Hypothalamic-pituitary-gonadal axis function is necessary for maintaining proper female reproductive cycle. This study aimed to evaluate the ovarian histomorphometric and histoarchitectural changes in neonatal, prepubertal pubertal thymectomized guinea pigs. A total of 30 pigs, sham-operated (n-5) were studied each group. The diameter number follicles among sham operated pigs during estrus phas...

The pathophysiological role of the thymus in myasthenia gravis, and the mechanism of therapeutic effect of thymectomy, are incompletely understood. Nevertheless, thymectomy is a valuable treatment modality in selected patients with generalised myasthenia gravis. There are several types of thymectomy operation, but no one operative approach is clearly superior to the others. Total removal of the...

Thymectomy has been shown to be effective in the treatment of myasthenia gravis. The logical goal of operation is the complete removal of the thymus, but there is no consensus on the selection criteria of patients for surgery and the choice of surgical approach. We retrospectively reviewed 56 patients with myasthenia gravis who had been treated surgically by transsternal radical thymectomy betw...

BACKGROUND The efficacy of thymectomy in patients with non-thymomatous Myasthenia Gravis (MG) is still unclear. Main limitations have been variable outcome definitions, lack of a control group and adjustment for confounding. OBJECTIVE To study the efficacy of thymectomy in achieving remission or minimal manifestation (R/MM) status in patients with non-thymomatous MG. METHODS Patients with g...

Aplastic anemia is a rare complication of thymoma and is extremely infrequent after thymectomy. We present a case of a 60-year-old woman with very severe aplastic anemia appearing sixteen months after thymectomy for a thymoma. She underwent thymectomy for a thymoma in April 2000. Preoperative examination revealed no hematologic abnormality. About sixteen months after the operation, she was read...

The present study was conducted to evaluate the effect of thymectomy during open heart surgery on immunological function of T lymphocytes in the treatment of children with congenital heart disease (CHD). No significant difference was found in the sjTREC level between pre-thymectomy and post- thymectomy in the non-thymectomy group and the small partial resection group (P>0.05) However, the sjTRE...

According to the recommendation of The International Thymic Malignancy Interest Group (ITMIG), surgical resection of anything less than a complete thymectomy is considered inappropriate at this time except in the context of a clinical trial. Therefore, limited thymectomy may be not appropriate for thymoma resection. However, there is little evidence that mandates surgeons perform complete thyme...

Myasthenia gravis (MG) is an autoimmune disorder characterized by autoantibodies against acetylcholine receptors. MG is generally an isolated disorder but may occur concomitantly with other autoimmune diseases. We describe an eighteen-year-old girl with MG who was admitted to our clinic with secondary amenorrhea and diagnosed as autoimmune oophoritis. Since her myasthenic symptoms did not resol...
