Abstract
We describe a 40-year-old living-donor renal-transplant recipient who underwent successful ureterolithotripsy. He had been on hemodialysis for >15 years pre-transplant and underwent ureteroureterostomy along with the surgery. One year post-transplant, ultrasound examination demonstrated hydronephrosis, and CT showed a 6-mm ureteral calculus at the ureteroureterostomy site. No pain and no elevated serum creatinine were present. As the ureter was easily accessed, we performed a ureterolithotripsy, which would confirm whether a suture caused the calculus. Despite ureteral tortuosity, laser stone fragmentation succeeded. The calculus was completely removed with an antegrade guidewire. Mild postoperative ureteral stenosis resolved with a temporary ureteral stent without balloon dilation. Ureterolithotripsy is effective even in renal transplant recipients with ureteroureterostomy.

Abstract
We report the case of a 58-year-old Japanese man with bilateral synchronous renal cell carcinoma (RCC). The diameters of the right and left tumors were 56 and 69 mm, respectively. Both tumors were endophytic. Cryoablation with prophylactic embolization was performed for the left tumor, and 1 month later, a right open partial nephrectomy was performed. No recurrence was observed during a 16-month follow-up, and the serum creatinine level has been stable. The prognosis of bilateral synchronous RCC is better than that of dialysis patients. The novel approach of combining cryoablation and partial nephrectomy can achieve good cancer control and renal function in bilateral RCC.

Abstract
A 38-year-old woman with a 2.7-cm left ureteral stenosis requiring chronic ureteral stent exchange elected to undergo robotic renal autotransplantation. Left ureteropelvic junction obstruction (UPJO) was also suspected. Robotic donor nephrectomy contributed to the fine dissection for desmoplastic changes. The kidney was removed through a Gelport and examined on ice. UPJO was not seen. An end-to-side robotic anastomosis was created between the renal and external iliac vessels. The console time was 507 min, and the warm ischemia time was 4 min 5 sec. She became stent-free. Robotic renal autotransplantation is a new, minimally invasive approach to renal preservation.

Abstract
INTRODUCTION Management of pregnancy and delivery of a patient with a history of myelomeningocele requires a multidisciplinary team approach. CASE REPORT We report a case of pregnancy and delivery by a patient who had a history of myelomeningocele surgical repair, ventriculoperitoneal (VP) shunt, and bladder augmentation enterocystoplasty. Regarding types of delivery style, anesthesiologists recommended a Cesarean section under general anesthesia. However, urologists recommended a vaginal delivery because they were concerned that she would require a nephrostomy because of severe adhesion between her uterus and the neobladder if she had a Cesarean section. DISCUSSION In a pregnant myelomeningocele patient with a VP shunt, neurosurgeons are expected to manage the VP shunt during pregnancy and delivery. The possible types of delivery style and the best options based on the neurological deficit should be discussed together with a medical team.

Abstract
BACKGROUND Recent preclinical and phase I studies have reported that rebamipide decreased the severity of chemoradiotherapy-induced oral mucositis in patients with oral cancer. This placebo-controlled randomized phase II study assessed the clinical benefit of rebamipide in reducing the incidence of severe chemoradiotherapy-induced oral mucositis in patients with head and neck cancer (HNC). METHODS Patients aged 20-75 years with HNC who were scheduled to receive chemoradiotherapy were enrolled. Patients were randomized to receive rebamipide 2% liquid, rebamipide 4% liquid, or placebo. The primary endpoint was the incidence of grade ≥ 3 oral mucositis determined by clinical examination and assessed by central review according to the Common Terminology Criteria of Adverse Events version 3.0. Secondary endpoints were the time to onset of grade ≥ 3 oral mucositis and the incidence of functional impairment (grade ≥ 3) based on the evaluation by the Oral Mucositis Evaluation Committee. RESULTS From April 2014 to August 2015, 97 patients with HNC were enrolled, of whom 94 received treatment. The incidence of grade ≥ 3 oral mucositis was 29% and 25% in the rebamipide 2% and 4% groups, respectively, compared with 39% in the placebo group. The proportion of patients who did not develop grade ≥ 3 oral mucositis by day 50 of treatment was 57.9% in the placebo group, whereas the proportion was 68.0% in the rebamipide 2% group and 71.3% in the rebamipide 4% group. The incidences of adverse events potentially related to the study drug were 16%, 26%, and 13% in the placebo, rebamipide 2%, and rebamipide 4% groups, respectively. There was no significant difference in treatment compliance among the groups. CONCLUSIONS The present phase II study suggests that mouth washing with rebamipide may be effective and safe for patients with HNC receiving chemoradiotherapy, and 4% liquid is the optimal dose of rebamipide.

Abstract
BACKGROUND Margin status with resection of colorectal liver metastasis (CRLM) was an important prognostic factor in the years before the introduction of biological chemotherapy. This study examined outcomes following CRLM resection in patients who received neoadjuvant chemotherapy with or without the monoclonal antiangiogenic antibody bevacizumab. METHODS Patients who underwent surgery for CRLM at the Johns Hopkins Hospital between 2000 and 2015 were identified from an institutional database. Data regarding surgical margin status, preoperative bevacizumab administration and overall survival (OS) were assessed using multivariable analyses. RESULTS Of 630 patients who underwent CRLM resection, 417 (66·2 per cent) received neoadjuvant chemotherapy with (214, 34·0 per cent) or without (203, 32·2 per cent) bevacizumab. The remaining 213 (33·8 per cent) did not receive neoadjuvant chemotherapy. Univariable analysis found that positive margins were associated with worse 5-year OS than R0 resection (36·2 versus 54·9 per cent; P = 0·005). After dichotomizing by the receipt of preoperative bevacizumab versus chemotherapy alone, the prognostic value of pathological margin persisted among patients who did not receive preoperative bevacizumab (5-year OS 53·0 versus 37 per cent after R0 versus R1 resection; P = 0·010). OS was not significantly associated with margin status in bevacizumab-treated patients (5-year OS 46·8 versus 33 per cent after R0 versus R1 resection; P = 0·081), in whom 5-year survival was slightly worse (presumably reflecting more advanced disease) than among patients treated with cytotoxic agents alone. Pathological margin status was not significantly associated with 5-year OS in patients with a complete or near-complete response to chemotherapy and bevacizumab (43 versus 30 per cent after R0 versus R1 resection; P = 0·917), but this may be due to a type II error. CONCLUSION The impact of margin status varied according to the receipt of bevacizumab. Bevacizumab may have a role to play in improving outcomes among patients with more advanced disease.

Abstract
From an acetone-water (3:2) extract of aerial parts of Thymus gobicus Czern. (31.1 g), compounds 1-8 were obtained using high-performance liquid chromatography. Based on spectroscopic data, the isolated compounds were identified as rosmarinic acid (1), monardic acid A (2), nepetoidin B (3), aromadendrin (4), apigenin (5), chrysoriol (6), apigenin 7-O-β-D-glucuronopyranoside (7), and apigenin 7-O-β-D-glucuronopyranoside methyl ester (8). Compound 2 was a (7R,8R)-diastereomer of lithospermic acid (2a). Although it was reported that the anti-allergic activity of lithospermic acid was higher than that of 2, the acetylcholine inhibitory activity of 2 was higher than that of lithospermic acid.

Abstract
BACKGROUND AND AIM Minocycline therapy for acne vulgaris is associated with the occasional induction of various types of unsightly and often persistent hyperpigmentation, which is frequently resistant to hydroquinone treatment. Pigment-specific lasers have achieved some success with multiple treatment sessions. Recently, the picosecond domain 755 nm alexandrite laser (ps-Alex) has attracted attention in tattoo removal. The present study reports on the successful treatment, in a single ps-Alex session, of minocycline-associated pigmentation. SUBJECT AND METHOD Subsequent to a course of minocycline, a 28-year-old Asian female developed persistent type 2 minocycline-related pigmentation on the bilateral lower extremities which was recalcitrant to hydroquinone treatment. The patient had a test treatment on a small area with a Q-switched ruby laser and the ps-Alex, following which the ps-Alex was selected for the actual treatment (spot size, 2 mm; fluence, 6.37 J/cm2; pulsewidth, 750 ps) on one leg first, followed later by the contralateral leg. RESULTS Rapid clearance of the pigmentation was noted after a single ps-Alex session on both limbs without prolonged post-inflammatory hyperpigmentation (PIH). At one year post-treatment, clearance had been maintained. CONCLUSIONS Our results in this single case strongly suggest that the novel 755-nm ps-Alex laser is both safe and very effective for the treatment of type 2 minocycline-induced hyperpigmentation even in PIH-prone type IV Asian skin. Further trials with larger patient populations are warranted to confirm this optimistic result.

Abstract
OBJECTIVE Ameloblastoma (AM) shows locally invasive behaviour. However, biological investigations regarding regulation of gene expression associated with AM pathological features are difficult to perform, because AM cells can be passaged for a few generations due to senescence. We report a newly established immortalized AM cell line, AMB cells, by transfection with human telomerase reverse transcriptase (hTERT). Furthermore, we examined whether TNF-α modulates bone resorption-related genes, IL-6 and MMP-9 in cooperation with TGF-β or IFN-γ. MATERIALS AND METHODS Following transfection of an hTERT expression vector into AM cells using a non-viral method, the effects of cytokines on the expressions of IL-6 and MMP-9 mRNA were examined using real-time PCR. TNF-α-induced NF-κB activity was examined by western blotting and transcription factor assays. RESULTS AMB cells continued to grow for more than 100 population doublings. Stimulation with TNF-α increased IL-6 and MMP-9 mRNA expressions, as well as NF-κB activation. Furthermore, TGF-β and IFN-γ dramatically increased TNF-α-mediated expressions of MMP-9 and IL-6 mRNA, respectively, while those responses were suppressed by NF-κB inhibitor. CONCLUSION We established an immortalized AM cell line by hTERT transfection. TNF-α-mediated regulation of MMP-9 and IL-6 via NF-κB may play an important role in the pathological behaviour of AMs, such as bone resorption.

Abstract
LT for PFIC type 1 is often complicated by postoperative diarrhea and recurrent graft steatosis. A 26-month-old female child with cholestatic jaundice, pruritus, diarrhea, and growth retardation revealed total bilirubin 9.1 mg/dL, gamma-glutamyl transpeptidase 64 IU/L, and TBA 295.8 μmol/L. Genetic analysis confirmed ATP8B1 defects. A LT (segment 2, 3 graft) from the heterozygous father was performed. Biliary diversion was performed by a 35-cm jejunum conduit between the graft hepatic duct and the mid-transverse colon. Stools became pigmented immediately. Follow-up at 138 days revealed resolution of jaundice and pruritus and soft-to-hard stools (6-8 daily). Radioisotope hepato-biliary scintigraphy (days 26, 68, and 139) confirmed unobstructed bile drainage into the colon (t1/2 34, 27, and 19 minutes, respectively). Contrast meal follow-through at day 62 confirmed the absence of any colo-jejuno-hepatic reflux. At 140 days, contrast follow-through via the biliary stent revealed patent jejuno-colonic anastomosis and satisfactory transit. Graft biopsy at LT, 138 days, and 9 months follow-up revealed comparable grades of macrovesicular steatosis (<20%). TIBD during LT may be a clinically effective stoma-free biliary diversion and may prevent recurrent graft steatosis following LT for PFIC type 1.

Abstract
BACKGROUND Vonoprazan, a potassium-competitive acid blocker, is expected to improve the healing of endoscopic submucosal dissection (ESD)-induced gastric ulcers compared with proton pump inhibitors (PPIs). AIM To compare the healing status of ESD-induced gastric ulcers and the incidence of post-ESD bleeding between subjects treated with vonoprazan for 5 weeks and those treated with PPIs for 8 weeks. METHODS Patients in the vonoprazan group (n = 75) were prospectively enrolled, whereas patients in the PPI group (n = 150) were selected for a 2:1 matched historical control cohort according to baseline characteristics including gastric ulcer size immediately following ESD, age, sex and status of Helicobacter pylori infection. Two controls per case of vonoprazan-treated group were matched with a margin of 20% in terms of ulcer size and a margin of 5 years in terms of their age. RESULTS Although a higher number of completely healed ulcers was observed in the PPI group (95/150, 63.3%) than that in the vonoprazan group (14/75, 18.7%; P < 0.001), the ulcer size reduction rates, which were 96.0 ± 6.7% in the vonoprazan group and 94.7 ± 11.6% in the PPI group, were not significantly different (P = 0.373). The post-ESD bleeding incidence in the vonoprazan group (1/75, 1.3%) was less than that in the PPI group (15/150, 10.0%; P = 0.01). The factors affecting post-ESD bleeding incidence were the type of acid secretion inhibitor (P = 0.016) and use of an anti-thrombotic agent (P = 0.014). CONCLUSION Vonoprazan significantly reduced post-endoscopic submucosal dissection bleeding compared with PPIs.

Abstract
This paper describes novel methods of producing modified isocyanurate foams having low combustibility, high thermal stability and low smoke density. The research philosophy in this study is based on a hypothesis that by increasing the thermal stability of polymeric linkages, less flammable gases are generated which result in foams having lower combustibility, higher flame resistance, and higher thermal stability. The thermally-stable linkages employed in this study are amide-, imide-, and imide/carbodiimide linkages. Amide-modified isocyanurate foams were prepared by either a one step process or a two step process, using dimer acid, adipic acid or di-ketimine as modifier. The foams prepared by the two step process using adipic acid exhibited high closed cell content and therefore higher thermal insulation and high temperature stability. Imide-modified isocyanurate foams exhibited high flame-resistance and high closed cell content.

Abstract
The present case report describes a case of recurrent and advanced urachal carcinoma including neuroendocrine features with iliac bone metastasis after partial cystectomy and adjuvant chemotherapy consisting of irinotecan and cisplatin in a 32-year-old man. He received gemcitabine/cisplatin/ paclitaxel (GCP) combination chemotherapy, consisting of gemcitabin (1,000mg/m2) on day 1, 8, cisplatin (70mg/m2) on day 1, and paclitaxel (80mg/m2) on day 1 and 8. After three cycles of chemotherapy, PET-CT showed complete regression of the disease. So the patient underwent total cystourethrectomy, and histological examination showed an almost complete pathological response. External beam radiation therapy was also given to the ileac bone metastasis regions. However, PET-CT taken 17 months after the external beam radiation showed multiple lung metastases. He received GCP chemotherapy again, which resulted in a complete response again after three cycles of chemotherapy. This is the first report on GCP chemotherapy used not only as a salvage chemotherapy but also as a rechallenge regimen for metastatic urachal cancer including a neuroendocrine component.
