We report two cases of patients with extensively drug-resistant Salmonella Typhi infection who had recently traveled to Pakistan. These cases suggest that obtaining a detailed travel history and considering the epidemiology of drug-resistant S. Typhi in the suspected area of acquisition is crucial for managing patients with typhoid fever.

Although 20% of patients with RDD have spontaneous remission, some cases with central nervous system (CNS) involvement require surgery or systemic treatment. We encountered a case of RDD in which hypertrophic pachymeningitis was diffuse, eliminating the need for surgical intervention.

However, anatomical pathology has remained largely an analog discipline. In recent years, this has been changing with the growing adoption of digital pathology, partly driven by the potential of computer-aided diagnosis.

- A national project in Japan, called NEWS, was established in 2014 to study the health effects of radiation on workers involved in the Fukushima disaster response in 2011.
- In 2018, researchers collected blood samples from 62 workers to assess chromosome damage and estimated radiation doses using a specialized assay.
- The results showed that biological dose estimates were significantly higher than measured doses, potentially due to factors like smoking and medical treatments, suggesting that past assessments may have overestimated actual radiation exposure for these workers.
Article Synopsis
- Following the Fukushima nuclear disaster, thyroid ultrasound examinations were conducted for residents under 18, revealing an unexpectedly high rate of pediatric thyroid cancer.* -
- A study assessed the biological effects of radiation using translocated chromosome aberrations in three groups: thyroid cancer patients, those with thyroid-related diseases, and healthy controls.* -
- Initial findings showed higher rates of chromosome aberrations in thyroid cancer patients, but differences vanished after considering previous CT scans, highlighting the impact of medical imaging on radiation exposure in young individuals.*
