It is capable of causing a spectrum of illnesses from asymptomatic infection, to dysentery and invasive extra-intestinal conditions, the most common of which is liver abscess. Here is presented the case of a 14-month old boy presented with Fever of Unknown Origin, which after work-up was diagnosed as amebic liver abscess. Although amebiasis is more prevalent in developing countries the increasing phenomena of migration and tourism has transformed it into a global health issue. It is recommended to maintain a high index of suspicion while valuating a child with Fever of Unknown Origin.展开更多

Pharyngeal swabs were collected from 120 - 150 students in each of the three districts in Shanghai in May and December during 2015 to 2017, while emm typing and detection of 12 superantigen genes were performed to characterize the isolates. During 2015-2017, the average carriage rate in students was 5.7% (135/2,371), without significant difference between different years or districts. The carriage rate was significantly different between children from the three age groups, with 2.4% in 3 - 4 years, 5.4% in 5 - 9 years, and 9.1% in 10 - 14 years. Eight emm types were found, including emm 1, emm 4, emm 12, emm 22, emm 75, emm 89, emm 70 and emm 241, among which emm 12 accounted for 60%, and emm 1 27.5%. The predominance of emm 12 was found in each year, but the proportion of emm 12 was lower in 10 - 14 years (43.3%) than in 3 - 4 years (86.7%) and in 5 - 9 years (73.3%) (P = 0.002 and 0.003). Superantigen genes of speB, speC, speG, ssa and smeZ were found in almost all the isolates. The average carriage of S. pyogenes in population vulnerable to scarlet fever was 5.7% in Shanghai, highest in 10 - 14 years (9.1%), while emm 12 was the predominant type.展开更多

In this retrospective study carried out over a period of 12 months, we identified 20 cases of erysipelas, with an incidence of 2%, and a female predominance of 65% of cases. Age average patient age was 6 years, and the average consultation time was 5 days. The Diagnosis of erysipelas is mainly based on clinical features, including the presence of erythema associated with inflammatory signs, which were present in all cases. Satellite lymphadenopathy was observed in five cases, and fever was present in all patients. The therapeutic approach is mainly based on the administration of injectable antibiotics in children, using amoxicillin-clavulanate dose of 80 mg/kg/day in three doses.展开更多
