COVID-19 Outbreak in Africa: Lessons and Insights from the West African Ebola Virus Disease Epidemics

Over the years, the African continent has had to battle several outbreaks of infectious diseases in different countries. Some of the most deadly were the Ebola virus disease (EVD) outbreaks that occurred in West Africa between 2014 and 2016 affecting Guinea, Liberia, and Sierra Leone and, more recently, from 2018 to 2020 in the Democratic Republic of Congo (DRC). In the era of the COVID-19 pand...

Covid-19 Serological Tests: A Journey from Denial of Reality to Conclusive Insights

In response to the outbreak of COVID-19, caused by the SARS-CoV-2 virus, several tests are needed for diagnosis of acute illness, contact tracking, diagnosis of asymptomatic infections, and assessment of herd immunity. While PCR is the standard test in acute type, serological tests have been developed and used to meet diagnostic needs due to the widespread prevalence of the disease. Unlike the...

Incidental finding of 68Ga-PSMA uptake in covid-19 induced pneumonia

A 68 years old man with prostate carcinoma was referred for 68Ga-PSMA PET/CT scan because of recent significant rise of PSA. He complained of muscle weakness and fatigue, since 3 weeks before the scan, without dyspnea or shortness of breath. In his 68Ga-PSMA-611 PET/CT study, widespread skeletal metastasis, as well as liver involvement were noticed. Also, multiple bilatera...

New insights in the relative radiobiological effectiveness of proton irradiation

BACKGROUND Proton radiotherapy is a form of charged particle therapy that is preferentially applied for the treatment of tumors positioned near to critical structures due to their physical characteristics, showing an inverted depth-dose profile. The sparing of normal tissue has additional advantages in the treatment of pediatric patients, in whom the risk of secondary cancers and late morbidity...
