MATERIALS AND METHODS: In this retrospective review, data collected during 2006-2015 from the medical charts of patients with evidence of infection, caused by any Salmonella serogroup or clinical form, were examined. We aimed to assess the clinical manifestations, antibiotic susceptibility, and antibiotic use in children with Salmonella gastroenteritis over the ten years' period.
RESULTS: A total of 419 patients had non-typhoidal Salmonella infection. Four-hundred (95.5%) patients were diagnosed with acute gastroenteritis, which was common in children aged <12 months (72.3%). The clinical features of patients with gastroenteritis included fever (74.5%), diarrhoea with bloody mucus (60.5%), watery diarrhoea (39.5%), and vomiting (19.8%). Serogroup B was most commonly detected in the stool specimens. The susceptibility of non-typhoidal Salmonella to ampicillin, norfloxacin, and co-trimoxazole was 36.3%, 98.0%, and 80.5%, respectively. Serogroup B was the most resistant strain, which was sensitive to ampicillin in only 21.6% of specimens, while it showed high susceptibility to norfloxacin and co-trimoxazole (98.1 and 84.0%, respectively). Third-generation cephalosporin and fluoroquinolone were most commonly prescribed.
CONCLUSIONS: Acute gastroenteritis is the most common form of Salmonella infection. Gastroenteritis caused by serogroup B is still the most common infection, which mostly occurs among infants under one year of age. The majority of stool specimens were still susceptible to antimicrobial agents, especially fluoroquinolone and cotrimoxazole; however, there was an overuse of antibiotics without proper indications.
MATERIALS AND METHODS: All dengue patients hospitalised at King Chulalongkorn Memorial Hospital, Bangkok, Thailand during 1987-2008 and aged 0-15 years were included. All parameters were compared between patients in two groups: aged 0-2 years and >2-15 years.
RESULTS: Of the 2,221 children who were diagnosed with dengue, 179 were children aged 0-2 years compared with 2,042 children aged >2-15 years. The early childhood group presented significantly more frequently with hepatomegaly, drowsiness, diarrhoea, rash, convulsions, splenomegaly, and unusual manifestations. Dengue fever (DF) was more common in the early childhood group and dengue haemorrhagic fever (DHF) was less common. The mortality rate of the early childhood group was 1.67%, which was significantly higher than that of the comparative group. Approximately 65% of study subjects were serologically proven to have primary infection, compared to 9.8% of older children.
CONCLUSIONS: Clinical manifestations of dengue infection in early childhood are different in some aspects from those of dengue infection in older children, and mortality is higher. To effectively prevent dengue infection morbidity and mortality in children, it is essential that clinicians correctly recognize and diagnose dengue infection, particularly in early childhood.
