OBJECTIVE: The object of this study was to compare the diagnostic accuracy of a sonographic morphologic scoting system, the serum CA-125 assay, and a combination of both in patients undergoing laparotomy for a clinically diagnosed adnexal mass. METHODS: In 129 consecutive patients, the morphology of the mass was evaluated and scored by the morphologic scoring system of Sassones using transabdominal or transvaginal sonography and blood samples were obtained for CA-125 assay before planning surgery, RESULTS: The sensitivity of the sonographic morphologic scoring system was 90.6%, the specificity 84.5%, the positive predictive value 65.9%, and the negative predictive value 96.5%, compared with 68.8, 77.3, 50.0, and 88.2% for CA-125 and 96.9, 66.0, 48.4, and 98.5% for the two tests combined, respectively. Only one case of serous borderline ovarian tumor was missed when the two tests were combined. The sensitivity and mean value of the serum CA-125 increased with the stage of ovarian cancer. CONCLUSION: The combination of sonographic findings with a serum CA-125 assay was more sensitive, but less specific, than sonography or the serum CA-125 assay alone in predicting the malignancy of an adnexal mass. The serum CA-125 level generally reflected the stage of the disease. We think that it is reasonable to check the serum CA-125 only in cases of ovarian malignancy diagnosed by sonography.

BACKGROUND: Cardiac myxomas are rare benign tumors of the heart. Although cardiac myxomas are histologically benign, they may be lethal because of their strategic position. Most cases are sporadic, but rare familial occurrence has been described. PATIENTS AND RESULTS: The left atrial myxoma with cerebral embolism was diagnosed in the 21 year old female and the left atrial myxoma with acromegaly due to pituirary adenoma was subsequently diagnosed in her 19 year old male sibling. The myxoma in the male patient was successfully excised. CONCLUSION: Echocardiography can be used effectively in the diagnosis of atrial myxoma, detection of its possible recurrence, and screening other members of the family.

This study was aimed for comparison of efficacy in detecting epileptiform discharges, which was originating from mesiobasal temporal lobe, among the four non-standard non-mvasive skm surface electrodes such as ear lobe(Al/A2), zygomatic(Zl/Z2), surface sphenoidal(SS1/SS2) and true anterior temporal electrode(Tl/T2). The study was performed with simultaneous placement of the nonstandard electrodes including standard electrodes(F7/F8). The resul ts were as follows. Among the non-standard electrodes, zygomatic and true anterior temporal electrodes detected more epileptiform discharges compared to the other two electrodes, although there was no statistical significancy. Compared to the standard electrodes, zygomatic and true anterior temporal electrode showed statistically high significant detecting rate (p<0. 01). Also average detection rate of epileptiform discharges of the whole non-standard electrodes which was compared to the rate of the standard electrodes showed statistically significance (p<0.05). In conclusions, non-standard surface electrodes, especially zygomatic and true anterior temporal electrode, are considered as valuable to detect the epileptiform discharges from temporal lobe if they were used at the routine initial EEG examination.

BACKGROUND: Paradoxical embolism through the patent foramen ovale (PFO) is a well-recognized mechanism for otherwise unexplained ischemic stroke. Although transthoracic contrast echocardiography (TCE) has been used frequently for noninvasive diagnosis of right to left shunt through PFO, its diagnostic accuracy appears limited, especially in patients with poor acoustic window. Since harmonic imaging (HI) can enhance the definition of contrast microbubbles, theoretical advantages of HI in the detection of right to left shunt through PFO using microbubbles can be considered. However, there are few data regarding the diagnostic efficacy of HI in the detection of right to left shunt through PFO. The purpose of this study was to compare the diagnostic value of transthoracic HI in the detection of right to left shunt through PFO in patients with stroke with that of fundamental imaging (FI). Methods: One hundred thirty-six consecutive patients with stroke (82 male, mean age:9) underwent TCE in both HI and FI and transesophageal echocardiography (TEE) during rest and Valsalva maneuver with intravenous administration of agitated saline. PFO was judged to be present if microbubbles appeared in the left atrium within 3 cardiac cycles of their appearance in the right atrium. TEE was regarded as the gold standard for assessing the diagnostic accuracy of TCE. Results: Right to left shunt through PFO was detected in 40 of 136 patients by TEE (29.4%). FI of TCE detected shunt through PFO in only 9 of 136 patients (6.6%). In contrast, HI detected shunt through PFO in 25 of 136 patients (18.4%). The overall sensitivity and specificity of FI and HI for detection of right to left shunt through PFO were 22.5%, 62.5% (p<0.05) and 100%, 100%, respectively. Valsalva maneuver during HI significantly increased the detection rate of shunt through PFO (during rest in 9 and during Valsalva maneuver in 25, p<0.05). CONCLUSION: HI with contrast microbubble injection significantly enhanced the detection of right to left shunt through PFO in patients with ischemic stroke compared with FI by transthoracic approach.

Posttraumatic syringomyelia may result from a variety of inherent conditions and traumatic events, or from some combination of these. Many hypotheses have arisen to explain this complex disorder, but no consensus has emerged. A 28-year-old man presented with progressive lower extremity weakness, spasticity, and decreased sensation below the T4 dermatome five years after an initial trauma. Magnetic resonance imaging (MRI) revealed a large, multi-septate syrinx cavity extending from C5 to L1, with a retropulsed bony fragment of L2. We performed an L2 corpectomy, L1-L3 interbody fusion using a mesh cage and screw fixation, and a wide decompression and release of the ventral portion of the spinal cord with an operating microscope. The patient showed complete resolution of his neurological symptoms, including the bilateral leg weakness and dysesthesia. Postoperative MRI confirmed the collapse of the syrinx and restoration of subarachnoid cerebrospinal fluid (CSF) flow. These findings indicate a good correlation between syrinx collapse and symptomatic improvement. This case showed that syringomyelia may develop through obstruction of the subarachnoid CSF space by a bony fracture and kyphotic deformity. Ventral decompression of the obstructed subarachnoid space, with restoration of spinal alignment, effectively treated the spinal canal encroachment and post-traumatic syringomyelia.

BACKGROUND: It has been known that a patient head in sniffing position for lightwand facilitated tracheal intubation is not an anatomically appropriate method. However, there is no evidence nor study whether it is true or not. In this study, we compared success rates of lightwand facilitated tracheal intubation in neutral position versus sniffing position. METHODS: With informed consent, sixty adult patients of ASA physical status I or II were randomly allocated into two groups: neutral position (N) or sniffing position (S) group. A lightwand and tube were bent at approximately a 90degrees degree angle for N group and a 60 degree angle for S group on the basis of mouth axis and pharyngeal axis. The time to intubation, success rates of 1st trial of intubation, overall intubation success rates, hemodynamic changes and complications during the procedure were recorded. RESULTS: There was no significant difference in the time to intubation, success rates of 1st trial of intubation, overall intubation success rates, hemodynamic changes and complications between neutral position and sniffing position groups. CONCLUSIONS: Success rates of lightwand facilitated tracheal intubation in neutral position versus sniffing position showed no significant difference. Therefore, both positions are suitable for lightwand assisted intubation.

OBJECTIVES: The purpose of this study was to develop the Korean version of the Social Adjustment Scale II-Revised Version (KSAS II-RV) in the schizophrenics. METHODS: KSAS II-RV was administered to 67 schizophrenic patients and 78 matched normal controls for examining the reliability and validity. RESULTS: Data analysis showed statistically significant reliabilities and validities of KSAS II-RV. The test-retest reliability, inter-rater reliability, and internal consistency for total scores of KSAS II-RV were 0.85, 0.89. and 0.87, respectively. Evidence for discriminant validity of KSAS II-RV comes from the results that the mean scores of schizophrenic patients were significantly high than those of normal controls. Construct validity was assessed by calculating the 10 inter-subareas correlations of the KSAS II-RV, and all except the sexual adjustment area were statistically significant. Significant correlations between the global area scores of KSAS II-RV and those of Global Assessment of Functioning Scale lend support for the concurrent validity of this instrument indirectly. CONCLUSION: KSAS II-RV was found to be a valid and reliable instrument which can be used to evaluate the degree of social adjustment in the schizophrenic patients.

Spindle cell carcinoma is a rare variant of squamous cell carcinoma characterized histologically by a biphasic pattern with both squamous and spindle cell component. There is controversy in the histogenesis, biologic behavior, optimal treatment and prognostic factor for tumor. Treatment must be similar for squamous cell carcinoma. With a review of literature, we report a case of a 61-year-old male with spindle cell carcinoma in the larynx, which has been managed by wide excision of tumor and postoperative radiotherapy.

BACKGROUND AND OBJECTIVES : VEMP (Vestibular Evoked Myogenic Potential) has a pathway that runs the lower brainstem including the inferior vestibular nerve, vestibular nucleus and vestibulospinal tract. Therefore, VEMP may also show abnormal findings in patients with lesions in the central nerve system of the VEMP pathway. In this study, we compared results of VEMP among the normal and central vertigo patients. SUBJECTS AND METHOD : We compared the results of VEMP conducted in 14 healthy volunteers and 11 patients who had been diagnosed by brain MRI (magnetic resonance imaging)as having central vertigo with a lesion at the brainstem. The results of VEMP and caloric test are. RESULTS : The incidence of abnormal VEMP was about 73%. Of the parameters of VEMP, prolonged p13 latency was shown in all patients with abnormal VEMP. The caloric test revealed abnormal findings in 46% of the patients and all patients with abnormal caloric response had lesions at the pons. CONCLUSION : The VEMP was the method used to evaluate downward pathway of the lower brainstem and the prolonged p13 latency was thought as the most valuable parameter in the evaluation of brainstem. The patients with central vertigo that had the lesion at the pons might show the abnormal calroic response because of hypoperfusion to vestibular organ.
