Tumors of the lateral and third ventricles are cradled on all sides by vital vascular and eloquent neural structures. Microsurgical resection, which always requires attentive planning, plays a critical role in the contemporary management of these lesions. This article provides an overview of the open microsurgical approaches to the region highlighting key clinical perspectives.Electronic supplementary materialThe online version of this article (doi:10.1007/s11060-016-2126-9) contains supplementary material, which is available to authorized users.

We experienced an ossified subdural hematoma (OSDH), which is an extremely rare form of chronic subdural hematoma (SDH), in the dominant hemisphere of a 35-year-old woman. She presented to our outpatient clinic with a complaint of a headache; she had previously experienced a head injury while she was pregnant. We performed surgery with extreme caution because the lesion was attached to the surrounding tissue. Since an OSDH is an extremely rare form of chronic SDH, neurosurgeons might not experienced them during their daily practice. Additionally, head injuries received during pregnancy should be taken seriously, and after delivery, the patient should undergo cranial computed tomography, even if she is asymptomatic.

BackgroundThe purpose of this study was to present the clinical results of our retrospective series of carpal tunnel release (CTR) operations. For these operations we used a unique type of incision, for the first time, for treatment of carpal tunnel syndrome (CTS) consisting of a 1-cm semi-vertical (SV) incision made into the wrist crease for macroscopic open CTR.Material/MethodsThis retrospective study included 114 patients (101 females and 13 males) with CTR who were operated upon in our neurosurgery clinic between December 2010 and June 2015. Patient ages ranged from 35 to 83 years (mean 55.05±12.04 years). In total, 127 hands (73 right and 54 left) were operated upon using the SV skin incision technique. After an average follow-up of 18 months (ranging from 6 to 30 months), clinical and electrophysiological (EP) evaluations were performed.ResultsA review of the English language literature published since 1957, when Phalen first popularised the diagnosis and treatment of this disease, determined that no previous reports of the mini-open incision technique as described in our study have been published. In our retrospective patient case review, we found that after operations using the SV incision technique, statistically significant differences were detected in electromyography (EMG) improvements (p<0.01). In addition, patients who showed improvement in EMG studies (n=90) were satisfied with the result of their surgery.ConclusionsOur study demonstrated that 1-cm skin SV incision was a cosmetically satisfying, fast, and safe approach to CTR that was not only clinically effective but also electrophysiologically effective.

IntroductionAtherosclerosis might diminish the nutrient supply to intervertebral discs (IVD), leading to disc herniation. Therefore, there is interest in determining the possible association between the blood lipid profile and lumbar disc herniation (LDH). We aimed to evaluate the association between blood lipids and LDH in a homogeneous group of patients, controlling for age- and sex-specific effects.Material and methodsThis is a case-control study which consisted of 100 individuals (mean age: 41.25 ±9.09; 50 men and 50 women), classified into two groups, as follows. Group I (G-I) consisted of 50 patients who underwent surgery for symptomatic LDH, while group II (G-II) consisted of 50 patients with nonspecific complaints of a headache, but with no previous history of back and/or leg pain, recruited among patients admitted to the outpatient clinic at the time of the study, and whose age and sex were matched to the study group. Total cholesterol (TC), triglyceride (TG), low-density lipoprotein cholesterol (LDL-C), high-density lipoprotein cholesterol (HDL-C), fasting blood glucose, and hemoglobin A1c levels were measured. The TC/HDL-C ratio was calculated. Blood pressure, waist circumference, body mass index, and the history of smoking were included in the analysis.ResultsThe mean values of the TC, TG, LDL-C, HDL-C levels and TC/HDL-C ratio were 198.38, 132.76, 131.9, 40.38 mg/dl and 5.09, respectively. No statistically significant relationship between the blood lipid profile and LDH was identified in this population.ConclusionsBlood lipid levels in this young adult Turkish population did not predict LDH, and may not be a leading cause of IVD ischemia and IVD degeneration.
