High School, Aptitude and Achievement Tests have been utilized since 2002 in Saudi Arabia for the purpose of student selection to health sciences and medical colleges. However, longitudinal studies determining the predictive validity of these so-called cognitive tests for in-course performance is lacking. Our aim was to assess the predictive validity of Saudi health sciences and medical school pre-admission selection tools for in-course performance over a three year period and therefore we conducted a retrospective review of pre-admission (High School Test, Saudi Aptitude and Achievement tests) and in-course academic performance data (Grade Point Average, GPA) for all students enrolled in undergraduate Health Sciences Colleges and College of Medicine, 2007-2010. Correlation and linear regression analyses were performed for the whole cohort. Data are reported on 87 of 1,905 (4.6%) students who applied to Health Sciences and Medical Colleges. The results indicate that in-course GPA scores in year three were significantly positively correlated with High School (r = 0.65; p < 0.05), Aptitude (r = 0.65; p < 0.05) and Achievement (r = 0.66; p < 0.05) selection test scores. Furthermore, the High School Exam was the best predictor of achievement in year three. Regression analysis revealed that 54% of the variance in predicting academic performance is explained by the three test scores. Results confirmed our hypothesis that High School, Aptitude and Achievement tests are statistically predictive of academic performance in health sciences and medical colleges. Further longitudinal, national work is nevertheless required to determine the extent to which pre-admissions cognitive and non-cognitive tests, socio-demographic and educational process variables predict undergraduate and postgraduate achievement and performance.

In most developing countries, nutritional rickets is a major health problem. The aim of this study was to explore the magnitude of nutritional rickets among Saudi infants, and the various clinical presentations, as well as to address the possible operating risk factors behind the disease. We carried out a retrospective study at King Abdulaziz Medical City-King Fahad National Guard Hospital in Riyadh, Saudi Arabia. The records of Saudi infants under the age of 14 months over a 10-year period (between January 1990 and January 2000) were reviewed. Infor-mation collected included age, sex, clinical presentations, biochemical, radiological findings, infant nutrition, presence of other nutritional deficiencies and exposure to sunlight. There were 283 infants diagnosed with nutritional rickets due to Vitamin D deficiency (67% males) who were between 6 and 14 months of age. Among the total, 70% were exclusively breast-fed, and 23% were breast-fed until the age of 1 year. The most frequent clinical presentation was hypo-calcemic convulsions (34%) followed by chest infections (33%) and gastroenteritis (25%). In conclusion, nutritional rickets is still prevalent in Saudi Arabia with the primary etiology being vitamin D deficiency. Therefore we recommend that every infant, who is exclusively on breast-feeding, has routine supplement of vitamin D in the range of 200 IU/day (alone or as apart of multivitamin), started soon after birth until the time of weaning.

Background: Lockdown was a unique experience that affected many aspects of life, particularly during the challenge of Ramadan fasting (RF). Studying this can increase understanding of the effects of lifestyle changes on quality of life (QoL) for children with type 1 diabetes (T1D) during RF., Methods: A cross-sectional study that assessed the effect of lockdown on lifestyle and QoL on fasting children living with T1D during Ramadan in the Middle East and North Africa region (2020-2021). We compared the child (self) and parent (proxy) reports using PEDQoL v3.0 disease specific questionnaire during lockdown and non-lockdown periods, and assessed correlations with lifestyle changes using regression and gap analyses., Results: A total of 998 reports from 499 children with T1D aged 8 to 18 years (study = 276, control = 223), and their parents during RF in lockdown and non-lockdown periods. Fathers were more involved in their children's care during lockdown ( P  = .019). Patients had better compliance with treatment ( P  = .002), a reversed sleep pattern ( P  = .033), increased food intake ( P  ⩽ .001), and less exercise ( P  < .001). Children and parents perceived better QoL during lockdown ( P  ⩽.001) with no differences between their reports in "Diabetes Symptoms", "Treatment Adherence," and "Communication" domains. Self and proxy reports were different in all domains during non-lockdown ( P  = <.001-.009). In gap analysis, although not statistically significant, the gap was approximated between children's and parents' perceptions in all domains during lockdown., Conclusion: COVID-19 lockdown had a positive impact on QoL of children living with T1D during RF, possibly due to lifestyle changes and superior psychosocial family dynamics., Competing Interests: The author(s) declared no potential conflicts of interest with respect to the research, authorship, and/or publication of this article., (© The Author(s) 2023.)

Background: Congenital Adrenal Hyperplasia (CAH) is a chronic disease that requires lifelong treatment. Patients may face stigmatization, which may affect their quality of life (QoL). Therefore, we assessed the clinical characteristics and QoL of patients with CAH in the Middle East., Methods: This case-control study included patients with CAH aged >5 years from two tertiary centers (2020-2021). The patients were matched to a healthy control group and were then divided into pediatric and adult groups. Data were collected from their electronic medical records. Additionally, the EQ-5D-5L QoL questionnaire was completed by both the patients and control group to assess five domains (mobility, self-care, usual activities, pain/discomfort, and anxiety/depression)., Results: The study included 248 patients with CAH (females: 58.8%), with a family history of the condition (57.3%) and/or parental consanguinity (68.1%). The most frequently reported gene defect was CYP21A2, while the most commonly reported symptoms/signs were ambiguous genitalia and obesity. Almost all female patients had received corrective surgery. The questionnaire response rate was 86.3% (n=214/248). The CAH patient group's mean total QoL score was 85.2 compared with 99.8 in the control. Further, CAH patients had lower QoL scores in all domains compared to those in the control group (p ≤ 0.0001-0.0023). The pain/discomfort and anxiety/depression domains were affected significantly more than the other domains were, with 47.7% and 44.4% participants, respectively, p<0.0001. Additionally, obesity was found to be a predictor of reduced mobility following a logistic regression analysis (p ≤ 0.04, OR (0.18-0.98))., Conclusion: Patients with CAH reported lower QoL overall, particularly in the pain/discomfort and anxiety/depression domains. Based on this, we recommend the early involvement of psychologists in a multidisciplinary team approach, pre-marital screening, and the implementation of awareness programs for people diagnosed with CAH in communities with high consanguineous mating., Competing Interests: The authors declare that the research was conducted in the absence of any commercial or financial relationships that could be construed as a potential conflict of interest., (Copyright © 2023 Shafaay, Aldriweesh, Aljahdali, Babiker, Alomar, Alharbi, Aldalaan, Alenazi, Alangari, Alsagheir, Adriaansen, Claahsen – van der Grinten and Al Alwan.)

The objective is to assess the feasibility, barriers, expectations and motivation of health trainees in Saudi Arabia regarding medical missions. This study seeks to fill the gap in global health curricula and regulations, as well as provide guidance for trainees participating in international health electives in Saudi Arabia. This cross-sectional survey of health trainees (in medical, surgical and other allied health professions) was conducted across Saudi Arabia from March 2017 to February 2018 using a standardised survey adapted to assess expectations, barriers, awareness of available opportunities and the effect of mentorship in improving motivation toward medical missions. A total of 589 respondents completed the survey, with a response rate of 83.7%. Most respondents were under 35 years old, with an equal sex distribution. Furthermore, the respondents primarily had medical and surgical specialties training and graduated from the western region of Saudi Arabia. Health trainees who considered volunteering during training but did not have previous experience in missions acknowledged that the presence of a staff member experienced in missions in their training environment positively affected their interest in missions ( p = 0.038). The most common reasons for interest in volunteerism were to enhance one's own technical and clinical skills and help others in need. Interest in tourism and learning about new cultures are additional reasons. Only 7/589 participants had experience and expressed the barriers they faced during volunteerism. Interestingly, their colleagues who did not have a similar experience perceived almost the same barriers. A major barrier faced by experienced participants was the 'lack of elective time', compared to the 'lack of available organised opportunities' by the inexperienced group. In conclusion, coordinating health trainees' missions through a unified authoritative body would provide better opportunities, override challenges and improve their perceptions and participation in these missions., Competing Interests: The authors declare that they have no conflicts of interest., (Copyright © Sudanese Association of Pediatricians.)

Background: Post-operative pituitary insufficiency (PI) occurs in children with supra-tentorial tumors (STT) because of surgery or the mass effect of the tumor. We assessed the prevalence and clinical characteristics of STTs and predicted postoperative PI in our patients., Methods: This retrospective cohort study included children who underwent surgery for STT in two tertiary hospitals in Saudi Arabia (2009-2019). We focused on clinical, radiological, and histopathological features of STTs. We also used a linear regression model to predict post-operative PI., Results: The study included 55 children (1-18 years, mean: 9.5 ± 4.9 years, 32 [54%] females) with an initial presentation of STT that required surgery excluding recurrent episodes. The calculated period prevalence of STT was 18.2%, and the prevalence of postoperative PI was 58.2% (n = 32/55). The most common symptoms were headache and visual disturbances, and 20% patients had preoperative symptoms of PI. Baseline preoperative investigations for PI were performed in 60% of patients, and dynamic tests were conducted in only seven patients. A residual cortisol deficiency was presumed in 24 (43.7%) patients and 18 (32.7%) patients who developed central diabetes insipidus (DI) post-operatively. Overall, the brain imaging correlated well with the histopathological diagnosis (kappa = 0.48; P  < .001). Craniopharyngioma (n = 15/55, 27.3%) was the commonest STT. Predictive factors for a postoperative residual PI included age (10.9 ± 4.8 years; p-value = .027), female gender (p-value = .016 [OR = 8.31; 95% CI (1.48-46.71)], presentation with headache ( P value = .039 [OR = 9.27; 95% CI (1.12-76.72)]), and visual disturbances (p-value = .044 [OR = 5.07; 95% CI (1.04-24.61)]., Conclusion: STTs commonly occurred in our study population, and females were more prone to develop a residual PI. On-time surveillance of an intact endocrine system during the perioperative period is essential for the prediction and early management of PI., Competing Interests: The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (© 2022 Publishing services provided by Elsevier B.V. on behalf of King Faisal Specialist Hospital & Research Centre (General Organization), Saudi Arabia.)

Objective: Puberty has a significant contribution to the final height. Therefore, it is crucial to understand the normal variations in the onset and tempo of puberty in a specific population. In this study, we aimed to provide normative data on the timing of puberty and late pubertal height (LPH) in Saudi schoolboys in Riyadh., Methods: This is a cross-sectional field study (2011-2013) including Saudi schoolboys (grades 1-12; aged 6 to 19 years). Schools were chosen to represent the population from urban and rural areas in the Riyadh region. Pubertal maturity staging for gonads was assessed by measuring testicular size using a Prader orchidometer and assessing the Tanner staging of pubic hair. The marginal mean age was calculated using regression analysis., Results: We recruited 1086 schoolboys. The estimated mean age of pubertal onset at G2 was 11.8 (95% CI 11.60-12.0) years, for gonadal development at G3 was 13.2 (95% CI 12.9-13.5), G4 = 15.0 (95% CI 14.7-15.2), and G5 = 16.1 (95% CI 15.9-16.3) years, and for pubic hair stage 2 (PH2) was 12.6 (95% CI 12.4-12.9) years. The estimated time from G2/PH2 to G5/PH5 was 4.3 and 3.9 years, respectively. At the onset of puberty, the mean height was 144.7 cm and it reached 167.8 cm at G5 with a pubertal height gain of 23.1 cm., Conclusion: Our data present the norms of the timing of puberty and LPH in Saudi schoolboys. Saudi adolescent males are shorter than some European and American comparatives mainly due to shortness during childhood. However, they could have shorter LPH than Turkish, Greek, Thai, and Japanese due to a less pubertal height gain., Competing Interests: The authors declare that they have no conflict of interest., (Copyright © 2022 Ibrahim Al Alwan et al.)

Dyslipidemia is a major risk factor for atherosclerosis. Screening for dyslipidemia at an early age is essential to prevent and control its consequences. This study aimed to determine prevalence of dyslipidemia and its correlates among adolescents in Saudi Arabia. Data of 5854 adolescents aged 10-19 years from all 13 regions of Saudi Arabia were obtained from the Jeeluna study; a national cross-sectional, multistage stratified cluster sample survey. Dyslipidemia was defined based on the National Heart Lung and Blood Institute and National Cholesterol Education Program guidelines for adolescents. We found that a quarter of Saudi adolescents have dyslipidemia (males: 33.3%, females: 17.9%). Significant variation was observed by region (p < 0.001). Prevalence of abnormal Total Cholesterol was 6.7%, LDL-C 7.1%, HDL-C 12.8%, Non-HDL-C 8.3%, and Triglycerides 9.6%. Factors independently associated with dyslipidemia were male gender (OR = 2.19, 95% CI 1.78-2.70, p < 0.001), BMI (underweight OR = 0.80, 95% CI 0.69-0.94, overweight OR = 1.76, 95% CI 1.50-2.06, obese OR = 2.80, 95% CI 2.34-3.34, p < 0.001, vs. normal) and serum ferritin (high OR = 7.02, 95% CI 1.49-34.79, low OR = 0.82, 95% CI 0.67-1.01, p = 0.04 vs. normal) and ≥ 1 daily intake of carbonated beverage (OR = 1.10, 95% CI 1.00-1.20, p = 0.03 vs. no or not daily intake). Public health interventions for improving lipid profile of adolescents are urgently needed., (© 2022. The Author(s).)

Objectives: Diabetic ketoacidosis (DKA) is a life-threatening complication and a leading cause of hospitalization in patients with type 1 diabetes mellitus (T1DM). We aimed to assess the risk factors of admissions of children with DKA in a specialized children's hospital to reduce morbidity and inform appropriate prevention and intervention strategies., Methods: We conducted a retrospective review of all DKA admissions at King Abdullah Specialized Children's Hospital, Riyadh (March 2015-December 2017). Data were gathered from newly diagnosed patients with T1DM and known patients ≤ 14 years old with DKA criteria. The main variables were frequency, precipitating factors, and other characteristics of DKA admissions in both groups., Results: A total of 116/562 patients with T1DM (mean age 8.9±3.0 years) had 146 DKA episodes, of which 42/116 (36.2%) were newly diagnosed. The frequency of DKA admissions were 146/562 (26.0%), of which 42/141 (29.8%) were newly diagnosed versus 104/421 (24.7%) known T1DM patients. The majority were 10-14 years old ( p ≤ 0.001), and 77.8% were females. Missing insulin was the main cause of DKA ( p = 0.001) among known patients with T1DM. Recurrent episodes (n = 30/146, 20.5%) occurred in 15/116 patients and were more common in children ≥ 10 years of age ( p = 0.024). The mean length of stay was 2.6±2.0 days and increased with DKA severity ( p = 0.008)., Conclusions: Most DKA episodes were in patients with known T1DM and missing insulin was the leading cause of DKA. In addition to awareness campaigns to prevent DKA as an initial presentation, intervention strategies should also target high-risk groups of known patients of T1DM such as adolescents and patients with recurrent episodes., (The OMJ is Published Bimonthly and Copyrighted 2022 by the OMSB.)

In 2016 a new syndrome with postnatal short stature and low IGF1 bioavailability caused by biallelic loss-of-function mutations in the gene encoding the metalloproteinase pregnancy-associated plasma protein A2 (PAPP-A2) was described in two families. Here we report two siblings of a third family from Saudi Arabia with postnatal growth retardation and decreased IGF1 availability due to a new homozygous nonsense mutation (p.Glu886* in exon 7) in PAPPA2. The two affected males showed progressively severe short stature starting around 8 years of age, moderate microcephaly, decreased bone mineral density, and high circulating levels of total IGF1, IGFBP3, and the IGF acid-labile subunit (IGFALS), with decreased free IGF1 concentrations. Interestingly, circulating IGF2 and IGFBP5 were not increased. An increase in growth velocity and height was seen in the prepuberal patient in response to rhIGF1. These patients contribute to the confirmation of the clinical picture associated with PAPP-A2 deficiency and that the PAPPA2 gene should be studied in all patients with short stature with this characteristic phenotype. Hence, pediatric endocrinologists should measure circulating PAPP-A2 levels in the study of short stature as very low or undetectable levels of this protein can help to focus the diagnosis and treatment., (© 2021 The Authors.

Background: Children with type 1 diabetes (T1D) at different stages of development have age-specific needs, which can influence their perception of quality of life (QoL). In our study, we aimed to emphasize these age-specific needs and assess the perception of QoL in Saudi children with T1D, as well as their parents correlating QoL scores with children's glycemic control., Methods: This is a cross-sectional study in which children with T1D and their parents from 2 tertiary institutes in Saudi Arabia have answered a standard diabetes-specific QoL questionnaire (PedsQL™ 3.0 diabetes module, translated in Arabic). We also reported glycated hemoglobin (HbA1c) results for these children within a month of completing the questionnaire. The QoL total aggregate and domain scores for self (children) and proxy (parents') reports were compared and correlated with children's HbA1c., Results: A sample was 288 self and proxy reports from 144 children with T1D of 3 age groups: 5 to 7 years (7%), 8 to 12 years (49%), and 13 to 18 years (44%), and their parents. QoL differed significantly between self and proxy reports in the total aggregate and domain scores ( P -values range from .02 to <.001). The impact on QoL was significantly higher in female patients ( P  = .043). Insulin pump users had better HbA1c ( P  = .007), and HbA1c level was worse in those who intended to fast at Ramadan ( P  = .005)., Conclusion: Children with T1D at different developmental age groups perceive QoL differently than their parents. Adjusting management as per age-specific challenges could potentially improve these children's QoL and glycemic control., Competing Interests: Declaration of conflicting interests:The author(s) declared no potential conflicts of interest with respect to the research, authorship, and/or publication of this article., (© The Author(s) 2021.)

Background: Low-density lipoprotein cholesterol (LDL-C), as a modifiable risk factor for atherosclerotic cardiovascular disease, should be assessed and monitored. This study compared directly measured and Friedewald-estimated LDL-C values in children and adolescents., Methods: Blood samples were collected from 464 children and adolescents. Calculated LDL-C (CLDL-C) levels were estimated using the Friedewald formula for any triglyceride value below 4.6 mmol/L. Direct LDL-C (DLDL-C) levels were measured on an ARCHITECT c8000 Abbott Clinical Chemistry Analyzer. The differences in LDL-C were then calculated., Results: The correlation coefficients (R) between DLDL-C and CLDL-C were 0.978 (P = .148) and R = 0.970 (P = .052) for children and adolescents, respectively. Children with LDL-C values above 4.92 mmol/L had a correlation value of 0.971 (P = .419). The correlation and agreement between DLDL-C and CLDL-C in adolescents were moderate for LDL-C below 2.85 mmol/L (R = 0.806; 84.1%) and improved above 2.85 mmol/L (R = 0.978; 91.5%). In children, good correlations between DLDL-C and CLDL-C were observed for normal (<0.85 mmol/L), borderline (0.85-1.12 mmol/L), and abnormal (≥1.13 mmol/L) triglyceride levels (R = 0.9782, 0.990, and 0.951, respectively). The rates of agreement were better for normal (80.5%) and borderline (82.9%) but not abnormal (68.2%) triglyceride levels., Conclusion: We observed good agreement between DLDL-C and CLDL-C in both children and adolescents. The Friedewald formula provided an adequate estimate of LDL-C for most fasting specimens. LDL-C difference percentage can also be used as a quality indicator to check laboratory analyzer performance in healthy subjects., (© 2020 The Authors.

Thyroid hormones are essential for normal growth and development in children. Nutritional factors are closely related to thyroid dysfunction due to deviation from normal physiology of the gland. Iodine, a main constituent of thyroid hormones (T3 and T4), deficiency is one of the commonest causes of hypothyroidism in children and adults, worldwide. Other micronutrients, such as Cruciferous vegetables, Pearl Millet, Soy products and Cassava, were also attributed to cause thyroid dysfunction. Environmental factors, namely, contamination of water with goitrogens could also contribute to the aetiology of goitre in some endemic areas. Dietary advice and avoidance of excessive use of goitrogens in diet are part of guidance on nutritional safety that needs to be established, especially in the areas of endemicity., Competing Interests: The authors declare that they have no conflict of interest., (Copyright © Sudanese Association of Pediatricians.)

Medical errors are still common despite advances in technology and policies to insure patients' safety. They can be traceable as in medications or surgical errors, but may not be so in diagnostic errors that are patient, physician, or system related. This study aimed to explore whether aggressive behavior of some patients might affect physicians' clinical reasoning and decision-making. The study was conducted in a format of observation skills clinical examinations (OSCEs). It included simulating patients (SPs) and family physicians in residency training in a clinical setup. The experiment included two arms of dealing with case scenarios with "Neutral" and "Aggressive" behaviors. Explanatory variables assessed were duration of consultation, correct diagnosis, and plan of appropriate management as well as patients' satisfaction. Participants were 14 trained SPs who played the roles of aggressive and nonaggressive patients when they encountered 35 residents (18 were males) in family physicians [year 2 (R2), year 3 (R3) and year 4 (R4)]; in a total of seventy patient/doctor encounters. Compared with nonaggressive patients, aggressive patients had statistically significantly prolonged OSCE duration [mean (standard deviation) = 6.89 (1.35) and 6.11 (157) min, respectively; P = 0.031] and more patient consultation satisfaction (P <0.0001). However, no statistically significant differences were found in diagnostic accuracy (P = 0.626) and management (P = 0.621). In a stratified analysis, junior doctors had longer duration of consultation and seemed to perform better in management (higher patient satisfaction and better management outline) than their senior counterparts. Patients' aggressive behavior led to longer duration of medical consultation. Poor management plan, albeit correct diagnosis, in senior doctors may be due to disruptive clinical reasoning in disturbed stressful situation. Coping strategies should be emphasized in medical education to ensure effective clinical reasoning in patient/doctor encounters.

Our research shows that the newborns of vitamin D-deficient mothers have higher serum alkaline phosphatase (ALP) activity compared with those of vitamin D-non-deficient mothers, which is likely related to increased bone turnover rather than just being a marker for bone formation. This has a potential negative impact on fetal bone development and subsequent skeletal growth., Purpose/introduction: Low maternal serum 25-hydroxy vitamin D (25(OH)D) level during pregnancy contributes to vitamin D deficiency in infants at birth, which is associated with multiple potential adverse effects on fetal skeletal mineralization and growth. We studied the relationship between maternal 25(OH)D level and newborn serum alkaline phosphatase activity (ALP) at term., Methods: In this prospective cross-sectional hospital-based study, venous blood samples of healthy pregnant mothers were drawn to measure 25(OH)D levels within 6 h of delivery. Cord blood samples were examined for calcium, phosphorus levels, and ALP activity immediately after birth. In addition, we also recorded the newborns' anthropometric measurements., Results: Seventy-two percent (n = 108/150) of mothers in our study were vitamin D-deficient (serum 25(OH)2D < 25 nmol/l). In a multivariate logistic regression model, young maternal age (odds ratio (OR) = 0.94, 95% CI 0.88-0.99, p = 0.04) and increased weight (OR = 1.03, 95% CI 1.01-1.07, p = 0.02) as well as decreased milk intake (OR = 0.31, 95% CI 0.13-0.74, p = 0.009) were all significantly associated with maternal vitamin D deficiency. ALP activity was significantly higher in newborns of vitamin D-deficient compared with vitamin D-non-deficient mothers (median = 176 (IQR = 139-221) and 156 (IQR = 132-182), respectively, p = 0.04). A significant inverse correlation (Pearson's coefficient = - 0.18, p = 0.03) was observed between maternal 25(OH)D levels and babies' ALP activities. This association persisted in a multivariate logistic regression model (OR = 3.46, 95% CI 1.18-10.18, p = 0.024)., Conclusions: Our findings indicate that newborns of vitamin D-deficient mothers have higher serum ALP activity than those of non-deficient mothers, which might be related to increased bone turnover rather than just being a marker for bone formation. This could have a potential negative impact on fetal bone development and subsequent skeletal growth.

Background: Poor patients have greater morbidity and die up to 10 years earlier than patients who have higher socio-economic status. These findings are often attributed to differences in life-style between groups. The present study aimed at investigating the extent to which physicians contribute to the effect by providing relative poorer care, resulting in relative neglect in terms of time spent with a poor patient and more inaccurate diagnoses., Methods: A randomised experiment with 45 internal medicine residents. Doctors diagnosed 12 written clinical vignettes that were exactly the same except for the description of the patients' socio-economic status. Each participant diagnosed four of the vignettes in a poor-patient version, four in a rich-patient version, and four in a version that did not contain socio-economic markers, in a balanced within-subjects incomplete block design. Main measurements were: diagnostic accuracy scores and time spent on diagnosis., Results: Mean diagnostic accuracy scores (range 0-1) did not significantly differ among the conditions of the experiment (for poor patients: 0.48; for rich patients: 0.52; for patients without socio-economic markers: 0.54; p > 0.05). While confronted with patients not presenting with socio-economic background information, the participants spent significantly less time-to-diagnosis ((for poor patients: 168 s; for rich patients: 176 s; for patients without socio-economic markers: 151 s; p < 0.01), however due to the fact that the former vignettes were shorter., Conclusion: There is no reason to believe that physicians are prejudiced against poor patients and therefore treat them differently from rich patients or patients without discernible socio-economic background.

Oncocytic tumors are epithelial neoplasms that occur in various organs, including adrenal glands. Oncocytic adrenocortical adenomas and carcinomas are uncommon but well-known pathological entities in adults. However, generally oncocytic tumors, particularly in the adrenal glands, are very rare in the pediatric age-group. Most oncocytic adrenal tumors are not functional. We present a rare case of right-sided, functional oncocytic adrenocortical adenoma in a 5-year-old boy, who presented with clinical manifestations of precocious puberty and Cushing syndrome. Laparoscopic adrenalectomy showed a well-defined mass weighing 8.4 g and measuring 3 cm in maximum dimension. Histological examination demonstrated no features suggestive of aggressive biological behavior. The patient showed no evidence of recurrent or metastatic disease and continued to have normal serum hormonal levels 28 months following the surgery. In this report, we discuss the clinicopathological characteristics of this rare pathological entity and briefly review the literature on functional oncocytic adrenal tumors in the pediatric population.

Aim: To measure the health related quality of life (HRQoL) among Saudi Arabian adolescents with type 1 diabetes mellitus (T1DM) and the impact the disease has on the family., Methodology: A cross sectional study was conducted involving 315 adolescent patients (12-18 years) and their caregivers. Adolescent HRQoL was assessed by adolescents and their parents completing the Peds QL™ Diabetes Module 3.0. Family impact was assessed by the parent completing the Peds QL™ Family Impact module (FIM)., Results: Adolescents reported a cumulative mean HRQoL score of 64.8, while parents reported significantly lower scores of 60.3 (p=0.003). The lowest scores reported by both adolescents and parents were for "Worry". Female gender and late adolescent age were predictors of lower HRQoL for adolescents with T1DM. The FIM showed low scores for "Emotional functioning" (59.8) and high scores for "Family relationships" (80.9)., Conclusion: These findings emphasize the importance of an interdisciplinary, biopsychosocial and family centered care approach to adolescents with a chronic disease. Future work could assess the effectiveness of direct care involvement of adolescent and mental health experts in improving the HRQoL for this population., (Copyright © 2016 The Authors.

Purpose: With the increasing burden of noncommunicable disease, adolescence is viewed as an opportune time to prevent the onset of certain behaviors and promote healthy states. Although adolescents comprise a considerable portion of Saudi Arabia's population, they have received insufficient attention and indicators of their health status, as a first step in a prevention cycle are unavailable. This study was carried out with the aim of identifying the health risk behaviors and health status of adolescents in Saudi Arabia., Methods: This cross-sectional, school-based study was carried out in all 13 regions of Saudi Arabia. Through multistage, cluster, random sampling, intermediate, and secondary school students were invited to participate. Data were collected by means of a self-administered questionnaire addressing health risk behaviors and health status, clinical anthropometric measurements, and laboratory investigations., Results: A total of 12,575 adolescents participated. Various health risk behaviors, including dietary and sedentary behaviors, lack of safety measures, tobacco use, bullying, and violence were highly prevalent. Twenty-eight percent of adolescents reported having a chronic health condition, 14.3% reported having symptoms suggestive of depression, 30.0% were overweight/obese, and 95.6% were vitamin D deficient., Conclusion: Behaviors and conditions known to persist into adulthood and result in morbidity and premature mortality are prevalent among adolescents in Saudi Arabia. Preventive measures and local health policies are urgently needed and can impact adolescents and future adults. Establishing adolescent health surveillance is necessary to monitor trends and impacts of such measures., (Copyright © 2015 Society for Adolescent Health and Medicine. Published by Elsevier Inc.

Objective: The purpose of the study was to assess the relationship between students' perception of course/block coordinators performance and attributes with students' assessment scores in respective courses., Methods: This retrospective data based study was conducted at the College of Medicine, King Saud bin Abdulaziz University of Health Sciences (KSAU-HS). It was started in March 2013 and completed in June 2013 after the graduation of the fourth cohort. Exam score of 3(rd) and 4(th) cohort of students from the courses taught in the last two years of medical school were correlated with faculty and block evaluation done by the students. Scores from mid-block MCQs, portfolio scores, OSCEs and end-of-block MCQs were obtained., Results: The Mean scores of all the assessments for all five blocks were not significantly different for both batches. There was significant difference between block coordinators for students' score on portfolio, midterm exam and the final written exam. The students' Score in OSCE had significantly strong correlation with quality of station monitors, coverage of content and flow between stations. Student's perception of the commitment and motivation of the coordinator was strongly correlated with block organization, availability of clinical cases, performance of block coordinator, cooperation with students, and organization of clinical activities., Conclusions: Block coordinator's motivation and commitment affects quality of block organization and student`s success. Faculty training programs should include block management competencies and components identified through self-determination theory for improving the intrinsic motivation for students success.

Over the last 20 years, recombinant human growth hormone (somatropin) has been the cornerstone of managing children with growth hormone deficiency (GHD). Although both international and national guidelines for growth hormone (GH) therapy exist, there is currently no consensus on the optimal use of GH therapy in Gulf Cooperation Council (GCC) countries. The goals of GH therapy are to normalize height during childhood, attain normal adult height and correct metabolic abnormalities related to GHD. However, extended use of GH >50 µg/kg/day may increase frequency of adverse events. Here, we report the proceedings from a meeting of nine GCC pediatric endocrinology experts, which took place in Beirut in November 2011. The meeting was also attended by three European counterparts and aimed to provide consensus on best practice in the management of children with GHD in the GCC based on current local medical and regulatory environments.

Background and Objectives: To determine factors associated with pubertal gynecomastia., Design and Settings: A cross-sectional study among healthy male school children and adolescents in Riyadh, Saudi Arabia., Methods: Subjects were selected from diverse socioeconomic backgrounds. Tanner stage, height, weight, blood hormonal levels (leutilizing hormone [LH], follicle-stimulating hormone [FSH], total testosterone, and estradiol), and anthropometric and lipid parameters (body mass index [BMI], triglycerides, high-density lipoprotein [HDL], and low-density lipoprotein [LDL]), were collected and compared in children with and without gynecomastia., Results: The study included 542 children and adolescents. Median (interquartile range) age in the whole group was 11(8-13) years. The prevalence of gynecomastia was 185/542 (34%), with a peak at age 14. The 2 groups compared had nonsignificant difference in cholesterol (P=.331), LH (P=.215) and FSH (P=.571) levels. Those with gynecomastia were significantly older, had lower gonad stage, had higher anthropometric (height, weight, and BMI), and lipid (triglycerides, HDL, and LDL) values. In multivariate regression analysis, factors significantly associated with gynecomastia were BMI (odds ratio [OR]=1.05; 95%CI 1.00-1.10; P=.013), HDL (OR=0.42; 95%CI 0.19-0.92; P=.03), and gonad (Stage II OR=2.23; 95%CI 1.27-3.92; P=.005, Stage III OR=6.40; 95%CI 2.70-15.0; P < .0001, Stage IV OR=3.24; 95%CI 1.32-7.95; P=.01, Stage V OR=1.37; 95%CI 0.52-3.56; P=.53, compared with stage I)., Conclusion: Pubertal gynecomastia tends to increase in mid-puberty. In our setting, BMI, HDL, and gonad stage were the major factors associated with the development of pubertal gynecomastia.

This study was conducted to determine the causes and clinical presentations of osteomalacia/rickets in adolescents seen at the King Abdulaziz Medical City (KAMC), Riyadh. Because osteomalacia and rickets constitute the same entity, the term osteomalacia will be used for future discussion. A retrospective file review was performed on all adolescents (10-16 years) with osteomalacia, defined as alkaline phosphatase levels ≥500 IU/L, seen at the KAMC, Riyadh, from 2000 to 2006. We recorded the signs and symptoms, dietary history and amount of sun exposure at presentation. A total of 135 patients were found to fit the inclusion criteria for the study. Of them, 57 had nutritional causes, with a mean age of 13.2 years, and included 32 females. At diagnosis, 22 patients were found to have bone pain, 10 had bone deformities, eight had pathological fractures and 17 were asymptomatic. Secondary causes for osteomalacia were found in 59 cases who had liver and renal disease and in 19 other patients who were on medications such as anticonvulsants and steroids, which are known to cause osteomalacia. Our study indicates that osteomalacia is a significant health burden that deserves special attention. Bone pain is the most common presenting symptom at diagnosis. Because of the high risk of osteomalacia associated with the use of anticonvulsants and steroids, it is advised that all patients on these drugs should be routinely screened for secondary osteomalacia.

Puberty is the gradual transition period between childhood and adulthood. Many factors may contribute to the onset of puberty. The objective of the study was to determine the age of onset of secondary pubertal characteristics among Saudi Arabian girls. A cross-sectional study was conducted using a cluster sample design. Seven hundred and twenty-five schoolgirls between the ages of 6 and 16 years from diverse socioeconomic levels were included. During physical examinations, the height and weight of the girls were recorded, and the stages of breast and pubic hair development were determined according to Tanner stages; axillary hair development was determined according to modified stages. The median age at Tanner stage 2 for breast and pubic hair development was 10 years. The median age at stage 2 in modified scales for axillary hair development was 12 years. In conclusion, the median age of the onset of breast development at Tanner stage 2 for Saudi girls in Riyadh is lower than what has been reported in some countries in Europe, South Africa, Turkey and India but similar to girls in Hong Kong, China and white girls in the USA, which may support secular trends of an earlier onset of puberty.

Background: Cardiovascular disease (CVD) is a leading cause of death worldwide. CVD-related mortality can be substantially reduced by modifying risk factors., Methods: In this cross-sectional study conducted in King Abdulaziz Medical City, Riyadh, we estimated and compared prevalence of self-reported risk factors for CVD among physicians and a comparative group of non-physician health workers. We postulated that prevalence of CVD risk factors would be significantly lower in physicians. Participants filled in a structured self-administered questionnaire on CVD risk factors., Results: The study included 200 participants (100 respondents each group). Participants in the two groups were of similar age (P = 0.46) and Body Mass Index (BMI) P = 0.11. There was no statistical difference in smoking, frequency and length of physical exercise per week (P = 0.53, 0.57, 0.47 respectively). Diet habits showed daily intake of more protein, less fat and highly processed food, and similar vegetables, fruit and carbohydrate among physicians. Health status (presence of hypertension, diabetes, or dyslipidemia, or other diseases) didn't differ between the two groups. Physicians showed a significantly higher familial cardiovascular risk, with mothers and siblings having more dyslipidemia, but there was no significant difference in parental dyslipidemia, diabetes or hypertension., Conclusion: These findings indicate that high awareness of CVD and associated risk factors alone is not enough to prevent their occurrence. Programs to routinely screen these risk factors and improve the lifestyle of physicians are needed.

Saudi Arabia (SA), the largest country in the Gulf Region, has witnessed unprecedented expansion in undergraduate medical education (UME) with more than 200% increase in medical schools over the last five years. Such rapid expansion creates major challenges in relation to quality of outcomes to the extent that some authors argue that SA needs reform similar to Abraham Flexner. This may explain the strong movement towards accreditation of UME in SA but it is important to reflect on purpose of accreditation and learn from the experience of developed countries. In USA, more than 100 years ago Flexner used a predetermined gold standard to judge all medical schools and resulted in closing more than 50% of the medical schools at that time. For accreditation to fulfill its promises in ensuring quality of UME, it has to reassure stakeholders of its contribution to their culture of quality rather than an external judge of their quality. Recently, the World Federation for Medical Education recognizes that the presence of accreditation systems "does not provide a guarantee that the system is working and resulting in trustworthy decisions on the quality of programs in medical education". However, there must be a way of introducing quality management that maintain recent needed quantity development of UME in SA while ensuring the quality of products of medical schools. This paper describes accreditation development in SA and suggests a strategy for creating a culture of quality in medical schools in preparation for meaningful accreditation systems that ensure proper participation of all stakeholders in quality management on basis of evidence.

Objective: To assess the effect of education and economic status of parents on obesity in children., Methods: A cross-sectional survey was conducted in 2006 among school children in Riyadh, Saudi Arabia. A representative sample of 1243 (542 male and 701 female) children aged 6-16 years were contacted using multistage cluster sampling strategy. Social and demographic variables were collected using questionnaires completed by parents. Height and weight of the children were recorded by a trained team., Results: The mean body mass index for all children was 19.8±5.4. The prevalence rates of overweight and obesity were 21.1% and 12.7%, respectively. Overweight and obesity were more prevalent in males than in females. By multivariate analysis, children were more likely to be overweight if they were male (OR=0.6, p<0.01), 12 years of age (OR=3.79, p<0.01, compared to age 6 years), and if their families had higher income (OR=3.12, p<0.01, compared to families with low income). Being male (OR=0.545, p<0.01), aged 12 years (OR=3.9, p=0.005, compared to the age of 6), and having a mother who is more educated were determined to be significant risk factors for obesity in children. Mothers educated at university level were found to have a three-fold higher risk of having obese children(OR=3.4, p<0.01, compared to mothers with lower education levels)., Conclusions: Overweight and obesity among Saudi children is associated with educated mothers and higher family income. This finding calls for introducing interventions in health education for both children and parents.

A treatable and preventable disorder, congenital hypothyroidism (CH) is still a common cause of mental retardation. A 17-year-old Saudi boy with CH due to an ectopic thyroid gland was diagnosed by the neonatal screening program.Thyroxine replacement therapy was started for one month when the family chose to discontinue medication and follow-up. He was not then seen until 11 years of age. Thyroxine was restarted with a close follow-up, although thyroid function tests gradually improved back to normal levels, but his final height was short (159 cm) and IQ was negatively affected. Despite the diagnosis having been made at an appropriate time, patient was lost to follow up. This indicates an obvious flaw in the system for follow-up care. We recommend a registry of patients with CH to monitor their care. The aim of such a registry would be to monitor the efficiency and efficacy of neonatal screening.

Constitutionally tall stature (CTS) in children is a normal variant of growth within populations. Based mainly on psychological factors, sex steroids have been prescribed since the 1950s to induce puberty, as a mean to reduce final adult height. Controversy remains in the treatment of CTS, as well as lack of established criteria for initiating treatment. We report a constitutionally tall Saudi boy who was treated with sex steroids and was successful in reducing his final adult height.

Objective: Mutations in the KCNJ11 and ABCC8 genes that encode the pancreatic K(ATP) channel are the commonest cause of permanent neonatal diabetes mellitus (PNDM). The authors aimed to define the genetic causes of PNDM in a large cohort of Arab patients and compare them with a British cohort tested in the same laboratory., Design: Retrospective observational study., Setting: International genetics centre., Patients: Arab and British subjects with PNDM who were referred for genetic testing over the same period., Intervention: Comparison of genotypes and phenotypes between the two cohorts., Main Outcome Measures: The aetiology and phenotype of PNDM in an Arab compared to a British cohort., Results: 88 Arab and 77 British probands were referred between 2006 and 2011, inclusive. Consanguinity was higher among Arabs (63.6% vs 10.4%) and a higher percentage had a genetic diagnosis compared to the British cohort (63.6% vs 41.6%). Recessive EIF2AK3 gene mutations were the commonest cause of PNDM in the Arab cohort (22.7%) followed by INS (12.5%), and KCNJ11 and GCK (5.7% each), whereas K(ATP) channel mutations were the commonest cause (29.9%) in the British cohort. In 37.5% of Arab patients PNDM was part of a genetic syndrome compared to 7.8% of the British cohort., Conclusion: PNDM in the Arab population has a different genetic spectrum compared to British patients where KATP channel mutations are the commonest cause, similar to other European populations. In Arabs, PNDM is more likely to be part of a recessively inherited syndrome, possibly due to the higher rate of consanguinity.

Background and Objectives: Increasing numbers of children with chronic health conditions are now surviving into adolescence and adulthood because of advancing health care. These chronic health conditions are generally known to impact a child's growth and development, including pubertal development. In Saudi Arabia, chronic diseases are prevalent, yet no reports of pubertal onset and its relation to chronic illness are available. The aim of this study was to explore pubertal development among Saudi children and adolescents with a chronic illness., Design and Setting: Cross-sectional study conducted at schools in Riyadh, Saudi Arabia in 2006., Subjects and Methods: Those students whose parents reported that their son/daughter had a chronic illness and/or was taking a long-term medication underwent a physical examination to determine sexual maturity rating and growth parameters., Results: Of 1371 students who participated in the study, 155 (11.3%) had a chronic illness. Of those, 79 (51%) were male, and the mean SD age of all the students was 11.4 (2.4) years. Ninety (58%) students were taking medication for their health condition. Bronchial asthma was reported to be the most common chronic condition (n=66; 42.6%), followed by blood disorders (n=41; 26.5%). Fifty-three (34%) students were overweight or obese. For male gonadal (G) development, the mean age of boys with G stage 2 was 11.7 years; stage 3: 13.5 years; stage 4: 14.1 years; and stage 5: 14.6 years. For female breast (B) development, the mean age of girls with B stage 2 was 10.7 years; stage 3: 11.3 years; stage 4: 12.4 years; and stage 5: 14.1 years. The pubic hair development for both boys and girls was similar to the corresponding gonadal or breast development, respectively., Conclusions: The age of onset of pubertal development for both boys and girls with a chronic illness are within normal limits. The high prevalence of overweight and obesity may contribute to this phenomenon, yet further studies should consider the effects of disease severity and chronicity and medication use as possible confounders.

Background/aims: Familial glucocorticoid deficiency type 1 (FGD1) is a rare autosomal-recessive disorder resulting from defective ACTH receptor (melanocortin receptor type 2, MC2R). Individuals with this condition usually present in infancy or early childhood with the signs and symptoms of isolated glucocorticoid deficiency. To date, hypothyroidism has been reported as an associated feature in a few cases. The clinical findings along with MC2R genetic analysis of five Arab kindreds are described., Subjects/methods: The subjects were children with the clinical and biochemical features of FGD1. Three patients had associated thyroid dysfunction and two patients had associated growth hormone deficiency (GHD). Mutation analysis of MC2R was performed by direct gene sequencing., Results: Analysis of the MC2R gene revealed a homozygous insertion of a cytosine nucleotide between codons 153 and 154 (c.459&#95;460insC) in all of the patients. This mutation would be expected to cause a translation frame shift after codon 154 and a premature termination codon at 248 of the MC2R mRNA (p.I154fsX248)., Conclusions: Associated thyroid dysfunction and GHD were clinical features in the Bedouin patients with FGD1 caused by identical homozygous frameshift mutation in the MC2R gene., (Copyright © 2011 S.

Background: The ages of onset of pubertal characteristics are influenced by genetic, geographic, dietary and socioeconomic factors; however, due to lack of country-specific norms, clinicians in Saudi Arabia use Western estimates as standards of reference for local children., Aims: The aim of the Riyadh Puberty Study was to provide data on pubertal development to determine the average age of onset of pubertal characteristics among Saudi boys., Methods: Cross-sectional study among male school children in Riyadh, Saudi Arabia, in 2006, 542 schoolboys, aged 6 to 16 years old, from diverse socioeconomic levels were selected into the sample using a cluster sample design. Tanner stages were ascertained during physical examination by pediatric endocrine consultants, and also trained pediatric residents and fellows., Results: The mean age (standard deviation) at Tanner Stages 2, 3, 4, and 5 for pubic hair development of Saudi boys was 11.4 (1.6), 13.3 (1.3), 14.4 (1.0) and 15.1 (0.8) years old, respectively. For gonadal development, the mean age (standard deviation) at stages 2, 3, 4, and 5 were 11.4 (1.5), 13.3 (1.2), 14.3 (1.1) and 15.0 (0.9) years old, respectively., Conclusion: The ages of onset of pubertal characteristics, based on gonadal development, among Saudi boys are comparable to those reported in Western populations.
