Craniofacial clefts are rare among facial anomalies with an incidence of 1.5 to 5 per 100,000 births, and 1 per 100 cases of cleft lip and palate. The Tessier No. 7 clefts are unusual lesions that result from failure of the embryonic mandibular and maxillary processes to properly fuse and form the corners of the mouth. We experienced a case of Tessier No. 7 craniofacial cleft in a 1 day-old female patient who presented with a macrostomia and auricular malformation. The diagnosis was established by clinical and radiographic findings. A brief review of literature was made.

BACKGROUND: We designed this study to determine whether trauma history and initial assessment anticipate the injury severity of the free-fall patient. METHODS: Two hundred patients who admitted emergency department of Severance hospital because of the fall from a height were enrolled in this study. The height of fall, the body orientation, and the characteristics of impacted material, and the Injury Severity Score(ISS) were evaluated by retrospective chart reviews. And regression equations were determined for predicting ISS on the basis of clinical parameters using multiple regression analysis. RESULTS: According to the characteristics of impacted material, the ISS was higher in the hard surface(13.7+/-9.5) than the sort surface(10.5+/-8.8)(p<0.05). There were correlations between height of fall and ISS(p<0.01, r=0.5). To the body orientation, the ISS was higher in the head-to-feet orientation(18.211.7) than the feet-to-head(10.9+/- 7.0) or other position(8.5+/-5.8)(p<0.01). The regression equations were as follows, ISS=2 +0.082xage(year)-1.54x(Glasgow Coma Scale)-3x(feet-to-head orientation)+0.65x height of fall(m)+2.7 x (hand surface)(p<0.01, R2=0.53). CONCLUSION: This study suggest that the injury severity of patient with free fall are significancy related to the height of fall, the characteristics of impacted material and the body orientation.

In evaluating the early state of shock patients and their response to treatment, generally vital signs or additional hemodynamic values were used. Vital signs are easily obtained and repetitious values or continous monitoring is possible, whereas it cannot evaluate the patient's status properly nor is it a good prognostic factor. Meanwhile, additional hemodynamic values are obtained from pulmonary artery catheterization. But this procedure is difficult to proceed in the emergency room. Since central venous oxygen saturation has the advantage of being easily obtained and acts as a good prognostic factor for shock patients, we intended to prove its efficacy. From 1997 May to October, 50 patients admitted to Yonsei University Young Dong Severance Hospital in shock state, with systolic blood pressure below 90mmHg, were evaluated. Central venous catheter was inserted to obtain central venous oxygen saturation, serum lactate, base excess value, and its' initial value compared with the prognosis. The central venous oxygen saturation and base excess were low, while serum lactate value was high in the nonsurvival group. And in ROC(relative operating characteristic) curve, the AUC(area under curve) of central venous oxygen saturation was larger than the others. In comparing the MOF(multi-organ failure) group with the non-MOF group, the MOF group had a lower central venous oxygen saturation and base excess, and a higher serum lactate level, whereas in ROC curve, the AUC of base excess was larger than the others. Therefore, in estimating the prognosis of shock patients, the early central venous oxygen saturation proved to be a good prognostic factor.

BACKGROUND: Ischemic preconditioning(a prior short period of coronary artery occlusion) has been known to have protective effects on ischemia-induced myocardial injury. The purpose of this study was to investigate the effects of hypoxic preconditioning or ischemic preconditioning on the

Nitric oxide (NO) has been emerged as an important intracellular and intercellular regulatory molecule having functions as diverse vasodilatation, neural communication, and host defense. In the immune system, NO produced by activated macrophage or neutrophil is known to kill tumor cells as a defense molecule. In addition, recent reports demonstrated that NO could interact with superoxide to generate peroxynitrite (ONOO-), an anion and a potent oxidant, in macrophages or other cellular systems. The production of peroxynitrite has been recognized to be associated with the activation and expression of inducible NO synthase (iNOS). In this study, to evaluate the role of NO and peroxynitrite in murine bladder tumor cells, the author investigate the effect of NO and peroxynitrite on the viability, cytotoxicity, and DNA fragmentation of MBT-2 cells. The results are as followings: 1. Activated macrophages treated with INF-r, LPS, or INF-r+ LPS showed increment of nitrite (NO2) production and cytotoxicity against MBT-2 cells in a dose dependent manner. However, treatment with NGMMA, a NOS inhibitor, decreased NO2- production and cytotoxicity. 2. Treatment with SNP, a nitric oxide donor, increased NO2 production and DNA fragmentation (%), but decreased viability (%) of MBT-2 cells in a concentration dependent manner. 3. Treatment with peroxynitrite increased cytotoxicity and DNA fragmentation, but decreased viability of MBT-2 cells in a concentration dependent manner. 4. NO- and peroxynitrite-mediated increment of cytotoxicity in MBT-2 cells was corresponded to the programmed cell death, apoptosis. Taken together, these data indicate that NO and peroxynitrite elaborated from macrophages or other cellular systems may increase the cytotoxicity of MBT-2 cells via the mechanism of apoptosis.
