On May 25, 1950, at the age of 18, this white Italian girl was admitted to Monmouth Memorial Hospital in Long Beach, New Jersey, with a diagnosis of “pneumonia.” She was found to have left pleural effusion which was aspirated on two occasions. Tubercle bacilli were found in one specimen, but the report was mislaid, and she was discharged improved. Following this, she noted fatigue and during October, 1950, right pleural effusion was found and she was readmltted to the hospital and acid-fast bacilli were found In the fluid. She was transferred to the New Jersey Sanatorium at Glen Gardner where streptomycin and PAS were administered. She had right thoracentesis on three occasions. Right pneumothorax was started and was maintained for only one month. In March, 1951, she left the sanatorium against advice. When she returned home, she resumed her full activity against the advice of her physician. During June, 1951, she was found to be pregnant. On December 3, she complained of night cough, and on December 31, 1951, a thorough physical examination was done and a chest x-ray film was taken which was unchanged. On January 1, 1952, she had vague pains and elevated temperature. She was treated by her physician with an antibiotic without results. That evening, she was admitted to the hospital, and on January 2, had a normal delivery of a baby boy. During her stay in the hospital, she had persistent low-grade fever. She had persistent cough on discharge from the hospital. She was readmitted on January 30, when a chest x-ray film suggested mlliary tuberculosis. Six weeks later, she was again admitted to the New Jersey Sanatorium when a gastric specimen was found positive for tubercle bacilli. She was treated with streptomycin, PAS and INH and subsequently discharged in good condition. Her last examination was on October 5, 1960, when she was well and her x-ray film was clear. Her child is in good health and does not react to tuberculin.
