These studies showed that in adolescent rodents exposed to caffeine, functioning of serotonin systems was affected, leading to increased anxiety; anxiety-related behaviors were higher than in adult rats exposed to the same amount of caffeine; and reward seeking behaviors as well as mood fluctuations were increased as the rodents matured. Long-term health effects
When consumed in moderation, caffeine can have many beneficial effects. However, over the course of several years, chronic caffeine consumption can produce various long-term health deficits in individuals. Among these, rodent studies have suggested caffeine intake may permanently alter the brains excitability. As previously stated, long-term effects are most often seen in adolescents who regularly consume excess amounts of caffeine. This can affect their neuroendocrine functions and increase the risk of anxiety-disorder development. Treatment
For individuals being treated with benzodiazepines such as alprazolam (Xanax) for anxiety disorders, even small amounts of caffeine may have negative effects on treatment. Caffeine is able to negate the effects of benzodiazepines which can lead to heightened levels of anxiety and even panic attacks. Studies have linked caffeine intake to increased rates of cytotoxicity and cell death by necrosis associated with benzodiazepine use. However, this phenomenon (thought to be mediated via TSPO) is also present with benzodiazepine use alone. The clinical significance of caffeine-benzodiazepine induced cytotoxicity in humans is unclear and has not been shown to be harmful. Although benzodiazepines are effective at managing acute caffeine-induced anxiety symptoms,  avoiding caffeine is generally recommended rather than increasing benzodiazepine intake.
White piedra (or tinea blanca) is a mycosis of the hair caused by several species of fungi in the genus Trichosporon. It is characterized by soft nodules composed of yeast cells and arthroconidia that encompass hair shafts. Diagnosis
White piedra can occur on the hair of the scalp; Trichosporon ovoides is likely the cause in this case. White piedra on scalp hair is rarely caused by Trichosporon inkin; pubic hair with white piedra is what T. inkin is mainly associated with. White piedra can occur on pubic hair; T. inkin likely causes this.Trichosporon beigelii

Treatment
There are several approaches to treat this infectious disease. One approach involves shaving the affected areas. Another approach involves the use of antifungal medication. See also
