OBJECTIVETo evaluate pericardial endothelin (ET) secretion by the human pericardial mesothelial cells.
METHODSPlasma, pericardial fluid and pericardial tissue were obtained in 51 patients receiving open heart surgery (coronary artery bypass grafting, elective heart valvuloplasty or valve replacement). ET concentrations in the plasma, pericardial fluid and pericardial tissues were measured by radioimmunoassay (RIA). ET mRNA expression in the human pericardium was detected by in situ hybridization.
RESULTS(1) The levels of ET in human pericardial fluid was significantly higher than that in the plasma [(128.8 +/- 44.0) ng/L vs. (93.7 +/- 28.6) ng/L, P < 0.001]; (2) ET concentration in the pericardial tissue was (510.3 +/- 156.7) ng/kg; (3) In situ hybridization technique evidenced the abundant ET mRNA expression in human pericardial mesothelial cells.
CONCLUSIONThe study indicated that pericardium secreted ET into the pericardial space.

Primary or isolated chylopericardium of unknown etiology is considered a rare cause of pericardial effusion. Its etiology is obscure but certain communication between the lymphatic system and pericardial sac was suggested. Up to 1991, there was only one case report that successfully showed the direct communication by a lymphangiogram. We report a case of chylopericardium occurring in a nearly asymptomatic 22-year-old man with no apparent history of trauma, infection or mediastinal neoplasm, in which we succeeded in visualizing the communication between the thoracic duct and pericardial sac by lymphangiography and computed tomography of the chest. A review of the previous cases is described also.

OBJECTIVETo determine the diagnostic value of B72.3, BerEP4 and calretinin in differentiating metastatic carcinoma cells from reactive mesothelial cells (RMC) in serous effusions by using immunocytochemical method (ICC), and to investigate the feasibility of ThinPrep (TP) preparation for ICC.
METHODSOne hundred fifty eight serous effusion specimens were examined by ICC on cell block (CB) sections (CB-ICC) using antibodies against of B72.3, BerEP4 and calretinin. Fourty-nine of the samples, ICC on ThinPrep slides (TP-ICC) and CB-ICC were performed concurrently.
RESULTSThe sensitivities of B72.3 and Ber-EP4 for detecting carcimoma cells were 76.9% and 69.2% respectively, and when combined the sensitivity was increased to 89.7%. The sensitivity and specificity of Calretinin for detecting mesothelial cells were 90.9% and 87.2% respectively. The sensitivity of B72.3 in differentiating cancer cells from reactive mesothelial cells by CB-ICC and TP-ICC was 78.9% and 68.4%. It was 78.9% and 68.4% of BerEP4 respectively. No statistical significance was observed between CB-ICC and TP-ICC in differentiating metastatic carcinoma cells from reactive mesothelial cells.
CONCLUSIONThe combination of antibodies of B72.3, Ber-EP4 and calretinin is quite helpful as an auxiliary in differentiating metastatic carcinoma cells from reactive mesothelial cells. ThinPrep preparation slides may effectively replace the cell block sections for ICC in differential diagnosis of serous effusions.

This study was designed to examine the relationship between pericardial fluid and plasma CRP levels, and to alterations in other biochemical parameters in patients undergoing Coronary Artery Bypass Grafting (CABG). The study group consisted of 96 Coronary Artery Disease (CAD) patients who were referred to our clinic for a CABG procedure and from whom sufficient amount of pericardial fluid could be collected. The patients were classified into 3 groups: Stable Angina Pectoris (SAP) (n=27), Unstable Angina Pectoris (USAP) (n=36), and Post-Myocardial Infarction (PMI) (n=33). Levels of CRP, glucose, albumin, total protein, Creatine Kinase (CK), Creatine Kinase-MB (CK-MB), and Lactate Dehydrogenase (LDH) were determined in pericardial fluid samples and in simultaneously collected blood samples from radial artery. The pericardial CRP and LDH levels in the PMI group were higher than in the SAP (p=0.015 and p=0.000, respectively) and USAP (p=0.011, p=0.047) groups. Serum CRP levels in USAP (p=0.014) and PMI (p= 0.000) groups were higher than those in the SAP group. Pericardial albumin levels in the PMI group were higher than in the USAP group (p=0.038). In all groups, the pericardial fluid/serum protein ratio was > 0.5, the LDL ratio was > 0.6, and pericardial fluid LDH concentrations were > 300mg/dl. CRP level of pericardial fluid was significantly higher in the PMI group than in other groups. However, pericardial fluid LDH levels were higher than blood LDH levels in this group and were also higher than pericardial fluid LDH levels of other groups.

OBJECTIVEThe aim of this study was to examine the levels of prostaglandin E2 in periapical exudates before and after root canal treatment.
METHODSPeriapical exudates specimens were quantitatively sampled from root canals of 25 teeth at consecutive treatment visits, and the concentration of prostaglandin E2 in each sample was determined using a commercial kit.
RESULTSThe mean prostaglandin E2 levels significantly decreased after the endodontic therapy. Significant correlations between the levels of prostaglandin E2 and the clinical features of periapical periodontitis were also found in this study.
CONCLUSIONThe results suggest that the level of prostaglandin E2 in periapical exudates reflects the state of periapical periodontitis.

OBJECTIVETo study the values of immunohistochemistry staining and cytological diagnosis by using cell block sections prepared with the effusion fluid cytology specimens.
METHODSNinety-nine effusion cytology specimens with the diagnoses of reactive mesothelial hyperplasia, atypical cells and metastatic carcinoma were enrolled into the study. The cytospin preparations/smears, cell block sections and immunohistochemical study were performed and correlated with the clinical findings and follow-up data.
RESULTSAmongst the 99 cases studied, the percentage with positive diagnosis using cytospin preparations/smears was 68.7% (68/99). The percentages with negative and equivocal diagnoses were 16.2% (16/99) and 15.1% (15/99), respectively. As for cell block sections, the percentages were 71.7% (71/99), 16.2% (16/99) and 12.1% (12/99), respectively. On the other hands, the percentages became 76.8% (76/99), 20.2% (20/99) and 3.0% (3/99), respectively, when coupled with immunohistochemical findings. The overall percentages of positive, negative and equivocal diagnoses were 77.8% (77/99), 17.2% (17/99) and 5.0% (5/99), respectively, upon clinicopathologic correlation. The difference between cytospin preparations/smears and cell block sections was not statistically significant (P > 0.05). When coupled with immunohistochemical findings or clinicopathologic correlation, the difference in rates of equivocal diagnosis however carried statistical significance (P < 0.05). The false-negative rate of immunohistochemical study applied on cell block sections was 1.0% (1/99).
CONCLUSIONSImmunohistochemistry, when applied on cell block sections, is useful in delineation of the primary origins of the tumor cells in effusion fluid cytology specimens. Combination of morphologic examination, immunohistochemical findings and clinicopathologic correlation can further improve the rate of positive diagnosis.

OBJECTIVE: To investigate the clinical characteristics of fetal hydrops and to find the antenatal ultrasound findings predictive of adverse perinatal outcome. METHODS: This is a retrospective study of 42 women with fetal hydrops who delivered in a tertiary-referral center from 2005 to 2013. Fetal hydrops was defined as the presence of fluid collection in > or =2 body cavities: ascites, pleural effusion, pericardial effusion, and skin edema. Predictor variables recorded included: maternal characteristics, gestational age at diagnosis, ultrasound findings, and identifiable causes. Primary outcome variables analyzed were fetal death and neonatal death. RESULTS: The mean gestational age at diagnosis was 29.3+/-5.4 weeks (range, 18 to 39 weeks). The most common identifiable causes were cardiac abnormality (10), followed by syndrome (4), aneuploidy (3), congenital infection (3), twin-to-twin transfusion syndrome (3), non-cardiac anormaly (2), chorioangioma (2), inborn errors of metabolism (1), and immune hydrops by anti-E antibody isoimmunization (1). Thirteen cases had no definite identifiable causes. Three women elected termination of pregnancy. Fetal death occurred in 4 cases. Among the 35 live-born babies, only 16 survived (54.0% neonatal mortality rate). Fetal death and neonatal mortality rate was not significantly associated with Doppler velocimetry indices or location of fluid collection, but increasing numbers of fluid collection site was significantly associated with a higher risk of neonatal death. CONCLUSION: The incidence of fetal hydrops in our retrospective study was 24.4 per 10,000 deliveries and the perinatal mortality rate was 61.9% (26/42). The number of fluid collection sites was the significant antenatal risk factor to predict neonatal death.

Endomyocardial biopsy (EMB) is one of the reliable methods for the diagnosis of various cardiac diseases. However, EMB can cause various complications. The purpose of this study is to evaluate the complication of transfemoral EMB with both fluoroscopic and two-dimensional (2-D) echocardiographic guidance. A total of 228 patients (148 men; 46.0+/-14.6 yr-old) who underwent EMB at Kyungpook National University Hospital from January 2002 to June 2012 were included. EMB was performed via the right femoral approach with the guidance of both echocardiography and fluoroscopy. Overall, EMB-related complications occurred in 21 patients (9.2%) including one case (0.4%) with cardiac tamponade requiring emergent pericardiocentesis, four cases (1.8%) with small pericardial effusion without pericardiocentesis, two cases (0.9%) with hemodynamically unstable ventricular tachycardia (VT), one case (0.4%) with nonsustained VT, one case (0.4%) with tricuspid regurgitation, twelve cases (5.3%) with right bundle branch block. There was no occurrence of either EMB-related death or cardiac surgery. Left ventricular ejection fraction was significantly lower (32.0+/-18.7% vs 42.0+/-19.1%, P=0.023) and left ventricular end-diastolic dimension was larger (60.0+/-10.0 mm vs 54.2+/-10.2 mm, P=0.013) in patients with EMB related complications than in those without. It is concluded that transfemoral EMB with fluoroscopic and 2-D echocardiographic guidance is a safe procedure with low complication rate.

BACKGROUND:
Epidermal growth factor receptor (EGFR) mutation non-small cell lung cancer (NSCLC) is an important subtype of lung cancer. The incidence of malignant pericardial effusion (MPCE) in EGFR-mutant NSCLC patients is high. However, there are few researches on the treatmentof this type of patients.
METHODS:
We collected data on clinical characteristics and treatment of advanced NSCLC patients who harboring EGFR mutants and MPCE between January 2010 and December 2016. The treatments were divided into three groups: oral gefitinib combined with pericardial perfusion of hydroxycamptotheci (HCPT) group (gefitinib/HCPT); intravenous chemotherapy combined with pericardial perfusion of HCPT group (chemotherapy/HCPT) and gefitinib monotherapy group. And we retrospectively analyzed patients' outcomes in three groups.
RESULTS:
In 273 advanced NSCLC patients with EGFR mutations, 29 cases had pericardial effusion, among which 6 patients with small amount of pericardial effusion were excluded, and 23 patients were analyzed. Median pericardium progression free survival (PFS) was 247 days. PFS for gefitinib/HCPT group (460 days) was superior to PFS for chemotherapy/HCPT group (94 days, P=0.008) and gefitinib monotherapy group (131 days, P=0.032). As for the efficacy of primary pulmonary lesions, the efficacy in gefitinib/ HCPT group was superior to chemotherapy/HCPT group [objective response rate (ORR): 33.3% vs 12.5%; disease control rate (DCR): 86.7% vs 62.5%]. There is no difference of ORR and DCR between gefitinib/HCPT group and gefitinib monotherapy group. No obvious adverse reaction was observed in all three groups.
CONCLUSIONS
First-line gefitinib therapy combined with pericardial perfusion of HCPT can improve pericardium PFS for advanced NSCLC patients who harboring EGFR mutants andmalignantpericardial effusion. This finding should be confirmed further through multicenter, prospective clinical trials with large sample size.
