Archaeometric analyses of the stuccoes and polychromy on temple C at Selinunte (Sicily)
Authors: Lazzarini Lorenzo , D’Ignoti Katia , Alfano Giovanni , Cancelliere Stefano , Bennardo Carmelo 
Published: September 2020

The most recent restoration of the re-erected part of temple C of ancient Selinus (modern Selinunte, Sicily) made it possible to carry out direct observations and a sampling campaign on the very few extant ancient stuccoes and polychromy traces on the columns and capitals of the northern peristasis. The samples were submitted to laboratory analyses including XRD on powder, OM, as well as SEM-EDS, on polished and thin sections, providing a stratigraphic reconstruction of the various stuccoes applied over the biocalcarenite of the temple. The composition of the stuccoes, together with that of the remaining polychromy, has been determined archaeometrically, thus allowing new hypotheses about the decorative materials and techniques used during the main lifetime (6th-5th centuries B.C.) of the temple.
La peinture sur les sols de mortier et les mosaïques d’époque hellénistique : modes d’emploi d’une polychromie architecturale largement méconnue
Authors: Guimier-Sorbets Anne-Marie 
Published: September 2020

En nous fondant sur des pavements découverts en Macédoine, à Rhodes, à Délos, à Alexandrie et dans quelques autres sites du monde grec, nous nous attacherons à montrer comment la polychromie a été mise en œuvre et développée sur les sols de mortier et les mosaïques à partir des ve-ive siècles avant J.-C., dans des contextes tant publics que domestiques. Le premier objectif était de décorer les sols par l’adjonction de couleurs vives pour étendre et aviver la polychromie, élément important du décor architectural grec. Le second était de copier la peinture murale ou de chevalet, art majeur de cette époque, lui-même fortement polychrome et illusionniste. En raison de l’altération de la peinture et des matériaux artificiels employés, cette polychromie n’a pas été repérée au moment de la découverte et reste en grande partie à restituer.

The paper deals with a group of Etruscan nenfro sculptures found in Tuscania (Viterbo) and kept in the Archaeological Museum of Florence, where some of them were already displayed at the end of the 19th and early 20th century. After the flood of Florence in 1966, the Museum was heavily damaged, causing the dismemberment of many contexts, including those from Tuscania. The artefacts were then cleaned, restored and most of them were moved into the depository of the Museum and to the Villa Corsini, where they are currently kept. The sculptures were analysed by means of a totally non-invasive analytical protocol through imaging and single spot analysis. Traces mostly of yellow and red iron-based pigments for the skin tone as well as few traces of Egyptian blue were evidenced. The comparison of the obtained analytical results joined with the archaeological studies has provided new information about the sculptures, their conservation state and artistic technique as well as deepened the knowledge about their original contexts.
“Reconstruction” of the polychromy of ancient sculpture: a necessary evil?
Authors: Østergaard Jan Stubbe 
Published: September 2020

The contribution offers an overview of the history of reconstructions and their use, with a representative selection of formats and their contexts, from the beginnings in the early 19th century to the present. The polychromy of ancient architecture is dealt with only to a limited degree.The point of departure is a perceived need of establishing an informed and critical discussion of the whys and wherefores of reconstructions. On the background of the investigative technologies which have been developed with unprecedented rapidity, a methodological protocol allowing cross-checks of data is recommended.
Renal cortical transit time as a predictor for pyeloplasty in pediatric patients with unilateral hydronephrosis
Authors: More Stuart , Lazarus John , Brink Anita 
Published: September 2020

AbstractMajority of patients with unilateral hydronephrosis (HN) detected on ultrasound do not require pyeloplasty. The measurement of the cortical transit time (CTT) has been demonstrated by several authors to predict the need for patients who may require pyeloplasty. The study aimed to assess if CTT would have predicted a drop in differential renal function (DRF) in patients with unilateral HN on the affected side and to assess whether CTT would differ on the first renogram between those patients who had a pyeloplasty and those who did not have a pyeloplasty. Sixty-eight patients with at least two renograms with unilateral HN with a normal contralateral kidney were observed retrospectively. The CTT was recorded for each kidney. Renograms were processed three times to measure the DRF. The mean of the three DRF measurements was used for analysis. The mean CTT of the left and right hydronephrotic kidneys was 6.0 min and 6.7 min, respectively. The relationship between CTT and DRF as well as CTT and anterior posterior diameter in the first renogram of those patients who did not have a pyeloplasty was statistically significant (P < 0.05). In the 20 patients who had a pyeloplasty, there was a drop of more than 10% in the DRF of three patients. No significant difference was found in CTT or DRF when comparing the group who had surgery against the group who did not have surgery. The current study was unable to demonstrate in our series of patients that CTT can predict a drop in DRF in those patients who would require pyeloplasty.

Published: September 2020

AbstractProstate-specific membrane antigen (PSMA)-targeted imaging is now an effective tool for the evaluation of prostate cancer patients. Although salivary glands take up 68Ga-PSMA avidly, pathologies of these glands may be readily noticeable. Herein, we present a case of prostate cancer referred for 68Ga-PSMA positron emission tomography—computed tomography in whom an isolated aplasia of the submandibular salivary gland was incidentally found.
Comparison of posttherapy 90Y positron emission tomography/computed tomography dosimetry methods in liver therapy with 90Y microspheres
Authors: Knesaurek Karin 
Published: September 2020

AbstractThe aim of our study was to compare dosimetry methods for yttrium-90 (90Y) positron emission tomography/computed tomography (PET/CT). Twenty-five patients were taken to a PET/CT suite following therapy with 90Y microspheres. The low mA, nondiagnostic CT images were used for attenuation correction and localization of the 90Y microspheres. The acquisition time was 15 min, the reconstruction matrix size was 200 mm × 200 mm × 75 mm, and voxel size was 4.07 mm × 4.07 mm × 3.00 mm. Two software packages, MIM 6.8 and Planet Dose, were utilized to calculate 90Y dosimetry. Three methods were used for voxel-based dosimetry calculations: the local deposition method (LDM), LDM with scaling (LDMwS) for known injected activity, and a dose point kernel (DPK) method using the MIRD kernel. Only the DPK approach was applied to the Planet Dose software. LDM and LDMwS were only applied to the MIM software. The average total liver dosimetry values (mean ± standard deviation) were 60.93 ± 28.62 Gy, 53.59 ± 23.47 Gy, 55.33 ± 24.80 Gy, and 54.25 ± 23.70 Gy for LDMwS, LDM, DPK with MIM, and DPK with Planet Dose (DOSI), respectively. In most cases, the LDMwS method produced slightly higher dosimetry values than the other methods. The MIM and Planet Dose DPK dosimetry values (i.e., DPK vs. DOSI) were highly comparable. Bland–Altman analysis calculated a mean difference of 1.1 ± 2.2 Gy. The repeatability coefficient was 4.4 (7.9% of the mean). The MIM and Planet Dose DPK dosimetry values were practically interchangeable. 90Y dosimetry values obtained by all methods were similar, but LDMwS tended to produce slightly higher values.

Authors: Shah Digish , Odedara Prakash 
Published: September 2020

AbstractCutaneous malignant melanoma (MM) metastases to prostate and spleen are very rarely experienced in clinical setting. As per our knowledge, coexistence of prostate and splenic metastatic MM is not reported worldwide. We are presenting a case of 70-year-old male patients with biopsy and clinically proven case of multifocal cutaneous malignant melanomatous lesions having multiple metastatic lymph nodes and systemic metastases, including prostate and spleen. This is the first case reported worldwide having a combination of prostate and splenic metastases.
Inferior vena cava syndrome on skeletal scintigraphy secondary to metastatic prostate cancer
Authors: Makusha Lovemore , Kulon Michal , Pucar Darko , Young Colin 
Published: September 2020

AbstractThis interesting image illustrates an unusual case of inferior vena cava (IVC) syndrome from prostate cancer retroperitoneal adenopathy initially identified with skeletal scintigraphy. IVC syndrome is an infrequent occurrence resulting from extrinsic compression or intraluminal occlusion of the vessel. Whole-body planar skeletal scintigraphy showed a stable left sacroiliac metastasis and increased soft tissue uptake throughout the lower hemibody up to the lower chest level. Computed tomography (CT) demonstrated extrinsic compression of the IVC from metastatic retroperitoneal adenopathy. This represents a rare presentation of IVC syndrome in prostate cancer with characteristic appearance on skeletal scintigraphy of Fisherman's Wader's sign, that should prompt confirmatory anatomic imaging.

Published: September 2020

AbstractPositron-emission tomography-magnetic resonance imaging (PET-MRI) is an emerging hybrid imaging modality that utilizes the superior soft tissue resolution of MR with the metabolic data from PET. In this study, we sought to assess the clinical value of fluorodeoxyglucose (FDG) PET-MRI with dedicated pelvic PET-MR in the initial staging of cervical cancer. In this institutional-approved study, we identified 23 adult females who underwent FDG PET-MRI on hybrid camera for staging of primary uterine cervical cancer that included a dedicated PET-MR of the pelvis. A nuclear medicine physician and a radiologist reviewed the PET, MRI, and fusion-body and pelvis images alone and then with consensus read characterizing PET and MR abnormal findings. There were 23 patients who underwent FDG PET-MRI for initial staging of cervical cancer with an average age of 52.2 ± 14.0 years. A total of 23 suspected lymph nodes in eight different patients were detected within the pelvis with increased metabolic activity on PET. Both the dedicated pelvis and whole-body PET imaging detected the same corresponding pelvic lymph nodes, although the pelvic PET imaging had better lymph node uptake delineation due to longer acquisition time. Using a 10-mm short-axis criterion, MRI identified only 43.5% of the FDG avid lymph nodes. The average SUVmax on the pelvis PET sequences was higher with SUV 8.9 ± 5.2 compared to the whole-body PET with SUV 7.8 ± 5.4 but was not statistically significant (P > 0.05). Primary cervical cancer was identified in 18 patients on both PET imaging and MRI with dedicated MR pelvis providing better characterization. Based on our results of the patients with cervical cancer evaluated for initial staging, combining dedicated pelvic PET-MRI with whole-body PET/MR provides the most complete status of malignant disease in reference to delineation of primary tumor, involvement of surrounding tissues, and regional lymph nodes.

AbstractAbnormal beta-amyloid plaques and tau protein accumulation are the core pathologic features of Alzheimer's disease. However, the accumulation of these proteins is also common in cognitively normal elderly people. Therefore, this study is aimed to evaluate the amyloid and tau accumulation in the cognitively normal population. A preliminary prospective study was conducted on 24 cognitively normal individuals who underwent Pittsburgh compound B (11C-PiB) and 18F-THK 5351 positron emission tomography (PET)/computed tomography scans. The standardized uptake value ratio (SUVR) was used for quantitative analysis of the two tracers and comparisons between two age groups: 60 years and >60 years. Co-registration was applied between the dynamic acquisition PET and T1-weighted magnetic resonance imaging to delineate various cortical regions. P-mod software with the automated anatomical labeling-merged atlas was employed to generate automatic volumes of interest for different brain regions. The posterior cingulate versus precuneus SUVRs of PiB uptake was 1.40 ± 0.07 and 1.38 ± 0.22 versus 1.17 ± 0.07 and 1.14 ± 0.18 in those aged ≤60 years and >60 years, respectively, whereas the SUVRs of THK5351 retention at brain stem versus inferior temporal SUVRs were 1.84 ± 0.06 and 1.91 ± 0.18 versus 1.37 ± 0.04 and 1.48 ± 0.21 in the age groups of ≤60 years and >60 years, respectively (P = 0.20). Our findings allow the determination of the preliminary optimal cutoff points for SUVRs in amyloid and tau PET studies. Ultimately, these values can be applied to normal databases in clinical use to improve quantitative analysis.

Published: September 2020

AbstractIn this study, we have proposed and validated that histogram of a good-quality bone scan image can enhance a poor-quality bone scan image. The histograms of two good-quality technetium-99m methyl diphosphonate bone scan images IAand IBrecommended by nuclear medicine physicians (NMPs) were used to enhance 87 poor-quality bone scan images. Processed images and their corresponding input images were compared visually by two NMPs with scoring and also quantitatively using entropy, Structural similarity index measure, edge-based contrast measure, and absolute brightness mean error. Barnard's unconditional test was applied with a null hypothesis that the histogram of both IAand IBproduces similar output image at α =0.05. The mean values of quantitative metrices of the processed images obtained using IAand IBwere compared using Kolmogorov—Smirnov test. Histogram of a good-quality bone scan image can enhance a poor-quality bone scan image. Visually, histogram of IBimproved statistically significantly higher proportion (P < 0.0001) of images (86/87) as compared to histogram of IA(51/87). Quantitatively, IBperformed better than IA,and the Chi-square distance of input and IBwas smaller than that of IA. In addition, a statistically significant (P < 0.05) difference in all the quantitative metrics among the outputs obtained using IAand IBwas observed. In our study, reference histogram of good-quality bone scan images transformed the majority of poor-quality bone scan images (98.85%) into visually good-quality images acceptable by NMPs.

AbstractFollicular thyroid carcinoma (FTC) is the second most common cancer of the thyroid, after papillary carcinoma. Oral metastasis arising from FTC is very rare. Mandible is more commonly affected than maxilla, with the premolar—molar region being the most frequent site of metastasis. We present the case of a 68yearold female, with swelling in the region of the parotid gland, complaining of periodic rightsided pain in the temporomandibular joint, which occurred most often in the morning with numbness and pain, and difficulty in opening the mouth. After ultrasound and X-ray, the patient was operated and the pathohistological finding was in favor of metastasis of FTC. After 3 months, a total thyroidectomy was performed, and FTC was detected in the right thyroid lobe. Laboratory results were as follows: FT4 = 9.92 pmol/L, thyroid-stimulating hormone = 9.9 mIU/L, and hTG >300 μg/L. Bone scan showed no bone metastasis. Radioablation with 131I of 150 mCi was given to the patient, followed by substitutional therapy with levothyroxine. Mandible metastasis as a single skeletal deposit from follicular thyroid carcinomas is a rare clinical finding. Maxillofacial surgeons should consider and rule out thyroid pathology before performing operation of tumor formation in the mandible region. If feasible, surgical-based treatment options offer the best survival outcomes.

Published: September 2020

AbstractWhole-body 18F-fluorodeoxyglucose positron emission tomography (PET) has been used extensively in the last decade for the primary staging and restaging and to assess response to therapy in these patients. We aim to discuss the diagnostic performance of PET/computed tomography in the initial staging of breast carcinoma including the locally advanced disease and to illustrate its role in restaging the disease and in the assessment of response to therapy, particularly after the neoadjuvant chemotherapy. Causes of common pitfalls during image interpretations will be also discussed.

Published: September 2020

Traditional Balinese architecture is a regional architecture that needs to be preserved in this globalization era. The knowledge and implementation of Balinese architecture is also increasingly diminished as the modernity influences the building (architecture). This is followed by the presence of a present-day architectural style dominated by minimalist architecture. The application of Balinese architecture today can only be found in the application of ornaments in the building façade.
There are several types of traditional Balinese buildings that still survive until now such as Bale Dangin, Bale Meten/sakutus, Bale Dauh, Jineng/Kelumpu, Paon and others, the building is still surviving in terms of shape, function, and materials used since the first time. Bale Dangin serves as a place of ceremonies, so it is vital to the life of Balinese people who practice Hinduism. Therefore, it is necessary to do the effort to preserve and keep the cultural values of Bale Dangin.
The research on Bale Dangin was conducted based on the lack of references that discussed the Bale Dangin thoroughly. This research also aims to determine the peculiarities of the building of Bale Dangin Sakenem seen from philosophical value, ethics and ritual, and get a form of guidelines regarding the building of Bale Dangin Sakenem which can be used as reference in designing or constructing the Bale Dangin Sakenem building.
The research approach used in this research is based on qualitative descriptive research methods. Qualitative research intends to understand the phenomenon of what is experienced by research subjects such as behavior, perception, motivation, action, holistically and with descriptions in the form of words and language in a particular context that Nature and by utilizing a variety of natural methods. The method of descriptive qualitative research on this study was used to describe the facts in the field related to the condition of Bale Bale Dangin Sakenem in the case study used, judging by the function of building, form, layout, as well as Development process from the beginning until the building is ready to be occupied.
This research is expected to produce a special reference to the Bale building of the sakenem in a traditional Balinese house seen from the philosophical value, ethics and ritual and construction process. Indirectly, this can also preserve Balinese architecture that is in accordance with philosophy and meaning

Factors Affecting Cost and Patient Choice of Travel Insurance in Cardiac Disease: A Web-Based Case-Control Study
Authors: Bennett Michael , Joshi Shruti S , Denvir Martin 
Published: September 2020

Background The aim of this study was to explore variations in cost and choice of travel insurance in patients with cardiac disease. Methods Clinical data from patients with myocardial infarction (MI, n = 20), Marfan syndrome (MFS, n = 10) and dilated cardiomyopathy (DCM, n = 10) were input to insurance websites for a proposed ten-day holiday and data for premium cost (£) and choice of quotes (n) collated for each condition. Age-matched healthy individuals were used as controls. Results Median cost of insurance was significantly higher for MI (£233.07; interquartile range (IQR) = £222.95-£245.47 versus £24.29; IQR = £11.9-£34.09, p = <0.001), MFS (£37.43; IQR = £23.61-58.83 versus £19.20; IQR = £9.09-£27.31, p = 0.0378)) and DCM (£166.87; IQR = £129.71-£198.62 versus £23.96; IQR = £11.99-£32.44, p = <0.001) compared to controls. Choice of quotes was also significantly reduced for MI (5; IQR = 5-14 versus 89; IQR = 26-110, p = <0.001) MFS (61; IQR = 26-83 versus 105; 26-105, p = <0.001) and DCM (19; IQR = 16-28 versus 89; IQR = 26-106, p = <0.001) compared to controls. Modifiable factors, such as time after cardiac event or awaiting further investigations, and clinical factors, such as persistent symptoms and disease severity, lead to a significant increase in cost. Conclusions This study provides insight into the factors affecting cost and choice of travel insurance for patients with cardiac disease. The findings highlight ways in which healthcare professionals can support patients to obtain travel insurance.
