The objective of this study was to characterize the demographics and population health of four slum communities in Port-au-Prince, Haiti, including population density and the burden of communicable and non-communicable diseases. Four urban slums were surveyed using a population-representative design between July and October 2016. A multistage cluster area random sampling process was used to identify households and individuals for the survey. Household surveys included rosters of residents, household characteristics, adult and child deaths in the past year, child health, and healthcare access and utilization. Individual surveys of two randomly sam-pl ed adults f rom each household incl uded sociodemographic data, maternal health, and adult health. Additionally, blood pressure, height, weight, and psychological distress were measured by study staff. Data were weighted for complex survey design and non-response. A total of 525 households and 894 individuals completed the survey (96% household and 90% individual response rate, respectively). The estimated population density was 58,000 persons/km 2. Across slums, 55% of all residents were female, and 38% were adolescents and youth 10-24 years. Among adults, 58% were female with median age 29 years (22-38). The most common adult illnesses were severe psychological distress (24%), hypertension (20%), history of physical injury/ trauma (10%), asthma (7%), history of cholera (4%), and history of tuberculosis (3%). Ten percent of adults had obesity (BMI > 30 kg/m 2), and 7% currently smoked. The most common under-5 diseases during the last 3 months were respiratory and gastrointestinal illnesses (50% and 28%, respectively). One-third of households reported needing medical care for a child in the past year but not being able to access it, largely due to financial constraints. Unique features of these slums are a population structure dominated by adolescents and youth, a high proportion of females, and a high burden of noncommunicable diseases including hypertension and psychological distress. Screening, diagnostic, and disease management interventions are urgently needed to protect and promote improved population health outcomes in these slum communities.

Paliperidone is an atypical antipsychotic medication commonly used to treat schizophrenia, schizoaffective disorder, and bipolar disorder. It is a metabolite of risperidone and has a similar mechanism of action, primarily blocking dopamine 2 receptors (D2 receptors) in the brain. Paliperidone has various adverse effects, including extrapyramidal symptoms, weight gain, and metabolic disturbances. Catatonia is rare but severe side effects can occur in the context of an underlying psychiatric, neurologic, or general medical condition. Paradoxically, antipsychotics for treating schizophrenia or bipolar spectrum disorders can precipitate or worsen catatonic symptoms. The report suggests that 17-19% of all cases diagnosed as catatonia due to other medical conditions are medication-induced. Catatonia is a neuropsychiatric syndrome that presents as a cluster of psychomotor signs and symptoms resulting in movement and behavior aberrations. Various symptoms, including mutism, stupor, rigidity, and abnormal movements, characterize catatonia. Catatonia is a potentially life-threatening condition requiring prompt recognition and management. Here, we present a case of a patient with catatonia associated with long-acting injectable paliperidone intramuscular therapy in a patient with schizophrenia.
