Problematic Eating Behaviour in Turkish Children Aged 12-72 Months: Characteristics of Mothers and Children

Objective: The aim of this study was to determine prevalence of problematic eating behaviour (PEG), associated risk factors, feeding practices including place of meal, variety of diet, and habits of consuming junk food, the mothers' perception of the child growth status in comparison to his/her peers, and the effects on anthropometric measurements. Methods: This study was carried out among children aged 12-72 months who attended the outpatient clinic in the Ihsan Dogramaci Children's Hospital between February-June 2007. Three hundred and thirty-one mothers of children were asked to complete an extensive questionnaire covering socio-demographic characteristics and their child's general eating behaviour and feeding practices at mealtimes. Children with PEB were identified based on their mothers' statements. Results: Three hundred and thirty-one cases were 3.32 +/- 1.39 years old. One hundred thirty-five mothers reported having a child with PEB. The mothers described the children's problematic behaviour as: need to walk around with the child during mealtime (45.6%), watching TV during meals (41.9%), picky or fussy eating (39%), vomiting and/or retching (25.7%), retaining food in the mouth for a long time (20.6%), and not eating solid foods (11.8%). In children who had ate neither meat nor vegetables and fruits, took cod-liver oil-containing supplement during the course of the study, and had taken iron supplements in the first year of life, PEB was more frequent than in others. The mean z scores of weight for age (WAZ) were significantly lower in cases with PEB than without PEB. Discussion: Counselling and supporting of the mother/caregiver could alleviate the effect of inappropriate solutions taken by families. Insistence on composing of the diet variety including especially vegetables, fruits and meat may be promoted by provision of alternative cooking/presentation samples to mothers of children who refuse some foods. Pediatricians should be alerted that lower WAZ values may be a warning indicating a problem which may cause stagnated growth in children with PEB.Wo

Report of the first case of precocious puberty in Rett syndrome

Rett syndrome is an X-linked dominant disorder frequently caused by the mutations in the methyl-CpG-binding protein 2 gene (MECP2). Its prevalence in the population is 1/15,000-20,000. Patients with Rett syndrome present apparently normal psychomotor developments during the first 6-18 months of life. Subsequently, they show a short period of developmental stagnation followed by a rapid regression in language and motor development. Precocious puberty is characterized by premature breast and pubic hair development, and advanced bone age development at 8 years of age. We present a case of Rett syndrome and precocious puberty in a 6-year-old girl. At the age of 6, the first signs of precocious puberty appeared (Tanner stage 3). Laboratory measurements were detected as follows: luteinizing hormone (LH), 0.2 mIU/mL; follicle-stimulating hormone (FSH), 1.1 mIU/mL; estradiol, 36 pg/mL; bone age, 9 years. The response to luteinizing hormone releasing hormone (gonadotropin-releasing hormone stimulation test) was characteristic for true precocious puberty (LH, 32 mIU/mL; FSH, 26 mIU/mL). This is the first reported case of precocious puberty related to Rett syndrome

Diagnostic Value of Bilateral Petrosal Sinus Sampling in Children with Cushing Disease: A Multi-center Study

Objective: Although the sensitivity and specificity of bilateral inferior petrosal sinus sampling (BIPSS) were shown to be quite high in adult patients, pediatric studies are limited in number and have conflicting results, since BIPSS is much less commonly performed in children. The aim of this study was to assess the role of BIPSS in the detection and accuracy of lateralization of pituitary adenomas in pediatric patients with Cushing disease (CD) and its possible advantage over other diagnostic methods. Methods: This was a multicenter, nationwide, web-based study. The diagnostic value of BIPSS in 16 patients, aged between four and 16.5 years with a confirmed diagnosis of CD, was evaluated retrospectively. The sensitivity and specificity of BIPSS and magnetic resonance imaging (MRI) were calculated, and compared statistically. Results: Standard tests, except for morning cortisol level, were effective in proving the presence of Cushing syndrome. While MRI findings were consistent with microadenoma in eight cases (50%), CD presence and lateralization was successfully predicted in 14 of 16 patients using BIPSS. BIPSS compared with MRI examination was significantly more accurate, both in pre-stimulation and post -stimulation results (p=0.047 and p=0.041, respectively). BIPSS showed a significantly higher sensitivity (92.8%) than MRI in detecting the pituitary source of adrenocorticotropic hormone secretion. Conclusion: These results suggest that BIPSS is superior to MRI for diagnostic work-up to confirm the diagnosis of CD. Moreover, in line with previous studies, BIPSS was shown to provide better information about adenoma location, which is vital for possible surgical intervention
