- The combination of obstructive sleep apnea syndrome and vascular malformation within the head and neck region is a rare condition, and interestingly, only a few cases have recently been published. Propagation of the vascular mass to the larynx and pharynx can cause breathing and swallowing difficulties. Due to these sypmtoms, examination and initiation of appropriate therapy for such patients are indeed challenging. We reviewed the literature available and present our case of a 64 year old woman emphasizing the complaints of sleep apnea syndrome and vascular malformation of the face and neck region. Polygraphic examination detected severe obstructive sleep apnea syndrome. The MR examination of the neck revealed extensive vascular mass narrowing the pharyngo-laryngeal region, thereby causing temporal bone destruction on the right side with intracranial propagation. ENT examination demonstrated significant narrowing of the pharyngeal lumen and the laryngeal aditus caused by multiple hemangiomas. CPAP titration showed the minimalization of the apnea-hypopnea index on the effective pressure level. Regular CPAP usage resulted in diminishing a majority of the patient's complaints. Our examination clearly demonstrates, obstructive sleep apnea syndrome coupled with significantly obstructing vascular malformation in the head and neck region can be effectively treated safely with a CPAP device, if surgical therapy is not possible. We summarized our findings and the data available in the literature to set up recommendations for the appropriate examination and therapy (including mask fit, etc.) of vascular malformations and hemangiomas causing pharyngolaryngeal obstruction.

- Background and purpose: Deep brain stimulation (DBS) involves placing electrodes within specific deep brain nuclei. For movement disorders the most common indications are tremors, Parkinsons disease and dystonias. Surgeons mostly employ MR imaging for preoperative target selection. MR field geometrical distortion may contribute to target-selection error in the MR scan which can contribute to error in electrode placement.Methods: In this paper we compared the STN target planning coordinates in six parkinsonian DBS patients. Each patient underwent target planning in 1T and 3T MRI. We statistically compared and analysed the target-, and the fiducial coordinates in two different magnetic fileds.Results: The target coordinates showed no significant differences (Mann-Whitney test, p > 0.05), however we found significant difference in fiducial coordinates (p < 0.01), in 3T MRI it was more pronounced (mean ± SD: 0.8 ± 0.3 mm) comparing to 1T (mean ± SD: 0.4 ± 0.2 mm).Conclusion: Preliminary results showed no significant differences in planning of target coordinates comparing 1T to 3T magnetic fields.

- Background: Dyskinesia is among the most troublesome symptoms of advanced Parkinson's disease (PD). The recently developed Unified Dyskinesia Rating Scale (UDysRS) can simultaneously measure several subjective and objective aspects of dyskinesia, irrespective of the other motor symptoms of PD. Despite the advantages of deep brain stimulation (DBS), previous studies on DBS have not used the UDysRS yet.Methods: In this prospective study, 71 consecutive patients undergoing DBS implantation were enrolled. Patients were examined twice: 1 week prior to the DBS implantation (baseline) and 12 months postoperatively. The severity of PD-related symptoms was assessed by the Movement Disorders Society Unified PD Rating Scale (MDS-UPDRS). The presence and severity of dyskinesia were specifically measured by the UDysRS and patient diaries.Results: At baseline, all 71 patients had dyskinesia, but 1 year after DBS implantation, 25 patients were dyskinesia-free, and an additional 19 had only mild dyskinesia. The total score on the UDysRS decreased from 38.0 ± 17.8 to 10.8 ± 13.0 (p < 0.001). Besides this, all parts of the UDysRS showed significant improvement after STN DBS treatment, and the magnitude of these changes had a large effect size. The total score of MDS-UPDRS improved from 76.5 ± 24.3 to 60.4 ± 21.4 points (p < 0.001).Conclusions: Based on our results, UDysRS can reliably detect improvements in dyskinesia after DBS implantation.

- Purpose: This review summarizes protein biomarkers in mild and severe traumatic brain injury in adults and children and presents a strategy for conducting rationally designed clinical studies on biomarkers in head trauma.Methods: We performed an electronic search of the National Library of Medicine's MEDLINE and Biomedical Library of University of Pennsylvania database in March 2008 using a search heading of traumatic head injury and protein biomarkers. The search was focused especially on protein degradation products (spectrin breakdown product, c-tau, amyloid-beta(1-42)) in the last 10 years, but recent data on "classical" markers (S-100B, neuron-specific enolase, etc.) were also examined.Results: We identified 85 articles focusing on clinical use of biomarkers; 58 articles were prospective cohort studies with injury and/or outcome assessment.Conclusions: We conclude that only S-100B in severe traumatic brain injury has consistently demonstrated the ability to predict injury and outcome in adults. The number of studies with protein degradation products is insufficient especially in the pediatric care. Cohort studies with well-defined end points and further neuroproteomic search for biomarkers in mild injury should be triggered. After critically reviewing the study designs, we found that large homogenous patient populations, consistent injury, and outcome measures prospectively determined cutoff values, and a combined use of different predictors should be considered in future studies.

- Myasthenia gravis (MG) is a sporadic autoimmune disorder affecting neuromuscular transmission. Very rarely autoimmune myasthenia gravis may be inherited within a family. We present here the genetic analysis of a Hungarian family where nine members from two generations are affected by myasthenia gravis. Genetic characterisation of this unique Hungarian family using linkage analysis and mutation screening excludes the involvement of defined candidate gene loci. These findings point to familial MG as a separate genetic entity. Identification of the underlying genetic defect in this family may greatly enhance our understanding of the pathogenesis of myasthenia gravis.

- Traumatic brain injury is the leading cause of mortality in Hungary in the population under 40 years of age. In Western societies, like the United Sates, traumatic brain injury represents an extreme social-economic burden, expected to become the third leading cause of mortality until 2020. Despite its' epidemiological significance, experimental therapeutic modalities developed in the last few decades did not prove efficient in the clinical care of severe traumatic brain injury. The reason for such a lack of success in terms of translating experimental results to clinical treatment at least partially could be explained by the paucity and the low sensitivity and specificity of clinical parameters endowing us to monitor the efficacy of the therapy. The drive for finding clinical parameters and monitoring tools that enable us to monitor treatment efficacy as well as outcome focused recent attention on biomarkers (and) surrogate markers that are based on rational pathological processes associated with/operant in traumatic brain injury. This review summarizes those biomarkers that could purportedly be used to monitor the treatment of the severely head injured while also providing information on salvageability facilitating the conduction of more rationally designed clinical studies.
