LETTER TO THE EDITOR Transient cerebellar mutism in childhood Mehmet Turgut Received: 28 December 2006 / Published online: 24 March 2007 # Springer-Verlag 2007 Dear Editor: I read with interest the article by Huber et al. entitled “Long-term effects of transient cerebellar mutism after cerebellar astrocytoma or medulloblastoma tumor resection in childhood” [1] and wish to congratulate my colleagues on this unique contribution to the literature regarding postoperative cerebellar mutism syndrome. Unfortunately, a few following points crossed my mind while I was reading the article. In addition, I would like to add the following important points to the discussion for the sake of completeness of the information presented: 1. For your readers, actually, it is important to remember that transient cerebellar mutism is not only a postoperative entity, but also a preoperative condition due to various vascular, traumatic, or infectious etiology [2, 3]. 2. Based on my experience and literature data, I completely agree with the authors that it is prudent to provide children who manifest transient cerebellar mutism with speech and language therapy after their recovery from posterior fossa surgery. 3. Lastly, the structure of a scientific contribution is as important as the content proper, which is completely the responsibility of the author(s) of the article.

Dear Editor:I read with interest the article by Huber et al. entitled“Long-term effects of transient cerebellar mutism aftercerebellar astrocytoma or medulloblastoma tumor resectionin childhood” [1] and wish to congratulate my colleagueson this unique contribution to the literature regardingpostoperative cerebellar mutism syndrome. Unfortunately,a few following points crossed my mind while I wasreading the article. In addition, I would like to add thefollowing important points to the discussion for the sake ofcompleteness of the information presented:

1. For your readers, actually, it is important to rememberthat transient cerebellar mutism is not only a postoper-ative entity, but also a preoperative condition due tovarious vascular, traumatic, or infectious etiology [2, 3].

2. Based on my experience and literature data, I com-pletely agree with the authors that it is prudent toprovide children who manifest transient cerebellarmutism with speech and language therapy after theirrecovery from posterior fossa surgery.

3. Lastly, the structure of a scientific contribution is asimportant as the content proper, which is completelythe responsibility of the author(s) of the article.According to the Index Medicus data, the titles of 1

and 11 are incomplete. Moreover, the page numbers inreferences 4 and 10 are not correct. Furthermore,reference 7 [David et al. (1997) Medulloblastoma: isthe 5-year survival rate improving? A review of 80cases from a single institution. J Neurosurg 86:13–21]and reference 16 [Huber-Okrainec et al.
