PURPOSE: Although p53 mutations occur in alkylating agent-related leukemias, their frequency and spectrum in leukemias after ovarian cancer have not been addressed. The purpose of this study was to examine p53 mutations in leukemias after ovarian cancer, for which treatment with platinum analogues was widely used. EXPERIMENTAL DESIGN: Adequate leukemic or dysplastic cells were available in 17 of 82 cases of leukemia or myelodysplastic syndrome that occurred in a multicenter, population-based cohort of 23,170 women with ovarian cancer. Eleven of the 17 received platinum compounds and other alkylating agents with or without DNA topoisomerase II inhibitors and/or radiation. Six received other alkylating agents, in one case, with radiation. Genomic DNA was extracted and p53 exons 5, 6, 7, and 8 were amplified by PCR. Mutations and loss of heterozygosity were analyzed on the WAVE instrument (Transgenomic) followed by selected analysis by sequencing. RESULTS: Eleven p53 mutations involving all four exons studied and one polymorphism were identified. Genomic DNA analyses were consistent with loss of heterozygosity for four of the mutations. The 11 mutations occurred in 9 cases, such that 6 of 11 leukemias after platinum-based regimens (55%) and 3 of 6 leukemias after other treatments (50%) contained p53 mutations. Two leukemias that occurred after treatment with platinum analogues contained two mutations. Among eight mutations in leukemias after treatment with platinum analogues, there were four G-to-A transitions and one G-to-C transversion. CONCLUSIONS: p53 mutations are common in leukemia and myelodysplastic syndrome after multiagent therapy for ovarian cancer. The propensity for G-to-A transitions may reflect specific DNA damage in leukemias after treatment with platinum analogues.  相似文献

The aim of this investigation was to evaluate orthodontic treatment need and patient satisfaction among young adults living in a city where free-of-charge orthodontic treatment was provided. A total of 281 18- to 19-year-old subjects randomly selected from the population register of the city of Vantaa took part in the study. The drop-out rate was 30%. Treatment need was clinically assessed according to the Index of Orthodontic Treatment Need (IOTN), consisting of a Dental Health Component (DHC) and an Aesthetic Component (AC). Information on previous orthodontic treatment was based on the patient records. Satisfaction of the subjects with their dental appearance and with the orthodontic treatment received was obtained using a questionnaire. The rate of orthodontic treatment among the subjects was 46% (54% for the females and 37% for the males, p < 0.05). 4% had discontinued treatment. A definite need for treatment (DHC 4 to 5/AC 8 to 10) was assessed in 15% of the subjects, and borderline/moderate need (DHC 3/AC 5 to 7) in 36%. No difference in IOTN scores between the treated and untreated subjects was found. Females had significantly more often no treatment need (DHC 1 to 2/AC 1 to 4) compared with males (p < 0.05). The majority of subjects (89%) reported that they were very or quite satisfied with their dental appearance. The odds of being satisfied were significantly higher for the treated subjects (OR = 2.71, p < 0.05) and lower for those at the non-attractive end of the AC scale (OR = 0.14, p < 0.01). Neither gender nor DHC grade significantly affected the odds of being satisfied among the subjects. The results indicate that the majority of young adults in this study were satisfied with their dental appearance regardless of objective treatment need of various degrees. The high treatment rate in relation to unnoticed treatment need calls for reevaluation of priorities in patient selection. Zusammenfassung: Ziel dieser Untersuchung war es, den kieferorthopädischen Behandlungsbedarf und die Zufriedenheit junger Erwachsener zu bewerten, die in einer Stadt leben, in der eine kostenlose kieferorthopädische Behandlung angeboten wurde. Insgesamt nahmen an dieser Studie 281 18- bis 19-jährige Personen teil, die nach dem Zufallsprinzip aus dem Bevölkerungsverzeichnis der Stadt Vantaa ausgewählt wurden. Die Ausfallsrate betrug 30%. Der Behandlungsbedarf wurde gemäß dem "Index of Orthodontic Treatment Need" (IOTN) bewertet, der sich aus dem "Dental Health Component" (DHC) und einem "Aesthetic Component" (AC) zusammensetzt. Anamnestische Daten der Patienten gaben Aufschluss über eine vorangegangene kieferorthopädische Behandlung. Die Zufriedenheit der Personen mit dem ästhetischen Erscheinungsbild ihrer Zähne und mit der kieferorthopädischen Behandlung wurde mittels eines Fragebogens festgestellt. Der Anteil der Personen mit kieferorthopädischer Behandlung betrug 46% (54% Frauen und 37% Männer, p < 0,05). 4% hatten die Behandlung abgebrochen. Ein eindeutiger Behandlungsbedarf (DHC 4 bis 5/AC 8 bis 10) wurde bei 15% der Untersuchten festgestellt, ein grenzwertiger/mäßiger Behandlungsbedarf (DHC 3/AC 5 bis 7) bestand bei 36%. Bei den behandelten und unbehandelten Personen stellte man keinen Unterschied bei den IOTN-Kriterien fest. Bei Frauen bestand wesentlich seltener Behandlungsbedarf (DHC 1 bis 2/AC 1 bis 4) als bei Männern (p < 0,05). Die Mehrheit der Untersuchten (89%) sagte aus, dass sie mit dem ästhetischen Erscheinungsbild ihrer Zähne sehr oder ziemlich zufrieden wären. Die Zufriedenheitsrate war bei den behandelten Personen deutlich höher (OR = 2,71, p < 0,05) und niedriger bei denen, die am unattraktiven Ende der AC-Skala standen (OR = 0,14, p < 0,01). Weder das Geschlecht noch der DHC-Grad beeinflusste signifikant die Zufriedenheitsrate der Untersuchten. Das Ergebnis deutet darauf hin, dass die Mehrheit der jungen Erwachsenen dieser Studie, unabhängig von einem objektiven Behandlungsbedarf verschiedenen Ausmaßes, mit ihrer dentalen Ästhetik zufrieden war. Die hohe Behandlungsquote in Beziehung zu einem nicht begründeten Behandlungsbedarf erfordert eine Neueinschätzung der Prioritäten bei der Auswahl der Patienten.  相似文献

We describe a rare entity, superficial siderosis of the central nervous system, due to multiple small episodes of subarachnoid haemorrhage from any source. Non-specific neurological findings are associated with deposition of ironcontaining pigments in the leptomeninges and superficial layers of the cortex. T2-weighted magnetic resonance imaging demonstrates characteristic low signal in the meninges.  相似文献

PURPOSE: To perform a prospective and randomized comparison of the clinical outcome of patients with rheumatoid arthritis who had Swanson or Sutter implant replacement arthroplasty of the metacarpophalangeal joints. METHODS: There were 45 patients (3 men, 42 women) and 49 hands; a total of 75 Swanson and 99 Sutter implants were inserted. The mean time between surgery and the final follow-up control visit was 58 months (range, 37-80 mo). Preoperative and postoperative measurements were performed including active extension and flexion, correction of ulnar deviation, and strength. RESULTS: There was no statistically significant difference between groups with regard to active extension deficit correction. Mean active flexion decreased less in the Sutter group than in the Swanson group but difference between the groups was statistically significant in only the index finger. At the final follow-up examination no significant differences existed between the groups in the correction of ulnar deviation or arc of motion. Grip strengths, chuck pinch, and thump-to-fingertip grip strengths did not improve in either of the groups. CONCLUSIONS: In this study clinical results showed no significant difference between the groups with the single exception of the amount of index finger metacarpophalangeal joint flexion.  相似文献

BACKGROUND: Studies comparing socioeconomic inequalities in health using several health indicators are scarce. Therefore, this study aims to compare the shape and magnitude of occupational class inequalities across key domains of health, i.e. the subjective, functional and medical domains. Additionally, we examine whether physical or mental workload will affect these inequalities, and whether these effects are specific to particular health indicators. METHODS: Cross-sectional survey data from the Helsinki Health Study in 2000 and 2001 were used. Each year employees of the City of Helsinki, reaching 40, 45, 50, 55 and 60 years received a mailed questionnaire. 6243 employees responded (80% women, response rate 68%). The socioeconomic indicator was occupational social class. Nine health indicators were included: self-rated health, pain or ache, GHQ-12 mental well-being, limiting long-standing illness, SF-36 physical and mental health functioning, Rose angina symptoms, circulatory diseases and mental problems. Prevalence percentages, odds ratios and inequality indices from logistic regression analysis were calculated. RESULTS: Occupational class inequalities were found for self-rated health, pain or ache, limiting long-standing illness, physical health functioning, angina symptoms, and circulatory diseases. Physical or mental workload did not account for these inequalities. Inequalities were non-existent or slightly reversed for GHQ-12 mental well-being, SF-36 mental health functioning and mental problems. CONCLUSION: Expected occupational class inequalities in health among both women and men were found for global and physical health but not for mental health. The observed inequalities could not be attributed to physical or mental workload.  相似文献

We report the survival of AGC knee endoprosthesis from the Finnish Arthroplasty Register for 2 indications, osteoarthrosis (OA, 6 306 knees) and rheumatoid arthritis (RA, 2 161 knees) during 1985- 1999. Survivorship analysis was performed with revision as an endpoint. We found similar survival rates. In the OA group, survival after 5 years was 97% and it was 94% after 10 years. In the RA group the corresponding figures were 97% and 96%, respectively. There was no significant difference in survival whether or not cement was used for fixation. The revision rates were higher in men and in younger patients.  相似文献

The incidences of electrocardiographic (ECG) changes during microlaryngoscopy under halothane anaesthesia were compared by using Althesin® and thiopentone as induction agents.
During the procedure the most common ECG change in both groups was junctional rhythm, which occurred in 37% of the patients in the Althesin group and in 29% of the patients in the thiopentone group. The next most common changes in the Althesin group were: ventricular ectopic beats (22%), ischaemic S-T segment depression (14%), and T wave flattening or inversion (14%); those in the thiopentone group were ventricular ectopic beats (18%) and rapidly ascending S-T segment depression (12%). As well as during the procedure, some ECG changes were registered in both groups during intubation. ECG changes disappeared without any special treatment after manipulation of the vocal cords or after intubation.
There was no statistically significant difference in the total incidence of dysrhythmias between the Althesin and thiopentone groups, but the types of dysrhythmias were different in the two groups. There were more lower nodal rhythms, less serious ectopic beats and more ischaemic S-T segment depression in the Althesin group than in the thiopentone group.
The results suggest that Althesin is useful and superior to thiopentone in patients with a tendency to develop serious ventricular ectopic beats, whereas in patients with heart and coronary arterial disease, Althesin is inferior to thiopentone and should be used with care.  相似文献

A nine year follow up study of the delivery pattern of 119 women after delivery in the persistent occiput posterior position and their occipito-anterior controls. The studied parameters were: number of deliveries, number of repeated cases of persistent occiput posterior position and operative deliveries. Deliveries in the occipito-posterior position were more common in the study group than in the controls ( P = 0.031). Except for this, no statistically significant differences were found between the groups. According to the results, recurrence of the persistent occiput posterior position is common. A history of delivery in the persistent occiput posterior position does not seem to have any major impact on future childbearing.  相似文献

OBJECTIVE: To evaluate the longitudinal impact of dietary counseling on children's nutrient intake. DESIGN: A prospective, randomized, clinical trial. PARTICIPANTS: Children were recruited to the study between December 1, 1989, and May 30, 1992. At the age of 7 months, children were randomized to the intervention group (n = 540) or the control group (n = 522) and were followed up until the age of 10 years.Intervention Families in the intervention group have, since randomization, received regularly individualized counseling about how to modify the quality and quantity of fat in the child's diet, the goal being an unsaturated-saturated fat ratio of 2:1. MAIN OUTCOME MEASURES: Nutrient intakes between the ages of 4 and 10 years based on annual 4-day food records. RESULTS: The fat intake of the intervention children was constantly around 30% of the calorie (energy) intake, while that of the control children was 2 to 3 calorie percentage units higher (P<.001). The intervention children received 2 to 3 calorie percentage units less saturated fats and 0.5 to 1.0 calorie percentage unit more polyunsaturated fats than the control children (P<.001 for both). However, neither group reached the 2:1 goal set for the unsaturated-saturated fatty acid ratio. The vitamin and mineral intakes of the intervention and control children closely resembled each other despite the marked differences in fat intake. CONCLUSION: Individualized, biannually given, fat intake-focused dietary counseling that began at the child's age of 8 months continued to influence favorably the diet of 4- to 10-year-old intervention children without disadvantageous dietary effects, but the 2:1 goal for unsaturated-saturated fat ratio was not reached.  相似文献
