[Effects of local corticoids on the nerve fiber. Experimental study (author's transl)].

The intra-operative establishment of some impairments of the median nerve, in patients who are operated for carpal tunnel syndrome and who previously received several local injections of corticoids, led the authors to try to see the respective responsibility of the compression and of the injection in the degenerative process. In 60- dog cubital nerves, it has been possible, to study different parameters by intra and perineural (recurrent or not injections: the puncture, the dilatation, the solvents, the benzylic alcool and two long action corticoids very often used (triamcinolone acetonide, cortivazol). In the first of our series, the injections were done around the nerve and inside the nerve under visual or blind control (as for an infiltration). The nerves are then cut off after 1, 2, or 3 months. In the second of our series, the injections were done in the same way, but recurrently on the first, second and third month, and the nerve was cut off within the fourth month. An electrophysiological study was performed before taking the samples; they were then prepared for reading on the optical and electron microscope. The results show lesions characterized by an epineural spumous sediment, a localized decrease in the large fibers under the perineurium in the first and second series. These impairments seem to be diminishing with time. However when the injections are done recurrently, the lesions are more important, showing a wallerian degeneration and regeneration.

[Compressive pathology of ulnar nerve. Thirty seven cases reported (author's transl)].

The authors have reviewed 37 operated cases of ulnar nerve compression, on the level of the elbow and the wrist, with a minimum follow-up of one year. Traumatic etiologies are more common on these two levels. The authors find 32% of pure entrapment syndromes at the elbow, whereas this phenomenon does not seem to exist at the Guyon's loge. Mac Gowan's classification was used to range the patients in three degrees, according to the importance of the palsy before operation. Surgical treatment was is all cases, at least decompression. At the elbow was added anterior transposition of ulnar nerve beneath epitrochleal muscles or beneath the skin. Considering the results, these lesions are all the more severe, as they are higher (elbow) and more advanced.

Surgical importance of the radio-automatic study of the arterial vascularization of the forefoot.

The authors have studied anatomically and angiographically 50 cadaveric foot specimens, emphasizing; the vascular flow predominance between dorsalis pedis and plantar arteries; the anastomosis between the three arterial supplies in the foot; the dividing pattern and the distribution of each artery; the blood flow distribution pattern at the level of the first and second toes and especially the anastomosis between the dorsal and plantar vessels and the branches for the metatarsic-phalangeal joint. The study presents new data about the indications of preoperative angiography of the forefoot, about the surgical technique of toe transfer, articular transposition and multiple transposition (2 toes, skin and bone...).

Current aspects of tuberculous tenosynovitis. A report of six cases.

Tuberculosis of tendon sheaths of the hand was rare before the advent of antituberculous drugs. It seems now-a-days exceptional, for the published series become more an more uncommon and smaller. Therefore, the diagnosis is often an operative surprise on a patient with a painless, gradually developing tenosynovitis. No patient suffered from other active tuberculosis. But two of them had an old history of tuberculosis (knee and kidney). Analysis of other cases is inconclusive about the relation ship between trauma and tuberculosis. Histology and cultures establish the diagnosis. Surgical treatment consists in large excision of involved tissues. The damages provoked by the illness are often important, with sometimes tendon ruptures. However, functional results are surprisingly not so bad. Antituberculous drugs are the backbone of the surgical treatment for several months.

[Carpal tunnel syndrome].

The authors have reviewed 250 cases of carpal tunnel syndrome operated upon in a series of more than 400 cases. They also describe the results of an experimental study of the effects of locally injected corticosteroids on nervous fibers. Following a brief historical introduction, a detailed anatomical description is provided, with emphasis on congenital variations. The pathological, histological and clinical features of the disease are reviewed in the light of modern concepts of nerve compression. The cases in this series are classified according to their cause, among which idiopathic hypertrophic tenosynovitis was predominant. With regard to treatment, the authors conclude from their experience that repeated local injections of corticosteroids are dangerous, whereas surgical treatment is harmless and can be performed on out-patients under regional anaesthesia.

[Carpal tunnel syndrome: present views on causes and treatment. 250 cases (author's transl)].

The authors review a series of 250 patients with carpal tunnel syndrome who were operated upon and followed up, and report on an experimental study of the effects of local corticosteroid injections on the nervous fiber. Predominant among the various causes of syndrome were the so-called "rheumatic" conditions, chiefly fibrous hypertrophic tenosynovitis. Therapeutic indications and medical and surgical treatments are discussed. The need for limiting local corticosteroid therapy to one single injection is emphasized, together with the safety of surgical incision, which can be performed under nerve block anaesthesia and only requires a one-day stay in hospital.

[Bowen disease of the nail apparatus. Report of 5 cases and review of the 20 cases of the literature (author's transl)].

Five cases of Bowen disease of the nail apparatus were studied and the 20 cases published to date reviewed. The lesion was characterized by either periungual redness with scaling and erosions, whitish cuticle, hyperkeratotic or papilomatous process, fissure or crusted ulcer in the lateral nail fold or the nail bed with eventual partial or total destruction of the nail plate and sometimes soreness on the pressure. The key of the diagnosis is the histological picture, identical with that of Bowen diseases of other skin areas. Among the 25 cases, Bowen disease was found mainly in males (20 out of 25 patients) on the left fingers (17 out of 25 finger lesions) with particular involvement of the 1st, 2nd, 3rd finger nail. Hallux was concerned twice. The clinical picture can be protean and mimic verrucae, onychomycosis, paronychia, eczema, pyogenic granuloma, verrucous tuberculosis, subungual exostosis, glomus tumor, dermatitis vegetans, amelanotic malignant melanoma, kerato-acanthoma and of course squamous cell carcinoma. Treatment of choice is complete removal of the tumor by plastic surgery otherwise microscopically controlled excision following chemical fixation (Mohs) or fresh tissue technique.
