    La survenue d'un syndrome polyuro-polydipsiqueavec des urines hypotoniques nĂ©cessite une stratĂ©gie diagnostique rigoureuse. Le but de cette Ă©tude Ă©tait d’étudier les modalitĂ©s de diagnostic du diabĂšte insipide central. A travers une Ă©tude rĂ©trospective de 41 cas de diabĂšte insipide central(DIC) colligĂ©s au service d’Endocrinologie Ă  l’hĂŽpital de la Rabta de Tunis, allant de l’annĂ©e 1990 Ă  l’an 2013,nous avons relevĂ© les circonstances de dĂ©couverte du DIC, les anomalies du bilan antĂ©-hypophysaire etde l’imagerie hypophysaire. Le DIC Ă©tait post opĂ©ratoire chez 20 patients. La diurĂšse moyenne de 24 heures Ă©tait significativement plus Ă©levĂ©e chez les patients ayant un DIC en dehors d’un contexte chirurgical. L’épreuve de restriction hydrique Ă©tait concluante chez tous les patients qui en ont bĂ©nĂ©ficiĂ©. En dehors d’un contexte neurochirurgical, les causes infiltratives Ă©taient retrouvĂ©es chez 6 patientset les causes tumorales chez 6 patients. Le DIC Ă©tait associĂ© Ă  une selle turcique vide dans 1 cas et idiopathique chez 3 malades. L’imagerie par rĂ©sonnance magnĂ©tique hypothalamo-hypophysaire et le bilan antĂ©-hypophysaire sont systĂ©matiques en dehors d’un contexte de chirurgie hypophysaire et d’une polydipsie primaire Ă©vidente.

    Les lĂ©sions du pied chez le diabĂ©tique sont associĂ©es Ă  une importante morbimortalitĂ©. Leur prĂ©vention passe en particulier par des soins appropriĂ©s des pieds. Objectif : L’objectif de notre Ă©tude Ă©tait d’évaluer la pratique des soins des pieds par les diabĂ©tiques Ă  haut risque podologique dans un centre hospitalo-universitaire de Tunis. MĂ©thodes : Cinquante-deux diabĂ©tiques Ă  haut risque podologique, hospitalisĂ©s au service d’endocrinologie de l’hĂŽpital La Rabta de Tunis entre Janvier 2014 et Mai 2014, ont rĂ©pondu Ă  un questionnaire Ă©valuant leur pratique des soins des pieds. Un score global allant de 0 Ă  10 a Ă©tĂ© Ă©tabli. Nous avons considĂ©rĂ© comme Ă©tant Ă  haut risque podologique les diabĂ©tiques dont le grade de risque podologique Ă©tait de 1, 2 ou 3 selon la classification du groupe international de travail sur le pied diabĂ©tique (IWGDF). Les patients ayant une pratique de soins de pieds insatisfaisante (score < 5) ont Ă©tĂ© comparĂ©s Ă  ceux ayant une pratique satisfaisante (score ≄ 5) en fonction de diffĂ©rents facteurs sociodĂ©mographiques et liĂ©s au diabĂšte. RĂ©sultats : Le score moyen obtenu par nos patients en rĂ©ponse au questionnaire Ă©tait de 4,9/10 (extrĂȘmes de 1 Ă  9). Le score Ă©tait infĂ©rieur Ă  5 chez 42,3 % des patients entre 5 et 7 chez 40,4 % des patients et supĂ©rieur Ă  7 chez 17,3 % des patients. Les facteurs associĂ©s Ă  une pratique insatisfaisante des soins des pieds Ă©taient le bas niveau socioĂ©conomique (p = 0,009) et le fait de n’avoir jamais bĂ©nĂ©ficiĂ© d’une sĂ©ance d’éducation thĂ©rapeutique visant Ă  prĂ©venir la survenue de lĂ©sions du pied (p = 0,032). Conclusion : Nos rĂ©sultats rĂ©vĂšlent que la pratique des soins des pieds par les diabĂ©tiques Ă  haut risque podologique est trĂšs insuffisante. Des mesures prĂ©ventives et Ă©ducatives en matiĂšre de soins de pieds sont urgentes afin d’amĂ©liorer le pronostic podologique de ces patients

    Isolated corticotrope deficiency is a rare cause of secondary adrenocortical insufficiency. Its occurrence in patients with Down syndrome is exceptional. Herein, we report a case of an isolated corticotrope deficiency diagnosed at the age of 33 years in a woman with Down syndrome and discuss its possible mechanisms. A 33-year-old woman with Down syndrome was referred to our department for the investigation of low blood pressure. She complained of asthenia, dizziness, and palpitation with arterial hypotension for the past 4 years. The thyroid function was normal and anti-thyroperoxidase antibodies were negative. The peak of cortisol level in response to the insulin-induced hypoglycemia test was 9.4 Όg/dl. ACTH level was normal, indicating corticotrope deficiency. Other pituitary hormones were normal. Magnetic resonance imaging scan revealed a partially empty sella turcica. Genetic analysis showed no mutations and no copy number variants of the TBX19 and NFKB2 genes. The mechanism of isolated corticotrope deficiency is unclear, but it may be induced by autoimmune mechanism in similar to other disorders of patients with Down syndrome

    Dopamine agonists are the first-line treatment of prolactinomas. The risk of developing de novo psychiatric symptoms during dopamine agonist therapy is low. Herein, we report the case of a 42-year-old woman with a giant prolactinoma who developed a psychiatric disorder after 1 day of cabergoline therapy initiation. She presented with amenorrhea, galactorrhea, headaches, and disturbed vision. Biological investigations revealed hyperprolactinemia (2975 ng/ml) with gonadotropin deficiency. Pituitary MRI showed a giant pituitary adenoma. The patient was treated with cabergoline at the dose of 1 mg twice weekly. One day after the treatment initiation, she developed acute delirium with temporospatial disorientation and compulsive medication use. These symptoms disappeared 1 week after the reduction of the dose of cabergoline. Patients with hyperprolactinemia receiving an initial high dose of cabergoline may develop changes in mood and behavior regardless of prior psychiatric history

    Les capsules vidĂ©o sont de plus en plus utilisĂ©es dans l’éducation thĂ©rapeutique. L’objectif de notre Ă©tude Ă©tait d’évaluer l’impact d’une vidĂ©o Ă©ducative sur l’amĂ©lioration des connaissances des diabĂ©tiques Ă  haut risque podologique. MĂ©thodes : Étude quasi expĂ©rimentale menĂ©e chez 40 patients diabĂ©tiques Ă  haut risque podologique selon la classification du groupe international de travail sur le pied diabĂ©tique (IWGDF). Une Ă©valuation des connaissances sur les moyens de prĂ©vention des lĂ©sions du pied a Ă©tĂ© rĂ©alisĂ©e Ă  l’aide d’un questionnaire prĂ©Ă©tabli avant et aprĂšs visionnage d’une vidĂ©o Ă©ducative. RĂ©sultats : L’ñge moyen des patients Ă©tait de 57,8 ± 1,5 ans (22 femmes et 18 hommes). L’anciennetĂ© moyenne du diabĂšte Ă©tait de 15,6 ± 8,8 ans. Le niveau de connaissance Ă©tait classĂ© mĂ©diocre (score entre −14 et 0) chez 13 % des patients, moyen (score entre 1 et 11) chez 50 % des patients et bon (score > 11) chez 37 % des patients. AprĂšs visionnage de la vidĂ©o, le score moyen d’évaluation des connaissances des patients est passĂ© de 10,4 ± 4,5 Ă  16,8 ± 4,0 (p  20 % du score d’évaluation des connaissances Ă©tait plus frĂ©quemment observĂ©e chez les sujets dont le niveau de connaissance initial Ă©tait classĂ© moyen ou mĂ©diocre (p < 0,001) et chez ceux ayant un bas niveau d’instruction (p = 0,07). Conclusion : Les supports vidĂ©o disponibles en ligne reprĂ©sentent un moyen efficace pour amĂ©liorer le niveau de connaissance des diabĂ©tiques Ă  risque podologique sur les moyens de prĂ©vention des lĂ©sions du pied, en particulier, si le niveau de connaissance initial est faible et en cas de bas niveau d’instruction

    A Case of Von Hippel–Lindau Disease with Bilateral Pheochromocytoma and Ectopic Hypersecretion of Intact Parathyroid Hormone in an Adolescent Girl

    Von Hippel–Lindau disease is an autosomal dominant inherited syndrome predisposing to a variety of highly vascularised tumors in different organs. Although bilateral pheochromocytoma was reported in patients with von Hippel–Lindau disease, the coexistence of primary hyperparathyroidism is not a common condition. We report an observation of a primary hyperparathyroidism secondary to an ectopic secretion of intact parathyroid hormone in a 17-year-old girl with von Hippel–Lindau disease and bilateral pheochromocytoma. She presented with a newly diagnosed diabetes mellitus and a severe arterial hypertension. Blood tests disclosed hypercalcemia with increased intact PTH level. Cervical ultrasound and sestamibi scintigraphy were normal. Twenty-four-hour urinary normetanephrine level was highly elevated pointing to a catecholamine-secreting tumor. The abdominal computed tomography showed bilateral adrenal masses. MIBG scintigraphy exhibited a high accumulation of the tracer in both adrenal tumors. Genetic testing revealed a mutation of the VHL gene. The patient underwent a bilateral adrenalectomy. The postoperative outcome was marked by normalization of blood pressure, blood glucose, calcium, and PTH levels. In our case, the elevation of intact PTH and its spontaneous normalization after surgical treatment of pheochromocytomas confirms its ectopic secretion

    Background: The objective of the study is to determine the factors associated with the level of knowledge of Tunisian type 1 diabetic (T1D) patients in adulthood. Methods: This is a cross-sectional study including 93 T1D patients over 18 years old. The knowledge assessment was carried out by a questionnaire rated out of 20 points. The subjects with an „unsatisfactory” level of knowledge (score &lt; 10/20) were compared with subjects whose level of knowledge was „satisfactory” according to their socio-demographic, clinical, and paraclinical characteristics. Results: The mean age of the patients was 37.2 ± 12.4 years. The level of knowledge was „unsatisfactory” in 21 patients (23%). After univariate analysis, an „unsatisfactory” level of knowledge was associated with a low level of education (p = 0.001), a poor socioeconomic level (p = 0.03), a poor glycemic control (p = 0.003) and the absence of self-monitoring (p = 0.002). After multivariate analysis, only a low level of education and a lack of practice of self-monitoring were associated with an „unsatisfactory” level of knowledge (respectively p = 0.03 and 0.03; adjusted OR [95% confidence interval] = 7.3 [1.2–43.5] and 13.7 [1.3–143.3]). Conclusions: The factors independently associated with the level of knowledge in adult T1D patients are the level of education and the practice of self-monitoring. This encourages better tailoring of educational messages to patients with low levels of education and suggests that a better level of knowledge ensures better self-management of diabetes. However, the relationship with the quality of glycemic control remains uncertain
