RESUMO

INTRODUCTION: The presence of stones in the urinary tract is a condition that has accompanied humans since ancient times. In colonial times, this condition was known as "stone pain" and its non-surgical management was based on the use of medicines derived from plants, animals and minerals. OBJECTIVE: To contextualize a medical prescription used to modulate stone pain in the 18th century in the New Kingdom of Granada. Additionally, to analyze its components and evaluate the basis of its possible phytotherapeutic effects on the disease and pain. MATERIAL AND METHOD: Document search in the Cipriano Rodríguez Santamaría Historical Archive of the Octavio Arizmendi Posada Library at Universidad de La Sabana. The document entitled "Prescription for bladder or kidney stone pain" was analyzed, and a complementary review of current scientific literature and original texts was performed with no time limits, in order to compare this prescription to related findings in the history of medicine. RESULTS: The transcription of the source document revealed several phytotherapeutic agents such as chamomile (Matricaria recutita), lilies (Lilium lancifolium), clover (Trifolium pratense), and mallow roots (Malva sylvestris), accompanied by a large amounts of water. CONCLUSIONS: There is scientific evidence that could explain the anti-inflammatory and antioxidant effects of all plant-derived medicines used in this prescription. Abundant water intake to increase urine volume was an essential part of treatment. However, the lack of more precise data related to the prescription and the evolution of the patients makes it difficult to analyze its therapeutic efficacy.

RESUMO

Introducción: Las recetas médicas o prescripciones históricas en el territorio de la Nueva Granada (hoy Colombia) revelan la evolución del manejo de la enfermedad en función de los efectos benéficos de administrar algún tipo de agente medicinal de origen vegetal, animal o mineral. Objetivo: Describir el tratamiento del reumatismo en los siglos XVIII y XIX, con base en dos recetas médicas de la época con base en la fundamentación contemporánea de su interacción fisiológica. Materiales y métodos: Búsqueda documental en el archivo Histórico de la Biblioteca Octavio Arizmendi Posada de la Universidad de La Sabana, donde se encontraron las recetas tituladas "Reumatismo" y "Rehumas". Resultados: Se describen cuatro clases de tratamientos para las enfermedades reumáticas utilizados en los siglos XVIII y XIX y orientados principalmente a la disminución del dolor. Este artículo presenta las bases fisiológicas de estos tratamientos, y cómo pudieron o no haber tenido algún efecto calmante al examinar su fisiología. Conclusiones: Estos medicamentos coloniales neogranadinos no ameritan su uso en el contexto actual de la medicina, pero pudieron representar una ayuda terapéutica en su momento.

Introduction: the medical prescriptions or historical prescriptions in the territory of New Granada (present-day Colombia) reveal the evolution of disease management given the beneficial effects of administering some type of medicinal agent of plant, animal or mineral origin. Objective: To describe the treatment of rheumatism in the 18th and 19th centuries based on two medical prescriptions of the time based on the contemporary rationale of their physiological interactions. Materials and methods: Documentary search in the Historical Archive of the Octavio Arizmendi Posada Library at Universidad de La Sabana in Colombia, where the prescriptions entitled "Reumatismo" and "Rehuma" were found. Results: Four classes of treatments for rheumatic diseases used in the 18th and 19th centuries and mainly oriented to pain reduction are described. This article presents the physiological basis of these treatments, and how they may or may not have had some calming effect when examining their physiology. Conclusions: These Neogranadian colonial drugs do not deserve their use in the current context of medicine, but they may have represented a therapeutic aid at the time.

RESUMO

Resumen: Introducción: Las infecciones por enterobacterias productoras de β-lactamasas de espectro extendido (BLEEs) ocasionan una gran carga a los sistemas de salud. Poco se conoce de las infecciones osteoarticulares, por lo que este trabajo estudió la prevalencia de estas infecciones en un hospital de tercer nivel. Material y métodos: Estudio de prevalencia en pacientes de un servicio de traumatología durante 2016, con criterios de infección proporcionados por el CDC de Atlanta, Georgia. Se utilizó el sistema VITEK® 2 AST-N272 (bioMérieux) para la identificación bacteriana a nivel de especie y para las pruebas de susceptibilidad antimicrobiana. Resultados: Se reportaron 7.85% (n = 86) con infecciones osteoarticulares; 22.09% (n = 19) fueron por enterobacterias BLEEs. Con un promedio de 77.1 días de hospitalización (DE 37.7) (46-200 días); el aislamiento del microorganismo se produjo 15 días posteriores al ingreso; 16 (84.2%) pacientes presentaron osteomielitis, tres (15.8%) tuvieron infección protésica de rodilla o cadera. El promedio de días de tratamiento fue de 60 días (21-129 días); 18 pacientes (94.7%) fueron dados de alta con resolución de su cuadro infeccioso; un paciente falleció con infección sobreagregada por neumonía debida a K. pneumoniae resistente a carbapenémicos. Discusión: La prevalencia de infecciones osteoarticulares por enterobacterias BLEEs no se pudo calcular con precisión, pero consideramos que se encuentra dentro de lo esperado, las medidas de control de infecciones requieren tener estándares más elevados y falta desarrollar programas de uso racional de antimicrobianos para controlar la aparición de estas patologías.

Abstract: Introduction: Infections of enterobacteria producing extended-spectrum ß-lactamases place a heavy burden on health systems. Little is known in osteoarticular infections, so this work studied the prevalence of these infections in a third-level hospital. Material and methods: Prevalence study in patients of a Traumatology Service during 2016, with infection criteria provided by the CDC in Atlanta, Georgia. The VITEK® 2 AST-N272 (bioMérieux) system was used for bacterial identification at the species level and for antimicrobial susceptibility tests. Results: 7.85% (n = 86) were reported with osteoarticular infections; 22.09% (n = 19) were by enterobacteria BLEEs. An average of 77.1 days of hospitalization (SD 37.7) (46-200 days); isolation of the microorganism occurred 15 days after entry. Sixteen (84.2%) patients had osteomyelitis, three (15.8%) had a prosthetic knee or hip infection. The average number of treatment days was 60 days (21-129 days). Eighteen patients (94.7%) were discharged with resolution of their infectious picture; one patient died with infection over aggregated pneumonia due to carbapenem-resistant K. pneumoniae. Discussion: The prevalence of osteoarticular infections by enterobacteria BLEEs could not be accurately calculated, but we consider it to be within what is expected, infection control measures require higher standards and there is a lack of development programs to use antimicrobials rationally to control the emergence of these pathologies.

RESUMO

En este trabajo se describe la aplicación de algunas técnicas empleadas para la rehabilitación de la memoria en personas con daño cerebral, con el fin de facilitar el aprendizaje de nombres de personas cercanas y conocidas en una paciente de 55 años, universitaria, diestra y quien como secuela de una encefalitis herpética presentó lesión isquémica en territorio frontotemporal izquierdo y severas alteraciones cognoscitivas y funcionales. Aunque la aplicación combinada de técnicas favorece los procesos de aprendizaje, éstos suelen ser lentos y desgastantes en personas con amnesia severa. No obstante, los resultados apoyan la propuesta de la conservación de la memoria implícita en esta población y favorecen el planteamiento de perspectivas de intervención.

In this work, we describe the application of some techniques used for the memory rehabilitation in people with brain damage, in order to facilitate learning the names of close and known persons in a 55 year old patient, college graduate, right handed, with herpetic encephalitis who presented injury in left frontotemporal region and severe cognitive and functional alterations. As show in the results, of the six names selected for the intervention, it was possible to work with three of them and to obtain significant results in two. Although the mix of techniques favors the learning processes, this process is usually slow in people with severe amnesia. However, these results support the proposal of the implicit memory conservation and favor the intervention from this perspective.

RESUMO

Select groups of bacteria, including prothescate species, have an unusual capacity to sequester gold and bioconcentrate it to very high levels. Hyphomonas adhaerens MHS-3 (MHS-3) is one such species, as demonstrated by Energy Dispersive Spectroscopy. Transmission electron microscopy revealed that the binding site was specific on the polar polysaccharide capsule. A capsuleless mutant and periodate-treated wild type did not sequester gold. The gold may interact with the same sites in the capsule that naturally adhere MHS-3 to surfaces in the marine environment.

RESUMO

The synthetic androgen 7alpha-methyl-19-nortestosterone (MENT) is a potent suppressor of gonadotrophin that has several advantages for long term administration to normal or hypoandrogenic men. The aim of this study was to examine MENT serum concentrations following subdermal insertion of MENT acetate (MENT Ac) implants and their effects on gonadotrophins, testosterone, dihydrotestosterone (DHT), sex hormone-binding globulin, prostate specific antigen and insulin-like growth factor-1 serum concentrations in normal men. A total of 45 healthy men were recruited at three clinics. Each subject received one, two or four implants for 28 days. Serum samples were obtained before insertion and on days 8, 15, 22, 29, 36 and 43 after implant insertion. The average daily dose delivered in vivo by one implant was approximately 500 microg. One, two or four MENT Ac implants produced dose dependent and sustained serum MENT concentrations for the entire duration of treatment of 0.7 +/- 0.1, 1.2 +/- 0.1 and 2.0 +/- 0.1 nmol/l respectively. This treatment induced a dose dependent decrease in gonadotrophin and androgen serum levels. Two and four implants induced maximal suppression that was maintained throughout treatment and was completely reversed after removal of the implants. The mean decreases were 93 +/- 1% for testosterone, 80 +/- 3% for DHT, 97 +/- 1% for luteinizing hormone and 95 +/- 1% for follicle stimulating hormone. No serious adverse reactions were reported by the volunteers and no consistent changes in clinical chemistry and haematology were found. These results indicate that MENT Ac implants are an efficient way of MENT administration and confirm the potent gonadotrophin and androgen suppressive effect of this drug.

RESUMO

Cs-137 and K-40 have been determined in soil samples and in wild edible mushrooms from a forest ecosystem located at the Nuclear Centre of Mexico (NCM) and in several surrounding localities. The transfer factors for Cs-137 were studied in 21 mushroom species from 1993 to 1997. The Cs-137 and K-40 determinations were performed using a gamma spectrometer system of low level counting with a high purity germanium (HPGe) detector. The local mushroom species that were found to show higher Cs-137 transfer factors were Clavariadelphus truncatus, Cortinarius caerulescens, Gomphus floccosus and Lyophyllum decastes. The Cs-137 levels obtained at the NCM in some mushroom samples were slightly lower than those from surrounding localities indicating that the nuclear facility has not emitted Cs-137 to the atmosphere.
