RESUMEN

BACKGROUND: The removal of third molars (3Ms) is the most frequent surgical procedure in the field of Oral Surgery. As a result, the Spanish Society of Oral Surgery (SECIB) aims to create a Clinical Practice Guideline (CPG) that offers evidence-based recommendations for optimal clinical practice. Specifically, the CPG will focus on providing guidance regarding the indications and criteria for clinical and radiological diagnosis of patients with 3Ms. MATERIAL AND METHODS: This CPG was developed by the SECIB, following the methodological guidelines described in the methodological manual for the "Development of Clinical Practice Guidelines in the National Health System". Several PICO questions related to the diagnosis and indications for the extraction of 3Ms were formulated. The leading experts carried out the evaluation of the evidence and the formulation of specific recommendations. RESULTS: A total of 17 PICO questions were evaluated, addressing the indications, prognosis, diagnosis, and cost-benefit relationship of 3M extraction. CONCLUSIONS: The present Clinical Practice Guideline provides evidence-based recommendations on the diagnosis and indications for 3M extraction. These evidence-based recommendations can assist healthcare professionals and the general population in making informed decisions regarding the management of 3Ms.

RESUMEN

Surgical site infection (SSI) is a major infectious complication that increases mortality, morbidity, and healthcare costs. There are scores attempting to classify patients for calculating SSI risk. Our objectives were to validate the Australian Clinical Risk Index (ACRI) in a European population after cardiac surgery, comparing it against the National Nosocomial Infections Surveillance-derived risk index (NNIS) and analyzing the predictive power of ACRI for SSI in valvular patients. All the patients that who underwent cardiac surgery in a tertiary university hospital between 2011 and 2015 were analyzed. The patients were divided into valvular and coronary groups, excluding mixed patients. The ACRI score was validated in both groups and its ability to predict SSI was compared to the NNIS risk index. We analyzed 1,657 procedures. In the valvular patient group (n: 1119), a correlation between the ACRI score and SSI development (p < 0.05) was found; there was no such correlation with the NNIS index. The area under the receiver-operating characteristic curve (AUC) was 0.64 (confidence interval [CI] 95%, 0.5-0.7) for ACRI and 0.62 (95% CI, 0.5-0.7) for NNIS. In the coronary group (n: 281), there was a correlation between ACRI and SSI but no between NNIS and SSI. The ACRI AUC was 0.70 (95% CI, 0.5-0.8) and the NNIS AUC was 0.60 (95% CI, 0.4-0.7). The ACRI score has insufficient predictive power, although it predicts SSI development better than the NNIS index, fundamentally in coronary artery bypass grafting (CABG). Further studies analyzing determining factors are needed.

RESUMEN

BACKGROUND: Mexico's 2009 "narcomenudeo reform" decriminalized small amounts of drugs, shifting some drug law enforcement to the states and mandating drug treatment diversion instead of incarceration. Data from Tijuana suggested limited implementation of this harm reduction-oriented policy. We studied whether a police education program (PEP) improved officers' drug and syringe policy knowledge, and aimed to identify participant characteristics associated with improvement of drug policy knowledge. METHODS: Pre- and post-training surveys were self-administered by municipal police officers to measure legal knowledge. Training impact was assessed through matched paired nominal data using McNemar's tests. Multivariable logistic regression was used to identify predictors of improved legal knowledge, as measured by officers' ability to identify conceptual legal provisions related to syringe possession and thresholds of drugs covered under the reform. RESULTS: Of 1750 respondents comparing pre- versus post training, officers reported significant improvement (p < 0.001) in their technical understanding of syringe possession (56 to 91%) and drug amounts decriminalized, including marijuana (9 to 52%), heroin (8 to 71%), and methamphetamine (7 to 70%). The training was associated with even greater success in improving conceptual legal knowledge for syringe possession (67 to 96%) (p < 0.001), marijuana (16 to 91%), heroin (11 to 91%), and methamphetamine (11 to 89%). In multivariable modeling, those with at least a high school education were more likely to exhibit improvement of conceptual legal knowledge of syringe possession (adjusted odds ratio [aOR] 2.6, 95% CI 1.4-3.2) and decriminalization for heroin (aOR 2.7, 95% CI 1.3-4.3), methamphetamine (aOR 2.2, 95% CI 1.4-3.2), and marijuana (aOR 2.5, 95% CI 1.6-4). CONCLUSIONS: Drug policy reform is often necessary, but not sufficient to achieve public health goals because of gaps in translating formal laws to policing practice. To close such gaps, PEP initiatives bundling occupational safety information with relevant legal content demonstrate clear promise. Our findings underscore additional efforts needed to raise technical knowledge of the law among personnel tasked with its enforcement. Police professionalization, including minimum educational standards, appear critical for aligning policing with harm reduction goals.

RESUMEN

Systematic and structured methods must be used to ensure that healthcare risks are effectively managed. Spanish standard UNE 179003:2013 provides healthcare organizations with a framework and a systematic protocol for managing patient safety from a clinical and organizational perspective. Furthermore, it is useful in securing an efficient balance among health risk, health outcomes and costs. The UNE 179003:2013 certifies that a clinical service complies with rules and operating procedures aimed at reducing the incidence of adverse events. It also requires mandatory continuous improvement, given that the standard entails frequent monitoring of the risk management system through periodic audits. The aims of this paper are to describe the UNE 179003:2013 certification process in an Intensive Care Unit, propose a risk management program for critical patients, and offer some recommendations regarding its implementation.

RESUMEN

A syndrome has been recognized on leatherleaf fern (Rumohra adiantiformis) in Costa Rica for many years that causes widespread damage but has not been described in the literature. A full description of the syndrome, termed fern distortion syndrome (FDS), is reported here, along with evidence that FDS is a new disease and that it is associated with endophytic fluorescent pseudomonads but not with any other major groups of pathogens or pests. The main aboveground symptoms of FDS are twisting and distortions of fronds, which make the fronds unmarketable. In advanced cases of FDS, fronds are often thickened, new frond growth ceases or slows dramatically, and uneven sporulation is apparent on the underside of fronds. Symptoms of FDS belowground are reduced diameter of rhizomes and reduced overall root mass. The incidence of FDS in Costa Rica was typically over 80%, and severity typically ranged from 1.26 to 2.48 using a 0 to 3 rating scale in fields propagated vegetatively with rhizomes from fields with FDS. In contrast, in three fields planted 1.5 to 4 years previously with rhizomes derived from tissue culture, incidence and severity were markedly lower: 23 to 34% and 0.24 to 0.36, respectively. Paired sampling of symptomatic and asymptomatic plants revealed significantly greater populations of fluorescent pseudomonads inside rhizomes of symptomatic plants.

RESUMEN

We report two cases of hemoglobin Sendagi in a Romanian family residing in Spain: a four-year-old boy and his mother, who had been previously diagnosed with another type of congenital hemolytic anemia and had undergone splenectomy in her country during childhood. The unstable hemoglobin variant, hemoglobin Sendagi, is characterized by decreased oxygen affinity caused by replacement of one of the critical amino acid residues, phenylalanine beta 42 (CD1) of the beta-chain, with valine in the heme pocket, resulting in methemoglobin formation. As a result of migratory movements in Europe, new disease-causing hemoglobin variants are emerging in our country. Here, capillary electrophoresis enabled the identification of the variant and a molecular study was used to establish an accurate diagnosis.

RESUMEN

The aim of this study was to demonstrate the efficacy of methylprednisolone, as a single 40-mg dose, injected into the masseter muscle upon completion of extraction of impacted lower third molars. A prospective, randomized cross-over study was made of 35 healthy patients. The difficulty of extraction was similar in all cases. The study group received 40 mg of methylprednisolone injected into the masseter muscle via the intrabuccal approach, immediately after suturing of the surgical wound. The control group received no intramuscular corticoid. Evaluations were made of postoperative pain, trismus and swelling. Oral aperture was measured, along with the following distances for the assessment of swelling: tragus-lip commissure, gonion-lip commissure and gonion-external canthus of the eye, before and 2 and 7 days after surgery. The patients administered methylprednisolone showed superior results after surgery in terms of oral aperture, pain and all the facial swelling parameters, with statistically significant differences versus the controls (p<0.05). The results obtained show that 40 mg of methylprednisolone injected into the masseter muscle in the immediate postoperative period reduces swelling, trismus and pain.

RESUMEN

INTRODUCTION: Geriatric oncology (GO) is a discipline that focuses on the management of elderly patients with cancer. The Spanish Society of Medical Oncology (SEOM) created a Working group dedicated to geriatric oncology in February 2016. OBJECTIVES: The main goal of this study was to describe the current situation in Spain regarding the management of elderly cancer patients through an online survey of medical oncologists. METHODS: A descriptive survey was sent to several hospitals by means of the SEOM website. A personal e-mail was also sent to SEOM members. RESULTS: Between March 2016 and April 2017, 154 answers were collected. Only 74 centers (48%) had a geriatrics department and a mere 21 (14%) medical oncology departments had a person dedicated to GO. The vast majority (n = 135; 88%) had the perception that the number of elderly patients with cancer seen in clinical practice had increased. Eighteen (12%) oncologists had specific protocols and geriatric scales were used at 55 (31%) centers. Almost all (92%) claimed to apply special management practices using specific tools. There was agreement that GO afforded certain potential advantages. Finally, 99% of the oncologists surveyed believed it and that training in GO had to be improved. CONCLUSIONS: From the nationwide survey promoted by the Spanish Geriatric Oncology Working Group on behalf of SEOM, we conclude that there is currently no defined care structure for elderly cancer patients. There is an increasing perception of the need for training in GO. This survey reflects a reality in which specific needs are perceived.

RESUMEN

Structural and microstructural characterization combined with vibrational, rotational modes are quite important to determinate reduction degree during synthesis of reduced graphene oxide. These data and analysis support the research article "Electrochemical alternative to obtain reduced graphene oxide by pulse potential: effect of synthesis parameters and study of corrosion properties" (López-Oyama et al., 2018). The data and analysis presented here included raw data for selected reduction potentials (V SCE) and different temperatures values (°C). Transmission electron microscopy (TEM) images of the exfoliated graphite are shown to corroborate the effect of the applied voltage to obtain electrochemically reduced graphene oxide (ERGO) on commercial 304L stainless steel (304L SS). The data provided in this article has not been previously published and are available to enable critical or extended analyses.

RESUMEN

Amaxophobia, or driving phobia, is an anxiety disorder; more specifically a situational phobia (SP). Main symptoms of SP may include an excessive and irrational fear to certain stimuli, to which exposure produces high anxiety levels, as well as the development of avoidance mechanisms or confrontation, at the expense of a high distress. Its prognosis is chronic in the absence of treatment, but empirical evidence reveals a high efficacy of psychological interventions based on exposure techniques. The case of a 47 years old female requesting treatment for an intense driving fear is presented. The assessment was made through an ad hoc self-report of anxiogenic episodes, the Short Form Health Survey (SF-12), the General Health Questionnaire (GHQ-28), the Perceived Stress Scale (PSS-14), the Beck Depression Inventory (BDI) and the State-Trait Anxiety Inventory (STAI). It was conducted a cognitive-behavioral intervention based on imagination and real life exposure techniques, along with breathing and relaxation techniques. After 10 sessions her anxiety levels and her negative affects decreased significantly, allowing her to resume driving and revealing the efficacy of the intervention (AU)

RESUMEN

Specimens from sputum induction (SI) are often of insufficient volume or have poor diagnostic yield for the diagnosis of Pneumocystis carinii pneumonia (PCP). The Ballard catheter for bronchoalveolar lavage (BAL) is a disposable BAL device which is passed transnasally into the airway and wedged by sensation. Thirty consecutive episodes (21 inpatient and 9 outpatient) in 28 patients positive for HIV (15 with AIDS) were studied with SI and BAL at a tertiary-care university hospital. Six SIs yielded no specimen, and six were judged inadequate for investigation by the laboratory. The BAL return averaged 53 ml (range, 10 to 77 ml), and all specimens were excellent quality based on microscopy. Of the 10 patients (33 percent) who were PCP-positive on BAL, only 2 (6.9 percent) were detected by SI (McNemar p = 0.0078). Of 12 patients in whom SI was unobtainable or inadequate, 6 were positive for PCP on BAL. Two adequate specimens from SI were negative, but BAL specimens were positive for PCP. No patients had specimens that were positive for PCP on SI who had negative BAL specimens. The adequacy of the specimen and the PCP diagnosis with BAL were statistically superior to SI (McNemar p = 0.007). The Ballard BAL catheter allows easy transnasal access to the airway and safe BAL, with a statistically significant superior yield of specimens when compared to SI.

RESUMEN

Hantavirus pulmonary syndrome (HPS), is a rodent-borne, acute, often fulminant cardiorespiratory illness. Noncardiogenic pulmonary edema is prominent in HPS as is cardiac dysfunction. Pleural effusions are commonly noted in patients with HPS and have been thought to be exudative. This report describes the prevalence and characteristics of pleural effusions by an assessment of chest radiographs for the presence of pleural fluid and reviews all pleural fluid specimens obtained from patients with HPS. Of 23 patients treated at the University of New Mexico Hospital for HPS, 22 had evidence of pleural fluid while 4 had sampling of their pleural fluid. Two samples met criteria for an exudate by pleural fluid protein to serum protein ratio of more than 0.5; one was clearly a transudate and the other had inconsistent characteristics. The two exudative samples were obtained 7 days after admission, while the other 2 were obtained within 1 day of admission. Pleural fluid cultures were sterile, and the total of nucleated cells was less than 170/mm3, and predominately mononuclear. A hypothesis may be formulated that the pleural fluid in HPS is initially transudative, consistent with the observed cardiopulmonary dysfunction. However, following aggressive resuscitative efforts and as the acute illness resolves, fluid shifts occur as cardiac function normalizes; the pleural fluid may take on characteristics of an exudate.

RESUMEN

OBJECTIVE: To determine the contribution of the polysulfate-binding domain (PSBD) of acrosin during sperm penetration. DESIGN: To inhibit the in vitro fertilization of mouse zona-intact oocytes by using a polyclonal antibody raised against an 18-amino acid peptide of proacrosin (anti-PSBD). SETTING: Unit of Reproduction and Development, Faculty of Biological Sciences, Pontifical Catholic University of Chile. PATIENT(S): None. INTERVENTION(S): A polyclonal antibody against the 43IFMYHNNRRYHTCGGILL(60) peptide was raised in New Zealand female rabbits. The specificity of the antibody was evaluated by an ELISA. Zona-intact mouse oocytes were coincubated with capacitated spermatozoa for 3 hours in the presence of 0.63 mg/mL of the antibody or preimmune serum. As a control, we used zona-free mouse oocytes under the same experimental conditions. MAIN OUTCOME MEASURE(S): We evaluated the fertilization rate of zona-intact and zona-free mouse oocytes by phase-contrast microscopy. An oocyte was considered fertilized when at least one decondensed sperm head was found within the egg cytoplasm. We evaluated 50-60 mouse oocytes in each group in three independent experiments. RESULT(S): The anti-PSBD antibody inhibited the fertilization of zona-intact, but not zona-free, mouse oocytes, by capacitated spermatozoa. In addition, the binding of the anti-PSBD to proacrosin/acrosin in a solid-phase assay was inhibited in the presence of polysulfates (fucoidan). CONCLUSION(S): The anti-PSBD directed against the PSBD of proacrosin/acrosin inhibited the penetration of capacitated mouse spermatozoa through the zona pellucida. This antibody may be a useful tool to define the roles of the different domains of proacrosin/acrosin during gamete interaction.

RESUMEN

OBJECTIVE: To validate two widely used dyspepsia scores performed by phone interview. DESIGN: Spanish translations of the Glasgow Dyspepsia Severity Score and a Likert-scale symptomatic test were evaluated. Responsiveness to the treatment, validity of the tests, and reproducibility of tests performed by phone interview were assessed. SETTING: Gastroenterology and endoscopy unit of a county hospital. PARTICIPANTS: Group I consisted of 16 ulcer patients undergoing Helicobacter pylori eradication; Group II consisted of 29 healthy volunteers; and Group III consisted of 95 patients undergoing upper endoscopy. MEASUREMENTS: Glasgow Severity Dyspepsia Score and Likert test. RESULTS: Both tests showed adequate improvement (responsiveness) after H. pylori eradication. With regard to validity, the Glasgow and Likert test were significantly higher in 95 patients undergoing endoscopy than in 29 healthy controls. Analysis of reproducibility showed that intraobserver variation was low on both the Glasgow and Likert scores. No differences were found between consecutive tests regardless of whether both were performed by phone (24 patients) or one by phone and the other by clinical interview (40 patients). Interobserver variation analysis showed that the Glasgow test remained highly reproducible even when performed by different observers using different methods (clinical interview 8.83, phone 8.44, P = 0.12). By contrast, Likert-scale tests showed significant differences between observers for all symptoms except abdominal pain. CONCLUSIONS: (1) The Glasgow score is highly reproducible even when performed by different observers and using different methods. (2) By contrast, Likert tests show greater variability. To be reproducible in different conditions, they need to be performed by the same observer.

RESUMEN

A detailed study of the dynamics of electro-optical response has been carried out over the whole temperature range of the antiferroelectric B2 phase of a compound with bent-core shape molecules, a homolog (n=14) of the series 4-chloro-1,3-phenylene bis[4-(4-n-alkylphenylimino)benzoates]. Two types of stripe domains were observed with opposite handedness and simultaneous clock and anticlock motion of the director in the neighboring domains. The temperature dependence of the interlayer potential has been found from the threshold of the transition from the ground antiferroelectric (AF) state to the field-induced ferroelectric (F) state. The rotational viscosity gamma(phi) has been calculated from the dynamics of the field-induced azimuthal director switching between F-F and AF-F states and free relaxation of the director from F to AF state. The electro-optical response was also observed below the AF-F threshold. The latter was attributed to the soft-mode distortion of the molecular tilt angle in the vicinity of the transition from the B2 phase to the isotropic phase.

RESUMEN

Aqueous extracts of Casimiroa edulis leaves injected intravenously to 20 normal Sprague-Dawley rats produced a rapid and transitory increase in blood pressure. The amplitude of the blood pressure rise was dose dependent. The increase was statistically significant (p < or = 0.01) at a concentration of 220 mOsm/l, and was associated with a significant heart rate decrease (p < or = 0.01) probably secondary to barorreceptor stimuli. The application of 130 mOsm/l of the extract did not produce a significant increase in blood pressure, which was followed by a rapid pressure normalization. The slight increase in cardiac rate during the pressure lift was probably due to sympathetic stimuli.
