Vocal cord paralysis in postpoliomyelitis syndrome.

Postpoliomyelitis syndrome is characterized by new neuromuscular symptoms, including weakness, developing years after recovery from acute polio. Bilateral vocal cord paralysis is presented as a new manifestation of this syndrome. Other clinical features of post-poliomyelitis syndrome in this report are discussed. The etiology of this syndrome is unknown, though attrition or immune-mediated destruction of collateral muscular innervation appears likely. The pathologic findings include scattered individual muscle fiber atrophy as well as evidence of chronic denervation and reinnervation. This form of motor deterioration is not life-threatening, but potentially may cause increasing disability in a large number of polio survivors. Proper supportive care of facial, laryngeal, and pharyngeal weakness is crucial in the management of these patients.

A clinical and anatomical study of the various techniques of irrigation of the maxillary sinus.

Irrigation of the maxillary sinus is a common procedure in clinical practice for removing the contents of the antrum for either diagnosis or therapy. For many years, it has been accomplished by inserting a trocar in either the natural ostium or the medial wall of the sinus under the inferior turbinate. Recently, the anterior wall of the maxillary sinus has been re-introduced as a better route. It is more direct and is the only one suited for use in a child whose sinus is underdeveloped. The anterior route has been termed the canine fossa technique and is the preferred route since it has a high degree of patient acceptance and safety and can be done easily and quickly by the clinician through a familiar anatomical pathway.

Sinoscopy and sinus disease in children.

Sinus disease in children is usually ethmoidal in location. Acute illness is common and responds well to antibiotics. Sometimes the infection causes ipsilateral orbital cellulitis or rarely an orbital abscess. Systemic administration of antibiotics is usually effective in bringing about resolution. Surgery is not often needed. Acute maxillary sinus disease occurs more often in the older child in the second decade of life. It is manifested by pain in the cheek and teeth, nasal obstruction, and discharge. Treatment with antibiotics is usually effective. For chronic illness, irrigations in most cases bring about resolution. However, occasionally Caldwell-Luc surgery may be necessary.

Salivary gland involvement in systemic diseases.

The salivary glands participate in systemic illnesses because they are secretory structures allied with the gastrointestinal tract. Thus they are involved in systemic inflammatory, allergic, and neoplastic conditions. Perhaps the most common condition is that of mumps in the acute phase. Of the chronic diseases, Mikulicz's disease or Sjögren's syndrome is most frequently noted. In most instances of systemic involvement, the salivary gland enlargement is the rule, with the gland being tense, soft, and enlarged, and with progressive growth over a period of time. Usually all glands are involved. The diagnosis should be suspected from the history and the physical examination, noting that all the glands are equally involved by the enlargement. If there is any question, a biopsy should be performed. In the case of Sjögren's syndrome, the biopsy specimen may be taken either from a major salivary gland or from one of the minor ones, or the nasal mucous membrane or oral cavity. In general, definitive therapy is unsuccessful for the systemic illness involving the salivary glands, and in most instances has to be supportive.

Intracranial and extracranial nasopharyngeal angiofibroma. A surgical approach.

Two patients with juvenile nasopharyngeal angiofibromas with known or suspected intracranial extension were treated successfully with a surgical procedure. The procedure involves careful preoperative examination with four-vessel carotid angiography followed by preoperative occlusion of the extracranial major feeding vessels. This is followed by craniotomy, direct control of all intracranial feeding vessels, and then total extirpation of the tumor.

Adenotonsillectomy in a Jehovah's Witness with blood dyscrasia.

A case is used to illustrate a method of management of three unusual problems all simultaneously appearing in the same patient. Urgent surgical intervention was necessary for a child with a bleeding disorder, but the parents religious doctrine prohibited the use of whole blood or its products. The combined efforts of the legal, medical, and allied medical professionals led to a successful resolution of the patient's multiple problems.
