Maltoma veiled in the lung-a rare case of pulmonary and gastric maltoma.

Mucosa associated lymphoid tissue (MALT) is a type of B-cell lymphoma that is commonly observed in the gastrointestinal site, most frequently occurring in the stomach. However, the incidence of this type of lymphoma in the respiratory tract is very uncommon. We report a case of this rare clinical entity in a patient who presented with non-symptomatology and was diagnosed with pulmonary MALT lymphoma (pMALToma).

COPD Maintenance Pharmacotherapy.

Chronic obstructive pulmonary disease (COPD) is currently the fourth leading cause of death worldwide and will likely be the third most common cause by the end of 2020. It is felt to be caused by repetitive noxious stimuli to the lung, most commonly from smoking, with persistent symptoms of cough, wheeze, and shortness of breath. Most patients will have these baseline symptoms, with periodic flare-ups known as exacerbations. This article focuses on pharmacological therapy in a stable COPD patient. Pharmacological treatment of a stable COPD patient focuses on minimizing symptoms, improving exercise tolerance, and preventing exacerbations. Nonpharmacological management of stable COPD, smoking cessation, and treatment of exacerbations are covered in other sections.

Comorbidities Associated With Chronic Obstructive Pulmonary Disease.

Chronic obstructive pulmonary disease or COPD is characterized by airflow obstruction, causing respiratory symptoms. There are treatments available for COPD; however, COPD has significant extrapulmonary effects, including well-recognized ones as cardiovascular disease and often underdiagnosed ones as osteoporosis. It is imperative to be aware of these comorbidities to optimize COPD patient care.

Health Care Workers' Challenges in the Care of a COVID-19 Patient.

The COVID-19 pandemic has introduced us to new challenges with personal protective equipment, long shifts, and changes in regular routines. This has placed a tremendous stress on health care workers. This article defines the various health care worker challenges, both at the bedside and on a personal front. Therapeutic strategies are discussed.

Complications and Outcomes of Acute Respiratory Distress Syndrome.

Acute respiratory distress syndrome (ARDS) is a disease associated with both short- and long-term complications. Acute complications include refractory respiratory failure requiring prolonged dependence on mechanical ventilation and the subsequent need for tracheostomy and gastrostomy tubes, protracted immobilization, and lengthy stays in the intensive care unit resulting in delirium, critical illness myopathy, and polyneuropathy, as well as secondary nosocomial infections. Chronic adverse outcomes of ARDS include irreversible changes such as fibrosis, tracheal stenosis from prolonged tracheostomy tube placement, pulmonary function decline, cognitive impairment and memory loss, posttraumatic stress disorder, depression, anxiety, muscle weakness, ambulatory dysfunction, and an overall poor quality of life. The degree of disability in ARDS survivors is heterogeneous and can be evident even years after hospitalization. Although survival rates have improved over the past 4 decades, mortality remains significant with rates reported as high as 40%. Despite advancements in management, the causes of death in ARDS have remained relatively unchanged since the 1980s with sepsis/septic shock and multiorgan failure at the top of the list.

Prone Positioning in ARDS.

Adult respiratory distress syndrome (ARDS) is a clinical entity characterized by hypoxemic respiratory failure in the setting of noncardiogenic pulmonary edema. It is associated with significant morbidity and mortality. Prone positioning is a beneficial strategy in patients with severe ARDS because it improves alveolar recruitment, ventilation/perfusion (V/Q) ratio, and decreases lung strain. The outcome is improved oxygenation, decreased severity of lung injury, and, subsequently, mortality benefit. In this article, we discuss the physiology of prone positioning on chest mechanics and V/Q ratio, the placement and maintenance of patients in the prone position with use of a prone bed and the current literature regarding benefits of prone positioning in patients with ARDS.

DKA-Induced Takotsubo Cardiomyopathy in Patient with Known HOCM.

The first published case of Diabetic Ketoacidosis-induced Takotsubo cardiomyopathy was in 2009. Our patient is the 1st reported case of Diabetic Ketoacidosis- (DKA-) induced Takotsubo cardiomyopathy (TC) in a patient with known hypertrophic cardiomyopathy (HOCM) in the United States. In the literature, there are only two examples linking DKA to TC; however, this report focuses on the biochemical and physiological causes of TC in a patient with known HOCM and new-onset DKA. TC in previously diagnosed HOCM poses particular complications. With the above patient's baseline outflow tract obstruction due to septal hypertrophy, the acute reduction in EF due to TC resulted in transient drop in brain perfusion and, therefore, syncope.
