Diagnosis of orbital tumors by aspiration biopsy guided by computerized tomography.

Thin-needle aspiration biopsy (TNAB) was performed on 22 patients with orbital tumors. Nine patients were studied before the introduction of computed tomography (CT) and only two cytologic diagnoses could be established. Thirteen aspiration biopsies guided by CT were successful. The technique of the CT-guided TNAB of orbital tumors is described. The cytologic features combined with the clinical data made it possible to diagnose precisely 10 malignant orbital tumors that were either metastatic or primary. Two meningiomas and one abscess were also identified. There were no complications. The TNAB of orbital tumors under CT guidance appears to offer several significant benefits to the patients.

Dysarthria in adults: physiologic approach to rehabilitation.

A case study is used to illustrate a physical approach to the speech rehabilitation of adults with dysarthria. The approach emphasizes the component-by-component analysis of the peripheral speech mechanism, where the selection and sequencing of treatment procedures follow directly from the physiologic nature and severity of involvement in each component. The selection and sequencing of procedures also are conditioned by the inherent physical interdependencies of these component parts. Several biofeedback procedures of our own are incorporated that have not been reported previously. The case illustration is of a young man injured in an auto accident whose speech intelligibility improves from approximately 5-10% to 95% during the rehabilitation period. Effects of treatment upon individual components of the speech mechanism are illustrated.

EMG feedback and recovery of facial and speech gestures following neural anastomosis.

A case report is presented of an attempt to increase muscle activity during nonspeech and speech activities through surface electromyographic feedback. The subject, a 25-year-old male, had a surgical anastomosis of the seventh cranial to the twelfth cranial nerve five years prior to the initiation of this therapy. The right side of the face was immobile. Frequency analogs of muscle action potentials from the right lower lip during pressing, retraction, eversion, and speech were presented to the subject. His task was to increase the frequency of the tone thereby increasing muscle activity. The subject made substantial improvement in the gestures listed above. Electrodes also were placed in various infraorbital positions for an upper lip lifting task. This gesture was unimproved. Pre- and posttherapy independence of facial gestures from conscious tongue contraction was found. Possible explanations were proposed for (1) increases of muscle activity in the lower lip, (2) lack of change of MAPs in the upper lip, (3) independence of the facial muscle activity from conscious tongue contraction, and (4) effectiveness of this feedback training.

[A case of dysphagia due to dyskinesia of the oesophageal opening (author's transl)].

A case of dysfunctioning of the oesophageal opening is reported. The patient, aged 71 years, had had difficulty in swallowing for a long time, complicated by the recent onset of obvious dysphagia. Radiological examination of the oesophagus revealed the presence of a permanent notch in the posterior wall in the crico-pharyngeal region. The endoscope could not pass through the oesophageal opening but radiocinematography did not reveal any obvious organic lesion. The dysphagia and crico-pharyngeal notch disappeared after myotomy. This case is one the rare examples of pharyngo-oesophageal incoordination wrongly called crico-pharyngeal achalasia, as there does not appear to be any disorder of relaxation of the upper oesophageal sphincter, and this was demonstrated by the postoperative manometric study carried out in our patient.

Acceleration and weakness in parkinsonian dysarthria.

This report presents some of the underlying neuromuscular mechanisms of dysarthric speech production as they are manifested in selected individuals with parkinsonism. Earlier explanations of parkinsonian dysarthria emphasized that the balanced hypertonus of rigidity formed the basis of reduced range of movements in speech. The present data reveal two problems in the neuromuscular control signals that can result in a reduced range of speech movements in the absence of rigidity. These neuromuscular problems are described as acceleration and weakness. The implication of these findings for the evaluation and treatment of parkinsonian dysarthria is discussed.

Vestibular reactions associated with minocycline.

Several recent reports have indicated that minocycline, a drug effective for meningococcal disease prophylaxis, is associated with a high incidence of vestibular side effects. In January 1975, a questionnaire on adverse reactions was completed by all 29 staff members of a North Georgia hospital who had taken minocycline at the recommended dosage after exposure to a suspected meningococcal meningitis case and by 25 age-, sex-, and occupation-matched non-treated controls. In the treated group 86% experienced moderate to severe vestibular symptoms; 84% of the symptomatic persons experienced their onset after one or two doses of 100 mg. Fifty-two percent of the treated staff members stopped taking the medication because of these effects. The symptoms resolved within 48 h after affected persons discontinued the medication. Until the safety of minocycline can be reestablished, rifampin is recommended for meningococcal disease prophylaxis, and alternative drugs are encouraged for other indications.
