we studied the 12 patients, operated only sagittal split ramus osteotomy without genioplasty or maxillary osteotomy in department of oral and maxillofacial surgery, Hanyang university hospital from 1996.1. 1. to 1998. 7. 20. Preoperative and postoperative cephalometric view was measured to know the change of upper lip position and shape after mandibular setback. The result were obtained as follows. 1. The ratio of upper lip change amount to lower incisor horizontal movement was 15.1%. 2. The ratio of lower facial profile between Sn-Stm and Stm-Mes was changed from 1 : 2.352 to 1 : 2.069 after operation. 3. Post-operative upper lip was flattened 72.4% compared with pre-opreative one. 4. The vermilion zone of the upper lip increased 56% horizontally, 5.8% vertically after operation. 5. The vermilion zone ratio of the lower lip to the upper lip was change from 1 : 1.253 to 1 : 1.348. 6. The distance between esthetic line and Ls was changed from -3.958mm to -1.15mm.]]>

Malakoplakia is a chronic inflammatory disorder that usually affects the urinary tract in immunocompromised patients and rarely extends to adjacent organs. Due to its mass-like presentation, malakoplakia is often clinically misdiagnosed as a neoplastic lesion. We describe the case of a 51-year-old female with renal malakoplakia and hepatic extension and large intraperitoneal abscesses that had been misdiagnosed as malignancy. She was diagnosed with myasthenia gravis 12 years prior and had been treated with oral corticosteroids and immunosuppressants. Radical nephrectomy concomitant with abscess drainage was performed. The final pathology was compatible with malakoplakia, and the patient was successfully treated with antibiotics. Although renal malakoplakia is a rare disease, it should be included in the differential diagnosis of patients with a renal mass who have a history of recurrent urinary tract infections or evidence of immunosuppression.

PURPOSE: This study was carried out to investigate the awareness of the weaning of food using questionnaires, and the relationship with the weight gain in young infants. METHODS: From September 2005 to December 2005, we performed a survey on 141 guardians of young infants aged from 6 to 18 months, who visited the pediatric out-patient department at Dongguk University Medical Center. We calculated the total score for each responder from ten questions on the weaning of food and assessed the body weight percentile of each of the young infants. RESULTS: The most commonly reported information source for weaning food was 'the friends around' by 62 respondents (44.0%); 54 (38.3%) responded that the definition of weaning food was the preparatory step before starting a solid diet. Most used a spoon (90.8%) to feed when weaning food with a thin gruel of rice (78.7%). The time for weaning of food was before breast or infant formula feeding (55.3%). Addition of cow's milk was around 12 months (77.3%). The mean score was 6.21; however this did not show a statistically significant correlation with weight gain in young infants. CONCLUSION: The overall awareness of weaning of food has improved; however, information from doctors has decreased. Although the relationship between the awareness of weaning of food and the growth of young infants was not statistically significant, further studies on weaning of food, with larger and controlled sample sizes may provide important information.

The complement system is composed of more than 25 different proteins and is usually divided into classical and alternative pathways. Complement component 7(C7) is one of the five terminal complement proteins that, upon activation of either the classical or the alternative pathway, interacts sequentially to form a large protein-protein complex, called membrane attack complex(MAC). Assembly of the MAC on target cells results in the formation of transmembrane pores that can lead to the killing of the cells. C7 deficiency is an autosomal recessive disorder that is mostly reported in Caucasians. The gene for C7 has been assigned to chromosome 5p13. To date, 15 different molecular defects leading to total or subtotal C7 deficient defects have been reported. C7 deficiency is associated frequently with recurrently bacterial infections, especially meningitis caused by Neisseria meningitidis. We report a case of a hereditary C7 deficiency associated with meningococcal meningitis.

BACKGROUND: Essential thrombocythemia (ET) is a rare chronic myeloproliferative disorder characterized by an extremely high platelet count in the circulating blood and abnormal proliferation of the megakaryocytes in bone marrow, resulting in splenomegaly, thromboembolic or hemorrhagic complications. We studied the presence of nuclear hyperploidy of the megakaryocytes in bone marrow, the presence of abnormal response to the individual reagent on platelet aggregation test, and its clinical implication. METHODS: We analyzed the 43 cases of ET at the Asan Medical Center between January, 1989 and March, 1999. The Polycythemia Vera Study Group criteria were used to diagnose ET. RESULTS: Nuclear hyperploidy was observed at 43 cases (100%). Platelet aggregation test was done at 32 (74.4%) cases, of which 27 (84.4%) cases showed abnormal response to more than one reagent, 16 (50%) cases to more than two reagents. Abnormal response to epinephrine and collagen was most common, but 5 cases showed normal response. By individual reagent, 1 (3%) cases to adenosine diphosphate, 1 (3%) case to ristocetin, 22 (69%) cases to epinephrine, 19 (59%) cases to collagen showed abnormal response. CONCLUSION: We observe that nuclear hyperploidy of the megakaryocyts and abnormal response on platelet aggregation test are frequent in ET in this study.

OBJECTIVES: Rate of complete remission and long-term survival in adult acute lymphoblastic leukemia group has not been as satisfactory as that in childhood ALL. Recently introduction of induction chemotherapy of more intensive combination and various trials of postremission therapy are making improved results better looked forward to. And subtypes of ALL according to the degree of differentiation into T and B cells are identified by using immunologic markers hopefully to work out proper treatment for each subtype. METHODS: We analited results of treatment and differences of complete remission rate, remission duration and overall survival as to various immunologic markers and clinicopathologic characteristics in 33adult ALL patients. RESULTS: Eighty five percents of the 27cases that had VPDL chemotherapy achieved complete remission and both overall median survival and mediom duration of remission were 52weeks. No definite prognostic factors were detected influencing complete remission rate, remission duration and overall survival except that patients with serum albumin level higher than 4.0mg/dL showed highter complete remission rate. Although mature B-ALL showed the shortest overall median survival, degree of differenciation of B-cell and other immunologic markers did not influence on complete remission rate, remission duration or overall survival. CONCLUSION: Further studies are needed to delire the prognostic factors in adult ALL.

OBJECTIVES: Recently high dose chemotherapy with autologous peripheral blood stem cell transplantation (APBSCT) has been investigated with the hope of maximizing tumor response and increasing survival. The purpose of this study is to evaluate the effect, feasibility, and toxicity of high-dose cyclophosphamide, thiotepa, and carboplatin (CTCb) with APBSCT in patients with metastatic or high risk primary breast cancer. METHODS: Four cases of high-risk primary breast cancer (with more than 10 involved axillary nodes) and three cases of metastatic disease in complete or partial response were enrolled. Peripheral blood stem cells were mobilized by G-CSF plus chemotherapy, and median number of collected mononuclear cells was 5.44 X 108/kg(range, 1.95-7.08 X 108/kg). High-dose chemotherapy of cyclophosphamide (1,500mg/m2/day), thiotepa (125mg/m2/day) and carboplatin (200mg/m2/day) was administered for 4 days and peripheral blood stem cells were reinfused to the patients 72 hours after the completion of chemotherapy. RESULTS: The median days of recovery for neutrophil (over 500/mm3) and for platelet (over 50,000/mm3) were 10 (range, 8 to 33) and 30 (range, 10 to 40). One patient suffered from seizure attack and grade 3 hepatotoxicity during high dose chemotherapy, There were no treatment-related death. Four patients with high-risk primary breast cancer remained disease-free at 2, 8, 12 and 19 months post-transplant. In one patient with bone metastasis, complete response was induced following APBSCT. All three patients with metastatic disease remained progression-free at 8, 18 and 19 months post-transplant. CONCLUSION: High-dose chemotherapy and autologous peripheral blood stem cell transplantation was feasible and would be a potentially effective treatment modality in high risk and metastatic breast cancer.

Treatment-related myelodysplastic syndrome (t-MDS) and acute myelogenous leukemia (t-AML) are now well established as complications of cytotoxic chemotherapy. We experienced a 28-yr-old female patient who developed t-MDS/t-AML with characteristic chromosomal abnormalities including 11q23 chromosomal rearrangement following high-dose chemotherapy with autologous stem cell transplantation (ASCT) for non-Hodgkin's lymphoma. The patient was admitted with bulky abdominal masses of B cell lineage non-Hodgkin's lymphoma. After 2 cycles of systemic chemotherapy of the Vanderbilt regimen, the patient underwent ASCT with high dose chemotherapy of the BEAC regimen. She also received radiation of 48 Gy for the residual periportal lymphadenopathy. The initial cytogenetic analysis of the infused mononuclear cells revealed a normal karyotype. Twenty two months after the ASCT, pancytopenia was noted and her bone marrow aspirate showed dysplastic hemopoiesis with myeloblasts up to 12% of nonerythroid nucleated cells. The patient was diagnosed as t-MDS (refractory anemia with an excess of blasts). Cytogenetic analysis showed complex chromosomal abnormalities including 11q23 rearrangement, which is frequently found in topoisomerase II inhibitor-related hematologic malignancies. Four months later, it was noted that the t-MDS had evolved into an overt t-AML. Cytogenetic analysis showed an evolving pattern with more complex abnormalities. The patient was treated with combination che-motherapy, but her leukemic cells were resistant to the therapy.

BACKGROUND: It has been well known that normal leukocyte counts in blood can vary depending on age, gender, other environmental factors and ethnic differe nces. However, the normal white blood cell counts in Koreans has not been settled yet. Over past several years, a large number of patients were referred to the Hematology Clinic of Asan Medical Center (AMC) for evaluation of "leukopenia", and most of them were found to have no medical problems other than leukocyte counts less than 4,000/mm3. We performed this study on persons who visited Health Screening Center to analysis of leukopenic patients and also to establish the normal value of white blood cell counts in Korean. METHOD: We studied 31,307 persons (19,540 men, 11,767 women, aged 15-90), who visited to Health Screening Center of AMC during the period from January through December 1995. We have carried out retrospec tive analysis of complete medical record of 2,406 patients (838 men, 1,568 women, aged 20-81) who were found to have leukocyte counts less than 4,000/ mm3. And we tried to establish the normal values of leukocyte counts and differential counts of 24,079 adults (15,807 men, 8,272 women, aged 19-90), who were assessed to be healthy at Health Screening Center of AMC. RESULTS: 1) Leukopenia (WBC<4,000/mm3) were found in 2,406 subjects (7.7%) among 31,307 persons screened. 2) Among them, 77 subjects (3%) had medical illness; 39 of them had chronic B or C viral hepatitis, 24 of them had iron deficiency anemia, and other diseases were de tected in remaining 14 patients. But other hematologic dis eases or significant infectious diseases were not detected. Follow-up study of them has indicated no increased incidence of infection or other hematologic diseases. 3) The total white blood cell counts of 24,097 healthy Korean adults were 3,640-9,870/mm3 (5,900/ mm3) in men, and 3,270-8,400/mm3 (5,264/mm3) in women. Neutrophil counts ranged 1,288-6,866/mm3 (3,098/mm3) in men, and 1,180-5,985/mm3 (2,816/mm3) in women. Leukocyte counts were significantly lower in female, but no significant variation was found among age groups. CONCLUSION: Normal range of leukocyte counts and neutrophil counts of healthy Korean adults were lower than those of white populations. Thus, a new normal values of leukocyte and neutrophil counts should be established in Koreans. And many persons with leuko cyte counts less than 4,000/mm3 who are otherwise he althy could be normal.
