Presentation
Furthermore, being less painful in the postoperative period, it presents a less pronounced impairment of pulmonary function, and it presents good cosmetic effect. [ncbi.nlm.nih.gov]
Entire Body System
-
High Fever
The patient presented with high fever and agranulocytosis. Complete blood count revealed a white blood cell count of 0.9 109/L (3% neutrophils), a hemoglobin level of 15.8 g/dL, and a platelet count of 308 109/L. [ncbi.nlm.nih.gov]
-
Vietnamese
The clinical characteristics of thymoma and the outcomes of video-assisted thoracoscopic thymectomy in Vietnamese patients are still lacking. [ncbi.nlm.nih.gov]
Respiratoric
-
Sputum
A 67-year old man presented with cough and bloody sputum. Chest computed tomography showed an anterior mediastinal mass with a right hilar nodule. A right upper sleeve lobectomy and a thymectomy were performed via a VATS approach. [ncbi.nlm.nih.gov]
Gastrointestinal
-
Intermittent Dysphagia
We report the case of a 22-year-old female with a 6-year history of MG presented with bilateral ptosis, diplopia, and intermittent dysphagia. She denied shortness of breath, dysarthria, and fatigue. [ncbi.nlm.nih.gov]
Musculoskeletal
-
Migratory Polyarthritis
This case report describes a 50-year-old man who presented with migratory polyarthritis and an anterior mediastinal mass that proved to be a thymoma. [ncbi.nlm.nih.gov]
-
Proximal Muscle Weakness
On examination,she had moderately severe fatigable proximal muscle weakness and ptosis. [ncbi.nlm.nih.gov]
Urogenital
-
Secondary Amenorrhea
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 resolve with anticholinesterase therapy, thymectomy was performed. [ncbi.nlm.nih.gov]
-
Amenorrhea
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 resolve with anticholinesterase therapy, thymectomy was performed. [ncbi.nlm.nih.gov]
Neurologic
-
Neglect
Preoperative anxiety (POA) is common but typically neglected in MG patients. [ncbi.nlm.nih.gov]
Workup
Pre-operative Workup and Preparation Computed tomography – this is almost always obtained pre-operatively if a mediastinal mass is suspected and includes contrast enhancement to evaluate the involvement of the nearby vascular structures. [insidesurgery.com]
You may be required to undergo several diagnostic tests, including: A blood workup EKG CT Scan PET Scan What to Expect Thymectomy is performed under general anesthesia. [northshore.org]
Edrophonium is primarily but rarely used as a diagnostic tool to predict the response to longer-acting cholinesterase inhibitors (see Workup). [43] AChE inhibitors have a wide variability in the effective dose, depending on the severity and current activity [emedicine.medscape.com]
Serum
-
Lymphocytopenia
The lymphocytopenia, low CD4 count, and failed response to pneumococcal vaccination that presented in our patient are consistent with immunodeficiency. [ncbi.nlm.nih.gov]
However, unlike our patient, patients with Good syndrome do not manifest with severe CD4 lymphocytopenia. [jmedicalcasereports.com]
In view of the T-cell lymphocytopenia, an additional analysis was performed to determine whether lower TREC concentration in subjects who underwent thymectomy were due to reductions in T-cell number. [nature.com]
Other ECG Findings
-
Abnormal ECG
Myasthenia gravis is not usually considered in the differential diagnosis of conditions associated with an abnormal ECG. [ncbi.nlm.nih.gov]
Treatment
The effectiveness of extended thymectomy for the treatment of myasthenia gravis is well documented. [ncbi.nlm.nih.gov]
Prognosis
Finally, thymic lymphoid hyperplasia and severe symptoms may negatively affect prognosis of MG following thymectomy. Copyright 2017 Elsevier B.V. All rights reserved. [ncbi.nlm.nih.gov]

They emphasize that the duration of the disease is a better indicator of postresection prognosis than gender or youth, concluding that the operation should be indicated early after the onset of symptoms. [peertechz.com]
Etiology
Abstract Following thorascopic thymectomy performed because of myasthenia gravis, a 25-year-old man was affected by fulminant hepatic failure (FHF) of unknown etiology. [ncbi.nlm.nih.gov]
Knowledge of the pathogenesis of MG has enabled the development of different therapeutic approaches on a symptomatic and etiologic basis. [annalscts.com]
As the disease has a relatively low incidence and different etiologies, the construction of homogeneous groups in enough number is quite difficult. [ojrd.biomedcentral.com]

Epidemiology
[…] compare the morbidity and mortality of three techniques [cervicotomy with upper sternotomy versus sternotomy versus video-assisted thoracic surgery (VATS)/robotic-assisted thoracic surgery (RATS)] from the national database EPITHOR and to analyse French epidemiology [ncbi.nlm.nih.gov]

For ethical and epidemiological reasons and due to the pathogenesis of MG a single-center study design with higher level of evidence seems difficult to achieve. [edoc.hu-berlin.de]
Pathophysiology
Progressive disease seen after thymectomy in this patient has potential implications regarding the pathophysiological characteristics of microscopic polyangiitis and management of patients with this clinical association. [ncbi.nlm.nih.gov]
The pathophysiology is related to the presence of acetylcholine receptors generated in the thymus, which ultimately lead to the symptoms. [scielo.br]
Prevention
To prevent serious complications, we suggest that patients who have undergone both thymectomy and radiation therapy be monitored for immunodeficiency. [ncbi.nlm.nih.gov]
In thymic tumors, thymus removal (thymectomy) can be used to prevent spread of disease. [drdimaio.com]
