Since laparoscopic liver resection was first introduced in 2001, Korean surgeons have chosen a laparoscopic procedure as one of the treatment options for benign or malignant liver disease. We distributed and analyzed a nationwide questionnaire to members of the Korean Laparoscopic Liver Surgery Study Group (KLLSG) in order to evaluate the current status of laparoscopic liver resection in Korea. Questionnaires were sent to 24 centers of KLLSG. The questionnaire consisted of operative procedure, histological diagnosis of liver lesions, indications for resection, causes of conversion to open surgery, and postoperative outcomes. A laparoscopic liver resection was performed in 416 patients from 2001 to 2008. Of 416 patients, 59.6% had malignant tumors, and 40.4% had benign diseases. A total laparoscopic approach was performed in 88.7%. Anatomical laparoscopic liver resection was more commonly performed than non-anatomical resection (59.9% vs 40.1%). The anatomical laparoscopic liver resection procedures consisted of a left lateral sectionectomy (29.3%), left hemihepatectomy (19.2%), right hemihepatectomy (6%), right posterior sectionectomy (4.3%), central bisectionectomy (0.5%), and caudate lobectomy (0.5%). Laparoscopy-related serious complications occurred in 12 (2.8%) patients. The present study findings provide data in terms of indication, type and method of liver resection, and current status of laparoscopic liver resection in Korea.

An indirect porcine epidemic diarrhea (PED) virus (PEDV) enzyme-linked immunosorbent assay (ELISA) was compared with the serum neutralization (SN) test by testing 46 samples from experimentally infected sows, 73 samples from naive sows, and 1, 024 field sow samples from 48 commercial swine farms of undefined PED status. The SN test and the ELISA were performed using PEDV, KPEDV-9 strain. Viral proteins as a coating antigen of PEDV ELISA were extracted from the cytoplasm of PEDV-infected Vero cells using a non-ionic detergent, Triton X-100, and a simple protocol of PEDV ELISA was followed. The presence of antibodies in these experimental samples was confirmed by SN and ELISA in which the sensitivity of the ELISA was 89.1%, and the corresponding specificity was 94.5%. On testing 1, 024 field samples, an overall agreement of 84.2% was generated between the SN and ELISA. This study demonstrates that the PEDV ELISA is a useful serodiagnostic screening test at herd level for detecting swine antibodies against PEDV.

The amyloidosis combined with malignant neoplasm, especially stomach cancer, is rare. We experienced a case of a 60 year-old male patient who had complained of facial and lower leg edema. The laboratory findings were consistent with nephrotic syndrome, and CEA was slightly elevated. Gastroduodenoscopy revealed early gastric cancer, which suggested that the nephrotic syndrome should be associated with neoplasm, an example of membranous glomerulonephritis. Wedge resection of stomach was done with incidental splenectomy and liver biopsy. Following microscopic examination, amyloidosis was found to be involved in the liver and spleen. Bone marrow biopsy did not show any evidence of plasma cell dyscrasia. According to the literature, neoplasm can stimulate the production or precipitation of serum amyloid A like chronic infection and inflammation. But we cannot conclude that stomach neoplasm caused secondary amyloidosis, such as renal cell carcinoma or Hodgkin disease, regarding as the possibility of coincidental amyloidosis. We report a case of amyloidosis associated with early gastric cancer, represented by nephrotic syndrome.

Primary leptomeningeal melanomas(PLMs) are rare aggressive central nervous system(CNS) tumors without systemic foci. It can be very difficult, however, to clearly distinguish PLMs from those that have metastasized. We report a case of malignant leptomenigeal melanoma occurring in the right temporal convexity of a 77-yearold woman. Almost all malignant CNS melanomas in the old are secondary to the cutaneous melanoma and can cause diverse neurological manifestations; certain clinical findings of the presented case-namely, the patient's age, vague neurologic findings and absence of cutaneous lesions -are therefore interesting. Thorough clinical checkups, including whole-body bone scan, whole spine MRI, abdominal ultrasound, and tumor marker studies to find extracranial lesions revealed no abnormalities. Based on these clinical findings, we suppose-though are not certain-that the tumor of the presented case is a PLM.

The effect of lidocaine on the neuromuscular junction and the interaction between lidocaine and the muscle relaxant, succinylcholine(SCC) or vecuronium(VEC), were investigated in 12 cats of either sex using the sciatic nerve-anterior tibialis muscle preparation. The degree of twitch depression with lidocaine itself was 16.43+/-14.94%, and the ED from dose-response curves of SCC and VEC(8.35+/-4.62 and 6.36+/-8.03 ug/kg, respectively) in group II (under lidocaine infusion) were smaller than those(20.57+/-15.80 and 8.98+/-7.31 ug/kg) in group I (without lidocaine). There was no difference in the duration of action of SCC and VEC between the two groups, but the onset of VEC in group II was longer than in group I(p<0.05), The mean arterial pressure(MAP) after lidocaine infusion was reduced 149.17 to 130.83mmHg and MAPs at the same dose of each agent were also lower in group II than in group L The authors conclude that lidocaine itself produces the twitch depression and potentiates the SCC-or VEC-induced neuromuscular block. However, there is no influence on the duration of SCC or VEC.
