Histoplasmosis del sistema nervioso central: reporte de dos casos y revisión de la literatura / Histoplasmosis of the central nervous system: report of 2 cases and review of the literature

The involvement of the central nervous system by histoplasma is an infrequent complication. The clinical diagnosis is difficult because the microscopic examination and the culture of the spinal fluid are frequently negative. In this article we report two cases of meningitis by Histoplasma capsulatum in patients with acquired immunodeficiency syndrome. The first case is a meningitis without evidence of disseminated histoplasmosis in a patient who had been treated with amphotericin B. The histologic appearance was that of a granulomatous inflammation of the meninges and the underlying nervous tissue. The second case is a disseminated histoplasmosis with involvement of the central nervous system. This consists of macrophages filled with histoplasma invading the meninges and underlying nervous tissue without associated inflammation

Angiosarcoma del corazón y su ruptura espontánea. Rara causa de pericarditis efusivo-constrictiva. Presentación de un caso y revisión de la literatura / Angiosarcoma of the heart and its spontaneous rupture. A rare cause of effusive-constrictive pericarditis. A case report and review of the literature

The authors present the clinical history of a male 44 year old patient who was hospitalized with the diagnosis of pericardial constriction and effusion and operated on as an emergency because of spontaneous cardiac rupture and was found to have a cardiac adenosarcoma. They review the literature in order to discuss a very rare cause of hemopericardium and constrictive pericarditis with epidemiologic, diagnostic, therapeutic and prognostic commentaries and secondly, to try to establish if this type case does not represent a diagnostic problem for the ecocardiographer since an angiosarcoma that occupies the pericardial space can be confused with a hemopericardium. They also mention other imaging studies that are used to better characterize and diagnose these tumors

Hígado graso agudo en el embarazo: un diagnóstico a considerar / Acute fatty liver in pregnancy: a diagnosis to be considered

The clinical records and follow up of two patients with jaundice in the third trimester of pregnancy and final diagnosis of acute fatty liver of pregnancy (AFLP) are reported. The purpose of this paper is to orient clinicians on the appropriate diagnostic approach in every woman with jaundice in the third trimester of pregnancy

Síndrome de vasculitis renal y pulmonar con anticuerpos anticitoplasma de neutrófilos y anticuerpos antimembrana basal positivos: informe de un caso / The syndrome of renal and pulmonary vasculitis with positive neutrophil anticytoplasmic antibodies and antibasement membrane antibodies: a case report

The authors present a case of Goodpasture's syndrome with necrotizing vasculitis of spleen and appendix. Serological examination shows antiglomerular basement membrane antibodies and antineutrophil cytoplasmic antibodies. The authors review the literature to establish if this or other similar cases can be considered a distinct disease entity. The authors also mention the laboratory methods that are currently being used to classify more precisely the vasculitides associated with glomerulonephritis

Infección por Helicobacter pylori y el riesgo de carcinoma gástrico: presentación de un caso / Helicobacter pylori infection and the risk of gastric carcinoma: report of a case

The authors present the clinical history of a patient with gastritis of the antrum who subsequently had early gastric cancer of the antrum. The authors review the literature on the infection by Helicobacter pylori as a risk factor for gastric carcinoma. The infection produces chronic gastritis, gastric ulcer, duodenal ulcer and is a probable risk factor for gastric carcinoma

Neoplasia epitelial sólida y papilar del páncreas: descripción de dos casos / Solid and papillary epithelial neoplasm of the pancreas: report of 2 cases

Solid and papillary epithelial tumor of the pancreas occurs mainly in young women and its main characteristic is the appearance of an abdominal mass which progressively increases in size. The radiologic, surgical and pathological correlation shows that it is a tumor of low grade malignancy with a favorable prognosis, after therapy and according to the location of the tumor. The authors report the clinical history of the first two confirmed cases of this entity in Panama, which occurred in 1985 and 1992, respectively, in women less than 25 years of age

Manifestaciones cardiovasculares en el síndrome de Marfán: presentación de un caso y revisión del manejo / The cardiovascular manifestations of Marfan's syndrome: a case report and review of the management

The authors present the clinical history of a patient with Marfan's syndrome (MS) and aortic insufficiency, who expired at 22 years of age, in order to illustrate the clinical evolution and review the management of this problem. It is known that patients with MS and heart failure due to dilatation of the aortic annulus have an early mortality of almost 100%. The authors conclude that echocardiographic follow up of these patients is vital in their medical and surgical management and that the use of beta blockers is the best medical therapy, and that prophylactic surgery with composite graft (aortic valve and ascending aorta) gives the best survival rate
