The risk of hernia with large exchange volumes.

Large exchange volumes of 2.5 and 3 L are frequently necessary to improve clearances to the level suggested by the DOQI guidelines. However, abdominal wall hernias are a well known complication of peritoneal dialysis (PD) related to increased abdominal pressure, and might increase with higher exchange volumes. We studied the effect of using higher exchange volumes in PD patients on the incidence of hernia formation. Seventy-nine (12%) of 656 PD patients over a 15-year span developed abdominal wall hernias. Eleven percent of patients using 2 L or smaller volumes, 15% of patients using more than 2 L but less than 3 L, and 13% of patients using 3 L developed hernias (not significantly different). Five percent of patients on cyclers for their entire PD experience (3 of 63 patients) developed one or more hernias, compared to 13% of patients on continuous ambulatory peritoneal dialysis for at least part of their experience (P = 0.06). The use of larger volumes increased dramatically over time; only 11% of patients used more than 2-L exchange volumes during the years 1982 through 1986, compared to 73% in the period from 1992 to 1997. We conclude that increased volumes in PD patients do not lead to an increased risk of hernia formation. Exchange volumes can be increased as needed to improve clearances.

Care of acute myocardial infarction by noninvasive and invasive cardiologists: procedure use, cost and outcome.

OBJECTIVES: This study sought to determine how noninvasive and invasive cardiologists may differ in the hospital care of patients with acute myocardial infarction. BACKGROUND: Scant information exists regarding the effect of noninvasive and invasive cardiology subspecialization on invasive cardiac procedural use, cost and outcome in the care of patients with acute myocardial infarction. METHODS: This study analyzed a prospective cohort of 292 patients admitted to an urban tertiary care hospital from the emergency room under the care of noninvasive or invasive cardiologists. Clinical characteristics; hospital course, including management, utilization of diagnostic coronary angiography and percutaneous transluminal coronary angioplasty; direct hospital costs; length of hospital stay; and post-hospital discharge follow-up data were collected by a prospective data base instrument. RESULTS: Despite similar clinical characteristics, extent and severity of coronary artery disease and utilization of diagnostic coronary angiography in the two groups of patients, those under the care of an invasive cardiologist were significantly more likely to undergo coronary angioplasty than those under the care of a noninvasive cardiologist. The direct hospital costs and length of stay of the noninvasive and invasive group patients who underwent coronary angioplasty were similar, although overall the direct hospital costs and length of stay were higher for the invasive than for the noninvasive group patients. CONCLUSIONS: Noninvasive and invasive cardiologists differ in their rate of utilization of coronary angioplasty in similar patients with acute myocardial infarction.

Plasma cell granuloma: maxillary sinuses.

Inflammatory pseudotumours or plasma cell granulomas are space-occupying, rounded masses appearing in various locations usually as an aftermath of recurrent infections. Recurrent pain and mass have been the most common presentations (Durst et al., 1977). These have been confused with tumours but radical surgical treatment is unnecessary, in the absence of life-threatening complications. The prognosis is excellent after excision. The nature and pathogenesis of the inflammatory pseudotumours, their presentation as fever and anaemia in some cases, are unknown. This report is probably the first case of a plasma cell granuloma involving the maxillary sinus causing focal erosion of the orbital wall, simulating a malignant tumour clinically.
