Recent studies of Guillain-Barré syndrome in adults have shown that the requirement for assisted ventilation correlates closely with a poor outcome, and the need for ventilation is now being used as an indication for plasmapheresis. As comparable studies in children have not been performed we reviewed our experience of patients who had Guillain-Barré syndrome severe enough to require assisted ventilation. In a group of 11 children two died in the acute stage of the illness and nine made an excellent recovery. It would seem that the need for mechanical ventilation is not necessarily a bad prognostic factor for neurological recovery in children. [ABSTRACT FROM AUTHOR]

Sixteen blind babies who were considered to be showing the characteristics of delayed visual maturation were studied prospectively. The diagnosis was made on clinical grounds, and the criteria for this are discussed. All of these infants developed visual responses between 4 and 6 months of age and had normal or near normal visual acuities by 1 year of age. Long term follow up, however, has shown neurological abnormalities in some of these children. [ABSTRACT FROM AUTHOR]

Malaria, the number one disease in the world, is caused by intracellular protozoans belonging to the Subphylum, Sporozoa; Suborder, Haemosphoridia; and Family, Plasmodiidae. The four classical organisms producing disease in man are Plasmodium vivax, P. falciparum, P. malariae, and P. ovale. Although malaria has been known to man for centuries, attempts are still being made to control and eliminate its devastating effects in tropical and subtropical areas of the world. Current active interest in malarial immunology and immunopathology derives from two main facts: (1) that human malaria is still one of the chief health problems in a broad tropical and subtropical zone in which lie most of the developing countries; and (2) most of the seminal leads in basic immunology are being applied to malarial immunology, either directly in human patients, or using laboratory animals as test objects.This paper addresses the nature of malarial immunity and target organs in malarial pathology.

Malnutrition combined with susceptibility to infection threatens the health and survival of a large portion of the world's population. Of the many components of the host-parasite relation, nutrition has not received the attention it deserves. There has been increasing activity in recent years on the elucidation of the role nutritional factors play in the behavior of both host and parasite.This paper reviews the effects vitamins exert on the course of parasitic infections.

Accumulative evidence in the scientific literature relating malnutrition and susceptibility to infection in human beings and animals has contributed significantly to the understanding of the maladies among the malnourished of the world. In the dispensation of health care systems around the world, little or no emphasis has been placed on trace-element nutrition. This paper adds to the available evidence by using a metabolic imbalance technique to investigate the effects zinc deficiency exert on the course of a parasitic infection. A model composed of zinc-deficient mice and Trypanosoma musculi was used to study changes in serum immunoglobulins.

Although malaria and hookworm disease appear to be on the decline, another dreaded parasitic disease-schistosomiasis-is on the increase. Presently, the number of infected individuals with schistosomes is estimated to be 250 million, and even though only a small proportion of them become sick and die, schistosomiasis remains a medical problem of great significance. The high incidence of infection of man with Schistosoma mansoni, Schistosoma japonicum or Schistosoma haematobium, as well as the chronic debilitating diseases produced, places these organisms among the world's most important infectious agents. This paper discusses the nature of immunity to schistosomiasis.
