Introduction: We present a retrospective two-center study series and discussion of the current literature to assess the benefits of facial nerve monitoring during parotidectomy. Materials and Methods: From 2007 to 2012, 128 parotidectomies were performed in 125 patients. Of these, 47 procedures were performed without facial nerve monitoring (group 1) and 81 with facial nerve monitoring (group 2...
The aim of this study was evaluate the behavioral responses of rainbow trout (Oncorhynchus mykiss) exposed to changes in temperature and ammonia. For this purpose were placed separately 8 rainbow trout (average weight of 6±2g, length 5±2 cm) in the treatment and control groups with four replicates in five-liter tanks (cross-sections 7 cm, height 4 cm) Each the tanks have a water inlet and outle...
Geographical extent, increasing intensity and the trend of adding new areas are the challenges of researchers and managers in the face of subsidence crisis due to the withdrawal of groundwater resources in Iran. To these challenges must be added secondary crises such as social, security, food and health consequences. In this regard, the importance of continuous and accurate monitoring in the ...
Twenty four hour oesophageal intraluminal pH probe studies were performed in 114 children (range age: one month-12 years) referred for symptoms or signs compatible with gastroesophageal reflux. Forty five patients had reflux disease alone, 69 had evidence of oesophagitis which was assessed endoscopically and histologically. Recordings were also performed in 63 control patients.

Sediment trapping as a tool to monitor microplastic influx was tested in an urban boreal lake basin. The one-year-long trap monitoring consisted of 5-month and 7-month periods representing growing season winter (including the spring flood event), respectively. accumulation rate (SAR), organic content were determined, highest SAR – 14.5 g/m2/d measured during period. Microplastics extracted from...
BACKGROUND The aim of the study was to evaluate the efficacy and safety of small surface steroid-eluting atrial and ventricular pacing leads in comparison to non-steroid leads using remote monitoring system (Biotronik Home Monitoring®). METHODS In this randomized multicenter prospective trial, SIELLO T steroid-eluting ventricular leads (n = 42) were compared to BPPU T non-steroid leads (n = 4...
BACKGROUND In haematology/oncology units, the frequent and heavy use of broad-spectrum antimicrobials can lead to outbreaks of antimicrobial resistance. Increasing antimicrobial heterogeneity might be a useful strategy for preventing such resistance. METHODS A real-time antimicrobial use density (AUD) monitoring system (RAMS) was developed to precisely assess antimicrobial heterogeneity. This...
