The use of transtelephonic loop recorders for the assessment of symptoms and arrhythmia recurrence after radiofrequency catheter ablation.

Radiofrequency catheter ablation (RFA) is an effective treatment of arrhythmias. However, patients often remain symptomatic after the procedure. We aimed to assess the arrhythmia recurrence after successful RFA in relation to patients' symptoms using transtelephonic loop recorders.

Abdominal metastases from lung cancer resulting in small bowel perforation: report of three cases.

Metastatic lung cancer to the small bowel is a rare occurrence. Acute complications such as perforation, hemorrhage and obstruction are even rarer. We present 3 cases of small bowel perforation from metastatic lung cancer.

Computer-based malignancy grading of astrocytomas employing a support vector machine classifier, the WHO grading system and the regular hematoxylin-eosin diagnostic staining procedure.

Objective: To investigate and develop an automated technique for astrocytoma malignancy grading compatible with the clinical routine.

Study Design: One hundred forty biopsies of astrocytomas were collected from 2 hospitals. The degree of tumor malignancy was defined as low or high according to the World Health Organization grading system.
