Seven cases of angioma of the upper respiratory-digestive tracts are reported. The value of preoperative embolization is emphasized, treatment of choice being radical block resection of these vascular lesions. Unfortunately, this is not always possible.

Primary carcinoid of the larynx is an extremely rare neoplasm. Only seven cases could be traced in the literature so far. The authors report another case in a 71 year-old male patient. Gross examination revealed a large ulcerated tumor of the right part of the supraglottic larynx. Microscopically, the tumor was composed of nests and sheets of relatively uniform cells with round nuclei. A Grimelius stain showed positively stained granules in the cytoplasm of the cells. One cervical lymph node presented little metastatic foci of the tumor cells. A review of the medical literature showed that all laryngeal carcinoid were pathologically malignant and the treatment of choice is the surgical excision.

One hundred children presenting with acute otitis media underwent a bacteriological study of otitis exudate over a 18 month period. The bacteria found were as follows: Streptococcus pneumoniae (24), Haemophilus influenzae (19), Staphylococcus aureus (12), Streptococcus pyogenes (7), Branhamella catarrhalis (3), and 18 Gram negative bacilli (including 7 Pseudomonas aeruginosa and 11 enterobacteriaceae). One pathogenic bacterium was isolated in 56 cases, 2 or more in 12 cases and none in 32 cases. In the age categories 0-1 year (47 cases) and 1-3 years (31 cases), S. pneumoniae and H. influenzae were the main organisms found, followed by S. pyogenes in children older than 3 years (22 cases). With respect to the antibiotics used for treating otitis, 5/22 S. pneumoniae and 4/17 H. influenzae were erythromycin resistant (9/17 had an intermediate susceptibility) and 7/19 H. influenzae and 1/17 S. pneumoniae were cotrimoxazole resistant. None of the S. pneumoniae and 2/19 H. influenzae were ampicillin resistant. These 2 H. influenzae and 2/3 B. catarrhalis were beta-lactamase producers. They were sensitive to the combination of amoxicillin with clavulanic acid.
