Cholesteatoma can develop in very young children with congenital aural stenosis and a duplication anomaly, and physicians should consider this condition in affected children with otalgia and otorrhea.
Congenital aural stenosis is defined as an external auditory canal less than 4 mm across. Cholesteatoma is far more likely in a bony ear canal opening of 2 mm or less, but regardless of the degree of stenosis, the incidence of cholesteatoma is very low in patients younger than 3 years. Therefore, surgery is usually delayed until later in...
We conducted a study to evaluate the quality of guidelines for squamous cell carcinoma of the head and neck (SCCHN) with the exception of nasopharyngeal cancer. Electronic searches were conducted of the U.S. National Guideline Clearinghouse, the Canadian Medical Association Infobase, the Guidelines International Network, the Scottish Intercollegiate Guidelines Network, the China Biology Medicine disc, PubMed, and Embase. Two independent reviewers assessed the eligible guidelines using the Appraisal of Guidelines for Research and Evaluation II (AGREE II) instrument. The degree of agreement among these sources was evaluated by using the intraclass correlation coefficient (ICC). A total of 514 articles were found to be clinical-guideline-related, and 49 guidelines were included in our analysis. Scores were assigned for each of the AGREE II domains: scope and purpose (mean: 71.63% ± 2.80; median: 75%; ICC: 0.76), stakeholder involvement (mean: 43.37% ± 2.96; median: 50%; ICC: 0.93), rigor of development (mean: 45.63% ± 3.84; median: 42%; ICC: 0.83), clarity of presentation (mean: 68.08% ± 2.53; median: 72%; ICC: 0.85), applicability (mean: 32.41% ± 3.03; median: 29%; ICC: 0.92), and editorial independence (mean: 42.55% ± 4.57; median: 42%; ICC: 0.95). We considered a domain score of greater than 60% to represent an acceptable level of quality. We conclude that, overall, the quality of SCCHN guidelines is moderate in relation to international averages. Greater efforts are needed to provide high-quality guidelines that serve as a useful and reliable tool for clinical decision making in this field.
Head and neck cancer includes malignant tumors arising from a variety of sites in the upper aerodigestive tract, with squamous cell carcinoma being the most common histologic type. Squamous cell carcinoma of the head and neck (SCCHN) occurs in the oral cavity, oropharynx, hypopharynx, and larynx.1 SCCHN is the sixth most common...
Paranasal sinus mucoceles are epithelial-lined cystic lesions containing mucus or mucopurulent fluid. Symptoms vary depending on the location of the mucocele.
A 15-year-old boy was referred to our hospital with a headache in the right side of his head and nasal obstruction. Despite treatment with antibiotics and analgesics, he continued to experience persistent headaches and nasal obstruction. He reported no other health problems. Nasal endoscopy revealed a large amount of purulent nasal discharge in...
While it is true that individuals may have a preferred means of receiving information, there is no evidence that learners actually learn better when information is presented to them via their preferred method.
The notion that every learner has a particular “learning style” has been ingrained into the minds of most medical educators. This concept is based on the idea that people process information differently and suggests that learning is more likely to occur when instruction is tailored to an individual's learning style.
Acinic cell carcinoma accounts for approximately 2 to 6% of all salivary gland tumors. It usually originates in the parotid gland; the minor salivary glands and the upper respiratory tract are involved only infrequently. We describe a case of acinic cell carcinoma of the posterior wall of the pharynx in a 21-year-old woman. To the best of our knowledge, this is the first case of this type of carcinoma at this location to be published in the literature. The mass was excised, and the patient was referred for postoperative radiation therapy to reduce the risk of local recurrence, but she did not keep her appointment and was lost to follow-up.
Acinic cell carcinoma is an uncommon malignancy. When it occurs, it usually arises in the salivary glands; it accounts for approximately 2 to 6% of all salivary gland tumors.1 The most common salivary gland site is the parotid gland; involvement of the minor salivary glands is infrequent. Acinic cell carcinoma also can develop in the...
