Craniofacial clefts are rare, mysterious and variable congenital anomalies. The incidence of craniofacial clefts is at least 1 per 100,000 live births. The cause of craniofacial clefts remains obscure, and attempts to classip craniofacial clefts are replete with problems. Tessier presented his classification in 1973 and used the orbit to distinguish the facial clefts from the cranial clefts. He noted that those lesions that involve both the face and cranium tend to do so in a consistent, predictable fashion. The clefts are numbered from 0 to 14 and are oriented around the orbit like spokes of a wheel. Van der Meulen proposed a classification in 1983 on an embryologic basis. The term dysplasia was used instead of cleft, since some of the malformations do not represent true clefts. Between 1997 to 1998, authors experienced 3 cases of median and paramedian facial cleft. One was No.2 facial cleft and the others were No.0-14 facial cleft with orbital hypertelorism. Their ages ranged from 1 to 5 years.

Vascular leak syndrome(VLS) is characterized by endothelial damage, which causes extravasation of plasma proteins and fluid from capillaries into the extravascular space. It has been suggested that the increased vascular permeability is the result of an IL-2-induced suppression of endothelin-1 secretion by endothelial cells, an IL-2-induced activation of the complement cascade or TNF-alpha release from IL-2-activated T-cells. A 13-year-old male patient visited our hospital with abdominal pain. He was diagnosed with acute lymphoblastic leukemia(T cell type) by bone marrow study on his 2 nd day in hospital. On the 3 rd day of induction chemotherapy(prednisone, L-asparaginase, vincristine, intrathecal methotrexate), pulmonary edema and pleural effusion, ascites and generalized edema developed and lasted for 53 days without responding to supportive care. The laboratoy finding was that TNF-alpha was increased without evidence of infection and hypoalbuminemia was noted. It was suggested that the patient's clinical feature was induced by VLS.

Eosinophilia is a common finding in premature babies during the neonatal period. Serial eosinophil counts were determined in 94 hospitalized, appropriately grown premature in fants whose gestational ages ranged form 28 to 36 weeks. The incidence, severity and etiologic factors of eosinophilia were retrospectively studied in premature infants, who were divided into three groups according to their gestational age. The results were as follows: 1) Absolute eosinophilia (>700/mm3)was documented in 46.8%(44/94). 2) The duration of TRN and antibiotics was cignificantly higher in infants with eosinophilia than withour eosinophilia (p<0.05). The gestational age of the infants with eosinophilia was significantly shorter than that of the infants without eosinophilia (p<0.05). The infants with eosinophilia started with bottle feeding significantly earlier than the infants without eosinophilia (p<0.05). 3) The infants younger than 30 weeks of gestational age have greater incidence of eosinophilia (75%) than the infant with the gestational age between 34 and 36 weeks (34.3%)(p<0.05). 4) The incidence of mild eosinophilia was higher in the group with gewtational age 30 weeks or below(37.5%)than in the group with gestational age between 34 and 36 weeks(17.1%)(p<0.05).Also, the incidence of severe eosinophilia was significantly higher in the group with gestational age 30 weeks or below(37.5%)than in the group with gestational age between 34 and 36 weeks(17.1%)(p<0.05). 5) Eosinophilia was more prevalent in the infants who received parenteral nutrition composed of glucose, amino acid and lipid(77.8%) than the infants who received only glucose(34.1%)(p<0.05). 6) Gestational age and birth weight were significantly lower in infants with severe eosinopilia than those of mild or moderate eosinophilia. The duration of TRN and antibiotics were significantly longer in infants with severe eosinophilia than those of mild or moderate eosinophilia (p<0.05). 7) The peak eosinophil count was observed significantly later in severe eosinophilic group (26.5 13.1 days)than in non-eosinophilic group(14.4 9.0 days)(p<0.05). The above results suggest that eosinophilia in premature infants may be the effecto of immature immunologic responses to the intravenous administration of extemal antigens like amino acid, lipid and antibiotics.

Craniofacial cleft is a rare disease, and has multiple variations with a wide spectrum of severity. Among several classification systems of craniofacial clefts, the Tessier classification is the most widely used because of its simplicity and treatment-oriented approach. We report the case of a Tessier number 3 cleft with wide soft tissue and skeletal defect that resulted in direct communication among the orbital, maxillary sinus, nasal, and oral cavities. We performed soft tissue reconstruction using the straight-line advanced release technique that was devised for unilateral cleft lip repair. The extension of the lateral mucosal and medial mucosal flaps, the turn over flap from the outward turning lower eyelid, and wide dissection around the orbicularis oris muscle enabled successful soft tissue reconstruction without complications. Through this case, we have proved that the straight-line advanced release technique can be applied to severe craniofacial cleft repair as well as unilateral cleft lip repair.

A case of subgaleal hematoma accompanying ipsilateral exophthalmos is reported. The exophthalmos is due to orbital extension of subgaleal hematoma through potential gap between orbital septum and the lateral horn of the levator palpebral aponeurosis. We must remember that exophthalmos is able to occur after subgaleal hematoma.

BACKGROUND: Oncogenes and EGF-Receptor(EGFR) may be involved n different stages of the multistep carcinogenesis process. A specific pattern of karyotypic abnormalities in solid tumors can be detected by cytogenetic methods. OBJECTIVE: This study is intnded to observe the cytomolecular kiologic chracterization of c-myc, erb B and EGFR genes in squasnous cell carcinoma(SCC) of the skin and cervix. METHODS: We have eytogenet,ically examined the short-term culturs from SCC. The rearrangement, amplification or expressi.on of erb B, c-myc, and EGFR genes were studied by Southern blot, analysis of genomic DNA and by slot blot analysis of tota! RNA extracted from biopsies of normal skin and SCC tissues. EGFR expression was examined immunohistochemially using monoclonal antibodies and the localizat,ion of the c-myc oncogene mRNA by in situ hybridization. RESULTS: A remarkably structural aberration was del 6(q21-qter) counted 20 metaphases among 28 metaphases ana1yzed. In nunierical aberration, all chromosomes were lost or gained randomly. Amenploid including triploid and tetraploid were observed in 8 metaphases, 6 tumor cells contained marker chromosome. In Southern blot analysis, rearrangement and amglificaton of EGFR in primary squamous cell carcinoma of cervix uteri and skin respectively. In slot blot analysis, the levels of c-myc, erb B and EGFR mRNA increaaed respectively 3.5, 2.5 and 2.8 times in SCC when compared to normal tissues. In immunoperoxidase stain, EGFR was present, in SCC where keratinocytes with strong cyto-plasmic staining but no membr, line labelling, where as in normal skin the were primarily present in t,he membrane and cytoplasm of basal cells. In situ hybridization with c-myc cDNAs allowed detection of grains representative of biotin labelled cDNA-mRNA hybrids in the frozden section of SCC tissues. CONCLUSION: These results suggest that specific patterns of karyotypir abnormalites, rearrangement, or amplification of EGFR gene, and overexpression of oncogenes and EGFR gene may be associated with the carcinogenesis of SCC.

OBJECTIVE: This retrospective study aimed to compare clinical outcomes in terms of pain relief and recurrence rate between fragmentectomies and conventional microdiscectomies in patients with lumbar disc herniation (LDH). METHODS: Between January 2008 and May 2011, a total of 175 patients met the inclusion criteria of this study. The visual analogue scale (VAS) scores of back and radicular pains were recorded before surgery, 2 and 6 weeks after surgery. Recurrence was defined when a patient had the same pattern of preoperative symptoms and was confirmed with magnetic resonance imaging. RESULTS: Seventy-four patients (42.3%) were suitable for fragmentectomy, and 101 patients underwent conventional microdiscectomy. There were no significant differences in VAS scores between the fragmentectomy and conventional microdiscectomy groups 2 and 6 weeks after surgery. During the follow-up period, 3 patients (4.05%) in the fragmentectomy group and 7 patients (6.93%) in the conventional microdiscectomy group relapsed. CONCLUSION: If patients are selected according to well-defined criteria, fragmentectomy can be a good surgical option for LDH, in the physiological aspect of preserving healthy intervertebral disc materials.

BACKGROUND: Myocardial dysfunction after cardiopulmonary bypass (CPB) is a significant cause of morbidity and mortality after congenital cardiac surgery. The aim of this study was to evaluate myocardial function on sevoflurane anesthesia after CPB during ventricular septal defect repair. METHODS: Forty patients were randomly allocated into two groups: sevoflurane-fentanyl was used in group S, midazolam-fentanyl in group M. Myocardial performance index (MPI) and ejection fraction (EF) were measured by transesophageal echocardiography before incision and after operation. Serum cardiac Troponin-I (cTnI) levels were measured before incision, and at 0, 12, and 24 h after operation. RESULTS: MPI increased after operation in both groups (S: 0.35 +/- 0.06 vs. 0.43 +/- 0.05, M: 0.36 +/- 0.07 vs. 0.46 +/- 0.06 [P < 0.05]), but there was no significant difference between groups. EF decreased after operation in both groups (S: 65.1 +/- 5.5% vs. 62.7 +/- 3.9%, M: 64.9 +/- 5.3% vs. 61.4 +/- 4.4% ([P < 0.05]), but there was no significant difference between groups. cTnI was markedly elevated after operation, and decreased thereafter. There was no significant difference between groups. CONCLUSIONS: Both groups showed decreased myocardial function after CPB, but there were no difference between groups. Sevoflurane did not adversely affect intraoperative myocardial function compared to midazolam.
