Rothia dentocariosa is a rare cause of endocarditis. It occurs most frequently in patients with prior heart conditions. Although the clinical course is typically subacute, it has a high rate of complications. In particular, the reported incidence of mycotic aneurysms is as high as 25%. Penicillin is the treatment of choice, but additional complications may necessitate prompt surgical intervention. As far as we know, this paper reports the first case of repeated subarachnoid hemorrhages due to R. dentocariosa endocarditis.

The results of this technique compare favorably with posterior stabilization and fusion (posterior lumbar interbody fusion and postero-lateral fusion) reported in the literature. Unlike posterior lumbar interbody fusion, however, it seems that the complication rate due to the approach is much lower, the fusion rate is similar. Grade 2 SPL is the limitation of the technique. The main advantage of the technique is to avoid posterior muscle damage and a quick recovery with no blood loss. Preservation of adjacent level disease can be assessed only after long-term follow-up.

Background: Schwannomatosis is a relatively rare disorder and is related to neurofibromatosis type 2. Although there is clinical overlap between schwannomatosis and neurofibromatosis type 2, these diseases have to be regarded as separate entities due to the genetic origin and course of the disease. Methods: A comprehensive review of the literature was conducted for relevant studies using Pubmed and Cochrane databases to discuss the epidemiology, clinical presentation, diagnostic criteria, pathological and imaging features, treatment and genetics of schwannomatosis. Results: Germline mutations SMARCB1 and LZTRI together with the NF2 gene play a role in the pathophysiology of schwannomatosis. The most common symptom is pain with affection of the spine and peripheral nerves in the majority of patients. High quality contrast enhanced MRI scan is the imaging modality of choice. Treatment is conservative if asymptomatic and surgical if symptomatic. The goal is symptom control with preservation of neurological function. Conclusion: Schwannomatosis is a relatively rare disorder in which the main goal is to preserve neurological function.

The interim outcomes showed significant improvements in mean ODI and VAS scores. The results of these European studies suggest that the DASCOR Device may be a safe and effective less-invasive surgical option for patients with DDD.
