The effect of educational intervention on intercultural communication: results of a randomised controlled trial.

BACKGROUND: Due to worldwide migration to Western countries, physicians are increasingly encountering patients with different ethnic backgrounds. Communication problems can arise as a result of differences in cultural backgrounds and poor language proficiency. AIMS: To assess the effectiveness of an educational intervention on intercultural communication aimed to decrease inequalities in care provided between Western and non-Western patients. DESIGN OF STUDY: A randomised controlled trial with randomisation at the GP level and outcome measurements at the patient level. SETTING: General practice in Rotterdam. METHOD: Thirty-eight Dutch GPs in the Rotterdam region, with at least 25% of inhabitants of non-Western origin, and 2407 visiting patients were invited to participate in the study. A total of 986 consultations were finally included. The GPs were educated about cultural differences and trained in intercultural communication. Patients received a videotaped instruction focusing on how to communicate with their GP in a direct way. The primary outcome measure was mutual understanding and the secondary outcomes were patient's satisfaction and perceived quality of care. The intervention effect was assessed for all patients together, for the 'Western' and 'non-Western' patients, and for patients with different cultural backgrounds separately. RESULTS: An intervention effect was seen 6 months after the intervention, as improvement in mutual understanding (and some improvement in perceived quality of care) in consultations with 'non-Western' patients. CONCLUSIONS: A double intervention on intercultural communication given to both physician and patient decreases the gap in quality of care between 'Western' and 'non-Western' patients.

Training, communication, and information needs of mental health counselors in the United Kingdom.

OBJECTIVE: This national cross-sectional survey investigated the communication and information needs of mental health counselors in the United Kingdom as well as the difficulty these professionals experienced in obtaining help from other mental health care providers. METHODS: Mailed questionnaires were sent to a random sample of 400 registered counselors. A total of 230 counselors returned the questionnaire, for a response rate of 58 percent. Descriptive statistics, correlations, and multiple logistic regression analysis were used to analyze the results. RESULTS: The respondents reported being in contact mostly with other counselors, general practitioners, and psychiatrists. Most of the respondents (80 percent) reported other counselors to be quite or extremely helpful when consulted; the proportions were much lower for other types of practitioners, especially general practitioners and psychiatrists. Reported barriers to coordination of counseling services included lack of time and communication problems with other professionals. A total of 160 respondents (70 percent) reported not having the necessary training or skills for managing severe cases of mental illness, and 168 (73 percent) indicated that they had a need for information about mental illness. Predictors of information needs were a lack of the necessary skills for managing severe cases, contact with mostly other counselors, and a desire for information about illness, the services of voluntary agencies (agencies with charity status and other nonstatutory organizations), and mental health law. CONCLUSIONS: This survey highlighted the importance of meeting the information, communication, and training needs of mental health counselors in the United Kingdom in order for counselors to provide high-quality counseling services.

Telemedicine: Strabismus e-consultation.

BACKGROUND: Volunteer ophthalmologists can achieve success with teaching and service programs working with high intensity over a short term. Continuation of initially successful programs may be limited by lack of timely, effective communication and follow-up. In an attempt to overcome these limitations, a total of 6 telemedicine programs were established after a successful trial program at the Ramon Pando Ferrer Hospital in Havana, Cuba. METHODS: Two pediatric ophthalmology-strabismus clinics, one in Cuba and one in Romania, were provided a digital camera and a computer in order to obtain and then transmit by e-mail patient images obtained according to a prescribed format. Ophthalmologists in both of these programs were instructed personally during an orientation period in their clinics. Training included use of a digital camera and computer, patient examination, and surgical technique in the operating room. Four additional programs referred patients via digital images after receiving only written and oral instruction. RESULTS: The diagnosis and treatment plan determined by one of us (E.M.H.) for each of the first 15 Cuban patients after study of digital images sent by e-mail was the same as the diagnosis and treatment plan determined by the same observer after in-person examination of the patients. On the basis of the level of confidence attained in these patients, 35 additional patients from a total of 6 clinics were seen by digital consultation only. CONCLUSION: A store-and-forward telemedicine consultation technique that uses digital images and e-mail holds promise to be an effective means for carrying out consultation for patients with strabismus.

An application of autocorrelation methods to the interpretation of intestinal motility records.

The application of statistical communication techniques to the analysis of intestinal motility records has made available certain information that has heretofore been obscure. This information is: 1. A measure of total activity expressed in square millimeters of Hg. 2. The frequency and amplitude of segmental activity. 3. A measure of the random variations in the amplitude of the "segmental" waves. 4. A measure of random activity and the range and relative amplitudes of the frequencies making up this component.

The complementary role of computerized axial transmission tomography and radionuclide imaging of the brain.

Computerized axial transmission tomography and radionuclide imaging are complementary procedures, and the following recommendations are made as to their use. Where there is no real clinical suspicion of intracranial disease, either modality can be used for "rule out" screening; the choice can frequently be made on the basis of which modality is cheaper or more quickly available. It should be remembered that "quicker" is often "cheaper". Total cost is determined, not only by the cost of the procedure, but also the per diem costs incurred in waiting for that procedure. Thus the more expensive modality may, in effect, be cheaper if delays are shorter. Screening of the elderly patient, particularly when atrophy or communicating hydrocephalus is of clinical concern, should be by the CT method because of its ability to visualize cerebrospinal fluid spaces. When clinical signs and symptoms point to intracranial abnormality, both modalities should be utilized. If either study done first is normal, use of the other modality is mandatory. When the first study is positive with pathognomonic findings for a specific disease, which totally explains the patient's neurologic problems, the second study need not be employed. Such examples might include the fresh cerebral hemorrhage demonstrated by CT imaging, the AV malformation defined by dynamic-static radionuclide imaging, or multifocal metastatic lesions defined by either. However, when the clinical picture is not totally and satisfactorily explained by the demonstrated disease, the other modality should also be employed. Under many circumstances, neither study will be so reliable, specific, and free of false-negative or false-positive findings as to warrant ignoring the additional information potentially available from the other study.

Parent and physician attitudes regarding electronic communication in pediatric practices.

OBJECTIVE: To determine 1) the electronic mail (e-mail) capabilities of families, general pediatricians (GPs), and subspecialty pediatricians (SPs) from an integrated pediatric health care delivery system and 2) the knowledge base and attitudes of these groups regarding the potential issues involved in using e-mail for physician-patient communication. METHODS: Parents were interviewed in the offices of participating practices using a standardized survey tool. Pediatricians and staff were interviewed using a separate instrument. The data were entered into a database for analysis. RESULTS: A total of 325 parents and 37 physicians were interviewed. Fifty-seven percent of the 161 parents who were interviewed at the GP offices and 66% of the 164 families that were interviewed at SP offices had access to e-mail. Parents aged 31 to 40 years were significantly more likely to have access to e-mail than parents of other age groups. Access to e-mail increased with family income and parental education. Most (74%) parents who were interviewed expressed interest in using e-mail to contact their child's physician/physician's office for several purposes, including getting information or test results, scheduling appointments, and/or discussing a particular symptom. Although both groups of parents expressed concerns about confidentiality, parents at the GP offices were significantly more concerned (median(GP) = 95 vs median(SP) = 70). Seventy-four percent of GPs and 100% of SPs had access to e-mail; however, 79% did not want to use e-mail for physician-patient communication, citing concerns about confidentiality and the time demands that patient e-mail might engender. CONCLUSIONS: The majority of parents and pediatricians at both general and subspecialty pediatric offices are capable of communicating electronically. Parents and pediatricians are aware of the issues surrounding e-mail use for patient communication. Most parents express an interest in using e-mail for patient-physician communications, whereas most physicians are opposed to this practice.

Bronchofiberscopy in asthmatics: a method for minimizing risk of complications.

Reasoning from known effects of salbutamol on the bronchial smooth muscle cell and their enhancement in asthmatics through steroids, this communication proposes a method employing these substances in such a way as to prevent bronchospasm during fiberoptic bronchoscopy. Following split-dosage administration of 100 mg prednisolone prior to bronchoscopy, a total of 3.75 mg salbutamol in a diluted saline solution is instilled intrabronchially through the biopsy channel. Transnasal fiberoptic bronchoscopy incorporation this method was performed in 15 asthmatics with neither laryngospasm nor bronchospasm being observed. In fact, comparison of FEV1 and FVC rates before and after bronchofiberscopy showed increases of 17% (t = 6.5513, p less than 0.0005) and 12% (t = 5.2718, p less than 0.0005), respectively. In a control group of 17 chronic bronchitics showing an improvement of 15% in flow rates after bronchodilators, no significant change was seen in FEV1 and FVC following fiberbronchoscopy. This procedure not only renders the diagnostic bronchofiberscopy relatively safe in asthmatics, but may be of use within the context of intensive care in serious bronchospasm refractive to conventional therapy.

An auditory brain-computer interface based on the self-regulation of slow cortical potentials.

OBJECTIVES: Communication support for severely paralyzed patients with visual impairment is needed. Therefore, the feasibility of a brain-computer interface (BCI) using auditory stimuli alone, based on the self-regulation of slow cortical potentials (SCPs), was investigated. METHODS: Auditory stimuli were used for task and feedback presentation in an SCP self-regulation paradigm. Voluntarily produced SCP responses and measures of communication performance were compared between 3 groups (total of N = 59) of visual, auditory, and cross-modal visual-auditory modality. Electroencephalogram recordings and training from Cz-mastoids were carried out on 3 consecutive sessions. Data of 1500 trials per subject were collected. RESULTS: Best performance was achieved for the visual, followed by the auditory condition. The performance deficit of the auditory condition was partly due to decreased self-produced positivity. Larger SCP response variability also accounted for lower performance of the auditory condition. Cross-modally presented stimuli did not lead to significant learning and control of SCP. CONCLUSIONS: Brain-computer communication using auditory stimuli only is possible. Smaller cortical positivity achieved in the auditory condition, as compared to the visual condition, may be a consequence of increased selective attention to simultaneously presented auditory stimuli. To optimize performance, auditory stimuli characteristics may have to be adapted. Other suggestions for enhancement of communication performance with auditory stimuli are discussed.

[Incidence and severity of coronary artery disease in patients with acute aortic dissection: comparison with abdominal aortic aneurysm and arteriosclerosis obliterans].

OBJECTIVES: The incidence and severity of coronary artery disease were studied in patients with acute aortic dissection (AAD), and compared with coronary artery disease in patients with abdominal aortic aneurysm (AAA) or arteriosclerosis obliterans (ASO). METHODS: A total of 71 patients(42 males, 29 females, mean age 61.4 +/- 10.0 years) with AAD, undergoing coronary angiography between 1988 and 1999, were studied including 38 patients with open communication type and 33 patients with thrombosed type. According to the Stanford classification, 18 patients were type A and 53 patients were type B. Patients with AAD following Marfan syndrome or chest trauma were excluded from the study. Selective coronary angiography was performed in age- and sex-matched patients with AAA(n = 57; 42 males, 15 females, mean age 63.9 +/- 4.6 years) or ASO (n = 95; 66 males, 29 females, mean age 62.4 +/- 9.4 years). Coronary artery disease was defined as > or = 75% stenosis (left main trunk lesion of > or = 50% stenosis) by multidirectional imaging. RESULTS: Significant coronary artery disease was demonstrated in 14 patients with AAD (19.7%), 25 patients with AAA (43.9%), and 49 patients with ASO (51.5%). The incidence of coronary artery disease was significantly lower in the AAD group than in the other two groups (p < 0.05). One-vessel disease was present in approximately 70% of the patients with AAD and coronary artery disease. In contrast, multivessel disease was observed in approximately 50% of patients with AAA and ASO. Classification of the patients with AAD according to the blood flow in the false lumen showed coronary artery disease was more highly associated with the thrombosed type [10 (30.3%) of 33 patients] than the open communication type [4 (10.5%) of 38 patients]. Multivariate logistic regression analysis of the patients with AAD showed coronary artery disease was associated with a high serum total cholesterol level (p = 0.025) and the thrombosed type (p = 0.043). CONCLUSIONS: The incidence of coronary artery disease was significantly lower among patients with AAD than among age- and sex-matched patients with AAA or ASO. Coronary artery disease developed in 30% of the patients with the thrombosed type of AAD, although the prognosis seemed to be good.

Use of a risk communication model to evaluate dietetics professionals' viewpoints on genetically engineered foods and crops.

The complex issues surrounding the application of genetic engineering to food and agriculture have generated a contentious debate among diverse interest groups. One pervasive dimension in the resultant discourse is the varying perceptions of the risks and benefits of genetically engineered foods and crops. In the risk communication model, technical information is evaluated within the context of an individual's values and perceptions. The purpose of this study was to explore how dietetics professionals respond to a complex set of interrelated issues associated with genetically engineered foods and crops and to identify what varying viewpoints may exist. Participants were asked to sort a total of 48 statements distributed across eight issue areas according to level of agreement and disagreement. Using Q methodology, a total of 256 sortings were analyzed using the centroid method and varimax rotation in factor analysis. Three distinct viewpoints emerged: Precautionary (R(2)=43%), Discerning Supporter (R(2)=11%), and Promoting (R(2)=5%). Across all viewpoints, respondents agreed that dietetics professionals should employ critical thinking skills to communicate the social, economic, environmental, ethical, and technical aspects of genetically engineered foods and crops. The findings have implications for how dietetics professionals can foster an open interchange of information among diverse groups.

Voice rehabilitation in laryngectomees: comparison of daily-life performance of 4 types of alaryngeal speech.

BACKGROUND: We compared 4 kinds of alaryngeal speech available in Taiwan in the performance of daily-life tasks. The speech methods included pneumatic device (Taiwan tube), electrolaryngeal speech, esophageal speech, and tracheoesophageal prosthesis. METHODS: Questionnaires covering various communication situations in daily-life tasks as well as subjective feelings about using alaryngeal speech were distributed to members of The Taiwan Laryngectomees' Association and were collected mostly in April 2000 in their annual meeting. RESULTS: A total of 108 members responded to the questionnaire (totally 160 were questionnaires distributed). The mean age of respondents was 68.6 years, and the average time after surgery was 14.5 years. A pneumatic device was used by 58.8% of the responders, esophageal speech was used by 24.7%, an electrolarynx by 10.3%, and a tracheoesophageal prosthesis by 6.2%. No statistical difference was noted among patients using any of the 4 devices in terms of 13 communication tasks in daily life, except 4 questions such as the convenience of alaryngeal speech, embarrassment in face of strangers, the effort required to speak, and the discomfort in throat/neck/mouth when speaking. No statistical differences were noted among the 4 devices in terms of intelligibility. CONCLUSIONS: All 4 alaryngeal speech methods can serve most of the communication functions in daily life tasks with no differences in intelligibility. Limitations in loudness and tone were common problems. It is crucial for surgeons to understand the performance of various alaryngeal speeches in daily life during rehabilitation consultations with patients.

Effect of diabetes drug counseling by pharmacist, diabetic disease booklet and special medication containers on glycemic control of type 2 diabetes mellitus: a randomized controlled trial.

BACKGROUND: type 2 diabetes mellitus continues to increase in prevalence worldwide. Many factors have been cited as contributing to compliance, such as family and social support, education, number of tablets per dose, frequency of administration and health care provider communication. Toward these goals, the present study was developed to measure the effect offactors on glycemic control such as diabetes education by pharmacists, a diabetes disease booklet and special medication containers. MATERIAL AND METHOD: A total of 360 volunteers with type 2 DM patients were recruited, participants were simple randomized to control 180 and intervention 180 patients. Which intervention categorized to 4 groups; all intervention groups received diabetes drug counseling by a pharmacist, one group received plus a diabetes booklet, one received plus special medical containers and the last group received all of them. The interventions were done at the 1st time of visit. Both the control and intervention groups were monitored for fasting plasma glucose and HbA1c at 0, 3, 6 months and glycemic level in both groups was compared. RESULTS: After 3 months, mean fasting plasma glucose and HbA1c decreased wiih the intervention group vs. control group (152.36 +/- 39.73 to 131.52 +/- 35.22 mg%) and (150.16 +/- 41.78 to 153.98 +/- 47.95 mg%) respectively; (p < 0.001). HbA1c level 8.16 +/- 1.44 to 7.72 +/- 1.26 vs 8.01 +/- 1.51 to 8.38 +/- 1.46 respectively; (p < 0.001). After 6 months, mean fasting plasma glucose and HbA1c decreased with the intervention group vs. control group (152.36 +/- 39.73 to 145.20 +/- 46.07 mg%) and (150.16 +/- 41.78 to 159.16 +/- 54.90 mg%) respectively; (p < 0.013). HbA1c level 8.16 +/- 1.44 to 7.91 +/- 1.27 vs. 8.01 +/- 1.51 to 8.80 +/- 1.36 respectively; (p < 0.001). The most favorable glycemic outcome was the group that received all of the interventions; mean FPG was reduced from 147.46 +/- 36.07 to 125.38 +/- 31.12 mg% (p < 0.000) in 1nd visit (3 months later) and still reducing effect on the 2nd visit (6 month later) mean FPG from 147.46 +/- 36.07 to 130.21 +/- 33.96 mg% (p < 0.016) also the same way in HbA 1c level. The group that received only drug counseling by pharmacist had no significant reduction in FPG and HbA1c. (p > 0.05). CONCLUSION: Drug counseling by a pharmacist has little beneficial effect on diabetes management outcome compared to the diabetes booklet and special drug container. To improve glycemic control of type 2 DM is to integrate self-management in daily life, wide a variety of education, drug taken behavior and health care provider available communication produce improvement in patient management and is somewhat better when used in combination.

Comparison between subjective and objective measures of active hearing protector and communication headset attenuation.

A masked-threshold and a loudness-balance method have been developed to estimate the attenuation of communication headsets and hearing protectors with built-in active noise reduction (ANR) systems. Both methods are used to estimate the attenuation of the ANR systems and the masked-threshold method is also used to estimate the total attenuation (active plus passive) of the device. The procedures are designed to be used in the presence of environmental noise, and to minimize the noise exposure of subjects during the measurements. For comparison, physical measurements of insertion loss have also been performed using a miniature microphone in the concha. Experiments showed that the masked-threshold methods tends to give increased estimates of the attenuation if the noise reduction of the left and right earcup ANR systems differs, as commonly occurs in practice. In contrast, the loudness-balance method reduces the estimates of the active attenuation. Insertion loss measurements may be influenced by the position of the microphone, owing to the spatial variability of the sound field under an earmuff when the ANR system is operating. Differences between physical and subjective measurements of up to 20 dB have been obtained in this study at frequencies of 250 Hz and below for a device in which the sound pressure varied substantially near, and within, the ear canal.

Aorto-cavitary fistulous tract formation in infective endocarditis: clinical and echocardiographic features of 76 cases and risk factors for mortality.

AIMS: To investigate the clinical features, echocardiographic characteristics, management, and prognostic factors of mortality of aorto-cavitary fistulization (ACF) in infective endocarditis (IE). Extension of infection in aortic valve IE beyond valvular structures may result in peri-annular complications with resulting necrosis and rupture, and subsequent development of ACF. Aorto-cavitary communications create intra-cardiac shunts, which may result in further clinical deterioration and haemodynamic instability. METHODS AND RESULTS: In a retrospective multi-centre study over 4681 episodes of IE, a total of 76 patients with ACF [1.6%, confidence interval (CI) 95%: 1.2-2.0%] diagnosed by echocardiography or during surgery were identified. Fistulae were found in 1.8% of cases of native valve IE and in 3.5% of cases of prosthetic valve IE from the general population and in 0.4% of drug abusers. PVE was present in 31 (41%) cases of ACF. Transthoracic and transoesophageal echocardiography detected the fistulous tracts in 53 and 97% of cases, respectively. Peri-annular abscesses were detected in 78% of cases, fistulae originated in similar rates from the three sinuses of Valsalva, and the four cardiac chambers were equally involved in the fistulous tracts. Heart failure (HF) developed in 62% of cases and surgery was performed in 66 (87% CI 95% 77-93%) patients with a mortality of 41% (95% CI 30-53%) in the overall population. Multivariate analysis identified HF (OR 3.4, CI 95% 1.0-11.5), prosthetic IE (OR 4.6, CI 95% 1.4-15.4) and urgent or emergency surgical treatment (OR 4.3, CI 95% 1.3-16.6) as variables significantly associated with an increased risk of death. Major complications during follow-up (death, re-operation, or re-admission for HF) among the five operative survivors with residual fistulae occurred in 20 and 100% of patients at 1 and 2 years, respectively. CONCLUSION: Aorto-cavitary fistulous tract formation is an uncommon but extremely serious complication of IE. In-hospital mortality was exceptionally high despite aggressive management with surgical intervention in the majority of patients. Prosthetic IE, urgent surgery, and the development of HF identify the subgroup of patients with IE and ACF that have significantly increased risk of in-hospital death.

[Studies on direct and indirect economic burden of disease and related factor in countryside of Qingdao city in 2001].

OBJECTIVE: To study the condition of economic burden of disease in the countryside and to explore the related factors. METHODS: Human capital method and two-step method were used in the calculation of economic burden of disease. RESULTS: The total economic burden of disease among 3359 persons was 3072 225 Yuan. Noncommunicable conditions were accounted for 62.95%, while communicable disease, maternal and perinatal conditions accounted for 24.25%, and injury accounted for 9.83% respectively. The direct economic burden of disease was 1,559,619 Yuan and the indirect economic burden of disease was 1,472,606 Yuan. The economic burden of disease for each person was 914 Yuan. The equal burden of disease among patients with disability and without disability were 3070 Yuan and 680 Yuan respectively (P < 0.001). There was significant difference among different age groups. The influencing factors were found to include having noncommunicable disease, age, disability and the condition of marriage. CONCLUSION: Corresponding policy to cope with conditions of different age groups needs to be developed to reduce the economic burden of disease in the countryside.

General practitioners and neurotelemedicine.

Predicting attitudes towards teleconsultation systems and intentions of use is crucial at the beginning of the implementation phase, due to the critical role of human factors in its acceptance and continuous utilisation. The main objective of this study was to assess and understand GP's attitudes and intentions towards using the teleconsultation system in Neurology, implemented in Lisbon, between Hospital de Santa Maria/Neurology Outpatient Clinic and the Health Care Centers of its Health Unit. The final aim is the promotion of a wide acceptance and utilisation of the system, through the development of adequate communication strategies. A predictive model "Theory of Reasoned Action" was chosen as method. It was operated with the application of a questionnaire to a sample of 53 GP's, developed from the results of a content analysis of 10 interviews. A total of 44 GP's stated that, probably they will use the system, 5 were neutral and 4 probably will not use it. The responses were submitted to factor and multiple regression analysis. Attitude was determined by only one factor "Accessibility and Quality" (b = 0.486; p = 0.007) from the 5 factors obtained. The intention variance was explained in 26.9% by the attitude and subjective norm. However, only the attitudinal factor (b = 0.469; p = 0.002) contributes significantly to its explanation with no significant influence from the subjective norm. GP's intentions towards using the system are very positive. Nevertheless, there are significant differences between the centers that are participating and not participating in the project. Communication strategies envisaging dissemination and generalised acceptance and utilisation should focus on accessibility and quality of care aspects.

[Cost effectiveness and patient benefit of digital image management systems for radiology].

In many countries today, politicians are faced with the difficulty of having to reduce the overproportional increase in the cost of healthcare. In this context the contribution of medical technology to costs in the total spent are nearly always overestimated and its potential for savings underestimated. Based on international studies, investment and subsequent running costs for large, high-tech systems for diagnosis and therapy will be shown to account for only about 1% of the total cost of healthcare. Impressive examples of the application of computed tomography, magnetic resonance tomography and digital angiography deliver statistics regarding valid patient benefits and efficiency of modern diagnostic imaging systems. Studies about related therapeutic possibilities of angioplasty and extra-corporal lithotripsy demonstrate the overall economic advantages of modern medical technology. Arising from the positive results due to the use of such equipment, the additional cost savings potential to be expected by networking these digital modalities with one another, as well as with other information and communications technology systems, will be analysed. The results will be assessed and compared to experience gained from routine clinical operation of such integrated systems. 72% of the total turnover of the Medical Engineering Group of Siemens AG for diagnostic imaging modalities in 1991/1992 arose from digital imaging modalities, and this percentage is expected to continue to increase. This paper will concentrate on these modern digital methods.

Migraine: an informative method of communication.

The Keypad Audience Response System can be used to obtain simultaneous information from a large number of people in an audience. Answers to specific questions are transmitted from a keypad (pressed by each participant) to a computer. The results are displayed on a screen within 20 seconds, expressed as percentages of total responses to each question and presented as bar diagrams or pie charts. At a meeting of the British Migraine Association, over 100 migraineurs learned how their attacks differed from, or resembled those of others. The speakers were able to clarify and discuss both questions and answers which confirmed previous findings about attack duration, prodromes, postdromes, effect of pregnancy, oral contraceptives and the menopause. Three new points emerged which merit further study: 1. Hormone replacement therapy aggravated migraine in 42% of women, 27% noted an improvement, and 31% observed no alteration. 2. Twenty-five percent prefer to sit up during an attack. 3. Seven percent reported prolonged attacks (3-7 days). The use of keypads at seminars or lectures is valuable in promoting enthusiastic audience participation, and the understanding of the diverse symptoms and manifestations of a condition. Although observations cannot be extrapolated to a wider population because all audiences are a selected group, new points requiring research may be highlighted.
