Characterization of Bipolar Disorder in Anton Chekhov's The Black Monk.

Anton Chekhov (1860-1904) was a famous Russian author and physician known for his dramas and short stories. Many of his works also address mental health problems. Here, the present paper is investigating his novella The Black Monk that was published in 1894. Its main protagonist, Kovrin, likely suffered from bipolar disorder as he exhibited elevated mood, grandiosity, lack of sleep, and delusions. His symptoms are analyzed based on current DSM-5 criteria, and he appears to meet diagnostic criteria for bipolar I disorder. Chekhov himself suffered from a mood disorder, but we speculate that he himself exhibited some bipolar symptoms. Those were likely an inspiration for when he wrote The Black Monk.

Clinical Experience With Intramuscular Clozapine.

Clozapine is the most effective antipsychotic for patients with treatment-refractory schizophrenia, but many refuse to accept oral clozapine therapy. Intramuscular (IM) clozapine represents a convenient alternative for their treatment. The aim of this review is to summarize studies investigating IM clozapine administration. When initially developed, clozapine was also provided as an IM formulation, but the manufacturer later discontinued its production. Recently, IM clozapine became again available as an unlicensed product distributed by the Dutch company Apotheek A15. The use of IM clozapine has been reported in older studies on clozapine's adverse effects. It has also been described in detail in 5 more recent and generally smaller (n = 7 - 59) retrospective studies in patients refusing to take oral clozapine. In addition, its administration has been noted in 5 case reports. IM clozapine has been used at approximately ½ of the dose of oral clozapine due to pharmacokinetic considerations. It has been used in doses of up to 500 mg per day and for up to 99 days of treatment. The majority of patients (between 60 and 100%) were successfully transitioned to oral clozapine within a few days of IM treatment, and improvement in their condition was sustained during the long-term follow-up. Side effects of IM clozapine were similar to those of oral clozapine, but its sedative and cardiovascular effects (hypotension and tachycardia) had faster onset following IM administration. After long-term use, clozapine injections lead to local swelling and to the formation of painful nodules in some patients. In summary, IM clozapine may facilitate successful transition to oral clozapine in most patients, and it definitely represents a valuable tool for addressing refusal of oral clozapine in patients with treatment-refractory schizophrenia. More studies, especially focused on its safety, are, however, needed to better understand the limitations of this novel treatment approach.
