Abstract
BACKGROUND To evaluate the efficacy of extracorporeal shockwaves therapy (ESWT) in patients with chronic painful shoulder. METHODS EXPERIMENTAL DESIGN a prospective design was used with a short term follow-up. SETTING data were collected at the Service of Physioterapy in Villa Stuart Clinic-Rome. PATIENTS 72 patients of both sexes with an average age of 38 years (range 18 to 69) affected by chronic painful shoulder, whose symptoms lasted more than 6 months. INTERVENTIONS all patients received on average, 2,000 impulses of ESWT at level 5 energy (0.21 mJ/mm2) according to Dornier Epos equipment one session per week for 8 weeks. MEASURES all cases underwent an instrumental examination with X-ray conventional imaging and clinical assessment of pain (visual analogue scale) and functional limitation of the shoulder, two weeks before the treatment and at one month follow-up. RESULTS 53% of patient scored excellent results, 14% good, 13% fair and 20% poor. In the group of calcifying tendinitis we had a reduction in 37% and no changes in 63%. CONCLUSIONS Even with a limited number of cases our early results show the efficacy and safety of ESWT in the treatment of chronic painful shoulder resistant to other conservative approaches.

Abstract
BACKGROUND Tumors of the head of the pancreas and of the periampullary region, similar nosologic entity, represent the fourth most common cause of cancer death. These tumors are characterized bt high mortality rate associated with a low percentage of surgical resectability. Vascularly involvement is, in our experience, one of the criteria of exclusion for curative surgical resection. For this reason regional pancreasectomy don't show, in several case records, comforting datas about survival. METHODS From 1995 to 1998 we introduced in the operative practice the color--doppler ultrasonography to diagnose vasculary involvement. We evaluated twenty patients that previously were candidated for surgical therapy consisting in a duodenal-pancreasectomy. All the patients were staged by preoperative abdominal ultrasound, E.R.C.P., CT, and angio M.R.I.. In no one of these patients were founded signs of vascularly involvement. We recognized by intraoperative color-doppler ultrasound three microscopic invasions of spleno-mesenteric-portal vasculary axis. RESULTS U.S. I.O. C.D. in our case reports has underlined a sensibility and specificity of 100%. It has discovered, also, a false positive for neoplastic thrombosis, and a case of false negative. CONCLUSIONS Intraoperative ultrasound shows a high sensibility about the intraoperative staging for the bibliopancreatic tumors. The study about the possible vascularly involvement is helped by the application of the colour in terms of an high sensibility and diagnostic care.

Abstract
We studied the effects of pre-treatment (15 days) with oral administration of Ginkgo biloba extract (Ph-Gb 37.5-150 mg/kg) on brain malonildialdehyde (MDA), brain edema, brain nitrite and nitrate and delayed neuronal death following transient cerebral ischemia in the Mongolian gerbil. Survival was not modified, however, pre-treatment with Ginkgo biloba significantly and in a dose-dependent way reduced post-ischemic brain MDA levels and post-ischemic brain edema. Delayed neuronal death in the CA1 of the hippocampus was attenuated by the highest dose of the extract. Increase of nitrite and nitrate was observed after cerebral ischemia in the hippocampus and it was dose-dependently reduced in animals pretreated with Ph-Gb, thus suggesting that neuroprotective effects of Ginkgo biloba may be due to an inhibitory action on nitric oxide formation.

Abstract
BACKGROUND After having abandoned conservative operations of the thyroid (partial resection, enucleal resection) today total thyroidectomy and sub-total thyroidectomy and near total thyroidectomy are the operations of choice. Cause the frequent post-operative scintigraphic signs, on the 3rd month, of thyroidal residue of significative size, founded in our patients operated for sub-total thyroidectomy, we begun to study the echografical monitoring of the thyroidal recess. METHODS From January 1995 to December 1997 we operated 200 patients for Thyroidectomy. The kinds of operations were: total thyroidectomy for 96 patients (48%), sub-total thyroidectomy for 64 patients (32%), and near total thyroidectomy for 40 patients (20%). We controlled all the patients by ecografical monitoring of the thyroidal recess to detect and to determinate the possible thyroidal residue, that it will be monitorized on the 7th day, on the 1st month, on the 6th month and on the 12th month. We measured the thyroidal residual dimensions and volume. We recorded all the examinations by VCR or film and after we elaborated the results by exponential graphics. The patients that showed the thyroidal residues underwent to a scintigraphy. RESULTS The thyroidal residuals were measured within the 7Th post-operative day. In the following controls we have noted a thyroidal residue hypertrophy. Multinodular goither was the disease with the highest degree of growth (until the 200% of the first measure of the residue). After an initial phase of growth almost all the patients showed a trend to the stabilization, with the exception only of the patient that suffered from multinodular goither. The scintigraphic examination was not realiable, in our experience, about the mathematic measurement of the thyroidal tissue, showing always an overvaluation of the residue. The best specificity was showed by US-HR. CONCLUSIONS The patient that undergoes to total thyroidectomy needs an adequate suppressive and substitutive therapy. We identify the presence of several stimulating factors the growth of the residual thyroidal tissue that could arise to promote the hyperplasia and the hypertrophy of the parenchyma (EGF, TSG, TSI, PG). There are factors that are unidentified and are not subject to the suppression caused by substitutive therapy.

Abstract
Erythropoietin prevents in vitro glutamate-induced neuronal death and could play a role in the central nervous system. We investigated the in vivo effects of recombinant human erythropoietin after intraperitoneal (i.p.; 25-100 U) or intracerebroventricular (i.c.v.; 0.25-25 U) administration on survival, brain malonildialdehyde (MDA) levels, brain edema, hippocampal neuronal death and brain nitric oxide (NO) synthesis after bilateral carotid occlusion (5 min), followed by reperfusion in the Mongolian gerbil. Peripheral posttreatment with recombinant human erythropoietin reduced postischemic MDA levels, brain edema and increased survival. Either peripheral or i.c.v. posttreatment with recombinant human erythropoietin significantly reduced hippocampal CA1 neuronal loss, observed 7 days after the ischemic event. Increase of nitrite and nitrate (as an index of NO formation) in the hippocampus, as observed after ischemia, was reduced in animals treated with recombinant human erythropoietin. These data suggest that in vivo recombinant human erythropoietin effects on brain ischemic injury could be due to inhibition of NO overproduction.

Abstract
Bilio-pancreatic (BPD) tumours are pathologies with an overall resectability rate of 20-25%, with a high percentage of patients directed towards palliative treatment (70-90%). One hundred and twenty-eight patients underwent palliative treatment for BPD tumours. The M:F ratio was 1:1.5 and the mean age 61 years. The tumours were topographically divided into: 84 (63%) localised in the pancreatic head region; 34 (25%) biliary duct tumours and 6 arising in the ampulla of Vater. 42 patients (30%) underwent palliative surgical treatment (group 1) and 86 (70%) received non-surgical treatment (endoscopic percutaneous) (group 2). We also performed 6 gastrointestinal by-passes (GEA). The early morbidity rate was 36% in the first group and 12.8% in the second. The incidence of late morbidity in the first group was nil, with a mean survival of 10 months. Mortality was nil in both groups. Surgical by-pass is advisable in the presence of patients with a longer life expectancy and in good clinical condition but presents a high rate of early morbidity and a low percentage of late complications. The authors conclude that validity of the methods is similar. They believe that, in selected cases, surgical treatment remains the therapy of choice for BPD tumours.

Abstract
This was an open-label randomized Phase III study of 207 patients with either unresectable or metastatic non-small cell lung cancer (NSCLC) who were treated with docetaxel plus best supportive care (BSC) or best supportive care alone. Patients in the chemotherapy arm of the study received docetaxel 100 mg/m(2) as a 1 h intravenous infusion every 21 days until they showed evidence of progressive disease, or estimated maximum benefit obtained or unacceptable side effects. Patients who received docetaxel were pretreated with oral dexamethasone. Patients in the BSC arm should not receive chemotherapy or anticancer therapy except for palliative radiotherapy. Overall survival obtained in the docetaxel arm was significantly longer than in the BSC arm (P=0.026). Two-year survival in the docetaxel arm was 12%, whereas none of the BSC patients survived after 20 months. The response rate was 13.1% (95% CI, 7.5-18.8%). There was a significantly longer time to progression in the docetaxel versus the BSC arm (P<0.001), and statistically significant improvement of clinical symptoms with docetaxel compared to BSC. The quality-of-life descriptors were in favor of docetaxel, and the difference was significant for pain, dyspnea and emotional functioning. The safety profile of docetaxel for this study was similar to that already reported in this patient population.

Abstract
UNLABELLED Preoperative staging plays an important role in the surgical treatment of rectal cancer. The most sensitive imaging techniques currently available are CT, MRI and transanal ultrasound (TAUS). The aim of the study was to evaluate the sensitivity and specificity of TAUS in the preoperative staging and postoperative follow-up of rectal cancer. METHODS From January 1992 to May 1999, TAUS was used to study 100 patients with rectal cancer. RESULTS Patients were staged according to the Astler-Coller classification: 1) A: 8 patients; 2) B1: 16 patients; 3) B2: 22 patients; C1: 30 patients; C2: 24 patients. The sensitivity and specificity of TAUS in the preoperative staging of these tumors were 96% for the T parameter, and 100% for the N parameter. The N but not the T parameter results are in line with the values reported in the international literature. CONCLUSION Transanal ultrasound, in our personal experience, has proved to be a very accurate imaging technique in the preoperative staging and postoperative follow-up of rectal cancer.

Abstract
INTRODUCTION Splenic abscesses are very rare pathologies encountered in daily clinical practice. The treatment, after failure of other medical treatments, has basically been surgical, in spite of large diffusion of percutaneous echo and CT techniques. The initial hesitation in applying this sort of method was caused by an unfounded fear of difficult management of haemorrhagic complications. METHODS In our Clinic we treated 6 postoperative abscesses, observed in 5 patients. One of these (16%) was double and 3 concomitant with other intraperitoneal abscessual septic collections, which received priority in percutaneous treatment. In four cases (67%), Van-Sonnemberg drainage catheters were placed which caliber varied from 12 to 14 F. In the remaining two cases, we evacuated the abscess using an echo-guided needle puncture. In two cases we applied fibrinic glue; in one case as a haemostatic agent and in the other, to protect the wide abscessual cavity. RESULTS We recorded the resolution of the symptomatology and instrumental findings in all patients. One patient died two weeks later due to unrelated causes. We recorded one minor complication which involved an intra-abscessual haemorrhage, which was then treated by fibrinic glue (Tissucol). CONCLUSION Echo-guided percutaneous treatment, at present, is the treatment of choice for both multiple or single splenic abscesses. This treatment is not used for the miliaric form because we believe that in this case, the most appropriate choice is intensive medical treatment, which if fails, may require splenectomy.

Abstract
Fibrovascular polyps of the oesophagus are rare tumor-like lesions characterized by development of the peduncolated intraluminal masses that can reach gigantic size and may have spectacular clinical presentation including regurgitation of a fleshy mass into the mouth and can lead to sudden death for occlusion of the larynx. Starting from a case observed and successfully treated by transoral resection we review the clinical radiographic and pathological findings of benign oesophageal tumor that requires surgical removal because of the progressive nature of the symptoms and the small, just known, risk of sudden death. The approach depends on the pedicule site.

Abstract
PURPOSE To compare the accuracy and reliability of objective and subjective refractions before and after laser in situ keratomileusis (LASIK) for myopia, hyperopia, and astigmatism. SETTING Augenchirurgie und Laserzentrum Hochrum, Innsbruck, Austria. METHODS In this prospective study, the objective refraction obtained with the Nidek AR-K 900 autorefractor was compared with the subjective refraction in 159 eyes (125 with myopia and 34 with hyperopia) operated on with 2 different lasers. Refractions were done before and 6 months after LASIK. RESULTS Preoperatively, the objective and subjective refractions correlated better in eyes with low myopia than in those with high myopia (P < .01). Postoperatively, objective refraction was less accurate and reliable than preoperatively. The difference between the objective and subjective spherical refractions was statistically significant (P < .0001) after LASIK in eyes with hyperopia. The correlation between the objective and subjective cylindrical refractions was stronger preoperatively. Especially after LASIK for hyperopia, the objective refraction did not reliably assess the magnitude and axis of the cylinder. The preoperative refractive error did not significantly affect the preoperative and postoperative difference between the objective and subjective refractions or the change between the preoperative and postoperative mean differences. The type of excimer laser used significantly affected the difference between the objective and subjective refractions. CONCLUSIONS Especially after LASIK for hyperopia, the objective refraction determined with the Nidek AR-K 900 autorefractor delivered erroneous results, which have implications for postoperative care and preoperative measurements for ocular surgery such as enhancement procedures or cataract surgery.

Abstract
PATIENTS AND METHODS In order to better define the potential advantages and risks of laser in situ keratomileusis (LASIK), we designed a prospective study including 73 eyes. RESULTS After 6 months, 62 eyes were examined. Myopia was corrected from -6.10 +/- 3.12 (mean +/- standard deviation) to +0.04 +/- 0.66 D, with 54 eyes (87.1%) being within +/- 1.00 D of emmetropia. Astigmatism was corrected from -1.07 +/- 1.02 to -0.32 +/- 0.89 D. Uncorrected visual acuity was 0.5 or better in 59 eyes (95.2%) and 1.0 or better in 27 eyes (43.5%) 6 months postoperatively. More than one line in best-corrected visual acuity was lost by 6 eyes (9.7%), with most of these eyes being highly myopic. There was no change or a gain in lines in best corrected visual acuity in 42 eyes (66.1%). Intraoperative complications arose in two eyes (2.7%); in one eye, visual acuity was temporarily decreased. More treatments were performed in 7 eyes (9.6%). Postoperatively, no haze, scars or central islands were detected. Patient satisfaction after LASIK was high: 97.3% were pleased or very pleased with the result. CONCLUSIONS In conclusion, LASIK is effective in the correction of myopia and myopic astigmatism. Although complications more frequently occurred in the correction of higher refractive errors, LASIK seems to be relatively safe compared with other refractive methods.

Abstract
PURPOSE To evaluate the precision and safety of myopia and astigmatism correction using laser in situ keratomileusis (LASIK). SETTING Augenchirurgie und Laserzentrum Hoch-Rum (Sanatorium der Kreuzsch-western), Innsbruck, Austria. METHODS In this prospective study, LASIK was performed on 66 eyes of 39 patients with myopia ranging from 1.50 to 16.00 diopters (D). Astigmatism, ranging from -0.00 to -3.00 D, was treated simultaneously. Surgery was performed with the Chiron Keracor 117 excimer laser and the Chiron Automated Corneal Shaper microkeratome. During the 6 month follow-up, manifest refraction as well as best corrected and uncorrected visual acuities were measured; corneal topographies were produced and slitlamp biomicroscopy was performed. Changes in visual acuity and corneal topography were evaluated. RESULTS After 6 months, mean myopia had decreased from 6.78 D +/- 3.48 (SD) to 0.40 +/- 0.98 D. Fifty-one of 63 eyes (81.0%) were within +/- 1.00 D of spherical emmetropia and 61 of 63 (96.8%) within +/- 1.00 D of cylindrical emmetropia. Uncorrected visual acuity improved in all eyes; it was 20/40 or better in 82.5% 6 months postoperatively. Best corrected visual acuity did not change in most eyes; 9.5% lost two or more Snellen lines. No central islands or corneal scars were detected postoperatively. Haze was noted in only 6 eyes (9.1%); it was transient and less than grade 1. No sight-threatening complications occurred intraoperatively. CONCLUSION Laser in situ keratomileusis was an exact and predictable procedure for correcting low, moderate, and high myopia and myopic astigmatism.

Abstract
This paper analyses daily ozone, cloud cover, solar radiation and broadband UV-B data for winter/spring at a low pollution Southern Hemispheric sub-tropical site (27.80 degrees S). The average ozone concentration for the period was 290 DU. An anti-correlation is presented between the ozone and UV-B data over a 5 day period during winter. An ozone deficiency of 45 DU was calculated for the cloud free day on the 16th July, 1995, in which the UV-B level exceeded the clear sky envelope by about 6%. Part of this increase may be attributed to a decrease in cloud cover. In winter, the July average of the daily integrated UV-B irradiance was 29.0 kJ/m2, (a level which is comparable to that observed in Japan during the summer months).

Abstract
The authors report the clinical and microbiological findings of a 6-month follow-up of nine AIDS patients affected with cryptococcosis. Among these, seven patients suffered from meningoencephalitis and two from disseminated infection. The antifungal therapy during acute illness included the administration of amphotericin B at doses of 0.6 mg kg-1 day-1 i.v. plus flucytosine at doses of 100 mg kg-1 day-1 i.v. during the first 15 days followed by itraconazole at doses of 400 mg day-1 p.o. in the following 15 days. The maintenance treatment included itraconazole at doses of 200 mg day-1 p.o. indefinitely. During the 6-month follow-up, one patient died of hepatic failure related to C virus (HCV) hepatitis reactivation and another patient died of polymicrobial pneumonia. In two patients, the presence of multiple nodular lesions in the cerebral computerized tomography (CT) scan, related to cryptococcal granulomas, was associated with the persistance of fungi in the cerebrospinal fluid. In three patients with meningoencephalitis the three-drugs regimen was effective in eradicating the neurological infection, and relapses were not observed during the maintenance therapy with itraconazole during the 6-month follow-up. The two patients with haematogenous cryptococcosis did not relapse after the 6-month follow-up.

Abstract
We present three patients who had laser in situ keratomileusis (LASIK) after corneal surgery as follow: 15 months after automated lamellar keratoplasty (ALK) for hyperopia, 6 months after ALK for hyperopia, and 2 years after penetrating keratoplasty (PKP). Although the first case was uneventful, intraoperative complications arose in the second case because the connection of the ALK-related flap to its stromal bed was insufficient. In the third case, the refractive error caused by PKP was corrected as shown by corneal topography and visual acuity measurement. In conclusion, LASIK after PKP can be considered a precise and safe procedure if 2 to 3 years pass between the procedures. An interval of 6 months between ALK and LASIK was too short, whereas 15 months after ALK for hyperopia, LASIK was performed without problems and delivered a good result.

Abstract
In the past 10 years, snowboarding has become a popular winter sport among young people, and the number of accidents has increased proportionately. The incidence of traumas from snowboarding is shown to be 4 to 6 for every 1000 medical examinations, which is similar to that of downhill skiing. However, other important statistical differences exist between the two sports. This study of 106 snowboarding-related injury cases analyzes the epidemiology of these injuries in Italy. Results found that 45.1% of injuries are located in the upper limbs and that significant advantages are obtained with the introduction of guards to protect the upper limbs during descent. Serious ligament injuries to the knee are more rare in snowboarding than in downhill skiing. In both sports, injuries are more common with rigid boots, which lead to a higher incidence of injury to the upper limbs. Finally, a high percentage of injury to beginners was found in this study. Training courses for those who are considering taking up the sport of snowboarding could significantly lower their risk of trauma.

Abstract
Cortical functions concerned with the execution of skilled movements can be studied through complex interactive tasks. Skilled performance task (SPT) offers the greatest deal of information about the electrophysiological components reflecting pre-programming, execution of the movement and control of the results. Overall, these components are indicated as "movement-related brain macropotentials' (MRBMs). Among them, Bereitschaftspotential (BP) reflects cerebral processes related to the preparation of movement and skilled performance positivity (SPP) reflects control processes on the result of performance. There is some evidence supporting a training effect on MRBMs, but less clear is whether long-term practice of a skilled activity could modify learning strategies of a new skilled task. We recorded MRBMs in subjects trained for a long time to perform a highly skillful athletic activity, i.e. gun shooting, and in a group of control subjects without any former experience in skilled motor activities. Our findings demonstrated the existence of a relationship between pre-programming and performance control, as suggested by decrease of BP amplitude and increase of SPP amplitude in presence of high levels of performance. Long-term practice seems to develop better control models on performance, that reduce the need of a high mental effort in pre-programming a skilled action.

Abstract
OBJECTIVE We evaluated findings on contrast-enhanced abdominal CT scans that suggest obstruction of the superior vena cava, brachiocephalic vein, or subclavian vein. SUBJECTS AND METHODS We conducted a retrospective review of 22 patients with superior vena caval, brachiocephalic vein, or subclavian vein obstruction and analyzed the upper abdominal images on a chest CT scan or an abdominal CT scan. We assessed collateral vessels in the upper abdomen to answer the following question: Did enhancement approach undiluted IV contrast or were there other findings? In the second part of our study, we conducted a prospective review of abdominal CT scans of 200 patients without known mediastinal disease or known upper extremity venous occlusion to determine the frequency of abnormal enhancement of these vessels in a healthy population. RESULTS The groups of collateral vessels revealed on abdominal CT scans were azygos or hemiazygos veins, internal mammary veins, lateral thoracic and superficial thoracoabdominal veins, vertebral venous plexus veins, and small mediastinal collateral veins. In the retrospective series, one patient had focal enhancement of the liver and early inferior vena caval enhancement due to collateral vessels. In the prospective series, abdominal CT scans of two patients (1%) revealed dense undiluted enhancement of one or more groups of collateral vessels: One patient had an ipsilateral pacemaker, and the other patient had an anterior neck phlegmon to the upper mediastinum. Both conditions may have been factors in the revealing of the collateral vessels. Two other patients (1%) in the prospective series had mild to moderate vessel enhancement that was less than that from undiluted contrast material. In one of these patients, the enhancement was related to abdominal wall hyperemia after surgery. In the other patient, enhancement may have been the result of ipsilateral axillary nodes. CONCLUSION On upper abdominal CT scans, dense undiluted contrast material in the collateral vessel groups that we studied suggests possible obstruction of the superior vena cava, brachiocephalic vein, or subclavian vein.

Abstract
BACKGROUND Nineteenth-century physicians working with cancer patients frequently reported that severe emotional losses and grief occurred in some cases before cancer. Research on psychoneuroimmunology seems to reactivate this interest and could give a possible convincing background. METHOD We recently observed the case of a 45-year-old woman who developed symptoms of breast cancer (ductal infiltrating carcinoma, T1, N1, M0) 3 years after the loss of her only child. The affection for the child compensated inadequacies of her marriage, which became increasingly unstable. The child died in a dramatic accident at home, while his mother was near him but unable to help. RESULTS The patient had a moderate genetic-familial risk of mammary cancer. Animal studies strongly suggest that stress, through neuroimmunomodulatory mediatory mechanisms, can significantly affect appearance and progression of mammary cancer. The patient developed long-lasting intense grief, despair and hopelessness. DISCUSSION We discuss the case from three main standpoints: genetic and risk factors for breast cancer; findings which demonstrated a relationship between stress, neuroimmunomodulation and cancer in animals; data from autopsy studies which found foci of latent breast cancer in 20% of healthy women in the same age range. Stress does not create cancer. However we hypothesize that in this case it could have contributed by the activation of a latent neoplasia and/or by impairing immunosurveillance during a critical life phase.

Abstract
In this study the authors evaluate the relationship existing between reduced glutathione (GSH) and increased indexes of muscle performance. GSH has a protective action on the cell either against the oxidative stress or for its ability of removing through out the body xenobiotic substances circulating. 15 male competitive pentathlon athletes were the sample of this research. The aim of the research is to evaluate the possible role of GSH to determine the anaerobic threshold through its blotting function.

Abstract
A study of 288 cases was made of those registered blind and partially sighted patients in Lothian Health Board area. The purpose of this study was to identify the trend of the main cause of visual handicap in a general population. The registration rates were analysed by age, sex and causes. It was found that the leading causes for blindness were age-related macular degeneration (ARMD) (58.8%), chronic open angle glaucoma (COAG) (12.8%), proliferative diabetic retinopathy (PDR) (4.9%), while for partial sight (PS) the main causes were age-related macular degeneration (ARMD) (57.1%), chronic open angle glaucoma (COAG) (8.8%) and congenital (4.7%). For both men and women the incidence rate of blindness remains low until the age of 65, followed by a considerable increase, especially after the age of 75. The male to female ratio for blindness was 1:2.06 and for partial sight 1:2.58.

Abstract
The pharmacokinetics, tolerability, and efficacy of carbamazepine (CBZ) and the pharmacokinetics of carbamazepine-10, 11-epoxide (CBZE) were studied after chronic administration of a conventional tablet formation or of the controlled-release (CR) formulation of CBZ 400 mg (Tegretol 400) to 20 patients with epilepsy treated with carbamazepine and complaining of intermittent adverse effects. To compare the two formulations at the same doses and dose schedules, the study design had to be open, within-patient, with an initial 4 week period to individually adjust the dosage schedule with conventional CBZ followed by a 4 week period in which the CR formulation was substituted for conventional CBZ at the same daily dose and given by the same schedule. A further 4 week period was also studied to evaluate the same dosage of the CR formulation but given b.i.d. In this latter period six patients required an increase in dosage (200 mg/day). Before the beginning of the study and at the end of each period seizure frequency and tolerability were assessed. Tolerability was estimated with a specifically prepared scale that assesses the main items and with an overall rating scale. At the end of each treatment period, serum levels of CBZ and CBZE were determined at various times over a 10 h period. Peak plasma concentrations (Cmax) of CBZ and the fluctuation index (FI) were significantly lower for the CR CBZ, although minimal and mean plasma concentrations were the same in the three periods of the study.(ABSTRACT TRUNCATED AT 250 WORDS)

Abstract
Severe ventricular dysfunction in a patient prevented weaning from cardiopulmonary bypass after myocardial revascularization. Calcium chloride and increasing doses of dopamine had no effect. Coronary vasospasm was diagnosed based on ST elevation and myocardial failure. Verapamil 0.5 mg, injected into the aortic root, was followed by a dramatic improvement in cardiac contractility and successful weaning from cardiopulmonary bypass without inotropic support.

Abstract
Gastrointestinal cancers are very scarce for the people under twenties. Such a rarity, as misguides diagnostic trend, is responsible, in the greater part of cases, of the lag in the recognizing these neoplasm and, consequently, reduces the expectations of surviving whether medium or long term. Authors report their experience as regards to observation of two cases of malignant neoplasm of the stomach and of the recto-sigmoid joint in young patients of fourteen and nineteen years old and they emphasize the importance of a complete diagnostic route which, in spite of age, does not exclude the possibility of a neoplastic pathology in the presence of suggestive persistent symptomatology. It is underlined the importance of early diagnosis in fact survival yield is always and however dependent on a disease stage and not on age. Furthermore it is underlined that the young patient is subject to a rate of postoperative complications which is marginal compared with intervention yield, this is translated in a better responsiveness of young patient to radical and, if it is necessary, extended interventions.

Abstract
The recent development of improved production techniques for bispecific monoclonal antibodies (biMAbs) has significantly increased interest in specific purification procedures. In this investigation, a general high-performance liquid chromatographic (HPLC) purification method is proposed that allows highly purified biMAbs to be obtained from mouse ascites fluid containing a mixture of different antibodies, i.e., parental MAbs, active biMAb and a mixture of randomly assembled heavy and light chains. Proteins from ascites fluid were precipitated with ammonium sulphate and applied to a high-performance protein A column to separate the total immunoglobulin fraction. BiMAbs were isolated from other immunoglobulins by two subsequent passages through a high-performance hydroxyapatite (HPHT) column. This purification protocol combines specificity of protein A for immunoglobulin G (IgG) and high selectivity of hydroxyapatite for different IgG idiotypes. All purification steps were performed rapidly and reliably by HPLC. This method was applied to the purification of six different biMAbs with consistently high yields, purity and homogeneity. This general purification method may prove extremely valuable when highly pure preparation of biMAbs is required, as for in vivo use.

Abstract
A 25-year-old male drug addict presented with a rapidly progressive ascending tetraplegia, requiring assisted ventilation. One month earlier he had fever (40 degrees C) and asthenia. Cerebrospinal fluid (CSF) examination showed elevated albumin level and albuminocytologic dissociation. HIV testing was positive in both serum and CSF. Plasma exchange therapy only partially improved the symptomatology. After five months the patient remained with a moderate tetraparesis. Differences between this and other cases of Guillain-Barré syndrome in HIV-seropositive patients reported in the literature are discussed.

Abstract
Monoclonal antibodies (MAbs) have been prepared with specificity for diethylenetriaminopentaacetic acid (DTPA) used to chelate metal radioisotopes to immunoglobulins for radioimmunoimaging and radioimmunotherapy. The use of fusion partners of lymph node-derived B cells resulted more frequently in the isolation of IgG secreting hybridomas than with splenocytes. All MAbs have been selected for simultaneous recognition of chelated and unchelated DTPA, and have been characterized in their biochemical, physico-chemical and immunochemical features. In view of the potential use in development of bifunctional MAb, these novel MAbs were also proven to lack detectable cross-reactivity with normal human tissues.

Abstract
Because of the growing incidence of neurological disorders in HIV-infected patients, an early detection of the disease seems to be of paramount importance, especially in asymptomatic subjects. By using electroencephalography coupled with computerized spectral analysis and "mapping" (EEG-CSA), paroxysmal sharp activity was detected in 26 patients belonging to different stages of HIV infection. Seven of them (27%) were also symptomatic, (table; see text) showing signs of convulsant disease. The presence of focal or generalized paroxysmal activity, often associated with seizures, might suggest an early localization of HIV in cortical structures.

Abstract
One hundred and one subjects, with various degrees of HIV infection, were enrolled in a longitudinal study aimed at evaluating the correlation between clinical and instrumental findings in the development of HIV-related subacute encephalitis. The method used was electroencephalography coupled with computerized spectral analysis (EEG-CSA) and mapping. The findings recorded by this method were compared with those obtained by computed tomography (CT) scan and neurological examination. The EEG-CSA findings were divided into four categories according to their severity. EEG-CSA was shown to be very sensitive in detecting the first signs of a forthcoming neurological disease. Following 11 months of observation, 22 out of 40 (55%) neurologically asymptomatic individuals who, at the beginning of the study showed some EEG-CSA abnormalities, had clinical evidence of a subacute encephalitis whereas only two out of 37 (5.4%) subjects who were previously free of EEG-CSA abnormalities had some signs of neurological disease (P less than 0.001) after the same period. Of those remaining who were already symptomatic when the study started, the neurological progression of HIV infection was also monitored by EEG-CSA.

Abstract
Of subjects with asymptomatic HIV infection or Lymphoadenopathy Syndrome, 185 were studied by means of electroencephalography coupled with computerized spectral analysis and mapping (EEG-CSA). Abnormal EEGs were found in 30 of 118 (25.4%) patients with asymptomatic infection (CDC Group II) and in 20 of 67 (29.9%) patients with Lymphoadenopathy Syndrome (CDC Group III). The most common EEG abnormalities were represented by theta slowing on the frontal and fronto-temporal lobes and, in some cases, by delta slowing and paroxysmal sharp activity on the forebrain. Among 50 patients with abnormal EEGs, 16 showed some abnormalities on neuropsychological testing, whereas mild signs of cerebral atrophy were evident on CT scan in only 12 patients. These findings suggest that EEG-CSA could be a useful and sensitive method in the early detection and monitoring of HIV-related subacute encephalitis.

Abstract
This study reports the results obtained by an Electroencephalographic screening of 450 HIV-seropositive patients, belonging to different stages of infection. The major bioelectrical changes of cerebral activity were evident in AIDS group (87.2%) and in ARC group (64.5%), whereas mild abnormalities were present in LAS group (38.8%) and in asymptomatic infection (19.2%), often without any evidence of neuropsychological impairment. Therefore, we emphasize the usefulness and the sensibility of Electroencephalography and, in particular, of Electroencephalography coupled with Computerized Spectral Analysis with the aim of identifying the subclinical stages of AIDS Dementia Complex.

Abstract
Intra-ocular pressure (IOP) was measured immediately after normal subjects were woken from at least 5 hours sleep. Measurements were made at approximately 15 s intervals, for about 20 minutes. The IOP of all 14 subjects was elevated after sleep and returned to baseline levels with a time course which was approximately exponential; the longest time constant of return of IOP to baseline was 1056.9 s, and the shortest 133.5 s. Mean time constant of recovery was 404.8 s. The decrease in IOP may be related to melatonin levels which increase during sleep and decrease in the light, or be related to accommodation and eye movements which may act to 'pump' aqueous from the eye.

480 cases of advanced gastric carcinoma are classified according to Laurén or WHO and correlated to age and sex of the patients. The modal value of the incidence for age of the mucinous histologic type is 61-65 years for the men and 71-75 years for the women, while in the signet ring cell histologic type is 50 years in both sexes. These relationship, obtained only by the WHO classification, suggest that mucinous and signet ring cell type constitute distinct histoepidemiological entities.

Abstract
The Authors report a case of a 49 year old female patient with Gardner's Syndrome and adenocarcinoma of the Ampulla of Vater. In this case, adenocarcinoma of the Ampulla of Vater was associated with duodenal polyp (adenoma), which suggests that adenocarcinoma is the consequence of malignant of duodenal polyps. The world medical literature was reviewed and 29 cases of periampullary carcinoma complicating familial polyposis or Gardner's Syndrome were analyzed.

Abstract
In patients with coronary artery disease, left ventricular (LV) regional wall akinesia can develop during the Mueller maneuver. The present study determines if the presence of myocardial ischemic disease with no infarction is a sufficient condition for this to occur, or if the presence of prior acute myocardial infarction (MI) is necessary. In men, first-pass radionuclide ventriculography was performed in the 30 degree left anterior oblique supine position to measure LV ejection fraction, end-diastolic and end-systolic volumes and heart rate, and to obtain an image of the LV cavitary perimeter. This procedure was performed in 4 subject groups: 13 normal volunteers, 25 patients with coronary artery disease but no prior MI, 13 patients with coronary artery disease and prior nontransmural MI, and 36 patients with coronary artery disease and prior transmural MI. All patients had angina and underwent routine contrast coronary angiography; 60 also underwent contrast coronary angiography; 60 also underwent contrast LV angiography. Ejection fraction decreased during the Mueller maneuver in each of all the coronary artery disease groups (p less than 0.01), but not in the normal subjects. Heart rate increased in groups 1, 2 and 4 (p less than 0.01), and end-diastolic volume decreased in all 4 groups (p less than 0.01), whereas end-systolic volume did not change. Only in group 4 did regional wall akinesia develop (17 patients) during the Mueller maneuver. Among patients who had akinesia during the Mueller maneuver and also underwent routine contrast ventriculography, half of the akinetic segments were not seen on routine contrast study, but were seen only on radionuclide ventriculography during the Mueller maneuver.(ABSTRACT TRUNCATED AT 250 WORDS)
