The aim of the study was assessment of clinical efficacy and safety of terazosine (setegis) in patients with benign prostatic hyperplasia (BPH) and concomitant cardiovascular disease. A total of 62 BPH patients with cardiovascular disease (ischemic heart disease, hypertension) having indications for alpha-adrenoblockers (mean age 74 +/- 11 years, 58-85) received terazosine in a dose 1-5 mg for 2 months. Clinical efficacy of terazosine was assessed by IPSS scale, residual urine, maximal voiding velocity. Safety of the drug was controlled by monitoring of arterial pressure, ECG, echo-CG. All the tests were made before therapy, on the treatment week 2, 4 and 8. The response was 90.3%. Overall symptoms score decreased by 37.0%, quality of life score rose by 23.8%. Amount of residual urine fell by 64.8%, maximal voiding velocity increased by 36.6%. Moderate effects of the drug (vertigo, weakness) occurred in 11.3% patients for 1 or 2 days after start of the therapy and were due to a moderate fall of arterial pressure in normotensive patients. Later artertial pressure stabilized, ECG registered no exacerbations of ischemic heart disease, no anginal attacks, no change in cardiac rhythm. Thus, terazosine (setegis) is effective and safe in BPH patients with cardiovascular disease. Pretreatment consultation of the cardiologist is desirable for correction of basic antianginal therapy.

Sudden deafness without associated neurological signs and symptoms is typically attributed to a viral inflammation of the labyrinth. Sudden deafness as a heralding manifestation of basilar occlusion has rarely been described. A 60-year-old male with hypertension presented with an acute onset of isolated sudden deafness with vertigo. On admission, initial brain MRI, including diffusion-weighted images, was normal. Two days after the onset of symptoms, the patient presented with an exacerbation of vertigo. A follow-up MRI scan revealed new infarcts involving the right middle cerebellar peduncle, right dorsolateral pons and right anterior cerebellum. In this patient, the acute onset of isolated sudden deafness with vertigo may have been a heralding manifestation of the pontocerebellar infarction.

Investigation of vestibular system using a standard method of electro-nystagmography in complex otoneurologic examination does not provide enough information on the etiology of vestibular analyzer lesion, location and diffusion of the pathological process. Neurovisual methods, in particular MRI and CT, have demonstrated high diagnostic validity in such pathological states as tumors of pons cerebellum and posterior focca; infarctions in the stem and cerebellum regions. The study revealed a role of MRI and CT in etiology of vertigo and lesions of cochleovestibular analyzer. One hundred thirty patients aged 28-74 years with recurrent attacks of systemic rotary vertigo and other its appearances have been examined. In 14 (11%) patients such an attack was accompanied by loss of consciousness, falls, double-vision and other neurological symptoms. All the patients underwent otoneurological examination, computer electronystagmography, auditory evoked potentials registration, CT and MRI. It is shown that peripheral cochleovestibular syndromes caused by arterial hypertension, atherosclerosis and autonomic vascular dystonia are rarely characterized by focal cerebral changes (11 patients by CT data and 17 by MRI).

Asymptomatic non neoplastic cysts of the pineal region are common incidental findings in adults. On the contrary, voluminous and symptomatic cysts of the pineal region are rare and their management are not well defined. We present the case of a 32-year-old woman suffering who suffered from mild intracranial hypertension, gait disturbance and vertigo for one year. The neuroradiological workup showed a voluminous cyst of the pineal region responsible for an obstructive hydrocephalus. An endoscopic etiological treatment was decided. The operation consisted in a marsupialization of the cyst in the third ventricle with a stereotactic guidance system. A frozen section of the cyst wall failed to show tumoral cells. Immediate postoperative course was uneventful. Intracranial hypertension symptoms resolved in 24 hours. Clinical examination and neuropsychological testing were normal at two years postoperatively. The two years follow-up cerebral MRI demonstrated a remnant cystic cavity without mass effect and the patency of the aqueduct of Sylvius. Endoscopic treatment of symptomatic pineal cysts constitutes an interesting therapeutic alternative in the management of this pathology.

Roentgen computed tomography (RCT) and MR-imaging (MRI) were used in investigation of vertigo etiology and affection of the cochleovestibular analyzer in 130 patients aged 28 to 74 years with recurrent systemic rotatory vertigo or its other symptoms. All the patients have undergone comprehensive otoneurological examination, RCT and MRI which showed that peripheral cochleovestibular syndromes (PCVS) caused by arterial hypertension (AH), atherosclerosis (AS), vascular dystonia (VD) are rarely characterized by focal alterations in the brain. PCVS comparison with blood flow in the vertebral arteries (VA) detected most frequently anomalies and asymmetries of the diameters. MR-angiography plays an important role in verification of pathology of intracranial VA. In central cochleovestibular syndrome (CCVS) with AH, AS, VD, principal pathological changes were registered in the brain trunk and cerebellum by MRI. Vestibulometry and otoneurological method detect not only vascular cochleovestibular peripheral and central syndromes but also to make differential diagnosis. RCT and MRI verify cochleovestibular syndromes in patients with multiple encephalomyelitis, VIII nerve neurinoma and tumors of the posterior cranial fossa.

To assess the frequency and clinical characteristics of meningocele and meningoencephalocele into the middle ear, at an otological referral center of Mexico city. After analyzing 586 recordings of middle ear surgery, we identified that 3 (0.5%) had defects of the tegmen timpani, 2 had brain abscesses (0.34%) and 1 had (0.17%) a facial palsy. Two of the patients with defects of the tegmen timpani had herniation of the intracraneal tissue. Case 1. A 38 year old woman with a history of bilateral chronic otitis media, with 2 surgeries in the left ear. She was seeking medical care because of right hearing loss. However, computed tomography and magnetic resonance showed a defect of the tegmen timpani with temporal lobe herniation in the left ear. Case 2 was a 46 year old woman with no history of ear disease, just high blood pressure. She was seeking medical care because of right hearing loss, vertigo and headache. The clinical evaluation suggested tissue in the middle ear and the computed tomography showed a defect of the tegmen timpani, meningocele was confirmed by surgery. In the 2 patients the clinical characteristics did not suggest herniation of intracraneal tissue as the first diagnosis. This show us the importance of an intended evaluation and image studies to make an early diagnosis.

We studied characteristics of vestibular and acoustic disorders in patients with arterial hypertension, atherosclerosis and vascular dystonia; correlation between peripheral cochleovestibular syndromes (PCVS) and circulation in the major and intracranial arteries, central hemodynamics, organic changes in the brain. We discovered that anomalies and asymmetry in vertebral arteries diameters, stenoses, reduced stroke and minute blood volumes play an essential role in development of PCVS. The latter are rarely accompanied with ischemic foci in the brain. Medication of vascular vertigo consists in administration of an adequate drug. We believe that betaserk is most effective.

This report is about a rare case of a lumbar spinal dural arteriovenous fistula (DAVF) with distant brainstem symptoms of vertigo and ataxia. Brain magnetic resonance imaging (MRI) demonstrated a high signal abnormality in the lower pons, medulla, and cervico-medullary junction, presumably related to venous hypertension. Spinal MRI revealed markedly dilated veins along the dorsal aspect of the cord, while spinal angiography confirmed the presence of a lumbar spinal DAVF. Because lumbar DAVF may cause remote brainstem symptoms, spinal DAVF should be considered in the differential diagnosis of high signal MRI abnormalities localized in the brainstem. Properly extending the scanning range is essential in the diagnosis.

We investigated distortion product otoacoustic emissions (DPOAE) as a prognostic factor in idiopathic sudden sensorineural hearing loss (ISSHL) patients with the time-dependent Cox proportional-hazards model. We also compared the importance of the prognostic factors that are reported in the literature. 108 patients with ISSHL were included. Both DPOAE and pure tone audiometry were performed everyday for a maximum of 7 days during admission and followed every other week or monthly after discharge. All DPOAE amplitudes were analyzed at 2f1-f2--namely 1093, 1375, 1750, 2187, 2781, 3500, 4375, and 5500 Hz. The average of two series of DPOAE intensity corrected for the noise level in eight frequencies was coded as dichotomous at > or =6 or <6 dB. We selected the most updated DPOAE at 3 days or more before the assessment of recovery into the analysis. The potential confounders including age, sex, history of vertigo at onset, history of hypertension, diabetes, coronary arterial disease, and stroke, configuration and severity of initial pure tone audiometry, the duration from onset to treatment, auditory brainstem response (ABR), vestibular evoked myogenic potential (VEMP), and plasma triglyceride and cholesterol levels, hemoglobin level, and erythrocyte sedimentation rate were collected for evaluation. The results showed that a better DPOAE amplitude was a significantly good prognostic indicator both in univariate analysis (recovery rate ratio = 3.626, 95% CI = 2.119-6.205, p < 0.0001) and multivariate analysis (recovery rate ratio = 2.94, 95% CI = 1.537-5.624, p = 0.0011). The Kaplan-Meier estimates showed that the younger age group (< or =40 years) with better initial pure tone audiometry (<65 dB) represented a better prognosis that was compatible with previous literature (log-rank test, p = 0.0297 and p = 0.0019 respectively). In the univariate analysis, normal ABR and VEMP waveforms were associated with a better prognosis (ABR: recovery rate ratio = 2.984, 95% CI = 1.742-5.112, p < 0.0001; VEMP: recovery rate ratio = 1.978, 95% CI = 1.183-3.305, p = 0.0093). The configuration of initial audiometry was also a significant prognostic factor that patients with scale-out type (recovery rate ratio = 0.228, 95% CI = 0.089-0.584, p = 0.002) and tent type (recovery rate ratio = 0.081, 95% CI = 0.008-0.778, p = 0.0295) were associated with a poorer prognosis than those with the flat type in the multivariate analysis. In this study, the time-dependent Cox proportional-hazards model established the prognostic value of DPOAE for ISSHL patients. This model can also be used for comparison of different treatment protocols. In addition, the further development of a predictive model based on this method is worthy of being investigated.

Megadolichobasilar anomaly, a dilatant arteriopathy of the basilar artery attributable to chronic arterial hypertension, can cause cranial nerve compression syndromes of the cerebellopontine angle or infarcts of the vertebrobasilar circulation. In this paper, we report on a patient with known megadolichobasilar anomaly and a partially thrombosed fusiform aneurysm of the basilar artery, who presented with acute-onset vertigo and subsequent deafness due to thromboembolic occlusion of the labyrinthine artery. Because of the vascular origin of the patient's symptoms, his vertigo disappeared over time while the deafness persisted.
