BACKGROUND: We analyze the functional evaluation, posterior stability after surgery of acute injuries in the femoral detachment and tibial avulsion fracture of posterior cruciate ligament. MATERIALS AND METHODS: Twenty two patient who underwent primary repair were followed more than one year after operation (mean follow-up 33.7 months). The patients were evaluated with KT 2000 arthrometer and posterior stress test for posterior stability. Lysholm knee score was used for knee function. RESULTS: Lysholm score revealed 85.3 in femoral detachment group and 91.1 in tibial avulsion fracture group (p<0.05). Posterior displacement of the posterior stress test showed 17.2 mm at initial injury and 8.6 mm at last follow up in femoral detachment group. 16.8 mm at initial injury and 7.1 mm at last follow up in tibial avulsion fracture group There revealed the tendency of the improved posterior stability of the tibial avulsion group compared with femoral detachment group, but there showed no statistical significance in KT 2000 arthrometer and posterior stress x-ray. CONCLUSION: Functional results of tibial avulsion fracture group revealed the better outcome compared with femoral detachment group, but the degree of posterior stability in tibial avulsion fracture group showed no statistical significance in posterior stability.

3.Presumed Ischemic Unilateral Oculomotor Nerve Palsy Developing after a Snake Bite
Journal of the Korean Ophthalmological Society 2020;61(7):839-842
Purpose:
We report a patient with presumed ischemic unilateral oculomotor nerve palsy developing after a snake bite on the right finger.Case summary: A 58-year-old male visited our emergency department complaining of right ptosis and binocular diplopia that had developed after a snake bite. He had been bitten on a finger of the right hand by an unidentified snake about 6 hours prior to symptom onset. He lacked neurological symptoms such as headache, nausea, vomiting, or an altered consciousness level. The right hand exhibited severe swelling, oozing, and inflammation. The visual acuity was 20/25 in both eyes. Ptosis was evident in the right eye. Both pupils responded normally to light and near stimulation. Extraocular examination revealed movement limitations in all right-eye gaze fields except abduction. A serological test revealed coagulopathy. Pyridostigmine was prescribed, but the ocular symptoms did not immediately improve; however, they did improve gradually during follow-up. At 8 months after the initial visit, the patient exhibited an ortho primary gaze with an adduction limitation of -1. No aberrant regeneration was apparent.
Conclusions
Unilateral oculomotor nerve palsy can develop after a snake bite, possibly attributable to microvascular ischemia caused by coagulopathy.

Pancreas lipomatosis is definde as fatty replacement of pancreatic acinar cells. Of the nine cases evaluated, seven cases (77.8%) of lipomatosis were limited inbody and tail, one case (11.1%) showed total lipomatosis excluding uncinate process and the remaining one case (11.1%) only in tail. As to the severity of lipomatosis, complete fat replacement in body and tail was found in four cases (44.4%), incomplete body and complete tail involvement in two (22.2%), incomplete body and tail, complete all except uncinate process, and complete tail involvements were found in one case (11.1%) each. Associated or predisposing factors included three diabetes mellitus (33.3%) combined with pancreas divisum, pancreas lithiasis and cholelithiasis respectively, hepatitis (22.2%) in two, and pseudocyst (11.1%) in one case, but in three cases (33.3%) nothing was found. In conclusion, pancreas lipomatosis was easily diagnosed by the abdominal CT and it was associated or predisposed by several e tities but had no major clinical symptoms, such as pancreatic insufficiency.

Actinomycosis is an oppoturnistic infection of actinomyces, which are relatively avirulent endogenous oral commensals. After trauma or infection, they breach the normally protective mucosal barriers to invade adjacent soft tissue structures. Lesions routinely contain other bacteria, the normal resident flora at the site of primary infection, which act synergistically with actinomyces species to provoke this unique infection, which range from an acute suppurative process to a chronic fibrotic process. According to epidemic studies about pelvic actinomycosis, it should be significantly related to IUD(intrauterine device). It is accounted that IUD cause chronic intrauterine infection, tissue injury and act as nucleus for parasitic infestation. Here we present a case of pelvic actinomycosis related to IUD with brief review of the concerned literature.

Journal of the Korean Society of Magnetic Resonance in Medicine 2000;4(2):107-112
PURPOSE: To evaluate the usefulness of comparison of the signal intensity of uterine septum in the differential diagnosis of bicornuate and septate uterus on magnetic resonance (MR) imaging. MATERIALS AND METHODS: Preoperative MR imaging findings of surgically proven 5 bicornuate and 6 septate uteri were retrospectively analyzed. Because preoperative differential diagnosis of both was possible in all cases in terms of the intercornual distance, external contour of uterine fundus, and divergent angle of two uterine cavities, these criteria were excluded in this study. The signal intensity of uterine septum in patients with bicornuate and septate uterus was analyzed on T1-weighted and fast spin echo T2-weighted images obtained in the axial and coronal planes, using a 1.5-T MR scanner. The signal intensity of uterine septum especially on T2-weighted images was compared with that of myometrium or junctional zone. RESULTS: The signal intensity of uterine septum in patients with bicornuate uterus (n=5) and septate uterus (n=6) was similar to that of myometrium in all cases on T1-weighted images. The septum of bicornuate uterus (n=5) on fast spin echo T2-weighted images was isointense with myometrium in three and hypointense in two cases. The uterine septum of septate uterus (n=6) on T2-weighted images was isointense with myometrium in two, hypointense in two, and isointense with or more hypointense than junctional zone in two cases. No patient showed different signal intensity between upper and lower uterine septum. CONCLUSION: Because the MR signal intensity of the uterine septum in bicornuate or septate uterus is variable, it should not be used alone in the differential diagnosis of them. In these clinically important differentiation, therefore, comprehensive analysis of MR findings in terms of the external contour of uterine fundus, intercornual distance, divergent angle of two uterine cavities, in addition to the signal intensity of the uterine septum, should be considered.

PURPOSE: To assess the accuracy of MR cholangiography(MRC) in the diagnosis of cholelithiasis, and to determine interobserver agreement. MATERIALS AND METHODS: Between March and September 1999, 43 consecutive patients with biliary obstruction [24 men and 19 women aged 25 -85 (mean, 58) years] underwent MRC using the single-shot fast spin-echo technique. Heavily T2-weighted source images(axial and coronal) 3 -5 mm thick and 12 projection images with 15- degree rotation and 5-cm thickness were obtained. All images were reviewed blindly and indepen-dently by two radiologists specialized in the interpretation of abdominal imaging information. Choledocholithiasis was evaluated in eight segments of the intrahepatic duct(IHD), extrahepatic duct(EHD) and gall bladder lumen. Final diagnosis was established on the basis of operative (n=31) and other radiological (n=12) findings. The sensitivity, specificity and accuracy of the MRC findings were assessed, and using kappa measurement (cross-table analysis,SPSS Windows for 8.0), interobserver agreement was determined. RESULTS: Thirty of the 43 patients, had choledocholithiasis (IHD stones in 7 cases, EHD stones in 15, and GB stones in 18). For radiologist 1, sensitivity, specificity and accuracy were 86%, 100% and 98%, respectively, in the diagnosis of IHD stones; 100%, 89% and 93%, respectively, in the diagnosis of EHD stones; and 81%, 96% and 91%, respectively, in the diagnosis of GB stones. For radiologist 2, the corresponding figures were 86%, 94% and 93% (1HD stones); 87%, 89% and 88% (EHD stones); and 81%, 86% and 84% (GB stones). Interobserver agreement for the diagnosis of choledocholithiasis was excellent in all cases. The kappa mesurement was 0.91 for 1HD stones, 0.77 for EHD stones, and 0.70 for GB stones. CONCLUSION: MRC is an excellent imaging modality for the diagnosis of choledocholithiasis, and interobserver agreement was also excellent.

Journal of the Korean Ophthalmological Society 2021;62(11):1465-1477
Purpose:
We comparatively analyzed the microbiological profiles, predisposing factors, clinical aspects, and treatment outcomes of patients with polymicrobial and monomicrobial bacterial keratitis.
Methods:
A total of 194 cases of culture-proven bacterial keratitis treated between January 2007 and December 2016 were reviewed. Microbiological profiles, the epidemiology, predisposing factors, clinical characteristics, and treatment outcomes were compared between the polymicrobial group (polymicrobial bacterial keratitis [PBK]; 29 eyes, 62 isolates) and monomicrobial (monomicrobial bacterial keratitis [MBK]; 165 eyes, 165 isolates) group.
Results:
The most common isolates were Enterobacter (24%) in the PBK group and Staphylococcus (22%) in the MBK group. There were no significant differences between the two groups in previous ocular surface disease, previous ocular surgery, prior topical steroid use, epithelial defect size, and hypopyon. Age ≥60 years (PBK vs. MBK, 31% vs. 51%, p = 0.048), symptom duration (4.7 days vs. 8.0 days, p = 0.009), and contact lens use (34% vs. 18%, p = 0.036) were significantly different between the two groups. Regarding treatment outcomes, epithelial healing time ≥10 days, the final best-corrected visual acuity (BCVA), a need for surgical intervention, and the rate of poor clinical outcome were not significantly different between the two groups. Significant risk factors for a poor clinical outcome in all patients were an initial BCVA <0.1 (Z = 6.33, two-proportion Z-test), an epithelial defect size ≥5 mm2 (Z = 4.56), and previous ocular surface disease (Z = 4.36).
Conclusions
Polymicrobial bacterial keratitis, compared to monomicrobial bacterial keratitis, was more significantly associated with younger age, contact lens use, and shorter symptom duration.

PURPOSE: To analyze minimum 2-year clinical and radiological follow-up results of primary total knee replacement arthroplasty (TKRA) with metal block augmentation for tibial bony defect. MATERIALS AND METHODS: We analyzed 67 cases (52 patients) of primary TKRA with metal block augmentation for tibial bony defects from March 1999 and March 2008. Clinical results were evaluated using the Knee Society clinical rating system and the Western Ontario and McMaster University (WOMAC) score. Radiologic results were evaluated using the Knee Society roentgenographic evaluation system. RESULTS: The mean knee score and function score improved from 42.0 and 45.6 preoperatively to 94.5 and 85.4 postoperatively. At last follow-up, the mean WOMAC score was 16.8. The incidence of radiolucent lines was 10% (7 cases) during the follow-up period, but there was no case of progression. There were no statistically significant differences between the groups divided according to the block size (below 5 mm and over 8 mm) and between the stem and no-stem groups for all parameters. CONCLUSIONS: Primary TKRA with a metal block produced satisfactory results for the minimum 2-year follow-up and can be considered as a simple and effective method for the treatment of tibial bony defect in primary TKRA.
