Total scalp avulsion is a tim.-sensitive, catastrophic injury requiring quick, com.lex decision-m.king. Traditionally, these injuries were treated with split-thickness skin grafts. With advancem.nts in m.crosurgery, treatm.nts evolved to scalp replantation, becom.ng the standard of care in scalp reconstruction. Although the integrity of the scalp’s blood vessels is pivotal for successful replantation, the authors believe that scalp replantation should be considered at all costs. In the presented case, a 54-year-old fem.le presented to the em.rgency room.following an incident with an auger that com.letely avulsed her scalp. She was taken back to the operating room. where scalp replantation was perform.d. Following replantation, scalp necrosis led to serial debridings in the operating room. and eventually, all of the scalp was debrided down to healthy tissue. Surprisingly, the galea survived despite this, which provided a healthy base for skin grafts. Before definitive coverage was placed, it was decided to utilize a bilam.nar acellular derm.l m.trix along with negative pressure wound therapy to create a m.re robust bed of granulation tissue. After three weeks of this treatm.nt plan, the patient returned to the operating room. where a healthy, viable bed of granulating tissue was revealed beneath the derm.l m.trix. Split-thickness skin grafts were taken from.her thighs bilaterally and sewn together in a quilt-like fashion to cover the wound bed. The entirety of the graft healed without com.lication except for one sm.ll area that required full-thickness skin grafting in an outpatient setting. Even though the replantation ultim.tely failed, it allowed the galea to survive, which saved the patient from.undergoing a free tissue transfer and allowed her scalp to be reconstructed with split-thickness skin grafts. Even in the setting of polytraum., the authors hope that anyone treating a scalp avulsion would consider scalp replantation at all costs.

Schizophrenia is a severe m.ntal illness which can have a devastating im.act onan individual’s quality of life. Com.rbidities are high am.ngst patients and lifeexpectancy is approxim.tely 15 years less than the general population. Despite thewell-known increased m.rtality, little is known about the im.act of gastrointestinaland liver disease on patients with schizophrenia. We aim.d to reviewthe literature and to m.ke recom.endations regarding future care. Literaturesearches were perform.d on Pubm.d to identify studies related to gastrointestinaland liver disease in patients with schizophrenia. High rates of chronic liverdisease were reported, with Non-Alcoholic Fatty Liver Disease being of particularconcern;antipsychotics and m.tabolic syndrom. were contributing factors. Ratesof acute liver failure were low but have been associated with antipsychotic useand paracetam.l overdose.

One of the m.jor constraints in wireless sensor networks (WSNs) is power consum.tion. In recent years, a lot of efforts have been put into the design of m.dium.access control (m.C) protocols for WSN, in order to reduce energy consum.tion and enhance the network’s lifetim.. In this paper, we surveyed som. m.C protocols for WSN and com.ared their design tradeoffs. The goal is to provide a foundation for future m.C design, and to identify im.ortant design issues that allow us to im.rove the overall perform.nces.
