The Use of Psilocybin in the Treatment of Psychiatric Disorders with Attention to Relative Safety Profile: A Systematic Review.

There has been a reemergence of research into the use of substances such as LSD, MDMA, and psilocybin for the treatment of psychiatric disorders. This increase in consideration toward the medicinal use of these compounds has been termed the "Psychedelic Renaissance." This article specifically explores the background of psilocybin, a psychoactive compound that is naturally derived from certain species of fungi. Pubmed was searched by one doctoral-level researcher using specific Boolean operator terms. The results were filtered by title and abstract and 76 articles were screened and analyzed in full detail. Oral psilocybin is showing itself to be clinically efficacious by producing statistically significant reductions in depression and anxiety symptoms over time versus control in multiple clinical trials. It has also been shown to reduce cigarettes per day and drinks per day in patients with substance use disorders. Thus far, there have been no significant adverse clinical events from psilocybin and there also have been no verifiable recorded deaths reported. Larger studies need to be performed before the drug can potentially become approved for use in the general population.

Initiating Psychotropic Treatment in a Patient With Alpha-Gal Syndrome.

Alpha-gal syndrome, which is typically acquired by a tick bite, is an IgE-mediated immune response to galactose-alpha-1,3-galactose (alpha-gal), an oligosaccharide in most mammalian tissue. This report describes a 29-year-old Caucasian female with comorbid alpha-gal syndrome who presented to the inpatient psychiatric unit after an intentional overdose. Because of the patient's alpha-gal syndrome, the treatment team worked with the hospital pharmacy to evaluate treatment options that did not contain mammalian products. After carefully reviewing the ingredients of suitable medications on formulary, the patient was started on a generic sertraline formulation that was free of mammalian derivatives. At the time of discharge, the patient reported significant symptom improvement and was free of symptoms suggesting an alpha-gal allergic reaction. This case illustrates the challenges of starting psychiatric medications in a patient with comorbid alpha-gal syndrome.

Management of Attention Deficits and Behavioral Dyscontrol With an Evening-Dosed Methylphenidate Formulation in Smith-Magenis Syndrome.

Smith-Magenis syndrome (SMS) is a severe neurodevelopmental disorder characterized by intellectual disability, sleep abnormalities, behavioral dyscontrol, and a distinct somatic phenotype. This report describes the case of a 10-year-old female with SMS who presented with aggression, self-injurious behavior, impulsivity, and attention deficits. She had failed trials of several stimulants and clonidine prior to presentation. An evening-dosed, delayed-release/extended-release methylphenidate formulation was added to her regimen, and she demonstrated significant improvement in her presenting symptoms. To our knowledge, this is the first published case of the use of an evening-dosed, delayed-release/extended-release methylphenidate formulation in a patient with SMS. This case highlights the need for further research on the role of these medications in managing behavioral and attentional symptoms associated with SMS.

Denial of Pregnancy in a Patient With a History of Pseudocyesis.

Denial of pregnancy is a condition in which a pregnant patient does not believe she is pregnant. This case describes a 23-year-old Caucasian female, with a past psychiatric history of pseudocyesis, stimulant use disorder, and schizophrenia, who was admitted to the inpatient psychiatric unit for the treatment of psychosis, suicidal thoughts, and homicidal ideation. During her hospitalization, an intrauterine pregnancy was confirmed with three serum quantitative human chorionic gonadotropin (hCG) levels and a transabdominal ultrasound. Despite definitive evidence of pregnancy, the patient reported it was impossible she was pregnant and stated she had not had intercourse for more than a year. The patient was treated with IM haloperidol decanoate and PO haloperidol. Care was coordinated with the obstetrics team to ensure the patient and her fetus received adequate prenatal care. After acute stabilization, the patient was discharged with close follow-up. This case presentation describes one of the few documented cases of pregnancy denial in a patient with a history of pseudocyesis. Additionally, this case highlights the ethical issues associated with the treatment of pregnancy denial patients. Additional studies are necessary to fill in the gaps in the literature on this unique condition.

The anti-asthmatic drug pranlukast suppresses the delayed-phase vomiting and reverses intracellular indices of emesis evoked by cisplatin in the least shrew (Cryptotis parva).

The introduction of second generation serotonin 5-HT3 receptor (5-HT3) antagonist palonosetron combined with long-acting substance P neurokinin NK1 receptor (NK1) antagonists (e.g. netupitant) has substantially improved antiemetic therapy against early- and delayed-phases of emesis caused by highly emetogenic chemotherapeutics such as cisplatin. However, the improved efficacy comes at a cost that many patients cannot afford. We introduce a new class of antiemetic, the antiasthmatic leukotriene CysLT1 receptor antagonist pranlukast for the suppression of cisplatin-evoked vomiting. Pranlukast (10mg/kg) by itself significantly reduced the mean frequency of vomits (70%) and fully protected least shrews from vomiting (46%) during the delayed-phase of cisplatin (10mg/kg)-evoked vomiting. Although, pranlukast tended to substantially reduce both the mean frequency of vomits and the number of shrews vomiting during the early-phase, these reductions failed to attain significance. When combined with a first (tropisetron)- or a second (palonosetron)-generation 5-HT3 receptor antagonist, pranlukast potentiated their antiemetic efficacy during both phases of vomiting. In addition, pranlukast by itself prevented several intracellular signal markers of cisplatin-evoked delayed-vomiting such as phosphorylation of ERK1/2 and PKA. When pranlukast was combined with either palonosetron or tropisetron, these combinations suppressed the evoked phosphorylation of: i) ERK1/2 during both acute- and delayed-phase, ii) PKCα/ß at the peak acute-phase, and iii) PKA at the peak delayed-phase. The current and our published findings suggest that overall behavioral and intracellular signaling effects of pranlukast via blockade of CysLT1 receptors generally appear to be similar to the NK1 receptor antagonist netupitant with some differences.
