| Abstract | Correct screw placement is especially difficult in the upper thoracic vertebrae. At the cervicothoracic junction (C7-T2), problems can arise because of the narrowness of the pedicle and the difficulty of using a lateral image intensifier there. Other upper thoracic vertebrae (T3-6) pose a problem for screw insertion also because of the narrower pedicle. We inserted 154 pedicle screws into 78 vertebrae (C7 to T6) in 38 patients. Screws were placed using intraoperative data acquisition by an isocentric C-arm fluoroscope (Siremobile Iso-C3D) and computer navigation. Out of 90 pedicle screws inserted into 45 vertebrae between C7 and T2, 87 of the 90 (96.7%) screws were classified as grade 1 (no perforation). Of 64 pedicle screws inserted into 33 vertebrae between T3 and T6, 61 of 64 (95.3%) screws were classified as grade 1. In this study, we reduced pedicle screw misplacement at the level of the C7 and upper thoracic (T1-6) vertebrae using the three-dimensional fluoroscopy navigation system. |

| Abstract | We investigated the link between renal function as evaluated by estimated glomerular filtration rate (eGFR) and metabolic syndrome in Japanese. A total of 11,711 Japanese subjects, aged 20-79 years, were recruited in a cross-sectional clinical investigation. From this group, we further investigated the data on 1,576 subjects. eGFR was calculated using serum creatinine (Cr), age and sex. The diagnosis of metabolic syndrome was based on the Japanese criteria. In the first analysis, 288 men (7.8%) and 498 women (6.2%) were diagnosed with reduced eGFR (<60ml/min). eGFR was not correlated with anthropometric, body composition parameters in either sex. In the second analysis, in subjects without medications, 132 men (20.8%) and 15 women (1.6%) were diagnosed with metabolic syndrome. eGFR was lower in men with abdominal obesity and in women with hypertension was than in those without. Among Japanese not taking medications, lower eGFR may be a characteristic of men with abdominal obesity and of women with hypertension. |

| Abstract | We examined whether the preoperative time required for the Timed "Up and Go" (TUG) test could predict the risk for deep venous thrombosis (DVT) in patients with hip osteoarthritis after total hip arthroplasty (THA). Eighteen patients with DVT diagnosed by venography were selected, and 18 without DVT of the same age and sex and with the same operated side as the DVT group were selected as a control group. We evaluated the 5 preoperative factors that might affect the occurrence of DVT complications, as follows:disease duration, body mass index, serum total cholesterol, subjective pain evaluated by the visual analog scale, and TUG. The JOA hip score (pain, range of motion, walking ability, and daily life) was also evaluated before surgery. As a postoperative factor, we checked the postoperative day when weight-bearing was initiated. As a result, TUG (DVT, 18.4+/-4.0 sec vs. control, 15.0+/-3.2 sec;p0.01) was only significantly different between the 2 groups. The ROC curve revealed that the cut-off point of 15.3 sec in preoperative time for TUG was sensitive (83.3%) and specific (61.1%) for DVT after THA (odds ratio7.0;95% confidence interval, 1.6-30.8). These results suggested that low preoperative ambulatory ability in patients with hip osteoarthritis might be associated with DVT after THA. An improvement in TUG before surgery might contribute to a decrease in the occurrence of DVT after THA. |

| Abstract | Plain X-ray radiography is frequently used for the diagnosis of developmental dislocation of the hip (DDH). The aim of this study was to construct a diagnostic support system for DDH based on clinical findings obtained from the X-ray images of 154 female infants with confirmed diagnoses made by orthopedists. The data for these subjects were divided into 2 groups. The Min-Max method of nonlinear analysis was applied to the data from Group 1 to construct the diagnostic support system based on the measurement of 4 items in X-ray images:the outward displacement rate, upward displacement rate, OE angle, and alpha angle. This system was then applied to the data from Group 2, and the results were compared between the 2 groups to verify the reliability of the system. We obtained good results that matched the confirmed diagnoses of orthopedists with an accuracy of 85.9%. |

| Abstract | We studied clinical and radiographic features of interstitial lung disease (ILD) during trimethoprim/sulfamethoxazole (TMP/SMX) administration. Ten patients who had received prednisolone treatment for underlying diffuse pulmonary disease showed various ILDs after introduction of TMP/SMX. The radiographic features of the ILDs were not consistent with infectious disease or exacerbation of the underlying disease, and these diagnoses were excluded radiographically and on clinical grounds during the differential diagnosis of the ILDs. These ILDs emerged relatively early after introduction of TMP/SMX, which is consistent with the former case report of drug-induced ILD (DI-ILD) caused by TMP/SMX. Therefore DI-ILDs caused by TMP/SMX were suspected in these cases. In most of these cases, the ILDs were clinically mild and disappeared immediately although administration of TMP/SMX was continued. |

| Abstract | Physicians should educate patients with sexually transmitted infections (STIs) on measures to prevent reinfection and should also undertake human immunodeficiency virus (HIV) testing after diagnosis of STIs. These preventive measures are important, but it is not known to what extent these procedures are followed in Japan. We conducted a cross-sectional study to investigate the proportion of patients with STIs who received appropriate management from physicians, namely recommendation of HIV testing, encouragement of condom use and examination and/or treatment of sexual partners, to elucidate the factors affecting institution of each measure. From a mailshot of 566 physicians, 409 (72.3%) responded, with 176 diagnosing an STI in 967 patients. The proportions applying the 3 measures were low (recommendation of HIV testing:27.0;encouragement of condom use:64.8%;examination of sexual partners:17.5%), and were related to the sex of the patients and numbers of patients diagnosed by the physicians. Female patients received better care than male patients, particularly with respect to recommendation of HIV testing (odds ratio:2.82). Physicians who diagnosed more than 20 STI patients tended not to provide appropriate management. These findings suggest the necessity for better physician management of patients for effective prevention of STIs. |

| Abstract | In an attempt to prepare egg yolk immunoglobulin (IgY) to treat and prevent cholera, hens were immunized by a mixture of heat- or formalin-killed Vibrio cholerae O1 and O139 organisms, or by the recombinant cholera toxin B subunit (CTB). The IgYs were partially purified from egg yolk and orally administered to suckling mice before or after challenge with live O1 or O139 cells. The anti-O1 and O139 IgYs and the mixture of either IgY with anti-CTB IgY significantly protected the occurrence of cholera caused by both O1 and O139 infection. Since large amounts of IgY can be prepared very easily and at low cost, this seems to be a useful procedure for preventing and treating cholera. |

| Abstract | Epigenetics is an essential mechanism to control gene expression and fundamental cellular processes. DNA methylation in CpG-rich promoters correlates with gene silencing. Histone modification including histone acetylation and deacetylation determines the stability of the chromatin structure. Condensed chromatin (heterochromatin), which has a higher-order histone-DNA structure, prevents the access of transcriptional activators to their target genes. The fundamental unit of eukaryotic chromatin consists of 146 bp of DNA wrapped around a histone octamer. Posttranslational modifications of the histone tail and the chromatin remodeling complex disrupt histone-DNA contacts and induce nucleosome mobilization. Histone acetylation of specific lysine residues in the histone tail plays a crucial role in epigenetic regulation. Histone acetylation is a dynamic process regulated by the antagonistic actions of 2 families of enzymes - the histone acetyltransferases (HATs) and the histone deacetylases (HDACs). The balance between histone acetylation and deacetylation serves as a key epigenetic mechanism for transcription factor-dependent gene expression and the developmental process. We review emerging evidence that DNA methylation, histone acetylation modified by HAT and/or HDAC, and transcription factor-associated molecules contribute to a mechanism that can alter chromatin structure, gene expression, and cellular differentiation during chondrogenesis. |
