Usefulness of lateral-anteroposterior dimeter ratio in patients with tracheomalacia associated with esophageal atresia.

Purpose: Tracheomalacia (TM) is commonly associated with esophageal atresia (EA) and compression by the brachiocephalic artery is a factor for TM. Previous research has focused on the lateral-to-anteroposterior tracheal diameter ratio (LAR). This study aimed to assess the LAR and postoperative outcomes of EA patients.

Lambda light chain - restricted non - crystalline proximal tubulopathy with cast nephropathy in multiple myeloma: a case report and literature review.

Background: Multiple myeloma (MM) often causes renal tubular damage, such as the light chain cast nephropathy (LCCN) and the light chain proximal tubulopathy (LCPT). The excessive light chains deposited in the proximal and distal tubules usually manifest with different characteristics, leading to a rare coexistence of the two pathological conditions. Here we report a unique case of a patient with multiple myeloma (MM) who presented with acute kidney injury (AKI) due to dual conditions of λ light chain-restricted non-crystalline LCPT and LCCN.

Developing an Effective Off-the-job Training Model and an Automated Evaluation System for Thoracoscopic Esophageal Atresia Surgery.

Background: Pediatric minimally invasive surgery requires advanced technical skills. Off-the-job training (OJT), especially when using disease-specific models, is an effective method of acquiring surgical skills. To achieve effective OJT, it is necessary to provide objective and appropriate skill assessment feedback to trainees.

Safe thoracoscopic repair of recurrent congenital diaphragmatic hernia after initial open abdominal repair.

Purpose: The optimal surgical approach for recurrent congenital diaphragmatic hernia (CDH) remains controversial. We compared the surgical outcomes of a thoracoscopic approach versus an open abdominal approach for recurrent CDH after initial abdominal open repair.

Method: The subjects of this comparative study were patients who underwent open abdominal or thoracoscopic surgery for recurrent CDH following an initial open abdominal repair.

Results: We included 6 RAS and 12 LS cases in this study.

Anastomotic time was associated with postoperative complications: a cumulative sum analysis of thoracoscopic repair of tracheoesophageal fistula in a single surgeon's experience.

Purpose: This study aimed to evaluate the learning curve of thoracoscopic repair of tracheoesophageal fistula (TEF) by a single surgeon using a cumulative sum (CUSUM) analysis.

Methods: Prospective clinical data of consecutive Gross type-C TEF repairs performed by a pediatric surgeon from 2010 to 2020 were recorded. CUSUM charts for anastomosis and operating times were generated.

Update on aortopexy and posterior tracheopexy for tracheomalacia in patients with esophageal atresia.

Despite improving the survival after repair of esophageal atresia (EA), the morbidity of EA repair remains high. Specifically, tracheomalacia (TM) is one of the most frequent complications of EA repair. Continuous positive airway pressure is generally applied for the treatment of TM.

Management of Congenital and Postoperative Chylothorax: Use of Thoracoscopic Lymphatic Leak Ligations with Intraoperative ICG Lymphangiography.

Background: Congenital chylothorax (CCT) and postoperative chylothorax (POCT) are rare and difficult to treat. We report our treatment strategy and outcomes for chylothorax, including thoracoscopic surgery with indocyanine-green (ICG) near-infrared fluorescence lymphangiography.

Methods: A retrospective review of patients with CCT and POCT from 2014 to 2021 was performed.

Case report: A giant bilateral inguinal hernia requiring artificial mesh and multi-stage surgery in infancy; hernioplasty with silo placement to prevent acute compartment syndrome.

Hernioplasty for giant inguinal hernias can cause abdominal compartment syndrome (ACS) in adults but rarely does in infants. We encountered a case of a giant bilateral inguinal hernia in infancy complicated by ACS after hernioplasty. Silo placement a skin incision effectively treated ACS, after which the abdominal wall was safely closed.

Rare case of a right Bochdalek hernia with retroperitoneal prolapse of organs into the thoracic cavity in infancy: A case report.

We report an extremely rare case of a right Bochdalek hernia with a sac, in which the retroperitoneal and intra-abdominal organs prolapsed into the thoracic cavity at the same time. The patient was a 7-month-old female with no comorbidities. She presented with cough and fever, and chest radiography revealed a right diaphragmatic hernia.

Laparoscopic internal intestinal drainage of bile lakes in a patient with recurrence of jaundice after laparoscopic revision of Kasai portoenterostomy for biliary atresia: A case report.

Bile lake, of the postoperative complications after Kasai portoenterostomy (PE) for biliary atresia, causes cholangitis that may induce progressive fibrosis of the liver. Standard treatment for bile lakes has not yet been established, but there are reports that surgical internal intestinal drainage for bile lakes effectively prevents cholangitis and maintains jaundice-free status. In this case, insertion of the percutaneous transhepatic biliary drainage into the bile lake allowed continuous drainage of large volumes of bile juice.

Biochemical markers to predict the development of gastrointestinal bleeding and esophageal varices after portoenterostomy in biliary atresia.

Purpose: Gastrointestinal bleeding (GIB) due to esophageal varices (EV) is one of the factors that negatively impact native liver survival of patients with biliary atresia (BA). Gastrointestinal fibroscopy (GIF) is usually used to determine the presence of EVs; however, it requires general anesthesia. The aim of this study is to search for markers in blood tests obtained during routine check-ups that can predict the development of GIB.

Laparoscopic bile duct plasty for hilar bile duct stenosis (HBDS) in patients with congenital biliary dilatation: Diagnosis of HBDS by preoperative MRCP and laparoscopic strategy to relieve HBDS.

Background/purpose: Congenital biliary dilatation (CBD) is a disease associated with pancreaticobiliary maljunction. The most frequent postoperative complication is intrahepatic stones, which are caused by hilar bile duct stenosis (HBDS).

Methods: We retrospectively reviewed the records of patients who underwent primary surgery for CBD between 2013 and 2021.

Band alignments and heterostructures of monolayer transition metal trichalcogenides MX (M = Zr, Hf; X = S, Se) and dichalcogenides MX (M = Tc, Re; X=S, Se) for solar applications.

Knowledge of band alignments and heterostructure formations is fundamental for a new generation of optoelectronics based on two-dimensional layered materials. Herein, band alignments and heterostructures of IVB-VIA monolayer MX (M = Zr, Hf; X = S, Se) and VIIB-VIA monolayer MX (M = Tc, Re; X = S, Se) are calculated by density functional theory with hybrid functionals. The results indicate that for monolayer MX, the valence bands mainly depend on the p state of the chalcogens and the conduction bands mainly depend on the d state of the transition metals.

Efficient mixed-solvent exfoliation of few-quintuple layer BiS and its photoelectric response.

A scalable liquid exfoliation of layered BiS employing a mixed-solvent strategy was used for the fabrication of BiS nanosheets. We found that 10% deionized water in 90% isopropyl alcohol is the best mixed solvent for the efficient and effective exfoliation of layered BiS. These results are consistent with the absorbance spectra and enthalpy of mixing theory.

Resonance Rayleigh scattering methods for the determination of chitosan with Congo red as probe.

Two methods were presented for the sensitive and selective determination of chitosan (CTS) with Congo red (CR) as probe based on resonance Rayleigh scattering (RRS) intensities in health products. In weakly acidic buffer solution, the binding of CTS to CR, could result in the enhancement of the RRS intensities. Moreover, after adding OP emulsifier (octyl-phenyl polyoxyethylene ether) to the system, the RRS intensities showed more significantly enhancement.

Surface Optical Rectification from Layered MoS Crystal by THz Time-Domain Surface Emission Spectroscopy.

Surface optical rectification was observed from the layered semiconductor molybdenum disulfide (MoS) crystal via terahertz (THz) time-domain surface emission spectroscopy under linearly polarized femtosecond laser excitation. The radiated THz amplitude of MoS has a linear dependence on ever-increasing pump fluence and thus quadratic with the pump electric field, which discriminates from the surface Dember field induced THz radiation in InAs and the transient photocurrent-induced THz generation in graphite. Theoretical analysis based on space symmetry of MoS crystal suggests that the underlying mechanism of THz radiation is surface optical rectification under the reflection configuration.

Solution-processable exfoliation and photoelectric properties of two-dimensional layered MoS photoelectrodes.

MoS based photoelectrodes with different thickness have been fabricated by liquid phase exfoliation and vacuum filtration method. Absorption spectra clearly demonstrated two splitting absorption peaks due to the spin-orbit coupling and first principle calculation also indicate the spin-orbit coupling effect. These results combined with the SEM and TEM measurement suggests that the randomly stacked MoS films can maintain the properties of few-layered materials with good quality.
