Spontaneous rupture or avulsion of the vagina from the cervix during labour is a rare condition. The term colporrhexis describes this obstetric injury and it is subdi­ vided into primary or secondary, spontaneous or traumatic, complete or incomplete. Incomplete colporrhexis includes rupture of the vaginal epithelium and the muscularis, whereas complete involves the overlying peritoneum as well....

Spinal metastases (SMs) from thyroid cancers significantly reduce the quality of life by causing pain and neurological deficits and increase mortality. Complete surgical resection of isolated thyroid SMs is a promising treatment option; however, the postoperative outcome is unknown. This study aimed to compare the postoperative courses of patients undergoing complete resection of thyroid SMs wi...

BACKGROUND Over the last years, evidence has accumulated in support of bracing as an effective treatment option in patients with idiopathic scoliosis. Yet, little information is available on the impact of compliance on the outcome of conservative treatment in scoliotic subjects. The aim of the present study was to prospectively evaluate the association between compliance to brace treatment and ...

BACKGROUND AND PURPOSE Some cerebral aneurysms that have been coiled reopen over time and additional treatment should be considered to reduce the risk of recurrent hemorrhage. Our purpose was to assess procedural complications and angiographic results of additional coiling in patients with previously coiled but reopened aneurysms and to evaluate protection against (re)bleeding. METHODS We com...

BACKGROUND AND OBJECTIVE endoscopic polypectomy may allow curative resection of invasive adenocarcinoma on colorectal adenoma. Our goal was to determine the factors associated with complete endoscopic resection of invasive adenocarcinoma. METHODS retrospective observational study. We included 151 patients with invasive adenocarcinoma on adenomas endoscopically resected between 1999 and 2009. ...

Diastolic dysfunction indicates a functional abnormality of diastolic relaxation, filling, or distensibility of the left ventricle (LV), regardless of whether the LVEF is normal or abnormal. Diastolic dysfunction is practically always progressive and connected with higher morbidity and mortality rates, and, if not treated may lead to a diastolic heart failure. The golden standard for evaluation...

BACKGROUND Recent data suggest that octogenarians' long-term survival after complete coronary artery bypass graft revascularization is superior to incomplete revascularization. Discriminating between variable definitions of "complete" complicates interpretation of survival data. We aimed to clarify octogenarian long-term survival rates by stratifying revascularization subtypes. METHODS AND RE...

A new preconditioner for symmetric positive definite systems is proposed, analyzed, and tested. The preconditioner, compressed incomplete modified Gram–Schmidt (CIMGS), is based on an incomplete orthogonal factorization. CIMGS is robust both theoretically and empirically, existing (in exact arithmetic) for any full rank matrix. Numerically it is more robust than an incomplete Cholesky factoriza...
