The curability of chemotherapy-resistant hepatoblastoma (HB) largely depends on the achievement radical surgical resection. Navigation techniques utilizing indocyanine green (ICG) are a powerful tool for detecting small metastatic lesions. We herein report patient who underwent second living donor liver transplantation (LDLTx) multiple recurrent HBs in graft following metastasectomy peritoneal dissemination with ICG navigation. initially presented ruptured HB at 6 years age and 3 resections...
Magnetoplasmonic nanostructures with enhanced magneto-optical (MO) activity hold great promise for the active manipulation of plasmon propagation. In this Rapid Communication, we demonstrate that shape elliptical nanocylinder plays an essential role on large MO activity: (1) saturated component depends angle polarization plane incident light respect to semimajor axis and (2) a low magnetic field induces nonferromagnetic origin exhibiting giant linear added in loops. The intriguing optical...
We have investigated the structure of liquid GaSb up to 20 GPa by a high-pressure and high-temperature x-ray-diffraction technique. With increasing pressure, hump at high-$Q$ side first peak in factor, $S(Q),$ reflecting an anisotropic local becomes smaller ratio wave number second that one, ${Q}_{2}{/Q}_{1},$ decreases. Simultaneously, coordination CN increases correspondence elongation nearest-neighbor distance compared expected from uniform contraction model. These findings suggest...
We performed the first autologous oral mucosa-derived epithelial cell sheet transplantation therapy in a patient with refractory postoperative anastomotic stricture congenital esophageal atresia (CEA) and confirmed its safety. In this study, patients CEA stenosis were newly added as subjects to further evaluate safety efficacy of therapy.Epithelial sheets prepared from mucosa transplanted into tears created by endoscopic balloon dilatation (EBD). The was quality control testing, treatment...
We investigate the structure of liquid InSb over a wide pressure range up to 20 GPa and temperature 1570 K by synchrotron x-ray diffraction. With increasing along melting curve, local structure, which is anisotropic near ambient pressure, becomes more isotropic. However, at pressures higher than about 10 GPa, pressure-induced change less prominent, contracts almost uniformly. Structural parameters deviate significantly from those in simple metals this region, revealing stable form with an...
No standard diagnostic method or surgical treatment for congenital isolated hypoganglionosis (CIHG) has been established.

Data on in 19 were collected between 1992 2020, including type enterostomy, revision, length intestines. Ganglion cells myenteric plexus enumerated using Hu C/D staining. The ratio small intestine its height was defined as intestinal (IR). assessed...
The principle of hepatoblastoma (HB) treatment is complete resection. removal tumor-bearing section(s) or hemiliver widely accepted. However, neither the standardized anterior approach for right hepatectomy nor parenchymal sparing anatomical liver resection has been described HB.We retrospectively reviewed clinical course two pediatric HB patients who underwent extended using with hanging maneuver and one S4 apical+S8 ventral/dorsal+S7. critical aspects surgical techniques are in detail.In...
Abstract Background Pleuroperitoneal communication (PPC) is an uncommon, but potentially life-threatening complication of peritoneal dialysis (PD). If a fistula does not close with conservative treatment, surgical repair required. However, approximately half these patients are forced to shift from PD hemodialysis. Although it important confirm the site achieve successful this identification more difficult in pediatric than adults. Case presentation We report two infantile cases severe PPC...
Extrahepatic congenital portosystemic shunts (CPSSs) can be occluded by surgical or endovascular approaches. However, when the estimated portal vein (PV) pressure after closure is high enough to induce symptoms associated with hypertension, partial recommended avoid life-threatening events. In this study, we attempted laparoscopic of a CPSS in two patients. Along intraoperative real-time measuring PV and angiography, was performed achieve ≤25 mmHg. Subsequently, intrahepatic system grew both...
We have fabricated two kinds of silicon microoptical mirrors to make optical axes high-power laser diodes close at an interval 100 /spl mu/m, utilizing anisotropic etching with the self-alignment mask. One them is a microrectangular prism mirror (MRPM). It has orthogonal reflection mirrors, composed polished [110] and anisotropically etched (111) planes silicon. The other micro two-reflection (MTRM). pairs reflectors facing each in parallel. use MTRM made mounting process easier than that...
Yolk sac tumor (YST) is a germ cell that generally associated with good prognosis in children. It has been recently reported vaginal YSTs can be cured using chemotherapy alone. Thus, minimal invasiveness and function preservation are pre-requisites for surgical approaches. Herein, we report case of YST was resected function-preserving manner unique combination In 9-month-old Asian female infant, detected while investigating bleeding. The patient referred to our hospital, the diagnosed as...
Background Umbilical mucosal polyps are common, but physicians' unfamiliarity with them can prolong the patient's illness. Furthermore, details of surgery for umbilical polyp removal not well documented. Methods Patients an diagnosed on basis lesion's characteristic appearance were prospectively enrolled. The involved scarectomy a minimum surrounding skin and exploratory laparotomy to detect any lesions extending into peritoneal cavity. Results Fourteen patients median duration illness ten...
Groove pancreatitis is a type of where inflammation occurs in the "groove area" which narrow space surrounded by duodenum, head pancreas and common bile duct, lymph nodes, blood vessels pancreatic duct exist. area causes duodenal stenosis/obstruction, narrowing extrahepatic biliary tree sometimes pancreatitis. The exact etiology disease not well understood but Santorini obstruction (congenital or acquired) may be associated with groove area, partly caused excessive alcoholic intake...
