- BACKGROUND: The aim of the present study was to report the risk of death in a national cohort of patients with aPC (adrenal PC) and their risk of developing a second tumour. METHODS: Using the National Cancer Registry, 481 patients (222 men and 259 women) with aPC in Sweden (1958-1997) were identified. Autopsy-based diagnoses were excluded. As control group the entire Swedish population was used and the risk of death in patients after diagnosis of aPC was compared with the normal risk taking age, sex and calendar year into account. The risk for a second tumour disease after diagnosis of aPC was also calculated. RESULTS: Patients with aPC had an increased tumour-related mortality after diagnosis of aPC. For both men and women this mortality was four times higher than for controls. Liver/biliary tract and CNS tumours in men; and malignant melanoma and uterine cervical cancer in women were significantly over-represented in the cohort of patients with aPC. CONCLUSION: Patients with aPC run an increased risk of developing additional cancers. Surveillance strategies may thus be necessary for these patients.

- AIM: To assess the possible protective effect of exclusive breastfeeding against first-time febrile urinary tract infection (UTI) in children. METHODS: Two children's hospitals and local child health centres in the Goteborg area, Sweden, participated in a prospective case-control study. In total, 200 consecutive cases (89M, 111F), aged 0-6y, presenting with first-time febrile UTI were enrolled. The mean +/- SD age was 0.98 +/- 1.15 y. As control subjects, 336 children (147M, 189F) were recruited from the child health centre of the case, matched for age and gender and included consecutively for each case during the first days after diagnosis. The duration of exclusive breastfeeding was obtained from the case and controls by a standardized procedure. RESULTS: Ongoing exclusive breastfeeding gave a significantly lower risk of infection. A longer duration of breastfeeding gave a lower risk of infection after weaning, indicating a long-term mechanism. The protective role of breastfeeding was strongest directly after birth, then decreased until 7 mo of age, after which age no effect was demonstrated. CONCLUSION: A protective role of breastfeeding against UTI was demonstrated. The study provides statistical support to the view that breast milk is a part of the natural defence against UTI.

- OBJECTIVE: There are gender differences in clinical presentation, treatment and outcome of patients with coronary artery disease. We investigated whether there is also a gender difference in terms of mortality risk on the waiting list in patients accepted for coronary artery bypass grafting (CABG). METHODS: All our patients accepted for elective CABG 1995-1999 (1303 women and 4561 men) were included. Prospectively registered preoperative characteristics and mortality were compared between men and women. Hazard functions for death on the waiting list were calculated using Poisson regression. RESULTS: At acceptance, women were older (68+/-9 vs 65+/-9 years, P<0.001), had a higher Cleveland risk score (2.4+/-1.8 vs 1.8+/-1.8, P<0.001) and a better left ventricular ejection fraction (60+/-14 vs 57+/-14%, P<0.001). More women had unstable angina pectoris (33 vs 20%, P<0.001), diabetes mellitus (23 vs 17%, P<0.001), chronic obstructive pulmonary disease (8 vs 5%, P<0.001), hypertension (47 vs 37%, P<0.001) and planned concomitant aortic valve surgery (13 vs 4%, P<0.001) while more men had three vessel disease (70 vs 66%, P=0.001). Median waiting time (55 vs 54 days, P=0.19) and unadjusted mortality (1.4 vs 1.0%, P=0.25) on the waiting list did not differ significantly between men and women but in a multivariate hazard analysis, female gender was associated with a lower risk than men of death on the waiting list (risk ratio 0.42, 95% confidence interval 0.19-0.93, P=0.032). CONCLUSIONS: Women have a lower risk of death on the waiting list for CABG, in spite of more advanced age, more co-morbidity, and a higher percentage of unstable angina pectoris.

- BACKGROUND: Insufficient capacity for coronary artery bypass grafting results in waiting times before operation, prioritization of patients and, ultimately, death on the waiting list. We aimed to calculate waiting list mortality and to identify risk factors for death on the waiting list. METHODS: The study included 5,864 consecutive patients accepted for elective coronary artery bypass grafting (78% male; mean age, 66 +/- 9 years). The patients were categorized at acceptance into three priority groups: imperative (39%), urgent (36%), or routine (25%). Waiting list mortality was calculated and compared between groups, and risk factors were identified by Poisson regression. RESULTS: Median waiting time for the whole population was 55 days. Seventy-seven patients (1.3%) died, corresponding to a mortality rate of 5.8 deaths per 100 patient-years. The mortality rate per 100 patient-years was highest for those in the imperative group, 15.1 deaths, compared with 5.3 deaths in the urgent group and 3.2 in the routine group (p < 0.001). Independent risk factors were male sex (p = 0.032), Cleveland Clinic risk score (p = 0.005), impaired left ventricular ejection fraction (p = 0.007), unstable angina pectoris (p = 0.001), concomitant aortic valve disease (p = 0.002), priority group (p < 0.001), and time after acceptance (p = 0.019). The mortality risk increased with time after acceptance by 11% a month. CONCLUSIONS: Long waiting lists for coronary artery bypass grafting are associated with considerable mortality. The risk of death increases significantly with waiting time. Sex, unstable angina, perioperative risk, impaired left ventricular function, and concomitant aortic valve disease are independent risk factors and should be considered at triage.

- A retrospective comparison was performed between 1411 hypopituitary adults without GH replacement [mean age, 56.9 (sd 18.6) yr] and the normal population in terms of fatal and nonfatal morbidity. A similar prospective comparison was then made in 289 hypopituitary patients on long-term GH replacement [mean age, 47.6 (sd 14.8) yr; mean duration of GH treatment, 60 months].In the 1411 hypopituitary patients without GH replacement, overall mortality (P < 0.001), and the rates of myocardial infarctions (P < 0.01), cerebrovascular events (P < 0.001), and malignancies (P < 0.001) were increased compared with the normal population. Colorectal cancer was the most common malignancy in this cohort (P < 0.001 vs. the background population). In the 289 hypopituitary patients on GH replacement, overall mortality and the rate of malignancies were similar to the normal population. In the hypopituitary adults on GH therapy, the rate of myocardial infarctions was lower than that in the background population (P < 0.05), and there was a tendency toward an increased rate of cerebrovascular events.In conclusion, overall mortality and the rate of myocardial infarctions were increased in hypopituitary patients without GH replacement. An increased rate of malignancies was observed in the hypopituitary adults without GH therapy, with a predominance of colorectal cancer. GH replacement appeared to provide protection from myocardial infarctions. The rate of cerebrovascular events tended to be increased also in hypopituitary adults on GH therapy.
