Late results of laterofixation in the treatment of bilateral abductor paralysis of the vocal cords: a clinical study with long-term follow-up

Thirty-four patients with bilateral vocal cord abductor paralysis were treated surgically during the period from 1960 to 1979. The main cause of paralysis was thyroid surgery (85%). Woodman's external laterofixation was performed in 31 patients, 1 had laterofixation by laryngofissure and 2 had endoscopic arytenoidectomy. In Woodman's procedure the body of the arytenoid cartilage was removed in 10 cases and mobilized from the cricoarytenoid joint in 21 cases. Thirteen of the 34 patients needed further surgery. Including previously performed procedures in 6 patients, altogether 68 operations were performed and 17 patients (50%) were operated on more than once. The immediate failure rate of laterofixation was 22% but the need for reoperation increased with time and the total failure rate of the method was 44%. Endoscopic arytenoidectomy was successful in 1 of 2 cases as a primary operation and in 3 of 3 cases as secondary operation. Follow-up time ranged from 2 months to 29 years 8 months (mean 15 years 10 months).

Mothers' discrimination of their neonates' cry in relation to cry acoustics: The first week of life

This study investigated the temporal evolution in the discrimination of the newborn's crying by the mother, from the first to the eighth day after birth. The sample included twenty human mothers who had had an uneventful pregnancy, labour and delivery. They were asked to identify the spontaneous cries of their newborn babies from tape-recorded cries containing cries from their own newborn and from three other newborns. On the first day, the percentage of correct answers was 48#pc, then 81 #pc on the eighth day. Two acoustic features that may underlie this discrimination were analyzed: the maximum Fo values and the average number of cry bursts per second. On the seventh day, these two acoustic variables and the discrimination abilities significantly correlate.     

REM sleep behavior disorder and vocal cord paralysis in Machado-Joseph disease.

We evaluated the occurrence of REM sleep behaviour disorder (RBD) and vocal cord abductor paralysis (VCAP) in a group of 9 Machado-Joseph disease (MJD) patients. RBD was diagnosed by clinical history plus audiovisual polysomnography in 4 men and 1 woman (55%). While dreaming, 4 fell out of the bed and the other injured his arms. Laryngoscopy detected bilateral VCAP in 1 patient with stridor who required emergency tracheotomy, and partial vocal cord abductor restriction in 2. RBD and VCAP are two potentially injurious conditions that should be considered part of the clinical spectrum of MJD.

The Relationship Between Psychogenic Cough and the Diagnosis and Misdiagnosis of Asthma: A Review

The differential diagnoses of persistent nonproductive cough include numerous pulmonary and nonpulmonary organic disorders as well as functional illnesses. Many diseases can cause cough, and several studies have shown asthma among the most common etiologies associated with chronic cough in adult nonsmokers, as well as children. Psychogenic cough and its relationship to asthma and other asthma-like illnesses is complex since distinct maladies with similar features may coexist individually or in combination in any given patient. While chronic cough may occur as a sole presenting manifestation of bronchial asthma in all age groups, recent findings suggest that most children with persistent cough without other respiratory symptoms do not have asthma. Since several organic, as well as functional diseases, may present with persistent cough as their sole manifestation in either adults or children, cough should not be used as a single or major determinant to diagnose and treat asthma, especially when empirically focused therapy trials fail. Given the range of illnesses causing cough, no single management guideline can be expected to be universally effective.

Early recognition of newborn goat kids by their mother: II. Auditory recognition and evidence of an individual acoustic signature in the neonate

The vocal recognition of newborn kids by their mother at 2 days postpartum and the possible existence of interindividual differences in the voice structure of newborn kids were investigated in two separate studies. The ability of goats to discriminate between the bleats of their own versus an alien kid was tested at 2 days postpartum in mothers being prevented access to visual and olfactory cues from the young. Goats spent significantly more time on the side of the enclosure from which their own kid was bleating, looked in its direction for longer, and responded more frequently to the bleats of their own than to those of the alien kid (p < 0.05). In the second study, the sonograms of 13 kids, studied from Days 1 to 5, showed significant interindividual differences for the five variables taken into account and on each of the 5 days (duration of bleat, fundamental frequency, peak frequency, and numbers of segments and of harmonics). The potential for individual coding ranged between 1.1 and 4.1, indicating that for some variables variations between individuals were greater than intraindividual variations. Furthermore, when considering the five parameters together, the discriminating scores showed an average of 95% in the 78 combinations of any 2 kids for any given day. Finally, some significant intraindividual differences also were found between days, suggesting ontogenic changes in the characteristics of the kid's voice in early life. Therefore, mother goats are likely to recognize the vocalizations of their 48-hr-old kids, as they show sufficient interindividual variability to allow the existence of individual vocal signatures, even though some of the characteristics of the bleats change rapidly over time.
