Pendred syndrome, or not Pendred syndrome? That is the question

Pendred syndrome (PDS) is the most common form of syndromic Hearing Loss (HL), characterized by sensorineural HL, inner ear malformations, and goiter, with or without hypothyroidism. SLC26A4 is the major gene involved, even though ~50% of the patients carry only one pathogenic mutation. This study aims to define the molecular diagnosis for a cohort of 24 suspected-PDS patients characterized by a deep radiological and audiological evaluation. Whole-Exome Sequencing (WES), the analysis of twelve variants upstream of SLC26A4, constituting the "CEVA haplotype" and Multiplex Ligation Probe Amplification (MLPA) searching for deletions/duplications in SLC26A4 gene have been carried out. In five patients (20.8%) homozygous/compound heterozygous SLC26A4 mutations, or pathogenic mutation in trans with the CEVA haplotype have been identified, while five subjects (20.8%) resulted heterozygous for a single variant. In silico protein modeling supported the pathogenicity of the detected variants, suggesting an effect on the protein stabilization/function. Interestingly, we identified a genotype-phenotype correlation among those patients carrying SLC26A4 mutations, whose audiograms presented a characteristic slope at the medium and high frequencies, providing new insights into PDS. Finally, an interesting homozygous variant in MYO5C has been identified in one patient negative to SLC26A4 gene, suggesting the identification of a new HL candidate gene

Neck stiffness and bone osteolytic lesion in a 3-years old child: a case report

Abstract Background Neuroblastoma is the most frequent extracranial solid tumor occurring in childhood, representing approximately 28% of all cancers diagnosed in infants. Signs and symptoms of neuroblastoma vary with the site of development of the tumor and can mimic other diseases due to its extreme clinical variability. However, torticollis is not reported in the medical literature as a leading symptom of neuroblastoma. Case presentation Here we report the case of a 3 years-old girl with fever and neck stiffness. Blood tests revealed a mild anemia and a rise in inflammatory markers. CT-scan showed a solid, heterogeneous, predominantly hypodense surrenal mass with eccentric calcification and extensive inhomogeneity of the vertebral metamers. Blood tests revealed raised serum levels of Neuron-Specific Enolase. At the 24-hours urine collection urinary catecholamines were greatly increased. A course of chemotherapy for neuroblastoma was promptly started with immediate clinical improvement. Conclusions This case shows that the presence of torticollis could be a chief complaint of neuroblastoma. To our knowledge, neuroblastoma is not mentioned among life-threatening underlying conditions of torticollis in most recent literature reviews

Ogilvie syndrome in a 8 year old girl after laparoscopic appendectomy

Abstract Background Ogilvie’s syndrome is described in the adult population, but rarely seen in children. Case presentation We present a case of a girl who suffered acute colonic pseudo-obstruction after laparoscopic appendectomy. Conclusions Ogilvie’s syndrome, although rare in the pediatric population, should be considered as possible diagnosis after a surgical procedure in presence of persisting subocclusive symptoms and radiological signs of massive colonic dilatation without mechanical obstruction

Low incidence of SARS-CoV-2, risk factors of mortality and the course of illness in the French national cohort of dialysis patients

International audienceThe aim of this study was to estimate the incidence of COVID-19 disease in the French national population of dialysis patients, their course of illness and to identify the risk factors associated with mortality. Our study included all patients on dialysis recorded in the French REIN Registry in April 2020. Clinical characteristics at last follow-up and the evolution of COVID-19 illness severity over time were recorded for diagnosed cases (either suspicious clinical symptoms, characteristic signs on the chest scan or a positive reverse transcription polymerase chain reaction) for SARS-CoV-2. A total of 1,621 infected patients were reported on the REIN registry from March 16th, 2020 to May 4th, 2020. Of these, 344 died. The prevalence of COVID-19 patients varied from less than 1% to 10% between regions. The probability of being a case was higher in males, patients with diabetes, those in need of assistance for transfer or treated at a self-care unit. Dialysis at home was associated with a lower probability of being infected as was being a smoker, a former smoker, having an active malignancy, or peripheral vascular disease. Mortality in diagnosed cases (21%) was associated with the same causes as in the general population. Higher age, hypoalbuminemia and the presence of an ischemic heart disease were statistically independently associated with a higher risk of death. Being treated at a selfcare unit was associated with a lower risk. Thus, our study showed a relatively low frequency of COVID-19 among dialysis patients contrary to what might have been assumed
