Herein, we report the effectiveness of Korean medicine for the treatment of postherpetic upper limb weakness and pain. The patient received a combination of Korean medicine treatment modalities, including electroacupuncture, pharmacopuncture, and herbal medicine. Muscle strength and pain were evaluated using a manual muscle test (MMT) and a Numerical Rating Scale (NRS), respectively. The overall MMT score improved after hospitalization, and elbow extension improved from 3+ at admission to 5 at discharge. The NRS score improved to 2 at discharge. This study suggests the effectiveness of a combination of Korean medicine modalities in treating postherpetic motor nerve paralysis.

Objective: To evaluate differences in the adhesion levels of the most common oral pathogens, Streptococcus mutans and Porphyromonas gingivalis, in human saliva-derived microcosm biofilms with respect to time and raw materials of orthodontic brackets. Methods: The samples were classified into three groups of bracket materials: 1) monocrystalline alumina ceramic (CR), 2) stainless steel metal (SS), and 3) polycarbonate plastic (PL), and a hydroxyapatite (HA) group was used to mimic the enamel surface. Saliva was collected from a healthy donor, and saliva-derived biofilms were grown on each sample. A real-time polymerase chain reaction was performed to quantitatively evaluate differences in the attachment levels of total bacteria, S. mutans and P. gingivalis at days 1 and 4. Results: Adhesion of S. mutans and P. gingivalis to CR and HA was higher than the other bracket materials (SS = PL < CR = HA). Total bacteria demonstrated higher adhesion to HA than to bracket materials, but no significant differences in adhesion were observed among the bracket materials (CR = SS = PL < HA). From days 1 to 4, the adhesion of P. gingivalis decreased, while that of S. mutans and total bacteria increased, regardless of material type. Conclusions: The higher adhesion of oral pathogens, such as S. mutans and P. gingivalis to CR suggests that the use of CR brackets possibly facilitates gingival inflammation and enamel decalcification during orthodontic treatment.
