ABSTRACT

We report the case of an 82-year-old female presenting with acute epigastric abdominal pain after traumatic blow on the epigastrum. High-resolution multimodal imaging comprising Ultrasound, CT and MR, correlation with laboratory blood analyses and a 6 months CT follow-up allowed us to make a definite diagnosis of traumatic heterotopic pancreatitis. This case emphasizes the relevance of a well-targeted high-definition ultrasound study in the following of the first imaging modality.

ABSTRACT

We have deposited Au films in ultra-high vacuum onto a rhenium ([Formula: see text]) surface in submonolayer and multilayer concentrations and studied them by means of low- and medium-energy electron diffraction in the temperature range between 300 and 800 K. In the submonolayer range, Au forms several low-energy electron diffraction (LEED) phases, namely, a (1 × 3), a (1 × 4), a (1 × 5) and a (1 × 6) phase, consisting of one-dimensionally ordered Au chains in the [[Formula: see text]] direction, until the formation of a complete pseudomorphic monolayer is indicated by a (1 × 1) LEED phase. In the multilayer regime, a (1 × 8) LEED phase appears over a surprisingly wide coverage range from about two to at least eight monolayers, which we interpret as a hexagonal uniaxially compressed reconstructed Au overlayer on pseudomorphically grown hexagonal close-packed gold layers. In order to get access to absolute Au coverages, we have performed LEED (I,V) measurements and carried out a LEED structure determination for the (1 × 1) phase. We propose the formation of a full Au monolayer in which both the Re trough and top-row sites are being covered by Au atoms. The data are discussed and compared with those from previous studies on related systems.

ABSTRACT

We investigated psychophysiological responses to fear and anger inductions during real-life and imagination. Female participants (N = 158) were assigned to a fear-treatment, fear-control, anger-treatment, or anger-control group. Context (real-life, imagination) was varied in two sessions of fixed order. Eleven self-report and 29 somatovisceral variables were registered. Results showed that (a) except during anger imagination, control groups were emotionless; (b) in control groups, contexts prompted diverging somatovisceral responses, but similar emotion self-reports; except during fear imagination, the emotion inductions (c) were successful and (d) produced specific emotion reports; (e) during real-life, somatovisceral fear and anger responses exhibited a marked cardiovascular defense reflex; (f) in addition, real-life fear showed an adrenaline-like specific response pattern, whereas real-life anger showed specific forehead temperature and EMG extensor increases, accompanied by an elevated DBP during imagination. A Component Model of Somatovisceral Response Organization is proposed.

ABSTRACT

The aim of this study was to analyze the color Doppler sonographic findings in primary epiploic appendagitis. Color Doppler sonographic findings of ten patients with primary epiploic appendagitis were reviewed. The following sonographic features were analyzed: identification of a mass adjacent to the colonic wall; identification of spotty color areas with arterial flow in this mass and detection of abnormalities of the colonic wall adjacent to the infiltrated fatty tissue. A well-delineated hyperechoic mass adjacent to the colonic wall was detected in each patient with sonography. No colonic wall abnormalities were observed nor color Doppler signal in and around the hyperechoic area. Absence of flow at color Doppler sonography is an additional feature of epiploic appendagitis.

ABSTRACT

Pancreaticopleural fistula secondary to chronic pancreatitis is a rare cause of recurrent pleural effusion. The demonstration of the fistula with endoscopic retrograde pancreatography and CT is invasive or limited. We report in two patients the use of magnetic resonance pancreatography as a noninvasive alternative to endoscopic retrograde pancreatography for the diagnosis of pancreaticopleural fistula.

ABSTRACT

We describe a case of pancreatic cystosis in an 18-year-old man suffering from cystic fibrosis, who presented with acute epigastric pain. Ultrasound and computed tomographic studies revealed multiple pancreatic cysts of various size, measuring up to 5 cm. Pancreatic macrocystosis is an extremely rare manifestation in cystic fibrosis.

ABSTRACT

The high diagnostic ability of sonography for the solid organs of the upper abdomen and the biliary and genitourinary tract is well established. The gut on the other hand has been more or less ignored by many sonographers in routine abdominal screening and evaluation of the acute abdomen. This is regrettable because sonography, like CT, is an excellent modality for assessing mural abnormalities of various origin (i.e. neoplastic, inflammatory, ischemic or hemorrhagic), as well as possible involvement of the adjacent soft tissues and solid organs. Considerable sonographic skill and "tenacity" and an adequate equipment are however indispensable to achieve high diagnostic reliability in the detection and interpretation of abnormalities of the G-I tract. Our own and other's experience suggest that the time devoted to sonographic screening of the gut is very worthwhile especially in acute clinical conditions. Acute appendicitis is one of the typical examples where sonography has found widespread acceptance. This article reviews the application of graded compression sonography in the evaluation of appendicitis, for using on technique, diagnostic criteria, and differential diagnosis.

ABSTRACT

The sensitivity of ultrasonography (US) as the initial imaging procedure in acute diverticulitis of the left colon was retrospectively compared with that of computed tomography (CT) in 34 patients. Final diagnosis was based on clinical findings and follow-up in a first group of 20 patients with mild diverticulitis, and was proved by surgery in a second group of 14 patients with severe diverticulitis. In the first group, US showed findings consistent with diverticulitis in 19 patients, as did CT. The image of an inflamed diverticulum was shown by US in 10 patients. In the surgical group, findings consistent with diverticulitis were shown by US in 11 cases, and by CT in 13 cases. An inflamed diverticulum was not detected at US in this group of patients, presumably because the diverticulum was incorporated in the inflammatory process. These results suggest that US is a valuable technique in the initial evaluation of patients suspected of having acute diverticulitis, especially when the disease is not severe. The image of an inflamed diverticulum shown at US strongly suggests the diagnosis of mild diverticular disease. When diverticulitis is severe, CT should be performed in addition to US.

ABSTRACT

Seventeen kidneys removed from patients with renal carcinoma were submitted to ex vivo ultrasonography and then to serial pathological examination in an attempt to detect secondary tumours in apparently normal tissue. Ex vivo ultrasonography failed to reveal further tumours, but 2 lesions measuring 5 and 8 mm were found on pathological examination. These preliminary data suggest that intra-operative ultrasonography may be of little value in detecting secondary tumours in conservative surgery for renal carcinoma.

ABSTRACT

A single-blind study was conducted in 52 hypertensive patients, aged 25 to 68 years, to compare the side effects of an equally effective antihypertensive regimen of propranolol and atenolol. All patients had a history of side effects with beta-blocker therapy. Patients were treated with propranolol 40 to 160 mg bid for 8 weeks, followed by atenolol 50 to 100 mg given once daily for 8 weeks, and then rechallenged with the required dosage of propranolol for 8 weeks. Mean systolic and diastolic blood pressures were controlled during all three treatment phases. Side effects showed a definite trend toward improvement during the atenolol treatment phase. CNS side effects, in particular, showed significantly (P less than .05) reduced severity scores and overall incidence rates during the atenolol treatment phase. In conclusion, this study showed that at equally effective antihypertensive dosages the hydrophilic beta blocker atenolol produced significantly fewer CNS side effects than the lipophilic beta blocker propranolol.

ABSTRACT

Liver ultrasound was prospectively evaluated in 104 subjects who underwent liver biopsy, including 24 patients without evidence of liver disease (controls), and 80 with a broad spectrum of liver pathology. Ultrasonography was very specific (100%) and moderately sensitive (70%) in the detection of liver pathology, and hepatic neoplasms, steatosis, and fibrosis were detected by ultrasound in 80%, 80%, and 67% of cases respectively. In addition, ultrasonography diagnosed other pathologies--mainly biliary tract disease and abdominal neoplasms--in 26% of the patients.
