Objective : Several modalities are available for volumetric measurement ofthe intracranial aneurysm. We discuss the challenges involved in manualsegmentation, and analyze the application of alternative methods usingautomatic segmentation and geometric formulae in measurement of aneurysmvolumes and coil packing density. Methods : The volumes and morphology of 38 aneurysms treated withendovascular coiling at a single center were measured using three-dimensionalrotational angiography (3DRA) reconstruction software using automaticsegmentation. Aneurysm volumes were also calculated from theirheight, width, depth, size of neck, and assumed shape in 3DRA imagesusing simple geometric formulae. The aneurysm volumes were dichotomizedas "small" or "large" using the median volume of the studied population(54 mm3) measured by automatic segmentation as the cut-off valuefor further statistical analysis. Results : A greater proportion of aneurysms were categorized as being"small" when geometric formulae were applied. The median aneurysm volumesobtained were 54.5 mm3 by 3DRA software, and 30.6 mm3 usingmathematical equations. An underestimation of aneurysm volume with aresultant overestimation in the calculated coil packing density (p = 0.002)was observed. Conclusion : Caution must be exercised in the application of simple geometricformulae in the management of intracranial aneurysms as volumesmay potentially be underestimated and packing densities falsely elevated. Future research should focus on validation of automatic segmentation involumetric measurement and improving its accuracy to enhance its applicationin clinical practice.

Background The mandible is an important structure that is located in the lower third of the face. Large mandibular defects after tumor resection cause loss of its function. This study assessed the outcomes and tumor recurrence after immediate mandibular reconstruction using a free fibula osteocutaneous flap following radical resection of ameloblastoma. Methods This is a retrospective non-randomized study of outcomes and tumor recurrence of all patients diagnosed with mandibular ameloblastoma from August 1997 until August 2017 (20 years) requiring free fibula osteocutaneous flap reconstruction at a single institution. The patients were identified through an electronic operative database; subsequently, their medical records and photo documentation were retrieved. Results Twenty-seven patients were included in this study. Eighteen patients were male, while nine were female. The majority of the patients (48.1%) were in their third decade of life when they were diagnosed with ameloblastoma. All of them underwent radical resection of the tumor with a surgical margin of 2 cm (hemimandibulectomy in cases with a large tumor) and immediate mandibular reconstruction with a free fibula osteocutaneous flap. Two patients required revision of a vascular anastomosis due to venous thrombosis postoperatively, while one patient developed a flap recipient site infection. The flap success rate was 100%. There was no tumor recurrence during a mean follow-up period of 5.6 years. Conclusions Mandibular ameloblastoma should be treated with segmental mandibulectomy (with a surgical margin of 2 cm) to reduce the risk of recurrence. Subsequent mandibular and adjacent soft tissue defects should be reconstructed immediately with a free fibula osteocutaneous flap.

In today’s volatile, uncertain, complex and ambiguous environment, organizational resilience is a strategic capability to stay afloat “stormy waters” when faced with business disruptions that have grave impacts on the organization’s business operations, supply chain, and reputation. A true resilient organization needs to be constantly scanning for potential threats, identify the probable risks, plan and be prepared to deal with the consequences and impacts when the risks materialize. However, many organizations approached this capability in varied methodologies with some focusing on business continuity while others are emphasizing on crisis management. This paper uncovers the converging domains-interplays between the concepts and the building blocks of enterprise risk and resource management, emergency and crisis management, business continuity and disaster recovery management to act as the bedrock to achieve business resilience through the Incident Management Body of Knowledge as the amalgamated framework for total resilient capability; using the Adaptive Incident Management Methodology, to enable organizations to build an “Adaptive System: Integrated Approach, Dynamic Response” to the management of all-risks and all-hazards incidents.

Use of microwave and pulsed electric field (PEF) technologies for optimization of polyphenol extraction from defatted flax seed cake was attempted using a Box-Behnken response surface design. Polyphenols were extracted after microwave or PEF treatments using ultrasound under fixed variables of 200 W of ultrasonic power, a 70℃ water bath, and 20 min of extraction time. Measured responses were total phenolic and total flavonoid contents, and 2,2,-diphenyl-1-picrylhydrazyl radical (DPPH·) scavenging activity and ferric reducing/antioxidant power activities. Maximum yields of all responses were achieved under optimum conditions for microwave processing=5 min, a liquid to solid ratio=6, and at 644 W, and for PEF-assisted extraction for 30 V at 30 Hz with a 10% ethanol concentration, and a treatment time=10 s. Under optimized microwave or PEF processing conditions, yields of polyphenols from defatted seed cake were maximized.
