Charles Bonnet Syndrome (CBS) is diagnosed when a patient who is psychiatrically intact experiences visual hallucinations in the setting of significant visual acuity or field loss. The exact pathophysiology of the CBS hallucinations remains largely unknown. The main theories include the deafferentation theory and perceptual release theory.

- - Scabies is a common skin condition caused by a mite, leading to very itchy bumps, typically found in specific areas like hands, groin, and armpits, but can occasionally spread widely and worsen into severe forms like crusted scabies.
- - A case study of a 69-year-old man reveals that he developed crusted scabies alongside other health issues, including immune thrombocytopenic purpura and muscle weakness, after self-medicating with corticosteroids.
- - Despite effective treatment for scabies, the patient tragically died from bacterial sepsis, highlighting the risk of misdiagnosis and complications that can arise from using immunosuppressive medications to treat mistaken diagnoses.
Objective: This study analyzed hospital readmission rates of patients with schizophrenia who were treated with long-acting injectable antipsychotics (LAIs) or with oral antipsychotics after being discharged from a hospitalization.
Methods: Medical claims of patients with schizophrenia who were ages 18-64 and had a first hospitalization for a serious mental illness (index hospitalization, October 2007 through September 2012) and at least one prescription for a first- or second-generation antipsychotic were analyzed from the Truven Health MarketScan Multi-State Medicaid Database. Analyses were conducted for patients with a sole diagnosis of schizophrenia (N=1,450) and for all patients with schizophrenia (N=15,556), which added patients with a codiagnosis of bipolar disorder or major depressive disorder.
Background: Treatment during first-episode psychosis (FEP) or early schizophrenia may affect the rates of relapse and remission, as well as cognitive functioning, over time. Prolonged duration of psychosis is associated with a poor prognosis, but the effects of treatment in patients with FEP or early schizophrenia on the long-term outcomes are not well defined.
Objective: To understand the long-term effects of treatment with antipsychotic agents on remission, relapse, and cognition in patients with FEP or early schizophrenia.
Background: Database analyses have indicated that medical treatment for schizophrenia varies among racial groups. This study assessed antipsychotic use and healthcare utilization across races in Medicaid-insured patients with schizophrenia.
Methods: A Medicaid database of inpatient/outpatient medical claims and outpatient prescription claims for more than 28 million enrollees in 11 geographically diverse states was analyzed.
