To investigate whether the preservation of atrioventricular (AV) synchronization matters for quality-of-life during pacemaker treatment we assessed 17 consecutive patients with high degree AV block and preserved sinus node function in a double-blind, long-term crossover study. A questionnaire with regard to cardiovascular symptoms, sleep disturbances, cognitive functioning, physical ability, social interaction, emotional functioning, and self-perceived health was completed after 2 months of atrial synchronous (DDD) and rate modulated ventricular pacing (VVI,R), respectively. A significant improvement in shortness of breath, dizziness and palpitations as well as an improvement of cognitive functioning was observed during DDD pacing. Nine patients preferred the DDD mode and three the VVI,R mode. The remaining five patients did not express any preference. The preference for the DDD mode was explained by a significant reduction of cardiovascular symptoms and an improved self-perceived health, physical ability, and psychological well-being during DDD pacing. All differences in quality-of-life parameters between the two modes of pacing favored the DDD mode and no adverse effects of this mode were found. Thus, the maintenance of AV synchrony adds further symptomatic relief compared to rate increase alone. The results indicate that DDD pacing is the preferred mode of pacing in patients with high degree AV block and preserved sinus node function.

This study is a prospective, double-masked, randomized, clinical trial to determine the effect of anti-arrhythmic drug therapy on mortality in patients with congestive heart failure and ventricular arrhythmia. Patients will be assigned to receive either amiodarone or placebo. Eligible patients include those with ischemic and nonischemic congestive heart failure (New York Heart Association class III or VI) and with 10 or more ventricular premature beats per hour. All patients must have shortness of breath with minimal exertion or paroxysmal nocturnal dyspnea, a left ventricular internal dimension (LVIDd) by echocardiogram of 55 mm or greater (> or = 55 mm) or a CT ratio of greater than 0.5, and an ejection fraction of 40% of less. Patients will be entered into the study for 2.5 years and followed for an additional 2 years. Drug therapy will be continued for all patients throughout the entire study unless adverse reactions occur that necessitate individualized treatment. The expectation is that 674 patients are to be entered into the study from 25 participating centers. This sample size will allow for the detection of a 33% decrease in 2-year mortality (20% vs. 30%) in the treated patients as compared to those in the placebo group with a power of 0.90 and a two-sided alpha level of 0.05. Intermittent Holter monitoring, radionuclide ventriculograms, pulmonary function tests, echocardiograms, and blood tests, including arterial blood gases, will be required for each patient. The study analysis will address differences in total mortality, cardiac mortality, and sudden cardiac death between patients receiving anti-arrhythmic drug therapy and those receiving placebo. Other factors to be examined include the effects of antiarrhythmic therapy on suppression of arrhythmias, on ejection fraction, and relation of ischemic events to mortality.

A patient presented with shortness of breath without fever, cough or sputum production. The patient was hypoxic without leukocytosis and a chest x-ray film demonstrated a right unilateral pulmonary infiltrate. A chest CT showed a large ascending thoracic aortic aneurysm with dissection. During surgical repair, the aneurysm was noted to be compressing the single right pulmonary vein. The infiltrate resolved postoperatively, and the patient has remained symptom-free for one year.

There were 34 episodes of pneumothorax out of 400 episodes of COPD (i.e. 8.5% of the total) among patients who were admitted to Chulalongkorn Hospital during the period 1982 to 1986; the episodes of pneumothorax occurred among 22 males and one female, with the average age on admission being 64.0 +/- 8.5 years. All patients had a long history of smoking (average 40 years) with a history of recurrent pneumothorax (47.8%) and two episodes of pneumothorax per patient. Since only about one third of our patients had chest pain or positive signs of pneumothorax on physical examination, the possibility of pneumothorax should be considered in every patient who develops sudden and increasing shortness of breath, especially during mechanical ventilation, or even in association with other obvious precipitating factors, e.g. URI. With regard to complications, there were eight, four, two, two and five episodes of severe respiratory failure requiring assisted ventilation, tension pneumothorax, bilateral simultaneous pneumothorax, pneumomediastinum with subcutaneous emphysema, and plural effusion, respectively. The death rate was 23.5 per cent. Patients who had a pneumothorax requiring assisted ventilation or who developed a pneumothorax during assisted ventilation had a grave prognosis because of multiple complications from mechanical ventilation. Two episodes with minimal pneumothoraxes achieved re-expansion after conservative treatment. The treatment required 3.3 days for the lung to fully expand, 9.6 days when the air-leak stopped and the duration of tube drainage was 10.8 days. Our study indicates that the longer the duration of lung collapse the longer the time required for re-expansion of the lung.(ABSTRACT TRUNCATED AT 250 WORDS)

A 53-year-old woman was admitted on 13th October 1988 with symptoms of dry cough and shortness of breath persisting for 1 year. On physical examination, fine crackles were audible over her back. Chest X-ray showed bilateral reticulonodular shadows and collapse of the bilateral lower lobes. Chest CT showed patchy areas of increased density distributed predominantly in the subpleural zone. Laboratory data on admission showed thrombocytopenia, hypergammopathy (IgG, 2044 mg/dl; IgA, 286 mg/dl; IgM, 1645 mg/dl), and positive ANF. Further examinations demonstrated that anti-platelet and anti-centromere antibodies were positive in the serum, and the titer of PA-IgG was high (56 ng/10(7) platelets). Histopathological examination of the open lung biopsy demonstrated honeycombing and thickening of the alveolar walls, with slight infiltration of chronic inflammatory cells. These histopathological findings were comparable with usual interstitial pneumonia. We report a very rare case of chronic interstitial pneumonia complicated by benign monoclonal gammopathy and thrombocytopenia. Although it remains unclear, these abnormalities may have been caused by immunological mechanisms.

A 58-year-old woman was hospitalized because of shortness of breath, cough, weakness, and physical signs suggestive of mitral stenosis. Echo-Doppler examination revealed a left atrial mass. This was removed and turned out to be a fibrosarcoma. Recurrence of the tumor with metastases into the pericardium, thyroid goiter, and left kidney led to the patient's death 6 months later. The clinical and pathological features of our rare case are compared with those in the literature.

The relation of respiratory symptoms and lung function has not been extensively investigated. To determine better the rate of FEV1 decline in subjects reporting persistent wheeze, chronic cough, chronic phlegm, and/or dyspnea, longitudinal data from an adult population sample of 3,948 subjects (1,757 men; 2,191 women) followed for 12 yr were analyzed. At the initial and subsequent follow-up visits, subjects completed a standardized respiratory questionnaire and performed spirometry using the same methods and spirometers. Subjects were categorized based on the presence or absence of self-reported respiratory symptoms (persistent wheeze, chronic cough, chronic phlegm, or shortness of breath) at the initial visit. Six-specific linear regression models were fitted to determine the effect of these respiratory symptoms on lung function. In both men and women, reporting of any respiratory symptoms was associated with both a reduction in initial lung function and more rapid decline in height-adjusted FEV1. Furthermore, after adjustment for height, age, and cigarette smoking, men with cough or phlegm and women with cough alone showed accelerated loss in FEV1. Clinicians should be aware of the predictive value of these respiratory symptoms, because therapeutic intervention may modify the associated decline in lung function.

Thirty young women participated in an experiment in which heart rate, blood pressure, respiration rate, skin conductance level and palmar sweat index were monitored at rest and during the administration of mental arithmetic, mirror drawing and cold pressor tasks. The accuracy of perception of somatic states was estimated by calculating within-subject correlations between four bodily sensations (racing heart, high blood pressure, shortness of breath and sweaty hands) and corresponding physiological parameters, assessed on eight occasions during the experiment. The accuracy of heart rate perception was highest, with a mean correlation between actual heart rate and ratings of racing heart of 0.76 and 66% of participants showing significant within-subject effects. The mean accuracy was 0.55 for systolic blood pressure, 0.48 for respiration rate, 0.47 for skin conductance level, and 0.64 for palmar sweat index. Accurate perception across physiological parameters did not cluster within individuals, and was not dependent on the range either of physiological changes or sensation ratings. Trait anxiety was not significantly associated with accuracy of somatic perception. Subjects with high trait anxiety reported larger increases in shortness of breath during tasks than did low anxious subjects, but this was not reflected in objective physiological measures. Information-seeking coping style, indexed by the monitoring scale of the Miller Behavioral Style Scale, was related to the accuracy of perception of skin conductance level and heart rate. The use of within-subject correlational strategies for assessing individual differences in perception of bodily states is discussed.

A cross-sectional study on tobacco smoking prevalence and related socio-psychological parameters in Moscow school students aged 10-17 was performed. Data from an anonymous self-report (n = 4802) on smoking prevalence was confirmed by special technique--expert assessment. Widespread smoking was found: among male 5th graders (the youngest group) 14.4% are smokers (those who smoked at least 1 cigarette over the past 3 months); among male 10th graders (oldest group) 53.2% smoke; among females these figures were 0.8% for the youngest students and 28.2% for the oldest ones. A significant difference in awareness of smoking health hazards and attitudes towards the habit was shown among school students with various smoking statuses. Complaints about cough and shortness of breath after light physical stress were significantly more prevalent in regular smokers as compared to non-smokers. The possible causal role of some psychological factors in early formation of smoking habit is discussed.

Two men (aged 37 years--patient 1, and 26 years--patient 2), both in good health, had dived as a sport to a depth of 40 and 45 m, respectively, reportedly keeping to the prescribed decompression times on their ascent. Patient 1 immediately developed shortness of breath and pain in the chest, later neurological deficits in both legs, as well as faecal and urinary incontinence. Examination 60 h later revealed paraparesis, increased leg proprioceptor reflexes and paraesthesia below the 10th thoracic vertebra, with abnormal posterior column function. After recompression (hyperbaric oxygenation, 6 treatment sessions of 4 h each over 8 days, as prescribed in US Navy Table No. 6) the signs improved and two months later there were no deficits. Patient 2 developed 30 min after a similar dive painful, doughy swellings and redness over the upper ventral half of the thorax and both upper arms. All signs and symptoms disappeared after recompression treatment (hyperbaric oxygenation for 3 h), begun 28 h after the dive. Previously elevated levels for haemoglobin (18.5 g/dl), haematocrit (0.56) and red blood corpuscles (5.98 x 10(6)/microliters) returned to normal. The described neurological abnormalities are typical for type II, redness and joint pains for type I decompression sickness.
