Low attenuation areas in necrotizing soft tissue infection.

Necrotizing Soft Tissue Infection can be challenging to differentiate from abscesses based on computed tomography imaging findings only, so it is crucial to perform surgical debridement as early as possible.

Refractory gastric ulcer due to undisclosed use of topical diclofenac epolamine patches.

BACKGROUND: Topical forms of nonsteroidal anti-inflammatory drugs (NSAIDs) have been created to lessen systemic adverse effects. In general, they are believed to be well tolerated and appropriate for use as an over-the-counter (OTC) drug. CASE PRESENTATION: A 68-year-old woman visited our clinic due to tarry stool. The patient reported multiple episodes of recurrent bleeding from a gastric ulcer for 2 months and was treated with endoscopic hemostatic clipping. The patient disclosed she had been using a large number of diclofenac patches for more than 3 months. The patient was treated conservatively by discontinuation of diclofenac patches and treatment with a proton pump inhibitor and omeprazole. CONCLUSION: In conclusion, inappropriate use of topical NSAID patches can be a cause of peptic ulcer bleeding. Patients reporting multiple episodes of recurrent bleeding from a gastric ulcer should be questioned, particularly about the use of OTC medications that might include topical NSAID patches.

A biomechanics analysis of the judo osoto-gari technique: comparison of black belt and white belt judokas.

The purpose of this study was to determine biomechanical factors for the effective execution of the osoto-gari technique by comparing differences between black belt and white belt judokas. Twenty-two male judokas (12 black belts; 10 white belts) performed osoto-gari, and the motion data were recorded using a Mac3D motion analysis system (250 Hz). The peak angular momentums of the trunk and leg of the uke were larger in the black belts than in the white belts, suggesting that the black belts rotated the uke's body more effectively than the white belts. During the swing phase, the peak angular velocities of the arms and trunk twist in the black belts were larger compared to the white belts. During the throwing phase, the black belts had substantially greater peak angular velocities of the arms, upper torso, and trunk twist. Additionally, the timing of the peak value of the upper torso and trunk twist of the black belts was closer to sweeping leg contact than that of the white belts. The results can provide coaches with suggestions for improving training protocol design when teaching osoto-gari and for helping novices more efficiently master the technique.
