Abstract
The frequency of cleft lip with/without palate (CL/P) in the Mongolian population is approximately 1 in 1314 live births. This research aims to disseminate information about this congenital disability to the public to better understand CL/P, and people's fissures, and review administrative measures, as there is a lack of research in this area. A questionnaire survey was conducted using Google Forms, with 1000 Mongolian participants. Most participants (86.7%) said they had knowledge of the word, whereas 86.2% said they had knowledge of the condition. Most participants' answers were question-related disadvantages of CL/P patients, including statements such as "It's uncomfortable in human relationships" and "It makes an uncomfortable impression on the person you meet the first time." The results of this study revealed that most Mongolians were aware of CL/P and are concerned about patients. However, the causes of CL/P in the general population remain unknown, and further research is needed in this area.

Abstract
This study aims to identify potential variants in the TP63-IRF6 pathway and GREM1 for the etiology of non-syndromic orofacial cleft (NSOFC) among the Vietnamese population. By collecting 527 case-parent trios and 527 control samples, we conducted a stratified analysis based on different NSOFC phenotypes, using allelic, dominant, recessive and over-dominant models for case-control analyses, and family-based association tests for case-parent trios. Haplotype and linkage disequilibrium analyses were also conducted. IRF6 rs2235375 showed a significant association with an increased risk for non-syndromic cleft lip and palate (NSCLP) and cleft lip with or without cleft palate (NSCL/P) in the G allele, with pallele values of 0.0018 and 0.0003, respectively. Due to the recessive model (p = 0.0011) for the NSCL/P group, the reduced frequency of the GG genotype of rs2235375 was associated with a protective effect against NSCL/P. Additionally, offspring who inherited the G allele at rs2235375 had a 1.34-fold increased risk of NSCL/P compared to the C allele holders. IRF6 rs846810 and a G-G haplotype at rs2235375-rs846810 of IRF6 impacted NSCL/P, with p-values of 0.0015 and 0.0003, respectively. In conclusion, our study provided additional evidence for the association of IRF6 rs2235375 with NSCLP and NSCL/P. We also identified IRF6 rs846810 as a novel marker associated with NSCL/P, and haplotypes G-G and C-A at rs2235375-rs846810 of IRF6 associated with NSOFC.

Abstract
We have been conducting a survey on the birth prevalence of orofacial clefts, including cleft lip with or without cleft palate and cleft palate, in the Tokai area in central Japan every year for 37 years. Along with the yearly trends in the birth prevalence of orofacial clefts in that area for the past 37 years, we discuss whether the artificial abortion rate of fetuses with orofacial clefts has increased through the improved performance of ultrasonic imaging equipment. We also compare the yearly trends in the birth prevalence of congenital anomalies, including orofacial clefts, in Japan with those in other countries or areas where artificial abortion due to birth defects is legally permitted, and discuss the impact of improved accuracy of ultrasound imaging on the rate of artificial termination of pregnancy. The fact that the birth prevalence of orofacial clefts has basically remained unchanged for more than 30 years, even with recent more detailed prenatal diagnosis based on the improvement of ultrasonic diagnostic equipment, has allowed us tentatively to conclude that prenatal diagnosis is not currently threatening the right to life of the fetuses with orofacial clefts.

Abstract
Van der Woude syndrome (VWS) is an autosomal-dominant oral facial disorder. To find a gene mutation in a Japanese family using fingernail DNA samples, we performed this study. We hypothesized that a gene mutation in IRF6 might be involved in VWS, and that fingernail DNA samples may be valuable for detecting such mutations. Linkage and haplotype analyses of the family mapped the disease locus to the 1q32-q41 region. Mutation analysis with an improved extraction method for fingernail DNA detected a novel missense mutation (1046A>T, E349V) in exon 7 of IRF6 in all the affected members of the family. Since the E349V change may disturb the hydrophobic core and affect regulatory activity of IRF6, it is most likely that the mutation is causative for VWS in this family. Fingernail DNA is thus useful for linkage and mutation analyses, since the fingernail can be easily obtained non-invasively, sent through the mail, and stored for a long period. We emphasize here the usefulness of fingernail DNA for the genetic analysis of a disease.

Abstract
MSX1 has been proposed as a gene in which mutations may contribute to non-syndromic forms of cleft lip and/or cleft palate. Support for this comes from human linkage and linkage disequilibrium studies, chromosomal deletions resulting in haploinsufficiency, a large family with a stop codon mutation that includes clefting as a phenotype, and the Msx1 phenotype in a knockout mouse. This report describes a population based scan for mutations encompassing the sense and antisense transcribed sequence of MSX1 (two exons, one intron). We compare the completed genomic sequence of MSX1 to the mouse Msx1 sequence to identify non-coding homology regions, and sequence highly conserved elements. The samples studied were drawn from a panethnic collection including people of European, Asian, and native South American ancestry. The gene was sequenced in 917 people and potentially aetiological mutations were identified in 16. These included missense mutations in conserved amino acids and point mutations in conserved regions not identified in any of 500 controls sequenced. Five different missense mutations in seven unrelated subjects with clefting are described. Evolutionary sequence comparisons of all known Msx1 orthologues placed the amino acid substitutions in context. Four rare mutations were found in non-coding regions that are highly conserved and disrupt probable regulatory regions. In addition, a panel of 18 population specific polymorphic variants were identified that will be useful in future haplotype analyses of MSX1. MSX1 mutations are found in 2% of cases of clefting and should be considered for genetic counselling implications, particularly in those families in which autosomal dominant inheritance patterns or dental anomalies appear to be cosegregating with the clefting phenotype.

Abstract
The aims of this study were to determine the pathways of odontogenic infection spread into the submandibular space and their relationship to the clinical symptoms. Computerized tomography (CT) and magnetic resonance (MR) images of 33 patients with submandibular involvement were analyzed. The spread of infection was evaluated by lateral asymmetry of the shape and density of the fascial spaces and tissues, and by obliteration of the interfascial fat spaces. Imaging findings were classified into three types: in 19 patients (57.6%), infection spread through the mylohyoid muscle or sublingual space (type I). In five patients (15.2%), infection spread through the bony structures of the mandible with periosteal reaction or perforation of the cortical plate (type II) and was associated with relatively mild symptoms. In four patients (12.1%), infection spread from the masticatory space (type III). Seven of 11 patients with dysphagia or fever showed submandibular involvement spreading into the parapharyngeal space. CT and MR imaging clearly demonstrated different pathways of the spread of odontogenic infection into the submandibular space, which influenced the manifestation of clinical symptoms.

Abstract
STUDY DESIGN Pinealectomy induces experimental scoliosis in chickens. This study analyzed the correlation between the age at which pinealectomy was performed and the development of scoliosis in chickens. OBJECTIVE To investigate the differences in the rate or magnitude of scoliosis and the type of curvature in chickens pinealectomized at different times after hatching. SUMMARY OF BACKGROUND DATA Scoliosis develops in almost all chickens pinealectomized within 3 days after hatching, but there are no data on whether the condition will develop in chickens pinealectomized earlier or later after hatching. METHODS In this study, 106 female white leghorn chickens were divided into six groups: four pinealectomy groups (pinealectomy was performed 2, 4, 11, or 18 days after hatching in Groups P-2, P-4, P-11, and P-18, respectively), a control group (Group C), and a sham operation group (Group S). Ventrodorsal radiographs of the spine were taken at 4-week intervals until the age of 12 weeks. At 12 weeks, a 1-mL sample of blood was taken from the heart at the middle of the dark cycle, and the serum melatonin concentration was measured by radioimmunoassay. RESULTS At the age of 12 weeks, scoliosis was present in 63.6% of the chickens in Group P-2, 72.7% in Group P-4, 81% in Group P-11, and 70% in Group P-18, and the Cobb angles in the scoliotic chickens averaged 32.6, 29.8, 23.8, and 22.3 degrees in the respective groups. There were no significant differences in the rate or magnitude of scoliosis and the type of curvature among the pinealectomy groups at the age of 12 weeks. At the age of 12 weeks, the serum melatonin levels at the middle of the dark cycle in the pinealectomized chickens were significantly lower than those of chickens in Groups C and S. However, there were no differences in the serum melatonin levels between scoliotic and nonscoliotic pinealectomized chickens. CONCLUSIONS Findings from this study show that scoliosis develops in 60% to 80% of chickens pinealectomized within 18 days after hatching, and that scoliotic development is not influenced by the age at which pinealectomy is performed. However, this study suggests that melatonin plays a complicated role in spinal development, inasmuch as the serum melatonin levels after pinealectomy approximated zero. Yet scoliosis did not develop in all pinealectomized chickens.

Abstract
There have been many reports on congenital anomalies associated with cleft lip and/or palate (CL/CLP) in Japan. However, these reports included data only on patients who came to hospitals; thus the real situation regarding these anomalies remains unclear. Therefore, we surveyed newborns at all delivery facilities in the central area of Japan for the presence of these anomalies, following their progress for 12 consecutive years; at the end of that time, questionnaires were collected and analyzed. In this article, we describe our results.

Abstract
STUDY DESIGN The expression of cartilage-derived retinoic acid-sensitive protein (CD-RAP) was measured in cerebrospinal fluid from patients with spinal diseases. OBJECTIVES To quantify the levels of CD-RAP in human cerebrospinal fluid and to clarify its character. SUMMARY OF BACKGROUND DATA Cartilage-derived retinoic acid-sensitive protein is a newly discovered, secreted molecule that is expressed during the chondrogenesis phase of endochondral bone formation and in articular cartilage. In recent studies CD-RAP has been detected in the serum of patients with melanoma and breast cancer, and it has been used to monitor tumor activity. However, the function of CD-RAP is unknown, and the expression of CD-RAP in human cerebrospinal fluid has never been reported. METHODS The concentration of CD-RAP in human cerebrospinal fluid was measured by enzyme-linked immunosorbent assay with antihuman CD-RAP antibodies. Cerebrospinal fluid samples were collected from two groups of patients. Group 1, the control group, consisted of 40 patients: 22 with trauma and 18 with gynecologic diseases. Group 2 consisted of 172 patients with spinal diseases: 5 with meningioma, 5 with neurinoma, 5 with arachnoid cyst, 30 with cervical spondylotic myelopathy, 35 with lumbar disc herniation, 56 with lumbar canal stenosis, and 36 with scoliosis. RESULTS The concentration of CD-RAP in the control group was 16.5 +/- 8.3 ng/mL. The concentrations of CD-RAP in Group 2 were: 35.3 +/- 14.7 ng/mL in meningioma, 23.5 +/- 7.41 ng/mL in neurinoma, 26.0 +/- 22.2 ng/mL in arachnoid cyst, 41.7 +/- 22.3 ng/mL in cervical myelopathy, 27.8 +/- 14.7 ng/mL in lumbar disc herniation, 36.5 +/- 18.4 ng/mL in lumbar canal stenosis, and 13.4 +/- 7.48 ng/mL in scoliosis. The concentrations of CD-RAP in cervical myelopathy, lumbar canal stenosis, and lumbar disc herniation were significantly higher than in the control group (P < 0.001). CONCLUSIONS The CD-RAP concentration was low in the control group, whereas it was significantly higher in spinal diseases that cause spinal stenosis. CD-RAP is expressed in cerebrospinal fluid as a result of damage to or stressing of neural structures and could be a marker for spinal diseases.

Abstract
To investigate the incidence of cleft lip or palate or both (CLP) in Japan, 303738 babies born in 1532 institutions between 1994 and 1995 were examined and 437 (0.14%) were found to have abnormalities. Of these babies, 32.1% had cleft lip, 43.3% had cleft lip and palate, and 24.8% had cleft palate (Table 2). These results show that the incidence of cleft lip and palate has declined compared with the period from 1981 to 1982.

Abstract
Three hundred and six mothers who gave birth to babies with cleft lip, or palate, or both, were matched with 306 who gave birth to healthy babies in the same area during the same time period. Significantly more babies in the cleft group had a family history of clefts (48/306 compared with 7/306, P<0.0001). In the cases studied, combined cleft lip and palate was significantly more common among boys (82/157 compared with 57/149, P=0.02) and cleft palate alone among girls (48/149 compared with 22/157, P=0.0002). Significantly more mothers reported some sort of illness during early pregnancy (101/306 compared with 74/306, P=0.02). There were no differences between the groups as far as dietary preferences were concerned but during early pregnancy the mothers who gave birth to babies with defects tended to drink less alcohol (<1 unit/week) (236 compared with 199, P=0.001) and less coffee (<1 cup/week) (159/306 compared with 131, P=0.03). However, in each case similar proportions gave up once the pregnancy was confirmed. Large multicentre studies are required to confirm or refute these findings.

Abstract
Transforming growth factor-alpha (TGFA) has been proposed as a candidate gene in the etiology of nonsyndromic cleft lip with or without cleft palate (NS-CL/P) and of nonsyndromic cleft palate only (NS-CPO). Biologic support for a role of TGFA arises from its presence at high levels in the epithelial tissue of the medial edge of the palatal shelves at the time of shelf fusion in mice. Genetic support for the role of TGFA in clefting comes from the reported association of TGFA alleles with human NS-CPO and NS-CL/P. In this study we report the sequence and structure of human genomic TGFA and the search for causal TGFA mutations in 250 individuals with NS-CL/P or NS-CPO by conformational analysis of the coding sequence, splice junctions, and a portion of the 3' untranslated region strongly homologous between human and mouse. We confirm that human TGFA is composed of six exons and here report several new sequence substitutions and their frequencies. Five variants in conserved segments may represent rare causes for clefting in humans and provide support for the role of TGFA in facial morphogenesis.

Abstract
We performed the present study to identify those patients with adenocarcinoma of the cervix in whom ovarian preservation might be acceptable. Between January 1971 and December 1996, 82 patients with International Federation of Gynecology and Obstetrics stage IB and II cervical adenocarcinoma and adenosquamous carcinoma, treated by radical hysterectomy, bilateral salpingo-oophorectomy, and pelvic node dissection, were identified. The mean age of the patients was 44.6 years (range 27-72). The incidence of ovarian metastasis was more frequent in stage II (19.0%) than in stage IB disease (2.5%), in which only 1 patient with apparent extrauterine disease at laparotomy had an ovarian metastasis. No patients with up to inner two-thirds of stromal invasion had ovarian metastasis; however, 5 of 24 patients with outer one-third stromal invasion (20.8%) and 4 of 20 with parametrial invasion (20.0%) had ovarian metastasis. A significantly higher incidence of ovarian metastasis was also observed in 5 of 20 cases with lymph node metastasis (25.0%) than in 4 of 62 patients without lymph node metastasis (6.5%). Multivariate analysis, however, found only deep stromal invasion to be an independent risk factor for ovarian metastasis. Although it would be reasonable to conserve normal-appearing ovaries in young women undergoing radical hysterectomy for treatment of stage IB cervical adenocarcinoma and adenosquamous carcinoma, gross intraoperative inspection of the radical hysterectomy specimen may identify deep cervical invasion or extrauterine spread in those who are at increased risk of ovarian metastases.

Abstract
Oblique facial clefts constitute approximately 0.20% of all facial malformation cases in Japan and approximately 0.22% in other countries. In the present study, the proportion in our institute was approximately 0.21%, which is almost equal to that reported by WILSON et al. The ratio of male and female patients did not differ significantly from that in other countries.

Abstract
The A/J inbred strain of mice spontaneously develops cleft lip and/or palate (CL/P). Ovarian transplantation and several test-matings with C57BL/6 strain mice (0% CL/P) were performed to investigate a relationship between mother and fetus in regard to this order. The fetuses obtained showed that regardless of whether the genetic background of the mother was A/J or F1, CL/P was produced only in cases where the fetuses were genetically pure A/J. CL/P frequency was 7.46% in A/J fetuses developed in A/J mothers; it was 5.88% in F1 mothers with transplanted A/J ovaries. Isolated cleft palate (CP) and cleft lip with cleft palate (CLP) were found in A/J mothers. However, the frequency of CP was lower in F1 mothers than in A/J mothers. These results suggest that the occurrence of CLP depends more on the genetic constitution of the fetus than on maternal environmental factors, and the occurrence of CP was influenced by the mother's condition.

Abstract
A case of oblique facial cleft with supernumerary deciduous molars, probably caused by amniotic bands is reported. Besides facial cleft, and cleft palate and lip, there are sulci on the left side of the face and on the left posterior alveolar ridge. The sulci may be impressions of amniotic bands at a late gestational age and supernumerary teeth may also be related to these amniotic bands.

Abstract
We have already reported that the maxillary was markedly contracted 1 month after a cleft palate operation. Since we thought that this was mainly attributable to cicatrized contraction of the operation region, we prepared a palatal plate and inserted it from an early stage after palate plasty. In this paper we present our summarized findings on the use of the palatal plate. We report on its use both immediately after the operation, and for a period of 3 months after the operation. Its use in both cases is intended to prevent maxillary contraction following surgical treatment of the cleft palate.
