Hypnotizability and hypnoanalgesia: hypnotizability of patients using hypnoanalgesia during surgery.

We administered the Stanford Hypnotic Suggestibility Scale (Form A) (SHSS:A) to 10 patients from a population of 20 who had undergone surgery in the previous 10 years using hypnoanalgesia as the sole or principal analgesic agent. Time since surgery ranged from 2 days to 10 years. Scores on the SHSS ranged from 5 (medium susceptibility) to 12 (high susceptibility) with a mean of 8.6, significantly higher than the SHSS:A normative group (p less than .001). The relationship between severity of surgery and the use of hypnoanalgesia as the sole or principal analgesia was significant for our patient population (N = 20) but not for our patient sample (N = 10).

Anulus fibrosus in bulging intervertebral disks

In this investigation the association of radial tears of the anulus fibrosus and bulging of the intervertebral disk was studied. An index of disk bulging was measured in sagittal anatomic sections in 149 lumbar disks from 31 cadavers. The indexes of disk bulging were correlated with stages of disk development and the presence of an annular tear. The largest disk-bulging indexes were always associated with radial tears of the anulus. Eighty-four percent of the disks with radial tears had disk-bulging indexes greater than 2.5 mm. Most normal adult disks had an index of less than 2.5 mm. The results challenge the concept that the anulus fibrosus is intact in bulging disks, although ruptured in herniated disks.     

Accurate counting of low numbers of leukocytes. Use of flow cytometry and a manual low-count chamber.

The leukocyte depletion that current filters make possible in erythrocyte and platelet preparations can result in leukocyte concentrations too low to be counted accurately by automated and standard manual methods. A recently described method for counting low numbers (1 to 10 x 10(6) per L) of leukocytes by flow cytometry and the use of a manual low-count chamber on 25 venous samples serially diluted to 1:1,000 were evaluated. The results show that both methods for counting leukocytes can reliably determine counts of 1 to 10 x 10(6) leukocytes/liter (a three-order of magnitude reduction from venous blood) in terms of order of magnitude but lack accuracy for specific measurement. The flow cytometric method is more expensive, less readily available, and suffers from greater sample variability. Use of a low-count chamber is a superior technique to evaluate and maintain quality control of methods for leukocyte depletion, resulting in a final leukocyte concentration of 1 to 10 cells per microliter.     

痛

黑暗!黑暗!!黑暗!!!这样的世界看不到半点光明。孤独的舞者终究还是孤独地倒下,然后又孤独地消失。黑暗呀,为什么老是缠绕着我?一声“妈妈”划破了天际,却也突不出黑暗的包围。谁来应我一声呀,妈妈,你在哪里呀?我的心在不停地挣扎,告诉自己:“不怕,不怕。”可这是在黑暗里呀,周     

Early stage nasopharyngeal carcinoma: radiotherapy dose and time factors in tumor control

OBJECTIVE: To evaluate radiotherapy dose and length of treatment in the control of early stage nasopharyngeal carcinoma (NPC) treated with a combination of external radiotherapy and brachytherapy, MATERIALS & METHODS: We reviewed the records of 133 patients with early stage nasopharyngeal carcinoma (stage I or II, AJC/UICC staging system) who received definitive radiotherapy in Chang Gung Memorial Hospital from 1979 to 1991. The median follow-up time was 7.1 years with a minimum of 2 years. All patients were treated with megavoltage external radiotherapy to the nasopharynx area (63-72 Gy) followed by high dose rate intracavitary brachytherapy (5-16.5 Gy in one to three fractions, spaced 1-2 weeks apart). The median total dose and time of irradiation was 75 Gy (69.8-81.4 Gy) and 11.6 weeks (7.8-20 weeks) respectively. Survival analysis was used to examine the effect of several variables on prognosis. RESULTS: The 5-year rates were 86.4% for local control, 84.7% for disease free survival, 88.5% for actuarial survival and 84.2% for overall survival. The treatment group (combination of time and dose of irradiation) was the most important prognostic factor according to Cox's proportional hazard model. Patients receiving radiation at a total dose of < or = 75 Gy completed in < 12 weeks showed the best prognosis. CONCLUSION: Treatment time and total treatment dose are both important factors in treating early stage NPC. Decreasing the total radiation time to < 12 weeks and not exceeding a radiation dose of 75 Gy gave the best results.
