Clinic-pathological agreement in the diagnosis of conjunctival tumours: Analysis of 195 cases.

PURPOSE: The present study aims to assess the agreement between clinical and pathological diagnosis in conjunctival tumours in a specialist ocular oncology unit. METHODS: retrospective study of consecutive patients with conjunctival tumours diagnosed at the Ocular Oncology Unit of the University Hospital of Valladolid was performed from 1992 to 2017. Tumours were classified according to their origin (epithelial, melanocytic, lymphoid and others) and degree of malignancy (benign, premalignant, malignant). A biopsy was performed in cases of symptomatic or growing lesions. Cohen´s kappa (κ) statistics was used as an indicator of agreement between clinical and pathological diagnosis. RESULTS: Of 462 consecutive patients, a biopsy was required in 195 (42.2%). The agreement with the pathological diagnosis was successful in 154 (79.0%) cases. Analysis according to the grade of malignancy showed the lowest rate of agreement among benign (n = 83; 91.6%) and premalignant (n = 62; 90.3%) lesions, with a total agreement in malignant lesions (n = 50; 100%); the Cohen´s kappa coefficient (κ) was 0.90. The highest rates of concordance were found in epithelial, melanocytic and soft tissue lesions with κ values of 1, 0.8 and 1 respectively. The worst rate of concordance was found in lymphoid lesions with a κ value of 0.3. CONCLUSION: Most of the conjunctival tumours were correctly identified clinically; benign and malignant lesions showed the highest rate of accuracy; however, premalignant tumours can hide micro-invasive diseases that can go unnoticed on clinical examination. The biopsy is essential for accurate diagnosis and treatment.

Endourological treatment for lumbar ureteral stones. What are the benefits of flexible ureterorenoscopy?

INTRODUCTION AND OBJECTIVES: Currently, there are no established criteria regarding treatment for lumbar ureteral stones. The objective of this work is to present our results in the endourological treatment of this pathology, analyzing the variables associated with the use of the flexible ureterorenoscope. MATERIAL AND METHODS: Retrospective review of 103 patients who underwent retrograde URS with semi-rigid or flexible ureterorenoscope. Proximal location: L2-L3. Medial location: L4-L5. Semirigid URS was the initial treatment, with conversion to flexible URS when it was required to complete the procedure. Success was defined as absence of residual fragments (6 weeks). Demographic, surgical, immediate postoperative variables, and those related to the stone, were analyzed. Their correlation with the use of the flexible ureterorenoscope was evaluated. RESULTS: Mean age: 57.2 years (SD 15.6); there were 73 men (70.9%). Stone size: 8 mm (range 4-30; IQR 4.5). Proximal location: 58 (56.3%). Previous JJ: 44.7%. Previous nephrostomy: 10.7%. Semirigid URS with conversion to flexible URS: 51 (49.5%). Impacted stones: 28.2%. Intraoperative complications: 2 (1.9%). Postoperative JJ: 84.5%. Immediate postoperative complications: 23 (22.3%) (Clavien-Dindo I-II: 91.3%). Postoperative ureteral stricture: 5.8%. Success: 88.4%. Residual fragments: 12 (11.7%). Spontaneous passage: 6 (50%). Greater performance of flexible URS in proximal ureteral stones (p = 0.001) of more than 11 mm (p = 0.02) in univariate analysis, and in proximal stones [OR 3.5; 1.5-8.1; p = 0.004] in multivariate analysis. CONCLUSIONS: Endourological treatment obtained a high success rate in our sample. Size greater than 11 mm and proximal ureteral location in univariate and multivariate analysis, respectively, behaved as predictors of flexible URS.

Undernutrition measured by the Mini Nutritional Assessment (MNA) test and related risk factors in older adults under hospital emergency care.

OBJECTIVES: In developed countries, undernutrition affects mostly older adults, worsens with hospitalization, and affects immune response, with higher rates of infection and delayed wound healing-which leads to an increase in hospital stay and health costs. The aim of this study was to assess the prevalence of undernutrition and related risk factors in a sample of older adults who presented at the emergency room (ER) of a university hospital in Spain. METHODS: This was a cross-sectional study of 288 patients ≥70 y of age who were seen at the emergency department at the University Hospital of Valladolid. Variables of nutritional evaluation, including a Mini Nutritional Assessment Test, sociodemographic factors, comorbidities, chronic treatments, frequency of visits to the ER, and destination after hospital discharge were collected. RESULTS: The percentage of undernutrition was 14.9% and the risk for undernutrition was 54.5%. Most patients were able to independently conduct basic activities of daily living (BADLs), lived at home, resided in an urban environment, and had autonomous mobility. The mean body mass index (BMI) was 26.14 ± 4.52 kg/m2. Patients who were dependent on others for BADLs; institutionalized or bedridden; and with hematologic disease, chronic depressive syndrome, polymedication, low hemoglobin or low hematocrit, and hypochromia were associated with a higher prevalence of undernutrition. In the multivariate analysis, for each unit of increase in BMI, patients had 12% lower risk for developing undernutrition, and for each unit of increase in the frequency of ER visits, patients had a 41% higher risk for developing undernutrition. CONCLUSIONS: Older adults who presented to the ER had a high percentage of undernutrition, which is related to sociodemographic factors, comorbidities, polymedication, and biochemical factors. We also found a direct association between the frequency of ER visits and undernutrition, in addition to an inverse relationship with BMI. Detecting undernutrition in an ER may improve health and reduce related complications in older adults.

Impact of empirical treatment with antifungal agents on survival of patients with candidemia.

OBJECTIVE: The objective of this study was to evaluate the impact of echinocandins and fluconazole) on mortality 7 and 30 days after candidemia onset and overall in-hospital mortality), in patients with candidemia at a Spanish tertiary hospital. METHODS: A retrospective study was conducted that enrolled all non-neutropenic adult patients diagnosed with candidemia at Hospital Clínico Universitario de Valladolid between 2007 and 2016. A total of 179 patients were evaluated, they were divided into two sub-groups: surviving patients (n = 92) and non-surviving patients (n = 87). RESULTS: The 7-day mortality was 25,1% (45), 30-day mortality was 46,9% (84), and overall in-hospital mortality was 48,6% (87). 40.8% of patients received no antifungal treatment (43.8% of surviving patients and 37.8% of non-surviving patients; p=0.15). A total of 106 (59.2%) patients were treated, of which 90 patients (50.3%) received empiric treatment. 19.6% and 47.8% of surviving patients were treated with echinocandins and fluconazole, respectively. By contrast, of non-surviving patients, 31.0% were treated with echinocandins and 47.1% received fluconazole. Survival for the first 7 days was significantly higher in treated with antifungal agents (log-rank = 0.029), however, there were not significant differences in 30-day survival. Factors linked to a significant increase in overall in-hospital mortality were age (OR 1.040), septic shock (OR 2.694) and need for mechanical ventilation > 48 h (OR 2.812). CONCLUSIONS: Patients who received antifungal treatment, regardless of whether they received fluconazole or echinocandins, had a significantly lower mortality rate after 7 days than untreated patients, although no significant differences in 30-day mortality were seen.

Intraocular metastasis: comparison of clinical presentation with a known and unknown primary tumour. / Metástasis intraoculares: comparación entre las formas de presentación clínica con tumor primario conocido y desconocido.

OBJECTIVE: The purpose of the present study is to review the frequency of intraocular metastases as first presentation of systemic disease, and to identify clinical and tumour characteristics. METHODS: Retrospective study of consecutive cases diagnosed of intraocular metástasis at a referral intraocular tumours unit between 1993 and 2014. General, epidemiological and ophthalmological characteristics were recorded. RESULTS: A total of 21 patients, with a mean age 62.7 years (31-89) were diagnosed with intraocular metástasis between 1993 and 2014. Both eyes were affected in 4 cases. Location was choroid in 20 cases. The intraocular tumour was the first manifestation of the systemic disease in 13 patients (61.9%). Primary tumour was breast in 47.6% and lung in 23.8%. Diagnosis of the primary tumour was performed by systemic studies, and only 1 patient required intraocular biopsy. Regarding the treatment, the majority of cases were controlled with systemic therapy, with 4 cases requiring additional external beam radiotherapy, and only one enucleation. No clinical differences were found between the cases with known and unknown systemic neoplasia, except in exudative retinal detachment, which was more frequent in the second group. CONCLUSIONS: Although intraocular metastases are the most frequent intraocular tumour, they are not a frequent cause of consultation. In more than half of the cases it is the first presentation of unknown systemic neoplasia as a solitary non-pigmented intraocular mass. Early diagnosis is crucial to establish the appropriate treatment, preserve visual function, and improve the prognosis of the patient.

Antifungal treatment with echinocandins: a 10-year clinical experience.

OBJECTIVE: The number of studies evaluating the use of echinocandins, whether or not its indication meets international guidelines, in clinical practice is limited. The objective of the present study was to determine the use of echinocandins in a tertiary Spanish hospital in 10 years of clinical practice, and to evaluate its impact on prognosis. METHODS: This retrospective study involved adult nonneutropenic ill patients with suspicion of fungal invasion who started treatment with echinocandins between 2006 and 2015. RESULTS: The number of patients treated with echinocandins was 153, and candidemia was detected thereafter in 25.5%. Factors associated with in-hospital mortality in patients receiving echinocandins were: sex male, septic shock, Charlson comorbidity index, and total stay at the hospital. In-hospital mortality after 7, 30 and 90 days was 13.7%, 24.8%, and 56.8%, respectively. From patients receiving echinocandins, 98 did no show multifocal colonization, 50 had Candida score <2.5, and 49 did not meet Ostrosky-Zeichner prediction rule. A total of 19 patients did not show any of these 3 potential risk factors for candidemia. CONCLUSIONS: The use of echinocandins in 10 years of clinical practice in our tertiary hospital has been performed according to international guidelines; however, candidemia was only diagnosed thereafter in only 25.5% of cases. Furthermore, according to our results, the adequate use of echinocandins seems not to be associated with reduced mortality rates. Further studies, involving a large cohort of patients and more hospitals, are required to corroborate these results.

Impact of the implementation of a Sepsis Code hospital protocol in antibiotic prescription and clinical outcomes in an intensive care unit. / Impacto de la implantación de un Código Sepsis intrahospitalario en la prescripción de antibióticos y los resultados clínicos en una unidad de cuidados intensivos.

INTRODUCTION: A study was performed to analyze the impact of an in-hospital Sepsis Code (SC) program on use of antibiotic and clinical outcomes. DESIGN: Quasi-experimental observational retrospective study. SETTING: Polyvalent 11 beds ICU belonging to a tertiary Universitary hospital. PATIENTS: Patients admitted consecutively to the ICU with diagnosis of severe sepsis or septic shock. INTERVENTIONS: A post intervention group (POST-SC) (September 2012-August 2013) was compared with a historical group (PRE-SC) used as control (January-December 2010). VARIABLES: Antibiotic treatment, therapeutic antibiotic strategy, mortality and length of stay. Antibiotic consumption was expressed as defined daily doses (DDD)/ 100 stays. RESULTS: 42 patients with SS/SS in POST-SC group and 50 patients in PRE-SC group were consecutively recluted and further analyzed. Total antibiotic consumption (DDD) was similar in both groups. Rate of de-escalation therapy was significantly higher in POST-SC group (75% vs 30,8%, p<0,005) while prescription of restricted antibiotics was significantly lower (74% vs 52%, p=0,031). Finally POST-SC patients showed a significantly decrease in hospital and 28 days mortality rates [23% vs 44%, (p=0,035) and 31% vs 56% (p=0,014) respectively] as well as a reduction in ICU length of stay compared to PRE-SC cohort (5 days vs 10,5 days, p=0,05). CONCLUSION: The implementation of a Sepsis Code-hospital protocol is associated to an improvement in the management of antibiotic therapy with a significant increase in de-escalation therapy and lesser utilization of restricted use antibiotics, as well as a significant reduction in mortality, and a tendency towards shorter ICU length stay.

Design of a New Risk Score in Critical Limb Ischaemia: The ERICVA Model.

OBJECTIVES: It is difficult to establish which patients suffering from critical lower limb ischaemia will benefit from revascularization. Risk scores can provide objectivity in decision making. The aim was to design a new risk score (ERICVA) and compare its predictive power with the PREVENT III and Finnvasc scores. METHODS: An observational retrospective study of patients who underwent revascularization (open or endovascular) in Valladolid's University Hospital between 2005 and 2010 was designed. The sample was divided into two subgroups (development and validation subsamples). After univariate analysis followed by a multivariate Cox regression, a number of variables associated with death and/or major amputation were selected, creating a weighed score called ERICVA, and a simplified version of it. The area under the curve (AUC) of receiver operating characteristic (ROC) curve analysis was performed and the AUC of these two scores were additionally compared with the AUC of the PREVENT III and Finnvasc scales. RESULTS: Six hundred and seventy two cases with an average surveillance of 778 days were included in the study. Amputation free survival (AFS) was 84.8% at 30 days and 63.1% at 1 year. Variables associated with death and/or major amputation in the Cox regression were cerebrovascular disease, prior contralateral major amputation, diabetes mellitus, dialysis, chronic obstructive pulmonary disease, cancer, haematocrit less than 30%, neutrophil/lymphocyte ratio exceeding 5, absence of arterial Doppler signal at the ankle, emergency admission, and Rutherford stage 6; these variables were used for the ERICVA and simplified ERICVA score designs. Scores were applied to both subsamples; in the development sample the AUC of ERICVA and simplified ERICVA was significantly higher than the PREVENT III (p = .008 and p = .045) and Finnvasc (p < .0001 and p = .0013) scores; in the validation sample the AUC of ERICVA and simplified ERICVA were significantly higher than Finnvasc score (p = .0323 and p = .0017). CONCLUSIONS: The ERICVA model has a good predictive capacity for death and/or major amputation in the clinical setting, and is better than the PREVENT III and Finnvasc scores.

[Results of surgical treatment of carpal scaphoid pseudarthrosis using the Fisk-Fernández technique]. / Resultados del tratamiento quirúrgico de la seudoartrosis de escafoides carpiano con la técnica de Fisk-Fernández.

AIM: The aim of the study was to evaluate the clinical and radiological results obtained in the treatment of carpal scaphoid non-union treated at the University Hospital of Valladolid using the Fisk Fernandez technique. MATERIAL AND METHODS: A review was performed on 43 cases of surgically treated non-union using Fisk Fernandez technique with a minimum of 6 months follow-up. The time until surgery, previous treatment, the mechanism of injury, type of non-union, and the existence of radio-carpal arthrosis were evaluated. A subjective evaluation was performed using the "Scaphoid Score" and the DASH, plus an objective assessment with the modified Green & O'Brien, together with the measurement of the intra-scaphoid, radioulnar, scapholunate angles, and carpal height. RESULTS: The median time to healing in the series was between 16 to 24 weeks, except in 3 patients who failed to heal and required salvage surgery. There was a statistically significant variation between the preoperative and postoperative angles and carpal height measured in the X-rays. DISCUSSION: There are different osteosynthesis techniques and materials for the treatment of non-union. The evaluation of results performed using objective and subjective scales showed variable results between studies. Different techniques are aimed at preventing the progression of the disease. CONCLUSION: The Fisk Fernandez technique enables the deformity of the scaphoid to be corrected by wedge grafting and internal fixation with Kirschner wires or screws.

[Impact of colorectal cancer screening using an immunological assay in a basic urban health area]. / Impacto del cribado de cáncer colorrectal mediante análisis inmunológico en una zona básica de salud urbana.

OBJECTIVE: To describe the results of implementing a pilot screening program, in the Castilla y León, for colorectal cancer (CRC) with the faecal occult blood test (iFOBT) using a quantitative immunological latex agglutination assay. METHODS: The study population included 4930 persons between 50-69 years from the Basic Health Area of Medina del Campo. Colonoscopy was performed on those who had a positive iFOBT. The rates of participation were calculated, positivity, acceptance of colonoscopy, detection of lesions, percentages and predictive positive value (PPV) of the test. RESULTS: A total of 2241 (46.33%) people took part. There were 138 (6.15%) positive iFOBT. The rate acceptance of the colonoscopy was 99.27%. CRC was detected in 12 patients (91.66% in early stages), a high risk adenoma (HRA) in 42, and a low risk adenoma (LRA) in 34. The rates of detection were for CRCwas 5.35‰, 18.74‰ for HRA, 15.17‰ for LRA, and 39.26‰ for all kinds of adenoma. The PPV was 8.69% for CCR, 30.43% for HRA and 24.63% for LRA. CONCLUSIONS: The CRC screening program is feasible in our context. The iFOBT indicators are superior to those of other studies performed using the classic test. The high rates of detection of CRC, and all kinds of adenoma would be enough to justify the study. These together with the diagnosis of CRC in the early stages could lead to a reduction of the mortality.

A differential centrifugation protocol and validation criterion for enhancing mass spectrometry (MALDI-TOF) results in microbial identification using blood culture growth bottles.

Matrix-assisted laser desorption/ionization-time-of-flight mass spectrometry (MALDI-TOF) is a widely used tool in clinical microbiology for rapidly identifying microorganisms. This technique can be applied directly on positive blood cultures without the need for its culturing, thereby, reducing the time required for microbiological diagnosis. The present study proposes an innovative identification protocol applied to positive blood culture bottles using MALDI-TOF. We have processed 100 positive blood culture bottles, of which 36 of 37 Gram-negative bacteria (97.3 %) were correctly identified directly with 100 % of Enterobacteriaceae and other Gram-negative rods and 87.5 % of non-fermenting Gram-negative rods. We also correctly identified directly 62 of 63 of Gram-positive bacteria (98.4 %) with 100 % of Streptococcus, Enterococcus, and Gram-positive bacilli and 98 % of Staphylococcus. Applying the differential centrifugation protocol at the moment the automatic blood culture incubation system gives a positive reading together with the proposed validation criterion offers 98 % sensitivity (95 % confidence interval: 95.2-100 %). The MALDI-TOF system, thus, provides a rapid and reliable system for identifying microorganisms from blood culture growth bottles.

[Study of the anthropometric and nutritional characteristics of adolescents in the city of Valladolid]. / Estudio de las características antropométricas y nutricionales de los adolescentes del núcleo urbano de Valladolid.

OBJECTIVES: A description of the anthropometric characteristics of a sample of adolescents from Valladolid and the analysis of dietary intake of the population. MATERIALS AND METHODS: Observational study of descriptive cross-field of a sample of 557 adolescents (14-18 years) by probabilistic sampling from 6 public and private, in different districts of Valladolid. We carried out a food frequency questionnaire with anthropometric measurements. The classification of individuals was by calculating the Z-score of body mass index (BMI), the Cole´s cutoff points for BMI and criteria of the International Diabetes Federation (IDF). Nutritional analysis: probabilistic approach and the nutrient adequacy ratio. RESULTS: Excess weight is similar in both sexes (17%), but there is a 15.2% prevalence of underweight among the women studied, compared to 4.5% in males (p<0.005). 1.3% risk of having metabolic syndrome. Energy consumption is distributed: 30-32% fat, 45% carbohydrates and 16-17% protein. The nutritional deficiency likely reflects consumption in iodine, zinc, vitamins A and E. CONCLUSIONS: The prevalence of obesity is close to that of other series, but the prevalence of overweight is lower. It is very important percentage of women with a BMI below normal for their age and sex. There is an excess of protein intake of saturated fat and cholesterol, with a deficit in the consumption of carbohydrates, iodine, zinc and vitamins A and E.

[Study on the immediate care clinics of the Internal Medicine Department (University Clinic Hospital of Valladolid)]. / Evaluación de las consultas de atención inmediata en Medicina Interna (Hospital Clínico Universitario de Valladolid).

BACKGROUND: Several studies have found a high percentage of inadequate admissions to Internal Medicine Departments. In order to try to alleviate this situation, the Immediate Care Clinics of the Internal Medicine Department (ICCIMD) was created, to study those patients who are suspected of having a serious disease, and whose physical condition allows them to undergo an out-patient study the day after having visited the Emergency Department. The tests requested will take precedence over the rest of the consultations. METHODS: Descriptive, retrospective study, through the review of the clinical records of the patients who came to the ICCIMD during the first two years. RESULTS: Our service admitted 726 people in the ACCIMD, 52.2 % males, average age of 54.12 years old. A total of 18.6 % of the patients required hospital admission; this admission being carried out at the first medical examination in 66.7% of the cases. In most cases, it can be related with shortening a study that would have lasted longer. In spite of this, we consider that 1.4 daily admissions have been avoided. Mean time devoted to this study was about 33.20 days, much greater than that expected, because of the high prevalence of non-specific disease and hospital organization deficit. It was decided to study 76.6% of the patients sent, their diagnosis being achieved in 63.3% of the total number of patients. Nevertheless, the ICCIMD was inadequate, as hospital admission was required or the patient was sent to other specialities in the 27.3% of the cases. CONCLUSIONS: We think that the ACCIMD can be useful to improve efficiency of Internal Medicine Department, although, to do so, the significant problems found must be solved.
