This study aimed to evaluate the psychometric characteristics of the Turkish version of the CAS in a Turkish psychiatric outpatient setting. A total of 198 patients with a preexisting psychiatric disorder completed the CAS scale. The scale's validity and reliability were evaluated using convergent and concurrent validity, internal consistency, exploratory and confirmatory factor analyses, and ROC analysis. The Turkish version of CAS might help physicians assess the COVID-19 associated anxiety in patients with psychiatric comorbidities.

Objective:Revealing of unknown adverse effects of atypical antipsychotics on pediatric population may take a long period of time. The purpose of this prospective study is to document changes in the liver function tests (LFTs) associated with Risperidone usage in a group of children and adolescents.Method:Study subjects consist of 120 youths with ages ranging from 3-17 years. For this study, patients' baseline and follow-up weight and liver function tests (LFT) including alanine aminotransferases(ALT) and aspartat aminotransferases (AST), gamma gluatamyl transerase (GGT), alkaline phosphatase (ALP) and serum bilirubin levels were measured before and after the treatment period of one month.Results:Only one eight years old male patient's ALT levels increased up to three-fold and AST levels increased up to two-fold of the basal levels. First month mean levels of liver enzymes and billuribin of the patients were significantly higher than the baseline. One or more of the liver enzymes and/or billuribin levels of sixty-three patients (52,5%) showed an asymptomatic increase in the first month of this study. Weight gain was observed in 58 patients (57.4%). There was no significant association between changes in weight and liver enzymes and billuribin levels.Conclusion:We found asymptomatic LFT abnormalities mostly in the form of ALP elevation in 52.5% and marked liver enzymes elevation in 0.8% of risperidone treated subjects. These findings suggest that risperidone treatment in the short term commonly leads to liver function changes however it rarely may induce a serious hepatic toxicity at therapeutic doses in children and adolescents.

Amaç: Lityum duygudurum bozukluklarının koruma tedavisinde etkili bir ilaç olarak tüm dünyada tanınmaktadır. Lityumun bipolar bozukluk profilaksisindeki etkinliği yetmişli yılların başından beri kanıtlanmıştır. Lityum bipolar bozuklukta akut duygudurum epizodları farmakoterapisi, döngülerin önlenmesi, önleyici tedavi ve intiharın önlenmesinde dayanak noktası olmuş ve olmaya devam etmektedir. Bazı ülkelerde lityum düzeylerinin mevsimsel değişiklikleri olduğu şeklinde yayınlar mevcuttur. Winter sale on lithium levels: the impact of seasonality Objective: Lithium is recognized worldwide as an effective prophylactic agent in mood disorders. Prophylactic efficacy of lithium in mood disorders has been established since the early seventies. Lithium has been and continues to be the mainstay of bipolar disorder (BD) pharmacotherapy for acute mood episodes, switch prevention, and suicide prevention. There are reports of seasonal variation in lithium levels from a few countries. Variability in the lithium level can lead to a lack of efficacy or to toxicity, making seasonal variation clinically relevant. We aimed to compare lithium levels of bipolar patients between summer and winter. Methods: Euthymic bipolar patients who were followed in the Raşit Tahsin Mood Clinic of the Bakırköy Research and Training Hospital for Psychiatry, Neurology and Neurosurgery were recruited for the study, and lithium levels were measured in the second part of winter and summer (15 th of June to 1st of September and 15 th of January to 1 st of March). A prospective case sheet audit was performed for 32 BD patients for recording plasma lithium level, age and gender for one year. Bipolar patients whose treatment dosage of lithium was changed for any reason during the study follow-up were excluded. Situations of lithium use other than for bipolar disorder were excluded. The presence of concomitant diagnoses of mental retardation or drug dependence constituted exclusion criteria, as did medication non-compliance detected by persistently low lithium plasma levels. The use of antihypertensive drugs, nonsteroidal anti-inflammatory drugs, theophylline, some antibiotics, topiramate, and diuretics that could cause an increase in plasma concentrations of lithium, and of theophylline that could reduce lithium concentrations constituted exclusion criteria. Sodium levels were also monitored due to their propable effect on lithium levels. Lithium levels were compared using the paired sample t-test. Correlation analysis was done for the parameters that could affect lithium levels. Results: The mean age of the patients was 35.75±9.59 years, the mean age of onset was 21.97±6.17 and the mean duration of disorder was 13.90±9.41 year. 15 out of 32 patients were male. The overall average dose of lithium taken by the patients was 1190.6±249.0 mg/day. The mean lithium plasma level was 0.75±0.12 mEq/L in winter, and the mean lithium plasma level was 0.83±0.12 mEq/L in summer (p=0.003). The overall serum sodium levels were 139.1±2.2 mEq/L in summer and 137.1±2.3 mEq/L i...
