Suprascapular neuropathy after intensive progressive resistive exercise: case report.

A healthy 30-year-old man developed pain in the posterior shoulder region approximately one month after initiating an intensive weightlifting program to increase upper extremity strength. This program especially emphasized shoulder abduction exercises. The pain intensified as he continued and finally he noted weakness of the involved shoulder, which led him to seek medical advice. Examination was normal except for atrophy of the infraspinatus muscle on the involved side and decreased strength of shoulder abduction and external rotation. Electromyographic examination demonstrated 3+ positive sharp waves in the infraspinatus muscle, delayed conduction to the supraspinatus muscle, and absence of an evoked response to the infraspinatus muscle. Surgical decompression of the suprascapular nerve within the suprascapular notch was then performed. Two weeks after surgery the pain was much less and the conduction velocities had improved. Eight months after surgery the patient was free of pain, the conduction velocities had returned to normal, and electromyography revealed reinnervation of the denervated muscle fibers. Intensive shoulder exercise, especially involving repeated forceful abduction movements, should be considered in the etiology of suprascapular neuropathy.

Health practices, risk factors, and chronic disease in Tecumseh.

Seven health practices previously found to be associated with a self-report index of good health and with lower mortality in the Alameda County studies were related to several measures of health in a cohort of 880 men and 973 women, ages 35-69, who were participants in the Tecumseh Community Health Study. The health measures were prevalence of three diagnoses--coronary heart disease (CHD), hypertension, and chronic bronchitis--and levels of five risk factors--systolic and diastolic blood pressures, serum total cholesterol, blood glucose, and FEV1. Four of the practices--desirable relative weight, physical activity, never having smoked, and moderate or no alcohol drinking--were associated significantly with one or more of the health measures. Eating breakfast, limited between-meal eating, and sleeping 7 or 8 hr were not related to the health measures. Combining all seven health practices into an index produced a measure that was more strongly associated negatively with CHD prevalence than was any one of the component practices. However, the index was no more strongly associated with any of the other health measures than were the relevant separate practices. Desirable weight was more highly associated (negatively) with hypertension and blood pressure than the index was, as was never having smoked with chronic bronchitis (negatively) and FEV1 (positively).

A Comparison of Soybean Agglutinin in Cultivars Resistant and Susceptible to Phytophthora megasperma var. sojae (Race 1).

The amount of soybean agglutinin (SBA) detectable by radioimmunoassay in seeds of resistant cultivars to Phytophthora megasperma var. sojae was approximately twice that of susceptible cultivars. SBA was preferentially released at earlier times (6-9 hours) and in higher amounts in the imbibate from resistant cultivars as compared to susceptible cultivars. The lectin in the imbibate was immunologically identical to the seed lectin, indicating little or no proteolysis had occurred, and was active in hemagglutination. Binding of fluorescein isothiocyanate-labeled SBA to mycelial cell walls could be abolished by adding N-acetyl galactosamine or galactose. Purified SBA at concentrations of 150 to 300 micrograms inhibited mycelial growth by 50%, and the imbibate from Govan (resistant) cultivar was more inhibitory than the imbibate from Shore (susceptible) cultivar. Removal of SBA from the imbibate by affinity chromatography abolished the inhibition of mycelial growth, but the inhibition could be recovered from the eluant containing lectin.

Immediate postembolization excision of glomus jugulare tumors: advantages of new combined techniques.

Preoperative percutaneous transfemoral catheter embolization of feeding vessels in glomus jugulare tumors, followed by immediate application of standard surgical techniques, presents the treatment of choice, allowing meticulous microsurgery with virtually complete hemostasis. Therefore, the surgeon can operate in a bloodless environment throughout the compressed and intricate anatomic field, amidst such important yet vulnerable structures as cranial nerves, inner ear, carotid artery, jugular bulb, venous sinuses, and dura, while reducing surgical error and functional deficit for the patient. Review of the last 11 cases of glomus jugulare tumors at UCLA shows that even extensive Alford grade 2 tumors of the middle ear, jugular bulb, and mastoid had only minor blood losses with this combined technique of embolization-immediate surgery, as compared with earlier surgical methods. Pertinent literature on glomus jugulare and its treatment is reviewed. Combined embolization and immediate surgery offer the best approach for treatment of resectable glomus jugulare tumors.

Local anesthesia for suspension microlaryngoscopy.

Despite the strong trend toward use of general anesthesia for laryngoscopy, local anesthesia retains inherent advantages from the standpoint of patient safety and maintenance of physiologic function of the larynx during endoscopy. Topical anesthesia produces incomplete sensory blockade and is unsatisfactory for suspension laryngoscopy. A method of infiltration anesthesia is described whereby profound anesthesia of the base of the tongue, valleculae, and larynx can be achieved to allow suspension laryngoscopy.

Meniere's disease: clinical course, auditory findings, and hearing aid fitting.

Results of a five-year longitudinal study of Meniere's disease in 95 patients is presented. Tests utilized in diagnosis and in determining specific etiology are described. Clinical treatment for patients with Meniere's disease symptoms is discussed. Auditory test results for 101 ears are analyzed. The fluctuating nature of the hearing loss, the poor discrimination for speech, and the limited tolerance for amplification because of the narrow dynamic range present significant problems in utilization of hearing aids for patients with Meniere's disease. A practical approach is suggested for the fitting of hearing aids for these patients.
