BACKGROUND Tension pneumothorax (TP) is a medical emergency resulting in air accumulation in the pleural cavity of the affected side. Later, this air applies pressure on the mediastinal structures, leading to a shift of these structures toward the contralateral side. This shift results in a picture of obstructive shock with a possibly fatal consequence if not detected and treated early. Treatment should not await radiological confirmation, and the red flags in the history and physical examination are enough to proceed with decompressing the affected hemithorax with a large-bore needle. Usually, patients with TP present to the Emergency Department with pleuritic chest pain and shortness of breath, but rare presentations are still possible. CASE REPORT We report a case of a 24-year-old male patient with TP who presented to the Emergency Department with severe epigastric abdominal pain with a clinical picture of acute pancreatitis. X-ray showed a right-sided TP. Immediately, we performed a needle decompression followed by chest tube insertion. Four days later, the patient was discharged home uneventfully. CONCLUSIONS In this case report, we aim to draw the attention of physicians in the Emergency Department to the need to consider the possibility of upper abdominal pain elicited by chest pathologies. Furthermore, we need to investigate the effect of TP on coronary perfusion.

BACKGROUND
Eosinophilic myocarditis (EM) secondary to eosinophilic granulomatosis with polyangiitis (EGPA) is a rare disease, for which cardiac magnetic resonance imaging (CMRI) is a useful non-invasive modality for diagnosis. We present a case of EM in a patient who recently recovered from COVID-19 and discuss the role of CMRI and endomyocardial biopsy (EMB) to differentiate between COVID-19-associated myocarditis and EM.
CASE SUMMARY
A 20-year-old Hispanic male with a history of sinusitis and asthma, and who recently recovered from COVID-19, presented to the emergency room with pleuritic chest pain, dyspnoea on exertion, and cough. His presentation labs were pertinent for leucocytosis, eosinophilia, elevated troponin, and elevated erythrocyte sedimentation rate and C-reactive protein. The electrocardiogram showed sinus tachycardia. Echocardiogram showed an ejection fraction of 40%. The patient was admitted, and on day 2 of admission, he underwent CMRI which showed findings of EM and mural thrombi. On hospital day 3, the patient underwent right heart catheterization and EMB which confirmed EM. The patient was treated with steroids and mepolizumab. He was discharged on hospital day 7 and continued outpatient heart failure treatment.
DISCUSSION
This is a unique case of EM and heart failure with reduced ejection fraction as a presentation of EGPA, in a patient who recently recovered from COVID-19. In this case, CMRI and EMB were critical to identify the cause of myocarditis and helped in the optimal management of this patient.

Tuberculosis (TB) is a chronic infectious disease with high mortality caused by the Mycobacterium tuberculosis complex (MTC). Its clinical symptoms include a prolonged cough with mucus, pleuritic chest pain, hemoptysis, etc., and predominant complications such as tuberculous meningitis and pleural effusion. Thus, developing rapid, ultrasensitive, and highly specific detection techniques plays an important role in controlling TB. Here, we devised CRISPR/CRISPR-associated 12b nuclease (CRISPR/Cas12b)-based multiple cross displacement amplification technique (CRISPR-MCDA) targeting the sequence and used it to detect MTC pathogens. A newly engineered protospacer adjacent motif (PAM) site (TTTC) was modified in the linker region of the CP1 primer. In the CRISPR-MCDA system, the exponentially amplified MCDA amplicons with the PAM sites can guide the Cas12b/gRNA complex to quickly and accurately recognize its target regions, which successfully activates the CRISPR/Cas12b effector and enables ultrafast -cleavage of single-stranded DNA reporter molecules. The limit of detection of the CRISPR-MCDA assay was 5 fg/μL of genomic DNA extracted from the MTB reference strain H37Rv. The CRISPR-MCDA assay successfully detected all examined MTC strains and there was no cross-reaction with non-MTC pathogens, confirming that its specificity is 100%. The entire detection process can be completed within 70 min using real-time fluorescence analysis. Moreover, visualization detection (under UV light) was also designed to verify the results, eliminating the use of specialized instruments. In conclusion, the CRISPR-MCDA assay established in this report can be used as a valuable detection technique for MTC infection. The Mycobacterium tuberculosis complex pathogen is a crucial infectious agent of tuberculosis. Hence, improving the capability of MTC detection is one of the most urgently required strategies for preventing and controlling TB. In this report, we successfully developed and implemented CRISPR/Cas12b-based multiple cross displacement amplification targeting the sequence to detect MTC pathogens. These results demonstrated that the CRISPR-MCDA assay developed in this study was a rapid, ultrasensitive, highly specific, and readily available method which can be used as a valuable diagnostic tool for MTC infection in clinical settings.

Case report: a breathtaking complication after ablation-using multi-modal imaging for timely diagnosis of acquired pulmonary vein stenosis and its implication for effective management.
BACKGROUND
Acquired pulmonary vein stenosis (PVS) is a rare, but serious, complication that can develop after treatment with ablations for atrial fibrillation. Prompt diagnosis is difficult because it can often present similarly to other pulmonary disease processes.
CASE SUMMARY
We describe a 62-year-old female with history of persistent symptomatic atrial fibrillation that resolved status post two radio-frequency ablations who presents with ongoing dyspnoea, productive cough, pleuritic chest pain, and haemoptysis over multiple admissions. She was misdiagnosed with recurrent pneumonias and pulmonary embolism that failed to improve her symptoms. She was referred to our centre for further evaluation finding severe stenosis in the left superior pulmonary vein with complete obliteration of the left inferior pulmonary vein on computed tomography scan. Multi-modal imaging including an echocardiogram and pulmonary angiogram was used to confirm the diagnosis. Percutaneous intervention with transvenous pulmonary vein venoplasty with pulmonary vein stenting of the left upper pulmonary vein was offered which resolved the patient's aforementioned symptoms.
CONCLUSION
Prompt diagnosis of acquired pulmonary vein stenosis is critical to plan for effective management. Our case highlights the need to consider PVS with a high index of clinical suspicion when a patient's medical history is significant for a prior history of ablation. We also review the use of multi-modal imaging to diagnose and plan for effective management with percutaneous intervention.

Lung cancer is the third most common cancer in the United States. Lung adenocarcinoma is a subtype of non-small cell lung cancer. On computed tomography (CT) it can appear as ground glass nodules, consolidative opacity, or solid mass lesions located in the periphery. Because it can appear as a consolidation, it can sometimes be confused with an infectious process such as pneumonia. We present a case of a 27-year-old male initially diagnosed with pneumonia; however, three months later, when he presented to the hospital with worsening pleuritic chest pain, fever, and dyspnea after a bronchoscopy a week before admission, pathology was positive for adenocarcinoma.

INTRODUCTION AND IMPORTANCE
NUT (nuclear protein in testis) carcinoma of the lung is an aggressive, poorly differentiated squamous cell carcinoma that has a poor prognosis. Currently, there are no recommended guidelines with limited literature regarding the management of primary NUT carcinoma of the lung.
CASE PRESENTATION
A 28-year-old male presented with 2 weeks of intractable chest pain and shortness of breath and was found to have Stage IV pleural NUT carcinoma. After 2 cycles of chemoimmunotherapy, the patient's symptoms persisted with worsening functional status. Palliative surgery was performed via an extrapleural pneumonectomy with significant improvement in symptoms and activities of daily living.
CLINICAL DISCUSSION
With no current treatment guidelines, we demonstrate the benefit of surgical resection of advanced pleural NUT carcinoma to improve quality of life. Prognosis is poor with a median survival around 7 months and 3 months with an associated mass. The patient presented pre-operatively with intractable pleuritic chest pain and shortness of breath, limiting activities of daily living that persisted despite chemoimmunotherapy. Our surgical goal was to improve the patient's respiratory status and mitigate pain symptoms via extensive surgical debulking. The patient was able to achieve a higher quality of life and survived longer than the median average, passing away 1 year after diagnosis.
CONCLUSION
The management of NUT carcinoma of the lung remains challenging. The role of surgical resection for palliation in advanced tumors has not been previously described and may provide improved quality of life in carefully selected patients.

Signet-ring cell carcinomas are an aggressive, poorly differentiated, and highly invasive adenocarcinoma carrying a poor prognosis. Most of these tumors originate in gastrointestinal organs; however, primary lung signet-ring cell adenocarcinomas can rarely occur. Tumoral lymphatic infiltration is a complication of these tumors and can cause phenomena such as lymphangitic carcinomatosis, characterized by a nodular thickening of the pleura, pleural effusions, and mediastinal lymphadenopathies. We report a case of a 63-year-old ex-smoker with a 2-week clinical course of dyspnea and pleuritic chest pain in which a nodular thickening of the pleura and pleural effusion were documented and led to the diagnosis of a primary signet-ring cell adenocarcinoma of the lung with lymphangitic carcinomatosis. This complication has never been described in the context of a primary lung tumor of this subtype. Both entities carry a high mortality and have no therapeutical options. This report adds to the information available about them.

Tuberculosis is a primary lung disease that can spread to the lymph nodes, vertebrae, and gastrointestinal tract. The esophagus can be affected by mediastinal lymphadenitis, mostly in immunocompromised patients, leading to the formation of esophagomediastinal fistulas. They can cause dysphagia, pleuritic chest pain, and choking coughs from recurrent aspiration. The treatment is surgery but endoscopic interventions using over-the-scope endoclips, stents, medical adhesives, and sutures are successful alternatives. We present a case of an esophagomediastinal fistula in a patient with tuberculosis and human immunodeficiency virus that was successfully treated with through-the-scope endoclips.

Tumor lysis syndrome (TLS) is an oncological emergency characterized by the massive destruction of malignant cells and the release of their contents into the extracellular space, which might occur spontaneously or post-chemotherapy. According to the , it can be defined by both laboratory criteria: hyperuricemia, hyperkalemia, hyperphosphatemia, hypocalcemia (two or more); and clinical criteria: acute kidney injury (AKI), convulsions, arrhythmias, or death. We report the case of a 63-year-old man with a previous medical history of colorectal carcinoma and associated multiorgan metastasis. The patient was initially admitted to the Coronary Intensive Care Unit, five days after the chemotherapy session, on suspicion of Acute Myocardial Infarction. Upon admission, he presented without significant elevation of myocardial injury markers, but with laboratory abnormalities (hyperkalemia, hyperphosphatemia, hyperuricemia, and hypocalcemia) and clinical symptoms (sudden sharp chest pain with pleuritic characteristics and electrocardiographic anomalies suggesting uremic pericarditis, and acute kidney injury), all consistent with TLS. The best approach to established TLS is aggressive fluid therapy and a decrease in uric acid levels. Rasburicase proved to be notoriously more effective, both in terms of prevention and treatment of established TLS, thus consisting of the first-line drug. However, in the present case, rasburicase was not available at the hospital level, so a decision was made to initiate treatment with allopurinol. The case evolved with slow but good clinical evolution. Its uniqueness resides in its initial presentation as uremic pericarditis, scarcely described in the literature. The constellation of metabolic alterations from this syndrome translates into a spectrum of clinical manifestations that can go unnoticed and ultimately may prove to be fatal. Its recognition and prevention are crucial for improving patient outcomes.
