[Surgical management of persistent diarrhea].

An 82-year-old patient presented with a cervical lesion and refractory diarrhea of many years' standing. Surgical therapy of a medullary thyroid carcinoma had been performed 16 years previously. Appropriate tumor follow-up had not been carried out hitherto.

Parvovirus B19 detected in Rosai-Dorfman disease in nodal and extranodal manifestations.

Sinus histiocytosis with massive lymphadenopathy (SHML), also designated as Rosai-Dorfman disease (RDD), is a rare benign reactive lymphoproliferative disorder. It is defined by a characteristic histopathology with sinus histiocytosis and haemophagocytosis known as emperipolesis. In histiocytes S100 is strongly expressed, whereas CD1a staining typically is negative.

[Nitinol stent implantation in benign esophagotracheal fistula].

The self-expanding nitinol stent is easy to handle and well tolerated. It offers an improved method in the treatment of perforations of the upper aerodigestive tract. It is easily implantable with rigid and flexible endoscopes.

[Serum concentrations of soluble adhesion molecules sICAM-1 and sVCAM-1 in patients with malignant ENT tumors].

Background: Adhesion molecules are implicated in various stages of tumor progression and metastasis. Soluble forms of intercellular adhesion molecule-1 (sICAM-1) and vascular cell adhesion molecule-1 (sVCAM-1) were recently described. The aim of this study was to determine a differences in concentration of these molecules in patients with head and neck squamous cell carcinoma (HNSCC) compared to healthy controls.

Inverse association between endogenous glucocorticoid secretion and L-selectin (CD62L) expression in trauma patients.

Exogenously administered glucocorticoids downregulate inflammatory host response, i.e. by inhibition of adhesion molecule expression on leukocyte surfaces.
