The Effects of Hypnotherapy on Homosexuality

Fifteen homosexuals were treated with hypnosis. The patients were selected from a general psychiatric practice and had a long history of confirmed homosexual behaviour and showed no evidence of organic or psychotic illness. The type of hypnotic induction attempted in all cases is described. In those where a satisfactory depth of hypnotic trance was achieved a change in sexual orientation was suggested to the patient.Before therapy, each patient was assessed using the Kinsey scale. Results were evaluated in terms of the patient''s subsequent behaviour and his subjective feelings. Of the 15 patients, three showed no improvement, four showed a mild improvement and eight showed a marked improvement. There was a significant correlation between the depth of hypnosis achieved and the therapeutic outcome. Those patients who reached a deep level of hypnotic trance were most likely to show a marked improvement. There were no significant correlations with other factors such as degree of homosexuality as measured on the Kinsey scale and the patient''s marital status.Treatment of homosexuals with hypnosis may produce more satisfactory results than those obtainable by other means. The best results are likely to be achieved in patients who are good hypnotic subjects.     

Prevalence of asthma in adults in Busselton,Western Australia.

OBJECTIVE--To estimate whether the prevalence of asthma in adults increased over a nine year interval. DESIGN--Serial cross sectional studies of the population with a protocol that included both subjective and objective measurements. SETTING--Busselton, Western Australia. SUBJECTS--A random sample of 553 subjects aged 18-55 years in 1981, and of 1028 subjects aged 18-55 years in 1990. MAIN OUTCOME MEASURES--Respiratory symptoms measured by self administered questionnaire, bronchial responsiveness measured by bronchial challenge with histamine, and allergy measured by skin prick tests. RESULTS--Symptoms with increased prevalence were those with significant association with allergy in this population. Recent wheeze increased from 17.5% to 28.8% (p < 0.001) and diagnosed asthma increased from 9.0% to 16.3% (p < 0.001). The increase was greatest in subjects less than 30 years old. The prevalence of shortness of breath coming on at rest and of hay fever also increased significantly, but the prevalence of shortness of breath on exertion, chronic cough, bronchial hyperresponsiveness, current asthma (defined as recent wheeze plus bronchial hyperresponsiveness), and allergy did not increase. The severity of bronchial responsiveness did not change significantly in any symptom group. CONCLUSIONS--Young adults showed a significant increase in reporting of symptoms related to allergy but not in the prevalence of current asthma. The increase in symptoms may be due to increased awareness of asthma in this community, to changed treatment patterns, or to increased exposures to allergens.     

Increased activity of 5-lipoxygenase in polymorphonuclear leukocytes from asthmatic patients

The formation of 5-lipoxygenase products of arachidonic acid, 5-HETE and 5,12-diHETE, was determined in 100,000 X g supernatant of polymorphonuclear leukocytes from 17 healthy subjects, 17 patients with extrinsic asthma and 15 patients with intrinsic asthma. After the supernatant was incubated with 14C-arachidonic acid in the presence of calcium and indomethacin, the lipoxygenase products of arachidonic acid were separated by thin layer chromatography. The results were expressed as the percentage conversion of 14C-arachidonic acid into the product per 10(7) cells. The formation of 5,12-diHETE, but not of 5-HETE, was significantly increased in the cells from the group of patients with extrinsic asthma (4.38 +/- 0.78%, mean +/- S.E.; p less than 0.01) and intrinsic asthma (6.09 +/- 1.11%; p less than 0.01), when compared to normal subjects (1.74 +/- 0.30%). Both extrinsic and intrinsic asthmatics had significantly enhanced 5-lipoxygenase activity, which was expressed as the sum of percentage conversion of 14C-arachidonic acid into 5-HETE and 5,12-diHETE. The percentage conversion in normal subjects was 4.19 +/- 0.39%, 6.24 +/- 0.84% for 17 patients with extrinsic asthma (p less than 0.05), and 8.59 +/- 1.29% for 15 patients with intrinsic asthma (p less than 0.01). There was no significant difference between these asthmatic groups. These results indicate that 5-lipoxygenase activity is increased in patients with bronchial asthma.     

The Impact of Hypnotic Suggestions on Reaction Times in Continuous Performance Test in Adults with ADHD and Healthy Controls

Attention is one of the key factors in both hypnotic processes and patients with ADHD. In addition, the brain areas associated with hypnosis and ADHD overlap in many respects. However, the use of hypnosis in ADHD patients has still received only minor attention in research. The main purpose of the present work was to investigate whether hypnosis and hypnotic suggestions influence the performance of adult ADHD (n = 27) and control participants (n = 31) in the continuous performance test (CPT). The hypnotic susceptibility of the participants was measured by the Harvard Group Scale of Hypnotic Susceptibility (HGSHS:A) and the attentional task was a three minute long auditory version of the CPT. The CPT task was administered four times: before hypnosis (CPT1), after a hypnotic induction (CPT2), after suggestions about speed and accuracy (CPT3), and after the termination of hypnosis (CPT4). The susceptibility of the groups measured by HGSHS:A did not differ. There was a statistically significant decrease in reaction times in both ADHD and control groups between CPT2 and CPT3. The differences between CPT1 and CPT2, even though non-significant, were different in the two groups: in the ADHD group reaction times decreased whereas in the control group they increased. Both groups made very few errors in the short CPT. This study indicates that hypnotic suggestions have an effect on reaction times in the sustained attention task both in adult ADHD patients and control subjects. The theoretical and clinical implications are discussed.     

Prevalence of asthma and allergic disorders among children in united Germany: a descriptive comparison.

OBJECTIVES--To compare the prevalence of asthma and allergic disorders among children in Munich, western Germany, and Leipzig, eastern Germany, where environmental exposure, particularly air concentrations of sulphur dioxide and particulate matter, and living conditions have differed over the past 45 years. DESIGN--Prevalence surveys among school-children aged 9-11 years in Leipzig and Munich. Self completion of written questionnaire by the children''s parents and lung function measurements. SUBJECTS--1051 children in Leipzig and 5030 in Munich. SETTING--Primary schools. MAIN OUTCOME MEASURES--Reported lifetime prevalence of asthma and allergic disorders, and bronchial hyperresponsiveness assessed by cold air inhalation challenge. RESULTS--The lifetime prevalence of asthma diagnosed by a doctor was 7.3% (72) in Leipzig and 9.3% (435) in Munich; prevalence of wheezing were 20% (191) and 17% (786) respectively. The prevalence of diagnosed bronchitis was higher in Leipzig than Munich (30.9% (303) v 15.9% (739); p < 0.01). A significant drop in forced expiratory volume (> 9%) after cold air challenge was measured in 6.4% (57) of children in Leipzig and in 7.7% (345) of those in Munich. Hay fever (2.4% (24) v 8.6% (410); p < 0.01) and typical symptoms of rhinitis (16.6% (171) v 19.7% (961); p < 0.05) were reported less often in Leipzig than in Munich. CONCLUSIONS--No significant differences were seen in the lifetime prevalence of asthma, wheezing, and bronchial hyperresponsiveness between children in Leipzig and Munich. The lifetime prevalence of bronchitis was higher in Leipzig than in Munich. The lower prevalence rates of allergic disorders in Leipzig could point toward aetiological factors that are associated with Western lifestyle and living conditions.     

Hypnotic accumulation and hangover in elderly inpatients: a controlled double-blind study of temazepam and nitrazepam.

The hypnotic and residual sedative effects of the first and seventh of seven regular night-time doses of nitrazepam 5 mg, temazepam 20 mg, and placebo were studied in 58 elderly inpatients. Plasma temazepam and nitrazepam concentrations rose by about 50% and 113% respectively between the mornings of day 1 and day 7. Patients reported sleeping well more often after the first dose of either hypnotic (p less than 0.05), but there was no difference after the seventh dose. Reaction time was unchanged on the morning after the first dose but was significantly prolonged after the seventh dose of both hypnotics (p less than 0.01). The time taken to eliminate the letter E from a page of prose tended to be prolonged after the first dose of both drugs (temazepam v placebo, p less than 0.05; nitrazepam v placebo, not significant) and was further prolonged on the morning after the seventh dose of nitrazepam (nitrazepam v placebo, p less than 0.05). Thus plasma accumulation of the drug was associated with a deterioration in daytime performance. This change in performance did not correlate with age, cerebral blood flow, or plasma concentration, but patients of low intelligence tended to be more severely affected.     

Corticosteroid-sparing effect of chromoglycate sodium and nedocromil

The most appropiate management for bronchial asthma is the control of airway inflammation. Corticosteroids are the most effective anti-inflammatory drugs available, but they have a number of side effects; most of these are dose-dependent. In children, asthma control should be accomplished with low steroid doses possibly given by inhalation. In a double-bind placebo-controlled crossover study a group of children with mild to moderate asthma received NED 16 mg/day or BDP 400 mug/day. Values for FEV(1), PEF, symptoms use ofbronchodilators overlapped, whereas bronchial hyper-responsiveness assessed by histamine bronchoprovocation challenge was better with BDP than NED. In another case, one boy with high bronchial hyper-reactivity assessed by provocation test with hypertonic solution, experienced a significant improvement only after 2 weeks of therapy with Deflazacort (2 mg/Kg/day) followed by 4 months on combined treatment with NED (16 mg/day) and BDP (300 mu/day). Authors conclude that NED could have a steroidsparing effect over long-term use.     

Diminished bronchial reactivity to cold air in diabetic patients with autonomic neuropathy.

To investigate the role of neural pathways in the nonasthmatic response to eucapnic hyperventilation with below freezing air five diabetic patients with severe symptomatic autonomic neuropathy were studied. Their responses were compared with those shown by five diabetic patients without autonomic neuropathy and five non-diabetic controls. After bronchial provocation testing with cold air the diabetic patients with autonomic neuropathy did not show a significant fall in specific airways conductance (mean (SE) maximum percentage fall 2.0 (3)%), whereas conductance fell in the diabetic patients without neuropathy by 30.8 (2.0)% (p less than 0.001) and in the non-diabetic controls by 22.7 (4.6)% (p less than 0.02). In subjects who do not have asthma the bronchial response to cold air is mediated largely via neural mechanisms.     

Erythrapheresis in patients with polycythaemia secondary to hypoxic lung disease.

Erythrapheresis was performed in 10 patients with polycythaemia secondary to hypoxic lung disease (mean PaO2, 6.8 kPa (51 mm Hg)). The mean packed cell volume decreased from 0.64 to 0.48 in men and from 0.56 to 0.42 in women, with significant decreases in blood viscosity at both high and low shear rates (p less than 0.001). Patients showed significant improvement in six-minute walking distances (p less than 0.001) and in tests of mental alertness (p less than 0.01) compared to control subjects. Visual analogue scales confirmed symptomatic improvement after erythrapheresis. Erythrapheresis significantly improved symptoms, mental function, and work performance in patients with polycythaemia secondary to hypoxic lung disease. The procedure was well tolerated by all patients and no complications occurred.     

Effect of inhalation therapy with beclomethasone dipropionate on unspecific bronchial hyperreactivity in patients with asthma]

An effect of beclomethasone dipropionate (Beclocort-Polfa) was investigated in the group of 24 patients with atopic and non-atopic bronchial asthma who have shown unspecific bronchial hyperreactivity to histamine during the periods of remission. The drug was administered in the form of aerosol in a daily dose of 1.0 mg for 4 weeks. Provocative histamine dose was established with Bronchoscreen device (Jaeger) thrice:prior to the treatment, after 1 week of placebo therapy, and after 1 month of beclomethasone administration. Statistically significant increase in histamine dose for provocation of bronchospasm (p < 0.01) being nearly twice higher than the baseline value has been noted in patients treated with beclomethasone dipropionate aerosol. It advocates such a treatment in unspecific bronchial hyperreactivity independently of the type of the bronchial asthma.     

Hypnosis for Asthma—a Controlled Trial: A Report to the Research Committee of the British Tuberculosis Association*

An investigation of hypnosis in asthma was made among patients aged 10 to 60 years with paroxysmal attacks of wheezing or tight chest capable of relief by bronchodilators. One group of patients was given hypnosis monthly and used autohypnosis daily for one year. Comparisons were made with a control group prescribed a specially devised set of breathing exercises aimed at progressive relaxation. Treatment was randomly allocated and patients were treated by physicians in nine centres. Results were assessed by daily diary recordings of wheezing and the use of bronchodilators, and by monthly recordings of F.E.V.₁ and vital capacity. At the end of the year independent clinical assessments were made by physicians unaware of the patients'' treatment.There were 252 patients (127 hypnosis and 125 controls) accepted for analysis, but a number of them did not continue the prescribed treatment for the whole year: 28 hypnosis and 22 control patients failed to co-operate, left the district, or had family problems; one hypnosis and one control patient died. Seven hypnosis and 17 control patients were withdrawn as treatment failures, the difference between the two groups being statistically significant.As judged by analyses based on the daily “score” of wheezing recorded in patients'' diaries, by the number of times bronchodilators were used, and by independent clinical assessors, both treatment groups showed some improvement Among men the assessments of wheezing score and use of bronchodilators showed similar improvement in the two treatment groups; among women, however, those treated by hypnosis showed improvement similar to that observed in the men, but those given breathing exercises made much less progress, the difference between the two treatment groups reaching statistical significance. Changes in F.E.V.₁ and V.C. between the control and hypnosis groups were closely similar.Independent clinical assessors considered the asthma to be “much better” in 59% of the hypnosis group and in 43% of the control group, the difference being significant There was little difference between the sexes. Physicians with previous experience of hypnosis obtained significantly better results than did those without such experience.     

Contractile responses of the airways smooth muscles in experimental bronchial asthma; the role of interleukin 5 in formation of hyper-responsiveness of bronchial tubes

By mehanographic method, contraktile responses of the airways smooth muscles in experimental bronchial asthma in porpoises intact and incubated with interleykin-5, were studied. Sensitization of ovalbumin animals results in development of hypersensitivity to inhalation of the fiber with external attributes of infringement of bronchial passableness such as cough and a shortness of breath. Morphologically the process is accompanied by destruction of epithelium of the bronchial tubes, development of an immune inflammation in a bronchial wall, and a hypertrophy of the muscular layer. In the sensitized animals, development of hyper-responsiveness of the airways smooth muscles to histamine was obvious as shown in a significant decrease of the threshold concentration and an increase in the maximal amplitude of reduction. Interleukin-5 was shown to strengthen this process. Responses to holinergic and R2-adrenerdic influences practically did not change. The data obtained corroborate the hypothesis of development of the interleukin-5-depending bronchial hyper-responsiveness in absence of eosinophile damage in the mucous membrane of the bronchial tubes.     

Hypnotherapy for incontinence caused by the unstable detrusor.

Fifty incontinent women with proved detrusor instability completed 12 sessions of hypnosis (symptom removal by direct suggestion and "ego strengthening") over one month. This was continued at home with a prerecorded cassette, and all patients were followed up for at least six months. At the end of the 12 sessions 29 patients were entirely symptom free, 14 improved, and seven unchanged. Three months later cystometry in 44 of the patients showed conversion of the cystometrogram to stability in 22 and a significant improvement in a further 16; only six showed no objective improvement. Seven patients relapsed (three after bereavement). Further treatment was given and five out of six patients were rendered symptom free again. Patients with detrusor instability were not found to have a noticeably increased susceptibility to hypnosis. It is concluded that psychological factors are very important in "idiopathic" detrusor instability and that hypnotherapy is effective for incontinence due to this disorder.     

Sustained release choline theophyllinate in nocturnal asthma.

Nocturnal wheeze is common in patients with asthma, and slow release theophyllines may reduce symptoms. As theophyllines are stimulants of the central nervous system the effect of 10 days'' twice daily treatment with sustained release choline theophyllinate or placebo on symptoms, overnight bronchoconstriction, nocturnal oxygen saturation, and quality of sleep were studied in a double blind crossover study in nine stable patients with nocturnal asthma (five men, four women, age range 23-64 years; forced expiratory volume in one second (FEV1) 0.85-3.8 1; vital capacity 1.95-6.1 1). When treated with the active drug all patients had plasma theophylline concentrations of at least 28 mmol/l (5 micrograms/ml) (peak plasma theophylline concentrations 50-144 mmol/l (9-26 micrograms/ml]. Morning FEV1 was higher when treated with sustained release choline theophyllinate (2.7 (SEM 0.3) 1) than placebo (2.1 (0.3) 1) (p less than 0.01). Both daytime and nocturnal symptoms were reduced when the patients were treated with sustained release choline theophyllinate and subjective quality of sleep was improved (p less than 0.002). When treated with the active drug, however, quality of sleep determined by electroencephalography deteriorated with an increase in wakefulness and drowsiness (p less than 0.05) and a reduction in non-rapid eye movement sleep (p less than 0.005). Treatment with choline theophyllinate had no effect on either the occurrence or the severity of transient nocturnal hypoxaemic episodes or apnoeas or hypopnoeas. In conclusion, sustained release choline theophyllinate prevents overnight bronchoconstriction, but impairs quality of sleep defined by electroencephalography.     

The use of sedative-hypnotic drugs in a university teaching hospital.

We reviewed the charts of 476 patients admitted to a university teaching hospital to determine whether sedative-hypnotic drugs (SHDs) were being used excessively and to examine the use of SHDs as hypnotics. The frequency of medical and surgical indications for barbiturates and benzodiazepines or other minor tranquillizers as well as the use of such drugs were compared among different groups of patients and specialty wards. Of the patients 29% had a regular order and 40% had a PRN order; only 77% of the PRN orders were administered. A total of 215 patients (45%) received an SHD during their hospital stay, and 160 (34%) received the drug as a hypnotic. Medical indications accounted for 49% of the regular orders but only 2% of the PRN orders; moreover, 89% of all the PRN orders were for insomnia. On average, patients receiving SHDs as hypnotics were older (p less than 0.05) and stayed longer in hospital (p less than 0.01) than those who did not; however, no patient on the geriatric or pediatric ward received an SHD as a hypnotic during the hospital stay. The differences in use between patient groups may have been influenced by orientation of ward staff. Physicians should review their rationale for prescribing hypnotics and avoid routine orders on admission.     

Symptoms of respiratory tract infection and associated care-seeking in subjects with and without obstructive lung disease; The Tromso Study: Tromso 6

ABSTRACT: BACKGROUND: Respiratory tract infections (RTIs) may be more severe in those with asthma or COPD and these patients are more frequently in need of health care. The aim of the study was to describe the frequency of RTI symptoms in a general adult population and how care-seeking is associated with the presence of obstructive lung disease. METHODS: Cross-sectional data including spirometry and self-reported chronic diseases were collected among middle-aged and elderly subjects in the Tromso population survey (Tromso 6). Self- reported RTI symptoms, consultations and antibiotic use were the main outcome variables. Possible predictors of RTI symptoms were evaluated by multivariable logistic regression. RESULTS: Of the 6414 subjects included, 798 (12.4 %) reported RTI symptoms in the previous week. RTI symptoms were reported less frequently by subjects aged 75 years or above, than by those younger than 55 years (OR 0.5). Winter season (OR 1.28), current smoking (OR 1.60), low self-rated health (OR 1.26) and moderate to severe bronchial obstruction (OR 1.51), were also statistically significant independent predictors of RTI symptoms, but these variables did not predict RTI symptoms that had started within the previous seven days. Among subjects with RTI symptoms, 5.1 % also reported a consultation with a doctor. In those with bronchial obstruction by spirometry, who did not report asthma or COPD, this frequency was 2.4 %. Antibiotic treatment was reported by 7.4 % of the participants, among whom one third had consulted a doctor. Antibiotics were taken more frequently when asthma or COPD was reported (13.7 %), but not in subjects with bronchial obstruction who did not report these diseases (7.2 %). CONCLUSIONS: RTI symptoms seldom led to consultation with a doctor and not even in subjects with obstructive lung disease. This was in particular the case in subject who did not know about their obstructive lung disease. Strategies for early diagnosis of COPD and providing health care to subjects with such disease cannot rely on their doctor visits due to respiratory symptoms.

Respiratory symptoms and bronchial reactivity: identification of a syndrome and its relation to asthma.

Two postal questionnaire surveys were carried out among the adult population of Southampton aimed at clarifying the diagnostic criteria for asthma (study 1) and at testing the validity of symptoms so identified as diagnostic of bronchial hyper-reactivity (study 2). The questionnaires asked about respiratory symptoms and included three questions thought likely to disclose increased bronchial reactivity. Laboratory measurements on subsamples of respondents included spirometry and bronchial challenge with increasing doses of histamine till a concentration was reached provoking a fall of more than 20% (PC greater than 20) in forced expiratory volume in one second. In the first study no normal subject (that is, one who did not report shortness of breath or wheezing on the questionnaire) had a PC greater than 20 below 0.5 g/l. Of 51 subjects who reported shortness of breath or wheezing, or both, nine had a cluster of abnormalities consisting of one or more symptoms of bronchial irritability, nocturnal dyspnoea, and prolonged morning tightness together with PC greater than 20 values of 0.5 g/l or less. These symptoms in conjunction with a low PC greater than 20 were termed the bronchial irritability syndrome. In the second study bronchial challenge confirmed the close association of these symptoms with bronchial hyper-reactivity, all other subjects being less reactive to histamine. Only 27% of subjects with symptoms of the bronchial irritability syndrome had been diagnosed as asthmatic by their general practitioners. The bronchial irritability syndrome is a definable entity for epidemiological study and patient care.     

Effect of a previous voluntary deep breath on laryngeal resistance in normal and asthmatic subjects

We studied changes in both laryngeal resistance (Rla) and respiratory resistance (Rrs) after a voluntary deep breath in 7 normal and 20 asthmatic subjects. Rla was measured using a low-frequency sound method (Sekizawa et al. J. Appl. Physiol. 55: 591-597, 1983) and Rrs by forced oscillation at 3 Hz. In normal subjects, both Rla and Rrs significantly decreased after a voluntary deep breath (0.05 less than P less than 0.01). During methacholine provocation in the normal subjects, a voluntary deep breath significantly decreased Rrs (0.05 less than P less than 0.01, but Rla was significantly increased (0.05 less than P less than 0.01). In 10 asthmatic subjects in remission, a voluntary deep breath significantly increased Rrs (0.05 less than P less than 0.01) but significantly decreased Rla (0.05 less than P less than 0.01). In another 10 asthmatic subjects during spontaneous mild attacks, a voluntary deep breath significantly increased both Rrs and Rla (0.05 less than P less than 0.01). The present study showed that without obvious bronchoconstriction, Rla decreased after a voluntary deep breath in both normal and asthmatic subjects but, with bronchoconstriction, Rla increased in both groups. Subtraction of the change in Rla from Rrs gives the change in Rrs below the larynx (Rlow). Rlow changed little or decreased in normal subjects and increased in asthmatic subjects, irrespective of base-line bronchomotor tone. These results suggest that airway response below the larynx after a voluntary deep breath differentiates patients with bronchial asthma from normal subjects.
