Abstract: Nerve fibre bundle visual field defects are the hallmark of pathology at the optic nerve head or retina. In the present series, six eyes of four patients with large intracranial mass lesions demonstrated such field defects with visual acuity spared in three of the involved eyes. In no cases did visual function in the opposite eye offer a clue to the localization of the lesion.

Abstract: Artificial ventilation is a cornerstone of basic life support-cardiopulmonary resuscitation (BLS-CPR). Recent data corroborate clinical studies performed in the 1950s and 1960s, suggesting a need to change the present American Heart Association standards for artificial ventilation. These studies show that gastric insufflation followed by regurgitation and pulmonary aspiration are a major hazard of artificial ventilation with an unprotected airway. Present BLS-CPR standards require that ventilation be performed rapidly between external chest compressions or with incremental breaths. These methods of ventilation predispose the victim to gastric insufflation. Alternative methods of ventilation with longer inspiratory time and thus lower flow rate and peak inspiratory pressure are suggested. Additionally, rescue personnel, particularly EMTs and paramedics, should be taught how to apply cricoid pressure to prevent gastric insufflation in victims with an unprotected airway.

Abstract: This report describes alterations in functional responses to lectin-induced stimulation of peripheral blood lymphocytes and in the natural killer cell (NKC) activity, of college students, obtained during an outbreak of influenza A/Philippines/2/82(H3N2) virus infection. These results are compared with similar observations in college students with an acute, febrile, noninfluenzal respiratory illness that occurred during the same outbreak. The lymphopenia typical of influenza during acute illness was shown to be due to a reduction in both T and B cells without alteration in the CD4:CD8 ratio. In addition, phytohemagglutinin and concanavalin A responses were reduced and NKC activity was increased, while pokeweed mitogen reactivity was unaltered at the time of admission to the study. Patients with noninfluenzal illness showed early polymorphonuclear leukocytosis and a similar lymphopenia. Lymphocyte functions were virtually unchanged during acute illness in noninfluenza patients. The relatively specific alterations in lymphocyte responses to lectin-induced stimulation in influenza patients may indicate that the peripheral T cells are incapable of activation via the CD3 or CD2 activation pathways. In addition, increased NKC activity in the periphery may be reflective of increased NKC activity in the lung. Influenza-infected individuals with higher NKC activity at the time of admission to the study also took longer to recover. Finally, the early lymphopenia and the later neutropenia in the influenza-infected patient may represent migration of these cells from the circulation to the infected respiratory tract as a consequence of infection.
