BACKGROUND: Esmolol is a short acting sympathetic beta receptor antagonist, and it was successfully applied to induced hypotension. Esmolol lowers blood pressure by decreasing cardiac output, and does not cause vasodilation. This property of esmolol may help to decrease bleeding during induced hypotension. In this study, we tried to elucidate the effect of esmolol on induced hypotension for total hip arthroplasty. METHOD: Twenty patients receiving total hip arthroplasty were randomly divided to two groups. Esmolol group (10 patients) received esmolol as a hypotensive agent, and sodium nitroprusside (SNP) group (10 patients) received SNP as a hypotensive agent. We measured arterial blood gas analysis, vital sign, amounts of bleeding, amounts of transfusion and administered fluid, and various laboratory findings. RESULTS: Induced hypotension was successfully performed in either esmolol and SNP group. Heart rate increased by SNP, and decreased by esmolol. There were no statistically significant differences between the two groups in amounts of bleeding, amounts of transfusion or administered fluid, and laboratory findings. Arterial oxygen tension was relatively constant in esmolol group, but decreased in SNP group. CONCLUSION: Esmolol can be used as a single hypotensive agent during induced hypotension without significant side effects during total hip arthroplasty.

Bart's syndrome was initially described as a genodermatosis characterized by congenital localized absence of the skin with blistering and nail deformities 1-3. However, it is considered as any type of epidermolysis bullosa(EB) with localized congenital absence of the skin on the extremities. A 33-day-old fbmale baby was presented with congenital absence of the skin over the left shin and dorsa of both feet which were covered with the thin, translucent, and brown-red glistening membranes. Blistering of the right calf and left great toe nail deformity were also noted. She was diagnosed as a recessive dystrophic EB by the histopathological, ultra- structural and immunomapping studies.

We performed an analysis of corneal astigmatism of 123 eyes with suturing(sutured group) and 56 eyes without suturing(sutureless group) after phacoemulsification and PCL implantation through 7.0 mm straight incision wound 2.0-2.5 mm from superior limbus by use of algebraic and vector methods for two years following surgery. In both groups, the amount and axis of astigmatism were continued to change for 2years(p>0.05). The amount of astigmatisms in sutureless group was less than in sutured group until 2 months postoperatively(p<0.01), no significant difference from 3 months to 6 months postoperatively(p>0.05). Astigmatic changes in sutureless group were stable and had lower against-the-rule shift than the sutured group after 6 months postoperatively(p<0.01). Surgically induced astigmatism was stabilized after 1 month postoperatively in sutured group and after 2 weeks psotoperatively in suture less group(p<0.01), and it was lower in suture less group than sutured group during the two years postoperatively.(p<0.01).

Journal of the Korean Radiological Society 2001;44(3):371-376
PURPOSE: To determine the usefulness of the fat-suppressed (FS) conventional spin-echo (CSE) sequence for the diagnosis of meniscal tears. MATERIALS AND METHODS: We retrospectively reviewed 323 MR images of the knee, the standard of reference being the findings of arthroscopy. In all knees, fast SE proton density-weighted and T2-weighted sagittal and coronal images and double-echo in steady state (DESS) sagittal images were obtained, and during 202 MR Procedures, FS-CSE T1-weighted sagittal images were also obtained. The results of MR imaging were then correlated with those of arthroscopy, the accuracy with which meniscal tears were diagnosed being compared between two groups: group I (202 knees for which FS-CSE T1-weighted sagittal images were obtained), and group II (121 knees for which these images were not obtained). For statistical analysis the chi-square test was used. RESULTS: In group 1, sensitivity, specificity and accuracy were 94.7%, 92.4% and 93.5%, respectively, for the medial meniscus, and 83.3%, 95.7% and 90.5% for the lateral meniscus. In group II, the corresponding findings were 92.5%, 94% and 93.3%; and 87.3%, 98.2% and 92.5%. The differences between the groups were not statistically significant (p>0.05) CONCLUSION: For meniscal tears of the knee, the addition of FS-CSE T1-weighted MR imaging to the fast SE proton density-weighted, T2-weighted and DESS sequences does not enhance diagnostic accuracy.

PURPOSE: Kissing contusion between the posterolateral tibial plateau and lateral femoral condyle is frequently found in association with a tear of the anterior cruciate liagment (ACL). The purpose of this study was to determine which ligamentous and meniscal tears are associated with kissing contusion. MATERIALS AND METHODS: We retrospectively reviewed the findings depicted by 323 consecutive MR images of the knee and confirmed at arthroscopy. For the diagnosis of disruption, ligaments, medial menisci (MM) and lateral menisci (LM) were evaluated using accepted criteria. We compared the prevalence and location of meniscal and ligamentous tears between group I (44 knees with kissing contusion) and group II (279 knees without kissing contusion). For statistical analysis the chi-square test was used. RESULTS: ACLs were torn in all 44 knees (100%) with kissing contusion, and 78 (28%) of 279 without kissing contusion. There were ten medial collateral ligament (MCL) tears (23%) in group I, and 17 MCL tears (6%), five lateral collateral ligament (LCL) tears (2%) and ten posterior cruciate ligament (PCL) tears (4%) in group II. In group I, meniscal tears were found in 22 MM (50%) and in 19 LM (43%), while in group II, they occurred in 128 MM (46%) and 128 LM (46%). In group I, 17 (77%) of 22 MM tears and 13 (68%) of 19 LM tears were located in the posterior horn, while in group II, the corresponding figures were 97/128 (76%) and 60 of 128 (47%). The differing prevalence of ACL and MCL tears between the groups was statistically significant (p<0.05), but differences in the prevalence and location of meniscal tears were not (p>0.05). CONCLUSION: Although kissing contusion was a highly specific sign of ACL tears, its presence was also significant among MCL tears. There was no signifficant difference in meniscal tears with or without kissing contusion.

The foreign bodies in the upper GI tract are produced chiefly by accidental swallowing and rarely produce symptoms. But it is recommended to remove the foreign bodies if they produce symptoms or retained in GI tract for long duration, and if they have the possibilities of producing complications. Nowadays the development of therapeutic endoscopy enables the removal of the foreign bodies easily. We have reviewed 88 cases of foreign bodies diagnosed by endoscopy from January, 1980 to July 1990 and had the following results. 1) The most common foreign bodies were coins and bezoars, common with the ages under 10 years and over 50 years. 2) The foreign bodies were found in the upper gastrointestinal tract in the order of stomach, esophagus and duodenum. 3) The esophageal stricture especially by lye was the most common underlying cause of upper gastrointestinal foreign bodies. 4) The symptoms and complications were more common with esophageal foreign bodies. 5) By therapeutic endoscopy, the success rate for removal of foreign bodies was 98%.

A case of 42-year-oldI kidney transplant patient who developed invasive carcinama of the cervix after immunoauppresawe therepy is reported and the literature related to this diease is revuewed. The iatmgenic immunosuppresaionn renal transplantation recipients has been associated with increased incidence of malignancy in these patients. In particular, immunosuppressed women are al greater risk of developing cervical intraepithelial neoplasia and buman papillomavirus type 16 or 18 infection. So, all such individuals are required to receive periodic gynecologic examination before renal transplantation and at regular intervals thereafter so that the development of CIN may be diagnosed at an early Stage and treated effestively.
