Association of Acanthosis nigricans with risk of diabetes mellitus and hormonal disturbances in females.

OBJECTIVE: To determine the association of Acanthosis nigricans, hyperinsulinemia, and hormonal levels in female subjects from the United Arab Emirates (UAE). DESIGN: Prospective study. SETTING: Tawam Teaching Hospital of Faculty of Medicine & Health Sciences. SUBJECTS: Ninety-two females (age range 16-65 years) were recruited. METHODS: Height, weight, and sitting blood pressure were recorded on 92 female subjects with A. nigricans. Fasting blood samples were obtained for measurement of uric acid, glucose, cholesterol, high-density lipoprotein- (HDL) cholesterol, and triglyceride levels. Serum levels of thyroid stimulating hormone (TSH), testosterone, luteinizing hormone (LH), follicle-stimulating hormone (FSH) and prolactin are obtained by radio-immunoassay. RESULTS: Ninety-two females with A. nigricans were enrolled in the study. Of the 92 females, 36 subjects were considered to have diabetes mellitus (DM) and 56 euglycemic subjects. The analysis showed that in cases of family history of DM, HDL-cholesterol (mmol/l) and uric acid (mmol/l) levels were higher. Overall, DM subjects had significantly higher values for hormone levels of TSH, FSH, LH, progesterone, testosterone, cortisol, prolactin, (growth hormone) GH, and ferritin. CONCLUSION: Patients with A. nigricans have a high prevalence of DM and insulin resistance in UAE. Since A. nigricans is rather prevalent in the UAE, identifying this skin lesion can help detect those subjects with a higher risk of DM and hormonal disturbances.

Genetic and environmental factors associated with migraine in schoolchildren.

OBJECTIVE: The aim of this study was to find the prevalence of migraine and headache in schoolchildren in the United Arab Emirates and to determine the genetic and environmental factors associated with these conditions. METHODS: A cross-sectional population study was performed from October 1995 to June 1996. Subjects were selected by a multistage stratified sampling procedure. Data were collected by screening questionnaires followed by clinical interviews. Twelve primary schools and 1400 schoolchildren of United Arab Emirates nationality resident in the Al Ain City, Dubai, and Sharjah emirates were recruited for this study. A total of 1159 (82.7%) schoolchildren gave their consent to the study. RESULTS: The estimated prevalence rates for headache and migraine were 36.9% and 13.7%, respectively. The prevalence of headache is increased with age, the highest prevalence being in 13-year-old children (17.5%). Of the 159 children who fulfilled the diagnostic criteria for migraine, 76 were boys whose mean age (+/- SD) was 10.3 years +/- 2. 8 years, and 83 were girls (mean age 9.9 +/- 2.5 years). Of the children who had migraine, 20 (12.6%) had migraine without aura, and 13 (8.2%) had migraine with aura. The most common migraine symptoms in schoolchildren had been aggravated by physical activity (47.2%) and a positive family history of migraine (46.5%). The most common illnesses were infectious illnesses (41.5%). There was a strong relationship between migraine and the timing of examinations (46.5%). The most common environmental exposure for migraine was found to be playing on a computer (45.9%), followed by loud noise (41.5%), and a hot climate (37.1%). In familial occurrence of headache among immediate relatives, the most frequently affected relative was the mother (17.6%). CONCLUSION: .-Headache and migraine are common in childhood and may be influenced by social, familial, environmental, and psychological factors.

Haemophilus influenzae type b still remains a leading cause of meningitis among unvaccinated children--a prospective CSF analysis study.

A prospective, hospital-based cerebrospinal fluid (CSF) analysis study was undertaken in 65 children who had diagnostic lumbar puncture on admission for suspected central nervous system infections. Twenty-three children were clinically diagnosed to have had sepsis and/or meningitis. CSF bacterial culture grew Haemophilus influenzae type b (Hib) in four cases and Streptococcus pneumonia (SP) was cultured in another child. Bacterial antigen was detected in 13 other CSF specimens and the pathogens were Hib (n = 9), SP (n = 3) and Group B Streptococcus (n = 1). No etiologic cause was identified to explain the abnormal CSF pleocytosis and biochemistry in the remaining five cases. In contrast, the CSF analysis was normal in 42 other children with probable viral and non-infectious neurological condition, mostly febrile convulsions. The overall frequency rate for all types of meningitis and especially for Hib meningitis were 43 and 31 cases per 100,000 children < 5 years of age, respectively. These findings support our earlier observations that Hib meningitis still remains the leading cause of childhood meningitis in our region. Also it reaffirms the observation that bacterial meningitis may often be under-reported if CSF positive culture alone is considered for the diagnosis.

A prospective comparative analysis of mobility in osteoarthritic knees.

We have sought to clarify whether the traditional Arabic lifestyle prevents restriction of movement in patients with degenerative arthritis of the knee. The range of movement of 68 osteoarthritic knees of Arabic patients was compared with that of 51 healthy knees of Muslim patients and 83 osteoarthritic knees in non-Arabic patients. The range of flexion of the osteoarthritic knees in the Arabic patients matched that of the healthy control knees, but was significantly better than that of the osteoarthritic knees in the non-Arabic patients. There was also a statistically significant difference between the mean extension deficit of the two groups with osteoarthritis. Exercises may help to prevent restriction of movement in osteoarthritis of the knee.

Measurement-specific quality-of-life satisfaction during the menopause in an Arabian Gulf country.

OBJECTIVE: The aim of this study was to use an instrument, the menopause-specific quality-of-life satisfaction questionnaire for the postmenopausal period, in the United Arab Emirates (UAE). DESIGN: A cross-sectional descriptive study was used to generate menopause symptoms experienced by Arabian Gulf women. Measurement-specific quality-of-life satisfaction questionnaires were used and face-to-face interviews were performed. SETTING: The study was based in primary health-care clinics in Al Ain City, Sharjah and Dubai Emirates, UAE. SUBJECTS: A multistage sampling design was used, and a representative sample of 450 UAE females aged 45 years and above were included during January-April 1999. RESULTS: Of the 450 women living in both urban and rural areas, 390 women agreed to participate (86.7%) and responded to the study. The mean age and standard deviation (SD) of the subjects was 56.5 +/- 6.6 years, and the median age of natural menopause in the present study was 48 years (mean +/- SD 48.4 +/- 3.8). The rate of consanguinous marriages in the sample was found to be 47.2%. The most common disease was found to be diabetes mellitus (10.3%), followed by osteoarthritis (7.7%), hypertension (7.2%) and asthma (6.2%), but the majority of subjects (68.7%) had no specific disease. Out of 29 possible symptoms, the mean number of symptoms was 7.57 (range 0-24). The most frequent symptom was 'aches in the back of the neck or head' at 46.4% followed by 'aches in the muscles/joints' at 34.6%. The least reported symptom was 'facial hair' at 15.9%. Increasing education resulted in more symptoms reported, and increasing parity resulted in fewer symptoms reported. In the present study, it was found that employed women experienced more symptoms and disorders. Of the total sample, 28.5% of the subjects reported no symptoms. In the four domains, 69% reported physical symptoms, 58.7% reported psychosocial symptoms, 40% reported vasomotor symptoms and 37.9% reported sexual symptoms. Spearman's rank correlation coefficient indicated that there is highly statistically significant concordance between the four domains (p < 0.01). CONCLUSION: The present study showed that menopause-related symptoms in UAE women are fewer and of less severity than in Western women. The postmenopausal women, despite a continued decline in estrogen levels, reported few symptoms as part of a normal life stage, suggesting that they were able to cope with stress.

Asthma and respiratory symptoms among school children in United Arab Emirates.

OBJECTIVES: To determine the prevalence of asthma, wheezing, hay fever, and eczema among primary school children aged 6-13 years in United Arab Emirates (UAE). DESIGN: A cross-sectional study on school children was performed using the International Study of Asthma and Allergies in Childhood (ISAAC) questionnaires. SETTING: Government primary school children in seven Emirates, in UAE. SUBJECTS: Subjects were selected by a multi-stage stratified sampling design. 4200 children targeted for this study, but only 3200 children aged 6-13 years were agreed to participate and responded to the study. The overall response rate was 69.8%. RESULTS: The prevalence of physician diagnosed asthma was 13%, in addition, the wheeze by history was 15.6%. Furthermore, the prevalence of nocturnal cough was 21%. On the other hand, the prevalence of eczema was 11% and hay fever was 14.9%. Parental asthma but not parental atopy was associated with an increased risk of asthma and wheezing in children. CONCLUSIONS: The prevalence of asthma and wheezing in UAE is consistent with that in neighbouring Gulf countries.

Somatized mental disorder among primary care Arab patients: I. Prevalence and clinical and sociodemographic characteristics.

The aims of this study were to estimate the prevalence of somatized mental disorder (SMD) in comparison to psychologized mental disorder (PMD) among a sample of primary health care (PHC) Arab patients, and to investigate the clinical and sociodemographic characteristics of SMD. The first stage of study was conducted by general practitioners (GPs), using the 12-item General Health Questionnaire (GHQ-12). The second stage was carried out by a psychiatrist using the Clinical Interview Schedule (CIS) and an inquiry schedule. Specific operational criteria were used to identify SMD and PMD. The estimated prevalence rate of SMD among the total screened sample was 12%. SMD patients constituted 48% of the psychiatric patients identified, whereas, for the PMD group, this figure was 42%. Educational level was significantly lower in the SMD group. Headache, backache, and abdominal pain were the most commonly presented somatic symptoms. The symptoms pursued a chronic and persistent course and most patients experienced multiple symptoms. The most common ICD-10 psychiatric diagnoses among both SMD and PMD patients were mixed anxiety and depressive disorder, generalized anxiety disorder, and mood and adjustment disorders. Recurrent depressive disorder and dysthymia were significantly more prevalent in the PMD group. The severity of psychiatric illness identified was greater among psychologizers than the somatizers of mental disorder.

Pattern of central nervous system anomalies in a population with a high rate of consanguineous marriages.

Nine thousand six hundred and ten births were prospectively studied in the three major hospitals in Al-Ain, United Arab Emirates (UAE) between October 1995 and January 1997. Babies suspected of, or diagnosed, as having central nervous system (CNS) abnormalities were evaluated by a neonatologist, a clinical geneticist and a pediatric neurologist. Brain computerized tomography/magnetic resonance imaging (CT/MRI) was performed on all babies suspected of having CNS abnormalities. In addition, metabolic screening and chromosome analysis were also performed when indicated. Of the 225 babies with congenital anomalies identified, 31 had CNS abnormalities (3.2/1000). Syndromic abnormalities of the CNS were present in 13 cases (42%), chromosomal abnormalities in one case (3.2%) and the rest included: neural tube defect (NTD) in 11 cases (36%), holoprosencephaly in two cases (6.4%) and hydrocephalus in four cases (12.9%). Detailed analysis of the syndromic types revealed that out of the 13 cases, 12 were inherited as autosomal recessive (AR) and in one case the inheritance was undetermined. Consanguinity with high level of inbreeding was present in 12 cases and the majority of the syndromes identified were extremely rare. The study indicates that CNS anomalies are fairly common in the UAE, particularly, the recessive syndromic types. Careful and detailed analysis of such anomalies is required so that accurate genetic advice can be given.

Allergic contact dermatitis in the United Arab Emirates.

BACKGROUND: No data exist on allergic contact dermatitis (ACD) in the United Arab Emirates (UAE). AIM: Our aim was threefold: (i) to determine the incidence of ACD; (ii) to identify responsible allergens using the European Standard Series, TRUE TEST, and other substances; (iii) to tentatively explore population-specific reactions in Al Ain, UAE. DESIGN: This is a prospective, descriptive, hospital-based, study. SETTING: Tawam Hospital, Al Ain Medical District, UAE. PATIENTS: During the years 1989-1996, 373 patients (male: female = 2 : 3), presenting with cutaneous manifestations possibly related to contact allergy, were patch tested. RESULTS: 93.8% of patients presented with dermatitis affecting mostly the hands (45.1%), feet (21.4%), face (12.6%), and legs (4.6%). Two hundred and twenty-four patients (60%) (male : female = 1 : 2) tested positive for at least one substance. Nickel was the commonest sensitizer (15%) in both genders. "Fragrance mix" (8%), p-tertiary butylphenolformaldehyde (p-TBPF) resin (7.5%), thiomersal (7.5%), chromium (7.2%), cobalt (6.4%), ethylenediamine (6.4%), neomycin (5.1%), and parabens (5.1%) were prominent allergens. Glutardialdehyde, an additional substance tested together with the European Standard Series, scored significantly (4.8%). Variations from the results reported from other countries may be explained by the specific lifestyles and customs of the UAE population. CONCLUSIONS: Substances contained in the TRUE TEST, plus glutardialdehyde, may be considered as the standard series for patch testing in the UAE population.

Cigarette smoking habits among high school boys in a developing country.

The aim of this cross-sectional study was to determine the habits, practices, attitudes and knowledge about cigarette smoking among high school boys aged 15-19 years in the United Arab Emirates, and to provide a basis for comparisons with international data. The World Health Organisation questionnaire was used, together with a multi-stage stratified cluster sampling technique; 1,700 subjects aged 15 years and above were randomly selected. A total of 1,486 individuals (87.4%) from among the populations of Al-Ain City, Abu-Dhabi and Dubai Emirates participated in the study. The prevalence of smoking among the studied group was 19%; 28.2% admitted that they had smoked before but had now given up, and the remaining 52.9% denied having ever smoked. Among 18-year-olds (or older) 30.3% smoked. In 70.8% of cases a friend was reported as having been the first source of their cigarette. Fifty-four percent of smokers started between the age of 10 and 15 years. The families of 15.7% of those studied approved of their smoking, while 78.3% did not: 6% did not have an opinion. Nearly two-thirds of the smokers (66.5%) wanted to stop smoking, while the remaining third (33.5%) did not. Differences in parental education (specifically that of the father) were found to have a significant effect on attitudes towards smoking. Contrary to expectations, the highest prevalence of smoking was found among sons of university graduates, and the lowest among sons of illiterate fathers (12.6% and 24.3%, respectively). There was a statistically significant difference in respect to family income and smoking. Among the ex-smokers, religion (40%) and health (26%) were important reasons for giving up smoking. Of the smokers, 33% claimed that stress is the most important factor which makes people smoke. The source of the student's information regarding smoking hazards was lowest from doctors (17-19%), and highest from the media (35%). All student groups were equally aware that smoking is a risk factor for lung cancer, respiratory diseases, and ischaemic heart diseases, but among the smokers only 28.9% were very concerned about the harmful effects of cigarettes. At the time of their graduation (18 years or older), one-third of the students were already regular smokers, a figure liable to increase as they start university or work.

Renin gene MboI dimorphism is a discriminator for hypertension in hyperlipidaemic subjects.

As renin is the key enzyme of the renin-angiotensin-aldosterone system, the renin gene (REN) represents a good candidate quantitative trait locus for investigations aimed at uncovering the molecular and genetic influences implicated in the molecular etiology of essential hypertension. Among the various polymorphic markers that are available at the REN gene locus, an MboI dimorphic site located in the ninth intron of the REN gene has previously been shown to be significantly associated with a family history of hypertension in a Japanese population and with direct clinical diagnosis of essential hypertension in a Gulf population. We determined MboI allele and genotype distributions in a sample population of 349 (178 men, 171 women) hyperlipidaemic US Caucasians (mean age 55.4+/-13.1 yr), comprising 122 hypertensive and 227 normotensive subjects. A statistically significant association was found between alleles on which the MboI site was present [MboI(+)] and clinical diagnosis of hypertension. REN MboI(+) alleles are thus in linkage disequilibrium with genetic influences that contribute to increased individual susceptibility to hypertension of hyperlipidaemic patients (with an associated odds ratio of 2.15, 95% CI: 1.34-3.45). This positive association does not seem to occur through the effect of classical risks factors represented by lipid, lipoprotein and apolipoprotein levels.

Respiratory symptoms, skin disorders and serum IgE levels in farm workers.

The aim of this study is to evaluate the prevalence of dermo-respiratory symptoms from lung-function spirometer values and serum IgE levels in farmers who have been exposed to pesticides in the United Arab Emirates (E.A.U.). The study was a comparison of 98 farmers with 98 non-farmers, the two groups were equivalent in age, sex and selected regions--the town of Al-Ain and in the Emirates of Dubai, Sharjah and Fujairah. Most of the farmers were illiterate or poorly educated (p < 0.0001). Most lived in prefabricated houses (50.5%). Use of chemical substances (70.9%) and a mixture of pesticides by the farmers (60.2%) was very high. The results revealed that the farmers had a very high prevalence of chronic dermo-respiratory symptoms. These differences are statistically significant when compared with the reference group, particularly for the following symptoms: cough (p < 0.003), pharyngitis (p < 0.0003), bronchitis (p < 0.02), asthma (p < 0.008), respiratory insufficiency (p < 0.006), pneumonia (p < 0.003), dyspnea (p < 0.006), nasal catarrh (p < 0.001), sinusitis (p < 0.05), pharyngeal irritation (p < 0.01), nasal irritation (dryness, sneezing and secretions) (p < 0.005), ocular irritation (p < 0.05), cutaneous pruritus (p < 0.002), and contact dermatitis (p < 0.02). The spirometer tests (all parameters together) measured in the farmers were significantly reduced by comparison with the reference group. In conclusion, the authors suggest that a high prevalence of dermo-respiratory symptoms, supported by reduced spirometer tests and high serum IgE, is associated with exposure to pesticides. These results are clearly useful for establishment of work-related reduced exposure in the future.

A clinical study of airborne allergens in the United Arab Emirates.

BACKGROUND: In the past 25 years the United Arab Emirates (UAE) have experienced a socioeconomic boom. The once nomadic Bedouin population of Al Ain, in the emirate of Abu Dhabi, now lives in modern air-conditioned accommodation, and huge desalination plants have allowed afforestation and farming. OBJECTIVE: To evidence responsible airborne allergens in an UAE population. PATIENTS AND METHODS: 263 UAE Nationals who attended Tawam Hospital (Al Ain, UAE) with a respiratory disease suspected of being of allergic origin, were submitted to SPT and RAST. The choice of pollinic allergens was made in accordance with the local flora and market availability. All patients were SPTed with at least the same battery of 15 pollinic and indoor allergens. Most patients were submitted to at least 4 RAST, viz Cynodon dactylon, Salsola kali, Prosopis juliflora and Dermatophagoides pteronyssinus. RESULTS: 71.8% patients were positive for at least one allergen. Pollen accounted for 61.6% of positive patients, with 45.2% positive to chenopodiaceae, 33% to gramineae and 23.5% to P. juliflora. Indoor allergens were positive in 30.4% of patients with 17.9% positive to D. pteronyssinus and D. farinae, 11% to Blatella germanica, 8.3% to Cat fur, 4.9% to Goat hair, 0.7% to Rat hair and Mouse hair and 1.5% to Candida albicans. CONCLUSION: Pollen was the prominent allergen. There is room, however, for further epidemiological studies possibly with new extracts and RAST specifically designed after the species of the Gulf region.

Safer roads for children in the United Arab Emirates.

A study was conducted to obtain a representative view of the parents of primary school children regarding which strategies should be employed to reduce the toll of road traffic accidents in the United Arab Emirates. A cross-sectional population-based study was conducted in Al-Ain, UAE, in which parents were asked to give their suggestions on how to make the roads safer for their children. Strategies aimed at reducing vehicle speed, improved personal driving, adherence to existing rules, and driver and pedestrian education were regarded as paramount. There is widespread awareness of road safety problems in the country and the public appears ready to accept major safety initiatives by government agencies.

The age and symptomatology of natural menopause among United Arab Emirates women.

OBJECTIVES: To determine the median age of natural menopause in United Arab Emirates women, the factors affecting that age and the prevalence of climacteric symptoms amongst those women. METHODS: A population-based survey was conducted on a community sample of United Arab Emirates women who had had natural menopause defined as cessation of menstruation for at least 6 months at the end of reproductive years. A total of 742 women aged 40 years and above were recruited from both urban and rural areas of the country using the multi-stage stratified cluster sampling technique. Data were collected using a structured questionnaire and face to face interviews and included a number of familial, reproductive and life-style variables. RESULTS: The median age of the menopause in the United Arab Emirates is 48 years (mean = 47.3 +/- 3.29, range 40-59). This is significantly lower than the median age reported from the West (50.3 years). The subject median age of the menopause was significantly related to that of the mother (P < 0.001), older sister (P < 0.001), parity (P < 0.0001) and the previous use of oral contraceptive pills for more than 1 year (P < 0.001). Hot flushes were the commonest feature of the menopause occurring in 45% of women. CONCLUSION: The age of natural menopause in United Arab Emirates women, as in other developing countries, is less than in Western women and may be influenced by genetic factors, parity and previous use of oral contraceptives. Climacteric symptomatology, however, is similar in the different patient groups.

Consanguinity and the age of menopause in the United Arab Emirates.

OBJECTIVE: The study examined the association between some biosocial factors, consanguinity and age at natural menopause in the United Arab Emirates (UAE). METHOD: A cross-sectional population-based study using a multi-stage sampling design and face-to-face interview. RESULTS: In a sample of 800 UAE females aged 40 years and above, there were 742 (85.8%) respondents. The median age of natural menopause was 48 years. The bodyweight, parity number, occupation, smoking habits and consanguinity in marriage were the significant variables associated with the age at natural menopause. There were statistically significant differences between women in consanguineous and non-consanguineous marriages with regard to BMI (P < 0.002), occupation (P < 0.008), weight (P < 0.0001), age (P < 0.03), age of menopause (P < 0.005), parity (P < 0.0001), mother's age at menopause (P < 0.007) and sister's age at menopause (P < 0.002). CONCLUSION: The study showed that among UAE women, consanguinity of marriage, maternal and sister's age at menopause, BMI, parity number and smoking habits significantly influence the natural age of menopause.

Public awareness and attitudes towards epilepsy in the United Arab Emirates.

The aim of this paper is to obtain an initial estimate of people awareness, attitudes and understanding towards epilepsy and to provide a basis for international comparisons. A cross-sectional study conducted during 1995 in Al-Ain City, Dubai and Sharjah Emirates, United Arab Emirates (UAE). We used a simple questionnaire following a two-stage sampling technique. A total of 1050 subjects aged 15 years and above were selected randomly. Of these a total of 892 individuals (86.4%) responded to the study. Seventy-five percent of respondents (665 people) had heard or read about epilepsy. Males and females were similarly familiar with the concept of epilepsy. The age group and education had a positive significant effect on awareness of epilepsy (p < 0.001). Thirty-four percent had occasionally seen a seizure. Nineteen suggested that there is not treatment. Those acquainted with a person with epilepsy were more likely to know that there is treatment. Among those familiar with epilepsy 18.5% believed in cautery and 40% believed in faith healing. A small percentage (7%) of respondents had objections to allowing their children associating with a person with epilepsy at school or in the playground; 68% objected to their children marrying an epileptic person; 10% believed that epileptic people should not be employed in jobs as other people are. In conclusion, unfortunately, knowledge, awareness and attitudes towards epilepsy in the UAE were less compared with surveys conducted in Western countries. The majority lacked information about the causes, nature and treatment of the disease.
