Hemangiopericycic maningioma is clinically and pathologically similar to peripheral Hemangiopericytoma and now tends to be terned as hemangiopericytoma of central nervous system. The authors studied 3 cases of hemangiopericytic meningioma obtained from 3 patients, 1 case of meningotheliomatous meningioma, angioblastic meningioma and transitional meningioma, and 2 cases of peripheral hemangiopericytoma, which had operated from November 1988 to May 1989 at the department of neurosurgery, Pusan Inje University Hospital. The authors analysed and compared the immunohistochemical finding and light microscopic apearance. The results obtained were summarized as follows; 1) Classic maningioma (meningotheliomatous meningioma, transitional meningioma and angioblastic meningioma) shows reactivity to both EMA and vimentin. 2) Hemangiopercicytic meningioma and peripheral hemangiopericytoma are reactive only to vimentin, so the two tumors are suggested as same type of tumor. 3) One of 3 cases of hemangiopericytic meningioma shows whorling and interlacing bundles of spindle cells, the peculiar light microscopic features of transitional meningioma, suggesting transitional or mixed form of hemangiopericytic meningioma and transitional meningioma.

Angiogenesis is essential for tumor growth and metastasis, however, the prognostic value of neovascularization is undetermined. The aim of this study is to evaluate the prognostic significance of microvessel density (MVD) and vascular endothelial growth factor (VEGF) expression in breast carcinomas. An immunohistochemical stains for CD 31 (DAKO) to estimate MVD and VEGF (Santa Cruz) were done on 40 cases of invasive breast carcinoma. MVD was calculated as an average count of vessels per 200 power field in the most vascularized areas. VEGF expression was interpreted according to staining intensity and number of positive cells. Mean MVD was 35, and MVD was not correlated with lymph node metastasis or histologic grade, but high MVD (mean MVD>35) showed an increasing tendency in cases with larger size, negative ER/PR, and positive cathepsin D. All of the cases showed VEGF expression, but VEGF expression was not correlated with tumor size, histologic grade, lymph node metastasis, ER/PR status, and cathepsin D expression. These results suggest that MVD and VEGF expressions are not reliable prognostic factors.

Achilles tendon rupture is a common sports injury encountered in younger populations. Various treatment methods are used for acute and chronic rupture. Several treatments for each condition are available, each having their advantages and disadvantages. In an acute rupture, surgical treatment may be a priority for younger patients or those wishing a quick return to play, but the long-term functional outcome is similar to non-surgical treatment. In addition, the re-rupture rate shows a slight difference between the two treatments. The clinical outcomes are similar regardless of the surgical treatment, but an accelerated rehabilitation program should be accompanied by good results. In chronic and neglected rupture, surgical treatment is preferred over non-surgical treatment. Treatments are chosen based on the size of the tendon defect. This article reviews the current updates in the treatment of Achilles tendon rupture that will help clinicians choose the appropriate treatment.

Open reduction in an AO 33-A3 class distal femur transverse and comminuted fracture is often difficult due to frequent reduction loss during surgery, leading to longer operative time and increased blood loss intra-operation. In this study, the authors report a case in which the use of an offset grid plate (OsteoMed, USA) using 2.4 mm HPS (hand plating system) eased the process of fracture reduction and achieved a stable internal fixation, ultimately leading to successful osteosynthesis. The authors experienced no need for temporary fixation devices such as K-wires or screws, which are otherwise required to stabilize the reduction. The fracture reduction was stable throughout the primary fixation of the fracture using a locking plate and screws. The authors report that the advantage of the HPS plate is fitting into the cortical contour and providing stable maintenance of fracture reduction intra-operation, which would be beneficial in certain distal femoral fracture patterns.

It is well known that the Ebstein-Barr virus causes not only infectious mononucleosis in the most cases, but also occasionally causes a variety of hematologic disorders such as anemia (hemolytic anemia or aplastic anemia), thrombocytopenia, neutropenia and malignancies such as Burkitt lymphoma and nasopharyngeal carcinoma. Furthermore, recently it is has been reported that it causes leukemia even though very rarely. The authors report a case of erythroleukemia possibly related to chronic Ebstein-Barr virus infection in a 14-year-old boy with brief review of related literatures.

In comminuted patellar fractures, we performed modified tension band wiring using a FiberWire (Arthrex) instead of the conventional methods. From March 2016 to March 2018, 63 patients with patellar fractures who needed surgical treatment were treated with modified tension band wiring using two Kirschner wires (K-wires) and FiberWire. We inserted two 1.6-mm K-wires perpendicular to the fracture line after accurate reduction. With the knee flexed over 90°, we sutured around the patella using a FiberWire. Visual analog scale score and Levack's score were improved postoperatively. The mean bone union time was 5.6 months. None of the patients had breakage of wires, and nonunion with deformity occurred in one patient. We think that our method can be easier to handle and reduce irritation or breakage of the wires than conventional methods. In addition, early rehabilitation can be allowed. Therefore, we suggest that this method could be a useful method for the treatment of patellar fractures.

Recurrent spontaneous hemarthrosis is a relatively rare complication of total knee arthroplasty. This paper reports a case of a patient treated with arterial embolization for recurrent spontaneous hemarthrosis even after undergoing arthroscopic surgery. The patient had several relapses after total knee arthroplasty.

Purpose: This study was conducted to examine the effects of an educational program based on mobile SMS and counseling for colonoscopy in elderly people. Methods: The study utilized a non-equivalent control group with a non-synchronized design as a quasiexperimental research. The study subjects consisted of 72 elderly people (36 elderly people in the experimental group and 36 in the control group). Among the subjects, 49 were male (68.1%) and 23 were female (31.9%), and the age was 69.04± 6.14 years. Fortyfive subjects (62.5%) answered that they had underlying diseases, eight subjects (11.1%) had a family history of colon disease, and 61 subjects (84.7%) had undergone a colonoscopy. The experimental group was provided with an educational program based on mobile SMS and counseling when three days and one day before the test. The control group received verbal explanations using information sheet. The data were analyzed using descriptive statistics, the Chi-squares test, and the independent t-test with SPSS/WIN 21.0. Results Significant differences were found in bowel cleanliness scores (t= 3.60, p= .003) between the groups. No significant differences were seen between the groups in the sedation drug dosage (propofol (t= 1.02, p= .730), midazolam (t= 0.66, p= .380)) and time for colonoscopy (t= 1.08, p= .235). Conclusion: Based on the results of this study, an educational program based on mobile SMS and counseling for colonoscopy was proposed as an educational program before colonoscopy.

Dermatofibroma is a common benign cutaneous tumor that usually appears as a slowly growing firm nodule. Polypoid nodular dermatofibroma is one of special variants of dermatofibroma that can be rarely encountered. We reported an unusual case of polypoid dermatofibroma occurring on the right calf in a 34-year old korean male. The lesion was a red to brownish colored, rounded, hard protuberant tumor with short pedicle, measuring 2x2x1.5cm. Excised tumor showed a well- demarcated dermal lesion localized in the protruded area, and dense proliferation of fibroblasts.
