Changes in atlas position with Class II activator treatment in Class II malocclusion patients / 대한치과교정학회지

OBJECTIVE: Previous studies have reported that morphological features of the first cervical vertebra (atlas) have been associated with mandibular growth direction. The purpose of this study was to show the possible positional and morphological changes of the Atlas from activator treatment in Class II malocclusion patients. METHODS: Lateral cephalometric radiograph tracings were made at initial, middle and final stages of treatment. Angular and linear measurements of skeletal and morphological features were measured on the anatomical landmarks and reference planes. RESULTS: The skeletal effects of activator treatment on Class II malocclusion patients were evident on ramal height, body length, effective body length, ANB, and overjet. Clockwise rotation of the long axis of the Atlas was found in Group 1, but there was no inclination change of the Atlas in groups 2 and 3. There was no significant correlation between anterior and posterior positions of the atlas or morphological change in all groups. - except for posterior movements of the Atlas found in group 1. CONCLUSION: Clockwise rotation of the atlas axis resulted from activator treatment in Cl II malocclusion patients. Change in atlas axis can be thought of as an indicator for success of activator treatment.

Successive Suture Device for Gastrointestinal Endoscopes / 대한소화기내시경학회지

BACKGROUND/AIMS: Recently, treatment using an endoscopic device is actively being developed. Techniques for incision and bleeding control have been developed, but endoscopic suturing remains to be perfected. Using an endoscopic suturing technique, a variety of diseases could be managed noninvasively. We have attempted to use a new endoscopic suturing device which enables a continuous suture using a flexible upper endoscope. METHODS: A suturing device was designed where a semicircular needle could sew through tissue by rotation making a continuous suture possible. RESULTS: We successfully sutured the stomach tissue of a dog using an optimized suturing device model. CONCLUSIONS: The initial model was found to have some problems. However, we hope to develop a continuous suturing device for flexible upper endoscope procedures in Korea.

A Case of 2q-Syndrome 46, XX, del (2) (q33q35)

A long arm deletion of chromosome 2 is very rarely reported. Particular deletion uniformly resulted in developmental delays, craniofacial changes, and occasionally resulted in microcephaly, low set ears, and hand and foot abnormalities. We experienced a case of partial monosomy 2 in a 5-months-old girl, who showed low set ears, hypertelorism, low nasal bridges, small mouth, cleft palate, inguinal hernia. Chromosome analysis on a G banding with high resolution showed a deletion of the long arm of chromosome 2. Her karyotype was designated as 46, XX, del (2) (q33q35). A brief review of the literature is also presented.

6 Cases of Transient Hyperphosphatasemia of Infancy and Early Childhood

Sometimes physicians and clinical pathologists find very high levels of alkaline phosphatase (ALP) activity in their patients. This condition is associated with transient, marked increase in serum ALP in healthy infants and children. It has also been described in adults. Clinical and biochemical features of transient hyperphosphatasemia in infancy and early childhood are reviewed in six patients that we have studied. The diagnosis is suggested by findings of increased activity of alkaline phosphatase in plasma, typically more than fivefold the upper reference value for adult, in a child under five years of age, without evidence of liver or bone disease. The condition is confirmed by the presence of a characteristic pattern of alkaline phosphatase isoenzymes and by the normalization of enzyme activity in plasma within approximately six months after the original observation. The etiology of the condition and possible mechanism of the elevated ALP is discussed.

A Case of Familial beta-thalassemia Minor

Thalassemias are a diverse group of inherited anemias that are characterized by defective synthesis of one or more globin chains. The thalassemias are classified according to the globin chain or chains the synthesis of which is deficient : alpha-, beta-, delta beta-, delta-, and gamma delta beta- Thalassemia. They are common in the Mediterranean region, The Middle East, India, Burma, and Southeast Asia. Beta-thalassemia minor, the heterozygous state, is most frequently characterized by hypochrmia, microcytosis and an elevated percentage of hemoglobin A2. We experienced a case of a familial beta-thalassemia minor in pneumonia patient and his family.

The Clinical Study of 10 Cases of Tsutsugamushi Fever

In Korean, there has been an increasing concern on rickettsiosis as a possile common cause of unknown febrile illness since Tsutsugamushi fever among koreans was reported first in 1986. We experienced 10 cases of Tsutsugamushi fever ocurring in the Mokpo area during the period of 3 months (Oct, to Dcc.) in 1990, which were diagnosed clinically and serologically by indirect immunofluorescent antibody test. The following results were obtained. The most frequent symptoms were fever (100%), headache (90%), chill (60%), conjunctival injection, and lymphadenopathy. Common laboratory findings were leukopenia (WBC20mm/hr, 30%), positive CRP (60%), and elevated Alt/AST. Antibody titers against R. tsutsugamushi ranged from 1:80 to 1:1,280, but they showed no antibody reaction to Hantaan virus and leptospira. All patients showed good response to antibiotic therapy with chloramphenicol.

Hereditary Spastic Paraplegia

Hereditary spastic paraplegia is a familial disorder which is inherited by autosomal dominant, autosomal recessive or sex linked pattern. We experienced a family who has hereditary spastic paraplegia with mental retardation and extrapyramidal symptom that is thought inherited by autosomal dominant inheritance pattern. A review of literatures was made briefly.

Statistical Observation of the time of first stool and first void in 800 newborns

The statistical observation of the time of passage of the first stool and first void was performed on 800 cases of newborns, were carried at the newborn nursery and premature baby room, National Seoul Hospital, during the past two years from Jan, 1977 to Dec, 1978. The population study was performed on sex, gestational age, Apgar score, mode of delivery, and maternal disease or premedication during the pregnancy, congenital anomalies of the newborn infants. The results were as following. 1) The cases of passage of the first stool within 1 hour and 24 hours after birth were 15%, 96.9% of total boy and 12.4%, 97.1% of total girl in each cases. There were no remarkable differences in the time of first stool between the boys and girls. The cases of the first stool passage who was delayed until 48 hours of age were more frequent in boys(0.7%) than girls. The cases of the first voiding in the delivery room or within 1 hour after birth showed 8.2% of boys and 6.7% of girls and the cases after 24 hours of age showed 6.5%, 5.2%, relatively. This revealed that boys were more earlier than girls in their first voiding. 2) According to gestational age, a total of 98.5% and 94.5% of the fullterm infants had their first stool passing and voiding within 24 hours after birth. But 10.8% of preterm infants had their first stool just after birth and 2.4% of preterm infants had their first meconium after 48 hours of age. So this group tended to pass their first stool later than other groups of infants. And also 23.2% of postterm infants had their first stool just after birth and this group tended to pass their first meconium earlier than other group of infants. A total of 97.6% of preterm infants voided in the delivery room and 88.4% of postterm infants had urinated within 24 hours after birth. This showed that preterm infants tended to void early and the postterm infants tended to void later than other groups of infants. 3) According to apgar score, 41.7% of newborn infants with low Apgar score(score 0~4) had their first stool passage in the delivery room and 66.7% of low Apgar score group infants voided within 24 hours after birth and this group tended to pass their stool earlier and void later than high Apgar score group infants. 4) The delivery method did not influence to the general population in the time of first urination and stool passage. 5) The infants of preeclampsia or diabetic mother tended to void early and the infants born to mother who received diuretics during the pregnancy voided early also. The newborn infants who had combined with congenital anomalies of gastrointestinal tract or genitourinary tract were delayed the time of passage of the first stool or first urine.

A Case of Congenital Partial Anonychia

The congenital partial anonychia is known to be very rare developmental anomalies of the nail. Recently, we experienced a case of congenital partial anonychiain male newborn infant due to autosomal dominance. In this condition there complete absence of nails on the both thumb, index, middle fingers and toes were affected in a similar way to the fingers. But there were no other associated abnormalities. We present a case with a brief review of literature.
