Analysis of pupillary responses in pediatric patients with vitamin D deficiency.

PURPOSE: To evaluate the effects of vitamin D deficiency on pupillary responses in the pediatric population. METHODS: The study was conducted using data from the right eyes of 52 children with vitamin D deficiency and 52 healthy children. Measurements were taken under static and dynamic conditions with automatic pupillometry. Static measurements were performed at scotopic, mesopic, and photopic light intensities. The mean pupil dilation speed was calculated by observing the changes in pupil dilation over time according to dynamic measurements. Differences between patient and control groups were analyzed for the static and dynamic measurements and the mean pupil dilation speed. RESULTS: While the two groups were similar in terms of scotopic, mesopic, the first dynamic measurements, and the pupil dilation speed data (p > 0.05), a significant difference was found in the photopic conditions (p = 0.001). The mean pupil diameter of the patient group was 4.46 ± 0.928 mm and 3.95 ± 0.556 mm in the control group under photopic conditions. CONCLUSIONS: Pediatric patients with vitamin D deficiency have significantly larger pupil diameters in photopic conditions than healthy children. These results suggest that there is an autonomic dysfunction in vitamin D deficiency in the pediatric population, especially pointing to the parasympathetic system.

Evaluation of Haematological Parameters and Uric Acid in the Diagnosis of Late Onset Neonatal Sepsis.

Introduction A number of parameters studied in a whole blood count can be helpful in the diagnosis of neonatal sepsis. The platelet/lymphocyte ratio (PLR) is a systemic inflammatory marker in early sepsis and has been used as a diagnostic indicator in cardiovascular events and cancer. Being one of the major antioxidants in human biological fluids, serum uric acid is responsible for neutralising free radicals. The red cell distribution width/platelet ratio (RPR) is a diagnostic marker in adult inflammatory diseases. The objective of our study is to investigate the relationship of late neonatal sepsis with whole blood count parameters and serum uric acid levels. Materials and methods Newborns older than postnatal three days who had clinical and laboratory findings of sepsis were included in the study. The study included 140 newborns who were divided into three groups, 53 in the culture-proven late sepsis group, 47 in the clinical sepsis group, and 40 in the healthy control group. The whole blood count parameters and serum uric acid levels were examined in both the clinical sepsis and proven sepsis patients at the time when they were diagnosed with sepsis. Results The birth week was significantly lower in the evidenced and clinical sepsis patients compared to the healthy control group. Development of late sepsis was significantly higher in the male gender than in healthy controls. Serum uric acid levels were significantly higher in proven or clinical sepsis than in healthy controls. The level of serum uric acid (3.77±1.6) in proven sepsis was significantly higher than the control group (2.83±1.1). The uric acid level had an area under the curve (AUC) 0.552-0.717, 35% sensitivity, 95% specificity, 94.6% positive predictive value (PPV), and 36.9% negative predictive value (NPV) in the diagnosis of proven and clinical late sepsis. Neutrophil/lymphocyte ratio (NLR) was significantly higher in proven sepsis than in healthy newborns and was higher in the clinical sepsis group than in the proven sepsis group (p: 0.002). While the mean eosinophil value was 618.5±472.1 in proven sepsis, it was 549.3±294.9 in the control group and there was a statistically significant difference between the two groups (p: 0.036). Conclusion In late-onset neonatal sepsis, the NLR level was higher, and the eosinophil level was lower in the clinical sepsis patients than in healthy newborns. We believe that a higher level of serum uric acid in sepsis is effective in the early diagnosis of patients who also had other clinical findings of sepsis.

Evaluating the Social Anxiety Depression Levels and Accompanying Psychosocial Problems in Children Diagnosed with Enuresis.

INTRODUCTION: This study was conducted to evaluate the accompanying psychosocial problems in enuresis as well as the social anxiety-depression levels in children diagnosed with enuresis. METHODS: This descriptive study investigating depression and social anxiety levels of children diagnosed with enuresis was carried out with 167 children who were followed up for at least six months following their enuresis diagnosis. All participating children had no other physical or mental illnesses and were aged five years or older. Data were collected using three measurement tools and evaluated using descriptive, correlational analyzes. RESULTS: In this study, 69.4% of the children diagnosed with enuresis were aged 7-12 years. 38.3% of their parents used "reward", while 37.1% preferred "punishment" as a method for toilet training their children. The children's depression and social anxiety mean scores were 21.48±7.29 and 54.58±8.84, respectively. A strong positive correlation was found between the children's mean depression and social anxiety scores (r=0.677, p<0.001). The median depression scores of children were found to be statistically significantly different according to the children's type of family, night sleep characteristics, type of enuresis, school success, and family life (p<0.05). Those with fragmented families (p=0.049), who did not sleep deeply at night (p=0.031), who slept for about 5-7 hours a day (p<0.01), and those whose school success was negatively affected by enuresis (p=0.021) and those who were exposed to negative family life (p=0.034) all obtained statistically significantly higher median depression scores. CONCLUSION: Children with enuresis had low depression and moderate social anxiety and their depression increased as their social anxiety increased. The children experienced psychosocial difficulties due to enuresis. When treating children with enuresis, it is necessary to consider both the affected child and their families through the adoption of a holistic approach, and also to evaluate the children both physically and psychosocially.

Outcomes and comparison of nasolacrimal probing for patients older than 12 months.

OBJECTIVE: In this study, we report the results of probing done in our clinic. We also want investigate role of late probing on outcome, especially in children older than 24 and 48 months. METHODS: We retrospectively evaluated records of patients who underwent probing under general anaesthesia due to congenital nasolacrimal duct obstruction between 2013 and 2017 in Nigde Ömer Halisdemir University Faculty of Medicine in Nigde, Turkey. Success rates of probing for different age groups were compared. RESULTS: 143 eyes of 123 patients were included in the study. Overall success rate was 93.7% (134 eyes out of 143). We found the success rate as 95.5 in 12-18 months age group, 93.3% in 18-24 months age group, 93.8% in the 24-48 months age group, 86.6% in the 48 months and older age group. Overall success rate in 24 months and older age group was 91.5%. The second operation was performed on seven of the nine patients where the initial surgery failed, and successful results were achieved in six patients. Success rate was 100% after the second surgery in patients older than 48 months. CONCLUSION: The success rate of probing is high in patients with congenital nasolacrimal duct obstruction from 12 to 84 months. In patients with congenital nasolacrimal duct obstruction who are older than 48 months probing is effective and should be first-choice in this age group in management of congenital nasolacrimal duct obstruction. Probing may be used even in older patients who had previous unsuccessful probing.

Risk factors of severe atopic dermatitis in childhood: single-center experience.

The aim of this study was to evaluate the risk factors of disease severity to facilitate better management of children with severe atopic dermatitis (AD). All the patients were diagnosed using Hanifin-Rajka criteria. After medical and family histories were obtained and a detailed physical examination was performed, disease severity was determined with the objective SCORing Atopic Dermatitis (SCORAD) index. Skin prick tests were performed, and percent of peripheral blood eosinophils, total serum IgE and specific IgE were measured. The median age of the 501 patients was 15 months (interquartile range [IQR]: 6-40 months), and 62.9% (315) were male. Sensitization to at least one allergen and foods was observed in 40.3% (202) and 30.9% (155) of all patients, respectively. Of the study group, 17.6% (88) had severe disease. When logistic regression analyses were performed, with adjustments, the risk factors for severe AD were determined to be eosinophilia (odds ratio [OR] 1.137, 95% confidence interval [CI] 1.062-1.217; p=0.003) and food allergen sensitization (OR: 1.937, 95%CI: 1.217-3.084; p=0.005). The patients with severe AD had sensitization to common allergens, food allergens and eosinophilia more frequently than those with mild-moderate disease (p=0.001, p=0.001 and p=0.005, respectively). Eosinophilia may predict severe disease and allergic sensitization. Further large-scale follow-up studies are needed to improve the reliability and relevance of this relation.
