Higher prevalence of vitamin D deficiency in mothers of rachitic than nonrachitic children

Vitamin D deficiency [serum 25-hydroxyvitamin D <25 nmol/L (<10 ng/mL)] was identified in 92% of rachitic Arab children and 97% of their mothers compared with 22% of nonrachitic children and 52% of their mothers. There was a positive correlation between maternal and child vitamin D levels. We conclude that mothers of rachitic children should be investigated and treated for vitamin D deficiency.

The Role of Non-Contrast Cone Beam CT in Identifying Incomplete Treatment during Uterine Artery Embolization

PurposeTo describe the utility of post-procedure noncontrast cone-beam computed tomography (CT) in identifying cases of incomplete treatment and the need to search for additional vascular supply during uterine artery embolization (UAE).Materials and MethodsFrom June 2013 to June 2018, 427 patients (age, 45 ± 5 years) underwent 430 consecutive UAEs with post-embolization noncontrast cone-beam CT. If noncontrast cone-beam CT showed an area of the uterus lacking contrast retention, aortography was performed to search for collateral supply. Procedures were characterized as suspected complete bilateral UAEs or suspected incomplete UAEs, such as in cases of a unilateral uterine artery or diminutive uterine arteries. Rates of inadequate contrast retention on noncontrast cone-beam CT and discovered collateral artery supply were calculated. In 10 consecutive cases in which both noncontrast cone-beam CT and aortography were performed, dose-area product radiation exposure from noncontrast cone-beam CT and aortography was compared using a 2-sided paired-sample t-test.ResultsOf the 411 suspected complete bilateral UAEs, noncontrast cone-beam CT showed an area of the uterus lacking contrast retention in 38 (9.2%) cases. Of the 19 suspected incomplete UAEs, noncontrast cone-beam CT demonstrated incomplete treatment in 6 (31.6%) patients. Aortography was performed in 40 of the 44 cases of incomplete treatment on noncontrast cone-beam CT, and collateral supply was found in 28 (70.0%) cases. In 22 of these cases (5.2% of the 427 patients studied), noncontrast cone-beam CT led to the discovery of significant collateral supply requiring further embolization. Dose-area product radiation exposure from noncontrast cone-beam CT was less than from aortography (P = .007).ConclusionsPost-UAE noncontrast cone-beam CT can be used to select a subset of patients with a higher likelihood of collateral supply who may benefit from post-embolization aortography.     

Apparent Diffusion Coefficient of Uterine Leiomyoma as a Predictor of the Potential Response to Uterine Artery Embolization

PurposeTo determine the utility of the apparent diffusion coefficient (ADC) of uterine leiomyoma for prediction of the potential response to uterine artery embolization (UAE).Materials and MethodsThis prospective study included 49 patients with uterine leiomyomas who underwent diffusion-weighted magnetic resonance (MR) imaging before UAE between May 2011 and January 2012. All patients also underwent 3-month follow-up MR imaging after UAE. Using conventional and diffusion-weighted MR imaging sequences, 72 uterine leiomyomas ≥ 3 cm were prospectively evaluated. The volume of each leiomyoma was calculated, and quantitative measurement of ADC was performed. Regression analysis was used to evaluate the relationship between ADC and volumetric response after UAE. Receiver operating characteristic curve analysis was performed to determine the sensitivity and specificity of ADC for prediction of the potential response to UAE. Interclass correlation coefficient analysis was used to assess interobserver variability between two radiologists.ResultsVolume reduction rates of leiomyomas after UAE ranged from 0.2%–89.1% (mean, 44.1%). ADC ranged from 0.559 × 10^?3 mm²/s to 1.814 × 10^?3 mm²/s (mean, 1.170 × 10^?3 mm²/s). ADC was statistically significantly related to volumetric response of leiomyomas (P = .014). Using a threshold of 1.092 × 10^?3 mm²/s, the sensitivity and specificity of ADC for prediction of > 50% volume reduction of the leiomyoma after UAE were 82.6% and 52.3%, respectively. Using a threshold of 1.023 × 10^?3 mm²/s, the sensitivity and specificity of ADC for prediction of < 30% volume reduction were 80.8% and 33.3%, respectively. The interclass correlation coefficient for measuring ADC of uterine leiomyomas between two radiologists was 0.98.ConclusionsADC of uterine leiomyomas was significantly related to the volume reduction after UAE. ADC may be useful in predicting the potential response to UAE. A high ADC of the uterine leiomyoma may be associated with a greater volume reduction after UAE.     

Resolution of Uterine Arteriovenous Malformation and Maintenance of Reproduction in 20 Women Treated with a GnRH Agonist Concomitantly with an Aromatase Inhibitor and Tranexamic Acid

ObjectiveThis study investigated the efficacy of GnRH agonists concomitantly with transient aromatase inhibitor and tranexamic acid to treat women with uterine arteriovenous malformations (AVMs) associated with abnormal uterine bleeding (AUB) to preserve fertility and determine reproductive outcome.MethodsThis was a prospective cohort study in a tertiary centre. Doppler ultrasound demonstrated AVM in 19 women with AUB 1–28 weeks following spontaneous or therapeutic abortion and in one woman 4 years after normal pregnancy while taking an oral contraceptive. On the basis of experience from the first three cases, 17 women were treated with tranexamic acid (1 g three times daily orally for 5 days), a GnRH agonist (3.75–11.25 mg, for 1–3 months), plus an aromatase inhibitor (letrozole 2.5 mg once daily for 5days) with the initial injection of GnRH agonist. Two women required blood transfusion, and one required uterine tamponade with Foley catheter balloon in the first 48 hours to control heavy bleeding (Canadian Task Force Classification II-2).ResultsAll 20 AVMs resolved within 1–3 months of treatment. Of 16 women who attempted pregnancy, all (100%), including two who had uterine artery embolization (one after hysteroscopic septoplasty), conceived spontaneously with 18 live births. Two women are using contraception (one taking an oral contraceptive, one using a levonorgestrel intrauterine system), and one 40-year-old is not using contraception. One woman had hysteroscopic endometrial ablation followed by vaginal hysterectomy for AUB at 1 and 2 years later.ConclusionA GnRH agonist in combination with transient aromatase inhibitor and tranexamic acid is an effective management strategy to treat and maintain reproduction in women with AVMs associated with AUB.     

Diabetes mellitus and periodontal disease in the United Arab Emirates

The United Arab Emirates (UAE) form part of the Arabian peninsular with a population of about 4 million. One of the major health care challenges is the lack of national data, however, it is known that UAE has the second highest prevalence of diabetes worldwide with 25% of the population affected. Deaths related to diabetes are a serious problem and relate to genetic disposition, obesity, a sedentary lifestyle and physical inactivity, with a high genetic susceptibility to insulin resistance. Diabetics have a higher prevalence and more severe forms of periodontal disease which leads to an impaired quality of life and to oral functional disability. Periodontal disease is frequently overlooked as a complication of diabetes and there are few referrals from physicians or endocrinologists to dentists. There is a similar lack of data in UAE on oral health. Recommendations include strategies that focus on prevention of diabetes, improved awareness about diabetes at professional level and in the community, highlighting the importance of oral health.     

Food Sources of Fiber and Micronutrients of Concern in Infants and Children in the United Arab Emirates: Findings from the Feeding Infants and Toddlers Study (FITS) and the Kids Nutrition and Health Survey (KNHS) 2020

We estimated the usual intakes of fiber, iron, zinc, calcium, folate, vitamin D, and vitamin A and the top foods that contribute to them among children in the UAE. Dietary intake was assessed using 24 h recalls among 5 age groups of infants and children. Foods were clustered into 54 food groups and ranked by their percentage contribution to the nutrients of interest in this study. The percentage achieving the adequate intake (AI) of fiber was negligible among all children. The top source of fiber was vegetables among children under 4 years, and white breads among those over 4 years. Only 45% of infants achieved iron adequacy, but iron standards were met by most children beyond the age of 1. The main contributors to iron intake were infant/young child formula and baby cereal in children under 4 years, while children over 4 years obtained it primarily from grains (fortified) and meat/fish. Vitamin D was inadequate across all age groups, with the percentage achieving adequacy ranging from 0 to 19% among pre-adolescents and toddlers, respectively. The top sources of vitamin D were fortified milks. Overall, nutrient inadequacies in fiber, calcium, and vitamin D highlight the need for greater intakes of whole grains and fortified dairy products in the UAE.
