PURPOSE: Transrectal needle biopsy of the prostate is a definitive diagnostic procedure for prostate cancer. However, the sensitivity of a third biopsy is very low in patients with serum prostate-specific antigen(PSA) 4-10 ng/ml and negative repeat prostate biopsy. In addition, multiple prostate biopsies usually have low patient compliance due to the pain and complications associated with the procedure. The aim of this study was to evaluate the role of transurethral resection of the prostate(TURP) for the diagnosis of prostate cancer in patients with lower urinary tract symptoms and clinical suspicion but with negative repeat biopsy samples. MATERIALS AND METHODS: From January 2000 to December 2006, 51 patients less than 80 years old underwent TURP at our institution for lower urinary tract symptoms with a serum PSA 4-10ng/ml and negative repeat transrectal needle biopsy of the prostate. We examined their first serum PSA, serum PSA before the TURP, PSA density, as well as their age, prostate size and digital rectal exam findings. The probability for the detection of prostate cancer by TURP was investigated retrospectively. RESULTS: Prostate cancer was detected in seven patients(13.7%). The total Gleason score for the biopsy specimens was 5 in two patients, 6 in one patient and 7 in four patients. There were significant differences between the prostate cancer group and the benign prostate hypertrophy group with regard to the PSA density and prostate volume. However there were no significant differences between the first serum PSA and the serum PSA before TURP in the two groups. CONCLUSIONS: In case with a high suspicion for prostate cancer, the TURP helps in the diagnosis of prostate cancer in those patients with a negative repeat biopsy and a serum PSA 4-10ng/ml and improvement of their lower urinary tract symptoms.

OBJECTIVES: A healthcare decision-making support model and rule management system is proposed based on a personalized rule-based intelligent concept, to effectively manage chronic diseases. METHODS: A Web service was built using a standard message transfer protocol for interoperability of personal health records among healthcare institutions. An intelligent decision service is provided that analyzes data using a service-oriented healthcare rule inference function and machine-learning platform; the rules are extensively compiled by physicians through a developmental user interface that enables knowledge base construction, modification, and integration. Further, screening results are visualized for the self-intuitive understanding of personal health status by patients. RESULTS: A recommendation message is output through the Web service by receiving patient information from the hospital information recording system and object attribute values as input factors. The proposed system can verify patient behavior by acting as an intellectualized backbone of chronic diseases management; further, it supports self-management and scheduling of screening. CONCLUSIONS: Chronic patients can continuously receive active recommendations related to their healthcare through the rule management system, and they can model the system by acting as decision makers in diseases management; secondary diseases can be prevented and health management can be performed by reference to patient-specific lifestyle guidelines.

OBJECTIVE: This study was conducted using the human papillomavirus (HPV) DNA chip test (HDC), in order to determine whether the HPV genotype is a predictor of residual disease in a subsequent hysterectomy following a loop electrosurgical excision procedure (LEEP) for cervical intraepithelial neoplasia (CIN) 3. METHODS: Between January 2002 and February 2015, a total of 189 patients who underwent a hysterectomy within 6 months of LEEP caused by CIN 3 were included in this study. We analyzed their epidemiological data, pathological parameters, high-risk HPV (HR-HPV) load as measured by the hybrid capture II assay, and HR-HPV genotype as measured by the HDC. A logistic regression model was used to analyze the relationship between covariates and the probability of residual disease in subsequent hysterectomy specimens. RESULTS: Of the 189 patients, 92 (48.7%) had residual disease in the hysterectomy specimen, CIN 2 in seven patients, CIN 3 in 79 patients, IA1 cancer in five patients, and IA2 cancer in one patient. Using multivariate analysis, the results were as follows: cone margin positivity (odds ratio [OR], 2.43; 95% CI, 1.18 to 5.29; p<0.05), HPV viral load > or =220 relative light unit (OR, 2.98; 95% CI, 1.38 to 6.43; p<0.01), positive endocervical cytology (OR, 8.97; 95% CI, 3.81 to 21.13; p<0.001), and HPV-16 or HPV-18 positivity (OR, 9.07; 95% CI, 3.86 to 21.30; p<0.001). CONCLUSION: The HPV-16 or HPV-18 genotype is a reliable predictive factor of residual disease in a subsequent hysterectomy following a LEEP for CIN 3.

BACKGROUND AND PURPOSE: Little is known about the relationships between provoking risk factors, prognosis, and optimal duration of anticoagulation in patients with cerebral venous thrombosis (CVT), especially in Asians. We aimed to investigate whether the prognosis and required duration of anticoagulation in CVT patients differ according to the provoking risk factors. METHODS: Prospectively recorded data from a tertiary medical center in South Korea were retrospectively reviewed. CVTs were categorized into three groups: unprovoked, those with possibly resolved provoking factors (PR), and those with persistent provoking factors (PP). The baseline characteristics, treatment, and prognosis of patients in these three groups were analyzed. RESULTS: From 2000 to 2015, 61 patients presented with CVT: 19 (31.1%) unprovoked, 11 (18.0%) with PR, and 31 (50.9%) with PP. The patients in our cohort had a slight female predominance and lower frequency of oral contraceptive use compared to Western cohorts. Median follow-up and duration of anticoagulation were 35 and 8 months, respectively. Despite the similarities in baseline characteristics, deaths (n=3; P=0.256) and recurrences (n=7; P=0.020) were observed only in the PP group. The median intervals to death and recurrence were 9 and 13 months, respectively. Death was associated with underlying disease activity, not with CVT progression. Recurrences in the PP group were associated with lack of anticoagulation (P=0.012). CONCLUSIONS: Although the prognosis of CVT is generally benign in Koreans, recurrence and death were observed in patients with persistent risk factors, suggesting their need for long-term treatment with anticoagulants.

BACKGROUND AND PURPOSE: The location of cerebral microbleeds (CMBs) may differ according to ischemic stroke subtype, and the underlying pathomechanism may differ by their location. Here, we investigated the characteristics of CMBs according to various ischemic stroke subtypes to verify this issue. METHODS: Patients with acute ischemic stroke were consecutively included. The presence of CMBs was determined by gradient echo image sequence. The distribution of CMBs was classified as deep, lobar, or diffuse (both deep and lobar). The prevalence, risk factors, and distribution of CMBs were compared among patients with different stroke subtypes. Factors associated with the distribution of CMBs were investigated. RESULTS: Among the 1033 patients included in this study, ischemic stroke subtypes were classified as large artery atherosclerosis (LAA; n=432), small vessel occlusion (SVO; n=304), and cardioembolism (CE; n=297). The prevalence of CMBs was highest in patients with SVO (40.5%), followed by CE (33.0%) and LAA (24.8%; P<0.001). The locations of CMBs was different according to subtype (P=0.004). CE [odds ratio (OR)=1.85 (1.02-3.34); P=0.042] and the use of antithrombotics [OR=1.80 (1.10-2.94); P=0.019] were associated with lobar CMBs, and old age [OR=1.02 (1.00-1.04); P=0.015] and hypertension [OR=1.61 (1.08-2.40); P=0.020] were associated with deep CMBs. CONCLUSIONS: CMBs were frequently located in the lobar area in patients with CE. Previous use of antithrombotic agents is associated with lobar CMBs. The pathogenic mechanism of CMB may differ according to ischemic stroke subtype and location.

BACKGROUND: Microbleeds (MBs), proposed as a biomarker for microangiopathy, have been suggested as a predictor of spontaneous or thrombolysis-related intracerebral hemorrhage (ICH) in acute ischemic stroke. However, the relationship between MBs and warfarin-induced ICH is not clear. CASE REPORT: We describe two patients who developed warfarin-induced ICH at the site of MBs documented in previous MRI. CONCLUSIONS: The presence of MBs might increase the risk of ICH after warfarin use in ischemic stroke patients. A large cohort study is required to confirm the relationship of MBs with warfarin-induced ICH.

BACKGROUND AND PURPOSE: Elucidating the factors that predict the quality of life (QOL) in stroke patients is important. However, the residual sensory symptoms that are common in stroke patients have not usually been included as factors that influence the QOL. The purpose of the present study was to elucidate the factors that predict the QOL of chronic-stage patients with special attention to residual sensory symptoms. METHODS: We examined 214 patients who had experienced a first-time stroke during the subacute (i.e., approximately 3 months poststroke) stage; 151 patients from this group were followed up by telephone interview during the chronic (i.e., approximately 3 years poststroke) stage. Physical disabilities, including motor dysfunction, sensory symptoms that included central poststroke pain (CPSP, described using a standardized questionnaire with a visual analogue scale), activities of daily living (ADL, measured by the Barthel index score), as well as the presence of depression (using the DSM IV criteria), were assessed during both the subacute and chronic stages. Economic and job statuses during the chronic stage were also assessed. QOL ratings were determined by the World Health Organization QOL scale. RESULTS: The following factors at 3 months poststroke were related to low QOL at 3 years poststroke: dependency in ADL, motor dysfunction, depression, and CPSP. At 3 years poststroke, dependency in ADL, depression, CPSP, poor economic status, and unemployment were all factors that were related to low QOL. Multiple regression analysis showed that dependency in ADL (19%), presence of CPSP (12%), and poor economic status (10%) were important explanatory factors for overall QOL. In the analysis of QOL subdomains, the most important explanatory factors were CPSP for both physical and psychological domains, dependency in ADL for both independence and social-relationships domains, economic status for the environmental domain, and female sex for the spiritual domain. CONCLUSIONS: We conclude that dependency in ADL, depression, low socioeconomic status, and the presence of CPSP either at 3 months or 3 years poststroke are factors that are related to a low QOL at 3 years poststroke. The recognition of these factors may allow strategies to be developed to improve the QOL for stroke patients.

Endometrial stromal sarcoma (ESS) is a rare malignancy. Development of extrauterine ESS form endometriosis is particularly rare. The majority of extrauterine ESS occurs in areas with preexisting endometriosis. The most common site is the ovary. We experienced a case of ESS of the ovary that arose from endometriosis with multiple disseminated lesions. This disease was managed by total abdominal hysterectomy, bilateral salpingo-oophorectomy, both pelvic lymph nodes dissection, omentectomy, and appendectomy followed by postoperative high-dose progesterone therapy. Here, we report this case with literature review.
