Case ReportsAN INFANT WITH IDIOPATHIC HYPERCALCIURIA AND NEPHROLITHIASIS ASSOCIATED WITH CYP24A1 ENZYME POLYMORPHISM: A CASE REPORT.
CYP24A1 is an enzyme that inactivates vitamin D and encodes vitamin D 24-hydroxylase. Mutations in this enzyme have been linked with idiopathic infantile hypercalcemia, nephrolithiasis, and nephrocalcinosis. Genetic testing for this mutation should be considered in the presence of calciuria, elevated serum calcium, elevated 1,25- dihydroxyvitamin D, and suppressed parathyroid hormone. ⋯ Genetic testing excluded suspected Dent's disease but confirmed heterozygous missense variant CYP24A1 c.469C>T, p.(Arg157Trp) classified as polymorphism. He was treated with hydrochlorothiazide and potassium citrate. Children presenting with hypercalcemia, hypercalciuria and nephrolithiasis should be tested because of the importance of recognition, genetic diagnosis and proper treatment of CYP24A1 mutations that can present with a wide range of phenotypic presentations, from asymptomatic to chronic renal disease.

CLINICAL AND MICROBIOLOGICAL ASSESSMENT OF NON-SURGICAL TREATMENT OF CHRONIC PERIODONTITIS IN CONTROLLED AND UNCONTROLLED TYPE 2 DIABETIC PATIENTS.
Chronic periodontitis is a common complication in diabetes. The aim of this study was to evaluate some clinical and microbiological parameters in controlled and uncontrolled type 2 diabetes mellitus (type 2 DM) patients compared to non-diabetic (NDM) individuals, as well as to assess the effect of non-surgical periodontal therapy on these parameters. The study was performed in 61 type 2 DM patients with periodontitis (group 1A: 29 patients having achieved good metabolic control, HbA1c <7%; group 1B: 32 patients with poor metabolic control, HbA1c ≥7%), and 31 NDM individuals suffering from periodontitis. ⋯ The results recorded on the majority of measured parameters indicated that differences in treatment success achieved in the three treatment groups were not statistically significant (∆PI p=0.646; ∆GI p=0.303; and ∆CAL p=0.233). Likewise, comparison of the effectiveness in microorganism reduction revealed no significant differences between DM groups and NDM patients. Therefore, study results supported the hypothesis that periodontal therapy outcome was unaffected by the level of glycemic control in patients with diabetes.

MORPHOLOGICAL TRAITS OF HEPATIC PARENCHYMAL TISSUE REPAIR FOLLOWING EXPERIMENTAL INJURY.
The aim of the study was to investigate morphological traits of hepatic parenchymal tissue repair in response to injury using the conventional technique (closure) and an innovation method (such as hemostatic medication swab packing and modified batching). The experimental study was carried out on laboratory rats of the Winzar breed using light microscopy, standard stains for micropreparations, and morphometry. ⋯ Morphometric studies showed a significant decrease (p<0.001) in almost all indicators of the size of cells and nuclei both near necrosis and distant from it on day 28 of the experiment in the experimental group in comparison to the control group. The results obtained pointed to more intense repair processes when applying the innovation method.
