RESUMO
INTRODUCTION: Several studies have evaluated the effect of liposuction or abdominoplasty on metabolic health, including insulin resistance, with mixed results. Many overweight patients, with no marked obesity, are recommended to undergo liposuction combined with abdominoplasty, but no study has evaluated the effectiveness of combining the two procedures on metabolic health. METHODS: The present prospective cohort study compares the metabolic parameters of 2 groups of normoglycemic Hispanic women without obesity. The first group underwent liposuction only (LIPO), while the second group had combined liposuction and abdominoplasty (LIPO + ABDO). RESULTS: A total of 31 patients were evaluated, including 13 in the LIPO group and 18 in the LIPO + ABDO group. The 2 groups had similar HOMA-IR before surgery (P > 0.72). When tested 60 days after surgery, women in the LIPO group had similar HOMA-IR compared to their preoperative levels (2.98 ± 0.4 vs 2.70 ± 0.3; P > .20). However, the LIPO+ABDO group showed significantly reduced HOMA-IR values compared to their preoperative levels (2.37 ± 0.2 vs 1.73 ± 0.1; P < .001). In this group, this decrease also positively correlated with their preoperative HOMA-IR (Spearman r = 0.72; P < .001) and, interestingly, we observed a negative correlation between the age of the subjects and the drop in HOMA-IR after surgery (Spearman r = -0.56; P < .05). No changes were observed in the other biochemical parameters that were assessed. CONCLUSIONS: These data suggest that, when combined with abdominoplasty, liposuction does improve insulin resistance in healthy Hispanic females. More studies are warranted to address this possibility.

Background: Color-coded duplex sonography (CCDS) is a widely proposed noninvasive diagnostic tool in microsurgery. CCDS has been applied to lower extremity salvage cases to define appropriate blood flow velocity criteria for achieving arterial success in diabetic foot and complex microsurgery cases. This study aimed to compare the success ratio of free flaps when using CCDS versus cases where CCDS was not used. Methods: We included complex microsurgery cases from 2019 to 2021. These cases were subsequently categorized into two groups: group A consisted of cases where CCDS parameters were applied, whereas group B comprised cases where CCDS was not performed at all. Results: The study encompassed 14 cases (11 men and three women). The age range varied from 23 to 62 years, with an average age of 42. Using CCDS analysis and planning demonstrated improved outcomes in comparison with cases where CCDS was not performed, albeit without statistical significance (Pâ =â 0.064). Conclusions: The application of CCDS proves to be beneficial in the realm of microsurgery. Although not achieving statistical significance, our data imply that CCDS utilization holds promise for enhancing microsurgical procedures.
RESUMO
Introduction In aesthetic surgery, we have a few evaluation tools that numerically and objectively measure the changes we make in patients. This article aimed to evaluate the nasal systematic analysis and compare findings between the three systems of nasal evaluation: photographs 2D, 3D surface imaging with the Kinect system, and 3D CT scan imaging. Methods We designed a longitudinal and descriptive prospective study with simple non-blind randomization. To compare the systematic nasal analysis between the three methods. If the findings are similar, all three methods would be useful in independent clinical scenarios. Results A total of 42 observations were included finding a minimum age of 21 with a mean of 28 years old. Also, 64% were female, 93% had adequate facial proportions, and 50% were Fitzpatrick III. For outcome statistics, we found differential nasal deviation between 3D images with a mean of 6.53 mm. While when comparing the nasal dorsum length, we found a statistical significance of p = 0.051. When comparing the nasal dorsum length index, we found no significant difference p = 0.32. Also, we did not find statistical significance when comparing the nasofrontal angle and tip rotation angle p = 1 for both. Conclusion We found that the population we serve has characteristics of Hispanic mestizo nose. The three methods seem to evaluate systematic nasal analysis in a very similar way, and any of them can be used depending on the scenario and the needs of plastic surgeons.
RESUMO
INTRODUCTION: Zone I extensor tendon lesion accompanies an avulsion fracture of the bone insertion. A common complication of traditional pull-out is the necrosis of the site of the button in the finger pad. Zhang described an alternative way of anchoring the cerclage to the Kirschner Wire (K-wire) to relieve the pressure in the finger pad. He describes the use of wire cerclage, for fracture reduction. The objective of this paper is to perform a comparison between wire and nylon using Zhang pull-out technique. MATERIAL AND METHODS: We performed a cohort study comparing Nylon versus Wire in Zhang technique. Comparing cosmetic satisfaction, stiffness, residual pain, and Crawford scale. RESULTS: When comparing the outcomes between both groups, we found no statistical difference in cosmetic satisfaction (p = 0.285), stiffness (p = 0.460), and residual pain (p =1.000), overall complications (p = 1.000), or Crawford scale (p = 1.000). We only found a significant statistical difference in pain when removing the cerclage, being greater in Group B (p = 0.008). CONCLUSIONS: We found no significant outcome difference between nylon and wire cerclage. However, at the time of removing it, patients experience less pain.

Free-flap monitoring is challenging to perform in some centers. It requires the availability of trained health care personnel for 24 hours a day and seven days a week. Many methods had been proposed for flap monitoring, and none of them are superior to clinical evaluation. This study aimed to present a murine model to evaluate the accuracy (sensitivity, specificity, and the positive or negative predictive values) of a device. Wistar rats weighing 240-490 g were included for intervention and data collection. A murine model of left inferior epigastric vessel flaps was implemented. Intermittent pedicle clamping was performed to calculate the accuracy of the device that detects flow obstruction. The general variables studied were age, weight, and gender. The sensitivity, specificity, and negative or predictive values were calculated. The results showed a sensitivity of 97%, a specificity of 95% with a positive predictive value of 95%, and negative predictive value of 97%. The sensitivity and specificity showed excellent results within the range of clinical security. We require more data to analyze the multiparameter monitoring to see if it is feasible and cost-effective.
RESUMO
BACKGROUND: Since the description of superficial fascia flap harvesting, a new window of opportunity has been open in obese patients, where a higher subcutaneous thickness of tissue is present. To our knowledge, the impact of body mass index on superficial fascial flaps has not been reported. METHODS: We recruited 122 patients from April 2019 to January 2020. From these patients, the 3 most common thinned flaps were selected: the superficial circumflex iliac perforator flap; the anterolateral thigh flap at the perforator A, B, and C; and the thoracodorsal flap. Two vertical measures were registered: the distance from the skin to the superficial fascia, and from this point to the deep fascia. RESULTS: The average flap measurement presented here was within the range, as previous clinical studies. The superficial fatty layer thickness in the superficial circumflex iliac perforator and anterolateral thigh flap was somewhat similar in thickness between overweight and obese patients, showing a minimal increase with higher body mass index. The anterolateral thigh flap was found thicker among women, and no statistical difference was shown between age groups in any of the flaps. CONCLUSIONS: A better understanding of the fat layers' thickness will result in better planning, minimizing secondary debulking procedures, decreasing operative time, and reducing general complications among obese patients. Thus, a better understanding of flap structure and physiology in obese patients will lower complications and give more predictable results.
RESUMO
Los osteocondromas o endocondromas son tumores benignos de cartílago hialino maduro que crecen en las metáfisis de los huesos tubulares de la mano, y son lesiones primarias solitarias o múltiples. Cuando los encondromas aparecen en la infancia, en forma múltiple y sin un patrón hereditario conocido, se denomina enfermedad de Ollier. En esta enfermedad, la afección tiene un predominio unilateral, que compromete principalmente manos y pies. El presente caso es de un paciente de 18 años con enfermedad de Ollier desde los dos años de edad con afección de manos y pies, el cual acude a nuestro servicio con una severa deformidad y disfuncionalidad de antebrazo y mano derecha. El paciente se manejó con una amputación estético funcional de los dedos cuarto y quinto, así como resección de los encondromas de los dedos segundo y tercero de la mano derecha. A diferencia de los pocos casos reportados en la literatura de enfermedad de Ollier con afección de manos, este paciente, evolucionó con recidivas sin regresión ni autolimitación, afectando, finalmente a las cuatro extremidades.
