Chronic triceps insufficiency, causing prolonged disability, occurs due to a missed diagnosis of an acute rupture. We report a 25 year old male with history of a significant fall sustaining multiple injuries. Since then, he had inability in extending his right elbow for which he sought intervention after a year. Diagnosis of triceps rupture was made clinicoradiologically and surgery was planned. Intraoperative findings revealed a deficient triceps with a fleck of avulsed bone from olecranon. Ipsilateral double tendon graft including extensor carpi radialis longus and palmaris longus were anchored to triceps and secured with the olecranon. Six-months follow revealed a complete active extension of elbow and a full function at the donor site. 相似文献

A 38 year old man with previously normal electrocardiograms suffered a direct blow to the chest which resulted in electrocardiographic changes consistent with transient right bundle branch block. Serial enzyme determinations documented a rise in fraction 5 of serum lactic dehydrogenase. Evaluation subsequent to the injury were all within normal limits. An unexplained finding of paradoxical splitting of the pulmonic component of the second heart sound is noted. 相似文献

Evaluation of axillary lymphadenectomy without axillary drainage for patients undergoing breast-conserving therapy 总被引:3,自引:0,他引:3

Background: The routine use of drainage after axillary node dissection in patients undergoing breast-conserving therapy (BCT) is being questioned. To determine the value of routine drainage, we evaluated the postoperative course of patients with primary breast carcinoma who underwent axillary dissection with or without axillary drainage.
Methods: A retrospective review of 69 patients prompted a prospective randomized trial of 46 patients undergoing BCT at our tertiary cancer center. Variables studied were age, treatment (drain or no drain), number and tumor status of excised lymph nodes, size of primary tumor, duration of drainage or aspiration, number and volume of aspirations, number of office visits, incidence of complications and degree of pain, change in arm or forearm circumference, and body mass index (BMI). Data from prospective and retrospective studies were pooled for analysis.
Results: Of 115 patients, 72 were treated with a drain (Drain group) and 43 were not (No-drain group). Overall there was no difference in the number or tumor status of excised nodes, the size of the primary tumor, or the incidence of complications between the two groups. Aspiration was required in 50% of the No-drain patients and 8.3% of the Drain patients. The incidence of drain placement or replacement postoperatively was 9.3% for the No-drain patients and 4.2% for the Drain patients. The No-drain patients had more office visits (5.1±0.4 vs. 3.6±0.1;P=.0002) and a longer interval between operation and last aspiration or drain removal (16.2±1.4 days vs. 11.3±0.6 days;P=.0040). Findings were similar in the subgroup of 46 prospectively studied patients, who included 24 Drain patients and 22 No-drain patients. In this group, pain evaluation using a scale of 0 to 10 showed a mean rating of 4.2±2.6 in Drain patients and 2.7±0.4 in No-drain patients (P=.0062).
Conclusions: Axillary node dissection can be managed with or without a drain. More office visits but less pain can be expected if a drain is not used.Presented at the 50th Annual Cancer Symposium of The Society of Surgical Oncology, Chicago, IL, March 20–23, 1997.The views expressed herein are those of the authors and do not necessarily reflect the views of the United States Army, United States Navy, Uniformed Services University of the Health Sciences, or the Department of Defense. 相似文献

Over the past 7 years, eight patients with splanchnic artery aneurysms and pseudoaneurysms were studied and treated. Transcatheter embolization resulted in occlusion of the lesions in all eight patients. Potentially risky and difficult surgery was avoided completely in four patients. Three patients had elective surgery at a later date when their condition was more stable. The remaining patient had definitive surgery after embolization. Transcatheter embolization should be the initial treatment of choice in splanchnic artery aneurysms and pseudoaneurysms. 相似文献

Aim : The aim of this report is to review briefly the ontogeny of hematopoiesis in mice and humans and to discuss recent evidence for an intraembryonic source of hematopoietic stem cells. Methods : The hematopoiesis overview summarizes information present in the PubMed online database and from experiments conducted in our laboratories. Results : The major sites of hematopoiesis change throughout development in mice and humans. Recent evidence suggests that hematopoietic cells may emerge from mesoderm precursors within the embryo as well as in the yolk sac.
Conclusion : The ontogeny of hematopoiesis is similar in mice and humans. The murine system is a useful model to study the earliest events involved in forming hematopoietic stem cells. 相似文献
