After ingesting or inhaling laundry detergent powder, eight children required hospital admission. The predominant symptoms were stridor, drooling, and respiratory distress. All but one patient underwent endoscopy of the airways and the esophagus, five children were admitted to the intensive care unit, and four children required endotracheal intubation. Laundry detergent ingestions are generally considered to have minor consequences, and there exists a paucity of literature on the subject. Evidence of significant morbidity incurred because of ingestion or inhalation of sodium carbonate-containing laundry detergent powder is presented, together with a review of the existing literature.  相似文献

Twenty two patients (age range: 1 month to 11 years) were treated for congenital diaphragmatic defects (excluding hiatus hernia) in the six year period 1983-8. Presenting features were failure to thrive (n = 7), abdominal pain and vomiting (n = 4), chronic respiratory symptoms (n = 3), and inability to wean from ventilatory support (n = 3). The defect was an incidental finding in five patients. Operative repair was performed with no mortality or serious postoperative morbidity. Dramatic improvement occurred in 15 of the 17 symptomatic patients. Awareness of the differential diagnosis should avoid delay in diagnosis or inappropriate treatment. Surgical correction is strongly recommended in all cases.  相似文献

Free microvascular anastomosed tissue transfer has improved the reconstruction of soft tissue defects dramatically. For reconstruction of facial and cervical soft tissue defects numerous free flaps are available to the head and neck surgeon, however, most of the reconstructive problems can be solved by using a limited number of reliable and versatile techniques. In microvascular tissue transfer, the scapular flap offers similar advantages as to reliability and versatility as the pectoralis major flap in pedicled tissue transfer. In contrast to the scapular flap the groin flap is more bulky, its skin is soft and may carry pubic hair on its medial aspect. After partial maxillectomy or in facial dysplasia facial contour may be restored satisfactory with a completely or partially de-epithelialized scapular flap. In total hypopharyngeal and cervicoesophageal defects the jejunum transplant provides an ideal tubular replacement. If after resection of an intraoral carcinoma with partial mandibulectomy an osteocutaneous transfer has to be achieved the mandibular defect may be reconstructed with bone from the iliac crest or from the radius while the intra- and extraoral tissue defect may be closed with the adjacent skin flaps. For the closure of large penetrating defects of the cheek the inferior epigastric abdominal wall flap in particular has proved a versatile and reliable flap. This flap offers both, a cutaneous and a peritoneal surface. Latter is used for the replacement of the intraoral lining.  相似文献

The question of the necessity of in-patient facilities of the area of (child and) adolescent neuropsychiatry is to be discussed further. The extremely optimistic views on this question of approximately 20 years ago cannot be maintained for the examined area and the examination time. In the LNKH Valduna/Vorarlberg, an establishment that was intended exclusively for adults until 1987, from 1980-1984 (evaluated in detail) and from 1984-1987 a further 60 minors were admitted. The exact evaluation shows that the conspicuousnesses of behaviour of a main group was so clear each time that it could not be treated elsewhere and certainly not in outpatient facilities. In the examined group the amount of patients with behaviour and socialization disorders outweighed by far the psychoses, also a high percentage of patients was multi morbid and/or had multiple handicaps. The resulting conclusion seems to us to be the necessity of setting-up a specific in-patients treatment unit for this group of patients with sufficient infrastructure.  相似文献

The incidence and mortality of acute epiglottitis were retrospectively analysed covering a 12-year period, 1975-1987. The diagnosis was made by the laryngoscopic findings in 95% of patients. Based on 902 hospitalized patients, a mean annual incidence of 4.9 cases per 100,000 children and adults was found. Although adult patients predominated (60%), the incidence was far higher in children, 13.8 per 100,000 compared with 3.9 per 100,000 in adults. Two peaks in incidence were identified, one for the youngest children, and the second for young adults (15-29 years). Over the years the incidence varied little in adults, but decreased significantly in children over the last 6 years studied. The data presented indicate acute epiglottitis to be a more frequent disorder than previously believed but with less risk of a fatal outcome. The mortality rate was below 1% in children and adults and the annual incidence of death from acute epiglottitis was estimated at 0.5 cases per million. The primary admission of these patients to ENT units seems to be the single factor having the most powerful impact on mortality.  相似文献

Tumor material from 91 patients with squamous cell carcinoma of the head and neck was transplanted subcutaneously in athymic nude mice. In the first (man to mouse) passage, the calculated mean probability of tumor take in a single mouse was 11%. The probability of growth in the first passage was significantly better for moderately and poorly differentiated tumors than for well-differentiated tumors. Also, the implantation of lymph node material resulted in a significantly better tumor take rate than material taken from a primary tumor. Transplantability was not dependent on the following characteristics: localization, T or N stage of the tumor, or the sex of the patients. Once growth was established, all variables studied had no influence on the probability of growth in the subsequent mouse passages. A relationship between tumor growth in nude mice and patient prognosis could not be found. When transplanting head and neck squamous cell carcinoma in nude mice, it has to be recognized that some tumor characteristics will influence the success of tumor growth.  相似文献
