The association of maternal and neonatal thrombocytopenia in high-risk pregnancies.

In this study of 136 women with pre-eclampsia, eclampsia, placenta previa, or abruptio placentae, 21 mothers were noted to have thrombocytopenia. Seventeen of the 21 were in the pre-eclampsia group. Of the 21 thrombocytopenic mothers, nine were associated with thrombocytopenia in the children, seven children had normal platelet counts, and five had no counts performed. Eight of the nine thrombocytopenic neonates were associated with pre-eclampsia in the mother, and five of these were not believed to have disseminated intravascular coagulation as the etiology of the platelet defect. The results suggest that thrombocytopenia is common in high-risk pregnancies in both the mother and the baby. However, the etiology of the platelet defect cannot be easily explained on the basis of a hypercoagulable state.

Kwashiorkor not associated with poverty.

Four infants are described with kwashiorkor that was unassociated with poverty or infection as predisposing factors of their disease. The condition followed various dietary regimens deficient in protein of five weeks to seven months in duration. Features of this "sugar-bady" form of kwashiorkor included a low level of physician awareness of malnutrition as a diagnostic consideration, growth retardation, edema, muscle wasting, mental changes, and mild lymphocytosis. Initially, recovery was associated with rapid loss of weight and anemia and subsequently with weight gain and return to good health.

Hageman factor and disseminated intravascular coagulation (DIC) in newborns and rabbits.

There was no significant difference in the levels of factor XII between sick newborns and normal age-matched controls, although the levels of both groups were lower than normal older children. Detailed coagulation studies on 44 sick infants revealed 11 to have disseminated intravascular coagulation (DIC). In those with DIC, the mean Hageman factor was 20% and in those without DIC, 25% (P greater than 0.05). Rabbits given a constant infusion of lysozyme (which inhibits factor XII) showed laboratory evidence of endotoxin-induced DIC. The data suggest that neither reduced factor XII levels nor Hageman factor inhibition provided protection from DIC. The data further suggest that other coagulation pathways might be involved in order to elicit the DIC.

The in vivo development of plasma cells: a morphologic study of human cerebrospinal fluid.

This is a case study of a patient with the clinical diagnosis of meningoencephalitis. It demonstrates the in vivo development of plasma cells in the central nervous system. All the stages of in vitro mitogen-induced lymphocyte transformation previously described by light and electron microscopy are recapitulated in this analysis of cerebrospinal fluid. It is postulated that this represents a local humoral immune reaction in the central nervous system and provides morphologic support for the concept that the gamma globulin in cerebrospinal fluid is produced locally in part, in addition to its origin from the plasma proteins.

Basophilic meningitis secondary to lymphoma.

In this case report of basophilic meningitis, the patient was a 5-year-old girl under treatment for a diffuse lymphocytic lymphoma. She presented with headache and bilateral papilledema. Cerebrospinal fluid examination showed 60 percent basophils. Subsequent specimens showed a rare blast. It is postulated that after the lymphoma cells had spread to the meninges, a cell-mediated immune reaction was initiated with the appearance of basophils in the exudate.

Headache in classical hemophilia. The risk of diagnostic procedures.

Headache in a hemophiliac poses a major problem. The fact that at least half of hemophiliacs with proven intracranial hemorrhage present with a headache but no preexisting injury, requires an aggressive approach to the management of these patients. Recent articles point out successful instances of craniotomy in hemophilia, but relatively few hemophiliacs with headaches progress to that stage. We have reviewed the literature and added three cases in an attempt to establish the risk of spinal puncture and cerebral angiography in the evaluation of these patients. The data presented suggests that with replacement therapy and attention to angiographic technique, both procedures may be performed with minimal risk.

Splenic artery ligation in experimental hypersplenism.

The effects of splenic artery ligation (SAL) were examined in Sprague-Dawley rats with methyl-cellulose-induced hypersplenism. When performed close to the splenic hilium, SAL effectively reduced functioning splenic mass and raised peripheral counts of leukocytes and platelets, a response similar to that following total splenectomy. In hypersplenism, therefore, a satisfactory hematologic response may not necessary require total ablation of the spleen but merely substantial reduction of functioning splenic tissue.

Effect of heparin in experimental gram-negative septicemia.

Young rabbits were given live encapsulated or heat-hilled Pasteurella multocida by the intraperitoneal route. Those animals given live organisms regularly developed clinical illness, positive blood cultures, positive limulus lysate tests on plasma, leukopenia, thrombocytopenia, and disseminated intravascular coagulation and died. Death occurred in 68% of these rabbits by 12 hr after infection and in 100% by 24 hr. Septicemic animals given heparin as an anticoagulant similarly developed clinical illness, leukopenia, and thrombocytopenia, but no laboratory evidence of disseminated intravascular coagulation. The mortality rate in these animals was 90% 12 hr after infection and 100% 24 hr after infection. None of the animals given heat-killed organisms developed leukopenia, thormbocytopenia, or disseminated intravascular coagulation, and none died. The data show that the survivial rate in septicemic rabbits was not improved with heparin, although fibrinogen consumption (disseminated intravascular coagulation) was abolished.
