The ankle is a complex structure supporting the entire musculoskeletal system during standing and walking. The injuries to the ankle joint result in a severe functional disturbance because of complex anatomical characteristics around the ankle joint. 69 patients(72 cases) of the ankle fracture that were treated in Orthopedic Dept. Chonbuk National University Hospital from Jan. 1979 to Dec. 1983 were analized in clinical and radiological aspects. The following results were obtained: 1. Among the 69 patients, male was 54 and female 15 with ratio of 3.5: 1.The average age was 32. 2. Main cause of fracture was traffic accident(58%). 3. The musculoskeletal system was injured most frequently associated with the ankle fracture(66%). 4. According to the ankle fracture classification, the most common type was Pronation-external rotation type in Lauge-Hansen classification, and the type C in Weber classification. 5.The average duration of cast immobilization was 8.8 weeks in closed reduction and 7.4 weeks in open reduction. 6. The lateral malleolar fracture involving the distal tibiofibular syndesmosis was very important in ankle stability so accurate anatomical reduction by internal fixation was necessary for satisfactory functional results. 7. In clinical and radiological analysis, the better results were obtained from open reduction.

Renal dysplasia results from aberrant metanephric histogenesis caused fundamentally by a defect in inducer tissue or responding tissue. Dysplastic kidneys vary tremendously in gross and microscopic appearance but are characterized by abnormal organization and a mixed population of primitive structures, such as fetal or immature cartilage, dysplastic ducts, immature tubules, and undifferentiated mesenchyme. We report a case of unilateral multicystic renal dysplasia associated with an ipsilateral ectopic ureteral orifice entering a seminal vesicle cyst in a 33-year-old man. He was admitted due to primary infertility which had developed three years ago. The his semen analysis revealed oligospermia. No evidence of a family history of renal dysplasia was reported. Microscopic examination showed that the entire kidney was composed of cysts lined by flattened cells, dysplastic ducts and immature tubules surrounded by collars of spindle cells, primitive mesenchyme, and a few aberrantly formed glomeruli.

A muscular calf is esthetically unappealing in Asian women. Treatment by liposuction alone has poroven to be difficult due to a small amount of fat. We established a new method of transecting half of the gastrocnemius tendon in order to improve the contour of the calf. Thirty-five patients were operated on during the past 3 years. The medial or lateral half of the gastrocnemius tendon was cut using an endoscopic-guided 3M AGEE blade through a 1cm-sized incision. The portion of the muscle above the site of the transection was elevated from the underlying soleus muscles. We checked the calf circumference and evaluated the clinical results at 6 months postoperatively. An average 10% reduction in calf circumfernce was measured, showing a significant esthetic improvement. There were no significant changes in gait analysis or in the Cybex test. There were no specific complications related to the procedure. Through our clinical experience in 35 cases, we were able to prove that tenotomy is a effective, simple and easy method without severe morbidity.

Multilocular cystic renal cell carcinoma is a distinct subtype of renal cell carcinoma with its pathological characteristics and good prognosis. Multilocular renal cysts and renal cell carcinoma with cystic change are important differential diagnoses. We report a case of multilocular cystic renal cell carcinoma in a 37-year-old woman who came to the hospital because of the right renal mass. The removed right kidney showed a 6x4 cm well defined cystic mass in the lower pole. On cut section there were multiple cavities in the mass, filled with serosanguineous fluid and focal yellowish solid area. Microscopically, these cysts were lined by a single layer of flat or cuboidal cells consisted of clear cytoplasm with small central nuclei. In some portions of the tumor, the clear neoplastic cells formed sheets within the septa or walls of the cysts.

Korean Journal of Pathology 1999;33(6):443-449
Inactivation of tumor suppressor genes may play an important role in many human cancers including breast. This study was done to determine the relationship between the expression of p53 and Rb protein and prognostic factors such as histopathologic differentiation, tumor size, and lymph node metastasis. In 57 cases of breast invasive ductal carcinomas, the immunohistochemical staining with p53 and Rb protein gave the following results: p53 protein was detected in 45.6% (26/57) of cases. Tumors with large size, poor differentiation or lymph node metastases tended to show increased expression of p53 protein. However, p53 protein expression did not show any significant correlation with prognostic factors such as tumor size (p value 0.25), histologic grade (p value 0.75), and positive lymph node status (p value 0.26). Rb protein was detected in 57.9% (33/57) of cases. Rb protein also did not show any significant correlation with prognostic factors such as tumor size (p value 0.56), histologic grade (p value 0.71), and positive lymph node status (p value 0.98). There was no significant correlation between p53 expression and Rb protein expression (p value 0.80).

The acinic cell carcinoma (ACC) is very rare in the nasal cavity. A 57-year-old woman suffered from nasal obstruction, postnasal dripping, and hyposmia for 2 months. Rhinoscopic examination revealed a huge polypoid mass in the right inferior and anterior nasal fossa of the nasal cavity and the mass was resected. The tumor showed the classic acinar and trabecular features of ACC on light microscopic examination. The finely granular cytoplasmic granules stained with periodic acid-schiff (PAS) and diastase digested-PAS, but not with alcian blue at pH 2.5 and mucicarmine. On ultrastructural examination, tumor cells contained numerous secretory granules diagnostic of ACC.

OBJECTIVE: The cyclin-dependent kinase inhibitor p27kip1 protein is a negative regulator of the cell cycle, and its degradation is required for entry into the S phase. Loss of p27kip1 expression has been reported to be associated with aggressive behavior in a variety of tumors of epithelial and lymphoid origin. However, its association with various astrocytic tumors has not been clearly demonstrated. We studied to investigate the relationship of p27kip1 expression with the biological behavior of astrocytic tumors in addition to study on the role of p27kip1 in the tumorigenesis of these tumors. PATIENTS AND METHODS:From 1990 to 1998, a total of 29 astrocytic tumor of all grades obtained by operative resection were included for evaluation. We studied the expression of p27kip1 protein immunohistochemical assay in astrocytic tumors and compared the findings with the clinicopathologic parameters. Immunohistochemical staining was performed on formalin-fixed paraffin-embedded sections by the avidin-biotin-peroxidase complex method. According to WHO classification, all cases were divided into astrocytomas(4 cases), anaplastic astrocytomas(9 cases), and glioblastomas(16 cases) by 3 pathologists. Clinical information was obtained from medical records, and others such as location and size of tumors from imaging studies. RESULTS: Mean p27kip1 protein labeling indexes(LI, mean+/-standard deviation) of astrocytomas, anaplastic astrocytomas, and glioblastomas were 80.6+/-9.1, 63.6+/-21.0, and 28.9+/-18.7, respectively, and were inversely correlated with grade of glial tumors(p<0.0001). Mean p27kip1 protein LI in the recurrent group was lower than that in the non-recurrent group, but there was no significant difference statistically(p=0.464). Additionally, p27kip1 protein expression did not show any significant relationship to other prognostic factors such as age(p=0.1643), tumor size(p=0.8), or location(p=0.8). CONCLUSION: These results suggested that reduced expression of p27kip1 protein may play a important role in the malignant transformation process of astrocytic tumor cells.
