We investigated online newspapers published from 21 January 2020 20 March 2020, reviewed academic medical articles related COVID-19. Additionally, acquired data on...
Numerous statistical models have been developed to accurately predict outcomes in multiple trauma patients. However, such scoring systems reflect the patient's physiological condition, which can only be determined a limited extent, and are difficult use when performing rapid initial assessment. We studied predictive ability of systemic inflammatory response syndrome (SIRS) score compared other systems.We retrospectively reviewed 229 patients with combined chest injury from January 2006 June...
Background: Current international guidelines recommend against deep sedation as it is associated with worse outcomes in the intensive care unit (ICU).However, Korea prevalence of and its impact on patients ICU are not well known.Methods: From April 2020 to July 2021, a multicenter, prospective, longitudinal, noninterventional cohort study was performed 20 Korean ICUs.Sedation depth extent divided into light using mean Richmond Agitation-Sedation Scale value within first 48 hours.Propensity...

Using techniques from theory Lie groups and algebras, equations motion rigid multibody system can be formulated in such way both first second derivatives dynamic with respect to arbitrary joint variables computed analytically. result is one formulate exact gradient Hessian an objective function involving dynamics, develop efficient second-order generating optimal motions....
A Case ReportNative coronary artery spasm after bypass grafting (CABG) is scarce.It frequently causes disastrous circulatory collapse.We report a 72-yr-old male, who experienced native and grafted following CABG, which was successfully treated with angiography intracoronary injection of nitroglycerine.
Indication for extracorporeal membrane oxygenation (ECMO) has been extended as the experience of ECMO in various clinical settings accumulates and outcome after installation improves. We report two cases successful mitral valve surgery severe ischemic regurgitation patients on support cardiogenic shock which developed upon coronary angiography.
Rationale: Massive retropharyngeal hematoma secondary to a minor blunt trauma is rare and easy be missed in emergency settings due the absence of visible tissue injury, especially young patients. However, missing this pathology dangerous can result airway obstruction even death. Therefore, an effective diagnostic strategy must developed thoroughly performed minimize hematoma. Patient concerns: A 49-year-old man with brief cervical hyperextension collision presented mild respiratory...
BackgroundThe COVID-19 pandemic has caused an epidemic of critical patients, some whom have been treated with extracorporeal membrane oxygenation (ECMO). This purpose study is to describe the clinical course patients ECMO.MethodsA multicentered at six hospitals in Daegu was conducted between January and April 2020.ResultsAmong 80 receiving mechanical ventilation support, 19 (24%) were ECMO included (median age 63.0 years). Eight (42%) weaned off (9.8 days, IQR 7.0-13.7). Among them, four...
Surgical repair of the tetralogy Fallot is one most successful operations in treatment congenital heart diseases. We report case a 65-year-old man who had an aortic valve replacement at time complete age forty-three. He subsequently progressive root and ascending aorta dilation to 9 cm. The was done using composite valve-graft performed along with other procedures. Thus, meticulous follow-up after corrective surgery for recommended following initial curative surgery.
Patent ductus arteriosus (PDA) ligation by open surgery is more difficult and dangerous in elderly patients than infants. Nowadays, simple safe interventional catheterization technology used for the closure of uncomplicated isolated PDAs. Therefore, an alternative less invasive therapeutic option must be developed to treat complicated PDA.A 53-year-old woman presented with gradually exacerbated dyspnea on effort continuous cardiac murmurs.Transthoracic echocardiography (TTE)...
A 51-year-old woman visited our hospital with massive hemoptysis. She had suffered from recurrent hemoptysis for five years and undergone bronchial artery embolization many times. The patient a history of pulmonary tuberculosis bronchiectasis. Chest radiography showed consolidation around the nodule in lateral basal segment right lower lobe. We successfully performed lobectomy. histological study resected specimen vegetable foreign body clumps Actinomyces, indicating actinomycosis, which was...
Myositis ossificans (MO) can compress peripheral nerves and cause neuropathy. We herein describe a patient with ulnar neuropathy caused by MO at the medial elbow. A 28-year-old man drowsy mentality multiple organ damage following traffic accident was admitted to our hospital. After 3 weeks of postoperative care, patient’s mental status recovered. However, he complained severe sharp pain in his left forearm fourth fifth fingers. He exhibited weak finger abduction wrist adduction. Severe elbow...
Empyema is the collection of purulent exudate within pleural space. Overall, 36%-65% patients with empyema cannot be treated by medical therapy alone and require surgery. Multiloculated particularly difficult to treat percutaneous drainage. Therefore, we describe our experiences early aggressive surgical treatment for rapid progressive multiloculated empyema.From January 2001 October 2015, retrospectively reviewed 149 diagnosed who received The were divided into 2 groups according whether...
A 16-year-old girl was transferred to the department of thoracic and cardiovascular surgery because a spontaneous pneumothorax with prolonged air leakage. Chest computed tomography demonstrated cystic lesion measuring 2×3 cm involving left upper lobe. Left lobectomy performed via video-assisted thoracoscopic surgery. pathologic examination specimen revealed mesenchymal hamartoma. Despite rarity pulmonary hamartoma, it should be considered potential cause for patients large cyst. Further,...
We study the no global symmetry conjecture in quantum gravity by modeling black holes as non-isometric codes, encoding interior states with charges into fundamental states. The fluctuation of inner products charged can be larger compared to case without charges. map causes different have non-zero overlaps, signaling violation. Renyi entropies radiation are found consistent extremal surface formula. compute version relative entropy, a quantity used measure degree violation Hawking radiation,...
Abstract Rationale: Supradiaphragmatic inferior vena cava (IVC) injury due to blunt thoracic trauma is extremely rare. Budd-Chiari syndrome (BCS) also rare and presents with ascites, abdominal pain, hepatomegaly, leg swelling, jaundice. Its etiology diverse, it rarely caused by trauma. Patient concerns: A 36-year-old man from a traffic accident presented chest pain. Chest computed (CT) emergency surgery CPB revealed completely transected supradiaphragmatic (IVC), which reconstruction was...
