The frequency of and factors affecting functional gastrointestinal disorders in infants that presented to tertiary care hospitals.

This study aimed to determine the prevalence of infantile functional gastrointestinal disorders (FGIDs) based on Rome IV diagnostic criteria, and to determine the associated patient demographic and nutritional characteristics. A total of 2383 infants aged 1-12 months which were evaluated by 28 general pediatricians and pediatric gastroenterologists on the same day at nine tertiary care hospitals around Istanbul, Turkey, between November 2017 and March 2018, were included in the study. Patients included consulted the pediatric outpatient clinics because of any complaints, but not for vaccines and/or routine well child follow-ups as this is not part of the activities in the tertiary care hospitals. The patients were diagnosed with FGIDs based on Rome IV diagnostic criteria. The patients were divided into a FGID group and non-FGID group, and anthropometric measurements, physical examination findings, nutritional status, risk factors, and symptoms related to FGIDs were evaluated using questionnaires. Among the 2383 infants included, 837 (35.1%) had ≥1 FGIDs, of which 260 (31%) had already presented to hospital with symptoms of FGIDs and 577 (69%) presented to hospital with other symptoms, but were diagnosed with FGIDs by a pediatrician. Infant colic (19.2%), infant regurgitation (13.4%), and infant dyschezia (9.8%) were the most common FGIDs. One FGID was present in 76%, and ≥2 FGIDs were diagnosed in 24%. The frequency of early supplementary feeding was higher in the infants in the FGID group aged ≤6 months than in the non-FGID group (P = 0.039).Conclusion: FGIDs occur quite common in infants. Since early diversification was associated with the presence of FGIDs, nutritional guidance and intervention should be part of the first-line treatment. Only 31% of the infants diagnosed with a FGID were presented because of symptoms indicating a FGID. What is Known: • The functional gastrointestinal disorders (FGIDs) are a very common disorder and affect almost half of all infants. • In infants, the frequency of FGIDs increases with mistakes made in feeding. When FGIDs are diagnosed in infants, nutritional support should be the first-line treatment. What is New: • This study shows that only a third of children presented to hospital because of the symptoms of FGIDs, but pediatricians were able to make the diagnosis in suspected infants after appropriate evaluation. • The early starting of complementary feeding (<6 months) is a risk factor for the development of FGIDs.

Cases of inborn errors of metabolism diagnosed in children with autism.

Background and purpose: Autism spectrum disorder is a neurodevelopmental disorder with a heterogeneous presentation, the etiology of which is not clearly elucidated. In recent years, comorbidity has become more evident with the increase in the frequency of autism and diagnostic possibilities of inborn errors of metabolism. Methods: One hundred and seventy-nine patients with diagnosis of autism spectrum disorder who presented to the Pediatric Metabolism outpatient clinic between 01/September/2018-29/February/2020 constituted the study population. The personal information, routine and specific metabolic tests of the patients were analyzed retrospectively. Results: Out of the 3261 patients who presented to our outpatient clinic, 179 (5.48%) were diagnosed with autism spectrum disorder and were included in the study. As a result of specific metabolic examinations performed, 6 (3.3%) patients were diagnosed with inborn errors of metabolism. Two of our patients were diagnosed with classical phenylketonuria, two with classical homocystinuria, one with mucopolysaccharidosis type 3D (Sanfilippo syndrome) and one with 3-methylchrotonyl Co-A carboxylase deficiency. Conclusion: Inborn errors of metabolism may rarely present with autism spectrum disorder symptoms. Careful evaluation of the history, physical examination and additional findings in patients diagnosed with autism spectrum disorder will guide the clinician in the decision-making process and chose the appropriate specific metabolic investigation. An underlying inborn errors of metabolism may be a treatable cause of autism.

Macrocephaly diagnosed during well child visits.

BACKGROUND: The measurement of head circumference (HC) provides valuable anthropometric data for a child's growth during well child visits. There are few studies on the characteristics of macrocephaly (MC) diagnosed during well child visits. The aim of this study was to identify the characteristics of children with MC diagnosed during the well-child visits. METHODS: This descriptive clinical study was carried out in the well child unit of a medical faculty hospital. The health records of all children who were followed up between 2004 and 2014 were reviewed. The records of children with the diagnosis of MC were evaluated. All children with MC had cranial ultrasonography, measurement of parental HC, and biochemistry. The HC measurements were carried out until 3 years of age in the unit. RESULTS: Ninety of 9,758 children (0.9%) had the diagnosis of MC. Of these children, 61% were male. Mean age at diagnosis was 2.7 months. The majority of children (63.3%) had familial MC. The other leading findings were isolated MC and hydrocephalus: two of eight children with hydrocephalus had delayed neuromotor development. CONCLUSION: MC was not rare in the present well child unit population. The evaluation of parental HC and cranial ultrasonography might be important for the differential diagnosis.

Assesment of obesogenic factors in school-age children.

BACKGROUND: The prevalence of obesity in childhood is increasing all over the world and the World Health Organization (WHO) regards obesity as one of the most important public health problems. The aim of our study was to investigate the changes in body mass index (BMI) in children between 6 and 11 years of age and to evaluate the factors affecting this change in two different schools. METHODS: We conducted a cross-sectional epidemiological study between January and March 2016 in two different schools. School age children from two different ages (6 and 11 years) participated in the study. Children`s sociodemographic characteristics and daily habits were evaluated by a questionnaire. Weight, height, body fat ratio were measured. RESULTS: Of all 495 students, 270 were in the 6-year old group. According to BMI classification 21.2% of students were overweight and 14.5% obese. From 6 to 11 years of age percentages of overweight and obese students increased slightly (1%). The mean daily screen time was high among overweight and obese students (p < 0.05). The obesity rate (15.9%) was higher in public school, than in private school (6%). There was an obesogenic environment in the public school; sport facilities were limited, there was a canteen selling junk food and fizzy drink, but there was no free drinking water. Screen times of 11 year-old students were longer, and regular breakfast rates were lower than those of 6 year-old group (p < 0.05). CONCLUSIONS: In our study prevalence of obesity was 14.5%, and overweight was 21.2%. According to our findings obesogenic environment seemed to be a contributing factor of obesity. Screen time should also be considered in attempts to prevent obesity.

Children with cervical lymphadenopathy: reactive or not?

BACKGROUND: This study aims to evaluate the etiology of cervical lymphadenopathies in children and to define the significance of demographic, clinical, and laboratory features in the prediction of malignancy. METHODS: Medical records of 527 patients were reviewed retrospectively between 2015 and 2019. The patients were examined in terms of demographics, clinical, radiologic, and serologic findings. A lymph node biopsy was performed in selected patients. The risk factors for malignancy were evaluated. RESULTS: Out of 527 children, 26 had neck masses mimicking lymphadenopathy; 501 had lymphadenopathy. The most common location was the anterior cervical region and the median age was 5.7 years. Thirty-nine patients had malignancy (lymphoma in 34, nasopharyngeal carcinoma in 3, leukemia in 1 and neuroblastoma in 1). The risk of malignancy was associated with older age, duration of > 4 weeks, lymph node size > 3 cm, supraclavicular location, presence of systemic symptoms, and hepatosplenomegaly (p < 0.001, p < 0.001, p < 0.001, p < 0.001, p < 0.001, p < 0.001). On laboratory evaluation, anemia, leukocytosis, and increased erythrocyte sedimentation rate were found to be associated with malignancy (p < 0.001, p=0.003, p < 0.001). CONCLUSIONS: Cervical lymphadenopathies in children are generally benign but patients with persisting cervical lymphadenopathy, adolescent age, accompanying systemic symptoms and abnormal laboratory findings should be considered for an early biopsy.

Revaccination in Pediatric Oncology Patients: One Center Experience.

OBJECTIVE: After chemotherapy, cancer survivors suffer from acquired immunological defects and become vulnerable to vaccine-preventable diseases. There are no universally approved revaccination guidelines for non-transplanted oncology patients. This study aimed to share our experience of revaccination in childhood cancer survivors to plan future vaccination schedules. MATERIALS AND METHODS: This retrospective study was conducted in a Pediatric Oncology Department of a university-affiliated hospital. Patients who were diagnosed with malignancy other than leukemia constituted the study population. Patients were directed for revaccination 6 months after the cessation of treatment. Revaccination was performed according to patients' vaccination status before chemotherapy and seronegativity. RESULTS: Of the 64 patients in the study, 44 (68.75%) were boys. The mean age at the time of diagnosis and at start of vaccination was 8.8±5.3 years and 10.6±5.1 years, respectively. Hodgkin's lymphoma was the most common diagnosis. The vaccination schedule of 7 patients was interrupted because of chemotherapy; after completing the missing vaccine doses, the serology of 2 patients was negative for at least 2 antigens. The vaccination schedule of 57 patients was completed before beginning chemotherapy and 52 of them were seronegative for at least 1 antigen. No adverse reactions or life-threatening infections were observed because of vaccinations. CONCLUSION: There are different approaches when vaccinating the oncology patients after chemotherapy. Watching out for the four touchstones mentioned in our study will protect the patient and do no harm. More studies are needed to constitute universal and standardized revaccination guidelines for these patients.

The relationship between body fat ratio and blood pressure in school-age children.

Hypertension (HTN) and obesity prevalences are rising in childhood and it is important to evaluate associations of these situations. The objective of this study is to investigate the relationship between HTN and body fat ratios (BFR) in children. This cross-sectional study was conducted among 134 participants who were directed to pediatric nephrology outpatient clinic with the prediagnosis of primary HTN. Weight, height, body fat ratio, blood pressure, and ambulatory blood pressure monitor (ABPM) was carried out for all the participants. Of the participants, 70 of them were diagnosed as hypertension with ABPM and included in the patient group, 64 of them had elevated office blood pressure (BP) but normotensive according to ABPM were included in the control group. Body fat ratio (BFR) levels of the patient group were higher than the control group (p < 0.05). There were significant linear correlation between night systolic blood pressure (SBP), night diastolic blood pressure (DBP), night mean arterial pressure (MAP), and BFR in the patient group (p < 0.05). There was a negative correlation between BFR and dipper (p = 0.022; p < 0.05) in the patient group. There was no correlation between BFR and blood pressures or dipper in the control group. According to our results BFR levels have significant association with HTN. According to our findings high BFR especially effects night BP, pulses, nondipping, and nighttime values can be evaluated only with ABPM. For prevention of HTN in children, caution should be given to monitor and lower BFR values.

Successful treatment of pediatric post-liver transplant Kaposi`s sarcoma with paclitaxel.

BACKGROUND: Kaposi`s sarcoma (KS) is a complication of immunosuppressive therapy for transplant recipients. Unlike adult recipients, KS in pediatric organ transplantation is quite rare. Treatment is usually withdrawal of immunosuppression; non-responders often receive chemotherapy. CASE: We have reported a child with post-liver transplant visceral KS which has progressed despite withdrawal of immunosuppressive therapy, who has been treated with Paclitaxel for three weeks. KS has regressed completely after four cycles of Paclitaxel. CONCLUSION: Paclitaxel should be considered as an effective first line treatment option for patients with posttransplant KS.

Risk Factor Assessment and a Ten-Year Experience of DDH Screening in a Well-Child Population.

AIM: Risk based screening for developmental dysplasia of the hip (DDH) with ultrasound is common. However, risk factors vary from one country to the other since data are insufficient to give clear recommendations. We aimed to evaluate the risk factors for developmental dysplasia of the hip (DDH). METHODS: In this retrospective case-control study, the health records of all children, who were followed up between 2004 and 2014 at a well-child unit, were investigated for the diagnosis of DDH in Turkey. Of 9758 children, 57 children were found to have abnormal ultrasonographic findings (according to Graf classification) and these constituted the case group. As the control group, healthy 228 children who matched the case children in birth months were selected. Two groups were compared for the risk factors. RESULTS: A total of 19516 hips of 9758 children were examined for DDH. 97 hips of 57 children were found to have abnormal ultrasonographic findings. When the two groups were compared, breech presentation, multiple pregnancy, and torticollis were identified as risk factors. The female sex was also found to have a significantly high prevalence among the children in the case group. Limited hip abduction, positive Ortolani, and Barlow signs were important clinical findings in the case group. CONCLUSION: According to our findings, breech presentation, female sex, torticollis, and multiple pregnancy were found to be the risk factors of this disorder. Infants with these risk factors should be investigated carefully for DDH.
