[Q]: Abstract: Definitive treatment of life-threatening hemorrhage associated with blunt pelvic fracture remains controversial. To elucidate this issue, we reviewed 538 consecutive patients admitted with acute pelvic fracture during a 5-year period. Injury mechanism was motor vehicular in 214 (40%), falls in 152 (28%), auto-pedestrian in 92 (17%), motorcycle in 46 (9%), crush in 26 (5%), and assault or skiing in eight (1%). Ninety-two (17%) of these patients required greater than 6 units of blood transfusion during the first postinjury day, and are the primary focus of this report. Twenty-five patients (28%) had unilateral anterior (Group I, n = 20) or posterior (Group II, n = 5) fractures. The remaining 67 patients (72%) had anterior and posterior element involvement on the same side (Group II, n = 38), bilaterally (Group IV, n = 14), or open perineal wounds (Group V, n = 15). The PASG was applied in 47 patients (51%), and controlled hemorrhage in 12 (71%) of the 17 in whom it was used alone to tamponade pelvic bleeding. Peritoneal lavage was performed in 73 patients (79%). Initial aspirate yielded gross blood in 32 patients; 27 (84%) of these required urgent laparotomy. External skeletal fixation was applied in 19 patients; bleeding was controlled in 18 (95%). Pelvic angiography identified active hemorrhage in three patients and selective embolization was successful in two. Sixty-eight (74%) of the high-risk patients survived. Thirteen (54%) of the 24 deaths were attributable to the pelvic trauma, ten were due to recalcitrant bleeding, and three to delayed sepsis.(ABSTRACT TRUNCATED AT 250 WORDS)

[Q]: Abstract: We studied the importance of a history of appendectomy for appendicitis in 279 women with laparoscopically or surgically diagnosed tubal infertility and a control group of 957 fertile women. After controlling for the effects of age, use of an intrauterine device for contraception, a history of pelvic inflammatory disease, and other potential confounding variables, we found that no excess risk of tubal infertility was associated with a simple appendectomy without rupture. However, when the operation was reportedly for a ruptured appendix, the relative risk of tubal infertility was 4.8 (95 percent confidence interval, 1.5 to 14.9) for women who had never been pregnant and 3.2 (95 percent confidence interval, 1.1 to 9.6) for women with one or more previous pregnancies. We conclude that the early diagnosis and treatment of suspected appendicitis in girls and women of reproductive age may reduce the incidence of tubal infertility resulting from the sequelae of a ruptured appendix.

[Q]: Abstract: Body surface potential maps were recorded from 140 chest leads in 25 patients affected by the idiopathic long QT syndrome (LQTS) and in 25 healthy control subjects matched for age and sex. Potential time integrals of the QRST and ST-T intervals were calculated at each lead point and displayed as isointegral (ISOI) maps. The main abnormalities noted on the QRST and ST-T ISOI maps were one area of negative values larger than normal in the right anterior and inferior thorax and a complex multipeak distribution of the integral values. At least one abnormality was present in 19 (76%) of the patients with LQTS and four (16%) of the control subjects (p less than .001). Each ISOI map was also represented as a weighted sum of nine fundamental components (eigenvectors) to detect and quantitate the nondipolar content. The percent contribution of the nondipolar eigenvectors (all eigenvectors beyond the third) was significantly higher in the LQTS group than in the control group (p less than .005). Specifically, an abnormally high nondipolar content on the QRST ISOI maps was observed much more frequently for patients with LQTS than for control subjects (nine or 36% vs one or 4%), and this was also true on the ST-T ISOI maps (14 or 56% vs one or 4%). No correlation was found between the major abnormalities on body surface maps and syncopal episodes. However, the high prevalence (76%) of these alterations among the patients with LQTS and their infrequent occurrence in the control population strongly suggests that they may be useful markers for the diagnosis of atypical cases. The prominent electronegative area on the anterior thorax can be related to delayed repolarization of a portion of the anterior wall of the heart. This finding is in agreement with the hypothesis that lower than normal right cardiac sympathetic activity is the main pathogenetic mechanism of LQTS. Multipeak distribution and high nondipolar content suggest regional electrical disparities in the ventricular recovery process. This may in part account for the high susceptibility of patients with LQTS to malignant arrhythmias.
