ABSTRACT

OBJECTIVES: The aim of this study was to document the occurrence of a cavernous haemangioma of the external auditory canal, and to review the literature on this pathology. METHODS: We report the clinical presentation, imaging studies, surgical procedure and histological findings for a cavernous haemangioma of the external auditory canal. RESULTS: This patient represents the fourth reported case of cavernous haemangioma affecting only the external auditory canal. A cavernous haemangioma of the external auditory canal, not affecting the tympanic membrane, was surgically removed, without post-operative complications. CONCLUSIONS: Cavernous haemangioma of the external auditory canal is a rare otological pathology. Computed tomography imaging is important in order to precisely define and localise the site and size of the lesion. Histological examination is necessary for the correct diagnosis of the pathology.

ABSTRACT

Multiple paragangliomas of the head and neck are rare conditions. The incidence of multiple paragangliomas is reported to the approximately 10% of the total patients, but in familial cases it increases up to 35-50%. In the head and neck region, the most common association is represented by bilateral carotid body tumors or by carotid body tumor associated with tympanic-jugular glomus. The presence of three synchronous glomus tumors is really rare, as well as association with vagal glomus and carotid body. In this paper the authors present a patient affected ipsilaterally by a carotid body tumor and vagal paraganglioma, focusing on the diagnostic options offered by imaging techniques (CT and MRI).

ABSTRACT

Paragangliomas múltiples de cabeza y cuello son patologías de escasa presentación. Su frecuencia es de aproximadamente el10 por ciento de la totalidad de pacientes, aunque, en casos familiares, la cifra asciende hasta el 35-50 por ciento. En la cabeza y en el cuello la asociación más común son los tumores del cuerpo carotídeo bilaterales o los tumores del cuerpo carotídeo asociados a glomus tímpano-yugular. La presencia de 3 tumores glómicos sincrónicos es especialmente rara, tanto como la asociación de glomus vagal y cuerpo carotídeo. En este artículo los autores presentan un pacinete afecto ipsilateralmente por un tumor del cuerpo carotídeo y un paraganglioma vagal, concentrando las opciones diagnósticas en las que ofrecen las técnicas de imagen (CT y MRI) (AU)

ABSTRACT

BACKGROUND: Calcium-lowering drugs seem to be able to reduce the recurrences of atrial fibrillation (AF) after cardioversion by preventing electrical remodeling of atrial cells. The aim of our study was to prospectively evaluate the efficacy of short-term verapamil therapy associated with propafenone or amiodarone in reducing recurrences of AF after low energy intracardiac cardioversion. METHODS: Eighty-two patients with chronic AF (mean duration 6.1 months, range 1-96 months) underwent low energy intracardiac cardioversion. Forty-one patients (Group A) were instructed to suspend antiarrhythmic therapy 48 hours before the procedure (only chronic amiodarone was allowed). The subsequent 41 patients (Group B), in addition to previous prescriptions, had to take verapamil (120 mg twice daily) for 3 days before low energy intracardiac cardioversion and for 7 days after cardioversion. A right atrium-coronary sinus or right atrium-left pulmonary artery electrode configuration was indifferently utilized. Propafenone (450-900 mg daily) or amiodarone (200 mg daily) was prescribed to all patients after cardioversion. RESULTS: Sinus rhythm was acutely restored in 80 patients (97.6%): the mean number of shocks delivered was 2.3 (range 1-5); the mean energy required was 10.5 J (range 7.2-19.8 J). No statistically significant differences were found between the right atrium-coronary sinus vs right atrium-left pulmonary artery electrode configuration regarding the energy required and the number of shocks delivered. Group A and Group B showed the same number of AF recurrences at the first month of follow-up. CONCLUSIONS: In our study, short-term verapamil treatment associated with propafenone or amiodarone seems to be useless for the prevention of recurrent AF after low energy intracardiac cardioversion.

ABSTRACT

Echocardiographic demonstration of right ventricular thrombosis is relatively common in pulmonary embolism. There are also reports of right ventricular thrombi in patients affected by right myocardial infarction or dilated cardiomyopathy. In arrhythmogenic right ventricular cardiomyopathy single or multiple aneurysms are often present in the right ventricular free wall. These hypoakinetic areas represent a site for potential development of thrombi especially in advanced disease states. In the literature a single case of a patient affected by arrhythmogenic right ventricular cardiomyopathy with right heart failure and atrial and ventricular thrombi is reported. We report a case of arrhythmogenic right ventricular cardiomyopathy with a right ventricular thrombus located inside a single apical aneurysm in the presence of normal right ventricular systolic function.

ABSTRACT

BACKGROUND: Low energy intracardiac cardioversion has recently been introduced into clinical practice to treat both acute and chronic atrial fibrillation. It has also been suggested that low energy intracardiac cardioversion has a higher efficacy rate in restoring sinus rhythm than conventional external cardioversion. METHODS: A prospective study was started in 41 patients (mean age 64.5 years) with chronic atrial fibrillation (mean duration 6.5 months), in order to obtain more data on low energy intracardiac cardioversion concerning: 1) time required to perform low energy intracardiac cardioversion by single venous femoral approach; 2) acute efficacy; 3) incidence of complications; 4) persistence of sinus rhythm after 1 month. RESULTS: Twenty patients had right atrium-coronary sinus (Group A) and 20 right atrium-left pulmonary artery (Group B) electrode configuration for defibrillation. In 1 patient the configuration was not available. In all patients (100%) sinus rhythm was acutely restored. No statistically significant differences were found between the two groups concerning mean energy and impedance required to obtain cardioversion. With mild sedation the discomfort induced by the electrical shock was minimal or mild. Only 44% of patients were in sinus rhythm 1 month after low energy intracardiac cardioversion, in spite of adequate pharmacological therapy. CONCLUSIONS: Low energy intracardiac cardioversion by single venous femoral approach may be considered a very effective and not time consuming procedure in acutely restoring sinus rhythm, with low complication rate; in addition the procedure was well accepted by all patients.

ABSTRACT

OBJECTIVE: Evaluating patients who have had surgical management of acoustic neuroma has relied heavily on the surgeon's viewpoint for determining success. However, the perspective of the surgeon may be different from that of the patient. Thus, a recent increased interest in terms of quality of life has been documented by the literature on this specific topic essentially through the use of a questionnaire. The objective of this paper was to review this topic in our series of patients operated on for acoustic neuroma to ascertain the personal and social impact that surgery has had on their lifestyle. DESIGN: This retrospective study was devoted to increasing statistics to provide more detailed and valid information during the counselling phase. METHODS: This study was carried out on 82 patients who underwent surgery for acoustic neuroma between 1988 and 1997. Each patient was recalled and assessed for his/her postoperative quality of life. Detailed information was requested on the initial postoperative facial, vestibular, and hearing functions; their evolution; and their social consequence. Finally, at the end of the interview, each patient was invited to give a final comment on his/her opinion regarding the outcomes of surgery and preoperative information. RESULTS: Facial function showed a grade I-III in 85.4% of cases, with postoperative neurovegetative dysfunction (taste and lacrimation) in 43%. Audiologic abnormalities (worsening hearing and tinnitus) were complained of in 90% and 57% of the cases, respectively. Twenty-three percent of the patients had various degrees of gait instability; 6% reported postoperative headache at 1-year follow-up. Social consequence (reduced work ability, vocational change, new education, state pension, etc.) was not influenced by surgery in 80%. CONCLUSIONS: Our experience is in general agreement with previously reported statistics. It is interesting to note that our patients exhibited more disturbances linked to the sensory component of facial nerve. In contrast, dysequilibrium had a less negative influence. These outcomes suggest the importance of thorough preoperative counselling in candidates for surgery for acoustic neuroma in order to motivate them and, at the same time, to reduce their psychological discomfort.

ABSTRACT

Considerable controversy exists concerning the existence of statistically significant relationship between Hashimoto's disease and thyroid cancer, since there is very discordance in the incidence reported in literature, ranging from 0.5% by Crile and Hazard (5) to as high as 22.5% by Hirabayashi and Lindsay (9). Within this context, the authors present a clinical case of a patient who previously underwent lobectomy for a nodular papillary cancer of the thyroid. The histological diagnosis after "totalization" procedure proved to be Hashimoto's thyroiditis on a previous cancer. Starting from this case, an accurate review of the existing literature is carried out and some pathogenetic theories are proposed on the correlation between this two lesions.

ABSTRACT

PURPOSE: Facial nerve monitoring is often used to predict postoperative facial function after acoustic neuroma tumor removal. In this study, three methods of predicting facial nerve function were compared. These methods used various parameters of the evoked electromyographic monitoring. MATERIALS AND METHODS: Thirty-four patients who underwent surgery for acoustic neuroma were retrospectively reviewed. Amplitude of ongoing electromyographic activity, stimulation current thresholds, and the amplitude of evoked response were analyzed. The predictive value of the three methods was compared with actual postoperative facial nerve function. RESULTS: One method predicted the final postoperative facial function in 90% of the patients, one method in 84%, and the final method failed to predict the final VIIth nerve function in patients with current stimulation thresholds greater than 0.05 mA. CONCLUSION: Analysis of prognostic value showed that one of the three studied proved superior in predicting facial nerve function.

ABSTRACT

PURPOSE: Facial nerve monitoring can be used to predict post-operative facial function after skull base surgery. In this study three methods of prediction of facial function were compared. These methods utilize various parameters of the evoked electromyographic monitoring. MATERIAL AND METHODS: Twenty-three patients who underwent surgery for skull base diseases were retrospectively reviewed. Amplitude of ongoing electromyographic activity, stimulation current thresholds and amplitude of evoked response were analysed. The predictive value of the three methods was correlated with post-operative facial nerve function. RESULTS: The method that used only the stimulation thresholds predicted the final post-operative facial function in 86.9 per cent of the patients. The second employed a mathematical ratio which combined the amplitude of evoked response and the stimulation current thresholds and confirmed the prediction of the facial function in 91.3 per cent of the patients. The last method does not consider the stimulation thresholds greater than 0.05 mA and failed to predict the final VIIth nerve function in patients in whom the stimulation was greater than 0.05 mA. CONCLUSION: Analysis of prognostic value demonstrates that the first two methods had the smaller degree of variation showing the better sensitivity.

ABSTRACT

Colour Doppler flow mapping (CD) has proved to be a very sensitive and specific means of diagnosing valvular regurgitation and obtaining a rapid semiquantitative estimation of the severity of regurgitation itself. We tried to compare a semiquantitative evaluation of aortic and mitral regurgitation, without time-consuming calculations of regurgitant jet areas, with the conventional visual semiquantitative angiographic estimation. We have also evaluated in detail the interobserver variability of this type of semiquantitation. Two independent observers (OB) have reviewed CD studies of a selected group of 47 consecutive patients who underwent both cineventriculography and aortography for aortic regurgitation (AR) and/or mitral regurgitation (MR), then graded as mild, moderate or severe. At CD, AR and MR were classified as present or absent and graded as mild, moderate or severe. The following interobserver percentage agreements were noted for AR presence or absence, AR grade, MR presence or absence, MR grade, respectively: 96%, 83%, 96%, 83%. Likewise, the respective echo-angio agreements were 90%, 58%, 80%, 70%. Agreement was significant (P less than 0.001) in all cases. Thus, good interobserver and echo-angio agreement was found in the CD assessment of AR and MR. However, under- or overestimation of CD vs. angio was noted in several cases (mostly by one grade). Underestimation of CD vs. angio was 27% for AR and 18.5% for MR; overestimation of CD vs. angio was 15% for AR and 11.5% for MR. CD has proved to be a useful technique not only for the qualitative but also for the semiquantitative evaluation of aortic and mitral regurgitation, as assessed in the same subjects, with good interobserver agreement.(ABSTRACT TRUNCATED AT 250 WORDS)

ABSTRACT

We report 6 cases of dilated left ventricle with poor left ventricular function and coexisting systemic hypertension in whom left ventricular hypertrophy and normalization of left ventricular function and dimensions have been subsequently documented by M-mode and two-dimensional echocardiographic follow-up studies. Four patients were in New York Heart Association functional Class IV, one in Class III, and one in Class II when first seen. Normalization of left ventricular function and dimensions and features of left ventricular hypertrophy (fractional shortening from 15.0 +/- 5.2 to 39.7 +/- 5.4, left ventricular end-diastolic diameter from 6.6 +/- 0.6 to 4.6 +/- 0.6 cm, left ventricular end-systolic diameter from 5.6 +/- 0.8 to 2.8 +/- 0.6 cm, left ventricular end-diastolic radius/posterior wall thickness from 3.1 +/- 0.5 to 2.0 +/- 0.4, interventricular septum thickness from 1.2 +/- 0.3 to 1.5 +/- 0.3 cm, left atrium from 4.6 +/- 0.6 to 3.5 +/- 0.9 cm) were achieved after adequate medical treatment at the end of the follow-up (11-39 months). It appears from this study that normalization of left ventricular dimensions and function with features of left ventricular hypertrophy can occur after adequate treatment in patients with echocardiographic findings of dilated and poorly contracting left ventricle and coexisting systemic hypertension. It is conceivable, in such cases, to classify the dilatation of the left ventricle as secondary and to suggest the hypothesis of a cause-effect relationship between therapy and normalization of left ventricular parameters with findings of left ventricular hypertrophy. Further studies are needed to clarify this phenomenon.

ABSTRACT

The aim of this study was to evaluate the value and limitations of Cross-sectional Echocardiography (CSE) in the diagnosis of Arrhythmogenic right ventricular dysplasia (ARVD). Diagnosis was based on accepted clinical, electrocardiographic, electrophysiologic and angiographic criteria. CSE criteria for the diagnosis are segmental right ventricular wall motion abnormalities of unknown cause, usually associated with localized or diffuse dilatation of right ventricular (RV) chamber and with the presence of localized anomalies consisting of sacculation or bulging of RV wall. Comparison of CSE and RV angiographic findings was performed in 8 patients with ARVD (6 men and 2 women, aged 10 to 37 years, mean 28 years). CSE and angiography compared closely when diffuse RV enlargement and wall motion abnormalities were identified by both techniques. Bulging and sacculation of the RV wall at CSE predicted the presence of similar lesions at angiography, but agreement for specific location was poor and, in addition, CSE showed low sensitivity in their detection. The inherent different information provided by the two methods added to the subjectivity of the qualitative analysis probably accounts for the inconsistencies. Therefore in patients with diagnosed ARVD RV enlargement, otherwise unexplained, associated with wall motion abnormalities and localized anomalies at CSE strongly supports the diagnosis and avoids the need for angiography. By other hand, in patients with high clinical suspicion of ARVD a negative CSE study can not exclude the diagnosis and angiography should be indicated.

ABSTRACT

The variation in shape, in the global and regional function of the left ventricle (LV) was quantitated by using Two-Dimensional Echocardiography (TDE) in 20 normal subjects (N) (17 males, 3 females, with a mean age of 21.2 years, age range 15 to 34) and compared to 20 patients with aortic regurgitation (AR) (14 males, 6 females with a mean age of 31 years, age range 16 to 51). The left ventricle was subdivided into two TDE short axis cross-sections at the papillary muscle (PM) and at the mitral valve (MV) level. Wall motion was assessed by the following indices; endocardial systolic fractional area change (FAC), wall thickening (Wth) and circumferential fiber shortening (S). The ejection fraction (EF), the diastolic (EID) and systolic eccentricity index (EIS), the end-diastolic volume (EDV), the end systolic volume (ESV) and the LV mass (M) were estimated using a 4 chamber apical view. Measurements of sectional cavity areas, muscle areas and endocardial perimeters were obtained twice independently by two observers using a computer aided system, to achieve the final results as the mean of the 4 measurements. Paired t-test showed a statistically significant variation between PM and MV for FAC in N (p less than 0.001). A statistically significant difference (p less than 0.01) was found for EID between N and AR. The EIS was not significantly different in the two groups. In AR a significant difference was found between EID and EIS (p less than 0.001).(ABSTRACT TRUNCATED AT 250 WORDS)

ABSTRACT

An excessive alcohol intake has been reported as one of the possible causes or risk factors of 'alcoholic cardiomyopathy'. The possibility that this cardiomyopathy may improve or even reverse if the alcohol abuse has been terminated has been suggested, but unequivocal echocardiographic documentation of this improvement has never been described. This study reports the normalization of cardiac chamber dimensions and of variables of left ventricular function documented by M-mode and cross-sectional echocardiographic follow-up studies, after cessation of excessive consumption of alcohol, in three cases of alcoholic cardiomyopathy.

ABSTRACT

The purpose of this study was to define the sequential changes in global and regional right ventricular function, using equilibrium gated radionuclide angiography, following transmural inferior myocardial infarction (IMI) and associated ischemic right ventricular involvement. 24 patients with IMI underwent radionuclide angiography within 72 hours of onset of chest pain; subsequent studies were done at 13 +/- 5 days and at 6 +/- 2 months. Scintigraphic evidence of ischemic right ventricular involvement was defined by depression of right ventricular ejection fraction (less than 40%) and regional wall motion abnormalities (hypo-a-dyskinesia of right ventricular free wall). Significant improvement of global right ventricular ejection fraction was observed in 15 patients at the second study, and in 21 patients at the third study. Right ventricular regional wall motion showed similar improvement from the initial to the final studies. Significant changes in right ventricular function occurred without concurrent changes in global and regional left ventricular ejection fraction. We concluded that patients with IMI and ischemic right ventricular involvement show frequently improvement of global and regional right ventricular function over time. This changes tend to occur early and without significant modifications in left ventricular function. The good prognosis observed in our patients, despite the high incidence of in hospital complications, might be related to the improvement of right ventricular function.
