[The results of large clinical trials comparing primary angioplasty and thrombolysis].

One of the main cardiological debate is about which one, between primary angioplasty (PTCA) and thrombolysis, is to prefer for the therapy of acute myocardial infarction. The data available in the literature do not show that one of these two therapeutical choices is definitely better than the other one. Since the main therapeutical goal in patients with acute myocardial infarction is the early and persisting recovery of the anterograde coronary flow, the best therapy for every patient is the one that can be performed more quickly and safely. Therefore, PTCA has to be preferred whenever it can be done quickly, by expert personnel and with cardiosurgical support, especially in patients considered to be at high risk or with contraindications to thrombolysis. Otherwise, thrombolytic therapy should be better. Stent implantation seems to be better than conventional angioplasty, in particular for the reduction of restenosis and reocclusion. These conclusions, however, derive from small studies and require further evidences. Moreover, there are not trials directly comparing primary PTCA and stent implantation with thrombolysis. Rescue PTCA, after failure of thrombolytic therapy, is useful when the coronary flow of the culprit lesion is TIMI 0 or 1, but not when the flow is TIMI 2; there are neither indications to early, but not rescue, angioplasty in all the patients already thrombolyzed. Finally, for patients with acute myocardial infarction and cardiogenic shock, the data currently available, derived more from observational than from randomized studies, suggest revascularization by PTCA.

[Chronic viral hepatitis: diagnosis and treatment].

HBV and HCV cause most of chronic hepatitis; the HDV is a co-infectious virus and it rend the help of HBV to duplicate; HAV and HEV do not induce chronic hepatitis. Etiology is not the same, without apparent reasons, in all the world and the distinction between persistent chronic hepatitis and active idiopathic chronic hepatitis is meaningless, because one can shift in the other. Diagnosis is possible using serologic tests and by determination of the DNA of the HBV and RNA of the HCV. Interferon is a good therapeutic tool either for B hepatitis than for C hepatitis in about 50% of case. On the contrary, the results obtained with liver transplantation are disappointing and those achieved with ribavirin have not been conclusive yet. The treatment with INF for more than one year and with full dosages, gives good results in about 50% of patients with hepatitis D. In the other patients it is not useful a second cycle with INF or the introduction of pure antiviral drugs alone or in association with INF.

[Intrahepatic cholestasis].

The intrahepatic cholestasis is not an common syndrome, in particular way in people between 50 and 60 years of age. It is often unknown or confused, because of itching, with allergic or dermatologic diseases. The most frequent causes of intrahepatic cholestasis are primary sclerosing cholestasis, primary biliary cirrhosis and hepatic cirrhosis. The pathogenetic mechanism is the faulty secretion of bile and, more bile salts. The diagnosis is allowed by anamnesis, objective examination and, above all, biochemical markers of cholestasis, echography, TC, NMR and liver biopsy. Therapy consist of generic (hypolipidic diet, liposoluble vitamin and others) and specific (UDCA, SAMe) measures.

[Infective endocarditis].

The authors underline the recent increase in the incidence of infective endocarditis (IE) involving the right side of the heart, because of instrumental procedures and, above all drug-addiction. They describe the epidemiology, congenital and acquired predisposing heart diseases, the most common portals of entry of the infective agents, etiology, pathogenesis, pathology, cardiac and extracardiac clinical manifestations and complications, clinical and instrumental diagnosis, medical and surgical therapy, prognosis and prevention of disease.

[Paget's disease].

The authors have observed several cases of Paget's disease in their Centre for the Study, Diagnosis and Therapy of Osteoporosis. They define this disease and describe the probable etiology by Paramyxoviruses, the macro- and microscopic anatomopathological changes, the clinical manifestations, the complications (that are sometimes deadly: sarcoma), the diagnostic resources and, finally, the latest therapeutic possibilities (combined calcitonin and diphosphonate) that are useful only in patients with pain or complications.

[Orthostatic hypotension in the aged].

The authors consider the remarkable incidence and the important consequences of orthostatic hypotension in the elderly. They underline the etiologic importance of primary and secondary alterations of the autonomic nervous system and other concomitant causes. They illustrate the pathophysiologic mechanisms and specify how to arrive at the correct diagnosis. Finally they recommend to use drugs only after the failure of behavioral and physiatric measures.

[The cardiovascular system and antidepressive drugs].

The authors consider the ever-increasing number of depressed patients, related to the stress of modern life and to the prolongation of life span. They stress that these patients are often cardiopathic or impaired by the senile heart. Finally they illustrate the cardiovascular effects of antidepressant drugs and how to avoid them.

[Aneurysm of the abdominal aorta. Description of a case].

Having recalled the insidious onset, etiopathogenesis, incidence, clinical and instrumental diagnosis, and the very severe prognosis of abdominal aortic aneurysm, as well as the excellent results obtained by elective surgery, the authors describe a case they had occasion to observe and in which sudden rupture of the aneurysm was fatal.

[Cardiac risk in noncardiac surgery].

After recalling cardiac disorders and the cardiac risk of non cardiac surgery, the authors illustrate the methods for evaluating clinical risk in individual patients, the instrumental procedures appropriate for the diagnosis of ventricular dysfunction or myocardial ischemia which are responsible for the majority of cardiac complications during surgery. Finally, they describe alternative therapies for high-risk patients.

[Sacrococcygeal chordoma. A case report].

The authors describe the diagnosis of a rare neoplasm, a sacrococcygeal chordoma, which was suspected in view of compressive symptoms and diagnosed with the aid of endoscopic and x-ray methods (barium enema and CT). Diagnosis was confirmed at surgery.

[Tuberculosis: a disease that is difficult to eradicate. Description of a case].

The authors stress the recent increase of tuberculosis, especially in high-risk areas and populations. They illustrate the changes the disease has undergone lately, also with reference to a case they had occasion to observe. They describe 9-month and 6-month treatment schemes as well as the drugs that can be applied in cases of drug resistance which is rather frequent in AIDS patients.

[Carcinoma of the pancreas and description of 5 cases].

Having reviewed the frequency of pancreatic cancer, its symptomatological insidiosity, the risk factors, the present excellent diagnostic possibilities, the surgical techniques, which are unfortunately radical only in 30% of the cases, the potentialities related to the recent discovery of sex-hormone receptors in the tumor, the authors underline the necessity of an early diagnosis, considering carefully the vague, but precious, initial symptoms.

[Osteoporosis: a silent thief].

Having stressed the often disregarded social importance of osteoporosis and listed the risk factors, the authors illustrate the classification, etiopathogenesis, paucity of symptoms and the most valuable diagnostic resources, and discuss present therapeutic possibilities, while stressing the fact that, as in many other situations, prevention remains the best policy.
