[Mucormycosis in the diabetic patient].

INTRODUCTION: Mucormycosis is a rare, devastating, fungal infection, which disproportionately affects non-controlled diabetic patients, notably during ketoacidosis. It can be manifested in rhinocerebral, but also pulmonary and disseminated forms. OBSERVATIONS: Four consecutive diabetic patients who were admitted to the Farhat Hached Hospital, Sousse, Tunisia, between January 2001 and November 2002, are presented. Three patients exhibited ketoacidosis and one renal failure with hyperosmolarity. Infection was limited to the sinuses in two cases, to lower respiratory tract in one case, and was probably disseminated in one case. Diagnosis was confirmed by mycological and histological findings in all cases. Systemic Amphotericin B was associated with surgical debridement of the lesions in patients with rhinocerebral involvement. DISCUSSION: Despite aggressive therapy, mortality was high (3 out of 4 patients). Mucormycosis remains a severe, frequently fatal disease in diabetic patients.

[Langerhans cell histiocytosis associated with pituitary stalk transection].

UNLABELLED: Clinical manifestations of hypothalamic-pituitary Langerhans'cell histiocytosis are commonly, diabetes insipidus and sometimes growth hormone deficiency. Their morphologic characteristics on magnetic resonance imaging are absence of posterior pituitary hyperintensity and thickening of the pituitary stalk. Pituitary stalk transection is characterized on magnetic resonance imaging by the absence of pituitary stalk visibility, hypoplasia of the anterior hypophysis and ectopic posterior pituitary hyperintense signal. This syndrome has been shown to be associated with either isolated growth hormone deficiency or multiple anterior pituitary hormone deficiency, but normal posterior pituitary function. CASE REPORT: We report our experience with a six-year-old boy who had been treated for three years for a multisystem Langerhans'cell histiocytosis with diabetes insipidus and who was admitted because of short stature. Endocrinological examinations demonstrated a profound growth hormone deficiency and a partial central hypocorticism. Magnetic resonance imaging showed pituitary stalk transection and a midline anomaly of the brain (Arnold Chiari type I malformation). CONCLUSION: Although, some events of his perinatal history lead to the hypothesis of a malformative origin, the progression of Langerhans' cell histiocytosis affected tissues to fibrosis, suggest that this disease is the cause of the patient's hypothalamohypophyseal lesions.

[Post-partum autoimmune thyroiditis in a patient presenting with Sheehan's syndrome].

A 30-year-old women developed post-partum thyroiditis associated with post- partum pituitary infarction. Pituitary stimulation tests demonstrated global pituitary deficiency but there was no thyrotropin response to TRH stimulation and free T4 was normal. Associated goiter and high circulating levels of microsomal antibodies led to the diagnosis of post-partum thyroiditis associated with pituitary deficiency. Two cases of this unusual association have been reported. The underlying pathogenesis might involve post-partum immunological rebound and/or hypocorticism-induced immunological disorders.

[Thyroid pseudo-nodules: 3 case reports].

The thyroïd pseudo-nodules constitute cervical lesions that can simulating neoplastic thyroid lesions either by their size or by their "cold" character in scintigraphy. We describe 3 cases of thyroïd pseudo-nodules collected in 10 years: a thyroid hydatid cyst, a schwannoma of the recurrent nerve and a thyroglossal duct cyst. Throw these observations, the authors discuss the problems of differential diagnosis set out with these pseudo-nodules. Although the diagnosis in the 3 cases, was histological after post operative exam, the authors insist throw a review of the literature, on the place of fine needle aspiration cytology in the therapeutic strategy that can show specific signs for some lesions. For the other cases, surgery resection is effected to eliminate malignant lesions who are the principal differential diagnosis of thyroid pseudo-nodules.

Primary amenorrhea-galactorrhea with hyperprolactinemia and huge pituitary enlargement in juvenile primary hypothyroidism.

We report a girl with juvenile primary hypothyroidism revealed by growth retardation and a syndrome of primary amenorrhea-galactorrhea with hyperprolactinemia and suprasellar pituitary enlargement. Resolution of the pituitary enlargement and the amenorrhea-galactorrhea syndrome occurred after thyroid hormone replacement. No similar observation has been reported earlier in juvenile hypothyroidism.
