Monkeypox (Mpox) is an emerging zoonotic disease with the potential for severe complications. Early identification and diagnosis are essential to prompt treatment, control its spread, and reduce the risk of human-to-human transmission. This study aimed to develop a clinical diagnostic tool and describe the clinical and sociodemographic features of 19 PCR-confirmed Mpox cases during an outbreak in a nonendemic region of northwestern Mexico. The median age of patients was 35 years, and most were male. Mpox-positive patients commonly reported symptoms such as fever, lumbago, and asthenia, in addition to experiencing painful ulcers and a high frequency of HIV infection among people living with HIV (PLWH)...

BACKGROUND: Takotsubo syndrome is a clinical syndrome characterized by an acute and transient left ventricular systolic dysfunction related to an emotional or physical stressful event. CASE PRESENTATION: During the Covid-19 pandemic, five cases of Takotsubo syndrome in hospitalized, mechanically ventilated patients due critical SARS-CoV-2 infection have been identified at our institution. Here we present the electrocardiographic, echocardiographic and angiographic characteristics of this case series...

We present the case of an 18-year-old man with aborted sudden cardiac death. His initial echocardiogram suggested an anomalous origin of the left coronary artery from the pulmonary artery. Diagnosis was confirmed with coronary angiography. He underwent Takeuchi procedure and fully recovered. A two-year follow-up echocardiogram showed a moderate supravalvular pulmonary stenosis related to the transpulmonary baffle. The presence of extensive collateral circulation should raise suspicion of ALCAPA. Postoperative surveillance in this group of patients needs to be oriented in finding complications such as supravalvular pulmonary stenosis, aortic and pulmonary valve insufficiency, and baffle obstruction and leaks...

To investigate the role of right ventricular free wall strain (RVFWSL) to predict low functional capacity in repaired tetralogy of Fallot (rTOF). We prospectively enrolled 33 patients with rTOF with moderate to severe PR who underwent rest and peak exercise echocardiography on a semisupine cycloergometer. Conventional function and strain imaging parameters of both ventricles were measured. Patients performing < 7 METS were defined to have low functional capacity. Logistic regression was used to identify parameters associated with low functional capacity...

Background: On May 2016, anticipating the rainy season from June to October in Mexico, we expected an increase in cases of Zika virus (ZIKV) infections. With the goal of identifying cases of GBS associated with ZIKV infection, a prospective joint study was conducted by a reference center for neurological patients and the Secretary of Health in Mexico City from July 2016 to November 2016. Methods: Serum, cerebrospinal fluid, urine, and saliva were tested by RT-PCR for ZIKV, dengue virus, and chikungunya virus in patients referred from states with reported transmissions of ZIKV infection, and with clinical symptoms of GBS according to the Brighton Collaboration criteria...

Chagas disease, which is caused by Trypanosoma cruzi, is considered to be the most serious parasitic disease in America. It is transmitted mainly by triatominae ("kissing bugs"). Mazzoti reported the first two human cases in Mexico. The form of transmission is by parasites entering the organism in feces of the insect, by blood transfusion, from mother to child, by organ transplant and laboratory accidents. In Mexico, 1.1 million people are estimated to be infected; the incidence in 2012 was 0.70 per 1,00,000 population...

Despite vaccination programs, influenza still represents a significant disease burden in Mexico. We conducted an observational, retrospective analysis to better understand the epidemiological situation of the influenza virus in Mexico. Analysis of the seasonal patterns of influenza A and B were based on the Directorate General of Epidemiology dataset of influenza-like illness(ILI), and severe acute respiratory infection(SARI) that were recorded between January 2010 and December 2013. Our objectives were 1) to describe influenza A and B activity, by age group, and subtype and, 2) to analyze the number of laboratory-confirmed cases presenting with ILI by influenza type, the regional distribution of influenza, and its clinical features...

INTRODUCTION: Three-vessel coronary artery disease is an advanced manifestation of atherosclerosis, with high prevalence in Mexico. OBJECTIVE: The aim of this study was to describe coronary risk factors in a group of patients with three-vessel coronary artery disease in Northwest Mexico. METHODS: A cross sectional study was conducted on a population with three-vessel coronary artery disease from May 2015 to February 2016. The disease was defined when ≥70% stenosis was present in each major epicardial coronary artery...

INTRODUCTION: Priapism is an uncommon sign and sometimes considered a diagnosis challenge into systemic disease; this is defined as ≥4 h continuous penile erection, without sexual stimulation. We state that this work has been reported in line with the SCARE criteria PRESENTATION OF CASE: A Mexican 52-year-old man was brought to the emergency room with priapism of six days of evolution. His medical history reported fatigue and waxy pallor had begun a month ago, the rest of interrogation was unremarked...

The baculovirus expression vector system (BEVS) is a popular manufacturing platform for the production of recombinant proteins, antiviral vaccines, gene therapy vectors, and biopesticides. Besides its successful applications in the industrial sector, the system has also played a significant role within the academic community given its extensive use in the production of hard-to-express eukaryotic multiprotein complexes for structural characterization for example. However, as other expression platforms, BEVS has to be continually improved to overcome its limitation and adapt to the constant demand for manufacturing processes that provide recombinant products with improved quality at higher yields and lower production cost...

Background: We report on the results of an entomovirological surveillance system of Aedes populations performed by the Ministry of Health of the central state of San Luis Potosí, Mexico. Methods: Indoor adult Aedes aegypti and Aedes albopictus pools collected at San Martín, Tamazunchale, Ciudad Valles, Metlapa, Ebano, Tamuin and Axtla during the dry season of 2016 were examined for the presence of dengue (DENV), chikungunya (CHIKV) and Zika (ZIKV) viruses using real-time PCR...

On 6 December 2013, the Pan American Health Organization (PAHO) and the World Health Organization (WHO) reported confirmation of the first two cases of indigenous transmission of chikungunya fever (CHIK) in the Region of the Americas on the island of Sint Maarten (Netherlands Antilles). For the period 2013-2014, a total of 25 627 confirmed autochthonous cases were distributed in 43 countries, with Mexico reporting 155 cases in five states. Information on cases of CHIK in Mexico was obtained from the database of the General Directorate of Epidemiology (Ministry of Health of Mexico)...

The influenza virus spreads rapidly through recurring seasonal outbreaks during the fall and winter. Our country has the Epidemiological Surveillance System for Influenza (SISVEFLU), in operation since 2006, which has records of 558 health units of Influenza. According to the information recorded in it, we can see that the 2010-2016 influenza seasons have a biannual behavior, and that in the 2010-2011, 2012-2013, and 2014-2015 seasons, the predominant viral subtype was A (H3N2), while in the 2011-2012, 2013-2014, and 2015-2016 seasons, the predominant subtype was A (H1N1) pdm09, which was associated with an increased number of influenza cases and deaths...

To assess the possible circulation of Zika virus (ZIKV) prior to the first documented case in Mexico, we reanalyzed the stored samples from the states of Veracruz and Yucatán, which were originally collected to test for dengue (DENV) and chikungunya (CHIKV) but were negative for these viruses despite the symptomatology. The samples were originally collected between the 30 and 46 epidemiological weeks (EW) when the ZIKV was not yet declared as a Public Health Emergency of International Concern (PHEIC). From the total 4016 negative samples, a total of one hundred samples, 50 from Veracruz (CHIK- DENV- ) and 50 from Yucatán (4 CHIK- DENV- and 46 CHIK- or DENV- ), were tested for Zika virus by using RT-PCR...
