The aim of the study was to evaluate the role of virtual bronchoscopy (VB) in traumatic rupture of the main bronchus Material and methods. Тhe data of virtual bronchoscopy of multispiral computed tomography (MSCT) with multiplanar and 3D reconstructions of 10 patients with traumatic separation of the main bronchus were analyzed. MSCT was carried out by the computer tomograph AquilionONE (320-slice) according to the previously described technique. Results of the study. VB MSCT allowed to determine the presence of a complete or partial rupture of the main bronchus, its distance to the bifurcation of the trachea, the state of the collapsed lung, the presence of fluid in the hemithorax, secondary changes in the bone structures of the chest. The World Bank played an important role in monitoring the adequacy of reconstructive measures on the damaged bronchus, excluding the occurrence of postoperative stenosis. The conclusion. Virtual bronchoscopy of multispiral computed tomography with the capabilities of multiplanar and volumetric reconstructions, postprocessing image processing is an optimal non-invasive method for determining the traumatic lesion of the main bronchi and monitoring the success of the reconstructive surgical manual.

Six adult loggerhead turtles were found stranded and were rescued near Sicily within a period of 12 months. Macroscopically apparent lesions of the shell were present. After thorough physical examination, ketamine-dexmedetomidine-atipamezole induction and tracheal tube insertion all six patients underwent computed tomographic examination under inhalant anaesthesia with isoflurane. A vertebral lesion at the level of the 3<sup>rd</sup> thoracic-lumbar vertebra with vertebral lamina and the vertebral body being involved without compression of the spinal cord, a vertebral lesion at the level of the 7<sup>th</sup> thoracic-lumbar vertebra and a vertebral lesion at the level of the 8<sup>th</sup> thoracic-lumbar vertebra were recorded in the first female. Loss of the shell near the left carapace-plastron bridge, with massive haemorrhage and compression of organs were present in the second female. The remaining four turtles had only superficial lesions with no involvement of bones and organs of the coelom. Computed tomography was proved to be a valuable non-invasive method for clinical examination of stranded sea turtles.

Consensus Genotypes

Estimating population size is particularly difficult for animal species living in concealing habitats with dense vegetation. This is the case for roe deer as for many other ungulates. Our objective was to develop a non–invasive genetic capture–mark–recapture approach based on roe deer faeces collected along transects. In a pilot study, we collected 1,790 roe deer faeces during five sampling days in a forested study area in south western Germany. We extracted DNA from 410 of these samples and carried out microsatellite analysis using seven dinucleotide markers. The analyses resulted in 328 useable consensus genotypes which were assigned to 174 individuals. The population size estimated using a Bayesian approach was 94 (82–111) male and 136 (121–156) female roe deer. Our study shows that non–invasive genetic methods are a valuable management tool for roe deer.

The Brain

In this study we describe the finding of a Cephenemyia stimulator larva in the brain of a roe deer (Capreolus capreolus) after performing a computed tomography (CT) scan of its head. Despite this anatomical location of oestrid larvae could be relatively frequent in other genera, such as Oestrus, to our knowledge, this is the first reported case involving the genus Cephenemyia. Concretely, a second-instar C. stimulator larvae was found in the basis of the cranium. The location of a macroscopic hemorrhagic lesion involving the brain parenchyma peripheral to the location of the larva suggests that tissue colonization occurred before the animal was hunted. Since no detectable alterations or damage to the cranial bones were observed, we suggest a possible larval migration route drilling the skull bones. Finally, we propose the use of the term “neuromyiasis” to be referred to the invasion of the central nervous system by dipteran larvae, particularly oestrids.

Worse Prognosis

Gastroesophageal varices are the most common complication of portal hypertension and associated with a worse prognosis. Endoscopy is the gold standard method to diagnose gastroesophageal varices. However, endoscopy is an invasive method with potential complications and is not well adhered by patients. Non-invasive methods, including serum markers or scores, computed tomography, ultrasonographic, and elastography-based methods, have been explored for the diagnosis of gastroesophageal varices. In the current chapter, we will briefly review non-invasive methods for the prediction of gastroesophageal varices.

AbstractObjectiveTo determine the incidence of nasolacrimal duct injury after functional endoscopic sinus surgery radiologically, using computed tomography.MethodsFifty patients of either sex who underwent functional endoscopic sinus surgery were evaluated for nasolacrimal duct injury by computed tomography. Computed tomography was conducted pre-operatively, and post-operatively at the end of four weeks, and nasolacrimal duct injury was analysed.ResultsThe prevalence of nasolacrimal duct injury dehiscence was 1.16 per cent, with a similar incidence of 1.16 per cent for nasolacrimal duct injury post-operatively. However, no cases of symptomatic nasolacrimal duct injury were recorded.ConclusionComputed tomography scan is an effective, non-invasive method to evaluate nasolacrimal duct injury following functional endoscopic sinus surgery, in accordance with evidence-based medicine.

Geographic Expansion

Cephenemyia stimulator is a Palearctic species developing in the nasal cavity and pharynx of roe deer (Capreolus capreolus). It is widely spread in the range of distribution of this ungulate in Europe. Since the first report of C. stimulator in Spain in 2001, a rapid geographic expansion has been observed, first in the north of the country, with high prevalence and intensities of infestation that caused some mortal cases, and, lately, also in Extremadura and Andalucía, the southernmost populations of European roe deer. These observations suggest an adaptation of this parasite to different ecosystems of the Iberian Peninsula. Almost simultaneously, C. stimulator is also expanding its range to northern Europe, with the first cases being reported in Sweden. Thus, Cephenemyia stimulator may be an example of a parasite currently displaying distributional changes along its southernmost and northernmost range margins. Thus, it is of the utmost importance to unravel all the epidemiological and clinical aspects of this myiasis, as well as implementing surveillance measures including reliable and non-invasive diagnostic techniques to monitor its expansion and adaptation to different ecosystems and/or hosts and to reduce the negative impact on roe deer populations.
