An account is given of the influence of enibomalum anaesthesia on the condition of infants delivered by Caesarean section. Study groups of 217 acute and 44 non-acute cases are compared with a similar number of controls. The condition of the infants was assessed by estimating the Apgar score 1 minute after birth and by measuring the time taken before normal respiration became established.
It is concluded that a dose of 250 mg or less of enibomalum lowers the infant's Apgar score and delays the onset of normal respiration. It does not influence the mortality during the first week of life. The Apgar score would appear to be a less useful prognostic indicator when enibomalum had been administered to the mother than when it had not been given.

ZUSAMMENFASSUNG


Es wird ein Bericht über den Einfluss der Enibomalanaesthesie auf den Zustand von Säuglingen gegeben, die mittels Kaiserschnitt entbunden wurden. Untersuchungsgruppen von 217 akuten und 44 nicht-akuten Fällen werden mit einer ähnlichen Zahl von Kontrollen verglichen. Die Bewertung des Zustandes der Neugeborenen erfolgte mit Hilfe des Apgar-Schemas eine Minute nach der Geburt und mittels Messung der Zeit bis zum Einsetzen normaler Atmung.
Die Autoren kommen zu dem Schluss, dass eine Dosis von 250 mg oder weniger von Enibomal sowohl die Apgar-Bewertungszahl des Säuglings herabsetzt, als auch das Einsetzen der normalen Atmung verzögert. Die Mortalität während der ersten Lebenswoche bleibt unbeeinflusst. Es scheint, dass das Bewertungsschema nach Apgar bei der Anwendung von Enibomal als prognosticher Hinweis weniger nützlich ist, als wenn die Mutter dieses Anaesthetikum nicht bekommen hat.  相似文献

Testicular germ cell tumors (TGCT) arise by multistep carcinogenesis pathways involving selective losses and gains of chromosome material. To locate cancer genes underlying this selection, we performed a genome-wide study of allelic imbalance (AI) in 32 tumors, using 710 microsatellite markers. The highest prevalence of AI was found at 12p, in line with previous studies finding consistent gain of the region in TGCTs. High frequency of AI was also observed at chromosome arms 4p, 9q, 10p, 11q, 11p, 13q, 16q, 18p, and 22q. Within 39 candidate regions identified by mapping of smallest regions of overlap (SROs), the highest frequency of AI was at 12p11.21 approximately p11.22 (62%), 12p12.1 approximately p13.1 (53%), 12p13.1 approximately p13.2 (53%), 11q14.1 approximately q14.2 (53%), 11p13 approximately p14.3 (47%), 9q21.13 approximately q21.32 (47%), and 4p15.1 approximately p15.2 (44%). Two genes known to be involved in cancer reside in these regions, ETV6 at 12p13.2 (TEL oncogene) and WT1 at 11p13. We also found a significant association (P = 0.02) between AI at 10q21.1 approximately q22.2 and higher clinical stage. This study contributes to the ongoing search for genes involved in transformation of germ cells and provides a useful reference point to previous studies using cytogenetic techniques to map chromosome changes in TGCTs.  相似文献

Measuring serum levels of the prostate-specific antigen (PSA) is the most common screening method for prostate cancer. However, PSA levels are affected by a number of factors apart from neoplasia. Notably, around 40% of the variability of PSA levels in the general population is accounted for by inherited factors, suggesting that it may be possible to improve both sensitivity and specificity by adjusting test results for genetic effects. To search for sequence variants that associate with PSA levels, we performed a genome-wide association study and follow-up analysis using PSA information from 15,757 Icelandic and 454 British men not diagnosed with prostate cancer. Overall, we detected a genome-wide significant association between PSA levels and single-nucleotide polymorphisms (SNPs) at six loci: 5p15.33 (rs2736098), 10q11 (rs10993994), 10q26 (rs10788160), 12q24 (rs11067228), 17q12 (rs4430796), and 19q13.33 [rs17632542 (KLK3: I179T)], each with P(combined) <3 × 10(-10). Among 3834 men who underwent a biopsy of the prostate, the 10q26, 12q24, and 19q13.33 alleles that associate with high PSA levels are associated with higher probability of a negative biopsy (odds ratio between 1.15 and 1.27). Assessment of association between the six loci and prostate cancer risk in 5325 cases and 41,417 controls from Iceland, the Netherlands, Spain, Romania, and the United States showed that the SNPs at 10q26 and 12q24 were exclusively associated with PSA levels, whereas the other four loci also were associated with prostate cancer risk. We propose that a personalized PSA cutoff value, based on genotype, should be used when deciding to perform a prostate biopsy.  相似文献

Introduction:

A significant proportion of high-risk breast cancer families are not explained by mutations in known genes. Recent genome-wide searches (GWS) have not revealed any single major locus reminiscent of BRCA1 and BRCA2, indicating that still unidentified genes may explain relatively few families each or interact in a way obscure to linkage analyses. This has drawn attention to possible benefits of studying populations where genetic heterogeneity might be reduced. We thus performed a GWS for linkage on nine Icelandic multiple-case non-BRCA1/2 families of desirable size for mapping highly penetrant loci. To follow up suggestive loci, an additional 13 families from other Nordic countries were genotyped for selected markers.

Methods:

GWS was performed using 811 microsatellite markers providing about five centiMorgan (cM) resolution. Multipoint logarithm of odds (LOD) scores were calculated using parametric and nonparametric methods. For selected markers and cases, tumour tissue was compared to normal tissue to look for allelic loss indicative of a tumour suppressor gene.

Results:

The three highest signals were located at chromosomes 6q, 2p and 14q. One family contributed suggestive LOD scores (LOD 2.63 to 3.03, dominant model) at all these regions, without consistent evidence of a tumour suppressor gene. Haplotypes in nine affected family members mapped the loci to 2p23.2 to p21, 6q14.2 to q23.2 and 14q21.3 to q24.3. No evidence of a highly penetrant locus was found among the remaining families. The heterogeneity LOD (HLOD) at the 6q, 2p and 14q loci in all families was 3.27, 1.66 and 1.24, respectively. The subset of 13 Nordic families showed supportive HLODs at chromosome 6q (ranging from 0.34 to 1.37 by country subset). The 2p and 14q loci overlap with regions indicated by large families in previous GWS studies of breast cancer.

Conclusions:

Chromosomes 2p, 6q and 14q are candidate sites for genes contributing together to high breast cancer risk. A polygenic model is supported, suggesting the joint effect of genes in contributing to breast cancer risk to be rather common in non-BRCA1/2 families. For genetic counselling it would seem important to resolve the mode of genetic interaction.  相似文献

Purpose: To determine the incidence rate as well as causative diagnoses and surgical indications of enucleation in Iceland during the years 1992–2004. Methods: A retrospective population‐based incidence study involving the entire population of Iceland. Medical records of all patients who underwent enucleation in Iceland from January 1992 through December 2004 were reviewed. The annually updated Icelandic census was used as a denominator data. Results: Fifty‐six eyes were enucleated during 1992–2004. No eviscerations were done, and the three exenterations performed were not included in the study. The mean annual age‐adjusted incidence rate of enucleation in Iceland was 1.48 enucleations per 100 000 population in comparison with 2.66 enucleations per 100 000 for the time period 1964–1991. With advancing age, a significant increasing linear trend existed (p < 0.001). The median age at enucleation was 51 years (SD 22; mean 55 years; 16–91 years). The three most common surgical indications for enucleation were blind painful eye, suspected ocular malignancy and acute trauma. The most common causative diagnosis for enucleation was traumatic lesion (39%). The annual incidence was 2.00 enucleations per 100 000 for men and 0.95 for women. There were significantly more men in the traumatic lesion group (p < 0.001), but no gender predominance was found in the other groups of causative diagnoses (p = 0.8). Conclusion: The overall mean annual incidence of enucleation in Iceland is continually decreasing, although the incidence of severe ocular trauma and ocular malignancy is fairly stable.  相似文献

Objective: To compare the effects of an experimental mouth rinse containing 0.07% cetylpyridinium chloride (CPC) (Crest Pro‐Health®) with those provided by a commercially available mouth rinse containing essential oils (EOs) (Listerine®) on dental plaque accumulation and prevention of gingivitis in an unsupervised 6‐month randomized clinical trial. Material and Methods: This double‐blind, 6‐month, parallel group, positively controlled study involved 151 subjects balanced and randomly assigned to either positive control (EO) or experimental (CPC) mouth rinse treatment groups. At baseline, subjects received a dental prophylaxis procedure and began unsupervised rinsing twice a day with 20 ml of their assigned mouthwash for 30 s after brushing their teeth for 1 min. Subjects were assessed for gingivitis and gingival bleeding by the Gingival index (GI) of Löe & Silness (1963) and plaque by the Silness & Löe (1964) Plaque index at baseline and after 3 and 6 months of rinsing. At 3 and 6 months, oral soft tissue health was assessed. Microbiological samples were also taken for community profiling by the DNA checkerboard method. Results: Results show that after 3 and 6 months of rinsing, there were no significant differences (p=0.05) between the experimental (CPC) and the positive control mouth rinse treatment groups for overall gingivitis status, gingival bleeding, and plaque accumulation. At 6 months, the covariant (baseline) adjusted mean GI and bleeding sites percentages for the CPC and the EO rinses were 0.52 and 0.53 and 8.7 and 9.3, respectively. Both mouth rinses were well tolerated by the subjects. Microbiological community profiles were similar for the two treatment groups. Statistically, a significant greater reduction in bleeding sites was observed for the CPC rinse versus the EO rinse. Conclusion: The essential findings of this study indicated that there was no statistically significant difference in the anti‐plaque and anti‐gingivitis benefits between the experimental CPC mouth rinse and the positive control EO mouth rinse over a 6‐month period.  相似文献

BACKGROUND & AIMS: It has been suggested that subclinical intestinal inflammation plays a pathogenic role in the spondylarthropathy of ankylosing spondylitis (AS). We assessed the possible presence and inheritance pattern of subclinical intestinal inflammation in first-degree relatives of patients with AS. The relationship between this inflammation and the subjects' HLA-B27 genotype as well as computerized tomographic sacroiliac abnormalities was also assessed. METHODS: A total of 124 of 213 (58%) available first-degree relatives of 47 patients with AS in Iceland underwent investigation for intestinal inflammation (fecal calprotectin concentration), HLA-B27 genotyping, and computerized tomography of the sacroiliac joints. RESULTS: A total of 41% of the first-degree relatives had subclinical intestinal inflammation, whereas 15 of 17 spouses were normal. Variance components analyses suggest that the inheritance pattern of this inflammation is affected by a major additive gene. Some sacroiliac changes, suggestive of early AS, differed significantly between subjects with and without subclinical intestinal inflammation (mean diameter of subchondral cysts [2.9 vs. 1.2 mm; P = 0.026] and blurring of joint margins [9 of 44 (20%) vs. 1 of 41 (2%); P = 0.02]). Intestinal inflammation and sacroiliac changes did not relate to the subjects' HLA-B27 status. CONCLUSIONS: Many first-degree relatives of patients with AS appear to have an inherited abnormality that leads to subclinical intestinal inflammation. The association between the presence of this inflammation and the sacroiliac changes suggests that it may play a pathogenic role in the spondylarthropathy of AS.  相似文献

Statement of problem

Gingival recession after soft tissue displacement for impression making in fixed prosthodontics may pose a problem for treatment success in the esthetic areas of the mouth. Knowledge about the soft tissue reaction of common gingival displacement methods is limited.

Purpose

The purpose of this clinical randomized controlled trial (RCT) was to evaluate changes in the marginal soft tissue height with 3 different gingival tissue displacement techniques for definitive impression making of natural teeth.

Material and methods

A total of 67 individuals were randomized to 3 groups. In test group 1 (P; n=22), only aluminum chloride paste was used to displace the gingiva. In test group 2 (CP; n=23), a cord was inserted, and aluminum chloride paste was also used. In the control group (C; n=22), 2 cords were used to displace the gingiva (double-cord technique). Clinical measurements of the gingival position were made before treatment began and at 30 ±10 days after prosthesis delivery. Study casts were fabricated at different stages of the treatment, standardized photographs were made, and changes in the buccal gingival position were measured using graphics editing software. In addition, the participants’ perception of the clinical procedure and the technicians’ evaluation of the die preparation were recorded. One-way ANOVA models were applied to compare the response variables among the groups: (a) the position of the gingival margin (millimeters), (b) mean probing pocket depth (millimeters), (c) gingival thickness (millimeters), (d) amount of keratinized tissue (millimeters), and (e) mean changes in gingival margin height (millimeters). Unpaired t tests were also used to compare the mean values between groups. For comparisons between different categories, chi-square tests were performed (α=.05 for all tests).

Results

In the period between impression and delivery, a minor gain in gingival height of 0.058 mm (±0.13 SD) for P and 0.013 mm (±1.19 SD) for CP. However, a minor gingival recession of 0.049 mm (±0.13 SD) was reported for group C. The results for all groups showed that 21% of abutment teeth gained >0.1 mm in gingival height, 58% had stable gingival height (0 ±0.10 mm), 21% showed minor gingival recession (0.1 to 0.5 mm), and no abutment teeth showed moderate or severe gingival recession (>0.5 mm). The incidence of minor gingival recession was 8% in group P, 23% in group CP, and 32% in group C (P=.015). Fifteen participants (24%) experienced some discomfort after the procedure. The differences between the groups were not significant (P>.05). The laboratory technicians found the definitive die preparation significantly more challenging for group P (visual analog scale [VAS], 79) and CP (VAS, 82) than group C (mean VAS, 93; P=.003).

Conclusions

Minor or moderate gingival recession (<1 mm) is more likely to occur when conventional cords are used during impression making. However, the laboratory technicians found the die preparation significantly less challenging when the double-cord technique was used than when impressions were made using the paste displacement technique.  相似文献

Adhesive cementation is a useful procedure not only for cementing restorations onto teeth but also for attaching new ceramic restorations to existing restorations to improve their esthetics and/or function. This clinical report presents a technique for modifying an existing nonsatisfactory implant-supported fixed dental prosthesis by means of adhesively cemented veneers and onlays bonded to the pre-existing metal-ceramic surface with resin cement. This modification may avoid the replacement of the fixed dental prosthesis, reducing both treatment costs and time while fulfilling the patient’s demands.  相似文献

Mesenteric panniculitis presenting with autoimmune haemolytic anaemia   总被引:1,自引:0,他引:1  
Mesenteric panniculitis is a rare idiopathic inflammatory disorder that can lead to sclerosis. We describe a patient with mesenteric panniculitis presenting with abdominal symptoms and autoimmune haemolytic anaemia. The symptoms remitted after splenectomy and gradual steroid taper. This may suggest an autoimmune component in the aetiology of mesenteric panniculitis.  相似文献
