Although the incidence of intracranial multiple aneurysms are not low, the occurrence of multiple aneurysms more than three developing on the ipsilateral carotid artery is quite rare. We present a patient with five aneurysms on the left internal carotid artery. Four aneurysms arising from the left internal carotid artery underwent microsurgical clipping and wrapping, and remnant superior hypophyseal artery aneurysm was treated by using coil embolization. Incidence and risk factors for management of multiple aneurysms were investigated with the literature review.

Esophageal candidiasis is the most common disease among all candida infections of the gastrointestinal tract, and generally develops in immunocompromised patients. The prevalence of esophageal candidiasis has increased in patients undergoing antibiotic therapy, diabetes, adrenal dysfunction, alcohol intoxication, old age, esophageal injury, esophageal stasis, gastric surgery, and acid suppressive therapy. However, the overall prevalence is not higher than that of immunocompromised patients. Gastric candidiasis is uncommon because of the strong acidity of the gastric juices. The most common clinical setting for gastric candidiasis is in patients with neoplastic disease. However, there are some case reports suggesting an increase in the prevalence of gastric candidiasis after gastric ulcer therapy with surgery or acid suppressive agents. Delayed gastric emptying, increased intragastric pH, and reflux of the duodenal contents into the stomach are factors indicative of the pathophysiology of gastric candidiasis after gastric surgery. We encountered a case of aggravated esophageal candidiasis and the formation of a gastric yeast bezoar following a gastric outlet obstruction due to a duodenal stenosis. We herein report this case along with an overview of the relevant literature.

OBJECTIVE: To compare laparoscopic surgery with conventional abdominal surgery in patients with early stage endometrial cancer. METHODS: A retrospective review of 63 patients with early stage endometrial cancer managed between March 2003 and May 2005. Two groups were defined whether they had been treated by laparoscopy (case group: n=26) or by laparotomy (control group: n=37). We compared age, body mass index (BMI), hemoglobin change, operation time, number of pelvic lymph nodes, hospital stay, case with adjuvant treatment and recurrence between two groups. RESULTS: There was no statistical difference in characteristics (age, BMI, nulliparity, previous abdominal surgery, FIGO stage, histologic grade). between case and control group. In addition, there was no statistical difference in operation data and outcomes between two groups. Hemoglobin changes were 1.1 g/dL (case group) vs 1.7 g/dL (control group) (p=0.072). Operation time was 131 min vs. 115 min. The numbers of lymph nodes obtained were 8.7 vs 7.7 (right) 9.2 vs. 7.6 (left). Hospital stays were 8.4 vs. 9.2 days. Adjuvant treatment cases were 7 vs. 15. Recurrent case was one in each group. Two patients initially evaluated by laparoscopy were converted to laparotomy due to bleeding and adhesion. CONCLUSION: Laparoscopic surgery for treatment of early endometrial cancer is a safe and effective alternative to laparotomy . However, long-term survival and risk of recurrence have yet to be determined.

OBJECTIVE: Mammalian target of rapamycin (mTOR) is known to promote cell proliferation, survival, and resistance to radiation. The aim of this study was to determine whether mTOR expression was associated with survival and the response to radiation in patients with cervical cancer. METHODS: After reviewing 119 patients treated by primary radiotherapy for stage IIB-IVA cervical cancer, a case-control study was performed. The cases (n=12) with local recurrence or radiation failure after primary radiation therapy were selected. For each case, two controls that had no recurrence were selected. Using pretreatment paraffin-embedded tissues, the cytoplasmic expression of phosphorylated-mTOR (p-mTOR) was evaluated by immunohistochemistry. Staining was scored based on intensity (intensity score [IS] 0-3) and proportion (proportion score [PS] 0-100). The progression free survival (PFS) was defined from the end of treatment to the day of recurrence by imaging studies or biopsy. The staining distribution and PFS were compared between the two groups. The results were analyzed by the Student t-test, Mann-Whitney U-test, Fisher's exact test, and Cox proportional hazards regression model. RESULTS: The p-mTOR cytoplasmic expression was significantly associated with a poor response to radiotherapy (p<0.01). With respect to survival, a higher cytoplasmic expression of p-mTOR was associated with a worse outcome (p=0.02). The hazard ratio for recurrence or radiation failure was 6.18 for mTOR IS and 1.04 for mTOR PS (p<0.05 for both), indicating that the degree of p-mTOR staining correlated with the recurrence risk. CONCLUSION: High expression of p-mTOR was associated with radiation resistance; therefore p-mTOR may be a prognostic marker for response to radiotherapy in patients with cervical cancer.

OBJECTIVE: Lynch syndrome is a hereditary cancer syndrome that increases the risks of colorectal and gynecologic malignancies such as endometrial and ovarian cancer. Studies have shown that mutations in mismatch repair genes (MSH2, MSH6, and MLH1) are associated with Lynch syndrome. The aim of our study was to estimate the value of MSH2, MSH6, and MLH1 immunohistochemistry based on family history in a Korean sample. METHODS: Thirty six women with synchronous gynecologic tumors of endometrial and ovarian cancer were identified among patients being treated at our institution. Among them, 32 patients had tumor blocks (total 62 slides) available for analysis. According to a diagnostic algorithm, we performed immunohistochemistry analyses. Staining was scored based on intensity and proportion (negative or 0: intensity undetectable or minimal, proportion <5%; weak or 1+: intensity mild, proportion 5-30%; strong or 2+: intensity moderate to marked, proportion 30-99%). RESULTS: Among 32 eligible patients, 9 (28%) had a family history of cancer. Six patients (19%) were negative for MLH1; among them, four (4/6) were negative at both sites. Nine patients (28%) were negative for MSH2 or MSH6 at both sites or negative for both MSH2 and MSH6. Among these three patients showed negative staining for both sites. The three patients showing negative staining for MLH1, MSH2, and MSH6 at both sites with family history were considered to be the screening positive groups of Lynch syndrome. CONCLUSION: In this study, the frequency of Lynch syndrome associated immunohistochemical staining (MLH1, MSH2, and MSH6) group was estimated as 9% (3/32) among Korean women with synchronous gynecologic tumors.

OBJECTIVE: Hypoxia has been established as a key factor influencing the pathophysiology of malignant growth. Hypoxia-induced changes in gene expression are coordinated primarily by hypoxia inducible factor-1 alpha (HIF-1alpha) and HIF-2alpha. The purpose of this study was to determine whether or not HIF-2alpha expression is associated with survival and response to radiation in patients with cervical cancer. METHODS: After reviewing the medical records of 119 patients treated in our institution by primary therapy for stage IIB-IVA cervical cancer, we performed a case-control study. Cases (n=12) were selected from patients with local recurrence or radiation failure after primary radiation therapy with or without concurrent chemoradiation. For each case, we selected two controls from patients who had no evidence of local recurrence. Using pre-treatment paraffin-embedded tissues, we evaluated the expression of HIF-2alpha by immunohistochemistry. Staining was scored based on intensity (intensity score [IS], 0-3) and proportion (proportion score [PS], 0-100). The results were analyzed by the Student t-test, Mann-Whitney U test, Fisher's exact test, and Cox proportional hazards regression model. RESULTS: Cytoplasmic expression of HIF-2alpha, representing the degree of hypoxia, had a relationship with poor response to radiotherapy. The hazard ratio of recurrence was 1.71 for the HIF-2alpha IS (p=0.110) and 1.04 for the HIF-2alpha PS (p<0.001), indicating that the HIF-2alpha staining area correlates weakly with the risk for recurrence. CONCLUSION: The HIF-2alpha expression area may have an important role in radioresistance in patients with locally advanced cervical cancer. We conclude that a wider area of hypoxia predicts an increased probability of radioresistance.

PURPOSE: Acute aortic diseases, such as aortic dissection and aortic aneurysm, can be life-threatening vascular conditions. In this study, we compared outcomes before and after the implementation of a critical pathway (CP) for patients with acute aortic disease at the emergency department (ED). MATERIALS AND METHODS: This was a retrospective observational cohort study. The CP was composed of two phases: PRE-AORTA for early diagnosis and AORTA for prompt treatment. We compared patients who were diagnosed with acute aortic disease between pre-period (January 2010 to December 2011) and post-period (July 2012 to June 2014). RESULTS: Ninety-four and 104 patients were diagnosed with acute aortic disease in the pre- and post-periods, respectively. After the implementation of the CP, 38.7% of acute aortic disease cases were diagnosed via PRE-AORTA. The door-to-CT time was reduced more in PRE-AORTA-activated patients [71.0 (61.0, 115.0) min vs. 113.0 (56.0, 170.5) min; p=0.026]. During the post-period, more patients received emergency intervention than during the pre-period (22.3% vs. 36.5%; p=0.029). Time until emergency intervention was reduced in patients, who visited the ED directly, from 378.0 (302.0, 489.0) min in the pre-period to 200.0 (170.0, 299.0) min in the post-period (p=0.001). The number of patients who died in the ED declined from 11 to 4 from the pre-period to the post-period. Hospital mortality decreased from 26.6% to 14.4% in the post-period (p=0.033). CONCLUSION: After the implementation of a CP for patients with acute aortic disease, more patients received emergency intervention within a shorter time, resulting in improved hospital mortality.

Percutaneous transluminal coronary angioplasty(PTCA) has been widely applied in patients with coronary artery disease since 1977. Although coronary angioplasty has beeb shown to be safe and effective treatment strategy, acute closure & restenosis remain as major limitations of PTCA. Acute occlusion due to intracoronary thrombus accumulation during or immediately after coronary angioplasty is serious complication of PTCA, also, Intracoronary urokinase has been used to treat acute occlusion by intracoronary thrombus that complicated in PTCA and proved to be effective in restoring vessel preventing acute myocardial infarction. We report a case in which embolism of left anterior descending artery was complicated during angioplasty of left circumflex artery and managed with intracoronary infusion of urokinas.

Gastric cancer patients with acute disseminated intravascular coagulation experiences a rare but severe complication resulting in a dismal prognosis. We report a case of advanced gastric cancer complicated with disseminated intravascular coagulation with intractable tumor bleeding which was successfully treated with chemotherapy consisting of 5-fluorouracil and oxaliplatin. The patient was a 63-year-old man who complained of abdominal pain, melena, and dyspnea on 24 November 2010. We diagnosed stage IV gastric cancer complicated by disseminated intravascular coagulation. Gastric tumor bleeding was not controlled after procedures were repeated three times using gastrofiberscopy. With the patient's consent, we selected the 5-fluorouracil and oxaliplatin combination chemotherapy for treatment. After one cycle of 5-fluorouracil and oxaliplatin therapy, symptoms of bleeding improved and the disseminated intravascular coagulation process was successfully controlled. The primary tumor and multiple metastatic bone lesions were remarkably shrunken and metabolically remitted after eight cycles of chemotherapy. In spite of progression, systemic chemotherapy is effective in disease control; further, the patient gained the longest survival time among cases of gastric cancer with disseminated intravascular coagulation.

OBJECTIVE: To evaluate the clinicopathologic characteristics and prognostic factors of ovarian granulosa cell tumors. METHODS: Medical records of 113 patients presenting between January 1995 and December 2007 were retrospectively reviewed. RESULTS: One-hundred two patients had adult type disease, with a mean age of 46.2 years (range, 18 to 83 years) and a mean follow-up period of 54.7 months (range, 1 to 155 months). The distribution of FIGO stages was 86 patients at stage I, 11 at stage II, and 5 at stage III. During follow-up, ten patients recurred at a mean time of 48 months (range, 4 to 109 months). Among them, three patients died after a mean of 57 months (range, 25 to 103 months). In recurrence analysis, advanced stage (p=0.032) and presence of residual disease (p=0.012) were statistically significant, and age<40 years, premenopause and positive washing cytology were marginally significant (p<0.1). In multivariate analysis, stage was the only factor associated with recurrence; adjuvant chemotherapy and fertility-sparing surgery were not statistically significant. Among 36 patients with fertility-sparing operations, eight patients had nine pregnancies and delivered seven babies. Eleven patients had juvenile type tumors; the mean age was 20.0 years (range, 8 to 45 years) and the mean follow-up period was 69.8 months (range, 20 to 156 months). The distribution of FIGO stage was nine patients at stage I and two at stage III. There were no recurrences or deaths reported. Four patients had seven pregnancies and delivered six babies. CONCLUSION: Stage is the only factor associated with disease-free survival, and fertility-sparing surgery may be a treatment option for women with early-stage disease who want to retain fertility.
