Effects of Breast Surgery on Interoceptive Awareness in Females.

Background: The driving force for many seeking plastic surgery is comfort in one's body. Along with comfort come satisfaction, improved self-awareness, and potential change in interoceptive awareness-a term defined as the conscious perception of one's body. Although conscious perception of bodily signals is influenced by many factors, sense of self and body image play significant roles. Studies show diminished interoceptive awareness in those with negative body image, but no research has assessed the impact of change in body image on interoceptive awareness. Objectives: The purpose of this study is to investigate how interoceptive awareness changes following elective breast surgery. Methods: The Multidimensional Assessment of Interoceptive Awareness Version 2 (MAIA-2) was administered to females undergoing breast surgery. A baseline survey was administered preoperatively, with follow-up surveys at 1 week, 1 month, and 3 months postoperatively. Results: Data were collected from 39 females and analyzed using paired t-tests to compare MAIA-2 overall and subscores over time. Significance was seen at 1 week for subcategories of "not distracting" and "trust," at 1 month for "trust," and 3 months for "not worrying," "emotional awareness," "self-regulation," and "trust." Overall survey averages were significantly increased at all postoperative intervals. Conclusions: From this study, it can be concluded that breast surgery positively impacts interoceptive awareness. These findings are clinically relevant as they offer providers' insight into the psychological effects of breast procedures. A comprehensive understanding of procedure outcomes enables providers to educate patients on both anticipated physical results and changes in sense of self.

Outcomes of Negative Pressure Wound Therapy on Immediate Breast Reconstruction after Mastectomy.

Immediate expander/implant-based breast reconstruction after mastectomy has become more sought after by patients. Although many patients choose this technique due to good aesthetic outcomes, lack of donor site morbidity, and shorter procedure times, it is not without complications. The most reported complications include seroma, infection, hematoma, mastectomy flap necrosis, wound dehiscence, and implant exposure, with an overall complication rate as high as 45%. Closed incision negative pressure therapy (ciNPT) has shown value in wound healing and reducing complications; however, the current literature is inconclusive. We aimed to examine if ciNPT improves outcomes for patients receiving this implant-based reconstruction. Methods: This is a retrospective single-institution study evaluating the ciNPT device, 3M Prevena Restor BellaForm, on breast reconstruction patients. The study was performed between July 1, 2019 and October 30, 2020, with 125 patients (232 breasts). Seventy-seven patients (142 breasts) did not receive the ciNPT dressing, and 48 patients (90 breasts) received the ciNPT dressing. Primary outcomes were categorized by major or minor complications. Age, BMI, and final drain removal were summarized using medians and quartiles, and were compared with nonparametric Mann-Whitney test. Categorical variables were compared using chi-square or Fisher exact test. Results: There was a statistically significant reduction in major complications in the ciNPT group versus the standard dressing group (P = 0.0247). Drain removal time was higher in the ciNPT group. Conclusion: Our study shows that ciNPT may help reduce major complication rates in implant-based breast reconstruction patients.

No Opioids after Septorhinoplasty: A Multimodal Analgesic Protocol.

From a public health perspective, nasal surgery accounts for many unused opioids. Patients undergoing septorhinoplasty require few opioids, and efforts to eliminate this need may benefit both patients and the public. METHODS: A multimodal analgesic protocol consisting of 15 components encompassing all phases of care was implemented for 42 patients. RESULTS: Median age and BMI were 34 years and 23, respectively. Most were women (79%), White (79%), primary surgeries (62%), and self-pay (52%). Comorbid conditions were present in 74% of the patients, with anxiety (33%) and depression (21%) being the most common. Septoplasties (67%) and osteotomies (45%) were common. The median operative time was 70 minutes. No patients required opioids in recovery, and median time in recovery was 63 minutes. Ten (24%) patients required an opioid prescription after discharge. In those patients, median time to requirement was 27 hours (range 3-81), and median total requirement was 20 mg morphine equivalents (range 7.5-85). Protocol compliance inversely correlated to opioid use (P = 0.007). Compliance with local and regional anesthetic (20% versus 63%, P = 0.030) as well as ketorolac (70% versus 100%, P = 0.011) was lower in patients who required opioids. Patients who required opioids were less likely to be administered a beta blocker (0% versus 34%, P = 0.041). Pain scores were higher in opioid users on postoperative days 1-5 (P < 0.05). No complications occurred in those requiring opioids, and satisfaction rates were equivalent between groups. CONCLUSION: This protocol allowed us to safely omit opioid prescriptions in 76% of patients following septorhinoplasty, without adverse effects on outcomes or patient satisfaction.

Acute symptomatic hyponatremia following elective rhinoplasty: A case report.

We present the first reported case of symptomatic hyponatremia after elective rhinoplasty. A 42-year old female underwent cosmetic rhinoplasty without complication and was discharged home after an uneventful recovery from general anesthesia. Just prior to midnight on the day of surgery, she reported nausea, which was treated with supportive care. Four hours later, she developed emesis, altered mental status, and seizure-like activity prompting medical transport to the emergency department. Upon arrival, she was hypotensive (BP 78/54), tachycardic (HR 112 bpm), hyponatremic (116 mmol/L), hypoosmotic (239 mOsm/kg), and had decreased consciousness (GCS = 10). She was admitted to the intensive care unit and had a central line placed for hypertonic saline infusion. Urinalysis was suggestive of SIADH (UrNa 111 mmol/L, UrOsm 546 mOsm/kg) and Nephrology was consulted. Her serum sodium was corrected over three days and her mental status improved. Surgeons should maintain a low threshold for further evaluation in patients who deviate from the expected postoperative recovery pathway. This report demonstrates that normal postoperative symptoms may mask underlying physiological abnormalities that can progress to acute life-threatening illness and underscores the importance of direct patient observation in the immediate postoperative period.

Salmonella infection of breast implant associated with traveler's diarrhea: A case report.

We present the first case of traveler's diarrhea resulting in breast implant infection. An otherwise healthy 34-year-old female underwent breast augmentation. Five months later, while vacationing in Cancun, Mexico, she developed abdominal pain and diarrhea that progressed to include fevers and chills. Her symptoms persisted until she returned to the United States, at which point her primary care physician evaluated her on the fourth day of her illness. An abdominal CT scan was unremarkable; however, a complete metabolic panel demonstrated elevated transaminases. Her symptoms soon resolved without treatment. Fourteen days after symptom resolution, the patient developed right breast pain. She was evaluated in the surgical clinic where the breast was tender to palpation, swollen and without erythema. An ultrasound demonstrated a small amount of homogenous fluid surrounding the implant. She was prescribed amoxicillin-clavulanate 875-125 mg BID; however, she presented three days later with worsening pain, swelling and new erythema. She was taken to the operating room, where the abscess was incised, drained and the implant removed. Cultures grew Salmonella serogroup C. Patients should be counseled regarding the potential for hematogenous seeding of the breast cavity and implant following severe illness and bacteremia. It may be reasonable to provide patients with breast implants who are traveling to areas at high-risk for traveler's diarrhea or areas with limited medical resources with an antibiotic to take if moderate to severe symptoms of traveler's diarrhea were to develop while away.

Comparison of miniplates and reconstruction plates in fibular flap reconstruction of the mandible.

BACKGROUND: Mandibular reconstruction using free fibular flaps can be performed using various plating techniques. Miniplates (2.0 mm) have different characteristics that provide theoretical advantages and disadvantages with regard to successful neomandibular fixation. METHODS: A retrospective review of 117 patients undergoing free fibular reconstruction of segmental mandibular defects over the past 10 years was performed. Characteristic data and complication rates were recorded; the authors compared patients who had fibular reconstruction of their mandibular defect with miniplates (n = 86) with those who underwent repair using reconstruction plates (n = 31). RESULTS: No statistically significant difference was identified when comparing miniplates and reconstruction plates with regard to overall cumulative complication rates (46 versus 48 percent), flap failure (15 percent versus 27 percent), plate extrusion (23 percent versus 25 percent), malunion or nonunion (14 percent versus 13 percent), and plate fracture (10 percent versus 0 percent). (The cumulative percentage incidence weighs patient data according to length of follow-up.) The authors' data did suggest a decreased incidence of osteonecrosis in the miniplate group (5 percent versus 38 percent; p = 0.02), but these results must be interpreted cautiously because of the small sample size. CONCLUSION: Selection of plate size, miniplate versus reconstruction plate, does not appear to affect the overall rate of complications in free fibular reconstruction of the mandible.

Concomitant arterial and venous reconstruction with resection of lower extremity sarcomas.

INTRODUCTION: Limb salvage can now be achieved in many cases of lower extremity sarcoma. Obtaining disease-free margins may require resection of adjacent vascular structures. We present our experience with a consecutive series of patients undergoing resection of lower extremity sarcomas en block with the artery and vein, focusing on the mid- and long-term outcomes of their vascular reconstruction. METHODS: Records were reviewed retrospectively for patient age, tumor location and type, procedure, and early and late outcomes. Between 1991 and 2004, 10 children (mean age 12 years, range 6-18 years) and 9 adults (mean age 48 years, range 24-73 years) underwent wide resection of lower extremity sarcomas to include the involved arterial and venous segments. All children had bone sarcomas, and because of their skeletal immaturity, they were treated with rotationplasty--a type of intercalary amputation that removes the distal thigh, knee, and proximal tibia while preserving the distal leg and foot. In rotationplasty, the distal residual limb is preserved, rotated 180 degrees, and attached to the thigh, positioning the ankle at the level of the former knee joint. In these cases, the residual vessels were reconstructed by primary anastomosis. All of the adults except one had soft tissue sarcomas; the resected vessels were reconstructed with contralateral saphenous vein. In all cases, the operative approach included shunting of artery and vein during tumor removal and orthopedic reconstruction. RESULTS: The mean follow-up was 5.7 years. Three patients died of metastatic disease, and one died from a postoperative pulmonary embolism. No patient had local recurrence. Two patients ultimately required above-knee amputation: one child for tissue loss secondary to reperfusion injury, and one adult because of graft thrombosis secondary to progression of peripheral arterial disease. Two patients required early re-exploration for perioperative graft thrombosis. Both required replacement of saphenous vein conduits with polytetrafluoroethylene (PTFE) prosthetic graft; one of the PTFE grafts became infected. CONCLUSIONS: Limb salvage can be achieved in the majority of patients who have lower extremity sarcomas even when en bloc resection includes the artery and vein. Intraoperative shunting can limit ischemia and is especially useful when immediate vascular repair is delayed by orthopedic reconstruction. The long-term patency rate of the reconstructed vessels is high. Saphenous vein is the preferred conduit when it is of adequate caliber.

Relative imbalances in the expression of estrogen-metabolizing enzymes in the breast tissue of women with breast carcinoma.

Estrogens are a known risk factor for breast cancer. Studies indicate that initiation of breast cancer may occur by metabolism of estrogens to form abnormally high levels of catechol estrogen-3,4-quinones, which can then react with DNA to form depurinating adducts and, subsequently, induce mutations that lead to cancer. Among the key enzymes metabolizing estrogens are two activating enzymes: cytochrome P450 (CYP)19 (aromatase), which converts androgens to estrogens, and CYP1B1, which converts estrogens predominantly to the 4-catechol estrogens that are further oxidized to catechol estrogen-3,4-quinones. Formation of the quinones is prevented by methylation of the 4-catechol estrogens by the enzyme, catechol-O-methyltransferase (COMT). In addition, catechol estrogen quinones can be reduced back to catechol estrogens by NADPH quinone oxidoreductase 1 (NQO1) and/or are coupled with glutathione, preventing reaction with DNA. Thus, COMT and NQO1 are key deactivating enzymes. In this initial study, we examined whether the expression of these four critical estrogen activating/deactivating enzymes is altered in breast cancer. Control breast tissue was obtained from four women who underwent reduction mammoplasty. Breast tissues from five women with breast carcinoma, who underwent mastectomy, were used as cases. The level of expression of CYP19, CYP1B1, COMT and NQO1 mRNAs was quantified from total RNA using a real time RT-PCR method in an ABI PRISM 7700 sequence detection system. The control breast tissues showed lower expression of the activating enzymes, CYP19 and CYP1B1, and higher expression of the deactivating enzymes, COMT and NQO1, compared to the cases. In the cases, the reverse pattern was observed: greater expression of activating enzymes and lower expression of deactivating enzymes. Thus, in women with breast cancer, estrogen metabolism may be related to altered expression of multiple genes. These unbalances appear to be instrumental in causing excessive formation of catechol estrogen quinones that, by reacting with DNA, initiate the series of events leading to breast cancer.

The use of full-thickness skin grafts for the skin-abutment interface around bone-anchored hearing aids.

OBJECTIVE: To review the complication rate encountered with the use of full-thickness skin grafts to establish the skin-abutment interface around bone-anchored hearing aid implants. STUDY DESIGN: Retrospective chart review. SETTING: Tertiary referral center. PATIENTS: Fifteen patients who underwent bone-anchored hearing aid placement over a 4-year period. INTERVENTION: Each percutaneous titanium implant and abutment was placed into the temporal bone following the standard Branemark technique. Eight procedures were performed in two stages, and seven were performed as single-stage procedures. In all cases, the skin-abutment interface was established by use of a full-thickness skin graft inset around the implant. MAIN OUTCOME MEASURES: The incidence of complications resulting in skin graft loss, time from implantation to bone-anchored hearing aid use, additional procedures for revision of the interface, and complicating medical factors in the patient population. RESULTS: Seven patients (46.7%) experienced loss of the full-thickness skin graft around the abutment. Four of these seven had complicating medical factors associated with impaired wound healing: two with diabetes mellitus, one of whom was also a smoker, and two patients who were receiving inhaled steroids for treatment of asthma. Of the seven patients who lost skin grafts, two healed by secondary intention, two underwent repeated full-thickness skin grafting, and three underwent galeal rotation flaps with split-thickness skin grafting, one of which eventually required a scalp flap. No patient experienced loss of the implant. CONCLUSION: The use of full-thickness skin grafts for establishment of the skin-abutment interface around bone-anchored hearing aid implants is associated with a high rate of graft loss. Although salvage techniques can successfully establish the interface after skin graft failure, alternative methods should be considered, especially in high-risk patients.
