RESUMO
BACKGROUND: Chordomas are rare, slow-growing, locally aggressive, malignant tumors of the spine. Chordomas are conventionally treated with surgical resection with or without radiation. There is an absence of literature documenting the natural history of a primary sacral chordoma. CASE DESCRIPTION: A 65-year-old man presented with rectal pain, constipation, urinary and fecal incontinence, S1 radiculopathy, and a palpable rectal mass. A needle biopsy confirmed the pathologic diagnosis of sacral chordoma. The patient declined to have surgery because of the surgical risks involved. He was managed conservatively with supportive care only. The patient was routinely followed in clinic and had a subjective and objective excellent quality of life with adequate pain management. Meanwhile, his neurologic status did not deteriorate. During follow-up, some posterolateral aspects of the chordoma regressed. However, the bulk of the lesion continued to slowly progress. The patient survived for 7.5 years. He eventually succumbed to urosepsis and new-onset peritoneal metastasis. CONCLUSIONS: To our knowledge, the patient is the only documented case in the literature of an untreated biopsy-proven sacral chordoma. The patient's tumor was intended for resection, and therefore comparable with data from treated chordomas. The patient's survival is similar to the median survival in treated chordomas. The patient's survival was despite negative prognosticators, such as advanced age of the patient and high sacral location above S2.

INTRODUCTION: Optimal enoxaparin dosing for deep venous thrombosis (DVT) prophylaxis remains elusive. Prior research demonstrated that trauma patients at increased risk for DVT based upon Greenfield's risk assessment profile (RAP) have DVT rates of 10.8% despite prophylaxis. The aim of this study was to determine if goal directed prophylactic enoxaparin dosing to achieve anti-Xa levels of 0.3-0.5IU/ml would decrease DVT rates without increased complications. MATERIALS AND METHODS: Retrospective review of trauma patients having received prophylactic enoxaparin and appropriately timed anti-Xa levels was performed. Dosage was adjusted to maintain an anti-Xa level of 0.3-0.5IU/ml. RAP was determined on each patient. A score of ≥5 was considered high risk for DVT. Sub-analysis was performed on patients who received duplex examinations subsequent to initiation of enoxaparin therapy to determine the incidence of DVT. RESULTS: 306 patients met inclusion criteria. Goal anti-Xa levels were met initially in only 46% of patients despite dosing of >40mg twice daily in 81% of patients; however, with titration, goal anti-Xa levels were achieved in an additional 109 patients (36%). An average enoxaparin dosage of 0.55mg/kg twice daily was required for adequacy. Bleeding complications were identified in five patients (1.6%) with three requiring intervention. There were no documented episodes of HIT. Subsequent duplex data was available in 197 patients with 90% having a RAP score >5. Overall, five DVTs (2.5%) were identified and all occurred in the high-risk group. All patients were asymptomatic at the time of diagnosis. CONCLUSION: An increased anti-Xa range of 0.3-0.5IU/ml was attainable but frequently required titration of enoxaparin dosage. This produced a lower rate of DVT than previously published without increased complications.

A 24 year old male arrived to our hospital after a motor cycle crash with evidence of a traumatic brain injury and in hemorrhagic shock not responsive to volume administration. Resuscitative Endovascular Balloon Occlusion of the Aorta (REBOA) was performed in a timely fashion using a new, low profile, wire free device. This lead to rapid reversal of hypotension while his bleeding source was sought and controlled. Recently, REBOA has emerged as an adjunct in the hypotensive trauma patient with noncompressible torso hemorrhage. As first described, this procedure makes use of commonly available vascular surgery and endovascular products requiring large introducer sheaths (12-14 French) and long guidewires. Concerns regarding this technique center around the safety and feasibility of using such equipment in the emergency setting outside an angiography suite. This has likely limited widespread adoption of this technique. To address these concerns, newer products designed to be placed through a smaller sheath (7 French) and without the use of guidewires have been developed. Here we report on our first clinical use of such a device that we believe represents a significant advance in the care of the trauma patient.
RESUMO
BACKGROUND: Computed tomography (CT) has been validated to identify and classify placental abruption following blunt trauma. The purpose of this study was to demonstrate improvement in fetal survival when delivery occurs by protocol at the first sign of class III fetal heart rate tracing in pregnant trauma patients with a viable fetus on arrival and CT evidence of placental perfusion 50% or less secondary to placental abruption. METHODS: This is a retrospective review of pregnant trauma patients at 26 weeks' gestation or greater who underwent abdominopelvic CT as part of their initial evaluation. Charts were reviewed for CT interpretation of placental pathology with classification of placental abruption based upon enhancement (Grade 1, >50% perfusion; Grade 2, 25%-50% perfusion; Grade 3, <25% perfusion), as well as need for delivery and fetal outcomes. RESULTS: Forty-one patients met inclusion criteria. Computed tomography revealed evidence of placental abruption in six patients (15%): Grade 1, one patient, Grade 2, one patient, and Grade 3, four patients. Gestational ages ranged from 26 to 39 weeks. All patients with placental abruption of Grade 2 or greater developed concerning fetal heart tracings and underwent delivery emergently at first sign. Abruption was confirmed intraoperatively in all cases. Each birth was viable, and Apgar scores at 10 minutes were greater than 7 in 80% of infants, all of whom were ultimately discharged home. The remaining infant was transferred to an outside facility. CONCLUSIONS: Delivery at first sign of nonreassuring fetal heart rate tracings in pregnant trauma patients (third trimester) with placental abruption of Grade 2 or greater can lead to improved fetal outcome. LEVEL OF EVIDENCE: Therapeutic/care management study, level III.

Positive margins occur in 15 to 69 per cent of patients undergoing lumpectomy. The current study was performed to evaluate intraoperative ultrasound in patients undergoing lumpectomy for palpable breast cancer. A retrospective chart review was performed of patients with palpable cancer who underwent lumpectomy with intraoperative ultrasound from 2004 to 2009. Each patient was matched with two patients who underwent lumpectomy alone over the same time period. Matching criteria included tumor size, clinical stage, body mass index, age at diagnosis, and lymphovascular invasion or extensive intraductal component. Twenty-two consecutive patients who underwent lumpectomy with intraoperative ultrasound were matched with 44 patients who underwent lumpectomy without intraoperative ultrasound. In addition to matching criteria, the patients were similar with respect to ethnicity, insurance status, weight, predominant histology, estrogen receptor, progesterone receptor, and Her2 status. Patients who underwent lumpectomy with intraoperative ultrasound were significantly less likely to have an involved margin (41 vs 9%, P = 0.01) and less likely to require a re-excision (34 vs 9%, P = 0.04). The lumpectomy volumes in the intraoperative ultrasound group were smaller than the volumes in the lumpectomy alone group. Intraoperative ultrasound can decrease the rate of positive margins and re-excision lumpectomy in patients with palpable breast cancers.

Immediate reconstruction has demonstrated superior cosmesis compared with delayed reconstruction, however, unexpected final pathology may necessitate post mastectomy radiation. We describe an alternative technique for immediate breast reconstruction. Twelve patients underwent 14 skin-sparing mastectomies from July 2006 to December 2009. The skin-sparing mastectomies and sentinel node biopsies were performed through a periareolar incision. At the completion of the operation the incision was closed in a transverse fashion. No simultaneous reconstruction was performed. No drains were placed. After 3 days seroma developed, which maintained the integrity of the skin envelope and appearance of a breast. Nine patients (75%) had a contraindication to breast conservation. All patients were clinically node negative and 67 per cent were clinical stage 0. The majority (75%) experienced an adverse change from clinical stage to final pathologic stage. Four patients (33%) required postmastectomy radiation. The mean time from oncologic procedure to initial reconstruction procedure was 14 days. Two patients (17%) developed postoperative infections. This technique allows immediate reconstruction and avoids the fear of adverse final pathology indicating radiation to the reconstructed breast. In addition, it provides flexibility in scheduling for the surgeons and allows the patient to maintain the appearance of the breast.
