Experimental Substantiation

The results of the anatomic and angiographic study of the radial and anterior serratus muscle fascial grafts on 30 cadavers are presented. Basing on the results of the work it is possible to conclude that potential introduction of this plastic material into clinical practice for the extremity reconstruction is desired, ft is the first time that the technique of the radial fascial graft harvesting is described in details. Angiographic results showed good blood supply of the isolated fascial grafts.

Extremity Reconstruction

Vascularised epiphysial fibula bone transfers in the paediatric population provides a solution to growth suppression in extremity reconstruction. We report a case of an anatomical variant to the epiphysial blood supply that has never been reported in literature. A 6-year-old girl underwent a free vascularised fibula flap for reconstruction of her right humerous following osteosarcoma resection. While identifying and dissecting the recurrent epiphysial branch, a large branch from the peroneal artery was identified which directly entered the head of the fibula. No dominant supply from the anterior tibial (AT) vessels to the head of the fibula was seen. This led to the need for a bipedicled flap with diaphyseal supply from the AT vessels and the epiphysial transfer based on the peroneal artery. The patient made an uneventful recovery from the procedure. The same technique may be used by surgeons that may encounter this unique variant in clinical practice.

Positively Charged

The process of releasing liquid carbon dioxide from a fire extinguisher is accompanied by a strong static charging of the plastic material making up the extinguisher discharge horn. Firefighters often report an electric shock when operating CO2 extinguishers, but the origin of this electrostatic hazard is largely unknown. Here, we begin to investigate this phenomenon, and test the hypothesis of plastic samples being tribocharged on contact with rapidly flowing solid CO2. Using Faraday pail measurements, we show that non-conductive polymers gain a net static charge when brought in and out of contact with dry ice (solid CO2). These measurements of charge sign and magnitude give indirect evidence helping to place solid CO2 for the first time on the triboelectric series. Polydimethylsiloxane (PDMS), polytetrafluoroethylene (PTFE), and polyvinyl chloride (PVC) samples acquire a negative charge when rubbed against dry ice, whereas poly(methyl methacrylate) (PMMA), glass, and nylon surfaces become positively charged. Therefore, we suggest the position of dry ice in the triboelectric series to be close to that of materials with stable cations and unstable anions, possibly locating it between PMMA and PVC.

SUMMARYThere is much Mental Capacity Act 2005 (MCA) case law emanating from the Court of Protection. This article reviews an important and unique case when the court specifically addressed for the first time the question of fluctuating capacity, a not uncommon clinical problem that can often be complex. It describes how the Court of Protection in Royal Borough of Greenwich v CDM [2019] legally approached an issue of fluctuating capacity in a 64-year-old woman with a personality disorder and chronic diabetes. In doing so it elucidates a new conceptual framework to apply when assessing fluctuating capacity in terms of considering micro- and macro-decisions which can be used in routine clinical practice.

The present work is an anatomical demonstration of the collateral blood supply which maintains the liver after acute interruption of the hepatic artery. This is demonstrated with x-ray films and corrosion specimens of the livers of dogs weeks to months following excision of the hepatic artery. The livers were injected with red lead suspension or with a plastic material. With both methods, we have demonstrated the development of adequate anastomoses within the liver between the phrenic and the hepatic arteries. The phrenic arteries had hypertrophied considerably and numerous good sized anastomoses with the hepatic arteries were present, allowing for an adequate supply of arterial blood to the liver and survival of the animal. In similar control experiments on normal dogs, the phrenic arteries were small, and insignificant anastomoses to the hepatic arteries were found.

AbstractThis communication presents precise percentile values for birth weight, birth length and cranial circumference of infants in Mecklenburg-Pomerania, Germany.Based on data from the German Perinatal Survey of the years 1994–2011 in Mecklenburg-Pomerania, the 3rd, 10th, 25th, 50th, 75th, 90th and 97th percentile values for birth weight, birth length and head circumference are specified. The measurements of a total of 174 084 infants from non-multiple births are shown.The statistically calculated percentile values are presented in tabular and graph forms. The mean birth weight of the infants was 3 437.8 g. The average age of the mothers was 27.9 years. The average duration of pregnancy was 39.4 complete weeks.The insights gained from many years of data collection are presented as standardised, regional percentile values and curves for Mecklenburg-Pomerania for the first time. The differentiated presentation for the federal state opens the possibility for individually tailored consultations in clinical practice and may provide support for recognised national curves for these values.

The article presents the results of anatomical studies aimed to develop modelling of facial allografts taking into account the peculiarities of blood supply. The allografts should meet both aesthetic and functional needs of the recipient for further use in clinical practice. There were selected 3 facial composite tissue allografts out of 50 modifications, which are more suitable for required parameters. On basis of these data, there was successfully performed the facial composite tissue allograft transplantation on the patient.
