Abdominal infection with gas forming organisms may spread to the thigh & leg. We report a case of critically ill patient who presented to the emergency department with features suggestive of septic arthritis of the left hip. Assessment and further intervention revealed subcutaneous emphysema of the leg secondary to an infection of a previously asymptomatic staghorn calculus. X-ray of the abdomen showed a left renal stone and gas in the soft tissue planes of the left retroperitoneal space while X-ray of the left femur showed gas in the soft tissue planes of the left hip region and whole thigh with no bony or joint abnormality. Such case has not been reported in English literature before. Physicians and surgeons should be aware of this condition that could be fatal but curable by early intervention.展开更多

Failure to remove these spines or inability to remove them completely can lead to long-term squeal of pain and impaired function. Treatment methods include alternative medicine, LASER and surgery. We describe the surgical removal of 102 sea urchin spines from the foot of a 36-year-old man. The wounds healed completely. Although, he initially complained of a mild discomfort on weight bearing, the symptoms disappeared 2 weeks later.展开更多

MethodsThe PCR products of 4096 human genes were spotted onto a kind of chemical-material-coated-glass slides. The total RNAs were isolated from the tissues. Both the mRNAs from the degeneration and normal lumbar intervertebral disc in humans were reversely transcribed to the cDNAs, which used as the hybridization probes with the incorporations of fluorescent dUTP. The mixed probes were then hybridized to the cDNA microarray. After high-stringent washing, the cDNA microarray was scanned for the fluorescent signals and analyzed with computer image analysis. ResultsAmong the 4096 targets, there were 706 genes whose expression levels differed between the degeneration and normal lumbar intervertebral disc in all cases, comprising 298 up-regulated and 358 down-regulated ones. ConclusionDNA microarray technology is an effective technique in screening for differently expressed genes between the degeneration and normal lumbar intervertebral disc. Cell apoptosis plays an important role in the process of lumbar intervertebral disc degeneration.展开更多
