of the tests. One subject had definite exophoria at the outset and therefore passed through a stage of orthophoria before becoming esophoria The diplopia that results from alcohol is asssociated with a reduction, not with an increase, in convergence power and is dependent on the development of esophoria too great to be overcome by the abduction power, although this remains unchanged.In a recent communication I reported a series of cases of acute Friedl\l=a"\nder pneumonia, giving reasons for considering this disease as a distinct and primary form of pneumonia.1 Before proceeding to a description of chronic lung infections caused by the Freidl\l=a"\nderbacillus (Bacillus mucosus capsulatus), the essential features of the acute disease will be reviewed briefly.In common with other pneumonias, the onset is usually sudden, with chills, fever, cough and pain. The clinical course, however, is fulminating and the mortality extremely high. Certain other features serve further to distinguish Friedl\l=a"\nder pneumonia from other forms : 1. Pneumonia due to the Friedl\l=a"\nderbacillus comprises from 1 to 3 per cent of all pneumonias and occurs almost exclusively in the later decades of life with a considerable preponderance of males over females. It almost never occurs in children.2. Hemoptysis is a frequent initial symptom in this disease. Herpes is uncommon, but jaundice is a rather frequent accompaniment.3. Though the lesion is lobar in distribution, the classic signs of consolidation such as bronchial breathing and pectoriloquy are absent in about half the cases. When one observes the heavy, soggy lung at necropsy, the dulness and suppressed breath sounds are readily explained. Involvement of the upper lobe and involvement of more than one lobe are frequent.4. The temperature is less regular, and low grade fever is more common than in pneumococcic pneumonia. 5. The gross appearance of the sputum generally is charac¬ teristic. It is that of a brick-red homogeneous emulsion of blood and mucus, in contrast to the rusty taffy-like sputum of pneu¬ mococcic pneumonia. A direct smear of the sputum stained by Gram's method will usually show a predominance of the typical gram-negative bacilli surrounded by a clearer zone representing the capsule. Inoculation of the sputum into the mouse, an animal extremely susceptible to this organism, will invariably confirm the diagnosis.6. Pure cultures of the Friedländer bacillus are obtained from the sputum, from the lung juice and frequently from the blood cultures.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
