RESUMO
INTRODUCTION: As little is known about the prognostic value of CT scan findings at onset in patients presenting with sarcoidosis, we aimed to identify factors independently associated with radiological remission of pulmonary involvement in systemic sarcoidosis on CT scan findings. METHODS: We conducted a retrospective descriptive and analytic study of patients with a biopsy proven systemic sarcoidosis. We compared patients on radiological remission (group 1) to those on stabilization or progression (group 2). Multivariate analysis of variables significantly associated with radiological remission in univariate analysis was performed using binary logistic regression. RESULTS: Out of 65 records of systemic sarcoidosis, 43 were analyzed. 18.6% where male and 81.6% female with a sex-ratio of 0.22 and a mean age at diagnosis of 47.2 ±13.6 years. We found atypical lesions in CT scan findings in 16 patients (37.2%). Comparative pulmonary CT scan findings at admission and at 12 months follow-up revealed 13 patients (30.2%) in remission (group1) and 30 patients in radiological stabilization or progression (group 2). On multivariate analysis, lymphopenia, calcifications, and typical CT scan findings at presentation were predictive factors of remission of pulmonary involvement in systemic sarcoidosis (aOR=27.57; 95%IC=2.67-284.63; p=0.005) (aOR= 37.2; 95%IC= 2.08-663.89; p= 0.014) (aOR=47.1; 95%IC= 1.79-1238.7; p=0.021) respectively. CONCLUSION: In patients with systemic sarcoidosis with no lymphopenia at onset or calcifications or typical CT scan findings at presentation, we suggest a close follow-up as well as an intensive treatment.
RESUMO
Hughes-Stovin syndrome is a rare disease characterized by thrombophlebitis associated with arterial or bronchial aneurysms. Even though it was described first in 1911, it is scarcely reported in the literature. Hughes-Stovin syndrome diagnosis is based on clinical manifestations as well as radiological findings. There are no validated criteria or specific laboratory findings to confirm the diagnosis. Computed tomography pulmonary angiography remains the gold standard for the diagnosis and follow-up of radiological findings, as they were recently described in a critical analysis of the largest cohort in the literature. The aim of this review is to draw attention to this rare but potentially fatal disease and to discuss its therapeutic options.
RESUMO
INTRODUCTION: Few experiences have been reported in simulation-based learning (SBL) in internal medicine. AIM: To assess the SBL impact in internal medicine learning on learners' perception, knowledge acquisition, and cognitive and communication skills evaluation. METHODS: A prospective observational study conducted in the Simulation Center at the Faculty of Medicine of Monastir between November 2018 and March 2019. High fidelity sessions were intended for lupus flare diagnosis and a standardized patient session for therapeutic education of patients on antivitamin K treatment. RESULTS: A total of 118 third-year undergraduate medical learners split into 9 groups attended 9 SBL sessions. Regarding learners' perception, gain in communication was felt among 117 learners (99.1%) and gain in confidence among 116 of them (98.3%). As for SBL impact on knowledge acquisition, the overall median pre and post-test scores were 5.76 / 10 (4.61-6.92) and 7.69 / 10 (6.92-9.23) respectively (p = 10-3). The median overall improvement score was 2.3(0.76-3.07). Assessing learners' skills made it possible to highlight certain learners' shortcomings which we focused on during debriefing. CONCLUSION: According to the current study, SBL was associated with a high level of learners' satisfaction and was effective in optimizing knowledge and communication in lupus flare diagnosis and antivitamin K management.
