Case report: Exploring under the tip of the iceberg: A case series of “self-limiting” multisystem inflammatory syndrome in children

Multisystem inflammatory syndrome in children (MIS-C) is a serious condition triggered by SARS-COV-2 infection, characterized by persistent fever, multiorgan dysfunction, and increased inflammatory markers. It requires hospitalization and prompt treatment, with nearly 60% of the cases needing intensive care and 2% fatality rate. A wide spectrum of clinical characteristics and therapeutic approaches has been reported in MIS-C. We describe a series of four patients with MIS-C, defined according to the current case definitions, with a self-limiting course and no need for immunomodulatory treatment (“self-limiting MIS-C”). Few data about self-limiting MIS-C are available to date and no information on medium- and long-term outcome of this subset of patients has been reported. Although limited in size, our experience provides new insights into the MIS-C syndrome, highlighting an underestimated aspect of the disease that may have significant therapeutic implications

Usefulness of fetal three-dimensional ultrasonography for detecting of congenital heart defects and associated syndromes.

Abstract Congenital heart defects (CHDs) occur in 1% of live-born infants and frequently are associated with extracardiac malformations. This study aimed to assess the feasibility and accuracy of three-dimensional ultrasonography (3DUS) in fetuses with CHD and to investigate whether 3DUS can add information about the heart and general fetal morphology that shows other congenital malformations or suggests syndromes. For 30 fetuses affected by CHD, 3DUS was performed using a Sonos 7500 ultrasound machine with a cardiac 3D transducer. In 44% of the exams, 3DUS was completely diagnostic for the CHD, providing additional information in 28% of the exams. Furthermore, 3DUS showed 82% of associated malformations, providing the complete diagnosis in 57% of the cases and helping with recognition of syndromes in others. The diagnostic accuracy of 3DUS was superior, with a higher number of acquisitions per exam. Performance was better in fetuses younger than 24 weeks for general morphologic details and in fetuses older than 24 weeks for the heart morphology

Severe hypoglycemia and ketoacidosis over one year in Italian pediatric population with type 1 diabetes mellitus: A multi center retrospective observational study

BACKGROUND AND AIMS:Evaluation of incidence and correlates of severe hypoglycemia (SH) and diabetes ketoacidosis (DKA) in children and adolescents with T1DM. METHODS AND RESULTS:Retrospective study conducted in 29 diabetes centers from November 2011 to April 2012. The incidence of SH and DKA episodes and their correlates were assessed through a questionnaire administered to parents of patients aged 0-18 years. Incidence rates and incident rate ratios (IRRs) were estimated through multivariate Poisson regression analysis and multilevel analysis. Overall, 2025 patients were included (age 12.4 \ub1 3.8 years; 53% males; diabetes duration 5.6 \ub1 3.5 years; HbA1c 7.9 \ub1 1.1%). The incidence of SH and DKA were of 7.7 and 2.4 events/100 py, respectively. The risk of SH was higher in females (IRR = 1.44; 95%CI 1.04-1.99), in patients using rapid acting analogues as compared to regular insulin (IRR = 1.48; 95%CI 0.97-2.26) and lower for patients using long acting analogues as compared to NPH insulin (IRR = 0.40; 95%CI 0.19-0.85). No correlations were found between SH and HbA1c levels. The risk of DKA was higher in patients using rapid acting analogues (IRR = 4.25; 95%CI 1.01-17.86) and increased with insulin units needed (IRR = 7.66; 95%CI 2.83-20.74) and HbA1c levels (IRR = 1.63; 95%CI 1.36-1.95). Mother's age was inversely associated with the risk of both SH (IRR = 0.95; 95%CI 0.92-0.98) and DKA (IRR = 0.94; 95%CI 0.88-0.99). When accounting for center effect, the risk of SH associated with the use of rapid acting insulin analogues was attenuated (IRR = 1.48; 95%CI 0.97-2.26); 33% and 16% of the residual variance in SH and DKA risk was explained by center effect.CONCLUSION:The risk of SH and DKA is mainly associated with treatment modalities and strongly depends on the practice of specialist centers
