Review Case Reports
An Unusual Case of Explosive Pleuritis without Mediastinal Shift.
Explosive pleuritis (EP) is an under-reported condition. Although there is no agreed-upon definition, generally, the term EP denotes a dramatic clinical and radiologic progression of pleural space inflammation in the setting of pneumonia. The pleural space inflammation leads to the formation of loculated complex pleural effusion or empyema, and pleural adhesion within a matter of hours, typically in less than 24 hours. ⋯ Streptococcal pneumonia is the most common cause of EP. Here we present a case and discuss the clinical, microbiologic, radiologic, and treatment aspects of EP. We also scrutinize the medical literature to compare the previously reported cases.

Psoriasis is a common chronic inflammatory skin disease associated with an increased risk for acute infections. Because chronic kidney disease is a risk factor for pneumonia, end-stage renal disease (ESRD) patients with psoriasis may have an increased risk for acquiring pneumonia. ⋯ When controlling for multiple factors, psoriasis does not increase the risk for pneumonia in ESRD patients. In this cohort, other factors, such as the CCI and tobacco use, were more strongly associated with increased risk for pneumonia than psoriasis.

Background Acute upper gastrointestinal (GIT) bleeding is a common medical emergency clinically manifested by hematemesis and/or melena. This study aimed to elucidate the roles of Helicobacter pylori and the platelet-spleen ratio as risk factors for variceal bleeding in patients with portal hypertension secondary to liver cirrhosis. Methods The study was conducted on 200 patients with liver cirrhosis of various etiologies who were divided into two groups: group 1 included 100 patients with liver cirrhosis and portal hypertension with or without a history of upper GIT bleeding, and group 2 included 100 patients with liver cirrhosis without portal hypertension. ⋯ The calculated odds ratio for the rapid urease test was low (0.851), whereas the calculated odds ratio for the platelet-spleen diameter ratio was higher (9.766) than that for the rapid urease test. Thus, the rapid urease test plays a significantly higher role than the platelet-spleen ratio as a risk factor for bleeding (p-value = 0.001). Conclusions H. pylori has a more significant relationship with upper GIT bleeding than the platelet-spleen diameter ratio.

Extensive studies have revealed that long non-coding RNAs (lncRNAs) are associated with sepsis-induced acute lung injury (ALI). This study focused on the function and potential mechanisms of lncRNA zinc finger antisense 1 (ZFAS1) in a cell model of sepsis-induced ALI. ⋯ Down-regulation of lncRNA ZFAS1 attenuated LPS-induced ALI in HSAECs by regulating the miR-96-5p/OXSR1 axis.
