Hot tub lung is described as an acute pulmonary illness that is characterized by fever, dyspnea and interstitial nodular infiltrates. Although not entirely clear, the etiology may be a hypersensitivity pneumonitis, an infection secondary to Mycobacterium avium intracellulare (MAC), or possibly both. Herein we describe the most well-characterized physiologic, radiographic, and functional recovery from hot tub lung reported in the literature to date. Pulmonary function testing and CT scans of the chest were obtained after each therapeutic intervention, and the patient had the most dramatic improvement with simply avoiding the hot tub. Prednisone therapy offered minimal further improvement while anti-MAC therapy provided no further improvement. These results are suggestive of a hypersensitivity pneumonitis rather than an infectious etiology.

Bisphosphonates are the most widely used medication to treat osteoporosis. Recent reports have documented an association between chronic bisphosphonate use and femoral insufficiency fractures. This article describes an 84-year-old woman with a diagnosis of osteoporosis treated with bisphosphonate medications for 9 years. She presented with left groin pain, and magnetic resonance imaging revealed a subtrochanteric femoral stress fracture. Operative and nonoperative management was discussed with the patient, and she chose to undergo prophylactic intramedullary nailing of the left femur. Six months postoperatively, she was asymptomatic and ambulating without assistive devices.This article describes successful management of a bisphosphonate-related femoral insufficiency fracture. The presence of groin or thigh pain in a patient taking bisphosphonates should alert the physician to the possibility of insufficiency fracture of the proximal femur, and plain radiographs should be obtained. If these radiographs show lateral cortical thickening, consideration should be given to prophylactic intramedullary femoral nailing. The risks and benefits of prophylactic fixation vs conservative management should be discussed with the patient. A recent series showed a high failure rate with conservative treatment of these fractures. A dialogue with the primary care physician should be initiated to determine the necessity of bisphosphonate therapy, and, if deemed necessary, an alternative class of medications should be considered.

This previously undescribed ligament is a robust structure, present on at least one side in over 80% of the individuals studied. When present, the ligament creates a narrow interval between the ligament and the first rib that the T1 ventral ramus traverses before crossing the first rib superiorly and contributing to the inferior trunk of the brachial plexus. Although the actual clinical significance has not been demonstrated, this ligament may represent another entrapment site for the T1 ventral ramus.
