RESUMO
RATIONALE: Computed tomography plays a key role in the initial evaluation of suspected acute stroke by ruling out the possibility of hemorrhage before thrombolysis. Recently, many reports have described cases of symptomatic microbleeds, and there may also have been a case of computed tomography- negative intracerebral hemorrhage. PATIENT CONCERNS: A 70-year-old female patient who had a history of lacunar infarction and severe small vessel disease developed dysarthria. On brain non-contrast computed tomography there was no evidence of intracerebral hemorrhage. However, brain magnetic resonance imaging performed at 3âhours after the initial computed tomography showed cerebral hemorrhage. DIAGNOSES: The diagnosis was computed tomography-negative intracerebral hemorrhage. INTERVENTIONS: The patient was treated with cilostazole 100âmg twice a day with blood pressure management. OUTCOMES: The dysarthria was fully recovered within 5 days and the patient did not suffer recurrent stroke symptoms over the following 2 years. LESSONS: In patients with underlying severe small vessel disease and microbleeds, there could be computed tomography-negative hemorrhage and susceptibility weighted magnetic resonance image could be needed. More attention is required before applying thrombolysis therapy because there is a possibility of cerebral hemorrhage in those patients.

RATIONALE: Tolosa-Hunt syndrome (THS) is rare condition characterized by painful ophthalmoplegia that usually responds well to corticosteroid. About a half of THS patients experience recurrence within intervals of months to years from initial presentation. Recurrence is more common in younger patients, and can be ipsilateral, contralateral, or bilateral. Cyclosporine, azathioprine, methotrexate, mycophenolate mofetil, infliximab, and radiotherapy can be considered as second-line treatment. However, there is insufficient evidence for treatments preventing recurrence of THS. PATIENT CONCERNS: We experienced two patients with THS that recurred twice while tapering or after ceasing corticosteroid administration. DIAGNOSIS: Both patients were diagnosed as recurrent THS. INTERVENTIONS: Methotrexate was treated with a combination of corticosteroid after THS recurred twice with corticosteroid therapy alone. OUTCOMES: After adding methotrexate to the steroid regimen, their symptoms were successfully regulated and ceased to recur LESSONS:: These cases add to the evidence for the use of methotrexate as a second-line therapeutic agent for those patients with recurrent THS attacks. Further studies are in need to prove the risk and benefits of second-line treatments in THS.

BACKGROUND AND PURPOSE: Disability associated with activities of daily living (ADL) is the basis of dementia diagnosis and is an important factor in the care of dementia patients. The status of awareness and burden of ADL disability in dementia patients was investigated six years ago and used as an important reference for "Il-sang-ye-chan" campaign. They were re-investigated in six years and compared with previous results. METHODS: The survey included caregivers of 100 dementia patients listed at the four regional dementia centers. Structured open and closed questions about ADL were asked. Assessments included age, sex, education level, economic status, severity of dementia, caregiving pattern, current statues and cognition of ADL, and caregiver needs. RESULTS: The cognition of ADL was still very low (43%). Increased stress among caregivers was the biggest burden, and they frequently suffered from outing disability (56%), recent memory loss (48%), and loss of bowel/bladder control (40%). The economic burden has been greatly reduced compared with the burden six years ago and the needs of caregivers were still highly about educational guide lines or programs. CONCLUSIONS: Continued interest and further investigation into ADL disability of dementia patients are needed. Korean Dementia Association will further expand the "Il-sang-ye-chan" program: via a multi-domain cognitive intervention program under the Care for ADL in dementia and Relieve symptoms in Dementia Project.
RESUMO
Severe fever with thrombocytopenia syndrome (SFTS) is a tick-borne viral disease with a high mortality rate. Infection can also occur through close contact with an infected patient. Scrub typhus is an acute febrile illness caused by Orientia tsutsugamushi, a bacterium transmitted to humans through chigger mite bites. South Korea is an endemic region of SFTS and scrub typhus. In this study, we confirmed that a patient was coinfected with SFTS virus and two (Boryong and Taguchi) genotypes of O. tsutsugamushi.

BACKGROUND: Decline in neurocognitive function is a reported complication in children with chronic illness. Concerns have been increasing that exposure to a major surgery or trauma may negatively affect cognitive performance in children. This study evaluated cognitive function in 43 Korean children who received organ transplantation (Tx), and sought to identify associated clinical factors. METHODS: Pediatric recipients of kidney (KT) or liver Tx (LT) from 1999 to 2011 were recruited for cognitive tests. Cognitive function was evaluated using intelligence quotient (IQ), social quotient (SQ), and Continuous Performance Test using Advanced Test for Attention scores, which reflect attention ability. Intellectual delay was graded as intellectual disability (ID; IQ <70) or low intelligence (LI; IQ<85). Diagnosis for attention-deficit-hyperactivity disorder (ADHD) was made by pediatric psychiatrists. RESULTS: The subjects consisted of 43 pediatric recipients of 28 LT and 15 KT. There were 20 boys (46.5%). Median age was 3.1 years (range, 0.5-15.3 years) at Tx. Median age at cognitive evaluation was 12.9 years (range, 3.4-18.4 years). Median pre-Tx duration of illness was 1.6 years (range, 0-13.5 years). The prevalence of ID, LI, and ADHD was 11.6%, 32.5%, and 32.5%, respectively. On multivariate analysis, longer pre-Tx duration of illness was a significant factor for LI (OR, 1.263; 95%CI: 1.033-1.544, P = 0.023). CONCLUSION: Longer pre-Tx duration may negatively affect intellectual ability in Korean children. Pre-Tx duration was more significant than the age at Tx or total disease duration per se. Early Tx may be beneficial for cognitive function in children.

OBJECTIVE: We aimed to examine the rates, correlates, methods, and precipitating factors of suicide attempts among adolescent patients admitted for psychiatric inpatient care from 1999 to 2010 in a university hospital in Korea. METHODS: The subjects consisted of 728 patients who were admitted for psychiatric inpatient care in a university hospital over a 12-year period and who were aged 10-19 years at the time of admission. We retrospectively investigated the information on suicidal behaviors and other clinical information by reviewing the subjects' electronic medical records. Whether these patients had completed their suicide on 31 December 2010 was determined by a link to the database of the National Statistical Office. RESULTS: Among 728 subjects, 21.7% had suicidal ideation at admission, and 10.7% admitted for suicidal attempts. Female gender, divorced/widowed parents, and the presence of mood disorders were associated with a significantly increased likelihood of suicide attempts. Most common method of suicide attempts was cutting, and most common reason for suicide attempts was relationship problems within the primary support group. A diagnosis of schizophrenia was associated with increased risk of death by suicide after discharge. CONCLUSION: These results highlight the role of specific psychosocial factor (e.g., relational problems) and psychiatric disorders (e.g., mood disorders) in the suicide attempts of Korean adolescents, and the need for effective prevention strategies for adolescents at risk for suicide.
RESUMO
Human papillomavirus (HPV) 58 accounts for a notable proportion of cervical cancers in East Asia and parts of Latin America, but it is uncommon elsewhere. The reason for such ethnogeographical predilection is unknown. In our study, nucleotide sequences of E6 and E7 genes of 401 HPV58 isolates collected from 15 countries/cities across four continents were examined. Phylogenetic relationship, geographical distribution and risk association of nucleotide sequence variations were analyzed. We found that the E6 genes of HPV58 variants were more conserved than E7. Thus, E6 is a more appropriate target for type-specific detection, whereas E7 is more appropriate for strain differentiation. The frequency of sequence variation varied geographically. Africa had significantly more isolates with E6-367A (D86E) but significantly less isolates with E6-203G, -245G, -367C (prototype-like) than other regions (p ≤ 0.003). E7-632T, -760A (T20I, G63S) was more frequently found in Asia, and E7-793G (T74A) was more frequent in Africa (p < 0.001). Variants with T20I and G63S substitutions at E7 conferred a significantly higher risk for cervical intraepithelial neoplasia grade III and invasive cervical cancer compared to other HPV58 variants (odds ratio = 4.44, p = 0.007). In conclusion, T20I and/or G63S substitution(s) at E7 of HPV58 is/are associated with a higher risk for cervical neoplasia. These substitutions are more commonly found in Asia and the Americas, which may account for the higher disease attribution of HPV58 in these areas.

AIM: This cross-sectional, hospital-based study examined the distribution of human papillomavirus 16 E6 and E7 gene variants in Korean women with cervical lesions of varying degrees. MATERIAL & METHODS: One hundred and forty-one Korean women (median age 43 years; range 22-65 years) with human papillomavirus 16 single infections were included. The human papillomavirus 16 E6/E7 sequences were amplified from cytology specimens. The distribution of human papillomavirus 16 variations with respect to cervical lesion was examined by the exact Mantel-Haenszel linear trend test (P(trend) ) and Fisher's exact test (P). RESULTS: Human papillomavirus 16 E6 and E7 gene variants were identified in a total of 100 women (70.9%). The most prevalent human papillomavirus 16 variants were E6 Thymine178Guanine (number = 70, 49.6%) and E7 Adenine647Guanine (number = 75, 53.2%). Human papillomavirus 16 E6 Thymine178Guanine and E7 Adenine647Guanine were significantly related to the degree of cervical neoplasia (P(trend) = 0.0002, P< 0.0001; P(trend) < 0.0001, P < 0.0001, respectively). The odds ratio of human papillomavirus 16 E6 Thymine178Guanine to predict progression to cervical intraepithelial neoplasia 2-3 and invasive cancer was 2.37 (95% confidence interval 1.03-5.45) and 9.07 (95% confidence interval 2.86-28.72), respectively. The odds ratio of E7 Adenine647Guanine to predict progression to cervical intraepithelial neoplasia 2-3 and invasive cancer was 3.65 (95% confidence interval 1.16-8.51) and 9.07 (95% confidence interval 2.86-28.72), respectively. CONCLUSION: The distribution of HPV variants appears to be related to geographic difference. Human papillomavirus 16 E6 Thymine178Guanine and E7 Adenine647Guanine can be used as the candidate marker for the progression of the cervical neoplasia.

BACKGROUND: Human papillomavirus type 58 (HPV-58) accounts for a much higher proportion of cervical cancers in East Asia than other types. A classification system of HPV-58, which is essential for molecular epidemiological study, is lacking. METHODS AND RESULTS: This study analyzed the sequences of 401 isolates collected from 15 countries and cities. The 268 unique concatenated E6-E7-E2-E5-L1-LCR sequences that comprised 57% of the whole HPV-58 genome showed 4 distinct clusters. L1 and LCR produced tree topologies that best resembled the concatenated sequences and thus are the most appropriate surrogate regions for lineage classification. Moreover, short fragments from L1 (nucleotides 6014-6539) and LCR (nucleotides 7257-7429 and 7540-52) were found to contain sequence signatures informative for lineage identification. Lineage A was the most prevalent lineage across all regions. Lineage C was more frequent in Africa than elsewhere, whereas lineage D was more prevalent in Africa than in Asia. Among lineage A variants, sublineage A2 dominated in Africa, the Americas, and Europe, but not in Asia. Sublineage A1, which represents the prototype that originated from a patient with cancer, was rare worldwide except in Asia. CONCLUSIONS: HPV-58 can be classified into 4 lineages that show some degree of ethnogeographic predilection in distribution. The evolutionary, epidemiological, and pathological characteristics of these lineages warrant further study.

AIM: The aim of this study was to evaluate the behavior of low-grade squamous intraepithelial lesion (LSIL) in Korean women infected with human papillomavirus (HPV) in relation to the immunocytochemical detection of the HPV L1 capsid protein. MATERIAL AND METHODS: From January 2006 to December 2007, a total of 353 immunocytochemistry tests were performed on specimens from HPV-infected patients with LSIL. Due to exclusions, the study population was reduced to 318. Subjects were monitored at 4-6 month intervals. The regression, persistence, and progression of the cytologic abnormalities of the 318 cases were compared with the results of HPV L1 capsid protein immunocytochemical detection. RESULTS: Of the 137 patients negative for the HPV L1 capsid protein, 38 (27.7%) showed progression to high-grade lesions, 50 (36.5%) showed persistence, and 49 (35.8%) showed regression to normal cytological features. In contrast, of the remaining 181 patients positive for the HPV L1 capsid protein, 15 (8.3%) showed progression to high-grade lesions, 74 (40.9%) showed persistence, and 92 (50.8%) showed regression. The results of immunocytochemical testing for the HPV L1 capsid protein show a linear association with the progression or regression behavior of low-grade cervical cytology in patients infected with HPV (linear by linear association test, P<0.05). CONCLUSION: Immunocytochemical detection of HPV L1 was significantly related with the biological patterns of LSIL in Korean women. Hence, immunocytochemistry for the detection of HPV L1 is beneficial in providing further information for LSIL.

AIMS: The aim of this study was to review the clinical manifestations of pelvic actinomycosis in order to aid clinicians in its diagnosis and treatment. METHODS: We retrospectively reviewed the histopathology and clinical records of all cases confirmed by surgery as pelvic actinomycosis from 1996 to 2006. RESULTS: A total of 16 cases of pelvic actinomycosis were selected and evaluated. The median age was 51 years (range, 36-66 years). All patients experienced childbirth, and had risk factors including use of an intrauterine device (93.8%) or pessary (6.2%), and/or a history of dilatation and curettage (68.8%), or previous abdominal surgery (31.3%). Nine patients (56.3%) were correctly diagnosed before surgery with computed tomography. Other common preoperative diagnoses were intra-abdominal malignancy (18.8%) and tubo-ovarian abscess (25%). The most common initial laboratory abnormalities were anemia (68.8%) and leukocytosis (62.5%). In six patients (37.5%), the preoperative values of carbohydrate antigen-125 were elevated. All patients were cured by surgery and no recurrence or mortality was noted. CONCLUSIONS: The correct initial diagnosis of pelvic actinomycosis is important for decreasing treatment-related morbidity. Imaging studies, especially computed tomography, might have assisted the diagnoses of actinomycosis.

For intraoperative consultation of mucinous adenocarcinoma involving the ovary, it would be useful to have approaching methods in addition to the traditional limited microscopic findings in order to determine the nature of the tumors. Mucinous adenocarcinomas involving the ovaries were evaluated in 91 cases of metastatic mucinous adenocarcinomas and 19 cases of primary mucinous adenocarcinomas using both an original algorithm (unilateral >or=10 cm tumors were considered primary and unilateral <10 cm tumors or bilateral tumors were considered metastatic) and a modified cut-off size algorithm. With 10 cm, 13 cm, and 15 cm size cut-offs, the algorithm correctly classified primary and metastatic tumors in 82.7%, 87.3%, and 89.1% of cases and in 80.6%, 84.9%, and 87.1% of signet ring cell carcinoma (SRC) excluded cases. In total cases and SRC excluded cases, 98.0% and 97.2% of bilateral tumors were metastatic and 100% and 100% of unilateral tumors <10 cm were metastatic, respectively. In total cases and SRC excluded cases, 68.4% and 68.4% of unilateral tumors >or=15 cm were primary, respectively. The diagnostic algorithm using size and laterality, in addition to clinical history, preoperative image findings, and operative findings, is a useful adjunct tool for differentiation of metastatic mucinous adenocarcinomas from primary mucinous adenocarcinomas of the ovary.

Müllerian adenosarcoma is a rare biphasic tumor in young women. These tumors can recur even after complete resection. We present a patient treated with oral progesterone after hysterectomy with ovary conservation. A 35-year-old woman had a diagnosis of adenosarcoma on hysteroscopic resection, which was estrogen and progesterone receptor positive. She underwent total hysterectomy with ovary conservation and has received oral medroxyprogesterone acetate treatment. At 15 months after surgery, there has been no disease recurrence. Oral medroxyprogesterone acetate therapy can be used effectively in young women with müllerian adenosarcoma whose ovaries are preserved.

OBJECTIVE: Colorectal adenocarcinoma, the most common tumor that metastasizes to the ovary, is often difficult to distinguish from primary ovarian mucinous adenocarcinoma (POMA). Obtaining the correct diagnosis is difficult but crucial to treatment and prognosis. METHODS: We evaluated the immunohistochemical (IHC) expression of cytokeratin 7 (CK7), cytokeratin 20 (CK20), CDX2, CEA, MUC2, MUC5AC and alpha-methylacyl-CoA racemase (AMACR) in 22 POMAs and 41 metastatic colorectal adenocarcinomas (MCAOs) involving ovaries. RESULTS: MCAOs, in contrast with POMAs, were almost always negative for MUC5 (97.6%), often negative for CK7 (82.9%), focal or diffuse positive for CDX2 (73.2%), diffuse positive for CK20 (65.9%), focal or diffuse positive for MUC2 (51.2%), diffuse positive for CEA (41.5%) and negative for AMACR (41.5%). We therefore considered CK7 (-), CK20 (diffuse +), CDX2 (+) and MUC2 (+) to be colonic markers and regarded cases with expression of more than two colonic markers as MCAO, those with no expression of colonic markers as POMA and those with expression of one colonic marker as indeterminate. Using CK7/CK20/CDX2/MUC2, 82.5% of the cases were correctly classified, 6.3% were misclassified and 6.3% were indeterminate. CONCLUSION: CK7, CK20, CDX2 and MUC2 IHC staining is a useful adjunctive diagnostic tool to differentiate MCAOs from POMAs, in addition to clinical history and gross and microscopic findings.

This cross-sectional study examined the distribution of HPV 58 sequence variation in Korean women for the first time. Among 1,750 Korean women, 53 women were positive for HPV 58 single infection, of whom 26 were without disease, 20 were with cervical intraepithelial neoplasia (CIN) 1, and 7 with CIN 2 or 3. Altogether, 36 different nucleotide sequence variations were identified with the L1, 20 within E2, 5 within E6, and 10 within E7. Further studies on variants of oncogenic HPVs are necessary, particularly for the purpose of developing more predictive HPV detection methods.

Approximately 5-30% of the ovarian cancers are metastatic malignancies. The prevalence of metastatic ovarian tumors varies with the incidence rates and spread patterns of primary malignancies. We evaluated the prevalence, pre- and postoperative characteristics of metastatic ovarian cancer in Korean women. We reviewed the records for 821 ovarian malignancies with pathological consultation from 1996-2006 and recorded patient demographical, radiological, histopathological, and survival data. The study included 112 cases of histologically confirmed metastatic ovarian cancer. Metastatic ovarian cancer accounted for 13.6% of all ovarian malignancy, primarily arising from the gastrointestinal tract. The preoperative detection rate with imaging was 75%, and none of the radiological or serological features were useful for differential diagnosis. In multivariate analysis for prognostic variables, the only significant factor was the primary tumor site (p=0.004). Furthermore, extensive resection increased survival for some patients. The differential diagnosis of metastatic ovarian cancer can be problematic, so multiple diagnostic approaches are necessary. The extent of cytoreductive surgery for this type of tumor must be decided on a case-by-case basis.

Previously, we used proteome analysis to identify transforming acidic coiled coil (TACC) 3 as a protein that is down-regulated upon paclitaxel treatment in cervical cancer cells. TACC3 mRNA and protein levels decreased after paclitaxel treatment in a time- and dose-dependent manner, and the transactivation of TACC3 promoter was dramatically diminished by paclitaxel. Importantly, paclitaxel treatment and knockdown of TACC3 by siRNA led to a synergistic enhancement of significant G2/M phase arrest and apoptosis in HeLa cells. In contrast to TACC3-deficient cells, paclitaxel treatment of mTACC3-overexpressing cells failed to induce G2/M phase arrest, cell growth inhibition, and apoptotic cell death. We studied the associated gene in mTACC overexpressed cells using microarray. From these results, numerous genes have been identified as being associated with tumor progression (Ppia, TMSB10, Annexin A2, rab31, prostaglandin E2-EP2, UHRF1), chemoresistance (Akt, Plk-1, MAP kinase) and metastasis (MMP9, PECAM-1) in mTACC3 overexpressed HeLa cells. Thus, TACC3 is thought to be the critical molecule in mediating the anticancer mechanisms of paclitaxel in p53 inactivated cells by inducing G2/M arrest and apoptosis. And our data suggested that the overexpression of TACC3 may be associated with the mechanisms of chemoresistance, tumor progression, cell proliferation and metastasis.

OBJECTIVES: We aimed to determine the efficacy and feasibility of neoadjuvant chemotherapy (NACT) using cisplatin and etoposide in patients with locally advanced cervical cancer. METHODS: Previously untreated patients with histologically confirmed stage 1B-2B cervical cancer were treated with three courses of NACT (60 mg/m2 cisplatin on days 1 and 2 plus 100 mg/m2 etoposide on day 1) every 10 days. NACT was followed within 2-3 weeks by radical hysterectomy with lymph node dissection. RESULTS: From 1999 to 2004, 112 patients were enrolled and 99 patients were evaluable. All eligible patients had radical surgery after NACT. Hematologic toxicity was the most common side effect, and the level of toxicity was acceptable. The overall pathologic response rate was 69.7% (69/99). The median follow-up period was 49 months, and the 5-year overall and progression-free survival rates were 88.1% and 60.5%, respectively. CONCLUSION: NACT with cisplatin and etoposide for patients with locally advanced cervical cancer is promising and has an acceptable toxicity profile. The regimen timing (every 10 days) did not delay the optimal time for radical treatment.

The aim of the present study is to estimate the overall prevalence and type distribution of human papillomavirus (HPV) in Korean women, through literature review and meta-analysis. We searched published data for the period between 1995 and 2007 using the following inclusion criteria; (1) studies using type-specific HPV tests, (2) data from Korean female, (3) with cytologic or pathologic results, (4) having more than 20 cases for each subgroup classified by cytologic results, and (5) HPV detection including types 16, 18, and at least one other type. In total, 18 studies (13,842 cases) published up to April 2007 were identified and selected. Adjusted overall HPV prevalence was 23.9% (95% CI: 23.8-24.1%) in women with normal cytology and 95.8% (95% CI: 95.4-96.2%) in women with cervical cancer. Type 16 was predominant regardless of cervical disease status, and type 58 occupied a significantly larger proportion in high-grade cervical intraepithelial lesions and cervical cancer in Korean women. HPV types 58, 33, and 52 together accounted for about 20% of infections in cervical cancer and high-grade intraepithelial lesions. After introduction of HPV prophylactic vaccines, extended protection, especially against types 58, 33, and 52, will be an important issue for cervical cancer prevention in Korea. The future dominant genotypes will require follow-up epidemiological studies with a large-scale, multicentered, and prospective design.

OBJECTIVE: We assessed the prognostic factors and the efficacy of adjuvant therapy and reviewed randomized studies carried out on patients receiving adjuvant therapy with early endometrial carcinoma. METHODS: One hundred and five patients that received primary surgical treatment for stage IB, IC and II endometrial cancer were enrolled in this study. The clinical outcomes were compared among the patients with variable prognostic factors and adjuvant treatments. RESULTS: One hundred and five patients fulfilled the eligibility criteria and 46 patients (43.8%) underwent adjuvant therapy. Disease recurrence occurred in nine patients within a median time of 24 months. Cervical involvement was an independent prognostic factor for the disease-free survival rates. Eight of 16 patients with FIGO stage II disease received adjuvant chemotherapy consisting of cisplatin and etoposide (or cyclophosphamide) or combined chemoradiation. The 5-year disease-free survival rate for these patients was 87.5%, a value significantly higher than for patients that received radiation therapy alone (30%). CONCLUSION: Adjuvant chemotherapy or combination chemo-radiotherapy might be superior to radiation therapy alone in high-risk early endometrial cancer patients.
