Migraine affects ∼15% of the world's population greatly diminishing their quality of life. Current preventative treatments are effective in only a subset of migraine patients, and although cannabinoids seem beneficial in alleviating migraine symptoms, central nervous system side effects limit their widespread use. We developed peripherally restricted cannabinoids (PRCBs) that relieve chronic pain symptoms of cancer and neuropathies, without appreciable central nervous system side effects or tolerance development. ⋯ Peripherally restricted cannabinoid pretreatment prevented all behavioral and biochemical correlates of allodynia and latent sensitization. Importantly, long-term PRCB treatment alone did not produce any behavioral or biochemical signs of sensitization. These data validate peripheral cannabinoid receptors as potential therapeutic targets in migraine and medication overuse headache.

A 58-year-old man presented to the ED with a 1-week history of progressive weight loss, generalized weakness, unsteadiness, and dizziness. In hospital, he experienced a witnessed episode of loss of consciousness with no observable respirations that lasted for 15 minutes. His arterial blood gas demonstrated hypercapnic respiratory failure, and he required mask ventilation and vasoactive medications. ⋯ The patient's medical history was pertinent for a diagnosis of prostatic carcinoma 3 years previously that was found to be castrate resistant. He had metastases to his hip, ribs, and thoracic spine. Previous treatments had included bicalutamide, docetaxel, and abiraterone; he was receiving leuprolide therapy on presentation.

A 66-year-old woman with a history of diabetes presented with an intermittent low-grade fever, cough, shortness of breath, and decreased activity tolerance over a 3-month period. She is a farmer, and denied a history of chronic pulmonary disease. Her only medical history was type 2 diabetes managed without medication. ⋯ An infection with mucormycosis was diagnosed through transbronchial biopsy. The patient was given nebulized amphotericin B along with concurrent IV liposomal amphotericin B for a total of 15 days. She experienced no significant improvement in symptoms during therapy and, in fact, developed worsening, progressive dyspnea.

A 34-year-old previously healthy man of Korean descent (height, 174 cm; weight, 47.4 kg) demonstrated dyspnea with cough and chest tightness. The patient had no relevant occupational exposures and no history of illicit drug or tobacco use. His medical history was notable for chronic sinus tachycardia of undetermined cause, hypertension, gout, glaucoma of the right eye, and a remote history of an intracranial malignancy 24 years prior treated with unspecified chemotherapy, craniotomy, and ventriculoperitoneal shunt placement. His active medications included diltiazem, candesartan, and colchicine as needed.

A 61-year-old man presented to the ED with fever, chills, cough, purulent sputum, and progressive shortness of breath for 7 days. The patient was an active smoker with at least 80 pack-year smoking history. He had no other medical or surgical history and was not on any medication at home.
