1/51. Possible manifestation of temporomandibular joint dysfunction on chiropractic cervical X-ray studies.OBJECTIVE: Our purpose was to show that biomechanical alterations toward and away from normal on x-ray studies may be the result of changes in temporomandibular joint dysfunction and to discuss possible neurologic explanations for this phenomenon. CLINICAL FEATURES: Two patients are discussed; the first had migraine headache symptoms, and the second had chronic hypomobility of mandibular opening, dizziness, headache, and neck pain and stiffness. In both patients mensuration changes in different types of cervical x-ray studies were noted in conjunction with exacerbation of, and elimination of, temporomandibular joint dysfunction. INTERVENTION: Comanagement of these cases was done with dental professionals. chiropractic treatment included vectored/linear, upper cervical, high-velocity, low-amplitude chiropractic manipulation of the atlas vertebra, diversified manipulation, myofascial therapy, stretch and spray procedures, and soft tissue manual techniques. CONCLUSION: temporomandibular joint dysfunction may cause cervical muscular and spinal biomechanical changes that may become visible and change on x-ray examination. Further investigation into this phenomenon is recommended.- - - - - - - - - - ranking = 1keywords = soft (Clic here for more details about this article) |
2/51. Atraumatic pneumocephalus: a case report and review of the literature.pneumocephalus or air within the cranial vault is usually associated with disruption of the skull caused by head trauma, neoplasms, or after craniofacial surgical interventions. We report a child who presented with headache and the pathognomonic "succussion splash" and was found to have atraumatic pneumocephalus from forceful valsalva maneuvers. pneumocephalus forms, caused by either a ball-valve mechanism that allows air to enter but not exit the cranial vault, or cerebrospinal fluid (CSF) leaks, which create a negative pressure with subsequent air entry. We review the literature for traumatic and atraumatic causes of pneumocephalus, its complications, and therapy.- - - - - - - - - - ranking = 23.427109575976keywords = neoplasm (Clic here for more details about this article) |
3/51. headache in ehlers-danlos syndrome.OBJECTIVE: ehlers-danlos syndrome (EDS) is a complex hereditary connective tissue disorder with neurologic manifestations that include cerebrovascular disorders and chronic pain. The clinical data collected on 18 patients with EDS and chronic headaches is reported. PROCEDURE: Clinical history, neurologic examination, computerized tomography of the head, magnetic resonance imaging (MRI) of the brain, and electroencephalogram (EEG). Headaches were classified according to the International headache Society and the patients were followed by the author for a minimum of 2 years. FINDINGS: Four patients had migraine with aura, four had migraine without aura, four had tension headaches, four had a combination of migraine and tension headaches, and two had post-traumatic headaches. Nine patients exhibited blepharoclonus but none had history of seizures and their EEGs were normal, ruling out eye closure epilepsy. Although one patient had a small right frontal angioma, a second had Arnold Chiari malformation type I, and a third had an old stroke, headaches did not clinically correlate with their central nervous system (CNS) lesions. CONCLUSION: Chronic recurrent headaches may constitute the neurologic presentation of EDS in the absence of structural, congenital, or acquired CNS lesions that correlate with their symptoms. Individuals with EDS may be prone to migraine due to an inherent disorder of cerebrovascular reactivity or cortical excitability. Additional studies are needed to elucidate the pathogenesis of headaches in EDS.- - - - - - - - - - ranking = 18.609216891047keywords = connective (Clic here for more details about this article) |
4/51. Solitary fibrous tumor of the orbit with a t(9;22)(q31;p13).solitary fibrous tumors are well-described neoplasms found predominantly in the subpleural region but also in many other body sites. They generally behave in a benign fashion, although a few cases that exhibit a malignant course have been reported. Genetic information on solitary fibrous tumors is sparse. This case illustrates a previously unreported finding of a tumor-specific t(9;22)(q31;p13) in a solitary fibrous tumor of the orbit of a 58-year-old man.- - - - - - - - - - ranking = 23.427109575976keywords = neoplasm (Clic here for more details about this article) |
5/51. Proof of the patent subcutaneous fibrous tract in children with V-P shunt malfunction.A connective tissue sheath that forms around the peritoneal catheter of silicone ventriculo-peritoneal (V-P) shunt tubing is quite often observed in children with V-P shunts. However, proof of the passage of cerebrospinal fluid (CSF) through these sheaths has been reported in only one published study to date. We present four cases associated with chronic malfunction of the V-P shunt peritoneal catheter. In these cases, CSF passage through the subcutaneous fibrous tract, which had a pericatheter connective tissue sheath, was demonstrated around the V-P shunt peritoneal catheter. In the first case the patient suffered intermittent headache attacks over a long period of time; abdominal migration of the peritoneal catheter was detected. The second patient, who had been asymptomatic in the follow-up period with an outgrown peritoneal catheter, was admitted with acute hydrocephalus symptoms. A peritoneal catheter disconnection was detected in another patient, who had had multiple shunt revisions previously. In the last case, an obstruction of the peritoneal catheter was detected. The existence of the subcutaneous fibrous tract and its function were demonstrated by radio-opaque shuntogram in two cases and radionuclide shuntogram in the other two cases. In all four cases V-P shunt revision was performed. Within this study, the possible passage of CSF through a fibrous tract in cases of migration, outgrowth, disconnection or obstruction of the peritoneal shunt catheter was demonstrated. In conclusion, patients with shunt malfunction with a well-grown pericatheter fibrous sheath who are either asymptomatic or minimally symptomatic and show no evidence of active ventricular dilatation on their cranial CT scan should not be regarded as having arrested hydrocephalus until radio-opaque or radionuclide shuntogram studies have been done.- - - - - - - - - - ranking = 37.218433782094keywords = connective (Clic here for more details about this article) |
6/51. Dental erosion and aspirin headache powders: a clinical report.The causes of tooth erosion are varied, but all are associated with a chemical attack on the teeth and resulting loss of tooth structure. Etiologic factors related to erosion cited in the literature include bulimia, eating acidic foods, soft drink consumption, acid reflux, and swimming, among others. This clinical report suggests that chronic use of headache powders can also be a factor leading to tooth erosion.- - - - - - - - - - ranking = 1keywords = soft (Clic here for more details about this article) |
7/51. Parietal sinus pericranii: case report and technical note.BACKGROUND: sinus pericranii is a rare vascular anomaly that is defined as a group of abnormal communications between the extracranial and intracranial venous systems, usually involving the superior sagittal sinus. Different surgical techniques have been used to manage this anomaly. Surgical technique and radiologic findings are discussed. CLINICAL PRESENTATION: A case of parietal sinus pericranii is presented that was developed spontaneously. This 33-year-old woman presented with a soft fluctuant mass in the right parietal region adjacent to the midline. She complained of headache and dizziness. The preoperative radiologic findings of simple skull X-ray, computed tomography, bone scan, and direct venogram are presented.The lesion was removed completely and then multiple small vascular channels through the underlying skull were obliterated by air-powered diamond drilling. The presence of vascular endothelium in the pathologic specimen suggested a congenital origin. CONCLUSION: We think this method is very easy and useful for managing the multiple small fenestrations of the sinus pericranii without recurrence.- - - - - - - - - - ranking = 1keywords = soft (Clic here for more details about this article) |
8/51. ophthalmic artery microembolism in giant cell arteritis.A 70-year-old man presented with a history of headache and sudden loss of vision of the left eye. Funduscopic examination showed sector retinal edema and hemorrhage as well as optic disc swelling consistent with anterior ischemic optic neuropathy. The Westergren sedimentation rate was 66 mm/h. Temporal artery biopsy was consistent with giant cell arteritis. Routine transcranial Doppler testing performed on a Pioneer 2020 instrument (Nicolet Vascular, Inc., Golden, CO) equipped with special software for microembolus detection showed a microembolic signal in the left ophthalmic artery. During a subsequent monitoring study, microembolic signals were detected in the anterior and middle cerebral arteries, bilaterally. Microembolism can occur in giant cell arteritis. ophthalmic artery microembolism can be detected in vivo by transcranial Doppler ultrasonography. This new imaging capability can potentially be useful when evaluating patients with vascular disorders of the eye.- - - - - - - - - - ranking = 1keywords = soft (Clic here for more details about this article) |
9/51. Extensive ossification in a craniopharyngioma.A rare extensive ossification occurred in a suprasellar craniopharyngioma of a man who died at 21 years of age. The tumor produced headache, retarded physical and mental development, visual disturbances, and increased intracranial pressure. The neoplasm recurred after surgical and roentgenological treatments. Differentiation of multipotential mesenchymal cells or mesenchymal type cells within the tumor has been suggested as the mode of occurrence of bone in this craniopharyngioma.- - - - - - - - - - ranking = 23.427109575976keywords = neoplasm (Clic here for more details about this article) |
10/51. Meningiomas of the paranasal sinuses.Extracranial meningiomas are rare tumors, comprising approximately 2% of all meningiomas. Previously reported sites include the orbit, parapharyngeal space, and rarely, the paranasal sinuses. A retrospective chart review of patients with meningiomas was performed over the last 25 years, and three patients were identified with meningiomas involving the paranasal sinuses. The locations included the frontal sinus, the ethmoid sinus, and the sphenoid sinus. Presenting symptoms included facial pain and nasal obstruction; two patients noted facial swelling. diagnosis was established via endoscopic transnasal biopsy in two patients. Computed tomographic (CT) guided biopsy was utilized to confirm the diagnosis in the third patient. Surgical extirpation was successfully performed with tumors arising from the ethmoid and frontal sinuses. The patient with neoplasm in the sphenoid sinus underwent radiation therapy. Extracranial meningiomas of the paranasal sinuses are rare tumors that may present a diagnostic and therapeutic challenge. We present three cases and discuss the clinical presentation, radiographic findings, diagnostic evaluation, and treatment options.- - - - - - - - - - ranking = 23.427109575976keywords = neoplasm (Clic here for more details about this article) |
