Chinese Journal of Ultrasonography 2003;0(07):-
Objective To evaluate the usefulness of color Doppler ultrasonography in differential diagnosis of cervical lymphadenopathy by depicting the intranodal vascular pattern. Methods One hundred and twenty lymph node lesions in 113 patients who underwent color Doppler flow imaging were grouped as reactive lymphadenitis ( n =25), tuberculosis ( n =14), lymphoma ( n =41), and metastasis ( n =40). The vascular patterns of hilar type, central type, peripheral type and mixed type were assessed. Results Most reactive lymph nodes( 92.0%) and lymphomatous nodes( 75.6%) showed hilar vessels,lymphomatous nodes also frequently demonstrated peripheral vessels( 75.6%).Central vessels or peripheral vessels were frequent in metastatic nodes( 60.0% and 57.5%, respectively).The intranodal vascular distribution in tuberculous nodes was simulated malignant disease. Avascularity was observed in 2 of 25 reactive lymph nodes and 1 of 14 tuberculous nodes. Conclusions Central vessels or peripheral vessels were mainly found in malignant lymphadenopathy,and the presence of hilar vessels is suggestive of benign lymphadenopathy. However, there is overlap of appearance between benign and malignant disease.

ObjectiveTo investigate the value of ultrasonography in the diagnosis of the papillary thyroid microcarcinoma (PTMC) in patients with Hashimoto’s thyroiditis (HT).MethodsThis retrospective study used data from Ruijin Hospital of Shanghai Jiaotong University of Medicine during November 2012 to December 2013. A total of 111 small thyroid nodules (75 PTMC/36 benign nodules) with 107 HT cases which were pathologically conifrmed were included in this study. The sonographic characteristics of nodules were investigated, including nodule aspect ratio, shape, border, margin, acoustic halo, internal structure, echo level, microcalciifcations, rear acoustic attenuation, vascular pattern and extent of the blood supply and the types of thyroid tissue echogenicity. Chi-square test and Fisher′s exact probability method was used to compare the differences of the sonographic characteristics between the benign nodules and malignant nodules. With surgical pathology as the gold standard, computing the value of ultrasonography in the diagnosis of PTMC with HT, including the sensitivity, speciifcity, diagnostic accuracy, positive predictive value and negative predictive value.ResultsA total of 111 thyroid tiny nodules (75 PTMC/36 benign nodules) with 107 HT cases which were pathologically conifrmed were included in this study. The results showed 111 small thyroid nodules as solid hypoechoic. Four indexes between PTMC and benign nodules had statistical signiifcance, such as margin, microcalciifcations, vascular pattern and extent of the blood supply. The other six indexes between PTMC and benign nodules had no statistical significance, such as aspect ratio, shape, border, acoustic halo, rear acoustic attenuation and the types of thyroid tissue echogenicity. Ultrasound diagnostic accuracy of small tyroid nodules in patients with HT was 74.77% (83/111). The sensitivity, specificity, diagnostic accuracy, positive predictive value and negative predictive value of the ultrasound diagnosis of PTMC were 93.33% (70/75), 36.11% (13/36), 74.77% (83/111), 75.27% (70/93), and 72.22% (13/18), respectively.ConclusionsCompared with general population, some classic ultrasound features became less effective in patients with HT. However, ultrasonography has some differential diagnostic value in these cases.

Objective To explore the pathological basic of some common characteristic of papillary microcarcinoma of thyroid in ultrasound. Methods Totally 117 thyroid papillary microcarcinomas that were completed all thyroid ultrasound examinations before the surgical excisions were collected. Shape, border, internal echogenicity, halo, posterior echogenicity and calciifcation were observed in ultrasound. While the degree of inifltration of the tumor, the tumor’s internal structure as well as calciifcation was observed in pathology. Results IIrregular shape (87.18%, 102/117), unclear border (80.34%, 94/117), hypoechoic (90.60%, 106/117) and microcalciifcations (65.81%, 77/117) were recognized by ultrasound while the main pathological features were invasive growth (93.16%, 109/117), cell components internally (46.15%, 54/117) and calciifcation (56.41%, 66/117). Of the 109 neoplasms which were invasive growth in pathology, 102 (93.58%) nodules presented irregular shape in ultrasound while 91 (77.78%) presented unclear border. All of the 8 neoplasms which were not invasive growth in pathology showed regular shape in ultrasound. Thirteen nodules showed halos in ultrasound, and 8 of them showed visible ifbrous capsule surrounding the mass. Whatever the tumor’s internal structure was, most nodules presented hypoechoic. And the hyperechoic nodules were all found cell components internally. Of the 66 neoplasms which were found calciifcation by microscope, 35 (53.03%) nodules showed calciifcation in ultrasound and 31 (46.97%) did not. And of the 51 neoplasms in which calciifcation were not found by microscope, 42 (82.35%) nodules showed calciifcation in ultrasound and 9 (17.65%%) did not. Conclusions There is no doubt that all the performances of papillary microcarcinoma in ultrasound have bases in pathology. It is helpful to the judgment of a thyroid nodule if we could understand the correlation of performances in ultrasound and pathology.

Objective To study the effects of early application of integrated traditional Chinese medicine (TCM)and western medicine and massage on the incidence and severity of pneumonia and prognosis in the therapeutic course of infants with cytomegalovirus(CMV)infection infantile cholestatic hepatopathy(ICH)accompanied by gastric volvulus(GV). Methods A prospective randomized controlled trial was conducted. 120 infants 1-6 months old with CMV infection ICH and complicated with GV inpatients were divided into treatment group and control group (each,60 cases). The TCM Lidanheji(consisting of artemisiae capillaris 30 g,weeping forsythia 30 g,Chinese goldthread 5 g,prepared rhubarb 5 g,unpeeled root of herbaceous peony 30 g,cassia 5 g,fruit of citron or trifoliate orange 10 g,large-headed atractylodes 10 g,fruit of Chinese magnoliavine 10 g,pangolin scale 3 g and licorice root 5 g)for oral administration or enema and ganciclovir intravenous injection were given to both groups. In the control group,based on the above treatment,postural and diet therapy,prokinetics(domperidone)were given in cases with GV. The massage treatment was only applied for treatment of GV in treatment group. The pneumonia in both groups was treated in accord to the conventional diagnosis and treatment for infantile pneumonia,bronchiolitis,severe pneumonia and the guide and management of infantile community acquired pneumonia. The total number of cases with pneumonia and its severity occurring before and after treatment in the course of the disease,the clinical therapeutic effects of ICH, GV and infantile pneumonia,the clinical physical signs,biochemical indexes and the time of hospitalization were observed and compared between the two groups. Results Compared with control group,after treatment the curative rate and total effective rate of ICH,GV,infant pneumonia in treatment group were significantly higher〔the curative rate of ICH:83.05%(49/59)vs. 71.93%(41/57),total effective rate:96.61%(57/59)vs. 91.23%(52/57);the curative rate of GV:72.88%(43/59)vs. 51.79%(29/56),total effective rate:96.61%(57/59)vs. 78.57%(44/56);the curative rate of infant pneumonia:81.08%(30/37)vs. 67.44%(29/43),total effective rate:100%(37/37)vs. 100%(43/43),P<0.05 or P<0.01〕. In the treatment group,the total number of cases with pneumonia occurring in the therapeutic course and the incidence of severe pneumonia were significantly less than those in the control group〔the occurrence of pneumonia:12 cases vs. 21 cases,the incidence of severe pneumonia:16.67%(2/12) vs. 42.86%(9/21),P<0.05 or P<0.01〕. The enlargement of liver and spleen,the level of total bilirubin(TBil), direct bilirubin(DBil),total bile acids(TBA)and alanine aminotransferase(ALT)in two groups after treatment were significantly lower than those before treatment,the changes being more marked in treatment group(P<0.05 or P<0.01). The time of stay in hospital in treatment group was remarkably shortened(days:21.32±3.26 vs. 27.38±6.09, P<0.05). Conclusion Early interference with combined TCM and western medicine and massage for treatment of infants with CMV infection ICH accompanied by GV can significantly decrease the incidence of pneumonia and its severity occurring in the disease course,therefore this therapeutic method is beneficial to the treatment and prognosis of infants with CMV infection ICH.
