In proportion to a rapid increase of dialysis patient, death caused by neurological complications is increasing annually among long-term hemodialyzed patients. A case of chronic subdural hematoma during long-term hemodialysis is presented. A 35-year-old male had undergone hemodialysis three times weekly for four years. He had marked changes in body-weight and blood pressure between hemodialysis. In March 1983, he had a headache, vomiting, and left hemiparesis. The CT scan showed a right subdural hematoma. He was admitted to our hospital 10 days later because of progressive hemiparesis and speech disturbance. The neurological examination showed left hemiparesis with sensory deficit and dysarthria. The CT scan showed an increase in the size of the subdural hematoma. Bleeding time was over 10 minutes. A right-sided burr hole was made and altered blood was removed and irrigated. After operation, headache and weakness rapidly subsided, but the next morning, attacks of convulsion occurred. The CT scan showed the rebleeding in the subdural space. After correcting the level of serum potassium by hemodialysis, a right parietal craniotomy was performed. Hematoma of about 100 g was removed and the capsule of the hematoma showed organized tissue histologically. Postoperatively, although attacks of convulsion occurred temporarily, he gradually improved. The levels of serum potassium and BUN were controlled by several treatments of hemodialysis. He was discharged with only mild hemiparesis. Subdural hematoma caused by hemodialysis is a very important complication. Chronic subdural hematoma is sometimes very difficult to differentiate from dysequilibrium syndrome or dialysis dementia. The CT scan is a very valuable examination to rule out subdural hematoma.

Based on Benabid's experimental and clinical findings that low-frequency (50 Hz) electrical stimulation of the ventral intermediate thalamic nucleus may increase tremor, while higher frequencies (> 100 Hz) lead to suppression of the tremor, we implanted a stimulation electrode in 33 thalami among 27 patients. Six patients were implanted bilaterally. 23 suffered from Parkinson's disease, 4 from essential tremor. All patients had a drug-resistant tremor. The Vim target was calculated based on stereotactic ventriculography. An intra-operative neurophysiological target control was performed on all patients. After a monopolar (12 thalami) or quadripolar (21 thalami) lead was implanted we then connected it to a percutaneous extension lead. In the days following the surgery a test stimulation was performed. In all but one patient stimulation resulted in a suppression of the tremor. In a second procedure, a pulse generator (ITREL II; MEDTRONIC) was implanted and connected subcutaneously to the thalamic lead. After implantation of the pulse generator all patients stimulate chronically while some turn off the stimulator at night. In 21 thalami total suppression of tremor was observed, 6 showed major improvement, 4 only minor improvement. There was no significant effect on any other existing symptom of Parkinson's disease. Due to the proximity of Vim to the sensory thalamus the majority of the patients (27 thalami) report slight temporary paraesthesias when the pulse generator is turned on. Two report permanent paraesthesias when stimulation is on. In 4 cases a slight dysarthria occurs under stimulation. In 2 the dysarthria is marked. In one case dysequilibrium occurs under stimulation. All these side effects are reversible when stimulation is turned off. In 3 patients, the lead was displaced due to an insufficient lead fixation, thus making a second procedure necessary to correct the electrode position. We had one complication due to bleeding at the burr hole side. Follow-up ranges from 3 to 48 months. So far in no cases has the effect of stimulation worn off. In conclusion we regard Vim neurostimulation as an effective and safe alternative to conventional thalamotomy and recommend that it should be considered in cases in which drug therapy has failed to affect Parkinsonian or essential tremor. Moreover, we believe that this procedure is a less invasive and equally efficient alternative to classic thalamotomy and thus should be given preference.

Friedreich ataxia is an autosomal recessive neurodegenerative disorder characterized by ataxia of all four limbs, dysarthria, and arreflexia. A variety of measures are currently used to quantify disease progression, including the Friedreich Ataxia Rating Scale, examiner-rated functional disability scales, self-reported activities of daily living and performance measures such as the timed 25-foot walk, 9-hole pegboard test, PATA speech test, and low-contrast letter acuity vision charts. This study examines the rate of disease progression over one and two years in a cohort of 236 Friedreich ataxia patients using these scales and performance measure composites. The Friedreich Ataxia Rating Scale and performance-measure composites captured disease progression, with a greater sensitivity to change over 2 years than over 1 year. The measures differed in their sensitivity to change and in possible bias. These results help to establish norms for progression in FRDA that can be useful in measuring the long-term success of therapeutic agents and defining sample-size calculations for double-blind clinical trials.

Remote cerebellar hemorrhage is a usual complication after supratentorial craniotomy. Especially, only several cases have been reported regarding the occurrence of remote cerebellar hemorrhage after burr hole drainage for the treatment of chronic subdural hematoma (CSDH). In this paper, we present an elder patient with this rare postoperative complication. A 73-year-old man presented with dysarthria and right hemiparesis. Computed tomography (CT) demonstrated a left chronic subdural hematoma. Hematoma drainage through a single burr hole was perfomed. About 3 hours after the surgery, the patient became restless and presented nausea and dizziness with a relatively large amount of drainage of hematoma. CT revealed resolution of the subdural hematoma and bilateral cerebellar hemorrhage appearing as "zebra sign". Magnetic resonance angiography and 3D-CT angiography showed the normal structure of posterior circulation in both the arterial and venous phases. The remote cerebellar hemorrhage was suspected to have happened as a result of overdrainage of hematoma. Finally, he was discharged without any neurological deficits. Although remote cerebellar hemorrhage after drainage through a burr hole for the treatment of chronic subdural hematoma is a rare complication, it is necessary to be aware of the possibility of such a complication after supratentorial surgery.

A 35-year-old patient was brought to the emergency department referring dysarthria, left ear tinnitus for 5 min, and short-lasting blindness, with headache in the 45 min before the clinical presentation. In the magnetic resonance imaging, an acute-subacute lesion in the cerebellum right-anterior lobe (in the territory of the cerebellum anterior artery) and a dilatation near the ostium of the right vertebral artery were seen. For a better assessment, an Angio-CT was done, showing a 9-mm saccular pseudoaneurysm of the right vertebral artery close to the origin of the vessel, without being able to determine if it had been caused because of a dissection. The rest of the study (cerebral vessels and supra-aortic vessels) showed no disorders. He was operated under local anesthesia and sedation a week after the onset of the symptoms. Through a 0.014 wire, a Biotronik PK Papyrus balloon-expandable covered cobalt-chromium stent was deployed covering the hole in the artery. Antiplatelet drugs were prescribed, and the patient was discharged 24 hr after surgery. He has remained symptom free since then.

A 70-year-old man presented to our hospital because of difficulty with discrete movement of the right upper limb and dysarthria. Computed tomography(CT)of the head revealed a chronic subdural hematoma(CSDH)on the left side. The patient underwent single burr-hole irrigation and drainage on the same day. In addition to the burr hole, a cross-shaped dural incision was made which revealed a thick outer membrane and solidified hematoma. We removed as much of the clotted hematoma as possible using a curved suction tube under neuroendoscopy. The postoperative CT revealed that the hematoma was partially removed and the mass effect was reduced. As a result, the patient's neurological deficits improved. We reached a diagnosis of organizing CSDH following histologic examination of the removed hematoma that showed inflammatory cell infiltration and multiplication of fibroblasts. Neuroendoscopic hematoma evacuation via a burr hole is minimally invasive and may be a useful procedure in the treatment of some cases of organizing CSDH.

Chronic subdural hematoma (CSDH) can be easily treated by burr hole surgery. However, several complications including intracerebral hemorrhage (ICH), subarachnoid hemorrhage (SAH), and acute subdural hematoma are rare after evacuation of a CSDH. A 77-year-old man was admitted with right hemiparesis and dysarthria. A brain computed tomography (CT) scan revealed a bilateral CSDH with midline shifting toward the right side. The patient got the burr hole trephination with the catheters insertion in the both sides of parietal area under the local anesthesia. After burr hole surgery immediately, he developed left side weakness and decreased level of consciousness. Repeat CT scans detected a diffuse SAH and multiple small ICHs. He was treated conservatively and fully recovered at discharge after 1 month. To avoid these complications, slow and gradual drainage of the CSDH is needed. The authors report a rare case of SAH and multipunctate ICHs in both cerebral hemispheres after evacuation of a bilateral CSDH.

Macroglossia is a rare clinical condition defined as an enlarged tongue. Macroglossia can cause structural deformities like diastema and disproportionate mandibular growth and present functional disorders such as dysarthria, dysphonia, and respiratory problems. A 7-year-old boy who had lymphangiomatous macroglossia was treated with a reduction glossectomy by anchor-shaped combination of a U-shape and modified key-hole resection. Postoperatively, the reduced tongue was contained completely within the oral cavity, but open bite remained due to prognathism. Sensory and motor nerves to the tongue appeared to be intact, and circulation was adequate. This patient will be monitored for recurrence of tongue enlargement.
