1/19. MRI of cerebral alveolar echinococcosis.Cerebral alveolar echinococcosis is rare. We report a case with multiple intracranial masses which show cauliflower-like contrast enhancement pattern on MRI. The lesions originated from hepatic involvement with invasion of the inferior vena cava.- - - - - - - - - - ranking = 1keywords = alveolar (Clic here for more details about this article) |
2/19. Numb chin syndrome in Ewing sarcoma.The numb chin syndrome consists of unilateral hypesthesia of the chin and lower lip. In adults, it is often associated with metastatic disease to the mandible, base of the skull, or leptomeninges. In children, it has been associated with infiltration of the inferior alveolar nerve by leukemic cells. We describe two cases of numb chin syndrome in children with Ewing sarcoma. In a child with a solid tumor, this symptom seems to have an ominous meaning and should lead to the investigation of progressive skeletal involvement.- - - - - - - - - - ranking = 0.2keywords = alveolar (Clic here for more details about this article) |
3/19. Lesions of the inferior alveolar nerve arising from endodontic treatment.A lesion of the IAN following endodontic treatment of the lower molars and premolars is not a rare event and presents an uncomfortable situation both for the dental surgeon and the patient. Injury can result on the one hand by direct intrusion of the instrument through the apex into the mandibular canal, and on the other by the filling material which becomes forced into the mandibular canal. In the latter case, a nerve lesion will only result when the filling material contains neurotoxic substances such as paraformaldehyde. With a direct lesion or when forcing of resorbable filling material into the mandibular canal is suspected, one should first employ a wait-and-see approach, because usually the only nerve damage is in the form of neuropraxy or axonotmesis for which there is a high rate of spontaneous regeneration. However, if neurotoxic filling material is introduced into the direct vicinity of the nerves, the mandibular canal should be opened and the filling material should be removed as early as possible. If the filling material is forced directly within the endoneurium between the nerve bundles, the damaged nerve sections must be resected and bridged using transplants from the sural or greater auricular nerves.- - - - - - - - - - ranking = 0.8keywords = alveolar (Clic here for more details about this article) |
4/19. Inferior alveolar nerve paresthesia caused by endodontic pathosis: a case report and review of the literature.Sensory disturbances such as anesthesia, hypoesthesia, hyperesthesia, and paresthesia may be present in the oral cavity, stemming from many local and systemic factors. paresthesia of the inferior alveolar nerve is quite rare because of the unique anatomy of this nerve. Among other effects, periapical lesions can damage the nerve, resulting in paresthesia of its innervated area. Only a few cases of paresthesia caused by these lesions are reported in the literature. In this report we present a case of paresthesia of the right inferior alveolar nerve; discuss the anatomy, pathobiology, and etiology; and suggest that a periapical lesion affecting the lower right second molar (No. 31) may have been the cause. The routine x-rays (intraoral and panorex) and the axial and cross-sectional tomographs of the mandible by means of computed tomography contribute to making this case a good example of nerve injury.- - - - - - - - - - ranking = 1.2keywords = alveolar (Clic here for more details about this article) |
5/19. Complications of an intra-arterial injection from an inferior alveolar nerve block.BACKGROUND: Unintended intravascular injections from inferior alveolar nerve blocks result in frustrating complications, both systemically and locally. It is imperative that the dentist diagnose the complication and treat it appropriately. Sometimes, several reactions occur simultaneously. CASE DESCRIPTION: The authors present a case report that illustrates some of the many complications resulting from inferior alveolar nerve block injections. In this case, complications developed from intra-arterial injection of local anesthetic. The facial skin, intraoral structures and eye were affected. Within 60 minutes of the injection, all structures returned to their normal state. Prompt diagnosis and reassurance usually calm the patient. CLINICAL IMPLICATIONS: Even when clinicians use the utmost care, by aspirating before the injection and noting anatomical landmarks, intra-arterial injections can occur during inferior alveolar nerve blocks. Fortunately, permanent damage to nerves, facial and oral tissues, and eyes is rare. The practitioner should diagnose and treat the problems appropriately to avoid any irreversible complications.- - - - - - - - - - ranking = 1.4keywords = alveolar (Clic here for more details about this article) |
6/19. Necrotizing sialometaplasia: an unusual bilateral presentation associated with antecedent anaesthesia and lack of response to intralesional steroids. Case report and review of the literature.Necrotizing sialometaplasia is a self-limiting, variably ulcerated benign process affecting minor salivary glands. Accurate histological diagnosis is paramount, as it has been mistaken for malignancy, which has resulted in excessively aggressive and unnecessary radical surgery. A unique case of bilateral necrotizing sialometaplasia, presenting with anaesthesia of the greater palatine nerves, is described. An attempt at active therapy with intralesional steroids had no effect on the course of the condition.- - - - - - - - - - ranking = 0.00049405466743948keywords = process (Clic here for more details about this article) |
7/19. Demyelination during anti-tumor necrosis factor alpha therapy with infliximab for Crohn's disease.BACKGROUND: Inflammatory demyelinating disease of the central nervous system may be linked to anti-tumor necrosis factor alpha therapy. CASE history: A 19-year-old female with Crohn's ileocolitis developed right arm and leg numbness and right hand weakness 4 weeks after the initiation of infliximab. neurologic examination confirmed upper and lower right extremity sensory and motor deficits. MRI examination of the head and thoracic cord showed multiple gadolinium-enhancing lesions with distribution and configuration most suggestive of multiple sclerosis or other demyelinating process. The infliximab therapy was immediately stopped and follow-up at 8 weeks revealed symptomatic improvement. CONCLUSION: This case report describes the onset of a demyelinating process after the institution of infliximab therapy in a patient with Crohn's disease.- - - - - - - - - - ranking = 0.00098810933487897keywords = process (Clic here for more details about this article) |
8/19. Inferior alveolar nerve paresthesia relieved by microscopic endodontic treatment.We experienced two cases of inferior alveolar nerve paresthesia caused by root canal medicaments, which were successfully relieved by microscopic endodontic treatment. In the first case, the paresthesia might have been attributable to infiltration of calcium hydroxide into the mandibular canal through the root canals of the mandibular left second molar tooth. In the second case, the paresthesia might have been attributable to infiltration of paraformaldehyde through the root canals of the mandibular right second molar tooth. The paresthesia was relieved in both cases by repetitive microscopic endodontic irrigation using physiological saline solution in combination with oral vitamin B12 and adenosine triphosphate.- - - - - - - - - - ranking = 1keywords = alveolar (Clic here for more details about this article) |
9/19. Successful inferior alveolar nerve decompression for dysesthesia following endodontic treatment: report of 4 cases treated by mandibular sagittal osteotomy.Endodontic overfilling involving the mandibular canal may cause an injury of the inferior alveolar nerve (IAN) resulting in disabling sensory disturbances such as pain, dysesthesia, paresthesia, hypoesthesia, or anesthesia. Two fundamental mechanisms are responsible for the injury: the chemical neurotoxicity and the mechanical compression caused by the extruded material. Although spontaneous resorption has been described for some materials, early surgical exploration with removal of the material and decompression of the IAN should be performed, irrespective of the material used, given that the importance of nerve damage increases with the duration of the injury. We report 4 cases of disabling dysesthesia and paresthesia following endodontic treatment of lower molars in which sagittal osteotomy was used to remove the endodontic paste and to perform nerve decompression. All the patients experienced immediate relief of dysesthesia and paresthesia.- - - - - - - - - - ranking = 1keywords = alveolar (Clic here for more details about this article) |
10/19. Neck-tongue syndrome.OBJECTIVE: To discuss a case of neck-tongue syndrome (NTS) affecting a dancer/figure skater, review literature summarizing the pathogenesis and treatment, and offer new categorization of neck-tongue syndrome. CLINICAL FEATURES: A 24-year-old female dancer/skater sought treatment for recurrent episodes of right-sided upper neck pain with associated ipsilateral numbness of her tongue following brisk active rotation. Radiographs revealed a narrowing of the left para-odontoid space. physical examination revealed a mildly painful restriction in rotation at C1-2 with no apparent muscular hypertonicity. INTERVENTION AND OUTCOME: The patient had sought chiropractic treatment for this condition several times since she was 8 years old. Diversified chiropractic adjustments were applied to restrictions throughout the cervical spine as determined by the clinician. No other interventions were employed. The patient experienced significant improvement in frequency and intensity of the neck and tongue symptoms following spinal manipulative therapy applied to her cervical spine. CONCLUSIONS: There are 2 categories of NTS: complicated NTS due to the presence of an underlying disease process (inflammatory or degenerative) and uncomplicated NTS (idiopathic or trauma-related). This case report is of uncomplicated NTS that responded favorably to spinal manipulative therapy directed at the cervical spine. In the absence of upper cervical instability, spinal manipulative therapy appears to be beneficial and should be considered in all cases of uncomplicated NTS.- - - - - - - - - - ranking = 0.00049405466743948keywords = process (Clic here for more details about this article) |
