Rider sitting position widens lumbar intervertebral distance: a prospective observational study

Abstract Background: Reduced lumbar lordosis may make the process of identifying the intervertebral distance easier. The primary aim of this study was to measure the L3-L4 intervertebral space in the same patients undergoing spinal anesthesia in three different sitting positions, including the classic sitting position (CSP), hamstring stretch position (HSP) and rider sitting position (RSP). The secondary aim was to compare ultrasonographic measurements of the depth of the ligamentum flavum and intrathecal space in these three defined positions. Methods: This study is a single-blinded, prospective, randomized study. Ninety patients were included in final analysis. the patients were positioned on the operating table in three different positions to perform ultrasonographic measurements of the spinal canal. The intervertebral distance (IVD), the distance between the skin and the ligamentum flavum (DBSLF) and the intrathecal space (IS) were measured in the L3 -L4 intervertebral space in three different positions. Results: The RSP produced the largest mean distance between the spinous processes. The RSP yielded a significantly larger IVD than did the CSP (p < 0.001) and HSP (p < 0.001). The DBSP was larger in the CSP than in the HSP (p = 0.001). The DBSLF was significantly larger in the RSP than in the HSP (p = 0.009). Conclusions: Positioning the patient in the RSP significantly increased the intervertebral distance between L3 -L4 vertebrae compared to the CSP and HSP, suggesting easier performance of lumbar neuraxial block.

Video-based digital platforms as an educational resource for the surgical preparation of orthopedic surgeons

SUMMARY OBJECTIVE: The aim of the study was to research the video-based digital platforms that orthopedic specialists in Turkey use as an educational resource in their surgical preparations that they have not seen or done before, the frequency of their use of these platforms, and their trust in these platforms, with a survey study. METHODS: The importance of video-based digital platforms in surgical preparations that surgeons have not seen or done before was measured using the data obtained from 181 orthopedic specialists using a survey prepared on an Internet-based server (docs.google.com). RESULTS: Orthopedists used video-based digital platforms with a ratio of 38.7% among the educational resources in their surgical preparations that they have not seen or done before. There was no significant difference between the specialists with a surgical experience of 1-10 years and more than 10 years of experience in terms of using video-based digital platforms in surgical preparation (p>0.05). A total of 81.2% of the participants used only video-based digital platforms in the preparation of a surgical procedure they have never seen before. The most frequently used digital platform was YouTube, and 62% of the participants considered these platforms reliable. CONCLUSION: Orthopedic specialists in Turkey primarily and frequently use video-based digital platforms as a training resource in their preparations for surgery that they have not seen or done before. The establishment or support of platforms with evidence-based content with references from official orthopedic institutions and organizations can increase the trust of orthopedic specialists in these platforms.

Lymphangiectatic Variant of Low-Grade Malignant Eccrine Spiradenoma

Low-grade malignant eccrine spiradenoma (spiradenocarcinoma) is a rare sweat gland tumor, which usually arises from a pre- existing benign eccrine spiradenoma. This paper presents the case of a 55-year-old male who had a lesion in his right elbow for 10 years. The microscopic examination revealed a well-demarcated, multilobulated tumor in the dermis and subcutis, which presented with many blood-filled vessels and extensive hemorrhage.The tumor was composed of hyperchromatic, round to oval cells with nucleolar prominence, mild to moderate atypia, and increased mitotic index. Additionally, lymphangiectatic appearance was observed in areas with prominent stromal lymphedema. P53 and Ki-67 had high positivity. Surgical excision of the lesion was performed with adequate surgical margins, and the dissected lymph nodes in the axilla were tumor-negative. After 15 months of follow-up, there was no recurrence or distant metastasis.

The effect of proliferative hypertrophic scars on determining treatment options for preventing recurrence of vesicourethral anastomotic stenosis after radical prostatectomy: a single-center cross-sectional study

ABSTRACT BACKGROUND: Vesicourethral anastomotic stenosis (VUAS) following retropubic radical prostatectomy (RRP) significantly worsens quality of life. OBJECTIVES: To investigate the relationship between proliferative hypertrophic scar formation and VUAS, and predict more appropriate surgical intervention for preventing recurrent VUAS. DESIGN AND SETTING: Retrospective cross-sectional single-center study on data covering January 2009 to December 2019. METHODS: Among 573 male patients who underwent RRP due to prostate cancer, 80 with VUAS were included. They were divided into two groups according to VUAS treatment method: dilatation using Amplatz renal dilators (39 patients); or endoscopic bladder neck incision/resection (41 patients). The Vancouver scar scale (VSS) was used to evaluate the characteristics of scars that occurred for any reason before development of VUAS. RESULTS: Over a median follow-up of 72 months (range 12-105) after RRP, 17 patients (21.3%) had recurrence of VUAS. Although the treatment success rates were similar (79.5% versus 78.0%; P = 0.875), receiver operating characteristic (ROC) curve analysis indicated that dilatation using Amplatz dilators rather than endoscopic bladder neck incision/resection in patients with VSS scores 4, 5 and 6 may significantly reduce VUAS recurrence. A strong positive relationship was observed between VSS and total number of VUAS occurrences (r: 0.689; P < 0.001). VSS score (odds ratio, OR: 5.380; P < 0.001) and time until occurrence of VUAS (OR: 1.628; P = 0.008) were the most significant predictors for VUAS recurrence. CONCLUSIONS: VSS score can be used as a prediction tool for choosing more appropriate surgical intervention, for preventing recurrent VUAS.

Significance of Preoperative Prone Position Computed Tomography in Free Hand Subaxial Cervical Pedicular Screwing

: The subaxial cervical pedicle screwing technique shows powerful biomechanical properties for posterior cervical fusion. When applying a pedicle screw using the freehand technique, it is essential to analyse cervical computed tomography and plan the surgery accordingly. Normal cervical computed tomography is usually performed in the supine position, whereas during surgery, the patient lies in a prone position. This fact leads us to suppose that radiological evaluations may yield misleading results. Our study aimed to investigate whether there is any superiority between preoperative preparation on computed tomography performed in the prone position and that performed in the supine position. Methods : This study included 17 patients (132 pedicle screws) who were recently operated on with cervical vertebral computed tomography in the prone position and 17 patients (136 pedicle screws) who were operated on by conventional cervical vertebral computed tomography as the control group. The patients in both groups were compared in terms of age, gender, pathological diagnosis, screw malposition and complications. A screw malposition evaluation was made according to the Gertzbein-Robbins scale. Results : No statistically significant difference was observed between the two groups regarding age, gender and pathological diagnosis. The screw malposition rate (from 11.1% to 6.9%, p<0.05), mean malposition distance (from 2.18 mm to 1.86 mm, p <0.05), and complications statistically significantly decreased in the prone position computed tomography group. Conclusion : Preoperative surgical planning by performing cervical vertebral computed tomography in the prone position reduces screw malposition and complications. Our surgical success increased with a simple modification that can be applied by all clinicians without creating additional radiation exposure or additional costs.

Evaluation of factors affecting sexual dysfunction in female patients with diabetes mellitus

ABSTRACT Objective Our objective in this study was to evaluate the factors predicting female sexual dysfunction (FSD) in patients with diabetes mellitus (DM). Subjects and methods The study included 149 women with DM. Sexual function was evaluated with the Female Sexual Function Index (FSFI) questionnaire, in which total scores under 26.55 characterized the occurrence of FSD (Group 1 > 26.55, Group 2 < 26.55). We recorded the patients' demographic, metabolic, and hormonal data. Ophthalmologic, neurologic, and renal complications were also evaluated. The antioxidant status of the patients in both groups was determined by measuring the activity of the enzymes paraoxonase-1 (PON-1) and arylesterase (ARE). Results Based on the FSFI scores, 60 patients were allocated to Group 1 (26.6 ± 12.3) and 89 to Group 2 (22.6 ± 9.5). Group 2 compared with Group 1 had significantly (p < 0.05) higher mean concentrations of glycated hemoglobin (HbA1c), glucose, triglycerides, and insulin, along with higher rates of metformin use, smoking, retinopathy, and nephropathy. The mean serum ARE concentrations were significantly lower in Group 2 compared with Group 1 (p = 0.000), but the mean serum PON-1 concentrations were similar between both groups (p = 0.218). On multivariable regression analysis, age, ARE activity, Beck Depression Inventory (BDI) score, and menopause were significant independent predictors of FSD (p < 0.05). Conclusions In this study, we evaluated the predictive factors determining FSD caused by DM. Despite the significant results found in our study, future randomized controlled studies with a long follow-up and a larger number of patients are required to determine how DM affects FSD.

The association between CHA2DS2-VASc score and erectile dysfunction: a cross-sectional study

ABSTRACT Purpose: This study aims to assess the association between CHA2DS2-VASc score and erectile dysfunction in patients who were admitted to cardiology outpatient clinics. Materials and methods: One hundred and two male patients who were admitted to the cardiology outpatient clinic were included to the study. Erectile dysfunction was evaluated in the urology outpatient clinic in the same hospital and scored using Turkish Version of The International Index of Erectile Function. CHA2DS2-VASc score was calculated for every patient using the current associated guidelines. Results: There was a negative correlation between The International Index of Erectile Function score and CHA2DS2-VASc score, age, hypertension, heart failure, diabetes mellitus, stroke respectively. Smoking and dislipidemia were not correlated with The International Index of Erectile Function score (p>0.05). Conclusion: CHA2DS2-VASc score can be used to detect Erectile dysfunction in patients who are admitted to the cardiology outpatient clinics.

Coronary artery dissection in a patient with Buerger's Disease

Abstract Buerger's disease, vasculitis of small and medium-sized blood vessels, is a non-atherosclerotic and progressive occlusive condition which frequently involves the distal part of the limbs. The occlusion of coronary arteries in Buerger's disease is a rare condition; however, coronary artery dissection has not been reported previously. Therefore, this paper presents a 45-year-old man who developed coronary artery dissection associated with Buerger's disease. The patient was treated successfully with coronary artery bypass grafting with the left internal mammary artery to the left anterior descending artery, and saphenous vein graft to the right coronary artery.

Effect of MDR C3435T polymorphism on Varenicline treatment in quit smoking

Despite so many global efforts, smoking still remains to be one of the most common addictions worldwide. Even though most smokers wish to quit smoking, many of them fail. In this respect, genetic variants are thought to be remarkable factors in nicotine dependence and in treatment of smoking cessation. This is a paper investigating a single variant p-glycoprotein (P-gp) polymorphisms and its effect on Varenicline efficacy in the smoking cessation. 158 smokers and 52 non-smoker healthy volunteers were included. We determined the P-gp C3435T gene polymorphisms in all subjects. Face to face interviews with smokers were performed for smoking cessation and Varenicline was given for smoking cessation. Cessation success was evaluated in the 6th month and success rates were compared according to the P-gp genotype distributions. In our study, smoking cessation rate by Varenicline was 57.0%. This rate was 55.0% in females, and 57.2% in males (p=0.85). The P-gp C3435T gene distribution was similar in control, quitters and not-quitter groups. Cessation rate was at highest point in genotype CT (62.2%) and at the lowest in TT (47.6%). It was 53.8% in genotype CC and there was no statistically significant difference (p=0.27). Our results suggest that genetic variants of P-gp C3435T did not significantly affect Varenicline treatment for smoking cessation.

Syrian civil war: the experience of the surgical intensive care units

Objective: Since the civilian war in Syria began, thousands of seriously injured trauma patients from Syria were brought to Turkey for emergency operations and/or postoperative intensive care. The aim of this study was to present the demographics and clinical features of the wounded patients in Syrian civil war admitted to the surgical intensive care units in a tertiary care centre

Methods: The records of 80 trauma patients admitted to the Anaesthesia, General Surgery and Neurosurgery ICUs between June 1, 2012 and July 15, 2014 were included in the study. The data were reviewed regarding the demographics, time of presentation, place of reference, Acute Physiology and Chronic Health Evaluation II [APACHE II] score and Injury Severity Score [ISS], surgical procedures, complications, length of stay and mortality

Results: A total of 80 wounded patients [70 males and 10 females] with a mean age of 28.7 years were admitted to surgical ICUs. The most frequent cause of injury was gunshot injury. The mean time interval between the occurrence of injury and time of admission was 2.87 days. Mean ISS score on admission was 21, and mean APACHE II score was 15.7. APACHE II scores of non-survivors were significantly increased compared with those of survivors [P=0.001]. No significant differences was found in the age, ISS, time interval before admission, length of stay in ICU, rate of surgery before or after admission

Conclusion: The most important factor affecting mortality in this particular trauma-ICU patient population from Syrian civil war was the physiological condition of patients on admission. Rapid transport and effective initial and on-road resuscitation are critical in decreasing the mortality rate in civil wars and military conflicts

Prevalence of multi-drug resistant uropathogenic Escherichia coli in Potohar region of Pakistan

Objective: To scrutinize patterns of multi-drug-resistant uropathogenic Escherichia coli (UPEC) strains and particularly of fluoroquinolone-resistance this is an alternative choice for the treatment of urinary tract infections. Methods: Bacterial samples (n = 250) were collected from out-patients from August 2012 to August 2014 Islamabad. Antibiotic susceptibility profiling and determination of mini-mum inhibitory concentrations (MICs) and minimum bactericidal concentrations were performed according to the guidelines of Clinical and Laboratory Standards Institute (CLSI, 2012). Genes, qnrA, qnrB and qnrS were identified by DNA amplification and sequencing. Results: The highest percentage of UPEC isolates were resistant to co-trimoxazole (82%) followed by cephalothin (80%), 2nd Gen, 3rd Gen and 4th Gen cephalosporins, respectively. Resistance against gentamicin, amikacin remained 29% and 4%. For other drugs including nitrofurantoin, tetracycline, carbapenem and beta-lactam inhibitors remained below 10%. Altogether, 59% of the isolates were resistant to at least three antibiotics including one fluoroquinolone. Overall, MICs for ciprofloxacin remained (MIC≥256 mg/mL) and for levofloxacin (MIC≥16 mg/mL and 32 mg/mL). No significant differences were observed regarding MIC values of extended spectrum b-lactamase (ESBL) and non-ESBL producers. For qnrS and qnrB positive isolates MICs remained above 32 mg/mL. Prevalence of UPEC was significantly higher among females and 40% of the isolates were ESBL producers. Conclusions: Higher percentages of ESBL producing UPEC were associated with uri-nary tract infections. Moreover, the majority of these isolates were multi-drug resistant and fluoroquinolone-resistant.

The Prevalence of Nocturia and Nocturnal Polyuria: Can New Cutoff Values Be Suggested According to Age and Sex? / 대한배뇨장애요실금학회지

PURPOSE: The aims of this study were to assess the prevalence of nocturia and nocturnal polyuria (NP) and to define new cutoff values according to age and sex for both conditions. METHODS: Data from a population-based prevalence survey conducted among a random sample of 2,128 adults were analyzed in this study. Participants were requested to fill out a questionnaire including the International Continence Society (ICS) definitions of lower urinary tract symptoms and the International Consultation on Incontinence Questionnaire - Short Form. Additionally, a 1-day bladder diary was given to each individual. The participants were divided into 5 age groups. The prevalence of nocturia was calculated based on definitions of nocturia as ≥1 voiding episodes, ≥2 episodes, and ≥3 episodes. NP was evaluated according to the ICS definition. The mean±standard errors and 95th percentile values were calculated in each group as new cutoff values for NP. RESULTS: The prevalence of nocturia was estimated as 28.4%, 17.6%, and 8.9% for ≥1, ≥2, and ≥3 voiding episodes each night, respectively. When nocturia was defined as 2 or more voiding episodes at night, the prevalence decreased significantly. The mean NP index was 29.4%±15.0% in men and 23.1%±11.8% in women. For the age groups of <50 years, 50–59 years, and ≥60 years, the new cutoff values for the diagnosis of NP were calculated as 48%, 69%, and 59% for men and 41%, 50%, and 42% for women, respectively. CONCLUSIONS: We found that the definition of nocturia was still controversial and that waking up once for voiding might be within the normal spectrum of behavior. The definition of NP should be modified, and new cutoff values should be defined using the data presented in our study and in other forthcoming studies.

Effect of GnRH antagonists on clinical pregnancy rates in ovulation induction protocols with gonadotropins and intrauterine insemination

<p><b>INTRODUCTION</b>Intrauterine insemination (IUI) after controlled ovarian hyperstimulation (COH) was applied to selected infertile patients to determine the effect of gonadotropin-releasing hormone (GnRH) antagonists in IUI cycles, in which recombinant follicle-stimulating hormone (rFSH) had been used for COH.</p><p><b>METHODS</b>This study was conducted between April 1, 2009 and June 10, 2009, and involved a total of 108 patients. These patients had primary or secondary infertility, which resulted in an indication for IUI, and they each received two cycles of ovarian stimulation treatment with clomiphene citrate. The patients were randomised into two groups--patients in group A received rFSH + GnRH antagonist (n = 45), while those in group B received only rFSH (n = 63).</p><p><b>RESULTS</b>The mean age of the patients was 31.84 ± 3.73 years and the mean body mass index (BMI) was 24.40 ± 1.88 kg/m(2). The mean age and BMI of the patients in groups A and B were not significantly different. There was no significant difference in the mean total rFSH dose administered (988.33 IU in group A and 871.83 IU in group B). When compared to group B, the mean number of follicles that were > 16 mm on the human chorionic gonadotropin (HCG) trigger day was significantly higher in group A (1.58 and 1.86, respectively; p < 0.05). When the two groups were compared, there were no statistically significant differences in the number of cancelled cycles due to premature luteinisation (none in group A vs. two in group B) and the rate of clinical pregnancy (8.9% in group A vs. 7.9% in group B).</p><p><b>CONCLUSION</b>No significant improvement in the clinical pregnancy rates was observed when GnRH antagonists were used in COH + IUI cycles, despite the significant increase in the number of follicles that were > 16 mm on HCG trigger day.</p>

Evaluation and comparison of the marginal adaptation of two different substructure materials

PURPOSE: In this study, we aimed to evaluate the amount of marginal gap with two different substructure materials using identical margin preparations. MATERIALS AND METHODS: Twenty stainless steel models with a chamfer were prepared with a CNC device. Marginal gap measurements of the galvano copings on these stainless steel models and Co-Cr copings obtained by a laser-sintering method were made with a stereomicroscope device before and after the cementation process and surface properties were evaluated by scanning electron microscopy (SEM). A dependent t-test was used to compare the mean of the two groups for normally distributed data, and two-way variance analysis was used for more than two data sets. Pearson's correlation analysis was also performed to assess relationships between variables. RESULTS: According to the results obtained, the marginal gap in the galvano copings before cementation was measured as, on average, 24.47 +/- 5.82 microm before and 35.11 +/- 6.52 microm after cementation; in the laser-sintered Co-Cr structure, it was, on average, 60.45 +/- 8.87 microm before and 69.33 +/- 9.03 microm after cementation. A highly significant difference (P<.001) was found in marginal gap measurements of galvano copings and a significant difference (P<.05) was found in marginal gap measurements of the laser-sintered Co-Cr copings. According to the SEM examination, surface properties of laser sintered Co-Cr copings showed rougher structure than galvano copings. The galvano copings showed a very smooth surface. CONCLUSION: Marginal gaps values of both groups before and after cementation were within the clinically acceptable level. The smallest marginal gaps occurred with the use of galvano copings.

Physico-chemical analysis and antimicrobial potential of Apis dorsata, Apis mellifera and Ziziphus jujube honey samples from Pakistan

Objective: To evaluate physico-chemical properties and antimicrobial potential of indigenous honey samples against different reference strains including Escherichia coli ATCC 8739, Enterobacter aerogenes ATCC 13048, Pseudomonas aeroginosa ATCC 9027, Bacillus subtilis ATCC 6633, Staphylococcus aureus ATCC 25923, Salmonella typhi ATCC 14028, Klebsiella pneumonia ATCC 13883, Aspergillus niger ATCC 16404, Rhizopus oligosporus PCSIR1, Candida albicans ATCC 14053 and Candida utilis ATCC 9950. Methods: By using standard methods samples were evaluated for their antimicrobial properties including additive effect of starch and non-peroxidase activity, antioxidative properties (phenol contents, flavonoid contents, 1,1-diphenyl-2-picrylhydrazyl radical scavenging activity). Prior to this evaluation, complete physico-chemical properties including pH, color, ash contents, protein contents, moisture contents, hydroxymethyl furfural contents, total sugar contents, reducing sugar and non-reducing sugar contents were analyzed. Results: Relatively higher ash contents were found in the Siddar honey i.e. (0.590 0±0.033 6)%and small honey showed relatively higher protein contents i.e. (777.598±9.880) mg/kg. The moisture contents of tested honey samples ranged between 13.8%-16.6%, total sugar contents from 61.672%-72.420%and non-reducing sugar contents from 1.95%-3.93%. Presences of phenolic contents indicate higher antioxidant potential of these honey samples. All bacteria showed clear inhibition zones in response to tested honey samples whereas fungi and yeast showed inhibition at higher concentrations of these honey samples. For Escherichia coli, Bacillus subtilis, Salmonella typhi, Pseudomonas aeroginosa and Aspergillus niger, overall the small honey showed the higher activity than other honey samples. Conclusion: Physico-chemical analysis of honey samples confirmed good quality of honey according to the standards set by European Union Commission and Codex Alimentarius Commission. Evaluation of these honey samples confirms antimicrobial potential of particular types of honeys indigenous to Pakistan.

Rubella seroprevalance among the girls [aged 7-15] in the primary-school period living in low and high socio-economic areas in Denizli, Turkey

Immunity against rubella before women's reproductive age is a practical strategy to control congenital rubella syndrome [CRS]. This study was designed to investigate the rubella seroprevalance among the female primary-school students living in low and high socio-economic areas in Denizli [Turkey]. Two hundred seventy seven students were eligible for this comparative cross-sectional study [November 2003]. Schools and classrooms were randomly included in the sample. The cut off points of blood sample were set as <10 IU negative; [3]10 - <15 IU indeterminate; [3]15 IU positive. Study was completed in 235 [84.8%] students. Rubella seropositivity was 74.0% [p=0.03]. Rubella vaccination rate was 14.0% [high SES] and 7.8% [low SES]. A significant difference continued among the graders even after multivariable adjustments [p<0.001]. Sporadic rubella vaccinations may not be a right option to control rubella among women in their reproductive age thus active immunization is important for public health in developing countries

Effects of passive smoking in the work place on expiration air carbon monoxide [CO] and carboxihemoglobin [COHB] levels: results of a survey in Turkey

To assess the prevalence of smoking and the effects of passive smoking among bank employees. This cross-sectional study was conducted between 2001 and 2002. Data was collected through questionnaire. The level of Carbon Monoxide [CO] and the percentage of Carboxihemogtobin [COHb] level in the blood were measured by using Bendfond Pico Smokertyser. Chi-square and ANOVA were used. Six hundred fifty four respondents participated in the study which included 384 [58.7%] male and 267 [40.6%] female. The mean value for CO in the expiration air was 14.57 +/- 11.1 ppm [[18.49 +/- 11.21, 7.74 +/- 5.71 and 4.85 +/- 2.35; for current smokers, non-smokers with current exposure and non-smokers without current exposure, respectively [p<0.001]]. The mean value for COHb% was 2.97 +/- 1.9 [[3.60 +/- 1.88, 1.80 +/- 1.17 and 1.21 +/- 0.99; for current smokers, non-smokers with current exposure and non-smokers without current exposure, respectively [p<0.001]. Passive smoking is still a significant health problem in the work place. Anti-tobacco implementations should be carried out strictly in all work places

Diagnostic accuracy of the American diabetes association criteria in the diagnosis of glucose intolerance among high-risk Omani subjects

Type 2 diabetes mellitus is highly prevalent in the rapidly growing Omani population. The American Diabetes Association [ADA] has recommended new criteria for Type 2 diabetes, but the new criteria have been challenged as inadequate. We measured the sensitivity and specificity of the ADA criteria compared with World Health Organization [WHO] criteria for the diagnosis of abnormal glucose intolerance in Omani subjects. Subjects not known to have diabetes were recruited from the Lipid and Endocrine Clinics at Sultan Qaboos University Hospital between 1999 and 2001. Fasting and 2-hour post-75g oral glucose tolerance test [OGTT] glucose levels were measured according to WHO criteria. 176 subjects were recruited for the study. WHO and the ADA criteria were in agreement for 104 out of 115 normal glucose tolerance [NGT], 4 out of 38 impaired glucose tolerance [IGT], and 14 out of 23 diabetic tolerance glucose [DGT] corresponding to a sensitivity of 90%, 10%, and 61% for NGT, IGT, and DGT, respectively. Compared with WHO criteria, the ADA criteria had 30% sensitivity and 90% specificity overall. Comparing fasting glucose cutoff values for the diagnosis of IGT, a cut-off of 5.9 mmol/L yielded the best diagnostic sensitivity and specificity compared to the 6.1 mmol/L recommended by the ADA criteria as determined by the receiver-operating characteristics [ROC], with an area under the curve of 0.677 vs. 0.387, respectively. The ADA criteria had poor sensitivity in the detection of impaired glucose tolerance in high-risk Omani subjects compared with WHO criteria
