[Iodinated contrast-induced encephalopathy: a pathology that must be borne in mind when carrying out endovascular examinations]. / Encefalopatia por contraste iodado: una patologia que se debe tener en cuenta en el desarrollo de las exploraciones endovasculares.

INTRODUCTION: In recent years there has been an increase in the number of endovascular examinations in the study of both cardiovascular and cerebrovascular diseases. One very infrequent complication is neurotoxicity due to contrast, and it must be suspected within the context of a neurological deficit following such examinations in order to be able to diagnose it. CASE REPORT: A 61-year-old male who presented an epileptic attack and later deficit in the left hemisphere following diagnostic arteriography. After ruling out the possibility of an urgent vascular pathology, he was submitted to a magnetic resonance brain scan with the suspicion of this condition. The clinical signs and symptoms were limited to 72 hours with cortisone therapy. CONCLUSIONS: Contrast-induced encephalopathy covers a wide range of clinical features which, in the vast majority of cases, are self-limiting to 24-72 hours, and within the context of neuronal damage following contrast infusion. Its prognosis is excellent, and diagnostic suspicion is crucial in its treatment.

TITLE: Encefalopatia por contraste iodado: una patologia que se debe tener en cuenta en el desarrollo de las exploraciones endovasculares.Introduccion. En los ultimos años ha aumentado el numero de exploraciones endovasculares en el estudio de la patologia tanto cardiovascular como cerebrovascular. Una de las complicaciones poco frecuentes es la neurotoxicidad por contraste y su sospecha resulta imprescindible en el contexto de un deficit neurologico tras dichas exploraciones para llegar a su diagnostico. Caso clinico. Varon de 61 años que tras una arteriografia diagnostica en el estudio de una hemorragia subaracnoidea presento una crisis epileptica y posteriormente deficit hemisferico izquierdo. Tras descartar una patologia vascular urgente, se realizo una resonancia magnetica cerebral con sospecha de encefalopatia poscontraste. La clinica se limito en 72 horas con corticoterapia. Conclusiones. La encefalopatia por contraste abarca un amplio espectro clinico, en la inmensa mayoria de los casos autolimitado en 24-72 horas, y en el contexto del daño neuronal tras la infusion de contraste. Su pronostico es excelente y la sospecha diagnostica es vital en el tratamiento.

[Recurrent aseptic meningitis secondary to taking ibuprofen and ketorolac]. / Meningitis recurrente aséptica secundaria a toma de ibuprofeno y ketorolaco.

INTRODUCTION: Aseptic meningitis is a process that is characterised by an inflammatory reaction of the meninges that is not due to any infectious agent. Its aetiology is varied and is most frequently caused by rheumatologic and/or autoimmune processes, chemical or medication-induced meningitis, the most notable drugs involved being antibiotics and non-steroidal anti-inflammatory drugs (NSAI). CASE REPORT: We report the case of a 70-year-old male, with no relevant history, who was admitted to hospital five times over a period of 16 months because of acute meningitis with polymorphonuclear pleocytosis, high protein levels in cerebrospinal fluid and normal glucose in cerebrospinal fluid. No evidence of an infectious causation, chemical meningitis, carcinomatosis or autoimmune disease was found and the patient was diagnosed with recurrent aseptic meningitis. It was found that the patient had taken ibuprofen or ketorolac on several occasions, a few hours before the appearance of symptoms. These episodes were quickly resolved after withdrawal of this medication. CONCLUSIONS: A number of NSAI have been reported as inducers of aseptic meningitis, one of the most notable being ibuprofen. We report the case of a patient who, as a consequence of taking ibuprofen and ketorolac, presented episodes of recurrent aseptic meningitis. To our knowledge this side effect of ketorolac has not been reported before. Its clinical features are impossible to differentiate from those of infectious meningitis. Diagnosis is reached by exclusion and a careful pharmacological study, including over-the-counter drugs like some of the NSAI, must be performed in patients with this condition, since it is a problem that can easily be solved by withdrawing the drug that causes it.

[Aphasia and parietal syndrome as the presenting symptoms of a demyelinating disease with pseudotumoral lesions]. / Afasia y síndrome parietal como forma de presentación de una enfermedad desmielinizante con lesión pseudotumoral.

INTRODUCTION: Multiple sclerosis (MS) often presents with sensory symptoms, which are usually due to spinothalamic or spinal cord disorders; parietal syndrome is, however, very rare as the initial symptom. Likewise, aphasia is also an infrequent symptom of MS; in the few cases that have been reported, it is usually linked to the existence of important pseudotumoral lesions. CASE REPORT: We describe the case of a 31-year-old female with a 48-hour history of a progressive clinical picture consisting in nominal aphasia and a sensory parietal syndrome. Magnetic resonance imaging showed a lesion 3.6 cm in diameter that was hyperintense in T2 with perilesional edema and minimal gadolinium uptake, along with other images that revealed increased signal intensity in the periventricular subcortical white matter on the right-hand side and in the left-hand frontal subcortical region. A spectroscopic analysis of the largest lesion revealed that this lesion showed evidence of inflammation, with cell destruction and replacement, although it was not possible to distinguish between a demyelinating disease and a high grade glioma. Hence, a brain biopsy was required in order to reach the final diagnosis of demyelinating pseudotumoral lesion. CONCLUSIONS: Giant pseudotumoral plaques are a rare form of presenting symptom in MS; use of the clinical features, simple images and spectroscopy is not a very reliable means of reaching a differential diagnosis with a tumour and this often makes it necessary to conduct a biopsy study of the lesion.

[Expert opinion on the basic surgical technique for laparoscopic ventral hernia repair]. / Técnica quirúrgica básica consensuada para el tratamiento por vía laparoscópica de las hernias ventrales.

Laparoscopic ventral hernia repair is currently the subject of intense debate, even though it provides a series of advantages over open surgery and is feasible and safe. Various studies have shown this technique to be as effective as open repair with a lower recurrence rate. Despite the excellent results of laparoscopic repair of ventral hernias, there are numerous controversies associated with this procedure. These controversies concern the indications and contraindications of the procedure, and technical aspects such as how to create the pneumoperitoneum, perform adhesiolysis, manage the hernia sac, and insert and fix the mesh to the anterior abdominal wall. Also controversial are outcome, complications related to postoperative seroma, and which type and size of mesh should be used. The present article aims primarily to address many of these issues, based on the experience of distinct surgeons with expertise in this approach, in order to provide data to establish a consensus on how laparoscopic ventral hernia repair should be performed.
