[Neurodevelopment and phenocopies of attention deficit hyperactivity disorder: differential diagnosis]. / Neurodesarrollo y fenocopias del trastorno por deficit de atencion/hiperactividad: diagnostico diferencial.

INTRODUCTION: Attention deficit hyperactivity disorder (ADHD) is one of the most prevalent neurodevelopmental disorders. Other neurodevelopmental disorders may appear as a comorbidity or mimicking ADHD itself. DEVELOPMENT: This study reviews the high prevalence of other neurodevelopmental disorders (specific learning difficulties, communication disorders, etc.) in patients with ADHD. Moreover, the possible differential diagnoses include the same neurodevelopmental disorders that can occur as a comorbidity. Based on the literature, the study evaluates the role of clinical evaluation and neuropsychology in distinguishing between comorbidity and mimicry. CONCLUSIONS: The clinical evaluation could be insufficient for the comorbid diagnosis of neurodevelopmental disorders. In these cases, a neuropsychological evaluation is generally required, since it can also offer alternative diagnostic hypotheses about the symptoms observed and may therefore be a valuable aid for the differential diagnosis.

TITLE: Neurodesarrollo y fenocopias del trastorno por deficit de atencion/hiperactividad: diagnostico diferencial.Introduccion. El trastorno por deficit de atencion/hiperactividad (TDAH) es uno de los trastornos del neurodesarrollo mas prevalentes. Otros trastornos del neurodesarrollo pueden aparecer de forma comorbida o mimetizar el propio TDAH. Desarrollo. Se revisa la elevada prevalencia de otros trastornos del neurodesarrollo (trastornos especificos del aprendizaje, trastornos de la comunicacion...) en los pacientes con TDAH. Por otro lado, entre los posibles diagnosticos diferenciales se situan los mismos trastornos del neurodesarrollo que pueden aparecer de forma comorbida. Se valorara, de acuerdo a la bibliografia, el papel de la valoracion clinica y la neuropsicologia en la distincion entre comorbilidad y mimetismo. Conclusiones. La valoracion clinica podria ser insuficiente para el diagnostico comorbido de los trastornos del neurodesarrollo. En estos casos, la valoracion neuropsicologica es generalmente necesaria; esta puede igualmente ofrecer hipotesis diagnosticas alternativas de la sintomatologia observada y, por tanto, ser util para el diagnostico diferencial.

[Intestinal tuberculosis. A diagnostic challenge]. / Tuberculosis intestinal. Un reto diagnóstico.

Tuberculosis (TB) is a common disease in Spain, whose incidence has increased due to AIDS, immunotherapy and immigration. Intestinal disease is rare and can be difficult to diagnose because its symptoms and laboratory results are nonspecific. In addition, endoscopic lesions resemble those of other diseases such as Crohns disease (CD). Differentiating between intestinal TB and CD is very important since steroid treatment con be life saving in CD and lethal in intestinal TB. Colonoscopy plays an important role in establishing a suspected diagnosis. The endoscopic findings most characteristic of intestinal TB are circular ulcers, small diverticula (3-5 mm), and sessile firm polyps. The suspected diagnosis must be confirmed by the presence of caseating granulomas and/or acid fast bacilli. Polymerase chain reaction is currently recommended for assessing the presence of tubercle bacilli in tissue specimens obtained by endoscopic biopsy. We report a case of intestinal TB in a female renal transplant recipient that demonstrates the difficulty of making this diagnosis.

[Gastroenteritis eosinophilic presenting as colitis with acute abdomen]. / Presentación de gastroenteritis eosinofílica como brote de colitis con abdomen agudo.

Eosinophilic gastroenteritis is rare. Fewer than 30 cases have been published in the Spanish literature, although Kaijser first described this entity in 1937. Its etiology is still unknown and it has frequently been reported to involve the stomach and small bowel, with characteristic eosinophilic infiltration of the bowel wall. The colon has rarely been reported as a site of this condition, which manifests as acute abdominal pain due to intestinal obstruction. We report the case of a 38-year-old woman who presented eosinophilic gastroenteritis. Onset was acute colitis causing acute abdomen. The patient received conservative treatment and responded well to steroids. To our knowledge, such a case has not previously been reported.

[Cerebrovascular accidents and atrial fibrillation in the elderly patient]. / Accidente cerebrovascular y fibrilación auricular en el paciente anciano.

BACKGROUND: Cerebrovascular disease is the third cause of death in much of the occidental countries. Nowadays atrial fibrillation (AF) is well recognized as an independent and important risk factor for stroke in elderly people. Our aim is to know the frequency of AF in the patients who were admitted to a hospital for an ischemic stroke, the clinical risk factors associated to brain embolism and the prevention of cardiogenic brain embolism. METHODS: 164 patients older than 65 years were admitted to the hospital during 5 months, those who were suspected of stroke were studied prospectively. Only the patients who had a cerebral infarction demonstrated by computed tomography of brain with a neurological alteration of at least 3 days were included in the study. RESULTS: Fifty eight patients (27 men) met the ischemic stroke criteria. 22 of them had AF (9 men). Three of them had no other clinical risk factors associated and 19 had: hypertension in 10 cases, 8 had previous stroke and 1 had a episode of congestive heart failure 3 months before being admitted in the hospital. At the moment of admission only 4 patients were treated with aspirin and none with warfarin. CONCLUSIONS: a) 38% of elderly patients with stroke have AF. b) The association with other clinical factors that increase the risk of brain embolism is high (86%). c) The percentage of patients having a preventing treatment for cardiogenic embolism is very low.
