EDITORIAL
Los tiempos de la “nueva normalidad” están constituyendo una época, cuando menos, nada normal. Algunas de sus características, por todos conocidas y comentadas, son la incertidumbre, la rigidez, la crítica, y por qué no decirlo, la contradicción. Contradicción en las normas, en los protocolos, en la información… En las normas que cambian y se contraponen a lo largo del tiempo, en los protocolos que chocan con una realidad en la que su desarrollo no siempre es posible, en la información muchas veces poco clara y, de sentencias y declaraciones de escasa base científica y pobres evidencias.

CLINICAL LABORATORY REPORTS IN AUTOMATED URINARY BIOCHEMISTRY: A PROPOSAL

Written by Macarena Díaz Giménez | Enrique Rodríguez Borja | Arturo Carratalá Calvo

PROPUESTA DE INFORME DE LABORATORIO EN LA BIOQUÍMICA URINARIA AUTOMATIZADA
Figure 1. Laboratory report proposal for automated urinary biochemistry.
 
Difficulty in clinical laboratory reports interpretation frequently lies in the elevated number of parameters (clinical tests and calculated values) that are displayed. Reports for automated urinary biochemistry are a good example of this situation.

In order to make easier interpretations, in our lab we decided to divide urinary laboratory reports into three physiological parts based on the renal location where filtration, reabsorption or secretion from each analyte are mainly performed, achieving a complete functional evaluation.

BINUCLEATED LYNPHOCYTES CHARACTERISTIC OF POLYCLONAL B-CELL LYNPHOCYTOSIS

Written by Silvia Montolio Breva | Rafael Sánchez Parrilla | Isabel Fort Gallifa

LINFOCITOS BINUCLEADOS CARACTERÍSTICOS DE LINFOCITOSIS B POLICLONAL
Figure 1. Binucleated lymphocytes in peripherical blood smear (May-Grünwald-Giemsa) in a polyclonal b-cell lymphocytosis patient.

An image of an extension of peripheral blood smear, stained with May-Grünwald-Giemsa, is presented (figure 1). It is observed binucleated lymphocytes. These entities are constant and they are almost a exclusive feature of persistent polyclonal B lymphocytosis (LBPP). Morphologically, the lymphocytes are medium-large in size with a moderately condensed, bilobed nucleus, with a broad and slightly basophilic cytoplasm, as seen in the image. In addition, it is also common to observe the presence of lymphocytes with a central incisure nucleus, more or less deep that represents the different evolutionary stages prior to the binucleated lymphocyte (figure 2).

EARLY DETECTION OF SULPHADIAZINE CRYSTALS IN URINE

Written by Alejandro José Ravelo Marrero | Pablo Mediavilla Santillán | Olga Campos Noceda

DETECCIÓN PRECOZ DE CRISTALES DE SULFADIAZINA EN ORINA

A 49-year-old male HIV positive patient came to hospital for sudden impairment of his writing capacity of new onset without other associated symptoms. A cerebral nuclear magnetic resonance was performed, showing a space occupying lesion in the right temporoparietal space with cortical involvement, ring enhancement and associated perilesional edema. He began oral corticosteroid treatment and became asymptomatic.

CELL CANNIBALISM AND MITOSIS IN MALIGNANT PLEURAL FLUID

Written by Óscar Fuster Lluch | Mónica Piqueras Rodríguez | Rocío Andreu Escrivá

CANIBALISMO CELULAR Y MITOSIS EN LÍQUIDO PLEURAL MALIGNO
Figure 2. Cannibalism and cell in mitosis. In the figure, a cell mitosis can be seen in the upper central part, accompanied in the lower right part of the figure by multiple cells in which cannibalism can be observed. (Pleural fluid smear. Quick panoptic stain. 600x).

An image of a pleural fluid smear stained with quick panoptic is presented. The figure shows abundant atypical cells and cell cannibalism phenomenon that suggest a neoplastic origin (figure_1). The situation described was observed in many fields of pleural fluid smear, along with abundant atypical nest cells with mitosis phenomena (figure 2).
