High-frequency rotational ablation following failed percutaneous transluminal coronary angioplasty.

1994

Percutaneous transluminal coronary angioplasty (PTCA) failed in 29 of 1,150 patients (2.5%) after successful passage of the guide wire. The reasons for failure were inability to pass the lesion with a balloon in 28 patients and inability to dilate the lesion in 1 patient. In these patients (15 stenoses and 14 chronic occlusions) rotational ablation was performed. We were able to pass the burr through the lesion in all of them, resulting in a reduction of diameter stenosis from 87 +/- 15 to 51 +/- 18%. Rotational ablation alone was initially successful (stenoses reduction > 20% and residual stenoses < 50%) in 15 of 29 (52%) patients. Additional PTCA was performed in 21 of 29 (72%) patients, …

Transmural myocardial ischaemia complicating recovery after dobutamine-atropine stress echocardiography in patients with non-significant coronary art…

2011

In the proposed selection of cases, traditional imaging is integrated with contemporary diagnostic tools available in the cath-lab to navigate the potential mechanisms underlying a very rare complication occurring in the recovery phase of dobutamine-atropine stress echocardiography. The data, collected in a time frame of nearly 15 years, provide interesting elements to possibly evolve from speculative considerations to plausible confirmation of the candidate pathophysiological mechanism mediating the occurrence of transmural myocardial ischaemia after beta-blockers administration.

The influence of advanced age and obesity on pregnancy course and outcome in patients with diabetes mellitus

2022

Introduction: Older women are at greater risk of suffering from a series of comorbidities such as obesity, diabetes, and hypertension that could negatively affect pregnancy course and outcomes. This study aims to investigate the impact of maternal age and pre-pregnancy body mass index (BMI) on pregnancy outcomes of women with diabetes mellitus (DM). Material and methods: The study included 323 diabetic pregnant women. All complications throughout pregnancy and the early neonatal period were noted. The women were divided into groups according to age decade and BMI. Results: 84.8% of women reported pregnancy complications, with a higher prevalence in obese women (p = 0.003). However, most chi…

Performance of QuantiFERON-TB Gold Plus for detection of latent tuberculosis infection in pregnant women living in a tuberculosis- and HIV-endemic se…

2017

We evaluated the performance of QuantiFERON-TB Gold Plus (QFT-Plus), which includes two Mycobacterium tuberculosis antigen formulations (TB1 and TB2), for detection of latent tuberculosis infection during pregnancy. Eight-hundred-twenty-nine Ethiopian pregnant women (5.9% HIV-positive) were tested with QFT-Plus, with bacteriological sputum analysis performed for women with clinically suspected tuberculosis and HIV-positive women irrespective of clinical presentation. QFT-Plus read-out was categorized according to the conventional cut-off (0.35 IU/ml) for both antigen formulations. In addition, we analysed the distribution of QFT-Plus results within a borderline zone (0.20–0.70 IU/ml), and i…

Formation of basement membrane in extracapillary proliferates in rapidly progressive glomerulonephritis

1977

In the extracapillary proliferations (crescents) of the glomeruli in glomerulonephritis, basement membranes appear and in addition "secretory bodies" are formed in the cisternae of the rough endoplasmatic reticulum. The findings permit the conclusion that proliferated visceral epithelial cells are involved in the crescent formation to a greater extent than previously assumed.

Multicentre evaluation of in vitro contracture testing with bolus administration of 4-chloro-m-cresol for diagnosis of malignant hyperthermia suscept…

2003

Background and objective The in vitro contracture test with halothane and caffeine is the gold standard for the diagnosis of susceptibility to malignant hyperthermia (MH). However, the sensitivity of the in vitro contracture test is between 97 and 99% and its specificity is 78-94% with the consequence that false-negative as well as false-positive test results are possible. 4-Chloro-m-cresol is potentially a more specific test drug for the in vitro contracture test than halothane or caffeine. This multicentre study was designed to investigate whether an in vitro contracture test with bolus administration of 4-chloro-m-cresol can improve the accuracy of the diagnosis of susceptibility to MH. …

Glycometabolic control in Acromegalic patients with Diabetes: a study of the effects of different treatments for GH excess and for hyperglycaemia.

2012

Background. Diabetes mellitus (DM) is frequently observed in patients with acromegaly. Current therapies for acromegaly may impact glucose regulation, influencing insulin sensitivity and secretion. The question whether these therapies modify control and progression of diabetes once present is still open. Aim. Aim of our study is to analyse glucose control in acromegalic patients with diabetes, evaluating the relation with treatments for GH excess and for diabetes. Methods. Seventy patients with acromegaly and diabetes were studied. Duration and treatments of acromegaly and DM were recorded, together with clinical and metabolic parameters. Results. Most patients (92.8%) were treated with som…

Plasma glycosphingolipids in diabetics and normals

1975

In diabetic patients with hyperlipoproteinemia type IV the monohexosyl ceramide concentration in blood plasma is significantly elevated. This augmentation can be attributed to an increased monohexosyl ceramide content of the BLDL plasma fraction. In contrast, the di-, tri-, the tetrahexosyl ceramide levels remain within normal limits. In normolipidemic diabetics of comparable age, sex, and weight classes and of comparable metabolic control no elevations of glycolipid fractions could be found. However, patients with primary hyperlipoproteinemia type IV show an increase of monohexosyl ceramide concentrations in blood plasma. Therefore, the augmentation of monohexosyl ceramide levels in plasma…

Diabetes known or newly detected, but not impaired glucose regulation, has a negative influence on 1-year outcome in patients with coronary artery di…

2006

Aims: Although diabetes is known to be a major contributor to cardiovascular diseases, as well as an independent predictor for adverse outcomes in patients with coronary artery disease (CAD), information on the prognosis of patients with CAD and newly diagnosed diabetes or impaired glucose regulation (IGR) is scarce. The objective of this study was to explore 1-year outcome in relation to different glucometabolic states of patients participating in the Euro Heart Survey on diabetes and the heart. Methods and results: In 4676 out of 4961 patients, information on the relation between 1-year outcome and glucometabolic state, which was based on oral glucose tolerance test (OGTT) or fasting gluc…
