Severity of new-onset type 1 diabetes in children and adolescents during the coronavirus-19 disease pandemic.

INTRODUCTION: ß-pancreatic cells are susceptible to SARS-CoV-2 infection and replication; this could lead to infection-related diabetes or precipitate the onset of type 1 diabetes. This study aimed to determine the severity at diagnosis, analyzing clinical and epidemiological features at debut in children under 16 years of age in the context of the SARS-CoV-2 pandemic. MATERIAL AND METHODS: A retrospective observational multicenter study was carried out in 7 hospitals of the public health network located in the south of our community. The severity at debut is compared with that of the two previous years (2018 and 2019). The level of statistical significance is set at p<0.05. RESULTS: In 2020, 61 patients debuted at the 7 hospital centres. The mean age was 10.1 years (SD: 2.6), 50.8% older than 10 years. The clinical profile at diagnosis was ketoacidosis in 52.5% compared to 39.5% and 26.5% in the previous two years (p<0.01). The mean pH (7.24 vs 7.30/7.30) and excess of bases (-11.9 vs -7.43/-7.9) was lower than in the previous two years, and the glycated haemoglobin higher (11.9 vs 11/10.6), p<0.05. At least 10% of the patients had a positive history of SARS-CoV-2 infection. CONCLUSIONS: There has been an increase in the frequency of diabetic ketoacidosis in type 1 diabetes onset during the first year of the COVID-19 pandemic.

Clinical and Molecular Description of 16 Families With Heterozygous IHH Variants.

CONTEXT: Heterozygous variants in the Indian hedgehog gene (IHH) have been reported to cause brachydactyly type A1 and mild hand and feet skeletal anomalies with short stature. Genetic screening in individuals with short stature and mild skeletal anomalies has been increasing over recent years, allowing us to broaden the clinical spectrum of skeletal dysplasias. OBJECTIVE: The objective of this article is to describe the genotype and phenotype of 16 probands with heterozygous variants in IHH. PATIENTS AND METHODS: Targeted next-generation sequencing or Sanger sequencing was performed in patients with short stature and/or brachydactyly for which the genetic cause was unknown. RESULTS: Fifteen different heterozygous IHH variants were detected, one of which is the first reported complete deletion of IHH. None of the patients showed the classical phenotype of brachydactyly type A1. The most frequently observed clinical characteristics were mild to moderate short stature as well as shortening of the middle phalanx on the fifth finger. The identified IHH variants were demonstrated to cosegregate with the short stature and/or brachydactyly in the 13 probands whose family members were available. However, clinical heterogeneity was observed: Two short-statured probands showed no hand radiological anomalies, whereas another 5 were of normal height but had brachydactyly. CONCLUSIONS: Short stature and/or mild skeletal hand defects can be caused by IHH variants. Defects in this gene should be considered in individuals with these findings, especially when there is an autosomal dominant pattern of inheritance. Although no genotype-phenotype correlation was observed, cosegregation studies should be performed and where possible functional characterization before concluding that a variant is causative.

Cefalea en racimos en edad pediátrica: descripción de cuatro casos y revisión de la bibliografía / Cluster headache in pediatric population: four case reports and review of the literature

Introducción. La cefalea en racimos es una cefalea primaria de origen trigeminoautonómico cuyo inicio en la infancia es infrecuente. Se presentan cuatro casos en los que el inicio de la sintomatología se produjo entre los 2 y los 13 años. Casos clínicos. Se incluyen tres varones y una niña con inicio a los 2, 7, 13 y 12 años, respectivamente. Los cuatro pacientes cumplen los criterios propuestos por la tercera edición de la Clasificación Internacional de las Cefaleas ICHD-III (beta). Conclusiones. A pesar de ser poco frecuente durante la edad pediátrica, la cefalea en racimos debe formar parte del diagnóstico diferencial de un niño que consulta por cefalea. Subrayamos la importancia de conocer sus criterios diagnósticos para evitar el retraso diagnóstico que se ha descrito con frecuencia. En nuestros pacientes, el tratamiento con verapamilo resultó más eficaz que el tratamiento con flunaricina. Los tratamientos con mejor respuesta en fase aguda fueron la oxigenoterapia y los triptanes (AU)

Introduction. Cluster headache is a rare cause of primary headache in children. We report four cases with a mean age of onset of 8.6, ranged from 2 to 13 years. Case reports. Three males and one female with onset at 2, 7, 13, and 12 years-old, respectively, were included. The symptoms of all patients fulfill the criteria for the diagnosis of cluster headache according to the International Society of Headache. Conclusions. Despite being rare during childhood, cluster headache should be part of the differential diagnosis of headache in childhood. This report highlights the variable features of this disorder in children, often misdiagnosed. It can be useful in making a quick diagnosis and starting the appropriate treatment early. Verapamil was more effective than flunarizine in terminating the headache in our patients. Oxygen treatment and triptans resulted the treatments with the best response in acute cluster headache (AU)
