Drugs and recurrent ocular herpes.

There are two types of ocular herpes simplex virus (HSV), type 1 and type 2, and infections can be primary or recurrent. This paper reviews characteristics of herpes infections, the prevalence of the disease, virus latency and reactivation, types of ocular involvement, and current concepts for the management of ocular HSV. Various exogenous factors associated with recurrent herpes of the eye are covered with an emphasis placed on corticosteroids, epinephrine, and medroxyprogesterone.

Occult bronchogenic carcinoma masquerading as esophageal cancer. Case reports with recommendations for a change in reporting esophageal cytology.

We describe two patients with benign esophageal stricture in whom exfoliative esophageal cytologic features positive for squamous cell carcinoma is attributed to roentgenographically occult lung cancer. The discovery of alveolar macrophages within the esophageal washings of these patients prompted a retrospective analysis assessing the prevalence of esophageal washings contaminated by cellular material from the lower respiratory tract. Alveolar macrophages were observed in 11 of 28 patients (39%) and in 12 of 33 specimens (36%).

Bronchial brushing in bronchogenic carcinoma. Factors influencing cellular yield and diagnostic accuracy.

In a prospective study, varying the bronchial brushing technique through the flexible fiberoptic bronchoscope was examined for the effects of cellular yield and diagnostic accuracy. The yield of cells obtained from the 1.7-mm brush was increased by more than twofold when the brush and bronchoscope were withdrawn as a unit through the pharynx and nose, (nonwithdrawn brushing), rather than withdrawing the brush alone through the aspiration channel of the bronchoscope (withdrawn brushing).
