Surgical Treatments on Patients with Anterior Cervical Hyperostosis-Derived Dysphagia

Anterior cervical hyperostosis may be a cause of dysphagia. For anterior cervical hyperostosis, medical or surgical treatments can be adhibited in view of the causative mechanisms and intensities of dysphagia. We report 3 cases of cervical hyperostosis-derived progressive dysphagia that underwent operation. Radiologic diagnosis and Video Fluoroscopic Swallowing Study were performed on the three patients for evaluation. One had history of recurrent aspiration pneumonia accompanied by weight loss, another complained of dysphagia only when swallowing pills, and the third experienced recurrence symptom with reossification. All patients reported gradual improvement of dysphagia immediately after their cervical osteophytes were resected through the anterior approach. In relation to postoperative improvement, however, they expressed different degrees of satisfaction according to severity of symptoms. Surgical treatment, performed for the anterior cervical hyperostosis-derived dysphagia, can immediately relieve symptoms of difficulty in swallowing. This might especially be considered as an appropriate treatment option for severe dysphagia.

Comparison of Maternal Serum Screening Test Efficacy for Down Syndrome / 대한산부인과학회잡지

Maternal serum alpha-feto protein(MSAFP) screening test has provided high sensitivity and specificity in detecting neural tube defects(NTD). Approximately 80~90% of NTD can be identified by this screening test.Prospective studies have shown that low levels of MSAFP can be used for Down syndrome screening test, but the detection rate for Down syndrome in combination with age is only 20% in younger women, making this screening test relatively insensitive. However recently some studies have suggested that the triple marker test with MSAFP, unconjugated estriol, beta-human chorionic gonadotropin achieved higher detection rate for Down syndrome. The purpose of present study is to compare the positive predictive values of both MSAFP and Triple test. We had 6,436 cases of MSAFP test during the year of 1994 and 7,077 cases for triple test during the year of 1995. We analyzed data with positive results by screening both tests, since our purpose is to compare positive value. The number of positive results were 290(triple test) and 206(AFP) respectively. With this study, we concluded that positive predictive value of triple marker test is 4.17 times greater than of the MSAP test.
