[A rare renal tumor: cavernous hemangioma. Apropos of a case].

The authors report a case of cavernous hemangioma of the kidney, a rare benign tumor. The interest of this case is probably to be the only one reported with MRI: an high signal intensity T2 in weight sequence could represent in the future a good information for the diagnosis. Endoscopic methods are useful for the diagnosis, but cannot be used for therapy.

[Anterior instability of the shoulder associated with fracture of the coracoid process. Apropos of 3 cases].

Purpose Of The Study: The aim of this paper is to present an unusual lesion associating anterior instability of the shoulder with a fracture of the horizontal part of the coracoid process. It emphasizes surgical treatment using the Latarjet procedure.

Material And Methods: Three cases are presented: One case was a recurrent anterior dislocation of the shoulder associated with a fracture of the horizontal part of the coracoid process; an other case was a painful shoulder associated with pseudarthrosis of the coracoid process and a fracture of the anterior and inferior edge of the glenoid.

[A new titanium-carbon finger joint implant. Apropos of 15 initial cases].

Arthroplasty of the MP and PIP joint remains a therapeutic challenge for the hand surgeon. The poor results of the currently available implants are due to their mechanical conception (non strained) or their material (silicone causing instability, ruptures and silicone synovitis). The authors present the preliminary results of a new digital articular implant (IAD).

[Restoration of opposition using the extensor pollicis longus. Apropos of 8 cases reviewed after 11 years].

Moutet and coll. had studied in 1986 a series of 16 cases of restoration of thumb opposition by extensor pollicis longus transfer onto abductor pollicis brevis through the inter osseous membrane. Eleven years follow-up revision of 8 of those 16 patients was performed by the authors.

[Use of an implanted electrode for rehabilitation after tenolysis of the flexor tendons].

The electric stimulation is widely used in flexor tenolysis rehabilitation by the authors. Since 1983 implantable electrodes were used during the operative procedure. Actually they gave better access to the deep muscles (Flexor Profundus of the index), better specificity, less dysesthesia of the skin.

[A proposal for a functional evaluation record for the hand].

Proposition of a new evaluation method included an analytic cotation, a functional cotation, and a cosmetic cotation. Use is speeded by the suppression of all kind of measure instrument and facilited by pictures. Application to the corporal damage evaluation.

Insulin secretion, clearance, and action on glucose metabolism in cirrhotic patients.

To study the mechanisms of glucose intolerance and hyperinsulinism in liver cirrhosis, we compared the plasma glucose, insulin, and C-peptide levels during a frequently sampled i.v. glucose tolerance test (0.

Right-sided pneumothorax as a result of a left-sided chest tube.

Chest tubes are inserted for a variety of reasons, and a number of complications have been associated with their use. We report a case of traumatic hemopneumothorax in which the chest tube crossed the mediastinum into the contralateral lung causing a pneumothorax. Its position was not apparent on portable chest radiographs.

Histoplasmosis of the penis.

Histoplasmosis is a common cause of systemic mycosis in endemic areas of the United States. Genitourinary and cutaneous involvement with this dimorphous fungus is rare. We report a case of disseminated histoplasmosis associated with nonpainful ulcerative lesions of the glans and shaft of the penis.

Platelet serotonin is a mediator potentially involved in anaphylactic reaction to neuromuscular blocking drugs.

A platelet serotonin release test was performed on blood from 10 patients who had suffered from an IgE-dependent allergic reaction to a neuromuscular blocking drug. The results were compared with those of a leukocyte histamine release test. The upper limit of serotonin release induced by neuromuscular blockers was estimated to be 2.

Isolation of the physiological regulation component of the arterial pressure time variation after postural stresses in by a model of the gravitational and arterial kinking effects.

Prompt active postural manoeuvres induce an immediate arterial pressure variation followed by a period of regulation. For the squatting manoeuvre, initial hypertension was explained by a rise of cardiac filling pressure due to "squeezing blood out of the veins of the legs", leading to an increase in stroke output by Frank-Starling mechanism. For a minor part, it was also explained by "kinking" of the femoral arteries.

Imaging implications in the evaluation of permanent needle acupuncture.

Traditional Chinese acupuncture involves placing needles into the subcutaneous tissues along predefined meridians, and later totally removing the needles. A peculiar form of acupuncture exists called "Hari", which involves the permanent placement of fine needles into the subcutaneous tissues. Although this form of acupuncture is uncommon, it is still practiced in both the Orient and the West.

[Synthetic ligament reconstruction of the thumb metacarpophalangeal joint. 21 cases].

Since 1984, the authors have performed ligamentoplasties of the metacarpophalangeal (MP) joint of the thumb with Dacron mesh. A series of 21 cases is reviewed and tested clinically with a mean follow-up of 34 months. The MP joint remained stable.

[Subcutaneous rupture of long finger flexor pulleys in rock climbers. 12 case reports].

Rock climbing generates a new type of microtraumatic, stress pathology involving all of the osteoarticular chain of the upper limb. The hand is the site of specific lesions: pulley ruptures (A2) are the most frequent. 12 top-level climbers (7a and above) were reviewed out of a series of 23 cases.

[Protected early mobilization using Levame's device after primary repair of the extensor tendons of the hand. Apropos of a series of 88 cases].

Seventy patients with 88 lesions of the hand extensor apparatus were treated by primary repair followed by post-operative mobilisation with a dynamic steel blade splint (Levame). Results were good or very good in 97.7% of cases and moderate in 2.
