Drug-induced pancreatitis: study of 38 patients. / Pancreatitis inducidas por fármacos: estudio de 38 pacientes.

INTRODUCTION: Acute pancreatitis (AP) is an inflammatory disease with multiple etiologies, and the emergence of complications. Between 0.1-5% of cases are attributed to drugs. The absence of specific characteristics complicates the diagnosis and treatment of drug-induced AP. Reviewing patients admitted with the diagnosis of drug-induced AP can provide information and improve its management. PATIENTS AND METHODS: This is a descriptive, observational, and retrospective study. All patients admitted to the Hospital Universitari de Bellvitge between June 2007 and March 2023 with suspected drug-induced AP were included. The data were obtained from the hospital pharmacovigilance program database. RESULTS: Thirty-eight patients with suspected drug-induced AP were identified, representing 0.62% of all adverse drug reactions (n=6.085). Of these, 65.8% (n=25) had a single suspected drug. The median latency period for the onset of adverse drug reactions was 160.5 days (IQR: 18-582 days), and the median hospital stay was 5 days (IQR: 3-7 days). Fifty-nine suspected drugs were identified, involving 26 active principles. Azathioprine and atorvastatin were the most frequent, with 9 cases each (15.2%), followed by enalapril with 8 cases (13.6%). Drug etiology was assessed in 23 cases (60.5%), and the suspected drug was discontinued in all cases. There was one fatal case documented (2.63%). CONCLUSION: This study can contribute to better understanding of drug-induced pancreatitis episodes. We propose a diagnostic algorithm that includes the assessment of the drug as a possible cause.

Mesenteric panniculitis: A comprehensive description of a rare disease.

Mesenteric panniculitis (MP) is a rare disease characterized by chronic inflammation and fibrosis of the mesenteric adipose tissue. It is a benign disease that is influenced by many factors, mainly abdominal trauma and surgery. At present, the pathogenesis and clinical characteristics of MP are still not clear. Most patients with MP are asymptomatic, few will present gastrointestinal symptoms, especially abdominal pain. The diagnosis of MP mainly relies on imaging, such as CT. Medicine treatment is unnecessary for asymptomatic patients, and the curative effect of glucocorticoids is effective in patients with symptom. In the absence of severe intestinal obstruction, surgical treatment should not be considered. The purpose of this paper is to systematically introduce and summarize the epidemiology, etiology, histopathology, clinical manifestations, diagnosis, treatment and prognosis of MP, so as to improve the understanding of this disease.

Acute kidney injury: the experience of a tertiary center of Pediatric Nephrology / Insuficiência renal aguda: experiência de um centro terciário de Nefrologia Pediátrica

ABSTRACT Introduction: Acute kidney injury (AKI) is an abrupt deterioration of kidney function. The incidence of pediatric AKI is increasing worldwide, both in critically and non-critically ill settings. We aimed to characterize the presentation, etiology, evolution, and outcome of AKI in pediatric patients admitted to a tertiary care center. Methods: We performed a retrospective observational single-center study of patients aged 29 days to 17 years and 365 days admitted to our Pediatric Nephrology Unit from January 2012 to December 2021, with the diagnosis of AKI. AKI severity was categorized according to Kidney Disease Improving Global Outcomes (KDIGO) criteria. The outcomes considered were death or sequelae (proteinuria, hypertension, or changes in renal function at 3 to 6 months follow-up assessments). Results: Forty-six patients with a median age of 13.0 (3.5-15.5) years were included. About half of the patients (n = 24, 52.2%) had an identifiable risk factor for the development of AKI. Thirteen patients (28.3%) were anuric, and all of those were categorized as AKI KDIGO stage 3 (p < 0.001). Almost one quarter (n = 10, 21.7%) of patients required renal replacement therapy. Approximately 60% of patients (n = 26) had at least one sequelae, with proteinuria being the most common (n = 15, 38.5%; median (P25-75) urinary protein-to-creatinine ratio 0.30 (0.27-0.44) mg/mg), followed by reduced glomerular filtration rate (GFR) (n = 11, 27.5%; median (P25-75) GFR 75 (62-83) mL/min/1.73 m2). Conclusions: Pediatric AKI is associated with substantial morbidity, with potential for proteinuria development and renal function impairment and a relevant impact on long-term prognosis.

RESUMO Introdução: Insuficiência renal aguda (IRA) é uma deterioração abrupta da função renal. A incidência de IRA pediátrica está aumentando em todo o mundo, em ambientes críticos e não críticos. Nosso objetivo foi caracterizar apresentação, etiologia, evolução e desfechos da IRA em pacientes pediátricos internados em um centro de atendimento terciário. Métodos: Realizamos estudo retrospectivo observacional de centro único de pacientes com idade entre 29 dias a 17 anos e 365 dias internados em nossa Unidade de Nefrologia Pediátrica, de janeiro de 2012 a dezembro de 2021, com diagnóstico de IRA. A gravidade da IRA foi categorizada de acordo com os critérios do Kidney Disease Improving Global Outcomes (KDIGO). Os desfechos considerados foram óbito ou sequelas (proteinúria, hipertensão ou alterações na função renal em avaliações de acompanhamento de 3 a 6 meses). Resultados: Incluímos 46 pacientes com idade mediana de 13,0 (3,5-15,5) anos. Cerca de metade (n = 24; 52,2%) apresentou um fator de risco identificável para o desenvolvimento de IRA. Treze pacientes (28,3%) eram anúricos; todos foram classificados como IRA KDIGO 3 (p < 0,001). Quase um quarto (n = 10; 21,7%) dos pacientes necessitaram de terapia renal substitutiva. Aproximadamente 60% (n = 26) apresentou pelo menos uma sequela, sendo proteinúria a mais comum (n = 15; 38,5%; mediana (P25-75) da relação proteína/creatinina urinária 0,30 (0,27-0,44) mg/mg), seguida de taxa de filtração glomerular (TFG) reduzida (n = 11; 27,5%; mediana (P25-75) da TFG 75 (62-83) mL/min/1,73 m2). Conclusões: A IRA pediátrica está associada à morbidade substancial, com potencial para desenvolvimento de proteinúria e comprometimento da função renal e impacto relevante no prognóstico de longo prazo.

Material and methods: a bibliographic search was carried out in five digital databases on peerreviewed articles from 2015 to the present. Conclusion: oral cancer is a frequent pathology that can cause serious consequences and sequelae in people who suffer it, an extensive knowledge of premalignant lesions among with an early diagnosis by the professional and a greater awareness of risk factors, play a fundamental role to prevent the establishment and/or progression of this pathology (AU)

Genetic study in young patients with chronic kidney disease stage G5 from unknown etiology. The GENSEN study design.

INTRODUCTION: Chronic kidney disease (CKD) of non-inherited etiology is one of the main causes of renal replacement therapy in our setting. Previous studies in other territories suggest that hereditary diseases could be one of the potential causes of this pathology, especially in younger patients. The GENSEN study will evaluate the presence of pathogenic genetic variants in subjects who have developed CKD category G5 before the age of 46 years, of non-inherited etiology. METHODS: Observational, prospective, multicenter study, which evaluates the diagnostic utility of massive high-throughput sequencing (HTS) directed to a set of genes, in the identification of the cause of CKD. Patients from all over Spain will be included, from whom a blood or saliva sample will be taken and a panel of 529 genes associated with hereditary kidney disease will be analyzed. This publication communicates the study protocol. CONCLUSION: The GENSEN study will make it possible to evaluate the diagnostic performance of the gene panel study in young subjects in our setting with the development of CKD category G5 without a clear cause. An etiological diagnosis would offer potential benefits for patients and relatives (targeted therapies, clinical trials, detection of extrarenal manifestations, evaluation of relatives for live donation, estimation of the risk of recurrence in the renal graft, genetic counseling, among others) and would allow to apply this genetic study to the nephrology of our country.

20% Autologous serum vs. 0.05% cyclosporine and preservative-free artificial tears in the treatment of Sjögren related dry eye / Soro autólogo a 20% versus ciclosporina a 0,05 e lubrificantes oculares sem conservantes no tratamento da síndrome do olho seco relacionada à Sjögren

ABSTRACT Purpose: To compare the 3-month results of treatment with 20% autologous serum or combination treatment with preservative-free artificial tears and 0.05% cyclosporine in patients with dry eye disease due to primary Sjögren's syndrome. Methods: A total of 130 eyes of 65 patients with newly diagnosed dry eye disease due to primary Sjögren's syndrome were included in the study. The patients were divided into two treatment groups: 66 eyes of 33 patients were assigned to the autologous serum treatment group, and 64 eyes of 32 patients were assigned to the combination treatment group. Schirmer test, tear break-up time and Ocular Surface Disease Index (OSDI) scores were recorded at pretreatment and at 3 months of treatment. Results: At 3 months of treatment, the mean Schirmer value and the mean tear break-up time were significantly higher in the combination treatment group (p<0.0001 and p=0.034, respectively). The OSDI score at 3 months was significantly lower in the autologous serum Group (p=0.004). When the two groups were evaluated separately, the improvements in Schirmer, tear break-up time test, and OSDI scores from before to after treatment were statistically significant: p<0.0001, p<0.001, and p<0.0001, respectively, for the authologus serum Group, and p<0.0001, p<0.001, and p<0.0001, respectively, for the combination treatment group. Conclusions: In short-term treatment of dry eye disease due to primary Sjögren's syndrome, treatment with autologous serum was significantly superior to -combination treatment with preservative-free artificial tears and 0.05% cyclosporine in terms of improvement in OSDI scores. Improvements in Schirmer test and tear break-up time scores were significantly superior in the group treated with preservative-free artificial tears and 0.05% cyclosporine.

RESUMO Objetivo: Comparar os resultados de 3 meses de soro autólogo a 20% com um tratamento combinado, ou seja, lubrificantes oculares sem conservantes e ciclosporina a 0,05% em pacientes com síndrome do olho seco devida à síndrome de Sjögren primária. Métodos: Foram incluídos no estudo 130 olhos de 65 pacientes recentemente diagnosticados com síndrome do olho seco devida à síndrome de Sjögren primária. Os pacientes foram divididos em dois grupos de tratamento, 66 olhos de 33 pacientes foram incluídos no grupo de tratamento com soro autólogo e 64 olhos de 32 pacientes foram incluídos no grupo de tratamento combinado com lubrificantes oculares sem conservantes e ciclosporina. Os resultados do teste de Schirmer e do tempo de ruptura do filme lacrimal e os índices de doença da superfície ocular (OSDI) foram registrados antes e depois de três meses de tratamento. Resultados: Três meses após o tratamento, o valor médio do teste de Schirmer foi mais alto com significância estatística no grupo do tratamento combinado com lubrificantes oculares sem conservantes e ciclosporina (p<0,0001) e o tempo de ruptura do filme lacrimal também foi significativamente maior nesse grupo (p=0,034). Também aos três meses, a doença da superfície ocular foi menor com significância estatística no grupo de tratamento com soro autólogo (p=0,004). Quando os dois grupos foram avaliados separadamente, a melhora no teste de Schirmer, o tempo de ruptura e a doença da superfície ocular antes e depois do tratamento tiveram diferenças estatisticamente significativas tanto no grupo de soro autólogo (p<0,0001, p<0,001 e p<0,0001, respectivamente) quanto no grupo de tratamento combinado (p<0,0001, p<0,001 e p<0,0001, respectivamente). Conclusões: No tratamento de curto prazo da síndrome do olho seco devida à síndrome de Sjögren primária, o tratamento com soro autólogo foi significativamente superior ao tratamento com lubrificantes oculares sem conservantes combinados com ciclosporina, em termos de melhora no doença da superfície ocular. As melhoras no teste de Schirmer e no tempo de ruptura do filme lacrimal foram significativamente maiores no grupo de tratamento combinado com lubrificantes oculares sem conservantes e ciclosporina.

Visual rehabilitation after LASIK complication: flap amputation, topo-guided surgery, and phacoemulsification

ABSTRACT We present a case of a patient complaining of monocular diplopia due to a decentered ablation after LASIK. The patient underwent a wavefront-guided retreatment, which resulted in an epithelial ingrowth complication. Additionally, the patient developed cataract, with cataract surgery requiring reliable biometric measurements. Therefore, we opted for corneal treatment and corneal surface regularization. Although we attempted to lift the flap and wash the interface initially, the procedure proved unsuccessful, thereby necessitating immediate flap amputation. Once the corneal surface was regularized in the seventh postoperative month, transepithelial photorefractive keratectomy was successfully performed to homogenize the ocular surface, thereby significantly improving the patient's corrected visual acuity and resolving monocular diplopia. The surface and corneal curvature stabilized by the fifth month after the procedure. Phacoemulsification was then performed along with the implantation of a toric monofocal lens, which was selected using an appropriate formula, resulting in an excellent uncorrected visual acuity.

Características epidemiológicas de la estrechez y estenosis uretral masculina en una institución de alta complejidad en Buenos Aires, Argentina / Epidemiological characteristics of male urethral stricture and stenosis in a highly complex institution in Buenos Aires, Argentina

Objetivo: Determinar la etiología actual y las características clínicas de la estrechez y estenosis de uretra masculina, en una institución de alta complejidad. Método: Estudio observacional, descriptivo de tipo transversal. Se recolectó información de 344 pacientes con estrechez o estenosis de uretra a los cuales se les realizó uretroplastia entre enero de 2011 y marzo de 2019. Para cada paciente se tuvo en cuenta la edad, la etiología, el sitio uretral comprometido, la longitud de la estrechez, procedimientos previos y la cirugía realizada. Resultados: La edad media fue 59,6 años (rango 14-90 años). La etiología más común fue la iatrogénica (68,1%), seguida de la inflamatoria (13,9%), idiopática (12,2%) y traumática (5,5%). De las causas iatrogénicas, el 39,2% fueron secundarias a instrumentación uretral, el 20,6% a cirugía endoscópica de próstata, el 4,3% poscirugía de hipospadias, un 2,3% otras y un 1,7% cirugía de próstata abierta. Al estratificar por edad, la etiología de la estrechez más común fue iatrogénica en los tres grupos etarios: en el grupo de 0-45 años con un 32,6%, en el grupo de 46-59 años con un 63,3% y en el grupo de mayores de 60 años con un 83,4%. Conclusión: La estrechez de uretra es una patología que cada vez se presenta con más frecuencia en la práctica urológica diaria, no es una enfermedad de los ancianos sino que involucra a todas las edades. Actualmente, la principal causa es la etiología iatrogénica, por lo cual estamos obligados a mejorar las estrategias de prevención

Objective: To determine the actual etiology and clinical characteristics of male urethral stricture and stenosis in a highly complexity institution. Method: Observational, descriptive cross-sectional study. Information was collected from 344 patients with urethral stricture or stenosis who underwent urethroplasty between January 2011 and March 2019. Age, etiology, compromised urethral site, length of the stricture, previous procedures and surgery performed were considered for each patient. Results: The median age was 59.6 years (range 14-90 years). The most common etiology was iatrogenic 68.1%, followed by inflammatory 13.9%, idiopathic 12.2% and traumatic 5.5%. Of the iatrogenic causes, 39.2% were secondary to urethral instrumentation, 20.6% endoscopic prostate surgery, 4.3% post-hypospadias surgery, 2.3% other, and 1.7% open prostate surgery. When stratifying by age, the most common etiology of stricture was iatrogenic in all three age groups: in the 0-45 years group (32.6%), in the 46-59 years group (63.3%) and in the group of over 60 years (83.4%). Conclusion: Urethral stricture is a pathology that occurs more and more frequently in daily urological practice, it is not a disease of the elderly but involves all ages. Currently, the main cause is iatrogenic etiology, for which reason we are obliged to improve prevention strategies

Percepción temporal de síntomas de disfagia en una cohorte de pacientes con disfagia orofaríngea neurogénica

Introducción: La disfagia resulta de varios mecanismos fisiopatológicos donde sus síntomas no son estáticos ni homogéneos en las personas, especialmente cuando existe disfagia orofaríngea neurogénica. Objetivo: Conocer la percepción y comportamiento en el tiempo de síntomas de disfagia mediante el instrumento Eating Assessment Tool-10 (EAT-10) en pacientes con disfagia orofaríngea neurogénica, con el fin de visualizar la dinámica clínica de esta forma de disfagia. Metodología: Estudio observacional tipo cohorte en pacientes con disfagia orofaríngea neurogénica de causas neurológicas y neuromusculares, con seguimiento a tres y seis meses y diligenciamiento del EAT-10 al momento basal, tercer y sexto mes. Resultados: Un total de 90 personas con evaluación basal, de las cuales el 56,7 % (51/90) lograron seguimiento al tercer mes y 25,6 % (23/90) al sexto mes. Los síntomas de disfagia con mayor autopercepción en los tres momentos fueron la dificultad para tragar sólidos, sensación de comida pegada en garganta y tos al comer. La odinofagia no fue un síntoma habitualmente percibido. La puntuación total del EAT-10 estuvo entre 16,61 ± 9 y 18,1 ± 9,5 puntos en general. En pacientes con seguimiento completo se observó variación en la autopercepción para tragar líquidos y pastillas. Se observó variación del puntaje al ajustarlo por recepción de terapias. Discusión: Las enfermedades neurológicas y neuromusculares impactan directamente la deglución con gravedad entre leve a profunda, donde la autopercepción de síntomas deglutorios es dinámica, pero con síntomas cardinales de disfagia orofaríngea en el tiempo. Conclusiones: El reconocimiento y seguimiento de síntomas de disfagia deben ser aspectos usuales en la atención de pacientes con enfermedades neurológicas y neuromusculares.

Introduction: Dysphagia results from several pathophysiological mechanisms where its symptoms are not static or homogeneous in people, especially when there is neurogenic oropharyngeal dysphagia. Objective: To know the perception and behavior over time of symptoms of dysphagia using the Eating Assessment Tool-10 (EAT-10) in patients with neurogenic oropharyngeal dysphagia to visualize the clinical dynamics of this form of dysphagia. Methodology: Observational cohort study in patients with neurogenic oropharyngeal dysphagia of neurological and neuromuscular causes with, follow-up at three and six months, and completion of the EAT-10 at baseline, third and sixth month. Results: A total of 90 people with baseline evaluation were included, of whom 56.7% (51/90) achieved follow-up at the third month and 25.6% (23/90) at the sixth month. Symptoms of dysphagia with greater self-perception at all three moments were difficulty swallowing solids, sensation of food stuck in the throat and coughing when eating. Odynophagia was not a commonly perceived symptom. The total score of the EAT-10 was between 16.61±9 and 18.1±9.5 points in general. In patients with complete follow-up, variation in self-perception of swallowing liquids and pills was observed. Variation of the score when adjusting for the reception of therapies. Discussion: Neurological and neuromuscular diseases directly impact swallowing with mild to profound severity, where self-perception of swallowing symptoms is dynamic, but with cardinal symptoms of oropharyngeal dysphagia over time. Conclusions: The recognition and monitoring of dysphagia symptoms should be usual aspects in the care of patients with neurological and neuromuscular diseases.

Caracterización de los aspectos etiológicos, fisiopatológicos, clínicos y terapéuticos de la sepsis y shock séptico / Characterization of the etiological, physiopathological, clinical and therapeutic aspects of sepsis and septic shock

La sepsis es un síndrome clínico basado en una compleja y dinámica interacción entre patógeno y huésped. La identificación de diferentes fenotipos y la heterogeneidad de la sepsis obligan a cambiar paradigmas en el diagnóstico-tratamiento. El shock séptico o septicémico se define como la hipotensión inducida por sepsis que persiste a pesar de la reanimación adecuada con fluidos, acompañada de alteraciones de la perfusión o disfunción de órganos. O la necesidad de fármacos vasoactivos para corregir la presión arterial. Es un tipo de shock distributivo, con reducción de las resistencias vasculares sistémicas y generalmente aumento del gasto cardíaco. En los últimos años, ha evolucionado la atención de la sepsis con especial enfoque shock séptico (SS) por su gravedad y su mayor morbimortalidad. En consideración a lo anterior, esta revisión tiene el propósito de realizar la caracterización de esta patología en los aspectos etiológicos, fisiopatológicos, clínicos y terapéuticos más importantes

Sepsis is a clinical syndrome based on a complex and dynamic interaction between pathogen and host. The identification of different phenotypes and the heterogeneity of sepsis requires a paradigm shift in its diagnosis and treatment. Septic shock is defined as a sepsis-induced hypotension that persists despite adequate fluid resuscitation, accompanied by perfusion abnormalities or organ dysfunction. It may also involve the need for vasopressor drugs to correct blood pressure. It is a type of distributive shock, characterized by reduced systemic vascular resistance and typically increased cardiac output. In recent years, the management of sepsis has evolved with a special focus on septic shock (SS) due to its severity and higher morbidity and mortality. Considering the above, this review aims to characterize this condition in terms of its etiological, pathophysiological, clinical, and therapeutic aspects

Distribution and Etiology of Facial Fractures in Patients Admitted by the Oral and Maxillofacial Specialty at an Emergency Hospital in Recife / Distribuição e Etiologia das Fraturas Faciais em Pacientes Internados pela Especialidade Buco-Maxilo-Facial em um Hospital de Emergência de Recife

Among the traumas, those that affect the oral and maxillofacial region stand out considerably, due to their high complexity and the fact that they affect a bodily region with great physiological, aesthetic and social importance. This study aimed to characterize the facial traumas that generate fractures, specifying their distribution and etiology, in patients who were hospitalized. For this, a cross sectional study was carried out on secondary data, in which 407 medical records of patients hospitalized by the Oral and Maxillofacial Surgery Service of the public network at Hospital da Restauração Governador Paulo Guerra - HR, in the city of Recife-Pernambuco, were collected, from which 130 medical records were selected whose reason for admission into the hospital was trauma to the bones of the face, hospitalized in the period between January 1st and December 31st, 2021, representing the sample of this study. The results regarding the distribution of fractures showed that the mandible was the most affected bone (66% of the cases), followed by the maxilla with 35%, the zygoma with 29%, the orbit with 15% and the bones of the nose in 12%. As for the etiology, car accident was responsible for the highest frequency of fractures with 29%, followed by physical aggression, with 22%, Firearm Projectile (16%), falls (16%), others (10%). It can be concluded that, in the period studied, the mandible was the most affected bone by fractures and traffic accidents were the main causes of facial fractures requiring hospitalization, and men being five times more affected than women.

Entre os traumas, os que acometem o campo buco-maxilo-facial se destacam consideravelmente, devido a sua alta complexidade e pelo fato de atingirem uma região corporal com grande importância fisiológica, estética e social. Este estudo teve como objetivo caracterizar os traumas faciais geradores de fraturas, especificando sua distribuição e etiologia, em pacientes que foram hospitalizados. Para isto, foi desenvolvido um estudo transversal em dados secundários, no qual foram coletados 407 prontuários de pacientes internados pelo Serviço de Cirurgia Buco-maxilo-facial da rede pública no Hospital da Restauração Governador Paulo Guerra ­ HR, na cidade do Recife-Pernambuco, dos quais foram selecionados 130 prontuários cujo motivo da internação foi trauma em ossos da face, internados no período entre 01 de janeiro a 31 de dezembro de 2021, representando a amostra deste trabalho. Os resultados quanto a distribuição das fraturas demonstrou que a mandíbula foi o osso mais atingido (66% dos cases), seguido pela maxila com 35%, o zigoma com 29%, órbita com 15% e Ossos Próprios de Nariz em 12%. Quanto a etiologia, o acidente automobilístico foi o responsável pela maior frequência das fraturas com 29%, seguida por agressão física, com 22%, Projétil de Arma de Fogo (16%), quedas (16%), outros (10%). Pode-se concluir que, no período estudado, a mandíbula foi o osso mais acometido pelas fraturas e os acidentes de trânsito foram os maiores causadores de fraturas faciais com necessidade de internamento, sendo os homens cinco vezes mais acometidos do que as mulheres.

Detección molecular de patógenos en deposiciones en niños consultantes por diarrea aguda en Servicios de Urgencia / Molecular detection of pathogens in stool samples of children consulting for acute diarrhea in emergency services

INTRODUCCIÓN: La diarrea aguda continúa siendo una de las principales causas de morbilidad en niños; sin embargo, el diagnóstico etiológico presenta limitaciones dada la baja sensibilidad de los métodos tradicionales. OBJETIVO: Describir los microorganismos identificados en niños que acudieron al Servicio de Urgencia (SU) de un hospital universitario en Santiago, Chile, por diarrea aguda y a los que se le solicitó panel molecular gastrointestinal. MÉTODOS: Se revisaron fichas clínicas y resultados de panel gastrointestinal realizados entre junio de 2017 y marzo de 2020. RESULTADOS: Se incluyeron 198 pacientes, edad promedio de 54,5 meses y 60,6% (120/198) de sexo masculino. La positividad del panel fue de 78,8% (156/198) con 35,3% (55/156) de las muestras polimicrobianas. Se identificaron 229 microorganismos, de los cuales 72,9% (167/229) corresponden a bacterias, 25,8% (59/229) a virus y 1,3% (3/229) a parásitos. Destacaron Campylobacter spp. y Escherichia coli enteropatógena (ECEP) como las bacterias más frecuentemente identificadas. Los pacientes con detección de Campylobacter spp. presentaron con mayor frecuencia fiebre (p = 0,00). ECEP se aisló principalmente (82,5%) en muestras polimicrobianas. DISCUSIÓN: Los resultados enfatizan el potencial que poseen los estudios moleculares para mejorar el diagnóstico etiológico de la diarrea, pero a la vez llevan a cuestionar el rol patogénico de algunos microorganismos identificados.

BACKGROUND: Acute diarrhea continues to be one of the main causes of morbidity in children, however the etiologica diagnosis presents limitations given the low sensitivity of traditional methods. AIM: To describe the microorganisms identified in children who attended the emergency department (ED) in Santiago, Chile, due to acute diarrhea and to whom a gastrointestinal panel was requested as part of their study. MATERIAL AND METHODS: Clinical records and results of the gastrointestinal panel carried out between June 2017 and March 2020 were reviewed. RESULTS: 198 patients were included, the average age was 54.5 months and 60.6% (120/198) were males. Positivity was 78.8% (156/198) with 35.3% (55/156) of the samples being polymicrobial. 229 microorganisms were identified, of which 72.9% (167/229) corresponded to bacteria, 25.8% (59/229) to viruses, and 1.3% (3/229) to parasites. Campylobacter spp. and enteropathogenic Escherichia coli (EPEC) were the most frequently identified bacteria. Patients with detection of Campylobacter spp. presented a higher frequency of fever (p = 0.00). EPEC was isolated in 82.5% of the cases in polymicrobial samples. DISCUSSION: The results emphasize the potential of molecular studies to improve the etiological diagnosis of diarrhea and at the same time lead to question the pathogenic role of some microorganisms.

ACV isquémico en población joven: ¿existe un enfoque diferencial del riesgo? / Ischemic stroke in a young population: is there a differential approach to risk factors?

Introducción: El ataque cerebrovascular isquémico en el adulto joven se define como aquel que ocurre en la población entre los 18 y los 55 años, y representa el 15-18 % de todos los ACV isquémicos. Los factores de riesgo en jóvenes son comunes a los encontrados en adultos mayores. El objetivo de este trabajo es describir las características clínicas y los factores de riesgo de una población menor de 55 años con ACV isquémico atendida en un centro de referencia hospitalario en Colombia. Materiales y métodos: Estudio descriptivo, retrospectivo de corte transversal en pacientes entre los 18 y los 55 años; se incluyeron 100 pacientes sobrevivientes a un primer ACV isquémico agudo confirmado por neuroimagen, atendidos entre enero de del 2019 y noviembre del 2021. Resultados: De 1023 pacientes con diagnóstico de ACV isquémico agudo, el 9,8 % fueron adultos jóvenes. La media de edad fue de 45 ± 8,7 años, y el 59 % de estos pacientes fueron hombres. Discusión: Los factores de riesgo "tradicionales" se presentan en la mayoría de los jóvenes con ACV isquémico. La hipertensión arterial se mantiene como el antecedente más frecuente. Las mujeres presentan eventos de mayor severidad y peor desenlace funcional. Conclusión: Los pacientes mayores de 45 años tienen un perfil de factores de riesgo similar a lo observado en adultos mayores con ACV, mientras que en los menores de 45 años se encuentra un perfil de factores de riesgo diferente que plantea un diagnóstico etiológico particular de esta población.

Introduction: Ischemic stroke in young adults is defined as occurring in individuals between the ages of 18 and 55, representing 15-18 % of all ischemic strokes. Risk factors in young adults are similar to those found in older adults. The objective of this study is to describe the clinical characteristics and risk factors of a population under 55 years of age with ischemic stroke treated at a hospital reference center in Colombia. Materials and methods: Descriptive, retrospective cross-sectional study in patients between 18 and 55 years old. A total of 100 patients between 18 and 55 years old who survived a first confirmed acute ischemic stroke, as confirmed by neuroimaging, were included. The study period was from January 2019 to November 2021. Results: Out of 1023 patients diagnosed with acute ischemic stroke, 9.8 % occurred in young adults. The mean age was 45 ± 8.7 years, of which 59 % were male. Discussion: "Traditional" risk factors are present in the majority of young adults with ischemic stroke. Hypertension remains the most common antecedent. Women experience more severe events and worse functional outcomes. Conclusion: Patients over 45 years old have a risk factor profile similar to what is observed in older adults with stroke, while in those under 45, a different risk factor profile is found, which poses a particular etio-logical diagnosis for this population.

[Paget's disease of bone: 1877-2023. Etiology, and management of a disease on epidemiologic transition]. / Enfermedad ósea de Paget: 1877-2023. Etiología y abordaje de una enfermedad en transición epidemiológica.

Paget's disease of bone is characterized by the alteration, in one or several bone locations, of the equilibrium between bone formation and bone resorption. This imbalance results in a disorganized, widened bone, in many cases with increased bone density, although more fragile. A genetic predisposition for Paget's disease of bone could explain between 5% and 40% of the cases. Different environmental factors should explain the rest of the cases. Paget's disease of bone was classically considered the second most common metabolic bone disease. However, in recent decades there has been a marked decrease in both incidence and clinical severity. These changes have led to believe that the influence of some environmental factor may have diminished or even disappeared. This decrease in incidence should not be an excuse for abandoning Paget's disease of bone research, but rather it should be the reason to remain searching to try to understand better its pathogenesis.

Presencia de Bipolaris cookei en sorgo en el centro oeste de Entre Ríos, Argentina / Occurrence of Bipolaris cookei on sorghum in central-western Entre Ríos, Argentina

Resumen En la provincia de Entre Ríos, Argentina, el sorgo se cultiva con destino a grano y forraje, contribuyendo además en los sistemas productivos a mantener la estabilidad estructural del suelo. En verano de 2018, en dos híbridos comerciales de sorgo granífero implantados en la EEA Paraná del INTA (Oro Verde, Entre Ríos), se observaron manchas foliares castaño oscuras, elípticas a ovaladas, regulares a algo irregulares, a veces con márgenes difusos, de 3 x 5 mm aproximadamente, en los estratos medio e inferior de las plantas. Asimismo, en verano de 2019, en dos híbridos pre comerciales y en un híbrido comercial, además de los síntomas anteriormente mencionados, se detectaron puntuaciones y manchas púrpuras con márgenes irregulares y difusos y delimitadas por las nervaduras en las hojas más jóvenes, dando el aspecto de un "salpicado" foliar. El objetivo del trabajo fue caracterizar e identificar el organismo causal de una enfermedad foliar presente en híbridos de sorgo granífero del centro oeste de Entre Ríos. Los síntomas observados en las muestras provenientes de campo y los producidos en las pruebas de patogenicidad, las características morfológicas de las colonias, así como la de los conidios desarrollados in vivo e in vitro, coincidieron con las descripciones realizadas para Bipolaris cookei (= B. sorghicola), organismo causal de la "mancha por Bipolaris" o "mancha difusa" del sorgo. La información obtenida contribuye al conocimiento de este patosistema en la región productora de sorgo de Entre Ríos.

Abstract In the province of Entre Ríos, Argentina, sorghum is grown for grain and forage, and also contributes to maintaining soil structural stability in production systems. In summer 2018, in two commercial hybrids of grain sorghum planted at the Paraná Agricultural Experimental Station of INTA (Oro Verde, Entre Ríos), dark brown, elliptical to oval, regular to somewhat irregular leaf spots, sometimes with diffuse margins, measuring approximately 3 x 5 mm, were observed in the middle and lower strata of the plants. Also, in summer 2019, on two pre-commercial hybrids and one commercial hybrid, in addition to the symptoms mentioned above, specks and purple spots with irregular and diffuse margins and delimited by the veins were detected on the youngest leaves, giving the appearance of a foliar "splash". The objective of this work was to characterize and identify the causal organism of a foliar disease present in grain sorghum hybrids from central-western Entre Ríos. The symptoms observed in field samples and those produced in pathogenicity tests, the morphological characteristics of the colonies, as well as those of the conidia developed in vivo and in vitro, coincided with the descriptions made for Bipolaris cookei (= B. sorghicola), the causal organism of the "target leaf spot" of sorghum. The information obtained contributes to the knowledge of this pathosystem in the sorghum producing region of Entre Ríos.

Impacto de las exacerbaciones en la enfermedad pulmonar obstructiva crónica / Impact of Exacerbations on Chronic Obstructive Pulmonary Disease

La enfermedad pulmonar obstructiva crónica (EPOC) es la tercera causa de muerte en todo el mundo. Sin embargo, ante la falta de herramientas diagnósticas precisas en el primer nivel de atención médica, como la espirometría, es difícil determinar la prevalen-cia real de la EPOC.Por otro lado, la falta de una definición clara y precisa de las exacerbaciones de la EPOC hace que se subestime su impacto en la salud pública; habitualmente, los pacien-tes con EPOC que cursan una exacerbación retrasan la búsqueda de atención médica inmediata porque se acostumbran al deterioro asociado a la enfermedad o lo confun-den con cambios por la edad avanzada. Esto puede provocar un aumento de la mor-bilidad y la mortalidad, asimismo, mayor utilización de los recursos sanitarios y mayor carga económica. Por lo tanto, es importante sensibilizar sobre la importancia del diagnóstico temprano y el tratamiento adecuado de las exacerbaciones de la EPOC, del mismo modo que el mayor conocimiento público de los síntomas, las causas y los factores de riesgo de la EPOC. Con ello, se podrán aplicar estrategias de prevención, diagnóstico y tratamiento más eficaces que mejoren la calidad de vida de los pacientes y disminuyan la carga de la enfermedad para la sociedad.Esta revisión ofrece un análisis crítico de la definición más reciente y esboza las impli-caciones del comportamiento de las exacerbaciones, su impacto en los distintos ám-bitos del sistema sanitario, así como en las diferentes esferas de la vida de los pacien-tes con EPOC.

Chronic Obstructive Pulmonary Disease (COPD) is a common disease and the third leading cause of death worldwide. However, due to the lack of accurate diagnostic tools at the first level of care, such as spirometry, the true prevalence of COPD is difficult to determine.In addition, the lack of a clear definition of COPD exacerbations means that its pub-lic health impact is underestimated. Patients with COPD often do not seek immediate medical attention because they become used to the deterioration associated with the disease. This can lead to increased patient morbidity and mortality, as well as increased utilization of healthcare resources and higher economic costs. Therefore, it is important to promote greater awareness of the importance of early di-agnosis and proper management of COPD exacerbations, as well as increased public awareness of COPD symptoms, etiologic agents, and risk factors.By better understanding COPD exacerbations, more effective prevention, diagnosis and treatment strategies can be implemented to improve the quality of life of patients and reduce the burden of the disease on society.This review aims to provide a critical analysis of the most recent definition and to out-line the implications of the behavior of COPD exacerbations and their impact on the dif-ferent settings of the health care system, as well as on the different spheres of patients' lives.

Metastatic and aggressive renal cell carcinoma mimicking a unilateral choroidal tuberculoma / Carcinoma de células renais metastático grave mimetizando tuberculoma de coroide unilateral

ABSTRACT Ocular metastases from systemic tumors are uncommon. The choroid is the most frequent target, with a preference for elderly individuals. Lung cancer is the predominant primary tumor that metastasizes to the eyes in males, although other ocular conditions such as uveitis and retinal lesions can mimic secondary tumor implants in ocular tissues. On fundoscopy, choroidal metastasis resembles other infectious processes, especially choroidal tuberculoma. Therefore, patients presenting with choroidal masses should undergo detailed clinical examinations, especially if the mass is the first manifestation of a systemic and severe disease. In this report, we describe a young man with a metastatic choroidal tumor secondary to papillary renal cell carcinoma mimicking a unilateral choroidal tuberculoma.

RESUMO A disseminação metastática ocular de tumores sistêmicos é incomum, ocorrendo principalmente na coroide e em pacientes idosos. O câncer de pulmão é considerado o principal tumor metastático ocular em homens, contudo, outras doenças oculares, como as uveítes e lesões retinianas, podem mimetizar os implantes secundários tumorais nos tecidos oculares. O aspecto fundoscópico das neoplasias da coroide pode apresentar similaridade com outros processos infecciosos, especialmente o tuberculoma de coroide. Dessa forma, a investigação clínica detalhada é de grande importância no diagnóstico de pacientes com massas coroideanas, especialmente quando configuram a primeira manifestação de uma doença sistêmica e grave. Relatamos um caso raro de metástase coroideana como primeira manifestação clínica do carcinoma de células renais em um homem jovem, mimetizando um tuberculoma de coroide.
