New frontiers in liver ultrasound: From mono to multi parametricity

2021

Modern liver ultrasonography (US) has become a "one-stop shop " able to provide not only anatomic and morphologic but also functional information about vascularity, stiffness and other various liver tissue properties. Modern US techniques allow a quantitative assessment of various liver diseases. US scanning is no more limited to the visualized plane, but three-dimensional, volumetric acquisition and consequent post-processing are also possible. Further, US scan can be consistently merged and visualized in real time with Computed Tomography and Magnetic Resonance Imaging examinations. Effective and safe microbubble-based contrast agents allow a real time, dynamic study of contrast kinetic f…

Interaction between muscle stiffness and stretch reflex sensitivity after long-term stretch-shortening cycle exercise

1998

The short latency stretch-reflex component (M1) and its interactions with muscle stiffness and with muscle performance were investigated before and after long-term stretch-shortening cycle (SSC) exercise. Dramatic fatigue induced reduction in maximal SSC performance capability, and electromyographic activity was accompanied by a consistent decrease in the M1 reflex component and eccentric peak stiffness of the muscle. It can be suggested, therefore, that the decreased muscle performance is not simply a direct effect of central or peripheral fatigue, but is partly due to impairment of the ability to utilize stiffness-related elastic energy.

Follow-Up and Relook Hysteroscopy

2020

Intra-uterine adhesions (IUAs) after initial treatment in patients with Asherman’s Syndrome are one of the main challenging issues in the gynecological practice, since its incidence has been increasing over the last few decades, with a reported recurrence rate up to 30%. Asherman syndrome is characterized by variable scarring inside the uterine cavity that can lead to partial or complete dysfunction of the endometrium with impairment of fertility and menstrual pattern (amenorrhea and hypomenorrhea).

Vorbereitung und Technik der operativen Behandlung von 225 Acetabulumfrakturen

1997

Between December 1986 and November 1995, 222 patients with 225 acetabular fractures were treated operatively by three surgeons in the Department of Traumatology and Emergency Surgery of the University Hospitals of the Catholic University of Leuven. Indications for surgery were unstable fracture, displaced fracture through the acetabular dome and fracture with intra-acetabular fracture fragments. There were 37.3% A-fractures, 49.7% B-fractures, and 13% C fractures according to the AO Classification. In 16.4% of fractures there were primary neurological deficits. Patients were treated operatively after an average of 5.0 days. The Kocher-Langenbeck approach was used in 56.9% of cases, the ilio…

Since little is known concerning the psychological, cognitive, and neurophysiological factors that are involved in and important for phases of prolonged breath-holding (pBH) in freedivers, the present study uses electroencephalography (EEG) to investigate event-related neurocognitive markers during pBH of experienced freedivers that regularly train pBH. The purpose was to determine whether the well-known neurophysiological modulations elicited by hypoxic and hypercapnic conditions can also be detected during pBH induced hypoxic hypercapnia. Ten experienced free-divers (all male, aged 35.10 ± 7.89 years) were asked to hold their breath twice for 4 min per instance. During the first pBH, a ch…

Inhibitory influences of vagal afferences on the oesophageal EMG peristaltic pattern

1987

AbstractThe influence of vagal afferents on the EMG peristaltic pattern was studied in pigeon oesophagus.Bilateral vagotomy did not abolish the primary peristalsis, but induced significant modifications of the peristaltic pattern parameters.Vagal afferent stimulation induced an inhibitory effect consisting of a temporary break or definitive block of the EMG peristaltic activity already in progress.Vagal afferent stimulation also induced a reduction of the spontaneous EMG activity and this effect was abolished either by glossopharyngeal bilateral section or ganglionic block.Likewise vagal afferent stimulation, the crop distension caused inhibitory effects on EMG peristaltic pattern. This eff…

PULMONARY AND CARDIAC COMPLICATIONS OF STAPHYLOCOCCAL OSTEOMYELITIS

1985

Pulmonary complications of staph.osteomyelitis seem to be infrequent and are seldom related in wide reviews of this entity and in texts of infectious diseases.Cardiac complications are still more infrequently found.However our experience is far from this observation. We have found pneumonic interstitial infiltrates and/or asymptomatic pneumatoceles in about two thirds of children suffering from staph. osteomyelitis to whom we have taken a weekly chest radiograph while they were feverish.Severe forms are rare.Lately,however,we have treated 5 children with acute staph.osteomyelitis,aged 6 to 13,and whith severe pulmonary and cardiac complications.They had broad bone lesions which affected (1)…

Robot-Assisted Transvesical Enucleation of Benign Prostatic Hyperplasia: Lessons from a Single Surgeon’s Learning Curve

2014

Abstract Introduction Open simple prostatectomy is a well-established and effective operation for prostate volumes greater than 80 gm but also associated with bleeding and urinary incontinence. To benefit from the advances of laparoscopy, robot-assisted simple prostatectomy was established. We determined the learning curve of this minimally invasive surgery by evaluating the first procedures by an experienced robotic surgeon. Methods Patients presenting for surgical therapy with prostate volumes greater than 80 gm were considered for the study. Evaluation included validated questionnaires preoperatively, and at 6 and 12 weeks postoperatively. Blood loss, transfusions, operation time and pad…

111-Indium-DTPA-Octreotid-Szintigraphie bei kolorektalen Lebermetastasen

1997

The somatostatin analogue octreotide is effective in the treatment of neuroendocrine and other tumours. 111-In-labelled DTPA-octreotide scintigraphy is successful in localizing primary neuroendocrine tumours and metastases and other tumours containing somatostatin receptors. An antiproliferative effect of octreotide was also demonstrated for colorectal carcinoma. Since only about 40% of colorectal carcinomas express somatostatin receptors, we tried to establish whether 111-In-labelled DTPA-octreotide scintigraphy is able to reveal the receptor status of liver metastases in patients with colorectal liver metastases. This would be useful in selecting patients for adjuvant therapy studies with…

Das Popliteaaneurysma: Klinik und Diagnostik

1995

PURPOSE To identify clinical and radiological features allowing an early diagnosis of popliteal aneurysms. MATERIAL AND METHODS History, clinical features and radiological findings of 23 patients with 37 aneurysms were reviewed. RESULTS 14 patients presented with a history of a sudden onset of rest pain localised in the calf or foot. Arteriography found popliteal artery occlusion in 12 of them. Amputation was necessary in one patient in spite of immediate diagnosis and therapy. In two cases embolisation of the tibial vessels caused intermittent claudication. In at least 7 patients the underlying disease was not suspected until arteriography was performed. In 16/23 patients the presence of t…
