Epidemiology of serious bacterial infection in febrile infants under 3 months of age and diagnostic management in Mayotte.

OBJECTIVE: This study aimed to determine the prevalence of serious bacterial infections (SBIs) in infants less than 90 days old presenting with fever on arrival at the emergency department (ED), and to assess the diagnostic management of febrile infants. DESIGN: A retrospective study at Mamoudzou Hospital, Mayotte Island, French Department. SETTING: General ED in the only pediatric hospital throughout the territory PATIENTS: We included infants less than 90 days old with a history of fever and bacterial investigation evaluated in the ED between 2016 and 2018. We excluded preterm infants (gestational age < 37 weeks) and those with known immunodeficiency or previous administration of antibiotics. RESULTS: A total of 594 infants were included. In all, 105 infants (17.7%) were diagnosed with an SBI and 28 (4.7%) with an invasive bacterial infection of which 1.34% was meningitis. The most frequent SBI was pneumonia (n = 69, 11.6%) followed by urinary tract infection (UTI; n = 37, 6.2%). Predominant pathogens (excluding contaminants) were Escherichia coli (51.2% of the UTI cases), group B Streptococcus (62.5% of meningitis cases), and Staphylococcus aureus (61.5% of bacteremia cases). Seven infants presented with bacterial pneumonia due to Staphylococcus aureus with Panton-Valentine leucocidin (PVL) exotoxin production. Ill-appearing infants, clinical signs of SBI and complex chronic condition were associated with a risk of SBI (respective odds ratio [OR]: 4.6, 95% confidence interval [CI]: 3-6.9; OR: 4.2, 95% CI: 2.8-6.4; and OR: 3.2, 95% CI: 1.2-8.5). The median age for SBI was 42 days (5-90). Fever without source (FWS) occurred more often in infants under 21 days of age (48.5% vs. 31.3% in older infants, p < 0.001). The median duration of fever at home was 24 h (6-96). Concerning management, in infants aged under 21 days, there were more lumbar punctures (58.3% vs. 23% in older infants, p < 0.001) and more frequent initiation of empiric antibiotics (62.6% vs. 42.7%, p < 0.001). Length of stay was also longer in this age range (5 days vs. 3 days, p = 0.037). CONCLUSION: Delay in medical consultation in the case of fever, the risk of SBI regardless of age, and unusual epidemiology with many IBI due to Staphylococcus aureus with PVL exotoxin production are specific characteristics observed in our study. Knowledge of the current epidemiology of SBI in Mayotte would be useful for setting up a risk-stratified protocol in this population in the future.

Impact of a sports project centered on scuba diving for adolescents with type 1 diabetes mellitus: New guidelines for adolescent recreational diving, a modification of the French regulations.

BACKGROUND: Recreational scuba diving has been authorized for type 1 diabetics over 18 years old - the age of majority in France - since 2004, but it remained forbidden for younger diabetics by the French underwater federation (FFESSM). Here, we present a study to evaluate: - the conditions under which diving could be authorized for 14- to 18 year olds with type 1 diabetes; - the value of continuous glucose monitoring (CGM) while diving. A secondary objective was to monitor the impact of diving on the teenagers' quality of life. SUBJECT AND METHODS: Sixteen adolescents (14-17.5 years old) were included. Diabetes was known for 6 years (range, 1-14) and Hb1Ac was 9.0% (range, 7.7-11.9). The study was conducted in Mayotte with both capillary glycemia (CG) and CGM measurements taken during five dives. RESULTS: The average CG prior to diving was 283mg/dL and decreased by 75±76mg/dL during the dive. No hypoglycemia occurred during the dives and four episodes occurred after. Glycemia variations during dives and for the overall duration of the study were greater than for adults, most likely due to the general adolescent behavior, notably regarding diet and diabetes management. CGM was greatly appreciated by the adolescents. They had an overall satisfactory quality of life. No significant variations were observed during the entire course of the study. CONCLUSIONS: Although in need of further studies, these preliminary results show that CGM can be used while diving. CGM records show a continuous decrease of glycemia during dives. Based on these results, the French underwater federation has now authorized diving for adolescent type 1 diabetics following a specific diving protocol that includes HbA1c<8.5%, autonomous management of diabetes by the adolescent, reduction of insulin doses, and target glycemia prior to the dive>250mg/dL.

[Plant Traditional Treatment with Acalypha indica Inducing Haemolysis in Patients with G6PD Deficiency: A Frequent Circumstance in Mayotte?] / Phytothérapie traditionnelle par Acalypha indica induisant un accident hémolytique chez les patients porteurs d'un déficit en G6PD : une circonstance fréquente à Mayotte ?

A traditional treatment by plants with Acalypha indica L. can induce an intravascular haemolysis in patients with a glucose-6-phosphate-dehydrogenase (G6PD) deficiency. This information is poorly diffused in areas where the plant grows, where it is consumed for ethnomedicinal purpose and where G6PD deficiency prevalence is high; as a consequence, the probability of haemolytic accidents is presumably underestimated. It seems frequent in Mayotte according to local recent data reporting. Such accidents were previously only, and on a rare basis, reported in Sri Lanka. It seems necessary, at least in Mayotte, to inform patients, or the patients' relatives, about the potential risk in case of using traditional medicine by plants, in addition to all other circumstances able to induce haemolysis in G6PD deficiency.

Une phytothérapie traditionnelle par des remèdes contenant Acalypha indica L. est susceptible d'induire un accident hémolytique intravasculaire, potentiellement grave, chez les patients déficitaires en glucose-6-phosphate-déshydrogénase (G6PD). La toxicité potentielle de cette plante est connue, mais peu diffusée. Dans les régions où elle pousse et où coexistent un recours fréquent à la médecine traditionnelle et une prévalence élevée du déficit en G6PD, elle devrait être systématiquement recherchée. La situation semble fréquente à Mayotte, et n'avait jusqu'alors été signalée que rarement au Sri Lanka. Il semble indispensable que dans ces régions, les patients ou leurs parents soient systématiquement informés du risque potentiel en cas de recours à une médecine traditionnelle par les plantes, en plus des facteurs déclenchants habituellement recherchés.

Incidence and survival of childhood cancer in the French islands of Reunion and Mayotte (2005-2011).

The aim of this study is to describe childhood cancer incidence and survival in the French islands of Reunion and Mayotte for the period 2005-2011. Data were taken from the population-based Cancer Registry of Reunion Island. All incident cases of malignant tumours and benign tumours of the Central Nervous System diagnosed between 2005 and 2011 in children under the age of 15 and living in Reunion or Mayotte were included. A total of 236 cases were registered (176 in Reunion, 60 in Mayotte). Age-standardised incidence rates (ASRs, world standard) for all cancers were 125.0 and 101.8 per million for Reunion and Mayotte, respectively. ASRs for the main cancer groups were lower than those described in mainland France for the same period. The 5-year overall survival rate for all patients was 78.5% (95%CI 71.9- 83.7), slightly lower than that reported in mainland France.

[Air embolism on central venous access in a premature neonate, beware of the infusion device assembly! ]. / Embolie gazeuse sur cathéter central chez un nouveau-né prématuré, méfiez-vous de votre montage de perfusion !

A fatal pulmonary air embolism, confirmed by an oriented necropsy, is described in a 25-day-old premature and small-for-gestational-age neonate. The embolism was suspected after air bubbles were detected in the infusion line. The air bubbles originated from a male Luer-lock to male Luer-lock connector, which was part of a specific assembly of the perfusion line. A solution to this problem is thereby proposed. We recommend caution in using complex infusion line assemblies because such complications are probably underestimated.
