This elderly male with a long history of alcohol abuse presented with an acute pleural trauma and hemopneumothorax, which may have served as the precipitating medical illness for cecal volvulus. He subsequently developed bacterial peritonitis as a complication of his bowel obstruction. It is probable that his pleural cavity was seeded hematogenously via a bacteremia from his peritonitis, thus accounting for the empyema with species typical of bowel flora. Cecal bascule is a type of cecal volvulus that causes intestinal obstruction. Diagnosis is difficult, but a delay in recognition may result in intestinal ischemia, perforation, sepsis, and even death. Cecal ischemia or gangrene cannot always be determined based on physical examination or laboratory findings. Plain films of the abdomen may be helpful, and barium enema has been advocated by some authors. However, laparotomy is often necessary for definitive diagnosis and therapy. While cecal volvulus has not been reported to occur frequently in the elderly, the relatively common occurrence of anatomic predisposition in addition to the widespread use of respirators and the increasing age and number of medical illnesses of our population make it possible that cecal volvulus will be seen with increasing frequency in the future.

Alcohol abuse is the most common cause of end-stage liver disease in the United States, but many transplant centers are unwilling to accept alcoholic patients because of their supposed potential for recidivism, poor compliance with the required immunosuppression regimen and resulting failure of the allograft. There is also concern that alcohol-induced injury in other organs will preclude a good result. From July 1, 1982, to April 30, 1988, 73 patients received orthotopic liver transplants at the University of Pittsburgh for end-stage alcoholic liver disease. Fifty-two (71%) of these were alive at 25 +/- 9 mo (mean +/- S.D.) after transplantation, when a phone survey of these patients, their wives/husbands, and their physicians was performed to evaluate their subsequent use of alcohol, current medical condition and employment. Data obtained were compared with those for nonalcoholic patients selected as transplant controls. The recidivism rate has been 11.5%, with most patients drinking only socially. Fifty-four percent of the survivors are employed, 21% classify themselves as homemakers and only 11 (21%) are unable to work. Twenty-one patients died after transplantation; the most frequent cause of death was sepsis (43%), and intraoperative death was the next most common cause (28.6%). These data demonstrate that alcoholic patients can be transplanted successfully and achieve good health not significantly different from that of individuals transplanted for other causes. Thus orthotopic liver transplantation is a therapeutic option that should be considered for individuals with end-stage alcoholic liver disease who desire such therapy.

Capnocytophaga canimorsus is a fastidious, slow-growing, gram-negative, rod-shaped bacterium that belongs to the normal oral flora of dogs and cats. Human septicemic infections are associated with a high mortality; most cases occur in immunocompromised patients with a history of dog bite. The fifth case of cat-associated septicemia caused by Capnocytophaga canimorsus is described. The six case reports presented here point out the characteristics reported previously: (a) cats are a source of human infection; (b) alcohol abuse is an important risk factor for the development of septicemic Capnocytophaga canimorsus infection; (c) septicemic infection often manifests with disseminated intravascular consumption coagulopathy or purpura; and (d) some cases of septicemia in humans result from pets that lick skin ulcers.

Sepsis due to Streptococcus pneumoniae has a high mortality. We report a retrospective review of 40 episodes of S pneumonia sepsis in adult patients during a two year period in a general hospital, that represented 11.3% of all sepsis observed in such hospital. Ninety two percent of infections were community acquired and in 95%, the portal of entry was the respiratory tract. Eighty five percent of patients had at least one risk factor such as alcohol abuse, unconsciousness or chronic pulmonary disease. Nine patients had suppurative complications (empyema in 4 cases, spontaneous bacterial peritonitis in 2, septic arthritis in 2 and meningitis in 1 case) and 12 (30%) died. The potential benefit of antipneumococcal vaccine as prevention should be considered in high risk subjects.

Massive pulmonary gangrene is a rare complication of pneumonia, particularly in the postantibiotic era. We report two cases of community-acquired Streptococcus pneumoniae pneumonia in young patients with a background of heavy alcohol abuse, but no other preexisting disease, which failed to respond to appropriate antibiotic therapy and intensive care. In both, there was extensive unilateral involvement, with initial dense consolidation followed by cavitation, but the previously reported classic later radiologic feature of coalescence into a large cavity with free-floating slough was not seen. Owing to ongoing sepsis with the development of multiple organ failure and the obvious failure of appropriate medical therapy, both patients underwent pneumonectomy with a successful outcome. These cases serve to emphasize the role of surgery in the management of massive pulmonary gangrene.

A 40-year-old man with diabetes mellitus, congestive heart failure, alcoholic cirrhosis, and chronic pancreatitis had an exacerbation of pancreatitis due to alcohol abuse. His condition deteriorated rapidly with development of apparent sepsis; cultures were negative. He slowly improved with multiple antibiotic therapy and total parenteral nutrition. Serial imaging of the pancreas revealed edematous pancreatitis that evolved initially into a phlegmon and later into multiple pseudocysts. Intermittent fever prompted computed-tomography-directed percutaneous aspiration of the largest pancreatic fluid collection, yielding purulent material that grew only Candida albicans. Subsequently, disseminated candidiasis developed. Despite therapy with amphotericin B and aggressive supportive care, the patient died from multiple organ system failure.

Capnocytophaga canimorsus, formerly designated Dysgonic fermenter 2 (DF-2) was first described in 1976; it is a commensal bacterium of dogs and cats saliva, which can be transmitted to man by bite (54% of cases), scratch (8.5%), or mere exposure to animals (27%). We present a review of the clinical and microbiological characteristics of the Capnocytophaga canimorsus infections and 12 cases of infection in France. Over 100 cases of human infections have been reported, mainly septicemia in patients with diminished defences, due to splenectomy (33%), alcohol abuse (24%), immunosuppression (5%). However 40% of septicemia occur in patients with no predisposing conditions. Other infections are less frequent: meningitis, endocarditis, arthritis, pleural and localized eye infections. These infections range from mild to fulminating disease, with shock, respiratory distress, disseminated intravascular coagulation. Dermatological lesions (macular or maculopapular rash, purpura) or gangrene are common. This fastidious Gram-negative bacterium grows slowly on chocolate agar or on heart infusion agar with 5% rabbit blood incubated in 5% CO2. In spite of a great susceptibility of bacteria to antibiotics, the mortality is of 30%. Because of the severity of these infections, taking into account this organism in the management of bites is necessary, especially in patients with predisposing factors.

In the period of 1984-1996, 569 patients were treated for acute pancreatitis and 37 of them (6.5%) developed infected pancreatic necrosis (IPN). All these patients were submitted to repeated laparotomies according to Bradley's procedure. The IPN was caused by: bile duct stones--in 11 cases, alcohol abuse-14, ERCP-6, trauma-1, in 6 cases the etiology was cryptogenic. The accuracy of imaging tests was: USG-62%, CT-100%. Sepsis was present in all cases, and multiorgan insufficiency-in 25 patients. Hospital mortality was 30% (11 patients). The most frequent reason of death was multiorgan insufficiency. The actuarial survival was 26 patients (70%).

Necrotizing fasciitis is a rapidly progressing, synergistic bacterial infection of fascia with a reported average mortality of about 40%. Fournier's disease, necrotizing fasciitis of the genital sphere, is also included in this study. Seven patients were studied over a one-year period between May 1991 and October 1992. Most commonly, they were infected by perineal diseases, medical procedures and cutaneous ulcers. The local clinical signs are cellulitis, oedema, blisters, necrosis and crepitus; general septic symptoms may also be present. Associated chronic diseases were present in 4 patients. Three infections were polymicrobial. Control of this potentially lethal soft-tissue infection is based on early clinical diagnosis, timely, wide surgical debridements and appropriate antibiotic treatment. The overall mortality rate was 1 of 7 (14%). Death was due to persistent wound sepsis and systemic septic complications, but mainly to delay in surgical treatment. The presence of chronic debilitating diseases (diabetes, alcohol abuse, renal insufficiency, ...) contribute to increase rate of both local and systemic infection.

Previously we reported that alcohol abuse increases the incidence of the acute respiratory distress syndrome (ARDS) in septic patients, and that chronic ethanol ingestion in rats depletes alveolar epithelial glutathione and increases endotoxin-mediated lung edema. In this study we examined a potential mechanism by which ethanol-induced glutathione depletion could predispose to acute lung injury. We hypothesized that glutathione depletion activates matrix metalloproteinases (MMPs), thereby increasing degradation of the alveolar extracellular matrix (ECM) during sepsis. Ethanol-fed rats (20% vol/vol in water for 6 wk) were given endotoxin (2 mg/kg, intraperitoneally) followed 2 h later by lung isolation and ex vivo perfusion with n-formyl-methionyl-leucyl-phenylalanine (fMLP) (10(-)(7) M). Ethanol ingestion increased (p < 0.05) MMP-9 and MMP-2 activity, as determined by zymography, in the lung tissue and lavage fluid compared with control-fed rats, and increased (p < 0.05) levels of the 7S fragment of type IV collagen in the lung lavage fluid. Ethanol ingestion increased activation, but not production, of the MMP-9 and MMP-2 zymogens. Finally, although concomitant ingestion of N-acetylcysteine had no effect (p > 0.05) on MMP production, it increased (p > 0.05) lung glutathione levels, blocked (p < 0.05) MMP-9 and MMP-2 activation, and decreased (p < 0.05) levels of the 7S fragment of type IV collagen. We conclude that chronic ethanol ingestion, via glutathione depletion, activates MMPs during sepsis, thereby increasing degradation of the alveolar epithelial ECM.
