Over the past 50 years, survival has improved in patients with systemic lupus erythematosus and associated nephritis. Yet, there are few long-term outcome studies in patients with well-defined nephropathy. We examinbed the outcome of 439 patients with lupus nephritis who were seen at the Mayo Clinic between 1964 and 1986 in whom renal biopsies were assessed using the World Health Organization (WHO) classification. There were 341 women and 98 men (mean ± s.d., age 33.5 ± 14 years); 200 (46%) patients were hypertensive and 249 (57%) had impaired renal function at renal biopsy. All WHO morphologic classes were represented and 339 (77%) patients had class III, IV and V (the more severe forms of nephritis). Follow-up averaged 10.2 years per patient. At last contact, 286 (65%) patients were alive and 153 (35%) were dead. Overall patient survival was 80%, 69% and 53% at 5, 10 and 20 years after biopsy that was significantly worse than expected survival (P < 0.001). Ten-year cumulative patient survival improved comparing earlier to more recent time spans: 64% in 231 patients seen during 1964-75; 76% in 2089 patients studied during 1976-86 (P = 0.03). Survival free of renal failure was 83%, 74% and 64% at 5, 10 and 20 years, and survival was unfavorably influenced by progressive WHO class, hypertension, impaired renal function, nephrotic range proteinuria, hypoalbuminemia and anemia. Multivariate analysis found impaired renal function, increased urine protein, anemia and younger age to be independent predictors of renal failure. WHO class was not a significant predictor when adjusted for these four factors. Cardiovascular events accounted for 48% of the known deaths and were equally distributed across all WHO classes, followed by infections, renal failure, malignancy, respiratory failure and gastrointestinal bleeding. Severe nephritis, nephrotic syndrome, hypertension and anemia remain strong predictors of a poor renal outcome. Prospective randomized studies stratifying for these factors are needed to find optimal immunosuppressive regimens to improve renal survival.

Many observations suggest that certain nonprogressive neurologic disorders are the sequelae of intracerebral or intracranial hemorrhage or both, but the role played by these factors as well as hypoxia is difficult to ascertain even at autopsy. As a rule, intracranial bleeding in infants (neonates excluded) and children is secondary to trauma. Some of these children are left with some neurologic deficit, depending upon the site and severity of the breeding and the promptness of therapy.

What disease states are occasionally associ ated with hypogarathyraidisna? Is there any explanation for the association of moniliasis or steatorrhea in the syndrome re ported ? Is there a familial incidence of the syndrome of hypoparathyroidism, Addison's disease and moniliasis?

Medical and surgical emergencies occasionally present as ruptured abdominal aortic aneurysms (RAAA). To assess benefits of laparotomies and adverse effects of unnecessary operations, the authors reviewed their experience. Thirteen patients, 9 women, 4 men (mean age: 72 years, range: 41-85) underwent emergency laparotomy between 1988 and 1996 for presumed RAAA and were found to have other surgical or medical emergencies. All the patients presented with hypotension, 12 had abdominal or back pain, four had pulsatile abdominal mass. Rupture was not excluded by computed tomography scan in three or by ultrasonography in two patients. Laparotomy disclosed intact abdominal aorta in all, but seven patients had abdominal aortic aneurysm. Of five surgical emergencies, laparotomy was indicated in four: three for ruptured visceral artery aneurysms, one for perforated duodenal ulcer. The fifth patient required thoracotomy for ruptured thoracic aneurysm. Four of eight medical emergencies were myocardial infarctions. One iatro genic complication required reoperation for bleeding. Mean hospital stay was 18 days; mean hospital charges were $40,771. Seven (54%) early deaths occurred; none were caused directly by the operation. Laparotomy was indicated in one third of deceptive emergencies that present as RAAA. Although mortality, morbidity, and costs were high, iatrogenic surgical complica tions were rare and deaths were not caused by unnecessary operations.
