Intraspinal metalloma causing lumbar stenosis after interbody fusion with cylindrical titanium cages.

Intraspinal metallomas are rare. The authors present a case after implantation of two titanium threaded interbody cages at the L4L5 level, without posterior instrumentation. To their knowledge this is the first case due to intervertebral cages.

[Prognostic value study of lung cancer molecular markers].

Background And Objective: The aim of this study was to determine the prognostic value of molecular markers (proteins) of different paths of lung cancer development in patients with non small cell lung carcinoma (NSCLC) in initial stages.

Material And Method: Observational, cohort study in patients with NSCLC that was initially treated surgically in our hospital between October 1993 and September 1997. Thirty-two proteins were selected.

Analysis of the molecular expression profile of non small cell lung carcinoma associated to chronic obstructive pulmonary disease.

Chronic obstructive pulmonary disease (COPD) is an independent risk factor to develop lung cancer but there are no different functional clusters of biomarkers between patients with non-small cell lung cancer (NSCLC) with or without COPD. To analyse protein expression, in order to find out whether samples of resected NSCLC from patients with COPD present a different molecular expression. Observational, cohort, concurrent study with sampling since treatment of disease in patients with NSCLC in initial stages (pIA-pIIB) treated surgically in our hospital between October 1993 and September 1997.

[Adenocarcinoma of the female urethra: report of two cases and bibliography review].

Objectives: Primary adenocarcinoma of the female urethra is a rare malignancy. We report two cases and a review of the latest articles focused on classification and treatment of this kind of neoplasm.

Methods: We present two females diagnosed of urethral adenocarcinoma, describing clinic and pathological features, diagnosis and treatment.
