Vocal Fold Polyps and Nodules. A 10-Year Review of 1,156 Patients

We investigated the clinical records of 784 patients with vocal fold polyps and 372 patients with vocal fold nodules who were seen in our clinic during the 10 years from 1971 to 1980. Polyps were frequent in middle ages in both sexes whereas nodules were common in boys and middle-aged women. Vocal abuse was the most important etiologic factor. No regular voice therapy was available for lack of voice therapists. Surgical removal yielded the best result, but not in all the patients operated.

Intrauterine candida infection in premature baby.

An autopsy case of pulmonary candidiasis occurring in a neonatal girl was reported. The mycological examination of the lung taken at autopsy revealed only Candida albicans and followed by the elucidation under the microscopic sections prepared with special stains; periodic acid‐Schiff and methenamine silver, in the lung, stomach, umbilical cord, and amnion. The presence of Candida vaginitis in her mother supported the concept that Candida albicans was the etiological agent of the pulmonary candidiasis.

RHABDOMYOSARCOMA OF THE RIGHT VENTRICLE

A case of a 66‐year‐old male with rhabdomyosarcoma of the right ventricle who presented first with a pleuritic chest pain and later developed congestive heart failure with A‐V block is described. The total period of the disease was about 9 months. At autopsy the right ventricle and wall were found to be replaced by tumor tissue which was diagnosed histologically as rhabdomyosarcoma of the alveolar type. We described one case and 52 rhabdomyosarcomas of the heart from the literature; the ages ranged from 3 months to 92 years with 29 men and 23 women (unknown 1). The primary lesions were right ventricle 29%, right atrium 26%, left atrium 24%, left ventricle 6%, and others 15%.

A Study of Nasal Epithelial Changes; A Clinical Evaluation by Eosin Stain Test.

(1) In a pathological study using the eosin stain test on nasal abnormalities in 343 out patient clinic patients from October 1997 to April 1998 a period in which pollen epidemics were not prominent, eosinophilic cells were not always found (60%) in allergic rhinitis or allergic sinusitis. In both diseases the color of the stained background was purple-pink to purple. Otherwise, in sinusitis the color was pink. (2) Ciliated columnar cells had a tendency to form clusters in allergic rhinitis and allergic sinusitis. Otherwise in sinusitis not clustered. (3) These findings show that nasal ciliated columnar cells behave like a kind of sensor of the nasal environment.
