1/10. Orthodontic, genetic, and periodontal considerations in the treatment of impacted maxillary central incisors: A study of twins.Treatment of twins each with one impacted maxillary central incisor and a mesiodens is described. Treatment included rapid expansion, extraction of the mesiodens, surgical exposure of the impacted central incisor, and its forced eruption. The impacted incisor was brought into functional position in one patient but was lost in the other because of insufficient root length and high mobility. Orthodontic, genetic, and periodontal considerations of these 2 cases are evaluated.- - - - - - - - - - ranking = 1keywords = extraction (Clic here for more details about this article) |
2/10. prenatal diagnosis of meconium peritonitis in a twin pregnancy after intracytoplasmic sperm injection. A case report.BACKGROUND: meconium peritonitis occurring in pregnancies following artificial reproductive techniques (art) is rare. We report the first case of meconium peritonitis following intracytoplasmic sperm injection (ICSI). CASE: A 37-year-old woman attended our in vitro fertilization (IVF) program because her husband suffered from hypospermatogenetic azoospermia due to cancer surgery and radiotherapy. The patient achieved a twin pregnancy through ICSI from testicular sperm extraction at our IVF center. meconium peritonitis, fetal ascites, polyhydramnios, bowel dilatation, hydrocele and intraabdominal calcification were noted in one of the twins on ultrasound at 30 weeks' gestation. cesarean section due to breech presentation in labor was performed at 36 weeks' gestation. A normal female and male infant with a distended abdomen were delivered. Emergency laparotomy was performed on the male twin because of dyspnea. A 0.2-cm perforation was found in the terminal ileum. Ileotomy was performed and closed after 27 days. CONCLUSION: prenatal diagnosis of meconium peritonitis is possible through careful ultrasonographic examination, and early surgical intervention and intensive postoperative support are required to improve the prognosis.- - - - - - - - - - ranking = 1keywords = extraction (Clic here for more details about this article) |
3/10. Mandibular buccal bifurcation cyst: enucleation without extraction.The mandibular buccal bifurcation cyst (MBBC) is a cystic lesion, which occurs on the buccal surface of the permanent mandibular first molar in children around 6-8 years old. Treatment of the cyst has been controversial: extraction of the involved tooth and enucleation of the cyst, or only enucleation, without extraction. The aim of this article is to familiarize oral and maxillofacial surgeons with this entity and the appropriate treatment approach. The diagnostic features of MBBC are described and the treatment approach in five patients with a total of seven cysts is presented. Two cases were identified in identical twins. Enucleation of the cyst without extraction of the involved tooth is the treatment of choice when the available data and experience in treating MBBC are considered.- - - - - - - - - - ranking = 7keywords = extraction (Clic here for more details about this article) |
4/10. Case report: severe infraocclusion ankylosis occurring in siblings.AIM: This was to report a rare case of strong familiar tendency of ankylosis of maxillary second primary molars. CASE REPORT: Three Caucasian children, male twins of 8.5 years and a sister of 10 years, were diagnosed as having severely infraccluded maxillary second primary molars with underlying second premolars. In all three cases, the early extraction of the infraoccluded molars and an active treatment with cervical extraoral traction allowed the physiologic eruption of second premolars. Follow-up showed that normal vertical relationship and bone height had been obtained. CONCLUSION: early diagnosis, as well as appropriate treatment and careful follow-up are very important in the presence of severe infraocclusion, when the marginal ridge of affected primary teeth is at or below gingival level.- - - - - - - - - - ranking = 1keywords = extraction (Clic here for more details about this article) |
5/10. Generalized juvenile periodontitis: report of a familial case followed for 5 years.The case of a family, followed for 5 years and showing an exceptionally high prevalence of Generalized Juvenile periodontitis (GJP), is presented. Two siblings were affected by a severe form of GJP meanwhile the dycorial twin of one was periodontally healthy. Both the affected siblings showed infection by actinobacillus actinomycetemcomitans (Aa), but only one presented a reduced chemotaxis of the peripheral PMNs. The dycorial twin consistently displayed a freedom from Aa and a reduction in the peripheral PMNs chemotaxis. The extraction of the compromised teeth in the two affected siblings has been followed by colonization of new sites by Aa; only repeated administration of systemic tetracyclines seems to protect the subjects from colonization of other sites. These findings may contribute to the understanding of the etiology, pathogenesis, and therapy of juvenile periodontitis.- - - - - - - - - - ranking = 1keywords = extraction (Clic here for more details about this article) |
6/10. Corneal metastatic calcification in Werner's syndrome.We examined twin sisters with a clinical picture typical of Werner's syndrome. Both had undergone bilateral cataract extraction, one at 39 and one at 36 years of age, and had subsequently developed bilateral corneal metastatic calcification within a period of one to two years. In one twin, this keratopathy was associated with hypercalcemia. Each of the twins underwent penetrating keratoplasty in one eye, which was complicated by recurrence of metastatic calcification in a previously normal and clear corneal graft.- - - - - - - - - - ranking = 1keywords = extraction (Clic here for more details about this article) |
7/10. meningitis caused by streptococcus dysgalactiae in a preterm infant.This report describes a case of meningitis caused by a Lancefield group C streptococcus (streptococcus dysgalactiae) in a 9-week-old infant. bacteria of this group rarely cause serious infections in man. The organism was identified as a member of Lancefield group C by the acid extraction method and as S. dysgalactiae by biochemical tests. The patient's condition responded well to penicillin and tobramycin therapy, with no obvious neurologic sequelae.- - - - - - - - - - ranking = 1keywords = extraction (Clic here for more details about this article) |
8/10. dystonia in 61-year-old identical twins: observations over 45 years.We examined 61-year-old identical twin women of Jewish extraction with a probable autosomal recessive form of torsion dystonia. The dystonia in each was relatively mild and discovered only because a young relative developed dystonia. The twins were said to be discordant for dystonia, but personal evaluation led to the diagnosis of dystonia in both. Their slow course, with prolonged spontaneous remission in one twin, is in contrast to that described in most published reports. Although similar in mode of onset and initial course, the twins were dissimilar in age at onset, influence of pregnancy, diurnal variation in symptoms, need for medication, later course, and degree of disability at age 61. Normal plasma levels of norepinephrine and dopamine-beta-hydroxylase are consistent with autosomal recessive hereditary torsion dystonia. The importance of personal evaluation of key family members in establishing the correct genetic basis for a heterogeneous group of disorders, such as the hereditary dystonias, is stressed.- - - - - - - - - - ranking = 1keywords = extraction (Clic here for more details about this article) |
9/10. Class II, division 2 malocclusion. To extract--or not extract?Identical 13-year-old twin boys with Class II, division 2 malocclusions are treated at the same time, one with a full complement of teeth and the other with extraction of the first bicuspids.- - - - - - - - - - ranking = 1keywords = extraction (Clic here for more details about this article) |
10/10. Profile changes following extraction vs. nonextraction orthodontic treatment in a pair of identical twins.A pair of 11.5-year-old monozygotic twin boys--with a class I occlusion, deep bite and crowding in the lower arch--was presented for orthodontic treatment. One of them was treated in combination with extraction of 4 premolars while in the other the treatment was carried out without extractions. The superimposition of the pretreatment cephalometric tracings on the N-Pog line displayed minimal differences in the sagittal position of the incisors and no differences in the soft tissue profile. As a result of protrusion of the incisors in the nonextraction case and retrusion in the extraction case, a sagittal difference of 7.0 mm for the incision superius and 5.5 mm for the incision inferius was registered between the twins in relation to the N-Pog line at the end of treatment. However, the corresponding soft tissue differences were only 2.0 mm for the labrale superius and 3.2 mm for the labrale inferius and seemed to be reduced 1 year later.- - - - - - - - - - ranking = 12keywords = extraction (Clic here for more details about this article) |
