The purpose of this study was to evaluate the effects of two alternative chemotherapy regimes on the quality of life (QoL) of patients with advanced breast cancer. In a multicentre trial, 283 patients were randomised to receive either docetaxel (T) or sequential methotrexate and 5-fluorouracil (MF). QoL was assessed at baseline and before each treatment using the European Organization for Research and Treatment of Cancer (EORTC) Quality of Life Questionnaire (QLQ-C30). Initial compliance in the QoL study was 96% and the overall compliance 82%. QoL data were available for 245 patients (T 130 and 115 MF). Both treatment groups showed some improvement in emotional functioning during treatment, with a significant difference favouring the MF group at treatment cycles 5 and 6. In the T group, the scores on the other functional scales remained stable throughout the first six cycles. There were significant differences favouring the MF group on the social functioning scale at treatment cycle 6 and on the Global QoL scale at treatment cycles 5 and 6. On most symptom and single-item scales there were no statistically significant differences between the groups. However, at baseline, the T patients reported more appetite loss, at treatment cycles 2-4, the MF patients reported more nausea/vomiting, and at treatment cycle 6, the T patients reported more symptoms of fatigue, dyspnoea and insomnia. There were no statistically significant differences between the groups in the mean change scores of the functional and symptom scales. Interindividual variance was, however, larger in the T group. Differences in QoL between the two treatment groups were minor. Hence, given the expectancy of comparable QoL outcomes, the choice of treatment should be made on the basis of the expected clinical effect.

The aim of the project was to identify clinical and quality of life (QL) factors that together predict survival and response to chemotherapy in advanced breast cancer. Potential prognostic factors were studied in 187 women with baseline QL data from a trial of paclitaxel versus doxorubicin as first-line chemotherapy. Demographic and clinical factors studied were age, performance status, dominant site of disease and preceding disease-free interval (DFI). Factors from the EORTC QLQ-C30 were all function scales, fatigue, nausea/vomiting, pain, dyspnoea, insomnia, loss of appetite and global QL. The proportional hazards regression model with stratification for treatment, and the logistic regression model adjusting for treatment arm were used for univariate and multivariate analyses of survival and response to treatment, respectively. For survival, multiple sites of visceral disease, pain, global QL and fatigue were significant prognostic factors in the univariate analysis. The final multivariate model predicted poor survival with multiple sites of visceral disease (P=0.003), DFI </=2 years (P=0.026) and pain (P=0.003). For response, age, dyspnoea, fatigue and global QL were significant predictive factors in the univariate analysis. The final multivariate model for response selected DFI (P=0.009), multiple sites of visceral disease (P=0.037) and dyspnoea (P=<0.001) using forward selection, but model instability was indicated by the inclusion of fatigue and emotional function in the final model when backward selection was used. In addition to known clinical factors, patient-assessed QL variables appear to be prognostic for survival and response to chemotherapy in women with advanced breast cancer. However, identification of prognostic factors from responses to questionnaires may be unstable, and their reliability and clinical utility should be tested prospectively.

This study assessed sedation in terminal cancer patients in terms of three characteristics: frequency; relationship to intractable symptoms; and the extent to which medical staff, family, and patients found sedation to be ethically acceptable and efficacious. Two hundred seventy-six consecutive patients, who were admitted to the palliative care unit of National Taiwan University Hospital in Taiwan between August 1998 and the end of May 1999, were enrolled. A recording form was completed every day. This included demographic data, pain and common symptom scores, and the use of sedation in the terminal phase. Seventy (27.9%) of 251 patients who died received sedation. Sedation was administered to relieve agitated delirium in 40 (57.1%), dyspnea in 16 (22.8%), severe pain in 7 (10%) and insomnia in 5 (7.2%). The drugs used for sedation were haloperidol in 35 (50%), midazolam in 17 (24.3%), and rapidly increasing dosage of morphine in 9 (12.9%). In fewer than half (42.9%) of the patients, sedation was with the consent of both patient and family, and half (50%) had the consent of family alone. The overwhelming majority of medical staff and family felt the decision to use terminal sedation was ethically acceptable. There was no significant difference in survival time between sedated and non-sedated patients (28.49 vs. 24.71 days, t = -0.791, P = 0.430). Positive ethical acceptability and higher satisfaction with symptom control with terminal sedation were found in both medical staff and family in this study. Further work is needed to find the most appropriate time of intervention and to improve management of refractory symptoms in dying patients.

The extent to which a chronic obstructive pulmonary disease (COPD) patient is impaired in health-related quality of life (HRQoL) is only to a small extent reflected in clinical and demographical measures. As the influence of comorbidity on HRQoL is less clear, we investigated the added value of 23 common diseases in predicting HRQoL in COPD patients with mild to severe airways obstruction. COPD patients from general practice who appeared to have an forced expiratory volume in 1 sec/inspiratory vital capacity (FEV1/IVC) < predicted -1.64 SD, FEV1 <80% predicted, FEV1 reversibility < 12% and a smoking history, were included (n=163). HRQoL was assessed with the short-form-36 (SF-36) and the presence of comorbidity was determined by a questionnaire, which asked for 23 common diseases. All domains of the SF-36 were best predicted by the presence of three or more co-morbid diseases. FEV1 % predicted, dyspnoea and the presence of one or two diseases were second-best predictors. Co-morbidity explained an additional part of the variance in HRQoL, particularly for emotional functioning (delta R2=0.11). When individual diseases were investigated, only insomnia appeared to be related to HRQoL. As HRQoL is still only partly explained, co-morbidity and other patient characteristics do not clearly distinguish between COPD patients with severe impairments in HRQoL and COPD patients with minor or no impairments in HRQoL. Therefore, it remains important to ask for problems in daily functioning and well-being, rather than to rely on patient characteristics alone.

A case of amyotrophic lateral sclerosis (ALS) diagnosed by sleep-disordered breathing is described. The patient's chief complaints were insomnia and nocturnal dyspnea after taking a hypnotic drug. On examination, he showed restrictive ventilatory impairment, alveolar hypoventilation and hypoxia. Polysomnographic examination revealed marked hypoxia during REM sleep periods, decreased duration of REM sleep periods, and increased sleep disruption. Amyotrophic lateral sclerosis was diagnosed by the neurological finding of paraspinal muscle weakness and neurogenic changes revealed by needle electromyography and muscle biopsy. The daytime and nocturnal respiratory insufficiency improved after nasal bilevel positive airway pressure therapy. Amyotrophic lateral sclerosis should be suspected as a cause of insomnia and nocturnal dyspnea.

Most patients with advanced cancer develop diverse symptoms that can limit the efficacy of pain treatment and undermine their quality of life. The present study surveys symptom prevalence, etiology and severity in 593 cancer patients treated by a pain service. Non-opioid analgesics, opioids and adjuvants were administered following the WHO-guidelines for cancer pain relief. Other symptoms were systematically treated by appropriate adjuvant drugs. Pain and symptom severity was measured daily by patient self-assessment; the physicians of the pain service assessed symptom etiology and the severity of confusion, coma and gastrointestinal obstruction at each visit. The patients were treated for an average period of 51 days. Efficacy of pain treatment was good in 70%, satisfactory in 16% and inadequate in 14% of patients. The initial treatment caused a significant reduction in the average number of symptoms from four to three. Prevalence and severity of anorexia, impaired activity, confusion, mood changes, insomnia, constipation, dyspepsia, dyspnoea, coughing, dysphagia and urinary symptoms were significantly reduced, those of sedation, other neuropsychiatric symptoms and dry mouth were significantly increased and those of coma, vertigo, diarrhea, nausea, vomiting, intestinal obstruction, erythema, pruritus and sweating remained unchanged. The most frequent symptoms were impaired activity (74% of days), mood changes (22%), constipation (23%), nausea (23%) and dry mouth (20%). The highest severity scores were associated with impaired activity, sedation, coma, intestinal obstruction, dysphagia and urinary symptoms. Of all 23 symptoms, only constipation, erythema and dry mouth were assessed as being most frequently caused by the analgesic regimen. In conclusion, the high prevalence and severity of many symptoms in far advanced cancer can be reduced, if pain treatment is combined with systematic symptom control. Nevertheless, general, neuropsychiatric and gastrointestinal symptoms are experienced during a major part of treatment time and pain relief was inadequate in 14% of patients. Cancer pain management has to be embedded in a frame of palliative care, taking all the possibilities of symptom management into consideration.

High-altitude heart disease, a form of chronic mountain sickness, has been well established in both Tibet and Qinghai provinces of China, although little is known regarding this syndrome in other countries, particularly in the West. This review presents a general overview of high-altitude heart disease in China and briefly summarizes the existing data with regard to the prevalence, clinical features, and pathophysiology of the illness. The definition of high-altitude heart disease is right ventricular enlargement that develops primarily (by high-altitude exposure) to pulmonary hypertension without excessive polycythemia. The prevalence is higher in children than adults and in men than women, but is lower in both sexes of Tibetan high-altitude residents compared with acclimatized newcomers, such as Han Chinese. Clinical symptoms consist of headache, dyspnea, cough, irritability, and sleeplessness. Physical findings include a marked cyanosis, rapid heart and respiratory rates, edema of the face, liver enlargement, and rales. Most patients have complete recovery on descent to a lower altitude, but symptoms recur with a return to high altitude. Right ventricular enlargement, pulmonary hypertension, and remodeling of pulmonary arterioles are hallmarks of high-altitude heart disease. It is hoped that this information will assist in understanding this type of chronic mountain sickness, facilitate international exchange of data, and stimulate further research into this poorly understood condition.

Sleep-disordered breathing may be present in patients with degenerative diseases affecting the brainstem. Indeed, this last structure contains the executive system of rapid eye movement (REM) sleep (tegmentum of the pons), of respiratory drive (medulla oblongata and pons) and motor neurons of upper airways dilators (fifth, seventh, ninth, tenth and twelfth cranial roots). Patients with Parkinson's disease suffer frequently from insomnia, partly caused by nocturnal motor disability, and from REM sleep behavior disorder. In 20 percent of the patients, excessive daytime sleepiness is caused by a sleep apnea syndrome, with a partly levodopa-dependent upper airway dysfunction. In 40 percent of the patients, sleepiness mimics a secondary narcolepsy and may be associated with hypnagogic hallucinations. During supranuclear palsy, REM sleep is progressively curtailed with rare sleep-disordered breathing. Patients with multiple systemic atrophy may present a nocturnal stridor caused by laryngeal palsy and benefit from tracheotomy or continuous nasal positive airway pressure. Seldom sleep and respiratory studies in genetic ataxic diseases suggest a normal respiratory drive, occasional diaphragmatic dysfunction and night hypopneas. During amyotrophic lateral sclerosis, the progressive loss of phrenic nerve leads to a diaphragmatic dysfunction, dyspnea and a lesser survival. Adequate ventilation is jeopardized during REM sleep with a consequent loss of this state.

Hwa-Byung (HB) has been categorized as a Korean culture-bound syndrome that refers to insidious, long-standing, serious discontent that is projected into the body and is manifested by numerous symptoms such as insomnia, fatigue, panic, palpitations, dyspnea, and others. This study was designed to investigate the prevalence rate of HB in Korean women, validate the predominant symptoms of HB, and validate the related sociodemographic factors and lifestyle factors that differentiate women with HB from those without HB. A total of 2,807 women ages 41 to 65 years were recruited from seven metropolitan areas and six provinces in Korea. The prevalence rate of women who designated themselves as having experienced HB was 4.95%. The rates were higher in women of low socioeconomic status, living in rural areas, among the divorced or separated, smokers, and drinkers. A set of 31 HB symptoms differentiated the potential HB women from the non-HB women.

People exposed to high altitudes often experience somatic symptoms triggered by hypoxia, such as breathlessness, palpitations, dizziness, headache, and insomnia. Most of the symptoms are identical to those reported in panic attacks or severe anxiety. Potential causal links between adaptation to altitude and anxiety are apparent in all three leading models of panic, namely, hyperventilation (hypoxia leads to hypocapnia), suffocation false alarms (hypoxia counteracted to some extent by hypocapnia), and cognitive misinterpretations (symptoms from hypoxia and hypocapnia interpreted as dangerous). Furthermore, exposure to high altitudes produces respiratory disturbances during sleep in normals similar to those in panic disorder at low altitudes. In spite of these connections and their clinical importance, evidence for precipitation of panic attacks or more gradual increases in anxiety during altitude exposure is meager. We suggest some improvements that could be made in the design of future studies, possible tests of some of the theoretical causal links, and possible treatment applications, such as systematic exposure of panic patients to high altitude.
