Absceso tubo-ovárico por granulicatella adiacens. Descripción de un caso / Tubo-ovarian abscess due to granulicatella adiacens. A review of a case

La mayoría de los abscesos tubo-ováricos son debidos a complicaciones asociadas a la enfermedad inflamatoria pélvica. Sin embargo, una minoría son secundarios a otros procesos como neoplasias o patologías intrabdominales. Se presenta el caso de un absceso tubo-ovárico, en una mujer de 36 años, intervenida previamente de apendicectomía. En el cultivo del material de drenaje del absceso creció Granulicatella adiacens, un microrganismo no involucrado habitualmente en este tipo de infecciones. Tras la descripción del caso, se discute la etiología de los abscesos tubo-ováricos y las peculiaridades del microorganismo implicado. (AU)

Most tubo-ovarian abscesses are due to complications associated with pelvic inflammatory disease. However, a minority are second-ary to other processes such as neoplasms or intraabdominal pathologies. A case of tubo-ovarian abscess is presented, in a 36-year-old woman, previously operated on for appendectomy. Granulicatella adiacens, a microorganism not usually involved in this type of infection, grew in the culture of the drainage material of the abscess. After the description of the case, the etiology of the tubo-ovarian abscesses and the peculiarities of the microorganism involved are discussed. (AU)

An intelligent tutoring system for supporting active learning: A case study on predictive parsing learning.

The way in which people learn and institutions teach is changing due to the ever-increasing impact of technology. People access the Internet anywhere, anytime and request online training. This has brought about the creation of numerous online learning platforms which offer comprehensive and effective educational solutions which are 100% online. These platforms benefit from intelligent tutoring systems that help and guide students through the learning process, emulating the behavior of a human tutor. However, these systems give the student little freedom to experiment with the knowledge of the subject, that is, they do not allow him/her to propose and carry out tasks on his/her own initiative. They are very restricted systems in term of what the student can do, as the tasks are defined in advance. An intelligent tutoring system is proposed in this paper to encourage students to learn through experimentation, proposing tasks on their own initiative, which involves putting into use all the skills, abilities tools and knowledge needed to successfully solve them. This system has been designed developed and applied for learning predictive parsing techniques and has been used by Computer Science students during four academic courses to evaluate its suitability for improving the student's learning process.

Características, evolución clínica y factores asociados a la mortalidad en UCI de los pacientes críticos infectados por SARS-CoV-2 en España: estudio prospectivo, de cohorte y multicéntrico / Patient characteristics, clinical course and factors associated to ICU mortality in critically ill patients infected with SARS-CoV-2 in Spain: a prospective, cohort, multicentre study

ANTECEDENTES: No se ha reportado plenamente la evolución clínica de los pacientes críticos de COVID-19 durante su ingreso en la unidad de cuidados intensivos (UCI), incluyendo las complicaciones médicas e infecciosas y terapias de soporte, así como su asociación con la mortalidad en ICU. OBJETIVO: El objetivo de este estudio es describir las características clínicas y la evolución de los pacientes ingresados en UCI por COVID-19, y determinar los factores de riesgo de la mortalidad en UCI de dichos pacientes. MÉTODOS: Estudio prospectivo, multi-céntrico y de cohorte, que incluyó a los pacientes críticos de COVID-19 ingresados en 30 UCIs de España y Andorra. Se incluyó a los pacientes consecutivos de 12 de Marzo a 26 de Mayo de 2020 si habían fallecido o habían recibido el alta de la UCI durante el periodo de estudio. Se reportaron los datos demográficos, síntomas, signos vitales, marcadores de laboratorio, terapias de soporte, terapias farmacológicas, y complicaciones médicas e infecciosas, realizándose una comparación entre los pacientes fallecidos y los pacientes dados de alta. RESULTADOS: Se incluyó a un total de 663 pacientes. La mortalidad general en UCI fue del 31% (203 pacientes). Al ingreso en UCI los no supervivientes eran más hipoxémicos [SpO2 sin mascarilla de no reinhalación, de 90 (RIC 83-93) vs 91 (RIC 87-94); p < 0,001] y con mayor puntuación en la escala SOFA - Evaluación de daño orgánico secuencial - [SOFA, 7 (RIC 5-9) vs 4 (RIC 3-7); p < 0,001]. Las complicaciones fueron más frecuentes en los no supervivientes: síndrome de distrés respiratorio agudo (SDRA) (95% vs 89%; p = 0,009), insuficiencia renal aguda (IRA) (58% vs 24%; p < 10−16), shock (42% vs 14%; p < 10−13), y arritmias (24% vs 11%; p < 10−4). Las súper-infecciones respiratorias, infecciones del torrente sanguíneo y los shock sépticos fueron más frecuentes en los no supervivientes (33% vs 25%; p = 0,03, 33% vs 23%; p = 0,01 y 15% vs 3%, p = 10−7), respectivamente. El modelo de regresión multivariable reflejó que la edad estaba asociada a la mortalidad, y que cada año incrementaba el riesgo de muerte en un 1% (95%IC: 1-10, p = 0,014). Cada incremento de 5 puntos en la escala APACHE II predijo de manera independiente la mortalidad [OR: 1,508 (1,081, 2,104), p = 0,015]. Los pacientes con IRA [OR: 2,468 (1,628, 3,741), p < 10−4)], paro cardiaco [OR: 11,099 (3,389, 36,353), p = 0,0001], y shock séptico [OR: 3,224 (1,486, 6,994), p = 0,002] tuvieron un riesgo de muerte incrementado. CONCLUSIONES: Los pacientes mayores de COVID-19 con puntuaciones APACHE II más altas al ingreso, que desarrollaron IRA en grados II o III y/o shock séptico durante la estancia en UCI tuvieron un riesgo de muerte incrementado. La mortalidad en UCI fue del 31%

BACKGROUND: The clinical course of COVID-19 critically ill patients, during their admission in the intensive care unit (UCI), including medical and infectious complications and support therapies, as well as their association with in-ICU mortality has not been fully reported. OBJECTIVE: This study aimed to describe clinical characteristics and clinical course of ICU COVID-19 patients, and to determine risk factors for ICU mortality of COVID-19 patients. METHODS: Prospective, multicentre, cohort study that enrolled critically ill COVID-19 patients admitted into 30 ICUs from Spain and Andorra. Consecutive patients from March 12th to May 26th, 2020 were enrolled if they had died or were discharged from ICU during the study period. Demographics, symptoms, vital signs, laboratory markers, supportive therapies, pharmacological treatments, medical and infectious complications were reported and compared between deceased and discharged patients. RESULTS: A total of 663 patients were included. Overall ICU mortality was 31% (203 patients). At ICU admission non-survivors were more hypoxemic [SpO2 with non-rebreather mask, 90 (IQR 83-93) vs 91 (IQR 87-94); p < 0.001] and with higher sequential organ failure assessment score [SOFA, 7 (IQR 5-9) vs 4 (IQR 3-7); p < 0.001]. Complications were more frequent in non-survivors: acute respiratory distress syndrome (ARDS) (95% vs 89%; p = 0.009), acute kidney injury (AKI) (58% vs 24%; p < 10−16), shock (42% vs 14%; p < 10−13), and arrhythmias (24% vs 11%; p < 10−4). Respiratory super-infection, bloodstream infection and septic shock were higher in non-survivors (33% vs 25%; p = 0.03, 33% vs 23%; p = 0.01 and 15% vs 3%, p = 10−7), respectively. The multivariable regression model showed that age was associated with mortality, with every year increasing risk-of-death by 1% (95%CI: 1-10, p = 0.014). Each 5-point increase in APACHE II independently predicted mortality [OR: 1.508 (1.081, 2.104), p = 0.015]. Patients with AKI [OR: 2.468 (1.628, 3.741), p < 10−4)], cardiac arrest [OR: 11.099 (3.389, 36.353), p = 0.0001], and septic shock [OR: 3.224 (1.486, 6.994), p = 0.002] had an increased risk-of-death. CONCLUSIONS: Older COVID-19 patients with higher APACHE II scores on admission, those who developed AKI grades II or III and/or septic shock during ICU stay had an increased risk-of-death. ICU mortality was 31%

Tumor de células de la granulosa del ovario de tipo adulto: revisión de 7 casos / Adult granulosa cell tumour of the ovary: A report of 7 cases

El tumor de células de la granulosa (TCG) es una neoplasia poco común que se clasifica en 2 subtipos, adulto y juvenil. Se presenta una serie de 7 casos de TCG, de tipo adulto, diagnosticados en nuestro hospital entre los años 2003 y 2017. La edad media al diagnóstico fue de 47 años, todos en estadio i. Se realizó biopsia intraoperatoria en 4 pacientes, con resultado de TCG en 3 de ellas y de cáncer de ovario en una. El estudio anatomopatológico se realizó en diferido en los otros 3 casos. El tratamiento fue siempre quirúrgico, realizándose adyuvancia con quimioterapia en un caso. Cinco pacientes presentaron hiperplasia endometrial concomitante, y una un carcinoma de mama de forma sincrónica. Durante el seguimiento se objetivaron 2 recurrencias. En nuestra serie se confirma la asociación del TCG a otras enfermedades hormonodependientes. A pesar del buen pronóstico de esta neoplasia los casos de recidiva tardía no son infrecuentes, y es necesario llevar a cabo un seguimiento a largo plazo

Granulosa cell tumour (TCG) is an uncommon neoplasia that has two subtypes, adult and juvenile. We present a report of 7 cases of adult-type TCG, that were diagnosed in our center during 2003 and 2017. The average age at diagnosis was 47 years, and all were in stage I. In four patients an intraoperative biopsy was performed, in three of which the diagnosis of TCG was obtained. Treatment was surgical in all cases, and in one case required adjuvant chemotherapy. Five patients presented with concomitant endometrial hyperplasia, and one had a synchronous breast carcinoma. During follow-up, 2 recurrences were observed. In our series, the association of TCG with other hormone-dependent pathologies was confirmed. Despite a good prognosis of this cancer, cases of late recurrence are not uncommon, and a long-term follow-up is required

Tratamiento quirúrgico de la enfermedad de Paget de la mama mediante técnica Grisotti. Descripción de un caso / Surgical management of Paget's disease of the breast using the Grisotti procedure. A case study

La afectación del complejo aréola-pezón (CAP) en la enfermedad de Paget está asociada en muchos casos a un carcinoma de mama subyacente. La rareza de la enfermedad hace que no se hayan establecido niveles de evidencia ni grados de recomendación concluyentes sobre el tipo de tratamiento quirúrgico de esta enfermedad. En la actualidad el tratamiento oncoplástico más radioterapia, en casos seleccionados, supone una alternativa a la indicación de mastectomía. Se presenta el caso de una paciente con enfermedad de Paget, y carcinoma intraductal subyacente, tratada con cirugía oncoplástica patrón de Grisotti seguida de radioterapia

The involvement of the nipple-areolar complex in Paget's disease is associated in many cases with an underlying breast cancer. The rarity of the disease means that no levels of evidence or conclusive grades of recommendation have been established concerning the type of surgical treatment of this disease. Nowadays, oncoplastic surgery plus radiotherapy, in selected cases, is an alternative to the indication of mastectomy. We present the case of a patient with Paget's disease, and underlying intraductal cancer treated with Grisotti's oncoplastic surgery procedure followed by radiotherapy

[Satellite center of human milk: Analysis of cost reduction]. / Centro satélite de donación y recepción de leche materna como alternativa a la creación de un banco de leche independiente. Análisis de reducción de costes.

INTRODUCTION: Donor milk is the second best alternative for a newborn after the mother's own milk, especially when the baby is a premature or a sick child since this milk has the advantage of protecting against necrotizing enterocolitis. There are currently 13 milk banks in Spain, however this is not sufficient to supply all Spanish neonatal units with donor milk. In order to bring donor milk to the babies in Neonatal Unit of the Regional University Hospital of Malaga, a Satellite Centre (CS) was created in 2012, depending on the Milk Bank of Virgen de las Nieves Hospital in Granada. AIM: Assessing the efficiency of a SC compared to an independent milk bank. METHOD: A study of cost minimization is used for the analysis. The cost of the implementation of the SC is calculated and compared to the cost of the implementation of the Milk Bank of Virgen de las Nieves of Granada. Additionally, the maintenance cost per year of the 2 models is compared, taking into account the running phase from June, 2012 through August 2015 in the SC. RESULTS: A SC implies savings of 88,852 Euro in equipment, and 24,572 Euro per year in maintenance compared to an independent milk bank. CONCLUSIONS: The efficiency of the SC is due to a better use of resources. A distribution network model of donor human milk, consisting of milk banks and SC, makes it possible to equally supply human milk to premature infants with a reduced cost.

Acculturation dimensions and 12-month mood and anxiety disorders across US Latino subgroups in the National Epidemiologic Survey of Alcohol and Related Conditions.

BACKGROUND: Individual-level measures of acculturation (e.g. age of immigration) have a complex relationship with psychiatric disorders. Fine-grained analyses that tap various acculturation dimensions and population subgroups are needed to generate hypotheses regarding the mechanisms of action for the association between acculturation and mental health. METHOD: Study participants were US Latinos (N = 6359) from Wave 2 of the 2004-2005 National Epidemiologic Survey of Alcohol and Related Conditions (N = 34 653). We used linear χ2 tests and logistic regression models to analyze the association between five acculturation dimensions and presence of 12-month DSM-IV mood/anxiety disorders across Latino subgroups (Mexican, Puerto Rican, Cuban, 'Other Latinos'). RESULTS: Acculturation dimensions associated linearly with past-year presence of mood/anxiety disorders among Mexicans were: (1) younger age of immigration (linear χ2 1 = 11.04, p < 0.001), (2) longer time in the United States (linear χ2 1 = 10.52, p < 0.01), (3) greater English-language orientation (linear χ2 1 = 14.57, p < 0.001), (4) lower Latino composition of social network (linear χ2 1 = 15.03, p < 0.001), and (5) lower Latino ethnic identification (linear χ2 1 = 7.29, p < 0.01). However, the associations were less consistent among Cubans and Other Latinos, and no associations with acculturation were found among Puerto Ricans. CONCLUSIONS: The relationship between different acculturation dimensions and 12-month mood/anxiety disorder varies across ethnic subgroups characterized by cultural and historical differences. The association between acculturation measures and disorder may depend on the extent to which they index protective or pathogenic adaptation pathways (e.g. loss of family support) across population subgroups preceding and/or following immigration. Future research should incorporate direct measures of maladaptive pathways and their relationship to various acculturation dimensions.

First-rank symptoms and premorbid adjustment in young individuals at increased risk of developing psychosis.

BACKGROUND: Individuals at clinical high risk (CHR) for psychosis represent a heterogeneous group with a high rate of comorbid psychiatric disorders. There is little information on whether certain qualitative aspects of psychotic symptoms among CHR individuals may be predictive of future psychosis. This study focused on describing the prevalence of first-rank symptoms (FRS) among a sample of CHR individuals and its association with future transition to psychosis and, from a neurodevelopmental perspective, the level of adjustment of individuals at CHR during their childhood was also analysed. SAMPLING AND METHODS: Participants comprised 60 individuals at CHR (according to the Comprehensive Assessment of At-Risk Mental States, CAARMS) at the time of their referral to an early intervention service and 60 healthy volunteers (HVs). All subjects were assessed by senior research clinicians using the Mini International Neuropsychiatric Interview (MINI), and the Positive and Negative Syndrome Scale (PANSS). FRS were defined according to Kurt Schneider's original classification, and information was collected from PANSS, CAARMS and clinical reports. Early premorbid functioning was measured using the Premorbid Adjustment Scale (PAS). We grouped individuals by number and type of FRS and analysed transitions to full-blown psychosis over a 2-year follow-up period. We also correlated the general social and functional adjustment of these individuals during their childhood (6-11 years of age) with the future development of mental states at CHR and FRS. RESULTS: Over 69% of CHR individuals had more than one DSM-IV psychiatric diagnosis, mainly within the affective and anxiety diagnostic spectra. At least one FRS was present in 43.3% of CHR individuals, and 21.6% of these had more than one. Auditory hallucinations and passivity experiences were the most commonly reported. Only 10% of individuals at CHR made a transition to first-episode psychosis (FEP) over 2 years and, except for passivity experiences, the presence of one or more FRS was not significantly associated with the transition to FEP. CHR individuals, especially those with FRS, had poorer premorbid functioning and adjustment as children across educational, social and peer relationship domains than HVs. However, this was not associated with FEP 2 years later. CONCLUSIONS: FRS might not be indicators of psychosis alone but of different psychiatric disorders. In line with the neurodevelopmental model of psychosis, individuals at CHR might be exhibiting several vulnerability traits and manifestations of abnormal developmental processes that might predict a future psychiatric disorder and/or long-term impairment.

Labor asistencial del equipo de guardia de neurología en un hospital terciario de Madrid: análisis prospectivo durante un año / Workload of on-call emergency room neurologists in a Spanish tertiary care centre. A one-year prospective study

Introducción: El envejecimiento poblacional, el aumento en la demanda asistencial y la instauración de tratamientos avanzados para el ictus agudo han originado que las urgencias neurológicas crezcan en número y complejidad. A pesar de esto, muchos centros hospitalarios de España carecen de guardias específicas de Neurología. Métodos: Estudio prospectivo durante un año (agosto 2010-julio 2011), que describe la labor asistencial del equipo de guardia de Neurología del Hospital terciario Gregorio Marañón de Madrid. Se recogieron las características sociodemográficas, las principales afecciones, las pruebas diagnósticas y el flujo de los pacientes atendidos, utilizando un registro diario mediante una base de datos informatizada. Los resultados fueron comparados con la asistencia médica general en urgencias. Resultados: Se atendió a 3.234 pacientes (3,48% del total de urgencias médicas), con una media de 11,15 pacientes/día. La edad media fue de 59 años. Las enfermedades más frecuentes fueron la cerebrovascular (34%), epilepsia (16%) y cefalea (8%). La estancia media en urgencias fue de 7,17 h. La tasa de ingreso hospitalario fue del 40% (7,38% del total de ingresos urgentes por afección médica). Los principales destinos de los pacientes hospitalizados fueron Unidad de Ictus (39,5%) y la planta de Neurología (33%). Se realizaron 76 procedimientos trombolíticos o intravasculares en ictus agudos. El 70% de los pacientes fue valorado fuera del horario laboral. Conclusiones: La atención neurológica es frecuente, variada y compleja, representando un alto porcentaje sobre el total de paciente atendidos o ingresados en urgencias. Nuestros resultados justifican la presencia física de un neurólogo de guardia 24 h en urgencias

Introduction: Population ageing, the rising demand for healthcare, and the establishment of acute stroke treatment programs have given rise to increases in the number and complexity of neurological emergency cases. Nevertheless, many centres in Spain still lack on-call emergency neurologists. Methods: We conducted a retrospective study to describe the role of on-call neurologists at Hospital General Universitario Gregorio Marañon, a tertiary care centre in Madrid, Spain. Sociodemographic characteristics, most common pathologies, diagnostic tests, and destination of the patients attended were recorded daily using a computer database. Results were compared with the general care data from the emergency department. Results: The team attended 3234 patients (3.48% of the emergency department total). The mean number of patients seen per day was 11.15. The most frequent pathologies were stroke (34%), epilepsy (16%) and headache (8%). The mean stay in the emergency department was 7.17 hours. Hospital admission rate was 40% (7.38% of emergency hospital admissions). The main destinations for admitted patients were the stroke unit (39.5%) and the neurology department (33%). Endovascular or thrombolytic therapies were performed on 76 occasions. Doctors attended 70% of the patients during on-call hours. Conclusions: Emergency neurological care is varied, complex, and frequently necessary. Neurological cases account for a sizeable percentage of both patient visits to the emergency room and the total number of emergency admissions. The current data confirm that on-call neurologists available on a 24-hour basis are needed in emergency departments

El empleo de un formulario estructurado mejora la calidad de la historia clínica de urgencias de pacientes con ictus agudos / The use of a pro-forma improves the quality of the emergency medical charts of patients with acute stroke

Introducción: La información obtenida mediante la historia clínica de urgencias (HCU) resulta determinante para el correcto manejo del paciente con ictus agudo. Pretendemos determinar si el empleo de un formulario estructurado (FE) para la elaboración de la HCU mejora la calidad de la información clínica.Material y métodos: Elaboramos un listado de 26 variables que consideramos importantes en el manejo del ictus agudo. Comparamos el número de variables recogidas en las HCU de pacientes ingresados en la unidad de ictus (UI) en enero-febrero 2009, antes de la implantación del FE (FE–), con los datos recogidos con el FE (FE+) (abril-mayo de 2009). Asimismo, analizamos la coincidencia con el diagnóstico definitivo al alta de la UI.Resultados: Analizamos 128 HCU, 80 FE–, 48 FE+. En las FE+, se recogió una media de 20,5 variables frente a 13,7 en las FE– (p<0,001); 16 variables se recogieron con frecuencia significativamente mayor (p<0,05) en las historias con FE+. Entre ellas destacaron: vida basal (100% vs 51%), escala Rankin previo al ictus (94% vs 1%), fecha y hora de inicio del ictus (100% vs 85%), fecha y hora de atención neurológica (100% vs 39%), NIHSS (92% vs 30%), resultado ECG (88% vs 59%), fecha y hora de realización de TC craneal (60% vs 1%). Coincidencia diagnóstica: diagnóstico nosológico/sindrómico: FE+: 94%, FE–: 60% (p<0,001), diagnóstico topográfico: FE+: 71%, FE–: 53% (p=0,03), diagnóstico etiológico: FE+: 25%, FE–: 9% (p=0,01).Conclusiones: El empleo de un FE permite mejorar cuantitativa y cualitativamente la información recogida en la HCU y aporta una mayor precisión diagnóstica

Introduction: The information obtained from the Emergency Medical Chart (EMC) is a key factor for the correct management of acute stroke. Our aim is to determine if the use of a pro-forma (PF) for filling in the EMC improves the quality of the clinical information. Material and methods:A PF was created from a list of 26 key-items considered important to be recorded in an EMC. We compared the number of items recorded in the EMC of patients admitted to our Stroke Unit (SU) in January-February 2009 (before PF was introduced) with the data obtained with the PF (April-May, 2009). We also analysed the agreement with the final diagnosis on discharge from the SU. Results:A total of 128 EMC were analysed, and the PF was used in 48 cases. The mean number of recorded items was 20.5 for the PF group and 13.7 for the non-PF charts (P<.001). Sixteen of the 26 items were recorded significant more frequently (P<.05) in the PF Group. The most notable scores being: previous baseline situation (100% vs 51%), previous Modified Rankin scale score (94% vs 1%), time of symptom onset (100% vs 85%), time of neurological evaluation (100% vs 39%), NIHSS score (92% vs 30%), ECG results (88% vs 59%), time of perform brain scan (60% vs 1%). Diagnostic agreement: nosological/syndromic diagnosis: PF group: 94%, Non-PF group: 60% (P<.001), topographic diagnosis: PF: 71%, Non-PF: 53% (P=.03), aetiological diagnosis: PF: 25%, Non-PF: 9% (P=.01).Conclusions: The use of a PF improves the quantity and quality of the information, and offers a better diagnostic accuracy

Different vascular risk factor profiles in ischemic stroke subtypes: a study from the "Sagrat Cor Hospital of Barcelona Stroke Registry".

OBJECTIVES: To characterize the vascular risk factor profiles in different subtypes of ischemic stroke. MATERIAL AND METHODS: The study population consisted of 1473 consecutive ischemic stroke patients collected in a prospective stroke registry. The prevalence of vascular risk factors in each stroke subtype was analyzed independently and in comparison with other subtypes of stroke pooled together by means of univariate analysis and logistic regression models. RESULTS: Hypertension was present in 52% of patients followed by atrial fibrillation in 27% and diabetes in 20%. The pattern of risk factors associated with atherothrombotic stroke included chronic obstructive pulmonary disease (COPD) (odds ratio [OR] = 2.63), hypertension (OR = 2.55), diabetes (OR = 2.26), transient ischemic attack (OR = 1.61), and age (OR = 1.03). Previous cerebral hemorrhage (OR = 4.72), hypertension (OR = 4.29), obesity (OR = 2.45), and diabetes (OR = 1.73) were strong predictors of lacunar stroke. In the case of cardioembolic stroke, atrial fibrillation (OR = 22.24), valvular heart disease (OR = 10.97), and female gender (OR = 1.66) occurred more frequently among patients with this stroke subtype than among the other stroke subtypes combined. CONCLUSION: Different potentially modifiable vascular risk factor profiles were identified for each subtype of ischemic stroke, particularly COPD in the case of atherothrombotic stroke and previous cerebral hemorrhage and hypertension in the case of lacunar infarction.

Treatment of experimental endocarditis due to ampicillin-susceptible or ampicillin-resistant Salmonella enteritidis.

Using two strains of Salmonella enteritidis, one susceptible and one resistant to ampicillin, we studied the efficacies of ampicillin, gentamicin, ampicillin plus gentamicin, ofloxacin, and cefotaxime for the treatment of experimental salmonella endocarditis. Rabbits were treated for 3 days with dosages of antibiotic selected to achieve concentrations in serum equivalent to those obtained in humans during therapy. Aortic salmonella endocarditis seemed to be very difficult to treat, and all antimicrobial regimens failed to achieve the complete sterilization of cardiac vegetations. In vitro studies did not accurately predict the in vivo response to therapy, and no correlations regarding the synergistic activity of the combination of ampicillin plus gentamicin were observed. For the ampicillin-susceptible S. enteritidis isolate, ampicillin and cefotaxime produced the greatest reduction in the number of organisms in vegetations, with no significant differences between them. For the ampicillin-resistant strain, the combination of ampicillin with gentamicin produced a synergistic effect that was not anticipated by the in vitro studies. Both cefotaxime and ofloxacin were effective in reducing the number of microorganisms in the vegetations, although the reduction produced by cefotaxime was less that that produced against the ampicillin-susceptible strain. Monotherapy with gentamicin exhibited only modest activity against the ampicillin-susceptible S. enteritidis strain.

[Therapeutic approaches to cryptosporidiosis. A review of the literature]. / Los abordajes terapéuticos de la criptosporidiosis. Revisión de la literatura.

Cryptosporidiosis is a coccidian infection that usually occurs in children an immunocompromised patients. With the AIDS (Acquired Immunodeficiency Syndrome) epidemic there have been an increased number of clinical cases and still we don't have an optimal therapeutic regimen to eradicate the infection. Since 1907 when the organism was first described, a large amount of anti-infective agents have been used without success. We present herein a review of the new therapeutic approaches, although none of them is satisfactory and new studies are required for the development of an optimal treatment. Symptomatic and nutritional support are the unique treatment we have so far.
