ABSTRACT
INTRODUCTION AND IMPORTANCE: The tonsillar location of pleomorphic adenomas is rare in histological diagnosis. The elimination of other essentially lymphomatous diagnoses is essential. CASE PRESENTATION: We present a case of a 15-year-old child who consults for a feeling of pharyngeal discomfort and difficulty eating solid foods for 6 months. Clinical examination and radiology (MRI) showed the presence of a mass in the tonsillar region. A biopsy revealed a pleomorphic adenoma. The tumor was removed transorally with good progress. CLINICAL DISCUSSION: Pleomorphic adenoma of the tonsillar region is rare. Only histological examination can confirm this. Resection of the tumor must be complete in order to limit the risk of recurrence. CONCLUSION: The pleomorphic adenoma of the tonsillar region has a non-specific clinical presentation. MRI helps guide the diagnosis. Its treatment is surgical requiring complete excision.
ABSTRACT
Simulation-based medical education is becoming a cornerstone in health education. Simulators are commonly expensive and not available in developing countries. We propose a very low-cost simulator that any educator can realize. We describe here the steps to follow to develop this proposed simulator.
ABSTRACT
INTRODUCTION: Stroke is a public health problem worldwide. Community stroke knowledge is crucial to guide the prevention approach. We aimed to evaluate the level of stroke knowledge among the visitors to Emergency Centres (ECs) in the southern region of Tunisia concerning factors of risk, symptoms, and treatment of stroke. METHODS: A multicenter cross-sectional survey about stroke knowledge; conducted in five ECs for 10 days. All the visitors to these ECs were invited to participate in this survey. In each center, one investigator had to conduct the questionnaire. We used the stroke knowledge test (SKT). RESULTS: We enrolled 839 participants aged at 44 ± 7 years and with an M/F sex-ratio at 0.9. Relatives and mass media were the most reported sources of information about stroke. In 32.3% of cases, the participants had a university schooling level. The upper quartile had an SKT score of 55% or over (n = 247; 29.4%). The SKT score was significantly higher in young, female participants, in rural centers, with a university level of schooling and with no reported chronic diseases. Receiving information about stroke through the medium of television or via relatives was an independent predictor of a high SKT score compared with other knowledge sources. CONCLUSION: This study emphasises the urgent need for improving the population's knowledge about stroke in Tunisia. These findings may reflect the lack of government policies for education and training on stroke. A national educating program is necessary to implement to increase stroke knowledge.
ABSTRACT
INTRODUCTION: Tranexamic acid (TXA) is one of the debated therapies in the management of traumatic brain injury (TBI). We conducted this study to evaluate the benefits of TXA in TBI on the mortality and its safety in these patients. METHODS: This was a prospective randomized open-label trial including all patients, aged at 18 years or older, hospitalized in the emergency room during a 13-month period, for TBI. After the realization of the body CT scan, the patients were included if they had intracranial bleeding, and were then randomized according to their medical file number to receive or not the TXA. The eligibility criteria were based on the uncertainty principle, patients with significant extracranial bleeding were excluded since there was evidence that TXA improve their outcome. RESULTS: We enrolled 180 patients aged at 42 ± 20 years, with an 88% men-proportion. Subarachnoid haemorrhage was the most frequent lesion in the brain CT-scan (67.5%). After randomization, 96 patients were in the TXA group (53%). Demographic data, clinical, biological and radiological features were statistically comparable in the two groups of patients ('TXA' and 'noTXA'). The needs of transfusion or neurosurgery, the mortality rate, the in-hospital length of stay and the dependency at 28-post-traumatic day were similar in the two groups of patients. However, pulmonary embolism was statistically more frequent in 'TXA' group (11.5 versus 2.4%, p = 0.02). CONCLUSION: TXA is an interesting treatment in haemorrhagic shock. Its efficiency in head trauma is still debated and controversial. Its impact on the mortality and the needs of transfusion or surgery were not demonstrated in this study. Nevertheless, its safety worth to be studied in larger samples as we found a higher rate of pulmonary embolism in the treated group.
