It has been suspected that the increased sympathetic activity seen in patients with chronic congestive heart failure from dilated cardiomyopathy may be harmful. We therefore tested the long-term effect of metoprolol on eight patients in a double-blind, randomized protocol and 12 patients in an unblinded, crossover protocol who were treated for 12 months (range 10 to 24), and compared them with 16 similar subjects who were treated with placebo for 10 months (range 6 to 12) in a double-blind, randomized protocol. Patients were followed by serial clinical assessment, treadmill testing, radionuclide ventriculography, and echocardiography. Metoprolol-treated patients had an improvement in mean exercise capacity by 3
mets
(p less than .0001) while experiencing a significant improvement in functional classification (p less than .001) during both the double-blind and open-label crossover studies and had an improved ejection fraction during the double-blind study (p less than .02). These improvements were not seen in matched control subjects receiving placebo. Seven of 20 patients receiving long-term metoprolol therapy had resolution of nearly all symptoms of
heart failure
, doubled their exercise capacity, and had progressive improvement in resting radionuclide left ventricular ejection fraction (12.6 +/- 3% to 26.9 +/- 6%) and echocardiographic left ventricular end-diastolic dimension (7.7 +/- 0.5 to 6.5 +/- 0.5 cm). Only one of 21 patients treated was intolerant of metoprolol. We conclude that metoprolol can be given safely to a select group of patients with dilated cardiomyopathy in doses that substantially reduce both resting and exercise heart rates. Long-term beta-blockade improved functional class and exercise capacity in 14 of 20 patients while producing an exceptional clinical response in seven that was accompanied by improved resting parameters of left ventricular function.

Metastatic pericarditis was identified in 74 out of 240 cancer patients suffering from
secondary tumor
lesions in the heart (30.8%). It involved quick accumulation of exudate which led to grave
heart failure
due to cardiac tamponade development in 39%. Liquid in the heart sac was detected by X-rays in 20, ECG-39, and echocardiography--in 83% of patients. Application of echocardiography provides a means for ascertaining the extent of pericardial involvement and monitoring changes in tumor process occurring in the course of therapy.

Colonic pseudo-obstruction (Ogilvie's syndrome) may occur in surgical patients, particularly those who have had orthopedic or blunt trauma, have uremia or diabetes, have complex metabolic or
cardiac failure
, have
metastatic cancer
involving the lymph nodes and neural tissue, or are addicted to narcotics. Although a single true cause has not been identified by fulfilling Koch's postulates, the clinical pattern has been recognized in a variety of surgical patients, and this pattern must be distinguished from true obstruction of the colon. Tumor or internal hernia may constitute an obstruction, but the important differential diagnosis of cecal volvulus must be excluded. Ischemic colitis may be confused with Ogilvie's syndrome or may follow it. Gangrene, infarction, and perforation may ensue as colon diameter increases and particularly if cecal distention reaches above 14 cm. This arbitrary number for cecal dilatation should not be awaited before treatment is instituted if signs of devitalization of the gut or peritoneal signs have developed in the patient. Treatment has changed recently with the widespread application of colonoscopy. Endoscopy is helpful in relieving distention but may also be dangerous in the patient with a massively distended colon, particularly at the level of the thin-walled cecum. Colonoscopy also appears to be associated with a high rate of treatment failure and recurrence. Surgical decompression may take the form of cecostomy or may require exteriorization or resection of the colon if infarction has occurred. A series of 12 patients has been presented. The patients were all referred to a single surgeon in a university medical center over a 4 1/2 year period with clinical patterns not suggestive of a common cause but a similar clinical evolution of Ogilvie's syndrome. The prognosis for such patients in whom the complication is recognized early and in whom decompression is performed endoscopically or surgically is encouraging. If recognition is late and particularly if perforation and gangrene result, mortality is nearly 50 percent.

Benign liver tumors are relatively uncommon and, even when large enough to be symptomatic, they usually remain undiagnosed prior to exploratory laparotomy. Hemangiomas constitute the majority of benign hepatic neoplasms and are 9 times as frequent in females as in males. Most are asymptomatic but abdominal swelling, a mass, or symptoms due to compression of adjacent organs may occur and abdominal hemorrhage is reported in 4.5% of patients. Hepatic hemangioma may produce a large arteriovenous communication serious enough to cause
heart failure
. Recently an increased frequency of liver tumors, mostly adenomas, has been noted in women taking oral contraceptives (OCs); the cause has been attributed to estrogens. The exact incidence is unknown but believed to be low. It is most common in women in their late 20s who have been on OCs for 7 years or more. The tumor occasionally completely regresses on withdrawal of the OCs. The tumor may be discovered incidentally at laparotomy or may manifest inself by pain, a palpable mass, or catastrophic hemoperitoneum. Hepatic adenoma is usually a solitary lesion and infrequently degenerates into malignancy. Differential diagnosis includes chronic gall bladder disease and peptic ulcer. Focal nodular hyperplasia (FNH) is apparently much less frequently related to OC use and is less likely to bleed seriously than adenoma. Hepatic chemistry is usually normal in adenoma and FNH, but slight increases in serum bilirubin, serum alkaline phosphatase, and serum transaminase may occur. Primary liver cancer (hepatocellular carcinoma or hepatoma) is mostly a disease of males and in the US and Western Europe seldom develops before age 40. Fibrolamellar carcinoma, which characteristically develops in adolescents and young adults, occurs with equal sex incidence. Doubt has been expressed about its relationship to OCs. In the US about 75% of primary hepatocellular carcinomas are associated with cirrhosis, and about 5% of cirrhosis cases develop primary liver cancer. Clinical manifestations of hepatoma have been divided into 5 groups: frank cancer (62.7%), acute abdominal cancer (8%), febrile cancer (8%), occult cancer (16%), and
metastatic cancer
(5%). Detection of large amounts of alpha fetoprotein has proven useful in diagnosis of hepatocellular carcinoma, but values may be negative in OC users. It has been estimated that 1/3 to 1/2 of all malignant tumors eventually
metastasize
to the liver.

A case, unique in the literature, is reported in which a primary carcinoma of the liver presented a right-sided
heart failure
and pulmonary hypertension. The diagnosis of hepatocarcinoma was established by needle biopsy of the liver. Later, postmortem examination demonstrated that the pulmonary arterial tree was severely compromised by multiple tumor microemboli, despite the persistent lack of characteristic roentgenographic abnormality in our patient. In reviewing the literature, we found rare cases of occult renal cell carcinoma, choriocarcinoma and one of occult hepatocarcinoma, which presented as pulmonary embolism. These were diagnosed by pulmonary embolectomy, human chorionic gonadotrophin levels or autopsy, respectively. In another small group of reported cases of known carcinoma (gastric, breast, colonic) the patients had a clinical picture of "idiopathic" pulmonary hypertension or of pulmonary hypertension with pulmonary
metastases
. Pulmonary hypertension in these cases resulted from carcinomatous lymphangitis and/or tumor microembolization, as in our case. We report this case to emphasize the necessity of including occult carcinoma in the differential diagnosis of pulmonary hypertension and right ventricular failure.

Five observations of hepatoblastoma in boys of 10 months to 4 years of age are presented. Tumor mass in the right part of the abdominal cavity was detected 1--9 months before death. Three patients died of pulmonary
cardiac insufficiency
, 2 of cateterization sepsis and hepatic insufficiency. The liver weight varied from 840 to 3500 g. Two children had intrahepatic
metastases
, one of them also had extrahepatic
metastases
into the portal lymph nodes and lungs. In 2 observations hepatoblastoma was of an epithelial structure, in 3 cases of a mixed type. It is suggested that hepatoblastoma, as well as liver carcinoma in adults, occurs more frequently in males.

Hepatic tumors have been associated with oral contraceptive (OC) use. Klatkin's literature review of 1976 yielded a total of 237 cases of OC-associated hepatic tumors; 9% of these were considered malignant. This paper presents a case of liver cell adenoma which developed when a 34-year old patient was using OCs. Contraceptive use was discontinued and the lesion regressed, but a hepatocellular carcinoma developed 3 years later. The woman presented in 1976 complaining of acute right upper quadrant abdominal pain. A hemorrhagic hepatic tumor 16 cm in diameter was diagnosed after an exploratory laparotomy. The patient discontinued use of Ovulen 21 which she had been using for 5 years and was followed up with serial liver scans. The mass shrank to approximately 5 cm in diameter by January 1979 and remained stable until November 1979 when liver scan revealed that the tumor had reverted to its 16 cm size. In December 1979, a partial hepatectomy was done but it was complicated by a cardiac arrest. A postpericardiotomy syndrome developed after the operation. 5 weeks postoperatively, in January 1980, the patient suffered constrictive pericarditis and a pericardial stripping operation was done. The patient later died of sepsis with high output
cardiac failure
, shock, and adult respiratory distress syndrome. Ultrastructural studies of the tumor revealed a well-differentiated hepatocellular carcinoma. The features of the tumor (e.g., travecular growth, necrosis, hemorrhage) have been the criteria, in addition to vascular invasion and
metastases
, used to classify previously reported cases as malignant. Autopsy of the patient revealed no metastatic lesions. Cytoplasmic structures suggestive of a phospholipid disturbance were also observed and were thought to be related to drug interference with phospholipid metabolism. An interesting observation was the regression of the tumor after discontinuance of pill use. The mechanisms of its renewed growth and its malignant change remain unknown. Lesions such as this should be given a guarded prognosis even if the appearance is benign. Possible metabolic or enzyme deficiency in the few women in whom hepatic tumors develop is raised.

Among 2175 patients seen over the last three years in a non-specialized department of internal medicine with no intensive care unit, 100 had supranormal serum lactic dehydrogenase activities. These patients' case-reports have been analyzed. Nearly half the patients (47/100) had a malignant disease (cancer or hemopathy). Among the remaining patients, 19 had a hepatic disorder (alcohol hepatitis in 10, viral hepatitis in 8, and isoniazide hepatitis in 1), 7 had a heart disease (
heart failure
with hepatomegaly in 5, myocardial infarction in 2), and 27 had various other conditions (including hemolysis in 6 and polymyositis en 3). The value of serum LDH assay is obvious in situations other than acute conditions such as myocardial infarction of pulmonary embolism; these are better known and have not been studied here as their prevalence was low among the patients enlisted in our study. In comparison to other enzymes (alkaline phosphatase (AP), gamma-glutamyl transpeptidase (GGT), transaminases (GOT, GPT) that were also routinely assayed in our patients, abnormal serum LDH activities are much less common and their significance is quite different. An increase in serum and their significance is quite different. An increase in serum LDH activity indicates a serious condition, often with a fatal outcome. The "various other conditions" group includes patients with hemolysis, hepatitis and myositis; the other patients in this group either had severe infectious diseases or died suddenly in the first few days of their hospitalization before diagnosis had been established. Each etiologic group has been analyzed to asses the characteristics of patients with increased LDH activity according to each etiology. Analysis of coincident abnormalities of the other enzymes listed above shows marked differences between etiologic groups; diagnostic accuracy can thus be enhanced in certain conditions. Most patients with malignancies had poorly differentiated tumors, with
metastases
: 28 had an epithelial tumor, with hepatic and/or bone metastases in 23 cases, 5 had cancer of the liver, 10 had a malignant hemopathy (2 lymphomas, 5 myeloproliferative syndromes, 3 acute leukemias), and 4 had a sarcoma. Cancer of the lung is the most common malignancy (10 cases) and may be responsible for increased serum LDH activity even in patients without
metastases
. Serum LDH assay is of value for monitoring the course in patients with initially increased activities as it falls under effective therapy and rises during exacerbations.

Fifty-five patients with newly diagnosed, estrogen receptor negative, metastatic breast cancer were entered in a trial of mitoxantrone, 10 mg/m2 intravenous (IV), cyclophosphamide, 500 mg/m2 IV, and 5-fluorouracil, 1000 mg/m2 IV, which were given on day 1 of a 21-day treatment interval. This trial was designed to test the efficacy of substituting mitoxantrone for doxorubicin as part of a combination that has proved to be effective in inducing remission. The trial was also intended to evaluate the response of resistant disease and of stable
metastatic disease
to a combination of doxorubicin and vinblastine sulfate. The cardiotoxic potential of mitoxantrone was evaluated in all the patients by serial measurements of ejection fraction and by endocardial biopsy of the right ventricle. Patients who achieved a complete response or a partial response (with bone as the only site of disease) on the three-drug combination were continued on this treatment for 2 years, or for 1 year following a complete response, whichever was shorter or as cardiac monitoring permitted. Therapy with doxorubicin, 25 mg/m2/d for two days, followed by continuous infusion vinblastine sulfate, 1.4 mg/m2/d for four days, was given to all patients who progressed after two courses or were stable after six courses of three-drug therapy. The preliminary results from 50 patients show that 4 attained a complete response and 30 a partial response, giving a total response rate of 68%. The median duration of response was more than 7 months (range greater than 5 to greater than 15 months). One patient in complete remission relapsed after 8 months and failed reinduction therapy with doxorubicin-vinblastine sulfate. Myelosuppression, principally granulocytopenia, was the major side effect of cyclophosphamide-mitoxantrone-5-fluorouracil. Mild to moderate vomiting occurred in 76% of patients and alopecia in 88%. This therapy was discontinued in four patients because of a decreased cardiac ejection fraction and/or symptoms of
heart failure
. No cardiac biopsy score, however, has been greater than 1.0. These results suggest that a combination of cyclophosphamide-mitoxantrone-5-fluorouracil is effective in untreated, estrogen receptor negative, metastatic breast cancer and is comparable to the doxorubicin combination. Myocardial injury occurs with mitoxantrone, and a safe cumulative dose has yet to be established.

Eighteen patients with severe symptoms of the carcinoid syndrome were assessed for hepatic embolisation. Four were too ill, and one had mild symptoms; thus 13 received a periembolisation regimen of cyproheptadine, fenclonine, aprotinin, methylprednisolone, tobramycin, flucloxacillin, and metronidazole. Embolisation was not performed in one patient with an occluded portal vein and was unsatisfactory in two others, in one because she was moribund and in the other because the hepatic artery had been ligated. Dramatic improvement in symptoms occurred in the nine patients in whom embolisation was successfully carried out, with abolition of flushing, severe abdominal pain, and wheeze and reduction in diarrhoea from 10.5 (SD 7.6) to 1.6 (0.9) stools/day. Urinary excretion of 5-hydroxyindole acetic acid fell from 1048 (716) to 289 (184) mumol/24 h (200 (137) to 55 (35) mg/24 h). Complications included one death from septicaemia, a hepatic abscess requiring surgical drainage, abdominal pain in three patients, pleural effusion in two, and transient encephalopathy in one. Relief of symptoms lasted for one to 24 months, and second embolisation in two patients produced further remissions of four to six months. Five patients died, one to 40 months after embolisation, in four cases because of
metastases
or
heart failure
. Hepatic embolisation is the treatment of choice for symptoms of the carcinoid syndrome resistant to medical treatment.
