Submandibular hydatid cyst caused by Echinococcus oligarthrus.
An unusual case of Echinococcus oligarthrus infestation of the submandibular salivary gland is reported. Echinococcus oligarthrus is a rare variant of the Echinococcus species affecting humans. To the best of our knowledge only one case of submandibular hydatid cyst caused by Echinococcus oligarthrus has been reported. A 28-year-old female patient was admitted with a progressively increasing swelling in the left submandibular region of four years' duration. There was no pulmonary or hepatic involvement. The present case of submandibular hydatid cyst caused by Echinococcus oligarthrus is of interest because of the unusual site of the disease.
Role of polysomnography in tracheostomy decannulation in the paediatric patient.
Tracheostomy in infants and children has been the subject of controversy in the medical literature, but decannulation in the paediatric patient is even more controversial. Various approaches and techniques have been used for decannulation, however in spite of all efforts it continues to be a problem. The objective of our study was to assess the role of polysomnography (PSG) in predicting readiness for decannulation. All subjects (n = 31) of the study were less than 12 years of age, and tracheostomized for periods of at least six months to ensure a minimum period of dependence on the tube. All had clinical, radiological and endoscopic clearance before PSG was performed. Twenty-one out of 22 patients with favourable PSG data were successfully decannulated. Attempts to decannulate all the nine patients with unfavourable PSG failed. The conclusion of the study was that PSG is a useful adjunct to the many methods of evaluating readiness for decannulation in children with long-term tracheostomy tubes.
Tympanoplasty in children--a prospective study.
Considerable controversy surrounds the subject of tympanoplasty in children. This prospective study looked at the results of type-I tympanoplasty in children. Forty-five children in the age group of five to 14 years were selected for the study. All these cases had a central perforation without any evidence of cholesteatoma. The ear to be operated had to be dry for at least six weeks before surgery. Type I tympanoplasty was performed on these patients with autograft temporalis fascia by either the underlay or overlay technique. The overall success rates in 45 operations evaluated one year post-operatively was 91.1 per cent. The age of the patient had no influence on the success rate. The two factors which adversely influenced the success rate were the presence of near total perforation and bilateral perforations. It was concluded that type-I tympanoplasty has a good chance of success in children regardless of age.
Two unusual cases of foreign body larynx.
Two adult patients of foreign body larynx who presented to us with a short history of foreign body inhalation with severe respiratory distress are being reported. They underwent elective tracheostomy preoperatively for maintenance of airway and the foreign body was removed successfully. We conclude that preoperative tracheostomy can be attempted to secure a patient's airway before resorting to removal of foreign body lodged in the larynx.
