(Muş Alparslan Üniversitesi, 2023) Dicle, Yalçın; Dicle, Yalçın; Pamuk, Deniz; Yalçın; Department of Basic Medical Sciences / Temel Tıp Bilimleri Bölümü
Abstract: Objective: Because the number of aging population is rising gradually this descriptive study is to evaluate the behaviors of individuals’ hygiene residing in residential homes during COVID-19 Pandemic. Method: The study was conducted through face-to-face interviews with 100 elderly individuals residing in nursing homes in two cities within the borders of the Eastern Anatolia Region, one of which has normal and the other metropolitan status. Data were collected with a socio-demographic information questionnaire and a questionnaire examining behaviors related to the mask-distance-cleanliness triad to protect against disease. Pearson chi-square analysis was applied to express the relationship between the groups. Results: A statistically significant relationship was found between the variable of the participants' COVID-19 recovery status and the use of masks indoors. (p: 0,008; r= .514) It was determined that there was a statistically significant relationship between the variable of COVID-19 transmission status of residential home residents and the use of hand sanitizer also there was a statistically significant relationship between the variable of the participants' status of having COVID-19 and the frequency of visitors to their rooms (p: 0,001; r= .646). Conclusions: Although the hygiene behaviors gained in order to prevent and reduce transmission during the pandemic are approaching the ideal level, it has been understood that more attention should be paid to the use of masks and social distance.
Detection of Human Brucellosis by Brucellacapt and Rose Bengal Test in the Endemic Area
(Fazile Nur Ekinci Akdemir, 2023) Dicle, Yalçın; Dicle, Yalçın; Kaçtaş, Şerif; Gümüş, Ali Furkan; Department of Basic Medical Sciences / Temel Tıp Bilimleri Bölümü
Abstract: Although brucellosis is the most common zoonosis in the world, it remains an infectious disease that has not received sufficient attention. There are a few tests detecting brucellosis by serum. Rose Bengal Test is an advantageous one. Our aim with this study was to compare Rose Bengal and Brucellacapt tests in serum samples and draw attention to the advantages of the test. Between June 2019 and June 2021, 7827 serum samples sent to the public health laboratory with a provisional diagnosis of brucellosis were evaluated. The Rose Bengal and Brucellacapt test (Vircell, Spain) was used to diagnose infection. Samples with antibody titer ≥1/160 were considered positive. Of the 7827 samples included in the study, 354 (4.6%) of the total 7677 serum samples tested were RBT positive, 118 (3.1%) of the 3776 samples tested were BCAP positive, and 118 (3.3%) of the 3626 samples tested were both RBT and BCAP positive. It was found that seropositivity was significantly higher in female patients (p<0.10). RBT and BCAP test positivity were most frequently observed in the 25-34 year age group. Considering brucellosis cases in terms of seasonal changes; 10.7% of cases were found in spring, 52.4% in summer, 20.9% in fall, and 16% in winter. In suspected cases, RBT is still considered the ideal detection method because it is easy to use, inexpensive, sensitive, and provides rapid results. It was concluded that the BCAP test is suitable for diagnosis due to its ability to detect blocker and high titer antibodies.
Retrospective Evaluation of Tularemia Cases in Muş Province: 2011-2022
(Mardin Artuklu University, 2023) Dicle, Yalçın; Aydın, Elif; Şen Gündoğan, Nesibe Efruz; Yalçın; Department of Basic Medical Sciences / Temel Tıp Bilimleri Bölümü
Objective: Tularemia is a bacterial disease of humans, wild and domestic animals. Recently, an increase in human tularemia cases has been observed in many countries worldwide. This study aimed to calculate the incidence of tularemia cases in Muş, determine the seasonal distribution of cases, and describe the socio demographic and clinical characteristics of tularemia cases detected over a twelve-year period. Methods: Data from 162 patients diagnosed clinically and serologically with tularemia and admitted to health facilities in Muş province between 2011 and 2022 were retrospectively analysed. Results: In our study, among 162 tularemia patients with F. tularensis microagglutination test titres of 1/160 and above, the ratio of male and female cases was equal (50%), and the mean age was 24.51 years. In the twelve-year evaluation, there were two major epidemics, and the most cases were seen in 2018 with 37 cases. Most cases were observed in winter (38.3%) and autumn (25.3%). Oropharyngeal tularemia was the most common form (64.2%) among the cases evaluated. Similar disease was found in 33.3% of patients living in the same neighbourhood as the patients, and no mortality was observed in any of the patients. Conclusion: As the oropharyngeal form is the most common, contact with contaminated water should be questioned, rodent and tick populations should be monitored and detailed epidemiological studies should be conducted. We believe that hygiene and sanitation measures are important with regard to tularemia outbreaks.
A Study on The Presence of Legionella pneumophila in Hospital Water Samples from Eastern Turkey
(Dicle Üniversitesi Tıp Fakültesi, 2023) Dicle, Yalçın; Dicle, Yalçın; Tuna, Duygu Kübra; Department of Basic Medical Sciences / Temel Tıp Bilimleri Bölümü
Objective: Legionnaires' disease is a fatal form of pneumonia brought on by an infection mostly caused by the 60 different species of Legionella pneumophila. Legionnaires' illness is caused by Legionella spp.-contaminated water systems. In this work, we sought to analyze Legionella species, serogroups (SG), and contamination in the water sources of hospitals in five regions in eastern Turkey. Methods: Between January 2017 and December 2018, a total of 1008 samples were examined, including 2 cooling towers, 62 hot water tanks, 104 cold water tanks, and 840 faucet shower heads. Samples were collected by the standard culture method L. pneumophila SG 1, it was analyzed for L. pneumophila SG 2-16 and Legionella spp. The samples were inoculated into BCYE and GVPC medium, and the colonies were assessed using a latex agglutination test, followed by species- and serotype-level identifications. Results: In our study, a total of 1008 water samples were examined, of which 35.31% (356) belonged to 2017, while 64.68% (652) belonged to 2018. 83.33% of the water samples were taken from faucets and shower heads, 10.32% from the cold water tank, 6.15% from the hot water tank, and 0.2% from the cooling tower, and the highest positivity rate was observed in the hot water tank with 12.60%. 7.04% (71) of the samples were positive, and 16.9% (12) of the positive samples were L. pneumophila SG 1, 77.46% (55) L. pneumophila SG 2-14 was detected, while 5.63% (4) were nonpneumophila (Legionella spp) it has been determined as. Conclusions: Legionella disease remains a significant public health threat. The water tanks of hospitals and hotels should be investigated more thoroughly, the necessary disinfection procedures should be carried out frequently. All hospitals should have water management policies, and towns and large buildings should establish comprehensive water system management programs that decrease Legionella growth and transmission. To enhance prevention measures and clinical diagnosis, we also need quicker ways of detecting Legionella in water systems and clinical samples.
