Etiology and treatment of cancer-related secondary lymphedema.

Lymphedema and specifically cancer-related lymphedema is not the main focus for both patients and physicians dealing with cancer. Its etiology is an unfortunate complication of cancer treatment. Although lymphedema treatments have gained an appreciable consensus, many practitioners have developed and prefer their own specific protocols and this is especially true for conventional (manual) versus surgical treatments.

Histologic Comparison of the Fascicular Area of Processed Nerve Allograft Versus Cabled Sural Nerve Autograft.

Background: The use of multiple cables of sural nerve autograft is common for peripheral nerve reconstruction when injured nerve caliber exceeds the nerve graft caliber. Although the optimal matching of neural to nonneural elements and its association with functional outcomes are unknown, it is reasonable to consider maximizing the neural tissue structure available for nerve regeneration. No prior studies have compared directly the cross-sectional fascicular area between cabled nerve autografts and size-selected nerve allografts.

Approach to Lymphedema Management.

Millions of people worldwide suffer from lymphedema. In developed nations, lymphedema most commonly stems secondarily from oncologic treatment, but may also result from trauma. More recently, lymphedema has been identified in patients after gender-affirmation phalloplasty reconstruction.

Transgender Scrotoplasty and Perineal Reconstruction With Labia Majora Flaps: Technique and Outcomes From 147 Consecutive Cases.

Purpose: Labia majora, the embryologic homologs of the scrotum, are ideal donor tissue for transgender scrotoplasty. The technique is detailed, and surgical outcomes are assessed for scrotoplasty using labia majora rotational advancement flaps.

Methods: We retrospectively reviewed the outcomes of phalloplasty patients who underwent either primary or secondary labia majora flap scrotoplasty and perineal reconstruction from October 1, 2017, to December 1, 2019.

Bilaminate Synthetic Dermal Matrix versus Free Fascial Flaps: A Cost-Effectiveness Analysis for Full-Thickness Hand Reconstruction.

Background:  Full-thickness injuries to the hand require durable soft tissue coverage to preserve tendon gliding and hand motion. We aim to investigate the cost effectiveness of hand resurfacing comparing free fascial flap reconstruction versus bilaminate synthetic dermal matrices.

Methods:  Cost effectiveness was modeled using decision tree analysis with the rollback method.

An abnormal clinical Allen's Test is not a contraindication for free radial forearm flap.

An abnormal clinical Allen's test is not a definitive exclusion criterion for free radial forearm flap use. A surgical Allen's test may be useful to determine whether flap harvest is feasible in patients with an abnormal clinical Allen's test.

Radial Artery Occlusion in a Patient With Lupus, Antiphospholipid Syndrome, and Raynaud Phenomenon: A Multimodal Approach.

Radial artery occlusion (RAO) is a known complication of transradial catheterization for cardiac procedures. The transradial approach has decreased bleeding complications compared with the transfemoral approach, but risks provoking hand ischemia. We present a case of a 29-year-old peripartum woman with a history of lupus, antiphospholipid syndrome, and Raynaud phenomenon who developed RAO with hand-threatening ischemia despite therapeutic anticoagulation.

CPG15 regulates synapse stability in the developing and adult brain.

Use-dependent selection of optimal connections is a key feature of neural circuit development and, in the mature brain, underlies functional adaptation, such as is required for learning and memory. Activity patterns guide circuit refinement through selective stabilization or elimination of specific neuronal branches and synapses. The molecular signals that mediate activity-dependent synapse and arbor stabilization and maintenance remain elusive.

Inhibitory dendrite dynamics as a general feature of the adult cortical microcircuit.

The mammalian neocortex is functionally subdivided into architectonically distinct regions that process various types of information based on their source of afferent input. Yet, the modularity of neocortical organization in terms of cell type and intrinsic circuitry allows afferent drive to continuously reassign cortical map space. New aspects of cortical map plasticity include dynamic turnover of dendritic spines on pyramidal neurons and remodeling of interneuron dendritic arbors.

Structural basis for the role of inhibition in facilitating adult brain plasticity.

Although inhibition has been implicated in mediating plasticity in the adult brain, the underlying mechanism remains unclear. Here we present a structural mechanism for the role of inhibition in experience-dependent plasticity. Using chronic in vivo two-photon microscopy in the mouse neocortex, we show that experience drives structural remodeling of superficial layer 2/3 interneurons in an input- and circuit-specific manner, with up to 16% of branch tips undergoing remodeling.

cpg15 and cpg15-2 constitute a family of activity-regulated ligands expressed differentially in the nervous system to promote neurite growth and neuronal survival.

Many ligands that affect nervous system development are members of gene families that function together to coordinate the assembly of complex neural circuits. cpg15/neuritin encodes an extracellular ligand that promotes neurite growth, neuronal survival, and synaptic maturation. Here we identify cpg15-2 as the only paralogue of cpg15 in the mouse and human genome.
