Gastrointestinal teratomas are uncommon, benign neoplasms that occur primarily in children. A retrospective review of five cases (two gastric, one pancreatic, one mesenteric, and one in the lesser omentum) is presented with emphasis on the computed tomographic and ultrasonographic appearances. Principal findings are a well-defined mass with separate cystic and solid components of varying proportions, discrete areas with densities similar to that of fat, or coarse, globular calcifications within the solid component. Recognition of these findings may allow the radiologist to make a correct preoperative diagnosis of teratoma. 相似文献

Intrauterine spermatic cord torsion in the newborn: sonographic and pathologic correlation 总被引:2,自引:0,他引:2
In five newborn patients with spermatic cord torsion, sonography demonstrated an enlarged and globular testis, hydrocele, and skin thickening. In four of these patients the testicular parenchyma was heterogeneous. Peripheral hypoechoic areas were seen in two of the four patients; the other two had a central hypoechoic region and a peripheral echogenic rim. The testis in the fifth patient was diffusely hyperechoic. Duplex Doppler sonography performed in two patients failed to demonstrate any signal in the spermatic cord in either the abnormal or contralateral hemiscrotum. Scintigraphic findings were positive for testicular torsion in two patients and equivocal in three patients. Surgery was performed 2-12 days after sonography and established the diagnosis of spermatic cord torsion. Pathologic examination demonstrated hemorrhagic infarction of the entire testis as well as scattered calcifications. The authors conclude that a solid globular testicular mass seen during the neonatal period is suggestive of intrauterine spermatic cord torsion. 相似文献

Cholesteatomas, arising within the middle ear space behind an intact tympanic membrane, have been detected more frequently in recent years. This article reviews 19 children (with a mean age of 4.3 years) who underwent surgery over a 7-year period for removal of cholesteatomas from behind intact tympanic membranes. Most of these children were referred by pediatricians who had detected an asymptomatic whitish middle ear mass. Many had histories of treatment for otitis media. Patients with similar histories were excluded from the series if there had been a prior perforation, myringotomy, or otologic surgery. In the series, one fourth of the children had associated congenital malformations, and there were 3 times as many boys as girls. In two thirds of the cases, the cholesteatoma was manifested as an anterior-superior middle ear mass that seemed to arise from the processus cochleariformis, undersurface of malleus area. Many could be removed via an extended anterior tympanotomy operative approach. The results of surgery are reviewed. The possible origins of these localized cholesteatomas are considered. Are they congenital defects that arise from misplaced keratinizing epithelium? Do they arise from mesenchymal cells whose differentiation is stimulated by inflammatory changes within the middle ear? 相似文献

This review of recent literature explores the similarities and differences between the work of community psychiatric nurses and their mental handicap counterparts. The comparisons which have been made between groups of nurses are related to the authors own research studies. These included an observations study of one community mental handicap nursing team and a national survey of all such teams in England and Wales. The importance of trade union membership, the place of the Community Psychiatric Nursing Association and the implication of joint training courses are discussed. The emergence of a new professional role that of the 'community mental health nurse' is discussed and the implications which this might have for the future organization of community psychiatric nursing services is outlined. 相似文献

Sense of coherence among elderly somatic patients: predictive power regarding future needs of care 总被引:2,自引:0,他引:2

The main aim was to study the predictive power of sense of coherence regarding future needs of care among elderly patients evaluated as medically ready for discharge from somatic emergency care. A secondary aim was to study the consistency of sense of coherence over time among patients with this kind of experience. The sample consisted of 53 Swedish patients (mean age 82.8 years, SD = 6.6 years) who had completed their medical treatment at surgical or orthopaedic departments. The predominant diagnosis was lower limb fractures. Sense of coherence was assessed twice, on the day the patient was evaluated as medically ready for discharge and 1 month later. On the second assessment occasion, 28 patients had returned to their homes, 17 were staying at institutions, and eight had died. Patients who returned to their homes reported the strongest sense of coherence while still in hospital. Patients who were staying at institutions scored lowest on the overall sense of coherence scale and on the comprehensibility subscale. Patients who died before the second measurement occasion scored lowest on the meaningfulness subscale. A correlation of 0.51 was noted between the two assessments of sense of coherence, indicating a moderate temporal consistency. 相似文献

In the community, acute hypoglycaemia is commonly caused by therapies for
diabetes mellitus or the excessive consumption of alcohol. Although most
episodes do not require admission to hospital, little information is
available on the causes and outcome of those that do. We retrospectively
surveyed adult patients admitted to a large urban teaching hospital with
acute hypoglycaemia in a 12-month period, identifying 56 admissions of 51
patients. Forty-one had diabetes mellitus, 33 (80%) of whom were receiving
treatment with insulin. The others had hypoglycaemia induced by excessive
consumption of alcohol or by deliberate self-poisoning with insulin. A
history of psychiatric illness and/or chronic alcoholism was common.
Neurological manifestations of hypoglycaemia were the principal reason for
admission, observed on 50 occasions (89%), and 11 events (20%) had
precipitated convulsions. Although many patients (59%) had received
treatment for hypoglycaemia before admission, hypoglycaemia recurred in 16%
of patients in hospital. Four patients (7%) died following admission, but
in only one case was this the direct result of hypoglycaemia. However,
within 15 months of the index hypoglycaemia event, a further six patients
(11%) had died, mostly of causes unrelated to hypoglycaemia. Patients who
require hospital admission for treatment of hypoglycaemia have a high
incidence of neurological manifestations, a high rate of mental illness and
other medical disorders, and may represent a high-risk subgroup with a poor
long-term prognosis.
