PURPOSE: To investigate the therapeutic effectiveness of ultrasound (US)-guided trigger point injection for myofascial trigger points (MTrPs) in the internal rotator muscles of the shoulder in post-mastectomy patients. MATERIALS AND METHODS: This pilot study was a non-controlled, prospective, clinical trial. Nineteen post-mastectomy patients with a diagnosis of at least one active MTrP in the subscapularis and/or pectoralis muscles were included. We performed trigger point injections into the subscapularis muscle deep behind the scapula as well as the pectoralis muscle for diagnostic and therapeutic purpose by the newly developed US-guided method. RESULTS: Visual analogue scale and range of motion of the shoulder for external rotation and of abduction showed significant improvement immediately after the first injection and 3 months after the last injection compared with baseline (p<0.05 for both). Duration from onset to surgery and duration of myofascial pain syndrome in the good responder group were significantly shorter than in the bad responder group (p<0.05). Patients did not report any complications related to the procedure or serious adverse events attributable to the treatment. CONCLUSION: In post-mastectomy patients with shoulder pain, US-guided trigger point injections of the subscapularis and/or pectoralis muscles are effective for both diagnosis and treatment when the cause of shoulder pain is suspected to originate from active MTrPs in these muscles, particularly, the subscapularis.

PURPOSE: Polypoid lesions of the gallbladder have a range of causes. A problem exists in the selection of patients for surgery. This study examined the usefulness of laparoscopic cholecystectomy, suspected risk factors and plan of patients with gallbladder polyps. METHODS: This study examined 57 patients who underwent laparoscopy cholecystectomy with gallbladder polyps. All patients had been diagnosed preoperatively by ultrasound and abdominal computed tomography between October 2001 and October 2010. Preoperative radiologic diagnosis, age, gender, symptoms, size of polyps, number, concurrent gallstones and histological diagnosis of the polyps as well as the postoperative complications were reviewed retrospectively. The operation indications were polyps >10 mm, age above 55 years, symptomatic polyps, coincidence of a stone, focal thickening of gallbladder wall and detection during other operations. RESULTS: The number of each type of polyp lesion of the gallbladder was as follows: 26 cases (45.6%) had cholesterol polyps, 2 cases (3.6%) inflammatory polyps, 1 case (1.7%) mucosal lymphoid follicles, 12 cases (21.1%) adenomatous polyps, 1 case (1.7%) adenocarcinoma. Non-neoplastic and neoplastic polyps accounted for 50.9% and 22.8%, respectively. Forty-eight cases had an accepted operative indication and underwent surgery. The nine other cases also underwent surgery. Among those with operative indications, 27.1% had neoplastic polyps. Of the patients who had non-indication operative surgery or polyps <5 mm in size, there were non neoplastic polyps in any cases. Two of the patients developed complications; wound infection (1 case), and common bile duct obstruction (1 case). CONCLUSION: Observation and careful surgery is necessary for patients with polyps <5 mm in size, and who do not have accepted operative indications. Laparoscopic cholecystectomy can be considered an adequate treatment for patients with accepted operative indications.

PURPOSE: To evaluate of the role in carcinogenesis of p53 over-expression and bcl-2 inhibition in early gastric and advanced gastric cancers, we investigated the immunohistochemical tissue status of 31 primary early gastric-cancer patients and 31 primary advanced gastric-cancer patients. METHODS: DO7, the monoclonal antiserum to the P53 protein, and clone 124, the monoclonal antibody to the bcl-2 protein, were used for the immunohistochemical analysis of the 31 surgically resected primary early gastric cancer specimens and the 31 surgically resected advanced gastric-cancer specimens. The expressions were scored and divided into negative, positive, low expression, and overexpression. RESULTS: The clinicopathologic parameter; tumor depth of invasion, histologic type, and differentiation, were not related with the expression status of p53 or bcl-2. Of the 31 primary early gastric-cancer patients, 14 exhibited p53 overexpression and 16 showed negative the bcl-2 expression; 5 cases had both p53 overexpression and negative bcl-2 expression. Of the 31 advanced gastric cancer patients, 19 showed the p53 overexpression, and negative bcl-2 expression, 15 exhibited both p53 overexpression and negative bcl-2 expression. CONCLUSION: These results suggest that cell cycle alteration and apoptosis control by p53 and bcl-2 may play roles in the carcinogenesis of gastric cancer. However, there are many other mediators that may facilitate carcinogenesis. This study proved that bcl-2 is a valuable prognostic factor.

PURPOSE: In about 1% of cases, incidental gallbladder cancers (iGBC) are found after routine cholecystectomy. The aim of this study is to compare clinical features of iGBC with benign GB disease and to evaluate factors affecting recurrence and survival. METHODS: Between January 1998 and March 2014, 4,629 patients received cholecystectomy and 73 iGBC patients (1.6%) were identified. We compared clinical features of 4,556 benign GB disease patients with 73 iGBC patients, and evaluated operative outcomes and prognostic factors in 56 eligible patients. RESULTS: The iGBC patients were older and concomitant diseases such as hypertension and anemia were more common than benign ones. And an age of more than 65 years was the only risk factor of iGBC. Adverse prognostic factors affecting patients' survival were age over 65, advanced histology, lymph node metastasis, and lymphovascular invasion on multivariate analysis. Age over 65 years, lymph node involvement, and lymphovascular invasion were identified as unfavorable factors affecting survival in subgroup analysis of extended cholecystectomy with bile duct resection (EC with BDR, n = 22). CONCLUSION: Prior to routine cholecystectomy, incidental GB cancer should be suspected especially in elderly patients. And advanced age, lymph node metastasis, and lymphovascular invasion are important prognostic factors in EC with BDR cohorts.

PURPOSE: In spite of preventive measures and excellent prognosis with immediate treatments, drowning and drowning- related injuries remain as one of the leading causes of accidental death in Korea. However, abundant statistical data for drowning has yet to be collected. Thus, this study aimed to describe the epidemiologic characteristics of drowning in terms of demographic characteristics, geopolitical factors and socio-economic status. METHODS: This study was conducted with drowning patients who either visited hospitals or died between January 2001 and December 2003. Of these patients, we enrolled individuals registered for such coverages as automobile insurance, national health service and work injury insurance and we reviewed death records reported to the Korea National Statistical office. NISS (New Injury Severity Scale) and EMR-ISS (the Excessive Mortality Ratio -adjusted Injury Severity Score) values were calculated for each patients and the results were classified 4-into four different severity groups. After analysis, we drew conclusions in terms of year, gender, age, region, insurance type, daily rate of incidences and severity. RESULTS: The incidences of drowning-related injury were 2,486 in 2001, 2,364 in 2002, and 2,595 in 2003 (average of 2,482). The average annual death were 1,954. Victims were more likely to be male and especially high incidence rates were found for two groups: (1) Children aged 5-9 years, (2) Adults aged 40 and older. Seoul and Gyeonggi had the largest total numbers of injury cases, while JeJu had the highest per capita incidence rate (106 per 1,000,000 population). The seasonal distribution of incidence rates showed that predictably, incidents were most frequent between the beginning of July and September. CONCLUSION: The average number of incidents was 55.73 per 1,000,000 population, which constitutes approximately 0.02% of all injuries. Based on this data, we recommand continuing studies and further evaluations in order to develop specific measures to combat drowning.

We report a case of breast gigantism in a patient with Wilson's disease treated with penicillamine. A 19-year-old female with alleged Wilson's disease visited our hospital due to diffuse enlargement of both breasts. She had been treated with penicillamine 1,000 mg/day since her age of 15 after diagnosis of Wilson's disease. At the initial presentation, there were diffuse skin thickenings in both lower inner breasts and huge lesion which replaced almost all the breast parenchyma. After gun biopsy and excision for tissue diagnosis, fibroadenoma with ductal epithelial hyperplasia was diagnosed. Although daily dose of penicillamine was lowed to 500 mg/day, her symptom progressed. After 1 year of follow up, she and her parents strongly wanted to remove her breasts because of distorted body shape and weight of breasts. The patients underwent subcutaneous mastectomy with the designed incision of the reduction mammoplasty for the future mammoplasty. Although the breast gigantism is a rare side effect of penicillamine, female patients should be followed up cautiously for the possible change of breasts. Because penicillamine is no more the first choice for Wilson's disease, it would be better to avoid using penicillamine for Wilson's disease patients especially for the young females.

PURPOSE: To evaluate the independent prognostic value of Ki-67 in lymph node-negative breast cancer and the usefulness of Ki-67 when it combined with St. Gallen classification as a guidance of adjuvant chemotherapy for node-negative cancer. METHODS: We retrospectively reviewed the data of 534 patients with lymph node-negative breast cancer who underwent curative surgery between 1998 and 2001 at our institution. Patients were classified according to the guideline of risk groups of St. Gallen consensus and the level of Ki-67 expression. Distant metastasis-free survival (DFS) rates were compared between groups. RESULTS: With a median follow-up of 55 months, the overall 5-year DFS rate was 91.5%. The 5-year DFS rates for patients with high and low Ki-67 tumors (cut-off value: > or = 10%) were 84.6% and 93.7%, respectively (p < 0.001). In a Cox regression model involving potential prognostic factors, high Ki-67 expression could independently predict the risk of distant recurrence (odds ratio = 2.0 [95% confidence interval, 1.03-3.93]). The 5-year DFS rates for patients with average and minimal risk group of St. Gallen classification were 89.3% and 97.5%, respectively. The average risk group was further divided into two subgroups with significantly different prognosis according to the Ki-67 expression (DFS rate: 84.2% vs. 91.5%; p = 0.007). CONCLUSIONS: Ki-67 was an independent prognostic factor in lymph node-negative breast cancer and the combination of Ki-67 expression and the St. Gallen classification could provide a more useful therapeutic guideline for lymph node-negative breast cancer patients.

PURPOSE: We conducted this retrospective epidemiological study to assess the incidence and severity of lower extremity injuries in Korea METHODS: For this study, we retrospectively reviewed nationwide lower-extremity injury data compiled from 2001 to 2003 based on the National Injury Database, what included National Health Insurance Corporation (NHIC), Car Insurance, and Industry Insurance data. Data were standardized in terms of demographic characteristics, region, and socioeconomic status by using NHIC data. To assess the degree of the injuries, we used the Modified Abbreviated Injury Scale (MoAIS), what has been changed from the International Classification of Disease-10 (ICD-10) code. By using the Excess Mortality Ratio-adjusted Injury Severity Score (EMR-ISS), we classified the degree of severity into four categories: mild, moderate, severe and critical. RESULTS: From 2001 to 2003, lower extremity injuries increased slightly, with a yearly average of 2,437,335. Insurance data should that lower-extremity injuries were the most common, followed by upper-extremity injuries. Significant difference were seen in the numbers of lower extremity injuries based on gender and age. As for provinces, Seoul and Gyeongi provinces had the highest numbers of cases. Junlabukdo had the highest rate of 55,282 cases per 1 million people for standardized gender and population. The annual incidence of the insured patients with lower extrimity injuries was higher than the employer's medical insurance contributions to the medical insurance program. Daily cases occur most often in May and June, with the lowest occurrences being in January and February. CONCLUSION: The result of this study shows that lower extremity injuries comprised common cause of all injuries. In addition, differences associated with gender, location and socioeconomic status were observed. Further studies are needed to find reasons and then this knowledge will allow strategies to prevent the lower extremity injuries.
