Síndrome de Leriche, Resolución Quirúrgica / Leriche Syndrome, Surgical Resolution

La enfermedad oclusiva aortoilíaca o el síndrome de Leriche, es una forma de enfermedad arterial periférica, en la que hay una oclusión de las arterias ilíacas de su bifurcación. La manifestación clínica es variable. La claudicación intermitente es la más común; Sin embargo, es una enfermedad generalmente subdiagnosticada debido a su cronicidad y al estilo de vida sedentario de los adultos mayores, que más la presentan. Para el diagnóstico, hay una variedad de opciones, que incluyen pruebas invasivas y no invasivas; La arteriografía es el método de elección. El tratamiento implica cambios en el estilo de vida combinado con el tratamiento conservador o quirúrgico, dependiendo de cada individuo.

Aortoiliac occlusive disease, or Leriche syndrome, is a form of peripheral arterial disease, in which there is an occlusion of the iliac arteries from their bifurcation. The clinical manifestation is variable. Intermittent claudication is the most common; However, it is a disease usually underdiagnosed due to its chronicity and the sedentary lifestyle of older adults, who present it most. For diagnosis, there is a range of options, including invasive and non-invasive tests; arteriography is the method of choice. Treatment involves changes in lifestyle combined with conservative or surgical treatment, depending on each individual

B-Lines Lung Ultrasonography Simulation Using Finite Element Method.

INTRODUCTION: Lung Ultrasonography (LUS) is a fast technique for the diagnosis of patients with respiratory syndromes. B-lines are seen in response to signal reverberations and amplifications into sites with peripheral lung fluid concentration or septal thickening. Mathematical models are commonly applied in biomedicine to predict biological responses to specific signal parameters. OBJECTIVE: This study proposes a Finite-Element numerical model to simulate radio frequency ultrasonic lines propagated from normal and infiltrated lung structures. For tissue medium, a randomized inhomogeneous data method was used. The simulation implemented in COMSOL® used Acoustic Pressure and Time-Explicit models, which are based on the discontinuous Galerkin method (dG). RESULTS: The RF signals, processed in MATLAB®, resulted in images of horizontal A-lines and vertical B-lines, which were reasonably similar to real images. DISCUSSION: The use of inhomogeneous materials in the model was good enough to simulate the scattering response, similar to others in the literature. The model is useful to study the impact of the lung infiltration characteristics on the appearance of LUS images.

Occurrence records and metadata for sand flies (Diptera, Psychodidae, Phlebotominae) collected in the lands of indigenous people in the Brazilian Amazon.

To contribute to knowledge of the epidemiology of American cutaneous leishmaniasis (ACL) among indigenous people living in sylvatic regions, we studied the sand fly fauna collected in areas of disease transmission in the Brazilian Amazon. Here we report two datasets comprising occurrence data for sand flies from the Suruwaha Indigenous Land in the state of Amazonas collected in 2012-2013, and the Wajãpi Indigenous Land in the state of Amapá collected in 2013-2014. Sand flies were collected using unbaited CDC-like light traps at various sites within each study area and were identified to either genus or species-level by taxonomists with expertise in Amazonian fauna. A total of 4,646 records are reported: 1,428 from the Suruwaha and 3,218 from the Wajãpi. These records will contribute to a better understanding of ACL transmission dynamics, as well as the distribution of insect vectors, in these areas.

Introduction: Pneumonia associated with mechanical ventilation (PAMV) is one of the most common healthcare-associated infections in intensive care units (ICU). Recent re- search has focused on the fulfillment of nursing care as a process, leaving aside elements related to the structure of the units, or the result of care. Objective: Design and validate the instrument for auditing compliance with the PAMV prevention protocol in an ICU. Methods: Observational, analytical study, with two measurements, carried out in an ICU of a Regional Hospital in south of Mexico City, with 360 observations on non-pharmacological prevention measures in the ICU to prevent PAMV. In the elaboration of the instrument, documentary sources were selected, of recommendations by level of evidence were extracted, and process of the validation was carried out by a panel of experts. Results: Recommendations were obtained with high levels of evidence, adjustments were made to the instrument during its subsequent creation. The application time of the instrument ranges from 25 to 30 minutes. The Kuder Richardson 20 test was applied as an internal consistency index with a value of 0.878 in a pilot test and in a final application of 0.853, associations were found between the dimensions of the instrument and similar statistically significant intra-observer responses. No underlying dimensions were obtained from the exploratory factor analysis. Conclusions: The instrument presented desirable psycho- metric characteristics that support the reliability of its measurement; after cultural adjustment, its application in audit processes and improvement projects in intensive care units is considered viable, due to its easy application, exhaustive- ness and closeness to observe the evaluation model of quality of health care.

Social media, advertising, and internet use among general and bariatric surgeons.

INTRODUCTION: The use of the internet and technology has increased, and its implication with medicine is inevitable. Along with these technologies, social media platforms have changed the interaction between peers, forcing an evolution on medical activities and patient relationship. There is no clear information on how surgeons interact with these platforms within their daily practice. METHODS: A transverse study with a survey obtained from general and bariatric surgeons from Mexico was performed, aimed to gather information about social media platforms use (Facebook, Instagram, Twitter, and LinkedIn). Personal, professional, academic, and marketing activities were analyzed and compared between general and bariatric surgeons. Secondly, the same analysis was performed in younger participants. Other variables were also analyzed, such as type of marketing and monthly budget. RESULTS: We obtained 523 surveys (84.1% general and 15.8% bariatric surgeons), where male gender comprised 86.4%. Almost a third considered social media as an important tool. In 53% of the cases, Facebook was preferred for professional activities; Twitter was the second most used. Bariatric surgeons were younger, used all platforms more frequently, and preferred Facebook for every activity. They also invested more in publicity, and showed wider marketing methods than general surgeons. CONCLUSION: There is an important awareness of internet and social media use among general and bariatric surgeons. Facebook leads the activities for both specialties (personal, professional, academic, and marketing), but bariatric surgeons are significantly more involved; additionally, there are more marketing strategies and investment among them.

Comparative Analysis of the Effectiveness of the Topical Administration of Benzocaine and EMLA® on Oral Pain and Tactile Sensitivity.

OBJECTIVES: To compare the effectiveness of the topical administration of benzocaine and EMLA on oral pain and tactile sensitivity. MATERIALS AND METHODS: A randomized, double-blind, split-mouth clinical trial was carried out with 20 volunteers. The sensorial and quantitative tests were applied before the contact with topical anesthetic and after the application. RESULTS: In the superficial tactile perception test, when we compared each group singly, there were statistically significant values in the decrease of superficial tactile perception when compared to the moment prior to the application of anesthetic agents. For the sensitivity to mechanical pain, no statistical significant difference was observed at evaluated times. In the needle penetration test, in an intergroup analysis, we found a decrease in the pain sensitivity to needle penetration at 5 min (p=0.053) and at 10 min (p=0.019) after the contact of the anesthetic drug with the oral mucosa. CONCLUSION: The application of topical anesthetic drugs reduces the discomfort associated with this procedure, mainly until the first 10 minutes. Only the needle penetration sensitivity test showed sufficient sensitivity to reveal a difference in the anesthetic effect between EMLA and benzocaine. This trial is registered with RBR-2N2GSW.

CAPN3, DCT, MLANA and TYRP1 are overexpressed in skin of vitiligo vulgaris Mexican patients.

Vitiligo is a disorder causing skin depigmentation, in which several factors have been proposed for its pathogenesis: Environmental, genetic and biological aspects of melanocytes, even those of the surrounding keratinocytes. However, the lack of understanding of the mechanisms has complicated the task of predicting the development and progression. The present study used microarray analysis to characterize the transcriptional profile of skin from Vitiligo Vulgaris (VV) patients and the identified transcripts were validated using targeted high-throughput RNA sequencing in a broader set of patients. For microarrays, mRNA was taken from 20 skin biopsies of 10 patients with VV (pigmented and depigmented skin biopsy of each), and 5 biopsies of healthy subjects matched for age and sex were used as a control. A signature was identified that contains the expression pattern of 722 genes between depigmented vitiligo skin vs. healthy control, 1,108 between the pigmented skin of vitiligo vs. healthy controls and 1,927 between pigmented skin, depigmented vitiligo and healthy controls (P<0.05; false discovery rate, <0.1). When comparing the pigmented and depigmented skin of patients with vitiligo, which reflects the real difference between both skin types, 5 differentially expressed genes were identified and further validated in 45 additional VV patients by RNA sequencing. This analysis showed significantly higher RNA levels of calpain-3, dopachrome tautomerase, melan-A and tyrosinase-related protein-1 genes. The data revealed that the pigmented skin of vitiligo is already affected at the level of gene expression and that the main differences between pigmented and non-pigmented skin are explained by the expression of genes associated with pigment metabolism.

Deltamethrin resistance in Aedes aegypti results in treatment failure in Merida, Mexico.

The operational impact of deltamethrin resistance on the efficacy of indoor insecticide applications to control Aedes aegypti was evaluated in Merida, Mexico. A randomized controlled trial quantified the efficacy of indoor residual spraying (IRS) against adult Ae. aegypti in houses treated with either deltamethrin (to which local Ae. aegypti expressed a high degree of resistance) or bendiocarb (to which local Ae. aegypti were fully susceptible) as compared to untreated control houses. All adult Ae. aegypti infestation indices during 3 months post-spraying were significantly lower in houses treated with bendiocarb compared to untreated houses (odds ratio <0.75; incidence rate ratio < 0.65) whereas no statistically significant difference was detected between the untreated and the deltamethrin-treated houses. On average, bendiocarb spraying reduced Ae. aegypti abundance by 60% during a 3-month period. Results demonstrate that vector control efficacy can be significantly compromised when the insecticide resistance status of Ae. aegypti populations is not taken into consideration.

Pulmonary extraskeletal myxoid chondrosarcoma: A case report and literature review.

BACKGROUND: Extraskeletal myxoid chondrosarcoma (EMC) accounts for the 3% of all soft tissue sarcomas and it's categorized as a tumour of uncertain differentiation. This entity has shown to have the recurrent balanced chromosomal translocation t(9;22) (q22;q12.2), which leads to the oncogenic fusion gene EWSR1-NR4A3. This sarcoma usually presents as a slow growing, palpable mass in the extremities. EMC arising from the lung is extremely infrequent. We report one case of pulmonary extraskeletal mixoid chondrosarcoma and a review of the world literature. CASE REPORT: A 69-year-old male patient presented with intermittent hemoptysis for the last 6 months. A PET/CT scan showed a hypermetabolic solid mass with lobulated borders of approximately 29×26mm in the inferior right lobe. We performed a right thoracotomy with inferior lobectomy and lymphadenectomy of levels VII, VIII, X, and XI levels. The neoplasm was constituted by cords of small cells with small round nucleus and scarce cytoplasm immerse in an abundant myxoid matrix. The immunophenotype was positive for MUM-1, CDK4, MDM2, and showed focal expression for S-100 protein and CD56. The final pathology report revealed a pulmonary extraskeletal mixoid chondrosarcoma. No further surgical interventions or adjuvant therapies were needed. CONCLUSION: EMC is an intermediate-grade neoplasm, characterized by a long clinical course with high potential for local recurrence and distant metastasis. Treatment for EMC is surgical and non-surgical treatment is reserved for recurrence or metastatic disease. Pulmonary extraskeletal myxoid chondrosarcoma is a rare neoplasm with only isolated case reports found in the literature.

Yellow fever impact on brown howler monkeys (Alouatta guariba clamitans) in Argentina: a metamodelling approach based on population viability analysis and epidemiological dynamics

In South America, yellow fever (YF) is an established infectious disease that has been identified outside of its traditional endemic areas, affecting human and nonhuman primate (NHP) populations. In the epidemics that occurred in Argentina between 2007-2009, several outbreaks affecting humans and howler monkeys (Alouatta spp) were reported, highlighting the importance of this disease in the context of conservation medicine and public health policies. Considering the lack of information about YF dynamics in New World NHP, our main goal was to apply modelling tools to better understand YF transmission dynamics among endangered brown howler monkey (Alouatta guariba clamitans) populations in northeastern Argentina. Two complementary modelling tools were used to evaluate brown howler population dynamics in the presence of the disease: Vortex, a stochastic demographic simulation model, and Outbreak, a stochastic disease epidemiology simulation. The baseline model of YF disease epidemiology predicted a very high probability of population decline over the next 100 years. We believe the modelling approach discussed here is a reasonable description of the disease and its effects on the howler monkey population and can be useful to support evidence-based decision-making to guide actions at a regional level.

[Control of Aedes aegypti breeding sites with the program Recicla por tu bienestar in Merida, Mexico]. / Control de criaderos de Aedes aegypti con el programa Recicla por tu bienestar en Mérida, México.

OBJECTIVES: To determine the importance of Ae. aegypti breeding-sites in Merida;to evaluate the impact of Recicla por tu bienestar (RxB, a recycling program) on the reduction of breeding sites and the perception of participants. MATERIALS AND METHODS: The relative importance for pupae production of the different types of breeding-sites was determined. Pre-and post-RxB entomological surveys were performed in participant neighborhoods to evaluate the impact on total containers and positive breeding-sites. A survey on the perception of participating people about dengue prevention and control and RxB was applied. RESULTS: Buckets/pots and "small diverse items" were the most important breeding-sites. RxB had a significant impact in the reduction of total containers (IRR = 0.74), positive containers (IRR = 0.33) and the risk of a house being positive for Ae. aegypti (OR = 0.41). All the interviewed participants referred RxB as needed and most consider it useful. CONCLUSIONS: RxB should be considered as a good practice for the dengue vector control.

Intestinal intussusception in adults: tomographic findings and report of two cases.

Intestinal intussusception is infrequent in adults. Unlike what happens in kids, it shows a demonstrable etiology in most cases: polyps, lipomas, hamartomas, malignancies, etc. Among diagnostic methods, CT scan is the study that yields the best results for the diagnosis, giving forth pathognomonic signs and favoring therapeutic decision-making. Two cases of intestinal intussusception in adults secondary to benign pathology are analyzed, stressing mainly the tomographic findings and some considerations about therapeutic decision-making based on tomographic results.
