Objective: The aim of the study was to hihglight the benefits and safety of the endoscopic transsphenoidal pituitary gland tumor surgery.

Background: The endoscopic transsphenoidal approach to the Turkish sella minimizes traumatization of nasal cavity structures, allows direct access to the tumor and intra, para and suprasellar views (13).

Methods: The surgical procedure was described.

Temporal variation of trace elements in waters polluted by municipal solid waste landfill leachate.

Landfill leachate-polluted stream waters were monitored in three sampling campaigns (November 2001 to June 2006), with emphasis on trace elements. The data were evaluated by means of statistics and speciation modelling. Two statistically different groups of trace elements were distinguished: (1) Ba, Sr, Al, Fe, Mn, Cr, Co, Ni, V, As, Se, Sb, U, Li, Rb and Cs decrease during the rain event due to dilution; (2) Pb, Zn, Cu and Cd increase during the rain event due to the dissolution of hydrous ferric oxides and calcite, on whose surfaces these elements are bound, mainly in the stream sediments downgradient to the landfill.

Some new results of investigation of tuberous sclerosis.

The authors describe the case of a patient with tuberous sclerosis. The occurrence of M-protein with antigenous appurtenance of IgM not only in the patient himself but also in some of the healthy blood relations in the family is pointed out. The question of clinical and biochemical-immunological peculiarities occurring in connection with this disease is discussed.
