Cocaine is one of the most commonly abused drugs in the United States. Ingestion of cocaine may result in a wide array of disease processes due to its stimulant properties, contaminants, or to downstream effects, such as myo- cardial infarction, stroke, or cardiac arrest. Pulmonary complaints are common in patients seeking treatment for cocaine-associated medical problems and include acute eosinophilic pneumonia, pneumothorax, pneumomediastium, diffuse alveolar hemorrhage (DAH), pulmonary hypertension and granulomatosis. We present a case of DAH due to cocaine abuse and rapid resolution with mechanical ventilation and supportive care.

Background: Acute lung injury (ALI) is a disordered pulmonary disease characterized by acute respiratory insufficiency with tachypnea, cyanosis refractory to oxygen and diffuse alveolar infiltrates. Despite increased research into ALI, current clinical treatments lack effectiveness. Tetramethylpyrazine (TMP) has shown potential in ALI treatment, and understanding its effects on the pulmonary microenvironment and its underlying mechanisms is imperative.

There is limited knowledge on diffusing capacity in scoliosis patients. It remains to be determined if impaired pulmonary diffusing capacity is mostly influenced by reduced alveolar-capillary membrane diffusing capacity (D), reduced pulmonary capillary blood volume (V) or both. This study aims to report findings from dual test gas pulmonary diffusing capacity for carbon monoxide and nitric oxide (D) with quantification of pulmonary diffusing capacity for carbon monoxide corrected for haemoglobin with a five s breath-hold (D) and nitric oxide with a five s breath-hold (D), D and V.

This case involves a 21-year-old male healthcare student with a medical history of HIV-1 infection for two years and anxiety disorder. He presented to the emergency department with hemoptysis and dyspnea of sudden onset. A thoracic CT scan revealed multiple bilateral nodular ground-glass opacities suggestive of diffuse alveolar hemorrhage (DAH).

A 76-year-old man with a past occupational history as a firefighter and construction worker presented at an urgent care center with signs and symptoms of chronic dry cough, exertional dyspnea, and fatigue. His initial chest X-ray showed interstitial thickening in the middle and lower lobes with pulmonary infiltrates bilaterally. The patient was treated with an outpatient course of antibiotics.

typically causes mild respiratory infections but can rarely lead to severe complications. We report a case of a 43-year-old immunocompetent male who presented with progressive dyspnea and respiratory failure with bilateral pulmonary infiltrates, refractory to outpatient treatment with azithromycin, ceftriaxone, and levofloxacin. Bronchoscopy revealed multiple white plaques in the trachea and diffuse alveolar hemorrhage.
