应重视口腔颌面部恶性肿瘤的综合序列治疗

口腔颌面部恶性肿瘤约占全身恶性肿瘤的3％，虽然所占比例不高，但l大l其解剖部位特殊．涉及美观和重要的生理功能，冈此对患者机体和心理的影响不容忽视。早期（Ⅰ、Ⅱ期）口腔颌面部恶性肿瘤无论采用手术和（或）放射治疗，均能取得良好效果。但遗憾的是，大多数患者就诊时，已属局部一区域晚期（Ⅲ、Ⅳ期）。由于受到局部解剖和维持功能的限制，单纯通过扩大手术切除范围和改进现有手术技术，除能改善患者生存质量外，已无法提高此类患者的生存率，延长其生存时间。     

异位妊娠259例临床总结分析

目的探讨异位妊娠的发病相关因素,提出防治措施。方法对我院10年间收治的259例异位妊娠病例的发病趋势,既往病史及节育状况、误诊情况作一回顾分析。结果近10年异位妊娠发生率为2.19%并呈上升趋势。人工流产、节育手术、下腹部手术等与异位妊娠的发生关系密切。结论降低人工流产率,减少性病传播是预防异位妊娠发生的重要手段,随着高科技手段的应用使异位妊娠早期准确的诊断成为可能,为保守治疗赢得机会。     

调脂宜从肝脾入手

中医学认为血脂异常在病机方面属“痰浊”、“血瘀”范畴，生理上与中医之膏脂相类似，属津液之范畴，肝脾功能的正常是血脂正常代谢的重要条件，脾“化”的相对不足是血脂代谢异常的根本原因；肝失疏泄是血脂代谢失常的重要因素，治疗的根本在于截断血脂失调的源头，或者扭转已有的病理趋势，使其不再发生代谢紊乱。     

Serum IgA and IgG functional antibodies and their subclasses to Streptococcus pneumoniae capsular antigen found in two aged‐matched cohorts of children with and without otitis media with effusion

Serum IgA and IgG functional antibodies and their subclasses to Streptococcus pneumoniae capsular antigen found in two aged‐matched cohorts of children with and without otitis media with effusion The relationship between acute otitis media and otitis media with effusion (OME) is uncertain and the aetiology of OME is multifactorial. Otitis media with effusion may be an inflammatory condition; both bacteria and viral infections could play a part in this inflammation. The four bacteria Streptococcus pneumoniae, Haemophilus influenza, Staphylococcus aureus and Branhamella catarrhalis cause 60% of the infections whereas S. pneumoniae accounts for up to 35%. IgA provides the dominant surface response to polysaccharide and lipopolysaccharide antigens, of which IgA₂ is the main subclass. Once the mucosa has been breached, most protection is provided by IgG. IgG₂ acts mainly against bacterial capsular antigens. This study looked at two groups of 50 children with and without OME who were aged between 3 and 10 years. The aims were to determine if, firstly, the levels of the serum immunoglobulins were different in the two groups, secondly whether these children made the appropriate antibody response to the capsular antigen to S. pneumoniae (PCP), and finally if there was a delay in the maturity of the IgA response. The total IgG, IgA and all subclass levels were measured using radial immunodiffusion. Levels of functional IgA and IgG were measured using ELISAs (25 patients in each group). The results were analysed with non‐parametric tests. The immunoglobulin levels were within the normal levels for both groups. There were very good correlations between the IgG total anti‐PCP and the IgG₂ anti‐PCP (R > 0.9, p = 0.001). There was a good correlation between the levels of both IgG total and IgG₂ anti‐PCP against IgA total anti‐PCP in both groups (R > 0.85, p > 0.01). This confirms a normal antibody response between both groups of patients. The ages of the controls and patients (50 samples) were correlated with increasing titres of circulating functional antibodies (P = 0.001). This is highly suggestive of a normal age‐related response. In conclusion, the findings were contradictory to our original hypothesis that there is a subtle difference in surface protection between children with and without OME. We believe that a previous history of recurrent acute otitis media is unrelated to the development of OME after 3 years of age.     

Impact of cosmetic care on quality of life in breast cancer patients during chemotherapy and radiotherapy: an initial randomized controlled study

BACKGROUND: Breast cancer is the most common cancer in women and therefore represents a major problem in public health. Data from patients' self-report questionnaires provide valuable information about the side-effects that patients may view as having a significantly detrimental impact on their quality of life (QOL) and yet are not always recognized as important by healthcare professionals. Cosmetology is a specific care for patients and there is actually no scientific evidence regarding effects on QOL for women with breast cancer. OBJECTIVE: The purpose of this study is to assess the impact of cosmetic care on QOL in breast cancer patients during chemotherapy and radiotherapy. METHODS: We developed a prospective, multicentre, randomized, controlled study including 27 patients. All the patients had to fill in a French-validated dermatologic specific quality-of-life questionnaire to compare the QOL of the two groups, the cosmetic group and the control group, at three different times of the adjuvant treatment. RESULTS: The results show a statistically significant difference between the cosmetic group and the control group in two areas of QOL: mood state and self-perception of the disease. CONCLUSION: This study emphasizes the interest of cosmetic care in breast cancer patients. However, further larger trials are needed to confirm this study.     

腹腔镜辅助下大隐静脉隔绝术治疗大隐静脉曲张60例

唇腭裂患者上颌骨牵引成骨术后发音方式的变化

目的:通过对行颅外支架式上颌骨牵引成骨术(rigidexternaldistraction,RED)唇腭裂患者治疗前后的错误发音数量变化、不同发音部位、不同发音方法以及不同类型错误发音发生特点及其变化评价,分析上颌骨RED对患者发音方式的影响。方法:1999年至2001年行上颌骨RED的唇腭裂术后上颌发育不足患者21例,其中男性13例,女性8例,平均年龄15.05岁。所有患者RED前后进行语音测听并分类。治疗前后错误发音的差异性用非参数检验。结果:RED术后42.9%患者错误发音数较RED前增加,19.0%减少,38.1%无变化。从发音部位,舌尖前音错误发音发生率最高,其次为舌面音。从发音方法,错误发音多发于塞擦音。错误发音类型以咽喉摩擦/爆破音为主,其次为腭化构音和声门爆破音。上颌骨RED后腭化构音累及音节数减少,但咽喉摩擦/爆破音和声门爆破音反而增加,尤其是咽喉摩擦/爆破音。结论:唇腭裂患者经RED前移上颌骨后,会对患者发音方式产生影响,在行语音治疗前需考虑全面。
