Association of selective HLA class II susceptibility-conferring and protective haplotypes with type 2 diabetes in patients from Bahrain and Lebanon.
(9/43)
The association of HLA class II with type 2 diabetes (T2DM) was investigated in Bahraini and Lebanese subjects. DRB1*070101 (Lebanese and Bahraini) and DQB1*0201 (Lebanese) were susceptibility-conferring alleles, and unique susceptibility-conferring/protective haplotypes were found in both patient groups. Regression analysis confirmed that DRB1*070101-DQB1*0201 (Bahraini) and DRB1*110101-DQB1*0201 (Lebanese) were susceptibility-conferring haplotypes. (+info)
Death anxiety in patients with epilepsy.
(10/43)
PURPOSE: Whereas the relationship between epilepsy and anxiety has received much attention, less is known about the relationship between death anxiety and this disorder. The objective of this study was to assess death anxiety among epileptic patients who attended the outpatient neurology clinic at the Salmaniya Medical Complex, Kingdom of Bahrain. METHODS: Ninety-two patients (48 males and 44 females) completed a death anxiety scale. The scale items were adopted from already published surveys and adjusted to suit epilepsy patients. RESULTS: Results showed that the mean death anxiety score was moderate (2.75+/-1.35), with 26.09% of patients reporting high levels of death anxiety. Period of illness and educational level were significant predictors of death anxiety. Female patients, generalized type of epilepsy, the short duration of the illness and low level of education were associated with higher death anxiety scores. CONCLUSION: This study highlights the need for developing treatment strategies, counseling therapies and social support for people with epilepsy to decrease their death anxiety and improve their quality of life.

Rhinoscleroma: a clinicopathological study from the Gulf region.
(11/43)
INTRODUCTION: Rhinoscleroma is a chronic progressive inflammatory disease of the upper respiratory tract. We report a clinicopathological series from the Gulf region. METHODS: The clinical and pathological features of patients diagnosed with rhinoscleroma at three main hospitals in Saudi Arabia and Bahrain over a 20-year period are presented. Archived glass slides and paraffin blocks from these patients were retrieved from the pathology files for review. Special stains were performed whenever indicated. Biopsy material and clinical data from 25 patients formed the basis of this study. RESULTS: Most of the patients were young females with a median age of 24 years. The nose was involved in all cases with frequent extension to other parts of the upper respiratory tract. The provisional clinical diagnoses included syphilis, midline granuloma and malignancy. The histological differential diagnoses included leprosy, malakoplakia and metastatic renal cell carcinoma. CONCLUSION: Rhinoscleroma is rare in Saudi Arabia and Bahrain. Awareness of possible clinical presentations and early diagnosis will significantly reduce the morbidity caused by this disease. (+info)
The Gulf Survey on Anemia Management (GSAM 2005).
(12/43)
We conducted this study to determine the achievements of the current practice guidelines in the management of anemia in the Arabian Gulf Countries. The survey was designed as a retrospective, one day screening of adult patients with end-stage renal disease in six Arabian Gulf countries including Saudi Arabia, Kuwait, Bahrain, Oman, United Arab Emirates and Qatar. Data were collected on patients undergoing chronic dialysis. For random patient sampling, each participating center drew up an alphabetical list of all hemodialysis (HD) or peritoneal dialysis (PD) patients which were 18 years or older and selected every fourth patient on the list. A total of 563 patients from 18 centers were included in the survey. The most common cause of end-stage renal failure was diabetic nephropathy, closely followed by chronic glomerulonephritis. The majority of patients were treated by HD, with only 20% receiving PD. The mean (+/-SD) hemoglobin (Hgb) concentration was 115 +/- 15 g/L (median, 115 g/L; range, 61-159 g/L). The Hgb concentration was > or = 110 g/L in 28%, > or = 120 g/L in 38% and < 100 g/L in 16%. Information on their iron status was available for 97% of patients, ferritin levels were available for 97% and TSAT values for 67% were available. The mean serum ferritin concentration for the study patients was 503 +/- 406 ng/ml (median, 390 ng/ml; range, 20.0-2960 ng/ml); 90.5% had a serum ferritin concentration > 100 ng/ml. We conclude that the results of our study demonstrate anemia management in the Gulf countries which is comparable to the European Survey on Anemia Management 2003 (ESAM 2003). However, many patients still have not reached the current recommendation of anemia management. (+info)
Invasive capabilities of Campylobacter jejuni strains isolated in Bahrain: molecular and phenotypic characterization.
(13/43)
The association between putative virulence genes in Campylobacter jejuni clinical isolates, in vitro invasive capability and severity of infection is yet to be clearly described. We have characterized three virulence genes and correlated their presence with the severity of infection and in vitro invasiveness. We studied eight C. jejuni strains isolated from patients whose clinical data were scored to determine severity of infection. Cytolethal distending toxin (cdtB), invasion associated marker (iam) and Campylobacter invasion antigen (ciaB) genes were detected by PCR and INT407 cells used for invasion assays. Two strains positive for all three genes were the most invasive and isolated from patients with the most severe infection. Four strains positive for two genes and two strains negative for all the three genes were identified. The two cdtB(+ve)/ciaB(+ve) strains were more invasive than the cdtB(+ve)/iam(+ve) strains. One of the cdtB(-ve)/ciaB(-ve) strains showed invasion levels similar to cdtB(+ve)/ciaB(+ve) strains, but the second strain had a non-invasive phenotype. The findings indicate a correlation between in vitro invasive capability, and the presence of all three genes. The pattern of association between invasiveness and molecular characterization suggests that the ciaB gene confers a more invasive capability. (+info)
Kidney disease in Bahrain: a biopsy based epidemiologic study.
(14/43)
The aim of this study was to establish the incidence of renal diseases in Bahrain based on biopsy proven results during the period from January 2003 to October 2006. We studied a total of 145 biopsies obtained from 130 patients; glomerular diseases constituted 64.8%, renal allograft biopsies 23.4%, chronic glomerulosclerosis 8.9%, and others 4.1% of the total. Primary and secondary glomerular diseases were presented equally. The incidence of renal biopsies 5.4/100,000 per year. Minimal change disease-focal segmental glomerulosclerosis (MCD-FSGS) complex was the commonest of all primary glomerular diseases, and lupus nephritis was the commonest secondary glomerulopathy in the biopsied patients. We conclude that there was no significant change in the pattern of glomerulonephritis in Bahrain in comparison with our previous report. (+info)
Management of acute diarrhoea in primary care in Bahrain: self-reported practices of doctors.
(15/43)
This nationwide study was conducted to assess the extent of adherence of primary-care physicians to the World Health Organization (WHO)-recommended guidelines on the use of oral rehydration therapy (ORT), antimicrobials, and prescribing of other drugs used in treating symptoms of acute diarrhoea in Bahrain. A questionnaire-based, cross-sectional survey was carried out in primary-care health centres. During a six-week survey period (15 August-30 September 2003), 328 (25.2%) completed questionnaires were returned from 17 of 20 health centres. In a sample of 300 patients, oral rehydration salts (ORS) solution was prescribed to 89.3% (n=268) patients; 12.3% received ORS alone, whereas 77% received ORS in combination with symptomatic drugs. Antimicrobials were prescribed to 2% of the patients. In 11.4% of the cases, rehydration fluids and other drugs were given parenterally The mean number of drugs was 2.2+0.87 per prescription. In approximately one-third of the patients, three or more drugs were used. Primary-care physicians almost always adhered to the WHO guidelines with respect to ORT and antimicrobials. However, in several instances, ORT was prescribed along with polypharmacy, including irrational use of drugs for symptomatic relief. Effective health policies are needed to reduce the unnecessary burden on the healthcare system. (+info)
Modulation of type 1 diabetes susceptibility by tumor necrosis factor alpha -308 G/A and lymphotoxin alpha +249 A/G haplotypes and lack of linkage disequilibrium with predisposing DQB1-DRB1 haplotypes in Bahraini patients.
(16/43)
Tumor necrosis factor alpha (TNF-alpha) -308 G/A and lymphotoxin alpha (LTalpha) +249 A/G single-nucleotide polymorphisms were investigated in 228 type 1 diabetes mellitus (T1DM) patients and 240 controls. Only LTalpha +249G allele and +249G/+249G genotype frequencies were higher among patients, and no linkage disequilibrium was found between TNF-alpha/LTalpha alleles and susceptible/protective DRB1-DQB1 haplotypes. TNF-alpha/LTalpha T1DM-susceptible (-308G/+249G) and protective (-308G/+249A) haplotypes were identified. (+info)
