A 22-year-old female presented with a cerebellopontine angle epidermoid tumor manifesting as a rare combination of hemifacial spasm, trigeminal neuralgia, and tinnitus. Magnetic resonance imaging demonstrated the tumor distorting the brainstem and the fourth ventricle. The tumor was almost completely resected and the seventh-eighth cranial nerve complex was decompressed by mobilizing the anterior inferior cerebellar artery loop. No arterial loop was related to the trigeminal nerve. The patient was completely relieved of the``tic convulsif'' and tinnitus after the surgery. The inflammatory nature of epidermoid tumor may be involved in the etiology of the syndrome. Microvascular decompression may be needed in addition to tumor removal in such cases.
SUMMARYA 45 year-old woman who presented with non-specific neck and shoulder pain, was found to have mild hypercalcaemia, markedly elevated parathyroid hormone levels, and an irregular parathyroid gland on imaging. The patient underwent a parathyroidectomy and the pathology report came back positive for parathyroid carcinoma with muscular invasion. Parathyroid carcinoma is an exceptionally rare cause of primary hyperparathyroidism and can have a poor prognosis due to metastases and a high propensity to recur after resection. Reports of non-functioning parathyroid carcinomas tend to behave even more aggressively. Repeat imaging on this patient showed residual cancer present, so the patient underwent a second surgery with radical neck dissection and has since been doing very well postoperatively. Diagnosis and treatment is challenging and it is critical to continuously follow-up for recurrent disease.
BACKGROUND
We conducted a prospective, preliminary study to compare the cost-effectiveness of two different instrument-based techniques for diagnosing and managing dysphagia in 30 consecutive hospitalized patients with head and neck cancer. The two techniques are videofluoroscopy via modified barium swallow (MBS) and videoendoscopy via flexible endoscopic evaluation of swallowing with sensory testing (FEESST). Medicare was the primary insurer of all patients. Fifteen of these patients had their dysphagia diagnosed and managed by MBS and the other 15 by FEESST. Cost-effectiveness was assessed by determining the average Medicare reimbursement for each procedure. We found that the mean reimbursements were $451.01 (± $50.55) for MBS and $321.23 (± $3.01) for FEESST. The mean reimbursement for FEESST was significantly lower than that for MBS (p< 0.0001; Mann-Whitney U test). We conclude that FEESST appears to be more cost-effective than MBS for the inpatient management of dysphagia in patients with head and neck cancer.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
