Dual energy X-ray absorptiometry (DXA) was used to assess lumbar spine (L2-4) and femoral neck bone mineral density (BMD) in 36 children taking either carbamazepine or valproic acid for longer than one year, for generalized idiopathic epilepsy. Patients were matched with controls. Biochemical parameters of bone mineral metabolism were also measured. BMD values at both the femur neck and lumbar spine in both the carbamazepine and valproic acid groups were not significantly different from that of the control group. Serum levels of calcium were subnormal and alkaline phosphatase levels were high in the carbamazepine group. Urinary calcium levels were significantly lower in both groups than in the control group (p< or =0.05) and also significantly lower in the valproic acid group than in the carbamazepine group (p< or = 0.05). There were no other significant biochemical changes in either group. In conclusion, the results suggest that valproic acid and carbamazepine monotherapies have minimal effects on bone mineral metabolism, but routine monitoring of risk and consideration of prophylactic vitamin D supplementation is important.

Crisponi syndrome (CS) and cold-induced sweating syndrome type 1 (CISS1) share clinical characteristics, such as dysmorphic features, muscle contractions, scoliosis, and cold-induced sweating, with CS patients showing a severe clinical course in infancy involving hyperthermia associated with death in most cases in the first years of life. To date, 24 distinct CRLF1 mutations have been found either in homozygosity or in compound heterozygosity in CS/CISS1 patients, with the highest prevalence in Sardinia, Turkey, and Spain. By reporting 11 novel CRLF1 mutations, here we expand the mutational spectrum of CRLF1 in the CS/CISS1 syndrome to a total of 35 variants and present an overview of the different molecular and clinical features of all of them. To catalog all the 35 mutations, we created a CRLF1 mutations database, based on the Leiden Open (source) Variation Database (LOVD) system (https://grenada.lumc.nl/LOVD2/mendelian_genes/variants). Overall, the available functional and clinical data support the fact that both syndromes actually represent manifestations of the same autosomal-recessive disorder caused by mutations in the CRLF1 gene. Therefore, we propose to rename the two overlapping entities with the broader term of Crisponi/CISS1 syndrome.

Bisphosphonates are used for the treatment of childhood hypercalcaemia, especially that due to malignancies. Here we report the use of intravenous pamidronate for the treatment of hypercalcaemia due to vitamin D intoxication in a 3-month-old infant. Serum calcium levels were normalised without complications. Conclusion: Pamidronate may be used in hypercalcaemia due to vitamin D intoxication in paediatric cases resistant to hydration, diuretics or corticosteroids.

As negative effects of the disease increased, the QoL of IMD patients and their parents decreased in terms of emotional, physical, and cognitive function. Application of expanded newborn scanning programs, early diagnosis, regular follow up, and family education would lessen the effects of the disease and improve the QoL of both families and children.

Based on the high frequency of hearing loss in mucopolysaccharidosis patients, early and detailed audiological evaluations are highly desirable. Therefore, regular and systematic multidisciplinary evaluations are very important.

CGM could be applied in the clinical setting to help the physician to identify hypoglycemic events, and repeated CGM may serve as a safe and useful tool for the assessment of the long-term management of patients with GSD I.

Our results show that there is an association with occult celiac disease and idiopathic short stature and that the serum anti-EmAb test is useful in identifying such cases.
