BACKGROUND Implant malposition is becoming an increasingly recognized complication following subpectoral breast augmentation. Although several causes of medial malposition have been previously demonstrated, medial implant malposition secondary to unintended pectoralis muscle slips has not been previously described. OBJECTIVE The goal of this study is to describe a form of medial implant malpo...

We present a case of a right sided accessory head of the pectoralis major muscle located inferior to its abdominal head. This variation was found during a routine anatomy dissection at the American University of the Caribbean School of Medicine. The muscle fibres of the accessory head of the pectoralis major muscle arose from those of the serratus anterior muscle and travelled superolaterally t...

was administered, and an incision made opposite the lower border of the pectoralis major muscle in the fold of the axilla; the skin superficial and deep fascias were divided, but no large vessel was injured. Then a director was forcibly pushed iuto the axilla for about an inch and a half, before the abscess was opened. After using a little force pus appeared ; a common dressing forceps was then...

We report the transfer of the sternal part of the pectoralis major to the lower pole of the scapula in 15 patients with winged scapula. At follow-up after 1 to 16 years nine had a satisfactory result and were gainfully employed, though in four of these re-operation had been necessary. Two patients had fair results; the transplant functioned, but they had limited voluntary control. Four were fai...

In breast augmentation, surgeons usually choose a pocket location for the implant behind breast parenchyma (retromammary), partially behind the pectoralis major muscle (partial retropectoral), or totally behind pectoralis major and serratus (total submuscular). Each of these implant pocket locations has specific indications, but each also has a unique set of tradeoffs. When applied to a wide ra...

Hygienic behavior, a trait that may confer resistance to brood diseases in the honey bee Apis mellifera, was studied in two species of stingless bees in Mexico. Eight colonies each of Melipona beecheii and Scaptotrigona pectoralis were tested for hygienic behavior, the removal of dead or diseased brood, by freeze killing a comb of sealed cells containing pupae. Both species detected and removed...

The aim of this study was to investigate the DNA content and morphological characteristics of muscle fibers, and their relation to the growth performance in random bred control (RBC) and heavy weight (HW) Japanese quail lines. The 2 lines were of similar embryo size at 6 and 8 d of incubation; however, HW quail were significantly larger than their counterparts after 10 d of incubation (P < 0.05...

BACKGROUND The main benefit of neoadjuvant chemotherapy is a reduction in tumor size, which allows breast-conserving surgery (BCS) in patients who otherwise would have required a mastectomy. Breast magnetic resonance (MRI) has been proposed to evaluate tumor extent after neoadjuvant chemotherapy, to determine which patients have become eligible for BCS. AIM The aim of our study was to determi...

TECHNIQUE A skin reducing mastectomy is performed via Wise pattern incisions, retaining an extensive inferior dermal sling of de-epithelialised tissue. A sizer is used to ensure the skin envelope meets the inframammary fold before an anatomical implant is placed on the pectoralis major. Complete coverage is achieved with the inferior dermal sling, which is sutured to the pectoralis superiorly. ...
