Erythropoietic protoporphyria (EPP) is a genetic disorder stemming from reduced ferrochelatase expression, the final enzyme in the pathway of heme biosynthesis. A closely related condition, X-linked protoporphyria (XLP), bears similar clinical features although it arises from the heightened activity of δ-aminolevulinic acid synthase 2 (ALAS2), the first and normally rate-controlling enzyme in heme biosynthesis in developing red blood cells. Both of these abnormalities result in the buildup of protoporphyrin IX, leading to excruciating light sensitivity and, in a minority of cases, potentially fatal liver complications. Traditionally, managing EPP and XLP involved sun avoidance. However, the emergence of innovative therapies, such as dersimelagon, is reshaping the therapeutic landscape for these conditions. In this review, we summarize salient features of the properties of dersimelagon, shedding light on its potential role in advancing our understanding of treatment options for EPP and XLP.

Children who are inadequately treated for depression often experience greater dysfunction. Problems can include conduct disorders, substance abuse, physical illness, and poor performance at school, work, or in psychosocial contexts. Depression can lead to a greater risk of suicide. Suicide is the third most common cause of death among adolescents, with more than 500,000 attempts made by children each year. Suicide is the third most frequent cause of death among young people ages 10 to 19 years old. Thus, proper treatment is important. Major depressive disorder in adolescents is often followed by frequent recurrences in adulthood. Imaging studies document underactivity in the left dorsolateral prefrontal cortex in subjects suffering from depression. Activation of the brain with high-frequency transcranial magnetic stimulation increases neuronal excitability and induces the growth of new connections. Though larger, randomized, controlled trials with more patients and longer follow-up are needed, the favorable side effect profile and efficacy of TMS seen so far in the literature support the use of TMS as a therapeutic intervention in children and adolescents with depression.
