| Hashimoto's thyroiditis and subacute thyroiditis were mostfrequently seen in inflammatory thyroid diseases.It is difficulty todifferentiate with thyroid carcinomas.This always result in surgerytreatment . Clinical doctors have not been agreeing on the type ofThyroiditis. Thyroiditis often be classified as three major categories ,namely, acute suppurative thyroiditis, subacute thyroiditis(SAT)and hashimoto's thyroiditis (HT) .Patients with acute suppurativethyroiditis are often combined with high fever and chill.Acute radiothyroiditis has the contract history of the radioactive maierials.It isnot difficute to make diagnoses. Subacute thyroiditis(SAT)andHashimoto's thyroiditis were most frequently seen clinically . Thereare a lot of similarities between the two diseases .So it is very importto diagnose and treat the two diseases accurately.The paper analyse 100 cases in order to discuss the commonfeatures of clinic characteristic, early diagnosis and principle oftreatment in subacute thyroiditis(SAT)and Hashimoto's thyroiditis(HT). Retrospectively analyse the diagnosis and treatment of 100cases those were comfirmed by pathological diagnosis , including 29with subacute thyroiditis(SAT)and 71 with hashimoto thyroiditis(HT),since 2000 to 2005. 68 cases had been diagnosed asHashimoto's thyroiditis. 10 cases had been diagnosed as nodulargoiter .5cases had been diagnosed as hyperthyroidism .10 cases withnodulars had been doubted about thyroid cancer .4 cases had beendiagnosed as thyroid cancer . Pathology approve that there are 2casescombined with papillary thyroid carcinoma ,2cases combined with Bcell lymph tumour ,14cases combined with nodular goiter.53caseshave been proved Hashimoto's thyroiditis (HT) Among the 29cases with subacute thyroiditis there are 5 cases combined withnodular goiter ,1 case combined with papillary thyroid carcinoma .Analyse indications for opration of the diseases ,and the causes ofmisdiagnosis and.bring forward treatment of these diseases.Conclusion â‘ attach importance to clinical representation,inorder to avoid unnecessary surgery treatment .â‘¡enteric-coatedaspirin tablets combined with thyroxin in treatment of subacutethyroiditis can acquire ideal therapeutic effectiveness.â‘¢ If theinternal medicine can not acquire satisfied result in treatment ofHashimoto's thyroiditis (HT), surgical treatment can be considered.Surgical treatment not only can discover coincident diseases but alsocan diagnose and treat the diseases which been found.â‘£ The patientswith Hashimoto's thyroiditis who have accepted near-totallobectomy and thyroxin substitute treatment can acquire idealtherapeutic effectiveness. |
