Beware of the Acute Respiratory Distress Syndrome in a Pulmonary Blastomycosis!

Blastomyces dermatitidis is a dimorphic fungus that can range from mild to severe disease presentation, including the acute respiratory distress syndrome (ARDS) based on the individual's immunity. Acute respiratory distress syndrome is an uncommon presentation having an incidence of about 10% to 15% but has a high mortality exceeding 90%. This is a case of a 50-year-old female with past medical history of asthma and type 2 diabetes mellitus who presented to the pulmonology clinic with worsening dyspnea for the last 2 months. She also had a lesion in the left lower back, which was draining purulent fluid. Chest radiographs showed bilateral infiltrates and was started empirically on vancomycin and piperacillin-tazobactam. Bronchoalveolar lavage was done and the cultures grew B dermatitidis. The patient was moved to a higher level of care and given amphotericin B. Unfortunately, the patient experienced septic shock, which later deteriorated into cardiac arrest, ultimately leading to their passing. The importance of early diagnosis of blastomycosis and timely treatment has been emphasized in this case report.

A Decision-oriented Approach to Evaluating a Leadership Curriculum in Fellowship.

Background: Graduate Medical Education (GME) emphasizes the role of the annual program evaluation to identify opportunities, create action plans, and track improvements longitudinally. There is a lack of a systematic approach to the evaluation of educational curricula. Comprehensive curriculum evaluation can inform the educators about specific modifications to achieve high standards, desired outcomes, and the anticipated objectives. Objective: To evaluate a leadership in quality improvement program in a pulmonary/critical care fellowship training program using the context, input, process, product (CIPP) model. The CIPP model, given its focus on evaluating different aspects of a program, provides concrete and targeted feedback to guide improvement decisions. Methods: Evaluation questions addressing the four focused areas were created, pilot tested, and revised. The questions were framed toward optimization of alignment (e.g., program activities with stated objectives, program goals with theoretical perspective, program curriculum with trainee needs) and gaining information about the efficacy of the program in achieving the desired outcomes. To enhance the validity of the results, we triangulated the data-gathering approach by administering surveys and conducting interviews and focus groups by random selection from the eligible participants. Qualitative data were transcribed, coded, and categorized into themes aligning with the four aspects of the CIPP model. Results: We interviewed 9 participants and conducted three focus groups with 20 participants. The surveys provided vital quantitative information that was cross-verified with the qualitative data; 23 of the 25 (92%) participants completed the survey. The results of qualitative thematic analysis were organized in the CIPP format. The context evaluation of the program revealed that the fellows and faculty were unfamiliar with the guiding principles of the course. The input evaluation highlighted the competing interests that hampered the engagement of the fellows during the evening weekly report-outs. The process evaluation revealed clustering of didactic sessions at the start of the course. The product evaluation stressed the difficulty in completing the quality improvement projects in the allotted timeframe. Conclusion: Conducting a robust evaluation of an educational curriculum provides insights into gaps in the various stages of the program. Time and resources needed for conducting evaluation by using the CIPP model should be considered.

Status of COVID-19 Patients Treated With Extracorporeal Membrane Oxygenation in Japan: Nationwide Database Analysis.

Background The report of epidemiological data on coronavirus disease 2019 (COVID-19) patients treated using extracorporeal membrane oxygenation (ECMO) in Japan has been limited. Our study seeks to fill the existing gap in knowledge by providing an in-depth analysis of the clinical epidemiological characteristics and diverse medical outcomes of COVID-19 patients treated with ECMO in Japan. Methods This study used the COVID-19 Registry Japan nationwide database. We included patients aged 18 years or older enrolled between March 17, 2020, and February 1, 2022, with traceable ECMO data. The items on clinical epidemiological characteristics and various medical outcomes were collected. Statistical analysis included a median and interquartile range (IQR) for continuous variables and frequencies for categorical variables. Results The number of participating hospitals was 731, and the number of patients enrolled for analysis was 49,590. Of these, 196 (0.4%) patients received ECMO. Hospital mortality was 33.2%, and discharge to home was 23.0% in the ECMO group. The complications during hospitalization included pneumothorax (9.7%), seizures (4.1%), stroke (4.6%), and pulmonary thromboembolism (2.0%). At discharge, 38.3% had worsened self-care ability, and 38.8% had worsened ambulatory function. Conclusions The results of ECMO treatment in Japan showed that the mortality and complication rates were well-controlled compared with those worldwide.

T-cell Acute Lymphoblastic Leukemia in Crisis: Hyperleukocytosis, Tumor Lysis Syndrome, and Innovative Approaches.

T-cell acute lymphoblastic leukemia (T-ALL) is a rare hematologic malignancy with a unique set of clinical challenges when it occurs in adults. This case report presents the complex management of a 32-year-old male with T-ALL who developed symptomatic hyperleukocytosis and tumor lysis syndrome. Upon presentation, the patient exhibited a constellation of critical clinical and laboratory findings, including leukocytosis, anemia, thrombocytopenia, hyperkalemia, high-anion gap metabolic acidosis, and acute kidney injury. Despite an initial diagnosis of an allergic reaction, the subsequent course of the disease necessitated rapid medical intervention and consultation with multiple specialties, including hematology-oncology and nephrology. The challenges encountered in managing this patient's condition, particularly in an intensive care unit setting, underscored the need for a tailored and multidisciplinary approach. Treatment modalities included leukapheresis, continuous renal replacement therapy, aggressive fluid resuscitation, and chemotherapy. The case highlights the intricate decision-making processes and adaptability required when addressing T-ALL with hyperleukocytosis and tumor lysis syndrome, particularly in cases where conventional chemotherapy is contraindicated. This report underscores the importance of ongoing research and the need for standardized treatment protocols for such complex clinical scenarios.

Risk Factors and Predictors of Prolonged Mechanical Ventilation Following Cardiac Surgery: A Narrative Review.

The subset of patients requiring prolonged mechanical ventilation is significantly high worldwide, making it an important topic of continuous and ongoing research. Over the years, various articles have shown that there may be predictors of prolonged ventilation that could be applied in healthcare to make it more patient-centered. The available literature suggests that authors have different definitions of "prolonged" ventilation. However, most critical care units embrace caution if a patient needs mechanical ventilation for more than 48 to 72 hours. The major benefits of mechanical ventilation are an overall decrease in the work of breathing and the facilitation of relatively easier pumping from an ailing heart. An elevated risk of prolonged ventilation after cardiac surgery exists in patients with higher classes of heart failure (as classified by the New York Heart Association (NYHA) or Canadian Cardiovascular Society (CCS)), a pre-existing congenital or acquired cardiac abnormality, and patients with renal failure, to name a few. The impact on quality of life has also been widely studied; as mortality rates increase with factors like age and days dependent on ventilation. Patients undergoing prolonged ventilation constitute an administrative challenge for critical care units, highlighting how multiple patients in this bracket can overwhelm the healthcare system. The use of prediction models in this context can aid healthcare delivery tremendously. Using different predictors, we can craft tailor-made treatment options and achieve the goal of more ventilator-free days per patient.

When Pain Relief Turns Perilous: Uncovering the Hidden Dangers and Advanced Management of Benzocaine-Induced Methemoglobinemia.

Benzocaine-induced methemoglobinemia is a rare complication associated with benzocaine, a local anesthetic known for its rapid pain relief. Acquired methemoglobinemia occurs when hemoglobin is oxidized to a ferric state, impairing oxygen binding. This condition can lead to respiratory distress and potentially fatal outcomes if not promptly diagnosed and treated. We present the case of a 61-year-old Caucasian female admitted with respiratory distress after lumbar stenosis surgery. She developed acute hypoxemic respiratory failure due to pneumonia. Although initially responsive to antibiotics and oxygen, her condition worsened overnight despite non-invasive bilevel-positive airway pressure (BiPAP) therapy. The use of benzocaine spray for throat pain led to suspected methemoglobinemia. She was treated with high-dose vitamin C and methylene blue, resulting in significant improvement. This case report aims to raise awareness among healthcare workers and emphasizes that timely recognition and management are crucial for better outcomes.

A Rare Presentation of Systemic Lupus Erythematosus (SLE) With Hemoptysis and Hematuria: A Case Report.

Systemic lupus erythematosus (SLE) is an autoimmune disease characterized by type II and type III hypersensitivity reactions that affect multiple organs, including the joints, heart, lungs, brain, skin, and kidneys. Patients with SLE can experience a range of symptoms, ranging from fever and joint pain to a distinctive butterfly facial rash. Severe complications may encompass conditions such as diffuse alveolar hemorrhage (DAH), pulmonary hypertension, and lupus nephritis, among others. Among them, DAH, a critical pulmonary complication in SLE, involves bleeding from interstitial capillaries and alveoli due to immune complex damage. This case report describes a patient who was initially misdiagnosed but later confirmed to have SLE. The patient presented with persistent symptoms, including cough, dyspnea, and fever, over two weeks and subsequently developed hematuria and hemoptysis within the last two days. The progression of symptoms led to an acute exacerbation, resulting in her admission to the emergency department. Subsequent evaluations confirmed the diagnosis of lupus nephritis and DAH. This case highlights the importance of considering SLE in the differential diagnosis of unexplained systemic symptoms and underscores the urgent need for medical intervention in DAH to substantially reduce mortality.

The Impact of Steroid Responder Status on Long-Term Outcomes in Critically Ill Patients With Acute Respiratory Distress Syndrome Receiving High-Dose Glucocorticoids.

Background and objective High-dose intravenous pulsed glucocorticosteroids (GCS) are not part of the standard treatment in acute respiratory distress syndrome (ARDS), and the evidence supporting their use is conflicting. In clinical practice, however, they are used in specialist settings when clinico-patho-radiological features suggest a potentially steroid-responsive pattern, or as a last resort in cases where patients are unable to be weaned off mechanical ventilation. This study aimed to investigate if an early objective response to high-dose GCS treatment in selected critically ill patients is predictive of survival in ARDS. Methods This study involved a case series of 63 patients treated at a tertiary specialist respiratory ICU between 2009 and 2017 who received high-dose GCS for ARDS following a multidisciplinary board agreement. Patients were stratified according to the change in their modified lung injury score (mLIS) between days 0 and 10 following GCS initiation. Changes in mLIS (range: 0-4) were grouped as follows - full responders: ≥2, partial responders: ≥1 and <2, and non-responders: <1. Mortality on discharge and at 6, 12, 18, and 24 months post-ICU discharge was assessed for each group. Data were analysed using logistic regression and a receiver operating curve (ROC) to determine a statistically significant association between the change in mLIS and survival. Results Of the 63 patients, there were seven full responders, 12 partial responders, and 44 non-responders to high-dose GCS. Overall mortality at ICU discharge and 6, 12, 18 and 24 months post-discharge was 29/63 (46.0%), 33/63 (52.4%), 34/63 (54.0%), 34/63 (54.0%), and 35/63 (55.6%) respectively. Mortality was significantly lower in the partial and full-response groups than in the non-response group at all time frames. Logistic regression showed a significant association between the change in mLIS and survival (p<0.001), and a ROC demonstrated that categorising the change in mLIS was a good predictive model for survival (c-statistic 0.86). Conclusions Measuring the change in mLIS by day 10 following high-dose GCS administration for ARDS may be clinically useful in prognosticating such patients. Further research using mLIS as a measure of response to GCS, and larger datasets to enable the evaluation of prognostic factors, may assist clinicians in predicting which patients with persistent ARDS are likely to respond to GCS therapy.

Managing Acute Intermediate Risk Pulmonary Thromboembolism in a Patient Who Developed Heparin-Induced Thrombocytopenia: Review of Current Guidelines and Literature.

Intermediate-risk pulmonary embolism describes hemodynamically stable patients with evidence of right ventricular strain, whereas high-risk pulmonary embolism comprises hemodynamic decompensation resulting in cardiogenic shock. The clinical manifestations of the two aforementioned conditions are challenging to treat in the setting of heparin-induced thrombocytopenia (HIT). Without immediate therapeutic anticoagulation, patients can subsequently deteriorate and require additional advanced therapies, with the end-goal of restoring pulmonary artery perfusion. We present the case of a male with bilateral intermediate-risk pulmonary emboli who developed type 2 HIT prompting different selection of appropriate management strategies.

A Case of Spontaneous Tumor Lysis After Pathologic Femur Fracture in Squamous Cell Lung Cancer.

Tumor lysis syndrome (TLS) occurs when large numbers of tumor cells lyse and release their contents, causing electrolyte derangements and renal injury. It is an uncommon complication of solid tumors and occurs most commonly after cytotoxic therapy rather than spontaneously. In this article, we describe a case of spontaneous TLS in a patient with squamous cell carcinoma of the lung. We also present a literature review of spontaneous TLS occurrence in solid tumors.

A Case Series of Spontaneous Pneumomediastinum With/Without Pneumothorax in COVID-19.

With the previous worldwide initial coronavirus disease 2019 (COVID-19) pandemic, a notable rise in spontaneous pneumomediastinum with/without pneumothorax (SPP) has been noted. Most cases were initially reported as complications secondary to barotrauma from mechanical ventilation (MV) with COVID-19. However, with the Delta strain, starting from December 2020, there have been multiple reports of SPP. The SPP is an uncommon complication outside use of assisted ventilation with either noninvasive positive pressure ventilation (NIPPV) or MV. COVID-19 has been linked to higher incidence of SPP without use of NIPPV or MV. We present a series of 5 cases with a polymerase chain reaction-confirmed COVID-19 diagnostic testing whose hospital course was complicated by SPP unrelated to the use of either NIPPV or MV.

Unexpected Barium Aspiration.

A barium esophagram is a diagnostic test used for the evaluation of dysphagia. However, this test has the potential risk for aspiration of the barium contrast. Barium aspiration typically localizes to the right lower lobe or left lingular lobe. We present a case of barium aspiration localized to the right middle lobe that persisted on chest X-ray. A 62-year-old male with a past medical history of hypertension, long-term back pain, gastritis, and anxiety presented with the complaints of hoarseness of voice, dysphagia, and weight loss for several months. During the esophagram, the patient aspirated the barium contrast. Chest X-ray confirmed the aspiration in the right middle lobe with a tree in bud appearance suggesting involvement of bronchioles. Three months later, a repeat chest X-ray revealed residual contrast. Pulmonary complications are directly related to the amount of aspirated barium and can include hypoxia, respiratory failure, secondary aspiration pneumonia, shock, and acute respiration distress syndrome. The prognosis of a barium aspiration is dependent on the amount of barium aspirated.

Achalasia and Cricopharyngeal Sphincter Dysfunction in a Patient With Myasthenia Gravis: A Case Report.

This case report describes an 82-year-old female patient with myasthenia gravis (MG) who presented with worsening dysphagia. The patient was found to have cricopharyngeal sphincter and esophageal achalasia, and a percutaneous endoscopic gastrostomy (PEG) tube was placed due to severe pharyngeal dysphagia and cricopharyngeal dysfunction. The patient had class IVb myasthenia gravis and was treated with intravenous immunoglobulin (IVIG), prednisone, and pyridostigmine. The report discusses the link between myasthenia gravis and dysphagia, which is seen in 20% of patients. The report also explores the relationship between myasthenia gravis and achalasia, which is a rare disorder characterized by the failure of relaxation of the sphincter muscles. While myasthenia gravis leads to muscle weakness and should not cause achalasia, there have been a few case reports describing a link between the two disorders. Cricopharyngeal dysfunction, which is a common disorder causing dysphagia in the elderly, was also noted in the patient. The report highlights that cricopharyngeal dysfunction may be primary or secondary, with the latter often being associated with inflammatory myopathies such as polymyositis or mixed connective tissue disorders. The patient did not have a workup for other autoimmune diseases that could have been the cause of achalasia.

Diffuse Alveolar Hemorrhage Synergistically Induced by Amiodarone and Rheumatoid Arthritis.

Diffuse alveolar hemorrhage (DAH) syndrome is characterized by bleeding into the alveolar spaces of the lungs and occurs when there is an injury to the alveolar microcirculation that leads to hemorrhage from the alveolar capillaries. We report a case of an 82-year-old woman who presented with acute respiratory distress. The patient had a history of rheumatoid arthritis (RA) and was on amiodarone for atrial fibrillation therapy. Initial diagnostic workup, including bronchoscopy and imaging studies, revealed diffuse opacities and the bronchoalveolar lavage fluid consistent with DAH. The patient required aggressive management with supportive care and corticosteroids. Laboratory work showed a synergistic effect between amiodarone and RA in inducing DAH. This makes the report unique as no reports in the literature described a synergic effect of amiodarone and RA in inducing DAH. The primary objective of this report is to guide physicians and remind them to keep DAH at the top of their differential diagnosis in the setting of an RA patient taking amiodarone.

Invasive Meningococcal Disease and COVID-19 Co-Infection: A Case Report.

This case report presents a 53-year-old male patient infected with COVID-19 who developed acute respiratory distress syndrome (ARDS) and septic shock due to meningococcemia, despite the absence of clinical signs of meningitis. This patient's condition was complicated by pneumonia in the setting of myocardial failure. In the curse of the disease, it is remarked that the importance of early recognition of sepsis symptoms is crucial in distinguishing patients with COVID-19 from those with other infections and preventing fatal outcomes. The case presented an excellent opportunity to review meningococcal disease's intrinsic and extrinsic risk factors. With the identified risk factors, we propose different measures to be considered to diminish and recognize this fatal disease early.

Shewanella putrefaciens: A Critically Emerging Pathogen of Ventilator-Associated Pneumonia.

Shewanella putrefaciens is a critically emerging cause of ventilator-associated pneumonia (VAP). S. putrefaciens ​​​​​is an oxidase-positive, nonfermenting, hydrogen-sulfide-producing, gram-negative bacillus. Worldwide, there have been six reported cases of ​​​​​​pneumonia and two reported cases of VAP, both caused by S. putrefaciens​​​​​. In this study, we discuss the case of a 59-year-old male who presented to the emergency department with altered mental status and acute respiratory distress. He was intubated for airway protection. Eight days following intubation, the patient developed symptoms consistent with VAP, and bronchoalveolar lavage (BAL) revealed S. putrefaciens​​​, an emerging nosocomial and opportunistic pathogen, as the causative agent. The patient was treated with cefepime with the resolution of symptoms.

Green Cytoplasmic Neutrophilic Inclusion Bodies in a Patient With Aspiration Pneumonia and Bowel Perforation.

Blue-green cytoplasmic neutrophilic inclusion bodies, previously described as "green crystals of death," are a rare but likely underreported finding in critically ill patients. This finding is associated with high mortality, ranging from 31% to 100% in published case studies. These inclusion bodies have been most strongly associated with acute liver injury and lactic acidosis, but they have also been reported in critically ill patients secondary to other etiologies. Here, we report a case of blue-green neutrophilic inclusion bodies in a patient with aspiration pneumonia and severe pneumoperitoneum secondary to bowel perforation. These blue-green neutrophilic inclusion bodies offer high prognostic value for physicians, and their presence should be considered a "critical result," indicating the severity of the patient's illness.

Unusual Presentation of Multiple Lung Nodules in a Patient With Supraglottic Squamous Cancer: A Rare Infectious Cause Revealed.

Pulmonary nodules are commonly encountered in medical practice, necessitating thorough evaluation due to their diverse etiologies. Identifying the underlying cause is of utmost importance, particularly in patients with a history of extrapulmonary cancer, to differentiate between metastasis and other etiologies. We present a rare case of a 24-year-old male with supraglottic squamous cancer who developed multiple pulmonary nodules, which surprisingly were caused by a rare infectious agent. The patient presented with bilateral infiltrates on imaging, raising strong suspicion of metastatic disease from primary cancer. However, bronchoscopy and biopsy revealed no malignancy but confirmed the presence of Corynebacterium amycolatum, leading to a change in the treatment approach from palliative to curative. This case highlights the importance of considering other etiologies, especially infections, in patients with cancer and pulmonary nodules. Accurate diagnosis is crucial to guide appropriate management decisions and optimize patient outcomes.

Point-of-Care Ultrasound Unveils Life-Threatening Conditions: A Case Series Highlighting Its Vital Diagnostic Role.

Point-of-care ultrasound (POCUS) has emerged as a powerful diagnostic tool in healthcare, offering rapid and cost-effective evaluation of cardiovascular and respiratory conditions. This case series highlights the vital role of POCUS in diagnosing life-threatening conditions and emphasizes the need for adequate training in its use. The first case describes a patient with chest pain, where POCUS revealed findings suggestive of thoracic aortic dissection, leading to timely transfer and surgical repair. The second case involves a patient with altered mental status and hypoxia, where POCUS identified a right atrial thrombus leading to thrombectomy. The discussion explores the expanding applications of POCUS in various medical specialties, including critical care and trauma, and its potential to improve patient outcomes. While POCUS has shown great promise, it remains a user-dependent technology, necessitating comprehensive training and collaboration among healthcare professionals to ensure its effective and safe use.

The Forgotten Complication of Nasogastric Tube Insertion: Esophageal Perforation and Associated Hydropneumothorax and Hydropneumoperitoneum.

Nutritional support is essential for critically ill patients to reduce mortality and length of stay. Frequently nasogastric (NG) tubes are used to provide enteral nutrition. A very rare risk of NG tube placement is esophageal perforation, most commonly in the thoracic portion of the esophagus. Here we describe a case of a 41-year-old male with multiple risk factors for esophageal integrity disruption who initially presented for diabetic ketoacidosis (DKA) requiring intubation. Following intubation, an NG tube was placed for nutritional support. The following day the patient developed hydropneumothorax and hydropneumoperitoneum. He was taken emergently for surgical correction of suspected perforation. It was found that the patient had esophageal perforation from the distal esophagus to the proximal portion of the lesser curvature of the stomach. The NG tube transversed the proximal portion of the tear and re-entered at a distal site. The distal portions of the esophagus showed necrotic superficial layers with viable muscularis layers. The patient gradually improved after surgical intervention and was discharged to a long-term acute care facility. It is essential as medical providers to be familiar with complications of NG tube placement and risk factors that could increase the risk of esophageal perforation.
