Pulmonary edema is a rare mechanism of death that develops after partial hanging, a potential complication that physicians should consider early in the management of these patients. This case series discusses the presentation, evaluation, and treatment course of three patients who had attempted suicide by hanging and were admitted to the hospital. These patients were admitted to the intensive care unit after being stabilized and supportive treatment was provided. In all the cases, a radiological scan of the chest revealed diffuse infiltrates consistent with pulmonary edema on both sides, features of which were also noted during a diagnostic bronchoscopy. After providing the best intensive care in the hospital, two patients clinically improved, and one patient succumbed to cardiac arrest. As most patients will be brought dead to the hospital following hanging, negative pressure pulmonary edema remains underdiagnosed. Thus, this case series enumerates the possible etiologies of negative pressure pulmonary edema and its contribution to death following suicidal hanging.

This article presents the case of a 57-year-old woman with a history of rheumatoid arthritis who developed severe coronavirus disease 2019 (COVID-19) pneumonia that progressed to acute respiratory distress syndrome (ARDS) and multi-system organ failure. Despite initial slow progression and multiple hospital readmissions, her condition rapidly deteriorated, leading to full respiratory failure requiring intubation and ventilation. She was transferred to a specialized center where she underwent extracorporeal membrane oxygenation (ECMO) and hemodialysis for acute renal failure. Unfortunately, she remained dependent on ECMO for an extended period of six months. Although she made a gradual recovery, the prolonged critical care treatment resulted in critical ischemia of multiple extremities, necessitating a below-knee amputation (BKA) of her left lower extremity and transmetatarsal amputations of her right hand. This case reports one of the longest ECMO treatments for COVID-19 and associated comorbidities in the literature. Clinicians could include a longer duration of treatment and potential associated disabilities in the informed consent.

Coccidioidomycosis is a fungal infection prevalent in the Southwestern United States and Northern Mexico. Given its rarity and often asymptomatic nature, disseminated coccidioidomycosis frequently omitted in preliminary differential diagnoses. Our case study presents the postmortem results of an individual who had a reactivated coccidioidomycosis, causing diffuse alveolar damage and resulting in his death. This case study underscores the importance of considering coccidioidomycosis in initial differential diagnoses, particularly in patients with prior exposure to the infection and associated risk factors.

BACKGROUND: Hematopoietic stem cell transplantation (HSCT) was associated with potentially life-threatening complications. Among patients supported by extracorporeal membrane oxygenation (ECMO), those who underwent HSCT had a worse prognosis than those who did not. Advances in HSCT and critical care management have improved the prognosis of ECMO-supported HSCT patients.
METHODS: The patient in the remission stage of lymphoma after 22 months of allogeneic hematopoietic stem cell transplantation, suffered from ARDS, severe neutropenia, thrombocytopenia, and long-term COVID-19. We evaluated the benefits and risks of ECMO for the patient, including the possibility of being free from ECMO, the status of malignancy, the interval from HSCT to ARDS, the function of the graft, the amount of organ failure, and the comorbidities. ECMO was ultimately used to save his life.
CONCLUSIONS: We did not advocate for the general use of ECMO in HSCT patients and we believed that highly selected patients, with well-controlled tumors, few comorbidities, and fewer risk factors for death, tended to benefit from ECMO with well ICU management.

We present a case of reverse McConnell\'s sign, a rare echocardiographic finding of right ventricular apical hypokinesis and basal hyperkinesis, in a patient with acute respiratory distress syndrome and septic shock. Although multiple etiologies were hypothesized, providers attributed this cardiomyopathy to increased right heart afterload from hypoxic pulmonary vasoconstriction. Cardiac function normalized as the patient\'s respiratory failure and sepsis resolved. This study highlights the value of early echocardiography to help guide management in critical illness. In our case, this finding helped initiate diuresis and establish a baseline for monitoring cardiac function as this patient\'s critical illness resolved. Literature has most commonly associated reverse McConnell\'s sign with massive pulmonary embolism and, more rarely, takotsubo cardiomyopathy. Given the absence of PE, takotsubo, or other identifiable cause, this case suggests that reverse McConnell\'s sign may more generally indicate acutely increased right ventricular afterload rather than a specific diagnosis. When reverse McConnell\'s sign is detected, treatment should focus on reversible causes of elevated right heart pressure (e.g., volume overload, PE) and increased pulmonary resistance.

Illicit drug usage (IDU) is a big challenge in clinical practice, with increasing incidence in the last decades. Daily, clinicians encounter a wide variety of complications related to IDU. Common infections related to illicit drugs are infective endocarditis, abscesses, osteomyelitis, pneumonia, HIV, hepatitis C, and B. Other rare complications could happen like leukoencephalopathy, IDU-related lung injury, and acute respiratory distress syndrome (ARDS) which is a severe and potentially life-threatening condition characterized by the sudden onset of respiratory failure, often necessitating mechanical ventilation. While the most common etiologies of ARDS are related to infections and sepsis, there is emerging evidence that substance abuse can also be associated with the development of ARDS with unclear mechanisms. IDU-related lung injury is a rare entity with few cases reported in the literature. Its management usually involves supportive care, including mechanical ventilation, oxygen therapy, and close monitoring of fluid balance. We present a case of a 25-year-old male presented with ARDS and multiorgan failure related to methamphetamine and cannabis abuse.

UNASSIGNED: Patients suffering from severe acute respiratory distress syndrome (ARDS) are usually treated with mechanical ventilation. Extracorporeal membrane oxygenation (ECMO) has traditionally been considered a life-saving therapy and was reserved as a last resort when other treatment options were exhausted. However, this report outlines our successful initial experience with early implementation of awake venovenous extracorporeal membrane oxygenation (VV-ECMO) in a case of pneumocystis jirovecii pneumonia complicated by severe acute respiratory distress syndrome (ARDS), offering a promising new approach for recovery.
UNASSIGNED: We present a case report of the effective application of awake VV-ECMO in a 29 years-old man with severe ARDS caused by pneumocystis jirovecii pneumonia. The patient initially received antibiotic treatment and non-invasive ventilation (NIV) for respiratory distress, but these interventions failed to improve the worsening dyspnea that occurred in the patient. Following the combined antifungal therapy, high-flow nasal cannula (HFNC) oxygen therapy, and VV-ECMO for a duration of 7 days, the patient\'s symptoms improved, showing relief.
UNASSIGNED: Awake VV-ECMO proved to be an effective treatment for critically ill patients with ARDS, avoiding the need for invasive mechanical ventilation. However, increased clinical evidence is needed to verify whether awake ECMO could be widely used in severe ARDS caused by other diseases or conditions.

Most influenza B infections are self-limited, but in some instances, they can cause substantial morbidity and mortality due to complications. Acute fulminant cerebral edema (AFCE) is one of the rare complications. AFCE, a consequence of acute encephalitis, presents as acute onset of alteration in mental status, seizure, and/or headache followed by rapidly progressive encephalopathy, often leading to death. The exact pathophysiology of AFCE is unknown, but many pathomechanisms have been proposed. We present a case of an 18-year-old female in excellent physical condition who presented with respiratory insufficiency after being recently diagnosed with influenza B infection. Three days later, she developed acute encephalopathy, leading to brain death. To our knowledge, this rare case of AFCE developing following influenza B infection is the first reported case outside the pediatric population.

Cryptogenic organizing pneumonia (COP) and idiopathic eosinophilic pneumonia (IEP) are two forms of diffuse interstitial lung diseases (ILD) that lead to a rapid respiratory decline in young patients. Both conditions presented with similar clinical and radiological findings, making a clinical diagnosis challenging. They are both considered diagnoses of exclusion, and the treatment for both conditions is high-dose corticosteroids, leading to a quick recovery. Pathological specimens are often required prior to initiating appropriate treatment, leading to significant delays in appropriate therapy and a poorer prognosis. In this case report, we suggest that clinical pearls can be used to establish either diagnosis earlier, which leads to earlier treatment and better outcomes. Our patient presented with an acute respiratory distress syndrome (ARDS) picture, bilateral interstitial infiltrates with peripheral predominance, eosinophilia, and a negative initial infectious and cardiac workup. Based on these findings, we had a high initial suspicion that either COP or IEP was present. Our patient had a bronchoscopy done and was promptly started on steroid therapy soon after, which led to rapid clinical improvement. Pathological specimens were inconclusive, but the patient continued to improve, thereby confirming the presence of either form of ILD. The patient was subsequently discharged home with oxygen and recommended to follow up with a pulmonologist for further outpatient testing and management.

Thoracic surgeries involving resection of lung tissue pose a risk of severe postoperative pulmonary complications, including acute respiratory distress syndrome (ARDS) and respiratory failure. Lung resections require one-lung ventilation (OLV) and, thus, are at higher risk of ventilator-induced lung injury (VILI) attributable to barotrauma and volutrauma in the one ventilated lung, as well as hypoxemia and reperfusion injury on the operated lung. Further, we also aimed to assess the differences in localized and systemic markers of tissue injury/inflammation in those who developed respiratory failure after lung surgery versus matched controls who did not develop respiratory failure. We aimed to assess the different inflammatory/injury marker patterns induced in the operated and ventilated lung and how this compared to the systemic circulating inflammatory/injury marker pattern. A case-control study nested within a prospective cohort study was performed. Patients with postoperative respiratory failure after lung surgery (n = 5) were matched with control patients (n = 6) who did not develop postoperative respiratory failure. Biospecimens (arterial plasma, bronchoalveolar lavage separately from ventilated and operated lungs) were obtained from patients undergoing lung surgery at two timepoints: (1) just prior to initiation of OLV and (2) after lung resection was completed and OLV stopped. Multiplex electrochemiluminescent immunoassays were performed for these biospecimen. We quantified 50 protein biomarkers of inflammation and tissue injury and identified significant differences between those who did and did not develop postoperative respiratory failure. The three biospecimen types also display unique biomarker patterns.
