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.

The purified Schistosoma mansoni adult microsomal antigen, MAMA, was used in the quantitative single-tube kinetic dependent enzyme-linked immunosorbent assay (k-ELISA) to measure antibody levels of various human patient sera. The 511 serum specimens tested were from patients with both homologous and heterologous infections. Sera from U.S., Egyptian, Brazilian, and Puerto Rican patients infected with S. mansoni reacted strongly with MAMA. Chinese patients infected with S. japonicum, and Nigerians or Egyptians infected with S. haematobium produced much lower responses to this antigen than those infected with S. mansoni. Sera from patients with echinococcosis, filariasis, paragonimiasis, clonorchiasis, trichinosis, amebiasis, and hepatitis and from healthy uninfected control individuals generally contained no detectable antibodies against this antigen. The S. mansoni adult microsomal antigen, MAMA, therefore, appears to be a highly potent and specific reagent for the serodiagnosis of S. mansoni infections.

As early syphilis becomes more uncommon in the community, it will present frequently to the tertiary hospital as a diagnostic problem. Twenty patients with classic signs and symptoms of primary and secondary syphilis in whom the correct diagnosis was initially missed are presented. The importance of a routine admission Venereal Disease Research Laboratory test (VDRL) in making the correct diagnosis is emphasized. The laboratory techniques for diagnosing syphilis and recommended treatment schedules are presented. Clinical manifestations of herpes progenitalis, problems with pregnancy and association with cervical carcinoma are also presented. Enteric diseases (hepatitis, shigellosis, giardiasis and amebiasis) as sexually transmitted diseases in homosexual men are summarized.

Hepatitis viruses, enteric pathogens, and anorectal infections may commonly be transmitted by various sexual practices. Because of their larger numbers of sexual partners and sexual practices such as anilingus and anal intercourse, homosexual men are at particularly high risk of acquiring hepatitis B, giardiasis, amebiasis, shigellosis, campylobacteriosis, and anorectal infections with Neisseria gonorrhoeae, Chlamydia trachomatis, Treponema pallidum, herpes simplex virus, and human papilloma viruses. The evidence for sexual transmission of these infections as well as their diagnosis and treatment are discussed.

The causes of cholestasis in 276 patients with a total of 296 lesions were studied. Extrahepatic cholestasis was found in 58.4 percent of the patients, and 41.6 percent had intrahepatic cholestasis. Malignant disease was found in 34.8 percent of the patients (extrahepatic cholestasis in 20 and intrahepatic cholestasis in 70). Cholangiocarcinoma, especially the hilar intrahepatic type, seems to be the most prevalent in the medical literature. It is possible that the combination of opisthorchiasis and carcinogenic agents, such as nitrosamines, induce a precancerous stage at the hilar area. Some unknown factors, may be the immune system in immune surveillance that act as a catalyst leading to malignant transformation. Acute calculous cholecystitis, choledocholithiasis, and intrahepatic stones are more common in Thailand than in the western countries, and their causes have been discussed herein. The composition of stones is also different; pigment stones are found more often in Thailand. These differences between the western and oriental types of biliary calculi are significant in regard to diagnostic approach and management, and morbidity and mortality. In Thailand, Opisthorchiasis viverrini has significant influence in the development of several cholestatic diseases, such as hilar intrahepatic cholangiocarcinoma, biliary calculi, opisthorchiatic intrahepatic cysts, and aggregated dead opisthorchiatic worms blocking the biliary system. In tropical countries, infectious diseases such as virus B hepatitis; severe systemic infectious diseases such as salmonellosis; and amebiasis and tuberculosis were also important causes of intrahepatic cholestasis. In the category of congenital anomalies, the prevalence of choledochal cysts was higher than in the United States. The prevalence of other forms of congenital anomalies of the biliary system is unknown, but may be similar to the prevalence of choledochal cysts.

Amoebiasis is a common cause of liver disease usually presenting as single large or multiple smaller abscesses. Cases with granulomatous hepatitis have rarely been described. We report the case of a 7-year-old girl with amoebic granulomatous hepatitis in which multiple liver abscesses were demonstrated by MRI. A total of 14 abscesses were identified, ranging from 5 mm to 3 cm in diameter. The largest lesions appeared to T2-weighted images as heterogeneous, low-intensity areas surrounded by a double-layered wall, the inner layer of which was hyperintense and the outer layer hypointense. These signs, which have never been described in classic amoebic abscess, represent, we believe, a pattern of hepatic granulomatous amoebiasis lesions. We suggest that MRI should always be performed in cases of amoebic infection.

Early appearance of clinical jaundice is rare presentation in enteric fever. Although abnormal biochemical tests suggestive of hepatic involvement has already been suggested in 23-60 per cent of cases. The early hepatic changes have been attributed to generalised bacteraemia, persistence of hepatomegaly and hepatic lesion during pyrexial stage. But the typhoid hepatitis has been ignored as a clinical entity. In this report the importance of typhoid hepatitis and its clinical significance for the diagnosis of enteric fever is highlighted, particularly at places where viral hepatitis and hepatic amoebiasis are usually common and enteric fever is endemic.

Ornidazole is a commonly prescribed antiparasitic drug for parasitic infestations, including amoebiasis, giardiasis and Trichomonas vaginalis. Several cases of antibiotic-induced autoimmune hepatitis (AIH) or AIH-like syndrome have been reported recently. In this report, we describe a 35-year-old woman with two relapses of AIH induced by ornidazole prescribed for diarrhoea and vaginal infection.

Hispanic immigrants are an increasing portion of the United States (US) population. In addition to being at risk for diseases common in the US-born population, Hispanic immigrants also are at risk for infections that do not usually occur in the US-born population. Thus, such diseases as tuberculosis, neurocysticercosis, brucellosis, typhoid fever, malaria, amebiasis, viral exanthems, and hepatitis need to be considered in Hispanics who present with fever or focal lesions. When included in the differential diagnosis, most of these infections can be readily diagnosed and treated with currently available methods.

The article focuses on the Indian initiative of making kits for diagnosis of various infectious and non-infectious diseases as well as reproductive hormones and hormones in various other endocrine disorders. Indigenous diagnostic kits for the detection of various infections such as filariasis, typhoid, amebiasis, Japanese encephalitis, hepatitis, HIV, dengue, leishmaniasis, malaria, rabies, toxoplasmosis, rotavirus, and group A streptococci have been developed. Agreements to transfer the know-how of some of these leads to industries have been signed. The know-how of enzyme-linked immunosorbent assay (ELISA) for detection of hepatitis C has been successfully transferred to industry and is being commercially produced. For detection of HIV-1 and HIV-2, indigenous diagnostic kits based on three different formats, namely ELISA, Western blot and rapid test have been developed and are being commercially produced by Indian industries. The factors influencing the successful transfer of laboratory-scale diagnostic assays from academia to industry and their commercial exploitation have been discussed. Indian scientists have made seminal contributions in exploring the possibility to develop an effective and safe contraceptive vaccine to control the increasing human population of India. Achieving contraception by means of vaccine is a novel approach, which entails generation of a specific antibody response against antigens critically involved in the process of mammalian reproduction. In India, three major programs on contraceptive vaccines based on the beta-subunit of human chorionic gonadotrophin ((beta)hCG) for women, ovine follicle stimulating hormone (oFSH) for men, and riboflavin carrier protein for both males and females have been initiated. The work at the National Institute of Immunology, New Delhi on contraceptive vaccine for women, based on (beta)hCG, has demonstrated, for the first time, that it is feasible to regulate fertility by such an approach. Basic research being carried out to achieve immunocontraception by interfering at sperm-oocyte interaction level has been briefly discussed. These developments are still at the research stage. In addition to advances in the area of contraceptive vaccines, a non-steroidal contraceptive oral pill has been developed by Central Drug Research Institute, Lucknow, commercially produced by two Indian pharmaceutical companies and has been incorporated in the National Family Welfare Program. Another interesting approach for fertility regulation in male has been developed in India, which involves vas occlusion with styrene maleic anhydride (SMA) and is currently undergoing clinical trials in human subjects.
