Abstract
Introduction: Hand eczema is one of the most common causes of disabiliting dermatoses. Objective: Our purpose was to determine the frequency of hand eczema in out patients seen in Razi hospital (university medical center). Design: Of 3754 patients with skin problems, 206 were investigated for hand eczema and the study was carried out with regard to age, sex, occupation, exposure to chemical and physical irritants and predispositional factors. Results: The prevalence of hand eczema was 5.48%. The mean age was 30.8 years. The female: male ratio was 1.6. The highest number of patients were in the occupational group with exposure to reegents and water (we couldn't do patch test because it was not available). The most common complaint was itching (85.5%) and the fingers were the predominant affected sites. Conclusion: The major cause of hand eczema in contact dermatitis (Irritant and Allergic) and patch testing in necessary to determine the allergic agent, that can be helpful in allergic contact dermatitis (ACD) but are sometimes discouraged because of high false-positive rate and also in many instances, simultaneous exposure to irritant factors plays an essential role in the development of ACD.

Abstract
This is a report of the first serological survey of influenza C virus in Iran, performed during a one year period (March 1997-May 1998). This study was accomplished in the National Influenza Center-Division of Virology in Tehran University of Medical Scinces. 1080 samples of serum (689 samples from Tehran and 391 samples from other provinces) were assayed for the presence of antibodies against influenza C virus (C/Paris/1/67) by haemagglutination inhibition (HI) test. 43.7% of people tested in Tehran and 40.7% of people tested from other provinces had protective antibodies against influenza C virus. Distribution of seropositives in various age groups had a somewhat similar pattern as what has been reported from other countries. The results of this study indicates that the lowest level of protective antibody titer is found at childhood and the level increases with age. The protective antibody titer level off for 20-30 years old age group and decreases in older age groups. These results indicates a primary contact in childhood, reinfection in adulthood. The influenza C virus is simultaneously circulating in Iran with other types of influenza viruses (types A and B).

Background: Chronic peritoneal dialysis
is a safe method for the treatment of end-stage renal failure. Worldwide,
patients on chronic peritoneal dialysis constititute approximately 15%
of the total number of patients on dialysis. In Iran, very few people have access
to chronic peritoneal dialysis, which is targeted by the Ministry of Health. This
lack of access is primarily due to the high occurrence of mechanical
complications. Improving catheterization procedures is an important way to
extend the use of peritoneal dialysis in Iran. Thus, a prospective study was
implemented to evaluate the outcome of a new laparoscopic technique for the insertion
of peritoneal dialysis catheters under local anesthesia.
Methods: A
total of 115 catheters (two-cuff, swan-necked, coiled) were
inserted into the peritoneal cavity of 109
patients with end-stage chronic renal failure during a 16-month
period. The method of insertion was a two-port laparoscopic technique with
local anesthesia and sedation. All patients were followed for 12
to 28 months. We prospectively evaluated mechanical
and infectious complications and survival rates of the catheters.
Results: The
average age of the patients was 51.5 years (range: 15-84
years) 54.8% of these patients were female. The overall
one-year and two-year catheter survival rates using this approach were 88%
and 73%, respectively. Event-free catheter survival
was 35%. The most common infectious and mechanical
complications were peritonitis in 52
cases (45.2%) and temporary dialysate leakage in 10
cases (8.7%) respectively.
Conclusion: Laparoscopic insertion of
peritoneal dialysis catheter with local anesthesia is a safe and simple
procedure, giving reasonable rates of catheter survival and complications.

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.

Abstract
Background: In kidney transplantation decision about the proper kidney donation is different between surgeons, but simple vasculature anatomy and a kidney without abnormalities are the most important reasons of choosing a kidney. Therefore complete assessment of renal vessels of a live donor with noninvasive techniques is a necessity for nephrectomy. For delineation of the kidney vasculature anomalies and urinary system abnormalities, Multi-Detector CT seems to be excellent method for evaluation.
Methods: In this study 59 live donors were assessed with Multi-Detector CT Angiography. After injection of contrast media, we acquired images with 0.6 mm slice thickness. Processing and three dimentional reconstructions were done and the accessory arteries, early branching of main renal artery, the number of main renal vessels and the ureters were assessed. Findings were compared with the nephrectomy results.
Results: In Multi-Detector CT Angiography the prevalence of accessory renal artery was 3/4% with 98% accuracy, early branching of main renal artery was 8/4% with 100% accuracy. Multiplicity of renal veins was seen in 8/4% of donors with 98% accuracy. Duplicated ureter was not seen in any of the donors.
Conclusions: The accuracy of CT Angiography is 95% for depicting accessory renal artery and multiple renal artery and 100% for early branching. These results were comparable with findings in conventional angiography. Studies showed this method more valuable than M.R. Angiography and digital subtraction angiography. It is less invasive and can be named as the gold standard method in the diagnosis of anomalies of vessels & collecting system in live donors.

Abstract
Background: A correlation between coronary artery disease (CAD) and atherosclerosis of peripheral arteries and the determination of noninvasive indexes for its existence and extent have been sought by many researchers. Some studies report that the intima-media thickness (IMT) of peripheral arteries could play this role. This study evaluated the correlation between the IMTs of common carotid and common femoral arteries and the degree of atherosclerosis in aortic arch and to evaluate the severity of CAD in candidates of coronary artery bypass grafting (CABG).
Methods: In a cross-sectional analytic-descriptive study, The severity of CAD, the grade of atherosclerosis of the aortic arch, and the IMTs of the common carotid and common femoral arteries were determined.
Results: There was a significant weak positive correlation between the IMT of common carotid artery (ρ = 0.193, p = 0.039) and common femoral artery (ρ = 0.206, p = 0.028) with the number of involved carotid vessels the mean of these two parameters was not significantly different between the three CAD groups. There was not any significant relation between the IMTs of common carotid and common femoral arteries with the severity of atherosclerosis in the aortic arch too. There was not any significant relation between the presences of atherosclerotic plaque in the common carotid or the common femoral arteries with the severity of CAD. The severe atherosclerosis of the aortic arch was significantly higher in patients with three vessel disease.
Conclusion: According to our results, the IMTs of common carotid and/or common femoral arteries may increase with the severity of CAD however, these parameters are not a surrogate for predicting the CAD severity.

Abstract
Background: Atrial fibrillation is the most common but benign arrhythmia following cardiac surgery. Although this arrhythmia is often self-limited and vanishes in about 24 hours upon surgery a number of arrhythmias might ensue among which some might be really life-threatening. A multitude of therapeutic modalities have been proposed for the prevention of this arrhythmia and one of them is posterior pericardiotomy. This method has not been fully accepted by the peers yet and more studies are needed to prove its efficacy and benefits to the patients.
Methods: In this single-blind randomized clinical trial, done over a 2-year period from February 2009 to January 2011, the effects of posterior pericardiotomy were evaluated in 174 patients (87 the case and 87 the control groups) undergoing elective coronary artery bypass grafting (CABG). The case group underwent CABG with posterior pericardiotomy while the control group underwent CABG-only operation. The postoperative incidence of arrhythmia, especially atrial fibrillation, was assessed for a week using statistical methods.
Results: The prevalence of postoperative atrial fibrillations were fewer in the group undergoing CABG with posterior pericardiotomy compared with the CABG-only group (P<0.004).
Conclusion: Posterior pericardiotomy seems to reduce the incidence of atrial fibrillation following elective CABG therefore, its application is suggested for elective
CABGs

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: With approximately 386,000 deaths per year, esophageal cancer is the 6th most common cause of death due to cancer in the world. This cancer, like any other cancer, is the outcome of genetic alterations or environmental factors such as tobacco smoke and gastro-esophageal reflux. Tobacco smoking is a major etiologic factor for esophageal squamous cell carcinoma in western countries, and it increases the risk by approximately 3 to 5 folds. Chronic gastro-esophageal reflux usually leads to the replacement of squamous mucosa by intestinal-type Barrett’s metaplastic mucosa which is considered the most important factor causing esophageal adenocarcinoma. In contrast to esophageal adenocarcinoma, different risk factors and mechanisms, such as mutations in oncogenes and tumor suppressor genes, play an important role in causing esophageal squamous cell carcinoma. Molecular studies on esophageal cancers have revealed frequent genetic abnormalities in esophageal squamous cell carcinoma and adenocarcinoma, including altered expression of p53, p16, cyclin D1, EGFR, E-cadherin, COX-2, iNOS, RARs, Rb, hTERT, p21, APC, c-MYC, VEGF, TGT-α and NF-κB. Many studies have focused on the role of different polymorphisms such as aldehyde dehydrogenase 2 and alcohol dehydrogenase 2 in causing esophageal cancer. Different agents including bestatin, curcumin, black raspberries, 5-lipoxygenase (LOX) and COX-2 inhibitors have been found to play a role in inhibiting esophageal carcinogenesis. Different gene therapy approaches including p53 and p21WAF1 replacement gene therapies and therapy by suicide genes have also been experimented. Moreover, efforts have been made to use nanotechnology and aptamer technology in this regard.

Background: Abnormal iron homeostasis such as iron deficiency or iron excess is associated
with the pathogenesis of many chronic diseases including diabetes and
cardiovascular disease (CVD). Iron may stimulate the
progression of atherosclerosis by increasing the oxidative stress. Changes in
carotid intima-media thickness (CIMT) have been
validated as a vascular indicator of atherosclerosis progression. The purpose
of this study was to apply CIMT to investigate the
association between iron status and the initial stages of atherosclerosis.
Methods: 140 healthy premenopausal women aged 18
to 50 years who had no
chronic or acute disease were selected randomly from one of the Tabriz
university sub specialized clinics. Blood samples were taken to assay iron
status parameters. CIMT was measured
noninvasively by ultrasonography. Based on CIMT
results, the subjects were classified as "healthy" (CIMT
≤0.8 mm) or "at risk" (CIMT >0.8 mm).
Student's t-test was used to determine the mean differences between the two
groups.
Results: The mean±SD age of the participants was 32.76±8.1 years.
The mean iron, ferritin, hematocrit and mean corpuscular volume (MCV)
were significantly higher and the total iron binding capacity (TIBC)
was lower (P<0.05) among the "at risk"
group. However, there was no significant differences in red blood cell count or
hemoglobin levels between the two groups (P>0.05).
Conclusion: Results
of this study showed a relative correlation between iron status parameters and
CIMT as the initial indicator of CVD. Regarding
the contradictions found
in the literature, more research is needed to clarify the situation.

Background: Distinguishing the origin of ventricular tachycardia (VT) by electrocardiogram (ECG) which is performed in all
patients, helps to diagnose the cause of VT before trying invasive procedures. The aim of this study was to
compare the ECG findings in patients with VT originating from Right or Left Ventricular Outflow Tracts (RVOT or LVOT).
Methods : Fifty nine patients with VT originating from LVOT or RVOT were selected for this cross-sectional study. The patients were
recruited while they were attending Shahid Rajaei Hospital in Tehran, Iran in 2009-2010 for catheter ablation.
The participants were evaluated for the prevalence of LVOT and RVOT and were compared for the success
rate of radiofrequency catheter ablation.
Results : Out of 59 patients, 44.1% were male and 55.9% were female. The mean age of the participants was 41.67 (SD=13.76) years. QRS transition and notch in ECGs were significantly different
(respectively, P=0.027 and P=0.007) between patients with LVOT and RVOT. R-to-QRS duration in precordial leads was significantly longer in patients
with LVOT than
those with RVOT [0.81 (SD=0.06) ms vs. 0.69 (SD=0.16), P=0.015]. Successful ablation was performed in 73.2% of patients with RVOT versus 93.3% of those with LVOT, but despite a higher rate the
differences were not statistically significant (P=0.215).
Conclusion: In this study, RF catheter ablation was
successful like other studies on patients with ventricular tachycardia and RVOT VT and LVOT VT had significant differences
in notch, QRS transition and R-to-QRS duration in precordial leads which are important in differentiating
between the two conditions.

Abstract
Background: Although sexual dysfunction is a common problem in patients with obsessive-compulsive disorder (OCD), there are sparse clinical research on the study of the correlation between OCD subtypes and different phases of sexual response cycle. This study was undertaken to assess sexual function and its different phases in a group of Iranian patients with OCD. Methods: This was a descriptive cross-sectional study. The subjects consisted of 56 married OCD patients (36 female, 20 male) who suffered from OCD according to a psychiatric interview and DSM-IV questionnaire based on structured clinical interview for DSM (SCID). Patients were between 18 to 50 year age that had been referred to the outpatient clinic of Roozbeh Psychiatric Hospital and three private psychiatric clinics in Tehran (from September 2011 to February 2013). Five Questionnaires were used in this study: Iranian validated form of Female Sexual Function Index (FSFI), International Index of Erectile Function (IIEF), Maudsley Obsessional Compulsive Inventory (MOCI), Obsessive Compulsive Inventory-Revised (OCI-R) and a questionnaire which has provided demographic data and other relevant information regarding sexual function and OCD. Results: The prevalence of sexual dysfunction among female was 80.6% and the frequency of disorders in different subscales of FSFI including sexual desire, sexual arousal, lubrication, orgasm, satisfaction and sexual pain were 50%, 58.3%, 36.1%, 44.4%, 41.7% and 52.8% respectively. Sexual disorder is reported in 25% of male OCD patients which subscales' evaluation of IIEF shows low sexual desire in 10%, erectile disorder in 20%, orgasmic disorder in 25%, sexual dissatisfaction in 40% and 50% decreased in the total sore of IIEF. Moreover, the correlation coefficients between the total score of OCI-R with erectile and satisfaction subscales of IIEF were statistically significant. The score of washing subscale in OCI-R and sexual satisfaction was significantly correlated. Conclusion: High prevalence of sexual dysfunction in OCD women and significant correlation between male sexual dysfunction and OCD (r= -481.0 between total score of OCI-R with erectile dysfunction and r= -458.0 between total score of OCI-R and sexual satisfaction) could confirm a relation between OCD and sexual disorders. So, evaluation of sexual function in all patients with OCD is recommended.

Abstract
Background: Even after surgery, as the most effective treatment for colorectal cancer, about 30-40% of cases are recurring. Since growth inhibition is an important strategy in cancer treatment, many attempts are in the program to find new agents, so in this study, the cytotoxic and antimicrobial effects of Lactobacillus sakei on colon cancer cell line (HT-29) and some pathogenic microorganisms have been evaluated. Lactobacillus sakei is a probiotic that, when consumed affects the intestinal flora, causes beneficial effects on host health. Probiotics due to their anti-cancer effects, modulation of the differentiation process in tumor cells, changes in tumor gene expression and lack of immunological responses have attracted a lot of attention as a new and effective treatment for colorectal adenocarcinoma.
|
Methods: In the present study, which was conducted experimentally from May to September 2018 in bacteriology and Cellular and Developmental Research Centers of Islamic Azad University, Shahrekord branch, the antimicrobial activity of supernatant of Lactobacillus sakei was assessed by Well Diffusion Agar (WDA) method against some pathogenic bacteria. HT-29 Colorectal adenocarcinoma cancer cells were cultured in DMEM medium with 10% bovine serum. The cells were treated in 5, 15, 10 and 20 mg/ml concentrations of sakei metabolites and incubated at 24, 48 and 72 hours. Cell growth was analyzed by celltiter 96® aqueous one solution cell proliferation assay kit to the manufacturer's protocol in all three incubation times.
Results: The results of this study indicate that sakei was able to produce antimicrobial metabolites against pathogenic bacteria. Besides, the results of the celltiter 96® aqueous one solution cell proliferation assay showed that the bioavailability of HT-29 cell lines decreased at all concentrations of sakei metabolites in a dose and time-dependent manner.
Conclusion: Since lactic acid probiotic bacteria can alter the metabolic activities of the intestinal microflora, attach to carcinogens and destroy them, prevent carcinogenesis such as ammonia and secondary bile acids, producing anti-cancer substances and creating an acidic state to inhibit the growth and proliferation of carcinogenic bacteria, It seems that there is a good research field for the use of bioactive compounds produced by Lactobacillus sakei in the control of bacterial pathogens and treatment of human colorectal adenocarcinoma (HT-29).

Abstract
Background: Despite years of continuous research, maternal mortality due to preeclampsia is still a serious threat. Researchers believe that preeclampsia is a multifactorial disease and proposed many risk factors including immunological factors for it. Given the description of preeclampsia as an excessive response of the immune system, the relationship between preeclampsia and immunological changes is of particular importance. Genetic polymorphisms are considered to be one of the causes of immunological defects. Due to the role of immunologic and inflammatory factors in the etiology of preeclampsia, in the present study, the association of rs1028181-513T/C polymorphism of interleukin 19 gene with preeclampsia in the patient and control groups who were referred to Valiasr hospital in Kazerun, was compared.
Methods: The present case-control study was conducted at Islamic Azad University of Kazerun from December 2016 to May 2017. 150 preeclampsia patients and 150 healthy pregnant women who were referred to Valiasr hospital in Kazerun, were enrolled. Genotypes of participants for the -513T/C (rs1028181) variant were determined by the Tetra Primer ARMS-PCR method. SPSS software and Chi-square statistical test were used for data analysis.
|
Results: In the position of the -513T/C (rs1028181) polymorphism, a significant difference in frequency of all genotypes (CC, CT and TT) (P=0.001) and both alleles (C and T) (P=0.002) between preeclampsia pregnant women and healthy pregnant women was observed. There was no significant relationship between the other parameters of the study with the mentioned polymorphism in the patient and control groups.
Conclusion: Due to the significant relationship between (rs1028181) -513T/C polymorphism and the occurrence of preeclampsia, which emphasizes the role of genetic predisposition in the development of preeclampsia disease, the presence of this polymorphism can be considered as a predictor of preeclampsia and concluded that polymorphic genetic markers are good predictive strategies for early detection of preeclampsia before the twentieth week of pregnancy.

Abstract
Background: Multiple sclerosis (MS), as an inflammatory autoimmune disease and chronic degenerative central nervous system degeneration, often occurs in early adulthood. One of the common and debilitating symptoms of this disease is fatigue, which can affect up to 80% of patients with MS. This study aimed to evaluate the effectiveness of magnetic field therapy on fatigue in patients with MS.
Methods: Present study is a single-blind randomized clinical trial (RCT) that Was conducted on patients with multiple sclerosis from March 2019 to September 2021. In this study, 46 patients who met our inclusion criteria were divided into two groups randomly: magnetotherapy intervention and control group. The intervention was performed in the form of a pulsed magnetic field with a frequency of 15 Hz and an intensity of 4.5 Millie Tesla. In order to blind patients, they were unaware of the intervention or control group, and the technician in charge of the treatment and the statistician knew about it. Data were then collected and recorded using the Fatigue Severity Scale, the Patient Health Questionnaire, and the Epworth Sleepiness Scale Questionnaire.
Results: Of the 46 patients studied, 22 (48%) were male and the rest of them were female [24 cases (52%)]. The mean age of men and women was 34.4±7.3 and 33.5±1.7 years, respectively. Among the intervention and control groups, 8 people took amantadine equally in each group. In the magneto-therapy intervention group, the mean severity of fatigue reduced from 4.91±0.86 to 4.27±1.10, which was significant (p=0.024). In our control group, the mean intensity of fatigue reduced from 4.83±0.83 to 4.37±0.81, which was significant statistically (p=0.028). Although, the difference between the response of the two groups to treatment was not significant (p=0.382).
Conclusion: Due to the lack of significant differences in the reduction of fatigue severity, this treatment is not recommended for the treatment and management of fatigue in patients with MS.

Abstract
Background: Considering the frequency of MRSA strains in hospitals and medical centers as well as in different communities, it seems necessary and important to observe the use of appropriate drugs in order to reduce antibiotic resistance and reduce the economic costs of treatment. This study aimed to investigate the antibiotic resistance pattern of MRSA isolated from blood and wound samples of patients. The study patients were hospitalized in different departments in a number of Tehran University of Medical Sciences hospitals.
Methods: In this descriptive cross-sectional study from September 2021 to February 2022, the blood and wound samples of the patients were collected and referred to laboratory. Staphylococcus aureus had identified by phenotypic and biotypic tests. MRSA isolates were screened by showing resistance to Cefoxitin by disc diffusion method and finally confirmed by examining the mecA gene by PCR. The microbial resistance pattern of MRSA was also measured by disk diffusion method and resistance to Vancomycin was confirmed by E.test.
|
Results: 41 isolates from 87 Staphylococcus aureus samples were confirmed as MRSA by present the mecA gene. The mecA gene was detected in all MRSA by PCR method. The antibiotic resistance pattern showed the highest sensitivity to Vancomycin and Linezolid with 100% sensitivity and the highest resistance to three antibiotics Erythromycin, Ceftriaxone and Cloxacillin with 97.57%by disk diffusion method. The most MRSA strains were isolated from the ICU department with 13 cases and the least MRSA strains were isolated from the two NICU and pediatric departments with one case.The majority of the population infected with MRSA belonged to the age group of 40-65 years.
Conclusion: The prevalence of microbial resistance with high dispersion was obtained among MRSA strains isolated from clinical samples; which indicates a significant increase in resistant strains and requires a quick and timely diagnosis to prescribe the appropriate antibiotic.

Abstract
Skin metastases from breast cancer usually occur in more advanced stages of the disease, but can sometimes be the first clinical manifestation of breast cancer or the first evidence of a previous tumor recurrence. These demonstrations significantly reduce survival. Skin metastases from breast cancer have different manifestations. The most common manifestations are nodules. These nodules are soft, round or oval, mobile, firm, and elastic in texture and can be single or multiple, often flesh-colored, but can also be brown, bluish black, and pink to reddish brown. In the absence of a previous history of cancer, it can be difficult to diagnose the early location of metastatic cancers. However, metastases usually show histopathological similarities to the primary tumor. Soft tissue breast metastases usually have a better prognosis than breast or bone cancer metastases. Also, skin metastases from breast cancer do not necessarily have a poor prognosis as skin metastases from other malignancies. The relative risk of death from skin metastases to other malignancies is more than four times higher than skin metastases from breast cancer. Differential diagnosis includes cutaneous lymphoma, intracranial leukocyte infiltration, and cutaneous metastasis. Metastatic skin lesions are often mistaken for benign lesions. Recognizing them quickly is important to prevent long-term anti-inflammatory treatment that delays proper diagnosis. Therefore, to rule out metastasis, abnormal or nodular lesions should be considered for biopsy in patients with a history of systemic malignancy or suspected malignancy. Cutaneous metastases are usually a sign of widespread disease and may not be treatable in most cases. Treatment options include systemic and/or topical treatments. Extensive skin metastases require systemic treatment. For thicker skin metastases, radiation therapy, surgical or electrochemical resection is indicated as monotherapy or in combination. Oxygen in combination with topical 5% methotrexate (OFAMTX, 5% methotrexate in a carrier solution) is a recently described method that facilitates drug penetration into the epidermis. In the absence of visceral or lymph node metastases, OFAMTX is useful as a local skin treatment. This treatment is an effective and tolerable method for superficial skin metastases. Using local treatment in combination with systemic agents increases the overall effectiveness of treatment on skin metastases.

Abstract
Background: Today, Methicillin-Resistant Staphylococcus Aureus (MRSA) has become one of the public health concerns due to its resistance to antimicrobial drugs, and this problem makes treating patients with infections caused by this bacterium difficult. Infections caused by methicillin-resistant Staphylococcus aureus (MRSA) strains are pervasive in both community and hospital settings, primarily attributable to Staphylococcus aureus' capacity to colonize areas like the nose or skin. In this study, with the aim of comparing phenotypic (disc diffusion method) and genotypic (PCR) methods, to detect methicillin-resistant Staphylococcus aureus isolated from patients of hospitals under supervision of Tehran university of medical sciences, and also detection of nor A, that is the one of the most important genes in efflux pump cluster genes.
Methods: The present research was a cross- sectional study that was conducted from February 2022 to September 2023. In this research, 43 isolated strains of Staphylococcus aureus from wound discharge and blood samples, were collected from different departments of Tehran hospitals and had submitted to the research laboratory of the school of allied medical sciences in Tehran university of medical sciences. After identifying the strains, the resistance of the isolates to 14 types of antibiotics was checked by disk diffusion method.
Results: Staphylococcus aureus diagnostic tests including gram staining on colonies, catalase, coagulase, DNase tests were performed and it was found that all strains were Staphylococcus aureus. In the next step, all samples were resistant to Cloxacillin by disc diffusion method, and the presence of mec A gene in them was confirmed by PCR method, thus the presence of MRSA strains was confirmed from the genotypic point of view. Of the 43 Staphylococcus aureus strains, 26 samples were identified as having the nor A gene by PCR and electrophoresis.
Conclusion: The results of the present research have shown that the prevalence of Staphylococcus aureus bacteria in hospital samples is significant and resistance to methicillin and ciprofloxacin has increased in the strains of this bacteria. |
