The aim of study is to analyze and compare the total antioxidant capacity of saliva between chronic periodontitis patients (at baseline and after therapy) and healthy non-chronic periodontitis patients (control group) in addition to comparing periodontal measurements such as gingival index, pocket depth and clinical attachment loss among chronic periodontitis patients at baseline and after one month from treatment.</p> <p><strong>Methods:</strong> The methodology of this study is a clinical quantitative study, which consists of A total of 53 patients who visited Duhok dental polyclinic/ Kurdistan region of Iraq from April 2021 to November 2021 were enrolled in this study. Among them, 37 patients suffered from chronic periodontitis, while 16 individuals were healthy and regarded as control group, age group was between 30 and 55 years old, out of 52 patients, 23 were female and 30 were male. Unstimulated saliva samples were collected from patients at baseline and one month after therapy (non-surgical treatment) and from control group. All samples were analyzed using total Antioxidant Capacity Assay Kit (Sigma-Aldrich, USA) by EPOCH2 plate reader (BioTek, USA).</p> <p><strong>Results:</strong> The means of periodontal parameters (Gingival Index, Periodontal Pocket Depth, Clinical Attachment Loss) in chronic periodontitis patients were significantly decreased after non-surgical treatment, while the Total Antioxidant Capacity (TAC) of saliva was significantly increased in chronic periodontitis patients after one month of treatment but still significantly lowered when compared with the control group.</p> <p><strong>Conclusions:</strong> The Total Antioxidant Capacity (TAC) of saliva decreased in chronic periodontitis patients as the result of oxidative stress generated by bacterial pathogens but elevated by non-surgical treatment and good oral hygiene home care.</p> NORA AKRAM HASAN; SAEED ALI MOHAMMED, ALI YAHYA SAEED ##submission.copyrightStatement## http://dmj.uod.ac/index.php/dmj/article/view/183 Tue, 03 Jan 2023 09:34:03 +0000 CLINICAL CHARACTERISTICS OF STROKE IN DUHOK PROVINCE http://dmj.uod.ac/index.php/dmj/article/view/184 <p><a href="https://doi.org/10.31386/dmj.2022.16.2.2"> https://doi.org/10.31386/dmj.2022.16.2.2</a></p> <p><strong>Background:</strong> Cerebrovascular accidents (stroke) are considered the second leading factor contributing to mortality and they are the third cause of disability. Stroke in low- and middle-income countries (LMIC) has doubled over the last four decades but little attention has been paid to this issue in this region.</p> <p><strong>Objectives:</strong> The distribution of stroke and its sub-type including pathologically ischemic (major vs. small vessel), intracerebral hemorrhage, subarachnoid hemorrhage and venous infarction and anatomically (anterior vs. posterior circulation), lobes localization were explored in this study.</p> <p><strong>Methods:</strong> In this large cross-sectional study, the patients who attended three general hospitals in Duhok governorate and were diagnosed with stroke and its types were included. The patients who attended the out-patient clinic of the hospitals were examined physically and clinically for the eligibility criteria.</p> <p><strong>Results:</strong> The mean age of the patients who were included in this study was 64.73 (SD: 12.55) ranged between 16 and 105 years. The mean BMI of the patients was 26.34 (SD: 3.90) with the dominant overweight population (40.8%) followed by normal weight (37.2%) and obese (21.4%). The study showed that most of the patients had hypertension (78.0%), dyslipidemia (63.1%) and sedentary lifestyle (52.9%). The prevalence of stroke subtypes was macrovascular stroke (48.7%), lacunar stroke (32.9%), ICH (15.7%), SAH (2.5%), and venous (0.2%). The prevalence of clinical risk factors was IHD (25.5%), past CVA (37.8%), and AF (25.4%). The study showed that patients with macrovascular and lacunar stroke were significantly older (65.80 and 65.84 years, respectively) compared to other stroke subtypes. The BMI of the patients with stroke subtypes was not significantly different, but the mean of all of them was overweight (P=0.453). The lowest rate of stroke subtypes was observed in patients with blood group O (P=0.969). The patients with T2DM (P&lt;0.001) and dyslipidemia (P=0.003), and those patients with sedentary lifestyles (P=0.034). The prevalence of stroke subtypes was significantly more prevalent in patients without IHD (P=0.046) and those without past CVA (P=0.017). The prevalence of stroke subtypes was not significant between those patients with and without AF (P=0.713).</p> <p><strong>Conclusions:</strong> The present study showed that macrovascular and lacunar strokes were the most prevalent types of stroke in this region. The stroke subtypes were more prevalent in patients with overweight, diabetes mellitus, and hypertension.</p> HEEWA ABDELSALAM YOUNIS ##submission.copyrightStatement## http://dmj.uod.ac/index.php/dmj/article/view/184 Tue, 03 Jan 2023 09:35:41 +0000 HEMATOLOGICAL PREDICTORS OF OUTCOME IN CHILDHOOD ACUTE LYMPHOBLASTIC LEUKEMIA IN DUHOK http://dmj.uod.ac/index.php/dmj/article/view/185 <p><a href="https://doi.org/10.31386/dmj.2022.16.2.3"> https://doi.org/10.31386/dmj.2022.16.2.3</a></p> <p>&nbsp;<strong>Background:</strong> While numerous studies have addressed the outcome of childhood acute lymphoblastic leukemia (ALL) in western developed countries, there is a scarcity of data in developing countries. This study explores the hematological predictors of outcomes in childhood acute lymphoblastic leukemia in Duhok city- Kurdistan Iraq.&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;</p> <p><strong>Method:</strong> the current study represents a cross-sectional study, conducted in Hivi Pediatric hospital and Zheen oncology center in Duhok, Iraq, and 116 patients were enrolled. The main features of childhood ALL, hematological predictors, type of therapy, and risk factors were analyzed to assess their effect on treatment outcome and survival rate.</p> <p><strong>Results:</strong>&nbsp; Median age of the study cohort was 5 years and the male-to-female ratio of 1.4:1. 87.9% of the cases were B-ALL while 12.1 were T-cell. Blood counts revealed a mean WBC count of 54.34 x 109/L, mean hemoglobin of 7.913 g/dl, and mean platelet count of 68.96 x 109/L. Complete remission (CR) rate was 92.2%, the overall 5-year survival (OS) was 76.7%, and relapse-free 5-year survival (RFS) was 73.3%. Patients with B-cell ALL had significantly higher OS compared to patients with T-cell (p value=0.01). Patients stratified into high-risk groups had significantly lower RFS and OS compared to the intermediate and standard risk groups (p value=0.04, 0.008 respectively). Patients aged &gt;10 years had significantly lower RFS (p value=0.001). Other factors such age&lt;1 year, PLT count, Hb count, and gender did not predict poor outcome</p> <p><strong>Conclusion:</strong> Immunophenotype, age&gt;10 years and risk stratification are important predictors of outcome in childhood ALL in our study, most notably, the patients’ survival rates were inferior to similar reports from western developed countries, The key areas for future work should include wider implementation of MRD and cytogenetic analysis in risk stratification to improve the outcome of childhood ALL.</p> KEVI JAFFER IBRAHIM; ADNAN ANWER AL-DOSKI, ABDULRAHMAN ABDULLAH MUHSIN ##submission.copyrightStatement## http://dmj.uod.ac/index.php/dmj/article/view/185 Tue, 03 Jan 2023 09:37:11 +0000 INTRA-OCULAR PRESSURE CHANGES FOLLOWING NEODYMIUM-DOPED YTTRIUM ALUMINIUM GARNET (ND:YAG) LASER CAPSULOTOMY http://dmj.uod.ac/index.php/dmj/article/view/186 <p><a href="https://doi.org/10.31386/dmj.2022.16.2.4"> https://doi.org/10.31386/dmj.2022.16.2.4</a></p> <p><strong>&nbsp;</strong></p> <p><strong>Background:</strong> Posterior capsule opacification (PCO) is common complication of cataract surgery, neodymium:yttrium aluminum-garnet (Nd:YAG) laser capsulotomy is standard treatment.
