Calcification is found in 4% to 12% of renal masses due to a number of causes and can be seen in various patterns. This is found in 1% to 3% of the simple renal cysts. Among these a peripheral egg-shell type of calcification is more rare. We experienced the simple renal cyst associated with the thick egg-shell calcification on the renal upper pole in a 66-year-old female complaining upper abdominal discomfort, so we report that with literature.

A giant cell tumor of bone is a benign bone tumor, but has very high local recurrence rate and, very rarely metastasizes to the lung or a distant area. We report a case of a 29-year-old male patient presenting with a metastatic giant cell tumor of the soft tissue of the chest wall, who underwent a total resection of the radius for recurrence of the giant cell tumor. The tumor was not related to any bony structure of the thorax. We resected the tumor with a wide surgical margin. No evidence of malignancy was seen in the frozen and permanent pathological report.

We described the clinical manifestation of herpes zoster in thirteen children with underlying malignancies. Among the associated malignancies, hematologic malignancy including acute lymphotytic leukemia was the commonest and CNS tumors were also frequently associated. Pain was mild, and some showed high fever and abnormal liver function test results. Recurrent attacks were observed in 3 cases(23%). Thoracic segment and trigeminal nerve were commonly affected. In most cases, herpes zoster developed within two years after the diagnosis of the malignancy.

Background/Aims: Extracellular vesicles (EVs) are secreted from various types of cells and have specific functions related to their origin. EVs are observed in the small intestinal lamina propria (lpEVs), but their function remains unclear. This study aimed to investigate the role of lpEVs. Methods: LpEVs were isolated from antigen (ovalbumin [OVA])-fed mice (lpEVs/OVA), and administrated to the naïve mice for 5 days before induction of lung inflammation. Afterwards, the mice were sensitized and challenged with OVA to evaluate the role of lpEVs/OVA in the regulation of immune tolerance. Results: The isolated lpEVs/OVA were sphere-shaped, bi-layered vesicles of approximately 50 to 100 nm in size. The vesicles expressed CD81, A33 antigen, and major histocompatibility complex (MHC) class II on the surface. When administrated to naïve mice, the lpEVs/OVA migrated to the spleen. Intraperitoneal lpEVs/OVA administration to naïve mice decreased the immune response against sensitized antigen in a CD4+FoxP3+T cell-dependent manner. Conclusions EVs are actively secreted from small intestinal epithelial cells to deliver information about orally administered antigens to immune cells, which will facilitate the modulation of the immune response by acting as an intercellular communicasome.

PURPOSE: The purpose of the study is to compare the outcomes between three different one-layer vasovasostomy techniques: original one-layer, modified one-layer, and V-V type one-layer microsurgical vasovasostomy. MATERIALS AND METHODS: We retrospectively reviewed the charts and surgical records of all surgical procedures performed on a series of 117 consecutive patients undergoing a microsurgical one-layer, modified one-layer or V-V type one-layer vasovasostomy between May 1995 and March 2000. An original one-layer vasovasostomy was used in 48 men (group 1), a modified one-layer vasovasostomy in 35 men (group 2), and V-V type one-layer vasovasostomy in 34 men (group 3). A successful outcome (patency) was defined as sperm presenting at the follow-ups. RESULTS: The sperm concentration (million/ml) and motility (%) were as follows: in original one-layer vasovasostomy 17.5 and 32.9, in modified one-layer vasovasostomy 26.1 and 28.5 and in V-V type vasovasostomy 30.5 and 32.3. There were no significant differences in patency (85.4%, 91.4% and 91.2%) and pregnancy rate (56%, 62.5% and 63.6%) of the procedures. If the obstructive interval had been less than 4 years, patency was 87.5% and pregnancy rate was 61.5%, 5 to 9 years 95.8% and 63.4% and 10 years or more 83% and 58.3%. There were no correlations between obstructive interval and rates of patency and pregnancy. CONCLUSIONS: The patency and pregnancy rate revealed slightly better result in modified one-layer or V-V type one-layer microsurgical vasovasostomy than in original one-layer microsurgical vasovasostomy. However, they had statistically no significant differences in overall.

Leiomyoma is a benign tumor, which usually occur at the smooth muscle of the gastrointestinal tract and uterus but rarely occurs on the corpus cavernosum of the penis. We experienced a patient with leiomyomas on the bilateral corpus cavernosa of the penis accompanied with impotence in a 60-year-old man. The patient was treated with complete local excision and has remained well without recurrence for l year, So we report this case with review of literatures.

BACKGROUND: Ethanol injection during a sclerotherapy for the treatment of arteriovenous malformation, which performed under general anesthesia, can cause significant hemodynamic changes, even cardiovascular collapse. However, guideline for adequate management of hemodynamic change or preventing detrimental complication has still not been proposed. METHODS: Twenty-two piglets were randomly allocated to one of two groups: a 2.5 ml and a 4.0 ml ethanol. After baseline hemodynamic measurements, 2.5 ml or 4.0 ml of absolute ethanol was repeatedly administered in distal portion of renal vein with 10 minute intervals, and hemodynamic parameters were measured immediately before and after bolus injection of absolute ethanol until 10 minutes after final injection. RESULTS: Compared with 2.5 ml group, systolic, mean and diastolic pulmonary arterial pressures (PAP) and pulmonary vascular resistance (PVR) of 4.0 ml group showed significant differences from the first bolus injection of absolute ethanol. Hemodynamic parameters of 2.5 ml group did not show the increasing or decreasing tendency during a session, whereas, in 4.0 ml group, systolic, mean and diastolic PAP and PVR showed significantly increasing tendency. However, systemic arterial blood pressure, heart rate, central venous pressure, pulmonary capillary wedge pressure, cardiac output, and systemic vascular resistance did not show increasing or decreasing tendency in both groups. CONCLUSIONS: Based on the hemodynamic alterations observed from piglet model, the bolus injection of absolute ethanol during sclerotherapy in congenital arteriovenous malformation requires careful hemodynamic monitoring. We strongly recommend that anesthesiologist should carefully monitor the hemodynamic parameters after injection of relatively large amount of absolute ethanol.

Squamous cell carcinoma of bladder is best treated with a radical cystectomy. Squamous cell carcinoma of bladder invading the abdominal wall is not commonly reported and hard to manage surgically. Abdominal wall defect caused by a wide resection of squamous cell carcinoma invading abdominal wall can be reconstructed using various muscle flaps. We performed a salvage cystectomy for a patient with squamous cell carcinoma of bladder invading abdominal wall up to skin, and the abdominal wall defect was successfully reconstructed using a unilateral tensor fascia lata myocutaneous flap.
