This study is designed based on the retrospective analysis of patients treated in the Neurosurgical Department of two major hospitals and review of the literature. The aim of this study is to evaluate the efficacy of surgery and address controversial issues in the treatment of symptomatic lumbar intraspinal synovial cysts. Spinal juxtafacet cysts (synovial and ganglion cysts) are a rare cause of low back and radicular leg pain. Although the relevant reports in the international literature are increasing, the controversy about conservative versus surgical treatment and the need for concomitant fusion still exists. Data from seven patients (age range 58-69 years, mean age 61 years) with low back and radicular leg pain due to a lumbar facet joint cyst were retrospectively analyzed. Demographic data, cyst level, presence of concomitant local pathology, treatment and results of treatment were recorded. A follow-up of at least 6 months (range 6-48 months) was conducted and results were noted. All patients had back pain, while five also experienced unilateral radicular leg pain and one had bilateral leg pain. One patient had neurogenic claudication. MRI identified the cyst and highlighted underlying pathology in all cases. All patients underwent surgical cyst excision. No fusion was performed. Post-operatively, all patients showed a total resolution of symptoms with sustained benefit at final evaluation. Review of the literature revealed a trend towards surgery, as this is correlated to a more favorable outcome compared with conservative treatment. Fusion should be performed on a case-by-case basis only. Surgery is a safe and effective treatment choice in this increasingly appearing ailment. A prospective, randomized trial should clarify issues under debate.

Background and Purpose-To investigate the incidence, pattern, and magnitude of neuroendocrine changes in long-term survivors of aneurysmal subarachnoid hemorrhage (SAH). Methods-Thirty patients (16 women) with a mean age of 50Ϯ13 years underwent endocrine assessment between 12 and 24 months after aneurysmal SAH. SAH severity was graded clinically by the Hunt & Hess scale (median, II) and radiologically by the Fisher classification (median, II). Patients underwent measurement of basal hormone levels and dynamic assessment by the low-dose (1 g) corticotropin stimulation test. Functional outcome was examined concurrently with endocrine testing by the modified Rankin Scale and the Barthel Index. Results-Of the 30 patients tested, 14 patients (47%) showed isolated or combined endocrine abnormalities. These included low insulin-like growth factor 1 levels compatible with growth hormone deficiency in 37%, hypogonadism in 13%, and cortisol hyporesponsiveness to the low-dose corticotropin stimulation test in 10%; thyroid dysfunction in the form of subclinical hypothyroidism was observed in 7% of patients. Median modified Rankin Scale and Barthel Index at the time of endocrine testing were 1 and 100, respectively. There was no correlation between the presence of endocrine dysfunction and SAH severity indices or functional outcome scores. Conclusions-Long-term survivors of aneurysmal SAH frequently exhibit endocrine changes, with growth hormone and gonadal deficiencies predominating. Thus, screening of pituitary function is recommended in patients surviving SAH. The relationship between late hormonal alterations and functional outcome in patients with SAH warrants further study.

Complication rates after DBS surgery remain low, proving that DBS is not only effective but also safe. Certain strategies do exist in order to minimize complications.
