Future town planners should possess technical knowledge as users of geographical information systems (GIS) as well as certain skills in designing spatial databases and in spatial analysis. They also should understand GIS not only as a tool to be used in their work but also as part of an approach to organize urban planning and management. A Tunisian institute for urban-planning education has developed an approach to GIS education in which students progress through six levels over a sixyear training period. The progression corresponds to the sequence of activities performed by urban planners and highlights the roles of GIS in each activity. At the highest levels, GIS is considered not only as an efficient tool for spatial analysis but also as a way to define and assess urban policies. [ABSTRACT FROM AUTHOR]

Introduction: Sarcoidosis is a systemic granulomatosis that can be associated with large-scale physical and mental disability, affecting the health related quality-of-life (HRQoL) of patients., Aim: To evaluate the HRQoL of tunisian patients with sarcoidosis and to identify the factors that influence it., Methods: We conducted an analytical, cross-sectional study collecting 31 patients with sarcoidosis according to the ATS/ERS/WASOG criteria. The evaluation of the HRQoL was assessed by two questionnaires in tunisian dialect. The generic score was the Medical Outcome Study 36-Short Form Health Survey (SF-36).The specific score used was the Sarcoidosis Health Questionnaire (SHQ)., Results: The HRQoL of our 31 patients was more affected in the three domains of the SHQ compared to the SF-36, which is in favor of the better sensitivity of the SHQ to detect the influence of the extent of sarcoidosis on the HRQoL. Factors associated with more impaired HRQoLwere: age at disease onset, age at interview, comorbidities, altered spirometry results, ocular involvement, chronic cholestasis, splenic nodules, arthralgia, organ count ≥3, lymphopenia and cholestasis at the time of the interview. Taking an immunosuppressant agent, particularly Methotrexate, was associated with HRQoL improvement. The number of relapses was the most correlated factor with an altered HRQoL, and this in several domains., Conclusion: For an effective management of patients with sarcoidosis, a bio-psycho-social approach is now necessary in order to assess the real and global impact of the disease and to improve the HRQoL of patients. Disease-specific scores seem more reliable in achieving these goals.

IgA vasculitis nephritis affects the prognosis of this disease in adult patients. This study aimed to examine the clinical characteristics of this renal involvement in adults and to identify factors influencing renal prognosis. We conducted a retrospective monocentric study of patients with histologically confirmed IgA vasculitis nephritis (rheumatoid purpura) (EULAR classification criteria) with renal involvement classified according to Pillebout classification. We analyzed renal survival and identified the factors influencing renal prognosis. Twenty-five patients were included (sex ratio M/F = 2.57), their average age at diagnosis of rheumatoid purpura was 35,76 years. Purpura was diagnosed in 100% of cases, with articular involvement in 28% of cases. Renal failure was identified in 44% of cases. The most common histological classification was IgA vasculitis nephritis (class II). Clinical remission was observed in 44% of cases and an evolution toward chronic renal failure (end-stage renal disease) in 36% of cases. Renal survival at 195 months was 57%. The identified prognostic factors were digestive involvement (p = 0.022), early renal failure (p = 0.0004), glomerular classification (P=0,001) and the severity of the histological lesions, renin-angiotensin system blocker treatment (p = 0.01) and plasma exchanges (p = 0.03). Our study shows that renal involvement during IgA vasculites can be relatively severe with poor renal prognosis. The identification of clinical and histological prognostic factors may be useful as guidance for the development of prospective therapeutic studies., Competing Interests: Les auteurs ne déclarent aucun conflit d’intérêts.

Hemophagocyticlymphohistocytosis (HLH) is a proliferation of histiocytes with importanthemophagocytosisoccurring in different organs such as the spleen and the bone marrow. HLH is now increasingly diagnosed in the context of infections, malignancies and connective tissue diseases. Although brucellosis is an endemic infection in Tunisia, its association with HLH is a very rare condition which should be considered in patients with splenomegaly and cytopenia. Here, we describe brucellosis associated HLH in a 31 year-old man. The patient was admitted to our hospital with fever, sweating, and fatigue. Physical and laboratory findings revealed splenomegaly, pancytopenia, elevated serum transaminases, triglycerides, lactate dehydrogenase, and ferritin, and bone marrow hemophagocytosis. The Brucella agglutination test was positive. The patient improved after treatment with Rifampin and doxycyclin.

Sarcoidosis is a multivisceral granulomatosis of unknown aetiology which may have various clinical and radiological manifestations. Cerebral sarcoidosis, although rare, can appears as a misleading pseudotumor. We report the case of a young Tunisian adult hospitalized for intracranial hypertension associated with pseudotumoral lesion on radiology, which was revealed to be systemic sarcoidosis.

Celiac disease (CD) is an autoimmune disease affecting multiple organs. It often presents as gastrointestinal manifestations associated with malabsorption. However, serosa involvement uncommonly reveals this enteropathy, making the diagnosis difficult. We here report the case of JA, aged 63 years, admitted to hospital to detect the cause of malabsorption syndrome associated with polyserositis signs including pleurisy, pericarditis, ascites and hydrocephalus. The diagnosis of CD was based on endoscopic signs without serology tests. Patient's evolution was partially favorable, due to lack of compliance with a gluten-free diet. Our study reports the first case of CD revealed by polyserositis. CD should be suspected in patients with malabsorption syndrome, in the absence of evocative signs.

Background: Lung damage during amyopathic dermatomyositis (ADM) associated with auto antibodies anti MDA-5 is serious. We report a rare observation of a severe ADM associated to anti MDA-5 antibodies complicated with diffuse interstitial lung disease (ILD) rapidly extensive and fatal., Observation: We report the observation of a Tunisian adult who was admitted for ADM. The anti MDA-5 antibodies were detected. He developed an ILD rapidly extensive to fibrosis. Corticosteroids were unefficient and he deceded of pneumomediastin and refractory respiratory distress., Conclusion: This observation illustrates the severity of ADM with anti MDA-5 antibodies. Every clinician should detect any ILD to avoid the progression to fibrosis.

Background: The amyloidosis is one of the histologic lesions the most frequently associated to the aging., Aim: To identify the several etiologies of amyloidosis in elderly patients according to immunohistochemical type., Methods: Retrospective study on 10 years, in Internal medicine and Nephrology department in Charles Nicolle Hospital. Tunis. Tunisia. Diagnosis of amyloidosis was retained after histological confirmation with specific colorations, in patients aged 65 years or more at the diagnose of amyloidosis., Results: The study enrolled 51 patients with amyloidosis. In 67% of cases it was AA amyloidosis. The etiology the most frequently observed with this type was the tuberculosis, followed by chronic pulmonary infections. We retained diagnose of non AA amyloidosis in 21% of patients. The multiple myeloma has been the most frequent etiology observed, but no cause was identified at about half of patients. Twelve per cent of amyloidosis were not typed., Conclusion: From our study, we can remark the high predominance of AA amyloidosis, probably because of frequency of tuberculosis which is still high in our country, this is not in accordance with occidental data, were AL amyloidosis and senile amyloidosis predominate in elderly.

Background: Renal involvement in the Behcet's disease is rare. The clinical features vary from urinary sediment's abnormalities to ESRD., Aim: We propose to study the clinical, biological and histological data, the therapeutic management and the prognosis of patients., Methods: We report a retrospective study including 8 patients representing 1.23 % of cases., Results: The average age of the patient was of 37 +/- 12. 35 years with a clear male prevalence. Urinary signs were discovered fortuitously by the strips in the majority of the cases after an average of 18 months. It's about proteinuria and hematuria. Renal insufficiency and hypertension were rare. Pathological study highlighted 3 cases of amyloidosis, 2 cases of IgA nephropathy, 1 case of minimal change disease, 1 case of endo and extracapillary glomerulonephritis and 1 case of interstitial nephropathy. Patients having GN were treated by corticoids and immunosuppressive agents and those having an interstitial nephropathy were treated symptomatically with good evolution in the majority of the cases. Only one patient is dead, he had amyloidosis. Prognosis depended on the precocity of the diagnosis, the histological type and the treatment., Conclusion: The renal involvement during Behçet's disease is rare. Amyloidosis and Ig A nephropathy are the most frequent. Treatment is still controversial.

Slippage of the upper femoral epiphysis can occur in association with multiple endocrine imbalances. A case of slipped femoral epiphysis with primary hyperparathyroidism is reported. The patient was an adolescent, 16 Years of age, who presented bilateral slipped epiphysis. Investigation showed that he had hypercalcemia (3.1 mmol/l) related to primary hyperparathyroidism. A parathyroid adenoma was removed. Outcome was favorable and the slipped femoral epiphyses did not require a specific treatment.

We report two cases of Grave's disease (GD) caracterized by the succession of hypothyroid and hyperthyroid states. Case 1: A 32 years old woman, has presented initially a typical GD with hyperthyroidism. Grave's ophtalmopathy and homogenous goiter. Four months later, she presented a spontaneous hypothyroidism necessiting treatment with thyroxine and a severe myasthenia gravis. More later (6 months), she experienced symptoms of hyperthyroidism after thymectomy. The level of anti-thyrotropin-receptor antibodies (TSab) was very high (141 UI/I, NV < 10). Case 2: A 29 years old woman has been treated by thyroxine (150 microg/day) for a primary hypothyroidism. Ten months later, she presented symptoms of hyperthyroidism even after stoppage of thyroxine. TSH value was decreased (TSH < 0.05 microU/ml) and FT4 level was raised (FT4 = 25.5 pmol/l). The thyroid antibodies were positive. We discuss, after review of the litterature, the physiopathological mecanisms of these changes in the thyroid state, particularly the role of the blocking and stimulating anti-thyrotropin-receptor antibodies.

Suprasellar germinomas are frequent in childhood and adolescence, particularly in male sex. The clinical and neuroendocrine abnormalities depend of tumor localization: Increased intracranial pressure, visual disturbances, hypopituitarism, Parinaud syndrome. We report two cases of suprasellar germinoma in young male patients (16 and 18 years old). The first patient hrad corticotorpin insufficiency and clinical signs of hypothyroïdism and hypogonadism. The second had central hypocorticism, hypothyroïdism and hypogonadism associated with central diabetes insipidus and hyperprolactinemia. The diagnosis of germinoma was confirmed after surgery by anatomopathologic examination in the first case and by stereotaxic biopsy in the second case. Treatment by radiotherapy improves prognosis of this disease.
