The high risk of developing postherpetic neuralgia (PHN) is associated with severe immunosuppressive diseases. A malignancy itself, as well as surgery, radiotherapy, and other treatments, can lead to changes in the immune status of the body and predispose patients with a malignancy to PHN. ⋯ The NRS-11 score in the acute phase, whether the use of antiviral drugs in sufficient quantities, and tumor staging are the influencing factors of PHN after malignant tumors.

Subdural hematoma (SDH) is a potentially life-threatening complication in patients with spontaneous intracranial hypotension (SIH). Though bed rest is the basis of conservative treatment, no clear evidence exists regarding the association between bed rest and the later complication of SDH in these patients. ⋯ Bed rest was a protective factor for SDH in patients with SIH. With more time and proper treatment, patients with SIH who have an SDH can achieve good prognosis in the long term.

There is a global shortage of iohexol contrast media, commonly used in epidural injections, as a result of lockdown and decreased production due to COVID-19. Iohexol bottles are designated for single use, which, depending on the vials available, often leads to wasting up to 95% of this limited resource. However, avoiding multiple withdrawals may be unnecessary if withdrawing multiple times using sterile technique does not increase the risk for contamination. ⋯ Our results suggest that single-use 300 iohexol bottles may be reusable and that the contrast media is mildly antimicrobial, but not enough to retard contamination. In setting of shortages, contrast media bottles can safely be reused. This is valuable for conserving resources and limiting unnecessary health care-associated costs.
