BACKGROUND Non-operative management for patients with fistula-in-ano in infancy using a traditional herbal medicine Ginseng and Tang-kuei Ten Combination (GTTC) is described. METHODS A total of 22 patients with peri-anal abscess or fistula-in-ano were treated with GTTC. Eighteen patients showed no improvement using the conventional non-operative(More)
Acute encephalitis with refractory, repetitive partial seizures (AERRPS) is a neurologic syndrome characterized by extraordinarily frequent and refractory partial seizures, which immediately evolve into refractory epilepsy. To elucidate the pathophysiology of AERRPS, we performed an immunologic study of an affected boy, revealing decreased natural killer(More)
Light aqueduct: Periodic mesoporous organosilica exhibits strong light absorption due to densely packed organic chromophores within the pore walls. Light energy absorbed by 125 biphenyl groups in the pore walls is funneled into a single coumarin 1 molecule in the mesochannels with almost 100% quantum efficiency, and results in significant enhancement of(More)
BACKGROUND Colorectal sessile serrated adenoma/polyps (SSA/Ps) are characterized by asymmetrical distribution of Ki67-positive cells, which varies among crypts and involves the crypt length to a variable extent; the pattern has been designated as aberration of crypt cell compartmentalization. The regenerating gene (REG) Iα is a cell growth and/or(More)
BACKGROUND Currently, there is no effective therapy for advanced gastric cancer. In this study, we investigated whether protein expression of CXCL12 and/or its receptor CXCR4 is associated with clinicopathological features and/or survival of gastric cancer. MATERIALS AND METHODS Primary tumor specimens from patients (n=137) with pathologically-confirmed(More)
A 9-year-old male presented with a renal tumor that showed a cystic structure with calcification on computed tomography. A pathological analysis of the resected tumor suggested clear cell sarcoma of the kidney (CCSK). Thus, this patient suffered atypical CCSK with significant calcification and gross necrosis. A novel chromosomal abnormality was also(More)
We observed the changes in serum levels of interleukin 6 (IL-6) and C-reactive protein (CRP) in a patient with hepatoblastoma exhibiting thrombocytosis. The concomitant changes of IL-6 and CRP concentrations after the initiation of chemotherapy, in the absence of infection, suggested that the IL-6, which is synthesized in hepatoblastoma cells and induces(More)
The patient was a 2-month-old female infant born at 41 weeks and 2 days of gestation presenting multiple arthrogryposis, severe muscle hypotonia and respiratory distress with difficulty in feeding. She suffered from repeated complications with aspiration pneumonia. On admission to our hospital, she exhibited fasciculation and absence of deep tendon(More)
We had experience with a case of mesenchymal hamartoma of the chest wall (MHCW) with fluorodeoxyglucose (FDG) uptake on positron emission tomography/computed tomography (PET/CT). We reported the first case of asymptomatic MHCW in a child with preoperative PET/CT. Mesenchymal hamartoma of the chest wall is a rare benign tumor that usually presents as a(More)
