Pediatric admissions to emergency departments of North-Western Italy during COVID-19 pandemic: A retrospective observational study.

Background: COVID-19 pandemic caused huge decrease of pediatric admissions to Emergency Department (ED), arising concerns about possible delays in diagnosis and treatment of severe disorders.

Methods: Impact of COVID-19 on Pediatric Emergency Room (ICOPER) was a retrospective multicentre observational study including 23 Italian EDs.All the children <18 years admitted, between March 9th and May 3rd 2020 stratified by age, priority code, cause of admission and outcome have been included and compared to those admitted in the same period of 2019.

Familial PAX8 small deletion (c.989_992delACCC) associated with extreme phenotype variability.

The PAX8 gene, mapped on 2q12-q14, encodes for a transcription factor involved in thyroid cell proliferation and differentiation. Five mutations in PAX8 have been so far described in both sporadic and rare familial forms of thyroid dysgenesis with proposed autosomal dominant inheritance, all associated with thyroid hypoplasia and/or dysfunction. Fifty-four subjects with congenital hypothyroidism detected during neonatal screening and associated with an ultrasound or scintiscan picture of thyroid dysgenesis were investigated for PAX8 mutations.

In congenital hypothyroidism bone maturation at birth may be a predictive factor of psychomotor development during the first Year of life irrespective of other variables related to treatment.

Objective: To evaluate in a cohort of infants with congenital hypothyroidism (CH): (a) the frequency of bone maturation (BM) retardation at birth and (b) whether BM delay at birth may be considered as a tool to make a prognosis of psychomotor status at the age of 1 Year, irrespective of other variables related to treatment.

Design: BM at birth, CH severity and developmental quotient (DQ) at the age of 1 Year were retrospectively evaluated in 192 CH infants selected by the following inclusion criteria: (a) gestation age ranging between 38 and 42 weeks; (b) onset of therapy within the first Month of life; (c) initial thyroxine (l-T(4)) dosage ranging from 10 to 12 microg/kg/day; (d) normalization of serum thyrotropin (TSH) levels before the age of 3 Months; (e) Monthly adjustments of l-T(4) dose during the first Year of life with serum TSH levels ranging from 0.5 to 4 mIU/l; (f) no major diseases and/or physical handicaps associated with CH; (g) availability of both thyroid scanning and knee X-rays at the time of treatment initiation; (h) availability of DQ assessment at an average age of 12 Months.

Effect of Lactobacillus GG and breast-feeding in the prevention of rotavirus nosocomial infection.

Background: Rotavirus is one of the leading etiologic agents of nosocomial infections among children. The development of preventive measures is therefore important. The efficacy of GG in the treatment of rotavirus infection has been reported in literature, but there is only one recent study about its effectiveness in prevention of infection.
