Are trunk stability and endurance determinant factors for whole-body dynamic balance in physically active young males? A multidimensional analysis.

OBJECTIVES: Determine if (a) a better trunk stability and endurance are associated with an improved whole-body dynamic balance, and if (b) the assessment tests can be interchanged within each capability. METHODS: Sixty-three physically active young males performed three trunk stability (i.e., the lumbopelvic stability, the unstable sitting and the sudden loading sitting tests), three trunk muscle endurance (i.e., the Biering-Sørensen, the side bridge and the front bridge tests) and four whole-body dynamic balance (i.e., the tandem and the single-leg stance, the Y-Balance, and the single-leg triple hop tests) tests two times. After assessing the reliability of the variables, a Pearson correlation analysis was performed. RESULTS: The correlations between trunk stability and endurance tests with dynamic balance tests were non-significant except for the unstable sitting test with both the tandem (r = 0.502) and the single-leg stance (r = 0.522) tests. Moreover, no relationships were observed between the trunk stability and the trunk muscle endurance tests. Interestingly, no relationships were found between most tests within each capability (i.e., trunk stability, trunk endurance, and dynamic balance) except: (i) the front bridge stability test and the back (r = 0.461) and the side (r = 0.499) bridge stability tests; (ii) the two side bridge endurance tests (r = 0.786); (iii) the tandem and the single-leg stance tests (0.439 ≤ r ≤ 0.463); (iv) the Y-Balance and the single-leg triple hop tests (0.446 ≤ r ≤ 0.477). CONCLUSION: Better trunk function does not seem to be a relevant factor for dynamic balance in young active males. In this population, specific measures are needed as the test interchangeability is questioned.

Plástica costal en las gibas residuales de las escoliosis: técnica quirúrgica y resultados

Se estudiaron en forma retrospectiva 29 pacientes a quienes se les realizó el tratamiento quirúrgico de la giba costal dorsal producida por la rotación vertebral en la escoliosis. Se observó una gran satisfacción por parte de los pacientes con el resultado global obtenido con tratamiento de la deformidad. No se vieron complicaciones respiratorias de importancia relacionadas con la técnica. Se discuten las indicaciones y los criterios de selección de pacientes y se concluye que este procedimiento es muy útil en el manejo de esta deformidad vertebral

Diagnostic utility of color Doppler ultrasound in lower limb deep vein thrombosis in patients with clinical suspicion of pulmonary thromboembolism.

The diagnosis of pulmonary thromboembolism is frequently based on ventilation-perfusion scintigraphy and ascending lower limb venography when pulmonary angiography is not available. The aim of this study is to compare color Doppler ultrasound against ascending venography in the evaluation of the lower limb deep vein system in patients with clinical suspicion of pulmonary embolism, with special attention to calf veins. We prospectively studied 30 patients with clinical suspicion of pulmonary embolism in whom a color Doppler ultrasound and venogram were performed with no more than a 3-h interval between both procedures. The diagnostic criteria was that of loss of venous compressibility. The 'color' ability was used to identify artery from vein. Out of 15 patients in whom a venogram proved positive (50%), 9 had isolated calf vein thrombosis (60%). In 5 patients, the color Doppler ultrasound of the calf was considered inconclusive. Overall sensitivity was 53%, specificity 100%, positive predictive value 100%, and negative predictive value 68%. In the femoropopliteal system, sensitivity was 83% and specificity 100%. Considering all patients, sensitivity in the calf system was 40%. Excluding the 5 patients who were difficult to assess, sensitivity increased to 60%. In conclusion, color Doppler ultrasound is not as sensitive as venography in dealing with patients with clinical suspicion of pulmonary embolism, due to its low sensitivity in the calf system when distal thrombi need to be excluded. However, a reasonable alternative is to begin by performing a compression ultrasonography of the femoropopliteal system. Color Doppler ultrasonography of the calf system represents a rarely sensitive and arduous task and does not seem justifiable in this type of patient.(ABSTRACT TRUNCATED AT 250 WORDS)

Müllerian abnormalities in fertile women and recurrent aborters.

Ninety-six women with recurrent first-trimester spontaneous abortions underwent hysterosalpingography to rule out müllerian abnormalities, both congenital and acquired. Results were compared with those in 96 women who had undergone hysterosalpingography before artificial insemination by donor and subsequently had a full-term, normal delivery. The patients with two recurrent, consecutive abortions had müllerian abnormalities similar to those in women with three consecutive abortions; however, they had different müllerian abnormalities than did the control group. Congenital and acquired malformations seen most often in patients with recurrent abortions were septate, arcuate and bicornuate uteri and incompetent cervical os. Pelvic examination did not discriminate between patients with recurrent abortions and the control group.

Triple evaluation of tubal patency.

A series of 336 infertile patients were evaluated by tubal insufflation, hysterosalpingography, and laparoscopy. The treee procedures revealed patient tubes in 175 patients (52%) and occluded ones in 44 (13%) patients. Thus results with the three methods agreed in 219 patients (65%). False results of tubal insufflation were 18.5% (9.8% false negative and 8.6% false positive). False negative results of hysterosalpingography are 9.5% and false negative results of laparoscopy are 6.8%. Additional pelvic pathology detected by laparoscopy was seen 60 patients (17.8%). Pelvic adhesions (36 patients) and endometriosis (24 patients) were the pathologic processes most commonly missed by hysterosalpingography. Suspected pelvic pathology was corrected by laparocopy in nine cases (2.6%). Double evaluation, both by hysterosalpingography and laparoscopy was needed in 30% of the infertile patients, and therefore both methods should be considered supplementary. Provided that both hysterosalpingography and laparoscopy can be performed, tubal insufflation, since it gives no further information, should be abandoned or discrepant results rejected.
