[Thymus gland scan in myasthenia gravis: experience in 52 patients].

A firm relationship has been established between thymus gland pathology and myasthenia gravis. The most frequent changes observed in this gland consist in simple hyperplasia of germinal centers or thymoma. In order to detect these alterations it is necessary to have a suitable reliable technique, beside routine radiological exams: thymus scan has been proposed as an useful tool. Since 1968 we submitted 52 patients to this procedure; we used as a tracer 75Se-Seleniomethionine in most cases, 57Co-bleomycin and 67Ga-citrate in a few cases. The scan was found positive in 22 cases (42%) showing either localized or diffuse uptake in the region of the sternum. Thymus changes were subsequently examined in 26 cases: 22 cases after thymectomy in 4 cases at autopsy. We found a good correlation between positive scan and pathological changes of the gland such as thymoma or germinal center hyperplasia. However in 4 patients with negative scan that previously received radiation therapy or immunosuppressive therapy such pathology was missed: 3 cases of hyperplasia and 1 residual thymoma. We conclude that thymic scan an useful and highly specific diagnostic procedure and should be done before any kind of treatment which affects thymus.

[Aminoacid levels in Werding-Hoffmann and Kugelberg-Welander diseases (author's transl)].

The concentration of free aminoacids in plasma and urine were estimated in 10 patients suffering from Werdnig-Hoffmann's disease of long duration. The age of the patients was between 5 and 14 years. Estimations were also made in 10 patients with Kugelberg-Welander's disease aged between 11 and 34 years. The aminoacid concentrations were estimated on samples of plasma and 24 hours samples of urine by means of chromatography on ion-exchange resins. The data obtained were compared respectively with groups of thirty and ten healthy subjects of the same age. In the group of patients with Werdnig-Hoffmann's disease a significant increase of taurine (p less than 0.001) and of glutamic acid (p less than 0.001) was found in the plasma. The urinary excretion of glutamine was increased in the same group of patients (p less than 0.001) and in the group with Kugelberg-Welander's disease (p less than 0.005). These aminoacid levels are interpreted as an expression of a reduced oxygen metabolism and increased proteolysis in the skeletal muscles in conditions of chronic denervation.

[Hernioplasty using a Lichtenstein polypropylene mesh].

"Tension free" technique with prosthetic mesh for inguinal hernia repair was introduced since 1988 in Authors' Institution. In a review of 98 hernioplasties performed, only one relapse was observed (around 1%), while prosthetic infection cases were never observed. The disorder most frequently complained by the patients is a pain in the pubic area, persisting even months after the operation. Therefore this technique seems to be reliable, safe, and easy. While waiting for a long-term follow up to confirm these results, the Authors however suggest to limit the indications for this technique avoiding the use of prosthetic material in young patients since Shouldice's hernioplasty assures a low percentage of relapse for them.
