ABSTRACT
Epstein-Barr virus (EBV) is a herpesvirus whose only reservoir host is the human. It is transmitted by oropharyngeal secretions. Primary EBV infection is usually asymptomatic, but sometimes it causes infectious mononucleosis with fever, lymphadenopathies, splenomegaly and pharyngitis. Acute infection is diagnosed by serology (heterophile or specific antibodies). Immunofluorescence and molecular biologic techniques may be used to demonstrate the presence of EBV in biopsy specimens. Mild and transient elevations of serum aminotransferases are common, thus liver biopsy is usually not necessary to confirm the diagnosis. Severe cholestasis is rare (5%). We describe a patient with cholestatic hepatitis and acute EBV infection with atypical lymphocytes and positive anti-VCA IgM. The patient had taken drugs (ibuprofen, paracetamol and valerian). The bad evolution of the patient, the history of exposure to drugs, and the few cases of cholestatic hepatitis due to EBV infection reported, led us to consider liver biopsy. Molecular biologic techniques confirmed the presence of EBV in liver tissue however histologic features did not exclude the toxic aetiology or the concomitant effect of drugs and EBV infection.

El virus de Epstein-Barr (VEB) es un herpesvirus cuyo único huésped es el hombre, al que infecta por vía orofaríngea. La primoinfección generalmente es asintomática o cursa como una mononucleosis infecciosa que se caracteriza por fiebre, adenopatías, esplenomegalia y amigdalitis. El diagnóstico de la infección aguda suele ser serológico (anticuerpos heterófilos o específicos para el VEB), aunque el virus también puede detectarse en los tejidos mediante inmunohistoquímica o por técnicas de biología molecular. Habitualmente la infección por el VEB produce una alteración leve y autolimitada de las transaminasas (AST y ALT), por lo que no suele precisarse una biopsia hepática, y solo en el 5% causa una hepatitis aguda colestásica (HAC). Presentamos a un paciente con una HAC e infección aguda por el VEB, con linfocitos atípicos en sangre periférica y anticuerpos IgM contra la cápside VCA, que había tomado tóxicos (ibuprofeno, paracetamol y valeriana). La evolución tórpida del cuadro, la relación cronológica con la exposición a fármacos y los escasos casos publicados de HAC atribuidos al VEB, recomendaron realizar una biopsia hepática. Aunque el estudio de biología molecular en el tejido hepático resultó positivo para el VEB, los hallazgos morfológicos no permitieron excluir el origen tóxico ni la posible interacción entre fármacos y el propio virus en la etiología del cuadro

Despite universal acceptance of the value of elective hernia repair, many patients present with incarceration or strangulation, which are associated with significant morbidity and mortality. We reviewed 147 patients who underwent emergency surgery for incarcerated groin hernias during a 10-year period in order to analyze the presentation and outcome in our practice. Median age of the patients was 70 years. There were 77 men and 70 women. Femoral hernias were seen in 77 patients and inguinal hernias in 70. Coexisting diseases were found in 82 cases (55.8%). Bowel resection was required in 19 patients (12.9%). The overall and major morbidity rates were 41.5% and 9.6%, respectively. The mortality rate was 3.4%. Longer duration of symptoms, late hospitalization, concomitant diseases, and high ASA class were found to be significant factors linked with unfavorable outcomes. Because of high morbidity and mortality associated with incarceration, elective repair of groin hernias should be done whenever possible.

Celiac disease can present great clinical heterogeneity. Its association with a series of intestinal and non-intestinal diseases, whether immunologically mediated or otherwise, presents a higher than normal frequency. We present a patient with celiac disease and Budd-Chiari syndrome of unknown cause. This association has previously been described only in isolated cases in northern Africa. The appearance of this case in Spain reveals that the coexistence of both processes in a single patient is unlikely to be due to environmental or geographical factors.

BACKGROUND/AIMS: We compared the response to interferon-alpha 2a in 35 patients with antibody to HBeAg (anti-HBe) and 20 patients with HBeAg in serum, and histological features of chronic hepatitis B. METHODOLOGY: Patients were treated with 4.5-6 MU of interferon-alpha 2a, three times a week for 12 months, and followed for 30.8 +/- 13.5 additional months. RESULTS: All of them had elevated serum levels of aminotransferases and positive test for hepatitis B virus-DNA in serum. Patients with anti-HBe-positive chronic hepatitis were older and had higher serum aminotransferase levels than HBeAg-positive patients, but no differences were seen between both groups with respect to sex, history of acute hepatitis, mode of transmission of the infection or histological appearance before interferon therapy. Serum levels of alanine transaminase became normal and hepatitis B virus-DNA undetectable by PCR at the end of therapy in 25 (71%) of anti-HBe-positive patients and in 10 (50%) of HBeAg-positive patients (P > 0.05). Although 10 (29%) of the anti-HBe-positive and none of the HBeAg-positive patients relapsed, no significant difference was seen in the rate of sustained response (43% vs. 50%, respectively). The histological improvement was similar in both groups. CONCLUSIONS: The results of this study indicated that biochemical, virological and histological response to 12-month interferon-alpha 2a therapy was similar in patients with anti-HBe antibody than in patients with the classical HBeAg-positive of chronic hepatitis B.

INTRODUCTION AND OBJECTIVES: The impact of acute myocardial infarction in labour activity changes from one country to another as well as patients' characteristics. Our purpose was aimed to learn the main demographic, professional, clinical and therapeutic variables which might affect the return to work after suffering a myocardial infarction in our environment. METHODS: 584 patients treated consecutively in our Coronary Unit for 4 years, aged under 65, were studied. The following aspects were analyzed: age, sex, previous ischaemic heart disease, previous working condition, professional level, economical area of labour activity, main therapeutic procedures and complications, number of days of sick leave, posterior labour status and date of invalidity or death, should it occur. The minimum follow up period was two years. RESULTS: 65.3% of patients were regularly working before suffering the myocardial infarction. Mean length of sick leave after myocardial infarction was 243.9 days although it changed according to age and economical areas. 56.6% of the patients returned to work according to age (odds ratio = 0.92), high professional status (odds ratio = 2.14), economical area of services (odds ratio = 2.03), and the presence of previous anginal attacks (odds ratio = 1.73). CONCLUSIONS: In our environment, patients less likely to resume their work after suffering a myocardial infarction are older, working in agricultural and industrial areas, with a lower professional level and without known ischemic heart disease antecedents.

The mechanisms by which glucocorticoids are effective in acute liver rejection therapy are not entirely clear. The aims of this study were to characterize the intrahepatic immunological phenotype in acute liver rejection, as well as the effect of glucocorticoids on cytokine-stimulated hepatocyte cell lines. Biopsy sections from these patients were studied by immunohistochemistry. Cytokine-stimulated hepatocyte cell lines treated with glucocorticoids were evaluated by flow cytometry. The intrahepatic expression of both beta2-microglobulin conformational epitope and intercellular adhesion molecule-1 was higher in acute rejection than in resolving rejection. Interestingly, glucocorticoids were able to modulate in vitro the cytokine-induced expression of these molecules on hepatocyte cell lines. Beneficial effects of the glucocorticoid treatment appear to be associated with a modulation of a beta2-microglobulin conformational epitope and the intercellular adhesion molecule-1 on intrahepatic cellular targets in the acute rejection process.

INTRODUCTION AND OBJECTIVES: The length of hospital stay for uncomplicated myocardial infarction is still a debatable issue. Our study tries to establish the rate of patients amenable early discharged and the safety of this practice. PATIENTS AND METHODS: We studied retrospectively the clinical features, in-hospital events and 30-day follow up of 238 patients discharged early (5 or 6 days) during the last three years. These patients were compared with the remaining group of 929 patients discharged after a conventional stay (mean 10.4 days) in the same time frame. RESULTS: The mean hospital stay in the early discharged group was 5.4 days. They had no ischemic, arrhythmic or haemodynamic complications in the acute phase. In the 30-day follow up there was only one death (at the 14 th post-myocardial infarction day) and 17 readmissions to the hospital, none with re-infarction. By contrast, there were 14 deaths and 43 readmissions among the patients with the standard stay at the hospital. CONCLUSIONS: At least 20% of patients with uncomplicated myocardial infarction can be discharged early. This practice seems to be safe in low risk groups, and is not associated with a higher rate of complications when compared with longer hospital stays.

Abdominal ultrasonographic findings of Gaucher's disease had been reported, but a specific pattern has not been described. We report here a patient with an abdominal sonographic pattern which was concluded to be strongly suggestive of Gaucher's disease: solid focal splenic lesions with different patterns (hypoechoic, hiperechoic and mixed nodules associated with hypoechoic irregular areas) and bright liver and spleen echo pattern with posterior beam attenuation. Gaucher's disease was subsequently confirmed by determination of leukocyte beta-glucosidase activity and mutations of glucocerebrosidase gene.

OBJECTIVE: The objective of this study is to analyze the value of the electrocardiogram in the identification of the coronary artery responsible for acute inferior myocardial infarction. MATERIAL AND METHODS: One hundred consecutive patients with acute inferior myocardial infarction were studied, 67 with a lesion in the right coronary artery and 33 in the circumflex artery. The ST segment changes in the inferior, lateral, precordial and right-chest leads were analyzed, as well as the arithmetic sum of the ST segment in the inferior and V2 leads (II + V2, III + V-2 and aVF + V2). We also developed a diagnostic process based on a stepwise approach of three electrocardiographic criteria: a) elevation of the ST segment in DI; b) arithmetic sum of the ST magnitude in DIII + V2 < 0; c) depression of the ST segment in V4R. RESULTS: This study shows that the most useful parameters to predict (with a specificity of 100%) the lesioned coronary artery in acute inferior myocardial infarction are: a) the arithmetic sum of the ST segment: aVF + V2 > 0, for the right coronary artery; b) the arithmetic sum of the ST segment: III + V2 < 0, for the circumflex artery; c) the arithmetic sum of the ST segment: aVF + V2 > 1 mm, for the proximal right coronary artery. CONCLUSIONS: The incorporation of these three criteria in an algorithm diagnostic system allows us to locate the coronary artery responsible for acute myocardial infarction with 100% sensitivity and specificity.

PIP: This article discusses deficits in postpartum and postabortion care for women in developing countries. Postpartum and postabortion care frequently does not include family planning counseling. The risk of poorly timed or unwanted pregnancies is increased with a woman's inability to obtain effective contraception. Family planning programs must now address unmet need for contraception in postpartum and postabortion services, especially among rural women and adolescents. Programs need to focus on comprehensive reproductive health care. Women who deliver in medical settings may not receive contraceptive counseling after a delivery. A return to the hospital may not occur unless there are complications. Traditional birth attendants should be included in programs that provide postpartum care. Notwithstanding the lack of postpartum programs in many health settings, there are also constraints to reproductive health care in postpartum and postabortion family planning services. Sometimes family planning lacks institutional support and is poorly integrated into postpartum programs. Cultural barriers, provider biases, a lack of adequately trained personnel, legal barriers, and inadequate client-centered services interfere with delivery of family planning. Natural family planning methods are not always included in family planning services, even when culturally appropriate. The 1990 International Conference on Postpartum Contraception in Mexico and the 1993 International Workshop on Postpartum and Postabortion Family Planning in Ecuador made recommendations for improving postpartum family planning. Two key steps to improved services include training providers to counsel clients effectively and training program managers to adopt more gender-sensitive approaches to service delivery. Institutional and community support should be built on identifying needs and opportunities.^ieng

BACKGROUND: We wanted to investigate the influence of viral genotype on the severity of liver injury and response to interferon and whether the level of viremia differs in accordance with genotype, severity of liver disease, and response to interferon in patients with hepatitis C virus (HCV) infection. METHODS: We studied 118 patients with HCV-related liver disease. HCV genotypes were determined with a line probe assay, and serum HCV RNA levels with a competitive reverse transcription polymerase chain reaction assay. RESULTS: HCV type 1b was the most prevalent genotype (88%). It was present in 100% of cirrhotic patients, with or without hepatocellular carcinoma (HCC), but only in 78% of patients with chronic hepatitis (P < 0.001). The response to interferon was better in patients infected with non-1b HCV genotypes (P = 0.002). In a multivariate analysis non-1b HCV genotypes and a low hepatic fibrosis correlated with a favorable response to interferon. Among patients with chronic hepatitis those infected with HCV type 1b were older (P < 0.001), and age was the only independent factor associated with HCV type 1b. Viremia levels differed neither between genotypes nor in response to interferon and was significantly lower in patients with cirrhosis and HCC. CONCLUSIONS: HCV 1b was associated with more severe liver disease and a worse response to interferon therapy. Non-1b genotypes and a lower liver fibrosis were the only independent predictors of a favorable response to interferon. Levels of HCV viremia differed neither among different genotypes nor in response to interferon and decreased with advanced liver disease.

In order to identify the electrocardiographic changes that occur in right-chest leads V3R-V8R for the most significant diagnosis of the responsible coronary artery of acute myocardial infarction, the authors performed a prospective study on 66 patients in whom coronary arteriography was done between the first and twelfth weeks after suffering the infarction. Electrocardiograms were done within the first six hours after the onset of symptoms. Lesions of the right coronary artery were found in 46 patients--27 at a proximal level and 19 at a distal one--and in 20 patients the circumflex coronary artery was injured. The electrocardiographic findings were studied in 2 groups of leads: V3R-V4R and V5R-V8R. An ST elevation equal to or higher than 0.5 mm and the presence of Q waves in V3R-V4R are specific markers of lesions of the right coronary artery (P < 0.001). Lowering of the ST segment in V3R-V4R is a specific marker of a circumflex artery lesion (P < 0.001). An ST elevation equal to or higher than 1 mm in V3R-V4R is specific for a proximal lesion of the right coronary artery (P < 0.001). No specific marker for a lesion of the distal right coronary artery was identified, its more significant characteristic being an "isoelectrical" ST segment (between 0 and 0.4 mm), an rS morphology and positive T waves in V3R-V4R.

In order to evaluate electrocardiographic changes in the diagnosis of the artery responsible for inferior myocardial infarction, a prospective study was performed on inferior and V2 ST segment deviation and its correlation using the arithmetic sum: II + V2, III + V2, and aVF + V2. A group of 66 patients with inferior acute myocardial infarction (AMI) was studied. A standard 12-leads electrocardiogram was performed within six hours of the onset of chest pain. Coronary arteriography was performed on each of the patients between one and twelve weeks after infarction. Right coronary artery (RCA) lesion was found in 46 patients, 27 at a proximal level and 19 at a distal level; in 20 patients the left circumflex coronary artery was affected. The isolated value of the magnitude of the inferior ST segment is not an efficient parameter for identifying the artery responsible for inferior AMI. In lead V2 all the patients with a lesion of the left circumflex artery showed ST segment depression > or = 1 mm (P < 0.001) and all those presenting ST segment elevation had stenosis of the proximal RCA. The most useful parameters for identifying the artery responsible for inferior AMI, with 100% specificity are: (1) for occlusion of the RCA, the arithmetic sum of ST segments: aVF + V2 > 0, with 86.9% sensitivity (P < 0.001); (2) for occlusion of the left circumflex artery III + V2 < 0, with 90% sensitivity (P < 0.001); and (3) for proximal occlusion of the RCA: aVF + V2 > or = 1, with 96.2% sensitivity (P < 0.001). No specific marker was observed for distal occlusion of the RCA. The value of the arithmetic sum of the ST segment: III + V2 between 0 and 0.9 was the most significant, with 94.7% sensitivity and 95.7% specificity (P < 0.001).

We report a patient suffering from mitral insufficiency after isolated rupture a papillary muscle as a result of a car accident with blunt chest trauma. The diagnosis is often difficult due to related multiple lesions which vary the clinical picture. Physical exploration, electrocardiogram, enzymatic and nuclear scan lack adequate sensitivity and specificity. Echocardiography appears to be the most reliable noninvasive diagnostic method now available.

We report a patient with a proximal right coronary artery lesion in whom opposite shifts of ST segment in V4R lead were observed during and after exercise. ST-segment depression was provoked by exercise, while ST-segment elevation appeared in the recovery phase. We speculate that different degrees of myocardial ischemia (non-transmural vs transmural) may explain this apparently paradoxical response.
