[Etiologic and therapeutic aspects of acquired central diabetes insipidus].

Acquired central diabetes insipidus (CDI) is a rare disease due to anatomic lesions of the hypothalamo-pituitary system. We discuss the etiologic and therapeutic aspects of CDI. Through 5 cases and a review of the literature. We report: Two cases of Langerhans histiocytosis, a 21 year old man and a 37 year old women. The CDI was the only endocrine manifestation in the man, but it was associated with panhypopituitarism and infiltration of the thyroid gland by histiocytosis cells in the women. One case of suprasellar germinoma, a 18 year old adolescent had hypocorticism, hypothyroidism, and hypogonadism associated with CDI and hyperprolactinemia. One case of pituitary cystic lesion with extension to the suprasellar area, a 36 year old women presenting with hypocorticism, growth hormone deficiency, and hyperprolactinemia. One case of neuro-Behçet's disease in a 47 year old man. He presented with strokes and CDI. When the CDI is isolated Langerhans Histiocytosis should be considered first. The exploration of the hypothalamo-pituitary region using MRI showed different anatomic lesions in patients with CDI. It is very difficult to determine definitive diagnosis before surgery in the cases of cystic lesions.

[Ectopic thyroid: two cases].

Ectopic thyroid is a rare condition (1/4000 to 1/8000 among patients with hypothyroidism). The underlying etiological pathogenic mechanisms remain unknown. Diagnosis is established on the basis of imaging findings. We report two cases of hypothyroidism in adult females who had ectopic sublingual thyroid glands. The first patient was a 20-Year-old woman who had been treated for hypothyroidism since the age of 13 Years before the diagnosis of ectopic thyroid 7 Years later. In both patients, the thyroid gland was palpable. In the first patient the physical examination revealed an ectopic sublingual gland. Scintigraphy confirmed the diagnosis in both patients. The CT-scan and MRI were positive in the second patient. Hormonal substitution therapy using L-thyroixine was given.

[Obstructive acute renal failure revealing visceral leishmaniasis in a diabetic patient].

We report a case of a 22 years old type 1 diabetic man with a history of weight loss, weakness, anorexia, fever and recurrent urinary tract infection since February 2001. In April 2001, he presented anuria due to obstructive acute renal failure. Hepatosplenomegaly and lymphadenopathy were absent at physical examination. Laboratory tests revealed a high level of gamma globulin (53.4 g/l) and anaemia (haemoglobin 7.7 g/100 ml) without leukopenia and thrombocytopenia. CT scan showed multiple retroperitoneal lymphadenopathies causing compression of the two ureters, hydro-ureter associated with hydronephrosis, hepatosplenomegaly and multiple pulmonary nodes. Lymphadenopathies, anaemia, high level of gamma globulin, high titres of anti-leishmanial antibodies and the excellent outcome after treatment with meglumine antimoniate (Glucantime) confirmed visceral leishmaniasis. This report documented an unusual clinical presentation of Visceral leishmaniasis in a diabetic patient.

[Virilism during pregnancy].

We discuss the causes of virilism in pregnancy and the impact of hyperandrogeny on the female foetus. We report a case of virilism in a 28-year-old, gravida 1, para 1 patient with normal pregnancy and review the literature. After conception, the patient had been well until the 18th week of gestation, when she developed signs of virilization; her serum testosterone was markedly elevated. She delivered of a normal male infant at term. After delivery, signs of virilization regressed with normalization of testosterone level but a wide mass of the left ovary that persisted for 8 months. The histological study of the tumor showed luteinized thecoma. Luteomas and hyper-reactio luteinalis were the principal causes of virilism in pregnancy, thecomas are rare.

[Central diabetes insipidus with Behçet disease. A case report].

Vasculitis with central diabetes insipidus is a rare condition which must be recognized for an appropriate management. We report a case of Behçet disease with central diabetes insipidus. A forty seven year old men presented recurring oral and genital ulcers, skin lesions, polyarthralgia. Two years later, he showed right uveitis and central diabetes insipidus without dysfunction of the pituitary gland. Computed tomographic scan showed normal neurohypophysis and pituitary gland. Later on, he presented hemiplegia. The cerebral computed tomographic scan showed hypodense lesions. Central diabetes insipidus should not be systematically searched because it is a rare feature of the Behçet disease.

[Vasculitis with renal and pulmonary involvement in a patient receiving benzylthiouracil for Graves disease].

INTRODUCTION: Vasculitis is a rare complication of antithyroid drugs reported with propylthiouracil, carbimazole, methimazole and we describe the first case with benzylthyouracil. Renal involvement during thyroid auto-immune diseases and during vasculitis as complication of antithyroid drugs will be discussed. EXEGESIS: We present a case study of 28-year-old female patient with Graves' disease diagnosed in 1996 and treated by benzylthiouracil for 2 years. The thyroid function was poorly controlled, so surgical treatment was indicated in May 1998. One month later, she developed vasculitis with pulmonary and renal involvement. Her renal function deteriorated rapidly. On admission, the additional laboratory findings showed hematuria, proteinuria of 1.44 g/day and serum creatinine level at 1000 mumol/l. She had myeloperoxidase-anti neutrophil cytoplasmic antibody, antithyroglobulin and antimicrosome antibodies. A renal biopsy revealed pauci-immune crescentic glomerulonephritis with 75% sclerous crescents. Chest-X-ray showed unilateral alveolar shadowing and a bronchio-alveolar lavage revealed lymphocytic alveolitis. She was treated with high dose of prednisolone and cyclophosphamide. After a follow-up of 18 months, the serum creatinine level decreased at 186 mumol/l and chest-X-ray returned to normal. CONCLUSION: Some cases of vasculitis associated with anti-thyroid drug treatment are reported.

[Diabetic fibrous mastopathy: a case report].

Diabetic fibrous mastoplasty or diabetic fibrous breast disease is a benign condition rarely observed. First described in 1984, it can lead to misdiagnosis because it simulates breast cancer. Diabetic fibrous mastoplasty usually occurs in patients with autoimmune disorders, particularly in patients with longstanding and complicated insulin-dependent diabetes mellitus. We present a case of fibrous mastoplasty in a patient with insulin-dependent diabetes mellitus known for 17 years. The clinical and radiological features and the clinical course are illustrative. We discuss the different pathogenic theories put forward.

Renal replacement therapy for diabetic end-stage renal disease. Experience of a Tunisian hospital centre.

OBJECTIVE: To determine the epidemiological and clinical characteristics of 299 uremic diabetics at the initiation of renal replacement therapy (RRT) and to evaluate their morbidity and the factors influencing their mortality during the dialysis period. PATIENTS AND METHODS: All patients starting RRT for diabetic end-stage renal disease (ESRD) at Charles Nicolle Hospital of Tunis during a period of seven years (1990-1996) constituted the study population. During the follow-up period ended on December 31, 2000, all morbid events, hospitalizations and deaths were recorded. Multivariate analysis according to the Cox proportional hazards model was performed to identify the predictors of mortality. RESULTS: There were 238 type 2 (79.6%) and 61 type 1 diabetics (20.4%) representing 20.3% of all patients accepted for RRT. The mean age at the onset of RRT was 53.16 +/- 12.43 years (range: 23 to 80 years). A poor glycemic control was observed in 46.7% of type 2 diabetics and in 67.3% of type 1 diabetics (p=0.0055). A third of patients started RRT in emergency conditions and 91% required a temporary vascular access. At the time of onset of RRT, 86.7% of patients were hypertensive and 52.1% had a nephrotic syndrome. Blindness was observed in 22.9% of type 1 diabetics and in 7.5% of type 2 diabetics (p=0.0014). During the follow-up period, 217 patients died representing a rate of 22% patient-years, 26.7% of these deaths occurred during the first 3 months of RRT and 53% were attributed to infectious or cardiovascular complications. Actuarial survival rates were 68.4%, 59.6% and 45.3% at 1, 2 and 4 years, respectively. Age, co-morbidities and conditions of onset of RRT were independently correlated with survival time. CONCLUSION: Diabetes is a frequent cause of ESRD in Tunisia, the delayed referral to a nephrologist and coexistence of serious co-morbidities at the initiation of RRT resulted in a high rate of early death. Greater efforts should be made in our country in view of improving the quality of medical care of uremic diabetics before and during RRT.
