BACKGROUND: Utilizing the literature, the results of three different minimally invasive surgery (MIS) anterior cervical percutaneous operations for neck/mild radicular pain and magnetic resonance (MR)-documented "contained" (not extruded/sequestrated) discs were evaluated. Results were compared with patients treated nonsurgically for comparable/greater neurological compromise, and even more severe cervical disc disease. METHODS: There were three MIS percutaneous anterior cervical discectomy procedures...

INTRODUCTION: The incidence of vertical root fracture in endodontically treated teeth increases with patient age. This study evaluated the microstructure, chemical composition, and mechanical properties of radicular dentin as a function of aging. METHODS: Single-rooted teeth were obtained from adult donors ranging from age 15 to older than 80 years. Beams were extracted from the middle third of the root and subjected to 4-point flexure to failure to evaluate strength of dentin in terms of donor age...

Leptomeningeal carcinomatosis is a rare but serious complication of solid tumors such as melanoma, breast and lung cancer, as well as gastrointestinal carcinomas. Its clinical manifestation is highly variable, presenting as radicular pain with or without neurological deficits, as well as with headaches and hallucinatory irritation symptoms. Leptomeningeal carcinomatosis is often misdiagnosed, which delays treatment. Here we report a rare case of a patient with BRAF-mutated microsatellite stable colon carcinoma with lymphatic and skeletal metastases, who developed neurological symptoms one month after the initial diagnosis of malignancy...

Seventy per cent of patients with cancer have evidence of metastases and spinal involvement may occur in up to 50 %. Pain is the most frequent symptom and it occurs in 90 % of the patients. It exist three different type of spinal pain : inflammatory, radicular and mechanical pain. Pain could be related to a neurological compromise and treatment becomes urgent. Steroids are introduced even if surgery is indicated. The Spinal Instability Neoplastic Score is a useful tool in order to determine instability in spinal metastases...

BACKGROUND: Odontogenic Cysts & tumors originate through some aberration from the normal pattern of odontogenesis. Ameloblastoma is one of the most frequent intraosseous odontogenic tumors. However it is no longer appropriate to use the diagnosis of ameloblastoma without specifying the type. Varied-clinical entities of ameloblastoma differ in their biologic behaviour. Odontogenic cysts like dentigerous and radicular cysts are less aggressive in nature than odontogenic tumors. Recently, podoplanin commonly used as a lymphatic endothelial marker in cancers has recently been found to play a possible role in odontogenic tumorigenesis also...

Tarlov (perineural) cysts of the nerve root are common and usually incidental findings during magnetic resonance imaging (MRI) of the lumbosacral spine. There are a few case reports where symptomatic thoracic perineural cysts have been described in the literature. We report a case of a high thoracic nerve root perineural cyst that failed conservative therapy, requiring surgical intervention. Our patient presented with radicular symptoms involving the left hand. Imaging workup revealed a cystic lesion of the left T1 nerve root at the level of the foramen...

INTRODUCTION: Spinal dural arteriovenous fistulae (sdAVF) are rare lesions. Patients typically present with slowly progressive myelopathy that is often mistaken for degenerative cervical or lumbar stenosis. On spinal magnetic resonance imaging (MRI), multisegmental T2 hyperintensities along with associated flow voids are pathognomonic of sdAVF. However, diagnosis can be difficult. Definitive diagnosis and localization is achieved with complete spinal angiography. Treatment options include open surgical ligation, endovascular embolization or multimodality treatment...

PURPOSE: The primitive lateral basilovertebral anastomosis (PLBA) is an embryonic longitudinal anastomotic channel that transiently interconnects the developing branches of the vertebrobasilar system. This study reviews the anatomy of the PLBA and describes several variants associated with its partial persistence. METHODS: Four types of vertebrobasilar anomalies linked to the PLBA are illustrated by 13 angiographic observations. RESULTS: The angiographic appearances of (i) typical and atypical persistent trigeminal artery variants, (ii) common trunks of origin for one, two or three cerebellar arteries, (iii) aberrant origins of the cerebellar arteries, and (iv) vertebrobasilar duplications are described...

INTRODUCTION: Periapical surgery is the last resort in the arsenal of an endodontist to effectively deal with periapical lesions that result from necrosis of the pulp. Bone grafts, growth factors and membranes form an array of regenerative materials that influence the healing outcome of periapical surgery. PRESENTATION OF CASE: The main purpose of the two cases reported here was to assess the potential benefits of a combination of bone graft, platelet-rich fibrin (PRF) and amnion membrane in terms of reduced post-operative discomfort, radiographic evidence of accelerated periapical bone healing and present a novel therapeutic option in the management of large periapical lesions...

A growing body of empirical research has confirmed an association between chronic pain and cognitive dysfunction. The aim of the present study was to determine whether cognitive function is affected in patients with a diagnosis of chronic neuropathic or radicular pain relative to healthy control participants matched by age, gender, and years of education. We also examined the interaction of pain with age in terms of cognitive performance. Some limitations of previous clinical research investigating the effects of chronic pain on cognitive function include differences in the pain and cognitive scale materials used, and the heterogeneity of patient participants, both in terms of their demographics and pathological conditions...
