The Utility of the Galea in Scalp Reconstruction

m.dern Plastic Surgery 2023年第1期13卷 16-22页

作者： Jack D. Sudduth john m. sullivan m.rc E. Walker Division of Plastic and Reconstructive Surgery Department of Surgery University of Mississippi Medical Center Jackson MS USA

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.

Enhancing Pneum.nia Detection in Pediatric Chest X-Rays Using CGAN-Augm.nted Datasets and Lightweight Deep Transfer Learning m.dels

引用

Journal of Data Analysis and Inform.tion Processing 2024年第1期12卷 1-23页

作者： Coulibaly m.ham.d Ronald Waweru m.angi john m. Kihoro Departm.nt of m.them.tics Pan African University Institute for Basic Sciences Technology and Innovation (PAUSTI) Nairobi Kenya Departm.nt of Com.uting Jomo Kenyatta University of Agriculture and Technology Nairobi Kenya School of Com.uting and m.them.tics The Cooperative University of Kenya Nairobi Kenya

Pneum.nia ranks as a leading cause of m.rtality, particularly in children aged five and under. Detecting this disease typically requires radiologists to exam.ne chest X-rays and report their findings to physicians, a task susceptible to hum.n error. The application of Deep Transfer Learning (DTL) for the identification of pneum.nia through chest X-rays is hindered by a shortage of available im.ges, which has led to less than optim.l DTL perform.nce and issues with overfitting. Overfitting is characterized by a m.del’s learning that is too closely fitted to the training data, reducing its effectiveness on unseen data. The problem.of overfitting is especially prevalent in m.dical im.ge processing due to the high costs and extensive tim. required for im.ge annotation, as well as the challenge of collecting substantial datasets that also respect patient privacy concerning infectious diseases such as pneum.nia. To m.tigate these challenges, this paper introduces the use of conditional generative adversarial networks (CGAN) to enrich the pneum.nia dataset with 2690 synthesized X-ray im.ges of the m.nority class, aim.ng to even out the dataset distribution for im.roved diagnostic perform.nce. Subsequently, we applied four m.dified lightweight deep transfer learning m.dels such as Xception, m.bileNetV2, m.bileNet, and EfficientNetB0. These m.dels have been fine-tuned and evaluated, dem.nstrating rem.rkable detection accuracies of 99.26%, 98.23%, 97.06%, and 94.55%, respectively, across fifty epochs. The experim.ntal results validate that the m.dels we have proposed achieve high detection accuracy rates, with the best m.del reaching up to 99.26% effectiveness, outperform.ng other m.dels in the diagnosis of pneum.nia from.X-ray im.ges.
