Human papillomavirus (HPV), particularly HPV16 and HPV18, can cause cancers in diverse anatomical sites, including the anogenital and oropharyngeal (throat) regions. Therefore, development of safe and clinically effective therapeutic vaccines is an important goal. Herein, we show that a recombinant fusion protein of a humanized antibody to CD40 fused to HPV16.

The resultant deformity frequently requires a three-dimensional reconstruction of bone and soft-tissue. The fibula free flap is the preferred method of reconstruction, with various modifications focused on providing supplemental soft-tissue coverage.
View Article and Find Full Text PDFObjectives: To gather preliminary data concerning the feasibility of using seven salivary mRNAs-IL-8; IL-1β; dual specificity phosphatase 1 (DUSP1); H3 histone family 3A (H3F3A); ornithin decarboxylase antizyme 1 (OAZ1); S100 calcium-binding protein P (S100P); and spermidine/spermine N1-acetyltransferase 1 (SAT1)-for detecting development of oral squamous cell carcinoma (OSCC) in oral lichen planus (OLP) patients and OSCC patients whose disease was in remission.
Materials And Methods: Saliva samples were collected from five study groups (25 subjects/group): newly diagnosed OSCC, OSCC-in-remission, disease-active OLP, disease-inactive OLP, and normal controls. The salivary mRNA levels were determined by a pre-amplification RT-qPCR approach with nested gene-specific primers.
Endothelin-1 (ET-1) is a potent vasoconstrictor involved not only in vascular biology but also in carcinogenesis. Results of a study in 2007 suggested salivary ET-1 as a potential biomarker for oral squamous cell carcinoma (OSCC), but a later study showed conflicting results. The purpose of our pilot study was to investigate feasibility of using salivary ET-1 as a biomarker for OSCC in two groups: oral lichen planus (OLP) patients and patients with OSCC in remission.

Methods: We searched operative case logs for all patients with thyroid carcinoma treated with an elective superior mediastinal dissection by the senior author (Y.
Background: To evaluate the efficacy of fluorine-18-fluorodeoxyglucose emission tomography (FDG-PET) and CT versus endoscopy with biopsy under general anesthesia for estimating tumor volume reduction among patients treated with induction chemotherapy for advanced squamous cell carcinoma (SCC) of the oropharynx.
Methods: Twelve patients with oropharyngeal SCC nested in a phase II, induction chemoradiation, organ preservation trial (University of Michigan Cancer Center 9921) underwent tumor volume reduction estimation as assessed by FDG-PET, CT, and endoscopy with biopsy.
Results: In 9 of 12 patients, FDG-PET, CT, and endoscopy demonstrated agreement in estimation of tumor reduction.
Objectives: To evaluate and describe retrograde endoscopic dilation of 100% strictures of the cervical esophagus and hypopharynx.
Methods And Materials: All patients who presented to the senior author (Y.D.

Study Design: Case series
Setting: Tertiary children's hospital.
Patients: Forty-three admissions diagnosed with SPOA by clinical presentation and contrast enhanced computed tomography (CECT) were retrospectively reviewed.
Objectives: To present our early experience with the transoral approach to the superomedial parapharyngeal space (PPS) and describe our technique for removal of these neoplasms.

Objective: To describe and evaluate the efficacy of frozen-section analysis of cortical bone margins in surgery of the craniofacial skeleton.
Study Design: Retrospective analysis of a consecutive series of patients undergoing oncologic resection of various head and neck neoplasms with osseous involvement by the senior author (Y.D.
Objectives: To evaluate the long-term efficacy of hydroxyapatite cement in craniofacial reconstruction, specifically examining the role (if any) of radiation, implant location, and cement type.
Study Design: A retrospective chart review was conducted of all patients presenting to the senior surgeon (Y.D.
Objectives: To present our experience with reconstruction of midfacial defects using "precontoured positioning plates" with or without pericranial flaps and to describe our technique in detail.
Methods: Thirty-two consecutive patients with midfacial defects subsequent to oncologic resection that were reconstructed primarily with cranial bone grafts and precontoured positioning plates were reviewed for type of defect, functional outcome, complications, and postoperative appearance.
Results: Primary reconstruction of all defects in this series was performed.

Objective: To present our experience with fibula-free tissue transfer in patients with documented 2-vessel runoff to the lower extremity on preoperative angiography.
Methods: A case series of 16 patients with segmental mandibular defects reconstructed with a fibula-free flap by the senior author with 100% stenosis of the anterior or posterior tibial arteries were retrospectively reviewed for radiographic data and complications.
Results: All flaps performed were successful, and there were no donor site complications.
Objective: To review the demographic, microbiologic, and outcome data for children with complications of acute sinusitis.
Study Design And Setting: Retrospective review of children admitted with complications of acute sinusitis from January 1995 to July 2002 to a tertiary care children's hospital.
Results: One hundred four patients were reviewed with the following complications: orbital cellulitis (51), orbital abscesses (44), epidural empyemas (7), subdural empyemas (6), intracerebral abscesses (2), meningitis (2), cavernous sinus thrombosis (1), and Pott's puffy tumors (3).

Paranasal sinus malignancies are challenging to treat. Most patients present with advanced lesions, often with intracranial or intraorbital extension, and have a poor overall prognosis. Given the low incidence and diverse pathologies of paranasal sinus cancers, it is extremely difficult to perform prospective, randomized clinical trials to compare different treatment approaches.
