RESUMO

BACKGROUND: Visual vertigo (VV) is a disease characterized by various visual signal-induced discomforts, including dizziness, unsteady balance, activity avoiding, and so forth. Distinguishing it from other kinds of dizziness is important because it needs the combination of visual training and vestibular rehabilitation together. However, there is no appropriate tool to diagnose VV in China, thus we would like to introduce an effective tool to China. OBJECTIVE: The aim of this study was to establish the reliability and validity of the Chinese version of visual vertigo analogue scale (VVAS-CH) and to achieve its crosscultural adaptation in order to promote its further usage in China. METHODS: A total of 1681 patients complaining of vertigo or dizziness were enrolled and they were asked to complete the VVAS-CH. The cross-cultural adaptation, reliability and construct validity of the VVAS-CH were determined. RESULTS: Split-half reliability was 0.939, showing a good reliability. Factor analysis identified only one common factor for the nine items that explained 64.83% of the total variance. Most fit indices reached acceptable levels, proving the good fit of the VVAS-CH model. CONCLUSIONS: The VVAS-CH validated in this study can be used as an effective tool for diagnosing and evaluating VV in patients whose native language is Chinese.

RESUMO

BACKGROUND: Low-grade endometrial stromal sarcoma (LGESS) classically exhibits a proliferative morphology. However, morphological variation of extrauterine tumors presents a diagnostic challenge. CASE SUMMARY: We report the case of a 76-year-old female patient with extensive extrauterine and abdominal neoplastic lesions. Computed tomography showed massive pleural and ascitic fluid, and there was an increase in serum cancer antigen 125. She underwent bilateral adnexectomy and tumor resection. The right ovary had been replaced by a multinodular mass that was 8.5 cm × 4.5 cm × 3.5 cm in size. In addition, there was a 24 cm × 15 cm × 13 cm mesenteric mass, which was also multinodular, with local invasion of the intestinal serosa and underlying muscle. Under the microscope, the tumors in different places exhibited two different patterns, thus presenting great challenges to diagnosis and treatment. Thorough pathological assessment eliminated all differential diagnoses in favor of metastatic LGESS derived from a 20-year-old primary tumor initially misdiagnosed as leiomyosarcoma. CONCLUSION: LGESS morphology varies according to tumor location. Accurate diagnosis is critical for appropriate treatment and improved prognosis and patient care.

RESUMO

Postoperative bleeding is the most frequent serious complications after vacuum-assisted breast biopsy (VABB). The aim of this study was to evaluate the clinical effect of using urinary balloon catheter to prevent postoperative bleeding after ultrasound-guided VABB. From May 2016 to June 2018, 324 patients who underwent ultrasound-guided VABB were randomized into the study group and control group. In the study group, an urinary balloon catheter was inserted into the excision cavity to prevent bleeding and hematoma. In the control group, compression with thorax pressure bandage was used for hemostasis. Postoperative subcutaneous ecchymosis and hematoma were recorded and compared between the two groups. The rates of postoperative ecchymosis and hematoma in the study group were significantly lower than that in the control group (5.6% vs 13.0%, P < .05; 8.0% vs 20.4%, P < .05). Among patients with lesions ≤1.5 cm, the rates of postoperative ecchymosis and hematoma were 2.9% and 4.3% in the study group, 6.5% and 11.7% in the control group, but there was no statistically significant difference between the two groups (P > .05). Among patients with lesions >1.5 cm, the rates of postoperative ecchymosis and hematoma in the study group were significantly lower than that in the control group (7.6% vs 18.8%, P < .05; 10.9% vs 28.2%, P < .05). Hemostasis with balloon urinary catheter is a safe and effective method to prevent postoperative bleeding after VABB.

RESUMO

Mammary ductoscopy (MD) is commonly used to detect intraductal lesions associated with nipple discharge. This study investigated the relationships between ductoscopic image-based indicators and breast cancer risk, and developed a nomogram for evaluating breast cancer risk in intraductal neoplasms with nipple discharge. A total of 879 consecutive inpatients (916 breasts) with nipple discharge who underwent selective duct excision for intraductal neoplasms detected by MD from June 2008 to April 2014 were analyzed retrospectively. A nomogram was developed using a multivariate logistic regression model based on data from a training set (687 cases) and validated in an independent validation set (229 cases). A Youden-derived cut-off value was assigned to the nomogram for the diagnosis of breast cancer. Color of discharge, location, appearance, and surface of neoplasm, and morphology of ductal wall were independent predictors for breast cancer in multivariate logistic regression analysis. A nomogram based on these predictors performed well. The P value of the Hosmer-Lemeshow test for the prediction model was 0.36. Area under the curve values of 0.812 (95 % confidence interval (CI) 0.763-0.860) and 0.738 (95 % CI 0.635-0.841) was obtained in the training and validation sets, respectively. The accuracies of the nomogram for breast cancer diagnosis were 71.2 % in the training set and 75.5 % in the validation set. We developed a nomogram for evaluating breast cancer risk in intraductal neoplasms with nipple discharge based on MD image findings. This model may aid individual risk assessment and guide treatment in clinical practice.

RESUMO

Central urotensin II (UII) may participate in the regulation of cardiovascular functions by stimulating sympathy pathway. However, the central mechanism remained unknown. Recent studies have shown that brain reactive oxygen species (ROS) mediate the sympatho-excitatory effects. In the present study, we tested the hypothesis that ROS mediate central cardiovascular effects of UII. Experiments were conducted in Wistar-Kyoto (WKY) rats and spontaneously hypertensive rats (SHR). Immunocytochemistry, intracerebroventricular (icv) infusion and lucigenin-enhanced chemiluminescence assay were employed to detect UII receptor expression and ROS level, respectively. The following results were obtained: (1) Expressions of UII receptors of rostral ventrolateral medulla (RVLM) and nucleus tractus solitarii (NTS) were increased in SHR rats compared with WKY rats (P < 0.05). (2) UII (icv) significantly increased mean arterial pressure (MAP) (P < 0.05), and the effect of UII was significantly more pronounced in SHR rats than that in WKY rats (P < 0.05); (3) Tempol (a superoxide dismutase mimic) or Urantide (an antagonist of UII receptor) pretreatments eliminated the pressor effect of UII (P < 0.05) in SHR rats; (4) Brain superoxide level was increased in UII-treated SHR rats compared with that in cerebrospinal fluid (CSF)-treated SHR rats (P < 0.05). These results indicate that ROS mediate central cardiovascular effects of UII in SHR rats and provide evidence for a novel relationship between UII and ROS.
