today, congenital heart diseases may be treated without surgery through advances in interventional cardiology. however, complications such as infection and thrombus formation may develop due to foreign materials used during these procedures. surgical intervention may be required for the removal of the device utilized for the procedure. in this case report, we present the surgical treatment of a...

Temporary intermittent complete heart block (CHB) occurred the day after interventional closure of an ASD with a 30 mm Gore Septal Occluder (GSO™) in a 2 years and 11-month-old female. CHB disappeared without further treatment and stable sinus rhythm recovered within 3 days. Only short episodes of 2nd degree AV-block (Wenckebach periodicity) at rare intervals were documented in Holter-monitors ...

shaped IUS’ Reading Dr Lloyd’s letter in the July 2013 issue of the Journal has prompted me to write in on this topic. Removal of an intrauterine device (IUD) involves traction on the threads causing the horizontal arms of the device to come together in the narrower lower half of the uterus during its downward movement. It is relatively easy for the collar of hormone in an intrauterine system (...

background: t ranscatheter closure of patent ductus arteriosus (pda) has become an alternative treatment to surgery. we evaluated the long-term results of the transcatheter closure of pda with the amplatzer duct occluder (ado) in children. methods: between may 2004 and october 2012, 138 children with pda (43 males and 95 females) underwent transcatheter pda closure. clinical, electrocardiograph...

Multiwall carbon nanotubes (MWCNTs) are grown via chemical vapour deposition method directly on a stainless steel substrate. Raman spectroscopy and transmission electron microscopy are the techniques chosen to characterize the structure of the synthesized carbon nanotubes: few structural defects are detected. After their removal from the stainless steel substrate, the as-grown MWCNTs are then a...

It has been suggested that laser fluorescence close to the dental pulp shows higher values than more distant measurements. The aim of this study was to assess fluorescence on the cavity floor and to correlate these measurements with electrical resistance as a measure of residual dentine thickness. Thirty carious lesions were excavated with a bur. The endpoint of caries removal was determined by...

The aim of this study was to assess costs and safety of immediate femoral sheath removal and closure with a suture-mediated closure device (Perclose, Menlo Park, CA) in patients undergoing elective (PCI). A total of 193 patients was prospectively randomized to immediate arterial sheath removal and access site closure with a suture-mediated closure device (SMC; n = 96) or sheath removal 4 hr aft...

BACKGROUND The insertion of a levonorgestrel-releasing intrauterine system (LNG-IUS) requires experience and is associated with a low failure rate. OBJECTIVES To assess the reasons given by gynecologists why they failed to insert a LNG-IUS. METHODS We obtained data from the sole distributor in Israel that prospectively recorded these cases when contacted by gynecologists following an insert...

Background: As a human carcinogen, formaldehyde is a toxic chemical imposing adverse effects on public health and environment. Due to its high reactivity, colorless nature, sustainability, purity in commercial forms, and low prices, the production and consumption of this compound has expanded vastly in industries. Methods: In this study, a UVC photoreactor with a total volume of 120 mL was us...
