RESUMEN
The ongoing outbreak of the monkeypox virus (now referred to as "mpox") was deemed a public health emergency by the World Health Organization in 2022. The United States now reports the highest number of mpox cases, with 29 980 cases and 21 deaths as of January 11, 2023. The most common presenting symptom is a pruritic, vesicular rash that commonly involves the hands. While covering hand call, our division has encountered 2 cases of mpox in the emergency department for which the chief complaint was a hand lesion. Because hand surgeons will be called upon to make an initial diagnosis, the purpose of these case reports is to describe the presentation, disease course, treatment, and outcomes of these mpox patients. These patients had both uncontrolled HIV as well as other sexually transmitted disease. Symptoms included painful vesicular hand lesions with ulceration and eventual central necrosis, followed by similar lesions on the face, trunk, and genital area. Diagnosis was made using nucleic acid amplification testing through polymerase chain reaction. The patients were treated with restoration of immunity through control of HIV as well as treatment of all secondary bacterial infections. One patient died in the hospital, and the other survived without any long-term defects.

SUMMARY: An aesthetically pleasing umbilicus is a critical component to the overall cosmesis and resultant patient satisfaction after deep inferior epigastric artery perforator (DIEP) flap breast reconstruction. Because of variables in body habitus, comorbidities, and technical aspects of the procedure, patients undergoing DIEP flap breast reconstruction are at a higher risk of umbilical complications and poor aesthetic appearance of the neoumbilicus compared with those undergoing cosmetic abdominoplasty. To minimize these potential problems and maximize the overall aesthetic appearance of the abdomen, the authors propose an algorithmic approach to umbilical inset after DIEP flap harvest that takes into account several critical factors: the thickness of the subcutaneous tissue of the abdominal flap, the length of the umbilical stalk, and the depth of the umbilical bowl. This simple algorithmic approach is a useful tool that will assist surgeons in minimizing umbilical complications and delivering a superior cosmetic appearance to the abdominal donor site in DIEP flap reconstruction.

SUMMARY: The muscle-sparing thoracotomy offers several benefits over the traditional posterolateral thoracotomy approach for surgically accessing the chest cavity. Some of the potential advantages of preserving the latissimus dorsi and serratus anterior muscles include both functional benefits and potential use of these muscles for future flap reconstruction. Nevertheless, the muscle-sparing thoracotomy technique has traditionally been described with a wide exposure and, as a result, a theoretically higher risk of seroma and hematoma formation due to the increased dead space. The authors propose a new approach to muscle-sparing thoracotomy to avoid the disadvantages of each technique. By defining two subcutaneous anatomical triangles that can be safely lifted without disrupting the latissimus dorsi and serratus anterior muscles' blood supply, this novel approach provides good exposure, preserves muscle flaps for future use, and minimizes dead space. As a result, this novel muscle-sparing thoracotomy technique has the potential to minimize postoperative complications and maximize patient outcomes.

Total and subtotal sternectomy oncological defects can result in large deficits in the chest wall, disrupting the biomechanics of respiration. Reviewing the current literature involving respiratory function and rib motion after sternectomy, autologous rigid reconstruction was determined to provide the optimal reconstructive option. We describe a novel technique for sternal defect reconstruction utilizing a double-barrel, longitudinally oriented, vascularized free fibula flap associated with rib titanium plates fixation. Our reconstructive approach was able to deliver a physiological reconstruction, providing rigid support and protection while allowing articulation with adjacent ribs and preservation of chest wall mechanics.
RESUMEN
SUMMARY: The progress of biotechnology, medical instruments, and applied sciences contributes to a rapidly expanding space for the advancement of the medical field. Surgeons experience first-hand the limitations of current medical devices and thus have unique insight into problems that could be solved with new products. The process of turning an idea into a product capable of success in the marketplace, however, is often unfamiliar to surgeons. The authors seek to illuminate this process and provide an ordered list of tasks that can make bringing ideas to market more achievable for surgeons. The first step in this process is the generation and protection of a new idea. Next, the process of making an idea into a product is outlined. This phase involves team assembly, business planning, and product development. Market research and valuation are key to understanding how a product can be applied in the market, and meticulous research during this phase allows for informed decision-making that will help secure funding down the road. Finally, various options for financing are discussed and compared to help surgeon-entrepreneurs find an option that best fits their project, and steps to maximize leverage are described. The development of new products can be a complicated process for surgeons. Organized into four phases, with ordered instructional steps to advance through each phase, the process of bringing an idea to the market is clarified. Facilitating this process will possibly contribute to the continual improvement of medical and surgical abilities through the introduction of new devices and technologies.

BACKGROUND: As power-assisted liposuction (PAL) gains in popularity, plastic surgeons operating these devices experience occupational exposure to hand-transmitted vibration, which can result in hand-arm vibration syndrome, a debilitating neurovasculopathy. OBJECTIVES: The objective of the study was to determine vibration exposure from the utilization of a PAL device during surgery to generate recommendations for safe use. METHODS: Vibration emission of a commonly utilized PAL system (MicroAire-650, Surgical Instruments, Charlottesville, VA) was examined employing a vibration data logger under both controlled laboratory conditions and during 13 typical liposuction cases. Data were analyzed and compared with established safety limits of vibration exposure. RESULTS: The experiments demonstrated a mean vibration magnitude of typical liposuction surgeries to be 5.69â ±â 0.77 m/s2 (range, 4.59-6.27 m/s2), which is significantly higher than the manufacturer declared value of 3.77 m/s2. Cannula size was shown to be the most significant contributor to vibration magnitude, with larger cannulas causing more vibration transmission. CONCLUSIONS: These results indicate that recommendations must be made to prevent undue occupational exposure to vibration from PAL. The MicroAire-650 can generally be safely utilized for less than 1.5 h/d. At exposure levels >1.5 h/d, there is increased risk of developing vibration-related injuries, and vibration-reducing strategies should be implemented. At exposure levels >6 h/d, the safety limit is exceeded and there is significantly increased risk of developing hand-arm vibration syndrome and vibration exposure should be halted.

BACKGROUND: Pneumothorax is a rare complication of liposuction resulting from injury to the lung parenchyma. OBJECTIVES: This study aimed to determine the incidence of pneumothorax complicating liposuction, describe an archetypal presentation, identify risk factors, and propose options for risk reduction. METHODS: In a retrospective chart review, liposuction procedures performed over a 16-year period by 8 surgeons in 1 practice were screened for pneumothorax. Cases featuring pneumothorax were analyzed to ascertain risk factors, presentation, and pathogenesis. RESULTS: Among the 16,215 liposuction procedures performed during the study period, 7 pneumothoraxes were identified (0.0432%). Six (85.7%) were female. Three (42.9%) had previous liposuction. Six cases (85.7%) included liposuction of the axillary region. All cases featured depression of intra/postoperative oxygen saturations as the initial sign. Three (42.9%) were identified intraoperatively. All patients were transferred to a hospital for imaging. Five (71.4%) underwent chest tube placement. Two (28.6%) were treated with observation alone. Pneumothoraxes were left-sided in 4 cases (57.1%), and right-sided in 3 cases (42.9%). In early cases, 1.5-mm infiltration cannulas were used; in 2016 cannula size was changed to 3-4 mm for infiltration and 4-5 mm for liposuction. CONCLUSIONS: Possible risk factors for pneumothorax include liposuction of the axilla, use of flexible infiltration cannulas, and scarring from previous liposuction. We recommend including pneumothorax as a potential complication during informed consent, performing infiltration with a stiff >3.5-mm cannula, minimizing positive-pressure ventilation, emphasized awareness of cannula tip location in all patients but particularly in patients with previous liposuction or scar tissue, and increased caution when operating in the axillary area.
