A pragmatic approach for mortality prediction after surgery in infective endocarditis: optimizing and refining EuroSCORE.

OBJECTIVE: To simplify and optimize the ability of EuroSCORE I and II to predict early mortality after surgery for infective endocarditis (IE). METHODS: Multicentre retrospective study (n = 775). Simplified scores, eliminating irrelevant variables, and new specific scores, adding specific IE variables, were created. The performance of the original, recalibrated and specific EuroSCOREs was assessed by Brier score, C-statistic and calibration plot in bootstrap samples. The Net Reclassification Index was quantified. RESULTS: Recalibrated scores including age, previous cardiac surgery, critical preoperative state, New York Heart Association >I, and emergent surgery (EuroSCORE I and II); renal failure and pulmonary hypertension (EuroSCORE I); and urgent surgery (EuroSCORE II) performed better than the original EuroSCOREs (Brier original and recalibrated: EuroSCORE I: 0.1770 and 0.1667; EuroSCORE II: 0.2307 and 0.1680). Performance improved with the addition of fistula, staphylococci and mitral location (EuroSCORE I and II) (Brier specific: EuroSCORE I 0.1587, EuroSCORE II 0.1592). Discrimination improved in specific models (C-statistic original, recalibrated and specific: EuroSCORE I: 0.7340, 0.7471 and 0.7728; EuroSCORE II: 0.7442, 0.7423 and 0.7700). Calibration improved in both EuroSCORE I models (intercept 0.295, slope 0.829 (original); intercept -0.094, slope 0.888 (recalibrated); intercept -0.059, slope 0.925 (specific)) but only in specific EuroSCORE II model (intercept 2.554, slope 1.114 (original); intercept -0.260, slope 0.703 (recalibrated); intercept -0.053, slope 0.930 (specific)). Net Reclassification Index was 5.1% and 20.3% for the specific EuroSCORE I and II. CONCLUSIONS: The use of simplified EuroSCORE I and EuroSCORE II models in IE with the addition of specific variables may lead to simpler and more accurate models.

Anal intraepithelial neoplasia in a sexually transmitted diseases outpatient clinic: correlation with cytological screening.

BACKGROUND: High-grade anal intraepithelial neoplasia (AIN) is currently considered a precursor of anal cancer. The population most susceptible to AIN is men who have sex with men (MSM), especially if they are infected by HIV. OBJECTIVES: We analysed the population diagnosed with AIN and evaluated anal cytology as a method of screening the at-risk population. METHODS: We undertook a retrospective review of patients diagnosed with AIN by means of a surgical biopsy between 2008 and 2010. We analysed the risk factors of the population affected and the degree of agreement with the cytology performed previously. RESULTS: During the study period 41 patients were diagnosed with AIN and seven with anal canal carcinoma in situ; 77% were men, most MSM. A history of receptive anal intercourse was found in 81% of the patients and in 71% there was an association with anogenital warts; 32 patients were HIV-positive, most of them men. Of the patients with anal dysplasia of any type in the cytology, 90% had some grade of AIN or carcinoma in situ in the later biopsy. The degree of agreement between the cytology and the biopsy was 94% in the high-grade dysplasias and 50% in the low-grade dysplasias. CONCLUSIONS: Anal cytology in at-risk populations has a high degree of agreement with the biopsy when performed surgically, though less in low-grade dysplasias, which must always be studied. More studies evaluating the degree of progression of AIN to anal cancer are necessary.

Surgical treatment for infective endocarditis in elderly patients.

OBJECTIVES: We evaluate the clinical, echographic and prognostic characteristics of infective endocarditis (IE) in a large population of elderly patients, and the results of surgical approach. METHODS: Multicentric, prospective, observational cohort study with 961 consecutive left-sided IE: 356 patients aged ≥65 years were compared with 605 younger. Indications for cardiac surgery, potential surgical risk, time and outcome, were compared. RESULTS: Hospital-acquired endocarditis, comorbidity, renal failure and septic shock were more frequent in elderly, but embolisms were less. Intracardiac destruction and ventricular failure were similar in both groups, but significantly fewer elderly patients underwent cardiac surgery (36% vs 51%; p < 0.01), and this group showed a worse outcome (43.2% of mortality vs 27% in younger; p < 0.01), resulting age as an independent predictor of mortality (OR: 1.02 CI95%: 1.01-1.03). Compared with medical treatment, surgery showed lower percentages of mortality compared with medical treatment (23.3% vs 31.3%; p = 0.03) in younger group, but a high mortality was observed with both procedures (47.6% vs 40.3%; p = 0.1) in the elderly. CONCLUSIONS: Although similar percentages of heart failure and intracardiac complications, increasing age is associated with higher mortality in IE. Lower rates of surgical treatment and a worse outcome after operation are common features in elderly patients.

Streptococcus agalactiae left-sided infective endocarditis. Analysis of 27 cases from a multicentric cohort.

SUMMARY OBJECTIVE: To evaluate the current trends in the clinical characteristics and the prognosis of Streptococcus agalactiae infective endocarditis (IE), uncommon disease associated with high mortality. METHODS: Descriptive analysis of 27 cases of a large cohort (961 episodes) of infective endocarditis collected in seven hospitals of Andalusia (Spain) between 1984 and 2008. RESULTS: Native valves were affected in most cases (85. 2%), multiple valves were frequently involved (22.2%). The median age of the patients was 65 (51-76) years (59.3% men), with a comorbidity, according to the Charlson index, of 2.6+/-2.3. The most frequent underlying diseases were diabetes mellitus (25.9%), chronic obstructive pulmonary disease (14.8%), neoplasms (14.8%), urological disorders (11%) and chronic liver disease (11%). Clinical presentation was characterized by rapid worsening (median of 9 (5.7-15) days from onset of symptoms until diagnosis), a high rate of embolisms (37%) and cardiac complications (abscesses, fistulas or valve rupture) - 37% of cases. Surgery was performed in 12 patients (44.4%) and a high mortality (40.7%) was observed. CONCLUSION: S. agalactiae IE is a serious disease with aggressive course and high mortality rate and affects patients with debilitating diseases. We must be alert of the development of complications and consider early valve surgery when it is necessary.

[Epidemiological characteristics and mortality risk factors in patients admitted in hospitals with soft tissue infections. A multicentric STIMG (Soft Tissue Infections Malacitan Group) study results]. / Características clínicas, epidemiológicas y factores asociados a mortalidad en los pacientes hospitalizados por infecciones de piel y partes blandas. Resultados del estudio multicéntrico STIMG.

OBJECTIVES: To describe the characteristics of patients admitted in hospitals with soft tissue infections, and analyse the variables whose died, in order to define risk groups. METHOD: retrospective analysis of medical reports of all patient admitted during 2002 year for soft tissue infections in public malacitans hospitals. We excluded the patient with soft tissue infections associated with burns, surgery, pressure ulcers, and orbit cellulitis. We analysed clinical, biochemical variables and indications for yields and imaging tests, so the empiric antibiotic treatment established and its correlations with practice guidelines. RESULTS: We analysed 391 admissions of 374 patients. Cellulitis was the most frequent diagnosis (69.3%). We did imaging tests in 51.6%. In 94.3% of cases were treated with empirics antibiotics. The most prescribed drug was amoxiciline plus clavulanate (39%). 27 patients died, 40.7% of them for septic cause. All deceased patients had chronic diseases. The only biochemical parameters associated with mortality were serum proteins and albumina (55 +/- 9 g/L vs. 63 +/- 8 g/L; p = 0.0231) and (22 +/- 7 g/L vs. 29 +/- 7 g/L; p = 0.0125) respectively. CONCLUSIONS: Cellullitis are the most frequent soft tissue infections that requires admissions in hospitals. We overuse imaging test and don t follow the practice guidelines recommendations in antibiotic therapy. Primary soft issue infection s mortality is low and it s restricted to people with chronic illness, deep infections and bad nutritional status.

[Manifestations of sarcoidosis in the upper respiratory tract]. / Manifestaciones de la sarcoidosis en el tracto respiratorio superior.

Sarcoidosis is a multisystemic disease having unknown cause, characterized by non-caseating granulomatous inflammation of the organs involved. It predominantly affects the respiratory tract, with preference for the lower tract and less frequently affects the upper respiratory tract (nose, paranasal sinuses and larynx). It manifests non-specifically, with symptoms secondary to the obstruction of the airway. It can be confused with other more common disorders in our setting, such as tuberculosis. We conduct a review, fundamentally focusing on the diagnosis and treatment due to their difficulty.

Health-related quality of life of patients with HIV: impact of sociodemographic, clinical and psychosocial factors.

OBJECTIVES: This study aims to analyse how a wide group of clinical, social, demographic and psychological factors are related to both physical and mental quality of life in HIV + patients. DESIGN: A cross-sectional study was carried out of 320 HIV + patients in antiretroviral treatment who attended infectious diseases units in four hospitals in the region of Andalusia (Spain). METHODS: Health-Related Quality of Life was measured by the MOS-HIV. Included as independent variables were: sociodemographic variables, variables related to antiretroviral therapy, psychosocial variables like social support (Duke-UNC-11) and psychological morbidity (GHQ-28), variables related to main risk behaviours and clinical variables. RESULTS: In the multiple linear regression analysis, a better PHS quality of life was found to be associated with the absence of mental illness, social support, not being an intravenous drug user and using more than one type of non-injectable drug. A better quality of life, in mental terms, was found to be associated with fewer years as a non-intravenous drug user, having social support, absence of mental illness, not being an intravenous drug user taking only one additional pill, not having any difficulty in taking the medication, and being female. CONCLUSIONS: The study of other non-biological factors that may be related to quality of life has been limited practically to social support and the emotional state. This study highlights the importance of these factors independently from the clinical state, as well as the existence of other psychological and behavioural factors that are also related.

[Endophthalmitis and multiple brain abscess in a patient with endocarditis due to Streptococcus agalactiae]. / Endoftalmitis y abscesos cerebrales múltiples en un paciente con endocarditis por Streptococcus agalactiae.

Endogenous endophthalmitis is a rare disease caused by hematogenic germ spread from an internal focus. Infections due to Streptococcus agalactiae are infrequent in adults although new cases had been described recently associated to inmunodepression. We present a patient with endocarditis due to Streptococcus agalactiae, endophthalmitis and multiple brain abscess. We also review the literature.

[Candida albicans spondylodiscitis]. / Espondilodiscitis por Candida albicans.

Infections by Candida sp. have increased notably and cause not only local but also systemic infections. It is rarely mentioned as an etiologic agent of osteomyelitis. Two cases of candidiasic spondylodiscitis are presented with the first being in a 33 year old intravenous drug using male who consulted for mechanical lumbar pain. Spondylodiscitis L2-L3 was observed upon radiological study. Aspiration puncture was carried out and the cultures were negative. Surgical biopsy was performed with spondylodiscitis and an abscess in the spine being observed. C. albicans was isolated in the culture. Pathological study confirmed the diagnosis. Cutaneous and sternocostal involvement was also concommitantly presented. The patient was treated with amphotericin B with a favorable evolution. The second case was in a 35 year old male with burns over 65% of his body due to a laboral accident. Three months after admission the patient presented lumbar pain irradiating to the groin and thigh. Bone destruction of the second lumbar vertebra and an abscess of the right psoas were observed upon CT scan. Puncture biopsy was performed and C. albicans was isolated. Histopathologic study demonstrated osteomyelitis by Candida sp. Treatment with amphotericin B was started. Posteriorly urea and creatinine was raised. Treatment was continued with fluconazole with good therapeutic response.
