1991—1993年中国5岁以下儿童肺炎死亡监测结果

为了解我国５岁以下儿童肺炎的死亡情况，以随机抽样方法，对１９９１～１９９３年全国８１个市县８５５万５岁以下儿童进行肺炎死亡监测。结果表明，肺炎仍是我国儿童死亡的最重要疾病。全国及农村不论婴儿、１～４岁，还是０～４岁儿童，肺炎均为第１位死因，占同年龄儿童总死亡的２０．０％～２５．０％。１９９１～１９９３年全国平均５岁以下儿童肺炎死亡率为１３１９．２／１０万，城市为２６６．４／１０万，农村为１５６２．２／１０万（为城市的６倍）。农村儿童因肺炎死亡者６３．０％死在家中，５０．０％仅接受门诊治疗，未治疗占１８．５％。监测结果表明，近１０年来，城市儿童肺炎死亡率有所下降，但农村儿童肺炎死亡率仍居高不下，欲实现２０００年全国５岁以下儿童死亡率下降三分之一的目标，降低儿童肺炎死亡乃是当务之急。

Assessing the roles of demographic,social, economic,environmental, health-related,and political factors on risk of osteoporosis diagnosis among older adults

Summary

Until now, there have been only a few retrospective studies that focused on the outcomes of sandwich vertebral bodies (SVBs). This is a long-term retrospective cohort study to investigate the SVBs. We found that although patients with SVBs had a relatively high risk of developing new fractures after VA, the incidence rate of new fractures was not significantly different from that of the control group. However, the statistical power of this study was very limited. Therefore, and because the refracture rate in these patients is substantial, routine long-term monitoring of patients after VA for osteoporosis is strongly recommended.

Background

Sandwich vertebral bodies (SVBs) are intact unaugmented vertebral bodies between two previously augmented vertebrae. Until recently, only a few studies have reported the outcomes and strategies for SVBs. This retrospective cohort study aimed to describe the clinical features and incidence of new fractures in patients with SVBs.

Methods

The clinical data were collected from 179 patients with 237 symptomatic osteoporotic vertebral compression fractures who underwent vertebral augmentation (VA). Among them, 23 patients with 24 levels of SVBs were included. Spinal radiographs (X-ray and CT) of all patients were evaluated prior to surgery 1 day after primary VA and during follow-up.

Results

All patients successfully underwent PKP with an average follow-up period of 21.48 months. Asymptomatic cement leakage occurred in four patients (17.4%), and eight patients (34.8%) developed new fractures following primary PKP, including four sandwich, six adjacent, four remote vertebral fractures, and one re-collapse of cemented vertebrae. The incidence of new fractures in the SVB and control groups was 16.7% (4/24) and 13.0% (6/46), respectively, but there was no significant difference.

Conclusions

Although patients with SVBs had a relatively high risk of developing new fractures after VA, the incidence rate of new fractures was not significantly different from that of the control group. However, the statistical power of this study was very limited. Therefore, and because the refracture rate in these patients is substantial, routine long-term monitoring of patients after VA for osteoporosis is strongly recommended.

     

A study of field-based methods for diagnosing reproductive tract infections in rural Yunnan Province, China

Reproductive tract infections are a significant cause of poor health among rural Chinese women. This study assesses the accuracy of simple, field-based methods of diagnosing five reproductive tract infections (trichomonas, candida, bacterial vaginosis, gonorrhea, and chlamydia) in two rural Chinese counties, using "gold standard" laboratory diagnosis as the reference. Self-reported symptoms and clinical examination proved inadequate for making accurate diagnoses, because many infected women show no symptoms or are infected with two or more conditions. The use of simple tests such as KOH staining, wet mount, Gram's stain, and pH of discharge greatly improved diagnostic accuracy, especially for candida and trichomonas, the two most common infections. Promoting the use of such diagnostic approaches by rural Chinese medical and family planning health providers would reduce the prevalence and severity of these preventable and easily treated infections.     

癫痫儿童生活质量的研究

目的研究癫痫儿童的生活质量。方法应用美国癫痫生活质量量表，对１９２例癫痫儿童进行生活质量的评估，探讨影响因素并与正常儿童进行比较。结果癫痫儿童的生活质量明显低于正常儿童，主要表现在对发作的恐惧、长期用药的担忧、认知功能的障碍及社会交往的困难。即使发作已被控制，其生活质量并无明显改善。生活质量高低因发作类型不同而各异。结论对癫痫儿童应加强综合治疗，特别要进行心理干预，才能提高其生活质量。

中等剂量糖皮质激素治疗激素敏感肾病综合征复发患儿的前瞻性随机对照研究

目的比较不同剂量糖皮质激素（glucocorticoid，GC）治疗激素敏感肾病综合征（steroid sensitive nephrotic syndrome，SSNS）复发患儿的有效性及药物不良反应。方法选取2017年11月至2019年12月在首都儿科研究所附属儿童医院肾脏内科住院并诊断为SSNS复发的患儿67例为研究对象，随机分为中量GC组（n=32）和足量GC组（n=35）。比较两组患儿尿蛋白转阴、6个月内复发和激素不良反应发生情况。结果中量GC组尿蛋白转阴率为91%，足量GC组为94%，两组比较差异无统计学意义（P>0.05）。6个月内中量GC组复发率为41%，足量GC组为36%，差异无统计学意义（P>0.05）。随访6个月时，中量GC组患儿泼尼松累积量为（87±18）mg/kg，显著低于足量GC组患儿［（98±16）mg/kg］（P=0.039）；中量GC组6%患儿出现体重异常增加，显著低于足量GC组（33%）（P=0.045）。logistic回归分析显示，入组复发时泼尼松剂量≥10 mg/隔日，是随访6个月内SSNS患儿复发的危险因素（P=0.018）。结论对于SSNS复发患儿，应用中剂量GC治疗方案，其6个月内诱导缓解、复发情况较足量GC治疗方案无显著差异，而6个月内GC累积剂量和不良反应较小。     

Adriamycin-methotrexate high dose versus adriamycin-methotrexate moderate dose as adjuvant chemotherapy for osteosarcoma of the extremities: a randomized study

Adjuvant chemotherapy comprising Adriamycin (ADM) and Methotrexate (MTX) with Citrovorum Factor (CF) was administered on a randomization basis to 2 groups of patients with osteosarcoma after surgical ablation of the primary tumor. One group received high dose MTX (regimen I) and the other moderate dose MTX (regimen II). In both groups a short period of heparin treatment was also administered to prevent neoplastic emboli during surgery. All patients were free of metastasis at the beginning of therapy. The efficacy of therapy was determined by recording the percentage of continuously disease-free patients. This was compared to the disease-free survival in 132 patients previously treated with other ADM or ADM-MTX regimens and to a group of 39 patients treated during this period with amputation only. The latter did not receive adjuvant chemotherapy for a variety of reasons and are equated to a concurrent control group. Over the ensuing 27–66 months, 31 of 56 patients (55%) treated with regimen I and 25 of 50 (50%) treated with regimen II were disease-free. The overall disease-free survival in both regimens was 53%. This is similar to the 132 patients treated with previous adjuvant chemotherapy protocols (45–50%). However, the percentage of continuously disease-free patients treated with adjuvant chemotherapy was significantly better than the 39 patients (12%) treated contemporaneously with surgery only (P < 0.0005). Survival in the latter is similar to that of historical control patients. These results do not suggest any change in the natural history of osteosarcoma and reveal benefits which may accrue with adjuvant chemotherapy. These results also demonstrate that in adjuvant treatment of osteosarcoma performed with ADM and MTX the high and the moderate doses of MTX are equally efficacious.
