Respiratory epithelial adenomatoid hamartoma: a case report.

Respiratory epithelial adenomatoid (READ) hamartoma is a recently described entity characterized by abnormal glandular formations arising from the epithelium of the nasal cavity. The etiology of the lesion is unclear and may be secondary to either sinonasal inflammation or developmental error. We present a case of a 54-year-old man with a unilateral nasal mass found to be consistent with READ hamartoma upon pathologic review. Although READ hamartomas are thought to be rare, awareness of the lesion is important since it may be confused with sinonasal adenocarcinoma, leading to overly aggressive treatment. Therefore, READ hamartoma should be included in the differential diagnosis of a unilateral nasal mass.

Research subject privacy protection in otolaryngology.

BACKGROUND: Health Insurance Portability and Accountability Act regulations, which took effect on April 14, 2003, placed new constraints on the use of protected health information for research purposes. OBJECTIVE: To review practices of research subject privacy protection in otolaryngology in order to determine steps necessary to achieve compliance with Health Insurance Portability and Accountability Act regulations. STUDY DESIGN: Literature review. METHODS: Articles appearing in 2001 in 3 widely circulated otolaryngology journals were classified according to study design. The "Methods" section of each article was reviewed to determine whether the informed consent and institutional review board processes were clearly documented. RESULTS: Descriptive studies involving case reports and case series were more common than observational studies that include a control group (66% vs 11%). Few case series documented the consent process (18%) and institutional review board process (19%). Observational designs demonstrated better documentation of the consent process (P<.001) and the institutional review board exemption and approval process (P<.001). CONCLUSIONS: Methods used to protect subject privacy are not commonly documented in case series in otolaryngology. More attention needs to be given to research subject privacy concerns in the otolaryngology literature in order to comply with Health Insurance Portability and Accountability Act regulations.

Anaphylaxis.

Anaphylaxis is an amplified, harmful immunologic reaction that occurs after re-exposure to an antigen to which an organism has become sensitive. True anaphylaxis is a systemic reaction caused by antigen-specific cross-linking of IgE molecules or complement proteins on the surface of tissue mast cells and peripheral blood basophils, resulting in the immediate release of potent mediators. Immediate systemic reactions that resemble anaphylaxis but are not caused by an IgE-mediated immune response are referred to as anaphylactoid reactions. It is important for physicians, especially those who treat allergies, to understand the pathophysiology, know the treatment for, and recognize the clinical signs of anaphylaxis.

Pericranial flap for closure of paramedian anterior skull base defects.

OBJECTIVE: We sought to examine the position of a pericranial flap reconstruction of anterior skull base defects with respect to the original floor of the anterior cranial fossa. STUDY DESIGN: A retrospective chart and radiology review of 17 patients (1993-2001) with pericranial flap reconstruction for anterior skull base defects and 17 controls was performed. RESULTS: At 6 or more months after surgery, the new positions of the pericranial flaps ranged from 5 mm above to 11.3 mm below the positions of the original cribriform plates. There were no complications related to the pericranial flaps such as hemorrhage, flap loss, or brain herniation except for 2 (11.8%) cerebrospinal fluid leaks, 1 of which required operative correction. CONCLUSION: Pericranial flap reconstruction is a reliable method with low morbidity for closure of the most common skull base defect from the craniofacial resection that entails removal-unilateral or bilateral-of the fovea ethmoidalis, cribriform plate, and/or superior septum. This flap creates a watertight seal between the extradural space and the nasal cavity, prevents clinically significant brain herniation, and is associated with a low rate of cerebrospinal fluid leakage even without postoperative lumbar subarachnoid drainage of the cerebrospinal fluid.
