2/764. ST segment elevation in the right precordial leads induced with class IC antiarrhythmic drugs: insight into the mechanism of brugada syndrome.We evaluated two patients without previous episodes of syncope who showed characteristic ECG changes similar to brugada syndrome following administration of Class IC drugs, flecainide and pilsicainide, but not following Class IA drugs. Patient 1 had frequent episodes of paroxysmal atrial fibrillation resistant to Class IA drugs. After treatment with flecainide, the ECG showed a marked ST elevation in leads V2 and V3, and the coved-type configuration of ST segment in lead V2. A signal-averaged ECG showed late potentials that became more prominent after flecainide. Pilsicainide, a Class IC drug, induced the same ST segment elevation as flecainide, but procainamide did not. Patient 2 also had frequent episodes of paroxysmal atrial fibrillation. Pilsicainide changed atrial fibrillation to atrial flutter with 2:1 ventricular response, and the ECG showed right bundle branch block and a marked coved-type ST elevation in leads V1 and V2. After termination of atrial flutter, ST segment elevation in leads V1 and V2 continued. In this patient, procainamide and quinidine did not induce this type of ECG change. In conclusion, strong Na channel blocking drugs induce ST segment elevation similar to brugada syndrome even in patients without any history of syncope or ventricular fibrillation.- - - - - - - - - - ranking = 4keywords = record (Clic here for more details about this article) |
3/764. ophthalmoplegic migraine and periodic migrainous neuralgia, migraine variants with ocular manifestations.The spectrum of migraine has been outlined with particular attention to two entities: ophthalmoplegic migraine and Periodic Migrainous neuralgia. Although quite different in many respects from classical migraine, the relationship of a periodic localized vascular phenomenon giving rise to headache and transient neurologic signs, classify PMN and OPGM as migraine variants. Supportive of this concept, the literature has been reviewed in both entities, and some observations are made on the validity of earlier reports. It is the author's opinion that Raeder's syndrome should be reserved for patients with a lesion localizing in the paratrigeminal area. This does not exclude migraine as an etiologic agent but also recognizes tumors, infections and fractures as being more common.- - - - - - - - - - ranking = 0.78681656854233keywords = relation (Clic here for more details about this article) |
4/764. Temporary arterio-venous shunts to dilate saphenous crossover graft and maintain graft patency.A modification of the Palma operation is described in a 25-year-old man with impaired venous outflow of the right leg. After a phlebitic occlusion of the right superficial femoral and external iliac veins he had been operated on twice for varicose veins. The result of these operations was a serious outflow stasis of the right leg during exercise. A saphenous cross-over graft to the right popliteal vein was constructed. Preoperatively a temporary arterio-venous shunt between the left posterior tibial artery and the great saphenous vein had been made in order to increase the diameter of the saphenous vein. Three months later the dilated saphenous vein was resected at the level of the sapheno-tibial artery shunt and anastomosed to the popliteal vein of the right leg. The cross-over graft occluded several times during this operation. A temporary popliteo-popliteal arterio-venous shunt was established distally to the sapheno-popliteal anastomosis to keep the vein graft patent. This second arterio-venous shunt was resected after three months. Venography one month later showed that the vein graft was patent. The patient's complaints had disappeared one month after the operation and a normalization of his venous outflow was recorded plethysmographically. The graft has remained patent during an observation time of eighteen months.- - - - - - - - - - ranking = 1keywords = record (Clic here for more details about this article) |
5/764. Laryngeal paraganglioma in a five-year-old child--the youngest case ever recorded.A paraganglioma is a neuroendocrine neoplasm that originates from the paraganglion cells of the parasympathetic system. The average age of presentation is in the fifth decade. We report a case of laryngeal paraganglioma in a five-year-old child, the youngest case ever recorded. The features of paraganglioma which differentiate it from other tumours are also discussed.- - - - - - - - - - ranking = 5keywords = record (Clic here for more details about this article) |
6/764. Malignant melanoma of the ovary and exposure to clomiphene citrate: a case report and review of the literature.OBJECTIVE: The purpose of this article is to present a case of metastatic malignant melanoma of the ovary, a review of the current literature, and current recommendations for preventative and consultative management. STUDY DESIGN: This is a case report and literature review. A 34-year-old woman had symptoms of pelvic abscess 1 month after clomiphene citrate stimulation for infertility. After a failed course of antibiotic therapy, an exploratory laparotomy was performed. Bilateral malignant melanomas of the ovary were discovered. The patient died 4 weeks later of disseminated metastases. Retrospectively, a history of a "mole" with unknown histopathologic characteristics had been removed from her arm 15 years earlier. A review of the literature was performed to provide current findings regarding malignant melanomas of the ovary, as well as to evaluate the potential relationship between the use of ovarian stimulating drugs and the development of melanomas. RESULTS: Melanomas account for 3% of cancers, but the incidence of melanoma is rising. Genital melanomas are uncommon; the primary site is the vulva. Primary malignant melanoma of the ovary is rare; however, delayed recurrence from a primary skin site with metastasis to the ovary is documented. The literature suggests a possible relationship between the use of clomiphene citrate and an increase in melanomas of the skin. CONCLUSION: The gynecologist, as a primary provider, must be aware of the increasing incidence of malignant melanoma, as well as the recommendations for prevention. The gynecologist, as a consultant, must be aware of the risk of delayed recurrence of malignant melanoma. The potential for development of melanomas associated with the use of ovarian stimulation for infertility needs further monitoring and analysis.- - - - - - - - - - ranking = 1.5736331370847keywords = relation (Clic here for more details about this article) |
7/764. temporomandibular joint ankylosis: review of thirty-two cases.I have reviewed aetiology, sex, age at time of treatment, clinical features, radiographic findings, anaesthetic techniques, surgical treatment, complications, and results in 32 patients with ankylosis of the temporomandibular joint. Trauma and infection were the commonest causes of ankylosis: 50% and 41%, (n = 13), respectively. The 21-30 year age group had the most trauma cases. Twenty (63%) of the patients presented with bilateral ankylosis. Failing to do jaw-opening exercises was the main cause of relapse.- - - - - - - - - - ranking = 0.37597787444397keywords = jaw (Clic here for more details about this article) |
8/764. Long-term stability of mandibular orthopedic repositioning.Mandibular anterior repositioning appliances attempt to diminish temporomandibular joint pain, soft tissue noise, and myofascial discomfort by altering condyle-disc relationships. Secondary stabilization of the occlusion to this arbitrary anterior position through orthodontic tooth movement may significantly alter functional and muscular relationships. A case report is illustrated to show that as the functional environment attempted to reestablish equilibrium through adaptation, relapse occurred as the condyles "seated" posteriorly and superiorly toward their original relationship within the fossa. For all practical purposes, complete relapse of the orthodontic treatment result took place over time.- - - - - - - - - - ranking = 2.360449705627keywords = relation (Clic here for more details about this article) |
9/764. Treatment planning and biomechanics of distraction osteogenesis from an orthodontic perspective.As in traditional combined surgical and orthodontic procedures, the orthodontist has a role in the planning and orthodontic support of patients undergoing distraction osteogenesis. This role includes predistraction assessment of the craniofacial skeleton and occlusal function in addition to planning both the predistraction and postdistraction orthodontic care. Based on careful clinical evaluation, dental study models, photographic analysis, cephalometric evaluation, and evaluation of three-dimensional computed tomographic scans, the orthodontist, in collaboration with the surgeon, plans distraction device placement and the predicted vectors of distraction. Both surgeon and orthodontist closely monitor the patient during the active distraction phase, using intermaxillary elastic traction, sometimes combined with guide planes, bite plates, and stabilization arches, to mold the newly formed bone (regenerate) while optimizing the developing occlusion. Postdistraction change caused by relapse is minimal. growth after mandibular distraction is variable and appears to be dependent on the genetic program of the native bone and the surrounding soft tissue matrix. A significant advantage of distraction osteogenesis is the gradual lengthening of the soft tissues and surrounding functional spaces. Distraction osteogenesis can be applied at an earlier age than traditional orthognathic surgery because the technique is relatively simple and bone grafts are not required for augmentation of the hypoplastic craniofacial skeleton. In this new technique, the surgeon and the orthodontist have become collaborators in a process that gradually alters the magnitude and direction of craniofacial growth.- - - - - - - - - - ranking = 0.39855124068306keywords = bite (Clic here for more details about this article) |
10/764. Recurrent meningitis in the pediatric patient--the otolaryngologist's role.OBJECTIVE: To assess the etiology of recurrent meningitis in the pediatric patient. DESIGN: Retrospective case series and literature review. SETTING: Tertiary-care pediatric hospital. patients: Children (< 17-years-old) with recurrent meningitis, treated at texas Children's Hospital (TCH) between 1984 and 1995. RESULTS: A review of 463 cases of bacterial meningitis over an 11 year period revealed six children aged 3 months to 15 years with the diagnosis of recurrent meningitis. The patient's age, number of episodes of meningitis, diagnostic investigations performed and etiologies of recurrent meningitis were recorded. Fifteen episodes of meningitis were identified in these six patients; streptococcus pneumoniae represented the bacteriology in 73% of the cases. Two patients were diagnosed with temporal bone abnormalities, two children with immunological deficiencies and no underlying etiology for the recurrent meningitis was identified in the remaining two patients. In this series, one-third of patients had an otolaryngologic etiology for their recurrent meningitis. These six patients, along with a review of the recent literature, will highlight the need for otolaryngological assessment and the importance of considering immunological investigations when managing recurrent meningitis in the pediatric patient. CONCLUSION: We propose that children with recurrent meningitis of unknown etiology undergo: (1) an audiological evaluation; (2) a CT scan of the temporal bones, skull base and paranasal sinuses; and (3) an immunological evaluation.- - - - - - - - - - ranking = 1keywords = record (Clic here for more details about this article) |
