Michael Brückner
A 2-year-old Bearded Collie was referred for suspected hemoabdomen after prescrotal castration. On presentation the dog was in stable body condition and the hematocrit was within the reference range. Abdominal ultrasound revealed a moderate amount of free corpuscular fluid; therefore the dog was prepared for laparoscopic surgery. A single port access at the umbilicus was performed and insufflation with CO2 started with a pressure of 8 mmHg. Approximately one liter of blood was removed from the abdominal cavity with a suction/irrigation tube to allow inspection of the inguinal rings...

Microneedle patches, arrays of micron-scale projections that penetrate skin in a minimally invasive manner, are a promising tool for transdermally delivering therapeutic proteins. However, current microneedle fabrication techniques are limited in their ability to fabricate microneedles rapidly and with a high degree of control over microneedle design parameters. We have previously demonstrated the ability to fabricate microneedle patches with a range of compositions and geometries using the novel additive manufacturing technique Continuous Liquid Interface Production (CLIP)...

Colorectal cancers result in substantial morbidity and mortality to Australian society each year. The usual investigation for bowel malignancyis optical colonoscopy (OC), withcomputed tomographic colonography (CTC) used as an alternative investigation. The catharsis and colon insufflation associated with these investigations pose a higher risk in the elderly and frail. Risks include perforation, serum electrolyte disturbance, and anaesthesia/sedation risks.Minimal preparation computed tomographic colonography (MPCTC) eliminates these risks...

According to the Fifth German Oral Health Study, the caries experience in the German population is declining sharply. The number of teeth still present at an advanced age has also increased significantly in recent decades. This shows a clear trend towards long-term tooth preservation - possibly with fixed dental prostheses - which is further supported by the possibility to place implants to increase the number of abutments. The pronounced decline in caries experience has given Germany a leading international position in terms of dental health...

The use of dried blood spots (DBS) for antidoping purposes would facilitate an increase in the number of blood samples because it eliminates the need of specialized personnel and involves minimal invasiveness, reduced costs, stability and easy transportation and storage. Here, the electrophoretic methodology established by the World Anti-Doping Agency (WADA) to detect Erythropoiesis Stimulating Agents (ESAs) has been adapted to evaluate their applicability to DBS. A qualitative procedure to detect recombinant erythropoietin (rEPO), novel erythropoiesis stimulating protein (NESP) and continuous erythropoietin receptor activator (CERA) in one single DBS was optimized and validated...

BACKGROUND: Periacetabular osteotomy (PAO) is the treatment of choice for younger patients with developmental hip dysplasia. The procedure aims to normalize the joint configuration, reduce the peak-pressure, and delay the development of osteoarthritis. The procedure is technically demanding and no previous study has validated the use of computer navigation with a minimally invasive transsartorial approach. METHODS: Computer-assisted PAO was performed on ten patients...

Exploring the long-term filler for minimally invasive plastic surgery has been widely concerned. In the present study, a series of injectable paste composed of hydroxyapatite (HAp) spherical particles and cross-linked sodium hyaluronate (cHA) solution were prepared. The physicochemical properties of cHA as a carrier of high content HAp microspheres (>50%) and as-obtained injectable HAp/cHA paste were studied. The cross-linking degree (DC), viscosity and molecular weight (Mw and Mn) of cHA increased with the increasing of the cross-linker dosage from 7...

Describing and quantifying how much carious tissue should be removed prior to placing a restoration has been a long-debated issue stretching back as far as G.V. Black's "complete caries removal," now known as non-selective carious tissue removal. Originating in the 1960s and 1970s, from the differentiation between different layers of carious dentine, an outer contaminated ("infected") layer and an inner demineralised ("affected") layer, the former of which needed to be removed during cavity preparation and the latter not, selective carious tissue removal was born...

There have been many innovations in the field of ACL-reconstruction over the years, including the FlipCutter® and TightRope® system (both from Arthrex Inc.). The FlipCutter® is a combined guide pin and reamer that allows minimally invasive socket-creation from the inside out, especially in difficult-to-reach areas. The TightRope® is a further development of the well-known Endobutton™ (Smith & Nephew plc) that consists of a four-point knotless locking system. Its main advantage is its adjustability, which makes it possible to fill the entire bone socket with the graft without any empty space...

Proximal interphalangeal (PIP) joint arthritis causes debilitating hand pain and instability leading to significant functional impairment. Arthrodesis remains the gold standard for treatment of PIP arthritis. We present a minimally invasive PIP arthrodesis that provides rigid fixation with a headless compression screw. Seven patients who presented to the senior author with PIP joint arthritis underwent PIP arthrodesis by minimally invasive technique. A 1 cm transverse incision is made over the PIP joint, incising skin, central band, and articular capsule...

Superoxide overproduction is known to occur in multiple disease states requiring critical care yet non-invasive detection of superoxide in deep tissue remains a challenge. Herein, we report a metal-free magnetic resonance imaging (MRI) and electron paramagnetic resonance (EPR) active contrast agent prepared by "click conjugating" paramagnetic organic radical contrast agents (ORCAs) to the surface of tobacco mosaic virus (TMV). While ORCAs are known to be reduced in vivo to an MRI/EPR silent state, their oxidation is facilitated specifically by reactive oxygen species-in particular superoxide-and are largely unaffected by peroxides and molecular oxygen...

After pulp therapy or with multi-surface caries in primary molars, pre-formed stainless steel crowns are usually placed to ensure tooth longevity. Esthetic alternatives, such as zirconia crowns, have been proposed, but they are invasive. Here we describe two cases of chairside computer-aided design and computer-aided manufacturing (CAD/CAM) technology used to treat extended and/or deep caries on primary molars. A powder-free chairside CAD/CAM system, a milling unit and machinable high-performance composite blocks were used...

Injectable in situ forming hydrogels has great potential in tissue engineering. Simple and easy preparation of these hydrogels with low toxicity and stability is a great advantage. In the present study, two types of self-crosslinking in situ forming alginate based hydrogels with different formulation were synthesized, characterized and compared in order to introduce an optimal injectable scaffold in minimally invasive applications in tissue engineering. To this end, the hydrogels consist of oxidized alginate (AD), polyethylene glycol (PEG) and carboxymethyl chitosan (CMC) or gelatin (GEL) was synthesized...

Conventionally inseminated spermatozoa suffer a dramatic reduction in numbers during their long journey until fertilization. In addition sperm survival seems to be strongly affected by the reconstitution of the female reproductive tract in the post partum period. The purpose of this study was to develop a novel AI technique for cattle that allows the deposition of spermatozoa directly into the ampulla in the immediate vicinity of the fertilization site. This new reproductive biotechnique was investigated with focus on semen origin, sperm dosage, semen preparation and time of insemination...

Locoregional recurrence of breast cancer after tumor resection represents several clinical challenges. Here, we demonstrate that co-delivery of chemotherapy and thermotherapeutic agents by a magnetic supramolecular hydrogel (MSH) following tumor resection prevents tumor recurrence in a breast cancer mouse model. The self-assembled MSH was designed through the partial inclusion complexation associated with the threading of α-CD on the copolymer moieties on the surface of the PEGylated iron oxide (Fe3 O4 ) nanoparticles, which enables shear-thinning injection and controllable thermoreversible gel-sol transition...
