The role of medical thoracoscopy in the treatment of pleural infections is increasingly being recognized. This study was done to assess the role of medical thoracoscopy in the management of carefully selected subset of patients with complicated parapneumonic effusions (PPEs).

We analyzed retrospective data of 164 thoracoscopic procedures performed at our center on patients with complicated PPE in the past 10 years. Patients were subjected to medical thoracoscopy based on ultrasonographic stratification and a computed tomography (CT) thorax. Medical thoracoscopy was performed after an intercostal block under conscious sedation with midazolam (2 mg) and fentanyl (50 mcg) and local anesthesia with lignocaine 2% (10-15 ml), through a single port 10 mm diameter thoracoscope.

A total of 164 patients (119 males and 45 females) underwent medical thoracoscopy during the study period. The mean age was 47.4 ± 15.9 (median, 50; range, 16-86). The final diagnosis by thoracoscopy was bacterial empyema in 93 patients and tuberculosis in 71 patients. Medical thoracoscopy was successful without subsequent intervention in 160 (97.5%) patients, two patients underwent a second procedure, in the form of decortication, and two patients died due to sepsis. There were no major procedure-related complications that required intervention.

Early adhesiolysis and drainage of fluid using medical thoracoscopy should be considered in patients with multiloculated complicated PPE after careful radiological (ultrasonography and CT) stratification, as a more cost-effective and safe method of management.

Organizing pneumonia (OP) is an idiopathic interstitial pneumonia characterized radiologically by the patchy peripheral areas of ground-glass opacities and consolidation. It is commonly associated with a variety of conditions such as connective tissue diseases (CTD), drugs, infections, malignancy, radiation exposure, post-transplant, and other interstitial pneumonia. There are no specific clinical manifestations unless there is an underlying etiology. We present a series of such cases.

The aim of the study was to identify the clinical characteristics and etiological spectrum of patients manifesting radiologically with OP pattern.

This was a retrospective analysis of clinico-radiological profile and etiological diagnosis of 23 patients, who had a radiological diagnosis of OP during the period of January 2017-September 2019.

Our patients presented with nonspecific symptoms of cough, fever, breathlessness, and occasionally with hemoptysis. The various etiologies identified were CTD (n = 4), infection (n = 2), drugs (n = 4), radiation (n = 1), chronic aspiration syndrome (n = 1), malignancy (n = 2), hypersensitivity pneumonitis (n = 1), and chronic heart failure (n = 2), and in majority (n = 7), no underlying etiology was evident and were labeled as cryptogenic organizing pneumonia.

OP is an underdiagnosed entity and is associated with numerous diseases varying from pulmonary tuberculosis to malignancy. Identification of the underlying disease process is of paramount importance as it enables the treating physician to implement necessary therapeutic interventions.

Pleural effusion (PE) is presenting symptoms of many different diseases and is often a diagnostic challenge. Negative cytology in the malignant PE requires more complicated diagnostic procedures, such as closed pleural biopsy or thoracoscopic pleural biopsy. Not all the patients will be fit for such invasive procedures due to high risk. Tumor markers seem to be a promising alternative and have been proposed to aid in the differentiation of the PE etiology.

The objective of the study was to evaluate the diagnostic value of pleural fluid carcinoembryonic antigen (CEA) in differentiation between malignant and nonmalignant PEs and to compare adenosine deaminase (ADA) levels with respect to malignant and nonmalignant PE.

It was a prospective observational study. Patients who presented with undiagnosed exudative PE during the time period 2016-2018 were studied. Pleural fluid was subjected to all routine investigations such as sugar, protein, lactate dehydrogenase, ADA, and CEA.

A total of 100 patients were d specificity of 73% in diagnosing of malignant PE. ADA levels lesser than 16.5 U/L were seen in patients with malignant PE, but less sensitive and specific compared to CEA. Combined ADA and CEA levels had higher sensitivity than CEA alone.
Pulmonary neuroendocrine tumors (NETs) comprise a spectrum of tumors ranging from indolent to highly aggressive neoplasm. This study aims to study the clinicopathological and immunohistochemical features of NETs and assess the sensitivity of various IHC markers.

All consecutive cases of pulmonary NETs diagnosed from January 2016 to June 2019 were analyzed retrospectively. The routine hematoxylin- and eosin-stained sections along with immunohistochemistry (IHC) slides were reviewed. IHC was done using a panel of markers which included synaptophysin, chromogranin, CD56, thyroid transcription factor-1 (TTF-1), p-40, napsin-A, and ki67.

Of total number of 53 patients, diagnosis was made on biopsy in 40 patients and resection specimen in 13 patients. Small cell lung carcinoma was the most common (31 cases), followed by 16 cases of typical carcinoid, 5 cases of atypical carcinoid, and 1 case of combined SCLC. selleck products Both synaptophysin and chromogranin were positive in all the cases of typical carcinoid. Synaptophysin had better sensitivity than chromogranin in atypical carcinoid and small cell carcinoma. CD56 was positive in 8 out of 9 cases done. TTF-1 was negative in all the cases of typical carcinoid. The sensitivity of TTF-1 in small cell carcinoma was 85.19%. The mean Ki67 labeling index was 1.4%, 6.6%, and 65.6% in typical, atypical carcinoid, and small cell carcinomas, respectively.

Synaptophysin was more sensitive than chromogranin, especially in atypical carcinoid and small cell carcinoma. TTF-1 along with high Ki67 differentiates small cell carcinoma from carcinoid.
