[Angioimmunoblastic lymphadenopathy with dysproteinemia. The first reported case at the "Santo Tomás" Hospital].

Description of the first case of angio-immunoblastic lymphadenopathy with dysproteinemia diagnosed in a male patient 64 years old and which preceded the development of a lymphoma. The importance of this study is the association that may exist between certain drugs and the development of angioimmunoblastic lymphadenopathy, which occurred in our patient with the use of diphenylhydantoin. This disease can present itself up to 22 years after exposure to the agent.

[Thymoma of fusiform cells. Report of a case].

A 63 yo female was hospitalized with a 2 week history of vomiting, epigastric pain, anorexia and weight loss. She had an incidental finding of left anterior upper mediastinal mass on Chest Xray and TSP of 2.2 gm% and globulins of 1.2 gm% along with endobronchial larvae of Ascaris lumbricoides and malignant cells and Strongyloides stercoralis in the gastric mucosa. She died after a progressively deteriorating course and at autopsy a thymoma predominantly composed of spindle shaped cells was found. This rare variant of thymoma has been associated with red cell agenesis and with immunodeficiency (Good's syndrome).

Spontaneous resolution of colonic strictures caused by necrotizing enterocolitis: therapeutic implications.

Colonic strictures are now a well recognized complication in infants surviving necrotizing enterocolitis. We describe the clinical course of seven infants with colonic strictures after necrotizing enterocolitis. Only two demonstrated the finding of fixed fibrotic stricture described in the literature, while the remaining five showed atypical radiographic and pathologic features. Two of the five showed partial or spontaneous resolution of post-necrotizing enterocolitis colonic stenoses on follow-up barium enema studies. In three of four patients with colonic resections, the histopathologic examination revealed a surprising absence of irreversible fibrosis or cicatrix formation. Current surgical practice dictates elective resection of these narrowed colonic segments. The radiologic and pathologic findings in our series of patients suggest surgical resection may be unnecessary in selected cases.

Auditory and visual defects resulting from symptomatic and subclinical congenital cytomegaloviral and toxoplasma infections.

Sensorineural hearing loss was present in ten of 59 (17%) patients with congenital cytomegalovirus (CMV) infection (three of eight born with symptomatic and seven of 51 born with subclinical infection). The defect was bilateral in eight, moderate to profound in eight, and of progressive nature in two. Hearing loss did not occur in 21 patients with natal CMV infection nor in seven of 12 patients with congenital toxoplasmosis. Histopathologic and immunofluorescent studies of the inner ear in two of three neonates who died with severe infection revealed that viral antigens were widely distributed in cochlear structures. Eye pathology was associated only with congenital Toxoplasma (nine of 12) and CMV (seven of 43) infections. Visual impairments were more prominent and severe in those born with symptomatic infections, exclusively so with CMV. However, ocular defects, in particular chorioretinitis, developed after birth in five of eight patients born with asymptomatic congenital toxoplasmosis. These data firmly establish clinically inapparent congenital CMV infection as a major public health problem and confirm the fact that congenital toxoplasmosis may be associated with late-appearing, debilitating chorioretinitis.

Congenital tuberculosis.

Congenital tuberculosis is a rare and often fatal disease. This report concerned a premature infant in whom the disease was found after postpartum diagnosis in the mother. Use of endotracheal tube aspirates to diagnose tuberculosis in the infant is a unique feature of this case.

The placental pathology of small-for-gestational age infants.

There is a lack of placental studies of newborn infants who are small for gestational age (SGA). In a gross and light micorscopy evaluation of 63 referred placentas associated with singleton SGA infants, abnormalities were found in 58. In many instances these were considered of causal significance. Abnormalities included ischemic lesions (43 per cent), often related to a history of pre-eclampsia. In this group of specimens, severe X-cell proliferation was present, possibly related to a mechanism of delay of the onset of lavor. Approximately 25 per cent of the placentas showed villitis of unknown etiology. This is presumed to be of infectious etiology, probably viral. Sixteen per cent of the infants died.

Single umbilical artery. Correlation of clinical status and umbilical cord histology.

Although numerous reports are available concerning infants who have single umbilical artery, there are no studies that correlate the incidence of congenital malformations or prognosis of such infants with the presence or absence of an atrophied artery in their associated umbilical cords. For this reason, we studied 48 infants who have single umbilical artery. No significant differences were detected in congenital malformations or neonatal mortality between infants with atrophy of one of their arteries and infants with arterial aplasia.
