OBJECTIVES/HYPOTHESIS: A secure airway is critical to study obstructive disorders of the larynx and trachea in preclinical models. Tracheostomy has been described in rabbits, swine, canines, and other mammals using tracheostomy tubes or permanent stomas. No studies specifically evaluated morbidity and mortality associated with these models, and existing studies using tracheostomy make little mention of tracheostomy-related complications. We assessed the management, complications, and mortality associated with tracheostomy in a rabbit model that has recently gained significant attention...

AIM: This study described end-of-life care for children affected by spinal muscular atrophy type 1 (SMA1), which is characterised by progressive muscle weakness and develops in the first six months of life. METHODS: We retrospectively analysed 17 children (13 boys) who attended the University of Padua's paediatric palliative care centre in Italy from March 2000 to March 2015. All the children received supportive care without proactive respiratory intervention to prolong survival...

Rotary biventricular assist devices (BiVAD) are becoming a clinically accepted treatment option for end-stage biventricular failure. To improve BiVAD efficacy and safety, we propose a control algorithm to achieve the clinical objectives of maintaining left-right-sided balance, restoring physiologic flows, and preventing ventricular suction. The control algorithm consists of two proportional-integral (PI) controllers for left and right ventricular assist devices (LVAD and RVAD) to maintain differential pump pressure across LVAD (ΔPL) and RVAD (ΔPR) to provide left-right balance and physiologic flow...

OBJECTIVE: The postoperative systemic inflammatory response after cardiopulmonary bypass (CPB) is still an undesirable side-effect after cardiac surgery. It is most likely caused by blood contact with foreign surfaces and by the surgical trauma itself. However, the recirculation of activated shed mediastinal blood is another main cause of blood cell activation and cytokine release. Minimal invasive extracorporeal circulation (MiECC) comprises a completely closed circuit, coated surfaces and the separation of suction blood...

Bladderworts (Utricularia, Lentibulariaceae, Lamiales) constitute the largest genus of carnivorous plants but only aquatic species (about one fifth of the genus) have so far been thoroughly studied as to their suction trap functioning. In this study, we comparatively investigated trap biomechanics in 19 Utricularia species to examine correlations between life-forms, trapping mechanisms, and functional-morphological traits. Our investigations show the existence of two functional trap principles (passive trap in U...

Many tissues exhibit subatmospheric interstitial pressures under normal physiologic conditions. The mechanisms by which the lymphatic system extracts fluid from these tissues against the overall pressure gradient are unknown. We address this important physiologic issue by combining experimental measurements of contractile function and pressure generation with a previously validated mathematical model. We provide definitive evidence for the existence of 'suction pressure' in collecting lymphatic vessels, which manifests as a transient drop in pressure downstream of the inlet valve following contraction...

BACKGROUND: In case of keratoconus, rigid gas-permeable contact lenses as the correction method of first choice allow for a good visual acuity for quite some time. In a severe stage of the disease with major cone-shaped protrusion of the cornea, even specially designed keratoconus contact lenses are no more tolerated. In case of existing contraindications for intrastromal ring segments, corneal transplantation typically has a very good prognosis. METHODS: In case of advanced keratoconus - especially after corneal hydrops due to rupture of Descemet's membrane - penetrating keratoplasty (PKP) still is the surgical method of first choice...

Laryngeal cleft is a rare congenital malformation of the respiratory tract leading to a high level of morbidity and mortality, recently being diagnosed with increased frequency. Management throughout the years included medical and surgical. The open surgical technique is more commonly used although it has higher risk and need longer post-operative care. Recently surgical endoscopic repair was introduced using different techniques. To evaluate the clinical features of infants and children presenting with laryngeal clefts, and review endoscopic management modality especially the technique and results of repair using double-layer (2 layers) technique...

INTRODUCTION: Laparoscopic management of giant hydatid cyst has limitations such as spillage, poor control, difficulties in suctioning the contents through special ports which are not easily available, difficulty in the obliteration of residual cavity and recurrence. We describe single-incision trocar-less endoscopic (SITE) technique which simplifies enucleation and management of residual cavity. METHOD: Inclusion criteria for these cases were patients having single uncomplicated giant hydatid cyst >5 cm present at the surface of the liver and palpable on clinical examination...

Split-thickness skin grafting (STSG) is the current gold standard for treatment of extensive burn and traumatic skin injuries. However, STSG is limited by donor-site morbidity and availability, and often leads to scarring and wound contracture. Furthermore, these thin grafts lack dermal elements such as nerves and adnexa which are important in recapitulating normal skin function. Methods of fractional skin replacement either as minced STSGs or microscopic skin tissue columns (MSTCs) have been proposed, though these techniques have not been fully-characterized and lack evidence of regenerated adnexal structures...

BACKGROUND The 800 nm long-pulsed diode laser machine is safe and effective for permanent hair reduction. Traditionally, most long-pulsed diode lasers used for hair removal had a relatively small spot size. Recently, a long-pulsed diode laser with a large spot size and vacuum assisted suction handpiece was introduced. The treatment parameters of each type of handpiece differ. Short and long-term clinical efficacy, treatment associated pain, and patient satisfaction are important factors to be considered. OBJECTIVE: This study aims to conduct a direct head to head comparison of both handpieces of the 800nm long-pulsed diode laser by evaluating long term hair reduction, treatment associated pain and patient satisfaction...

A 59-year-old man developed massive hemoptysis, 1 month after undergoing cryoablation procedure for atrial fibrillation. He underwent emergent bronchoscopy that revealed massive, active bleeding with clots requiring repeated suctioning, epinephrine, and cold saline injection. The source of bleeding was identified in a follow-up bronchoscopy performed few days later-a 2×3 cm area of ulceration of the left main stem bronchus which was missed in the initial bronchoscopy owing to blood obscuring the field of vision...

Systemic immune function is impaired by sleep restriction. However, the impact of sleep restriction on local immune responses, and to what extent any impairment can be mitigated by nutritional supplementation is unknown. We assessed the effect of 72-h sleep restriction (2-h nightly sleep) on local immune function and skin barrier restoration of an experimental wound, and determined the influence of habitual protein intake (1.5 g·kg(-1)·d(-1)) supplemented with arginine, glutamine, zinc sulfate, vitamin C, vitamin D3 and omega-3 fatty acids compared to lower protein intake (0...

Analysis of epidermal genes, proteins and lipids is important in the research and diagnosis of skin diseases. Although punch biopsy is the first-choice technique for the skin sampling, it is unnecessarily invasive for obtaining a sample just for the epidermal analysis. Here we compare two less invasive methods, suction blistering (SB) and tape stripping (TS), for the analysis of selected epidermal genes (quantitative real-time reverse transcription PCR, qRT-PCR), proteins (western blotting, WB), and lipids in ten healthy volunteers...

INTRODUCTION: Postoperative sore throat is listed from the top as patients' most undesirable outcome in the postoperative period. It is believed to originate from mucosal dehydration or edema, tracheal ischemia secondary to the pressure of endotracheal tube cuffs, aggressive oropharyngeal suctioning, and mucosal erosion from friction between delicate tissues and the endotracheal tube. Even if the problem was indicated in many literatures, it has never been studied in our country. The study aimed to assess prevalence and factors associated with postoperative sore throat among patients who were operated under general anesthesia with endotracheal intubation...

We used suction electrodes to reliably record the activity of identified ascending auditory interneurons from the anterior surface of the brain in crickets. Electrodes were gently attached to the sheath covering the projection area of the ascending interneurons and the ring-like auditory neuropil in the protocerebrum. The specificity and selectivity of the recordings were determined by the precise electrode location, which could easily be changed without causing damage to the tissue. Different non-auditory fibres were recorded at other spots of the brain surface; stable recordings lasted for several hours...

Various control and monitoring algorithms have been proposed to improve the left-ventricular assist device (LVAD) therapy by reducing the still-occurring adverse events. We developed a novel multi-objective physiological control system that relies on the pump inlet pressure (PIP). Signal-processing algorithms have been implemented to extract the required features from the PIP. These features then serve for meeting various objectives: pump flow adaptation to the perfusion requirements, aortic valve opening for a predefined time, augmentation of the aortic pulse pressure, and monitoring of the LV pre- and afterload conditions as well as the cardiac rhythm...
