Introducción: El síndrome doloroso regional complejo se caracteriza por hiperalgesia, dolor espontáneo o inducido, y alteraciones sensoriales, tróficas y motoras. Genera una limitación funcional severa y, en ocasiones, se asocia al inicio o la exacerbación del síndrome de túnel del carpo. Objetivo: Caracterizar la relación entre el síndrome de túnel del carpo y el síndrome doloroso regional complejo. Presentación de caso: Se describe el caso de una paciente del sexo femenino, con 54 años y antecedente de Síndrome de túnel del carpo en miembro superior derecho. Este se exacerbó por la aparición de un síndrome doloroso regional complejo secundario a celulitis. Conclusiones: La aparición y la exacerbación aguda del Síndrome de túnel del carpo se deben considerar complicaciones del síndrome doloroso regional complejo para manejar y reducir las secuelas funcionales.

Introduction: Complex regional pain syndrome is characterized by hyperalgesia, spontaneous or induced pain, and sensory, trophic, and motor alterations. It generates severe functional limitation and it is sometimes associated with the onset or exacerbation of carpal tunnel syndrome. Objective: To characterize the relationship between carpal tunnel syndrome and complex regional pain syndrome. Case report: We report the case of a 54-year-old female patient with a history of carpal tunnel syndrome in the right upper limb. This was exacerbated by the appearance of a complex regional pain syndrome secondary to cellulitis. Conclusions: The onset and acute exacerbation of carpal tunnel syndrome should be considered complications of complex regional pain syndrome to manage and reduce functional sequelae.

Optic nerve abnormalities in female-restricted Wieacker-Wolff syndrome by a novel variant in the ZC4H2 gene.

BACKGROUND: Wieacker-Wolff syndrome is an ultra-rare disease with X-linked inheritance characterized by arthrogryposis, intellectual disability, microcephaly, and distal limb muscle atrophy. Ophthalmic abnormalities such as ptosis, strabismus, and oculomotor apraxia have been reported in half of the patients. Wieacker-Wolff syndrome female-restricted (WRWFFR) is an even rarer disease recently used for females with a more severe phenotype. MATERIALS AND METHODS: Clinical geneticist and ophthalmic examination, neuroimaging, and exome sequencing. RESULTS: A 4 years-old girl with developmental and language delay, microcephaly, camptodactyly, digital pads, and arthrogryposis was identified by the clinical geneticist. Ophthalmic examination revealed deep-set eyes, high hyperopic astigmatism in both eyes, and reduced retinal nerve fiber layer thickness measured by optical coherence tomography. Exome sequencing identified a novel, probably pathogenic variant in the ZC4H2 gene NM_018684.3:c.145A>T p. (Lys49*) in heterozygosis. DISCUSSION: WRWFFR is an ultra-rare disease with X-linked inheritance by variants in the ZC4H2 gene. This case reports a girl with a novel nonsense variant in the ZC4H2 gene and a severe phenotype; previous reports have identified WRWFFR in females with large deletions and nonsense mutations which could explain the manifestations in the current case report. A complete ophthalmic examination should be considered in patients with WRWFFR to detect the possibly associated optic nerve involvement and other previously described manifestations such as ptosis and strabismus.

[An unusual association of malakoplakia and adenocarcinoma of the prostate]. / Asociación inusual de malacoplaquia y adenocarcinoma prostático.

Malakoplakia is a chronic inflammatory process caused by a lysosomal defect in bacterial digestion. Although rare, it occurs more frequently in the genitourinary tract and in patients with immune dysfunction. The bladder is the most commonly affected site, although cases have been reported in other organs, including the prostate gland. Clinically, this lesion can be confused with malignant tumours, both on physical examination and imagining techniques. This is particularly pronounced in the prostate, making the differential diagnosis challenging. Histologically, characteristic aggregates of histiocytes with basophilic intracytoplasmic inclusions composed of calcium and iron salts are found. We present a case diagnosed on transrectal biopsy as acinar adenocarcinoma with a Gleason 5 + 5 = 10 score. Prostatectomy revealed an unusual association of diffuse prostate malakoplakia and an area of acinar adenocarcinoma with a Gleason score of 3 + 4 = 7.

Asociación inusual de malacoplaquia y adenocarcinoma prostático / An unusual association of malakoplakia and adenocarcinoma of the prostate

La malacoplaquia es un proceso inflamatorio crónico causado por un defecto lisosomal en la digestión bacteriana. El trastorno, aunque raro, aparece con mayor frecuencia en pacientes con disfunción inmunitaria y en aparato genitourinario. La vejiga es el sitio más comúnmente afectado, aunque se han informado casos con involucro de otros órganos, incluyendo la glándula prostática. Desde una perspectiva clínica, la lesión puede simular tumores malignos durante la exploración física y en estudios de imagen, en particular en próstata, por lo que el diagnóstico diferencial suele ser desafiante. Su expresión morfológica se caracteriza histológicamente por agregados histiocíticos con inclusiones basófilas intracitoplasmáticas, compuestas por sales de calcio y hierro. Se presenta un caso que fue diagnosticado en biopsia transrectal como adenocarcinoma acinar con suma de Gleason 5 + 5 = 10. En la prostatectomía se evidenció la asociación excepcional de malacoplaquia prostática difusa y un foco de adenocarcinoma acinar Gleason 3 + 4 = 7.(AU)

Case Report: Cerebral Phaeohyphomycosis Due to Chaetomium strumarium in a Child with Visceral Heterotaxy Syndrome.

Chaetomium sp. is a mold, member of the phylum Ascomycota. Clinical disease in humans is rare, particularly in children, for which only five cases have been reported. We report a 7-months-old female patient with a diagnosis of visceral heterotaxy syndrome who was admitted to a private center in Mexico. After two episodes of focal myoclonic seizure, a brain magnetic resonance imaging (MRI) revealed a right porencephalic cyst and a right frontal abscess with ventriculitis. Seventy-two hours after temporal abscesses drainage procedure, the culture showed a rapidly growing pale white fungal colony. Sequencing of internal transcribed spacer (ITS) and D1/D2 led to the identification of Chaetomium strumarium. Although Chaetomium sp. is a rare fungal infection in humans, clinicians should consider it as a plausible etiologic agent that can form brain abscess.

Management of seizures in neonates with neonatal encephalopathy treated with hypothermia.

Neonatal encephalopathy (NE) is the most common etiology of acute neonatal seizures - about half of neonates treated with therapeutic hypothermia for NE have EEG-confirmed seizures. These seizures are best identified with continuous EEG monitoring, as clinical diagnosis leads to under-diagnosis of subclinical seizures and over-treatment of events that are not seizures. High seizure burden, especially status epilepticus, is thought to augment brain injury. Treatment, therefore, is aimed at minimizing seizure burden. Phenobarbital remains the mainstay of treatment, as it is more effective than levetiracetam and easier to administer than fosphenytoin. Emerging evidence suggests that, for many neonates, it is safe to discontinue the phenobarbital after acute seizures resolve and prior to hospital discharge.

Measuring oil residence time with GPS-drifters, satellites, and Unmanned Aerial Systems (UAS).

As oil production worldwide continues to increase, particularly in the Gulf of Mexico, marine oil spill preparedness relies on deeper understanding of surface oil spill transport science. This paper describes experiments carried out on a chronic release of crude oil and aims to understand the residence time of oil slicks using a combination of remote sensing platforms and GPS tracked drifters. From April 2017 to August 2018, we performed multiple synchronized deployments of drogued and un-drogued drifters to monitor the life time (residence time) of the surface oil slicks originated from the MC20 spill site, located close to the Mississippi Delta. The hydrodynamic design of the two types of drifters allowed us to compare their performance differences. We found the un-drogued drifter to be more appropriate to measure the speed of oil transport. Drifter deployments under various wind conditions show that stronger winds lead to reduce the length of the slick, presumably because of an increase in the evaporation rate and entrainment of oil in the water produced by wave action. We have calculated the residence time of oil slicks at MC20 site to be between 4 and 28 h, with average wind amplitude between 3.8 and 8.8 m/s. These results demonstrate an inverse linear relationship between wind strength and residence time of the oil, and the average residence time of the oil from MC20 is 14.9 h.

Remote sensing assessment of oil spills near a damaged platform in the Gulf of Mexico.

An oil platform in the Mississippi Canyon 20 (MC-20) site was damaged by Hurricane Ivan in September 2004. In this study, we use medium- to high-resolution (10-30 m) optical remote sensing imagery to systematically assess oil spills near this site for the period between 2004 and 2016. Image analysis detects no surface oil in 2004, but ~40% of the cloud-free images in 2005 show oil slicks, and this number increases to ~70% in 2006-2011, and >80% since 2012. For all cloud-free images from 2005 through 2016 (including those without oil slicks), delineated oil slicks show an average oil coverage of 14.9 km2/image, with an estimated oil discharge rate of 48 to ~1700 barrels/day, and a cumulative oil-contaminated area of 1900 km2 around the MC-20 site. Additional analysis suggests that the detected oil slick distribution can be largely explained by surface currents, winds, and density fronts.

PPIENSENLo: A Novel Mnemonics in Spanish for Alarm Criteria in Secondary Headaches in Children.

We present the first mnemonic in Spanish, "PPIENSENLo," for alarm criteria in secondary headaches in children in order to facilitate their identification, diagnosis, and treatment. A search was performed across different electronic databases for a mnemonics that applied to clinical alarm criteria in secondary headaches in children. None were found in English or Spanish. This tool is perhaps useful both for clinical and teaching purposes.

Schwann Cell Precursor Transplant in a Rat Spinal Cord Injury Model.

BACKGROUND: Differentiation of mesenchymal stem cells into Schwann cell precursors could reverse established lesions and sequelae of medullary transection. OBJECTIVE: The objective of this study was to study the clinical response of mesenchymal stem cell transplantation with Schwann precursor cell transplantation in a rat spinal cord injury model, using motor function and histopathologic studies. MATERIALS AND METHODS: A total of 28 Sprague-Dawley rats were randomly divided among four groups (n = 7 in each): sham group, control group, mesenchymal stem cell transplant group, and Schwann cell precursor transplant group. The surgical procedure was a laminectomy with transection of the spinal cord at the T11 level in the transplant groups and the injury control group. After 1 week, the transplant groups received stem cells directly in the injury site. Hind limb motor function was assessed using the locomotive scale of Basso, Beattie, and Bresnahan. 1 month after transplantation, all specimens were sacrificed to make a histopathologic description of sections taken from the site of injury and where stem cells were transplanted. Mean scores of mobility were compared using analysis of variance (ANOVA) of one factor with 95% reliability between groups and ANOVA of repetitive measures to evaluate evolution in the same group. RESULTS: We observed that the control group had statistically greater mobility than the other groups (p < 0.0001) and that the group with spinal injury without treatment had the lowest mean mobility. The mobility score values from the Schwann cell precursor group were statistically higher than the group treated with mesenchymal stem cells (p < 0.0001). CONCLUSION: Schwann precursor cells had a greater effect on locomotive function than mesenchymal stem cells.

ANÁLISIS DE UN SISTEMA DE COSECHA DE AGUA LLUVIA A PEQUEÑA ESCALA CON FINALIDAD PECUARIA / ANALYSIS OF A SMALL-SCALE WATER HARVEST SYSTEM FOR LIVESTOCK PURPOSES

La demanda global de agua se ha incrementado durante los últimos años debido al crecimiento de la población y a la necesidad de producir mayor cantidad de bienes y servicios. Sumado a esto, el cambio climático ha modificado los patrones del clima de algunas regiones alterando los periodos de sequía y lluvia. Por tal motivo, se proponen sistemas de cosecha y almacenamiento de agua que permitan almacenar los excesos de agua para su posterior uso en los periodos secos, sin que se interrumpa la producción de alimentos. En la altillanura colombiana se evidencian estos efectos del cambio climático, generando pérdidas a los productores de ganado principalmente debido a la escasez hídrica en la época seca. Basados en lo anterior, el presente estudio tiene como objetivos; 1) caracterizar la dinámica de la precipitación del área de estudio con énfasis en la frecuencia e intensidad, 2) determinar el potencial de cosecha de agua del sistema a pequeña escala. Inicialmente se recopiló información en el periodo 2009­2014, de una estación pluviométrica propia de la granja. Asimismo, se calcularon las dimensiones de la infraestructura del sistema de cosecha para determinar su potencial. Los resultados ponen de manifiesto que en la zona se presenta una distribución de lluvias monomodal, donde el periodo de lluvias comprende los meses de abril a octubre y el periodo seco de noviembre a marzo. Por otro lado, el potencial de cosecha de agua de acuerdo a las condiciones del sistema fue de 820 m3/año y el consumo de los vacunos fue de 540 m3/año. En conclusión, el sistema de cosecha es una estrategia de adaptación al cambio climático ya que mitiga sus efectos negativos; además garantiza que los productores a pequeña escala y de regiones con temporalidad climática marcada tengan producción durante todo el año.

The global water demand has increased during the last years due to the growth of the population and the need to produce more goods and services. Added to this, climate change has varied weather patterns in some regions altering periods of drought and rain. For this reason, water harvesting and storage systems that allow storing excess water for later use in dry periods without interrupting food production are proposed. The effects of climate change are evident in the Colombian eastern highlands (the Altillanura), generating losses to livestock producers mainly because of water shortage in the dry season. Based on the above, this study aims 1) to characterize the dynamics of rainfall in the area of study with emphasis on frequency and intensity; 2) to determine the potential of a small-scale water harvesting system. Initially, information was compiled in the period 2009 - 2014 from a rainfall station typical of the farm. Likewise, the dimensions of the harvesting system infrastructure were calculated to determine their potential. The results show that a monomodal distribution of rainfall is present in the area, where the rainy season covers the months from April to October, and the dry season from November to March. On the other hand, the potential water harvesting, according to the system conditions, was 820 m3 / year, and the consumption of cattle was 540 m3 / year. In conclusion, the harvesting system is an adaptation strategy to climate change since it mitigates its potential damage and guarantees that small-scale producers and regions with marked climate temporality continue to produce all year.

[Evaluating language acquisition using the Early Language Milestone (ELM) and Munich developmental scales]. / Evaluación del lenguaje mediante la escala de Early Language Milestone y el método de Múnich.

OBJECTIVE: Evaluating language development by comparing the Munich Development method to the Early Language Milestone scale for identifying both diagnostic tests' agreement and enriching neurodevelopmental consultation. METHODS: The clinical histories of a cohort of 129 children were evaluated, as prematurity is a risk factor for deviation in children's language development. The children had less than 40 weeks gestational age and 0 to 12 months corrected age. They were given both tests between 2008 and 2011. The results from both scales were compared regarding receptive and expressive language and visual response (Early Language Milestone scale) and evaluation of verbal response, vocal play, understanding and expression (Munich scale). Student's T-test was used for comparing means for paired samples. Results: A statistically significant correlation (p<0.05) was found between both tests and between them and corrected age. It was seen that the higher the corrected age, the greater correlation there was between tests. CONCLUSION: The Early Language Milestone and Munich Development scales, regarding their components dealing with language, both represent useful tools for following-up premature children's language development.

Mini-temporal and perilobular approach to facelift: mini-TAPA-facelift.

BACKGROUND: Many people today are looking to preserve their youthful appearance for as long as possible. Current techniques of facial rejuvenation consist of superficial muscular aponeurotic system and/or deep tissue manipulation to relocate the tissues to their former positions. Scars continue to be a limiting factor for many patients who are interested in a facial rejuvenation procedure that has minimal risk and a short recovery period and that truly complies with the term minimally invasive. METHODS: This surgical protocol included a complete medical history, analysis of the degree of aging, and development of a surgical plan. We obtained pre- and postoperative photographic controls for medium- and long-term follow-up and evaluation of results. RESULTS: We treated 67 patients with this minimally invasive technique. The follow-up period ranged from 6 months to 4 years. The results were satisfactory, showing a more harmonious facial appearance. CONCLUSIONS: The mini-temporal and perilobular approach to facelift (mini-TAPA-facelift) is a facial rejuvenation procedure with limited incisions, which allows us to reaffirm the soft tissues of the corners of the eyelids and upper cheek. It also restores the lower midface and the mandibular contour, thus eliminating undesirable jowls. The procedure clearly defines the face from the neck, providing a high level of satisfaction among patients.

Cell-assisted lipotransfer for the treatment of parry-romberg syndrome.

Progressive facial hemiatrophy, also known as Parry-Romberg syndrome, is a progressive and self-limited deformation of the subcutaneous tissue volume on one side of the face that creates craniofacial asymmetry. We present the case of a patient with a five-year history of progressive right facial hemiatrophy, who underwent facial volumetric restoration using cell-assisted lipotransfer (CAL), which consists of an autologous fat graft enriched with adipose-derived stem cells (ASCs) extracted from the same patient. ASCs have the capacity to differentiate into adipocytes. They also promote angiogenesis, release angiogenic growth factors, and some can survive as stem cells. The use of autologous fat as a filler in soft tissue atrophy has been satisfactory in patients with mild and moderate Parry-Romberg syndrome. Currently, CAL has showed promising results in the long term by decreasing the rate of fat reabsorption. The permanence and stability of the graft in all the injected areas has showed that autologous fat grafts enriched with stem cells could be a promising technique for the correction of defects caused by this syndrome.

Adaptive thresholding algorithm based on SAR images and wind data to segment oil spills along the northwest coast of the Iberian Peninsula.

Satellite Synthetic Aperture Radar (SAR) has been established as a useful tool for detecting hydrocarbon spillage on the ocean's surface. Several surveillance applications have been developed based on this technology. Environmental variables such as wind speed should be taken into account for better SAR image segmentation. This paper presents an adaptive thresholding algorithm for detecting oil spills based on SAR data and a wind field estimation as well as its implementation as a part of a functional prototype. The algorithm was adapted to an important shipping route off the Galician coast (northwest Iberian Peninsula) and was developed on the basis of confirmed oil spills. Image testing revealed 99.93% pixel labelling accuracy. By taking advantage of multi-core processor architecture, the prototype was optimized to get a nearly 30% improvement in processing time.
