[Pseudoainhum and peripheral neuropathy].

BACKGROUND: Pseudoainhum is a rare disease characterised by gradual fibrous constriction of the fingers and/or toes eventually resulting in their amputation. In this article, we report the first case seen in Morocco, highly unusual in terms of its severity. CASE REPORT: A 46-year-old woman with no toxic habits was hospitalised for spontaneous amputation of the fingers and toes. This condition began when the patient was 12 years old with the appearance of a circular constriction band at the base of the fifth toe, eventually resulting in its loss. The patient gradually lost all her other toes and fingers except for the first joint of her left index finger. There was no family history of any similar condition. Clinical examination also revealed perforating plantar disease in two of the stumps and peripheral neuropathy in all four limbs, comprising predominantly axonal disease responsive to electromyogram. Amputation of the index finger was completed and histological examination of the removed section showed nothing unusual, with no signs of diabetes. DISCUSSION: The peculiarity of our case resides in the exceptional severity of these amputations and their association with isolated polyneuropathy. Pseudoainhum has been described chiefly in patients with congenital keratoderma, certain systemic diseases, diabetes and alcohol dependence. A number of etiopathogenic hypotheses have been suggested: traumatic, infectious, vascular, neurological and genetic processes.

[Pruritus sine materia: a prospective study of 95 patients].

PURPOSE: To describe the nature and the frequency of systemic diseases responsible for the pruritus sine materia. Value of this sign as a marker of malignancy. METHODS: Prospective study undertaken over five years (1996-2001). INCLUSION CRITERIA: generalized aspect of the pruritus and absence of specific primitive cutaneous lesions of an itching dermatosis. Parameters taken from the data of the anamnesis and the physical examination. Standard biologic and morphologic investigations were done. RESULTS: Ninety-five patients included (54 men, 41 women) of 55.5 years average age +/-18.1. In 24 patients, traditional hospitalisation with one average duration of eight days stay +/-3.15 was necessary. In 38 cases (40%), a systemic cause was found. The main conditions were: toxocariasis (8 cases), hematologic diseases (7 cases), chronic renal failure (6 cases), hypothyroidism (5 cases) and iron deficiency (5 cases). A neoplasm was found in eight cases (8,42%): seven hematologic malignancy (3 myeloma, 2 Hodgkin's diseases, 2 myeloproliferative syndromes) and one solid cancer (pulmonary adenocarcinoma). CONCLUSION: A systemic aetiology was observed in 38 cases (40%). The toxocariasis an underestimated disease comes at the first place. The pruritus sine materia can hide an hematologic malignancy.

Pharmacological treatment of hypertension in pregnancy.

The hypertensive disorders of pregnancy complicate 5-10% of pregnancies. Of these disorders 70% are pregnancy related (preeclampsia-eclampsia and gestation hypertension) and 30 % are a pre-existing hypertensive condition (chronic hypertension). These disorders are associated with maternal and fetal complications and have a substantial economic impact. This review examined the pharmacological treatment of the hypertensive disorders of pregnancy. There is a general consensus that anti-hypertensive should be given with severe hypertension and this should be in the hospital. The value of antihypertensive drugs in pregnant women with mild hypertension continues to be an area of debate that the evidence is too scanty to securely evaluate the clinical benefits of treating mild hypertension during pregnancy. The choice of the antihypertensive agents depends on individual clinician preference, the specified maternal and foetal benefits and the reproductive complications (teratogenisity, fetotoxicity and neonatal toxicity) of each particular agent. There are unequivocal evidences that Magnesium sulphate is superior to other agents in reducing recurrent eclamptic seizures. There is a strong recent evidence recommended that magnesium sulphate should be considered for women with pre-eclampsia for whom there is concern about the risk of eclampsia.

Reducing the dose of gonadotrophin-releasing hormone agonist on starting ovarian stimulation: effect on ovarian response and in-vitro fertilization outcome.

The aim of this study was to examine if lowering the dose of gonadotrophin-releasing hormone agonist (GnRHa) on starting ovarian stimulation could be beneficial in in-vitro fertilization (IVF) programmes. A total of 64 normally ovulating patients entering an IVF programme were randomized to receive GnRHa (nafarelin acetate/Synarel) as an intranasal spray commencing in the midluteal phase, either at a dosage of 200 microg three times daily until the day of human chorionic gonadotrophin (HCG) administration, or to be reduced to 200 microg twice daily as ovarian stimulation was initiated. Patients in both groups were below 35 years with a body mass index below 30. All patients received three ampoules of Metrodin HP per day. Blood samples were taken on the day of HCG administration to measure luteinizing hormone (LH), oestradiol, and progesterone. LH and oestradiol were found to be significantly higher in the lower Synarel dose group. Our results show that reducing the GnRHa dose during ovarian stimulation in IVF might be beneficial in terms of significantly more oocytes recovered, and significantly greater number of embryos available for transfer and freezing, with no incidence of premature luteinization.
