Lumbar muscle involvement in the occurrence of osteoporotic vertebral fracture.

Objective: To determine if a lumbar musculature deficiency (paravertebral - PVM - and psoas - PM - muscles) is associated with a higher prevalence of vertebral fractures in osteoporotic patients.

Methods: To constitute the fracture group, data were collected retrospectively from patients with one or more recent osteoporotic vertebral fractures between T10 and L5 such as non-injected computerized tomography (CT), dual-energy X-ray absorptiometry (DXA). A control group was made by matching the patients on age, bone mineral density measured by DXA and gender.

Is systematic Gadolinium injection relevant during MRI follow-up for non-functioning pituitary macroadenomas?

Objective: To compare the performance of coronal contrast-enhanced T1-weighted (ceT1-w) and T2-weighted (T2-w) sequences for diagnosing progression during the MRI follow-up of Non-Functioning Pituitary MacroAdenomas (NFPMAs).

Patients And Methods: 106 patients, who had at least two MRIs for the follow-up of NFPMA, were enrolled retrospectively. The largest adenoma diameter was measured on coronal ceT1-w sequences and separately on T2-w sequences for all follow-up MRIs.

PET metabolic tumor volume as a new prognostic factor in childhood rhabdomyosarcoma.

Purpose: Childhood RMS is a rare malignant disease in which evaluation of tumour spread at diagnosis is essential for therapeutic management. F-18 FDG-PET imaging is currently used for initial RMS disease staging.

Materials And Methods: This multicentre retrospective study in six French university hospitals was designed to analyse the prognostic accuracy of MTV at diagnosis for patients with RMS between 1 January 2007 and 31 October 2017, for overall (OS) and progression-free survival (PFS).

The accuracy of MRI for the diagnosis of ramp lesions.

Objectives: To assess the diagnostic accuracy of MRI in diagnosing ramp lesions in patients with an acute lesion of the anterior cruciate ligament (ACL).

Materials And Methods: All consecutive patients over 15 years of age who underwent surgical repair of the ACL at a single hospital between January and May 2019, with MRI data available, were included in this retrospective study, except patients who had previous knee surgery. The gold standard was arthroscopic evaluation.

Significant response to immune therapies in a case of subacute necrotizing myopathy and FKRP mutations.

Necrotizing myopathies can be encountered in various conditions as acquired myopathies (toxic or autoimmune) or muscular dystrophies. We report a twenty-year-old Caucasian woman who presented with clinical findings suggestive of an inflammatory myopathy: subacute onset of lower limb muscle weakness, myalgia, weight loss and absence of family history. The serum creatine kinase level was elevated at 4738 IU/L (normal range, 25-175 IU/L).

[Ma2 antibody and multiple mononeuropathies].

Anti-Ma2 antibodies belong to a family of onconeuronal antibodies that target proteins expressed in brain, testis and several tumors. Previously observed in patients presenting with limbic encephalitis, they seem to be associated with several other paraneoplastic syndromes. We report the case of a 73-year-old woman presenting sensory and motor neuropathy associated with non-small-cell lung cancer who had Ma2-antibodies.

Asymmetric metabolic profile in mesial temporal lobes: localized H-1 MR spectroscopy in healthy right-handed and non-right-handed subjects.

Purpose: To determine a possible asymmetric metabolic profile in right- handed and non-right-handed healthy subjects by comparing proton spectra from temporal lobes.

Materials And Methods: Twenty-eight healthy adults (17 right-handers, 11 non-right-handers) underwent magnetic resonance (MR) imaging and single-voxel MR spectroscopy. N-acetylaspartate (NAA), choline (Cho), and creatine (Cr) peak areas were measured.

[Value of gadolinium magnetic resonance imaging of the lumbosacral roots in acute polyradiculoneuritis].

Four patients with acute inflammatory polyradiculoneuropathy were evaluated with MRI. In 3 of 4 cases, gadolinium enhancement was observed in the nerve roots of cauda equina, on frontal and horizontal slices. This enhancement was correlated with the severity of the clinical picture and the cerebrospinal-fluid inflammatory protein concentration and supports the inflammatory nature of this forms of acute polyradiculoneuropathy.

Late thalamic atrophy in infarction of the middle cerebral artery territory in neonates. A prospective clinical and radiological study in four children.

We report four cases of progressive thalamic atrophy following ipsilateral cerebral infarction in the territory of the middle cerebral artery in neonates, with prospective radiological and clinical follow-up. This type of atrophy appears within 6 months after the onset of cerebral infarction. In the short term, this atrophy has no action on sensory and memory function and/or on sensory evoked potentials.

Risk factors for primary cerebral hemorrhage: a population-based study--the Stroke Registry of Dijon.

Risk factors for primary cerebral hemorrhage remain uncertain. The population-based Stroke Registry of Dijon provides data on the risk factors. Among residents of Dijon (France), 130 cases of primary cerebral hemorrhage hospitalized from 1985 to 1992 were matched with 130 controls by age and sex.

Preliminary observations of metabolic characterization of bilateral temporal epileptic focus, using proton magnetic resonance spectroscopy. Three cases.

The authors report the case of 3 patients with bilateral temporal lobe epilepsy demonstrated by EEG and sphenoïdal electrodes. Two out of the 3 patients presented with childhood febrile convulsions. Their neurological and mental examination was normal.

[Prevalence and prognostic value of transient ischemic complication preceding cerebral infarction].

To evaluate the prevalence, the aetiological profile and the neurological consequences at day 15 of a transient ischaemic attack (TIA) before a cerebral infarction, we undertook survey from 1985 to 1991, on 1,149 cases with cerebral infarction observed on the population of Dijon. On 1,149 cases, 275 (24%) were preceded by a TIA. Fifty seven cases were lacunar infarcts (20.

Early seizures after acute stroke: a study of 1,640 cases.

We evaluated prospectively the occurrence of seizures within 15 days of a first stroke or transient ischemic episode in 1,640 patients to study relation between seizures and type of stroke. Seizures occurred in 90 patients (5.4%), including 36 (4.

[Gyratory epileptic seizures. Radioclinical correlations].

The authors report 3 cases of gyratory seizures whose epileptic nature was demonstrated on the following features. They appeared with a loss of consciousness. In 2 cases, they ended with a tonic-clonic generalized fit and in the 3 cases, they were mixed with other generalized seizures.

Homolateral ataxia and crural paresis: a crossed cerebral-cerebellar diaschisis.

A patient developed weakness of the right leg and homolateral ataxia of the arm, caused by a subcortical infarct in the area supplied by the anterior cerebral artery in the left paracentral region, demonstrated by CT and MRI. Cerebral blood flow studied by technetium-labelled hexamethyl-propylene-amine oxime using single photon emission computed tomography showed decreased blood flow in the left lateral frontal cortex and in the right cerebellar hemisphere ("crossed cerebral-cerebellar diaschisis"). The homolateral ataxia of the arm may be caused by decreased function of the right cerebellar hemisphere, because of a lesion of the corticopontine-cerebellar tracts, whereas crural hemiparesis is caused by a lesion of the upper part of the corona radiata.

So-called generalized epilepsy in children leading to frontal epilepsy with a frontal syndrome in adulthood: a clinical, EEG and radiological study of 10 cases.

The authors report 10 cases of epileptic patients with the onset in childhood of the clinical and EEG features of cryptogenic generalized epilepsy which evolved into frontal epilepsy, confirmed by the clinical and EEG features and was associated with a frontal syndrome. CT-scan and MRI showed mild atrophy in the frontal area, while SPECT showed a decrease in the frontal blood flow in 70% of the cases. The authors consider that frontal epilepsy may mimic generalized epilepsy.

[Transient neurologic deficit preceding intracerebral hemorrhage. Physiopathological hypotheses].

Seventeen out of 238 cases (7%) of intracerebral hemorrhage were preceded by transient neurological deficit. In two cases, intracerebral hemorrhage and transient neurological deficit were thought to be due to amyloid angiopathy, this diagnosis was confirmed at autopsy in one case. In one case, intracerebral hemorrhage and transient neurological deficit were due to a cavernoma.
