Article Synopsis
  • - The study aimed to evaluate how the serine protease KLK6 affects colorectal cancer development in mice with a mutant tumor suppressor gene, finding that KLK6 expression increases significantly in tumors compared to normal tissue.
  • - Techniques like immunohistochemistry confirmed KLK6 presence, and genetically altered mice lacking KLK6 showed smaller tumor sizes and fewer adenomas, indicating KLK6's crucial role in tumor growth.
  • - The research highlights KLK6 as an important factor for intestinal tumorigenesis, suggesting it could be useful for early diagnosis of colorectal cancer.

The Case for Using Evidence-Based Guidelines in Setting Hospital and Public Health Policy.

Front Surg

April 2016

Department of Otolaryngology - Head and Neck Surgery, The University of Arizona Ear Institute, The University of Arizona College of Medicine, Tucson, AZ, USA; The University of Arizona Cancer Center, The University of Arizona Bio5 Institute, Tucson, AZ, USA.

Objective: Hospital systems and regulating agencies enforce strict guidelines barring personal items from entering the operating room (OR) - touting surgical site infections (SSIs) and patient safety as the rationale. We sought to determine whether or not evidence supporting this recommendation exists by reviewing available literature.

Background Data: Rules and guidelines that are not evidence based may lead to increased hospital expenses and limitations on healthcare provider autonomy.

Hearing loss is one of the most common human sensory disabilities, adversely affecting communication, socialization, mood, physical functioning, and quality of life. In addition to age and noise-induced damage, ototoxicity is a common cause of sensorineural hearing loss with chemotherapeutic agents, for example, cisplatin, being a major contributor. Zebrafish (Danio rerio) are an excellent model to study hearing loss as they have neurosensory hair cells on their body surface that are structurally similar to those within the human inner ear.

Objective: Nearly all radiated vestibular schwannomas (VS) have solid tissue remaining at the radiation bed. The viability and proliferation capacity of this tissue has never been objectively assessed. The goals of our study were to (1) determine whether this tissue retains the morphological and immunohistochemical features of VS and (2) evaluate whether the tissue is capable of proliferation in cell culture.

The impact of cochlear implantation on cognition in older adults: a systematic review of clinical evidence.

BMC Geriatr

February 2015

Department of Otolaryngology - Head & Neck Surgery, The University of Arizona Ear Institute, The University of Arizona College of Medicine, Tucson, AZ, 85724, USA.

Background: Hearing loss is the third most prevalent chronic condition faced by older adults and has been linked to difficulties in speech perception, activities of daily living, and social interaction. Recent studies have suggested a correlation between severity of hearing loss and an individual's cognitive function; however, a causative link has yet to be established. One intervention option for management of the most severe to profound hearing loss in older adults is cochlear implantation.

The submental island flap for reconstruction of temporal bone defects.

Otol Neurotol

June 2015

*Department of Otolaryngology, The University of Arizona, Tucson; †The University of Arizona Ear Institute, Tucson; ‡Department of Surgery-Division of Otolaryngology, The University of Arizona, Tucson; and §The University of Arizona Cancer Center and The University of Arizona Bio5 Institute, Tucson, Arizona, U.S.A.

Objective: Untreated cutaneous malignancies involving the lateral aspect of the cranium often invade the temporal bone, necessitating a resection of this site. The reconstruction of the associated complex defect typically requires a reconstructive flap placement to obliterate the resection cavity and provide an aesthetically pleasing restoration. We performed a retrospective case review of 30 patients undergoing temporal bone resection and reconstruction with a submental island flap (SIF), free flap, or temporalis rotation flap.
