Acute pancreatitis as a risk factor of chronic pancreatitis and pancreatic cancer. An overview

David Solil, Petr Dite, Michal Senkyrik, Martina Bojkova, Bohuslav Kianicka

Biomed Pap Med Fac Univ Palacky Olomouc Czech Repub. 2024, 168(4):284-287 | DOI: 10.5507/bp.2024.023

Early diagnosis of pancreatic cancer and successful treatment is difficult. The optimization strategy is linked to identifying the specific subgroups of pancreatitis. To improve prognosis, it is crucial to identify patients at risk, in other words patients following acute pancreatitis and those with recurrent acute pancreatitis. The risk for pancreatic cancer development is very high in patients who are positive for other risk factors such as obesity, metabolic syndrome, alcohol abuse, smoking etc.

Long-term outcomes of bipolar transurethral enucleation and resection of the prostate on patients with benign prostatic obstruction: a 10-year follow-up

Peijie Chen, Peng Xu, Chunxiao Liu

Biomed Pap Med Fac Univ Palacky Olomouc Czech Repub. 2023, 167(4):340-346 | DOI: 10.5507/bp.2022.034

This 10-year follow-up indicates that B-TUERP is a safe and highly effective treatment for symptomatic BPH with lower reoperation rates. UDS value plays an important role in the preoperative judgment of surgical indications and the prediction of postoperative effect. Age, OABSS, PSA, MCC and DO may be critical predictors for urge incontinence after B-TUERP.

Serum concentrations of 25-OH vitamin D and the pro-inflammatory interleukins IL-17, IL-23, and IL-18 in patients with plaque psoriasis

Maria Ganeva, Zhivka Tsokeva, Tanya Gancheva, Evgeniya Hristakieva, Vanya Tsoneva, Irena Manolova

Biomed Pap Med Fac Univ Palacky Olomouc Czech Repub. 2024, 168(2):124-131 | DOI: 10.5507/bp.2023.043

The IL-23/IL-17 pathogenic axis plays a key role in the pathogenesis of psoriasis. Vitamin D is thought to be involved in the development of many diseases by modulating the inflammatory process. The study established a moderate negative correlation between 25(OH)D levels and the PASI score suggesting participation of vitamin D in the pathogenesis of psoriasis. Significantly higher concentrations of pro-inflammatory IL-17A and IL-18 in individuals with cardio-metabolic diseases (CMDs) in the study cohort and elevated levels of these cytokines in psoriasis patients with CMDs were detected.

A severe case of pemphigoid gestationis persisting after labour - case report and review of the literature

Hynek Herman, Petr Krepelka, Adela T. Faridova, Klara Trojanova, Jiri Hanacek, Barbora Jaluvkova, Jaroslav Feyereisl, Spyridon Gkalpakiotis

Biomed Pap Med Fac Univ Palacky Olomouc Czech Repub. 2024, 168(3):271-275 | DOI: 10.5507/bp.2023.010

The communication on pemphigoid gestationis is of paramount importance not only because of the need to report such a serious disease in a professional journal, but also as a recommendation for possible treatment of this rare condition in pregnancy which a large number physicians and especially obstetricians may not encounter in their entire careers. As with other diseases, early and accurate diagnosis and subsequent early therapy is of primary importance, to obviate major deterioration in the condition, the risk to the pregnant woman and the fetus, and to the newborn after delivery.

Differentiated modulation of signaling molecules AMPK and SIRT1 in experimentally drug-induced hepatocyte injury

Lea Njeka Wojnarova, Nikolina Kutinova Canova, Mahak Arora, Hassan Farghali

Biomed Pap Med Fac Univ Palacky Olomouc Czech Repub. 2023, 167(1):50-60 | DOI: 10.5507/bp.2022.018

The study originality consists in the use of mutual combinations of AMPK and SIRT1 activators and inhibitors in well-established experimental model of drug/acetaminophen-induced primary rat hepatocyte injury. Unlike others, the results suggest that SIRT1-mediated hepatoprotective effects could be partially AMPK independent providing the differentiated modulation of AMPK and SIRT1 activity for hepatocyte injury treatment.

Hypertension, hyperlipidaemia and thrombophilia as the most common risk factors for retinal vein occlusion in patients under 50 years

Zuzana Schreiberova, Jiri Rehak, Barbora Babkova, Martin Sin, Martina Rybarikova, Barbora Paskova, Irena Sinova, Petra Hubnerova, Miroslava Maluskova, Klara Maresova, Marta Karhanova

Biomed Pap Med Fac Univ Palacky Olomouc Czech Repub. 2024, 168(1):44-49 | DOI: 10.5507/bp.2022.036

The authors confirmed that the most common abnormalities leading to retinal vein occlusion (RVO) in patients under 50 years were systemic cardiovascular diseases, particularly arterial hypertension and hyperlipidaemia, and we found out that the risk factors for central RVO (CRVO), hemi-central RVO (HRVO) and branch RVO (BRVO) were similar. To the best of our knowledge, this is the only study to date which has examined the difference between RF presence in CRVO and HRVO patients compared to BRVO patients under the age of 50.

Biomed Pap Med Fac Univ Palacky Olomouc Czech Repub. 2024, 168(2):181-186 | DOI: 10.5507/bp.2022.051

Two cases of BCG pneumonitis described in this study highlight the necessity to consider systemic BCG infection in patients after intravesical BCG therapy. Uncommon complications of bacillus Calmette-Guérin administration could be very serious and threaten the life of patients treated with this modality. Treatment with specific antituberculotic medication underlines the importance of correct diagnosis.

Postcovid Guillain-Barré syndrome with severe course - case series two patients including clinical evaluation of smell and examination of olfactory event-related potentials (OERPs)

Nikola Pastorkova, Karla Janouskova, Libor Vasina, Helene Schulz, Jaromir Astl, Richard Holy

Biomed Pap Med Fac Univ Palacky Olomouc Czech Repub. 2024, 168(4):354-358 | DOI: 10.5507/bp.2023.014

This work presents case reports of two patients with Guillain-Barré syndrome associated with previous COVID19 that both patients survived. The sense of smell was investigated subjectively using sniffin' stick tests and objectively using objective olfactometry by the evaluation of olfactory event-related potentials (OERPs). Despite the severe course of post-covid GBS, no olfactory disturbance was detected. Both patients had good results on the smell tests. OERPs were plentiful in both cases.

Catheter ablation for non-paroxysmal atrial fibrillation. A review

Sabri Hassouna, Pavel Osmancik

Biomed Pap Med Fac Univ Palacky Olomouc Czech Repub. 2024, 168(1):1-14 | DOI: 10.5507/bp.2023.053

Atrial fibrillation (AF) is the most common cardiac arrhythmia and it is associated with increased morbidity and mortality. Catheter ablation is currently the most effective treatment for AF. PVI as a treatment for paroxysmal atrial fibrillation (AF) is associated with a high success rate; however, outcomes for treating persistent and long-standing persistent AF with PVI alone are substantially lower. Since pulmonary vein isolation by itself is rarely sufficient in the treatment of non-paroxysmal AF, a variety of techniques have been developed to increase the efficacy of CA for non-paroxysmal AF. Different approaches include PVI-only, PVI + linear ablations, and a stepwise approach, depending on the surgeon's skills, preference, and experience. New methods such as pulsed-field ablation, using ultra-short electrical pulses, appear to be very promising.

The inhibitory effects of Xiao-Gao-Jiang-Zhuo-containing serum on adipogenesis in 3T3-L1 preadipocytes

Liang Chen, Yu Han, Jing Li, Chunpeng Feng, Chen Chen, Ting Ye

Biomed Pap Med Fac Univ Palacky Olomouc Czech Repub. 2024, 168(1):25-34 | DOI: 10.5507/bp.2023.016

XGJZ-containing serum was obtained from obese rats treated with the XGJZ formula. The authors confirmed that XGJZ-containing serum can inhibit the differentiation of 3T3-L1 adipocytes, reduce the expression of lipogenic transcription factors, lipid accumulation, and lipid metabolism-related enzyme activity in differentiated 3T3-L1 adipocytes, thereby improving the risk of obesity and obesity-related diseases. It provides evidence for the mechanism of obesity

High pre-transplant Mucosal Associated Invariant T Cell (MAIT) count predicts favorable course of myeloid aplasia

Ivana Karlova Zubata, Jitka Smetanova Brozova, Tomas Karel, Barbora Bacova, Jan Novak

Biomed Pap Med Fac Univ Palacky Olomouc Czech Repub. 2024, 168(2):139-146 | DOI: 10.5507/bp.2023.011

MAIT cell abundance detected before myeloablative conditioning and autologous stem cell transplantation predicts the course of myeloid aplasia. The number of MAIT cells negatively correlated with peak C-reactive protein level and the amount of red blood cell transfusion units resulting in earlier discharge of patients with the most abundant MAIT cells.

Gamma-glutamyltransferase-associated glycoprotein patterns in human seminal plasma of normozoospermic men: a new aspect of biomarker heterogeneity

Tamara Jankovic, Jelena Danilovic Lukovic, Sanja Goc, Ninoslav Mitic, Ljiljana Hajdukovic, Miroslava Jankovic

Biomed Pap Med Fac Univ Palacky Olomouc Czech Repub. 2024, 168(4):319-325 | DOI: 10.5507/bp.2023.031

Gamma-glutamyltransferase (GGT) is implicated in a variety of diseases, but it is not extensively studied in relation to reproductive physiology. An increase in GGT activity is associated with alterations in a specific fractional pattern of distinct molecular mass forms. In this study, seminal GGT forms were estimated and, for the first time, annotated with underlying patterns of sialylated and mannosylated glycoproteins. The GGT-associated glycoprotein patterns were established as an adjunct reference parameter to differentiate between known GGT molecular mass forms. These emerge as new targets for evaluation of its biomarker potential.

The nociceptive response during adult cardiac surgery measured by the qNOX index: A feasibility study

Vladislav Rogozov, Tomas Vanek, Marek Maly, Jan Rocek, Petr Kacer

Biomed Pap Med Fac Univ Palacky Olomouc Czech Repub. 2024, 168(1):62-67 | DOI: 10.5507/bp.2022.045

The "qNOX" index for the Conox monitor was predicted to be responsive to the probability of reaction to nociceptive stimulation during general anaesthesia. The results show that the qNOX index does not reflect development of detectable signs related to nociceptive stimulation during adult cardiac surgery and could be affected by simultaneous use of muscle relaxants.

Ivana Mikoviny Kajzrlikova, Jan Kuchar, Petr Vitek, Barbora Horavova, Hana Vankova, Martin Chrostek

Biomed Pap Med Fac Univ Palacky Olomouc Czech Repub. 2024, 168(1):92-96 | DOI: 10.5507/bp.2022.043

This case report details the diagnostic work-up in a young woman with clinical presentation of heterotopic pancreas. Here, imaging and endoscopic findings of a newly diagnosed submucosal mass in the gastric antrum are well described. Technical issues of endosonographically-navigated drainage of symptomatic fluid collection in heterotopic pancreas with a plastic double pigtail stent under fluoroscopic control are also presented. Fluid collections after acute pancreatitis in heterotopic pancreas can be successfully managed by endoscopy.

Severe congenital T-lymphocytopenia may affect the outcome of neonatal intensive care

Ivana Hulinkova, Veronika Medova, Andrea Soltysova, Veronika Dobsinska, Andrej Ficek, Peter Ciznar

Biomed Pap Med Fac Univ Palacky Olomouc Czech Repub. 2024, 168(3):235-242 | DOI: 10.5507/bp.2023.028

This study evaluated the amount of TREC in a group of risk newborns and found a significant association between low TREC values and the occurrence of sepsis. The authors identified an association between mortality in preterm neonates with sepsis in patients with TREC < 5th percentile and they hypothesize that low TREC values may be a surrogate marker for mortality in preterm neonates.

The renoprotective effect of Tibolone in sepsis-induced acute kidney injury

Ejder Saylav Bora, Duygu Burcu Arda, Oytun Erbas

Biomed Pap Med Fac Univ Palacky Olomouc Czech Repub. 2024, 168(4):311-318 | DOI: 10.5507/bp.2024.016

This study breaks new ground by investigating Tibolone’s potential as a therapeutic agent in sepsis-induced acute kidney injury (AKI), an area largely unexplored previously. By delving into Tibolone’s effects on biomarkers like SIRT1 and YAP, as well as its impact on inflammatory and oxidative processes, it sheds light on its promising role in mitigating renal damage. The findings underscore Tibolone’s potential as a novel intervention for sepsis-associated AKI, urging further research for translational application in clinical settings.

Combination of plant phenolics and isoquinolinium alkaloids protects gingival fibroblast and improves post-extraction healing after lower third molar extraction

Karin Chytilova, Adela Galandakova, Katerina Valentova, Peter Tvrdy

Biomed Pap Med Fac Univ Palacky Olomouc Czech Repub. 2023, 167(2):131-138 | DOI: 10.5507/bp.2021.055

Inflammatory periodontal diseases are related to dental plaque formation and are influenced by its microbial composition and the host immune system. The dry socket (alveolar osteitis), which may occur as an inflammatory complication after third molar extraction, is similar in many ways. For this reason, efforts are currently underway to formulate preparations that inhibit dental plaque formation and suppress inflammation. The results of this pilot study show that the combination of the phenolic fraction of Lonicera caerulea fruit and Macleaya cordata alkaloids has beneficial effects on antioxidant imbalance and inflammation both in vitro and in a clinical study.

Macrotroponins cause discrepancy in high-sensitivity examination

Pavel Broz, Jaroslav Racek, Pavel Prokop, Jaroslav Novak, Daniel Rajdl, Ladislav Trefil

Biomed Pap Med Fac Univ Palacky Olomouc Czech Repub. 2024, 168(2):187-190 | DOI: 10.5507/bp.2023.001

This work presents two cases of a discrepancy between clinical presentation and falsely elevated cardiac troponins concentrations. Cases like this are well known to laboratory professionals, however, according to the experience of the authors, clinical professionals are often not. Presentation of such cases to the wider medical community can help avoid unnecessary investigation and possible harm to patients.

Utility of fine-needle aspiration biopsy (FNAB) in parotid pleomorphic adenoma diagnosis and management

Alzbeta Fikova, Stepan Novak, David Kalfert, Martin Kuchar, Michal Zabrodsky, Lucie Dostalova, Jan Balko, Jan Plzak

Biomed Pap Med Fac Univ Palacky Olomouc Czech Repub. 2024, 168(2):156-161 | DOI: 10.5507/bp.2023.027

The results confirmed, that ultrasound-guided fine-needle aspiration biopsy (FNAB) is valuable in the diagnostic algorithm for patients with pleomorphic adenoma. Ultrasound-guided FNAB is simple, accurate and valuable in the diagnosis of plemorphic adenoma and provides results that can lead to the choice of less invasive operative treatment. For smaller tumours in favourable locations, extracapsular dissection is a safe and adequate surgical technique with minimal risk to the facial nerve or other local complications and without increased risk of recurrence.

Fetal magnetic resonance imaging in the confirmation of congenital anomalies found on routine mid-trimester ultrasound

Ishraq Dhaifalah, Marek Godava, Jana Havalova, Pavla Hanzlikova, Kamila Michalkova, Lenka Bakaj Zbrozkova, Jakub Civrny, Howard Cuckle

Biomed Pap Med Fac Univ Palacky Olomouc Czech Repub. 2024, 168(4):326-331 | DOI: 10.5507/bp.2024.008

Most pregnant women are offered a routine ultrasound scan during the second trimester of pregnancy in order to detect fetal anomalies. In some cases, an anomaly suspected by ultrasound requires referral for a fetal magnetic resonance imaging (MRI) examination in order to clarify the diagnosis. In this study a large series of such referrals was assessed, accounting for one in six women with a fetal anomaly on ultrasound. In general, the MRI findings supported the scan results but this varied according to the type of anomaly. This concordance was very high for anomalies of the urinary tract and face.

Clinical presentation and pulmonary function tests in post-acute COVID-19 patients

Samuel Genzor, Petr Jakubec, Milan Sova, Jan Mizera, Pavol Joppa, Radim Burget, Pavol Pobeha

Biomed Pap Med Fac Univ Palacky Olomouc Czech Repub. 2023, 167(2):185-191 | DOI: 10.5507/bp.2022.039

This is an analysis of post-acute COVID symptoms and the pulmonary function test (PFT) results in patients surviving the native strain of the virus (Wuhan variant). There were 785 subjects (345 male) mean age 53.8 (SD 14.6); PFT results showed a decrease with disease severity; anosmia during the acute phase was associated with mild course of the disease, persisting dyspnoea was more frequent in the more severe disease groups; female sex was identified as a possible risk factor for persisting symptoms in the post-acute phase.

Changes in vascular density in the macula after pars plana vitrectomy for idiopathic macular hole with macular peeling and one type of flap

Anna Tarkova, Nada Jiraskova, Jaroslava Dusova, Jan Marak, Jan Studnicka

Biomed Pap Med Fac Univ Palacky Olomouc Czech Repub. 2024, 168(3):248-255 | DOI: 10.5507/bp.2023.017

In this study, the authors focused on changes in the vascular density of the superficial and deep vascular plexus in temporal and foveal-sparing flap after pars plana vitrectomy (PPV) with macular peel. The vascular density of the deep plexus increased in both groups and the vascular density of the superficial plexus was almost the same in the temporal flap and in the foveal-sparing flap was reduced during the one-year follow-up period. The results were also confirmed by the anatomical improvement. The authors demonstrated a statistical relationship between the duration of symptoms and changes in the microvasculature in the macula in both groups. No significant differences were found between the various forms of the flap method used in PPV.

DNA methylation of selected tumor suppressor genes in endometrial hyperplasia

Ondrej Dvorak, Munachiso Ndukwe, Marcela Slavickova, Jan Laco, Jiri Spacek

Biomed Pap Med Fac Univ Palacky Olomouc Czech Repub. 2024, 168(1):68-73 | DOI: 10.5507/bp.2022.053

This research study was focused on changes in DNA methylation in specific tumor supressor genes in endometrial hyperplasia. The authors performed a retrospective study of endometrial tissue of 164 patients treated in their department from 2007 to 2014 dividing them into three subsets: atypical hyperplasia, hyperplasia without atypia and a control group with normal endometrial tissue. 25 selected genes using the methylation-specific multiplex ligation-dependent probe amplification (MS-MLPA) probe set were tested. Differences in DNA methylation among the groups were found in PTEN, CDH13, and MSH6 promoters. These genes appear to be involved in different stages of the development of endometrial hyperplasia.
