Abstract
Mesenchymal stem cells (MSCs) participate in regenerative osteogenesis by generating bone-forming cells. To examine the proliferative capacity of MSC populations from bone marrow and their relationship to trauma severity (multiple trauma, monofracture, atrophic nonunion), we quantified colony properties of human MSCs in vitro. Serum levels of mediators associated with bone formation were also assessed. Fifty-five individuals were enrolled in this study (13 multiple trauma patients, 15 patients with monofracture, 20 patients with atrophic nonunions, 7 healthy volunteers). The colony forming unit-fibroblast (CFU-F) assay was used to quantify total colony number, mean cell density per colony, and mean colony area. MSC phenotype was established using flow cytometry and osteogenic differentiation. MSCs obtained from multiple-trauma patients yielded the highest reservoir. Significant differences in colony numbers of MSCs in female subjects were found between multiple-trauma patients (mean +/- SD 48 +/- 21 CFU-F/culture) and healthy volunteers (18.7 +/- 3.3 CFU-F/culture, P < 0.05), patients with monotrauma (15 +/- 10 CFU-F/culture, P < 0.05), and patients with atrophic nonunions (6.3 +/- 4.1 CFU-F/culture, P < 0.05). In male participants, significant differences were found between patients with nonunions (14 +/- 14 CFU-F/culture) and healthy volunteers (54 +/- 17 CFU-F/culture, P < 0.05) as well as multiple-trauma patients (59 +/- 25 CFU-F/culture, P < 0.05). The highest proliferative capacity (cell density) was seen in multiple-trauma patients. These data suggest that trauma severity and gender affect the reservoir and proliferation capacity of bone marrow-derived MSCs.

Abstract
Percutaneous vertebroplasty (PVP) is carried out under fluoroscopic control in most centers. The exclusion of implant leakage and the assessment of implant distribution might be difficult to assess based on two-dimensional radiographic projection images only. We evaluated the feasibility of performing a follow-up examination after PVP with rotational acquisitions and volumetric reconstructions in the angio suite. Twenty consecutive patients underwent standard PVP procedures under fluoroscopic control. Immediate postprocedure evaluation of the implant distribution in the angio suite (BV 3000; Philips, The Netherlands) was performed using rotational acquisitions (typical parameters for the image acquisition included a 17-cm field-of-view, 200 acquired images for a total angular range of 180 degrees ). Postprocessing of acquired volumetric datasets included multiplanar reconstruction (MPR), maximum intensity projection (MIP), and volume rendering technique (VRT) images that were displayed as two-dimensional slabs or as entire three-dimensional volumes. Image evaluation included lesion and implant assessment with special attention given to implant leakage. Findings from rotational acquisitions were compared to findings from postinterventional CT. The time to perform and to postprocess the rotational acquisitions was in all cases less then 10 min. Assessment of implant distribution after PVP using rotational image acquisition methods and volumetric reconstructions was possible in all patients. Cement distribution and potential leakage sites were visualized best on MIP images presented as slabs. From a total of 33 detected leakages with CT, 30 could be correctly detected by rotational image acquisition. Rotational image acquisitions and volumetric reconstruction methods provided a fast method to control radiographically the result of PVP in our cases.

High spatial resolution contrast-enhanced MR angiography of the supraaortic arteries using the quadrature body coil at 3.0T: A feasibility study. Eur Radiol 2006; 17:618-25. [PMID: 16944161 DOI: 10.1007/s00330-006-0406-z] [Citation(s) in RCA: 23] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/17/2005] [Revised: 06/02/2006] [Accepted: 07/07/2006] [Indexed: 10/24/2022]
Abstract
To examine whether the the increased signal-to-noise (S/N) available at 3.0T would permit the use of the quadrature body coil for high spatial resolution contrast-enhanced (CE) MR angiography (MRA), and whether the large FOV that was used in our routine 1.5T protocol would also be feasible at 3.0T. In a prospective study, 43 patients and five volunteers were examined on a clinical whole-body 3.0T MR unit (Intera, Philips Medical Systems, Best, The Netherlands) after institutional review board approval and informed consent. Three-dimensional CE MRA (T1 gradient echo-sequence with TR/TE = 5.7/1.93 msec.; acquisition time, 1:54 min.) using randomly segmented central k-space ordering (CENTRA) was acquired with the quadrature body coil, using over a FOV of 350 mm. A high-image matrix of 432x432 yielded a non-zero filled voxel size of 0.81 mm x 0.81 mm x 1.0 mm (0.66 mm(3)). For quantitative analysis, contrast ratios (CR) between vessels (S) and signal in surrounding tissue (ST) were calculated [(S-ST)/(S+ST)]. For qualitative analysis, image quality and presence of artifacts were rated by two radiologists in consensus on a five-point scale (1=excellent to 5=nondiagnostic). Digital subtraction angiography (DSA) served as the standard of reference in patients with vascular disease. In the five volunteers, 1.5T CE MRA using a phased array neurovascular coil was available for intraindividual comparison. 3.0T CE MRA was successfully performed in 48/48 subjects (100%). Mean CR+/- SD were 0.76 (139.30/182.42) and 0.87 (235.18/270.14) at 3.0T and 1.5T respectively . Mean image quality was 3.82+/-0.86. Intraindividual comparison between 1.5T and 3.0T CE MRA in the volunteers revealed no significant difference in image quality (4.2+/-0.74 vs 4.6+/-0.80; p>0.05). Vascular disease was correctly identified in 13/13 patients with DSA correlation. CE MRA of the supraaortic arteries is feasible at 3.0T using a large FOV of 350 mm. The signal gain at 3.0T enables high spatial resolution contrast-enhanced MR angiography by using the built-in quadrature body coil only.

Abstract
OBJECTIVE To assess the rates and perceived effectiveness of actions used to cope with depression and the factors influencing these in an outpatient sample seeking help for depression. METHOD One hundred and seventy-six patients (74 male, 102 female) aged 16-82 years (M = 42, SD = 14.4 years) with a major depressive episode (DSM-IV criteria) were assessed using a number of measures that covered sociodemographics, history of psychiatric illness, actions taken to alleviate depression and their perceived effectiveness. Logistic regression analyses assessed age, gender and illness characteristics associated with the use and perceived effectiveness of strategies adopted to manage depression. RESULTS Medical interventions were used and perceived to be effective in alleviating depressive symptoms by most of the sample, as were self-help and complementary therapies. Sociodemographic and illness-related characteristics had a significant influence, with younger age and having experienced an episode of anxiety disorder found to be the strongest predictors for the use of coping strategies. Being female was the strongest predictor for their effectiveness. CONCLUSION A range of actions for depression, including medical and complementary interventions, were used and found to be helpful in a sample that had sought professional help for depression. Gender, age, depression and anxiety factors were all found to predict the use and perceived effectiveness of these strategies.

Abstract
PURPOSE To evaluate the results of balloon dacryocystoplasty in the treatment of complicated development of connatal obstructed nasolacrimal duct system. MATERIALS AND METHODS Dacryocystography under general anaesthesia was performed on 46 children with epiphora from birth and recurrent infection of the nasolacrimal duct system. 54 nasolacrimal ducts (8 children bilaterally) were treated with balloon catheter dilatation and antibiotic irrigation of the nasolacrimal sac. In all cases previous conservative treatment with eye drops and superficial massage of the lacrimal sac had failed. 11 children without clinical improvement were irrigated before catheter dilatation by an ophthalmologist. The ages ranged from 6 weeks to 7.5 years (mean 23.5 months). 39 dilatations were carried out as an out-patient procedure. The clinical results were confirmed by a questionnaire filled in by the parents. RESULTS 15 incomplete obstructions and 39 occlusions of the Hasner valve (n = 45) or of the nasolacrimal duct system (n = 9) were demonstrated with dacryocystography. Dilatation with a 2.5 mm ballon was successfully performed in all cases and the mean radiation time was 2.1 minutes. No relevant complications occurred. The mean follow up time was 18.4 months (3 - 41 months). 39 of 46 children showed no symptoms, 6 children seldomly experienced onset of epiphora. The symptoms did not improve in only one child. The cumulative clinical success rate is 98 %. CONCLUSION Following diagnostic dacryocystography, balloon catheter dilatation is a low risk and very successful treatment of complicated connatal obstructed nasolacrimal duct system.

Abstract
OBJECTIVE To better define treatment-resistant depression (TRD) so as to assist clinical management and refine treatment guidelines. METHOD In this study, we examine a broad range of clinical variables in depressed patients (n=196) referred to a tertiary referral Mood Disorders Unit (MDU). Information was collected from patients, referrers and assessors over a period of 32 months and included evaluations of treatments, treatment resistance and related variables. Data were analysed across trichotomized 'high', 'low' and 'no' treatment resistance groupings of patients. RESULTS A significantly greater proportion of patients with melancholia were amongst the high TRD group, and this was consistent across different strategies for evaluating melancholia. CONCLUSION Melancholia perhaps provides a prototypic TRD subset that perhaps reflects some innate aspects of melancholic depression or factors such as the impact of ageing. Research into TRD is needed to both replicate this finding and perhaps explicate it further.

Abstract
OBJECTIVE To determine the efficacy of balloon catheter dacryocystoplasty in treating stenoses of the common canaliculus. MATERIALS AND METHODS Between 1997 and 2004, elective balloon catheter dilatation was performed under local anesthesia in 36 patients with epiphora and dacryocystography (DCG)-proven high-grade stenosis of the common canaliculus. Eight of the 36 patients had additional stenosis of the nasolacrimal duct. A 2.5-mm diameter balloon was used for common canaliculus obstructions, a 3-mm balloon for nasolacrimal duct obstructions. RESULTS Dilatation was technically successful in 34/36 patients. In 2/36 patients the guide wire could not be advanced beyond the obstruction. There were no complications. During a mean follow-up of 9 months restenosis occurred in 4/36 patients, in one of whom it led to occlusion of the common canaliculus; a chronic dacryocystitis had already resulted in occlusion of the common canaliculus in this patient's other eye. Two of four restenoses were successfully dilated in a second procedure. In one patient, a bilateral presaccal occlusion was suspected clinically. DCG revealed a high-grade common canaliculus stenosis in both eyes. After balloon catheter dilatation the patient was complaint free in one eye, and in the other eye symptoms improved. CONCLUSIONS The therapy of choice for common canaliculus stenoses in addition to canaliculodacryocystorhinostomy is silicone tube implantation. The results of both procedures, however, are often disappointing. Balloon catheter dilatation is a minimally invasive technique carried out under local anesthesia which represents an alternative therapy option for the treatment of stenoses of the common canaliculus.

Abstract
The authors report a 54-year-old woman with papillary thyroid carcinoma (Lindsay type, pT2 N0 M1) with pulmonary metastases. After a total thyroidectomy, a series of 3 radioiodine therapies were performed with a cumulative dose of 700 mCi I-131. After termination of the therapy, the patient was initially without complaints, but approximately 6 months later, epiphora was noted, first only of the right eye and eventually of both eyes. A whole-body I-131 scan performed 1 year after final radioiodine therapy showed atypical tracer accumulation in both medial orbital regions. This finding was new compared with the scan that was done 1 year before. Dacryocystography revealed bilateral occlusion of the lacrimal drainage system. A review of the literature shows that epiphora and lacrimal duct alterations are rarely investigated and potentially underestimated side effects after high-dose radioiodine therapy.

Abstract
PURPOSE To examine the clinical outcome of the ballon dilatation in stenosis and obstruction of the nasolacrimal duct. MATERIAL AND METHODS 63 patients (69 nasolacrimal duct systems) with epiphora and proven obstruction of the nasolacrimal duct were treated with ballon dilatation, respectively Stentimplantation. In 55 cases there was a pre- or postsaccal stenosis, in 14 cases an occlusion of the nasolacrimal duct system. The diagnosis was established by dacryocystography. RESULTS Technical success was obtained in 61 cases (n=50/55 stenosis; n=11/14 occlusions). Over a mean follow-up of 6 months patency of the nasolacrimal duct system was achieved in 83,6% (46/55) in stenosis. In occlusion the clinical outcome was 42,9% (6/14). CONCLUSION Balloon dacryocystoplasty and Stentimplantation are minimal-invasive alternatives, performed in local anesthesia that recover the normal anatomy of the nasolacrimal duct system. They are a good alternative in the treatment of epiphora caused by nasolacrimal duct obstructions.

Abstract
Mutations in the fukutin-related protein (FKRP) have recently been demonstrated to cause limb girdle muscular dystrophy type 2I (LGMD2I), one of the most common forms of the autosomal recessive LGMDs in Europe. We performed a systematic clinical and muscle MRI assessment in 6 LGMD2I patients and compared these findings with those of 14 patients with genetically confirmed diagnosis of other forms of autosomal recessive LGMDs or dystrophinopathies. All LGMD2I patients had a characteristic clinical phenotype with predominant weakness of hip flexion and adduction, knee flexion and ankle dorsiflexion. These findings were also mirrored on MRI of the lower extremities which demonstrated marked signal changes in the adductor muscles, the posterior thigh and posterior calf muscles. This characteristic clinical and MRI phenotype was also seen in LGMD2A. However, in LGMD2A there was a selective involvement of the medial gastrocnemius and soleus muscle in the lower legs which was not seen in LGMD2I. The pattern in LGMD2A and LGMD2I were clearly different from the one seen in alpha-sarcoglycanopathy and dystrophinopathy type Becker which showed marked signal abnormalities in the anterior thigh muscles. Our results indicate that muscular MRI is a powerful tool for differentiating LGMD2I from other forms of autosomal recessive LGMDs and dystrophinopathies.

Abstract
OBJECTIVE To further develop a 'spectrum model' for non-melancholic disorders that encompasses underlying personality styles and clinical patterning. METHOD In a sample of patients with non-melancholic depression, we studied four personality constructs influencing risk to depression, assessing associational strength and specificity between personality scores and symptom and coping response patterns. RESULTS Analyses refined four personality dimensions (anxious worrying, irritability, social inhibition, and self-centredness) for testing the model. For all dimensions, personality style was specifically linked with a mirroring 'coping' response. Quantification of specific links allowed development of a spectrum model for the non-melancholic depressive disorders in which underpinning personality style showed some specific links with the clinical 'pattern' of symptoms and coping repertoires. CONCLUSION The model has the capacity to assist clinical assessment, identify aetiological personality influences and allow specific treatment effects for the heterogeneous non-melancholic depressive disorders to be determined.

Abstract
PURPOSE To examine the clinical outcome of the balloon dilatation in stenosis of the canaliculus communis. METHOD 18 nasolacrimal ducts with epiphora and proven obstruction of the canaliculus communis by dacryocystography (DCG) were treated with balloon dilatation in local anaesthesia. All patients were treated electively. RESULTS In 16/18 cases the balloon dilatation was technically successful, in 2 patients the guide wire failed to pass the obstruction and the wire could not be placed in the nasal cavity. There were no complications. Over a mean follow-up of 6 months there were 2 reobstructions, one of these led to an occlusion of the canaliculus communis. 14/18 (77,8%) cases after DCP were treated successful, 11/18 cases were free of symptoms after DCP, in 4/18 cases the epiphora improved. CONCLUSIONS Until recently in stenosis of the canaliculus communis the only therapeutic option was surgical procedure followed by silicone tube intubation. The results were often disappointing. In contrast to this balloon dacryocystoplasty is a minimally-invasive alternative in the therapy of stenosis of the canaliculus communis resulting in good clinical outcome during follow up.
