Unilateral Variation of the Left Ascending Pharyngeal Artery: A Case Report.

During routine cadaveric dissection of a 77-year-old male, a series of unique arterial variations were observed within the left anterior cervical region. Firstly, the ascending pharyngeal artery (APA) was observed branching from the common carotid artery (CCA), between the internal (ICA) and external carotid (ECA) arteries. The APA continued superiorly without branching, as is typical for APA.

A Unique Bilateral Variation of the Extensor Carpi Radialis Longus: A Case Report.

A novel combination of variations involving the extensor carpi radialis (ECR) muscle group was observed bilaterally in a 75-year-old female cadaver during routine dissection. An accessory tendon was observed arising from the extensor carpi radialis longus (ECRL) and traveling with the primary tendon through the second compartment of the extensor retinaculum. While the primary tendon inserted on the base of the second metacarpal, as is typical of ECRL, the accessory tendon inserted on the base of the third metacarpal.

Is There a Difference in Abdominal Wall Muscle Strength, Endurance, and Motor Control Following Bilateral DIEP and TRAM Flaps for Breast Reconstruction?

Background: Abdominal donor site complications in bilateral pedicled transverse rectus abdominis muscle (TRAM) have been a concern when compared with bilateral deep inferior epigastric perforator (DIEP) flap breast reconstruction. This study aimed to assess the strength, endurance, and motor control in patients undergoing DIEP and TRAM flaps.

Methods: A prospective, cohort study was performed at a single institution including patients who underwent pedicled TRAM and DIEP flap reconstruction after mastectomy from August 2017 to August 2018.

Immediate Lymphatic Reconstruction in 77 Consecutive Breast Cancer Patients: 2-year Follow-up.

Background:  Breast cancer-related lymphedema (BCRL) is a cyclical, progressive disease that begins at the time of axillary dissection and worsens in the setting of adjuvant oncologic therapies. The paradigm of lymphedema management in these patients is shifting from therapeutic surgeries and decongestive therapy to preventative surgery with immediate lymphatic reconstruction (ILR).

Methods:  After institutional review board approval, a prospective database was maintained of all patients undergoing ILR.

A Unique Variation of Quadratus Plantae in Relation to the Tendons of the Midfoot.

A novel combination of variations involving the quadratus plantae muscle (QP) and its relationship to the flexor hallucis longus (FHL) tendon was observed unilaterally in the right foot of an 88-year-old female cadaver during routine dissection. The medial head of QP was observed inserting onto the tendon of FHL rather than the tendon of flexor digitorum longus (FDL), while also contributing to an anomalous tendinous slip to the second digit in conjunction with the tendon of FHL. The tendon of FHL also gave off a slip to the third digit.

The immunologic response to severe acute respiratory syndrome coronavirus 2.

The spread of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) has precipitated the worst global pandemic in a century, which has caused millions of infections and deaths as well as massive economic repercussions. As with any pathogenic virus, it is crucial to understand its unique interactions with the human immune system so that pharmaceutical and prophylactic interventions can be deployed to effectively control the pandemic. A literature search by using PubMed was conducted in 2020 with variants of the terms "COVID-19," "SARS-CoV-2," and "immunological response.

A Case of Multiple Posterior Intercostal Artery Common Trunks in Conjunction with Additional Arterial Variations.

Several thoracic vasculature variations were observed in an 81-year-old male cadaver during routine dissection. These included 5 common trunks of posterior intercostal arteries, a descending branch of the right vertebral artery, and atypical neurovascular relationships within intercostal spaces. On the right side, two common trunks of posterior intercostal arteries were observed supplying the 4th-7th intercostal spaces and 9th-11th intercostal spaces, respectively.
