ABSTRACT
Post-traumatic stress disorder (PTSD) is a debilitating psychiatric condition for which pharmacological therapy is not always solvable. Various treatments have been suggested and deep brain stimulation (DBS) is currently under investigation for patients affected by PTSD. We review the neurocircuitry and up-to-date clinical concepts which are behind the use of DBS in posttraumatic stress disorder (PTSD). The role of DBS in treatment-refractory PTSD patients has been investigated relying on both preclinical and clinical studies. DBS for PTSD is in its preliminary phases and likely to provide hope for patients with medical refractory PTSD following the results of randomized controlled studies.
ABSTRACT
GOAL: Psoriasis is a chronic skin disease which is very common in the population and requires frequent clinical and pharmacological treatment. In the following, a study based on Fourier transform infrared spectroscopy analyzing saliva proteomic components in psoriatic patients against diabetic patients and a control group is presented. Clinical analysis showed a prominent amide II band, at around 1545 cm(-1), and the composition of the amide I band, at around 1647 cm(-1), allowing us to distinguish the infrared salivary signature of psoriatic and diabetic patients from the control group and even from patients with different kinds of psoriasis. Moreover, results highlighted existing differences in the secondary structure composition of proteins between psoriatic and diabetic patients as compared to the control group. In fact, the saliva spectra of the control group and that of the palmoplantar psoriatic patients differ from plaque psoriasis and diabetic patient spectra because of the absence of the amide II band and the presence of different secondary protein-structure conformations.
