摘要:

Brain stem evoked response (BER) audiometry presents abnormal findings in patients with acoustic neuromas. The test involves averaging of recordings at the vertex as sound-triggered nerve impulses travel from the cochlea to the brain stem. From the time the sound stimulus arrives at the cochlea until it reaches the first major brain stem synapse (within 10 milliseconds), five major waves have been identified as typical of normal averaged responses. Abnormality in the cochlea or eighth nerve causes specific changes in pattern, primarily in wave latency. These latency shifts can be used to predict the site of the lesion. In evaluating 17 lesions of the cerebellopontine angle, BER audiometry was accurate in the diagnosis of all of the tumors. This diagnostic tool should play a prominent role when acoustic tumor is suspected.

摘要:

The standard preparation for cleansing the colon usually involves dietary restrictions, purgatives, and enemas. This is time-consuming, often uncomfortable, and at times unsuccessful. This study of 37 patients examines the efficacy of saline lavage as an alternative method for cleansing the bowel. Isotonic sodium chloride solution is pased into the gut via a small nasogastric tube. The flush is continued for about four hours, until clear effluent is passed per anus. There were no significant complications or variations in weight or serum electrolyte values. Patient acceptance was generally excellent. In our opinion, this rapid bowel preparation consistently provided a clean bowel so that both bowel preparation and colonoscopy were accomplished the same day.

摘要:

Arthroscopy has benefited greatly by the development of the miniaturized television camera. Not only is televised arthroscopy a valuable teaching aid, but it also promises to shorten and make more efficient many of the necessary operative procedures on the knee. A method for accomplishing this is presented.

摘要:

Using various modalities, we analyzed 110 patients with thoracic outlet compression syndrome who had extensive evaluation. Nerve conduction velocities and Directional Doppler studies are the most useful adjuncts in diagnosis. Diagnosis and selection of the proper treatment of these patients will be outlined.

摘要:

Since the entity of “juvenile melanoma” was first described, many pathologists have been reluctant to diagnose malignant melanoma in childhood by pathologic criteria alone. In this series of 125 cases, pathologic criteria are used to distinguish malignant melanoma of childhood from spindle and epithelioid nevus. Among the patients reviewed, 110 cases (86%) occurred between ages 13 and 20 years, and 15 cases (14%) in children under 12. There were 60 males (54%) and 50 females (46%) in the older age group, and six males (41%) and nine females (59%) in the childhood group. In the 13 to 20 age group, there were 24% head and neck primary melanomas, 38% truncal primaries, 30% limb primaries, and 7% indeterminate, as opposed to 35% head and neck, 23% truncal, and 41% limb in the group under 12. In the 13 to 20 year group, 66% were stage I, 11% stage II, 12% stage III, 2% stage IV and 7% indeterminate while in the 12 and under group, 76% were stage I, 12% stage III, and 12% stage IV. Mortality rates were 49% for the 13 to 20 year group and 60% for the 12 and under group.

摘要:

A number of new tests for detection of small airway disease have been developed in the past several years. It is hoped that these will prove valuable as screening tests to detect those at risk of developing obstructive airway disease. We obtained data on the degree of discrimination of single breath nitrogen studies (CV/VC, CC/TLC, ΔN2/L), air-He studies (Vmax50), and the maximal midexpiratory flow (FEF25–75%) in detecting abnormalities in young smokers. Only the CV/VC and CC/TLC significantly separated smokers from nonsmokers, each revealing 20% abnormal values in smokers.

摘要:

Nuclide brain scanning offers a noninvasive means of obtaining dynamic information about intracranial disease. Lesions which could be missed without the flow study are described, and other instances in which the differential diagnosis is greatly improved by the use of the vascular sequence are demonstrated. We recommend the routine use of the flow study when performing brain scans.
