Iron Deficiency Anemia in Pregnancy: Novel Approaches for an Old Problem
Simone Garzon, Patrizia Maria Cacciato, Camilla Certelli, Calogero Salvaggio, Maria Magliarditi, Gianluca Rizzo
Iron needs increase exponentially during pregnancy to meet the increased demands of the fetoplacental unit, to expand maternal erythrocyte mass, and to compensate for iron loss at delivery. In more than 80% of countries in the world, the prevalence of anemia in pregnancy is > 20% and could be considered a major public health problem. The global prevalence of anemia in pregnancy is estimated to be approximately 41.8%. Undiagnosed and untreated iron deficiency anemia (IDA) can have a great impact on maternal and fetal health. Indeed, chronic iron deficiency can affect the general wellbeing of the mother and leads to fatigue and reduced working capacity. Given the significant adverse impact on maternal-fetal outcomes, early recognition and treatment of this clinical condition is fundamental. Therefore, the laboratory assays are recommended from the first trimester to evaluate the iron status. Oral iron supplementation is the first line of treatment in cases of mild anemia. However, considering the numerous gastrointestinal side effects that often lead to poor compliance, other therapeutic strategies should be evaluated. This review aims to provide an overview of the current evidence about the management of IDA in pregnancy and available treatment options.

Medical Liability of Healthcare Professionals Under Omani Law: A Primer
Nasser Hammad Al-Azri
Professionals in healthcare face, not infrequently, medical liability issues in their practice. Worldwide, patient safety has become a major medical, legal, ethical, political, and economic concern. Oman has witnessed a leap in its medical and legal spheres over the last half a century. Developments in healthcare services in the country have taken place in parallel with developments in legal awareness regarding patient safety and bodily integrity. However, many healthcare practitioners remain unaware of medical liability essentials in their daily practice. Neither basic medical education nor professional development education incorporates medical law in general and, specifically, medical liability in their courses and curricula. Hence, this article attempts to present the essentials of medical liability in healthcare practice in accordance with existing Omani legislation. It defines medical liability and identifies four types of liability that healthcare practitioners might be prone to penal, civil, disciplinary, and administrative liabilities. Each of these forms of liability is discussed with examples illustrating it from enacted Omani laws. This paper concludes by recommending a further focus on medical law in basic and professional education of healthcare practitioners in Oman.

Determinants and Prevention Strategies of Substance Abuse in Pacific Countries: A Systematic Review
Masoud Mohammadnezhad, Anjali Thomas, Russell Kabir
Objectives: People abuse substances like drugs, alcohol, and tobacco for different reasons, including pleasure, improved performance and vigilance, relief of depression, curbing hunger, and weight control. In this review, we sought to identify the determinants and prevention strategies that have been undertaken to minimize the issue of substance abuse. Methods: The systematic review was conducted following the Cochrane Library Guidelines and PRISMA checklist. We searched six online databases to identify studies from January 2000 to July 2017. Results: Only peer-reviewed studies published in the English language that had full text accessible were included. We reviewed 19 studies; only one was quasi-experimental and the majority were descriptive studies. The determinants of substance abuse identified include personal, faciliatory/promotor, environmental, and social factors. The prevention strategies identified use culturally appropriate and gender-sensitive treatments, and identify sources of strength in families, community, individual, and even spiritual. Conclusions: Substance abuse poses significant public health risks and therefore requires adequate interventions such as educating and informing individuals of the health risks associated with substance abuse and must be considered locally to promote the well-being of people.

Local Usage of Nigella sativa Oil as an Innovative Method to Attenuate Primary Dysmenorrhea: A Randomized Double-blind Clinical Trial
Ezat Samadipour, Mohammad Hassan Rakhshani, Akram Kooshki, Bahareh Amin
Objectives: We sought to determine the effect of topical application of Nigella sativa (black seed) oil, on the primary dysmenorrhea intensity. Methods: We conducted a randomized, double-blind clinical trial on 124 female students, 18–22 years old, living in the dormitories of Sabzevar Universities. After a primary assessment, participants were randomly divided into two groups. The first group rubbed two drops of N. sativa oil, and the second group rubbed liquid olive oil, as the placebo. Massage was performed on the fontanel lobe 3, at night, three days before menstruation, for eight consecutive days (about five days after menses). This procedure was repeated for three menstrual cycles. After three cycles, pain severity was measured by the visual analog scale. Data analysis was carried out using the Mann-Whitney U test and analysis of covariance (ANCOVA). Results: This study was conducted on 124 female students. The mean age of students, mean age of first menarche, body mass index, and pain severity were not significantly different in the two groups (p > 0.050). No adverse effects were observed during the study. The results of ANCOVA showed that pain intensity in N. sativa oil group was significantly decreased compared to that of the placebo group (0.6 score; p < 0.050). Conclusions: N. sativa could be a promising, safe, and easily available analgesic supplement in women suffering from primary dysmenorrhea.

Modulation of Interleukin-8 Production by Vitamin D Supplementation in Indonesian Patients with Diabetic Polyneuropathy: A Randomized Clinical Trial
Aida Fitri, Hasan Sjahrir, Adang Bachtiar, Muhammad Ichwan
Objectives: We sought to assess the modulation of interleukin-8 (IL-8) production by vitamin D supplementation in Indonesian patients with diabetic polyneuropathy (DPN). Methods: We conducted a cohort prospective, randomized, placebo-controlled, double-blind trial. This study was approved by the Local Ethical Committee and conducted from July 2018 to February 2019. We recruited 50 subjects with type 2 diabetes mellitus attending Haji Adam Malik General Hospital Medan, and divided them into two groups. The groups were treated for 10 weeks, either with placebo or vitamin D (D3) supplementation of 50 000 IU/week. They were evaluated by routine nerve conduction study (NCS) in the upper and lower limbs, and their serum vitamin 25-hydroxyvitamin D (25(OH)D) and IL-8 levels before and 10 weeks after placebo or vitamin D supplementation were measured. The role of IL-8 and vitamin D supplementation on the NCS was analyzed using linear regression. Results: There was a significant difference between the mean vitamin 25(OH)D (p = 0.001) and IL-8 levels (p = 0.002) before and after vitamin D supplementation. There was no significant correlation between changes in vitamin 25(OH)D and IL-8 levels (p = 0.743). There was significant role of IL-8 on amplitude of the sensory sural nerve (p = 0.047; B = -0.009) and the nerve conduction velocity (NCV) of the motor tibial nerve (p = 0.007; B = -0.027). There was a significant role of vitamin D supplementation on NCSs. Conclusions: Higher IL-8 levels were correlated with poorer amplitude of the sensory sural nerve and the NCV of motor tibial nerves. Lower vitamin 25(OH)D levels were correlated with poorer distal latencies, amplitudes, and NCVs. There was no significant correlation between vitamin 25(OH)D and IL-8 levels. Thus, no sufficient evidence that vitamin D supplementation modulates IL–8 in Indonesian patients with DPN. Vitamin D3 improved NCSs in diabetic patients.

Bader A. Alqahtani, Aqeel M. Alenazi
Objectives: The purpose of the study was to cross-culturally adapt the Rapid Assessment of Physical Activity (RAPA) for Arabic speaking people and examine the test-retest reliability and the construct validity in Saudi older adults. Methods: Test-retest reliability was assessed over two testing visits occurring one week apart. The construct validity was examined between RAPA and Short Physical Performance Battery (SPPB) and Timed Up and Go (TUG) tests. Results: The original RAPA was translated into Arabic following standardized guidelines. For the test-retest reliability, the weighted kappa was 0.87 (95% confidence interval: 0.76–0.98), which indicates good reliability. There was a significant correlation between the Arabic version of RAPA and the SPPB (Spearman’s correlation coefficients (r) = 0.536, p < 0.001), and the TUG test (r = -0.435, p < 0.010). Conclusions: The Arabic version of the RAPA questionnaire adapted for Saudi older adults provides an easy, valid, and reliable way to measure physical activity.

Demographic Features and Etiology of Congenital Hypothyroidism at the National Diabetes and Endocrine Center in Oman from 2004 to 2016
Mohammed Al Jafari, Sachin Jose, Aisha Al Senani
Objectives: Congenital hypothyroidism (CH) is the most common endocrine disorder in neonates as well as one of the few preventable causes of severe learning difficulties. Early screening, diagnosis, and treatment are mandatory to prevent later sequelae. We sought to determine the demographic and the clinical features of CH in Oman. Methods: We conducted a retrospective cross-sectional study, including all Omani children newly diagnosed with CH from January 2004 to December 2016 followed at the National Diabetes and Endocrine Center at the Royal Hospital. Those with transient hypothyroidism were excluded from the study. Data collection involved demographic data, clinical manifestations, lab investigations, thyroid scan results, and initiation date of the thyroxine (T4). Results: A total of 96 patients were newly diagnosed with CH during the study period. Out of the 96 patients, 43 were males (44.8%), and 53 were females (55.2%), and majority were asymptotic (n = 84; 87.5%). Only 78 patients had a thyroid scan. Among those who did the scan, thyroid dysgenesis was the most common (n = 40, 51.3%), followed by dyshormonogenesis (n = 35; 44.9%) and the least was central hypothyroidism (n = 3; 3.8%). The majority of patients (n = 72; 86.7%) were started on T4 therapy within 30 days of life. The remaining (n = 11; 13.3%) had a delay in starting the treatment due to compliance issues, which led to a developmental delay (p < 0.001). Conclusions: This is the first epidemiological study conducted in Oman that highlights the unique demographic and etiology features of CH. Dyshormonogenesis has a high prevalence in the Omani population compared to other nations. The neurological sequelae in our patients were higher in compression to worldwide prevalence, which was mainly due to delay in starting T4 therapy.

Khaled Al Dahmani, Bachar Afandi, Ali Elhouni, Denish Dinwal, Jim Philip, Alaaeldin Bashier, Salem A Beshyah, Nico Nagelkerke, Juma M. Alkaabi
Objectives: We sought to ascertain the clinical characteristics and control rate of acromegaly in the UAE. Methods: We conducted a multicenter retrospective analysis of all patients presenting with acromegaly to six endocrine centers in the UAE between November 2010 and December 2018. Demographic, clinical, biochemical, and radiologic data were collected. Patients were considered controlled if normal insulin-like growth factor-1 (IGF-1) level and growth hormone < 1 mcg/L were achieved at their last visit. Results: A total of 75 patients were included in the study (60.0% males, 33.3% native UAE nationals). The mean age at diagnosis was 37.2 (range: 12–69) years. Common clinical features at diagnosis were headache (82.4%), coarse facial features (82.4%), acral enlargement (79.7%), and sweating (31.3%). Diabetes mellitus/prediabetes and hypertension were present in 45.2% and 35.5% of patients, respectively. About 82.2% had pituitary macroadenoma on pituitary magnetic resonance imaging. At presentation, 27.0% and 3.2% of the patients had secondary hypogonadism and diabetes insipidus, respectively. Overall, 76.7% of the patients underwent surgery, 20.8% received radiotherapy, and 50.7% received medical therapy. At their last clinic visit, only 43.7% of all patients achieved disease control. Conclusions: Our study shows a high prevalence of pituitary macroadenoma in our acromegalic population, suggesting a delayed diagnosis. Also, a significant proportion of patients remained uncontrolled. Efforts to increase physician’s awareness of acromegaly and to improve disease control are underway.

Family Functional-based Coaching Program on Healthy Behavior for Glycemic Control among Indonesian Communities: A Quasi-experimental Study
Rian Adi Pamungkas, Kanittha Chamroonsawasdi
Objectives: This study sought to examine the impact of a family functional-based coaching program on improving the perceived family functioning practice and clinical outcomes among patients with glycemic uncontrolled type 2 diabetes mellitus (T2DM) in the Indonesian community. Methods: We applied a quasi-experimental study, pretest, and posttest design with a non-equivalent control group. Sixty pairs of T2DM patient-caretaker dyads were recruited and assigned to either an intervention or control group. The Family Function Questionnaire (FFQ) was used to assess the perception of family functioning practices by T2DM patients of their caretakers to support their diabetes self-management. The clinical outcomes were measured using clinical outcome devices and laboratory tests. These measurements were conducted and compared at a baseline and 12 weeks after completing the program. Results: Patients who received the family functional-based coaching program saw significant improvement in perception of family function practice, compared to the control group who received usual care. The findings also showed a positive decline glycated hemoglobin and total cholesterol levels after receiving the 12-week program. However, no significant difference was found in body mass index. Conclusions: It can be concluded that a family functional-based coaching program is feasible to implement among uncontrolled T2DM in a large scale study.

Academic Adjustment, Emotional Intelligence, and Fear of Missing Out among Undergraduate Students: A Descriptive Correlational Study
Mohammed Ghalib Mosa Qutishat
Objectives: Fear of missing out (FOMO) is the tendency of individuals to remain connected and updated with what others behave and think. During their academic life, students may find themselves disconnected from real social interactions and wish for a unique platform of social support. This study aimed to investigate the relationship between FOMO, academic adjustment (AD), and emotional intelligence (EI). Methods: The study adopted a descriptive correlational design. The total sample size was 339 based on defined inclusion criteria. The questionnaires were distributed over one month during the 2019 summer semester by the research team at the Sultan Qaboos University colleges. The study used a self-reported instrument as a measurement tool to investigate the extents of the research phenomena, consisting of three major sections: the FOMO Questionnaire, EI Questionnaire, and the AD Scale. Results: The mean age of the participants was 21.5 years. The majority were single (93.5%), lived off-campus (56.0%), in their fifth academic year (33.9%), and had a GPA grade B (48.1%). The participants displayed mild FOMO, AD, and EI rates. The findings demonstrated significant gender differences between research participants in FOMO and EI. They also showed substantial experiences of FOMO among different living arrangements. This study also postulated that EI and AD in students who are feeling a high degree of FOMO were substantially higher. Conclusions: Further researches and strategies should be developed to help students control the technology they use so they can be utilized effectively for the right purposes.

Objectives: We sought to assess the prevalence of hepatitis B virus (HBV) seroprotection among vaccinated children in the Assiut governorate, Egypt, and assess a booster dose immune memory response among non-seroprotected children. Methods: Using a multistage cluster sample, 566 children were recruited from three clusters: one urban and two rural. Children were aged from nine months to 16 years old. All participants received the full three doses of the compulsory HBV vaccine during infancy. Serum hepatitis B surface antigen (HBsAg), total anti-hepatitis B core (anti-HBc) antibodies, and quantitative detection of anti-HBs were measured using enzyme-linked immunosorbent assay. Repeatedly positive samples for HBsAg/anti-HBc were submitted for quantitative HBV DNA detection using real-time polymerase chain reaction. Non-seroprotective participants (anti-HBs < 10 IU/L) were given a booster dose of HBV vaccine. Two weeks later, a blood sample was taken from each child to assess an anamnestic response. Results: The seroprotection rate was 53.2%, and only two children had HBV breakthrough infection (0.4%) with positive serum anti-HBc and HBV DNA. Age was the only significant predictor for non-seroprotection with an adjusted odds ratio (OR) of 3.2, 9.4, and 9.9 among children aged 5–10, 11–15, and > 15 years, respectively, compared to younger children (p < 0.001). About 85% of non-seroprotected children developed an anamnestic response after receiving the booster dose, and 84.3% of responders had a good response (≥ 100 IU/L). Undetectable pre-booster titer was found to be the only risk factor for non-response to booster with OR = 3.2 (p < 0.010). About 95.7% of children who were not responding to booster dose developed immune response after receiving the three doses of HBV vaccine. Conclusions: Older age of children was the only significant predictor for HBV non-seroprotection. High anamnestic response rate signifies the presence of immune memory with long-term protection despite the waning of anti-HBs over time. However, some children with pre-booster undetectable anti-HBs titers may be unable to develop anamnestic response, and a second vaccination series might be necessary for HBV protection for these children.

Prevalence of Red Blood Cell Alloimmunization among Transfused Chronic Kidney Disease Patients in Hospital Universiti Sains Malaysia
Shafini Mohamed Yusoff, Rosnah Bahar, Mohd Nazri Hassan, Noor Haslina Mohd Noor, Marini Ramli, Nor Fadhilah Shafii
Objectives: Red blood cell (RBC) immunization is a common complication in blood transfusion recipients. Patients with chronic kidney disease (CKD) eventually develop anemia, which is multifactorial, and requires regular blood transfusions, which exposes patients to the development of RBC antibodies. We sought to determine the prevalence and specificity patterns of RBC immunization and its risk factors among transfused CKD patients. Methods: We conducted a cross-sectional study over one year from January to December 2018 in the Transfusion Medicine Unit, Hospital Universiti Sains Malaysia. A total of 249 samples were recruited from CKD patients who received a blood transfusion (at least one-pint), which only match for ABO and Rh(D) antigen. The serum was screened for the presence of the RBC antibody using the gel agglutination technique (Diamed gel cards). Samples with positive antibody screening were subjected to antibody identification. Results: Of the 249 transfused CKD patients, 31 (12.4%) developed RBC immunization. Thirty (12%) were alloimmunized, and one (0.4%) was autoimmunized. Anti-Mia was the most common antibody (n = 14, 46.7%) among alloantibodies, followed by anti-E (n = 7, 23.3%). There was a significant association between pregnancy history with the development of antibodies whereas, no significant association was found between sociodemographic background, stage of CKD, hemodialysis status, underlying medical illness, and number of packed cell transfusions with the development of RBC antibodies. Conclusions: One-eighth of our patient cohort had RBC alloimmunization, and the risk was increased in patients with a history of pregnancy. We propose Rhesus RBC phenotyping and to supply blood match Rhesus antigen in CKD patients, especially patients of reproductive age.

Renal Epithelioid Angiomyolipoma: A Case Report and Review of Literature
Rashid Al Umairi, Ruqaiya Al Shamsi, Atheel Kamona, Fatma Al Lawati, Sadiq Abdul Baqi, Geroge Kurian, Jokha Al Kalbani
Epithelioid angiomyolipoma (EAML) is an uncommon renal neoplasm with malignant potential. It is classified under the group of perivascular epithelioid cell tumors and can be sporadic or as part of the tuberous sclerosis complex. On imaging, unlike classical AML that contains fat, EAML has a very low percentage of fat which can mimic the imaging findings of renal cell carcinoma. We reported a 31-year-old female who had a history of renal failure and bilateral renal masses. Magnetic resonance imaging of the abdomen revealed bilateral large renal masses replacing renal parenchyma with features suggestive of bilateral renal AML. The patient underwent left nephrectomy, and histopathology examination findings were consistent with the diagnosis of EAML.

Anabolic Steroid Use and Aortic Dissection in Athletes: A Case Series
Aghigh Heydari, Atefeh Asadmobini, Feridoun Sabzi
The use of anabolic steroids in supraphysiologic doses has grown in the last decade as doping drugs in athletes. The high dose of anabolic-androgenic steroids (AAS) causes cardiomyopathy, hypertension, thrombosis, myocardial infarction (MI), weakness of connective tissue, and its sequelae such as tendon injury and aortic dissection. Dissection of the ascending aorta is an uncommon injury that has been recognized with increasing frequency in bodybuilders in recent years. It has been proposed that such cases commonly accompany the weakening of connective tissue and must be actively evaluated in the presence of anabolic steroid usage. We present a case series of isolated ascending aorta dissection in athletes who were bodybuilders. All cases were evaluated by transthoracic echocardiography (TTE) and laboratory exams. These cases also served as a reminder of the risks of ascending aorta dissection with AAS, especially in strength athletes who place high demands on their musculoskeletal structures. The results of the current study suggested that anabolic steroid abuse may be associated with detrimental effects on the myocardium represented as cardiomyopathy or atherosclerotic changes in the coronary artery as MI. These findings also strongly suggest that anabolic steroid treatment predisposes the individual to aortic dissection, especially when the patients are exercised.

Hanaa A. AlAraimi, Khalid Al-Alawi, Amina K. Al-Jardani, George Paul, Nashat Al-Sukaiti, Abdullah Al-Farqani, Amal S. Al-Maani
Q fever endocarditis is the most common presentation of chronic infection of Coxiella burnetii, but it rarely occurs in the pediatric age group. We report the first case of Q fever endocarditis in an Omani child. The affected 11-year-old female lives in the Al Batinah governorate in the north of Oman and was known to have congenital heart disease. She presented with features of chronic blood culture-negative endocarditis. The C. burnetii infection was confirmed with the indirect immunofluorescence assay. The patient responded well to a combination of doxycycline and hydroxychloroquine therapy.

Imaging of Pharyngocele: An Occupational Overuse Syndrome
Dillibabu Ethiraj, Suresh D. Kumar, Venkatraman Indiran, Prabakaran Maduraimuthu
Pharyngocele is a rare pathology of the pharynx caused by the laxity of the thyrohyoid membrane. Only about 60 true lateral pharyngocele cases have been reported in the literature over the last 133 years. Laryngocele is a close differential, and the two are difficult to tell apart. Though they have been described well in the literature, they are often misdiagnosed or interchangeably diagnosed. The acquired type of pharyngocele is due to prolonged increased intrapharyngeal pressure and pharyngeal wall weakness, and it is more common than congenital pharyngoceles. Close differential diagnoses include Zenker’s diverticulum, laryngocele, and jugular venous phlebectasia. Acquired lateral pharyngoceles are seen in wind instrument musicians and glassblowers. Hence, these diverticula are described as ‘overuse syndrome’. We present a case of bilateral neck swelling, which occurred doing the Valsalva maneuver with imaging studies.
Keywords: Pharynx; Diverticulum; Radiology; Neck.
