Familial Mediterranean fever (FMF) is autoinflammatory disorder characterized by sporadic attacks of fever, peritonitis, pleuritis, and arthritis. It is mainly seen in patients from Mediterranean origins, but it is now reported more frequently in Europe and North America due to immigration. To analyze the data on the cardiovascular manifestations in FMF patients, we searched PubMed using the terms "Familial Mediterranean Fever" or "FMF" in combination with other key words including "cardiovascular diseases" "pericardial diseases" "atherosclerosis" "coronary artery diseases" "cardiomyopathy" "pulmonary hypertension" or "valvular diseases...

Pleural macrophages play critical roles in pathogenesis of tuberculous pleuritis, but very little is known about their response to anti-tuberculosis antibiotics treatment. Here, we examined whether and how pleural macrophages change in phenotype, transcription and function following antibiotics treatment in patients with tuberculous pleuritis. Results show pro-inflammatory cytokines were down-regulated significantly post antibiotic treatment in the pleural effusions and pleural macrophages up-regulated markers characteristic of M2 macrophages such as CD163 and CD206...

Mucinous tubular and spindle cell carcinoma (MTSCC) is a relatively rare renal epithelial neoplasm. Although MTSCC is considered to be a low-grade and indolent neoplasm, aggressive cases have been recently reported. The present study discussed two additional cases of high-grade MTSCC causing multiple distant metastases with a fatal course. In case 1, a 71-year-old patient presented with hematuria and pyuria. Computed tomography (CT) scan of the right kidney revealed a mass lesion, for which partial nephrectomy was performed...

Unexpandable lung is a common complication of malignant pleural effusions and inflammatory pleural diseases, such as pleural infection (e.g. empyema and complicated parapneumonic effusion) and noninfectious fibrinous pleuritis. Unexpandable lung due to pleural disease may be because of an active pleural process, and is referred to as malignant or inflammatory lung entrapment. An unexpandable lung may also be encountered in the setting of remote pleural inflammation resulting in a mature fibrous membrane overlying the visceral pleura preventing full expansion of the lung...

Eren Erken, Ertugrul Erken
Familial Mediterranean fever (FMF) is an autoinflammatory disease manifested by inflammatory attacks of peritonitis, pleuritis, pericarditis accompanied by fever and arthritis. Mutations of MEFV gene results in pyrin dysfunction, which causes uncontrolled interleukin-1 beta production and triggers the inflammatory attacks. Inflammation persists even during attack-free periods in one-third of the FMF patients. Findings of elevated proinflammatory cytokine patterns during remission as well as inflammatory attacks indicate the continuous subclinical disease activity and inflammation...

Adenosine deaminase (ADA) is currently used as a diagnostic marker for tuberculous pleuritis. Although ADA has been suggested as a potential marker for several types of cancer, the importance of each of ADA isoforms as well as their levels and enzymatic activities in tumors need to be further investigated. Herein we developed avian immunoglobulin Y highly specific to human ADA via hens immunization with calf adenosine deaminase. The obtained antibodies were used for the development of a sensitive double-egg yolk immunoglobulin (IgY) sandwich ELISA assay with an ADA detection limit of 0...

BACKGROUND AND OBJECTIVE: Pleuroscopy is the test of choice for patients with suspected malignant pleural effusion and negative cytology. Biopsies negative for malignancy are frequently attributed to non-specific pleuritis, which poses a dilemma in patients with a known active malignancy, raising concern for a false-negative result. Our primary objective was to determine the outcomes of patients with active malignancy who had a non-malignant diagnosis on pleuroscopy. METHODS: Retrospective review of all pleuroscopy cases from January 2005 to January 2015 at our institution was conducted...

Co-infection with cryptococcus and tuberculosis has rarely been reported. We herein report a case of an 80-year-old man with cryptococcal pleuritis concurrent with pulmonary tuberculosis. He was admitted for progression of left pleural effusion and consolidation in the left upper lobe. Culture for Mycobacterium tuberculosis was positive in sputum, and analyses of pleural effusion revealed lymphocyte-predominant high levels of adenosine deaminase (ADA). Medical thoracoscopy revealed massive infiltration of Cryptococcus neoformans in pleura without granuloma...

Malignant mesotheliomas are rare and aggressive tumours arising from mesothelial cells of the pleura and peritoneum. Infrequent sites of origin are the pericardium and tunica vaginalis testis. More than 80% of mesotheliomas are localized in the pleura. Men are more frequently affected than women. The median age is >60 years. Asbestos exposure is the best known aetilogical risk factor and is reported in 54-90% of patients. In Germany, malignant mesotheliomas caused by occupational asbestos exposure are compensated as occupational disease since 1977...

INTRODUCTION: Although pleural effusion (PE) can be caused by several pathologies like congestive heart failure, infections, malignancies, and pulmonary embolism, it is also a common finding in chronic kidney disease (CKD). Diagnostic thoracentesis is of limited value in the differential diagnosis, and the role of more invasive investigations like medical thoracoscopy (MT) is still unclear. AIM: To evaluate the usefulness of MT in unexplained PE in CKD. MATERIALS AND METHODS: In the electronic database of our Institution, we retrospectively searched for patients with CKD who underwent MT for unexplained PE between January 2008 and August 2016...

BACKGROUND: Many centers performing medical thoracoscopy (MT) to diagnose pleural disease will insert a chest tube and admit patients to hospital after the procedure, which is inconvenient for patients and contributes to healthcare costs. We report the data on the safety, outcomes, and performance characteristics of outpatient MT with indwelling pleural catheter (IPC) insertion in a large Canadian cohort. METHODS: This retrospective cohort study reviewed patients who underwent outpatient MT and IPC insertion under conscious sedation...
