The role of bronchial biopsy in the prediction of response to biological therapy in severe uncontrolled asthma: a prospective study.

Background: Up to two thirds of patients with severe uncontrolled asthma (SUA) who received biological therapy do not have a complete response.

Research Question: Can bronchial biopsy (BB) play a role in the identification of patients with SUA who has a better response to biological therapy?

Study Design: AND METHODS: Prospective multicentre study. Consecutive SUA patients candidate to biological therapy underwent bronchoscopy and BB prior to biological therapy and clinical response was evaluated 6 months later.

Quantitative analysis of MGMT promoter methylation status changes by pyrosequencing in recurrent glioblastoma.

MGMT promoter methylation status can change in response to several factors, treatment with alkylating therapy being the mechanism more commonly cited in the literature. Some authors have attempted to quantify these alterations, with inconsistent results. This study aims to determine changes in MGMT promoter methylation status by pyrosequencing, which quantitatively yields results, in a cohort of patients reoperated for recurrent glioblastoma and having previously completed the Stupp protocol.

Evaluation of cervical dysplasia treatment by large loop excision of the transformation zone (LLETZ). Does completeness of excision determine outcome?

Objectives: To evaluate the therapeutic and diagnostic potential of large loop excision of the transformation zone (LLETZ) in the management of cervical dysplasia (CD) when colposcopy is satisfactory; to determine if there is a relationship between completeness of excision and outcome.

Study Design: Ninety loop diathermies performed in the management of CD were studied prospectively.

Results: Eighty (88.
