Clinical Research Development Unit, Shahid Mostafa Khomeini Hospital, Ilam University of Medical Sciences, Ilam. Iran.

Introduction: COVID-19 has caused a great deal of fear indifferent communities. In this study, we reported the recovery of a diabetic elderly woman with a history of asthmafromCOVID-19 infection.

Case Presentation: A 61-year-old woman was hospitalized due to dyspnea and low blood O2 saturation and later diagnosed with COVID-19, as confirmed by PCR. The patient had a history of asthma and diabetes and used salbutamol and Atrovent spray. She also had a history of hospitalization at one month prior to the current admission. Despite all these, COVID-19was successfully managed, and she was discharged with a good clinical condition after the improvement of respiratory complications.

Conclusion: Despite having an advanced age and underlying diseases (diabetes and asthma), the recovery of this elderly woman shows that even such patientscandefeatCOVID-19 as long as the disease is not progressed to advanced phases and appropriate therapeutic measures are taken. By reporting such cases, it is possible to give people hope and motivation and reduce their fear of the disease.

Sudden cardiac death in COVID-19 patients, a report of three cases.

Future Cardiol 2021 01 3;17(1):113-118. Epub 2020 Jul 3.

Associate Professor of Cardiology, Department of Cardiology, Imam Khomeini Hospital Complex, Tehran University of Medical Sciences, Tehran, Iran.

The mortality rate of coronavirus disease-19 (COVID-19) has been reported as 1-6% in most studies. The cause of most deaths has been acute pneumonia. Nevertheless, it has been noted that cardiovascular failure can also lead to death. Three COVID-19 patients were diagnosed based on reverse transcriptase-polymerase chain reaction of a nasopharyngeal swab test and radiological examinations in our hospital. The patients received medications at the discretion of the treating physician. In this case series, chest computed tomography scans and electrocardiograms, along with other diagnostic tests were used to evaluate these individuals. Sudden cardiac death in COVID-19 patients is not common, but it is a major concern. So, it is recommended to monitor cardiac condition in selected patients with COVID-19.

Virology 2020 09 25;548:1-5. Epub 2020 May 25.

Clinical Research Development Unit, Shahid Mostafa Khomeini Hospital, Ilam University of Medical Sciences, Ilam, Iran. Electronic address:

Introduction: During the recent months, COVID-19 has turned to a global crisis claiming high mortality and morbidity among populations. Despite the high prevalence of the disease, it has currently no definitive treatment. We here reported the effects of intravenous immunoglobulin (IVIG) administration in severely ill COVID-19 patients diagnosed based on PCR and radiology tests.

Case Presentation: Five severely ill COVID-19 patients in whom standard treatments failed were administrated with IVIG which prevented the deterioration of clinical symptoms. All the patients were treated with high-dose IVIG (0.3-0.5 g/kg) for 5 consecutive days so that no patient would receive lower than 25 g of the drug. All the patients showed a desirable therapeutic response and were discharged from the hospital with a stable clinical condition after being recovered.

Conclusion: Treatment with IVIG at the therapeutic dose of 0.3-0.5 g/kg can improve the clinical condition and O2 saturation and prevent the progression of pulmonary lesions in COVID-19 patients with severe symptoms in whom standard treatments have failed.

J Res Med Sci 2019 28;24:76. Epub 2019 Aug 28.

Faculty of Nursing and Midwifery, Student Research Committee, Ilam University of Medical Sciences, Ilam, Iran.

Background: Many causes can lead to childhood rickets. We aimed to investigate the biochemical symptoms of childhood rickets with systematic review and meta-analysis.

Materials And Methods: Seven articles published from 1975 to 2018 were recruited. The literature search was performed in the Scientific Information Database, Google Scholar, PubMed, and Elsevier databases using related keywords. For meta-analysis, the results of the studies were pooled using the random-effects model. The heterogeneity between the studies was checked using test and index.

Results: The total sample population consisted of 933 children with biochemical symptoms of rickets (133 participants per article). According to our findings, the mean serum levels of PO, Ca, and alkaline phosphatase in children with rickets were 4.18 (95% confidence interval [CI]: 3.75-4.61, = 98.3%, < 0.001), 9.23 (95% CI: 8.78-9.68, = 99.6%, < 0.001), and 1.33 (95% CI: 1.23-1.44, = 95.6%, < 0.001), respectively.

Conclusion: Characterizing the biochemical symptoms of rickets in children can help to early diagnose and prevent the disease in children. Furthermore, educating parents about biochemical symptoms can lead to early diagnosis and successful treatment of rickets in children.

Indian J Palliat Care 2019 Jan-Mar;25(1):147-152

Psychosocial Injuries Research Center, Ilam University of Medical Sciences, Ilam, Iran.

Context: Diseases and accidents bring about the disorder at someone's job insofar as one is not able to return to her/his previous work. These cases are related to the amount of occurred accidents, type of disease, and one's job.

Aim: The aim of this study was to evaluate the factors that affect return to work (RTW) in cancer survivors using a systematic review and meta-analysis design.

Methods: This is a systematic review and meta-analysis study. We searched the PubMed, Scopus, SID, Google, Elsevier, Google Scholar and Web of Science databases using following keywords: Return to work, cancer patients, employment status, cancer survivors from 2002 to 2017. The rate of return to work in cancer patients based on age group and risk factors was calculated using subgroup analysis. Data were analyzed using STATA software (version 11.1).

Results: The total sample size was 4675 people with a mean of 668 in each study. The frequency of studies in the world consists mainly of five studies (71.5%) from Europe continent (the Netherlands and Denmark) and two studies (28.5%) from Asia continent (Iran and Japan). The overall rate of RTW estimated at 72% (68%-77%). The percentage of RTW in Asia and Europe was 57% (50%-65%) and 52% (43%-60%), respectively. Surgery had the highest percentage of treatment options in patients with cancer with 46% (25%-68%), followed by radiotherapy and chemotherapy with 37% (29%-46%) and 36% (23%-49%), respectively. Breast cancer and gastrointestinal cancer were the most and less common type of cancers with 36% (19%-54%) and 16% (7%-26%), respectively.

Conclusion: The overall rate of RTW estimated at 57%. Nonetheless, the faster diagnosis and regular screening could improve the survival rate of cancer patients and the increase of RTW.

J Inj Violence Res 2017 01 1;9(1). Epub 2017 Jan 1.

Department of Nursing, Psychosocial Injuries Research Center, Ilam University of Medical Sciences, Ilam, Iran. Email:

Background: Workplace violence against female nurses is an increasing problem. In addition, recognition the rights of patients can reduce such violence against female nurses. Therefore, the aim of the current study was to investigate workplace violence against female nurses in respect with patients' bill of rights at two public hospitals of Ilam in 2012.

Methods: In a descriptive cross-sectional research, workplace violence against female nurses was studied. Data were gathered employing a researcher made questionnaire filled out by 106 female nurses. The questionnaire was on workplace, physical and verbal violence of patients and their attendants, and also the patient's rights as respected by nursing staff. Permission of university ethics committee was obtained. Data analyses were done by T-test and ANOVA in SPSS software.

Results: Totally, 90.6 % and 15.1 % of the participants were subjected to verbal and physical assaults by patients, respectively during last year of the study. Further, 92.5% and 11.3% of nurses experienced verbal and physical assaults by the patients' attendants, respectively. Most of the nursing staff believed that reporting aggressive attacks to the concerned officials would not be useful. A negative significant correlation was found between the aggressions of patients with age as well as marital status of nurses, (P= 0.04). Furthermore, a significant association was seen between physical violence of patients and the nurses' recognition of the patients' bill of rights (P= 0.03).

Conclusions: Due to high rate of violence against female nurses, some proper and effective actions such as employing a trained security force along with legal punitive charges against violators through responsible officials are highly suggested.

Prevalence of epilepsy in iran: a meta-analysis and systematic review.

Iran J Child Neurol 2014 ;8(4):9-17

The Clinical Practice Unit, The Queen Elizabeth Hospital, Adelaide, Australia.

Objective: Epilepsy is one of the most common diseases in Iran contributing to an array of health problems. In light of this, the aim of the present study is to examine the prevalence of epilepsy in Iran through a systematic review and meta-analysis.

Materials & Methods: A systematic search of several databases including PubMed, scientific information databases, Google, Google scholar, Elsevier and Scopus was conducted in June 2013. Observational studies were considered for inclusion if they were published in Iranian and examined epilepsy prevalence and/or related risk factors. Meta-analysis was conducted using a random effect model with the DerSimonian/Laird method. Heterogeneity was examined using the Breslow- Day test and inconsistency using the I2 statistic.

Results: A total of 45 studies were identified from the search strategy. Of these, nine published manuscripts with a total of 7,723 participants were included within the review. The pooled prevalence of epilepsy in Iran was estimated to be around 5% (95% confident interval (CI) 2 to 8). For each region the prevalence of epilepsy in central, northern and eastern Iran were 5% (95%CI 2 to 8), 1% (95%CI -1 to 3) and 4% (95%CI 3 to 11) respectively. The most common risk factors in order of prevalence were somatic diseases 39% (95%CI 15 to 62), convulsion 38% (95%CI 11 to 65), mental diseases 36% (95%CI 15 to 95) and hereditary development 26% (95%CI 9 to 42). A meta-regression model identified a declining trend in the prevalence of epilepsy within Iran for the last decade.

Conclusion: Pooled analyses from the nine included publications in this review estimate the prevalence of epilepsy in Iran to be around 5%. Although this result is much higher than rates in other countries, a declining trend in prevalence over the past decade was also identified.
