A 7 year old boy was admitted to hospital with gastroenteritis, which was complicated by an acute perforated duodenal ulcer. After oversewing of the perforation he made an uncomplicated recovery. Peptic ulceration is under-diagnosed in childhood and this leads to delay in diagnosis and appropriate management. Ulceration is associated with severe illness and viral infections, but perforation is rare.

We have cloned and sequenced the gene encoding thermostable direct hemolysin (TDH), a possible virulence factor in Vibrio parahaemolyticus gastroenteritis, from a Kanagawa-phenomenon-positive strain, T4750. This strain was found to contain two sequences (tdhA and tdhS) homologous to the tdh gene previously reported by Nishibuchi and Kaper [J. Bacteriol 162 (1985) 558-564] and Taniguchi et al. [Microb. Pathog. 1 (1986) 425-432]. Sequence homology of the coding regior between tdhA and tdhS was 97.2%. The deduced amino acid (aa) sequence of TdhA, excluding the putative signal peptide was identical to that of TDH protein purified from V. parahaemolyticus [Tsunasawa et al., J. Biochem. 101 (1987) 111-121] except for Glu118 instead of Gln118. Although the aa sequence deduced from the second gene, tdhS, differed in eight residues from the TDH protein, it agreed with the sequence of Tdh deduced from the previously cloned tdh gene. Both tdhA and tdhS expressed biologically active hemolysins in Escherichia coli. While the apparent molecular size of TDH purified from a culture supernatant of V. parahaemolyticus T4750 was identical to TdhA protein synthesized in E. coli, it was larger than TdhS. Only one band was detected in the culture supernatant of V. parahaemolyticus T4750 by Western blotting; its mobility was indistinguishable from that of purified TDH. These data suggest that tdhA is the structural gene for TDH found in the culture supernatant of V. parahaemolyticus T4750, and that there was only partial, if any, tdhS expression in the strain T4750 under the test conditions employed.

Continuous economic development and evolving social systems have created unique challenges for school health personnel in Taiwan. Due in part to economic growth and an improving health care system, average life expectancy has increased markedly for males and females since 1950. Traditional leading causes of death such as pneumonia, tuberculosis, and gastroenteritis have been replaced by accidents, neoplasms, and cardiovascular diseases. Schoolchildren suffer from various disorders that include hepatitis B, dental caries, and health problems related to scholastic pressure such as myopia, anxiety, and depression. However, new problems such as violence, substance use, and teen-age pregnancy may develop in the future. In response to the challenge, an extensive school health program has emerged that emphasizes school health instruction, school health services, and a healthful school environment. Increased attention has focused on teacher preparation in health education, and a cooperative approach to school health promotion emphasizes school, community, and interagency cooperation. Prompted by the establishment in 1980 of the Graduate Institute of Health Education, National Taiwan Normal University, school-based research initiatives have increased dramatically. Eighteen recommendations for further improvement are offered.

Between January 1985 and December 1987, seventy-five children of intravenous heroin-addicted parents (one or both) were studied. Their ages ranged from 4 days to 14 years. All patients had suffered from several pediatric diseases. Three major types of problems were found among the children studied: infectious diseases, nutritional diseases, and parental neglect and/or disinterest. The most common diagnoses at discharge were gastroenteritis (24%), pneumonia (21%), malnutrition (17%), upper airway infectious diseases (13%), septicemia (12%), child abuse (4%), acquired immunodeficiency syndrome (3%), and other infectious diseases (24%). Their parents reported hepatitis B virus infection, acquired immunodeficiency syndrome (AIDS), and alcoholism. The unemployment rate among the fathers was 37%. Sixteen percent of mothers were prostitutes. There was an imprisonment record of 19% for mothers and fathers combined. A multidisciplinary approach for this group of children would make prevention possible and care less expensive.

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.

A retrospective review was undertaken of the records of 725 children who attended the neurodevelopmental clinic at the Baragwanath Hospital in Soweto, South Africa. Most children presented at an early age (less than 2-6 years). The etiological factors were prenatal, 4 per cent; perinatal, 41 per cent; postnatal, 21 per cent. Seventy-one per cent of the perinatal factors were a result of birth related problems in full-term infants; only 22 per cent of this group were represented by premature and low birthweight infants, contrasting sharply with data from industrialized centers. Almost a third of the postnatal causes were a result of acute intracranial infections. Another 13 per cent were a result of the metabolic consequences of acute gastroenteritis. Thus a high proportion of problems were preventable through provision of adequate nutrition, mass immunization campaigns, and adequate primary health care services including antenatal and obstetric management.

A virus (strain WI61) representing a presumptive new human serotype was isolated from an 18-month-old child with gastroenteritis admitted to Children's Hospital of Philadelphia in February 1983. The WI61 virus was clearly distinguished by cross-neutralization tests from human rotaviruses of serotypes 1, 2, 3, and 4, human 69M, and representative bovine (NCDV), porcine (OSU), and chicken (Ch2) rotaviruses. Antisera generated in guinea pigs hyperimmunized to WI61 virus displayed a partial cross-reactivity with rotaviruses of human serotypes 1, 2, 3, and 4. By means of studies with reassortant rotaviruses, it was presumptively determined that the WI61 virus cross-reactive antigenic determinants are localized on the vp3 surface polypeptide coded by gene segment 4. The characteristic RNA genome electropherotype of WI61 virus was observed in 5 of 59 cases of infant gastroenteritis detected in 1983 and 1984 but has not been observed in a subsequently at Children's Hospital. Serotype WI61-specific neutralizing antibodies were observed in a majority of sera of normal adults and infants of less than 4 or greater than 12 months of age collected in the Philadelphia area. Median antibody titers to WI61 equaled or exceeded those to rotaviruses of serotype 1 or 3. Each of seven samples of commercial cow's milk exhibited neutralizing antibodies to WI61 virus at a titer greater than or equal to that to serotype 1 or 3 or bovine (strain NCDV) rotavirus. However, WI61 rotavirus did not induce disease or a specific serum-neutralizing antibody response when fed to a caesarean-derived colostrum-deprived newborn calf. WI61 rotavirus caused diarrhea in newborn mice with a 50% diarrhea-inducing dose of 10(7.0) PFU.

Of 3813 children admitted to the paediatric teaching unit in Mubarak Hospital during 1985, 716 (19%) received either therapeutic (672) or prophylactic (44) antibiotics. The indications were respiratory infections (400), urinary infections (78), septicaemia (58), meningitis (42), gastroenteritis (32), other infections (62) and prophylaxis in rheumatic fever or splenectomy (44). Penicillins were prescribed in 553 children, ampicillins being the most frequently prescribed drugs (295, 41%). Antibiotic use was assessed as unnecessary in 282 children, of whom 203 (72%) had respiratory infections. Overall mistakes were encountered in 352 cases, of which 238 (68%) were in respiratory infections and 302 (86%) involved a penicillin, single or in combination. Mistakes were also commoner with combination than with single antibiotic therapy (66% and 44%, respectively). A departmental policy for the use of antibiotics in gastro-enteritis led to their prescription in only 4% of cases. A written justification for cefotaxime reduced its use by 90%. The lack of similar policies for antibiotic use in respiratory infections leads to high rates of antibiotic use and misuse, probably world-wide.

Feces specimens from 35 patients with parasitologically confirmed giardiasis, 41 with acute gastroenteritis, 23 with acute bacillary dysentery, 40 normal persons as well as 15 jirds experimentally infected with Giardia lamblia were used for detecting parasite antigen by counterimmunoelectrophoresis (CIE). It revealed that 33 (94%) of the 35 patients with giardiasis and 14 (93%) of 15 infected jirds were positive, while the other cases, either normal person or normal jird were negative. CIE was also performed in 4 with giardiasis before and after metronidazole treatment. Prior to metronidazole administration, they were all CIE positive, but from the second day on, all became CIE negative. Apparently, detecting giardia antigen in feces specimens by CIE is not only sensitive in detecting current infection but also helpful in evaluating the effects of antigiardia agents on giardiasis.

Synthetic oligopeptides, corresponding to an amino acid sequence encoded by a potential Mr 9000 product's open reading frame (ORF-4) at the 3' terminus of the transmissible gastroenteritis virus genome, were used to generate rabbit antiserum. These antibodies produced immune complexes with an Mr 14,000 (14K) polypeptide in infected cells. The 14K product was shown by immune fluorescence to become associated with the cell nucleus, correlating with the onset of nuclear vacuolation, and suggesting a role in pathogenesis for the ORF-4 gene.
