CT and MR Imaging Evaluation of Hepatic Adenoma
2006
Hepatic adenoma is a rare benign epithelial tumor that is usually encountered in young women who use oral contraceptives. It is clinically significant because of the risk of hemorrhage and of its low-grade malignancy potential. Adenomas usually are mildly hypervascular at contrast-enhanced CT and MR imaging, and heterogeneous due to the presence of hemorrhage, necrosis, calcifications and fat. The objective of our study was to illustrate the CT and MR imaging findings of hepatic adenoma.
Perfusion MRI in normal and abnormal pituitary gland. A preliminary study.
1997
Perfusion MRI (magnetic resonance imaging) of the pituitary gland was performed in 20 healthy volunteers and 63 patients with various lesions involving the pituitary gland. All patients underwent sequential contrast-enhanced MRI using spoiled gradient recalled sequences with high temporal resolution (7 seconds). Four pituitary areas (pituitary stalk, posterior lobe, postero-superior, and antero-inferior adenohypophysis) were tested with a selected region of interest. Maximal contrast percentual variation was calculated. The timing of enhancement in normal patients matched perfectly with normal pituitary vascularization. Abnormal timing in pathological condition was investigated.
Hypermineralocorticoidism and hypertension
1971
Die mit Hypokaliamie, Uberproduktion von Mineralocorticoiden (Aldosteron und/oder Corticosteron und Desoxycorticosteron) und Aktivitatsanderungen des Renin-Angiotensinsystems einhergehenden Hochdrucksformen werden beschrieben. Sie lassen sich nach willkurlich gewahlten biochemischen Kriterien in drei Gruppen einteilen: a) Hypermineralocorticoidismus mit Reninsuppression und Aldosteronismus, b) Hypermineralocorticoidismus mit Reninund Aldosteronsuppression und c) Hypermineralocorticoidismus mit erhohtem Plasmarenin und Aldosteronismus. Jede dieser Gruppen besteht aus mehreren Syndromen, die sich durch ihr adrenocorticales Sekretionsmuster und/oder ihre morphologischen Nebennierenrindenverand…
Chromo- and magnifying endoscopy for colorectal lesions
2005
It is essential to identify patients with premalignant or early malignant changes during colonoscopy. Thus, curative resection can be offered. At present, endoscopy can be performed with new powerful high-resolution or magnifying endoscopes. Comparably to the rapid development in chip technology, the optic features of the newly designed endoscopes offer resolutions which allow new mucosal surface details to be seen. In conjunction with chromoendoscopy, the newly discovered tool video endoscopy is much easier and more impressive than with conventional fibre optics. This review summarizes the value of magnifying endoscopy in the lower gastrointestinal tract and focuses on colorectal lesions.
Congenital undifferentiated sarcoma associated to BCOR-CCNB3 gene fusion
2017
Small round cell sarcomas are aggressive bone and soft tissue tumors that predominantly affect children and young adults. A new group of sarcomas with a recurrent BCOR-CCNB3 gene fusion has been recently identified in previously unclassifiable small round cell sarcomas. BCOR-CCNB3 sarcomas share clinical and pathologic similarities with Ewing sarcoma, but show a stronger male predilection and less aggressiveness, as well as distinct gene expression profiling and pangenomic SNP array analyses. We report the unusual case of a congenital BCOR-CCNB3 retroperitoneal sarcoma in a female born at 34th gestational week, which was diagnosed in necropsy after 21hours of life. Immunohistochemical analy…
Risk Perception and Psychological Distress in Genetic Counselling for Hereditary Breast and/or Ovarian Cancer
2017
International audience; Oncological Genetic Counselling (CGO) allows the identification of a genetic component that increases the risk of developing a cancer. Individuals' psychological reactions are influenced by both the content of the received information and the subjective perception of their own risk of becoming ill or being a carrier of a genetic mutation. This study included 120 participants who underwent genetic counselling for breast and/or ovarian cancer. The aim of the study was to examine the relation between their cancer risk perception and the genetic risk during CGO before receiving genetic test results, considering the influence of some psychological variables, in particular…
Setbacks in the process of assimilation of problematic experiences in two cases of emotion-focused therapy for depression
2016
Research on the assimilation model has suggested that psychological change takes place in a sequence of stages punctuated by setbacks, that is, by transient reversals in the developmental course. This study analyzed such setbacks in one good outcome case and one poor outcome case of Emotion-focused therapy (EFT) for depression.Intensive analyses of five transcribed sessions from each case identified 26 setbacks in the good outcome case and 27 in the poor outcome case. The reason for each setback was classified into one of four categories: balance strategy, exceeding the therapeutic zone of proximal development either induced by the therapist (ZPD-T) or induced by the client (ZPD-C), or spon…
Two sides of the same coin? A new instrument to assess body checking and avoidance behaviors in eating disorders
2017
Body checking (BC) and avoidance behaviors (BA) are the dominant behavioral features of body image disturbances (BID) that characterize most individuals with eating disorders (EDs). Whereas BC can be reliably assessed, a valid assessment tool for BA is lacking, preventing an adequate assessment of BID differences across different EDs (anorexia nervosa, AN; bulimia nervosa, BN; binge eating disorder, BED). A total of 310 women with EDs and 112 nonclinical controls completed measures of BC-, BA- and ED-related symptoms. BA did not differentiate between EDs, whereas BC did: it was highest in AN and BN, and lowest in BED. Multivariate analyses also discriminated AN from BN based on BC. Given th…
Assisting relapse prevention in OCD using a novel mobile app-based intervention: A case report.
2018
Mobile health apps increase the accessibility of cognitive-behavioral–based interventions before, during, or following treatment. GGOC is a mobile app designed to challenge maladaptive beliefs in obsessive-compulsive disorder (OCD). This single-case study assesses the usefulness of GGOC as a relapse prevention tool for OCD. The patient was a 26-year-old woman with severe contamination and washing/cleaning OCD symptoms (Y-BOCS = 33). GGOC was used for relapse prevention following CBT treatment. The patient completed 47 levels dedicated to OCD-relevant maladaptive beliefs. Before and after GGOC, the Y-BOCS, Obsessive-Compulsive Inventory (OCI-R), Obsessive Beliefs Questionnaire (OBQ-20), and…
Outcomes for adults with anorexia nervosa who do not respond early to outpatient treatment
2021
Objective: To better understand those patients with anorexia nervosa who do not show early response to treatment and are likely to have poorer outcome. Method: From an existing data set of 187 patients with anorexia nervosa across 22 eating disorder outpatient services in the United Kingdom, participants who had started treatment and had at least one body mass index (BMI) observation in the first 6 weeks of treatment were eligible for these secondary analyses (N = 65), a latent class analysis of BMI change over the first 6 weeks of treatment. Fifty-six patients showed no early change in BMI. We used logistic regression to examine predictors of good outcome in the 40 participants who had 12-…
