Intracranial neoplasia is frequently encountered in dogs. After a presumptive diagnosis of intracranial neoplasia is established based on history, clinical signs and advanced imaging characteristics, the decision to treat and which treatment to choose must be considered. The objective of this study is to report survival times (ST) for dogs with intracranial meningiomas and gliomas treated with surgical resection alone (SRA), to identify potential prognostic factors affecting survival, and to compare the results with the available literature. Medical records of 29 dogs with histopathologic confirmation of intracranial meningiomas and gliomas treated with SRA were retrospectively reviewed. For each dog, signalment, clinical signs, imaging findings, type of surgery, treatment, histological evaluation, and ST were obtained. Twenty-nine dogs with a histological diagnosis who survived >7 days after surgery were included. There were 15 (52%) meningiomas and 14 (48%) gliomas. All tumors had a rostrotentorial location. At the time of the statistical analysis, only two dogs were alive. Median ST for meningiomas was 422 days (mean, 731 days; range, 10-2735 days). Median ST for gliomas was 66 days (mean, 117 days; range, 10-730 days). KaplanMeier analysis indicated that ST was significantly longer for meningiomas than for gliomas (P<0.05). A negative correlation between the presence of a midline shift and ST (P=0.037) and ventricular compression and ST (P=0.038) was observed for meningiomas. For gliomas, there were no significant associations between ST and any of the variables evaluated. In conclusion, the results of this study suggest that, for dogs that survived >7 days postoperatively, SRA might be an appropriate treatment, particularly for meningiomas, when radiation therapy is not readily available. Also, the presence of midline shift and ventricular compression might be negative prognostic factors for dogs with meningiomas.
Objective:Using validated psychological assessment instruments, this study examined the psychological distress associated with potential language barriers experienced by over 135 000 Puerto Rican residents who either temporarily or permanently migrated to the continental United States with the landfall of Hurricane Maria in 2017.Methods:Participants were Puerto Rican residents (n = 107) who remained in Puerto Rico (control) or left the island for at least 3 months because of Hurricane Maria (migrants). Participants completed an online survey in their preferred language (Spanish or English), which assessed self-reported English language proficiency, Kessler Psychological Distress Scale (K6), Posttraumatic Stress Disorder Checklist for DSM 5, Patient Health Questionnaire 9-item depression scale, and the Generalized Anxiety Disorder 7-item scale. It was hypothesized that migrants with lower self-reported English proficiency would have comparatively higher indices of post-disaster distress than those with a higher proficiency.Results:Dividing the migrant group by preferred language for questionnaire completion, the Fisher’s exact test showed significant differences in prevalence of severe mental distress, as defined by K6 scores above 13, between the Spanish-preferring migrants (30.4%), English-preferring migrants (0%), and controls (9.6%).Conclusion:Our results support a possible correlation between decreased language proficiency in post-disaster migrants and a higher risk factor for severe mental distress.
OBJECTIVE To determine the prevalence of presumed postictal changes (PC) on brain MRI in epileptic dogs, describe their distribution, and recognize possible correlations with different epilepsy features. ANIMALS 540 client-owned dogs with epilepsy and a complete medical record that underwent brain MRI at 4 veterinary referral hospitals between 2016 and 2019. PROCEDURES Data were collected regarding signalment, seizure type, seizure severity, time between last seizure and MRI, and etiological classification of epilepsy. Postictal changes were considered when solitary or multiple intraparenchymal hyperintense lesions were observed on T2-weighted and fluid-attenuated inversion recovery images and were hypointense or isointense on T1-weighted sequences, which were not confined to a vascular territory and showed no to mild mass effect and no to mild contrast enhancement. RESULTS Sixty-seven dogs (12.4%) showed MRI features consistent with PC. The most common brain sites affected were the piriform lobe, hippocampus, temporal neocortex, and cingulate gyrus. Dogs having suffered cluster seizures or status epilepticus were associated with a higher probability of occurrence of PC, compared to dogs with self-limiting seizures (OR 2.39; 95% confidence interval, 1.33 to 4.30). Suspected PC were detected both in dogs with idiopathic epilepsy and in those with structural epilepsy. Dogs with unknown-origin epilepsy were more likely to have presumed PC than were dogs with structural (OR 0.15; 95% confidence interval, 0.06 to 0.33) or idiopathic epilepsy (OR 0.42; 95% confidence interval, 0.20 to 0.87). Time between last seizure and MRI was significantly shorter in dogs with PC. CLINICAL RELEVANCE MRI lesions consistent with PC were common in epileptic dogs, and the brain distribution of these lesions varied. Occurrence of cluster seizures or status epilepticus, diagnosis of unknown origin epilepsy, and lower time from last seizure to MRI are predictors of suspected PC.
This report describes the case of a 45-year-old woman with a history of Behçet’s disease and complex regional pain syndrome of her legs who presented with severe pain and swelling in her left lower extremity. The patient was initially diagnosed with exacerbation of complex regional pain syndrome, which fit the symptom complex of hyperalgesia, oedema and skin temperature changes. However, after unsuccessful attempts at significant pain relief during admission, CT angiography demonstrated occlusion of the left common and external iliac arteries, a limb-threatening emergency. This case describes an example of anchoring bias, a type of cognitive bias in which there is a tendency to rely too heavily on an initial piece of information, the ‘anchor’, when making decisions. This report emphasises that clinicians should be aware of biases when making decisions and avoid anchoring bias by asking themselves if their diagnosis is influenced by any leading pieces of information.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
