    Notes: Abstract Objective: Dynamic barium radiology with cine- or video recording has been the most frequently used technique for assessing patients with pharyngeal dysphagia. Although the diagnostic yield of the barium swallow has been high, many patients with pharyngeal dysphagia have normal dynamic barium radiology and remain a diagnostic dilemma. Could manometry add important diagnostic information in these patients? Material and methods: We examined 19 patients (12 men and 7 women, mean age 47 years, range 19–69 years) with pharyngeal dysphagia but a normal barium swallow with simultaneous videoradiography and pharyngeal manometry and compared their manometry to that found in 24 normal volunteers (11 men and 13 women, mean age 37 years, range 23–59 years). Results: Comparing mean values, the patient group showed statistically significant differences from the control group for eight of 10 manometric parameters. Fourteen of 19 patients showed at least one (five patients) and in most cases multiple (nine patients) manometric abnormalities (values exceeding normal mean by ±2SD) which might have contributed to their dysphagia: five patients with high upper esophageal sphincter (UES) resting pressures, five with high LIES residual pressures, three with weak pharyngeal contractions, three with pharyngeal “spasms,” seven with prolonged contraction/relaxation times, five with reduced compliance, and seven with UES/P incoordination. Conclusions: Solid-state computerized manometry is a useful adjunct to videoradiography and can provide potentially important additional information in the diagnosis of dysphagia patients.

    Notes: Abstract Double-contrast examinations of the small bowel were compared with operative specimens obtained within 4 weeks after X-ray evaluation of 20 patients with Crohn's disease. Objective evidence of superficial lesions was submucosal edema and superficial ulcerations observed in the operative specimens. Edema was seen radiographically in 18 of 20 patients. Superficial ulcerations were seen radiographically in 8 of 14 patients. These ulcerations were either single with edematous edges or smaller, multiple, and more uniformly spread. The diagnosis demands a high-quality technique and even then the diagnostic accuracy is not always optimal.

    Notes: Abstract In a retrospective study, films from radiologic examinations of 13 patients with primary adenocarcinoma of the small bowel were reviewed. All patients had a barium examination and in 5 cases angiography was also performed. The barium studies disclosed strictures with overhanging edges in 11 patients, in 4 of whom there was a pronounced prestenotic dilation. Angiographically the predominant findings were in all cases hypovascularity and displacement of vessels. In 4 patients there was also encasement. Neovascularity was present in 2 patients. One patient showed angiographic changes due to intussusception.

    Notes: Abstract The function of the pharyngoesophageal stage of deglutition was studied by cineradiography in 45 patients with an acute onset of dysphagia. None of the patients had any radiographically detectable foreign body in the pharynx or esophagus. In 34 of the patients (76%) a functional or morphodynamic abnormality was disclosed; a defective closure of the laryngeal vestibule (26 patients), defective movements of the epiglottis (18 patients), uncoordinated relaxation of the cricopharyngeal muscle (14 patients), paresis of pharyngeal constrictor muscles (9 patients), and cervical webs (9 patients). In 21 of the patients more than 1 type of dysfunction was present. The results of this study suggest that cineradiography of the pharyngoesophageal stage of deglutition is useful in patients with acute dysphagia, without a foreign body, as functional abnormalities often can explain the patients' complaints.

    Notes: Abstract Background Screening for inflammatory small bowel disease has hereto relied on barium examination, usually performed after duodenal intubation. A noninvasive technique for imaging of the small bowel in such patients would be preferable. Methods A total of 59 patients were included in the study. A small bowel barium examination (SBE) was performed after duodenal intubation using a barium and air double-contrast technique. Ultrasound (US) of the right lower quadrant was performed with a 3.5- or 5-MHz transducer. The patients fasted overnight. Results In 37 of 39 patients with a normal SBE, US was also normal. In 20 patients, SBE showed lesions compatible with Crohn disease and in 18 of these the US study showed thickening of the bowel wall. One of these patients later tested positive for Yersinia enterocolitica. There were two false-positive and two false-negative US examinations. For detection of inflammatory disease of the small bowel, US was calculated to have a sensitivity of 0.95, specificity of 0.93, accuracy of 0.93, predictive value of a positive test was 0.90, and a predictive value of a negative test was 0.95. Conclusions US, therefore, seems to be a reliable method in the workup of patients suspected of having inflammatory small bowel disease. Thereby, US probably can select patients for SBE.

    Notes: Abstract Our purpose was to assess the role of MRI in evaluating themusculoskeletal system in athletes with chronic pain laterally in the groin of unknown etiology. Magnetic resonance imaging (MRI) of the pubic ring was performed in 11 young athletes (soc cer players) with long-standing groin n pain. MR findings were: compared with plain films and isotope examination (bone scan Tc 99M). Abnormal MRI findings included a broadend andirregular symphysis witha characteristics pattern of low signal intensity on T1W and high signal intensity on T2W images localized in the superior pubic ramus at a distance from the symphasis. Positive findings wer also observed on plain films and on nuclear medicine studies. However, the imaging findings in the superior pubic ramus of the symphysis was located considerably more laterally on MRI. MRI is :a valuable method for evaluating discrete and ambiguous pelvic pain in athletes. particularly for identifying concomitant changes in the superior ramus, which may give rise to long-standing localized laterally in the groin.

    Notes: Male rats, 21-100 days old at the start of different experiments, were kept for several weeks on synthetic diets, either adequate, or deficient in calcium (Ca) and at the same time low in protein and high in sucrose.For varying parts of the experimental periods the rats were given either dist. water, or water supplied with 2000 ppm Ca, 40 ppm fluoride (F), or both in a compatible form.Assessment was made of several parameters of the femoral bone density and of two histometric parameters of the alveolar bone density.The bone density in animals on Ca-deficient diet was greatly improved by supplying either Ca or Ca+F with the drinking water. There was a tendency to higher mineral density with Ca+F supply than with Ca alone. Rats that had been on a high F, adequate diet were much more resistant to bone mineral depletion by a subsequent Ca-deficient diet than were control rats that had been on the same diet without F.The alveolar bone generally reacted more strongly than the femoral bone to both deprivation and supplementation, and the tissue between the roots of one molar (M 2) more than the tissue between two molars (M 1–2).The correlations of alveolar bone parameters to femoral weight, ash, Ca and P content were all positive, in most cases statistically significant, and generally stronger for the M 2 than for the M 1–2 tissue. In an experiment where the deficient diet was supplied either as powder or as bread the results seemed to support the concept of an influence of masticatory force, particularly on the interdental bone septa.The connection between generalized osteopenia and alveolar bone loss and the roles of Ca and F are discussed.

    Description / Table of Contents: Zusammenfassung. Die Röntgenuntersuchung des pharyngo-oesophagealen Segments bei Patienten mit Dysphagie beruht auf der Auswertung von Morphologie und Funktion. Dazu sind video- oder kinematographische Techniken notwendig. Das Zurückhalten von Kontrastmittel oberhalb des cricopharyngealen Muskels kann durch ein kleines Pseudo- oder ein echtes Divertikel verursacht werden. Beide Phänomene werden durch Dysfunktion im pharyngo-oesophagealen Segment hervorgerufen. Damit sich das Pseudodivertikel zu einem echten Divertikel entwickelt, bedarf es wahrscheinlich eines angeborenen Defektes zwischen den Muskelschichten im pharyngo-oesophagealen Segment.
    Notes: Summary. Radiology of the pharyngoesophageal segment in patients with dysphagia relies on evaluation of both morphology and function. Video- or cineradiographic techniques are necessary. Retention of contrast material above the cricopharyngeal muscle can be due to small pseudodiverticula or true diverticula. Both phenomena are due to dysfunction in the pharyngoesophageal segment. To develop into a true diverticulum it is probably necessary to have a congenital defect between the muscle layers in the pharyngoesophageal segment.

    Notes: Abstract. The aims of the present study were to assess if MRI gives the same diagnostic information as herniography concerning the presence of hernias and reveals other causes of groin pain. The prospective study enrolled 20 patients referred for herniography, 6 women and 14 men, mean age 48 years. After herniography the patients underwent MRI using T1-weighted, fat-suppressed inversion recovery (STIR), and magnetic resonance cholangiopancreaticography (MRCP) pulse sequences. No contrast medium was administered at MRI. Herniography revealed 11 hernias and MRI depicted 8 of these. Magnetic resonance imaging depicted well the anatomy in the groins. In 3 patients where hernias were not revealed, MRI revealed inflammatory changes in the symphysis region as a possible cause of groin pain. The primary diagnostic tool for diagnosing hernias is herniography. If the herniogram is normal, MRI may reveal other causes of groin pain and may also better visualize related structures in the groin.
