[Toxic nodular goiter]. / Les goîtres nodulaires toxiques.

INTRODUCTION: To date no study in our country was specifically dedicated on toxic nodular goiter. They were just mentioned in generally studies about hyperthyroidism. METHOD: The authors report a retrospective series of 62 cases of toxic nodular goitre collected between 1979 and 1999 at the internal medical clinic of Dakar teaching hospital. The diagnostic of toxic nodule was retained on following criteria: to existence of one or several thyroid nodule with signs or thyrotoxicosis, the existence of a hyperfixating nodule at 131 iodine scintigraphy. Increasing of T3 and/or T4 thyroide hormone. The aims of the study was to analyse the epidemiological, clinical, and therapeutics aspects. RESULTS: We are collected 49 cases of solitary nodule (79.03%) and 13 cases of multi nodular goitre (20.97%). In the cases of solitary nodule, mean age was 40 years, sex ratio of 0.04 (47 female, 2 men). The nodule was clinically diagnosed in 47 cases (95.9%) and extinctive in 73.5%. 34.3% of patients have cardiothyreosis. In the cases of multi nodular goitre mean age was 45 years, all cases were female, goitre was clinically identified in 95.3% (12 patients) and 46.5% had cardiothyreosis. 62% of patients were lost to follow up during medical treatment. Only 2 patients on the 37 who were addressed for surgery come back after thyroidectomy. CONCLUSION: This study confirm the predominance of toxic nodular goitre in young female, its severity related to cardiothyreosis and underlines the difficulties limited to the therapeutical care.

[Diabetic pregnancy in Senegal (years 1980 to 1989)]. / La grossesse diabétique au Sénégal (Années 1980 à 1989).

INTRODUCTION AND OBJECTIVES: Diabetic Pregnancy Prognosis in Seventies is it better in Eighties because of Patient Education? METHODOLOGY: Retrospectively, since 1980 to 1989, in Women in status to breed, Diabetic Pregnancy was screened in our Department. W.H.O.'s (1980) Diabetes Mellitus Criterias, PEDERSEN's Criterias, White's Classification were used. Studied Parameters were etiologic factors (age, type, Diabetes oldness and control), former and present Evolution of Pregnancies (term and pregnancy's product). RESULTS: A--In Global Study, 15.07% Diabetic Pregnancies were observed: 22 (37%) Insulin Dependent and 38 (63%) Non Insulin Dependent. The global mean of age was 31 years; Diabetic Mellitus was less than 10 years old in 90% cases whatever the type. Their control was not good (Glycemic Control < 1.4 g/l in less than 50%). Diabetes complications were nephropathy (13.6% and 8%), retinopathy (13.6% and 18.5%), arterial hypertension (0% and 26.32%), cetoacidosis (31.42% and 0%), urinary tract infection (18% and 0%) respectively in Insulin Dependent and Non Insulin Dependent Pregnancies. Near a third (31.6%) of Insulin Dependent and a third (33.41%) for Non Insulin Dependent were of D, F, H White's Class. Multipares were often Non Insulin Dependent and inversely Insulin Dependent frequently paucipare. Former Pregnancies had near 25.5% interrupted term in Insulin Dependents. Present Pregnancies have given 28.5% and 32% of Normal Children: 14.25 and 12% of Abortions and 14.25% and 6% of Spontaneous Premature Parturitions respectively in Insulin Dependents and Non Insulin Dependents. B--In Analytic Study of Foetopathies, bad Prognosis Factors were high Maternal Age, Multiparity, bad Glycemic Control whatever Diabetes type. For Insulin Dependent, Negligency was added and for Non Insulin Dependent, Obesity, Arterial Hypertension and all PBSP. DISCUSSION AND CONCLUSION: A relatively mild Diabetic Pregnancy Prognosis in our areas with limited means has been observed despite of Patients Education.

[Evaluation of thrombotic risk in type 2 diabetes: determination of platelet factor 4 and beta thromboglobulin]. / Evaluation du risque thrombotique dans le diabète de type 2: dosage du facteur 4 plaquettaire et de la bêta thromboglobuline.

We achieved the dosage of platelet factor 4 (PF 4) and beta thromboglobulin (B-TG), two proteins stored in platelet alpha granules and released from the platelets when activated. These proteins were studied by ELISA technics in patients with type 2 diabetes without any complications (n = 32), with thrombotic complication (n = 32) and in a healthy control group (n = 32). The diabetic patients with complications had significantly elevated plasma levels of PF4 and B-TG compared with diabetic patients without complications, whereas levels of these proteins where normal in control group. These high rates of PF4 and B-TG were significantly related to a disturbance of lipidic balance. Our data suggest that platelet hyperactivation may be a reliable element in the pathogenesis of thrombotic complications in type 2 diabetes.

[Frequency of micoalbuminuria during diabetes in Dakar (Senegal)]. / Frequence de la microalbuminurie au cours du diabète à Dakar (Sénégal).

Nephropathy is one of the complications occuring during diabetes diagnosed via microalbuminuria. From 1992 to 1999, five hundred and eighty seven (587) diabetic patients were recruited in groups A (n = 270) and B (n=317). Microalbuminuria was determined by immunonepheletry for A and immunoturbidimetry for B. The results pointed out respectively 15.5% and 20.19% pathological cases (NS). Considering the distribution of patients with microalbuminuria according to the type of diabetes there were 16.12% type 1 and 15.07% type 2 in group A against 22.60% and 18.13% in group B ; no stastically significant differences were observed either in the same group or from one group to another. These frequencies would reflect the situation in the nineties; they are lower than those encountered in other populations. Nevertheless monitoring is needed through a regular schedule to prevent nephropathy.

[Ketoacidosis in type 1 diabetes mellitus: 73 cases in Dakar]. / Acidocetose Chez Le Sujet Diabetique De Type 1 : A Propos De 73 Cas Colliges A Dakar.

INTRODUCTION: The follow-up of diabetes mellitus in children and teenagers remains a challenge. Ketoacidosis is the most frequent acute metabolic complication and is of bad prognosis. The objective of this study was to evaluate etiologicals factors of decompensation and evolutions in type 1 diabetes. PATIENTS AND METHODS: We conducted a transversal and prospective study from January 2009 to October 2010. All type 1 diabetic patients hospitalized for ketoacidosis had been included. For every patient, we have studied the epidemiologicals, etiologicals and clinicals factors as well as the outcomes. RESULTS: The prevalence was to 55.3 % among all ketoacidosis. Sex-ratio (Men/Women) was 0.78, mean age to 25.73 years and mean duration of diabetes was 3.9 years. Ketoacidosis was inaugural in 26 % of cases. Except Kussmaul dyspnea, prevailed digestives symptoms (87.6 %). Coma was noted in 82.1 % among whom 54.7 % had no previous diabetic follow-up. A decompensation factor was found in 93.1 % of which an infection (78 %) or stop insulin (53.42 %). Prevailing infectious sites were urogenitals (24.6 %), respiratories (20.5 %). The outcome was fatal in 6.8 % of the cases. It was about 24.3 years middle-aged, 1,6 year diabetes mellitus mean duration, without regular follow-up in 80 % of the cases. Other associated factors were coma stage 2 or 3 (80%), infection (60 %), hypokalemia (40 %). CONCLUSION: Ketoacidosis is frequent in type 1 diabetic patients and has a bad prognosis. Infection and stop insulin are major factors of decompensation. Its prévention requires an adapted therapeutic education associated to a regular follow-up of patients.

Les goitres nodulaires toxiques

Introduction : Jusqu'ici; aucune etude dans notre pays n'avait porte specifiquement sur les goitres nodulaires toxiques. Elles n'ont ete citees que dans des etudes generales des hyperthyroidies. Methodes : Il s'agit d'une etude retrospective de 62cas de goitres nodulaires toxiques colliges entre 1979 et 1999 a la clinique medicale 2 du CHU de Dakar. Le diagnostic de nodule toxique a ete retenu sur les criteres suivants : la coexistence d'un ou plusieurs nodules thyroidiens et de signes de thyrotoxicose; l'existence d'un nodule hyperfixiant a la scintigraphie thyroidienne a l'iode 131; l'elevation des hormones thyroidiennes T3 et/ou T4. Nous nous sommes interesses aux aspects epidemiologiques; cliniques; aux complications et aux aspects therapeutiques et evolutifs. Resultats : Il s'agissait de 49 nodules uniques (79;03) et de 13 goitres multi nodulaires (20;97). Dans les cas de nodules uniques; l'age moyen etait de 40 ans; le sexe ratio de 0;04 (47 femmes; 2 hommes). Le nodule etait cliniquement decelable dans 47 cas (95;9) et extinctif dans73;5; La cardiothyreose existait dans 34;6des cas. En cas de goitre multi nodulaire; l'age moyen etait de 45ans; le sexe feminin dans tous les cas. Le goitre etait cliniquement decelable chez 12 patients (95;3). La cardiothyreose existait dans 46;15des cas. 62des patients ont ete perdus de vue en cours de traitement d'equilibration de l'hyperthyroidie. Sur les 37adresses en chirurgie; seuls deux ont ete revus apres thyroidectomie. Conclusion : Cette etude confirme la predominance du goitre nodulaire toxique chez la femme jeune; sa gravite par la frequence de la cardiothyreose et souligne les difficultes liees a la prise en charge therapeutique
