Outcome of first contact schizophrenia in Jamaica.

Several previous studies have identified high incidence rates, high relapse rates and poor short-term outcome for schizophrenia in African-Caribbeans in the United Kingdom (UK). Studies in the Caribbean have found the incidence of schizophrenia to be within worldwide levels, and one-year outcome to be much lower than that reported for African Caribbean patients in the UK. First contact patients with schizophrenia identified prospectively by the Present Status Examination were followed prospectively for one year.

Treatment of acute schizophrenia in open general medical wards in Jamaica.

Objective: The study assessed the efficacy of treating acute psychotic illness in open medical wards of general hospitals.

Methods: The sample consisted of 120 patients with schizophrenia whose first contact with a psychiatric service in Jamaica was in 1992 and who were treated as inpatients during the acute phase of their illness. Based on the geographic catchment area where they lived, patients were admitted to open medical wards in general hospitals, to psychiatric units in general hospitals, or to acute care wards in a custodial mental hospital.

Incidence of HTLV-I-associated myelopathy/tropical spastic paraparesis (HAM/TSP) in Jamaica and Trinidad.

HTLV-I is sexually transmitted more efficiently from men to women than vice versa, and the majority of HTLV-I endemic areas report a female preponderance of HTLV-I-associated myelopathy/tropical spastic paraparesis (HAM/TSP) cases. The objective of this study was to estimate the gender- and age-specific incidence rates of HAM/TSP in the general population as well as in the HTLV-I-infected population in Jamaica and in Trinidad and Tobago. Incidence rates for HAM/TSP were computed based on all reported incident cases in both countries between 1990 and 1994.

Anterior horn cell degeneration in polymyositis associated with human T lymphotropic virus Type-1 in patients from Barbados.

Anterior horn cell degeneration has only occasionally been noted in patients with tropical spastic paraparesis associated with human T lymphotropic virus type-1 (HTLV-1) infection. We report on three adult patients with HTLV-1-associated polymyositis who had clinical evidence of anterior horn cell degeneration. One patient had moderate proximal weakness and muscle wasting in all four limbs, while two had mild upper limb weakness with more profound proximal weakness and wasting in the lower limbs.
