Assoziation einer arteriellen Verschlußkrankheit mit Ciclosporin-Therapie nach Nierentransplantation

2008

Renal transplantation followed by immunosuppression with cyclosporine (whole-blood levels 200-300 micrograms/l) and methylprednisolone (4 mg daily) was performed in a 54-year-old man with chronic glomerulonephritis. Three years later rapidly progressive arterial obstructive disease (peripheral type) developed. Parenteral treatment with prostaglandins, calcium antagonists and nitrates, as well as a lumbar sympathectomy, was unsuccessful so that, in rapid succession, several amputations on upper and lower limbs became necessary. The disease progression was arrested only when azathioprine replaced cyclosporine. Raynaud's phenomenon, present at the time, also disappeared and analgesics were no …

Radiosurgical Treatment of low flow Carotid-Cavernous Fistulae

1991

The good results obtained by stereotactic radiosurgery in arteriovenous malformations has led the authors to expect similar results in low flow carotid-cavernous fistulae. In this paper, 20 cases who underwent radiosurgery with a conventional gamma source are presented. The total dose delivered was 36 to 40 Gy. 90% of the patients were cured after radiosurgery after a mean time of 7 months. Those presenting a mild improvement after a mean time of 2 months and those with a marked improvement after 4 months.

DHEA, DHEAS and PCOS.

2014

Approximately 20-30% of PCOS women demonstrate excess adrenal precursor androgen (APA) production, primarily using DHEAS as a marker of APA in general and more specifically DHEA, synthesis. The role of APA excess in determining or causing PCOS is unclear, although observations in patients with inherited APA excess (e.g., patients with 21-hydroxylase deficient congenital classic or non-classic adrenal hyperplasia) demonstrate that APA excess can result in a PCOS-like phenotype. Inherited defects of the enzymes responsible for steroid biosynthesis, or defects in cortisol metabolism, account for only a very small fraction of women suffering from hyperandrogenism or APA excess. Rather, women wi…

Bisphenol A Effects on the Growing Mouse Oocyte Are Influenced by Diet1

2009

Growing evidence suggests that exposure to bisphenol A (BPA) has the ability to disrupt several different stages of oocyte development. To date, most attention has focused on the effects of BPA on the periovulatory oocyte, and considerable variation is evident in the results of these studies. In our own laboratory, variation in the results of BPA studies conducted at different times appeared to correlate with changes in mill dates of animal feed. This observation, coupled with reports by others that dietary estrogens in feed are a confounding variable in studies of endocrine-disrupting chemicals, prompted us to evaluate the effect of diet on the results of BPA studies of the periovulatory o…

Locking Y Lateral Canthopexy as a Treatment for Dry Eye Disease Caused by Eyelid Malposition

2020

PURPOSE The signs and symptoms of dry eye disease (DED) can affect the quality of life of patients. This study analyzes whether locking Y lateral canthopexy improves patients' quality of life and in what way it does so (based on the ocular surface disease index questionnaire) and DED signs (measured by the fluorescein breakup time, tear osmolarity, Schirmer test, and corneal staining) in patients with DED caused by a eyelid malposition or impaired blink dynamics. METHODS This was a case-control study. Forty eyes of 20 patients with DED and lateral canthal disinsertion examined at the University Hospital La Ribera during a 1-year period from November 2016 to November 2017. The 40 eyes were d…

Acceptability, reach and implementation of a training to enhance teachers’ skills in physical activity promotion

2020

This is a pre-print of a published study: Renko, E., Knittle, K., Palsola, M. et al. Acceptability, reach and implementation of a training to enhance teachers’ skills in physical activity promotion. BMC Public Health 20, 1568 (2020). https://doi.org/10.1186/s12889-020-09653-x Background: In order to achieve real-world impacts, successful behavior change interventions need to be scaled up and broadly implemented. Implementation is challenging however, and the factors influencing successful implementation are not fully understood. This study describes the nationwide implementation of a complex theory-based program to promote physical activity and reduce sedentary behavior in vocational school…

Gegenüberstellung der Wertigkeit von Angioskopie, Angiographie und Sonographie zur Erfassung pathologischer Gefäßwandprozesse

1994

AIMS The ability of angioscopy, angiography and sonography to evaluate arteriosclerotic vascular lesions were compared to determine if angioscopy is a valuable addition in the diagnostic armamentarium. METHODS An in-vitro study was selected to enable microscopic assessment of the arteries. Angiography was followed by sonography and endoscopy and finally the vessels were evaluated macro- and microscopically. RESULTS The configuration of the vascular stenosis (plaque-shape, semicircular-eccentric, circular-concentric) was more reliably defined with angioscopy as compared to angiography and sonography. Intense calcification of plaque was detected sonographically with a high sensitivity (90%) u…

Intravaskuläre Sonographie: Erste klinische Ergebnisse

1991

Intravascular ultrasound is a new diagnostic modality which, for the first time, provides high resolution images of the vessel wall. 91 intraluminal ultrasound studies were performed in 50 patients during the course of 55 diagnostic and therapeutic catheterizations. A F-6 ultrasound catheter (20 MHz) was used. The method is an easily and rapidly performed addition to angiography. Changes in vessel walls (arteriosclerosis, dissection, tumour infiltration) can be readily diagnosed and their extent can be accurately described. The ability to determine luminal cross sectional area is particularly helpful for planning and performing therapeutic interventions.

The "neurologic hypothesis": A new concept in the pathogenesis of the endometriosis?

2005

To cartograph the retroperitoneal infiltration of deep-infiltrating endometriosis of the rectovaginal space, we report on 467 patients who underwent laparoscopic/vaginal surgery for deep-infiltrating adenomyosis of the rectovaginal space. Exact localisation of the locoregional extension and of secondary infiltrating localisation where noted. The cervix and the rectovaginal ligament were mostly involved, while isolated lesions of the rectovaginal space were very rare. Comparisons of the most involved sites show an absolute correlation with the anatomical repartition of the pelvic sympathetic nervous system. We postulate a new "neurologic theory" which could be one more explanation for the de…
