Published: January 2022

Introducción. El compromiso tumoral metastásico del melanoma al tracto genitourinario es frecuente, pero, la metástasis a vejiga es rara, constituye menos del 2% de los casos. Sin embargo, en autopsias realizadas a pacientes con melanoma se ha encontrado metástasis en la vejiga en entre un 18% y un 37% de los casos, lo que la convierte en la segunda en incidencia posterior al adenocarcinoma gástrico. La media de supervivencia suele ser entre 6 - 7.5 meses. El objetivo de este trabajo es presentar el caso de un melanoma metastásico a vejiga, entidad poco frecuente y poco diagnosticada por ser la mayoría de las veces asintomática. Presentación del caso. Paciente femenina de 62 años, con antecedente de melanoma al nivel del primer artejo del pie, con manejo quirúrgico y farmacológico. Consultó por hematuria. La cistoscopia evidenció una lesión única sólida, eritematosa, con necrosis y fácil sangrado y se indicó realizar resección transuretral (RTU). La patología demostró compromiso por melanoma ulcerado metastásico. Se inició manejo de segunda línea (Pembrolizumab) y presentó progresión a miembros superiores y recaída a nivel vesical. La paciente falleció un año después. Discusión. Las metástasis de melanoma al tracto genitourinario son frecuentes, pero las metástasis vesicales aisladas son raras. El tratamiento suele ser RTU de la lesión, cistectomía, quimioterapia y radioterapia. La RTU es curativa para las lesiones restringidas al epitelio, aunque la cistectomía radical suele ser la terapia de elección ante un paciente con un tumor localizado. El Pembrolizumab ha demostrado aumentar la supervivencia. El pronóstico depende del tamaño y profundidad de la invasión. Conclusiones. El compromiso vesical metastásico es poco frecuente y diagnosticado, puede estar presente en pacientes con melanoma, síntomas irritativos urinarios no específicos y hematuria. Suele ser de mal pronóstico, y requiere de manejo quirúrgico asociado a manejo sistémico.

La enfermedad de Chagas es una zoonosis producida por la infección del Trypanosoma cruzi (T. cruzi) (1), cuya principal vía de transmisión es vectorial (2). Esta enfermedad se caracteriza por ser una infección crónica que puede ocasionar daños cardiacos, digestivos y neurológicos irreversibles (3).
En el departamento del Putumayo, de acuerdo con los datos del Sistema de Vigilancia Epidemiológica (SIVIGILA), entre el año 2015 y el 2020, se han notificado 19 casos de Chagas crónico y 4 casos de Chagas agudos (4).
Por este motivo resulta de gran interés compartir con los lectores de la revista MedUNAB la actualización de la distribución geográfica de los triatominos, vectores de la enfermedad de Chagas, y establecer el riesgo epidemiológico que representan para la población Putumayense, donde hay hallazgos de gran importancia porque se identifican especies en municipios y localidades donde antes no se conocían.

The solution to this problem is possible by increasing efficiency while reducing costs as much as possible, which requires optimal design of offshore wind farms.GOAL. Development of model for the technical and economic indicators of offshore wind farms based on configuration data, taking into account the factors of climatic conditions and the topography of the seabed at the site of the planned wind farm location.METHODS. Mathematical modeling using Matlab software environment.RESULTS. The model evaluates the impact of wake and electrical losses in the main components of the electrical system on the operation of an offshore wind farm, and also allows to take into account the influence of the seabed relief on the economic characteristics of wind turbine foundations. The model was tested on the example of calculating two existing offshore wind farms «Horns Rev 1» and «Horn Rev 2» by comparing the calculated indicators of the average annual electricity generation, capacity factor, capital expenditures and normalized cost of electricity with the actual indicators obtained during their operation. The comparison results show slight deviations within 5% of the actual values.CONCLUSION. The model for assessing the technical and economic indicators of offshore wind farms was developed and tested on the basis of data on the wind farm configuration and layout, as well as factors of climatic conditions and terrain. Evaluation of the computational speed showed a sufficiently high efficiency of the algorithm, which allows the model to be applied to optimize large offshore wind farms.

The article addresses the problems of methodical support for establishing the statute of limitations when conducting a forensic document examination, directly affecting the admissibility of an expert’s opinion as evidence in legal proceedings. Establishing the statute of limitations for the execution of documents’ requisites is one of the most demanded tasks when considering all categories of cases – administrative, arbitration, civil, criminal. Analysis of the forensic practice of this type of examination in legal proceedings shows the application of various methods and approaches. Such variety raises questions among both the judicial and legal communities. For example, what existing methods are scientifically substantiated, tested, certified, lead to reliable results, and can be used to solve expert tasks? Which are unsuitable for the use in expert practice, and for what reasons?To confirm the suitability of their author’s developments for forensic examination, individual non-state experts provide various patents and certificates. How legal and permissible is this practice?The article offers a competent analysis of the current situation on the example of the widely used method of “wet copying”

Urban land use is one of the important factors in urban environmental planning and modeling. Recent developments also show that Remote Sensing has been accepted as one of the main tools for information extraction and mapping. Extraction of land use information based on Remote Sensing includes visual interpretation and digital interpretation. This study aims to assess the ability of SAS Planet High Resolution Satellite Imagery in mapping land use, and obtaining information on land use changes in terms of the area and type of land use in the research area in 2010-2018. This research is focused in 3 (three) sub-districts in Kupang City. The reason for choosing the location is because observations show that there are many changes in land use, even areas that should not be used have experienced a touch of development. In addition, there are several educational centers, especially universities located in the area which tend to trigger land use changes. The research method used is survey method and data collection with SAS Planet Satellite Image Interpretation. The method of spatial analysis using GIS is by visual interpretation, digitization and overlay. Visual interpretation, digitization and overlay are used to determine land use changes that occur in the study area. The results in this study indicate that SAS Planet High Resolution Satellite Imagery can be used to identify land use information in Kupang City, because it can display objects more clearly, so that interpretation results can reach 90 percent accuracy and land use change analysis shows that within 8 years (2010-2018) there has been a significant change in land use where the built up land in the form of buildings, settlements and forests/mangroves has increased in area. Along with that, there is a reduction in the area of ​​use of grasslands and shrubs. Conversion of the fields also occurs in a moderate area. there was a significant change in which the highest land change occurred in the use of built-up land (buildings and settlements) and forests/mangroves, each of which experienced an increase of 108.45 ha (3.44 percent), settlements increased by 894.88 ha (27.50 percent) , and forest/mangrove area increased by 167.92 ha (5.16 percent).
