RESUMO
We report a case of eumycetoma due to Madurella mycetomatis affecting the left dorsal forefoot in a 35-year-old woman. She had spent her childhood in Jamaica, and had been resident in the U.K. for 20 years prior to her presentation. She gave a highly suggestive history for a mycetoma, having observed the intermittent discharge of black grains from the lesion. The diagnosis was confirmed by histological and mycological analysis of the grains, and a magnetic resonance imaging scan excluded osteomyelitis. She has responded very favourably to treatment with itraconazole. Mycetomas due to M. mycetomatis have not previously been reported from Jamaica.

Cause of mortality was studied in waterfowl in hypersaline playa lakes of southeast New Mexico during spring and fall migration. Mortality was not common in wild ducks resting on the playas during good weather. However, when birds remained on the lakes for prolonged periods of time, such as during experimental trials and stormy weather, a heavy layer of salt precipitated on their feathers. Sodium toxicity was the cause of death for all experimental mallards housed on playa water and for 50% of the wild waterfowl found moribund or dead during the spring of 1995. Gross lesions included heavy salt precipitation on the feathers, ocular lens opacities, deeply congested brains, and dilated, thin-walled, fluid-filled cloacae. Microscopic lesions in the more severely affected birds included liquefaction of ocular lens cortex with lens fiber swelling and multifocal to diffuse ulcerative conjunctivitis with severe granulocytic inflammation, edema, and granulocytic vasculitis resulting in thrombosis. Inflammation similar to that seen in the conjunctiva occasionally involved the mucosa of the mouth, pharynx, nasal turbinates, cloaca, and bursa. Transcorneal movement of water in response to the hypersaline conditions on the playa lakes or direct contact with salt crystals could induce anterior segment dehydration of the aqueous humor and increased osmotic pressure on the lens, leading to cataract formation.

Characteristics of clinically diagnosed cases of tinea capitis from Trinidad are described. Tinea capitis comprised 29.5% of all dermatophytoses seen at one general hospital out-patient dermatology clinic during a one-year period. Males were more often affected than females and there was a predominance of patients of African descent. Among the dermatophytes cultured Trichophyton tonsurans was the most prevalent (52.9%), followed by Microsporum canis (20.0%) and M. audouinii (18.6%). Less frequent isolates included M. gypseum (1.9%), T. mentagrophytes var granulare (1.4%) and T. rubrum (1.4%).

Characteristics of clinically diagnosed cases of tinea capitis from Trinidad are discribed. Tinea capitis comprised 29. percent of all dermatophytoses seen at one general hospital out-patient dermatology clinic during a one-year period. Males were more often affected than females and there was a predominance of patients of African descent. Among the dermatophytes cultured Trichophyton tonsurans was the most prevalent (52.9 percent), followed by Microsporum canis (20.0 percent) and M. audouin ii (18.6 percent). Less frequent isolates included M. gypseum (1.9 percent), T. mentagrophytes var granulare (1.4 percent) and T. rubrum (1.4 percent) (AU)
