A rare case of miliary tuberculosis accompanying perihepatitis

Perihepatic capsulitis is associated with various diseases, such as Fitz-Hugh-Curtis syndrome, systemic lupus erythematosus, perforated cholecystitis, perforated hepatic abscess, and tuberculous peritonitis. Miliary tuberculosis is present in about 2% of all reported cases of tuberculosis and is characterized by the widespread millet-like hematogenous dissemination of Mycobacterium tuberculosis. We describe a 24-year-old virgin patient presenting with right upper quadrant and costovertebral angle pain. Diffuse perihepatic capsular enhancement was observed in abdominal computed tomography scans. Chest radiography showed miliary tuberculosis, and a polymerase chain reaction hybridization assay of sputum revealed the presence of M. tuberculosis. Symptoms improved after administering anti-tuberculosis medications. This report describes a rare case of miliary tuberculosis accompanying perihepatitis.

Exploratory, cognitive, and depressive-like behaviors in adult and pediatric mice exposed to controlled cortical impact

OBJECTIVE: Sequelae of behavioral impairments associated with human traumatic brain injury (TBI) include neurobehavioral problems. We compared exploratory, cognitive, and depressive-like behaviors in pediatric and adult male mice exposed to controlled cortical impact (CCI).METHODS: Pediatric (21 to 25 days old) and adult (8 to 12 weeks old) male C57Bl/6 mice underwent CCI at a 2-mm depth of deflection. Hematoxylin and eosin staining was performed 3 to 7 days after recovery from CCI, and injury volume was analyzed using ImageJ. Neurobehavioral characterization after CCI was performed using the Barnes maze test (BMT), passive avoidance test, open-field test, light/dark test, tail suspension test, and rotarod test. Acutely and subacutely (3 and 7 days after CCI, respectively), CCI mice showed graded injury compared to sham mice for all analyzed deflection depths.RESULTS: Time-dependent differences in injury volume were noted between 3 and 7 days following 2-mm TBI in adult mice. In the BMT, 2-mm TBI adults showed spatial memory deficits compared to sham adults (P < 0.05). However, no difference in spatial learning and memory was found between sham and 2-mm CCI groups among pediatric mice. The open-field test, light/dark test, and tail suspension test did not reveal differences in anxiety-like behaviors in both age groups.CONCLUSION: Our findings revealed a graded injury response in both age groups. The BMT was an efficient cognitive test for assessing spatial/non-spatial learning following CCI in adult mice; however, spatial learning impairments in pediatric mice could not be assessed.
