RESUMEN
Foot-and-mouth disease (FMD) is a major infectious disease in livestock. The common clinical signs in cattle include epidermal vesicles that are majorly distributed around oronasal cavity, feet and teats. The aim of this report is to document an uncommon clinical form of the disease which comprises the occurrence of classic vesicular lesion in a rarely observed location of the horn vegetative tissue. During Iran's outbreak of FMD in 2013, field investigation, clinical examination and sampling from the affected herds in Qom province were performed. Specimens of mouth epithelium and horn vegetative tissue were collected for virology and histopathologic study. All the samples collected from horns were positive for foot-and-mouth disease virus (FMDV) in both enzyme linked immunosorbent assay (ELISA) and polymerase chain reaction (PCR) tests, and the strain of the virus was identified as A05. Surprisingly, all the animals with horn lesion came from beef herds, were less than 12 months old and had more severe signs of the systemic disease. Since the same strain of virus did not cause similar lesions in surrounding dairy cows, it was concluded that occurrence of horn lesions may be more associated with host factors rather than virus strain.
RESUMEN
Introduction. Strokes and stroke-mimics have been extensively studied in the emergency department setting. Although in-hospital strokes are less studied in comparison to strokes in the emergency department, they are a source of significant direct and indirect costs. Differentiating in-hospital strokes from stroke-mimics is important. Thus, our study aimed to identify variables that can differentiate in-hospital strokes from stroke-mimics. Methods. We present here a retrospective analysis of 93 patients over a one-year period (2009 to 2010), who were evaluated for a concern of in-hospital strokes. Results. About two-thirds (57) of these patients were determined to have a stroke, and the remaining (36) were stroke-mimics. Patients with in-hospital strokes were more likely to be obese (p = 0.03), have been admitted to the cardiology service (p = 0.01), have atrial fibrillation (p = 0.03), have a weak hand or hemiparesis (p = 0.03), and have a prior history of stroke (p = 0.05), whereas, when the consults were called for "altered mental status" but no other deficits (p < 0.0001), it is likely a stroke-mimic. Conclusion. This study demonstrates that in-hospital strokes are a common occurrence, and knowing the variables can aid in their timely diagnosis and treatment.
RESUMEN
Facial hemangioma can be isolated lesions or associated with a wide variety of systemic findings. We report a 9-month-old girl who shows an extensive facial hemangioma, intracranial and extracranial vascular malformations, a Dandy-Walker malformation and congenital cardiac malformations. This patient serves as an ample reason why children with similar cutaneous lesions should be carefully evaluated for other associated defects.
