Evaluation of Appropriacy of Taking Water 2 Hour before Bioelectrical Impedance Analysis: Single-Frequency Bioelectrical Impedance Analysis Versus Multi-Frequency Bioelectrical Impedance Analysis

BACKGROUND: Bioelectrical impedance analysis (BIA) can be used to estimate body composition. To achieve the best results, the manufacturer's guidelines advise that individuals should restrict intake of food or caffeine, avoid vigorous exercise for 4 hours, and drink 2–4 glasses of water 2 hours before testing. We evaluated the appropriacy of drinking 2–4 glasses of water 2 hours before the BIA, as the validity of this indication has not been specifically demonstrated, by comparing intracellular water (ICW), extracellular water (ECW), total body water (TBW) in the fasting state, and after 1 and 2 hours of ingesting 500 mL of water.METHODS: Twenty-nine healthy adult men (n=10) and women (n=19) were recruited for the study. In the fasting state, the InBody 720 analyzer was used as multi-frequency (MF)-BIA and the output was recorded to determine the exact weight. Subsequently, Medinex BIA 450 analyzer was used as single-frequency (SF)-BIA, and the output was recorded. After drinking 500 mL of water 1 or 2 hours before assessment, the BIA tests were repeated as indicated above, and the ICW, ECW, TBW were compared by repeated measures ANOVA.RESULTS: SF-BIA measurements showed that compared to fasting state, the ICW decreased by approximately 0.56 L after 1 hour of drinking (P=0.001). The ECW was increased by about 0.62 L, 1 hour after drinking water compared to the fasting state (P=0.002). There were no significant differences between the results of BIA testing at 1 and 2 hours of fluid intake. The MF-BIA measurements indicated that testing after fasting, or 1 or 2 hours after fluid intake, did not result in significantly different ICW and ECW values. TBW showed no significant differences in the fasting state, or after 1 or 2 hours of fluid intake for both SF and MF.CONCLUSION: Several studies have shown that bioelectrical impedance should be measured in the fasting state. But not the food intake, drinking 500 mL of water may be permitted when measuring MF-BIA. However, for SF-BIA measurements, fluid intake resulted in an increase in the ECW level and a decrease in ICW.

Change in Palliative Performance Scale (PPS) Predicts Survival in Patients with Terminal Cancer / 한국호스피스완화의료학회지

PURPOSE: The Palliative Performance Scale (PPS) is a widely used prognostic tool in patients with advanced cancer. This study examines the association between changes in PPS score and survival in patients with advanced cancer. METHODS: We identified a cohort of 606 inpatients who died at a Korean university hospital's hospice/palliative care center. For each patient, the PPS score was measured twice according to a standard procedure: 1) upon admission, and 2) three days after admission (D3). “Change on D3” was defined as a difference between initial PPS and PPS on D3. We used a Cox regression modeling approach to explore the association between this score change and survival. RESULTS: The changes in scores were associated with survival. A score change of >30% yielded a hazard ratio for death of 2.66 (95% CI 2.19~3.22), compared to a score change of ≤30%. PPS of ≤30 on D3 also independently predicted survival, with a hazard ratio of 1.67 (95% CI 1.38~2.02) compared to PPS of >30. CONCLUSION: A change of over 30% in PPS appears to predict survival in hospitalized patients with terminal cancer, even after adjustment for confounders. Changes in PPS may be a more sensitive indicator of impending death than a single PPS measured on the day of admission in terminal cancer patients. Further prospective study is needed to examine this important finding in other populations.

Symptom Features of Terminally Ill Cancer Patients and Depression of Family Caregivers / 한국호스피스완화의료학회지

PURPOSE: There has been very little study on the associations between patient's symptoms themselves and family caregiver (FC)'s depression in the palliative phase. This cross-sectional study was to investigate the relationship between symptom features of terminally ill cancer patients and their FC's depression. METHODS: We performed a multicenter survey using the MD Anderson symptom inventory and the Hospital Anxiety and Depression Scale. A total of 293 patient-FC pairs were recruited from seven tertiary medical centers. A multivariate regression analysis was applied for identifying the relevant factors associated with FC depression and for estimating adjusted depression score of FCs. RESULTS: Among various psychosocial factors, low FC quality of life, low social support, spouse, and more caregiving time were significantly associated with FCs' depression. According to the presence of FCs' depression, there were significant differences in some symptom characteristics of patients. Even after adjusting for the relevant confounders, depression scores were lower in FCs caring for patients who had negative symptoms (loss of appetite, P=0.005; drowsiness, P=0.024; and dry mouth, P=0.043) than in FCs caring for patients who had not. FCs caring for patients with severe appetite loss had lower depression scores than those with not severe one (P=0.039). CONCLUSION: Our result suggests that patient's symptom characteristics might be helpful when evaluating a FC's depression.

Severe Complication of Percutaneous Dilatational Tracheostomy

Percutaneous dilatational tracheostomy (PDT) has become an increasingly popular method of establishing an airway for patients in need of chronic ventilator assistance. We report a rare case of a 42-year-old female who developed extensive subcutaneous emphysema, bilateral pneumothoraces, pneumomediastinum, and pneumoperitoneum after percutaneous dilatational tracheostomy. The patient suffered from amyotrophic lateral sclerosis, and underwent PDT after a period of mechanical ventilation. During PDT, tracheostomy tube was inserted into the paratracheal space. Follow-up chest radiography and computed tomography of chest and abdomen revealed extensive subcutaneous emphysema, bilateral pneumothoraces, pneumomediastinum, and pneumoperitoneum. The patient was treated successfully with insertion of the thoracostomy tube and conservative care.

Unmet Medical Service Needs in Family Caregivers of Terminal Cancer Patients / 한국호스피스완화의료학회지

PURPOSE: The unmet medical service needs of caregivers critically influence their caring for terminal cancer patients, but not much research has been done in this regard. Thus, the purpose of this study is to investigate the association between caregivers' characteristics and their unmet medical service needs. METHODS: The survey was conducted with 109 family caregivers of terminal cancer patients admitted to four hospice units. The data were collected from March 2014 through December 2014 using a structured questionnaire. The unmet medical service needs were measured using 14 items which were adopted and modified by authors. RESULTS: Seven areas of unmet medical service needs were shown to be significant. A well-educated group showed stronger needs for counsel about cancer screening and complementary-alternative medicine and health supplement food. A never-smoked group was identified with less need for sexual dysfunction counsel. Counsel about family and personal relations was more necessary for current drinkers and current workers, and less necessary for the married. Insurance counsel was more needed for a no-religion group. Occupation counsel was less necessary for healthy patients. Financial support was less necessary for the married group. CONCLUSION: Based on the results, it is highly recommended to further investigate the unmet medical service needs of family caregivers for terminal cancer patients and causes of the unmet needs.

Factors Associated with Care Burden among Family Caregivers of Terminally Ill Cancer Patients / 한국호스피스완화의료학회지

PURPOSE: It is important to alleviate care burden for terminal cancer patients and their families. This study investigated the factors associated with care burden among family caregivers (FCs) of terminally ill cancer patients. METHODS: We analyzed data from 289 FCs of terminal cancer patients who were admitted to palliative care units of seven medical centers in Korea. Care burden was assessed using the Korean version of Caregiver Reaction Assessment (CRA) scale which comprises five domains. A multivariate logistic regression model with stepwise variable selection was used to identify factors associated with care burden. RESULTS: Diverse associating factors were identified in each CRA domain. Emotional factors had broad influence on care burden. FCs with emotional distress were more likely to experience changes to their daily routine (adjusted odds ratio (aOR), 2.54; 95% confidence interval (CI), 1.29~5.02), lack of family support (aOR, 2.27; 95% CI, 1.04~4.97) and health issues (aOR, 5.44; 2.50~11.88). Family functionality clearly reflected a lack of support, and severe family dysfunction was linked to financial issues as well. FCs without religion or comorbid conditions felt more burdened. The caregiving duration and daily caregiving hours significantly predicted FCs' lifestyle changes and physical burden. FCs who were employed, had weak social support or could not visit frequently, had a low self-esteem. CONCLUSION: This study indicates that it is helpful to understand FCs' emotional status and family functions to assess their care burden. Thus, efforts are needed to lessen their financial burden through social support systems.

Delirium Management: Diagnosis, Assessment, and Treatment in Palliative Care / 한국호스피스완화의료학회지

Delirium is a common symptom in patients with terminal cancer. The prevalence increases in the dying phase. Delirium causes negative effects on quality of life for both patients and their families, and is associated with higher mortality. However, some studies reported that it tends to remain unrecognized in palliative care setting. That may be related with difficulties to distinguish the symptom from others with overlapping characteristics such as depression and dementia, and a lack of knowledge regarding assessment and diagnostic tools. We suggest that accurate recognition with validated tools and early diagnosis of the symptom should be highly prioritized in delirium management in palliative care setting. After diagnosing delirium, it is important to identify and address reversible precipitants such as medication, dehydration, and infection. Non-pharmacological interventions including comfortable environment for the patient and family education are also essential in the management strategy. If such interventions prove ineffective or insufficient to control hyperactive symptoms, pharmacologic interventions with antipsychotics and benzodiazepine can be considered. Until now, low levels of haloperidol remains the standard treatment despite a lack of evidence. Atypical antipsychotics such as olanzapine, quetiapine and risperidone reportedly have similar efficacy with a stronger sedating property and less adverse effect compared to haloperidol. Currently, delirium medications that can be used in palliative care setting require more clinical trials, and thus, clinical guidelines are not sufficiently available. We suggest that it is warranted to develop clinical guidelines based on well-designed clinical studies for palliative care patients.

Factors Affecting Research Participation of Bereaved Families of Terminal Cancer Patients: A Prospective Preliminary Study / 한국호스피스완화의료학회지

PURPOSE: Little is known regarding the factors associated with the willingness of family caregivers of terminal cancer patients to participate in a bereaved survey. This study aimed to ascertain the pre-loss factors that predict actual participation in a bereaved survey. METHODS: We conducted a prospective observational study using data from two multi-center surveys at the end-of-life and after loss. In order to identify the pre-loss factors associated with participating in the bereaved survey, we used a step-wise multivariate logistic regression analysis. RESULTS: Among 185 bereaved individuals, 30 responded to the survey (response rate: 16.2%). There were differences between the participation group and the non-participation group regarding religion, economic status, and perceived quality of care as assessed by the Quality Care Questionnaire-End of Life. A final multivariate model revealed that bereaved individuals who professed a religion (adjusted odds ratio [aOR]=5.01; P=0.008), had a high income (aOR=4.86, P=0.003), and satisfied with the care for familial relationship (aOR=4.49, P=0.003) were more likely to engage in the bereaved survey. CONCLUSION: Our finding suggests that improving the quality of end-of-life care may promote actual participation in a bereaved survey through easing post-loss distress. More attention should also be paid to those bereaved individuals who are hesitant to participate in a bereaved survey.

Factors Associated with Ketamine Use in Pancreatic Cancer Patient in a Single Hospice Center / 한국호스피스완화의료학회지

PURPOSE: Up to 90% of pancreatic cancer patients suffer from neuropathic pain. In a palliative care setting, pain control in pancreatic cancer patient is one of the major goals. Ketamine is a N-methyl-D-aspartate (NMDA) receptor antagonist, effective in neuropathic pain. Additionally, there have been studies about the opioid sparing effect of ketamine. This study was held in the palliative care unit among pancreatic cancer patients to determine the factors related to ketamine use and the opioid sparing effect. METHODS: The medical records of pancreatic cancer patients admitted to St. Mary's hospital palliative care unit between January, 2013 and December, 2014 were reviewed. Patients were divided into 2 categories according to ketamine use. Also, opioid use before and after ketamine use was compared in the ketamine group. RESULTS: Compared to the non-ketamine use group, patients in the ketamine group required a higher dose of opioid. The total opioid dose, daily opioid dose, number of daily rescue medications, and daily average rescue dose were statistically significantly higher in the ketamine group. The opioid requirement was increased after ketamine administration. CONCLUSION: In this retrospective study, ketamine was frequently considered in patients with severe pain, requiring higher amount of opioid. Studies about palliative use of ketamine in a larger number of patients with diverse types of cancer pain are required in the future.

The Korean guideline for hepatocellular carcinoma surveillance

Hepatocellular carcinoma (HCC) is one of the major cancers with a high incidence and mortality in Korea. A Korean multidisciplinary collaborative committee consisting of hepatologists, radiologists, epidemiologists and family medicine doctors systematically reviewed clinical practice guidelines in the world and literatures. The level of evidence for each recommendation was assessed and discussed to reach a consensus. Meta-analysis was also conducted to evaluate the grade of recommendation for the five key questions. Several randomized controlled studies and cohort studies showed a survival gain associated with surveillance for those at risk of developing HCC. The target populations for HCC surveillance were identified as hepatitis B virus or hepatitis C virus carriers and cirrhotic patients, since numerous studies revealed that these patients have significantly higher risk of HCC compared with non-infected or non-cirrhotic controls. Individual surveillance strategy according to treatment history or degree of fibrosis in patients with viral hepatitis remains to be settled. Based on several cohort and randomized studies, a surveillance interval of six months was recommend. The starting age of surveillance was determined as 40 years from the epidemiologic data. Although ultrasonography (US) is the mainstay for detection of HCC, its sensitivity is not fully accepted. Measurement of serum alpha-fetoprotein can complement US examination, increasing the sensitivity of HCC detection. The recommendation for HCC surveillance is that those with hepatitis B virus (or hepatitis C virus) infection or cirrhosis should have liver US and serum alpha-fetoprotein measurement every six months from 40 years of age or at the time of diagnosis of cirrhosis.

Is the Severity of Dilated Virchow-Robin Spaces Associated with Cognitive Dysfunction?

BACKGROUND AND PURPOSE: Dilated Virchow-Robin spaces (dVRS) are not uncommon findings in the normal brain, particularly in the old people, and have been largely regarded as benign lesions. However, there is accumulating evidence that dVRS may serve as an neuroimaging marker of small vessel disease and are associated with cognitive decline. We investigated whether the severity of dVRS would be associated with cognitive dysfunction by comparing the subjects with subjective memory impairment (SMI), mild cognitive impairment (MCI), and Alzheimer's disease (AD). We also examined whether there were differences in the degree of correlation between dVRS and magnetic resonance imaging (MRI) markers of small vessel disease among the three groups. METHODS: In this retrospective study, a total of 225 subjects were included: those with SMI (n=65), MCI (n=100), and AD (n=60). We rated the severity of dVRS using the axial MRI slice containing the greatest number of dVRS in the basal ganglia (dVRS-BG) and in the deep white matter (dVRS-WM), separately. We also assessed baseline characteristics including vascular risk factors and MRI markers of small vessel disease such as white matter hyperintensities (WMH), lacunar infarcts and microbleeds. RESULTS: A cumulative logit model revealed that the severity of cognitive dysfunction was associated with age (p<0.001), hypertension (p=0.006), diabetes mellitus (p=0.042), the severity of dVRS-BG (p=0.001), the severity of WMH (p=0.074) and the presence of lacunar infarcts (p<0.001) and microbleeds (p=0.003) in univariate analysis. However, after adjusting for other confounding variables, the severity of dVRS-BG was not a significant discriminating factor among subjects with SMI, MCI, and AD. Spearman's correlation analysis showed a trend that the correlation between the severity of dVRS-BG and the severity of WMH became more prominent in subjects with AD than in those with MCI or SMI (r=0.191 in SMI; r=0.284 in MCI; r=0.312 in AD), and the same is true of the severity of dVRS-BG and the number of lacunar infarcts. CONCLUSIONS: The severity of dVRS was associated with cognitive dysfunction, which appeared to be confounded by other well-known risk factors. The correlation between dVRS-BG and small vessel disease markers tended to be more significant with the advancement of cognitive impairment. These results suggest that severe dVRS may reflect cerebral small vessel disease and contribute to cognitive impairment.

A Case of Primary Papillary Thyroid Cancer That Caused Vocal Cord Palsy Arising from Thyroid Rest

Thyroid rest is isolated deposit of normal thyroid tissue arising in the thyrothymic tract below the lower pole of thyroid gland. Malignant transformation of thyroid rest is very rare. We report an extremely rare case of papillary carcinoma arising from thyroid rest in a 56-year-old male. He presented with hoarseness due to vocal cord palsy. Paratracheal mass in the upper mediastinum was identified by the cause of vocal cord palsy on CT. During surgery, we identified that the mass invaded recurrent laryngeal nerve but had no connection to thyroid gland. Histopathologic examination revealed that the mass was primary papillary thyroid carcinoma and there was no evidence of malignancy in thyroid gland. The post-therapeutic I-131 whole body scan detected several focal hot uptake in lung and mediastinum, suggesting distant metastasis. We should have knowledge of developmental variations of thyroid gland such as thyroid rest and its malignant transformation.

The Association between Phase Angle of Bioelectrical Impedance Analysis and Survival Time in Advanced Cancer Patients: Preliminary Study / 가정의학회지

BACKGROUND: A frequent manifestation of advanced cancer patients is malnutrition, which is correlated with poor prognosis and high mortality. Bioelectrical impedance analysis (BIA) is an easy-to-use and non-invasive technique to evaluate changes in body composition and nutritional status. We investigated BIA-derived phase angle as a prognostic indicator for survival in advanced cancer patients. METHODS: Twenty-eight patients treated at the hospice center of Seoul St. Mary's Hospital underwent BIA measurements from January, 2013 to May, 2013. We also evaluated palliative prognostic index (PPI) and palliative performance scale to compare with the prognostic value of phase angle. Cox's proportional hazard models were constructed to evaluate the prognostic effect of phase angle. The Kaplan Meier method was used to calculate survival. RESULTS: Using univariate Cox analysis, phase angle (hazard ratio [HR], 0.61/per degree increase; 95% confidence interval [CI], 0.42 to 0.89; P = 0.010), PPI (HR, 1.21; 95% CI, 1.00 to 1.47; P = 0.048) were found to be significantly associated with survival. Adjusting age, PPI, body mass index, phase angle significantly showed association with survival in multivariate analysis (HR, 0.64/per degree increase; 95% CI, 0.42 to 0.95; P = 0.028). Survival time of patients with phase angle > or = 4.4degrees was longer than patients with phase angle < 4.4degrees (log rank, 6.208; P-value = 0.013). CONCLUSION: Our data suggest BIA-derived phase angle may serve as an independent prognostic indicator in advanced cancer patients.

Association between Spiritual Well-Being and Pain, Anxiety and Depression in Terminal Cancer Patients: A Pilot Study / 한국호스피스완화의료학회지

PURPOSE: Spirituality is an important domain and is related with physical and psychological symptoms in terminal cancer patient. The aim of this study is to examine how patients' spirituality is associated with their physical and psychological symptoms as it has been explored by few studies. METHODS: In this cross sectional study, 50 patients in the palliative ward of a tertiary hospital were interviewed. Spiritual well-being, depression, anxiety and pain is measured by Functional Assessment of Chronic-Illness Therapy-Spirituality (FACIT-Sp), hospital anxiety and depression scale (HADS) and the Korean version of the Brief Pain Inventory (BPI-K). The correlations between patients' spiritual well-being and anxiety, depression and pain were analysed. The association between spiritual well-being and age, gender, palliative performance scale (PPS), religion, mean pain intensity, anxiety, depression were assessed by univariate and multivariate regression analyses. RESULTS: Spiritual well-being was negatively correlated with the mean pain intensity (r=-0.283, P<0.05), anxiety (r=-0.613, P<0.05) and depression (r=-0.526, P<0.05). In multivariate regression analysis, spiritual well-being showed negative association with anxiety (OR=-1.03, 95% CI=-1.657~-0.403, P=0.002) and positive association with the existence of religion (OR=9.193, 95% CI=4.158~14.229, P<0.001). CONCLUSION: In this study, patients' anxiety and existence of religion were significantly associated with spiritual well-being after adjusting age, gender, PPS, mean pain intensity, depression. Prospective studies are warranted.

Less Healthy Dietary Pattern is Associated with Smoking in Korean Men According to Nationally Representative Data

The relationship between smoking and nutrient intake has been widely investigated in several countries. However, Korea presents a population with a smoking rate of approximately 50% and dietary consumption of unique foods. Thus, the aim of this study was to evaluate the association of dietary patterns with smoking in Korean men using a nationally representative sample. The study subjects were comprised of 4,851 Korean men over 19 yr of age who participated in the fourth Korean National Health and Nutrition Examination Survey. Dietary data were assessed by the 24-hr recall method. The smoking group comprised 2,136 men (46.6%). Five dietary patterns were derived using factor analysis: 'sugar & fat', 'vegetables & seafood', 'meat & drinks', 'grains & eggs', and 'potatoes, fruits and dairy products.' Current smokers showed a more significant 'sugar & fat' pattern (P = 0.001) while significantly less of the 'vegetables & seafood' and 'potatoes, fruits and dairy products' patterns (P = 0.011, P < 0.001, respectively). As found in similar results from Western studies, Korean male smokers showed less healthy dietary patterns than nonsmokers. Thus, the result of this study underlines the need for health professionals to also provide advice on dietary patterns when counseling patients on smoking cessation.

Extent of resection for T2N0 gallbladder carcinoma regarding concurrent extrahepatic bile duct resection

BACKGROUNDS/AIMS: Gallbladder carcinoma (GBCa) T2 lesions are considered to be advanced tumors showing diverse features in tumor extent. When this T2 lesion does not involve the cystic duct and there is no evidence of lymph node metastasis, we have to consider what is the most reasonable extent of resection - that is, whether to perform concurrent extra-hepatic bile duct resection (EHBD) resection or not. This study intends to evaluate the adequacy of EHBD resection in patients undergoing resection for T2N0 GBCa. METHODS: From our institutional database of GBCa, 48 cases of T2N0 GBCa who underwent R0 resection during November 1995 and August 2008 were selected. Patients who underwent prior laparoscopic cholecystectomy were excluded. Their medical records were reviewed retrospectively. RESULTS: Their mean age was 63.2+/-83.3 years and females were 25. The mean serum CA19-9 level was 37.3+/-89.3 ng/ml. The extents of liver resection were wedge resection (n=36) and segment 4a+5 resection (n=12). Concurrent EHBD resection was performed in 16 (33.3%) patients. No fatal surgical complication occurred. The majority of tumor pathology was adenocarcinoma (n=42), with additional unusual types as papillary (n=3), saromatoid (n=1), signet ring cell (n=1) and adenosquamous (n=1) cancers. The overall survival rate was 87.1% at 1 year, 69.5% at 3 years and 61.7% at 5 years. After exclusion of mortalities not related to cancer, the overall patient survival rate was 89.6% at 1 year, 72.9% at 3 years and 64.7% at 5 years, with 3-year survival rates of 72% in the EHBD resection group and 69.2% in the non-resection group (p=0.661). CONCLUSIONS: The results of this study indicate that concurrent EHBD resection did not improve patient survival when R0 resection was achieved in patients with T2N0 GBCa. Therefore, routine EHBD resection may not be indicated for T2N0 GBCa unless the tumor is close to the cystic duct.

The Changes of Confidence, Accuracy and Knowledge of Medical Professionals after the Education for Survival Predictionin Terminally Ill Cancer Patients / 한국호스피스완화의료학회지

PURPOSE: In this study, we evaluated the effects of training for survival prediction of terminally ill patients in terms of medical professionals' confidence, accuracy and knowledge of survival prediction. METHODS: Twenty-nine participants completed a self-administered questionnaire where they scored their confidence, accuracy and knowledge of survival prediction before and after the training session. The training was provided in July 2009 at a university hospital located in Gyeonggi province, Republic of Korea. The participants were instructed by a professor of family medicine specialized in hospice palliative medicine to predict survival of a case using the palliative prognostic score and objective prognostic score. The training was provided in the form of a PowerPoint presentation for 40 minutes. RESULTS: Participants' confidence in survival prediction significantly increased from 4.00+/-1.73 (mean+/-SD) (0~10, visual analogue scale) to 5.83+/-1.71 after the training (P<0.001). Before training, participant's level of confidence significantly correlated with their age (P=0.04). The training significantly improved the correlation between the confidence level and the number of terminal cancer patients whom they have experienced (P=0.005 before training, P=0.017 after training). Participant's accuracy in survival prediction also significantly improved from 14 of 29 (48%) to 27 of 29 (93.1%) (P<0.001). The change in knowledge of survival prediction was too small to be statistically analyzed. CONCLUSION: After training, the confidence and accuracy scores significantly improved. Further study with a greater number of participants is needed to generalize this finding.

Clinicopathological features of the intraductal papillary neoplasms of the intrahepatic bile duct

BACKGROUNDS/AIMS: This study is intended to investigate the clinicopathological features of the intraductal papillary neoplasms of the intrahepatic bile duct (IPNB), especially focused on malignant changes. METHODS: From the institutional database of liver resection cases (Asan Medical Center, University of Ulsan College of Medicine), 18 patients who met the definition of IPNB were selected. They had undergone liver resection between February 2002 and October 2006; thus, the follow-up period was more than 5 years. RESULTS: Of the 18 patients, 11 patients were male. Their mean age was 61.3+/-6.7 years. There were no differences between the non-malignant and malignant lesions, in the comparison of the CEA levels (5.6+/-2.7 vs.12.6+/-31.1 ng/ml, p=0.439) and the CA19-9 levels (29.2+/-34.7 vs.31.9+/-30.2 ng/ml, p=0.871). The common radiologic findings were: intraductal growing mass in 10; bile duct dilatation in 6; and saccular duct dilatation in 2. Left and right hepatectomies were performed in 15 and 3, respectively. Five patients showed benign lesions of IPNB, and 13 patients revealed malignant lesions of intraductal papillary adnocarcinoma or cholangiocarcinoma. All 4 patients with benign lesions survived for a mean period of 53 months without recurrence. In 13 patients with the malignant lesions, 1-year, 3-year, and 5-year survival rates were 100%, 84.6%, and 59.2%, respectively. CONCLUSIONS: We concluded that intrahepatic IPNB is a rare type of biliary neoplasm which includes a histological spectrum, ranging from benign disease to invasive malignancy. The long-term survival was anticipated after complete curative resection.

Methanol Intoxication With Delayed Extensive Bilateral Subcortical Hemorrhage

The most characteristic radiological finding following methanol intoxication is bilateral necrosis of the putamina with varying degrees of hemorrhage. We report here on a 61-year-old Russian male with methanol intoxication who had delayed cerebral hemorrhage with a fatal course. The magnetic resonance image taken on admission revealed diffusion restriction lesions in the bilateral putamina, thalamus, and frontal and occipital subcortical white matter, without hemorrhage. Brain computed tomography performed on the 18th day revealed extensive bilateral hemorrhage in the multiple subcortical white matter, which led ultimately to death.

A clinical study of child bacterial meningitis in Daejeon and Chungcheong area : 2001-2005 / 소아과

PURPOSE: The purpose of this study was to analyze the epidemiology, causative organism, clinical manifestation and prognosis of bacterial meningitis for children after the introduction of Haemophilus influenzae type b (Hib) vaccine in Daejeon and Chungcheong area. METHODS: We analyzed retrospectively 53 medical records who had been diagnosed with bacterial meningitis at 10 general or university hospitals in Daejeon and Chungcheong area. All patients aged 1 month-14 years admitted between January 2001 through December 2005. RESULTS: During the 5-year study period, 40 of all cases were positive for bacterial growth. Of the 40 cases that were CSF culture-proven bacterial meningitis, Streptococcus peumoniae was the most common bacteria for 17 (32.1%) of all cases, followed by H. influenzae for 10 (18.9%), Neisseria meningitidis for 3 (5.7%). In this study, the most common clinical manifestation is fever, accompanied by all cases. CSF leukocyte count was more than 100/mm3 in 45 (84.1%) cases. CSF glucose concentration was less than 50 mg/dL in 42 (79.2%) cases and protein concentration was more than 45 mg/ dL in 49 (92.5%) cases. 45 of all cases made a recovery after treatment and were discharged. Most common complication after treatment is subdural effusion (19.0%) and hearing disturbance (9.4%). CONCLUSION: The most common organism of culture-proven bacterial meningitis in the children beyond neonatal period was S. pneumoniae. Continued surveillance studies were demanded to know the altered incidence of bacterial meningitis, because we expect the incidence of S. pneumoniae meninigitis will be on the decrease after more active innoculation of pneumococcal protein conjugate vaccine.
