Involvement of Vitamin D in Chronic Infections of the Waldeyer`s Ring in the School Aged Child.

Chronic infections of the Waldeyer`s lymphatic ring constitute a frequent pathology in school age, one of the pathogenic mechanisms involving low levels of vitamin D. In this study, we analyzed integrated the clinico-epidemiological aspects, the risk factors and the serum level of vitamin D for 51 school aged children who presented chronic inflammation in various levels of the Waldeyer`s ring. Most inflammations were present in females patients (80.4%), from the urban areas (66.6%), being localized in palatine tonsils (64.7%), in patients with deficient prophylaxis of hypovitaminosis D (68.6%) and low serum levels of vitamin D (72.5%). The results highlight the importance of maintaining a normal status of vitamin D, especially in recurrent infectious context.

The Role of Early Diagnosis of Hepatorenal Cystic (HRC) Syndrome in Children-Clinical Trial.

The hepatorenal cystic (HRC) syndrome is a heterogeneous group of severe monogenic conditions that may be detected before birth. Effective programme evaluation of children with HRC syndrome is a systematic way to identify the renal and urinary tract malformations which represent the most common cause of end-stage renal disease (ESRD). We conducted a study involving 50 patients, who were between 3 months and 16 years of age, with multiple admissions in the Nephrology Department of "Maria Sklodowska Curie" Children Emergency Hospital from Bucharest, during 6 years (April 14th 2010-October 24th 2016), to evaluate the HRC syndrome. The admission symptomatology was mainly represented by the nephrology evaluation which was essential in the management of children's polycystic kidney disease. For example, a premature infant (gestational age=32 weeks) with positive heredo-collateral history (mother and grandmother were diagnosed with polycystic kidney disease), was tested positive for cystic renal disease after the fetal morphology was performed. It was also done a genetic determination for the presence of PKD1 and PKD2 mutations which are specific to autosomal dominant polycystic kidney disease-ADPKD. However, the genetic test was negative and a postnatal nephrological evaluation was performed using renal ultrasound. The image revealed autosomal recessive polycystic kidney disease-ARPKD. This study emphasizes the importance of an early diagnosis (prenatal, neontal, postnatal) correlated with the admission symptoms and also with the genetic diagnosis (mutations of PKD1 and PKD2).
