RESUMO

Portal hypertension may have major consequences on the pulmonary vasculature due to the complex pathophysiological interactions between the liver and lungs. Portopulmonary hypertension (PoPH), a subset of group 1 pulmonary hypertension (PH), is a serious pulmonary vascular disease secondary to portal hypertension, and is the fourth most common subtype of pulmonary arterial hypertension. It is most commonly observed in cirrhotic patients; however, patients with noncirrhotic portal hypertension can also develop it. On suspicion of PoPH, the initial evaluation is by a transthoracic echocardiogram in which, if elevated pulmonary pressures are shown, patients should undergo right heart catheterization to confirm the diagnosis. The prognosis is extremely poor in untreated patients; therefore, management includes pulmonary arterial hypertension therapies with the aim of improving pulmonary hemodynamics and moving patients to orthotopic liver transplantation (OLT). In this article, we review in detail the epidemiology, pathophysiology, process for diagnosis, and most current treatments including OLT and prognosis in patients with PoPH. In addition, we present a diagnostic algorithm that includes the current criteria to properly select patients with PoPH who are candidates for OLT.

RESUMO

Drug-induced aseptic meningitis is a rare entity. Diagnosis of drug-induced aseptic meningitis can be challenging due to the difficulty in distinguishing clinical presentation from bacterial or viral meningitis. We present a case of a 52-year-old Caucasian female patient who presented to the emergency room on two different occasions with severe headache, neck pain, and confusion. Initial cerebrospinal fluid (CSF) analysis showed lymphocytic pleocytosis, and empirical intravenous acyclovir was initiated. Bacterial and viral CSF analysis and cultures were negative. The patient completely recovered. Several days later, the patient returned to the emergency room with similar symptoms. Second CSF analysis revealed neutrophilic pleocytosis, and empirical intravenous antibiotic and antiviral therapy were started. Bacterial, fungal, and viral CSF analysis and cultures were negative. Imaging studies of the brain were unremarkable on both occasions. The patient reported taking trimethoprim-sulfamethoxazole (TMP-SMX) for right foot infection before and after the initial presentation. The patient's symptoms resolved without neurological sequelae after discontinuation of TMP-SMX. This case report highlights the importance of taking a detailed history to diagnose drug-induced aseptic meningitis.

RESUMO

Preterm birth is a serious global health problem and the leading cause of infant death before 5 years of age. At least 40% of cases are associated with infection. The most common way for pathogens to access the uterine cavity is by ascending from the vagina. Bioluminescent pathogens have revolutionized the understanding of infectious diseases. We hypothesized that bioluminescent Escherichia coli can be used to track and monitor ascending vaginal infections. Two bioluminescent strains were studied: E. coli K12 MG1655-lux, a nonpathogenic laboratory strain, and E. coli K1 A192PP-lux2, a pathogenic strain capable of causing neonatal meningitis and sepsis in neonatal rats. On embryonic day 16, mice received intravaginal E. coli K12, E. coli K1, or phosphate-buffered saline followed by whole-body bioluminescent imaging. In both cases, intravaginal delivery of E. coli K12 or E. coli K1 led to bacterial ascension into the uterine cavity, but only E. coli K1 induced preterm parturition. Intravaginal administration of E. coli K1 significantly reduced the proportion of pups born alive compared with E. coli K12 and phosphate-buffered saline controls. However, in both groups of viable pups born after bacterial inoculation, there was evidence of comparable brain inflammation by postnatal day 6. This study ascribes specific mechanisms by which exposure to intrauterine bacteria leads to premature delivery and neurologic inflammation in neonates.

RESUMO

ANTECEDENTES: Es habitual el ingreso hospitalario de los lactantes < 3 meses con infección del tracto urinario. Estudios recientes plantean un manejo menos intensivo para los que tienen más o igual a 29 días. OBJETIVOS: Analizar la frecuencia de complicaciones en los lactantes < 3 meses con infección del tracto urinario y conocer los microorganismos responsables y su sensibilidad antibiótica. MÉTODOS: Estudio retrospectivo. Se incluyen los lactantes < 3 meses con sedimento urinario patológico y urocultivo positivo de una muestra de orina recogida por sondaje vesical atendidos en Urgencias de 2007 a 2012. Se describen variables clínico-epidemiológicas y microbiológicas (microorganismos aislados y su sensibilidad antibiótica). Se analiza la frecuencia de complicaciones (bacteriemia, meningitis bacteriana, nefronía/absceso renal, intervención quirúrgica, ingreso en Unidad de Cuidados Intensivos y exitus) para toda la muestra y por subgrupos etarios (< 29, 29-60 y 61-90 días). RESULTADOS: Se incluyen 460 casos; 137 (29,8%) < 29 días, 166 (36,1%) 29-60 días y 157 (34,1%) 61-90 días. Veinticuatro (5,4%; IC 95%: 3,6-7,8) presentan bacteriemia; 15 (10,9%; IC 95%: 6,7-17,3) son < 29 días; 8 (4,9%; IC 95%: 2,5-9,4) de 29-60 días y uno (0,7%; IC 95%: 0,1-3,7) de 61-90 días (p < 0,001). Un (0,8%) neonato presenta meningitis bacteriana, y 2 (0,4%), abscesos renales. Escherichia coli es el principal microorganismo aislado en el urocultivo (87,2%), con una sensibilidad para amoxicilina-ácido clavulánico, gentamicina y cefixima del 89,2, 97,0 y 96,0%, respectivamente. CONCLUSIÓN: La frecuencia de complicaciones es baja en los < 3 meses con infección del tracto urinario, especialmente en los más o igual a 29 días; detectar los pacientes con bajo riesgo de complicaciones posibilitaría un manejo menos intensivo. La sensibilidad antibiótica de Escherichia coli se mantiene estable; su monitorización es esencial para optimizar el tratamiento antibiótico empírico


OBJECTIVE: The objective of this study was to assess the usefulness of a software tool integrated into the medical electronic history at the time of emergency triage. The aim was the early detection of patients with severe sepsis, and the potential impact of this software tool on reducing the mortality rate in patients treated. METHOD: The study consisted of two comparative samples. Patient selection was performed retrospectively into two groups using ICD-9 codes from the hospital and emergency department discharge reports. The codes were 038.9, 995.9 and 995.92 for sepsis, and 785.52 for severe sepsis and septic shock. The sample called «alarms» consisted of patients studied after implementing the sepsis alarm system in the Emergency Department computer system. There were two types of alarms, a serious one and an alert one depending on the on vital signs defined. The historical sample called «no alarms» consisted of patients seen in the Emergency Department during the year before the introduction of the alarm system. RESULTS: The compliance rate of the sepsis treatment package was higher in the «alarms» sample, compared to the sample without alarms, with blood cultures, 96.3% versus 80.9% (P < .001), antibiotic treatment in less than one hour, 62.9% vs. 39.3% (P < .001), determination of lactic acid, 91.4% vs. 77.9% (P < .001), and applying appropriate volume, 57.7% vs 54.3% (P = .052), respectively. The hospital mortality was reduced in absolute terms from 25% in the sample without alarms to 13.6% in the sample with alarms. Survival at 30 days was higher in the sample with alarms (Log Rank = .004). CONCLUSIONS: There were no studies that evaluated the effectiveness of an alarm system in our literature search. An electronic identification system for patients with sepsis allows acting earlier, better compliance with basic measures, and a reduction in hospital stay and mortality

RESUMO

BACKGROUND: Infants less than 3 months of age with urinary tract infection are usually hospitalized. Recent studies show that a less aggressive management for those patients aged ≥ 29 days may be feasible. OBJECTIVES: To determine the complication rate in infants<3 months of age with urinary tract infection, and to identify the causative agents and their antibiotic susceptibility. METHODS: A retrospective study was conducted on infants<3 months of age with positive urinalysis results, together with a positive urine culture from a catheterized specimen and seen in the Emergency Department from 2007 to 2012. Demographics, clinical and microbiology (microorganism isolated and antibiotic susceptibility) data were collected. The complications rate (bacteremia, bacterial meningitis, renal abscess, surgical intervention, Intensive Care Unit admission, or death) were calculated for the overall sample and for different age groups (<29, 29-60, and 61-90 days). RESULTS: A total of 460 patients are included; 137 (29.8%)<29, 166 (36.1%) 29-60, and 157 (34.1%) 61-90 days of age. Twenty four (5.4%; 95% CI: 3.6-7.8) had bacteremia; 15 (10.9%; 95% CI: 6.7-17.3) were<29 days; 8 (4.9%; 95% CI: 2.5-9.4) were 29-60 days, and one (0.7%; 95% CI: 0.1-3.7) was 61-90 days of age (P<.001). One neonate (0.8%; 95% CI: 0.1-4.1) had bacterial meningitis, and 2, renal abscess. Escherichia coli was the common pathogen identified (87.2%) in the urine culture, with a susceptibility to amoxicillin-clavulanate, gentamicin, and cefixime of 89.2, 97.0, and 96.0%, respectively. CONCLUSION: Complications are low in infants<3 months of age with UTI, especially in those ≥ 29 days of age. The identification of patients at very low risk for complications would allow a less aggressive management. Escherichia coli antibiotic susceptibility remains stable, but continuing careful surveillance is essential to optimize empirical antibiotic treatment.

RESUMO

BACKGROUND: Exposure to the dipyridyl herbicide paraquat can cause many manifestations of toxicity, and is a common method of suicide in developing countries. CASE REPORT: We present a case of a 20 year old healthy gentleman who intentionally overdosed on paraquat in a suicide attempt. He presented to the hospital within 4 hours of ingestion. Despite standard supportive measures, the patient's clinical condition worsened. He developed ulceration of his oral mucosa. He also developed acute non-oliguric renal failure and acute liver injury. After his mental status began to deteriorate, the patient expired. CONCLUSIONS: There are several therapies that may have helped this patient's condition. An explanation about the pathophysiology of toxicity and updated information on treatment is provided for this common condition with poor prognosis.

RESUMO

Resistance of melon (Cucumis melo L.) to Melon necrotic spot virus (MNSV) is inherited as a single recessive gene, denoted nsv. No MNSV isolates described to date (e.g., MNSV-Malpha5), except for the MNSV-264 strain described here, are able to overcome the resistance conferred by nsv. Analysis of protoplasts of susceptible (Nsv/-) and resistant (nsv/nsv) melon cultivars inoculated with MNSV-264 or MNSV-Malpha5 indicated that the resistance trait conferred by this gene is expressed at the single-cell level. The nucleotide sequence of the MNSV-264 genome has a high nucleotide identity with the sequences of other MNSV isolates, with the exception of its genomic 3'-untranslated region (3'-UTR), where less than 50% of the nucleotides are shared between MNSV-264 and the other two MNSV isolates completely sequenced to date. Uncapped RNAs transcribed from a full-length MNSV-264 cDNA clone were infectious and caused symptoms indistinguishable from those caused by the parental viral RNA. This cDNA clone allowed generation of chimeric mutants between MNSV-264 and MNSV-Malpha5 through the exchange of the last 74 nucleotides of their coat protein (CP) open reading frames and the complete 3'-UTRs. Analysis of protoplasts of susceptible and resistant melon cultivars inoculated with chimeric mutants clearly showed that the MNSV avirulence determinant resides in the exchanged region. The carboxy-termini of the CP of both isolates are identical; therefore, the avirulence determinant likely consists of the RNA sequence itself. We also demonstrated that this genomic region contains the determinant for the unique ability of the isolate MNSV-264 to infect noncucurbit hosts (Nicotiana benthamiana and Gomphrena globosa).

RESUMO

Se estudiaron dos grupos de 50 pacientes recién nacidos. El primer grupo estuvo conformado por 50 casos (25 del HNGAY y 25 del HNHU), en los cuales se determinaron los niveles de anticuerpos antitoxoplasma IgG e IgM. Encontramos mejores resultados por método de quimioluminiscencia (QML) que por ELISA. Así tenemos que por QML fueron positivos para IgM, 6 por ciento (3/50) y para IgG 44 por ciento (22/50); mientras que por ELISA se encontró para IgM 4 por ciento (2/50), y para IgG 22 por ciento (14/50). El segundo grupo sirvió de control; IgG por ELISA fue positivo en 12 por ciento (6/50), y por QML fue positivo en 18 por ciento (9/50).

RESUMO

Objetivo: identificar el cuadro clínico-patológico y determinar la tasa de recurrencia y los factores pronósticos que influyen en la sobrevida a 5 años del carcinoma infiltrante de mama. Material: Revisión retrospectiva de las historias clínicas de 39 pacientes con carcinoma de mama invasor operable con axila negativa, sometidas a mastectomía radical clásica (n igual 29) o modificada (n igual 10) desde 1966 a 1995. Lugar: Hospital Belén, Trujillo. Resultados: La edad media fue 49 años y el tiempo medio de enfermedad 9,8 meses. Veinte pacientes fueron posmenopáusicas y diecinueve premenopáusicas. Las molestias más frecuentes fueron la presencia de tumor (100 por ciento) y dolor (25,6 por ciento). La mama izquierda (66,7 por ciento) y el cuadrante superoexterno (48,7 por ciento) fueron los mayormente comprometidos. El tipo histológico más frecuente fue el carcinoma ductal infiltrante (89,8 por ciento). Las tasas de recurrencia local y a distancia a 5 años posmastectomía fueron de 15,4 por ciento y 20,5 por ciento, respectivamente. En la serie total, la tasa de sobrevida a 5 años, según el método actuarial de Kaplan-Meier, fue de 76 por ciento. En el análisis univariado, usando la prueba de Log-Rank, fueron factores pronósticos significativamente relacionados con la sobrevida el grado histológico (p menor 0,019 y nuclear (p menor 0,01), la invasión de vasos sanguíneos (p menor 0,05), el índice mitótico (p menor 0,05); la fibrosis peritumoral (p menor 0,01), la multicentricidad del tumor (p menor 0,05) y el tipo de mastectomía (p menor 0.01); y en el análisis multivariante de Cox, sólo tuvieron significancia estadística el grado histológico (p igual 0,0026) y nuclear (p igual 0,0026), el índice mitótico (p igual 0,0191) y el tipo de mastectomía son factores que influyen significativamente en la sobrevida de pacientes con carcinoma de mama operable y axila negativa y estos parámetros deben ser tenidos en consideración en la estratificación de pacientes para un tratamiento adyuvante postoperatorio.

RESUMO

Se estudian retrospectivamente 60 pacientes con carcinoma de vesícula biliar (CVB) operados entre 1966 y 1993 en el Hospital Belén, Trujillo, Perú. La proporción de hombres a mujeres fue 1:7.5 y el promedio de edad fue de 61 años. La ultrasonografía (n=19), y la colecistografía oral (n=23) hicieron el diagnóstico específico en el 21 por ciento y 0 por ciento de los casos respectivamente. Los procedimientos quirúrgicos empleados fueron: colecistectomía simple (n=56), hepatectomía derecha (n=2), duodenopancreatectomía (n=1), y colecistectomía extendida (n=1); y nuestra tasa de resecabilidad es actualmente del 50 por ciento. La colecistectomía simple fue un procedimiento potencialmente curativo en pacientes con cáncer in situ (EC-0) y precoz (EC-1). En nuestra serie, la mortalidad operatoria global fue 11.6 por ciento y la sobrevida a 5 años fue 15 por ciento. Litiasis vesicular estuvo presente en el 95 por ciento de los pacientes, muchos tumores (58 por ciento) fueron difusos o estuvieron asociados con empiema vesicular (38 por ciento). El estadio clínico, la profundidad de invasión, el tipo y grado histológicos fueron factores pronósticos de sobrevida. Este trabajo evidencia la dificultad en el diagnóstico y el pobre pronóstico de pacientes con CVB. Creemos que procedimientos quirúrgicos más radicales en los cánceres invasores mejorarán los resultados

RESUMO

Se investigaron anticuerpos fijadores del complemento frente a los antígenos de Histoplasma Capsulatum, en el suero de 72 pacientes con síndrome respiratorio agudo y crónico, con signos anormales en radiografía de tórax, baciloscopía negativa y tratamiento antituberculoso. Resultaron 6 (8 por ciento) fijadores del complemento,, 6 (8 por ciento) anticomplementarios y 60 (84 por ciento) negativos. Dos pacientes mostraron títulos ò 1:4 frentes al antígeno micelial (AgM) y negativo al antígeno levaduriforme (AgL) y 4 pacientes mostraron títulos ó 1:8, frente a los dos antígenos. Un caso fue considerado como posible histoplasmosis "altamente sugestivo" y otro como histoplasmosis diseminada con evidencial histopatológica y cultural de histoplasmosis extrapulmonar. La edad de los pacientes de sueros positivos varió de 20-49 años y todos residieron temporalmente en zonas endémicas. Se comenta la utilidad clínica de los resultados y pruebas serológicas comunes.
