BACKGROUND: Malignant pleural effusion (PE) was generally defined as pleural effusion containing tumors with poor prognosis. Some kinds of undefined pleural effusions due to too small amount of effusion had poor prognosis too. This study aimed to analyze the clinical characteristics and prognostic factors of patients who suffered from limited-stage small cell lung cancer (LS-SCLC) complicated with pleural effusion. METHODS: A retrospective analysis included 542 patients who were diagnosed with LS-SCLC and had treatment in our hospital from October 2007 to January 2016. We had observed 109 patients who were diagnosed with pleural effusion at their first visit to the doctor. We analyzed the clinical characters, survival time and the prognostic factors of the 109 patients. Our main observation targets were overall survival (OS) and progression free survival (PFS). RESULTS: The median OS and PFS of whole group were 29.4 and 18.2 months. Before treatment, survival time of patients with PE were significantly shorter than patients without PE (median OS: 21.0 vs 31.7 months; median PFS: 14.1 vs 9.1 months; Log-rank, P=0.001, P=0.014). Multi-factor analysis of multivariate Cox shows PE was the independent prognostic factor of LS-SCLC (P=0.04). Single factor analysis showed factors affecting PE patient's survival time included clinical stages, lymph node (LN) stages, KPS scores, pulmonary atelectasis and the state of pleural after treatment. Cox multi-factor analysis reminded that the state of pleural effusion after treatment was the independent prognostic factor of LS-SCLC complicated with pleural effusion (P=0.016). There were three groups was apportioned patients without pleural effusion before treatment (group 1; n=433), patients whose pleural effusion disappeared after treatment (group 2; n=67) and patients whose pleural effusion didn't disappear after treatment (group 3; n=32).The median OS were 31.7, 23.2, 16.8 months in the group 1, 2, 3 and the median PFS were 19.1, 17.9, 11.4 months. Obvious difference was noted by the comparison of survival time of these three groups (Log-rank P<0.001, P<0.002). The difference between group 2 and group 3 was significant (Log-rank P=0.046, P=0.013) while no obvious difference was noted during comparison of group 1 and group 2. For patients who have LS-SCLC complicated with PE, there is no remarkable difference between chemoradiotherapy and chemotherapy alone. CONCLUSIONS The survival time of patients who suffered from limited-stage small cell lung cancer complicated with pleural effusion was obviously shortened. The disappearing of pleural effusion after treatment was the independent favorable prognostic factor of survival. How to treat needed further investigation.

BACKGROUND/AIMS: The mortality rate of pyogenic liver abscess (PLA) has decreased dramatically, but it remains a potentially life threatening disease. Most cases are cryptogenic or occur in elderly men with underlying biliary tract disease. Although several studies have addressed the characteristics and etiology of PLA, research on factors affecting PLA-associated mortality is lacking. This study intended to identify the clinical and radiological features, pathogens, complications, and predictors of mortality in Korean PLA patients. METHODS: The medical records of 231 PLA patients diagnosed at Yeungnam University Medical Center between January 2010 and January 2014 were analyzed. A diagnosis of PLA was made based on imaging studies and blood and abscess cultures. The clinical, radiological, and laboratory findings of patients were analyzed. RESULTS: The mean patient age was 64.0±12.9 years and the male to female ratio was 1.5:1. Klebsiella pneumoniae was the predominant organism isolated from hepatic abscesses (69.9%) and blood (74.2%). The most common complication was pleural effusion (35.8%) and most common co-infection was cholangitis (8.2%). The overall mortality rate of PLA was 6.9% (16/231), and was significantly higher in patients with a history of liver abscess (OR 5.970, 95% CI 1.207-29.529; p=0.028), bilirubinemia (>2 mg/dL) (OR 9.541, 95% CI 2.382-38.216; p=0.001), thrombocytopenia (<140×10(3)/µL) (OR 4.396, 95% CI 1.130-17.106; p=0.033), or anemia (<12 g/dL) (OR 13.277, 95% CI 1.476-119.423; p=0.021). CONCLUSIONS: The prognosis of PLA appears to be dependent on underlying pathologies and severity of condition. More aggressive treatment should be considered if a poor prognosis is expected.

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: We aimed to describe radiologic signs and time-course of imatinib-associated fluid retention (FR) in patients with gastrointestinal stromal tumor (GIST), and its implications for management. MATERIALS AND METHODS: In this Institutional Review Board-approved, retrospective study of 403 patients with GIST treated with imatinib, 15 patients with imaging findings of FR were identified by screening radiology reports, followed by manual confirmation. Subcutaneous edema, ascites, pleural effusion, and pericardial effusion were graded on a four-point scale on CT scans; total score was the sum of these four scores. RESULTS: The most common radiologic sign of FR was subcutaneous edema (15/15, 100%), followed by ascites (12/15, 80%), pleural effusion (11/15, 73%), and pericardial effusion (6/15, 40%) at the time of maximum FR. Two distinct types of FR were observed: 1) acute/progressive FR, characterized by acute aggravation of FR and rapid improvement after management, 2) intermittent/steady FR, characterized by occasional or persistent mild FR. Acute/progressive FR always occurred early after drug initiation/dose escalation (median 1.9 month, range 0.3-4.0 months), while intermittent/steady FR occurred at any time. Compared to intermittent/steady FR, acute/progressive FR was severe (median score, 5 vs. 2.5, p = 0.002), and often required drug-cessation/dose-reduction. CONCLUSION: Two distinct types (acute/progressive and intermittent/steady FR) of imatinib-associated FR are observed and each type requires different management.

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 explore the value of pleural biopsy in the diagnosis of tuberculous pleurisy in children.

METHODFifty-one cases with tuberculous pleurisy, whose diagnosis was established according to the clinical diagnostic criteria of the child pulmonary tuberculosis formulated by the Chinese Medical Association (CMA) in 2006, after pleural biopsy hospitalized in Children's Hospital of Chongqing Medical University from Jan. 1, 2007 to Jan. 1, 2013 were enrolled into this study. Clinical symptoms, history traits, laboratory examination, imaging tests, pleural fluid characteristics and the results of pleural biopsy were retrospectively analyzed. Medical records of the cases who were diagnosed with tuberculous pleurisy by histological examination were reviewed to assess tuberculosis detection rate of pleural biopsy and to get the percentage of cases with a preoperative diagnosis inconsistent with the final diagnosis.

RESULTThere were 35 boys and 16 girls, and the mean age was (9.7 ± 3.5) years. The common symptoms included fever (82%), cough (71%) , chest pain (23%), weakness (10%) and shortness of breath (10%); 27% (14/51) children had shown tuberculosis toxic symptoms; 76% (39/51) patients had BCG vaccination history; 12% (6/51) cases had a history of contact with tuberculosis patients. The positive rates of the tuberculin skin test, serum tuberculosis antibody detection, detection of Mycobacterium tuberculosis DNA by polymerase chain reaction, acid-fast bacillus test of sputum (or gastric juice) smear, acid-fast bacilli (AFB) smear and culture of pleural effusion were respectively 61% (20/33), 6% (3/46), 0 (0/12), 4% (1/27), 22% (7/32). Pleural effusion was found by using imaging tests in 50 cases, among whom 28 cases (55%) with encapsulated effusion, and the multilocular cysts separated by fibrous tissue in 12 patients (23%) . Other features included pleural thickening (53%) , hilar and mediastinal lymph-nodes enlargement (14%) and white nodules of calcification (10%) . Thoracocentesis was performed in 31 cases, and pleural effusion obtained from which were exudative. The cell count, mainly mononuclear cells, increased in 28 patients (90%) . Among the 51 children investigated, 47 (92%) were histologically diagnosed to be tuberculous pleurisy. The typical pathologic changes of tuberculosis (caseous necrosis, granulomas, Langhans' giant cells and inflammatory cell infiltration) were observed in 40 cases, granulomatous inflammation without caseous necrosis were the main manifestations in 7 other patients. The pathological changes of the remaining 4 cases were not consistent with the pathological characteristics of tuberculosis. All 47 cases were given a preoperative diagnosis of tuberculous pleurisy (32%), purulent pleurisy (51%) and pleural effusion of unknown origin (17%) respectively before pleural biopsy. Therefore, the tuberculosis detection rate of pleural biopsy was 92%, and the preoperative misdiagnosis rate was 68%.

CONCLUSIONPleural biopsy was of great diagnostic value for children with tuberculous pleurisy.

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.
