The femoral neck in children is dense and is small in diameter and its periosteum is thicker and stronger than that of an adult. Thus, fractures of the femoral neck in children, unlike the 60-year-old woman, are rare and usually require severe violence and this accounts for the high frequency of associated injuries. Since these fractures are rare and the femoral neck in children has many anatomic and physiologic differences, we have to consider some factors that work against treatment of these fractures. Twenty seven cases of fractures of the femoral neck in children which were treated at Severance Hospital, Yonsei University College of Mediicne from Jan. 1971 to Dec. 1980 were analyzed both clinically and radiologically and the following results were obtained. 1. Among the 27 patients, the ratio of boys and girls was 2:1 and the highest incidence was between the ages of 3 and 5 years. 2. The main course of fractures was traffic accidents, 14 cases (51.9%) and the other causes were falling from a height (37.0%) and a few cases of a slip and a fall. 3. According to the classification of Delbet and Colonna, the cervico-trochanteric fracture (40.8%) was the commonest type and 13 cases (48.1%) were displaced fractures. 4. Common associated injuries were pelvic bone fractures, skull fractures, cerebral concussion and soft tissue injuries. 5. Fifteen cases (55.6%) were treated by conservative treatment and ten cases (37.0%) by closed reduction & internal fixation. 6. 23 of the 27 cases were followed for from 6 months to 10 years, average 19 months. The results were analyzed according to Ratliffs assessment and 14 cases (60.9%) showed good results. 7. Total cases with complications were 14 (60.9%), the commonest complication being coxa vara (40.8%) and the other main complications being premature epiphyseal closure (39.1%) and avascular necrosis (30.1%). 8. Secondary treatment was done in 6 cases and correction osteotomy was done in 4 cases which had showed a poor result. 9. Finally, factors affecting results were type of fracture, degree of displacement, maintenance of reduction, interval between injury and treatment, complications and patients age. 10. The authors recommend closed reduction and internal fixation with some threaded pins for all type II and type III fractures.

BACKGROUND: There have been no studies of airway management strategies for difficult intubation and cannot intubate, cannot ventilate (CICV) situations in Korea. This study was intended to survey devices or methods that Korean anesthesiologists and intensivists prefer in difficult intubation and CICV situations. METHODS: A face-to-face questionnaire that consisted of a doctor's preference, experience and comfort level for alternative airway management devices was presented to anesthesiologists and intensivists at study meetings and conferences from October 2014 to December 2014. RESULTS: We received 218 completed questionnaires. In regards to difficult intubation, the order of preferred alternative airway devices was a videolaryngoscope (51.8%), an optical stylet (22.9%), an intubating laryngeal mask airway (11.5%), and a fiber-optic bronchoscope (10.6%). One hundred forty-two (65.1%) respondents had encountered CICV situations, and most of the cases were identified during elective surgery. In CICV situations, the order of preferred methods of infraglottic airway management was cricothyroidotomy (CT) by intravenous (IV) catheter (57.3%), tracheostomy by a surgeon (18.8%), wire-guided CT (18.8%), CT using a bougie (2.8%), and open surgery CT using a scalpel (2.3%). Ninety-eight (45%) of the 218 respondents were familiar with the American Society of Anesthesiologists' difficult airway algorithm or Difficult Airway Society algorithm, and only 43 (19.7%) had participated in airway workshops within the past five years. CONCLUSION: The videolaryngoscope was the most preferred device for difficult airways. In CICV situations, the method of CT via an IV catheter was the most frequently used, followed by wire-guided CT method and tracheostomy by the attending surgeon.

Three cases of successful pregnancy outcome after intensive care in the patients with rare mullerian anomaly of complete uterine septum, hypoplastic cervical duplication and longitudinal vaginal septum in infertility clinic are reported. These presented three cases are the reports of supporting the embryologic hypothesis of bidirectional mullerian development which fusion and resorption begins at the isthmus and proceeds simultaneously in both the cranial and caudal directions rather than the classical views of unidirectional(caudal to cranial) mullerian development. Thus, we present here three cases of rare mullerian anomaly and their pregnancy outcomes in an attempt to alert gynecologist to the possible occurrence of such a malformation. In 2 cases, successful pregnancy outcomes were achieved after abdominal or hysteroscopic uterine septotomy before pregnancy and in the last case, successful pregnancy outcome intensive obstetric care was achieved even under uncorrected uterine anomaly and complete removal of uterine septum resulted in uneventful postoperative courses at the same time of cesarean section.

In our previous study, we observed that hydrosalpingeal fluid (HSF) adversely effect mouswe embryo development and hatching. The aim of this study was to evaluate the effect of HSF as assessed by the blastocyst development rate (BDR) and by cell counting in vitro HSF was collected from nine patients undergoing salpingoneostomy to correct hydrosalpinx. Two-cell embryos were obtained from superovulated ICR mice. T6 medium and T6+/-0.4% bovine serum albumin were used as control media. T6 medium containing 10% or 50% HSF and 100% HSF from each patient were used as test media. Nine to 15 embryos were cultured in microdrops prepared from each of these media. To assess the total cell number within each blastocyst, the blastocysts were fixed and stained with Hoechst 33342 to facilitate cell counting. The mean BDR in two control media were 88.89% and 85.40%. The mean BDR in media containing 10%, 50%, 100% HSF were 85.87%, 89.58% and 75.57%, respectively (*: p<0.05). The overall mean cell count (+/-SEM) in control media were 87.6+/-9.65 and 90.12+/-11.38. The BDR was affected adversely only by 100% HSF and not in media containing 10% or 50% HSF. Mean cell counts were decreased significantly only in blastocysts cultured 100% HSF (63.8+/-13.66; p<0.01) but not in blastocysts cultured in 10% or 50% HSF (91.3+/-12.44 and 82.9+/-18.27, respectively). Thus, it is concluded that HSF has no embyotoxic effect but has a mildly negatively effect on embryonic growth and development.

OBJECTIVES: The purpose of this study was to determine whether or not the shed endometrial tissues in menstrual fluid (MF) have adhesive potentials, using human amniotic membrane (AM). METHODS: The MF from 20 patients with regular menstruation was collected with Wallace catheter by aspiration from the uterine cavity on the second or third day of the menstrual period. The AM was obtained from the placenta of term delivery without any complication. The MF was washed and diluted fivefold with Hams F-10 medium supplemented with 10% fetal bovine serum. The cell suspension was placed on either epithelial layer (EP) or extracellular matrix layer (ECM) of the AM. After 5 days of culture, the adhesion sites were observed under a stereomicroscope. For histological observation, each cultured AM was prepared for the serial paraffin section. RESULTS: The adhesion sites of endometrial tissues in MF were found both ECM (20/20) and EP (11/20) of the AM. The size of adhesion sites in each AM were highly variable from microscopic to macroscopic size. CONCLUSION: We found that the shed endometrial tissues in MF have adhesive potential to epithelial layer in addition to extracellular matrix layer of amniotic membrane. This adhesive potential may be related to pathogenesis of endometriosis. We suggest that this culture system can be useful as an in-vitro model for endometriosis.

OBJECTIVES: The most common chromosomal abnormality contributing to recurrent abortion is the balanced chromosomal translocation. However the exact incidence of fetal losses are still unknown. The objectives of this study were to evaluate the incidence of fetal chromosomal abnormalities and outcome of pregnancy in recurrent miscarriage couples with balanced translocation. DESIGN: A retrospective analysis of recurrent spontaneous abortion patients with balanced chromosomal translocation. MATERIALS AND METHODS: Cytogenetic analysis was performed in 56 couples with history of recurrent abortions from 1995 to 1999. The use of high resolution banding technique and fluorescent in situ hybridization (FISH) in the chromosomal analysis has made the precise evaluation of chromosome aberrations. RESULTS: Among 56 couples, 42 patients had reciprocal translocation and 14 had Robertsonian translocation. Chromosomal aberrations were more frequent in women (36 cases) than in men (20 cases). Prenatal cytogenetic analyses were carried out in 14 subsequent pregnancies for carrier couples with balanced translocation. The fetal karyotypes showed that 5 cases (35.7%) was normal, 8 (57.1%) were balanced translocation, and 1 (7.1%) was unbalanced translocations. And cytogenetic analyses were done on 15 subsequent chorionic villi samples of abortuses for carrier couples with balanced translocations. Fourteen of fifteen abortuses (93.3%) were abnormal karyotype. CONCLUSIONS: Although the incidence of chromosomal imbalance in the fetuses was relatively low in prenatal cytogenetic analysis, individuals with balanced translocations are predisposed to giving birth to malformed offsprings with chromosomal imbalance (partial trisomy or monosomy). Therefore we recommend preimplantation genetic diagnosis (PGD) for recurrent abortions with balanced translocation and preventing the birth of offspring with chromosomal abnormalities.

The aim of this study was to evaluate the efficacy of intravenous immunoglobulin treatment for recurrent spontaneous abortion. Immunologic causes in either alloimmune or autoimmune type have been suggested for more than 80% of these patients. Various immunotherapy including paternal leukocyte transfusion has been used, but there is controversy on its efficacy and side-effects. The proposed immunomodulatory mechanism of intravenous immunoglobulin includes passive transfer of blocking or anti-idiotype antibody, blockade of Fc receptors, enhancement of supressor T-cell function, down regulation of B cell function. In this study, we used intravenous immunoglobulin for the prevention of spontaneous abortion. Five patients with a history of two or more spontaneous abortions were enrolled in this study. Other etiologic factors such as anatomical, chromosomal, hormonal factors were excluded. Three of them were positive for anti-cardiolipin antibody (ACA). When the pregnancy was diagnosed at about five weeks of gestation, 30 g intravenous immunoglobulin was administered and continued up to 28 weeks with three weeks. Ongoing pregnancy beyond 20 weeks was considered successful. Four among five patients (80%) was successful in maintaining pregnancy now ongoing 20, 31, 33, 39 weeks. One patient with ACA positive had abartion due to anembryonic pregnancy. No adverse reaction was observed during the treatment. From these preliminary data, it is suggested that intravenous immunoglobulin treatment may be effective in maintaining pregnancy in patients with unexplained recurrent spontaneous abortion, Further studies are needed to clarify the its immunomodulatory mechanism and establish a more simplified protocol limiting the use at certain critical period of time.

The purposes of the study was to examine changes in thickness and strength of the rat femur after administration of sodium fluoride in the drinking water. 48 female Sprague-Dawley rats were randomly divided into 4 groups, and they were supplied with 0(control), 1, 5 and 50 ppm of fluoride in the drinking water ad libitum for 6 weeks. Rats were killed and both sides of femur were dissected. Bone strength was measured as the stress of failure of femur at the middle point and femoral neck with Instron. Histologic slides were prepared from the femur shaft with routine processing of fixing, demineralizing, embedding and HE staining. Thickness and area of cortical bone and medullary cavity were measured by using Camera Lucida and Image Analyzer. All the collected data were analyzed with one-way ANOVA, Duncanos multiple range test for post-hoc tests and ANCOVA using the SAS 6.12 package at the level of 0.05. Bone strength increased significantly in the animals given 1 and 5 ppm of fluoride in the water, as compared to the control group. There were significant decreases of stress at fracture in 50 ppmF group compared to the 1 and 5 ppmF groups. The similar trends of bone strength at the femoral neck fracture test, but there were no statistical significances. Cortical bone thickness and area of the femur increased in the 1 and 5 ppmF groups compared to the control. However, the thickness of 50 ppmF group also decreased significantly as compared to 1 and 5 ppmF groups. On the other hand, medullary thickness and area increased in all fluoride groups than control group. All of the findings presented support the conclusion that, low fluoride dosage used in water fluoridation could increase the bone strength and might have preventive effect on femur fracture.
