Despite all improvements in transplant medicine, renal transplant recipients have a high risk for cardiovascular mortality. A high prevalence of cardiovascular complications in renal transplant recipients (RTR) is explained by cardiovascular risk factors present before transplantation, in addition to the development of new risk factors as well as worsening of preexisting risk factors after transplantation. A majority ot these patients develop metabolic syndrome within a year after the transplantation. The metabolic syndrome (MS) is associated with impaired renal allograft function and increased insulin resistance. Non alcoholic fatty liver disease (NAFLD) represents a liver manifestation of metabolic syndrome and it development is strongly associated with all components of MS in general population. The current importance of NAFLD and its link to the MS has encouraged an interest in its possible role in the development of atherosclerosis in recent years. Considering the fact that all components of MS are more common among renal transplant recipients compared to general population, it would be expected that RTR may have a much higher incidence of NAFLD compared to general population. We propose that the presence of NAFLD in RTR could be a strong predictor in cardiovascular morbidity and mortality. Also, according to the recent investigations about the possible link between NAFLD and chronic kidney disease, we hypothesis that NAFLD may be associated with deteriorating graft function, causing a chronic allograft nephropathy and graft loss. Common factors underlying the pathogenesis of NAFLD and chronic allograft dysfunction may be insulin resistance, oxidative stress, activation of rennin-angiotensin system, and inappropriate secretion of inflammatory cytokines by steatotic and inflamed liver. © 2013 Elsevier Ltd.

BACKGROUND: There are limited data available on interferon-γ release assay (IGRA) performance in children up to 5 years of age, with documented exposure to active tuberculosis (TB). The aim of this study was to evaluate (1) the influence of infectivity of adult source cases on test results, (2) the impact of age, and (3) the level of agreement, between IGRA and tuberculin skin test (TST) results. METHODS: A total of 142 Bacille Calmette-Guerin-vaccinated children up to 5 years of age were investigated because of a history of exposure to active TB. QuantiFERON-TB Gold In-Tube IGRA (QFT) and TST assays were performed. RESULTS: Test results were significantly influenced by positive finding of cavitary lesions (QFT, odds ratio [OR] = 6.15; TST, OR = 7.48) and positive acid-fast bacilli (QFT, OR = 4.01; TST, OR = 4.47) in active TB contacts. QFT resulted in 1 indeterminate response (0.7%), attributable to low mitogen. There was no evidence for age having any effect on QFT performance. The 2 tests showed a moderate overall concordance (89%; κ = 0.591) at a TST cutoff value of ≥10 mm. CONCLUSIONS: Association of positive QFT and TST results with risk factors for infection in child contacts (presence of cavitary lesions and acid-fast bacilli smear positivity in index cases) suggests that both the tests have good diagnostic accuracy. However, there was significant discord between results of the 2 tests that could not be definitively resolved. Thus, in a high-risk population of children up to 5 years of age, both tests (QFT and TST) should be performed and the child should be considered infected if either or both tests are positive.

Non-alcoholic fatty liver disease (NAFLD) is the most common liver disease in Western countries. Today it is believed that NAFLD is a hepatic manifestation of metabolic syndrome, and thus it is closely related to the cardiovascular morbidity and mortality. Cardiovascular diseases (CVD) are the leading cause of morbidity and mortality in patients with end-stage-renal disease (ESRD). NAFLD and ESRD share some important cardiometabolic risk factors and possible common pathophyisiological mechanisms, and are linked to an increased risk of incident CVD events. We hypothesize that the coexistence of these two conditions could lead to much faster progress of the aterogenic process. Furthermore, patients with ESRD who suffer from NAFLD have a much higher risk for the development of adverse CVD events. Given the high prevalence of NAFLD, and its tight association with other manifestations of the metabolic syndrome and thus cardiovascular complications, it is important to recognize and aggressively treat this condition in ESRD patients. To evaluate this hypothesis, we propose the use of non-invasive methods such as transient elastography (TE) (Fibroscan-CAP) for the detection and quantification of liver steatosis and fibrosis, as well as an abdominal ultrasound for detecting liver steatosis. We focus on their correlation with carotid intima-media thickness (IMT) and plaque as surrogate measures of increased cardiovascular risk in HD patients in order to investigate the association of NAFLD and increase risk of adverse CVD events. This evaluation will prove useful in assessing the risk in HD patients with NAFLD for increase CVD mortality. © 2013 Elsevier Ltd.

To determine the occurence of embolism in retinal circulation after invasive cardiovascular procedures and the risk of central retinal artery occlusion (CRAO) and branch retinal artery occlusion (BRAO). During a 3 month period 153 patients (303 eyes)--101 male/52 female--who had undergone coronarography or stent implantation were examined before and 24 hours after the procedure. Best corrected visual acuity (BCVA) was taken, visual field examination was done and fundoscopy was performed. Eyes with the opacities in the anterior segment (corneal leucoma, dense cataracts) were excluded from the study. Prior to invasive procedure none of the patients had embolism in the retinal circulation. Embolism was found in 3 patients (male) who all had hyperlipidemia with normal blood pressure. Two of them had coronarography and one patient had stent implantation. One of the patients had a previous branch retinal vein occlusion (BRVO) that was treated with photocoagulation. They did not report any symptoms. BCVA was the same before and after the procedure. Two of the emboli were located in the first branch of the central retinal artery and one was located in the branch of cillioretinal artery. All of the emboli were transient after 48 hours. The study showed that invasive cardiovascular procedures do have the risk of developing transient embolism in retinal circulation. However, there have been reports of CRAO and BRAO after diagnostic cardiac procedures, therefore clinicians should be aware of this potential complication.

In 10-15% of the patients that underwent cholecystectomy, common bile duct stones were found either during the preoperative, intraoperative or postoperative evaluation. Their treatment traditionally was based on open approach and extraction of calculi, with development of endoscopic procedures we have ERCP with endoscopic sphincterotomy, but due to rapid development of laparoscopic procedures now-days we have other therapeutic options such as laparoscopic transcystic extraction and laparoscopic choledohotomy. METHODS: During the period between 2007-2009 we treated 168 patients with common bile duct stones. Age range was 21-78 years, 105 female and 63 male patients. We have performed 47 open explorations, 9 laparoscopic transcystic exploration, as well as 112 ERCP and ES. We monitored the rate of success (%), intra- and postoperative complications. RESULTS: The success rate of the cases of open exploration was 95%, in 2 cases postoperative cholangiogram showed concrement residues that were successfully treated later on with ERCP+ES. Out of 9 transcystic LCBDE we have performed, in 4 cases extraction was successful, 3 patients underwent conversion into open exploration, and 2 patients were successfully treated with postoperative ERCP. A total of 69 patients were treated with ERCP and ES with the 82% success rate of stone extraction. CONCLUSION: Even though laparoscopic and endoscopic procedures have revolutionized treatment of common bile duct stones, the role of ERCP is not changed. Treatment in general hospital settings largely depends on availability of endoscopic and laparoscopic equipment and expertise, and must be individualized according to methods that are available. In our settings we have found that best summary of these demands are achieved by ERCP and laparoscopic approach.

Background: Lyme borreliosis is the most prevalent tick-borne disease in Europe. Ixodes ricinus also carries other pathogenic bacteria, but corresponding human diseases are rarely reported. Here, we compared the exposure to Rickettsia helvetica and Rickettsia monacensis with that to Lyme borreliosis spirochetes. We assumed that their exposure corresponds to their infection rate in questing I. ricinus. Findings. Three Rickettsia species were detected in ticks with a total prevalence of 7.9%, of which the majority was R. helvetica (78%) and R. monacensis (21%). From the same geographic area, skin biopsies of erythema migrans patients were investigated for possible co-infections with Rickettsia spp. Forty-seven out of 67 skin biopsies were PCR positive for Borrelia burgdorferi s.l. and one sample was positive for R. monacensis. The Borrelia genospecies from the R. monacensis positive patient was identified as Borrelia afzelii. The patient did not show any symptoms associated with rickettsiosis. Conclusions: Co-infections of I. ricinus with Rickettsia spp. and B. burgdorferi s.l. were as high as expected from the individual prevalence of both pathogens. Co-infection rate in erythema migrans patients corresponded well with tick infection rates. To our knowledge, this is the first reported co-infection of B. afzelii and R. monacensis. © 2013 Tijsse-Klasen et al.; licensee BioMed Central Ltd.

Since an originally anti-ulcer stable gastric pentadecapeptide BPC 157 (PL 14736) was shown to promote healing of injured striated muscle and smooth muscle in the gastrointestinal tract, we explored its therapeutic potentials for leak point pressure (LPP) recovery in rat stress urinary incontinence (SUI) after transabdominal urethrolysis (TU) and prolonged vaginal dilatation (VD). During a 7-day period, TU-rats and VD-rats (or healthy rats) received BPC 157, either (i) intraperitoneally, 10 μg/kg or 10 ng/kg, once daily (first administration 30 min after surgery, last 24 h before LPP-testing and sacrifice), or (ii) per-orally, 10 μg/kg in drinking water (0.16 μg/mL, 12 mL/rat/day). Vesicourethral segments were harvested for immunohistochemical evaluation. All BPC 157 regimens counteracted decrease of LPP values in TU-rats and VD-rats. Additionally, BPC 157-TU rats (μg-intraperitoneally or per-orally) and BPC 157-VD rats (μg intraperitoneally) reached LPP values originally noted in healthy rats. Conversely, in healthy rats, BPC 157 did not alter LPP. Immunohistochemical studies revealed higher desmin (delineates striated organization of skeletal muscle), smooth muscle actin, and CD34 (angiogenic marker) positivity within the urethral wall in BPC 157-treated rats vs. controls, as well as overall preserved muscle/connective tissue ratio assessed with Mallory's trichrome staining. Pentadecapeptide BPC 157, applied parenterally or per-orally, appears to ameliorate the SUI in rat models, improving the otherwise detrimental course of healing after VD and TU, which may be analogous to human injury. These beneficial effects may possibly be selectively used in future strategies for treatment of SUI.

Endemic (Balkan) nephropathy is a chronic tubulointerstitial disease frequently accompanied by urothelial cell carcinomas of the upper urinary tract. This disorder has recently been linked to exposure to aristolochic acid, a powerful nephrotoxin and human carcinogen. Following metabolic activation, aristolochic acid reacts with genomic DNA to form aristolactam-DNA adducts that generate a unique TP53 mutational spectrum in the urothelium. The aristolactam-DNA adducts are concentrated in the renal cortex, thus serving as biomarkers of internal exposure to aristolochic acid. Here, we present molecular epidemiologic evidence relating carcinomas of the upper urinary tract to dietary exposure to aristolochic acid. DNA was extracted from the renal cortex and urothelial tumor tissue of 67 patients that underwent nephroureterectomy for carcinomas of the upper urinary tract and resided in regions of known endemic nephropathy. Ten patients from nonendemic regions with carcinomas of the upper urinary tract served as controls. Aristolactam-DNA adducts were quantified by 32P-postlabeling, the adduct was confirmed by mass spectrometry, and TP53 mutations in tumor tissues were identified by chip sequencing. Adducts were present in 70% of the endemic cohort and in 94% of patients with specific A:T to T:A mutations in TP53. In contrast, neither aristolactam-DNA adducts nor specific mutations were detected in tissues of patients residing in nonendemic regions. Thus, in genetically susceptible individuals, dietary exposure to aristolochic acid is causally related to endemic nephropathy and carcinomas of the upper urinary tract. © 2012 International Society of Nephrology.

Objective: To analyze how different thermal processing methods affect the protein, calcium, and phosphorus content of hospital food served to dialysis patients and to generate recommendations for preparing menus that optimize nutritional content while minimizing the risk of hyperphosphatemia. Design and Methods: Standard Official Methods of Analysis (AOAC) methods were used to determine dry matter, protein, calcium, and phosphorus content in potatoes, fresh and frozen carrots, frozen green beans, chicken, beef and pork, frozen hake, pasta, and rice. These levels were determined both before and after boiling in water, steaming, stewing in oil or water, or roasting. Results: Most of the thermal processing methods did not significantly reduce protein content. Boiling increased calcium content in all foodstuffs because of calcium absorption from the hard water. In contrast, stewing in oil containing a small amount of water decreased the calcium content of vegetables by 8% to 35% and of chicken meat by 12% to 40% on a dry weight basis. Some types of thermal processing significantly reduced the phosphorus content of the various foodstuffs, with levels decreasing by 27% to 43% for fresh and frozen vegetables, 10% to 49% for meat, 7% for pasta, and 22.8% for rice on a dry weight basis. On the basis of these results, we modified the thermal processing methods used to prepare a standard hospital menu for dialysis patients. Foodstuffs prepared according to the optimized menu were similar in protein content, higher in calcium, and significantly lower in phosphorus than foodstuffs prepared according to the standard menu. Conclusions: Boiling in water and stewing in oil containing some water significantly reduced phosphorus content without affecting protein content. Soaking meat in cold water for 1h before thermal processing reduced phosphorus content even more. These results may help optimize the design of menus for dialysis patients. © 2015 National Kidney Foundation, Inc.

Article presents a laparoscopic cystogastrostomy of pancreatic pseudocysts. Pancreatic pseudocyst is a common complication of acute or chronic pancreatitis. It is treated by drainage. Until the development of laparoscopic method, the only surgical type of treatment was a drainage of pseudocyst into the stomach or intestine by the open surgery. In a recent years, a new procedures of laparoscopic treating of pseudocysts pancreatic were published. Despite of the small number of cases it is legible that this certain method of operative treatment has clear benefits for the patient. Herewith, we present a laparoscopic transgastric cystogastrostomy of the 44-year old woman who was admitted because of acute biliary pancreatitis. She was operated six months after the acute attack.
