A 31-year-old male patient with type Ia glycogen storage disease was admitted to our department complaining of general fatigue and right hypochondriac pain. He exhibited massive hepatomegaly with systemic hypoglycemia, lactic acidosis, hyperuricemia, hyperpyruvatemia and hyperlipemia. The failure of blood glucose levels to increase after a glucagon loading test, and a reduced lactate level on glucose tolerance test were also observed. Various imaging techniques suggested hepatic adenoma with hemorrhage in the tumor, which was confirmed histologically. There was a complete absence of glucose 6-phosphatase activity, as determined by an enzyme assay on resected liver specimens, which proved the case to be type Ia glycogen storage disease. We also reviewed all previously reported cases of hepatic tumor and glycogen storage diseases. We conclude that, since hepatic adenoma is not rare in this disease, and is complicated by hemorrhage, rupture and malignancy, careful follow-ups are necessary.

Although Virchow postulated 100 years ago that hypercoagulability states exist, it has only been in recent years that methods of documenting hypercoagulability have been developed. These clotting tendencies can be acquired or congenital. The common causes of acquired clotting tendencies include conditions which result in tissue and cellular damage, shock, transfusion reactions, and tissue necrosis. Certain drugs and drug reactions, and certain disease states which include blood dyscrasias and cancer are also associated with clotting problems. In certain diseases such as homocystinuria, hyperlipidemia, and lupus erythematosus, abnormal clotting tendencies may also develop. Important advances in the recognition of hypercoagulability have come with the documentation that congenital clotting abnormalities exist. Moreover, these abnormalities are proving to be more common than are congenital bleeding syndromes. Patients who appear to have spontaneous clotting manifestations and are under 40 years of age should be screened for one of these abnormalities. These congenital clotting tendencies can be classified as defects in thrombosis inhibitors, dysfibrinogenemias, or defects in fibrinolysis. The first thrombotic inhibitor defect recognized was antithrombin III deficiency which was reported in 1965. Subsequently, Protein C, Protein S, and Heparin cofactor II deficiencies have been recognized as contributing to thrombotic tendencies. Dysfibrinogenemias are relatively rare and most are associated with bleeding problems; however, 11% of the abnormal fibrinogens are associated with a clotting tendency. The reason appears to be that these fibrins are resistant to fibrinolysis. The most common defects which are associated with thrombotic tendencies appear, at the present time, to be due to defects in fibrinolysis. These include hypoplasminogenemia, decreases in plasminogen activator, increases in plasminogen activator inhibitor, and Factor XII deficiency.

The majority (about 75%) of patients who suffer from acute pancreatitis do so as a consequence of gallstones or alcohol abuse. The other 25% of patients often present difficult diagnostic problems. Over several years the author has accumulated a series of patients with remedial causes of pancreatitis. They include a group of congenital conditions such as pancreas divisum, choledochal cysts and congenital abnormalities of the pancreatic ductal system. Patients who have had pancreatitis and who have an intact gallbladder often have stones that are difficult to identify. Repeated attacks of pancreatitis in the absence of any other apparent cause justifies cholecystectomy, which will often identify the cause so that recurrence can be prevented. A group of nonanatomic causes are also known. They include hyperlipidemia, drugs and toxins, certain systemic illnesses such as systemic lupus erythematosus, pregnancy, hypercalcemia, hereditary causes and occasionally cancer. In his lecture the author reviews the various etiologies of acute pancreatitis and describes an algorithm that can be used when the diagnosis is difficult.

The overall risk of oral contraceptive (OC) use is minimal when women over 35 years of age, smokers, and those with multiple risk factors (thromboembolic disorders, cerebrovascular or coronary artery disease, liver tumors, breast cancer, estrogen-dependent neoplasms, undiagnosed abnormal genital bleeding, and congenital hyperlipidemia) are excluded. OC use increases the risk of hypertension by 1-5%, depending on age, parity, and duration of use, but even this small risk is decreased when multiphasic OCs are prescribed. Deep venous thrombosis in the leg is 4 times more prevalent in OC users than nonusers and the risk of superficial thrombosis is doubled. Again, fewer thromboembolic complications occur when the estrogen dosage is low. The risk of myocardial infarction is not believed to increase with OC use as long as other risk factors--smoking, obesity, hypertension, age over 35 years, hypercholesterolemia--are not present. Studies involving the original high-dose OCs revealed a 3-fold increase in the risk of thrombotic stroke and a 2-fold increase in the risk of hemorrhagic stroke, but low-dose OCs appear to have no effect on the potential for stroke. The impact of OC use on breast cancer cannot yet be determined given the very long latency period of this cancer. In terms of benign breast disease, OC users have been shown to be at substantially reduced risk of lesions, fibroadenomas, and fibrocystic changes. OCs also protect women from endometrial and ovarian cancer, although the pill seems to accelerate the progression of cervical dysplasia. Other beneficial effects of OC use include reductions in the incidence of pelvic inflammatory disease, endometriosis, ectopic pregnancy, and ovarian cysts.

Narrow proton nuclear magnetic resonance (1H-NMR) linewidths from plasma have been associated with the presence of malignancy (Fossel et al., New Engl. J. Med. (1986) 315, 1369-1376). In that study, subjects and controls were not fasted. In the present study, 1H-NMR methyl and methylene linewidths were measured in plasma from normolipemic individuals without cancer both during fasting and every 90 min after eating a fat meal. Plasma lipoprotein levels were measured in order to relate results to postprandial lipemia. Methyl, methylene, and average 1H-NMR linewidths were strongly positively correlated with high-density lipoprotein levels and inversely correlated with triacylglycerol-rich lipoprotein levels in both the fasting and postprandial states. Linewidths decreased postprandially, reaching a nadir at the peak of plasma triacylglycerol levels. This study demonstrated that postprandial lipemia can lead to narrowing of plasma methyl and methylene resonances comparable to that reported for subjects with cancer.

Reflex sympathetic dystrophy (RSD) is a clinical syndrome defined in the English literature by pain, dystrophic tissue changes and local disturbance of autonomic function in a limb or part of a limb. Algodystrophy is the common name used for the condition in the French literature, in which the concept also includes the "transient regional osteoporosis" and the "regional migratory osteolysis". We want to discuss three points: 1) Are the RSD, transient regional osteoporosis and migratory osteolysis different diseases or different manifestations of a single condition? We believe that an objective differentiation is not possible between them. Our report about 28 cases of polytopic RSD shows the frequent association in the same patient of these manifestations and we believe that this represents the broad spectrum of a single disease. 2) Is the accepted classic pathophysiologic mechanism of RSD accurate? The conception of a disturbance of autonomic function is not easily linked with its association with conditions such as diabetes, hyperthyroidism, hyperlipidaemia and others. Even more difficult to explain is the association with malignancy and osteomalacia. The deposit of immunoglobulins that we have demonstrated in two cases in the palmar fascia of RSD associated with malignancy suggests a possible immunological mechanism. 3) What are the limits of RSD? The association between RSD and aseptic necrosis of the hip has been reported. Are they two different conditions or is the aseptic necrosis only a more developed form of RSD? Finally, we report the first single case of Munchausen syndrome mimicking a RSD of the hand with the same clinical, radiological and scintigraphic appearance.

Smoking is one of the three major cardiovascular risk factors, the other two being hyperlipidaemia and hypertension. Cardiovascular diseases contribute in Austria, as well as in other industrialized countries, more than 50% to total mortality. Unlike in other industrialized countries ischaemic heart diseases in Austria have an unfavourable mortality trend, with a substantial relative increase. The atherogenicity of smoking is partly caused by interaction with other risk factors, especially hyperlipidaemia, hypertension and a high fibrinogen level. 30% of the Austrian population are smokers. The percentage has increased over the past few years, especially in young women. Other cardiovascular risk factors are very common too and, hence, a large proportion of the Austrian population is at risk due to a combination of risk factors. Smoking and the use of oral contraceptives is associated with significant risk of both myocardial infarction and stroke. The Austrian trend of cigarette smoking among young women points to a substantial increase in the number of women at risk by this combination of risk factors. Strategies to control the smoking epidemic have been internationally tested. An integrated approach is set out in a document provided by the International Union Against Cancer (1983). In a country like Austria with a tobacco monopoly the conditions for implementing smoking control measures should theoretically be better than in other countries.

The administration of a single injection of tumor necrosis factor (TNF) produces a variety of acute and sustained biological effects, including hyperlipidemia, stimulation of hepatic lipogenesis, decreases in adipose tissue lipoprotein lipase activity, and anorexia with weight loss. Chronic administration of a fixed dose of TNF produces tachyphylaxis to the anorectic/cachectic effects of TNF. We now report that the hyperlipidemic effect of TNF persists during chronic TNF administration in the absence of any cachectic effect of TNF. Sprague-Dawley rats injected with TNF (250 micrograms/kg) show a significant decrease in weight over the next 24 h which can be accounted for by decreases in food and water intake accompanied by an increase in urine output. With subsequent daily injections of TNF, treated rats begin eating and rapidly regain weight. Hypertriglyceridemia persists for up to 10 days of daily injections of TNF. After three daily injections of TNF, no decreases were seen in lipoprotein lipase activity in a wide variety of tissues. De novo hepatic lipogenesis remained increased in TNF-treated animals after four daily injections, but by the fifth day hepatic lipogenesis returned to normal. After 5 days of TNF treatment the acute incorporation of labeled glycerol into serum triglycerides remained elevated. These data indicate that hyperlipidemia persists during multiple daily injections of TNF and that TNF induced hypertriglyceridemia is not inevitably linked to the syndrome of cachexia.

Tissues from tumor and normal intestine were examined in 44 patients suffering from colonic and rectal cancer. The study established elevated levels of cholesterol (chiefly, cholesterol esters) and phospholipids, as compared with normal tissue. Two groups were identified among the cancer patients on the basis of the ratio of K = (Formula: see text). Cases with a relatively low value of K revealed higher levels of body fat and hyperlipidemia. That was matched by relatively higher concentrations of cholesterol and its esters, but not phospholipids, in tumor tissue, as compared with normal one. The relationship between cyclic nucleotide metabolism disorders in neoplastic tissue and lipid metabolism in cancer patients is discussed.
