Item Dystonia in an Adolescent on Risperidone Following the Discontinuation of Methylphenidate: A Case Report(2015) Guler, Gulen; Yildirim, Veli; Kutuk, Meryem Ozlem; Toros, Fevziye; 25912546Attention-deficit/hyperactivity disorder (ADHD) is a neurodevelopmental disorder with common comorbidities that include oppositional defiant disorder, conduct disorder, anxiety disorder, and affective disorders. Because of these comorbidities, drug combination treatments and drug drug interactions are becoming increasingly more frequent. The present case report describes an acute dystonic reaction following the abrupt discontinuation of methylphenidate from a drug regimen with risperidone. The patient experienced acute dystonic reactions on three separate occasions when he forgot to take his methylphenidate medication. The present report informs clinicians about the possible side effects, such as dystonia, when psychostimulant and antipsychotic drug combinations are altered and suggests that the abrupt cessation of stimulants may lead to the development of movement disorders, Therefore, appropriate care is necessary when changing the dose of a drug or abruptly discontinuing a drug from a combination of psychostimulants and antipsychotics.Item Persistent hiccups due to aripiprazole in an adolescent with obsessive compulsive disorder responding to dose reduction and rechallenge(2016) Kutuk, Meryem Ozlem; Tufan, Ali Evren; Guler, Gulen; Yildirim, Veli; Toros, Fevziye; 27099770Our case involves persistent hiccup arising in an adolescent with obsessive compulsive disorder (OCD) who was using aripiprazole as an augmentation to fluoxetine and whose hiccups remitted with dose reduction and rechallenge. Treatment suggested that aripiprazole might lead to hiccups. Antipsychotics are also used for the treatment of hiccups, but recent case reports suggest that they cause hiccups as well. Within 12 h of taking 5mg aripiprazole, the 13-year-old girl began having continuous hiccups, which lasted for 3-4 h. The hiccups resolved when the dose of aripiprazole was reduced to 2.5 mg. To achieve augmentation, aripiprazole was replaced with risperidone 0.5 mg/day for 1 month, but excess sedation was observed. As a result, aripiprazole was restarted at a dose of 2.5 mg/ day, and 1 week later, it was increased to 5 mg/every other day. No hiccups were observed.Item Achalasia as a complication of bulimia nervosa: A case report(2017) Kutuk, Meryem Ozlem; Guler, Gulen; Tufan, Ali Evren; Toros, Fevziye; Kaytanli, Umut; 0000-0002-2918-7871; 30263180; AAI-9626-2021Objective: Oesophageal achalasia is a medical condition characterised by oesophageal aperistalsis, an increased resting pressure with partial or incomplete relaxation of the lower oesophageal sphincter. Bulimia nervosa (BN) is an eating disorder manifested by binge eating attacks followed by recurrent inappropriate compensatory behaviours, such as self-induced vomiting and excessive exercise. Dysphagia, regurgitation, vomiting, retrosternal pain, heartburn, weight loss, avoidance of eating, consumption of large amount of liquids and aberrant eating behaviours are symptoms of both achalasia and BN. Owing to these common signs and symptoms, oesophageal achalasia can be misdiagnosed as an eating disorder. In addition, oesophageal achalasia can occur as a complication of BN. It is often difficult to distinguish organic and psychological vomiting or comorbidity because of overlapping of the symptoms. Case report: We report the case of a patient who developed oesophageal achalasia following severe, repetitive vomiting as a complication of BN. Conclusion: We want to raise awareness regarding the development of a medical illness in the presence of a psychiatric disorder. Importantly, physicians should have a fundamental knowledge of these two diseases regarding their clinical patterns to differentially diagnose one or both disorders as quickly as possible.Item No Association between Polymorphisms of Vitamin D and Oxytocin Receptor Genes and Autistic Spectrum Disorder in a Sample of Turkish Children(2018) Kutuk, Meryem Ozlem; Bozdogan, Sevcan Tug; Tufan, Evren; Altintas, Zuhal; Temel, Gulhan Orekici; Toros, Fevziye; 30466214Objective: Autism spectrum disorder (ASD) is a neurodevelopmental disorder characterized by impairment in social skills and communication with repetitive behaviors. Etiology is still unclear although it is thought to develop with interaction of genes and environmental factors. Oxytocin has extensive effects on intrauterine brain development. Vitamin D, affects neural development and differentiation and contributes to the regulation of around 900 genes including oxytocin receptor gene. In the present study, the contribution of D vitamin receptor and oxytocin receptor gene polymorphisms in the development of ASD in Turkish community was investigated. To our knowledge, this is the first study examining these two associated genes together in the literature. Methods: Eighty-five patients diagnosed with ASD according to DSM-5 who were referred to outpatient clinics of Child and Adolescent Psychiatry of Baskent University and Mersin University and 52 healthy, age and gender-matched controls were included in the present study. Vitamin D receptor gene rs731236 (Taq1), rs2228570 (Fok1), rs1544410 (Bsm1), rs7975232 (Apa1) polymorphisms and oxytocin receptor gene rs1042778 and rs2268493 polymorphisms were investigated using real time polymerase chain reaction method. Results: No significant difference between groups in terms of distribution of genotype and alleles in each of polymorphisms for these genes could be found. Conclusion: Knowledge of genes and polymorphisms associated with the development of ASD may be beneficial for early diagnosis and future treatment. Further studies with larger populations are required to demonstrate molecular pathways which may play part in the development of ASD in Turkey.
