Abstract
Background: Mortality rates in lung cancer patients have not decreased significantly in recent years, even with the implementation of new therapeutic regimens. One of the main problems is that a large proportion of patients present local or distant metastasis at the time of diagnosis. The need for identification of novel biomarkers and therapeutic targets for a more effective management of lung cancer led us to investigate TMPRSS4, a protease reported to promote tumour growth and metastasis. Material and methods: In all, 34 lung cancer cell lines were used to evaluate the TMPRSS4 expression. Cell migration and clonogenic assays, and an in-vivo lung metastasis model were used for functional analysis of the TMPRSS4 downregulation in H358, H441 and H2170 cell lines. The TMPRSS4 expression analysis in normal and malignant lung tissue samples was performed by qPCR. Five different microarray-based publicly available expression databases were used to validate our results and to study prognosis. Results: The TMPRSS4 knock down in H358, H441 and H2170 cells resulted in a significant reduction in proliferation, clonogenic capacity and invasion. A significant (P<0.05) decrease in the lung colonisation and growth was found when mice were injected with TMPRSS4-depleated H358-derived clones, as compared with controls. Expression of TMPRSS4 showed a >30-fold increase (P<0.001) in tumours in comparison with non-malignant samples. Levels in tumours with squamous cell carcinoma (SCC) histology were found to be significantly higher (P<0.001) than those with adenocarcinoma (AC) histology, which was confirmed in data retrieved from the microarrays. Kaplan–Meier curves demonstrated that high levels of TMPRSS4 were significantly associated (P=0.017) with reduced overall survival in the patients with SCC histology, whereas no correlation was found for the AC histology. Conclusion: Our results demonstrate that TMPRSS4 has a role in the lung cancer development. The potential use of TMPRSS4 as a biomarker for lung cancer detection or as a predictor of patient's outcome warrants further investigation.

Abstract
The hemodynamics of septic shock is characterized by a primary reduction of vascular tone, which defines vasoplegia. Septic vasoplegia is due to reduced endogenous production of vasopressin, as well as to the overproduction of vasodilating molecules (nitric oxide, prostacyclin, peroxynitrite and kynurenine) and the opening of ATP-sensitive potassium channels. Treatment is supportive and includes primarily alpha-adrenergic catecholamines. Vasopressin may also be useful, although its place is still controversial. Further agents can improve the vascular responsiveness to catecholamines, most notably low doses hydrocortisone, and, to a lesser extent, activated protein C. Further, innovative therapies, based on recent understanding of pathophysiological mechanisms, might become useful agents to treat septic vasoplegia in the future.

Abstract
The aim of the current study was to determine the possible effects of progestagen oestrous synchronization on vascular endothelial growth factor (VEGF) expression during sheep luteogenesis and the peri-implantation period and the relationship with luteal function. At days 9, 11, 13, 15, 17 and 21 of pregnancy, the ovaries from 30 progestagen treated and 30 ewes cycling after cloprostenol injection were evaluated by ultrasonography and, thereafter, collected and processed for immunohistochemical evaluation of VEGF; blood samples were drawn for evaluating plasma progesterone. The progestagen-treated group showed smaller corpora lutea than cloprostenol-treated and lower progesterone secretion. The expression of VEGF in the luteal cells increased with time in the cloprostenol group, but not in the progestagen-treated group, which even showed a decrease between days 11 and 13. In progestagen-treated sheep, VEGF expression in granulosa-derived parenchymal lobule capillaries was correlated with the size of the luteal tissue, larger corpora lutea had higher expression, and tended to have a higher progesterone secretion. In conclusion, the current study indicates the existence of deleterious effects from exogenous progestagen treatments on progesterone secretion from induced corpora lutea, which correlate with alterations in the expression of VEGF in the luteal tissue and, this, presumably in the processes of neoangiogenesis and luteogenesis.

Abstract
Leishmania mexicana causes localized and diffuse cutaneous leishmaniasis. Patients with localized cutaneous leishmaniasis (LCL) develop a benign disease, whereas patients with diffuse cutaneous leishmaniasis (DCL) suffer from a progressive disease associated with anergy of the cellular response towards Leishmania antigens. We evaluated the production of the interleukins (IL) IL-12, IL-15, IL-18 and tumour necrosis factor-alpha (TNF-alpha) and the expression of the costimulatory molecules CD40, B7-1 and B7-2 in monocytes from LCL and DCL patients, stimulated in vitro with Leishmania mexicana lipophosphoglycan (LPG) for 18 h. LCL monocytes significantly increased TNF-alpha, IL-15 and IL-18 production, and this increase was associated with reduced amounts of IL-12. DCL monocytes produced no IL-15 or IL-18 and showed a decreasing tendency of TNF-alpha and IL-12 production as the severity of the disease increased. No difference was observed in the expression of CD40 and B7-1 between both groups of patients, yet B7-2 expression was significantly augmented in DCL patients. It remains to be established if this elevated B7-2 expression in DCL patients is cause or consequence of the Th2-type immune response that characterizes these patients. These data suggest that the diminished ability of the monocytes from DCL patients to produce cell-activating innate proinflammatory cytokines when stimulated with LPG is a possible cause for disease progression.

Abstract
Cannabis arteritis manifests in cannabis users, independently of tobacco consumption. Around 50 cases were reported in the literature since the first description of this entity in 1960. We report the case of a 36-year-old man, cannabis user, without vascular risk factor who developed digital necrosis on the right foot. The pedal pulses were not palpable. He had no abnormal laboratory findings. Arteriography revealed distal segmental lesions and occlusion of popliteal artery. This arteritis was linked to cannabis use, but the patient did not stop cannabis consumption. His symptoms became even worse and he eventually developed sub-acute ischaemia in his left leg despite vascular treatments. Amputation of the right second toe and of the left leg finally became necessary. Cannabis arteritis is relatively similar to thromboangiitis obliterans in its clinical and arteriographical presentation. A parallelism can be made between the role of tobacco in thromboangiitis obliterans pathogenesis and the role of cannabis in cannabis arteritis. Cannabis use must be searched in young patients presenting with arteriopathy. Cannabis arteritis may indeed represent a frequent cause of juvenile peripheral obstructive arterial disease, but is probably under-diagnosed.

Abstract
Today it is generally accepted that the Bacillus Calmette-Guerin (BCG) vaccine protects against childhood tuberculosis (TB) but this immunity wanes with age, resulting in insufficient protection against adult pulmonary TB. Hence, one possible strategy to improve the protective efficacy of the BCG vaccine would be to boost in adulthood. In this study, using the mouse model, we evaluated the ability of two new TB vaccine candidates, heat-killed BCG (H-kBCG) and arabinomannan-tetanus toxoid conjugate (AM-TT), given intransally in a novel Eurocine adjuvant, to boost a primary BCG-induced immune response and to improve protection. Young C57BL/6 mice were vaccinated with conventional BCG and, 6 months later, boosted intranasally with adjuvanted H-kBCG or AM-TT, or subcutaneously with BCG. Ten weeks after the booster, mice were challenged intravenously with M. tuberculosis (Mtb) strain H37Rv. In spleens, there was a significant reduction of cfu counts in mice boosted with either H-kBCG or AM-TT vaccines compared to the non-boosted BCG-vaccinated mice. None of the boosting regimens significantly reduced bacterial loads in lungs, compared to non-boosted BCG vaccination. However, the extent of granulomatous inflammation was significantly reduced in the lungs of mice that received two of the booster vaccines (AM-TT and conventional BCG), as compared with sham-vaccinated mice. All boosted groups, except for mice boosted with the AM-TT vaccine, responded with a proliferation of spleen T cells and gamma interferon production comparable to that induced by a single BCG vaccination.

Abstract
Arterio-venous fistulae increase the diameter of their feeding artery. It may be advantageous to increase the diameter of the internal thoracic artery before its use for coronary grafting. A fistula applied directly to the internal thoracic artery may compromise its subsequent use as a coronary graft and is technically difficult and invasive. However, in view of the continuity between the internal thoracic artery and the inferior epigastric artery, it is possible to achieve the same effect by constructing a fistula on the latter. The purpose of this work was to determine, in a cadaveric study, the feasibility of carrying out an arterio-venous fistula on the inferior epigastric artery so as to increase the caliber of the internal thoracic artery before coronary grafting. A morphologic study of the inferior epigastric artery and its vein and their relations as well as the feasibility of such a fistula was carried out on 10 cadavers. The epigastric artery measured 12.35+/-1.2 cm in length. Its diameter decreased from its origin towards it termination from 3.16+/-0.26 cm to 1.76+/-0.18 cm. There was a constant connection between the inferior and superior epigastric arteries. This connection was single in 30% of cases, double in 50% and through an anastomotic plexus of more than two vessels in 20%. The mean number of anastomotic connections was 1.8. The epigastric vein was constant with a diameter of 0.75+/-0.06 mm at its origin and only sufficiently large to carry out a fistula at its termination (2.6+/-0.9 mm). In conclusion, this study indicates that it should be relatively simple to create a fistula between the inferior epigastric artery and either the inferior epigastric vein or the external iliac vein.

Abstract
OBJECTIVE Evidence based medicine is becoming popular in all fields of medicine. Through systematic reviews, critical evaluation, and statistical strategies such as meta analysis it aids to take decisions in clinical practice. We revise the information on the treatment of epilepsy found in the main sources of evidence based medicine. DEVELOPMENT After commenting some basic concepts such as systematic review, meta analysis, odds ratio, relative risk and numbers needed to treat, we describe the main primary, secondary and tertiary drug information sources with emphasis on sources of evidence based medicine. Some representative examples are given about the information on treatment of epilepsy found in the main sources of evidence based medicine such as TRIP, DARE, Cochrane Library, clinical practice guidelines, Clinical Evidence or Bandolier. Most clinical trials analyze the efficacy and tolerability of add on new antiepileptic drugs in partial refractory epilepsy. However, we found few trials on efficacy and tolerability of these drugs in monotherapy, in newly diagnosed partial epilepsy, on other types of epilepsy or in children. There are also few trials comparing the new antiepileptic drugs between them or in relation to the old ones. CONCLUSION Treatment of epilepsy is yet an art more than a science because clinical practice decisions depends on therapeutic habits and clinical expertise more than on the results emerging from randomized and controlled clinical trials. Large comparative trials are needed but relevant criteria of efficacy and validated procedures to evaluate quality of life, tolerability or cognitive function outcomes should be used in these trials.

Abstract
A lymphangiosarcoma with metastases was found in a horse that presented with respiratory distress and edema in the ventral thorax and abdomen. The necropsy revealed diffuse edema in the subcutaneous connective tissue. Mediastinal, mesenteric, iliac, and renal lymph nodes were enlarged and white with soft, yellowish necrotic areas. Histologic examination revealed numerous channels and disorganized vessels lined by large polyhedral, polymorphic cells. Tumor metastases were observed in the spleen, lungs, and kidneys. Immunohistochemical evaluation of the tumor cells demonstrated positive staining for factor VIII, vimentin, and keratin. Laminin was scarce, and collagen IV staining was negative, consistent with a discontinuous or absent basement membrane.

Abstract
The objectives of this study were to investigate in the goat uterus the expression of estrogen-alpha (ER alpha) and progesterone receptors (PR) and their relationship to proliferation indices (Ki-67) during peri-implantation on Days 22 to 30 post coitum (pc). Immunohistochemical methods were used to quantify ER alpha and PR for luminal and deep regions of the endometrium and of the myometrium. On Day 22 pc cell proliferation was only observed in the luminal epithelium. On Day 24 pc, high cell proliferation indices were seen in luminal epithelium and proliferation began in the luminal stroma and glands. There was a positive correlation between Ki-67 and total ER alpha score in the luminal epithelium (r = 0.53, P < 0.01). Levels of PR scores were highly correlated with Ki-67 indices in luminal epithelium (r = 0.74, P < 0.01) and stroma (r = 0.70, P < 0.01). No Ki-67 expression was observed in deep glands, stroma or myometrium on any of the days studied. Results indicate that patterns of ER alpha and PR expression differ markedly, and that there was a high correlation between PR expression and cell proliferation in the caprine uterus during the peri-implantation period.

Abstract
The risk of closure of a patent ductus arteriosus in the elderly is high because of the fragility of the aorta and aneurysmal change in the ductus. Stent-grafting has emerged as a method of treatment of pathology of the aorta. We describe a case where this new endovascular technique has been successfully applied for closure of a patent ductus arteriosus in a high-risk patient. It may become part of the armamentarium for this pathology in adults.
