Purpose: Identification and targeting of actionable oncogenic drivers (AODs) in advanced non-small-cell lung cancer (NSCLC) has dramatically improved outcomes. However, genomic testing uptake is variable and hampered by factors including slow turnaround time, frequently resulting in initial non-tyrosine kinase inhibitor (TKI) treatment. We investigate how this behavior affects outcomes.

Article Synopsis
  • Conventional teaching in managing partial hand amputations often focuses on maximizing residual limb length through various flap techniques, but only a few flaps effectively mimic the thin and flexible nature of dorsal hand skin.
  • Excessive soft tissue from flap reconstructions can hinder limb function, prosthesis fit, and the efficacy of myoelectric prosthetics.
  • Advancements in prosthetic technology and nerve transfer methods have led to a new reconstruction approach prioritizing minimal tissue coverage, resulting in faster, more secure fittings and enhanced usability of both basic and advanced partial hand prostheses.

Article Synopsis
  • The study aimed to assess whether individuals with unilateral congenital upper limb amputation can control myoelectric prostheses with multiple degrees of freedom using pattern recognition (PR) technology.
  • Seven participants, aged 9 to 62, were tested on their ability to control a virtual prosthesis through electromyographic signals, measuring their proficiency in a game-like testing environment.
  • Results showed that all participants successfully calibrated the prosthesis controls at various degrees of freedom, with no differences in accuracy between their amputated and sound limbs, indicating a promising potential for myoelectric prostheses in this population.

Background: As a component of the Maintenance of Certification process from 2003 to 2019, the American Board of Plastic Surgery tracked 20 common plastic surgery operations. By evaluating the data collected over 16 years, the authors are able to examine the practice patterns of pediatric/craniofacial surgeons in the United States.

Methods: Cumulative tracer data for cleft palate repair was reviewed as of April of 2014 and September of 2019.

Spasticity is a movement disorder characterized by a velocity-dependent increase in muscle tone and a hyperexcitable stretch reflex. Common causes of spasticity include cerebral palsy, spinal cord injury, and stroke. Surgical treatment plans for spasticity must be highly individualized and based on the characteristics of patients and the spasticity in order to maximize functional gains.

Background: The relative effects of skin growth and stretch during tissue expansion have not been studied. The authors use novel analytic techniques that allow calculation of these factors at any point of a skin patch.

Objective: The authors sought to determine how stretch and growth change with different expansion rates and to correlate these values with histologic and cellular changes in skin.

Millions of children undergo general anesthesia for surgical procedures each year, the implications of which are not fully understood. Animal models demonstrate neurotoxicity and long-term cognitive impairment following exposure to common general anesthetic agents. However, it is unclear if human brains are affected in a similar fashion and what-if any-the implications on cognitive development may be.

Tissue expansion is a popular technique in plastic and reconstructive surgery that grows skin in vivo for correction of large defects such as burns and giant congenital nevi. Despite its widespread use, planning and executing an expansion protocol is challenging due to the difficulty in measuring the deformation imposed at each inflation step and over the length of the procedure. Quantifying the deformation fields is crucial, as the distribution of stretch over time determines the rate and amount of skin grown at the end of the treatment.

The approach to rehabilitation of upper extremity injuries in athletes differs from traditional rehabilitation protocols. In general, athletes have higher functional demands and wish to return to competitive sport in a timely manner. Comprehensive rehabilitation must therefore be balanced with a timely and safe return to sport.

Botulinum toxin type A (BTA) can be used for facial aesthetics. The 3 currently available BTA types include onabotulinumtoxinA (Botox; Botox Cosmetic, Allergan, Irvine, CA), abobotulinumtoxinA (Dysport; Ipsen, Ltd, Berkshire, UK), and incobotulinumtoxinA (Xeomin; Merz Pharmaceuticals, Frankfurt, Germany). The mechanism of action and clinical uses for treatment of dynamic lines of the forehead, brow, glabella, lateral orbit, nose, and lips are presented, as well as treatment of masseter hypertrophy, platysmal bands, and improvements of the perioral region.

Background: The introduction of neuromodulators for aesthetic facial improvements greatly expanded the limits of nonsurgical facial rejuvenation. Although many current uses are considered "off-label," the widespread acceptance and favorable safety profile of properly used botulinum toxins have made them one of the most common aesthetic treatments available.

Methods: A literature review of current facial aesthetic uses of various botulinum toxin preparations was done, and general concepts were identified.

Skin expansion is a common surgical technique to correct large cutaneous defects. Selecting a successful expansion protocol is solely based on the experience and personal preference of the operating surgeon. Skin expansion could be improved by predictive computational simulations.

Targeted muscle reinnervation (TMR) offers the potential for improved prosthetic function by reclaiming the neural control information that is lost as a result of upper extremity amputation. In addition to the prosthetic control benefits, TMR is a potential treatment for postamputation neuroma pain. Here, we present our surgical technique for TMR nerve transfers in transhumeral and shoulder disarticulation patients.

Skin expansion delivers newly grown skin that maintains histological and mechanical features of the original tissue. Although it is the gold standard for cutaneous defect correction today, the underlying mechanisms remain poorly understood. Here we present a novel technique to quantify anisotropic prestrain, deformation, and growth in a porcine skin expansion model.

Skin is our interface with the outside world. In its natural environment, it displays unique mechanical characteristics, such as prestretch and growth. While there is a general agreement on the physiological importance of these features, they remain poorly characterized, mainly because they are difficult to access with standard laboratory techniques.

The primary goal of cleft palate repair is to create an anatomically and functionally intact palate while minimally affecting maxillary growth and development. In order to produce normal speech, a child must have velopharyngeal competence, defined as the ability to completely close the velopharyngeal sphincter that separates the oropharynx and nasopharynx. The absence of this ability, termed velopharyngeal insufficiency (VPI), is seen in a wide range of patients following primary cleft palate repair.

Pediatric plastic surgery is a very rewarding and challenging field. Many of our patients are managed longitudinally, often into adulthood, and deal with complex surgical problems. The role of an experienced nurse in outpatient plastic surgery is critical to managing these complex patients.

Background: Sentinel lymph node biopsy (SLNB) has been shown to reduce many of the long-term complications associated with a traditional axillary lymph node dissection (ALND); however, short-term outcomes have yet to be characterized. This study was designed to identify trends and differences in 30-day outcomes of partial mastectomy with concurrent SLNB or complete ALND to more effectively determine which patients may be at risk for perioperative complications.

Methods: A retrospective review of the National Surgical Quality Improvement Program database from 2010 to 2011 was performed to identify all female patients undergoing partial mastectomy with concurrent ALND or SLNB.

Complete thoracic ectopia cordis is associated with a uniformly dismal prognosis. The primary challenges of this disorder are (1) returning the heart to the thoracic cavity, (2) stabilizing the chest wall, and (3) repairing the sternal defect. Previously published techniques for achieving these goals have demonstrated very limited success and/or significant morbidity.
