Volume 73, Issue 8 (November 2015)
Abstract

Background: There is a concern by some doctors that not interrupting the patients' initial statements of concerns can lead to too long medical visits. Therefore, in this study, the duration of the patients' initial statements of concerns was studied. Methods: This descriptive cross sectional study was conducted from August to October, 2011 in the Emergency Department of Imam Khomeini Hospital in Tehran. 100 patients entered the study through convenience sampling. Based on a 5 level triage system Emergency Severity Index (ESI), patients who were not life-threatening conditions (level 5) entered the study and critically ill patients and foreign patients were excluded from the study. Demographic data of the patients and durations the patients' initial statements of concerns were recorded and measured. Results: Fifty-six percent of patients were men. 79 percent of them had academic degree less than diploma and most of them have Persian ethnicity (60 percent). The mean age of the participants was 37.09 (SD, 1.68). The mean durations of patients' initial statements was 71.60±2.37 seconds. The minimum time was 22.51 seconds and the maximum time was 206.51 seconds. There was significant difference between age (P=0.001, r=0.382) and gender (P=0.032, df=98, t= -2.17) with the durations of patients' initial statements. But education level (P=0.996, F (2, 97)=0.004) and ethnicity (P=0.266, F (6, 93)=1.3) did not have a significant effect on the durations of patients' initial statements. Conclusion: According to the findings of this study, duration of patients' initial statements of concerns is less than what which leads to an increase the time of medical visits.

Abstract

Background: One of the today most common and incurable diseases that is associated with central neural system is ‘MS’ disease. Multiple sclerosis (MS) is a demyelinating disease in which the insulating covers of nerve cells in the brain and spinal cord are damaged. In this disease become apparent a wide spectrum of symptoms such as lose muscles control and their coordination and vision derangement. The goal of this research is to consider to two problems: 1- Recognition of effective clinical symptoms on MS disease and 2- Considering levels of effectiveness of age, sex and education levels factors on MS disease and association between these factors according to verity of categories of this disease.

Methods: Data mining science in medicine is worthy of attention with main application in diagnosis, therapy and prognosis, respectively high volume of collected datum. The data that were used in this article are about patients of Chaharmahal and Bakhtiari Province and collected by cure assistance. In this paper classification and association methods in software engineering field are used. Classification is a general process related to categorization, the process in which ideas and objects are recognized, differentiated, and understood. Association rules are created by analyzing data for frequent if/then patterns and using the criteria support and confidence to identify the most important relationships.

Results: In consideration of first problem in this paper, concluded vision-clinical symptoms are the most effective symptoms and in consideration of second problem, concluded that from 584 records, women affected four times more than men. In other word 70% of MS patients with high graduate are in relapsing-remitting category and 62.5% of MS patients are 20-40 years old.

Conclusion: Some of symptoms are quite temporary and transitory and are ignored by people. Awareness of clinical-symptoms prevalence manner can be warning for people before starting critical cycle of illness. This would cause early diagnosis, effective therapy and even prevention of disease progress, respectively to MS chronicity.

Abstract
Historically, tuberculosis has been the leading cause of death throughout human history. Tuberculosis infection (TB) causes by Mycobacterium tuberculosis that is very dangerous and can affect any parts of the body, especially lungs. Tuberculosis infection still remains a serious threat to human public health due to its contagious nature, capability to stay latent form in host for indefinite time and then appear as active disease. It is estimated that one third of world’s population, nearly 2 billion persons are infected with Mycobacterium tuberculosis. Transmission occurs among people through inhalation of infected droplets. Lungs and especially alveolar macrophage are primary sites of infection. Mycobacterium tuberculosis bacilli by preventing fusion of phagosome with lysosome can remain alive inside the macrophages. Such situation defined as latent infection. In fact, persons with latent tuberculosis infection (LTBI) are only infected with M. tuberculosis without any sign of infectious. Latent infection in compared with active infection is not contagious, but in about 10-5 percent of people will develop active tuberculosis especially in elderly and people who use immunosuppressive drugs. Pulmonary TB is an active form of tuberculosis infection in which bacteria can spread among people by infected droplets. So identifying and treating people with latent TB infection can significantly reduce the progression of latent form to active infection. The tuberculin skin test (TST) is the most widely used test in worldwide that is applied to determine a person who is infected with M. tuberculosis. TST provide valubale information for diagnosis LTBI however its specificity can be reduced by bacillus Calmette-Guérin (BCG) vaccination and infected with non-tuberculous mycobacteria (NTM). In TST test host hypersensitivity responses to Purified protein derivative (PPD) from mycobacterium are evaluated. TST positive reaction indicates the presence of high risk for acquiring TB infection or progression of latent tuberculosis to active form. Previous studies indicated that there is correlation between TST response and subsequent risk of active TB. Experimental evidence has shown that treatment of latent infection in the basis of positive TST reduces the risk of active TB. Although TST is far from gold standard but it's low cost and simplicity make it a suitable laboratory test especially in developing country.

Abstract
Background: The pandemic of Covid-19 is spreading around the world. Extensive research is needed to focus on identifying the underlying causes of the disease. This study aimed to investigate the clinical and etiological symptoms of the Covid-19.
Methods: This descriptive-analytical study, conducted on 510 infected patients in the infectious disease clinic of Imam Khomeini Hospital in Tehran from March 2019 to June 2020 for A period of Four months during the first wave of Covid-19 pandemic. The method of selecting patients was continuous and was divided into two groups of 179 inpatients and 331 outpatients based on lung scan and clinical symptoms. Demographic information, clinical signs, and risk factors were collected through a questionnaire and the data were statistically analyzed.
Results: Symptoms such as fever, chills and cough were reported in the majority of patients in both groups, to such an extent that they were present in 176 (52%) of outpatients and in 101 (59%) of inpatients. The mean hemoglobin measured in hospitalized patients was lower, P=0.001). Vitamin D3 supplementation was reported in 30% of outpatients and in 16.5% of hospitalized patients (P=0.001). This means that vitamin D3 consumption is higher in the outpatient group.
The results showed that Chronic diseases such as hypertension was 4.9 times more likely (OR=4.9, 95% CI2. 433-10.25, P=0.0001) and anemia with 22 times more likely (OR=22.905, 95% CI9. 355-56.083, P=0.000) to be effective in the severity of the disease. It seems Vitamin D3 intake has a supportive effect on reducing the severity of the disease and decreases the risk of the disease getting worse.
Conclusion: Fever, chills and cough were important symptoms in identifying infected patients with Covid-19. According to the results of the present study and the findings of other studies, the supportive effect of vitamin D3 in reducing the severity of infectious diseases should be considered. Clinical trials with appropriate sample size are recommended to investigate the functional role of this vitamin in Reducing the severity of viral diseases of the respiratory tract.
