Epidemiological Characteristics of Deaths from COVID-19 in Peru during the Initial Pandemic Response.

BACKGROUND AND AIM: Peru is the country with the highest mortality rate from COVID-19 globally, so the analysis of the characteristics of deaths is of national and international interest. The aim was to determine the epidemiological characteristics of deaths from COVID-19 in Peru from 28 March to 21 May 2020. METHODS: Deaths from various sources were investigated, including the COVID-19 Epidemiological Surveillance and the National System of Deaths (SINADEF). In all, 3851 deaths that met the definition of a confirmed case and had a positive result of RT-PCR or rapid test IgM/IgG, were considered for the analysis. We obtained the epidemiological variables and carried out an analysis of time defined as the pre-hospital time from the onset of symptoms to hospitalization, and hospital time from the date of hospitalization to death. RESULTS: Deaths were more frequent in males (72.0%), seniors (68.8%) and residents of the region of Lima (42.7%). In 17.8% of cases, the death occurred out-of-hospital, and 31.4% had some comorbidity. The median of pre-hospital time was 7 days (IQR: 4.0-9.0) and for the hospital time was 5 days (IQR: 3.0-9.0). The multivariable analysis with Poisson regression with robust variance found that the age group, comorbidity diagnosis and the region of origin significantly influenced pre-hospital time; while sex, comorbidity diagnosis, healthcare provider and the region of origin significantly influenced hospital time. CONCLUSION: Deaths occurred mainly in males, seniors and on the coast, with considerable out-of-hospital deaths. Pre-hospital time was affected by age group, the diagnosis of comorbidities and the region of origin; while, hospital time was influenced by gender, the diagnosis of comorbidities, healthcare provider and the region of origin.

Hospitalization, death, and probable reinfection in Peruvian healthcare workers infected with SARS-CoV-2: a national retrospective cohort study.

BACKGROUND: Peru has some of the worst outcomes worldwide as a result of the SARS-CoV-2 pandemic; it is presumed that this has also affected healthcare workers. This study aimed to establish whether occupation and other non-occupational variables were risk factors for possible reinfection, hospitalization, and mortality from COVID-19 in cohorts of Peruvian healthcare workers infected with SARS-CoV-2. METHODS: Retrospective cohort study. Healthcare workers who presented SARS-CoV-2 infection between March 1, 2020, and August 6, 2021, were included. Occupational cohorts were reconstructed from the following sources of information: National Epidemiological Surveillance System, molecular tests (NETLAB), results of serology and antigen tests (SICOVID-19), National Registry of Health Personnel (INFORHUS), and National Information System of Deaths (SINADEF). The incidence of probable reinfection, hospitalization, and death from COVID-19 was obtained in the cohorts of technicians and health assistants, nursing staff, midwives, dentists, doctors, and other healthcare workers. We evaluated whether the occupation and other non-occupational variables were risk factors for probable reinfection, hospitalization, and death from COVID-19 using log-binomial and probit binomial models, obtaining the adjusted relative risk (RRAJ). RESULTS: 90,398 healthcare workers were included in the study. Most cases were seen in technicians and health assistants (38.6%), and nursing staff (25.6%). 8.1% required hospitalization, 1.7% died from COVID-19, and 1.8% had probable reinfection. A similar incidence of probable reinfection was found in the six cohorts (1.7-1.9%). Doctors had a higher incidence of hospitalization (13.2%) and death (2.6%); however, they were also those who presented greater susceptibility linked to non-occupational variables (age and comorbidities). The multivariate analysis found that doctors (RRAJ = 1.720; CI 95: 1.569-1.886) had a higher risk of hospitalization and that the occupation of technician and health assistant was the only one that constituted a risk factor for mortality from COVID-19 (RRAJ = 1.256; 95% CI: 1.043-1.512). CONCLUSIONS: Peruvian technicians and health assistants would have a higher risk of death from COVID-19 than other healthcare workers, while doctors have a higher incidence of death probably linked to the high frequency of non-occupational risk factors. Doctors present a higher risk of hospitalization independent of comorbidities and age; likewise, all occupations show a similar risk of probable reinfection.

Arsenicism by Chronic Exposure to Mine Tailings in Peru: An Analysis of 17 Cases with Lesions on Skin and/or Annexes.

Objective: To characterize the epidemiology and clinical manifestations of arsenicism from chronic exposure to mine tailings in people with lesions on their skin and/or annexes in two mining districts in the highlands of Peru. Materials and Methods: In this case series study, we included 17 people that presented arsenical lesions in skin and annexes which were identified in two prior studies. We evaluated age, occupation, place of exposure, time of exposure, time of disease, manifestations on skin and annexes, location of lesions, severity, and 24-hour urine clearance of arsenic. Results: The average time of exposure was 16.5 ± 14.7 years, and the average length of disease was 9.8 ± 8.1 years. In this study, 70.6% were men, 41.2% were farmers and 17.6% were underage. The most frequent main manifestations in skin and annexes were plantar keratosis (23.5%), palmar (11.8%), palmoplantar (11.8%) and thoracic keratosis (5.9%). Other manifestations were palmoplantar keratosis with thoracic hyperpigmentation (17.6%), Mees' lines (17.6%) and hyper/hypopigmentation in thorax and back (11.8%). With relation to the severity of lesions, 35.3% were grade 1 (mild), 29.4 % were grade 0 (asymptomatic), 29.4 % were grade 2 (moderate), and 5.9% were grade 3 (severe). The median of 24-hour urine clearance of arsenic was 55 µg/L/24 hours. No cases of skin cancer were presented. Conclusion: The studied cases of arsenicism with lesions on skin and/or annexes by exposure to mine tailings present with differential characteristics in comparison to other forms of arsenicism such as less severity, lower urine clearance of arsenic, and absence of skin cancer cases.

Large Outbreak of Guillain-Barré Syndrome, Peru, 2019.

Outbreaks of Guillain-Barré syndrome (GBS) are uncommon. In May 2019, national surveillance in Peru detected an increase in GBS cases in excess of the expected incidence of 1.2 cases/100,000 population. Several clinical and epidemiologic findings call into question the suggested association between this GBS outbreak and Campylobacter.

Early transmission dynamics of COVID-19 in a southern hemisphere setting: Lima-Peru: February 29th-March 30th, 2020.

The COVID-19 pandemic that emerged in Wuhan China has generated substantial morbidity and mortality impact around the world during the last four months. The daily trend in reported cases has been rapidly rising in Latin America since March 2020 with the great majority of the cases reported in Brazil followed by Peru as of April 15th, 2020. Although Peru implemented a range of social distancing measures soon after the confirmation of its first case on March 6th, 2020, the daily number of new COVID-19 cases continues to accumulate in this country. We assessed the early COVID-19 transmission dynamics and the effect of social distancing interventions in Lima, Peru. We estimated the reproduction number, R, during the early transmission phase in Lima from the daily series of imported and autochthonous cases by the date of symptoms onset as of March 30th, 2020. We also assessed the effect of social distancing interventions in Lima by generating short-term forecasts grounded on the early transmission dynamics before interventions were put in place. Prior to the implementation of the social distancing measures in Lima, the local incidence curve by the date of symptoms onset displays near exponential growth dynamics with the mean scaling of growth parameter, p, estimated at 0.9 (95%CI: 0.9,1.0) and the reproduction number at 2.3 (95% CI: 2.0, 2.5). Our analysis indicates that school closures and other social distancing interventions have helped slow down the spread of the novel coronavirus, with the nearly exponential growth trend shifting to an approximately linear growth trend soon after the broad scale social distancing interventions were put in place by the government. While the interventions appear to have slowed the transmission rate in Lima, the number of new COVID-19 cases continue to accumulate, highlighting the need to strengthen social distancing and active case finding efforts to mitigate disease transmission in the region.

[Transforming the Peruvian birth information system]. / Transformando el sistema de información de nacimientos en el Perú

The On-Line Registration of Certificates of Live Births was developed in conjunction with the Ministry of Health of Peru and the National Registry of Identification and Civil Status. It is a free system that registers newborns in the delivery room itself which generates a real time certificate of live birth. This simplifies the procedures required to obtain the birth certificate and the National Identity Document for the newborn. This system has been implemented in 114 health centers in 21 regions from March 2012 to March 2013, and has registered 113,917 live births, providing accurate, timely and quality information about these births. This system is the main cornerstone of the health information system which helps obtain real time statistics for adequate and timely decision making in public health.

Transformando el sistema de información de nacimientos en el Perú / Transforming the peruvian birth information system

El Registro del Certificado de Nacido Vivo en Línea fue desarrollado gracias a un trabajo conjunto entre el Ministerio de Salud del Perú y el Registro Nacional de Identidad y Estado Civil. Se trata de un sistema gratuito que permite registrar a los recién nacidos en la misma sala de partos, y generar en tiempo real el certificado de nacido vivo, facilitando así el trámite necesario para la obtención del acta de nacimiento y del Documento Nacional de Identidad del recién nacido. Entre marzo de 2012 y marzo de 2013, este sistema se ha implementado en 114 establecimientos de salud, en 21 regiones, lo cual ha permitido el registro de 113 917 recién nacidos vivos, y ha proporcionado información precisa, oportuna y de calidad sobre estos nacimientos. Es así que este sistema se constituye como un eje central del sistema de información en salud que permite obtener estadísticas en tiempo real para una adecuada y oportuna toma de decisiones en salud pública.

A road traffic injury surveillance system using combined data sources in Peru.

A national hospital-based nonfatal road traffic injury surveillance system was established at sentinel units across Peru in 2007 under the leadership of the Ministry of Health. Surveillance data are drawn from three different sources (hospital records, police reports, and vehicle insurance reports) and include nonfatal road traffic injuries initially attended at emergency rooms. A single data collection form is used to record information about the injured, event characteristics related to the driver of the vehicle(s), and the vehicle(s). Data are analyzed periodically and disseminated to all surveillance system participants. Results indicated young adult males (15-29 years old) were most affected by nonfatal road traffic injuries and were most often the drivers of the vehicles involved in the collision. Four-wheeled vehicle occupants comprised one-half of cases in most regions of the country, and pedestrians injured in the event accounted for almost another half. The system established in Peru could serve as a model for the use of multiple data sources in national nonfatal road traffic injury surveillance. Based on this study, the challenges of this type of system include sustaining and increasing participation among sentinel units nationwide and identifying appropriate prevention interventions at the local level based on the resulting data.

Con el liderazgo del Ministerio de Salud, en el 2007 se estableció un sistema hospitalario nacional de vigilancia de traumatismos no mortales por accidentes de tránsito en unidades centinela de todo el Perú. Los datos de vigilancia se extraen de tres fuentes diferentes (registros hospitalarios, informes policiales e informes del seguro del vehículo) e incluyen los traumatismos no mortales por accidentes de tránsito atendidos inicialmente en las salas de urgencia. Se usa un único formulario de recopilación de datos para registrar la información sobre los heridos, las características del hecho relacionadas con el conductor o los conductores de los vehículos y del vehículo o los vehículos involucrados. Los datos se analizan periódicamente y se comunican a todos los participantes del sistema de vigilancia. Los resultados indicaron que los hombres adultos jóvenes (de 15 a 29 años) fueron los más afectados por traumatismos no mortales por accidentes de tránsito y con mayor frecuencia eran los conductores de los vehículos que participaron en la colisión. Los ocupantes de vehículos de cuatro ruedas representaron la mitad de los casos en la mayoría de las zonas del país y los peatones lesionados en el hecho representaron prácticamente la otra mitad. El sistema establecido en el Perú podría servir de modelo del uso de múltiples fuentes de datos para la vigilancia a nivel nacional de traumatismos no mortales por accidentes de tránsito. Según los resultados de este estudio, los retos de un sistema de este tipo consisten en mantener y aumentar la participación de las unidades de vigilancia de todo el país y determinar las intervenciones de prevención adecuadas en el nivel local según los datos obtenidos.

Patología del dedo gordo / Pathology of the big toe

No es fácil el hallar en los textos magistrales de dermatología, capítulos específicos que traten sobre patología que tenga su asiento en el dedo gordo (hallux, 1er artejo o dedo grande), sin embargo, son lesiones de consulta frecuente en la práctica diaria. De diversas etiologías, congénitas o adquiridas, infecciosas, metabólicas o tumorales, todas ellas pueden producir alteraciones en suanatomía y funcionabilidad. A continuación, presentamos un esbozo de clasificación sencilla de estas enfermedades, basándonos en la patología observada en nuestro departamento, en su respectiva iconografía y además realizamos una descripción de cada una de ellas.

ItÆs not easy to find textbooks of dermatology with chapters dedicated specifically to pathologies that affect the big toe. However, they are a frequent reason for consultation in our practice. Multiple conditions of different etiologies (congenital, acquired, tumoral, infectious, metabolic, etc) can compromise theiranatomy and function. We present a simple classification of these pathologies based on the observed associated clinical conditions and its respective iconography. In addition a brief description of these affections is also presented.
