RESUMO
Simultaneous bilateral quadriceps tendon ruptures are a rare occurrence commonly associated with a traumatic event or systemic disease. A 31-year-old man presented with simultaneous bilateral quadriceps tendon ruptures with associated hyperparathyroidism secondary to parathyroid carcinoma. The injury occurred after the patient attempted to lift a small wooden log from the ground. We discussed the multidisciplinary management of this patient resulting in bilateral quadriceps tendon repairs, tumor resection, and oncological and endocrinological restoration. Clinical follow-up is reported at 15 years after surgery. Parathyroid carcinoma is an extremely rare cancer and rarely the cause of hyperparathyroidism. The systemic effects of the tumor eventually lead to the rupturing of both quadriceps tendons. Orthopaedic physicians must remain vigilant in identifying the root cause of injuries that are atypical in nature.

Cardiovascular disease is the most prevalent and influential comorbidity affecting outcomes in geriatric surgical patients. The unique physiology of the aging cardiovascular system and the impact of these changes during the stress of surgery is presented in this article. The necessary response to these changes is discussed with attention to methods of monitoring and recommendations for providing supportive care.

Venous thromboembolism (VTE) is a leading cause of death in multisystem trauma patients; the importance of VTE prevention is well recognized. Presently, standard dose enoxaparin (30 mg BID) is used as chemical prophylaxis, regardless of weight or physiologic status. However, evidence suggests decreased bioavailability of enoxaparin in critically ill patients. Therefore, we hypothesized that a weight-based enoxaparin dosing regimen would provide more adequate prophylaxis (as indicated by antifactor Xa levels) for patients in our trauma intensive care unit (TICU).These data were prospectively collected in TICU patients admitted over a 5-month period given twice daily 0.6 mg/kg enoxaparin (actual body weight). Patients were compared with a historical cohort receiving standard dosing. Anti-Xa levels were collected at 11.5 hours (trough, goal ≥ 0.1 IU/mL) after each evening administration. Patient demographics, admission weight, dose, and daily anti-Xa levels were recorded. Patients with renal insufficiency or brain, spine, or spinal cord injury were excluded. Data were collected from 26 patients in the standard-dose group and 37 in the weight-based group. Sixty-four trough anti-Xa measurements were taken in the standard dose group and 74 collected in the weight-based group. Evaluating only levels measured after the third dose, the change in dosing of enoxaparin from 30 to 0.6 mg/kg resulted in an increased percentage of patients with goal antifactor Xa levels from 8 per cent to 61 per cent (P < 0.0001). Examining all troughs, the change in dose resulted in an increase in patients with a goal anti-Xa level from 19 to 59 per cent (P < 0.0001). Weight-based dosing of enoxaparin in trauma ICU patients yields superior results with respect to adequate anti-Xa levels when compared with standard dosing. These findings suggest that weight-based dosing may provide superior VTE prophylaxis in TICU patients. Evaluation of the effects of this dosing paradigm on actual VTE rate is ongoing at our institution.

BACKGROUND: This study evaluates the efficacy of negative-pressure therapy (NPT) in preventing surgical site infections (SSIs) in high-risk surgical oncology patients. METHODS: A retrospective analysis of 191 operations for colorectal, pancreatic, or peritoneal surface malignancies was performed. Incisional NPT was used in patients with multiple SSI risk factors. Rates of SSIs were compared with patients treated with a standard sterile dressing (SSD). RESULTS: NPT was used in 104 patients, whereas SSDs were used in 87 patients. Despite being at an increased risk of SSI, patients treated with NPT developed fewer superficial incisional SSIs compared with SSD patients (6.7% vs 19.5%, P = .015). In a subgroup analysis of clean-contaminated cases, NPT was associated with fewer superficial incisional SSIs (6.0% vs 27.4%, P = .001), fewer total SSIs (16.0% vs 35.5%, P = .011), and fewer wound openings for any reason (16.0% vs 35.5%, P = .011). CONCLUSIONS: Our findings suggest that NPT decreases SSIs in high-risk surgical oncology patients.

BACKGROUND: Recent studies have identified unique clinical and physiologic characteristics of emergency general surgery (EGS) patients and called for outcomes data in this population. There are no data in the US literature analyzing the impact of technique on anastomotic failure rates in EGS patients. The purpose of the current study was to compare outcomes of hand-sewn (HS) versus stapled (ST) bowel anastomoses in EGS patients. METHODS: A retrospective chart review of all patients admitted by our EGS service undergoing bowel resection for emergent indications from January 2007 to July 2011 was performed. Time from surgery to diagnosis of anastomotic failure was recorded as were the diagnostic modality and treatment of each anastomotic failure. Specific data on damage-control techniques, if used, were also collected. RESULTS: There were 100 HS (43%), and 133 ST (57%) anastomoses in 231 patients. Operative times were shorter in ST anastomosis technique (205 minutes for HS vs. 193 minutes for ST, p = 0.02). Anastomotic failures were identified in 26 patients (11%) and were significantly higher in the ST group than the HS group (15.0% vs. 6.1%, p = 0.003). A multivariate logistic regression analysis, controlling for age and preoperative nutritional status, revealed ST technique to be an independent risk factor for anastomotic failure (odds ratio, 2.65; 95% confidence interval, 1.08-6.50; p = 0.034). CONCLUSION: Anastomotic failures are more than twice as likely with ST than HS anastomoses in the EGS population. This is true even when controlling for markers of preoperative nutrition and demographics. These data suggest that the HS anastomosis should be the preferred method of reconstruction after bowel resection in EGS patients.
