Ovarian Cancer Staging-How CT Scan Descriptions Differ from Surgical Findings.

Ovarian cancer is one of the most common causes of cancer death in women worldwide. Most often, it is detected in an advanced stage due to its insidious onset and lack of symptoms in stages I and II. That is why imaging diagnostics is so important.

The Analysis of ECE1 and PPARG Variants in the Development of Osteopenia and Osteoporosis in Postmenopausal Women.

Osteoporosis is a multifactorial systemic skeletal disease that is characterized by a low bone mineral density (BMD) and the microarchitectural deterioration of bone tissue, leading to bone fragility. The search for new genes that may play an important role in the regulation of bone mass and the development of osteoporosis is ongoing. Recently, it was found that altering the activity of the endothelin-1-converting enzyme encoded by the gene may affect bone mineral density (BMD).

Clinical Consequences of Unreconstructed Pelvic Defect Caused by Osteosarcoma with Subsequent Progressive Scoliosis in a Pediatric Patient-Case Report.

Osteosarcoma is the most common primary malignant bone tumor in children and adolescents. The standard and most effective treatment is wide resection of the tumor combined with neoadjuvant chemotherapy. Adolescent idiopathic scoliosis (AIS) is a genetically determined three-dimensional spinal deformity, which occurs in teenage patients and is mostly progressive.

Osteoprotegerin Gene as a Biomarker in the Development of Osteoporosis in Postmenopausal Women.

Osteoporosis is a multifactorial and polygenic disease caused by an imbalance between osteoclastogenesis and osteoblastogenesis, leading to a decrease in bone mineral density and the occurrence of disorders in the microarchitecture and metabolism of bone tissue. In postmenopausal women, there is a significant decrease in the production of estrogens, which play a key role in maintaining proper bone mineral density. Estrogens have an inhibitory effect on the development and activity of osteoclasts by reducing the synthesis of pro-resorption cytokines and stimulating the expression of osteoprotegerin (OPG).

Analysis of the Polymorphisms and Expression Levels of the BCL2, BAX and c-MYC Genes in Patients with Ovarian Cancer.

Ovarian cancer (OC) is one of the biggest problems in gynecological oncology and is one of the most lethal cancers in women worldwide. Most patients with OC are diagnosed at an advanced stage; therefore, there is an urgent need to find new biomarkers for this disease. Gene expression profiling is proving to be a very effective tool for exploring new molecular markers for OC patients, although the relationship between such markers and patient survival and clinical outcomes is still elusive.

The influence of ESR1 polymorphisms on selected hormonal, metabolic and mineral balance markers in women with hyperandrogenism.

Hyperandrogenism is the most common endocrine disorder in women, characterized by an imbalance in normal estrogen and androgen levels in the blood. Androgens influence bone mineral density, body mass composition, muscle mass, mental state, and the regulation of sexual function..

The Role of Forkhead Box O in Pathogenesis and Therapy of Diabetes Mellitus.

Type 2 diabetes is a disease that causes numerous complications disrupting the functioning of the entire body. Therefore, new treatments for the disease are being sought. Studies in recent years have shown that forkhead box O (FOXO) proteins may be a promising target for diabetes therapy.

Rhabdomyosarcoma of the Cervix in a Post-Menopausal Woman-An Unparalleled Phenomenon.

Rhabdomyosarcoma of the cervix is a soft tissue sarcoma that usually occurs in young women. It is very rare in adulthood. We discuss symptoms, the process of diagnosis of rhabdomyosarcoma embryonale of the cervix in a 61-year-old women and differences in treatment dependent on patient's age.

Preliminary Results of Highly Injectable Bi-Phasic Bone Substitute (CERAMENT) in the Treatment of Benign Bone Tumors and Tumor-like Lesions.

Background: CERAMENT™|BONE VOID FILLER is an injectable and moldable ceramic bone substitute material intended for bone voids. The material consists of hydroxyapatite and calcium sulfate hemihydrate. The aim of this study is to present the first long-term results following open curettage of benign bone tumors and tumor-like lesions and void filling with this novel injectable and synthetic bone graft.

From ophthalmologist to dentist via radiology.

Background: The aim of this paper was to analyze the causes of orbital cellulitis in connection with covert dental changes as well as to establish the role of radiological procedures in the final diagnosis and further treatment of such cases.

Material/methods: Thirty-two patients, aged 25-56, 22 women and 10 men were diagnosed and treated between January 2007 and April 2011 at the Pomeranian Medical University in Szczecin. The patients were examined in the infirmary of the ophthalmological department due to unilateral blepharo-oedema, abrupt pain and vision disturbances; in 5 cases, body temperature increased up to 37.

[Clinical and radiological evaluation of malignant metaplasia of benign primary bone tumors on the material of University Orthopaedic Department of Szczecin between 2002-2007].

The study presents clinical and diagnostic problems in patients with malignant bone metaplasia. Material is composed of 13 patients treated surgically between april 2002 and august 2007. In three cases tumors were localised in tibia, in 5 patients around distal femur, in 2 in pelvis, in 2 in humerus and in 1 in lumbar spine.

Polymorphism in the P-glycoprotein drug transporter MDR1 gene in renal transplant patients treated with cyclosporin A in a Polish population.

P-glycoprotein (P-gp), the product of MDR1 gene, is a protein which mediates transmembrane transport of a great number of xenobiotics including cyclosporin A used as an immunosuppressive drug in patients with allogenic kidney grafts. The P-gp activity and expression is dependent on the MDR1 gene polymorphism in position C3435T of exon 26. In this study, C3435T polymorphism was analyzed in 116 patients with allogenic kidney graft treated with cyclosporin Aand 144 randomly selected healthy individuals.

Peripheral blood lymphocytes P-glycoprotein (P-gp, gp-170) expression in allogenic kidney transplant patients.

Aim And Methods: P-glycoprotein (gp-170, P-gp) is a transmembrane transporter involved in drug, for example cyclosporine A, efflux from the cells thus limiting their intracellular concentration. Expression of the transporter on the surface of immune competent cells may be associated with poor prognosis in kidney transplant patients. The aim of the present study was to evaluate P-gp expression on the surface of CD4(+), CD8(+), CD19(+) and CD56(+) cells in kidney transplant patients treated with cyclosporine A as a main immunosuppressant, using flow cytometry.

MDR1 gene polymorphism in allogeenic kidney transplant patients with tremor.

P-glycoprotein (P-gp), an ATP-dependent efflux pump, is a membrane protein encoded by MDR1 gene, which demonstrates functional polymorphism. It is present in endothelial cells of the blood-brain barrier. P-gp pays a role in transmembrane transport of various xenobiotics, thus limiting their accumulation in the central nervous system.
