Abstract
We examined associations between short-term exposure to traffic-related air pollutants (TRAP) and airway inflammation and lung function in children with asthma, and whether these associations are modified by chronic psychological stress. Residents of underresourced port-adjacent communities in New Jersey were concerned about the cumulative impacts of exposure to TRAP, particularly diesel-engine truck emissions, and stress on exacerbation of asthma among children. Children with asthma aged 9-14 (n = 35) were recruited from non-smoking households. We measured each participant's (1) continuous personal exposure to black carbon (BC, a surrogate of TRAP) at 1-min intervals, (2) 24-h integrated personal exposure to nitrogen dioxide (NO2), (3) daily fractional exhaled nitric oxide (FeNO), and (4) lung function for up to 30 consecutive days. Personal BC was recorded by micro-aethalometers. We measured daily FeNO using the NIOX MINO, forced expiratory volume in one second (FEV1), and forced vital capacity (FVC) using Easy One Frontline spirometers. Chronic stress was measured with the UCLA Life Stress Interview for Children. The association was examined using linear mixed-effect models. In the fully adjusted model, an interquartile range (IQR) increase in BC at lag 0-6 h before the FeNO measurement was associated with 8 % (95 % CI: 3 % - 12 %) increase in FeNO, whereas an IQR increase in BC at lag 7-12 h and lag 0-24 h were associated with 6 % (95 % CI: 2 % - 11 %) and 7 % (2 % - 12 %) FeNO increases, respectively. There were no significant lung function changes per IQR increase in BC. No interactions were observed between chronic stress and BC on FeNO. Chronic stress was negatively associated with individual average FeNO levels. Our findings suggest that higher levels of BC exposure within the prior 24 h increased airway inflammation levels in children with asthma, with the strongest effect observed within the first 6 h.

Abstract
BACKGROUND In patients with metastatic colorectal cancer (mCRC), the treatment options are limited and have been proved to be affected by rat sarcoma virus (RAS) mutational status. In RAS wild-type (wt) patients, the combination of anti-epidermal growth factor receptor (EGFR) monoclonal antibodies with chemotherapy (CT) is more effective than CT alone. On the other hand, RAS-mutated patients are not eligible for treatment with anti-EGFR antibodies. CASE SUMMARY Eleven patients with initially RAS-mutated mCRC were followed from diagnosis to May 2022. At the time of cell-free DNA determination, five patients had undergone one CT line, five patients had undergone two CT lines, and one patient had undergone three CT lines (all in combination with bevacizumab). At the second and third treatment lines [second line (2L), third line (3L)], patients with neo-RAS wt received a combination of CT and cetuximab. In neo-RAS wt patients treated with anti-EGFR, our findings indicated an increase in progression-free survival for both 2L and 3L (14.5 mo, P = 0.119 and 3.9 mo, P = 0.882, respectively). Regarding 2L overall survival, we registered a slight increase in neo-RAS wt patients treated with anti-EGFR (33.6 mo vs 32.4 mo, P = 0.385). At data cut-off, two patients were still alive: A RAS-mutated patient undergoing 3L treatment and a neo-RAS wt patient who received 2L treatment with anti-EGFR (ongoing). CONCLUSION Our case series demonstrated that monitoring RAS mutations in mCRC by liquid biopsy may provide an additional treatment line for neo-RAS wt patients.

Abstract
Abstract
Introduction
Beta-blockers (BB) are recommended in patients with previous acute myocardial infarction (AMI), aiming to reduce morbidity and mortality. Their benefit is greater in patients with associated left ventricular dysfunction. However, in patients with atrial fibrillation (AF) its prognostic benefit is controversial.
Purpose
To assess and compare the in-hospital and 1-year prognostic impact of BB prescription after acute coronary syndrome (ACS), in patients with previous or de novo AF, and in patients with sinus rhythm (SR).
Methods
This was a national multicentre retrospective study of patients hospitalized for ACS between October 2010 and December 2021. A total of 35279 patients was included, and divided in two groups according to the prescription or not of BB. Patients with previous history of ischemic heart disease (myocardial angina, AMI or coronary revascularization) or heart failure, as well as presenting in Killip class IV or submitted to coronary artery bypass graft during admission were excluded. The impact of BB prescription on in-hospital and 1 year mortality rates, in patients with AF versus SR, was compared.
Results
A total of 14906 patients was selected, 82.5% with and 17.5% without BB prescription. Most patients were in SR (90.2%), with 9.8% presenting previous or new-onset AF.
Patients without BB prescription were older (67±14 vs. 63±13 years) and had more comorbidities, namely valvular disease (2.3% vs. 1.2%, p<0.001) and chronic pulmonary obstructive disease (7.1% vs. 3.1%). The mean left ventricular ejection fraction was 53±13% in patients without BB prescription and 52±11 in the group with BB prescription (p<0.001). In-hospital and after discharge BB prescription was less frequent in AF patients (80.2% vs. 82.5% and 74.7% vs. 78.8%, respectively).
The in-hospital mortality rate was 2.2%, 1.3% in the BB group and 6.6% in patients without BB prescription (p<0.001). At 1 year, mortality rate increased to 5.1%.
BB prescription was associated with lower in-hospital mortality rate regardless of the rhythm, with an 81% risk reduction in SR (OR = 0.19, 95% CI 0.14–0.24) and 79% in AF patients (OR = 0.21, 95% CI 0.13–0.35). In a multivariate regression analysis, after adjusting for all the possible confounders, in-hospital BB prescription was associated with 70% of mortality risk (OR = 0.30, 95% CI 0.23–0.35).
Overall, after discharge BB prescription was associated with reduced 1-year mortality risk (HR = 0.57, 95% CI 0.44–0.73), although it didn't reach statistical significance in AF patients (p=0.413). Nevertheless, in a bivariate Cox regression, rhythm showed no impact on BB protective effect (p-interaction = 0.335). As expected, AF had a negative prognostic impact (HR = 3.85, 95% CI 2.66–5.02).
Conclusion
BB prescription was associated with reduced in-hospital and 1 year mortality rates. The prognostic benefit of BB therapy was equivalent in ACS patients in sinus rhythm and with previous or new-onset AF.

Abstract
BACKGROUND Traffic-related air pollution (TRAP) has been associated with increased risk of airway inflammation in children with asthma. While epigenetic changes could potentially modulate TRAP-induced inflammatory responses, few studies have assessed the temporal pattern of exposure to TRAP, epigenetic changes and inflammation in children with asthma. Our goal was to test the time-lag patterns of personal exposure to TRAP, airway inflammation (measured as fractional exhaled nitric oxide, FeNO), and DNA methylation in the promoter regions of genes involved in nitric oxide synthesis among children with asthma. METHODS We measured personal exposure to black carbon (BC) and FeNO for up to 30 days in a panel of children with asthma. We collected 90 buccal cell samples for DNA methylation analysis from 18 children (5 per child). Methylation in promoter regions of nitric oxide synthase (NOS1, NOS2A, NOS3) and arginase (ARG1, ARG2) was assessed by bisulfite pyrosequencing. Linear-mixed effect models were used to test the associations of BC at different lag periods, percent DNA methylation at each site and FeNO level. RESULTS Exposure to BC was positively associated with FeNO, and negatively associated with DNA methylation in NOS3. We found strongest association between FeNO and BC at lag 0-6 h while strongest associations between methylation at positions 1 and 2 in NOS3 and BC were at lag 13-24 h and lag 0-24 h, respectively. The strengths of associations were attenuated at longer lag periods. No significant associations between exposure to TRAP and methylation levels in other NOS and ARG isoforms were observed. CONCLUSIONS Exposure to TRAP was associated with higher levels of FeNO and lower levels of DNA methylation in the promoter regions of the NOS3 gene, indicating that DNA methylation of the NOS3 gene could be an important epigenetic mechanism in physiological responses to TRAP in children with asthma.

Abstract
Case
A 74 year-old white male with COPD, type 2 Diabetes, Atrial Fibrillation and a Pacemaker presented to our hospital for a routine echocardiography follow-up for mild to moderate Aortic Stenosis. His past social history was positive for moderate alcohol consumption but negative for tattoos, recent travel, illicit drug use, blood transfusion or chemical exposure. During evaluation in the echocardiography lab the patient had symptoms of dyspnea, fatigue and abdominal distension. He was hemodynamically stable and physical examination was positive for signs os ascites and inferior limb oedema, but disclosed no scleral icterus, asterixis, spider angiomata or overt hepatomegaly. There was a recent weight gain of 10kg. Cardiac and pulmonary auscultation was unrevealing. The echocardiogram revealed moderate left ventricle dysfunction (EF ∼40%), moderate aortic stenosis and a dilated inferior vena cava (31mm) with an image of a mobile mass in the confluence of the central hepatic vein with the inferior vena cava with extension to the right atrium. Initial blood chemistry and blood count revealed macrocytic anaemia; slight increased y-GT, C-reactive protein and NT-proBNP (6210pg/mL). The patient was admitted and anticoagulation with subcutaneous enoxaparin was initiated with echocardiographic follow-up. An abdominal ultrasound was performed which a hyperecogenic mass (71x47mm) adjacent to the right and left supra-hepatic veins, highly suggestive of hepatocelullar carcinoma. A triple-phase abdominal CT confirmed a nodular lesion 70x50mm on segment VIII, compatible with hepatocellular carcinoma (Fig.1). A cardiac magnetic resonance was performed documenting the tumor extension to the inferior vena cava and right atrium, suggestive of tumor thrombus (Fig.2). Multidisciplinary meeting enrolled the patient in palliative care. The right heart failure picture was refractory to medical treatment and the patient progressed to multi organ failure and a consumptive state. He died approximately 20 days after diagnosis.
Discussion
Intravascular tumor extension, also known as Tumor thrombus (TT) is a rare complication of some forms of cancer. In the late stages of Hepatocellular carcinoma (HCC) a TT can form in the portal or hepatic vein. These are usually detected during tumor workup or during evaluation of cardiorespiratory symptoms in a patient with a known abdominal carcinoma. Tumor invasion to the portal system is quite common while invasion to the inferior vena cava (IVC) and/or heart without invasion of the portal system is rare. Tumor extension to the RA or IVC, most patients were either symptomatic, had cirrhosis, or both. Our patient presented mainly with signs of right heart failure refractory to medical treatment and had no signs of portal invasion or hypertension in the various image modalities. The prognosis for a HCC with extension to the IVC or RA is grim, with a 1 to 4 months of mean survival regardless of treatment choice.

Abstract
AIMS Altering the length of time specimens are placed in fixative without compromising analytical testing accuracy is a continuous challenge in the anatomical pathology lab. The aim of this study was to determine under controlled conditions the effects of variable fixation time on breast biomarker expression in human breast cancer cell line-derived xenografted (CDX) tumours. METHODS CDX tumours using strong oestrogen receptor (ER)-positive, Her2-negative (MCF7) and weak ER-positive, Her2 equivocal (T47D) breast cancer cell lines were fixed for various times ranging from 1 to 336 hours in 10% neutral buffered formalin. CDX tumours were processed according to routine biomarker testing protocols and stained for ER and Her2 immunohistochemistry (IHC) and processed for HER2 fluorescence in situ hybridisation (FISH). The tumours were evaluated using Allred scoring for ER and current ASCO/CAP guidelines for Her2, and by objective cell counting methodology. RESULTS No differences were found in expression of ER in either MCF7 or T47D CDX tumours under variable fixation. T47D tumours displayed equivocal Her2 staining when fixed for 24 hours, but fixation for ≤8 hours resulted in consistently negative staining while tumours fixed for >72 hours demonstrated consistent equivocal staining (p<0.01). Cell counting assays revealed only a significant increase in sensitivity in tumours fixed for >72 hours (p<0.01). As expected, FISH results were unaffected by variable fixation. CONCLUSIONS Neither shortened nor prolonged fixation affects ER expression, consistent with previous findings. In equivocal Her2-expressing tumours, however, increasing fixation increased the sensitivity of Her2 IHC reporting while not affecting FISH.

Abstract
ContexteLe Metacognitions Questionnaire-30 (MCQ-30), développé par Wells et Cartwright-Hatton (2004) [1], est une échelle de mesure multidimensionnelle de facteurs métacognitifs impliqués dans le développement et la persistance de troubles psychiques. La théorie définitoire inhérente à cette échelle est résumée par Wells et Matthews [2] dans le modèle Self-Regulatory Executive Function (S-REF). Dans la dépression, une rumination pathogène serait induite par des pensées (croyances métacognitives évaluées par le MCQ-30) et des stratégies de contrôle qui perpétuent une cognition et des stratégies de coping inadaptées. Le but de notre étude est d’adapter et de valider une version française du MCQ-30 en évaluant ses propriétés psychométriques dans un échantillon de patients qui ont un diagnostic de dépression.MéthodesL’adaptation française de l’instrument a été réalisée après une traduction back-forward permettant une bonne validité de face. Elle est en cours de passation dans un échantillon de patients hospitalisés ayant un diagnostic de dépression établi selon les critères du DSM 4 TR. Le nombre de sujets nécessaires est estimé à 150 [3]. Une analyse factorielle confirmatoire permettra de vérifier la structure dimensionnelle à 5 facteurs retrouvée dans l’étude de validation de la version originale. Pour l’évaluation de la validité convergente, nous étudierons la corrélation des différents facteurs du MCQ-30 avec une mesure de l’anxiété d’état (Penn State Worry Questionnaire), de la rumination (Rumination on Sadness Scale), et de la dépression (Beck Depression Inventory). Hypothèses sur le comportement de l’échelle : en accord avec les validations étrangères, nous supposerons une corrélation positive et significative de la MCQ-30 avec les échelles sus-citées.RésultatsDes résultats partiels seront présentés et discutés à la lumière de la taille de l’échantillon.

Abstract
Many countries in sub-Saharan Africa have made antiretroviral therapy (ART) available in urban settings, but the progress of treatment expansion into rural Africa has been slower. We analysed routine data for patients enrolled in a rural HIV treatment programme in Zambézia Province, Mozambique (1 June 2006 through 30 March 2009). There were 12,218 patients who were ≥15 years old enrolled (69% women). Median age was 25 years for women and 31 years for men. Older age and higher level of education were strongly predictive of ART initiation (P < 0.001). Patients with a CD4+ count of 350 cells/μL versus 50 cells/μL were less likely to begin ART (odds ratio [OR]: 0.19, 95% confidence interval [CI]: 0.16-0.23). In rural sub-Saharan Africa, HIV testing, linkage to care, logistics for ART initiation and fears among some patients to take ART require specialized planning to maximize successes. Sustainability will require improved health manpower, infrastructure, stable funding, continuous drug supplies, patient record systems and, most importantly, community engagement.

Abstract
Anaemia is a common finding in elderly patients particularly in those with chronic kidney disease. Effective correction of anaemia improves survival and quality of life. The association between anaemia and a poor nutritional status as well as the presence of inflammation has already been documented. The aim of our study was to assess the impact of the nutritional and inflammatory status on darbepoetin dose requirements of elderly patients followed in a "Chronic Kidney Disease" outpatient clinic. We included 71 elderly patients (age>or=65 years) in a "Chronic Kidney Disease" outpatient clinic. Creatinine Clearance (CrCl) was estimated according to the Cockroft-Gault equation. Nutritional status was evaluated by biochemical and anthropometric parameters. Tumour Necrosis Factor-alpha (TNF-alpha), Interleukin-6 (IL-6) and high sensitivity C-reactive protein (hs-CRP) were used as biomarkers of inflammation. Our patients (56% males) with a mean age of 76.2+/-6.6 years were followed for 33.1+/-43.6 months. Mean eCrCl was 13.5+/-7.2 ml/mn/1.73 m2. All patients were under supplemental iron therapy and 74.7% needed darbepoietin (0.762+/-0.6 (microg/kg/week) to correct anaemia. Among the several variables regressed on darbepoietin dose, in a multiple regression model, only Hb, IL-6 and TNF-alpha levels and SGA score predicted the need for higher doses of darbepoietin. (r=0.677; r2=0.459). In Conclusion, in our pre-dialysis elderly patients, markers of a poor nutritional status (SGA and albumin) and inflammation (IL-6 and TNF-alpha) independently predicted the use of higher doses of darbepoietin to correct anaemia.

Abstract
OBJECTIVE The 5-year project in the province of Sofala was designed to improve access, quality and utilization of emergency obstetric care (EmOC) by strengthening rural hospitals and health centers and ultimately the health system's capacity to respond to emergencies more quickly and effectively. METHODS Implementation consisted of attention to infrastructure, human resource development, transportation and communication systems, and management. Specific management aspects that were targeted for improvement included: supportive supervision, logistics for supplies, equipment and drugs, record keeping, monitoring and evaluation, and quality improvement techniques such as maternal death audits. RESULTS Access to EmOC improved with an increase in the number of fully functional EmOC facilities from 4 to 18. The number of women with obstetric complications who were admitted for treatment in participating facilities tripled, and the proportion of those women dying declined by half. CONCLUSIONS Close collaboration and partnership with the provincial health directorate make the sustainability of many results likely while the replication of much of the Sofala model to other provinces is promising for the national strategy to reduce maternal mortality.

Abstract
Computational fluid dynamic (CFD) experimentation provides a unique medium for detailed examination of flow through complex embryonic heart structures. The purpose of this investigation was to demonstrate that streaming blood flow patterns exist in the early embryonic heart and that fluid surface stresses change significantly with anomalous alterations in fetal heart lumen shape. Stages 10 and 11 early human embryo hearts were digitized as calibrated two-dimensional (2D) cross-sectional sequential images. A 3D surface was constructed from the stacking of these 2D images. CFD flow solutions were obtained (steady and pulsatile flow). Particle traces were placed in the inlet and outlet portions of these two stages. Sections of the embryonic heart were artificially reshaped. CFD flow solutions were obtained and surface stress changes analyzed. Streaming was shown to exist, with particles released on one or the other side of the cardiac lumen tending not to cross over and mix with particles released from the opposite side of the cardiac lumen. Shear stress changes (stage 10) occur in the altered lumens. Streaming exists in steady and pulsatile flow scenarios in the embryonic heart models. There are differences in local shear stress distributions with surface shape anomalies of the fetal heart lumen. These observations may help shed light on the potential role of fluid dynamic factors in determining patterns of abnormal heart development.

Abstract
Scaled physical models can be useful in analyzing stage-specific hemodynamics in the embryonic human heart to address correlations between early physical stressors and myocardial wall responses. We generated models of the cardiac blood space from reconstructions of four digitized human embryo images from Carnegie Collection at the Armed Forces Institute of Pathology. From physical scale models manufactured by stereolithography, compliant sleeves can be created for flow dynamics studies. This novel use of Carnegie collection images and graphical modeling software provides tools for broadening our understanding of normal and aberrant heart formation.

Abstract
BACKGROUND/AIMS Clastogenic factors (CFs) are composed of lipid peroxidation products, cytokines and other oxidants with chromosome-damaging properties. They are regularly observed after radiation exposure and in chronic inflammatory diseases, where they are supposed to be risk factors for carcinogenesis. It appeared of interest to investigate their presence in the plasma of patients with chronic hepatitis C. METHODS CFs are detected by chromosomal breakage studies. They were compared to malondialdehyde (MDA), total plasma thiols (t-SH), alanine aminotransferase (ALT), viral load and histological data. RESULTS CFs were increased in 19 of 20 patients, 16 had increased MDA levels and 15 had decreased t-SH levels. Mean values were significantly different from the 20 controls (p<0.001). After the first 3 months of interferon treatment, all three markers showed significant improvement, but were not completely normalized. There was a positive correlation between CFs and necroinflammatory activity (p<0.03), while MDA was correlated with fibrosis (p<0.03). Viral load was correlated with necrosis and inflammation (p<0.05). CONCLUSION The presence of CFs in chronic hepatitis C confirms the occurrence of oxidative stress in this disease and could be useful in clinical trials for testing antioxidants. The CF test is a sensitive assay for the detection of oxidative stress and correlates with necroinflammatory activity.

Abstract
BACKGROUND/AIMS Hepatic stellate cell activation has a major role in the pathogenesis of hepatic fibrosis, considered to constitute part of the healing response to a necroinflammatory stimulus. However, steatosis per se, has also been shown to induce this activation. This study evaluates if hepatic stellate cell activation is present, and how it correlates with steatosis, in nonalcoholic steatohepatitis, whose hallmark is steatosis. METHODOLOGY Steatosis, hepatocyte damage, inflammation and fibrosis were graded from 0 to 3+, in liver biopsies from 15 well documented nonalcoholic steatohepatitis and 5 normal controls. Activated hepatic stellate cell activation were identified immunohistochemically using a monoclonal antibody raised against cytoplasmic alpha-smooth muscle actin, and semiquantitatively graded using a scoring method. RESULTS Nonalcoholic steatohepatitis patients showed significantly greater numbers of alpha-smooth muscle actin-reactive hepatic stellate cell than controls: hepatic stellate cell index of 3.6 +/- 1.9 versus 1.5 +/- 0.5, P < 0.05. The distribution of alpha-smooth muscle actin-reactive hepatic stellate cell was higher in the perivenular areas, than in the intermediate zone and portal area, with no significant association between steatosis and alpha-smooth muscle actin-expressing hepatic stellate cell. However, a significant association was found between portal and lobular inflammation and hepatic stellate cell index, r = 0.72, P = 0.0005 and r = 0.75, P = 0.0002, respectively. CONCLUSIONS This study demonstrates that hepatic stellate cell activation occurs in nonalcoholic steatohepatitis, clearly correlating with portal and lobular inflammation, but not with steatosis, suggesting that the mechanisms implicated in fibrosis in nonalcoholic steatohepatitis are probably related with inflammation.

Abstract
BACKGROUND/AIMS Hypergastrinaemia has been reported in liver cirrhosis; meanwhile, it is unclear whether it is associated with an increase in gastrin cell function. The serum gastrin concentration and the number of gastrin cells in antral biopsies were studied in patients with alcoholic liver disease. METHODS Immunocytochemical and quantification techniques were used to localize and determine the number of gastrin cells. RESULTS Slight non-significantly higher serum gastrin values were observed in the alcoholic liver disease patients compared with controls, but the individual variation within the groups was considerable. The frequency of gastrin cells did not differ between groups. However, the size of the gastrin cell nuclei was larger in patients with liver disease than in controls, indicating increased cellular activity. CONCLUSIONS Alcoholic liver disease, with a disturbed liver function, influences the gastrin cells. The observed alterations may reflect the effect of alcohol and/or malnutrition, or may be secondary to the influence of liver disease on other regulatory peptides.

Abstract
BACKGROUND AND AIMS Hepatic steatosis and nonalcoholic steatohepatitis (NASH) have been associated with obesity, non insulin-dependent diabetes mellitus and hyperlipidemia. The present study was designed in order to evaluate whether patients with steatosis/NASH presented common features with the metabolic syndrome. METHODS In 30 patients with nonalcoholic fatty liver the prevalence of hypertension and diabetes; the glucose/insulin profile, lipid profile, and serum leptin were evaluated and correlated with body composition and energy expenditure, assessed by bioimpedance spectroscopy and indirect calorimetry, respectively. Results were compared with a group of eight controls. RESULTS Obesity was present in 80% of patients, hypertension in 50% and non insulin dependent diabetes in 33%. Glucose metabolism was altered in 69%, with elevated insulin in 14 patients. Serum leptin, higher in women, was increased in patients: 33.9 +/- 38.9 vs 9.6 +/- 6.9 ng/ml, P< 0.05. There was a correlation between insulin and leptin, both of which correlated with body mass index, fat mass and percentage of body fat. Dyslipidaemia was found in 80% of patients: 45% presented low high density lipoproteins cholesterol, 58% high low density lipoproteins and 38% elevated very low density lipoproteins. CONCLUSIONS There is a strong association between nonalcoholic fatty liver and features of the metabolic syndrome, suggesting a simultaneous insulin resistance and decreased sensitivity to leptin.

Abstract
Liver involvement in patients with systemic lupus erythematosus (SLE) is considered rare. Previous treatment with potentially hepatotoxic drugs or viral hepatitis have usually been implicated as the main causes of liver disease in SLE patients. On the other hand, even after careful exclusion of these aetiologies, the problem remains whether to classify the patient as having a primary liver disease with associated autoimmune clinical and laboratory features resembling SLE, such as autoimmune hepatitis, or as having liver disease as a manifestation of SLE. We report the case of an elderly woman who presented with acute hepatitis, who had been diagnosed with SLE 14 years ago and who also had Sjögren's syndrome and anti-phospholipid's syndrome for several years. The histology depicted chronic active hepatitis and, after drug-induced hepatitis and viral hepatitis were excluded, the serological and clinical features were shown to be typical of liver damage caused by SLE. The patient was treated with azathioprine 100 mg/d and prednisone 30 mg/d. The clinical symptoms resolved in 10 days and the laboratory values were normal at the end of the first month of therapy. Prednisone was progressively reduced, during a period of 4 months, to 10 mg/d but azathioprine was kept to the same dose. One year after the diagnoses the patient is still in remission. Although uncommon, hepatic involvement is well recognised in SLE. The interest of this case lies in the differential diagnosis and recognition of this condition, which deserves an aggressive treatment.

Abstract
This chapter aims to provide a brief review on the enzyme family of lipases and esterases. The sequences, 3D structures and pH dependent electrostatic signatures are presented and analyzed. Since the family comprises more than 100 sequences, we have tried to focus on the most interesting features from our perspective, which translates into finding similarities and differences between members of this family, in particular in and around the active sites, and to identify residues that are partially or totally conserved. Such residues we believe are either important for maintaining the structural scaf-fold of the protein or to maintain activity or specificity. The structure function relationship for these proteins is therefore of central interest. Can we uniquely identify a protein from this large family of sequences--and if so, what is the identifier? The protein family displays some highly complex features: many of the proteins are interfacially activated, i.e. they need to be in physical contact with the aggregated substrate. Access to the active site is blocked with either a loop fragment or an alpha-helical fragment in the absence of interfacial contact. Although the number of known, relevant protein 3D structures is growing steadily, we are nevertheless faced with a virtual explosion in the number of known or deduced amino acid sequences. It is therefore unrealistic to expect that all protein sequences within the foreseeable future will have their 3D structure determined by X-ray diffractional analysis or through other methods. When feasible the gene and/or the amino acid sequences will be analyzed from an evolutionary perspective. As the 3D folds are often remarkably similar, both among the triglyceride lipases as well as among the esterases, the functional diversities (e.g. specificity) must originate in differences in surface residue utilization, in particular of charged residues. The pH variations in the isopotential surfaces of some of the most interesting lipases are presented and a qualitative interpretation proposed. Finally we illustrate that NMR has potential for becoming an important tool in the study of lipases, esterases and their kinetics.

Abstract
Maintenance of cerebral perfusion pressure is a prerequisite for the prevention of cerebral ischaemia. Physiological fluctuations in systemic perfusion pressure are compensated by cerebrovascular autoregulation. Cerebral perfusion reserve may be determined by assessing changes in cerebral blood flow using vasodilating stimuli. Transcranial Doppler has been used to assess cerebral blood flow speed in response to those stimuli. We describe a method using Transcranial Doppler with CO2 to analyse cerebral vasoreactivity. The method can be useful to determine hemodynamic reserve in different cerebral ischaemic diseases.

Abstract
It has been postulated that an impaired immune response may contribute to the progression of human papillomavirus (HPV)-associated preneoplastic lesions. Based on this hypothesis, we evaluated the cytokine production in the blood of patients with squamous intraepithelial lesions (SIL) of the uterine cervix. The levels of type-1 (interferon-gamma (IFN-gamma) and IL-12) and type-2(IL-4 and IL-10) cytokines were measured in whole blood culture supernatants of patients with low- and high-grade SIL and control women. There was no difference in IL-4 and IFN-gamma levels between patients with SIL and the control group. In contrast, the ratio of IL-12/IL-10 levels was significantly lower in patients with SIL compared with the control group. A lower IL-12/IL-10 ratio in women with SIL was also observed when peripheral blood mononuclear cell (PBMC) culture supernatants and plasma samples were analysed. In patients, neither the lower expression of the CD3epsilon chain nor the higher frequency of HLA-DRB1*1501 expression could be correlated with abnormal cytokine production. These results suggest that a part of the cytokine network, namely IL-10 and IL-12, is perturbed in patients with SIL. A better knowledge of the role of these cytokines in regulating the growth of HPV-associated SIL might have practical implications for the development of vaccines or immunomodulatory strategies in the treatment of cervical cancers.

Abstract
During 1995, we added gold sodium thiosulfate and potassium dicyanoaurate to the patch test standard series. Our purpose was to compare the reactivity of the gold salts, to determine the frequency of contact allergy to gold in our country, to compare our results with those of the Malmö group and, finally to try to clarify the clinical relevance 2853 patients were routinely tested and 168 patients answered a questionnaire similar to that used by the Malmö group. Contact allergy to gold was found in 23 patients, all women: 22 to gold sodium thiosulfate (0.78%), only 1 to potassium dicyanoaurate and 2 to both salts. All reactors had their ears pierced and were exposed to gold jewelery (mainly earrings). Simultaneous allergies to nickel and cobalt were statistically significant in patients with positive patch tests to gold sodium thiosulfate. Atopy was no more common among these patients.

Abstract
We report the case of a 34-year-old white man with recurrent episodes of abdominal pain, cholestasis and eosinophilia. The diagnosis of idiopathic hypereosinophilic syndrome (IHS) was made after exclusion of all known causes of eosinophilia. Liver biopsy revealed an eosinophilic infiltrate with biliary damage. The patient recovered after prednisolone treatment. We review the literature on the association between IHS and liver disease.

Abstract
Non Hodgkin's lymphoma revealed by hepatic manifestations is extremely rare. We describe here a 82-year old male patient who presented with a right subphrenic abscess and a solitary liver tumour that was shown to be a centrocytic lymphoma. Furthermore, asymptomatic cryptogenic liver cirrhosis was diagnosed. This previously unreported form of clinical presentation of a non Hodgkin's lymphoma as well as the association with liver cirrhosis are discussed in the context of the recent literature.

Abstract
Craniofacial infection is a major problem for the plastic and neurosurgical team. Previous successful experiences with free muscle and omentum flaps and the galea frontalis myofascial flap have been reported, avoiding disastrous complications after frontofacial advancements and the resection of skull base tumors. The authors report the clinical use of the galea frontalis myofascial flap in the treatment of anterior fossa CSF leaks. This flap provides an adequate sized and vascularized barrier between the cranial and nasal cavities through which the cells of the inflammatory response reach the target area. This technique was used in 11 cases with complete success; in-6 patients, repair of the anterior cranial base bone defect was performed with split calvarium bone grafts, harvested from craniotomy bone. In all the patients, neither the recurrence of the CSF leakage nor post-operative meningitis or its recurrence were observed.

Abstract
UNLABELLED The chronic elevation of Aminotransferases is one of the most frequent indications for percutaneous Liver Biopsy (LB). From a retrospective study of LB performed in the Hepatology liver Unit of Santa Maria Hospital, between 1989 and 1993, we correlated the histologic diagnosis with the etiology of liver disease, sex, age and the Aspartate aminotransferase/Alanine aminotransferase (AST/ALT) and Gama-Glutamyl transpeptidase (gamma GT) index in patients with chronic liver test abnormalities. 790 LB were reviewed retrospectively, of patients aged between 11 and 78 years, 68% males and 32% females. The most common etiology was Hepatitis C (34.6%), followed by Hepatitis B (20.1%) and alcohol (15.8%). Autoimmune diseases (Primary Biliary Cirrhosis and Autoimmune Hepatitis) were present in 3% of cases, and metabolic liver diseases in 1.4%. The distribution by sex revealed a predominance of Hepatitis C in both, alcoholic liver disease being more frequent in males (21.5% vs 3.9%). The main histological diagnoses were Chronic Active Hepatitis (27.2%), Liver Cirrhosis (19.5%), Steatohepatitis (9.5%) and minor lesions (24.6%). In alcoholic liver disease, 47.2% had Liver Cirrhosis and 16% Steatohepatitis; in Hepatitis B, Liver Cirrhosis was found in 12.6% and in Hepatitis C in 11.4%. Liver Cirrhosis had a prevalence between the 4th and 6th decade of life (82%) with a peak incidence in the 5th, and appeared earlier in Hepatitis B and later in Hepatitis C. The prevalence between sexes was similar. The main etiology of Liver Cirrhosis was alcohol (38.3%). The gamma GT index was greater in alcoholic liver disease (average 4.1) and was nearly twice in Hepatitis C than in Hepatitis B (1.7 vs 0.8). CONCLUSIONS 1) Hepatitis C in our Hepatology Unit was the main indication for Liver biopsy. 2) The prevalence of alcoholic liver disease is greater in males, being the main etiology of Liver Cirrhosis. 3) The progression to Liver Cirrhosis seems to be similar in Hepatitis B and C. 4) The progression to Liver Cirrhosis is similar in both sexes, being dominant in the 5th decade of life. 5) The progression to Liver Cirrhosis is earlier in Hepatitis B than in Hepatitis C. 6) A gamma GT index elevation, without alcohol abuse, is suggestive of Hepatitis C. 7) Autoimmune and metabolic liver diseases seem to be rare in Portugal.
