Subpopulations of natural killer-T-like cells before and after surgical treatment of laryngeal cancer.

Introduction: Tumours connected with head and neck comprise about 5% of all tumours. The most frequent histological type of laryngeal carcinoma is squamous cell carcinoma. Different research projects suggest that the role of T lymphocytes might be significant in tumour development.

The percentage of iNKT cells among other immune cells at various clinical stages of laryngeal cancer.

Introduction: Invariant natural killer T (iNKT) cells constitute a small population of immune cells that share functional and phenotypic characteristics of T lymphocytes and NK cells. Due to their involvement in specific and non-specific immune responses, iNKT cells may represent an important component of antitumor and anti-infectious immunity.

Material And Methods: Using flow cytometry, we analyzed the percentages of iNKT cells as well as T and B lymphocytes in peripheral blood of 50 laryngeal cancer patients at various clinical stages in comparison to healthy controls (n=15).

[Biological treatment in severe Still's disease--a case report].

Still's disease and systemic juvenile idiopathic arthritis (JIA) are multisystem inflammatory diseases of unknown etiology, different disease course and prognosis. Still's disease is characterized by hectic fever, arthritis, skin rash, organomegaly, elevated serum ferritin and inflammatory factors. Early diagnosis and intensive treatment can prevent disease progression and reduce complications such as amyloidosis, physical disability.

Target Therapy in Hematological Malignances: New Monoclonal Antibodies.

Apart from radio- and chemotherapy, monoclonal antibodies (MoAbs) represent a new, more selective tool in the treatment of hematological malignancies. MoAbs bind with the specific antigens of the tumors. This interaction is a basis for targeted therapies which exhibit few side effects and significant antitumor activity.

Onyx(®) in endovascular treatment of cerebral arteriovenous malformations - a review.

Arteriovenous malformation (AVM) is an abnormal connection between arteries and veins, bypassing the capillary system. In most cases, the disorder may be asymptomatic. The objective of endovascular AVM treatment is set individually for each case upon consultations with a neurosurgeon and a neurologist.

Epstein-Barr virus-associated lymphoproliferative disorders.

The Epstein-Barr virus (EBV) is one of the most common human viruses, infecting more than 90% of the world's adult population. In some individuals the interplay between EBV replication, latency and immune control can be disrupted and evokes prolonged proliferation of EBV-infected lymphocytes and their malignant transformation. Since its discovery as the first human tumor virus, EBV has been implicated in the development of a wide range of human cancers.
