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.

Materials And Methods: A retrospective review was performed of men who underwent RP for clinically organ-confined (OC) prostate cancer between 2000 and 2011 at Columbia University Medical Center (New York, USA) and the University Hospital of the West Indies (Kingston, Jamaica) between 2000 and 2007. Men who had received neoadjuvant or adjuvant (within 3 months) therapy were excluded.
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.

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.
Background: An autopsy study of aortic dissection (AD) at our institution was previously reported. In the approximately 20 years since then, however, many aspects of diagnosis and treatment of this disease have changed, with a fall in mortality reported in many centers around the world. An impression amongst our pathologists that, there might be an increase in the prevalence of AD in the autopsy service at our hospital, since that earlier report, led to this repeated study, in an attempt to validate that notion.

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.

This report highlights a case of obstructive jaundice in a 46-year-old West Indian man that resulted from an extramedullary plasmacytoma.
Case Presentation: A 46-year-old West Indian man presented to our hospital with evidence of a significant upper gastrointestinal bleed.
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.

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.
Our aim was to study the level of interobserver concordance in the Gleason scores of prostate needle biopsy specimens reported at 1 institution. A retrospective review of all prostate needle biopsy specimens in which a diagnosis of adenocarcinoma was made during the year 2000 was conducted. Parameters evaluated included the Gleason score, Gleason grades identified, the percentage of Gleason grades 4 and 5, and the percentage of tumor in the biopsy specimen.

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.
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.
