    Opis:
    Background: In malrotation the position of third portion of duodenum (D3) is always intramesenteric. Demonstration of normal retromesenteric-retroperitoneal position of D3 on ultrasound (US) can rule out malrotation. The aim of this study was to evaluate the feasibility of US in demonstrating the retroperitoneal D3. Material and Methods: Abdominal US study was done for various indications in 60 newborns and infants (mean age: 33 days [range: 4-100 days]; 56.7% male) by an expert pediatric radiologist. The position of D3 and its adjacent structures was evaluated in axial and longitudinal planes by linear and curved transducers. Results: A normal retromesenteric-retroperitoneal D3 located between the superior mesenteric artery and the aorta was seen on US in all patients, including those with extensive gas in the bowel. The mean time of D3 observation was 47.8 s (10-180 s). Ultrasound was also capable of demonstrating D3 structure, diameter, content, adjacent structures, relative position of the superior mesenteric artery and vein. Conclusions: Ultrasound is a simple, fast and highly accurate tool to confirm the retroperitoneal position of D3. Ultrasound can be used as a screening method for malrotation eliminating the need for unnecessary barium studies.

    Opis:
    Herein we reviewed the computed tomography (CT) findings of a spectrum of pathological entities affecting the duodenum. We discuss the CT findings of some congenital, inflammatory, traumatic, and neoplastic pathologies of the duodenum along with the conventional barium studies of selected conditions. Pathologies of this C-shaped intestinal segment, derived from both foregut and midgut, are often overlooked in clinical practice and radiological literature. While congenital anomalies like duplication cysts and diverticula are usually asymptomatic, annular pancreas and malrotation may manifest in the first decade of life. Primary as well as secondary involvement of the duodenum by various disease processes can be evaluated by careful CT technique and proper attention to the duodenum. Among congenital conditions, annular pancreas, duplication cyst, superior mesenteric artery syndrome, midgut volvulus, and diverticula are presented. Duodenal involvement in adenocarcinoma, lymphoma, gastro­intestinal stromal tumours, Crohn's disease, and groove pancreatitis are discussed. Duodenal wall haematoma and traumatic duodenal perforation causing pneumoretroperitoneum in two patients after blunt trauma of the abdomen are also illustrated. CT provides superb anatomic detail and offers high diagnostic specificity for the detection of duodenal pathologies because it allows direct imaging of the intestinal wall, secondary signs of bowel disease within the surrounding mesentery, and abnormal findings in adjacent structures. Primary duodenal malignancies and local extension from adjacent malignancies can be diagnosed by CT reliably. CT also plays a vital role in the diagnosis of traumatic duodenal injury by differentiating between mural haematoma and a duodenal perforation because the latter requires immediate surgical intervention.

    Opis:
    During 1986-1990 blood samples of 390 brown hares Lepus europaeus Pallas, 1778 were collected in 5 hunting areas in Poland. The blood cells were removed and the resulting serum of plasma protein were separated by electrophoresis in polyacrylamide gels.
