Acute isolated myocarditis: Report of a case,with a study of the development of the lesion

The term “acute isolated myocarditis,” now used instead of “acute primary myocarditis,” should designate a disease in which inflammation of the myocardium is the only important active acute lesion in the body. The disease may be due to actual infection of the myocardium, or, as in experimental animals and very probably in man, to the effect of chemical action alone or chemical and other factors acting simultaneously on the heart. In some cases the etiology remains obscure, hence the term “idiopathic.” The disease regularly runs its full course without being recognized, despite the fact that it has been periodically considered and quite well defined in the foreign medical literature during the past thirty-six years. It is only recently that a few reports have appeared in the American literature. Our recent experience with a case prompted us to make a survey of the literature, from which we learned that there is a group of symptoms which seem distinctive. Our survey was extended to include the various chemicals used singly or in combination in the experimental production of acute myocarditis. We wished to know particularly whether experimental myocarditis paralleled acute isolated myocarditis in severity of injury and reaction. Our own case afforded an unusually good opportunity to study the development of the myocardial lesions. By reporting it, and summarizing the important clinical and pathologic characteristics of all the cases in the literature, we hope to facilitate the diagnosis of this elusive disease.     

Acute isolated myocarditis

The clinical and pathological observations on two cases of acute isolated myocarditis of undetermined etiology are recorded, together with a tabulation of the pertinent data in thirty similar cases previously reported.     

Necrotizing fasciitis in adults due to group B streptococcus. Report of a case and review of the literature

Necrotizing fasciitis is an uncommon severe infection involving subcutaneous tissues and advancing along fascial planes. Group B streptococcal infections occur disproportionately in diabetics and pregnant women. Although fasciitis secondary to group B streptococcus has been described in infants and adult women in the postpartum period, we report the first case, to our knowledge, of group B streptococcal necrotizing fasciitis in an adult diabetic unrelated to obstetric complications.     

Acute coronary artery occlusion likely due to thrombus occurring during coronary angiography: Report of a case

Twenty-five years ago, fatalities due to acute thrombotic coronary occlusion occurring during coronary angiography were reported not infrequently, but are thought to have been eliminated by changes in technique and equipment. We present a case with documentation of a normal coronary arterial tree just before the time of an abrupt occlusion, which had the angiographic features of clot. The likely source of the thrombus was the arterial sheath. Measures for prevention of this complication are discussed. Cathet. Cardiovasc. Diagn. 43:460–462, 1998. © 1998 Wiley-Liss, Inc.     

Acute hepatitis with bridging necrosis due to hydralazine intake. Report of a case.

A 59-year-old woman was admitted to the hospital for evaluation of her hypertension. She was treated with hydralazine; two days later a severe acute hepatitis supervened. On discontinuation of the agent, the liver damage disappeared, relapsed during inadvertent rechallenge, and healed following permanent withdrawal from the drug. Histologic study of the liver showed severe acute hepatitis with bridging necrosis (so-called subacute hepatitis). Six months after discontinuation of hydralazine, a second liver biopsy specimen showed a complete remission of the disease. This hydralazine-induced hepatitis appears to be fully reversible and to differ both on clinical and histological grounds from two previous reports documenting a granulomatous liver disease.     

Acute urinary retention due to retrovesical hematoma: a case report

Acute urinary retention is a urologic emergency, which has a meaningful impact on patients' quality of life. The compression of retrovesical hematoma is a rare cause of urinary retention. We report the presentation and discuss the differential diagnosis of acute urinary retention due to retrovesical hematoma in a 57-year-old male patient.

Rectal bleeding due to (Esophagostomum brumpti: Report of a case

Summary A case of oesophagostomiasis of the large intestine in a black Ethiopian sailor is described. Diagnosis was made histologically by finding the parasite in nodules of the intestinal wall. A review of the literature is included.     

Acute pancreatitis possibly due to arginine use: a case report.

Arginine has been used by millions of athletes over the past 20 years to enhance production of human growth hormone. The effects of arginine supplementation include increased fat burning and muscle building, enhanced immunity, and improvement in erectile function in men. Excessive doses of basic amino acids such as ethionine, methionine and lysine are known to damage the rat pancreas. Recent studies have demonstrated that excessive doses of arginine induce necrotizing pancreatitis in rats. In this article, we report a 16-year-old male patient hospitalized in our clinic because of severe pain in upper abdomen, nausea and vomiting who was suspected to have arginine-induced acute pancreatitis.
