Interscapulothoracic (forequarter) amputation for malignant tumors involving the upper extremity: surgical technique and case series.

BACKGROUND: Forequarter amputation (FQA) is reserved for large, multifocal, or recurrent tumors affecting the shoulder and upper extremity. Although it is performed less frequently with the advancement of limb salvage surgery, FQA remains an important treatment in select patients. The purpose of this study is to illustrate the surgical technique in a case series of 4 patients. METHODS: Between 2010 and 2012, 4 patients (mean age, 61 years; range, 36-78 years) presented with malignant disease of the upper extremity that was not amenable to or had failed limb salvage. All patients had FQA by the illustrated anterior clavicular osteotomy technique. Patient data were retrospectively reviewed from preoperative workup until last follow-up or death. RESULTS: All patients had tumors that involved major neurovascular structures of the upper extremity and shoulder girdle. One presented with neuroendocrine carcinoma and has achieved local control after FQA. Three presented with high-grade sarcoma. One of these had recurrence after prior limb salvage and neoadjuvant radiation and unfortunately succumbed to metastatic disease 6 months after FQA. An additional sarcoma patient who presented after shoulder arthroscopy for a "labral cyst" with recurrent and fulminant synovial sarcoma succumbed to her disease. The remaining sarcoma patient has had no recurrence and minimal phantom pain at last follow-up. DISCUSSION: Obtaining vascular control early in the procedure is crucial to minimize blood loss. When it is indicated, FQA is a relatively safe and reliable procedure for dealing with otherwise challenging tumors of the shoulder girdle and upper extremity. LEVEL OF EVIDENCE: Level IV, case series, treatment study.

Risk stratified usage of antibiotic-loaded bone cement for primary total knee arthroplasty: short term infection outcomes with a standardized cement protocol.

Efficacy of antibiotic cement (ALBC) in primary knee arthroplasty (pTKA) has been debated. The study's purpose was to examine efficacy of ALBC versus plain cement (PBC) in preventing infection in high-risk patients undergoing pTKA. 3292 consecutive pTKAs were divided into three cohorts: (1) patients receiving only PBC, (2) patients receiving only ALBC, and (3) only high-risk patients receiving ALBC. Cohorts' infections were compared. The 30-day infection rates for cohorts 1, 2, 3 were 0.29%, 0.20%, and 0.13% respectively. 6-month rates were 0.39%, 0.54% and 0.38%. 1-year rates were 0.78%, 0.61%, and 0.64%. Differences in infection rates at all time intervals were not statistically significant. The study supports that even judicious risk-stratified usage of ALBC may not confer added benefit in decreasing infection at one year.

The prevalence and nutritional implications of fast food consumption among patients receiving hemodialysis.

BACKGROUND: Fast food consumption has increased dramatically in the general population over the last 25 years. However, little is known about the prevalence and nutritional implications of fast food consumption among patients receiving hemodialysis. METHODS: By using a cross-sectional study design, we obtained data on fast food consumption and nutrient intake (from four separate 24-hour dietary recalls) and nutritional parameters (from chart abstraction) for 194 randomly selected patients from 44 hemodialysis facilities in northeast Ohio. RESULTS: Eighty-one subjects (42%) reported consuming at least one fast food meal or snack in 4 days. Subjects who consumed more fast food had higher kilocalorie, carbohydrate, total fat, saturated fat, and sodium intakes. For example, kilocalorie per kilogram intake per day increased from 18.9 to 26.1 with higher frequencies of fast food consumption (P = .003). Subjects who consumed more fast food also had higher serum phosphorus levels and interdialytic weight gains. CONCLUSION: Fast food is commonly consumed by patients receiving hemodialysis and is associated with a higher intake of kilocalories, carbohydrates, fats, and sodium and adverse changes in phosphorus and fluid balance. Further work is needed to understand the long-term benefits and risks of fast food consumption among patients receiving hemodialysis.
