Envenoming syndrome is a systemic reaction induced by inoculation of large volumes of Hymenoptera venom. The clinical manifestations range from skin allergic reactions to multiple organ failure. Vespid venom-induced toxic reactions and anaphylaxis are the most common lethal mechanism of death, involving acute respiratory failure, acute liver failure, rhabdomyolysis, acute kidney injury, and severe coagulopathy. Multiple organ failure as a consequence of severe venom toxicity is a rare but dangerous complication in victims. Delay of intervention to correct vespid venom-induced toxic reactions may cause catastrophic complications. Here, we describe a case presenting a rare vespid venom-induced multiple organ failure with systemic coagulopathy after massive Vespa attack.
Transparent conductive thin-films of aluminum-doped zinc oxide (AZO) were deposited on STN-glass substrates by an asymmetric bipolar pulsed DC (ABPDC) reactive magnetron sputtering system. Two different alloys, Zn-1.6 wt% Al and Zn-3.0 wt% Al, were used as the sputtering targets. The films consist of columnar grains with a preferred orientation of c-axis. Strong crystal distortion and high density stacking faults were observed in high resolution TEM micrographs. The full-width at half-maximum (FWHM) of the (002) rocking curve has a close relationship with the resistivity of the films; the smaller the FWHM, the lower the resistivity. The lowest resistivity of 7.0 x 10(-4) omega-cm was obtained from the film deposited with Zn-1.6 wt% Al target at 200 degrees C.
Early surgical intervention in hip fractures is associated with lower complications. This study aimed to determine the appropriate operation time among Asian geriatric patients. The data of 1118 elderly patients with hip fracture at Mackay Memorial Hospital from 1 January 2011, to 31 July 2019, were retrospectively examined. Association between operation waiting time and the occurrence of complications was calculated using a cubic spline model. Significantly increased incidence of pneumonia, myocardial infarction, and heart failure was observed in 30 and 90 days when the patient’s surgical waiting time exceeded 36 h. The incidence rates of pneumonia across the early and delayed groups within 30 and 90 days were 4.4% vs. 7.9%, and 6.2% vs. 10.7%, those of myocardial infarction were 3.0% vs. 7.2%, and 5.7% vs. 9.3%, and those of heart failure were 15.2% vs. 26.8%, and 16.2% vs. 28.5%. Deep vein thrombosis and pulmonary embolism were not associated with surgical delay. The overall 30-day mortality rate was 5.4%, and no significant difference was observed when the surgical waiting time exceeded 36 h. In summary, operation waiting time exceeding 36-h was associated with increased rates of pneumonia, myocardial infarction, and heart failure in Asian geriatric patients undergoing hip fracture surgery.
Approximately 15%-19% of patients with severe acute respiratory syndrome coronavirus type 2 (SARS-CoV-2) infections develop gastrointestinal symptoms. Acute pancreatitis (AP) has been reported in 0.1% of patients with coronavirus disease 2019 (COVID-19). Biliary AP was most common (78.4%) before the COVID-19 pandemic; idiopathic AP is most common in patients with COVID-19 (up to 57.1%). The number of emergency department presentations decreased by 23.3% during the pandemic and many governments made national recommendations to delay nonurgent endoscopic procedures, leading to decrements of 22% in combined esophagogastroduodenoscopy (EGD) and colonoscopy and 20% in EGD after the COVID-19 pandemic. The symptoms and signs of COVID-19-related AP are fever (63%), abdominal pain (58%), respiratory symptoms (40%), nausea and vomiting (39%), and headache (4%). Approximately 5-10% of patients develop necrotizing or hemorrhagic AP, and patients who required surgical intervention had a higher mortality risk. Compared to 2019, the rates of elective surgery decreased by 41.8% in 2020; including cholecystectomy (40.1% decrease) and pancreas (111.1% decrease). Surgical volumes also decreased by 18.7% in 2020; device-assisted laparoscopic and robot-assisted procedures reduced by 45.4% and 61.9% during the COVID-19 Lockdown in 2020.
Myelolipomas are rare benign tumors comprised of mature adipose tissue and hematopoietic elements. Adrenal myelolipomas associated with traumatic adrenal injury are relatively rare and less common on the left due to the limited size and well-protected position of the gland. A 59-year-old female admitted to the emergency department with intermittent left flank pain radiating to the left abdomen after falling from the bed six hours earlier. Her vital signs were stable, and she had tenderness over the left flank area and left abdomen. Her initial hemoglobin level was 12.9 g/dL. Bedside focused assessment with sonography for trauma revealed unclear left kidney margins. Contrast abdominal computed tomography (CT) revealed a space-occupying mass, 11.6×10.4×8.8 cm in dimension, in the left suprarenal region with active bleeding in the lower pole. Angiography did not reveal any active contrast medium extravasation. The CT-guided biopsy, was well performed concomitantly with angiography. Pathological assessment of the biopsy specimen revealed the presence of mostly adipose tissue with few erythrocytes and leukocytes. She was diagnosed with adrenal myelolipoma and admitted to the urology ward for left adrenalectomy with tumor resection. Traumatic adrenal injury, an unusual presentation of adrenal myelolipoma incidentally found in less than 5% of all abdominal blunt injuries, should be considered in cases of bleeding with trauma to the flank for prompt treatment.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
