Digital intraoral impression for immediate provisional restoration of maxillary single implant: A case report / 대한치과보철학회지

Developing of digital technique, it is possible to fabricate implant prostheses for edentulous area using intraoral 3-dimentional information throughout implant diagnosis and treatment process. It is being changed that from the method using CAD/CAM, producing prostheses by model scanning after conventional impression and model processing, to the method of fabricating implant provisional restorations and customized abutments by digital impression after connecting digital impression copings (scanbody) and implant fixtures without models. But, this digital method has not been actively used for implant prostheses not yet. Specially, it is short of intraoral digital impression cases for immediate provisional restorations of the maxillary anterior implants. The gingival contour impression of maxillary anterior area is very important for esthetic restorations. Accordingly, in this case report, the using a digital impression coping (scanbody) and digital impression by CEREC Omnicam (Sirona, Bensheim, Germany) or Trios (3shape, Copenhagen, Denmark) were introduced for immediate provisional restorations in 3 cases needed a single implant restoration in maxillary anterior area. The clinical results were satisfactory on the convenience and accuracy of digital impression technique and the good esthetics of final restorations.

A Study about Optimal Dose of Aspirin in Treating Kawasaki Disease

PURPOSE: A prospective study was performed to evaluate the efficacies of two different dosages of aspirin(ASA) in treating Kawasaki disease(KD). METHODS: Thirty-nine children with KD were admitted to this hospital from July, 1992 to May, 1993, and were assigned randomly into 2 groups. Group A(medium-dose group, 20 patients) was given 50mg/kg/d(# 4), and group B(high-dose gorup, 19 patients) was given 100mg/kg/d(# 4) of ASA. Intravenous gammaglobulin(2g/kg) was given to all patients. RESULTS: 1) There were no significant differences in ages, sex ratios, durations of fever before treatment, and laboratory findings on admission between two groups. 2) The durations of ASA administration were similar in 2 groups(group A, 10.1+/-2.77 ; group B, 10.6+/-3.37 days ;?p>0.1). 3) The durations of fever after onset of treatment were not different significantly (group A, 2.65+/-3.28 ; group B, 1.74+/-1.52 days ; p>0.1). 4) There were no significant differences in laboratory findings after treatment between two groups, except hemoglobin(Hgb) and ESR examined in the 3 rd week of illness (Hgb: group A (N=15), 10.1+/-1.24 ; group B(n=14), 11.1+/-0.92g/dl ; p0.1), and in 25% of group A(5/20) and 10.5% of group B(2/19) at the 2 nd examination (p>0.1). In long-term follow-up, only 1 patient in each group showed coronary aneurysm respectively. CONCLUSIONS: Although serum concentrations of ASA were different significantly, there were no significant differences in recovery from KD and incidences of coronary artery lesions between two grous. So we think medium-dose aspirin therapy is safe and effective in the treatment of Kawasaki disease.

Epidemiologic Study during 1993 Measles Outbreaks in Seongnam Area

PURPOSE: Although remarkable progress has been made in efforts to control measles since measles vaccines became available for use, the longterm success of their vaccination programmes has been questioned, with the worldwide resurgence of the disease. This resurgence has increased attention on the inadequacy of current immunization programmes. In 1993 there have been measles outbreaks in Seong-nam city located near the sourthern Seoul, Korea. To characterize further the epidemiology of measles in Seong-nam city, we analysed demographic characteristics of measles cases reported for the year 1993. METHODS: With the cooperation of the nurse teacher in elimentary school, the data of measles cases were collected and each case was confirmed at local clinics, hospital or general hospital, including inha General Hospital. RESULTS: 1) Out of 645 cases(male: female = 1.08:1) the children above 5 yrs of age were 586 cases of which 529 cases(90.3%) were vaccinated on after 15 months of age. After the survey, measles occurred in 1.9% of the 11 elementary school students. Children with past MMR vaccination history showed milder course of measles than those without the vaccination history. 2) Out of 87 patients who had been brought to Inha General Hospital, 55%(n=48) was 6 to 1 5 months of age, 13%(n=11) was 15 months to 4 years of age, and 32%(n=28) was 5 to 14 years of age, which showed two major outbreaks: those in which of the cases occurred below 16 months of age and those in which considerable cases occurred among school-age persons. 3) Below 15 months of age, most of the cause of the unvaccination were inadequate access to medical care and lack of public awareness in some communities, with the resulting lack of d emand for immunization services. The causes of unvaccination above 15 months of age were neglect or oblivion in 35%(n=2 0), mild acute illness not contraindicated to vaccine use in 21%(n=12), economic difficulty in 8. 8%(n=5), vaccine omission after natural measles before 12 months of age in 7%(n=4). CONCLUSIONS: Despite the high uptake of measles vaccine there is currently a nationwide e pidemic of measles, especially among the school-age groups. Secondary vaccine failure is also thought to be important cause of measles ortbreak as well as primary vaccine failure. A booster dose of measles vaccine may be necessary to reduce the measles outbreak to allow the goal of measles elimination to be achieved, with the reinforcement of age-appropriate Immunization.

A Case of Pulmonary Blastoma

Pulmonary blastoma is a rare type of malignant lung tumor comprised of epithelial and mesenchymal elements reminiscent of fetal lung. Mesenchymal element may show various patterns of differentiation toward mature tissue, such as cartilage, smooth muscle, and bone. Rhabdomyoblastic differentiation in pulmonary blastoma is quite rare. Our case of pulmonary blastoma with rhabdomyoblastic differentiation documented by electron microscopy and immunohistochemistry. Usually it has been treated with surgery, but both chemotherapy and radiotherapy have been used against the metastatic disease, and as the adjuvant setting. A 28/12-year-old girl is described who was presented with pulmonary blastoma. She underwent surgical excision of the tumor, followed by the T2protocol, a 8 cycles of combination chemotherapy consisting of actinomycin-D, adriamycin, vincristine and cyclophosphamide with the radiation therapy to the left chest cage(180cGyx11 times). The patient has been off therapy without any evidence of relapse for 24 months. We report a case of pulmonary blastoma with brief review of related literatures.

A case of hyperimmunoglobuline E syndrome

The hyperimmunoglobulin E syndrome is a primary immunodificiency disorder characterized by recurrent staphylococcal infections and markedly elevated serum IgE level. Clinical features are coarse face and severe infections of the skin-furunculosis or chronically pruritic dermatitis and sinopulmonary tract infection from infancy by coagulase positive Staphylococcus aureus, or Candida albicans etc. The patients's serum IgE level is elevated but the basic immunologic pathogenesis not fully understood. We have experienced a case of hyperimmunoglobulin E syndrome in a 26/12-year-old who had suffered from recurrent staphylococcal pneumonias and abscesses and chronically pruritic dermatitis from 1 month of age with elevated serum IgE level. A brief review of the related literature is presented.
