Labial and buccal surface contours of Korean normal occlusion in a three-dimensional digital model / 대한치과교정학회지

OBJECTVIE: This study was performed to investigate the labio/buccal clinical crown curvatures of Korean permanent teeth and to obtain the curve-ratio data in an attempt to fabricate bracket bases fit for each individual Korean permanent tooth. METHODS: Three-dimensional digital models were made from 30 sets of dental casts with normal anatomic structures. According to the FA points, horizontal and vertical reference planes were established and lines were drawn on the tooth surfaces in reference to these planes. The curvature was expressed as the coefficient of a quadratic equation. Lines mesial, distal, gingival and occlusal to the horizontal, vertical reference planes and the FA point were drawn. RESULTS: The curvature measured for each line revealed that there are no significant differences between male and female, except for maxillary canines and maxillary second bicuspids (p > 0.05). There were notable differences in the mesio-distal or gingivo-occlusal curvatures among the mandibular lateral incisors, maxillary canines, maxillary and mandibular first and second bicuspids and first molars (p < 0.05). CONCLUSIONS: The labial & buccal crown curvatures of teeth in Korean normal occlusion were measured on the mesial and distal, gingival and occlusal sides respectively in this study. Based on these data, a SWA can be developed to fit the individual features of Korean tooth crowns.

A Case of congenital hydrocephalus associated with fetal intraventricular hemorrhage / 대한주산의학회잡지

Intraventricular hemorrhage is common in premature infants, and post-hemorrhagic hydrocephalus may follow. Rarely, intraventricular hemorrhage can occur in utero and may lead to congenital hydrocephalus. In most cases no underlying disease is identified. The fetus may be compromised by intrauterine hypoxia leading to hemorrhage. Fetal hydrocephalus can be identified by ultrasonography, but the hemorrhagic lesion can be identified with high sensitivity by magnetic resonance imaging. There are neurologic deficit in neonate with fetal hydrocephalus. Early surgical treatment is recommended for neurodevelopmental outcome. We experienced a case of congenital hydrocephalus associated with fetal intraventricular hemorrhage in our hospital. We report the case with a brief review of the literature.

Comparative study between pregnancies with and without hypertensive disorders in placental abruption / 대한주산의학회잡지

OBJECTIVE: The aim of this study was to compare the clinical characteristics of placental abruption according to the presence or absence of hypertensive disorders in pregnancy. METHODS: The retrospective analysis was performed in total 363 cases of placental abruption among 25,895 deliveries during 5 years from January, 2003 to December, 2007 in 8 hospitals of Catholic university in Korea. Maternal characteristics and neonatal outcomes were compared with parametric test. RESULTS: The incidence of placental abruption was 1.40% during the study period. The proportion of patients complicated with hypertensive disorders was 33.1%. There was no difference in maternal age and the number of previous pregnancy between two groups with or without hypertensive disorders. As expected, mean gestational age at delivery was lower in placental abruption with hypertensive disorders compared to those without the diseases (237.1 days vs 239.1 days). The incidence of abnormal fetal presentation, multiple gestation, PPROM, and polyhydramnios were more common in patients with placental abruption without hypertensive disorders. On the other hand, the incidence of maternal thrombophilia was significantly higher in patients with placental abruption with hypertensive disorders. The patients with placental abruption with hypertensive disorders had higher incidence of abdominal pain, fetal distress, uterine contraction, and uterine hypertonus (p<0.05). In terms of maternal complication, the patients with placental abruption with hypertensive disorders had more severe complications including shock, coagulopathy and renal failure (p<0.05) and had worse perinatal outcome including FDIU (fetal death in uterus) and neonatal death (10.8% vs 10.3%). CONCLUSION: In patients with placental abruption with hypertensive disorders in pregnancy, maternal complications were more common and prenatal outcome was worse compared to patients with placental abruption without hypertensive disorders.

Early Endometrial Cancer with Multiple Bone Metastasis / 대한산부인과학회지

A 61-year old female was found to have an endometrial cancer with surgical stage Ib, grade 2. Treatment involves surgical resection followed by radiation therapy. In the middle of adjuvant radiation therapy she complained of undifined headache and tongue deviation those came from multiple skull and skeletal metastasis. Although she received the adjuvant chemo-radiation therapy but failed. Therefore we reported a case of early endometrial cancer that unusually showed multiple bone metastasis with discussion about the pretreatment evaluation for bone metastasis.

A Case of Pruritic Urticarial Papules and Plaques of Pregnancy (PUPPP) Syndrome Supposedly Caused by the Paternity in Late Pregnancy / 대한주산의학회잡지

Pruritic Urticarial Papules and Plaques of Pregnancy (PUPPP) is a common dermatosis of pregnancy which usually occurs in the third trimester and generally in that of primigravida. Clinical feature is characterized by tiny erythematous papules which soon coalesce to form large, erythematous plaques. It generally occurs in abdomen, buttocks, thighs and upper inner arms. Since 1979 when Lawley et al. first described and reported PUPPP, there has been a lot of reports on PUPPP but the etiology is still not known. Many etiologic factors were reported but paternity as an etiologic factor was rarely reported. We had a very rare case which showed paternity could be one of the possible etiologic factors and we would like to share our case though this report.

Clinicopathologic characteristics and prognostic factors in adenocarcinoma of the uterine cervix / 대한산부인과학회지

OBJECTIVE: To evaluate clinicopathologic characteristics and prognostic factors in adenocarcinoma of the uterine cervix. METHODS: Medical records of patients with adenocarcinoma of the cervix who primarily underwent radical hysterectomy and pelvic lymphadenectomy (n=72) at A Hospital from August 1998 to July 2004 were retrospectively reviewed. Patients with stage IA1-IIB lesions were included in the study. Clinical and pathological data were reviewed and analyzed. RESULTS: Mean age at presentation was 46.5 years. The mean follow-up time for surviving patients was 35 months. The overall survival rate was 91.7% and disease free survival rate was 88.9%. Using univariate analysis, stage, lymph-vascular space invasion (LVSI), parametrial invasion, pelvic lymph node invasion and depth of stromal invasion were significant for survival, whereas grade, age, endometrial invasion were not significant. But using multivariate analysis, only stage and pelvic lymph node invasion remained significant independent predictors for survival. CONCLUSION: Our study demonstrates that survival rate is high for patients with early stage, after primary surgery. We found stage and pelvic lymph node invasion of significant prognostic value for survival in cervical adenocarcinoma.

Two Cases of Acute Interstitial Pneumonia During the Second Trimester of Pregnancy / 대한주산의학회잡지

We present two cases of acute interstitial pneumonia (AIP) during the second trimester of pregnancy managed by mechanical ventilation, high dose corticosteroids. We described clinical course, laboratory data and imaging studies. Case 1) A 29-year-old woman, G1P1, was referred for aggravated continuous coughing, sputum and dyspnea, pleuritic chest pain and mild fever for 3 weeks at 24(+3) weeks of gestation. There were coarse breathing sounds with crackles on the both lung field. Her chest X-ray showed diffuse haziness in both lungs with suspicious nodular opacities and suggested pneumonia. HRCT showed diffuse ground glass opacities with interstitial thickening and suspicious fine nodular infiltration in both lungs suggesting acute interstitial pneumonia combined with ARDS. Because her symptoms were more aggravated, she was performed mechanical ventilation treatment. After that, she was performed cesarean hysterotomy and delivered a dead male 850grams. After her symptoms were much more improved. All antibiotics were stopped and reduced the doses of steroids, she was discharged with t-tube capped state. Case 2) A 33-year-old woman, G1P1, was referred for continuous coughing, sputum and dyspnea for 3 months and low abdominal discomfort at 24(+4) weeks of gestation. There were coarse breathing sounds with rales on the both lung field. Her chest X-ray showed diffuse haziness in both lungs with suspicious nodular opacities and suggested interstitial pneumonia. HRCT showed diffuse ground glass opacities with some intralobular and interlobular interstitial thickening and suspicious fine nodular infiltration in both lungs suggesting acute interstitial pneumonia or miliary TBc combined with ARDS. She was treated with antibiotics, oxygen, high dose corticosteroids, and tocolytics. There was no evidence of TBc in the bronchoscopy. She showed decreased mentality and decreased O2 saturation below 90% in spite of mechanical ventilation, high dose steroids and IVGV therapy. She delivered a boy of 870 g (Apgar score 1/5). After delivery, she was expired due to combined aggravating DIC. Her baby was expired at the next day, too. The outcome of AIP is fatal, reporting 59~100% mortality rate. The clinical course, laboratory data and treatment are not well established due to rarity of this disease entity. Chest X-ray and HRCT may be helpful in diagnosis and high dose steroid and immunosuppressive agents usually used but the efficacy is not guaranteed.
