Maffucci syndrome is a nonhereditary disorder caused by somatic mosaic isocitrate dehydrogenase 1 or 2 (IDH1 or IDH2) mutations and is characterized by multiple enchondromas along with hemangiomas. Malignant transformation of enchondromas to chondrosarcomas and secondary neoplasms, such as brain tumors or acute myeloid leukemia, are serious complications. A 15-year-old female with Maffucci syndrome developed B-cell precursor acute lymphoblastic leukemia (BCP-ALL). A somatic mutation in IDH1 was detected in hemangioma and leukemic cells...

  The number of patients with nontuberculous mycobacterial (NTM) disease is reportedly increasing both in Japan and worldwide. NTM diseases are classified into disseminated and pulmonary diseases based on their clinical characteristics. These two types of NTM diseases are thought to be controlled by different mechanisms. Disseminated NTM disease is caused by a defect in signal transduction of Th1 cellular immune responses, including the IFN-γ/IL-12 axis. The precise molecular mechanisms of disseminated NTM disease are understood in detail...

  CD271 is common stem cell marker for the epidermis and dermis. We assessed a kinetic movement of epidermal and dermal CD271(+) cells in the wound healing process to elucidate the possible involvement with chronic skin ulcers. Epidermal CD271(+) cells were proliferated and migrated from 3 days after wounding. Purified epidermal CD271(+) cells expressed higher TGFβ2 and VEGFα transcripts than CD271(-) cells. Delayed wound healing was observed in the aged mice compared with young mice. During the wound healing process, the peak of dermal CD271(+) cell accumulation was delayed in aged mice compared with young mice...

Parkinson's disease (PD) is the second most common neurodegenerative disorder that is characterized by progressive movement disability and a variety of non-motor symptoms. The neuropathology of PD consists of the loss of dopaminergic neurons in the midbrain and the appearance of neuronal inclusions called Lewy bodies, which contain insoluble α-synuclein, a relatively small protein originally identified in association with synaptic vesicles in the presynaptic nerve terminals. Drugs that replenish dopamine can partly alleviate the motor symptoms, but they do not cure the disease itself...

BACKGROUND: Multiple metal stents (multi-MS) in the perihilar bile duct often develop dysfunction in an unexpectedly short period. AIMS: This study is aimed to identify the risk factors for shorter patency of multi-MS. METHODS: Of 97 patients who underwent multi-MS placement, 68 patients were followed-up for >28 days were retrospectively analyzed. Univariate analyses with the log-rank test was performed on 20 factors, including two newly defined classifications of cholangiography: the R classification, which classifies the rough image (localized type [R1] or spreading type [R2]); and the S classification, which classifies the surface texture (soft irregularity [S1], solid irregularity [S2], or smooth [S3])...

We herein reported a 4-month-old boy with transplantation-associated atypical hemolytic uremic syndrome (TA-aHUS) who was successfully treated with eculizumab. The patient diagnosed with type 3 of familial hemophagocytic lymphohistiocytosis underwent cord blood transplantation. After transplantation, he developed TA-aHUS, but plasma exchanges were unsuccessful. We identified deletions in CFH-related gene 1 (del-CFHR1) by the multiplex ligation-dependent probe amplification testing procedure and CFH autoantibodies...

Bone is maintained by a balance between bone formation and resorption. This remodeling is controlled by a wide variety of systemic and local factors including hormones, cytokines and mechanical stresses. The present in vitro study examined the impact of medium volume, using 0.4, 0.6, 0.8, 1.0, 1.5 and 2.0 ml/well in a 24‑well plate, on the differentiation of osteoblasts and osteoclasts. There were no differences in the alkaline phosphatase activity of osteoblasts amongst the groups; however, the area of mineral deposition was decreased in a media volume‑dependent manner...

Infrared (IR) p-polarized multiple-angle incidence resolution spectrometry (pMAIRS) is a powerful tool for analyzing the molecular orientation in an organic thin film. In particular, pMAIRS works powerfully for a thin film with a highly rough surface irrespective of degree of the crystallinity. Recently, the optimal experimental condition has comprehensively been revealed, with which the accuracy of the analytical results has largely been improved. Regardless, some unresolved matters still remain. A structurally isotropic sample, for example, yields different peak intensities in the in-plane and out-of-plane spectra...

Tetrahydrobiopterin (BH4) is a common coenzyme of phenylalanine-, tyrosine-, and tryptophan hydroxylases, alkylglycerol monooxygenase, and NO synthases (NOS). Synthetic BH4 is used medicinally for BH4-responsive phenylketonuria and inherited BH4 deficiency. BH4 supplementation has also drawn attention as a therapy for various NOS-related cardio-vascular diseases, but its use has met with limited success in decreasing BH2, the oxidized form of BH4. An increase in the BH2/BH4 ratio leads to NOS dysfunction. Previous studies revealed that BH4 supplementation caused a rapid urinary loss of BH4 accompanied by an increase in the blood BH2/BH4 ratio and an involvement of probenecid-sensitive but unknown transporters was strongly suggested in these processes...

RATIONALE: Bronchiolitis is the most common lower respiratory infection in infants; however, it remains unclear which infants with bronchiolitis will develop severe illness. In addition, while emerging evidence indicates associations of the upper-airway microbiome with bronchiolitis severity, little is known about the mechanisms linking airway microbes and host response to disease severity. OBJECTIVES: To determine the relations among the nasopharyngeal airway metabolome profiles, microbiome profiles, and severity in infants with bronchiolitis...

BACKGROUND: Bilateral adrenalectomy is performed in cases with infantile-onset Cushing syndrome due to bilateral adrenal hyperplasia in McCune-Albright syndrome (MAS) because severe Cushing syndrome with heart failure and liver dysfunction can have a lethal outcome. This procedure can completely ameliorate hypercortisolism, although lifetime steroid replacement therapy and steps to prevent adrenal crisis are necessary. Recently, the efficacy of unilateral adrenalectomy has been reported in adult cases of bilateral macronodular adrenal hyperplasia, but there is no consensus regarding the appropriate surgical treatment for bilateral adrenal hyperplasia in MAS...
