The postoperative course of 159 patients with early gastric cancer operated on between 1974 and 1987 was followed for a median of 7.3 years. The cumulative 10-year survival rate(s.e.) calculated using follow-up data to the end of 1989 was 90.6(2.7) per cent excluding operative death and that from causes other than gastric cancer, or 86.3(3.0) per cent when operative mortality was included. The overall 10-year survival rate(s.e.) was 77.3(3.7) per cent. Univariate analysis showed a significant difference in survival rates between cancers confined to the mucosa and those with submucosal invasion (P = 0.02), between patients with and without lymph node metastases (P = 0.05) and between those < or = 50 and > 50 years of age (P = 0.02). Using Cox multivariate analysis and a stepwise procedure for eight variables (sex, age, depth of invasion, lymph node metastases, presence of ulceration, location, histological type, type of surgery), age and histological type had the most significant effect on survival. Seven operative deaths were recorded. Eleven patients died from recurrent cancer and one is still alive with a gastric remnant recurrence. Other causes of death were metachronous primary cancer (six patients), cardiovascular disease (two), pneumonia (three), sepsis (one) and car accident (one). Although the prognosis of early gastric cancer is relatively good in western countries, patients should be carefully followed over a long period for late recurrence and for metachronous cancer, which has a high incidence.

From 1966 to 1989 a total of 1,830 cases of bacterial meningitis were recorded at the Department of Infectious Diseases, Rigshospitalet, Denmark. Staphylococcus aureus meningitis accounted for 44 (2.4%) of these cases. Among these, 28 cases were classified as community-acquired S. aureus meningitis. The mortality rate for these cases was 43%. A retrospective study of clinical features and parameters in these community-acquired cases showed the following conditions to be associated with a high mortality risk: advanced age, an underlying condition requiring artificial ventilation, cardiovascular disease and immune deficiencies. At admission, more than 75% of the patients had fever, nuchal rigidity and decreased consciousness. In 57% of cases the focus for the S. aureus infection was endocarditis, pneumonia or skin infections. All the patients had complications due to the meningitis, the major one being insufficient respiration. Autopsy performed in 9 of the 12 fatalities showed endocarditis in 5, pneumonia in 4, and pyelonephritis in 2. All of the brains examined at autopsy showed cerebral and subarachnoid hemorrhage.

Cause of death among 917 of the 959 subjects in a population-based incidence cohort with Alzheimer's disease (AD) during the years 1960 to 1984 was compared to that of an age- and gender-matched control group (n = 703). In general, a summary of the diagnostic codes entered anywhere on a death certificate suggests that control subjects had more cardiovascular disease and neoplasms than did patients, while patients more often had a diagnostic code of bronchitis/pneumonia (P < 0.01). By logistic regression, this difference remained statistically significant after adjusting for age and gender.

The present study reviews 876 consecutive coroner's autopsies performed in the Department of Pathology, University College Hospital, Ibadan over a two-year period (1 February 1991 to 31 January 1993). The hospital autopsy rate during the study period was 36.2%, and 62.5 per cent of these post-mortems were medico-legal cases. The most common indications for coroner's autopsies were sudden natural deaths (55.6%), followed by accidental deaths (35.3%). The proportions of maternal (4.3%), homicidal (3.1%) and suicidal (0.3%) deaths were much lower. The male to female ratio was 1.7 to 1. Ninety-one (10.4%) of the cases fell within the paediatric age group and the peak age incidence for these cases was in the 5-14 years age group. The remaining 785 (89.6%) cases were adults and the peak age incidence for these cases was in the fourth decade of life. The most common cause of sudden natural death was cardiovascular disease, of which hypertension constituted the majority of cases. Other major causes of sudden death included pneumonia, meningitis, typhoid fever and neoplastic diseases. Road traffic accidents accounted for 78 per cent of accidental deaths followed by falls (13.3%) and burns (4.6%). Abortions, post-partum haemorrhage and eclampsia were the major causes of maternal deaths in the present study. Homicidal deaths were eight times more frequent in male than female victims and the commonest mode of death was gunshot injuries. Suicidal deaths remain extremely uncommon in African patients, as confirmed by our study.

The postoperative course of 172 patients with early gastric cancer (EGC) was followed for a median 7 years to evaluate the causes of death, incidence and patterns of recurrence, and characteristic findings in the recurrent cases. The cumulative 10-year mortality rate (+/- SE) was 22 +/- 3.7%. Seven patients (4.1%) died of operative mortality, 11 (6.4%) died of a recurrence of the gastric cancer and 13 (7.6%) died of unrelated causes. Unrelated causes of death were metachronous primary cancer (n = 6), cardiovascular disease (n = 2), pneumonia (n = 3), sepsis (n = 1), and car accident (n = 1). Four patients died from gastric stump recurrence, three from liver metastases, two from lymph node metastases, and two from peritoneal dissemination. Using Cox multivariate analysis, histologic type had the most significant effect on recurrence. Although influenced by the tumor nature, the EGC prognosis is relatively good. Based on the results of this study, particularly in Western institutions, histologic examination of resection margins and lymphadenectomy should be improved. Moreover, patients must be carefully followed for late recurrence and metachronous cancer.

"Avoidable" mortality may be defined as causes of death whose occurrence is closely related to medical intervention. Areas with particular health care delivery problems can be identified through a geographical comparison of these "avoidable deaths." Mortality data for Valencia from 1982 to 1990 were examined to determine whether or not the availability of medical care resources in the area influenced the occurrence of avoidable deaths. We identified variations in mortality from avoidable causes, grouped according to the differences in levels of urbanization and health care resources, in the 537 municipalities of the Valencian community. (In Spain, the municipality is the lowest administrative division.) Linear regression analysis was performed to predict or estimate this relationship. Only in a small number of avoidable causes did the mortality trend for males differ significantly from 0 (p < 0.005) in relation to different levels of urbanization and health care resources. A direct association between these two variables was observed in males with regards to pneumonia, tuberculosis, chronic rheumatic heart disease, and bacterial infection. In females, a relationship between "avoidable" mortality rates and the differences in urbanization and health care resources was found in cervical cancer, pneumonia, abdominal hernias, and cholecystitis. Mortality from asthma and cardiovascular disease (in both males and females) declined faster in urbanized, high income areas than in rural areas. The results clearly demonstrate the considerable mortality risk associated with living in urban areas. On the contrary, we found very little correlation between health service access and mortality.

All of the 88 episodes of beta-haemolytic streptococcal bacteremia (2.9% of all bacteremias) in adult patients during the years 1987-94 in a university hospital were reviewed. 38 bacteremias (43%) were caused by group A, 24 (27%) by group B, 3 (4%) by group C, and 23 (26%) by group G beta-haemolytic streptococcal. There was a statistically significant increase in group A and decrease in group C and G bacteremias (p < 0.02) compared to an earlier 8-year period in the same hospital, although the total number of streptococcal bacteremias remained the same. The most common T types of group A streptococcal strains were T11 (26%), T28 (14%), T6 and T1 (11% each), and T12 (8%). Cardiovascular disease, skin lesions, malignancy, and alcohol abuse were the most common underlying conditions. The most usual types of infection were skin (47%) and respiratory tract infections (23%). The overall mortality was 16%. It was highest in group A (24%) and lowest in group C (0%), 38% of patients with pneumonia died. All streptococcal strains were sensitive to penicillin, vancomycin, and cephalosporins. 11% of group A and 12% of all the strains had decreased sensitivity to erythromycin, 14 and 38% to tetracycline, and 0 and 2% to clindamycin, respectively.

Symptoms, physical findings, and laboratory values exhibited by some older patients with acute illnesses may differ from those normally expected in a younger population. This variation in presentation can make it difficult to diagnose pneumonia or myocardial infarction and exacerbations of chronic disease, such as depression. The physician who is aware of why and how diseases can present atypically in older patients can improve outcomes by minimizing diagnostic mistakes and delays in treatment. Five common disease states in which atypical presentations may be seen include infections, cardiovascular disease, the acute abdomen, hyperthyroidism, and depression.

A 65-year-old man with rapidly progressing small cell lung cancer found in the course of renal failure is reported. The patient had a medical history of hypertension, diabetes mellitus, and cardiovascular disease. Hemodialysis was introduced following renal failure, but pneumonia resulted in a transient exacerbation and his complaint of general fatigue did not improve. Examination for the fatigue revealed no apparent abnormalities. Three months later, he died of small cell lung cancer.

The prevalence and risk factors for nosocomial lower respiratory tract infections (LRTI) in Germany were determined as part of a national survey on nosocomial infections. The study included 14,966 patients in 72 representatively selected hospitals with departments of general medicine, surgery, obstetrics, gynecology, and intensive care units (ICU). Surveillance was carried out by four previously validated medical doctors who strictly applied the CDC-criteria for diagnosis of nosocomial infections. The overall prevalence of hospital-acquired LRTI was 0.72% with the highest rate in hospitals with more than 600 beds (1.08%) and among the patients on intensive care units (9.00%). Ventilator-associated pneumonia rates were highest in patients on ICUs (13.27). Polytrauma, impaired consciousness, chronic airway disease, prior surgery, and cardiovascular disease were significantly related to the occurrence of nosocomial LRTI. P. aeruginosa was the predominant organism causing nosocomial LRTI. Nosocomial LRTI remain a problem mainly on ICUs. Patients at risk should be monitored with extra care.
