Clinical evidence for the long-term effectiveness of biofeedback related relaxation training is accumulating. The purpose of this report is to describe the population, self-regulation procedure, outcome criteria, and final outcome for patients who received Quieting Response (QR) training. Data from 340 patients who completed at least the first follow-up at 3 months is presented. Primary presenting symptoms were headaches, 72%; primary and secondary Raynaud's, 14%; hypertension, 4%; irritable colon, 4%; and miscellaneous, 6%. QR training integrated EMG and thermal feedback with deep breathing, progressive relaxation, and autogenic exercises presented on cassette tapes. Eight 1-hour weekly sessions were given, with emphasis on daily home exercises. Follow-up evaluations were at 3 months, 6 months, 1 year, and 2 years. Outcome was based on change in frequency, severity, and duration of symptoms; changes in medication; and secondary benefits. Quieting Response training was found to be most beneficial for patients with primary Raynaud's disease (18 of 23 patients, or 78% successful), classic migraines (9 of 13, or 69%), and common migraines (20 of 32, or 62%), followed by mixed headaches (79 of 131, or 60%), Raynaud's plus other symptoms (9 of 15, or 60%), and the irritable colon syndrome (7 of 13, or 54%). Less successful were patients with headaches plus other symptoms (16 of 37, or 43%), muscle contraction headaches (13 of 33, or 39%), secondary Raynaud's phenomenon (4 of 10, or 40%), and essential hypertension (5 of 15, or 33%). Speculations about the differing outcomes across symptom groups were made.

Long-term follow-up evidence for biofeedback treatment of headaches, Raynaud's disease, essential hypertension, and the irritable bowel syndrome was reviewed. Acknowledging the difficulties with cross-study comparisons, the following general success rate were determined: primary idiopathic Raynaud's disease--70%, or better; vascular headache--70%, or better; mixed headache--about 60%; and muscle contraction headache--50%, or less. With relatively fewer patients, successful outcomes with the irritable bowel syndrome and secondary Raynaud's phenomenon were roughly 60% and 40%, respectively. Few cases of clinically significant long-term decreases in diastolic blood pressure were demonstrated; however, the need for medication was reduced or eliminated in some patients. There were indications that biofeedback combined with psychotherapy resulted in highest success rates. No differences were found in effectiveness between biofeedback, other relaxation techniques, and biofeedback in combination with relaxation techniques--all had essentially comparable rates of success. No correlations between physiological and psychological measures of condition at follow-up were reported. Implications and interpretations of these findings are discussed.

A cross-sectional home survey on drug use, mental health, somatic illnesses and psychosocial issues was carried out with a nation-wide multi-stage probability sample of 4,292 persons aged 12-17, 18-24 and 25-64. This article aims at investigating the relationship of specific categories of somatic illnesses with a psychological component to the use of licit and illicit drugs. For the purpose of analysis the total sample was divided into three mutually exclusive groups: group A included respondents who have reported illicit drug use 1-3 or more times in their lives; group B comprised respondents who have reported the use of licit psychotropic drugs 3 or more times in their lives; group C included non-user respondents. A higher proportion of respondents of groups A and B of both sexes in all three age strata reported the presence of a specific somatic illness such as bronchial asthma, essential hypertension, peptic ulcer, irritable bowel syndrome, rheumatoid arthritis, dermatitis or eczema, in comparison to group C (non-user) respondents. This difference was greater in the adolescent group 12-17 years of age. Possible explanations of the association between somatic illness with a psychological component and drug use are discussed.

Congestive heart failure is the most common cause of mortality in patients with end-stage renal disease (ESRD). Ultrasonic tissue characterization with integrated backscatter offers a promising method for the noninvasive assessment of regional myocardial contractile performance and fibrosis. The aim of this study was to investigate the effect of hemodialysis (HD) on myocardial tissue characterization and left ventricular function in ESRD patients. We examined 26 patients with ESRD undergoing routine HD (age 63 +/- 12 years, duration of HD 9.2 +/- 3.2 years) and 30 patients with essential hypertension (HT; 60 +/- 10 years). Routine echocardiographic parameters and the cyclic variation of ultrasonic integrated backscatter of the ventricular septum (CV-IBS) were measured. Left ventricular mass index was significantly larger in patients with ESRD than in those with HT (217 +/- 56 vs 146 +/- 45 g/m(2), P < 0.05). The indices for left ventricular diastolic function (E/A, the ratio of left ventricular peak early to late diastolic filling velocity; DT, the deceleration time of the early diastolic filling) and CV-IBS had deteriorated significantly in patients with ESRD before HD compared with those with HT (E/A, 0.6 +/- 0.2 vs 0.9 +/- 0.3, P < 0.05; DT, 228 +/- 23 vs 184 +/- 19 ms, P < 0.05; CV-IBS, 9.0 +/- 1.3 vs 12.4 +/- 0.9 dB, P < 0.05), possibly reflecting interstitial fibrosis. In patients with ESRD, HD reduced calculated left ventricular mass index by 19% (before HD, 217 +/- 56 vs immediately after HD, 176 +/- 45 g/m(2), P < 0.05) and CV-IBS by 19% (9.0 +/- 1.3 vs 7.3 +/- 1.1 dB, P < 0.05), that possibly reflected improvement of interstitial edema. HD also significantly improved indices for left ventricular diastolic function (E/A, 0.6 +/- 0.2 vs 0.9 +/- 0.2, P < 0.05; DT, 228 +/- 23 vs 188 +/- 21 ms, P < 0.05). HD improves myocardial interstitial edema and left ventricular diastolic function in patients with ESRD. Noninvasive assessment of ultrasonic tissue characterization is useful in defining the pathophysiological changes of ventricular myocardium in patients with ESRD.

Altered pain appreciation and autonomic function are hallmarks of Cardiac syndrome X, Irritable bowel syndrome and Reflex sympathetic dystrophy. Both pain appreciation and autonomic function are controlled by the lateral medulla. This hypothesis proposes that lateral medullary ischaemia at a microvascular level is responsible for these syndromes and could also be linked to other conditions where autonomic dysfunction is a major feature such as late-onset asthma, type 2 diabetes and essential hypertension. Autonomic function is controlled by the nucleus tractus solitarius, which acts as the main viscero-afferent nucleus in the brain stem regulating vagal tone. It is particularly susceptible to ischaemia since it is highly metabolically active and lies in a medullary arterial watershed zone. The anatomical route of the vertebral artery through cervical vertebra makes it vulnerable to injury from whiplash with or without any genetic predisposition to atheroma formation. This could make microvascular occlusion commonplace and a plausible explanation for the above syndromes. Ischaemia rather than infarction occurs because of the excellent collateral blood supply in the brainstem. In support of this hypothesis, a new Transcranial doppler ultrasonography arterial signal has been described called small vessel knock, the ultrasound signal of small vessel occlusion. Recent evidence has shown that ultrasound targeting of this signal in the vertebral artery improves clinical symptoms in these syndromes which supports this hypothesis. Two such cases are discussed.
