A Unique Presentation of Pulmonary Langerhans Cell Histiocytosis
Varun Srivatsav, MD and Kelsey Tallon, MD
Article Type: Case Report | First Published: December 10, 2021
Pulmonary langerhans cell histiocytosis (PLCH) is a diffuse lung disease that primarily affects young adults, with cigarette smoking playing a significant role in developing the disease. Patients with PLCH present with characteristic CT chest findings of small irregular nodules and upper zone cysts. Previously, larger nodules greater than 10 mm and cavitation have only been reported a few times in the literature. We describe the case of a 69-year-old male who presented with dyspnea, non-producti...
Pneumonia Due To Stenotrophomonas maltophila in the Immunocompetent Patient: A Case of Environmental Exposure
Article Type: Letter to Editor | First Published: December 10, 2021
Stenotrophomonas maltophilia is a multi-resistant gram-negative bacterium, an opportunistic agent generally associated with nosocomial infections, particularly in immunocompromised patients, being usually found in the intensive care setting. However, its prevalence in patients without predisposing risk factors is very rare. We have identified and successfully treated a healthy, immunocompetent patient who developed a community acquired severe S. maltophilia pneumonia. We report the case of a 24-...

A middle-aged African American male with a history of stage 2 chronic kidney disease status post double kidney transplant was admitted after developing symptoms of respiratory infection during the peak of COVID-19. The patient rapidly developed acute hypoxemic respiratory failure. Differentials for the patient included COVID-19, opportunistic infection such as mycoplasma, and legionella. During the admission, the patient had numerous infectious disease screening tests run including a COVID-19 te...

There are variable long-term pulmonary outcomes of children with congenital diaphragmatic hernia (CDH). Diagnostic modalities evaluating pulmonary function can be limited by patient compliance. Pulmonary perfusion scintigraphy is a diagnostic tool to evaluate lung development in younger children. Presence of a hernia sac is known to correlate with less severe disease but little has been reported on any correlation with lung size and function. The purpose of this study was to evaluate the relatio...
Streptococcus Constellatus Empyema Presenting With Undulant Fever Pattern- A Case Report and Literature Review

Streptococcus anginosus group (SAG), or milleri group streptococci (MGS), is an uncommon group of bacteria that has been increasingly affecting the adult population. It is an interesting organism in that it is intensely pyogenic when pathogenic-much in the same character as Staphylococcus aureus. SAG includes three species: Streptococcus anginosus, Streptococcus intermedius, and Streptococcus constellatus. Members of the SAG are usually part of the indigenous oral, gastrointestinal, and genitour...
