地震伤中小腿开放性骨折的特点及治疗经验

四川汶川发生里氏8.0级地震后,第二军医大学第七医疗队于5月15日凌晨抵达重灾区江油市,至7月7日离开54d中,共处理开放性胫腓骨骨折43例.山于地震伤在不同时期、不同震级、不同地理环境及建筑物条件下都有其不同的特点,加上胫腓骨开放性骨折的高致残率(截肢、感染、肢体短缩)在地震伤中的高发生率[1],故将这43例的病例特点及我们的救治体会总结如下.     

两种阴道缩窄术矫正阴道松弛症的疗效分析

目的探讨改良阴道后壁修补术和阴道后壁环肌紧缩术的手术要点和效果,评价两种手术的优点及适应证。方法将42例不同程度阴道松弛的患者分为两组,其中24例行改良阴道后壁修补术,18例行阴道后壁环肌紧缩术,分析观察两组患者手术时间、术中出血量、术后伤口愈合情况,1年后评价两组患者的性生活满意度及阴道的松紧度。结果两种手术方法的手术时间、术中出血量及术后伤口愈合情况无明显差异,但1年后的远期效果包括性生活满意度和阴道的松紧度有明显差异。结论矫正阴道松弛症的目的不仅要达到解剖的恢复,更重要的是恢复功能。要根据患者的实际情况选择最佳的手术方法(A组优于B组)。

Travel distance, age, and sex as factors in follow-up visit compliance in the post-gastric bypass population

BACKGROUND: There is no consensus regarding the optimal rate of follow-up in the post-bariatric surgery patient population. METHODS: The records of all patients who underwent laparoscopic Roux-en-Y gastric bypass from 2001 to 2003 were reviewed. Using patient zip codes, travel distances were calculated between the patients' places of residence and our clinic. Patients were then assigned to 1 of 3 cohorts according to the following distances: (1) < 50 miles, (2) 50 to 100 miles, and (3) > 100 miles. Patient compliance with follow-up appointments at 3 weeks, 3 months, 6 months, 9 months, and 12 months was analyzed. Linear trends were identified using the Mantel-Haenszel test. Age and sex were analyzed as possible predictors of compliance using the chi(2) test. P values < .05 were considered statistically significant. RESULTS: The study group comprised 150 patients (127 females and 23 males). The 3 cohorts contained 115, 21, and 14 patients, respectively. All patients in each cohort were compliant with the 3-week follow-up appointment. Although there were differences in compliance between cohorts at each of the remaining appointments, only the 9-month (70.3% vs 61.9% vs 35.7%) visit showed statistical significance (P = .035). The 6-month visit trended toward significance (85.2% vs 76.2% vs 64.3%; P = .088). Males were more likely to be compliant with the 12-month follow-up (P = .040). When controlling for sex, travel distance was also a predictor of compliance at this follow-up visit (P = .024). Age was not predictive of compliance (P = .827). CONCLUSION: Based on our findings, we conclude that travel distance from the clinic does not significantly affect compliance at the initial follow-up, 3-month, and 12-month appointments. However, distance does tend to affect compliance at the 6-month appointment and significantly affects compliance at the 9-month appointment. Males are more likely to be compliant at the 12 month follow-up visit. We must continue to strive for 100% follow-up in our post-bariatric surgery patients.     

Pituitary adenomas: Trans‐sphenoidal experience of 300 cases

Objective: The main aim of the present study was to examine the effectiveness and complication rate of the 1 cm right‐sided unilateral sublabial trans‐sphenoidal surgery for patients with pituitary adenoma equal to or greater than 5 mm in diameter. Method: A total of 350 patients were surgically treated for pituitary adenomas between December 1999 and December 2003 in an academic neurosurgical unit in China. Three hundred patients (86%) were treated with the 1‐cm right‐sided unilateral sublabial trans‐sphenoidal approach. The mean age of patients was 43 years (range 10–78 years) and female patients accounted for 59% of the total. One hundred and ninety‐six (64%) patients had functioning endocrine tumours and 104 (36%) patients had non‐functioning tumours or macroadenomas. Tumours which were outside this simple and basic classification were excluded from the study. Results: There were no operative mortalities. One patient developed hypopituitarism and 16 (5%) developed transient diabetes insipidus that required pituitrin treatment. The remission rate for macroadenoma was 85% and that for microadenoma was 98.5% during a medium term follow‐up of 1–5 years. One hundred and fifteen patients had prolactin secreting tumours and 90.4% achieved endocrine remission. Fifty‐six patients had growth hormone secreting tumours and 75.4% achieved endocrine remission. Preoperatively, one hundred and fifty‐one patients presented with visual impairment and 148 (98%) achieved a documented improvement in visual acuity. The mean duration of hospital stay was 4 days (range 3–7 days). Conclusion: This minimally invasive trans‐sphenoidal surgery for pituitary adenomas could be used as the primary treatment for small pituitary tumours. The effectiveness of the tumour removal and low morbidity rate compare favourably with the conventional sublabial approach as well as the more recently developed endoscopic endonasal approaches.     

Surgical outcomes of partial nephrectomy for renal cell carcinoma: A joint study by the Japanese Society of Renal Cancer

OBJECTIVE: A joint study was undertaken by the Japanese Society of Renal Cancer to investigate the present status of partial nephrectomy in Japan and to speculate about what may be the indications for partial nephrectomy in patients with renal cell carcinoma. METHODS: Data were tabulated for 469 patients from participating medical institutions and various clinical factors were investigated with regard to disease progression (local recurrence and distant metastasis). RESULTS: Disease progression was observed in 21 patients (4.5%). No significant relation to disease progression was observed for sex, laterality, tumor histology, grade and tumor size. Although patients with solitary tumors displayed excellent prognosis irrespective of tumor diameter, patients with multiple tumors displayed a high likelihood of disease progression. Patients older than 77 years old and patients with imperative indication were found to have a poorer prognosis. CONCLUSION: In patients with solitary tumors, partial nephrectomy can be actively performed, even if the patient displays elective indications and the tumor is >4 cm in diameter. In patients displaying multiple tumors with imperative indications, the decision whether to perform partial nephrectomy should be made by the patients and their physicians after considering the impact on curability and the quality of life.     

Open rhinoplasty for treatment of nasal tip haemangioma

Haemangiomas are the most common tumours of infancy. They typically proliferate then involute with considerable variation as regards to their rates of proliferation and involution. Haemangioma of the nasal tip is a lesion of special characteristics. During proliferation, it expands, contracts and deviates the nasal cartilages. Particularly, it regresses slowly and frequently involutes incompletely. That is why excision of the lesion is frequently suggested. The present study was conducted to evaluate open rhinoplasty after initial non-excision treatment modalities namely, intra-lesional corticosteroid injections and laser treatment, as a protocol of treatment for nasal tip haemangiomas. Twelve patients with nasal tip haemangiomas were included in the present study. Patients of both sexes, of different ages, with deep and mixed haemangiomas were studied. Disfigurement was the constant presenting symptom. Initial non-excision treatment reported different responses as denoted by the regression of the lesions’ size. Haemangiomas constantly extended between the medial crura of the alar cartilages as noted by the constant widening of the columella pre-operatively and the obvious separation of the nasal cartilages intra-operatively. This separation was constantly found to require approximation by sutures. The results of the present study concluded that whenever an early presentation with nasal tip haemangioma could be established, initial non-excision treatment followed by open rhinoplasty could be a useful protocol of treatment. Within the limitations of the present study, this protocol could achieve an early, safe and effective treatment for nasal tip haemangiomas with provisionally acceptable cosmetic outcomes so far.

25例垂体ACTH腺瘤的临床分析

目的分析和探讨垂体促肾上腺皮质激素(ACTH)腺瘤的临床特点和治疗方法。方法回顾性分析从2004年1月至2006年3月在我院接受治疗的25例垂体ACTH腺瘤患者的临床特点、治疗经过及预后。结果垂体ACTH腺瘤患者的临床症状和肿瘤的大小密切相关,微腺瘤(直径≤10 mm)患者以Cushing综合症征为主要临床表现,而大腺瘤(直径>10 mm)患者则以压迫症状为主。有无Cushing综合征的表现和腺瘤的直径呈负相关(P<0.05)。本组25例垂体ACTH腺瘤中21例具有侵袭性。垂体ACTH腺瘤患者主要以育后女性为主。该病首次经蝶手术后近期疗效显著。结论垂体ACTH大腺瘤以压迫症状为主,微腺瘤则以Cushing综合征表现为主。该肿瘤大多数具有侵袭性倾向,育后女性是高危人群。经蝶显微手术是垂体ACTH腺瘤的首选治疗方法。
