Rapidly-Developing Pleural Effusion: Explosive Pleuritis Caused by Group A Streptococcal Infection.

Community-acquired pneumonia is a leading cause of death from infectious diseases globally. Parapneumonic effusion is one of the most common complications of community-acquired pneumonia. As the infection progresses within the pleural space, loculation and empyema may develop. In rare cases, the parapneumonic effusions can progress significantly within 24 hours, which has been described as explosive pleuritis and may confer additional morbidity. Group A Streptococcus is the leading causative microorganism, which in itself has higher rates of parapneumonic effusions. We describe the case of a 30-year-old-female with a past medical history of asthma who presented to the emergency department with a sore throat, cough, and runny nose and was discharged on the same day after treatment of asthma exacerbation with upper respiratory tract infection. She re-presented within 24 hours with shortness of breath and right-sided pleuritic chest pain. Chest x-ray showed a new, large right-sided pleural effusion for which pleural fluid culture grew group A Streptococcus. She ultimately had prolonged hospitalization, requiring chest tube placement, and video-assisted thoracoscopic surgery (VATS). VATS was unsuccessful and she was treated with long-term antibiotics. This case demonstrates the dramatic evolution of explosive pleuritis and highlights the typical challenges encountered in these cases.

Myocardial Infarction With Non-obstructive Coronary Arteries: An Updated Overview of Pathophysiology, Diagnosis, and Management.

Myocardial infarction with non-obstructive coronary arteries (MINOCA) refers to acute myocardial infarction with normal or near-normal coronary arteries. The MINOCA is a heterogeneous group of conditions, and possible etiologies are coronary artery spasm, spontaneous coronary artery dissection, coronary thromboembolism, coronary plaque disruption, coronary microvascular dysfunction, supply and demand mismatch. It is more common in young adults, with women having a higher chance of getting MINOCA than men. Considering MINOCA as a clinically dynamic working diagnostic that needs further investigation rather than a "true" diagnosis is proposed. Optical coherence tomography (OCT), intravenous ultrasound (IVUS), cardiac MRI may be required to stratify the underlying mechanism. Due to the lack of evidence-based literature and prospective randomized controlled studies, therapeutic management is limited. Consequently, the strategy is patient-specific. The prognosis of MINOCA patients remains unclear and depends upon the underlying etiology. This article aims to review the literature about various aspects of MINOCA, including pathophysiology, diagnosis, prognosis, and treatment.

Successful Debulking of Tricuspid Valve Vegetation Using Suction Filtration and Veno-Venous Bypass.

Tricuspid valve endocarditis with recurrent septic pulmonary emboli is an indication for surgery. In this report, we present a case of right-sided infective endocarditis (RSIE) in a female patient with a history of intravenous drug use (IVDU). The patient was admitted with multiple chief complaints of fatigue, chills, fever, cough, chest pain, and shortness of breath. She was found to have a large 1.8 cm (W) x 2.4 cm (L) mobile tricuspid valve vegetation on transthoracic echocardiogram (TTE). Despite being on appropriate antibiotics, the patient failed to improve clinically. Cardiothoracic surgery (CTS) evaluated the patient for surgical management of infective endocarditis (IE) given the size of vegetation, persistent bacteremia, and clinical deterioration. However, the risk/benefit ratio for open-heart surgery was high, given the history of active IVDU and hemodynamic instability. The patient underwent percutaneous extraction of the vegetation using suction filtration and veno-venous bypass and her condition significantly improved clinically afterward. We discuss the importance of suction filtration and veno-venous bypass in managing tricuspid valve endocarditis as an alternative in patients who are not ideal candidates for surgery and the need for more evidence regarding its effectiveness compared to surgery.

Serotonin Syndrome Precipitated by the Use of Cocaine and Fentanyl.

Serotonin syndrome (SS) is a condition that occurs following the administration of serotonergic drugs. The syndrome is classically associated with the simultaneous administration of two serotonergic agents. Herein, we present a unique case of SS precipitated by cocaine and fentanyl in conjunction with previously prescribed oxycodone/paracetamol, trazodone, and mirtazapine. The patient was brought to the hospital with chief complaints of altered mental status, abdominal pain, nausea, and vomiting. The patient used her friend's fentanyl patch, and her urine drug screen was positive for cocaine. She was intubated and admitted to the intensive care unit for a low Glasgow Coma Scale score of 6 and autonomic instability. All the inciting agents were stopped, supportive treatment was given, and the patient was sedated with benzodiazepines and propofol. She received cyproheptadine, and the patient was extubated and clinically improved over the next 24 hours. Cocaine and fentanyl are not classically associated with SS. We did not encounter any cases where SS was precipitated by the combined use of cocaine and fentanyl in patients taking psychotropic medications during our literature review. This case report underlines the association of SS with cocaine and fentanyl. SS should be suspected in patients using cocaine and fentanyl or any other substance of abuse along with psychotropic agents.

Hyperthyroidism Presenting With Mania and Psychosis: A Case Report.

Graves' disease accounts for one of the most common causes of thyrotoxicosis. Most patients with Graves' disease present with classic signs and symptoms of hyperthyroidism. Psychosis and mood symptoms secondary to hyperthyroidism are rare. Here we report the case of a 37-year-old male with a history of Graves' disease with poor medication adherence who presented to the emergency department with psychotic features and hyperexcitability. He had excessive agitation, paranoia, and hyperactivity requiring restraints. He also endorsed insomnia and weight loss. He was admitted to the inpatient unit, and laboratory investigations were significant for a low thyroid-stimulating hormone, and elevated T3, T4, thyroid-stimulating antibodies, and thyroid peroxidase antibodies. The initial assessment was a primary psychiatric illness. The patient never had a personal or family history of psychiatric illness. Psychiatry and endocrinology were consulted for further recommendations. The patient was started on methimazole 30 mg, propranolol 100 mg, and hydrocortisone 100 mg, which resolved his symptoms.
