Postherpetic neuralgia (PHN) is a debilitating complication of herpes zoster, especially in elderly and comorbid patients. Unfortunately, the currently available treatments have shown limited efficacy and some adverse events that are poorly tolerated in elderly patients. Scrambler Therapy, proposed as an alternative treatment for chronic neuropathic pain recently, is a noninvasive approach to relieve pain by changing pain perception at the brain level. Here, we report our clinical experiences on the effect of Scrambler Therapy for three patients with PHN refractory to conventional treatment.

Noninvasive monitoring of total Hemoglobin value is feasible with the use of spectroscopic measurements. As a step toward tile final goal of the development of a noninvasive monitor, the spectra$(400{\sim}800mm)$of EDTA whole blood were obtained along with reference total Hemoglobin values. Under the same condition water spectrum was generated. It was subtracted from each blood sample, and then tile first derivative of each subtracted data was taken by 'approximated first derivative algorithm' with gap (1,6,10,20nm). The correlation was obtained between total Hemoglobin and first valley wavelength of first derivative spectrum (sample number: 93).

Currently, the signal of the human body is measured with various methods, and a noninvasive investigation of various methods is useful diagnosis method. PTT(Pulse Transit Time) which is noninvasive investigation make use of to estimate the physiological phenomena. PTT has a latent information of cardiovascular system. So we have the experiments for analysis of the relations between PTT and physiological parameters. We examine to correlate to the physiological parameters, an age and degree of paralysis on the ultrasound therapy. The 40 patients who has a such paralysis join our experiment, and we obtain the PTT data that normal condition and states after ultrasound therapy. We study that PTT after the ultrasound therapy for patients who have a paralysis was related to an age and degree of paralysis.

본 논문에서는 비접촉식 이온에너지 해석 방법(Noninvasive Ion Energy Analysis, NIEA)을 이용하여 이온에너지 분포함수를 계산하고, 이 분포의 정보를 몇 가지 양으로써 특성지을 수 있는 모니터링 인자를 제안 하였다. 이온 에너지 분포에 영향을 미치는 외부 조건들인 rf 전력, 압력, 전극 간격을 변화시키며 해당 에너지 분포함수의 형태 변화 및 모니터링 인자들의 변화 양상을 관찰 하였다. NIEA 방법으로 측정한 이온 에너지와 공정과의 연관성을 알아보기 위해 poly silicon etching을 수행하며 이온 에너지 분포를 측정하였으며, 이온 에너지와 etch rate이 같은 경향을 나타내는 것을 확인 하였다.

Scars vary from mature linear scars to abnormal excessive scars such as hypertrophic scars and keloid scars. Keloid scars are fibro-proliferative disease entities that reflect an abnormal process of wound healing. They can cause pain, itching, stiffness, and psychological distress, all of which can affect quality of life. Various treatment options have been advocated as ways to prevent and treat keloid scars. These include noninvasive treatments such as use of silicone gel sheeting and compression therapy, and invasive treatments such as intralesional corticosteroid injections, surgery, and radiotherapy. Novel treatments include chemotherapy, immunotherapy, and anti-inflammatory therapies. Unfortunately, keloids continue to pose a significant challenge due to the lack of efficacious treatments. Therefore, clinicians should be familiar with various therapeutic options and apply the most suitable treatment plan for patients. In this review, we introduce the current therapeutic options for the management of keloid scars.

Noninvasive stimulation of the nervous system for treating chronic neuropathic pain has received attention because of its tolerability and relative efficacy. Repetitive transcranial magnetic stimulation (rTMS) is a representative method of noninvasive brain stimulation. Evidence-based guidelines on therapeutic use of rTMS have been proposed recently for several neurological diseases. These guidelines recommend treating neuropathic pain by applying high-frequency (≥ 5 Hz) rTMS to the primary motor cortex contralateral to the painful side. This review summarizes the mechanisms and guidelines of rTMS for treating neuropathic pain, and proposes directions for future research.
