MB2 in maxillary second molar.   总被引:1,自引:0,他引:1  
Occurrence of the second mesiobuccal canal (MB2) is a frequent finding. Literary reports have shown it to be found more in the cases of the maxillary first molar. However the maxillary second molars have also been found with this variation in a number of canals. This paper presents a case report on the occurrence of a second mesiobuccal canal or the MB2 in the maxillary second molar.  相似文献

Targeted muscle reinnervation (TMR) was initially designed to provide cortical control of upper limb prostheses through a series of novel nerve transfers. Early experience has suggested that TMR may also inhibit symptomatic neuroma formation. We present the first report of TMR performed at the time of a traumatic shoulder disarticulation. The procedure was done to prevent painful neuroma pain and allow for myoelecteric prosthetic use in the future. Eight months post-operatively, the patient demonstrates multiple successful nerve transfers and exhibits no evidence of neuroma pain on clinical exam. Using the Patient Reported Outcomes Measurement Information System (PROMIS), the patient demonstrates minimal pain interference or pain behavior. Targeted muscle reinnervation may be considered in the acute trauma setting to prevent neuroma pain and to prepare patients for myoelectric prostheses in the future.  相似文献

Background: To analyse the disability status of elderly Taiwanese dementia patients by using the World Health Organisation Disability Assessment Schedule 2.0 (WHODAS 2.0). Methods: We enrolled 12 126 disabled elderly (>65 years) patients with dementia during July 2012–January 2014 from the Taiwan Data Bank of Persons with Disability. Trained interviewers evaluated the standardised scores in the six WHODAS 2.0 domains. Student’s t test was used for comparing WHODAS 2.0 scores of male and female dementia patients with different age groups. Results: The study population comprised 12 126 patients; 7612 were women and 4514 were men. The WHODAS 2.0 scores showed that the dementia patients had global activity limitation and participation restriction in all domains. Dementia-induced disability was prominent in male patients in all of the domains of the WHODAS 2.0. The domains of life activities, getting along with people and cognition were more strongly affected than the other domains. However, women experienced more rapid functional decline than men did as they aged. Conclusion: The data analysed in this large-scale, population-based study revealed crucial information on dementia-induced disability in elderly patients on the basis of the WHODAS 2.0 framework.
  • Implications for rehabilitation
  • Dementia patients have global functional disability in all domains of WHODAS 2.0 and multidisciplinary team is needed for rehabilitation programme intervention for these patients.

  • When considering the rehabilitation resource and strategy, the domains of cognition, activities of daily living and life activities should be focussed.

  • When dementia patients aged 65–75 years old, male patients got more restriction of function than female and more medical resource allocation for disabled male patients is recommended.

  • With ageing, female dementia patients exhibited more rapid functional decline than male patients did and more budget about rehabilitation for maintain functional and dementia progression is crucial for female patients.

Context

Employment rates in individuals with spinal cord injury (SCI) are approximately 35%, which is considerably lower than that of the general population. In order to improve employment outcomes a clear understanding of what factors influence employment outcomes is needed.

Objective

To systematically review factors that are consistently and independently associated with employment outcomes in individuals with SCI, and to understand the magnitude of their influence.

Methods

Through an electronic search of MEDLINE/PubMed, EMBASE, CINAHL, PsycINFO, Social Science Abstracts and Social Work databases, we identified studies published between 1952–2014 that investigated factors associated with employment outcomes following SCI. Exclusion criteria included: (1) reviews (2) studies not published in English (3) studies not controlling for potential confounders through a regression analysis, or (4) studies not providing an effect measure in the form of OR, RR, or HR. Data were categorized based on the International Classification of Functioning, Disability and Health framework, with each domain sub-categorized by modifiability. First author, year of publication, sample size, explanatory and outcome variables, and effect measures were extracted.

Results

Thirty-nine studies met the inclusion criteria. Twenty modifiable and twelve non-modifiable factors have been investigated in the context of employment following SCI. Education, vocational rehabilitation, functional independence, social support, and financial disincentives were modifiable factors that have been consistently and independently associated with employment outcomes.

Conclusion

A number of key modifiable factors have been identified and can inform interventions aimed at improving employment outcomes for individuals with SCI. Future research should focus on determining which factors have the greatest effect on employment outcomes, in addition to developing and evaluating interventions targeted at these factors.  相似文献
