Introduction/Objective Benign transient hyperphosphatasemia (BTH) is a pathogenetic insufficiently clear clinical entity that is mostly seen in infants and young children. The objective of this paper is to present our experience regarding the age of occurrence, the conditions of the discovery, and the length of duration of BTH in children. Methods The study was realized on a sample of 18 children, nine boys and nine girls, aged 10–42 (21.06 ± 9.35) months with BTH. The diagnosis of BTH is based on the absence of bone and hepatobiliary diseases, and its spontaneous disappearance over the course of several months. Results One patient was in the first year, 13 in the second, three in the third, and one in the fourth. Isolated high activity of serum alkaline phosphatase, which was 2.04–21.9 (8.05 ± 5.31) times above the upper reference value for the corresponding age, in 14 cases it was found during the acute diarrhea, and in four with acute rhinopharyngitis, of which in two complicated with otitis media. The cause of diarrhea in six cases was rotavirus, in two Campylobacter, and in one adenovirus, and otitis media in one case was caused by Streptococcus pneumoniae, while in others, etiologic factors of infection were not identified. Spontaneous normalization of serum alkaline phosphatase activity was recorded between one and three months after the onset. Conclusion BTH is a harmless biochemical disorder that spontaneously subsides within three months after initial observation. It is found randomly as a routine laboratory finding most often within the treatment of acute gastrointestinal and respiratory infections. © 2020, Serbia Medical Society. All rights reserved.

Introduction/Objective The aim of this paper was to examine proportion of patients with arterial abnormalities of feet due to age and severity degree of pes metatarsus varus (PMV), and to evaluate the treatment duration and outcome. Methods The prospective longitudinal study included 240 patients with congenital PMV classified into three age groups: group < 3 months of life (Group 1), group 3–9 months (Group 2), and group 9–12 months (Group 3). Three categories of PMV were analyzed: mild/moderate/severe. Groups with arterial anomalies (Group A) and without (Group B) were analyzed. Clinical outcome was graded as: good/satisfactory/poor. Results There is statistically significant difference in distribution of children regarding age and severity degree on first visit and presence of feet arterial abnormalities (p < 0.01). For Group A, younger children had longer physical therapy, while for Group B, older children had longer duration of physical therapy. Same trend applies as severity degree of foot deformity increase. In Group A, the most frequent treatment outcome was poor (for Group 1 – 46.7%; Group 2 – 60%; Group 3 – 62%), while in Group B for Group 1 and Group 2 it was frequently good (Group 1 – 90%; Group 2 – 40%), and for Group 3 frequently satisfactory (Group 3 – 53.3%). Conclusion In children with PMV it might be advisable to perform ultrasound evaluation of arterial structure of feet, and particularly in cases were such deformity is more severe. © 2019, Serbia Medical Society.

Introduction/Objective Gilbert syndrome (GS) is the most common hereditary hyperbilirubinemia. As well as mild unconjugated hyperbilirubinemia, it is characterized by the excess of bilirubin monoglucuro-nide over diglucuronide in the bile and thus increases the risk of biliary calculosis. The aim of the study was to determine the importance of GS as a risk factor in the development of cholelithiasis in children. Methods The study included a sample of 31 children (14 male and 17 female, mean age 12.16 ± 4.11 years, range 3–16.75 years) with symptomatic cholelithiasis. The diagnosis of cholelithiasis was based on an ultrasonographic finding, and for GS the diagnosis was based on at least a double increase of unconjugated bilirubin fraction after a three-day hypocaloric diet (400 kcal per day). Results GS was confirmed in five or 16.13% of patients (three male and two female, mean age 14.71 ± 0.55 years, range 14–15.3 years). In addition to GS, in the history of the disease they all had some of the additional risk factors for the development of cholelithiasis. One of them had an identical problem as its mother, one had hereditary elliptocytosis, one had sudden weight loss, one was overweight, and one had premature birth and sepsis. Conclusion GS registers in one-sixth of children with cholelithiasis, but in none of them as the only risk factor for developing this disease. This finding suggests that GS is a risk factor for the development of cholelithiasis, but not sufficient in itself in that respect. © 2023, Serbia Medical Society. All rights reserved.

Introduction Pseudoachondroplasia (PSACH) is an autosomal dominant osteochondrodysplasia due to mutations in the gene encoding cartilage oligomeric matrix protein. It is characterized by rhizomelic dwarfism, limb and vertebral deformity, joint laxity and early onset osteoarthrosis. We present the girl with the early expressed and severe PSACH born to clinically and radiographically unaffected parents. Case Outline A 6.5-year-old girl presented with short-limbed dwarfism (body height 79.5 cm,

Background: New renal biomarkers such as neutrophil gelatinase-associated lipocalin (NGAL) and kidney injury molecule-1 (KIM-1) show promise in early diagnosis of contrast media induced acute kidney injury (CI-AKI). The purpose of our study was to compare the subclinical nephrotoxicity (a condition without changes in standard renal bio-markers) of gadolinium-based contrast media (Gd-DTPA, gadopentetate dimeglumine) and iodinated-based contrast media (iopromide) in pediatric patients with normal kidney function. Material/Methods: The first group (n=58) of patients included in the study were undergoing angiography with iopromide, and the second group (n=65) were undergoing magnetic resonance (MR) angiography/urography with Gd-DTPA admin-istration. The concentrations of NGAL and KIM-1 were measured four times in the urine (pre-contrast, then at four hours, 24 hours, and 48 hours after contrast administration), and serum NGAL was measured at 0 (base-line), 24 hours, and 48 hours after contrast exposure. Results: After 24 hours, serum NGAL increase of ³25% was noticed in 32.6% of the patients in the iopromide group and in 25.45% of the patients in the gadolinium group, with significantly higher average percent of this increase in first group (62.23% vs. 36.44%, p=0.002). In the Gd-DTPA group, we observed a statistically significant in-crease in urinary KIM-1 24 hours after the procedure. Normalized urinary KIM-1, 24 hours after contrast expo-sure, was a better predictive factor for CI-AKI than other biomarkers (AUC 0.757, cut off 214 pg/mg, sensitivi-ty 83.3%, specificity 54.2%, p=0.035). Conclusions: In children with normal renal function, exposure to iodinated-based and gadolinium-based media might lead to subclinical nephrotoxicity, which could be detected using serum NGAL and urinary KIM-1. © Med Sci Monit.

Background: Prediabetes is characterized by isolated impaired fasting glucose (IFG), isolated impaired glucose tolerance (IGT), and combined IFG/IGT. This study aimed to establish the prevalence of prediabetes and examine possible contributory factors in a cohort of obese adolescents.; Methods: In this prospective study, we recruited 85 obese patients from the Obesity Clinic at the University Children's Hospital and 17 normal weight controls. All patients were of Caucasian origin, 60 males/42 females, aged 7.4-18.3 years, with at least Tanner 2 stage of puberty.; Conclusion: Prediabetes occurrence was fairly high in our obese adolescents. Further studies should establish what would be the most appropriate screening test to diagnose these patients at risk for type 2 diabetes and initiate treatment without delay.; Results: Depending on criteria we used, insulin resistance was confirmed in 62-100% of obese patients, predominantly in the group with BMI SDS > 3. oGTT revealed isolated impaired fasting glucose (IFG) in 13.9%, impaired glucose tolerance (IGT) in 20.8% and combined IFG and IGT only in 2.8% of the obese patients. Patients in the prediabetes group were older (14±2.4 vs 12.8±2.5 p=0.04) and had higher glucose levels (p<0.001) during the whole oGTT compared to normal glucose tolerance (NGT) group. There was no difference between groups in respect to family history, BMI, lipids and fasting insulin. Insulinogenic index, WBISI and HOMA%B were significantly lower in the prediabetes group compared to the NGT group (p=0.07, 0.01 and 0.04 respectively). HbA1c level was measured in 58% of patients and was significantly higher in the prediabetes group (5.4±0.3 vs 5.7±0.4, p=0.002). © by Mirjana Kocova 2014.

Introduction/Objective The objective was to evaluate sonographic and laboratory findings as predic-tors of complicated and uncomplicated appendicitis in order to decide on further treatment options. Methods This is a retrospective cohort study of 174 pediatric patients who had laboratory tests and ultrasound done before appendectomy during a one-year period. Results were compared with the intra-operative and histopathological findings of complicated (gangrenous or perforated) or uncomplicated (phlegmonous) appendicitis and assessed by binary logistic regression with backward elimination. The initial model included eight predictors. After backward elimination four remained: periappendiceal fluid, hyperechoic periappendiceal fat, white blood cell (WBC) count and C-reactive protein (CRP). The final model included the interaction between periappendiceal fluid and hyperechoic periappendiceal fat. Diagnostic performance of each parameter was presented with sensitivity and specificity. Results Out of all patients, 86 had uncomplicated and 88 had complicated appendicitis (37 gangrenous, and 51 perforated). In the final model three predictors were significantly associated with complicated appendicitis: interaction between periappendiceal fluid and hyperechoic periappendiceal fat, WBC count > 11 × 109 /l, and CRP > 100 mg/l. Inclusion of interaction between periappendiceal fluid and hyper-echoic periappendiceal fat excluded them as individual predictors. The maximum outside appendiceal diameter of more than 6 mm had the highest sensitivity (93.2%), while wall thickness > 3 mm was the most specific (95.2%). Conclusion Using periappendiceal fluid and hyperechoic periappendiceal fat as sonographic predictors and WBC and CRP as laboratory predictors can differentiate uncomplicated from complicated appendicitis in children and help a physician decide on antibiotic or surgical treatment. © 2024, Serbia Medical Society.

Introduction Extra-hepatic portal vein obstruction (EHPVO) is one of the most often causes of portal hypertension in children.; Objective Establishing the importance of shunt surgery in combination with partial spleen resection in selected pediatric patients with EHPVO, enormous splenomegaly and severe hypersplenism.; Methods Distal splenorenal shunt (DSRS) with partial spleen resection was performed in 22 children age from 2 to 17 years with EHPVO. Indications for surgery were pain and abdominal discomfort caused by spleen enlargement, as well as symptomatic hypersplenism with leucopenia, thrombocytopenia and anemia. The partial spleen resection was performed by ligation of blood vessels to caudal two thirds of the spleen. After ischemic parenchymal demarcation transection with electrocautery LigaSure was performed with preservation of 20-30% of spleen tissue, and then Warren DSRS was created. Platelet and leucocytes counts and liver function tests were obtained before, one month and one year after surgery. Growth was assessed with SD scores (Z scores) for height, weight and body mass index at the time of surgery and one year later.; Results In all patients postoperative period was without significant complications. Platelets and leucocytes counts were normalized. Patency rate of shunts was 100%. Two significant shunts stenosis were observed and successfully treated with percutaneous angioplasty. During the follow-up period (1 to 9 years) all patients were asymptomatic, with improved quality of life and growth.; Conclusion Results of our study indicate that shunt surgery with a partial spleen resection is an effective and safe procedure for patients with enormous splenomegaly and severe hypersplenism caused by EHPVO. © 2014 Serbia Medical Society.
