RESUMEN

Aims: To develop a structured goal-set for use in programs for the assessment and management of prolonged disorders of consciousness (PDOC).Methods: A retrospective analysis of goals from a consecutive cohort of patients (n = 162) admitted to a specialist in-patient PDOC program in the UK from 2007 to 2018. Overall goal attainment was examined with Goal Attainment Scaling (GAS) using the GAS-Light method. Rates of individual goal-setting and achievement were examined for both standardized objectives (n = 2959) and personalized goals (n = 661). Goal statements from the personalized goals were independently reviewed and mapped to the domains of the existing structured objective set to identify any missing goal areas.Results: Mean outcome GAS T-scores were 47.2 (95% CI: 46.7, 47.6) and 47.7 (95% CI: 46.7, 48.8), respectively, for the standardized and personally set goals. These were closely correlated (r = 0.482, p < .001) with no significant difference between them. Analysis of goal achievement within each domain identified goals that were/were not likely to be achieved. An initial structured set of 20 standardized objectives in 12 domains was expanded and re-organized to produce a final-structured goal-set of 36 objectives in 18 domains.Conclusions: Developed through real-life clinical practice, this first published structured goal-set for PDOC programs now requires testing in other services/settings.

RESUMEN

Active implantable hearing devices were primarily developed for sensorineural hearing loss. The vibrator coupling mechanisms were oriented towards normal middle ear anatomy and function. The aim of this project was to modify the only fully implantable hearing device with an implantable microphone for application in congenital auricular atresia, Carina™, and to introduce the modified device into the clinic. A special prosthesis was developed for the transducer and its individual coupling achieved by a special cramping system. The system was implanted in 5 patients with congenital auricular atresia. Audiological results were good; with patients' hearing gain exceeding 30 dB HL. Anatomic limits to the system's indications and technical drawbacks are also discussed.

RESUMEN

BACKGROUND: Patients with air-bone gaps or combined hearing loss that cannot be corrected by tympanoplasty can be treated with bone conduction hearing aids. The disadvantages of conventional and percutaneous systems are, on one hand, the obvious external fixation components and on the other hand, the biological and psychosocial problems of open implants. This project was therefore set up to develop a semi-implantable, magnetically anchored transcutaneous bone conduction device, introduce it into clinical application and follow-up the results. PATIENTS AND METHODS: The principle of this bone conduction device is the magnetic coupling of an external vibrator via implanted double magnets. After extensive laboratory tests, this method was introduced into the clinic in 2006. Following the initial pilot study, 184 implantations in 143 patients have been performed in Recklinghausen since 2008. Long-term evaluation of 20 congenital atresia patients treated with these devices was possible. RESULTS: Worldwide, more than 3000 of these devices have been implanted. The operative implantation technique is relatively simple. With the new "upside down technique", bone removal is no longer necessary. The 2.6-mm thin implants are hardly noticeable. The hearing improvement is similar to that of other bone conduction hearing aids. CONCLUSION: This semi-implantable transcutaneous bone conduction hearing device is another option for patients with air-bone gaps, combined hearing loss or single-sided deafness.

RESUMEN

Malformations of the head and neck show a huge variety of -clinical symptoms with functional and esthetic consequences. Often times its rehabilitation requires multi-staged and multi-disciplinary procedures and concepts. They must consider eating, speech, mimic expression, hearing and "esthetics" or at least "normality". A survey of the most common head and neck malformations and their treatment options are presented here.

RESUMEN

BACKGROUND: Initial results on the application of the water-jet in a parotidectomy setting in an animal study demonstrate that there are morphologic changes which do, and some which do not, affect the clinial function of the facial nerve due to the different jet sizes and operating pressures used. In a further study the histomorphometric data of the facial nerve dissected by the water-jet should be evaluated and correlated to the different sizes of jet and operating pressures. MATERIAL AND METHODS: In total, 102 nerves (in 14 beagles) which had been dissected by water-jets of different sizes and operating pressures were evaluated. After an observation period of 21 days, including documentation of the clinical function of the facial nerve, the nerves were dissected. The number of nerve fibers and the diameter of the different nerve fibers were then evaluated. RESULTS: All nerve fibers dissected with jet sizes of 120 and 150 µm showed an identical cumulative frequency of fiber diameters. All nerve fibers dissected with a water-jet of 200 µm showed morphologic and clinical abnormalities and--in terms of nerve fiber diameters--clear differences to the nerve fibers dissected with 120- or 150-µm jets. Altogether, there is a decrease in fiber diameter along the nerve course. CONCLUSION: Our data show a shift of larger diameters of the nerve trunk to smaller diameters in the terminal nerve fibers. This phenomenon has not been described in the literature to date and is probably not due to the water-jet. Additionally, our data show that 22% of the original nerve fiber damaged by the water-jet is sufficient to preserve the nerve's clinical function.

RESUMEN

BACKGROUND: The postoperative facial nerve palsy is a complication after parotidectomy which one is afraid of. The waterjet seems to be a surgical technic which allows separating different tissues without destroying important structures like vessels and nerves. MATERIAL AND METHODS: Totally, 106 nerve preparations, done by the waterjet of 14 beagles, were evaluated. According to a defined procedure during parotidectomy by waterjet different cones and pressure were used. After a period time of 21 days the trunk, the frontal branch and both oral branches of the facial nerve of both sides were dissected. The tissue preparation was done using the standard technic for EM-sections. RESULTS: There are mainly changes due to the preparation like the reduction of nerve fibers and fibrosis depending which cones and pressure has been used. CONCLUSION: Therefore neither the size of the jet (120 or 150 µm) nor the operating pressure of 40 to 60 or 80 bar plays an important role for the function of the facial nerve. Damage to the nerve is mainly due to the preparation technic and the application time. Using the 200 µm jet there is regularly facial nerve damage.

RESUMEN

We present a technique to quantify computer simulation in rhinoplasty and to make individual templates to be used intraoperatively. With these templates the exact position and shape of the nasal dorsum, tip, columella and anterioar nasal spine can be controlled and adjusted. Due to our experience this techniques contributes to precise surgical outcome and patient's satisfaction.

RESUMEN

INTRODUCTION: Patients with air-bone-gaps that cannot be corrected successfully by tympanoplasty or with mixed hearing loss may be treated with bone conducting hearing aids. Their disadvantages are the obvious external fixation components or the biological and psychosocial problems of open implants. PATIENTS AND METHODS: The principle of these new bone conducting hearing aids is the magnetic coupling between implanted and external magnets. Twin-magnets are implanted into shallow bone beds in a one step procedure. The skin above the magnets is thinned out to a thickness of 4-5 mm, which reduces the attenuation to less than 10 dB compared to direct bone stimulation. RESULTS AND DISCUSSION: The holding strength of the external components is equivalent to partially implantable hearing aids and Cochlea implants and the hearing improvement is similar to other bone conducting hearing aids. We have found the comfort and safety of this system is significantly improved compared to conventional or percutaneous bone conducting hearing aids.

RESUMEN

The current guideline discusses conservative and surgical therapy of obstructive sleep apnea (OSA) in adults from the perspective of the ear, nose and throat specialist. The revised guideline was commissioned by the German Society of Ear-Nose-Throat, Head-Neck Surgery (DG HNO KHC) and compiled by the DG HNO KHC's Working Group on Sleep Medicine. The guideline was based on a formal consensus procedure according to the guidelines set out by the German Association of Scientific Medical Societies (AWMF) in the form of a"S2e guideline". Research of the literature available on the subject up to and including December 2008 forms the basis for the recommendations. Evaluation of the publications found was made according to the recommendations of the Oxford Centre for Evidence-Based Medicine (OCEBM). This yielded a recommendation grade, whereby grade A represents highly evidence-based studies and grade D those with a low evidence base.

RESUMEN

RATIONALE: The gut-brain axis includes bidirectional communication between intestinal microbiota and the central nervous system. Bifidobacterium and Lactobacillus spp. have been implicated in psychological health, such as depression, through various pathways (e.g. inflammation). Research needs a better understanding of direct and indirect effects through examination of psychological factors that make people susceptible to, or offer protection against, depression. OBJECTIVE: This study investigated the relationships between gut microbiota, inflammation and psychological risk and resilience factors for depression. METHODS: Forty participants (13 m/27 f) recruited from the general population completed self-report questionnaires for depression, self-judgement, over-identification and affective and cognitive empathy. Faecal and blood samples were taken to assay microbiota (Bifidobacterium; Lactobacillus spp.) and pro-inflammatory molecules (C-reactive protein, CRP and interleukin-6, IL-6), respectively. RESULTS: Hierarchical regression analyses (controlling for sex, age and the shared variance of risk and resilience factors) showed that (i) cognitive depression was significantly predicted by negative self-judgement and reduced cognitive empathy; (ii) abundance of Lactobacillus spp. was directly related to positive self-judgement but only indirectly to cognitive depression and lower affective empathy (both through self-judgement); and (iii) CRP was the strongest predictor of reduced cognitive empathy, with suppression effects seen for age (negative) and IL-6 (positive) after controlling for CRP. CONCLUSIONS: Findings suggest that lactobacilli and inflammation may be differentially associated with mood disorder via brain mechanisms underpinning self-judgement and cognitive empathy, respectively. Further trials investigating interventions to increase Lactobacillus spp. in depression would benefit from direct measures of self-judgement and affective empathic distress, whilst those that aim to reduce inflammation should investigate cognitive empathy.

RESUMEN

BACKGROUND: It is believed that treatment with low temperature can reduce pain perception in chronic pain patients, including chronic low back pain patients. AIM: To evaluate the effects of a two-week repeated intervention of -67 °C cryo-chamber in patients with chronic low back pain. DESIGN: A prospective randomized double blind study design. SETTING: Hospital-based outpatients department POPULATION: Outpatients with chronic low back pain. METHODS: Comparing intervention group (-67 °C) with higher temperature (-5 °C) which was supposed as a control group in a cryo-chamber. RESULTS: Similar effectiveness in pain reduction in both intervention and control groups CONCLUSION: Cryochamber therapy with -67 °C is not superior to (sham cryo chamber) with -5 °C. CLINICAL REHABILITATION IMPACT: Cryo chambers therapy show positive effect by improving pain. For the treatment, -5 °C seems to be sufficient for these patients.

RESUMEN

The purpose of the present study was to assess the effect of a high-gluten diet against a gluten-free diet on learning stimulus-response relationships in rats. In the first phase of training rats learned to associate a stimulus light with responding on a particular response lever. In the second phase, the same rats were exposed to new, but redundant stimuli to guide responding (a tone and houselight). Probe trials, involving only new stimuli, revealed that rats fed a gluten-free diet displayed a "blocking" effect. That is, gluten-free rats did not learn to associate these new stimuli with particular responses. In contrast, high-gluten rats very quickly learned to use these redundant stimuli to guide responding. Subsequent phases of training demonstrated, however, that this group difference could be removed. The present findings are discussed in the context of the possible links between dietary gluten and schizophrenia.

RESUMEN

PURPOSE: To determine CT findings in the external, middle, and inner ear of patients with microtia and external auditory canal dysplasia. METHODS: We used high-resolution CT, with multiplanar or axial 1-mm continuous sections, coronal or sagittal reformations, or low-dose spiral acquisitions, to examine 184 temporal bones of children with microtia. RESULTS: In cases of minor microtia, auditory canal stenosis was the most common associated abnormality; in those with major microtia, atresia was predominant. Middle ear malformations depended on the severity of the auricular anomalies. Inner ear changes could also be noted. Ossicle dysplasias occurred in 98% of patients (stapes, 72%), absence of the oval window in 36%, labyrinthine malformations in 13%, closed round window in 6%, facial canal displacement in up to 75%, and aberrations of the vascular canal in 38% of patients with third-grade auricular deformity. CONCLUSION: A variety of external, middle, and, less frequently, inner ear changes were detected in connection with microtia.

RESUMEN

A case is described of a young male who suffered head injuries in a motor accident and subsequently displayed a severe anterograde amnesia in the presence of a relatively intact retrograde memory. He also demonstrated marked impairment of general intellectual ability, naming, perceptual skills and executive functioning. This case demonstrates a striking dissociation between anterograde and retrograde memory. Moreover the retention of retrograde memory in the face of such severe and global cognitive impairment accentuates the dissociation or isolability of retrograde memory. It is further argued that while frontal impairment occurred in this case it lacks any of the hallmarks of frontal amnesia. The case is further evidence for the fractionation of amnesic syndromes.

RESUMEN

The aim of this multicentre, randomized study was to compare the efficacy and safety of moxifloxacin (BAY 12-8039), a new 8-methoxy fluoroquinolone, with that of cefuroxime axetil for the treatment of acute bacterial sinusitis in adults. Diagnosis was made on a range of clinical signs and symptoms combined with radiology and microbiology. A 400 mg dose of moxifloxacin was administered once daily for 7 days to 242 patients and 250 mg twice daily of cefuroxime axetil was administered to 251 patients for 10 days. The clinical success rate at the end of treatment in the evaluable population was significantly higher (96.7%) in the moxifloxacin group (204/211) than in the cefuroxime axetil group (204/225, 90.7%; 95% confidence intervals 1.5%; 10.6%). At follow-up the success rate in the moxifloxacin group was 90.7% and that for the cefuroxime axetil group was 89.2% (95% confidence intervals -4.3%; 5.4%). The predominant pathogens isolated were Streptococcus pneumoniae and Haemophilus influenzae, followed by Moraxella catarrhalis and Staphylococcus aureus. The bacteriological eradication rates were higher for moxifloxacin (94.5%, 103/109) than for cefuroxime axetil (83.5%, 96/115; 95% CI 3.6%; 19.7%). Only one S. pneumoniae infection persisted following moxifloxacin therapy in contrast with three in individuals on cefuroxime axetil. There were slightly more adverse events in the moxifloxacin group than in the cefuroxime axetil group, but there were fewer serious adverse events following moxifloxacin treatment (three vs. eight). The drug was discontinued because of adverse events in 14 moxifloxacin patients and in 11 cefuroxime axetil patients. Overall, in all assessments, moxifloxacin was at least as effective clinically and bacteriologically, and as well tolerated, as cefuroxime axetil in the treatment of acute sinusitis.

RESUMEN

This study investigated young and older adults' conceptions of memory failure in others. One hundred young and 100 older adults rated memory failures in targets of 20, 40, 60, and 80 years of age as to how likely the memory failures were due to lack of effort or lack of ability. With increasing age, targets' forgetful episodes were rated as less likely to be caused by lack of effort and more likely to be due to lack of ability. A Subject Age x Target Age interaction on ability ratings showed age to be more salient for older subjects. Memory content, type of memory, subject sex, and target sex all influenced judgment of memory failure. The results support Erber's (1989) notion of a double standard in memory-failure appraisal; they demonstrated that adults' conceptions of memory include a decremental view of memorial ability with increasing age that is differentially sensitive to subject, target, and memorial variables.
