Apert syndrome, or acrocephalosyndactyly is a complex of associated malformations, which are craniosynostosis and symmetric complex syndactyly of the hands and feet. The syndrome was first described by Apert in 1906. Review of the worlds literature disclosed about 200 similar cases and 9 Cases in Korea. Authors experienced one case of Apert syndrome and treated surgically for acro-syndactyly and polydactyly of both hands and feet. The case was compared with the other previously reported cases in Korea.

Hemorrhagic fever with renal syndrom is an acute febrile disease which is caused by Hantanvirus and several other viruses that belong to the genus Hantavirus. Gl and G2 glycoproteins of Hantanvirus have been thought to be involved in protective immunity against Hantanvirus infection. In this study, the antigenicity of G1 and G2 glycoproteins in cell mediated immune response was investigated. When peripheral blood mononuclear cell fraction from recovered hemorrhagic fever with renal syndrome patient was cultivated with a recombinant protein containing amino-terminal 78 amino acids of G2 glycoprotein, these cells were activated to proliferate and secreted significant amount of interleukin-2 and interferon-r. These results suggest that T cell epitope exists in the amino-terminal region of G2 glycoprotein.

The 56-kilodalton protein genes of Orientia tsutsugamushi TA678, TA686, TA716, TA763 strains were amplified by PCR. The amplified products were sequenced and cloned into pIH821 vector. The recombinant proteins were expressed in Escherichia coli as fusion proteins with maltose binding protein. The recombinant proteins were purified and used for the sensitization of sheep RBCs and the reactivity of the recombinant 56-kDa proteins of Orientia tsutsugamushi TA 678, TA686, TA716 strains were analyzed with 40 sera from scrub typhus patients in Korea, 40 sera from scrub typhus in Thailand, Malaysia and Philippines. The 56-kDa protein coding DNA sequence of Orientia tsutsugamushi TA678, TA686, TA716 show 70 to 88% homology with other known strains and four variable regions are also observed. 39 of 40 sera from scrub typhus patients in Korea showed the strongest reactivity to the recombinant protein of Boryong strain and one sera showed the strongest reactivity to the recombinant protein of Gilliam strain. 14 of 40 sera from patients in Thailand, Malaysia and Philippines showed the strongest reactivity to the recombinant protein of TA686 strain and 12 sera showed the strongest reactivity to the recombinant protein of TA716 strain. No serum from patients in Thailand, Malaysia and Philippines showed the strongest reactivity to the recombinant protein of Boryong strain.

BACKGROUND: Controversy exists as to whether or not inhalation anesthetics and intravenous anesthetics impair arterial oxygenation (PaO2) during one lung ventilation (OLV). Accordingly, we examined the effect of enflurane and propofol on PaO2 and pulmonary vascular resistance (PVR) during OLV. METHODS: Forty patients, who had prolonged periods of OLV anesthesia with minimal trauma to the nonventilated lung were studied in a cross over design. Patients were randomized to four groups; Group 1 received 1 MAC of enflurane and oxygen from induction until the first 20 min after complete lung collapse, then were switched to propofol 100 g/kg/min (P100). In group 2, the order of the anesthetics was reversed. Group 3, Group 4 received the same order of the anesthetics as Group 1, Group 2, respectively but received propofol 200 g/kg/min (P200). RESULTS: During OLV, the PaO2 values were lower than those with two lung ventilation (TLV), there were no significant differences among each groups and between propofol and enflurane in PaO2, but in the selected patients (n=10, PaO2<120 mmHg during OLV), PaO2 in propofol group was higher than that of enflurane group (p<0.05). Conversion from TLV to OLV caused a significant increase in PVR, but there were no difference in PVR between propofol and enflurane group. CONCLUSIONS: These results suggest that the usual clinical dose of propofol affords no advantage over 1 MAC of enflurane anesthesia except low PaO2 patients during OLV. Propofol might be of value in risk patients of hypoxemia during thoracic surgery when OLV is planned.

Double primary cancer is defined as the case of primary malignant tumors in one person, which must be arisen in different sites and have a different histologic appearances in each other. The number of reported cases of multiple primary malignant tumors has increased in recent years, because of more developed diagnostic procedure and long survival of cancer patients, We have experienced 4 cases of double primary malignant tumors which were stomach cancer with colon, bronchus and esophagus cancer, and report these cases with review of literatures.
