This web-based survey shows a substantial time interval of over one year until diagnosis of Crohn's disease amongst the study participants. This period is characterized by both psychological stress and impaired ability to work.

We conclude that immunosuppression has to be regarded as an independent risk factor for CDI. Immunosuppressive treatment increases the risk of colonisation and infection with Clostridium difficile and leads to a higher relapse rate in patients with CDI.

Aim:The objective of this study was to obtain and compare two-dimensional (2D) and three-dimensional (3D) ultrasonographic images of the urinary bladder in different disease conditions.Materials and Methods:The present study was conducting on total 10clinical cases of the urinary bladder in dogs. The ultrasound (US) machine used for this study was 3D US machine (Nemio-XG: Toshiba, Japan) having a four-dimensional volumetric probe.Results:In the present study, the inflamed thickened wall was clearly visible with the distinction of different layers of the urinary bladder wall in some of the cases of cystitis using 2D ultrasonography. In 3D sonogram, the urinary bladder was visualized as a large anechoic structure with no distinction of different layers of the bladder wall. The cystoliths were clearly visible as hyperechoic structures with distal acoustic shadow in 2D sonogram and appeared as a bright echogenic area in 3D sonogram. In case of urinary bladder neoplasia in 2D ultrasonogram, the bladder lumen was found to be occluded with a large growth imaged as focal anechoic areas in the tissue of mixed echogenicity with small hyperechoic dots in this tissue parenchyma. In 3D ultrasonogram, a tissue of mixed echogenicity of pus was also observed.Conclusion:From the present study it was concluded that 2D and 3D ultrasonography is very helpful for diagnosis of different clinical conditions of the urinary bladder such as cystitis, cystoliths, and urinary bladder neoplasia. The cavity of urinary bladder was more clearly visualized in 3D ultrasonography, but the distinction of different layers of the bladder wall was visualized only in 2D ultrasonography. The distinct shadow of pus and cystoliths were visible in 2D ultrasonogram. The visualization of pus in 3D ultrasonography was done for the first time in present study.

Aim:The objective of the study was to obtain and compare two-dimensional (2D) and three-dimensional (3D) ultrasonographic images of the kidney in different disease conditions.Materials and Methods:In this study, 11 clinical cases of different age groups of dogs suffering from kidney diseases were diagnosed by 2D and 3D ultrasonography at Teaching Veterinary Clinical Complex, Lala Lajpat Rai University of Veterinary and Animal Sciences, Hisar. The ultrasound (US) machine used for this study was 3D US machine (Nemio-XG: Toshiba, Japan) having four-dimensional (4D) volumetric probe. The images were acquired with 3-6 MHz 2D curvilinear transducer and 4.2-6 MHz 4D volumetric curvilinear transducer.Results:Nephritis was diagnosed in four dogs aged between 5 months and 6 years. In all the cases of nephritis diffuse increase in echogenicity of kidney, parenchyma was observed. Two dogs with end-stage kidney disease were also diagnosed. In both 2D and 3D ultrasonography, the kidney size was decreased and architectural details were also lost in them. The cases of regional renal diseases diagnosed were hydronephrosis and nephrolithiasis. Dilated renal pelvis was the common finding in all the three cases of hydronephrosis in both 2D and 3D ultrasonogram. Nephroliths were observed in one case with the history of hematuria and oliguria. The multifocal renal disease diagnosed in this study was dysplastic polycystic kidney. In 2D ultrasonogram, six anechoic cavities appeared with thin strip of renal parenchyma. In 3D ultrasonogram, the cysts appeared as black anechoic areas.Conclusion:The result of the current study showed that the clinical conditions of kidney such as nephritis, end-stage kidney, hydronephrosis, polycystic kidney, and nephrolithiasis can be diagnosed easily using 2D and 3D ultrasonography. Visualization of renal structures was clear in 2D ultrasonography in the conditions of nephritis and end-stage kidney. However, the conditions such as hydronephrosis, polycystic kidney, and nephrolithiasis were visualized clearly in both 2D and 3D ultrasonography equally.
