Surveillance of the colorectal cancer disparities among demographic subgroups: a spatial analysis.
The literature suggests that colorectal cancer mortality in Texas is distributed inhomogeneously among specific demographic subgroups and in certain geographic regions over an extended period. To understand the extent of the demographic and geographic disparities, the present study examined colorectal cancer mortality in 15 demographic groups in Texas counties between 1990 and 2001. ⋯ Health disparities of colorectal cancer mortality continue to exist in Texas demographic subpopulations. Health education and intervention programs should be directed to the at-risk subpopulations in the identified regions.

Case ReportsRenal artery stenting for intimal flap injury in a 2-year-old child after blunt abdominal trauma.
Injury to the renal vasculature is an uncommon occurrence in the setting of blunt abdominal trauma. The authors report the case of a 2-year-old girl who developed occlusion from an intimal flap in a renal artery (grade IV renal injury) after blunt abdominal trauma that was treated with a stent placement. ⋯ However, several months after the procedure, the patient developed stenosis within the stent and ultimately required a nephrectomy. To the authors' knowledge, this is the first report of percutaneous management of an acute intimal flap in a renal artery in a 2-year-old.

Case ReportsA woman with cough, fever, and micronodular infiltrates on chest radiograph.
Hot tub lung is a form of hypersensitivity pneumonitis (HP) reported to be associated with exposure to large aerosolized inocula of Mycobacterium avium complex (MAC). Although the pathogenesis of the disease is still poorly understood, the pathology of MAC-related HP can be similar to that of sarcoidosis, with well-formed granulomas. We describe a patient with HP featuring well-formed granulomas on transbronchial biopsy specimens, a finding believed to be unique to MAC-related HP, also referred to as "hot tub lung".

Case ReportsSpontaneous pneumomediastinum due to achalasia: a case report.
Spontaneous pneumomediastinum (SPM) is a rare and benign clinical entity characterized by free air around mediastinal structures. Precipitating factors include violent cough, asthma, inhalational drugs, labor and exercise. We report a case of SPM due to achalasia which to the best of our knowledge, has never been reported. ⋯ Air tracks along the mediastinal spaces cause SPM. In our patient, there was no evidence of esophageal perforation. Tension pneumomediastinum and pneumothorax are complications of SPM.
