Abstract The purpose of this study was to determine the levels of leptin, ghrelin, and nesfatin-1 to elucidate the causes of poor appetite and growth retardation in patients receiving methylphenidate therapy for attention deficit hyperactivity disorder. The study was performed on 89 male subjects; 48 patients and 41 healthy controls, aged 7–14 years. Following treatment, patients’ leptin levels increased and ghrelin levels decreased while no significant change was found in nesfatin-1 levels. Of the 48 patients, 34 developed lack of appetite. In patients who developed lack of appetite, body weight SDS, body mass index (BMI), and BMI SDS were statistically significantly reduced; moreover, height SDS was reduced, though not to a statistically significant extent. This study attempted to elucidate the mechanisms that mediate the association between methylphenidate and appetite and growth, for which no studies have yet to be published.

Neuroleptic malignant syndrome (NMS) is a life-threatening idiosyncratic reaction that usually occurs after the administration of antipsychotic drugs. Antidepressants, benzodiazepines, and antiepileptic drugs are also suggested to be associated with NMS. It is believed to result from a dopaminergic blockade in the central nervous system. NMS is manifested by hyperthermia, muscle rigidity, autonomic dysfunction, altered mental status, leukocytosis, and elevated serum creatinine phosphokinase. Valproate is commonly used in the treatment of many psychiatric and neurologic disorders. Valproate can precipitate NMS, especially when used with antipsychotic drugs concurrently. A 17-year-old male patient, who presented with fever, muscular rigidity, confusion, sweating, and tachycardia was admitted to the emergency room. He had been taking only valproate for the last two months for bipolar disorder. His laboratory analyses revealed raised serum hepatic enzymes, creatinine phosphokinase, and myoglobin levels. Considering fever, rigidity, autonomic dysfunction, cognitive alteration, and high creatinine phosphokinase levels, the patient was diagnosed with NMS. In this paper, we aim to discuss the association between valproate and NMS.

Our 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 5 mg 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.

Pisa syndrome, a rare dystonic reaction resulting from prolonged exposure to antipsychotic medications, is characterized by persistent dystonia of trunk muscles and abnormal posture. It is called Pisa syndrome, because the abnormal posture resembles the Leaning Tower of Pisa. Different from other types of dystonic reactions, Pisa syndrome is more prevalent in females and in older patients with organic brain changes. A 15-year-old male patient with mental retardation was admitted to pediatric neurology clinic for the complaint of abnormal posturing. He had been taking only risperidone for the last four years. Over the last month, the patient gradually developed tonic flexion of trunk and head toward left and was diagnosed with Pisa syndrome. In this paper, we aimed to discuss the association between risperidone use and Pisa syndrome in light of the available literature.

Obsessive compulsive disorder (OCD) is a chronic psychiatric disorder characterized by obsessions and compulsions. Early-onset OCD is one of the most common mental illnesses of children and adolescents, with a prevalence of 1% to 3%. It is related to worse lifespan symptoms and prognosis. Therefore, the treatment of OCD in children and adolescent has gained importance. If it is not treated successfully, the compulsive behaviors may cause extreme stress for children and their parents. Although minor complications of OCD are commonly observed, major complications are considerably rare due to the nature of compulsive behaviors. Apparently, loss of vision, autocastration, rectal prolapse are examples of major complications secondary to OCD. As far as we know, it is the first case of tibia stress fracture secondary to OCD. In the present case report, we will discuss tibia stress fracture developing secondary to compulsive behavior due to OCD.

Meltem Çobanoğulları Direk; Veli Yıldırım; Serkan Güneş; Gulcin Bozlu; Cetin Okuyaz

Serotonin syndrome (SS) is a potentially life-threatening condition associated with increased serotonergic activity in central nervous system and may occur during the use of serotonergic drugs. Although increasing frequency of serotonergic drug use in children, pediatricians, emergency medicine and pediatric intensive care specialists have not enough knowledge and experience about SS that is a potentially life-threatening condition. A 12-year-old girl patient was admitted to our emergency room with the history of involuntary contractions on her extremities and alteration of consciousness. Her physical examination showed agitation, hyperthermia, dilated pupils, tremor, increased deep tendon reflexes, positive spontaneous clonus, agitation, flushed skin and diaphoresis, excessive perspiration, and continuous horizontal ocular movements. The patient diagnosed as SS by clinical history, physical and laboratory findings. In this paper, we will discuss SS occurred in a 12-year-old girl after concurrent clomipramine and risperidone use.

Risperidone Related Raynaud’s Phenomenon: An Adolescent Case

Serkan Güneş; Ozalp Ekinci; Halenur Teke; Veli Yıldırım

Raynaud’s phenomenon is a recurrent vasospastic condition with reducing in peripheral blood flow due to cold, or emotional stress. White, blue and red discolorations occur during the attacks. Serotonin reuptake inhibitors, psychostimulants, and aripiprazole are reported to be related with Raynaud’s phenomenon. Risperidone is an atypical antipsychotic drug with dopaminergic and serotonergic effects. In children and adolescents, risperidone is used for bipolar disorder, tic disorders, conduct disorder, schizophrenia, symptoms of irritability and self-mutilation. Here we report a case of Raynaud’s phenomenon associated with risperidone in a 12-year-old boy. Raynaud’s phenomenon occurred two weeks after starting risperidone and disappeared after stopping risperidone.

Introduction  There has been a sudden idiopathic hearing loss case presented after methylphenidate treatment in a child with attention deficit hyperactivity disorder (ADHD). Objective  This study was performed to reveal the probable ototoxic side effects of methylphenidate use in patients with ADHD. Methods  Thirty pediatric patients with ADHD were included in the study. Pure tone audiometry, speech discrimination scores, waves I, III, V absolute latencies and waves I-III, I-V, III-V interpeak latencies at the 80 dB nHL intensity after click stimulus auditory brainstem response (ABR) results were compared before and 3 months after methylphenidate treatment. Results  There were no statistically significant difference between pretreatment and posttreatment pure tone and speech audiometry findings and ABR results (p > 0.05 for all parameters). Conclusion  Methylphenidate can be regarded as a safe drug regarding ototoxic side effects. Additional studies with a larger sample size and longer follow-up may be needed.

Serkan Güneş; Veli Yıldırım; Ozalp Ekinci; Fevziye Toros

Incest is defined as sexual relations between close blood relatives. Many psychiatric disorders may occur after incest in children, but sleepwalking due to sexual abuse is a rare condition. Sleepwalking, a type of parasomnias, is characterized by sudden motor movements that occur during the first third of the night. Sleepwalkers may get up and walk around during sleep and they cannot usually remember the episodes in the morning. In this paper, an eight-year-old girl developed sleepwalking after being sexually abused by her father has been discussed.
