Although upper-extremity deep vein thrombosis (UEDVT) is considered rare, its prevalence appears to be increasing, and this may be related to expanding indications for catheter-based interventions. In contrast, few cases have been reported related to strenuous exercise, especially in healthy young adults with thoracic outlet syndrome (Paget-Schroetter syndrome). In contrast to lower-extremity DVT, optimal treatment strategies for UEDVT have not been robustly studied.In this report, we describe a 56-year-old man with primary UEDVT presenting with left arm swelling, paresthesia, and visible collateral veins around the shoulder. Venography revealed thrombotic occlusion of the left subclavian vein. Emergent pharmaco-mechanical catheter-directed thrombolysis (PCDT) was performed, and his left subclavian vein was recanalized. A novel oral anticoagulant was initiated to prevent reclosure. The patient's symptoms subsided without major bleeding complications and at six months, he has no disability for daily activities. Follow-up ultrasonography revealed almost complete patency of the left subclavian vein, after which anticoagulation therapy was terminated.We discuss the role of PCDT in the management of primary UEDVT from the perspective of efficacy and contribution to quality of life.<. Learning objective: UEDVT is relatively rare and has not been examined as extensively as lower-extremity DVT. Nonetheless, patients may have a variety of unpleasant symptoms that substantially decrease quality of life. Pharmaco-mechanical catheter-directed thrombolysis may be effective to reduce clot burden and mitigate the risk of post-thrombotic syndrome. Although there is no current consensus about exact indications for UEDVT patients, the procedure may be more useful than the standard anticoagulant therapy.>. © 2017 Japanese College of Cardiology.

We report a retrospective case series of four patients with genetically confirmed Huntington's disease (HD) and sporadic amyotrophic lateral sclerosis (ALS), examining the brain and spinal cord in two cases. Neuropathological assessment included a polyglutamine recruitment method to detect sites of active polyglutamine aggregation, and biochemical and immunohistochemical assessment of TDP-43 pathology. The clinical sequence of HD and ALS varied, with the onset of ALS occurring after the mid-50's in all cases. Neuropathologic features of HD and ALS coexisted in both cases examined pathologically: neuronal loss and gliosis in the neostriatum and upper and lower motor neurons, with Bunina bodies and ubiquitinimmunoreactive skein-like inclusions in remaining lower motor neurons. One case showed relatively early HD pathology while the other was advanced. Expanded polyglutamine-immunoreactive inclusions and TDP-43- immunoreactive inclusions were widespread in many regions of the CNS, including the motor cortex and spinal anterior horn. Although these two different proteinaceous inclusions coexisted in a small number of neurons, the two proteins did not co-localize within inclusions. The regional distribution of TDP-43-immunoreactive inclusions in the cerebral cortex partly overlapped with that of expanded polyglutamine-immunoreactive inclusions. In the one case examined by TDP-43 immunoblotting, similar TDP-43 isoforms were observed as in ALS. Our findings suggest the possibility that a rare subset of older HD patients is prone to develop features of ALS with an atypical TDP-43 distribution that resembles that of aggregated mutant huntingtin. Age-dependent neuronal dysfunction induced by mutant polyglutamine protein expression may contribute to later-life development of TDP-43 associated motor neuron disease in a small subset of patients with HD. © 2012 Springer-Verlag.

Background: Statins reduce the incidence of cardiovascular events, but no randomized trial has investigated the best statins for secondary prevention. We compared the efficacy of hydrophilic pravastatin with that of lipophilic atorvastatin in patients with acute myocardial infarction (AMI).Methods and Results: A prospective, multicenter study enrolled 508 patients (410 men; mean age, 66.0±11.6 years) with AMI who were randomly assigned to atorvastatin (n=255) or pravastatin (n=253). The target control level of low-density lipoprotein cholesterol (LDL-C) was <100 mg/dl, and patients were followed for 2 years. The primary endpoint was the composite of death due to any cause, non-fatal myocardial infarction, non-fatal stroke, unstable angina or congestive heart failure requiring hospital admission, or any type of coronary revascularization. The primary endpoint occurred in 77 patients (30.4%) and in 80 patients (31.4%) in the pravastatin and atorvastatin groups, respectively (hazard ratio, 1.181; 95% confidence interval: 0.862–1.619; P=0.299), whereas greater reductions in serum total cholesterol and LDL-C were achieved in the atorvastatin group (P<0.001 for each). Changes in hemoglobin A1c, brain natriuretic peptide, and creatinine were not significant between the 2 regimens, and safety and treatment adherence were similar.Conclusions: On 2-year comparison of hydrophilic and lipophilic statins there was no significant difference in prevention of secondary cardiovascular outcome. © 2014, The Japanese Circulation Society

The molecular pathogenesis of non-obstructive azoospermia (NOA) is unclear. Our aim was to identify the genetic susceptibility for NOA in Japanese men by using a combination of transcriptome network analysis and SNP genotyping.We searched for candidate genes using RNA transcriptome network analysis of 2611 NOA-related genes that we had previously reported. We analyzed candidate genes for disease linkage with single nucleotide polymorphisms (SNP) in the genomes of 335 Japanese men with NOA and 410 healthy controls using SNP-specific real-time polymerase chain reaction TaqMan assays.Three candidate genes (NR3C1, YBX2, and BCL2) were identified by the transcriptome network analysis, each with three SNP. Allele frequency analysis of the nine SNP indicated a significantly higher frequency of the NR3C1 rs852977 G allele in NOA cases compared with controls (corrected P = 5.7e-15; odds ratio = 3.20; 95% confidence interval, 2.40-4.26). The other eight candidate polymorphisms showed no significant association.The NR3C1 rs852977 polymorphism is a potential marker for genetic susceptibility to NOA in Japanese men. Further studies are necessary to clarify the association between the NR3C1 polymorphism and alterations of glucocorticoid signaling pathway leading to male infertility.

Previous longitudinal studies have demonstrated that blood pressure measurements at home (HBP) in the wakening- up display stronger predictive power for death, and vascular complications in patients with type 2 diabetes mellitus (T2DM) than clinic blood pressure measurements (CBP). The leading cause of death was cancer. Patients with T2DM have associated with cancer, and high CBP is a risk factor for cancer. Therefore, this study investigated whether HBP or CBP is related to cancer event in patients with T2DM for 10 years. At baseline, 400 Japanese patients with T2DM were classified as hypertensive (HT) or normotensive (NT) based on HBP and CBP. Mean (± SD) duration was 95 ± 35 months. Primary and secondary endpoints were death and cancer, respectively. Differences in outcome between HT and NT were analyzed using survival curves from Kaplan-Meier analysis and log-rank testing. Associated risk factors were assessed using Cox proportional hazards. On basis of HBP, death and event of cancer were significantly higher in HT than in NT. The leading cause of death was cancer. On basis of CBP, there was no significant difference in the incidence of death and event of cancer between patients with HT and NT at baseline. Associated risk factor for cancer was T2DM. Home morning HT may be reflected more keenly state of cancer than clinic HT, which may be superior to clinic NT. When we meet with such patients, it is important that cancer may be one of many causes for morning HT in Japanese patients with T2DM. © Kyuzi Kamoi; Licensee Bentham Open.

A 52-year-old man noticed hardening and swelling of his salivary glands in the summer of 2009. We suspected Mikulicz disease and performed several work-ups. His serum IgG4 level was elevated, and a chest computed tomography scan demonstrated marked thickening of the bronchial wall. A histopathologic examination of a bronchial mucosa biopsy specimen revealed diffuse infiltration of IgG4-positive cells in the submucosal layers, and on this basis we diagnosed IgG4-related disease. After the administration of corticosteroids, the patient's symptoms, his serum IgG4 level and bronchial wall thickening all improved. When encountering a patient with thickening of the bronchial wall, IgG4-related disease should be considered.

A 71-year-old woman was scheduled for arthroscopic knee surgery. Anesthesia was administered with sevoflurane, fentanyl, and rocuronium bromide. Total dose of fentanyl was 200 μg and total dose of rocuronium bromide was 40 mg. After surgery sugammadex 150 mg was given before awakening of the patient and appearance of spontaneous breathing. Immediately after the administration of sugammadex airway pressure increased to 37 cmH 2O, and ventilation became difficult. After naloxone 0.1 mg injection, ventilation improved dramatically. The cause of difficult ventilation was surmised to be upper airway reflex or muscle rigidity caused by reaction to fentanyl. We thought the phenomenon was clearly manifested by rapid recovery from muscle relaxation by injection of sugammadex. Before injection of sugammadex, it is necessary to confirm the effects of anesthetics on the patient's condition.

A successful pregnancy outcome after calcium ionophore A23187 oocyte activation in an infertile couple with a repeated failure of achieving fertilization after ICSI is reported. The secondary infertility couple with oligozoospermia underwent ICSI two times. However, none of the oocytes were fertilized. In the third ICSI attempt, three oocytes after ICSI were activated using calcium ionophore for five minutes. Two of three oocytes thus became fertilized. A successful pregnancy outcome was thereafter achieved with the delivery of a healthy infant without congenital abnormalities. Oocyte activation using calcium ionophore was thus found to be a useful method in a case of repeated failure of fertilization after ICSI.

Primary effusion lymphoma is a rare type of lymphoma which is confined to those body cavities associated with human herpes virus 8 infection in its development. We describe a 93-year-old man with primary effusion lymphoma in the pleura, but who was negative for herpes virus 8 infection. Chest computed tomography revealed bilateral pleural effusion, but did not show any evidence of a tumor mass or lymph node enlargement. Cytological analysis of his pleural effusion revealed atypical lymphoid cells with immunophenotypes which were positive for CD10, CD19 and CD20. Clonal rearrangement of the immunoglobulin-heavy chain gene was detected by Southern blot analysis, and a diagnosis of primary effusion lymphoma was made. Although dyspnea and severe hypoxia developed, accompanied with increased pleural effusion, chemotherapy was not indicated because of his age. We thus tried oral corticosteroid therapy for palliation which resulted in a dramatic, long-term decrease of his pleural effusion. We present a rare case of primary effusion lymphoma effectively controlled by corticosteroid therapy.

Ovarian hyperstimulation syndrome (OHSS) commonly occurs as a complication of ovarian stimulation with gonadotropins. Spontaneous OHSS is an extremely rare event, but can occur as a result of stimulation with pregnancy-derived hCG. We herein report a case of quadruplet pregnancy complicated by OHSS with spontaneous ovulation. The patient had previously undergone ovarian stimulation with clomiphene citrate plus FSH. After that, she conceived spontaneously and developed OHSS after three weeks of amenorrhea. The OHSS was managed by conservative treatment and improved at six weeks of gestation. However, a quadruplet pregnancy became apparent on ultrasound examination. The patient therefore elected to have an induced abortion. Besides the conception in the cycle without administration of exogenous gonadotrophins, the symptoms in this case had the same kinetics as iatrogenic OHSS caused by ovarian stimulation.
