OBJECTIVE: This article describes the MR imaging features of carcinosarcoma of the urinary bladder with clinical presentation and pathologic correlation in three adults. CONCLUSION: Carcinosarcoma of the urinary bladder is a rare and aggressive tumor that has a clinical presentation similar to that of transitional cell carcinoma of the bladder. Dynamic gadolinium-enhanced MR imaging features are discussed. 相似文献

Despite the effectiveness of clomipramine and selective serotonin reuptake inhibitors (SSRIs) in the treatment of obsessive-compulsive disorder (OCD), 40% to 60% of patients who receive an adequate treatment with these agents have significant persisting symptoms. Newer atypical antipsychotic drugs showed efficacy as augmenting agents in patients with OCD resistant to serotonin reuptake inhibitors (SRIs). The objective of this study was to evaluate the efficacy and safety of amisulpiride augmentation in treatment resistant OCD. A total of 20 patients diagnosed with OCD according to DSM-IV criteria and having a history of resistance to treatment with SRIs were included in the study. Amisulpiride 200 mg/day was added to ongoing SRI treatment and titrated up to 600 mg/day in flexible doses. The mean amisulpiride dose was 325 +/- 106 mg/day. The patients were assessed with the Yale-Brown obsessive-compulsive scale (Y-BOCS) at baseline and at week 12 of amisulpiride treatment. Side effects were monitored by the UKU side effect rating scale. The reduction in Y-BOCS scores between the baseline (26.7 +/- 6.3) and the end of the treatment (12.5 +/- 2.8) was statistically significant (p=0.0001). The most commonly observed side effects included weight gain (14 patients, 70%), mild sedation (13 patients, 65%) and asthenia (7 patients, 35%). This study has several limitations and, hence, the results are preliminary and require confirmation in a randomized controlled trial. In conclusion, this study suggests that amisulpiride may be a promising option as an augmentation strategy in treatment resistant OCD. 相似文献

BACKGROUND: The 2001 Bethesda System recommended qualification of atypical glandular cells (AGC) to indicate the site of origin and separated endocervical adenocarcinoma in situ (AIS) from "AGC favor neoplastic" as a specific diagnostic category. To the authors' knowledge, the literature evaluating the reproducibility of Papanicolaou (Pap) smear diagnosis of glandular cell abnormalities with emphasis on the cell of origin is limited. The aim of the current study was to investigate whether a variety of benign to neoplastic glandular lesions can be reliably classified on Pap smear with regard to diagnosis and cell of origin. METHODS: Twenty-three conventional Pap smears (CPS) with glandular cellular changes varying from benign to adenocarcinoma (ACA) were reviewed by six observers. They were asked to categorize each smear according to cell of origin (endocervical vs. endometrial) and diagnosis (benign, AGC, or ACA). Kappa statistics were used to evaluate interobserver agreement and correlation of interobserver agreement with experience. RESULTS: There was no consensus among observers for both the origin of the cells and the diagnosis. Interobserver agreement for site was poor (kappa < 0.4) especially in the AGC category. Unanimous agreement for site was reached for 7 of 23 smears (30%). Two of five endocervical AIS were classified as endometrial and another two were classified as benign by four observers. Interobserver agreement was poor in all diagnostic categories (kappa < 0.4) and showed slight correlation with level of experience. Unanimous agreement for diagnosis was reached for only 2 smears (9%). Three of 11 (27%) smears demonstrating preneoplastic/neoplastic processes were diagnosed as benign by 3 observers. Three (25%) benign CPS were diagnosed as ACA by 2 observers. Accurate prediction of the final histologic diagnosis by observers varied from 30% to 87% and did not correlate closely with experience. CONCLUSIONS: Cytologic diagnosis of glandular lesions by CPS was problematic and suffered from significant interobserver subjectivity. 相似文献

The Annual Meeting of the American Society for Cell Biology (ASCB) is a diverse conference covering all topics in cell biology. While all of the basic biology presented at this meeting may potentially contribute to breast cancer research, there were a significant number of presentations and posters directly pertinent to this field. Here we have summarized the research that is of greatest immediate relevance to breast cancer, with particular emphasis on mammary gland development and tumorigenesis in vivo, three-dimensional in vitro models of mammary morphogenesis, alterations of signal transduction pathways in breast cancer, and global studies in expression profiling and drug screening. 相似文献

Testicular atrophy is a sequela of inguinal hernioplasty. The purpose of this study was to evaluate the effects of Lichtenstein (LHR) and laparoscopic totally extraperitoneal (TEP) hernia repair techniques on testicular function and volume. This study is a randomized prospective clinical trial with the blind assessment of outcome. A total of 26 patients who underwent elective herniorrhaphy for groin hernia were included in the study. Each patient was randomly assigned into one of two groups: either TEP or LHR (n = 13 for each). Six of the patients had bilateral hernia (n = 3 for each group). Luteinizing hormone (LH), follicle stimulating hormone (FSH), testosterone levels, and testicular volume by Doppler ultrasonography were detected just before and 3 months after the operation. LH, FSH levels did not change, when compared preoperative and postoperatively in both groups. Testicular volume and testosterone levels were observed to be significantly decreased after TEP when compared with LHR while no significant preoperative changes were observed between those groups. This affected the testicular volume in normal limits. TEP or LHR could not affect LH, FSH, testosterone values, but TEP could lead a decreasing effect on volume of testis in normal limits. 相似文献

Transient myeloproliferative disorder is a self limiting disorder characterized by leukocytosis with the presence of megakaryoblasts in the peripheral blood and bone marrow, anemia, thrombocytopenia, and organomegaly. It occurs in approximately 10% of newborn infants with Down syndrome. Hepatic fibrosis is seen in the severe form of transient myeloproliferative disorder with Down syndrome that is characterized by diffuse intralobular sinusoidal fibrosis and extramedullary hematopoesis. We describe a patient with hydrops fetalis, Down syndrome, and transient myeloproliferative disorder. We suggest that patients with the severe form of transient myeloproliferative disorder should be examined for hepatic fibrosis. 相似文献

The eyelid–eyebrow region is the center for facial expression. Youth and beauty are associated with smooth, wrinkle-free
skin and proportional facial features. The position of the eyebrows conveys emotion, and consequently, even a minor change
in brow position can alter the expression of an individual's face. Repositioning the eyebrows and reducing the prominence
of the glabellar frown lines can change the expression from one of anger and hostility to one that is more pleasant and natural.
Various methods have been used for rejuvenation of the upper face. The height or length of the forehead is a useful guide
for choosing the appropriate technique. We performed the coronal browlift using the subgaleal dissection plane, with subperiosteal
dissection of 2.5 cm of the periosteal band over the supraorbital rim. We believe that this technique provided us with the
benefits of the two dissection planes, with a more permanent result. 相似文献

Purpose: To investigate the effect of bevacizumab in an experimental rabbit model of corneal neovascularization.
Methods: The right eyes of 24 white New Zealand rabbits were included in a corneal neovascularization model using alkaline burn. They were divided into four groups. Topical bevacizumab was installed three times daily in group 1, 5 mg bevacizumab subconjunctivally every 2 days in group 2, 10 mg bevacizumab subconjunctivally every 2 days in group 3 and 0.2 cc of normal saline in the same way in group 4 (control group). All eyes were treated for 7 days. Then the animals were killed and corneal specimens sent for histopathological analysis. Tear film and aqueous humour samples were obtained to assess vascular endothelial growth factor (VEGF) levels.
Results: Seven days after topical bevacizumab treatment the neovascular index in group 1 was lower than that in the control group ( P = 0.028). In groups 2 and 3 the neovascular index was lower 2 days after subconjunctival bevacizumab treatment than that in control group ( P = 0.009 and P = 0.009, respectively). In the control group the VEGF level in aqueous humour increased by 66% from day 7 to 14. In groups 1–3 it decreased by 49.80%, 70.20% and 76.44%, respectively ( P = 0.043). The VEGF level in tear film of the control group increased by 35.23% from day 7 to 14, which was not significant ( P = 0.893), while in groups 1–3 it decreased by 57.26%, 34.59% and 67.97%, respectively, which was only significant in groups 1 and 3 ( P = 0.043).
Conclusions: Subconjunctival 5 mg/mL bevacizumab is effective in reducing corneal neovascularization in animal models and in reducing VEGF levels. Further research is needed to assess the potential side effects and minimal effective dose. 相似文献
