BACKGROUND: Tunneled transposition of the facial artery myomucosal (FAMM) island flap on the lingual side of the mandible has been reported for intraoral as well as oropharyngeal reconstruction. This modified technique overcomes the limitations of short range and dentition and further confirms the flexibility of the flap. This paper presents a case of reconstructing secondary soft palatal defect due to flap necrosis following two-flap palatoplasty in irradiated patient with lingually transposed facial artery myomucosal island flap...

Adnexal torsion is the fifth most common gynecologic surgical emergency, requiring clinician and radiologist awareness. It involves the rotation of the ovarian tissue on its vascular pedicle leading to stromal edema, hemorrhagic infarction, and necrosis of the adnexal structures with the subsequent sequelae. Expedient diagnosis poses a difficult challenge because the clinical presentation is variable and often misleading. Adnexal torsion can mimic malignancy as it can take a subacute, intermittent, or chronic course, and thereby can be complicated to diagnose...

BACKGROUND: Fat grafting has been demonstrated as a means of reconstructing breast conservation therapy defects. However, there is continued uncertainty regarding its clinical efficacy and oncologic safety. Furthermore, the role of external preexpansion (i.e., with the Brava device) remains unclear in this setting. The purpose of this study was to examine the safety and clinical outcomes of Brava/fat grafting following breast conservation therapy. METHODS: A retrospective chart review was performed on all patients undergoing fat grafting following breast conservation therapy...

BACKGROUND: Radiation necrosis in eloquent areas of the central nervous system (CNS) is one of the most serious forms of toxicity from radiation therapy. The occurrence of radiation necrosis in the CNS is described in a wide range of 3 months to 13 years after radiation therapy. The incidence of this complication covers a wide range of 3-47%. The potential advantage of proton therapy is the ability to reduce dose to normal tissue and escalate tumor dose. Proton beams enter and pass through the tissue with minimal dose deposition until they reach the end of their paths, where the peak of dose, known as the Bragg peak, occurs...

Infection is a dreaded complication following 2-stage implant-based breast reconstruction that can prolong the reconstructive process and lead to loss of implant. This study aimed to characterize outcomes of reconstructions complicated by infection, identify patient and surgical factors associated with infection, and use these to develop an infection management algorithm. METHODS: We performed a retrospective review of all consecutive implant-based breast reconstructions performed by the senior author (2006-2015) and collected data regarding patient demographics, medical history, operative variables, presence of other complications (necrosis, seroma, hematoma), and infection characteristics...

The term inflammatory bowel disease (IBD) refers principally to two major categories of chronic relapsing inflammatory intestinal disorders: Crohn's disease (CD) and ulcerative colitis (UC). In the United States, it is currently estimated that about 1.5 million people suffer from IBD, causing considerable suffering, mortality and economic loss every year. Yet the cause of IBD is unknown, and until we understand more, prevention or cure will not be possible. There is a lot of variation in the incidence and prevalence of CD based on geographic region, environment, immigrant population, and ethnic groups...

Noninvasive biological readouts of tumor metastatic risk and therapeutic efficacy are needed as healthcare costs rise. CTCs are the source of metastasis in distant organs that are responsible for the majority of cancer-related deaths. Here we demonstrate the acute and long-term effect of vascular disrupting therapies (high-dose radiotherapy and tumor necrosis factor-alpha (TNF)) on CTCs released from the primary tumor with a non-invasive real-time in vivo flow cytometry system. Using our innovative flow cytometry platform, we show here that radiation and nanodrug treatment can lead to short term release of CTC from the primary tumor...

Radiation necrosis (RN) is a potential late complication of radiotherapy for intracranial malignancy, which is often associated with significant neurological morbidity. Prolonged treatment with high-dose corticosteroids or surgical resection has been the standard care for RN, but protracted steroid use can lead to significant side effects and surgical resection is not always feasible. The antivascular endothelial growth factor monoclonal antibody bevacizumab induces clinical and radiographic improvements in RN, with overall good tolerance...
