Neutrophilic and eosinophilic dermatitis caused by contact allergic reaction to paraphenylenediamine in hair dye.

Background: Paraphenylenediamine (PPD) in hair dyes can cause systemic as well as cutaneous allergic reactions such as neutrophilic and eosinophilic dermatitis. The symptoms are often severe. The acute lesion is normally histologically indistinguishable from any eczematous reaction with marked spongiosis.

Differential expression of tissue factor (TF) in calcineurin inhibitor-induced nephrotoxicity and rejection--implications for development of a possible diagnostic marker.

Deposition of fibrin in the form of fibrinoid necrosis is a common feature of severe acute renal allograft rejection. The role of the coagulation system and its initiator tissue factor (TF) during this process is, however, still poorly understood. In this study, we analyzed the expression of TF in 88 renal transplants afflicted with different forms of rejection and calcineurin inhibitor-induced nephrotoxicity, to see whether there was differential expression of this protein.

Skin ulcerations as manifestation of vasculopathy in neurofibromatosis.

Vascular involvement in neurofibromatosis sometimes occurs and usually affects larger blood vessels of internal organs. We describe an unusual case of a now 41-year-old man with extensive skin involvement with ulcerations and histopathologic features of fibromuscular dysplasia, which has not been previously reported in the skin.

Does mesh implantation affect the spermatic cord structures after inguinal hernia surgery? An experimental study in rats.

Background: Inguinal hernia repair is the most common operation in general surgery. Prosthetic reinforcement of the inguinal area with polypropylene mesh has increased dramatically in the last decade. The aim of this study was to evaluate how different types of mesh affect the spermatic cord structures.

[Results of morphologic epidemiologic study of coronary arteries in Kaunas population aged 20-69 years: atherosclerotic lesions and their interrelationship].

Objective: The object of study was the type, frequency and extent, as well as correlation of atherosclerotic lesions in Kaunas population aged 20-69 years.

Results: The frequency and intimal area of raised atherosclerotic lesions (fibrous and complicated plaque and calcinosis) are age-dependent. The increase of raised lesions area seems to alter at different decades of life.
