Minimally invasive colectomies can be performed with similar outcomes to open counterparts for colorectal cancer emergencies: a propensity score matching analysis utilizing ACS-NSQIP.

Purpose: The safety and feasibility of minimally invasive surgery (MIS) in the setting of colorectal cancer emergencies have been debated. We sought to compare postoperative outcomes of MIS with open techniques in the setting of colorectal cancer emergencies from the American College of Surgeons National Surgical Quality Improvement Program (ACS-NSQIP) database.

Methods: We included patients undergoing colectomy for colorectal cancer emergency between 2012 and 2019 "2012-2019" from the ACS-NSQIP dataset.

Impact of reduced-intensity conditioning allogeneic stem cell transplantation on women's fertility.

Introduction: Available data on women fertility for younger patients treated using RIC Allo-SCT are still limited. We evaluated ovarian function and fertility among female patients younger than 35 years who received RIC Allo-SCT for hematological malignancy or aplastic anemia (AA).

Patients And Methods: Information on therapies before RIC Allo-SCT were collected.

Intra-arterial thrombus visualized on T2* gradient echo imaging in acute ischemic stroke.

Background: MR signal loss related to arterial thrombosis leading to vascular susceptibility artifacts (VSA) has recently been reported on gradient echo images. The time course and sensitivity of VSA in acute stroke patients has been scarcely investigated. The aim of this study was to assess the frequency and course of VSA in acute stroke patients, to compare its sensitivity to distinct features of arterial occlusion as detected on FLAIR images or on CT scan.

[Rhinocerebral mucormycosis].

We report a case of a rhinocerebral mucormycosis with extensive cavernous sinus thrombophlebitis and internal carotid artery thrombosis. This case illustrates the usual clinical and imaging features of the disease, which is a potentially devastating infection in immunocompromised patients.

The stroke syndrome of cortical vein thrombosis.

Cortical vein thrombosis without sinus involvement is rarely diagnosed, although it may commonly be overlooked. We report four cases of cerebral venous thrombosis limited to the cortical veins. The diagnosis was made on surgical intervention in one patient and by angiography in three patients.

[GM2-Gangliosidosis variant B1 disclosed during adolescence by an isolated multi-systemic involvement of the central and peripheral nervous systems].

The authors report on a Portuguese family with 3 adult brothers affected with GM2-gangliosidosis (B1 variant) in a sibship of 4, and more specifically on one of these brothers with neurological onset at the age of 17. Psychosis, lower motoneuron involvement and dysarthria were predominant in two of the cases; the third had a cerebellar symptomatology. Hexosaminidase A activity, studied in leukocytes, was profoundly deficient when measured using the specific sulfated substrate, but nearly normal using a conventional assay (non-sulfated substrate).

MR imaging of head and neck vascular malformations.

Between 1980 and 1990, 150 patients with cervicofacial vascular malformations were studied at the authors' institution with computed tomography, plain radiography, and angiography. Since 1989, 34 of these patients have also undergone magnetic resonance (MR) imaging. Capillary-venous hemangiomas seem to be the best indication for the adjunctive use of MR imaging.

MRI in spontaneous dissection of vertebral and carotid arteries. 15 cases studied at 0.5 tesla.

Fifteen patients were observed between 1987 and 1990: there were six with angiographically confirmed vertebral artery dissection, and 9 with carotid artery dissection. Results showed concordance of MRI and angiographic findings, in all cases but one. The dissected portion consistently showed a semilunar hyperintensity narrowing the residual eccentric signal void of the lumen when the artery was not completely occluded.

MRI in multiple vascular lesions: identification of the ruptured malformation.

4 patients were recently admitted for subarachnoid haemorrhage with multiple vascular lesions. 3 of them presented with multiple aneurysms, and one with an aneurysm associated with an arteriovenous malformation. In these 4 cases identification of the ruptured lesion was difficult in spite of clinical examination, CT scan, and complete panangiography; on magnetic resonance imaging (MRI) was found a signal hyperintensity, mainly on T2 weighted views, corresponding to blood clots around the ruptured aneurysm.

Vertebral hemangiomas: fat content as a sign of aggressiveness.

Thirty-two vertebral hemangiomas (VHs) were evaluated with nonenhanced computed tomography (CT), T1-weighted magnetic resonance (MR) imaging, CT enhanced with contrast material, and selective spinal arteriography. The stroma between the osseous trabeculae was found to correspond to either fatty tissue or soft tissue or both. All 11 asymptomatic VHs showed complete fatty stroma at CT and increased signal intensity at MR imaging.

[An MRI study of the cervical segment of the vertebral artery].

MRI appears to be a very valuable examination to study pathology of the vertebral artery. The examination must include T1 and T2 sequences and scans in three planes. The use of oblique scans allows the planes of section to be adjusted to the course of the artery.

Spinal dural arteriovenous malformations with perimedullary drainage. Indications and results of surgery in 30 cases.

70 patients were treated for spinal dural arteriovenous fistula in the same centre, during a period of 10 years. Conus medullaris and cauda equina syndromes were observed in all patients as the clinical stereotyped presentation. Diagnosis was based on myelography in the first instance and then on angiography.

MR imaging of spinal cord arteriovenous malformations at 0.5 T: study of 34 cases.

Thirty-four patients with angiographically proved arteriovenous malformations of the spinal cord were studied between May 1986 and July 1987. Examinations were performed on a CGR 5000 Magniscan 0.5-T scanner with a surface coil in all cases, and multislices in both T1- and T2-weighted sequences were obtained in sagittal and axial planes.
