Cell-mediated immunity (CMI) response to different antigens was examined in healthy women, in patients with cervical precancerous lesions, and in patients with cervical cancer. Cervical lesions were diagnosed by cytological (PAP) smears, from examination by colposcopy, and from "punch" biopsy material by histology. CMI response is related to specific processes in healthy and cancer cells. CMI was investigated by leukocyte adherence inhibition (LAI) assay using specific antigen (prepared from cervical carcinoma tissue) and non specific antigen (prepared from blood of mice infected by LDH--lactate dehydrogenase--virus). The CMI responses of healthy women and cancer patients to the antigens used are different: the majority of T lymphocytes display adherence and non adherence, respectively (but the CMI responses elicited by the antigens are not equal and small quantitative differences are observed). Regardless of the CIN (cervical intraepithelial neoplasia) grades, CMI responses correspond either to healthy women or to cervical carcinoma patients (at about similar ratio of cases in all the CIN groups). Effect of non specific antigen suggests that cervical carcinoma transformation may be connected with reduction of mitochondrial activity similar to processes in LDH virus infection.

Pregnancy-associated osteoporosis is a rare condition, which imposes multiple symptoms in the musculoskeletal system. Common complaints announced by patients are severe pain in the lower back, hips and the joints of the lower extremities with a reduced and less mobility status in general. Most of the patients' problems occur in the last trimester of pregnancy or postpartum and are often not diagnosed as side effects of osteoporosis but as problems associated with pregnancy. Although vertebral fractures are rare complications of pregnancy-associated osteoporosis, they should be always considered in women presenting with an acute pain syndrome in peripregnancy period. This case presents a 40-year-old primagravid woman who developed pain in hips and severe pain in the lower back causing an immobilization diagnosed with a pregnancy-associated osteoporosis with eight compression fractures in the thoracic and lumbar spine. Because of sagittal imbalance of the spine, she was treated with kyphoplasty at the four lumbar fractures and with bracing for the upper, thoracic ones, additional to the conservative anti-osteoporotic therapy. The authors discuss pregnancy-associated osteoporosis and its clinical presentation, as well as the indications of kyphoplasty, spinal alignment and the risk of single conservative treatment.

A case report of a patient with unusual compressive syndrome is reported herein. A 27-year-old woman was referred to our hospital due to intermittent claudication in the left thigh and calf which gradually developed over the last five months. Angiography showed an atypical short occlusion of the external iliac artery. Only surgical revision made an exact diagnosis. The formation compressing the artery was a ganglion that originated from the hip joint and adhered to the artery. Resection of the ganglion was carried out. The adjacent segment of the artery was removed and replaced by end-to-end venous graft using vena saphena magna. From the operation until present (30 months) the patient remains symptom-free. To our knowledge a hip joint ganglion compressing the artery and causing symptoms of peripheral arterial disease has not been previously reported in medical literature.

The presented case displays a clinical study of a cancer phenotype with a poor clinical outcome. Prediction of cancer development and effects of treatment at the beginning of the clinical stage is difficult as the knowledge of cancer process and all necessary parameters of the host body are limited. Cancer is mainly studied on the basis of biochemical-genetic processes and their morphological manifestation. However, the malignant process is assumed to be of essential biophysical nature and develops after mitochondrial dysfunction, which is a direct result of oncogene mutation. Cancers based on the normal and the reverse Warburg effect should be distinguished. The cancer tumors with the reverse Warburg effect display aggressiveness associated with a high rate of recurrence and metastatic implantation. Besides the nature of the two basic types of breast cancer tumors the outcome depends not only on their type, size, and site but also on reactions and interaction with the surrounding tissue and the body aptitude for metastatic activity connected with individual blood or lymphatic vessels for metastatic transport. It is necessary to assess all favourable and adverse factors for cancer development. General reliable method of their specification for all cancers is not available. Nevertheless, the main factor seems to be aggressiveness of cancer cells as follows from interpretation. To reveal the aggressive reverse Warburg effect tumors, metabolic biomarkers of the fibroblast stress should be examined.
