- Effect of Intraperitoneal Curcumin Instillation on Postoperative Peritoneal Adhesions. [JOURNAL ARTICLE]
- Med Princ Pract 2014 Dec 10.
Objective: The aim of this study was to determine the effect of curcumin on adhesion formation in a rat cecum abrasion model. Materials and Methods: Thirty Wistar rats were randomized into three groups; the control group received saline, the curcumin group received 10 mg/kg of curcumin after cecal abrasion, and in the sham group the abdominal wall was closed without any abrasion to the cecum. On day 15, adhesions were assessed blindly using a standardized scale, and histopathological samples were taken and examined. Results: There were no incisional hernias or wound dehiscences in any animals of the three groups. A comparison of adhesion scores showed a significant difference between the curcumin (median = 1) and the control group (median = 2; p < 0.05). The grade of inflammation of the curcumin (median = 1) and the sham (median = 0) group was significantly lower than that of the control group (median = 3; p < 0.01 and p < 0.001, respectively). Hydroxyproline levels were significantly lower in the sham (48.3 ± 11.8 µg/mg) and the curcumin (63.8 ± 13.9 µg/mg) group compared to the control group (85.7 ± 22.1 µg/mg; p < 0.05). Conclusion: These data suggest that curcumin, administered intraperitoneally, was effective in the prevention of peritoneal adhesion formation. © 2014 S. Karger AG, Basel.

- Sepsis in Poland: Why Do We Die? [JOURNAL ARTICLE]
- Med Princ Pract 2014 Dec 10.
Objective: To investigate the adverse events and potential risk factors in patients who develop sepsis. Subjects and Methods: Fifty-five medico-legal opinion forms relating to sepsis cases issued by the Department of Forensic Medicine, Wroclaw, Poland, between 2004 and 2013 were analyzed for medical errors and risk factors for adverse events. Results: The most common causes of medical errors were a lack of knowledge in recognition, diagnosis and therapy as well as ignorance of risk. The common risk factors for adverse events were deferral of a diagnostic or therapeutic decision, high-level anxiety of patients or their families about the patient's health and actively seeking for help. The most significant risk factors were communication errors, not enough medical staff, stereotype-based thinking about diseases and providing easy explanations for serious symptoms. Conclusion: The most common cause of adverse events related to sepsis in the Polish health-care system was a lack of knowledge about the symptoms, diagnosis and treatment as well as the ignoring of danger. A possible means of improving safety might be through spreading knowledge and creating medical management algorithms for all health-care workers, especially physicians. © 2014 S. Karger AG, Basel.
- Tumor Necrosis Factor-α and Pregnancy Complications: A Prospective Study. [JOURNAL ARTICLE]
- Med Princ Pract 2014 Dec 5.
Objective: The aim of this study was to compare the levels of tumor necrosis factor-α (TNF-α) produced by peripheral blood mononuclear cells in normal pregnancies and pregnancies with complications. Materials and Methods: Maternal peripheral blood mononuclear cells from women with a recurrent spontaneous miscarriage (n = 35), premature rupture of fetal membranes (n = 30), preeclampsia (n = 27) and intrauterine fetal growth retardation (IUGR; n = 36) were stimulated with mitogen or antigen, and the levels of TNF-α produced were compared to those produced by peripheral blood mononuclear cells from a normal pregnancy (n = 35). Results: The median levels of mitogen-induced TNF-α at the 1st, 2nd and 3rd trimester, and at normal delivery were 1,176.4, 4,320.9, 7,307.4 and 2,463.0 pg/ml, respectively, while those produced in the recurrent spontaneous miscarriage, premature rupture of membranes and preeclampsia cases were 4,159.8, 3,489.5 and 4,149.2 pg/ml, respectively. The differences were statistically significantly higher in these pregnancy complications (p = 0.04, 0.024 and 0.014) as compared to the levels in normal pregnancy. Furthermore, antigen-induced TNF-α levels were produced at statistically significantly higher levels by women with IUGR (120.4 pg/ml) compared to women with normal pregnancies (17.9 pg/ml; p = 0.041). Conclusion: Higher levels of TNF-α seem to play a role in these pregnancy complications, suggesting its pathogenesis in such conditions. © 2014 S. Karger AG, Basel.
- Diabetic Patients Have Increased Perioperative Cardiac Risk in Heart-Type Fatty Acid-Binding Protein-Based Assessment. [JOURNAL ARTICLE]
- Med Princ Pract 2014 Nov 29.
Objective:To test the potential role of heart-type fatty acid-binding protein (H-FABP) in detecting increased perioperative cardiac risk in comparison with cardiac troponin I (cTnI) in the early postoperative period. Subjects and
Methods:Sixty-seven patients who had clinical risk factors and underwent elective intermediate - or high-risk noncardiac surgery were included in this study. Serum specimens were analyzed for H-FABP and cTnI levels before and at 8 h after surgery. None of the patients had chest pain; 27 had a history of ischemic heart disease, 3 of heart failure, 5 of cerebrovascular diseases, 40 of diabetes and 46 of hypertension.
Results:The mean duration of the operations was 2.33 ± 1.27 h (range 1-6). In the postoperative period, 27 (40.3%) patients had increased H-FABP levels (≥7.5 ng/ml); the median preoperative serum H-FABP level was 0.13 ng/ml (<0.1-5.9) and the median postoperative H-FABP level was 6.86 ng/ml (<0.1-13.7). Only 1 (1.5%) patient had cTnI >0.1 µg/l during the postoperative period. Correlation analysis revealed that the presence of diabetes was associated with an increased H-FABP level (r = 0.30, p = 0.01). Of the 27 patients with H-FABP ≥7.5 ng/ml, 21 (87%) had diabetes. There was no significant correlation with other clinical risk factors, type or duration of surgery.
Conclusion:The H-FABP levels significantly increased in the postoperative period. Most patients with increased postoperative H-FABP levels were diabetic. High H-FABP levels could alert clinicians to increased perioperative cardiovascular risk and could prevent underdiagnosis, especially in diabetic patients. © 2014 S. Karger AG, Basel.

- Amyloid-Beta: A Crucial Factor in Alzheimer's Disease. [JOURNAL ARTICLE]
- Med Princ Pract 2014 Nov 27.
Alzheimer's disease (AD) is the most prevalent form of dementia which affects people older than 60 years of age. In AD, the dysregulation of the amyloid-beta (Aβ) level leads to the appearance of senile plaques which contain Aβ depositions. Aβ is a complex biological molecule which interacts with many types of receptors and/or forms insoluble assemblies and, eventually, its nonphysiological depositions alternate with the normal neuronal conditions. In this situation, AD signs appear and the patients experience marked cognitional disabilities. In general, intellect, social skills, personality, and memory are influenced by this disease and, in the long run, it leads to a reduction in quality of life and life expectancy. Due to the pivotal role of Aβ in the pathobiology of AD, a great deal of effort has been made to reveal its exact role in neuronal dysfunctions and to finding efficacious therapeutic strategies against its adverse neuronal outcomes. Hence, the determination of its different molecular assemblies and the mechanisms underlying its pathological effects are of interest. In the present paper, some of the well-established structural forms of Aβ, its interactions with various receptors and possible molecular and cellular mechanisms underlying its neurotoxicity are discussed. In addition, several Aβ-based rodent models of AD are reviewed. © 2014 S. Karger AG, Basel.
- In vitro Adhesion of Oral Candida dubliniensis Isolates to Acrylic Denture Surfaces following Brief Exposure to Sub-Cidal Concentrations of Polyenes, Azoles and Chlorhexidine. [JOURNAL ARTICLE]
- Med Princ Pract 2014 Nov 29.
Objectives:We aimed to investigate the effect of brief exposure to sub-cidal concentrations of nystatin, amphotericin B, ketoconazole, fluconazole and chlorhexidine gluconate on the adhesion of oral Candida dubliniensis isolates to the surface of acrylic dentures.
Methods:After determining the minimum inhibitory concentration of each drug, 20 oral isolates of C. dubliniensis were exposed to sub-cidal concentrations of the drugs for 1 h. The drugs were then removed by dilution, and the adhesion of the isolates to denture acrylic strips was assessed by an in vitro adhesion assay.
Results:Compared to the controls, exposure to nystatin, amphotericin B, ketoconazole, fluconazole and chlorhexidine gluconate suppressed the ability of C. dubliniensis isolates to adhere to acrylic denture surfaces with a reduction of 74.68, 74.27, 57.31, 44.57 and 56.53% (p < 0.001 for all drugs), respectively.
Conclusions:Brief exposure to sub-cidal concentrations of anti-mycotics suppressed the adhesion of C. dubliniensis oral isolates to acrylic denture surfaces. © 2014 S. Karger AG, Basel.
