Delirium After Surgery for Proximal Femoral Fractures in the Frail Elderly Patient: Risk Factors and Clinical Outcomes.

Purpose: The primary aim of this study was to identify risk factors for delirium after hip fracture surgery. The secondary purpose of this study was to verify peri-operative clinical outcomes, adverse events and mortality rates in delirium patients after hip fracture surgery.

Patients And Methods: A prospective hip fracture database was used to obtain data.

[Experience with the surgical management of primary and secondary chondrosarcoma].

Forty eight primary and 20 secondary chondrosarcomas were treated surgically 1975 through 1991. An evaluation of the data of the Bone Tumor Register of the Semmelweis Medical University proved that the incidence of the malignant transformation and development of secondary chondrosarcomas is 3% and 2.6% among solitary osteochondromas.

[Determination of thiocarbamide and related derivatives using an S-alkylation reaction].

S-alkylation reaction based on the Hantzsch synthesis followed by cyclization and aromatization reactions were used to develop an analytical procedure. The various thiocarbamide derivatives were transformed to substituted aminothiazol by using suitable alpha-halogenoketones as the reagents. At the end of the reaction the reaction products are present as 2-aminothiazol salts.

Comparison of the polymorphic modifications of famotidine.

The polymorphic modifications of famotidine are described and characterized by their spectroscopic (infrared, X-ray) and some physico-chemical data. In addition to the standard physico-chemical data (melting point, solubility, bulk density) some further properties influencing its use in pharmaceutical technology are also characterized. The methods used to prepare the morphologically homogeneous modifications are also given.
