Patient Satisfaction Using BREAST-Q and Breast Implant Illness after Breast Reconstruction in Transwomen.

Background: Gender-affirming breast augmentation comprises an increasing portion of breast augmentations performed by plastic surgeons. Satisfaction and breast implant illness (BII) symptoms in this population have not been well studied. This study aimed to evaluate satisfaction and BII symptoms in transwomen who received nontextured implants as part of their breast reconstruction. Methods: We conducted a retrospective review of transwomen who underwent breast augmentation for gender-affirming surgery. We performed telephone survey evaluation using the BREAST-Q questionnaire preoperatively, 6 months and 1 year after breast implant placement. Survey evaluation asking about BII symptoms was also administered at the same time points. Results: Twenty-six patients completed the BREAST-Q survey, which demonstrated significantly improved satisfaction postoperatively at 6 and 12 months when compared with median preoperative scores for psychosocial (P < 0.001; P < 0.001), sexual (P < 0.001; P < 0.001), and overall satisfaction with breasts (P < 0.001; P < 0.001). Physical well-being of the chest decreased at 6 months (P < 0.001) but improved in comparison with 12 months (P < 0.001). Thirty-four patients completed the BII survey, with 18% reporting symptoms at 3 months and 29% at 1 year. Zero patients requested explantation. Conclusions: Transwomen exhibit a significant increase in breast, psychosocial, and sexual well-being after breast augmentation. However, patients experienced a decreased physical well-being, and many report symptoms associated with BII. These results can be used to better counsel these individuals preoperatively and set reasonable postoperative expectations. Further studies investigating long-term satisfaction in larger cohorts are needed.

Ethnic Disparities in Thrombotic and Bleeding Diatheses Revisited: A Systematic Review of Microsurgical Breast Reconstruction across the East and West.

BACKGROUND: Ethnicity has been shown to play a role in disparate coagulative responses between East Asian and Caucasian patients undergoing nonmicrovascular surgery. In this study, we sought to further investigate this hematologic phenomenon between the two ethnic groups within the field of microsurgical breast reconstruction. METHODS: A systematic review examining the reported incidence of microvascular thrombosis and all-site bleeding among breast free flaps in East Asians and Westerners was performed. Statistical analysis was performed using the chi-square test. RESULTS: Ten East Asian studies with 581 flaps and 99 Western studies with 30,767 flaps were included. A statistically significant higher rate of thrombotic complications was found in Westerners compared with East Asians (4.2 vs. 2.2%, p = 0.02). Conversely, bleeding events were more common in East Asians compared with Westerners (2.6 vs. 1.2%, p = 0.002). CONCLUSION: There appears to be an ethnicity-based propensity for thrombosis in Westerners and, conversely, for bleeding in East Asians, as evident by the current systematic review of microvascular breast reconstruction data. It is therefore advisable to consider ethnicity in the comprehensive evaluation of patients undergoing microsurgical procedures.

Efficacy of Hydromechanical Therapy in Nonhealing, Chronic Wounds as a Cost- and Clinically Effective Wound Care Modality.

INTRODUCTION: Chronic wounds pose a widespread challenge to health care, with many new, costly wound care modalities introduced in recent years with varying degrees of success. Bacterial biofilms have been postulated as one of the main culprits of the stagnation of chronic wound healing. For years, surgical fields have used pressurized irrigation for cleansing surgical wounds, but its utility in managing nonhealing chronic wounds has often been overlooked. OBJECTIVE: In this case series, the authors aimed to demonstrate that hydromechanical therapy with pressurized irrigation can be a cost-effective and clinically effective wound care modality. MATERIALS AND METHODS: The authors present 6 clinical cases of difficult nonhealing wounds managed with hydromechanical therapy with pressurized irrigation, a follow-up from the initial case report. Other, often more expensive modalities, had previously failed. In all 6 cases, irrigation was performed using tap water or saline either at home or long-term care facilities. Literature that focused on the mechanism of healing from hydromechanical therapy was reviewed. RESULTS: All chronic wounds in the series reached stable healing. The authors speculate that such healing was achieved through biofilm disruption and tissue stimulation with a mechanical impact. Literature supporting this hypothesis is presented. CONCLUSIONS: The current clinical results offer a new perspective on the role of a traditional surgical modality of hydromechanical therapy in chronic wound care and on the associated opportunity of potential cost savings.

Exosomes Are Comparable to Source Adipose Stem Cells in Fat Graft Retention with Up-Regulating Early Inflammation and Angiogenesis.

BACKGROUND: Exosomes derived from mesenchymal stem cells possess functional properties similar to those of their parent cells, suggesting that they could play a pivotal role in tissue repair and regeneration. METHODS: Using lipotransfer as a surrogate, exosomes were isolated from mouse adipose-derived stem cell-conditioned medium and characterized. Minced fat tissue mixed with exosomes, source cells (cell-assisted lipotransfer), or saline was implanted subcutaneously in the lower back of C57/BL mice bilaterally (n = 16 each). Transferred fat tissues were harvested and analyzed at 3 and 10 weeks. RESULTS: At 3 and 10 weeks after the transfer, fat grafts in groups of exosomes and cell-assisted lipotransfer showed better fat integrity, fewer oil cysts, and reduced fibrosis. At week 10, graft retention rates in cell-assisted lipotransfer (50.9 ± 2.4 percent; p = 0.03) and exosome groups (56.4 ± 1.6 percent; p < 0.001) were significantly higher than in the saline group (40.7 ± 4.7 percent). Further investigations of macrophage infiltration, inflammatory factors, angiogenic factors, adipogenic factors, and extracellular matrix revealed that those exosomes promoted angiogenesis and up-regulated early inflammation, whereas during mid to late stages of fat grafting, they exerted a proadipogenic effect and also increased collagen synthesis level similarly to their source cells. CONCLUSIONS: The adipose-derived stem cell-derived exosomes demonstrated effects comparable to those of their source cells in achieving improved graft retention by up-regulating early inflammation and augmenting angiogenesis. These features may enable exosomes to be an attractive cell-free alternative in therapeutic regenerative medicine.

An Overlooked but Effective Wound Care Methodology: Hydromechanical Therapy Revisited.

Chronic wounds are frequently difficult, expensive to treat, and pose a significant burden on both the patient's quality of life and health care system. Their recalcitrance to treatment stems from multiple factors, particularly the presence of bacterial biofilms within the wound bed. However, a commonly overlooked modality in the field of wound care, pressurized irrigation, offers an inexpensive mechanical debridement force capable of dislodging these biofilms that contribute to delayed healing of chronic wounds. We present here a single clinical case of a difficult nonhealing wound that had previously failed 3 months of negative-pressure wound therapy, a much more expensive modality. This chronic plantar foot wound was treated with daily application of hydromechanical therapy using tap water at home. It achieved a stable granulation surface, and with a small skin graft, healing with no recurrence seen at 15-month follow-up. We speculate that a combination of tissue stimulation and disruption of the wound surface biofilm contribute to improved healing, supporting a reevaluation for the use of pressurized irrigation in the treatment of chronic wounds.

Porcelain Gallbladder: Is Observation a Safe Option in Select Populations?

BACKGROUND: Management of gallbladder wall calcifications has been controversial for many decades. Although the traditionally perceived strong association with gallbladder cancer mandated prophylactic cholecystectomy, newer evidence suggests a much lesser association and might indicate an observational approach. STUDY DESIGN: A retrospective cohort study of 113 patients with gallbladder wall calcifications diagnosed between 2004 and 2016 at a single institution was conducted. Radiographic re-review identified patients with definitive (n = 70) and highly probable (n = 43) gallbladder wall calcifications. Patients were categorized according to their designated treatment plan. RESULTS: In the observation group (n = 90), delayed cholecystectomy for gallbladder-related symptoms was necessary in 4 patients (4%). None of the patients in this group were diagnosed with a gallbladder malignancy during a mean of 3.2 ± 3.2 years follow-up. In the operative group (n = 23), peri-operative complications occurred in 13%, and gallbladder malignancy was found in 2 patients. In comparison, although patients in the observation group were older and had more comorbidities, the rate of adverse events was not significantly different (4% vs 13%; p = 0.15) with an overall low risk for potentially life-threatening complications to the patient when observed clinically. CONCLUSIONS: For management of gallbladder wall calcifications, observation appears to provide no significant difference in adverse events, including the risk of gallbladder malignancy developing, compared with an operative approach. Although there is a need for intervention in the presence of symptoms and findings suggestive of malignancy, prophylactic cholecystectomy should be avoided in patients with limited life expectancy and significant comorbidities.
