In the acute settings of generalized myasthenia gravis (MG) treatment options include plasma exchange (PLEX), intravenous immunoglobulin (IVIG), and pyridostigmines. A thymoma is associated with the disease in up to 20% of cases [1,2].

In cases where a thymoma is detected, surgical treatment to remove the tumor is recommended in certain age groups. At present, there are no clear guidelines regarding the optimal time to perform thymectomy after diagnosis of acute crisis or from the last treatment to thymectomy. Treatment is at the clinician's discretion.

The Oxford-AstraZeneca vaccine ChAdOx1 (AZD1222, Vaxzevria) is playing a crucial role in counteracting the coronavirus disease-2019 (COVID-19) pandemic [1]. Since March 2021, reports of unexpected thrombotic events associated with thrombocytopenia and vaccination have been published [2]. To the best of our knowledge there is only one report about vaccination-associated myasthenia gravis (MG) occurring after a second dose of BNT162b2 (Pfizer-BioNTech)

Background: Thymectomy is a reliable surgical method for treating patients with myasthenia gravis (MG) and benign tumors of the thymus. Despite the advantages of minimally invasive surgical approaches for resection of thymic neoplasms, there are still controversies regarding the superiority of one type of surgery over another.

Objectives: To report the results of our initial Israeli experience with robotic thymectomy in 22 patients with MG and suspected benign thymic tumors.

Methods: We retrospectively analyzed 22 patients (10 men, 12 women) who underwent robotic thymectomy by a left-sided (16) or right-sided approach (6) using the da Vinci robotic system at Assaf Harofeh Medical Center. Seven patients were diagnosed with MG before surgery and 14 had suspected benign thymic neoplasms.

Results: Average operative time was 90 minutes. There were no deaths or intraoperative complications. Postoperative complications occurred in two patients (dyspnea and pleural effusion). Median blood loss was 12.3 cc (range 5–35 cc), median hospital stay 2.9 days (range 2–5 days), and mean weight of resected thymus 32.1 grams. Seven patients had thymic hyperplasia, six a lipothymoma, one a thymic cyst. Seven each had thymomas in different stages and one had a cavernous hemangioma.

Conclusions: Robotic thymectomy is a safe, technically effective surgical method for resection of thymic neoplasms. The advantages of this technique are safety, short hospitalization period, little blood loss, and low complications. We have included this surgical procedure in our thoracic surgery residency program and recommend a learning curve program of 10 to 12 procedures during residency.

Medical screening is not a tangible existent tool in autoimmune disorders as it is in other illnesses. Numerous attempts are made to identify individuals destined to develop an autoimmune disease, including analysis of the genetic background, which along with the immunological profile, may assist in identifying those individuals. If these efforts turn out to be successful they may lead to the possibility of proactive measures that might prevent the emergence of such disorders. This review will summarize the attempts made to pursue autoantibodies specific for the central nervous system as potential predictors of autoimmune neurological disorders.
