Tachycardia is believed to be closely associated with hypotension and is often listed as an important sign in the initial diagnosis of hemorrhagic shock, but the correlation between heart rate and hypotension remains unproved. ⋯ Tachycardia is not a reliable sign of hypotension after trauma. Although tachycardia was independently associated with hypotension, its sensitivity and specificity limit its usefulness in the initial evaluation of trauma victims. Absence of tachycardia should not reassure the clinician about the absence of significant blood loss after trauma. Patients who are both hypotensive and tachycardic have an associated increased mortality and warrant careful evaluation.

Data on the relative clinical and economic impact of postoperative complications are needed in order to direct quality improvement efforts. ⋯ Complications are independently associated with increased resource use after high-risk surgery. Population-based studies may be valuable in determining the relative economic importance of postoperative complications. Quality improvement efforts for these complications should be prioritized based on both the incidence of the complication and its independent contribution to increased resource use.

Ideal tongue reconstruction after partial or total glossectomy should be accomplished with like tissue. The buccinator musculomucosal island flap is similar to lingual tissue, consisting of thin, pliable mucosa of mucus production, with high cell renewal rate and minimal scar formation, excellent color, contour, texture match, and buccinator muscle fibers over the flap's entire length, providing tongual muscle reconstruction without a conspicuous donor site. ⋯ The buccal musculomucosal island flap based on the facial artery and vein is a better reconstruction option with the same or similar kind of tissue as the tongue and, with the addition of the reinnervated flap, offers the potential for improved physiologic motion.

Surgical resection of primary colorectal cancer (CRC) in patients with stage IV disease at initial presentation remains controversial. Although bowel resection to manage symptoms such as bleeding, perforation, or obstruction has been advocated, management of asymptomatic patients has not been well defined. Patient-dependent factors (performance status, comorbid disease) and extent of distant metastases are among the considerations that impact on the decision to proceed with surgical management in asymptomatic stage IV CRC patients. We postulated that selected patients might benefit from elective resection of the asymptomatic primary CRC. The extent of distant metastases was objectively measured by several methods to identify potential prognostic variables that may help guide patient selection in this population. ⋯ Stage IV patients selected for elective palliative resection of asymptomatic primary colorectal cancers had substantial postoperative survival that was significantly better than those never having resection. Limited metastatic tumor burden and less extensive liver involvement were associated with better survival and a higher likelihood of benefit from elective bowel resection in asymptomatic patients with incurable stage IV CRC.
