Eight eyes of 7 patients with fungal disease received intravenous injections of 150 to 300 mg micafungin, and samples of blood, cornea, retina-choroid, aqueous humor, and vitreous humor were collected. The micafungin levels in all collected samples exceeded the MICs; however, the levels in the vitreous and aqueous humors were lower. Our findings suggest that intravenous micafungin should be given in combination with intravitreal antifungal agents after vitrectomy in severe cases of intraocular fungal diseases. © 2013 American Society for Microbiology.

To examine the contribution of the FUT2 gene and ABO blood type to the development of Type 1 diabetes in Japanese children.We analysed FUT2 variants and ABO genotypes in a total of 531 Japanese children diagnosed with Type 1 diabetes and 448 control subjects. The possible association of FUT2 variants and ABO genotypes with the onset of Type 1 diabetes was statistically examined.The se2 genotype (c.385A>T) of the FUT2 gene was found to confer susceptibility to Type 1A diabetes in a recessive effects model [odds ratio for se2/se2, 1.68 (95% CI 1.20-2.35); corrected P value = 0.0075].The FUT2 gene contributed to the development of Type 1 diabetes in the present cohort of Japanese children.

Pediatric Diabetes | Year: 2013
Background: The etiology of type 1 diabetes (T1D) is heterogeneous and is according to presence or absence of pancreatic autoantibodies divided into two subtypes: type 1A (autoimmune-mediated) and type 1B (non-autoimmune-mediated). Although several genes have been linked to type 1A diabetes, the genetic cause of type 1B diabetes in Japanese individuals is far from understood. Objective: The aim of this study was to test for monogenic forms of diabetes in auto antibody-negative Japanese children with T1D. Methods: Thirty four (19 males and 15 female) unrelated Japanese children with glutamate decarboxylase (GAD) 65 antibodies and/or IA-2A-negative T1D and diabetes diagnosed at < 5 yr of age were recruited from 17 unrelated hospitals participating in the Japanese Study Group of Insulin Therapy for children and adolescent diabetes (JSGIT). We screened the INS gene and the KCNJ11 gene which encode the ATP-sensitive potassium cannel by direct sequencing in 34 Japanese children with T1D. Results: We identified three novel (C31Y, C96R, and C109F) mutations and one previously reported mutation (R89C) in the INS gene in five children, in addition to one mutation in the KCNJ11 gene (H46R) in one child. These mutations are most likely pathogenic and therefore the cause of diabetes in carriers. Conclusion: Our results suggest that monogenic forms of diabetes, particularly INS gene mutations, can be detected in Japanese patients classified with type 1B. Mutation screening, at least of the INS gene, is recommended for Japanese patients diagnosed as autoantibody negative at <5 yr of age. © 2012 John Wiley & Sons A/S.

Endometrial polyps are very common benign endometrial lesions, but their pathogenesis is poorly understood, except for a few studies indicating the possibility of benign stromal neoplasm. Although the histopathological diagnosis of endometrial polyp on a surgical specimen is straightforward, it is often difficult to differentiate endometrial polyp from endometrial hyperplasia on a biopsy or curettage specimen. Presently, there is no immunohistochemical marker helpful in this differential diagnosis. In this study, we examined p16 expression in 35 endometrial polyps and 33 cases of endometrial hyperplasia that included 16 simple hyperplasias, 14 complex atypical hyperplasias, and 3 complex hyperplasias without atypia. Stromal p16 expression differed significantly between the two groups; it was seen in 31 (89 %) endometrial polyps, but in only 1 (3 %) endometrial hyperplasia. The percentage of p16-positive stromal cells ranged from 10 to 90 % (mean, 47 %) and the positive cells tended to be distributed around glands. Six cases of endometrial hyperplasia within an endometrial polyp were also examined and all cases showed stromal p16 expression. There was no difference in glandular p16 expression between endometrial polyps 33 (94 %) and hyperplasia 27 (82 %). The p16-immunoreactivity was mostly confined to metaplastic epithelial cells in both groups. Stromal p16 expression might be a peculiar characteristic of endometrial polyp and constitute a useful marker for the diagnosis, especially in fragmented specimens from biopsy or curettage. Stromal p16 expression might be a reflection of p16-induced cellular senescence, which has been documented in several benign mesenchymal neoplasms. © Springer-Verlag 2012.

Purpose: To describe a case of autosomal-dominant (AD)-chronic mucocutaneous candidiasis (CMC) with a signal transducer and activator of transcription (STAT) 1 gene mutation, and some of the important complications of this disease such as chronic hepatitis. Methods: We present a 23-year-old woman with CMC, chronic active hepatitis, and hypothyroidism. Her father also had CMC. We performed several immunological analyses of blood and liver samples, and searched for gene mutations for CMC in the patient and her father. Results: We identified the heterozygous substitution c.821 G > A (p.Arg274Gln) in the STAT1 gene of both the patient and her father. The level of β-glucan induced interferon (IFN)-γ in her blood cells was significantly low. Immunoblot analysis detected serum anti-interleukin (IL)-17 F autoantibody. She was found to have increased (low-titer) antibodies related to her hypothyroidism and hepatitis. Her serum IL-18 levels fluctuated with her AST and ALT levels. Liver biopsy revealed CD68-positive cell infiltration and IL-18 expression in the sinusoidal regions. These results suggest that the chronic active hepatitis in this patient may be exacerbated by the excessive IL-18 accumulation caused by recurrent mucocutaneous fungal infection, and decreased IFN-γ production. Conclusions: AD-CMC is known to be caused by a gain-of-function mutation of the STAT1 gene. Chronic active hepatitis is a rare complication of AD-CMC, with currently unknown pathogenesis. It seems that the clinical phenotype in this patient is modified by autoimmune mechanisms and cytokine dysregulation. AD-CMC can be complicated by various immune disorders including autoimmune polyendocrinopathy-candidiasis-ectodermal dystrophy. © 2012 Springer Science+Business Media, LLC.

Endoscopy | Year: 2010
Background and study aims: A small amount of free air, visible on CT but not on plain chest radiography, which appeared following endoscopic submucosal dissection (ESD) of a gastric neoplasm without endoscopically visible perforation, was defined as a transmural air leak, and a prospective, consecutive entry study was performed to determine its incidence and clinical significance. Patients and methods: Between January 2006 and September 2008, ESD was performed for 246 gastric lesions in 246 consecutive patients. Abdominal CT scan was performed 1 day after ESD. In addition, chest radiography and blood biochemistry tests were performed at different time points before and after ESD. Results: Two hundred and nineteen lesions (89%) were curatively removed by ESD. Among the total of 246 patients, we encountered endoscopically visible perforation during ESD in 2 patients (0.8%), and clinically suspected perforation diagnosed by the presence of free air on chest radiography but invisible during ESD in 3 patients (1%), while transmural air leak was observed in another 33 (13%). Air leak occurred in cases where resection size was larger, procedure time longer, and the muscularis propria on the ulcer base was exposed at the end of ESD. Patients with air leaks developed pyrexia at a higher rate than those without (36% vs. 16%, P=0.018). These patients recovered with antibiotics and required no endoscopic or surgical intervention. The presence of an air leak did not affect the duration of hospital stay. Conclusions: A transmural air leak was observed in 13% of the patients undergoing ESD. Larger resection size, prolonged procedure time, and exposure of the muscularis propria on the ulcer base were risk factors for transmural air leak, but the outcome of patients with this complication was good. © Georg Thieme Verlag KG Stuttgart.

Purpose: To report a case of bilateral optic neuropathy following prolonged systemic treat ment with linezolid. Case: A 68-year-old male presented with bilateral impairment of vision since 5 months before. He had been suffering from diabetes mellitus, rheumatic arthritis and cardiac infarction. Findings and Clinical Course: Corrected visual acuity was 0.3 right and 0.4 left. Both eyes were apparently normal. Computed tomography showed sphenoidal, ethmoidal and maxillary sinusitis, leading to prescription of antibacterial drugs. Visual acuity decreased to 0.05 with central scotoma in either eye one month later. The patient disclosed to have been receiving systemic linezolid since 2 years before for in fected right knee. Discontinuation of linezolid was followed by improved visual acuity of 1.5 each 6 weeks later. Conclusion: This case illustrates that toxic optic neuropathy may develop after prolonged systemic use of linezolid.

To determine the preliminary clinical outcomes of image-guided 3-dimensional conformal radiotherapy (IG-3DCRT) for limited but variably-sized brain metastases (BM). Sixty-two lesions in 24 patients were retrospectively evaluated; out of these patients 75% were =65 years of age, and 37.5% were categorized into recursive partitioning analysis (RPA) class 3. The median value for the maximum diameter of the lesions was 19 mm (range=4-72 mm). The median sole treatment dose was 36 Gy in 10 fractions. The median survival durations after IG-3DCRT were 12.0 months and 3.2 months for patients categorized into RPA classes ≤2 and 3, respectively. Local recurrences occurred in two lesions with a 6-month local control probability of 93.0%. Major toxicities included radiation necrosis in two patients. IG-3DCRT is feasible even for patients with limited BM who are categorized into RPA class 3, and confers clinical outcomes comparable to those of stereotactic radiosurgery, including excellent local control and minimal toxicity even for large tumors.

It is generally known that heat shock protein 27 (HSP27) is phosphorylated through p38 mitogen-activated protein (MAP) kinase. We have previously reported that HSP27 is released from human platelets associated with collagen-induced phosphorylation. In the present study, we conducted an investigation into the effect of thrombin receptor-activating protein (TRAP) on the release of HSP27 in platelets in type 2 diabetes mellitus (DM) patients. The phosphorylated-HSP27 levels induced by TRAP were directly proportional to the aggregation of platelets. The levels of phosphorylated-HSP27 (Ser-78) were correlated with the levels of phosphorylated-p38 MAP kinase and phosphorylated-Akt in the platelets stimulated by 10 M TRAP but not with those of phosphorylated-p44/p42 MAP kinase. The levels of HSP27 released from the TRAP (10 M)-stimulated platelets were correlated with the levels of phosphorylated-HSP27 in the platelets. The released platelet-derived growth factor-AB (PDGF-AB) levels were in parallel with the HSP27 levels released from the platelets stimulated by 10 M TRAP. Although the area under the curve (AUC) of small aggregates (9-25 m) induced by 10 M TRAP showed no significant correlation with the released HSP27 levels, AUC of medium aggregates (25-50 m), large aggregates (50-70 m) and light transmittance were significantly correlated with the released HSP27 levels. TRAP-induced phosphorylation of HSP27 was truly suppressed by deguelin, an inhibitor of Akt, in the platelets from a healthy subject. These results strongly suggest that TRAP-induced activation of Akt in addition to p38 MAP kinase positively regulates the release of phosphorylated-HSP27 from human platelets, which is closely related to the platelet hyper-aggregation in type 2 DM patients.
