Background and Aim: Cardiac disease is common in cats, and concurrent pleural effusion can worsen the prognosis. However, the definitive diagnosis of feline cardiac disease by echocardiography is limited in some areas. This study was designed to determine the indicators from fluid analysis obtained from pleural effusion to help diagnose cardiac disease in cats. Materials and Methods: A retrospective study was conducted. Data of 61 cats with pleural effusion were retrieved. The cats were divided into two groups: Cardiac disease (n=34) and non-cardiac disease (n=27) groups. Sex, neuter status, breed, age, weight, physical findings, fluid analysis results, radiographic findings, echocardiographic findings, and the presence of other diseases or conditions were recorded. Results: The Chi-square test showed the relationship between cardiac disease and the presence of abnormal heart sounds (p=0.0003), the N-terminal pro-B-type natriuretic peptide-positive result from serum samples (p=0.046), the presence of arterial thromboembolism (p<0.00001), and the presence of radiographic evidence of cardiomegaly and pulmonary edema (p=0.0002 and 0.001, respectively). The Mann–Whitney U-test showed a significant difference in protein concentration and specific gravity between the cardiac and non-cardiac disease groups (p=0.012 and 0.009, respectively). The decision tree classification method showed that protein concentrations of ≤3 g/dL were related to cardiac disease (sensitivity, 41.2% and specificity, 92.6%). Conclusion: The protein concentration in the pleural fluid may be used to distinguish cardiac and non-cardiac diseases in cats.

ABSTRACTPancreatico‑pleural fistula is a rare but serious complication of acute and chronic pancreatitis. The pleural effusion caused by pancreatico‑pleural fistula is usually massive and recurrent. It is predominately left‑sided but right‑sided and bilateral effusion does occur. We report four cases of pancreatico‑pleural fistula admitted to our hospital. Their clinical presentation and management aspects are discussed. Two patients were managed by pancreatic endotherapy and two patients were managed conservatively. All four patients improved symptomatically and were discharged and are on regular follow‑up. Most of these patients would be evaluated for their breathlessness and pleural effusion delaying the diagnosis of pancreatic pathology and management. Hence, earlier recognition and prompt treatment would help the patients to recover from their illnesses. Pancreatic pleural fistula diagnosis requires a high index of suspicion in patients presenting with chest symptoms or pleural effusion. Extremely high pleural fluid amylase levels are usual but not universally present. A chest X‑ray, pleural fluid analysis, and abdominal imaging (magnetic resonance cholangiopancreatography/magnetic resonance imaging abdomen more useful than contrast‑enhanced computed tomography abdomen) would clinch the diagnosis. Endoscopic retrograde cholangiopancreatography with stent or sphincterotomy should be considered when pancreatic duct (PD) reveals a stricture or when medical management fails in patients with dilated or irregular PD. Surgical intervention may be indicated in patients with complete disruption of PD or multiple strictures.

Backgrounds: Tuberculosis pleural effusion is the most common extrapulmonary TB after lymphadenitis TB, but a definite diagnosis is still a challenge. Pleural biopsy has historically been the gold standard procedure for the diagnosis of pleural tuberculosis. GenXpert® is a computerize test based in nucleic acid amplification tahat automatically detect MTB and rifampicin resistance. This study aimed to prove the correlation between pleural fluid GenXpert® and histopathological findings of pleural biopsy in patients with pleural tuberculosis. Methods: This study used an observational analytic design with a cross-sectional design conducted in Dr. Soetomo Hospital, Surabaya in March-June 2017. Statistic analysis was using chi square test and contingensi coofisient. The pleural GenXpert® was tested in 23 patients with pleural effusion and their biopsy speciments underwent histopathological analysis. Results: Histopathological findings of pleural biopsy was positive in 4 subjects and pleural fluid GenXpert® resulted positive in 6 subjects. There was significant correlation between pleural fluid GenXpert® and histopathological findings of specimen pleural biopsy in patients with pleural tuberculosis (P=0.040) with moderate strenght (P=0.014). Sensitivity and specificity of pleural fluid GenXpert® were 75.0% dan 84.2% respectively. Conclusions: There was significant correlation between pleural fluid GenXpert® and histopathological findings of pleural biopsy in patients with pleural tuberculosis.

Background: Approximately one million patients develop pleural effusion every year. It is a common clinical disorder and is either a manifestation or a complication of one or other respiratory or non-respiratory disorders. It leads to serious prognosis, if not diagnosed and treated properly. To calculate SEAG and Light’s criteria and to compare SEAG with Light’s criteria in analyzing pleural effusions.Methods: A total of hundred patients were selected for the study. Pleural fluid of patients who met the inclusion and exclusion criteria were collected, when pleural fluid is being tapped for diagnostic thoracocentesis. Venous blood sample was collected along with diagnostic thoracocentesis or within 24 hours of thoracocentesis.  Written informed consent was obtained from them for thoracocentesis.Results: In our study we compared the clinical outcome with outcome as per Pleural fluid/Serum protein ratio (p value of <0.0001), pleural fluid/serum LDH (p value of <0.0001) and pleural fluid LDH (p value of <0.0001) separately and the p values were statistically significant. The sensitivity, specificity, PPV and NPV of Light’s criteria were 77.2%, 100%, 100%, 93.9% respectively. We compared Light’s criteria outcome with clinical outcome and the difference was statistically significant (p value of <0.0001). SEAG showed 100% sensitivity, 97.43% specificity, 91.6% PPV and is 91.66% and NPV is 100%. We compared the clinical outcome with SEAG and there was statistically significant difference (p value of <0.0001). We compared SEAG with Light’s criteria and the difference was statistically significant (p <0.0001). We compared Light’s plus pleural fluid protein gradient with SEAG and the difference is statistically significant (p value of <0.0001).Conclusions: SEAG is more sensitive for classifying transudates and more specific for exudates than Light’s criteria.

Exudative Pleural Effusion

Pleural effusion discusses the radiographic and computed tomography (CT) manifestations of this entity. Pleural effusion is classified based on pleural fluid analysis using Light’s criteria: transudative and exudative. Free pleural fluid collects in the most dependent aspect of the pleural space due to gravitational effects. It exhibits a meniscus configuration on upright chest radiography. Pleural effusion in a supine or semiupright patient is more difficult to identify but may be suspected in cases with a homogeneous or gradient-like opacity over the lower hemithorax, elevation of the hemidiaphragm contour, or an apical cap. Subpulmonic pleural effusion manifests with lateral displacement of the apex of the ipsilateral hemidiaphragm contour and increased distance between the gastric air bubble and pseudodiaphragmatic contour. Exudative pleural effusion should be suspected in cases with CT findings of pleural thickening, enhancement, septations, and/or loculations.

Background: Pleural effusion is the pathologic accumulation of fluid in the pleural space. The fluid analysis yields important diagnostic information, and in certain cases, fluid analysis alone is enough for diagnosis. Analysis of pleural fluid by thoracentesis with imaging guidance helps to determine the cause of pleural effusion. The purpose of this study was to assess the accuracy of computed tomography (CT) in characterizing pleural fluid based on attenuation values and CT appearance. Materials and Methods: This prospective study included 100 patients admitted to Gandaki Medical College and Teaching Hospital, Pokhara, Nepal between January 1, 2017 and February 28, 2018. Patients who were diagnosed with pleural effusion and had a chest CT followed by diagnostic thoracentesis within 48 hours were included in the study. Effusions were classified as exudates or transudates using laboratory biochemistry markers on the basis of Light’s criteria. The mean attenuation values of the pleural effusions were measured in Hounsfield units in all patients using a region of interest with the greatest quantity of fluid. Each CT scan was also reviewed for the presence of additional pleural features. Results: According to Light’s criteria, 26 of 100 patients with pleural effusions had transudates, and the remaining patients had exudates. The mean attenuation of the exudates (16.5 ±1.7 HU; 95% CI, range, -33.4 – 44 HU) was significantly higher than the mean attenuation of the transudates (11.6 ±0.57 HU; 95% CI, range, 5 - 16 HU), (P = 0.0001). None of the additional CT features accurately differentiated exudates from transudates (P = 0.70). Fluid loculation was found in 35.13% of exudates and in 19.23% of transudates. Pleural thickening was found in 29.7% of exudates and in 15.3% of transudates. Pleural nodule was found in 10.8% of exudates which all were related to the malignancy. Conclusion: CT attenuation values may be useful in differentiating exudates from transudates. Exudates had significantly higher Hounsfield units in CT scan. Additional signs, such as fluid loculation, pleural thickness, and pleural nodules were more commonly found in patients with exudative effusions and could be considered and may provide further information for the differentiation.

Background: pleural effusion is the common findings in patients presenting with cardiopulmonary symptoms but specific studies are lacking in Nepal. Objective: The main objective of this study is to find out the various causes of pleural effusion, their mode of clinical presentation and laboratory analysis of blood and pleural fluid to aid diagnosis of patients with pleural effusion. Materials and methods: Retrospective data from July 2009 to July 2007 from all the cases diagnosed with pleural effusion were taken. Altogether 100 cases diagnosed with pleural effusion by chest X-ray (Posterior- Anterior and Lateral view) and Ultrasonogram of the chest were studied. The following parameters were analysed: Patients demographic profile, causes, location (Unilateral, Bilateral), Blood haemoglobin and count, sputum profile, Monteux test, chest Xray and USG findings and pleural fluid analysis[Biochemical, Haematological, Microbiological(culture and stain) and cytological]. This study was analysed by using SPSS 16. Results: The mean age of the patient was 44.89 ± 21.59 and must patients with pleural effusion belong to age group 21- 30. Most common cause of pleural effusion was found to be tubercular effusion followed by parapneumonic effusion. Right sided effusion was seen in most cases of tubercular parapneumonic and malignant effusion whereas bilateral effusion was seen in 87.5% of the patient (7 out of 8) having congestive heart failure and all cases of renal disease (4 out of 4). Shortness of breath (83%), cough (67%) and fever (66%) are the most common mode of clinical presentation. Conclusion: Our study concluded that the most common cause of unilateral pleural effusion is tuberculosis followed by parapneumonic effusion and most cases of those belong to younger age group (21 -30yrs) and most common cause of bilateral pleural effusion is congestive cardiac failure.

Objectives: Pleural effusion is a common reason for hospital admission with thoracentesis often required to diagnose an underlying cause. This study aimed to determine if the imaging characteristics of TUS effectively differentiates between transudative and exudative pleural fluid. Methods: Patients undergoing TUS with pleural fluid analysis were retrospectively identified at a single center between July 2016 and March 2018. TUS images were interpreted and characterized by established criteria. We determined diagnostic performance characteristics of image criteria to distinguish transudative from exudative pleural effusions.  Results: 166 patients underwent thoracentesis for fluid analysis of which 48% had a known malignancy. 74% of the pleural effusions were characterized as exudative by Light’s Criteria. TUS demonstrated anechoic effusions in 118 (71%) of samples. The presences of septations on TUS was highly specific in for exudative effusions (95.2%) with high positive predictive values (89.5%) and likelihood ratio (2.85). No TUS characteristics, even when adjusting for patient characteristics such as heart failure or malignancy, were sensitive for exudative effusions.  Conclusions: Among our cohort, anechoic images did not allow reliable differentiation between transudative and exudative fluid. Presence of complex septated or complex homogenous appearance was high specific and predictive of exudative fluid.

Abstract Background There have been many studies on the clinical characteristics of neutrophilic, lymphocytic, and/or eosinophilic pleural effusion. While caring for patients with pleural effusion, we found that histiocytic pleural effusion (HisPE) was not uncommon. However, few studies have explored HisPE. The purpose of the present study was to determine the clinical characteristics and etiologies of HisPE. Methods In this retrospective study, HisPE was defined as pleural fluid white blood cells comprised of ≥ 50% histiocytes. Using a clinical data warehouse, patients with HisPE among all patients aged > 18 years who underwent thoracentesis and pleural fluid analysis between January 2010 and December 2019 at Ulsan University Hospital were enrolled. A total of 295 (9.0%) of 3279 patients who underwent thoracentesis were identified as HisPE patients. Among them, 201 with exudative HisPE were included. Clinical characteristics and etiologies were extracted from medical records and analyzed. Results Among the 201 patients with exudative HisPE, the major causes were malignant pleural effusion (n = 102 [50.7%]), parapneumonic effusion (n = 9 [4.5%]), and tuberculous pleurisy (n = 9 [4.5%]). In the 102 patients with malignant pleural effusion, the main types of cancer were lung (n = 42 [41.2%]), breast (n = 16 [15.7%]), and stomach cancer (n = 11 [10.8%]). Among lung cancers, adenocarcinoma (n = 34 [81.0%]) was the most common histology. Conclusions The leading cause of exudative HisPE was malignancy, particularly lung cancer. Physicians should consider the possibility of malignant disease if histiocytes are predominantly present in pleural effusion.
