BACKGROUND/AIMS: The natural history of chronic hepatitis C (HCV) is not completely understood. This study was aimed to evaluate the long-term outcome of the disease over a prolonged period of time and to identify factors associated with progression. METHODS: One hundred and sixteen patients with non-cirrhotic chronic non-A, non-B hepatitis consecutively diagnosed at a tertiary hospital between 1971 and 1977 were followed until December 1998 or until death. Patients with significant alcohol intake were excluded from the study. Variables obtained at the time of diagnosis, including epidemiological, clinical, laboratory, and histological data were recorded to determine risk factors associated with the development of liver cirrhosis and hepatic decompensation. RESULTS: Based on complete follow-up data, the development of liver cirrhosis and hepatic decompensation was evaluated in 94 and 114 of the 116 patients, respectively. Thirty-seven (39.3%) of 94 patients developed liver cirrhosis; an aspartate aminotransferase (AST) value higher than 70 IU/L was associated with development of cirrhosis (odds ratio (OR) 4.22, 95% CI 1.3-13.8). Hepatic decompensation occurred in 12 (10.5%) of 114 patients, its cumulative probability being 2.8% at 10 years, 5.2% at 15 years and 19.8% at 20 years. The only factor independently associated to the development of hepatic decompensation was the presence of fibrosis (stage 2 or 3) in the initial liver biopsy (OR 4.1, IC 95% 1.22-13.9). Liver-related death occurred only in seven (6%) of 114 patients. In comparison with the 116 patients diagnosed in the 1970's, patients with chronic hepatitis C diagnosed in 1999 were younger, more often asymptomatic, had lower AST and alanine aminotransferase (ALT) values and had significantly lower grade and stage histological scores. CONCLUSIONS: In summary, chronic hepatitis C had a high rate of progression to liver cirrhosis over a prolonged follow-up. However, this might be related to the fact that two decades ago the diagnosis was made at a significantly more advanced stage of the disease. Patients at high risk of progression can be identified by biochemical and histological variables at the time of diagnosis. 相似文献

AIMS: Our objective was to study the anatomic relations of the human left atrial oblique vein (Marshall vein), particularly of its ostium opening into the coronary sinus, in order to guide ablation procedures related to that vein. METHODS AND RESULTS: The study was carried out in 23 heart-specimens (mean weight 446 +/- 204 g) of individuals whose mean ages were 43 +/- 21 years, 20 males. The coronary sinus was opened longitudinally, exposing the ostium of the tributary veins; the Vieussens valve was looked for, as well as its relationship to the left atrial oblique vein. The diameters of the left atrial oblique vein and the coronary sinus ostia were measured and the distance between them was determined. The left atrial oblique vein could be identified in 20 (87%) of the hearts, while the Vieussens valve was present in 17 (74%) of the specimens (in 16 of which the left atrial oblique vein was identified). In such condition, the vein was adjacent to the Vieussens valve and proximally positioned relative to the coronary sinus ostium in most of them (14/16 cases). The mean diameters of the left atrial oblique vein and of the coronary sinus ostia were, respectively, 1.23 +/- 0.38 and 8.22 +/- 1.88 mm. The mean distance between both ostia was 30.9 +/- 10.2 mm. CONCLUSION: When present, the left atrial oblique vein can be easily recognized, adjacent to the Vieussens valve. The mean distance between the coronary sinus opening and left atrial oblique vein ostium was around 30 mm, independently of the heart weight and the presence of cardiomegaly. 相似文献

Background HIV testing is cost-effective in unselected general medical populations, yet testing rates among those at risk remain low,
even among those with regular primary care. HIV rapid testing is effective in many healthcare settings, but scant research
has been done within primary care settings or within the US Department of Veteran’s Affairs Healthcare System.
Objectives We evaluated three methods proven effective in other diseases/settings: nurse standing orders for testing, streamlined counseling,
and HIV rapid testing.
Design Randomized, controlled trial with three intervention models: model A (traditional counseling/testing); model B (nurse-initiated
screening, traditional counseling/testing); model C (nurse-initiated screening, streamlined counseling/rapid testing).
Participants Two hundred fifty-one patients with primary/urgent care appointments in two VA clinics in the same city (one large urban hospital,
one freestanding outpatient clinic in a high HIV prevalence area).
Measurements Rates of HIV testing and receipt of results; sexual risk reduction; HIV knowledge improvement.
Results Testing rates were 40.2% (model A), 84.5% (model B), and 89.3% (model C; p = <.01). Test result receipt rates were 14.6% (model
A), 31.0% (model B), 79.8% (model C; all p = <.01). Sexual risk reduction and knowledge improvement did not differ significantly between counseling methods.
Conclusions Streamlined counseling with rapid testing significantly increased testing and receipt rates over current practice without
changes in risk behavior or posttest knowledge. Increased testing and receipt of results could lead to earlier disease identification,
increased treatment, and reduced morbidity/mortality. Policymakers should consider streamlined counseling/rapid testing when
implementing routine HIV testing into primary/urgent care. 相似文献

We report a rare case in which mechanical extrinsic erosion of the descending thoracic aorta resulted in perforation and periaortic hematoma formation in a 16-year-old girl. Five months before admission to our clinic, the patient had undergone surgical spondylosyndesis with inner vertebral fixation, for the correction of scoliosis. Subsequently, a screw on the fixator became loose, eroding and eventually perforating the wall of the descending aorta. The resultant lesion was at first misdiagnosed as a paravertebral abscess; extrinsic perforation of the descending aorta was suspected prior to operation, but was confirmed only upon surgical exploration. After evacuation of the hematoma, the 1.5-cm aortic perforation was closed directly with continuous sutures. Seven months later, the patient continues to do well. 相似文献

Gangliogliomas are well-differentiated, slow-growing tumors. The majority are grade I of WHO. It appears predominantly in children and young adults. Most are located at the temporal lobe, and as symptomatology more frequent epileptic seizures of difficult pharmacological control. In general, they have a good prognosis after surgical resection. The anaplasic variant, considered to be grade III of the WHO, presents greater clinical and radiological aggressiveness. Leptomeningeal dissemination is exceptional in these types of tumors, but when diagnosed it presents a rapidly progressive and fatal course for the patient. 相似文献

Hip fracture rates in Norway rank among the highest in the world, more than double that of Spanish women. Previous studies were unable to demonstrate significant differences between the two populations with respect to bone mass or calcium metabolism. In order to test whether the difference in fracture propensity between both populations could be explained by differences in bone material quality we assessed bone material strength using microindentation in 42 Norwegian and 46 Spanish women with normal BMD values, without clinical or morphometric vertebral fractures, no clinical or laboratory signs of secondary osteoporosis, and without use of drugs with known influence on bone metabolism. Bone material properties were assessed by microindentation of the thick cortex of the mid tibia following local anesthesia of the area using the Osteoprobe device (Active Life Scientific, Santa Barbara, CA, USA). Indentation distance was standardized against a calibration phantom of methylmethacrylate and results, as percentage of this reference value, expressed as bone material strength index units (BMSi). We found that the bone material properties reflected in the BMSi value of Norwegian women was significantly inferior when compared to Spanish women (77 ± 7.1 versus 80.7 ± 7.8, p < 0.001). Total hip BMD was significantly higher in Norwegian women (1.218 g/cm2 versus 0.938 g/cm2, p < 0.001) but regression analysis revealed that indentation values did not vary with BMD r2 = 0.03 or age r2 = 0.04. In conclusion Norwegian women show impaired bone material properties, higher bone mass, and were taller than Spanish women. The increased height will increase the impact on bone after falls, and impaired bone material properties may further enhance the risk fracture after such falls. These ethnic differences in bone material properties may partly explain the higher propensity for fracture in Norwegian women. © 2015 American Society for Bone and Mineral Research. 相似文献

Objectives To identify factors associated with disease-specific survival (DSS) in intestinal and nonintestinal sinonasal adenocarcinoma.
Design Retrospective review.
Setting Surveillance Epidemiology and End Results database.
Participants Adult patients with sinonasal adenocarcinoma.
Main Outcome Measures DSS.
Results We identified 325 patients; of these, 300 had the nonintestinal type and 25 had intestinal type histologies. The 5-year DSS rates for patients who had no treatment, radiation (RT), surgery, and surgery and postoperative RT were 42.5, 46.1, 85.6, and 72.6%, respectively (log-rank test; p < 0.001). Black race, age ≥ 75 years, paranasal sinus involvement, and high grade were independently associated with decreased DSS. Compared with RT, surgery (hazard ratio [HR]: 0.34; 95% confidence interval [CI]: 0.15–0.77), and adjuvant RT (HR: 0.47; 95% CI, 0.26–0.86) were associated with improved DSS.
Conclusions There is no difference in prognosis between intestinal and nonintestinal subtypes of sinonasal adenocarcinoma. Treatment with surgery alone or adjuvant RT is associated with a more favorable prognosis. 相似文献
