Abstract
Mason type III fractures of the radial head are treated by open reduction and internal fixation, resection or prosthetic joint replacement. When internal fixation is performed, fixation of the radial head to the shaft is difficult and implant-related complications are common. Furthermore, problems of devascularisation of the radial head can result from fixation of the plate to the radial neck. In a small retrospective study, the treatment of Mason type III fractures with fixation of the radial neck in 13 cases (group 2) was compared with 12 cases where no fixation was performed (group 1). The mean clinical and radiological follow-up was four years (1 to 9). The Broberg-Morrey index showed excellent results in both groups. Degenerative radiological changes were seen more frequently in group 2, and removal of the implant was necessary in seven of 13 cases. Post-operative evaluation of these two different techniques revealed similar ranges of movement and functional scores. We propose that anatomical reconstruction of the radial head without metalwork fixation to the neck is preferable, and the outcome is the same as that achieved with the conventional technique. In addition degenerative changes of the elbow joint may develop less frequently, and implant removal is not necessary.

Abstract
Studies with resVida(®) (a high purity trans-resveratrol) show that trans-resveratrol is a substance of low oral toxicity. An acceptable daily intake (ADI) in food of 450 mg/day has been defined, a level well beyond natural dietary intake of trans-resveratrol. The ADI was based on no-observed-adverse-effect-levels (NOAELs) of 750 mg/kg bw/day in 13-week developmental toxicity studies by the dietary route and a standard safety margin of 100. In studies by gavage, the kidney and bladder are target organs at very high dosages (2,000-3,000 mg/kg bw/day). Six-month studies in rat and rabbit models show no significant increase in toxicity in comparison to 4-week studies. Lower quoted NOAELs in gavage studies (ca. 300 mg/kg bw/day) potentially reflect more rapid bioavailability, but different dosage regimes complicate comparisons. Short-term studies show no genotoxicity in vivo. A 6-month mouse carcinogenicity model showed no increase in tumors. Clinical data support an ADI of at least 450 mg/day, and kinetic data from the DSM 13-week toxicity study also support the expectation of no increase in toxicity with longer term intake.

Abstract
Mucopolysaccharidosis type II (MPS II; Hunter syndrome) is an X-linked, recessive, lysosomal storage disorder caused by deficiency of iduronate-2-sulfatase. It has multisystemic involvement, with manifestations in the brain, upper respiratory tract, heart, abdomen, joints and bones. Bone involvement leads to decreased growth velocity and short stature in nearly all patients. A therapeutic option for patients with MPS II is enzyme replacement therapy (ERT) with idursulfase (Elaprase®). We compared annual growth rates before and during ERT in 18 patients from Mainz, Germany, and Manchester, UK. Group 1 included nine patients who started ERT before 10 years of age; group 2 contained nine patients aged more than 10 years at the start of ERT. All patients had received weekly or biweekly ERT or placebo for 1 year, followed by ERT for more than 3 years. For patients in group 1, the mean (± SD) height increase was 14.6 ± 5.5 cm during 3 years of ERT. Only one patient in this group (who was below the 3rd percentile when starting ERT) deviated from the normal growth curve over this time. Patients in group 2 had a mean height increase of 8.1 ± 1.7 cm after 3 years of ERT compared with an increase of 1 cm in the year before ERT. ERT seems to have a positive influence on growth in patients with MPS II. Most benefit is seen in patients beginning ERT before the age of 10 years. This supports the recommendation that ERT should be started as early as possible in patients with MPS II.

Abstract
306 Background: Pharmacokinetic study in patients with gastrointestinal stromal tumors (GISTs) suggested that plasma concentrations of imatinib decrease following long-term exposure. We therefore measured changes in imatinib plasma trough levels (Cmin) after long-term exposure. Methods: Between November 2009 and May 2010, follow-up (FU) imatinib Cmin was measured in 65 patients who received the same dose of imatinib for at least 9 months after a previous baseline (BL) measurement. Total 244 blood samples were obtained (127 at BL and 117 at FU) and plasma level was measured by liquid chromatography-tandem mass spectrometry. Results: Median patient age was 54 years (range, 28–76 years) and 42 (64.6%) patients were male. Sixty-one (93.8%) patients were treated with 400 mg/day imatinib and 4 (6.2%) with 300 mg/day. The median interval from initiation of imatinib to BL test was 6.4 months (range, 0.5–66.6 months), and the median interval between BL and FU test was 13.1 months (range, 9.6–18.4 months). The mean ± standard deviation imatinib Cmin was significantly higher at FU than at BL (1442 ± 693 ng/mL vs 1221 ± 624 ng/mL, p<0.001). The mean inter- and intra-subject variabilities were 49.2% and 25.5%, respectively, at BL, and 44.2% and 20.4%, respectively, at FU. Multivariate analysis showed a significant correlation between the ratio of FU to BL imatinib Cmin and that of albumin (r=-0.397, p=0.001). In per-sample analysis, imatinib Cmin was significantly correlated with age, hemoglobin, albumin, creatinine clearance, previous major gastrectomy and time between initiation of imatinib and plasma level tests. Conclusions: Steady-state imatinib Cmin did not decrease but remained stable in most GIST patients during long-term treatment. Changes in imatinib Cmin were associated with changes in albumin concentration. Monitoring of imatinib Cmin only for concerns about time-dependent decreases in imatinib exposure is not necessary.

Abstract
We present a multichannel coincidence-counting module for use in quantum optics experiments. The circuit takes up to four transistor-transistor logic pulse inputs and counts either twofold, threefold, or fourfold coincidences, within a user-selected coincidence-time window as short as 12 ns. The module can accurately count eight sets of multichannel coincidences, for input rates of up to 84 MHz. Due to their low cost and small size, multiple modules can easily be combined to count arbitrary M-order coincidences among N inputs.

Abstract
INTRODUCTION After dorsal stabilisation of vertebral fractures by an internal fixateur the postoperative computed tomography is a standard procedure to control the positions of the pedicle screws, the success of the reposition, the clearance of the spinal canal and to plane an additive secondary ventral stabilisation. An intraoperative scan with a 3D image intensifier may clarify these questions directly after the implantation with the possibility of an immediate correction of the implants. The aim of this study was to find out the optimal point of time to perform an intraoperative 3D scan and if a postoperative computed tomography is dispensable. PATIENTS AND METHODS Intraoperative 3D scans were carried out on 33 patients with thoracolumbar spine fractures (T11-L5) after bi-segmental fixateur interne montage (Group 1). A matched pair group of 33 patients (Group 2) with a 3D scan after implantation of pedicle screws was built. A postoperative computed tomography of the instrumented spinal section was done in all patients. The following measurements were done in sagittal and axial reconstruction planes and were compared: classification of screw positions, maximal axial diameter of pedicles, cortical perforation of the screws. Additionally in Group 1 the distance between the upper and lower end plates of the injured section, the height of posterior vertebral body wall, the dislocation of the posterior wall and the minimal diameter of the spinal canal were measured. RESULTS The intraoperative scoring of pedicle screws positions and the measurement of pedicle width showed in both groups a significant accordance with the computed tomography determinations. The measurements "posterior wall dislocation" and "diameter of spinal canal" were only possible in 24 3D scans and showed a significant difference compared with the CT data. The picture quality in Group 2 was scored significantly better than for Group 1 with the complete assembly of the fixateur. CONCLUSION The ideal point of time for an intraoperative 3D imaging with the present intensifier generation is directly after pedicle screw insertion. The reliable determination of the spinal canal diameter, of posterior wall fragments and of the exact fracture morphology is only possible by postoperative computed tomography.

Abstract
Fabry disease is an X-linked inherited condition due to the absence or reduction of alpha-galactosidase activity in lysosomes, that results in accumulation of globotriaosylceramide (Gb3) and related neutral glycosphingolipids. Manifestations of Fabry disease include serious and progressive impairment of renal and cardiac function. In addition, patients experience pain, gastrointestinal disturbance, transient ischaemic attacks and strokes. Additional effects on the skin, eyes, ears, lungs and bones are often seen. The first symptoms of classic Fabry disease usually appear in childhood. Despite being X-linked, females can suffer the same severity of symptoms as males, and life expectancy is reduced in both females and males. Enzyme replacement therapy (ERT) can stabilize the progression of the disease. The rarity of the classic form of Fabry disease, however, means that there is a need to improve the knowledge and understanding that the majority of physicians have concerning Fabry disease, in order to avoid misdiagnosis and/or delayed diagnosis. This review aims to raise awareness of the signs and symptoms of Fabry disease; to provide a general diagnostic algorithm and to give an overview of the effects of ERT and concomitant treatments. We highlight a need to develop comprehensive international guidelines to optimize ERT and adjunctive therapy in patients with Fabry disease, including females and children.

Abstract
We dissected 20 cadaver hips in order to investigate the anatomy and excursion of the trochanteric muscles in relation to the posterior approach for total hip replacement. String models of each muscle were created and their excursion measured while the femur was moved between its anatomical position and the dislocated position. The position of the hip was determined by computer navigation. In contrast to previous studies which showed a separate insertion of piriformis and obturator internus, our findings indicated that piriformis inserted onto the superior and anterior margins of the greater trochanter through a conjoint tendon with obturator internus, and had connections to gluteus medius posteriorly. Division of these connections allowed lateral mobilisation of gluteus medius with minimal retraction. Analysis of the excursion of these muscles revealed that positioning the thigh for preparation of the femur through this approach elongated piriformis to a maximum of 182%, obturator internus to 185% and obturator externus to 220% of their resting lengths, which are above the thresholds for rupture of these muscles. Our findings suggested that gluteus medius may be protected from overstretching by release of its connection with the conjoint tendon. In addition, failure to detach piriformis or the obturators during a posterior approach for total hip replacement could potentially produce damage to these muscles because of over-stretching, obturator externus being the most vulnerable.

Abstract
We report on the generation of impulsive terahertz (THz) radiation with 36 kV/cm vacuum electric field (1.5 mW average thermal power) at 250 kHz repetition rate and a high NIR-to-THz conversion efficiency of 2 x 10(-3). This is achieved by photoexciting biased large-area photoconductive emitter with NIR fs pulses of microJ pulse energy. We demonstrate focussing of the THz beam by tailoring the pulse front of the exciting laser beam without any focussing element for the THz beam. A high dynamic range of 10(4) signal-to-noise is obtained with an amplifier based system.

Abstract
Laser emission over a broad range of frequencies from 2.8 to 4.1 THz is reported for a two-quantum well, photon-phonon cascade structure. Maximum operating temperatures of 125 K are reported, with optical peak powers in eccess of 30 mW from a double-metal ridge waveguide. The broadband nature of the gain curve is identified as due to coherent coupling of the injector and upper lasing states. Internal quantum efficiencies reaching 43 % are evaluated at 10 K.The laser operates in both polarities, showing laser action in reverse bias up to a temperature of 90 K. Simulations based on a full treatment of the structure with density matrix formalism are also presented and discussed.

Abstract
Lysosomal storage diseases represent a group of about 50 genetic disorders. The deficiencies of lysosomal and non-lysosomal proteins cause an accumulation of compounds which are normally degraded within the lysosome. There are currently no therapeutic options to cure patients suffering from a lysosomal storage disease. Due to their progressive nature there is considerable morbidity and mortality. Thus, an early treatment to maintain major systemic functions is of utmost importance. While so far only symptomatic therapies are in use, the newly available enzyme replacement therapies offer a real causal approach for selected storage diseases. Many of these disorders are characterised by pathognomonic eye findings. Therefore, the ophthalmological examination provides the opportunity for an early and non-invasive diagnosis and a chance to initiate early treatment. This review is intended to give a survey of the most common lysosomal storage diseases, particularly with regard to ophthalmological changes as well as illustrate new therapeutic options.

Abstract
The photo-Dember effect is a source of impulsive THz emission following femtosecond pulsed optical excitation. This emission results from the ultrafast spatial separation of electron-hole pairs in strong carrier gradients due to their different diffusion coefficients. The associated time dependent polarization is oriented perpendicular to the excited surface which is inaptly for efficient out coupling of THz radiation. We propose a scheme for generating strong carrier gradients parallel to the excited surface. The resulting photo-Dember currents are oriented in the same direction and emit THz radiation into the favorable direction perpendicular to the surface. This effect is demonstrated for GaAs and In(0.53)Ga(0.47)As. Surprisingly the photo-Dember THz emitters provide higher bandwidth than photoconductive emitters. Multiplexing of phase coherent photo-Dember currents by periodically tailoring the photoexcited spatial carrier distribution gives rise to a strongly enhanced THz emission, which reaches electric field amplitudes comparable to a high-efficiency externally biased photoconductive emitter.

Abstract
GM1 gangliosidosis manifests with progressive psychomotor deterioration and dysostosis of infantile, juvenile, or adult onset, caused by alterations in the structural gene coding for lysosomal acid beta-galactosidase (GLB1). In addition, allelic variants of this gene can result in Morquio B disease (MBD), a phenotype with dysostosis multiplex and entire lack of neurologic involvement. More than 100 sequence alterations in the GLB1 gene have been identified so far, but only few could be proven to be predictive for one of the GM1 gangliosidosis subtypes or MBD. We performed genotype analyses in 16 GM1 gangliosidosis patients of all phenotypes and detected 28 different genetic lesions. Among these, p.I55FfsX16, p.W65X, p.F107L, p.H112P, p.C127Y, p.W161X, p.I181K, p.C230R, p.W273X, p.R299VfsX5, p.A301V, p.F357L, p.K359KfsX23, p.L389P, p.D448V, p.D448GfsX8, and the intronic mutation IVS6-8A>G have not been published so far. Due to their occurrence in homozygous patients, four mutations could be correlated to a distinct GM1 gangliosidosis phenotype. Furthermore, the missense mutations from heteroallelic patients and three artificial nonsense mutations were characterized by overexpression in COS-1 cells, and the subcellular localization of the mutant proteins in fibroblasts was assessed. The phenotype specificity of 10 alleles can be proposed on the basis of our results and previous data.

Abstract
BACKGROUND We analysed 5-year treatment with agalsidase alfa enzyme replacement therapy in patients with Fabry's disease who were enrolled in the Fabry Outcome Survey observational database (FOS). METHODS Baseline and 5-year data were available for up to 181 adults (126 men) in FOS. Serial data for cardiac mass and function, renal function, pain, and quality of life were assessed. Safety and sensitivity analyses were done in patients with baseline and at least one relevant follow-up measurement during the 5 years (n=555 and n=475, respectively). FINDINGS In patients with baseline cardiac hypertrophy, treatment resulted in a sustained reduction in left ventricular mass (LVM) index after 5 years (from 71.4 [SD 22.5] g/m(2.7) to 64.1 [18.7] g/m(2.7), p=0.0111) and a significant increase in midwall fractional shortening (MFS) from 14.3% (2.3) to 16.0% (3.8) after 3 years (p=0.02). In patients without baseline hypertrophy, LVM index and MFS remained stable. Mean yearly fall in estimated glomerular filtration rate versus baseline after 5 years of enzyme replacement therapy was -3.17 mL/min per 1.73 m(2) for men and -0.89 mL/min per 1.73 m(2) for women. Average pain, measured by Brief Pain Inventory score, improved significantly, from 3.7 (2.3) at baseline to 2.5 (2.4) after 5 years (p=0.0023). Quality of life, measured by deviation scores from normal EuroQol values, improved significantly, from -0.24 (0.3) at baseline to -0.17 (0.3) after 5 years (p=0.0483). Findings were confirmed by sensitivity analysis. No unexpected safety concerns were identified. INTERPRETATION By comparison with historical natural history data for patients with Fabry's disease who were not treated with enzyme replacement therapy, long-term treatment with agalsidase alfa leads to substantial and sustained clinical benefits.

Abstract
Hunter syndrome is a rare, X-linked disorder caused by a deficiency of the lysosomal enzyme iduronate-2-sulfatase. In the absence of sufficient enzyme activity, glycosaminoglycans accumulate in the lysosomes of many tissues and organs and contribute to the multisystem, progressive pathologies seen in Hunter syndrome. The nervous, cardiovascular, respiratory, and musculoskeletal systems can be involved in individuals with Hunter syndrome. Although the management of some clinical problems associated with the disease may seem routine, the management is typically complex and requires the physician to be aware of the special issues surrounding the patient with Hunter syndrome, and a multidisciplinary approach should be taken. Subspecialties such as otorhinolaryngology, neurosurgery, orthopedics, cardiology, anesthesiology, pulmonology, and neurodevelopment will all have a role in management, as will specialty areas such as physiotherapy, audiology, and others. The important management topics are discussed in this review, and the use of enzyme-replacement therapy with recombinant human iduronate-2-sulfatase as a specific treatment for Hunter syndrome is presented.

Abstract
OBJECTIVES To study the three-dimensional (3D) T1 patterns in different types of femoroacetabular impingement (FAI) by utilizing delayed gadolinium-enhanced magnetic resonance imaging (MRI) of cartilage (dGEMRIC) and subsequent 3D T1 mapping. We used standard grading of OA by Tonnis grade on standard radiographs and morphological grading of cartilage in MRI for comparative analysis. METHODS dGEMRIC was obtained from ten asymptomatic young-adult volunteers and 26 symptomatic FAI patients. MRI included the routine hip protocol and a dual-flip angle (FA) 3D gradient echo (GRE) sequence utilizing inline T1 measurement. Cartilage was morphologically classified from the radial images based on the extent of degeneration as: no degeneration, degeneration zone measuring <0.75 cm from the rim, >0.75 cm, or total loss. T1 findings were evaluated and correlated. RESULTS All FAI types revealed remarkably lower T1 mean values in comparison to asymptomatic volunteers in all regions of interest. Distribution of the T1 dGEMRIC values was in accordance with the specific FAI damage pattern. In cam-types (n=6) there was a significant drop (P<0.05) of T1 in the anterior to superior location. In pincer-types (n=7), there was a generalized circumferential decrease noted. High inter-observer (intra-observer) reliability was noted for T1 assessment using intra-class correlation (ICC):intra-class coefficient=0.89 (0.95). CONCLUSIONS We conclude that a pattern of zonal T1 variation does seem to exist that is unique for different sub-groups of FAI. The FA GRE approach to perform 3D T1 mapping has a promising role for further studies of standard MRI and dGEMRIC in the hip joint.

Abstract
Autoantibodies to the synaptic protein amphiphysin play a crucial pathogenic role in paraneoplastic stiff-person syndrome. Impairment of GABAergic inhibition is the presumed pathophysiological mechanism by which these autoantibodies become pathogenic. Here we used calcium imaging on rat embryonic motor neurons to investigate whether antibodies to amphiphysin directly hinder GABAergic signaling. We found that the immunoglobulin G fraction from a patient with stiff-person syndrome, containing high titer antibodies to amphiphysin and inducing stiffness in rats upon passive transfer, reduced GABA-induced calcium influx in embryonic motor neurons. Depletion of the anti-amphiphysin fraction from the patient's IgG by selective affinity chromatography abolished this effect, showing its specificity for amphiphysin. Quantification of the surface expression of the Na(+)/K(+)/2Cl(2-) cotransporter revealed a reduction after incubation with anti-amphiphysin IgG, which is concordant with a lower intracellular chloride concentration and thus impairment of GABA mediated calcium influx. Thus, anti-amphiphysin antibodies exert a direct effect on GABA signaling, which is likely to contribute to the pathogenesis of SPS.

Abstract
Broadband horn antennae are presented that efficiently couple terahertz radiation between sub-wavelength metal-metal waveguides and free space. Sub-picosecond terahertz pulses were coupled into and out from sub-wavelength parallel-plate waveguides by using the horn antennae in a terahertz time-domain spectrometer. Monolithic antennae were fabricated at the facets of metal-metal terahertz quantum cascade lasers, and laser action was observed for devices emitting at 1.4 THz, 2.3 THz and 3.2 THz. A good far-field laser radiation pattern (FWHM less than 11 degrees) is obtained as a result of the significant expansion of the optical mode by the antenna.

Abstract
Dislocations and fracture-dislocations of the elbow joint result in typical injury patterns of variable joint instability. A systematic and early in-depth analysis of the injury components offers the approach to the options of therapy and the evaluation of the risk potential of the individual lesion. Standardized diagnostic algorithms help to avoid an inadequate assessment of the extent of injury. With regard to the choice of therapy finding a balance between the concentric reduction of the elbow joint, stability and an early regain of motion provides the key to a good functional outcome. A great number of simple elbow dislocations have a good prognosis and can be managed with early motion due to the inherent joint stability after closed reduction. In contrast, the more rare osteo-ligamentous combination injuries have a poor prognosis if the corresponding injury components are not adequately recognized and addressed by a mostly technically demanding surgical treatment to avoid the otherwise impending typical complications. A standardized surgical algorithm may provide the basis to achieve a satisfactory functional result in this challenging clinical entity of elbow trauma.

Abstract
The principle of the articulated external fixator following elbow dislocation and fracture-dislocations of the elbow joint is a helpful adjunct to the surgical armamentarium. It protects a difficult reconstruction of the joint surfaces, the capsule and the ligaments against potentially harmful forces while allowing passive and active motion to prevent arthrofibrosis due to long-term immobilization of the elbow joint. The articulated external fixator further represents a salvage procedure for delayed reconstructions and distraction arthrolysis, as well. A precise surgical technique is a prerequisite for the success of the procedure.

Abstract
Mucopolysaccharidosis type II (MPS II or Hunter syndrome) is a progressive, multisystemic disease caused by a deficiency of iduronate-2-sulfatase. Patients with the severe form of the disease have cognitive impairment and typically die in the second decade of life. Patients with the less severe form do not experience significant cognitive involvement and may survive until the fifth or sixth decade of life. We studied the relationship of both severity of MPS II and the time period in which patients died with age at death in 129 patients for whom data were entered retrospectively into HOS (Hunter Outcome Survey), the only large-scale, multinational observational study of patients with MPS II. Median age at death was significantly lower in patients with cognitive involvement compared with those without cognitive involvement (11.7 versus 14.1 years; p = 0.024). These data indicate that cognitive involvement is indicative of more severe disease and lower life expectancy in patients with MPS II. Median age at death was significantly lower in patients who died in or before 1985 compared with those who died after 1985 (11.3 versus 14.1 years; p alpha 0.001). The difference in age at death between patients dying in or before, relative to after, the selected cut-off date of 1985 may reflect improvements in patient identification, care and management over the past two decades. Data from patients who died after 1985 could serve as a control in analyses of the effects of enzyme replacement therapy with idursulfase on mortality in patients with MPS II.

Abstract
Background Sitting in new chairs or sofas has elicited dermatitis in numerous patients in Finland and in the U.K. since autumn 2006. The cause of the dermatitis seemed to be an allergen in the furniture materials. Objectives To determine the cause of the dermatitis in patients with furniture-related dermatitis. Methods Altogether 42 patients with furniture-related dermatitis were studied. First, 14 Finnish patients were patch tested with the standardized series and with the chair textile material. A thin-layer chromatogram (TLC) strip and an extract made from the same textile material were tested in seven Finnish patients. The test positive spot of the TLC and the content of a sachet found inside a sofa in the U.K. were analysed by using gas chromatography-mass spectrometry. All chemicals analysed were patch tested in 37 patients. Results A positive patch test reaction to the chair textile and to its extract was seen in all patients tested, one-third of whom had concurrent reactions to acrylates. Positive reactions to the same spot of the TLC strip were seen in five of seven patients and dimethyl fumarate was analysed from the spot as well as from the sachet contents. Dimethyl fumarate (0.01%) elicited positive reactions in all the patients. The other chemicals analysed did not elicit positive reactions, but one patient in the U.K. had a positive reaction to tributyl phosphate. Conclusions Sensitization to dimethyl fumarate was seen in all the patients with furniture-related dermatitis. Concurrent sensitization or cross-reactions were common among the sensitized patients.

Abstract
BACKGROUND Mucopolysaccharidosis VI (MPS VI) is a very rare, chronically debilitating lysosomal storage disorder that develops in people with an enzyme deficiency. Clinical characteristics and progression rates vary widely between patients. The recent introduction of enzyme replacement therapy (ERT) has improved considerably the lives of patients with MPS VI, at an annual cost of treatment between euro 150,000 and euro 450,000 per patient. SCOPE This Commentary article addresses the controversial topic of granting reimbursement for expensive treatment options for orphan diseases, such as MPS VI. The discussion reflects clinical, economic and ethical aspects and incorporates insights from the relevant literature (based on a Medline search to September 2008) on MPS VI, efficacy of ERT, orphan drugs, and the economics and ethics of health-care prioritisation. FINDINGS Although ERT for MPS VI received marketing authorisation in the European Union in January 2006, patients' access to this therapy varies geographically due to differences between national reimbursement schemes for orphan drugs. Some inclusion and exclusion criteria for treatment of MPS VI patients with ERT appear arbitrary and may contribute to the exclusion from treatment of patients who could benefit in the long term. Reimbursement schemes which rely on proof of short-term treatment effectiveness may discriminate against slowly progressive patients, as health gain can often not be confirmed over a short period of time in these patients. Conventional cost-effectiveness analysis remains silent on crucial issues related to budgetary impact, i.e. opportunity cost from a system perspective, and fair access to treatment. CONCLUSIONS To prevent patients from being deprived of effective treatment, it is suggested that inclusion and exclusion criteria for treatment should be primarily based on a careful individual assessment of expected long-term clinical benefits. Once treatment has been agreed to as the correct option on clinical grounds, it is further argued that the conventional cost-effectiveness criterion currently in widespread use does not offer a sufficient basis for rejecting reimbursement of expensive treatments for exceptionally rare disorders, providing that decisions on reimbursement are intended to reflect public preferences.

Abstract
BACKGROUND Neurologic hallmarks of Fabry disease (FD) include small fiber neuropathy as well as cerebral micro- and macroangiopathy with premature stroke. Cranial MRI shows progressive white matter lesions (WML) at an early age, increased signal intensity in the pulvinar, and tortuosity and dilatation of the larger vessels. To unravel the most promising imaging tool for the detection of CNS involvement in FD we compared the diagnostic utility of the different MR imaging findings. METHODS Twenty-five clinically affected patients with FD (age 36.5 +/- 11.0) and 20 age-matched controls were investigated by structural MRI, MR angiography, and diffusion tensor imaging (DTI). Individual WML volumes, global mean diffusivity (MD), and mean cerebral artery diameters were determined. RESULTS Using receiver operating characteristic analyses, enlarged diameters of the following cerebral arteries significantly separated patients with FD from controls: middle cerebral artery: area under curve (AUC) = 0.75, p = 0.005; posterior cerebral artery: AUC = 0.69, p = 0.041; carotid artery: 0.69, p = 0.041; basilar artery: AUC = 0.96, p < 0.0005. A total of 87% of the individuals were correctly classified by basilar artery diameters (sensitivity 95%, specificity 83%). WML volumes and global MD values did not significantly separate patients from controls. CONCLUSIONS With an accuracy of 87%, basilar artery diameters were superior to all other MR measures for separating patients with Fabry disease (FD) from controls. Future studies should adopt basilar artery measurements for early detection and monitoring of brain involvement in FD. Moreover, further investigations should reveal if the dilated vasculopathy in FD could be a screening marker to detect FD in a cohort of other cerebrovascular diseases, especially in cryptogenic stroke.
