Brain structural and functional changes during menstrual migraine: Relationships with pain.

Objectives: Menstrual migraine (MM) is a special type of migraine associated with the ovarian cycle, which imposes a marked burden on female patients. However, the pathogenesis of MM is not completely understood. We investigated gray matter volume (GMV) and functional connectivity (FC) alterations in patients with MM to explore whether there are changes in resting-state FC (rsFC) in brain regions with structural GMV abnormalities and investigated their relevance to pain and concomitant symptoms.

Effect of puncture sites on pneumothorax after lung CT-guided biopsy.

To determine the influence of puncture site on aspiration in dealing with pneumothorax following CT-guided lung biopsy.Two hundred thirty-six pneumothorax patients after CT guided lung biopsies were retrospective analyzed from January 2013 to December 2018. Patients with minor asymptomatic pneumothorax were treated conservatively with monitoring of vital signs and follow-up CT to confirm stability.

Application of side-hole catheter technique for transradial arterial chemoembolization in patients with hepatocellular carcinoma.

Purpose: The purpose of this study was to retrospectively evaluate the efficacy and safety of side-hole catheter technique for transarterial chemoembolization (TACE) via transradial artery access (TRA) in patients with hepatocellular carcinoma.

Materials And Methods: From November 2015 to August 2017, a total of 1040 TACE procedures were performed via TRA for hepatocellular carcinoma. In 10 (1%) of these 1040 TACE procedures via TRA, conventional microcatheter technique (CMT) failed and side-hole catheter technique was attempted.

Manual aspiration in the biopsy-side down position to deal with delayed pneumothorax after lung biopsy.

Background: To assess the effect of aspiration in the biopsy-side down position to deal with delayed pneumothorax after computed tomography (CT)-guided lung biopsy.

Methods: A retrospective review was performed of the 236 delayed pneumothorax patients who underwent CT-guided transthoracic needle biopsies (TTNBs). Asymptomatic minimal pneumothorax patients were managed conservatively.

Dynamic contrast-enhanced MRI for the assessment of spinal tumor vascularity: correlation with angiography.

Purpose: To determine if dynamic contrast-enhanced MRI (DCE-MRI) could correlate well with invasive angiography in the characterization of spinal tumor vascularity.

Methods: Totally 40 patients with untreated spinal tumors underwent MRI before preoperative angiography and embolization. Tumors were assigned to hypervascular, moderate, or hypovascular groups based on angiographic appearance.

[Study on the epidemiology and risk factors on dysphagia after ischemic stroke in Chengdu City, China].

Objective: To study the incidence and the risk factors of dysphagia after ischemic stroke in Chengdu City, China.

Methods: Review was made with unified questionnaire on dysphagia after ischemic stroke in 563 patients from four hospitals, from January to December 2005. Over 20 risk factors related to dysphagia after ischemic stroke were analyzed by logistic regression.
