Relationship between self-rating and polygraphic sleep parameters — analysis of compiled data from 12 young Japanese adults —

An examination of the relationship of the self-rating sleep score to polygraphic sleep parameters was conducted. The self-rating sleep questionnaire, OSA, includes five sleep quality factors: sleepiness (Fl), sleep maintenance without interruption (F2), worry about daily life or poor emotional condition (F3), integrated or perceived sleep feeling (F4) and sleep initiation or induction (F5). Polygraphic sleep parameters including each sleep stage in minutes were used. If intercorrelation coefficients exceeded 0.8, only one of the related parameters was selected for multivariate analysis. Twelve male students slept a total of 88 nights, among which the first night was not included, in an experimental room. When absolute values of Spearman’s rank correlation coefficient of not less than 0.4 were tentatively selected, the following pairs were extracted: F2 score and S1 (-0.423) or S3+S4 (0.409), F5 score and sleep latency (-0.439). Deeper sleep was closely associated with sleep maintenance without interruption. Agreement between self-rating and a polygraphic sleep parameter was recognized between the F5 score and sleep latency. Each OSA factor score was predicted by other polygraphic sleep parameters using multiple regression analysis. MT significantly contributed to the Fl, F3 and F4 scores. The number of stage shifts per night significantly contributed to the Fl and F3 scores, and the number of sleep spindles significantly contributed to the F5 score. Though prediction of sleep quality by polygraphic sleep parameters is limited, the association between concrete subjective and objective sleep parameters was clarified as mentioned above, and their practical meaning was partially elucidated.     

Laryngeal cancer and blood selenium levels

Blood selenium concentrations in 43 patients with laryngeal cancer and 47 normal subjects were determined by atomic absorption spectrophotometry. No significant differences in selenium values were observed in sera from the cancer patients when compared with controls, but there were significant differences between patients with advanced (T4) supraglottic cancers and the normal controls. These results suggest that lower blood selenium levels in this latter group of laryngeal cancer patients may be a consequence of their disease rather than its cause.

Patients' and doctors' perception of long-term morbidity in patients with testicular cancer clinical stage I

Patient-based questionnaires were designed with the aim to identify and rank long-term somatic and psychosocial morbidity in patients with low-stage testicular cancer. A further intention was to compare patients' assessments with experienced doctors' general opinion on quality of life items in cured testicular cancer patients. In pilot study I, 103 tumour-free patients ranked items of physical and psychosocial morbidity after having had various kinds of treatment. Though the ranking procedure appeared to cause some difficulties amongst the patients and subsequently was abandoned, the results indicated considerable differences between the patients' and doctors' evaluations. In pilot study II patients were asked to score the different items. The questionnaire of pilot study II was completed by 107 patients from the Norwegian Radium Hospital (NRH) and 99 relapse-free patients from the Royal Marsden Hospital (RMH) with testicular cancer stage I at least 1 year after infradiaphragmatic radiotherapy (n = 94) or adjuvant chemotherapy (2 cycles,n=26), or patients who had been followed on the surveillance program (n = 86). A total of 93 doctors completed a similar questionnaire, thereby expressing their general opinion on long-term morbidity in comparable testicular cancer patients as seen during routine clinical follow-up. Both the irradiated patients and those on the surveillance program reported slight degrees of Raynaud-like phenomena, neurotoxicity and ototoxicity, most probably representing background morbidity in an age-matched general male population. Doctors tended to underestimate their patients' somatic morbidity, but often overestimated the degree of psychological distress, in particular in patients on the surveillance program. Significant differences between RMH and NRH patients with regard to sexual problems and to leisure time activity may be explained by cultural differences in the two countries. The items presented in the questionnaire used identify important issues for patients cured of testicular cancer which may be used in future multicentre trans-cultural studies assessing these patients' quality of life. This will provide sufficient data for psychometric testing and, together with the findings from patients' free comments, support the final design of a testicular cancer quality of life module.     

GnRH analogues as an adjuvant therapy for ovarian cancer patients.

OBJECTIVES: Lowering gonadotropin levels with gonadotropin-releasing hormone (GnRH) analogues in patients with ovarian cancer remains open to debate. The aim of this study was to assess the results of treatment in stage III and stage IV ovarian cancer patients who had surgery supplemented with chemotherapy, radiotherapy, and GnRH analogues. Gonadotropin levels were monitored during treatment. METHODS: The study group comprised 69 patients aged 27-70 years, stratified according to the type of treatment. The overall disease-free, 5-year survival rates and the frequency of remissions were analyzed. Hormonal tests [follicle-stimulating hormone (FSH) and luteinizing hormone (LH)] were performed in 58 patients. Associations were checked between gonadotropin levels, clinical findings, and survival. The results were statistically compared. RESULTS: Statistically significant differences were noted when chemotherapy was supplemented with GnRH analogues and/or radiotherapy. Administration of GnRH analogues resulted in significantly lower levels of LH than of FSH. Levels of FSH were significantly lower in patients surviving at least 5 years or in complete remission at the time of this study. CONCLUSIONS: Combined therapy can produce favorable results in late-stage ovarian cancer, and GnRH analogues have an important role in treatment strategy.

头针对超早期局部脑缺血大鼠的影响

目的观察头针治疗超早期脑梗死的效果并探讨作用机理。方法用 SD 大鼠制做动脉血栓性大脑中动脉局灶性脑梗死动物模型,术后2h 分别予通脑活络针刺法及尿激酶溶栓法治疗,并设模型组与假手术组。各组分别于栓塞后6h、3天及7天测量神经功能损害积分、脑梗死容积百分比、脑组织含水量、脑组织一氧化氮(NO)含量、总超氧化物歧化酶(SOD)活力及丙二醛(MDA)含量。结果术后经针刺或溶栓治疗3天及7天大鼠神经功能损害评分、脑梗死容积百分比、脑组织含水率较模型组显著减少,7天时针刺组与溶栓组神经功能损害评分、脑梗死容积百分比、脑组织含水率的比较差异无显著性。栓塞后针刺组各时间点脑组织总 SOD 活力明显高于模型组(P<0.05),而 MDA 含量明显低于模型组(P<0.05)。结论超早期通脑活络针刺法治疗急性脑梗死有明显疗效。减少氧自由基的产生、直接对神经元起到保护作用可能是其作用机理之一。
