Background: Iranian researchers and
scientists in the fields of psychiatry and psychology undoubtedly need to spend
more time and make considerable efforts to prepare and validate Persian
versions of measurements. The present study was designed to validate HADS in Iranian clinically anxious and depressed patients compared to normal
population.
Methods: 261 anxious and depressed patients referred to the inpatient clinic of Rouzbeh
Psychiatric Hospital, Tehran, and 261 healthy volunteers (matched for their sex) were tested using HADS, and two additional clinical tools, ie., BDI & BAI. Then the patients were interviewed by a psychiatrist or a psychologist
(using DSM IV checklist) and rated for their anxiety and
depression severity levels based on a 10-point scale from 1 to 10. BDI and BAI were regarded as objective device providing other external criteria to
examine validity further. Moreover, to assess reliability 10% of the patients (n= 27) were randomly selected
and re-tested after three days.
Results: Findings showed that all measures and their subscales proved to be valid
and reliable with good internal consistencies in Iranian depressed and anxious
patients. This study provides clinicians and researchers with Iranian cut-off
points for HADS, BDI and BAI, to be used in their settings, to categorize
the patients with different levels of psychopathology.
Conclusion: The results support the use of
all the measures and subscales examined in this study in clinical and research
settings. The cut-off points obtained in this study are somehow different from
those presented by original authors which will be discussed from cultural point
of view in this report.

Background: Asthma prevalence has
increased in developed and developing countries in several last decades. Although
cigarette smoking is an identified risk factor for many diseases such as coronary
Heart disease and chronic obstructive lung disease, its effect on asthma is
controversial. The aim of this study was to determine the odds ratio and its confidence
interval for asthma morbidity among children referred to the Immunology and
Allergy department of children medical center according to their parents'
smoking and daily cigarette consumption.
Methods: A case-control study was conducted during two years period on the asthmatic
patients who referred to Immunology and Allergy department of children medical center.
Demographic information and parents' smoking and daily cigarette consumption
assessed by a questionnaire. Healthy children with same age and sex were entered
to the study as the control group. Statistical analysis was performed to
calculate odds ratio.
Results: Among 215 patients who entered the study 63 patients were exposed the cigarette smoke. Odds ratio for asthma morbidity
among children whose parents smoke more than five cigarettes per day in
comparison with whose smoke less than five or do not smoke was 2.38 (p<0.01).
Conclusion: Parent's cigarette smoking is
a risk factor for childhood asthma and could increase the risk of asthma to 2.38 folds in children whose
parents smoke more than five cigarettes. Increasing in parents' knowledge level
that probably relate to their education results in cigarette consumption
decline.

Abstract
Background: Laryngotracheal stenosis is one of the most challenging problems for otolaryngologists. Several methods were developed to treat this problem. However, in many cases, this symptom could be recurred and the patients would suffer from operations for treatment. In this survey, the effect of topical mitomycin-C after laser therapy and dilatation for preventing laryngotracheal stenosis is considered. Methods: Twenty three cases suffered from laryngotracheal stenosis were studied in a clinical trial between years 2006-2007 in Amir-alam educational Hospital in Tehran, Iran. The patients were divided into two groups. In 12 patients (case group), we used topical mitomycin-C (1mg/ml for 4 min) after dilatation and laser therapy, and in 11 of them (control group), this solution was not used. All patients were controlled by endoscopy one and three months later, and then followed up. The results of this study were compared statistically. Results: In the control group after treatment (dilatation and laser), the average changed- vertical and horizontal lengths of stenosis were 0.47±0.77mm and 0.50±0.60mm respectively. However in the control group these changed averages were 2.28±1.15mm and 2.23±1.03mm, respectively after treatment (p<0.0001). The average changed cross section between the two groups were different significantly (p<0.0001), too. Conclusions: In the laryngotracheal stenosis, the use of topical mitomycin-C could reduce the recurrence of the stenosis after dilatation and after the laser procedures. In addition, the need for repeated therapy will be reduced.

Abstract
Background: Meningiomas are among the most common tumors of the brain. Skull base meningiomas comprise s major part of brain meningiomas. They are difficult to treat because of proximity to major vital neuro-vascular structures which makes their surgical resection hazardous and fraught with a high rate of complications. Radiosurgery is considered as an alternative efficient way to treat them, which targets the tumor and its supplying vasculature. The standard treatment consists of tumor eradication and its supplying vessels through homogeneous dose of 201 rays of cobalt
60 source.
Methods: In a case-series study, we report 230 meningiomas referred to Iraninan Gamma Knife Center, treated by radiosurgery with type C Gamma Knife. Radio-surgery was performed at a mean dose of 15 Gy and 50% isodose.
Results: Two hundred and thirty of all meningioma cases refered to our institute were skull base lesions. Eighty (35%) were new case and the rest were previously treated microsurgically one or more times. None of the patients died after treatment and the most common post-operative complications were headache (30 patients) and peri- tumoral edema (12 patients).
Conclusion: Tumoral control is defined as reduced tumor volume or as no change in tumor volume. Tumor control was achieved in 218 (95%) patients. In those who were not treated microsurgically, clinical improvement was more pronounced. Thus when suitable (favorable tumor size and absence of progressive mass effect signs) the patients could be primarily treated with Gamma knife. Other patients could be managed complementarily with radiosurgery after they are treated surgically.

Abstract
Background: Paranasal sinus disease is one of the most common problems of patients that refer to ENT centers. Adding to clinical examination imaging plays an important role in diagnosis and treatment. Also the imaging of paranasal sinuses is necessary before surgery. Although computed tomography is the modality of choice for these areas, it has some disadvantages which the most important one is its high patient's dose. The aim of this study is the comparison between cone beam volumetric tomography and conventional computed tomography computed tomography, in evaluation of these areas.
Methods: In this descriptive-analytic study Coronal computed tomography imaged and cone beam volumetric tomography images were performed for 40 patients referred to ENT department of Amir Aelam Hospital in Tehran, Iran. Computed tomography images were observed by general radiologist and cone beam volumetric tomography images by Maxillofacial radiologist and their results' were recorded. Also ENT surgeon recorded her observations during surgery. Data were analyzed using McNemar test with Kappa and weighted Kappa agreement coefficient.
Results: No statistical difference was shown between the efficacy of computed tomography and cone beam volumetric tomography in evaluation of paranasal sinuses (p> 0.05).
Conclusion: As there was not any difference between conventional computed tomography and cone beam volumetric tomography in the assessment of paranasal sinuses and additional advantages of the later, cone beam volumetric tomography is suggested for paranasal sinus imaging before surgery.

Abstract
Background: Gall stone is an important health problem in the world for which different risk factors have been characterized. Gall stone and cardiovascular disease have common risk factors. Homocysteine is accepted as one of the risk factors for cardiovascular disease. We aimed to study the effect of homocysteine level on gall stone formation.
Methods: 54 patients with gall stone-related diseases and 54 patients without stone (control group) were studied from January 2007 to December 2008. Control group consisted healthy subjects with ultrasound proven normal gallbladder. Serum homocysteine level was checked in both groups. Homocysteine level of equal or more than 15 mmol/l was considered as abnormally high.
Results: Cases included 43 women (79.6%) and had mean age of 50.76±15.23 years. Homocysteine level was significantly higher in patients with gallstone in comparison to control group (p=0.014). Risk of gall stone increased 3.4 times in persons who have homocysteine level equal or greater than 15mmol/l (p=0.019). The mean level of homocysteine was higher in men than women (p=0.03). The mean level of homocysteine did not differ significantly in patients with simple gallstone and patients with gallstone-related inflammation disorders (cholecystitis, cholangitis, and pancreatitis). Additionally, one unit increase in BMI level was associated with 1.12 times increase in the risk for gall stone formation (p=0.035).
Conclusion: The homocysteine level is increased in patients with gall stone-related diseases. Homocysteine may be considered as a risk factor of gall stone formation.

Abstract
Background: Numerous use of Beta Lactame in treatment of bacterial infections resulted in increments of drug resistance of such bacteria. One of difficulties in treatment of hospital infections is Extended Spectrum Beta Lactamase (ESBL) among isolated clinical strains of E.coli. Since some of ESBL strains shows double reaction in drug sensitivity test at in vitro and in vivo condition, therefore it makes difficulties in selection of right treatment. In the last years, CTX-M enzymes have become the most prevalent ESBLs in worldwide. The prevalence of ESBL types largely remains unknown in many parts of the Iran. This study was made to find the prevalence of ESBL-producing E.coli and molecular detection of CTX-M-1 in Tabriz.
Methods: In the present study, 400 urine samples collected between November 2009 and April 2010, from Tabriz Hospitals were studied. Out of the 400 samples, 188 E.coli isolates were detected by standard biochemical tests. Susceptibility to antimicrobial agents was tested to 10 antibiotics by the disk agar diffusion (DAD) method. ESBL production was screened by phenotypic test that included both separate and combined disk agar diffusion techniques. The screened isolates were investigated by PCR assay to detect CTX-M-1 gene.
Results: From the total 188 E.coli isolates, 82 (43.6%) were shown to produce ESBLs by phenotypic test. During the PCR method on the 82 isolates, 69 (84.1%) were confirmed as CTX-M-1 producing group.
Conclusion: The present study showed that CTX-M-producing isolates were increasing among E.coli strains and indicated the need for adequate susceptibility tests in laboratories for choosing the appropriate antibiotics for treatment.

Abstract
Background: Prevalence of Abdominal Aortic Aneurysm (AAA), estimated by various studies, ranged from 4.1% to 14.2% in men older than 60 years. Most cases of AAA are asymptomatic and often discovered incidentally. Approximately the initial presentation in 12% of cases of AAA is sudden rupture with subsequent high mortality. This study was performed to evaluate the prevalence and screening necessity of AAA among Iranian men older than 65 years old.
Methods: In this cross-sectional study, men older than 65 years, who referred for ultrasound examination to three different centers in Tehran, Iran at the year 2008 were included for evaluation of size of the abdominal aorta and presence of AAA.
Results: A total of 240 men older than 65 years enrolled in this study. AAA was found in 24 of the participants with prevalence rate of 10% in the studied population. Mean diameter of detected aneurysms was 3.931.435 cm. In 4 (1.7%) subjects, aneurysms greater than 5.5 cm in diameter were detected. One of these four subjects had the history of coronary artery disease and one was cigarette smoker. Three out of four had history of hypertension.
Conclusion: Considering the estimated prevalence rate of AAA by the current study and the population of Iranian men older than 65, implementing of mass screening for AAA in this group would detect 986 asymptomatic cases each year. Therefore, the authors recommend further studies about the cost-effectiveness of mass screening for AAA among Iranian men above 65 years.

Background: Breast
cancer is the most common form of hereditary cancer worldwide and is an
important cause of morbidity and mortality. Approximately 5-10% of breast
and ovarian cancers are
due to the highly penetrating germline mutations in cancer predisposing genes. Two genes, BRCA1 and BRCA2, account for
at least half of these cases. The demand for BRCA1 and BRCA2 mutation screening is rapidly
increasing as their identification will affect the medical management of people
at increased risk for the disease. Therefore, the aim of this study was to
investigate BRCA1/2 mutations in 100 high risk Iranian families.
Methods: One hundred families who met the
minimal risk factors for breast/ovarian cancer were screened among
the families referred to Kawsar Human Genetics Research
Center for the diseases in 2009-2011. The entire coding sequences and each
intron/exon boundaries of BRCA1/2 genes were screened for by direct
sequencing and MLPA in both patients and the controls.
Results: In the present study, we could detect
the following novel mutations:
p.Gly1140Ser, p.Ile26Val,
p.Leu1418X, p.Glu23Gln,
p.Leu3X, p.Asn1403His,
p.Asn1403Asp, p.Lys581X,

Abstract
Background: Epidemiological studies have reported positive, negative, U-shaped or J-shaped association between high blood pressure and cognitive function as well as dementia whereas other studies have not reported any significant association. The aim of this study was to examine the association between hypertension and cognitive impairment in the elderly residents of Kahrizak Charity Foundation (KCF).
Methods: This cross sectional study was done in Kahrizak Charity Foundation in suburban areas of Tehran, Iran during 2008. The data were collected over one week. Among the 850 elderly residents of the Foundation who were ≥ 65 years old, 185 individuals were chosen randomly. The Mini-Mental State Examination (MMSE) was completed for all. Mean of all blood pressure readings were recorded while anthropometric and biochemical measurements were performed.
Results: The findings indicated that in participants with cognitive impairment, systolic blood pressure, diastolic and mean blood pressures were higher than people with normal cognitive function but the differences were not significant statistically. The odds ratio of cognitive impairment in patients with and without hypertension was 1.52 and 1.58, respectively (P>0.05).
Conclusion: This study did not show any significant association between hypertension and cognitive impairment in the elderly residents of Kahrizak Charity Foundation.

Abstract
Background: Anosmia is a physical sign in post-traumatic patients, which significantly reduces the quality of life. Anosmia occurs in up to 30% of cases with head trauma. In this study we aimed to compare the Olfactory Bulb Volume (OBV) in patients with posttraumatic anosmia in different impact positions and also with healthy individuals to find the relation between the two variables.
Methods: Thirty-eight patients with posttraumatic anosmia and 27 healthy individuals with normal olfactory function were recruited in this case-control study performed in Amir Alam Hospital in Tehran, Iran. Variables of age, sex, time of trauma, site of trauma (frontoparietal/occipital), side of trauma, OBV, the results of olfactory identification tests and olfactory threshold were extracted and evaluated. We used non-contrasted 1.5-Tesla coronal brain MRI for the measurement of OBV.
Results: There were no significant differences between cases and controls regarding sex and age. Olfactory bulb volume was significantly smaller in cases compared to the controls (P=0.004). Among the case group, OBV was smaller in anterior versus posterior head traumas (P=0.02). OBV was also smaller in ipsilateral rather than the contralateral side of trauma (P=0.01).
Conclusion: The direction of trauma had a significant effect on OBV and it was smaller in traumas to the anterior and also ipsilateral sides of the head. It seems that changes in OBV differ due to the direction of head trauma and it can be helpful in predicting the prognosis of posttraumatic anosmia. Further studies are required for more conclusive statements.

Abstract
Background: Evaluation of diastolic dysfunction and its relationship with TIMI frame count in patients with stable coronary artery disease referred to Ayatollah Taleghani Hospital in Tehran in the years 2010-2011 is the purpose of this study.
Methods: Patients were divided into two groups: case and control. Both groups had chronic angina. Patient information on check list has been studies based on data provided by angiography and echocardiography methods.
Results: Cases had significantly higher values of corrected TIMI frame count (TFC) for the left anterior desending artery (LAD), TFC for Circumflex artery (Cx) & Right coronary artery (RCA), (mean TFC P<0.001). Conventional echocardiography showed significantly lower maximal peak systolic velocity (sm) (cm/s), Correlation of early diastolic velocity at myocardial segments (Em) & peak systolic velocity at myocardial segments (Sm) with mean TFC in all 3 vessels were significant (P=0/0001). Ratio of maximal early to late diastolic filling (E/A), in patient with TFC≥ 21 was 0/7 & in patients with TFC≤21 was 1. DT (Deceleration time) had no significant correlation with TFC. Mean of isovolumetric relaxation time (IVRT) in cases was 91 m/s & in controls was 72 m/s Which was higher in patients with mean TFC ≥21. Correlation between mean of angiography and diastolic disfunction was significant.
Conclusion: According to this study diastolic dysfunction which estimated by echocardiography showed significant correlation with TIMI frame count in chronic stable angina patients. Due to simplicity, low cost, quality and reproducibility of this method, this will be helpful.

Abstract
Background: Percutaneous endoscopic gastrostomy (PEG) is one of the ways to non-oral feeding in patients with dysphagia caused by conditions such as stroke, oropharyngeal malignancy and motor neuron disease. The aim of study was assessment of early outcome of PEG in hospitalized patients according to clinical situation and underlying disease.
Methods: This study was cross- sectional and prospective. Sixty five patients were included with PEG from April 2011 to July 2012, at Sina University Hospital, Tehran, Iran. Tube function, feeding, and patients' symptoms were assessed and patients were followed six month at least to one year after procedure .The follow up of patients were stopped if the patient died or removal of tube.
Results: Sixty five patients (33 men, 32 women) enrolled in this study. The mean age of patients was 57.45±16.83 years (19-94 years). Head trauma and postoperative thoracic surgery were in 15 (23.1%) and 4 (6.2%) cases. 36 of patients (55.39%) had no symptoms. The complications include lickage (11 cases), stenosis (9 cases), cellulitis (7 cases), and PEG separation (2 cases). A total of 29 patients were complicated and 21 patients (72%) of them complicated 2 -5 months after PEG. No statistical significant differences between two sexes in PEG complication. 27 patients (41%) died that have no relation to complications of PEG.
Conclusion: Finally, the study showed the PEG is a safe method to enteral nutrition. The advantages of this method include its simplicity, no need to general anesthesia and low rate of complications especially in inpatient under the supervision of medical staff. Therefore it can be used as a favorable method.

Abstract
Background: Detection of retained foreign bodies remains a significant problem in the emergency department. Foreign bodies can go undetected causing infectious complications ultrasonography is too inaccessible and expensive. The purpose of this study is comparison of ultrasonography with radiography for the detection of cervical esophageal foreign bodies
Methods: This cross-sectional study evaluated 58 patients referred with suspected upper esophageal foreign body in the Emergency Department, Amir Alam. Patients were evaluated with ultrasonography and x-ray. After surgical exploration, different type of foreign bodies were recorded. The SPSS statistical software was used for analysis. For applicable efficacy outcome measures, a Spearman correlation was used. Differences were significant when P<0.05. All values were expressed as the frequency and present.
Results: Fifty eight patients were studied. 25 patients (43.4%) were male and 31 patients (56.9%) were female, in 28 (48.2%) patients foreign bodies were detected in radiography. 30 patients (51.8%) were not recorded in techniqe. It was found in patients 22 (78.6%) organic body, and six cases (21.4%) non-organic body. radiographic outcomes in patients with foreign bodies were positive in 26 patients (92.9%) and in two patients (7.1%) were negative. Ultrasound results were positive in 27 patients (96.4%) and in one patient (3.6%) were negative. Association of ultrasound and radiography results were significant in patients with foreign body (Spearman correlation=0.896, P=0.001 Kappa=0.890).
Conclusion: These reports suggest that result of ultrasound with radiography for the detection foreign bodies in cervical esophagus have good agreement. The use of ultrasonography in the emergency department to detect and eventually remove foreign bodies by emergency physicians is an important issue because there is not always an ultrasound technologist or radiologist available.

Abstract
Background: The role of gram-positive cocci especially Staphylococci species in causing urinary tract infection are well known. Among the Staphylococci species Methicillin Resistance Staphylococcus aureus (MRSA) is the most important. The rate of MRSA is increasing worldwide. This is alarming because the danger of these organism in public health. Therefore the aim of this study was to determine the sensitivity of gram-positive cocci, as well as MRSA to vancomycin and other antibiotics.
Methods: This was a descriptive study, and were carried out on 300 patients with urinary tract infections (UTI) caused by gram-positive cocci, referred to Imam Khomeini hospital during eight months. Prior to the antibiotic sensitivity testing all the isolates were identified according to the standard conventional biochemical procedure, and then the antibiotic susceptibility test were carried out according to Bauer-Kirby method.
Results: Among the gram positive cocci causing UTI, the most abundant were Staphylococcus saprophyticus (37.7%), followed by Staphylococcus epidermidis (22.3%) and Staphylococcus aureus (18%) respectivley. The sex distribution of patients were 163 female (54.3%) and 137 male (45.7%) respectively, and the prevalence rate of urinary tract infections in female was (8.6%) higher than male. The rate of sensitivity of isolated Staphylococci were as followed, sensitive to vancomycine (100%), Ciprofloxacin (89.2%), rifampin (87.6%), and amikacin (71.8%) respectivley, but were resistant to penicillin and amoxicillin (100%). The antibiotic sensitivity rate of isolated Streptococci was to vancomycine (85.1%), ciprofloxacin (50.7%) and penicillin (79.1%) respectively.
Conclusion: Vancomycin is still a suitable antibiotic for the treatment of Staphyloco-ccus infections. Although 6% rate of enterococci resistance to vancomycin is alarming, and use of this antibiotic in the treatment of other gram-positive bacteria should be done with precaution.

Abstract
Background: The purpose of this study was evaluation of risk factors of peripheral artery disease (PAD) and effective markers on it.
Methods: This descriptive-analytical study was done during 2010-2011 in the surgical units of Khorramabad Shohada Hospital. Fifty patients who had symptoms of PAD undergoing CT angiography and biochemical markers for them were measured. The investigated variables were family history, site of arterial obstruction, underlying diseases, smoking history, physical activity and stress level. A control group was considered for the study. The comparison was made between these two groups.
Results: Aging showed a significant role in prediction of PAD (70% sensitivity and 64% specificity). Homocysteine had the highest sensitivity (80%) in prediction of PAD, compared with other biomarkers. CRP (74% sensitivity) was the best marker that had positive predictive value for PAD. Fasting blood sugar (FBS) showed a significant role in prediction of true positive cases of PAD (72% sensitivity and 74% specificity). HbA1C with 68% sensitivity and 64% specificity and TG with 50% sensitivity and 44% specificity could be considered as factors related with PAD.
Conclusion: The levels of C-Reacative protein, homocysteine, and FBS were correlated with PAD, HbA1C and TG levels were associated with PAD, but lower than the previously named markers. In this study a significant relationship between lipoprotein levels and PAD was also observed. PAD was associated with sex and age.

Abstract
Background: The aim of this study was to assess the association of serum adiponectin and a set of traditional cardiovascular risk factors with carotid artery intimal-medial thickness (CIMT) and coronary artery calcium score (CACS), as markers of subclinical atherosclerosis in subjects with early type 2 diabetes mellitus.
Methods: Carotid artery intima- media thickness (measured by B-mode ultrsonography), coronary artery calcium score (determined by high resolution computed tomography), serum adiponectin, Fasting blood sugar, serum lipids, body mass index (BMI), systolic blood pressure, diastolic blood pressure and mean arterial pressure were measured in 123 asymptomatic newly diagnosed cases of type 2 diabetes mellituss and 152 age and sex matched healthy control subjects.
Results: Serum adiponectin and lipids were significantly lower in those with type 2 diabetes mellitus (P<0.01). Left, right and mean carotid artery intima- media thickness, coronary artery calcium score, fasting blood sugar, systolic blood pressure, diastolic blood pressure and mean arterial pressure were significantly higher among diabetic patients compared to healthy controls (P<0.05). Mean carotid artery intima- media thickness was positively and independently related to age (P<0.001) and triglyceride (P=0.01) in diabetic group. Coronary artery calcium score was associated positively with age (P=0.004) and inversely with high density lipoprotein (HDL) cholesterol (P=0.002) among diabetics.
Conclusion: Although adiponectin was lower in diabetics compared to controls, it had no significant association with carotid artery intima- media thickness and coronary artery calcium score as markers of subclinical atherosclerosis. In patients with type 2 diabetes in addition to age, serum triglyceride levels are correlated with carotid artery intima- media thickness, while HDL cholesterol is inversely correlated with coronary artery calcium score.

Abstract
Background: Hydatid disease or echinococcosis is a common parasitic disease of human and bovine, caused by infection with larva of the cestode echinococcus. Liver is the most common organ that is involved in this disease. Pelvic involvement and neurological symptoms, due to mass effect of pelvic involvement, in lower extremities are very uncommon manifestations of the disease.
Case presentation: A forty six year old man was referred to clinic of surgery at Ghaem Hospital, Medical University of Mashhad, Iran. The patient complained about weakness and motor impairment in right lower extremity accompanied by numbness and radicular pain over past two months. Physical examination demonstrated muscular atrophy and reduced muscular strength in right lower extremity. Computed tomography and ultrasonographic studies showed a cystic mass in right side of the pelvic cavity with extention to the sciatic notch and another cystic mass in right gluteal region. Surgical operation revealed a cystic mass deep in pelvic cavity with the extention to the right sciatic notch with compression of nerve roots. The cystic mass was contained of daughter cysts which confirmed the diagnosis of hydatid cyst disease. This diagnosis was confirmed by pathologic assessment.
Conclusion: Although uncommon, but hydatid disease can involve the pelvic cavity and make a pelvic, usually cystic, mass that can make compression on nerve roots and so making neurologic symptoms in lower extremities. So in endemic areas for hydatid disease, such as Iran, pelvic hydatid cysts should be considered as a possible differential diagnosis in patients presenting with the sciatic pain and neurological manifestations in whom a pelvic mass has been found too.

Abstract
Background: Lack of precise diagnostic criteria and sufficient findings in support of biopsy sampling during upper gastrointestinal endoscopy is one of the special challenge in endoscopy assessment in Barrett's esophagus. The aim of this study was to evaluate the mucosa in the distal esophagus tissues through a biopsy during upper gastrointesti- nal endoscopy in gastroesophogeal reflux disease patients whose symptoms don't im- prove or only partially resolve with treatment.
Methods: A cross-sectional study was done in patients with gastroesophogeal reflux disease medically resistant to treatment. The patients were assessed by gastroenterology department in Sina Hospital, Tehran, Iran, since September 2012 to September 2013. Patients with coagulopathy, esophageal varicose, esophageal cancer, earlier detection of developing Barrett's esophagus, history of irritable bowel syndrome, psychological dis- orders and using of nonsteroidal anti-inflammatory drugs (NSAIDs) such as aspirin, were excluded. Esophageal squamous epithelium and cylindrical tissue of stomach was carefully checked by endoscope. Then 2 to 4 biopsy of the Z-line above the gastroe- sophageal mucosa were obtained.
Results: One hundred and fifty three patients included 78 men (51%) and 75 females (49%) with a mean age of 47.92±17.57 years participated in the study. The mean of body mass index of patients was 25.05±4.17 kg/m2 and body mass index in 45.8 % of the patients more than 230 kg/m2. Biopsy specimens were taken in 31 cases were not enough for histological examination. In other patients, 25 cases (20.5%) were normal and 97 cases (79.5%) had the following pathological diagnosis: mild esophagitis (49 cases 40.2%), moderate esophagitis (24 cases 19.7%), severe esophagitis (14 cases
11.5%), Barrett's esophagus (8 cases, 6.5%), fungal esophagitis (1 cases, 0.8%), and eosinophilic esophagitis (1 cases 0.8%). 117 patients (76.5%) had H. pylori infection. Sensitivity and specifity of endoscopy for detection of Barrett's esophagus during upper gastrointestinal endoscopy were 100% and 84.13% (CI 95%:78.53-89.09%), respec- tively.
Conclusion: Our data showed that doing of accurate and adequate biopsy samples from lesions in upper GI endoscopy can be helpful in the diagnosis of Barrett's esophagus

Abstract
Background: Controlling parenchymal hemorrhage especially in liver parenchyma, despite all the progress in surgical science, is still one of the challenges surgeons face saving patients’ lives and there is a research challenge among researchers in this field to introduce a more effective method. This study attempts to determine the haemostatic effect of aluminum chloride and compare it with that of the standard method (simple suturing technique) in controlling bleeding from liver parenchymal tissue.
Methods: This is an experimental study. In this animal model study 60 male Wistar rats were randomly allocated into six groups and each of which contains 10 mouse. An incision, two centimeters (cm) long and half a cm deep, was made on each rat’s liver and the hemostasis time was measured once using aluminum chloride with different concentrations (5%, 10%, 15%, 25%, and 50%) and then using the control method (i.e. controlling bleeding by simple suturing). The liver tissue was examined for pathological changes. Finally, the obtained data were entered into SPSS software and analyzed using Kruskal- wallis test, Mann- Whitney, Kolmogorov- Smirnov test.
Results: The mean time to hemostasis in groups of aluminum chloride concentration of 50%, 25%, 15%, 10% and 5% were respectively, 8.90, 13.10, 23.30, 30.30 and 37.8 seconds, also in the control group (suture) mean time of hemostasis was 60/81 seconds. The haemostatic times of different concentrations of aluminum chloride were significantly less than that of the control group (P< 0.001). There was a statistically significant difference between every two haemostatic times (P< 0.001). The pathologic examination showed the highest frequency of low grade inflammation based on the defined pathological grading.
Conclusion: Aluminum chloride compare to the control method (i.e. controlling liver bleeding by simple suturing) needs less time to control liver bleeding. Aluminum chloride is an effective agent in controlling liver hemorrhage in an animal model.
