Vitamin D deficiency is a clinical problem and recently we have shown that 82.5% of our entire study cohort had inadequate serum 25(OH)D levels. In this study, we analysed serum 25(OH)D levels of juvenile patients admitted to the Burjeel Hospital of VPS Health care in Abu Dhabi, United Arab Emirates (UAE) from October 2012 to September 2014. Out of a total of 7883 juvenile patients considered in this study, almost 58.1% of females and 43.3% of males in the age group of 1-18 years were found to have low serum 25(OH)D levels (

Familial glucocorticoid deficiency (FGD) is a rare autosomal recessive condition, characterized by marked atrophy of zona fasiculata and reticalaris with preservation of zona glomerulosa. Out of more than 50 published cases, 18 patients died as a result of glucocorticoid insufficiency. The main objective of this report is to emphasize the early diagnosis and treatment in our 17 month-old patient. Her presenting features following an upper respiratory tract infection were hypoglycemia, seizures as well as deep hyperpigmentation of the limbs and lips. A low cortisol concentration, elevated ACTH level and normal electrolytes and aldosterone level all supported the diagnosis of primary glucocorticoid deficiency. Parents were counseled about the diagnosis, management and the lifelong requirement of steroids. FGD is an easily treatable disease when recognized but frequently missed due to a non-specific presentation. FGD is a treatable disease, delayed diagnosis and treatment can lead to significant morbidity.

Background: Maintaining a normal vitamin D status is important for both skeletal and extra-skeletal health. Recent data show that vitamin D deficiency is endemic in women residing in the Arabian Gulf and is common in pregnant women and their newborns. The purpose of this study was to establish the vitamin D and calcium status of children in an urban ambulatory pediatric clinic in Abu Dhabi to determine for the prevalence of vitamin D deficiency in this cohort. Methods: Patients were recruited prospectively from the pediatric outpatient clinic visits, if they were having blood taken for laboratory investigations other than those related to vitamin D and calcium status. The vitamin D status was compared between 4 age groups (0–0.9 y, 1–1.9 y, 2–7.9 y and 8 -14 y) using the following definitions: deficiency < 25 nmol/l, insufficiency 25–50 nmol/l and sufficiency > 50 nmol/l. Results: A total of 183 children were included in the study. The percentage of females and males in the deficient range was 21% and 16% respectively, while 32% and 46% of females and males respectively were vitamin D sufficient. The highest prevalence of vitamin D deficiency occurred in the 8–14 y old age group with 31.2% being deficient. Conclusions: The study highlights that in an ambulatory pediatric clinic population, peri-pubescent children are most at risk of vitamin D deficiency. This age group is often not considered in the discussion for the need for vitamin D supplementation. Serious consideration should be given to including vitamin D supplementation in a school public health program in the UAE.

It has been previously documented that alphacalcidol (1α-hydroxyvitamin D 3 ) is inefficient in healing rickets, partly because it results in a suboptimal rise in 1,25-dihydroxyvitamin D (1,25-(OH) 2 D) and partly because it fails to replenish the store of 25-hydroxyvitamin D (25-OHD). However, very few studies have actually documented this outcome. The aim was to document biochemically the response to alphacalcidol and subsequently the change in response to ergocalciferol. This study was conducted at our institution from January 2005 till December 2008. We included all patients referred to our clinic with active rickets after a failed course of alphacalcidol. At baseline the median (IQR) for PTH l7.1 (4.5–35.3) pmol/L, 25-OHD 29.0 (18–66.2) nmol/L, 1,25-(OH) 2 D 205 (158.2–311.2) pmol/L and ALP 676 (462.5–1101.7) IU/L. After 3 months treatment with ergocalciferol the concentrations changed markedly with biochemical healing: PTH 4.5 (3.9–7.5), 25-OHD 143.5 (101.5–206.5), 1,25-(OH) 2 D 277 (221.0–572.7), ALP 369 (302.2–438.0). The results confirm the biochemical and physiological basis for using ergocalciferol (or cholecalciferol) in nutritional rickets. Unfortunately these forms are not readily available in many geographic areas. This supply problem together with marketing strategies forces physicians to make an incorrect choice of medication. Treatment with ergocalciferol was either with intramuscular stosstherapy or drops for 3 months. The former ensures compliance and is associated with higher 25-OHD and 1,25-(OH) 2 D concentrations.

Background: Vitamin D deficiency is still prevalent worldwide, including the Middle East. A cohort of patients with nutritional rickets was treated with vitamin D2 (ergocalciferol) alone. After this intervention, patients were followed to document changes in z scores for height after treatment. The secondary aim was to determine the proportion of affected children who had vitamin D deficiency or calcium deficiency. Methods: Z score for height was calculated as the difference between the observed value and the median value, divided by the SD of the population. Z scores were compared in patients before and after treatment. Results: The improvement in z score after treatment was 0.86 ± 0.95. The 95% confidence interval for the mean difference was 1.32–0.40 (t = 3.95, P

Respiratory syncytial virus (RSV) respiratory infections are very common during infancy and account for the majority of hospitalizations during the fall and winter seasons. Patients vary in the severity of their illnesses, with most hospitalized patients needing oxygen and intravenous fluids. The objective of this study was to assess in hospitalized patients the severity of the disease in relation to age. We compared children who were90 days old with children who were90 days old for the duration of oxygen therapy, maximum oxygen concentration used, duration of stay and duration of intravenous fluids. We conducted a retrospective case review of national children2 years admitted to the pediatric ward at Sheikh Khalifa Medical City with RSV proven bronchiolitis/pneumonia over a 3-month period from 1 September to 30 November 2001. Morbidity for group 1 (birth-90 days) and group 2 (91 days-2 years) was compared by the Mann-Whitney U-test using duration of oxygen therapy, maximum oxygen concentration used, duration of stay and duration of intravenous fluids. Multiple regression for duration of oxygen therapy was tested using the following risk factors as predictors: age group (1 or 2), previous ventilation, bronchopulmonary dysplasia (BPD) and prematurity. A total of 89 patients were admitted during this period. The mean age (SD) of group 1 (n = 28) and group 2 (n = 61) was 46.35 (25.57) days and 275.67 (156.79) days, respectively. The only statistically significant difference using the Mann-Whitney U-test was detected for duration of oxygen between the groups (p = 0.002). Using multiple regression, only age group acted as a predictor for duration of oxygen therapy (p0.001). This implies that the youngest children, group 1, are at a risk for prolonged oxygen therapy. Four patients from group 1 were admitted to the intensive care unit, of which two received ventilatory support. RSV respiratory infections affect infants3 months old in a more severe form than older infants. Even though overall duration of stay was similar for both groups, young infants who in fact did require oxygen had a more protracted and severe illness compared with the older infants. This was evidenced by their longer duration of oxygen and more frequent need to be managed in the intensive care unit.

Background Classic laryngotrachoebronchitis (LTB) is an inflammatory process, with oedema and secretions that involve the entire laryngotracheobronchial tree. The severity of lower airway disease in African children with LTB has previously been documented. The aim of the present study was to determine whether steroids prevent reintubation in African children with classic LTB.
