BACKGROUND & METHODS: Approximately 10% of the essential hypertensive patient have overt proteinuria due to renal target organ damage, which indicates poor prognosis. Recently microalbuminuria has been prove to be a good early predictor for renal damage in patients with diabetes or hypertension. Some authors reported that near 40% of the essential hypertensives have microalbuminuria. To determinate prevalence of microalbuminuria in Korea essential hypertensives, 24-hr ambulatory blood pressure monitoring and radioimmunoassay to detect BP and UAER were performed after 4 weeks wash-out period in 137(78 hypertensive and 54 normotensive) consecutive cases. RESULTS: Among 78 hypertensives, overt proteinuria was seen in 8.97%(7/78). And prevalence of microalbuminuria were 29.4%(23/78) in hypertensives and 16.7%(9/54) in normotensives. Urine microalbumin excretion rate(UAER) was significantly correlated with mean arterial pressure(MAP) in total subjects(r=0.286, p=0.0012), but not in total hypertensives(r=0.135, p=NS) or in hypertensives with UAER(r=-0.098, p=NS).UAER of female hypertensives was increase than that of male hypertensives(13.17+/-16.28microg/min vs 22.87microg/min, p=0.027). CONCLUSION: Prevalence of microalbuminuria in Korean hypertensives was relatively lower then other reports. Overt proteinuria was noted in 8.97% of the hypertensives which is same prevalence as other countries. Moreover MAP was well correlated with UAER in total subjects. Further evaluation should be done to detect exact role of UAER in hypertensives as an early predictor for renal target organ damage.

PURPOSE: To describe our initial experience with a novel method of adenoma retrieval using a pneumovesicum (PNV) after Holmium laser enucleation of the prostate (HoLEP). METHODS: From January 2016 to April 2018, a total of 93 consecutive patients treated with HoLEP were enrolled in this study. For tissue morcellation, we used the PNV morcellation technique for an initial series of 21 patients and the conventional technique (Lumenis VersaCut) for a consecutive series of 72 patients. We compared efficiency and safety between the novel technique and the traditional technique. Subgroup analysis was performed to assess the effectiveness of the current technique in the large prostate (>70 mL). RESULTS: There were significant differences in mean age and prostate volume between the 2 groups. However, there were no significant differences in the baseline characteristics and preoperative parameters in the subgroup analysis of large prostates (>70 mL). The mean morcellation efficiency was higher (8.50±1.94 minutes vs. 1.76±0.45 minutes, P<0.05) and the time of morcellation (7.81±1.25 minutes vs. 34.04±11.14 minutes, P<0.05) was shorter in the PNV group. Moreover, there were no significant differences between groups in hospitalization period (2.62±1.10 days vs. 2.90±1.26 days, P=0.852) and any other postoperative events, including recatheterization, reoperation, clot retention, and urethral stricture (P-value range, 0.194–0.447). In the PNV group, there were some cases of procedure-related complications, including postoperative extravesical leakage (5th case), clot retention (8th case), and recatheterization (9th case). CONCLUSIONS: This method has a higher tissue retrieval efficacy, with the advantage of excellent visibility compared to conventional morcellation. The current method can be applied when a transurethral morcellator is out of order or cannot be used.

PURPOSE: The HER-2 oncogene plays a role in cellular oncogenic transformation, and is related to the aggressive tumor behaviour. Several studies have addressed the prognostic and predictive roles of the HER-2 status in gastric cancer; however, the HER-2 gene has not been used as a therapeutic target, as the opinions relating to its prognostic role are controversial. METHODS: Between January 1994 and December 1997 (1995 group), 192 patients who underwent a curative resection for a gastric adenocarcinoma at St. Mary's Hospital, College of Medicine, The Catholic University of Korea, were retrospectively reviewed from their paraffin embedded tissues and medical records. One hundred and twenty-seven patients, with the same characteristics and operated on between January and December 2002 (2000 group) were compared. The expression of HER-2 was analyzed by means of immunohistochemistry, with regard to the clinicopathological features and survival rate. RESULTS: The average ages of patients in the 1995 and 2000 groups were 56.3 and 59.1 years, respectively. In the 1995 group, 40.1, 26.5, 24.0 and 9.4%, had stage I, II, III and IV diseases, Whereas, in the 2000 group, these figures were 57.5, 18.1, 19.7, and 4.7%, respectively. The expression of HER-2 was positive in 12/192 patients (6.3%) in the 1995 group, and in 7/127 (5.5%) in the 2000 group. There was no relation between the overexpression of HER-2 and the pathological findings. However, the 5-year survival rates of patients with negative and positive HER-2 expression were 91.7 and 75.0%, in stage I and II gastric cancers, respectively. There was a significant difference in the survival rates between the two groups (P=0.010). CONCLUSION: HER-2 overexpression is an early event in gastric cancers, appearing at all stages of the disease, and is related to the poor prognosis of stage I, and II diseases. This fact is thought to be the basis of monoclonal antibody treatment and chemotherapy following a surgical operation for early gastric cancer.

PURPOSE: This study aimed to evaluate the clinicopathological characteristics of pregnancy-associated breast cancer (PABC) in comparison with non-pregnancy associated breast cancer (non-PABC). METHODS: A total of 344 eligible patients with PABC were identified in the Korean Breast Cancer Society Registry database. PABC was defined as ductal carcinoma in situ, invasive ductal carcinoma, or invasive lobular carcinoma diagnosed during pregnancy or within 1 year after the birth of a child. Patients with non-PABC were selected from the same database using a 1:2 matching method. The matching variables were operation, age, and initial stage. RESULTS: Patients with PABC had significantly lower survival rates than patient with non-PABC (10-year survival rate: PABC, 76.4%; non-PABC, 85.1%; p=0.011). PABC patients had higher histologic grade and were more frequently hormone receptor negative than non-PABC patients. Being overweight (body mass index [BMI], ≥23 kg/m²), early menarche (≤13 years), late age at first childbirth (≥30 years), and a family history of breast cancer were more common in the PABC group than in the non-PABC group. Multivariate analysis showed the following factors to be significantly associated with PABC (vs. non-PABC): early menarche (odds ratio [OR], 2.165; 95% confidence interval [CI], 1.566–2.994; p<0.001), late age at first childbirth (OR, 2.446; 95% CI, 1.722–3.473; p<0.001), and being overweight (OR, 1.389; 95% CI, 1.007–1.917; p=0.045). CONCLUSION: Early menarche, late age at first childbirth, and BMI ≥23 kg/m² were more associated with PABC than non-PABC.

Disseminated intravascular coagulation (DIC) is the result of a severe underlying disorder that initiates massive activation of the coagulation system. We report an unusual case of 79-year-old man who developed DIC after tooth extraction in abdominal aortic aneurysm. He was referred to our hospital because of persistent bleeding after tooth extraction. Physical examination indicated a pulsating mass in abdomen. Abdominal computerized tomography (CT) scan revealed 70 mm diameter aneurysm of the abdominal aorta, extending from the renal infrahilar level to the common iliac artery, and his coagulation profile showed the features of DIC by revealing thrombocytopenia, hypofibrinogenemia, and increased level of fibrinogen degradation product (FDP). After he had received blood component therapy including fresh frozen plasma and continuous intravenous heparin infusion (4,800 U/day), the bleeding diathesis and coagulopathy improved. He refused to have definitive surgery for the aneurysm.

The collision tumors have been reported in various organs and represent the coexistence of two adjacent but histologically distinct tumors in an organ without any histological admixture. A gastric collision tumor is rare and most gastric collision tumors involve an adenocarcinoma colliding with a lymphoma. A 48-year-old man was referred to our hospital for an evaluation of dyspepsia and upper abdominal discomfort. Endoscopy demonstrated the presence of an ulcerative lesion in the gastric antrum. The biopsy specimens confirmed a pathological diagnosis of an adenocarcinoma. After a radical subtotal gastrectomy, a thorough Histopathological examination revealed a collision tumor: a well-differentiated adenocarcinoma in the superficial layer (mucosa, submucosa) and a poorly differentiated neuroendocrine carcinoma in the deeper layer (muscularis propria, serosa). The patient received combination chemotherapy with cisplatin and etoposide. Para-aortic lymph node enlargement was observed on the abdominal computed tomography scanning, 3 years after surgery. The patient underwent chemotherapy with TS-1, and the size of lymph nodes was reduced. The patient continues to do well after a follow up period of 5 years 3 months. We report this case of gastric collision tumor (adenocarcinoma and neuroendocrine carcinoma) with a brief review of the relevant literature.

Hereditary hemorrhagic telangiectasia (HHT) is an autosomal dominant disorder that leads to mucocutaneous telangiectasias, epistaxis, and gastrointestinal bleeding. Depending on the severity and manifestation of the disease, various therapeutic modalities have been used, from local bleeding control to surgery or concomitant drug therapy. Several articles under review have presented guidelines for treatment of HHT with bevacizumab as a direct anti-angiogenesis strategy. Still, neither the exact optimal dose nor the minimum effective dose of intravenous bevacizumab in patients with severe HHT has been reported. A 55-year-old man presented with long-standing epistaxis, recent melena, dizziness, and a three-generation family history of chronic epistaxis, anemia, and regular blood transfusions. Treatment with argon plasma coagulation (APC) for the gastrointestinal bleeding failed to raise hemoglobin levels, we considered using the bevacizumab. We report a patient with severe HHT, who was treated with low-dose bevacizumab (2 mg/kg) and improved substantially.

Cerebrovascular disorders (infarction and intracranial hemorrhage), otherwise collectively referred to as stroke, are an uncommon and feared complication of pregnancy. Collectively, these disorders contribute up to 12% of all maternal deaths. Because of the common presentation with seizures, hypertension, proteinuria, and visual disturbance there has been diagnostic confusion with eclampsia, especially when cerebrovascular disorders occur antepartum or intrapartum. This case is intended to assist the clinician with clues for prompt diagnosis and therapy for this uncommon and unpreventable medical complication of pregnancy.
