Tuberculosis, being an airborne disease with a broad spectrum of symptoms and signs, is a rare cause of chylothorax. Mortality due to tuberculous chylothorax is 6%, and bilateral chylothorax has a higher mortality with a poor prognosis. A previously well 28-year-old male with a household contact history of tuberculosis exposure presented with a 1-month history of shortness of breath, fever, pleuritic chest pain, and constitutional symptoms. He was found to have bilateral chylothorax, generalized lymphadenopathy, hepatosplenomegaly, and miliary nodules in chest x-ray. Sputum acid-fast bacilli, pleural fluid TB PCR (Tuberculosis polymerase chain reaction) and culture became negative. Sputum culture became positive for at 6 weeks. He had marked clinical and radiological improvement within 2 months of starting anti-tuberculosis treatment. Diagnosis of pleural tuberculosis is difficult as pleural fluid acid-fast bacilli detection has poor sensitivity. It is important to consider tuberculosis in patients with chylothorax and initiate prompt treatment.

Daptomycin is an antibiotic used for resistant Gram-positive organisms and has the rare side effect of inducing acute eosinophilic pneumonia (AEP). This condition can be fatal due to respiratory failure if not treated, as eosinophils migrate to the lungs and inflammatory cascades cause epithelial injury. Daptomycin-induced AEP can be misdiagnosed as bacterial pneumonia or malignancy, which may lead to unnecessary testing or treatments. Diagnostic criteria include dyspnea, fever, recent daptomycin exposure, infiltrates on imaging, eosinophils on bronchoalveolar lavage or peripheral eosinophilia, and clinical improvement with medication discontinuation. We present a unique case of daptomycin-induced eosinophilic pneumonia in a 72-year-old male with the chief complaint of dyspnea and initial concerns for lung cancer after a spiculated nodule was seen on imaging. Prior to undergoing a lung biopsy, repeat imaging showed a decrease in the suspicious nodule, reducing the likelihood of malignancy and prompting a re-evaluation of the history of the present illness and medication list. Daptomycin was stopped, and the patient's symptoms and imaging improved. This case illustrates the importance of early recognition and appropriate treatment of AEP, which allows for complete clinical recovery.

Acute post-streptococcal glomerulonephritis (APSGN) is the most common glomerulonephritis of childhood, and clinical presentation can vary widely. This case report presents an atypical manifestation of APSGN in an 8-year-old female patient with pleuritic chest pain and elevated troponin-I, despite lacking classical kidney symptoms. Imaging studies showed cardiomegaly and interstitial lung opacities. Further investigations revealed hematuria and proteinuria, and the diagnosis was confirmed through elevated antistreptolysin-O (ASO) titers and low complement 3 (C3) levels. The patient was successfully managed with fluid restriction, diuretics, and antihypertensives, resulting in the resolution of symptoms and normalization of laboratory values. This case highlights the significance of recognizing atypical manifestations of APSGN for ensuring prompt diagnosis and proper management in the pediatric population.

We present the case of a 64-year-old female with a past medical history significant for unclassified interstitial lung disease (ILD) from suspected hypersensitivity pneumonitis secondary to chronic mold exposure with steroid responsiveness and prior pneumothorax. The patient developed shortness of breath and pleuritic chest pain after undergoing routine outpatient pulmonary function tests (PFTs). She was immediately transferred to the emergency department and found to have a moderate left basilar pneumothorax. She underwent emergent surgical chest tube placement followed by doxycycline pleurodesis. Repeat chest imaging showed inadvertent retraction of the chest tube and extensive subcutaneous emphysema. The surgical chest tube was replaced by a pigtail catheter with an improvement of subcutaneous emphysema. This case demonstrates the development of a rare but serious complication of pneumothorax that could occur in patients who have ILD undergoing routine PFTs. Clinicians should be aware of this risk when patients who have ILD present for PFTs and counsel them to seek immediate medical attention if they develop signs of acute onset dyspnea after performing PFTs.

Behcet's disease (BD) is a chronic and inflammatory vasculitis characterized by recurrent oral and genital aphthous ulcers, uveitis, and skin lesions. Although there is a high rate of deep vein thrombosis in BD, pulmonary arterial thromboembolism (PTE) is a rare complication. We present a 30-year-old patient who was admitted with pleuritic chest pain, non-massive hemoptysis since 4 days ago and medical history of intermittent genial aphthous lesions, and skin lesions. During our evaluation, he had an S1Q3T3 pattern in the electrocardiogram, a high level of D-dimer, a low level of FDP and fibrinogen along with pulmonary emboli in lobar and segmental branches of the right pulmonary artery and segmental branches of left lower lobe pulmonary artery were detected in his pulmonary CT Angiography. Then, he was positive for HLA-B51. Based on his clinical condition and history of recurrent genital and skin lesions, a positive pathergy test. Therefore, the diagnosis of BD was confirmed for him. Diagnosis of PTE can be difficult due to the rarity of PTE in BD and nonspecific clinical symptoms; therefore, a high degree of suspicion and appropriate radiographic imaging is essential for the diagnosis.

BACKGROUND
Coronary artery fistulae are rare cardiovascular anomalies that can present with atypical symptomatology and therefore pose diagnostic challenges, especially in young patients.
CASE SUMMARY
A 34-year-old woman presented with left-sided pleuritic chest pain, haemoptysis, and flu-like symptoms. Initial evaluation revealed multiple left-sided pulmonary emboli, and her transthoracic echocardiography showed turbulent flow in a dilated coronary sinus. A right coronary artery (RCA) to coronary sinus fistula was confirmed by computed tomography coronary angiogram. The patient was treated with lifelong anticoagulation, and a subsequent stress cardiac magnetic resonance imaging did not show inducible myocardial ischaemia. As such, the patient was managed conservatively.
DISCUSSION
Utilization of multi-modality imaging is of utmost importance for diagnostic and therapeutic purposes in coronary artery fistulae. In this case report, our patient presented with unprovoked pulmonary emboli, which could be caused by the turbulent flow and stasis, due to the RCA-to-coronary sinus fistula.

BACKGROUND
Sodium azide exposures are rare but can be lethal as the substance inhibits complex IV in the electron transport chain, blocking adenosine-triphosphate (ATP) synthesis. Sodium azide is mostly used as a propellant in vehicular airbags but is also used in laboratory, pharmacy, and industrial settings. No known antidote exists and its cardiotoxic effects are poorly described in the literature.
CASE SUMMARY
We describe the case of a 31-year-old patient with major depressive disorder presenting with altered mental status after ingestion of an unknown amount of sodium azide. Although initially chest pain free, she developed pleuritic chest pain 48 h after ingestion. This was accompanied by new diffuse ST elevations on the electrocardiogram and serum troponin elevations concerning for myopericarditis. Treatment was pursued with a 14-day course of colchicine resulting in complete symptom resolution within 4 days of treatment initiation. The patient's transthoracic echocardiogram was only notable for a preserved left ventricular ejection fraction (LVEF).
DISCUSSION
Cardiac toxicity after sodium azide ingestion usually occurs days after ingestion and has been previously described in the forms of heart failure with reduced ejection fraction complicated by cardiogenic shock. We describe the first case of sodium azide-induced myopericarditis with a preserved LVEF treated with colchicine. Colchicine is an established treatment for pericarditis, but its inhibition of endocytosis, an ATP-dependent cellular function, could be mechanistically relevant to this case.

Review
BACKGROUND
Undifferentiated autoinflammatory diseases are characterized by recurrent or persistent fever, usually combined with other inflammatory manifestations, and negative or inconclusive genetic studies for monogenic autoinflammatory disorders.
AIMS
To define and characterize disease phenotypes in adult patients diagnosed in an adult reference center with undifferentiated autoinflammatory diseases, and to analyze the efficacy of the drugs used in order to provide practical diagnostic and therapeutic recommendations.
METHODS
Retrospective study (2015-2022) of patients with undifferentiated autoinflammatory diseases among all patients visited in our reference center. Demographic, clinical, laboratory features and detailed therapeutic information was collected.
RESULTS
Of the 334 patients with a suspected autoinflammatory disease, 134 (40%) patients (61% women) were initially diagnosed with undifferentiated autoinflammatory diseases. Mean age at disease onset and at diagnosis was 28.7 and 37.7 years, respectively. In 90 (67.2%) patients, symptoms started during adulthood. Forty-four (32.8%) patients met diagnostic/classification criteria for adult PFAPA syndrome. In the remaining patients, four additional phenotypes were differentiated according to the predominant manifestations: a) Predominantly fever phenotype (n = 18; 13.4%); b) Predominantly abdominal/pleuritic pain phenotype (n = 9; 6.7%); c) Predominantly pericarditis phenotype (n = 18; 13.4%), and d) Complex syndrome phenotype (n = 45; 33.6%). Prednisone (mainly on demand), colchicine and anakinra were the drugs commonly used. Overall, complete responses were achieved with prednisone in 41.3%, colchicine in 40.2%, and anakinra in 58.3% of patients in whom they were used. By phenotypes, prednisone on demand was more effective in adult PFAPA syndrome and colchicine in patients with the abdominal/pleuritic pain pattern and PFAPA syndrome. Patients with complex syndrome achieved complete responses with prednisone (21.9%), colchicine (25.7%) and anakinra (44.4%), and were the group more often requiring additional immunosuppressive drugs.
CONCLUSIONS
The analysis of the largest single-center series of adult patients with undifferentiated autoinflammatory diseases identified and characterized different disease phenotypes and their therapeutic approaches. This study is expected to contribute to increase the awareness of physicians for an early identification of these conditions, and to provide the best known therapeutic options.

Epithelioid hemangioendothelioma (EHE) is a rare vascular neoplasm with a clinical behaviour that falls between a benign hemangioma and a high-grade angiosarcoma. Pleural EHE is exceptionally rare, and its prognosis is grim, with most patients experiencing survival of less than 1 year. Here, we present a case of pleural EHE in a 45-year-old woman with a month-long history of right-sided pleuritic chest pain. Chest computed tomography revealed consolidation, atelectasis of the right lung, right pleural thickening, and pleural effusion. She underwent video-assisted thoracoscopic surgery for decortication and was diagnosed with conclusively pleural EHE, showing a CAMTA1 rearrangement. Paclitaxel treatment, administered once weekly on days 1, 8 and 15 of a 28-day cycle, resulted in a stable disease after 12 cycles. Managing patients with pleural EHE is challenging because there are still no established standard treatments. Our case achieved 11-month progression-free survival following paclitaxel treatment.

Myelotoxicity and kidney dysfunction related to the use of trimethoprim-sulfamethoxazole for the treatment of Pneumocystis jirovecii pneumonia: a case report of severe adverse events with a common drug.
Trimethoprim-sulfamethoxazole (TMP-SMX) is the primary therapeutic option for Pneumocystis jirovecii pneumonia (PCP). Gastrointestinal symptoms and cutaneous rash are common side effects, with hyperkalemia being uncommon in patients without kidney dysfunction, and myelotoxicity being even rarer. We present the case of a male patient with hypertension and a recent diagnosis of non-Hodgkin lymphoma, undergoing rituximab treatment for two months. He was admitted to the intensive care unit due to dyspnea, tachypnea, and pleuritic pain, requiring mechanical ventilation. Chest computed tomography showed bilateral and multilobed ground-glass opacities, compromising more than 80% of the lung parenchyma. Pulmonary tuberculosis and COVID-19 were ruled out. An angiotomography and Doppler ultrasound revealed an extensive pulmonary thrombus and deep venous thrombosis. Empiric treatment with TMP-SMX for PCP was initiated, but within four days, the patient experienced metabolic acidosis and severe hyperkalemia, necessitating hemodialysis. He also presented with progressive pancytopenia and critical levels of leukopenia and thrombocytopenia. The hypothesis of TMP-SMX-induced myelotoxicity was suspected. Considering the unavailability of an alternative treatment, it was opted to continue TMP-SMX and initiate a granulocyte-colony-stimulating factor. However, the patient maintained medullary deterioration, becoming refractory to the transfusion of blood derivates. On the 17th day of treatment, a clinical decision was made to suspend TMP-SMX, leading to improvements within 48 hours in marrow and kidney functions, metabolic acidosis, and hyperkalemia. Despite all efforts, the patient died after 35 days of hospitalization due to hospital-acquired infections. This case highlights the importance of clinicians recognizing potential myelotoxicity with TMP-SMX and promptly discontinuing the drug if necessary.
