Comparison of postoperative biomechanical function between anatomic double-bundle and single-bundle ACL reconstructions using calcium phosphate-hybridized tendon grafts in goats. Orthop Traumatol Surg Res 2017; 103:239-243. [PMID: 28089795 DOI: 10.1016/j.otsr.2016.11.013] [Citation(s) in RCA: 4] [Impact Index Per Article: 0.6] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/27/2016] [Revised: 11/03/2016] [Accepted: 11/24/2016] [Indexed: 02/02/2023]
Abstract
BACKGROUND Calcium phosphate (CaP)-hybridized tendon grafts improved biomechanical function compared with untreated grafts after single-bundle (SB) anterior cruciate ligament (ACL) reconstruction. The purpose of this study was to compare the biomechanical function between anatomic double-bundle (DB) and single-bundle (SB) ACL reconstructions using CaP-hybridized tendon grafts at 6 months postoperatively in goats. HYPOTHESIS We hypothesized that the postoperative biomechanical function in the DB group will be better than that in the SB group. MATERIALS AND METHODS Knee kinematics and in situ forces in the grafts under applied anterior tibial load (ATL) of 50N and internal tibial torque (ITT) of 2.0 Nm at full extension, and 60° and 90° of knee flexion, and the histology of the tendon-bone interface were compared between the DB group (n=6) and SB group (n=6). RESULTS The in situ forces under ATL in the DB group at full extension and 90°of knee flexion were greater than those in the SB group. The in situ forces under ITT in the DB group at full extension and 60°of knee flexion were greater than those in the SB group. The in situ forces on the posterolateral bundle of the grafts under ATL and ITT in the DB group at full knee extension were greater than those on the posterior half of the grafts in the SB group. The histology did not differ significantly between the groups. CONCLUSIONS Although CaP-hybridized tendon grafts were used in both groups, the in situ forces under ATL and ITT in the DB group were greater than those in the SB group at 6 months postoperatively. The posterolateral bundle of the grafts in the DB group acted effectively against both ATL and ITT at full extension. The tendon-to-bone healing was similar in both groups. STUDY DESIGN Controlled laboratory study. Level 2.

Abstract
[Purpose] This study investigated whether it is possible to predict return to home at
discharge from a rehabilitation hospital in Japan using the home care score of patients
with cerebrovascular or osteoarticular disease and low activities of daily living at
admission. [Subjects and Methods] The home care score and functional independent
measurement were determined for 226 patients at admission and at discharge from five
hospitals, and receiver operating characteristic analyses were conducted. [Results] The
home care score cutoff point for the prediction of return to home at admission and at
discharge was 11, and the area under the curve was more than 0.8. The area under the curve
of the home care score was 0.77 for patients with low activities of daily living and
within this group, the probability of return to home was approximately 50%, as predicted
by the functional independent measurement. The home care score increased after receiving
intervention at a rehabilitation hospital. [Conclusion] The home care score is useful for
the prediction of return to home from a rehabilitation hospital, although prediction using
the functional independent measurement is difficult for patients with low activities of
daily living. Moreover, comprehensive interventions provided by the rehabilitation
hospitals improve the ability to provide home care of the patient’s family, which is
assessed by the home care score.

Abstract
BACKGROUND The Fukushima Daiichi and Daini Nuclear Power Plant workers experienced multiple stressors as both victims and onsite workers after the 2011 Great East Japan Earthquake and subsequent nuclear accidents. Previous studies found that disaster-related exposures, including discrimination/slurs, were associated with their mental health. Their long-term impact has yet to be investigated. METHOD A total of 968 plant workers (Daiichi, n = 571; Daini, n = 397) completed self-written questionnaires 2-3 months (time 1) and 14-15 months (time 2) after the disaster (response rate 55.0%). Sociodemographics, disaster-related experiences, and peritraumatic distress were assessed at time 1. At time 1 and time 2, general psychological distress (GPD) and post-traumatic stress response (PTSR) were measured, respectively, using the K6 scale and Impact of Event Scale Revised. We examined multivariate covariates of time 2 GPD and PTSR, adjusting for autocorrelations in the hierarchical multiple regression analyses. RESULTS Higher GPD at time 2 was predicted by higher GPD at time 1 (β = 0.491, p < 0.001) and discrimination/slurs experiences at time 1 (β = 0.065, p = 0.025, adjusted R 2 = 0.24). Higher PTSR at time 2 was predicted with higher PTSR at time 1 (β = 0.548, p < 0.001), higher age (β = 0.085, p = 0.005), and discrimination/slurs experiences at time 1 (β = 0.079, p = 0.003, adjusted R 2 = 0.36). CONCLUSIONS Higher GPD at time 2 was predicted by higher GPD and discrimination/slurs experience at time 1. Higher PTSR at time 2 was predicted by higher PTSR, higher age, and discrimination/slurs experience at time 1.

Abstract
The mechanism of post-vaccination acute disseminated encephalomyelitis (ADEM) has been hypothesized as resulting from vaccination-injected antigens cross-reacting with myelin components, however, a precise etiology has been uncertain. In this report, we describe the case of a 6-year-old Japanese boy who had multiphasic disseminated encephalomyelitis (MDEM), and was positive for both anti-myelin oligodendrocyte glycoprotein (MOG) antibodies and Chlamydophila pneumoniae antibodies. After vaccinations that were the second one for measles and rubella, and the booster immunization for Japanese encephalitis, the patient presented with fever, headache, vomiting, and a change in personality. He was treated with a high-dose of intravenous methylprednisolone in the diagnosis of ADEM. However, these symptoms recurred with different magnetic resonance imaging lesion, and he was diagnosed as MDEM. Retrospective testing for pathogens revealed C. pneumoniae IgM and IgG antibodies, and it was considered that he was infected with C. pneumoniae subclinically. The patient's serum indicated a positive response for the anti-MOG antibody from the onset of the ADEM diagnosis and in all recurrent episodes. Chlamydia species infection has been known to play a role in demyelinating diseases. It is also known that the anti-MOG antibody may be present but not exhibit its pathogenesis in the absence of a cell-mediated inflammatory response; however, the precise mechanism of action of the anti-MOG antibodies is not yet determined. We propose the possibility that post-vaccination demyelinating disease may result from the synergistic effects of a preceding anti-MOG antibody, possibly produced in response to a subclinical Chlamydia species infection.

Abstract
Transthoracic esophagectomy (TTE) is believed to have advantages for mediastinal lymphadenectomy in the treatment of resectable esophageal cancer despite its association with a greater incidence of pulmonary complications and postoperative mortality. Transhiatal esophagectomy is regarded as less invasive, though insufficient in terms of lymph node dissection. With the aim of achieving lymph dissection equivalent to that of TTE, we have developed a nontransthoracic esophagectomy (NTTE) procedure combining a video-assisted cervical approach for the upper mediastinum and a robot-assisted transhiatal approach for the middle and lower mediastinum. We prospectively studied 22 accumulated cases of NTTE and verified feasibility by analyzing perioperative and histopathological outcomes. We compared this group's short-term outcomes with outcomes of 139 equivalent esophageal cancer cases operated on at our institution by conventional TTE (TTE group). In the NTTE group, there were no procedure-related events and no midway conversions to the conventional surgery; the mean operation time was longer (median, 524 vs. 428 minutes); estimated blood loss did not differ significantly between the two groups (median, 385 mL vs. 490 mL); in the NTTE group, the postoperative hospital stay was shorter (median, 18 days vs. 24 days). No postoperative pneumonia occurred in the NTTE group. The frequencies of other major postoperative complications did not differ significantly, nor were there differences in the numbers of harvested mediastinal lymph nodes (median, 30 vs. 29) or in other histopathology findings. NTTE offers a new radical procedure for resection of esophageal cancer combining a cervical video-assisted approach and a transhiatal robotic approach. Although further accumulation of surgical cases is needed to corroborate these results, NTTE promises better prevention of pulmonary complications in the management of esophageal cancer.

Abstract
Background Early bowel obstruction is not a rare complication of gastrectomy, and it may require re-operation in some cases. Case presentation We report the case of a 71-year-old woman who underwent a total gastrectomy with Roux-en-Y reconstruction for a massive gastrointestinal stromal tumor. Postoperatively, she was making good progress and started consuming meals on postoperative day 3. However, on postoperative day 10, she complained of upper abdominal discomfort and nausea. Blood tests showed a mild inflammatory reaction. An upper gastrointestinal series showed obstruction of the elevated jejunum. An abdominal computed tomography scan suggested upper bowel obstruction. Endoscopic observation and repositioning was selected as an effective approach for treatment considering the patient’s clinical condition and background. Upper gastrointestinal endoscopy showed kinking of the elevated jejunum, easy passage through to the anal intestine, and no evidence of mucosal edema, stenosis of the Roux-en-Y anastomosis, bowel ischemia, or necrosis. After endoscopic repositioning, upper gastrointestinal series showed good passage of the jejunum and no evidence of bowel obstruction. At the 6-month follow-up examination, the patient was in good condition and had no complaints. Conclusion We concluded that early endoscopic management should be the effective procedure considered for diagnosis and treatment of early bowel obstruction after gastrectomy in some cases.

Abstract
Abstract
Introduction
In breast cancer, delay in first presentation and self-interruption of continuous treatment are associated with lower survival. It has been suggested that risk factors for such behavioral patterns include poor social support.
Minamisoma City, located within a 30 kilometers radius from Fukushima Daiichi nuclear power plant, has experienced rapid change in social structures following the Great East Japan Earthquake and the subsequent power plant accident. There has been a mass evacuation among young and middle-aged generations for fear of potential irradiation, and this has resulted in the separation of families and friends. These changes may have resulted in a deterioration of social support for residents, which could consequently lead to changed patterns of behavior in diseases such as breast cancer.
Objectives
This study compared the behavioral patterns before and after the disasters in patients with breast cancer in Minamisoma City.
Methods
We retrospectively analyzed data from patients with breast cancer who were diagnosed from January 2008 through March 2015 in the two main cancer centers in Minamisoma City. Demographic and clinical information was extracted from medical records, including age, stage, pathological findings, treatment, and the reason for the first hospital visit. The main outcome was a change of interval from the appearance of initial symptoms to the first hospital visit before and after the disasters. We also assessed whether continuous follow-up was maintained after the disasters. We used an unpaired t-test for numerical variables and a chi-squared test for categorical variables.
Results
A total of 102 and 97 patients were diagnosed with breast cancer before and after the disasters, respectively. There were no statistically significant differences between the 2 groups concerning average age (61 years old vs. 61 years old, p=1), stage 3 or 4 cancer (18% vs. 17%, p=0.81), invasive cancer (92% vs. 93%, p=0.87) and symptomatic patients (75% vs. 74%, p=0.74), respectively. However, after the disasters, there were significant increases in the ratio of patients with more than a one-year delay from the appearance of the initial symptom to the first hospital visit (5.4% vs. 15%, p<0.05). The patients with more than a one-year delay had a significantly higher ratio of advanced stage cancer compared with patients who visited a hospital earlier. Continuous follow-up was maintained in all patients diagnosed after the disasters.
Discussion
The characteristics of patients were not significantly different before and after the disasters, while the ratio of patients with more than a one-year delay of the first hospital visit significantly increased after the disasters. Although information on social capital and other sociodemographic factors was not available, we speculate that poor social support due to changed social structures after the disasters might contribute to delay in first presentation in symptomatic breast cancer patients. Further study is warranted to clarify the factors associated with delayed hospital visits, in order to establish effective health interventions in the aftermath of mass disasters.

Abstract
BACKGROUND The aim of this study was to assess the rate of response to long-term low-dose levetiracetam (LEV) treatment and the clinical factors associated with response. METHODS The response to low-dose LEV of 43 patients with epilepsy (22 male, 21 female; age range, 5-39 years; median age, 13 years) was retrospectively assessed. Patients aged <15 years received <20 mg/kg/day LEV, whereas those aged ≥15 years received <1000 mg/day LEV. Clinical features were compared between responders to low-dose LEV, responders to the recommended dose, and non-responders. RESULTS Of the 43 patients who received low-dose LEV, 13 (30%) showed improvement, defined as seizure cessation or >75% seizure reduction over 6 months for patients with monthly, weekly, and daily seizures; and over 1 year for patients with yearly seizures. Efficacy was maintained for >1 year in 10 (77%) of the 13 patients. Long-term response to low-dose LEV was significantly associated with older age at onset and fewer previous treatments with ineffective anti-epileptic drugs. All patients showing long-term response to low-dose LEV developed only focal seizures. CONCLUSIONS Titration of LEV starting from a low dose may be effective in selected patients. Once patients respond to low-dose treatment, maintenance of the effective dosage may prolong response.

Abstract
Multiple sclerosis (MS) is a syndrome characterized by complex neurological symptoms resulting from demyelinating lesions in the central nervous system. We report a child with a relapse of MS whose only presenting symptom was severe abdominal pain. Dysfunctional intestinal mobility was assessed by abdominal computed tomography. Findings resembled paralytic ileus resulting from peritonitis. However, the patient demonstrated no other symptoms of peritonitis. A T2-weighted magnetic resonance image revealed a new demyelinating lesion localized to thoracic segments T4-T12. The lesion presumably affected autonomic efferents involved in intestinal mobility. Treatment with a pulse of methylprednisolone reduced both abdominal pain and lesion size. To our knowledge, this is the first reported case of a pediatric MS patient with a demyelinating lesion associated with an autonomic symptom of altered intestinal mobility in the absence of neurological symptoms. This atypical presentation of MS highlights the need for physicians' vigilance when treating this patient population.

Abstract
INTRODUCTION In the chronic phase of Hemiconvulsion-Hemiplegia-Epilepsy (HHE) syndrome, developing epilepsy may be intractable. Herein, we report a case where adrenocorticotropic hormone (ACTH) ceased an intractable habitual partial seizure in a patient with HHE syndrome. CASE REPORT A developmentally normal one-year-old girl presented with left focal motor status epilepticus in the clinical course of rotavirus infection. She was diagnosed with HH syndrome. At 4 months after status epilepticus, she developed partial seizures that occurred daily, and which resulted in a stooped posture, head rotation to the right, and contraction of both upper limbs predominantly in the left arm. At this time, she was diagnosed with idiopathic HHE syndrome. Her seizures were not reduced by sodium valproate, clonazepam, clobazam, zonisamide, phenytoin, phenobarbital, topiramate, lamotrigine, or liposteroid. At the age of 7, ACTH therapy was performed. On the 10th day of ACTH therapy, the habitual seizure was ceased. However, partial seizures characterized by left arm contraction then developed. Treatment with 350 mg/day lamotrigine prevented this emerging seizure. She has been free of both seizure types for more than one year, with no serious adverse effects of ACTH therapy. CONCLUSION We suggest that ACTH therapy may be useful for patients with HHE, although further studies are required.

Abstract
BACKGROUND It is unclear whether the incidence of febrile seizure (FS) in children with Down syndrome (DS) is higher or lower than in the general population. In this study, we investigated the incidence of FS in DS patients using mailed questionnaires. METHODS The questionnaires were distributed to parents or caregivers of DS patients attending Osaka Medical College Hospital and six other facilities. The questionnaires were returned by mail from February 2012 to September 2013 from 323 families of DS patients (176 male, 147 female; age range, 3 months-47 years; median age, 5.0 years). To assess the incidence of FS in DS, we performed the following two analyses: (i) we calculated the incidence of FS among DS patients between the ages of 4 and 20 years (n = 199; 113 male, 86 female), and (ii) we extracted families with both DS and healthy siblings between the ages of 4 and 20 years (n = 150; 77 male, 73 female) and compared the incidence of FS in these sibling groups. RESULTS Five DS patients had a past history of FS. The incidence of FS in DS was 2.5%. The incidence of FS was significantly lower in DS patients compared with healthy siblings (P < 0.003; OR, 0.14). CONCLUSION The incidence of FS is lower in DS patients than in the general population.

Abstract
Acute virus-associated encephalopathy induces seizures. Serum N-terminal pro-B-type natriuretic peptide (NTproBNP) levels are elevated following febrile and afebrile seizures. However, the role of NTproBNP in acute virus-associated encephalopathy pathology is unknown. We enrolled 10 patients with acute virus-associated encephalopathy and convulsions (E group: 7 boys, 3 girls; median age, 3.10 ± 1.92 years) and 130 patients with febrile seizure (FS group: 80 boys, 50 girls; median age, 3.23 ± 2.44 years). The E group had significantly higher NTproBNP levels (345 ± 141 pg/mL) compared with the FS group (166 ± 228 pg/mL) (P < .0005). Furthermore, subjects with prolonged seizure within the E group had significantly higher NTproBNP levels (303 ± 107 pg/mL) compared with subjects with prolonged seizure within the FS group (134 ± 100 pg/mL) (P < .005). Our findings suggest that serum NTproBNP levels are increased during the acute phase of acute virus-associated encephalopathy associated with convulsion.

Abstract
Denture-wearing affects the quality and quantity of epithelial cells in the underlying healthy oral mucosa. The physiologic mechanisms, however, are poorly understood. This study aimed to compare histologic changes and cellular responses of an epithelial cell layer to cyclic mechanical pressure-loading mimicking denture-wearing using an organotypic culture system to develop a three-dimensional in vitro oral mucosa model (3DOMM). Primary human oral keratinocytes and fibroblasts were serially grown in a monolayer culture, and cell viability was measured under continuous cyclic mechanical pressure (50 kPa) for 7 days (cycles of 60 min on, 20 s off to degas and inject air). Upon initiation of an air-liquid interface culture for epithelial stratification, the cyclic pressure, set to the mode above mentioned, was applied to the 3DOMMs for 7 days. Paraffin-embedded 3DOMMs were examined histologically and immunohistochemically. In the monolayer culture, the pressure did not affect the viability of oral keratinocytes or fibroblasts. Few histologic changes were observed in the epithelial layer of the control and pressure-loaded 3DOMMs. Immunohistochemical examination, however, revealed a significant decrease in Ki-67 labelling and an increase in filaggrin and involucrin expression in the suprabasal layer of the pressure-loaded 3DOMMs. Pressure-loading attenuated integrin β1 expression and increased matrix metalloproteinase-9 activity. Incomplete deposition of laminin and type IV collagen beneath the basal cells was observed only in the pressure-loaded 3DOMM. Cyclic pressure-loading appeared to disrupt multiple functions of the basal cells in the 3DOMM, resulting in a predisposition towards terminal differentiation. Thus, denture-wearing could compromise oral epithelial homeostasis.

Abstract
There is accumulating evidence that reactive oxygen species are involved in the development of seizures under pathological conditions, and antioxidant treatments are a novel therapeutic approach for epilepsy. The kainic acid (KA) model of induced seizures has been widely used to study temporal lobe epilepsy. However, research on the use of free radical scavengers following KA-induced status epilepticus (SE) is limited. We examined whether antioxidants already used in humans could reduce hippocampal neuronal cell loss, mossy fiber sprouting and the acquisition of hyperexcitability when administered as a single dose after SE. The antioxidant 3-methyl-1-phenyl-2-pyrazolin-5-one (edaravone) (30mg/kg) or N-acetylcysteine (NAC) (30mg/kg) was administered after KA-induced SE ceased by pentobarbital. We evaluated neuronal cell viability 1 week after SE, determined the threshold for seizures induced by inhalation of flurothyl ether 12 weeks after SE, and examined the extent of mossy fiber sprouting 12 weeks after SE. We found that edaravone or NAC prevented neuronal cell loss and mossy fiber sprouting, and increased the threshold for seizures induced by flurothyl ether, even when administered after KA-induced SE. These results demonstrate that a single dose of edaravone or NAC can protect against neuronal cell loss and epileptogenesis when administered after SE ceased by pentobarbital.

Abstract
BACKGROUND AND STUDY AIMS Acute colorectal obstruction (ACO) often accompanies colorectal cancer (CRC) and requires urgent treatment, but achieving elective laparoscopy-assisted colectomy (LAC) is difficult in this setting. The aim of the current study was to assess the clinical outcomes of a transanal tube (Dennis colorectal tube [DCT]) for CRC with ACO, focusing in particular on the impact of the DCT on subsequent elective LAC. PATIENTS AND METHODS Among 1142 patients who underwent surgery for CRC between January 2007 and December 2011, 92 patients with ACO were identified retrospectively. Of these 92 patients, the DCT procedure was performed in 66 patients who fulfilled the indications for DCT, and these patients were included in the study. RESULTS All 66 patients presented with complete obstruction. Technical and clinical success rates for DCT were 93.9 % and 86.4 %, respectively. Perforation after DCT occurred in 4.5 % and the mortality rate was 1.5 %. The rate of LAC was 48.5 %, and the rate of primary stoma was 13.6 %. For curative stage II/III CRC with ACO, DCT resulted in a primary stoma rate of 13.6 %, a one-stage surgery rate of 90.9 %, a LAC rate of 50.0 %, and a 3-year survival rate of 73.1 %. For stage II/III CRC cases with clinical success by DCT, the one-stage surgery rate was 97.4 % and the LAC rate was 56.4 %. CONCLUSIONS DCT achieved a high rate of clinical success and enabled safe one-stage surgery and LAC for CRC with ACO. DCT followed by LAC is proposed as a promising non-invasive strategy for CRC with ACO.

Abstract
We observed a patient with a Saethre-Chotzen-like phenotype with severe neurological features. Saethre-Chotzen syndrome (acrocephalosyndactyly type III; SCS; OMIM #101400) is an autosomal dominant craniosynostosis syndrome characterized by craniofacial and mild limb abnormalities. The phenotypic features of chromosomal microdeletions involving the 7p21.1, where the twist homolog 1 gene (TWIST1) responsible for SCS is located, are recognized as a contiguous gene deletion syndrome with SCS and other phenotypic manifestations. In this study, we identified microdeletions in 4q13.2 and 7p21.1 in a patient with SCS and severe neurological features including developmental delay and autistic behavior. In comparison to other SCS patients with intragenic mutations or small deletions in 7p21.1, neurological features seen in this patient were extremely severe, likely modified by a concurrent deletion of 4q13.2. Both microdeletions were de novo and paternal in origin. Further information on such concurrent chromosomal deletions should be accumulated for better understanding of the mechanism.

Abstract
Since the first paper by Milham et al. suggested that occupational exposure to an electromagnetic field (EMF) could increase the risk of adult leukemia, many epidemiological studies on this problem have been published. In this report the method of meta-analysis was used to summarize the results from these papers quantitatively. The combined relative risk of all leukemia (RR=1.11), as well as acute lymphocytic leukemia (RR=1.38), acute myeloid leukemia (RR=1.07) and chronic lymphocytic leukemia (RR=1.14) increased but not significantly. So far, it is difficult to make a consistent conclusion about the relationship of the occupational exposure to EMF and adult leukemia. Further carefully designed case-control and cohort studies using the more valid means of exposure assessment are required.

Abstract
BACKGROUND Eltrombopag is an oral, non-peptide thrombopoietin receptor agonist that has shown efficacy and safety in chronic immune thrombocytopenia (ITP). However, ethnic differences in eltrombopag exposure have been reported: area under the curve exposure to eltrombopag was 87% greater among ITP patients of East Asian descent than among ITP patients of non-East Asian ITP descent. OBJECTIVES To evaluate the efficacy and safety of eltrombopag by using, in Japanese ITP patients, lower starting (12.5 mg) and maximum (50 mg) doses of eltrombopag than the standard starting (50 mg) and maximum (75 mg) doses approved in the USA and Europe. PATIENTS We examined 23 Japanese patients with previously treated chronic ITP with a platelet count of < 30,000 μL(-1) in a multicenter study comprising a randomized, double-blind, placebo-controlled phase for 6-week evaluation (15 eltrombopag, and eight placebo) and an open-label phase for 6-month evaluation (23 eltrombopag). RESULTS AND CONCLUSIONS The response rate (platelet count of ≥ 50,000 μL(-1) ) at week 6 of the 6-week double-blind phase was 60% in eltrombopag-treated patients and 0% in placebo-treated patients. Ten of 23 patients (43.5%) responded for ≥ 75% of predefined assessment visits during the 6-month open-label phase. Notably, 22% (5/23) of patients responded to 12.5 mg of eltrombopag, which was administered within the first 3 weeks of eltrombopag treatment. Bleeding decreased with eltrombopag treatment as compared with baseline. Eltrombopag was generally well tolerated; one patient experienced a transient ischemic attack on day 9. Eltrombopag (12.5-50 mg) is effective for the management of Japanese patients with chronic ITP (NCT00540423).

Abstract
We report on the mapping of quantum-Hall edge states by quasiresonant photovoltage measurements using a near-field scanning optical microscope. We have observed fine structures near sample edges that shift inward with an increase in magnetic field in accordance with the shift of the positions of the quantum-Hall edge states. We have found a transition from the weak disorder regime where compressible-incompressble strips are visible to the strong disorder regime where fluctuations smear out incompressible strips.

Abstract
Topiramate (TPM) has been shown to be effective for epileptic spasms (ES) in children, but there is little clinical experience with TPM use in Japan. We report three tuberous sclerosis (TS) patients with relapsed ES, who became spasm-free while receiving TPM treatment. All three patients were treated with a starting dose of 0.5 mg/kg/day. The dosage was increased by 0.5 mg/kg/day every 2 weeks. Although the dose of TPM and the period until the relapsed ES subsided differed among these patients, spasm frequency was clearly reduced by a 1 mg/kg/day dose of TPM. Therefore, efficacy against relapsed ES appeared within one month in all three patients. All three became spasm-free, and there have been no ES relapses for more than 5 months to date. In case 2, seizures were well controlled by TPM alone. Cases 2 and 3 were able to discontinue zonisamide treatment. No adverse effects occurred in any of these patients.

Abstract
We examined the effects of a 9-week exercise training (TR) in Wistar male rats, beginning at 4 weeks of age, on the density of endothelial cells (ECs) in epididymal white adipose tissue (WAT) and the mRNA expression of angiogenic factors in adipose tissue stromal vascular fraction (SVF) cells. The number of ECs and mRNA expressions were assessed by lectin staining and real-time reverse transcriptase-polymerase chain reaction, respectively. Compared with control (CR) rats, TR rats gained weight more slowly and had significantly lower final weight of WAT due to the reduction in the size and the number of adipocytes. TR significantly increased the number of ECs per square millimeter and per adipocyte (1.37- and 1.23-fold, respectively) in WAT. This is probably because the number of adipocytes is fewer while the number of ECs is constant in the WAT of TR rats, because the regression line of TR rats for adipocyte number-dependent EC number was shifted toward the left without significant differences in the slopes between groups. TR also induced the upregulation of mRNA expression of vascular endothelial growth factor (Vegf)-A and Vegf-receptor-2 in SVF cells, thereby retaining a constant number of ECs in the WAT.
