Onychopathy in a Patient with Fetal Hydantoin Syndrome

Abstract: Hydantoin is an anticonvulsant drug with several side effects. A teralogenic potential has been suggested. The fetal hydantoin syndrome is an entity that consists of a broad range of morphologic and developmental disorders in children born of epileptic mothers exposed to hydantoin during pregnancy. We treated a girl in whom onychopathy was a monosymptomatic or mild form of this syndrome.     

Perioperative effects of oral ketorolac and acetaminophen in children undergoing bilateral myringotomy

Prophylactic administration of analgesics before surgery can decrease the intraoperative anaesthetic requirement and decrease pain during the early postoperative period. In a double-blind, placebo-controlled study involving 90 healthy ASA physical status I or II children undergoing bilateral myringotomy, we compared the postoperative analgesic effects of oral acetaminophen and ketorolac, when administered 30 min before induction of anaesthesia. Patients were randomized to receive saline (0.1 ml.kg-1), acetaminophen (10 mg.kg-1) or ketorolac (1 mg.kg-1) diluted in cherry syrup to a total volume of 5 ml. Anaesthesia was induced and maintained with halothane and nitrous oxide via a face mask. Postoperative pain was assessed by a blinded observer using an objective pain scale. The three study groups were similar with respect to demographic data, duration of anaesthesia and surgery, induction behaviour, oxygen saturation, incidence of postoperative emesis and, recovery times. The ketorolac group had lower postoperative pain scores and required less frequent analgesic therapy in the early postoperative period compared with the acetaminophen and placebo groups. In contrast, there were no differences in pain scores or analgesic requirements between the acetaminophen and the placebo groups. We conclude that the preoperative administration of oral ketorolac, but not acetaminophen, provided better postoperative pain control than placebo in children undergoing bilateral myringotomy.     

护生自身练习护理操作的伦理问题及对策

自身练习护理操作就是以护生作为练习对象,相互间在各自身上完成注射、输液等操作练习项目,以达到教学要求[1]。在基础护理的教学中,自身练习对于调动护生的参与感,增加真实感,满足成就感方面起着十分重要的作用。但是,也必须看到在积极效果背后的种种矛盾以及由这些矛盾可能导     

Preparation and identification of monoclonal antibodies against Penicillium marneffei]

OBJECTIVE: To prepare and identify monoclonal antibodies (mAbs) against Penicillium marneffei. METHODS: Recombinant mannoprotein1 (MP1) of Penicillium marneffei was used to immunize BALB/c mice, and anti-MP1 mAbs were obtained by means of hybridoma. Screening and identification of the mAbs were subsequently performed with indirect enzyme-linked immunosorbent assay and Western blotting, respectively. RESULTS: Four hybridomas producing antibodies against Penicillium marneffei were obtained, and the IgG isotypes of the 4 mAbs were identified as IgG1 with affinity constants (K) of 8.2x10(-9), 4.7x10(-9), 6.5x10(-9) and 2.7x10(-9), respectively. Western blotting demonstrated specific recognition of Aspergillus fumigatus MP1 by the obtained mAbs. CONCLUSION: The 4 hybridomas producing anti-MP1 mAbs with high specificity and affinity can be of significant value in the diagnosis of Penicilliosis marneffei infections.

MR扩散加权成像鉴别脑结核瘤及高级星形细胞瘤和脑转移瘤的价值

目的探讨MR扩散加权成像（DWI）在脑结核瘤、高级星形细胞瘤和脑转移瘤鉴别诊断中的价值。方法14例脑结核瘤、15例脑高级星形细胞瘤和21例脑转移瘤患者，在术前或接受治疗前行常规MRI和DWI。测量并计算3种疾病瘤体、瘤周围水肿带的平均表观扩散系数（ADC）值和病灶与对侧相应部位正常脑白质区ADC值的比值（rADC值）。结果脑结核瘤瘤体平均ADC值和rADC值分别为（1．2±0．2）×10^-3mm^2·s^-1和1．6±0．3，高级星形细胞瘤瘤体平均ADC值和rADC值分别为（0．8±0．1）×10^-3mm^2·s^-1和1．1±0．1，转移瘤瘤体平均ADC值和rADC值分别为（0．8±0．1）×10^-3mm^2·s^-1和1．0±0．2。3种疾病瘤体平均ADC值（F=33．57，P〈0．01）之间和rADC值（F=33．27，P〈0．01）之间差异均有统计学意义。脑结核瘤瘤周水肿带平均ADC值和rADC值分别为（1．8±0．1）×10^-3mm^2·s^-1和2．5±0．2，脑高级星形细胞瘤瘤周水肿带平均ADC值和rADC值分别为（1．4±0．2）×10^-3mm^2·s^-1和1．8±0．3，脑转移瘤瘤周水肿带平均ADC值和rADC值分别为（1．9±0．2）×10^-3mm^2·s^-1和2．3±0．5。3种疾病瘤周围水肿带平均ADC值（F=23．17，P〈0．01）之间和rADC值（F=5．94，P〈0．01）之间差异均有统计学意义。结论结合MRI、DWI检测方法，根据病灶瘤体和瘤周水肿带的ADC和rADC值可帮助鉴别脑结核瘤、脑高级星形细胞瘤和脑转移瘤。
