Liver tumours in children: diagnostic and therapeutic approach in the Tropics

Liver tumours in children are rare and their prognosis are poor. Through a cross and retrospective study, we examined the epidemiological, clinical and therapeutic aspects on a number of patients in our hospital to try and improve the management of cases. This study involved 66 children admitted to the pediatric oncology unit of University Hospital of Treichville in Abidjan between 1991 and 2007. The average age of children was 7.2 years and the sex ratio of 1.4. 42 children lived in the countryside and 52 children were from disadvantaged areas. 63.2% of children were not vaccinated against hepatitis B. The abdominal mass was the primary sign of discovery and these tumours were dominated in both their primitive and secondary forms by the Burkitt's lymphoma.     

Investigation d’un foyer épidémique de bilharziose urinaire dans l’école primaire du village de Guébo 2, Abidjan,Côte d’Ivoire

We report the results of an outbreak investigation of urinary schistosomiasis in 2012 among school children at Guébo 2. Among the 250 school children, 107 (42.8%) had confirmed urinary schistosomiasis. Age ≥ 10y (OR = 2.6 [1.1 to 6.2]) and self-reported bathing in the river (OR = 14.0 [4.7 to 42.5]) were associated with the presence of S.h. in the adjusted analyses. A massive deworming of the population of Guébo-1&2 was conducted as epidemicresponse.     

Serotypes and antimicrobial resistance of Salmonella enterica ssp in central Thailand, 2001-2006

This study was carried out to elucidate the epidemiological trends and antimicrobial susceptibilities against Salmonella serovars among Thai patients and asymptomatic carriers during 2001-2006 in central Thailand. A total of 1,401 human and 260 non-human isolates from various sources were included. The isolates were characterized using serotyping and antimicrobial susceptibility testing. The most common serovars in patients submitting stool samples were S. Weltevreden, S. Stanley, S. Anatum, and S. Rissen. Significantly higher odds ratios were observed in blood samples versus stool sample for S. Choleraesuis, S. Enteritidis, S. Typhimurium, and S. Typhi. Children under five years old suffered the most frequently from gastroenteritis. The patients most commonly infected with an invasive serovar were children and people from 26 to 55 years of age. Antimicrobial susceptibility data revealed that S. Schwarzengrund, S. Choleraesuis, S. Anatum, S. Stanley, S. Rissen, and S. Typhimurium were the most resistant serovars observed. The invasive serovar, S. Choleraesuis was resistant to cefotaxime and norfloxacin. Antimicrobial resistance to cefotaxime, was observed in S. Agona, S. Rissen, S. Typhimurium, S. Anatum, and S. Weltevreden. An alarmingly high frequency of resistance to third generation cephalosporins was observed. We recommend Thai authorities take action in order to prevent spread of resistant S. Choleraesuis and other serovars among animals and humans by enforcing a more strict policy on the use of antimicrobials in food animals.
