Multimodal assessment of right ventricle overload-metabolic and clinical consequences in pulmonary arterial hypertension.

Background: In pulmonary arterial hypertension (PAH) increased afterload leads to adaptive processes of the right ventricle (RV) that help to maintain arterio-ventricular coupling of RV and preserve cardiac output, but with time the adaptive mechanisms fail. In this study, we propose a multimodal approach which allows to estimate prognostic value of RV coupling parameters in PAH patients.

Methods: Twenty-seven stable PAH patients (49.

Prognostic value of late gadolinium enhancement mass index in patients with pulmonary arterial hypertension.

Purpose: Dysfunction of the right ventricle (RV) is an important determinant of survival in patients with pulmonary arterial hypertension (PAH). The presence of late gadolinium enhancement (LGE) in cardiac magnetic resonance (CMR) at RV insertion points (RVIPs) has been found in majority of PAH patients and was associated with parameters of RV dysfunction. We hypothesize, that more detailed quantification of LGE may provide additional prognostic information.

Prognostic role of PET/MRI hybrid imaging in patients with pulmonary arterial hypertension.

Objective: Right ventricular (RV) function is a major determinant of survival in patients with pulmonary arterial hypertension (PAH). Metabolic alterations may precede haemodynamic and clinical deterioration. Increased RV fluorodeoxyglucose (FDG) uptake in positron emission tomography (PET) was recently associated with progressive RV dysfunction in MRI, but the prognostic value of their combination has not been established.

PET/MRI-guided GTV delineation during radiotherapy planning in patients with squamous cell carcinoma of the tongue.

Purpose: The aim of the study was to evaluate the usefulness and accuracy of 18-fluorine-labeled fluorodeoxyglucose (PET) and magnetic resonance imaging (MRI) hybrid in gross tumor volume (GTV) delineation during radiotherapy planning in patients with carcinoma of the tongue.

Methods: Ten patients with squamous cell carcinoma (SCC) of the tongue underwent computed tomography (CT) and PET/MRI examination. The GTV for primary tumor and lymph nodes (nGTV) were defined on CT (GTV-CT) and compared to GTVs obtained from PET (GTV-PET) and MRI (GTV-MRI) images.

Neuronal loss or dysfunction in patients with early Lyme neuroborreliosis: a proton magnetic resonance spectroscopy study of the brain.

Background: We hypothesized that since Borrelia burgdorferi causes systemic inflammation and infects the brain, it may lead to alterations in cerebral metabolism, as measured by H-magnetic resonance spectroscopy (H-MRS). The purpose of our study was to determine whether H-MRS could detect brain metabolite alterations in patients with early Lyme neuroborreliosis (LNB) in normal-appearing brain tissue on the conventional magnetic resonance imaging (MRI).

Methods: Twenty-six patients diagnosed with early LNB and twenty-six healthy volunteers as a control group have been involved in the study.

Proton magnetic resonance spectroscopy (H-MRS) of the brain in patients with tick-borne encephalitis.

Tick-borne encephalitis (TBE) is a disease caused by a tick-borne encephalitis virus (TBEV) belonging to the Flaviviridae family. The aforementioned virus is transmitted by the bite of infected ticks. In the recent years, TBEV has become a serious public health problem with a steady increase in its incidence, mainly due to the climate changes and spreading the infected ticks into new territories.

Evaluation of Imaging Methods in Tick-Borne Encephalitis.

Tick-borne encephalitis (TBE) is caused by a virus that belongs to the family and is transmitted by tick bites. The disease has a biphasic course. Diagnosis is based on laboratory examinations because of non-specific clinical features, which usually entails the detection of specific IgM antibodies in either blood or cerebrospinal fluid that appear in the second phase of the disease.

Systematic biobanking, novel imaging techniques, and advanced molecular analysis for precise tumor diagnosis and therapy: The Polish MOBIT project.

Personalized and precision medicine is gaining recognition due to the limitations by standard diagnosis and treatment; many areas of medicine, from cancer to psychiatry, are moving towards tailored and individualized treatment for patients based on their clinical characteristics and genetic signatures as well as novel imaging techniques. Advances in whole genome sequencing have led to identification of genes involved in a variety of diseases. Moreover, biomarkers indicating severity of disease or susceptibility to treatment are increasingly being characterized.

Cerebrovascular Manifestations of Lyme Neuroborreliosis-A Systematic Review of Published Cases.

Background: Lyme neuroborreliosis (LNB) is a disease caused by spirochete , involving the nervous system. It usually manifests as lymphocytic meningoradiculitis, but in rare cases, it can also lead to cerebrovascular complications. We aimed to perform a systematic review of all reported cases of LNB complicated by central nervous system vasculitis and stroke or transient ischemic attack (TIA).

Value of direct radionuclide cystography in diagnosing vesico-peritoneal fistulae.

A 36-year-old female patient underwent a laparoscopic surgery to remove a uterine fibroid. The procedure failed to relieve the pelvic pain, although its nature changed. After a period of observation, the patient was re-admitted to hospital on suspicion of a vesico-uterine fistula to be differentiated with endometriosis.

Calculation of therapeutic activity of radioiodine in Graves' disease by means of Marinelli's formula, using technetium (Tc) scintigraphy.

The therapeutic activity of I administered to patients with Graves' disease can be calculated by means of Marinelli's formula. The thyroidal iodine uptake (IU) needed for the calculation is usually determined with the use of I. The purpose of the paper was to estimate IU on the basis of technetium uptake in the thyroid at 20 min (TcU).

Single, very low dose (0.03 mg) of recombinant human thyrotropin (rhTSH) effectively increases radioiodine uptake in the I-131 treatment of large nontoxic multinodular goiter.

Background: Radioiodine therapy (RIT) in patients with large nontoxic multinodular goiter (MNG) recently becomes more common method in comparison to surgery (especially in elderly patients and with contraindications because of severe chronic diseases other systems). Repeatedly low thyroid radioactive iodine uptake (RAIU) decreases effectiveness of RIT or makes it impossible. The recombinant human thyrotropin can increase RAIU and improve the results of RIT.

Scientific Meeting Report Radiosynovectomy--radionuclide treatment of synovitis in the peripheral joints.

On 25 February 2012, an interdisciplinary scientific meeting on the Radiosynovectomy of Peripheral Joints (RPJ) was held in a lecture hall of Nukleomed clinic in Warsaw.

E-selectin, L-selectin, ICAM-1 and IL-6 concentrations changes in the serum of patients with hyperthyroidism in the early period of radioiodine I-131 therapy.

Background: Among cytokines- interleukins: -6 and -8 (IL-6, IL-8) and E-selectin (E-sel.), L-selectin (L-sel.) and intercellular cell adhesion molecule-1 (ICAM-1) are the most important links in the initiation of the inflammatory process.

[Clinically non-symptomatic pulmonary embolism in patients with deep vein thrombosis of the lower limb].

The pulmonary embolism (PE) is the common and severe complication of the deep vein thrombosis of the lower limbs. The lack of accurate diagnosis of PE is a cause of 5-10% of the hospital deaths. The aim of the study was to assess the incidence of the pulmonary embolism in patients with the deep vein thrombosis of the lower limbs with no clinical symptoms of pulmonary embolism.

[Contemporary role of scintigraphy in diagnosis, and evaluation of radioiodine therapy for treatment of thyroid diseases].

The paper presents a short historical outline and contemporary use of scintigraphic studies of thyroid gland. Appropriate recommendations and correct interpretations of the results of routine thyroid scans and the usefulness of other scintigraphic studies with 111In-octreoscan, 99mTc-MIBI, 99mTc-DMSA, 18FDG and radiolabeled monoclonal anti-carcinoembryonic antigen antibodies were discussed in the light of the present thyroid diagnostic studies. Particular attention was paid to the dependence of the scintigraphic thyroid images upon the thyroid-stimulating hormone (TSH) level in the patient's serum.
