Tumescent dissection (TUM) combines the use of crystalloid, local anesthetic, and epinephrine to create a bloodless plane to raise skin flaps. We aim to compare outcomes of TUM versus standard electrocautery dissection in mastectomies with and without reconstruction. We conducted a retrospective cohort study of patients who underwent mastectomy by a single surgeon between January 2016 and October 2020 utilizing the electronic medical record. The primary outcome was complication rate, and the secondary outcome was operative time. Chi-squared analysis and two-sample -tests were used to examine outcomes. Among 242 patients, 141 patients underwent TUM and 101 patients underwent electrocautery. 44.68% of TUM patients experienced one or more complications compared to 59.41% of electrocautery patients (=0.024). There were fewer cases of wound healing complications in the TUM group with reconstruction compared to the electrocautery group with reconstruction (6.1% vs. 21%, =0.005). Infection rate was higher in the TUM group with reconstruction compared to the electrocautery group with reconstruction (14.3% vs. 3.2%, =0.023). There was no significant difference in rates of hematoma, seroma, skin flap necrosis, nipple areolar complex necrosis, or re-exploration by dissection technique. The mean operative time was shorter with TUM compared to electrocautery (216.09 min vs. 250.16 min, =0.016). TUM yields comparable results with decreased overall complication rates compared to electrocautery dissection. Electrocautery thermal effect may account for skin-related complications. Additionally, tumescent mastectomies have shorter length of operative time which could reduce the risk of complications associated with increased time under general anesthesia.

Diabetic foot infections: Questions for an infectious disease consultant.

Division of Infectious Disease, Department of Internal Medicine, University of Pittsburgh Medical Center, Pittsburgh, PA.

Diabetic foot infection can lead to limb amputation in approximately 17% of affected patients. Given the complex pathophysiology associated with diabetic foot infection, the goal of limb preservation is best achieved with a multidisciplinary approach and a team of providers including infectious disease consultants. However, these infections often affect populations living in nonmetropolitan areas, where access to an infectious disease physician may be limited.

Diabetic foot ulcers (DFUs) and lower extremity amputations (LEAs) threaten survival and quality of life (QoL) of patients, contributing to healthcare and economic burden. Guidelines advocate for a multidisciplinary team (MDT) approach, but limited literature exists on cost-effectiveness and collaboration with primary care. We present the outcomes of the Diabetic Foot in Primary and Tertiary (DEFINITE) Care program, an MDT initiative in Singapore across primary and tertiary care.

Electronic address:

P2X receptors (P2XRs), membrane ion channels activated by extracellular adenosine 5' -triphosphate (ATP), play a pivotal role in nociception by directly promoting pain signaling. Currently, antagonists targeting P2XRs have taken effect in alleviating various pain. The therapeutic potential of the P2X receptor family has become a central focus.

Purpose: The purpose of this study was to develop an anatomically and surgically relevant classification system for medial meniscus ramp tears from prospectively collected data from a consecutive series of patients undergoing anterior cruciate ligament (ACL) reconstruction (ACLR) with ramp tears.

Methods: A series of consecutive patients from two orthopedic surgeons between June 2021 to May 2024 undergoing ACLR with medial meniscus ramp tears were included in this study. After arthroscopic confirmation of a medial meniscus ramp tear, the tear morphology and repair technique were noted using a ramp tear diagram, operative notes, and surgical photos/videos.
