Several wars and pandemics have demonstrated the serious impacts of infectious diseases on the military, highlighting the importance of infection control. As a national defense organiza-tion, the military operates within specific cultural and environmental contexts distinct from civilian organizations. The unique conditions of war necessitate extensive efforts to prevent in-fections. Therefore, a strategic approach based on the understanding of its unique strengths and challenges is essential for proper infection control in the military. As the military is nationally dispersed and in contact with the surrounding communities, the readiness of this organization,along with its personnel, resources, and operational systems, is crucial for the protection ofsoldiers and civilians during infectious disease outbreaks. Therefore, joint efforts and academic and practical exchanges between the military and civilian sectors based on the comprehensiveunderstanding of the military conditions and operations are necessary for prompt response to and control of infectious diseases.

Allan-Herndon-Dudley syndrome (AHDS) is a rare X-linked neurodevelopmental disorder with abnormal thyroid function caused by mutation in the solute carrier family 16 member 2 (SLC16A2) gene. Clinical manifestations of AHDS are global or axial hypotonia, a variety of movement disorders, severe intellectual disability, quadriplegia or spastic diplegia, growth failure, and seizures. A 10-year-old boy visited our hospital with the chief complaint of newly onset generalized tonic seizures with vocalization of weekly to daily frequency. He showed early infantile hypotonia, severe intellectual disability, and frequent respiratory infections. He could not walk independently and was non-verbal. Electroencephalogram revealed generalized slow spike and waves with multifocal spikes and slow background rhythms. His tonic seizures were controlled with more than two anti-seizure medications (ASMs). At 11 years of age, he was evaluated for thyroid function as part of regular screening for ASM maintenance and was found to have abnormal thyroid function. We performed whole exome sequencing for severe global developmental delay, drug-resistant epilepsy, and abnormal thyroid function. The hemizygous c.940C>T (p.Arg314Ter) variant in the SLC16A2 gene (NM_006517.5) was identified and confirmed based on Sanger sequencing. Herein, we describe a case of an AHDS patient with late-onset drug-resistant epilepsy combined with congenital hypotonia, global developmental delay, and abnormal thyroid function results. To the best of our knowledge, this is the oldest adolescent among AHDS cases reported in Korea. In this report, clinical characteristics of a mid-adolescence patient with AHDS were presented.
