ABSTRACT

El granuloma piógeno es un tumor que tradicionalmente se ha considerado de naturaleza no neoplásica. Es una lesión reactiva a varios estímulos de bajo grado, como ser traumas, fármacos, mala higiene oral, desbalances hormonales, que con el tiempo su estructura se ve modificada, es más común en la cavidad oral. Principalmente se asocia a mujeres sin importar el grupo de edad, debido a un efecto vascular mediado por cambios hormonales. Este reporte de caso tiene como objetivo describir la inusual localización de este tipo de lesión y su tratamiento. Se presenta el caso clínico de una paciente femenina de 17 años de edad quien presenta una lesión nodular de tipo exofítica de consistencia firme y sangrante a la palpación, con un tiempo de evolución de un año, de curso progresivo a nivel de la segunda molar inferior derecha. El diagnóstico definitivo se obtuvo mediante el estudio anatomopatológico dando como resultado una lesión reactiva como ser el granuloma piógeno. Se indicaron exámenes imagenológicos como ser radiografía periapical, radiografía panorámica y hematológicos para su respectivo abordaje quirúrgico que consistió en realizar una biopsia de tipo excisional; al control postquirúrgico se observó una adecuada cicatrización y sin signos de recidiva a los 6 meses de control. Debido a su extraña ubicación se decide documentar y compartir este caso clínico, en el cual se optó por el tratamiento convencional quirúrgico obteniendo una adecuada resolución...(AU)

ABSTRACT

The Coronavirus disease 2019 (COVID-19) outbreak in Ghana is part of an ongoing pandemic caused by the Severe Acute Respiratory Syndrome Coronavirus-2 (SARS-CoV-2). The first two cases of COVID-19 were confirmed in Ghana on 12th March 2020. COVID-19 was consequently declared a Public Health Emergency of National Concern, triggering several response actions, including enhanced surveillance, case detection, case management and contact tracing, closure of borders, suspension of international flights, ban on social gatherings and closure of schools. Preparedness and response plans were activated for implementation at the national, regional, district and community levels. Ghana's Strategic approaches were to limit and stop the importation of cases; detect and contain cases early; expand infrastructure, logistics and capacity to provide quality healthcare for the sick; minimise disruption to social and economic life and increase the domestic capacity of all sectors to deal with existing and future shocks. The health sector strategic frame focused on testing, treatment, and tracking. As of 31st December 2020, a total of 535,168 cases, including 335 deaths (CFR: 0.61%), have been confirmed with 53,928 recoveries and 905 active cases. All the regions have reported cases, with Greater Accra reporting the highest number. The response actions in Ghana have seen highlevel political commitment, appropriate and timely decisions, and a careful balance of public health interventions with economic and socio-cultural dynamics. Efforts are ongoing to intensify non-pharmaceutical interventions, sustain the gains made so far and introduce COVID-19 vaccines to reduce the public health burden of the disease in Ghana

ABSTRACT

Resumen El Bosque Petrificado Piedra Chamana, cerca del pueblo de Sexi en Cajamarca, registra la vegetación de los trópicos de Sudamérica de hace 39 millones de años, la que existió en los inicios de la historia de los bosques tropicales del Nuevo Mundo y antes del levantamiento de los Andes. En este bosque, descubrimientos notables incluyen el manglar del género Avicennia, un género de árboles forestales emergentes (Cynometra), y el segundo dipterocarp conocido del Nuevo Mundo. La importancia de los fósiles se basa en sus circunstancias únicas de preservación, es así como fósiles de plantas y suelos antiguos permiten la reconstrucción detallada del bosque y el medio ambiente en que existieron, contribuyendo con el conocimiento del cambio climático. Los sitios como este bosque fósil son muy vulnerables al disturbio y pérdida de los recursos fósiles. El monitoreo muestra que las actividades humanas y la erosión están teniendo efectos serios y que son necesarias medidas urgentes para su conservación. La importancia de los fósiles para la ciencia, la belleza de esta área de los Andes, y el potencial para la educación y turismo justifican el reconocimiento del Bosque Petrificado Piedra Chamana a nivel internacional. El bosque tropical representado por los fósiles es muy diferente del bosque diverso esclerófilo de hoja ancha que se encuentra actualmente en el sitio. La pérdida del suelo y la erosión del substrato suave y poroso por alteración de la cubierta vegetal son una amenaza para la biota nativa y los fósiles. Por lo tanto, las medidas de conservación necesarias para proteger los fósiles tendrían múltiples beneficios para la ecología del área.


Abstract The Piedra Chamana Fossil Forest, near the village of Sexi in central Cajamarca, records the vegetation of the South American tropics 39 million years ago, early in the New World tropical forests history and before the rise of the present-day Andes. In this fossil forest, notable discoveries have included the mangrove genus Avicennia, a genus of emergent forest trees (Cynometra), and the second dipterocarp known from the New World. The significance of the fossils rests on the unique circumstances of preservation, the detailed reconstruction of the forest and environment that is possible based on the plant fossils and ancient soils, and the importance of this record for the study of climate change. Sites like the fossil forest are particularly vulnerable to disturbance and loss of the fossil resources. Ongoing monitoring shows that human activities and erosion are having serious effects and, conservation measures are urgently needed. The importance of the fossils for science, the beauty of this area of the Andes, and the potential of the site for education and tourism justify recognition of the fossil forest at an international level. The lowland tropical forest represented by the fossils is very different from the diverse broad-leaf sclerophyllous forest or woodland now growing in the area. Soil loss and erosion of the soft, porous volcanic substrate when the vegetation cover is disturbed poses a threat to both the native biota and the fossils. The conservation measures needed at the fossil site would have multiple benefits for the ecology of the region.

ABSTRACT

Background: The roles of Chlamydia trachomatis and Neisseria gonorrhoeae in the aetiology of infertility due to tubal occlusion have been established by various studies. These organisms may lead to pelvic infection by ascending into the upper genital tract through any instrumentation like hysterosalpingography. The objectives were to determine the prevalence of asymptomatic chlamydial and gonorrhoeal infections of the genital tract among women being investigated for infertility referred for hysterosalpingography; the relationship of these infections with tubal pathologies; and if routine endo-cervical screening and prophylactic antibiotics be recommended for these patients.Methods: This was a descriptive cross-sectional study. The study population consisted of consecutive 220 infertile women that met the inclusion criteria for this study. Consent was obtained. Endo-cervical swab was taken for NAAT-PCR for Chlamydia trachomatis and Neisseria gonorrhoeae. Hysterosalpingography was carried out. Data was analyzed using SPSS (version 22).Results: Amongst the 220 women, 9 (4.1%) had asymptomatic chlamydia infection. None had gonorrhoea infection and 211 (95.9%) had none of these two organisms. Forty-eight (21.9%) of the 220 women had bilateral tubal blockage and 9 (18.8%) out of these 48 women had asymptomatic infection with Chlamydia trachomatis.Conclusions: There is a statistically significant association between tubal blockage and chlamydia infection (p = 0.00) [RR 4.31 (3.37-5.50)]. There was no evidence to recommend routine screening/antibiotics considering the low prevalence of microbes and the absence of post-HSG pelvic infection. Results from a multicenter randomized controlled trial will be more representative.

ABSTRACT

There are emerging ethical issues with regards to the use of animals in the early stages of drug discovery for anti-inflammatory and degenerative diseases from natural products using the activity-directed isolation pathways when many compounds (eg > 100) are present in the crude extract or fraction and are to be tested. The above-mentioned is the main reason for proposing the use of the in vitro anti-denaturation (stabilization) effects of heat treated (immunogenic) bovine serum albumin (BSA) as an assay. Current methods used for detecting and isolating a wide range of anti-inflammatory compounds in the early stages of the drug discovery process utilize a large number of animals. When BSA is heated and is undergoing denaturation, it expresses antigens associated to Type III hyper-sensitive reaction and which are related to diseases such as serum sickness, glomerulonephritis, rheumatoid arthritis and systemic lupus erythematosus. Thus, the assay that is being proposed should be applicable to the discovery of drugs for treating the above mentioned diseases and others, once the compounds stabilize the denaturation process.


Actualmente surgen problemas éticos en relación con el uso de animales en las etapas tempranas del descubrimiento de medicamentos anti-inflamatorios y contra enfermedades degenerativas, a partir de productos naturales, usando vías de aislamiento dirigido por actividad, cuando muchos compuestos están presentes (p.ej. > 100) en la fracción o extracto crudo, y deben ser probados. Lo anterior representa la razón principal para proponer el uso de los efectos de la anti-desnaturalización (estabilización) in vitro de la albúmina sérica bovina (inmunogénica) tratada con calor (ASB) como ensayo. Los métodos corrientes usados para detectar y aislar una amplia gama de compuestos anti-inflamatorios en las etapas tempranas del proceso de descubrimiento del medicamento, utilizan un gran número de animales. Cuando la ASB es calentada y sometida a un proceso de desnaturalización, expresa antígenos en relación con la reacción hipersensitiva de tipo III, relacionada a su vez con enfermedades tales como la enfermedad del suero, la glomerulonefritis, la artritis reumatoide, y el lupus sistémico y eritematoso. De este modo, el ensayo que aquí proponemos debe ser aplicable al descubrimiento de medicamentos para el tratamiento de las enfermedades anteriormente mencionadas y otras, una vez que los compuestos estabilicen el proceso de desnaturalización.
