Atresia de vías biliares: pronóstico a largo plazo

L’atrèsia de vies biliars és una colangiopatia obstructiva neonatal poc freqüent que planteja encara en l'actualitat una sèrie de problemes encara no resolts; sent la causa més freqüent de trasplantament hepàtic pediàtric. Estudiem el pronòstic a llarg termini dels pacients amb atrèsia de vies biliars després d'un maneig multidisciplinar a l'Hospital Universitari Vall d'Hebron i descrivim els resultats i la supervivència dels pacients intervinguts de Kasai requereixin o no trasplantament.

Factores predictivos de recaída sistémica y supervivencia cáncer-específica tras recaída locorregional en cáncer de mama resecado

S´ha realitzat un anàlisi retrospectiu de variables clínic-patològiques d´una sèrie de 116 malaltes diagnosticades d´una recaiguda locorregional de càncer de mama després d´una resecció quirúrgica amb mastectomía o cirurgía conservadora a l´Hospital Universitari La Fe entre els anys 1988 i 2008. La mitjana de seguiment des del diagnòstic de la recaiguda locorregional ha sigut de 60 mesos. Cinquanta-tres malaltes (45,7%) varen desenvolupar una recaiguda sistèmica amb una tasa de supervivència cáncer-específica després de la recaiguda local als 5 i 10 anys de 67 i 54% respectivament. A l´anàlisi multivariant la presència d´invasió vàsculo-linfàtica i l´afectació cutànea (cutànides) a la recaiguda varen permanèixer com a factors predictius independents de recaiguda sistèmica i supervivència càncer-específica. La presència d´aquestos factors identifica un subgrup de malaltes d´alt risc de progressió sistèmica i mort per cáncer de mama després de la recaiguda local a les que s´hauria de considerar un tractament més intensiu.

Granulomatosis de Wegener: estudio de 15 casos, supervivencia y daño crónico

La granulomatosi de Wegener i la síndrome de Churg-Strauss són vasculitis granulomatoses de petit i mitjà vas. Es diagnostiquen mitjançant clínica i biòpsia compatible, i s'associen amb anticossos anticitoplasma de neutròfils. S'ha realitzat un estudi retrospectiu (1984 - 2010) a l'Hospital Universitari Germans Trias i Pujol. Es presenten 15 pacients amb granulomatosi de Wegener. Les característiques clíniques de la present sèrie no difereixen de les descrites prèviament. Es va comparar la supervivència i el dany crònic acumulat en els pacients amb aquestes dues vasculitis. Tant la mortalitat com el dany crònic acumulat resultà superior en el grup de malalts amb granulomatosi de Wegener.

Impacto de la rotación cíclica de antibióticos sobre la etiología de las neumonías nosocomiales por gramnegativos en una unidad de cuidados intensivos (uci)

La rotació cíclica d'antibiòtics (RCA) consisteix a restringir de forma determinada i establerta un antibiòtic o classe d'antibiòtics durant un determinat període de temps, per a tornar a reintroduir-lo posteriorment. D'aquesta manera es pretén evitar l'aparició de resistències bacterianes derivades d'un ús continuat del mateix. En aquest treball, proposem la RCA com una estratègia per al control d'infeccions per gèrmens multirresistents i veure la seva influència en els gèrmens més freqüents que intervenen en les pneumònies nosocomials (NN). A través del registre ENVIN es van recollir les dades de tots els pacients ingressats a la UCI de l'Hospital Universitari la Fe durant dotze mesos consecutius. Es van dividir en 4 cicles de 3 mesos de durada cadascun d'ells. En el primer cicle es va restringir ampicilina/sulbactam, amikacina, cefalosporines i vancomicina; en el segon cicle carbapenems, amikacina i linezolid; en el tercer cicle tigeciclina, quinolones, tobramicina i linezolid i al quart i últim cicle, piperacilina/tazobactam, tobramicina i teicoplanina. Es va comparar amb els tres mesos previs al inici del treball, al qual l'ús d'antibiòtics va ser lliure. El temps global de l'estudi va ser de 15 mesos. El percentatge d'aïllaments d´Acinetobacter spp en el període basal va ser del 46,15% (n=6), de Pseudomonas aeruginosa 15,38% (n=2) i d'Escherichia coli 7, 69% (n=1). Al final de l'estudi els gèrmens aïllats van ser en un 8,57% (n=3) Acinetobacter spp i en un 37,14% (n=13) Pseudomonas aeruginosa.

Fascitis eosinofílica. A propósito de 13 casos.

Es tracta de la descripció d'una sèrie de 13 pacients amb fascitis eosinofílica diagnosticats en un hospital universitari entre 1989 i 2009. És una síndrome esclerodermiforme que es caracteritza per induració cutània i engruiximent i inflamació de la fàscia profunda. Es descriuen les característiques clíniques, el tractament rebut i l'evolució de 9 homes i 4 dones, amb una edat mitjana de 50 anys. Es va realitzar biòpsia profunda en tots els casos i els canvis van ser compatibles amb fascitis eosinofílica. Les característiques descrites en aquesta sèrie no difereixen de les descrites per altres autors.

Validation of the spanish version of the multiple sclerosis international quality of life (musiqol) questionnaire

BACKGROUND: The Multiple Sclerosis International Quality Of Life (MusiQoL) questionnaire, a 31-item, multidimensional, self-administrated questionnaire that is available in 14 languages including Spanish, has been validated using a large international sample. We investigated the validity and reliability of the Spanish version of MusiQoL in Spain. METHODS: Consecutive patients with different types and severities of multiple sclerosis (MS) were recruited from 22 centres across Spain. All patients completed the MusiQoL questionnaire, the 36-Item Short Form (SF-36) health survey, and a symptoms checklist at baseline and 21 days later. External validity, internal consistency, reliability and reproducibility were tested. RESULTS: A total of 224 Spanish patients were evaluated. Dimensions of MusiQoL generally demonstrated a high internal consistency (Cronbach's alpha: 0.70-0.92 for all but two MusiQoL domain scores). External validity testing revealed that the MusiQoL index score correlated significantly with all SF-36 dimension scores (Pearson's correlation: 0.46-0.76), reproducibility was satisfactory (intraclass correlation coefficient: 0.60-0.91), acceptability was high, and the time taken to complete the 31-item questionnaire was reasonable (mean [standard deviation]: 9.8 [11.8] minutes). CONCLUSIONS: The Spanish version of the MusiQoL questionnaire appears to be a valid and reliable instrument for measuring quality of life in patients with MS in Spain and constitutes a useful instrument to measure health-related quality of life in the clinical setting.

Impactia: automating the study of the scientific production

Introduction The Andalusian Public Health System Virtual Library (Biblioteca Virtual del Sistema Sanitario Público de Andalucía, BV-SSPA) was set up in June 2006. It consists of a regional government action with the aim of democratizing the health professional access to quality scientific information, regardless of the professional workplace. Andalusia is a region with more than 8 million inhabitants, with 100,000 health professionals for 41 hospitals, 1,500 primary healthcare centres, and 28 centres for non-medical attention purposes (research, management, and educational centres). Objectives The Department of Development, Research and Investigation (R+D+i) of the Andalusian Regional Government has, among its duties, the task of evaluating the hospitals and centres of the Andalusian Public Health System (SSPA) in order to distribute its funding. Among the criteria used is the evaluation of the scientific output, which is measured using bibliometry. It is well-known that the bibliometry has a series of limitations and problems that should be taken into account, especially when it is used for non-information sciences, such us career, funding, etc. A few years ago, the bibliometric reports were done separately in each centre, but without using preset and well-defined criteria, elements which are basic when we need to compare the results of the reports. It was possible to find some hospitals which were including Meeting Abstracts in their figures, while others do not, and the same was happening with Erratum and many other differences. Therefore, the main problem that the Department of R+D+i had to deal with, when they were evaluating the health system, was that bibliometric data was not accurate and reports were not comparable. With the aim of having an unified criteria for the whole system, the Department of R+D+i ordered the BV-SSPA to do the year analysis of the scientific output of the system, using some well defined criteria and indicators, among whichstands out the Impact Factor. Materials and Methods As the Impact Factor is the bibliometric indicator that the virtual library is asked to consider, it is necessary to use the database Web of Science (WoS), since it is its owner and editor. The WoS includes the databases Science Citation Index (SCI), Social Sciences Citation Index (SSCI) and Arts & Humanities Citation Index. To gather all the documents, SCI and SSCI are used; to obtain the Impact Factor and quartils, it is used the Journal Citation Reports, JCR. Unlike other bibliographic databases, such us MEDLINE, the bibliometric database WoS includes the address of all the authors. In order to retrieve all the scientific output of the SSPA, we have done general searches, which are afterwards processed by a tool developed by our library. We have done nine different searches using the field ‘address’; eight of them including ‘Spain’ and each one of the eight Andalusian Regions, and the other one combining ‘Spain’ with all those cities where there are health centres, since we have detected that there are some authors that do not use the region in their signatures. These are some of the search strategies: AD=Malaga and AD=Spain AD=Sevill* and AD=Spain AD=SPAIN AND (AD=GUADIX OR AD=BAZA OR AD=MOTRIL) Further more, the field ‘year’ is used to determine the period. To exploit the data, the BV-SSPA has developed a tool called Impactia. It is a web application which uses a database to store the information of the documents generated by the SSPA. Impactia allows the user to automatically process the retrieved documents, assigning them to their correspondent centres. In order to do the classification of documents automaticaly, it was necessary to detect the huge variability of names of the centres that the authors use in their signatures. Therefore, Impactia knows that if an author signs as “Hospital Universitario Virgen Macarena”, “HVM” or “Hosp. Virgin Macarena”, he belongs to the same centre. The figure attached shows the variability found for the Empresa Publica Hospital de Poniente. Besides the documents from WoS, Impactia includes the documents indexed in Scopus and in other databases, where we do bibliographic searches using similar strategies to the later ones. Aware that in the health centres and hospitals there is a lot of grey literature that is not gathered in databases, Impactia allows the centres to feed the application with these documents, so that all the SSPA scientific output is gathered and organised in a centralized place. The ones responsible of localizing this gray literature are the librarians of each one of the centres. They can also do statements to the documents and indicators that are collected and calculated by Impactia. The bulk upload of documents from WoS and Scopus into Impactia is monthly done. One of the main issues that we found during the development of Impactia was the need of dealing with duplicated documents obtained from different sources. Taking into account that sometimes titles might be written differently, with slashes, comas, and so on, Impactia detects the duplicates using the field ‘DOI’ if it is available or comparing the fields: page start, page end and ISSN. Therefore it is possible to guarantee the absence of duplicates. Results The data gathered in Impactia becomes available to the administrative teams and hospitals managers, through an easy web page that allows them to know at any moment, and with just one click, the detailed information of the scientific output of their hospitals, including useful graphs such as percentage of document types, journals where their scientists usually publish, annual comparatives, bibliometric indicators and so on. They can also compare the different centres of the SSPA. Impactia allows the user to download the data from the application, so that he can work with this information or include them in their centres’ reports. This application saves the health system many working hours. It was previously done manually by forty one librarians, while now it is done by only one person in the BV-SSPA during two days a month. To sum up, the benefits of Impactia are: It has shown its effectiveness in the automatic classification, treatment and analysis of the data. It has become an essential tool for all managers to evaluate quickly and easily the scientific production of their centers. It optimizes the human resources of the SSPA, saving time and money. It is the reference point for the Department of R+D+i to do the scientific health staff evaluation.

Central nervous system involvement at first relapse in patients with acute promyelocytic leukemia treated with all-trans retinoic acid and anthracycline monochemotherapy without intrathecal prophylaxis.

BACKGROUND The prevalence of and risk factors for central nervous system recurrence in patients with acute promyelocytic leukemia are not well established and remain a controversial matter. DESIGN AND METHODS Between 1996 and 2005, 739 patients with newly diagnosed acute promyelocytic leukemia enrolled in two consecutive trials (PETHEMA LPA96 and LPA99) received induction therapy with all-trans retinoic acid and idarubicin. Consolidation therapy comprised three courses of anthracycline monochemotherapy (LPA96), with all-trans retinoic acid and reinforced doses of idarubicin in patients with an intermediate or high risk of relapse (LPA99). Central nervous system prophylaxis was not given. RESULTS Central nervous system relapse was documented in 11 patients. The 5-year cumulative incidence of central nervous system relapse was 1.7% (LPA96 3.2% and LPA99 1.2%; p=0.09). The cumulative incidence was 0%, 0.8%, and 5.5% in low-, intermediate-, and high-risk patients, respectively. Relapse risk score (p=0.0001) and the occurrence of central nervous system hemorrhage during induction (5-year cumulative incidence 18.7%, p=0.006) were independent risk factors for central nervous system relapse. CONCLUSIONS This study shows a low incidence of central nervous system relapse in patients with acute promyelocytic leukemia following therapy with all-trans retinoic acid and anthracycline without specific central nervous system prophylaxis. Central nervous system relapse was significantly associated with high white blood cell counts and prior central nervous system hemorrhage, which emerged as independent prognostic factors.

Paper de l’ Haemophilus influenzae en les exacerbacions de la Malaltia Pulmonar Obstructiva Crònica (MPOC): tipificació molecular i factors de virulència

Objetivos: 1.-Identificar los factores clínicos y microbiológicos que ayuden a predecir la aparición de exacerbaciones en la EPOC. 2.-Diagnóstico y cuantificación de las especies bacterianas aisladas en esputo (fase de exacerbación y estable) .3.- Tipificación genotípica secuencial de las cepas de H. influenzae y P. aeruginosa. 4.- Impacto del tratamiento antibiótico en la aparición de resistencias en estos patógenos. 5.- Diseño: Estudio prospectivo (3 años). Ámbito del estudio: Hospital Universitario de tercer nivel. Pacientes con EPOC grave atendidos en la Consulta Monográfica de EPOC del Servicio de Neumología. Métodos microbiológicos: Cuantificación de la carga bacteriana en muestras respiratorias en fase estable y en exacerbación. Estudio de la sensibilidad “in vitro”. Tipificación molecular (PFGE y MLST) de H. influenzae y P. aeruginosa. Estudio de los genes de virulencia de H. influenzae mediante PCR. Resultados: Desde Febrero de 2010 a Julio de 2011 se han incluido 77 pacientes. Los microorganismos más frecuentemente aislados en fase de exacerbación fueron: P. aeruginosa (29.3%), H. influenzae (15.92%), M. catarrhalis (12.74%), S. pneumoniae (10.19%) y S. aureus (5.10%). En los 88 episodios por P. aeruginosa se detectaron 38 genotipos diferentes. En los 41 episodios por H. influenzae se detectaron 39 genotipos diferentes. El 10% de los episodios fueron polimicrobianos. Los episodios de EAEPOC y de fase estable tuvieron una distribución de microorganismos similar. Sin embargo, cuando se cuantificaron las cargas bacterianas fueron mayores en EAEPOC (intervalo 4x107 -2x108) que en fase estable (intervalo 2x105 -4x107). Conclusiones: El genotipo de las cepas de P. aeruginosa y H. influenzae aisladas en EAEPOC difieren de un paciente a otro, sin embargo la mayoría de los episodios de cada paciente están causados por un genotipo único.

Assisted reproductive technology and obstetric outcome in couples when the male partner has a chronic viral disease.

BACKGROUND Assisted reproductive technology (ART) with washed semen can achieve pregnancy with minimal risk of horizontal and vertical transmission of chronic viral diseases (CVD) such as human immunodeficiency virus (HIV), hepati- tis C virus (HCV) and hepatitis B virus (HBV) among serodiscordant couples. How- ever, few studies have been made of the use made by these couples of ARTs or of the obstetric results achieved. MATERIALS AND METHODS In this retrospective study, 93 men who were seropositive for HIV, HCV or HBV and who underwent assisted reproduction treatment at our centre (Hospital Universitario Virgen de las Nieves, Granada, Spain) were included. Washed semen was tested to detect viral particles. Non-infected women were tested before and after each treatment, as were the neonates at birth and after three months. RESULTS A total of 62 sperm samples were washed, and none were positive for the detec- tion of viral molecules. Semen samples from 34 HBV positive males were not washed since the female partner had immunity to hepatitis B. In total, 38 clinical pregnancies were achieved (22% per cycle and 40.9% per couple) out of 173 cycles initiated, and 28 births were achieved (16.2% per cycle and 30.1% per couple), producing 34 live births. The rate of multiple pregnancies was 21.4%. Obstetric and neonatal results were similar in the groups of couples studied. At follow-up, no seroconversion was detected in the women or neonates. CONCLUSION Sperm washing and intracytoplasmic sperm injection are shown to be a safe and effective option for reducing the risk of transmission or super infection in serodiscordant or concordant couples who wish to have a child. Pregnancies ob- tained by ART in couples when the male is CVD infected achieve good obstetric and neonatal results.

La consulta de terapia antitrombótica: progresando hacia la Enfermería de Práctica Avanzada.

There is currently around one million people receiving oral anticoagulants in Spain. The drug most used is acenocoumarol, which requires coagulation monitoring to ensure that the patient is within its normal therapeutic range. Patients usually start this treatment in a hospital clinic and, when they are stabilised, they are referred to primary care, where they are followed-up by their community nurses. The usual practice is that nurses are responsible for changes in the dose when the patients are outside the range. This practice is not performed by hospital nurses, despite having sufficient experience and knowledge to adequately manage these types of patients. An Advanced Nursing Practice model has been introduced into the Haematology management unit of the Hospital Universitario Virgen de la Victoria, Málaga. This involves various aspects of attention and care of patients on anticoagulant therapy, and includes adjusting the doses of their treatment following a catalogue of therapeutic and diagnostic ranges.

Complications of laparoscopic gynecologic surgery.

BACKGROUND AND OBJECTIVES To analyze the frequency of complications during laparoscopic gynecologic surgery and identify associated risk factors. METHODS A descriptive observational study was performed between January 2000 and December 2012 and included all gynecologic laparoscopies performed at our center. Variables were recorded for patient characteristics, indication for surgery, length of hospital stay (in days), major and minor complications, and conversions to laparotomy. To identify risk factors and variables associated with complications, crude and adjusted odds ratios were calculated with unconditional logistic regression. RESULTS Of all 2888 laparoscopies included, most were procedures of moderate difficulty (adnexal surgery) (54.2%). The overall frequency of major complications was 1.93%, and that of minor complications was 4.29%. The level of technical difficulty and existence of prior abdominal surgery were associated with a higher risk of major complications and conversions to laparotomy. CONCLUSION Laparoscopic gynecologic surgery is associated with a low frequency of complications but is a procedure that is not without risk. Greater technical difficulty and prior surgery were factors associated with a higher frequency of complications.
