Expander graphs are useful in the design and analysis of communication networks. Mukhopadhyay et al. introduced a method to generate a family of expander graphs based on nongroup two predecessor single attractor Cellular Automata(CA). In this paper we propose a method to generate a family of expander graphs based on 60/102 Null Boundary CA(NBCA) which is a group CA. The spectral gap generated b...

Pulmonary agenesis is a rare congenital disorder with large variability in presentation and prognosis. We describe a full-term infant born with right-sided pulmonary agenesis who underwent thoracoscopic placement of a tissue expander. He ultimately died of pulmonary hypertension. Immunohistology showed intimal hyperplasia without the loss of endothelial caveolin-1 expression. A literature revie...

Infection is a common complication of immediate breast reconstruction that often leads to device removal, a result emotionally devastating to the patient and frustrating for her surgeon. "No-touch" techniques have been used in other surgical disciplines and plastic surgery, but they have not been reported for breast reconstruction with tissue expanders or implants and acellular dermis. We repor...

Abstract Goals/Purpose Breast tissue expansion has a reported infection rate ranging from 2.4-25% in the literature when used for post mastectomy breast reconstruction. Expander infections may prolong reconstructive timeframe, increase costs, portend poorer aesthetic outcomes, and decrease patient satisfaction. Medical treatments are often attempted to salvage implants prior surgical treatment ...

BACKGROUND AND PURPOSE The latissimus dorsi myocutaneous flap (LDMF) used to be the standard practice for breast reconstruction; however, with the increased use of tissue expanders and the development of the transverse rectus-abdominis myocutaneous flap for autologous tissue breast reconstruction, its use has decreased. To reassess the role of the LDMF in breast reconstruction, a prospective st...

Breast reconstruction with tissue expander is known to be the most painful procedure among breast surgical procedures and is more painful than mastectomy or axillary dissection [1]. This fact was confirmed with National Mastectomy and Breast Reconstruction Audit in England in 2011 [2]. Severe pain was traditionally treated with intravenous narcotic analgesia. We are still searching for more eff...
