Vitamin D Deficiency at Diagnosis Increases All-Cause and Prostate Cancer-specific Mortality in Jamaican Men.

Background: 25 hydroxyvitamin D [25(OH)D] and serum calcium have been associated with incident prostate cancer (PCa). However, there is limited data on whether these metabolites predict survival in men of African descent, a population disproportionately affected by PCa. We studied the relationship of 25(OH)D at PCa diagnosis with all-cause and cancer-specific mortality among Jamaican men and examined whether serum calcium modified any associations.

Both serum 25-hydroxyvitamin D and calcium levels may increase the risk of incident prostate cancer in Caribbean men of African ancestry.

Circulating 25-hydroxyvitamin D [25(OH)D] concentrations have been associated with both higher and lower risk of prostate cancer (PCa), whereas elevated levels of circulating calcium has been related to higher risks. However, there are few studies that account for effects of both calcium and 25(OH)D concentrations on incident PCa in a black population. We examined these relationships in a case-control study of men 40-80 years old with newly diagnosed, histologically confirmed PCa in Jamaica, a tropical country.

Disseminated trichosporonosis in a burn patient: meningitis and cerebral abscess due to Trichosporon asahii.

A 44-year-old diabetic female presented to a hospital in Jamaica with thermal burns. Trichosporon asahii was isolated from facial wounds, sputum, and a meningeal swab. Dissemination of the fungus was demonstrated in stained histological sections of the meninges and a brain abscess at autopsy.

Associations of whole-blood fatty acids and dietary intakes with prostate cancer in Jamaica.

Objective: To investigate the association of whole-blood fatty acids and reported intakes of fats with risk of prostate cancer (PCa).

Design: Case-control study of 209 men 40-80 years old with newly diagnosed, histologically confirmed prostate cancer and 226 cancer-free men attending the same urology clinics. Whole-blood fatty acid composition (mol%) was measured by gas chromatography and diet assessed by food frequency questionnaire.

Body size and risk of prostate cancer in Jamaican men.

We investigated the associations between body size and risk of prostate cancer in a hospital-based case-control study in Jamaica. Height, weight, waist, and hip circumference were measured at enrollment, and data collected on medical and lifestyle factors for newly diagnosed cases (n = 243) and controls (n = 275). Compared with men in the normal range of waist-hip ratio (WHR), men with WHR > or =0.

A 6-year analysis of the clinicopathological profile of patients with prostate cancer at the University Hospital of the West Indies, Jamaica.

OBJECTIVE To document the clinicopathological characteristics of prostate cancer in a public hospital-based population in Jamaica, over a 6-year period, and examine any trends in these characteristics over time, as prostate cancer is the leading cause of cancer in Jamaican men, but there are few published reports documenting the clinicopathological profile of this disease in the Jamaican population. PATIENTS AND METHODS All patients consecutively diagnosed with prostate cancer by transrectal ultrasonography-guided biopsy at the University Hospital of the West Indies, from January 2000 to December 2005, were identified at time of diagnosis, and relevant clinical and pathological data collected from the accompanying histopathology request forms. RESULTS There were 529 cases of prostate cancer diagnosed over the 6 years.

Primary tumors of the heart: experience at the University Hospital of the West Indies.

Background: An analysis of primary cardiac tumors in the English-speaking Caribbean has never been previously conducted. This paper is an attempt to fill this void.

Methods: A retrospective review of autopsy and surgical pathology records of the Department of Pathology at the University Hospital of the West Indies was carried out in search of all primary cardiac tumors.

Use of the Gleason system in international comparisons of prostatic adenocarcinomas in blacks.

Background: Comparisons of prostate cancer in blacks living in different countries can shed light on factors responsible for high rates of the disease among blacks in America. Since the prognostic value of the Gleason grading system is well established, we assessed agreement between pathologists in countries where black populations of the African Diaspora reside.

Methods: Three genitourinary pathologists at hospitals in Nigeria, Jamaica, and the US independently assessed sextant biopsies from 12 patients.

Leiomyosarcoma of the uterus with a florid intravascular component ("intravenous leiomyosarcomatosis").

A leiomyosarcoma of the uterus in a 54-year-old woman exhibited striking involvement of large vessels of the myometrium and broad ligament on both gross and microscopic examination. The pattern of vascular involvement resembled that seen in intravenous leiomyomatosis. Imaging studies showed recurrent tumor within the inferior vena cava 3 months after hysterectomy.
