Anti-Inflammatory Chilean Endemic Plants.

Medicinal plants have been used since prehistoric times and continue to treat several diseases as a fundamental part of the healing process. Inflammation is a condition characterized by redness, pain, and swelling. This process is a hard response by living tissue to any injury. Furthermore, inflammation is produced by various diseases such as rheumatic and immune-mediated conditions, cancer, cardiovascular diseases, obesity, and diabetes. Hence, anti-inflammatory-based treatments could emerge as a novel and exciting approach to treating these diseases. Medicinal plants and their secondary metabolites are known for their anti-inflammatory properties, and this review introduces various native Chilean plants whose anti-inflammatory effects have been evaluated in experimental studies. Fragaria chiloensis, Ugni molinae, Buddleja globosa, Aristotelia chilensis, Berberis microphylla, and Quillaja saponaria are some native species analyzed in this review. Since inflammation treatment is not a one-dimensional solution, this review seeks a multidimensional therapeutic approach to inflammation with plant extracts based on scientific and ancestral knowledge.

Phytochemical profile and antioxidant activity of extracts of the peruvian peppertree Schinus areira L. from Chile.

The Andean tree Schinus areira L. has multiple traditional uses, from the treatment of bronchitis and rheumatic diseases to menstrual cycle regulation and wound healing. With reported hypotensive, analgesic, antitumoral and anti-inflammatory properties, it acts predominantly against diseases related to oxidative stress. This study focuses on the antioxidant activity and phytochemical profile of the extracts of Schinus areira L. Serial extraction of the fruits was performed both by maceration and by Soxhlet. Total phenols and flavonoids were measured using the Folin-Ciocalteu method and AlCl3, respectively. In vitro antioxidant activity was determined by FRAP and DPPH. Results were similar for both extraction methods. Primary metabolites detected included carbohydrates, proteins and amino acids; secondary metabolites included tannins, flavonoids, saponins, steroids and triterpenes. Antioxidant activity was confirmed for ethyl acetate, methanolic and aqueous extracts. The methanolic extract had both the highest polyphenol content (>195 mg GAE/ g dry weight) and the highest antioxidant activity [EC50 > 476 µg/mL; >273 mg AA/g dry weight (DPPH); >301 mg AA/ g dry weight (FRAP)]. The extract does not produce macrophage cytotoxicity in RAW 264.7, which is indicated by an average cytotoxicity of 2% over 24 h. Our study serves as a starting point for future research on the pharmacological properties of Schinus areira L.

Dysentery by CTX-M Type ESBL Producing Shigella flexneri / Disentería por Shigella flexneri productora de BLEE tipo CTX-M

According to the World Health Organization, diarrheal infections cause 525 000 deaths of children under five years of age every year, and shigellosis. Shigellosis is a relevant cause of dysentery, which increases the morbidity and mortality in pediatric patients. Therefore, emergingthe emergence of antimicrobial resistant strains of Shigella is a concerningworrisome problem worldwide. We report the case of a 7-year-old patient with acute dysentery caused by CTX-M Type ESBL Producing Shigella flexneri, being. This was the first case treated in the Specialties Hospital of Specialties of the Armed Forces N°1, in Quito, Ecuador. The antibiogram demonstrated sensibilityshowed sensitivity to ampicillin-sulbactam. As a result, after five days of microbiologically directed treatment, the patient improved his condition without relapse. Proper clinical diagnoses and accurate laboratory studies like stool culture and antibiogram are crucial to givingindicate an appropriate therapy in infections caused by Shigella and other enteric bacilli(AU)

Según la Organización Mundial de la Salud, las infecciones diarreicas provocan 525 000 muertes de niños menores de cinco años de edad cada año. La shigelosis es una causa importante de disentería que aumenta la morbilidad y mortalidad de los pacientes pediátricos. Es por eso que el surgimiento de cepas de Shigella resistentes a los antibióticos es un preocupante problema a nivel mundial. Presentamos el caso de un paciente de 7 años de edad con disentería aguda provocada por Shigella flexneri productora de BLEE tipo CTX-M. Se trata del primer caso tratado en el Hospital de Especialidades de las Fuerzas Armadas Nº 1, en Quito, Ecuador. El antibiograma mostró sensibilidad a la combinación ampicilina/sulbactam. Al cabo de cinco días de tratamiento microbiológico, el paciente mejoró su estado y no se produjeron recaídas. Un diagnóstico clínico correcto, así como estudios precisos de laboratorio como los cultivos de heces y los antibiogramas, son vitales para indicar una terapia apropiada en las infecciones causadas por Shigella y otros bacilos entéricos(AU)

Diagnosis and management of posterior reversible encephalopathy syndrome in systemic lupus erythematosus. Case report / Diagnóstico y manejo de síndrome de encefalopatía posterior reversible asociado a lupus eritematoso sistémico. Reporte de caso clínico

ABSTRACT Posterior reversible encephalopathy syndrome (PRES) is a clinical-radiological disorder that may include encephalopathy, seizures, headache, and visual disturbances. It is associated with conditions that induce endothelial damage, causing vasogenic cerebral edema that can be observed in magnetic resonance scans. It occurs in <1% of patients with systemic lupus erythematosus (SLE). It is usually resolved with timely treatment, but delays may lead to neurological sequelae or death. A case of PRES is presented in a patient with SLE with severe activity, a hypertensive emergency, and lupus glomerulonephritis debuting with epileptic status. The outcome was satisfactory with anticonvulsants, as well as treatment for her cerebral edema and hypertension, along with control of other causal factors.

RESUMEN El síndrome de encefalopatía posterior reversible (PRES) es un trastorno clínico-radiológico caracterizado por encefalopatía, convulsiones, cefalea y alteraciones visuales. Se asocia a entidades que ocasionan daño endotelial, causando edema cerebral vasogénico evidente en resonancia magnética. En pacientes con lupus eritematoso sistémico (LES) se presenta en < 1%. Con tratamiento oportuno usualmente resuelve; caso contrario puede producir secuelas neurológicas o muerte. Se reporta el caso de PRES en una paciente con LES con actividad severa, emergencia hipertensiva y glomerulonefritis lúpica que comienza con estatus epiléptico. Evolucionó satisfactoriamente con tratamiento anticonvulsivante, antiedema cerebral, antihipertensivo y control de los demás factores causales.

Enfermedad por depósito de cristales de pirofosfato de calcio como ejemplo de forma de manifestación de la enfermedad en el adulto mayor / Calcium pyrophosphate dihydrate crystal deposition disease as an example of illness presentation in the elderly

Illness presentation in the elderly may be entirely non-specific, with fatigue, loss of function or the presence of geriatric syndromes. We report a 90 years old male consulting in the emergency room for delirium that persisted throughout hospitalization without finding a cause. During the course of hospitalization mild fever appeared and a left knee swelling became apparent. A synovial fluid aspiration showed a leukocyte count of 360 per field with 60% polymorphonuclear cells. The culture was negative. With a presumptive diagnosis of pseudogout, cochicine and celecoxib were started with remission of the confusional state. The patient was discharged 13 days after admission in good conditions.
