Autotomy after nerve injury and its relation to spontaneous discharge originating in nerve-end neuromas.

Following transection and ligation of the sciatic and saphenous nerves, rodents frequently scratch and bite their anesthetic foot (autotomy). Many authors have suggested that autotomy is related to uncomfortable paresthesias induced by abnormal afferent discharge known to be generated in myelinated afferents in nerve-end neuromas. We report that preventing the development of ectopic neuroma discharge in rats by treating the severed nerves with colchicine or vinblastine does not prevent, or even detectably reduce, autotomy directed toward the denervated hindlimb. We conclude that abnormal discharge in myelinated afferents is not necessary for the expression of autotomy following nerve injury in rats.

Clinical experience with pimozide: emphasis on its use in postherpetic neuralgia.

Pimozide has been shown to be effective in the treatment of delusions of parasitosis and other monosymptomatic hypochondriacal conditions. In this paper it is shown that this benefit may be extended to severe cases of neurotic excoriations and to some cases of postherpetic neuralgia characterized by pain, paresthesias, and excoriations.

Disfiguring cutaneous manifestation of sarcoidosis treated with thalidomide: a case report.

A patient with sarcoidosis was treated with thalidomide for disfiguring and painful steroid unresponsive sarcoidal granulomas of the skin. The duration of the therapy was 14 months, during which time, the skin lesions resolved almost completely. The initial dosage was 200 mg a day, which was increased to 400 mg a day after 4 months. Episodic paresthesia of the finger tips and one lower extremity was the only side effect noted, which resolved promptly after discontinuation of the drug. The dramatic response of sarcoidal granulomas of the skin to thalidomide observed in this patient demonstrates the usefulness of this drug as a possible long-term monotherapeutic or steroid-sparing agent in the treatment of sarcoidosis.

Neurologic complications following immobilization of cervical spine fracture in a patient with ankylosing spondylitis.

Axial traction is widely recommended for stabilization of cervical spine fractures. This procedure may be inappropriate and even dangerous in patients with long-standing ankylosing spondylitis (AS). We present the case of an 80-year-old woman with AS who fell at home and suffered an unstable large C5-C6 fracture/dislocation associated with left-sided weakness and decreased sensation. Medical treatment included placing her neck in a neutral position, despite her preference for neck flexion. This procedure increased her pain and paresthesias; the complications decreased, but did not entirely resolve, when the patient resumed a semi-flexed position. This patient's neurologic sequelae may have been exacerbated by attempts to stabilize her neck in a neutral position. Standard stabilization recommendations should be appropriately altered in some patients with cervical spine AS.

Progressive ulnar palsy as a late complication of decompression sickness.

We report an unusual case of decompression sickness in which a progressive ulnar palsy developed 22 days after the onset of neurological decompression sickness. The initial symptoms of numbness and paresthesias of the hand were treated with recompression therapy, resulting in only partial relief. The patient subsequently developed weakness of the left hand, which increased in severity until the institution of repeated daily hyperbaric oxygen treatments. A total of seven treatments resulted in partial resolution of the patient's signs and symptoms. Recovery was complete within four months.

Nitrogen mustard therapy in children with frequent-relapsing nephrotic syndrome and steroid toxicity.

Nitrogen mustard (HN-2) is an alkylating agent known to be effective in inducing and prolonging remissions of nephrotic syndrome in children. The fact that the drug is administered intravenously eliminates the problem of compliance, and the fact that the treatment needs to be given only for a few days may lower the incidence of side-effects observed with other cytotoxic agents. We administered HN-2 to 12 children with the steroid-sensitive frequent-relapsing form of nephrotic syndrome, who had evidence of steroid toxicity. Life table analysis reveals a 46% sustained remission rate after 27 mo of follow-up. Complications of HN-2 treatment included only mild thrombophlebitis (2 patients) and mild local paresthesia (1 patient).

Intradialytic hypotension: is midodrine beneficial in symptomatic hemodialysis patients?

Symptomatic hypotension during hemodialysis is a disabling complication in end-stage renal disease (ESRD) patients, especially in certain groups of patients who are at higher risk for this problem. Autonomic dysfunction is thought to play a significant role. We evaluated the efficacy of midodrine, an oral agent with selective alpha-adrenergic agonist activity used in the treatment of neurogenic orthostatic hypotension, on 10 hemodialysis patients with persistent intradialytic hypotension. The patients were given a dose of midodrine (mean dose, 5.5 mg; range, 5 to 10 mg) 30 minutes before each hemodialysis session. We compared blood pressure, pulse, body weight, and laboratory values for 10 consecutive dialysis sessions off and on midodrine therapy. There was a statistically significant improvement in lowest intradialytic systolic blood pressure (from 96.6 to 114.7 mm Hg; P < 0.001), lowest intradialytic diastolic blood pressure (from 53.2 to 59.0 mm Hg; P = 0.002), lowest intradialytic mean arterial pressure (from 67.7 to 77.6 mm Hg; P < 0.001), posthemodialysis systolic blood pressure (from 116.5 to 127.1 mm Hg; P < 0.001), posthemodialysis diastolic blood pressure (from 66.6 to 69.7 mm Hg; P = 0.040), and posthemodialysis mean arterial pressure (from 83.2 to 88.8 mm Hg; P = 0.001) after patients were placed on midodrine. There also was a small but statistically significant decrease in intradialytic pulse rate (from 86.3 to 81 beats/min; P = 0.021) and posthemodialysis pulse rate (from 87.4 to 81.7 beats/min; P = 0.024) after initiation of midodrine therapy. There was no significant difference in any of the prehemodialysis blood pressure measurements or pulse rate off or on midodrine therapy. The improvements in intradialytic and posthemodialysis blood pressure were associated with a uniform subjective improvement in symptoms associated with dialysis hypotension, such as cramps, fatigue, dizziness, and weakness. Other than scalp paresthesia in one patient, no adverse effects were noted. Our results suggest that the administration of a single dose of midodrine before hemodialysis is an effective therapy for intradialytic hypotension. A prospective trial with adequate patient numbers and long-term follow-up would be useful to evaluate this drug's efficacy and safety profile in patients with ESRD.

Aneurysmal bone cysts of the maxilla: a clinicopathologic review.

PURPOSE: This study evaluated the significant differences in clinicopathologic features of aneurysmal bone cyst in the maxilla and mandible. MATERIALS AND METHODS: A search of the literature showed 30 recorded maxillary cases, and these together with one previously unrecorded case formed the basis of the study. RESULTS: There were no differences in the age and sex incidence. Only two patients complained of pain, and no patient complained of tenderness. No patient gave a history of trauma. Swelling was present in virtually every patient. In seven cases, there was tooth mobility or migration of teeth. Two patients complained of paresthesia. Four patients presented with proptosis, two of whom complained of diplopia. The radiographic appearance of the aneurysmal bone cyst is suggestive but not diagnostic. CONCLUSION: Although these differences do not enable the clinician to make a definitive diagnosis before biopsy, they have important implications for management.

Long-term effect of mandibular midline distraction osteogenesis on the status of the temporomandibular joint, teeth, periodontal structures, and neurosensory function.

PURPOSE: This study retrospectively evaluated the long-term effects of transverse symphyseal distraction osteogenesis (DO) on the temporomandibular joint (TMJ) symptoms, periodontal health, tooth vitality, and nerve injury after surgery. PATIENTS AND METHODS: Twenty-three patients were treated with symphyseal DO during a 4-year period. Fifteen patients were available for follow-up from 7 to 45 months postoperatively (ave, 24.5 months). The patients were clinically evaluated for TMJ symptoms, periodontal pocket formation, tooth vitality and mobility, crestal bone loss, and attached gingival tissue changes. Radiographs of the mandibular anterior teeth were used to evaluate for periodontal bone loss, periapical lesions, or widening of the periodontal ligament (PDL). RESULTS: Preoperatively, 47% of the patients had TMJ symptoms. No patient had symptom worsening or developed new symptoms postoperatively. Five patients' TMJ symptoms improved, and 3 experienced complete resolution of symptoms. No periodontal bone loss or soft tissue recession were evident. Tooth vitality was maintained in 13 patients. Two patients developed Class II mobility of 1 mandibular central incisor, 1 patient had tooth pain and a widened PDL adjacent to the osteotomy/corticotomy site, and 1 patient experienced mental nerve paresthesia. CONCLUSIONS: DO can be used to treat transverse discrepancies of the mandible with limited morbidity.

Metastatic head and neck squamous cell carcinoma to the brain.

BACKGROUND: To evaluate the natural history of patients with metastatic squamous cell carcinoma (SCCA) of the head and neck to the brain. METHODS: A retrospective review of patients with brain metastases treated over a 20-year period identified five that had a head and neck SCCA primary. RESULTS: Five cases of patients with SCCA of the head and neck that developed brain metastases are presented in detail. CONCLUSION: In patients with aggressive disease, large infiltrative lesions, and in late survivors with initially advanced disease, metastasis to the brain should be considered. Perineural metastasis appears to be the most common mode of spread of head and neck SCCA to the brain. Pain, paresis, or paresthesias in the distribution of cranial nerves or other neurological symptoms should alert the otolaryngologist to neural or central nervous system involvement in patients with SCCA of the head and neck. Surgery with or without post-operative whole brain radiation therapy is the mainstay of treatment in most patients. Stereotactic radiosurgery may play a major role in treating brain metastases from head and neck primary tumors.

[The role of posterior bracket plate osteosynthesis in the treatment of compression-extension fractures of the distal end of the radius].

Osteosynthesis without immobilisation of compression-extension fractures by means of a posterior plate was studied in prospective series with a minimum follow-up of six months (first group: 73 patients) and a minimum follow-up of one year (second group: 63 patients). The clinical results were evaluated and showed several complications (no infection, but reflex sympathetic dystrophy, paresthesia, unsightly scars). The clinical and radiological findings (radio-ulnar index) could improve with several technical devices, now used.

The carpal tunnel syndrome in chronic dialysis patients, it is a late complication of the arterio-venous fistula?

Out of 100 patients undergoing chronic hemodialysis in Lausanne (Switzerland), 12 developed a carpal tunnel syndrome (i.e. 8 men and 4 women, from 34 to 76 years old). Out of 66 patients with an arteriovenous fistula for less than 4 years, it is interesting to note that only 3 carpal tunnel syndrome were observed; whereas, out of 34 hemodialysis patients being dialyzed more than 4 years, 9 of them showed that syndrome. The symptomatology of the carpal tunnel syndrome is described by the authors. It has always been confirmed by EMG. On 10 patients, the symptoms were so acute that they needed a decompression of the median nerve. Five cases were bilateral. The operation is performed under axillary block, without tourniquet. The results were very satisfactory. Paresthesias disappeared after a few hours or a few days following the operation. No relationship could be established between CTS and the type of nephropathy, severity of polyneuropathy, Ca and P metabolism, vascular access complications, efficacity of dialysis, fluid overload or medical treatment. The authors are investigating the etiology of the carpal tunnel syndrome, ship hypothesize particularly concerning the direct or remote relation between the carpal tunnel syndrome and the arteriovenous fistula.

[Retrosternal luxation of the clavicle. Apropos of 4 cases surgically treated using a temporary screwed anterior plate and review of the literature].

The authors report 4 new cases of retrosternal dislocation of the clavicle operated by capsular and ligament restoration, and temporary stabilization by anterior plating. The 4 patients were men with a mean age of 17.5 years. The lesion was caused by a sports injury (football, rugby) in 3 out of 4 cases and was related to an indirect mechanism. Clinical examination allowed the diagnosis, was related to based on painful palpation of a dip over the joint, supported by radiology and computed tomography. CT did not reveal the epiphyseal separation present in two cases. Complications were frequent: 1 case of tracheal compression, 2 cases of temporary paresthesia of the upper limb, 2 cases of venous compression with one case of subclavian and medial jugularis venous thrombosis, 1 hemopneumothorax. Surgical reduction was performed in all 4 cases after 2 failures of attempted orthopedic treatment under general anesthesia. All patients recovered a full range of movement, a painless shoulder and no recurrence has been observed. All complications resolved after reduction. Venous thrombosis responded favourably after 6 months of anticoagulant therapy. One plate breakage was observed with no clinical implications. On the basis of an extensive review of the literature, the authors discuss the epidemiology, pathology and the importance of associated injuries, which are frequent and sometimes serious, justifying urgent reduction. Computed tomography is the most useful radiologic modality, both for diagnosis and for investigation of complications. Orthopedic treatment must be attempted first (especially in children) according to a well systematized technique. One third of attempts fail, and cases of delayed diagnosis and serious vascular complications, then require surgical treatment. The costoclavicular ligament is repaired either by Burrows's ligamentoplasty or by bone suture; the clavicle is stabilized by bone suture or by anterior plating. The authors do not advocate either joint fixation by Kirschner wire, or resection of the medial end of the clavicle.

Neck-tongue syndrome.

Two patients with neck-tongue syndrome, a rare disorder of the upper cervical nerves that results in paroxysmal neck pain and paresthesia of the tongue, are described. Signs are the result of compression of the C2 root by disorders affecting the first two cervical vertebrae. Conservative management is effective in most cases if no masses are in the involved area. The disorder has been observed rarely in children. Clinical onset occurred at 6 and 11 years of age, respectively, in the reported patients.

At which stage of sensory recovery can a tingling sign be expected? a review and proposal for standardization and grading.

The phenomenon of paresthesia elicited by percussion of regenerating axons is usually associated with Tinel and Hoffmann, who both described it separately in 1915, although the same phenomenon had been described previously, in 1909, by Trotter and Davies. This sign is used widely, but its standardization is almost completely lacking, its grading is seldom used, and its reliability or validity is scarcely mentioned in the literature. The authors present a method of standardization and grading of the tingling response by means of a vibrostimulator, which permits precise localization of the trigger point and uniform stimulation. The tingling response may then be classified according to its location and to the magnitude threshold at which the response is triggered. In the distal part of the nerve, after neurotmesis repair, the tingling sign is graded T++ (tingling after a weak stimulus) and T+ (tingling only after a strong stimulus). At the site of the injury, the initial tingling sign is graded T0. The sign is graded T00 if, independent of recovery, a slight positivity persists at the initial site of injury. Grading of sensory recovery is poorly standardized, since different authors use different variations and modifications of existing classifications. The authors of this paper present a cross-matching of these classifications and propose to use Dellon's modification of Zachary's classification in eight stages, from S0 to S4. A discussion of the probability of eliciting a tingling sign during axonal regeneration concludes that the clinician can expect to trigger a T+ + sign when sensory recovery evolves from stage S0 to stage S1 and should no longer expect to trigger one when sensory recovery improves from stage S2+ to stage S3.

An analysis of the safety of performing dobutamine stress echocardiography in an ambulatory setting.

Dobutamine echocardiography has become widely used in the past decade in the evaluation of patients with suspected coronary artery disease who are unable to undergo exercise treadmill or bicycle testing. The safety of this procedure has been studied in a hospital-based setting. However, no studies thus far have evaluated the safety of this procedure in an office-based setting, remote from a hospital. We performed dobutamine echocardiography on 127 patients in an office-based setting, remote from a hospital. Throughout the course of this study there were no deaths, myocardial infarctions, sustained episodes of ventricular tachycardia, or syncopal episodes associated with dobutamine infusion. The frequency of noncardiac side effects was 29%, the majority of which were nausea, vomiting, and paresthesias. Three patients had nonsustained ventricular tachycardia, none of whom had symptoms. We conclude that dobutamine echocardiography is safe, well tolerated, and useful in an office-based setting.

Arteriovenous malformation of the mandible: report of a case with a note on the differential diagnosis.

Arteriovenous malformations are extremely rare conditions that can result from congenital or acquired abnormalities in the structure of blood vessels; they are potentially fatal. Arteriovenous malformations may be asymptomatic or may show various signs and symptoms including soft tissue swelling, pain, changes in skin and mucosal color, erythematous and bleeding gingiva, bruit, and paresthesia. Radiographically, there are no pathognomonic features. The present case illustrates an arteriovenous malformation in a 16-year-old Hispanic female. The case report is unique because the malformation was previously interpreted as a pathosis of pulpal origin and was initially treated as such, although the tooth showed no gross or radiographic dental caries. A broad view of the diagnostic imaging, radiographic differential diagnosis, treatment, and histopathologic description is also presented.
