Abstract
BACKGROUND AND AIM Severe hemodynamic fluctuations during dental treatment can trigger highly undesirable physical reactions. A study was made to determine whether the administration of propofol and sevoflurane contributes to the stabilization of hemodynamic parameters during dental treatment in pediatric patients versus the use of local anesthesia alone. MATERIALS AND METHODS Forty pediatric patients needing dental treatment were assigned to either general anesthesia with local anesthesia (study group [SG]) or local anesthesia alone (control group [CG]). Two percent sevoflurane in oxygen (100% oxygen, 5 L/min) and continuous propofol infusion (target-controlled infusion [TCI], 2 μg/mL) were used as general anesthesia agents in SG; and 2% lidocaine with 1:80,000 adrenaline was used as local anesthesia in both groups. Heart rate, blood pressure and oxygen saturation were measured before starting dental treatment (baseline) and every 10 min during dental treatment. RESULTS Blood pressure (p < .001), heart rate (p = .021) and oxygen saturation (p = .007) decreased substantially after the administration of general anesthesia. The levels of these parameters subsequently remained low and then recovered at the end of the procedure. On the other hand, the oxygen saturation values remained closer to baseline in SG versus CG. In contrast, the hemodynamic parameters experienced lesser fluctuations in CG than in SG. CONCLUSIONS General anesthesia affords more favorable cardiovascular parameters during the entire dental treatment in comparison to local anesthesia alone (blood pressure and heart rate decrease significantly and oxygen saturation proves more stable and with values closer to baseline), and allows dental treatment to be performed on healthy, lacking cooperative ability children who otherwise could not be treated with local anesthesia alone. No side effects were observed in either group.

Abstract
OBJECTIVES To determine whether intravenous (IV) sedation would contribute to the stabilization of patients' hemodynamics during periodontal and oral surgical procedures, and to evaluate the patient-reported outcome measures (PROMs). MATERIALS AND METHODS Periodontal or oral surgery patients were recruited and distributed into two groups: (1) sedation group (SG): intravenous sedation plus local anesthesia; (2) control group (CG): local anesthesia only. Systolic and diastolic blood pressure (SBP, DBP), heart rate (HR), and oxygen saturation (SaO2), were monitored at 15-min intervals from sitting in the dental chair (baseline) until the end of the treatment. In addition, a subjective assessment of PROMs was obtained through a post-operative questionnaire. RESULTS Forty-nine patients (25 in SG and 24 in CG) were included. The highest SBP and DBP were significantly higher in CG compared to the SG (141.1 ± 18.4 and 133.6 ± 15.1, respectively in SBP; and 85.5 ± 11.0 and 82.9 ± 10.1, respectively in DBP), but no mean significant differences were found between groups (P value of 0.85 and 0.72 for systolic and diastolic BP, respectively). HR and SaO2 did not show statistical intra- and inter-group differences. The overall patient satisfaction score was significantly higher in the SG group compared to CG. CONCLUSIONS Intravenous moderate sedation seems to contribute to the stabilization of patient's hemodynamics, especially the systolic blood pressure, although small differences have been found. CLINICAL RELEVANCE Intravenous sedation seems to contribute to stabilize the hemodynamic values, and enhances the patient satisfaction after periodontal and oral surgical treatment in the dental office.

Abstract
BACKGROUND Family process disruption is one of the main consequences of the hospitalization of a critically ill child in a Paediatric Intensive Care Unit (PICU). Children's visits to PICU may help improve family coping. However, this is not standard practice and nurses' experiences in facilitating children's visits to units where it is encouraged is unknown. AIM To explore nurses' experience related to promoting the visits of siblings to PICU. METHODS An interpretative phenomenological study was carried out through in-depth interviews in two PICUs belonging to third level public hospitals in Madrid. Twelve nurses with more than two years of experience in PICU were interviewed. They were all were working in PICU during the study. Furthermore, a PICU psychologist with an experience of four years was interviewed and this was considered shadowed data. Data analysis followed a thematic discourse analysis. RESULTS Nurses' experience of facilitating children's visits to PICU can be condensed into four themes: emerging demand for visits, progressive preparation, decision-making through common consensus and creating intimate spaces. CONCLUSIONS The experience of nurses in facilitating visits is mainly in response to the demand of families going through prolonged hospitalisation or end-of-life situations. The role of the nurse is one of accompaniment, recognising the major role of parents in the preparation of children and in developing the visit. Nurses feel insecure and lack resources for emotional support and demand action protocols to guide intervention and decision making.

Abstract
OBJECTIVE To analyse compliance with the recommendations on the insertion-maintenance of peripheral venous catheter (PVC) and the incidence of complications according to the healthcare department that inserted the PVCs. PATIENTS AND METHODS We conducted a prospective cohort follow-up study of PVCs, from their insertion in the emergency or internal medicine (IM) department until their withdrawal. RESULTS We monitored 590 PVCs, 274 from the emergency department and 316 from IM. In terms of compliance with the process indicators, there was a cannulation rate in the antecubital fossa of 3.5 and 1.6 per 100 catheters-day (P<.001) in the emergency and IM departments, respectively. The sterile placement rates were 1.6 and 12.4 (P<.001), and the rate for transparent dressing was 2.1 and 11.5 (P<.001) per 100 catheters-day in the emergency and IM departments, respectively. The complications rates showed no differences between the departments. The most common complication was phlebitis (95 cases, 16.1%). CONCLUSIONS Compliance with the insertion-maintenance recommendations for PVC showed differences between the departments; however, the incidence of complications was similar.

Abstract
Background The aim of the present review was evaluate the utility and validity of the Bispectral Index (BIS) in dental treatment carried out under endovenous sedation, and compare its efficacy with clinical sedation scales.
Material and Methods Electronic and manual literature searches were conducted by two independent reviewers for articles published up to April 2017 in several databases, including Medline and Cochrane Library.
Results Sixteen articles met the inclusion criteria. A correlation was identified between BIS and clinical sedation scales. A BIS range between 75 and 84 showed a high probability of corresponding to an Observer’s Assessment of Alertness and Sedation Scale (OAA/S) value of 3; a scored 3 on the Ramsay scale corresponds around 85 on the BIS; while BIS values between 57 and 64 corresponded to a University of Michigan Sedation Scale value of 3. BIS monitoring provides continuous measurement of the patient’s hypnotic state or state of consciousness, awareness, and recall. It proved impossible to perform an analysis of statistical data drawn from the studies reviewed due to the disparity of inclusion criteria among the works.
Conclusions BIS for sedation monitoring might make possible to evaluate sedation levels objectively in real time, reducing the dose of the sedative required, increasing safety, and minimizing secondary effects. Key words:Bispectral analysis, BIS monitoring, intravenous sedation, dental treatment, anesthetics.

Abstract
BACKGROUND Residential child care is a very complex measure and has been the subject of heated debate in many countries. However, there is a paucity of studies that examine quality assessments of these services, much less that have asked the children and young people receiving those services about their own evaluations. METHOD This study interviewed 209 young people between 11 and 20 years of age, in 21 residential facilities, about their degree of satisfaction with the care they receive. These residential facilities are differentiated into three types of programs that will be compared: preparation for adult life (PAL), therapeutic care for behavioral problems (TRC) and general programs for children and young people without any specific profile (GRC). The instrument used is an interview that includes both quantitative and qualitative assessments. RESULTS The results show a trend toward positive average scores on practically all aspects, highlighting the support from as well as the connection they feel with the educators who care for them. On the other hand, young people in TRC displayed lower scores on almost all aspects evaluated while those in PAL were the most positive. CONCLUSIONS The main implications for the practice will be discussed from these youths’ perspective.

Abstract
Given the large numbers of sunbathers on beaches, sunscreen compounds are being released into the coastal aquatic environment in significant amounts. Until now the effect of these potential pollutants on microbiota has been not well-known. Phytoplankton is a key component of the microbiota community. It forms the basis of the aquatic trophic networks, and any change in the natural population of phytoplankton can affect the structure of aquatic biota. This paper describes an experiment performed outdoors (in natural sunlight conditions including ultraviolet radiation (UVR) and with UVR blocked) on mixed microalgae populations (four species from different key marine taxonomic groups, Nannochloropsis gaditana, Chaetoceros gracilis, Pleurochrysis roscoffensis and Amphidinium carterae), for three days, exposed to a range of concentrations of three commercial sunscreens (with variable TiO2 concentrations: highest concentration for sunscreen C, followed by sunscreen A; and sunscreen B did not contain TiO2 in its composition). With regard to UVR effect, in the absence of sunscreens, the most sensitive species is the centric diatom, Chaetoceros gracilis, and the least is Nannochloropsis gaditana; this last species presented the same behavior in the absence of UVR and with high sunscreen concentrations. The toxicity gradient obtained for sunscreens and nanoparticles under UVR is: TiO2 NPs>Sunscreen C>Sunscreen A>Sunscreen B. The differential sensitivity of microalgae to sunscreens and TiO2 NPs can produce a change in the dynamics of phytoplankton populations and provoke undesirable ecological effects (such as giving dinoflagellates more prominence). The effects of UVR, commonly neglected in bioassays, could alter the results in important ways and should be considered when performing environmentally-relevant bioassays. The toxicity mediated by hydrogen peroxide production associated with the concentration of TiO2 NPs cannot be considered the only factor responsible for the toxicity: the organic compounds in the sunscreens must also be taken into account.

Abstract
OBJECTIVES A study is made of the dental implications of oral cancer, with a view to avoiding the complications that appear once oncological treatment is started. PATIENTS AND METHODS The study comprised a total of 22 patients diagnosed with oral cancer according to clinical and histological criteria in the Service of Maxillofacial Surgery (Dental Clinic of the University of Barcelona, Spain) during the period 1996-2005, and posteriorly treated in different hospital centers in Barcelona. RESULTS Of the 22 patients diagnosed with oral cancer in our Service, the present study finally analyzed the 12 subjects who reported for the dental controls. As regards the remaining 10 patients, 5 had died and 5 could not be located; these subjects were thus excluded from the analysis. All of the smokers had abandoned the habit. The most common tumor location was the lateral margin of the tongue. None of the patients visited the dentist regularly before the diagnosis of oral cancer. T1N0M0 was the most common tumor stage. Surgery was carried out in 50% of the cases, while 8.4% of the patients received radiotherapy and 41.6% underwent surgery with postoperative radiotherapy. In turn, 66.6% of the patients reported treatment sequelae such as dysgeusia, xerostomia or speech difficulties, and one patient suffered osteoradionecrosis. Forty-one percent of the patients did not undergo regular dental controls after cancer treatment. As regards oral and dental health, 16.6% presented caries, and 50% had active periodontal disease. CONCLUSIONS Protocols are available for preventing the complications of oral cancer treatment, and thus for improving patient quality of life. However, important shortcomings in the application of such protocols on the part of the public health authorities make it difficult to reach these objectives.

Abstract
OBJECTIVE An analysis is made of the incidence of complications following third molar surgical extraction in patients between 12 and 18 years of age. PATIENTS AND METHOD A retrospective study was conducted of 390 surgical extractions of upper and lower third molars in 173 patients operated upon under locoregional anesthesia during the year 2000 in the Master in Oral Surgery and Implantology of Barcelona University Dental School (Spain). The patients were divided into three age groups (A: 12-14 years, B: 15-16 years, C: 17-18 years). The reason for extraction, the degree of dental development, and third molar position, angle and impaction were recorded. Finally, the association of these variables to the appearance of postoperative complications was analyzed. RESULTS Most patients were females (66.9%), and the age group in which most extractions were carried out (62.8%) corresponded to Group C (17-18 years). The main reason for extraction was orthodontist indication (40.5%), closely followed by prophylaxis (39.5%). The existence of clinical manifestations was an indication for extraction in 20% of cases. The postoperative complications rate after the extraction of the global 390 molars was 15.6%. In Groups A, B and C the complication risks were 17.4%, 19% and 13.7%, respectively. All complications were reversible and of short duration. One case each of inferior alveolar nerve paresthesia and lingual nerve paresthesia was recorded, which subsided after one and two months, respectively. CONCLUSIONS There were no significant differences in complications between the three age groups. An increased tendency towards complications was observed in females, and the percentage of postoperative problems increased.

Abstract
Controlled release systems (CRS), unlike the conventional formulations, facilitate a gradual and controlled discharge of the pesticides, reducing the losses by evaporation and leaching and minimizing pesticide pollution. In this study, carbofuran-an insecticide-nematicide identified as a groundwater pollutant-was incorporated in alginate-based granules to obtain controlled release properties. The effect on carbofuran release rate caused by the incorporation of bentonite, activated carbon, and different mixtures of both sorbents in alginate basic formulation was studied by immersion of the granules in water. The water uptake, sorption capacity of the sorbent, permeability, and time taken for 50% of the active ingredient to be released into water, T(50), were calculated by the comparison of the preparations. T(50) values were higher for those formulations containing bentonite and/or activated carbon (T(50) values range from 14.76 h for the alginate formulation containing only bentonite as the sorbent to 29.5 weeks for the alginate formulation containing only activated carbon as the sorbent) than for the preparation without these sorbents (11.72 h). On the basis of a parameter of an empirical equation used to fit the insecticide-nematicide release data, it appears that the release of carbofuran from the various formulations into water is controlled by a diffusion mechanism. The sorption capacity of the sorbents for carbofuran was the most important factor modulating carbofuran release. In addition, it was observed that there is a linear correlation of the T(50) values and the content of activated carbon in dry granules.

Abstract
AIM A study is made to show that most pediatric oral surgical interventions can be performed on a day case surgery or ambulatory basis, and to describe the activity of the Master of Oral Surgery and Implantology (Barcelona University Dental School, Spain) in the year 2000. DESIGN The study documents the surgical activity of the Units of Oral Surgery and Laser Surgery in pediatric patients, in the context of the Master of Oral Surgery and Implantology (Barcelona University Dental School, Spain). RESULTS Of the 3187 operations carried out in our Service in this period, 489 involved patients under 18 years of age. The surgical removal of third molars was the most common intervention (55.6%), followed by other surgical or non-surgical tooth extractions (33.6%) and other interventions (10.6%) comprising fenestration of impacted canines or other teeth, frenectomies, the removal of mucoceles, and tooth relocations. Complications after surgical third molar extraction were recorded in 15.93% of cases, the most frequent problem being the pain and swelling (4.35% each) characteristic of postoperative inflammation. CONCLUSIONS Our experience shows that day case oral surgery can be safely performed in pediatric patients, provided the required means and health care personnel resources are available.

Abstract
A number of processes generically referred to as benign fibroosseous lesions comprise different disorders such as fibrous dysplasia, sclerotizing osteomyelitis and ossifying or cementing fibroma. These processes are all characterized by the existence of a vascular fibroblastic stroma, with the production of a calcified matrix ranging from bone to cementum. Ossifying fibroma involves slow-evolving growth with deforming swelling generally arising in the mandible, with possible early dental displacement. From the radiological perspective the disorder generally manifests as a well defined and delimited, unilocular radiotransparency, as a radiotransparent image with central opacifications, or as multilocular transparencies. The lesions exceptionally can be radiopaque. We present the case of a 22-year-old male presenting for evaluation of a three-month, asymptomatic tumor mass in the anterior sector of the upper jaw. Radiologically, the lesion appeared as a radiotransparent zone surrounded by a poorly delimited sclerotic halo. The definitive diagnosis following surgical resection of the lesion was ossifying fibroma. The case is discussed, and a review is provided of the literature on the subject.
