RESUMEN
Distal radius fracture (DRF) is a common injury, affecting both function and activity performance. Postoperative rehabilitation is an essential part of the treatment of a surgically treated DRF. The study aims were to assess pain, hand function, activity performance and apprehensiveness and their association, during the first three months after a surgically treated DRF. Eighty-eight patients with a DRF were assessed for pain, hand function, activity performance and apprehensiveness three days and two, six and 12 weeks after surgery. The results indicated that pain, range of motion (ROM), grip strength, apprehensiveness, and activity performance (PRWE) improved significantly between follow-ups (p < .001-.01). Apprehensiveness correlated moderately with activity performance on all visits (0.40-0.47, p < .01), which implies a correlation between the variables, but the regression model showed that the differences in the PRWE at twelve weeks cannot be explained by the differences in apprehensiveness or range of motion at cast removal. At 12 weeks, the study participants had regained almost 70% of their grip strength and 74-96% of the ROM of the uninjured hand.The study shows that, during the study period, the participants improved in both pain, hand function and activity performance, and indicates that a simple question on apprehensiveness in terms of using the injured hand in daily life could be an important factor in distal radius fracture rehabilitation.

OBJECTIVE: This study is perhaps the first to evaluate the influence of depression on the relationship between climacteric symptoms and food and nutritional insecurity (FNI). METHODS: In this cross-sectional study with a relatively large sample of climacteric women (N = 400), sociodemographic and clinical variables were investigated. We measured FNI, depression and climacteric symptoms with psychometrically sound instruments, namely the Brazilian Food Security Scale, the Center for Epidemiologic Studies Depression Scale and the Kupperman Index, respectively. RESULTS: Statistically significant differences were observed in the means of FNI according to education, income, marital status, history of depression, use of antidepressants and current depression. Furthermore, depression had strong indirect effects on the relationship between climacteric symptoms and FNI. CONCLUSION: Our study suggests that targeting depression could benefit climacteric women, especially those with severe symptoms and in FNI.

BACKGROUND: The Michigan Hand Outcomes Questionnaire-MHQ-is a well-known self-assessment questionnaire, where patients' own perception in terms of recovery, pain and the ability to return to activities of daily living is assessed. The purpose of the study was to translate and culturally adapt the Michigan Hand Outcomes Questionnaire to Swedish and to test the validity and reliability in patients with surgically treated distal radius fractures. METHODS: The cross-cultural adaptation and the translation process were conducted according to predefined guidelines. Seventy-eight patients with surgically treated distal radius fractures completed the translated version of the questionnaire on their six-week follow-up visit. RESULTS: The translation and cross-cultural adaptation process revealed no major linguistic or cultural issues. The internal consistency of the MHQ-Swe ranged from 0.77 to 0.94 at test 1 and from 0.81 to 0.96 at test 2 for all subscales, which indicates good internal consistency in the subscales. The hand function subscale revealed the lowest results and work performance the highest. The ICCs showed excellent test-retest reliability, ranging from 0.77 to 0.90 on all MHQ subscales and 0.92 on total score. The highest results for the ICC were seen in the satisfaction subscale (ICC = 0.90), while the lowest were seen in the aesthetic subscale (ICC = 0.77). The correlation analysis between the MHQ-Swe, PRWE and VAS showed a generally moderate to high correlation for all the subscales. CONCLUSIONS: The Swedish version of the MHQ, the MHQ-Swe, showed good validity and reliability and it is therefore an appropriate and relevant questionnaire for use in patients with surgically treated distal radius fractures.

Objective: This study evaluated the associations between food intake - especially omega-3 (n-3) - and depressive symptoms in climacteric women.Methods: Four hundred climacteric women were included in this research. The Kupperman Index, the Center for Epidemiologic Studies Depression Scale, and a 3-day food diary were used to investigate climacteric symptoms, depressive symptoms, and food intake, respectively. Sociodemographic, clinical, and anthropometric variables were also explored.Results: Statistically significant associations were observed between depression and climacteric symptoms, climacteric phase, previous history of depression, antidepressant drug use, family income, sleep pattern, and consumption of carbohydrates, fiber, polyunsaturated fatty acids, magnesium, zinc, and vitamins C, D, and B12. No association was observed between n-3 consumption and depression.Conclusion: Climacteric symptoms and food intake are important factors linked to depression during the climacteric period. Further studies are needed to clarify the changes in this phase of women's lives, as well as to investigate the role of the diet in the depression treatment or prevention.

BACKGROUND AND AIMS: There is a risk of decreased physical function, quality of life and persistent pain after open surgery for esophageal cancer. There are currently no studies that evaluate the effect of any postoperative intervention, including physical exercises, after this type of surgery. The aim of the study was therefore to evaluate the effect of a training intervention after Ivor-Lewis resection of the esophagus. MATERIAL AND METHODS: Patients scheduled for esophagus resection according to Ivor-Lewis were randomized to an intervention group or a control group. The training intervention started at discharge and lasted three months. Before discharge, patients were given three leaflets with exercises to increase range of motion in the affected area and exercises aiming to restore lung function and physical function. All exercises were described in detail and the patients carried out the ones in the first program under supervision. Before surgery and three months after discharge, the patients estimated their level of physical function, level of physical activity, and quality of life. They also underwent spirometry, measurements of range of motion in the rib cage, spine, and shoulders, and three functional tests. Comparisons of differences within and between the groups were made. RESULTS: A total of 43 of 64 randomized patients participated in the follow-up. Postoperatively, the patients in the intervention group had a significantly higher degree of physical function and less deteriorated range of motion in right shoulder flexion and thoracic left lateral flexion. There were no significant differences between the groups in lung function, pain, or quality of life. CONCLUSION: The results of the three-month intervention indicate that specific training can positively affect physical function and range of motion to preoperative values. The intervention was well tolerated, and no side effects were registered.

Clinical observations suggested that gamma-hydroxybutyrate (GHB) protects nerve cells against death but the direct proofs are missing. Here, we combined several approaches to investigate GHB capacity to protect human neuroblastoma SH-SY5Y cells against hydrogen peroxide (H2O2)-induced death. To increase the patho-physiological relevancy of our study, we used native SH-SY5Y cells and SH-SY5Y cells stably transfected with the wild-type amyloid-precursor-protein (APPwt) or control-vector-pCEP4. Trypan Blue exclusion and MTT (3-[4,5-dimethylthiazol-2-yl]-2,5-diphenyl-tetrazolium-bromide) assays combined with pharmacological analyses showed that H2O2 reduced native and genetically modified cell viability and APPwt-transfected cells were the most vulnerable. Terminal deoxynucleotidyl transferase-mediated dUTP nick end labeling (TUNEL) and activated caspase-3 staining assessed by flow cytometry revealed a basally elevated apoptotic signal in APPwt-transfected cells. Reverse-transcription, real-time quantitative polymerase chain reaction (qPCR) and Western blotting showed that mRNA and protein basal ratios of apoptotic modulators Bax/Bcl-2 were also high in APPwt-transfected cells. GHB efficiently and dose-dependently rescued native and genetically modified cells from H2O2-induced death. Interestingly, GHB, which strongly decreased elevated basal levels of TUNEL-staining, activated caspase 3-labeling and Bax/Bcl-2 in APPwt-transfected cells, also counteracted H2O2-evoked increased apoptotic markers in native and genetically modified SH-SY5Y cells. Since GHB did not promote cell proliferation, anti-apoptotic action through the down-regulation of Bax/Bcl-2 ratios and/or caspase 3 activity appears as a critical mechanism involved in GHB-induced protection of SH-SY5Y cells against APPwt-overexpression- or H2O2-evoked death. Altogether, these results, providing multi-parametric evidence for the existence of neuroprotective action of GHB, also open interesting perspectives for the development of GHB analog-based strategies against neurodegeneration or nerve cell death.

BACKGROUND: Posterior reversible encephalopathy syndrome (PRES) affects predominantly the parietal and occipital lobes. Frequent clinical features are epileptic seizure, altered mental status and visual disturbances. CLINICAL PRESENTATION: We present the first case of a patient with pericarditis and mitral valve insufficiency, who developed PRES after application of a glycerolnitrate patch day three post-operatively and whose neurological deficits improved within 2 days after withdrawal of patch therapy. CONCLUSION: The precise pathomechanism of PRES is unknown. The lower sympathetic innervation of the posterior circulation may be one explanation for its particular vulnerability to vasodilatation caused by glycerolnitrate.

AIM: To evaluate central retinal thickness and foveal function using optical coherence tomography (OCT) and the Rarebit Fovea Test (RFT) in patients with diabetes without previously known retinopathy or maculopathy. METHOD: Forty-two patients with diabetes mellitus (DM) were selected from the screening records at St Erik Eye Hospital. Inclusion criteria were absence of macular or other retinal changes at previous screening examination and best corrected visual acuity >/=1.0. These patients and 42 healthy controls were examined with the recently developed RFT, and retinal thickness was measured using OCT. Lens thickness and light scatter were evaluated by Scheimpflug photography. RESULTS: Significantly more DM subjects (12/42) had a subnormal RFT result compared with the controls (2/42) (p = 0.007). None of the 12 DM subjects had maculopathy, one had mild non proliferative diabetic retinopathy, and five had minimal non-proliferative diabetic retinopathy. The retinal thickness in the pericentral zone was significantly (p<0.05) thinner in DM patients with subnormal RFT compared with the controls. CONCLUSION: Decreased RT and subnormal RFT results were found in a subgroup of diabetes patients, despite normal screening results. Prospective studies are under way to evaluate the prognostic implications.

UNLABELLED: Revision of an acetabular component in a patient who has severe periacetabular bone loss is a complex problem, particularly when there is not enough bone stock to allow placement of an acetabular component near the normal anatomical hip center. To fill the defect, a valuable option for revision arthroplasty is the cementless oblong revision cup (LOR). METHODS: 50 consecutive revisions of the acetabular component were performed in 48 patients. The mean age at the time of revision was sixty-one years (range, thirty-three to seventy-eight years). Forty-eight hips were available for follow-up, at a mean of thirty-two months (range, eighteen to sixty-one months). The acetabular defect classified according to Paprosky, the migration and the radiolucencies were followed radiologically. RESULTS: 8 hips (16 %) were revised again: two because of infection (4 %) and six because of instability (12 %). The revised hips are not associated to the preoperative degree of acetabular defect (34 % defect type III) (P > 0.05). The mean Harris Hip score was corrected from 36.5 (range, 7.5 to 92.5) to 78.2 points (range, 47.6 to 97.6) (P < 0.01). The mean d'Aubigné Score was corrected from 8.3 (range, 4 to 6) to 15 points (range, 10 to 18) (P < 0.01). Neither pre- nor postoperative results were associated to the degree of acetabular defect (P > 0.05). However, patients with multiple revisions had a significantly reduced clinical outcome than patients with the first revision (P < 0.05). The hip center of rotation, cranially placed to the contralateral side (0.92 cm) was corrected by the revision to a more normal anatomic rotation center (0.27 cm). Partial zonal radiolucencies, always smaller than 1.5 mm were seen in 30 % of the patients. The mean migration of the acetabular component was not significant (P > 0.05). CONCLUSION: The authors support the use of the cementless oblong revision cup if contact can be made with host bone to more than 50 %. If this is not possible, acetabular bone reconstruction combined with a roof ring and a cemented cup is the component of choice.

In a randomized study, using psychometric assessment, we evaluated two training programs before and after surgical treatment of lumbar disc herniation. 26 patients were treated according to an early active training program (treatment group). 24 patients followed a traditional less active training program (control group). Before surgery, the patients filled in the following questionnaires 3 and 12 months after surgery: Multidimensional Pain Inventory (MPI), State and Trait Anxiety Inventory, and Beck Depression Inventory. Pain was assessed by the patient's pain drawing and a visual analog scale. Both groups improved as regards pain severity and state of anxiety. The MPI parameter, pain interference, improved more in the early active treatment group than in the control group. This suggests that the early active training program has a positive effect on the way patients cope with pain in their daily lives.

BACKGROUND AND PURPOSE: Functional connectivity MR (fcMR) imaging is used to map regions of brain with synchronous, regional, slow fluctuations in cerebral blood flow. We tested the hypothesis that focal cerebral lesions do not eradicate expected functional connectivity. METHODS: Functional MR (fMR) and fcMR maps were acquired for 12 patients with focal cerebral tumors, cysts, arteriovenous malformations, or in one case, agenesis of the corpus callosum. Task activation secondary to text listening, finger tapping, and word generation was mapped by use of fMR imaging. Functional connectivity was measured by selecting "seed" voxels in brain regions showing activation (based on the fMR data) and cross correlating with every other voxel (based on data acquired while the subject performed no task). Concurrence of the fMR and fcMR maps was measured by comparing the location and number of voxels selected by both methods. RESULTS: Technically adequate fMR and fcMR maps were obtained for all patients. In patients with focal lesions, the fMR and fcMR maps correlated closely. The fcMR map generated for the patient with agenesis of the corpus callosum failed to reveal functional connectivity between blood flow in the left and right sensorimotor cortices and in the frontal lobe language regions. Nonetheless, synchrony between blood flow in the auditory cortices was preserved. On average, there was 40% concurrence between all fMR and fcMR maps. CONCLUSION: Patterns of functional connectivity remain intact in patients with focal cerebral lesions. Disruption of major neuronal networks, such as agenesis of the corpus callosum, may diminish the normal functional connectivity patterns. Therefore, functional connectivity in such patients cannot be fully demonstrated with fcMR imaging.

BACKGROUND: UVA-induced photooxidation is considered to play an essential role in the pathogenesis of polymorphous light eruption (PLE), and topical pretreatment of skin with alpha-glucosylrutin (AGR), a potent plant-derived antioxidant, has been shown to significantly suppress photoprovoked PLE eruption. AIM: In order to further elucidate the optimum pretreatment regimen and to investigate the efficacy and skin compatibility of topical preparations containing AGR under field conditions, two controlled clinical studies were conducted in PLE patients. METHODS: In the first study, photoprovocation of PLE was performed in 20 patients, using UVA irradiation (4 x 60-100 J/cm(2)), applied to four test sites at the individual areas of predilection. One site served as an untreated control. The remaining three sites received treatment with a SPF 15 sunscreen containing 0.25% AGR (Eucerin Gel Cream Phase 2) 30 minutes before irradiation. Two of these sites were additionally pretreated with the corresponding AGR-containing vehicle (Eucerin Gel Cream Phase 1) twice daily for 3 and 7 days, respectively. The second study was conducted as a controlled in-use-test in patients with PLE (n = 27) or acne aestivalis (n = 3), who had suffered from the disease during their last year's vacation. They were educated to apply the pre-sun preparation to the formerly affected skin areas twice daily for 1 week before their planned vacation and to use the SPF 15 sunscreen 30 minutes before each vacation sun exposure. Symptoms were recorded in patients' diaries throughout the vacation and documented by a physician after their return. RESULTS: In the first study, protection of skin with the SPF 15 sunscreen alone led to a significant prevention of PLE symptoms, especially itch, compared with the control area. Pretreatment further reduced the severity of PLE significantly and led to total prevention in 19 patients. In the second study, whereas 92.6% had reported severe and 7.4% mild PLE in the last year, there were currently only 7.4% severe cases, with 25.9% mild and 29.6% questionable cases; 37% had no symptoms at all. Also, two out of three acne aestivalis patients had diminished symptoms after treatment. CONCLUSION: The results confirm the prophylactic efficacy of the antioxidant AGR in PLE, applied as SPF 15 sunscreen alone or additionally to pretreatment with a corresponding pre-sun preparation, and also show an effect in acne aestivalis patients.

BACKGROUND AND PURPOSE: In subjects who are performing no prescribed cognitive task, functional connectivity mapped with MR imaging (fcMRI) shows regions with synchronous fluctuations of cerebral blood flow. When specific tasks are performed, functional MR imaging (fMRI) can map locations in which regional cerebral blood flow increases synchronously with the performance of the task. We tested the hypothesis that fcMRI maps, based on the synchrony of low-frequency blood flow fluctuations, identify brain regions that show activation on fMRI maps of sensorimotor, visual, language, and auditory tasks. METHODS: In four volunteers, task-activation fMRI and functional connectivity (resting-state) fcMRI data were acquired. A small region of interest (in an area that showed maximal task activation) was chosen, and the correlation coefficient of the corresponding resting-state signal with the signal of all other voxels in the resting data set was calculated. The correlation coefficient was decomposed into frequency components and its distribution determined for each fcMRI map. The fcMRI maps were compared with the fMRI maps. RESULTS: For each task, fcMRI maps based on one to four seed voxel(s) produced clusters of voxels in regions of eloquent cortex. For each fMRI map a closely corresponding fcMRI map was obtained. The frequencies that predominated in the cross-correlation coefficients for the functionally related regions were below 0.1 Hz. CONCLUSION: Functionally related brain regions can be identified by means of their synchronous slow fluctuations in signal intensity. Such blood flow synchrony can be detected in sensorimotor areas, expressive and receptive language regions, and the visual cortex by fcMRI. Regions identified by the slow synchronous fluctuations are similar to those activated by motor, language, or visual tasks.

The benefits and pitfalls of implementing a Java-based system to distribute results and images to referring physicians are addressed. The basic requirements for and barriers to implementing this system in a non-picture archiving and communication system (PACS) environment will also be discussed. The majority of radiology information systems (RIS) and hospital information systems (HIS) currently only distribute the text data for radiology examinations. This is generally adequate for low-acuity exams in a relatively healthy patient; however, many clinicians prefer to review images so they can correlate the reported findings with the image data, as well as review the exam themselves. A web-based solution eliminates the need for specialized review software and/or hardware at each review site. In addition, there is no need for support personnel to travel to each site to set up and upgrade software.

After the completion of skin development, angiogenesis, i.e., the growth of new capillaries from pre-existing blood vessels, is held to occur in the skin only under pathologic conditions. It has long been noted, however, that hair follicle cycling is associated with prominent changes in skin perfusion, that the epithelial hair bulbs of anagen follicles display angiogenic properties, and that the follicular dermal papilla can produce angiogenic factors. Despite these suggestive observations, no formal proof is as yet available for the concept that angiogenesis is a physiologic event that occurs all over the mature mammalian integument whenever hair follicles switch from resting (telogen) to active growth (anagen). This study uses quantitative histomorphometry and double-immunohistologic detection techniques for the demarcation of proliferating endothelial cells, to show that synchronized hair follicle cycling in adolescent C57BL/6 mice is associated with substantial angiogenesis, and that inhibiting angiogenesis in vivo by the intraperitoneal application of a fumagillin derivative retards experimentally induced anagen development in these mice. Thus, angiogenesis is a physiologic event in normal postnatal murine skin, apparently is dictated by the hair follicle, and appears to be required for normal anagen development. Anagen-associated angiogenesis offers an attractive model for identifying the physiologic controls of cutaneous angiogenesis, and an interesting system for screening the effects of potential antiangiogenic drugs in vivo.

PURPOSE: To compare the severity level of diabetic retinopathy obtained when assessed from two versus only one 60 degrees photographic field using colour transparencies and red-free, black-and-white photographs. To compare the areal coverage of these two photographic strategies to that of seven-field 30 degrees photography. METHODS: Two ophthalmologists graded photographs of 74 eyes of 74 type I and II diabetes patients. Inter-method agreement was expressed in percentages and using kappa statistics and scatter-diagrams. The comparison of the approximate photographic areal coverage was done from diagrams using planimetry. RESULTS: The severity level of retinopathy when judged from two photographic fields was more severe in 13.5% (Grader 1) and in 16.2% (Grader 2) from colour transparencies and in 13.5% (Grader 1) and in 14.9% (Grader 2) from red-free black-and-white prints, as compared to assessments from only one field. Kappa values (0.84-0.86) for inter-method agreement for five pooled retinopathy levels revealed good agreement. Neither grader missed retinopathy requiring clinical assessment or treatment (levels > or = 47) when minimal retinopathy (levels 14-20) was detected using only one 60 degrees colour slide or red-free photograph. A second optic disc-centred field provided valuable additional information when more severe retinopathy lesions (levels > or = 30) were detected in the macula-centred field. One macula-centred 60 degrees photograph covered 60% and two 60 degrees photographs 80% of the area covered by seven-field 30 degrees photography. Two-field 60 degrees photography covers areas left outside seven-field 30 degrees photography. CONCLUSION: We propose the use of one macula-centred 60 degrees photograph when screening for the first lesions of diabetic retinopathy. After they have been found two-field 60 degrees photography is recommended.

The authors studied the predictive value of a psychometric evaluation of 50 patients (14 women, 36 men) with a mean age of 40 years who were treated by extirpation of a lumbar disc herniation. Patient satisfaction was evaluated by an unbiased observer. The Beck Depression Inventory (BDI), the State-Trait Anxiety Inventory (STAI), and a Pain Visual Analogue Scale (PVAS) were used to assess pain and psychological distress before surgery and 3 and 12 months after surgery. Two years after surgery, 37 patients were contented with the surgical outcome and 10 patients were not. Three patients did not return the questionnaire. Before surgery, the patients who later became discontented were more depressed, more anxious, and experienced more pain. In a discriminant analysis, a combination of BDI, STAI, and PVAS scores correctly classified 78% of the discontented and 76% of the contented patients. The study shows psychometric analysis is a valuable tool for predicting the outcome of surgical treatment for lumbar disc herniation.

A 17-year-old boy and a 12-year-old girl with cystic fibrosis (forced expiratory volume in 1 sec, 36% and 14% of predicted values, respectively) developed severe right-sided lung infections with abscess formations and complete atelectases unresponsive to medical therapy. In both patients, unilateral emergency pneumonectomy resulted in rapid clinical improvement. Despite her severe underlying lung disease, the girl experienced a remarkable increase in quality of life; 2 years after surgery, she died from respiratory failure. The male patient has now survived for 4 years, and lung transplantation still remains a therapeutic option for him. We believe that pneumonectomy is a valuable rescue therapy for patients with cystic fibrosis and intractable unilateral lung infections who are at high risk of dying while waiting for lung transplantation.
