Interaction of cerebrovascular disease and contralateral carotid occlusion in prediction of shunt insertion during carotid endarterectomy

2012

INTRODUCTION To assess the possible role and the interaction of cerebrovascular disease and vascular stenosis on the necessity of shunt insertion during carotid endarterectomy (CEA). MATERIAL AND METHODS Eighty consecutive patients undergoing CEA under regional anaesthesia were prospectively enrolled. Patients were divided into two groups depending on whether they were shunted or not. The measured end-points were co-morbidities degree of contralateral and carotid stenosis and other intra- and postoperative outstanding parameters. ANOVA, Student's t and χ(2) tests were used (p<0.05). Variables differing significantly between groups and potential confounders were used in backward stepwise log…

Nephrotoxicity of ibandronate and zoledronate in Wistar rats with normal renal function and after unilateral nephrectomy.

2015

A previous animal study compared the nephrotoxic effect of ibandronate (IBN) and zoledronate (ZOL), but interpretation of these study results was limited because of the model of minimal nephrotoxic dosage with a dosage ratio of 1:3. The present study investigated the nephrotoxicity of ibandronate and zoledronate in a 1.5:1 dose ratio, as used in clinical practice and compared the nephrotoxicity in rats with normal and with mildly to moderately impaired renal function. We compared rats with normal renal function (SHAM) and with impaired renal function after unilateral nephrectomy (UNX), treated either with ibandronate 1.5mg/kg, zoledronate 1mg/kg or placebo once (1×) or nine (9×) times. Rena…

Temporary warm ischaemia, 5/6 nephrectomy and single uranylnitrate administration — comparison of three models intended to cause renal fibrosis in ra…

2001

In patients the progression of pathologic renal processes after the treatment of primary disease is a problem of increasing importance and therapeutic strategies are insufficient till now. The aim of this paper was to search for rat models of interstitial fibrosis as a basis for testing therapeutic strategies to prevent end-stage renal failure. Experiments were done on adult female Wistar rats (Han:Wist) to investigate long-term consequences of temporary warm ischaemia, 5/6 nephrectomy (5/6 NX) and single uranyl nitrate (UN) administration (0.3 or 0.5 mg/ 100 g body wt. intraperitoneally). Observation time was 20 weeks after injury in each group. Creatinine clearance, urinary protein excret…

Transitional cell carcinoma of the renal pelvis presenting as a renal abscess.

2002

We report on a 76-year-old woman who was diagnosed with a primary renal abscess of the left kidney. After percutaneous drainage, no clinical improvement was observed. Surgical exploration and nephrectomy were performed. The histologic evaluation revealed an unsuspected transitional cell carcinoma of the renal pelvis, which had been misinterpreted as a primary renal abscess. Malignancy must be considered as an underlying cause for the formation of a renal abscess, especially if no other predisposing factors such as diabetes mellitus or urinary stones are present.

Ovarian cysts in the fetus and neonate--changes in sonographic pattern in the follow-up and their management.

1992

In a multicenter trial we retrospectively evaluated the clinical and sonographic data of 49 neonatal ovarian cysts, 44 of which were detected prenatally and 5 on the first day after delivery. Of the 44 prenatally detected cysts 39 were purely cystic, 5 echogenic or had a mixed pattern. In 20 patients the cystic appearance changed during delivery from purely cystic to a mixed pattern being independent on the size of the cyst. 26 of the 44 cysts were treated surgically. Salpingotorsion was found in 8 and was independent on the size of the cyst. In 15 a salpingo-oophorectomy or oophorectomy was performed, in 11 the ovary was saved. 23 patients were followed sonographically: 15 cysts showed com…

The Use of NFP When Pregnancy Is Contraindicated?

2020

The Sacred Congregation for the Doctrine of the Faith has declared the moral liceity of hysterectomy when certain medical criteria are met but does not exclude other options, “for example, recourse to infertile periods or total abstinence.” Consequently, there may be couples who prefer to use natural family planning (NFP) methods. We shall refer to these in this article. The efficacy of NFP methods is determined by knowing the day of ovulation. To that end, three parameters are used: the presence and consistency of cervical mucus, measurement of the basal body temperature, and the determination of particular hormones in urine. Of the NFP methods used, the so-called sympto-thermal method se…

Renal cell carcinoma with inferior vena cava involvement: Prognostic effect of tumor thrombus consistency on cancer specific survival

2016

Background Renal cell carcinoma forming a venous tumor thrombus (VTT) in the inferior vena cava (IVC) has a poor prognosis. Recent investigations have been focused on prognostic markers of survival. Thrombus consistency (TC) has been proposed to be of significant value but yet there are conflicting data. The aim of this study is to test the effect of IVC VTT consistency on cancer specific survival (CSS) in a multi-institutional cohort. Methods The records of 413 patients collected by the International Renal Cell Carcinoma–Venous Thrombus Consortium were retrospectively analyzed. All patients underwent radical nephrectomy and tumor thrombectomy. Kaplan–Meier estimate and Cox regression analy…

Surgical treatment of chronic thromboembolic pulmonary hypertension

1999

Background: Chronic thromboembolic pulmonary artery obstruction from unresolved pulmonary emboli is characterized by persistent elevation of pulmonary vascular resistance and progressive right heart dysfunction and failure. The diagnosis of chronic thromboembolic pulmonary hypertension is difficult and often missed. Medical therapy is ineffective in these patients. The prognosis is poor and depends on the degree of pulmonary hypertension. Pulmonary thromboendarterectomy has proven to be an effective and potentially curative surgical therapy for this clinical entity although less than 1000 cases have been reported in the surgical literature. Methods: The current principles of diagnosis, pati…

Kontrastmittelverstärkte dreidimensionale MR-Angiographie der Lungenarterien bei Patienten mit chronisch-rezidivierender Lungenembolie - Vergleich mi…

2000

Purpose: This study compares contrast-enhanced 3D-MR angiography (MRA) of the pulmonary arteries with selective intraarterial DSA in patients with chronic thromboembolic pulmonary hypertension. Materials and Methods: 20 patients preoperatively underwent a contrast-enhanced 3D-MRA of the pulmonary arteries at 1.5T using the phased-array body coil. For MRA, we used a 3D-Flash-sequence after bolus timing. 2 radiologists analyzed the acquired image material in consensus with respect to the detection of central thromboembolic material and the visualization of the pulmonary arterial tree. Finally, the MR angiograms were compared with selective DSA images using surgical findings as the definitive …
