Treatment of dystonia in extensor hallucis longus and digitorum muscles with neurotomy of the branches of the deep fibular nerve: Preliminary results.

INTRODUCTION: Dystonia in extensor hallucis and/or digitorum muscles can be observed in pyramidal and extrapyramidal lesions and results in pain in these toes, spontaneous or when walking, problems and discomfort when putting on shoes and socks, and cutaneous lesions on the toes. The objective of this study was to assess the efficacy and safety of deep fibular nerve neurotomy for the extensor hallucis longus (EHL) and/or the extensor digitorum longus (EDL) branches in the treatment of extension dystonia of the hallux and/or other toes. PATIENTS AND METHODS: A deep fibular nerve neurotomy was performed in 20 patients (n=19 for the EHL, n=6 for the EDL). We retrospectively analyzed the treatment's efficacy and safety and assessed the patients' self-reported improvement and overall treatment satisfaction. RESULTS: Dystonia totally disappeared in 15 cases (75%); it persisted at a minimal level in the other patients. The patients reported a decrease in pain (P<0.01) and fewer difficulties putting on shoes and socks (P<0.001) and had a high median level of satisfaction (8.5/10). Adverse effects were rare and transient. The identification of the nerve branches was sometimes difficult. DISCUSSION: Deep fibular nerve neurotomy for the EHL and/or EDL branches seems to be an effective treatment for extension dystonia of the hallux and/or other toes and its consequences for the adult neurological patient. However, these encouraging preliminary results should be confirmed by prospective, longer-term studies.

Double tendon transfer for correction of drop-foot.

Many conditions can cause foot drop, which makes walking difficult because the foot easily bumps into obstacles, or the knee must be kept more flexed than usual during the swing phase of gait, especially when going up stairs. Several techniques that have been described to correct foot drop rely on bone procedures or tendon transfer, with or without bone fixation. In this article, we describe a simple technique that is heavily used in leprosy-endemic countries and provides long-lasting results. It requires a double tendon transfer through the interosseous membrane of leg; the tibialis posterior and flexor digitorum longus are sutured to the tibialis anterior, and extensor hallucis longus and extensor digitorum longus, respectively, proximally to the extensor retinaculum.

An unusual cause of foot clonus: spasticity of fibularis longus muscle.

The functional consequences of spasticity can be corrected by local, pharmacological or surgical treatments once the spastic muscle has been identified. However, this diagnosis can be tricky when the muscle in question is rarely involved in spasticity or when its mechanical action is unusual or poorly characterized. Here, we present the case of a man presenting with left hemiplegia after an ischaemic stroke. His gait was perturbed by foot clonus in the sagittal plan, which persisted after selective neurotomy of the gastrocnemius and soleus but disappeared after neurotomy of the peroneus longus. Clonus triggered by pushing up under the whole of the forefoot in the direction of dorsiflexion may not be related to spasticity of the triceps surae. We recommend screening for foot clonus by first pushing up on the sole of the foot under all five metatarsals. In a second step, selectively pushing up under the first metatarsal joint enables the physician to evidence spasticity of the peroneus longus.

[How does one treat the osteitis and osteoarthritis of the extremities in older leprosy patients using granulated table sugar?]. / Comment guérir les ostéites et ostéo-arthrites des extrémités des anciens malades de la lèpre par le sucre cristallisé alimentaire?

A common problem of osteitis and septic arthritis is the recurrent bone infection after surgical debridement, a problem frequently encountered in patients with sequela leprosy. In these cases the authors propose the use of an ancient method of post surgical wound care based on the treatment with ordinary granulated sugar. The hyperosmolar climate created this way in the wounds inhibits the bacterial growth, enhances bacterial death and therefore permits the growth of granulation tissue in order to recover the debrided nude bones. At ILAD (Leprosy Institute of Dakar), 36 osteitis and septic arthritis were treated and healed during the last 2 years from March 1995 to March 1997 using this technic. All the wounds healed in the mean-time of 44 days. Only two of them needed a second debridement and healed afterwards. Up to now the method using ordinary sugar was applied in the treatment of infected wounds, eschars and postsurgical infections. Our experience shows that it also can be indicated to treat bone infections. This method is easy to apply also under often difficult field conditions and is very cheap.

[Can plantar ulcers associated with leprosy be treated in the field. Results of experience in Senegal]. / Peut-on soigner les maux perforants plantaires des anciens malades de la lèpre sur le terrain? Résultats d'une expérience au Sénégal.

The introduction of a program for the treatment of plantar ulcers (PU) in field conditions in Senegal was studied. The program was complementary to the Health Education and Protective Footwear to Prevent Disability (POD) initiatives within the Senegalese anti-leprosy program. The wound care given in health centers was coded and simplified. Access to hospitals was made easier for those patients requiring surgery. More than 30% of patients with PU were treated each year, with a mean of 62% cured. An increasing number of leprosy patients have been admitted to regional hospitals for surgery. Never before have patients with signs of leprosy had access to general hospitals. This study emphasizes the need for regular supervision of the individuals treating wounds.

[Should biopsy be done on the sensory branch of the radial nerve in leprosy patients? Apropos of 112 cases]. / Doit-on pratiquer des biopsies de la branche sensitive du nerf radial chez les malades lépreux? A propos de 112 cas.

Biopsies of the superficial sensory branch of the radial nerve are contested. Some authors mention it to be simple and without harm, but others are formally against this procedure. At ILAD, 274 biopsies were made between 1986 to 1992. We present a review of 112 leprosy patients for whom biopsy was done. On 112 reexamined patients, we observed 2 benign neuroma, hence 2%. The comparison of nerve function before biopsy and after, of 63 of the 112 patients, reexamination shows no significant modification of the functional score. Given even the occurrence of benign neuroma in only 2% of the cases, the authors do not recommend the biopsy of the superficial sensory branch of the radial nerve. For research purposes on neuritis in leprosy, as well as to assure diagnosis in primary neuritic leprosy, we propose the biopsy of the sensory branch of the musculo cutaneous nerve at elbow level.

[Simplification and codification of treatment for leprous plantar ulcers]. / Simplification et codification des soins aux maux perforants plantaires lépreux.

Practically leprous plantar ulcers (PU) are difficult to treat and heal under field condition. Considering the important number of patients showing a PU, the directors of national leprosy control programmes are determined, within the programmes on prevention of disabilities (POD), to treat the PU in the field. Therefore it appears to be essential to codify and simplify their treatment thus enabling it to be effective. The healing of PU being the only criteria of effectiveness of the technique. Four clinical stages were defined, each corresponding to a precise way of treatment using only essential and basic products at low cost. During the trainings about the treatment techniques and attitudes much emphasize is given on the discharge of the PU, on the trimming of the wound and on the products to use according to PU's evolutionary stage.

Pseudoepitheliomatous hyperplasia in trophic ulcers in leprosy patients. A 28-case study.

Between 1984 and 1993, pseudoepitheliomatous hyperplasia developing in chronic ulcers were observed in 28 former Senegalese leprosy patients, which amounts to an annual frequency of 1.9 per 1000 ulcers. Correct diagnosis could only be made by histopathological examination of specimens taken from the depth of the lesion. Amputation was carried out on 17 patients and local excision on the other 10. Recurrence of growth was observed in 8 of the 10 patients treated by excision; in all of these 8 cases below knee amputation had to be subsequently performed. From our experience, it may be assumed that local excision should be carried out only in the case of small tumours. Since the aim of surgical procedure is to allow the patient to have physical autonomy, below knee amputation, followed by adaptation of prosthesis, should be the procedure chosen in the other cases.

[External canthopexy using the Edgerton-Montandon procedure in lagophthalmos of leprosy patients. Technique and indications. Apropos of 30 cases]. / La canthopexie externe selon le procédé d'Edgerton-Montandon dans les lagophtalmies des malades de la lèpre. Technique et indications. A propos de trente cas.

This paper deals with the results observed in 21 ancient leprosy patients suffering from lagophthalmos (13 of whom suffered from bilateral lagophthalmos) and treated by the Edgerton-Montandon surgical procedure which associates lateral canthopexy and tarsorraphy. Eighteen of the 21 treated patients were reviewed at one month after the procedure and, overall, results could be evaluated for 30 eyes. Improvement was noted in all of the 30 eyes and, globally, the residual palpebral fissure (during voluntary closing of the eyes by the patient) decreased from 6.7 mm before the procedure to 1.8 after the procedure. The following recommendations may be proposed. For young patients with intact corneal sensation, the Gillies procedure remains the procedure of choice to correct lagophthalmos. For older patients with corneal anesthesia, at high risk of blindness, the Edgerton-Montandon procedure should be recommended.

[Organization of a program for the prevention of disabilities and physical rehabilitation at the center of a national program in the campaign against leprosy: practical advice]. / Organisation d'un programme de prévention des invalidités et de réadaptation physique (PIRP) au sein d'un programme national de lutte contre la lèpre (PNL): conseils pratiques.

Patients treated and cured on the bacteriological level by multidrug therapy may nevertheless present handicaps, such as deformities resulting from the disease, which have personal and social consequences. It is actually the handicap and disability from which most patients suffer and which concern populations. The number of persons suffering from such handicaps worldwide has been estimated at 4 million. Therefore, the main goal is to gradually integrate the activities of the prevention of disabilities and physical rehabilitation programme (PIRP) into the national leprosy control programme (PNL). The persons involved in the implementation of the programme outline the activities planned under the PIRP, detailed objectives, priorities, the means by which they will be implemented, the content of training programmes, assessment criteria and documents available.

[Tumoral proliferations in chronic plantar ulcers: how to treat?]. / Proliférations tumorales développées sur maux perforants plantaires: quelle attitude thérapeutique?

Between 1983 and 1994, 66 Senegalese leprosy patients were seen for cauliflower growths developed in chronic plantar ulcer (CPU), (2 patients had each 2 tumors). 68 biopsies for pathological examination were taken: the diagnosis of squamous cell carcinoma was effectively made in 39 cases (38 patients) and that of pseudo-epitheliomatous hyperplasia in the remaining 29 cases (28 patients). The mean annual frequency of cauliflower growths was 0.45 per 100 CPU. Among these tumors, the percentage of carcinoma was 57%. Of the 38 patients with a carcinoma, 5 refused amputation and all of them died. The 33 others were amputated and of these 8 died as a direct result of their carcinoma (24%). In the case of the 28 patients with hyperplasia, amputation was carried out on 18 patients and local excision on 10. In the months following the operation 8 recurrences were observed in 10 of the patients on whom excision had been carried out. These recurrences were treated by amputation. This gives a total of 93% of amputations in the cases of hyperplasia. These facts lead as to conclude that at least in countries where pathological examination is not available below knee amputation is the most reasonable action to take in the proliferative tumors developed on a CPU.

[Results obtained by a mobile handicap-prevention unit at the Institut de Léprologie de Dakar]. / Résultats obtenus par une équipe mobile de prévention des invalidités à l'Institut de Léprologie de Dakar.

Of 584 leprosy patients known at the Institut de Léprologie Appliquée de Dakar because they suffered a nerve lesion with or without chronic plantar ulcer (CPU), 242 (41%) could be followed-up during a mean period of time of 8.2 years (range: 5 and 10 years) by the means of the mobile disability prevention team (health education, medical care and shoe workshop). Every two months a visit of the patients, at their home town, was organized, with the purpose to assess whether they could actually put into practice the foot and hand as having been trained for. At the same time, further advice and encouragement were given to the patients. Adapted footwear was brought to the patient, at reduced fee, the foot prints and special moulds having been taken during the previous visit. The local health worker were responsible for light surgical cares. Among the 242 followed-up patients: of 107 without CPU at beginning, 90 (84%) remained so, of 135 with CPU at beginning, 57 (42%) were cured, of 135 with CPU at beginning, 74 (55%) remained stable (no worsening), the last 21, of whom 17 showed severe foot deformities but without CPU, worsened (all presented one or more CPU at the last control). Of the 242 patients, 221 (91%) remained stable or showed substantial improvement. Therefore, it must be emphasized that careful follow-up of patients is essential to insure the improvement or care of CPU as well as to prevent the onset, worsening or reappearance of CPU. Such follow-up must consist of cares, health education and special shoe wearing.

[The frequency of the appearance of perforating foot ulcers in patients with Hansen's disease as a function of treatment with disulone alone or with polychemotherapy]. / Fréquence d'apparition de maux perforants plantaires chez des malades hanséniens en fonction du traitement par disulone seule ou polychimiothérapie.

Between 1986 and 1989, in 5 departments of Senegal, 436 new cases of leprosy were detected, of whom 225 were put under dapsone monotherapy and 211 under multidrug therapy (MDT). Of them, 190 could be followed-up during 2 years by means of annual bacteriological and clinical examination, including neurological assessment. In 2 years, the onset of 10 (5.3%) chronic plantar ulcers (CPU) was observed: 4 (4%) among the 99 patients under dapsone monotherapy and 6 (6.6%) among the 91 under MDT (no significant difference). Of the 10 CPU, 3 (2%) appeared among the 149 patients without any disability at detection while 7 (17%) were observed among the 41 others who presented a grade 1 disability at detection (p < 0.01). Of the 6 CPU appeared in the patients under MDT, 5 (22%) were observed among the 23 who presented a grade 1 disability at detection and 1 (1.5%) among the 68 who did not (p < 0.01). This difference was not noted in the patients under dapsone monotherapy. Our results need to be confirmed by other studies including a higher number of patients followed-up during a longer period of time. Nevertheless, they suggest that MDT could prevent the onset of CPU, but only in patients without any disability at detection. Therefore, they reemphasize the importance of early detection of the disease in leprosy control programmes.

[Characterization of chronic plantar ulcers in former leprosy patients]. / Cancérisation des plaies chroniques plantaires chez les anciens malades de la lèpre.

Between 1988 and 1992, 21 biopsies for pathological examination were taken from 20 Senegalese leprosy patients suffering from chronic plantar ulcers (CPU) suspected of malignant transformation. The diagnosis of squamous cell carcinoma was effectively made in 13 cases and that of pseudoepitheliomatous hyperplasia in the remaining 8 cases. The mean period of time between the onset of CPU and that of malignant transformation was 10 years (range: 1 to 15 years); the mean annual frequency of the malignant transformation was 2 per 1,000 CPU. In countries where pathological examination is not available, below knee amputation could be considered whenever main clinical signs of malignant transformation are present. In countries where pathological examination is available, the therapeutic decision may differ according to the diagnosis: below knee amputation supplemented with block dissection of inguinal lymph nodes whenever possible in cases of carcinoma; below knee amputation depending on the function status of the foot and on the volume of tumor in case of pseudo-epitheliomatous hyperplasia.
