  • A 62-year-old female patient suffered from numbness and resting pain in the right ring and little fingers for 3 years. We confirmed cubital tunnel syndrome with electrodiagnostic study and performed the operation. We found seven firm consistent nodules, compressing the overlying the ulnar nerve, proximal to the medial epicondyle in the operation field. Histological finding showed synovial chondromatosis. We report a rare case of a patient with cubital tunnel syndrome caused by synovial chondromatosis.

  • Background: Soft tissue sarcomas (STS) represent 1% of all malignant lesions. In this study the authors analyzed the incidence of STS in Vojvodina (the north region of Serbia) in the period from 1985 to 2009. A number of studies conducted worldwide indicate that STS incidence rates are tending to increase. Materials and Methods: On the basis of data from the Cancer Registry of Vojvodina, age standardized STS incidence rates were established as well as their linear trend, with data on histological structure, age, gender and STS distribution at specific locations. Results: The total number of registered patients was 1,308. Average age standardized rate was 1.90/100,000 per year. The investigated period showed a slight increase in the incidence rate (average annual percent increase=0.77%). The most frequent histological type was sarcoma not otherwise specified-NOS (27%), followed by leiomyosarcoma (21%), liposarcoma (14%), rhabdomyosarcoma (11%) and malignant fibrous histiocytoma (9%). The male/female ratio was 0.73:1. Every fifth patient was younger than 39. Conclusions: Comparison among eight international STS epidemiology studies show that the incidence rate range is between 1.4/100,000-5.0/100,000, though our finding is closer to the lower limit. Furthermore, the incidence rate increase was lower than that characteristic for the half of the analyzed studies. A partial explanation for that should be looked for among changes in diagnostic criteria and STS classifications.

  • The brown tumors develop in bone and it develop on various area which in clavicle, rib bone, cervical bone, iliac bone etc. The development on the maxillofacial region is rare, relatively more develop on the mandible. The brown tumor directly develop by the dysfunction of calcium metabolism according to hyperparathyroidism and differential diagnosis with other bone lesion should be difficult if it would diagnose by only radiographic features. The histological feature is that proliferation of spindle cells with extravasated blood and haphazardly arranged, variably sized, multinucleated giant cell is seen. The brown tumor is firm diagnosed by physical examination, because of these histological feature show similar with other giant cell lesions(giant cell granuloma, aneurysmal bone cyst, cherubism). The brown tumors have been described as resulting from an imbalance of osteoclastic and osteoblastic activity. It result in bone resorption and fibrous replacement of the bone. So these lesions represent the terminal stage of hyperparathyroidism-dependent bone pathology. Therefore, it is the extremely rare finding that brown tumor in the facial bone as the first manifestation of an hyperparathyroidism. We experience 1 case of brown tumor(50 years old female) that developed on Maxilla and mandible with no history of hyperparathyroidism. So we report this case with a literature review.

  • Purpose: Dermoid cysts are almost always caused by congenital events. The most widely accepted pathogenesis is that the cysts are dysembryogenetic lesions that arise from ectodermic elements entrapped during the midline fusion. We report a rare case of dermoid cyst, which occurred not congenitally but newly in the subcutaneous scar tissue secondary to trauma. Methods: A 26-year-old man had a deep submental laceration caused by a car accident and got a primary wound closure 16 months ago. There were 18 cm-long submental hypertrophic scar and newly developed palpable masses inside the subcutaneous layer at the center of the scar. Initial impression was an epidermal cyst or a thyroglossal duct cyst. Ultrasonographic finding showed two cystic masses inside the scars at the submental area, but impressed dermoid cysts. The cystic masses were completely removed with W-plasty and histological examination were followed. Results: The histological diagnosis was dermoid cysts which were mainly composed of keratotic squamous epithelium in their inner surface linings and numerous skin appendages such as sebaceous glands, sweat glands, and hair follicles in their cystic lumens histopathologically. During the follow-up period of 25 months, there was no recurrence of any subcutaneous mass in the site of scar. Conclusion: We report a very unusual case of dermoid cysts developed by an acquired cause, considering that the accidental inclusion of deep skin elements caused by a trauma can be a critical origin of dermoid cysts.

  • This study was attempted to evaluate home-manufactured implants by placing $Stage-1^{(R)}$ Implant (Lifecore, Co., USA) whose surface is treated with REM that has already been varified clinically,$Chaorum^{(R)}$ Implant(Chaorum Co., Korea) whose surface treatment is same as that of Stage-1 Implant and $Atlas^{(R)}$ Implant(Cewellmedi Co., Korea) whose surface is treated with anodic oxidation immediately after the teeth of experimental animals were extracted to compare histological findings among them. Stage-l Implant(diameter: 3.5mm, length: IOmm), Chaorum Implant(diameter: 3.3mm, length: 8.5mm) and Cowell medi Implant(diameter: 4.0mm, length: 8.0mm) were placed into the mandible premolars of 2 adult beagle dogs immediately after their teeth were extracted, and then histological findings were analyzed at 6 weeks. After those implants were inserted directly after their teeth were extracted, the results of periotest were recorded, radiography was done, the subjects went through thorough control for 6 weeks, and then comparison among periotest, radiography and histological finding was made. After comparison of those findings, the values of periotest were satisfactory and bone healing was relatively satisfactory on radiography at 6 weeks. For osseointegration with the bone tissue, Stage-1 was 45.3%, Chaorum 55.3%, and Cowellmedi 52.5%, which was a satisfactory result. Although implant surgery immediately after teeth were extracted involves difficulties among recent implant surgeries, it is being frequently used in that it may reduce surgery hours, the frequency of surgery, and bone loss for patients. This experiment was conducted to evaluate the technological levels of home-manufactured implants that have been remarkably developed in recent years and in conclusion, those implants showed nearly similar result.

  • To investigate effects of vanous herbal-acupuncture, which were Daebangpungtang, Oyaksungisan, Dokhwalgisaengtang, and Binsosan on Adjuvant Arthritis in rats, the edema rate, the number of WBC, the quantity of TNF-${\alpa}$, COX -2, and IL-6, and histological test of the muscular tissue were measured in the arthritis part. After elicilating arthritis of Sprague Dawely(SD) rats by injection of Freund's complets adjuvant for 2 weeks, saline was injected for the control group, Daebangpungtang acua-acupuncture was injected for the Daebangpungtang group, Oyaksungisan acua-acupuncture was injected for the Oyaksungisan group, Dokhwalgisaengtang acua-acupuncture was injected for the Dokhwalgisaengtang group, and Binsosan acua-acupuncture was injected for the Binsosan group during 30days. Selected point was ST35 in all groups. 1. The number of WBC was $8.24{\pm}0.51$($10^3$/ml) in the normal group and $27.35{\pm}3.51$($10^3$/ml) in the control group. the Daebangpungtang group and the Oyaksungisan group decreased each $20.42{\pm}2.75$($10^3$/ml) and $19.78{\pm}4.99$($10^3$/ml) in the Exp.ll group. This fact showed that the group Exp.ll was more effective than the control group effectively. (P<0.05) 2. The volume of the paw were checked. The volume of paw was $0.62{\pm}0.11mm in the control group and $0.45{\pm}0.08$mm in the Daebangpungtang group and $0.47{\pm}0.07$mm in the Oyaksungisan group, the swelling of the paw was restricted significantly in the Daebangpungtang and Oyaksungisan group(P<0.05) 3. The bands of the TNF-${\alpa}$, COX -2 in the muscular tissue of the control group wcre certain and thick than other groups(except normal group), and the band of the IL-6 in the muscular tissue of all group(except normal group) were similar forms. 4. In histological finding, because of severe inflammatory reaction, remarkably irregular tissue and large amount of inflammatory cells were found in thc control and Dokhwalgisaengtang group. But the Oyaksungisan and Daebangpul1gtang group showed small amount of inflammatory cells, the refrained inflammatory state and even recovering state. From these results, it is showed Oyaksugisan and Daebangpungtang acua-acupuncturc refrain inflammatory reaction and muscular tissue necrosis in SD rats paw were induced by Freund's complete adjuvant

  • Objective: The primary objective of this study was to perform a retrospective evaluation of the radiological and pathological features influencing the formation of peritumoral brain edema (PTBE) in meningiomas. Methods: The magnetic resonance imaging (MRI) and pathology data for 86 patients with meningiomas, who underwent surgery at our institution between September 2003 and March 2009, were examined. We evaluated predictive factors related to peritumoral edema including gender, tumor volume, shape of tumor margin, presence of arachnoid plane, the signal intensity (SI) of the tumor in T2-weighted image (T2WI), the WHO histological classification (GI, GII/GIII) and the Ki-67 antigen labeling index (LI). The edema-tumor volume ratio was calculated as the edema index (EI) and was used to evaluate peritumoral edema. Results: Gender (p=0.809) and pathological finding (p=0.084) were not statistically significantly associated with peritumoral edema by univariate analysis. Tumor volume was not correlated with the volume of peritumoral edema. By univariate analysis, three radiological features, and one pathological finding, were associated with PTBE of statistical significance: shape of tumor margin (p=0.001), presence of arachnoid plane (p=0.001), high SI of tumor in T2WI (p=0.001), and Ki-67 antigen LI (p=0.049). These results suggest that irregular tumor margins, hyperintensity in T2WI, absence of arachnoid plane on the MRI, and high Ki-67 LI can be important predictive factors that influence the formation of peritumoral edema in meningiomas. By multivariate analysis, only SI of the tumor in T2WI was statistically significantly associated with peritumoral edema. Conclusion: Results of this study indicate that irregular tumor margin, hyperintensity in T2WI, absence of arachnoid plane on the MRI, and high Ki-67 LI may be important predictive factors influencing the formation of peritumoral edema in meningiomas.

  • Objectives : To evaluate the toxicity of KOB03, polyherbal medicine for the treatment of allergic rhinitis, we performed the dose-range finding test of KOB03 by oral supplementation for 4 weeks in Sprague-Dawley rats. Methods : The water extract of KOB03 consisting of five different herbs was supplied from GLP company. KOB03 was supplemented by gavage at 0, 500, 2,500 and 5,000 mg/kg/day for 4-week consecutive days. We recorded the clinical signs of toxicity, body weight, organ weights, hematology, gross and histological changes in target organs of rats, and clinical chemistry analysis. Results : KOB03 at all doses was shown no mortality or abnormal clinical signs in rats during at the observation period. Furthermore, there was no difference in body weight and food-take consumption, organ weight, gross pathological findings, and urine analysis among the groups of rats treated with different doses of KOB03. The hematological analysis and clinical blood chemistry data were revealed no toxic effects from KOB03-supplemented rats. Conclusions : The results suggest that KOB03 is a wide margin of safety on dose-range toxicity in rats. The no observable adverse effect level (NOAEL) of the test, KOB03 in rats is no less than 5,000 mg/kg/day.
