Abstract
Background: Necrotizing soft tissue infections are one of the most dreaded infections in human and result in a very high rate of mortality. The treatment of these infections must be very aggressive and consists of radical debridement of all necrotic tissue accompanied by appropriate antibiotics.
Materials and Methods: This study was undertaken to assess the mortality rate, the time from diagnosis to cure, and some of the parameters which may affect mortality in our patients. In this descriptive, retrospective study first files from patients attended by necrotizing soft tissue infections including Fournier's gangrene or disease, gas gangrene, hemolytic streptococcal infections, myonecrosis, necrotizing fascitis and related subjects in Sina and Amir-Alam hospitals from 1989 to 1999 were studied. Data were extracted and analyzed by SPSS.
Results: The total number of cases was 36. The median age was 47.69 years. Seven of the patients were female. The median time from onset to cure was 10 days. The most common site affected was the perineum and the most common etiology was perianal abscess. Diabetes mellitus was the underlying disease mostly observed. Half of the patients had received inappropriate treatments. In this group mortality was higher.
Conclusion: It is crucial that general practitioners be acquainted with the diagnosis of necrotizing soft tissue infections so that patients are referred immediately to surgical centers. In our referral center the mortality was acceptable but it can be lowered further. The sex, sites of infection, underlying disease and etiologies in our patients were similar to patient in other countries except for alcoholism. It appears that data in foreign texts can be attributed to Iranian patients.

Abstract
Background and Aim: Sudden Sensorineural Hearing Loss (SSNHL) is an emergency situation, and is one of the most controversial subjects in domain of otolaryngology. In this article, we have analyzed some Epidemiologic Characteristics, clinical features, audiological Characteristics, and other findings in routine serological tests and MRI of 48 cases with SSNHL ,who came or were referred to us in the past 2 years. Study design: Cross sectional.
Materials and Methods: In 48 patients with chief complaint of SSNHL, from June 2003 to Feb. 2005, who were admitted in clinic of otolaryngology- in Kashani Hospital -Isfahan- Iran, physical examination and history taking, audiological evaluation, MRI,and serological tests were performed in a similar way , and data were analyzed by SPSS software.
Results: From 48 cases(M:28 ,F:20) with mean age of 40.9(+/-15.9) years, left ear was involved in 26 cases (54.1%) ,and right ear in 19 cases (39.5%) ,and in 3 cases (6.3%),both sides were involved. The severity of hearing loss was “subjectively” HIGH in 78% of patients, and the mean threshold of hearing had been calculated as 69 dB. The most common pattern in pure tone audiometry curves ,was ‘flat pattern’(75%) ,and then ,’down sloping pattern’(16%).The most adjunctive clinical symptom was “tinnitus”(in 78.7%), and 40% of patients had “true vertigo”. 44.4% of our patients had some evidences of upper respiratory tract infections (URIs) during recent 2 weeks. Positive family history, smoking, alcohol intake ,oral contraceptive and ototoxic drugs consumption were uncommon. 24% of cases (11 of 39) had increased ESR, and 100% of 39 patients had negative VDRL. Diabetes mellitus was the most common underlying disease (in 6 cases).From 20 patients ,who were succeeded to perform brain and ear MRI, 2 cases had tumor in internal auditory canal and cerebellopontine angle.
Conclusion: SSNHL has some limitations in being studied histopathologically or in the form of clinical trials, and in nearly all of its aspects there are some mysteries to be cleared. Our ‘Iranian’ patients demonstrated some special characteristics.

Abstract
Background: Respiratory virus infections represent a major public health problem because of their worldwide occurrence, ease of spread in the community and considerable morbidity and mortality. They are one of the most common reasons for hospitalization of children under the age of six. In some cases, infection with two different viruses increase the severity of disease which lead to the hospitalization.
Case presentation: Among 202 samples related to children under the age of six with respiratory infections, two dual infections of Adenovirus with other respiratory viruses with PCR test were detected.
Conclusion: Mixed respiratory viral infections are sometimes associated with severe disease and recognition of coinfection is important. Dual infections of Adenovirus with respiratory syncytial virus (RSV) and Swine origin influenza A (H1N1) virus were demonstrated. The evidence showed that the co-infection of Adenovirus with swine origin influenza A (H1N1), has increased the severity of disease which lead to the hospitalization.

Abstract
Background: Common Variable Immunodeficiency (CVID) is a primary immunodeficiency disease, characterized by hypogammaglobulinemia and heterogeneous clinical manifestations. This study was performed to evaluate the clinical and immunological features of pediatric patients with CVID.
Methods: We reviewed the records of 69 children diagnosed under age of 16 years with CVID (35 males and 34 females).
Results: By the year 2008, 15 patients (21%) had died. The total follow-up period was 333 patient-years. The mean diagnostic time between onset and diagnosis in our patient group was 4.40 years. The overall rate of consanguineous marriages was 58%. 10 patients had a positive family history of immunodeficiency. At the time of diagnosis, the mean levels of serum immunoglobulin G (IgG), IgM, and IgA levels were 286.86, 39.92, and 18.39 mg/dl, respectively which were below the normal levels for age. All of the patients presented with infectious diseases at the time of onset, the most common of which were pneumonia, diarrhea and sinusitis. Acute and recurrent infections were also found in almost all of the patients, particularly involving respiratory and gastrointestinal systems. The most common infections during follow-up period were pneumonia (31.9%), acute diarrhea (18.8%), acute sinusitis (18.8%), and otitis media (14.5%). Post-diagnosis survival was estimated to be 79% during the first five years. The survival rate was not shown to be influenced by delayed diagnosis, serum levels of IgG and B-lymphocyte count at the time of diagnosis.
Conclusions: Any child with a history of recurrent infections, decreased levels of serum immunoglobulin isotypes and consanguineous parents should be considered as a CVID patient.

MicrosoftInternetExplorer4 Background: Staphylococcus aureus infection pervasively occurs in communities and
hospitals and observing related guidelines is essential in preventing development
of antibiotic resistance in Hospitals. In this study we tried to determine the
prevalence of Methicillin and vancomycine resistant staphylococcus aureus (MRSA
& VRSA) and find the most suitable diagnostic tool and
treatment in affected patients.
Methods: This study was performed on hospitalized patients in Sina Hospital in Tehran,
Iran during 2009-2010. Eighty-five staphylococcus
aureus samples were evaluated for resistance to oxacillin and vancomycine
by both disc diffusion and E-test methods.
Results: The study population included 46 male and 39
female patients. The mean age of the participants was 51.46±19.21
years. The MRSA frequency was 50%.
67 (78.8%) patients had hospital-acquired
staphylococcus infection. The rate of hospital-acquired MRSA
was 93%. Length of hospital stay, undergoing invasive
methods, history of antibiotic use three months prior to hospitalization and its
kind were recognized as MRSA risk factors. There
were no reports of VRSA except one case of vancomycine-intermediate
S. aureus (VISA). The results of disk effusion and E-test
methods were consistent.
Conclusion: Considering
the prevalence of methicillin resistance in hospital-acquired infections, it seems
that oxacillin should not be used as the first-line option for empiric therapy
against S. aureus till
antibiogram results are available. Disc diffusion can also be reliably used
instead of the more expensive E-test.

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: Renal transplantation is the treatment of choice in patients with end-stage renal disease. Urinary tract infection (UTI) is one of the most common complications after renal transplantation and it has serious consequences. The aim of this study was assessing UTIs in renal transplanted patients and evaluation of risk factors associated with post-transplant UTI.
Methods: In this prospective study, 173 patients (48 hospitalized patients and 125 outpatients) were enrolled in this study. These renal transplant recipients evaluated for bacterial urinary tract infection in urology research center at Sina Hospital. After collecting urine samples from symptomatic and asymptomatic patients, urinalysis and colony count were performed. Identification of bacteria was performed by routine microbiological tests in the Department of Pathobiology, School of Public Health, Tehran, Iran, in 2011.
Results: UTI was observed in 47 patients and the most prevalent microorganism was Escherichia coli (E.coli) 18(38.2%). Nearly 71% of UTI cases were diagnosed during the first three months post transplantation. Risk factors for post transplant UTI were female gender, age, length of hospitalization and diabetes mellitus. Female patients were more susceptible than males (OR=0.50 and P=0.047) to infection. There were no significant difference between diabetes mellitus and UTI. Most of the isolated bacteria were susceptible to imipenem and resistant to tetracycline and trimethoprim- sulfamethoxazole.
Conclusion: Our study confirmed that bacterial infections remain as the most common infectious complication in the early post-transplant period, and antibiogram rather than empirical treatment is needed to find the best effective antibiotics. Moreover, risk factors such as female gender, increased age and length of hospitalization are predisposing factors to increased urinary tract infection in renal transplantation.

Abstract
Background: Severity of respiratory infection in children is depended on various fac-tors such as causative organism and the host immunologic response to the organism. Vitamins and micronutrients play an important role in this response with supporting the immune system and therefore, the response to infections. Nutritional deprivations in children, especially vitamins and micronutrients such as zinc, vitamin A and vitamin D are very common in middle east and other countries in Asia, which is due to inappro-priate diet and nutrient loss in recurrent infections. This study aimed to evaluate the se-rum levels of vitamins A, D and zinc in hospitalized children aged six months to five years. Methods: This analytic cross-sectional study was performed in 65 children aged six months to five years who were hospitalized in pediatric and surgical wards of Rasul Akram Hospital and Bahrami Hospital in Tehran. All of samples were evaluated ac-cording to WHO cri-teria for acute respiratory infection, and underwent measurement of serum vitamin A, vitamin D and zinc levels by using Atomic, Elisa and spectropho-tometer methods. Results: Serum levels of vitamins A in patients with acute respiratory infection was 0.27±0.16 µg/ml and in children without infection was 0.41±0.2 µg/ml, that different wasn’t statistically significant (P=0.4). Serum levels of vitamins D in patients with acute respiratory infection was 35.37±34.68 ng/ml and in children without infection was 45.78±21.05 ng/ml, that different wasn’t statistically significant (P=0.1). Serum levels of zinc in patients with acute respiratory infection was 87.93±23.34 µg/dl and in chil-dren without infection was 106.95±23.70 µg/dl, the difference was statistically signifi-cant (P=0.002). Conclusion: According to finding in this trial, there is a correlation between lower levels of zinc in serum, and chance of respiratory tract infection in children. Future larger studies could provide the correlation between serum levels of vitamins A & D and chance of respiratory tract infection.

Abstract
Background: Hyperemesis gravidarum (HG) starts between four and seven weeks after the first day of the last period, and ends at twenty weeks of pregnancy. The etiology of HG, is unknown. Recent studies worldwide show the Helicobacter pylori (H. pylori) infection as a possible cause of the severe nausea and vomiting in pregnancy, recent studies showed H. pylori to have a role in occurrence of it during pregnancy. The current study assessed the immunoglobulin G (IgG) and immunoglobulin M (IgM) titer to H. pylori in pregnant women with HG. Methods: This is a case-control study of the pregnant patients of a gynecologist's office in the Marvdasht city from April to September 2013. One hundred and twenty three patients were randomly chosen based on their conditions and were divided into two groups (case n1= sixty three and control n0= sixty). The IgG and IgM titers against H. pylori were measured by ELISA method. Data analysis was performed using Chi-square test, Mann-Whitney U-test, and T-test in SPSS software, version 20 (SPSS, Inc., Chicago, IL, USA). The significant level of the test was considered (P= 0.05). Results: Totally, 123 pregnant women were evaluated 63 women with hypermesis gravidarum and 60 without HG. Forty nine women out of 63 in HG group and 48 women in the control group were IgG positive for H. pylori. Also, mean serum level of IgG was 51.6 in the HG group (P= 0.685). Twelve women out of 63 in HG group and 20 women in the control group were IgM positive for HP. Also, mean serum level of IgM was 27.7 in the HG group (P= 0.675) Except for the mother's blood type, there were no other statistically significant differences found between the two types of antibodies against H. pylori. Conclusion: There is no relationship between helicobacter pylori and hyperemesis gravidarum in pregnant woman. Considering the high prevalence of H. pylori infection in our country, there is a need for studies with more samples and more diagnostic methods.

Abstract
Background: Antimicrobial resistance is a growing problem in many bacterial pathogens and is of particular concern for hospital-acquired nosocomial infections. Klebsiella pneumonia is an important cause of nosocomial infections has rapidly become the most common extended spectrum beta-lactamases (ESBLs) producing organism. ESBL are defined as the enzymes capable of hydrolyzing oxyimino-cephalosporins. The aim of this study was to compare phenotypic detection of ESBL using two phenotypically method among the clinical isolates of Klebsiella pneumoniae. Methods: In this cross-sectional study a total of 144 isolates from clinical samples Urine, sputum, wound, blood, throat and body fluids isolated and identified as K. pneumoniae in a teaching hospitals in Shiraz within a six months period from December 2012 to May 2013. Antibacterial susceptibility test performed to 14 antibiotics by the disk diffusion method according to CLSI guideline and then isolates that were resistant to at least one of the beta-lactam antibiotics evaluated for the production of beta-lactamase enzymes by using E-test ESBL and combined disk method. Results: Totally 38 (26.3%) isolates produced ESBLs. All ESBL producing isolates were susceptible to imipenem and meropenem and resistant to aztreonam. The highest antibiotic resistance was observed for amoxicilin (100%) and the lowest antibiotic resistance was observed for meropenem (9.7%). The number of 38 (100%) isolates were identified as ESBL producer by using E-test ESBL ceftazidime. It was while using the combined disks ceftazidime/clavulanic acid, cefotaxime/clavulanic acid and cefpodoxime/clavulanic acid, respectively 35 (92.1%), 34 (89.4%) and 31 (81.5%) of isolates identified as beta-lactamase producing isolates. Conclusion: Considering the high prevalence of bacteria producing ESBL, screening for infections caused by ESBL-producing isolates may be lead to the most effective antibiotics therapies.

Abstract
Background: Bacterial sepsis is a main cause of mortality and morbidity especially in preterm newborns. The aim of this study was to search the bacterial etiologies of neonatal sepsis in NICU admitted preterm neonates.
Methods: A descriptive cross-sectional study had done in NICU of Ali Asghar Hospital, Tehran, Iran from March 2007 to March 2009. Seventy septicemic preterm newborns (<37 weeks) were studied. At admission day, for blood culture, 1-2 ml of venous blood was drawn after swabbing the venipuncture site with alcohol. After centrifugation of blood samples, deposits were cultured on sheep blood agar and incubated in a candle jar at 37 °C for 48 h and followed by subcultured. Isolates were identified using standard techniques (Nima pouyesh, Iran). Type of isolated bacterial organisms determined. Its correlation with gestational age, birth weight, premature rupture of membranes (PROM) and other variables determined we used the nonparametric two independent sample test, Mann-Whitney U test. Chi-square values (CI 95%, P< 0.05) were calculated for all categorical variables. P-value less than 0.05 considered statistically significant.
Results: Of 70 studied septicemic preterm cases, 17 (10.6%) cases had positive blood culture. Overall gram-negative organisms were more frequent than gram-positive organisms, Klebsiella (K.) pneumoniae, Escherichia (E.) coli and Staphylococcus (S.) aureus organisms were the 3 common causes of bacterial sepsis in studied cases. Early onset sepsis produced by K. pneumonia (40%), E. coli (20%) and S. aureus (20%). K. pneumonia, E. coli, S. aureus had equal incidence in late onset sepsis (26.8%). K. pneumonia was more frequent in early onset sepsis (P= 0.05), and in low birth weight (< 1500 g) neonates (P= 0.005, and PROM (P= 0.05).
|
Conclusion: Three causes for sepsis in premature newborns were determined: K. pneumonia, E. coli and S. aureus, it is so important for initial antibiotic treatment in admission day. Low birth weight, prematurity, and, PROM were the common risk factors for sepsis in cases. By preventing of low birth weight, low gestational age, and PROM the risk of sepsis could be decreased. We recommend empiric antibiotic in septic preterm newborns which can cover: K. pneumonia, E. coli and S. aureus in our center. |

Abstract
Background: Urinary tract infection is a common infectious disease in children and associated with the risk for renal scarring and long-term complications, usually consists of pyelonephritis and may cause complications such as scars in kidney, hypertension and renal failure. Some studies demonstrated association between urinary tract infection and electrolyte disturbances such as hyponatremia. The present study has been designed for assessment of association between urinary tract infection and hyponatremia in children.
Methods: This is a descriptive, cross-sectional study has been conducted on 120 children have referred to the Golestan Hospital, Ahvaz Jundishapur University of Medical Science from 21 March 2011 until 20 March 2013. A total of 120 children who were aged 6 months to 12 years and had febrile urinary tract infection. The study population and were classified into two group of sixty children: hyponatremic and nonhyponatremic. We compared the laboratory findings in two groups with each other. The data included serum sodiom level, white blood cell (WBC) count, erythrocyte sedimentation rate (ESR), C-reactive protein (CRP) and ddimercaptosuccinic acid (DMSA) scan results collected from children with febrile urinary tract infections admitted in pediatric ward. Data analysis was performed using descriptive statistics, chi-square and independent T-test with SPSS software, ver. 20 (IBM, Armonk, NY, USA).
|
Results: In this study, 120 patients, 104 females (86.7%) and 16 males (13.3%) aged six months to 12 years were evaluated. All the patients were studied in terms of positive DMSA Scan. In the first group (hyponatremic) 31, and the second group (without hyponatremia) 13 patients were identified. There was a significant association between hyponatremia and WBC count, ESR, CRP, duration of fever and abnormal DMSA scan. Conclusion: We conclude that there is significant association between hyponatremia and severity of urinary tract infection in children. |

Abstract
Background: Urinary tract infections are very common in patients with high blood pressure. Hypertensive patients experience an average of three times of urinary tract infection per year. Blood pressure control is very important for preventing complications and also for identifying high-risk groups. Since, there is no national related study in this regard, the present study was conducted to investigate the effect of chronic hypertension on the incidence and recurrence of urinary tract infections.
Methods: In this case-control study, the required data were collected from outpatient cases referring to Taleghani Hospital and Sina Hospital related to Tabriz University of Medical Sciences in Tabriz city, Iran. Data needed for the control group included patients accompanying patients who had no symptoms of urinary tract infection and with no history of blood pressure.

Data needed for the control group included patients accompanying patients who had no symptoms of urinary tract infection and with no history of blood pressure.
| Results: 60 patients with urinary tract infections were examined: 57 (47.5%) of the subjects were men and 63 (52.5%) women. There was a significant relationship between the rate of red blood cell deposition in the first hour and systolic blood pressure. There was no significant correlation between the numerical value of white blood cell count and systolic or diastolic blood pressure in the studied patients. |
Conclusion: According to the results of the present study, there was a significant difference in systolic blood pressure in patients ESR 1 hour (red blood cell deposition rate in the first hour) with hypertension in case and control groups. There was a significant correlation between the ESR of the first hour and systolic blood pressure in the study, so that with an increase in ESR 1h, the systolic blood pressure increased in the examined patients, however, no significant correlation was found between ESR 1hour and diastolic blood pressure. Also, there was no meaningful correlation between the numerical value of white blood cell count and systolic or diastolic blood pressure in the studied patients. There was no significant correlation between systolic and diastolic blood pressure and age.

Abstract
Background: In the last 10 years, co-infection of human immunodeficiency virus/human T-cell leukemia virus-1 (HIV/HTLV-1) has emerged as a worldwide health problem. These viruses has the same route to infect human but different effects on CD4 positive T-cells. There was controversial results about the influence of co-infection HIV/HTLV-1 pathogenesis. This study compared clinical course and laboratory findings in HIV/HTLV-1 co-infection with HIV mono infection.
Methods: This historical cohort study carried in Mashhad Consultation Center of Infective and Behavior Diseases, Mashhad, Iran, from April 2013 to march 2017. Persons who referred evaluated by the enzyme-linked immunosorbent assay (ELISA), then patients with positive ELISA test rechecked by ELISA and Western blot. Platelet count, WBC count, neutrophils count, positive CD4 T-cells, staging and disease severity evaluated at diagnosis, in starting and after of antiretroviral therapy in mono and co-infected patients. Demographic characteristics, including age, educational level, occupational state, marriage situation, past medical history and high-risk behaviors were extracted from the files.
Results: Of 64 patients enrolled in this study, 61 persons were male. Of 64 participants patients, 42 persons were infected with HIV (35 persons of them were positive for hepatitis C virus), other 22 positive HIV cases, were co infected by HTLV-1 too (18 persons were positive for hepatitis C virus (HCV). Co infected patients had more history of high-risk situations specially intravenous drug abuse. The most common opportunistic infections was cryptogenic tuberculosis (TB), candidiasis and military TB. Opportunistic infections and lab findings (except for CD4 positive T-cell) were the same in both group. Clinical severity and disease staging did not differ significantly between two groups. Death was more common in co-infected group.
Conclusion: Clinical course in human T-cell leukemia virus-1 (HTLV-1) co-infection has not obvious differences with previously HIV patients compare with only HIV infected patients. In co-infection with the onset of treatment the increase in the level of CD4 positive cells was higher than that HIV infection.

Abstract
Background: With increasing immunocompromised patients, fungal infections especially lung infection, have also increased. In this study, fungal contamination of the respiratory system in immunocompromised patients was evaluated.
Methods: This descriptive cross-sectional study was conducted in immunocompromised patients suspicious of pulmonary infections referring to specialized lung clinic of Amir-Al-Momenin University Hospital in Arak City, Iran, from April 2017 to June 2018. Of these 64 patients, including 35 women and 29 men, were selected. After recording the demographic information, a bronchoalveolar lavage (BAL) sample was prepared by the physician from these patients and was immediately sent to the medical mycology laboratory, school of medicine. Bronchoalveolar lavage specimens were investigated by Grocott-Gomori's methenamine silver (GMS) staining and culture method. Data were analyzed by SPSS software, version 16 (IBM SPSS, Armonk, NY, USA).
Results: Of 64 patients, 9 (14%) were infected with pulmonary fungal infections. Among the patients infected with fungal infection, 9 (100%) were positive in the culture examine and 8 (72%) by GMS staining. Among infected people, 7 (77.8%) were female and 2 (22.2%) were male. The most common isolated fungi were Candida albicans, Aspergillus fumigatus and Mucor species (2 cases). The highest infection was seen in the age group of less than 60 (33.3%). 66.7% of infections were among the unemployed persons and 33.3% of other cases of infection were seen in people with free jobs, workers and employees. The most important factors in the development of pulmonary fungal infections in the patients were: 5 cases of malignancy (33.3%), corticosteroid use in 2 cases (33.3%), tuberculosis in 1 case (22.2%) and diabetes mellitus in 1 case (11.2%). There was no significant relationship between fungal contamination with sex, age, occupation, marriage and type of disease.
Conclusion: The results of this study showed that immunocompromised patients are prone to fungal infections, especially Candidiasis and Aspergillosis. Therefore, the use of control methods to reduce the probability of such patients to fungal infections should be considered.
Methods: This descriptive cross-sectional study was conducted in immunocompromised patients suspicious of pulmonary infections referring to specialized lung clinic of Amir-Al-Momenin University Hospital in Arak City, Iran, from April 2017 to June 2018. Of these 64 patients, including 35 women and 29 men, were selected. After recording the demographic information, a bronchoalveolar lavage (BAL) sample was prepared by the physician from these patients and was immediately sent to the medical mycology laboratory, school of medicine. Bronchoalveolar lavage specimens were investigated by Grocott-Gomori's methenamine silver (GMS) staining and culture method. Data were analyzed by SPSS software, version 16 (IBM SPSS, Armonk, NY, USA).
Results: Of 64 patients, 9 (14%) were infected with pulmonary fungal infections. Among the patients infected with fungal infection, 9 (100%) were positive in the culture examine and 8 (72%) by GMS staining. Among infected people, 7 (77.8%) were female and 2 (22.2%) were male.

Abstract
Background: Scleroderma is a chronic systemic disorder that affects the connective tissues. It is characterized by several immune manifestations, inflammation, vascular damage, and fibrosis. Some of the viral infections with complex mechanisms are involved in the development and progression of many autoimmune diseases, such as scleroderma. The present study aimed to investigate the serological prevalence of hepatitis B virus (HBV), hepatitis C virus (HCV), human immunodeficiency virus (HIV), Epstein-Barr virus (EBV), and cytomegalovirus (CMV) infections in Iranian patients with scleroderma.
Methods: In this descriptive study 65 patients with scleroderma and 65 healthy individuals who had no autoimmune diseases and matched for age and sex, from May 2017 to April 2018 at Shiraz HIV/AIDS Research Center, Shiraz University of Medical Sciences, Shiraz, Iran, were included. The serum of study participants were evaluated for cytomegalovirus specific immunoglobulin G (CMV-IgG), Epstein-Barr virus viral capsid antigen immunoglobulin G (EBV-VCA-IgG), hepatitis B surface antigen (HBsAg), hepatitis C virus antibody (HCVAb), and human immunodeficiency virus antibody (HIVAb) using commercially available the enzyme-linked immunosorbent assay (ELISA) kit.
Results: CMV-IgG was diagnosed in serum of all patients with scleroderma, while 49 (98%) healthy subjects had positive results for this test. In addition, EBV-VCA-IgG was diagnosed in 58 (89.2%) sclerodermic patients and 40 (80%) healthy subjects. The prevalence of CMV-IgG and EBV-VCA-IgG was not significantly different between patients and healthy subjects and had no significant relationship with age and sex. However, the titer of antibodies against CMV and EBV infections in the scleroderma group was higher than that in the control group (P<0.0001, and P<0.0001), respectively. The presence of HBsAg and HIVAb was not confirmed in any of the patients with scleroderma, but HCVAb was detected only in one patient. All of the individuals in control group were serologically negative for HBsAg, HCVAb, and HIVAb.
Conclusion: Serological prevalence of HBV, HCV, HIV, EBV, and CMV infections in patients with scleroderma is similar to the healthy group.

Abstract
Background: Intrauterine infections (TORCH) lead to the involvement of various organs of the body of the fetus, including the eye. The aim of this study was to determine the frequency and clinical response of eye lesions to specific drugs, in infants with confirmed TORCH induced ocular lesions.
Methods: This historical cohort study from 2011 to 2017, had done in Pediatrics and Ophthalmology Department of Rasoul Akram Hospital, Tehran, Iran. Cases included; 78 infants with confirmed intrauterine infection (TORCH) with ophthalmologic disorders (glaucoma, cataract, and retinitis), 3 cases died (without any treatment). The cases with incomplete diagnosis, no treatment or without follow-up excluded from study. Out of 74 children with confirmed TORCH induced ophthalmologic disorders, finally 37 children (25 cytomegalovirus, 12 toxoplasma) were treated with specific drugs, and clinical response to treatment was followed-up to 1 year by ophthalmologic examination.
Results: From 12 cases with ophthalmologic disorders due to congenital toxoplasmosis, 5 cases had full treatment, 4 cases had complete response. One case had not any improvement. From 25 cases with congenital cytomegalovirus (CMV), 18 patients continued treatment, 9 cases with complete clinical response, 9 cases had not response to antiviral treatment, indeed most non responder cases had central nervous system involvement from birth. The best response observed in CMV infected cases accompanied with sensory hearing loss (without CNS involvement).
Conclusion: Good clinical response of ophthalmic diseases in 80% of congenital toxoplasma; and 50% of congenital cytomegalovirus infected cases. Probably with initial diagnosis and rapid treatment of cases with TORCH induced ophthalmic disorders (especially cases without CNS involvement) it would lead to stopping ocular lesions.

Abstract
Background: Health care associated infections (HAIs) are a class of infections that infect patients during hospital admissions and receive medical services. These infections occurs within 48 to 72 hours of admission and up to 6 weeks after discharge. Surveillance of device-associated infections (DAIs) in intensive care units (ICUs) is substantial in planning healthcare strategies. This study was conducted to determine the device-associated infections' burden and antimicrobial resistance patterns.
Methods: In this descriptive-analytic study, three common device-associated infections included central line-associated bloodstream infection (CLA-BSI), ventilator associated pneumonia (VAP), and catheter-associated urinary tract infection (CA-UTI), were assessed in intensive care units of Besat Hospital in Hamedan from April 2017 to April 2018. In order to determine the incidence of device-associated infections, the number of device-associated infection cases was calculated during the study period and divided into the number of device-days used. The device-days included all days of exposure to that device (vascular catheter, endotracheal tube (ventilator), or urinary catheter) in all patients in the study population.
Results: Out of 1806 intensive care unit admitted cases, 168 patients (9.3%) were device-associated infection with distribution of 92 cases (55%) of ventilator-associated pneumonia (VAP), 56 cases (34%) of catheter-associated urinary tract infection (CA-UTI) and 20 cases (11%) of central line-associated bloodstream infection (CL-BSI). The incidence of VAP, CA-UTI and CL-BSI was 44.7, 17.5, and 21.61 days, respectively. The most organisms were Acinetobacter (27.4%), Klebsiella (18.3%), Escherichia coli (E. coli) (15.4%). Vancomycin-resistant enterococcus (VRE) was 75%. Acinetobacter resistance to colistin and carbapenem was 16.8%. About half of Pseudomonas isolates were resistant to meropenem.
Conclusion: According to the present findings of this study, a high incidence of device-associated infections and resistant organisms in our intensive care units were documented, which represents a need to reinforce the preventive and control programs. Various results in different studies can be due to differences in the level of health care in different centers and countries.

Abstract
Background: Human papillomavirus (HPV) is a large group of DNA viruses that cause skin and mucosal warts. Zinc is used in the treatment of skin diseases. Zinc has been used in the treatment of various skin and systemic diseases. Warts are benign proliferation of the skin and mucosa. The prevalence of skin warts is higher in children and its peak is in adolescence and then decreases with age. Some species of HPV can cause malignancies. The effective role of zinc in the treatment of warts has recently been discussed. This study aimed to evaluate the serum zinc levels in patients with cutaneous warts compared to healthy controls.
Methods: This case-control study was performed on patients, aged 18 to 60 years old, referred to the Dermatology Clinic of Bo’Ali Sina and Razi Hospitals, Mazandaran Province in, Iran, from April to March 2016. Serum zinc level and severity of disease were assessed in case and control groups. Data were analyzed by SPSS software, version 22 (SPSS Inc., Chicago, IL, USA).
Results: A total of 94 subjects (47 in the case and control group) entered the study. The mean age of the case group was 26.40±9.33 years and in the control group 28.32±7.35 years. The gender status was 42 (44.7%) male and 52 (56.3%) female. Single and married were 63.8% and 36.2%, respectively. The mean zinc level in patients with cutaneous wart was 82 and the control group was 85.65. The mean number of warts was 5.09±6.33. The most frequent site of lesions were on the hands and foot with 48.93% and 40.42%, respectively, and the face (3.2%) had the lowest rate. Almost half of the patients were affected by the disease for 12 to 18 months. There was no significant relationship between age, sex, and severity of disease with serum zinc level (P>0.05). Serum zinc level was significantly associated with the duration of warts involvement (P=0.043).
Conclusion: Serum zinc levels were lower in patients with cutaneous warts than in healthy controls, but this difference was not statistically significant. Serum zinc level and duration of warts involvement were related. The duration of warts and serum levels were inversely correlated.
