Hospital recovery following Thermachoice ablation is not dependent on setting (outpatient or daycase) or rescue analgesia: unexpected result

BACKGROUND: Thermal balloon endometrial ablation (TBEA) is increasingly being performed in the outpatient setting under local anaesthesia (LA) rather than in a daycase setting under general anaesthesia (GA). Our aim was to compare the post operative rescue analgesia requirements and duration of hospital stay in women undergoing outpatient (LA) and daycase (GA) TBEA. METHODS: Prospective observational study of consecutively recruited women who underwent outpatient (LA) TBEA (n=51) and daycase (GA) TBEA (n=50) over the same time period. Analgesia that was provided additional to the standard administered analgesic regimen was considered rescue analgesia. The main outcome measures were requirement for rescue analgesia and duration of hospital stay in both cohorts. RESULT(S): LA compared to GA cohorts had shorter hospital stays (11h [95% CI 9-13] vs. 17h [95% CI 14-20]) and lower analgesia requirements. However, multivariate regression, correcting for all known confounders, showed that duration of stay was independent of setting for ablation or amount of rescue analgesia. CONCLUSION(S): Duration of hospital stay is not entirely dependent on whether outpatient or daycase endometrial ablation is considered. This unexpected preliminary finding deserves to be validated in future confirmatory trials that compare outpatient and daycase treatments. We also discuss the confounding factors that should be considered when designing such trials.     

On the Morphological Deviation in Additive Manufacturing of Porous Ti6Al4V Scaffold: A Design Consideration

Additively manufactured Ti scaffolds have been used for bone replacement and orthopaedic applications. In these applications, both morphological and mechanical properties are important for their in vivo performance. Additively manufactured Ti6Al4V triply periodic minimal surface (TPMS) scaffolds with diamond and gyroid structures are known to have high stiffness and high osseointegration properties, respectively. However, morphological deviations between the as-designed and as-built types of these scaffolds have not been studied before. In this study, the morphological and mechanical properties of diamond and gyroid scaffolds at macro and microscales were examined. The results demonstrated that the mean printed strut thickness was greater than the designed target value. For diamond scaffolds, the deviation increased from 7.5 μm (2.5% excess) for vertical struts to 105.4 μm (35.1% excess) for horizontal struts. For the gyroid design, the corresponding deviations were larger, ranging from 12.6 μm (4.2% excess) to 198.6 μm (66.2% excess). The mean printed pore size was less than the designed target value. For diamonds, the deviation of the mean pore size from the designed value increased from 33.1 μm (−3.0% excess) for vertical struts to 92.8 μm (−8.4% excess) for horizontal struts. The corresponding deviation for gyroids was larger, ranging from 23.8 μm (−3.0% excess) to 168.7 μm (−21.1% excess). Compressive Young’s modulus of the bulk sample, gyroid and diamond scaffolds was calculated to be 35.8 GPa, 6.81 GPa and 7.59 GPa, respectively, via the global compression method. The corresponding yield strength of the samples was measured to be 1012, 108 and 134 MPa. Average microhardness and Young’s modulus from α and β phases of Ti6Al4V from scaffold struts were calculated to be 4.1 GPa and 131 GPa, respectively. The extracted morphology and mechanical properties in this study could help understand the deviation between the as-design and as-built matrices, which could help develop a design compensation strategy before the fabrication of the scaffolds.     

Unusual metastases from esophageal carcinoma: computed tomography demonstration

The computed tomography findings of large subcutaneous metastatic implants in the pelvic and inguinal regions from an epidermoid carcinoma of the esophagus are presented. To the best of the authors' knowledge, this appearance has not previously been reported.     

Twisting of peripheral balloon appearing as a non-dilating peroneal artery lesion

Peripheral arterial lesions are usually longer than coronary artery lesions and require longer balloons and stents. Theoretically while advancing a long balloon in a long, high grade lesion with aggressive manipulation, the balloon can twist inside the lesion, but this has not been described before in the literature. Herein we are reporting a case where peripheral balloon (PB) twisted and appeared as a non-dilating lesion.     

Brain responses to stimuli mimicking dental treatment among non‐phobic individuals: A meta‐analysis

Numerous neuroimaging studies have attempted to identify how the brain responds to stimuli mimicking dental treatment in normal non‐phobic individuals. However, results were sometimes inconsistent due to small sample sizes and methodological variations. This meta‐analysis employs standardized procedures to summarize data from previous studies to identify brain regions that were consistently activated across studies, elicited by stimuli such as pictures, sounds, or audiovisual footage mimicking those encountered during dental treatments. A systematic literature search was carried out using PubMed and Scopus. The meta‐analysis analyzed data from 120 healthy subjects from seven neuroimaging studies. We assessed the risk of bias among the included studies with the Risk of Bias Assessment Tool for Nonrandomized Studies. One study appeared to have a high risk of selection bias, whereas the others were considered to have a low risk of bias. Results revealed three clusters of activation with cluster sizes ranging from 768 mm³ to 1,424 mm³. Stimuli mimicking dental treatment consistently activated the bilateral anterior insula; right dorsal anterior cingulate, putamen, and medial prefrontal cortex; and left claustrum. This study confirmed that audio and/or visual stimuli mimicking dental treatment consistently activated the fear‐related brain regions among healthy subjects, mostly consistent with activations from general anxiety but without the involvement of the amygdala.     

Psychosis and Seizure Disorder: Challenges in Diagnosis and Treatment

Bipolar disorder is associated with high mortality, and people with this disorder on average may die 10–20 years earlier than the general population. This excess and premature mortality continues to occur despite a large and expanding selection of treatment options dating back to lithium and now including anticonvulsants, antipsychotics, and evidence-based psychotherapies. This review summarizes recent findings on mortality in bipolar disorder, with an emphasis on the role of suicide (accounting for about 15 % of deaths in this population) and cardiovascular disease (accounting for about 35–40 % of deaths). Recent care models and treatments incorporating active outreach, integrated mental and physical health care, and an emphasis on patient self-management have shown promise in reducing excess mortality in this population.
