RESUMO

Objetivo: Determinar características clínico-epidemiológicas de neonatos con sepsis neonatal temprana en hospital público, Lima-Perú, 2016-2017. Materiales y métodos: Estudio observacional, retrospectivo. Se consideró todos los neonatos nacidos vivos en el Hospital Nacional Dos de Mayo diagnosticados con sepsis neonatal temprana el 2016-2017, excepto historias clínicas incompletas, totalizando 303. Se estudiaron variables maternas (edad, educación, estado civil, control prenatal, RPM, tipo de parto, infección urinaria, corioamnionitis, anemia) y neonatales (sexo, edad gestacional, peso, Apgar 1/5 minutos, clínica, hemocultivo, agente aislado, tratamiento y sensibilidad antibiótica). El programa Excel se usó para el procesamiento de datos; SPSSv25 para el análisis descriptivo. Se calculó incidencia de sepsis neonatal temprana. Resultados: Incidencia de sepsis neonatal temprana en 67,08/1000 nacidos vivos en el 2016 y 12,785 en el 2017, la cual fue confirmada en 2,98 (2016) y 4,7 (2017). 45 % de madres sin control prenatal adecuado o sin controles; la cuarta parte presentó anemia, infección urinaria, antecedente de aborto. Clínica de neonatos: taquipnea (52,80 %), taquicardia (17,50 %), hipotonía (18,20 %), fiebre (9,20 %); tratamiento ampicilina-amikacina en sepsis probable (86,54 %) y sepsis confirmada (85 %). Se aisló gérmenes en 8,40 % de casos, mayoría Gram positivos; Staphylococcus coagulasa-negativa, el más frecuente, resistente a clindamicina, oxacilina, ampicilina, cefotaxima, gentamicina y sensible a linezolid, vancomicina. Burkholderia gladioli, única bacteria Gram negativa encontrada, sensible a levofloxacino, ciprofloxacino, ceftriaxona, pero resistente a gentamicina y amikacina. Conclusiones: Clínica de sepsis neonatal temprana caracterizada por taquipnea, taquicardia, hipotonía y fiebre. Bacterias Gram positivas las más aisladas; predominó Staphylococcus coagulasa-negativa.

Objective: To determine the clinical-epidemiological characteristics of newborns with early-onset neonatal sepsis in a public hospital in Lima, Peru, 2016-2017. Materials and methods: An observational, retrospective study of 303 newborns born in Hospital Nacional Dos de Mayo, diagnosed with early-onset neonatal sepsis (2016-2017) and with complete medical records. Maternal variables: age, education, marital status, prenatal care, PROM, type of delivery, UTI, chorioamnionitis, anemia; neonatal variables: sex, gestational age, weight, Apgar, clinical signs, hemoculture, isolated organism, treatment, antibiotic sensitivity. Data processed in Excel and analyzed in SPSS Statistics V25. The incidence of early-onset neonatal sepsis was determined. Results: Incidence of early-onset neonatal sepsis: 67.08/1,000 (2016) and 127.85/1,000 (2017) live births. Incidence of confirmed early-onset neonatal sepsis: 2.98 (2016) and 4.7 (2017). Out of all mothers, 45 % received no adequate prenatal checkup or no checkups; 25 % presented anemia, UTI, history of abortion. Newborns had tachypnea (52.80 %), tachycardia (17.50 %), hypotonia (18.20 %), fever (9.20 %). The therapy included ampicillin-amikacin for probable (86.54 %) and confirmed (85 %) sepsis. Germs, mostly gram positive, were isolated from 8.4 % of the newborns. Coagulase-negative Staphylococcus was the most common bacteria, resistant to clindamycin, oxacillin, ampicillin, cefotaxime, gentamicin, and sensitive to linezolid, vancomycin. Burkholderia gladioli was the only identified gramnegative organism, sensitive to levofloxacin, ciprofloxacin, ceftriaxone but resistant to gentamicin, amikacin. Conclusions: The clinical presentation of neonatal sepsis included tachypnea, tachycardia, hypotonia and fever. Grampositive bacteria were the most commonly isolated species, prevailing coagulase-negative Staphylococci.

RESUMO

Resumen: ANTECEDENTES: la enfermedad tromboembólica venosa es una complicación que puede manifestarse durante o después de la hospitalización. Existen pocos antecedentes en nuestro país que evalúan el comportamiento médico en este tema. OBJETIVO: conocer la prescripción relacionada con el tipo, duración y posibles causas de la omisión de tromboprofilaxis en pacientes hospitalizados. MATERIAL Y MÉTODO: estudio descriptivo, transversal y no probabilístico en el que de septiembre a noviembre de 2016 se evaluaron médicos de Medicina Interna, Cirugía General, Terapia Intensiva y Urgencias. Se recolectaron datos por cuestionario y presentación de resultados a través de estadística descriptiva. También se evaluó la duración de la prescripción y la dosis administrada. RESULTADOS: se encuestaron 556 médicos adscritos, 14 jefes de servicio y 234 residentes total: 804 de siete hospitales de la Ciudad de México pertenecientes al sistema de salud. El 30% refirió que su hospital cuenta con un programa de tromboprofilaxis; 97.7% la considera segura y 1.2%, riesgosa. El 96% respondió que prescribe tromboprofilaxis en sus pacientes; 592 74% utilizan alguna escala de previsión clínica de enfermedad tromboembólica venosa. El 71% recomienda heparina de bajo peso molecular para tromboprofilaxis y 0.74% administra anticoagulantes orales de nueva generación. CONCLUSIONES: la enfermedad tromboembólica venosa es potencialmente prevenible; sin embargo, la prescripción muestra oportunidades de mejoría en aspectos de farmacología.

Abstract: BACKGROUND: Venous thromboembolic disease VTE is a complication that may occur during or after hospitalization. There are few antecedents in our country that evaluate the medical behavior in this subject. OBJECTIVE: To know the prescription related to type, duration and possible causes for omission of thromboprophylaxis in hospitalized patients. MATERIAL AND METHOD: A descriptive, transversal and non-probabilistic study was done, in which from September to November 2016 physicians of Internal Medicine, General Surgery, Intensive Care and Urgency were evaluated through a data collection by questionnaire and presentation of results through descriptive statistics. We also evaluated duration of prescription and dose administered. RESULTS: A total of 556 seconded physicians, 14 service heads, and 234 residents 804 in total were surveyed in seven hospitals in Mexico City belonging to the health system. Thirty percent reported that their hospital has a thromboprophylaxis program; 97.7% consider it safe and 1.2% risky; 96% responded that they prescribe thromboprophylaxis in their patients; 592 73.6% used some clinical prediction scale for VTE; 71% recommended low molecular weight heparin for thrombo prophylaxis and 0.74% administered new generation oral anticoagulants. CONCLUSIONS: Venous thromboembolic disease is potentially preventable; however, prescription shows opportunities for improvement in aspects of pharmacology.

RESUMO

ABSTRACT: The objective of the study was to determine the association between caries prevalence and body mass index (BMI) in preschool children in Santiago, Chile. Children aged 2 and 3 years old (n = 342) attending 16 nursery schools in Santiago, Chile were examined to record the status of dental caries using the modified criteria of the International Caries Detection and Assessment System (ICDAS II) (International Caries Detection and Assessment System (ICDAS) Coordinating Committee, 2005). BMI was calculated for each of the subjects and their nutritional state was classified as underweight, normal-weight, overweight and obesity according to the WHO. The caries prevalence (ICDAS 2-6 > 0) of the children was 45.9 % (IC 95 % 40.50 - 51.21). Data showed that none of the preschoolers were underweight. 39.1 % were classified as normal-weight (IC 95 % 33.98 - 44.38), 34.8 % as overweight (IC 95 % 29.72 - 39.86) and 26 % as obese (IC 95 % 21.34 - 30.96). Normal-weight children had a prevalence of 51.5 % of ICDAS 2-6 lesions and prevalence of 28.3 % of ICDAS 5-6 lesions. Children with overweight had prevalence of 51.4 % ICDAS 2-6 lesions and of 19.3 % ICDAS 5-6 lesions, and obese children of 39.5 % and 25.8 % respectively. Subjects with normal-weight presented a mean of ICDAS 2-6 caries lesions significantly higher (p < 0.05) than the rest of the children. In conclusion, normal-weight preschool children presented a higher prevalence of caries lesions than those with overweight and obesity. Iso-BMI was found to be associated with lower dental caries and severity. Future studies should address which specific factors related to overweight in children might be protective against dental caries.

RESUMEN: La caries dental es una enfermedad crónica multifactorial que afecta a niños denominada Caries Temprana de la Infancia (CTI). Su etiología es multifactorial y se asocia a determinantes biológicos, conductuales y sociodemográficos. Entre estos, se ha planteado la obesidad como presunto factor de riesgo para el desarrollo de caries en población infantil. El objetivo de este estudio fue establecer si existía o no asociación entre la presencia de lesiones de caries y el estado nutricional en una muestra de 342 preescolares entre 1 y 4 años de edad, que asisten a jardines infantiles de la Fundación INTEGRA, en la Región Metropolitana de Santiago. Se realizaron exámenes clínicos dentales y medición de la talla y peso. Se calculó IMC para cada uno de los sujetos y su estado nutricional fue clasificado como por debajo del peso adecuado, peso normal o normopeso, sobrepeso y obesidad según los gráficos y tablas de la OMS. La prevalencia total de lesiones de caries (ICDAS II = 2 -6) fue de 45,9 % (IC 95 % 40,59 - 51,21). El estado nutricional de la muestra completa fue de 0 % bajo el peso normal, 134 (39,1 %) niños presentaron peso normal (IC 95 % 33,98 - 44,38), 119 niños (34,8 %) presentaron sobrepeso (IC 95 % 29,72 - 39,86) y a 89 (26 %) niños se les diagnosticó obesidad (IC 95 % 21,34 - 30,96). Los sujetos con normopeso presentaron un promedio de lesiones de caries (ICDAS II = 2 - 6) significativamente mayor (p < 0,05). Por lo tanto, se puede concluir que los preescolares con peso normal presentaron mayor número de lesiones de caries de acuerdo al criterio ICDAS II, que aquellos preescolares con sobrepeso y obesidad.

RESUMO

Se presentan tres casos de nacimiento alto de la arteria radial, todos en el miembro derecho, uno a nivel del tercio superior de la arteria braquial, el segundo caso a nivel del tercio medio de la misma y en el tercer caso el nacimiento de la arteria radial se produce a nivel de la arteria axilar. En todos los casos tienen un trayecto superficial en el brazo y antebrazo. En la mano forman el arco palmar arterial profundo de manera habitual. Estos casos representan el 7,5% de los 40 miembros disecados. El origen alto de la arteria radial es la variante más frecuente dentro de las anomalías del árbol arterial del miembro superior. Su importancia radica en el aumento de los procedimientos percutáneos sobre la arteria radial en cateterismos coronarios y en el cada vez más utilizado colgajo radial en las cirugías reconstructivas. Su trayecto superficial favorece los traumatismos y la confusión con venas, situación que puede ocasionar inyecciones medicamentosas accidentales en estas arterias con sus graves consecuencias.

We present three cases of high birth of the radial artery, all on the right limbone at the upper third of the brachial artery, the second at the middle third of the artery, and in the third case the radial artery arises at the level of the axillary artery. In all cases they have a superficial path in the arm and forearm. In the hand they form the deep arterial arch of the palmar in the usual way. These cases represent 7.5% of the 40 dissected members. The high birth of the radial artery is the most frequent variant within the arterial tree anomalies of the upper limb. Its importance lies in the increase of the percutaneous procedures on the radial artery in coronary catheterisms and in the increasingly used radial flap in the reconstructive surgeries. Its superficial pathway favors trauma and confusion with veins, a situation that can cause accidental drug injections in these arteries with their serious consequences.

RESUMO

The aim of this study was to compare milk supplemented with probiotic lactobacilli with standard milk for the increment of caries in preschool children after 10 mo of intervention. The study was a triple-blind, placebo-controlled randomized trial. Participants were children aged 2 and 3 y (n = 261) attending 16 nursery schools in a metropolitan region in Chile. Nursery schools were randomly assigned to 2 parallel groups: children in the intervention group were given 150 mL of milk supplemented with Lactobacillus rhamnosus SP1 (10(7) CFU/mL), while children in the control group were given standard milk. Interventions took place on weekdays for 10 mo. Data were collected through a clinical examination of participants. The primary outcome measure was the increment of caries in preschool children. This was assessed using the International Caries Detection and Assessment System (ICDAS). The dropout rate was 21%. No differences in caries prevalence were detected between the groups at baseline (P = 0.68). After 10 mo of probiotic intake, the caries prevalence was 54.4% in the probiotic group and 65.8% in the control group. The percentage of new individuals who developed cavitated lesions (ICDAS 5-6) in the control group (24.3%) was significantly higher than that in the probiotic group (9.7%). The increment of dental caries showed an odds ratio of 0.35 (P < 0.05) in favor of the probiotic group. At the cavitated lesion level, the increment of new caries lesions within the groups showed 1.13 new lesions per child in the probiotic group compared with 1.75 lesions in the control group (P < 0.05). The probiotic group showed an increment of 0.58 ± 1.17 new lesions compared with 1.08 ± 1.70 new lesions observed in the control group. The difference in caries increment was significant at the cavitated lesion level (P < 0.01). In conclusion, the regular long-term intake of probiotic-supplemented milk may reduce caries development in high-caries preschool children (ClinicalTrials.gov: NCT01648075).

RESUMO

Objective. To evaluate the pharmacological, clinical and toxicological effects of celecoxib and meloxicam for analgesia for 30 days in dogs with hip osteoarthritis. Materials and methods. Twenty-four patients were evaluated, 75% were females with an average age of 7.16 ± 2.06 years and twenty five percent were males with an average age of 7.83 ± 2.22 years. All patients had hip osteoarthritis and they were randomized into two groups; one group received oral celecoxib 5 mg/kg every 12 hours during one month and the second group received oral meloxicam 0.2 mg/kg every 24 hours during 1 month. The patients were evaluated for analgesia, and hematological, renal, liver, and coagulation tests on days 0, 10th and 30th after treatment initiation, and a gastric endoscopy on day 30. Statistical analysis was performed using a HSD Tukey test and c² with a 5% level of statistical significance. Results. Both drugs reduced articular pain according to the Melbourne scale during the 30 days of treatment (p≤0.05). Hematological, renal, hepatic and coagulation tests were normal in both treatment groups. All patients presented chronic gastritis on endoscopy on day 30th. Conclusions. Both drugs decreased pain at day 30th without causing alterations in hematological, renal, hepatic or coagulation tests after 30 days of treatment. However, both drugs induced chronic gastritis.

RESUMO

The aim of this study was to determine the omeprazol treatment effect on equine gastric fluid pH with food andwithout food administering for the duration of the experiment. To carry this project out, 7 animals were chosenbetween the ages of 3 and 10 (2 males and 5 females) from the Centro de Veterinaria y Zootecnia - CES. In thecontrolled treatment they received 200 ml of physiological saline and were treated using omeprazol pellets whichwere administered in a single dose of 4 mg/kg via a nasogastric insertion, and in two groups with or without foodduring the treatment. Gastric pHs were measured at 0 hour (fasting before treatment) and then at hours 3, 5, 7, 9,11 and 24 after treatment. In animals consuming food, both treatments showed post treatment gastric pH increases,which can be explained by the ad libitumn food management in both treatments, which may increasing post prandialpH. In fasting animals, we observed that in the controlled treatment the pH was maintained at very low levels atall measurement times, while in the omeprazol treatment the pH increased significantly. These results show thattreatment with omeprazol pellets at a dose of 4 mg/kg via nasogastric insertion increased gastric pH in healthyanimals that are not eating food and that this effect was similar to them being administered food.

El objetivo de este estudio fue determinar el efecto del tratamiento con omeprazol sobre el pH del fluido gástrico en equinos, con la administración del alimento y sin ella. Para llevar a cabo este proyecto se eligieron siete animalesentre los 3 y 10 años de edad (2 machos y 5 hembras) del Centro de Veterinaria y Zootecnia – CES. El tratamientocon omeprazol se administró en pellets a una dosis única de 4 mg/kg, por vía nasogástrica, para los grupos cono sin alimento. Para el tratamiento control, se administraron 200 ml de solución salina fisiológica. En todos lostratamientos se midieron los pHs gástricos a la hora 0 (ayunas antes del tratamiento) y luego a las horas 3, 5, 7, 9, 11 y 24, postratamiento. Los animales que consumieron alimento con y sin omeprazol presentaron aumentos de pHgástrico postratamiento, lo que se puede explicar por el sumistro de heno ad libitum en ambos tratamientos. En losanimales en ayuno se observó que en el tratamiento control, el pH se mantuvo en niveles muy bajos en todas las horasde medición, mientras que en el tratamiento con omeprazol, el pH aumentó notablemente. Los resultados muestran que el tratamiento con pellets de omeprazol a una dosis de 4 mg/kg vía nasogástrica aumentó el pH gástrico en animales sanos que no están consumiendo alimento y que este efecto fue similar que cuando se administró el mismo.

A resistência é o mecanismo pelo qual a bactéria pode diminuir a ação dos agentes antimicrobianos de formanatural ou adquirida; dentro das causas mais frequentes está a utilização indiscriminada destes agentes em pacienteshumanos e produções pecuárias. Desde 1990 tem identificado novas cepas resistentes de bactérias que originaramdoenças zoonóticas emergentes. Dentro destas a zoonose, a salmonelose é considerada a doença mais difundida anível mundial, a ampla distribuição na natureza entre animais silvestres, domésticos e o meio ambiente, produz umarápida propagação de seus mais de 2500 sorotipos no homem. Contudo, a grande preocupação pela infecção com esteinteiro patógeno é devido aos cada vez mais elevados fracassos nos tratamentos com antimicrobianos convencionais,ocasionados pela alta resistência bacteriana a estes fármacos. O presente artigo é uma revisão sobre a problemáticaque gerou a resistência de Salmonella no homem e os animais, contem também estratégias de prevenção e controledeste fenômeno, que está distante de terminar e permitem o fortalecimento da saúde pública.
