Early-Onset Infection Caused by Escherichia coli Sequence Type 1193 in Late Preterm and Full-Term Neonates.

Using whole-genome sequencing, we characterized Escherichia coli strains causing early-onset sepsis (EOS) in 32 neonatal cases from a 2019-2021 prospective multicenter study in France and compared them to E. coli strains collected from vaginal swab specimens from women in third-trimester gestation. We observed no major differences in phylogenetic groups or virulence profiles between the 2 collections. However, sequence type (ST) analysis showed the presence of 6/32 (19%) ST1193 strains causing EOS, the same frequency as in the highly virulent clonal group ST95. Three ST1193 strains caused meningitis, and 3 harbored extended-spectrum ß-lactamase. No ST1193 strains were isolated from vaginal swab specimens. Emerging ST1193 appears to be highly prevalent, virulent, and antimicrobial resistant in neonates. However, the physiopathology of EOS caused by ST1193 has not yet been elucidated. Clinicians should be aware of the possible presence of E. coli ST1193 in prenatal and neonatal contexts and provide appropriate monitoring and treatment.

Usefulness of routine early œsophagogram after primary repair of œsophageal atresia: a multicenter study.

BACKGROUND: Advances in surgical and neonatal care have led to improved survival of patients with œsophageal atresia (OA) over time. Morbidity remains significant, with one-third of patients being affected by a postoperative complication. Several aspects of management are not consensual, such as the use of œsophagogram before starting oral feeding. METHODS: We conducted a multicenter retrospective study, including all children with OA that underwent a primary anastomosis in the first days of life, between 2012 and 2018 in five French centers, to determine the usefulness of postoperative œsophagogram during the 10 days after early primary repair of OA to diagnose the anastomotic leak and congenital œsophageal stenosis. RESULTS: Among 225 included children, 90 (40%) had a routine œsophagogram and 25 (11%) had an anastomotic leak, clinically diagnosed before the scheduled œsophagogram in 24/25 (96%) children at median postoperative day 4. Ten patients had associated congenital œsophageal stenosis diagnosed on the œsophagogram in only 30% of cases. CONCLUSION: Early œsophagogram is rarely useful in the diagnosis of an anastomotic leak, which is clinically diagnosed before performing an œsophagogram in the majority of cases. The need for a postoperative œsophagogram should be evaluated on a case-by-case basis. IMPACT: Early œsophagogram is not helpful in the diagnosis of an anastomotic leak in the majority of cases. An anastomotic leak is most often diagnosed clinically before performing an œsophagogram. Early postoperative œsophagogram could be helpful for the diagnosis of congenital œsophageal stenosis. However, dysphagia occurs later and early diagnosis of congenital œsophageal stenosis has no impact on the management and outcome of asymptomatic children. Indication of postoperative œsophagogram has to be evaluated on a case-by-case basis.

[Acute polyradiculoneuropathy in children: the Kairouan pediatric department experience. Report of 22 cases]. / Syndrome d'obésité hypoventilation et syndrome d'apnées de sommeil : quel type d'association?

BACKGROUND: Guillain-Barre Syndrome (GBS) is an acute polyradidulonevritis which is primitive inflammatory and demyelinisant. It represents the most frequent cause of acute peripheric paralysis of the child. AIM: To study the epidemiologic, clinic, electromyographic, outcome and therapeutic features of this disease. METHODS: 22 cases of GBS were reported in the pediatric department of Ibn El Jazzar's hospital of Kairouan from January 1990 to September 2009. RESULTS: The GBS represents a hospital frequency of 0.45 %o . The mean age of the patients was 6.88 years with a sex ratio of 1.2. The prodromic infectious manifestations were observed in 54.5% of cases. The clinic symptomatology was the muscular deficiency observed in all cases with absence of deep reflex an albumincytologic dissociation was observed in 12 cases. The electromyographic manifestations were: an axonal disorder in four cases, axonomyelinic in eight cases and myelinic in seven cases. A specific therapy by intravenous polyvalent immunoglobulin was prescribed for 14 patients. The evolution was favourable in 10 cases with total recovery three cases of drop foot gait were observed, seven patients were lost to follow up and two patients are dead. CONCLUSION: GB syndrome is the most frequent cause of child acute primitive distal paralysis, since acute polio has been eradicated. Acute Respiratory disorder is the most severe complication this syndrome can lead to in 5% of cases. The course of the disease is often mild and severe scars are only encountered in 5 to 10 % of cases. Indeed, the use intravenous immunoglobulin has utterly changed prognosis.

Risk factors for mortality of children with zoonotic visceral leishmaniasis in Central Tunisia.

BACKGROUND: Zoonotic visceral leishmaniasis (ZVL) caused by Leishmania infantum is endemic with an epidemiological profile of a paediatric disease in Tunisia. In the context of a high fatality rate, identifying risk factors for in-hospital mortality in children treated for ZVL is of major epidemiological importance. DESIGN: A retrospective (case-control) study included 230 immuno-competent children diagnosed and confirmed with primary ZVL in the paediatric department of the University Hospital of Kairouan between 2004 and 2014. Forty-seven per cent (47%) were children under 18 months of age, and with a male / female ratio of 1.01:1. RESULTS: The overall case-fatality was 6% (n = 14). The risk factors for in-hospital death identified by a multivariate analysis were: bleeding at admission (OR = 25.5, 95% CI: 2.26-287.4; p = 0.009), white cell count less than 4000/mm3 (OR = 5.66, 95% CI: 1.16-27.6; p = 0.032), cytolysis (OR = 28.13, 95% CI: 4.55-173.6; p < 0.001), and delay between onset of symptoms and admission ≥ 15 days (OR = 11, 95% CI: 1.68-72; p = 0.012). CONCLUSION: The results strongly suggest that paediatric patients admitted 15 days after onset of symptoms, with bleeding, white cell counts below 4,000/mm3, and cytolysis at admission should be considered severe cases and subsequently, they are at high risk of mortality. A better understanding of factors associated with death of children from ZVL may contribute to decrease mortality.
