Circumferential dissection of the ascending aorta with intimal intussusception. Case report and review of the literature.

The present report describes an unusual case (apparently the 10th in the world literature) of a type-A aortic dissection with full circumferential detachment of the ascending aortic intima and intussusception thereof into the aortic arch and descending aorta, partly occluding the arch vessels. Computed tomographic scanning and 2-dimensional echocardiography failed to detect an intimal flap and a false lumen in the ascending aorta. Aortic dissection was visualized by aortography. The ascending aorta was surgically repaired and the aortic valve resuspended. The pertinent literature is reviewed.

[The use of a total parenteral nutrition solution in major gastrointestinal surgery].

This study evaluates the efficacy and tolerance of a complete preparation for TPN, "Trive 1000" consisting of an emulsion of lipids, amino acids and sorbitol, balanced in the substratum with a caloric water ratio of 1 cal/1 ml. The preparation offers sterility and simplicities of use guarantee. 20 patients, subjected to major digestive surgery, were treated. The valuation of the product has been effected through nourishing index of common use and by checking of side effects. The results confirm the handling and the tolerance of "Trive 1000" although in hepatic and nephropathic patients the solution must be used with caution.

[Endoscopic and pharmacologic treatment with omeprazole of upper digestive hemorrhage].

Upper gastrointestinal bleeding is still a subject much discussed as much for the diagnostic approach and as by the therapeutic decisions read. The authors present their experience of the treatment of upper gastrointestinal bleeding not caused by portal hypertension or by neoplasm. The patients undergo emergency endoscopy by haemostatic treatment if necessary and pharmacological therapy by omeprazole. The evaluation criteria are: stopped bleeding, the need of blood transfusion, the healing of the bleeding site. Stopped bleeding has been watched at first endoscopic check in 85% of patients; only 26 blood units has been necessary; the complete healing of bleeding injury happened not later than 30 days.

[Acute enterorrhagia. A diagnostic-therapeutic approach].

The Authors report their experience in cases of severe lower intestinal bleeding. On the basis of personal data and previously reported results, endoscopy is shown to be the primary and sometimes essential method, especially in the case of colo-rectal bleeding, both in terms of its diagnostic precision and possible therapeutic uses. This technique was used to treat all emergency cases, obtaining a diagnostic resolution in 85.6% and hemostasis and/or the concomitant removal of the lesion in 52.3% of cases.

Prophylaxis of infection with intravenous immunoglobulins plus antibiotic for patients at risk for sepsis undergoing surgery for colorectal cancer: results of a randomized, multicenter clinical trial.

BACKGROUND: The results of a randomized, multicenter clinical trial with perioperative short-term antibiotic plus intravenous immunoglobulins (IVIG + A) versus antibiotic alone (A) for prevention of postoperative infections in patients at risk for sepsis undergoing surgery for colorectal cancer are presented. METHODS: The patients at risk for sepsis were selected by an original multiparametric test based on delayed-hypersensitivity skin testing and serum protein electrophoretic subfractions. This screening had shown 76% positive predictability in a previous validation assessment. Eighty patients at risk for sepsis were selected prospectively from 210 patients undergoing surgery for colorectal cancer; 43 patients were randomly assigned to the IVIG + A group and 37 to the A group. IVIG was administered on the day before operation, on the first and fifth postoperative days. RESULTS: There was a clear-cut reduction of postoperative infections in the IVIG + A group: 21 infections in 20 patients versus 37 infections in 29 patients in the A group (p less than 0.004). With regard to serum immunoglobulin (Ig) G monitoring, basal IgG levels were significantly lower in patients given IVIG + A who had postsurgical infections (p less than 0.005) compared with patients with a regular outcome, whereas the same was not true in the A group of patients. CONCLUSIONS: A significant decrease (p less than 0.001) of postoperative IgG was evidenced in the A group of patients who had infections as opposed to a significant increase (p less than 0.001) of postoperative IgG in IVIG + A patients with a normal outcome.

Scinticisternography in presenile and senile degenerative disease.

86 patients suffering from various senile and presenile degenerative diseases were studied using scinticisternography with In111-DTPA. Flow reversal and delayed clearance were observed in 62 of these patients. These alterations, possibly related to the cerebrospinal fluid dynamics, show the aspecificity of the SC picture. The SC picture does not seem to be correlated to the clinical signs.

Spinal cord softenings of identifiable cause: anatomical and clinical features.

To complete our bibliographic review of spinal cord softenings, we now discuss the clinical and pathological findings in the cases of known or probable cause. Comparison of the diagnostic groups yields some differences in respect of sex, age and mode of onset, survival and extent of the anatomical lesion. Further differences, especially in age at onset, clinical pattern and lesion site, emerge from a comparison of these cases of known or probable cause with those whose cause is not apparent.

Recurrent vascular myelopathy. Report of a case with autopsy.

A case of ischemic myelopathy which was marked by two clinical episodes, separated by a 4-month interval and affecting the same level of the spinal cord, is reported. A wide-ranging search through the literature shows that the recurrent type of ischemic vascular myelopathy is very rare.

Some little-known aspects of spinal cord softening.

311 cases of spinal cord softening, were selected for review. The following points emerged from this study: 1) spinal cord softening is a rare occurrence; 2) while formerly syphilis was the most frequent cause, recently reports of cases secondary to aortic disease or to embolism with diffuse signs of arteriosclerosis and circulatory failure pointing to a different pathogenesis have become more frequent; 3) the site of softening rarely corresponds to the vascular spinal territories as defined by the anatomists, from which it may be argued that often several arterial territories may be involved simultaneously or, alternatively, that the arterial territories are not so rigidly defined as anatomical research has led us to suppose; 4) the few cases of multiple vascular lesions show that, as happens in the brain, the cord may be damaged contemporaneously or successively in several areas.

Roving lateral eye movements in coma. A clinical-pathological study.

Five patients in deep coma due to extensive supratentorial lesions presented roving lateral eye movements (ping-pong gaze), distinguished by the fact that the eyes, after moving to one extreme of gaze, returned to the midline instead of to the opposite extreme. The phenomenon was reported recently by Reynard et al.
