Abstract
BACKGROUND Familial papillary thyroid microcarcinoma (FPTMC) appears to be more aggressive than sporadic papillary thyroid microcarcinoma (SPTMC). However, there are authors who indicate that unicentric FPTMC has a similar prognosis to SPTMC. The objective is to analyze whether unicentric FPTMC has a better prognosis than multicentric FPTMC. DESIGN AND METHODS Type of study: National multicenter longitudinal analytical observational study. STUDY POPULATION Patients with FPTMC. STUDY GROUPS Two groups were compared: Group A (unicentric FPTMC) vs. Group B (multicentric FPTMC). STUDY VARIABLES It is analyzed whether between the groups there are: a) differentiating characteristics; and b) prognostic differences. STATISTICAL ANALYSIS Cox regression analysis and survival analysis. RESULTS Ninety-four patients were included, 44% (n = 41) with unicentric FPTMC and 56% (n = 53) with multicentric FPTMC. No differences were observed between the groups according to socio-familial, clinical or histological variables. In the group B a more aggressive treatment was performed, with higher frequency of total thyroidectomy (99 vs. 78%; p = 0.003), lymph node dissection (41 vs. 15%; p = 0.005) and therapy with radioactive iodine (96 vs. 73%; p = 0.002). Tumor stage was similar in both groups (p = 0.237), with a higher number of T3 cases in the group B (24 vs. 5%; p = 0.009). After a mean follow-up of 90 ± 68.95 months, the oncological results were similar, with a similar disease persistence rate (9 vs. 5%; p = 0.337), disease recurrence rate (21 vs. 8%; p = 0.159) and disease-free survival (p = 0.075). CONCLUSIONS Unicentric FPTMC should not be considered as a SPTMC due to its prognosis is similar to multicentric FPTMC.

Abstract
The signal transducer and activator of transcription 3 (STAT3) is a transcription factor mainly activated by phosphorylation in either tyrosine 705 (Y705) or serine 727 (S727) residues that regulates essential processes such as cell differentiation, apoptosis inhibition, or cell survival. Aberrant activation of STAT3 has been related to development of nearly 50% of human cancers including clear cell renal cell carcinoma (ccRCC). In fact, phosho-S727 (pS727) levels correlate with overall survival of ccRCC patients. With the aim to elucidate the contribution of STAT3 phosphorylation in ccRCC development and progression, we have generated human-derived ccRCC cell lines carrying STAT3 Y705 and S727 phosphomutants. Our data show that the phosphomimetic substitution Ser727Asp facilitates a pro-tumoral phenotype in vitro, in a Y705-phosphorylation-independent manner. Moreover, we describe that STAT3 phosphorylation state determines the expression of different subsets of target genes associated with distinct biological processes, being pS727-dependent genes the most related to cellular hallmarks of cancer. In summary, the present study constitutes the first analysis on the role of overall STAT3 phosphorylation state in ccRCC and demonstrates that pS727 promotes the expression of a specific subset of target genes that might be clinically relevant as novel biomarkers and potential therapeutic targets for ccRCC.

Abstract
Triple negative breast cancer is considered as the worst aggressive subtype with poor prognosis. Recent studies suggest a hereditary component is involved in TNBC development, especially in young patients. However, genetic spectrum remains unclear. Our purpose was to evaluate the usefulness of multigene panel testing in triple negative patients compared to overall breast cancer cases as well as contributing to elucidate which genes are most implicated in triple negative subtype development. Two breast cancer cohorts, comprising 100 triple negative breast cancer patients and 100 patients with other breast cancer subtypes, were analyzed by Next-Generation Sequencing using an On-Demand panel which included 35 predisposition cancer genes associated with inherited cancer susceptibility. The percentage of germline pathogenic variant carriers was higher in the triple negative cohort. ATM, PALB2, BRIP1 and TP53 were the most non-BRCA mutated genes. Moreover, triple negative breast cancer patients without family history related who were identified as carriers were diagnosed at significantly earlier age. As conclusion, our study reinforces the usefulness of multigene panel testing in breast cancer cases but specifically in those with triple negative subtype regardless family history.

Abstract
Violacein is an important natural antimicrobial pigment that is mainly produced by Chromobacterium violaceum and Janthinobacterium lividum. It presents a significant range of effects against phytopathogenic and human fungi, besides being featured as having low toxicity, and by its important ecological role in protecting amphibian species and applications in dyed medical fabric. The hypothesis about violacein's action mechanisms against mucormycosis (Rhizopus arrhizus) and candidiasis (Candida auris) is herein discussed based on data available in the scientific literature.

Abstract
Neuromuscular junctions (NMJ) regulate cholinergic exocytosis through the M1 and M2 muscarinic acetylcholine autoreceptors (mAChR), involving the crosstalk between receptors and downstream pathways. Protein kinase C (PKC) regulates neurotransmission but how it associates with the mAChRs remains unknown. Here, we investigate whether mAChRs recruit the classical PKCβI and the novel PKCε isoforms and modulate their priming by PDK1, translocation and activity on neurosecretion targets. We show that each M1 and M2 mAChR activates the master kinase PDK1 and promotes a particular priming of the presynaptic PKCβI and ε isoforms. M1 recruits both primed-PKCs to the membrane and promotes Munc18-1, SNAP-25, and MARCKS phosphorylation. In contrast, M2 downregulates PKCε through a PKA-dependent pathway, which inhibits Munc18-1 synthesis and PKC phosphorylation. In summary, our results discover a co-dependent balance between muscarinic autoreceptors which orchestrates the presynaptic PKC and their action on ACh release SNARE-SM mechanism. Altogether, this molecular signaling explains previous functional studies at the NMJ and guide toward potential therapeutic targets.

Abstract
We studied how the South American sea lion (SASL, Otaria flavescens) interacts with the operation of an artisanal fishery of Chinook salmon, a non-native species in Chile, using a combination of biological and social approaches, including a valuation by fishers about this interaction. During austral summer of 2019, an observer onboard artisanal fishing boats characterized the attack behavior of SASLs to gillnet-captured Chinook salmon during 33 hauls and analyzed which factors may affect the intensity of attacks. To analyze the relationship between fishers and SASLs, a Likert scale about the perception and views about nature was applied. A total of 23 interviews—including 35 open and 16 closed questions—with fishers were conducted to describe how they perceived the interactions with SASLs. Interactions with SASLs were recorded in 35% of the fishing events and varied depending on both operational factors, such as the number of boats, as well as environmental factors, such as moon’s luminosity. Even though SASL interactions resulted in seven fish (~ 70 kg) damaged of a total catch of 2815 kg (2.5%) during the survey, boats with a damaged catch by SASL lost up to 11% of their revenue. This is consistent with 87% of the interviewed fishers who considered that the conflict with the SASL negatively impacts their activity and results in economic losses. A negative perception towards SASLs likely results from personal experience and revenue loss, even though impacts of SASL interactions at the scale of the entire fishery may be less important. While older fishers with less formal education have a productivist and instrumental focus, younger fishers with a more sustainable and conservationist view of fishing offer an opportunity to lead an improved local understanding of the relationship between salmon, SASLs, and humans.

Abstract
OBJECTIVES The objective of this study is to analyze the impact (in terms of safety and saving of hospital costs) of the implementation of a new protocol for the correction of pelvic organ prolapse (POP) by minimally invasive sacrocolpopexy (MISC) with 24-hour hospital stay. MATERIAL AND METHODS Prospective observational study of the first 78 MISC procedures performed consecutively. 46 procedures (59%) were performed with 24-hour hospital stay, and 32 (41%) required more than 24hours. The postoperative complications were determined for each group: visits to the Emergency Department, reoperations, and the average cost per procedure regarding hospital stay and ER visits. The cost model was established according to the data of the Analytical Accounting System of the Jiménez Díaz Foundation Hospital and of the Official State Gazette of Madrid. RESULTS There were no differences regarding intraoperative or postoperative complications between both groups. The number of visits to the Emergency Department, reinterventions or hospital re-admissions was lower in the 24-hour hospital stay group, without reaching statistical significance. The implementation of the MISC protocol with 24-hour hospital stay represented a saving of 607.91€ per procedure in hospital costs. CONCLUSIONS Correction of the POP with MISC with a 24-hour hospital discharge policy was feasible and safe in at least 59% of the patients, with similar complications, visits to the Emergency Department or hospital readmission rates.

BACKGROUND TNM staging of cancer is used to establish the treatment and prognosis for cancer patients, and also allows the assessment of screening programmes and hospital performance. Collection of staging data is becoming a cornerstone for cancer registries. The objective of the study was to assess the completeness of T, N, M and stage grouping registration for all cancers in the Mallorca Cancer Registry in 2006-2008 and to explore differences in T, N, M and stage grouping completeness by site, gender, age and type of hospital. METHODS All invasive cancer cases during the period 2006-2008 were selected. DCO, as well as children's cancers, CNS, unknown primary tumours and some haematological cases were excluded. T, N, M and stage grouping were collected separately and followed UICC (International Union Against Cancer) 7th edition guidelines. For T and N, we registered whether they were pathological or clinical. RESULTS Ten thousand two hundred fifty-seven cases were registered. After exclusions, the study was performed with 9283 cases; 39.4 % of whom were women and 60.6 % were men. T was obtained in 48.6 % cases, N in 36.5 %, M in 40 % and stage in 37.9 %. T and N were pathological in 71 % of cases. Stage completeness exceeded 50 % in lung, colon, ovary and oesophagus, although T also exceeded 50 % at other sites, including rectum, larynx, colon, breast, bladder and melanoma. No differences were found in TNM or stage completeness by gender. Completeness was lower in younger and older patients, and in cases diagnosed in private clinics. CONCLUSIONS T, N, M and stage grouping data collection in population-based cancer registries is feasible and desirable.

Abstract
OBJECTIVES The purpose of this study was to develop a new brief, comprehensive geriatric assessment scale for older patients diagnosed with different hematological malignancies, the Geriatric Assessment in Hematology (GAH scale), and to determine its psychometric properties. MATERIALS AND METHODS The 30-item GAH scale was designed through a multi-step process to cover 8 relevant dimensions. This is an observational study conducted in 363 patients aged≥65years, newly diagnosed with different hematological malignancies (myelodysplasic syndrome/acute myeloblastic leukemia, multiple myeloma, or chronic lymphocytic leukemia), and treatment-naïve. The scale psychometric validation process included the analyses of feasibility, floor and ceiling effect, validity and reliability criteria. RESULTS Mean time taken to complete the GAH scale was 11.9±4.7min that improved through a learning-curve effect. Almost 90% of patients completed all items, and no floor or ceiling effects were identified. Criterion validity was supported by reasonable correlations between the GAH scale dimensions and three contrast variables (global health visual analogue scale, ECOG and Karnofsky), except for comorbidities. Factor analysis (supported by the scree plot) revealed nine factors that explained almost 60% of the total variance. Moderate internal consistency reliability was found (Cronbach's α: 0.610), and test-retest was excellent (ICC coefficients, 0.695-0.928). CONCLUSION Our study suggests that the GAH scale is a valid, internally reliable and a consistent tool to assess health status in older patients with different hematological malignancies. Future large studies should confirm whether the GAH scale may be a tool to improve clinical decision-making in older patients with hematological malignancies.

Abstract
Advanced thyroid carcinoma is an infrequent tumor entity with limited treatment possibilities until recently. The extraordinary improvement in the comprehension of genetic and molecular alterations involving the RAS/RAF/mitogen-activated protein kinase and phosphatidylinositide 3-kinase/Akt/mammalian target of rapamycin signaling and interacting pathways that are involved in tumor survival, proliferation, differentiation, motility and angiogenesis have been the rationale for the development of new effective targeted therapies. Data coming from phase II clinical trials have confirmed the efficacy of those targeted agents against receptors in cell membrane and cytoplasmic molecules. Moreover, four of those investigational drugs, vandetanib, cabozantinib, sorafenib and lenvatinib, have reached a phase III clinical trial with favorable results in progression-free survival and overall survival in medullary thyroid carcinoma and differentiated thyroid carcinoma. Further analysis for an optimal approach has been conducted according to mutational profile and tumor subtypes. However, consistent results are still awaited and the research for adequate prognostic and predictive biomarkers is ongoing. The following report offers a comprehensive review from the rationale to the basis of targeted agents in the treatment of thyroid carcinoma. In addition, current and future therapeutic developments by the inhibition of further molecular targets are discussed in this setting.

Abstract
AIM The MLH1 promoter contains a common single nucleotide polymorphism (-93 guanine > adenine) located in an essential region for maximum transcriptional activity. This has been associated with an increased risk of microsatellite instability (MSI) colorectal cancer. The aim of the study was to compare the distribution of MLH1 -93G>A genotypes between patients with familial colon cancer, sporadic colon cancer and healthy subjects. METHOD We genotyped 200 familial colon samples, 183 cases of sporadic colon cancer and 236 control subjects. MSI was analysed. RESULTS The GA genotype was under-represented in patients with familial colon cancer, whereas the AA genotype was over-represented in cases of sporadic colon cancer. A greater frequency of the MLH1 GA genotype was found in the cancer cases with MLH1 focal immunohistochemistry (IHC) for anti-MLH1 antibody. When we compared genotype distribution in the familial colorectal cancer cases with and without MSI, we failed to detect any correlation, although the GA genotype is more frequent in cases with MSI. CONCLUSION There is a relationship between the MLH1 -93G>A polymorphism in the homozygous state and the risk of sporadic colorectal cancer. The variant MLH1 -93G>A appears to be related to cases with focal IHC activity more than to complete absence of the MLH1 protein in the tumour tissue.

Abstract
Cancer risks and medical management of Lynch syndrome (LS) differ from other hereditary or familial clustering of colorectal cancer. Differential diagnosis has improved as a result of the growing clinical and molecular knowledge about LS. Appropriate application of these advances in several scenarios constitutes a decision-making process to further decide germ-line testing with accuracy and efficiency. However, an only molecular-screening algorithm, with a limited number of steps and choices, may be difficult to devise. How, when, where and at what expense to use the different diagnostic tools remain dynamic and changeable under different circumstances. From a clinical point of view, it is advisable to discuss conflicting aspects to guide LS diagnosis.

Abstract
OBJECTIVES Obese patients may have special characteristics in the urinary stones formed, as the body mass index (BMI) may also be a predictive factor in lithiasic recurrence. We aim to evaluate and compare the lithiasic characteristics according to the different BMI categories, also considering the likelihood of lithiasic recurrence in presence of age and gender covariables. MATERIAL AND METHODS Retrospective, cross-sectional analysis on 346 lithiasic patients, 96 (27.7%) had low-normal weight, 151 (43.6%) overweight, and 99 (28.6%) obesity. The Chi-square and ANOVA tests were used. Survival analysis for the calculation of likelihood of lithiasic recurrence (yes/no) was made based on time on 158 patients in whom complete resolution of the initial stone was achieved by the Kaplan Meier method. Comparisons between the different categories of BMI were made using the log-Rank, Breslow and Tarone-Ware tests. Multivariate analysis was also made with the Cox regression model, introducing the covariables of age and gender. RESULTS A significant growing linear tendency has been demonstrated between multiplicity and BMI (p=0.03). The variables size and composition did not show significant differences between the groups. Median follow-up of 158 patients included in the survival analysis was 1866 days (95% CI 1602.5-2129.5). Eighteen (11.4%) of them recurred, without finding significant differences between groups: 4 low-normal weight (9.8%), 10 overweight (14.1%) and 4 obese (8.7%). The multivariate analysis also did not show a significant influence of the BMI on lithiasic recurrence (p=0.86; HR =1.06; 95% CI: 0.56-2.03). CONCLUSION A significant influence of BMI was shown on lithiasic multiplicity on diagnosis, although not on lithiasic recurrence based on time. It seems to be necessary to carry out studies in larger samples to calculate the true influence of BMI on lithiasic recurrence.

Abstract
BACKGROUND Propofol and sevoflurane act on the GABA(A) receptor, modulating the function of this receptor in an additive manner. The pharmacodynamic interaction of both drugs considering their effect on EEG activity analysed by the bispectral index (BIS) was identified as additive, but this has not been studied in a clinical setting. The objective of this study was to analyse the pharmacodynamic interaction of propofol and sevoflurane on BIS using a surface response model in patients undergoing general anaesthesia with i.v. induction and inhalation maintenance. METHODS We performed a prospective study in 24 patients undergoing general anaesthesia with propofol induction and sevoflurane maintenance. Anaesthetic depth was measured with a BIS VISTA Bilateral monitor. Propofol biophase concentration was determined using a three-compartment pharmacokinetic model, and sevoflurane end-tidal concentration was measured continuously. The response surface model described by Minto and colleagues was used to analyse the interaction. Statistical analysis was performed with Excel 2002 and SPSS v11.0. RESULTS The mean value of U(50)(theta) was 0.956 (sd 0.029) in the overall estimated data, and remained within the predefined range for all ratios of the drugs, fulfilling the criterion of additivity. The median of the weighted residuals between the actual BIS value and the BIS value predicted by the model was -5.926%. CONCLUSIONS Under the study conditions, it was confirmed that sevoflurane and propofol have an additive effect on BIS, with no evidence suggesting the existence of a synergistic effect for the concentrations of both drugs typically used in clinical practice.

Abstract
The distribution of BRCA1 and BRCA2 germ line mutations in breast/ovarian cancer families varies among different populations, which typically present a wide spectrum of unique mutations. Splicing mutation 5272-1G>A of BRCA1 and frameshift mutation 5374delTATG of BRCA2 are highly prevalent mutations in Castilla-León (Spain), accounting for 18.4% and 13.6% of BRCA1 and BRCA2 positive families, respectively. To test the presence of founder effects, 9 Spanish 5272-1G>A and 13 5374delTATG families were genotyped with polymorphic markers linked to BRCA1 or BRCA2. All the 5272-1G>A families shared a common haplotype in eight markers (1.1 Mb region) and the mutation age was estimated in 15 generations (approximately 380 years). A conserved haplotype associated to 5374delTATG was observed in four markers (0.82 Mb). The mutation occurred approximately 48 generations ago (approximately 1200 years). Each mutation likely arose from a common ancestor that could be traced to a small area of Castilla-León and expanded to other Spanish regions. They can have a significant impact on the clinical management of asymptomatic carriers as well as on the genetic screening strategy to be followed in populations with Spanish ancestries.

Abstract
Background: The TP53 pathway, in which TP53 and its negative regulator MDM2 are the central elements, has an important role in carcinogenesis, particularly in BRCA1- and BRCA2-mediated carcinogenesis. A single nucleotide polymorphism (SNP) in the promoter region of MDM2 (309T>G, rs2279744) and a coding SNP of TP53 (Arg72Pro, rs1042522) have been shown to be of functional significance. Methods: To investigate whether these SNPs modify breast cancer risk for BRCA1 and BRCA2 mutation carriers, we pooled genotype data on the TP53 Arg72Pro SNP in 7011 mutation carriers and on the MDM2 309T>G SNP in 2222 mutation carriers from the Consortium of Investigators of Modifiers of BRCA1/2 (CIMBA). Data were analysed using a Cox proportional hazards model within a retrospective likelihood framework. Results: No association was found between these SNPs and breast cancer risk for BRCA1 (TP53: per-allele hazard ratio (HR)=1.01, 95% confidence interval (CI): 0.93–1.10, Ptrend=0.77; MDM2: HR=0.96, 95%CI: 0.84–1.09, Ptrend=0.54) or for BRCA2 mutation carriers (TP53: HR=0.99, 95%CI: 0.87–1.12, Ptrend=0.83; MDM2: HR=0.98, 95%CI: 0.80–1.21, Ptrend=0.88). We also evaluated the potential combined effects of both SNPs on breast cancer risk, however, none of their combined genotypes showed any evidence of association. Conclusion: There was no evidence that TP53 Arg72Pro or MDM2 309T>G, either singly or in combination, influence breast cancer risk in BRCA1 or BRCA2 mutation carriers.

Abstract
INTRODUCTION Autosomal recessive diseases with mental retardation are disorders that affect autosomes, and their genetic expression occurs in individuals who are homozygotic for a mutation, while heterozygotic subjects are unaffected carriers. If both parents are carriers, the theoretical possibility of their children also being carriers is 50%, the risk of the children being affected by the disease is 25%, and there is a 25% chance of their being healthy. They are an important source of mental deficiencies and inborn errors of metabolism (IEM) are some of their characteristic syndromes. DEVELOPMENT The genetic disorders known as IEM can be classified according to the metabolism they affect, that is, purines, pyrimidines, amino acids, and so on. One of the lysosomal disorders is Tay-Sachs disease, which is rare among the general population but is very frequent in populations with a high rate of consanguinity, such as the Ashkenazi Jews. One of the most notable disorders affecting the metabolism of amino acids is the case of phenylketonuria due to mutations in the phenylalanine hydroxylase gene (PAH). It accounts for 0.5-1% of mental diseases and appears with a frequency rate of between 1/11,500 and 1/14,000 in newborn infants. Its early diagnosis through neonatal screening programmes makes it possible to start administering a phenylalanine-free diet and thus prevent mental retardation. CONCLUSIONS Knowledge of this kind of autosomal diseases with neurological involvement, together with their correct and early diagnosis, makes it possible to establish suitable treatment regimens in some cases and to carry out genetic counselling in all of them.

Abstract
To consider what a correct preventive approach for osteoporosis should be in the management of the asymptomatic post-menopausal woman. Literature review and opinions on this issue shared by a group of professionals with wide clinical experience in health care for peri- and post-menopausal women. There is agreement that osteoporosis combines most of the ideal requirements for the application of a preventive strategy. The natural evolution of this pathology leads to serious events, fractures, but it provides various opportunities for prevention. Osteoporosis can be avoided and in particular, fractures due to bone fragility and their consequences should be avoided. Nowadays, there are different courses of action (pharmacological or otherwise) with proven effectiveness for the prevention osteoporosis and osteoporotic fractures. However, long-term action is required for a broad segment of the population, so a certain strategy is necessary to guide clinical decisions for different profiles of women. There is little data in the literature to justify a different preventive approach, depending on the presence or absence of vasomotor symptoms, but clinical experience shows that their absence is not associated with a lower osteoporosis risk. Different strategies have been tried for the prevention of osteoporosis and its complications and some of them might be effective, but there is no analysis with conclusive results. A preventive strategy for osteoporosis should be included in the management of asymptomatic post-menopausal women, because this is an avoidable pathology and the absence of vasomotor symptoms does not reduce the risk of its development. Nevertheless, a well-designed cost-benefit analysis is needed to justify the implementation of any strategy at a community level, because adverse effects and economic cost could exceed the benefits obtained in low fracture risk populations.

Abstract
An experimental model of microsurgical cholestasis is studied as an alternative to the most frequently used surgical techniques, based on the section of the common bile duct. This microsurgical technique consists of the resection of the extrahepatic biliary tract, that is, of the common bile duct in continuity with the bile ducts that drain the four lobes of the rat liver. At 30 days of evolution, rats with microsurgical cholestasis do not develop biliary pseudocysts or intraperitoneal hilar hepatopulmonary abscesses and show an increase (p < 0.001) in total bilirubin (9.50 +/- 1.50 mg/dL vs. 1.60 +/- 0.35 mg/dL), bile acids (225 +/- 87 micromol/L vs. 12.5 +/- 14.50 micromol/L), gamma-glutamyltranspeptidase (375 +/- 143 U/L vs. 8 +/- 11 U/L), and alkaline phosphatase (73 +/- 25 U/L vs. 23 +/- 4 U/L) levels. The histological study shows fibrosis with biliary proliferation. The microsurgical cholestasis technique is a valid alternative to other techniques and can be an adequate experimental model for the study of etiopathogenic mechanisms of obstructive jaundice and especially to study extrahepatic biliary atresia.

Abstract
AIMS AND BACKGROUND Coronary endothelial dysfunction improves after acute oestradiol treatment in women with angina and normal coronary angiograms. We sought to analyse whether this effect is also seen in the peripheral circulation and whether it is sustained after a mid-term period of treatment. METHODS We studied 20 women with angina, signs suggestive of myocardial ischaemia and normal coronary angiograms. In five of them, coronary and peripheral endothelial functions were studied at baseline. Brachial artery flow-mediated dilation was reanalysed after 24 h of transdermal oestradiol treatment. In the other 15 women, brachial artery vasoreactivity was studied at baseline and after a 6-week period of treatment with transdermal oestradiol and medroxyprogesterone (HRT) or placebo in a double-blinded crossover fashion. RESULTS An abnormal coronary artery response to acetylcholine was observed in all women as well as impaired brachial flow-mediated dilation. Brachial flow-mediated dilation significantly increased after 24 h of oestradiol treatment (4.8+/-0.8% vs 0.06+/-0.6%, P<0.001). Peripheral flow-mediated dilation also increased after a 6-week period of HRT compared with baseline (4.1+/-3% vs 0.4+/-1%, P<0.01) and placebo treatment (4.1+/-3% vs 0.6+/-1.7%, P<0.01). CONCLUSION Impaired endothelium-dependent vasodilation exists both at the coronary and peripheral circulation in post-menopausal women with angina and normal coronary angiograms. Flow-mediated dilation improves in these women after short and mid-term therapy with transdermal oestradiol irrespective of concomitant progesterone use.

Abstract
In this study a cELISA for the diagnosis of brucellosis due to B. melitensis in sheep and goats was evaluated and its capability of discriminating vaccinated from infected animals was assessed. Information is provided indicating that the cELISA has a diagnostic sensitivity (99.4%) and specificity (98.9%) in sheep and goats comparable to that of many standard indirect ELISA methods. In addition, the test proved able to distinguish between vaccinated and infected animals with an accuracy of up to 90% and results reproducibility of 93%. It was concluded that the cELISA could be useful for differentiation of Rev.1 vaccinated and naturally infected sheep and goats.

Abstract
The objective of this study was to evaluate the effect of surgical menopause and hormone replacement therapy (HRT) on the new biochemical markers of bone turnover. Fourteen women who had undergone surgical menopause and began HRT 3 months after surgery were recruited for a 1-year study. Results were compared with a control group of 31 healthy premenopausal women of similar age. Serum samples were obtained to determine total alkaline phosphatase, bone alkaline phosphatase, propeptides carboxy- and amino-terminal of type I procollagen (PICP, PINP), osteocalcin, tartrate-resistant acid phosphatase, and carboxy-terminal telopeptides of type I collagen (ICTP and serum CTX). Urine samples were analyzed for hydroxyproline, pyridinoline, deoxypyridinoline, alpha- and beta-carboxy-terminal telopeptides of type I collagen (alpha-CTX and beta-CTX), and amino-terminal telopeptide of type I collagen (NTX). Determinations were performed after 3 months of surgical menopause and after 3 and 9 months of HRT. All biochemical markers increased after menopause, and most of them normalized after 9 months of HRT. Serum PINP showed the highest proportion of increased values after surgery among bone formation markers (62%), as well as the highest mean percent increase (101%). Among bone resorption markers in postmenopausal women, urinary beta-CTX, alpha-CTX, NTX, and serum CTX showed the highest proportion of increased values (100%, 67%, 58%, 58%, respectively) as well as the greatest mean percent increase. They were also the markers with the most marked response to HRT. In conclusion, serum PINP is the most sensitive marker of bone formation, whereas beta-CTX is the most sensitive marker of bone resorption after surgical menopause. In addition, both markers showed the highest response after HRT.

Abstract
AIM to prospectively determine the diagnostic accuracy of magnetic resonance cholangiopancreatography (MRCP) in the evaluation of the normal and diseased pancreatic duct. METHODS patients seen during a 6-month period with a diagnosis of biliary tract or pancreatic disease underwent endoscopic retrograde cholangiopancreatography (ERCP) after a previous MRCP. The pancreatic duct was evaluated with both techniques in 37 patients. RESULTS the pancreatic duct appeared normal in ERCP in 27 patients, and also appeared normal in MRCP in 25 of these patients (specificity 93%). ERCP showed moderate-severe pancreatic duct dilation in 8 patients, in whom the same diagnosis was reached with MRCP (sensitivity 100%). The causes of dilation were chronic pancreatitis (2 patients), pancreatic cancer (3 patients) and ampullary tumor (2 patients); in 1 patient the findings with both techniques were suggestive of neoplasm of the head of the pancreas or focal chronic pancreatitis. Pancreas divisum was diagnosed in 2 patients by both methods, and the predominant dorsal duct as well as the ventral duct were visualized by MRCP. CONCLUSIONS MRCP is an accurate technique for evaluating the normal or diseased pancreatic duct, and for determining the underlying disease.

Abstract
An study was carried out of the association of Basedow disease (B) and Hashimoto toxicosis (H), the response to the usual therapeutic regimens and prognostic factors for the clinical course. Seventy-one patients with the diagnosis of autoimmune hyperthyroidism were included. Sixty-one of them were prospectively followed for 8.4 +/- 2.2 years (range: 5-10 years). All patients were treated following the same criteria with antithyroid drugs and aggressive therapy (radioiodine or surgery). Two groups were differentiated: group H (62%), with titers of antimicrosomal antibodies (AMSA) > or = 1/6,400 and a positive perchlorate discharge test (PDT), and group B, with AMSA titers < 1/6,400 and negative PDT. During follow-up a three-fold number of relapses was observed in group H compared with group B, a higher frequency towards spontaneous hypothyroidism in the evolution (23% in H versus 0% in B), and higher requirements of radioiodine in H than in B. In our experience, H makes up and important percentage of autoimmune hyperthyroidism (62%) with a clinical course characterized by a higher number of relapses, higher requirements of radioiodine and a higher rate towards spontaneous hypothyroidism.

Abstract
BACKGROUND Long permanent remissions in malignant hematopoietic disorders can often be achieved by autologous bone marrow transplantation (ABMT) or by allogenic bone marrow transplantation (BMT). Previous studies have shown that such therapies may induce osteoporosis due to iatrogenic ovarian failure. The administration of hormone replacement therapy (HRT) in these women could prevent the adverse effects of long-term ovarian failure without remarkable side effects. The aim of this study was to evaluate how the bone mass is affected by HRT in patients undergoing ABMT or BMT adjusting the results for age, weight, and height. SUBJECTS AND METHODS Thirteen women with previous ABMT/BMT were treated with a standard dose (0.625 mg/day) of conjugated equine estrogen (CEE) or with 50 micrograms/day of 17-beta-estradiol in transdermal therapeutic systems (TTS) plus 5 mg/day of medroxyprogesterone acetate sequentially added to the last 12 days of estrogen therapy. Bone mass was measured prior to and 12 months following HRT. Blood samples were collected before therapy and during the 6th and 12th treatment months. RESULTS The mean time elapsed between bone transplantation and HRT initiation was 13.0 months (range 3-26 months). Before treatment nine patients were osteopenic and after HRT bone mass increased in all cases. Following ABMT/BMT, hepatic hyperenzymemia was detected in three patients. After 6 and 12 months of treatment no significant changes were observed in hepatic enzymes. CONCLUSION Although hepatic hyperenzymemia is commonly considered as a contraindication for HRT, our results suggest that HRT is safe for these patients and that such therapy should be initiated after transplantation in women to prevent adverse effects of long-term ovarian failure.

Abstract
On the basis that gonadotrophin-releasing hormone agonists (GnRHa) induce a significant but transient shrinkage of leiomyomas and that oral contraceptive use may be associated with a decreased risk of fibroids, we tested the hypothesis that sequential GnRHa/low-dose oral contraceptive treatment could be a therapeutic alternative in perimenopausal women with uterine fibroids. Six premenopausal women with leiomyomata uteri were treated with D-tryptophan-6-luteinizing hormone-releasing hormone (D-Trp-6-LHRH) depot (Decapeptyl 3.75) for 6 months and demonstrated a significant reduction in mean uterine volume. A low-dose oral contraceptive containing 30 micrograms of ethinyl oestradiol plus 150 micrograms of desogestrel was given during the ensuing 12 months. When GnRHa therapy was discontinued, there was a rapid regrowth of the uterine fibroids and the uterine volume had reached, or even exceeded, pretreatment values by the eighth to 12th month of contraceptive therapy. Sequential GnRHa/low-dose oral contraceptive treatment is not a useful tool for leiomyomata uteri.

Abstract
BACKGROUND It is well known that progestins given in sufficient dosage reduce the risk of endometrial cancer and endometrial hyperplasia. It is also not uncommon that patients receiving hormone replacement therapy (HRT) require endometrial biopsy in order to evaluate the effects of oestrogens and progestogens on endometrium. However, endometrial biopsy is often associated with pain and discomfort, and transvaginal sonography has been suggested as a new and painless method of monitoring the effects of HRT on the endometrium. METHODS Transvaginal ultrasonography was performed in a series of women on several regimens of HRT immediately prior to endometrial biopsy (Cornier cannula). We correlated the morphology and thickness of the endometrium as assessed by transvaginal ultrasonography with the endometrial histology. Patients were assigned into four groups. The first (n = 15) received 0.6 mg/day of conjugated equine oestrogen (CEE) cyclically and the second (n = 6) received 50 micrograms/day of transdermal oestradiol cyclically. All these groups also received 5 mg of medroxy-progesterone acetate (MPA) sequentially for the last 12 days of HRT, while the third therapy group (n = 7) received 0.625 mg/day of CEE and 5 mg/day of MPA uninterruptedly. The fourth group (n = 8) constituted a treatment-free control group. In total 36 biopsies were taken. Our initial results suggest that endometrial thickness under 4 mm measured by ultrasonography is not associated with endometrial abnormalities and that transvaginal ultrasonographic scanning of the endometrium may be a useful tool in determining which patients require endometrial histologic evaluation and perhaps in detecting those who need adjustment in the progestin dosage.

Abstract
BACKGROUND The magnitude of the problem of nosocomial infection in children has never been studied in Spain. METHODS In 1990, a nationwide cross-sectional study was conducted to determine the prevalence of nosocomial infection and associated risk factors. RESULTS Among 38,489 patients surveyed, 4081 were pediatric patients. Three hundred forty-five patients (8.4%) had active nosocomial infection at the time of the survey. Pediatric intensive care units (29.7%), hematology (23%), and special units (22%) showed the highest rates. Infections were most common in patients younger than 1 year (prevalence, 12.3%). Frequencies of nosocomial infection by site were as follows: bloodstream, 22.1%; urinary tract, 13.1%; lower respiratory tract, 12.3%; postoperative wound, 8%; gastrointestinal tract, 7.6%; skin, 6.5%; eye, 5.8%; and others 24.6%. The factors most closely associated with a higher prevalence of nosocomial infection in pediatrics were as follows: age younger than 1 year, surgery, moderate and severe baseline risk, number of diagnoses, and all categories of extrinsic risk factors. The most frequent etiologic agents were gram-positive bacteria (45.8%). CONCLUSIONS Although the overall prevalence is at an acceptable level, future efforts should be focused on developing more effective prevention strategies in specific areas.

Abstract
A case of Ebstein's anomaly with pulmonary hypoplasia diagnosed in utero by color Doppler echocardiography in a 26 weeks fetus is presented. We emphasize the importance of ultrasound in the early detection of this congenital abnormality that allowed our medical team to offer correct assistance to a severe ill child at birth.

Abstract
Using Doppler echocardiography, we have quantified the atrial contribution to ventricular filling in 22 patients with mitral stenosis in sinus rhythm without or with minimal mitral and/or aortic regurgitation. With continuous wave Doppler from apex we obtained the ventricular filling flow from which the valvular area was calculated. The product of the integrated ventricular filling waves multiplying by the valvular area was called total volume (TV). Assuming that the deceleration of the ventricular filling flow is linear and remain constant, we integrated the transmitral flow, this time without considering the atrial filling wave as if the patient was entering into atrial fibrillation. Multiplying this integration by the valvular area we obtained a second volume, atrial fibrillation volume (AFV). The atrial contribution was calculated by: 1) absolute value: TV-AFV and in 2) percent value or fraction: (TV-AFV/TV) x 100. When we correlate absolute and percent values with mitral valve area, the results were statistically significant in both cases (p less than 0.001), with an excellent regression factor both with absolute value r = 0.90 and the percent one r = 0.72. In mitral stenosis the atrial contribution to ventricular filling has an inverse relation with the grade of severity, being very low in the more severe lesions. This is why it would be doubtful that its lost (atrial contribution) is the only cause of hemodynamic deterioration that has been observed in patients who suddenly present atrial fibrillation.

Abstract
In order to evaluate diastolic regurgitant flows in atrioventricular valves, we studied by Doppler echocardiography four patients in whom electric abnormalities like third degree atrioventricular block, pacemaker dysfunction and ventricular arrhythmias with atrioventricular dissociation were detected. In all of them, mitral and tricuspid high velocity regurgitant flows were found in systole. A second regurgitant atrioventricular flow was also registered, this flow being diastolic, intermittent, and with a lower velocity profile than the systolic regurgitation. The hemodynamic importance of this diastolic regurgitant flow over the cardiac output has not been well defined; in our cases the ventricular filling was not substantially modified by diastolic regurgitant flow.
