[Double second branchial cleft anomaly].
2009
Second branchial cleft anomalies are the most common of this type of neck masses. They can be classified in four types (Bailey/Proctor classification) according to their location. Type II is the most common, and related to vital neck structures such as the carotid artery and jugular vein. Cysts are the most frequent among them. Management consists of surgical excision of the cyst and tract by cervicotomy to avoid recurrence. We present an extremely rare case of a 32-year-old male who presented a sudden appearance of a right lateral neck mass that was identified by an image study as a double branchial cleft cyst. A review of simultaneous branchial cleft cyst in the literature is also made.
Microalbuminuria, renal dysfunction and cardiovascular complication in essential hypertension
1996
To evaluate the prevalence of microalbuminuria (albumin excretion rate, AER) in a wide hypertensive population, and to evaluate any relationship with cardiovascular damage and renal dysfunction.A transversal study.In 383 hospitalized Caucasian essential hypertensives (198 men, 185 women) of mean age 44 +/- 0.5 years and mean clinic blood pressure 170.3 +/- 0.95/ 103.4 +/- 0.47 mmHg, metabolic parameters, serum creatinine level (Cs), creatinine clearance rate (Ccs), 24 AER and plasma renin activity (PRA) were measured. Furthermore, each patient underwent 24 h ambulatory blood pressure monitoring (ABPM) and echocardiography to measure left ventricular mass, which was indexed both by body surf…
Inter-hemispheric remapping between arm proprioception and vision of the hand is disrupted by single pulse TMS on the left parietal cortex.
2013
International audience; Parietal cortical areas are involved in sensori-motor transformations for their respective contralateral hemifield/body. When arms of the subjects are crossed while their gaze is fixed straight ahead, vision of the hand is processed by the hemisphere ipsilateral to the arm position and proprioception of the arm by the contralateral hemisphere. It induces interhemispheric transfer and remapping. Our objective was to investigate whether a single pulse TMS applied to the left parietal cortical area would disturb interhemispheric remapping in a similar case, and would increase a simple reaction time (RT) with respect to a control single pulse TMS applied to the frontal c…
Standardized T2* map of normal human heart in vivo to correct T2* segmental artefacts.
2007
A segmental, multislice, multi-echo T2* MRI approach could be useful in heart iron-overloaded patients to account for heterogeneous iron distribution, demonstrated by histological studies. However, segmental T2* assessment in heart can be affected by the presence of geometrical and susceptibility artefacts, which can act on different segments in different ways. The aim of this study was to assess T2* value distribution in the left ventricle and to develop a correction procedure to compensate for artefactual variations in segmental analysis. MRI was performed in four groups of 22 subjects each: healthy subjects (I), controls (II) (thalassemia intermedia patients without iron overload), thala…
Reduced right atrial contractile force in patients with left ventricular diastolic dysfunction: A study in human atrial fibers—contractile force and …
2017
Summary Background/Objective The aim of our study was to evaluate right heart contractile force in patients with diastolic dysfunction (DD) with preserved left heart ejection fraction undergoing cardiac surgery. We examined the contractile properties of skinned human fibers obtained from the right auricle in two groups (DD and controls). Methods Right atrial tissue from 64 patients, who were undergoing cardiac surgery, were collected before extracorporal circulation. Tissue was conserved and prepared as "skinned fibers". We exposed the dissected fibers to increasing calcium concentrations and recorded the force values. Results Patients with DD develop significantly less force at middle and …
Glucose insulin potassium infusion improves systolic function in patients with chronic ischemic cardiomyopathy
2002
Objective: We assessed the effects of glucose–insulin–potassium (GIK) by echocardiography in stable patients with ischemic dysfunction. Methods: Twelve male patients with stable coronary disease (SCD) and ejection fraction (EF) <45% were studied for systolic function. GIK (glucose 30%, 300 insulin units and KCl 6 g/l) was infused at 1 ml/kg per h over 20 min. Hemodynamic and echocardiographic measurements were recorded at rest (T0), at the end (20 min) of GIK infusion (T + 20), 20 and 40 min after the end of the infusion (T + 40 and T + 60). Results: At T + 20, a significant decrease in WMSI (wall motion score index) was observed compared with T0 (2.16±0.14 vs. 2.30±0.16: P<0.05). An increa…
Recognition memory and prefrontal cortex: Dissociating recollection and familiarity processes using rTMS
2008
Recognition memory can be supported by both the assessment of the familiarity of an item and by the recollection of the context in which an item was encountered. The neural substrates of these memory processes are controversial. To address these issues we applied repetitive transcranial magnetic stimulation (rTMS) over the right and left dorsolateral prefrontal cortex (DLPFC) of healthy subjects performing a remember/know task. rTMS disrupted familiarity judgments when applied before encoding of stimuli over both right and left DLPFC. rTMS disrupted recollection when applied before encoding of stimuli over the right DLPFC. These findings suggest that the DLPFC plays a critical role in recog…
Nasal airway in cleft-palate patients: acoustic rhinometric data
1997
The objective of this study was to investigate an instrumental assessment technique for acquiring reproducible, metric data on the nasal airway in cleft-palate associated nasal dysplasia. A consecutive sample of 23 unilateral, 17 bilateral CLP patients and 15 controls with subjective normal nasal patency from a cleft-palate rehabilitation centre were studied. A series of transnasal acoustic measurements (pressure wave: 55 dB for 2 ms) of nasal volume were performed before and after topical decongestion with 2 x 0.3 mg of xylometazoline. A standardized regimen of acoustic parameters of the nasal valve and the adjacent segment of the nasal cavity were calculated. The cleft side yielded a sign…
The impact of isolated lesions on white-matter fiber tracts in multiple sclerosis patients
2015
Infratentorial lesions have been assigned an equivalent weighting to supratentorial plaques in the new McDonald criteria for diagnosing multiple sclerosis. Moreover, their presence has been shown to have prognostic value for disability. However, their spatial distribution and impact on network damage is not well understood. As a preliminary step in this study, we mapped the overall infratentorial lesion pattern in relapsing–remitting multiple sclerosis patients (N = 317) using MRI, finding the pons (lesion density, 14.25/cm3) and peduncles (13.38/cm3) to be predilection sites for infratentorial lesions. Based on these results, 118 fiber bundles from 15 healthy controls and a subgroup of 23 …
Pyomyositis of the iliacus muscle complicated with septic sacroiliitis
2008
We report a rare case of pyomyositis of the iliacus muscle in a 29-year-old woman. After 2 weeks of adequate treatment, secondary septic sacroiliitis occurred, a complication that had not been described previously. Pyomyositis of the iliacus muscle must be considered in the differential diagnosis of acute pain in the hip region.
