Monoclonal antibodies (McAbs) specific for the C-proteins of chicken pectoralis major and anterior latissimus dorsi (ALD) muscles have been produced and characterized. Antibody specificity was demonstrated by solid phase radioimmunoassay (RIA), immunoblots, and immunofluorescence cytochemistry. Both McAbs MF-1 (or MF-21) and ALD-66 bound to myofibrillar proteins of approximately 150,000 daltons...

OBJECTIVE To evaluate the factors related to surgical complications, rate of gastrostomy tube (G-tube) dependence, and hospitalization in patients undergoing reconstruction with a pectoralis myocutaneous flap vs a soft-tissue revascularized flap. DESIGN Quasi-experimental case series with a historic control group. POPULATION A total of 179 patients (138 men and 41 women) with a mean (SD) ag...

Pectoralis major injuries are relatively uncommon and can pose a diagnostic challenge. Deformity and weakness of this muscle in weight lifters is typically due to traumatic tendon rupture and often requires surgical repair. However, there are other less common etiologies that can mimic the clinical presentation of pectoralis major wasting and weakness that require different treatment approaches...

Injuries to the pectoralis major muscle are relatively infrequent. The mechanism of injury is usually an eccentric shortening of the pectoralis major under heavy load, such as when performing a bench press exercise. We report a case that presented to us with a history of sudden pain in the left pectoral region while doing heavy bench press exercise. The patient sustained a type III D pectoralis...

Countless disadvantages of the "old" pectoralis major have been listed while the amazing versatility of the free flap armamentarium gives the opportunity to suit the defect deriving from virtually every ablative head and neck surgery with a tailored reconstruction. Nevertheless, pectoralis major is still the "workhorse" for head and neck reconstruction in developing countries thanks to its ease...

The study aims to assess the myotonometer parameters of major pectoralis, biceps brachialis, femoral and anterior tibialis in patients with Parkinson’s disease before after medical treatment using comparisons healthy controls. A total 49 (69.76 ± 6.39 years) 42 controls (60.48 7.62 were tested MyotonPRO one hour drug administration. Five recorded (frequency [Hz], stiffness [N/m], decrement, rel...

BACKGROUND Infected sternotomy wounds occur in 0.5 to 8.4 percent of open heart operations. They are complex problems, with a mortality rate of 8.1 to 14.8 percent despite flap closure. For closure, the pectoralis major flap has had considerable success. However, in providing coverage to the lower third of the sternum, it may be deficient. Modifications to improve closure have included a rectus...

Background: The purpose of our study is to evaluate the role of intercostal nerve block and pectoralis major muscle infiltration in postoperative pain management following subpectoral breast augmentation. Methods : This is a prospective randomized controlled study using patients as their own controls. Women undergoing primary bilateral subpectoral breast augmentation from July 2012 until July 2...

Congenital absence of shoulder girdle muscles is described in three generations of a family. The proband, a 3 year old boy, had absence of the sternocostal head of the right pectoralis major. His father had absence of the left serratus anterior and part of the left latissimus dorsi and his paternal grandfather had absence of the lower two-thirds of the left pectoralis major, with absence of the...
