Abstract
Thermography enables non-invasive, accessible, and easily repeated foot temperature measurements for diabetic patients, promoting early detection and regular monitoring protocols, that limit the incidence of disabling conditions associated with diabetic foot disorders. The establishment of this application into standard diabetic care protocols requires to overcome technical issues, particularly the foot sole segmentation. In this work we implemented and evaluated several segmentation approaches which include conventional and Deep Learning methods. Multimodal images, constituted by registered visual-light, infrared and depth images, were acquired for 37 healthy subjects. The segmentation methods explored were based on both visual-light as well as infrared images, and optimization was achieved using the spatial information provided by the depth images. Furthermore, a ground truth was established from the manual segmentation performed by two independent researchers. Overall, the performance level of all the implemented approaches was satisfactory. Although the best performance, in terms of spatial overlap, accuracy, and precision, was found for the Skin and U-Net approaches optimized by the spatial information. However, the robustness of the U-Net approach is preferred.

Abstract
In this paper, we present methodology and tools for creating custom three-dimensional anatomical atlases for medical education based on web technologies and open-source software. Traditional medical anatomy education has relied on printed anatomical atlases, in-person lectures, and anatomical dissection. This traditional approach underserves populations in need due to high cost, lack of availability of materials, and a limited of trained educators. Open and free online anatomical atlases developed by an international community of experts help remedy these shortcomings, more fully addressing the sustainable development goals of quality education and good health at a global scale. We have developed a web application, the Atlas Assembly Tool, that assists medical professionals in assembling atlases for open dissemination throughout the world. Our tool aims to complement existing open source medical projects such as 3D Slicer and the Open Anatomy Browser to provide a pipeline from original medical image data to web-browsable atlases suitable for medical education. Our development is an integral part of the European INTERREG MACbioIDi project, promoting sustainable development through technology-based medical education and training in close collaboration with partners in Europe, Africa and the United States.

Abstract
The population of Mobula birostris ("giant manta ray") found in the waters of northern Peru and Ecuador is believed to be the largest in the world (Harding Beirwagen, 2009). This species is considered to be the largest within the group of manta rays, as they attains at least 670 cm disc width (reported to 910 cm) (White et al., 2006) and there is a record of an individual weighing 2000 kg (Kunjipalu Boopendranath, 1981). This species is ovoviviparous (matrotrophic viviparious) (Herbert, 2012). A single pup follows a gestation period of approximently one year, (Marshall et al., 2008, Mendonça et al., 2012). Sucessive pregnancies are speculated to be separated by a refactory period of two or more years (Mendonça et al., 2012). The objective of this study is to record the measurements of a M. birostris fetus of a female caught accidentally in the region of Tumbes, Peru. This is the first record of morphological and morphometric data regarding a manta fetus in Peru.

Abstract
In the developing world, most patients with hepatocellular carcinoma present with advanced-stage disease, considered to be incurable based on current therapeutic algorithms. Here, we demonstrate that curative liver resection is achievable in a portion of Peruvian patients not addressed by these treatment algorithms. We conducted a retrospective cohort study of 253 hepatocellular carcinoma patients that underwent a curative hepatectomy between 1991 and 2011 at the National Cancer Institute of Peru. The median age of the cohort was 36 years, and merely 15.4% of the patients displayed cirrhosis. The average tumor size was over 14 cm in diameter, resulting in 76.3% of major hepatectomies performed. The 5- and 10-year survival probability estimates were 37.5% and 26.2%, respectively. Age (>44 vs. ≤44 years old; P = 0.005), tumor size (>10 cm vs. ≤10 cm in diameter; P = 0.009), cirrhosis (P < 0.001), satellite lesions (P < 0.001), macroscopic vascular invasion (P < 0.001), allogeneic blood transfusion (P = 0.011), and spontaneous rupture of the tumor (P = 0.006) were independent predictive factors for prognosis. Hepatocellular carcinomas in Peru are characterized by a distinct clinical presentation with notable features compared with those typically described throughout relevant literature. Despite a large number of advanced-stage hepatocellular carcinomas, the outcomes of liver resection observed in the present study were in good standing with the results previously described in other series. It thus appears that staging systems and associated therapeutic algorithms designed for use in the developed world remain inadequate in certain populations, especially in the context of Peruvian patients. Our findings suggest that clinicians in the developing world should reconsider management guidelines pertaining to hepatocellular carcinoma. Indeed, we hypothesize that, in developing countries, a strict adherence to these therapeutic algorithms might create a selection bias resulting in the dismissal of patients who could eventually be treated.

Abstract
Grafts from split livers (SLs) constitute an accepted approach to expand the donor pool. Over the last 5 years, most Argentinean centers have shown significant interest in increasing the use of this technique. The purpose of this article is to describe and analyze the outcomes of right-side grafts (RSGs) and left-side grafts (LSGs) from a multicenter study. The multicenter retrospective study included data from 111 recipients of SL grafts from between January 1, 2009 and December 31, 2013. Incidence of surgical complications, patient and graft survival, and factors that affected RSG and LSG survival were analyzed. Grafts types were 57 LSG and 54 RSG. Median follow-up times for LSG and RSG were 46 and 42 months, respectively. The 36-month patient and graft survivals for LSG were 83% and 79%, respectively, and for RSG were 78% and 69%, respectively. Retransplantation rates for LSG and RSG were 3.5% and 11%, respectively. Arterial complications were the most common cause of early retransplantation (less than 12 months). Cold ischemia time (CIT) longer than 10 hours and the use of high-risk donors (age ≥ 40 years or body mass index ≥ 30 kg/m2 or ≥ 5 days intensive care unit stay) were independent factors for diminished graft survival in RSG. None of the analyzed variables were associated with worse graft survival in LSG. Biliary complications were the most frequent complications in both groups (57% in LSG and 33% in RSG). Partial grafts obtained from liver splitting are an excellent option for patients in need of liver transplantation and have the potential to alleviate the organ shortage. Adequate donor selection and reducing CIT are crucial for optimizing results.

Abstract
Yellow leaf disease, caused by Sugarcane yellow leaf virus (SCYLV), is widespread around the world but very little information is available on this viral disease in Argentina. Therefore, the aims of the study were to assess the presence of SCYLV, analyze its distribution in the main sugarcane production areas of Argentina, characterize the virus, and determine histological alterations caused by its presence. For this purpose, 148 sugarcane samples with and without symptoms were collected in 2011 and 2012 from the province of Tucumán. One additional sample was collected in Salta, a different geographical, agroecological, and producing region. Results showed that SCYLV is widely distributed in commercial varieties of sugarcane throughout Tucumán in both symptomatic and asymptomatic leaves. A low but statistically significant positive correlation with virus detection and disease symptoms was found. BRA-PER was the only genotype detected by reverse-transcription polymerase chain reaction and sequence analysis of the SCYLV capsid protein gene. SCYLV-positive samples showed high starch levels in bundle sheath cells, whereas the asymptomatic ones, probably in an early stage of infection, were found to contain more chloroplasts. Symptomatic noninfected samples presented crystal formation probably associated with phytoplasma infection.

Abstract
OBJECTIVES Identify prognostic factors associated to total or proximal gastrectomy with or without splenectomy and / or distal pancreatectomy in patient with proximal gastric cancer. Evaluate the frequency of lymph node metastasis to the hilum and splenic artery, postoperative morbidity and mortality and the impact of lymphadenectomy of group 10 and 11 on long term survival. MATERIALS AND METHODS We performed an observational, descriptive, longitudinal and retrospective study analyzing patients with diagnostic of proximal third gastric adenocarcinoma subjected to total or proximal gastrectomy with or without splenectomy or distal pancreatectomy in the service of Abdomen of the Instituto Nacional de Enfermedades Neoplásicas between 1990 and 2005. Overall survival for each of the groups was calculated using the Kaplan-Meier method, prognostic factors were evaluated using univariate and multivariate analysis. RESULTS We studied 219 patients with proximal third gastric adenocarcinoma (cardias and bottom), of wich, according to inclusion criteria, only qualify 129 (N=129): 22 (17.1%) were treated by gastrectomy alone, 79 (61.2%) gastrectomy associated witch splenectomy and 28 (21.7%) gastrectomy with distal pancreatosplenectomy, constituting three treatment groups. We compared the survival of each group and each factor analyzed, determining the following prognostic factors: lymph node metastasis (N2-N3), degree of differentiation, undifferentiated tumors and Borrmann III and IV tumors. Neither splenectomy or distal pancreatectosplenectomy improved survival compared to the gastrectomy alone. The morbidity and mortality was higher in patients with more aggressive but more aggressive surgery without significant value. CONCLUSIONS The number of nodes removed in patients who had pancreatosplenectomy and /or splenectomy was higher, however, had no impact on survival at 5 years.

Abstract
Introduction Hepatitis A virus (HAV) infection is a vaccine-preventable disease. The most severe complication in children is fulminant hepatic failure (FHF), estimated to occur in 0.4% of cases; patients with FHF often require a liver transplant (LT). Following another outbreak of HAV infection in Argentina during 2003–2004, a one-dose HAV universal immunization (UI) program was started in 2005, resulting in a reduction in the incidence of HAV infection. We have investigated the impact of HAV UI on the trends in the occurrence of FHF and LT in children. Methods All pediatric cases of FHF admitted to four pediatric centers in Buenos Aires during March 1993–July 2005 were retrospectively reviewed, and data of cases during August 2005–December 2008 were collected. Information about demography, HAV infections and vaccination status, diagnostic data for FHF using the Pediatric Acute Liver Failure criteria, clinical laboratory results, encephalopathy, the severity of liver disease using the Pediatric End Stage Liver Disease score, assessment of patients on the LT waiting list using King’s College Criteria for LT, treatment given for FHF (pre- and post-transplant), and clinical outcome were collected using a case report form. The frequency and outcomes of HAV-associated FHF and LT cases before and after UI were analyzed. Results During the pre-immunization period, March 1993–July 2005, 54.6% (N = 165) of FHF cases were caused by HAV; HAV-associated FHF cases peaked during 2003–2004. During the post-immunization period, August 2005–December 2008, only 27.7% (N = 18) of FHF cases were caused by HAV infection; only one of these patients had received the HAV vaccine (one dose only). The number of HAV-associated FHF cases decreased from 2005, and no cases were reported from November 2006–December 2008. Multivariate analyses showed that the association of FHF with HAV infection rather than other etiologies decreased with increasing age (P = 0.03), UI against HAV (P = 0.002), and anti-actin antibodies (P = 0.002), and increased with increasing weight (P = 0.0004). Conclusions The number of children with HAV-associated FHF in Argentina has strongly decreased since the initiation of the UI program. Further monitoring is required to confirm the long-term health and economic benefits of UI against HAV infection.

METHODS In an observational, descriptive and retrospective case series design, 148 patiens' files who underwent gastrectomy for stomach adenocarcinoma in the National Cancer Institue of Lima during 1990 and 2000, have been reviewed looking for the development of gallbladder stones. RESULTS A total de 148 patients were involved in this study. 29 of them (19.6%) develop gallbladder stones during the (x years of) follow up vs 119 (80.9%) . The mean age ot the 29 patients with gallbladder stones were 59.9 years ans 18 of them were female and 11 male.\The mean time of develop gallbladder stones was 3.1 years.According to the type of surgery, 14 patient wiht gallbladder stones underwent to subtotal gastrectomy and 15 to total gastrectomy. CONCLUSIONS The frecuency of gallbladder stones post gastrectomy in this study was 19.6%. The mean time of the develop and diagnosis of litiasis was 3.1 years.To perform the colecistectomy at the same time of the gastrectomy could be an important decision in patients with high risk of gallstones and gallbladder cancer.We need furthermore studies to have conclusions about the risk factors.

Abstract
Most mutation-related aberrant splicing occurs in the conserved splice-acceptor and -donor sites and some exonic mutations also affect splicing. We identified and characterized a point mutation (380C>T) in a Spanish patient (GK25) with mitochondrial acetoacetyl-CoA thiolase (T2) deficiency. GK25 is a homozygote of 380C>T, which activates a cryptic splice-acceptor site 5 bases downstream from 380C>T within exon 5, causing aberrant splicing in 94% of transcripts. The aberrant splicing results in a 17-amino acids deletion, including the active-site 126Cys. The 380C>T mutation also results in A127V mutation in 6% of transcripts. Transient expression analysis showed that the A127V mutation did not retain T2 activity, indicating that 380C>T was a null mutation. Although this cryptic splice site has a higher Shapiro and Senapathy's score (86) in even a normal sequence than the authentic splice-acceptor site of intron 4 (78), it is not used in normal controls. While the 380C>T mutation increases the score slightly (90), the cryptic splice site is used in almost all transcripts in GK25 fibroblasts. This is an example in which a point mutation activates a cryptic splice-acceptor site motif that is used preferentially over the upstream authentic splice site.

Abstract
The theoretical advantages of the piggyback technique over conventional orthotopic liver transplantation are as follows. (1) Continuous venous decompression during the anhepatic phase is provided without venovenous bypass. (2) Warm ischemia time can be shortened because there is no need for the infrahepatic vena cava anastomosis. The following report is a review of the authors' experience with this method in children during the past year at their institution. Analyses of intraoperative hemodynamics and blood loss, postoperative renal function, patient and graft survival, and length of hospital stay have shown excellent results. There were no intraoperative deaths, and causes of death and graft loss were not related to the technique. The authors conclude that children who undergo liver transplantation can be very satisfactorily managed with the piggyback operation, and this technique may be more advantageous than the conventional method.
