Abstract
Epilepsy is a disease with high prevalence, which interferes driving and may lead to car accident This case-control study has been done on 100 epileptic patients and 100 persons as control group, who had history of driving. We gathered our patients with face to face interview and registering their information in special forms which were prepared for this study. There were three times more accidents among epileptic cases comparing with control group and this difference was more considerable in men and in patients under 35 years old. The cause of accident were not seizure attack in more than 60% of the patients and these ordinary accidents were also more in case group. Epileptic patients with history of car accidents during driving had poor drug compliance comparing with the epileptics without history of an accident so drug compliance may be valuable in predicting accident in these patients. We have also found poor drug compliance in whom seizure attacks caused accident for them. 58% of the epileptics had not consulted their physician about driving. 43.3% of seizures during driving were of generalized type and none of the patients had inform police about their disease during getting driving license.

Abstract
Background: Nowadays, aromatic hydrocarbons such as benzene, toluene, and xylene are extensively used in the different environments and industries, causing adverse effects on individuals who are being exposed occupationally and environmentally to these hazardous compounds. In this study, occupational exposure to xylene in workers, employing at pathology wards of hospitals belonging to the Qazvin University of Medical Sciences have been investigated.
Materials and Methods: Methyl Hiporic Acid (MHA) as a main metabolite of xylene in urine was used to evaluate the workers exposure to this chemical. The urine samples were taken from all 30 workers from 4 hospitals, i.e. Kosar, Shahid Rajaei, Booali and Qods. Through this study, 30 administrative employees were also selected as control group. The direct DBA colorimetric method was used to measure MHA in the workers urine.
Results: The results obtained from this study showed that, there were significant differences between MHA and working days, type of jobs, and length of exposure time. This study also showed that, there were no significant differences between urinary MHA concentration and sex, age, and smoking habit.
Conclusion: Through this study, it was also clearly obtained that, xylene exposure can not affect on the total and direct serum bilirobin in the workers blood. Finally, it is worth mentioning that, although this study showed no acute exposure to xylene in hospitals pathology wards, the effect of chronic exposure to such compound cannot be ignored, therefore protecting workers against like these organic solvents are strongly recommended as their TLVs are considerably being reduced during these years

Abstract
Background: Because of eventual side effects of chemical drugs, the efficacy of natural wound healing accelerators in long-term diseases and some situations is demanded to practitioners. The initial aim of our study was to assess full thickness excisional skin wound healing and inflammation diminution, Morphometrically and Histopathologically, after topical application of dried extract of Echinacea purpurea aerial part in rats, compared with zinc oxide.
Methods: Sixty wistar rats received four full thickness excisional wounds with the aim of surgical punch on the back skin under surgical anesthesia. All rats were randomly divided into groups 1, 2 and 3, of Echinacea purpurea, zinc oxide and control, respectively. All of them were treated topically once a day for 21 uninterrupted days. Healing of the wounds was daily measured by taking digital photographs and analysis. Histopathologic assessment was carried out in the 0th, 3rd, 7th, 14th, and 21st days of treatment period as well, and wound healing was assessed using 1 to 6 healing grades.
Results: According to Morphometric findings, the wound contraction rate in group 1 after 21 days of skin punching, with wound size of 0.18±0.03 mm2 in contrast with group 2, 2.81±0.21mm2, was much higher than that in other groups. Group 1 with wound contraction rate of 2.5 times in the day 7 and 3 times in the day 14 more than group 2, had the best wound contraction (p<0.01). histopathologic assessment revealed that, overall healing rate in the group 1 was highest (p<0.01).
Conclusion: Echinacea purpurea dried herbal extract could be a new capable remedy to accelerate skin wound healing because of its potential anti-phlogosis and wound healing stimulatory properties.

Abstract
Background: The clinical importance of yeast infections has increased in recent decades. There are 10-15 pathogenic Candida species. The current morphological and physiological methods for identification of Candida species are generally not easy to interpret and may be expensive or time-consuming. In the present study, we introduce and use a new approach for the identification and differentiation of medically important yeast species of Candida. In this method, size polymorphism of the internal transcribed spacer regions, ITS1 and ITS2, of the ribosomal DNA in various Candida species is used as the basis of species recognition.
Methods: The genomic DNA of 31 standard strains and 60 clinical isolates was extracted and PCR-amplified using two primer pairs (ITS1-ITS2 and ITS3-ITS4) separately. Both PCR products were mixed and analyzed after standard agarose gel electrophoresis. The species of the tested yeasts were identified by the electrophoretic patterns of the mixed PCR products of each sample, comparing the data obtained from the sequence analyses of ITS1 and ITS2 molecules.
Results: By this method, with the exception of C. albicans and C. dubliniensis, we were able to clearly differentiate nearly all common pathogenic Candida species, including C. albicans, C. glabrata, C. gulliermondii, C. parapsilosis, C. tropicalis, C. krusei, C. kefyr, C. lusinaniae and C. rugosa. All standard and clinical strains were identified correctly, without expensive methods such as sequencing and capillary electrophoresis.
Conclusion: It seems that the PCR-FSP method introduced in this study is the easiest molecular approach for the identification of a wide range of pathogenic Candida species and is applicable for diagnostic and epidemiological purposes in reference laboratories.

Abstract
Background: One of the most important components of coronary
artery bypass graft surgery is need for blood transfusion that increases
morbidity and mortality. The aim of this study was to evaluate the factors
affecting the need for blood transfusion during off pump coronary artery bypass
(OPCAB)
surgery.
Methods: In
this descriptive case control study 923
patients who had undergone OPCAB at Afshar Hospital in Yazd,
Iran, from July 2008 to January 2010
were evaluated. The data was gathered from their records and was analyzed.
Results: 54% of
male and 79% of female patient need
blood transfusion. Mean age in patients needed transfusion was 61.58±11.11
years and in other group was 60.27±10.98
years of the patients that needed transfusion (p= 0.08). 563
(61%) of the patients needed transfusion with the
average of two units. The need for blood transfusion was higher in female
gender (p< 0.0001),
low hematocrit (p< 0.0001),
diabetes (p< 0.001),
hypertension (p< 0.025)
and multiple grafts (p< 0.027).
There were no significant differences in preoperative hemostasis tests,
affection to hyperlipidemia, CVA or
renal failure, antiplatelet drug administration and the application of left internal
mammary artery between the transfusion and non transfusion groups.
Conclusion: In this study preoperative
hematocrit was most important risk factor in transfusion in patients that
underwent OPCAB. Female gender, preoperative
low hematocrit, multiple grafts, diabetes and hypertension increased the rate
of blood transfusion. According to the high prevalence of blood transfusion in OPCAB, considering factors that
affect the transfusion rate is essential.

Background: Proper drainage of the mediastinal and pleural spaces following Off-Pump Coronary
Artery Bypass (OPCAB) surgery is essential
for the prevention of pleural and pericardial effusions, cardiac tamponade and
late complications such as constrictive pericarditis. Drainage tubes themselves
may induce some complications which can negatively affect the result of the
surgery. In this study we assessed a new technique for chest drainage following
OPCAB.
Methods: In this clinical trial, 171 patients were
allocated to two groups. In the control group, the drainage technique included
one drain in the left pleural cavity and another in the mediastinum, while in
the case group the drainage technique included one drain in the left plural
and one in the right pleural cavity.
Results: The amount of drainage in the case group was more than the control group (p=0.001).
We found significant reductions in the incidence of arrhythmias in the case
group (p=0.005). While one patient (1.2%)
needed reoperation for bleeding control in the control group, no patients
needed reexploration in the case group (p=0.497).
The duration of hospital (p=0.022) and ICU
(p=0.002) stays was shorter in the case group.
Conclusions: Based
on the results of this study, changing the position of mediastinal drains in
patients undergoing OPCAB surgery and shifting it to
the right pleural cavity, reduces complications, such as arrhythmia and
pericardial effusion, aside from establishing a better drainage.

Abstract
Background: Infections caused by opportunistic yeasts such as Candida species,
Trichosporon, Rhodotorula and Saccharomyces have increased in immunocompromis- ed patients and their identification is crucial as intrinsic and acquired resistance of some yeast species to antifungal agents are on the rise. The aim of this study was to identify the organisms to the species level in order to suggest accurate and effective antifungal therapies.
Methods: In this study that carried out in Tehran, Iran in 2009, 200 patients with yeast infection were medically examined and clinical specimens were prepared for direct examination and culture on Sabouraud dextrose agar. Subsequently, the isolated yeast
colonies were identified using various tests including culture on Corn Meal agar with
Tween 80, CHROMagar Candida and casein agar. For the definite identification of organisms some biochemical tests were done based on carbohydrate assimilation by RapID Yeast Plus System kit, and, finally, a molecular method, PCR-RFLP, using Hpa II enzyme, was performed for the remaining unknown yeast species.
Results: A total of 211 yeast isolates were identified in 200 patients with yeast infections. The most frequent isolated yeasts were Candida albicans, 124 (58.77%), followed by Candida parapsilosis, 36 (17.06%), Candida tropicalis, 17 (8.06%),
Candida glabrata, 13 (6.16%), Candida krusei, 8 (3.79%), Candida guilliermondii, 2
(0.96%), Trichosporon, 3 (1.14%), Rhodotorula, 1 (0.47%), Saccaromyces cerevisiae, 1 (0.47%) and other yeast species, 6 (2.84%).
Conclusion: Nail candidiasis was the most prevalent type of yeast infection in the patients and Candida albicans was the most frequent isolated species from all clinical specimens.

Abstract
Background: Different studies have shown that despite the expanding number of antifungal agents, death rate caused by Aspergillus species has been increased during the recent decades due to drug-resistance occurrence, increased minimum inhibitory concentration (MIC) and cross-resistance among the isolated species. Regarding the lack of effective response to conventional treatments and antifungal susceptibility patterns of the most common isolated Aspergillus species, this study was undertaken to draw a clearer picture in the Iranian setting.
Methods: During 13 months from September 2009 to October 2010, 50 clinically isolated Aspergillus cases were identified based on the method described by Klich (2002) and their morphological features. Subsequently, their susceptibility test was carried out according to NCCLS- M38A broth microdilution method.
Results: We found that 7.5% of the isolated A. flavus with an MIC>2 µg/ml to amphotericin B were probably clinically resistant types, and 25% of them with an
MIC<8 µg/ml to itraconazole were less sensitive isolated species. The isolates were less
sensitive to voriconazole too. The MIC range of 9 strains of A. niger and the MIC of one strain of A. fumigatus had increased to all the three medications in comparison with similar foreign studies.
Conclusion: In this study we found that the MICs of most isolates were in the range of the reference strains and the MICs of some isolates were in the range of similar foreign studies. In some significant cases, the MICs were beyond the known ranges showing the lower sensitivity of Iranian isolates and their increased MIC patterns.

Background: In the last two decades, cryptococcosis has been gaining a distinct public
health importance due to the growing number of AIDS
cases. Considering the low sensitivity of direct examination with India ink and
culture, use of sensitive techniques is crucial in the diagnosis of cryptococcal
meningitis. Polymerase Chain Reaction (PCR)
can be used to directly detect Cryptococcus neoformans in CSF
samples to increase the diagnostic power in cases where conventional
methods are unable to detect the organism.
Methods : In this cross-sectional study, CSF samples were
obtained from 25 patients suspected of
having neurocryptococcosis. The patients were referred to the Medical Mycology
Laboratory of the School of Public Health affiliated to Tehran University of
Medical Sciences from March 2009 to February 2010.
Three different methods, direct India ink examination, culture and PCR
were used to evaluate the CSF samples. Two 102
and 106 of Cryptococcus neoformans dilutions in
1ml of CSF
were prepared and examined by the three methods. In PCR
method, two primer pairs were selected to amplify the Cryptococcus
neoformans URA5 gene. The sequences
of primers were for A, B, C and D
serotypes.
Results : Only in one case PCR, as well as direct
examination and culture were positive. All the other samples were negative in PCR,
direct examination or culture. Both CSF dilutions
were positive in the three tests in the mentioned patient and the positive
control.
Conclusion: PCR
method can efficiently identify both control and positive samples of Cryptococcus
neoformans.

Abstract
Background: Autograft is the best option in nerve defects when end-to-end repair can not sufficiently preserve nerve continuity. Theoretically, if the severed nerve is reversely grafted, it may prevent axonal growth into nerve branches, and larger amounts of axons will reach the target organ and more satisfactory results will be obtained. In this study we aimed to compare conventional versus reverse nerve grafting.
Methods: This study was performed in Animal laboratory of Hazrat Fatemeh Hospital from April till August 2011. We randomly divided 40 Wistar rats into two groups. We excised 1.5 cm of the right sciatic nerve and anastomosed it conventionally between the proximal and distal ends of the nerve in rats in group A and in a reverse manner in rats in group B. The rats’ footprints were recorded in the first and 16th weeks after surgery. In week 16, the grafted nerves were removed under anesthesia for pathological examination and axon count. Subsequently, the results were compared clinically by sciatic functional index (SFI) through footprint analysis and paraclinically by axon count. A p-value smaller than 0.05 was considered statistically significant.
Results: Conventional and reverse nerve grafting no had statistically significant differences in clinical assessment in the first and 16th weeks (P=0.87) post-surgically and also no difference in paraclinical assessment in week 16 (P=0.68).
Conclusion: We had no significant clinically or para clinically differences between two approaches. It should be considered that the diameter and length of nerves and muscles in human is larger than rats, so the results of nerve repair may differ in human. We suggest a study in animal model which is anatomically more similar to human.

Abstract
Background: The etiologic role of Malassezia furfur in onychomycosis, because of its controversial keratinolytic ability, has not been proven. The most reported cases are distal subungual onychomycosis (DSO). In our knowledge no cases of proximal onychomycosis (PO) has been reported. For the first time we report proximal onychomycosis. This case report describes the isolation of Malassezia furfur from fingernails.
Case presentation: An Iranian 56- year- old women had been referred to mycology lab with hyperkeratosis in proximal regions of right hand nails and clinical diagnosis of onychomycosis without paronychia in May 2012. She used several medicines for her cardiac disease, mental illness, severe stress and blood glucose fluctuation diseases. Scraping and sampling from nail lesions were done, budding yeast cells with broadband connections were observed in 15% KOH wet mounts. Also, other differentiation tests, consist of staining with methylen blue, cultures and biochemical tests were done. In order to rejecting the probable etiologic role of any dermatophytic or non-dermatophytic fungi in this case, samples were collected from other parts of the body by scotch tape and scraping with scalpel blade too, but the results of direct microscopy and culture were negative. Finally, Malassezia furfur was identified as the causative agent of onychomycosis.
Conclusion: Despite failure to prove Malassezia furfur keratinolytic ability, it can be the etiologic agent of proximal onychomycosis that shows the aggressive properties of this species. Its clinical importance is the easier transmission to hospitalized patients and other people.
