Periampullary diverticulum is commonly found during endoscopy and can occur at any age although its prevalence increases with age. Periampullary diverticular bleeding is a rare and difficult to diagnose during clinical practice because of its unique appearance and location. This often can lead to massive bleeding and interfere with adequate bleeding control. Endoscopic management on duodenal diverticular bleeding is limited compared to colonic diverticular bleeding due to lack of experience. Herein, we report a case of active bleeding from a periampullary diverticulum during bile duct stone extraction diagnosed by side-viewing endoscope and successfully controlled using hemoclips without any complications.

When epithelial cells are exposed to potentially threatening external stimuli such as allergens, bacteria, viruses, and helminths, they instantly produce “alarmin” cytokines, namely, IL-33, IL-25, and TSLP. These alarmins alert the immune system about these threats, thereby mobilizing host immune defense mechanisms. Specifically, the alarmins strongly stimulate type-2 immune cells, including eosinophils, mast cells, dendritic cells, type-2 helper T cells, and type-2 innate lymphoid cells. Given that the alarm-raising role of IL-33, IL-25, and TSLP was first detected in allergic and infectious diseases, most studies on alarmins focus on their role in these diseases. However, recent studies suggest that alarmins also have a broad range of effector functions in other pathological conditions, including psoriasis, multiple sclerosis, and cancer. Therefore, this review provides an update on the epitheliumderived cytokines in both allergic and non-allergic diseases. We also review the progress of clinical trials on biological agents that target the alarmins and discuss the therapeutic potential of these agents in non-allergic diseases.

Aspergillus causes a variety of clinical syndromes in the lung including tracheobronchial aspergillosis, invasive aspergillosis, chronic necrotizing pulmonary aspergillosis, allergic bronchopulmonary aspergillosis, and aspergilloma. Aspergilloma usually results from ingrowths of colonized Aspergillus in damaged bronchial tree, pulmonary cyst or cavities of patients with underlying lung diseases. There are a few reports on endobronchial aspergilloma without underlying pulmonary lesion. We have experienced a case of endobronchial aspergilloma associated with foreign body developed in an immunocompetent patient without underlying lung diseases. A 59-year-old man is being hospitalized with recurring hemoptysis for 5 months. X-ray and computed tomography scans of chest showed a nodular opacity in superior segment of left lower lobe. Fiberoptic bronchoscopy revealed an irregular, mass-like, brownish material which totally obstructed the sub-segmental bronchus and a foreign body in superior segmental bronchus of the lower left lobe. Histopathologic examinations of biopsy specimen revealed fungal hyphae, characteristic of Aspergillus species.

A 76-year-old man with no notable medical history was scheduled for a robot-assisted radical prostatectomy. After the operation, he was given sugammadex. Two minutes later, ventricular premature contraction bigeminy began, followed by cardiac arrest. Cardiac arrest occurred three times and cardiopulmonary resuscitation was done. The patient recovered after the third cardiopulmonary resuscitation and was transferred to the intensive care unit. Coronary angiography was done on postoperative day 1. The patient was diagnosed with variant angina and discharged uneventfully on postoperative day 8.

Gastric volvulus is a rotation of the stomach of at least 180 associated with a closed loop obstruction. Pare described the first case of gastric volvulus m 1579. Laxity of the gastric ligament, a congenital or acquired diaphragmatic defect, increased abdominal pressure, and a genetic component contributing to gastric volvulus. Gastric volvulus has been classified clinically as acute and chronic gastric volvulus, and can be classified anatomically as organoaxial, mesenteroaxial or a mixed type. Gastric volvulus occurs in children usually before 1 year of age or elderly patients. In acute gastric volvulus, and be patients complain of sudden abdominal or chest pain. The chest pain, which can radiate to the arms and neck accompanied by dyspnea, may initially lead to consideration of ischemic heart disease. Chronic gastric volvulus is difficult to diagnose because it may be associated with mild and nonspecific symptoms such as epigastric discomfort, fullness or heartburn. We experienced a case of 83 year old male with an organoaxial type of chronic gastric volvulus, iagnosed by upper gastrointestinal series, and treated with conservative rnanagement.

Purpose:
Thrombocytopenia (platelet count <150×103 /μL) is associated with poor outcomes in various critical illness settings. However, the prognostic value of platelet count in patients with cardiogenic shock (CS) remains unclear.
Materials and Methods:
We enrolled 1202 patients between January 2014 and December 2018 from a multicenter retrospective– prospective cohort registry of CS. Clinical characteristics and treatment outcomes were compared between the patients with and without thrombocytopenia.
Results:
At presentation with CS, 244 (20.3%) patients had thrombocytopenia. The patients with thrombocytopenia had lower blood pressure, hemoglobin level, and worse liver and renal functions compared to the patients without. During hospitalization, the patients with thrombocytopenia had more frequent gastrointestinal bleeding (10.5% vs. 3.8%, p=0.009), sepsis (8.3% vs. 2.6%, p=0.013), requirement of renal replacement therapy (36.5% vs. 18.9%, p<0.001), requirement of mechanical ventilation (65.2% vs.54.4%, p=0.003), longer intensive care unit stay (8 days vs. 4 days, p<0.001), and thirty-day mortality (40.2% vs. 28.5%, p<0.001) compared to those without. In addition, the platelet count was an independent predictor of 30-day mortality (per 103 /µL decrease; adjusted hazard ratio: 1.002, 95% confidence interval: 1.000–1.003, p=0.021).
Conclusion
Thrombocytopenia at CS presentation was associated with worse clinical findings, higher frequencies of complications, and longer stay at the intensive care unit. Also, thrombocytopenia was independently associated with increased 30-day mortality.(Clinical trial registration No. NCT02985008).

Coronavirus disease 2019 (COVID-19) outbreak is spreading rapidly all over the world, being a major threat to public health. Since clinical feature of COVID-19 has not been fully evaluated yet, empirical antibacterial agents are frequently combined for the treatment of COVID-19 in addition to antiviral agents, concerning co-existing bacterial pathogens. We experienced a case of severe thrombocytopenia with epistaxis and petechiae, while treating a COVID-19 patient with ceftriaxone, levofloxacin, and lopinavir/ritonavir. The platelet count decreased to 2,000/mm 3 and recovered after discontinuation of the three suspected drugs. In treating a potentially fatal emerging infectious disease, empirical and/or experimental approach would be unavoidable. However, the present case suggests that the possibility of adverse effects caused by polypharmacy should also be carefully considered.
