ABSTRACT

Coronavirus disease 2019 (COVID-19) was first reported in December 2019. The disease is caused by severe acute respiratory syndrome virus corona virus 2 (SARS-CoV-2). Mild respiratory symptoms are the most common manifestations of SARS-CoV-2, but new signs are constantly being discovered as it spreads. Disorders of sodium balance are increasingly described in patients with SARS-CoV-2. We report, here, the cases of two patients presented with COVID-19 and in whom we discovered sodium disorders. The first patient is a 74-year-old man who presented with fatal hypernatremia. The second patient is a 66-years-old man presented with COVID-19 and euvolemic hyponatremia attributed to syndrome of inappropriate anti-diuretic hormone secretion (SIADH). This hyponatremia persisted long after the respiratory signs disappeared. Sodium balance disorders are increasingly described in the literature; special attention should be paid to the electrolyte status of COVID-19 patients. Pathophysiological mechanisms associating SARS-CoV-2 with these disorders are being studied.

ABSTRACT

BACKGROUND: Neuropathy is a frequent complication in diabetic patients with variable clinical presentations and evolutions. AIM: The purpose of the study was to specify the clinical features of diabetic third nerve palsy, to assess the risk factors and to observe its evolution. METHODS: We report a series of 11 diabetic patients with oculomotor paralysis collected in the department of endocrinology and diabetology of FarhatHached Hospital of Sousse between 1996 and 2005. RESULTS: Our study was about 6 men and 5 women with an average age of 63.6 ± 13.7 years. All patients had type 2 diabetes.  Eight patients presented with diplopia, three with periocular pain and 6 with headache. The oculomotor palsy was unilateral in all cases. All patients were in glycemic imbalance at the time of the diagnosis of ptosis and they were at high cardiovascular risk. The evolution under optimal equilibrium of diabetes and control of cardiovascular risk factors was marked by regression and disappearance in 4 patients, homo or contralateral recurrence in 4 patients and persistence of the palsy in 1 patient. CONCLUSION: Glycemic equilibrium and ischemic phenomena due to cardiovascular risk factors are at the root of these oculomotor paralyses in diabetic patients. The evolution of diabetic mononevritis remains unpredictable despite the control of blood glucose levels and cardiovascular risk factors.

ABSTRACT

Macroprolactinemia is a polymeric form of prolactin-release, causing mildly symptomatic clinical pictures. The former can be isolated or associated with other causes of hyperprolactinemia. The association with an empty sella syndrome is rare. We report a case of a female patient discovered with this association. It's about a female patient 47 years old, followed up since the age of 31 years for bilateral galactorrhea and a spaniomenorrhea. There has been no associated drug intake. Her exploration has showed a serum prolactin level of 635 mIU/L. Thyroid test results were normal T4 = 10,2ng/L and TSH = 1.76 mIU/L. A brain scan has showed an empty sella turcica. Despite the unchanged levels of prolactinemia, the evolution under dopaminergic 5 mg /D has been marked by the occurrence of a pregnancy with persistent moderate hyperprolactinemia in the postpartum. Chromatography has showed a predominance of the macroprolactin form with: Prolactin monomer at 4.8%, Big Prolactin at 5% and Big Big Prolactin at 83%, thus stopping bromocriptine. Our observation suggests that macroprolactinemia can be associated with conventional etiologies of moderate hyperprolactinemia as the empty sella syndrome. Its detection would prevent the use of dopaminergic therapy which seems not useful.

ABSTRACT

Prolactin-secreting adenoma is rare in elderly women. Patient's clinical picture may be confused with that of menopause, making diagnosis sometimes difficult. We report the case of a 57-year old woman with a 2-year history of secondary amenorrhea without hot flushes associated with galactorrhea in order to highlight the peculiarities of prolactin-secreting microadenomas. Physical examination confirmed the diagnosis of galactorrhoea and biology showed hyperprolactinemia at mIU/L, FSH = 15.1 IU/L and LH = 4,1 IU/L. Pituitary MRI showed left adenoma measuring 8 mm. Patient's evolution under dopaminergic treatment was marked by the recovery, for a transitional period, of mestrual cycles and the occurrence of hot flushes, normalization of prolactin levels and reduction of adenoma size.
