An 8-year-old girl was admitted with vision loss. She had no history of amblyopia or other eye diseases. On examination, both eyes showed vision loss and uncorrected myopia, regardless of visual acuity correction by glasses. Her symptoms were considered exacerbated by fatigue. We diagnosed tonic accommodation because a regulatory paralysis agent provided relief. The patient had been treated with tropicamide methyl sulfate and neostigmine, but her visual acuity did not change. Based on a Kampo diagnosis, she was prescribed Shokenchuto. After 4 months' administration, her uncorrected vision improved by 1.2 in both eyes, and her visual acuity was maintained even when fatigued. Kampo medicine can be a treatment option for tonic accommodation in cases where standard treatments are ineffective.

A 54-year-old female had cesarean sections at ages 26 and 29, a left salpingophrectomy for left ovarian cyst at age 31, and a total abdominal hysterectomy for fibroids at age 41. After total abdominal hysterectomy, she had repeated bouts of ileus and started taking daikenchuto (DKT), which is commonly used to prevent ileus. At age 54, she visited our hospital when DKT failed to relieve her constipation and lower abdominal pain and had occasional heat flash above her neck. Tongue examination revealed pale red tongue and fissured tongue signs with yellow fur and dilation of the sublingual collateral vessels. Kampo diagnosis was blood stasis and excess heat, for which keishibukuryogan was prescribed to be taken daily and with which her symptoms dissipated after 7 days. Despite the popular use of DKT, its potential to cause excess heat after long-term use is not as well known. It is extremely important to warn clinicians who prescribe Kampo not to focus solely on a disease-to-prescription model but also to be learned of the discipline and to take measures to prevent adverse long-term effects and complications.

PURPOSE: This study investigated the effects of bone density and crestal cortical bone thickness at the implant-placement site on micromotion (relative displacement between the implant and bone) and the peri-implant bone strain distribution under immediate-loading conditions. METHODS: A three-dimensional finite element model of the posterior mandible with an implant was constructed. Various bone parameters were simulated, including low or high cancellous bone density, low or high crestal cortical bone density, and crestal cortical bone thicknesses ranging from 0.5 to 2.5 mm. Delayed- and immediate-loading conditions were simulated. A buccolingual oblique load of 200 N was applied to the top of the abutment. RESULTS: The maximum extent of micromotion was approximately 100 μm in the low-density cancellous bone models, whereas it was under 30 μm in the high-density cancellous bone models. Crestal cortical bone thickness significantly affected the maximum micromotion in the low-density cancellous bone models. The minimum principal strain in the peri-implant cortical bone was affected by the density of the crestal cortical bone and cancellous bone to the same degree for both delayed and immediate loading. In the low-density cancellous bone models under immediate loading, the minimum principal strain in the peri-implant cortical bone decreased with an increase in crestal cortical bone thickness. CONCLUSIONS: Cancellous bone density may be a critical factor for avoiding excessive micromotion in immediately loaded implants. Crestal cortical bone thickness significantly affected the maximum extent of micromotion and peri-implant bone strain in simulations of low-density cancellous bone under immediate loading.

PURPOSE: The purpose of this study was to investigate the effects of implant tilting and the loading direction on the displacement and micromotion (relative displacement between the implant and bone) of immediately loaded implants by in vitro experiments and finite element analysis (FEA). METHODS: Six artificial bone blocks were prepared. Six screw-type implants with a length of 10 mm and diameter of 4.3 mm were placed, with 3 positioned axially and 3 tilted. The tilted implants were 30° distally inclined to the axial implants. Vertical and mesiodistal oblique (45° angle) loads of 200 N were applied to the top of the abutment, and the abutment displacement was recorded. Nonlinear finite element models simulating the in vitro experiment were constructed, and the abutment displacement and micromotion were calculated. The data on the abutment displacement from in vitro experiments and FEA were compared, and the validity of the finite element model was evaluated. RESULTS: The abutment displacement was greater under oblique loading than under axial loading and greater for the tilted implants than for the axial implants. The in vitro and FEA results showed satisfactory consistency. The maximum micromotion was 2.8- to 4.1-fold higher under oblique loading than under vertical loading. The maximum micromotion values in the axial and tilted implants were very close under vertical loading. However, in the tilted implant model, the maximum micromotion was 38.7% less than in the axial implant model under oblique loading. The relationship between abutment displacement and micromotion varied according to the loading direction (vertical or oblique) as well as the implant insertion angle (axial or tilted). CONCLUSIONS: Tilted implants may have a lower maximum extent of micromotion than axial implants under mesiodistal oblique loading. The maximum micromotion values were strongly influenced by the loading direction. The maximum micromotion values did not reflect the abutment displacement values.

Until the Sui Dynasty in China, night sweat and spontaneous perspiration had been thought to be caused by same pathophysiology, that is, lowered superficial resistance by deficiency of Qi.In the Tang Dynasty, these were considered to have different pathophysiologies and a new principle indicated that pathogenic heat caused night sweat.In the Song and Jing Dynasties, deficiency of blood and pathogenic heat by deficiency of Yin was also considered to cause night sweat.In the Jing Dynasty, exogenous pathogens, such as Cold were considered to cause night sweat, which indicated the principle that not only the deficiency syndrome but also the excess syndrome caused night sweat.In the beginning of the Yuan and Ming Dynasties, it was concluded that the deficiency of Yin caused night sweat and the deficiency of Yang caused spontaneous perspiration.In the middle of the Ming Dynasty, another new theory indicated that deficiency of Yang also possibly caused night sweat; therefore we should diagnose abnormal sweat depending on the pathophysiology in each case.In the Qing Dynasty, new theories were established stating that not only exogenous pathogens but also Damp-heat, undigested food and stagnation of blood, all of which are included in excess syndrome, cause night sweat, and that based on which part of the body sweats occurred we might understand pathophysiology of night sweat. The night sweat by Warm-heat, which is different from the one by Wind-cold, was considered to be caused with deficiency of Yin.Thus we conclude that the theories of night sweat developed over time, based on Chinese medical classics.

Dang Gui Liu Huang Tang (in the Lan Shi Mi Cang written by Li Dong-yuan) is a common medicine for treating night sweats. We describe its historical development and therapeutic uses. The use of Huan qi (Radix Astragali sen Hedysari) is based on the Han-Sui dynasty medical principle that night sweats are mainly caused by Deficiency of Yang. Herbs to enrich the lood and Yin, Dang gui (Radix Angelicae Sinesis), Seng di huang (Radix Remannia), Shu di huang Radix Rehmannia preparata) were later added because Son dynasty physicians mentioned that Yin deficiency caused night sweats. The addition of heat-reducing herbs, such as Huang lian (Rhizoma Coptidis), was based on the Song dynasty theory that night sweats are caused by pathologic heat in the body, which forces body fluid out of the skin. In the same period, the herbal medicine called Da Jin Hua Wan created by Liu Wansu, and this greatly influenced the principles for treating night sweats. The clearest explanation can be found in the medical treaties Huang Di Nei Jing Su Wen, and Xuan Ming Lun. This medical combination was based on medical theories from a number of historical periods, which may explain its effectiveness. Dang Gui Liu Huang Tang is not effective against types of weak heat (Dan xin xin fa), severe vital Qi Deficiency (Zhang shi yang), or serious deficiency of Yin (Yi xue xin wu). It sometimes hurts Pi and Wei (digestive system). It is useful in the treatment of spontaneous perspiration (Yi xue zheng zhuang, Jin xue quan shu). In summary, this medicine is most effective when the seriousness of heat and Yin deficiency are almost equal and a slight Qi Deficiency exists, or in cases of spontaneous perspiration.

Tenmin NAMIKAWA (並河天民) thought the Shanghanlun (傷寒論) was an important text. He also taught his pupils the importance of prescribing Zhongjing ZHANG's (張仲景) medicines. Ryokyu ARIMA (有馬凉及) was a physician-teacher, who prescribed Chengqitang (承気湯) for the emperor without conferring with other doctors. His chengqitang formulary was derived from medical texts by Zhongjing ZHANG. Kyugo GODA (合田求吾) on the other hand, was a pupil of Ikkannsai MATSUBARA (松原一閑斎), who wrote in the Idokikigaki (医道聞書) : theKoho (古方) school started by Ryokyu ARIMA. He was a hero who was punished by the Goseiin (後西院) emperor. He taught Koho to Tenmin. This therefore reveals that Ryokyu ARIMA was a teacher who taught the importance of the Shanghanlun.

ART (Assisted Reproductive Technology) is making impressive advancements. However, not all patients will successfully conceive even with this technique. Patients undergoing infertility treatment are predominantly in a state of mental stress for being unable to conceive, and the importance of stress care in treating infertility has been reported. This time, to investigate the relationship between infertility, mental stress and Kampo treatment, we have conducted a retrospective study on 7 patients who achieved conception by a combination treatment of Kampo medicine and ovulation day prediction. Patients'occupation, menstruation history, pregnancy history, premenstrual symptoms, and oriental medical examination findings were extracted from their medical records. The clinical background were age (mean age: 36 [29-39]), time to pregnancy (mean: 6 months [2-9 months]), and outcome (normal vaginal delivery [3 cases], caesarean section [2 cases], abortion [1 case], transfer to other facility [1 case]). The oriental medical diagnosis in all cases found stagnation of liver qi. Two cases had only stagnation of liver qi. As comorbidities, kidney deficiency (3 cases), blood stasis syndrome (1 case), and blood stasis syndrome with syndrome of dual deficiency of qi and blood (1 case) were found. The Kampo prescriptions were as follows: nyoshinsan (2), kamishoyosan (2), tsudosan (1), shigyakusan (1) and kyukichoketsuin (1). Stagnation of liver (TM) qi was considered to play a role in infertility and is one of the important factors in Kampo prescriptions.

We evaluated body constituents patterns of 74 consecutive patients with neurological degenerative disorders. They comprise Parkinson's disease (n = 38), amyotrophic lateral sclerosis (n = 19), and multiple system atro­phy (n = 17). We compared body constituents patterns between them and 149 consecutive patients with other neurological diseases of the same age. We used ki-ketsu-sui scores to evaluate body constituents patterns in all cases. Ki-ketsu-sui scores measure six factors : qi deficiency (kikyo), qi stagnation (kiutsu), qi counterflow (kigyaku), blood deficiency (kekkyo), blood stasis (oketsu), and fluid retention (suitai). As a result of multi­variate analysis, neurological degenerative disorders had large weight of blood deficiency, fluid retention and qi stagnation. Their adjusted odds ratios (95% confidence interval) were 3.02 (1.43-­6.48), 2.37 (1.13-­5.11), 2.33 (1.01-­5.44), respectively. Most relevant factor to neurological degenerative disorders was a blood defi­ciency. Taking into consideration a prescription of “shimotsuto rui” may contribute to alleviate patient's suf­fering. In addition to subjective symptoms, we need an oriental medicine scale such as pulse, tongue, and ab­dominal examinations to judge a therapeutic effect of Kampo medicine.

In dentistry, it is empirically known that the acute exacerbation of periodontal disease often occurs at the time of fatigue, but scientific verification has never been made about the relationship of fatigue and bleeding. In Kampo medicine, there is the concept of spleen failing to control the blood as bleeding at the time of fatigue. Kihito and kamikihito are often used for this condition. Spleen failing to control the blood means that lack of vital energy causes the bleeding. Kamikihito is most often used in the treatment of idiopathic thrombocytopenic purpura. Moreover, there have been some reports on the use of kamikihito in the treatment of gynecological fraud bleeding and aplastic anemia. However, there has been no report on the use of it in the treatment of gingival bleeding. In this case, neither cytopenia nor obvious coagulopathy was recognized. In Kampo medicine, not only spleen failing to control the blood but also blood stasis or blood heat is considered to be the cause of bleeding, but the effectiveness of kamikihito for this case suggested pathophysiology of spleen failing to control the blood. Kamikihito could be a choice to treat gingival bleeding at the time of fatigue.
