Treatment of recurrent lingual nerve end-neuroma: A case report.

A neuroma is a collection of disorganized nerve sprouts emanating from an interruption of axonal continuity, forming within a collagen scar as the nerve attempts to regenerate. Lingual neuroma formation secondary to iatrogenic trauma to the tongue is likely not uncommon; however, we could not find a report in the literature of treatment of a distal tongue end-neuroma treated by resection and implantation into muscle. Here we describe a patient who experienced debilitating chronic tongue pain after excision of a benign mass. After failing conservative management, the patient was taken to the operating room where an end-neuroma of the lingual nerve was identified and successfully treated by excision and burying of the free proximal stump in the mylohyoid muscle. At 17 months postoperatively, she remains pain free without dysesthesias.

[Angiographic study of collateral circulation in coronary occlusion]. / Etude angiographique de la circulation de suppléance au cours des occlusions coronaires.

To define the collateral circulation pathways between coronary arteries, 101 coronarographies of patients who had at least one occlusion of a coronary artery (left-anterior descending artery, circumflex, right coronary) were analysed. We found 12 collateral pathways for the right coronary, 8 for the anterior descending artery, and 4 for the circumflex artery. These collateral circulation pathways have been mapped and compared to those of literature.

Magnetic resonance imaging of aneurysms and chronic dissections of the thoracic aorta.

Magnetic resonance imaging (MRI) was performed in 30 patients having an aneurysm or chronic dissection of the thoracic aorta. Using a magnetic field of 0.5 Tesla, multislice image acquisition was obtained by the ECG gated spin-echo imaging technique with dual-echoes. These results were retrospectively compared with those obtained in the same patients by angiography and computerized tomography (CT). In 10 cases of aneurysm, MRI measured their diameters and residual lumina and assessed the extension of the aneurysm with the same precision as CT scan and angiography. In 17 other cases, the diagnosis of chronic dissection was made by documenting an intimal flap and double channel filling of the aorta, and MRI compared favorably with CT scan. In three dissections in which the false lumen was thrombosed, MRI was unable to distinguish between dissection and partially thrombosed aneurysm. We believe MRI constitutes a useful noninvasive method for the study of aneurysms and chronic dissections of the thoracic aorta.

Echocardiographic ventricular shape analysis in congenital heart disease with right ventricular volume or pressure overload.

In this 2-dimensional (2-D) echocardiographic study, a computerized Fourier analysis technique refined from one that allows quantification of changes in septal shapes in normal fetuses, newborns and infants allowed analysis of left ventricular (LV) shapes in 14 patients with right ventricular (RV) volume overload (atrial septal defects), 5 with volume and pressure overload (total anomalous pulmonary venous connection), and 10 with pressure overload (complete transposition of the great arteries [TGA] with intact ventricular septum). Diastolic shape factors in the 3 groups were significantly different from those of normal subjects (p less than 0.01). Highest diastolic values were found in patients with TGA (mean 4.59 +/- 1.28). Systolic shape factors were similar in patients with atrial septal defect and normal subjects. Significant differences existed between normal subjects and patients with total anomalous pulmonary venous connection, with the greatest differences in systolic shape factor being 5.61 for TGA vs 1.87 (p less than 0.005) for normal subjects. Shape factor correlated well with hemodynamic data for RV/LV systolic pressure ratios (r = 0.93, p less than 0.001) for normalized interventricular pressure differences (r = -0.95, p less than 0.001). The lower the normalized systolic pressure difference or the higher the RV/LV ratio, the more the septum encroached into the LV cavity. Significant but weaker correlations were noted for values during diastole. Quantitative application of Fourier shape factor analysis to LV shapes allows numerical expression of visually interpreted distortions over a wide range of geometric alterations.

[Histological response of the endometrium to IUD's (author's transl)]. / Responses histologiques de l'endometre aux sterilets.

PIP: The authors performed 592 histological examinations of the endometrium in contact with 5 different types of IUD. 4 parameters were considered, the purely mechanical action of the device causing lesions on the endometrial surface, hormonal modifications, vascular modifications, usually related to menorrhagia and/or metrorrhagia, and inflammatory modifications, which can be related to IUD presence, or caused by external infection. The analysis of the histological parameters of IUD action of the endometrium showed their very complicated interrelation; the endometrium does nto simply react to a foreign body, the IUD, but it is a hormonal-dependent tissue, thus representing a link in a large and complex hormonal- and neurosympathatic system, which is, as yet, not perfectly known.^ieng
