A Rare Case of Gastric Phytobezoar (Diospyrobezoar) in a Healthy Adult.

Phytobezoars are solid masses of indigestible plant material and are a common type of gastrointestinal bezoar, with varying incidences globally. These bezoars typically form from the ingestion of high-fiber fruits and vegetables and are associated with factors such as decreased gastric acid production and delayed gastric emptying. We present a case of a 35-year-old healthy man with recurrent upper abdominal pain, nausea, a rolling ball sensation in the abdominal region, and a history of consuming unripe persimmons.

Disseminated Extrapulmonary Tuberculosis in an Immunocompetent Individual Without Pulmonary Involvement: A Case Report.

Tuberculosis (TB) is a major global health burden, particularly in developing countries like India. While the most common presentation is pulmonary TB, extrapulmonary TB involving other body systems can also occur, posing diagnostic challenges. We present the case of a 24-year-old immunocompetent man from India who exhibited an uncommon and complex presentation of disseminated extrapulmonary TB.

Electrochemical Behavior of SiC-Coated AA2014 Alloy through Plasma Electrolytic Oxidation.

In this study, the corrosion performance of AA2014 aluminum alloy was enhanced by coating the alloy with a layer containing silica (SiC) that was formed by the plasma electrolytic oxidation (PEO) process. The PEO process was performed with different electrical parameters (frequency, current mode, and duty ratio) and both with and without SiC to investigate the microstructural and electrochemical differences in the coated samples produced from the process. The microstructure and composition of the PEO coatings were studied using X-ray diffraction (XRD) and scanning electron microscopy (SEM) with energy dispersive spectroscopy (EDS).

Investigation of flux stability and fouling mechanism during simultaneous treatment of different produced water streams using forward osmosis and membrane distillation.

Forward osmosis-membrane distillation (FO-MD) hybrids were recently found suitable for produced water treatment. Exclusion of synthetic chemical draw solutions, typically used for FO, can reduce FO-MD operational costs and ease its onsite application. This study experimentally validates a novel concept for the simultaneous treatment of different produced water streams available at the same industrial site using an FO-MD hybrid system.

Survey of flexible bronchoscopy practice in adults in Saudi Arabia.

To assess current adherence to international guidelines for practitioners of bronchoscopy in the Kingdom of Saudi Arabia. Methods: A cross-sectional survey was conducted in Saudi Arabia between December 2016 and March 2017. Pulmonologists, thoracic surgeons, and intensivists were invited to answer an emailed self-administered questionnaire survey seeking information on how they performed flexible bronchoscopy in adults.
