PURPOSE: To determine both the efficacy and safety of the topical application of 50 mg penicillin G potassium troches (Cankercillin) in the treatment of minor recurrent aphthous stomatitis (RAS). STUDY DESIGN: The investigation used a phase 2 double-blind, randomized placebo-controlled trial with a no-treatment arm. Subjects with minor aphthous ulcers of duration <48 hours were followed for 1 week. The primary endpoint for efficacy was time (days) to complete ulcer resolution, and the secondary endpoint was time (days) to complete pain relief. RESULTS: Thirty-one, 33, and 36 subjects were randomized to the active treatment, placebo, and no-treatment arms, respectively. Baseline findings were heterogeneous across arms. Subjects who received penicillin G treatment had complete ulcer healing and pain relief significantly earlier than those in the placebo and no-treatment arms. No allergic reactions were observed. CONCLUSIONS: Topical penicillin G, by mechanisms which remain unclear, reduces the time of healing and pain relief of minor aphthous ulcers with minimal safety concerns. Larger phase 3 studies are necessary to confirm these findings

The importance of the care given by the pediatric otolaryngologist to the individual child encompasses the traditional purposes of medicine. This field has its special focus on interventions that preserve, restore and/or otherwise improve hearing, speech, voice, gustation, olfaction, deglutition, respiration, appearances, etc. The value-added dimension of pediatric otolaryngology is of essential importance because it enhances communication-language--through the vehicles of hearing, voice, and speech. This critical role is manifest in two ways. The first relates to the economic bases of society. Comparison of the consequences of communications disorders in three different countries ranging, currently, from one very highly dependent upon communication skills (The Netherlands), to one highly dependent upon communication skills (the United States), to a developing nation less dependent upon communication skills (the Philippines) is presented. All three nations are adversely affected economically and socially by communication disorders. It is estimated that the United States loses between 2.5 and 3% of its gross domestic product from the economic sequel of communication disorders. It also appears that communication disorders contribute to crime, since the prevalence of communication disorders is many times greater in populations of juvenile delinquents than in the general population. Communication disorders may act synergistically with diminished economic and social resources and other factors in the causes of violent behavior and crime.

Locoregional recurrence remains a major obstacle to achieving cure of locally advanced head and neck cancers despite maximal resection and postoperative external beam radiation therapy (EBRT). Locoregional failure occurs in 30% to 40% of high-risk resected head and neck cancer patients after standard postoperative EBRT. In an effort to overcome this problem, a number of strategies have been designed to enhance the effectiveness of radiation including concurrent postoperative chemoradiation, accelerated radiation schedules, incorporation of targeted biologic therapies, and improved radiation delivery techniques such as intensity modulated radiation and high-dose rate (HDR) intraoperative radiation therapy. Intraoperative radiation therapy (IORT) represents an important approach to improve outcome in head and neck cancer patients treated with definitive surgery. High-dose rate IORT is defined as the delivery of a single, large dose of radiation at the time of surgery when the tumor bed is exposed. In conjunction with EBRT, HDR-IORT offers several advantages including: (1) conformal delivery of a large dose of radiation while the tumor bed is precisely defined, minimizing the risk of a geographic miss; (2) potential for subsequent dose reduction of EBRT; (3) shortening overall treatment time; and (4) dose-escalation. Because mucositis represents the dose-limiting acute toxicity and xerostomia ranks as the most common long-term quality-of-life complaint, a reduction of the EBRT dose may provide an important benefit in reducing toxicity, especially when combined with the radioprotectant amifostine (Ethyol, WR-2721; MedImmune, Inc, Gaithersburg, MD). The purpose of this article is to review the rationale for integrating HDR-IORT with a reduced dose of postoperative EBRT combined with amifostine to improve locoregional control and quality of life outcomes in advanced-stage resected head and neck cancer patients.

The current study sought to determine whether shifts in key components of the inflammatory process could be detected from laryngeal secretions sampled before and after vocal loading. A healthy 44-year-old woman served as the subject. The vocal folds were swabbed to collect baseline secretions. Ten and 20 minutes after nearly constant loud phonation for 1 hour, the vocal folds were swabbed again. The findings indicated strong shifts in several key inflammatory mediators: interleukin-1beta, tumor necrosis factor alpha, and matrix metalloproteinase 8. The concentrations of those mediators continued to increase from the 10- to 20-minute postloading time-points. Transforming growth factor beta and prostaglandin E2 did not demonstrate clear shifts. In summary, mediators reflecting the acute inflammatory process could be detected from laryngeal secretions in an awake human. The upward slope of the curves at the 20-minute time interval indicates the need for longer follow-up sampling to determine the full biological response of the vocal folds to acute phonotrauma

The professional journal promotes and sustains academic departments through several mechanisms that include peer review, editing, timing, and solicitation of works. The ways in which peer review strengthens and augments academic pediatric otolaryngology are through: the creation of new knowledge; knowledge transfer-teaching; the establishment and development of quality medical/surgical standards; scholarship; and the fostering of the development of the next generation of academic physicians is detailed.

BACKGROUND: Head and neck cancer patients treated with chemoradiation have difficulty eating a normal diet. This study was designed to characterize eating ability over 12 months after chemoradiation treatment. Analyses take patient dropout into account. METHODS: Two hundred fifty-five patients with head and neck cancer treated with chemoradiation were followed for 12 months. Eating ability was analyzed using generalized linear model methods that accounted for non-ignorable dropout. RESULTS: Eating ability was compromised immediately after treatment and improved over 12 months to near pretreatment levels. Ability to eat at most 50% of the diet orally did not return to baseline levels (p <.05). However, the percent of patients eating a normal diet did return to baseline levels. Accounting for dropout modified the results, but the pattern of significance was similar. CONCLUSIONS: Treatment of head and neck cancer with chemoradiation has a significant effect on eating ability, which improves after 12 months after treatment

The pediatric otolaryngologist cares for children who have abnormal language as a primary or secondary deficiency. Five children, each with a different form of language disorder, are presented. These are children with specific language impairment (SLI) expressive, pervasive developmental delay (autism), expressive language delay associated with severe to profound hearing loss early in life, language delay secondary to a moderate to severe hearing loss diagnosed late and not cared for, and language delay secondary delay secondary to social deprivation and otitis media with effusion.

Fanconi anemia is an autosomal recessive disorder characterized by congenital malformations, bone marrow failure, and the development of squamous cell carcinomas (SCCs) and other cancers. Recent clinicopathologic evidence has raised the possibility that an environmental factor such as human papillomavirus (HPV) may be involved in the pathogenesis of SCCs in Fanconi anemia patients. Given the high prevalence of p53 mutations in SCCs among the general population and the lack of p53 mutations in HPV-related carcinogenesis, we evaluated the role of HPV and p53 mutations and polymorphisms in SCC from Fanconi anemia patients. We used polymerase chain reaction (PCR) screening and real-time PCR to detect and quantify HPV DNA in DNA extracted from microdissected SCCs obtained from 24 Fanconi anemia patients (n = 25 SCCs; case subjects) and 50 age-, sex-, and tumor site-matched SCC patients without Fanconi anemia (n = 50 SCCs; control subjects). We PCR-amplified and sequenced exons 4-9 of the p53 gene from SCC DNA. We detected HPV DNA in 84% of the SCC specimens from the case subjects and in 36% of the SCC specimens from the control subjects (P<.001). The prevalence of p53 mutations in SCCs from the case subjects (0%, 0/25) was statistically significantly lower than that of SCCs from the control subjects (36%, 12/33; P<.001). A greater proportion of patients with Fanconi anemia and SCC were homozygous for Arg72, a p53 polymorphism that may be associated with increased risk for HPV-associated human malignancies, than an ethnically-matched cohort of Fanconi anemia patients without SCC (75% versus 51%; P =.05). These data suggest that Fanconi anemia is associated with increased susceptibility to HPV-induced carcinogenesis

Botulinum toxin (Botox) has firmly established itself as one of the premier nonsurgical therapies. Recently, Botox is also being used as an adjuvant to many aesthetic procedures, both surgical and nonsurgical. This combined therapeutic use for Botox may not only create an added benefit toward facial rejuvenation but may create a synergistic one as well. This article examines such uses for Botox and reviews the current medical literature.

The nasolabial flap is a straightforward and time-tested reconstructive option suitable for a variety of facial and oral defects. The superiorly and inferiorly based variants are well described in the literature and offer a rapid and reliable alternative to time-consuming microvascular free flaps and less esthetic skin grafts. Despite newer and more complex alternatives, the nasolabial flap maintains its prominent position in the reconstructive armamentarium of the oral and maxillofacial surgeon
