RESUMO

BACKGROUND: The purpose of this investigation was to examine patients with low body mass index (BMI) regarding the feasibility to perform autologous breast reconstruction in such patients, as well as to determine optimal donor sites and evaluate outcomes accordingly. PATIENTS AND METHODS: All patients undergoing microsurgical breast reconstruction were divided into three cohorts based on BMI. Group 1 included patients with BMI greater than or equal to 22 kg/m(2) and was defined "low-normal BMI." Patients with BMI 22 to 25 kg/m(2) were placed in Group 2, labeled as "high-normal BMI." Group 3, defined as "overweight," included patients with BMI greater than 25 kg/m(2), but less than 30 kg/m(2). Patients were then analyzed based on demographics, breast cancer history, intraoperative details, complications, and revisionary surgeries. F-tests, chi-square goodness-of-fit tests, and Freeman-Halton extension of the Fisher exact tests were used for statistical analysis. RESULTS: During the study period, a total of 259 reconstructions were performed. Group 1 included 30 patients (n = 49 flaps), Group 2 included 58 patients (n = 98 flaps), and Group 3 included 69 patients (n = 112 flaps). Patients undergoing nipple-areolar sparing mastectomy were more likely to be in Groups 1 (39% [n = 19]) and 2 (37% [n = 37]) as compared with Group 3 (14.2% [n = 16]) (p < 0.001) as compared with the overweight cohort. Patients with increasing BMI were more likely to undergo abdominally based free flaps as compared with alternative donor sites (Group 1 = 2.26, Group 2 = 7.9, Group 3 = 27 [p < 0.001]). CONCLUSIONS: Abdominally based free flaps are possible in the majority of patients, however alternative harvest sites have to be used more frequently in low BMI patients.

RESUMO

BACKGROUND: The sheer number of accepted inferior turbinoplasty techniques emphasizes the fact that there is no general agreement on which approach yields optimal results, nor are there data available that describes prevalent techniques in turbinate surgery among plastic surgeons. OBJECTIVE: The aim of this study was to identify practice patterns among plastic surgeons who perform inferior turbinoplasty during rhinoplasty. METHODS: Members of the American Society of Plastic Surgeons were invited to participate in an anonymous, Internet-based survey containing questions related to personal preferences and outcomes in inferior turbinate surgery. RESULTS: A total of 534 members of the American Society of Plastic Surgeons participated in the survey. Most (71.7%) trained in an independent plastic surgery program with prerequisite training in general surgery. More than half (50.6%) had more than 20 years of operative experience; only 15.2% reported performing greater than 40 rhinoplasties per year. The 5 most preferred inferior turbinate reduction techniques were outfracture of the turbinates (49.1%), partial turbinectomy (33.3%), submucous reduction via electrocautery (25.3%), submucous resection (23.6%), and electrocautery (22.5%). Fewer than 10% of the respondents reported the use of newer techniques such as radiofrequency thermal ablation (5.6%), use of the microdebrider (2.2%), laser cautery (1.1%), or cryosurgery (0.6%). Mucosal crusting and desiccation were the most frequently reported complications. CONCLUSIONS: The results of this survey provide insights into the current preferences in inferior turbinate reduction surgery. Plastic surgeons are performing more conventional methods of turbinate reduction rather than taking advantage of the many of the more novel technology-driven methods.

RESUMO

Personality traits have been shown to interact with environmental cues to modulate biological responses including treatment responses, and potentially having a role in the formation of placebo effects. Here, we assessed psychological traits in 50 healthy controls as to their capacity to predict placebo analgesic effects, placebo-induced activation of µ-opioid neurotransmission and changes in cortisol plasma levels during a sustained experimental pain challenge (hypertonic saline infused in the masseter muscle) with and without placebo administration. Statistical analyses showed that an aggregate of scores from Ego-Resiliency, NEO Altruism, NEO Straightforwardness (positive predictors) and NEO Angry Hostility (negative predictor) scales accounted for 25% of the variance in placebo analgesic responses. Molecular imaging showed that subjects scoring above the median in a composite of those trait measures also presented greater placebo-induced activation of µ-opioid neurotransmission in the subgenual and dorsal anterior cingulate cortex (ACC), orbitofrontal cortex, insula, nucleus accumbens, amygdala and periaqueductal gray (PAG). Endogenous opioid release in the dorsal ACC and PAG was positively correlated with placebo-induced reductions in pain ratings. Significant reductions in cortisol levels were observed during placebo administration and were positively correlated with decreases in pain ratings, µ-opioid system activation in the dorsal ACC and PAG, and as a trend, negatively with NEO Angry Hostility scores. Our results show that personality traits explain a substantial proportion of the variance in placebo analgesic responses and are further associated with activations in endogenous opioid neurotransmission, and as a trend cortisol plasma levels. This initial data, if replicated in larger sample, suggest that simple trait measures easily deployable in the field could be utilized to reduce variability in clinical trials, but may also point to measures of individual resiliency in the face of aversive stimuli such as persistent pain and potentially other stressors.

RESUMO

BACKGROUND: Practitioners in other surgical specialties have increasingly advanced their volume of reconstructive procedures traditionally served by plastic surgeons. Because there has not been a previous specialty training comparison, the average operative reconstructive volume of graduating plastic surgery residents was formally compared with that of other specialties. METHODS: The authors review the case log statistical reports of the Accreditation Council for Graduate Medical Education. For each specialty, this annual report highlights the average number of cases performed for all graduating residents. The national case log reports were reviewed for orthopedic surgery, otolaryngology, and plastic surgery. Six procedures were compared for residents graduating in the 2006 to 2010 academic years and are reviewed. A two-sample Welch-Satterthwaite t test for independent samples with heterogeneous variance was conducted to compare the average number of procedures performed per graduating resident. RESULTS: Graduates of plastic surgery residencies compared with graduates of other specialties performed more cleft lip and palate repairs, hand amputation, hand fracture, and nasal fracture procedures. This difference showed statistical significance for all years examined (2006 to 2010). For repair of mandible fractures, plastic surgery trainees had significantly more cases for 2006 to 2009 but not 2010. CONCLUSIONS: The quantitative operative experience of graduating plastic surgery residents for selected reconstructive cases is above that of the average graduating trainee outside of plastic surgery. Given the exposure and strength of plastic surgery training, plastic surgeons should remain at the forefront of reconstructive surgery.

RESUMO

BACKGROUND: The great breadth of the specialty of plastic surgery is often misunderstood by practitioners in other specialties and by the public at large. The authors investigate the perceptions of primary care physicians in training toward the practice of different areas of plastic and reconstructive surgery. METHODS: A short, anonymous, Web-based survey was administered to residents of internal medicine, family medicine, and pediatrics training programs in the United States. Respondents were asked to choose the specialist they perceived to be an expert for six specific clinical areas, including eyelid surgery, cleft lip and palate surgery, facial fractures, hand surgery, rhinoplasty, and skin cancer of the face. Specialists for selection included the following choices: dermatologist, general surgeon, ophthalmologist, oral and maxillofacial surgeon, orthopedic surgeon, otolaryngologist, and plastic surgeon. RESULTS: A total of 1020 usable survey responses were collected. Respondents believed the following specialists were experts for eyelid surgery (plastic surgeon, 70 percent; ophthalmologist, 59 percent; oral and maxillofacial surgeon, 15 percent; dermatologist, 5 percent; and otolaryngologist, 5 percent); cleft lip and palate surgery (oral and maxillofacial surgeon, 78 percent; plastic surgeon, 57 percent; and otolaryngologist, 36 percent); facial fractures (oral and maxillofacial surgeon, 88 percent; plastic surgeon, 36 percent; otolaryngologist, 30 percent; orthopedic surgeon, 11 percent; general surgeon, 3 percent; and ophthalmologist, 2 percent); hand surgery (orthopedic surgeon, 76 percent; plastic surgeon, 52 percent; and general surgeon, 7 percent); rhinoplasty (plastic surgeon, 76 percent; otolaryngologist, 45 percent; and oral and maxillofacial surgeon, 18 percent); and skin cancer of the face (dermatologist, 89 percent; plastic surgeon, 35 percent; oral and maxillofacial surgeon, 9 percent; otolaryngologist, 8 percent; and general surgeon, 7 percent). CONCLUSION: As the field of plastic surgery and other areas of medicine continue to evolve, additional education of internal medicine, pediatrics, and family practice physicians and trainees in the scope of plastic surgery practice will be critical.
