Many critically ill patients who die will do so after a decision has been made to withhold/withdraw life-sustaining therapy. The objective of this study was to document the characteristics of ICU patients with a decision to withhold/withdraw life-sustaining treatment, including the types of supportive treatments used, patterns of organ dysfunction, and international differences, including gross national income (GNI).

The mechanism by which various classes of medication reduce COPD exacerbation risk remains unknown. We hypothesized a correlation between reduced exacerbation risk and improvement in airway patency as measured according to FEV1.

Clofazimine is an antimicrobial agent that has activity in vitro against mycobacteria. Increasingly, it has been used for the treatment of nontuberculous mycobacteria (NTM), despite limited data supporting its use in this setting. The objective of this study was to evaluate the safety, tolerability, and clinical outcomes associated with clofazimine in patients with NTM infection.

A 33-year-old woman of Latin American origin was referred to our department by her primary care physician for a left lower lobe mass, which was incidentally found on a CT scan of her abdomen. The patient had complaints of abdominal pain for which she underwent imaging of her abdomen. Review of systems was negative for any respiratory complaints, and she denied any history of cigarette smoking or recreational drug use.

A woman in her 30s presented to the ED with a 3-month history of shortness of breath on exertion, dry cough, and pleuritic chest pain. A month ago, the patient was seen at an internal medicine clinic and was found to have a right pleural effusion. A thoracentesis revealed straw-colored fluid, a total nucleated cell count of 1,260 × 106/L, and a differential with neutrophils of 0.15, lymphocytes of 0.55, macrophages/monocytes of 0.19, and eosinophils of 0.10. Fluid cytology and culture were negative. The patient was presumed to have a parapneumonic effusion and treated empirically with antibiotics. However, she continued to have progressive symptoms, prompting her current visit to the ED. The patient was diagnosed with stage IIIB invasive cervical squamous cell carcinoma (SCC) approximately 7 months ago. MRI of the pelvis demonstrated a cervical mass with invasion of the right parametrial fat, but there was no evidence of uterine, vaginal, or lymph node involvement. A CT scan of the chest, abdomen, and pelvis was negative for distant metastases. The patient completed treatment with external beam radiation therapy and cisplatin chemotherapy 6 months ago. Three weeks prior to presentation to the ED, a repeat MRI pelvis showed no evidence of tumor progression and features consistent with posttreatment fibrotic changes.

A 61-year-old woman presented for outpatient evaluation of a 1-week history of fever and upper respiratory symptoms. She denied tobacco use, weight loss, hemoptysis, chronic cough, or recent travel and was in otherwise good health. Her medical history was insignificant except for her chronic hoarseness from a prior laryngeal disease. She denied any worsening hoarseness or any other vocal changes. She did report a positive family history of squamous cell lung cancer in her father.
