Biomed Pap Med Fac Univ Palacky Olomouc Czech Repub. 2015, 159(1):001-011 | 10.5507/bp.2014.049

Adhesive interactions are vital for the persistence of both normal and malignant cells. Malignant cells trigger positive feedback loops causing adhesion molecule inflammatory overexpression. Disruption of adhesive interactions can overcome the high resistance to treatment and increase the selectivity of malignant cell targeting. Understanding adhesive interactions may underlie the basis of novel therapeutic approaches.

Lidao Bao, Ying Zhang, Guomin Wei, Yi Wang, Ruilian Ma, Rui Cheng, Xianhua Ren, Agula B

Biomed Pap Med Fac Univ Palacky Olomouc Czech Repub. 2015, 159(1):053-059 | 10.5507/bp.2013.096

This research article explores the impact of puerarin in the pathogenesis of atherosclerosis in experimental atherosclerotic rabbits. The findings were that puerarin significantly attenuated the initiation and development of atherosclerotic lesions. Puerarin had anti-atherosclerotic effects through decreased expression of proliferating cell nuclear antigen (PCNA) and platelet-derived growth factor A (PDGF-A). In this way, puerarin attenuated the migration and proliferation of vascular smooth muscle cells (VMSCs).

The ESBL- and AmpC-positive Enterobacteriaceae in the normal gastrointestinal tract (GIT) microflora are potential etiological agents whose high resistance to antibiotic treatment can lead to a failure of initial antibiotic therapy. Some authors do not consider monitoring of these strains as useful. However, our study identified two patients diagnosed with urinary tract and bloodstream infections caused by ESBL- or AmpC-positive Enterobacteriaceae from the GIT microflora. This is evidence that these strains can act as agents causing bacterial complications and in patients with hematological malignancies, it is advisable to regularly monitor the prevalence of both pathogenic multiresistant strains and potentially pathogenic strains found in GIT.

David Zeman, Pavel Hradilek, Pavlina Kusnierova, Radim Piza, Katarina Reguliova, Ivana Woznicova, Olga Zapletalova

Biomed Pap Med Fac Univ Palacky Olomouc Czech Repub. 2015, 159(1):104-113 | 10.5507/bp.2014.058

The sensitivity and specificity of CSF-restricted oligoclonal IgG and oligoclonal free light chains are compared for the ability to diagnose multiple sclerosis and other inflammatory neurological diseases. Optimal cut-off values for the number of CSF-restricted oligoclonal IgG and free light chain bands were analyzed; for oligoclonal IgG and free light chains, these cut-offs were found to be higher (≥4 IgG bands and ≥6 free κ bands) than the cut-off ≥2 bands usually reported so far. The general conclusion is that reporting borderline values as positive, compromises the specificity of these tests. The oligoclonal free light chain test may be valuable especially when the oligoclonal IgG test is negative or borderline.

Seventy-one patients at risk of heart failure with normal left ventricular ejection fraction underwent simultaneous exercise echocardiography and right heart catheterization. Fifty-one patients had exercise-induced pulmonary capillary wedge pressure (PCWP) elevation ≥ 8 mmHg and reached peak exercise PCWP ≥ 20 mmHg. Post-exercise recovery of PCWP at 1, 2, 3, 4, and ≥ 5 min was achieved in 7 (13.7%), 11 (21.6%), 10 (19.6%), 6 (11.8%), and 17 (33.3%) patients, resp. In summary, the course of post-exercise PCWP recovery is highly variable, and a significant proportion of patients have only a brief period (≤ 2 min) of exercise-induced PCWP elevation. This fact should be taken into account when assessing exercise-induced PCWP noninvasively.

Oldrich Chrapek, Barbora Jirkova, Vít Kandrnal, Jiri Rehak, Martin Sin

Biomed Pap Med Fac Univ Palacky Olomouc Czech Repub. 2015, 159(1):120-123 | 10.5507/bp.2013.015

In the treatment of central serous chorioretinopathy, we used the beta-blocker metipranolol. Metipranolol use is associated with possible adverse effects such as: indigestion, fatigue, weakness, malaise, headache, dizziness, insomnia, depression, itching, skin rash, visual disturbances, shortness of breath, slow heart rate and other heart rhythm disorders, low blood pressure , dryness of the conjunctiva. This study showed no benefit of metipranolol for the treatment of central serous chorioretinopathy. We believe that metipranolol is not appropriate for the treatment of patients with central serous chorioretinopathy, exposing them to the risk of the adverse events associated withmetipranolol.

Biomed Pap Med Fac Univ Palacky Olomouc Czech Repub. 2015, 159(1):135-138 | 10.5507/bp.2014.008

Proliferation is an independent prognostic factor in multiple myeloma. Increased activity of thymidine kinase in serum is associated with higher proliferation rate in multiple myeloma. Imaging methods such as 99mTc-MIBI scintigraphy and 18F-FDG PET/CT imagine active myeloma lesions and a positive result is a negative prognostic factor. Increased levels of serum thymidine kinase were observed in MIBI or PET/CT positive patients.Combination of increased levels of serum thymidine kinase and positive MIBI or PET/CT results are useful prognostic factors.

This is the first prospective study that compares the results (neurological deterioration, overall survival time) of resection and biopsy of glioblastoma (GBM) in eloquent brain areas (EBA). For patients in good clinical condition and for tumors in or near EBA, resection of the GBM (as radical as possible) is recommended.

Knowledge, attitudes and decision-making in Czech women with atypical results of prenatal screening tests for the most common chromosomal and morphological congenital defects in the fetus: Selected questionnaire results

Vladana Skutilova

Biomed Pap Med Fac Univ Palacky Olomouc Czech Repub. 2015, 159(1):156-162 | 10.5507/bp.2013.046

The paper describes the variables that can complicate compliance and decision-making in pregnant women coming for genetic counselling based on atypical screening of one of the screening tests, or an issue in personal or family history. This is the first study done in in the Czech environment. Among other things, lack of awareness and widespread confusion about screening and invasive tests were discovered, creating the distress that pregnant women here often unnecessarily experience.

Case reports

Secondary hypertension and hirsutism as a clinical manifestation of tumor duplicity

Zdenek Frysak, David Karasek, Igor Hartmann, Ladislava Kucerova

Biomed Pap Med Fac Univ Palacky Olomouc Czech Repub. 2015, 159(1):163-165 | 10.5507/bp.2013.056

Primary aldosteronism is a relatively common cause of secondary hypertension. Hyperandrogenic conditions tend to have their origin in the adrenal cortex. The authors report a very rare combination of adrenocortical adenoma as a source of overproduction of aldosterone and benign tumor of the ovary, as the source of testosterone production. The patient was completely healed by one laparoscopic procedure.
