MANAGEMENT OF UNCONTROLLED GLAUCOMA WITH THE MOLTENO SYSTEM

In glaucomatous eyes refractory to medication, laser techniques and conventional drainage surgery, intraocular pressure is often high, and visual loss rapid. In this situation a reliable, robust artificial outflow system is required. Molteno has evolved a plastic tube and plate device combined with a fibrosis suppression medication regimen. Thirty-eight eyes of 32 patients with uncontrolled glaucoma were treated with the Molteno system. Six months after operation mean intraocular pressure had been reduced from 41.0 ± 13.6 to 16.2 ± 5.6 mmHg. Eighteen eyes had pressures of 20 mmHg or less on no hypotensive therapy, 17 on reduced treatment. Three eyes had a pressure of 21 to 35 mmHg on treatment at six months. The 13 aphakic eyes responded as well as 25 phakic eyes. Five eyes with rubeotic glaucoma demonstrated pressures of less than 20 mmHg without therapy, four eyes with traumatic glaucoma required continuing medication with three having pressures below 22 mmHg. Of the seven eyes with uveitic glaucoma, one was lost, two required maintenance therapy; five of six surviving eyes had pressures below 20 mmHg. Fifteen eyes with congenital or juvenile glaucoma achieved pressures below 20 mmHg, three of these with timolol drops, three with timolol and acetazolamide, and nine with no treatment. While seven of seven eyes with refractory primary open-angle glaucoma attained pressures below 20 mmHg. all seven needed continuing mild hypotensive therapy. Eleven eyes underwent a one-stage procedure, while 27 eyes required a two-stage operation. Twenty-eight eyes received fibrosis suppression medication after the second stage, and 24 maintained or improved their preoperative visual acuity. Results have been encouraging: in general the Molteno system is recommended as the second drainage operation in all glaucomatous eyes in which conventional therapy has failed, and as the primary surgical procedure (after laser techniques) in eyes with rubeotic and uveitic glaucoma. Ciliary body destructive procedures should be restricted to control of symptoms in blind eyes.     

Limbus-based versus Fornix-based conjunctival flap in filtering surgery

Summary A randomized prospective study was performed to compare the results of filtering surgery using a Limbusbased versus a Fornix-based conjunctival flap. The wound closure of the Fornix-based flap was performed using a running 10/0 nylon suture at the limbus. No statistical significant difference of IOP regulation was found between the two groups. There was a tendency of reduced occurrence of shallow anterior chamber and of less vascularized filtering blebs in the Fornix-based technique.

Impact of cosmetic care on quality of life in breast cancer patients during chemotherapy and radiotherapy: an initial randomized controlled study

BACKGROUND: Breast cancer is the most common cancer in women and therefore represents a major problem in public health. Data from patients' self-report questionnaires provide valuable information about the side-effects that patients may view as having a significantly detrimental impact on their quality of life (QOL) and yet are not always recognized as important by healthcare professionals. Cosmetology is a specific care for patients and there is actually no scientific evidence regarding effects on QOL for women with breast cancer. OBJECTIVE: The purpose of this study is to assess the impact of cosmetic care on QOL in breast cancer patients during chemotherapy and radiotherapy. METHODS: We developed a prospective, multicentre, randomized, controlled study including 27 patients. All the patients had to fill in a French-validated dermatologic specific quality-of-life questionnaire to compare the QOL of the two groups, the cosmetic group and the control group, at three different times of the adjuvant treatment. RESULTS: The results show a statistically significant difference between the cosmetic group and the control group in two areas of QOL: mood state and self-perception of the disease. CONCLUSION: This study emphasizes the interest of cosmetic care in breast cancer patients. However, further larger trials are needed to confirm this study.     

Computerised and technical navigation in total knee-arthroplasty

Abstract The objective of the study was to evaluate the precision, concordance, practicability and the early clinical outcome of the use of a computerised navigation system in a comparative study with a group of 100 patients. Two groups of 50 patients each underwent implantation of a bicondylar knee prosthesis either by means of the freehand navigation system or by means of technical instrumentation. We found that the computerised navigation system provided a higher precision than the technically instrumented implantation: 94% of the prostheses implanted with the navigation system have an alignment within a range of -3° to 3° on of the Mikulicz line. Only 46% of the patients operated by means of the technical instrumentation reached this aspired result. Furthermore, the navigation system showed smaller ranges in the deviation of the aspired alignment. The radiological and computer-modeled alignment values differed both pre- and postoperatively, but to a larger extent before surgery. The varus or valgus deviations of the axis were more distinct radiologically under the weight of the patient’s body than in the computer model. The clinical outcome examined by the use of the HSS score after a mean followup of 7 months is good in both groups, and without significant differences. On average, the duration of surgery was 13 minutes longer in the computerised navigation group. We conclude that the benefit of the computerised navigation system is represented by the high improvement of precision. Achieving early clinical results identical to those in the technical instrumentation group, we expect a reduction of aseptic loosening in the computerised navigation group.     

Natural killer cell activity and quality of life were improved by consumption of a mushroom extract, Agaricus blazei Murill Kyowa, in gynecological cancer patients undergoing chemotherapy

A mushroom extract, Agaricus blazei Murill Kyowa (ABMK), has been reported to possess antimutagenic and antitumor effects. Here, we investigate the beneficial effects of ABMK consumption on immunological status and qualities of life in cancer patients undergoing chemotherapy. One hundred cervical, ovarian, and endometrial cancer patients were treated either with carboplatin (300 mg / m(2)) plus VP16 (etoposide, 100 mg / m(2)) or with carboplatin (300 mg / m(2)) plus taxol (175 mg / m(2)) every 3 weeks for at least three cycles with or without oral consumption of ABMK. We observed that natural killer cell activity was significantly higher in ABMK-treated group (ANOVA, n = 39, P < 0.002) as compared with nontreated placebo group (n = 61). However, no significant difference in lymphokine-activated killer and monocyte activities was observed in a manner similar to the count of specific immune cell populations between ABMK-treated and nontreated groups. However, chemotherapy-associated side effects such as appetite, alopecia, emotional stability, and general weakness were all improved by ABMK treatment. Taken together, this suggests that ABMK treatment might be beneficial for gynecological cancer patients undergoing chemotherapy.     

眼轴线后部眶容积增大与眼球内陷比值的测定研究

目的:通过测量眼眶爆裂性骨折伴有眼眶扩大患者的后部眼眶容积、观察眼球内陷出现的时间及程度,研究后部眶容积扩大与眼球内陷的关系比值,为病情预测和眶内填充手术提供比较精确的参考数据。方法:将96例患者按发病时间分为早期病例组(60例、受伤时间1周以内)和晚期病例组(36例、受伤时间3个月以上),早期组除进行后部眼眶容积测量外,分别于1周、2周、3周测定眼球突出度(相差>1mm为阳性),记录眼球内陷出现时间,用卡方检验进行统计学分析;晚期组测量后部眶容积增大值和眼球内陷量,对其相关性采用Pearson统计方法进行统计学分析,并得出回归方程及相关系数。结果:早期组60例患者中,(58.33%)例患者在1周内出现眼球内陷,4(880%)例在2周内出现内陷,3周时有5(388.33%)例呈现出内陷;2周时出现眼球内陷的例数与1周时有显著性差异(χ2=62.484,P<0.001),2周时出现眼球内陷例数与3周时无差异(χ2=1.563,P>0.05),1周时出现眼球内陷例数与3周时有显著差异(χ2=76.885,P<0.001),后部眶容积增大与眼球内陷的比值约为1.0,两者之间呈正相关(r=0.994,P<0.001),即后部眶容积每增加1ml,产生1.0mm的眼球内陷。结论:眼球内陷通常于伤后2周～3周出现,3个月时趋向稳定;后部眶容积增大与眼球内陷产生比值为1.0,呈正相关;后部眶容积扩大与眼球内陷比值可预测发生眼球内陷的可能性和程度,为手术矫正眼球内陷提供可靠、精确的参考,具有十分重要的临床指导意义。     

护士执业权及其法律保护初探

护士执业权是依法取得护士执业证书,以护士名义为社会提供护理服务的医务人员进行护理工作的权利和相关权益,是护士执业规则的核心内容,护士执业权属于公民劳动权益的范畴,是一种具有职业特权性质的特殊劳动权,应立法保护。本文试图通过对护士执业权的法理初步探讨,结合目前存在的侵害护士执业权的突出现象分析,提出保护该项权利的立法建议。
