Acute centrolobular necrosis, cancers related to occupational chemical exposures, and infectious hepatitis are widely recognized, but other occupational and environmental diseases of the gastrointestinal tract are underemphasized by comparison. This review explores the associations between workplace exposures and steatosis, increased liver microsomal activity, cholestatic liver injury, portal fibrosis and hepatic sclerosis, granulomatous liver disease, porphyria cutanea tarda, peptic ulcer disease, pancreatitis, gastroenteritis, celiac disease, and pneumatosis cystoides intestinalis.

Vibrio vulnificus is an extremely invasive gram-negative bacillus that causes bacteremia and shock. It should be suspected in any patient who is immunocompromised or has liver disease or hemochromatosis. Reduced gastric acidity may also increase the risk of infection if a patient presents with a history of ingesting raw shellfish (especially oysters) or trauma in brackish waters and skin lesions. Patients most commonly present with one of three clinical syndromes: primary septicemia, wound infection, or gastroenteritis. Treatment includes aggressive wound debridement, antibiotic therapy, and supportive care. Rapidly diagnosing and promptly initiating therapy are critical because V vulnificus infection is rapidly progressive and mortality approaches 100% if septic shock occurs.

Non 01 V.cholerae is known to cause gastroenteritis and extra intestinal manifestations, including septicemia. We report here our isolation of non 01 V.cholerae from various clinical specimens. Although most of the isolates are from faeces samples from patients with diarrhoea, we have three isolates from blood culture in patients with underlying liver disease. The highest incidence occurred in 1982-1983 and 1987 and 1988.

Halophilic vibrios are gram-negative curved bacilli that requires high concentrations of salt for survival. They are usually found in marine environments and have a worldwide distribution. Infections caused by these organisms are usually associated with ingestion of raw shell fish or exposure of wounds to sea water. The clinical presentation and severity of this infections is wide ranging. The most common presentation is self-limiting gastroenteritis, but soft tissue infections and septicemia do occur and their morbidity and mortality is high specially in patients with liver disease. Early detection and initiation of treatment with tetracycline is of vital importance in soft tissue infections and septicemia since the progression of the infection may be extremely fast.

Seventy-seven patients with locally advanced, nonresectable, biopsy-proven adenocarcinoma of the pancreas were treated by palliative bypass surgery followed by intensive neutron beam irradiation of the primary tumor site. Three dose levels, under 20, 21 to 23, and 24 to 25 Gy, were studied with the use of a treatment plan that included all known disease within a limited target volume, generally under 2 l. Symptomatic palliation was achieved in the majority of patients. The median survival time was 6 months. One patient remained alive and well without evidence of tumor 5 years after irradiation. Two were free of tumor at autopsy (one had died of intercurrent disease and one of radiation-related complications). A common cause of death was metastatic dissemination. Complication rates were dose-dependent; life-threatening complications did not exceed 12% with doses of less than 23 Gy. Autopsies from 19 patients were reviewed. In all, the pancreatic tumor site showed extensive reactive fibrosis. Local control was achieved in two patients, but most had both residual tumor in the pancreas and metastases. Six patients had centrolobular veno-occlusive liver disease. These patients had all received the higher (22-24 Gy) neutron doses. Six patients had hemorrhagic radiation gastroenteritis. Mild skin atrophy and bone marrow hypoplasia were seen in the irradiated volumes. The kidneys and spinal cord showed no radiation effects. The authors conclude that neutron irradiation can provide a good local response with marked regression and fibrosis of the tumor. This response, coupled with many deaths due to metastases, suggests that combined treatment with neutrons and chemotherapy would be worth exploring.

Noncholera vibrio species can cause necrotizing soft tissue infections and cellulitis in addition to gastroenteritis. Cellulitis and necrotizing soft tissue infections frequently occur in people with liver disease or in people who are in some way a compromised host. We studied the effect of Vibrio vulnificus on the mortality of mice treated with carbon tetrachloride, an agent that causes liver damage, Desferal, an iron-chelating agent, or iron. The LD50 of V. vulnificus is approximately 2.5 X 10(6) CFU. In mice, desferal lowered the LD50 to less than 100 CFU, and carbon tetrachloride lowered the LD50 to approximately 1000 CFU. Twenty percent of the mice that survived had necrosis of the skin overlying the injection site. These studies demonstrate that liver damage and iron chelating agents increase mortality and necrotizing soft tissue infections caused by V. vulnificus.

Sepsis, peritonitis, and gastroenteritis developed in a 45-yr-old homosexual man 1 day after ingestion of raw oysters. The patient had chronic active hepatitis and cirrhosis with hepatitis B virus and delta-infection. He also had persistent generalized lymphadenopathy associated with HTLV-III antibody positivity. Vibrio vulnificus was isolated from the patient's blood and peritoneal fluid as well as from the same batch of oysters at the restaurant where the patient had visited. To our knowledge, this is the first report relating direct microbiologic and clinical evidence that the infection is acquired through the gastrointestinal tract by consuming raw seafood containing the pathogen. This is also the first reported case of peritonitis associated with sepsis and gastroenteritis from this organism. Patients with liver disease and other immunocompromised states should be warned about such life-threatening infections and complications associated with the consumption of raw oysters or other undercooked seafoods.

In recent years, Aeromonas species has been reported to cause extraintestinal infections with a growing frequency. Meningitis due to Aeromonas species is, however, a rare entity. We report a case of aeromonas meningitis in a 54-year-old man with a history of chronic alcoholic liver disease who, after an episode of gastroenteritis, developed an acute clinical picture characteristic of meningitis with septic shock and ecthyma gangrenosum. Aeromonas veronii (biogroup sobria) was isolated from cultures of blood as well as from cultures of stool, peritoneal fluid, skin lesion, and CSF specimens (obtained by lumbar puncture). Our review of seven additional cases of aeromonas meningitis in the world literature revealed that this condition is generally secondary to metastatic dissemination from primary bacteremia. Aeromonas meningitis, which may or may not be preceded by gastroenteritis, presents clinically as bacterial meningitis, although the presence of skin lesions may increase suspicion of the diagnosis. Third-generation cephalosporins are probably the therapy of choice for patients with aeromonas meningitis.

The role of the genus Edwardsiella in human illness is reviewed. Of the three recognized species, only Edwardsiella tarda has been demonstrated to be pathogenic for humans. Chief infections associated with this species include bacterial gastroenteritis, wound infections such as cellulitis or gas gangrene associated with trauma to mucosal surfaces, and systemic disease such as septicemia, meningitis, cholecystitis, and osteomyelitis. Risk factors that are associated with E. tarda infections include exposure to aquatic environments or exotic animals (e.g., reptiles or amphibia), preexisting liver disease, conditions leading to iron overload, and dietary habits (e.g., raw fish ingestion). Although studies indicate that this bacterium is susceptible to most commonly prescribed antibiotics, fatal gastrointestinal and extraintestinal infections have been described.

The epidemiology of 690 Vibrio infections reported in Florida during 1981-1993 is described. Most infections resulted in one of three clinical syndromes: gastroenteritis (51%), wound infections (24%), or primary septicemia (17%). Case-fatality rates were 1% for gastroenteritis, 5% for wound infections, and 44% for primary septicemia. While gastroenteritis had little seasonal variation, 91% of primary septicemias and 86% of wound infections occurred from April through October, mostly due to the seasonality of Vibrio vulnificus and Vibrio parahaemolyticus infections. Infected wounds were largely a result of occupational activities around seawater. Some 68% of gastroenteritis cases and 83% of the primary septicemias were associated with raw oyster consumption. Preexisting liver disease was present in 48% of patients with primary septicemia and was associated with a fatal outcome in both wound infections (relative risk [RR], 28.3; 95% confidence interval [CI], 6.3-127.5; P < .0001) and primary septicemia (RR, 1.9; 95% CI, 1.2-3.1; P < .01).
