Teleneurology clinics for polyneuropathy: a pilot study.

INTRODUCTION: Polyneuropathy (PN) is a common condition with significant morbidity. We developed tele-polyneuropathy (tele-PN) clinics to improve access to neurology and increase guideline-concordant PN care. This article describes the mixed-methods evaluation of pilot tele-PN clinics at three community sites within the Greater Los Angeles VA Healthcare System. METHODS: For the first 25 patients (48 scheduled visits), we recorded the duration of the tele-PN visit and exam; the performance on three guideline-concordant care indicators (PN screening labs, opiate reduction, physical therapy for falls); and patient-satisfaction scores. We elicited comments about the tele-PN clinic from patients and the clinical team. We combined descriptive statistics with qualitative themes to determine the feasibility and acceptability of the tele-PN clinics. RESULTS: The average tele-PN encounter and exam times were 28.5 and 9.1 min, respectively. PN screening lab completion increased from 80 to 100%. Opiate freedom improved from 68 to 88%. Physical therapy for patients with recent falls increased from 58 to 100%. The tele-PN clinic was preferred for follow-up over in-person clinics in 86% of cases. Convenience was paramount to the clinic's success, saving an average of 231 min per patient in round-trip travel. The medical team's caring and collaborative spirit received high praise. While the clinic's efficiency was equal or superior to in-person care, the limited treatment options for PN and the small clinical exam space are areas for improvement. CONCLUSION: In this pilot, we were able to efficiently see and examine patients remotely, promote guideline-concordant PN care, and provide a high-satisfaction encounter.

A case of Fragile X-associated tremor/ataxia syndrome (FXTAS).

Fragile X-associated tremor/ataxia syndrome (FXTAS) is a late onset neurodegenerative disorder associated with dysfunction of movement, memory, and the peripheral nervous system. We report an 82 years old male who presented with tremors and difficulty with balance that started at 65 years of age. His motor examination revealed decreased strength in left lower extremity. Tremors were seen in both the upper limbs at rest that worsened with movement. Bilateral lower extremities showed absent vibration and proprioception sensations, absent reflexes and upgoing toes. Electrodiagnostic studies revealed sensory predominant axonal sensory-motor peripheral polyneuropathy. Brain MRI revealed microvascular ischemic changes. The cervical and lumbar MRI showed diffuse degenerative changes. Genetic test for heritable causes of ataxia revealed a premutation in Fragile X gene (84 CGG repeats), confirming the diagnosis of FXTAS. On further genetic testing three out of his four daughters also tested positive for the FMR1 premutation. In appropriate clinical setting, Fragile X-associated tremor/ataxia syndrome (FXTAS) should be considered in every middle aged/elderly patient who presented with slowly progressive ataxia, tremor and peripheral polyneuropathy without any history of cognitive or neurological disabilities in childhood.

Permanent teeth with horizontal root fractures after dental trauma. A retrospective study.

The purpose of the present retrospective study was to evaluate the post-traumatic healing of the pulp and periodontium of 32 permanent teeth with horizontal root fractures. Twenty-nine patients, 8-48 years old, who presented at our department with a root fracture between January 2001 and April 2007, participated in the study. Root-fractured teeth with a loosened or dislocated coronal fragment were repositioned and splinted for 14-49 days (average: 34 days). In cases of severe dislocation of the coronal fragment, prophylactic endodontic treatment was performed. Follow-up examinations were conducted routinely after 1,2,3,6, and 12 months. For this study, follow-up took place for up to 7 years post trauma. Of 32 root-fractured teeth, 29 (91%) survived. 10 teeth (31%) exhibited pulpal healing; 13 teeth (41%) were prophylactically endodontically treated within 2 weeks of injury. At the fracture line, interposition of calcified tissue was evident in 6 teeth (19%), and interposition of granulation tissue was observed in 8 teeth (25%). The prognosis of the root-fractured teeth was good, and one-third of the teeth with root fractures possessed a vital pulp at the final examination.

Comparison of intraoral radiography and limited cone beam computed tomography for the assessment of root-fractured permanent teeth.

AIM: To compare intraoral occlusal (OC) and periapical (PA) radiographs vs. limited cone beam computed tomography (CBCT) in diagnosing root-fractured permanent teeth. MATERIAL AND METHODS: In 38 patients (mean age 24 years, range 8-52 years) with 44 permanent teeth with horizontal root fractures, intraoral radiographs (PA and OC) and limited CBCT were used to evaluate the location (apical, middle, cervical third of the root) and angulation of the fracture line. Furthermore, the conventional radiographs and CBCT images were compared for concordance of fracture location. RESULTS: In the PA and OC radiographs, 28 fractures (63.6%) were located in the middle third of the root, 11 (25.0%) in the apical third and 5 (11.4%) in the cervical third. The PA/OC radiographs and the sagittal CBCT images (facial aspect) yielded the same level of root fracture in 70.5% of cases (31 teeth; 95% CI: 54.1-82.7%). The PA/OC radiographs and sagittal CBCT images (palatal aspect) showed the same level of root fracture in 31.8% of cases. There was a statistically significant association between the angle at which the root fracture line intersected the axis of the tooth and the level of root fracture in the facial aspect of the sagittal CBCT images. CONCLUSIONS: The diagnosis of the location and angulation of root fractures based on limited CBCT imaging differs significantly from diagnostic procedures based on intraoral radiographs (PA/OC) alone. The clinical significance for treatment strategies and for the prognosis of root-fractured teeth has to be addressed in future studies.

[Interradicular course of the inferior alveolar nerve at the mandibular right third molar and monostotic fibrous dysplasia affecting the mandibular left third molar in the same patient. A case report]. / Interradikulärer Verlauf des N. alveo- laris inferior bei 38 und apikale monostotische fibröse Dysplasie bei 48 beim selben Patienten. Ein Fallbericht.

To minimize the risk of intraoperative complications, a comprehensive radiological diagnostic work-up should be a routine procedure in oral surgery. This is especially true concerning possible damage to the inferior alveolar nerve during surgical removal of the third molars. The course and location of the nerve are best assessed when evaluating panoramic view images or cone beam CTs. The following case report demonstrates and discusses the importance of a thorough radiological evaluation before surgery, the problems raised by an interradicular course of the inferior alveolar nerve, and the finding of a monostotic fibrous dyplasia in the same patient.
