[Onychomycoses caused by non-dermatophytic filamentous fungi in Cádiz].

Background: The incidence and clinical significance of other than dermatophytes fungi or moulds causing onychomycosis is unknown, because they may be colonising organisms rather than pathogen. This report presents the results of a study conducted between 1997 and 1999 to determine the incidence and aetiology of onychomycosis by non-dermatophytic filamentous fungi in the population of Cádiz (Spain).

Patients And Methods: Diagnosis of onychomycosis was performed by direct microscopic examination, culture and, some times, by histologic examination, on samples from 610 patients with clinical suspected fungal nail infections.

The authors comment the interest of the X Ray microanalysis in Dermatology and, especially, the Cu/Zn index determination in cutaneous tumors.

[Adquired epidermolysis bullosa. Immunopathological and ultrastructural studies].

A case of epidermolysis bullosa acquisita (EBA) in a 64 year old man is reported. The direct immunofluorescence showed a positive lineal anti IgG basement membrane on the affected skin (blisters and provocation tests) and on the univolved healthy skin. The electron microscopic studies showed a "dermolysis".

Scanning electron microscopic and X ray microanalysis study of the mineral deposits in pseudoxanthoma elasticum.

A skin biopsy of a 37 year old man with typical lesions of pseudoxanthoma elasticum (P.E.) associated with angioid streaks (Groenbald-Strandberg Syndrom) was examined with a scanning E.

[Groenblad-Strandberg syndrome. Study with scanning microscopy provided with an X rays analyzer].

A skin biopsy a 37 year old man with typical lesion of pseudoxanthoma elasticum associated with angioid striae (Groenblad-Strandberg syndrome) was examined with a scanning EM (SSM-2A) and a scanning EM provided with a X ray microanalyser. With the scanning EM (SSM-SA) it was possible to see tabular crystalline deposits with subround faces and rhombohedric tendency. The scanning EM provided with a X ray microanaliser enabled us to see crystalline deposits which in some fields adopt a star-shaped form corresponding to calcium crystals of not very well defined habit.
