The teeth present at birth are called natal teeth, while the teeth that appear within the first thirty days following birth are called neonatal teeth. Approximately one in 2,000 to 3,500 infants experiences the eruption of teeth at birth or within the first few weeks postpartum. Many contributing factors have been suggested for the premature eruption of primary teeth. It has been suggested that upon eruption these teeth are of normal structure according to their developmental age, but after eruption, lateral movement in the cervical area leads to disturbance of the dentin and premature degeneration of Hertwig's root sheath. In most cases, they have immature, aborted structures consisting only of caps of enamel, dentin, or a combination of both. A radiograph can show the presence or absence of enamel, dentin, or root structures, as well as supernumerary teeth. These teeth may be aspirated or swallowed during feeding. Discomfort from mobile and erupting teeth often causes the infant to refuse to feed. In addition, a nursing mother's nipples may become lacerated and infected. Extraction is the indicated treatment if these neonatal teeth cause discomfort or demonstrate mobility or incomplete, immature development. Treatment decisions must be made on an individual basis from both clinical and radiographic findings. We report four cases of neonatal teeth in complete cleft lip and palate patients.

A clinical observation was made on the bladder tumors of the inpatients in the Department of Urology, Seoul National University Hospital during the period January. 1957 through June, 1967. During the period, of 1.836 cases (1,372 males and 464 females) hospitalized, 99 cases had bladder tumors, giving a rate of 5.3%. Among the 99 cases, 88 cases could be studied and the following results were obtained. 1. Among the 88 cases, 68 cases were male and 20 cases were female with ratio of 3.4 to 1. 2. Age distribution ranged from 22 years to 79 years, 70.5% of cases were in the age group of 4o~69. 3. Hematuria which occurred in 80 cases is the most common initial disturbance. The other common manifestations are frequency, dysuria and urinary retention as in order. 4. 54 cases or 61.5% of the cases visited to hospital within one year after the occurrence of initial disturbance. 5. 37.8% of the cases involved in the lateral wall, 30.7% in the posterior wall, 12.1% in the entire wall and 7.9% in the trigone. 6. As the methods of treatments, T.U.R. was performed 43 times, 29 time of electrocoagulation through suprapubic cystotomy and 12 times of partial resection of the bladder were done. 7. Among 88 cases, pathologic diagnosis was made in 72 cases. Transitional cell carcinoma is observed in 62 cases, adenocarcinoma in 4 cases, metastatic carcinoma in 3 cases and squamous cell carcinoma in 1 case. 8. 27 (30.7%) cases had had follow-up studies one or more times for 2 months to six and half years. At the first follow-up study 6 cases were tumor free and 21 cases had recurrent tumors.

Seidel nail is one of locked humeral nail and Seidel himself reported excellent result in his preliminary report using his nail. But our early experience showed disappointing result with high rate of complications, So we reviewed our 16 cases of humeral shaft fracture with polytrauma treated with Seidel nail and studied anatomical fitness of the nail within the distal medullary space using CT scan. The most frequent complication was intraoperative fracture of the proximal humerus < 4 cases> and this seemed to be due to lateral placement of pilot hole. There were 3 cases of nonunion and these cases showed insufficient distal anchorage, either primarily or postoperatively. Anatomical fitness study showed insufficient spreading of nail flanges in 5 cases of distal canal width below 9mm and nonunion cases were in this group. Other problems of Seidel nail were technical difficulties due to occasionally incorrect proximal targeting device and frequent breakage of adaptor screw. Study of more cases may be needed to confirm the design problem of Seidel nail.

We clinically analyzed 53 patients of fresh femoral neck fractures who were treated in Daegu Catholic Hospital from Aug. 1980 to Apr. 1987: The end results of the surgical methods, i.e. internal fixation, endoprosthesis and total hip replacement, were compared in the 45 patients who were followed for more than 2 years. The results were as follows. 1. The most frequent age occurrence was different in sexes ; male was in the 8th decade (29%) and female was in the 6th decade(31%). 2. The most frequent cause of fracture was “fell from height” in male(43%) and slip down in female(47%).3. Mid cervical fracture was the most frequent in anatomical classification(49%) and 83% of fractures were displaced(Garden stage III & IV). 4. The results were evaluated by the modified Lunceford criteria which included the degree of patient's own satisfaction. The combined result of “excellent” and “good” were obtained in 75% of 20 internal fixation cases, 80% of 15 endoprosthesis cases and 71% of total hip replacement cases. It was concluded that we could get similar results by 3 surgical methods if reasonable criteria of indication were applied for each method: rehabilitation of patient can more important than osteosynthesis itself in the determination of indication of operative methods.

The Inyo nail is a new intramedullary device for the treatment of the lateral malleolus. fracture of the ankle with the advantage of rigid fixation. The authors have experieced 16 cases of the Inyo nailing for the ankle fracture and fallowed more than 1 year in the 11 of them. Two groups of patients were evaluated; Group I was treated with the Inyo nail and Group II was treated by conventional technique. The following results were obtained; 1. The Inyo nail was suitable for treatment of type A & B fractures of the ankle. 2. Group I patients resumed their preinjury ROM of the ankles and activity earlier than Group II. 3. The results in the radiographic rating and fuctional criteria were excellent in those cases of Group I than those of Group II.

The symphysis pubis is a nonsynovial amphiarthrosis in which the bodies of the two pubic bones are united by a fibrocartilaginous disk. This forms subsidiary tie arches that augment femorsacral arch in the erect position, ischiosacral arch in the sitting position. In normal state the symphysis is strong enough not to be separated. We experienced 5 cases of separated symphysis pubis developed during labor at the Catholic Hospital from January 1987 to December 1988. The duration of follow-up was between 12 and 19 months without any residual symptom after conservative treatment.

A 46-year-old woman presented with multiple purpuric skin rashes together with splenomegaly and thrombocytopenia. The resected spleen weighed 720 gm, and contained multiple, discrete, dark red, bulging nodules throughout the entire splenic parenchyma. Microscopically, the nodules revealed various range of endothelial cell proliferation which included cavernous vasculature, anastomosing vascular channels, papillary intravascular growth and solid pattern. Intrasinusoidal sequestration of platelets along with extramedullary hematopoiesis was present in the neoplastic vascular spacws. Neither exposure to thorotrast nor vinyl chloride was nonfirmed. Ultrastructurally, the tumor cells demonstrated a row of pinocytotic vesicles, occasional intercellular junctional structures, and the paucity/absence of filamentous structures or Weibel-Palade bodies supports origin of sinus lining type cells. After splenectomy, the thrombocyte count returned to normal. We conclude this is the first case of primary splenic angiosarcoma with Kasabach-Merritt syndrome in Korean literature.

BACKGROUNDS: The inflammatory reaction after cerebral ischemia involving adhesion molecules aggravates neurologic deficit. This study aimed to study the change of plasma level of the adhesion molecules after acute cerebral ischemia. METHODS: Nineteen patients with acute cerebral infarction and ten control subjects without a history of cerebrovascular disease were included in this study. The patient groups were subgrouped into large artery atherosclerosis and small artery occlusion groups according to TOAST classification. Plasma levels of sP-selectin, sE-selectin, sICAM-1 and sVCAM-1 were measured within 24 hours and in 6 to 8 days after acute ischemic infarction. RESULTS: The plasma level of sP-selectin was elevated in acute stroke patients within 24 hours and in 6 to 8 days after stroke onset compared with control group(p<0.05). But plasma levels of sE-selectin, sICAM-1 and sVCAM-1 were not different from those of control group. The plasma level of sP-selectin was significantly elevated in large artery artherosclerosis group compared with control group. CONCLUSION: This study suggest that P-selectin actively involves in inflammatory process after acute ischemic stroke, especially associated with atherosclerosis.
