Thyroid volume measured by ultrasonography and CT 总被引:3,自引:0,他引:3
Nygaard B Nygaard T Court-Payen M Jensen LI Søe-Jensen P Gerhard Nielsen K Fugl M Hegedüs L 《Acta radiologica (Stockholm, Sweden : 1987)》2002,43(3):269-274
Purpose:
To evaluate measurements of thyroid volume by two different US methods and CT in a blinded design. Material and Methods:
Four observers evaluated 27 patients. Observer 1 used US and calculated thyroid volume based on recordings of cross-sections through the gland. Observer 2 used US and calculated the volume of each lobe as a rotation ellipsoid. Observers A and B used CT images and calculated thyroid volume based on recordings of cross-sections through the gland. All measurements were made twice. Results:
The median thyroid volume was 81 ml (range 7-470 ml) evaluated by CT. All three methods had fair reproducibility. When correlating the two different methods using US, an r of 0.837 was found. When correlating data from patients without intrathoracic goitre evaluated by US (Observer 1) and CT, r = 0.945. The method based on a rotation ellipsoid systematically produced smaller thyroid volumes than those of the cross-sectional method. Evaluation by US systematically produced smaller thyroid volumes than CT. Conclusion:
Calculation of thyroid volume based on US recordings of cross-sectional areas is a reproducible method in patients without substernal goitre extension. The US method calculating thyroid volume as a rotation ellipsoid is less reproducible, especially in large goitres. Measurement of thyroid volume using CT should be preferred in goitres with substernal extension. 相似文献

Clinical studies with bisphosphonates in children with osteogenesis imperfecta (OI) show an increase in BMD and a decrease in fracture rate. Bone strength in children with OI is not only influenced by changes in BMD but also by changes in collagen I structure of the organic bone matrix. Therefore, we studied the interaction between these two factors in a cross-sectional, single center study including 54 children. We assumed that vertebral deformities in OI represent an unbalance between load and bone strength. Body weight was considered to be a well quantifiable load on vertebral bodies. BMD served as a marker, representing the amount of bone tissue available for vertebral load bearing, and the Sillence classification, either type I or III/IV, as a marker representing the quality of the organic bone matrix. Independent associations were observed between the prevalence of vertebral deformities and (1) Sillence type (OR: 5.7, 95%Cl:1.2–26.8), (2) BMD (OR: 0.003, 95%Cl: 0–0.25) and (3) body weight (OR: 1.15, 95%Cl: 1.05–1.25). Regarding the anthropometrical differences among the different types of OI, the BMD/body weight ratio was introduced to evaluate the BMD in relation to body size. Prevalent vertebral deformities were associated with low BMD/body weight ratios (OR: 0.04, 95%Cl: 0.008–0.2) in OI type I, but no association was found in type III/IV. It was concluded that BMD and Sillence type have independent relationships with vertebral deformities. The BMD/body weight ratio correlates with vertebral deformities in children with OI type I. Its meaning in types III/IV needs further research with larger samples because of the relatively high prevalence of vertebral deformities in this group. 相似文献

BackgroundTools for diagnosing sexual dysfunction and for tracking outcomes of interest include clinician interviews, physical exam, and patient self-report. Limited work has described relationships among these three sources of information regarding female sexual dysfunction and vulvovaginal health.AimWe describe correlations among data collected from clinician interviews, clinical gynecological examination, and patient self-report.MethodsData are from a single-site, single-arm, prospective trial in 100 postmenopausal patients with a history of breast or endometrial cancer who sought treatment for vulvovaginal symptoms. The trial collected a standardized clinical gynecologic exam, clinician-reported outcome (ClinRO) measures of vulvovaginal dryness and pain, and patient-reported outcome (PRO) measures of sexual function, including PROMIS Sexual Function and Satisfaction (SexFS) lubrication, vaginal discomfort, labial discomfort, and clitoral discomfort and Female Sexual Function Index (FSFI) lubrication and pain. We examined polyserial correlations between measures with bootstrapped 95% confidence intervals from the baseline and 12–14-week timepoints.ResultsAll of the relationships between the ClinRO variables and the PRO variables were in the expected direction (ie, positive), but the strength of the relationships varied substantially. At 12–14 weeks, there were medium-to-large correlations between ClinRO vaginal dryness and SexFS Lubrication (0.64), ClinRO vulvar dryness and SexFS Lubrication (0.46), ClinRO vulvar discomfort and SexFS Labial Discomfort (0.70), and ClinRO vulvar discomfort and SexFS Clitoral Discomfort (0.43). With one exception, the correlations between the exam variables and the corresponding PRO scores were small (range 0.01–0.27).Strengths & LimitationsOur study included a comprehensive, standardized gynecologic exam designed specifically to evaluate sexual dysfunction as well as established PRO measures with significant evidence for validity. A limitation of our findings is that the sample size was relatively small, and our sample was restricted to women who received cancer treatments known to have dramatic effects on vulvovaginal tissue quality.ConclusionPatient- and clinician-reported vulvovaginal dryness and discomfort were moderately correlated with each other but not with clinical gynecologic exam findings. Understanding the relationships among these different types of data highlights the distinct contributions of each to understand vulvovaginal tissue quality and patient sexual function after cancer.

AimTo evaluate and compare parental satisfaction after Plastibell and conventional dissection circumcision.Methods198 children were randomly and equally allocated to two groups (PD: Plastibell and CDS: dissection) for circumcision. Follow-up was done at 7th, 15th and 90th day after surgery. Written questionnaires were given to parents at the time of discharge to complete and return at the 15th and 90th day follow-up visits.ResultsBoth groups were balanced with respect to various demographic factors, indications for surgery and Kayaba's classification of the prepuce. Surgical duration was significantly shorter for the PD as compared to the CDS group (5.91 ± 1.74 min vs. 23.52 ± 5.94 min; p < 0.0001 H.S.). Swelling, dysuria and infection were the prominent problems reported in both groups in the first 7 days. The Plastibell separated earlier in younger children (p < 0.0001). Postoperatively, children in the PD group required 2.79 fold more analgesic than those in the CDS group. 97.9% of parents in the PD group and 80.2% of parents in the CDS group claimed satisfactory aesthetic results. The PD group parents were statistically significantly more concerned about swelling.ConclusionsPlastibell use has comparable outcomes to the conventional dissection technique for paediatric circumcision and has an obvious advantage of shorter surgical duration. However, it is less comfortable in the postoperative period due to swelling, and requires greater use of analgesics. 相似文献

This prospective phase 1/2 trial investigated the safety and reproducibility of allogeneic islet transplantation (Tx) in type I diabetic (T1DM) patients and tested a strategy to achieve insulin-independence with lower islet mass. Ten C-peptide negative T1DM subjects with hypoglycemic unawareness received 1–3 intraportal allogeneic islet Tx and were followed for 15 months. Four subjects (Group 1) received the Edmonton immunosuppression regimen (daclizumab, sirolimus, tacrolimus). Six subjects (Group 2) received the University of Illinois protocol (etanercept, exenatide and the Edmonton regimen). All subjects became insulin- independent. Group 1 received a mean total number of islets (EIN) of 1460 080 ± 418 330 in 2 (n = 2) or 3 (n = 2) Tx, whereas Group 2 became insulin- independent after 1 Tx (537 495 ± 190 968 EIN, p = 0.028). All Group 1 subjects remained insulin free through the follow-up. Two Group 2 subjects resumed insulin: one after immunosuppression reduction during an infectious complication, the other with exenatide intolerance. HbA1c reached normal range in both groups (6.5 ± 0.6 at baseline to 5.6 ± 0.5 after 2–3 Tx in Group 1 vs. 7.8 ± 1.1 to 5.8 ± 0.3 after 1 Tx in Group 2). HYPO scores markedly decreased in both groups. Combined treatment of etanercept and exenatide improves islet graft function and facilitates achievement of insulin-independence with less islets . 相似文献
