Pelvic floor imaging: comparison between magnetic resonance imaging and conventional defecography in studying outlet obstruction syndrome.

PURPOSE: This study prospectively compared the diagnostic capabilities of magnetic resonance (MR) imaging with conventional defecography (CD) in outlet obstruction syndrome. MATERIALS AND METHODS: Nineteen consecutive patients with clinical symptoms of outlet obstruction underwent pelvic MR examination. The MR imaging protocol included static T2-weighted fast spin-echo (FSE) images in the sagittal, axial and coronal planes; dynamic midsagittal T2-weighted single-shot (SS)-FSE and fast imaging employing steady-state acquisition (FIESTA) cine images during contraction, rest, straining and defecation. MR images (including and then excluding the evacuation phase) were compared with CD, which is considered the reference standard. RESULTS: Comparison between CD and MR with evacuation phase (MRWEP) showed no significant differences in sphincter hypotonia, dyssynergia, rectocele or rectal prolapse and significant differences in descending perineum. Comparison between CD and MR without evacuation phase (MRWOEP) showed no significant differences in sphincter hypotonia, dyssynergia or enterocele but significant differences in rectocele, rectal prolapse and descending perineum. Comparison between MRWEP and MRWOEP showed no significant differences in sphincter hypotonia, dyssynergia, enterocele or descending perineum but significant differences in rectocele, rectal prolapse, peritoneocele, cervical cystoptosis and hysteroptosis. CONCLUSIONS: MR imaging provides morphological and functional study of pelvic floor structures and may offer an imaging tool complementary to CD in multicompartment evaluation of the pelvis. An evacuation phase is mandatory.

Endometrial carcinoma: MR staging and causes of error.

PURPOSE: This study was undertaken to prospectively determine the diagnostic capabilities of magnetic resonance (MR) imaging in detecting myometrial and cervical invasion and lymph node involvement in endometrial carcinoma and to identify the causes of errors in staging endometrial carcinoma. MATERIALS AND METHODS: Twenty consecutive patients with a histological diagnosis of endometrial carcinoma underwent preoperative MR imaging. MR findings were compared with surgical staging, considered as the standard of reference. RESULTS: In assessing myometrial invasion, MR imaging showed 70% accuracy, 80% sensitivity, 40% specificity, 80% positive predictive value (PPV), and 40% negative predictive value (NPV). In detecting cervical invasion, MR imaging had 95% accuracy, 100% sensitivity, 94.4% specificity, 66.7% PPV, and 100% NPV. In evaluating lymph node involvement, MR imaging showed 100% accuracy, sensitivity, specificity, PPV and NPV. Errors in evaluating myometrial invasion were caused by polypoid tumour, adenomyosis and leiomyomas, whereas those in evaluating cervical invasion were caused by dilatation and curettage. CONCLUSIONS: MR imaging is a reliable technique for preoperative evaluation of endometrial carcinoma. Its main limitation is differentiating between stage IA and IB carcinomas, which is not highly important for surgical planning. Cooperation between the gynaecologist and radiologist is mandatory to avoid staging errors.

Chronic anaemia and adhesion molecules in patients with liver cirrhosis. A preliminary report.

AIM: The aim of our study was to investigate circulating levels of intercellular adhesion molecule-1 (sICAM-1) and vascular cellular adhesion molecule-1 (sVCAM-1) in cirrhotic patients, with and without chronic anaemia, to establish whether there was a relationship between inflammatory activity and anaemia. METHODS: We investigated 14 anaemic (mean hemoglobin value 10.65+/-1.06 g/dL) and 14 non anaemic (mean hemoglobin value 13.8+/-0.89 g/dL) subjects affected by virus C-related liver cirrhosis comparable for sex, age and degree of liver dysfunction such as expressed by Child-Pugh classification. Circulating sICAM-1 and sVCAM-1 were measured by EIA commercial kit (R&D System Co, Abington, UK) and mean+/- standard deviation values in two groups were compared by t-test and Kruskall-Wallis test. RESULTS: Mean+/-standard deviation sICAM-1 was 35.06+/-4.06 ng/mL in anaemic and 23.39+/- 6.1 ng/mL in non anaemic cirrhotic patients. Mean+/-standard deviation sVCAM-1 was 47.66+/-8.18 ng/mL in anaemic 31.77+/-6.08 ng/mL in non anaemic patients, respectively. Statistical analysis showed a significant difference between the two groups both in sICAM-1 (p=0.01) and sVCAM-1 (p=0.03) values. CONCLUSIONS: Our study show that chronic anaemia, in liver cirrhosis, is associated to a greater increase of circulating adhesion molecules and suggests that inflammation may contribute to persistence of anaemic state, worsening the outcome of cirrhotic patients.

The use of nimodipine (Nimotop-Bayer) in patients with chronic ischemic cerebral vasculopathies. Twenty-eight case reports.

Nimodipine therapy (30 mg x 3/die) was commenced in twenty-eight patients affected by chronic ischemic cerebral vasculopathies and continued for the 90 days in order to evaluate drug efficacy. Clinical controls were carried out 4, 8 and 12 weeks after the start of therapy using Doppler, ultrasound and neurological tests (the letter based on the SCAG neurological scale). Hemodynamic and hematochemical parameters were also monitored and controlled.

Vesico-ureteral reflux: diagnosis and staging with voiding color Doppler US: preliminary experience.

INTRODUCTION: The aim of this study is to assess the accuracy of a new US examination: 'voiding color Doppler US ' in the early diagnosis and staging of vesico-ureteral reflux (VUR). The contrast agent US was SH U 508A (Levovist, Schering, Berlin), which produces a chromatic accentuation of the signals picked up by the color Doppler US. Eighteen patients (10 females, eight males) were recruited for the study. In two patients a second examination was performed for follow-up after a VUR conservative therapy. All patients were taken under examination for the evaluation of possible VUR. In all patients the voiding color Doppler US was followed by voiding cystourethrography (VCUG) and the data obtained were compared. MATERIALS AND METHODS: A total of 18 patients aged between 3 months and 10 years, were recruited for the study. The results of the examination were the following: urinary tract infections, follow-up of VUR after conservative or surgical therapy, miscellaneous indications. Voiding color Doppler US was performed, followed by a VCUG. The voiding color Doppler US consists in the trans-catheter introduction of a contrast agent SHU 508 A (Levovist, Schering, Ag. Berlin) into the bladder and a subsequent test with the color Doppler US to show or exclude the presence of reflux into the ureters and/or into the pyelo-caliceal cavity of the kidneys. After the introduction of the contrast agent US the ultrasound scanning of the bladder, the ureters and the pyelo-caliceal cavity was performed to examine the reflux degree. The ultrasonographic investigations were perfomed with AU 590 asyncronus US (Esaote Biomedica, Genova) with a 3.5 MHz convex probe. RESULTS: After the trans-catheter introduction of the contrast agent US, vesico-ureteral reflux occured in 13 patients (77.2%). The reflux degree was also measured by means of ultrasound and was later confirmed by VCUG. The mean times of each examination were as follows: initial US, 10 min; catheterization, 8 min; voiding color Doppler US, 15 min; overall VCURG examination 10 min. The overall mean duration of the voiding color Doppler US examination was 33 min. The comparable mean time for VCUG, including the catheterization time, was 20 min. No reactions of intolerance to the ultrasound contrast agent occurred. DISCUSSION AND CONCLUSIONS: The voiding color Doppler US test has evidenced in all patients the presence of the contrast agent US in the bladder after the introduction. In 13 patients (77.2%) with presence of VUR, the voiding color Doppler US test has established the reflux degree confirmed by cystourethrography. The superimposability of the data obtained with voiding color Doppler US and VCUG would seem to confirm the importance of this new ultrasonographic technique in the diagnosis and staging of VUR.

[Familial Marfan's syndrome. A critical review and presentation of a clinical case]. / Sindrome di Marfan familiare. Revisione critica e presentazione di un caso clinico.

Aim of this paper is to describe and discuss, on the basis of an exhaustive review of literature, the case of a 14-year-old girl with familiar Marfan's syndrome. This disease is a generalized inherited disorder with involvement of connective tissue and symptoms affecting ocular, skeletal and cardio-vascular systems, usually diagnosed in young age and associated with a poor prognosis because of late severe aortic complications (dissection, dilation or aneurysms, regurgitation, etc.). The young patient sought to our medical attention because of severe leanness, delayed menarca and irregular menstruations; physical examination disclosed the typical "morphotype of Marfan" with long limbs, slenderness of hands and feet, severe kyphoscoliosis, narrow chest with "pectus excavatum", marked hyperextensible joints, and high arched palate with malocclusion. Echocardiography demonstrated a mild mitral valve prolapse. The 43-year-old patient's mother presented an undiagnosed Marfan's syndrome, despite typical morphotype, muscle-skeletal alterations and moderate dilation of ascending aorta. The maternal grand-mother deceased prematurely for cardiopathy of unknown origin. It is stressed that the disease should not be underestimated, because the early diagnosis is important for the patient's prognosis, allowing the early preventive surgical intervention for correcting aortic or valvular alterations. The echocardiography represents a sensitive and noninvasive mean, useful to manage the patients with proven or suspected aortic dilation. The subjects with Marfan's syndrome who exhibit rapid progression of aortic dilation, or an aortic diameter in excess of 50 mm, should be considered for an elective surgical intervention (at low mortality and suitable to increase remarkably the lifetime expectation). Women with syndrome of Marfan should be advised on the high cardio-vascular risk during pregnancy.

[Diffuse symptomatic polypoid lipomatosis of the colon with hyperplasia of epiploic appendices: a case report]. / Diffusa e sintomatica lipomatosi polipoide del colon con iperplasia delle appendici epiploiche: descrizione di un caso clinico.

Diffuse and symptomatic lipomatosis of the colon, particularly when associated with hyperplasia of the appendices epiploicae, is a rare disease. We report here the case of a lean, 26-year-old woman who had polypoid lipomatosis of the colon with submucosal and subserous expression (involving the mesentery and peritoneum) associated with extreme hyperplasia of the appendices epiploicae. Her disease led to a recurrent subocclusive syndrome which required total colectomy. We discuss the case and review the literature on this subject. The particular characteristics of this case and early onset of disease would suggest that our patient was affected by a congenital lipomatous syndrome linked to mesenchymal dysplasia. Long-term monitoring will enable prompt intervention in the case of reformation of lipomatous tissue.

[Indications and limitations of bronchography in surgery of carcinoma of the lung]. / Indicazione e limiti della broncografia nella chirurgia del carcinoma del polmone.

Starting from a consecutive series of 53 bronchographies performed under local anesthesia, in subjects with carcinoma of the lung ascertained by operation, the Authors analyse both the bronchographical aspects which most frequently come under the surgeon's observation, and the usefulness of this investigation in formulating the operating plan. As regards carcinomas of the large and medium bronchi, the bronchographic aspects they found most frequently are occlusion (82%) both in the form of sudden arrest and in the form of a cone image and stenosis (18%). In peripheral carcinomas, on the other hand, most characteristic bronchographic signs are identified as occlusion (58%) (amputation and stenosis) and dislocation (38%) with rigidity of one or more small calibre bronchi (rigid impairment). On the basis of their experience the Authors conclude that bronchography constitutes an almost indispensable examination for diagnostic purposes in malignant neoplasias, especially in the initial stage, when located outside the field of action of bronchoscopy, and can supply elements indispensable in the preoperative operatability judgement. In fact it not only gives very reliable information on the anatomical situation of the bronchus, as well as on the site and presumed starting-point of the neoplasia, but also supplies more approximate elements with regard to the extent of the neoplasia and any presence of lymphoglandular metastases.

[Postoperative hyperkinetic arrhythmias treated with amiodarone]. / Aritmie ipercinetiche insorte nel periodo postoperatorio trattate con amiodarone.

Twenty eight patients have been treated; 8 patients had atrial fibrillation (FA) and 20 supraventricular paroxysmal (SVPT) tachycardia. Both diseases followed interventions of major surgery. No patient had myocardial ischemia and/or damaged conduction system, took any heart-related drug, or showed any risk factor. The posologic plans was as follows: a) bolus i.v. (three minutes) with 2 Amiodarone vials and electrocardiographic monitoring, then b) 10-20 mg/kg/day for three days with electrocardiographic monitoring. Within 5 days, all patients attained the total recovery from SVPT; AF regressed during the bolus injection in 1 patient, on the first day in 5 patients, and on the third day in the remaining 2 patients. During the hospitalization no important side effects occurred, except for transient hypotension in three subjects. The 6 months follow up did not reveal signs of intolerance, either. Amiodarone thus showed to be useful and well tolerated in the treatment of post-surgical hyperkinetic arrhythmias in patients undergoing major surgery.
