Pleomorphic Adenoma of the Breast: A Diagnosis Using an Ultrasound-Guided Core-Needle Biopsy Case Report

Pleomorphic adenoma is a tumor rarely seen in the breast. To date, only about 70 cases have been reported in the literature. Many reports have used fine-needle aspiration biopsy in the preoperative diagnosis of these lesions. However, pleomorphic adenoma is sometimes mistaken for a malignant tumor because of its cytologic features. In this study, we present a 56-year-old woman with a palpable breast mass. Ultrasound indicated a 15 mm oval-shaped hypoechoic mass with complex echogenicity in the palpable region. Ultrasound-guided core needle biopsy (US-CNB) revealed a pleomorphic adenoma of the breast, which was confirmed through surgical excision. Although pleomorphic adenoma is rarely seen in the breast, results demonstrate the usefulness and accuracy of US-CNB in diagnosing pleomorphic adenoma of the breast.

The Importance of Clinical Indicators for Detecting Postoperative Complications Following Laparoscopic Sleeve Gastrectomy

PURPOSE: The significant drastic complications of performing laparoscopic sleeve gastrectomy (LSG) in morbidly obese patients are gastric staple line leakage and bleeding. The aim of our study is to evaluate the efficacy of the clinical data for detecting postoperative complications after LSG. METHODS: The study enrolled 150 consecutive patients who underwent LSG from January 2003 to July 2006. When abnormal data (heart rate > or = 10/min, or temperature > or = 7.5degrees C) was detected on postoperative day 1, then laboratory tests (blood, urine, chest X-ray and abdominal sonogram) and water soluble gastrografin UGIS were performed to detect the postoperative complications after LSG (group A). The patients who had normal postoperative clinical data (group B) were compared with group A. RESULTS: Of the 150 patients who underwent LSG, 9 patients (6%) had postoperative complications. Two patients had major complications: 1 case of leakage (0.6%) and 1 case of delayed bleeding (0.6%), and 4 patients had minor complications in group A. But no major complications were detected in group B (P 39degrees C). CONCLUSION: Evidence of tachycardia or a high body temperature may be useful to detect major complications after LSG. We also recommend performing laboratory test and UGIS when clinically indicated.

Adult Onset Still's Disease Misunderstood as Sepsis with Bile Peritonitis

Adult onset Still's disease (AOSD) is a rare systemic inflammatory disorder of an unknown etiology, and its major clinical manifestations include high spiking fever, polyarthralgia, salmon-colored evanescent rash and neutrophilic leukocytosis. We describe here a 41 year old woman with AOSD who presented with non-remitting high fever, polyarthralgia, sore throat, skin rash, splenomegaly, thrombocytopenia, neutrophilic leukocytosis, hyperferritinemia and coagulopathy with disseminated intravascular coagulation (DIC). The patient had a history of laparoscopic cholecystectomy due to acalculous cholecystitis prior to admission. We suspected sepsis due to bile peritonitis after the previous laparoscopic cholecystectomy. Yet we could not detect infectious organisms on the cultures or serologic studies. Finally, we suspected AOSD-associated hemophagocytic syndrome (HS). So, intravenous immunoglobulin and pulse methylprednisolone treatment brought about transient improvement of the fever and the neutrophilic leukocytosis, but the disease progressed and the patient expired due to acute renal failure. HS is a fatal cause of AOSD. If a patient has DIC and sepsis and these fail to respond to conservative treatment, then AOSD should be added to the differential diagnosis of sepsis and DIC.

Infected Urachal Remnants with Symtoms of the Acute Abdomen: The Differential Diagnosis & Proper Management

PURPOSE: Urachal anomalies are rare, but often give rise to a number of problems, such as infection, rupture, sepsis and malignant change. The abdominal manifestation of urachal remnants often prompts referral to general or urologic surgeons. Herein, our clinical experiences were analyzed and guide lines for the preoperative diagnosis and proper management of complicated urachal anomalies suggested. METHODS: Twelve cases of urachal cyst, who visited the surgery department of Pochon CHA university hospital between April 1, 1995 and December 10, 2002, were studied. Clinical data, including clinical manifestations, diagnostic modalities and treatment methods were reviewed. RESULTS: Of the twelve cases reviewed, nine were males and three were females with a mean age of 33.6 years. The most common clinical manifestation was abdominal pain (58%), followed by a palpable mass (25%). The accuracies of the diagnostic modalities were 60 and 37% for abdominopelvic computed tomography and abdominal ultrasonography, respectively. The preoperative diagnosis rate was 50%, with one case not even diagnosed during surgery. CONCLUSION: Persistent urachal remnants can present at any age, with a variety of clinical manifestations. Abdominal computed tomography is a reliable diagnostic tool, and additional diagnostic studies are not generally warranted. The early surgical treatment seems to be the best solution prior to the onset of complications that would expose patients to difficult surgical operations and protract hospitalization.

A Comparative Study on Residency Education in General Surgery / 한국의학교육

PURPOSE: The role of graduate medical education(GME) has become more important at the flood of knowledge and technical development. The korean board system in general surgery has a short history and has been developed mostly by the executive authorities rather than by autonomous civil organizations which is the case in america and europe. The aim and curriculum of our residency education is not yet well established, so that there requires the need to evaluate and analyze the training system of other well-established countries. METHODS: The structures of residency education and their characteristics in U.S.A., England and Germany were reviewed from the literatures and internet sites in terms of aims and objects of learning during the training period. The korean system was compared to these characteristics. RESULTS: Comparing the residency training programmes of U.S.A., Germany and England to our system there found some characteristic points as following that would be recommendable to be adopted for the renewal of our training programme. 1) Autonomous civil organizations endeavor for the regulations of educational goal, requirements and their accreditation. 2) The understanding of basic sciences that provide the fundamental principles of surgery was emphasized during the education. 3) Modern surgical techniques as a part of minimal invasive surgery can be easily acquired during the training course. 4) Participation in emergency medicine and intensive medicine was almost mandatory. 5) Interdisciplinary training and effective rotation schedule were highly recommended. All these characteristics could be actively integrated into our education, if we elaborate more well-established educational goal and curriculum for the residentship.

The Antiproliferating Effect of Diallyl Disulfide from Garlic on the Human Breast Cancer Cell Line (MCF-7) / 한국유방암학회지

PURPOSE: Diallyl disulfide (DADS), an organosulfur compound in garlic, has been reported to be effective in inhibiting the growth of several human tumor cell lines. The aim of this study was to determine whether DADS induced growth inhibition in MCF-7 breast cancer cell lines and to understand the molecular mechanism by which DADS acts. METHODS: MCF-7 cell lines were incubated with various concentrations of DADS for various time intervals and the cytotoxicity was determined by MTT assay. We examined the changes of intracellular proteins related to apoptosis, such as bcl-2, bax and PARP in cells treated with DADS. To study the expression level of bcl-2 and bax, which serve as modulators of apoptosis, we performed RT-PCR and western blot analysis. RESULTS: MCF-7 cells treated with DADS led to the suppression of viability and proliferation in both a time and concentration dependent manner. Microscopic observation revealed typical features of apoptosis in the DADS-treated cells, further verified in nuclear DAPI staining. Flow cyto-metry analysis with FITC-annexinV and propidium iodide (PI) demonstrated that the apoptotic cell population with AnnexinV+/PI- increased dramatically from ~0.8% to ~75% after 24h exposure to 500 microM DADS in MCF-7 cells. Cell cycle analysis demonstrated that the number of apoptotic cells increased with the increasing time of the DADS treatment. Additionally, thermore, we investigated the effects of DADS on apoptosis related gene expression in MCF-7 cells. PARP cleavage was markedly increased in the DADS treated cells with time. This result indicated that DADS induced the caspase-dependent apoptotic pathway. We also found down-regulation of bcl-2, however no significant change of Bax expression was observed after DADS treatment. Conclusion: Taken together, these results indicate that DADS induces apoptosis by activating a caspase pathway involving the activation of Bcl-2 but not of Bax. Our findings suggest chemotherapeutic potentials of DADS in human breast cancer.

Bile Carcinoembryonic Antigen in Colorectal Cancer

PURPOSE: Serum level of carcinoembryonic antigen (CEA) is clinically one of the prognostic factors in the follow-up evaluation of the colorectal cancer (CRC) patient. It has been recently suggested that the bile CEA level is also useful in early detection of the liver metastasis of colrectal cancer. If the bile CEA is also correlated with the cancer progression or prognosis like as serum CEA, it will be another useful clinical parameter in the evaluation and treatment of CRC patients. Therefore this study is aimed to reveal the correlation of the bile CEA with the progression of tumor and to estimate the possibility of bile CEA as a useful clinical parameter. METHODS: Preoperative serum levels of CEA were measured in 58 patients of CRC who were operated in Pundang CHA hospital. The levels of bile CEA were also checked with the aspiration of bile in gall bladder at laparotomy. The positive value of CEA was settled as more than 5ng/ml. RESULTS: The 58 patients were classified into 29 cases of Dukes'AB group, 23 cases of Dukes'C group & 6 cases of Dukes'D group. The positive rates of serum CEA were 24.1% in AB group, 30.4% in C group & 66.7% in D group, and those of bile CEA were 44.8%, 56.5% & 83.3% individually. When group C was also divided into N1(13 cases) & N2 (10 cases) groups according to the number of the metastatic lymph nodes, serum & bile CEA positive rates were 15.4% & 46.1% in N1 group, and 50% & 70% in N2 group. Both of serum & bile CEA levels were all positive and markedly elevated in 4 hepatic metastasis cases of group D. CONCLUSIONS: Positive rate of bile CEA was increased according to the progression of tumor stage. Marked elevation of bile CEA was especially noted in liver metastatic cases. Therefore bile CEA can be considered as a clinical parameter in evaluation of cancer progression & prognosis like as serum CEA, and also as a useful indicator of hepatic metastasis.

Comparative Review of Perianal Sinus & Fistula in Ano

PURPOSE: A fistula in ano is a granulating track between the anorectum and the perianal region or perineum. A typical fistula may consist of the track, the primary (internal) opening and secondary (external) opening. Its hallmark is frequent discharge through external opening. Sometimes this track become occluded and a sinus remains. Therefore abscence of an external opening should not be taken as evidence that there is no fistula, and then this study is aimed to make clear perianal sinus as another form of fistula in ano. METHODS: This study is a clinical analysis of 17 patients with perianal sinus, who were treated at the Department of General Surgery of Pundang-CHA hospital from June, 1995 to December, 1998. As comparative group, 91 patients of typical fistula in ano were also taken in same period. RESULTS: The ratio of male to female was 4.6:1 in sinus group, 4.1:1 in fistula group. The prevalent ages were in the third decade in both group. The main symptoms of sinus group were a palpable mass (94.1%), pain & discomfort (35.3%) but that of fistula group were purulent discharge (87.9%) and pain (28.6%). The most frequent duration of illness was 6 months~1 year (52.9%) in sinus group, within 6 months (40.7%) in fistula group. The distributions of sinus size were 7 cases (41.2%) in 2 cm. The most common type was intersphincteric in both group. The operative procedures included excision with fistulectomy in 4 cases (23.5%), lay open of sinus with fistulotomy in 11 cases (64.7%), seton procedure in 2 cases (11.8%). The mean hospital stay was 5.0 day in sinus group, 4.9 day in fistula group. CONCLUSIONS: There was no distinct difference in the clinical features or characteristics between the both groups, therefore perianal sinuscould be taken as fistula in ano and treated similar procedures.

A Case of Malignant Gastric Stromal Tumor / 대한소아혈액종양학회지

As leiomyosarcomas of smooth muscle origin are rare tumors found in adults, they are even more uncommon among children. Therefore, most of the existing literatures concerning pediatric leiomyosarcomas has been limited to case reports. More recently, ultrastructural and immunohistochemical studies revealed that some tumors may have properties more suggestive of nerve cells or vascular endothelial cells, rendering the gastrointestinal stromal tumor a more popular term. We experienced a 13 year old boy who was diagnosed and treated as iron deficiency anemia. Even after iron therapy, he had persistent anemia and endoscopic examination revealed a huge mass in the gastric cardia. Proximal gastrectomy was performed with margins free of tumor. The tumor cells showed high mitotic activity suggesting malignant nature. The immunohistochemical staining was positive for smooth muscle actin while negative for S-100 protein. Brief review of the literatures are presented.

Exposure to lonizing Radiation in the Emergency Department from Performed Portable Radiographs

To accurately assess the potential hazard of exposure to ionizing radiation from portable radiographs taken in the emergency department,.a study was performed to measure such radiation at different distances from the edge of an irradiated field during portable cervical spine, portable chest radiographs, and portable anteroposterior pelvis radiographs. For all three types of portable radiographs, radiation exposure is high at the edge from the beam. However, radiation exposure is deceased at 20, 40, 80, 160cm away from the beam. This study confirms and supports the evidence that although radiation exposure is dependent on distance from the primary radiograph beam, exposure in the ED is minimal. Medical personnel should not have to leave a patient care area for fear of undue acute and chronic radiation exposure while portable radiographs are performed in the ED. By using protective garments and standing appropriate distance away from the patient, continuous patient care can be maintained while portable radiographs are taken in the ED.

The Expression and Correlation of Cyclin E, P21WAF1Protein and P53 Variant Protein in Colorectal Adenoma and Carcinoma

Cyclins are proteins that activate different cyclin-dependent kinases(CDKs) and promote the cell cycles. Their correlations with several human cancers have been identified. Cyclin E, as one of G1 cylins, produces DNA replication through the progression of cell cycle G1 --> S phase. In contrast, cyclin-dependent kinase inhibitors(CDKI) bound with cyclin E-cdk2 complex control the cell cycle and inhibit the cell proliferation. P21(WAF1) proteins, which are CDKIs, are transcripted by a p53 gene and participate in the cell cycle inhibition. Variant p53 proteins produced by a mutated p53 gene lose the ability to control of the cell cycle resulting in cell proliferation. This study is aimed to reveal the expressions of cyclin E, p21(WAF1) protein, p53 variant protein in colorectal adenomas and carcinomas, and also reveal their correlations in the process of carcinogenesis. Twenty-one colorectal adenomas or adenomatous polyps, and thirty colorectal carcinoma tissues were obtained by operative resections or endoscopic polypectomies. Immuno histochemical stains of the above-mentioned three proteins and a statistical analysis of their correlations were made. The results were as follows: 1. P21 proteins were expressed in the upper-one third layer of all normal colonic mucosa, but cyclin E and variant p53 protein were not identified. 2. Cyclin E was expressed in 23.8% of adenomas and 76.7% of carcinomas. Variant p53 protein was expressed in 71.4% of adenomas and 83.3% in carcinomas. The degree of positivity of variant p53 expression was correlated with cancer staging. P21 protein was expressed in all adenomas, similar to normal mucosa, but was not expressed in 43.3% of carcinomas. 3. Expression of cyclin E was increased as to the positivity of variant p53 proteins but the correlations of p21 proteins and cyclin E, and p21 proteins and variant p53 proteins were not identified. Cancer staging was not correlated with the expressions of the three proteins. In conclusion, it can be thought that the overexpression of cyclin E and variant p53 proteins, and the loss of p21 proteins are related with the colorectal carcinogenesis. We can also identify the relationship of cyclin E and variant p53 proteins.

Immunohistochemical Analysis of the Expression of Cathepsin D in Human Gastric Adenocarninoma / 대한암학회지

PURPOSE: Cathepsin D is an acidic lysosomal proteinase involved in intracellular protein turnover. Increased levels of this enzyme have been reported to be indicators of aggressive tumor behavior in some human tumors. In gastric cancer, increased expression of cathepsin D has been reported to be an independent prognostic factor. MATERIALS AND METHODS: We used standard immunohistochemical techniques on formalin- fixed, paraffin-embedded tissues to examine the expression of the cathepsin D in fifty five gastric adenocarcinomas. And we compared these with other indicators of aggressive tumor behavior including stage of disease, tumor size, lymphatic invasion, neural invasion, Lauren classification, disease recurrence and survival. RESULTS: Positive granular cytoplasmic staining for cathepsin D was detected in 100% of the tumors and strongly positive staining was found in 53%. However, the intensity of the staining varied from cell to cell in the same carcinoma tissue as well as among samples. Positive staining also was seen in normal foveolar epithelial cells, parietal cells, macrophages and ganglion cells. Our results did not show any correlation between the expression of cathepsin D and other indicators of aggressive tumor behavior. But the group having more intensely stained margins showed the tendency to frequent lymphatic invasion. CONCLUSION: We conclude that the results obtained using polyclonal antibodies to cathepsin D do not support the prognostic usefulness of immunohistochemical analysis of this proteinase in tumor cells in human gastric adenocarcinoma, but this study may offer some useful indicator for further pathophysiological studies on gastric adenocarcinoma.

Multimodality Treatment for Hepatolinthiasis

Hepatolithiasis is characterized by high treatment-failure and recurrence rates. In the past, surgery played a major role in the management of this disease, but the development of percutaneous transhepatic cholangioscopy and lithotripsy has played an important role in the treatment of this disease. Therefore, we undertook this prospective study to assess the effects of a systematic complementary approach of surgical and therapeutic endoscopic treatments for hepatolithiasis. We evaluated our results for 56 patients with intrahepatic stones treated by a percutaneous transhepatic cholangioscopic approach and by a surgical approach.The rate of complete stone removal was 94.4%(51/54). Twenty-five cases were treated with only a choledochoscopic approach, and 31 cases with a complementary approach(a definitive surgical approach after the choledochoscopic approach). There was no procedure or operative mortality. Because the improvement in the stone clearance rate was evident for the systematic complementary approach, this approach is recommended, when possible.

The Expression of DCC Protein in Colorectal Carcinomas

Colorectal cancer is one of the malignant tumours of which molecular genetic alterations have been much unveiled among the human cancers. In the multi-stepwise process to the carcinogenesis, it has been recently revealed that the neoplastic growth is originated either from the activiation of oncogene through its mutation, rearragement and amplification, or from the inactivation of the tumour suppression gene through its mutation and deletion. DCC(Deleted in colon cancer) protein is the product of DCC gene, the representative of tumor suppressor genes. The alteration of DCC protein may be related with the aggressiveness of carcinoma and metastasis. As a result, the prognosis of the cancer may be also thought to be affected. Now the prognosis of colorectal cancer mainly depends on pathologic staging, but there are some variations of survival and recurrence among the patients in same stage. Then this study is aimed to reveal the significance of alteration of DCC protein as an independent factor related to prognosis. Twenty three cancer tissues were obtained from the rejected specimens of colorectal carcinomas. We exacted the DCC gene products in the cancer tissues by the methods of immunohistochemical stains and Western blots. We also analyzed the relationships between the alteration of DCC proteins and the status of regional lymph node metastasis or the serum levels of CEA's(carcinoembryonic antigen). As results, we found the abscence or very scanty stains of DCC protein by Western lot in 14 cancer tissues of available 19 cases, but there were all negative responses in immunohistochemical stains. In contrast with above results, there were all positively stains of DCC proteins in corresponding 23 normal colorectal tissues by both the methods. There was no significantly statistical relation between the alteration of DCC proteins and the status of regional lymph node metastasis or the serum level of CEA. In conclusion, we can confirm that the DCC proteins are abscent or very scanty in colorectal cancer tissues and that may be related with the process of carcinogenesis. But the role of DCC protein loss as an independent prognostic factor was not found in this study.

Early Prognostic Significance of Lymphatic Vessel Invasion in Gastric Cancer

In gastric cancer, the significance of lymphatic invasion as a prognostic factor is controversial. This study was performed to investigate the significance of lymphatic invasion as a prognostic factor in early results of gastric cancer after gastrectomy. We had been prospectively analyzed 362 consecutive patients resected from June 1994 to June 1996 in the Department of Surgery, Ajou University Hospital. Grading of the lymphatic invasion was determined by pathologists according to the JRSGC classification. The difference in the survival rate between the ly0 group and the ly1 group was statistically insignificant, so we only used ly2 and ly3 as the risk group. The prognostic values of lymphatic invasion as a single parameter for survival and early recurrence were determined by using univariate and multivariate analyses. Lymphatic invasion was observed in 90 (24.9%) of the 362 gastric cancer cases, and ly2 or ly3 were 66 (18.3%)cases. The incidence of ly> or =2 steadily increased with advancing TNM stage : stageI, 9/124 (7.3%); stageII, 5/50 (10.0%); stageIII, 24/111 (21.6%); stageIV, 28/78 (35.9%). The incidence of ly> or =2 was significantly correlated with other prognostic factors such as lymph node metastasis, the depth of the primary tumor, and the stage (p or =2 and 90.9% in patients with ly or =2 group (p or =2) as an independent prognostic factor (p=0.0008, Exp(B)=3.55). The cummulative recurrence free rate determined by the Kaplan-Meirer method was 78.7% in the ly> or =2 group and 90.54% in the ly or =2 group (p=0.0055). Therefore lymphatic invasion with ly2 or ly3 grade is an independent prognostic factor that is associated with poor prognosis for early results after gastrectomy. In grading of lymphatic invasion by gastric cancer, simple differentiation of whether lymphatic invasion is present or not was insignificant in the results of our study. In the future, the grade of lymphatic invasion in gastric cancer should be carefully classified by pathologists.

Carotid Body Tumors

Carotid body tumor is relatively rare neoplasm of the extra-adrenal paraganglion system. We have experienced two cases of carotid body tumors and successfully resected without any complication. Pre-operative intravascular embolization of the major arterial feeders was used. The cases and literatures were briefly reviewed.
