic Health Evaluation II score >or=15. After controlling for the potential confounding factors, patient with high admission Acute Physiology and Chronic Health Evaluation II score >or=15 had a higher chance of in-hospital mortality (P<0.01). In addition, the primary liver cancer history is also a risk factor (P=0.03). CONCLUSIONS: The Acute Physiology and Chronic Health Evaluation II score and the primary liver cancer history predict the in-hospital mortality of the pyogenic liver abscess patient.

[Control of arterial hypertension based on self-measurement of blood pressure: APACHE study].

BACKGROUND AND OBJECTIVE: The objective was to analyze the control rates of hypertension in a large group of hypertensives on antihypertensive treatment by means of blood pressure (BP) self-measurements, and to assess if the degree of control at early morning hours differs from that at the rest of the day. PATIENTS AND METHOD: 9,227 subjects [4,398 men, mean age 61.0 (11.4) yr, body mass index 28.4 (4.1) kg/m2] who had hypertension and were on antihypertensive treatment at least during one month before were included. Patients were recruited from primary care physicians. After receiving training, six BP measurements over one day were performed by means of a Braun Precision Sensor BP 2550 monitor, which measures BP at wrist level. RESULTS: Whole day SBP and DBP averages were 138.4 (16.5) mmHg and 85.4 (8.7) mmHg, respectively. Both SBP and DBP in early morning hours were significantly higher than those observed before lunch or before dinner. The percentage of subjects with BP < 130/80 mmHg was 15.5%; 15.4% had SBP < 130 mmHg but DBP > 80 mmHg, and 2.0% had DBP < 80 mmHg and SBP > 130 mmHg). Control rates were lower at early morning hours and in men. CONCLUSIONS: By using BP self-measurement, control rates of hypertension are low, especially in early morning hours as compared to the rest of the day. New strategies are needed to further increase the control of hypertension.

A comparison of ICU mortality prediction using the APACHE II scoring system and artificial neural networks.

The aim of this study was to compare the ability of artificial neural networks and the Acute Physiology and Chronic Health Evaluation II score to predict mortality in adult intensive care units. The same physiological variables were used in both predictive models to predict hospital mortality from a data set of 8796 patients collected from 26 adult intensive care units in the United Kingdom and Ireland as part of the Intensive Care Society study. The results from the two models were compared with the actual outcome. The overall prediction accuracy and the overall goodness-of-fit of all the models were assessed. Both predictive models showed similar goodness-of-fit and prediction discrimination. The overall predictive and classification performance of the artificial neural network developed matched and in some aspects was better than that of Acute Physiology and Chronic Health Evaluation II.

Evaluation of predicted and actual length of stay in 22 Scottish intensive care units using the APACHE III system. Acute Physiology and Chronic Health Evaluation.

The most recent edition of the Acute Physiology and Chronic Health Evaluation provides a prediction of intensive care unit length of stay in addition to the probability of hospital mortality. Intensive care length of stay is an important determinant of intensive care costs and may be an important indicator of quality of care. Data were collected from 22 Scottish intensive care units over a 2-year period to allow comparison of actual intensive care unit length of stay with that predicted by the Acute Physiology and Chronic Health Evaluation III system. Correlation between actual and predicted stay for individual patients was poor. However, performance of the model for patients, grouped either by predicted length of stay or by intensive care unit, indicated that the model stratified patient groups appropriately while demonstrating a consistent bias. Length of stay in Scottish intensive care units was found to be consistently lower than that predicted by a model which is based on intensive care practice in the USA. Variations in severity of illness in intensive care unit populations cannot readily explain differences in intensive care unit length of stay. The availability of a model capable of predicting length of intensive care stay, based on data reflecting practice in the UK, would compliment current methods of assessing effectiveness of intensive care.

Severe acidosis in patients taking metformin--rapid reversal and survival despite high APACHE score.

BACKGROUND: Metformin has been shown to reduce complications and mortality from Type 2 diabetes mellitus, and is increasingly used to treat this condition. This agent is, however, associated with a rare but serious risk of lactic acidosis. CASE REPORT: We present cases of 10 patients with Type 2 diabetes mellitus who developed acute renal failure and severe lactic acidosis. Despite the severity of their illness, all patients but one survived. CONCLUSIONS: The increasing prevalence of Type 2 diabetes and its treatment with metformin might result in more cases of lactic acidosis. However our case report demonstrates that early and aggressive treatment with haemofiltration can improve outcomes even in the presence of severe acidosis.
