A newly devised speech accumulator.
Voice therapy is often most effective for treating patients with vocal cord polyp, polypoid degeneration and singer's nodule. However, little is known about the total speaking times in 1 day, the ratio of speech per hour and the sound level during speech, in individual patients. If these parameters can be readily detected, it could be clarified as to how speaking times or patterns are related to a particular voice disorder and/or what instruction a doctor had given a patient. We devised a speech accumulator which records the vibration time of the vocal cords by a small contact microphone attached to the neck, but does not record the actual speech, thus monitoring the privacy of the individual. The time of speech, at any sound level can be read digitally, at any time. This system was clinically used for 11 patients and proved to be most useful. The longest speaking time in 1 day was 182 min, for a bus guide, and the shortest time was 33 min for an office clerk.

[Clinical effect of cefotiam on otorhinolaryngologic infections].
The clinical effectiveness and safety of cefotiam (CTM) in infectious diseases in the field of otorhinolaryngology was evaluated from 30 patients (otitis media 18, pharyngeal infection 4, chronic paranasal sinusitis 1, esophagitis 1, acute bronchitis 1, others 4). Side effect (fever, nausea) was found in a 14 years old male patient. Skin test revealed positive in 1 patient. These cases were excepted from evaluating clinical effectiveness of CTM. In 28 patients, the overall ratio of clinical effectiveness was 60.7%. In patients of otitis media, the clinical effectiveness ratio was 41.2%, whereas the ratio was 75.0--100% in patients of other diseases. In particular, the clinical effect was fair or poor in patients to whom the drug was given only once a day. These results suggest that this chemotherapeutic drug should be administered at least twice a day, particularly to the patients of otitis media. The bacteriological response to CTM was evaluated from 53 strains, isolated from 28 patients before treatment. Eradication rate of bacteria was 60.4%. No abnormal laboratory findings, relating to the drug, were observed after treatment.

Biofeedback therapy for spastic dysphonia.
Spastic dysphonia is a disorder of phonation which is characterized by a strained, creaking, and choked vocal attack, a tense and squeezed voice sound. Spastic dysphonia in a functional voice disorder can be classified into two types from the viewpoint of activities of the extrinsic and intrinsic laryngeal muscle groups. A functional voice disorder pertaining to abnormal activities of the intrinsic and extrinsic laryngeal muscles results in spastic dysphonia. The adductor spastic dysphonia may be due to abnormal actions of the intrinsic laryngeal muscles as such is relieved by sectioning of the recurrent nerve, while spastic dysphonia mainly dealing with the extrinsic laryngeal muscles is relieved by relaxation on monitoring an electromyographic feedback system. Within 3 months we encountered two patients whose extrinsic laryngeal muscles were hyperactive on phonation. A trial on injection of lidocaine into extrinsic laryngeal muscles made their muscles relax. So, biofeedback therapy of relaxation was began using a monitoring system of EMG burst regarding to hypertonicity of the extrinsic laryngeal muscles. Normal vocal abilities were recovered using a biotrainer as a monitoring device of electromyographic feedback.

[Clinical study of cefsulodin on Pseudomonas aeruginosa infections in otorhinolaryngology].
The clinical effect of cefsulodin (CFS) on Pseudomonas aeruginosa infections in otorhinolaryngology was studied in 10 patients. The overall clinical effectiveness was 80% (excellent 2, good 6, poor 2). Eradication rates of P. aeruginosa was 60%. No side effect and positive skin test were found in any cases. Examination of laboratory data before and after the administration revealed no abnormal findings in every cases.
