The work here exposed is divided in two studies: clinical and therapeutical. 1--Clinical. The occurrence of shoulder hand syndrome has been studied in 130 patients with hemiplegia. Although the preventive treatment was correct in all cases, 90 of them developed neurodystrophy. It is shown that the appearance and the intensity of this syndrome can be predicted with some certainly as soon as three weeks after the onset of hemiplegia, since there is a statistically significant correlation with the aetiology and the existence of some associated factors. 2--Therapeutical. The efficacy of eight treatments (
calcitonin
, blocking agents, intravenous clomipramine, blocking agents, periarterial injections of local anaesthetics, local or general corticotherapy, physiotherapy, kinesitherapy), randomly given to the patients, was compared (90 patients and 130 treatments). Local corticotherapy was the most efficient treatment. Physiotherapy was less efficient but always well tolerated. All the other treatments were much less active. Kinesitherapy was however always necessary to prevent joint
ankylosis
. No correlation was found between the intensity of the shoulder hand syndrome and the efficacy of treatments.

The innervation of the human intervertebral disc was investigated by immunochemical methods. Immunoreactivity to the general nerve marker protein gene product (PGP 9.5) was found in the outer annulus fibrosus of 11 of 12 discs removed during anterior
arthrodesis
for back pain. PGP 9.5-immunoreactive fibres ran between and across the collagenous lamellae, both in association with blood vessels and distant from them, and extended at least 3 mm into the disc. No innervation was observed in the nucleus pulposus. Fine fibres (< 1 micron in diameter) immunoreactive to
calcitonin
gene-related peptide and substance P (neuropeptides located in sensory and possibly nociceptive nerves) were identified in eight and four of the annuli fibrosi, respectively. Nerve fibres immunoreactive to vasoactive intestinal peptide and to the c-flanking peptide of neuropeptide Y were found in the majority of specimens of annulus fibrosus that were examined.

Studies have shown that the sensory nerves participate in inflammation and immune responses and possess trophic-facilitating wound healing in general. Tooth avulsion represents a pulpal and periodontal injury, and the mechanisms involved in the healing responses subsequent to replantation of teeth are still unclear. The objective of this study was to investigate the healing responses after denervation and replantation of teeth. Unilateral denervation was performed in 15 ferrets by axotomy of the inferior alveolar nerve, 5 days before extraction of the first lower premolars. Six weeks later the mandibles were excised and processed for histological evaluation. Immunohistochemistry was performed using antibodies against the sensory neuropeptides substance P (SP) and
calcitonin
gene-related peptide (CGRP), and measurements of root resorption and
ankylosis
were performed in four sections from each replanted tooth. After 6 weeks substantial reinnervation was observed in the jaws. Immunoreactivity in the pulp was observed in only two replanted teeth on the denervated side, compared with four on the innervated side. Total pulp necrosis appeared in 10 replanted teeth on the denervated side and in 5 on the innervated, indicating that sensory nerves promote survival of the pulp after replantation. SP-immunoreactive (IR) fibers were more frequently observed in the resorptive lacunae than CGRP-IR fibers. However, resorptive areas lacking IR fibers were frequently found along the root surface. Root resorption averaged 0.062 +/- 0.029 mm2 on the innervated side compared to 0.016 +/- 0.0043 mm2 on the denervated (P< 0.02).
Ankylosis
was observed in four of the replanted teeth on the innervated side (169.3 +/- 49.7 microm) and in six on the denervated side (332.56 +/- 193.2 microm) (P = 1). It is concluded that the sensory nerves promote root resorption after pulpoperiodontal injuries but have less influence on the osteoblastic activity expressed by
ankylosis
.

Aneurysmal bone cysts (ABCs) are among the most aggressive benign bone tumors, often occurring in both long bones and the spine. Treatment remains controversial as recurrence rates continue to be high. Treatment options include curettage with or without bone grafting, arterial embolization, en block resection with or without instrumentation or
arthrodesis
, radiation, and intralesional drug injections (steroids,
calcitonin
, doxycycline). We present the case of a patient with a thoracic vertebral ABC who underwent 2 rounds of doxycycline foam percutaneous injections. At the 1-year follow up appointment, all symptoms had been resolved. Repeat computed tomography and magnetic resonance imaging demonstrated that the ABC had nearly filled in completely with new bone. Our case demonstrates successful use of this percutaneous, less invasive method in the management of vertebral ABCs.
