Objective Bipolar disorder (BD) is a chronic mood disorder characterized by recurrent episodes that has a lifetime prevalence of 0.4– 5.5%. The neurochemical mechanism of BD is not fully understood. Oxidative stress in neurons causes lipid peroxidation in proteins associated with neuronal membranes and intracellular enzymes and it may lead to dysfunction in neurotransmitter reuptake and enzyme activities. These pathological processes are thought to occur in brain regions associated with affective functions and emotions in BD. The relationship between the number of manic episodes and total oxidant-antioxidant capacity was investigated in this study. Methods Eighty-two BD patients hospitalized due to manic symptoms and with no episodes of depression were enrolled in the study. Thirty of the 82 patients had had their first episode of mania, and the other 52 patients had had two or more manic episodes. The control group included 45 socio-demographically matched healthy individuals. Serum total antioxidant capacity (TAC) and total oxidant capacity (TOC) measurements of the participants were performed. The oxidative stress index (OSI) was calculated by TOC/TAC. Results There were no significant differences in OSI scores between BD patients with first-episode mania and BD patients with more than one manic episode. However, OSI scores in both groups were significantly higher than in the control group. TOC levels of BD patients with first-episode mania were found to be significantly higher than TOC levels of BD patients with more than one manic episode and healthy controls. There were no significant differences in TAC levels between BD patients with first-episode mania and BD patients with more than one manic episode. TAC levels in both groups were significantly higher than in the control group. Conclusion Significant changes in oxidative stress indicators were observed in this study, confirming previous studies. Increased levels of oxidants were shown with increased disease severity rather than with the number of manic episodes. Systematic studies, including of each period of the disorder, are needed for using the findings indicating deterioration of oxidative parameters.

Objective Previous studies have shown that there is a correlation between lipid levels and depressive mood, and that lipids could be useful biomarkers for depression. We conducted this study to clarify the association between lipid levels and depressive mood in adolescents, especially in community samples. Methods We analyzed data from the Korea National Health and Nutrition Examination Survey (KNHANES) that was conducted from 2013 to 2016. A total of 2,454 adolescents aged 12–18 years (1,273 boys, 1,181 girls) participated in the Survey. We conducted a cross-sectional study using multiple logistic regression, adjusting for age, household income, daily energy intake, daily fat intake, and daily cholesterol intake, to assess the association between depressive mood and serum lipid levels. Results Depressive mood was found in 8.7% of those included in the study. Borderline (110–129 mg/dL) and high (≥130 mg/dL) levels of low-density lipoprotein cholesterol (LDL-C) were significantly associated with depressive mood [Borderline level: odds ratio (OR)=5.55, 95% confidence interval (CI) 1.56–19.81, p=0.01; High level: OR=5.73, 95% CI 1.06–31.08, p=0.04]. However, this association was not found in girls. Conclusion Our findings indicate that depressive mood in boys is associated with higher LDL-C levels. Further investigation regarding this relationship and the underlying biological mechanisms is needed.

Objective: Little is known about the effects of psychodrama group therapy on the level of stress, anxiety and depression of the group members, and the biological markers of stress. The aim of this study test cortisol level as a biological reflection of some mental characteristics gained by the psychodrama method in coping with stress. Methods: Depressive patients aged between 18 and 65 years, who diagnosed with depression according to DSM-5, without psychiatric comorbidity, who do not use drugs and were available for psychodrama were enrolled into the study. These patients were evaluated using the Perceived Stress Scale, State-Trait Anxiety Inventory and Beck Depression Inventory. In order to observe the circadian rhythm of cortisol, samples were collected from the participants before lunch, before dinner and before going to sleep on the day before psychodrama and on the 0, 15th, and 30th minutes after awakening in the morning of the psychodrama day; as well as just before and after the psychodrama session. Saliva cortisol level just before the initial session of psychodrama group therapy was compared with the saliva cortisol level just after the last psychodrama session at the end of 16 weeks. Results: Statistically significant difference was determined between the scores of perceived stress scale, STAI-1, STAI-2, beck depression inventory and salivary cortisol level before and after psychodrama session. There was significant decrease in both the scale scores and salivary cortisol after vs. before psychodrama. Conclusion: This results is important as it shows the biological aspect of clinical improvement. Further studies would provide us with better understanding of the effects of psychodrama group psychotherapy on depressive mood and biological projections by means of short-term and long-term follow-up studies.

Benign cementoblastoma of the anterior mandible: an unusual case report
Armağ,an Ç,alış,kan,Tuğ,ç,e Berre Karö,z,Mahmut Sumer,Aydan Aç,ıkgö,z,Yurdanur Sü,llü 대한구강악안면외과학회 2016 대한구강악안면외과학회지 Vol.42 No.4
A benign cementoblastoma, which is another name for a true cementoma, is a rare neoplasm that develops from odontogenic ectomesenchyme. It is characterized by a mineralized mass attached to the apex of the root produced by neoplastic cementoblasts. More than 75% of cases arise in the mandible, with 90% of them manifesting in the molar and premolar regions. This neoplasm occurs most commonly in children and young adults, with males being affected slightly more than females. Radiographically, the tumor is observed as a well-defined radiopaque mass that is fused to a tooth root and is surrounded by a radiolucent rim. The treatment of benign cementoblastoma consists of removal of the lesion and extraction of the affected tooth. This report presents an unusual case of benign cementoblastoma in a 31-year-old female, presenting as a densely mineralized mass seen at the apex of the impacted right mandibular canine tooth on radiographs.
