Differential Pulmonary Rehabilitation Outcomes in Patients With and Without COPD: ROLE OF GENDER.

PURPOSE: Individuals with all forms of pulmonary disease are referred for pulmonary rehabilitation. This study examines pulmonary rehabilitation outcomes between individuals with chronic obstructive lung disease (COPD) and non-COPD disease and the impact of gender. METHODS: This is a retrospective study at a tertiary center. The primary endpoint was the difference in 6-min walk test distance. Secondary measurements included treadmill and NuStep minutes; biceps curls and front arm raises load; quality of life measured by the St George's Respiratory Questionnaire; and University of California San Diego-Shortness of Breath Questionnaire (UCSD-SOBQ) scores. RESULTS: Eighty patients were included: 38 men (23 COPD, 15 non-COPD) and 42 women (31 COPD, 11 non-COPD). There was a statistically significant improvement in 6-min walk test distances pre- to post-pulmonary rehabilitation for all participants, P = .0003. Although both the COPD and non-COPD groups demonstrated overall improvement (P < .0004 and P = .02, respectively), subgroup analysis showed no statistically significant change in the non-COPD group when divided by gender. There was a significant statistical improvement in lower and upper extremity strength in all participants. Only women with COPD showed a statistically significant improvement with respect to overall quality of life as measured by St. George's Respiratory Questionnaire (P = .01). Women showed significant improvement in their depression score, as well as a trend toward improvement in the University of California San Diego-Shortness of Breath Questionnaire, while only men with COPD showed any improvement in their sleep quality measured by the Pittsburgh Sleep Quality Index. CONCLUSIONS: Pulmonary rehabilitation results in different but improved outcomes regardless of gender or disease state.

Acute Fibrinous and Organizing Pneumonia Associated With Allogenic Hematopoietic Stem Cell Transplant Successfully Treated With Corticosteroids: A Two-Patient Case Series.

Acute fibrinous and organizing pneumonia (AFOP) is an extremely rare, relatively new, and distinct histological pattern of acute lung injury characterized predominately by the presence of intra-alveolar fibrin and associated organizing pneumonia. AFOP may be idiopathic or associated with a wide spectrum of clinical conditions. It has a variable clinical presentation from mild respiratory symptoms to that similar to the acute respiratory distress syndrome. Currently there is no consensus on treatment, and corticosteroids previously were of unclear benefit. To date, there are less than 40 cases of AFOP reported in the literature and only one has been linked to hematopoietic stem cell transplantation. Here we report the first case series of 2 patients who developed AFOP following allogenic stem cell transplant that were successfully treated with high-dose corticosteroids.

A Rare but Reversible Cause of Hematemesis: "Downhill" Esophageal Varices.

"Downhill" varices are a rare cause of acute upper gastrointestinal bleeding and are generally due to obstruction of the superior vena cava (SVC). Often these cases of "downhill" varices are missed diagnoses as portal hypertension but fail to improve with medical treatment to reduce portal pressure. We report a similar case where recurrent variceal bleeding was initially diagnosed as portal hypertension but later found to have SVC thrombosis presenting with recurrent hematemesis. A 39-year-old female with history of end-stage renal disease presented with recurrent hematemesis. Esophagogastroduodenoscopy (EGD) revealed multiple varices. Banding and sclerotherapy were performed. Extensive evaluation did not show overt portal hypertension or cirrhosis. Due to ongoing bleeding requiring resuscitation, she underwent internal jugular (IJ) and SVC venogram in preparation for transjugular intrahepatic portosystemic shunt (TIPS), which demonstrated complete IJ and SVC occlusion. She underwent balloon angioplasty with stent placement across SVC occlusion with complete resolution of her varices and resolved hematemesis. "Downhill" varices are extremely rare, though previously well described. Frequently, patients are misdiagnosed with underlying liver disease. High index of suspicion and investigation of alternative causes of varices is prudent in those without underlying liver diseases. Prompt diagnosis and appropriate intervention can significantly improve morbidity and mortality.

Temporary Endobronchial Stent as a Bridge to Corrective Surgery For Severe Kyphoscoliosis-associated Central-Airway Extrinsic Compression.

Kyphoscoliosis is known to compromise lung function, with the primary mechanism being reduced chest wall compliance with a resultant restrictive pulmonary physiology. Severe scoliosis can also cause extrinsic compression of the central airways, leading to recurrent respiratory infections, lobar atelectasis, and potentially acute respiratory failure. Definitive therapy is corrective surgery of the spine. However, patients with severe scoliosis are at a potentially high risk of perioperative pulmonary complications. To our knowledge, we report the first successful use of retrievable endobronchial stents as a bridge to corrective surgery for kyphoscoliosis-associated complete central-airway extrinsic compression in a patient who was considered as too high risk for surgical correction due to her respiratory status. After surgery, the stents were removed and our patient experienced sustained improvement in pulmonary function and the clinical respiratory status.

Drug reaction with eosinophilia and systemic symptoms syndrome (DRESS) syndrome associated with azithromycin presenting like septic shock: a case report.

INTRODUCTION: Drug reaction with eosinophilia and systemic symptoms syndrome is a potentially life-threatening cutaneous hypersensitivity reaction characterized by extensive mucocutaneous eruption, fever, hematologic abnormalities including eosinophilia and/or atypical lymphocytosis, and extensive organ involvement. The drugs most often responsible for causing drug reaction with eosinophilia and systemic symptoms syndrome are anticonvulsants, antimicrobial agents and antipyretic or anti-inflammatory analgesics. Although azithromycin is widely prescribed in clinical practice, serious cutaneous reactions from this agent have been rarely described. We report the first adult case of drug reaction with eosinophilia and systemic symptoms syndrome associated with azithromycin. CASE PRESENTATION: A 44-year-old previously healthy Caucasian man with history of tobacco use presented to his primary care physician with fever and productive cough. He was prescribed azithromycin, promethazine hydrochloride and dextromethorphan hydrobromide syrup. One week later, he developed a blistering erythematous rash over both hands, which over the next two weeks spread to involve nearly his entire body surface, sparing only his face. He was admitted to an outside hospital with signs of systemic inflammatory response syndrome and severe sepsis, presumably from a skin infection. Despite aggressive therapy he deteriorated, with worsening diffuse erythema, and was transferred to our institution. He developed multiple organ failure requiring ventilatory and hemodynamic support. Pertinent laboratory studies included a leukocytosis with a white blood cell count of 17.6 × 10(9)/L and 47% eosinophils. A skin biopsy showed evidence of spongiotic lichenoid dermatitis with eosinophils and neutrophils, compatible with a systemic drug-induced hypersensitivity reaction. Our patient was started on high-dose steroids and showed dramatic improvement within 48 hours. CONCLUSIONS: We report the first adult case of drug reaction with eosinophilia and systemic symptoms syndrome associated with azithromycin exposure. Clinicians should be aware of this potentially devastating complication from this commonly prescribed medication.
