Since 1961, 200 human isolates of Capnocytophaga canimorsus--a gram-negative bacterium--have been sent to CDC for identification. Infections with this organism may result in a spectrum of manifestations ranging from self-limiting cellulitis to fatal septicemia; most fatal infections have occurred in persons with a history of asplenia, alcoholism, or hematologic malignancy. In most (77%) cases, infection is preceded by a bite or other exposure to dogs. This report summarizes the investigation by the New Mexico Health and Environment departments and CDC of a fatal case of C. canimorsus infection in a resident of New Mexico. This case was initially misdiagnosed as human plague.

Today Fournier's gangrene ranks among necrotizing fasciitis. Most of the cases reveal the origin of the disease (proctogenic, urologic, gynecologic). Untreated, the polybacterial synergistic infection will overwhelmingly spread along anatomically defined fascias of the pelvic floor. Thus the lethality rate is high, especially in patients with risk factors i.e. diabetes, alcoholism, arterial occlusive disease, chronic consumptive disorders and obesity. Only by instant and radical surgical excision of the total gangrenous tissue the spreading of the disease and the developing of sepsis can be stopped together with calculated antibiotic therapy and intensive care. Mutilating operations (i.e. penectomy, orchiectomy) are seldom necessary; thus plastic reconstructions will show good results both in function and cosmetic. Based on the experience with 6 patients, a pathogenic concept, concerning both diagnosis and therapy, is presented: after radical emergency surgery in the first risky stage, an elective approach can safely be performed in a second stage for the repair of functional lesions.

Alcohol, consumed as 36% of the caloric intake for 8-10 wk, causes a potentiation of cardiac dysfunction induced by a second insult, sepsis. Because chronic alcoholism may attenuate the responsiveness of the myocardium to catecholamine stimulation, and because catecholamine support seems to be essential for the myocardium to generate an adequate cardiac output in sepsis, we hypothesized that the heart from the alcoholic septic rat would show a compromised inotropic responsiveness to catecholamines compared with the heart from the nonalcoholic septic rat. To test this hypothesis, rats were fed an ethanol-containing or control liquid diet for 8-10 wk and were then made septic with live Escherichia coli (10(10) E. coli) through a dorsal subcutaneous catheter. The next day, hearts were removed and perfused at a constant hydrostatic pressure, and a compliant balloon was placed in the left ventricule for measurement of pressure (LVP). Hearts were paced at 350-360 beats/min. Hearts were allowed to stabilize for 15 min, and then the response to a submaximal dose of isoproterenol (Iso) was measured. Hearts recovered for 30 min, at which time the response to a maximum dose of Iso was recorded. Basal (pre-Iso) LVP was lower in the control septic and alcoholic septic groups than in the control and alcohol groups. However, the maximum increase in LVP in response to Iso was greater in the two septic groups than in the two nonseptic groups. The peak LVP in response to Iso was similar in the control, septic, and alcoholic septic groups, and was significantly greater than in the alcohol group.(ABSTRACT TRUNCATED AT 250 WORDS)

The etiology, microbiologic findings, and management of 82 episodes of empyema treated by our unit over a period of 6 years were analyzed. Average patient age was 54 years. Eighty-two percent had underlying disease such as alcoholism (29 percent), malignancy (23 percent), and diabetes mellitus (20 percent). Sixty (73 percent) had an empyema develop secondary to a bronchopulmonary infection. Other etiologies were as follows: infradiaphragmatic sepsis, five cases; iatrogenic, ten cases; and idiopathic, seven cases. Cultures were positive in 76 cases and negative in the remaining 6 (2 positive Gram stains, 1 positive under bacilloscopy, and 3 were sterile). Anaerobes were isolated from 25 and aerobes from 47 of the positive cultures. A single bacteria was isolated from 43 and multiple organisms (average: 2.63/case) grew on the remaining 33 positive cultures. Length of hospitalization averaged 37 days. Seven patients received antibiotics only, thoracentesis was performed on three, intercostal chest tube drainage was required in 72, and more aggressive surgery was performed on 12 patients (7 with fibrothorax and 5 with pneumonectomy). Streptokinase was instilled into the pleural space of eight patients with good results. Pleural drainage superinfection occurred at a rate of 8.5 percent. Nine patients died; the remaining recovered. Only three deaths came about as a direct result of the empyema.

A 12-year review identified 21 patients with nontyphoidal, nonparatyphoidal salmonella septicemia. Eight of the patients had no predisposing factors. Factors identified included malignancy in five, recent surgery in four, alcoholism with aspiration pneumonia in two, chronic lung disease in two, diabetes in two, systemic lupus erythematosus in one and burns in one. Ten patients presented with gastroenteritis, two with localized abscesses, two with aspiration pneumonia and the remainder with nonspecific septicemia. Three patients died of underlying diseases and three died shortly after the septicemia of related causes. Six cases were nosocomial infection and were not related to hospital outbreaks. Salmonella septicemia with these serotypes is uncommon (1 per 14,000 admissions, 1 per 4000 blood cultures) and can occur in patients without diminished host resistance.

A 69-year-old alcoholic man with pneumonia and sepsis due to Aeromonas hydrophila is presented. He died of suffocation by a copious amount of hemoptysis six hours after his first symptoms of abdominal pain, diarrhea and dyspnea. Aeromonas hydrophila was isolated from blood and bronchial secretion. A fulminant form of pneumonia could develop in patients with predisposing underlying conditions such as alcoholism with chronic hepatitis and diabetes mellitus. Aeromonas hydrophila pneumonia may be characterized by hemoptysis and rapid clinical deterioration with a high mortality rate.

Thirty-nine Danish cases of Capnocytophaga canimorsus septicemia were reviewed to determine the clinical course of this infection. The cases of septicemia were related to recent dog bites or other close contact with dogs. The period from the bite to the onset of symptoms ranged from 1 to 8 days. The mean age of the patients was 59.1 years (range, 28-83 years). Underlying conditions included previous splenectomy and alcoholism. Thirteen patients had previously been in good health. Common initial symptoms were fever, malaise, myalgia, vomiting, diarrhea, abdominal pain, dyspnea, confusion, headache and skin manifestations. Disseminated intravascular coagulation developed in 14 patients, meningitis in 5, and endocarditis in 1. Twelve of the patients died. All patients except two were treated with penicillin or ampicillin. Five patients had received antibiotics prior to admission. Attention should be drawn to C. canimorsus septicemia in cases of febrile illness following dog bites or contact with dogs, as well as those involving previously healthy persons. The incidence of this condition in Denmark is estimated to be 0.5 case per 1 million people per year.

In the last few years, Computed Tomography (CT) has emerged as the most sensitive and reliable imaging technique to diagnose acute pancreatitis (AP). Besides assessing the extent of damage to the pancreas and to periglandular tissue. CT can recognize the major early and late complications of the disease promptly and with extreme accuracy. We investigated the diagnostic capabilities of CT in controlling AP development and tried to assess the role of interventional radiology as a therapeutic support after or instead of surgery in treating the necrotic forms of pancreatitis complicated by sepsis. From 1989 to 1995, acute pancreatitis mostly due to biliary tract disease and alcoholism was diagnosed in 228 patients. Necrotic processes were identified in 105 of them since disease onset; septic complications developed in 57 patients. Surgery was performed in 42 patients, but the result was poor in 11 of them (30%) and CT showed the persistence of some infectious pancreatic exudate which had been drained insufficiently. Since sepsis persisted in these patients, the exudate was aspirated percutaneously after positioning appropriate drainage means guided by abdominal CT. Sepsis resolved completely in 10 patients, while one required subsequent surgery. Percutaneous drainage catheters were positioned in 15 patients as the treatment of choice, under CT and US guidance. Sepsis resolved in 7 cases only (45%), while 3 of the extant patients died and 5 needed surgery. The results of our experience demonstrate the effectiveness of percutaneous drainage under CT guidance. However, this technique should be used after and as a support to surgery, the latter remaining the treatment of choice for infectious necrotic AP. Thus, in our experience, the use of percutaneous aspiration instead of surgery proved to be a less effective tool in curing this condition and its use should therefore be limited to high-risk surgical patients.

A 66-year-old man with a history of chronic alcoholism presented with Kussmaul respirations following several days of fasting accompanied by vomiting, in the presence of continued ethanol intake. He was subsequently found to have a serum glucose level of <20 mg/dL and an anion gap of 36. Despite his profound hypoglycemia, he was fully alert with no obvious neurological deficits. He recovered without incident with intravenous saline, dextrose, thiamine, and antibiotics for a bacteremic pneumonia. He had no evidence of hypoxemia, hypotension, or other features of sepsis. Alcoholic ketoacidosis in the setting of hypoglycemia is discussed. If the serum glucose level is less than the anion gap, the diagnosis of alcoholic ketoacidosis should be considered.

Chronic alcohol abuse increases the incidence and mortality of the acute respiratory distress syndrome (ARDS) in septic patients. To examine a potential mechanism, we hypothesized that ethanol ingestion predisposes to sepsis-mediated acute lung injury by decreasing alveolar type II cell glutathione homeostasis and function. Lungs isolated from rats fed ethanol (20% in water for >/= 3 wk), compared with lungs from control-fed rats, had greater (P < 0. 05) edematous injury (reflected by nonhydrostatic weight gain) after endotoxin (2 mg/kg intraperitoneally) and subsequent perfusion ex vivo with n-formylmethionylleucylphenylalanine (fMLP, 10(-7) M). Ethanol ingestion decreased (P < 0.05) glutathione levels in the plasma, lung tissue, and lung lavage fluid, and increased (P < 0.05) oxidized glutathione levels in the lung lavage fluid. Furthermore, ethanol ingestion decreased type II cell glutathione content by 95% (P < 0.05), decreased (P < 0.05) type II cell surfactant synthesis and secretion, and decreased (P < 0.05) type II cell viability, in vitro. Finally, treatment with the glutathione precursors S-adenosyl-L-methionine and N-acetylcysteine in the final week of ethanol ingestion significantly reduced lung edema during perfusion ex vivo. We conclude that ethanol ingestion in rats alters alveolar type II cell glutathione levels and function, thereby predisposing the lung to acute edematous injury after endotoxemia. We speculate that chronic alcohol abuse in humans predisposes to ARDS through similar mechanisms.
