To assess the effectiveness of Magnetic Resonance Imaging (MRI) with endorectal surface coil in the ataging of carcinoma of the uterine cervix with emphasis on parametrial involvement. Thirty women with clinically and radiographically proven carcinoma of the uterine cervix were initially included for this study, but thirteen patients were excluded since the stages of tumors wore beyond stage IIa. CT and MR findings of the remaining seventeen patients were performed at Cheil General Hospital and compared a1ong with clinical findings with the special emphasis on the parametrial involvement by the tumor. Staging was assessed by CT and MRI, and the results were compared with the pathologic staging. Radiea1 abdominal hysterectomy with the pelvic and paraaortic lymphnode dissection was done to all sewenteen patients. The staging made primarily by CT and MRI was either stsge 1 or Ila, but MR images with endorectal surface coil was superior to CT in the visualization of depth of tumor infiltration, especially parametrial involvement. The determination of the depth of the tumor made by MR images showed statistically significant correlation with histologic evaluation(R =0.768, p<0.01). The accuracy rate for the evaluation of the parametrial invo1vement was 82.3% far CT and 94.1% for MRI with endorectal surface coil. The overall accuracy rate for tumor staging was 70.5% for clinical, 58.8% for CT and 82.3% for MR evaluation. The accurecy rate in evaluation of the pelvic and paraaortic lymphnode was 88.2% for CT, but the evaluation done by MRl was not adequate due to small FOV(field of view). In assessment of The steging of careinoma of the uterine cervlx, MR images with endorectal surface coil was superior to CT, especially in the evaluation of the parametrial involvement.

The purpose of this study was to compare the effect of the hemostatic agent containing aluminum chloride with hemostatic agent containing ferric sulfate on the shear bond strength of resin-modified glass ionomer cement(RMGIC) to dentin in primary tooth.
Twenty extracted non-carious human primary teeth were collected in this study. The specimens were cut to expose dentin and polished. The specimens were randomly seperated into 3 groups for treatment; group I: polyacrylic acid(PAA), RMGIC; group II: aluminum chloride, PAA, RMGIC; group III: ferric sulfate, PAA, RMGIC
Ten specimens from each group were subjected to shear bond strength test.
The mean shear bond strength of each group was as follows: 10.07 ± 1.83 MPa in Group I, 7.62 ± 0.78 MPA in group II, 5.23 ± 0.78 MPa in group III. There were significant differences among all groups(p < 0.001).
In conclusion, both aluminum chloride hemostatic agent and ferric sulfate hemostatic agent decreased the shear bond strength of RMGIC to dentin. And ferric sulfate hemostatic agent decreased the shear bond strength of RMGIC more than the aluminium chloride hemostatic agent.

Cholangiocarcinoma is a form of adenocarcinoma arising from the intrahepatic or extrahepatic biliary epithelium. Apparent predisposing factors include some chronic hepatobiliary parasitic infsttations, congenital anomalies with ectatic ducts, sclerosing cholangitis and chronic ulcerative colitis and occupational exposure to possible biliary tract carcinogens. Patients with cholangiocarcinoma usually present with biliary obstruction, painless jaundice, pruritus, weight loss and acholic stools. Because the obstructing process is gradua1, the cholangiocarcinoma is often far advanced by the time it presents clinically. The diagnosis is most frequently made by cholangiography following ultrasound demonstration of dilated intrahepatic bile ducts. We report a case of common bile duct cancer spreading to gallbladder and common hepatic duct along the biliary mucosal epitherium and submucosal tissue in 68-year-old female patient along with a review of literature.

Medullar respiratory centers are composed of ventral and dorsal groups. A direct infarction to their structure could lead to a complete loss of respiratory drive, despite unilateral brainstem lesion is rarely associated with central respiratory dysfunction. A 70-year-old man was admitted with sudden dizziness and disequilibrium without motor weakness. Brain MRI (diffuse weight image) shows high signals intensities on left PICA territory of cerebellum and medulla oblongata including reticular formation, nucleus of tractus solitarius, nucleus ambiguus, and nucleus retroambiguus but sparing corticospinal and corticobulbar pathway. On 3rd hospital day, he had a complete loss of respiratory drive involving both autonomic and voluntary components. He didn't get the respiratory drive during CO2 retention while his consciousness and motor power were preserved.

Purpose: This study aimed to evaluate the long-term prognosis of contralateral central neck dissection (CND) in papillary thyroid cancer (PTC) patients with ipsilateral lateral neck metastasis. We compared the actual recurrence rate according to the extent of CND-ipsilateral and contralateral sides. Methods: A total of 708 PTC patients who underwent total thyroidectomy and concomitant ipsilateral or bilateral CND with ipsilateral lateral neck dissection between January 1997 and December 2022 at Samsung Medical Center were retrospectively analyzed. Results: The median follow-up time was 118 months. Locoregional recurrence was observed in 26 patients (7.9%) and 30 patients (7.9%) in the ipsilateral and bilateral CND groups, respectively. There were 6 contralateral recurrence cases (1.8%) in the ipsilateral CND group and 6 cases (1.6%) in the bilateral CND group. There was only 1 contralateral central neck recurrence in the ipsilateral CND group. The incidence of hypocalcemia (P = 0.007) was higher in the bilateral CND group compared to the ipsilateral CND group. Conclusion Surgeons may consider performing only unilateral CND-the side where tumor is for therapeutic purposes to reduce surgical complications.
