LÍNEA EDITORIAL DE NUESTRA REVISTA

LÍNEA EDITORIAL DE NUESTRA REVISTA
Hace exactamente 4 años que nuestra revista nació apelando a la curiosidad, siendo esta un pilar necesario de la investigación y como denominador común de los grandes científicos que han existido y existen en la historia de la humanidad. Una revista que empezaba publicando "imágenes curiosas".

Muchas veces creemos que la ciencia es matemática, estadística, etc., pero realmente son algunas de las herramientas del científico para comprobar sus hipótesis.

INFRARED SPECTROSCOPY IN THE IDENTIFICATION OF THE CALCIUM CARBONATE LITHIASIS

Written by María Santamaría González | Paula Sienes Bailo | José Luis Bancalero Flores

ESPECTROSCOPÍA INFRARROJA EN LA IDENTIFICACIÓN DE LAS LITIASIS DE CARBONATO CÁLCICO
Figure 1. Multiple kidney stones composed of calcite from a 64-year-old man subjected to lithotripsy. The structure is described as granuloporous, concentric in the nucleus and the trigonal system crystallization. Its composition is 90% calcite, 10% calcium oxalate monohydrate. In the lower, the infrared spectrum of the stone is shown, and at right, the effervescence when it reacts with 0.2M HCl, generating bubbles of CO2 can be observed.

FERN LEAVES IN A URINARY SEDIMENT. CLINICAL RELEVANCE OR ARTEFACT?

Written by Rita Losa Rodríguez | Gabriel Rodríguez Pérez | Guadalupe Ruiz Martín

HOJAS DE HELECHO EN UN SEDIMENTO URINARIO.  ¿RELEVANCIA CLÍNICA O ARTEFACTO?
Figure. Ammonium phosphate crystals "fern leaf" in urine. A) Optical microscopy, x400 increases. B) Polaryzed light filter, x200 increases.

We present the case of a young female patient, with a history of urinary tract infection with positive cultures, whose urine was sent from Primary Care for analysis. Its physical characteristics included dark brown urine and intense smell. Given the altered parameters of the test strip (pH 9, Proteins +, Nitrites + and Leukocytes +), we proceeded to make the sediment analysis. In this one, the presence of abundant crystalline forms of unusual morphology was highlighted, as shown in figure.

Pleural effusion and rheumatoid arthritis: Diagnostic value of the microscopic examination of pleural fluid

Written by Laura Sánchez Torres | Rafael Zambrana Moral | María Monsalud Arrebola Ramírez

DERRAME PLEURAL Y ARTRITIS REUMATOIDE:    VALOR DIAGNÓSTICO DEL EXAMEN MICROSCÓPICO DEL LÍQUIDO PLEURAL
Figure 1.  Cholesterol crystals in pleural fluid in light field at 400 increases to 1/10 dilution.

The image belongs to the pleural fluid (PF) of a 67-year-old man with a history of erosive rheumatoid arthritis (RA), who presented to the emergency department with progressive dyspnea. The chest radiograph performed at admission showed bilateral pleural effusion (PE), so he is admitted for complete his differential study between de novo heart failure or secondary to RA. The patient underwent four days of depletion treatment, after which control radiography showed complete resolution of the right PE and persistence of the left PE. This led to the performance of diagnostic thoracoscopy and evacuation of the persistent PE.

DIAGNOSIS OF CHROMOSOME 4 LONG ARM MICRODELETION SYNDROME BY ARRAY-CGH

Written by Jorge Paco Ferreira | Ramón Giné Benaiges | Alfredo Santana Rodríguez

DIAGNÓSTICO DEL SÍNDROME DE MICRODELECIÓN DEL BRAZO LARGO DEL CROMOSOMA 4 MEDIANTE ARRAY-CG

We report a clinical case of a pregnant woman, through IVF, of 40 years old referred to the Clinical Genetics Unit of the Clinical Analysis and Clinical Biochemistry Service of Maternal and Child Insular University Hospital Complex of Las Palmas de Gran Canaria, due to the pregnant woman´s advanced age.

DIAGNOSIS OF CYSTINURIA BY DIRECT VISION IN THE URINARY SEDIMENT

Written by Alexia Rubio Peral | Ana Velasco Romero | M. Francisca García Codesal

DIAGNÓSTICO DE CISTINURIA POR VISIÓN DIRECTA EN EL SEDIMENTO URINARIO
Figure 1. Images taken in ordinary light (oc x10, obj x40) in which cystine crystals are observed at different degrees of maclation, more intense in the below image.

Cystinuria is a hyperaminoaciduria due to a defective transport of cystine and dibasic aminoacids (ornithine, arginine and lysine) in the apical membrane of the intestinal epithelium and the renal proximal tubule, which leads to an excess removal of cystine through urine. It is transmitted with an autosomal recessive inheritance pattern, with an average prevalence in neonates of 1/7000.
