BACKGROUND: Chromomycosis is a rare mycotic infection encountered in tropical and subtropical regions. The disease presents as a slowly-evolving nodule that can become infected with bacteria. Here, we describe a unique association of abscesses caused by a chromomycosis and Listeria monocytogenes in a kidney transplant recipient, and didactically expose how the appropriate diagnosis was reached. CASE PRESENTATION: A 49-year old male originating from the Caribbean presented a scalp lesion which was surgically removed in his hometown where it was misdiagnosed as a sporotrichosis on histology, 3 years after he received a kidney transplant...

BACKGROUND: Population-based Cancer registries (PBCR) play an important role in cancer surveillance and research. The aim of this study was to examine overall survival in elderly patients with colorectal cancer (CRC) by analysing data from the Martinique PBCR between 1993 and 2012. METHODS: The log-rank test was used to assess the statistical differences of the survival curves by each categorical variable: age at diagnosis, sex, histology, zone of residence, subsite, stage at diagnosis, and chemotherapy...

Objective The objective of this study was to examine neuropsychiatric lupus in a Black Caribbean population. Methods We reviewed Barbados National Lupus Registry patients with ≥4 American College of Rheumatology criteria and a diagnosis of neuropsychiatric lupus using the American College of Rheumatology 19 case definitions. Results From 366 patients with four or more American College of Rheumatology criteria for systemic lupus erythematosus, 55 (15%) had evidence of neuropsychiatric lupus. There were 51 females and four males (F:M = 13:1) with a median age of 31 years...

The recently described epizoic sponge-sponge symbioses between Xestospongia deweerdtae and two species of Plakortis present an unusual series of sponge interactions. Sponges from the genus Plakortis are fierce allelopathic competitors, rich in cytotoxic secondary metabolites, and yet X. deweerdtae flourishes as an epizoic encrustation on Plakortis deweerdtaephila and Plakortis symbiotica. Our objective in this study was to evaluate the hypothesis that X. deweerdtae grows epizoic to these two species of Plakortis due to a shared chemical defense against predators...

Sickle cell anaemia (SCA) is a common haemoglobinopathy among people from the Middle East, the Afro-Caribbean region, the Mediterranean and East India. While osteomyelitis of the long bones is a well-documented complication of SCA, there are few documented cases of SCA patients presenting with jaw osteomyelitis. We report three SCA patients with chronic jaw osteomyelitis who presented to the Department of Oral Health, Sultan Qaboos University Hospital, Muscat, Oman, between 2009 and 2013. Two of the patients had osteomyelitis of the mandible and the third had osteomyelitis of the maxilla...

BACKGROUND: In high-income countries patients with Huntington disease (HD) typically present to healthcare providers after developing involuntary movements, or for pre-symptomatic genetic testing if at familial risk. A positive family history is a major guide when considering the decision to perform genetic testing for HD, both in affected and unaffected patients. Management of HD is focused upon control of symptoms, whether motor, cognitive, or psychiatric. There is no clear evidence to date of any disease-modifying agents...

INTRODUCTION: Some studies suggest that thrombotic thrombocytopenic purpura (TTP) occurs more often in African Americans. However there is low evidence for this in the literature. The aim of our study was to describe the clinical and biological characteristics of TTP in the Afro-Caribbean population of Martinique. METHODS: We retrospectively analysed all patients with TTP diagnosed at the Fort-de-France hospital between 2008, January 1st and 2015, December 31st...

Mutualisms could be evolutionarily unstable, with changes in partner abundances or in the spatial context of interactions potentially promoting their dissolution. We test this prediction using the defense mutualisms between species of the Neotropical genus Cecropia and Azteca ants. A new, multigene phylogeny with representatives of all five genera of Cecropieae (most of them from the Neotropics) and half of the 61 species of Cecropia shows the West African endemic Musanga (2spp.) as sister to Cecropia, implying dispersal from the Neotropics to Africa, with a molecular clock suggesting that this occurred about 23Mya...

BACKGROUND: This study investigates the role of ethnicity in pathways to emergency mental health care in Toronto for clients with psychosis, while taking into account neighborhood factors. Previous literature has focused on Afro-Caribbean clients, reporting an increased risk of accessing mental health care through negative pathways. METHODS: A retrospective chart review for clients from 6 different ethnic origin groups presenting with psychosis - East Asian, South Asian, Black African, Black Caribbean, White European, and White North American - was undertaken in a psychiatric emergency department (ED)...

Objectives.: To evaluate whether genetic and environmental factors associated with RA in European and Asian ancestry populations are also associated with RA in African ancestry individuals. Methods.: A case-control study was undertaken in 197 RA cases and 868 controls of African ancestry (Black African, Black Caribbean or Black British ethnicity) from South London. Smoking and alcohol consumption data at RA diagnosis was captured. Genotyping was undertaken (Multi-Ethnic Genotyping Array) and human leukocyte antigen (HLA) alleles imputed...

INTRODUCTION: Transgender women are disproportionately impacted by HIV. Transgender women involved in sex work may experience exacerbated violence, social exclusion, and HIV vulnerabilities, in comparison with non-sex work-involved transgender women. Scant research has investigated sex work among transgender women in the Caribbean, including Jamaica, where transgender women report pervasive violence. The study objective was to examine factors associated with sex work involvement among transgender women in Jamaica...

INTRODUCTION: Young men who have sex with men (MSM) in Jamaica have the highest HIV prevalence in the Caribbean. There is little information about HIV among transgender women in Jamaica, who are also overrepresented in the Caribbean epidemic. HIV-related stigma is a barrier to HIV testing among Jamaica's general population, yet little is known of MSM and transgender women's HIV testing experiences in Jamaica. We explored perceived barriers and facilitators to HIV testing among young MSM and transgender women in Kingston, Jamaica...

In 2003, the PHDG (Prevalence of Hypertension among Disadvantaged Guadeloupeans) study highlighted poor management of hypertension in an unemployed French Caribbean population. New processes of health-care coordination and a pay-for-performance system have since been developed. We aimed to assess changes in hypertension characteristics in disadvantaged French Caribbean populations in the last 10 years. Using PHDG 2003 data, in 2014 we undertook a cross-sectional study with identical methods. The source population comprised all Guadeloupeans having undergone periodic heath checks offered by the Social Security insurance at these dates...

Emerging research suggests that both perceptions of discrimination and internalized racism (i.e., endorsement of negative stereotypes of one's racial group) are associated with poor mental health. Yet, no studies to date have examined their effects on mental health with racial/ethnic minorities in the US in a single study. The present study examined: (a) the direct effects of everyday discrimination and internalized racism on risk of DSM-IV criteria of past-year major depressive disorder (MDD); (b) the interactive effects of everyday discrimination and internalized racism on risk of past-year MDD; and (c) the indirect effect of everyday discrimination on risk of past-year MDD via internalized racism...

This study describes the genetic diversity and population structure of 194 native maize populations from 23 countries of Latin America and the Caribbean. The germplasm, representing 131 distinct landraces, was genetically characterized as population bulks using 28 SSR markers. Three main groups of maize germplasm were identified. The first, the Mexico and Southern Andes group, highlights the Pre-Columbian and modern exchange of germplasm between North and South America. The second group, Mesoamerica lowland, supports the hypothesis that two separate human migration events could have contributed to Caribbean maize germplasm...

Aedeomyia squamipennis (Lynch Arribalzaga) is a tropical mosquito (Diptera: Culicidae) found throughout most of the American Tropics, from eastern Mexico through Argentina, including several Caribbean islands. Larvae are typically associated with bodies of water with dense growths of aquatic vegetation, particularly Pistia stratiotes L., water lettuce. Adult females feed predominantly on the blood of birds and seek hosts in forest canopies. Aedeomyia squamipennis is considered an important vector of Gamboa virus and avian malaria, and is also suspected of transmitting Venezuelan equine encephalitis virus...

Several arboviruses have emerged and/or reemerged in the New World in the past decades. Zika and chikungunya viruses, formerly restricted to Africa and perhaps Asia, invaded the continent, causing great concern. Dengue virus outbreaks have continued to occur in almost all countries, with millions of cases per year. West Nile virus rapidly invaded North America, and now cases have been found in Central and South America. Other arboviruses, such as Mayaro and Eastern equine encephalitis viruses, have increased their activity and have been found in new regions...

Girls' school participation has expanded considerably in the developing world over the last few decades, a phenomenon expected to have substantial consequences for reproductive behaviour. Using Demographic and Health Survey data from 43 countries, this paper examines trends and differentials in the mean ages at three critical life-cycle events for young women: first sexual intercourse, first marriage, and first birth. We measure the extent to which trends in the timing of these events are driven either by the changing educational composition of populations or by changes in behaviour within education groups...

BACKGROUND: Diabetes and pre-diabetes are prevalent in acute coronary syndrome (ACS) and relate to adverse outcomes. This study used HbA1c to screen for degrees of glucose intolerance amongst patients without known diabetes presenting with ACS. METHODS: Over a 1-year period (June 2014-2015) consecutive patients admitted to a single centre cardiology unit with an initial diagnosis of ACS without prior diabetes diagnosis were electronically referred to our diabetes team...

We present a case report of a traveller injured by a needlefish in the Caribbean. The needlefish leapt from the ocean and struck the traveller's face at high speed, causing a seemingly superficial puncture wound on his nose. Later, it became apparent that multiple fish bones had broken off and lodged in his nasal cavity, very narrowly missing his cribriform plate. Some bones were discharged spontaneously through his nose over the next 3 months, and one required surgical removal. Our report highlights the importance of urgent radiological examination in patients injured by needlefish, even if the external wound appears insignificant...
