摘要:

AbstractBackground. The ultrastructure of different fungi have been described in recent literature; however, few reports have concerned dermatophytes.Methods. Fine structure ofTrichophyton violaceumwas observed using electron microscopy.Results. Hyphae appeared as branched segmented filaments with a cell wall consisting of two layers. Thin electron dense plasma membrane was evident continuous with the inner surface of the cell wall. Septal walls with central pores and a uniform electron opacity plugs were seen. The hyphae were multinucleated and the cytoplasm contained endoplasmic reticulum, mitochondria, and vacuoles.Conclusions. Although these findings showed ultrastructural similarities of the cell wall withMicrosporum canis, Microsporum gypseumandMicrosporum audouinii, there were some points of difference in the ultrastructure of the hyphae inEpidermophyton floccosum, and in the mitochondria ofTrichophyton mentagrophytesas described by other investigators.

摘要:

AbstractBackground. Pemphigus is a vesiculobullous autoimmune disease characterized by acantholysis due to antibodies against epidermal antigens.Case Reports. We report the first two cases of pemphigus in which lesions appeared in areas traumatized by cosmetic procedures. In one case, the patient had a history of pemphigus under excellent control; pemphigus lesions appeared only in her surgical scars 2 months after a reduction mammoplasty and facelift. The other patient presented with an outbreak of pemphigus 4 weeks after a chemical peel.Conclusions. Physical agents including infrared and ionizing radiation as well as ultraviolet light are known triggers of pemphigus. We suggest that cosmetic procedures can initiate pemphigus and that this change must be differentiated from postoperative wound infections and other reasons for poor wound healing.

摘要:

AbstractBackground. The occurrence of multiple Bowen's disease (bd) in skin away from the anogenital area is rare. In contrast, multiple lesions ofbdinvolving the anogenital skin (bowenoid papulosis) are not so rare and have been found to associated with human papilloma virus (hpv) usually type 16. We encountered a patient with multiple BD of the fingers and endeavored to detecthpvin his lesions.Methods. Separatebdlesions from 3 fingers of the patient were investigated for the presence ofhpvby means of the polymerase chain reaction, followed by dot blot hybridization. Other cases ofbdwith coexistent HPV infection excluding the anogenital area were collected from the literature for comparative study.Resultshpvtype 16 was detected in each of the three finger lesions ofbd. Twenty cases ofhpvrelatedbdinvolving sites other than the anogenital area were found in the literature. Three of these cases had multiple lesions.Conclusions. Review of the 4 cases with multiplehpvrelated nonanogenitalbdand the 17 others with solitary lesions reveals predilection for the hands and feet (90%) and affinity for type 16 infection (81%). The lesions usually present as verrucous plaques.

摘要:

AbstractBackground. Erythema nodosum (en) is usually considered to be a septal panniculitis, and nodular vasculitis (nv) a lobular panniculitis. We tested the usefulness of this histologic classification in clarifying a frequent clinical dilemma:enversusnv.Methods. Over 3 years 109 patients with panniculitis were included in this study. After a history and a physical examination, a clinical diagnosis was made according to well‐established criteria.Results. From the study of 88 patients, we concluded that in the clinically typical cases, the clinico‐pathologic agreement was 93% and 94% forenandnvrespectively, whereas it diminished to 79%, 72%, and 67% in the cases clinically diagnosed asenmigrans, atypicalen, and atypicalnv, respectively. Moreover, septal and lobular panniculitis were always two clear‐cut, different, opposite patterns of hypodermal inflammation to these conditions.Conclusions. In the absence of a known pathogenetic mechanism, the histopathology remains the most objective discriminating marker betweenenandnv, mainly in the clinically atypical and doubtful

摘要:

AbstractBackground. An epidemic of cercarial dermatitis caused bySchistosoma spindalecercaria occurred in November 1988 in a district called Chaiya, Surajthani province, in Southern Thailand.Case Reports. Fifty‐eight Thai farmers in Chaiya, Surajthani gave a history of itch following immersion in water while planting rice. The area of rice field was flooded for 10 days before farmers started working. The duration of the disease ranged from 2 days to 1 month. Forty‐one patients had the disease for the first time, seventeen had a history of previous manifestations.Conclusions. This epidemic was caused byS. spindalecercaria, which developed in theIndoplanorbis exustussnail, associated with flood
