Severe hemoptysis of pulmonary arterial origin: signs and role of multidetector row CT angiography.

Background: Hemoptysis of pulmonary arterial origin is a diagnostic challenge in patients admitted to a respiratory ICU (RICU) for treatment of hemoptysis. Its early accurate recognition and treatment reduce morbidity and prevent mortality. Multidetector row CT angiography (MDCTA) is an accurate method for imaging the systemic vascular network.

Hemoptysis complicating Scimitar Syndrome: from diagnosis to treatment.

We report the case of a 24-year-old patient with known scimitar syndrome presenting with hemoptysis. Multidetector CT angiography showed the scimitar vein draining the right lung to the inferior vena cava associated with right lower lobe bronchopulmonary sequestration. The presence of hemoptysis associated with scimitar syndrome is likely secondary to an anomalous systemic arterial blood supply.

Value of dynamic enhanced magnetic resonance imaging for distinguishing between ovarian fibroma and subserous uterine leiomyoma.

Purpose: The purpose of this study was to assess the accuracy of magnetic resonance imaging (MRI), particularly, dynamic MRI, in distinguishing ovarian fibromas from subserous uterine leiomyomas.

Material And Methods: Fifteen ovarian fibromas and 15 subserous uterine leiomyomas were retrospectively reviewed. All MR examinations included dynamic contrast-enhanced (DCE) sequences.

Role of MDCT in identification of the bleeding site and the vessels causing hemoptysis.

Objective: MDCT has improved the management of hemoptysis by providing more precise depiction of bronchial and nonbronchial systemic arteries than conventional CT. The purpose of this article is to review the role of MDCT in the identification of the bleeding site and the vessels causing hemoptysis.

Conclusion: Identification of the origin of the involved systemic arteries (bronchial and nonbronchial) or involved pulmonary artery on MDCT enables the interventional radiologist to treat them, especially in elderly patients with a tortuous aorta and atheroma.

[The TELIF network of Paris-area public hospitals (AP-HP)].

After a feasibility study, the TELIF network (neurosurgical emergencies in the Paris region) was created in November 1994. The goal was to reduce the number of patient transfers among the different hospitals, by teletransmission of computed tomography images between computers located in the emergency departments of general hospitals and the neurosurgery department. The initial goal has been reached, with a 70 % reduction in the number of patient transfers.

[Intramedullary lipomatous ependymoma: case report].

A 51 year-old man was admitted to our hospital with poor general health and neurological disturbances with paresthesia, dysuria and defecation disorder. Neuroimaging showed a syringomyelia cyst from C1 to conus medullaris, together with a intramedullar tumoral mass in T6-T7. Histological examination of the surgical specimen led to the diagnosis of lipomatous ependymoma.

[Harmonizing indications for emergency radiological examinations for adults].

Introduction: The "Collégiale des radiologistes" of the Paris public hospital system (Assistance Publique-Hôpitaux de Paris, AP-HP) has participated since 1998 in a collaborative quality improvement program for the 49 radiology departments. They work together with the AP-HP college of emergency physicians on one part of this program, which focuses on emergency radiologic work-ups. Analysis of the dysfunctions in this sector underlined the lack of agreement between clinicians and radiologists on the examinations required.

Relationship between attentional performance and corpus callosum morphometry in patients with Alzheimer's disease.

There has been considerable interest in cognitive deficits associated with Alzheimer's disease (AD) and relationships between these impairments and specific cortical atrophies. Two previous studies [Neuropsychologia 28 (1990) 1197; Dementia 3 (1992) 350] have found that AD patients exhibit significant impairments in the attentional ID/ED set-shifting tasks of the CANTAB battery which involved attentional shifting abilities. But, at present, no study has examined the neural bases of these abilities in AD patients.
