Geriatric patients are preferentially involved in ischemic bowel disease. The sudden occlusion of the large mesenteric arteries (a. mesenterica superior (more frequently) and inferior) is followed by intestinal gangrene and peritonitis with a poor prognosis and a high letality (greater than 90%). In chronic intestinal ischemia the leading clinical symptom is postprandial pain ('claudicatio intestinalis'). In some cases of acute mesenteric artery occlusion no embolus or thrombus will be found. In these cases the circulation in the arteriosclerotic vessels falls below a critical value due to cardiac insufficiency, shock, digitalis overdose and others. In less severe ischemia the mucosa is involved being most sensitive to O2 deprivation. It usually regenerates within a few days. This form is found more frequently in the colon than in other parts of the gut (about 40%): ischemic colitis. The therapy - if possible in acute, fulminant ischemia or if necessary in chronic intestinal ischemia - is surgical consisting in reconstructive procedures of the mesenteric circulation.

A case of meningeal carcinomatosis associated with cerebral metastases from an adrenal neuroblastoma is described. The clinical picture was ushered-in by bilateral sciatic pain in a 50 years old female and was followed by rapidly progressive sensory-motor deficits of the arms and legs, leading to flaccid quadriplegia associated with paralysis of cranial nerves and episodes of mental confusion. Death occurred 4 months alter, in cardiac failure. At autopsy, a bilateral tumor of the adrenal glands was found. No metastases were detected anywhere except in the central nervous system. Histology identified the tumor as a neuroblastoma; meningeal carcinomatosis, radicular infiltration by tumor cells and parenchimal metastases were found in the central nervous system. Neuroblastoma is typically a tumor of childhood, only 13% of them being found in adult's according to Russell and Rubinstein. Meningeal metastases from adrenal neuroblastoma have not hitherto been reported in the literature. In our opinion, the most likely mode of spread of tumor cells to the central nervous system was hematogenous because of the presence of small multiple intraparenchimal metastases; however, possible spread through the perineural lymphatics, as proposed by others, cannot be excluded, due to the prominent localization of tumor cells at spinal roots level. The main differential diagnostic problems (paraneoplastic neuropathy (Wyburn-Mason) and infectious subacute or chronic meningitis) are discussed. The authors stress the emportance of complete cerebro-spinal fluid examination including a careful search for tumor cells.

A man, aged 63, had an illness which lasted 11 months from onset with pain under the left costal margin which radiated to the epigastrium, until his death from cardiac failure. His symptoms consisted principally of parasthesias and proximal weakness of both upper and lower extremities with atrophy of the shoulder and pelvic girdles. He developed pyramidal tract signs, became euphoric, emotionally unstable and mentally retarded. There was no clinical evidence of cerebellar dysfunction. Bronchogenic carcinoma was suspected from a tomograph of the thorax, but, in spite of extensive clinical and laboratory studies, the diagnosis was verified only postmortem. The CSF cell count was high at first but diminished as the disease progressed. Muscle biopsies revealed chronic generalized denervation without signs of myopathy. Neuropathologically, encephalomyeloradiculoneuritis concentrated on the spinal cord was combined with severe rarefaction of the ganglion cells of the anterior horns and with bilateral degeneration of the lateral pyramidal spinocerebellar and posterior tracts. A more diffuse process was obvious in the anterolateral tracts of the lumbar region. Polyneuropathy concentrated in the distal region was accompanied by slight inflammatory reaction in the sciatic nerve. Cerebellocortical degeneration which exceeded physiological age-related rarefaction was also present. The findings are discussed in relation to the literature.

Of all aortic dissections, 10% are chronic. Typically they arise distal to the left subclavian artery and have reentry points into the true lumen. Pain may be minimal or absent and patients often present with cardiac failure. Chronic dissections are more likely to appear radiographically as atherosclerotic aneurysms on a chest film than are acute dissections. Four cases of chronic dissections found incidentally during angiography are presented.

A study of 55 patients with heart disease suspected of being viral in origin was carried out a Medical College Hospital, Nagpur, over a period of 2 years. Virus studies as well as other routine tests were carried out on all patients. In 19 patients a virus aetiology of the heart disease was proved by isolation of one of the subtypes of Coxsackie B virus and/or on the basis of fourfold rise in neutralizing antibody titre in paired sera. Of these patients, 5 had acute myocarditis and 5 had acute myopericarditis; 3 had acute pericarditis; 3 had congestive cardiac failure of obscure aetiology; 2 had pleuropericarditis, and the remaining 1 developed post-partum heart failure with cardiogenic shock. All had electrocardiographic abnormalities. Thirteen had cardiomegaly; 1 had a right-sided pleural effusion and 2 had pericardial effusion. Virus could not be isolated from pericardial fluid or pleural fluid in these 3 patients. Follow-up studies up to 10 weeks from discharge revealed that 8 patients were clinically normal but 4 of these 8 had persisting ST-T wave changes, and in 4 the electrocardiogram had returned to normal. Of the remaining 11 patients, 3 had persistent chronic heart failure, 3 had vague symptoms of praecordial pain but no abnormal signs, and 5 patients were lost to follow-up.

There are probably 2.5 million patients with Paget's disease in the U.S.; 125,000 of these have severe disease meriting specific treatment. While the diagnosis can often be made by inspection, or by measurement of the temperature of involved limbs, it is often missed. Nonspecific findings include pain, headaches, deafness, heart failure, neurologic deficits and renal stones. A specific diagnosis can usually be established by radiologic examination of the skeleton and measurement of the serum alkaline phosphatase level. Bone scans are often helpful. In moderate-to-severe symptomatic disease, calcitonin limits the unregulated chaotic bone resorption and exerts highly specific and effective suppressive activity.

In cardiac failure unresponsive to digoxin and diuretics, afterload reduction brings about a dramatic increase in cardiac output, renal perfusion and responsiveness to diuretics; furthermore, the decrease in venous pressure relieves the dyspnoea. Intravenous vasodilators should only be used when sophisticated haemodynamic monitoring equipment and experienced physicians are at hand. Indications for the use of these agents are severe cardiac failure, acute myocardial infarction complicated by left ventricular failure, persistent ischaemic pain and limitation of infarct size. A wide variety of oral vasodilator agents is available, all having different sites of action; the choice of vasodilator agents should be tailored to the needs of the patient. Treatment with these agents is indicated in patients in whom cardiac failure becomes refractory to conventional therapy with digoxin and diuretics. The utmost care must be taken to avoid further impairment of cardiac output by excessive reduction of the left ventricular end-diastolic pressure (LVEDP) and hypotension, which will jeopardize myocardial, renal and cerebral perfusion.

Twenty-one patients with postinfarction angina (2 to 15 days after acute myocardial infarction) unresponsive to medical therapy were treated by intra-aortic balloon pumping (IABP). Anginal pain and electrocardiographic (ECG) ST-segment changes were prevented in all patients. Coronary angiograms were obtained during IABP without complication and confirmed severe coronary artery disease. Of the four nonoperated patients, three had reinfarction and two died of cardiogenic shock. Seventeen patients underwent aorta-coronary bypass grafting, associated with aneurysmectomy in two patients and closure of a ventricular septal defect in one. Sixteen patients survived the operation. All survivors are in clinically improved condition and 14 are pain free from 9 to 28 months postoperatively, but three have mild heart failure.

The role of arterial counterpulsation was sought in 100 patients with severe refractory cardiac failure complicating myocardial infarction. Seventy-four were in shock and 26 were not. Average duration of counterpulsation was 7.0 days. Hospital survival was 34 per cent (25/74) in shock (predicted less than 10%) and 65 per cent in patients who were not in shock (predicted less than 50%). Survival at 4 years was 10 +/- 4 per cent in shock and 37 +/- 11 per cent in patients not in shock; functional status was class 1 or 2 in 5 of 9 patients in shock and in 8 of 12 survivors not in shock. Results were best when counterpulsation was started early after onset of symptoms, when ischaemic pain was still present, or when a mechanical defect was corrected surgically. Early coronary artery bypass surgery performed alone in 9 patients did not influence survival or functional status. Complications of counterpulsation occurred in 17 patients in shock and in 2 patients not in shock, all but 6 on the first day; none directly caused death. Counterpulsation is an effective and safe adjunct to medical treatment of complicated infarction provided the intervention is prompt.

1. Coronary insufficiency is a pathophysiologic state that can initiate lethal cardiac arrhythmias in the absence of myocardial necrosis. Patients with suspected coronary insufficiency should be monitored until they are stabilized and a diagnosis is confirmed. 2. Early and adequate intravenous antiarrhythmic prophylaxis with lidocaine to raise the fibrillation threshold in the setting of coronary insufficiency can prevent primary ventricular fibrillation. Classic "warning arrhythmias" are not predictive of ventricular fibrillation. Their persistence during adequate antifibrillatory prophylaxis does not indicate therapeutic failure. 3. The isoenzyme of creatine phosphokinase, CPK-MB, is an extremely sensitive and specific indicator of myocardial necrosis if measured serially during the 24 hours following the onset of symptoms suggesting coronary insufficiency. It may prove most useful in eliminating the false positive diagnosis of myocardial infarction in difficult clinical cases. 4. The management of heart failure in myocardial infarction requires an understanding of the relationship between ventricular preload and the cardiac output. The treatment of clinical manifestations of an elevated ventricular preload in asymptomatic patients is not justified and may be detrimental. In symptomatic patients, however, judicious manipulation of ventricular preload should be the first therapeutic consideration, and an optimal filling pressure should be achieved and maintained when other determinants of the cardiac output are manipulated. 5. Indications for the prophylactic insertion of a temporary transvenous pacing electrode for heart block associated with myocardial infarction must be individualized. Most authorities agree that prophylactic pacing may be justified in patients with evidence of new infranodal block involving two of the three fascicles. Patients with bifascicular block who progress to complete heart block transiently may benefit from permanent transvenous pacemaker insertion before discharge. 6. Hospitalized patients with persistent pain of suspected cardiac origin but without evidence of myocardial infarction can be studied safely with coronary angiography. A small percentage will be normal or have diffuse disease that is inoperable. Of those with operable disease, short-term mortality appears to be similar for medical and surgical therapy. 7. Patients with an uncomplicated myocardial infarction may be safely discharged from thehospital by day 7-10. 8. Experimental evidence indicates that modification of infarct size is possible. Application of these concepts to human subjects presently is limited by the absence of a proved method of measuring infarct size in vivo in humans.
