Objectives: To perform a comprehensive clinic, laboratory, and instrumental evaluation of children affected by coronavirus disease .Methods: Children with a positive result of nasopharyngeal swab for severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) underwent laboratory tests, anal and conjunctival swab, electrocardiography, lung, abdomen, and cardiac ultrasound.Twenty-four-hour ambulatory blood pressure monitoring was performed if abnormal basal blood pressure. Patients were followed-up for 6 months.Results: Three hundred and sixteen children were evaluated; 15 were finally included. Confirmed family member SARS-CoV-2 infection was present in all.Twenty-seven percent were asymptomatic. Anal and conjunctival swabs tests resulted negative in all. Patients with lower body mass index (BMI) presented significantly higher viral loads. Main laboratory abnormalities were: lactate dehydrogenase increasing (73%), low vitamin D levels (87%), hematuria (33%), proteinuria (26%), renal hyperfiltration (33%), and hypofiltration (13%). Two of the patients with hyperfiltration exhibited high blood pressure levels at diagnosis, and persistence of prehypertension at 6-month follow-up. No abnormalities were seen at ultrasound, excepting for one patient who exhibited B-lines at lung sonography.Immunoglobulin G seroconversion was observed in all at 1-month.Conclusions: Our study confirm that intra-family transmission is important. The significant higher viral loads recorded among patients with lower BMI, together with low vitamin D levels, support the impact of nutritional status on immune system.Renal involvement is frequent even among children with mild COVID-19, therefore prompt evaluation and identification of patients with reduced renal function reserve would allow a better stratification and management of patients. Seroconversion occurs also in asymptomatic children, with no differences in antibodies titer according to age, sex and clinical manifestations.

IntroductionFine needle aspiration (FNA) is the most accurate and cost-effective method for evaluating thyroid nodules. We have reported a rare complication related to the procedure: severe retropharyngeal cellulitis.Case PresentationA thirty-five-year-old female was admitted to hospital with hoarseness, laryngeal stridor and dyspnea without fever that emerged about 3 days after a first diagnostic FNA. After the procedure, the patient felt her voice became hoarse and 1 day before presentation began to have dyspnea, without fever. It had become difficult for her to swallow solids, and she felt as if food was sticking in her throat. In the emergency room, hematochemical tests and CT scan of the neck/mediastinum had been performed. This showed leukocytosis with neutrophilia and a severe cellulitis framework with involvement of the laterocervical neck area and in particular, the invasion of the retropharynx and the upper part of the mediastinum. The patient was admitted in hospital for an anti-inflammatory therapy with cortisone and antibiotic therapy.ConclusionsFor the first time to our knowledge, we have reported a severe retropharyngeal and upper mediastinum cellulitis, probably due to the FNA procedure in an immunocompetent young woman.

Several cases of a fat mass-like lesion adjacent to and/or projecting into the inferior vena cava have been presented as a normal variant of perioesophageal fat distribution or as intravascular lipoma. We report a case of a lipoma of the inferior vena cava, studied with coronal reformatted CT images, ultrasound and colour Doppler imaging, in a 78-year-old female patient.

Ependymomas outside the confines of the cranium and spinal cord are rare. Direct extension into the soft tissues of the sacrococcygeal area may occur from a primary ependymoma of the spinal cord, cauda equina or filum terminale. Alternatively they may occur as a primary pre-sacral, pelvic and abdominal tumour, or as a primary tumour of the skin and subcutaneous tissue of the sacrococcygeal area without any demonstrable connection with the spinal cord. The Authors report a case of myxopapillary ependymoma of the ischioanal fossa, demonstrated by MRI. To our knowledge, our case is the first lesion reported at this site.
