RESUMEN
PURPOSE: Hepatitis C is one of the major health issues in both developed and developing countries. Hepatitis C virus (HCV) infection is more common in prisoners than in the general population. The purpose of this study was to determine the prevalence of HCV and its associated risk factors in Iranian male prisoners in Tehran. DESIGN/METHODOLOGY/APPROACH: In this cross-sectional study, the authors investigated the frequency and risk factors of hepatitis C infection among male prisoners in the Great Tehran Prison. Information on risk factors including the length of imprisonment, previous history of imprisonment, history of drug injection, history of tattooing, history of piercing, history of high-risk sex and family history of hepatitis C were extracted from patients' records. To evaluate HCV status, blood samples were collected and tested. FINDINGS: In this study, 179 participants were included. Nine participants (5.0%, 95% CI, 2.3-9.3) were positive for hepatitis C. HCV infection was not significantly associated with age, marital status, education, previous history of imprisonment, length of imprisonment, piercing and high-risk sex; however, there was a significant association between a history of tattooing and a history of injecting drug use and Hepatitis C. ORIGINALITY/VALUE: The prevalence of hepatitis C among male prisoners in Great Tehran Prison was 5% in this study, similar to recent studies on prisoners in Tehran. A history of drug injections as well as tattooing were the most important risk factors for hepatitis C in male prisoners.

Background and Aims: Immunosuppressive therapy has a key role in developing coronavirus disease-2019 (COVID-19)-associated mucormycosis. In this study, we investigated the effect of the type and cumulative dose of immunosuppressive agents on COVID-19-associated mucormycosis. Methods: We designed a descriptive cross-sectional study involving three COVID-19 hospitals in Iran. Clinical and demographic data were gathered from the medical records and checked by two independent researchers to minimize errors in data collection. Results: Seventy-three patients were included in the study. The mean age of cases was 57.41 (SD = 12.64) and 43.8% were female. Among patients, 20.5% were admitted to the intensive care unit (ICU) during COVID-19. Furthermore, 17 patients (23.29%) had a history of diabetes mellitus. Sixty-nine patients (94.52%) had a history of receiving corticosteroids (dexamethasone) during treatment of COVID-19, and of those, five patients (6.85%) received Tocilizumab beside. The mean cumulative dose of corticosteroids prescribed was 185.22 mg (SD = 114.738). The average cumulative dosage of tocilizumab was 720 mg (SD = 178.89). All of the included patients received amphotericin B for mucormycosis treatment, and 42 survived (57.53%). Also, there was a significant relationship between hospitalization in ICU for COVID-19 and the mucormycosis outcome (p = 0.007). However, there weren't any significant associations between cumulative doses of immunosuppressive drugs and mucormycosis outcome (p = 0.52). Conclusion: The prevalence of COVID-19-associated mucormycosis is increasing and should be considered in the treatment protocols of COVID-19. Controlling risk factors such as diabetes, malignancy and the administration of immunosuppressive agents based on recommended dosage in validated guidelines are ways to prevent mucormycosis.
RESUMEN
Abstract Introduction The nasopharynx and oropharynx are the main colonization sites of coronavirus. Therefore, patients with paranasal sinuses and pharyngeal problems (ear, nose, and throat [ENT] patients) predispose coronavirus infection. Ear, nose, and throat patients with concomitant asymptomatic coronavirus infection may develop severe pneumonia following surgical procedures. As a result, presurgical screening for coronavirus infection is a substantial concern. Objective We evaluated the usefulness of a spiral chest computed tomography (CT) scan in the diagnosis of asymptomatic coronavirus infection in the presurgical assessment of ENT patients Methods In this study, candidates of paranasal sinus or pharyngeal surgery were evaluated for coronavirus infection. Patients with neither history of coronavirus disease 2019 (COVID-19) nor compatible symptoms and signs were screened for asymptomatic coronavirus infection. These patients composed two groups: the first group underwent a reverse transcription polymerase chain reaction (RT-PCR) test of nasopharyngeal sample and spiral chest CTscan, but for the second one, only the latter was performed. Results In the first group, which consisted of 106 patients, 11 (10.4%) cases had positive RT-PCR test results, and 17 (16%) patients showed positive findings in favor of coronavirus infection in the spiral chest CT scan. In the second group, which consisted of 173 patients, 34 (19.7%) cases had positive chest CT scan results. Conclusion The chest CT scan has a valuable role in the early diagnosis of asymptomatic coronavirus carriers in patients highly predisposed to infection, especially in low resource areas, where the RT-PCR test is unavailable.

RESUMEN
While we are still learning about COVID-19 affecting people, older persons and persons with underlying diseases such as high blood pressure, heart disease, and diabetes mellitus (DM) appear to develop serious illness and more complications often than others. In this report, we presented a patient with spontaneous pneumomediastinum after COVID-19. The patient was a 61-year-old man with a history of DM, hypertension, and heart failure, who has been infected with COVID-19. The patient was diagnosed with COVID-19 based on RT-PCR analysis of nasopharyngeal samples, and chest X-ray showed patchy infiltration upper and lower lobes bilaterally. By day 4, imaging was repeated, performed due to exacerbation of pleuritic chest pain, decreased O2 saturation (80%), and coughing that revealed multiple ground-glass opacities bilaterally, and interlobular septal thickening with emphysema in most of the left upper lobe and a small part of right upper lobe which led to severe spontaneous left pneumomediastinum and parenchymal consolidation was also observed. The combination of a chest tube, antibiotics (vancomycin 1 gr/bid and meropenem 1 g/bid), and antiviral (hydroxychloroquine 200 mg/bid and atazanavir 300 mg/daily) was prescribed, and continued treatment with antiviral and appropriate care for pneumomediastinum was successful. Spontaneous pneumomediastinum in the context of COVID-19 should be considered as a prognostic factor in favor of worsening diseases.
RESUMEN
Convalescent plasma (CP) therapy has been suggested as a treatment for emerging viral diseases. Moreover, many studies have been conducted to evaluate the efficacy of COVID-19 CP therapy, with some of them indicating that CP may be a promising treatment for the disease. However, the evidence for CP therapy's effectiveness in severe COVID-19 cases is limited. So, this study aimed to assess the probable effects of CP therapy in patients diagnosed with severe COVID-19. The study was designed as a single-arm, retrospective cohort of patients with severe COVID. Demographic data, laboratory test reports, and convalescent plasma transfusion doses were collected from medical records for patients before and after convalescent plasma transfusion. The clinical outcomes were hospital discharge and death. Also, laboratory parameters considered secondary outcomes. After CP therapy, some symptoms improved, especially in patients under 55 years old, as follows. Respiratory function was significantly enhanced after convalescent plasma transfusion, and the inflammatory biomarkers' values decreased significantly (p < 0.05). Moreover, the estimated median of partial thromboplastin time (PTT) and Prothrombin time (PT) in patients did not change after CP therapy (p > 0.05). Regarding COVID-19 mortality, a strong association was found between older ages and death (p < 0.001). Also, CP transfusion in the early days of admission was effective in treatment outcomes (p = 0.023). Other characteristics, including sex, blood group, number of CP transfusions, and preexisting conditions, did not significantly correlate with mortality. In conclusion, this study demonstrates the effectiveness of CP therapy in patients under the age of 55. Despite some improvement, we could not say that they were entirely due to the CP treatment. More extensive randomized clinical trials that cover different stages of the disease are needed.

BACKGROUND: We reported a case of multiple sclerosis (MS) with persistent symptomatic COVID-19, which was complicated by new-appearing severe pneumonia 40 days after disease onset. CASE PRESENTATION: A 38-year-old man with a history of multiple sclerosis referred to our hospital with fever, shaking chills, cough, and dyspnea. In his history, the patient had developed mild COVID-19 from 40 days ago. After 7 days of disease onset, the COVID symptoms had been subsided partially, but fatigue, myalgia, intermittent fever, and loss of taste and smell had been continued. In physical examinations, his oral temperature was 39.4 °C. He had respiratory distress, and his blood oxygen saturation on the room air was 90%. The spiral chest CT scan was performed, which revealed bilateral ground-glass and alveolar opacities in favor of COVID-19 pneumonia. The result of the RT-PCR test for SARS-COV-2 was reported positive subsequently. His current MS medication was rituximab and he had received the last dose of rituximab two months before developing COVID-19. The patient was admitted to the COVID ward and put on Remdesivir, subcutaneous interferon-beta1b, and dexamethasone. He improved gradually and was discharged from the hospital with the favorable condition after 10 days. This patient had a rare protracted disease course. We presumed that prolonged high degree fever (above 38 °C) in our patient is beyond the diagnosis of the post-COVID-19 syndrome and is more compatible with persistent infection. CONCLUSION: Although most immunocompromised patients effectively clear SARS-CoV-2 infection, this case report highlights the risk of persistent infection associated with recurrence of the disease.

BACKGROUND: An increase in resistant gram-positive cocci, especially enterococci, requires an epidemiologic re-assay and its results may affect empirical treatments for these infections. OBJECTIVE: In this study, we investigated the microbial epidemiology and resistance pattern of enterococcal bacteremia. METHODS: This study was a cross-sectional study that investigated all cases of positive blood cultures with Enterococcus spp. at a tertiary referral colligates hospital in Tehran in 2018. RESULTS: Enterococcus spp. was isolated from blood cultures of a total of 73 patients. Most of the patients were male i.e: 42 (57.7%). The mean age of the patients was 58.8 (±18.8) years. Hospital- acquired infection was the most prevalent type of infection involving enterococcal bacteremia (80.8%) compared with community-acquired (6.7%) and the health care-associated one (12.3%). Renal failure and cancer were the most underlying disease in E. faecalis and E. faecium, respectively. Mortality for Vancomycin-resistant enterococci (VRE) was approximately two times more than the sensitive ones. Between the dead/alive groups, the following items were significantly different (P.Value<0.05): Vancomycin resistance for enterococcus isolated, immunodeficiency as an underlying disease, Mechanical ventilation, hospitalization period, and the empiric regimen. CONCLUSION: Increased antibiotic-resistant strains, especially Vancomycin-resistant enterococci (VRE), pose a serious threat to the general public, especially hospitalized patients, causing an increase in mortality. Surveillance of microorganisms and antimicrobial resistance is a crucial part of an efficient health care system.

BACKGROUND AND AIMS: The kidney transplant patients who receive immunosuppressive and specific medication may lead to different mortality risk factors between kidney transplant patients with COVID-19 and the general population. We aimed to provide a model predictor and a risk analysis of mortality in kidney transplant COVID-19 positive patients. METHODS: We performed our search using PubMed, MEDLINE, Web of Science, Scopus, and Google Scholar to identify English articles published from the beginning of December 2019 through August 2020. Excluded manuscripts had no full text, lacked information, were not the original article, or consisted of less than three cases. We gathered information about demographic information, comorbidities, COVID-19 symptoms, lung radiographic findings, history of medication therapy, and changes in the kidney maintenance therapy after confirming their COVID-19 on the data extraction forms. RESULTS: We found a total of 31 eligible articles. We set a 10% mortality rate as our cutoff point. The most common sign and symptoms were cough (53.22 [29.42]), dyspnea (50.80 [24.55]). In the bivariate analysis, fatigue (P = .04, OR of 0.92; 95% CI: 0.85-1.00), hypertension (P = .07, OR of 1.03; 95% CI: 1.00-1.07), and dyspnea (P = .08, OR of 1.04; 95% CI: 1.00-1.09) showed a statistically significant relationship with increases in mortality.In multivariate regression analysis, an independent association was only found between hypertension and mortality (P = .035; AOR of 1.064; CL: 1.004-1.127). CONCLUSION: Clinicians should pay special attention to modifiable risk factors for COVID-19 infection mortality, such as hypertension among kidney transplant patients, because it may be possible to decrease mortality by controlling these factors.
RESUMEN
INTRODUCTION: Seasonal influenza is an annual common occurrence in cold seasons; but the COVID-19 pandemic is also currently ongoing. These two diseases can't be distinguished from their symptoms alone; therefore, the importance of preventing influenza by vaccination is more than ever. Due to the high exposure of hospital personnel, widespread influenza vaccination of these high-risk groups seems to be a necessity. This Study conducted to determine vaccination coverage in the personnel of four tertiary referral collegiate hospitals in 2019 and to further investigate individual obstacles for Influenza vaccination. METHODS: In this cross-sectional descriptive study, 637 personnel were selected randomly from distinctive hospitals in a list-wised. Ones vaccinated filled the side effects questionnaire and who not vaccinated filled the vaccination obstacles questionnaire. The study was approved by the ethics committee of Tehran University of Medical Sciences with this reference number: IR.TUMS.IKHC.REC.1398.218. RESULTS: The mean vaccination coverage was 29.4% and the coverage difference among centers was not statistically significant (p = 0.192). The following items had the most impact on personnel decision: confidence about one's immune system (p < 0.05), the experience of side effects from previous vaccinations (p = 0.011), attitude about vaccination in colleagues (p = 0.021) and work experience (p < 0.05). About 23% of vaccinated individuals reported side effects following vaccination and the most common side effect was mild cold symptoms with 12.3% prevalence. CONCLUSION: The results of the current study revealed that influenza vaccination coverage among HCWs is not satisfactory in Iran. Hospital authorities and infection control units should plan to remove the obstacles of influenza vaccination.

BACKGROUND: Sexual minorities, such as men who have sex with men (MSM), are disproportionately impacted by HIV/AIDS compared to heterosexual men. The increased prevalence of HIV/AIDs among this group of individuals is associated with increased participation in HIV-related risk behavior, such as multiple sexual partnerships and injection drug use. However, very little is known about the prevalence of HIV and the risk behaviors related to HIV infection among MSM in Iran. This absence of data is due to the increased discrimination and stigmatization MSM, and other vulnerable populations face in Iran. This study was conducted to identify HIV-related risks, HIV prevalence and sociodemographic characteristics of the MSM population in Iran. METHODS: A cross-sectional study was conducted among MSM attending the Sexual Health Clinic at Imam Khomeini Hospital in 2018. A sexual health screening questionnaire was used to aid in identifying HIV-related risk behaviors. HIV status was determined using an HIV rapid test and confirmed by an ELISA. RESULTS: One hundred MSM enrolled in this study, out of which 41% were 18-25 years old. The majorities were single; almost one-third had a diploma degree. Only a fifth were employed, and about a quarter (25%) reported substance abuse. Among eighty-three people (83%) reported having sex during the past three months, and only 27 (27.3%) of participants always used condoms for sex. Among 80 participants tested for HIV, two positive results were detected (2.5%). CONCLUSION: Data collected through a sexual health questionnaire indicated that the prevalence of HIV is increased among MSM in Iran. This finding sheds light on the urgent need for the implementation of social programs providing counseling and healthcare to vulnerable populations in Iran.

Infectious mononucleosis (IM) due to Epstein-Barr virus (EBV) infection is usually self-limited. It presents with fever, pharyngitis, fatigue, and cervical lymph node enlargement. It is common among adolescents and young adults. Although most patients recovered without any sequelae, rare complications have been reported. We described a 28-year-old man with fever, sore throat, dysphagia, and a positive IgM viral capsid Ag (VCA Ag) for EBV infection. He was admitted and received dexamethasone. He developed bilateral peritonsillar abscess (PTA) and splenic infarction, rare complications of acute EBV infection, two days after discharge. Although early reports noted PTA might occur following dexamethasone administration, recently, no obvious evidence supports it. However, high erythrocyte sedimentation rate level in our patient might indicate bacterial superinfection, which could exacerbate with dexamethasone administration. Several mechanisms such as transient hypercoagulable state and insufficient blood supply due to splenomegaly were proposed for splenic infarction due to EBV infection. Since our patient remained asymptomatic during the disease, IM-associated splenic complications, including splenic infarction, should be kept in mind. Our patient underwent bilateral tonsillectomy and received conservative management for the splenic infarction. These two rare complications of acute EBV infection have not been reported simultaneously yet.
RESUMEN
At the beginning of 2020, a newly emerged virus, now named SARS-CoV-2, began to spread in China. After four months, it has reached all over the globe, infecting more than 2.5 million people. Currently, there are no proved treatments available. However, in social media, false information about alcohol consumption and its role against the virus is spreading. We described a victim of these false facts, who was present with reduced eyesight due to alcohol drinking. A few days later, he showed symptoms of COVID-19 and, even though received treatment, lost his eyesight partially. Alcohol taking has no preventive or curative effect on COVID-19 and negatively impacts the body and immune system, which, therefore, should not be considered a treatment for COVID-19 disease.

BACKGROUND: The recent outbreak of the coronavirus disease (COVID-19) in China has rapidly spread throughout the world and there are many reports of symptoms ranging from malaise to acute respiratory distress syndrome (ARDS) caused by this infection. However, few reports have been discussed surgical outcomes in COVID-19 patients. CASE PRESENTATION: In this report, we described a case of an elderly female developed with postoperative pulmonary complications after uneventful elective minor surgery. The patient was asymptomatic before the operation with no history of cough or fever. After surgery, the patient developed respiratory distress and chest radiological imaging revealed bilateral ground-glass opacities. It seems any type of surgeries requiring local anesthesia or general anesthesia may contribute to worsening outcomes in patients with covid19.

Objective: Depression affects people living with HIV (PLWH) compliance leading to poor control infection. Previous observational studies showed an anti-depression effect of green tea extract (GTE). The therapeutic effect of GTE on depression were investigated in PLWH receiving antiretroviral therapy (ART). Methods: Fifty PLWH on ART with diagnose of mild to moderate of depression, participated in a double-blind, placebo-controlled trial and underwent 12 weeks of treatment with either 400 mg GTE capsules or placebo twice daily. The Hamilton depression scale of patients was measured before, 6 weeks and 12 weeks after treatment in two groups. The primary outcome measure was performed to evaluate the efficacy of GTE in improving depressive symptoms. Results: The mean of Hamilton score showed a significant difference between the two groups after 12 weeks (P = 0.035). Repeated measures ANOVA test showed a significant effect for time × treatment interaction on the Hamilton mean score between the two groups (P = 0.000). Conclusion: It seems the use of GTE capsules in PLWH on ART is safe and could lead to greater and more rapid improvement in depressive symptoms than placebo. Thus it can be considered as an alternative therapy for mild to moderate depression. Further studies with higher sample size and longer follow-up and comparisons with other antidepressive drugs are warranted.
RESUMEN
In patients with COVID-19, certain medical conditions could result in poorer clinical outcomes. However, the prognostic role of hypothyroidism in COVID-19 is still unknown. In the present retrospective study, we estimated the prevalence of hypothyroidism in COVID-19 admitted patients in Tehran, Iran. Among 390 COVID-19 admitted patients, 21 hypothyroid cases (5.4%) were found, in which nearly 90% were aged 50 years and older. Regarding the effect of hypothyroidism on COVID-19 mortality, 60 (15.3%) of total patients and 4 (19%) of hypothyroid patients died, and no significant difference was found between the two groups.

The novel coronavirus SARS-CoV-2 infection is spreading worldwide, and there are many reports of acute respiratory distress syndrome caused by this infection. However, asymptomatic lung involvement has not been reported. We hereby present the case of a 44-year-old health-care worker, who was found to be infected with the SARS-CoV-2 virus after a CT-scan performed for an unrelated condition revealed a lesion in the lung field compatible with COVID-19 infection. His condition deteriorated initially, but eventually improved with supportive treatment and the compassionate use of antivirals and antimalarials and is now in a stable condition.
RESUMEN
Myeloid sarcoma (MS) is a solid extra-medullary tumor of immature myeloid cells which could occur before, during or after remission of acute leukemia at any site on the body. Owing to variation in differential diagnosis, pathologic evaluation and immunohistochemical staining are essential for definitive diagnosis. Rarely, MS has been shown as an isolated extramedullary relapse (iEMR) after allogeneic stem cell transplantation (allo-SCT), which often does not necessarily result in bone marrow involvement. It seems that despite chemotherapy and graft-versus-leukemia (GVL) effects on bone marrow, leukemic cells could remain alive in the extra-medullary region. However, in order to achieve longer survival, timely diagnosis as well as combined systemic, local, and cellular therapeutic modalities should be considered in any patient with iEMR after allo-SCT. We report a left lateral neck isolated MS presented as acute otitis externa in a patient with prior allo-SCT due to acute myeloid leukemia (AML). Therefore, MS should be considered in patients with any history of acute leukemia even if the patient presents with signs and symptoms of an infectious disease.

Cyclosporine is one of the main drugs used for the prophylaxis of graft versus host disease in bone marrow transplanted patients. Hypersensitivity reaction to intravenous cyclosporine is rare and might be due to its vehicle polyoxyethylated castor oil, Cremophor EL. The exact mechanism is unknown, but IgE and IgG antibodies, complement, and histamine release have been considered to play a role in the development of this reaction. Here, we describe a case of anaphylaxis to intravenous cyclosporine, which was developed in a 19-year-old Iranian female with acute myeloid leukemia who underwent allogeneic bone marrow transplantation from her sister. The corn oil-based soft gelatin capsule (Sandimmune®) was substituted with no reaction. Our observation along with the previous reports confirms the role of Cremophor EL in hypersensitivity reaction to cyclosporine, according to which, modifying the formulation of the intravenous (IV) form could be the solution for this problem.
