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. Imaging revealed the presence of phytobezoars in the stomach, leading to unsuccessful endoscopic attempts at removal. Laparoscopic extraction was eventually performed successfully after failed conservative management. The case highlights the rarity of diospyrobezoars, a subtype of phytobezoars formed from persimmon ingestion, and the challenges in their management. Surgical intervention, particularly laparoscopic extraction, can be effective but carries risks such as surgical site infections. Comprehensive care involving diagnostic imaging, non-surgical interventions, and surgical techniques is crucial for the successful management of phytobezoars. Phytobezoars, though relatively common, present unique diagnostic and management challenges, especially when formed from specific dietary factors such as persimmons. Understanding their epidemiology, clinical manifestations, and treatment options, including the role of laparoscopic surgery, is essential for optimizing patient outcomes and minimizing complications such as surgical site infections.

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. The patient had an asymptomatic brain cavitated lesion, likely tuberculoma, cervical lymphadenopathy, a small subcutaneous collection in the neck, a destructive lytic lesion in the sacrum, and a subcutaneous collection in the left gluteal/paraspinal region, all in the absence of pulmonary involvement. This combination of manifestations has not been previously reported. The presence of cervical lymphadenopathy and a slowly growing subcutaneous abscess were important clues that guided the diagnostic workup. Maintaining a high index of suspicion for TB, even in atypical presentations and immunocompetent individuals, is crucial, particularly in high-TB-burden regions. This case highlights the importance of considering disseminated extrapulmonary TB in the differential diagnosis, even in the absence of pulmonary involvement and typical risk factors. A high index of suspicion, a multidisciplinary approach, and a comprehensive diagnostic workup are essential for the timely recognition and management of these challenging conditions.

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). A potentiodynamic polarization test and electrochemical impedance spectroscopy (EIS) were used to investigate the electrochemical behavior of the AA2014-PEO-coated samples. The potentiodynamic polarization showed that the SiC-PEO-coated samples had a significantly decreased corrosion rate (99.8%) compared with the uncoated AA2014 Al alloy. Our results showed that the coats containing SiC possessed a much higher corrosion resistance than both the uncoated AA2014 Al alloy (8,344,673%) and the SiC-free coatings, which possess low corrosion resistance, because of their higher chemical stability and more compact microstructure.

Survey of flexible bronchoscopy practice in adults in Saudi Arabia.

OBJECTIVES: 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. The data collected were compared between the 3 specialties. Results: Eighty-two (18%) of 456 invited practitioners completed the survey. Fifty-eight (72%) of the 82 respondents were pulmonologists. Forty (53%) of 76 respondents (93%) who had received bronchoscopy training received it abroad. Twenty-seven respondents (33%) had also received training in endobronchial ultrasound, electrocautery, brachytherapy, stent insertion, and laser procedures. Fifty-eight respondents (70%) preferred patients to undergo fasting for at least 4 hours before the procedure. Lidocaine was used for topical anesthesia, mainly by aerosol spray or nebulization. Midazolam was used by 62%, fentanyl by 50%, and propofol by 12% of respondents. Ninety percent of pulmonologists reported requesting a chest radiograph after transbronchial lung biopsy. Safety procedures for bronchoscopists, for example, wearing masks and eye protection, and for patients, for example, availability of anesthetic reversal agents, were not universally applied. Conclusion: Bronchoscopy is not standardized in Saudi Arabia. National guidelines for the indications and practice of bronchoscopy are required.
