本研究では,地盤に含まれる硫酸イオンおよび硫酸塩によるコンクリートの硫酸塩劣化について取り上げた.はじめに,旧産炭地域のぼたを用いた盛土地盤と新第三紀泥岩層の造成地盤における住宅基礎コンクリートの劣化既往事例を概説し,その原因が地盤に含まれる硫酸イオンおよび硫酸塩によるものであることを示した.次に,黄鉄鉱を含む海成層による堆積地盤において,細菌の作用により黄鉄鉱が酸化され,硫酸イオンが生じる過程を示した上で,日本各地の地盤中に含まれる硫酸イオン濃度について考察した.最後に,地質と気象要因に基づき,日本全土におけるコンクリートの硫酸塩劣化の可能性を有する地盤を「コンクリートの腐食程度の厳しさ」として提案した.

【緒言】染色体異常のある先天性障害児の生活の質が,漢方治療にて改善した2例について検討した。【症例1】5p 欠失症候群の6歳男児。興奮性と不眠の加療目的で甘麦大棗湯に小建中湯を追加,さらに抑肝散を併用後,明らかに興奮する度合いが減り朝まで熟睡するようになった。【症例2】2歳男児。8番染色体異常あり。胸部術後に抜管困難となり,気管切開,胃瘻造設となった。5から15分に1回と,頻回な吸痰が必要で,また常に下痢するとして漢方治療開始。茯苓飲合半夏厚朴湯にて吸痰回数減少し,小建中湯を追加後,2時間以上吸引が不要となり,下痢も改善した。気切部位閉鎖術後も黄耆建中湯,小青竜湯,人参湯にて経過をみているが,保育園に通園するようになり非常に元気に過ごしている。【考察】生命予後には関与しないような小さな改善ではあるが,生活の質向上と養育者の負担軽減に寄与できた。小児へ漢方治療を行うことのひとつの意義と考える。

この研究は、日本の看護師を対象として、「看護師の共感能力を評価する臨床対人反応性指標(原版)が共感を評価することができているか」を検証することを目的とした。この研究の対象者は、国立大学病院に所属する看護師と看護学研究者であった。分析を行った結果、臨床対人反応性指標は、18項目であり、2つの共感の要素を評価できることが明らかになった。その2つの要素は、患者の視点に立って患者を理解する「視点取得」と如何なる患者も無条件に理解しようとする「無条件の肯定的理解」を評価することが確認された。この共感の指標を用いて、共感を教育していくことで、看護師の共感の能力は向上すると考えられる。

Introduction: Few studies have investigated the influence of cage subsidence patterns (intraoperative endplate injury or late-onset cage settling) on bony fusion and clinical outcomes in lateral interbody fusion (LIF). This retrospective study was performed to compare the fusion rate and clinical outcomes of cage subsidence patterns in LIF at one year after surgery.Methods: Participants included 93 patients (aged 69.0±0.8 years; 184 segments) who underwent LIF with bilateral pedicle screw fixation. All segments were evaluated by computed tomography and classified into three groups: Segment E (intraoperative endplate injury, identified immediately postoperatively); Segment S (late-onset settling, identified at 3 months or later); or Segment N (no subsidence). We compared patient characteristics, surgical parameters and fusion status at 1 year for the three subsidence groups. Patients were classified into four groups: Group E (at least one Segment E), Group S (at least one Segment S), Group ES (both Segments E and S), or Group N (Segment N alone). Visual analog scales (VASs) and the Japanese Orthopedic Association Back Pain Evaluation Questionnaire (JOABPEQ) were compared for the four patient groups.Results: 184 segments were classified: 31 as Segment E (16.8%), 21 as Segment S (11.4%), and 132 as Segment N (71.7%). Segment E demonstrated significantly lower bone mineral density (-1.7 SD of T-score, p=0.003). Segment S demonstrated a significantly higher rate of polyetheretherketone (PEEK) cages (100%, p=0.03) and a significantly lower fusion rate (23.8%, p=0.01). There were no significant differences in VAS or in any of the JOABPEQ domains among the four patient groups.Conclusions: Intraoperative endplate injury was significantly related to bone quality, and late-onset settling was related to PEEK cages. Late-onset settling demonstrated a worse fusion rate. However, there were no significant differences in clinical outcomes among the subsidence patterns.

Introduction: Molecular pathways involved in ligamentum flavum (LF) hypertrophy are still unclarified. The purpose of this study was to characterize LF hypertrophy by microRNA (miRNA) profiling according to the classification of lumbar spinal stenosis (LSS).Methods: Classification of patients with LSS into ligamentous and non-ligamentous cases was conducted by clinical observation and the morphometric parameter adopting the LF/spinal canal area ratio (LSAR) from measurements of magnetic resonance imaging (MRI) T2 weighed images. LF from patients with ligamentous stenosis (n=10) were considered as the degenerative hypertrophied samples, and those from patients with non-ligamentous LSS (n=7) and lumbar disc herniation (LDH, n=3) were used as non-hypertrophied controls. Profiling of miRNA from all samples was conducted by Agilent microarray. Microarray data analysis was performed with GeneSpring GX, and pathway analysis was performed using Ingenuity Pathway Analysis.Results: The mean LSAR in the ligamentous group was significantly higher than that in the control group (0.662±0.154 vs 0.301±0.068, p=0.0000171). Ten significantly differentially expressed miRNA were identified and taken as a signature of LF hypertrophy: nine miRNA showed down-regulated expression, and one showed up-regulated expression in the ligamentous LF. Among those, miR-423-5p (rs=-0.473, p<0.05), miR-4306 (rs=-0.628, p<0.01), miR-516b-5p (rs=-0.629, p<0.01), and miR-497-5p (rs=0.461, p<0.05) were correlated to the LSAR. Pathway analysis predicted aryl hydrocarbon receptor signaling (p<0.01), Wnt/β-catenin signaling (p<0.01), and insulin receptor signaling (p<0.05) as canonical pathways associated with the miRNA signature.Conclusions: Classification based on quantification of the MRI axial image is useful for studying hypertrophy of the LF. Aryl hydrocarbon receptor and Wnt/β-catenin signaling may be involved in LF hypertrophy.

Background: To avoid lateral misplacement of midcervical pedicle screws, we developed a method for Minimally Invasive Cervical Pedicle Screw (MICEPS) fixation via a posterolateral approach. This intramuscular approach allows for horizontal pedicle screw insertion and reduced intraoperative bleeding. We reviewed our initial experience with MICEPS fixation for patients with cervical metastases.Methods: This study included 18 consecutive patients who received cervical spinal surgery for metastatic tumor. We treated 12 patients with conventional cervical pedicle screw fixation, and 6 patients with the MICEPS fixation technique. Average follow-up was 14 months (range 3 to 34). We inserted 117 pedicle screws using the navigation system. Average fusion area was 4.9 vertebrae (range 3 to 8). Alpha-angles between a line perpendicular to the posterior cortex of the vertebral body and the screw trajectory in the transverse plane were also measured.Results: The average surgical time was 250 min (range 151 to 420 min) with the conventional pedicle screw fixation and 234 min (range 154 to 300 min) with the MICEPS fixation. The average total blood loss was 780 mL (range, 180-1430 mL) in the conventional pedicle screw fixation group and 180 mL (range, 70-400 mL) in the MICEPS fixation group. At the level of midcervical (C3-5), average alpha-angles was 52 degrees (range 43 to 62) in MICEPS fixation group, and 39 degrees (range 19 to 55) in conventional cervical pedicle screw group.Conclusions: The MICEPS fixation technique uses an intramuscular approach, which is minimally invasive and reduces intraoperative bleeding. Intramuscular approach allows for horizontal pedicle screw insertion, and reduced critical screw deviation.

It is not easy to treat patients with intractable Meniere's disease. Intratympanic injection of gentamicin or steroid is one option. The other is a surgical procedure like endolymphatic shunt surgery. Middle ear pressure treatment using the Meniett device, which has not been approved by the Japanese government is widely accepted in foreign countries. We had a chance to use this Meniett device under approval of the ethic's committee of Hino Municipal Hospital since September 2004. ‹Methods› Four patients with intractable Meniere's disease who suffered intensive vertigo attack for more than 5 months with conservative medical treatment were employed in the study. Ages ranged from 67 to 72, with 3 females and 1 male. After a ventilation tube was inserted under local anesthesia, treatment with the Meniett was performed 3 times a day at home. ‹Results› Two patients improved and 2 slightly improved concerning vertigo attacks. One showed no change, 1 experienced a worsening, and 2 showed slight improvement concerning the hearing level. ‹Conclusion› The Meniett device is less invasive and may be suitable for elderly patients who prefer conservative treatment. The mechanism involved in the reduction of vertigo attacks is not clear so far, but we speculate that middle ear pressure may suppress serum vasopressin (antidiuretic hormone) secretion and thereby reduce endolymphatic hydrops. It is necessary to accumulate treatment data with the Meniett in Japan to obtain official approval by the government.

The effect of an alerting odorant on the secretion of salivary cortisol during sleep and after awakening was investigated. Salivary cortisol was assessed because this glucocorticoid represents activation of the hypothalamus-pituitary-adrenal (HPA) system, which is a dominant stress reaction pathway in the body. Subjects were exposed to an alerting odorant, Thesaron®, during a 6h sleep period but not after awakening. Surprisingly, cortisol secretion after awakening was found to be suppressed, as well as during sleep. Exposure of this alerting aroma during sleep may have an impact on cortisol secretion after awakening by suppressing HPA activity after awakening.
