[The localized form of reflex sympathetic dystrophy-a case report.].

Introduction: The reflex sympathetic dystrophy (RSD) syndrome usually shows a distally generalized distribution pattern of symptoms. Here we report a case with a distally localized form of RSD.

Patient And Methods: In a 53-year-old woman, following a local lesion in the nail bed of the left thumb, a neuroma developed at the side of the lesion during the next half year.

[Grzybowski type eruptive keratoacanthomas and ectropion. A therapeutic problem].

Eruptive Grzybowski-type keratoacanthoma is a rare variant of multiple keratoacanthoma and is not accompanied by internal malignancies. Up to now only 16 cases of eruptive Grzybowski-type keratoacanthoma have been described in the literature. Eruptive and solitary keratoacanthomas cannot be distinguished histologically.

Time course of wound healing.

Wound healing is a special kind of inflammation. Undisturbed wound healing is subject to a fixed time schedule of biochemical and cellular events. It is virtually impossible to deal with the time course of wound healing without describing the cellular and non-cellular events involved.

[Peri-capillary fibrin cuffs--an O2 diffusion block?].

In 42 patients with a chronic venous insufficiency Stage I-III transcutaneous oxygen tension was measured above the medial ankle and the leg ulcer edges respectively at 44 degrees C. The measurement point was biopsied and evaluated immunfluorescencehistologically for pericapillary fibrin cuffs (PCF). Fibrin cuffs are associated with decreased tcpO2-tensions.

Factor XIII-deficiency in the blood of venous leg ulcer patients.

Pericapillary fibrin cuffs are probably involved in the pathogenesis of venous leg ulcers. Factor XIII (Fibrin stabilizing factor) is of importance in wound healing. Its activity, which may affect ulceration, was found to be significantly reduced in the blood of venous leg ulcer patients and in post-phlebitic patients, compared with healthy controls.
