Abstract
Gout is a multisystem disease that may present in different ways. We report an elderly man who presented with a large ulcer of the left leg with hard yellow projections evolving for one year. Analytical study revealed a normal uric acid level, but histopathology showed a focal basophilic acellular material compatible with a gouty tophus. This tophus represents the cardinal feature of advanced gout and may present several challenges to wound care professionals. In fact, the ulcer in our patient persisted after one-year follow-up. Our aim is to alert clinicians about a rare cutaneous presentation of gout that may be increasingly diagnosed.

Abstract
Idiopathic pulmonary fibrosis (IPF) is a chronic interstitial lung disease of unknown cause that occurs sporadically, but it can also occur in families and so named as Familial Pulmonary Fibrosis (FPF). Some forms of FPF overlaps IPF features, namely the radiological and histological pattern of usual interstitial pneumonia (UIP). Genetic and environmental factors commonly play an important role in the pathogenesis of FPF and the most commonly identified mutations involve the telomerase complex. Here, we report a rare case of FPF in a male at the age of 44, in whom genetic testing showed heterozygous variants for the telomerase reverse transcriptase gene (TERT). Our report highlights the importance of compiling a thorough family history in younger patients identified with UIP serving as a resource for identifying the current and future genetic links to disease. Families with UIP hold a great promise in defining UIP pathogenesis, potentially suggesting targets for the development of future therapies.

Abstract
Background: Organizing pneumonia (OP) is classified as an acute/subacute pneumonia according to the American Thoracic Society/European Respiratory Society statement (2013 update). Although its clinical presentation, radiologic and histologic features are well established, data on the relevance of potential causes, corticosteroid doses and length, or management of relapses are based on heterogeneous series of patients. Objectives: The aims of this study were to describe clinical presentation, diagnosis and treatment of OP, explore potential causes, discuss strategies for managing relapses, and analyze prognostic factors. We also discuss our findings in relation to relevant data in the literature. Methods: We performed a cross-sectional study of all patients diagnosed with OP at a tertiary referral center in northern Portugal between 2008 and 2015. Results: Sixty-seven patients were diagnosed with OP over the 7-year study period. Dyspnea and cough were the most common presenting symptoms and approximately 30% of patients were hospitalized at the time of diagnosis. Approximately half of the patients were receiving drugs described as potential causes of OP. Microorganisms were isolated in approximately one-third of patients. Other potential causes identified were hematologic disorders, neoplasms, connective tissue diseases, myelodysplastic syndromes, immunodeficiencies, radiotherapy, and bird exposure. Cryptogenic OP was diagnosed in just 16 patients (23.8%). Corticosteroids were the most common treatment and 11 patients (16.4%) experienced relapse. Conclusions: The findings for this series of patients confirm the extreme variability of the contexts in which OP can occur and suggest that rather than a distinct, homogeneous clinicopathologic entity, OP is a non-specific reaction whose outcomes are dependent on the cause.

Abstract
INTRODUCTION Transbronchial lung cryobiopsy (TBLC) is increasingly used in the diagnosis of diffuse lung disease (DLD), but no data have yet been published on the learning curve associated with this technique. AIM To evaluate diagnostic yield, lung tissue sample length and area, and procedure-related complications in a cohort of TBLC procedures to define the learning curve and threshold for proficiency. METHODS Retrospective analysis of the first 100 TBLCs performed in different segments of the same lobe in patients with suspected DLD. We compared diagnostic yield, sample length and area, and complications between consecutive groups of patients. RESULTS The overall diagnostic yield for TBLC was 82%. Median sample length was 5.4mm (IQR, 5-6) and median area was 19.5mm2 (IQR, 13.3-25). Pneumothorax was the most common complication (18%). On comparing the two groups of 50 consecutive patients, a significant difference was found for diagnostic yield (74% vs 90%; p=0.04), sample length (5.0mm [2.5-16] vs 6.0mm [4-12;] p<0.01) and area (17.5mm2 [6-42] vs 21.5mm2 [10-49]; p<0.01). Logarithm regression was applied to median diagnostic yield and sample length and area for groups of 10 consecutive patients to define the learning curve, which plateaued after approximately 70 procedures. CONCLUSIONS Our findings suggest that proficiency in TBLC is achieved at approximately the 70th procedure; however they need to be validated in more series and cohorts.

Abstract
BACKGROUND Sarcoidosis is a systemic granulomatous disease of unknown etiology. Epidemiological studies of different populations are essential because clinical presentation, organ involvement, disease severity, and prognosis vary significantly according to region and population. The aim of this study was to assess epidemiological and clinical characteristics, staging factors, and clinical course in patients with sarcoidosis from a tertiary hospital in Oporto, Portugal. METHODS A retrospective analysis of patients with sarcoidosis and at least 2 years of follow-up evaluated at the Centro Hospitalar de São João between 2000 and 2014. RESULTS We identified 409 patients with sarcoidosis (females, 58.9%; mean age at diagnosis, 38.9±13.4 years; smokers, 14.4%]. All the patients were diagnosed according to the ERS/ATS/WASOG consensus statement and 64.1% had evidence of noncaseating epithelioid cell granulomas in biopsy specimens. Bronchoalveolar lavage was performed as part of the diagnostic work-up in 289 patients and 90.2% had lymphocytosis (CD4/CD8 ratio ≥3.5 in 60.9% of cases). Exertion dyspnea, cough, and constitutional symptoms were the most common presenting symptoms; 10.1% of patients were asymptomatic, 22.8% had Löfgren syndrome, and 50.5% had extrathoracic involvement. Radiographic stages of disease according to the Scadding criteria were as follows: stage 0 (5.2%), stage I (33.7%), stage II (47.0%), stage III (8.4%), and stage IV (5.7%). Impaired respiratory function was observed in 45.6% patients and was mostly mild. Systemic treatment was administered in 58.6% of cases. Overall, 45.3% of patients experienced disease resolution. CONCLUSION The epidemiological and clinical characteristics of this cohort of patients with sarcoidosis from the Oporto region in northern Portugal revealed epidemiological and clinical characteristics that were generally similar to those described in other Western Europe populations and in the US ACCESS study. However, we found a higher proportion of patients who progressed to chronic forms.

Abstract
Congenital pulmonary lymphangiectasia (CPL) and chylothorax (CC) are rare lymphatic developmental disorders. We report six clinical cases of CPL and CC that were admitted to our level III neonatal intensive care unit over the last 20 years. One case of unilateral CC was successfully treated with pleuro-amniotic shunt; three cases of bilateral CC were associated to lung hypoplasia, hydrops fetalis, and generalized lymphangiectasias; one case of CPL was associated with obstructive congenital heart defect; one case of unilateral CC was successfully treated with thoracocentesis and medium-chain triglyceride diet. Mortality was high (66.6%).

Abstract
The viability and survival of Lactobacillus acidophilus La5 under in vitro simulated gastrointestinal in probiotic dairy dessert was assessed. In addition, the effects of regular consumption of the dessert (5g/day) on the lipid profile, immune system, and antioxidant/biochemical status of Wistar rats were also evaluated after 2weeks of treatment. Adequate counts of L. acidophilus La-5 were observed regards the viability and gastrointestinal conditions. The probiotic dairy dessert was efficient in reducing the LDL-cholesterol, triacylglycerol and increased the HDL-cholesterol in serum. Aspartate amino transferase, alanine aminotransferase, total protein, albumin, heat shock proteins, immune system responses, and blood-cells counts (monocyte, lymphocyte, neutrophil and leucocyte) were not affected (p>0.05) after 15days of treatment. Overall, the probiotic dairy dessert may be a viable alternative to enhance the blood lipid profile and could be used to improve the antioxidant defenses.

Abstract
AIM To evaluate the clinical and epidemiological profile of women with breast cancer, managed in the Breast Service at Hospital Get6lio Vargas (HGV). MATERIALS AND METHODS A descriptive, observational cross-sectional study, involving 174 breast cancer patients, managed at the Breast Service at HGV in Teresina, in the northeast of Brazil, from May 2011 to June 2014. Epidemiological variables included age group, age at menarche, age at first childbirth, and menopause. The tumor characteristics studied were histological type, TNM classification, and staging. The results were organized in distribution tables. RESULTS Breast carcinoma was more common in patients aged 60 and over, in multiparous women, and in women who were menopausal before age 55. The most common histological type was ductal invasive carcinoma T2N1MO (Stage IIB) in 83 (48%) women. CONCLUSION The current study shows that the majority of carcinomas were Stage II or advanced tumors, with clinically positive axillary lymph node status and weak correlation with reproductive risk factors.

Abstract
Idiopathic pleuroparenchymal fibroelastosis (IPPFE) is a recently described rare entity, characterized by pleural and subpleural parenchymal fibrosis and elastosis mainly in the upper lobes. The etiology and pathophysiology are unknown. The prognosis is poor, with no effective therapies other than lung transplantation. IPPFE should be properly identified so that it can be approached correctly. This report describes two clinical cases with clinical imaging and histological features compatible with IPPFE.

Abstract
Disruption of the histone modification patterns is one of the most common features of human tumors. However, few genetic alterations in the histone modifier genes have been described in tumorigenesis. Herein we show that the histone methyltransferase SETDB1 undergoes gene amplification in non-small and small lung cancer cell lines and primary tumors. The existence of additional copies of the SETDB1 gene in these transformed cells is associated with higher levels of the corresponding mRNA and protein. From a functional standpoint, the depletion of SETDB1 expression in amplified cells reduces cancer growth in cell culture and nude mice models, whereas its overexpression increases the tumor invasiveness. The increased gene dosage of SETDB1 is also associated with enhanced sensitivity to the growth inhibitory effect mediated by the SETDB1-interfering drug mithramycin. Overall, the findings identify SETDB1 as a bona fide oncogene undergoing gene amplification-associated activation in lung cancer and suggest its potential for new therapeutic strategies.

Abstract
Whey protein hydrolysate (WPH) is capable of increasing muscle glycogen reserves and of concentrating the glucose transporter in the plasma membrane (PM). The objective of this study was to determine which WPH components could modulate translocation of the glucose transporter GLUT-4 to the PM of animal skeletal muscle. Forty-nine animals were divided into 7 groups (n=7) and received by oral gavage 30% glucose plus 0.55 g/kg body mass of the following WPH components: (a) control; (b) WPH; (c) L-isoleucine; (d) L-leucine; (e) L-leucine plus L-isoleucine; (f) L-isoleucyl-L-leucine dipeptide; (g) L-leucyl-L-isoleucine dipeptide. After receiving these solutions, the animals were sacrificed and the GLUT-4 analysed by western blot. Additionally, glycogen, glycaemia, insulin and free amino acids were also determined by standard methods. Of the WPH components tested, the amino acid L-isoleucine and the peptide L-leucyl-L-isoleucine showed greater efficiency in translocating GLUT-4 to the PM and of increasing glucose capture by skeletal muscle.

Abstract
Intense physical activity results in a substantial volume of stress and hence a significant probability of immunosuppression in athletes, with milk proteins being, perhaps, the most recommended protein supplements. Consumption of a probiotic cheese can attenuate immune suppression induced by exhausting exercise in rats. A popular Brazilian fresh cheese (Minas Frescal cheese) containing Lactobacillus acidophilus LA14 and Bifidobacterium longum BL05 was fed for 2wk to adult Wistar rats, which then were brought to exhaustion on the treadmill. Two hours after exhaustion, the rats were killed and material was collected for the determination of serum uric acid, total and high-density lipoprotein cholesterol fraction, total protein, triacylglycerols, aspartate aminotransferase, alanine aminotransferase, creatine kinase, and blood cell (monocyte, lymphocyte, neutrophil, and leukocyte) counts. Exercise was efficient in reducing lymphocyte counts, irrespective of the type of ingested cheese, but the decrease in the group fed the probiotic cheese was 22% compared with 48% in the animals fed regular cheese. Monocyte counts were unaltered in the rats fed probiotic cheese compared with a significant decrease in the rats fed the regular cheese. Most importantly, ingestion of the probiotic cheese resulted in a >100% increase in serum high-density lipoprotein cholesterol and a 50% decrease in triacylglycerols. We conclude that probiotic Minas Frescal cheese may be a viable alternative to enhance the immune system and could be used to prevent infections, particularly those related to the physical overexertion of athletes.

Abstract
INTRODUCTION Integrated PET/CT has become a fundamental tool in the preoperative assessment of non small lung cancer (NSCLC) providing useful anatomical and metabolic information to characterize tumoral lesions and to detect unsuspected metastatic disease. AIM To compare the agreement between clinical and pathological staging before and after the use of PET/CT. MATERIAL AND METHODS Retrospective study of patients with NSCLC who underwent potentially curative surgery throughout 10.5 years. Cohen's kappa coefficient was used to evaluate staging agreement. RESULTS One hundred and fifty patients were evaluated, 78% males, with a mean age of 65 (±9.6) years. Thirteen percent were submitted to neoadjuvant chemotherapy. PET/CT was performed in 41%. Global agreement between clinical and pathological staging was 51% (kappa=0.3639). There was a statistically significant difference between the staging results in patients who underwent PET/CT, when compared to the subgroup who did not (p=0.003). For those with PET/CT false negatives occurred in less 39%, false positives in more 12% and clinical and pathological staging coincided in more 27%. The overall results reflected an improvement in the agreement between clinical and pathological staging in the PET/CT subgroup (67%, kappa=0.5737 vs 40%, kappa=0.2292). PET/CT accuracy was enhanced when patients re-staged after neoadjuvant therapy were excluded and a substantial staging agreement was obtained for those who had the exam only for staging purposes (73%, kappa=0.6323). CONCLUSION Inclusion of PET/CT in NSCLC preoperative assessment improved the accuracy of the clinical staging, with a good level of agreement with pathological staging.

Abstract
There are literature data about the immunomodulatory properties of some macrolides in cryptogenic organizing pneumonia (COP) as an alternative to corticosteroids in mild disease or as adjuvant to standard therapy. A sixty-year-old female, with a controlled intrinsic asthma, presented with COP and recurrent respiratory exacerbations despite corticosteroid and immunossupressant therapy. Azithromycin (500mg, on alternate days) as an adjuvant to steroids was then started, with clinical and functional improvement and regression of lung infiltrates. Withdrawal of steroids was possible in one year, without evidence of relapse in the next six months. Azithromycin was maintained (three times per week) with no documentation of adverse side effects. This clinical case reinforces the potential role of macrolides anti-inflammatory properties in COP as corticosteroids adjuvant therapy.

Abstract
BACKGROUND Preservation of E-cadherin expression is usually related to non-invasive and well differentiated breast carcinomas. PURPOSE The aim of this study was to evaluate E-cadherin immunohistochemical expression in estrogen receptor (ER) positive and negative infiltrating ductal breast carcinomas. METHODS Twenty-three postmenopausal patients with Stage II, operable, infiltrating ductal breast carcinomas were divided into groups A (ER+; n = 13) and B (ER-; n = 10). E-cadherin immunohistochemical expression was assessed semiquantitatively according to membrane staining intensity and classified as negative (< 10% of cells with stained membranes), positive + (10-50% of cells stained) or positive ++ (> 50% of cells stained). Fisher's exact test was used to compare the distribution of staining intensity in the two groups (p < 0.05). RESULTS In group A (ER+), E-cadherin staining was positive in all cases: + (n = 3; 23%) and ++ (n = 10; 77%) compared to three cases (30%) in group B (ER-), + (n = 2; 20%) and ++ (n = 1; 10%). This difference was statistically significant (p < 0.0005). CONCLUSIONS The present results indicate that E-cadherin expression loss is significantly associated with ER-negative tumors and therefore with a more aggressive phenotype of invasive ductal breast carcinoma.

Abstract
The term Acute Fibrinous and Organizing Pneumonia (AFOP) has been proposed by Beasley et al for cases that do not fit into the histopathologic criteria of the recognized entities described as acute or subacute clinical presentations. The presence of intra-alveolar fibrin in the form of fibrin "balls" and organizing pneumonia with patchy distribution are the main histological features of this entity. We describe the case of a male patient with the diagnostic of AFOP made by surgical lung biopsy. He had a subacute presentation of symptoms consisting of productive cough, chest pain and fever. Bilateral infiltrates with patchy and diffuse distribution were the predominant features in his chest HRCT scan. The patient had a good clinical course after a treatment with prednisone and cyclophosphamide. Our hope in reporting this case study is to add some more data to the discussion of this new entity.

Abstract
The gastric mucosa of marmosets is devoid of UDPG-GT; phosphorylases; G-6-PA; F-1,6-PA; alanyl aminopeptidase and leucine aminopeptidase. Only the acid phosphatase was seen with a stronger reactivity in the chief cells. The other enzymes (LDH; G-6-PDH; 6-PGDH; NADPH2-TR; cis-aconitase; ICDH; SDH; MDH; cytochrome oxidase; NADH2-TR; a-GPDH; b-OHBDH and nonspecific esterase) showed a stronger reactivity in the parietal cells.
