The palatal fracture results in deformity of the midface, as well as change in occlusion. However, no report was found on the incidence, treatment and results of palatal fracture in Korea. A retrospective review was done over 6 years and 11 patients(6.5%) with palatal fracture were determind out of 168 patients who had midfacial bone fractures without nasal bone fracture. According to the Hendrickson's classification, the number of patients with specific types of palatal fracture was described as follows; sagittal (2 cases), parasagittal (2 cases), para-alveolar (3 cases), transverse(3 cases) and complex(1 case). Le Fort I (6 cases), Le Fort II (7 cases) and mandible (6 cases) fractures were also associated. Open reduction and internal fixation was applied to all patients. Internal fixation consisted of pyriform or alveolar ridge stabilization and maxillary buttress stabilization. The rigid palatal vault stabilization was applied in one patient with midline split of the palate. The duration of intermaxillary fixation was shortened to less than 3 weeks from 4 to 6 weeks with rigid fixation. The palatal splint was used temporarily before internal fixation. All the patients showed good bony union and satisfactoryocclusion postoperatively. Open reduction and internal fixation showed satisfactory results from the aspects of stability, occlusion, patient convenience and final aesthetics. The following treatment model for palatal fracture according to the fracture type is proposed; 1) Alveolar type - close reduction or open reduction and selective alveolar ridge fixation and selective application of palatal splint, 2) Sagittal type - open reduction and internal fixation of the alveolar ridge, maxillary buttress and palatal vault. 3) Parasagittal type - open reduction and internal fixation of the pyriform aperture and maxillary buttress, as well as selective fixation of the palatal vault. 4) Para-alveolar type - open reduction and internal fixation of the alveolar ridge and maxillary buttress. 5) Complex type - open reduction and internal fixation of the alveolar ridge, maxillary buttress, pyriform aperture and continuous use of a palatal splint to bony union. 6) Transverse type - open reduction and internal fixation of the alveolar ridge and maxillary buttress.

Parameters of the left ventricular performance were evaluated by echocardiographic examination in 66 normal subjects. Effects of pulse rate, systemic arterial pressure, peripheral resistance and left ventricular end-diastolic dimension on the parameters were also observed. Normal value(mean+/-SD) of fractional shortening was 34.0+/-5.2%, ejection fraction 0.71+/-0.07, mean rate of circumferential fiber shortening 1.15+/-0.19 circ/sec, mean posterior wall velocity 4.05+/-0.70cm/sec, maximal posterior wall velocity 6.31+/-1.26cm/sec, mean normalized posterior wall velocity 0.82+/-0.14/sec, and maximal normalized posterior wall velocity 1.28+/-0.24/sec. There were negative correlations of peripheral resistance to fractional shortening, ejection fraction and mean rate of circumferential fiber shortening. Pulse rate and left ventricular end-diastolic dimension did not have significant effects on these parameters. Mean and maximal posterior wall velocity had negative correlations to peripheral resistance and positive correlations to left ventricular end-diastolic dimension. But mean and maximal normalized posterior wall velocity had no correlations to any of them.

TO determine the normal neonatal adrenal gland size, ultrasonographic examinations were performed in 145 newborn infants. They were divided into 3 groups according to the days of age. The group I is 1~3 days, group II is 6~9 days and group III is 21~50 days of age. 1) The adrenal gland size was as follows. In group I, the length was 29.05mm and the width was 4.02mm. In group II, the length was 24.04mm and the width was 2.79mm. In group III, the length was 19.54mm and the width was 2.21mm. 2) With increasing age, the size of adrenal gland became smaller. 3) The size of adrenal gland correlated well with the birth weight and height. We conclude that the ultrasonographic examination is useful in infant adrenal gland disease.

Iron deficiency remains the most common cause of anemia in infants and chidren despite increasing availability of iron-fortified foods. We screened out anemia in 9-month old infants in well baby clinic to know the prevalence of anemia and the weaning status. The results were as follows: 1) Among 345 infants screened, 24 infants (7%) were found to have anemia. 2) The kind of anemia was microcytosis and 7 infants (2.2%) revealed hypochromia. 3) Among the remaining 311 non-anemic infants, 6 infants (1.9%) revealed microcytosis and 7 infants (2.2%) revealed hypochromia. 4) In anemic group the mean hemoglobin concentration was 8.75+/-1.03gm/dl, hematocrit was 27. 73+/-3.11%, MCV was 65.84+/-8.21 fL, MCHwas 20.95+/-2.93 pg and MCHC was 31.34+/-1.89 gm/dl. 5) In 9 anemic infants, weaning was delayed until 9 months of age.
