Abstract
INTRODUCTION There are limited therapeutic options for individuals with fibromyalgia. The aim of this study is to analyze changes in health-related quality of life and incidence of adverse events of those prescribed cannabis-based medicinal products (CBMPs) for fibromyalgia. METHODS Patients treated with CBMPs for a minimum of 1 month were identified from the UK Medical Cannabis Registry. Primary outcomes were changes in validated patient-reported outcome measures (PROMs). A p-value of <.050 was deemed statistically significant. RESULTS In total, 306 patients with fibromyalgia were included for analysis. There were improvements in global health-related quality of life at 1, 3, 6, and 12 months (p < .0001). The most frequent adverse events were fatigue (n = 75; 24.51%), dry mouth (n = 69; 22.55%), concentration impairment (n = 66; 21.57%), and lethargy (n = 65; 21.24%). CONCLUSION CBMP treatment was associated with improvements in fibromyalgia-specific symptoms, in addition to sleep, anxiety, and health-related quality of life. Those who reported prior cannabis use appeared to have a greater response. CBMPs were generally well-tolerated. These results must be interpreted within the limitations of study design.

Abstract
BACKGROUND The following study evaluated the clinical outcomes of patients enrolled in the UK Medical Cannabis Registry, who were treated with inhaled dried flower (Adven® EMT2, Curaleaf International, Guernsey), and sublingual/oral medium-chain triglyceride-based oils (Adven, Curaleaf International, Guernsey) for chronic pain. METHODS In this cohort study, the primary outcomes were changes in validated patient reported outcome measures (PROMs) at 1, 3, and 6 months compared to baseline, and adverse event analysis. Statistical significance was defined as p < 0.050. RESULTS Three hundred and forty-eight (45.7%), 36 (4.7%), and 377 (49.5%) patients were treated with oils, dried flower, or both, respectively. Patients treated with oils or combination therapy recorded improvements within health-related quality of life, pain, and sleep-specific PROMs at 1, 3, and 6 months (p < 0.050). Patients treated with combination therapy recorded improvements in anxiety-specific PROMs at 1, 3, and 6 months (p < 0.050). 1,273 (167.3%) adverse events were recorded, with previously cannabis naïve users, ex-cannabis users, and females more likely to experience adverse events (p < 0.050). CONCLUSIONS This study observed an association between initiation of CBMP treatment and improved outcomes for chronic pain patients. Prior cannabis use and gender were associated with adverse event incidence. Placebo-controlled trials are still necessary to establish the efficacy and safety of CBMPs for chronic pain.

Abstract
OBJECTIVES To explore pain-specific, general health-related quality of life (HRQoL), and safety outcomes of chronic pain patients prescribed cannabis-based medicinal products (CBMPs). METHODS A case series was performed using patients with chronic pain from the UK Medical Cannabis Registry. Primary outcomes were changes in Brief Pain Inventory short-form (BPI), Short-form McGill Pain Questionnaire-2 (SF-MPQ-2), Visual Analogue Scale-Pain (VAS), General Anxiety Disorder-7 (GAD-7), Sleep Quality Scale (SQS), and EQ-5D-5L, at 1, 3, and 6 months from baseline. Statistical significance was defined at p-value<0.050. RESULTS 190 patients were included. Median initial Δ9-tetrahydrocannabinol and cannabidiol daily doses were 2.0mg (range:0.0-442.0mg) and 20.0mg (range:0.0-188.0mg) respectively. Significant improvements were observed within BPI, SF-MPQ-2, GAD-7, SQS, EQ-5D-5 L index, and VAS measures at all timepoints (p<0.050). Seventy-five adverse events (39.47%) were reported, of which 37 (19.47%) were rated as mild, 23 (12.11%) as moderate, and 14 (7.37%) as severe. Nausea (n=11; 5.8%) was the most frequent adverse event. CONCLUSION An association was identified between patients with chronic pain prescribed CBMPs and improvements in pain-specific and general HRQoL outcomes. Most adverse events were mild to moderate in severity, indicating CBMPs were well tolerated. Inherent limitations of study design limit its overall applicability.

Abstract
Cannabis-based medicinal products (CBMPs) are an emerging therapeutic option in the management of primary chronic pain, using the role of the endocannabinoid system in modulating central and peripheral pain processes. Despite promising preclinical data, there is a paucity of high-quality evidence to support the use of CBMPs for chronic pain. This study aimed to investigate the health-related quality-of-life outcomes of patients with chronic pain who were prescribed CBMP oil preparations (Adven, Curaleaf International, Guernsey, UK). This study is a case series of patients from the UK Medical Cannabis Registry, who were treated with CBMP oils for an indication of chronic pain. The primary outcomes were the changes in Brief Pain Inventory short form, Short-Form McGill Pain Questionnaire-2, Visual Analog Scale Pain, General Anxiety Disorder-7, Sleep Quality Scale, and EQ-5D-5L, at 1, 3, and 6 months. One hundred ten patients were included. Significant improvements in Sleep Quality Scale, EQ-5D-5L pain and discomfort subscale, and Brief Pain Inventory Interference Subscale (P < .05) at 1, 3, and 6 months were demonstrated. There were no notable differences between cannabis-naïve and previous cannabis users in quality-of-life outcomes. The adverse event incidence was 30.0%, with most (n = 58; 92.1%) adverse events being mild or moderate in intensity. Treatment of chronic pain with Adven CBMP oils was associated with an improvement in pain-specific outcomes, health-related quality of life, and self-reported sleep quality. Relative safety was demonstrated over medium-term prescribed use. While these findings must be treated with caution considering the limitations of study design, they can inform future clinical trials.

Abstract
AIM Cannabis-based medicinal products (CBMPs) are prescribed with increased frequency, despite a paucity of high-quality randomized controlled trials. The aim of this study is to analyze the early outcomes of the first series of patients prescribed CBMPs in the UK with respect to effects on health-related quality of life and clinical safety. METHODS A prospective case series was performed using the UK Medical Cannabis Registry. Primary outcomes were change in patient-reported outcomes measures (EQ-5D-5L, General Anxiety Disorder-7 (GAD-7) and Single-Item Sleep Quality Scale (SQS)) at 1 and 3 months from baseline. The secondary outcome was the incidence of adverse events. Statistical significance was defined by a P-value <.050. RESULTS There were 129 patients included in the final analysis with a mean age of 46.23 (±14.51) years. The most common indication was chronic pain of undefined etiology (n = 48; 37.2%). The median initial cannabidiol and (-)-trans-Δ⁹-tetrahydrocannabinol daily dose was 20.0 mg (Range: 0.0-768.0 mg) and 3.9 mg (Range: 0.0-660.0 mg), respectively. Statistically significant improvements in health-related quality of life were demonstrated at 1 and 3 months in GAD-7, SQS, EQ-5D-5L pain and discomfort subscale, EQ-5D-5L anxiety and depression subscale, EQ-VAS and EQ-5D-5L index values(P < .050). There were 31 (24.03%) total reported adverse events. CONCLUSION This study suggests that CBMP therapy may be associated with an improvement in health-related quality-of-life outcomes as self-reported by patients. CBMPs are also demonstrated to be relatively safe in the short to medium-term. These findings must be treated with caution given the limited scope of this initial analysis, with no placebo or an active comparator, with further research required.

Abstract
Abstract
Background: Anthracycline therapy carries a risk for cardiac toxicity in pediatric and adult populations. It is unknown if this risk also applies to fetuses exposed in utero. The objective of this study is to evaluate the cardiac function of neonates exposed to anthracyclines in utero. Materials and Methods: This was an observational study. Pregnant women diagnosed with breast cancer who underwent anthracycline based chemotherapy and delivered a liveborn infant after 24 weeks, were offered enrollment. Patients provided written consent to obtain doses and dates of chemotherapy treatment. Echocardiograms were offered to all newborns exposed as fetuses to anthracyclines. Women chose to perform this echocardiogram locally or at the institution of the primary investigator. Baseline fetal cardiac evaluation was reportedly normal on ultrasound prior to starting chemotherapy.
Chemotherapy Regimens:
Adriamycin/Cytoxan (n=20).
5-Fluorouracil/Adriamycin/Cytoxan (n=3)
There were no cases of exposure to epirubicin or idarubicin.
Mean dosage of Adriamycin was 57/m2 +/−8.0.
Results: Twenty three neonates participated.
Neonatal echocardiograms done at a mean age of 15 +/−26 months, (range 3 days of life to 9.75 years). RV wall, IVS and LV posterior wall diastolic and systolic thickness measurements were within normal limits for age and BSA. Mean shortening fraction was 41+/−10%. (normal 33 +/− 3%). In all 23, AV and semilunar valves were normal. Great arteries were normal in 22/23, with one case of a small pulmonary artery fistula. At 2 years of age, this was not hemodynamically significant. Patent foramen ovale was noted in 4 cases, all in children less than 2.0 months of age. Two children ages 3 days to 1.4 months had a PDA. One child at 1 year of age had an ASD. No structural or functional heart defects were diagnosed in any of these children.
Discussion:
Cardiac function appears to be preserved in neonates exposed to adriamycin chemotherapy in utero.
Any toxic effects on fetal myocytes was not evident in postnatal echocardiograms.

Abstract
Discography is a controversial diagnostic procedure involving the injection of radiographic contrast medium (RCM) into the intervertebral disc. Iatrogenic bacterial discitis is a rare but serious complication. The intervention has been increasingly performed in our patients here in the United Arab Emirates. Prophylactic intravenous antibiotic administration can reduce post-interventional discitis; however, this may favour the development of bacterial resistance. Direct intradiscal injection of an antibiotic together with the RCM is a potential alternative. To date, there has been only one study on the efficacy of antibiotics added to an RCM. Equally, there are only limited data regarding the potential direct effect of RCM on bacterial growth. The purpose of this study was to determine whether the efficacy of antibiotics is affected when RCM are added. In an in vitro study, the effect of non-ionic RCM on the growth of five laboratory bacterial strains, alone and in combination with three broad-spectrum antimicrobials, was tested. Bacterial growth was assessed in the absence and the presence of RCM, antibiotics and their combinations. All three RCM alone demonstrated some inhibition of bacterial growth at high concentrations. In the presence of the RCM, all three antibiotics retained their inhibitory effect on bacterial growth. In conclusion, our in vitro experiments did not reveal any changes in the antimicrobial efficacy of the three antibiotics in the presence of the three tested RCM. Subsequent clinical trials will need to assess whether intradiscal antibiotic administration may be a suitable substitute for, or a supplement to, prophylactic systemic antibiotics before discography.

Abstract
Extended-spectrum beta-lactamase (ESBL) production was demonstrated in five independent, multidrug-resistant isolates of enteroaggregative Escherichia coli (EAEC) from the United Arab Emirates, representing 11.3% of the EAEC isolates recovered during 1 year. All five isolates carried the bla(CTX-M-15) and the bla(TEM-1) genes, the former positioned 48 bp downstream of an ISecp1 element. In two isolates, the bla(CTX-M-15 )and bla(TEM-1) genes were located on a 95-kb plasmid. This is the first detailed description and characterisation of ESBL production in enteroaggregative E. coli and also the first report of CTX-M-producing organisms encountered on the Arabian Peninsula.

Abstract
Recent epidemiologic studies involving Gulf War veterans or agricultural workers suggest that pesticide-pesticide or pesticide-drug interactions may be related to Gulf-War-related illnesses or elevated cancer risks, respectively. Metabolic interactions are one of many potential mechanisms requiring exploration in humans. The goal of the studies is to characterize important metabolic profiles of selected pesticides and examine potential interactions to characterize human risks associated with exposure. Pesticides examined using human liver microsomes and cytosolic fractions included chlorpyrifos, carbaryl and permethrin. The metabolic pathways involved include cytochrome P450 monooxygenases (CYP), esterases, and alcohol and aldehyde dehydrogenases. Specific isoforms and some polymorphic enzymes were characterized. Pesticide-pesticide interactions with metabolizing enzymes were demonstrated. Exposure of human hepatocytes to chlorpyrifos and permethrin demonstrated their potential to induce CYP isoforms using the bDNA (branched deoxyribonucleic acid) assay [used to monitor mRNA (messenger ribonucleic acid) levels]. These studies suggest that knowledge of human metabolic pathways will provide information that can aid the risk assessment process.

Abstract
One hundred and four enterotoxin producing Escherichia coli strains of wide geographical origin were tested for the expression of curli fimbriae by transmission electronmicroscopy and by ELISA using curli-specific antibodies, as well as for the presence of curli-specific gene sequences by PCR. All isolates, irrespective of the production of the fimbriae, carried sequences specific for the structure (csgA) and for one of the regulator genes (crl) of curli expression, respectively. Curli fimbriae were detected in 56 strains (53.8 %). Thirty-six strains expressed curli only when growing at 30 degrees C, 4 isolates were weakly curliated at 37 degrees C only, while on 16 strains curli was observed at both temperatures. On isolates carrying curli at both temperatures the expression of the fimbria was significantly stronger at 30 degrees C than at 37 degrees C. Curli proficiency significantly, but not completely, correlated with the binding of the Congo Red dye. The expression of curli did not confer epithelial cell invasiveness to ETEC strains but, once expressed at 30 degrees C, it facilitated the adherence of the bacteria to plastic surfaces. Curli present in more than half of the ETEC strains and expressed preferentially at low temperatures could be a factor facilitating the environmental survival of this food- and water-borne pathogen.

Abstract
OBJECTIVES (1) To study the prevalence of HEV infection in a cohort of pregnant women in the United Arab Emirates (UAE). (2) The rate of mother-to-infant transmission. METHOD Sera of 469 pregnant women residing in the UAE was tested for anti-HEV with ELISA and for HEV-RNA by polymerase chain reaction (PCR). Neonatal cord-blood and infant blood was similarly tested for anti-HEV and HEV-RNA. Out of these 469 women, 33% were UAE nationals (Group A) and Egyptians (Group B), respectively, and 34% were from the Indian sub-continent (Group C). RESULTS Out of 469 mothers 93 (20%) were anti-HEV positive and 28 (30%) of these 93 were HEV-RNA positive and symptomatic with on-going infection. The prevalence of anti-HEV was significantly increased amongst Groups B and C (Group A:B, P<0.001; Group A:C, P<0.001). Twelve of these 28 symptomatic women developed acute hepatic disease and two died undelivered, thus, were excluded from further study. Six of the remaining 10 women had non-fulminant acute viral hepatitis and four developed fulminant hepatic failure, of which one died in the early post-partum period. The remaining 16 women had mild symptomatic disease with complete recovery as did the remaining nine women with acute illness. Of the 10 babies born to mothers with acute disease, two were pre-term, three had anicteric hepatitis and two babies were born with hypothermia and hypoglycaemia and died within 48h. Noteworthy is the fact that, the 26 infants born to the 26 HEV-RNA positive mothers developed acute/on-going clinical infection and were HEV-RNA positive. Apart from the two early neonatal deaths, the remaining 24 infants had full recovery. No infant of the other mothers were symptomatic or had HEV-RNA. Thus, the mother-to-infant transmission was 100%. The remaining 65 sero-positive women remained asymptomatic with no evidence of clinical infection, continued to be HEV-RNA negative and delivered at term. Their infants had no evidence of infection and were sero-negative by 9 months of age, suggesting transplacental transmission of IgG antibodies. CONCLUSIONS There is a high prevalence of anti-HEV among pregnant women residing in the UAE. Twelve of infected women developed fulminant/acute hepatitis resulting in three fatalities. Evidence suggests significant vertical transmission of HEV among HEV-RNA positive mothers with appreciable perinatal morbidity and mortality. Excluding mothers with acute hepatic disease, Breast-feeding appears to be safe in HEV sero-positive mothers.

Abstract
A retrospective epidemiological analysis was performed of Mycobacterium tuberculosis infections in the Al Ain Medical District, Al Ain, United Arab Emirates (U.A.E.) during the period 1995-2000. The mean incidence for the study period was 7.1%, more than 3 times that reported for the period 1983-1992 (2.1%). For the years 1997 through 2000, the highest incidences (approximately 5-7% of tested) were from health care facilities that cater exclusively for citizens and long-term residents of the U.A.E. Corresponding rates for the immigrant visa applicants (non-citizens) were lower and showed a dramatic decrease from approximately 18% in 1995 to approximately 2% in 2000. Most importantly, the number of multidrug-resistant cases showed an increase from 1.4% during the period August 1997-December 1998 to 8.5% during the period January 1999-July 2000. Analysis of 7 different isolates by restriction fragment length polymorphism (RFLP) showed RFLP patterns that did not match > 4000 individual patterns from 32 countries, suggesting the possible presence of M. tuberculosis strains unique to the U.A.E. Our data demonstrate local transmission of M. tuberculosis in the Al Ain Medical Region of the U.A.E.

Abstract
Morphea is an inflammatory cutaneous disease that can be mistaken for a soft-tissue neoplasm. The authors report two cases of morphea that were resected surgically before the histological diagnosis of morphea was rendered. One of the patients had a recurrence of morphea around her large surgical scar. They present these cases to alert surgeons to the pitfall of inappropriate surgical treatment of an inflammatory condition.

Abstract
Ophthalmia neonatorum in small babies is a common problem in neonatal units in Al Ain, but is infrequently associated with sexually transmitted disease agents. A study of 81 babies with ophthalmia neonatorum showed that 81.5% had bacterial or fungal infections. Staphylococcus aureus was the commonest causative organism followed by Escherichia coli and Pseudomonas aeruginosa while Chlamydia trachomatis and Neisseria gonorrhoeae were responsible for less than 5% of all cases. The disease was predominantly mild to moderately severe and easily treated with topical broad-spectrum antibiotic agents which are effective against Gram-positive and Gram-negative bacteria, including hospital-associated strains. The most effective antimicrobial agents were gentamicin topically or ceftriaxone systemically.
