Tracheal stenosis due to cervicothoracic hyperlordosis in patients with cerebral palsy treated with posterior spinal fusion: a report of the first two cases.

BMC Musculoskelet Disord 2021 Feb 23;22(1):217. Epub 2021 Feb 23.

Department of Orthopaedic Surgery, The University of Tokyo Hospital, 7-3-1 Hongo, Bunkyo-ku, 113-8655, Tokyo, Japan.

Background: Spinal deformity is frequently identified in patients with cerebral palsy (CP). As it progresses, tracheal stenosis often develops due to compression between the innominate artery and anteriorly deviated vertebrae at the apex of the cervicothoracic hyperlordosis. However, the treatment strategy for tracheal stenosis complicated by spinal deformity in patients with CP remains unknown. Read More

Esophageal Obstruction and Death in a Nonverbal Patient.

J Emerg Med 2021 May 12;60(5):e109-e113. Epub 2021 Feb 12.

Department of Emergency Medicine, Cleveland Clinic Akron General, Akron, Ohio; Northeast Ohio Medical University, Rootstown, Ohio.

Background: There are more than 100,000 cases of esophageal foreign body in the United States each year. Most cases resolve spontaneously; however, complete esophageal obstruction is a medical emergency. Patients with developmental disabilities are at high risk, because a large percentage of this population is effected by dysphagia, pica, tooth loss, or impulsive swallowing. Read More

Intravital Imaging of Pulmonary Immune Response in Inflammation and Infection.

Front Cell Dev Biol 2020 15;8:620471. Epub 2021 Jan 15.

Department of Physiology & Biophysics, Dalhousie University, Halifax, NS, Canada.

Intravital microscopy (IVM) is a unique imaging method providing insights in cellular functions and interactions in real-time, without the need for tissue extraction from the body. IVM of the lungs has specific challenges such as restricted organ accessibility, respiratory movements, and limited penetration depth. Various surgical approaches and microscopic setups have been adapted in order to overcome these challenges. Read More

Case report of tracheobronchial injuries after acid ingestion: CT findings with serial follow-up: Airway complication after acid ingestion.

Medicine (Baltimore) 2020 Dec;99(50):e23586

Division of Pulmonary and Critical Care Medicine, Department of Internal Medicine, Kyung Hee University Hospital at Gangdong, Seoul, Republic of Korea.

Rationale: Tracheobronchial injury from acid ingestion is a less reported clinical presentation than injury of the gastrointestinal tract, but it can occur due to direct exposure from acid aspiration and cause fatal complications.

Patient Concerns: A 43-year-old man presented to the emergency department after ingesting nitric acid complaining of chest pain and dyspnea.

Diagnosis and Management of Acute Respiratory Distress Syndrome in a Time of COVID-19.

Diagnostics (Basel) 2020 Dec 6;10(12). Epub 2020 Dec 6.

Department of Medicine, Schulich Faculty of Medicine and Dentistry, Western University, London, ON N6A 5W9, Canada.

Acute respiratory distress syndrome (ARDS) remains a serious illness with significant morbidity and mortality, characterized by hypoxemic respiratory failure most commonly due to pneumonia, sepsis, and aspiration. Early and accurate diagnosis of ARDS depends upon clinical suspicion and chest imaging. Coronavirus disease 2019 (COVID-19) is an important novel cause of ARDS with a distinct time course, imaging and laboratory features from the time of SARS-CoV-2 infection to hypoxemic respiratory failure, which may allow diagnosis and management prior to or at earlier stages of ARDS.

Clinical features of patients with hepatic portal venous gas.

BMC Surg 2020 Nov 27;20(1):300. Epub 2020 Nov 27.

Department of Surgery, Ome Municipal General Hospital, 4-16-5, Higashi Ome, Ome-shi, Tokyo, 198-0042, Japan.

COVID-19 pneumonia: the great radiological mimicker.

Insights Imaging 2020 Nov 23;11(1):118. Epub 2020 Nov 23.

Department of Radiology, School of Medicine, Tıp Fakültesi Hastanesi, Hacettepe University, 06100, Sıhhiye, Ankara, Turkey.

Coronavirus disease 2019 (COVID-19), caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), has rapidly spread worldwide since December 2019. Although the reference diagnostic test is a real-time reverse transcription-polymerase chain reaction (RT-PCR), chest-computed tomography (CT) has been frequently used in diagnosis because of the low sensitivity rates of RT-PCR. CT findings of COVID-19 are well described in the literature and include predominantly peripheral, bilateral ground-glass opacities (GGOs), combination of GGOs with consolidations, and/or septal thickening creating a "crazy-paving" pattern.

Risk factors for aspiration pneumonia in patients with dysphagia undergoing videofluoroscopic swallowing studies: A retrospective cohort study.

Medicine (Baltimore) 2020 Nov;99(46):e23177

Department of Rehabilitation Medicine, Nowon Eulji Medical Center, Eulji University, Seoul, Republic of Korea.

Prediction of aspiration pneumonia development in at-risk patients is vital for implementation of appropriate interventions to reduce morbidity and mortality. Unfortunately, studies utilizing a comprehensive approach to risk assessment are still lacking. The objective of this study was to analyze the clinical features and videofluoroscopic swallowing study (VFSS) findings that predict aspiration pneumonia in patients with suspected dysphagia.

Primary cardiac hemangiosarcoma in a horse: echocardiographic and necropsy findings.

J Vet Cardiol 2020 Dec 8;32:66-72. Epub 2020 Oct 8.

Department of Clinical Sciences, Cummings School of Veterinary Medicine at Tufts University, 200 Westboro Road, North Grafton, MA, 01536, USA. Electronic address:

Cardiac hemangiosarcoma, especially primary, is infrequently reported in the horse and remains a diagnostic challenge because of vague clinical signs and difficulty to reach an antemortem diagnosis. A 17-year-old American Quarter Horse gelding was presented with a history of tongue swelling and secondary aspiration pneumonia. Initial assessment indicated dehydration, and thoracic ultrasound revealed an abnormal structure within the myocardium alongside the previously suspected aspiration pneumonia. Read More

Karen Boretsky

Children (Basel) 2020 Nov 6;7(11). Epub 2020 Nov 6.

Department of Anesthesiology, Critical Care and Pain Medicine, Boston Children's Hospital, Harvard Medical School, Boston, MA 02115, USA.

Anesthesiologists and other acute care physicians perform and interpret portable ultrasonography-point-of-care ultrasound (POCUS)-at a child's bedside, in the perioperative period. In addition to the established procedural use for central line and nerve block placement, POCUS is being used to guide critical clinical decisions in real-time. Diagnostic point-of-care applications most relevant to the pediatric anesthesiologist include lung ultrasound for assessment of endotracheal tube size and position, pneumothorax, pleural effusion, pneumonia, and atelectasis; cardiac ultrasound for global cardiac function and hydration status, and gastric ultrasound for aspiration risk stratification.
