Backround. Children's developing teeth may be sensitive to environmental pollutants such as polychlorinated dibenzo- p -dioxins (PCDDs) and polychlorinated dibenzofurans. The term molar incisor hypomineralization (MIH) was introduced to describe the clinical appearance of enamel hypomineralization of systemic origin affecting one or more permanent first molars (PFMs) that are associated frequently with affected incisors.
Aim. The aim of this study was to determine the prevalance of MIH in children from the most industrialized and polluted region and the most green-energy island of Turkey.
Design. In September 2007, a retrospective study was initiated in two elementary schools: one, a group of children ( N = 153) who fitted the criteria from Tavsancil, Kocaeli ( N = 109) and the other from Bozcaada island, Canakkale ( N = 44). The soil samples were collected from selected regions in order to determine the contamination levels in a heavily industrialized area and a non-industrialized area.
Results. Prevalance of MIH in children in Bozcaada island was 9.1%, while prevalance of MIH was 9.2% in Tavsancil. The PCDD/F levels in soil samples collected from Bozcaada and Tavsancil were determined as 1,12 and 8,4 I-TEQ ng/kg dry soil, respectively ( P < 0.001).
Conclusions. In this preliminary study with a small study population, prevalence of MIH did not seem to be associated with the levels of PCDD/Fs in the environment. 相似文献

OBJECTIVE: To determine the efficacy of shock wave lithotripsy (SWL) in anomalous kidneys. METHODS: From October 1990 to October 2002, 150 patients (93 men and 57 women) with anomalous urinary tracts, including 45 horseshoe kidneys, 57 duplex kidneys, 30 malrotated kidneys, 14 pelvic and four crossed ectopic kidneys were treated with SWL for urolithiasis at the Gazi University Faculty of Medicine. Shock wave lithotripsy was performed with Siemens Lithostar plus (Siemans, Erlanger, Germany) device and all procedures were carried under fluoroscopic control. Results: The mean shock wave number and intensity received by the patients was 3770 (range, 1380-4100) shocks and 18.4 (range, 16.1-19) kV per session, respectively. The minimum success rate was obtained in patients with lower calyceal (50%) followed by middle calyceal (60%) calculi. The stone-free rate decreased and the number of sessions per patient increased with increasing stone diameter (dm). In patients with a stone dm > 30 mm, only 34% could be stone-free, compared to a rate of 92% for calculi dm < 10 mm. The overall stone free rate at the third month was 68%. The best stone-free rates were obtained in patients with ureteral duplication (80.7%). The stone-free rates in horseshoe, malrotated, pelvic and crossed ectopic kidneys were found to be 66.7%, 56.7%, 57.2% and 25%, respectively. CONCLUSION: Shock wave lithotripsy might be an effective and minimally invasive treatment alternative in stone-bearing anomalous kidneys. The type of anomaly, stone burden and localization seem to be the main parameters effecting the treatment success. 相似文献

Aim: Cardiovascular abnormalities are common in children with chronic kidney disease (CKD). Left ventricular (LV) structure and functions have been extensively studied by conventional pulse-wave Doppler echocardiography (cPWD), however, tissue Doppler imaging (TDI) is a relatively new echocardiography method. The aims of this study were to evaluate LV diastolic function in paediatric dialysis patients using cPWD and TDI methods, and to compare the findings obtained with two modalities.
Methods: This study included 38 children and adolescents on dialysis (14 haemodialysis and 24 peritoneal dialysis, duration of dialysis 58.0 ± 32.8 months) and 16 age- and sex-matched healthy subjects.
Results: The mean left ventricular mass index (LVMI) was significantly higher in the patient group ( P < 0.001) and the most common cardiac geometry was concentric LV hypertrophy (55%). There was no significant difference in LV systolic function between patient and control groups. However, dialysis patients had worse LV diastolic function both according to cPWD (lower E/A ratio) and TDI (lower Em/Am ratio) than the healthy subjects ( P < 0.001 and P = 0.001, respectively). Also, the index of LV filling pressure (E/Em ratio) obtained by the combination of cPWD and TDI was significantly higher in the patients ( P < 0.001). Cumulative dose of calcium-based phosphate binder (CBPB), diastolic blood pressure and LVMI were the independent predictors of E/Em ratio.
Conclusion: Our study shows that LV diastolic dysfunction is common in paediatric dialysis patients and TDI findings correlate well with cPWD findings. Similarly, higher dose intake of CBPB, hypertension and LV hypertrophy have a negative effect on LV filling pressure suggesting diastolic function. 相似文献

Transition zone biopsy and prediction of extraprostatic extension at radical prostatectomy 总被引:1,自引:0,他引:1

BACKGROUND: There is limited data in the literature that suggests that transition zone (TZ) biopsy might be useful for the prediction of extraprostatic extension (EPE) in clinically localized prostate cancer. We studied the role of TZ biopsy in the prediction of EPE. METHODS: Transition zone biopsies were performed in addition to systematic peripheral zone (PZ) biopsies between November 1995 and December 1999. During this period, 59 patients underwent radical prostatectomy for clinically localized disease. Final pathological results were compared with preoperative clinical and biopsy findings. RESULTS: Of the 59 patients who underwent radical prostatectomy, 46 had cancer only in the PZ cores and 13 had cancer both in the PZ and the TZ cores at the biopsy. Final histopathological results revealed EPE in 19 (32%) patients and positive surgical margins in 22 (37%). In univariate analysis of age, prostate-specific antigen (PSA), mean percentage of positive PZ cores, mean biopsy Gleason score and positive TZ biopsy, there was a significant difference for serum PSA levels (P = 0.021), presence of positive TZ cores (P = 0.018) and percentage of positive PZ cores in patients with and without EPE (P < 0.001). In multivariate analysis, the single independent predictor of EPE was the percentage of positive PZ biopsy cores (P = 0.0227). There was agreement between the side of positive TZ biopsy and EPE in seven of eight patients. CONCLUSION: Taking two TZ cores in addition to peripheral sextant biopsy did not result in better prediction of EPE. The relationship between TZ involvement and the presence of EPE can be investigated further in radical prostatectomy specimens. 相似文献

BACKGROUND: Hypomagnesaemia and hyperleptinemia are common in patients with diabetes. Moreover, it has been demonstrated that leptin stimulates diuresis and natriuresis. The aim of this study was to evaluate the relationship between serum leptin, serum magnesium (Mg) and urinary Mg/urinary creatinine levels in patients with type 1 diabetes. METHODS: Serum leptin and Mg and urinary Mg/urinary creatinine levels were measured in 67 patients with diabetes (33 girls and 34 boys). The age, diabetes duration, anthropometric and metabolic parameters of the subjects were matched between girls and boys. The relation of serum leptin levels to serum and urinary Mg/urinary creatinine levels was assessed. RESULTS: Serum leptin levels of girls with diabetes were higher than those of the boys (14 +/- 5.3 microg/L vs 5.8 +/- 1.5 microg/L, P < 0.001, respectively). The differences for serum Mg and for urinary Mg/urinary creatinine levels were not significant between girls and boys with diabetes. Leptin levels were correlated with urinary Mg/urinary creatinine levels in both girls and boys (r = 0.39, P = 0.02 and r = 0.37, P = 0.03, respectively). In a multivariate regression model, leptin emerged as independent correlates for mean urinary Mg/urinary creatinine in both girls and boys with the total variance explained being 14%, and 15%, respectively. CONCLUSION: The data suggest that serum leptin might be related to increased urinary Mg loss in patients with type I diabetes. 相似文献
