Abstract PDF: Extramedullary plasmacytoma (EMP) is a rare disease that occurs in 3% to 5% of patients with plasma cell disorder. It occurs most commonly in the upper respiratory tract and the oral cavity. Very few EMP cases have been reported in the central nervous system (CNS). We report herein an unusual case of EMP in the nasal cavity that recurred in the CNS without systemic involvement. A 67-year-old man visited our hospital due to a month-long bout with exophthalmos. He was diagnosed with EMP in the nasal cavity, paranasal sinus, and orbital cavity. He received radiotherapy to which he had complete responses. After 2 years, he visited our hospital because of a month-long headache. He was diagnosed with EMP recurrence in the CNS via brain magnetic resonance imaging and cerebrospinal fluid analysis. He was treated with whole brain radiotherapy and intrathecal chemotherapy with methotrexate, but he expired due to pneumonia.

Cardiovascular Effects of Free Movement of Abdominal Muscle in Prone Positioning during General Anesthesia.: Ji Yoon Kim, Dong Won Lee, Il Sook Seo, Sae Yeon Kim; Yeungnam Univ J Med. 2007;24(2):206-215. Published online December 31, 2007; DOI: https://doi.org/10.12701/yujm.2007.24.2.206

BACKGROUND
The prone position is often used for operations involving the spine and provides excellent surgical access. The complications associated with the prone position include ocular and auricular injuries, and musculoskeletal injuries. In particular, the prone position during general anesthesia causes hemodynamic changes. To evaluate the cardiovascular effects of the prone position in surgical patients during general anesthesia, we investigated the effects on hemodynamic change of the prone position with the Jackson spinal surgery table. MATERIALS AND METHODS:Thirty patients undergoing spine surgery in the prone position were randomly selected. After induction of general anesthesia, intra-arterial and central venous pressures (CVP) were monitored and cardiac output was measured by NICO(R). We measured stroke volume, cardiac index, cardiac output, mean arterial pressure, heart rate, CVP and systemic vascular resistance (SVR) before changing the position. The same measurements were performed after changing to the prone position with the patient on the Jackson spinal surgery table. RESULTS: In the prone position, there was a significant reduction in stroke volume, cardiac index and cardiac output. The heart rate, mean arterial pressure and CVP were also decreased in the prone position but not significantly. However, the SVR was increased significantly. CONCLUSION: The degree of a reduced cardiac index was less on the Jackson spinal surgery table than other conditions of the prone position. The reduced epidural pressure caused by free abdominal movement may decrease intraoperative blood loss. Therefore, the Jackson spinal surgery table provides a convenient and stable method for maintaining patients in the prone position during spinal surgery.

Abstract PDF: BACKGROUND
Matrix metalloproteinases (MMPs) are involved in the degradation of the extracellular matrix, which is an important step in tumor invasion and metastasis. A positive correlation between the expression of MMP-9 and aggressive behavior of renal cell carcinomas (RCCs) has been reported. MMP-9 expression in RCCs and adjacent normal kidney tissues were examined in this study. MATERILAS AND METHODS: Twenty-five patients pathologically diagnosed as clear cell RCCs, from specimens obtained at radical nephrectomy, between May 2003 and December 2004 were enrolled in this study. MMP-9 activity was estimated using gelatin zymography, and quantified using a laser densitometer. The results were compared with clinicopathological characteristics. RESULTS: The expression of MMP-9 was significantly elevated in the RCC compared with non-tumor kidney specimens (p<0.01). The levels of MMP-9 expression in the RCC patients with large tumors (>4 cm) or vascular invasion were significantly higher than in those without these clinical manifestations (p<0.01). There were also significant differences in the expression of MMP-9 among T stages (p<0.01). The tissue MMP-9 level was the highest in nuclear grade 4, but there was no statistical significance between the histological grades (p=0.17). CONCLUSIONS: These results suggest that enhanced MMP-9 expression contributes to carcinogenesis and tumor progression in the later stages of RCC.

Intratesticular Simple cyst lined by ciliated columnar epithelium: A Case Report.: Ji Yoon Kim, Hwa Soo Lim, Ki Hak Moon, Mi Jin Kim, Jae Ho Cho; Yeungnam Univ J Med. 2005;22(2):266-269. Published online December 31, 2005; DOI: https://doi.org/10.12701/yujm.2005.22.2.266

Abstract PDF: An intratesticular simple cyst is a rare lesion. The pathogenesis of such lesions is uncertain. Clinically, an intratesticular simple cyst may be difficult to differentiate from a cystic neoplasm. However, preoperative diagnosis is possible using ultrasonography (US). Testis-sparing surgery with simple enucleation of the cyst has a favorable outcome. We report an intratesticular simple cyst in a 48-year-old male who had a non-tender cystic mass in the right testis for 2 years. The diagnosis was made by preoperative US. The patient underwent a testis-sparing surgery. After simple excision of the cyst, histological examination revealed a simple cyst lined by ciliated cuboidal and columnar epithelium.

Malignant Fibrous Histiocytoma of the Spermatic Cord: A Case Report.: Ji Yoon Kim, Seong Ho Lee, Hee Chang Jung, Dong Sug Kim, Jae Ho Cho; Yeungnam Univ J Med. 2003;20(1):85-91. Published online June 30, 2003; DOI: https://doi.org/10.12701/yujm.2003.20.1.85

Abstract PDF: Malignant fibrous histiocytoma (MFH) of the spermatic cord represents an uncommon location for the most common soft tissue tumor in adults. MFH of the spermatic cord is extremely rare. No case report has been described in the Korean literature. We report a case of malignant fibrous histiocytoma, myxoid type, arising from left spermatic cord. A 77-year-old male presented with a painless left upper scrotal mass for 5 months. Simple mass excision was performed for a diagnosis. Grossly, the mass closely contacted with the left spermatic cord. Since a myxoid type of malignant fibrous histiocytoma was diagnosed from histopathological findings, left radical orchiectomy with high ligation of the spermatic cord was performed additionally. There were no evidence of local recurrence or metastasis at 6 months after surgery.
