Sixty four patients were referred for cardiac transplantation from a single cardiac team at this hospital between October 1984 and December 1986. Of these patients, 33 were referred for urgent transplantation, all of whom required intensive treatment in hospital with intravenous infusions of cardiac drugs, intra-aortic balloon counterpulsation, peritoneal dialysis, ventilation, or any combination of these to sustain life. Of these 33 patients, six died while awaiting transplantation, one was removed from the waiting list for a transplant, and 26 received cardiac transplants. There were five deaths within 24 hours of operation and one death 10 days after the operation. Twenty of those who had surgery had a successful outcome of transplantation, but there was one late death 10 weeks postoperatively and a further death 31 months after surgery. Eighteen patients were alive and well 10 to 33 months (mean 19·4 months) after transplantation, with an overall survival rate after surgery of 69%.Provided that surgery can be performed before renal failure has progressed such that renal transplantation is necessary, the results are excellent (surgical survival 85·5%) and, we believe, justify the expenditure and staffing requirements necessary to treat these terminally ill patients. 相似文献

Intensive treatment for newborns with trisomy 13 is controversial because of their lethal prognosis. We report the better life prognosis of patients with trisomy 13 who received intensive treatment. At our hospital, we provided an intensive management to such patients including resuscitation and surgical procedures as required. Herein, we present the results of a retrospective study (1989-2010) of 16 trisomy 13 cases who received an intensive treatment. None was diagnosed to have trisomy 13 before birth; 9 were delivered by C-section and oxygen was administered to all patients during postpartum resuscitation. Mechanical ventilation was used in 9 patients after tracheal intubation and tracheotomy was performed in 2 patients when withdrawing of extubation was difficult. Regarding prognosis, 9 patients died, 3 were referred to another hospital, and 4 were discharged from the hospital. Four and 7 patients died within 7 and 30 days after birth, respectively. Nine patients survived for >1 month, 7 for >180 days, and 5 for >3 years. Median survival for 16 patients was 733 days. The patients who received intensive treatments survived longer compared to the previous data. This study provides useful information concerning genetic counseling, especially from an ethical point of view, before providing intensive management to newborns with trisomy 13. 相似文献

The molecular basis of the pathogenesis of pulmonary hypertension (PH) associated with congenital diaphragmatic hernia (CDH)
is poorly understood. Variation in responses to therapeutic strategies such as nitric oxide (NO) inhalation and extracorporeal
membrane oxygenation (ECMO) in patients with CDH remains a major problem in pediatric critical care. We investigated the expression
pattern of NO-generating enzyme nitricoxide synthase (NOS) (both endothelial [eNOS] and inducible [iNOS] isoforms) in the
lungs of CDH patients with PH and evaluated the influence of ECMO on the expression levels of these genes in an attempt to
understand the underlying molecular mechanisms. Lung autopsy specimens from 23 cases of CDH not treated by ECMO and 10 ECMO-treated
CDH cases were studied and compared with 11 age-matched controls. Expression of iNOS and eNOS was assessed by immunohistochemistry
and video-image analysis. Expression of iNOS in the endothelium of small pulmonary arteries (external diameter≤200 μm) was
significantly lower in CDH cases that had not received ECMO treatment (p=0.04). ECMO-treated CDH cases did not differ from controls in iNOS expression. Alveclar macrophages (CD68+ cells), of which the number also was increased, showed significantly enhanced staining for iNOS in CDH cases (p=0.03) compared with controls. The observed decrease in pulmonary expression of iNOS in patients with CDH suggests a potential
role in the pathogenesis of pulmonary hypertension in newborns with CDH. ECMO treatment was correlated with induction of this
enzyme, which may result in NO-mediated vasodilatation and thereby transiently reduce the pulmonary hypertension in CDH. 相似文献

A retrospective analysis of 62 patients with 78 congenital dislocations of the hip (CDH) referred to Children''s Hospital at Stanford was done to ascertain whether CDH was being diagnosed as early as had been thought possible and whether various treatments were effective. In this series there were a substantial number of cases of CDH that were not diagnosed within the first 48 hours of life. At Children''s Hospital the Pavlik harness was the most effective form of treatment of congenital dislocations of the hip in the perinatal period. 相似文献

The survival and neurodevelopmental outcome of 356 extremely preterm infants born at 23 to 28 weeks'' gestation were reported by week of gestation. Their corrected 1 year survival improved from 7% at 23 weeks to 75% at 28 weeks. The overall incidence of impairment was 19% and of major disability 12%. Boys had a significantly lower normal survival than girls. Multiple births had a significantly lower survival and higher incidence of impairment than singleton births. Predictions of outcome were made before delivery, after resuscitation, and at 1 week to aid the development of guidelines on when perinatal intensive care is justified, whether obstetric intervention for fetal reasons is warranted, and what initial and ongoing prognoses to give to parents. Intensive care for progressively smaller and more immature infants, many of whom were previously considered non-viable, needs to be carefully monitored by every perinatal centre. 相似文献

After preliminary validation of test weighing under ward conditions the fluid intake and weight gain of 39 breast-fed and 25 artificially fed infants were compared. All were fed every four hours for six feeds a day, and the breast-fed infants received dextrose supplements only. The average intake and weight gain of the breast-fed group was significantly less than that of the group fed artificially.When cows''-milk supplements are withheld from breast-fed infants a four-hourly regimen provides insufficient stimulus to lactation for their needs in the first week of life. If more than lip service is to be paid to the mother who desires to breast-feed in hospital, early and more frequent feeding should be practised. 相似文献

BACKGROUND: Congenital diaphragmatic hernia (CDH) is a severe birth defect where there is an opening in the diaphragm through which a portion of the abdominal contents protrudes into the thoracic cavity. The etiologies of CDH remain unknown, although experimental animal data suggest dietary factors might play a role. This study examined whether maternal nutrient intakes were associated with delivering infants with CDH. METHODS: We analyzed infants with isolated CDH who were born from 1997 to 2003 and recruited into the National Birth Defects Prevention Study (NBDPS), a multisite, population‐based case‐control study. Exposure data were obtained from telephone interviews, which were completed within 24 months after delivery, and were available for 377 case mothers and 5,008 control mothers. A food frequency questionnaire was used to derive nutrient intakes during the year before pregnancy. RESULTS: A crude OR of 0.6 (95% CI: 0.3–1.0) was observed for higher intake of choline. Elevated ORs (1.4 to 1.7) were found for lower intakes of choline, cysteine, methionine, and protein. Among women who took vitamin supplements, higher intakes of B vitamins (i.e., folate, vitamin B1, B2, B6, and B12), minerals (i.e., calcium, iron, magnesium, and zinc), and vitamin E were inversely associated with CDH (ORs from 0.7–0.3). Moreover, among women who did not take vitamin supplements, lower intakes of calcium, retinol, selenium, vitamin B12, and vitamin E had positive associations with CDH (ORs from 1.4 to 2.1). CONCLUSIONS: Our observations contribute to a limited body of evidence suggesting a woman's periconceptional diet might be associated with CDH in her offspring.

OBJECTIVE: To describe survival, disability, and morbidity after radiotherapy for malignant glioma. DESIGN: Two year prospective study with home interviews with patients and relatives. SETTING: Seven neurosurgical and radiotherapy centres in London. SUBJECTS: 105 patients aged 21 to 75: 59 had biopsy; 46 had partial macroscopic resection; 92 received radiotherapy; and 13 received steroids alone. MAIN OUTCOME MEASURES: Survival, time free from disability, and changes in disability after treatment. RESULTS: Six and 12 month survival for radiotherapy patients was 70% and 39%, respectively. Age, World Health Organisation clinical performance status, extent of surgery, and history of seizures before diagnosis each influenced survival. The Medical Research Council prognostic index was also significantly related to survival. Multivariate analysis showed that initial clinical performance status was the most important component of the index. Most (80%; 49/61) patients with a clinical performance status of 0, 1, or 2 lived at least six months before becoming permanently disabled. Most patients who had initially had a good clinical performance status (0-2) and who were alive six months after radiotherapy (68%; 36/52), however, had experienced either clinical deterioration or severe tiredness after treatment. In 17% (9/52) of these some permanent loss of function remained. These adverse effects were associated with increasing radiotherapy dose. Severely disabled patients (clinical performance status 3 or 4) gained little benefit. CONCLUSION: Severely disabled patients gain little physical benefit from radiotherapy, whereas those not so disabled may experience considerable adverse effects. 相似文献

OBJECTIVE--To evaluate the outcome of liver transplantation in patients with alcoholic cirrhosis with respect to selection criteria, survival, and evidence suggesting a return to harmful drinking. DESIGN--Nine year retrospective study. SETTING--Cambridge and King''s College Hospital liver transplant programme. SUBJECTS--24 Patients (three women, 21 men) with alcoholic cirrhosis. MAIN OUTCOME MEASURES--Survival, rehabilitation, and clinical and laboratory evidence of a return to harmful drinking after transplantation. RESULTS--15 Patients were selected for transplantation because of repeated admission to hospital for the complications of advanced portal hypertension despite abstinence, and six because they had a hepatocellular carcinoma superimposed on alcoholic cirrhosis. Three patients who were not abstinent received transplants. The one year survival rate was 66%, and of the 18 patients surviving at least three months, 17 had been rehabilitated. In three patients laboratory variables and histological examination of the liver suggested a return to drinking, though they did not admit to taking alcohol. These patients represented the only cases in the series that were not abstinent before transplantation. CONCLUSIONS--The survival and rehabilitation of patients who received transplants for alcoholic cirrhosis compared favourably with those of patients who received transplants for cirrhosis of other aetiology. The criteria for selection for liver transplantation in patients with alcoholic cirrhosis should include recurrent complications related to severe portal hypertension despite maximum medical treatment in addition to a minimum period of six months of abstinence before transplantation. 相似文献

Vasoactive prostanoids may be involved in persistent pulmonary hypertension (PPH) in infants with a congenital diaphragmatic hernia (CDH). We hypothesized that increased levels of prostanoids in bronchoalveolar lavage (BAL) fluid would predict clinical outcome. We measured the concentrations of 6-keto-prostaglandin F(1alpha) (6-keto-PGF(1alpha)), thromboxane B(2) (TxB(2)), protein, albumin, total cell count, and elastase-alpha1-proteinase-inhibitor complex in BAL fluid of 18 CDH patients and of 13 control subjects without PPH. We found different concentrations of prostanoids in BAL fluid of CDH patients with PPH: infants with a poor prognosis had either high levels of both 6-keto-PGF(1alpha) and TxB(2) compared to controls, or high levels of 6-keto-PGF(1alpha) only. TxB(2) levels showed a large variability in all CDH patients irrespective of outcome. We conclude that prostanoid levels in BAL fluid do not predict clinical outcome in CDH patients. 相似文献

OBJECTIVE: To determine the outcome and side effects of a new drug protocol to induce abortion. DESIGN: Case series. SETTING: An urban primary care practice. PATIENTS: One hundred consecutive patients who requested elective termination of pregnancies of less than 8 weeks'' gestation. INTERVENTION: Subjects received methotrexate (50 mg/m2 body surface area, administered intramuscularly) and, 3 days afterward, misoprostol (800 micrograms, given vaginally). OUTCOME MEASURES: Number of abortions induced within 24 hours and within 10 days of misoprostol administration, number of surgical aspirations conducted because of incomplete abortion, mean amount of bleeding and pain and the number of women who, if faced with the same situation, said they would again choose a drug-induced abortion over a surgical one. RESULTS: Abortion occurred within 24 hours of misoprostol administration among 48 women and within 10 days among 69 women. In total, 89 women had an abortion without surgical aspiration. Of these women, 71 said they would choose a drug-induced abortion if faced with the choice again. CONCLUSION: Abortion induced with methotrexate and misoprostol appears to be a feasible alternative to surgical abortion and deserves further study. 相似文献

OBJECTIVES: To assess the health status of patients before and after breast reduction surgery and to make comparisons with the health status of women in the general population. DESIGN: Postal questionnaire survey sent to patients before and six months after surgery. SETTING: The three plastic surgery departments in the Oxford Regional Health Authority, during April to August 1993. SUBJECTS: 166 women (over the age of 16 years) referred for breast reduction; scores from the "short form 36" (SF-36) health questionnaire completed by women in the 1991-2 Oxford healthy life survey. MAIN OUTCOME MEASURES: Health status of breast reduction patients before and after surgery as assessed by the SF-36, the 28 item general health questionnaire, and Rosenberg''s self esteem scale; comparisons between the health status of breast reduction patients and that of women in the general population; outcome of surgery as assessed retrospectively by patients. RESULTS: Differences between the health status of breast reduction patients and that of women in the general population were detected by the SF-36 both before and after surgery. Breast reduction surgery produced substantial change in patients'' physical, social, and psychological function. The proportion of cases of possible psychiatric morbidity according to the general health questionnaire fell from 41% (22/54) before surgery to 11% (6/54) six months after treatment. Eighty six per cent (50/58) of patients expressed great satisfaction with the surgical result postoperatively. CONCLUSION: The study provides empirical evidence that supports the inclusion of breast reduction surgery in NHS purchasing contracts. 相似文献

A seven-task behavioral test was performed on 86 common marmoset (Callithrix jacchus) infants, 24-36 h following birth. This report describes the test outcome and its relation to physical condition and survival of the infants. The percentage of infants receiving a perfect score on a given task ranged from 30.6 (rooting) to 70.6% (grasping). Heavier infants were more likely to have perfect scores for crawling (F=4.20, P=0.044) and infants with a longer knee-heel length tended to be more likely to have a perfect grasping score (F=3.63, P=0.06). While the modal score was a perfect score for most individual tasks, the modal number of total perfect scores that a given infant received was 3-4 and only 4.7% of infants received perfect scores on all seven tasks. These results suggest that this group of behavioral tasks will produce a variable response within a population of neonates. While no individual behavioral score predicted survival during week 1, the number of perfect scores across all tasks was predictive of survival outcome; infants with a higher total number of perfect scores were more likely to survive (F=6.02, P=0.018). When all combinations of tests were compared, the best predictor of survival was outcome on four of the seven tests, all related to motor skills (F=7.46, P=0.009). 相似文献

Background
Hemolysis is common in all extracorporeal circuits as evident by the elevated plasma free hemoglobin (PFHb) level. We investigated whether increased hemolysis during extracorporeal membrane oxygenation (ECMO) is an independent mortality predictor.Methods
We performed a retrospective observational study of consecutive subjects who received ECMO at a tertiary care facility from 2007-2013 to investigate independent predictors of in-hospital mortality. We examined variables related to patient demographics, comorbidities, markers of hemolysis, ECMO characteristics, transfusion requirements, and complications. 24-hour PFHb> 50 mg/dL was used as a marker of severe hemolysis.Results
154 patients received ECMO for cardiac (n= 115) or pulmonary (n=39) indications. Patients’ mean age was 51 years and 75.3% were males. Compared to nonsurvivors, survivors had lower pre-ECMO lactic acid (p=0.026), lower 24-hour lactic acid (p=0.023), shorter ECMO duration (P=0.01), fewer RBC transfusions on ECMO (p=0.008) and lower level of PFHb 24-hours post ECMO implantation (p=0.029). 24-hour PFHb> 50 mg/dL occurred in 3.9 % versus 15.5% of survivors and nonsurvivors, respectively, p=0.002. A Cox proportional hazard analysis identified PFHb> 50 mg/dL 24-hours post ECMO as an independent predictor of mortality (OR= 3.4, 95% confidence interval: 1.3 – 8.8, p= 0.011).Conclusion
PFHb> 50 mg/dL checked 24-hour post ECMO implantation is a useful tool to predict mortality. We propose the routine checking of PFHb 24-hours after ECMO initiation for early identification and treatment of the cause of hemolysis. 相似文献15.

In a retrospective analysis the records of all (210) infants ventilated to treat the respiratory distress syndrome over three years were reviewed. A mortality of 19% was found. Intraventricular haemorrhage was associated than a significant increase in mortality in infants of less with 30 weeks'' gestation (p less than 0.001) and was the commonest cause of death. Pneumothoraces developed in one third of babies regardless of gestational age but were significantly associated with an increase in mortality only in infants of 27-29 weeks'' gestation. Patent ductus arteriosus was present in 31 infants and was commoner in babies of very low birth weight. The presence of a patent ductus arteriosus was not associated with decreased survival but was significantly related to an increased need for prolonged respiratory support (p less than 0.001). Thirty six infants developed chronic lung disease, three of whom died. Comparison with data from earlier studies indicated a steady improvement over the past decade in outcome for infants ventilated for the respiratory distress syndrome. 相似文献

OBJECTIVE--To assess the morbidity and mortality associated with a prenatal diagnosis of bilateral fetal uropathy. DESIGN--Retrospective study. SETTING--Departments of radiology, paediatric surgery, obstetrics, and pathology in two teaching hospitals that serve as referral centres for the Yorkshire region. PATIENTS--126 Cases of fetal uropathy were referred either prenatally or postnatally from hospitals in Yorkshire between August 1982 and December 1987. The disease was bilateral in 54 cases and unilateral in 72 cases. In 14 cases bilateral fetal uropathy was associated with coexistent disease. INTERVENTIONS--All cases were managed individually by an obstetrician after discussion with the radiologists and paediatric surgeons. Babies who survived were treated prophylactically with antibiotics after delivery and were operated on if appropriate. END POINT--Assessment of prognosis for long term renal function for each baby referred between August 1982 and December 1987: follow up ranged from six months to five years. MEASUREMENTS AND MAIN RESULTS--Of the 54 fetuses with bilateral fetal uropathy, 13 were terminated as the prenatal findings of ultrasonography were considered to be incompatible with long term survival. Ten of the liveborn babies died, five of renal or pulmonary insufficiency, or both, and five of associated congenital anomalies. Thirty one infants survived to follow up; four of these had serious coexistent disease and two had impaired renal function. Thus the overall mortality was 43% and the morbidity rate 19%. The renal anomaly was associated with other serious disease in 14 cases (26%) compared with two (3%) of the 72 cases of unilateral fetal uropathy. All but two of the 27 infants with isolated bilateral urinary tract disease had excellent prospects for survival. CONCLUSION--Although bilateral fetal uropathy is associated with a high morbidity rate and mortality, careful prenatal assessment can help to identify fetuses with a poor prognosis. The outlook for a fetus with isolated renal disease if treated promptly after delivery is excellent and compares favourably with that reported after prenatal surgical intervention. 相似文献

Incisional sustained tachycardias are frequent in patients who have undergone a surgical repair of interatrial defect. A 43-year-old woman with drug refractory, highly symptomatic, persistent atrial tachycardia in the last year, was referred to our unit for catheter ablation. The patient had undergone a cardiac operation for repairing interatrial secundum ostium type defect with a patch five years before. A previous radiofrequency ablation procedure had been performed for common atrial flutter. We describe a case of incisional atrial tachycardia ablation guided by the new EnSite NavX system equipped with a new electroanatomic mapping system. 相似文献

In a study of all 4275 outpatient consultations over one month in a district general hospital it was found that the clinics in surgical specialties had the largest numbers of patients. In general surgery less than half of new patients and only one third of all patients attending the clinic were seen by a consultant. (Nine months later about a third of all new patients had still not seen a consultant in the clinic.) In the medical clinics just over a quarter of patients were seen by doctors who had less than six months'' experience in their present specialty after registration. Overall, doctors had been on continuous duty for at least 24 hours before a third of consultations. Doctors in training had actually worked during the previous night before attending a quarter of the clinics.Much of the large volume of work is performed by tired, incompletely trained doctors. It is suggested that a greater proportion of the work should be performed by fully trained staff. The workload might be reduced by modifying the pattern of the consultation. 相似文献

OBJECTIVE--To assess the relations between early introduction of solid food and infant weight, gastrointestinal illness, and allergic illnesses during the first two years of life. DESIGN--Prospective observational study of infants followed up for 24 months after birth. SETTING--Community setting in Dundee. PATIENTS--671 newborn infants, of whom 455 were still available for study at 2 years of age. MAIN OUTCOME MEASURES--Infants'' diet, weight, and incidence of gastrointestinal illness, respiratory illness, napkin dermatitis, and eczema at 2 weeks and 2, 3, 4, 6, 9, 12, 15, 18, 21, and 24 months of age. RESULTS--The infants given solid food at an early age (at < 8 weeks or 8-12 weeks) were heavier than those introduced to solids later (after 12 weeks) at 4, 8, 13, and 26 weeks of age (p < 0.01) but not at 52 and 104 weeks. At their first solid feed those given solids early were heavier than infants of similar age who had not yet received solids. The incidence of gastrointestinal illness, wheeze, and nappy dermatitis was not related to early introduction of solids. There was a significant but less than twofold increase in respiratory illness at 14-26 weeks of age and persistent cough at 14-26 and 27-39 weeks of age among the infants given solids early. The incidence of eczema was increased in the infants who received solids at 8-12 weeks of age. CONCLUSION--Early introduction of solid food to infants is less harmful than was previously reported. Longer follow up is needed, but, meanwhile, a more relaxed approach to early feeding with solids should be considered. 相似文献
