Twenty years of the International Society for Pediatric and Adolescent Diabetes Science Schools programs: Assessment of their impact on the participants' personal careers and networking development.

OBJECTIVE: The following report describes the evaluation of the ISPAD Science School for Physicians (ISSP) and for Healthcare Professionals (ISSHP) in terms of their efficiency and success. METHODS: All past attendees from 2000-2019 ISSP and 2004-2019 ISSHP programs were invited to respond to an online survey to assess perceived outcomes of the programs on career development, scientific enhancement, scientific networking, and social opportunities. RESULTS: One-third of the past ISSP (129/428), and approximately 43% of the past ISSHP attendees (105/245) responded to the surveys. Most of ISSP attendees reported that the programs supported their career (82%) by helping to achieve a research position (59%), being engaged with diabetes care (68%) or research (63%) or starting a research fellowship (59%). Responders indicated that ISSP was effective in increasing interest in diabetes research (87%) and enhancing the number (66%) and quality (83%) of scientific productions, and promotion of international collaborations (86%). After the ISSP, 34% of responders received research grants. From the first round of the ISSHP survey (2004-2013), responders reported have improved knowledge (60%), gained more confidence in research (69%), undertaken a research project (63%), and achieved a higher academic degree (27%). From the second round (2014-2019), participants indicated that the program was valuable/useful in workplace (94%) through understanding (89%) and conducting (68%) research and establishing communication from other participants (64%) or from faculty (42%). After the ISSHP, 17% had received awards. CONCLUSIONS: From the participants' viewpoint, both programs were effective in improving engagement with diabetes research, supporting career opportunities, increasing scientific skills, and enhancing networking and research activities.

Clinical characteristics, outcome, and predictors of neurological sequelae of persistent congenital hyperinsulinism: A single tertiary center experience.

AIM: Congenital hyperinsulinism (CHI) is a heterogeneous disease with variable genetic etiology, histopathology, and clinical phenotype. This study aims to describe the clinical characteristics of persistent CHI and evaluate long-term neurological outcome and its risk factors in a cohort of Egyptian children. METHODS: Clinical, genetic, and biochemical data of 42 patients with CHI were collected. Patients were invited for neurological assessment, electroencephalogram, and magnetic resonance imaging of the brain. RESULTS: ABCC8 mutation was found in (61%) of cases who underwent genetic testing (17/28). Five cases with homozygous biparental ABCC8 mutation responded to combined diazoxide and octreotide without needing surgery. Seven out of twenty-one patients who had pancreatectomy (33%) developed diabetes after a median period of 4.8 (range:1-10) years following surgery. Fifty-five percent of our patients had neurodevelopmental impairment at follow-up. Logistic regression analysis has shown that delayed referral to tertiary centre for more than 8 days, delayed diagnosis of CHI for more than 14 days and hospital admission for more than 30 days, are significant predictors of unfavorable neurological sequelae in CHI; (OR = 12.7 [2.56], p = 0.001), (OR = 12.7 [2.9-56], p = 0.001), and (OR = 3.8 [0.14.5], p = 0.043), respectively. CONCLUSIONS: ABCC8 mutation was the commonest genetic mutation underlying CHI in this study group. CHI cases with biparental homozygous ABCC8 mutation may show response to combined octreotide and diazoxide therapy. More than half of our patients had neurodevelopmental impairment at follow-up. Delayed referral to expert centre, delayed diagnosis and longer hospital stay are significant predictors of neurological disability in CHI cases.

Prepubertal gynecomastia is not always idiopathic: case series and review of the literature.

Although pubertal gynecomastia is a common clinical presentation of adolescent males, prepubertal gynecomastia is uncommon and mostly idiopathic. However, pathological causes of prepubescent gynecomastia are encountered in clinical practice. This manuscript carries an important message to general pediatricians, to care about exclusion of pathological causes for every patient of prepubertal gynecomastia. We present four different patients with pathological gynecomastia. One of them revealed to be secondary to Sertoli cell tumor, while the second patient describes trauma as a rare cause of prepubertal true gynecomastia. To the best of our knowledge, this is the first time to report occupational trauma as a cause of true gynecomastia as confirmed by pathological specimen, in a prepubertal boy. The third patient presented with retro-areolar mass and bloody nipple discharge secondary to mammary duct ectasia and had favorable self-limited course. Hyperprolactinemia secondary to neglected congenital hypothyroidism was the cause beyond gynecomastia in the fourth patient and this cause has been reported only once in the literature.Conclusion: Despite being rare, pathological causes of prepubertal gynecomastia are encountered in clinical practice, and full investigations including breast and testicular ultrasound are needed to exclude any pathology before diagnosing idiopathic gynecomastia. Repeated friction of the breast can lead to true gynecomastia not only to pseudogynecomastia as previously known. What is Known: • It has been reported that trauma can cause pseudogynecomastia due to hematoma or fat necrosis. • Prepubertal gynecomastia is mostly idiopathic. What is New: • Long-term breast trauma can cause true gynecomastia (adenosis). • Although being mostly idiopathic, pathological causes of prepubertal gynecomastia must be ruled out.

Pediatric Nurses' Knowledge of and Self-Efficacy in Breastfeeding Counseling.

OBJECTIVE: Sound breastfeeding (BF) knowledge among health professionals is vital for proper institutional support of BF mothers. This study aims to measure both BF knowledge and self-efficacy (SE) of pediatric nurses in supporting BF and to determine their associated factors. STUDY DESIGN: A cross-sectional study was conducted in Mansoura University Children's Hospital and Mansoura New General Hospital during the period from January to March 2017. A total of 186 nurses completed a predesigned self-administered questionnaire developed by the investigators to measure BF knowledge and SE in BF counseling. RESULTS: The overall total means of BF knowledge and SE scores were 26.8 (6.4) and 3.8 (0.6), respectively. Linear regression showed that having bachelor education, working in neonatal department, having a child (aged 2-5 years) were significant independent predictors of BF knowledge score (R 2 = 0.448, p ≤ 0.001), while BF knowledge score is the only significant independent predictor of SE in BF counseling (R 2= 0.36, p ≤ 0.001). CONCLUSION: Higher pregraduation education, working in neonatal department, having children aged 2 to 5 years are independent predictors of BF knowledge. Improving BF knowledge may improve nurses' SE in supporting BF.

The potential Association of Bisphenol A exposure and type 1 diabetes mellitus among Dakahlia Governorate's children sample, Egypt.

Background: Bisphenol A (BPA) is an endocrine disrupter affecting glucose homeostasis. Objectives: This study aimed to investigate BPA's relationship with Type 1 Diabetes Mellitus (T1DM) in Dakahlia Governorate's children, in Egypt. Subjects materials and methods: The study had two parts: clinical and experimental. Clinical Study was conducted on 200 children, equally divided into control and T1DM groups. They underwent: demographic data, height, weight, body mass index, glycosylated HbA1C, random blood glucose, and urinary BPA measurements. Experimental Study was conducted on 60 adult albino rats. Rats were randomly divided into three equal groups: control group: received 0.5 mL of pure olive oil, group 1: received 20 mg/kg/day BPA, and group 2: received 100 mg/kg/day BPA orally for 6 weeks. Fasting and two hours postprandial glucose levels were measured at the beginning and end of the study. Histopathological examination and imaging study of the pancreas were done. Results: In clinical study: HbA1C and random blood glucose levels in diabetic children showed a significant increase compared to control. Children in control group showed controlled HbA1C, while the T1DM group showed 86% with poor diabetic control. There was a significant increase in BPA level in the T1DM group compared to the control. Rats that received BPA showed a marked increase in fasting and two hours postprandial glucose levels, histopathological changes in the pancreas with more changes determined in the high dose group, and a significant decrease in the islets of Langerhans diameters with group 2 more affected. Conclusion: So, BPA exposure could be considered a risk factor for T1DM in children.

The Pattern of Antimicrobial Prescription at a Tertiary Health Center in Egypt: A Point Survey and Implications.

Background: The misuse of antimicrobials has major consequences, particularly antimicrobial resistance (AMR) and antimicrobials' related adverse effects. So, the WHO proposed antimicrobial surveillance to improve antimicrobials use. This point prevalence survey (PPS) was conducted to illustrate the prevalence of antimicrobial use at Mansoura University hospitals (MUH), Egypt. Methods: The survey process used was adapted from the European survey of antimicrobial resistance with modifications. The survey was conducted from 8 AM to 8 PM daily within 2 weeks. Results: A total of 300 patients received antimicrobials and the prevalence rate of antimicrobial prescription was 79.15%. The major indications of antimicrobials were surgical prophylaxis followed by the treatment of community-acquired infection. The most commonly prescribed initial antimicrobial group was Aminopenicillin ± ß-lactamase inhibitors. Although the purpose for antimicrobial administration was recorded in all cases, the stop/review history was recorded only in 19.6% and local guidelines were not available for 77.6% of antimicrobial prescriptions. The use of combined antimicrobials was common (46.6%), particularly in orthopedic and cardiothoracic surgery. Conclusion: The prevalence of antimicrobial prescription at MUH was high which requires serious actions including reviewing the antimicrobial indication, implementing local prescription guidelines, initiating an antimicrobial stewardship program (ASP), and optimizing infection control measures.

Epicardial and Perihepatic Fat as Cardiometabolic Risk Predictors in Girls with Turner Syndrome: A Cardiac Magnetic Resonance Study

Objective: Turner syndrome (TS) patients are at high risk of cardiometabolic disorders. Cardiometabolic risk factors are more commonly related to visceral rather than total body adiposity. Adipocytokines have been explored as a potential link between obesity and obesity-related cardiometabolic dysfunction. This study explored the validity of epicardial fat-thickness (EFT) and perihepatic fat-thickness (PHFT) measurement as cardiometabolic-risk predictors in TS-girls in relation to standard obesity-indices and metabolic syndrome (MetS) components. Methods: Forty-six TS girls and twenty-five controls (10-16 years) were subdivided into two age-groups (10 to less than 13 and 13-16). Participants were assessed for body mass index (BMI) Z-scores, waist circumference (WC), total-fat mass (FM) and trunk-FM by bioimpedance-technique, EFT and PHFT by cardiovascular magnetic resonance, lipid-profile, homeostasis model assessment of insulin resistance (HOMA-IR), and serum chemerin. MetS was defined according to International Diabetes Federation criteria. Results: Overweight/obesity and MetS were detected in 45.7% and 37% of TS-girls respectively. BMI Z-score, WC, total-FM, trunk-FM, EFT and PHFT values were significantly higher in TS-age groups compared to age-matched control groups, being more pronounced in the older group when TS-girls had been exposed to estrogen. Dyslipidemia, higher HOMA-IR, chemerin, EFT and PHFT values were observed in lean-Turner compared to BMI-Z-matched controls. EFT and PHFT were significantly correlated with chemerin and several components of MetS. EFT at a cut-off-value of 6.20 mm (area under the curve=0.814) can predict MetS in TS-girls. Conclusion: TS-girls displayed an adverse cardiometabolic profile during late childhood and adolescence. EFT and PHFT are emerging cardiometabolic risk predictors in TS-patients. Excess EFT rather than total body adiposity may contribute to altered metabolic profile among lean-Turner patients.

Genetic and clinical heterogeneity of permanent neonatal diabetes mellitus: a single tertiary centre experience.

AIMS: Neonatal diabetes mellitus (NDM) is a rare disease where diabetes presents during the first six months of life. There are two types of this disorder: permanent neonatal diabetes (PNDM) and transient neonatal diabetes mellitus (TNDM). PNDM occurs due to mutations in genes involved in either beta-cell survival, insulin regulation, and secretion. This study aims to define the genetic aetiology and clinical phenotypes of PNDM in a large Egyptian cohort from a single centre. METHODS: Patients with PNDM who were diagnosed, treated, or referred for follow-up between January 2002 and January 2021 were identified and clinically phenotyped. All patients were tested for mutations in EIF2AK3, KCNJ11, ABCC8, INS, FOXP3, GATA4, GATA6, GCK, GLIS3, HNF1B, IER3IP1, PDX1, PTF1A, NEUROD1, NEUROG3, NKX2-2, RFX6, SLC2A2, SLC19A2, STAT3, WFS1, ZFP57 using targeted next-generation sequencing (NGS) panel. INSR gene mutation was tested in one patient who showed clinical features of insulin resistance. RESULTS: Twenty-nine patients from twenty-six families were diagnosed with PNDM. Pathogenic variants were identified in 17/29 patients (59%). EIF2AK3, INS, and KATP channel mutations were the commonest causes with frequency of 17%, 17%, and 14%, respectively. Patients with ABBC8 and KCNJ11 mutations were successfully shifted to sulfonylureas (SU). Paired data of glycosylated haemoglobin before and after SU transfer showed improved glycaemic control; 9.6% versus 7.1%, P = 0.041. CONCLUSIONS: PNDM is a heterogenous disease with variable genotypes and clinical phenotypes among Egyptian patients. EIF2AK3, INS, ABCC8, and KCNJ11 mutations were the commonest causes of PNDM in the study cohort. All patients with KATP channel mutations were effectively treated with glyburide, reflecting the fact that genetic testing for patients with NDM is not only important for diagnosis but also for treatment plan and prognosis.

Airway Inflammatory Biomarker: Could It Tailor the Right Medications for the Right Asthmatic Patient?

Asthma is a heterogeneous disease, in which asthmatic patients present with different clinical phenotypes, variable endotypes, and different response to asthma medicines. Thus, we are faced with an asthma paradox; asthma is diagnosed subjectively by clinical history and treated with biologically active drugs. To solve this paradox, we need objective airway biomarkers to tailor the proper medications to the proper patient. Biomarkers should have one or more of the following characteristics:1) A biomarker that could differentiate poor symptoms perceivers from over perceivers, 2) A biomarker that could predict disease activity and hence disease outcome, 3) A biomarker that could clarify responders from non-responders asthma phenotypes, and finally 4) A biomarker that could characterize different clinical asthma phenotypes. In conclusion, we have conducted a review of literature trying to apply those four parameters to different airway inflammatory biomarkers. We found that FeNO fulfilled the four proposed clinical parameters of airway inflammatory biomarkers whereas; serum periostin was the single best systemic biomarker of airway luminal and tissue eosinophilia in severe uncontrolled TH2 asthma phenotype. Thus, this may be considered a trial towards tailoring the proper medication to the proper patient. However, application of biomarkers in clinical practice requires easier and cheaper techniques together with standardized methods for sample collection and analysis.

Clinical asthma phenotyping: A trial for bridging gaps in asthma management.

Asthma is a common disease affecting millions of people worldwide and exerting an enormous strain on health resources in many countries. Evidence is increasing that asthma is unlikely to be a single disease but rather a series of complex, overlapping individual diseases or phenotypes, each defined by its unique interaction between genetic and environmental factors. Asthma phenotypes were initially focused on combinations of clinical characteristics, but they are now evolving to link pathophysiological mechanism to subtypes of asthma. Better characterization of those phenotypes is expected to be most useful for allocating asthma therapies. This article reviews different published researches in terms of unbiased approaches to phenotype asthma and emphasizes how the phenotyping exercise is an important step towards proper asthma treatment. It is structured into three sections; the heterogeneity of asthma, the impact of asthma heterogeneity on asthma management and different trials for phenotyping asthma.

Lupus nephritis in Egyptian children: a 16-year experience.

We retrospectively evaluated the clinical features, histo-pathological patterns, treatment modalities, and outcome of children and adolescents with lupus nephritis (LN), followed-up in Lupus Clinic, Pediatric Nephrology Unit, Mansoura University Children's Hospital between January 1997 and December 2012. Out of 194 patients diagnosed with systemic lupus erythematosus (SLE), LN was reported in 136 (70 %) patient, they were 27 males (20 %) and 109 females (80 %). The mean age at presentation was 12.5 ± 2.9 years, the mean duration of follow up was 4.1 years (range 2 months-12 years). Hematuria was present in 79 patients (58 %), proteinuria in 126 (92.6 %), 38 of them were in nephrotic range, while renal impairment was documented in 20 patients (15 %). Renal biopsy was done in 132 patients; diagnosis of class II, III, IV, V were 23, 25, 39, and 2 % respectively. Second renal biopsy was indicated in 58 patients (insufficient first biopsy 2, follow up in 45, lupus flare in 8, no response to therapy in 3 patients), while the third one was needed in only eight patients. Steroids were the commonest initial medications; used in 128 patients (63 alone and 65 with others) and cyclophosphamide was used in 64 patients. At the last follow-up visit; 19 % of patients lost follow-up, 45 % had complete remission, 21 % still had active disease, 1 % had end-stage renal disease, and 11 % died. In conclusion, in Egypt, childhood SLE is associated with frequent and severe nephritis at presentation, and this may be attributed to genetic, ethnic, or environmental factors.

Does decline of lung function in wheezy infants justify the early start of controller medications?

OBJECTIVE: To compare lung function in wheezy infants, with risk factors of asthma and with some immunological parameters which may be useful as predictors of subsequent asthma. METHODS: The data of 241 infants aged 5­36 mo, with recurrent wheeze (≥3 episodes of physician confirmed wheeze) prior to receiving inhaled corticosteroids or anti-leukotrine agents was retrospectively analyzed. They were subdivided into 2 subgroups; those with asthma risk factors (132 patients) and those without (109 patients) Also, 67 healthy, age and sex matched children without recurrent wheezes were taken as control group. Total serum IgE, eosinophilic percentage, tPTEF/tE (time to peak expiratory flow to total expiratory time), total respiratory system compliance (Crs) and resistance of the respiratory system (Rrs) was done for patients and control groups. RESULTS: Wheezy infants had a significantly higher eosinophilic percentage and total serum IgE as well as a significantly lower pulmonary function parameters when compared to healthy controls. Wheezy infants with positive family history of asthma and those who had not been breast fed showed significant reduction in the mean values of tPTEF/tE and increased both eosinophilic percentage and total serum IgE. Crs was significantly decreased in wheezy infants with positive seasonal variations and those who had increased both eosinophilic percentage and total serum IgE. Rrs showed significant increase in wheezy infants with positive family history of atopy and those who had increased eosinophilic percentage and increased total serum IgE. CONCLUSIONS: Lung function, eosinophilic percentage, total serum IgE and asthma risk factors could be used as predictors for ongoing wheeze in this subset of children.
