abnormal transient elastography. No correlation for gender, cumulative dose, age, duration of treatment or presence of psoriatic arthritis was found.Our population is very overweight which is reflected in our number of failed tests (36.2% of 105). These results are similar to previous findings in NZ (25% in 133 patients) and Ireland (35% in 77 patients). 5,6 Like many other studies, obesity was associated with abnormal TE results. It is unsurprising that 14 of our 15 patients with severe liver fibrosis had NAFLD/NASH. Our drug survival (mean 72.5 months) is favourable compared with other studies, suggesting that patients are being successfully treated for long periods. 7,8 Transient elastography monitoring in our population is important as it identifies significant NAFLD/NASH.
Endovascular interventional procedures are widely used for the treatment of intracranial vascular lesions. However, they sometimes produce reversible alopecia, known as radiation-induced temporary alopecia, depending on the radiation dose. Radiation-induced temporary alopecia manifested as rectangular alopecic patches without signs of inflammation, reflects damage to the keratinocytes in the hair matrix of anagen hair follicles, due to the sensitivity of these cells to radiation. The characteristics of radiation-induced temporary alopecia are similar to those of alopecia areata as follows: (1) clinical findings of well-defined alopecic patches and (2) dermoscopic findings of yellow dots, black dots, and short vellus hairs. The two conditions can be distinguished according to whether there is any history of endovascular interventional procedures, and by the shapes of the lesions and the inflammation status on histopathologic examination. A hair microscopic examination is a useful diagnostic tool in patients with hair loss disease, but the features of radiation-induced temporary alopecia have not been well described. Here, we report three cases of radiation-induced temporary alopecia preceded by endovascular procedures, including stent insertion and coil embolization.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
