A case of isolated splenic tuberculosis.

There are few cases of isolated splenic tuberculosis reported in the literature internationally, and nearly none from western medical centers. The incidence of tuberculosis has declined in the United States since the 1950s, with 11,585 reported cases in 2009, 21% of which were exclusively extrapulmonary. Splenic tuberculosis occurs mostly as part of miliary tuberculosis in immunocompromised patients. Isolated splenic tuberculosis is extremely rare, particularly in the immunocompetent patient. Patients susceptible to acquiring splenic tuberculosis usually have one of the following risk factors: immunosuppression, preceding pyogenic infections, splenic abnormalities, prior trauma to the spleen, sickle cell disease and other hemopathies, and in the immunocompetent patient another body site infected by M. tuberculosis. In this report we present the case of a young immunocompetent male with no other significant past medical history with isolated splenic tuberculosis.

Lung volume reduction surgery since the National Emphysema Treatment Trial: study of Society of Thoracic Surgeons Database.

OBJECTIVES: The National Emphysema Treatment Trial demonstrated that lung volume reduction surgery is an effective treatment for emphysema in select patients. With chronic lower respiratory disease being the third leading cause of death in the United States, this study sought to assess practice patterns and outcomes for lung volume reduction surgery on a national level since the National Emphysema Treatment Trial. METHODS: Aggregate statistics on lung volume reduction surgery reported in the Society of Thoracic Surgeons Database from January 2003 to June 2011 were analyzed to assess procedure volume, preoperative and operative characteristics, and outcomes. Comparisons with published data from the National Emphysema Treatment Trial were made using chi-square and 2-sided t tests. RESULTS: In 8.5 years, 538 patients underwent lung volume reduction surgery, with 20 to 118 cases reported in the Society of Thoracic Surgeons Database per year. When compared with subjects in the National Emphysema Treatment Trial, subjects in the Society of Thoracic Surgeons Database were younger (P < .001), a larger proportion underwent the procedure thoracoscopically (P < .001), and forced expiratory volume in 1 second was 31% versus 28% of predicted (P < .001). When mortality was compared between subjects in the Society of Thoracic Surgeons Database and all subjects in the National Emphysema Treatment Trial randomized to surgery, there were no significant differences. However, mortality was 3% higher in subjects in the Society of Thoracic Surgeons Database when compared with the non-high-risk National Emphysema Treatment Trial subset (P = .005). CONCLUSIONS: This study demonstrates the importance of patient selection and the need to develop consensus on appropriate benchmarks for mortality rates after lung volume reduction surgery. It underscores the need for dedicated centers to increasingly address the heavy burden of chronic lower respiratory disease in the United States in a multidisciplinary fashion, particularly for preoperative evaluation and postoperative management of emphysema.

Management of ampullary carcinoid tumors with pancreaticoduodenectomy.

A 66 year old female was found to have an ampullary mass on endoscopic examination. A pancreaticoduodenectomy was performed and the pathology was consistent with carcinoid tumor. Carcinoid tumors of the ampulla of Vater are rare tumors of the gastrointestinal tract, accounting for 0.3-1% of gastrointestinal carcinoids. Management of ampullary carcinoid tumor with pancreaticoduodenectomy is in accordance with current recommendations.
