Studies were carried out from June 1974 to May 1975 on the socio-economic status, health and nutritional status of the people in 4 villages, in the irrigation area of the Nong Wai Pioneer Agricultural Project of Khon Kaen Province, Northeast Thailand. The result obtained were compared with those in 2 non-irrigated villages in the same province, in order to identify the health and nutritional problems which might arise during the water resource development in the irrigation area. It was found that in the irrigated villages 90% of the peoples were farmers, while in the non-irrigated villages all were farmers. The socio-economic status of the people in the irrigated villages was much better than those in the non-irrigated ones. The income per family in the former was about three times greater than that in the latter. In the study of the health conditions of the villagers, the vulnerable age group including pre-school children under 7 years of age and school children in the elementary school class 1 and class 2, aged 7-9 years old, served as subjects for investigation. Haematological and physical examinations revealed many children with mild to moderate anaemia, vitamin B2 deficiency and a few cases of hepatomegaly. Anaemic children were found to be more prevalent in the non-irrigated villages than in the irrigated area. The overall parasitic infection rates in children in the irrigated and non-irrigated villages were similar with respect to severity of the infection. Hookworm infection, opisthorchiasis, strongyloidiasis and giardiasis were the leading parasitic infections, while amoebiasis was rare. Ascariasis and trichuriasis were not found. However, the first two helminthic infections had a low grade of intensity. The nutritional status of pre-school children, showed that there were more children with good growth in the irrigated villages than in the non-irrigated one. Serum proteins, albumin and globulin, and urinary urea nitrogen-creatinine ratio revealed normal findings indicating that the children had sufficient protein intake. The results of the urinary hydroxyproline-creatinine index suggested that many of the children in both groups of the villages were at marginal malnutrition status. Surveys on domestic animals including cattle, buffaloes, pigs, and field rats revealed no important zoonotic diseases except leptospirosis in a few rats. Some fish were found to harbour metacercariae of Opisthorchis viverrini, while some snails were positive for cercariae of O. viverrini, Schistosoma spindale, and Echinostoma malayanum. The overall findings indicated that the water resource development by establishing better irrigation, resulted in an improved socio-economic and nutritional status among the villagers, but health conditions and associated parasitic diseases and some nutritional deficiency still existed in the children. However, the findings from this study provide only preliminary data concerning the socio-economic status, health, and nutritional status of the villagers in the irrigation area...

Disaccharidase estimations on 115 consecutive jejunal biopsies are reported. The patients were divided into four groups: 1. Normal jejunal biopsy light microscopy, not milk intolerant, 82 cases. 2. Normal jejunal biopsy light microscopy, milk intolerant, eight cases. 3. Patients with giardiasis, 11 cases. 4. Coeliac disease patients, 14 cases. The lowest disaccharidase levels were found in coeliac disease, with giardiasis cases showing intermediate levels. Poor correlation of lactase levels with milk intolerance was found. Three cases in Group 1 showing lowered lactase levels were given metronidazole and showed remission of clinical symptoms, raising the possibility that they had undiagnosed infections with Giardia lamblia.

Catarrhal proventriculitis due to infection by an unidentified organism was diagnosed in 79 of 534 pet birds examined histologically. It was more prevalent in domestic birds (70 cases) than in imported ones (9 cases). A high incidence of the disease was encountered in budgerigars (Melopsittacus undulatus) and it was occasionally found in finches (Poephila gouldiae gouldiae), parakeets (Psittacula Krameri manillensis), Amazona parrots (Amazona aestiva aestiva) and cockatiels (Nymphicus hollandicus). The agent was a large filamentous rod, and was stained positively with Gram, GMS and PAS methods. Histologically, it induced a mild to moderate exudative or proliferative inflammation in the proventriculus. All the cases had an erosion in the gizzard. Ultrastructurally, the organism had a eukaryotic nucleus and three cell-wall layers. Concurrent infections were very common, including adenoviruses (37 cases), giardiasis (31 cases), candidiasis (13 cases), papovaviruses (11 cases) and knemidocoptic mites (11 cases).

A total of 534 psittacine and passerine birds consisting of 241 imported and 293 local birds were examined histologically. As a result, the following parasites were found: Giardia (86 cases), Knemido-coptes (26 cases), coccidia (10 cases), Ascaridia (6 cases), Cryptosporidium (5 cases), Sarcocystis (5 cases), tapeworm (4 cases), microfilaria (2 cases), Hexamita (1 case), and Spiroptera (1 case). High incidences of giardiasis and knemido-coptic infestation were detected in the local birds, but rarely in the imported birds. Giardial trophozoites were observed mainly in the duodenum of budgerigars (Melopsittacus undulatus). Knemidocoptic mites burrowed into the epidermis producing proliferative dermatitis in 25 budgerigars and 1 African Grey Parrot (Psittacus erithacus erithacus). This ectoparasite often infested the skin around the cloaca. Coccidiosis was seen only in the small intestines of the finch (Poephila gouldiae gouldiae), African Grey Parrot, Rainbow lory (Trichoglossus haematodus), Indian Ring-necked parakeet (Psittacula krameri manillensis) and peach-faced lovebird (Agapornis roseicollis). Two parrots (Amazona aestiva aestiva and Psittacus erithacus erithacus) and two budgerigars had intestinal cryptosporidiosis. Conjunctivitis associated with cryptosporidial infection was seen in a lovebird. Sarcocystis cysts containing crescent-shaped bradyzoites were found not only in the thigh and breast but also in the heart and cloacal muscles. Other organisms such as Ascaridia, tapeworm, microfilaria, Hexamita, and Spiroptera were clinically less significant. However, infections such as Giardia and Cryptosporidim might have zoonotic implications.

We studied 200 patients assisting at the Allergy Department and the Gastroenterology Department in "Hermanos Ameijeiras" Clinical-Surgical Hospital. They were clinically and immunologically tested for giardiasis through duodenal fortis or gall bladder drainage and total IgE serum levels. All patients underwent intradermal and skin prick tests with Giardine allergenic extract. These skin tests showed high sensitivity and increased specificity. Thus, our procedure in diagnosis is accurate, accessible and economical.

The tetracyclines are effective in the treatment of Chlamydia, Mycoplasma pneumoniae, and rickettsial infections and also can be used for gonococcal infections in patients unable to tolerate penicillin. These drugs may cause gastrointestinal irritation, diarrhea, phototoxic dermatitis, and vestibular damage, and fatal reactions due to hepatotoxicity have occurred in pregnant women. Chloramphenicol has a broad spectrum of bacteriostatic activity, but its association with suppression of the bone marrow and aplastic anemia has relegated it to a historical role. Erythromycin is the drug of choice for the treatment of infections caused by M. pneumoniae, Legionella species, group A beta-hemolytic streptococci, and Streptococcus pneumoniae. The frequency of serious adverse effects associated with the use of erythromycin is low; dose-related epigastric distress may occur. Clindamycin is bactericidal to most nonenterococcal gram-positive aerobic bacteria and many anaerobic microorganisms. Although historically it was a frequent cause of antibiotic-associated diarrhea and colitis, clindamycin is considered an excellent alternative to beta-lactam antibiotics for treatment of many staphylococcal infections, and it has therapeutic utility in anaerobic infections and in several protozoan infections in immunosuppressed patients. Metronidazole is efficacious for treating nonpulmonary anaerobic infections, various parasitic infections (trichomoniasis, amebiasis, and giardiasis), nonspecific vaginitis, and Clostridium difficile-mediated colitis. With use of metronidazole, mild side effects such as epigastric discomfort, diarrhea, reversible neutropenia, and allergic-type cutaneous reactions may occur.

For the 2-year period 1989-1990, 16 states reported 26 outbreaks due to water intended for drinking; an estimated total of 4,288 persons became ill in these outbreaks. Giardia lamblia was implicated as the etiologic agent for seven of the 12 outbreaks in which an agent was identified. The outbreaks of giardiasis were all associated with ingestion of unfiltered surface water or surface-influenced groundwater. An outbreak with four deaths was attributed to Escherichia coli O157:H7, the only bacterial pathogen implicated in any of the outbreak investigations. An outbreak of remitting, relapsing diarrhea was associated with cyanobacteria (blue-green algae)-like bodies, whose role in causing diarrheal illness is being studied. Two outbreaks due to hepatitis A and one due to a Norwalk-like agent were associated with use of well water. Eighteen states reported a total of 30 outbreaks due to the use of recreational water, which resulted in illness for an estimated total of 1,062 persons. These 30 reports comprised 13 outbreaks of whirlpool- or hot tub-associated Pseudomonas folliculitis; 13 outbreaks of swimming-associated gastroenteritis, including five outbreaks of shigellosis; one outbreak of hepatitis A associated with a swimming pool; and three cases of primary amebic meningoencephalitis caused by Naegleria. The national surveillance of outbreaks of waterborne diseases, which has proceeded for 2 decades, continues to be a useful means for characterizing the epidemiology of waterborne diseases.

The epidemiology, clinical presentations, and recent developments in understanding Giardia are reviewed. Diagnosis is discussed in light of recent studies that challenge the clinician's approach to the diagnosis of enteric parasites, including giardiasis, and that demonstrate the need for further evaluation on the basis of cost-effectiveness, as well as reliability and clinical practicality. The overall effectiveness and difficulties associated with present standard diagnostic methods and the more recently developed immunologic approaches to diagnosis in giardiasis are reviewed.

Data are presented on scanning electron microscopy (SEM) on small intestinal biopsies of children with chronic diarrhea. In particular, there were 230 patients aged 3 months to 13 years with the following diagnoses: chronic nonspecific diarrhea, cow's milk protein intolerance, soy protein intolerance, giardiasis, cystic fibrosis, gluten-sensitive enteropathy, isolated lactase deficiency, isolated sucrase-isomaltase lactase deficiency, microvillus inclusion disease, rotavirus enteritis, protracted diarrhea of infancy, chylomicron retention disease, visceral myopathy and villous asthenia. Examination of biopsied intestinal mucosa by SEM has yielded important new information and insights on structural pathology and ultrastructural topography. Many of the observed changes helped to better understand the pathophysiology of some of the diarrheal disorders. SEM was also able to detect new features such as mycoplasma-like microorganisms and the absence of the glycocalyx. To adequately assess small bowel mucosal pathology at the ultrastructural level, scanning electron microscopy is an indispensable tool.

This overview provides a discussion of the special concerns of sexually transmitted diseases (STDs) for women, particularly because of its asymptomatic character; screening; primary prevention; e.g., abstinence, selection of sexual partners restriction of sexual activities, use of barriers (condoms, vaginal spermicides, diaphragm in conjunction with spermicides), and vaccines; and the role of the gynecologist in StD prevention. Gonorrhea and chlamydial infection are usually asymptomatic STD infections in women; long term sequelae are pelvic inflammatory disease (PID), infertility, and pregnancy complications. There is an increased risk of cervical cancer. Infection is lifelong for herpes simplex virus (HSV) and HIV and malingering for chronic hepatitis B (HPB). Genital human papillomavirus (HPV) and HSV infections cannot be identified serologically. The fetus can be fatally or severely affected by STDs. Abstinence is the only effective prevention for STDs. Likelihood of infection may be reduced by limiting partners, but how partners are chosen and knowledge of infection is a more important determinant. Partners need to be asked about current symptoms, history of STDs, multiple partners, and history of known STD partners, as well as past history of homosexual activity, intravenous drug use, hemophilia, and previous exposure to high-risk persons for STDs. Visible genital warts or lesions, wartlike growths, ulcers, or rash need explanations. Avoidance of oral anal and digital anal activity reduces transmission of hepatitis A, giardiasis, amebiasis, and shigellosis. Any mechanical barrier that remains intact should reduce the risk of STD; barriers specifically covering the cervix are excellent. Condom use is effective when used as follows: 1) at the onset of sexual activity, 2) without petroleum jelly or baby oil on latex, 3) with care of fingernails which may tear holes, 4) with complete withdrawal of the penis before complete detumescence, and 5) with a withdrawal hold at the base of the penis. Spermicides, such as nonoxynol 9, are effective against STDs. Diaphragm use with spermicide may be effective because of the spermicide. There is a reduced risk of transmission of HSV or HPV to a partner. Vaccines are only available for hepatitis B. Obstetrics and gynecology residency training in STDs in unavailable in 4 out of 5 medical schools, and gynecologists are ethically obligated to accurately inform about STD diagnosis, treatment, and diagnosis.
