[Persistent post-occupational dermatitis: a rare variant of a common skin disease].

Persistent post-occupational dermatitis is a rare variant of occupational eczemas characterized by skin symptoms which persist after the elimination of occupational allergens. Further diagnostic criteria are the followings: absence of dermatitis in past history of patients, presentation confined to both hands almost exclusively, and causal role of occupational allergens with both irritative and allergic origins is confirmed. The author presents a case which meets all these diagnostic criteria.

[Chondrosarcoma in Mafucci's syndrome -- an interdisciplinary approach to a rare disease].

Mafucci's syndrome is a rare genetic but non-hereditary disorder, characterized by multiple enchondromas (enchondromatosis), hemangiomas and, rarely, lymphangiomas. The risk for malignant transformation of enchondromas is very high, and chondrosarcomas can develop which mainly metastatize to the lungs. A case report of a 61-years-old male, whose enchondromatosis developed at his age of 10 years, is described.

Color Doppler imaging of posttraumatic priapism before and after selective embolization.

High-flow priapism usually follows perineal or penile trauma with disruption of an intracavernosal artery. Angiographic embolization of the lacerated artery is currently considered the treatment of choice. The contribution of gray-scale and color Doppler ultrasonography (US) in diagnosis and treatment of 10 patients with high-flow priapism was investigated.

Detection of liver metastases by pulse inversion harmonic imaging during Levovist late phase: comparison with conventional ultrasound and helical CT in 160 patients.

The aim of this study was to evaluate capabilities of pulse inversion harmonic imaging (PIHI) with Levovist in detection of liver metastases compared with conventional ultrasound (US) and helical CT (HCT). One hundred sixty consecutive patients with known malignancies were evaluated by conventional US, PIHI 2 min (40 patients) or 4 min (120 patients) after Levovist injection and HCT. Conspicuity and number of the identified metastatic lesions were evaluated and assessed by statistical analysis (significance p<0.

Characterization of focal hepatic lesions in cirrhotic patients by Pulse Inversion Harmonic Imaging US contrast specific technique with Levovist.

Purpose: To evaluate the capabilities of Pulse Inversion Harmonic Imaging (PIHI) with hepatospecific US contrast agent Levovist in the characterization of focal liver lesions in cirrhotic patients.

Materials And Methods: Thirty-nine focal hepatic lesions in 25 consecutive cirrhotic patients identified by conventional ultrasound (US), were evaluated by color Doppler (CD), power Doppler (PD) with spectral analysis of tumoural vessels and PIHI. PIHI was performed 30 seconds (vascular phase) and 3-5 minutes (late phase) after Levovist injection.
