Background: Resistance to anti-thyroid drugs (ATDs) is a rare entity recently described. We report two African observations in the treatment of Graves' disease. Case 1: A 19-year-old Senegalese woman presented on admission with thyrotoxicosis syndrome associated with diffuse goitre and Grave's orbitopathy. TSH levels were low (0.005 mIU/ml; N = 0.27-4.20) and fT4 elevated (60 pmol/L; N = 12-22]. Combination therapy with propranolol (40 mg/day) and carbimazole (starting dose of 45 mg/day and increased to 60 mg/day) was initiated. In view of the persistence of symptoms despite good therapeutic compliance, carbimazole was replaced by methimazole with an initial starting dose of 40 mg/day, followed by 60 mg/day. Despite the change in therapy, clinical symptoms of thyrotoxicosis persisted, and fT4 levels remained elevated. The patient was diagnosed with resistance to ATDs in Graves' disease. Total thyroidectomy following 10 days of preoperative preparation with 1% Lugol's solution was performed successfully. Case 2: A 22-year-old woman was referred for continued management of Graves' disease with elevated thyroid-stimulating hormone receptor antibody (TRAb) levels (34 UI/mL; N < 1.75). Treatment included propranolol (80 mg/day) and carbimazole at an unusual dose of 80 mg/day. Combined therapy was clinically and biologically ineffective, with an fT4 level of 100 pmol/L [N: 12-22]. Upon admission, methimazole (40 mg/day) followed by propylthiouracil (800 mg/day) replaced carbimazole. Despite good patient compliance, the patient's symptoms remained unaltered and fT4 levels elevated. A total robot thyroidectomy using the right axillary approach was performed successfully after 10 days of preoperative preparation, including prednisone (40 mg/day
Nous rapportons 3 cas rares de plaies trachéales post-intubations découvertes au cours de chirurgie cervicale. Il s’agissait de 3 patientes âgées de 27, 30 et 42 ans admises au bloc opératoire pour une thyroïdectomie totale sous anesthésie générale indiquée devant un goitre hétéro-multi-nodulaire. L’intubation était orotrachéale à l’aide d’un guide rigide avec une sonde N°7,5 munie d’un ballonnet. Nous avons découvert en per opératoire une protrusion du ballonnet dans le champ opératoire à travers une effraction trachéale postéro-latérale. Le traitement avait consisté en une fermeture de la brèche trachéale dans 2 cas et une abstention chirurgicale dans le troisième cas suivi d’un drainage de la loge thyroïdienne. Les suites opératoires étaient simples. Les plaies trachéales post-intubations sont rares. Leur découverte per opératoire au cours d’une chirurgie cervicale est exceptionnelle. Les causes sont multiples. Il s’agit des difficultés d’intubation, d’une déchirure de la membraneuse par le bec de la sonde d’intubation, par un guide rigide, un effort de toux avec ballonnet gonflé au réveil, un sur-gonflage du ballonnet, de la modification structurale et anatomique de la trachée dans les goitres anciens. Il n’y a pas de consensus dans le traitement.
