Rare Inherited Coagulation Deficiencies: A Single-Center Study.

Background: Rare factor deficiency (RFD) is characterized by a deficiency of factor (F)I, FII, FV, FVII, FX, FXI, FXII, FXIII, or a combined deficiency of FV+FVIII or vitamin K-dependent factors. The prevalence of RFD ranges from 1/1,000,000 to 3,000,000. Combined deficiencies of vitamin K-related factors have been described in 30 families worldwide, and these patients can present with a wide range of clinical symptoms, from mucocutaneous bleeding to life-threatening symptoms such as central nervous system and gastrointestinal bleeding.

Brain imaging in children referred to pediatric neurology out-patients with headache.

Objective: Headaches are common in children and adolescents as well as in adults. Due to the fact that the primary medical concern for children presenting with headache complaints is the possibility of intracranial pathology, nowadays, imaging methods are frequently used in those patients.

Methods: Retrospective data analysis was performed on the records of children who attended the Pediatric Neurology Outpatient Clinic between June 01, 2018, and December 01, 2018, complaining of headaches.

Extraintestinal Manifestations in Children Diagnosed with Inflammatory Bowel Disease.

Objectives: We aimed to evaluate the frequency of extraintestinal manifestations (EIM) in children with inflammatory bowel disease (IBD) and the correlation of EIM with disease activity index, disease type and disease age.

Methods: Records of patients who were under the 18 years of age and followed up with the diagnosis of IBD were included in the study. The demographic characteristics of the patients, the age of the patients, the sex of the patients, the type of disease and the age of the disease were recorded.

Evaluation of vaccination status of health care workers for recommended vaccines and their acceptance of SARS-CoV-2 vaccines.

Introduction: Health care workers (HCWs) are disproportionately exposed to infectious diseases and play a role in nosocomial transmission, making them a key demographic for vaccination. HCW vaccination rates are not optimal in many countries; hence, compulsory vaccination policies have been implemented in some countries. Although these policies are effective and necessary under certain conditions, resolving HCWs' hesitancies and misconceptions about vaccines is crucial.

SARS-CoV-2 seropositivity among pediatric health care personnel after the first peak of the pandemic: nationwide surveillance in Turkey.

Background: Understanding SARS-CoV-2 seroprevalence among health care personnel is important to explore risk factors for transmission, develop elimination strategies and form a view on the necessity and frequency of surveillance in the future.

Methods: We enrolled 4927 health care personnel working in pediatric units at 32 hospitals from 7 different regions of Turkey in a study to determine SARS Co-V-2 seroprevalence after the first peak of the COVID-19 pandemic. A point of care serologic lateral flow rapid test kit for immunoglobulin (Ig)M/IgG was used.

The performance of shear wave elastography on evaluating liver changes in obese and overweight children.

Background: Real time shear-wave elastography (SWE) is a non-invasive imaging method which can quantitatively assess liver stiffness. Obesity and its complication are increasing with improving lifestyles in our century. We evaluated the performance of SWE for detecting liver changes (fatty liver, steatohepatitis) in obese and overweight children, in addition to this, we determined the diagnostic accuracy and clinical usefulness of SWE in non-alcoholic fatty liver disease (NAFLD).

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.

Factors Affecting Breastfeeding and Complementary Feeding Choices for Children Aged 24 to 48 Months.

Objectives: The aim of this study was to evaluate factors that affected decisions regarding breastfeeding and complementary feeding practices in children aged 24 to 48 months.

Methods: Children aged 24 to 48 months who were presented at the outpatient clinic of a single hospital over a 6-month period were included in the study. Children who were born prematurely, hospitalized in the neonatal intensive care unit, and those with a chronic disease were excluded.
