RESUMO
INTRODUCTION AND OBJECTIVES: Modular neck primary stems were introduced with the theoretical advantage of restoring the hip anatomy more precisely. However, the presence of a second junction has been associated with increased corrosion and release of metal debris. The objective of our study is to quantify of chromium and cobalt serum values, and to analyse their temporal evolution during five years. MATERIAL AND METHODS: We present a prospective series of 61 patients who underwent primary total hip arthroplasty by implantation of the H MAX-M® stem (Limacorporate, San Daniele, Italy). Serum chromium and cobalt determinations were performed at six months, two years and five years. RESULTS: Our series shows a progressive elevation in chromium levels with a significant difference between chromium values at six months (0.35±0.18) and five years (0.52±0.36), p=.01. Regarding cobalt, a statistically significant elevation is observed between six months and two years and a subsequent stabilisation of values between two and five years, with a cobalt mean at six months (1.17±0.8) significantly lower than at two (2.63±1.76) and five years (2.84±2.1), p=.001. CONCLUSION: Elevated serum cobalt levels have been observed in patients who underwent modular neck stem implantation. The results obtained in this study have limited the use of stems with a modular neck in our clinical practice.

RESUMO
The human head lice is a cosmopolitan ectoparasite that causes pediculosis. The main way of spreading lice is through direct head-to-head contact. It is popular knowledge that some individuals are more susceptible to contracting head lice than others. Reports of individuals who have never been affected by the disease are common, even living in the same environment and under the same conditions as people who regularly have lice infestations. Previous research has been carried out on the risk of this infection associated with different human factors like gender or age. However, studies on the influence of the individual hair characteristics are scarce. The objective of the study was to analyze the pediculosis risk using geographical location, gender, age and individual hair characteristics as variables. Pediculosis was diagnosed through the detection of living lice in the hair. This cross-sectional school-based epidemiological study was conducted in 310 schoolchildren aged 1 to 13 years of schools in 4 municipalities situated in the State of Paraná, Brazil. The prevalence of head louse infection in primary school students was 49.35 %. The Odds Ratio of presence of pediculosis (OR) was estimated using multivariate logistic regression analysis. The results obtained indicate that hair length and thickness increase the risk of infection. Furthermore, the inclusion of hair color, hair shape, kind of hair-scale as covariates increases the risk of pediculosis, indicating that these variables partly explain this susceptibility and that pediculosis is independent of gender. A smaller hair diameter may favor insect fixation to the hair in the nymphal phases. These results may explain why girls are a greater risk as they let their hair grow for cultural reasons, i.e., being of female gender is an agglutinating variable. The conclusions drawn may explain the discrepancies obtained in previous analyses.

OBJECTIVE: Hypertension and smoking during pregnancy have been linked to various adverse maternal and fetal outcomes. The objective of this work is to study how the smoking influences the development of hypertension, its effects on the pregnant woman, and on the newborn. MATERIALS AND METHODS: An observational study in two phases was carried out: the descriptive first phase allows characterization of the sample and the analytical second phase is a case-control nested in a retrospective cohort corresponding to pregnancy. RESULTS: A total of 712 women were included in the study. Of the 672 (94.4%) non-hypertensive women, 533 (79.3%) were non-smoking and 139 (20.7%) smoking. For the 40 (5.6%) hypertensive women, 30 (75.0%) were non-smoking and 10 (25.0%) smoking. The prevalence of hypertension was of 5.6%. Women who quit smoking before pregnancy saw a reduced risk of hypertension. For women who smoke during pregnancy, those of younger ages, with a normal body mass index, who are primiparous, employed and with a low-medium level of education have higher risk of hypertension. The risk of hypertension according to the level of physical activity during leisure time follows a "U" shape, with those who perform light physical activity at the lowest risk of hypertension. Hypertensive women have a higher risk of small for gestational age newborns. Smoking does not pose an additional risk for adverse outcomes once hypertension is diagnosed. CONCLUSIONS: Future studies should aim to determine the role of smoking habit in the appearance of hypertension in pregnancy in order to establish adequate intervention guidelines that may aid in reducing the prevalence of hypertension.

OBJECTIVE: Identify the state of sedentary lifestyle during pregnancy and the factors associated with this behavior, the possible factors of your health situation and that of the newborn. MATERIAL AND METHODS: This two-phase, cross-sectional observational study was developed at the La Fe University and Polytechnic Hospital and 228 pregnant women participated. Maternal sociodemographic characteristics were obtained using structured questionnaire and health information from the electronic medical records, as well as perinatal results of the newborn. To assess sedentary lifestyle, exercise in free time and exercise during working hours were assessed, categorizing them based on intensity (sedentary lifestyle, light activity, moderate and intense activity). RESULTS: In total, the prevalence of physical inactivity was 31.14%. The profile of this group has a lower level of education and unemployment (P<.05), presenting a higher prevalence of problems during childbirth, which required a caesarean section, as well as problems after birth in the newborn (P<.05). CONCLUSIONS: Physical inactivity is highly prevalent among pregnant women. Due to the benefits (or non-harm) attributed to exercise during pregnancy. Further efforts should be taken to overcome the barriers to promote activities among pregnant women who are younger, less well educated, and unemployed and those with multiple children and a lower income are less likely to engage in an adequate amount of physical activity, aware of the importance of doing it, resolving doubts and allaying fears that may arise from a poor understanding of the mechanism of its benefit.
RESUMO
OBJECTIVE: The objective was to evaluate the consumption of fish in pregnant women and its association with maternal and infant outcomes. MATERIAL AND METHODS: In this observational study carried out at the La Fe University and Polytechnic Hospital in Valencia, 300 pregnant women participated. The participants were divided into 2 groups according to their fish consumption during pregnancy for comparison. The χ2 test or ANOVA test were applied for comparisons for qualitative and quantitative variables respectively. RESULTS: It was observed that 49% of women consumed adequate amounts of fish during pregnancy (2 or 3 weekly servings). Significant differences were observed for iron supplementation (higher in women with inadequate fish consumption), threatened pregnancy loss (higher in women with inadequate fish consumption), infant size (better in women with adequate fish consumption), and arterial O2 pressure (better in women with adequate fish consumption). In regard to the other components of the dietary pattern, no differences were observed but the adequacy of intake for grains and white meat was very poor (less than 5.0%). CONCLUSIONS: Half of the women met the recommendations for fish intake during pregnancy and presented an overall healthier eating pattern but without statistical significance.

BACKGROUND: The addition of junctions in modular stems implies a greater susceptibility to corrosion. PURPOSE: The aim of this study is to compare serum chromium and cobalt levels after using a bimodular stem and its monoblock counterpart in primary total hip arthroplasty. Postoperative clinical scores were also compared. PATIENTS AND METHODS: A prospective cohort study between 2012 and 2015 was designed. One arm of the cohort included patients with the cementless modular neck stem H-Max M® and the other with the cementless monoblock stem counterpart H-Max S®. RESULTS: No statistically significant difference was found in chromium value between groups (p = 0.621) at two years postoperative. Cobalt value was higher in the modular group (p = < 0.001). No statistically significant difference was found in clinical postoperative scores except for the Harris Hip Score, with better results at six months in modular group (p = 0.007). CONCLUSIONS: Higher serum cobalt level in the modular group has limited the use of modular stems in our daily practice. Advantages of modular stem were not found. LEVEL OF EVIDENCE: II.

BACKGROUND AND OBJECTIVES: The head louse Pediculus humanus capitis is a cosmopolitan ectoparasite that causes pediculosis. In the study of human lice, little research focuses on embryonic development. Currently, external markers of embryonic development represent a new approach in the evaluation of ovicidal drugs. The objective of this work was to update the morphology of embryonic development and propose novel external markers to differentiate between early, medium, or late P. h. capitis eggs. METHODS: Using stereoscopic light microscopy, we describe the morphological characteristics of P. h. capitis eggs with a special focus on embryonic development. RESULTS: The morphological analysis of the eggs revealed the presence of an operculum with ten aeropyles, although no micropyles were observed. For the first time, the presence of defective eggs that were non-viable due to the apparent absence of yolk granules was documented. The early eggs presented yolk granules and developing germ bands, while the medium eggs presented an embryonic rudiment and the outlines of the eyes and limbs. In late eggs, the head with eyes and antennae, the thorax with three pairs of legs, and the abdomen with six pairs of spiracles were observed as formed structures. At the end of this stage, the embryos acquired the morphology of the nymph I stage. CONCLUSION: We propose novel biomarkers (e.g., the presence of spiracles and antennae, the proportion of the egg occupied by the embryo) to facilitate the differentiation between the developmental stages. The updated morphological characteristics of P. h. capitis eggs facilitate the standardization of toxicological tests in the quest for ovicidal drugs.

INTRODUCTION AND OBJECTIVE: Dual modularity stems seek to more precisely restore anatomy by allowing intraoperative adjustments thanks to modular necks. Our aim is to compare the radiographic length correction with the H MAX-M® Stem versus its monoblock counterpart H MAX-S®. MATERIAL AND METHODS: A prospective cohort study was carried out through consecutive sampling on patients who underwent primary total hip arthroplasty with coxarthrosis diagnosis between 2011 and 2015. One arm of the cohort included patients who were operated with a modular stem and the other with a monobloc stem. Length was measured on the anteroposterior pelvic-bearing radiograph at 6 months. The mean of the measurements obtained for each arm of the cohort were compared with each other. RESULTS: No statistically significant differences were observed in the correction of asymmetry between both groups, determined as the difference in length between the operated hip and the contralateral hip (p=.106). Nor were differences observed in postoperative length values (p=.053). It should be noted that for both the modular stem and the monobloc stem, the majority group is the one with restored length (84.1% and 80.4%, respectively; p=.001). CONCLUSION: Despite the theoretical advantage of modularity and that having interchangeable parts could be of great interest, in our study, we have not been able to demonstrate a superiority of modular designs compared to monoblock for control of postoperative leg length discrepancy.
RESUMO
INTRODUCTION: Vaccination campaigns against influenza virus achieve coverages under recommended and desired values. In current context of SARS-CoV-2 pandemic it becomes more relevant. Our objective is to evaluate the impact on vaccination coverage of a set of implementation strategies carried out. MATERIAL AND METHODS: Vaccine implementation strategies were introduced in our basic health zone as active caption of patients and schedule extension. Then the vaccination coverage achieved in the current campaign was evaluated and compared with previous in the 8th week and at the end of the campaign. Besides, a transversal study through a survey was carried out to measure the impact of the applied strategies. RESULTS: In the 8th week of the campaign significant differences were detected in the increase of vaccination coverage compared with previous years. These results were confirmed at the end of the campaign, getting a significant difference (<.05) of vaccination coverage in all the studied centers, these data support the effectivity of the applied strategies. CONCLUSIONS: The vaccine implementation strategies applied have shown effectivity, achieving an increase of until 74% in the total administered doses compared to previous campaigns and even a 15% of vaccination coverage increased in the group of patients older than 64 years; even in a pandemic context and the increasing of anti-vaccine movements.

RESUMO
INTRODUCTION AND OBJECTIVE: Dual modularity stems were introduced with the theoretical advantage of restoring hip anatomy more precisely through femoral offset and limb length adjustment. Interchangeable necks allow for intraoperative angulation, anteversion and length changes. Our objective is to study whether a better femoral offset correction is achieved with the H MAX-M® prosthesis (Limacorporate, San Daniele, Italy) compared to its monoblock counterpart. MATERIAL AND METHODS: A prospective cohort study was conducted by means of consecutive sampling on adult patients undergoing total hip arthroplasty with the diagnosis of coxarthrosis between January 2011 and December 2015. This cohort has two arms, one arm included patients who underwent modular neck arthroplasty and the other included patients who underwent monoblock total hip arthroplasty. Radiographic offset measurement of the operated hip and the contralateral hip was performed, and the difference between both values was calculated. The mean of the measurements obtained for each arm of the cohort were compared with each other. RESULTS: No statistically significant differences were observed in the difference in offset between the operated hip and the contralateral hip (P=.323). No statistically significant differences were observed in the correction of the femoral offset, determined as the difference between the operated hip and the contralateral hip (P=.323). Nor were differences observed in the postoperative offset values (P=.097). It should be noted that for both designs, the majority group is the one with restored offset (P=.001).
RESUMO
INTRODUCTION: Vertigo and dizziness are symptoms with a significant burden in the hospital and involve several specialties. There are few guidelines of radiological tests for these symptoms. AIMS: To know which profile of patients with vertigo and dizziness has neuroimaging tests, quantify and describe the radiological findings. To analyze the cost-utility of CT and MRI in the study of these patients. PATIENTS AND METHODS: Descriptive study, we selected patients referred to the hospital for vertigo and dizziness. We analyze demographic and clinical characteristics and quantify the neuroimaging tests requested. We describe the radiological findings, assess their relevance in the diagnosis and detail the cost-benefit. RESULTS: We identified 493 patients, those with neuroimaging test (60%) are older, depressed and frequented the emergency department because of vertigo. The most requested test was the cranial CT scan (5% identifies the cause of the symptom). MRI of the inner ear and cerebellopontine angle was the test that presented the most significant findings (17.7%). The 286 image tests requested for vertigo cost 56,741 euros. The cost for a positive test was 1,576 euros. CONCLUSIONS: A large number of head CT and MRI are made in patients with vertigo and dizziness. A clinical suspicion is recommended from the anamnesis and exploration to make a good selection of test to request. In more than 90% of cases, radiological findings are not shown in relation to vertigo.

INTRODUCTION: One of the most frequent complications after a total hip arthroplasty (THA) is bleeding, intravenous tranexamic acid (TXA) is used to reduce it. We considered it necessary to carry out a study to clarify which administration route is superior. MATERIAL AND METHOD: Prospective, controlled and randomized study in 2 arms carried out between February 2017 and February 2018. 15mg/kg of intravenous TXA were administered in group-A and 2gr of intra-articular TXA in group-B. The values of haemoglobin and haematocrit were evaluated at 24h-72h, blood loss volume, drained blood volume, transfusions and complications. RESULTS: 78 patients were included, 31 with intravenous treatment and 47 with intra-articular. The decrease of haemoglobin in the intravenous group was 3.15±1.64g/dl in 24h and 3.75±1.56g/dl in 72h, the haematocrit decreased by 10.4±4.17% in 24h and 11.85±4.15% in 72h. In the intra-articular group there was a haemoglobin fall of 3.03±1.30g/dl in 24h and 3.22±1.2g/dl in 72h and the haematocrit fell by 10.66±3.6% and 12,11±3.29% in 24 and 72h (P>.05). The mean drainage in 24h was 195.80ml in group-A versus 253.93ml in group-B (P>.05) and in 48h it was 225.33ml in group-A and 328.19ml in group-B (P=.009). The intravenous group lost an average of 1,505ml of blood compared to the 11,280ml of the intra-articular group. In 5.1% of the cases, transfusions were necessary. We had no secondary complications. CONCLUSIONS: The different routes of administration of TXA in THA have a similar effect in the reduction of postoperative bleeding. There was no evidence of an increase in complications.

OBJECTIVE: To evaluate the clinical results and survival of primary hip prosthesis with ceramic delta bearings (C-C) with a minimum follow-up of 5years. MATERIAL AND METHOD: A total of 205 primary hip arthroplasties performed between 2008 and 2012 were studied. The clinical results, pre-surgical and at 5years of follow-up were evaluated using the Harris Hip Score (HHS), the Short Form-36 (SF-36), the Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC), and the visual analogue scale (VAS). The position of the prosthetic components, periprosthetic osteolysis, loosening of the prosthetic components and ruptures of the ceramic components were studied radiologically. The adverse events related to bearings were recorded according to their diameter, paying special attention to prosthetic dislocations and the presence of noise. Survival with an endpoint of prosthetic revision for any cause was estimated using the Kaplan-Meier method. RESULTS: Significant improvements were obtained in the HHS (88.7% of good/excellent results), SF36, WOMAC and EVA, P<.001. There were 19 adverse events related to the prosthesis (4 periprosthetic fractures, 4 dislocations, 2 superficial infections, 1 mobilization of the cup, 2 noises, 4 aseptic loosenings and 2 breaks of the prosthetic neck); 47.3% needed revision. The cumulative survival of the prostheses was 97.5% (95%CI: 96.4-98.5). No differences were found in survival, prosthetic adverse events, noise incidence or dislocations and clinical results among the different diameters used. CONCLUSIONS: Primary hip prostheses with fourth-generation ceramic bearings showed good survival in the medium term, and good clinical results.

OBJECTIVE: To assess the radiological and functional outcome of arthrodesis of the 4th and 5th finger using the APEX™ (Extremity Medical, Parsippany,NJ)intermedullary interlocking screw system in patients with severe recurrence of Dupuytren's disease. MATERIAL AND METHOD: The DASH questionnaire and the VAS scale were used to assess the clinical outcomes. The angle of arthrodesis, fusion time and implant fixation were evaluated on x-rays. The patients were monitored for complications during surgery and the follow-up period. RESULTS: The sample comprised 6 patients. Mean follow up was 19.6 months. All of the patients presented clinical and radiological evidence of fusion at 8 weeks, with fusion angles of 30° (3) and 45° (3). There were no complications and none of the implants had to be removed. The functional outcomes in these patients were poor. CONCLUSION: The system offers a reliable method for IPJ arthrodesis at a precise angle. It promotes stable fixation that does not require prolonged immobilisation. It can be used together with other procedures on the hand with severe recurrence of DD. The functional outcomes for this group of patients using this device were poor.

OBJECTIVE: The presence of resistant microorganisms is a major cause of failure in initial empirical antimicrobial therapy. The objectives of this study are to determine the resistance profile of microorganisms that cause bacteraemia of abdominal origin and to identify whether the previous use of antibiotics and the place of acquisition of bacteraemia are risk factors associated with the presence of resistant organisms. MATERIAL AND METHODS: A clinical, observational, epidemiological, retrospective cohort study was conducted with all the adult patients admitted to a university hospital from 2011-2013. Antimicrobial resistance profiles were described and a 95% confidence interval chi-square test was used to determine whether the variables studied were risk factors in the isolation of resistant microorganisms. RESULTS: Of the 1245 patients with bacteraemia, 212 (17%) presented bacteraemia of abdominal origin. The resistance profile highlights the incidence of methicillin resistant Staphylococcus aureus (50%), coagulase-negative staphylococci resistant to linezolid (20.58%), enterococci resistant to vancomycin (3.12%), Escherichia coli resistant to third-generation cephalosporins (9.9%) and fluoroquinolones (35.64%), Klebsiella pneumoniae resistant to third-generation cephalosporins (8.33%), Pseudomonas aeruginosa resistant to fluoroquinolones and carbapenem (25% and 25% respectively) and Acinetobacter baumanii resistant to fluoroquinolones and carbapenem (100% and 100% respectively), Candida albicans resistant to fluconazole (11.11%), single Candida krusei isolate resistant to fluconazole and Candida parapsilosis resistant to echinocandins (12.5%). In our study, previous use of antibiotics had a statistically significant association with the isolation of resistant microorganisms (P=.013) but not the place of acquisition of bacteraemia (P=.239). CONCLUSION: Establishing the incidence of resistant organisms can improve empirical antimicrobial therapy in patients with bacteraemia of abdominal origin. Previous use of antibiotics was statistically significantly related to the isolation of resistant microorganisms.

OBJECTIVE: Pregabalin group (PGB) is an antiepileptic used to treat neuropathic pain. We evaluated analgesic efficacy and safety for postoperative/chronic pain, disability, and sleep quality in patients who underwent spine surgery administered with PGB, or not, during the presurgical and postsurgical periods. DESIGN: Retrospective cohort study of 60 patients (two groups with 30 patients) with full information on 50 (29 with PGB and 21 without PGB). Ten patients were dismissed as information was lacking. The PGB group (P) (29 patients) received 75 mg/12 hours before surgery, 150 mg 10 hours after surgery, and 150 mg/12 hours 3 days after surgery. The control group (C; 21 patients) took no PGB. METHODS: Neuropathic pain was assessed before surgery, and 2 and 6 months later using visual analog scales (VAS), DN4, disability (Oswestry), and sleep quality. No serious adverse events occurred with PGB. RESULTS: The median VAS pain score at rest was lower in the PGB group at 2 months postsurgery (1 vs 2, P = 0.032), as was the median DN4 score (0 vs 3, P = 0.032) and the median Oswestry disability index (ODI: 12 vs 18, P = 0.001). At 6 months postsurgery, pain scores were also lower in the PGB group for VAS (0 vs 4, P = 0.001), DN4 score (0 vs 4, P = 0.001) and the ODI (10 vs 24, P = 0.001). Improvement in the functionality and sleep quality of the PGB group was noteworthy (P = 0.018). CONCLUSIONS: PGB has analgesic/antihyperalgesic effects on postoperative neuropathic pain after surgery for lumbar disc hernia. Our findings show that this benefit increases with time.

BACKGROUND: "Green" haemodialysis management to reduce the environmental impact of haemodialysis is growing. OBJECTIVES: Dealing with hazardous waste production could heighten healthcare professionals' awareness of this problem, and improve their healthcare involvement in environmental sustainability and environmental-friendliness. DESIGN AND MEASUREMENTS: A list of for-profit outpatient haemodialysis centres in the Valencian Community (E Spain) was compiled. Data on their hazardous waste production from 2008 to 2012 through the annual waste reports issued by official organisations competent in environmental issues were collected. RESULTS: There are 22 for-profit dialysis centres, that managed the treatment for 69.1% of all dialysis patients in the region. Data were collected from 16 centres that collectively offer 350 dialysis places (33.8% of all the places in this region). Mean annual hazardous waste production per dialysis session increased by 14% during the study period: 0.640 kg per session in 2008 vs. 0.740 kg in 2012. DISCUSSION AND CONCLUSIONS: As hazardous waste production is high, we must examine the reasons why it is growing. Information about haemodialysis waste production and management is scarce and difficult to access. Having an evaluation of its production would motivate further research, especially as end-stage kidney disease is increasing, and whose main long-term treatment, haemodialysis, produces hazardous waste and employs substantial natural resources. Minimising its environmental impact is not mission impossible.

BACKGROUND AND OBJECTIVE: In the latest edition of its cancer staging manual, the American Joint Committee on Cancer (AJCC) revised the criteria for staging squamous cell carcinoma (SCC) by introducing high-risk tumor features to define tumor stage (T) and help to identify tumors with a higher risk of metastasis. The aim of this study was to investigate the characteristics associated with SCC meeting the high-risk criteria defined by the AJCC for T2 lesions. PATIENTS AND METHOD: We performed a case-case observational study in which patients with SCC were included over a period of 18 months. We collected clinical, anthropometric, and tumor data, and analyzed these using PASW Statistics (SPSS) version 18. RESULTS: One-hundred eighteen patients, the majority of whom were men, were included. Mean age was 77 years. Over 70% of the tumors were located in the head region and a majority of tumors measured 2 cm or less. The prevalence of SCC T2 was 61.9%. The risk factors significantly associated with SCC T2 were an age of over 85 years (odds ratio [OR], 4.48), location in the head and neck region (OR, 3.38), presence of solar elastosis in the peritumoral tissue (OR, 2.08), a higher tumor growth rate (>1.5 mm·wk(-1); OR, 5.73), and higher cumulative exposure to smoking (>20 pack-years, OR, 3.63). CONCLUSIONS: Advanced age, location in the head and neck region, presence of solar elastosis, high tumor growth rate, and high cumulative smoking exposure were all significantly associated with the presence of SCC T2.
