Lethal nosocomial mucormycosis developed in three previously well individuals while they were receiving intensive care for acute hemorrhagic pancreatitis, for cardiogenic shock, and for a ruptured intra-abdominal aortic aneurysm. In two cases, the condition was first seen as progressive cavitary pneumonia refractory to antibacterial therapy; Mucoraceae was identified in all three patients only at autopsy. Each patient had received large doses of corticosteroids and broad-spectrum antibiotics, and all had suffered from respiratory failure, acute renal failure with acidosis, and severe hyperglycemia in association with total parenteral nutrition. Mucoraceae should be regarded as an additional nosocomial pathogen in the setting of advanced life-support care.

This paper reports three cases of acute pancreatitis that occurred after repair of an abdominal aortic aneurysm. The aneurysms were ruptured in two patients and asymptomatic in one. No patient had biliary disease or history of pancreatitis or alcohol abuse. Two of the patients required operation for drainage and debridement; one died. The etiology and diagnosis are discussed.

Occurring rarely after aortic surgery, post-operative pancreatitis is often complicated and carries a high mortality rate. We have reported a case of pancreatic pseudocyst involving a polytef aortic prosthesis used to repair a ruptured abdominal aortic aneurysm. The pseudocyst was treated successfully by repeated percutaneous aspiration, and removal of the aortic prosthesis was not required. Although less successful than operative drainage, percutaneous approaches to pancreatic pseudocysts are an important option for patients who are poor surgical candidates.

Emergency surgery is the only effective treatment of ruptured abdominal aortic aneurysms, even though morbidity and mortality rates remain high. We have studied the feasibility of left retroperitoneal aortic exposure in these cases in an effort to reduce postoperative complications. Over a 33 month period, 29 patients underwent emergency surgery for either a ruptured or symptomatic infrarenal abdominal aortic aneurysm. Of 13 patients with ruptured aneurysms, 4 underwent repair through a midline transperitoneal approach (3 deaths) whereas the remaining 9 were repaired through the retroperitoneal exposure (1 death). Supraceliac aortic clamping through the same incision prior to aneurysm exposure maintained hemodynamic integrity. The remaining 16 patients with symptomatic aneurysms were all treated through the retroperitoneal exposure (3 deaths). In the retroperitoneal groups, the cause of death was cardiac in two patients, hypertensive stroke in one, and necrotizing pancreatitis in one. Morbidity consisted of prolonged intubation, respiratory distress syndrome, and thrombophlebitis in one patient each and acute tubular necrosis in two patients. We believe that the left retroperitoneal approach is a useful option in the emergent treatment of abdominal aortic aneurysms.

An early event in the evolution of acute respiratory failure (ARF) is thought to be the activation of platelets, their pulmonary entrapment and subsequent release of the smooth muscle constrictor serotonin (5HT). This study tests the thesis that inhibition of 5HT will improve lung function. The etiology of ARF in the 18 study patients was sepsis (N = 10), aspiration (N = 3), pancreatitis (N = 1), embolism (N = 2), and abdominal aortic aneurysm surgery (N = 2). Patients were divided into two groups determined by whether their period of endotracheal intubation was less than or equal to 4 days (early ARF, N = 12) or greater than 4 days (late ARF, N = 6). Transpulmonary platelet counts in the early group showed entrapment of 26,300 +/- 5900 platelets/mm3 in contrast to the late group where there was no entrapment (p less than 0.05). The platelet 5HT levels in the early group were 55 +/- 5 ng/10(9) platelets, values lower than 95 +/- 15 ng/10(9) platelets in the late ARF group (p less than 0.05), and 290 +/- 70 ng/10(9) platelets in normals. The selective 5HT receptor antagonist, ketanserin was given as an intravenous bolus over 3 minutes in a dose of 0.1 mg/kg, followed by a 30-minute infusion of 0.08 mg/kg. During this period mean arterial pressure (MAP) fell from 87 +/- 5 to 74 +/- 6 mmHg (mean +/- SEM) (p less than 0.05). One and one-half hours following the start of therapy, MAP returned to baseline. At this time, patients with early ARF showed decreases in: physiologic shunt (Qs/QT) from 26 +/- 3 to 19 +/- 3 (p less than 0.05); peak inspiratory pressure from 35 +/- 2 to 32 +/- 2 cmH2O (p less than 0.05) and in mean pulmonary arterial pressure from 32 +/- 2 to 29 +/- 1 mmHg (p less than 0.05). At 4 hours all changes returned to baseline levels. In early ARF ketanserin did not alter pretreatment values of: pulmonary arterial wedge pressure, 17 +/- 3 mmHg; cardiac index, 2.8 +/- 0.3 L/min X m2; platelet count, 219,000 +/- 45,000/mm3; platelet 5HT, 55 +/- 5 ng/10(9) platelets; plasma 5HT, 142 +/- 21 ng/ml; plasma thromboxane B2, 190 +/- 30 pg/ml; or plasma 6-keto-PGF1 alpha, 40 +/- 10 pg/ml. Ketanserin infusion in patients with late ARF yielded no benefit. In both ARF groups the decreases in QS/QT were inversely related to the duration of intubation (r = 0.70; p less than 0.05).(ABSTRACT TRUNCATED AT 400 WORDS)

Back pain affects millions of people. It affects 80% of the population and up to 52% at any given time. Back pain is not limited to sedentary individuals; it has significant effects on athletes as well. Depending upon the sport, incidence rates of back pain occur in athletes from 1.1% to as high as 30%. Athletes differ from the non-athletic population in that their incentives to return to activity are considerably different than non-athletes. The reasons may vary from the will to win through to significant financial considerations. Although reasons for recovery are different, the physiology and mechanics of repair of injured soft tissue in the athlete is the same as for the non-athlete. Proper management of the athlete requires ruling out emergent causes of back pain such as tumour, infection, acute fracture, progressive neurological deficit, visceral sources (e.g. pancreatitis, abdominal aortic aneurysm), and rheumatoid variants. Once a good history and physical is performed, a simple classification system can be utilised to manage the athlete presenting with back pain. This system can be expressed as: (a) regional back pain; (b) radicular leg pain; (c) radicular leg pain with progressive neurological deficit; and (d) cauda equina syndrome. Each of these categories needs to be managed in a specific manner and can provide the healthcare professional with simple, straightforward guidelines for handling the athlete with lower back pain. The key is to return the athlete to the field of play in a safe and timely manner.

Acute pancreatitis (AP) after aortic surgery has rarely been reported. A retrospective review of all abdominal and thoracoabdominal aortic operations complicated with AP from January 1982 to March 1992 was performed to study the presentation and outcome of this infrequently recognized complication. Thirteen cases of AP were found among 1965 abdominal aortic operations (0.7% incidence). The distribution of the original aortic operations was as follows: eight elective abdominal aortic aneurysm repairs, two aortoiliac grafts for aortoiliac occlusive disease, and three aortorenal bypasses. Two cases of pancreatitis complicated 170 thoracoabdominal aortic operations (1.2% incidence). Ten patients had mild pancreatitis, nine were discharged without any pancreatic complications after receiving supportive treatment. Five patients with severe AP died of multisystem organ failure despite aggressive surgical treatment; 4 had infected necrosis. The overall mortality was 40 per cent; severe AP resulted in a 100 per cent mortality. The diagnosis of severe AP was usually made in the second postoperative week, significantly later (P < 0.01) than for patients with mild disease. Typically, patients with mild AP presented with hyperamylasemia at a median of 5 postoperative days, and severe AP was found at reoperation or autopsy after a period of unexplained sepsis. Five patients with mild AP were found to have biliary tract stones, with one requiring endoscopic stone extraction. In conclusion, pancreatitis is an uncommon, although perhaps underreported complication. Underreporting may be due to a lack of hyperamylasemia when severe pancreatitis is diagnosed. The severe form is diagnosed late in patients with postoperative sepsis, associated with infected necrosis, and lethal. The complication may be reduced by incidental cholecystectomy for cholelithiasis.

Three patients, two men aged 70 and 73 years, respectively, who underwent surgery due to an abdominal aortic aneurysm, and a woman aged 75 years, who was operated on due to acute arterial embolic occlusion of both legs, developed abdominal complaints post-operatively. These were found to be caused by necrotising pancreatitis. The accompanying fluid accumulation was drained percutaneously. Two patients recovered; the 73-year-old man died suddenly, possibly as a result of burst aortic sutures. In patients with a serious condition, necrotising pancreatitis should be considered in the case of a generalised inflammatory reaction and abdominal symptoms. Percutaneous drainage of infected necrotic tissue can sometimes improve the patient's condition, making surgery possible at a later stage.

The abdominal compartment syndrome (ACS) is a clinical entity that develops after sustained and uncontrolled intra-abdominal hypertension. ACS has been demonstrated to affect multiple organ systems including the cardiovascular, respiratory, gastrointestinal, genitourinary, and neurologic systems. To date most descriptions of ACS are found in the trauma literature, but the development of ACS in the general surgical population is being increasingly observed. In this study the development of ACS in a nontrauma surgical population is described and examined. The records of 18 surgical intensive care unit patients with documented ACS were reviewed retrospectively. Data acquired included demographics, urine output in mL/hour, cardiac index in L/m2/min: systemic vascular resistance index in mm Hg/L/m2/min: and pulmonary artery occlusion pressure, peak inspiratory pressure, partial pressure of oxygen in arterial blood, pH, partial pressure of carbon dioxide, and intra-abdominal pressure (all in mm Hg). When they were available values were obtained before and after decompression. Data are presented as mean +/- standard deviation and are analyzed by Student's t-test; significance was accepted to correspond to a P value <0.05. Nineteen episodes of ACS were identified in 18 patients. The average age was 69.2 years, and the observed mortality of the group was 61.1 per cent (11 of 18). Diagnoses included abdominal aortic aneurysm (eight), postoperative laparotomy (six), pancreatitis (three), and cerebral aneurysm (one). Of the parameters examined urine output, peak inspiratory pressure, and cardiac index demonstrated a significant change before and after decompression. The average intra-abdominal pressure was 43.4 mm Hg. Five of 18 patients (two with abdominal aortic aneurysm, two with postoperative laparotomy, and one with pancreatitis) were found to have necrotic bowel on decompressive laparotomy. The development of ACS is described in a surgical intensive care unit. ACS is the end result of uncontrolled intra-abdominal hypertension and results in systemic derangements. Surgical decompression of ACS significantly reduces peak inspiratory pressure while increasing urine output and cardiac index. The observed association between ACS and ischemic bowel may result from decreased mucosal perfusion as a direct result of abdominal hypertension. In our patient population ACS resulted in a 61.1 per cent mortality.
