Posterior laryngitis: a disease with different aetiologies affecting health-related quality of life: a prospective case-control study.

BACKGROUND: Laryngo-pharyngeal reflux (LPR) is assumed to be the most common cause of posterior laryngitis (PL). Since LPR is found in healthy subjects, and PL patients are not improved by acid-reducing therapy, other aetiologies to PL must be considered. The aims of this study in PL were to investigate the prevalence of acid reflux in the proximal oesophagus and functional gastrointestinal symptoms, to analyse motilin levels in plasma, and to assess health-related quality of life (HRQOL) before and after treatment. METHODS: Forty-six patients (26 women), with verified PL, median age 55 (IQR 41-68) years, were referred to oesophago-gastro-duodenoscopy and 24-h pH monitoring. Plasma motilin was analysed. The 36-item Short-Form questionnaire was completed at inclusion and at follow-up after 43±14 months, when also the Visual Analogue Scale for Irritable Bowel Syndrome was completed. Values were compared to controls. Treatment and relief of symptoms were noted from medical records. RESULTS: Thirty-four percent had proximal acid reflux and 40% showed signs of distal reflux. Ninety-four percent received acid-reducing treatment, with total relief of symptoms in 17%. Patients with reflux symptoms had lower plasma motilin levels compared to patients without reflux symptoms (p = 0.021). The HRQOL was impaired at inclusion, but improved over time. Patients, especially men, had more functional gastrointestinal symptoms than controls. CONCLUSIONS: This study indicates that a minority of patients with PL has LPR and is cured by acid-reducing therapy. Disturbed plasma motilin levels and presence of functional gastrointestinal symptoms are found in PL. The impaired HRQOL improves over time.

Posterior laryngitis: a study of persisting symptoms and health-related quality of life.

Posterior laryngitis is a common cause of chronic cough, hoarseness, voice fatigue and throat pain. The aim of the present study was to examine how patients with posterior laryngitis have been examined, treated and followed up, and to assess their present health-related quality of life (HRQOL). Patients treated for posterior laryngitis at consultation at the ear-, nose- and throat clinic during 2000-2008 were contacted by mail. The letter contained questionnaires addressing the current symptoms and medication, and the HRQOL 36-item short-form questionnaire (SF-36). Medical records were scrutinized. One hundred and twenty-two patients with verified signs and symptoms of posterior laryngitis were included. Forty percent of the patients had been treated for acid-related symptoms prior to consultation. The most common symptoms at the time of consultation were the sensation of hoarseness (women 40 %, men 37 %), globus (women 35 %, men 33 %) and cough (women 33 %, men 26 %). The most frequent diagnosis was gastro-oesophageal reflux disease. Ninety percent of the women and 92 % of the men were treated with proton pump inhibitors (PPIs). At the time of study, 63 % of the patients still had symptoms. The results of the SF-36 questionnaire showed significantly lower HRQOL for women. Patients with posterior laryngitis present varying symptoms, and are often not adequately treated or followed up. When PPI treatment fails, other aetiologies of their complaints, such as visceral hypersensitivity, weakly gaseous acid reflux or non-acid reflux are not considered. Symptoms from posterior laryngitis have a negative impact on the HRQOL for women.

Computed tomography measurements of different dimensions of maxillary and frontal sinuses.

BACKGROUND: We have previously proposed the use of Doppler ultrasound to non-invasively stage sinus infection, as we showed that acoustic streaming could be generated in nonpurulent sinus secretions and helped to distinguish it from mucopurulent sinus secretions. In order to continue this development of a clinically applicable Doppler equipment, we need to determine different dimensions of the paranasal sinuses, especially the thickness of the anterior wall of the maxillary sinus (at the canine fossa). To the best of our knowledge, this is the first report on the thickness of the canine fossa. This study aimed to (a) estimate different dimensions of the maxillary and frontal sinuses measured on computed tomography (CT) of the head, (b) define cut-off values for the normal upper and lower limits of the different measured structures, (c) determine differences in age, side and gender, (d) compare manually and automatically estimated maxillary sinuses volumes, and (e) present incidental findings in the paranasal sinuses among the study patients. METHODS: Dimensions of 120 maxillary and frontal sinuses from head CTs were measured independently by two radiologists. RESULTS: The mean value of the maxillary sinus volume was 15.7±5.3 cm3 and significantly larger in males than in females (P=0.004). There was no statistically significant correlation between the volume of maxillary sinuses with age or side. The mean value of the bone thickness at the canine fossa was 1.1±0.4 mm. The automatically estimated volume of the maxillary sinuses was 14-17% higher than the calculated volume. There was high interobserver agreement with regard to the different measurements performed in this study. Different types of incidental findings of the paranasal sinuses were found in 35% of the patients. CONCLUSION: We presented different dimensions of the maxillary and frontal sinuses on CTs. We believe that our data are necessary for further development of a clinically applicable Doppler equipment for staging rhinosinusitis.

In vitro studies and safety assessment of Doppler ultrasound as a diagnostic tool in rhinosinusitis.

We have previously proposed the use of Doppler ultrasound to noninvasively stage a sinus infection. In this study, we first investigated the acoustic properties of nonpurulent and mucopurulent sinus secretions. The density, viscosity, speed of sound and attenuation of 18 samples of sinus fluid were examined. We then assessed the safety of the method by determining the temperature increase when ultrasound is transmitted through a bone sample of the same thickness as the anterior wall of the maxillary sinus. As a measure of the probability to generate acoustic streaming, we determined the ratio of sound attenuation over the viscosity of the sinus fluid and compared this with the value obtained from acoustic streaming measurements on a model system. The results indicated that detectable levels of acoustic streaming can be generated in serous sinus fluid, which has a low viscosity, but is very unlikely in mucopurulent secretions. The attenuation of the mucopurulent sinus fluid was 10 times higher than that of the serous cyst fluid, but the viscosity of the mucopurulent secretion was a thousand times higher than that of serous fluid. The safety experiments gave a temperature increase of the bone of <1.5°C at I(spta) of 640 mW/cm(2), below the temperature increase considered to be harmful by the World Federation for Ultrasound in Medicine and Biology.

Health-related quality of life during the last three months of life in patients with advanced cancer.

GOALS OF WORK: The aim of the study was to explore the development of functioning impairments and symptom occurrence during the last months of life of advanced cancer patients. MATERIALS AND METHODS: Self-reported data from 116 patients who all completed the European Organisation for Research and Treatment of Cancer Quality of Life Questionnaire-Core 30 (EORTC QLQ-C30) at 3, 2 and 1 month before death were analysed. MAIN RESULTS: All functioning aspects deteriorated. For physical, cognitive and social function, the most marked changes occurred between 2 and 1 month before death. The proportion reporting serious difficulties with self-care activities increased from 14% to 43%. The most seriously affected activity could not be distinguished from the EORTC QLQ-C30 scores. Levels of fatigue, dyspnoea and appetite loss increased significantly. More than 50% of the patients had severe pain at all assessments, and only a minor number (8%) reported any improvement. CONCLUSIONS: The findings have implications for the planning of care and indicate that further research is required to improve assessment, treatment and follow-up procedures. Adequate pain treatment seems still to be a challenge. Anorexia, fatigue as well as dyspnoea are all symptoms that need further focus.

Characteristics and quality of life of patients who choose home care at the end of life.

Cancer patients with advanced disease and short-survival expectancy were given hospital-based advanced home care (AHC) or conventional care (CC), according to their preference. The two groups were compared at baseline to investigate whether there were differences between the AHC and the CC patients that may help explain their choice of care. The patients were consecutively recruited over 2(1/2) years. Sociodemographic and medical data, and the health-related quality of life (HRQL) of the two groups were compared. HRQL was assessed using a self-reporting questionnaire, including the European Organization for Research and Treatment of Cancer Core Quality of Life Questionnaire (EORTC QLQ-C30), the Impact of Event Scale (IES), five questions about social support, and two items concerning general well-being. The AHC group showed significantly poorer functioning on all the EORTC QLQ-C30 scales and an overall higher symptom burden than the CC patients. Fewer of the AHC patients were receiving cancer treatment. The AHC patients had lived longer with their cancer diagnosis, had a significantly shorter survival after study enrollment, and a significantly poorer performance status. The major differences between the two groups seemed to be related to being at different stages in their disease. The results indicate that patients are reluctant to accept home care until absolutely necessary due to severity of functioning impairments and symptom burden. These findings should be taken into consideration in planning palliative care services.

Quality of life in oral carcinoma: a 5-year prospective study.

BACKGROUND: We conducted this prospective longitudinal multicenter study to evaluate the health-related quality of life (HRQL) of patients with oral carcinoma at diagnosis, and after 1 and 5 years in relation to tumour location and treatment modality. METHODS: One hundred twenty-two patients (mean age, 61; 62% males) with oral carcinoma were evaluated with standardized HRQL questionnaires, the European Organization for Research and Treatment of Cancer Quality of Life Questionnaire Core30 (EORTC QLQ-C30) and the EORTC Head and Neck Cancer Module (EORTC QLQ-H&N35). RESULTS: Problems with teeth, dry mouth, and sticky saliva got worse between diagnosis and 5 years after diagnosis. Problems with dry mouth remained a problem between 1 and 5 years after diagnosis, except for the patients treated with surgery only. This group had fewer problems over time compared with patients receiving other treatment regimes. Survivors reported better HRQL than the nonsurvivors at diagnosis and at the 1-year follow-up. HRQL at diagnosis was associated with survival. CONCLUSIONS: HRQL at diagnosis for patients with oral carcinoma seems to be an important factor for the prognosis of both HRQL over time and survival. Treatment of oral carcinoma often results in long-term side effects such as dry mouth, problems with teeth, and sticky saliva.

Feasibility of measuring acoustic streaming for improved diagnosis of rhinosinusitis.

No noninvasive methods exist currently with the capability of distinguishing between various stages of a sinus infection. We studied a method based on induced acoustic streaming in the accumulated fluid within the maxillary sinuses. The hypothesis was that acoustic streaming will not be induced at clinically acceptable intensity levels in infectious mucous fluid because of its high viscosity, whereas detected acoustic streaming is a strong indication that the sinus content is a noninfectious serous fluid. As a model, an anthropomorphic sinus phantom with bovine cortical bone to mimic the bone surrounding the maxillary sinus was constructed. Milk (1.5% fat content) was used as model fluid. From fluid and bone attenuation measurements, an ultrasound frequency of about 5 MHz was estimated to produce the highest acoustic streaming in the sinus phantom. Simulations of the acoustic streaming in a sealed cavity also showed that the width of the ultrasound beam should be about half the size of the cavity to optimize the streaming velocity. With a 4.9-MHz continuous-wave transducer operating at a spatial peak temporal average intensity (I(spta)) of 640 mW/cm(2), an acoustic streaming velocity of 0.19 cm/s was generated and detected in the sinus phantom.

Health-related quality of life in patients with pharyngeal carcinoma: a five-year follow-up.

PURPOSE: The purpose was to evaluate the health-related quality of life (HRQL) of patients with pharyngeal carcinoma at diagnosis and after 1 and 5 years in relation to tumor location and treatment modality in a prospective multicenter study. METHODS: Eighty-nine patients with pharyngeal carcinoma (mean age, 60.0 years; 76% men) were evaluated using the European Organization for Research and Treatment of Cancer Quality of Life Questionnaire-Core 30 (EORTC QLQ-C30) and the European Organization for Research and Treatment of Cancer Quality of Life Questionnaire Head and Neck Cancer Module (EORTC QLQ-H&N35). RESULTS: Problems with dry mouth and teeth became worse between diagnosis and the 5-year follow-up. Problems with thick secretions and teeth increased between 1 and 5 years. The HRQL at diagnosis was associated with survival. Patients with oropharyngeal carcinoma reported better HRQL than patients with hypopharyngeal carcinoma. CONCLUSIONS: For patients with pharyngeal carcinoma, the HRQL at diagnosis seems to be an important factor for the prognosis of both HRQL over time and survival. Treatment of pharyngeal carcinoma often results in long-term side effects such as dry mouth, problems with teeth, and thick secretions.

Quality of life and head and neck cancer: a 5 year prospective study.

OBJECTIVES: Assessment of health-related quality of life (HRQL) in head and neck cancer patients from diagnosis to 5 years after start of treatment. STUDY DESIGN: A prospective, descriptive study METHODS: three hundred fifty-seven patients from Norway and Sweden filled in HRQL questionnaires, the European Organisation for Research and Treatment of Cancer (EORTC) QLQ-C30 and the EORTC QLQ-H and N35, six times during the first year and then after 5 years. At 5 years, 167 (87%) of the 192 living patients filled in questionnaires. RESULTS: Group data: clinical significant improvements in HRQL were not found between 1 and 5 years. Problems with teeth, opening of the mouth, dryness in the mouth, and sticky saliva were persistent or worsening. Similar findings were found regardless of sex, age, stage, or site when clinical significant changes are considered. Patients who died between 1 and 5 years reported reduced HRQL on 15 of 28 scales at 1 year compared with the survivors. Individual data: 40% of patients reported improved global HRQL from diagnosis to 5 years after start of treatment. In addition, 11% had "top scores" at both assessment points. The pattern in global HRQL scores also applies for most of the other function and symptom scales. CONCLUSION: After the first year after treatment, recovery of the persisting side effects of treatment cannot be expected for the group as a whole. Patients must be prepared for this. Some individual patients experience improvement in global HRQL. HRQL assessments in daily clinical practice can identify patients who are in need of additional support and symptom relief.

Place of death: hospital-based advanced home care versus conventional care. A prospective study in palliative cancer care.

The purpose of this prospective nonrandomized study was to evaluate time spent at home, place of death and differences in sociodemographic and medical characteristics of patients, with cancer in palliative stage, receiving either hospital-based advanced home care (AHC), including 24-hour service by a multidisciplinary palliative care team or conventional hospital care (CC). Recruitment to the AHC group and to the study was a two-step procedure. The patients were assigned to either hospital-based AHC or CC according to their preferences. Following this, the patients were asked to participate in the study. Patients were eligible for the study if they had malignant disease, were older than 18 years and had a survival expectancy of 2-12 months. A total of 297 patients entered the study and 280 died during the study period of two and a half years, 117 in the AHC group and 163 in the CC group. Significantly more patients died at home in the AHC group (45%) compared with the CC group (10%). Preference for and referral to hospital-based AHC were not related to sociodemographic or medical characteristics. However, death at home was associated with living together with someone. Advanced hospital-based home care targeting seriously ill cancer patients with a wish to remain at home enable a substantial number of patients to die in the place they desire.

Health-related quality of life (HRQOL) in family members of cancer victims: results from a longitudinal intervention study in Norway and Sweden.

This study compared the health-related quality of life (HRQOL) of family members of patients who participated in a program of palliative care (intervention family members) with those in conventional care (control family members). The HRQOL was measured by the short-form (SF-36) health survey questionnaire, including eight subscales. The longitudinal intervention study includes two sites: Trondheim, Norway and Malmø, Sweden. Our first hypothesis was that the HRQOL of the family members would deteriorate over time in the terminal phase and reach a low point a few months after the death of the patients, and thereafter gradually increase. This hypothesis was fully supported by the trajectories for the five scales, role limitation due to physical problems, vitality, social functioning, role limitation due to emotional problems, and mental health; but only partially so for the remaining three scales, physical functioning, bodily pain, and general health perception. From a second hypothesis, we expected the trajectories of the HRQOL scale scores for the two groups to show an increasing difference over time in quality of life in favor of the intervention group. This was the case for two of the scales: role limitation due to emotional problems and mental health. Before we may reach a definitive conclusion on the effects of palliative care programs for the HRQOL of family members, we need further longitudinal intervention studies with large samples.

Health-related quality of life five years after diagnosis of laryngeal carcinoma.

PURPOSE: To evaluate the health-related quality of life (HRQL) of patients with laryngeal carcinoma in a prospective longitudinal multicenter study at diagnosis, after 1 and 5 years in relation to tumor location and treatment modality. SUBJECTS AND METHODS: Eighty-six patients (mean age 66 years; 84% males) with laryngeal carcinoma were evaluated with standardized HRQL questionnaires: the European Organization for Research and Treatment of Cancer, Quality of Life Questionnaire Core-30 (EORTC QLQ-C30), the EORTC QLQ-Head and Neck Cancer Module (EORTC QLQ-H&N35), and the Hospital Anxiety and Depression Scale (HADS). RESULTS: Some significant changes in HRQL were found between diagnosis and 5 years after diagnosis, depending on the treatment given. The patients' ability to speak improved whereas some general functions deteriorated and treatment-related side effects increased. When comparing HRQL at 1 and 5 years after diagnosis, it appears that most values at the 1-year follow-up assessment persist until 5 years, but a few deteriorate. The HRQL at diagnosis seems to be associated with survival rate after 5 years, and the global quality of life scale at diagnosis tends to predict HRQL after 5 years. CONCLUSIONS: The use of HRQL questionnaires is valuable when comparing different treatments and as an aid in predicting treatment side effects. Evaluation of HRQL at diagnosis for patients with laryngeal carcinoma seems to be of value for the prognosis of HRQL over time and for the prognosis of survival.

Prospective, Longitudinal Quality-of-Life Study of Patients With Head and Neck Cancer: A Feasibility Study Including the EORTC QLQ-C30.

Despite modern advances in the treatment of head and neck cancer, the survival rate fails to improve. Considering the different treatment modalities involved, quality of life has been thought of as an additional end point criterion for use in clinical trials. A Nordic protocol to measure the quality of life of head and neck cancer patients before, during, and after treatment was established. Before the study, a pilot study was done with this protocol. The main purpose of this pilot study was to find out whether this cancer population would answer quality-pf-life questionnaires repeatedly (six times) over a 1-year period and whether the chosen questionnaires-a core questionnaire (European Organisation for Research and Treatment of Cancer Core Quality of Life Questionnaire (EORTC QLQ-C30)), a tumor-specific questionnaire, and a psychological distress measure (Hospital Anxiety and Depression scale (HAD))-were sensitive for changes to functions and symptoms during the study year. The results presented in this article all refer to the pilot study. Forty-eight consecutive patients agreed to participate in the study. The most common tumor locations were the oral cavity (17) and the larynx (12). Almost all patients received combined treatment: 45 of 48 radiation therapy, 18 of 48 chemotherapy, and 17 of 48 surgery. After the primary treatment, 40 patients had complete tumor remission. Four of the 48 patients did not answer any questionnaires and were therefore excluded from the study. Of the remaining 44 patients, 3 died during the study year, and another 6 withdrew for various reasons. Thirty-five (85%) of the 41 patients alive at the 1-year follow-up answered all six questionnaires and thus completed the study. Mailed questionnaires were used throughout the study. All questionnaires were well accepted and found to be sensitive to changes during the study year. The greatest variability was found for symptoms and functions related specifically to head and neck cancer. The symptoms were swallowing difficulties, hoarse voice, sore mouth, dry mouth, and problems with taste. They all showed the same pattern, with an increase of symptoms during and just after finishing the treatment. The HAD scale revealed a high level of psychological distress, with 21% probable cases of psychiatric morbidity at diagnosis. In conclusion, it was shown that the study design and questionnaires were feasible for the forthcoming prospective quality-of-life assessment of Swedish and Norwegian head and neck cancer patients.
