his burden, making it more acceptable and feasible.More than 75% of major limb amputees experience chronic pain; however, data on severity and experience of pain are inconsistent. Without a benchmark using quantitative patient-reported outcomes, it is difficult to critically assess the efficacy of novel treatment strategies. Our primary objective is to report quantitative pain parameters for a large sample of amputees using the validated Patient-reported Outcomes Measurement System (PROMIS). Secondarily, we hypothesize that certain patient factors will be associated with worse pain.
PROMIS and Numerical Rating Scales for residual limb pain (RLP) and phantom limb pain (PLP) were obtained from a cross-sectional survey of upper and lower extremity amputees recruited throughout North America via amputee clinics and websites. Demographics (gender, age, race, and education) and clinical information (cause, amputation level, and time since amputation) were collected. Regression modeling identified factors associated with worse pain scores (
< 0.05).
Seven hundred twenty-seven surveys were analyzed, in which 73.4% reported RLP and 70.4% reported PLP. Median residual PROMIS scores were 46.6 [interquartile range (IQR), 41-52] for RLP Intensity, 56.7 (IQR, 51-61) for RLP Behavior, and 55.9 (IQR, 41-63) for RLP Interference. Similar scores were calculated for PLP parameters 46.8 (IQR, 41-54) for PLP Intensity, 56.2 (IQR, 50-61) for PLP Behavior, and 54.6 (IQR, 41-62) for PLP Interference. Female sex, lower education, trauma-related amputation, more proximal amputation, and closer to time of amputation increased odds of PLP. Female sex, lower education, and infection/ischemia-related amputation increased odds of RLP.
This survey-based analysis provides quantitative benchmark data regarding RLP and PLP in amputees with more granularity than has previously been reported.

Nevertheless, it plays an important role in the final stages of patient rehabilitation after traumatic events, treatment of deformations, and oncoplastic surgery, and in unique cases of purely aesthetic reconstruction. We present a clinical case of lower limb reconstruction with a prefabricated bipedicled deep inferior epigastric artery (DIEP) flap in a young patient who underwent a massive congenital circular pigmented nevus excision surgery. Due to the lack of sufficient donor site tissues anywhere on the body, a bilateral DIEP flap was prefabricated using tissue expansion. Two expanders were used to prepare the donor site. Six months after expansion, lower limb reconstruction was performed. this website A large (50 × 25cm2) surgical defect was covered by a prefabricated DIEP flap. Flap positioning was regarded with extra care due to importance of proper venous outflow in accordance with lower limb venous anatomy. Treatment results were above the satisfactory level both aesthetically and therapeutically. Aesthetic and therapeutic incentives were assessed before surgical treatment decision. Large defects of the lower limbs require significant amount of excess tissue in the donor site and may require prefabrication. In young patients with low BMI, flap transfer is nearly impossible without prior expansion. In this case, we successfully performed giant pigmented nevus excision, with immediate reconstruction with a prefabricated bilateral DIEP flap. Venous outflow was problematic due to the anatomical structure of lower limb veins. This required extra venous drainage and special regard to positioning of the flap.YVOIRE Classic s (YC) and Restylane (RES) have similar rheological properties, which suit mid-dermis injection, while the rheological properties of YVOIRE Volume s (YV) are comparable to those of Perlane (PER), which suit deep dermis injection to treat deep wrinkles. Two similarly designed studies aimed to evaluate the performance and safety of YC and YV injected into the nasolabial folds (NLFs).
These were split-face designed, evaluator-blind, noninferiority studies. Fifty-eight subjects with moderate-to-severe NLFs were enrolled in the first study and treated with YC and RES, and 57 subjects were enrolled in the second study and treated with YV and PER. The Wrinkle Severity Rating Scale ranged from 1 (no visible fold) to 5 (extremely deep and long folds), and subject satisfaction was evaluated.
The least squares mean Wrinkle Severity Rating Scale scores (standard error) at week 26 were 2.56 (0.09) for both YC- and RES-treated NLFs and 2.89 (0.08) and 2.91 (0.08) for YV- and PER-treated NLFs, respectively. The difference between the groups was 0 and 0.02, and the lower limit of its 95% confidence interval was -0.0725 and -0.0125, which was greater than the predefined margin (-0.29), proving the noninferiority of YC and YV to RES and PER, respectively. The safety profiles and subject satisfaction of YC and YV were similar to those of RES and PER, respectively.
YC is comparable to RES and YV is comparable to PER in terms of performance and safety profiles, with NLF-correcting effects lasting for up to 26 weeks.

Sclerotherapy and surgical resection have been frequently applied; however, both are far from being minimally invasive in terms of aesthetic satisfaction, including the aesthetic downtime. We performed a less-invasive treatment using the venous anastomosis technique, named the lymphatic malformation-venous anastomosis (LMVA), mainly in pediatric patients with intractable microcystic lesions, in whom general anesthesia was required because the pediatric patients could not remain still. Here, we report the case of a 35-year-old man with a cystic submandibular LM successfully treated with LMVA under local anesthesia. He presented with a gradually enlarging LM on the neck. For improving aesthetics, LMVA was planned under local anesthesia. Lymphography by injecting indocyanine green revealed no inflow or outflow connection to the malformation; thus, we created an outflow bypass using the sidewall of the LMVA technique.
