Morbidity associated with anterior iliac crest bone graft
No full textObjective. The aim of this retrospective study was to assess the morbidity of the harvest of the anterior iliac bone graft and the overall satisfaction rates in a group of patients who underwent harvesting of iliac crest bone graft.Patients and Methods. Patients who underwent iliac crest bone graft procedures from January 2002 to August 2009 were recalled and invited to answer a questionnaire about postoperative pain, sensory disturbance, functional limitations, and cosmetic appearance.Results. A total of 61 patients were included in this retrospective study. Seventeen patients (28%) reported postoperative pain. A patient reported an intraoperative hip fracture. Sensory disturbances were reported by 3 patients.Conclusions. Anterior iliac crest can still be considered a favorable donor site for preprosthetic and cleft surgery. Given its relatively low morbidity rate, early ambulation, and hospital discharge, anterior iliac crest still remains the donor site of choice according to the authors.

Postoperative infections associated with microvascular free flaps in head and neck reconstruction: Analysis of risk factors and results with a standardized prophylaxis protocol
No full textCurrently, large defects of the head and neck regions are mainly reconstructed using microvascular free flap. Postoperative infections, including surgical site infections (SSIs) and medical postoperative infections (MPI), are important causes of morbidity and worsening of surgical outcomes. The authors aimed to analyze the results obtained using a standardized prophylaxis protocol in a series of 100 consecutive patients who underwent microvascular re- construction surgery between 2016 and 2021 at a single institution, to identify the risk factors, which could be overcome, to minimize the incidence of infectious complications. In this study, 24 patients developed infectious complications. Higher American Society of Anesthesiologists (ASA) score was statistically associated with higher risk of infectious com- plications (p = 0.01), need for postoperative transfusions (p = 0.01), and higher T and N stage (p = 0.03 and p = 0.02, respectively) in patients with cancer. We also found a correlation between the increase in surgery duration, hospitalization, and intensive care unit (ICU) stay with higher risk of infection (p = 0.03, p = 0.01, and p = 0.001, respectively). Nine patients reported partial or total flap necrosis and in this group of patients, a higher incidence of in- fectious complication was recorded (p = 0.001). Our experience shows that SSIs and MPIs affect the global and surgical outcomes of patients and both their incidences can be reduced by correcting potential risk factors preoperatively (e.g., anemia), intraoperatively (amount of blood loss and duration of surgery), and postoperatively (duration of hospitalization and ICU stay and early elimination of potential sources of infection).

Incidence of skeletal complications in patients with bone metastatic prostate cancer and hormone refractory disease: predictive role of bone resorption and formation markers evaluated at baseline.
No full textPURPOSE: We evaluated the incidence of skeletal complications in patients with bone metastatic prostate cancer and hormone refractory disease. We also assessed the predictive role of bone turnover markers determined at baseline. MATERIALS AND METHODS: A total of 112 patients were consecutively enrolled in our study from July 1990 to July 1998 and followed until death or the last followup. Bone pain, disease extent in bone, serum prostate specific antigen, hemoglobin, and a panel of bone formation and resorption markers were assessed at baseline before any second line treatment. RESULTS: Skeletal complications in 34 patients (30.3%, estimated yearly incidence 12.3%) involved vertebral deformity or collapse requiring spinal orthosis in 20 (17.9%), spinal cord compression in 7 (6.2%), pathological bone fracture in 10 (8.9%), symptomatic hypercalcemia in 1 (0.9%) and symptomatic hypocalcemia in 1 (0.9%). Median time to the evidence of the initial skeletal complication was 9.5 months. These adverse events did not influence overall survival. At baseline patients with eventual skeletal complications had greater bone pain (p = 0.02), a heavier tumor load in bone (p = 0.005), lower performance status (p = 0.05), and higher serum alkaline phosphatase (p <0.02) and urinary deoxypyridoline (p <0.05) than their counterparts. Multivariate analysis revealed that only urinary deoxypyridinoline was independently associated with the onset of these events (p <0.02). The scatterplot of urinary deoxypyridinoline values in patients with and without skeletal complications enabled us to detect a cutoff of 38 pM./mM. for predicting 51% of skeletal events with only an 8% false-positive rate. CONCLUSIONS: Skeletal complications are common in patients with prostate cancer and hormone refractory disease. Bone loss is the major cause of onset. Baseline deoxypyridinoline at the cutoff point noted had moderate sensitivity but high specificity for predicting these adverse skeletal events
Dispelling the Myths Behind First-author Citation Counts
No full textWe conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued
use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation
counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more
sophisticated methods

Standard vs. anatomical 180-W GreenLight laser photoselective vaporization of the prostate: a propensity score analysis.
No full textPURPOSE:
To compare the efficacy, safety, Patient Global Impression of Improvement (PGI-I), and complications rates after 180-W GreenLight laser (180-W GL laser) standard and anatomical photoselective vaporization (sPVP and aPVP).
METHODS:
Within a multi-institutional database, we identified patients who underwent sPVP or aPVP to relief BPH symptoms. IPSS, Q max, and prostate-specific antigen (PSA) were measured at baseline and during the follow-up. PGI-I score as well as early and late complications were recorded at follow-up visits. Log-binomial and multivariable proportional odds regression models were fitted to estimate the effect of aPVP vs. sPVP on PGI-I as well as on early and late complication rates, before and after adjustment for propensity score.
RESULTS:
813 patients were included. Of those, the 50.4% underwent aPVP. Patients who underwent aPVP had larger prostate (64 vs. 55 mL, p < 0.001) and higher baseline PSA levels (3.1 vs. 2.5 ng/mL, p < 0.001). PGI-I score was signaled as very improved, improved, slightly improved, unchanged, or worsened in 55.5, 32.8, 8.3, 2.3, and 1.2% of the cases, respectively, with no differences according the technique used (p = 0.420). Acute urinary retention occurred in 9.2 vs. 8.9% of patients after aPVP vs. sPVP (p = 0.872). All models failed to find differences in: patients' satisfaction (OR 1.19, p = 0.256), early complications (RR 0.93, p = 0.387), early urge/incontinence symptoms (RR 0.97, p = 0.814), and late complications rates (RR 0.70, p = 0.053), after aPVP vs. sPVP.
CONCLUSION:
Our results showed similar functional results and complication rates after aPVP and sPVP. However, aPVP was used in larger prostates. Both techniques guarantee high patient's satisfaction
The Right to Strike under the United States Constitution: Theory, Practice, and Possible Implications for Canada
No full textAnswering critics of the Canadian Supreme Court's judgment in B.C. Health, the author argues that the Court laid the foundation for a principled and durable doctrine protecting constitutional labour rights, one that goes directly to the heart of the matter — the inequality of workers’ power in the employment relation. In the author’s view, two paths could lead from B.C. Health to the recognition of Charter protec- tion for a right to strike: one that treats the right as an accessory to col- lective bargaining, and one that upholds the right directly on the basis of the Charter values of equality and participation. The author supports the latter approach, contending that constitutional rights should be defined in relation to fundamental values, in a way that is not contingent on time-bound or fact-sensitive assessments about the role of strikes within a particular collective bargaining regime. Although a Charter right to strike may involve the courts in difficult choices about when to defer to legislative policy decisions, and courts may lack the institutional capac- ity to deal effectively with labour law issues, the author points out that judges can look to ILO standards for expert guidance. Noting that the U.S. experience in this area might be of considerable use to Canadians, the author concludes by providing an overview of American case law concerning a constitutional right to strike.Peer reviewe
