The well-known prognostic factors for breast cancer, such as axillary lymph node status, do not always account for the exact outcome. The development of other accurate prognostic factors would help in assessing high risk for the disease recurrence and death. Recently, there are reports that peritumoral lymphatic vessel invasion is a good prognostic factors to solid tumors in animal studies and clinical trials. This study was performed to estimate the significance of peritumoral lymphatic vessel invasion (PLVI) as a prognostic factor in breast cancer. Also, PLVI was compared withb establishwd established clinicopathological prognostic factors and hormone receptors. MATERIALS AND METHODS: A group of patient was selected from the Department of Surgery, College of Medicine, Hallym University, which consists of 43 out of 96 patients who received curative operation from 1985 to 1993. Peritumoral lymphatic vessel invasion by tumor cells on H&E stain was considered PLVI positive. We classified 43 breast-cancer patients into 32 with negative PLVI and 11 with positive PLVI. We estimated the correlation between the PLVI and other established prognostic factors. We also calculated survivals based on PLVI. RESULT: The 4-year disease-free survival rate was 61.8+/-.7%, and the 4-year overall survival rate was 73.0+/-.0%. The receptor status of estrogen and of progesterone had significant impacts on survival (ER: p=0.0001, PR: p=0.0001). Also, metastasis status of lymph node had significant impacts on overall survival (p=0.0148). We found a significant correlation between PLVI and tumor size (p=0.004), estrogen receptor (p=0.002), progesterone receptor(p=0.006), but could not find any significant correlation between PLVI and menopausal status, histologic grade, unclear grade, lymph node metastasis. PLVI status was correlated with disease free survival rate (p=0.01) and overall survival rate(p=0.01). CONCLUSIONS: The determination of PLVI in breast cancer tissue may be useful as a prognostic factor, but it is necessary to investigate the PLVI in a large number of patients before this conclusion can be stated with certainty.

We estimated the correlation between the PLVI and other established prognostic factors. We also calculated survivals based on PLVI. RESULTS: The 4-year disease-free survival rate was 61.8+/-8.7%, and the 4-year overall survival rate was 73.0+/-8.0%. The receptor status of estrogen and of progesterone had significant impacts on survival (ER: p=0.0001, PR: p=0.0001). Also, metastasis status of lymph node had significant impacts on overall survival (p=0.0148). We found a significant correlation between PLVI and tumor size (p=0.004), estrogen receptor (p=0.002), progesterone receptor (p=0.006), but could not find any significant corelation between PLVI and menopausal status, histologic grade, nuclear grade, lymph node metastasis. PLVI status was corelated with disease free survival rate (p=0.01) and overall survival rate (p=0.01). CONCLUSION: The determination of PLVI in breast cancer tissue may be useful as a prognostic factor, but it is necessary to investigate the PLVI in a large number of patients before this conclusion can be stated with certainty.

A 7 year-old girl presented with generalized muscle weakness and delayed motor development. She was able to stand up at 15 months and began to walk at 4 years of age. A nerve conduction study showed severe demyelinating neuropa-thy .There was no family history of peripheral neuropathy, and her parents and younger brother were clinically and electrophysiologically normal. A sural nerve biopsy showed moderate loss of myelinated fibers with onion-bulb forma-tions. Many teased nerve fibers revealed typical tomaculous changes. However the molecular genetic study of the patient confirms the duplication of 17p11.2-p22 on a polymerase chain reaction using D17S261 as a primer but not in her parents.

OBJECTIVE: The effect of induced hypothermia on severe acute carbon monoxide (CO) poisoning remains to be addressed further. We investigated the effect of induced hypothermia on severe acute CO poisoning. METHODS: Retrospective chart review was conducted for patients who diagnosed as severe acute CO poisoning in emergency department and underwent induced hypothermia from May 2013 to May 2014. Hospital courses with critical medication and major laboratory results were investigated through the chart review. RESULTS: Among total 227 patients with acute CO poisoning during the period of study, patients with severe acute CO poisoning were 15. All patients underwent induced hypothermia with a temperature goal 33°C. Initial and follow-up levels of S100B protein after induced hypothermia were 0.47 μg/L (interquartile range, 0.11 to 0.71) and 0.10 μg/L (interquartile range, 0.06 to 0.37), respectively (P = 0.01). The mean Glasgow Coma Scales at emergency department admission was 6.87 ± 3.36. Except 1 patient who expired after cardiopulmonary resuscitation, Glasgow Coma Scales at 30-day of hospital discharge were 15 in 10 patients (71.4%), 14 in 1 patient (7.1%), 13 in 1 patient (7.1%), and 6 in 2 patients (14.2%). Seven patients (46.7%) developed delayed neurologic sequelae. Four patients showed mild types of delayed neurologic sequelae and 3 showed moderate to severe types of delayed neurologic sequelae. CONCLUSION: Most of patients underwent induced hypothermia had a good recovery from severe acute CO poisoning. Therefore, induced hypothermia may be considered as a possible treatment in severe acute CO poisoning.

Suction-assisted lipectomy has become an increasingly popular procedure, being one of the most frequently performed aesthetic procedures in Korea. Serious complications of suction-assisted lipectomy are uncommon but aesthetic problems are often troublesome. Here we report a patient with multiple abdominal masses composed of fat necrosis with fibrosis after suction- assisted lipectomy that was treated with excision. We also discussed and deduced the cause of its complication because plastic surgeons are liable to overlook this rare complication.

Mucosa-associated lymphoid tissue (MALT) lymphoma is a neoplasm with low-grade malignancy that arises from the MALT of various organs. Among the various MALT lymphomas, gastric MALT lymphoma is the most frequently reported, and it has been correlated with Helicobacter pylori infection. In contrast, duodenal MALT lymphoma is very rare, and a relationship with H. pylori has not been established. This case report describes a very rare case of MALT lymphoma arising in both the stomach and duodenum that regressed after eradication of H. pylori.

Liability to vascular trauma in orthopedic procedures results from the close relation between bones and vessels and complicated use of sharp instruments and retractors. Prompt diagnosis and management are mandatory to avoid high mortality and morbidity. We report 6 vascular injuries secondary to orthopedic procedures performed between 1994 and 1998. Two injuries occurred as a consequence of intramedullary nailing and Ilizarov external fixation of a femur fracture, one injury from lumbar laminectomy, one injury as a result of total hip replacement, one from hip flexion contracture release and the other one secondary to knee flexion contracture release. Injury occurred to three femoral arteries, one femoral artery and vein, one popliteal artery, and one iliac artery and IVC. Four vascular injuries required bypass grafts, division was done in AV fistula following disc operation. Conservative treatment was given to one vascular injury. There was no significant complication and death in our series except one case of graft infection that was revised with extra-anatomic bypass. The goal of management of vascular trauma that occurs during the orthopedic procedure is to save the limb and even the life. Urgent management based on knowledge of vascular structure and skillful surgical technique are needed.

PURPOSE: Pseudomonas aeruginosa has emerged as one of the most problematic bacteria in modern hospital settings, and this organism is increasingly isolated as a nosocomial pathogen. Burn patients are particularly susceptible to Pseudomonas infection. Therefore, the accurate and sensitive microbiologic tests are needed for strict management of this prevalent microorganism. METHODS: A nested polymerase chain reaction test based on consecutive amplification of the lipoprotein genes, oprL and oprI, was designed and evaluated, in comparison with the conventional blood culture, for its ability to detect Pseudomonas aeruginosa in clinical materials of burn patients. RESULTS: Positive results of PCR based on oprL gene were observed only for Pseudomonas aeruginosa. All other bacteria (n=4) tested by this amplification method were negative. Also the lowest detection level was 1X101 bacteria per ml of blood samples. In addition, PCR afforded a significantly higher detection rate for Pseudomonas aeruginosa than the conventional blood culture technique in clinical materials of burn patients (25.9% vs. 8.6%). CONCLUSION: This study suggests that the nested PCR technique is highly specific and sensitive test for detectionof Pseudomonas aeruginosa, and therefore it may be a useful adjunct tool, in combination with other conventional techniques, for detection of Pseudomonas aeruginosa infection.

A case of symptomatic bilateral popliteal artery entrapment syndrome is reported. A twenty-one-year old male, a candidate of athlete, complained of coldness, weakness, pallor and cyanosis of right lower leg and intermittent claudication to both calves during walking or exercise for ten months. Studies revealed that the right popliteal artery was completely occluded, but the left popliteal artery was non-occlusive. An endarterectomy and onlay vein patch graft to the thrombosed and fibrotic right popliteal artery, and myotomies of bilateral medial heads of gastrocnemius muscle were done (May 20, 1998). Follow-up examinations for the last ten months showed a complete relief of symptoms with normal distal arterial flow. It is thought that even though the majority of patients present with unilateral calf claudication, the possiblity of bilateral problems need to be also considered.
