Effectiveness of Insulin Pump Therapy Versus Multiple Daily Injections for Glycemic Control and Rate of Diabetic Ketoacidosis Among Children With Type 1 Diabetes Mellitus.

Background Advances in pump technology and the availability of insulin analogs, as well as the results of the Diabetes Control and Complications Trial (DCCT), which established the benefit of improved glycemic control, have all contributed to the increased use of insulin pump therapy in recent years, particularly in children. Purpose This research aims to compare the impact of insulin delivery method, i.e., continuous subcutaneous insulin infusion (CSII) or multiple daily injections (MDI) on glycemic control and the rate of diabetic ketoacidosis (DKA) among children with type 1 diabetes mellitus in Al Ahsa, Saudi Arabia. Methods  A retrospective cohort study was carried out in a diabetic center in Al Ahsa, Saudi Arabia, over 24 months (2020-2022) among children with type I diabetes mellitus (age group 1-14 years). Results  In total, 351 patients with diabetes were induced, with 316 (90%) on MDI and 35 (10%) on CSII. After six months of diagnosis, precisely 38 (12%) of patients with diabetes on the MDI regimen experienced DKA, compared to 4 (11.4%) of those on the CSII regimen, with no statistically significant difference (P=0.918). At six months and nine months of follow-up, the average hemoglobin A1c (HbA1c) was considerably higher in diabetic patients on MDI (8.9 ± 1.7% vs. 8.2 ± 1.5% and 9.1 ± 1.6% vs. 8.0 ± 1.3%, respectively, with a significant p-value ≤0.05). Conclusion In this study, we found that patients on the MDI regimen had considerably higher HbA1c levels than patients on the CSII regimen, but there was no statistically significant difference in DKA rates between them. This is a short-term follow-up study, and we recommend that patients be followed for a longer period of time for further accurate outcomes.

The Outcome of Congenital Cardiac Surgery in Patients with Down Syndrome: Single-Center Experience.

OBJECTIVES: This study aimed to describe the outcomes of Down syndrome patients who underwent cardiac surgery for congenital heart defects and to develop risk prediction models for in-hospital mortality, recurrent hospital admission, and the need for catheter intervention among a cohort of patients. METHODS: This single-centre retrospective cohort study included consecutive Down syndrome patients who underwent cardiac surgery for congenital heart defects between January 2018 and December 2021. We reviewed the electronic medical records. Two hundred patients fulfilled the eligibility criteria with complete data reporting. The patients' perioperative data and outcomes were recorded. RESULTS: Females constituted 56.5%. Most (78.5%) patients showed accepted recovery. The incidence of all-cause in-hospital mortality was 3.0%. The rates of the need for a second operation, heart failure management, and permanent pacemaker insertion were 3.0%, 2.0%, and 2.5%, respectively. Only 8 (4.0%) patients stayed in the hospital for a long duration after chylothorax or tracheostomy (if intubated more than 2 weeks). The model had an accuracy of 99% and included the intraoperative transesophageal echocardiography (TEE) abnormalities (residual heart lesions) (adjusted odds ratio [AOR]: 26.541, p = 0.033), the duration of mechanical ventilation following the operation (AOR: 1.152, p = 0.009), and the occurrence of postoperative heart block (AOR: 76.447, p = 0.005). CONCLUSION: Surgical treatment of congenital heart defects in Down syndrome patients had good outcomes with accepted recovery (without intra-hospital or during follow-up mortality or morbidity) of 78.5% and a 3% incidence of in-hospital mortality. Though, the occurrence of chylothorax was considerably high, and resulted in a long hospital stay (more than 10 days). Repair of tetralogy of Fallot and coarctation of the aorta were associated with an increased likelihood of catheter intervention following the operation.

Predicting the development of T1D and identifying its Key Performance Indicators in children; a case-control study in Saudi Arabia.

The increasing incidence of type 1 diabetes (T1D) in children is a growing global concern. It is known that genetic and environmental factors contribute to childhood T1D. An optimal model to predict the development of T1D in children using Key Performance Indicators (KPIs) would aid medical practitioners in developing intervention plans. This paper for the first time has built a model to predict the risk of developing T1D and identify its significant KPIs in children aged (0-14) in Saudi Arabia. Machine learning methods, namely Logistic Regression, Random Forest, Support Vector Machine, Naive Bayes, and Artificial Neural Network have been utilised and compared for their relative performance. Analyses were performed in a population-based case-control study from three Saudi Arabian regions. The dataset (n = 1,142) contained demographic and socioeconomic status, genetic and disease history, nutrition history, obstetric history, and maternal characteristics. The comparison between case and control groups showed that most children (cases = 68% and controls = 88%) are from urban areas, 69% (cases) and 66% (control) were delivered after a full-term pregnancy and 31% of cases group were delivered by caesarean, which was higher than the controls (χ2 = 4.12, P-value = 0.042). Models were built using all available environmental and family history factors. The efficacy of models was evaluated using Area Under the Curve, Sensitivity, F Score and Precision. Full logistic regression outperformed other models with Accuracy = 0.77, Sensitivity, F Score and Precision of 0.70, and AUC = 0.83. The most significant KPIs were early exposure to cow's milk (OR = 2.92, P = 0.000), birth weight >4 Kg (OR = 3.11, P = 0.007), residency(rural) (OR = 3.74, P = 0.000), family history (first and second degree), and maternal age >25 years. The results presented here can assist healthcare providers in collecting and monitoring influential KPIs and developing intervention strategies to reduce the childhood T1D incidence rate in Saudi Arabia.

Effects of dietary supplementation with microbial phytase on the growth, bone minerals, antioxidant status, innate immunity and disease resistance of African catfish fed on high soybean meal-based diets.

The microbial phytase, derived from Buttiauxella gaviniae, Yersinia mollarettiv and Hafnia spp., is proven to be safe for avian and porcine feeding and promotes their overall growth performance. Here, we have evaluated microbial phytase's effects on the growth, bone mineral content, antioxidant status, immune responses and the resistance of African catfish (Clarias gariepinus) fed with high soybean meal-based diets against Aeromonas hydrophila infection. Five isonitrogenous diets (40% protein) were supplemented with different levels of microbial phytase ranging from 0 as a control to 250, 500, 750 and 1000 FTU/kg diet. African catfish (n = 300; 8.5 ± 0.3 g) were allocated in 15 50-L tanks (in triplicates) and were fed on the prepared tested diets for 12 weeks. After the end of the feeding period of 12 weeks, 10 fish from each replicate was intraperitoneally infected with A. hydrophila (0.5 × 105 CFU/ml) and monitored for 14 days. Dietary phytase levels linearly and quadratically improved the growth performance of African catfish and stimulated feed intake. Bone levels of calcium, phosphorus, magnesium and zinc were also positively modulated in phytase-fed fish, especially at 750-1000 FTU/kg diet. Similarly, counts of red and white blood cells as well as haemoglobin, packed cells volume, platelets, lymphocytes and heterocytes were significantly modulated in all fish fed with phytase-supplemented diets. Higher levels of serum total protein, albumin and globulin were also observed in fish fed with a 750-1000 FTU/kg diet of phytase. Conversely, aspartate and alanine aminotransferase activities were lower in fish fed with a 750-1000 FTU/kg diet of phytase, compared to those fed the control diet. Moreover, antioxidant enzymes (superoxide dismutase, catalase and glutathione peroxidase), reduced glutathione levels and immune responses (lysozyme, respiratory burst, protease and alkaline phosphatase activities) biomarkers were linearly and quadratically elevated, while malondialdehyde values were linearly and quadratically decreased in fish groups fed with phytase-based diets. After administering A. hydrophila, 60.0% of the fish fed the control diet perished, while no mortalities were observed in fish fed with 750-1000 FTU/kg diets. Taken together, the current study reveals that dietary phytase could improve the growth performance, blood profile, bone mineralization, antioxidant activities, immunity and overall protection of African catfish against A. hydrophila infection. Dietary phytase may be efficiently used in the feeding of African catfish to enhance their overall performance and mitigate health conditions with optimum level of 900 FTU/kg diet.

Predictors of major adverse events and complications after ventricular septal defects surgical closure in children less than 10 kg.

BACKGROUND: Ventricular septal defect (VSD) is the most common congenital cardiac defect for which outcomes are not uniform. There is a lack of consensus on the risk factors for the unfavorable outcomes following surgical VSD closure. AIM: The aim of this study was to determine the risk factors and the predictors of major adverse events (MAEs) and complications following surgical closure of VSD in children weighing less than 10 kg. METHODS: This retrospective cohort study included children less than 10 kg who underwent surgical closure of congenital VSD of any type with or without associated congenital heart diseases. Patients with associated major cardiac anomalies were excluded. Preoperative, operative and postoperative data were collected from medical records. RESULTS: This study included 127 patients 52.8% were males, the median age was 8.0 months (IQR = 6.0-11.0 months), and their median weight was 5.7 kg (IQR = 4.8-7.0). Mortality was in one patient (0.8%) Multivariable logistic regression analysis revealed that male sex group (observational data), previous pulmonary artery banding (PAB), and significant intraoperative residual VSD were significant risk factors for the development of MAEs (odds ratios were 3.398, 14.282, and 8.634, respectively). Trisomy 21 syndrome (odds ratio: 5.678) contributed significantly to prolonged ventilation. Pulmonary artery banding (odds ratio: 14.415), significant intraoperative (3 mm) residual VSD (odds ratio: 11.262), and long cross-clamp time (odds ratio: 1.064) were significant predictors of prolonged ICU stay, whereas prolonged hospital stay was observed significantly in male sex group (odds ratio: 12.8281), PAB (odds ratio: 2.669), and significant intraoperative (3 mm) residual VSD (odds ratio: 19.551). CONCLUSIONS: Surgical VSD repair is considered a safe procedure with very low mortality. Trisomy 21 was a significant risk factor for prolonged ventilation. Further, PAB, significant intraoperative residual of 3 mm or more that required a second pulmonary bypass, and a greater cross-clamp time were significant predictors of MAE and associated complications with prolonged ICU and hospital stay.

Total Testosterone to Estradiol Ratio as a Predictor Marker of Metabolic Syndrome in Males.

Nowadays, metabolic syndrome (MetS) represents a global health challenge in developed and developing countries. The sex hormones disorders in males are related to many clinical co-morbidities. This study aimed to evaluate the total testosterone (TT) to estradiol (E2) ratio as a predictor marker of MetS. This case-control study included 88 MetS patients and 88 healthy individuals (control), in the age range of 18-69 years who were selected among patients who were referring to an outpatient clinic, using a convenience sampling method. The study participants were selected based on their medical history and physical examination, which included waist circumference, blood pressure, serum E2, TT, fasting blood glucose (FBG), triglyceride (TG), and high-density lipoprotein-cholesterol (HDL-C). Diagnosis of MetS was confirmed according to the National Cholesterol Education Program Adult Treatment Panel III guidelines. The findings revealed that the mean TT level was significantly lower among patients with MetS (P<0.001), while the mean E2 level was significantly higher among patients with MetS (P<0.001). The mean TT to E2 ratio was significantly lower among patients with MetS (OR=9.6, P<0.001). There was a significant correlation between MetS components and TT to E2 ratio and waist circumference (WC) (r = - 0.49, P<0.0001). The means of weight, WC, blood pressure, and FBG levels were significantly higher in patients with MetS (P<0.001, P<0.001, P<0.001, P=0.04, respectively), and the lipid profile of patients with MetS was abnormal (TG, P<0.001, HDL-C, P<0.001). Eventually, it can be concluded that the TT to E2 ratio can be regarded as a significant predictor of MetS in males.

Bilateral absence: A rare anomaly of the gemelli muscles.

The superior and inferior gemelli are deep muscles of the gluteal region, that facilitate the maintenance of a dynamic stability of the hip joint. Their absence could increase the chances of failure in the management of total hip anthroplasty and column acetabular ring fractures. We present a case of an adult female cadaver, with bilateral absence of the superior and inferior gemelli muscles.

Impact of Illness Perception on the Health-Related Quality of Life of Patients Receiving Dialysis: A Cross-Sectional Study.

Background End-stage renal disease (ESRD) is a major health problem worldwide that is increasing in incidence, prevalence, and cost. Both the disease itself and negative illness perceptions negatively affect patients' health-related quality of life (HRQoL), morbidity, and mortality. This study assessed the relationship between illness perception and HRQoL. Methods This cross-sectional study was conducted among 342 patients at five dialysis centers in Jeddah, Saudi Arabia. We used a self-administered questionnaire that containing demographic questions, the Revised Illness Perception Questionnaire, and the Short Form 36 Health Survey Questionnaire. The data were analyzed using t-tests, analyses of variance, Pearson's correlation coefficients, and multiple linear regression analyses. Results The mean (SD) age was 46.1 (16.5) years and the majority were men (53.8%). Except for treatment control, all domains of illness perception were significantly correlated with HRQoL; however, the correlations were positive only for personal control and illness coherence. Identity, disease timeline (acute/chronic), consequences, illness coherence, and emotional representations were independent predictors of HRQoL; together explaining 35% of the variance. Lower emotional response was the only domain of illness perception significantly associated with better HRQoL in both dialysis modalities across all dialysis centers. Conclusion There were clear effects of illness perception on HRQoL, with emotional representations being the strongest predictor. As such, emotional representations should be targeted in interventions.

The efficacy and safety of percutaneous balloon angioplasty for aortic coarctation in children. Acute and mid-term results in a single center experience.

OBJECTIVES: To assess the efficacy and safety of balloon angioplasty (BAP) procedure for treatment of coarctation of the aorta (CoA) in children. Methods: A retrospective study included 27 consecutive children, underwent BAP for either native-CoA (Na-CoA) or recoarctation (Re-CoA). Medical records, echocardiographic findings, angiographic and hemodynamic data were collected from the hospital database. Follow­up was scheduled at 1, 3, 6, 12 months after the procedure. The study took place over a period of 4.5 years, from April 2014 to January 2019, in Madinah Cardiac Center, Madinah, Northwest region, Saudi Arabia. RESULTS: The mean age of patients was 11.86±8.96 months. Seven children had Na-CoA and 20 children had Re-CoA. The success rate of the procedure was achieved in 23 children (85%), as BAP reduced the mean systolic pressure gradient across the CoA (Na-CoA: from 45.28± 18.3 to 9.8± 6.57 mm Hg, p=0.0009), and in Re-CoA groups (from 42.48±16.7 to 10.9±8.5 mm Hg, p less than 0.0001). In mid-term follow-up, the need for re-intervention occurred in 8 children of the cohort (3 children [42.8%] from the Na-CoA group, and 5 children [25%] from the Re-CoA group).  Conclusions: Balloon angioplasty is considered a safe procedure for the management of CoA, but its efficacy remains questionable especially for young infants with Na-CoA type. However, it is a reliable option for managing Re-CoA children, with a lower rate of future re-intervention.

Transcatheter device closure of ventricular septal defects in children: a retrospective study at a single cardiac center.

BACKGROUND: Ventricular septal defect (VSD) is the most common congenital heart disease in the pediatric population. Nowadays, trans-catheter closure is considered a feasible method of therapy for most muscular and some perimembranous types of VSDs. OBJECTIVE: Assess the safety, efficacy and outcome of percutaneous transcatheter closure of VSDs in children. DESIGN: Retrospective, single center study. SETTING: Madinah Cardiac Center, Madinah, Saudi Arabia. PATIENTS AND METHODS: The study included all consecutive children who underwent transcatheter closure of isolated VSD during the period from December 2014 to January 2019. The data were collected from hospital database medical records. Transthoracic echocardiography (TTE) and an electrocardiogram (ECG) were done before and after the procedure in all the patients. The device was implanted by the retrograde or antegrade approach. All patients were subjected to follow-up evaluation at 1, 3, 6, 12 months, and annually thereafter with TTE and ECG. MAIN OUTCOME MEASURES: Procedure success rate, clinical follow-up, TTE. SAMPLE SIZE: 70 children. RESULTS: The mean (standard deviation) age of patients was 10.2 (4.1) years (range: 2-18 years), and their mean body weight was 30.9 (13.9) kg (range: 7.0-57.7 kg). Forty-eight (68.6%) children had muscular VSD (mVSD), and 22 (31.4%) children had perimembranous VSD (pmVSD). The majority of defects were closed via the retrograde approach using the Amplatzer muscular occluder device. At 24 hours after the procedure, the success rate was 90%. Only four (5.7%) cases had major adverse events including complete atrioventricular block, hemolysis, and thrombus formation. CONCLUSION: Transcatheter closure is a safe and feasible procedure in VSDs of various morphologies, with a low adverse event rate. LIMITATIONS: Retrospective design, single-center study, absence of control group. CONFLICT OF INTEREST: None.

The trends and patterns of congenital heart diseases at Madinah Cardiac Center, Madinah, Saudi Arabia.

OBJECTIVES: To characterize the pattern of congenital heart diseases (CHDs) in Madinah, Saudi Arabia. METHODS: We retrospectively collected and analyzed the demographic and diagnostic details of all patients with CHDs referred at Madinah Cardiac Center (MCC) over a period of 3 years from January 2017 to December 2019. RESULTS: During the study period, 1,127 patients with CHDs were identified. The male to female ratio was 1.1:1, with a mean age of 8.4±2.4 years. The acyanotic CHDs were the predominant lesions, accounting for 84.8% of all cases, while the cyanotic types accounted for 13%. Patent ductus arteriosus (PDA), ventricular  septal defects (VSD), atrial septal defects (ASD), coarctation of the aorta (CoA), and atrioventricular septal defect (AVSD) were the most common acyanotic CHDs and represented 27.9%, 24.8%, 18.9%, 6.4%, and 4.4% of the total cases, respectively. Tetralogy of Fallot (ToF) (8.7%), followed by transposition of the great arteries (TGA) (1.7%) and truncus arteriosus (1.1%), were the most common cyanotic CHDs. There was a male predominance of VSD, ToF, CoA, TGA, and truncus arteriosus. In contrast, PDA, ASD, and AVSD were more common in females.  Conclusion: The pattern of CHDs observed in our study and age at which the diagnosis of CHDs was made were different from the other national and international studies, which points to a diagnostic issue along with problems of awareness on the part of the general population.

Risk factors for prolonged mechanical ventilation after surgical repair of congenital heart disease. Experience from a single cardiac center.

OBJECTIVES: We studied these predictors at a single cardiac center. Methods: A retrospective cohort study was carried out after obtaining approval from the institutional review board. All patients (age, 0-14 years) who underwent  congenital heart disease (CHD)  surgery from January 2014 to June 2016 were included. Prolonged mechanical ventilation (PMV)  was defined as greater than 72 hours of ventilation. Results: A total of 257 patients were included, among whom 219 (85.2%) were intubated for greater than 72 hours and 38 (14.8%) were intubated for ≥72 hours. Age (29.9 versus 11.95 years), weight (9.6 versus 5.9 kg), cross-clamp time (CCT) (53.6 versus 71.8 min), cardiopulmonary bypass time (CBP) (80.98 versus 124.36 min), length of stay in the pediatric intensive care unit (PICU) (10.4 versus 27.2 days), infection (12.8% versus 42.1%), open sternum (0.9% versus 13.2%), re-intubation (19.2% versus 39.5%), pulmonary hypertension (10.9% versus 31.6%), and impaired heart function (10.1% versus 23.7%) were associated with PMV. In terms of Risk Adjustment in Congenital Heart Surgery (RACHS) classification, only patients with RACHS 4 (18.4%) were associated with the risk for PMV. Conclusions: Age, weight, CBP, CCT, pulmonary hypertension, impaired cardiac function, and sepsis are risk factors for PMV. These factors should be considered when deciding surgery and in providing PICU care.

Comparison of Saudi Arabian hemodialysis and peritoneal dialysis patients' illness perceptions.

The clinical outcome of patients with end-stage renal disease (ESRD) may differ according to their beliefs concerning their illness and its treatment. Both the disease itself and negative perceptions of the illness may increase patients' morbidity and mortality. This study aims to compare hemodialysis (HD) and peritoneal dialysis (PD) patients' illness perceptions and their related factors. This cross-sectional comparative study was conducted in five dialysis centers. After excluding patients with psychiatric comorbidities, 342 stable dialysis patients (HD, n = 267; PD, n = 75) completed a demographic questionnaire and the Revised Illness Perception Questionnaire (IPQ-R). The data were analyzed using t-tests and ANOVAs. Out of the 342 patients, 53.8% were male and 46.2% were female. Their mean age was 46.1 ± 16.5 years. Compared to the HD patients, the PD patients perceived their illness to be significantly less chronic (p = .029) and more controllable, whether through personal or treatment control (p = .012, p = .017). Patients' most common cause of attributions were stress, worry, or poor past medical care. PD showed an advantage over HD in terms of perceptions of ESRD chronicity and controllability. Intervention programs targeting illness perception are needed to support dialysis patients.

The Saudi clinical practice guideline for the management of overweight and obesity in adults.

OBJECTIVE: To assist healthcare providers in evidence-based clinical decision-making for the management of overweight and obese adults in Saudi Arabia. METHODS: The Ministry of Health, Riyadh, Kingdom of Saudi Arabia assembled an expert Saudi panel to produce this clinical practice guideline in 2015. In collaboration with the methodological working group from McMaster University, Hamilton, Canada, using the Grading of Recommendations, Assessment, Development and Evaluation (GRADE) approach, which describes both the strength of recommendation and the quality of evidence  RESULTS: After identifying 11 questions, corresponding recommendations were agreed upon as guidance for the management of overweight and obese adults. These included strong recommendations in support of lifestyle interventions rather than usual care alone, individualized counseling interventions rather than generic educational pamphlets, physical activity rather than no physical activity, and physical activity in addition to diet rather than diet alone. Metformin and orlistat were suggested as conditional recommendations for the management of overweight and obesity in adults. Bariatric surgery was recommended, conditionally, for the management of obese adults (body mass index of ≥40 or ≥35 kg/m2 with comorbidities).  CONCLUSIONS: The current guideline includes recommendation for the non-pharmacological, pharmacological, and surgical management of overweight and obese adults. In addition, the panel recommends conducting research priorities regarding lifestyle interventions and economic analysis of drug therapy within the Saudi context, as well as long term benefits and harms of bariatric surgery.

The spectrum of congenital heart diseases in down syndrome. A retrospective study from Northwest Saudi Arabia.

OBJECTIVES: To to define the frequency and patterns of congenital heart disease (CHD) among children with Down syndrome (DS) in Northwest Saudi Arabia.  METHODS: We included children with confirmed DS referred to the regional pediatric cardiology unit in Madinah Maternity and Children Hospital between January 2008 and December 2013. Children were identified from the unit's data-base and the charts were reviewed retrospectively. We excluded term and preterm children with patent ducts arteriosus (PDA) and persistent foramen oval spontaneously resolved during the first 4 weeks of life.  RESULTS: A total of 302 children with DS were identified (50.3% male). Of these, 177 (58.6%) had CHD. Atrioventricular septal defect (AVSD) was the most frequent lesion identified in 72/177 (40.7%) followed by mixed left to right shunt defects (14.7%) and secundum atrial septal defect (ASD) (11.8%). Ventricular septal defect was detected in 10.7% and 8.5% had PDA beyond the neonatal period. There was no gender difference in the frequency of CHD (p=0.9) and the presence of CHD was not related to the genetic cause of DS (p=0.9).  CONCLUSION: The frequency of CHD in our DS cohort is comparable with Europe, Asia ,and other KSA regions. However its pattern appears to be different from some areas in KSA.

Morphological Variation of Third Ventricle Using Computerized Tomography among Different Gender and Age Groups: A 5-Year Retrospective Study in Usmanu Danfodiyo University Teaching Hospital; Sokoto; North - West Nigeria

Background: Many methods have been described for measurements of the third ventricle as a means of evaluating brain atrophy during the normal aging process and disease. Enlargement of the cerebral ventricles is one of the most frequently replicated neurobiological findings in schizophrenia. The aim of this morphological study was to examine the range in the normal size of the third ventricle of individuals living in Sokoto and to assess its association with gender and age. Materials and Methods: All available brain CT in the Radiology Department of the Usmanu Danfodiyo University Teaching Hospital (UDUTH) Sokoto; Nigeria; from 2007 to 2012 (a 5-year period) and reported as normal by the radiologist were recruited for the study. Films were viewed on the computer monitor. Measurements were made with Dragon V 3.1.1 Philips and Neusoft Medical System Company Limited software; the software provides a meter rule with which measurements were done. Results: A total of 252 CT scan images where used in the study. Of this number; 156 (61.9) were CT scan images of males and 96 (38.1) were CT scan images of females. The mean width was 8.38 mm and mean anteroposterior length was 12.16 mm. These differences were statistically significant; P = 0.0209 (0.05). Conclusion: Our findings provide a base line data for the measurement of the third ventricles using CT scans in our environment and this may be applied in various clinical conditions involving the third ventricle

Pediatric heart diseases in Madina, Saudi Arabia. Current status and future expectations.

OBJECTIVE: To demonstrate the magnitude of pediatric heart disease problem in Madina, current situation of heart service, obstacles and future expectations. METHODS: We conducted this cross sectional study in Madina Maternity and Children Hospital, Madina, Kingdom of Saudi Arabia from January 2007 to June 2008. The study was approved by the Ethical Committee. A computer based program was established to register the data of all children attended the pediatric cardiology unit. RESULTS: A total of 4348 children were seen in the study period; 2301 were follow up cases while 2047 were new cases. Of the new cases, 794 (38.8%) were found to have heart diseases. Of this, 705 have CHD (cardiomyopathies 34, rheumatic heart disease 26, mitral valve prolapse 15, Kawasaki disease 9, and arrhythmia 5). Ventricular septal defect was the most common CHD (34.5%), and followed by atrial septal defect (8.9%). Other CHDs were as follows pulmonary stenosis (7.9%), patent ductus arteriosus (6%), atrioventricular septal defect (3.8%), aortic stenosis (3.5%), dextro-transposition of great arteries (3.5%), tetralogy of fallot (3%), coarctation of aorta (2.8%), and others (26%). Three hundred and ten patients required referral to the cardiac centers in Riyadh for catheterization or surgical intervention. Urgent referral was required in 128 patients. All patients were transferred via medical evacuation service. CONCLUSION: Pediatric heart disease constitutes a major health problem in Madina. The majority of patients have CHD. The need for cardiac centre in Madina was emphasized to avoid problems of transportations.

Splenectomized versus non-splenectomized patients with thalassemia major. Echocardiographic comparison.

OBJECTIVE: To study the effect of splenectomy in patients with thalassemia major on the cardiovascular system through echocardiographic study. METHODS: A prospective, cross sectional study was carried out from December 2006 to December 2007. Patients from the Thalassemia Center in the Maternity and Children's Hospital, Madina, Kingdom of Saudi Arabia, were screened by means of history, physical examination, laboratory studies, and echocardiography. RESULTS: Fifty-seven patients were studied: 36 were non-splenectomized, while 21 were surgically splenectomized. The 2 study groups were well matched for age, gender, height, and weight. The total amount of blood given during the previous year (6577.1+/-206.9 ml versus 5390.5+/-220.2 ml, p=0.0005), and the annual transfusion index (200.9+/-11.3 versus 134.1+/-7.3, p=0.0001) were significantly lower in the splenectomized group. There was no significant difference between the 2 groups regarding laboratory studies. Left ventricular systolic function shows no difference regarding fraction shortening between the 2 groups. The mitral valve E/A ratio was significantly higher in the splenectomized group (1.6+/-0.2 versus 1.4+/-0.2, p=0.02). The pulmonary artery pressure was higher in the splenectomized group (34.2+/-9.1 versus 20.8+/-9.2 mm Hg, p=0.0001). There was a significantly higher number of patients with pulmonary hypertension in the splenectomized group (14 [66.7%] versus 6 [16.7%], p=0.0004). CONCLUSION: Splenectomized patients with thalassemia major are at high risk of having impaired diastolic left ventricular function and pulmonary hypertension.

Anorexia nervosa. Emphasis on its medical complications.

Anorexia nervosa (AN) is a well-recognized heterogeneous psychiatric disorder, associated with high morbidity and mortality with several medical complications. Besides a brief review, this paper also reports on a single female patient with AN. Eating disorders are reported to be slightly more common among western cultures, but developing countries are not immune to eating disorders. This patient showed both the psychopathology of abnormal eating behavior and serious physical complications and despite all possible treatment interventions, she ultimately died. We discuss different aspects of AN including the importance of constant social support from key relatives.

Clinical pattern of seizures in hospitalized children.

OBJECTIVE: Seizures continue to be a major problem in the pediatric age group. The cause and clinical presentation of these seizures are vast and variable. This is a prospective study, conducted with the aim of assessing the magnitude and presentation of this problem in the region of Al-Madina Al-Munawara, Kingdom of Saudi Arabia. METHODS: All the cases of seizures admitted to Madina Maternity & Children`s Hospital, Al-Madina Al-Munawara, Kingdom of Saudi Arabia from April 2000 to July 2000 were included in the study. The age groups studied were from 8 days old to 14 years. RESULTS: Out of 1593 patients admitted to the Pediatric Department, 138 (8.7%) were admitted with seizures. Fifty-one (37%) cases were of established epilepsy, 42 (30.4%) of febrile convulsions and 27 (19.6%) of hypocalcemic convulsions. The rest of the total includes first attack of non-febrile seizure, neonatal seizures, encephalitis and drug toxicity. CONCLUSION: We observed and concluded that seizures due to epilepsy remain the most common cause, with febrile convulsion and hypocalcemic convulsion a second and third major causes. As observed, we also recommend further studies into the association of hypocalcemic seizures with underlying active rickets in the pediatric age group.
