background: pregnancy associated osteoporosis (pao) can lead to serious difficulties such as fragility fractures, elongated back pain and height loss in affected women. soluble receptor activator of nuclear factor-kappa b ligand (srankl) to osteoprotegerin (opg) ratio is chosen as a bone metabolism equation in many bone diseases characterized by bone resorption, such as post-menopausal osteopor...

BACKGROUND Percutaneous transcatheter patent foramen ovale (PFO) closure is now standard practice and may limit embolic complications for at least 10 years. Implantable PFO closure devices may be complicated by thrombosis, infection, device fracture, or embolization. A novel strategy uses radiofrequency-based thermal energy to seal PFO membranes, with no implanted device. We successfully used t...

The thermal conductivity, thermal diffusivity and heat capacity per unit volume of dunite rocks taken from Chillas near Gilgit, Pakistan have been measured simultaneously using transient plane source technique. The temperature dependence of thermal transport properties is studied in the temperature range 83-303 K. Different relations for the estimation of thermal conductivity are also tested. T...

Overheating is constantly mentioned as a risk factor for bone necrosis that could compromise the dental implant primary stability. Uncontrolled thermal injury can result in a fibrous tissue, interpositioned at the implant-bone interface, compromising the long-term prognosis. The methods used to record temperature rise include either direct recording by thermocouple instruments or indirect estim...

Bronchoscopic phototherapy is available now for 2 distinct categories of tracheobronchial cancer: roentgenographically occult superficial squamous cell carcinoma and advanced malignancy causing significant airway obstruction. Laboratory and clinical experience show that the photodynamic effect of hematoporphyrin derivative phototherapy (HpD-PT) may be useful for treating superficial cancers tha...

Low-energy, pulsed electromagnetic jields (PEMFs) have reversed therapeutically resistant pathologic processes in the musculo-skeletal system. Their development as a non-thermal therapeutic agent is based on 30 years of study of the electro-biological properties of connective tissues. Specijic energy characteristics in applied PEMFs produce selected biological effects by modifying synthetic and...

High intensity focused ultrasound (HIFU) is a promising technology for cancer treatment. Thereby, heating due to the focusing of the ultrasound non-invasively destroys the tumors. At the present state, the method is clinically restricted to uterine fibroids, adenomyosis, bone metastasis and prostate cancer. In abdominal organs as e.g. the liver, the motion due to breathing causes problems for t...

Background: Hepatitis activity index (HAI) and fibrosing stage are two important findings during the evaluation of liver samples in patients with chronic hepatitis B. The aim of this study was to determine the HAI and fibrosing stage in patients with anti-HBe positive chronic hepatitis B. Methods: Liver biopsy slides of 72 patients were evaluated at the Department of Pathology in two teaching ...

We present three young men who sustained closed diaphyseal fracture of the tibia and later developed severe osteocutaneous necrosis induced by heat during intramedullary reaming. They all had a narrow medullary cavity and in all a tourniquet had been used. Each developed a pretibial cutaneous blister soon after operation. In the following month severe osteomyelitis ensued, requiring segmental r...
