Abstract

OBJECTIVE: To contribute toward the identification of population-based clinical and histopathological profile of oral squamous cell carcinoma (OSCC), this study was undertaken at the Regional Cancer Centre of Odisha (AHRCC), India. PATIENTS AND METHODS: This retrospective study included all patients diagnosed with OSCC registered at AHRCC, Odisha from 1st January 2015 to 31st December 2018. Demographic, clinical, and pathological data of each patient were retrieved from patient records. Patients with incomplete records were excluded. No postoperative treatment details were collected. RESULTS: The study included 851 cases of OSCC with the mean age of the population found to be 53.8±14.2 years. Male to female ratio was found to be 2.18:1. Gingivobuccal complex was the most common site of OSCC. While 679 patients were reported to undergo incision biopsy only 172 patients underwent excision biopsy in four years. Well differentiation (n=782) is the most common histological grading. The median clinical size of the tumour was 4 cm. Upon analyzing histological parameters in excision specimens lymphovascular and perineural invasion were seen in 38 and 26 cases, respectively. Cervical lymph node metastasis was seen in 42 cases out of 172 excision specimens (24%). 63.23% of cases presented with a depth of invasion between 5 to 10 mm. CONCLUSIONS: This is the largest comprehensive data from the regional cancer center of Odisha population which highlights the demographic, clinical, and histopathological data reported to date.

Abstract

OBJECTIVE: Optical Coherence Tomography (OCT) is a non-invasive imaging technique that produces cross-sectional images through biological tissues, allowing three-dimensional reconstruction and analysis. Aim was to evaluate if OCT may discriminate among tissues with different bone density and composition, by measuring the depth of light penetration in porcine and rat bone samples. MATERIALS AND METHODS: Two carpal bone samples (2 cm length) were harvested from the porcine forelimb and fixed overnight in 3.7% buffered formal saline. Following fixation, one sample was decalcified in a 1:1 mixture of 8% hydrochloric acid and 8% formic acid solution for three days, with solution changes each day. Samples were imaged using an OCT microscope. Furthermore, the calvaria, ulnar, alveolar and basal bone of mandible of 6 male and 6 female rats were cleared of overlying soft tissues and scanned under OCT. The light penetration depth in each sample was measured using the software Image J, and Scattering Attenuation Microscopy. RESULTS: In the mineralized bone the average depth (µm) and standard deviation (SD) of light penetration were 790.1±18.05 and 410.4±21.7 for periosteal and endosteal surface, respectively, and 507.3±21.03 for cross-section surfaces, while it was 858.4±32.03 for periosteal surface, 1150±26.9 for endosteal, and 627.3±31.8 for cross-section bone surfaces in demineralized porcine bone. There was a significant difference (p<0.001) in depth of light penetration between normal and de-mineralized bone for all regions evaluated. No systematic significant difference in light penetration depth between-gender was found at any site evaluated, while there were variations between sites (p<0.001). The OCT detected differences in bone mineral and porosity among gender (p<0.0001) CONCLUSIONS: This study suggests that OCT may represent a valuable technique to estimate local variations in bone mineral content.

18. Spin- and charge-density excitations in quantum dots via Quantum Monte Carlo simulation

Author

Colletti, L, Pederiva, F, Lipparini, E, and Umrigar, CJ

Abstract

The calculation of the polarizability provides a method of calculating the collective-modes excitation energies of an electronic system. However, the polarizability is a correlated quantity, thus demanding a major effort when Monte Carlo methods are used for its evaluation. Nevertheless, Quantum Monte Carlo results represent the benchmark in most many-body physics. We applied a correlated Variational and Diffusion Monte Carlo scheme to a GaAs-AlGaAs quantum dot. Comparison with Raman scattering experiments and previous calculations is considerable. (c) 2007 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim.

Abstract

The electrochemical analog of atomic layer epitaxy (ALE) is being studied. ALE is a method for growing thin films of materials using a cycle of surface limited reactions. The surface limited reactions control the deposition by limited the growth to an atomic layer at a time. In electrochemistry, a surface limited deposition is generally referred to as under-potential deposition (UPD), and UPD is used to form the atomic layers in electrochemical ALE (ECALE). The work presented here is an atomic level study of the deposition of the first few monolayers of CdSe via ECALE: by the alternated UPD of atomic layers of Se and Cd on the low index planes of Au. UPD of Se resulted in the formation of ordered structures on each of the low index planes of Au, as observed by low energy electron diffraction (LEED) and scanning microscopy (STM). The subsequent UPD of Cd resulted in CdSe deposits which exhibited 1:1 stiochiometry, as determined by coulometry and Auger electron spectroscopy (AES). The following LEED patterns were observed for the CdSe monolayers: Au(111) (square root of 7 times square root of 7)Rl9.1deg2, Au(111)(3X3), Au(11O)(2X3), and the Au(100)(square root of 2 times square of 2)R45 deg. Similar LEED patterns were observed on each surface for deposits formed using up to three ECALE cycles.

Abstract

Objective:We report a rare presentation of otogenic bacterial meningitis secondary to a stapes footplate malformation in a paediatric patient with an auditory brainstem implant.Case report:A patient with Mondini's dysplasia developed meningitis six years after auditory brainstem implantation. The aetiology was believed to be otogenic, secondary to stapes footplate malformation.Conclusion:To our best knowledge, this is the first report of otogenic bacterial meningitis secondary to stapes footplate malformation in a paediatric patient with an auditory brainstem implant. Subjects with inner ear malformations, especially Mondini's dysplasia, need to be carefully evaluated pre-operatively to reduce or eliminate any anatomical conditions which may predispose to meningitis. In children with an auditory brainstem implant and suspected ear malformation, we recommend pre-operative radiological investigation to look for the ‘bulging oval window’ sign. When radiological signs are positive, bilateral exploratory tympanotomy should be performed to detect any undiagnosed anatomical stapes footplate defects, which may predispose to bacterial meningitis.
