Abstract
The aim of the present investigation was to determine the prevalence of metabolic syndrome.
Materials and Methods: Metabolic syndrome was defined by the presence of three or more of the following components: abdominal obesity, hypertriglyceridemia, low HDL-C, high blood pressure, and high fasting glucose.
Results: In this study, 10368 of the adults (4397 men and 5971 women) aged 20 years and over, participated in Tehran Lipid and Glucose study. The unadjusted prevalence of metabolic syndrome in the study population was 30.1% (CI 95%: 29.2-31.0), and age-standardized prevalence was 33.7% (CI 95%: 32.8-34.6). The prevalence increased with age in both sexes. Metabolic syndrome was more commonly seen in women than men (42% vs. 24%, p< 0.001). Low HDL-C was the most common metabolic abnormality in both sexes. Except for high FPG, all abnormalities were more common in women than in men (p< 0.001). Most of those with metabolic syndrome had 3 components of the syndrome (58%), 33% had four, and 9% had five
components.
Conclusion: This first report on metabolic syndrome from Iran shows a high
prevalence of this disorder, imposing serious impacts on health care system. Efforts
on promoting healthy diets, physical activity, and blood pressure control must be
undertaken.

Abstract
Background: Hyperglycemia is a metabolic response to surgical stress. In this study, patients’ blood glucose changes were measured before, during and after elective eye surgeries under general anesthesia, with two methods: glucometer and glucose oxidase enzyme lab assay. Probable influencing factors and the correlation rate of these two methods were evaluated.
Methods: This analytic cross – sectional original study was performed on 230 American Society of Anesthesiologists (ASA) Class 1or 2 non–diabetic patients. All the patients underwent a similar general anesthesia and their blood glucose levels were measured simultaneously with two cited methods on three occasions.
Results: In all cases, post-surgery blood glucose in comparison to pre-surgery levels increased significantly in both methods irrespective of independent variables of the study. Considering these independent variables, increase in blood glucose levels was significant in most of the patients. The mean increase in blood glucose post-surgery in comparison to pre–surgery, measured with lab assay, had significant statistical correlation with the type of eye surgery but not with other variables like age, gender and duration of surgery. Correlation of the two methods were also partially significant statistically.
Conclusion: Considering the results of this study and the fact that blood glucose changes under general anesthesia is usually unrecognized clinically, we recommend blood glucose measurement in non–diabetic patients during long surgeries. It is advantageous to use Accu–chek (Sensor model) glucometer for this purpose.

Abstract
Background: Hepatitis C is a major cause of chronic liver disease and hepatocellular carcinoma. Hepatitis C infection also has extrahepatic manifestations, including cryoglobulinemia and lichen planus. Lichen planus is a relatively common mucocutaneous disorder, and, due to its chronic pattern and increased incidence of malignancy, diagnosis and treatment of this disease are very important. The aim of the present study was to investigate the prevalence of oral lichen planus in HCV-infected patients.
Methods: In this cross sectional- descriptive study, the prevalence of oral lichen planus was evaluated by means of observation, clinical examination, questionnaire and evaluation of the medical records of 150 patients referred to the hepatitis clinic, gastrointentrology and infectious disease wards of Imam Khomeini Hospital and the Iran Blood Transfusion Organization, Tehran, Iran. We used a sequential method for sampling. Data were analyzed using statistical software (SPSS ver. 11) and the chi-square test.
Results: From a total 150 patients, 133 were male and 17 female. Six cases (4%) had oral lichen planus. All patients with oral lichen planus were male and the buccal mucosa was the most common site.
Conclusions: According to this study, the prevalence of oral lichen planus in patients afflicted with HCV is higher than in the normal population. We should pay more attention to oral lichen planus as one of the extrahepatic manifestations of hepatitis C.

Abstract
Background: Treatment of cervical carcinoma is routinely performed with Low Dose Rate (LDR) brachytherapy, but Brachytherapy in our department is done with Medium Dose Rate (MDR) due to the technical characteristics of the machine available here. Thus we decided to evaluate the results of this treatment in our department in a prospective study.
Methods: Between March 2006 and July 2008, 140 patients with histologic diagnosis of cervical carcinoma referred to Tehran Cancer Institute were treated with external beam radiotherapy (44-64 Gy to whole pelvis) and MDR brachytherapy (8-30 Gy to Point A) with a dose rate of 2.2±0.3 Gy/h.
Results: 121 patients were followed up for a median time of 18 months (range: 9-39 m). There were 11%(6/54) local recurrence for surgery and adjuvant radiotherapy group 25%(16/65) for radical radiotherapy group, and 19%(23/121) for all patients. Rectal and bladder complications incidence for all patients were 10%(12/121) and 13%(16/121) respectively. High grade complication was shown only in one patient in radical radiotherapy group. In this study 3-years disease free survival and overall survival were 73% and 92% respectively, and disease stage (p=0.007) and overall treatment time (p=0.05) were the significant factors affecting disease free survival.
Conclusions: Results of this series suggest that the use of external beam radiotherapy and MDR brachytherapy with about 20% dose reduction in comparison with LDR can be an acceptable technique with regard to local control and complications.

Abstract
Background: Drugs applied topically to the eye may be absorbed systemically to a substantial degree, with the potential to cause serious systemic side-effects. Children may be particularly vulnerable to systemic effects of topically applied agents as topical doses are often not weight-adjusted.
Case presentation: This article describes a case of serious systemic side-effect by the use of topical phenylephrine, tetracaine, tropicamide and atropine in a 17-year old boy candidate for deep viterectomy in Farabi Hospital in 1389. Following application of the aforesaid eye drops, the patient developed hypertension and subsequent loss of conciseness.
Conclusion: Several types of eye drops and their repeated use can lead to their systemic absorption and medical complications due to overdose. Strategies to minimize systemic absorption should be applied, including use of low concentrations of ophthalmic drugs, administration of one type of the drug, use of microdrops and punctal occlusion to minimize absorption via the nasolacrimal duct. While administering ophthalmic drops, one should take these precautions to minimize the systemic effects of the drugs to prevent subsequent complications.

Abstract
Background: Laparoscopic cholecystectomy is a way of removing the gallbladder. But like other surgeries, this procedure has some side effects such as postoperative shoulder pain. This study evaluates the effect of different gas flow rates into the abdominal cavity on postoperative shoulder pain in laparoscopic cholecystectomy patients.
Methods: The study as a randomized clinical trial was conducted on laparoscopic chol-ecystectomy patients in Imam Khomeini Hospital- Esfarayen 2011-2012. One hun-dred participants were selected by available sampling, and were divided randomly into two groups of 50 patients. In group I flow rate of CO2 gas was two liters per minute and in group II flow rate of CO2 gas was five liters per minute. After reversing anesthe-sia, six, 12 and 24 hours post operative, shoulder pain was evaluated by Visual Ana-logue Scale (VAS) pain questionnaire. The study findings analyzed by independent t-test.
Results: The mean age of participants was 48.8±7.5 years and mean surgery duration was 36.5±13.1 minutes, and there was no significant differences between two groups (P>0/05). However, the mean shoulder pain scores in group I (blowing with low pres-sure) was differed significantly with group II (blowing with high pressure) (P<0.05). In group I, pain was lower than group II.
Conclusion: Results showed if CO2 gas flow rate is two liters per minute (blowing with low pressure), the patients complain less shoulder pain. Therefore low pressure gas in-sufflation for laparoscopic surgery is recommended. Further studies in this field should be considered.

Abstract
Background: Postoperative pain is one of the most common complications following laparoscopic cholecystectomy. Because the majority of the analgesic drugs including opioids and nonsteroidal anti-inflammatory drugs have many side effects, using drugs with lesser side effects is beneficial. The aim of this study was to evaluate the effect of N-acetylcysteine on the pain after laparoscopic cholecystectomy.
Methods: In a randomized clinical trial, in two university-affiliated teaching hospitals in Babol City (Shahid Beheshti and Shahid Yahyanezhad Hospitals), Iran, from August 2015 to March 2015, a total number of 38 patients with age of 20-50 years, who were candidates for laparoscopic cholecystectomy with American Society of Anesthesiologists Class-I were chosen and randomly assigned into two groups. The night before operation, 1200 mg oral N-acetylcysteine is given to intervention group. Also, they received 600 mg IV N-acetylcysteine in the morning before operation. In the control group, two vitamin C effervescent tablets as placebo were given at night before operation and 3 ml sterile water as placebo was injected in the morning of operation. Amount of pethidine consumption and the changes in hemodynamic in two groups was recorded and analyzed at 24 hours after operation.
|
Results: The average of patients age was not significant different between two groups (P=0.23). Average of pain score in placebo group was 3.5 and in N-acetylcysteine group was 2.7 that it was not significant difference between two groups (P=0.06). Average of pethidine consumption in placebo group was 52 mg and in N-acetylcysteine group was 29 mg in 24 hours, that the difference was statistically significant between two groups (P=0.01)
Conclusion: As the results of the study, it can be concluded that the anti-inflammatory effects N- acetylcysteine can inhibit the function of lipoproteins and prostaglandins, reduced glutathione peroxidase and dismutase has been restored and can be used to treat pain or analgesic dose reduction. In this study the N-acetylcysteine has reduced pain after laparoscopy and analgesic dose of mepridine.

Abstract
Background: Metabolic syndrome (MetS) is characterized by a combination of cardio-metabolic risk factors. Given that genetic factors have been shown to contribute to individual susceptibility to MetS, the identification of genetic markers for disease risk is essential. Recent studies revealed that rs780094 and rs1260326 of glucokinase regulatory gene (GCKR) are associated with serum triglycerides, plasma glucose levels and metabolic syndrome. The aim of this study was to investigate associations of GCKR gene variants with metabolic syndrome and its components.
Methods: This case-control study was conducted from April to August 2017. In this study, 8710 adults (3522 males and 5188 females), over 19 years, were randomly selected from the Tehran Lipid and Glucose Study (TLGS) population. Based on joint interim statement (JIS) criteria, the subjects were divided into two groups: case and control. Genotyping was performed by HumanOmniExpress-24 v1.0 BeadChips (Illumina, San Diego, CA, USA).
Results: Allele frequencies were in conformity with Hardy-Weinberg equilibrium. Comparisons of allele frequencies by the Chi-square test revealed that frequencies of TT genotype of both polymorphisms were significantly higher among patient group than healthy group. Logistic regression analysis with adjustment for age, gender and CRP revealed that the GCKR polymorphisms (rs1260326: odds ratio 2.7, 95% CI 1.6-4.6, rs780094: odds ratio 2.5, 95% CI 1.5-4.2) were significantly associated with MetS. Frequency of TT genotype was more in persons who had C-reactive protein (CRP) levels above 3 mg/l. The minor T allele of both polymorphisms was significantly associated with increases in the blood serum concentration triglyceride and to a decrease in fasting plasma glucose levels.
Conclusion: The results of our study indicated that, rs780094 and rs1260326 common polymorphisms of the GCKR gene were associated with serum triglycerides levels, fasting plasma glucose levels, and metabolic syndrome in a sample of the Tehranian population (TLGS), as it was already confirmed the inverse effect of this polymorphisms on triglycerides and glucose levels in previous studies.

Abstract
Background: Diabetes Mellitus is a prevalent disease worldwide and foot ulcer is one of the serious complications of chronic uncontrolled diabetes which could lead to various complications such as amputation of the extremity if left untreated. Total contact casting (TCC) is the gold standard in treatment of neuropathic and neuro ischemic diabetic foot ulcers (DFU) on which less emphasize is seen on routine medical practice. The aim of this study was to emphasize on healing effect of this off-loading method and to study the possible influence of variants on the healing rate of this technique.
Methods: In this cohort study, 92 diabetic patients with complaint of plantar foot ulcer grade 0, 1 and 2 according to Wagner classification had participated in Shahid Beheshti Hospital, Babol City, Iran, from March 2014 to February 2016. The demographic and biochemical information along with dimensions of foot ulcers were carefully recorded. After the primary cleansing, surgical debridement and dressing, TCC was applied on foot by the specialist and they were requested to return weekly for changing the TCC and re-evaluation of ulcers. The healing rate was calculated as decline in ulcer surface area per week.
Results: 92 patients of study sample with mean age of 63.9±10.56 year consisted of 76 patients with DM type 2 with BMI of 31.16±3.8 kg/m² and 58 male patients. The average healing rate of ulcers treated with TCC was 0.406 ±0.168 cm²/week. The duration of diabetes on average was 17.23±6.93 years. Most of the patients (n=45) had an ulcer on the forefoot and the healing rate of midfoot ulcers was slower. The average amount of baseline HbA1c was 8.2±0.19%. There was no relation between smoking history (P=0.94) and anti-diabetic regimen used by patients (P=0.754) with the healing rate.
Conclusion: The healing rate is slower in elderly patients and those with longer duration of diabetes. So in these two groups, TCC is to be applied for a longer duration in order to achieve complete healing.

Abstract
Background: The image quality is paramount in interpreting the hepatic dynamic CT scan. A poor quality image results in repeating the procedure, which is very time-consuming for the patient and staff, and besides, it is not cost-efficient. This study intended to determine the correlation between image quality and the Hounsfield unit (HU) of the liver and its vessels in the arterial and venous phase to define the acceptable range of HUs for hepatic CT images.
Methods: The image quality of 146 dynamic CT scans was assessed by qualitative and quantitative methods at Namazi Hospital of Shiraz University of Medical Sciences from September 2019 to August 2021. Two radiologists performed the qualitative evaluation. They categorized the image qualities into three groups; poor, acceptable, and high quality. For quantitative assessment of image quality, the Hounsfield unit of the aorta, hepatic vein, main portal vein, right anterior, right posterior, and left lateral lobe of the liver were evaluated in both arterial and venous phases.
|
Results: According to the results of the qualitative evaluation of image quality, 59.6%, 17.8%, and 22.6% of triphasic CT scans had good, acceptable, and poor quality, respectively. There was a significant relationship between image quality and Hounsfield units of all ROIs in the arterial phase (P<0.005). Also, a significant relationship was observed between the Hounsfield units of the portal vein right on the anterior and posterior segments of the liver (P<0.03) in the venous phase.
Conclusion: In a high quality triphasic CT scan, the Hounsfield unit of different parts in the arterial phase should be as follows: aorta 310±78, portal vein 150±40, hepatic vein 44±7, right posterior and anterior and left lateral segments of liver 77±11, 77±7 and 78±12. Hounsfield units of the portal vein, hepatic vein, and right posterior and anterior segments of the liver in the venous phase should be 155±27, 167±30, 111±19, and 112±16, respectively.
