20 patients, aged between 31 and 71, have been treated. All were hospitalized because of acute or chronic broncho-pneumopathy and have been administered 4-carbomethoxythiazolidine at a dosage of 300 mg/d. in association with the common antibiotic or chemiotherapic treatments. Every day all symptoms have been registered (asthenia, cephalea, sibiluses, rhoncuses, rales, inspiratory and expiratory dyspnea). Before and after the treatment some respiratory functioning tests have been performed, including the VEMS and VEMS/CV determination. A further study on the distribution of the inhaled air has been carried out, as well as on the ventilation/perfusion ratio by means of He and CO2 curves. At the beginning and at the end of the TMC treatment some hematiobiologic tests have been carried out, including: haemochromo with leukocytic formula, blood platelets counting, VES, glycemia, azotemia, transaminase, alkaline phosphatase, total bilirubinaemia, prothrombinic activity and determination of urine's specific weight. The pulmonary symptomatology (cough, sibiluses, rhoncuses, rates, inspiratory and expiratory dyspnea), was markedly reduced. Even if, as for the preliminary character of the experiment, we can state that 4-carbomethoxythiazolidine is a drug with an outstanding level of tolerance.

Sudden unexplained death may be seen with treatment of craniovertebral anomalies and surgery of the upper cervical spine. Death is due to sleep-induced apnea, premonitored by periods of confusion, lethargy, and asthenia. There may be associated hypotension, bradycardia, hyponatremia, hypothermia, inappropriate antidiuretic hormone secretion, and difficulty in micturition. The potential for respiratory failure may be predicted if a CO2 response test demonstrates an attenuated or abnormal response. Apnea during sleep may be reversed by arousal or may require ventilatory support for a period of time. The condition is self-limiting, but remains the major life-threatening complication. Both apnea and autonomic dysfunction are treatable and curable with appropriate diagnosis and management.

This article has dealt with the psychophysiological phenomenon known as "hyperventilation syndrome." Published research on this syndrome dates back at least a century to Da Costa's classic investigation involving "soldier's heart". Various labels such as "effort syndrome," "anxiety neurosis," "neurocirculatory asthenia," "vasoregulatory asthenia," and "irritable heart," have been employed over the past century to describe this syndrome. The use of different labels to describe this syndrome seems to be inappropriate. While the symptoms associated with these diagnostic labels appear to be remarkably similar, the treatment for the syndrome often differs as a function of the diagnostic label. Symptoms include breathlessness or dyspnea with effort, parathesia, trembling, tachycardia, tetany, carpopedal spasms, and convulsions in the case of a full-blown attack. Hyperventilation, a normal consequence of vigorous exercise and/or high temperatures, can often occur in some individuals for no apparent reason. Hyperventilation, and the resulting physiological changes, are often associated with decrements in psychomotor performance along with increased error rates. The symptoms which characterize the hyperventilation syndrome can be readily produced in certain "types" of individuals within minutes by requiring the individual to overbreathe or through introduction of a CO2 challenge. The symptoms, once produced, can be quickly reversed by placing a paper sack over the subject's head and requiring him/her to rebreathe expired air. Overbreathing and CO2 challenges do not, however, produce full-blown hyperventilatory attacks in most individuals. That is, some individuals or "types" appear to be especially sensitive to the effects of overbreathing and/or CO2 loading.(ABSTRACT TRUNCATED AT 250 WORDS)

Quality of voice after treatment for T1A glottic squamous cell carcinoma was studied in two matched groups of males treated either with CO2 laser cordectomi (n = 18, mean age 65.2 years) or with full dose radiotherapy (n = 18, mean age 65.1 years). All patients had histologically verified invasive squamous cell carcinoma. Fifteen male patients (mean age 63.9 years) without laryngeal disorders were used as controls. Voice recordings prior to treatment, and both at 3 months and at 2 years after completed treatment were analyzed. Acoustic measures of shimmer, jitter, breathiness, harmonic-to-noise ratio and fundamental frequency (F0) average were calculated with the Soundscope program. Two plain measures were also used: time required to read a running speech voice sample, and number of breaths. Perceptual voice analysis was performed blindly by two groups of listeners, Group A (4 experienced listeners) and Group B (4 naive listeners). Group A estimated quality of voice according to a modified GRBAS score, whereas Group B estimated Grade only. We found voice quality both at 3 months and at 2 years after radiotherapy to be significantly better than after laser treatment, as assessed by the acoustic variables breathiness, jitter, F0 average, running speech voice sample reading time and number of breaths. The perceptual variables Grade (Group A and B), Breathiness, Asthenia and Strain were also significantly better after radiotherapy.

Weakness, easy fatiguing, and lack of endurance are commonly perceived by patients with Parkinson's disease (PD). Although the slowed motor repertoire in PD may underlie these experiences, other abnormalities in skeletal muscle utilization also may be involved. We investigated whether an index of metabolic efficiency during a continuous exercise task, the latency until anaerobic threshold (AT), is altered by L-DOPA (LD). While pedalling a bicycle ergometer against a uniform workload, subjects were monitored for expired O2 and CO2. As compared to an unmedicated state, LD treatment delayed AT by a mean (+/-SE) of 5.67 +/- 0.89 to 6.62 +/- 1.23 min (p < 0.05), paired t test). Subjects did not differ in their perceived exertion upon reaching AT. With relief of parkinsonism by LD, the efficiency of energy utilization is also increased in exercised skeletal muscle.

Several variables have been identified as risk factors for conversion to overt psychosis in ultra-high risk for psychosis (UHR) individuals. Although almost two-thirds of them do not experience a transition to psychosis, they still exhibit functional disabilities. Other subjective developmental features may be useful for a more precise identification of individuals at UHR. Avoidant behaviors are consistently reported in schizophrenia and in UHR individuals and may be the reflection of a pattern of personality. Thus, personality features in UHR individuals deserves further research. The objective of the present study was to compare temperament and character dimensions between UHR individuals, patients with schizophrenia and healthy controls. One hundred participants (25 UHR individuals, 25 schizophrenia patients and 50 control subjects) where evaluated with the Temperament and Character Inventory-Revised (TCI-R). Univariate ANOVAs followed by Bonferroni tests were used. UHR individuals and schizophrenia patients exhibited higher levels of Harm Avoidance (HA) when compared to control subjects. For HA1 Anticipatory worry vs Uninhibited optimism and HA4 Fatigability & asthenia, UHR and schizophrenia groups showed similar scores and both groups were higher compared to control subjects. With respect to Cooperativeness (CO), UHR and schizophrenia reported lower scores than control subjects, in particular CO2 Empathy vs Social disinterest and CO3 Helpfulness vs unhelpfulness. This study replicates and extends the consideration of HA as a psychopathological related endophenotype and gives us further information of the possible role of personality features in the expression of some of the social dysfunctions observed both in prodromal subjects and schizophrenia patients.
