Head-up tilt test in complicated neurocardiogenic syncope in children.

To confirm the usefulness of head-up tilt test (HUT) in neurocardiogenic syncope (NCS) with complicating clinical features, retrospective analysis were done on 12 selected children. The age at onset was 12.7 +/- 1.9 (mean +/- SD) years. Associated clinical features were postoperative congenital heart disease (PO CHD) in 3, coexistent arrhythmia in 8 (persistent ventricular arrhythmia during exercise in 3, premature ventricular contractions in 2, ventricular couplets in 1, sinoatrial exit block in 1 and resting sinus bradycardia in 1) and ST segment depression during exercise in 1. Four of them had a history of exercise-related syncope. All 3 patients with PO CHD had arrhythmia (ventricular tachycardia in 1, sinus bradycardia in 1 and atrioventricular block in 1). HUT provoked NCS in 8 (2 during baseline tilt, 6 during isoproterenol infusion). In one each, ventricular tachycardia and loss of consciousness without hypotension and bradycardia were induced. Atenolol was tried in 5 with improvement of NCS in 4 and aggravation of dizziness in 1. During follow-up, 7 became asymptomatic (2 with atenolol) and 5 were stationary. In conclusion, HUT was valuable in diagnosing NCS even in children with complicating clinical features such as arrhythmias or PO CHD. HUT could be done as apart of initial diagnostic tests if the past history suggests NCS, regardless of associated clinical features. In some cases, the unexpected results of the test turned out useful in managing children with syncope or dizziness.     

An analysis of referral patterns for dizziness in the primary care setting.

BACKGROUND: The majority of balance disorders are non life-threatening and symptoms will resolve spontaneously. However, some patients require further investigation and many disorders may benefit from specialist treatment it is unclear whether appropriate identification and referral of this group of patients presently occurs. AIM: To review the management of patients with symptoms of dizziness within primary care. METHOD: A retrospective review of the management of 503 patients who visited their general practitioner (GP) complaining of dizziness between August 1993 and July 1995. Management was then compared with local criteria. RESULTS: On average, 2.2% of patients per year at the practices studied consulted their GP about dizziness, amounting to 0.7% of all consultations. The most common GP diagnosis was of an ear, nose, and throat (ENT) disorder (33.8%). Similarly, many of the 16% referred were directed to ENT (36%) specialists. The proportion of patients referred was significantly higher in those seeing their GP at least twice, those with symptoms lasting a year or more, or where there were additional symptoms associated with the dizziness, indicative of a cardiac, ENT, or neurological disorder. Compared with the local criteria, 17% of management decisions were deemed inappropriate. The major failing was not referring appropriate patients. This group comprised patients with chronic, non-urgent symptoms, and were significantly older than those appropriately referred. CONCLUSION: Patients with chronic symptoms of dizziness, particularly the elderly, are under-referred for specialist consultation and, therefore, do not have access to appropriate treatment regimes. This suggests a need for further training of GPs and evaluation of therapeutic needs of elderly dizzy patients.     

Wertigkeit der EKG-Telefon-Telemetrie in der Erfassung symptomatischer Herzrhythmus-Störungen

Summary The ECG-telephone-transmission (TTM) was used to record an ECG-strip during a typical symptomatic period in patients complaining of symptoms possibly caused by arrhythmias (palpitations, dizziness, paroxysm tachycardia, pulse irregularities; angina and dyspnea only if other reasons could be excluded). Patients complaining of syncope only were not admitted, because of the inability to make a telephon call successfully during such a symptomatic period. The ECG was transmitted to the CCU using a frequency modulation technique. In 60% of 196 patients an ECG-TTM could be achieved during a typical symptomatic period, whereas arrhythmias as cause for the symptoms could be excluded in 51 patients (26%). The remaining 66 patients (34%) demonstrated various arrhythmias ranging from simple SVPB and PVC to total AV-block and sustained VT.TTM, an easy-to-perform and cost-effective method allowed a successful ECG registration during a symptomatic period in almost two-thirds of symptomatic patients. In these patients arrhythmias could be verified or excluded as cause of the symptoms.

动态心电图与直立倾斜试验对不明原因晕厥的诊断价值探讨

目的探讨动态心电图(DCG)与直立倾斜试验(TTT)对不明原因晕厥的诊断价值。方法所有患者均常规进行查体、DCG、心脏超声、脑血流图、脑电图等检查,排除癫痫、短暂脑缺血发作(TIA)等疾患,考虑为血管迷走性晕厥(VVS)者,则进行TTT试验。(1)动态心电图检查:每例患者记录24h,监测导联为CM1,CM3和CM5,应用回放式计算机分析系统,分析和判断患者的心律失常与晕厥的关系,(2)直立倾斜试验检查:让患者倾斜站立于60°～90°的倾斜板上15min,每分钟测血压,并连续心电监护,观察血压、心率的变化。如诱发出晕厥或类似平时晕厥发作症状则停止试验。对未诱发出症状者,则让患者再平卧5～10min进行倾斜加异丙肾上腺素试验。结果294例不明原因晕厥患者中,经DCG检出心源性晕厥91例(31.0%),TTT检出VVS149例(50.6%),仍不能查明晕厥原因54例(18.4%)。结论DCG是诊断心律失常引起的心源性晕厥最有效的手段之一,阴性时也不能排除心源性晕厥;DCG对未发作VVS者几乎无价值,而TTT对VVS的诊断却具有重要的临床价值。     

Autonomic Dysfunction Presenting as Postural Orthostatic Tachycardia Syndrome in Patients with Multiple Sclerosis

Background: Autonomic dysfunction is common in patients suffering from multiple sclerosis (MS) and orthostatic dizziness occurs in almost 50% of these patients. However, there have been no reports on postural orthostatic tachycardia syndrome (POTS) in patients suffering from MS.Methods: The patients were included for analysis in this study if they had POTS with either a prior history of MS or having developed MS while being followed for POTS. Postural orthostatic tachycardia (POTS) is defined as symptoms of orthostatic intolerance(>6months) accompanied by a heart rate increase of at least 30 beats/min (or a rate that exceeds 120 beats/min) that occurs in the first 10 minutes of upright posture or head up tilt test (HUTT) occurring in the absence of other chronic debilitating disorders. We identified nine patients with POTS who were suffering from MS as well. Each of these patients had been referred from various other centers for second opinions.Results: The mean age at the time of diagnosis of POTS was 49±9 years and eight of the 9 patients were women. Five patients (55%) had hyperlipidemia, 3 (33%) migraine and 2 (22%) patients had coronary artery disease and diabetes each. Fatigue and palpitations (on assuming upright posture) were the most common finding in our patients (9/9). All patients also had orthostatic dizziness. Syncope was seen in 5/9(55%) of patients. Four patients (44%), who did not have clear syncope, were having episodes of near syncope. The presence of POTS in our study population resulted in substantial limitation of daily activities. Following recognition and treatment of POTS, 6/9(66%), patients were able to resume daily activities of living. Their symptoms (especially fatigue and orthostatic intolerance) improved. The frequency and severity of syncope also improved. Three (33%) patients failed to show a good response to treatment.Conclusion: Patients suffering from MS may manifest autonomic dysfunction by developing POTS. Early recognition and proper management may help improve the symptoms of POTS.     

Resumption of driving after life-threatening ventricular tachyarrhythmia

BACKGROUND: Although the privilege of driving must be respected, it may be necessary to restrict driving when it poses a threat to others. The risks associated with allowing patients with life-threatening ventricular tachyarrhythmias to drive have not been quantified. METHODS: The Antiarrhythmics versus Implantable Defibrillators (AVID) trial compared antiarrhythmic-drug therapy with the implantation of defibrillators in patients resuscitated from near-fatal ventricular arrhythmias. In the current study, we sent patients who participated in the AVID trial a questionnaire, to be completed anonymously, requesting information about driving habits and experiences. RESULTS: The questionnaire was returned by 758 of 909 patients (83 percent). Of these, 627 patients drove during the year before their index episode of ventricular tachyarrhythmia. A total of 57 percent of these patients resumed driving within 3 months after randomization in the AVID trial, 78 percent within 6 months, and 88 percent within 12 months. While driving, 2 percent had a syncopal episode, 11 percent had dizziness or palpitations that necessitated stopping the vehicle, 22 percent had dizziness or palpitations that did not necessitate stopping the vehicle, and 8 percent of the 295 patients with an implantable cardioverter-defibrillator received a shock. Fifty patients reported having at least 1 accident, for a total of 55 accidents during 1619 patient-years of follow-up after the resumption of driving (3.4 percent per patient-year). Only 11 percent of these accidents were preceded by symptoms of possible arrhythmia (0.4 percent per patient-year). CONCLUSIONS: Most patients with ventricular tachyarrhythmias resume driving early. Although it is common for them to have symptoms of possible arrhythmia while driving, accidents are uncommon and occur with a frequency that is lower than the annual accident rate of 7.1 percent in the general driving population of the United States.     

Psychological and perceptual factors associated with arrhythmias and benign palpitations

OBJECTIVE: Little is known about how patients who seek medical help for benign palpitations can be distinguished from those with clinically significant arrhythmias. This study tested whether patients with arrhythmia can be distinguished from those who are aware of sinus rhythm or extrasystoles on the basis of sex, prevalence of anxiety disorders, and heartbeat perception. METHODS: A consecutive sample of patients referred to a cardiology clinic participated in the study. Patients were diagnosed as having either arrhythmia (N = 62), extrasystoles (N = 75), or awareness of sinus rhythm (N = 47). They were assessed with use of the anxiety disorders and hypochondriasis modules of the Structured Clinical Interview for DSM-IV. Both patients and control subjects (N = 35) answered questionnaires measuring anxiety, fear of bodily sensations, and depression and underwent a heartbeat perception test. The present report focuses on patients who had palpitations but no comorbid cardiovascular disease. RESULTS: Patients with awareness of sinus rhythm could be distinguished from those with arrhythmia by several variables: female sex, higher prevalence of panic disorder, poor performance on the heartbeat perception test, report of palpitations when doing the test, higher heart rates, lower levels of physical activity, and (as trends) a greater prevalence of panic attacks, fear of bodily sensations, and depression. In contrast, patients with arrhythmias rarely reported palpitations when doing the test but were more likely to perceive their heartbeats accurately than patients with sinus rhythm and control subjects. Performance on the heartbeat perception test was intermediate in patients with extrasystoles; these patients also had an intermediate prevalence of panic disorder and intermediate depression scores. CONCLUSIONS: Measures of panic disorder and a simple heartbeat perception test could complement medical assessment in the diagnosis of patients who seek medical help for palpitations. The results also have implications for the treatment of patients with benign palpitations.     

Predicting colorectal cancer risk in patients with rectal bleeding

BACKGROUND: Rectal bleeding is an important symptom of colorectal cancer but has low predictive value in primary care. AIM: To determine which characteristics of rectal bleeding, along with other factors, are predictive of colorectal cancer. DESIGN OF STUDY: Observation study of patients with rectal bleeding referred to an open-access diagnostic clinic. SETTING: Primary care, southern England. METHOD: Symptom data were collected, using a self-completed questionnaire. Logistic regression techniques were used to determine predictors of colorectal cancer. RESULTS: There were 604 patients in the study and 22 (3.6%, 95% confidence interval [CI] = 2.0% to 5.2%) were diagnosed with colorectal cancer. Significant predictors of colorectal cancer were found to be age (<50 years: odds ratio [OR] = 1; 50-69 years: OR = 5.1, 95% CI = 1.4 to 18.6; > or = 70 years: OR = 8.2, 95% CI = 2.1 to 31.8) and blood mixed with the stool (Likelihood ratio [LR] 1.5; adjusted OR = 3.8; 95% CI = 1.4 to 10.5). Presence of haemorrhoids associated with bright red bleeding not mixed with stool reduced the likelihood of cancer (OR = 0.4, 95% CI = 0.1 to 1.2) but did not eliminate it--a cancer was present in 2% of patients with these symptoms. CONCLUSION: Patient-reported type of rectal bleeding as an isolated symptom has insufficient diagnostic value to be useful in general practice. By studying referred patients, we may even have overestimated its value. At best, it could be useful as a component of a composite symptom score to guide referral decisions.     

Psychiatric syncope: a new look at an old disease

Psychiatric disorders in patients with unexplained syncope or presyncope have received little attention in the recent medical literature. Seventy-two patients with unexplained syncope and presyncope referred to the Duke Syncope Clinic received a standardized evaluation. Symptoms appeared to be explained by a psychiatric diagnosis in 17 (24%) patients (panic disorder in 13%, and major depression in 11%). These patients were younger than other patients with syncope and presyncope (p less than .001) and had more disability due to their syncope and presyncope (p less than .01). They also had more frequent episodes of syncope (p less than .005) and more symptoms as a part of their prodrome (p less than .0001). Treatment aimed at the psychiatric diagnosis resulted in a remission from syncopal or presyncopal symptoms in 90% of patients who complied with therapy. The authors conclude that psychiatric disorders are common in patients with syncope and presyncope, that certain characteristics of the patient and prodrome may alert physicians to a psychiatric diagnosis, and that directed treatment may result in relief from symptoms.     

Acute stress modulates symptom awareness and hormonal counterregulation during insulin-induced hypoglycemia in healthy individuals

The purpose of this study was to determine whether the perception of hypoglycemia is reduced during acute stress. In Session I each of our 40 healthy male volunteers received a bolus injection of human insulin (0.05 IU/kg) resulting in plasma glucose nadirs of below 2.8 mmo/L. In Session 2 participants received insulin or saline, with half of each group being stressed by having to prepare and give a speech. Data collection at 5- to 25-min intervals included a symptom checklist, blood pressure, heart rate, and blood sampling for measurement of plasma glucose and counterregulatory hormones. Individuals in the stress + insulin group were less sure of having received insulin and ate fewer cookies compared with controls. They reported lower intensity of the hypoglycemic symptoms of palpitations, tremor, dizziness, and blurred vision, in contrast to the reduced subjective and behavioral reactions, they showed the strongest hormonal counterregulation. We conclude that acute stress during hypoglycemia reduces symptom awareness and the ability to detect hypoglycemia.     

Factors identifying higher risk rectal bleeding in general practice

BACKGROUND: Rectal bleeding is a common symptom. The ability to distinguish those patients having serious underlying pathology from those with self-limiting conditions is a continuing dilemma in general practice. AIM: To determine the factors affecting the predictive and diagnostic value of rectal bleeding for bowel cancer in primary care. DESIGN OF STUDY: One-year prospective observational study. SETTING: Three large general practices. METHOD: Three hundred and nineteen consecutive patients over the age of 34 years consulting their GPs with rectal bleeding were included in the study. Investigation was by flexible sigmoidoscopy or a questionnaire and review of all patients took place after 18 months. The main outcome measures were consultation rates; the prevalence of cancer, colitis and significant polyps in patients presenting with rectal bleeding; its diagnostic value when occurring with or without a change in bowel habit, perianal symptoms and abdominal pain. RESULTS: The consultation rate for rectal bleeding in patients over the age of 34 years was 15 per 1000 per year; 3.4% had colorectal cancer. The prevalence of cancer increased to 9.2% when the rectal bleeding was associated with a change in bowel habit, and to 11.1% when it was without perianal symptoms. Thirty-six per cent of cancer patients had a palpable rectal mass. CONCLUSION: Over 96% of the patients who present to their GPs with rectal bleeding do not have cancer. Greater awareness of the diagnostic value of the different symptom combinations of rectal bleeding could help GPs adopt different management strategies for patients at higher and very low risk of cancer.

The assessment of psychological symptoms of patients referred to community mental health teams: distress,chronicity and life interference

Mental health trusts are concerned to allocate scarce resources to those patients requiring secondary care services, rather than to those who can be managed in the community. It is important therefore to gain insight into the types of patient being referred into community mental health teams. This study was undertaken to explore this question. 421 patients completed the General Health Questionnaire and a newly devised symptom checklist, which allows assessment of distress/severity, chronicity and interference with life of individual symptoms. 81% of patients met criteria for caseness on the GHQ and those who did not still had a number of chronic symptoms. In regard to specific symptom profiles referred patients endorsed a wide variety of symptoms, related to anxiety, depression and impulse control. The most common anxiety symptom related to adjustment reactions and possibly post-traumatic stress. The most common mood symptom was mood instability, followed by fatigue and sleep problems. The majority of patients believed that they had had their symptoms and problems for longer than a year, indicating that many of the referrals to community teams are not short-term crises. Data suggests that the vast majority of referrals are appropriate but also point to a need for specific forms of intervention for the most common symptoms.

‘Shell shock’ Revisited: An Examination of the Case Records of the National Hospital in London

During the First World War the National Hospital for the Paralysed and Epileptic, in Queen Square, London, then Britain’s leading centre for neurology, took a key role in the treatment and understanding of shell shock. This paper explores the case notes of all 462 servicemen who were admitted with functional neurological disorders between 1914 and 1919. Many of these were severe or chronic cases referred to the National Hospital because of its acknowledged expertise and the resources it could call upon. Biographical data was collected together with accounts of the patient’s military experience, his symptoms, diagnostic interpretations and treatment outcomes. Analysis of the notes showed that motor syndromes (loss of function or hyperkinesias), often combined with somato-sensory loss, were common presentations. Anxiety and depression as well as vegetative symptoms such as sweating, dizziness and palpitations were also prevalent among this patient population. Conversely, psychogenic seizures were reported much less frequently than in comparable accounts from German tertiary referral centres. As the war unfolded the number of physicians who believed that shell shock was primarily an organic disorder fell as research failed to find a pathological basis for its symptoms. However, little agreement existed among the Queen Square doctors about the fundamental nature of the disorder and it was increasingly categorised as functional disorder or hysteria.     

Comparison of allergic rhinitis and vasomotor rhinitis patients on the basis of a computer questionnaire

From 1 July 1990 to 31 December 1991, all patients referred to the Allergy Section of the ENT Department, University Hospital, Lund, Sweden, ( n =678) answered a 134-item questionnaire presented on the screen of a personal computer by pressing Y (for yes) or N (for no) on the keyboard. The objective of this study was to compare the questionnaire responses from patients with allergic rhinitis (AR) with those of patients with perennial nonallergic rhinitis or vasomotor rhinitis (VMR). Nasal blockage was the predominant symptom in the VMR group, whereas the AR patients mainly suffered from eye irritation, sneezing, and, to some extent, rhinorrhea. Concomitant asthma was more prevalent in the AR group than in the VMR group, whose histories were characterized by symptoms associated with airway infections. About 60% of both groups reported problems with such nonspecific airway irritants as cigarette smoke and perfumes. With respect to the diagnostic reliability of the history, in the AR group the order of accuracy (according to the skin prick test results) of reported hypersensitivity to allergens was as follows: cat > timothy > birch > dust mite > mugwort. A history of hypersensitivity to molds as a cause of symptoms was of no diagnostic value. The findings suggest that there are several differences in the medical histories of AR and VMR patients that merit further investigation.     

Prevalence of irritable bowel syndrome: a community survey.

BACKGROUND: Irritable bowel syndrome (IBS) is a common health problem affecting a substantial proportion of the population. Many individuals with symptoms of IBS do not seek medical attention or have stopped consulting because of disillusionment with current treatment options. Such patients may choose to re-consult with the advent of new therapies with a resulting impact on health services. AIM: To generate reliable estimates of the prevalence of IBS by age, sex and symptom group. DESIGN OF STUDY: Postal survey. SETTING: Patients selected from registers of eight general practices in north and west Birmingham. METHOD: Eight thousand six hundred and forty-six patients aged >or=18 years were randomly selected from practice lists. Selected patients received a questionnaire, which included diagnostic criteria for IBS. A second questionnaire, seeking more detailed information, was sent to those whose responses indicated the presence of IBS symptoms. RESULTS: Of the 8386 patients surveyed 4807 (57.3%) useable replies were received. The community-based prevalence of IBS was 10.5% (6.6% of men and 14.0% of women). Overall the symptom profiles were characterised by diarrhoea (25.4%), constipation (24.1%) and alternating symptoms (46.7%). Over half (56%) of all patients had consulted their general practitioner within the past 6 months and 16% had seen a hospital specialist. A quarter of patients consulted more than twice and 16% were referred to secondary care; almost half were on prescribed medication. However, the majority of patients were self-treated. Less than half of those currently reporting symptoms of IBS according to the Rome II criteria had received a diagnosis of IBS. Reduced quality of life and a previous diagnosis of a stomach ulcer were identified as predictors of consultation. CONCLUSION: Quality of life was significantly reduced in patients with IBS. There is a substantial burden on primary healthcare services despite over half of those with symptoms also self- medicating. The Rome II diagnostic criteria identified those most affected by their symptoms and are a valid clinical tool. Population-based health surveys will need to supplement the Rome criteria with questions aiming to identify patients formally diagnosed but whose symptoms are currently under control if prevalence is to be reliably estimated.     

Observation and provocation in diagnostics of syncope

Despite a large number of modern examination techniques, possibilities for differential diagnostics of syncope remain limited even at the beginning of the 21st century. Up to 35% of patients get discharged from hospitals without knowing the exact nature of loss of consciousness. The main reason for this is that a syncopal attack is a symptom of a range of diseases and conditions, and a large number of examination methods may be necessary to establish its cause. One group of methods helps find the supposed morphological substrate of attacks, while other methods serve as evidence of its pathogenetic mechanism. What is their real diagnostic value? And which strategy--waiting for a spontaneous attack and observing it or provocation of syncope--is the best one when a patient with syncope is being examined? The article discusses advantages and disadvantages of diagnostic methods that are commonly used in diagnostics of reasons for loss of consciousness.
