Career Outcomes of Nondesignated Preliminary Surgery Residents: A Systematic Review and Meta-Analysis.

Objective: Nondesignated preliminary surgery (NDPS) residency offers postgraduate medical education with no guarantee of a subsequent categorical position. Some literature exists detailing the career outcomes of these residents, but these results are complicated by the limited scale of these studies. The purpose of this systematic review and meta-analysis is to summarize the career outcomes of these residents from the existing literature.

Sacroiliac Joint Fusion-A Shift Toward Variant Anatomy and Clinical Implications.

Objective: To investigate impact of patient factors and sacroiliac joint (SIJ) anatomical structure on SIJ fusion outcomes.

Methods: This single-center, retrospective, observational study evaluated patients diagnosed with SIJ dysfunction refractory to conservative measures who had available preoperative imaging of the sacrum and underwent SIJ fusion surgery. The impact of patient sociodemographics on pain improvement was assessed by Mann-Whitney U test.

3-Dimensional Exoscope for Far Lateral Approach to Pontomedullary Cavernous Malformation.

Brainstem cavernous malformations account for 15%-18% of all central nervous system cavernomas and are histologically characterized by thin-walled, low-pressure capillaries, classically without intervening brain tissue. Cavernomas may be sporadic, typically characterized by a single lesion, or inherited. The inherited form is most often autosomal dominant with incomplete penetrance and variable expression.

Prevalence of Visible Subdural Spaces in Benign Enlargement of Subarachnoid Spaces in Infancy: A Retrospective Analysis Utilizing Magnetic Resonance Imaging.

Objective: Benign Enlargement of the Subarachnoid Spaces in Infancy (BESSI) is a common finding during workup for progressive macrocephaly. BESSI has been associated with slightly higher prevalence of subdural (SD) spaces and a risk for developing subdural hematoma. This study utilizes fast brain magnetic resonance imaging (MRI) to investigate the prevalence of visible SD spaces in BESSI.

Identification of Neuronal Lineages in the Drosophila Peripheral Nervous System with a "Digital" Multi-spectral Lineage Tracing System.

Elucidating cell lineages provides crucial understanding of development. Recently developed sequencing-based techniques enhance the scale of lineage tracing but eliminate the spatial information offered by conventional approaches. Multi-spectral labeling techniques, such as Brainbow, have the potential to identify lineage-related cells in situ.

Outcome of Dupuytren Contractures After Collagenase Clostridium Histolyticum Injection: A Single-institution Experience.

Background: Collagenase clostridium histolyticum (CCH) injection is an alternative to surgery for patients with Dupuytren disease (DD) of the metacarpophalangeal (MCP) and proximal interphalangeal (PIP) joints. The success of surgical and nonsurgical treatment modalities for DD is reported to vary widely between 25% and 80% (J Bone Joint Surg Am. 1985;67:1439-1443; Plast Reconstr Surg.

Hand and forearm reconstruction after skin cancer ablation.

Skin cancer is common on the dorsum of the hand and forearm. The reconstructive challenges in this area are significant, and the options are myriad. Thus, the surgeon who takes on this challenge must know the various options.

Bilateral lipoma arborescens of the bicipitoradial bursa.

A 37-year-old military mechanic presented to our institution with a chronic history of a slowly enlarging left elbow antecubital fossa mass. There was no history of other chronic illness or trauma. Magnetic resonance imaging (MRI) and excisional biopsy revealed fatty villi and synovial inflammation within the left bicipitoradial bursa, consistent with lipoma arborescens.
