INTRODUCTION: Surgical resection is usually performed for the treatment of endobronchial tumors. This case describes the use of endoscopic resection as an initial treatment, allowing to spare lung parenchyma. CASE REPORT: A patient was admitted to the emergency unit with right lower lobe pneumonia. A thoracic CT-scan and subsequent bronchoscopy revealed an intrabronchial tumor between the right main and intermediate bronchus. Biopsies were non-diagnostic and a PET-scanner did not find any abnormalities...

A best evidence topic was written according to a structured protocol. The question addressed was: in surgically fit patients with biopsy proven symptomatic endobronchial hamartoma (EH), is surgical resection superior to bronchoscopic resection in terms of outcome. A total of 756 articles were identified using the reported search, of which 8 represented the best evidence to answer the clinical question. The authors, date, journal, country, study type, population, outcomes and key results are tabulated. Three studies included patients who had either bronchoscopic or surgical treatment of EH in the same study...

Topographical and chemical features of biomaterial surfaces affect the cell physiology at the interface and are promising tools for the improvement of implants. The dominance of the surface topography on cell behavior is often accentuated. Striated surfaces induce an alignment of cells and their intracellular adhesion-mediated components. Recently, it could be demonstrated that a chemical modification via plasma polymerized allylamine was not only able to boost osteoblast cell adhesion and spreading but also override the cell alignment on stochastically machined titanium...

Bio-recalcitrant micropollutants are often insufficiently removed by modern wastewater treatment plants to meet the future demands worldwide. Therefore, several advanced oxidation techniques, including cold plasma technology, are being investigated as effective complementary water treatment methods. In order to permit industrial implementation, energy demand of these techniques needs to be minimized. To this end, we have developed an electrical discharge reactor where water treatment by dielectric barrier discharge (DBD) is combined with adsorption on activated carbon textile and additional ozonation...

Weight regain after bariatric surgery is common and can be managed with surgical interventions or less morbid endoscopic techniques. These endoscopic approaches target structural postoperative changes that are associated with weight regain, most notably dilation of the gastrojejunal anastomosis aperture. Purse string suture placement, as well as argon plasma coagulation application to the anastomosis, may result in significant and durable weight loss. Furthermore, various endoscopic approaches may be used to safely and effectively manage other complications of bariatric surgery that may result in poor weight loss or weight regain after surgery, including fistula formation...

BACKGROUNDS AND AIM: No well-established treatment strategies exist for lateral margin positivity (LM+) alone after endoscopic resection (ER) of early gastric cancer (EGC). Thus, we aimed to clarify treatment strategy of non-curative resection (non-CR) with LM + alone after ER in EGC. METHODS: Among 2,065 patients with EGC treated by ER, 76 (3.6%) exhibiting only LM+ after non-CR of EGC were reviewed retrospectively. Of these, 28 underwent gastrectomy, 25 argon plasma coagulation (APC), and 23 re-ER...

INTRODUCTION: Proton pump inhibitor (PPI) use is associated with the development of fundic gland polyps (FGPs); discontinuing PPIs is associated with regression of FGPs. Here, we report a rare case of non-respondent FGPs after discontinuation of PPI that were successfully treated using an argon plasma coagulator (APC). PRESENTATION OF CASE: We present the case of a 68-year-old woman with a history of polycytheamia vera. She also had gastroesophageal reflux disease (GERD) and had been taking 10 mg of omeprazole daily for the past three years...

A 28-year-old Caucasian man was admitted in our unit for acute massive rectal bleeding. Past medical and family history was unremarkable. Hemoglobin was 7.6 g/dL. Blood transfusions were required. Computed tomography and gastrointestinal endoscopy were negative for active bleeding. When patient's hemoglobin was normalized and stable, a video capsule endoscopy was performed. Video relieved the presence of multiple digiunal and ileal angiodysplastic lesions. A double endoscopic argon plasma coagulation procedure was planned on general anaesthesia...

Vanadium has a unique and beneficial effect on both humans and animal organisms; however, excessive amount of the above-mentioned metal can cause many alterations in tissues and organs, including the kidneys. The aim of the study was to determine the concentration of vanadium (V) in the kidneys removed from patients due to lesions of various etiologies, including the rejection of the transplanted kidneys. Additionally, we determined the influence of selected biological and environmental factors on the V concentration...

This paper deals with the development and construction of an apparatus for time-resolved tunable diode laser absorption spectroscopy (LAS) for the diagnostics of pulsed plasma. A detailed description of the extension of a progressive method of laser absorption spectroscopy in continuous regime to a direct triggering method of the time-resolved laser absorption spectroscopy (TR-LAS) is presented. The main advantage of the developed method is its capability to measure the time evolution of the whole absorption profile with a preset time resolution, which can be less than 1 μs...

This paper presents the use of thermocouples and line broadening of argon 2p-1s emission lines for the measurement of gas temperature of an atmospheric argon microplasma jet. The measured temperatures are compared with rotational spectra fitting of OH (A-X) and N2 (C-B) emission. An rf microplasma jet with two electrical configurations and different temperature ranges was used. The calculated gas temperatures with thermocouples, argon lines, and OH ranged from 290 to 423 K and 393-510 K for the two configurations, depending on the rf power...

We present a model for quasi-phase matching (QPM) in high-order harmonic generation (HHG). Using a one-dimensional description, we analyze the time-dependent, ultrafast wave-vector balance to calculate the on-axis harmonic output versus time, from which we obtain the output pulse energy. Considering, as an example, periodically patterned argon gas, as may be provided with a grid in a cluster jet, we calculate the harmonic output during different time intervals within the drive laser pulse duration. We find that identifying a suitable single spatial period is not straightforward due to the complex and ultrafast plasma dynamics that underlies HHG at increased intensities...

Gastric antral vascular ectasia (GAVE) continues to be a challenge in both diagnosis and treatment. GAVE has a diverse group of associations and presumed causes, including cirrhosis, chronic renal failure and autoimmune connective tissue diseases. However, in most occasions, the management plan of GAVE itself is the same whatever the underlying disease by using Argon plasma coagulation (APC). Herein, we will discuss three cases of systemic sclerosis-associated GAVE presenting with either acute or chronic gastrointestinal bleeding showing variable responses to APC...
