A 77-year old female is presented with volvulus of the ascending colon due to torsion around a vitelline duct remnant. Symptoms were mild and intermittent. Roentgenograms are presented which demonstrated this lesion preoperatively. At surgery the ascending colon was found to be twisted around a fibrous band extending from the umbilicus to the ileum. 相似文献

Biological markers form an important part of the decision-makingprocess for regranting of driving licences in France. A majorcriterion in this respect is the need to distinguish betweenacute alcohol use and chronic abuse by applicants. Current markersreflect more hepatic damage than alcohol consumption and thisstresses the need for more reliable markers. 相似文献

Synovial fluid from 16 normal subjects was compared with thatfrom 149 patients with a variety of rheumatic disorders. Normalfluid had fewer cells and a lower content of ß-glucuronidasethan osteoarthritic samples. Particles, including occasionalbirefringent crystals, were seen in normal fluids as well aspathological samples. Alizarin red staining particles (presumedto contain apatite) were seen in all diagnostic groups; theirnumbers showed some correlation with radiological calcificationin and around the joints and with a hypertrophic subchondralbone response. Lactate levels were highest in septic arthritis.No assay showed disease specificity. KEY WORDS: Synovial fluid analysis 相似文献

Isthmus conduction block, demonstrated with the use of multipolar catheter recordings, is considered the preferred endpoint for ablation of type I atrial flutter. This study investigated the feasibility of using recordings from the His and coronary sinus (CS) to document isthmus conduction block. Isthmus conduction block was produced with linear radiofrequency (RF) ablation in 27 patients with type I atrial flutter. In 13 patients (group I), RF was delivered until bidirectional isthmus conduction block was demonstrated with multipolar Halo catheter recordings. In 14 patients (group II), RF was delivered during pacing from the lateral isthmus at 600 ms until a reversal in activation of the proximal CS and His occurred. At this point, data from the Halo recordings were reviewed to see if reversal correlated with conduction block; if not, further ablation was performed until block was demonstrated. The initial reversal in His and CS activation during RF energy delivery correlated with isthmus block in only 4 (28.6%) of 14 patients in group II. Additional RF delivery produced isthmus block in the other ten patients resulting in a further increase in the St-CS interval of 35 ± 20 ms. A His-CS interval of at least -40 ms signified isthmus block with a sensitivity and specificity of 48% and 100%, respectively. Reversal in His-CS activation during pacing from the lateral margin of the isthmus is not specific for the creation of isthmus block. While activation of the proximal CS bipole > 40 ms after activation of the His appears specific for isthmus block, the low sensitivity of this finding limits its clinical use. 相似文献
