Otorhinolaryngology

Otorhinolaryngology, a product of the early 20th century, developed from the joining together of the separate departments of otology, whose practitioners were surgeons, and laryngology which was managed by physicians who also treated diseases of the nose and chest. The 20th century opened with brave attempts to perform skilful surgery under conditions of primitive anaesthesia and no antibiotics. The stimulus of two world wars led to significant advances in technology and greater opportunities to explore new and resurrect old surgical procedures. The discovery of antibiotics saw an end to acute mastoiditis and the complications of otitis media and sinusitis, as well as a decline in the number of tonsillectomy and adenoidectomy operations. Over the last 30 years the specialty has undergone dramatic development and has taken advantage of new advances in endoscopy, microsurgery, the use of lasers, cytotoxic drugs, flap reconstruction and microchip technology. During the same period, although still calling themselves otorinolaryngologists, individual surgeons have subspecialised in otology, otoneurosurgery and skull-base surgery, head and neck surgery, phonosurgery, rhinology and facioplastic surgery, and paediatric otothinolaryngology. Each of these subspecialties has its own societies and specialist journals.

绞股蓝总甙复合国产1号避孕片对健康妇女脂类代谢及血压的影响

本研究将180名已婚、一孩、年龄33±5岁,需要使用避孕措施的健康妇女随机分成6组,即IUD组、绞股蓝总甙加IUD组、1号OC片组、40mg、60mg、80mg绞股蓝总甙分别与1号OC片复合的3个试验组.用双盲法给药,连续服用6个月观察脂类代谢和血压的变化.结果显示:以IUD组和1号OC片组的数据为参比值.服用不同剂量绞股蓝总甙复合口服避孕药后无升高TG和TC的趋势,有显著升高HDL-C作用和使APOA_1水平上升的趋势;亦存在降低收缩压的趋势,对舒张压无明显影响,但在服药后3个月时HDL-C水平曾发生暂时性下降.     

Diagnosis: toxic!--trying to apply approaches of clinical diagnostics and prevalence in toxicology considerations.

The assessment of relevance of toxicological testing was compared with approaches of diagnostic medicine, a discipline that faces a comparable situation. Considering the work of a toxicologist as setting a diagnosis for compounds, assessment tools for diagnostic tests were transferred to toxicological tests. In clinical diagnostics, test uncertainty is well accepted and incorporated in this assessment. Furthermore, prevalence information is considered to evaluate the gain in information resulting from the application of a test. Several common toxicological scenarios, in which test uncertainty and prevalence are combined, are discussed including the interdependence of test accuracy, prevalence and predictive values or the sequential application of a screening and a confirmatory test. In addition, real prevalences derived from prevalences determined by an imperfect test are presented. We conclude that information on prevalences of toxic health effects is required to allow a complete assessment of the relevance of toxicological test. In this process, lessons can be learned from evidence-based approaches in clinical diagnostics.

Future anesthesiologists will be as much outside as inside operating theaters

During the first decade of the new millennium the intense reorganization of hospitals and of medical care will be replaced by stability and long-term goals. An anesthesiologist is now as active outside as within the operating theater, being a predominant resource in intensive care, pain management, emergency and prehospital care. The anesthesiologist will also have a key part to play in risk analysis of patients scheduled for various kinds of advanced treatment. Anesthesiologists are now also more involved in primary home care where, together with other physicians and categories of health care providers, they offer qualified treatment of various diseases at home – the environment preferred by the patient.     

No genotoxic effect of propofol in chinese hamster ovary cells: analysis by sister chromatid exchanges

BACKGROUND: In spite of its high placental transfer, propofol is frequently used in general anesthesia and sedation during obstetric and gynecological surgery such as in vitro fertilization. This study investigated whether or not propofol has a genotoxic potential by the sister chromatid exchange assay in vitro. METHODS: Sister chromatid exchanges induced after exposure to propofol were measured in Chinese hamster ovary cells with and without metabolic activation. After propofol (0.2-20 microg ml(-1)) diluted dimethyl sulfoxide was applied for 2 h with or without S9 mix, the cells having been incubated for two metaphases (34 h) in the presence of 5'-bromo-2-deoxyuridine. N-nitrosodimethylamine and mitomycin C were used as positive controls with and without metabolic activation. The chromosomes were stained with the fluorescence plus Giemsa method, and then sister chromatid exchanges in 50 cells were counted for each concentration. RESULTS: Although increasing concentrations of propofol inhibited cell proliferation, no concentrations of propofol used in this study increased the sister chromatid exchange values, with and without metabolic activation. CONCLUSION: It was concluded that there was no indication, from the sister chromatid exchange assay in mammalian cells, of a genotoxic effect of propofol and its metabolites.
