Acute eosinophilic pneumonia (AEP) is an uncommon inflammatory lung disease, and limited data exist concerning the clinical characteristics and factors that influence its occurrence. We retrospectively reviewed the records of AEP patients treated at Korean military hospitals between January 2007 and December 2013. In total, 333 patients were identified; their median age was 22 years, and all were men. All patients presented with acute respiratory symptoms (cough, sputum, dyspnea, or fever) and had elevated levels of inflammatory markers including median values of 13,185/microL for white blood cell count and 9.51 mg/dL for C-reactive protein. All patients showed diffuse ground glass opacity/consolidation, and most had pleural effusion (n = 265; 80%) or interlobular septal thickening (n = 265; 85%) on chest computed tomography. Most patients had normal body mass index (n = 255; 77%), and only 30 (9%) patients had underlying diseases including rhinitis, asthma, or atopic dermatitis. Most patients had recently changed smoking habits (n = 288; 87%) and were Army personnel (n = 297; 89%).The AEP incidence was higher in the Army group compared to the Navy or Air Force group for every year (P = 0.002). Both the number of patients and patients with high illness severity (oxygen requirement, intensive care unit admission, and pneumonia severity score class > or = III) tended to increase as seasonal temperatures rose. We describe the clinical characteristics of AEP and demonstrate that AEP patients have recently changed smoking habits and work for the Army. There is an increasing tendency in the numbers of patients and those with higher AEP severity with rising seasonal temperatures.

OBJECTIVE: The purpose of this study was to retrospectively evaluate the diagnostic accuracy and complications of CT-guided core needle biopsy (CT-guided CNB) of pleural lesion and the possible effects of influencing factors. MATERIALS AND METHODS: From September 2007 to June 2013, 88 consecutive patients (60 men and 28 women; mean [+/- standard deviation] age, 51.1 +/- 14.4 years; range, 19-78 years) underwent CT-guided CNB, which was performed by two experienced chest radiologists in our medical center. Out of 88 cases, 56 (63%) were diagnosed as malignant, 28 (31%) as benign and 4 (5%) as indeterminate for CNB of pleural lesions. The final diagnosis was confirmed by either histopathological diagnosis or clinical follow-up. The diagnostic accuracy, sensitivity, specificity, positive predictive value (PPV), negative predictive value (NPV), and complication rates were statistically evaluated. Influencing factors (patient age, sex, lesion size, pleural-puncture angle, patient position, pleural effusion, and number of pleural punctures) were assessed for their effect on accuracy of CT-guided CNB using univariate and subsequent multivariate analysis. RESULTS: Diagnostic accuracy, sensitivity, specificity, PPV, and NPV were 89.2%, 86.1%, 100%, 100%, and 67.8%, respectively. The influencing factors had no significant effect in altering diagnostic accuracy. As far as complications were concerned, occurrence of pneumothorax was observed in 14 (16%) out of 88 patients. Multivariate analysis revealed lesion size/pleural thickening as a significant risk factor (odds ratio [OR]: 8.744, p = 0.005) for occurrence of pneumothorax. Moreover, presence of pleural effusion was noted as a significant protective factor (OR: 0.171, p = 0.037) for pneumothorax. CONCLUSION: CT-guided CNB of pleural lesion is a safe procedure with high diagnostic yield and low risk of significant complications.

OBJECTIVETo analyze the clinical characteristics and diagnosis of 2 cases with chylothorax due to primary lymphatic dysplasia and to elevate pediatrician's recognition level for this disease.

METHODClinical manifestations of the children were retrospectively analyzed. Primary lymphatic dysplasia was diagnosed by lymphoscintigraphy.

RESULTThe first patient was a male aged 2-year-7-month who presented with a history of tachypnea for 43 days, fever and sore throat for 5 days at the early stage of the illness. He had a history of external injury before his illness. Physical examination showed his left chest bulging and left side diminished breath sound. His pleural effusion showed dark red (It was divided into two layers after standing, the upper layer turned into milky white, and the lower turned into hemorrhagic liquid) . White blood cell (WBC) count was 9 000×10(6)/L, mononuclear cell was 0.9, polykaryocytes was 0.1, triglyceride was 12.37 mmol/L in the pleural effusion. Contrast-enhanced lung CT (revascularization) showed pericardial effusion and a massive left sided pleural effusion. The second patient was a male aged 9 years and 6 months, who presented with a history of cough for 24 days, intermittent fever, vomiting, abdominal pain for 19 days, and edema of lower limbs for 4 days. Physical examination showed edema in both eyelids, lower extremities and scrotum. The level of albumin was 14 g/L and the titer of Mycoplasma pneumoniae IgM was 1: 320 in the serum. His hydrothorax pleural effusion showed milk white. White blood cell (WBC) count was 74×10(6)/L, mononuclear cell was 0.78, polykaryocytes was 0.22, triglyceride was 1.01 mmol/L in the pleural effusion. Chyle test showed positive in his pleural effusion and seroperitoneum. High-resolution CT of the lung revealed bilateral interstitial and parenchymal infiltration and both sided pleural effusion. Abdominal ultrasound showed giant hypertrophy of the gastric mucosa and massive ascites. Gastroscopy showed giant hypertrophy of the gastric mucosa. Lymphoscintigraphy revealed primary lymphatic dysplasia in both children.

CONCLUSIONPrimary lymphatic dysplasia might occur in children and result in dropsy of serous cavity (chylothorax, chylopericardium, chylous ascites). Dropsy of serous cavity showed bloody or milk white. WBC count might elevate with lymphocyte increasing mostly, triglyceride was often higher than 1.0 mmol/L in dropsy of serous cavity. Primary lymphatic dysplasia can be diagnosed by lymphoscintigraphy.

BACKGROUND/AIMS: Intra-abdominal hypertension (IAH) is being increasingly reported in patients with severe acute pancreatitis (SAP) with worsened outcomes. The present study was undertaken to evaluate intra-abdominal pressure (IAP) as a marker of severity in the entire spectrum of acute pancreatitis and to ascertain the relationship between IAP and development of complications in patients with SAP. METHODS: IAP was measured via the transvesical route by measurements performed at admission, once after controlling pain and then every 4 hours. Data were collected on the length of the hospital stay, the development of systemic inflammatory response syndrome (SIRS), multiorgan failure, the extent of necrosis, the presence of infection, pleural effusion, and mortality. RESULTS: In total, 40 patients were enrolled and followed up for 30 days. The development of IAH was exclusively associated with SAP with an APACHE II score > or =8 and/or persistent SIRS, identifying all patients who were going to develop abdominal compartment syndrome (ACS). The presence of ACS was associated with a significantly increased extent of pancreatic necrosis, multiple organ failure, and mortality. The mean admission IAP value did not differ significantly from the value obtained after pain control or the maximum IAP measured in the first 5 days. CONCLUSIONS: IAH is reliable marker of severe disease, and patients who manifest organ failure, persistent SIRS, or an Acute Physiology and Chronic health Evaluation II score > or =8 should be offered IAP surveillance. Severe pancreatitis is not a homogenous entity.

OBJECTIVETo study the clinical characteristics of Streptococcus pneumonia-associated hemolytic uremic syndrome (SP-HUS) in children.

METHODClinical and laboratory data of a pediatric case of SP-HUS were retrospectively analyzed and the key points of diagnosis and therapy were reviewed.

RESULTAn 18-month old girl was admitted with chief complaint of fever and cough for 5 days combined with mild labored breath. Breath sound was found weakened in right lung with lower lobe dullness on percussion. Laboratory tests revealed: WBC 3.7×10(9)/L, Hb 83 g/L, PLT 11×10(9)/L, C-reactive protein (CRP) > 180 mg/L. Morphological study of the RBCs showed marked anisocytosis and schistocytosis. Urinalysis showed 42.66 RBCs per high-power field, occult blood (+++), proteinura (++++). Streptococcus pneumoniae was isolated from blood, pleural fluid and sputum. Serotyping with simplified chessboard system was 3. The direct Coombs test was positive. Serum complement levels (C3 and C4) were depressed at 0.699 g/L, 0.064 g/L, respectively. Chest X-ray showed pleural effusion and infection of the right hemothorax. The computerized tomographic scan of the chest revealed pneumatoceles in the right lower lobe. The diagnosis on admission we considered was SP-HUS. Intravenous antibiotic therapy (vancomycin + cefoperazone/sulbactam) was administered. The renal replacement theraphy was administered to maintain electrolyte and fluid balances and adequate nutrition. Transfusions of washed red blood cells were administered to correct the anemia. One month after admission the patient was good with recovery. Liver and renal function recovered and the pneumonia was resolving, anemia and platelets were corrected. The direct Coombs test turned to be negative. Serum complement levels (C3 and C4) were normal. After 3-month follow-up, no clinical anomalies were detected.

CONCLUSIONSP-HUS should be suspected when the following occurs in the context of pneumococcal infections: microangiopathic hemolytic anemia, thrombocytopenia, acute renal failure and a positive Coombs test result. Serotype 3 of SP was associated with HUS.

OBJECTIVETo evaluate the incidence of extrahepatic collateral arteries involved in the blood supply to hepatocellular carcinoma (HCC) and to assess the technical success rates and complications of transcatheter arterial chemoembolization (TACE) through the collaterals.

METHODS1356 TACE procedures were performed in 874 consecutive patients through extrahepatic collateral pathways to HCC between August 2006 and August 2010 in our department. The extrahepatic collateral pathways to HCC revealed on angiography were retrospectively evaluated. TACE through extrahepatic collaterals using iodized oil and gelatin sponge particles was performed when a catheter was advanced into the feeding branch to avoid nontarget embolization.

RESULTSIncidences of collateral source to HCC were 76.3% from the right inferior phrenic artery (RIPA), 2.4% from the left inferior phrenic artery (LIPA), 6.9% from the right and 0.4% from the left internal mammary arteries (RIMA, LIMA), 2.9% from the right intercostal artery (RICA), 2.0% from the omental artery, 0.8% from the right or middle colic artery, 2.3% from the cystic artery, 1.3% from the left and 1.1% from the right gastric arteries (LGA, RGA), 3.5% from the right renal capsular artery (RRCA), right middle adrenal artery (RMAA) and right inferior adrenal artery (IAA). Technical success rates of TACE were 95.9% in the RIPA, 93.8% in the LIPA, 100.0% in the RIMA and LIMA, 55.0% in the RICA, 77.8% in the omental artery, 63.6% in the colic artery, 67.7% in the cystic artery, 76.5% in the LGA, 73.3% in the RGA and 95.8% in the RRCA, RMAA, and RIAA. Complications included skin erythema and necrosis after TACE through the RIMA, skin erythema after TACE through the RICA, cholecystitis after TACE through the cystic artery (n = 1), and pleural effusion, basal atelectasis and hiccup after TACE through the IPA.

CONCLUSIONTACE through extrahepatic collaterals is safe and feasible, and with a high success rate in the treatment of hepatocellular carcinoma.

OBJECTIVETo evaluate the value of cytomorphologic and immunocytochemical approaches in the diagnosis of hematologic neoplasms in serous effusion.

METHODSThe cytospin and Thinprep smears of effusion specimens were prepared from 23 cases of lymphoid malignancies with histological confirmation and 30 cases of benign effusions used as control. Morphological assessment of the cellular components was conducted, including the ratio of mesothelium to lymphocyte, karyomorphism of lymphoid cell and the presence of apoptosis and mitosis. Immunocytochemical study was performed in all the cases, with flow cytometry in one case.

RESULTSAmong the 23 tumor cases, 14 represented disease relapse, and in the remaining nine cases, the serous effusion was the primary manifestation. The proportion of mesothelium was low in the tumor group, being less than 10% in 20 cases (87.0%, 20/23). It was more than 10% in most of benign cases (20/30, 66.7%). Lymphoid cells were prominent (> 80% cells) in 69.6% of the tumor cases, and the cellular component in some control cases (63.3%, 19/30) showed fewer lymphocytes. Nipple-like projection of lymphocytic nuclei could be detected in almost all the tumor cases (91.3%, 21/23), but was occasionally found in the control group (26.7%, 8/30). Apoptosis and mitosis were obvious in lymphomatous effusion, but observed in only 6.7% of the control cases. Significant difference of the previously mentioned cytomorphologic features existed between the tumor and control groups (P < 0.01). The results of immunocytochemical staining in cell block were identical to the corresponding immunohistochemistry, and one case of mantle cell lymphoma was confirmed by flow cytometry. The cytologic findings seen in all the 23 studied cases were in agreement with the corresponding histologic diagnosis.

CONCLUSIONSSome cytomorphologic features, including decreased number of mesothelium, increased number of lymphoid cells, nuclear nipple-like projection, and the presence of apoptosis and mitosis, are very useful for diagnosing lymphoid malignancy in serous effusion. Immunocytochemistry is an important approach to the cytodiagnosis and classification of lymphoma.

OBJECTIVETo evaluate therapeutical effect of combined hepatic resection and fenestration on patients with severe adult polycystic liver disease (APLD).

METHODSPreoperative clinical symptoms, postoperative complications and prognoses from 33 patients with severe adult polycystic liver disease (APLD) treated with combined hepatic resection and fenestration were recorded. According to the number and location of cysts before surgery and the remnant liver parenchyma after operation, all patients were classified into two types: class A and B. And patients in each type were further classified into three grades: Grade I, II and III. The frequency of postoperative complications of two types patients was compared.

RESULTSThe mean follow-up time was 57 months. There were three patients with recurrence of symptoms at 81, 68 and 43 mouths after operation. Two patients died of renal failure due to polycystic kidney disease at 137 and 85 mouths after operation. And one patient with postoperative hepatic inadequacy received an orthotopic liver transplantation. The total number of patients with postoperative complications was 26 cases, including one patient with bleeding, two patients with bile leakage, fourteen patients with mild ascites, twelve patients with severe ascites and eighteen patients with pleural effusion, and the overall incidence was 78.8%. There were 22 patients with imaging data, including 6 patients within A type and sixteen patients within B type. The frequencies of postoperative complications were 4 and 31, respectively, and the difference was statistically significant (Chi-square test = 4.99, P less than 0.05).

CONCLUSIONCombined hepatic resection and fenestration is a safe and acceptable procedure for the treatment of severe APLD.
