Ernst Wertheim was a pioneer in the history of the surgical treatment of cervical cancer. His English-language manuscript "The extended abdominal operation for carcinoma uteri (based on 500 operative cases)," which was published in 1912, detailed his standardization of the radical hysterectomy and formed the basis of the current treatment for early stage cervical cancer. We contextualize the Wertheim hysterectomy, emphasizing medical advances that allowed for its development and subsequent modification. We then discuss modifications to the originally proposed procedure, including a maximally extended parametrical resection pioneered by Takayama, and the addition of the Taussig en bloc lymph node dissection by Meigs, both of which afforded an improved mortality profile due to decreased disease recurrence...

Butyrate, an intestinal microbiota metabolite of dietary fiber, exhibits chemoprevention effects on colon cancer development. However, the mechanistic action of butyrate remains to be determined. We hypothesize that butyrate inhibits cancerous cell proliferation but to a lesser extent in noncancerous cells through regulating apoptosis and cellular-signaling pathways. We tested this hypothesis by exposing cancerous HCT116 or non-cancerous NCM460 colon cells to physiologically relevant doses of butyrate. Cellular responses to butyrate were characterized by Western analysis, fluorescent microscopy, acetylation, and DNA fragmentation analyses...

Surgery for Tetralogy of Fallot progressed rapidly from the palliative arterio-pulmonary Blalock-Taussig shunt, introduced in Baltimore 70 years ago, to the "classic" complete transventricular repair technique, with which excellent early results were achieved soon thereafter. However, as duration of follow-up increased, so did the awareness of development of troubling late complications, including severe pulmonary insufficiency, right ventricular dilatation and dysfunction, and tricuspid valve insufficiency, all contributing to increasing incidence of late reoperations, as well as to arrhythmias and sudden death...

Charles D Fraser
The neonatal arterial switch operation has become the standard of care for transposition of the great arteries, including transposition with intact ventricular septum, transposition with ventricular septal defect with or without aortic arch hypoplasia, and double outlet right ventricle with subpulmonary ventricular septal defect (Taussig-Bing anomaly). While technically demanding, the operation is enormously gratifying and exciting for the congenital heart surgeon. In the current era, outcomes and expectations for the neonatal arterial switch operation are extremely high with many centers, including our own, reporting 30-day or hospital survivorship approaching 100%...

OBJECTIVES: The study objective was to determine the predictors of new-onset arrhythmia among infants with single-ventricle anomalies during the post-Norwood hospitalization and the association of those arrhythmias with postoperative outcomes (ventilator time and length of stay) and interstage mortality. METHODS: After excluding patients with preoperative arrhythmias, we used data from the Pediatric Heart Network Single Ventricle Reconstruction Trial to identify risk factors for tachyarrhythmias (atrial fibrillation, atrial flutter, supraventricular tachycardia, junctional ectopic tachycardia, and ventricular tachycardia) and atrioventricular block (second or third degree) among 544 eligible patients...

A design to extend the unique divertor Thomson scattering system on DIII-D to allow measurements of electron temperature and density in high triangularity plasmas is presented. Access to this region is selectable on a shot-by-shot basis by redirecting the laser beam of the existing divertor Thomson system inboard - beneath the lower floor using a moveable, high-damage threshold, in-vacuum mirror - and then redirecting again vertically. The currently measured divertor region remains available with this mirror retracted...

Motivated by the need to measure fast equilibrium temporal dynamics, non-axisymmetric structures, and core magnetic fluctuations (coherent and broadband), a three-chord Faraday-effect polarimeter-interferometer system with fast time response and high phase resolution has recently been installed on the DIII-D tokamak. A novel detection scheme utilizing two probe beams and two detectors for each chord results in reduced phase noise and increased time response [δb ∼ 1G with up to 3 MHz bandwidth]. First measurement results were obtained during the recent DIII-D experimental campaign...

Patients with hypoplastic left heart syndrome undergo a series of operations to separate the pulmonary and systemic circulations. The first of at least 3 operations occurs in the newborn period, with a stage I palliation. The goal of stage I palliation is to provide pulmonary blood flow and create an unobstructed systemic outflow tract. Advances in surgical techniques and intraoperative and postoperative care have helped decrease morbidity and mortality for patients with hypoplastic left heart syndrome who have the stage I Norwood operation, but the patients continue to be at increased risk for hemodynamic collapse and adverse outcomes...

BACKGROUND: The stage 1 Norwood procedure and its variants represent the first step of palliation for hypoplastic left heart syndrome. Although appropriate postoperative thromboprophylaxis is integral, significant variance remains across institutional practices. The purpose of this systematic review is to estimate the incidence of thrombosis and thromboembolism following the Norwood or modified Blalock-Taussig shunt procedure and examine current thromboprophylaxis regimens. METHODS: Ovid MEDLINE and Embase were searched from January 2000 to June 2016 for primary studies explicitly reporting incidence of thrombosis, thromboembolism (strokes and pulmonary embolisms), or shunt occlusion in neonates, infants, and children undergoing the Norwood procedure or any variant...

Optimal hemodynamics in aorta-pulmonary shunt reconstruction is essential for improved post-operative recovery of the newborn congenital heart disease patient. However, prior to in vivo execution, the prediction of post-operative hemodynamics is extremely challenging due to the interplay of multiple confounding physiological factors. It is hypothesized that the post-operative performance of the surgical shunt can be predicted through computational blood flow simulations that consider patient size, shunt configuration, cardiac output and the complex three-dimensional disease anatomy...

BACKGROUND: Systemic vasodilation using α-receptor blockade has been shown to decrease the incidence of postoperative cardiac arrest following stage 1 palliation (S1P), primarily when utilizing the modified Blalock-Taussig shunt. We studied the effects of a protocol in which milrinone was primarily used to lower systemic vascular resistance (SVR) following S1P using the right ventricular to pulmonary artery shunt, measuring its effects on oxygen delivery (DO2) profiles and clinical outcomes...

The paper presents the management of a child born with pulmonary valve atresia, a single (double-inlet) ventricle, right ventricular hypoplasia, and perimembranous septal defect. The first stage of treatment consisted in a Blalock-Taussig shunt. Control angiography performed 1 year after surgery confirmed that the anastomosis was correct, and there was no narrowing at the connection. The first stage of treatment was complicated by the occlusion of the left pulmonary artery, as diagnosed during cardiac catheterization before the planned bidirectional Glenn anastomosis...

Universally fatal only 4 decades ago, the progress in the 3-stage palliation of hypoplastic left heart syndrome and related single right ventricular lesions has drastically improved the outlook for these patients. Although the stage II operation (hemi-Fontan or bidirectional Glenn) and stage III Fontan procedure have evolved into relatively low-risk operations, the stage I Norwood procedure remains one of the highest-risk and costliest common operations performed in congenital heart surgery. Yet, despite this fact, experienced centers now report hospital survivals of >90% for the Norwood procedure...

We report a modified Norwood stage I procedure for tricuspid atresia, transposition of great arteries, and hypoplastic right aortic arch with complete vascular ring. In this technique, we applied dual arterial cannulation to avoid circulation arrest during neoaortic reconstruction, and also corrected the arch laterality during the Norwood stage I palliation procedure. Pulmonary flow was supplied by the Blalock-Taussig shunt. Postoperative imaging revealed the patent left neoaortic arch, and the vascular ring was relieved with a patent tracheobronchial tree...

Management of pulmonary atresia with ventricular septal defect (PA-VSD) in the neonatal period presents numerous challenges. Endovascular stenting of the ductus arteriosus or of a collateral vessel in ductal-dependent pulmonary circulation as an alternative to the Blalock-Taussig (BT) shunt has become increasingly popular in the last decades. The utilization of the reverse Szabo (anchor-wire) technique for single collateral vessel stenting in a case of PA-VSD is described.

A 30-year-old female with tricuspid valve atresia, ventricular septal defect, and atrial septal defect had a neonatal modified Blalock Taussig shunt and a Fontan-Björk operation performed at five years of age. She did well initially but progressively developed signs of systemic congestion due to severe homograft stenosis and underwent successful percutaneous implantation of a Melody(®) pulmonary valve (Medtronic, Minneapolis, MN, USA) in the "tricuspid" position.

In this study, we describe an infant case of pulmonary atresia with intact ventricular septum associated with ventriculo-coronary arterial communication for which a modified Blalock-Taussig shunt operation was performed. He experienced repeated myocardial ischaemic attacks. Further examination revealed pulmonary sequestration in the right lower lobe. He therefore underwent a bidirectional Glenn operation and coil occlusion of the feeding arteries. His myocardial ischaemic attacks subsequently improved.
