ABSTRACT
Cutaneous tuberculosis is a rare extrapulmonary pre-sentation of tuberculosis, caused by mycobacterial species of the Mycobacterium tuberculosis complex. We describe a case of cutaneous tuberculosis in a 57-year-old technician from the microbiology laboratory in our hospital. She accidentally experienced a needlestick injury with a hollow needle while at work. Skin lesion developed shortly after on the punctured finger. A biopsy was performed, revealing necrotizing (caseating) granulomatous inflammation. Pharmacological treatment was initiated with four standard drugs: isoniazid, rifampicin, pyrazinamide, and ethambutol hydrochloride. Improvement was observed, but the initial treatment had to be suspended due to intolerance to some of the drugs and changed to a treatment with isoniazid, rifampicin, and levofloxacin. The long duration of the treatment may increase the risk of toxic effects, making it necessary to discard the drug causing these effects and change the treatment regimen.

Background and Aims: The benefits of Mediterranean Diet (MeDiet) in prevention of cardiovascular diseases (CVD) in general and ischemic stroke (IS) have been extensively studied and reported. We hypothesize that the consumption of nutrients typical of MeDiet would also reduce the rate of silent brain infarcts (SBI) among AF patients. Methods and Results: Patients with a history of AF who scored 0 to 1 in the CHADS2 score, ⩾50 years and with absence of neurological symptoms were selected from Seville urban area using the Andalusian electronic healthcare database. A 3T brain MRI was performed to all participants. Demographic and clinical data and food-frequency questionnaire (FFQ) were collected. Of the 443 scanned patients, 66 presented SBI. Of them 52 accepted to be scheduled for a clinical visit and were included in the diet sub study and 41 controls were matched per age and sex. There were no statistically significant differences in baseline characteristics. After logistic regression analysis, we found that a higher consumption of fiber from fruit was independently associated with a lower risk of SBI, while a higher consumption of high glycemic load (GL) foods was associated with a higher risk of SBI in a population with AF. Conclusion: Our findings support that MeDiet could be suggested as a prevention strategy for SBI in patients with AF.
ABSTRACT
La tuberculosis cutánea es una presentación extrapulmonar poco común de la tuberculosis, producida por la infección por especies de micobacterias del complejo Mycobacterium tuberculosis. Se presenta un caso de tuberculosis cutánea en una trabajadora de 57 años, Técnico Especialista de Laboratorio en el Servicio de Microbiología, tras sufrir accidente de trabajo por pinchazo accidental con aguja hueca. Al poco tiempo desarrolló lesión cutánea en el dedo que fue biopsiada e informada de inflamación granulomatosa necrotizante (caseificante). Se inició tratamiento con cuatro fármacos: isoniazida, rifampicina, pirazinamida y etambutol hidrocloruro, con mejoría cutánea y fue suspendido por mala tolerancia, cambiando el tratamiento a isoniazida, rifampicina y levofloxacino. Debido a la larga duración del tratamiento, existe riesgo de aparición de algún efecto tóxico que obligue a prescindir definitivamente del fármaco causante y cambiar la pauta.(AU)

Previous studies have shown the potential of microRNAs (miRNA) in the pathological process of stroke and functional recovery. Bone marrow mononuclear cell (BM-MNC) transplantation improves recovery in experimental models of ischemic stroke that might be related with miRNA modifications. However, its effect on circulating miRNA has not been described in patients with stroke. We aimed to evaluate the circulating levels of miRNAs after autologous BM-MNC transplantation in patients with stroke. We investigate the pattern of miRNA-133b and miRNA-34a expression in patients with ischemic stroke included in a multicenter randomized controlled phase IIb trial (http://www.clinicaltrials.gov; unique identifier: NCT02178657). Patients were randomized to 2 different doses of autologous intra-arterial BM-MNC injection (2×106/kg or 5×106/kg) or control group within the first 7 days after stroke onset. We evaluate plasma concentration of miRNA-113b and miRNA-34a at inclusion and 4, 7, and 90 days after treatment. Thirteen cases (8 with 2×106/kg BM-MNC dose and 5 with 5×106/kg dose) and 11 controls (BM-MNC non-treated) were consecutively included. Mean age was 64.1±12.3 with a mean National Institutes of Health Stroke Scale score at inclusion of 14.5. Basal levels of miRNA were similar in both groups. miR-34a-5p and miR-133b showed different expression patterns. There was a significant dose-dependent increase of miRNA-34a levels 4 days after BM-MNC injection (fold change 3.7, p<0.001), whereas miRNA-133b showed a significant increase in the low-dose BM-MNC group at 90 days. Intra-arterial BM-MNC transplantation in patients with ischemic stroke seems to modulate early circulating miRNA-34a levels, which have been related to precursor cell migration in stroke and smaller infarct volumes.
