Proctoporus machupicchu is a semi-fossorial lizard, which was discovered in two locations in the Historic Sanctuary of Machu Picchu (SHMP), Urubamba province, Cusco, Peru. The type series consists of two females and a male, however, the male paratype does not possess femoral pores which is incongruous with the males mentioned in the literature. In this paper, we report a new location outside the SHMP and re-examine the type series. Internally, the male paratype has no male vestiges (testicles and seminiferous ducts), so we conclude that there was an error in sexing. In addition, we report a new locality based on a juvenile male collected in the San Luis Private Conservation Area (ACP San Luis) of La Convención province. This new record increases the range of distribution of the species by 20.9km to the northeast and its altitudinal range from 2760 – 2800 to 2760 – 2966 m of altitude...

Antecedentes. El infarto de miocardio con elevación del segmento ST (IMCEST), es una de las principales causas de morbimortalidad a nivel global, la reperfusión adecuada del miocardio consigue disminuir las complicaciones de esta entidad. El objetivo del estudio fue describir las características clínicas y terapéuticas del IMCEST en el Perú y la relación de la reperfusión exitosa con los eventos adversos intrahospitalarios. Materiales y métodos. Cohorte prospectiva, multicéntrica de pacientes con IMCEST atendidos durante el año 2020 en hospitales públicos del Perú. Se evaluaron las características clínicas, terapéuticas y eventos adversos intrahospitalarios, además de la relación entre la reperfusión exitosa del infarto y los eventos adversos. Resultados. Se incluyeron 374 pacientes, 69,5% en Lima y Callao. La fibrinólisis fue usada en 37% de casos (farmacoinvasiva 26...

Erosive adenomatosis is a rare benign neoplasm that affects the nipple. Characterized by erosion, telorrhoea, telorrhagia, nodularity, pruritus and erythema, causing a progressive destructive process of the nipple, which can be confused with Paget's disease; which is why knowledge of this pathology is essential to avoid surgical overtreatment. We present the case of a 35-year-old patient diagnosed and treated with surgery, as well as a review of the literature on this entity. © 2023

Background: Different antigens are needed to characterize Plasmodium falciparum infection in terms of seroreactivity and targets for invasion inhibition, in order to guide and identify the proper use of such proteins as tools for the development of serological markers and/or as vaccine candidates. Methods: IgG responses in 84 serum samples from individuals with P. falciparum infection [classified as symptomatic (Sym) or asymptomatic (Asym)], or acute Plasmodium vivax infection, from the Peruvian Amazon region, were evaluated by enzyme-linked immunosorbent assays specific for a baculovirus-produced recombinant protein P. falciparum Merozoite Surface Protein 10 (rMSP10) and for non-EGF region selected peptides of PfMSP10 selected by a bioinformatics tool (PfMSP10-1, PfMSP10-2 and PfMSP10-3). Monoclonal antibodies against the selected peptides were evaluated by western blotting, confocal mi...

The aim of this study was to conduct a haematological evaluation of dogs and cats in Lima, Peru. A total of 460 blood samples (410 dogs and 50 cats) were collected between December 2017 and May 2018. The smears were stained with Wright and the reticulocytes were stained with Brilliant cresyl blue. Descriptive statistics were performed for quantitative variables in the erythroid, myeloid and lymphoid series, as well as the frequency analysis of qualitative variables between species indicator of type of anaemia and leukaemia, ability of medullary regeneration, abnormal morphological changes, out of physiological range and presence of extra and intracellular microorganisms. The most frequent alterations were normochromic normocytic anaemia (23.2% dog, 10% cat), megaloblastic anaemia (5.1% dog), severe hypochromic microcytic anaemia (4% cat), neutrophilic chronic myeloid leukaemia (7.1% dog,...
