It has been proposed that the imaging workup of trauma patients be accelerated by omitting the initial chest radiography (CR)
and directly performing a computed tomography (CT); however, the baseline CR is then lacking. The purpose of this study was
to assess if coronal thick reconstructions generated from chest CT could present an adequate alternative for CR. Sixty trauma
patients underwent bedside CR and multidetector row chest CT in the emergency room. The image quality of thoracic anatomical
structures, the diagnostic accuracy for chest pathology, and the depiction of indwelling devices were assessed on both modalities.
Main pulmonary arteries and perihilar bronchi were equally visualized with both modalities. Central bronchi, retrocardial
lung parenchyma, diaphragm, descending aorta, and vertebral pedicles were better visualized on thick CT reconstructions, whereas
peripheral lung vessels were better depicted on CR (p<0.05). The accuracy to delineate various pathological findings did not differ between both modalities, except for a higher
sensitivity to diagnose bronchial cuffing on CR (p<0.05). The location of indwelling devices was similarly and correctly depicted with both modalities. Coronal thick CT reconstructions
provide a similar image quality and diagnostic accuracy compared with CR. These reconstructions may serve as an equivalent
baseline image in trauma patients in whom emergency radiological evaluation has to be accelerated. 相似文献

OBJECTIVES: To describe the use of health services by primiparous women with urinary incontinence by (a) examining the quality of life of these women and (b) describing the different predictors associated with their use of health services. DESIGN AND SETTING: This correlative study is a secondary analysis of a broader epidemiologic study. PARTICIPANTS: The 382 women identified as having urinary incontinence in the main epidemiologic study in Quebec, Canada. MAIN OUTCOME MEASURES: Consultation rate; quality of life, predictors of quality of life, and use of health services; treatments received; and reasons for not seeking help. RESULTS: Consultation rate was 11.1%. Many sociodemographic, clinical, and urinary incontinence factors were significantly associated with a decreased quality of life. Only frequency of nocturia, severe urinary incontinence, use of sanitary protection, and lower scores on the quality-of-life scale were significantly associated with differences in consultation rates. Physiotherapy was the most popular treatment received (71.4%). Most women with urinary incontinence did not consult because they considered urinary incontinence to be normal (47.3%). CONCLUSIONS: Few women with urinary incontinence used health services for their urinary incontinence problem despite a decreased quality of life. Health professionals need to intervene early and promptly to help women with urinary incontinence deal more adequately with urinary incontinence and to inform women on how and where to seek help. 相似文献

Takayasu arteritis is a large vessel systemic granulomatous vasculitis characterized by stenosis or obliteration of large
and medium sized arteries. It commonly involves elastic arteries such as the aorta and its main branches. Renal artery involvement
is rare and has not been reported in a child. We report a 12-year-old boy with Takayasu arteritis who developed severe hypertension,
proteinuria, microscopic hematuria and renal dysfunction. Conventional angiography demonstrated aneurysms of both renal arteries
and multiple microaneurysms of the superior mesenteric artery. This case report illustrates that the children with Takayasu
arteritis can develop renal involvement resulting in hematuria, proteinuria and even renal failure. 相似文献

OBJECTIVE: Abdominal wall adhesions at laparoscopy may predispose infertile patients to access-related injuries and increase the complexity of the procedure. We have observed concern from referring physicians regarding the safety of surgical laparoscopy in infertile patients who previously underwent surgery because of the risk of abdominal adhesions. To assess the risk of intraabdominal adhesions at laparoscopy, a retrospective cohort study was performed. METHODS: All infertile patients who underwent a reproductive laparoscopic procedure in a 6-year period at our institution were included in this study. A chart review was performed to obtain demographic/surgical data and identify preoperative risk factors for intraabdominal adhesions. Operative videotapes were reviewed to determine the presence and location of adhesions. Standard statistical analyses were performed. RESULTS: During the study period, 254 infertile patients underwent reproductive surgical laparoscopy, and videotapes on 164 (65%) were available for review. A total of 88 patients (54%) were identified with preoperative risk factors for intraabdominal adhesions (group 1), while 76 (46%) had no risk factors (group 2). The relative risk of adhesions was 1.34 (95% CI, range 0.89 to 2.01, P=0.18) when risk factors were identified. There were no differences in the groups regarding patient age, operative time, access technique, conversion to open surgery, or complications. Estimated blood loss was significantly higher in group 2, likely due to the predominance of laparoscopic surgery for ovarian endometriomata and complexity of the cases rather than the presence or absence of intraabdominal adhesion risk factors. CONCLUSIONS: No difference existed in the risk of intraabdominal adhesions in infertile patients with and without identifiable preoperative risk factors. Preoperative risk factors for intraabdominal adhesions should not contraindicate the surgical laparoscopic approach for reproductive procedures. 相似文献

The rare association of DAA with TOF is reported in a young boy who underwent successfully at the age of 3 months an emergency shunt between the anterior (left) hypoplastic aortic arch and the LPA after the vascular ring was divided. Total correction of the cardiovascular malformation was performed at the age of 4 years. The cardiac catheterization, angiographic and operative findings as well as the management of the case are described. Ten other patients with this combination of anomalies were found on review of the literature, eight of whom had only palliative systemic to pulmonary artery shunts. Knowledge of the morphology of the DAA by angiocardiography is helpful in planning the management. Surgical shunts when done early for the treatment of a patient with repeated anoxic spells may reduce the gravity of psychomotor retardation. A staged surgical repair of TOF is recommended for infants having hypoplastic pulmonary arteries. 相似文献

Surface water from Miri Lake and groundwater from around Kadugli (West-Central Sudan) obtained by means of hand-pumps was analysed for (238)U, (226)Ra, (222)Rn, and (232)Th activity concentrations. The surface water showed very low levels of radionuclide concentrations: <1.0-7.5, 8.5-16.5, <1.6, and <0.1-0.39mBqL(-1) for (238)U, (226)Ra, (222)Rn, and (232)Th, respectively. Groundwater revealed a significant amount of natural radioactivity (16.1-1720, 7.7-14.3, 3000-139,000, <0.1-39mBqL(-1)) respectively. The overall annual effective dose was below the WHO reference dose level of 0.1mSvyr(-1) except in one groundwater sample with an associated dose of 0.7mSvyr(-1). 相似文献

Endogenous Bacillus cereus panophthalmitis 总被引:3,自引:0,他引:3
Over the past seven years we have treated three cases of drug abusers in whom endogenous Bacillus cereus endophthalmitis rapidly progressed to panophthalmitis. Ocular features of infection with this organism include severe pain, chemosis, proptosis, corneal infiltration and ring abscess, subretinal exudation, retinal hemorrhages, and perivasculitis. The process becomes fulminant in an explosive manner and may be accompanied by fever and leukocytosis. Ophthalmologists should be cognizant of the apparent susceptibility of drug abusers to Bacillus cereus infections and should consider this organism in any severe, rapidly evolving intraocular infectious process. 相似文献

OBJECTIVE: To investigate the value of measuring total plasma protein and hemoglobin concentrations for the diagnosis of pulmonary edema secondary to scorpion envenomation. DESIGN AND SETTING: Retrospective study over a 4-year period in the medical intensive care unit of a university hospital. PATIENTS: 67 patients older than 3 years admitted in the intensive care unit for scorpion envenomation and stratified into two groups according to the presence of pulmonary edema assessed by a medical committee that took into account clinical, radiological, and blood gas data at admission and after treatment. Total plasma protein and hemoglobin concentrations were analyzed separately. RESULTS: At admission all patients with and without pulmonary edema exhibited polypnea and tachycardia. The mean plasma protein and hemoglobin concentrations were higher in patients with pulmonary edema (74+/-6 and 14.2+/-2.0 g/dl, respectively) than in those without pulmonary edema (64+/-6 and 12.3+/-1.4 g/dl). After 24 h plasma protein and hemoglobin concentrations decreased in the pulmonary edema group (-11 and -1.9 g/dl) despite a negative fluid balance (-500 ml). A plasma protein concentration of 70 g/l or more predicted the presence of pulmonary edema with a sensitivity of 80% a specificity of 96%, a positive predictive value of 97%, and negative predictive value of 77%. CONCLUSIONS: In scorpion-envenomed patients with cardiorespiratory manifestations high plasma protein and hemoglobin concentrations suggest the presence of pulmonary edema. 相似文献

Cardiac Ca2+ current (ICa) was shown to be regulated by cGMP in a number of different species. Recently, we found that the NO-donor SIN-1 (3-morpholino-sydnonimine) exerts a dual regulation of ICa in frog ventricular myocytes via an accumulation of cGMP. To examine whether NO also regulates Ca2+ channels in human heart, we investigated the effects of SIN-1 on ICa in isolated human atrial myocytes. An extracellular application of SIN-1 produced a profound stimulatory effect on basal ICa at concentrations > 1 pM. Indeed, 10 pM SIN-1 induced a approximately 35% increase in ICa. The stimulatory effect of SIN-1 was maximal at 1 nM (approximately 2-fold increase in ICa) and was comparable with the effect of a saturating concentration (1 microM) of isoprenaline, a beta-adrenergic agonist. Increasing the concentration of SIN-1 to 1-100 microM reduced the stimulatory effect in two thirds of the cells. The stimulatory effect of SIN-1 was not mimicked by SIN-1C, the cleavage product of SIN-1 produced after liberation of NO. This suggests that NO mediates the effects of SIN-1 on ICa. Because, in frog heart, the stimulatory effect of SIN-1 on ICa was found to be due to cGMP-induced inhibition of cGMP-inhibited phosphodiesterase (cGI-PDE), we compared the effects of SIN-1 and milrinone, a cGI-PDE selective inhibitor, on ICa in human. Milrinone (10 microM) induced a strong stimulation of ICa (approximately 150%), demonstrating that cGI-PDE controls the amplitude of basal ICa in this tissue. In the presence of milrinone, SIN-1 (0.1-1 nM) had no stimulatory effect on ICa, suggesting that the effects of SIN-1 and MIL were not additive. We conclude that NO may stimulate ICa in human atrial myocytes via inhibition of the cGI-PDE. 相似文献
