Abstract

The Turkmans are one of the Iranian ethnic population. HLA typing (class I and II) was performed in this population. The data obtained from this study was compared with different populations of the world. We observed that the Turkman population is most similar to the Northern chinese and Uigur population. The distributions of HLA antigens in Turkmans are somewhat between Iranian population, Northern chinese and Uigur population. Natural selection and gene alteration select the people who could better adopt themselves with new conditions. Investigation of Turkman's HLA in comparison with Iranian's HLA reveals more details in genetics of Behcet's disease. Behcet's disease is very rare in Turkmans (index 0.5) whereas its frequency is high in other Iranians and Northern chinese. Distribution of susceptible antigens like B5 is the same in Turkmans and Northern chinese (19.5%) but much higher in other Iranians, whereas B35 have almost the same distribution in Turkmans and Iranians (37% and 33% respectively). DQW1 and CW4 antigens which were suspected to have a negative association with Behcet's disease are the most frequent antigens in Turkmans.

Abstract

Introduction: Occupational exposure to carbon, silica, and quartz, particles are known predisposing factors for bronchial anthracosis. In some cases bronchoscopy may reveal anthracosis infection to be associated with mycobacterium tuberculosis.

Materials and Methods: In a prospective study, from 1999 and 2001, 919 patients underwent diagnostic bronchoscopy for pulmonary diseases.

Results: Of these, 96 patients had some evidence of anthracosis infection. Twenty-six (27%) of these patients had positive smears or cultures for mycobacterium tuberculosis and only eight (8.3%) patients with positive history of occupational exposure. In the other 70 patients 29 had previous occupational exposure, and 41 stated no previous exposure.

Conclusion: Our findings show a significant association of tuberculosis with anthracosis however further studies are needed to document an etiologic relationship.

Abstract

Background and Aim: Spasticity is a velocity-dependent increase in tonic stretch reflexes (muscle tone) with exaggerated tendon jerks, resulting from hyperexcitability of the stretch reflex. The measurement of spasticity is necessary to determine the effect of treatments. The Modified Ashworth Scale is the most widely used method for assessing muscle spasticity in clinical practice and research. The purpose of this study was to investigate the interrater reliability of Modified Ashworth Scale in hemiplegic patients.

Materials and Methods: Thirty subjects (16 males, 14 females) with a mean age of 59.40 (SD =14.013) recruited. Shoulder adductor , elbow flexor , wrist dorsiflexor , hip adductor , knee extensor and ankle plantarflexor on the hemiplegic side were tested by two physiotherapists.

Results: In the upper limb, the interrater reliability for shoulder adductor and elbow flexor muscles was fair (0.372 and 0.369, respectively). The reliability for the wrist flexors was good (0.612). The difference in Kappa value for the proximal muscle (shoulder adductor 0.372) and the distal muscle (wrist flexor 0.612) was significant (²X=33.87, df=1, p<0.05). In the lower limb, the reliability for the hip adductor was fair (0.350), but for the knee extensor and ankle plantar flexor was moderate (0.518 and 0.542, respectively). The Kappa value for the proximal muscle (hip adductor: 0.350) and distal muscle (ankle plantar flexor0.542) had no significant difference (²X =1.35, df=1, p >0.05). The mean value for the upper limb (0.505) and the lower limb (0,.516) was not significantly different (²X=0.1407, df=1, p>0.05).

Conclusion: The interrater reliability of Modified Ashworth Scale was not good . The limb, upper or lower, had no significant effect on the reliability. In the upper limb, the reliability for the proximal and distal muscle was significantly different. However. The difference in the lower limb was not significant.When using the scale, one should consider it&aposs limitation.

Abstract

Background and Aim: The better understanding of immunopathologic mechanism of tuberculosis (TB) is necessary for the production of new vaccines and adjunctive immunomodulator drugs. Intended to this object, the following study including the measurement of serum concentrations of Th1 (Interferon (IFN)-y and interkeukin (IL)-2 and Th2 cytokines(IL-4AND IL-10 ) in patients with sputum smear-positive pulmonary TB and comparisons of them with PPpositive healthy persons, was designed.

Materials and Methods: The HIV-negative patients that had sputum smear-positive pulmonary TB as defined WHO criteria and hospitalized in the infectious diseases ward of Imam Khomeini hospital or referred to health care centers in the south of Tehran, were included in the study. The PPD-positive healthy persons who were close contacts with pulmonary TB patients, were considered as control group.

Results: In this research 34 active pulmonary TB patients (including17men and 17 woman)and 23 healthy persons with PPD skin test results  or = 10mm (including 12men and 11 woman) were studied. The mean ages of the patients and the healthy persons were 73 and 41 years and 74 and 27 years, respectively. The mean serum IFN-Y concentration was significantly higher in TB patients but the mean serum IL-2 IL-4and IL-10 concentrations were significantly higher in healthy persons. The com parison of the mean serum levels of these cytokines before and during treatment (about 2 months after starting treatment) showed that the amounts of IFN-y and IL4 were increased and the amounts of IL2 and IL-10 were decreased but only the changes of IL-10 were statistically significant. There were no effect on the cytokine changes before and during treatment by age and gender of the patients.

Conclusion: The results of the study of serum Th1 and Th2 cytokines in pulmonary TB patients were different in comparison with the results of the studies of peripheral blood mononuclear cells (PBMCs) stimulated with M.tuberculosis antigens. SO, the simultaneous measurement of them in serum, pleural fluid, BAL fluid and the medium culture of PBMCs stimulated with the antigens is recommended.

Abstract

Background: The outcome of acute hepatitis B infection may be influenced by host genetic factors like human leukocyte antigen (HLA). To investigate the association between the HLA-DRB, DQA1 and DQB1 alleles and chronic hepatitis B infection, 50 patients with chronic hepatitis B (based on 6 months positive of HBsAg and HBc antibody and HBeAg and antibody by serological test), were selected from Turkman population in north east of Iran .Allele frequency in patients were compared with a 65 aged and sex match control group from healthy blood donor of that ethnic population.
Methods: HLA DRB, DQA1 and DQB1 alleles were determined using polymerase chain reaction based on sequence specific primer (PCR-SSP) method. Allele frequencies in patients and control subjects were compared by Epi-info statistical soft-wear.
Results: There was a significant increase and positive association in HLA-DRB1*0301, DQA1*0501 and DQB1*0604 allele frequency in patients group while the frequency of HLA-DRB1*1301, 1501 and DQB1*0401 and DQA1*0401, 0102 were lower in patients than control group and shows negative association.
Conclusion: In Iranian Torkman population, HLA DRB1*0301, DQA1*0501 and DQB1*0604 have an important role in susceptibility to chronic hepatitis B infection and HLA DRB1*1301, 1501, DQB1*0401 are associated with protection to chronic hepatitis B infection. Larger case control studies may be helpful to confirm our investigation.

Abstract

Background: There is considerable professional debate over which technique is the best for lifting. The aim of this study is to compare three static lifting styles, the stoop, semi-squat and arm lift, using maximum isometric voluntary contraction (MIVC) as one indicator for recommending a lifting style.
Methods: Thirty healthy women (mean age: 22.37 years) participated in this quasi-experimental study. They performed the tests in static postures by standing on the platform of the Lift TrackTM and pulling the dynamometer of the instrument with maximum effort in three lifting styles: the stoop, semi-squat and arm lift. The subjects warmed-up by practicing the lifts first. The mean MIVC from the two other sets of lifts were used for statistical analysis by repeated measurements and SPSS (ver.10) software.
Results: There were significant differences between the MIVC of the three lifting styles in this study. The largest MIVC was for the semi-squat lift and was the least was for the arm lift (p<0.001). The MIVC of the stoop lift was larger than that of the arm lift (p<0.001).
Conclusion: The largest MIVC for the semi-squat lift suggests that this style is useful for lifting objects from the floor. The differences in biomechanical and muscle pattern activity changes could explain these results. It seems that activation of the quadriceps muscles in the semi-squat lift was a main factor for producing more MIVC, so when this style is recommended for lifting, attention to the power of the quadriceps is important.

Abstract

Background: Pin loosening and infection in skeletal traction are important problems in orthopedic surgery and methods which are usually used to manage these problems, are costly and sometimes complicated. In this study, the efficacy of using cast support in infection and loosening of proximal tibial pin was investigated.

Methods: In a randomized clinical trial, 60 patients referring to Rasul-e- Akram hospital from 1383 to 1384, who needed to have proximal tibial pin for at least one month, were studied. All patients were treated with oral antibiotic until 24 hours after pin insertion. Depending on using cast support or not, they were randomly categorized into two groups (30, 30). The rate of pin loosening and infection between these two groups were compared.

Results: In the group without cast support infection rate was about %26.7 while this rate was %13.3 in the group with cast support, which means no significant difference (.33). In addition, although the rate of loosening in the group without cast support was more than the other group, it had no statistical meaning. (%20 compared with %10, p= 0.47)

Conclusions: Cast support doesn't affect the rate of pin loosening and pin site infection. However, considering correct technique for pin insertion including prevention of thermal injury and local hematoma is very important. Therefore, the use of cast support is an optional choice up to surgeons' preference.

Normal 0 false false false EN-US X-NONE AR-SA MicrosoftInternetExplorer4 Background: Oropharyngeal candidiasis is the most frequent fungal infection in HIV patients. The aims of this study were to appraise prevalence of oropharyngeal candidiasis and to determine factors associated with oropharyngeal candidiasis and oral yeast colonization among Iranian HIV patients.
Methods: The patients were composed 150 Iranian HIV positive individuals referred to Iranian Research Center for HIV & Aids (IRCHA), Imam Khomeini Hospital complex in Tehran, Iran. Oral samples were obtained and cultured on mycological media. TCD4 lymphocyte count/percentage was measured and patients were categorized. Patients evaluated for some risk factors for oropharyngeal candidiasis and oral candida colonization.
Results: Fifty nine percent of patients were presented with oropharyngeal candidiasis and the carriage rate of yeasts was 116 (77.2%). The most frequent isolated candida species were Candida albicans (102) 50.2% and Candida glabrata (45) 22%. Thrush in 57(38%), perleche in 30(20%) and erythematous lesions in 7(4.7%) of patients were observed. Significant differences in TCD4 count (p=0.01), gender (p=0.02), antifungal therapy (p=0.001), smoking (p=0.02), and intravenous drug use (p=0.03), between asymptomatic and symptomatic patients were observed.
Conclusion: Oral candidiasis is a frequent complication among Iranian HIV individuals. C. albicans and C. glabrata are most important etiologic agents of oral candidiasis. In Iranian HIV individuals TCD4 count, antifungal therapy, gender, smoking and intravenous drug use are important risk factors for oropharyngeal candidiasis. Denture wearing and age are predisposing factors for oral colonization.

Background: With respect to the importance of hepatitis B vaccination of high-risk groups such as prisoners, this study was performed to assess the comparability of a short-course double-dose vaccination schedule with the standard 3-dose schedule.
Methods : Within a randomized clinical trial, a short-course vaccination (at months 0 and 1) with 20 microgram (double-dose) doses of the vaccine was compared to the standard method of hepatitis B vaccination (at months 0, 1 and 6, with 10-microgram doses) in 100 prisoners in Zahedan city in Iran in 2009. We made sure the sera from all the individuals were negative for markers of previous hepatitis B infection. Subsequently serum from all the participants was tested for anti-HBs antibody 1, 2 and 7 months after the first dose of vaccination.
Results : Seroconversion rates (HBsAb>10 mIU/ml) 1, 2 and 7 months after the first dose of vaccination were similar in the routine (11%, 79% and 94%, respectively) relative to the double-dose group (26%, 95% and 93 %, respectively). The mean values of anti-HBs antibody titers were similar in the 1st and 2nd months for the two groups but it was significantly higher (P=0.002) in the routine dose (514 mIU/ml) versus the double-dose group (130 mIU/mL), in the 7th month.
Conclusion: Demonstrating comparable results with the standard 3-dose schedule, it seems that short-term double-dose vaccination for hepatitis B is a safe and acceptable method for use in high-risk groups such as prisoners.

Abstract

Background: Deposition of bilirubin in neurons causes permanent neuronal injury. Bilirubin exhibits an affinity for the phospholipids of plasma membrane like N-methyl-D-aspartate (NMDA) receptors. Magnesium is an NMDA antagonist and it acts against the neurotoxic effects of bilirubin. We compared pre- and post-phototherapy serum magnesium level of neonates with hyperbilirubinemia to find the best time of discharge and evaluate new management techniques such as magnesium supplementation.

Methods: In this semi-experimental study, we evaluated neonates admitted in Ali Asghar Children's Hospital in Tehran, Iran with signs of icter from 2009 to 2010. The inclusion criteria included age less than four weeks, no history of magnesium sulfate administration in the mother and absence of sepsis.

Results: From 106 patients with icter, 50.9% were male and 49.1% were female neonates. Their mean gestational age was 37.341.286 (33-41) weeks and the mean birth weight was 3172.12436.936 (2022-4300) grams. The frequency of underlying causes of hyperbillirubinemia included: ABO mismatch 9.34%, Rh incompatibility 4.7%, breastfeeding 16% and breast milk 44.3%. There was a significant difference (P≤0.001) between serum magnesium levels before (2.24mg/dl) and after phototherapy (2.12mg/dl). There were no significant differences between serum magnesium values in the two sexes (male=2.28, female=2.19), among different gestational age groups (<34 wks=2.35, 35-37 wks=2.27, >38 wks=2.17), between different birth weight groups (1500-2500 g=2.4 and >2500 g=2.23) or severity of hyperbilirubinemia (mild=2.23, moderate=2.21 and severe=2.29).

Conclusion: Phototherapy decreases the total magnesium concentration and magnesium administration will prevent bilirubin neurotoxicity in icteric neonates.

Abstract

Background: Fumonisins, a family of mycotoxins, are mainly found in wheat, corn and their products. Previous studies have shown that fumonisin B1 (FB1), the most abundant and toxic of known fumonisins, has been associated with many animal and human diseases including cancer. In the present study, the effects of FB1 were examined on the production of inflammatory cytokines in intestine and stomach cell lines.

Methods: This study was performed in the Cancer Research Center of Tehran University of Medical Sciences in 2010. The cell lines of colon adenocarcinoma (SW742) and gastric epithelium (AGS) were purchased from the Pasteur Institute of Iran. The cells were pretreated with different concentrations of FB1 (0 to 100 µM) for 3 days. The cells were later stimulated by lipopolysaccharides. Twenty-four hours after cell induction, the cytokines including tumor necrosis factor-alpha (TNF-α), interlukin-1 beta (IL-1β) and interlukin-8 (IL-8) were measured by ELISA.

Results: Treatment with FB1 induced a dose-dependent decrease in IL-8 production (P<0.05). This decrease was seen in both SW742 and AGS cell lines. Moreover, FB1 induced a dose-dependent increase in the production of TNF-α and IL-1β in both cell lines (P<0.05).

Conclusion: The results of this study indicated that FB1 could increase the inflammatory cytokines including TNF-α and IL-1β in gastric and intestinal celllines. These effects might result in the development of inflammatory responses and subsequent mucosal atrophy in in-vivo conditions.

Abstract

Background: Oropharyngeal candidiasis and antifungal drug resistance are major problems in HIV positive patients. The increased reports of antifungal resistance and expanding therapeutic options prompted the determination of antifungal susceptibility profile of Candida species isolates in Iranian patients living with HIV/AIDS (PLWHA) in the present study.

Methods: One hundred fifty oral samples from Iranian HIV positive patients were obtained and cultured on CHROMagar and Sabouraud's dextrose agar. All isolates were identified according to assimilation profile, germ tube, colony color and other conventional methods. Disk diffusion testing and Broth Microdilution of six antifungal agents were performed according to the methods described in CLSI.

Results: Candida albicans (50.2%) was the most frequent isolated yeast, followed by C. glabrata (22%). Non-Candida albicans species were isolated from 71 (61%) positive cultures. 25.7% of Candida albicans isolates were resistant to fluconazole (MIC≥64 µg/ml) as were 21.9% and 16.4% to ketoconazole and clotrimazole (MIC>0.125 µg/ml), respectively. Resistance to polyene antifungals including amphotericin B and nystatin, and caspofungin were scarce. 57.7% of candida glabrata isolates were resistant to fluconazole, 31% to ketoconazole and 35% to clotrimazole.

Conclusion: Screening for antifungal resistant candida isolates by disk diffusion or broth dilution methods in clinical laboratories is an ideal surveillance measure in the management of oral thrush in patients with HIV/AIDS. Although nystatin is widely used in clinical practice for HIV positive patients, there was no evidence of enhanced resistance to it. Regarding no resistance to caspofungin, its administration is suggested.

Abstract

Background: Measurements of mitral valve area (MVA) are essential to determine the severity of mitral stenosis (MS) and adopt the best management strategies. The aim of the present study was to compare MVA determined by two-dimensional (2D) planimetry to MVA measured by continuity equation (CE) in patients with moderate to severe MS.
Methods: We evaluated 73 consecutive patients with the diagnosis of MS scheduled for balloon mitral valvuloplasty or with moderate to severe rheumatic MS admitted at the echocardiography clinic of Imam Khomeini Hospital in 2010. Using 2D images of mitral valve obtained from paraesternal short axis view, 2D planimetry of the mitral orifice area was performed by an experienced cardiologist. MVA by CE was calculated from aortic forward stroke volume divided by transmitral time-velocity integral.
Results: The mean value of MVA by 2-D planimetry was 1.0±0.3 cm2. The average values of MVA measured by PHT and CE were 1.0±0.3 cm2 and 0.9±0.4 cm2, respectively. The MVA determined by planimetry correlated well with CE (r=0.832, standard error of estimation [SEE]= 0.166, P<0.001). The mean values of MVA calculated by CE highly correlated with those calculated by 2-D planimetry in patients presenting with both non-significant (r=0.701) and significant (r=0.761) AIs.
Conclusion: When planimetry is not feasible, such as in severe calcification of mitral valve or after percutaneous balloon valvuloplasty, CE could be an alternative method for MVA measurement in comparison with PHT.

Abstract

Background: McGill pain questionnaire is the most useful standard tools for assessing pain. McGill pain questionnaire contains 78-word descriptive of the 20 subclasses form-ing in three main sensory, affective and evaluative domains. Due to cultural differences, the questionnaire has been translated into several languages. This study aimed to transl-ate MPQ into Persian language and assess its reliability, validity and acceptability in patients with cancer.
Methods: The study performed in Medical Oncology Department of Cancer Institute in Imam Khomeini Hospital in the Spring 2012. After translation of MPQ by two experts fluent in English, Persian version was returned to English. Then that backward transla-tion was compared with the original questionnaire and words that did not match were reviewed.  Patients with different types of cancer who suffering from chronic pain were admitted in our study. They did not receive any kind of pain killer drugs during the pre-vious 24 hours. There was no restriction of age, sex, education, type of cancer or treat-ment modality. The reliability and validity of Persian-McGill pain questionnaire after interviewing patients was assessed by test–retest reliability and internal consistency (Cronbach’s alpha).
Results: In total, 84 patients were interviewed and 30 patients who were available after 24 hour with the same condition recomplete the questionnaire. Cronbach’alpha of each domain was in 0.622-0.743 and total Crobach’s alpha (n=84) was 0.85. Evaluative aspect has only one subgroup and because of this, it is not have Crobach’s alpha. The stability coefficient (n=30) in all areas (sensory, emotional, and other domains) were 0.812-0.964. Stability coefficient among the 20 Persian McGill Pain Questionnaire (PMPQ) subclasses showed significant and reliable relationships over time for all groups.
Conclusion: This study is the first study that assessed psychometric properties and use-fulness of the MPQ in Iranian patients with cancer, showed that it is a potentially useful measure with a high validity and reliability standards.

Abstract

Background: Today, a CT scan examination play an important role in disease diagnosis and thus allocates a significant dose of medical X-ray examinations. One of the important principles in the use of ionizing radiations is to observe radiation protection principles. Evaluating patient's absorbed dose and implementing the strategies for reducing dose are prior in safety issues. To achieve this purpose, sufficient studies should be performed in this regard. Therefore, patient's absorbed dose and the factors affecting have been studied in this research. This study aims to present and develop an acceptable level of absorbed dose in CT scan examinations.
Methods: Diagnostic reference dose level in the adult age group (older than 15 years) has been studied in eleven CT scan centers in Tehran. For this purpose, CT scan examinations prevalent in above-mentioned centers were chosen and Weighted Computed Tomography dose index (CTDIw) and dose length product (DLP) parameters were studied. Standard phantoms with 16 and 32 diameters of Polymethylmethacrylate (PMMA) origin have been used in the centers for CT scan calibration process. CTDIw third quartile has been considered as the diagnostic reference dose level (DRL).
Results: Rate of diagnostic reference dose in the adult age group (older than 15 years) for the head, sinus, lungs, abdomen and pelvis are 50.87, 38.27, 8.05 and 9.11 mg, respectively. Dose measurements made in this survey have been used to set up local DRLs and can be used as a template for national DRLs.
Conclusion: Value of diagnostic reference dose for the head examinations is more than the other parts and diagnostic reference dose in Tehran city in the Adult age group and the protocols compared is less than national reference dose.

Abstract

Background: On of the most common gasterointrestinal disease is gallstone disease and it`s prevalence is 11%-36%in autopsies. If gallstone leads to symptoms and side effect cholecystectomy will be inevitable. Gastric infection due to H.P will cause several symptoms of which dyspepsia and epigastric pain are outstanding .Gall stones also usually causes epigastric and/or right upper quadrant pain. Pain in other abdominal quadrant is less common. In this study we investigated the coincidence of gall stone and gastro intestinal H.P regarding the common symptom, between these two conditions to prevent unnecessary operation.
Methods: The cases were adopted from cholecystectomy candidates due to gall stone disease (proved by ultrasonography). The control group were normal people who proved to be gall stone free ultrasonographicly. Serum IgG anti H.P was checked and compared between the two groups.
Results: Seventy percent of patients entered into the study which consisted of 35 case and 35 controls. The two groups were not significantly different in age and gender. There were 22 (68.8%) and 10 (31.2%) H.P positive cases in case and control groups respectively. Thirteen (34.2%) and 25 (65.8%) cases were H.P negative in case and control groups respectively. Comparing these results will reveal a statistically significant difference (P=0.004).
Conclusion: The relationship between gastric H.P and gall stone in this study supports the role of H.P in gall stone formation. According to our results and the common symptoms of two conditions specially in atypic biliary colic, it seems that in many cases gastrointestinal H.P causes the pain. Prospective studies are recommended.

Abstract

Background: Polycystic ovary syndrome (PCOS) is the most common endocrine disorder in women of reproductive age. Chronic infections have been mentioned as one of the different etiologic factors related to PCOS. Due to the high prevalence of Helicobacter pylori infection especially in developing countries, its probable role in the pathogenesis of PCOS and the limited information available in this area, serologic study of H.Pylori infection in patients with PCOS, was performed. Methods: This research was performed as a case control study from Dec 2010 until May 2012 in 82 patients (and their spouses) with polycystic ovary syndrome (case group) and 82 non PCOS patients (control group) with an age range of 20-40 referred to Vali-e-Asr Hospital infertility clinic. Both groups and their husbands filled a questionnaire and were examined by testing their serum H.Pylori IgG and IgA antibody levels. Statistical testing and analysis was performed by t-student and λ2 tests. Results: Mean age of the women and men and also other demographic characteristics except their profession showed no significant difference (P>0.05) in the two groups (PCOS and non PCOS). H.Pylori antibody IgG serum level was positive in 78% and 76.5% and H.Pylori antibody IgA level in 30.5% and 37% of PCOS versus non PCOS patients respectively which showed no statistically significant difference (P>0.05). There was also no significant difference between the H.Pylori antibodies levels in the spouses in the two groups (P>0.05). Conclusion: This study showed no significant difference in serologic examination re-sults in PCOS versus non PCOS patients. The finding of high prevalence of H.Pylori IgG and IgA positive levels in both PCOS and non PCOS patients can be probably re-lated to the high prevalence of H.Pylori infection or exposure in Iranian population and therefore suggest an issue for further investigation.
