Acute gingivostomatitis in children: Epidemiology in the emergency department, pain, and use of codeine before its restriction.

Acute gingivostomatitis is relatively frequent in children; of viral origin, its diagnosis is usually straightforward. Acute gingivostomatitis is very painful and for many years, codeine, whose use was restricted in 2013, was widely employed in this context. The aim of this study was to ascertain the prevalence of acute stomatitis in pediatric emergency care, to evaluate the pain caused by stomatitis, and to determine the analgesic resources deployed both in the emergency department and at discharge, over the 5-year period preceding restriction of the use of codeine. METHODS: This was a retrospective study conducted in a pediatric emergency department (PED) of a university hospital between August 2008 and June 2013. RESULTS: A total of 702 children (372 herpetic gingivostomatitis [HGS], 149 herpangina [H], 181 hand, foot, and mouth disease [HFMD]) were included. Over the 5 years, one case of gingivostomatitis was identified for 303 visits to the PED. A total of 548 (78.1%) children were aged less than 36 months and the median age was 22 months. For 501 of 702 (71.4%) children, parents reported pain and/or feeding difficulties; in the HGS group, 314 of 372 (84.4%) patients had these symptoms. Of the 702 children, 48 (6.8%) were admitted to hospital. Overall, 457 (65.1%) of 702 children were given codeine before the PED visit, during the PED visit, or as a medication to take after discharge. The corresponding figures were 314 of 372 (84.4%) for the HGS group, 67 of 149 (45.0%) for the H group, and 76 of 181 (42.0%) for the HFMD group, P<0.001. CONCLUSIONS: Acute gingivostomatitis is a relative frequent reason for PED visits, and the pain and feeding difficulties that it elicits are a real challenge. Before codeine restriction, this medication played a major role in the analgesic strategy for this disease. It is essential that analgesic regimens at least as effective as codeine replace it. Morphine combined with paracetamol or the association of ibuprofen with paracetamol are options that are recommended by the French National Health Authority (HAS).

Carbon monoxide poisoning from waterpipe (narghile) smoking in a child.

Shisha smoking has spread to many countries since the 1990s and is now a global phenomenon among adolescents. Notwithstanding the connotations of conviviality of shisha smoking, it is in fact highly dangerous since the smoke inhaled contains toxic substances. Carbon monoxide (CO) poisoning carries a high risk of neurological and neuropsychological sequelae such as memory loss, impaired concentration, mood disorders, and various other symptoms. We report a case of severe CO poisoning in a 13-year-old boy after smoking shisha that caused loss of consciousness and seizure. To our knowledge, there have as yet been no reports of cases involving children. We present some epidemiological data on shisha smoking in adolescents as well as on CO intoxication.

[Duodenal duplication revealed by acute pancreatitis]. / Duplication duodénale révélée par une pancréatite aiguë.

INTRODUCTION: Duodenal duplications are rare congenital malformations whose revealing signs are highly variable and nonspecific. OBSERVATION: We report the case of a female infant who presented with neonatal acute pancreatitis complicated by recurrent ascites, profound hypoalbuminemia responsible for pleural and pericardial effusions, revealing a duodenal duplication cyst. The unusual and original clinical presentation as well as the difficulty detecting the duplication radiologically delayed the diagnosis. A prolonged medical treatment with octreotide, albumin infusions, and exclusive parenteral nutrition led to an almost total disappearance of the ascites before surgery. The outcome was favorable after surgical removal of the duplication with 1 year of follow-up. CONCLUSION: The diagnosis of duodenal duplication can be difficult and it may be necessary to repeat the ultrasound examinations. Surgical resection is delicate, especially when there is an abundant pancreatic ascites. Therefore, an adequate prolonged medical treatment to reduce this ascites is recommended before the surgery.

Casein-specific IL-4- and IL-13-secreting T cells: a tool to implement diagnosis of cow's milk allergy.

BACKGROUND: Cow's milk allergy (CMA) is a frequent food allergy in young children. The oral food challenge is the gold standard for diagnosis, and there is currently no reliable biological test. Our aim was to evaluate the diagnostic potential of a functional assay quantifying allergen-specific Th2 cells in CMA children. METHODS: A total of 29 children aged 2.8-10.5 years underwent a double-blind, placebo-controlled food challenge (DBPCFC) to cow's milk. Blood was collected before performing the DBPCFC, and peripheral mononuclear cells were cultured in an 18-h ELISpot assay with casein, α-lactalbumin, or ß-lactoglobulin. Numbers of antigen-specific IL-4- and IL-13-secreting lymphocytes and serum-specific IgE, IgG4, and total IgE levels were assessed. Receiver operating characteristic (ROC) curves were generated. RESULTS: A total of 17 (59%) children reacted to cow's milk and were therefore considered as allergic to cow's milk (CMA). The mean number of casein-specific IL-4- and IL-13-secreting T cells was higher in CMA than in non-CMA children (P = 0.009, 0.004, respectively). Moreover, it was inversely correlated with the cumulative dose of cow's milk tolerated (P = 0.003, 0.0009, respectively). ROC curve of combined IL-4 and IL-13 analysis showed an area under the curve of 0.98 (95% CI 0.90-1.06). For a cutoff of 10 IL-4- and 12 IL-13-secreting T cells, sensitivity and negative predictive value were 100%. CONCLUSIONS: Enumeration of casein-specific IL-4- and IL-13-secreting T cells appears a promising tool to improve diagnosis and, if confirmed in larger studies, could permit less frequent use of the oral food challenge.
