OBJECTIVETo detect the presence of Porphyromonas gingivalis (Pg) and Actinobacillus actinomycetemcomitans (Aa) using polymerase chain reaction (PCR) in the oral plaque samples from children and investigate the relationship between bacteria and clinical parameters.

METHODSA total of 151 children aged 7 to 12 years were selected from Changchun Ziqiang primary school. The supragingival plaque sample was collected from the mesiobuccal and labial surfaces of the right maxillary central incisor and the right maxillary first molar. Extracted DNA from plaque samples was used for PCR analysis. Intraoral examination, probing depth (PD) and bleeding on probing (BOP) were performed and recorded.

RESULTSThe detection rate for Pg was 27.6% and Aa 54.3% in supragingival plaque. The detection rates for Pg in molars were much higher than those in incisors (P < 0.01). The detection rate of Pg was positively related to BOP+ and PD. The detection rate for Pg increased gradually with aging, and the detection rate for Aa was highest in the group aged 11 to 12 and the detection rates for Pg and Aa were higher in the gingiva with BOP+ than that with BOP- (P < 0.05). The detection rates for Pg increased remarkably with BOP+ and especially when PD was greater than 4 mm.

CONCLUSIONSDetection rates of putative periodontal pathogens from healthy children of 7 to 12 years of age were high. The detection rates for Pg in molars were much higher than those in incisors,and the presence of Pg and Aa in supragingival plaque was related to periodontal parameters.

OBJECTIVETo detect the presence of Tannerella forsythus (Tf) and Prevotella intermedia (Pi) using polymerase chain reaction (PCR) in the oral plaque samples from children and investigate the relationship between bacteria and clinical parameters.

METHODSA total of 151 children aged 7 to 12 years were selected from Changchun primary school. The supragingival plaque sample was collected from the mesiobuccal and labial surfaces of the right maxillary central incisor (FDI1) and the right maxillary first molar (FDI6). Extracted DNA from plaque samples was used for PCR analysis. Intraoral examination, probing depth (PD) and bleeding on probing (BOP) were performed and recorded.

RESULTSThe detection rate for Tf was 40.3% (118/293) and Pi was 46.4% (136/293) in supragingival plaque. The detection rates for Tf and Pi in molars were much higher than those in incisors (P < 0.01). The detection rate of Tf and Pi was positively related to BOP+ and PD. The detection rate for Pi decreased gradually with age, and the detection rate for Tf was highest in the group aged 7 to 8 and the detection rates for Tf and Pi were higher in the gingiva with BOP+ than that with BOP- (P > 0.05). The detection rates for Tf increased remarkably with BOP+ and especially when PD was greater than 4 mm.

CONCLUSIONSDetection rates of putative periodontal pathogens from healthy children of 7 to 12 years of age were high. The detection rates for Tf and Pi in molars were much higher than those in incisors, and the presence of Tf and Pi in supragingival plaque was related to periodontal parameters.

[Objective] We report a successfully treated case by a combined therapy of acupuncture and Kampo medicine for a patient with lower limb pain associated with Guillain-Barre syndrome (GBS).[Case] The patient was a 74-year-old man whose chief complaints were severe lower limb pain, gait difficulty, and hyposthenia. Clinical history: In late September in X year, the patient had a cold infection. On October 14, he became aware of weakness in his lower limbs on both sides, difficulty in walking, and severe pain in his lower limbs. He visited our hospital's general internal medicine department and was diagnosed with GBS. The patient was hospitalized and started to receive intravenous immunoglobulin therapy for GBS. Since pain in the lower limbs continued after treatment, he received analgesics, which was not effective. Therefore, acupuncture treatment was started on October 30 aiming to alleviate lower limb pain. Evaluation: Pain and burning sensation were evaluated using a numerical rating scale (NRS), and Hughes' function grade scale (FG) as an objective evaluation. [Acupuncture treatment] The acupuncture treatment was based on Chinese medicine. The basic combination of meridian points for treatment of the case were LR3 (Taichong), LI4 (Hegu), KI6 (Zhaohai), KI3 (Taixi), ST36 (Zusanli), PC6 (Neiguan), and SI8 (Xiaohai). The patient received acupuncture treatments once a day for 12 weeks.[Progress] The first evaluation of the patient's pain in his lower limbs on both sides was 10 points in NRS and 4 units in FG. Pain was alleviated immediately after acupuncture treatment was started, and a significant improvement in pain was observed by the seventh acupuncture treatment. However, the　patient started to complain of burning sensation on his soles. Therefore, the combined use of Kampo medicine (Choutousan, Rokumijiougan) were introduced in addition to the acupuncture treatment, and his burning sensation disappeared. Since then, rehabilitation was enhanced, and after three months from the start of acupuncture treatment, he was discharged since the FG was improved to 2 units. [Discussion] Lower limb pain and burning sensation in this case were considered to be neuropathic pain associated with GBS, and conventional analgesics were only temporarily effective. In contrast, the combined use of acupuncture and Kampo medicine alleviated the pain and burning sensation, and ADL was improved. Acupuncture and Kampo medicine were effective for lower limb pain and burning sensation from GBS.
