Teratoma tongue: Case report and review of literature

Teratomas are true neoplasms composed of tissues from all three germinal layers and may exhibit variable levels of maturity. They have an unknown origin and eccentric microscopic appearance. Teratomas arising from the oral cavity are rare in the newborn; only 22 cases have been reported in the literature. We describe a female neonate with an oral teratoma originating from the tongue that was successfully treated with surgery.     

64层螺旋CT诊断先天性冠状动脉起源异常的价值

目的：探讨64层螺旋CT冠状动脉造影诊断冠状动脉起源异常的临床价值。材料和方法：回顾性总结2005年12月至2006年12月间1800例64层螺旋CT冠脉造影的结果，统计冠状动脉起源异常的发生率。结果：1800例检查者中发现冠脉起源异常51例，发病率2．8％。包括右冠状动脉变异11例（21．6％）、左冠状动脉变异8例（15．7％）、左右冠均发生变异1例（2％）、单支冠状动脉1例（2％）、分支变异28例（54．9％）。结论：64层螺旋CT是诊断冠状动脉起源异常的安全有效方法，对临床治疗有重要的意义。     

合并异常冠状动脉法洛四联症和右心室双出口一期根治术

目的 总结合并异常冠状动脉的法洛四联症和右心室双出口一期根治术的经验，探讨有关外科技术的改进。方法1995年6月至2002年6月完成该类一期根治术12例，其中2例采取了肺动脉移位、3例在游离的左前降支下加宽右室流出道、5例改变右室切口并在冠状动脉下缝合、2例经肺动脉和右房疏通流出道。结果无手术死亡。随访3个月～6年，无晚期死亡和并发症发生。结论合并异常冠状动脉的法洛四联症和右心室双出口的一期根治手术是可行的，且效果良好，但必须采用适当的外科技术以保护异常的冠状动脉。     

经导管同期封堵治疗膜周部室间隔缺损合并房间隔缺损

目的　探讨经导管介入同期治疗膜周部室间隔缺损 (VSD)合并房间隔缺损 (ASD)的可行性、方法及疗效。方法　 4例患者 ,年龄为 12～ 2 6岁。术前超声检查提示VSD合并ASD。VSD均为膜周部缺损 ,缺损直径 3～ 6mm ,缺损上缘距主动脉瓣 2～ 6mm。ASD均为继发孔型 ,缺损直径 5～ 8mm。4例患者均于术中先行左心室造影 ,确定VSD适合封堵后 ,先行VSD封堵 ,最后行ASD封堵。结果　 4例患者均经导管一次封堵治疗成功。左心室造影显示VSD呈囊袋型 3例 ,囊袋直径分别为 4、5和 10mm ,封堵器的直径分别为 4、8和 12mm。 1例缺损为管状 ,直径 3.5mm ,用 4mm的封堵器治疗成功。4例患者ASD伸展径为 6～ 10mm ,封堵器直径为 6～ 12mm。所有患者术中及术后无并发症。结论　经导管介入同期封堵治疗膜周部VSD合并ASD具有技术上的可行性、安全性和良好的治疗效果     

Computer tomography in children and adolescents with suspected malformation of the petrous portion of the temporal bone

Purpose: To demonstrate HRCT findings and their therapeutic relevance in suspected congenital hearing disorders. Material and Methods: It was checked in 96 young patients if HRCT findings of the temporal bone could explain functional findings. Furthermore, the therapeutic consequences were noted. Results: Normal CT and normal functional findings were obtained in 49 temporal bones (TB). In conductive hearing loss (41 TB), dysplasias of the conducting apparatus (37 TB) and inflammatory changes (3 TB) were found. Combined hearing loss (18 TB) was clarified completely or partially in half the cases. There were 22 dysplasias of the inner ear, 3 dysplasias of the middle ear, 1 abandoned examination (2 TB), and 55 normal CT findings in senorineural hearing disorders (82 TB). 1 retardate had a malformation of the inner ear and, contralaterally, inflammatory middle ear. In cases of vestibular disorders (24 TB), 14 malformations of the inner ear were detected. An indication for an operation was given in 23 TB. In 22 TB, it was contraindicated. The CT was one preliminary examination to a cochlea implant in 19 patients. The therapy was carried on with hearing devices in the other patients. Conclusion: HRCT is an important method in diagnosis and therapeutic planning of suspected malformations of the temporal bone.      

Left-sided superior vena cava: diagnosis by magnetic resonance imaging

We describe a case of left-sided superior vena cava. The diagnosis was suggested by chest radiograph after central venous catheter placement. This was subsequently confirmed by magnetic resonance imaging. Received: 4 March 1997 Accepted: 21 March 1997     

先天性心脏病与柯萨奇病毒B3,B4感染的关系

采用配对病例对照研究，探讨先心病与柯萨奇病毒B3、B4感染的关系，结果显示：病例组与对照组患儿CVB3、CVB4．IgG抗体阳性率分别为59．3％、54．3％和53．6％、45．7％，差异天显著性（P值均＞0．05）；经单因素和多因素回归分析均未发现CVB3、CVB4感染与先心病有病因学联系（P＞0．05）     

Successful triplet pregnancy in a patient with a unicornuate uterus with a cavitary communicating rudimentary horn

In a patient with primary infertility, ovulation was inducedby monitored stimulation with human menopausal gonadotrophins(HMG) because of polycystic ovarian disease. Infertility work-uphad shown a unicornuate uterus with a cavitary communicatingrudimentary horn. The husband showed a varicocele-related moderateoligoasthenoterato-zoospermia. A triplet pregnancy occurredin a third HMG ovulation induction cycle combined with intra-uterineinsemination of the husband's washed semen. The pregnancy wascarefully monitored, and measures to prevent premature deliverywere taken. Because of the patient's obvious discomfort in thepresence of premature labour, Caesarean section was performedat 33 weeks gestation and three healthy infants were delivered.This is the first report of a successful triplet pregnancy ina women with a unicornuate uterus. The reproductive and obstetricoutcome of this condition in general, and in the case of multiplepregnancy, is discussed.     

Congenital defects of lower limbs and associated malformations: A population based study

As part of a detailed study of limb defects and associated patterns of congenital malformations, cases with lower limb deficiencies were analysed separately. We identified a total of 130 cases with deficiencies of the lower limbs without defects of the upper limbs. This gives an incidence of 1.07/10,000 livebirths, or 1/9,337 for this group of limb defects. Most common were femur deficiencies and deficiencies of the foot. A preponderance of males was found in the group of transverse defects of the leg (fibula/tibia deficiencies) and central axis deficiencies, while females had significantly more often longitudinal tibia defects and preaxial ray defects. © 1993 Wiley-Liss, Inc.
