Introduction and Objectives: Although the ophthalmic manifestations appear to be associated with the coronavirus disease 2019 (COVID-19), there is not enough evidence. Hence, the aim of this study was to determine the various types and frequency of ophthalmic manifestations in patients recovered from SARS-CoV-2 infection in Mexico., Material and Methods: This retrospective, observational and descriptive study included all patients recovered from SARS-CoV-2 infection attending the tertiary level hospital of Mexican Social Security Institute (IMSS) from June 2020 to June 2022. During the hospital admission of patients, the demographic data such age, name, gender was recorded. Ophthalmologic examination was performed under torchlight by an ophthalmologist in the Department of Ophthalmology from IMSS. Data was compiled and statistically analyzed using Fisher's exact test and Spearman correlation., Results: A total of 3081 SARS-CoV-2-positive patients were recorded, of which 318 (10.32%) met the inclusion criteria. Of them, 21 (6.60%) had ophthalmic manifestations and the female-to-male ratio was 1.6:1. The mean age (±SD) was 47.95±15.27 years and the median (interquartile range) time from the diagnosis of COVID-19, as defined by positive SARS-CoV-2 RT-PCR testing, to detection of the ophthalmic manifestation was 31 (142) days. The most common ocular manifestation was orbital mucormycosis (23.80%). Interestingly, the presence of ophthalmic manifestations was not associated with severe COVID-19 (p=0.665)., Conclusions: The ophthalmic manifestations are infrequent in patients recovered from severe COVID-19. Nevertheless, further large sample studies are needed to confirm these findings., (Copyright © 2023 Sociedad Española de Oftalmología. Published by Elsevier España, S.L.U. All rights reserved.)

Introduction: Chronic hypersensitivity pneumonitis (CHP) is an interstitial lung disease with limited treatment response and bad prognosis. Sometimes it is indistinguishable from idiopathic pulmonary fibrosis (IPF) becoming one of the main differential diagnosis. The aim of our study is to compare survival and functional decline between these two entities., Methods: Survival and functional decline more than 10% in FVC were compared using Kaplan Meier (KM) method between patients with CHP and IPF. Cox proportional hazard analysis was used to identify independent predictors of survival and functional decline., Results: 146 patients were included, 54 with CHP and 92 with IPF. KM rate for 2 years survival was 0.71 (CI 95% 0,6-0,8) for CHP group and 0,83 (CI 95% 0,66 - 0,92) for IPF (p=0,027). Nevertheless this difference disappeared using Cox proportional hazard analysis, the adjusted HR for survival among CHP patients was 0,53 (CI 95% 0,25-1,15) (p=0,11). There was no difference in functional evolution between the two groups. KM rate for a decline more than or equal to 10% was 0,64 for CHP (CI 95% 0,43-0,79) and 0,78 for IPF (IC 95% 0,6-0,88) (p=0,22). This observation did not change after using Cox proportional hazard analysis., Conclusions: Our study shows that both IPF and CHP are fibrosing interstitial diseases with a similar evolution and survival. It might be possible that therapeutic approach in patients with CHP should change in the light of these observations., (Copyright © 2019 Sociedade Portuguesa de Pneumologia.

Introduction: Domiciliary oxygen therapy (DOT) is a treatment that requires a high level of cooperation from patients due to the time it takes every day. A high level of non-compliance has been determined among patients receiving DOT. The aim of our study was to assess the level of non-compliance and the influence of active tobacco consumption on compliance., Material and Methods: Patients were monitored in the home using direct and indirect methods, to assess both compliance and tobacco consumption., Results: The level of non-compliance detected by indirect methods was 22.6%, and 66.3% by direct methods. Tobacco consumption determined by indirect methods was 5.8%-8%, depending on the method used, and 16.2% when CO in exhaled air ≥10ppm was established as an indicator of tobacco use. The group of smokers complied with oxygen therapy for a significantly fewer number of hours per day (P<.001) than non-smokers., Conclusions: There is a high level of therapeutic non-compliance and a significant percentage of patients receiving DOT continue to smoke. Compliance must be monitored, and the correct use of DOT must be emphasized. Additional efforts should also be made to help smokers with DOT to stop smoking, since continued smoking impacts negatively on therapeutic non-compliance., (Publicado por Elsevier España, S.L.U.)

Objective: To quantify the degree of compliance with the recommendations of the clinical practice guidelines published in 2009 by the ERS and the ESTS regarding the preoperative assessment of risk of lung resection in daily clinical practice at a tertiary hospital., Method: A prospective, observational study of real-time data collected from consecutive patients who had been referred for evaluation from September 2009 to December 2010. We recorded the presence or absence of the recommended studies included in the algorithm, their results and, when a test was missing, the reasons why it was not performed. Hospital mortality and cardio-respiratory morbidity rates are also presented., Results: 173 patients were evaluated. In 171 cases, lung resection was performed, with a mortality of 1.2% and a cardio-respiratory morbidity of 11.7%. The failure rate of the first level of the algorithm was 4.6% and for the second level (VO(2max) test) it was 26%. The absence of exercise tests was mainly due to hospital structural problems and the patients' inability to perform it. Out of the patients who performed the exercise testing, 31 reached a VO(2max) of 20 ml/kg-min or more and underwent surgery without calculation of FEV(1)ppo and DCLOppo; 35 patients required the calculation to determine their operability and in 2 cases the intervention was not recommended due to functional inoperability of the patient., Conclusions: The validation process found lack of compliance with the proposed algorithm in 18.5% of the cases basically due to the absence of the exercise tests. The rate of adherence to the algorithm recommendations should be improved before performing any other validation studies., (Copyright © 2011 SEPAR. Published by Elsevier Espana.

Aims: To determine the incidence of falls at acute hospital level and to compare this incidence with that found in the observational study with the notified falls., Method: We used a prospective observational study to register patient falls, with daily follow-up in the medical-surgical hospital units, and reviewed the notification of falls records. The patient monitoring was conducted between December 2008 and March 2009 at Fuenlabrada University Hospital. The accumulated incidence of falls was calculated, the association between qualitative variables, and the validity of the notification of falls record with regards to the reference pattern, the observational study., Results: A follow-up has been completed 1,001 patients, finding an accumulated incidence of 1.6% of the followed-up patients, compared to a notified incidence of 0.9%. No statistically significant differences were found (P=.167. The notification of falls record had a Kappa index of 0.24, with a sensitivity of 18.75% and a specificity of 99.39%, compared to the reference, the observational study., Conclusion: The incidence of falls practically doubles when using data from observational studies as opposed to those from notification systems., (Copyright © 2010 Elsevier España, S.L.

Introduction and Objectives: Traditionally, the oral glucose tolerance test has been useful to diagnose unknown diabetes. Recently, the American Diabetes Association committee has accepted glycated hemoglobin ≥ 6.5% as a criterion for unknown diabetes. The aim was to determine the benefit of glycated hemoglobin for diagnosing unknown diabetes and also create a predictive model that adjusts the indication for oral glucose tolerance test in coronary patients., Methods: We examined the glycemic profile of 338 coronary patients without previous diagnosis of diabetes, applying 2010 American Diabetes Association criteria. A unknown diabetes risk predictive model was developed using logistic regression analysis, and then validated in another cohort., Results: Using the glycated hemoglobin criteria and/or fasting plasma glucose, unknown diabetes was diagnosed in 26 patients. The remaining patients were classified according to oral glucose tolerance test as follows: unknown diabetes 53 (17%), prediabetes 144 (46.2%), and normoglycemic 115 (36.8%). The diagnostic method for unknown diabetes was fasting plasma glucose in 25.3%, glycated hemoglobin in 7.6%, and oral glucose tolerance test in 67.1%. A risk model including fasting plasma glucose, glycated hemoglobin, left ventricular ejection fraction, age, and noncoronary vascular disease was shown to effectively predict unknown diabetes after oral glucose tolerance test: area under the ROC curve 0.8 (95% confidence interval: 0.74-0.87). When the oral glucose tolerance test is restricted to patients with a risk score >6 (31% of our sample) we properly identify 83% of unknown diabetes cases (sensitivity: 75%, specificity: 73%, positive predictive value: 40%, negative predictive value: 93%). The model was adequately validated in another cohort of 115 patients (area under the ROC curve 0.84 [95% confidence interval: 0.74-0.95])., Conclusions: In coronary patients, glycated hemoglobin alone failed to detect many cases of unknown diabetes. However, its inclusion in a risk prediction model leads to optimizing the usefulness of oral glucose tolerance test., (Copyright © 2010 Sociedad Española de Cardiología. Published by Elsevier Espana.

Introduction: we present our preliminary experience and results of practising the prostate enucleation technique using a diode laser (DiLEP) and intravesical morcellation, following the same principles of holmium laser enucleation (HoLEP)., Materials and Method: we endoscopically treated benign prostate hyperplasia with DiLEP in 17 patients over a period of five months. They were all followed up for three months with flowmetry and IPSS. We have described the prostate enucleation and morcellation technique in detail, as well as the materials required to perform them. We have also commented on the lessons learned having practised on more than 300 cases with HoLEP, with a view to applying this new technology., Results: the mean age was 74.2 and the mean prostate volume was 61.26 (47-110) cc. The mean loss of haemoglobin was 2.1 (1.4-3.1) gr/dl. There were no major consequences or complications. All the patients were discharged from the hospital 24 hours after the operation. The improvement in the IPSS (22.3±4.1 vs. 7.1±1.06) and in the Q max (7.14±2.6 vs. 21.4±3.6) was sustainable., Conclusions: It is the first description of the DiLEP technique for the surgical treatment of benign prostate hyperplasia. We believe the results obtained are promising and that they could signify some advantages as opposed to HoLEP. However, prospective randomized studies are required to confirm this opinion., (Copyright © 2010 AEU. Published by Elsevier Espana. All rights reserved.)

Objectives: Evaluate the introduction of the enucleation with Holmium laser in our center, including the surgeon's learning curve by the analysis of the patients., Materials and Methods: 150 procedures have been analyzed in a retrospective manner with an average follow-up of 11 months. Qmax, IPSS and Qol have been determined before surgery, at 6 months and 12 months, realizing their statistic analysis. PSA was measured before surgery and after 3 months. Complications, surgical time and hospital stay have been analyzed., Results: Average patient age was 72, 4 years. Average prostatic size was of 71,3 gr (18-150). Average hospital stay was of 22 h. Qmax before surgery, 6 months, 12 months was of 7,53 ml/s, 23,24 ml/s and 21,62 ml/s being statistically significant (p<0,01). Transfusion rate was of 1,3% and urethral stenosis rate of 4%. IPSS improvement at 6 and 12 months was statistically significant as well (p<0, 01)., Conclusions: Enucleation with Holmium laser is a safe and effective technique with lower complication rate than TURP, included during the learning curve.

Background and Objective: Different scientific societies propose the use of scales of severity and additional criteria (AC) in order to determine the setting for the treatment of Community-Acquired Pneumonia (CAP).The objective of this study is to correlate the risk regarding three clinical prediction rules (PSI, CURB-65 and PSCRUXO-80) and AC with the effectiveness of hospital at home (HaH)., Patients and Method: Evaluation of cases of CAP referred from the Emergency Unit to HaH between January 2000 and May 2008. They were classified regarding three risk scales and presence of AC and its association with the effectiveness of HaH during the treatment was analysed., Results: 146 women and 181 men were admitted, (mean age, 60.3 years). The average stay in HaH was 8.6 days. Two patients died, 25 (7.7%) were admitted to hospital, 219 progressed favourably throughout and 81 after overcoming complications. Hospital at Home was effective in 92.3% of total patients. The rate was 85% for those in PSI=IV or V with or without additional criteria; 80% for CURB-65=2 and 77.5% for a PSCURXO-80 score of 10-19. The effectiveness of HaH is inversely related to severity., Conclusions: Hospital a Home (HaD) is an effective and safe care option for many cases of CAP in which hospital admission is normally recommended on the basis of prediction rule scores or additional admission criteria., (Copyright © 2009 Elsevier España, S.L.

The BREATHE-5 study demonstrated that bosentan, an oral endothelin receptor antagonist, provides clinical benefits in patients with Eisenmenger's syndrome. As a result, the European Medicines Agency (EMEA) approved its use for this indication. However, follow-up in that study was limited to 16 weeks and patients with complex congenital heart disease were excluded. We assessed the effect of long-term bosentan treatment in 10 patients with complex congenital heart disease and Eisenmenger's syndrome. In the mean clinical follow-up period of 25 months, all patients reached the target dose without developing side effects and without experiencing a change in arterial oxygen consumption at either rest or maximal exercise. Moreover, there were significant changes in clinical parameters: NYHA functional class improved from 3.3+/-0.7 to 2.5+/-0.9 (P=.002) and the 6-minute walk distance increased from 266+/-161 m to 347+/-133 m (P=.015).

Introduction and Objectives: The coexistence of heart and dental disease is common and antiplatelet therapy with aspirin and clopidogrel following a percutaneous intervention can interfere with dental practice. Our aim was to study dentists' knowledge of percutaneous coronary interventions and their approach to affected patients., Methods: A questionnaire was used to evaluate the knowledge of 100 randomly selected dentists in Spain about coronary stents, antiplatelet therapy, and guidelines prepared by American medical societies, including the American Dental Association, and to determine how frequently they consulted a cardiologist., Results: Data were collected from 100 dentists. Of these, 17 had no knowledge of coronary stents, but only one did not interrupt dual therapy: 12 consulted a cardiologist and the remaining four discontinued therapy themselves. Of the 83 who knew about stents, only 28 (34%) understood the difference between bare metal and drug-eluting stents. The drug clopidogrel's name was known by 21%, while 60% recognized one of the drug's commercial names and 45% recognized the other. Of the 83 aware of stents, 48 (58%) knew of the possibility of stent thrombosis, but only three knew about possible mortality. Cardiologists were consulted before dental procedures in 83% of cases. Only 36% knew about the existence of the guidelines., Conclusions: Although Spanish dentists' knowledge of coronary interventions was limited, in the majority of cases a cardiologist was consulted before a patient taking dual antiplatelet therapy was treated. Only a small percentage of those questioned knew of the existence of American medical society guidelines.

Background and Objective: Patent foramen ovale (PFO) is more frequent in migraine patients and is a cause of brain infarct among patients under 55 years old. Our goal was to study the association between PFO and migraine in ischemic stroke patients under 55 years old., Patients and Method: Observational study with inclusion of consecutive stroke patients admitted to a stroke unit (1995--2005). We selected patients under 55 years of age with first-ever acute cerebral infarction of cryptogenic origin. Demographic data, vascular risk factors, stroke vascular territory, stroke severity, the presence of PFO and/or atrial septal aneurysm (ASA) in echocardiography and functional status at discharge by the modified Rankin Scale score were analysed according to previous migraine., Results: From a total of 130 patients, 76 were males. The 13.8% had previous migraine, 3.9% among male and 27.8% among female (p < 0.001). Migraine patients were younger than non migraine ones (p = 0.041) and had a higher frequency of vascular risk factors (not significant [NS]). Stroke severity and functional status at discharge were similar in both groups. Previous history of migraine was associated with FOP (38.9% vs. 26.8%; NS) and FOP plus ASA (odds ratio = 5; 95% confidence interval, 1.422-17.580). The latter association was higher in female (33.3% vs. 0%; NS)., Conclusions: Previous migraine is more frequently associated with double interatrial septal abnormality (PFO plus ASA) in cerebral infarct patients under 55 years of age. This association could be higher in women.

Unlabelled: Pressure ulcers (PU) are the most frequent injuries in critical patients whose management is the responsibility of the nurses. The first step for its prevention is to determine the patients at risk; however the usual risk assessment scales (Norton, Braden, etc.) do not have adequate specificity to do this., Aim: To study the validity of a current risk assessment scale of pressure ulcers in intensive care (EVARUCI)., Design: Prospective, descriptive study., Subjects: Adult patients admitted to Intensive Care Unit (ICU) in the Hospital of Fuenlabrada without PU from February, the 1st, 2005 to January, the 31st, 2006. Demographic data were obtained from the admission records. Data on EVARUCI were daily collected and the patients were studied until they developed 1 of 2 outcomes: a) they developed a PU, or b) they left the ICU (death or exit to other nursing ward)., Methods: Four validity indexes were used: sensitivity, specificity, positive predictive value and negative predictive value. The area under the curve (AUC) of the receiver operating characteristic (ROC) was also used. These indicators were applied to the mean scores during the entire stay and to the initial and final scores in both groups (PU and NO PU). The SPSS v. 12.0 was used for the statistical analysis., Results: A total of 97 patients were included, 62 of whom finished the study. Eleven patients (17.74%) developed PU. Of these, 57.69% were grade I. The most frequent site was in the sacral area (26.92%) and heels (23.08%). The results of the mean of the scores on the EVARUCI mean, initial and final data were: sensitivity (100%, 100%, 90.91%), specificity (68.63%, 49.02%, 92.16%), positive predictive value (40.74%, 29.73%, 71.43%) and negative predictive value (100%, 100%, 97.2%). AUC of ROC was 0.938, 0.909, 0.952, respectively., Conclusions: The EVARUCI scale is valid to detect patients at risk of development PU in ICU.

Background and Objective: The study is aimed at improving our knowledge about the functional impairment of the psoriatic arthritis through a multicentral series., Patients and Method: We have designed a transversal and multicentral study (centers of the same geographical area), including 343 patients with psoriatic arthritis. Eight medical centers have participated. Patients have been divided depending on the assistential level where they are visited. We have collected the following data: sex, age, assistential level, duration of psoriasis and arthritis, age at onset of psoriasis and arthritis, clinical form, ARA functional impairment, number of tender and swollen joints, presence of dactylitis, distal interphalangeal affection, axial involvement, ostheolisis or nail lesions, erithrocyte sedimentation rate (ESR), C-reactive protein, hemoglobine, leucocites, platelets, HLA-B27 and rheumatoid factor., Results: 7.14% of the patients were significatly disabled (ARA functional class III and IV). 30.32% were patients visited in a primary assistential level, 30.90% in a secondary assistential level and 38.78% a tertiary and universitary hospital. We found statistically significant correlation between III and IV functional classes and age, assistential level, ostheolisis, corticoid treatment, ESR, leucocites, platelets and number of tender joints., Conclusions: We find a better functional capacity in our patients than in other studies. The inclusion of patients from different assistential levels instead of just patients visited in a tertiary hospital might be the cause of this difference.

Objectives: To assess the effectiveness, respiratory status, services of origin and outcome of patient with exacerbated COPD attended in Hospital at Home (HaH) regimen., Patient and Method: Study of patients with an exacerbated COPD in HaH from Vitoria-Gasteiz, Spain during the period March 1999-October 2004, in whom hospital admission had been recommended after medical assessment. We studied: age, gender, patient's stay, oxygen-saturation or arterial blood gas analysis, FEV1 (basal), dyspnea status (basal and current), coexisting diseases, exacerbation causes, Services of origin, use of home nebulizers and oxygen therapy, intravenous drugs, course (discharges/admissions/deaths). We analyzed the number of visits to the Emergency Department and hospital admissions 90 days before and after discharge from Hospital at home., Results: A total of 302 patients who generated 522 cases with exacerbated COPD were accepted, 81% of whom are men. Means stay was 11 days (0-111). Three hundred ninety six (76%) of the cases were discharge from HaH, 111 (21%) had to be hospitalized for different reasons, on 13 (2.5%) died. Of these, 43% came from the Respiratory Department and 39% from the Emergency one. Mean FEV1 was 45.4. A total of 89% of the patients had dyspnea 4/4 and 34% 3/4 when seen and 9% of the patients had pneumonia. During the 90 days following discharge from Hospital at Home, the number of visits to the Emergency Department and the rate of hospital admissions decreased significantly (p < 0.001)., Conclusions: Our data confirm that Hospital at Home is a good alternative to conventional hospital admission for the management of patients with exaxerbated COPD.

Background and Objective: The objective of this project is to investigate the factors predicting mortality and mean length of stay in patients diagnosed with unstable angina (UA) during admission to the Intensive Care Unit or Critical Care Unit (ICU/CCU)., Patients and Method: A retrospective cohort study including all the UA patients listed in the Spanish ARIAM register. The study period comprised from June, 1996 to December, 2003. The follow-up period is limited to the stay in the ICU/CCU. One univariate analysis was performed between deceased and live patients; and another between prolonged and non-prolonged stay patients. Three multivariate analyses were also performed; one to evaluate the factors related to mortality, another to evaluate the variables associated to percutaneous coronary intervention (PCI) and another to evaluate the factors associated to the prolonged mean stay in ICU/CCU., Results: 14,096 patients with UA were included in the study. The UA mortality rate during ICU/CCU admission was 1.1%. Mortality was associated to Killip classification, age, the need for CPR, development of cardiogenic shock, development of arrhythmia (such as VF, sinus tachycardia or high-degree atrioventricular block) and diabetes; whereas patients who smoke were associated to a lower mortality rate. PCI was only performed in 1,226 patients (8.9%), increasing over the years. The PCI-predicting variables were: age, being referred from another hospital, smoking, presenting prior acute myocardial infarction (AMI), complications consisting of cardiogenic shock or high-degree atrioventricular block and being treated with oral beta blockers. The mean length of stay in ICU/CCU was 3.15 (18.65) days (median, 2 days), depending on age, a coronariography having previously been performed, the Killip classification, having required coronariography and PCI or echocardiography or mechanical ventilation, and presenting complications such as angina that is difficult to control, arrhythmia, right ventricular failure or death., Conclusions: The factors are associated to mortality were; greater age, diabetes, Killip classification, arrhythmia, cardiogenic shock and the need for CPR, whereas smoking is associated to a lower mortality rate. The patients on whom PCI was performed represent a less severe population. Management has changed over the years, with an increase in PCI. A prolonged mean length of stay is associated to the appearance of arrhythmia, right or left heart failure, angina that is difficult to control, age and PCI.

Objective: To assess the effectiveness of therapy, type of infection, hospital department of origin and outcome of 515 cases of infection requiring home intravenous antibiotic therapy treated by the home care service., Methods: The clinical records of patients undergoing intravenous antibiotic therapy through the home care service over a 6-year period were retrospectively reviewed., Results: A total of 439 patients (244M/195F; mean age, 55.9 years, range 7-96) requiring 515 courses of home intravenous antibiotic therapy were reviewed. Mean duration of antibiotic therapy was 7.9 days (1-58). Urinary (42.3%) and respiratory infections (25.8%) were the most frequent indications for home treatment. Most patients were referred from the emergency room (50.5%) followed by the Internal Medicine Department (11.5%) and Oncology Department (11.1%). Ceftriaxone was the most widely prescribed antibiotic (41.8%) followed by aminoglycosides (35.3%) and glycopeptides (11.7%). In 49 cases electronic infusion pumps were used, with ceftazidime being the predominant antibiotic (32.7%) in these cases. Hospitalization was required in 7% of patients due to infectious disease-related complications. Clinical outcome was positive in 79% of the patients, with improvement in 90% of patients from the emergency room, Conclusions: The advantages of home care services to provide home intravenous antibiotic therapy are evident. More than half of the patients were referred from the emergency room and 90% of these progressed well. The presence of medical and nursing staff qualified to handle infectious diseases is necessary, as well as continuing home care.

Young male patient clinically and radiologically diagnosed of a tumour in IX right rib. A subsequent study with bone scintigraphy showed other areas of focal uptake in the skull, ribs and left trochanterian region. The biopsy of the costal lesion showed a fibrous dysplasia in the clinical context of a McCune-Albright syndrome. The convenience of using complementary imaging techniques is discussed to establish adequate therapeutic behavior.

Improvements in the diagnosis and surgical treatment of congenital heart disease during infancy and childhood have resulted in an outstanding increase in the prevalence of these entities during adulthood. Congenital heart disease in the adult represents a new diagnostic challenge to the consultant cardiologist, unfamiliar with the anatomical and functional complexities of cardiac malformations. Assessment of adult congenital heart disease with imaging techniques can be as accurate as in children. However, these techniques cannot substitute for a detailed clinical assessment. Physical examination, electrocardiography and chest x-rays remain the three main pillars of bedside diagnosis. Transthoracic echocardiography is undoubtedly the imaging technique which provides most information, and in many situations no additional studies are needed. Nevertheless, ultrasound imaging properties in adults are not as favorable as in children, and prior surgical procedures further impair image quality. Despite recent advances in ultrasound technologies such as harmonic or contrast imaging, other diagnostic procedures are sometimes required. Fortunately, transesophageal echocardiography and magnetic resonance imaging are easily performed in the adult, and do not require anaesthetic support, in contrast to pediatric patients. These techniques, together with nuclear cardiology and cardiac catheterization, complete the second tier of diagnostic techniques for congenital heart disease. To avoid unnecessary repetition of diagnostic procedures, the attending cardiologist should choose the sequence of diagnostic techniques carefully; although the information this yields is often redundant, it is also frequently complementary. This article aims to compare the diagnostic utility of different imaging techniques in adult patients with congenital heart disease, both with and without prior surgical repair.

Background and Objective: Hospital at Home might become a suitable alternative to traditional hospital admissions for several exacerbated chronic diseases. Congestive heart failure represents an important workload at the hospital level. In this study we present the results of our experience with congestive heart failure patients attended in Hospital at Home regimen during the period 1999-2001., Patients and Method: In 1999 we initiated a program to refer patients with congestive heart failure to Hospital at Home care. The program was agreed by the departments of emergency, cardiology, internal medicine and hospital at home. During the period 1999-2001, 158 patients (mean age = 76) were attended. Ninety one (58%) were women. At the moment of admission, 103 patients (68%) were on functional status IV of the NYHA., Results: On average, patient's stay on hospital at home was 12,8 days. One hundred and twenty three (78%) of them were discharged, 29 (18%) had to be referred back to conventional hospitalisation and six (4%) died. During the 90 days following the discharge from Hospital at Home, the number of visits to the emergency department and the rate of hospital admissions decreased significantly., Conclusions: Our data confirm Hospital at Home as a valid option to conventional hospital admission for the management of patients with congestive heart failure.

Nowadays, it is estimated that 85% of the infants born with congenital heart disease (CHD) will survive to adulthood, thanks mainly to surgical or therapeutic procedures performed during infancy or childhood. The clinical profile and disease pattern of adults with CHD is changing. The prevalence of certain adult CHDs, such as tetralogy of Fallot, transposition of the great arteries or univentricular heart, is rising, but these conditions have practically become new diseases as a result of therapy. Most surviving patients present residua, sequelae, or complications, which can progress during adult life. These disorders can present electrophysiological disturbances, valvular disease, persistent shunts, myocardial dysfunction, pulmonary or systemic vascular disease, problems caused by prosthetic materials, infectious complications, thromboembolic events, or extravascular disorders involving multiple organs or systems. In tetralogy of Fallot, the most striking problems that affect long-term prognosis are pulmonary valve regurgitation, right ventricle dysfunction, and atrial or ventricular arrhythmias. The main problems appearing after physiological atrial repair of transposition of the great arteries are related to right ventricular function, since it is structurally unprepared for systemic circulation, and atrial arrhythmias. Surgical repair of univentricular heart using Fontan techniques should be considered a palliative procedure that does not modify the underlying structural disorder and exposes the postoperative patient to severe complications and problems. The increase in the number of patients with CHD who will reach adulthood in the coming decades makes it necessary to carefully consider the new healthcare demands that are being generated, who should be responsible for them, and how and where solutions can be found.

A 39 year-old woman diagnosed with anomalous drainage of middle and lower right pulmonary veins to the inferior vena cava was corrected surgically by means of baffle with patch up to the left atrium. Early after the operation the patient related intolerance to small efforts and an episode of syncope. The cardiac catheterization demonstrated the presence of a severe stenosis in the inferior vena cava, in its union with the right atrium, that was successfully treated by means of intraluminal percutaneous dilation with a catheter of Inoue. After the procedure the gradient decreased and she improved tolerance to effort, which persisted 10 months later.

Introduction and Objectives: Ruptured sinus of Valsalva aneurysm to right cardiac chambers is an uncommon lesion in Western countries. The prognosis is usually serious unless the condition is promptly treated surgically. For this reason an accurate anatomical and functional evaluation is necessary. The main purpose of this report is to compare the usefulness of multiplane transesophageal echocardiography with transthoracic echocardiography and angiocardiography in the preoperative evaluation of ruptured sinus of Valsalva aneurysm to right chambers., Patients and Method: Since January 1990, 9 patients (mean age 36,3 18 yr, 6 males) with ruptured sinus of Valsalva aneurysm to right chambers were studied. The pathogenesis was congenital aneurysm in 6 patients, aortic prosthesis endocarditis in one and two cases of iatrogenia: during a percutaneous mitral valvuloplasty and after cardiac surgery. Transthoracic echocardiography was performed in all cases, transesophageal echocardiography in 7 and angiocardiography in 8. Two patients died before surgery, and 7 were successfully operated on., Results: Transesophageal echocardiography was more useful when compared to transthoracic echocardiography and angiocardiography in detecting: a) the fistula; b) the sinus involved; c) the right chamber affected; d) congenital aneurysms morphology and size; e) aneurysm prolapse through a ventricular septal defect, y f) the identification of other cardiac congenital or acquired anomalies., Conclusions: Multiplane TEE is the most accurate tool in the preoperative evaluation of ruptured sinus of Valsalva aneurysm to right chambers.

Aim: Value the utility of studies with 99mTc-DMSA with captopril (scintigraphy imaging and unilateral renal function) in identifying renovascular disease or renal disease in hypertension patients with high probability of renovascular hypertension., Methods: We studied 27 hypertension patients (12 males, 15 females) mean age 49 years, SD: 9.46, with high probability of renovascular disease. General analysis and radiology was made to all of them including renal arteriography as gold standard. Two renal scintigraphies with 99mTc-DMSA were made to all of them, baseline study and one hour after administration of 50 mg of captopril, a week between both studies. Renal scintigraphy (anterior and posterior images) was obtained 4 hours after the administration of 111 MBq (3 mCi) of 99mTc-DMSA and results were evaluated quantitatively and qualitatively calculating unilateral renal function. We considered positive for renovascular hypertension studies with decrease of more than five percentual points in unilateral renal function or a new defect absent in baseline study. Scintigraphic results were compared with arteriography to determine sensitivity, specificity and predictive values., Results: Arteriography demonstrated significant renal artery stenosis in 18.5% of patients. Renal scintigraphy with captopril using 99mTc-DMSA demonstrated sensitivity of 60%, specificity of 91%, positive predictive value of 60% and negative predictive value of 91%. We identified 3 patients with segmental defects of uptake consistent with chronic pyelonephritis scarring., Conclusions: Studies with 99mTc-DMSA using captopril present high specificity and are useful in patients with high probability for renovascular hypertension, identifying high number of patients with significant renal artery stenosis. The utility of DMSA in identify renal abnormalities, as specially pyelonephritis scarring, add value to renal studies with captopril using others tracers. DMSA could identify renal etiologies of renovascular hypertension different to renal artery stenosis.

Multiple congenital abnormalities in the structure of the tricuspid valve have been described and, the majority of cases could be considered as variations of Ebstein's anomaly. The onset of the symptoms and the diagnosis depend on the severity of the valve dysfunction and the right ventricular function and size. The age at diagnosis ranges from birth to adulthood, but a delayed diagnosis is rare when tricuspid regurgitation is severe. We cite as an example the case of a 73 year-old male classified as class I of the NYHA up to 5 months before, since then he developed progressive ascitis and edema on his legs. The physical examination suggested severe tricuspid regurgitation. We performed a transtoracic and transesophageal ecocardiogram that showed severe dysplasia in the tricuspid leaflets, severe regurgitation because of lack of adequate joining, dilatation of right chambers and right ventricular systolic dysfunction.

Objective: To determine reference values for ambulatory blood pressure in a random sample of Spanish elderly population, and their correlations with office blood pressure measurements., Methods: A representative random sample was obtained, stratified by sex and age, of 1,227 elderly subjects aged > 65 years, residents in an urban district, Barrio de Salamanca, or Madrid, Spain. In a random subsample (n = 420), two different blood pressure measurement approaches were performed: Office blood pressure and twenty-four hour ambulatory blood pressure (spacelabs 90207) were recorded, and two periods were defined: awake and sleeping, on the basis of the daily activities. Hypertension was defined if the average of casual blood pressure was > or = 140/90 mmHg or if there was current use of antihypertensive drugs., Results: Among the 420 participants, 333 ambulatory blood pressure monitorings were performed, 301 with valid registers, of whom 105 were receiving antihypertensive drug treatment. Office, 24 hour, awake and sleeping pressures averaged 147/84 mmHg, 128/72 mmHg, 132/77 mmHg and 122/66 mmHg respectively. Differences between whole sample and no treated group were not significant (p = 0.2), nor between the whole sample and the treated group (p = 0.7). Office blood pressure was markedly higher than 24 hour and awake averages (20 and 15 mmHg for systolic and 12 and 7 mmHg for diastolic, respectively). The differences between clinic and awake average blood pressures were significantly higher in females (p = 0.001) and increased, in both genders, as age (p = 0.001) and clinic blood pressure values (p < 0.000) increased. Correlation coefficients between office and the average awake period of the ambulatory blood pressures were of 0.60 and 0.48 for systolic and diastolic respectively. The ambulatory blood pressure value equivalent to 140/90 mmHg when obtained by causal measurement, was 15 mmHg lower when considering the 24 h average, or 10 mmHg lower when the awake averages., Conclusion: Ambulatory systolic and diastolic blood pressure values in the elderly are markedly lower than office values, specially in the case of systolic blood pressure. Differences in results between the two methods increase with age and with clinic blood pressure values, and are bigger in females. The cut-off point for ambulatory blood pressure monitoring equivalent to 140/90 mmHg in the casual measurement is of 125/75 mmHg for the 24 hour average and of 130/80 mmHg for awake average.

The objective of our work was to know the relationship between carbon monoxide (CO) levels in expired air and smoking habits among school youths and the relationships that can be established between CO level and some peculiar attitudes regarding consume by youths, such as the number of cigarettes, inhaling technique and time elapsed since the last cigarette was smoked. The study, of cross-sectional design, was performed in two high school centres and a total of 777 students who answered a questionnaire and had an expired air CO sample in their own schoolroom tested were enrolled. CO determination in the schoolroom was a simple and attainable technique for the pupils, as only 32 cases (4.1%) had to be excluded due to poor collaboration or poor technique. The mean (mean and SD) CO level in the control group (n = 247), made up by non-smokers nor tobacco tasters was 4.75 (2.46) ppm, statistically lower than among smokers (p < 0.001), but with no differences compared with non smokers (n = 563), who had a CO level of 5.23 (3.4) ppm. This figure was also lower (p < 0.001) than that obtained in the smokers (12.6 [6.3] ppm), made up of 214 pupils, with a mean consume of 2.7 (1.69) cigarettes/day. Among smokers the mean abstinence time since the last cigarette was smoked was 26 (44) minutes and 54% of them admitted to have smoked in the last 10 minutes. CO in expired air correlated significantly with the number of smoked cigarettes (r = 0.58; p < 0.001). Likewise, it correlated significantly with abstinence minutes (r = -0.38; p < 0.001). The time required for CO level to decrease below 10 ppm was 140 minutes in four cases and 120 minutes in 33 cases.

Reviewed are the current surgical methods for the treatment of mechanical complications after an acute myocardial infarction, specially the subacute ventricular rupture, the most frequent complication, and in which we have the greatest experience in the world. Mechanical complications constitute the second cause of death after myocardial infarction, following pump failure. The most frequent mechanical complication is ventricular rupture, which is the cause of death in 26% of the cases of acute myocardial infarction. The setting of solid diagnostic tools, with the association of echocardiographic and hemodynamic criteria, has permitted the identification of a large number of patients with subacute ventricular rupture before death, and has allowed them to be treated surgically. The surgical techniques have evolved to more conservative methods and, nowadays, nearly all the patients can be operated on without extracorporeal circulation and using sutureless techniques. The results is greater surgical survival with satisfactory functional status at follow up. The incidence of septal and papillary muscle rupture is considerably less frequent, but of great interest. The surgical results have been improved on the basis of early diagnosis, aggressive surgical attitude, and better reparative and myocardial protection techniques.

To study carboxyhemoglobin levels (HbCO) associated with use of different types of home heating and to evaluate the usefulness of measuring hemoglobin oxygen saturation. Nonsmoking patients with chronic respiratory insufficiency who were initially prescribed home oxygen therapy were enrolled in the study. One hundred four patients were studied in winter and summer (when heating was not used). The control group consisted of 92 hospitalized patients not exposed to carbon monoxide. Of the 104 patients 74.1% were men. Mean age was 72.33 (range 17 to 97 years) and 57.9% lived in rural areas. Mean HbCO in the control group was 1.53 +/- 0.96% (p = 0.01). Among the 39% who burned slack coal for heat, the mean HbCO was 4.63 +/- 2.87%. The 23.7% with central heating had HbCO levels of 2.15 +/- 0.87% (p < 0.0001). Pulse oximetry (SpO2) estimated higher hemoglobin oxygen than direct measurement (SaO2): 87.12 +/- 6% and 83.3 +/- 8%, respectively (p < 0.001). High HbCO concentrations are related to chronic exposure to slack coal fumes. Pulse oximetry, as opposed to SaO2, overestimates hemoglobin oxygen saturation in such cases.

The prevention of nicotine addiction involves a wide range of measures, including writing laws to preserve public health by protecting nonsmokers from smoke and discouraging smokers from consumption. Also important are campaigns to educate both parties (smokers and nonsmokers) about the negative effects of tobacco. The main antismoking law in Spain is the Health and Consumer Ministry's Royal Decree 192/1988 limiting the sale and use of tobacco with the aim of protecting public health. Other regulations have since been enacted by public administrations to complement that law. Research finding published in recent years have been the basis for major legal changes leading in two directions; toward standardizing laws existing in different countries and toward increasing restrictions on the advertising and sale of tobacco. Various scientific and social groups have demanded that current laws be made stricter. Little has been done, however, to assess the degree of vigilance and compliance, and consequently the efficacy, of current legislation. The aim of this study was to determine the level of compliance with the law in governmental institutions in Salamanca. We visited 30 centers and saw that while notices prohibiting smoking were visible in 80%, the number of smokers was high: 43% among workers (none of whom was in educational or medical centers) and 37% among the public. No posters warning of the dangers of tobacco were seen in any of the centers visited. It appears necessary to further restrict the sale and use of tobacco in public places, to enforce compliance with existing regulations and to increase the amount of information on the toxic effects of tobacco in order to gain the cooperation of both smokers and nonsmokers toward achieving smoke-free environments.

This study was designed to evaluate the gasometric and functional respiratory responses in chronic bronchitic patients with chronic respiratory insufficiency (CRI) under ambulatory oxygen therapy (AOT) with almitrine bismesylate (AB). It was a double-blind, placebo-controlled, randomized, prospective study which lasted three months and with a dosage regime of 50-100 mg/day of AB. Fiftyfour patients completed the study (28 in AB and 24 in the placebo (P) groups, respectively). All patients were males, with a mean age or 65 +/- 6.1 years. In the study of pulmonary function only airway resistance (Raw) was changed, with a significant decrease at the third month in the AB group compared with the P group (0.83 +/- 0.31 vs. 1.07 +/- 0.46 kpa/L.S), with a p value of 0.05 (mean +/- SD) and PaO2 which improved from 8.15 +/- 0.88 to 8.81 +/- 2.3 kpa (61.17 +/- 6.6 to 66.10 +/- 10 mmHg), with a p value of 0.05. AB therapy was well tolerated.

We present a case of non-fistulated, non-fissured arteriosclerotic pseudoaneurysm of the aorta in a patient with massive hemoptysis. The condition was resolved by resection, with the breach repaired with a Dacron patch. The diagnosis of thrombotic false aneurysm of the aorta was suspected after inspection of the digital angiograph and aortograph obtained by computed axial tomography. A review of the literature revealed 89 cases of non-surgically removable thoracic aortic aneurysm with hemoptysis; 72 of these cases involved aortobronchial fistulas. In only 1 case was the wall of the aneurysm intact, showing no fissures in spite of hemoptysis. The absence of fissuring or tearing in our patient may be accounted for by the delay of 10 days between the last bout of hemoptysis and surgical resection.

Almitrine bimesylate (AB) improves hypoxemia in an undetermined number of patients with respiratory failure. Our objective was to try to identify the patients likely to benefit from this treatment. We undertook a double blind study of AB (50-100 mg/day) vs placebo in 21 randomly chosen patients diagnosed as having chronic obstructive bronchitis who were receiving oxygen therapy in the home. The study lasted 3 months (T0 to T3). PaO2 rose from 51 +/- 5.3 to 58.5 +/- 10 mmHg (6.8 +/- 0.7 to 7.8 +/- 1.3 Kpa) in the 12 patients taking AB (p < 0.05). The remaining gasometric variables and results of functional respiratory exploration were unchanged. The 7 patients receiving AB who were defined as responding-whose PaO2 rose more than 5 mmHg (0.66 Kpa)-presented T0 values lower than those of the 7 non-responding patients in the same group, with respect to CO2 occlusion pressure, mean inspiratory flow and minute ventilation for both air and CO2. These variables can serve as predictors for gasometric response to AB.

Study of group of 61 patients, nephrectomized as a result of various diseases and who before and three months after surgery underwent blood pressure, effective renal plasma flow (EPFF) and unilateral renal function determinations in order to verify the compensating ability of the remaining kidney. Effective renal plasma flow was determined by a single injection and removal of six serial blood samples with 125-I-Hippuran. Unilateral renal function was determined from the relative uptake of 99mTc-DMSA 24 hours after injection. The patients were divided into four groups according to their overall and unilateral renal function as well as the presence or absence of hypertension. Patients with normal EPFF and symmetrical renal function showed a significantly increase in the function of the remaining kidney after surgery (p < 0.001). Patients with normal or slightly reduced EPFF (< 10%) and highly asymmetrical unilateral function as well as those with decreased EPFF (> 10%) and symmetrical or asymmetrical unilateral renal function did not increased the function of the remaining kidney after nephrectomy, and hypertensive patients whose blood pressure returned to normal values after nephrectomy had a decreased function of the remaining kidney after surgery (< 0.001). It is concluded that it is possible to predict the functional behaviour of the remaining kidney after nephrectomy, and that the compensating ability will basically depend on the previously existing (overall and unilateral) renal function as well as the presence or absence of hypertension.

Objective: To present three cases of primary Hypothyroidism with an atypical beginning., Design: Retrospective clinical observations. SITE. Health Centre (Primary Care)., Patients or Others Participants: Three women (aged 38, 43 and 51) who were studied in the consulting room: one who presented Macrocytosis and Hypercholesterolemia; the second, a bilateral palpebral oedema; and the third, dysfonia unaccompanied by any other symptom of Hypothyroidism., Main Measurements and Results: In the three cases, hypercholesterolemia was objectified, I4 diminished and TSH raised; in one of them T3 was normal, while it was low in the remainder., Conclusions: The alteracions observed are frequent in primary Hypothyroidism. But it is rare to find them on their own in the presentation of the clinical picture. Given this pathology's high prevalence, it is important to think of the pathology when presented with these atypical symptoms, and possibly to request the determination of TSH in isolation.

Background: Lauren's classification of gastric cancer is usually followed in epidemiological studies thus requiring evaluation of its reproducibility. This classification defines 2 principal histological types: intestinal and diffuse with different proportions in high and low risk areas possibly being associated to different causal factors., Methods: The concordance diagnosis in an aleatory sample of 81 gastric carcinomas stratified according to the participation of 14 hospitals in an epidemiological study of 354 cases and 354 controls was analyzed. The initial diagnosis carried out was compared by more than 20 pathologists with the reclassification diagnosis by consensus of 2 pathologists by the proportion of agreement or concordance observed in the kappa index. Keeping the final reclassification by consensus as a reference, sensitivity, specificity and predictive values were also calculated., Results: The proportion of concordance observed was of 78% for the intestinal and 90% for the diffuse with a kappa index of 0.55 and 0.74, respectively. Sensitivity for the intestinal type was of 88% and for the diffuse 81% with specificity being of 67% in the intestinal and 93% in the diffuse., Conclusions: Subjectivity in the interpretation of certain parameters necessary for histological diagnosis may be reduced by the elaboration of protocols in which the principal histological criteria to follow are detailed. Nonetheless, the distinction made between the two principal types, intestinal and diffuse, is valid enough to be used in multicenter epidemiological studies and in comparative studies.
