Arteriosclerotic and nonarteriosclerotic rats were treated with carbon tetrachloride (CCL4) to induce cirrhosis of the liver. Massive myocardial infarction was then induced in intact and CCL4-treated animals. During acute necrosis (Days 1 thru 3), animals were killed at 4, 8, 12 and 24 h on Days 1 and 2, and during myocardial repair on Days 4, 5 and 8. During the induction of cirrhosis, animals developed polydypsia, polyuria, and hyperglycemia; during myocardial infarction, the arteriosclerotic + cirrhotic animals developed severe and persistent congestive heart failure, i.e., hydrothorax. Adrenal and thymus gland weights and corticosterone levels indicated that cirrhosis per se increased pituitary--adrenal activity, particularly in arteriosclerotic animals. Enzyme levels of SGOT and SGPT demonstrated severe hepatic damage due to cirrhosis and acute myocardial infarction. Blood triglycerides and cholesterol responded abnormally in cirrhotic animals during acute myocardial ischemia due to their entrapment within hepatic cells. The cirrhotic animals manifested poor myocardial repair with persistent foci of necrosis, calcification, and a high incidence of large, occlusive, atrial thrombi. It is suggested that cirrhosis interferes with lipid metabolism and adrenal steroid conjugation leading to abnormal levels of mineralocorticoids which favor congestive heart failure, poor myocardial repair, and atrial thrombosis.

Four hundred and eighty-two patients with spontaneous skin and superficial sepsis and 291 controls of similar age and sex underwent random capillary blood glucose measurements in order to assess whether screening for diabetes in patients presenting with skin sepsis to an Accident & Emergency Department detects a greater number of cases than that present in the background population. All subjects with a concentration > 7.8 mmol/l were subsequently followed up with a 75 g oral glucose tolerance test. Forty-two (8.7%) of the 482 skin sepsis patients had a capillary blood glucose > 7.8 mmol/l compared to eight (2.7%) of the 291 without sepsis (chi 2 = 9.71, P < 0.002). Of these, 26 of the skin sepsis group and 7 of the control group attended for follow up. Of those who attended, 13 of the skin sepsis group had an abnormal glucose tolerance test (seven diabetes, six impaired glucose tolerance-IGT) compared to two (one diabetes, one IGT) of the control group (chi 2 = 2.87, P < 0.1). The difference in cases of frank diabetes between the two groups was not statistically significant. Of the total eight diabetic cases identified, five (on direct questioning) had symptoms of hyperglycaemia (thirst, polyuria and/or weight loss) and two of the others were obese, one of whom had documented ischaemic heart disease. Thus, while most cases of diabetes in patients with skin sepsis could be detected by specifically asking about hyperglycaemic symptoms and performing a blood glucose estimation when these are present, we suggest that the screening of patients with skin sepsis over 40 years of age provides an opportunistic method of screening. This strategy should yield clinically significant numbers of abnormal cases.

We report the case of a 64 year old male patient with a history of ischemic heart disease who underwent surgery for an abdominal mass. The histological diagnosis was highly malignant non-Hodgkin's lymphoma. After surgery the patient was admitted to our Department and received 6 courses of chemotherapy according to the COP schedule, followed by radiotherapy to the left upper abdominal region and ipsilateral lung base. The patient achieved partial remission. One month later he began to complain of left axillary lymphadenomegaly, polydipsia and polyuria. A NMR brain scan showed a hypophyseal mass. The patient was treated with DDAVP and chemotherapy with the PRO-MACE protocol; the polyuria and lymphadenomegaly disappeared and the size of the hypophyseal mass reduced markedly. The clinical picture was, therefore, attributed to a hypophyseal localization of the non-Hodgkin's lymphoma, which is a very rare manifestation of lymphomatous spread to the central nervous system. Our case is also interesting because it shows that a favorable outcome can be obtained with chemotherapy, provided that the latter is sufficiently aggressive. This is not necessarily the case with radiotherapy which may also be followed by late and severe neurologic sequelae.
