Abstract
BACKGROUND Medication nonadherence is a common problem in renal transplant recipients (RTRs). Mobile health approaches to improve medication adherence are a current trend, and several medication adherence apps are available. However, it is unknown whether RTRs use these technologies and to what extent. In the present study, the mobile technology affinity of RTRs was analyzed. We hypothesized significant age differences in mobile technology affinity and that mobile technology affinity is associated with better cognitive functioning as well as higher educational level. METHODS A total of 109 RTRs (63% male) participated in the cross-sectional study, with an overall mean age of 51.8 ± 14.2 years. The study included the Technology Experience Questionnaire (TEQ) for the assessment of mobile technology affinity, a cognitive test battery, and sociodemographic data. RESULTS Overall, 57.4% of the patients used a smartphone or tablet and almost 45% used apps. The TEQ sum score was 20.9 in a possible range from 6 (no affinity to technology) to 30 (very high affinity). Younger patients had significantly higher scores in mobile technology affinity. The only significant gender difference was found in having fun with using electronic devices: Men enjoyed technology more than women did. Mobile technology affinity was positively associated with cognitive functioning and educational level. CONCLUSIONS Young adult patients might profit most from mobile health approaches. Furthermore, high educational level and normal cognitive functioning promote mobile technology affinity. This should be kept in mind when designing mobile technology health (mHealth) interventions for RTRs. For beneficial mHealth interventions, further research on potential barriers and desired technologic features is necessary to adapt apps to patients' needs.

Abstract
BACKGROUND AND OBJECTIVE Changes between health care sectors represent a critical phase in long-term pharmacotherapy. The aim of the Hei CARE(®) project was to close the communication gap at the interface between primary care physicians (PCP), hospital physicians and patients, and to improve quality and safety of pharmacotherapy. METHODS Physicians who enrolled patients with long-term pharmacotherapy were able to participate in the Hei CARE(®) project. After enrolment the patient's medication was entered in the internet-based medication knowledge data base AiD PRAXIS and checked for medication interactions and optimized if necessary. At hospitalisation medication was transferred electronically to the hospital (AiD KLINIK(®)) and on discharge integrated in the discharge letter and faxed to the primary care physician (PCP). The project was evaluated using quantitative and qualitative methods. Hei CARE(®) -cases, in which medication was transferred electronically as planned, were compared with the other cases. PCPs' experiences were collected in focus groups. RESULTS One thousand and three chronically ill patients of 56 primary care practices participated. 259 patients were hospitalized between October 2005 and March 2009 of which entrance and discharge medication were transferred both ways via the electronic prescribing platform in 67 cases. The number of changes in medication was reduced in comparison to the other cases. Participating PCPs reported positive changes through Hei CARE(®) as well as further potential for optimizing communication across health care sectors. CONCLUSION Use of a common internet-based medication knowledge data base (Hei CARE(®) ) in both health care sectors reduced the number of changes in pharmacotherapy. Seamless care in chronically ill patients was thereby improved. The project also demonstrated that improving communication across health care sectors is a slow process.

Abstract
BACKGROUND AND OBJECTIVE Patients with chronic disease have to rely on safe and efficacious drug treatment. They therefore need individual information on their medicaton, in which counselling within the setting of general practice plays a pivotal role. However, information that seems to be relevant from the doctor's point of view is not necessarily consistent with the information patients consider to be necessary. The question was addressed in this study on to what extent patients are satisfied with the information they have received on their medication in general practice? METHODS A standardized questionnaire consisting of the SIMS-D (German version of the Satisfaction with Information about Medicines Scale) and MARS-D (German version of the Medication Adherence Report Scale) was sent to 834 chronically ill patients between March 2007 and April 2008. RESULTS Patients felt quite satisfied with the information they received on "action and usage" of medication (mean 6.95; range 0 - 9). They were not quite so satisfied with the information they received on "potential problems of medication". Self-reported adherence showed a high mean of 23.6 (range 5 - 25). Less than half of the doctors (43.6 %) inquired "always" or "often" whether patients were taking any other drugs than those prescribed. CONCLUSION Patients wish to have more information on potential drug-related problems. More attention needs to be given to a structured review of drugs prescribed in general practice.

Abstract
A 52-year-old patient presented with an orbital swelling and exophthalmos that enlarged over a period of about 40 years. The clinical examination showed massive exophthalmos and ptosis of the right eye without diplopia. The radiological investigation (MRI, CT and ultrasound) showed an unclear intraorbital mass with erosion of the orbital floor, infraorbital rim and orbital roof. The lesion was diagnosed histologically as a plexiform neurofibroma. The patient did not present any features of neurofibromatosis type 1 (NF-1) and molecular genetic analysis was unable to uncover a pathogenic sequence alteration in the NF-1 gene. Owing to the absence of clinical and ophthalmologic symptoms and the improbability of complete removal, the patient refused surgical intervention.

Abstract
The aim of this study was to compare sensitivity, specificity, accuracy and positive and negative predictive value for high-resolution ultrasonography (HR-US) in diagnosing degenerative changes, effusion and disk displacement using magnetic resonance imaging (MRI) as a reference. Over a period of 6 months, 100 patients with TMJ disorders (200 TMJs) were investigated by an experienced radiologist with HR-US and magnetic resonance imaging (MRI). The MRI investigation showed degenerative changes in 190 joints (95%), while an effusion was found in 59 (29.5%) joints. At closed-mouth position a disc dislocation was found in 138 joints (69%) and in maximum-mouth-opening position disc dislocation was diagnosed in 76 joints (38%). In the determination of degenerative changes HR-US showed a sensitivity of 94%, a specificity of 100% and an accuracy of 94%. In the detection of effusion HR-US yielded a sensitivity of 81%, a specificity of 100% and an accuracy of 95%. In the determination of disk displacement at closed-mouth position HR-US showed a sensitivity, specificity and an accuracy of 92% each. At maximum-mouth-opening position HR-US reached a sensitivity of 86%, a specificity of 91% and an accuracy of 90%. The results of the current study imply that HR-US is a valuable diagnostic imaging method of the TMJ which can be used as an alternative method to a MRI-investigation, but is yet not able to replace it. Further studies have to be done to reduce false-negative results.

Abstract
PURPOSE The aim of the study was to evaluate the interobserver variation of the ultrasound diagnosis of orbital floor fractures and fractures of the infraorbital rim. MATERIAL AND METHODS A total of 25 patients with a clinical diagnosis of an orbital trauma were investigated prospectively by computed tomography (CT) and ultrasonography (US). Inter-observer variation was calculated using the lambda coefficient (lambda). The US images were reassessed by two inexperienced investigators. RESULTS The lambda value for the US investigation of the orbital floor showed poor reliability comparing the US findings with the results of the re-investigators. The comparison between the two re-investigators showed a good reliability for the US evaluation of the orbital floor. The lambda for the US investigation of the infraorbital margin showed a good reliability comparing the US findings with the results of the both re-investigators. The comparison of the two re-investigators showed a good reliability as well. CONCLUSION Ultrasound is not yet an alternative method for the evaluation of orbital floor fractures and fractures of the infraorbital margin. To replace CT which is accepted as the current gold standard, further studies have to be done to reach a better diagnostic quality of the method and to achieve a better calibration of the investigations.

Abstract
The aim of the study was to investigate the diagnostic value of ultrasonography (US) in orbital floor fractures and orbital rim fractures with a curved array scanner. Over a period of 10 months, 60 patients with an orbital trauma have been investigated. Orbital trauma was defined by clinical and ophthalmologic investigation. Computed tomography (CT) was used as the reference method to evaluate the diagnostic value of US in the determination of an orbital floor fracture and was performed by a well-experienced radiologist. Coronal and sagittal images were made. The US investigation was performed with a 7.5 MHz curved array transducer.The US investigation of the infraorbital rim showed a sensitivity of 94% and a specificity of 92% with a diagnostic accuracy of 92%. The positive predictive value (PPV) reached 91% and the negative predictive value (NPV) reached 92%, while the US investigation of the orbital floor showed a sensitivity of 95% and a specificity of 100% with a diagnostic accuracy of 98%. PPV reached 100% and NPV reached 77%. Ultrasonography is a cost-effective and widely available method without disadvantages such as radiation exposure. The results in the current study imply that ultrasonography can be used as an alternative method in the investigation of orbital floor fractures.

Abstract
PURPOSE The aim of the study was to investigate the incidence of temporomandibular disorders (TMD) in juvenile patients with rheumatic diseases. Furthermore, correlations between the degree of the rheumatic disease and the clinical symptoms were evaluated. MATERIAL AND METHODS In a prospective investigation the temporomandibular joints of 48 children with rheumatic diseases were evaluated clinically regarding clicking, crepitation, pain, duration of the rheumatic disease, and the number of affected peripheral joints. The degree of rheumatic disease was assessed with Steinbrocker's classification. RESULTS 26 patients (54.17%) showed clinical symptoms of TMD. No significant correlation was found between the degree of the rheumatic disease and the awareness of TMD. A high number of affected peripheral joints does not lead to a significant increase of TMD. A significant correlation between the duration of the rheumatic disease and TMD could be detected. A significant correlation between the duration of the rheumatic disease and clicking or crepitation was found ( p=0.011). CONCLUSION Rheumatic diseases lead to a higher incidence of TMD in juvenile patients. A longer duration of rheumatic diseases leads to a higher incidence of TMD.

Abstract
PURPOSE The purpose of the study was to evaluate the diagnostic value of a curved array scanner in the diagnosis of medial and lateral orbital wall fractures. MATERIAL AND METHODS Fifty-three patients with the clinical diagnosis of an orbital trauma were investigated prospectively within a period of 16 months by CT and ultrasonography. The intraoperative findings were used as a reference. RESULTS CT reached a sensitivity of 100% and a specificity of 96% in the diagnosis of medial orbital wall fractures, while ultrasound yielded a sensitivity of 80% and a specificity of 96%. There was no significant difference found between CT and ultrasonography ( p=0.402). In the investigation of lateral orbital wall fractures, CT reached a sensitivity of 88% and a specificity of 87%, while ultrasonography yielded a sensitivity of 97% and a specificity of 95%. Ultrasonography achieved significantly better results than CT ( p=0.008). CONCLUSION The ultrasound investigation with a curved array scanner could be used as an additional method in the diagnosis of medial and lateral orbital wall fractures. Further technical improvements of the transducers need to be developed to increase the sensitivity of ultrasound in the diagnosis of medial orbital wall fractures.

Abstract
The purpose of this study was to evaluate ultrasonography (US) and computed tomography (CT) in detecting lymphnodes of the neck affected with squamous cell carcinoma. From 1987 to 1999 the data from 203 untreated patients with a diagnosis of cancer in the maxillofacial have been investigated. Of these, 115 had a primary squamous-cell carcinoma. US diagnosis was made by an oral- and maxillofacial surgeon experienced in US of the head and neck. CT diagnosis was made by a well-experienced radiologist. The following lymph node levels were assesed: level I (submental and submandibular lymphnodes), level II (lymphnodes distal to level I and confined to the region above the skin crease at or just below the level of the thyroid notch), level III (lymphnodes distal to level II and confined to the anterior cervical triangle including those deep to the sternocleidomastoid muscle), and level IV (lymphnodes distal to level III and confined to the posterior cervical triangle). For all levels US yielded a sensitivity of 71%, and a specificity of 87%, while CT showed a sensitivity of 32% and a specificity of 96%. The sensitivity of US decreased from level I to level IV, whereas the specificity increased from level I to level IV. For lymphnode levels I and II US may be useful for the detection of local metastases while for the other levels the application of advanced techniques of US may have to be investigated.

Abstract
PURPOSE The aim of this study was to evaluate post-traumatic ocular motility in orbital floor fractures in relation to the severity of the fracture and concomitant injuries. MATERIAL AND METHODS Over a period of 6 years, data from 435 patients with orbital floor fractures were re-evaluated. Ocular motility was divided into abduction, adduction, upgaze and downgaze movements. RESULTS In 54.3% of the cases, there was a reduction in ocular motility. A reduced motility with a movement >20 degrees was found in most of the cases. Concomitant injuries to the eye resulted in a significant increase in the reduction of motility. This reduction depended on the severity of the orbital floor fracture. A reduced upgaze movement was the most common complication in all types of fractures. CONCLUSION Ocular motility can act as an indication of the severity of the orbital fracture. Concomitant injuries to the eye resulted in a higher incidence of reduced ocular motility.

Abstract
PURPOSE The purpose of this study was to investigate patients with a clinical diagnosis of internal derangement to determine the diagnostic value of static high resolution ultrasonography (HR-US) when compared with magnetic resonance imaging (MRI). PATIENTS Sixty-six patients (132 temporomandibular joints [TMJs]) with a clinical diagnosis of internal derangement were investigated by HR-US and MRI. METHODS MRI and HR-US investigations were performed by experienced radiologists. The sonograms were done with a real-time 12-Mhz linear-array scanner. The HR-US interpretation errors were re-evaluated retrospectively by the same radiologist knowing the MRI results by comparing these with the 'prospective' and 'retrospective' diagnoses. The prospective and retrospective diagnoses were also compared with each other. RESULTS Eighty-seven of the 132 TMJs had a disc displacement proved by MRI in the closed-mouth position. At maximum mouth opening, 54 TMJs had a disc displacement. The prospective interpretations showed a sensitivity and specificity of 78% each, accounting for an accuracy of 78%. At maximum mouth opening, HR-US resulted in a sensitivity of 61%, a specificity of 88% and an accuracy of 77%. The retrospective interpretations yielded a sensitivity of 90%, a specificity of 84% and an accuracy of 88% in the closed-mouth position. At maximum mouth opening, HR-US showed a sensitivity of 73%, a specificity of 95% and an accuracy of 86%. CONCLUSION HR-US is suitable for the detection of disc displacements in the TMJ. However, further studies may be warranted to reduce the proportion of false-positive interpretations, thereby avoiding the application of unnecessary treatment.

Abstract
PURPOSE The aim of this retrospective study was to investigate the long-term outcomes of dental injuries. Subluxated and laterally luxated teeth were evaluated according to the findings of CO2 sensitivity, obliteration, pulpal sclerosis, and the duration of post-traumatic fixation of the injured teeth. MATERIAL AND METHODS The data of 725 patients were analyzed retrospectively over a period of 14 years. Of these, 108 patients could be investigated for a long-term follow-up. Dental trauma was classified according to the degree of luxation (I-III). RESULTS There was a significant correlation between the degree of luxation and the post-traumatic findings of CO2 sensitivity. There was no significant correlation between the degree of luxation and the post-traumatic findings of apical inflammation, pulpal sclerosis, and/or obliteration. Long-term fixation of injured teeth had no effect on the short- and long-term occurrence of pathologic processes at the root such as root resorption. CONCLUSION The post-traumatic finding of CO2 sensitivity was related to the degree of luxation of the injured teeth. Apical inflammation, pulpal sclerosis, and obliteration were not related to the degree of luxation. The results suggest that long-term fixation of injured teeth has no negative effects on the long-term outcomes of subluxated and laterally luxated teeth.
