A surgical approach to the cervicothoracic spine.

We describe a method for approaching the lower cervical and upper thoracic spine, the brachial plexus and related vessels. The method involves the elevation of the medial corner of the manubrium, the sternoclavicular joint, and the medial half of the clavicle on a pedicle of the sternomastoid muscle. We have used this exposure in 17 cases with few complications and good results. Its successful performance requires high standards of anaesthesia, surgical technique and postoperative care.

Clinical studies of a vegetarian food diet mixture.

A vegetarian food mixture when incorporated into a commercially prepared diet can be used as a supplement or in a vegetarian protein-sparing modified fast. A modification of this diet was given to protein-energy deficient malnourished children in Ethiopia, and it reversed their biochemical defects. The soluble or gel-forming fiber in the mixture also gives the product a favorable glycemic index and reduces glycemic excursion as well as fasting blood glucose and insulin levels. This accounts for the improvements seen in glucose tolerance in type II diabetic patients. These results, however, were preceded by a study of the effects of the mixture in improving glucose tolerance in diabetic rats. A clinical study among New Orleans police officers also suggests that this mixture helps people, without much self-motivation, to lose weight.

Operations to restore elbow flexion after brachial plexus injuries.

We have reviewed 50 patients at a mean period of 2.7 years after operations to restore elbow flexion lost as a result of traction injuries of the brachial plexus. A variety of operations were used and, in general, patient satisfaction was high. Objectively, however, the power in the transferred muscles was poor; less than half of the patients had a significant improvement in function. Poor control of the shoulder often compromised the result. Latissimus dorsi and triceps transfers proved most reliable, and some Steindler flexorplasties also gave satisfactory results. Pectoralis major transfers were disappointing and we do not recommend their use in women.

Experience with the free vascularized ulnar nerve graft in repair of supraclavicular lesions of the brachial plexus.

The treatment consisted of a free vascularized ulnar nerve graft in 63 patients with lesions of the supraclavicular brachial plexus. Since 1978, the outcome in 42 patients with a minimum follow-up period of 30 months was certainly better than with an avascular segment of ulnar nerve. Clear proof of hopeless prognosis for recovery along the course of the ulnar nerve is essential before using this graft. The early operations used the ulnar artery and accompanying veins as the pedicle for the graft; later a technique using collateral vessels in the arm has been favored. Although functional elbow flexion has been regained in the majority of patients, recovery of function into the hand has been disappointing. Although it cannot be proved that results are better than when conventional sural nerve grafts are performed, the authors believe that this is the case. The vascularized ulnar nerve graft (VNG) is indicated in more severe injuries of the brachial plexus, where preganglionic injury to the eighth cervical and first thoracic nerves is proven, where the gap between nerve stumps is long, and when the presence of two or three proximal stumps allows the opportunity for extensive repair.

Trans-oral approach to the upper cervical spine. A report of 16 cases.

We report 16 cases in which the upper cervical spine was approached through the mouth for operative decompression and stabilisation, with or without removal of diseased tissues. The indications are discussed and the technique is described. Results are compared with those of other reported series. We believe that this operation has a place in the treatment of certain conditions affecting the upper part of the cervical spine and the foramen magnum, with or without involvement of the medulla and spinal cord.

Watson-Jones Lecture, 1976. Some lesions of the brachial plexus.

Three types of lesion of the brachial plexus are discussed: entrapment syndrome; tumours; and traumatic lesions. In the first the importance of the pathological anatomy is stressed; in the second the rewarding results of accurate diagnosis and careful treatment are noted; and in the third the expanding possibilities of neural reconstruction and of specific treatment for pain are described.

Reaching midlife and older smokers: tailored interventions for routine medical care.

BACKGROUND: Although older adults can achieve significant health benefits from smoking cessation, few programs have specifically targeted this population. This study tested the effectiveness of an office-based smoking cessation program tailored to midlife and older smokers. METHODS: This paper describes a randomized controlled trial comparing usual care with physician-delivered brief quit-smoking advice and counseling for midlife and older smokers (ages 50-74). Outpatient medical practices assigned to the Immediate Intervention (experimental) condition were trained to deliver brief quit-smoking advice and counseling. Delayed Intervention (control) practices followed usual care procedures. Thirty-nine practices accruing five or more patients per practice were included in the analyses. RESULTS: Using conservative measure of quitting, self-reported quit rates at 6-month follow-up were 15.41% for the Immediate Intervention group versus 8.16% of subjects in the Delayed Intervention group (P < 0.005). Baseline subject (N = 659) characteristics related to 6-month abstinence included number of previous quit attempts, quitting for 24 hr in the past year, desire to quit, confidence in quitting, perceived health benefits, and lower nicotine dependence. CONCLUSIONS: Smoking abstinence was significantly increased by training physicians and key office and clinical staff to intervene with older smokers. Brief interventions are tailored to this age cohort can be successfully and efficaciously integrated into routine care.
