[The value of electromyographic studies in leprosy].

In Dakar, during a definite period of time, all the new leprosy cases have been subjected to an electromyographic examination before treatment: a total of 37 patients and 518 examined nerves including all clinical forms: NCV: 33% of the examined nerves are found to be affected. The sensory nerves are frequently and early involved. In frequency order: sural (54%), posterior tibial (50%), sensory ulnar (35%), sensory median (29%), motor ulnar (28%), lateral popliteal (17%) and motor median (12%). The study of the SCV seems relatively more reliable than the sensory testing in the case of the ulnar and the median (75 comparisons): concordance in 69% of the cases; SCV only abnormal in 19%; sensory testing only abnormal in 12%. The EMG detection is superior to the motor testing and to the motor nerve conduction for the lateral popliteal (32 comparisons): 41% of concordant examination; 59% of differences among which 44% of anomalies revealed only by detection.

[Correction of the Hansen claw hand using direct Zancolli lasso procedures and 2 of its variations].

The procedure of the Zancolli "Lasso" or V direct Zancolli uses a flexor superficialis tendon which after a distal section is turned inside out and is fixed on itself after forming a loop around the proximal pulley of the sheath of the flexor. The mode of distal fixation being the same, the authors also study two different methods which resort either to one tendon for two, three or four fingers, or only to one strip of the flexor tendon for one finger. 45 cases of this kind of operation are reported. In the most important series in which the principle procedure has been used, the results are good in 80% of the mobile claws and average in 70% of the stiffened claws. The cases operated according to the two different methods, less numerous, give approximately the same results. The suggested indications are in favour of the changes in the procedure.

[Prevention of perforating plantar ulcers: trial directed by a mobile team].

AIMS: to prevent the appearance of plantar ulcerations and then mutilations, by going in the field in order to: make suitable footwear, educate the patients, train the paramedical staff. Means: 1 fitted lorry, 1 physiotherapist, 1 shoemaker, and 1 educator. RESULTS: In one year, 206 patients have been provided with shoes and followed up. Advice have been taken exactly in the leper villages in which the attendance rate is of 98%; this rate varies between 47 to 70% in the all-purpose dispensaries. Paramedical workers of all-purpose Health Centers did not take great interest in this action. After 6-12 months under observation: 84% of good results for the feet without deformity or slightly deformed; 51% for the deformed feet. The results are quite satisfactory for the feet without plantar ulcer at the beginning, and that whatever the food deformity stage. But for the feet wounded by plantar ulcer at the beginning, 33% of recovery have been reported after wearing these shoes.

[Analysis of the results of treatment of Hansen's neuritis].

The authors expose a retrospective study about 133 nervous contingents treated exclusivement by steroid-therapy. The objective is to study the influence on nerve-function recovery of the following parameters: clinic form, function (sensitive or motor) of the nerve, position of the nerve (ulnar, median...), nature of the antibiotherapy. The method is based on the comparison for average progress in relation with the initial score. It appears that tuberculoid nerves recovery is better and faster than the lepromatous one. But lepromatous nerves improvement keeps on the end of the second year. On the other hand, the results are not influenced by the nerve itself or its function. Concerning antibiotherapy, our results show à significant difference, in consideration of a better improvement in PCT-treated nerves. Nevertheless, these results have to be confirmed by a comparative experimentation.

[Frequency of the association of perforating plantar leprotic lesions and truncal involvement of the posterior tibial nerve].

This study was performed to determine the electrophysiological status of the posterior tibial nerve and its muscular innervation in patients both with and without plantar ulcers without osteitis. In both cases, motor distal latencies remained normal, but the denervation of the plantar muscles was significantly more important in patients with ulcers. These results show that axonal degeneration is predominant in leprous neuritis affecting the tibial nerves. Neurolysis was performed in twelve patients in the retromalleolar part of the tibial nerve. All patients have recover from their ulcers, but no improvement of their electrophysiological parameters was observed.

[Treatment of leprotic neuritis. Exclusive medical treatment or combined with decompression].

The authors consider the evolution of the treatment of leprotic neuritis based on homogenous series of numerous observations (a minimum of 250-300). These observations are well registered and documented with some results dimensioned by the classical A. L. E. R. T. tests carried out at intervals of time and verified by comparison between series only medical treatment and series of medico-surgical treatment. Considering some remote results and some comparative series, the indications of the exclusive medical treatment have been well defined, and the ones of the surgical decompression have been reduced. The early case finding of a leprotic neuritis by the mean of easy methods as well as its monitoring during its early specific treatment is essential. By this way we get an important proportion of functional results: satisfactory (50 p.c.) or interesting (20 p.c.). In the case of painful hypertrophia, the complementary decompression secure not only the functional recovery of mortricity, but also the epicritic sensibility.
