Unlike the first and second waves of COVID-19 pandemic in Thailand which were limited among certain populations in certain areas, the third wave starting in April 2021 spread nationwide. It was from less than 10 new cases a day in 2020, to be around 2,000 a day in June and then more than 20,000 new cases a day in August 2021. Among four doctors who were killed by COVID-19 during this third wave in Thailand, the Royal College of Radiologists of Thailand lost a very active and warm member, Associated Professor Wilaiwan Bhothisuwan. When hospitals and field hospitals were full, now COVID-19 infected patients were cared in community isolation centers. Home isolation, the last and probably the final form of health care, was set in this August. The Royal College of Radiologists of Thailand had launched a project “RadioVolunteer” to interpret and report chest radiographs of COVID-19 patients in prisons, field hospitals where there were shortage of radiologists, some community isolation centers, and radiographic units for patients with home isolation.

In the North Pacific Ocean, the Emperor Seamounts are named for Japanese emperors. A new species of dumbo octopus (‘dumbo’ because its paired fins remind one of the ears of Disney’s flying elephant; National Geographic video of dumbo octopus: www.youtube.com/watch?v=pl4pqu5FTaI&ab_channel= NationalGeographic) found there is proposed to have the English name ‘Emperor dumbo’. In the language of the German scientists who describe this new octopus, the name would be ‘Kaiserdumbo’.

RadioVolunteer, a project launched by the Royal College of Radiologists of Thailand, combinedsocial, technological and management innovation, and integrated government, private and non-profit sectors, to overcome a complex task that only one sector could not seamlessly complete. Working on a digital platform which allowed radiologist volunteers from any part of Thailand to promptly read and report chest radiographs of patients with corona virus disease 2019 (COVID-19) who resided in prisons across the country. Its digitized reporting format helped triage patients with Covid-19 pneumonia, and also screen for tuberculosis.

Objective: Radiation detectors are key components that ensure the accuracy and performances of dosimetry equipment. The study is aimed to compare the mean entrance surface air kerma (ESAK) between a DCT-10mm ionization chamber (IC) and MTS-N (LiF: Mg, Ti) chips when both detectors are exposed to ≤ 5mGy with a 10 by 10 field size, with an X-ray source and to determine the accuracy of the Thermoluminescent (TL) chips. Also, the dose will be compared to similar studies. Materials and Methods: A functional, Digital Radiography (DR) X-ray System was used. A DCT-10mm ionization chamber (IC) and an XR Multidetector was positioned at a Source to Image Distance (SID) of 100cm on polystyrene, about 20cm thick. An X-ray spectrum generated at a Practical Peak Voltage (PPV) of 60-107kV with Half Value Layer (HVL) of 2.4-4.3mmAl and filtration > 3mmAl was used. The same setup was used for the MTS-N chips. Results: The mean doses for 1-5 mGy with the MTS-N chips were 1.07±0.07, 1.60±0.13, 2.23±0.11, 2.58±0.07 and 3.45±0.10 mGy respectively, with accuracies of 7, 20, 26, 36 and 31%. Dose accuracy at 1and 2mGy was within 25% respectively. Dose accuracies at 3, 4 and 5mGy was within >25%. The correction factor for 1-5mGy was 0.94, 1.25, 1.35, 1.55 and 1.45 respectively. Conclusion: Validation of the MTS-N chips with the reference ionization chamber to this study was within 36%. The Radiation and Nuclear Safety Authority (STUK) recommends that ESAK be within 25% for entrance surface dose. ESAK accuracy mostly increased with dose as observed in this study.

Amyloidosis is a rare disease characterised by abnormal amyloid protein deposition within the affected tissue. About 37% of the patients were presented with systemic amyloidosis, of which hilar, mediastinal, and para-aortic lymph nodes were involved. Deposition of amyloid protein in the mesenteric lymph node is rarely documented, but when reported, it is seen in isolated or secondary amyloidosis. Despite an indistinguishable imaging appearance of the amyloid- deposit mesenteric node from malignancy, infection, and an inflammation process, the radiologists should be aware of variable imaging findings to be suspicious of amyloidosis. We reported a rare case of systemic amyloidosis with mesenteric node involvement, manifested as node enlargement.
