Simultaneous determination of tramadol in earwax and urine samples: effects of age, duration time and sex.

Background: This study aims to determine the concentrations of tramadol in earwax (µg/g) and urine (µg/ml) samples taken from postoperative patients, to evaluate the sensitivity of earwax (cerumen) as an alternative analyte and compare it with the findings in urine samples. Results: The results indicated that tramadol concentrations in earwax samples were averaged 45.08 µg/g (range: 13.5-107.7 µg/g), whereas tramadol concentrations in urine samples were averaged 4.97 µg/ml (range: 1.57-10.11 µg/ml). There were significant differences when comparing age groups, duration and sex between earwax and urine samples (p < 0.05). Conclusion: Despite the significant differences between earwax and urine samples, earwax can be used as a bioindicator of tramadol detection.

Evolution of emergency medical services in the Kingdom of Bahrain.

Emergency medical services (EMS) is crucial to any healthcare system, especially in urban countries. The Kingdom of Bahrain has always strived to develop healthcare services throughout the Kingdom including EMS. Like any other country, the Kingdom has gone through several stages in the provision of EMS. This article will focus on the development of EMS in the Kingdom and its evolution from a scattered hospital-based system to a unified system, which ensures ease of access for the population and speed of delivery to the healthcare facilities. The major focus will be the most recent national project which is the National Ambulance.

Vitamin D as potential antidepressant in outpatients with musculoskeletal pain
.

OBJECTIVE: To determine the incidence of vitamin D deficiency, anxiety, and depression disorders in an outpatient population with musculoskeletal pain (MSP), and to evaluate the effects of correcting a vitamin D deficiency on MSP and psychological symptoms. MATERIALS AND METHODS: A total of 261 outpatients with MSP and 100 controls were involved. The Hospital Anxiety and Depression Scale (HADS) was used to assess psychological symptoms. Serum vitamin D was measured. Outpatients with vitamin D insufficiency and deficiency received oral vitamin D supplementation. Pain severity and psychological symptoms were evaluated before and after vitamin D supplementation plus dairy products. RESULTS: Vitamin D deficiency was found in 88.7% of participants in the MSP group and 69% of controls. Clinical anxiety was reported by 38.3% of participants in the MSP group and 9% of controls, while clinical depression was reported by 31.8% of participants in the MSP group and 2% of controls. Multisite pain was significantly and positively associated with anxiety, depression, and pain severity, and was inversely associated with daily calcium intake. Anxiety was inversely associated with vitamin D level, daily calcium intake, and age. A similar pattern was observed for depression. MSP was the most significant independent predictor of anxiety (OR = 7.84) and depression (OR = 5.89). Relative to baseline, all measured outcome parameters significantly improved after vitamin D supplementation plus increased intake of dairy products. CONCLUSION: Low serum vitamin D is associated with MSP along with low calcium intake, depression, and anxiety. Supplementation with vitamin D improved MSP and associated disorders.

Emergency Medicine in the Kingdom of Bahrain.

It has been more than a decade since emergency medicine became recognized as a specialty in the Kingdom of Bahrain. In the last fifteen years emergency medicine has widely established itself and developed rapidly in the Kingdom. The three main emergency departments are: Salmanyia Medical Complex (SMC), Royal Medical Services of Bahrain Defence Force (RMS-BDF) and King Hamad University Hospital (KHUH) are now fully equipped and operated by a majority of board certified emergency physicians.Standardized protocols, and the Central National Ambulance will be established in the near future, and the ambulances will offer both basic and advanced life support by trained nurses and paramedics.Emergency Medicine residency training programs were established in the main three hospitals in Bahrain for the Arab Board Certification initially, while currently only two hospitals, BDF hospital and KHUH are recognized as training centers for the Saudi Board Residency Program.This article will focus on many aspects related to emergency medicine in the Kingdom of Bahrain including: history of health care systems in Bahrain, hospitals and primary care, disaster management, Emergency medical services (EMS), hospital-based emergency care, training in emergency medicine and universities. We aim to present Bahrain's past and existing emergency medicine experience, our perspective about the existing challenges faced by the specialty, and the future plans for the advancement of emergency medicine in the Kingdom.

Vitamin D and PTH status among adolescent and young females with severe dysmenorrhea.

OBJECTIVE: To investigate Vitamin D and parathyroid hormone (PTH) status among adolescent and young females with severe and very severe dysmenorrhea. DESIGN: Cross-sectional study in specific selected sample. SETTING: One Jordanian university. PARTICIPANTS: Fifty-six females, ages between 17 and 24 years, with severe and very severe dysmenorrhea were surveyed regarding demographics, pain with menstruation, and dietary intake of dairy products. Plasma Vitamin D, PTH levels were measured. RESULTS: About 61% of the studied population experience very severe dysmenorrhea. Half of participants had dairy intake less than 1 serving per day. The majority of participants (80%) had insufficient plasma vitamin D and 48% of them had hyperparathyroidism. CONCLUSION: A high prevalence of vitamin D insufficiency and secondary hyperparathyroidism and/or low dietary calcium intake among adolescent and young adult females who experience severe and very severe dysmenorrhea may negatively affect bone metabolism during achievement of peak bone mass at a young age and adverse bone health at older age.

Premenstrual symptoms in dysmenorrheic college students: prevalence and relation to vitamin D and parathyroid hormone levels.

OBJECTIVES: To determine the prevalence of premenstrual symptoms (PMS) due to primary dysmenorrhea among a sample of university female students, and to explore possible association with vitamin D and parathyroid (PTH) levels, as well as frequency of consumption of dairy products. DESIGN: A cross-sectional study. SETTING: One Jordanian university. SUBJECTS: A total of 177 female students aged between 18 and 24 years who experienced primary dysmenorrhea participated in the study and completed a self administered questionnaire to collect information concerning demographics, menstruation-related information, associated specified premenstrual symptoms, and consumption of dairy products. Plasma 25-hydroxyvitamin vitamin D level and intact parathyroid hormone level were measured. RESULTS: Of the 177 participants 91.5% had two or more symptoms among which fatigue, mood swings, anxiety, abdominal bloating, and depression were the most prevalent symptoms. There was no evident association between presence of symptoms and vitamin D status, PTH level or dairy products consumption. Headaches and social withdrawal were significantly lower in those women who consumed high amounts of dairy products. CONCLUSION: Premenstrual symptoms are very common in young women with primary dysmenorrhea. PMS has no relation to levels of vitamin D, parathyroid hormone or dairy products consumption. Headache and social withdrawal may be affected by dairy product consumption.
