ABSTRACT

We present the design and synthesis of two new organic polymer films making use of a liquid-liquid interfacial amine-acid chloride polymerization strategy. One of them was additionally functionalized in situ by the anchoring of N-phenyl-phenothiazine through a monomer truncation strategy, which endowed it with photocatalytic activity. This photoactive film displays interesting luminescence phenomena that were used for the oxidation of a variety of sulphides to their corresponding sulfoxides and reduction of aryl bromines.

ABSTRACT

Introducción: Desde el inicio del brote de COVID-19 se han descrito diferencias entre las características clínicas, la evolución y el pronóstico de los pacientes de distintas localidades del Perú y del mundo. Objetivo: Determinar las características clínicas y epidemiológicas de la COVID-19 en pacientes de la comunidad y del Hospital Regional Lambayeque. Métodos: Se realizó un estudio de enfoque cuantitativo, nivel relacional y diseño observacional con datos secundarios. Se empleó la técnica de la documentación, se verificaron los datos recolectados en la ficha estandarizada de investigación clínica epidemiológica de COVID-19 del Ministerio de Salud del Perú. Resultados: De 4 463 pacientes analizados en el 36,4 % se detectó la presencia de SARS-CoV-2 y de éstos la mediana de edad fue de 40 años, siendo el sexo femenino el más frecuente (53,4 %). Del total de participantes, 23,7 % no registraron síntomas, sin embargo, los pacientes que declararon tos, dolor de garganta, malestar, fiebre/escalofrío, disnea, anosmia, ageusia y exudado faríngeo tenían más probabilidades de resultar infectados. De los positivos a la COVID-19, 40,2 % presentaban alguna comorbilidad. Las ocupaciones de policía/militar, ama de casa, estudiante y obrero de construcción civil tenían más probabilidades de dar positivo, mientras que, el personal sanitario tuvo 33 % menos probabilidad de infección. Conclusiones: Casi cuatro de cada 10 participantes tuvieron infección por SARS-CoV-2, existió predominio en los varones y personas en edad económicamente activa. La cuarta parte fueron asintomáticos. La tos, dolor de garganta, malestar y fiebre fueron los síntomas más frecuentes; menos frecuentes fueron la dificultad respiratoria, la anosmia, ageusia y exudado faríngeo, pero representaron mayor probabilidad de infección. Casi dos de cada 10 pacientes presentaron comorbilidad como problemas cardiovasculares, diabetes, asma y obesidad. En cuanto a las ocupaciones, el personal sanitario, policial y ama de casa fueron los grupos más afectados.


Introduction: Since the beginning of the outbreak, differences have been described between the clinical characteristics, evolution and prognosis of patients from different locations in Peru and the world. Objective: To determine the clinical and epidemiological characteristics of COVID-19 in patients from the community and the Lambayeque Regional Hospital. Methods: A study of quantitative approach, relational level and observational design with secondary data was carried out. The documentation technique was used, the data collected in the standardized COVID-19 clinical epidemiological investigation form of the Ministry of Health of Peru was verified. Results: Of 4,463 patients analyzed, 36.4 % had the presence of SARS-CoV-2, and of these the average age was 40 years, with the female sex being the most frequent (53.4 %). Of the total participants, 23.7 % had no symptoms, however, patients who reported cough, sore throat, malaise, fever/chills, dyspnea, anosmia, ageusia, and pharyngeal exudate were more likely to be infected with SARS- CoV-2. Of the positive patients for COVID-19, 40.2 % had some comorbidity. Likewise, the occupations of police/military, housewife, student and civil construction worker were more likely to test positive for COVID-19, while health personnel had a 33 % lower probability of SARS-CoV-2 infection. Conclusions: It is concluded that almost four out of 10 participants had SARS-CoV-2 infection, of which there was a predominance in men and people of economically active age. A quarter were asymptomatic. Cough, sore throat, malaise, and fever were the most frequent symptoms; likewise, respiratory distress, anosmia, ageusia, and pharyngeal exudate were less frequent, but represented a higher probability of infection. Almost two out of 10 patients had comorbidities such as cardiovascular problems, diabetes, asthma, and obesity. Regarding occupations, health personnel, police and housewives were the most affected groups.

ABSTRACT

La producción científica de las facultades de Ciencias Biológicas en el campo biomédico no ha sido evaluada en el Perú. El objetivo del estudio fue analizar las características de la producción científica y las contribuciones a las ciencias biomédicas de la Facultad de Ciencias Biológicas de la Universidad Nacional Pedro Ruiz Gallo, Perú (FCCBB-UNPRG). Se realizó un estudio descriptivo con enfoque bibliométrico; se consultaron tres bases de datos (Scopus, PubMed y LILACS) para buscar artículos que tuvieran, mínimo, un autor afiliado a la FCCBB-UNPRG. Se consignaron los siguientes datos: tipo de publicación, idioma, datos de autoría, financiamiento, año, área de publicación, datos de la revistas e instituciones colaborativas. Se realizó un análisis descriptivo y se elaboraron mapas de redes, utilizando el software VOSviewer. Se recopilaron 46 documentos; la mayoría son artículos (n = 36, 78,26 %), cartas (n = 9, 19,57 %) y reporte de casos (n = 1, 2,17 %); publicados en 30 revistas científicas, principalmente extranjeras. Existió mayor contribución en las áreas de microbiología, virología y parasitología. Se involucraron 42 instituciones colaborativas. Cerca del 90 % de las publicaciones no fueron financiadas. En los últimos años se observó un crecimiento en el número de publicaciones en diferentes áreas temáticas; esto demuestra el compromiso de la FCCBB-UNPRG con la investigación en el campo biomédico y la formación de investigadores. Se espera la implementación de políticas de investigación que involucren pautas y/o directrices para lograr un incremento sostenido de la producción científica.


The scientific production of the faculties of Biological Sciences in the biomedical field has not been evaluated in Peru. The objective of this study was to analyze the characteristics of the scientific production and the contributions to the biomedical sciences of the Faculty of Biological Sciences of Pedro Ruiz Gallo National University, Peru (FCCBB-UNPRG). A descriptive study with a bibliometric approach was carried out. Three databases (Scopus, PubMed, and LILACS) were consulted to search for articles that had, at least, one author affiliated with the FCCBB-UNPRG. The following data were recorded: type of publication, language, authorship data, funding, year, publication area, journal data, and collaborating institutions. A descriptive analysis was carried out and network maps were elaborated, using the VOSviewer software. Forty-six documents were retrived; the majority were articles (n = 36, 78.26%), letters (n = 9, 19.57%) and case reports (n = 1, 2.17%); published in 30 scientific journals, mainly foreign. Greater contribution was observed in microbiology, virology and parasitology. Fotry-two collaborative institutions were involved. About 90% of the publications were not funded. A growth in the number of publications in different thematic areas has been noted in recent years, which demonstrates the commitment of FCCBB-UNPRG to research in the biomedical field and the training of researchers. The implementation of research policies including guidelines and/or directives is expected to achieve sustained increase in scientific production.

ABSTRACT

Objetivos: determinar la frecuencia del gen mecA en Staphylococcus aureus resistente a meticilina (MRSA) aislados de pacientes atendidos en un hospital de tercer nivel en la región Cajamarca, Perú; asimismo, determinar cuál de los dos antibióticos usados como screening fenotípico tiene mayor utilidad para explicar la presencia de dicho gen. Métodos: se analizaron 71 aislamientos bacterianos provenientes de muestras del Hospital Regional Docente de Cajamarca, la identificación de S. aureus se llevó a cabo mediante el equipo MicroScan. El screening fenotípico para resistencia a meticilina se realizó mediante la técnica de difusión, con discos de cefoxitina y oxacilina. La extracción de ADN se realizó mediante shock térmico, la detección del gen mecA se realizó mediante reacción en cadena de la polimerasa. El análisis estadístico se realizó con el software SPSS v.25. Resultados: de los 71 aislados, 40 (56,3%) fueron MRSA portadores del gen mecA, la mayoría de estos aislamientos correspondieron a pacientes hospitalizados 22 (31,0%), siendo más frecuentes en muestras de secreción bronquial 27 (38,0%). El screening fenotípico con disco de cefoxitina predijo mejor la presencia del gen mecA [P=0,010; Exp(B)= 12,3] en comparación con el disco de oxacilina. Conclusiones: este estudio demostró alta frecuencia de MRSA mecA positivo en muestras de origen clínico, principalmente de pacientes hospitalizados. Es importante establecer medidas de vigilancia para identificar MRSA en todos los hospitales de la región.


Objective: to determine the frequency of the mecA gene in methicillin-resistant Staphylococcus aureus (MRSA) isolated from patients treated at a third-level hospital in the Cajamarca region, Peru; as well as, to determine which of the two antibiotics used as phenotypic screening is more useful in explaining the presence of said gene. Methods: 71 bacterial isolates were analyzed from samples obtained from the Hospital Regional Docente of Cajamarca. The identification of S. aureus was carried out using the MicroScan system. Phenotypic screening for resistance to methicillin was performed using the diffusion technique with cefoxitin and oxacillin discs. DNA extraction was performed by heat shock, mecA gene detection was performed through polymerase chain reaction. For data analysis, the statistical software SPSS v.25 was used. Results: from 71 isolates, 40 (56,3%) were MRSA carriers of the mecA gene, the majority of these isolates corresponded to hospitalized patients 22 (31,0%), being more frequent in bronchial secretion samples 27 (38,0%). Phenotypic screening with cefoxitin disc was a better predictor for the presence of the mecA gene [P=0,010; Exp(B)= 12,3] compared to the oxacillin disc. Conclusions: It is shown a high frequency of positive MRSA mecA in samples of clinical origin, mainly from hospitalized patients. It is important to establish surveillance guidelines to identify MRSA in all hospitals in the region.

ABSTRACT

El Síndrome de Guillain-Barré (SGB) es un raro trastorno del sistema nervioso, donde el sistema inmunológico del paciente ataca las neuronas periféricas en extremidades, causando debilidad muscular, pérdida de sensibilidad y a veces parálisis total. El origen de este trastorno, ha sido asociado a  respuestas inmunes desencadenadas luego de la  infección por Campylobacter spp.   Sin embargo, cuando no existe una causa evidente de la enfermedad, esta no suele ser investigada debido al mayor interés que requiere el tratamiento. Por ello, la mayoría de los casos  se notifican como origen idiopático.  Entre Enero y Marzo de 2016 a nivel mundial se registraron brotes del SGB en 8  países, vinculados con la emergencia del virus Zika. En Perú, desde finales de 2018 ha reportado con mayor frecuencia brotes de SGB y aunque no se ha confirmado asociación con Zika, el incremento de casos, la extensión geográfica donde se produjeron y las características clínicas de los pacientes afectados, tienen patrones comunes que llevan a sospechar un origen infeccioso principalmente de tipo viral . Por lo tanto, es importante conocer la evidencia científica actual acerca del rol que desempeñan algunos virus en este síndrome, permitiendo ampliar nuestro panorama epidemiológico con nuevas herramientas para hacer frente a esta enfermedad.


Guillain-Barré Syndrome (GBS) is a rare disorder of the nervous system, where the patient's immune system attacks the peripheral nerve cells in the arms and legs, causing muscle weakness, loss of sensation and sometimes total paralysis. The origin of this disorder has been associated with immune responses triggered by post-infection with Campylobacter spp. However, when there is no obvious cause of the disease, it is usually not investigated due to the greater interest in the treatment. Therefore, most cases are reported as idiopathic origin. Between January and March 2016 worldwide, GBS outbreaks were reported in 8 countries, linked to the emergence of the Zika virus. In Peru, since the end of 2018, outbreaks of GBS have been reported more frequently and although no association with Zika has been confirmed, the increase in cases, the geographical extension where they occurred and the clinical characteristics of affected patients, have common patterns that lead to suspect an infectious origin mainly of viral type. Therefore, it is important to know the current scientific evidence about the role that some viruses play in this syndrome, allowing us to expand our epidemiological picture with new tools to address this disease

ABSTRACT

Introducción: La viruela del simio es una enfermedad zoonótica viral, causada por el poxvirus del mismo nombre; endémica de África central y occidental. Sin embargo, su presencia se ha incrementado en otras regiones del mundo durante la última década en comparación con los 40 años anteriores. Objetivo. Describir y actualizar las características etiológicas, epidemiológicas y clínicas de la viruela del simio, así como discutir el potencial riesgo de diseminación internacional. Material y Métodos. Se realizó una revisión de literatura publicada en los últimos cinco años, utilizando los descriptores Medical Subject Headings. La búsqueda se hizo en las bases de datos MEDLINE / PubMed y LILACS, sin restricciones de idioma. Se excluyeron los estudios duplicados y aquellos que no se ajustaban al objetivo de la investigación, seleccionando 47 artículos. Resultados. El virus de la viruela del simio está emparentado con el de la viruela humana (erradicada en 1979). Se transmite desde un individuo enfermo mediante gotitas de fluido respiratorio, contacto con material de lesión cutánea y fluidos corporales; o mediante fómites contaminados. Después de 6 a 13 días de incubación aparecen los síntomas, semejantes al de la viruela humana: comenzando con un proceso febril agudo y seguido de erupción cutánea en rostro y cuerpo, que cura dejando cicatrices visibles. Conclusiones. Este virus puede ocupar el nicho ecológico dejado por el virus de la viruela humana. Actualmente se ha expandido a Europa y América, por lo que ya no debe considerarse una enfermedad limitada al África, sino una amenaza sanitaria para la salud pública global.


background:Monkeypox is a viral zoonotic disease caused by the poxvirus of the same name, endemic to central and western Africa. However, its presence has increased in other regions of the world during the last decade compared to the previous 40 years.To describe and update the etiologic, Objective.epidemiologic, and clinical features of simian pox, as well as to discuss the potential risk of international spread. . Areview of Material and Methods literature published in the last five years was performed using the descriptors Medical Subject Headings. The search was performed in the MEDLINE/PubMed and LILACS data bases, without language restrictions. Duplicate studies and those that did not fit the research objective were excluded, selecting 47 articles. Results.Simian smallpox virus is related to human smallpox virus (eradicated in 1979). It is transmitted from a sick individual by respiratory fluid droplets, contact with skin lesion material and body fluids; or by contaminated fomites. After 6 to 13 days of incubation, symptoms appear, similar to those of human smallpox: beginning with an acute febrile process and followed by a cutaneous eruption on the face and body, which heals leaving visible scars. This virus may occupy the Conclusions.ecological niche left by the smallpox virus. It has now spread to Europe and America, so it should no longer be considered a disease limited to Africa, but a health threat to global public health

ABSTRACT

Introducción: La variabilidad genética del SARS-CoV-2 ha incrementado notablemente desde que se declaró la pandemia, lo que le ha permitido representar un continuo desafió para las políticas de salud destinadas a su control. Objetivo. Describir la nomenclatura genómica utilizada para la comunicación general y científica sobre el SARS-CoV-2, así como describir las mutaciones, evolución, origen y variantes del virus. Material y Metodos. Se realizó una revisión narrativa de literatura, para el cual se realizó una búsqueda y análisis de la información hasta el 15 de diciembre de 2021. Se revisaron 74 fuentes seleccionados desde las bases de datos MEDLINE/ PubMed, SciELO, LILACS y páginas web oficiales; sin restricciones de idioma. Resultados. Las mutaciones son cambios en la secuencia de nucleótidos del genoma viral, que, al producir afectación de la dinámica epidemiológica en una población, dan lugar a variantes, y estos a su vez a clados diferenciados. Entre las variantes de interés destacan Lambda y Mu, identificadas por primera vez en Perú y Colombia, respectivamente. Mientras que, las variantes de preocupación, en orden cronológico, son la Alfa (británica), Beta (sudafricana), Gamma (brasilera), Delta (india) y recientemente Ómicron. Conclusiones. Se concluye que la diversidad genómica del SARS-CoV-2 se debe a su elevada tasa de mutaciones que pueden constituirse en variantes y clados. La mejor comprensión de esta diversidad permite tomar medidas de control más eficaces, guiando el desarrollo y uso de vacunas, terapias, diagnóstico y políticas en salud.


Introduction: The genetic variability of SARS-CoV-2 has increased markedly since the pandemic was declared, allowing it to pose a continuing challenge to health policies aimed at its control. Objective. To describe the genomic nomenclature used for general and scientific communication about SARS-CoV-2, as well as to describe the mutations, evolution, origin and variants of the virus. Material and Methods. A narrative literature review was conducted, for which a search and analysis of the information was performed until December 15, 2021. Seventy-four selected sources were reviewed from MEDLINE/PubMed, SciELO, LILACS databases and official web pages; without language restrictions. Results. Mutations are changes in the nucleotide sequence of the viral genome, which, by affecting the epidemiological dynamics in a population, give rise to variants, and these in turn to differentiated clades. Among the variants of interest are Lambda and Mu, identified for the first time in Peru and Colombia, respectively. Meanwhile, the variants of concern, in chronological order, are Alpha (British), Beta (South African), Gamma (Brazilian), Delta (Indian) and recently Omicron. Conclusions. It is concluded that the genomic diversity of SARS-CoV-2 is due to its high rate of mutations that can constitute variants and clades. A better understanding of this diversity allows more effective control measures to be taken, guiding the development and use of vaccines, therapies, diagnostics and health policies.

ABSTRACT

RESUMEN La capacidad de propagación y letalidad del SARS-CoV-2 en todo el mundo motiva la urgente necesidad de desarrollar una estrategia terapéutica apropiada para controlar los casos de COVID-19. El desarrollo de nuevos fármacos frente a este nuevo virus es apremiante debido a su rápida diseminación. Se han propuesto alternativas paralelas empleando fármacos ya disponibles para fines similares. Esta revisión describe el potencial antiviral de la ivermectina, así como sus mecanismos de acción frente a algunos virus, y discute su probable aplicación contra el SARS-CoV-2.


ABSTRACT The global spread and lethality of SARS-CoV-2 prompt the urgent need to develop an appropriate therapeutic strategy to control COVID-19 cases. The development of new drugs to fight this novel virus is urgent due to its rapid spread. Parallel alternatives have been proposed by using drugs already available for similar purposes. This review article describes the antiviral potential of ivermectin as well as its mechanisms of action against some viruses, and discusses its probable use to fight SARS-CoV-2.

ABSTRACT

RESUMEN Fundamento: el virus SARS-CoV-2 es responsable de la segunda pandemia del siglo XXI. Desde su aparición en China a finales de 2019, se asocia a neumonía y considera como un virus respiratorio más. Sin embargo, durante su diseminación global demuestra su capacidad para producir daño a otros órganos con manifestaciones clínicas nunca antes descritas para otros virus respiratorios. Objetivo: describir la evidencia científica que respalde el daño extrapulmonar directo producido por el virus SARS-CoV-2 en etapas tardías de la infección, que apoyan su naturaleza bifásica y distinta frente a otros virus respiratorios. Métodos: se realizó una búsqueda de artículos referente al tema en las bases de datos MEDLINE accedido desde PubMed, SciELO y LILACS. También se tuvieron en cuenta artículos publicados en los repositorios de preimpresión como medRxiv, BioRxiv. Mediante el gestor de búsqueda y administrador de referencias Mendeley, se eliminaron los duplicados y aquellos que no se ajustaban al objetivo del estudio, se seleccionaron 63 artículos para la revisión. Resultados: la evidencia sugiere que el SARS-CoV-2 tiene tropismo no solo limitado a las vías respiratorias. La progresión clínica de la COVID-19 presenta un curso bifásico, con manifestaciones de tipo gripal en la primera fase y episodios postagudos y persistentes en la fase tardía, ocasionados por el daño directo al sistema nervioso central, cardiovascular, endocrino y renal. Conclusiones: la infección por SARS-CoV-2 no debe considerarse solo como una infección aguda y circunscrita a las vías respiratorias.


ABSTRACT Background: the SARS-CoV-2 virus is responsible for the second pandemic of the 21st century. Since its appearance in China at the end of 2019, it has been associated with pneumonia and considered to be just another respiratory virus. However, during its global spread, it shows its ability to damage other organs with clinical manifestations never before described for other respiratory viruses. Objective: to describe the scientific evidence that supports the direct extra-pulmonary damage produced by the SARS-CoV-2 virus in late stages of infection, which supports its biphasic nature and different from other respiratory viruses. Methods: a search of the articles was carried out in the MEDLINE databases accessed from PubMed, SciELO and LILACS. Articles published in prepress repositories such as medRxiv, BioRxiv were also taken into account. Using the Mendeley reference manager and search manager, duplicates and those that did not meet the objective of the study were eliminated, selecting 63 articles for the present review. Results: the evidence suggests that SARS-CoV-2 has a tropism not only limited to the respiratory tract. The clinical progression of COVID-19 presents a biphasic course, with flu-like manifestations in the first phase and post-acute and persistent episodes in the late phase, caused by direct damage to the central nervous, cardiovascular, endocrine and renal systems. Conclusions: SARS-CoV-2 infection should not be considered only as an acute infection limited to the respiratory tract.

ABSTRACT

La actual pandemia producida por el coronavirus 2 del síndrome respiratorio agudo severo (SARS-CoV-2), ha impactado gravemente la economía y el sistema de salud en más de 190 países de todo el mundo en un evento sin precedentes, que desde su inicio ha dado lugar a innumerables informes de casos centrados en las manifestaciones sistémicas y respiratorias potencialmente mortales de la enfermedad. Sin embargo, aún no se conoce por completo el alcance de las posibles manifestaciones neurológicas causadas por este 2 nuevo virus. Comprender la interacción del SARS-CoV-2 con el sistema nervioso es esencial para evaluar las probables consecuencias patológicas a corto y largo plazo. Esta revisión busca reunir y discutir la evidencia sobre la ocurrencia de manifestaciones neurológicas y/o compromiso del sistema nervioso en pacientes infectados con SARS- CoV-2.


The current Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2) pandemic has severely impacted the economy and health care system in more than 180 countries around the world in an unprecedented event, which since its inception has resulted in countless case reports focusing on the potentially fatal systemic and respiratory manifestations of the disease. However, the full extent of possible neurological manifestations caused by this new virus is not yet known. Understanding the interaction of SARS-CoV-2 with the nervous system is essential to assessing likely short- and long-term pathologic consequences. This review seeks to gather and discuss evidence on the occurrence of neurological manifestations and/or nervous system involvement in SARS- CoV-2 infected patients.

ABSTRACT

BACKGROUND: Low-density lipoprotein cholesterol (LDL-C) contributes decisively to the development of cardiovascular disease (CVD). In the LYNX registry we determined the rate of achievement of the target value of LDL-C, the use of lipid-lowering therapy (LLT) and the predictive factors of not reaching the target in patients with stable coronary heart disease (CHD). METHODS: LYNX included consecutive patients with stable CHD treated at the University Hospital of Caceres, Extremadura (Spain) from September 2016 to September 2018, and those who must have an LDL-C target below 70 mg/dL according to the European Society of Cardiology (ESC) 2016 guidelines. The variables independently associated with the breach of the LDL-C objective were evaluated by multivariable logistic regression. RESULTS: A total of 674 patients with stable CHD were included. The average LDL-C levels were 68.3 ± 24.5 mg/dL, with 56.7% showing a level below 70 mg/dL. LLT was used by 96.7% of patients, 71.7% were treated with high-powered statins and 30.1% with ezetimibe. The risk of not reaching the target value of LDL-C was higher in women, in active smokers, and in those who had multivessel CHD or had atrial fibrillation. Patients with diabetes mellitus, those who took potent statins or co-administration treatment with ezetimibe were more likely to reach the target level of LDL-C. CONCLUSIONS: The treatment of dyslipidemia in patients with chronic CHD remains suboptimal; however, an increasing number of very high-risk patients achieve the LDL-C objective, although there is still enormous potential to improve cardiovascular outcome through the use of more intensive LLT.

ABSTRACT

Pulse wave velocity (PWV) is used for evaluating atherosclerosis; however, it is far from routine use. The authors validate a new device measuring PWV independently in each limb and explore its usefulness. Validity was studied in 40 patients. PWV was compared with endovascular measurements and comparisons were made between PWV in the extremities in 220 patients. The correlation between brachial PWV and endovascular catheter was (r=0.83, P<.001). The correlation coefficients for interobserver and intraobserver were r=0.87 and r=0.91, respectively. The sum of PWV in limbs allowed better stratification of patients according to cardiovascular risk. The validity and reproducibility of PWV measured with this device was good. The sum of PWV in extremities was a good index for stratifying patients according to vascular risk. These results suggest that the device is useful in the evaluation of arteriosclerosis and could possibly replace measurement devices available today.

ABSTRACT

Left ventricular pseudoaneurysm is usually associated with myocardial infarction and ventricular wall rupture, although it can also be associated with other pathological conditions. Rupture causes shock, and death if not repaired urgently. We report the very rare case of a man with coronary lesions that resulted in a silent myocardial infarction with rupture of the myocardial wall and the subsequent development of a large, posterolateral, left ventricular pseudoaneurysm. This was followed by rupture of the primary pseudoaneurysm and the consequent creation of a second pseudoaneurysm, which finally resulted in shock and death.
