输卵管通液术与子宫内膜异位症的关系

目的：探讨输久管通液术与子宫内膜异位症的关系。方法：直视下对104例输卵管性不孕患地输卵管通液术,收集输卵管流出液作巴氏染色进行宫内膜细胞的检查。结果：发现子宫内膜异位症29例（27．88％）,检出宫内膜细胞60．67％（63／104）,对月经周期中不同时间通液进行比较,发现各时间段宫内膜细胞的检出率之间差异无显性意义（P＞0．05）。结论：通液术将宫内膜细胞带入盆腔可能是造成子宫内膜异位症的原因,但不同时间通水宫内膜细胞的检出无显差异。     

长期家庭氧疗对慢性阻塞性肺疾病患者心理情绪的影响

目的探讨长期家庭氧疗(LTOT)对慢性阻塞性肺疾病(COPD)低氧血症患者心理情绪的影响。方法31例COPD低氧血症患者用医院焦虑和抑郁情绪表(HAD)进行心理情绪评分。然后分为LTOT组17例和对照组14例。LTOT组的氧流量0.5～2.5L/min,每日吸氧时间≥15h(包括睡眠时间);对照组除未进行LTOT外,其余治疗与氧疗组相同。两组年龄、性别、肺功能和动脉血气无明显差别。1年后分别复查HAD评分。结果LTOT组焦虑评分由治疗前的14.35±3.81下降到1年后的9.65±3.83(P<0.01),抑郁评分由治疗前的13.18±4.50下降到1年后的9.06±2.79(P<0.01);对照组焦虑和抑郁评分均无明显变化。1年后LTOT组的焦虑及抑郁评分分别与对照组比较明显改善。1年后LTOT组除动脉血氧分压与对照组有显著差异外,动脉血二氧化碳分压、PH值及肺功能均无显著差异。结论LTOT能改善COPD低氧血症患者的心理情绪。

Long-Term Functional Outcomes and Quality of Life at Minimum 10-Year Follow-Up After Fixed-Bearing Unicompartmental Knee Arthroplasty and Total Knee Arthroplasty for Isolated Medial Compartment Osteoarthritis

BackgroundThe aim of this study is to compare the long-term functional outcome and quality of life between total knee arthroplasty (TKA) and fixed-bearing unicompartmental knee arthroplasty (UKA) for the treatment of isolated medial compartment osteoarthritis.MethodsBetween 2000 and 2008, a total of 218 patients underwent primary UKA at our tertiary hospital. A TKA group was matched through 1:1 propensity score matching and adjusted for age, gender, body mass index, preoperative knee flexion, and function scores. All patients had medial compartment osteoarthritis. The patients were assessed with the range of motion, Knee Society Knee Score and Knee Society Function Score, Oxford Knee Score, Short Form-36 physical component score (PCS) and mental component score preoperatively, at 6 months, 2 years, and 10 years. Patients’ satisfaction, expectation fulfillment, and minimal clinically important difference were analyzed.ResultsThere were no differences in baseline characteristics between groups after propensity score matching (P > .05). UKA had greater knee flexion at all time points. Although the Knee Society Function Score was superior in UKA by 5.5, 3, and 4.3 points at 6 months, 2 years, and 10 years, respectively (P < .001), these differences did not exceed the minimal clinically important difference (Knee Society Knee Score 6.1). There were no significant differences in the Oxford Knee Score and Short Form-36 physical component score/mental component score. At 10 years, similar proportions of UKA and TKA were satisfied (90.8% vs 89.9%, P = .44) and had expectation fulfillment (89.4% vs 88.5%, P = .46). Between 2 and 10 years, all function scores deteriorated significantly for both groups (P < .01).ConclusionUKA and TKA are excellent treatment modalities for isolated medial compartment osteoarthritis, with similar functional outcomes, quality of life, and satisfaction at 10 years.     

Observational study of pre-operative intravenous iron given to anaemic patients before elective cardiac surgery

Cardiac surgical patients with anaemia experience increased morbidity and mortality. Iron deficiency is the most common cause of pre-operative anaemia in this group. We designed and implemented the Cardiff Pathway, a pre-assessment and treatment pathway to identify cardiac surgical patients with anaemia and iron deficiency. Patients identified with anaemia and/or iron deficiency (Hb < 130 g.l^-1 and ferritin < 100 μg.l^-1) were offered intravenous iron infusion 20 mg.kg^-1 pre-operatively. Treatment success was defined as Hb ≥ 130g.l^-1 on the day of surgery. We analysed data from 447 patients: 300 (67%) were not anaemic; 75 (17%) were anaemic and treated with intravenous iron; and 72 (16%) were anaemic and not treated. Haemoglobin concentration increased in successfully treated anaemic patients by a mean (95%CI) of 17 (13–21) g.l^-1 and they received a median (IQR [range]) of 0 (0–2 [0–15]) units of blood peri-operatively. Transfusion was avoided in 54% of the successfully treated anaemic patients, which was significantly more than the unsuccessfully treated anaemic (22%, p = 0.005) and untreated anaemic (28%, p = 0.018) patients and similar to non-anaemic patients who received a median (IQR [range] of 0 (0–1 [0–16])) units of blood and, 63% avoided transfusion). Mean (95%CI) Hb fell between pre-assessment and surgery in the untreated anaemic (-2 (0 to -4) g.l^-1) and non-anaemic groups (-2 (-1 to -3) g.l^-1). Twenty-one (7%) of the non-anaemic group became newly anaemic waiting for surgery. The Cardiff Pathway reliably identified patients with anaemia and iron deficiency. Anaemic patients who had their Hb restored to normal after treatment required less blood peri-operatively and over half of them required no transfusion at all.
