Pectoralis major muscle sarcomas are extremely rare and can mimic breast lesion clinically. We report a case of poorly differentiated sarcoma of the pectoralis major muscle in a 63-year-old woman of south east Asian ethnicity presenting with a progressively increasing right breast lump. Mammography, ultrasonography (US), contrast-enhanced computed tomography, and biopsy were done to make the final diagnosis. Complete surgical excision was planned but deferred due to pulmonary metastasis, and the patient was treated with palliative chemotherapy. Clinical examination may be confusing but radiological and pathological investigations provide detailed information about the location and the extent of the disease and a definitive tissue diagnosis can only be made on histopathology which will be helpful in preoperative planning and further treatment of the patient.

[Purpose] The bench press can strengthen targeted muscles, such as the pectoralis major, deltoid, and triceps brachii. This study examined differences in muscle activities during the bench press at different angles in beginners to collect basic data and evaluate the clinical effectiveness of the bench press. [Participants and Methods] The participants were 15 male students with <1 year of training experience.

Osteopetrosis is a rare systemic skeletal disorder characterized by increased bone density and mass resulting from suboptimal or impaired resorption of osteoclastic bone. Compromised bone marrow function and associated disorders of red blood cells contribute to hematopoietic abnormalities, which exacerbate the risk of complex, recurrent infections such as jaw osteomyelitis. This case report describes the treatment of a 68-year-old Korean female with autosomal-dominant osteopetrosis who presented with severe and persistent jaw osteomyelitis complicated by hematopoietic dysregulation.

Purpose: Although previous studies have compared strength-training adaptations between free weights (FW) and machine-guided exercises, those studies did not use a Smith machine (SM), which most closely replicates the exercises performed with FW. Thus, the aim of the present study was to investigate the chronic effects of strength-focused, velocity-based training regimens using FW versus SM.
Methods: Thirty-seven sport-science students (14 female) were assigned, balanced by sex and relative strength, to either an FW or SM training group.
The pectoralis major myocutaneous pedicled flap-Its past and current practice in a dedicated microsurgery service. Review of the literature, and debunking controversies.

Background: The pectoralis major myocutaneous pedicled (PMMP) flap is still considered by many a workhorse flap in head and neck (H&N) reconstruction, despite free flap surgery advancing. The authors aimed to examine this claim and associated myths and controversies by analyzing literature trends and revealing the role of the PMMP flap in a well-established microsurgery center.
Methods: The senior author's reconstructive H&N practice between 1995 and 2022 was reviewed to describe and critically judge primary and secondary PMMP flap decisions to provide invaluable lessons learned and debunk common controversies related to complex H&N reconstruction.
Application of EMG feedback for hand prosthesis control in high-level amputation: a case study.

EMG feedback improves force control of a myoelectric hand prosthesis by conveying the magnitude of the myoelectric signal back to the users via tactile stimulation. The present study aimed to test if this method can be used by a participant with a high-level amputation, and whose muscle used for prosthesis control (pectoralis major) was not intuitively related to hand function. Vibrotactile feedback was delivered to the participant's torso, while the control was tested using EMG from three different muscles.
