We conducted a retrospective study to determine the incidence and treatment outcomes of neck metastases in patients with squamous cell carcinoma (SCC) of the hard palate and/or maxillary alveolus after surgical excision of the primary tumor. We also sought to identify any risk factors for recurrence. Our study population was made up of 20 patients-9 men and 11 women, aged 46 to 88 years (mean: 72.6)-who had undergone excision of an SCC of the hard palate and/or maxillary alveolus at a tertiary care cancer center over a 7-year period. Half of all patients were former tobacco users. Of the 20 tumors, 10 involved the maxillary alveolus, 4 involved the hard palate, and 6 involved both sites. Three patients were clinically categorized as T1, 9 as T2, 6 as T3, and 2 as T4; pathologically, 8 tumors were categorized as T4a. In addition to maxillectomy, a neck dissection was performed in 7 patients-4 therapeutically and 3 electively. Eight of 20 patients experienced a recurrence: 4 local, 6 regional, and 2 distant (several patients had a recurrence at more than one site). Univariate analysis identified perineural invasion (p = 0.04) as a statistically significant risk factor for recurrence. Of 14 patients with a clinicopathologically negative neck, 5 (36%) developed a cervical recurrence, and 4 of them died of their disease. An advanced stage (T4 vs. <T4) was not significantly correlated with the risk of regional metastasis (p = 0.58). The rate of occult nodal metastasis in clinically and radiologically N0 necks was high. Clinical and radiologic understaging was common, and regional recurrences frequently resulted in death. We conclude that elective nodal evaluation and treatment of the neck warrants strong consideration for most patients with cancer of the hard palate and/or maxillary alveolus.

Posterior epistaxis: Common bleeding sites and prophylactic electrocoagulation

October 25, 2016  |  Juan Liu, MD; Xicai Sun, MD; Limin Guo, MD; Dehui Wang, MD


Posterior epistaxis is a frequent emergency, and the key to efficient management is identification of the bleeding point. We performed a retrospective study of 318 patients with posterior epistaxis treated with endoscopic bipolar electrocautery during a 4-year period. Distribution of the bleeding sites was recorded. Patients with no definite bleeding sites in the first operation were assigned to Group A (n = 39) and Group B (n = 34). Patients in Group A were only observed in the ward. Patients in Group B were given prophylactic electrocoagulation at the common bleeding points. Of the 318 patients, bleeding sites were successfully identified and coagulated in 263 patients. All of them were located posteriorly, with 166 on the lateral nasal wall, 86 on the septum, and 11 on the anterior face of the sphenoid sinus. The rebleeding rate of Group B (8.8%) was lower than that of Group A (38.5%) (p < 0.01).

Chronic otitis media with effusion following radiation therapy

The incidence of chronic otitis media with effusion (COME) after radiotherapy for nasopharyngeal or sinonasal tumors is relatively high. It is often a difficult-to-treat problem in these patients. In this retrospective study, we sought to describe the clinical course of COME in 51 patients-33 men and 18 women, aged 39 to 90 years (mean: 58.9 ± 15)-who had been referred to the Henry Ford Health System in Detroit between 2001 and 2011 for management of a tumor that had involved either the nasopharyngeal area or the sinonasal area. The median length of follow-up from the time of cancer diagnosis was 32 months. Of the 51 patients, 23 (45.1%) developed COME before, during, or after radiation therapy. Of these 23 patients, 13 (56.5%) did not experience any improvement after treatment with various combinations of therapies, including myringotomy, tympanostomy tube placement, otic drops, oral antibiotics, and corticosteroid nasal sprays. No patient- or tumor-specific factors were found to be significantly associated with the incidence of COME after irradiation to the sinonasal area. Older age and squamous cell tumor pathology were found to be significant factors for the resolution of COME after it had developed, whereas treatments with tympanostomy tubes and ear drops were not. Because of the high incidence of COME after radiotherapy and the high rate of COME's failure to resolve after tympanostomy tube insertion, we suggest that these patients require an alternative treatment.

On first appearance, angiosarcomas can be mistaken for benign lesions, such as cellulitis, hemangioma, rosacea, and rhinophyma.

Changes in antibiotic resistance in recurrent Pseudomonas aeruginosa infections of chronic suppurative otitis media

This study investigated the changes in antibiotic resistance in recurrent Pseudomonas aeruginosa infections in chronic suppurative otitis media (CSOM). Its aim was to provide a treatment strategy for P aeruginosa infections in CSOM for the prevention of multidrug resistance. A case-control study was conducted in tertiary teaching hospitals in Korea. The experimental group included patients with recurrent P aeruginosa infection who had relapsed within 2 months after the successful control of a previous P aeruginosa infection. The control group consisted of patients with a P aeruginosa infection who had no history of such an infection. An antibiotic sensitivity test was performed for each culture. The proportion of recurrent P aeruginosa infection was 22.69% (98 of 432 cases). Drug resistance to amikacin, tobramycin, netilmicin, ciprofloxacin, and levofloxacin was significantly changed after recurrent infection. The fluoroquinolone strains seen in recurrent P aeruginosa showed high cross-resistance to other drugs. Antibiotic resistance of P aeruginosa in CSOM changed with recurrent infection.

Evaluation of transiently evoked otoacoustic emissions and auditory brainstem responses in patients with multiple sclerosis

Multiple sclerosis (MS) is an inflammatory and demyelinating disease of the central nervous system. This prospective study was planned to evaluate these changes through brainstem evoked response audiometry (BERA) latency abnormalities and otoacoustic emissions (OAE). This study was performed between September 2009 and May 2010. A total of 160 recordings of BERA and OAE were examined, which were obtained from 80 ears of 40 participants. Twenty of these were MS patients and 20 were healthy volunteers in the control group. Mean ages of the MS group and the control group were 31.3 ± 4.73 and 30.95 ± 4.83 years, respectively. In patients' right ears in the MS group, the wave I, III, and V peak latencies and the I-V interpeak latencies were significantly prolonged compared to those in the control group. In patients' left ears in the MS group, the wave I, III, and V peak latencies and the I-III and I-V interpeak latencies also were significantly prolonged compared to those in the control group. There were no significant differences between the right and left ears for each group regarding wave latencies and intervals. In the MS group, the average of the interaural difference for I-V interpeak latency was significantly prolonged compared to that in the control group. The most reliable diagnostic method in MS is magnetic resonance imaging (MRI). However, sometimes plaques in the central nervous system may not be displayed. The pathologic process may exist and continue before these plaques become detectable on MRI, but electrophysiologic testing such as BERA can demonstrate these changes.

Bullous pemphigoid is an autoimmune bullous disease characterized by skin lesions, with or without oral lesions. The occurrence of pharyngolaryngeal lesions is very rare in affected patients. We conducted a study to investigate the characteristics of oral and pharyngolaryngeal lesions in bullous pemphigoid. Our study population was made up of 6 consecutively presenting outpatients-2 men and 4 women, aged 40 to 83 years (mean: 68.2)-who had been referred to our department over an 11-year period. Presenting symptoms included sore throat in all 6 patients and oral pain in 3. The sites of mucosal lesions included the soft palate, epiglottis, gingiva, hypopharynx, tongue, nasal cavity, and buccal mucosa. These lesions appeared as erosions, erosions with white coating, erythematous patches, and/or blisters. Mucosal lesions preceded skin lesions in 2 patients, appeared after skin lesions in 1 patient, and appeared simultaneously with skin lesions in 3 patients. We conclude that bullous pemphigoid sometimes involves the mucosa, such as that of the laryngopharynx and the oral cavity, and it can manifest as skin lesions. In the differential diagnosis of refractory pharyngolaryngeal lesions, bullous pemphigoid should be considered.
