Current research of idiopathic normal pressure hydrocephalus: Pathogenesis, diagnosis and treatment. World J Clin Cases 2023; 11:3706-3713.

Abstract
Idiopathic normal pressure hydrocephalus (iNPH) is caused by impaired cerebrospinal fluid absorption in the elderly; it is a surgically treatable form of dementia. Gait disturbance, dementia, and urinary incontinence are the triad of signs for iNPH. In addition to these clinical findings, imaging studies show characteristic ventricular enlargement. High Evans Index and ‘disproportionately enlarged subarachnoid hydrocephalus’ are other well-known imaging findings of iNPH. If the tap test shows improved symptoms, shunt surgery is performed. The disease was first described by Hakim and Adams in 1965, followed by the publication of the first, second, and third editions of the guidelines in 2004, 2012, and 2020, respectively. Recent studies signal the glymphatic system and classical cerebrospinal fluid (CSF) absorption from the dural lymphatics as aetiological mechanisms of CSF retention. Research is also underway on imaging test and biomarker developments for more precise diagnosis, shunting technique options with fewer sequelae and complications, and the influence of genetics. Particularly, the newly introduced ‘suspected iNPH’ in the third edition of the guidelines may be useful for earlier diagnosis. However, less well-studied areas remain, such as pharmacotherapy in non-operative indications and neurological findings other than the triadic signs. This review briefly presents previous research on these and future issues.

Abstract
Lesch-Nyhan syndrome (LNS) is an inborn error of metabolism. Choreoathetosis, mental retardation and self-harming are the three symptoms. A genetic test that analyses the gene encoding hypoxanthine-guanine phosphoribosyltransferase (HPRT) and blood tests showing hyperuricaemia support the diagnosis. However, the relevance of these test results to clinical symptoms is unclear. A 25 years-old man consulted our hospital for self-injury and choreoathetosis. He had epilepsy and mental retardation. He was also suffering from hyperuricemia and was prescribed allopurinol. These symptoms appeared with the improvement of hyperuricemia. He was suspected to have LNS. Metabolomic analysis of his urine before and after the allopurinol loading test was performed by gas chromatography-mass spectrometry (GC/MS) using dry filter paper urine samples as samples. The results showed that he was LNS.This case suggests that LNS is a condition that causes epileptic seizures and that rapid fluctuations in uric acid levels can cause choreoathetosis and self-harming. GC/MS using dry filter paper urine samples was a simple and valid test. This report also shows that genetic diagnosis opportunities are available to patients who have difficulty attending hospitals with advanced genetic analysis systems in urban areas.

Pneumonia and seizures due to hypereosinophilic syndrome—organ damage and eosinophilia without synchronisation: A case report. World J Clin Cases 2022; 10:6325-6332. [PMID: 35949850 PMCID: PMC9254210 DOI: 10.12998/wjcc.v10.i18.6325] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/03/2022] [Revised: 03/29/2022] [Accepted: 04/30/2022] [Indexed: 02/06/2023] Open
Abstract
BACKGROUND Hypereosinophilic syndrome (HES) is a condition characterized by increased eosinophil proliferation in the bone marrow, as well as tissue eosinophilia, often causing organ damage. The cause of the disease is unknown. Initial symptoms include fatigue, cough, shortness of breath, myalgia, angioedema, fever, and pneumonia. In addition to the respiratory symptoms, damage to the central nervous system can lead to severe seizures. Here, we report a case with pneumonia and complex partial seizures secondary to HES.
CASE SUMMARY A 94-year-old woman was admitted to our hospital for heart failure and bloody stools. After admission, she also showed symptoms of pneumonia. Non-contrast computed tomography of the chest showed pleural effusion and infiltrative shadows. Lower gastrointestinal endoscopy showed multiple ulcers in the sigmoid colon. Blood analyses showed marked eosinophilia (eosinophils 1760/mm3, total leukocytes 6850/mm3). Initial treatment with furosemide 20 mg/d and prednisolone 25 mg/d relieved these symptoms. However, the patient subsequently experienced localised epileptic seizures characterized by bilateral eyelid twitching and eyes rolling upwards, without generalized convulsions, and respiratory arrest occurred. Electroencephalography showed spikes and waves. Non-contrast magnetic resonance imaging of the brain showed extensive periventricular hyperintensity. With administration of levetiracetam 1000 mg/d the epileptic seizures disappeared. However, the patient’s consciousness remained impaired, and her pneumonia worsened again. Two weeks later, she died of pneumonia.
CONCLUSION HES symptoms are variable and atypical, and the level and timing of eosinophilia and organ damage are often discordant.

Kabuki syndrome with ossification of the posterior longitudinal ligament requiring differentiation from Ehlers-Danlos syndrome: a case report with a literature review. BRAZILIAN JOURNAL OF CASE REPORTS 2022.

Abstract
Kabuki syndrome (KS) comprises multiple congenital abnormalities and the main symptoms include characteristic facial features, skeletal and spinal abnormalities, and mental retardation. The estimated incidence of KS is 1 in 32000, and mutations in the KMT2D gene (also known as MLL2) are considered to be involved. The details of such mutations, including the mode of inheritance, are unclear. A 40-year-old woman visited our hospital with back pain and urinary incontinence. The patient had been diagnosed with Ehlers-Danlos syndrome (EDS) in childhood, on the basis of physical findings including hip subluxation. Because of her characteristic facial features, we suspected KS instead. Genetic testing revealed the presence of a rare missense mutation in KDM6A that was suggestive of KS. Computed tomography showed that she had ossification of the posterior longitudinal ligament (OPLL). On the basis of her clinical presentation and genetic mutation in KDM6A, we made a diagnosis of KS with OPLL. Hereditary diseases may share similar clinical characteristics, as in the case of our patient with Kabuki syndrome, who was misdiagnosed in childhood as having an Ehlers-Danlos syndrome involving disordered connective tissue. Physicians should undertake a comprehensive consideration of multiple clinical features when diagnosing a hereditary disease.

Abstract
BackgroundCurrently, five types of Janus kinase inhibitors (JAKis) are used for rheumatoid arthritis (RA) treatment. The number of cases in which multiple JAKis have been prescribed is increasing. However, the real-world efficacy and safety of JAKis and related factors require further evaluation.ObjectivesThe primary objective of this study was to elucidate the impact of past use of disease-modifying anti-rheumatic drugs on RA treatment using JAKis. The secondary objective was to investigate the safety profiles of these agents in a real-world setting.MethodsOf the 303 JAKi-treated patients in the Fukui Ishikawa Toyama Database of RA included in this study, 30 had switched from one JAKi to another (JJ group), 214 switched from a biologic agent to a JAKi (BJ group), and 47 were naïve to either biologics or JAKis (NJ group). We compared baseline factors, treatment response, and JAKi continuation rates among the three groups. Factors related to JAKi discontinuation were assessed using Cox regression analysis. Furthermore, we investigated adverse events and reported them using exposure-adjusted incidence rates (EAIR; incidence rates per 100 patient-years).ResultsData from the 303 cases were analyzed (mean age = 63.6 years; female, 82%; mean RA duration, 176 months). Of the 303 patients, 118, 106, 50, and 29 were treated with tofacitinib, baricitinib, peficitinib, and upadacitinib, respectively, on initial observation. Rate of concomitant use with methotrexate and prednisolone was 52% and 49%, respectively.Regarding efficacy, no significant differences were observed among the three groups in terms of treatment response and JAKi continuation rates, except for the 6-month treatment response between the JJ and NJ groups. Cox regression analysis of the 303 cases revealed that only past use of JAKis during the disease history was significantly associated with JAKi discontinuation. The Kaplan–Meier method showed that patients who previously used JAKis had significantly shorter median JAKi treatment duration than those without such a history (20.9 vs. 54.7 months; p = 0.012). Treatment response was significantly poor in patients who had previously used JAKis, especially 6 months after treatment initiation.In terms of safety, the total exposure period for the 303 cases was 495 person-years, and the total number of adverse events was 161 (EAIR, 32.5). There were 12 cases (EAIR, 2.5) of serious infections, 23 cases (EAIR, 5.1) of herpes zoster, 7 cases (EAIR, 1.4) of malignant tumors, and 4 cases (EAIR, 0.8) of MACE. Adverse events led to JAKi discontinuation in 34 patients (EAIR, 6.9); the main causes of adverse events leading to treatment discontinuation were infectious diseases in 10 cases (EAIR, 2) and neoplasms in 4 cases (EAIR, 0.8). Within 1 year of initiating JAKi therapy, 21 patients discontinued treatment owing to adverse events, which accounted for 27% of the reasons for treatment discontinuation.We also investigated cases of JAKi dose reduction, observed in 42 of the 303 cases. Among them, 10 patients required a re-increase in the JAKi dose, and 13 patients (56.5%) were able to maintain the reduced dose for more than 1 year. The remaining 19 patients were excluded from the analysis because the treatment duration at the lower dose had not exceeded 1 year at the time of data extraction. No difference in disease activity at the time of dose reduction was observed between those who maintained the new dose and those who did not (mean DAS28-CRP: 1.48 ± 0.26 vs. 1.89 ± 0.62).ConclusionPast use of JAKis may contribute to decreased response and continuation rates for JAKi treatment. In this study, conducted in Japan, development of herpes zoster was found to the most frequent adverse event among the priority survey items.AcknowledgementsI have no acknowledgements to declare.Disclosure of InterestsNone declared

Abstract
Brexpiprazole (BPZ) is a novel antipsychotic drug in the category of serotonin-dopamine activity modulators (SDAMs). It is expected to be effective in the treatment of schizophrenia because of its low side effects and its ability to reduce psychosis. However, clinical data in Japan are still insufficient. We prescribed BPZ to 41 schizophrenic patients; 9 of the 41 dropped out and 32 were retrospectively reviewed for psychiatric symptoms using the positive and negative syndrome scale (PANSS). The results showed that there was significant improvement in the total score, the positive scale, the negative scale and the general psychopathology scale, all after 4 weeks. The improvement started after 1 week for the total score, the positive scale and the general psychopathology scale, and after 2 weeks for the negative scale. The results suggest that BPZ is effective not only for positive symptoms in the acute phase, but also for negative symptoms after the subacute phase. Further studies are needed to investigate the efficacy of BPZ by patient's characteristics as well as by sub-items of the PANSS.

Abstract
Because dementia with Lewy bodies (DLB) has various psychiatric symptoms, early diagnosis in patients without parkinsonism is difficult. To reveal associations between regional brain perfusion and psychiatric symptoms in DLB patients without parkinsonism, we quantified brain perfusion using an automated brain perfusion single-photon emission computed tomography analysis program, FineSRT. We statistically analyzed the differences in brain perfusion between groups, divided by the presence or absence of psychiatric symptoms. In DLB patients with depression, there were significant brain perfusion increases in the left angular gyrus and right upper precuneus. In DLB patients with visual hallucinations, there were significant decreases in the left inferior parietal lobule, left superior temporal gyrus, and right primary visual cortex. In DLB patients with auditory hallucinations, there were significant increases in the right middle occipital and right inferior occipital gyri. Our findings provide clues about the pathomechanisms of psychiatric symptoms and may enable early diagnosis of DLB in the future.

Abstract
OBJECTIVES In addition to motor symptoms, patients with Parkinson disease (PD) experience various psychiatric comorbidities, including impulse control disorders (ICDs). Moreover, antiparkinsonian drugs sometimes cause psychiatric symptoms. Antiparkinsonian and antipsychotic drugs are competitive in pharmacodynamics, and psychotropic drugs, including antidepressants, may worsen motor symptoms or induce adverse reactions. Considering this conflicting situation, we examined the effectiveness of electroconvulsive therapy (ECT) on both motor and psychiatric symptoms in PD. METHODS We retrospectively examined 12 PD patients with advanced motor symptoms and drug-resistant psychiatric symptoms, including ICDs, who had undergone ECT. Both before and after ECT, the severity of PD motor symptoms were evaluated using Hoehn and Yahr staging, while psychiatric symptoms were evaluated using the Neuropsychiatric Inventory. The patients' doses of antiparkinsonian and antipsychotic drugs were also assessed before and after ECT. RESULTS Both the mean Hoehn and Yahr and Neuropsychiatric Inventory scores were significantly decreased after ECT. The symptoms of ICDs, which were observed in 5 patients, disappeared following ECT. Improvements in motor symptoms and psychiatric symptoms lasted for more than 1 year in 5 cases and 9 cases, respectively. Furthermore, the daily dose of antiparkinsonian drugs was significantly decreased in 6 cases. CONCLUSIONS Our results demonstrated that ECT was effective for both severe motor symptoms and psychiatric symptoms in advanced PD patients. ECT might be a solution for the conflicting problem of treating both motor and psychiatric symptoms in PD.

Abstract
BACKGROUND Familial idiopathic basal ganglia calcification (FIBGC) is a rare autosomal dominant disorder that causes bilateral calcification of the basal ganglia and/or cerebellar dentate nucleus, among other locations.
CASE SUMMARY The aim of this study is to report 10 cases of FIBGC observed in a single family. Seven patients showed calcification on their computed tomography scan, and all of these patients carried the SLC20A2 mutation. However, individuals without the mutation did not show calcification. Three patients among the 7 with calcification were symptomatic, while the remaining 4 patients were asymptomatic. Additionally, we longitudinally observed 10 subjects for ten years. In this paper, we mainly focus on the clinical course and neuroradiological findings in the proband and her son.
CONCLUSION The accumulation of more case reports and further studies related to the manifestation of FIBGC are needed.

Abstract
The "AMAGAMI" or "incomplete grasping" technique is used to adjust the location of the lung while gently grasping the lung tissue with a stapler. Thoracoscopic segmentectomy requires precise but complex stapling, while the surgical view and the number of available instruments are limited. In the AMAGAMI technique, instead of moving the stapler to the targeted position of the lung tissue, an unlocked stapler is used to hold the lung tissue at an easily accessible position, and the lung tissue can then be slid to the ideal resection line using forceps. To use the AMAGAMI technique effectively, "standing stitches" are very helpful in enabling visualization of the ideal resection lines. Standing stitches are placed along intersegmental lines that have been determined based on the information provided by virtual-assisted lung mapping (VAL-MAP) or other marking techniques; these stiches are usually placed at the corner of the targeted segment and in-between if necessary. Monofilament suture is used for standing stitches, and about 1 cm lengths are left to enable later visualization. As these stitches stick out of the lung surface even when viewed from a tangential angle, the direction of stapling is easily visualized in thoracoscopic surgery. These techniques are particularly useful in challenging segmentectomy requiring complex staple lines, such as S10 segmentectomy, and in surgery with limited instrumental access, such as uniportal thoracoscopic surgery.

Abstract
Anatomical segmentectomy is gathering increasing interest among thoracic surgeons because of increased detection of pulmonary nodules with ground-glass opacity (GGO) as well as an increase in the number of compromised patients. Accurate determination of intersegmental planes is a challenge in anatomical segmentectomy, and multiple methods have been proposed including developing inflation/deflation lines and injecting indocyanine green either intravenously or intrabronchially. Considering resection margins, adding a localization technique to conventional methods, or conducting virtual-assisted lung mapping (bronchoscopic multi-spot dye marking) may be an optional approach for optimal anatomical segmentectomy to identify intersegmental planes and obtain adequate resection margins. To determine optimal resection lines in anatomical segmentectomy, surgeons must also consider oncological validity such as venous and lymph drainage, resection margins, and lung anatomy to avoid complications such as venous congestion, infarction, and air leakage. Although anatomical segmentectomy is an attractive approach to resect small early-stage lung cancer and some metastatic lung tumors, caution is needed to optimally perform this technically demanding surgery.

Sex-specific relevance of diabetes to occlusive vascular and other mortality: a collaborative meta-analysis of individual data from 980 793 adults from 68 prospective studies. Lancet Diabetes Endocrinol 2018; 6:538-546. [PMID: 29752194 PMCID: PMC6008496 DOI: 10.1016/s2213-8587(18)30079-2] [Citation(s) in RCA: 129] [Impact Index Per Article: 21.5] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/15/2017] [Revised: 02/20/2018] [Accepted: 02/26/2018] [Indexed: 01/06/2023]
Abstract
BACKGROUND Several studies have shown that diabetes confers a higher relative risk of vascular mortality among women than among men, but whether this increased relative risk in women exists across age groups and within defined levels of other risk factors is uncertain. We aimed to determine whether differences in established risk factors, such as blood pressure, BMI, smoking, and cholesterol, explain the higher relative risks of vascular mortality among women than among men. METHODS In our meta-analysis, we obtained individual participant-level data from studies included in the Prospective Studies Collaboration and the Asia Pacific Cohort Studies Collaboration that had obtained baseline information on age, sex, diabetes, total cholesterol, blood pressure, tobacco use, height, and weight. Data on causes of death were obtained from medical death certificates. We used Cox regression models to assess the relevance of diabetes (any type) to occlusive vascular mortality (ischaemic heart disease, ischaemic stroke, or other atherosclerotic deaths) by age, sex, and other major vascular risk factors, and to assess whether the associations of blood pressure, total cholesterol, and body-mass index (BMI) to occlusive vascular mortality are modified by diabetes. RESULTS Individual participant-level data were analysed from 980 793 adults. During 9·8 million person-years of follow-up, among participants aged between 35 and 89 years, 19 686 (25·6%) of 76 965 deaths were attributed to occlusive vascular disease. After controlling for major vascular risk factors, diabetes roughly doubled occlusive vascular mortality risk among men (death rate ratio [RR] 2·10, 95% CI 1·97-2·24) and tripled risk among women (3·00, 2·71-3·33; χ2 test for heterogeneity p<0·0001). For both sexes combined, the occlusive vascular death RRs were higher in younger individuals (aged 35-59 years: 2·60, 2·30-2·94) than in older individuals (aged 70-89 years: 2·01, 1·85-2·19; p=0·0001 for trend across age groups), and, across age groups, the death RRs were higher among women than among men. Therefore, women aged 35-59 years had the highest death RR across all age and sex groups (5·55, 4·15-7·44). However, since underlying confounder-adjusted occlusive vascular mortality rates at any age were higher in men than in women, the adjusted absolute excess occlusive vascular mortality associated with diabetes was similar for men and women. At ages 35-59 years, the excess absolute risk was 0·05% (95% CI 0·03-0·07) per year in women compared with 0·08% (0·05-0·10) per year in men; the corresponding excess at ages 70-89 years was 1·08% (0·84-1·32) per year in women and 0·91% (0·77-1·05) per year in men. Total cholesterol, blood pressure, and BMI each showed continuous log-linear associations with occlusive vascular mortality that were similar among individuals with and without diabetes across both sexes. INTERPRETATION Independent of other major vascular risk factors, diabetes substantially increased vascular risk in both men and women. Lifestyle changes to reduce smoking and obesity and use of cost-effective drugs that target major vascular risks (eg, statins and antihypertensive drugs) are important in both men and women with diabetes, but might not reduce the relative excess risk of occlusive vascular disease in women with diabetes, which remains unexplained.

Abstract
Thoracoscopic segmentectomy for the posterior basal segment (S10) and its variant (e.g., S9+10 and S10b+c combined subsegmentectomy) is one of the most challenging anatomical segmentectomies. Stapler-based segmentectomy is attractive to simplify the operation and to prevent post-operative air leakage. However, this approach makes thoracoscopic S10 segmentectomy even more tricky. The challenges are caused mostly from the following three reasons: first, similar to other basal segments, "three-dimensional" stapling is needed to fold a cuboidal segment; second, the belonging pulmonary artery is not directly facing the interlobar fissure or the hilum, making identification of target artery difficult; third, the anatomy of S10 and adjacent segments such as superior (S6) and medial basal (S7) is variable. To overcome these challenges, this article summarizes the "bidirectional approach" that allows for solid confirmation of anatomy while avoiding separation of S6 and the basal segment. To assist this approach under limited thoracoscopic view, we also show stapling techniques to fold the cuboidal segment with the aid of "standing stiches". Attention should also be paid to the anatomy of adjacent segments particularly that of S7, which tends to be congested after stapling. The use of virtual-assisted lung mapping (VAL-MAP) is also recommended to demark resection lines because it flexibly allows for complex procedures such as combined subsegmentectomy such as S10b+c, extended segmentectomy such as S10+S9b, and non-anatomically extended segmentectomy.

In the presence of 5 mol% Pd(OAc)2, 1 equiv. of norbornene, and K2CO3, the reaction of 4-iodo-2-quinolones with tertiary o-bromobenzylic alcohols produced the desired benzopyran-fused 2-quinolones in moderate to high yields. A Catellani-type mechanism involving vinylic C–H cleavage is proposed based on the results of control experiments and density functional theory calculations.

The usefulness of combined brain perfusion single-photon emission computed tomography, Dopamine-transporter single-photon emission computed tomography, and 123 I-metaiodobenzylguanidine myocardial scintigraphy for the diagnosis of dementia with Lewy bodies. Psychogeriatrics 2017; 17:247-255. [PMID: 28130808 DOI: 10.1111/psyg.12227] [Citation(s) in RCA: 10] [Impact Index Per Article: 1.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/10/2016] [Revised: 08/08/2016] [Accepted: 08/31/2016] [Indexed: 11/28/2022]
Abstract
BACKGROUND Current diagnostic criteria recommend neuroimaging as a diagnostic support tool for the clinical diagnosis of dementia with Lewy bodies (DLB). Because DLB causes characteristic impairments and disabilities, such as neuroleptic hypersensitivity, which may significantly increase morbidity and mortality, its prompt and correct diagnosis is very important. The aim of this study was to evaluate the extent to which diagnostic accuracy can be increased by using different combinations of brain perfusion single-photon emission computed tomography (bp-SPECT), 123 I-metaiodobenzylguanidine myocardial scintigraphy (MIBG scintigraphy), and DAT-SPECT. Taking finances and patient burden into consideration, we compared the tests to determine priority. METHODS Thirty-four patients with probable DLB (75.0 ± 8.3 years old; 14 men, 20 women) underwent bp-SPECT, MIBG scintigraphy, and DAT-SPECT. RESULTS Our comparison of three functional imaging techniques indicated that MIBG scintigraphy (79%) and Dopamine-transporter (DAT) SPECT (79%) had better sensitivity for characteristic abnormalities in DLB than bp-SPECT (53%). The combination of the three modalities could increase sensitivity for diagnosis of DLB to 100%. Additionally, the ratio of patients with rapid eye movement sleep behaviour disorder was significantly higher in the positive finding group on MIBG scintigraphy than in the negative finding group. CONCLUSIONS In terms of stand-alone diagnostic means, priority should be placed on MIBG scintigraphy or DAT-SPECT for the diagnosis of DLB. However, our results suggest that the combination of bp-SPECT, MIBG scintigraphy, and DAT-SPECT increased the accuracy of the clinical diagnosis of DLB.

Abstract
Anatomical segmentectomies play an important role in oncological lung resection, particularly for ground-glass types of primary lung cancers. This operation can also be applied to metastatic lung tumors deep in the lung. Virtual assisted lung mapping (VAL-MAP) is a novel technique that allows for bronchoscopic multi-spot dye markings to provide "geometric information" to the lung surface, using three-dimensional virtual images. In addition to wedge resections, VAL-MAP has been found to be useful in thoracoscopic segmentectomies, particularly complex segmentectomies, such as combined subsegmentectomies or extended segmentectomies. There are five steps in VAL-MAP-assisted segmentectomies: (I) "standing" stitches along the resection lines; (II) cleaning hilar anatomy; (III) confirming hilar anatomy; (IV) going 1 cm deeper; (V) step-by-step stapling technique. Depending on the anatomy, segmentectomies can be classified into linear (lingular, S6, S2), V- or U-shaped (right S1, left S3, S2b + S3a), and three dimensional (S7, S8, S9, S10) segmentectomies. Particularly three dimensional segmentectomies are challenging in the complexity of stapling techniques. This review focuses on how VAL-MAP can be utilized in segmentectomy, and how this technique can assist the stapling process in even the most challenging ones.

Abstract
OBJECTIVES The aim of this study is to investigate ipragliflozin as an initial type 2 diabetes (T2DM) drug. METHODS Ipragliflozin 25-50 mg/day monotherapy was performed with drug naïve subjects with T2DM (n=31). As a comparator, 12.5-25 mg/day alogliptin monotherapy was undertaken (n=32). At 3 months, levels of metabolic parameters were compared with those at baseline. FINDINGS 4 subjects discontinued ipragliflozin due to intolerance or adverse events, while none dropped out with alogliptin. At 3 months, similar decreases of HbA1c levels were observed with these 2 drugs (10.21-8.31%, p<0.00001, with ipragliflozin, and 10.08-8.25%, p<0.00001, with alogliptin), however fasting blood glucose (FBG) levels decreased with significant inter-group differences (- 23.5% with iprgliflozin and - 10.8% with alogliptin). While similar increases of homeostasis model assessment (HOMA)-B levels were observed with these 2 drugs, HOMA-R levels significantly decreased only with ipragliflozin (-19.4%, p<0.02). Un-correlative link between HOMA-R and HOMA-B levels at baseline became significantly correlative (R=0.6017, p<0.001) only with ipragliflozin. Significant reductions of body mass index (BMI, -2.6%, P<0.05) were observed with ipragliflozin, however, no correlations between the changes of BMI and those of HbA1c or FBG were noted. CONCLUSIONS These results suggest that ipragliflozin has good glycemic efficacy as an initial therapy in subjects with T2DM, although certain adverse events or tolerability issues are concerned. It improves insulin sensitivity and may restore the impaired beta-cell function. However body weight reduction with ipragliflozin is not associated with its glycemic efficacy.

Abstract
INTRODUCTION Two strategies for selecting neoantigens as targets for non-small cell lung cancer vaccines were compared: (1) an "off-the-shelf" approach starting with shared mutations extracted from global databases and (2) a personalized pipeline using whole-exome sequencing data on each patient's tumor. METHODS The Catalogue of Somatic Mutations in Cancer database was used to create a list of shared missense mutations occurring in more than 1% of patients. These mutations were then assessed for predicted binding affinity to HLA alleles of 15 lung cancer patients, and potential neoantigens (pNeoAgs) for each patient were selected on this basis. In the personalized approach, pNeoAgs were selected from missense mutations detected by whole-exome sequencing of the patient's own samples. RESULTS The list of shared mutations included 22 missense mutations for adenocarcinoma and 18 for squamous cell carcinoma (SCC), resulting in a median of 10 off-the-shelf pNeoAgs for each adenocarcinoma (range 5-13) and 9 (range 5-12) for each SCC. In contrast, a median of 59 missense mutations were identified by whole-exome sequencing (range 33-899) in adenocarcinoma and 164.5 (range 26-232) in SCC. This resulted in a median of 46 pNeoAgs (range 13-659) for adenocarcinoma and 95.5 (range 10-145) for SCC in the personalized set. We found that only one or two off-the-shelf pNeoAgs were included in the set of personalized pNeoAgs-and then in only three patients, with no overlap seen in the remaining 12 patients. CONCLUSIONS Use of an off-the-shelf pipeline is feasible but may not be satisfactory for most patients with non-small cell lung cancer. We recommend identifying personal mutations by comprehensive genome sequencing for developing neoantigen-targeted cancer immunotherapies.

Abstract
Background This retrospective study examined gender differences in non-small cell lung cancer (NSCLC) by analyzing surgical cases at a single institution. Patients and Methods In this study, 735 NSCLC patients who underwent surgery from 1995 to 2010 were included. Clinical and pathological characteristics were retrieved by reviewing charts retrospectively, and variables between genders were compared. Results There were 489 males and 246 females in the study. The percentage of screening-detected lung cancers (83.7%), never smokers (82.9%), adenocarcinoma histology (90.7%), and pathological stage IA (42.7%) was higher in females than that in males (71.2, 8.2, 51.3, and 23.1%, respectively). Female patients had fewer cases of coronary artery disease (2.8%) and fewer pneumonectomy cases (2.0%) than the male patients (7.4 and 5.3%, respectively). The median follow-up period after surgery was 5.9 years. The overall survival rates at 5 years were 57.3% for males and 76.2% for females (p < 0.001, log-rank test). Based on univariate analysis, we report that histology, smoking history, and pathological stage were significant prognostic factors in addition to gender. Based on multivariate analysis, pathological stage III/IV (hazard ratio, 3.60; 95% confidence interval [CI], 2.84-4.54) and female gender (hazard ratio, 0.55; 95% CI, 0.37-0.82) were significant prognostic factors. Subgroup analysis demonstrated that female gender and adenocarcinoma histology were significant positive prognostic factors only in pathological stages I and II (n = 557). Conclusion Female gender as well as pathological stage was favorable prognostic factors. The survival advantage observed in female NSCLC patients was limited to those with cancer at stages I and II.

Abstract
OBJECTIVES The Glasgow Prognostic Score (GPS), which is calculated with C-reactive protein (CRP) and albumin (Alb) values, is a prognostic indicator for various types of cancers. However, its role in lung cancer still remains unclear, and its optimal cut-off values are controversial. Here, we evaluated the significance of the GPS and adjusted GPS (a-GPS) using our institution's cut-off values in patients undergoing resection for primary lung cancer. METHODS We analysed 1043 lung cancer patients who underwent resection between 1998 and 2012. The overall survival (OS) probabilities of the GPS subgroups were estimated using the Kaplan-Meier method and were compared using the log-rank test. The prognostic significance of the GPS and the a-GPS was assessed by the Cox proportional hazards model with clinicopathological variables and inflammation markers, such as the neutrophil-to-lymphocyte ratio (NLR) and the platelet-to-lymphocyte ratio (PLR). The GPS was calculated based on cut-off values of 1.0 mg/dl for CRP and 3.5 g/dl for Alb, as previously reported. The a-GPS was calculated based on cut-off values 0.3 mg/dl for CRP and 3.9 g/dl for Alb, which are the standard thresholds used by our institution. RESULTS The GPS and the a-GPS were correlated with preoperative factors, such as age, sex, smoking status, the NLR and the PLR, and oncological factors, including the pathological stage, histological type and level of lymphovascular invasion. The 5-year OS rates were 82, 55 and 55% with GPS 0, 1 and 2 (1 vs 0: P < 0.01; 2 vs 1: P = 0.66), respectively, and 88, 67 and 59% with a-GPS 0, 1 and 2 (1 vs 0: P < 0.01; 2 vs 1: P = 0.04), respectively. Multivariable analysis revealed that the GPS [1 vs 0, hazard ratio (HR): 1.63, 2 vs 0, HR: 1.44] and the a-GPS (1 vs 0, HR: 2.00, 2 vs 0, HR: 2.10) were independent prognostic factors. The a-GPS classification showed a clearer prognostic distribution than the GPS classification. CONCLUSIONS The GPS is a useful prognostic indicator of the OS in lung cancer surgery. The optimal cut-off values for GPS estimation may need to be re-evaluated.

Abstract
Introduction
Lung cancer is the leading cause of cancer death in Japan, however, it has been difficult to detect and diagnose precisely lung cancer with a diameter less than 1cm to date. The purpose of this study is to investigate clinical application of novel GGT-targeted fluorescence probe for detecting the primary lung cancer in an intraoperative manner.
Methods
As a fluorescence probe for γ-glutamyltranspeptidase (GGT), γ-glutamyl hydroxymethyl rhodamine green (gGlu-HMRG) was used. gGlu-HMRG is non-fluorescent, but is converted to a highly fluorescent hydroxymethyl rhodamine green (HMRG) upon reaction with the enzyme, which tends to accumulate in GGT-overexpressing cancer cells. First, we examined GGT activity of lung cancer cell lines, A549, H460, H441, H82 and H226, by applying gGlu-HMRG and evaluating fluorescence intensities by confocal fluorescence microscopy. We also compared mRNA expression level of GGT1 (one of the subtypes of GGT) by qRT-PCR. Further, by transfecting siRNA targeted to GGT1, we investigated the target of gGlu-HMRG. Next we performed in vivo imaging of orthotopic A549 lung cancer xenograft model in nude mouse to confirm the validity of fluorescence imaging. Finally, we carried out ex vivo fluorescence imaging of 73 human lung cancers and normal lung tissues which were surgically resected, and the fluorescence intensities were analyzed by Receiver Operating Characteristics curve.
Results
A549, H460 and H441 cells with high GGT1 expression could be visualized with high fluorescence intensity after application of gGlu-HMRG within several minutes, whereas H82 and H226 cells with relatively low GGT1 expression could not. We ascertained that the target of gGlu-HMRG was GGT1 by fluorescence imaging and qRT-PCR with lung cancer cell lines transfected with siRNA for GGT1. In lung cancer xenograft model, pleural dissemination, hilar and mediastinal lymph node metastasis and the surface of lung cancer were clearly detected within 15 minutes after topical drip of gGlu-HMRG. We confirm that every fluorescent lesion was adenocarcinoma pathologically. In ex vivo human lung cancer fluorescence imaging, the sensitivity, specificity and accuracy were calculated to be 43.8% (32/73cases), 84.9% (62/73cases) and 64.4% (94/146), respectively. The adenocarcinomas, cancer of female or never smoker were more significantly detected by fluorescence imaging (p<0.05-0.001). Limited to 19 cases of adenocarcinomas, cancer of female and never smoker, sensitivity, specificity, and accuracy were 78.9% (15/19), 73.7% (14/19) and 76.3% (29/38), respectively.
Conclusions
We suggest that intraoperative application of gGlu-HMRG to detect pleural dissemination, small mediastinal lymph nodal metastasis, or other small foci of the lung cancer cells on surgical margin might be feasible when the cancer cells overexpress GGT. Intraoperative application of fluorescence probe is highly expected in near future.

Abstract
We report a case of tracheal resection and reconstruction for a squamous cell carcinoma of the trachea that was found in an 82-year-old male patient who had underwent right lower lobectomy for an adenosquamous cell carcinoma 3.5 years before. He noticed bloody sputum. Chest computed tomography (CT) revealed a 15 mm tumor in the anterior wall of the trachea. A transbronchial biopsy for the tracheal tumor showed a squamous cell carcinoma. Under right thoracotomy, we resected the tumor with 3 tracheal rings. Histologically a squamous cell carcinoma was diagnozed. As there was intraepithelial spread of cancer cells in the oral margin, the tracheal tumor was suspected to be a primary tracheal tumor rather than a metastasis from lung cancer. After the surgery, combination therapies of an external radiation therapy for 50 Gy and brachytherapy 2 times for totally 8 Gy were performed as a postoperative adjuvant therapy. He does not have any signs of recurrence in 1 year and 6 months after the surgery.

Abstract
BACKGROUND Transient receptor potential channel melastatin 8 (TRPM8) is activated by cold temperatures and cooling agents (menthol and icilin). Recent studies showed TRPM8 is expressed in visceral organs and peripheral sensory pathways. However, the role of TRPM8 in visceral hyperalgesia is poorly understood in pathological states such as inflammatory bowel disease. Hence, we investigated the distribution of TRPM8 and its involvement in visceral hyperalgesia in experimental colitis mice. METHODS TRPM8 immunoreactivity was detected using immunohistochemical staining with fluorescein-conjugated tyramide amplification. Visceral hyperalgesia was measured by the intracolonic administration of TRPM8 agonist, WS-12, in control and dextran sodium sulfate (DSS)-induced colitis mice. KEY RESULTS TRPM8 immunoreactivity in the distal colon was much higher than in the transverse and proximal colon under physiological conditions. TRPM8 immunoreactivity markedly increased in the distal colon mucosa of DSS-induced colitis mice compared with control mice. The number of TRPM8 nerve fibers in mucosa of DSS- or 2,4,6-trinitrobenzene sulfonic acid-induced colitis model mice drastically increased compared with control mice. TRPM8 immunoreactivities colocalized with the calcitonin gene-related peptide- and substance P-immunoreactive nerve fibers in the mucosa. Intracolonic administration of WS-12 induced behavioral visceral pain-like responses. The numbers of these responses in the colitis model mice were 3 times higher than in control mice, and were decreased by pretreatment with the TRPM8 channel blocker AMTB. CONCLUSIONS & INFERENCES Increased expression of TRPM8 may contribute to the visceral hyperalgesia of experimental colitis.

Abstract
The methionine sulphoxide reductase A (msrA) gene and its adjacent genetic loci from urease-negative (UN) Campylobacter lari RM2100 and urease-positive thermophilic Campylobacter (UPTC)CF89-12 strains appear to be composed of a msrA structure gene (507 base pairs [bp]) and another five-gene cluster (approximately 6300 bp) in the same strand and direction. A primer pair (F1/R4-msrA) for polymerase chain reaction (PCR) amplification was designed to generate a product of approximately 900 bp of the msrA gene, including its adjacent genetic loci for the thermophilic Campylobacter organisms and generate an amplicon with 16 C. lari isolates (n = 4 for UN C. lari; n = 12 for UPTC). Following direct nucleotide sequencing, sequence analysis and nucleotide sequence alignment analysis, the putative full-length msrA gene from the 16 C. lari isolates showed high nucleotide sequence similarities (91.8-100%) to each other and relatively low similarity (69.3-71.8%) to three reference C. jejuni and C. coli strains. In addition, the msrA gene was transcribed in both the UPTC CF89-12 and NCTC12893 cells using reverse transcription PCR. An immunoreactively positive signal was identified in the UPTC CF89-12 and NCTC12893 cells with anti-UPTC MsrA synthetic peptide antibodies.

Abstract
BACKGROUND Validation of the clinical classification for lung cancer of the 7th edition of the TNM staging system among surgical cases has not been reported previously. METHODS Data of 489 males and 246 females, with a mean age of 67.6 years, who underwent surgical resection for non-small-cell lung cancer were analyzed retrospectively. RESULTS The 5-year survival rate of these patients was 72.2% for clinical stage IA (n = 365), 58.4% for IB (n = 158), 51.2% for IIA (n = 77), 49.1% for IIB (n = 42), 36.8% for IIIA (n = 86), 80% for IIIB (n = 5) and 50% for IV (n = 2). The 5-year survival rate of patients was 100% for pathological stage 0 (n = 2), 86.1% for IA (n = 216), 73.8% for IB (n = 173), 46.1% for IIA (n = 97), 47.2% for IIB (n = 69), 33.3% for IIIA (n = 155), 33.3% for IIIB (n = 3) and 30.9% for IV (n = 20). Prognostic factors included female sex and 70 years of age or younger, as well as adenocarcinoma histology. CONCLUSIONS Deterioration in patient survival was indicated with the exception of stages IIIB and IV, each of which included only a small number of patients. Our study validated the current TNM staging system in surgical cases with regard to both clinical and pathological classifications.

Abstract
PURPOSE The treatment of primary mediastinal germ cell tumors with cisplatin-based chemotherapy followed by surgery is an established practice; however, the prognosis has remained poor. This study reviews the survival outcomes of patients with primary mediastinal germ cell tumors to evaluate the efficacy of our treatment. METHODS We retrospectively reviewed 11 consecutive patients with primary mediastinal germ cell tumors. RESULTS We had treated four patients with seminomas and seven patients with non-seminomas. Ten patients had undergone cisplatin-based chemotherapy. All patients underwent complete resection. Two patients showed a failure of first-line chemotherapy and thus received salvage chemotherapies, including paclitaxel plus ifosfamide followed by high-dose carboplatin plus etoposide (TI-CE) with stem cell transplantation. One of them died of relapse 29 months later; while the other patient remained disease-free for 56 months postoperatively. The postoperative overall 3-year survival rates of the patients with non-seminomas and seminomas were 83 and 100%, respectively. CONCLUSION Complete resection after establishing normalized or decreased at a low-level serum tumor markers plateau plays a crucial role in the management of patients with primary mediastinal malignant germ cell tumors.

A case of wound dual infection with Pasteurella dagmatis and Pasteurella canis resulting from a dog bite -- limitations of Vitek-2 system in exact identification of Pasteurella species. Eur J Med Res 2012; 16:531-6. [PMID: 22112359 PMCID: PMC3351896 DOI: 10.1186/2047-783x-16-12-531] [Citation(s) in RCA: 14] [Impact Index Per Article: 1.2] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Indexed: 11/19/2022] Open
Abstract
Background Pasteurella species, widely known as indigenous orgganisms in the oral and gastrointestinal floras of many wild and domestic animals, are important pathogens in both animals and humans. Human infections due to Pasteurella species are in most cases associated with infected injuries following animal bites. We encountered a rare case of dual infections caused by different two Pasteurella species occurred in a previously healthy 25-year-old female sustaining injury by a dog-bite. Methodology Exudates from the open wound of her dog-bite site, together with the saliva of the dog were submitted for bacteriological examination. Predominantly appearing grayish-white smooth colonies with almost the same colonial properties but slightly different glistening grown on chocolate and sheep blood agar plates were characterized morphologically by Gram's stain, biochemically by automated instrument using Vitek 2 system using GN cards together with commercially available kit system, ID-Test HN-20 rapid panels, and genetically by sequencing the 16S rRNA genes of the organism using a Taq DyeDeoxy Terminator Cycle Sequencing and a model 3100 DNA sequencer instrument. Results The causative isolates from the dog-bite site were finally identified as P. canis and P. dagmatis from the findings of the morphological, cultural, and biochemical properties together with the comparative sequences of the 16S rRNA genes. Both the isolates were highly susceptible to many antibiotics and the patient was successfully treated with the administration of so-called the first generation cephalosporin, cefazolin followed by so-called the third generation cephalosporin, cefcapene pivoxil. The isolate from the dog was subsequently identified as P. canis, the same species as the isolate from the patient. Conclusions To the best of our knowledge, this was the second report of a dual infection with Pasteurella species consisting of P. dagmatis and P. canis resulting from a dog-bite, followed by the first report of dual infections due to P. dagmatis and P. multocida in 1988. Our isolate finally identified as P. dagmatis was misidentified as P. pneumotripica by means of the Vitek 2 system. The species name "P. dagmatis" was not included in the database of the system. It is also important for routine clinical microbiology laboratories to know the limitation of the automated Vitek 2 system for the accurate identification of Pasteurella species especially P. dagmatis. It should be emphasized that there still exists much room for improvement in Vitek 2 system. Significant improvement of Vitek 2 system especially in the identification of Pasteurella species is urgently desired.

Olmesartan, a novel angiotensin II type 1 receptor antagonist, reduces severity of atherosclerosis in apolipoprotein E deficient mice associated with reducing superoxide production. Nutr Metab Cardiovasc Dis 2011; 21:672-678. [PMID: 20399087 DOI: 10.1016/j.numecd.2009.12.016] [Citation(s) in RCA: 14] [Impact Index Per Article: 1.1] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/21/2009] [Revised: 12/10/2009] [Accepted: 12/31/2009] [Indexed: 10/19/2022]
Abstract
BACKGROUND AND AIM Oxidative stress may play an important role in the development of atherosclerosis. Some angiotensin II type 1 (AT(1)) receptor antagonists have the capacity of reducing oxidative stress in addition to the hemodynamic actions. Accordingly, we assessed the hypothesis that olmesartan, a novel AT(1) receptor antagonist, reduced the severity of atherosclerosis in apolipoprotein (apo) E-deficient mice associated with reducing oxidative stress. METHODS AND RESULTS Atherosclerosis was induced in apo E-deficient mice fed a high fat diet. Mice were intraperitoneally treated with an injection of olmesartan (1mg/kg/day) daily over 8 weeks, and were compared with the untreated controls. Blood pressure was not changed significantly by the olmesartan treatment. Fatty streak plaque developed in apo E-deficient mice, and was suppressed in mice that received olmesartan. In addition, olmesartan reduced not only superoxide production but the overload of oxidative stress in aortic walls. There were no significant differences in serum lipid levels between olmesartan-treated and -untreated groups. In vitro study showed that both olmesartan and its active metabolite RNH-6270, an enantiomer of olmesartan, suppressed interferon-γ, macrophage inflammatory protein-2, and thioredoxin (a marker of oxidative stress) concentrations in cultured cells. CONCLUSION Olmesartan may suppress atherosclerosis via reducing not only superoxide production but also the overload of oxidative stress in this animal model.
