RESUMO

Eumycetoma is a localized, chronic fungal infection of skin and subcutaneous tissues. It is characterized by tumefaction, abscess formation, draining sinuses, and sclerotia (grains) within the abscesses and fistulae. Treatment of eumycetoma is a challenge. Relapse rates are high even when a combination of surgical and medical approaches is utilized. Here we report a case of eumycetoma due to Exophiala jeanselmei arising on the foot of a man from Trinidad, West Indies.

RESUMO

Eczema in the tropics is a common problem. Although it is a major cause of discomfort among children worldwide, a warm tropical climate often has important repercussions for children with dermatitis. The original description by Sweet empahasized that interest in tropical eczemas extended to the English, as children of West Indian immigrants in England were affected. Likewise, immigrants may carry these disorders with them to the United States. In Jamaica, a tropical country, the largest and most populous of the English-speaking Caribbena islands, eczema is by far the most common skin disorder seen in children attending dermatology clinics. Reports from other Caribbean islands suggest that this is true for the region as a whole. In 1981, Alabi and La Grenade reported that from 1971 to 1975 eczema accounted for 46.7 percent of skin rashes seen in children at the University Hospital of the West Indies. Review of the period 1988 to 1993 showed that 52 percent of the 601 children who attended the skin clinic for the first time had eczema, confirming the earlier finding. In this latter review, atopic eczema was the most common type of eczema (52 percent), followed by seborrheic eczema (20 percent) and infective dermatitis (10 percent). The remaining 18 percent had a variety of unclassified eczemas including pityriasis alba, discoid eczema, acute vesicular eczema of the hands and/or feet, and hyperkeratotic eczema of the feet.(AU)

RESUMO

A possible causal association between infective dematitis and HTLV-I infection was reported familial infective dematitis (ID) occurring in a 26-year-old mother and her 9-year-old son. The mother was first diagnosed with ID in 1969 at the age of 2 years in the Dermatology Unit at the University Hospital of the West indies (U.H.W.I.) in Jamaica. The elder of her 2 sons was diagnosed with ID at the age of 3 years, also at U.H.W.I. Both mother and son are HTLV-I-seropositive. A second, younger son, currently age 2 years, is also HTLV-I-seropositive, but without clinical evidence of ID. Major hitocompatibility complex (MHC), class II, human leucocyte antigen (HLA) genotyping documented a shared class II haplotype, DRB*DQBI* (1101-0301), in the mother and her 2 sons. This same haplotype has been described among Japanese patients with HTLV-I-associated myelopathy/tropical spastic paraparesis (HAM/TSP), and has been associated with a possible pathologically heightened immune repsonse to HTLV-I infection. The presence of this haplotype in these familial ID cases with clinical signs of HAM/TSP may have contributed to their risk for development of HAM/TSP. The unaffected, HTLV-I seropositive younger son requires close clinical follow-up. (AU)

RESUMO

Cattle, horses, sheep and goats in all areas of St. Lucia were examined to ascertain the prevalence and distribution of streptothricosis on the island and to investigate its association with the occurrence of Amblyomma variegatum ticks. Although the disease was found to occur throughout St. Lucia it was more prevalent and generally of a more severe form in areas where A. variegatum ticks are present. A tick control programme in the north of the island appeared to have resulted in a dramatic reduction in the prevalence of the disease. (AU)

RESUMO

In Jamaican children infective dermatitis is chronic eczema associated with refractory nonvirulent Staphylococcus aureus or beta haemolytic streptococcus infection of the skin and nasal vestibule. 14 children between the ages of 2 and 17 years with typical infective dermatitis, attending the dermatology clinic at the University Hospital of the West Indies in Jamaica, were tested for antibody to human T-Lymphotropic virus type 1 (HTLV-1). All were seropositive, whereas 11 children of similar age with atopic eczema were all negative. In 2 of 2 cases of infective dermatitis, the biological mother was HTLV-1 seropositive. None of the 14 patients showed signs of adult T-cell leukaemia/lymphoma, though experience with previous cases of infective dermatitis indicates the possibility of such progression. (AU)

RESUMO

Skin infection is common in patients with any skin diseases where pruritus is a prominent feature. A retrospective analysis was performed on the results of skin swab cultures from patients with eczema and a variety of other conditions. This paper presents the findings of bacteriologic culture and sensitivity testing of 131 swabs from 122 patients over a period of 22 months and examines the results in terms of the reported relationship between scabies and acute poststreptococcal glomerulonephritis. Staphylococcus aureus was most often isolated, and this appears to indicate that antistaphylococcal antibiotics should be the first line of treatment in the absence of the results of cultures. (AU)

RESUMO

The association between the occurrence of Amblyomma variegatum ticks and streptothricosis was higher on animals having A. variegatum ticks compared to that of animals not infested with A. variegatum ticks. There was a steady increase in the prevalence of severe lesions as the level of infestation with adult A. variegatum ticks increased. However the distribution of skin lesions could not be related to the predilection feeding sites of adult A. variegatum ticks (Summary)

RESUMO

The incidence of skin disease in people seeking health care in rural Jamaica during the period January to December 1985 has been studied. Results indicate that of 14,179 clinic visits reviewed, 6 percent involved a primary dermatological diagnosis. Infectious and parasitic diseases predominated, with scabies, impetigo, and tinea being the most common diagnoses. Of these, scabies accounted for nearly one third of all dermatologic visits. Noninfectious skin disease accounted for less than 10 percent of dermatologic diagnosis, with unclassified eczema making up the majority. Undiagnosed skin conditions contributed one third of dermatologic visits, with an incidence inversely related to the incidence of scabies visits. This relationship suggests that many evaluations of skin conditions were based on the exclusion of scabies with no alternative diagnosis. (AU)

RESUMO

During 1982-83 there was a substantial increase in the number of S. ohio infections at the University Hospital of the West Indies, which coincided with the appearance of strains resistance to chloramphenicol, cotrimoxazole, ampicillin, neomycin and carbenicillin. Multiresistance strains of S. ohio accounted for 19.3 percent of all salmonella isolates during this period and all of 40 strains tested were able to transfer resistance determinants to E. coli K12 J 53-2. S. ohio was cultured from stool (60), blood (5), wounds and abscesses (4) and postmortem material (2). Eighty-six percent of S. ohio infections occurred in children of 3 years old or less. There was a high incidence of gastroenteritis in malnourished children, a 14 percent incidence of localizing infections and a 7 percent incidence of septicaemia. Two infants with severe gastroenteritis and bronchopneumonia died. There were a number of unusual infections including two cases of septicaemia in children receiving chloramphenicol for Haemophilus infleunzae meningitis, a scrotal abscess secondary to extravastion of urine and infected scabies in a child with marasmic kwashiorkor.(Summary)

RESUMO

Patients with nephritis and schoolchildren in South Trinidad were surveyed for the presence of Corynebacterium diphtheriae in throats and skin lesions. The incidence of positive cultures was higher in skin leisons than in throat cultures. None of the children experienced symptoms of systemic intoxication. Subsequent to the increase in cutaneous infections, however, the indidence of symptomatic nasopharyngeal diphtheria also increased in Trinidad, suggesting that the skin lesions constituted an important reservior of infection. One group of schoolchildren was reexamined after six months, and the levels of antitoxin in serum were correlated with the presence of C. diphtheriae in skin leisons and throat cultures. The high levels of antitoxins observed apparently resulted from natural immunization in the absence of clinical signs of diphtheria. No effect of C. diphtheriae was noted on the colonization of skin lesions by streptocci or on the incidence of acute glomerulonephritis in the population. (AU)

RESUMO

In September, 1970, an increasing number of the patients admitted with acute glomerulonephritis to San Fernado General Hospital in Trinidad were noted to have skin lesions characteristic of scabies. á-haemolytic streptococci were isolated from these lesions and also from similar scabetic lesions in members of the patients' families, in " normal" schoolchildren, and in the general population of a small village. Concomitantly, many dogs in nephritic households, as well as others running wild, were observed to have lesions compatible with scabies from which á-haemolytic streptococci also were isolated. Sarcoptes scabiei were indentified in lesions of both patients and dogs and were morphologically indentical. After the onset of this infestation with scabies, the admission-rate of patients with acute proportions which have proved, since this study, to be the beginning of the largest epidemic of acute glomerulonephritis yet recorded in Trinidad.(AU)

RESUMO

The relation of seven different M types of streptococci to acute glomerulonephritis associated with skin lesions in South Trinidad has been studied by means of type-specific antibody assays as well as by isolation and identification of the strains. The data indicate that, one after another, five of these strains have prevailed among patients with acute glomerulonephritis during the past five years. At least three of the strains (M-types 55,49,57, and/or 60) were associated with epidemic increases in nephritis cases. The appearance of five consecutively predominant types of nephritogenic streptococci during a relatively short period of time is in contrast to the continuing prevalence of M-type 12 strains among nephritogenic streptococci primarily associated with respiratory infections in temperate zones. These observations suggest that the skin sores commonly found on children in tropical Trinidad, provide a particularly suitable environment for development of nephritogenic types. It remains to be seen whether these types will recur or whether new types will continue to emerge in Trinidad. (AU)

RESUMO

We will present bacteriological evidence for an association of acute glomerulonephritis with several streptococcal strains isolated from skin lesions in Trinidad; Types 52 and 55 during the first wave and type 49 during the second wave of the 1964-65 epidemic; atypical "type 2" in a sub-epidemic rise in cases during an endemic year; type 57 during a subsequent epidemic period; and type 60 most recently. Immunological confirmation of association of these strains with acute glomerulonephritis was obtained only for type 55. Low incidence of serum type specific antibodies to types 49 and "type 2" may be attribued to their poor antigenicity. However, this is not the case with type 57. Emergence of at least five and perhaps six apparently new types of nephritogenic streptococci during a relatively short period suggests that each recurrent epidemic wave of acute nephritis is the result of a newly introduced or newly developed strain of nephritogenic streptococci. Several questions might be asked: From where do these different types come?. Are they brought into Trinidad from outside or do they represent local mutants? Does a skin infection represent a particularly suitable environment for development of new streptococcal antigens? (AU)

RESUMO

An epidemic of acute glomerulonephritis in Trinidad led to an investigation into strepococcal skin infection, as most nephritis cases were asssociated with this. Hippelates in this region commonly feed on skin lesions, infected or otherwise. Some of these flies captured in the vinicity of infected children were found to be contaminated with Streptococcus pyogenes; 3 species were involved, H. peruanus, H. flavipes and H. currani. The naturally-acquired infection lasted for 28 hours or more, and the flies would return to human bait while still infectious. The Hippelates population and the streptococcal skin infection rate at one school showed similar changes. Hippelates probably contribute to the rapid spread of streptococci throughout the island, and to the frequency of infection with more than one serotype; they may also contribute to the high incidence of streptococcal skin infection, but this requires further evidence.

RESUMO

The recent epidemic of acute glomerulonephritis in Trinidad had two peaks, separated by an interval of about 6 months. Evidence is presented that there were in fact two successive but overlapping epidemics, the first due to streptococci of provisional M-type 55, and second to streptococci of M-type 49. (AU)

RESUMO

An Intensive Streptococcal Surveillance of two South Trinidad Schools differing in topographical surroundings and ethnic composition has been done for five months. Throat and skin sore cultures were obtained from samples of children of volunteer families. Additional cultures were obtained from non-sample schoolmates who developed skin sores. The data and findings are as follows: 1. Skin sores were found mainly on the extremities. 2. Males have more skin sores than females in a ratio of over 2:1 for males versus females. 3. The highest incidence of skin sores, was found in the five to six (5-6) year old population. 4. In the school sample 22.7 percent developed skin sore, 68.8 percent were positive for Beta-hemolytic Streptococci and 79.4 percent were Group-A. 5. 78.9 percent of all skin sores contained Beta-hemolytic Streptococci. 6. 77.3 percent of Beta-hemolytic Streptococci were Group-A. 7. The prevalence and incidence of skin sores, Beta-hemolytic Streptococci and Group-A Streptococci was highest at the end of December. (The end of the wet season). 8. 18.7 percent of the subject studied had Beta-hemolytic Streptococci in their throats; of these 25.4 percent were Group-A. 9. Of other streptococcal groups - throat cultures were high in Group-G while skin sores were high in Group-C. 10. The mean length of time that Beta-hemolytic Streptococci remained in skin sore was four (4) weeks. Sores themselves may be the reservoir for Group-A Streptococci. 11. The mean length of time that Beta-hemolytic Streptococci remained in the throat was two (2) weeks(Summary)
