Foundries in manufacturing plants are characterized by hazardous working conditions. The paper makes an assessment of industrial health hazards, identifies groups of diseases dominant among the examined individuals. It is clear that gastrointestinal diseases make the largest percentage. The effect of destabilizing industrial factors that lead to the intestinal biome restructuring, help reduce the dominant microorganism’s group and increase opportunistic flora has been determined. The severity of this indicator correlates with professional working experience. Along with the fecal matter bacterial flora of the examined people, the protozoa that belong to the parasitic group (blastocysts, lamblia, amoeba) were identified, and Blastocystis spp. has the largest proportion. The biological properties of blastocysts were studied exemplified by anticarnosine activity (AcrA), which allows them to colonize the intestinal mucous membranes and helps displace obligate symbiotes against the decrease in the overall resistance of the macroorganism. The data obtained make it possible to forecast human health state under the conditions of anthropogenic-disturbed territories and plan measures to improve and protect workers’ health.

Abstract Introduction Fecaloma is a large mass of organized hardened feces causing impaction, usually in rectum and sigmoid colon. Medical management usually entails digital evacuation, use of clearance enema, and oral laxatives. We report two patients managed successfully with colonoscopic instillation of Coca-Cola and review the literature. Case Report Patient 1: A 37-year-old male presented with firm, nontender, pitting mass over lower abdomen for 2 months and inability to pass stool for 1 month. Per-rectal examination and imaging confirmed presence of solid stool with gross distension of rectum and sigmoid colon. Attempts at clearance of stool with conventional methods were unsuccessful. At colonoscopy, 4 L of Coca-Cola was instilled into descending and sigmoid colon, leading to evacuation of 10 L of fragmented and liquid stool.Patient 2: A 72-year-old diabetic lady presented with constipation and tender, firm pelvic mass extending till mid-abdomen for 6 months. Per-rectal examination revealed presence of hard stool. Imaging confirmed large amount of fecal matter in dilated rectum, sigmoid, and descending colon. Attempts at evacuating stool with digital evacuation, sodium phosphate enema, and oral polyethylene glycol were unsuccessful. At colonoscopy, two sittings of instillation of 990 mL of Coca-Cola Light each were done into sigmoid colon over 2 days, resulting in clearance. Conclusion Colonoscopic instillation of Coca-Cola may be effective in evacuation of large fecaloma from rectum, sigmoid, and descending colon when refractory to use of conventional methods like digital disimpaction, rectal enema, and oral laxatives.

Abstract Background: Terrorist attacks are growing in complexity, increasing concerns around the use of chemical, biological, radiation, and nuclear (CBRN) agents. This has led to increasing interest in Counter-Terrorism Medicine (CTM) as a Disaster Medicine (DM) sub-specialty. This study aims to provide the epidemiology of CBRN use in terrorism, to detail specific agents used, and to develop training programs for responders. Methods: The open-source Global Terrorism Database (GTD) was searched for all CBRN attacks from January 1, 1970 through December 31, 2018. Attacks were included if they fulfilled the terrorism-related criteria as set by the GTD’s Codebook. Ambiguous events or those meeting only partial criteria were excluded. The database does not include acts of state terrorism. Results: There were 390 total CBRN incidents, causing 930 total fatal injuries (FI) and 14,167 total non-fatal injuries (NFI). A total of 347 chemical attacks (88.9% of total) caused 921 FI (99.0%) and 13,361 NFI (94.3%). Thirty-one biological attacks (8.0%) caused nine FI (1.0%) and 806 NFI (5.7%). Twelve radiation attacks (3.1%) caused zero FI and zero NFI. There were no nuclear attacks. The use of CBRN accounted for less than 0.3% of all terrorist attacks and is a high-risk, low-frequency attack methodology. The Taliban was implicated in 40 of the 347 chemical events, utilizing a mixture of agents including unconfirmed chemical gases (grey literature suggests white phosphorous and chlorine), contaminating water sources with pesticides, and the use of corrosive acid. The Sarin gas attack in Tokyo contributed to 5,500 NFI. Biological attacks accounted for 8.0% of CBRN attacks. Anthrax was used or suspected in 20 of the 31 events, followed by salmonella (5), ricin (3), fecal matter (1), botulinum toxin (1), and HIV (1). Radiation attacks accounted for 3.1% of CBRN attacks. Monazite was used in 10 of the 12 events, followed by iodine 131 (1) and undetermined irradiated plates (1). Conclusion: Currently, CBRN are low-frequency, high-impact attack modalities and remain a concern given the rising rate of terrorist events. Counter-Terrorism Medicine is a developing DM sub-specialty focusing on the mitigation of health care risks from such events. First responders and health care workers should be aware of historic use of CBRN weapons regionally and globally, and should train and prepare to respond appropriately.

This protocol is for isolation of bacteriophages from fecal matter. It is based on the protocol used for the COPSAC10 cohort and was originally described by Ling Deng in doi:10.3390/v11070667. Extraction is performed using centrifugation and ultrafiltration to isolate viral particles and get rid of contaminants.

Despite multiple screening techniques, including colonoscopy, flexible sigmoidoscopy, radiological imaging, and fecal occult blood testing, colorectal cancer remains a leading cause of death. As these techniques improve, their sensitivity to detect malignant lesions is increasing; however, detection of precursor lesions remains problematic and has generated a lack of general acceptance for their widespread usage. Early detection by an accurate, noninvasive, cost-effective, simple-to-use screening technique is central to decreasing the incidence and mortality of this disease. Recent advances in the development of molecular markers in faecal specimens are encouraging for its use as a screening tool. Genetic mutations and epigenetic alterations that result from the carcinogenetic process can be detected by coprocytobiology in the colonocytes exfoliated from the lesion into the fecal matter. These markers have shown promising sensitivity and specificity in the detection of both malignant and premalignant lesions and are gaining popularity as a noninvasive technique that is representative of the entire colon. In this paper, we summarize the genetic and epigenetic fecal molecular markers that have been identified as potential targets in the screening of colorectal cancer.

CARACTERES EPIDÉRMICOS FOLIARES DE PLANTAS ORNAMENTALES, TÓXICAS PARA ANIMALES DOMÉSTICOS. LEAF EPIDERMAL CHARACTERS OF ORNAMENTAL PLANTS, TOXIC FOR DOMESTIC ANIMALS. Patricia Nasca de Zamora DOI: https://doi.org/10.33017/RevECIPeru2009.0003/ RESUMEN El tejido epidérmico de los vegetales presenta un diseño característico para cada especie, de manera que muchas plantas pueden reconocerse a través de su estudio microscópico. Además, este tejido resiste el pasaje por el tracto digestivo de los animales, permaneciendo prácticamente inalterable. Basados en este hecho, los investigadores Baungartder y Martin (1939) idearon la técnica microhistológica, que consiste en estudiar la composición botánica de la dieta de animales herbívoros a través del análisis microscópico de fragmentos de epidermis vegetales encontrados en la materia fecal de los mismos. A lo largo de los años, el uso de esta técnica se extendió ampliamente, adaptándose a diferentes objetivos, tanto ecológicos como económicos. El objetivo del presente trabajo, que se llevó a cabo en la provincia de Tucumán, República Argentina, es describir las epidermis foliares de cuatro especies ornamentales tóxicas, a fin de aportar datos para la confección de una clave dicotómica de identificación de las mismas, para ser usada como elemento de diagnóstico en medicina veterinaria. Se extrajeron en laboratorio - con diversas técnicas - epidermis foliares de Evonymus japonicus, Hedera helix, Ficus benjamina y Vinca difformis; especies ornamentales citadas como tóxicas en la bibliografía veterinaria y cultivadas habitualmente en jardines particulares y espacios públicos de la Provincia. Se confeccionaron preparados microscópicos permanentes, se tomaron registros fotográficos y se describieron las características epidérmicas de cada especie, teniendo en cuenta la forma de las células, la presencia o ausencia de estomas, presencia de tricomas, tipos de estomas, tipos de tricomas, etc. Hedera helix y Vinca difformis presentan células epidérmicas de contorno lobulado, mientras que las células epidérmicas de Evonymus japonicus. y Ficus benjamina son isodiamétricas y poligonales. Las cuatro especies descriptas presentan estomas sólo en la zona internerval de la cara abaxial de sus hojas. Se encontraron tricomas simples solamente en la zona nerval de la epidermis adaxial de Vinca difformis, las demás epidermis son completamente glabras. Los caracteres encontrados en las especies estudiadas y volcados en las descripciones, constituyen un aporte de utilidad para la confección de una clave dicotómica de indentificación de estas plantas tóxicas a través de sus epidermis. Palabras clave: epidermis foliar, plantas ornamentales, tóxicas, medicina veterinaria. ABSTRACT The epidermal tissue of the vegetables presents a typical design for every species so that many plants can be recognized across its microscopic study. In addition, it resists the passage for the digestive tract of the animals, remaining practically inalterable. Based on this fact, Baungartder and Martin (1939) designed the microhistological technique, which consists of studying botanical composition of diet of herbivorous animals across the microscopic analysis of plant´s epidermis fragments found in the fecal matter. Throughout the years, the use of this technique spread widely, adapting to different aims, both ecological and economic. The aim of the present work, realized in Tucumán's province, Argentina, is to characterize epidermis of ornamental, toxic plants for domestic animals, in order to be used as element of diagnosis in veterinary medicine. Epidermis of Evonymus japonicus, Hedera helix, Ficus benjamina and Vinca difformis were extracted in laboratory. All of them are ornamental species, mentioned like toxic in the bibliography veterinary and cultivated habitually in particular gardens and public spaces of the Province. They were made prepared microscopic permanent, photographic records took and there were described the epidermal characteristics of every species, bearing in mind the form of the cells, the presence or absence of stomata and trichomes, and types of stomata and trichomes. Hedera helix and Vinca difformis present lobulated epidermal cells, whereas Evonymus japonicus and Ficus benjamina ones are isodiametrics and polygonal. Four species present stomata only in the internerval zone of abaxial epidermis. They were trichomes only in the nerval zone of adaxial epidermis of Vinca difformis. The epidermal characters found in the studied species, constitute an usefull contribution for the confection of a dichotomous indentification key of these toxic plants. Keywords: epidermis, ornamental toxic plants, veterinary medicine.
