Clinical application of 3-dimensional tissue volume assessment using CloudCompare.

Adjunctive procedures, including autologous fat grafting and surgical debulking, may be required to optimise facial contours following maxillomandibular reconstruction. A standardised method for the quantitative analysis of volumetric change and the impact of restoration of facial symmetry on health-related quality of life remains unclear. We use two case studies to illustrate the value of a combination of objective 3-dimenmsional (3D) measurements, clinical assessments, and patient-reported outcomes, using the FACE-Q questionnaire to elucidate the benefits of adjunctive procedures.

Long-term durability of uterine artery embolisation for treatment of symptomatic adenomyosis.

BACKGROUND: Failing conservative therapies, uterine artery embolisation (UAE) has been proposed as a uterine-sparing option for treatment of symptomatic adenomyosis. UAE appears effective at short-term; however long-term durability is less well established. AIMS: To evaluate the long-term clinical efficacy of UAE for treatment of adenomyosis. MATERIALS AND METHODS: One hundred and four women with initial clinical success following UAE for adenomyosis (results previously published) were further followed with a two-part online survey. Part one inquired about menopause, symptom recurrence, need for further intervention and overall satisfaction. Part two comprised the Uterine Fibroid Symptom and health-related Quality of Life (UFS-QOL) questionnaire. Maintenance of clinical success was defined as remaining 'happy' or 'very happy' with overall outcome, no recurrence of symptoms, or need for further intervention. RESULTS: Of those women with initial success, 91/104 (88%) participated in this long-term study at mean 52 months following UAE. Maintenance of clinical success was demonstrated in 82/91 (90%) women. For the remaining 9/91 (10%) women, mean time to failure was 31 months. There were 53/91 (58%) women who reached menopause at mean age of 51.5 years, occurring at mean 30 months post-UAE. UFS-QOL demonstrated significant decrease in symptom severity from 58.9 to 20.0 (P < 0.001); and significant increase in QOL from 40.3 to 86.3 (P < 0.001). CONCLUSIONS: Long-term durability of UAE for treatment of adenomyosis was demonstrated, with cumulative success rate of 80% at mean 52 months. UAE did not appear to bring forward menopause. UAE should be considered as an alternative to hysterectomy to treat adenomyosis.

Microglia show altered morphology and reduced arborization in human brain during aging and Alzheimer's disease.

Changes in microglia function are involved in Alzheimer's disease (AD) for which ageing is the major risk factor. We evaluated microglial cell process morphologies and their gray matter coverage (arborized area) during ageing and in the presence and absence of AD pathology in autopsied human neocortex. Microglial cell processes were reduced in length, showed less branching and reduced arborized area with aging (case range 52-98 years). This occurred during normal ageing and without microglia dystrophy or changes in cell density. There was a larger reduction in process length and arborized area in AD compared to aged-matched control microglia. In AD cases, on average, 49%-64% of microglia had discontinuous and/or punctate Iba1 labeled processes instead of continuous Iba1 distribution. Up to 16% of aged-matched control microglia displayed discontinuous or punctate features. There was no change in the density of microglial cell bodies in gray matter during ageing or AD. This demonstrates that human microglia show progressive cell process retraction without cell loss during ageing. Additional changes in microglia occur with AD including Iba1 protein puncta and discontinuity. We suggest that reduced microglial arborized area may be an aging-related correlate of AD in humans. These variations in microglial cells during ageing and in AD could reflect changes in neural-glial interactions which are emerging as key to mechanisms involved in ageing and neurodegenerative disease.
