[Prognostic factors in idiopathic pulmonary fibrosis in a tunisian cohort]. / Facteurs pronostiques au cours de la fibrose pulmonaire idiopathique : étude d'une cohorte tunisienne.

We present data on prognostic factors in a Tunisian cohort of people with Idiopathic pulmonary fibrosis. INTRODUCTION: Idiopathic pulmonary fibrosis (IPF) has a poor prognosis, with a median survival in patients with the condition of only 3 to 5 years. Previous studies have identified a number of prognostic factors in this chronic pulmonary disease. METHODS: We conducted a retrospective study, including patients with idiopathic pulmonary fibrosis (IPF) who were diagnosed at the Pneumology Department of the University Hospital Fattouma-Bourguiba, Monastir, between 1991 and 2014. The aim of this study was to compare clinical, radiological, pulmonary functional predictors of survival in IPF in a Tunisian cohort with those of previous studies. RESULTS: This study included 126 patients. Their mean age was 66 years, with a male predominance (68.3%). Respiratory function tests revealed a restrictive ventilatory deficit in 72.6% of cases. The median survival of our study population was 22.5 months [6.7-49.5]. In univariate analysis, factors associated with a poor prognosis were: lower baseline values of TLC, FCV and DLco, level of dyspnea assessed by mMRC scale, hypoxemia at diagnosis, the degree of desaturation during exercise, a higher annual decline of FVC and DLco, acute respiratory distress and also the GAP score. In multivariate analysis, independent prognostic factors were: baseline DLco, level of dyspnea, desaturation at exertion and the annual decline of the DLco. CONCLUSION: Lower baseline DLco, the level of dyspnea, desaturation on exercise, and annual decline in DLco are all associated with a poor prognosis in IPF.

Risk assessment for foot ulcers among Tunisian subjects with diabetes: a cross sectional outpatient study.

BACKGROUND: Diabetic foot is an underestimated and redoubtable diabetes complication. The aims of our study were to assess diabetic foot ulcer risk factors according to International Working Group on the Diabetic Foot (IWGDF) classification, stratify patients into risk categories and identify factors associated with higher-risk grade. METHODS: Cross-sectional setting over a period of 07 months, patients were randomly selected from the diabetic outpatients attending our unit of diabetology. Questionnaire and clinical examination were made by the same physician. Patients free of active foot ulcer were included. RESULTS: Among 230 patients evaluated, 10 had an active foot ulcer and were excluded. Five patients (2.27%) had a history of foot ulcer and 3(1.36%) had a lower-limb amputation. Sensory neuropathy, as measured by the 5.07(10 g) Semmes-Weinstein monofilament testing, was present in 23.63% of patients, whereas 36.82% had a peripheral arterial disease based on clinical findings, and 43.63% had foot deformities. According to the IWGDF classification, Group 0: 72.72%, Group 1: 5.9%, Group 2: 17.73% and Group 3: 3.63%. After univariate analysis, patients in higher-risk groups were significantly more often female, had higher age and BMI, longer diabetes duration, elevated waist circumference, low school level, retinopathy and hyperkeratosis. Multivariate logistic regression analysis identified 3 significant independent factors associated with high-risk groups: retinopathy (OR = 2.529, CI95 [1.131-5.655], p = 0.024), hyperkeratosis (OR = 2.658, CI95 [1.222-5.783], p = 0.014) and school level (OR = 0.489, CI95 [0.253-9.44], p = 0.033). CONCLUSIONS: Risk factors for foot ulceration were rather common in outpatients with diabetes. The screening of patients at risk for foot ulceration should start early, integrated with sustainable patient education.

[Contribution of high fidelity simulation to training in respiratory medicine]. / Apport de l'apprentissage par la simulation dans l'enseignement de la pneumologie.

INTRODUCTION: Simulation maintains patient safety by limiting the risk of errors. In the medical field, simulation is a method of learning that is developing more and more in the acute specialties but it is still not widespread in the field of respiratory medicine. OBJECTIVE: To evaluate the efficacy of high fidelity simulation as a teaching tool in respiratory medicine. METHODS AND POPULATION STUDIED: This was a prospective and descriptive study including students who had high fidelity simulation training sessions during their traineeship in respiratory medicine. Simulation learning took the form of four teaching sessions. The included students were assessed at the beginning and end of each session by a pre-test and post-test. Student satisfaction was assessed at the end of each session. RESULTS: Comparing the average student score before and after the simulation session showed an improvement in post-test scores. This improvement was statistically significant for all four scenarios. The majority of students, 60% (N=13), were satisfied with the progress of their internship in the Respiratory Department. CONCLUSION: High fidelity simulation is a teaching method that allows the acquisition and/or optimization of several skills. Nevertheless, this method remains undeveloped in respiratory medicine.
