Stress, burnout and hardiness in R.T.s

This article reports results of a survey assessing the relationship among occupational stress, "personality hardiness" and burnout in 95 radiographers employed in Connecticut hospitals. Regression analyses indicated a positive correlation between burnout and occupational stress, and an inverse relationship between personality hardiness and burnout. Personality hardiness had a beneficial effect at all stress levels.     

Impact of tonsillectomy and adenoidectomy on child behavior

OBJECTIVE: To measure the impact of tonsillectomy and adenoidectomy (T&A) on children's behavioral and emotional problems using a standardized assessment. DESIGN: Prospective study. SETTING: Tertiary care children's hospital. PATIENTS: Thirty-six children, aged 2 through 18 years, with symptoms of nighttime snoring, observed apneas, and daytime mouth breathing and physical examination results demonstrating 3+ or 4+ tonsils scheduled for T&A. INTERVENTION: Parents completed a standard survey of their children's symptoms of sleep apnea and a standardized measure of children's competencies and problems, the Child Behavior Checklist for ages 2 through 3 years or 4 through 18 years, before T&A and 3 months postoperatively. MAIN OUTCOME MEASURE: The Child Behavior Checklist total problem score. RESULTS: The preoperative Child Behavior Checklist total problem score was consistent with abnormal behavior for 10 children (28%). After T&A (n = 15), only 2 scores were abnormal, but the change was not statistically significant. In contrast, the mean total problem score was 7.5 points lower after surgery (95% confidence interval, 5.1-9.7), indicating a significant decrease (P<.001, matched t test). CONCLUSIONS: This pilot study demonstrates a high prevalence (28%) of abnormal behavior in children undergoing T&A for chronic upper airway obstruction. Scores on a standardized measure of behavior improve following T&A, but larger studies with increased statistical power are needed to clarify the degree of improvement and its clinical importance.     

Gingko biloba (Rökan) therapy in tinnitus patients and measurable interactions between tinnitus and vestibular disturbances

Tinnitus is one of the most important symptoms in neurootology after vertigo, nausea, and hearing loss. In most cases, the origin of the tinnitus remains inexplicable. Well-known, however, is that tinnitus may arise in any part of the hearing pathway (i.e., both within the cochlea receptor and in the temporal lobe and projections). Tinnitus also is associated frequently with vertigo, nausea and hearing loss. An age predominance exists, with tinnitus more common among those older than 40 years. From this starting point, a great demand exists today for new ideas and developments in the diagnosis and treatment of tinnitus.     

Cystic fibrosis patients with and without central nervous system complications following lung transplantation

Central nervous system (CNS) complications occur more frequently in cystic fibrosis (CF) patients than other lung transplant recipients. The purpose of this study was to compare CF patients with and without CNS complications following lung transplantation, to identify risk factors for CNS events. Records of 21 patients with CF who underwent lung transplant between 1991-1996 were reviewed. Data were collected on multiple variables, including: age at transplant; gender; cytomegalovirus (CMV) status; cholesterol and triglyceride levels; sinusitis; percent ideal body weight (IBW); body mass index (BMI); augmented immunosuppression, acute lung rejection episodes (ALR); cyclosporine doses; electrolytes; magnesium, blood urea nitrogen (BUN), and creatinine levels; and 6-month survival. CNS complications identified were seizures, severe headaches (HA), strokes, or confusional episodes. Eleven of 21 patients (52%) with CF had CNS events: eight had seizures, five HA, three strokes, and one confusional episode. There was no difference in age at transplant, pretransplant percent IBW or BMI, cholesterol and triglyceride levels, or number of ALR. CMV mismatch and clinical sinusitis had no effect. Cyclosporine doses did not differ between groups at 30 days, or 3 or 6 months posttransplant. Both BUN and creatinine concentrations showed a rise over time that did not differ between groups. Potassium levels were within normal limits for both groups. While sodium levels did not differ between groups pretransplant, or at 30 days or 6 months posttransplant, a decrease in sodium values was seen at the time of CNS events. There was no difference in 6-month survival. We could not identify any pre- or posttransplant risk factors that predicted CNS events. It is likely that cyclosporine toxicity is the major cause of CNS complications. Despite the high rate of CNS events, the overall prognosis was good, and 6-month survival was not affected.     

Autologous hemopoietic stem-cell transplantation for children with refractory autoimmune disease

Autologous stem cell transplantation (ASCT) has been proposed as a possible treatment for severe autoimmune diseases such as rheumatoid arthritis (RA), multiple sclerosis (MS), systemic sclerosis, and systemic lupus erythematosus (SLE). To date, more than 250 patients with various autoimmune disorders have undergone an ASCT since 1996. Among them, there is a very limited number of children. This review summarizes the experience with ASCT for pediatric rheumatic diseases. Most reported cases concern juvenile idiopathic arthritis (JIA). Experience with ASCT for childhood SLE, Scleroderma, or Dermatomyositis is very limited. To date, 12 children with severe systemic or polyarticular JIA, all with progressive disease activity despite the use of corticosteroids, MTX, CsA, or Cyclophosphamide were treated in our center with ASCT. Rheumatologic follow-up at 3-month intervals up to 36 months showed a marked decrease in arthritis severity as expressed by the core-set criteria for juvenile chronic arthritis (JCA) activity. However, these children remain at risk for severe viral infections due to the prolonged lymfopenia. ASCT in this severely ill patient group induces a very significant and drug-free remission of the disease, but carries a significantly risk of developing fatal MAS.
