Hiccup is a sudden-onset repeated involuntary and spasmodic contraction of the diaphragm and intercostal muscle accompanied by laryngeal closure, generating the characteristic inspiratory sound and discomfort. Various factors including drugs may trigger the hiccups. There are some reports regarding the possible links between psychotropic agents that can affect the dopaminergic system and the triggering of hiccup; however, to our knowledge, there are no data regarding sertraline-induced hiccup. We present the case of a boy with obsessive-compulsive disorder and attention-deficit/hyperactivity disorder who displayed hiccup after sertraline therapy...

INTRODUCTION: Impaired nocturnal sleep and excessive daytime sleepiness are common problems for patients with Parkinson's disease, and patients with Parkinson's disease with sleep dysfunction are 5 times more likely to experience psychotic symptoms. Pimavanserin, a 5-HT2A inverse agonist approved to treat Parkinson's disease psychosis, may improve sleep quality in patients with Parkinson's disease experiencing sleep disturbances. METHODS: Scales for Outcomes in Parkinson's Disease nighttime sleep (SCOPA-NS) and SCOPA-daytime sleepiness (DS) data obtained during 2 double-blind placebo-controlled studies of pimavanserin in persons with Parkinson's disease psychosis were evaluated...

Urinary retention is a well-documented adverse effect of antipsychotic medications and is thought to be mediated by anticholinergic, adrenergic, and other neurotransmitter effects. Whereas urinary retention has been reported with typical and some atypical antipsychotics, there have been no reports of urinary retention with the novel antipsychotic cariprazine. We report on a case of urinary retention associated with cariprazine. Possible mechanisms for this adverse effect are discussed.

OBJECTIVES: The choice of antiepileptic drug is typically based on seizure type, and there is no evidence for superior effectiveness or potential deterioration of particular antiepileptic drug in specific etiologic subgroups. The aim of the study was to identify etiological factor(s) associated with increased risk of seizure aggravation with levetiracetam (LEV). METHODS: A retrospective analysis of 139 patients treated with LEV was performed. Seizure aggravation was defined as a 100% or greater increase in seizures frequency, which occurred within 1 month of drug introduction...

BACKGROUND: Natalizumab is the first targeted humanized monoclonal antibody to be approved for the treatment of relapsing-remitting multiple sclerosis (RRMS). Natalizumab appears to be more effective than current first-line disease-modifying therapies. In our study, we aimed to evaluate the outcome of Saudi patients with active RRMS treated with natalizumab and compare the results with other outcomes in the Gulf and international trials. METHODS: We conducted a retrospective single-center observational study involving 32 patients with RRMS at King Abdulaziz Medical City in Jeddah, Saudi Arabia...

BACKGROUND: Rhabdomyolysis involves the release of intracellular contents secondary to muscle cell injury; it generally presents with muscle pain and weakness. Although several psychotropic agents have been documented as causes of rhabdomyolysis, there are no reports of tandospirone-induced rhabdomyolysis. CASE: We present the case of a 15-year-old Japanese girl who had posttraumatic stress disorder after the Great East Japan Earthquake. She received a dose of 60 mg of tandospirone while taking 10 mg of tandospirone and 400 mg of valproic acid every day...

Musical hallucinations (MHs) are relatively uncommon phenomena sometimes encountered in older patients, especially older women. They usually involve popular, overlearned music, either entire songs or repetitive snippets. While MHs are most commonly associated with hearing loss, they may occur in a variety of psychiatric, neurologic, and iatrogenic conditions. We report a 91-year-old man whose MHs were causally related to the antidepressant mirtazapine. Although mirtazapine is generally well tolerated, it may rarely cause MHs or other psychotic symptoms...

AIM: Up to 60% of depressed patients do not obtain sufficient relief from a course of antidepressant therapy, and these treatment-resistant major depressive disorder (TRD) patients are at increased risk for relapse, chronicity, persistent psychosocial impairments, and suicide. Probiotics actively participate in treatment of neuropsychiatric disorders. However, the role of gut microbiota in brain disorders and depression remains unclear. We performed a prospective study to evaluate the effects of Clostridium butyricum MIYAIRI 588 (CBM588)...
