Significance of ultrasound for the diagnosis of hypertrophic pyloric stenosis

1986

The sonographic features of hypertrophic pyloric stenosis (HPS) were evaluated in a 5-year prospective study (1981–1985) at the University Clinic of Pediatric Surgery in Mainz. In 37 cases real-time ultrasound was performed preoperatively to measure muscle thickness, diameter, and length of the pylorus; the recorded values were compared with those of a control group. Muscular wall thickness proved to be the most reliable parameter, while pyloric canal length was the most difficult measurement to obtain. Diameter alone was not adequate to establish the sonographic diagnosis, which depends on the individually and functionally different luminal width and submucosal thickness. Significant sonog…

99mTc–MAG3–Nierenfunktionsszintigraphie ohne und mit Captopril zur Diagnostik der renovaskulären Hypertonie

1993

In this study, the diagnostic value of renal function scintigraphy performed both without and with ACE inhibition has been evaluated using the new radiopharmaceutical 99mTc-MAG3. In cases of decompensated renal artery stenoses, the typical scan finding with this tubular excreted agent was shown to be a distinct parenchymal nuclide retention in combination with a delayed appearance of the radiotracer in the pelvic system. Using this criterion in 43 patients with suspected renovascular hypertension, sensitivity and specificity were 89 and 88%, respectively. Bilateral positive findings were non-specific; excluding them from the study, specificity increased to 100%. In renal insufficiency, capt…

Kontrastmittelverstärkte 3D-MRA der Pulmonalarterien mit integrierter paralleler Akquisitionstechnik (iPAT) bei Patienten mit CTEPH - sagittale oder …

2004

PURPOSE Comparison of two different types of contrast-enhanced 3D-MR angiography (CE-MRA) with integrated parallel acquisition technique (iPAT) in patients with chronic-thromboembolic pulmonary hypertension (CTEPH) and evaluation whether sagittal acquisition with higher resolution and minimized acquisition time is superior to common coronal orientation. MATERIALS AND METHODS CE-MRA was performed on 15 patients with CTEPH preoperatively and on 10 patients also postoperatively, while 5 other patients received only a postoperative MRA. All 30 MR studies with one coronal and two sagittal acquisitions were blindly evaluated and compared. The resolution of coronal and sagittal MRA was 1.3 x 0.6 x…

THE METABOLIC SYNDROME IN HYPERTENSION

2019

The metabolic syndrome (MS) is currently considered to be a cluster of metabolic and cardiovascular risk factors including blood pressure elevation. A higher risk to develop hypertension in MS subjects with high-normal blood pressure has been observed and, when hypertension is established, seems to be what confers a higher cardiovascular risk on top of the risk induced by blood pressure elevation. Therefore, assessment of MS components can result in clinical utility strategy to manage hypertension based on individual risk. The main mechanisms for blood pressure elevation include overactivity of the sympathetic and the reninangiotensin system, abnormal renal sodium handling, and endothelial …

Der hyperplastische Polyp des Magens - eine Präkanzerose?

2002

In general, hyperplastic polyps of the stomach are regarded as benign lesions. Still there is the chance to find carcinomas within them as documented in this case report. This finding can be interpreted as an incidental appearance. At the moment there are no standardized guidelines regarding diagnostics and therapy of gastric hyperplastic polyps. Referring to a short review of the literature endoscopic snare polypectomy seems to be a reasonable therapeutic option of hyperplastic polyps with a size of 0.5-1 cm. Although it is possible to determine the histology by forceps biopsy, it is possible to be misled by missing areas of focal carcinomas. Complications after polypectomy are rare and of…

The early response of the postmenopausal endometrium to tamoxifen: expression of estrogen receptors, progesterone receptors, and Ki-67 antigen

2003

OBJECTIVE To enlighten the early response of endometrium to tamoxifen by assessing the expression of estrogen receptors, progesterone receptors, Ki-67, and the histological response in endometria from normal postmenopausal women treated for 21 days with tamoxifen. DESIGN A total of 40 women, scheduled to undergo vaginal hysterectomy because of uterine prolapse, were randomly assigned to the tamoxifen group (20 mg/day; 20 women) or the control group (20 women). Samples were obtained from the upper and the lower thirds of the uterine cavity. Standard immunohistochemical staining of estrogen and progesterone receptors and of Ki-67 was performed on frozen sections. Staining was assessed using s…

The Clinical Relevance of LDL Size and Subclasses Modulation in Patients with Type-2 Diabetes

2007

increasing evidence suggest that the "quality" rather than only the "quantity" of low density lipoproteins (LDL) exerts a great influence on the cardiovascular risk. Hypertriglyceridemia, low HDL-cholesterol and increased levels of small dense LDL characterise diabetic dyslipidemia. in subjects with type-2 diabetes LDL size seems also to represent a good marker of clinical apparent and non-apparent atherosclerosis. Recently, the Coordinating Committee of the National Cholesterol Education Program stated that high-risk patients may benefit of stronger therapeutical approaches, a category of subjects that include those with type-2 diabetes. Screening for the presence of small, dense LDL may p…

Relationships Between Biochemical Markers of Hyperandrogenism and Metabolic Parameters in Women with Polycystic Ovary Syndrome: A Systematic Review a…

2019

AbstractWhile several studies have documented an increased risk of metabolic disorders in patients with polycystic ovary syndrome (PCOS), associations between androgenic and metabolic parameters in these patients are unclear. We aimed to investigate the relationships between biochemical markers of hyperandrogenism (HA) and metabolic parameters in women with PCOS. In this systematic review and meta-analysis, a literature search was performed in the PubMed, Scopus, Google Scholar, ScienceDirect, and Web of Science from 2000 to 2018 for assessing androgenic and metabolic parameters in PCOS patients. To assess the relationships between androgenic and metabolic parameters, meta-regression analys…
