Porcine teschovirus (PTV) is a devastating virus that targets the central nervous system and led to great economic losses in Europe between the 1920s and 1960s. Since 1973, PTV variants with lower pathogenicity have been prevalent globally, whereas highly pathogenic PTV strains have rarely emerged. In 2022, diarrhea with high mortality occurred on a pig farm in Gansu China.

While the pulmonary effects of regular waterpipe smoking (R-WPS) are well-defined, the impact of occasional waterpipe smoking (O-WPS) on the lungs remains less established. This study investigated the pulmonary toxicity and underlying mechanisms of O-WPS versus R-WPS following 6 months of exposure, focusing on histopathology, inflammation in the lung, bronchoalveolar lavage fluid (BALF), and plasma, as well as oxidative stress, genotoxicity, mitochondrial dysfunction, and the expression of mitogen-activated protein kinases (MAPKs) in lung homogenates. Exposure to both O-WPS and R-WPS resulted in significant histological changes, including increased numbers of alveolar macrophages and lymphocytes, as well as interstitial fibrosis.

Unlabelled: Sarcoidosis is a multisystemic syndrome characterized by non-caseous granulomatous inflammation, although necrotizing sarcoid granulomatosis is considered part of the spectrum of the disease. Drug induced sarcoidosis-like reaction (DISR) is a systemic granulomatous reaction, which is histopathologically identical to primary sarcoidosis - mostly described after the use of biologics like tumour necrosis factor alpha antagonists but also anti-CD20 (rituximab). The authors present the very rare case of a woman with a primary Sjögren's syndrome (pSS) started on rituximab for disease control, which evolved with a 3-year indolent progressive systemic sarcoid reaction.

A 47-year-old woman with a 12-year history of anemia and high C-reactive protein (CRP) levels was admitted to our hospital with worsening fatigue and night sweats. She had high levels of immunoglobulin G (IgG; 4182 mg/dL), IgA (630.6 mg/dL), and CRP (7.

Interstitial lung diseases (ILDs) are pathologies affecting the pulmonary interstitium and, less frequently, the alveolar and vascular epithelia. Bronchoalveolar lavage (BAL) is commonly used in ILD evaluation since it allows the sampling of the lower respiratory tract. The prognostic value of BAL cell counts in ILD is unknown.
