Cat scratch disease, whose causative agent is Bartonella henselae, is an anthropozoonosis with a worldwide distribution that causes significant public health problems. Although it is an endemic disease in Spain, the available data are very limited. The aim of our study was to describe cat scratch disease inpatients in the National Health System (NHS) of Spain. This was a retrospective descriptive study using the minimum basic data set (CMBD in Spanish) in patients admitted to hospitals of the NHS between 1997 and 2015 with a diagnosis of cat scratch disease (ICD-9: 078.3). We found 781 hospitalized patients diagnosed with cat scratch disease. The mean age (± SD) was 30.7 ± 25.3 years old. The male/female ratio was 1.1:1. The incidence rate over the study period was 0.93 (95% CI, 0.86-0.99) cases per million person-years. The incidence rate in men was 0.98 cases per million person-years and that in women was 0.88 cases per million person-years. The cases were more frequent from September to January. A total of 652 (83.5%) cases were urgent hospital admissions. The average hospital stay was 8.4 ± 8.9 days. The overall lethality rate of the cohort was 1.3%. We have demonstrated that CSD causes a substantial burden of disease in Spain, affecting both adult and pediatric patients with a stable incidence rate. Our data suggest that CSD is benign and self-limited, with low mortality, and its incidence is possibly underestimated. Finally, there is a need for a common national strategy for data collection, monitoring, and reporting, which would facilitate a more accurate picture and the design of more strategic control measures. Hospital discharge records (HDRs) could be a good database for the epidemiological analysis of the hospital management of CSD.

Schistosomiasis is a helminthic infection and one of the neglected tropical diseases (NTDs). It is caused by blood flukes of the genus Schistosoma. It is an important public health problem, particularly in poverty-stricken areas, especially those within the tropics and subtropics. It is estimated that at least 236 million people worldwide are infected, 90% of them in sub-Saharan Africa, and that this disease causes approximately 300,000 deaths annually. The clinical manifestations are varied and affect practically all organs. There are substantial differences in the clinical presentation, depending on the phase and clinical form of schistosomiasis in which it occurs. Schistosomiasis can remain undiagnosed for a long period of time, with secondary clinical lesion. Here, we review the clinical profile of schistosomiasis. This information may aid in the development of more efficacious treatments and improved disease prognosis.

Background: Mucormycosis is a worldwide angio-invasive fungal infection that is associated with high morbidity and mortality. A few European studies have focused on the epidemiology. Methodology: A retrospective longitudinal descriptive study was performed with inpatients diagnosed with mucormycosis (ICD-9-CM, code 117.7, cases 1997-2015; and ICD-10, code B46, cases 2016-2018; along with length of hospital stay) in Spanish public hospitals between 1 January 1997 and 31 December 2018. Data were obtained from the Minimum Basic Data Set (CMBD in Spanish). Principal findings: A total of 962 patients were recorded; 665 were men. The mean age (±SD) was 55±18.8 years. The annual incidence rate increased from 0.74 to 1.24 cases per million person-years. The lethality rate was 31.3%. Renal failure (41.6%) and hematological malignancy (36.3%) were the main factors involved. Conclusions: Mucormycosis is a rare infectious disease in Spain, but it has had a significantly increased incidence in the last two decades. Being an adult male and having diabetes, neoplasm or renal failure are the main factors associated. High mortality is usually associated mainly with hematological malignancy and renal failure. CMBD studies could be an efficient tool for assessing changes in the epidemiology of mucormycosis.

Brucellosis remains one of the main zoonoses worldwide. Epidemiological data on human brucellosis in Spain are scarce. The objective of this study was to assess the epidemiological characteristics of inpatient brucellosis in Spain between 1997 and 2015. A retrospective longitudinal descriptive study was performed. Data were requested from the Health Information Institute of the Ministry of Health and Equality, which provided us with the Minimum Basic Data Set of patients admitted to the National Health System. We also obtained data published in the System of Obligatory Notifiable Diseases. A total of 5598 cases were registered. The period incidence rate was 0.67 (95% CI 0.65–0.68) cases per 100 000 person-years. We observed a progressive decrease in the number of cases and annual incidence rates. A total of 3187 cases (56.9%) came from urban areas. The group most at risk comprised men around the fifth decade of life. The average (±s.d.) hospital stay was 12.6 days (±13.1). The overall lethality rate of the cohort was 1.5%. The number of inpatients diagnosed with brucellosis decreased exponentially. The group of patients with the highest risk of brucellosis in our study was males under 45 years of age and of urban origin. The lethality rate has reduced to minimum values. It is probable that hospital discharge records could be a good database for the epidemiological analysis of the hospital management of brucellosis and offer a better information collection system than the notifiable diseases system (EDO in Spanish).

Cystic echinococcosis (CE) is a parasitic disease caused by the larval forms of species of the tapeworm Echinococcus. The most common location is the liver. To assess the frequency and clinical characteristics of portal hypertension (PH) and the risk factors for PH development, we performed a retrospective observational study of inpatients diagnosed with hepatic CE and PH from January 1998 to December 2018, at Complejo Asistencial Universitario de Salamanca, Spain. Of 362 patients analyzed with hepatic CE, 15 inpatients (4.1%) had a portal vein diameter ≥ 14 mm, and the mean diameter of the portal vein was 16.9 (standard deviation [SD] ±2.1) mm. Twelve patients were men. The mean age was 59.5 years (SD ± 17.8 years). Four patients had ascites (26.6%), four had collateral circulation (26.6%), 14 had hepatosplenomegaly (93.3%), five had esophageal varices (33.3%), four had hematemesis, and three had jaundice. Other causes of PH included hepatitis B virus (1 patient) and hepatitis C virus (1 patient) infections and alcohol abuse (1 patient). The host variables associated with PH development were male sex (odds ratio, 4.6; 95% confidence interval, 1.1–20.9; P = 0.030) and larger cyst size (10.8 ± 6.3 versus 7.6 ± 4.1; P = 0.004). Hepatic CE is an infrequent cause of PH that usually occurs without indications of liver failure. Larger cyst size and male sex were the main risk factors associated with this complication. Mortality was higher for patients with hepatic CE with PH than for patients with hepatic CE without PH.

Purpose: Complicated urinary tract infections (UTIs) are frequently caused by Enterococcus spp. We aim to define the risk factors involved in UTIs caused by Enterococcus. Determine the overall mortality and predictive risk factors.Methods: A retrospective study was conducted. We compared the results with those of a random sample of patients with complicated UTIs infection caused by Escherichia coli.Results: We found 106 in-patients with UTIs caused by Enterococcus spp., 56 of whom had positive blood cultures. Distribution by species: 83% E. faecalis and 17% E. faecium, with a Charlson comorbidity index of 5.9±2.9. Only male sex with an OR of 2.8 (95%CI 1.2-6.4), nosocomial infection with an OR of 2.8 (95%CI 1.1-7), urinary catheter with an OR of 4.5 (95%CI 1.8-11.3), urinary cancer with an OR of 6.4 (2.1-19.4), and previous antimicrobial treatment with an OR of 4.3 (1.8-10.2) were independent predictors of Enterococcus infection. Overall, in-patient mortality was 16.5%, which was associated with a higher Sequential Organ Failure Assessment (SOFA) score (>4), severe comorbidity such as immunosuppression, malignant hemopathy and nephrostomy, or Enterococcus faecium species and its pattern or resistance to ampicillin or vancomycin (p0.05).Conclusions: Enterococcus spp. is a frequent cause of complicated UTI by a profile of risk factors. High mortality secondary to a severe clinical setting and high comorbidity may be sufficient reasons for implementing empiric treatment of patients at risk, although we did not show a higher survival rate in patients with this treatment strategy.

Background Management options for cystic echinococcosis (CE) remain a serious problem. The main aim of this study was to examine the selection and complications of treatment applied in patients with CE. The second aim was to evaluate the mortality rate and causative factors. Methods A retrospective descriptive study of patients diagnosed with CE between 1998 and 2015 was conducted, according to ICD-9 (code 122·0 to 122·9) criteria in the Complejo Asistencial Universitario of Salamanca, Spain. Results Four-hundred-ninety-one (491) patients were diagnosed with CE disease and the treatment applied in these patients were: 166 (33.8%) patients received only surgery, 176 (35.8%) surgery and drugs, 17 (3.5%) drugs alone, in 131 (26.7%) patients the strategy was 'watch and wait', and only one patient (0.2%) was applied puncture-aspiration-injection-respiration (PAIR). Thus, a total of 342 patients received surgery, either alone (166) or combined with drugs (176), and a total of 193 (39.4%) patients were medically treated, either alone (17) or combined with surgery (176); 123 (63.7%) patients used albendazole alone; and 70 (36.3%) patients used a combination of albendazole and praziquantel. Sixty-five patients (19.0%) had complications after surgery and seven of them (2%) died. Only 15 (7.8%) cases had side effects from anthelmintics. Throughout the study period, 80 (16.3%) patients died, 14 (2.9%) of them due to CE disease. Conclusions Complications of CE are one of the most common causes of mortality in CE patients, with size, location, and number of cysts, and the 'watch and wait' treatment strategy being the main factors associated with mortality.

Background Nutritional problems, anaemia and infectious diseases are the main causes of morbidity and mortality in children and adolescents in tropical and subtropical areas. The main objective of this study was to determine the nutritional status in children from low-income countries who migrated to Spain and the value of the usual biochemistry markers of nutrition in these children, as well as to evaluate the nutritional status associated with imported infectious diseases. Moreover, we evaluated the association between anaemia and nutrition problems. Methods We prospectively evaluated immigrants younger than 18 years of age, from tropical or subtropical areas, who were referred on suspicion of or screening for imported diseases. Detailed medical records and physical and oral examinations were obtained. Blood count and biochemical measures of micronutrients and nutritional biomarkers were performed. We included microbiological methods for diagnosing imported infectious diseases according to the region of origin and clinical setting. Results 373 minors were evaluated, including 250 (67.0%) from sub-Saharan Africa, 67 (18.0%) from North Africa and 56 (15.0%) from Latin America. The mean BMI of the subjects was 19.8±0.2. BMI increased by 0.02 for each month of stay in Spain. Nineteen patients (6.8%) had a nutritional risk of growth problems, and 50 (17.8%) were overweight. The time since arrival was longer in patients who were overweight (p

[EN]Background: Cystic echinococcosis (CE) is a chronic, complex and neglected zoonotic disease. CE occurs worldwide. In humans, it may result in a wide spectrum of clinical manifestations, ranging from asymptomatic infection to fatal disease. Clinical management procedures have evolved over decades without adequate evaluation. Despite advances in surgical techniques and the use of chemotherapy, recurrence remains one of the major problems in the management of hydatid disease. The aim of this study was to determine the frequency of CE recurrence and the risk factors involved in recurrence. Methods: A descriptive longitudinal-retrospective study was designed. We reviewed all patients diagnosed with CE according to ICD-9 (code 122–0 to 122–9) criteria admitted at Complejo Asistencial Universitario de Salamanca, Spain, between January 1998 and December 2015. Results: Among the 217 patients studied, 25 (11.5%) had a hydatid recurrence after curative intention treatment. Median duration of recurrence’s diagnosis was 12.35 years (SD: ±9.31). The likelihood of recurrence was higher [OR = 2.7; 95% CI, 1.1–7.1; p < 0.05] when the cyst was located in organs other than liver and lung, 22.6% (7/31) vs 14.2% (31/217) in the cohort. We detected a chance of recurrence [OR = 2.3; 95% CI, 1.4–6.5; p > 0.05] that was two times higher in those patients treated with a combination of antihelminthic treatments and surgical intervention (20/141, 14.2%) than in patients treated with surgical intervention alone (5/76, 6.6%). Conclusions: Despite advances in diagnosis and therapeutic techniques in hydatid disease, recurrence remains one of the major problems in the management of hydatid disease. The current management and treatment of recurrences is still largely based on expert opinion and moderate-to-poor quality of evidence. Consequently, large prospective and multicenter studies will be needed to provide definitive recommendations for its clinical management.

Background Cystic echinococcosis (CE) is a chronic, complex and neglected zoonotic disease caused by Echinococcus granulosus. Eosinophilia in CE is a classic analytic alteration, although its presentation and importance is very variable and not well established. Methods We performed a retrospective observational study of inpatients diagnosed with CE and eosinophilia from January 1998 to December 2017 in the Complejo Asistencial Universitario de Salamanca in western Spain. Results During the study period, 475 patients with a CE diagnosis underwent a haemogram and 118 (24.8%) patients had eosinophilia. Eighty-two (69.5%) were male and the mean age was 52.1±20.8 y, which was younger in the group with eosinophilia (p Conclusions Eosinophilia can be an indicator for an active search in CE because as much as 40% of cases are asymptomatic at diagnosis. In patients with eosinophilia, management is usually more aggressive and is usually a combined treatment. Our work shows the importance of eosinophilia in our patients with CE and raises unresolved questions.

Objectives: The objective of this study was to assess the epidemiology and burden of Q fever (QF) in Spain. Methods: We designed a retrospective descriptive study using the minimum basic data set in patients admitted to hospitals of the National Health System between 1998 and 2015 with a diagnosis of Q fever (ICD-9: 083.0.). Results: We found 4214 hospitalized patients with a mean age (±SD) of 50.9 ± 19.3 years. The male/female ratio was 3:1. The incidence rate was between 0.41 and 0.65 cases per 100,000 person-years over the 18-year period. The highest incidence of cases was from March to August (p = 0.024). 21.1% patients had pneumonia, 17.5% had liver disease, and only 3.2% had endocarditis. The average hospital stay was 13.8 days (±12.8). A total of 117 (2.8%) patients died. The total mean cost of QF is approximately €154,232,779 (€36,600 ± 139,422 per patient). Conclusions: QF is an important zoonosis in Spain with a stable incidence rate and high cost for hospitalization. Older patients have a more severe clinical picture and higher mortality, which can be decreased with early clinical suspicion.

ResumenIntroduccion La hidatidosis humana es una zoonosis con distribucion cosmopolita. Todavia constituye un importante problema de salud publica en muchas regiones del mundo, incluida la cuenca mediterranea. La situacion epidemiologica actual no es conocida en ciertas regiones de Espana. El objetivo de este trabajo es renovar los datos epidemiologicos de la hidatidosis en pacientes hospitalizados en el sistema publico de salud de Extremadura. Metodos Estudio descriptivo longitudinal y retrospectivo de pacientes hospitalizados con diagnostico de hidatidosis (codigos CIE 122.0-122.9) en centros sanitarios del sistema publico de salud de Extremadura durante el periodo 2003-2012. Resultados Se incluyeron 876 pacientes con diagnostico de hidatidosis; 536 (61%) fueron varones, con una edad media de 65,5 ± 17,8; 19 casos (2,2%) fueron menores de 19 anos: 17 (89,47%) casos entre los anos 2003-2007 versus 2 casos entre 2008-2012 (OR = 7,83; IC 95%: 1,79-34,11; p = 0,001). Un total de 141 (16,0%) eran menores de 45 anos. El diagnostico primario fue mas frecuente en menores de 45 anos y el diagnostico secundario mas frecuente en mayores de 70 anos (p

Background Stevens-Johnson Syndrome (SJS) and Toxic Epidermal Necrolysis (TEN) are serious mucocutaneous reactions. In Spain, the epidemiology and resulting expenses of these diseases are not well established. Methodology Retrospective descriptive study using the Minimum Basic Data Set (CMBD in Spanish) in patients admitted to hospitals of the National Health System between 2010 and 2015 with a diagnosis of SJS and TEN (combination of ICD-9 codes 695.13, 695.14, and 695.15, along with length of hospital stay). Principal findings A total of 1,468 patients were recorded, 773 were men (52.7%). The mean age (± SD) was 52.25 ± 26.15 years. The mean incidence rate for all diagnoses was 5.19 cases per million person-years (2.96 in SJS, 0.31 in SJS/TEN and 1.90 in TEN). 148 patients died (10.1%), 47 due to SJS (5.6%) and 90 (16.7%) due to TEN. The estimated total medical cost of SJS, SJS/TEN, and TEN in Spain was €11.576.456,18, and the average medical cost per patient was €7.885,86 ± €11.686,26, higher medical cost in TEN (€10352.46 ± €16319,93) than in SJS (€6340,05 ± €7078,85) (p

There is still no well-established consensus about the clinical management of hydatidosis. Currently, surgery continues to be the first therapeutic option, although treatment with anti-parasitic drugs is indicated as an adjuvant to surgery to decrease the number of relapses and hydatid cyst size. When surgery is not possible, medical treatment is indicated. Traditionally, albendazole was used in monotherapy as the standard treatment. However, com- bined therapy with albendazole plus praziquantel appears to improve anti-parasitic effectiveness. To date, no safety studies focusing on such combined therapy have been published for the treatment of hydatidosis. In this work, we analyze the adverse effects seen in 57 patients diagnosed with hydatidosis who were treated with praziquantel plus albendazole combined therapy between 2006 and 2010.

Introduction: Abdominal angiostrongyliasis is an infrequently diagnosed disease because it is little known and is usually well tolerated. Methods: We carried out a systematic review with PubMed as a search engine for the MedLine database, and we analysed the clinical, epidemiological and analytical parameters of this disease. Results: In total, reports of 27 case have been found, together with a series of 116 patients, which were later augmented up to 194 patients. In the results, we have observed a predominance of male patients, and Costa Rica, Brazil and the United States as the main countries of origin. Typical symptoms include abdominal pain on the right iliac fossa, with leukocytosis and eosinophilia. Discussion: There are some serological diagnostic methods, although lack of standardization leads to most of the diagnoses being reached via pathology. Surgery is the usual treatment approach. Although there are medical options, this is a controversial subject because of the low number of cases published in the literature, which implies an absence of solid studies.

BACKGROUND In Spain, 12% of the population are immigrants. The impact of immigration in Spain on cystic echinococcosis (CE) is unknown. The aim of this study was to describe the epidemiology of CE in immigrants in western Spain. METHODS First, a retrospective descriptive study of patients diagnosed with CE in the University Hospital of Salamanca (CAUSA) between January 1998 and December 2014 was designed. Second, we studied the seroprevalence of CE in sera from foreigners who received treatment in the Tropical Medicine Unit. RESULTS A total of 550 patients with new CE-related diagnoses were registered; of these, 16 (2.9%) were immigrants, of whom 10 (63%) were male. The age (mean±SD) was 34.6±12.8 years. The incidence rate of CE in immigrants was 8.76 cases per 105 person-years. Eight (50%) cases presented asymptomatically. Seroprevalence of CE in foreign patients was 2.3%. It was higher in North African population (4.2%), followed by sub-Saharan (2.4%) and Latin American (1.8%) (p=0.592) populations. The seroprevalence was higher in those who arrived recently (

Immigrants to Spain are mainly from low- and middle-income countries, and around 20% are children. Absolute eosinophilia is defined as0.45×10To describe the importance of relative eosinophilia in a cohort of immigrant children (18 years) from sub-Saharan Africa, North Africa and Latin America.176 immigrant children without absolute eosinophilia were prospectively evaluated.25 of them (14.2%) had relative eosinophilia. 10 patients with relative eosinophilia had no diagnosis. 15 with relative eosinophilia (60%) were diagnosed with a parasitic disease, 7 (46.7%) of whom had only one parasite, while co-infection accounted for 8 of the 15 cases (53.3%). Of the parasitic infections, the most frequent causes of relative eosinophilia were filariasis spp. (7/15, 46.7%), strongyloides spp. (5/15, 33.3%), schistosoma spp. (4/15, 26.6%) and Ascaris lumbricoides (2/15, 13.3%).The findings suggest that relative eosinophilia is frequently associated with helminthic infection in immigrant children from tropical and sub-tropical areas, so a thorough parasitological study is highly advisable in this group of patients.

La enfermedad de Ormond (EO) es una enfermedad infrecuente con una incidencia aproximada de 1/1.000.000 personas-ano. La etiologia en la mayoria de los casos es desconocida, y en la EO secundaria se han implicado multiples procesos patogenicos. La EO se caracteriza por la presencia de una masa fibroinflamatoria retroperitoneal con tres formas clinicas diferentes: i) fibrosis retroperitoneal; ii) fibrosis perianeurismatica retroperitoneal, y iii) inflamacion de los aneurismas de la aorta abdominal. El manejo clasico se basa en el tratamiento quirurgico y puede asociarse a esteroides. En estos ultimos anos se han empleado otros inmunosupresores sin resultados bien establecidos. Presentamos cinco casos acontecidos en el Hospital Clinico Universitario de Salamanca durante el periodo 2000�2008. Destacamos la falta de estudios para establecer guias de practica clinica que faciliten el manejo y mejoren el pronostico

Resumen El cancer de pulmon es una de las neoplasias mas frecuentes. La clinica se debe al propio tumor, a su extension o a los sindromes paraneoplasicos asociados. A pesar de que las metastasis de localizacion biliopancreatica son frecuentes, la afectacion en esta region como inicio de una neoplasia pulmonar, tanto en la forma de pancreatitis como en la de ictericia obstructiva, es rara. Exponemos nuestra experiencia clinica mediante la presentacion de 2 casos de pancreatitis aguda y uno de ictericia obstructiva como forma de inicio de una neoplasia pulmonar avanzada junto con una breve revision bibliografica, que confirma la ausencia de protocolos de actuacion en esta situacion.

Echinococcosis is a zoonotic infection with a worldwide distribution, and is still an important health problem in many areas of the world, including the Mediterranean basin. At present the epidemiological situation is unclear in certain regions of Spain. The aim of this study was to update the epidemiological situation in Extremadura through an analysis of hospitalised patients in the public health system diagnosed with hydatid disease.A longitudinal retrospective study was conducted between 2003 and 2012 on hospitalised patients with a diagnosis of hydatidosis (ICD 122.0-122.9) in hospitals of the public health service of Extremadura.During the period of study, 876 patients were diagnosed with hydatid disease. Of these 536 (61%) of cases were male, with a mean age of 65.53±17.8 years. More importantly, 19 (2.2%) of patients were 19 years old, with 17 cases between 2003-2007 versus 2 cases between 2008-2012 (OR=7.83; 95%CI: 1.79-34.11; P=.001). A total of 141 (16.0%) were younger than 45 years. The primary diagnosis was most frequently reported in the younger population45 years, whereas the secondary diagnosis was usually found in the elderly population70 years (P.05). The incidence rate of hydatid disease obtained from Hospital Discharge Records (HDRs) was significantly higher compared to the incidence that was declared in the Notifiable Disease System of Extremadura (8.02 cases per 10(5) person-years vs. 1.88 cases per 10(5) person-years [P.05]).In Extremadura hydatid disease is still frequent. With a clear decrease in the number of paediatric cases. The number of cases obtained from HDRs regarding Notification System Diseases Extremadura suggests the need for modifications to improve surveillance and control of hydatid disease.

SUMMARYCystic echinococcosis (CE) remains an important health problem in many areas of the world, including the Mediterranean region. We performed a retrospective study of cases reported from 1998 to 2012 in order to review and update the epidemiology of this disease in a highly endemic area situated in western Spain. A total of 471 patients were diagnosed with hydatid disease. Of these cases, 55·8% were male, with an average age of 62·3 ± 19·5 years. More importantly, 1·5% of patients were children, and 20·5% were aged β = −0·4357, P < 0·001). CE incidence has diminished in recent years, although active transmission remains in paediatric cases. Additionally, CE incidence remains high in our region despite public health plans for its control. The documented incidence of CE disease clearly underestimates the real numbers.

Immigrants from undeveloped countries are a growing problem in Europe. Spain has become a frequent destination for immigrants (20% of whom are children) because of its geographic location and its historic and cultural links with Africa and Latin America. Eosinophilia is frequent in adult immigrants, travelers and expatriates coming from tropical areas. However, there are few studies that focus on the incidence and causes of tropical eosinophilia and hyper-IgE in immigrant children. We evaluated, prospectively, the prevalence and causes of eosinophilia and hyper-immunoglobulin E (IgE) in 362 immigrant children coming from Sub-Saharan Africa, Northern Africa and Latin America to Salamanca, Spain, between January 2007 and December 2011. Absolute eosinophilia and hyper-IgE were present in 22.9% and 56.8% of the analyzed children, respectively. The most frequent causes of absolute eosinophilia were filariasis (52.6%), strongyloidiasis (46.8%) and schistosomiasis (28.9%). Filariasis (41.9%), strongyloidiasis (29.6%) and schistosomiasis (22.2%) were the most frequent causes of increased levels of IgE. The area under the ROC curve showed similar values between eosinophil count and IgE levels in the diagnosis of helminthiasis (69% [95% confidence interval (CI) 63%–74%] vs 67% [95% CI 60%–72%], P = 0.24). Eosinophilia and hyper-IgE have a high value as biomarkers of helminthiasis in children coming from tropical and subtropical areas.

Relative eosinophilia (defined as an eosinophil percentage >5% but an eosinophil count

Fever of unknown origin (FUO) is an entity caused by more than 200 diseases. Haematologic neoplasms are the most common malignant cause of FUO. Fever as a first symptom of colonic tumour pathology, both benign and malignant, is a rare form of presentation. Our work is a descriptive study of a series of 23 patients with colonic tumoral pathology who presented with fever of unknown origin. The mean age was 67.6 years; 56.5% of patients were men and 43.5% were women. Primary malignant neoplasia was the most common diagnosis. Blood cultures were positive in 45% of the samples. Coagulase-negative staphylococci were the most common cause of bacteraemia. Nine of 10 faecal occult blood tests performed were positive. Fever secondary to colon neoplasms, both benign and malignant, usually presents with a bacteraemic pattern, with positive results for blood-culture tests in a high percentage of cases.

Objectives Septic thrombophlebitis of the portal vein or its branches, most often secondary to intra-abdominal infection is known as pylephlebitis. The frequency and the prognosis of this complication are unknown. The aim of this study was to determine the global and relative incidence of the most frequent intra-abdominal infections and the real prognosis of this disease. Methods An observational retrospective study was conducted in a tertiary care hospital (University Hospital of Salamanca, Spain) from January 1999 to December 2008. Results A total of 7796 patients with intra-abdominal infection were evaluated, of whom 13 (0.6%) had been diagnosed with pylephlebitis. Diverticulitis was the most frequent underlying process, followed by biliary infection. Early mortality was 23%. Survivors had no recurrences, but one of them developed portal cavernomatosis. Conclusions Pylephlebitis is a rare complication of intra-abdominal infection, with a high early mortality, but with a good prognosis for survivors.

Tularemia is a worldwide zoonosis caused by Francisella tularensis. The most frequent forms of tularemia are ulceroglandular, followed by typhoidal forms, glandular, and oculoglandular. Respiratory involvement is an uncommon presentation. Cutaneous lesions secondary to respiratory infections occur in 30% of cases. We present a case of tularemia with cavitary pneumonia and skin lesions.

6 páginas, 2 figuras, 2 tablas., Cystic echinococcosis (CE) remains an important health problem in many regions of the world, both where no control measures have been implemented, and where control programs have been incompletely successful with ensuing re-emergence of the disease. In Spain, official data on CE show an increase in the proportion of intermediate hosts with CE during the last few years, and autochthonous pediatric patients have been reported, a sign of active local transmission of disease. A similar picture emerges from data reported to the European Food Safety Authority by other European countries. Nevertheless, several crucial aspects related to CE that would help better understand and control the disease have not been tackled appropriately, in particular the emergence of infection in specific geographical areas. In this respect, while some data are missing, other data are conflicting because they come from different databases. We review the current situation of CE in Spain compared with areas in which similar problems in the CE field exist, and offer recommendations on how to overcome those limitations. Specifically, we believe that the introduction of national registries for CE with online data entry, following the example set by the European Registry for Alveolar Echinococcosis, would help streamline data collection on CE by eliminating the need for evaluating and integrating data from multiple regions, by avoiding duplication of data from patients who access several different health facilities over time, and by providing much needed clinical and epidemiological data that are currently accessible only to clinicians.

Lung cancer is one of the most frequent neoplasms. The symptoms are due to the cancer itself, its extension, and associated paraneoplastic syndromes. Although biliopancreatic metastases are common, biliopancreatic involvement as the initial symptom of lung cancer--whether as pancreatitis or obstructive jaundice--is rare. We describe our clinical experience, reporting two patients with acute pancreatitis and one patient with obstructive jaundice as the clinical presentation of advanced lung cancer. We also provide a brief review that highlights the absence of guidelines in this situation.

a b s t r a c t Ormond's disease (OD) is an uncommon process with an annual incidence nearing 1 per million inhabitants. The etiology in most of the cases is unknown and several pathogenic mechanisms are implicated in secondary OD. Ormond disease is characterized by a fibrotic and inflammatory mass with three different clinical features: 1) retroperitoneal fibrosis, 2) perianeurysmatic retroperitoneal fibrosis and 3) inflammatory abdominal aortic aneurysms. Classic management is based on surgical treatment associated or not with steroids. Immunosuppressive agents have been used in the last years with unclear results. We report five cases from the University Hospital of Salamanca occurring during 2000-2008. We highlight the lack of trials designed to establish clinical guidelines for the treatment of the disease and improvement of outcome.

Varon de 71 anos, ex fumador de 20 paquetes/ano. No referia viajes al extranjero, contactos con animales ni otros antecedentes de interes. La clinica se inicio con un cuadro de debilidad muscular en las cinturas escapular y pelviana. Con el diagnostico de polimialgia reumatica, se pauto tratamiento con 0,3mg/kg/dia de metilprednisolona. El paciente acudio 6 semanas despues por fiebre, disnea, tos no productiva y dolor pleuritico costal. Esto se acompanaba de artralgias simetricas en las munecas y los tobillos. En la exploracion destaco mal estado general y fiebre de 38,5 1C, taquicardia de 110 latidos por minuto, taquipnea de 30 respiraciones por minuto y estertores crepitantes secos bilaterales. Presentaba minima inflamacion de ambas munecas y fenomeno de Raynaud en las palmas (fig. 1). La analitica mostro recuento de leucocitos de 11.280 10/ml, de neutrofilos de 8.800 10/ml, lactato-deshidrogenasa de 1.160U/l, aspartato-aminotransferasa de 93U/l, alanino-aminotransferasa de 110U/l, fosfatasa alcalina de 100U/l, gamma-glutamiltransferasa de 135U/l y velocidad de sedimentacion globular de 79mm/1.h. Las enzimas creatin-cinasa y creatin-cinasa isoenzima MB, troponina I, mioglobina y aldolasa se encontraban dentro de los limites normales, asi como la hemostasia. La gasometria era compatible con insuficiencia respiratoria parcial. En la radiografia de torax (fig. 2) se aprecio un patron intersticial bilateral difuso de predominio en el pulmon derecho. El paciente ingreso con el diagnostico inicial de neumopatia intersticial de posible causa infecciosa. Se pauto ceftriaxona y doxiciclina, con mala evolucion inicial, por lo que se solicito broncoscopia y tomografia axial computarizada de alta resolucion. Los cultivos repetidos de sangre y esputo para bacterias, micobacterias y hongos fueron negativos, asi como las serologias de bacterias atipicas. El lavado broncoalveolar con aspirado bronquial mostro componente inflamatorio neutrofilico. La tomografia axial computarizada de alta resolucion fue informada como enfermedad intersticial difusa de predominio periferico en relacion con probable neumonia organizada criptogenetica (NOC) (fig. 3). Se recibieron los autoanticuerpos, que aclararon el diagnostico: anticuerpos anti-Jo1 de 376U/ml [N: 0–80], antinucleares 1/320, factor reumatoide 41,8U/ml. Iniciamos tratamiento con metilprednisolona (1mg/kg/dia). El estudio electromiografico fue normal y la espirometria manifesto www.reumatologiaclinica.org

BackgroundCystic hydatid disease is still an important health problem in European Mediterranean areas. In spite of being traditionally considered as a "benign" pathology, cystic echinococcosis is an important cause of morbidity in these areas. Nevertheless, there are few analyses of mortality attributed to human hydatidosis.ObjectiveTo describe the epidemiology, the mortality rate and the causes of mortality due to E. granulosus infection in an endemic area.MethodologyA retrospective study followed up over a period of 14 years (1998-2011).Principal findingsOf the 567 patients diagnosed with hydatid disease over the period 1998-2011, eleven deaths directly related to hydatid disease complications were recorded. Ten patients (90.9%) died due to infectious complications and the remaining one (9.1%) died due to mechanical complications after a massive hemoptysis. We registered a case fatality rate of 1.94% and a mortality rate of 3.1 per 100.000 inhabitants.ConclusionsHydatidosis is still a frequent parasitic disease that causes a considerable mortality. The main causes of mortality in patients with hydatidosis are complications related to the rupture of CE cysts with supurative collangitis. Therefore, an expectant management can be dangerous and it must be only employed in well-selected patients.
