While the rarity of HaNDL syndrome often precludes reassurance of the nature of this syndrome, it has consistently been identified as a benign condition that lasts no longer than 3 mo.</p><p><strong>Case report: </strong>In the first week of a viral illness, a 29-yr-old male helicopter pilot experienced acute-onset \"stumbling\" when walking, \"nonsensical speech,\" migraine-like headache, scintillating scotomata, and paresthesias of the tongue and bilateral extremities that lasted for 4-6 h. Work-up included lumbar puncture, revealing lymphocytic pleocytosis. A week later, he experienced word-finding difficulty, right-sided numbness/paresthesia, and severe occipital headache lasting 3 h. A third episode with sensory symptoms involving the tongue and right arm and leg occurred for a few hours 25 d after the onset of the first episode. Symptoms resolved spontaneously. A month following initial discharge, he denied symptom recurrence. Repeat lumbar puncture 4 mo later showed resolution of his pleocytosis. He was considered neurologically recovered 3 mo after symptom onset.</p><p><strong>Discussion: </strong>This patient's transient episodes were consistent with HaNDL syndrome. His symptom resolution involving three episodes within 25 d reflects the transient nature of this condition. It is critical to recognize HaNDL syndrome as a benign, monophasic disorder that resolves within a maximum of 3 mo so that future pilots with a recent history of HaNDL syndrome may safely and expeditiously return to work.

Microgravity, limited hygiene, and radiation uniquely impair skin integrity, contributing to issues such as dermal atrophy, xerosis, and increased infection risk during spaceflight. This commentary highlights practical strategies and potential research avenues for preventing and addressing the array of dermatologic changes during spaceflight. There are multiple promising interventions, including retinoids, vitamin-A derivatives, calcitriol, L-asparaginase, advanced dressings, telemedicine, and immune-system enhancement strategies which may help mitigate skin-thinning, dermatitis, and slow wound-healing. Continued interdisciplinary collaboration, more human data, and real-time data collection will refine and validate strategies, improving skin health in space.

Pachychoroid neovasculopathy is a relatively recently recognized clinical entity of choroidal neovascularization, belonging to the pachychoroid spectrum, for which intravitreal therapy (IVT) is the standard of care. The main aeromedical considerations are degradation of visual function from disease progression, which could preclude aircrew from flying duties, and the compatibility of IVT with flying.</p><p><strong>Case report: </strong>A trained Republic of Singapore Air Force aircrew operator on board the Fokker-50 first presented with a reduction in visual acuity at his annual aircrew medical examination, for which he was restricted from flying duties for further evaluation.

He was started on monthly IVT for 3 mo before being placed on a treat-and-extend regimen. After 10 mo of treatment totalling five doses of aflibercept IVT, he achieved resolution of subretinal fluid and recovery of visual acuity, stereopsis, and color vision.
