RESUMO
Pulmonary embolism (PE) is the obstruction of the pulmonary artery or its branches, usually by a thrombus that originates in the lower extremity veins. PE is associated with high mortality risk. Here, we present the case of a patient who initially presented with dysphagia. Chest radiography revealed a lung nodule. Endobronchial ultrasonography (EBUS) was performed to evaluate the nodule, which revealed a pulmonary embolus. Subsequently, CT angiography of the chest was performed to confirm the diagnosis of PE. Anticoagulation therapy was initiated. The biopsy results were positive for lung adenocarcinoma. There are only few reported cases of PE diagnosed using EBUS. Here, the patient had not presented with the signs and symptoms of PE. Had PE not been diagnosed by EBUS, our patient could have potentially had a disastrous outcome. Moreover, this case shows that EBUS may be used for diagnosing PE.

We present a case of new-onset haemoptysis and associated lung lesion on chest imaging in the setting of the COVID-19 pandemic. This was believed to be due to dental care avoidance after tooth fracture and long-term use of temporary dental filler, with subsequent aspiration and bronchial injury. Our patient underwent bronchoscopy due to persistent haemoptysis with findings of mild traumatic injury. She responded to conservative management with no pharmacologic intervention. With time, there was resolution of symptoms and radiographic improvement of the lung lesion. We include a brief discussion on the influence of the COVID-19 pandemic on healthcare avoidance, complications of tooth fracture and the differential diagnosis of a new solitary lung lesion on chest imaging.

Nasogastric tube insertion is a routine procedure that is utilized on a daily basis in our hospitals and long-term care facilities. Blind insertion of these tubes is usually performed by nurses, residents and other health care providers. In this report, we present an incident of misplacement of the nasogastric tube into the bronchial tree causing parenchymal injury and pneumothorax. We also highlight the importance of nasogastric tube placement confirmation and possible pitfalls in interpreting confirmation radiographs.

Yellow nail syndrome (YNS) has traditionally been thought of as a triad of exudative pleural effusion, yellow nails, and lymphedema. More recently, in addition to the hallmark yellowish nail discoloration, the diagnostic criteria required an associated lymphedema and/or chronic respiratory manifestations including pleural effusions, bronchiectasis or chronic sinusitis. Etiology remains unknown and treatment is supportive and directed towards patient's specific complaints. While described alongside multiple endocrine, lymphatic and autoimmune disorders, its most ominous association is malignancy, raising YNS as a possible paraneoplastic condition. Here we present the case of an 80 years-old female with worsening restrictive airway disease and acquired yellow nails, with development of dyspnea, cough and leg edema. Recurrent exudative lymphocyte predominant pleural effusion was treated definitively with pleurodesis. Her leg edema and yellow nails were treated conservatively. We describe previous case reports and series in the literature, outline therapeutic options and discuss prognosis.

Chylothorax is the presence of a chylous effusion in the pleural space. Diagnosing chylothorax requires a high clinical suspicion, awareness of the different appearances of a chylothorax and the performance of tests on the pleural fluid, additional to those typically required to differentiate an exudate from a transudate based on Light's criteria. Chylothorax is a more common diagnosis in the trauma and post-surgical patients, but it is still important for practitioners of other disciplines to be aware of it. In this article we provide a concise summary of chylothorax diagnosis and management.

OBJECTIVES: To evaluate the clinico-radiological findings of acute fibrinous and organizing pneumonia (AFOP) in the literature according to whether a surgical or non-surgical biopsy was performed, as well as to identify prognostic predictors. METHODS: We searched the Embase and OVID-MEDLINE databases to identify studies that presented CT findings of AFOP and had extractable individual patient data. We compared the clinical and CT findings of the patients depending on whether a surgical or non-surgical biopsy was performed and identified survival predictors using a multivariate logistic regression analysis. RESULTS: Eighty-one patients (surgical biopsy, n = 52; non-surgical biopsy, n = 29) from 63 studies were included. The surgical biopsy group frequently experienced an acute fulminant presentation (p = .011) and dyspnea (p = .001) and less frequently had a fever (p = .006) than the non-surgical biopsy group. The surgical biopsy group had a worse prognosis than the non-surgical biopsy group in terms of mechanical ventilation and mortality (both, p = .023). For survival analysis, the patients with the predominant CT finding of patchy or mass-like air-space consolidation survived more frequently (p < .001) than those with other CT findings. For prognostic predictors, subacute indolent presentation (p = .001) and patchy or mass-like air-space consolidation on CT images (p = .002) were independently associated with good survival. CONCLUSIONS: Approximately one-third of alleged AFOP cases in the literature were diagnosed via non-surgical biopsy, but those cases had different symptomatic presentations and prognosis from surgically proven AFOP. Subacute indolent presentation and patchy or mass-like air-space consolidation at the presentation on CT images indicated a good prognosis in patients with AFOP. KEY POINTS: ⢠Acute fibrinous and organizing pneumonia (AFOP) cases diagnosed via non-surgical biopsy had different symptomatic presentations and prognosis from surgically proven AFOP. ⢠Subacute indolent presentation and patchy or mass-like air-space consolidation on CT images indicated a good prognosis in patients with acute fibrinous and organizing pneumonia.

BACKGROUND: We aim to describe the basic demographics, clinical course and outcomes of critically ill patients with Covid-19 admitted to Avera McKennan Hospital and University Health Center Intensive Care Unit (ICU) between March 20 and May 4, 2020. METHODS: In this single centered, retrospective, observational study, we enrolled 37 critically ill adults with COVID-19 pneumonia admitted to the (ICU) between March 20 and May 4, 2020. Demographic data, admitting symptoms, laboratory values, co-morbidities, treatments and clinical outcomes were collected. Data was compared between survivors and non-survivors. We aim to describe our data and report the 28-day mortality as of June 1, 2020. RESULTS: Of 154 patients admitted with COVID-19 pneumonia during our study period, 37 (24 percent) were critically ill and required an ICU stay. The mean age was 58 years and 76 percent were men. Of these 37 patients, 28 (78 percent) had a chronic illness (diabetes in 43 percent, hypertension in 47 percent). In addition, 54 percent were associated with a local meat packing plant. Most common presenting symptoms were dyspnea (92 percent), cough (70 percent) and fever (68 percent). The mean PaO2/ FiO2 ratio was 143 (67-362). Significant lab findings include the following: 54 percent of patients had lymphocytopenia, the mean ferritin was 850 ng/mL (10-3528), the mean D-Dimer was 4.09 FEU ug/mL and the mean IL-6 was 96.5 pg/mL. At 28 days, 24 percent (nine) had died. Twenty-five (68 percent) patients required mechanical ventilation, with 10 (27 percent) of those patients requiring initiation of neuromuscular blocking agents for ventilator compliance. Of those four (40 percent) did not survive. In addition, 20 patients (54 percent) were proned. Pneumomediastinum or pneumothorax occurred in five of the 37 (14 percent). Renal replacement therapy was required in 6 of the 37 patients, 4 of whom (66 percent) died. Steroids were used in 70 percent of patients, tocilizumab in 59 percent, and hydroxychloroquine in 27 percent. All patients received antibiotics. Convalescent plasma became available for our 5th patient. A total of 29 (78 percent) received convalescent plasma, (86 percent of survivors and 56 percent non-survivors). Median ICU length of stay was 11 days for both survivors (1-49) and non-survivors (1-21). There were no differences in age, body mass index (BMI), or initial PaO2/FiO2 (P/F) among those two groups. Non-survivors (nine) included the two immune compromised patients in our cohort, two patients with pre-existing DNR/DNI status, and one death within two hours of admit. Compared with survivors, more of the non-survivors received vasopressors (78 percent vs 46 percent), dialysis (44 percent vs 7 percent) and hydroxychloroquine (44 percent vs 21 percent). The first 5 patients treated in the ICU did not survive. One month after the initial case was reported in South Dakota, our ICU experienced a six-week surge. At its highest, COVID-19-related census reached 63 percent of the ICU capacity (15/24). CONCLUSION: Mortality of critically ill patients with COVID-19 is high. Multi-organ, advanced and prolonged critical care resources are needed. Interpretation of our data is limited by a higher mortality of the earlier members of the cohort, a change in therapeutic practice over time and institution of social distancing.

Vaping has recently gained popularity among teenagers and young adults, well beyond its scope as an alterna- tive to cigarette smoking. A perceived favorable safety profile may have stemmed from the fact that vaping is being evaluated as a smoking cessation tool. We present a case of a young adult non-smoker who was exposed to commercially available vaping, and socially available cannabinoid by vaporizer, one to two weeks prior to developing respiratory and constitutional symptoms. His work-up confirmed a case of vaping induced lung injury.

We present a very rare case of concurrent empyema and liver abscess caused by Fusobacterium. Our patient presented with 3-month history of subtle abdominal discomfort and cough leading to eventually presenting with marked chest pain, dyspnoea and septic shock. CT revealed a liver abscess and large right-sided pleural effusion. Drainage of the pleural effusion yielded gross pus with the growth of Fusobacterium varium, while drainage of the liver abscess yielded Fusobacterium nucleatum The patient responded to drainage and antibiotic therapy with resolution of symptoms and decrease in the size of empyema and abscess on follow-up imaging. We also include a review if literature of related fusobacterial infections.

INTRODUCTION: Small cell lung cancer (SCLC), having properties of neuroendocrine cells, accounts for a small (15 percent) but significant percent of all newly diagnosed lung cancers and is distinguished from non-small cell lung cancer by its rapid doubling time, high growth fraction and the early development of widespread metastases. Therefore, investigation into early diagnosis and treatment is crucial. One sequela of SCLC is a paraneoplastic neurological syndrome usually mediated by a high titer of anti-Hu antibodies, a disease which can present in several variations of paraneoplastic encephalomyelitis. The presence of anti-Hu antibodies in patient serum, even at a low titer, may serve as a diagnostic marker for SCLC and as a model for antibody-based early cancer detection. Furthermore, anti-Hu titers may eventually function as a prognostic indicator and trending titers may be a way to monitor treatment of SCLC and associated paraneoplastic syndromes. METHODS: In this retrospective chart review from a single hospital, we review all patients who had positive anti-Hu antibodies and discuss level of titers at diagnosis, outcomes, and length of survival. RESULTS: We describe three cases of positive anti-Hu antibodies and document their diagnosis of SCLC and outcomes. CONCLUSIONS: Anti-Hu antibodies can be used as a diagnostic tool for aiding in the diagnosis of SCLC. Anti-Hu antibodies may be able to be followed as a marker of progression of the disease.

A 50-year-old man was treated with trimethoprim-sulfamethoxazole (TMP-SMX) for acute arthritis of his right big toe. Within a few days, he developed dyspnoea, hypoxaemia and diffuse pulmonary infiltrates. Symptoms improved with discontinuation of the antibiotic but worsened again with its reintroduction. An open lung biopsy was performed. We describe the workup performed and the factors that pointed to a final diagnosis of TMP-SMX-related pulmonary toxicity in the form of acute fibrinous organising pneumonia.

Diffuse alveolar haemorrhage (DAH) is a clinical syndrome resulting from injury to the alveolar microcirculation, most commonly associated with not only autoimmune disorders or connective tissue disease, but also a variety of infections, neoplasms and toxins. We report here a case of an otherwise healthy young man with DAH attributable to an inhalation injury resulting from use of aerosol spray paint.
