The case was that of a 21-month-old infant who presented a great inoperable Wilm's tumor that was treated with vincristine to the point of practically disappearing. Severe typhoid fever that was complicated by multiple intestinal parasitoses (ascariasis, trichuriasis, giardiasis and strongyloidiasis) appeared. Possibly, tumoral necrosis, salmonellosis and the parasitoses formed a sac that opened to the hepatic angle of the colon. Finally, multiple liver metastases were discovered and confirmed pathologically. The patient died 36 hours after surgical reexamination and liver biopsies, from causes not clearly explained. Comments are made on the diagnostic problems originated by rareness of the association of typhoid fever resistant to chloramphenicol, intestinal parasitoses and a great Wilms' tumor and the possible influence of chemotherapy and radiotherapy in the evolution of the case.

To prevent diarrhea, efforts must be directed toward decreasing environmental contamination of enteropathogens, altering exposure of persons to naturally occurring agents, or to increasing host tolerance to prevalent enteropathogens. A vaccine is feasible in the control of certain enteric infections among high risk groups: typhoid fever and cholera, in areas of hyperendemicity or during an epidemic, shigellosis in institutionalized populations that are at risk to develop illness due to known prevalent serotypes, enterotoxigenic Escherichia coli for US travelers to Latin America, and perhaps rotavirus for all children under 3 years of age. In diarrhea, the most useful form of treatment is an oral glucose/electrolyte solution, which in most cases will prevent dehydration. Lactose containing foods should be removed from the diet early in the course of diarrhea. Antimicrobial agents are necessary in the treatment of typhoid fever, are useful in the treatment of shigellosis, giardiasis, and amebiasis, and are contraindicated in intestinal salmonellosis.

Entamoeba histolytica-specific serum IgG, IgA, IgM and IgE antibodies were assayed in cases of amoebiasis in an endemic area. Patient groups consisted of amoebic liver abscess (n = 18), preabscess hepatic amoebiasis (n = 22) and amoebic colitis (n = 30). Control subjects comprised 26 asymptomatic cyst passers, 13 giardiasis cases, 20 typhoid patients and 24 non-amoebic individuals. Serum IgG was assayed by ELISA, using a monoclonal anti IgG beta-galactosidase (IgG beta-gal) conjugate, a polyclonal avidin biotin horse radish peroxidase (AB-HRP), and a polyclonal anti IgG horse radish peroxidase (IgG HRP) conjugate. IgA and IgM were assayed by the beta-gal ELISA and IgE by AB-HRP. Diagnostically significant IgG and IgA while lower IgM and IgE antibody levels were seen in extraintestinal cases. About 40% of suspected pre-abscess hepatic amoebiasis cases were confirmed by antibody estimation. All isotype levels in most dysentery cases were in the range of the controls.

The results of medical examinations carried out on 212 missionary personnel from one missionary society returning on leave to the UK are presented. The great majority of missionaries worked in developing countries. They served in 27 countries altogether and for a total of 488 person years. The commonest illnesses reported overseas were malaria (87.3 per 1000 person years at risk), diarrhoea (63.5), anxiety (63.5), depression (41.0) and giardiasis (38.9). More illnesses were reported from West Africa (698 per 1000 person years at risk) than from any other region. Ten people (4.7%) were repatriated for health reasons and 10 relatives also returned as a consequence. Sixty per cent of those returning did so because of psychiatric illness. The highest rates of immunization achieved were for yellow fever (100% of those travelling to affected countries), tetanus (93%), polio (85%), typhoid (71%) and tuberculosis (53%). The results of urinalysis (100% of adults), full blood counts (78% of adults) and stool tests (74% of all people) are reported. The study shows that the history and psychiatric examination are an important part of the medical examination of people returning from overseas. Physical examination and urinalysis did not contribute much information, although the full blood count and absolute eosinophil count were useful tests.

Acute infectious diarrhoea is a widespread cause of morbidity and mortality. Some of the major diarrhoeal diseases are cholera, typhoid fever, shigellosis (bacillary dysentery), salmonellosis, "travellers' diarrhoea", and giardiasis These diseases can be avoided with proper education, sanitation, and hygiene. However, the majority of these diseases occur most frequently in areas of the world where political and social upheaval, poverty, overcrowding, and a lack of education prevail. Although vaccines are available for some of the diseases, they are not completely effective. Antimicrobial therapy is effective in decreasing the duration and severity of diarrhoea and in reducing the likelihood of relapses, complications, and death. An antimicrobial drug for the treatment of acute infectious diarrhoeal disease must be relatively specific, effective, and safe, and it should not promote the development of resistant bacteria. Furazolidone (Furoxone) has been used for 30 years for the specific and symptomatic treatment of bacterial or protozoal diarrhoea and enteritis caused by susceptible organisms. Its effectiveness has often been shown to be comparable or superior to that of other drugs. In addition, the toxicity of furazolidone is relatively low, and it minimizes the development of resistant organisms. These characteristics should contribute to the continued use of furazolidone as a rational choice in the treatment of acute infectious diarrhoeal diseases that occur worldwide.

A retrospective survey, which is based on interviews conducted between 1975 and 1984 with 20,000 European tourists returning from 15 destinations in various climatic zones, demonstrates that travelers' diarrhea is the most frequent health problem encountered by travelers in the tropics. The incidence varied from 4% to 51%, depending on the destination. High-risk groups were persons younger than 30 years, adventurous travelers, and travelers with preexisting gastrointestinal illnesses. Illness acquired at various geographic regions showed only minor differences in chronology and symptomatology. The clinical course of travelers' diarrhea was usually short and mild. Additionally, by longitudinal and retrospective analyses, the incidence and prognosis of gastrointestinal infections of greater severity that were acquired after a short stay in a developing country, such as giardiasis, amebiasis, typhoid fever, and cholera, were evaluated; typhoid fever and cholera, in particular, were found to be quite rare.

Travelers to developing countries participated in a follow-up study of the health risks associated with short (less than three months) visits to these nations. Travelers to the Greek or Canary Islands served as a control cohort. Participants completed a questionnaire to elicit information regarding pretravel vaccinations, malaria prophylaxis, and health problems during and after their journey. Relevant infections were confirmed by the respondent's personal physician. The questionnaire was completed by 10,524 travelers; the answer rate was 73.8%. After a visit to developing countries, 15% of the travelers reported health problems, 8% consulted a doctor, and 3% were unable to work for an average of 15 days. The incidence of infection per month abroad was as follows: giardiasis, 7/1,000; amebiasis, 4/1,000; hepatitis, 4/1,000; gonorrhea, 3/1,000; and malaria, helminthiases, or syphilis, less than 1/1,000. There were no cases of typhoid fever or cholera.

In addition to gonorrhea and syphilis, both of which may develop primarily at anorectal or pharyngeal sites, a number of conditions, including Neisseria meningitidis urethritis, nonspecific urethritis, anorectal herpes, condyloma acuminatum, amebiasis, giardiasis, shigellosis, typhoid fever, enterobiasis, and hepatitis A and B, have been identified as being transmitted by male homosexual contact. Proctologic complications of anal intercourse include allergic reactions to anal lubricants, prolapsed hemorrhoids, and fistulas, and fissures. Rectosigmoid tears may result from fist, forearm, and foreign body penetration of the bowel. Physicians can best help their homosexual patients by accepting them and their relationships nonjudgmentally and by understanding their special health needs.

Empirical antimicrobial therapy is indicated in patients with diarrhoea who have high fever and systemic toxicity, dysenteric disease, or travellers' diarrhoea. Antimicrobials are essential for those with severe shigellosis and amoebiasis. They are useful or possibly useful for other forms of diarrhoeal disease including amoebiasis (milder forms), campylobacteriosis, cholera, giardiasis, shigellosis, and diarrhoea due to a variety of other laboratory-defined bacterial enteropathogens. Furazolidone is useful in infantile giardiasis and mildly effective in other forms of bacterial diarrhoea. Trimethoprim/sulphamethoxazole is effective against Shigella spp. in ost parts of the world. Erythromycin is considered the treatment of choice for campylobacteriosis. For adults, the quinolone antimicrobials represent the most useful class of drugs for bacterial enteropathogens. Several dilemmas currently exist in the area. They include the lack of drugs for the therapy of trimethoprim-resistant shigellosis in children, overuse of antimicrobials in the developing world, and the potential for post-treatment prolongation of intestinal excretion of non-typhoid salmonellae. Antimicrobial chemoprophylaxis can be used in the rare person from an industrialized area during brief travels to a tropical region who has a serious underlying medical problem, cannot exercise care in what is eaten and drunk, and will have the purpose of the trip put at jeopardy should any illness develop (even that rendered short-term by effective therapy). For most people, therapy of illness is preferred to prophylaxis.
