Maternally inherited diabetes and deafness (MIDD): unusual occult exocrine pancreatic manifestation in an affected German family
2000
The mitochondrial (mt) 3243 DNA mutation is an underlying cause of maternally inherited diabetes and deafness (MIDD) syndrome and the syndrome of mitochondrial myopathy, encephalopathy, lactic acidosis and stroke-like episodes (MELAS). We report an affected German MIDD pedigree with maternal lineage over three generations. The index patient, her mother, her maternal aunt and her maternal grandmother all suffered from diabetes and premature hearing loss and were positive on testing for the mt 3243 DNA mutation. The 27-year-old index patient had a history of grand mal seizures. As sequela of abdominal ultrasound and confirmed by magnetic resonance cholangio-pancreaticography, she was diagnose…
Assessment of "grading" with Ki-67 and c-kit immunohistochemical expressions may be a helpful tool in management of patients with flat epithelial aty…
2009
It is essential to reach a better understanding of "flat epithelial atypia/columnar cell lesions" (FEA/CCLs) in breast core biopsies. Our aim was to explore their biological nature, in order to predict the likelihood of an upgrade to carcinoma. "Cytological grading" has been specially focused, in view of its possible utility in the choice of management. One hundred thirty of a total of 900 cases core needle (CN)/vacuum-assisted biopsies (VABs), with diagnoses of "hyperplasia" and "atypia" were retrospectively re-evaluated. Pathological findings of further excision biopsies (FEBs) performed in 40/75 patients with follow-up were compared with the previous diagnoses. In all cases, both Ki-67 a…
Urothelial Leukoplakia: New Aspects of Etiology and Therapy
1987
AbstractWe describe 3 women in 1 family who had systemic urothelial leukoplakia with no underlying pathological condition of the urinary tract. Irritative clinical symptoms resolved, and the macroscopic and microscopic appearance improved after 6 months of therapy with sodium pentosan-polysulfate. Electron microscopy showed special cells in the basal layer of the cornified squamous epithelium that also have been found in the trigone of women with so-called squamous metaplasia. Their similarity to Merkel’s cells of the skin supports the theory that ectodermal cells are misplaced during embryogenesis. Genetic factors and sex hormones seem to influence the development of certain variants of sq…
Reconstructive surgery following resection of primary vulvar cancers.
2005
Objective. This study describes the surgical treatment and follow-up of 213 patients with primary vulvar cancer; particular attention is given to reconstructive surgical procedures. Methods. The clinical and pathological parameters of the patients were recorded according to standardized procedures, and the data concerning type of operation, surgical reconstruction and postoperative course of disease (recurrence-free and overall survival) were analyzed. Results. In about one-third of the cases, plastic surgery reconstruction involving skin-flaps was performed. In the present group of patients, plastic surgery procedures led to an elevated degree of operability as well as to more satisfactory…
Evaluation of the antiproliferative, proapoptotic, and antiangiogenic effects of a double-stranded RNA mimic complexed with polycations in an experim…
2015
Objective To assess the antiproliferative, proapoptotic, and antiangiogenic effects of the double-stranded RNA mimic polyinosine-polycytidylic acid (pIC) complexed with polyethylenimine [pIC PEI ] in xenografted human leiomyomas. Design Heterologous leiomyoma mouse model. Setting University-affiliated infertility center. Animal(s) Ovariectomized and hormone-replaced nude mice (n = 16) who received human leiomyoma fragment transplantation. Intervention(s) Leiomyoma fragments placed in the peritoneum of 5-week-old nude female mice and treated with the vehicle (n = 8) or 0.6 mg/kg [pIC PEI ] (n = 8) for 4 weeks. Main Outcome Measure(s) The size of the leiomyoma implants, and cellular prolifera…
Long-term outcome prediction by clinicopathological risk classification algorithms in node-negative breast cancer--comparison between Adjuvant!, St G…
2009
Background: Defining risk categories in breast cancer is of considerable clinical significance. We have developed a novel risk classification algorithm and compared its prognostic utility to the Web-based tool Adjuvant! and to the St Gallen risk classification. Patients and methods: After a median follow-up of 10 years, we retrospectively analyzed 410 consecutive node-negative breast cancer patients who had not received adjuvant systemic therapy. High risk was defined by any of the following criteria: (i) age 2 cm. All patients were also characterized using Adjuvant! and the St Gallen 2007 risk categories. We analyzed disease-free survival (DFS) and overall survival (OS). Results: The Node-…
Cervical carcinoma: standard and pharmacokinetic analysis of time-intensity curves for assessment of tumor angiogenesis and patient survival
1999
Since detailed knowledge regarding the pathophysiological properties—which in turn are responsible for differences in contrast enhancement—remain fairly undetermined, it was the aim of this study (i) to examine the association of standard and pharmacokinetic analysis of time-intensity curves in dynamic MRI with histomorphological markers of tumor angiogenesis (microvessel density [MVD]; vascular endothelial growth factor [VEGF]) and (ii) to determine the ultimate value of a histomorphological and a dynamic MRI approach by correlation of those data with disease outcome in patients with primary cancer of the uterine cervix. Pharmacokinetic parameters (amplitude A, exchange rate constantk 21) …
MicroRNA expression profile in endometriosis: its relation to angiogenesis and fibrinolytic factors
2014
Study question Could an aberrant microRNA (miRNA) expression profile be responsible for the changes in the angiogenic and fibrinolytic states observed in endometriotic lesions? Summary answer This study revealed characteristic miRNA expression profiles associated with endometriosis in endometrial tissue and endometriotic lesions from the same patient and their correlation with the most important angiogenic and fibrinolytic factors. WHAT IS ALREADY KNOWN?: An important role for dysregulated miRNA expression in the pathogenesis of endometriosis is well documented. However, to the best of our knowledge, there are no reports of the relationship between angiogenic and fibrinolytic factors and mi…
Physical activity and breast cancer risk by pathological subtype
2017
Abstract Objective To examine the influence of physical activity on breast cancer risk and evaluate whether adherence to international recommendations is associated with a decreased risk. Methods This is a multicenter matched case-control study where 698 pairs completed a physical activity questionnaire. Recreational physical activity during the last year was quantified in metabolic equivalent hours per week (MET-h/week) and categorized in activities of moderate (3.0–5.9 MET) and vigorous (>6 MET) intensity. The adherence to World Cancer Research Fund and the American Institute for Cancer Research recommendation was also assessed. The association with breast cancer risk, overall and by path…
Successful treatment of a young patient with locally advanced clear cell adenocarcinoma of the uterine cervix undergoing chemoradiation followed by r…
2014
Clear cell adenocarcinoma (CCAC) of the uterine cervix is a rare variant of cervical adenocarcinoma accounting for approximately 4-9% of this disease. Given the rarity of this pathological entity, the optimal treatment management is far from being defined. Earlier evidence suggested that the prognosis of patients bearing cervical CCAC is worse than with other histotypes, thus making the investigation of multimodal treatment strategies clinically worthwhile. Herein, we report the first case of locally advanced, large size cervical CCAC in a young woman who was triaged to concomitant chemoradiotherapy followed by radical surgery and experienced a pathologically assessed optimal response to th…
