    Benign paroxysmal positional vertigo is a common cause of disabling vertigo with a high rate of recurrence. Although connections between vitamin D deficiency and osteoporosis, as well as between osteoporosis and benign paroxysmal positional vertigo have been suggested respectively in the literature, we are not aware of any publication linking vitamin D and benign paroxysmal positional vertigo. As a hypothesis, we suggest that there is a relation between insufficient vitamin D level and benign...

    Benign paroxysmal positional vertigo is one of the most common types of vertigo caused by peripheral vestibular dysfunction. Although head trauma, migraine, long-term bed rest, Ménière disease, viral labyrinthitis, and upper respiratory tract infections are believed to be predisposing factors, most cases of benign paroxysmal positional vertigo are idiopathic. Ear surgery is another cause, but after non-otologic surgery, attacks of benign paroxysmal positional vertigo are rare. We describe thr...

    Benign paroxysmal positional vertigo (BPPV) is probably the most common diagnosis at vertigo clinics. Seasonal cycles of several human illnesses could be attributed variously to changes in atmospheric or weather conditions. In this retrospective study, patients with BPPV from January 2010 to December 2012 were studied, and their charts were reviewed. Statistical analysis revealed a statistically significant difference in patients' numbers among different months of the year. Also there is a significant statistical correlation between the numbers of patients with climatic variations especially the temperature. The present paper discusses the possible explanations for these results which confirms the seasonal variations in BPPV, together with a review of literature to view the possible associations with other disorders that causes such sea-sonality.

    Full Text Available Benign paroxysmal positional vertigo is the cause of peripheral vertigo, which only takes seconds posed by certain head and body position and led to severe attacks of vertigo. Therefore, it is a disturbance that causes a continuous fear of fall and anxiety in some patients. Although benign paroxysmal positional vertigo is the most common cause of peripheral vertigo, it may cause unnecessary tests, treatment costs and the loss of labor due to the result of the delay in the diagnosis and treatment stages. Diagnosis and treatment of this disease is easy. High success rates can be achieved with appropriate repositioning maneuvers after taking a detailed medical history and accurate assessment of accompanying nystagmus. The aim of this paper was to review the updated information about benign paroxysmal positional vertigo. [Archives Medical Review Journal 2015; 24(4.000: 555-564

    Full Text Available Normal 0 false false false EN-US X-NONE X-NONE MicrosoftInternetExplorer4 Benign Paroxysmal Positional Vertigo (BPPV is one of the most frequent Neurotology disorders. Benign Paroxysmal Positional Vertigo is a vestibular disorder in which 17% -20% of patients complained of vertigo. In the general population the prevalence of BPPV is between 11 to 64 per 100,000 (prevalence 2.4%. Benign Paroxysmal Positional Vertigo is a disturbance in the inner ear with positional vertigo symptoms that occur repeatedly with the typical nystagmus paroxysmal. The disorders can be caused either by canalithiasis or cupulolithiasis and could in theory be about three semicircular canals, although superior canal (anterior is very rare. The most common is the form of the posterior canal, followed by a lateral. The diagnosis of BPPV can be enforced based on history and physical examination, including some tests such as Dix-Hallpike test, caloric test, and Supine Roll test. The diagnosis of BPPV is also classified according to the types of channels. Management of BPPV include non-pharmacological, pharmacological and operations. Treatment is often used non-pharmacological includes several maneuvers such as Epley maneuver, Semount maneuver, Lempert maneuver, forced prolonged position and Brandt-Daroff exercises. /* Style Definitions */ table.MsoNormalTable {mso-style-name:"Table Normal"; mso-tstyle-rowband-size:0; mso-tstyle-colband-size:0; mso-style-noshow:yes; mso-style-priority:99; mso-style-qformat:yes; mso-style-parent:""; mso-padding-alt:0in 5.4pt 0in 5.4pt; mso-para-margin:0in; mso-para-margin-bottom:.0001pt; mso-pagination:widow-orphan; font-size:11.0pt; font-family:"Calibri","sans-serif"; mso-ascii-font-family:Calibri; mso-ascii-theme-font:minor-latin; mso-fareast-font-family:"Times New Roman"; mso-fareast-theme-font:minor-fareast; mso-hansi-font-family:Calibri; mso-hansi-theme-font:minor-latin; mso-bidi-font-family:"Times New Roman"; mso-bidi-theme-font:minor-bidi;}

    Benign paroxysmal positional vertigo (BPPV) is an unfamiliar and rare complication occurring following osteotome sinus floor elevation (OSFE) and simultaneous implant placement. Etiology of this disorder is commonly displacement of otoliths by vibratory forces transmitted by osteotomes and mallet along with the hyperextension of the head during the operation, causing them to float around in the endolymph. This report presents a case of protracted BPPV following OSFE and simultaneous implant placement. A 43-year-old female suffered intense vertigo and nausea immediately after implant placement using an OSFE procedure. Upon further questioning after the procedure she gave an account of two times vertigo history within the last 9 years. Despite nootropic drug medication and canalith repositioning procedure applied by a specialist at operation night, the condition did not improve. Patient did not totally recover and was admitted again after 1 month. After repeated maneuvers, nine dosage intravenous serous fluid and piracetam administration the patient recovered. Duration of these procedures took 10 days and the patient was successfully treated with no recurrence of dizziness. Prevention and management of OSFE related BPPV are reviewed especially in patients having prior vertigo history in this report. PMID:27408469

    In our daily life, small flows in the semicircular canals (SCCs) of the inner ear displace a sensory structure called the cupula which mediates the transduction of head angular velocities to afferent signals. We consider a dysfunction of the SCCs known as canalithiasis. Under this condition, small debris particles disturb the flow in the SCCs and can cause benign paroxysmal positional vertigo (BPPV), arguably the most common form of vertigo in humans. The diagnosis of BPPV is mainly based on the analysis of typical eye movements (positional nystagmus) following provocative head maneuvers that are known to lead to vertigo in BPPV patients. These eye movements are triggered by the vestibulo-ocular reflex, and their velocity provides an indirect measurement of the cupula displacement. An attenuation of the vertigo and the nystagmus is often observed when the provocative maneuver is repeated. This attenuation is known as BPPV fatigue. It was not quantitatively described so far, and the mechanisms causing it remain unknown. We quantify fatigue by eye velocity measurements and propose a fluid dynamic interpretation of our results based on a computational model for the fluid-particle dynamics of a SCC with canalithiasis. Our model suggests that the particles may not go back to their initial position after a first head maneuver such that a second head maneuver leads to different particle trajectories causing smaller cupula displacements.

    Full Text Available Benign paroxysmal positional vertigo (BPPV, the most frequent cause of vertigo is associated with high morbidity in the elderly population. The most common form is linked to debris in the posterior semicircular canal. However, there has been an increasing number of reported BPPV cases involving the horizontal canals. The purpose of this article is to highlight the clinical features, diagnosis, and treatment in 37 patients with horizontal canal BPPV; twenty-six with geotropic nystagmus, and eleven with the apogeotropic form. Treatment consisted of the Gufoni manoeuver in eighteen patients (48.6%, the barbecue 360° maneuver in twelve patients (32.4%, both manoeuvers in four patients (10.8%, both manoeuvers plus head shaking in one patient (2.7%, and the Gufoni maneuver plus head shaking in two patients. Cupulolithiasis patients were asked to sleep in a forced prolonged position. We obtained a complete resolution of vertigo and nystagmus in 30 patients (81.0% on the initial visit.

    2013-04-01

    Full Text Available Introduction: Benign Paroxysmal Positional Vertigo (BPPV is a very common vestibular disorder characterized by brief but intense attacks of rotatory vertigo triggered by simple rapid movement of the head. The integrity of the vestibular pathways can be assessed using tests such as digital vectoelectronystagmography (VENG and vestibular evoked myogenic potentials (VEMP. Aim: This study aimed to determine the VEMP findings with respect to latency, amplitude, and waveform peak to peak and the results of the oculomotor and vestibular components of VENG in patients with BPPV. Method: Although this otoneurological condition is quite common, little is known of the associated VEMP and VENG changes, making it important to research and describe these results. Results: We examined the records of 4438 patients and selected 35 charts after applying the inclusion and exclusion criteria. Of these, 26 patients were women and 9 men. The average age at diagnosis was 52.7 years, and the most prevalent physiological cause, accounting for 97.3% of cases, was ductolithiasis. There was a statistically significant association between normal hearing and mild contralateral sensorineural hearing loss. The results of the oculomotor tests were within the normal reference ranges for all subjects. Patients with BPPV exhibited symmetrical function of the semicircular canals in their synergistic pairs (p < 0.001. The caloric test showed statistically normal responses from the lateral canals. The waveforms of all patients were adequate, but the VEMP results for the data-crossing maneuver with positive positioning showed a trend toward a relationship for the left ear Lp13. There was also a trend towards an association between normal reflexes in the caloric test and the inter-peak VEMP of the left ear. It can be concluded that although there are some differences between the average levels of the VENG and VEMP results, these differences were not statistically significant

    Objective:To investigate the efficacy of quick repositioning maneuver for horizontal semicircular canal benign paroxysmal positional vertigo (H-BPPV). Methods:Clinical data of 67 patients with H-BPPV who underwent quick repositioning maneuver in our hospital from July 2009 to November 2014 were retrospectively analyzed. The maneuver involved rotating the patient in the axial plane for 180? from the involved side towards contralateral side as quickly as possible. Results:Complete symptom resolution was achieved in 61 patients (91.0%) at one week and in 64 patients (95.5%) at 3 months post-treatment. During the repositioning maneuver process, there were no obvious untoward responses except transient nausea with or without vomiting in a few patients. Conclusion:The results indicate that the quick repositioning maneuver is an easy and effective alternative treatment in the management of H-BPPV. Copyright © 2015 The Authors.

    We develop the image based computer assisted diagnosis system for benign paroxysmal positional vertigo (BPPV) that consists of the balance control system simulator, the 3D eye movement simulator, and the extraction method of nystagmus response directly from an eye movement image sequence. In the system, the causes and conditions of BPPV are estimated by searching the database for record matching with the nystagmus response for the observed eye image sequence of the patient with BPPV. The database includes the nystagmus responses for simulated eye movement sequences. The eye movement velocity is obtained by using the balance control system simulator that allows us to simulate BPPV under various conditions such as canalithiasis, cupulolithiasis, number of otoconia, otoconium size, and so on. Then the eye movement image sequence is displayed on the CRT by the 3D eye movement simulator. The nystagmus responses are extracted from the image sequence by the proposed method and are stored in the database. In order to enhance the diagnosis accuracy, the nystagmus response for a newly simulated sequence is matched with that for the observed sequence. From the matched simulation conditions, the causes and conditions of BPPV are estimated. We apply our image based computer assisted diagnosis system to two real eye movement image sequences for patients with BPPV to show its validity.

    Background: Benign paroxysmal positional vertigo (BPPV) is linked to vitamin D deficiency. This clinical trial aimed to determine the influence of vitamin D supplementation on intensity of BPPV. Methods: The study population was selected consecutively and the diagnosis of BPPV was made by history and clinical examination and exclusion of other conditions. Intensity of BPVV was assessed based on VAS score (0-10). Serum 25-hydroxyvitamin D (25-OHD) was measured using ELISA method and levels < 20 ng/ml was considered a deficiency. All patients received rehabilitation treatment using Epley's maneuver one time per week for one month. Serum 25-OHD deficient patients were classified as treated and non-treated groups (rehabilitation with or without 50.000 IU cholecalciferol weekly for two months).The results of treatment were compared with vitamin D sufficient group as control. All patients were followed-up for 6 months. Results: After two months of treatment, in both vitamin D treated and non-treated groups the intensity of BPPV decreased significantly as compared with control (P=0.001 for both groups) but at endpoint, the intensity of BPPV aggravated and regressed to the baseline value in vitamin D deficient non-treated group (P=0.001) whereas, in vitamin D treated group, improvement of BPPV remained stable and unchanged over the study period. Conclusion: This study indicates that correction of vitamin D deficiency in BPPV provides additional benefit to rehabilitation therapy (Epley maneuver) regarding duration of improvement. These findings suggest serum 25-OHD measurement in recurrent BPPV. PMID:27386060

    Having benign paroxysmal positional vertigo (BPPV) puts patients at a significantly higher risk of falling. It is poorly recognised and diagnosis is frequently delayed. BPPV has been studied in outpatient settings, but there have been no studies looking at the prevalence in patients admitted with falls. This study aims to establish how common BPPV is in these patients.For a 4-month period, patients admitted on an unselected medical take were screened for an admission precipitated by a fall. Patients who consented were assessed for BPPV using the Dix-Hallpike manoeuvre. Patients who tested positive were treated using the Epley manoeuvre. The assessments were carried out by specialist physiotherapists who were experienced at assessing and diagnosing patients with peripheral vestibular disorders. Out of the 111 patients initially identified, 37 (33%) were considered to be appropriate and consented to be part of the study. Of these, 20 patients (54%) had a positive Dix-Hallpike manoeuvre.Of the patients included in the study, over half tested positive for BPPV. This merits further study. Potentially, there is a proportion of patients admitted with falls who have an easily treatable contributing factor that is not being identified with standard practice. PMID:27481376

Methods Ninety-two HSC-BPPV patients who were diagnosed by head roll test (HRT were enrolled, and then further tested with 'bow and lean test' (BLT between Oct 1, 2010 and Sep 30, 2011. They were treated by Barbecue maneuver or Brandt-Daroff exercise on the basis of HRT and BLT tests. The positive rate of BLT test was analyzed, and its accuracy for diagnosis and success rate for treatment of HSC-BPPV were compared between HRT and BLT. Results Among the 92 patients, 83(90.2% of them showed BLT nystagmus. Fifty-seven of 83 (68.7% patients showed both bowing nystagmus and leaning nystagmus, and 18(21.7% and 8(9.6% respectively showed bowing nystagmus alone or leaning nystagmus alone. Among 92 patients, 74(80.4% of them the affected side could be determined by HRT with 69 BLT positive and 5 BLT negative. Among the 69 BLT-positive patients, 60 patients showed the same result of HRT, and successful result was achieved by manipulation. 9 patients showed different result between BLT and HRT, in whom manipulation failed according to the result of HRT, but succeeded when manipulation was performed according to BLT. In 18 patients(19.6% it was not able to determine the affected side by HRT, but in 14 patients manipulation was successful when BLT result was applied. In 4 patients BLT failed to evoke nystagmus, but after practicing Brandt-Daroff exercise, vertigo and HRT nystagmus disappeared 3 days later. Among the 92 patients, 65(70.7% were cured according to HRT, while 83(90.2% got successful result according to BLT(P < 0.05. Conclusion The positive rate and accuracy for HSC-BPPV by BLT are high. It is a useful method for determining the affected side in HSC-BPPV, and to provide the basis for selecting effective manipulation treatment.

    interconnecting otoconia. Consequently, otoconia detached from each other may be released into the endolymphatic space by minor mechanical disturbances. In humans, benign positional vertigo (BPV) is believed to result from translocation of otoconia from the endolymphatic space into the semi-circular canals rendering their receptors susceptible to stimulation by gravity causing severe attacks of vertigo. The combinations of these observations in humans, together with the presented animal experiments, provide a tentative pathogenetic basis of the early stage of BPV. PMID:22841569

    As possible candidate screening instruments for benign paroxysmal positional vertigo (BPPV), studies to validate the Dizziness Handicap Inventory (DHI) sub-scale (5-item and 2-item) and total scores are rare in China. From May 2014 to December 2014, 108(55 with and 53 without BPPV) patients complaining of episodic vertigo in the past week from a vertigo outpatient clinic were enrolled for DHI evaluation, as well as demographic and other clinical data. Objective BPPV was subsequently determined by positional evoking maneuvers under the record of optical Frenzel glasses. Cronbach's coefficient α was used to evaluate the reliability of psychometric scales. The validity of DHI total, 5-item and 2-item questionnaires to screen for BPPV was assessed by receiver operating characteristic (ROC) curves. It revealed that the DHI 5-item questionnaire had good internal consistency (Cronbach's coefficient α = 0.72). Area under the curve of total DHI, 5-item and 2-item scores for discriminating BPPV from those without was 0.678 (95 % CI 0.578-0.778), 0.873(95 % CI 0.807-0.940) and 0.895(95 % CI 0.836-0.953), respectively. It revealed 74.5 % sensitivity and 88.7 % specificity in separating BPPV and those without, with a cutoff value of 12 in the 5-item questionnaire. The corresponding rate of sensitivity and specificity was 78.2 and 88.7 %, respectively, with a cutoff value of 6 in 2-item questionnaire. The present study indicated that both 5-item and 2-item questionnaires in the Chinese version of DHI may be more valid than DHI total score for screening objective BPPV and merit further application in clinical practice in China.

    Full Text Available Introducción. El vértigo posicional paroxístico benigno (VPPB es el vértigo más frecuente, con una prevalencia anual del 1,6% en la población general. Puede ser causado por traumatismo craneal. El VPPB se desencadena con determinados movimientos cefálicos, como tumbarse en el sillón odontológico en posición supina. Los objetivos de este estudio son determinar la incidencia de presentación de VPPB durante los procedimientos dentales y analizar la incidencia de VPPB yatrógeno tras traumatismos craneales realizados con el osteótomo dental. Material y métodos. El estudio se ha realizado en un Centro Odontológico Integral, sobre pacientes consecutivos. Es un estudio observacional prospectivo. En cada paciente tratado, se investigó, por anamnesis y observación directa, temor a presentar vértigo al reclinar el sillón hasta la horizontal o desencadenamiento del mismo al hacerlo, o si hubo vértigo en los días ulteriores al uso el osteótomo. Se han excluido pacientes menores de 30 años y aquellos con antecedentes vestibulares. Resultados. Hemos encontrado que un 1,7% de pacientes mayores de 30 años tienen temor a presentar vértigo si van a ser tumbados en posición horizontal, pero sólo el 0,17% de los mismos han presentado un verdadero VPPB al hacerlo. 1.3% de los sujetos en los que se uso el osteótomo durante el procedimiento dental presentaron un VPPB yatrógeno.

    Benign paroxysmal positional vertigo (BPPV) constitutes a major proportion of the population with peripheral vestibulopathies. Although the freely floating otoconia within the semicircular canals is responsible for the symptoms of BPPV, the source of the otoconia debris is mainly believed to be the otolith organs. Therefore, the pathology in either or both the otolith organs appears a logical proposition. Cervical and ocular vestibular-evoked myogenic potentials (cVEMP and oVEMP), being the tests for functional integrity of the otolith organs, appear promising for investigating otolith involvement in BPPV. While recent evidences are suggestive of equivocal findings for cVEMP, there are only a few studies on oVEMP. Additionally, both these potentials have never been explored in the same set of individuals with BPPV. Therefore, the present study aimed to evaluate the functional integrity of the otolith organs through cVEMP and oVEMP in individuals with posterior canal BPPV. Thirty-one individuals with unilateral posterior canal BPPV and 31 age- and gender-matched healthy controls underwent 500 Hz tone-burst-evoked cVEMP and oVEMP. The results demonstrated no significant group difference on any of the cVEMP parameters (p > 0.05). A similar trend was noticed for the latency-related parameters of oVEMP. However, the peak-to-peak amplitude was significantly smaller in the affected ears of individuals with BPPV than their unaffected ears and the ears of healthy controls (p < 0.05). The BPPV group showed significantly higher inter-aural amplitude difference ratio than the healthy controls (p < 0.05). Further, the sensitivity and specificity of oVEMP were also found to be far superior to those of cVEMP. Thus, the outcome of the present study revealed involvement of utricle rather than saccule in posterior canal BPPV, and therefore, oVEMP appears to be better suited to clinical investigation than cVEMP in individuals with posterior canal BPPV.

    Full Text Available Vertigo, was provoked and right torsional up-beat nystagmus was observed in a 47-year-old patient when she was placed into the right Hallpike-Dix test position using infrared goggle technology. The clinical diagnosis was benign paroxysmal positional vertigo (BPPV, specifically right posterior canalithiasis, resulting from a mild traumatic brain injury (TBI suffered approximately six-months earlier. Previous medical consultations did not include vestibular system examination, and Meclizine was prescribed to suppress her chief complaint of vertigo. Ultimately, the patient was successfully managed by performing two canalith repositioning maneuvers during a single clinical session. The patient reported 100% resolution of symptoms upon reexamination the following day, and the Hallpike-Dix test was negative. Continued symptom resolution was subjectively reported 10 days postintervention via telephone consultation. This case report supports previous publications concerning the presence of BPPV following TBI and the need for inclusion of vestibular system examination during medical consultation.

    Full Text Available IntroductionDespite being a common disease, data on vertigo management in a real-world setting are scarce. AimsTo provide information on the vertigo and its management in a real-world setting.Materials and MethodsData were collected from 4,294 patients with vertigo in 13 countries over 28 months via a multi-national, non-interventional observational study (the so-called REVERT registry. Data included medical history and details of anti-vertigo therapy. ‘Clinical global impression’ (CGI of severity (CGI-S was assessed at baseline (V1 and then at 6 months follow-up (V2 along with CGI change (CGI-C. All variables were analysed descriptively. ResultsThe majority of patients were female, >40 years of age, and almost half had co-morbid cardiovascular disease. Diagnoses were split into 4 categories: 37.2% ‘other vertigo of peripheral vestibular origin’, 26.9% benign paroxysmal positional vertigo (BPPV, 20.5% ‘peripheral vestibular vertigo of unknown origin’ and 15.4% Menière’s disease (MD. Betahistine was the most commonly prescribed therapy prior to and after enrolment, and was followed by piracetam, ginkgo biloba and diuretics. MD had the highest proportion of betahistine treated patients. Almost half of patients were ‘moderately ill’ at V1 based on CGI-S. At V2, patient distribution moved towards ‘less severe illness’ (91.0% improved.The greatest improvements were in the more severely ill, and those with BPPV or ‘other vertigo of peripheral origin’. ConclusionsThere was a reduction in illness severity over the course of the study, some of which is likely to be due to pharmacological intervention. Further studies are needed to confirm these results.

    2003-11-01

    Benign paroxysmal positional vertigo (BPPV) is a mechanical disorder of the vestibular system where micron-size crystals abnormally drift into the semicircular canals of the inner ear that sense angular motion of the head. Sedimentation of these crystals causes sensation of motion after true head motion has stopped: vertigo results. The usual clinical treatment is through a series of head maneuvers designed to move the particles into a less sensitive region of the canal system. We present a three-dimensional model to simulate treatment of BPPV by determining the complete hydrodynamic motion of the particles through the course of a therapeutic maneuver while using a realistic representation of the actual geometry. Analyses of clinical maneuvers show the parameter range for which they are effective, and indicate inefficiencies in current practice. In addition, an optimization process determines the most effective head maneuver, which significantly differs from those currently in practice.

    Objective By analysing the results of clinical and laboratory examinations in 9 migraine patients with vertigo or dizziness, we aimed to recognize the relationship between migraine and vertigo, and to improve the diagnosis and treatments of the patients. Methods Nine migraine patients with vertigo/dizziness were selected from our hospital. Besides the detailed questionnaire on the medical history, clinical and laboratory examinations, including neurological examination, vestibule functioning, hearing tests and head CT/MR1, were adopted in each patient, so as to exclude the cases caused by central and vestibule related vertigo. Results Among the 9 migraine patients with vertigo /dizziness, there were 2 cases of hasilar migraine, 3 cases of migraine without aura, and 6 cases of migrainous vertigo (MV, in which 2 migraine patients changed to MV). In the 6 MV patients, vertigo or dizziness occurred several seconds to one hour prior to the headache in 3 cases, post headache in 1 case and simultaneously with headache in 1 case. There was one migraine case, whose headache never occurred together with vertigo, called migraine equivalent. Conclusions MV is a special type of migraine syndrome associated with vertigo or dizziness due to basilar migraine. The diagnosis needs to be distinguished clearly from Meniere' s disease, benign paroxysmal positional vertigo, posterior circulation ischemia (PCI), etc.%目的 分析9例偏头痛伴眩晕/头晕患者的临床及实验室检查结果,探讨头痛与眩晕/头晕的关系,以利正确诊治.方法 作者医院收治的偏头痛伴眩晕/头晕患者9例,对所有患者均详细收集病史,并进行神经系统查体以及前庭功能、听力检查和头颅CT/MRI等实验室检查,以除外中枢性和耳源性眩晕.结果 9例偏头痛伴眩晕/头晕患者中,基底型偏头痛2例,无先兆偏头痛3例,偏头痛性眩晕( migrainous vertigo,MV)6例(其中2例为无先兆偏头痛发作数年后和50

    2016-01-01

    Symptoms referable to disorders affecting the inner ear and vestibulocochlear nerve (eighth cranial nerve) include dizziness, vertigo, tinnitus, and hearing loss, in various combinations. Similar symptoms may occur with involvement of the central nervous system, principally the brainstem and cerebellum, to which the vestibular and auditory systems are connected. Imaging choices should be tailored to patient symptoms and the clinical context. Computed tomography (CT) should be used primarily to assess bony structures. Magnetic resonance imaging (MRI) should be used primarily to assess soft-tissue structures. Vascular imaging by angiography or venography should be obtained when vascular lesions are suspected. No imaging should be obtained in patients with typical presentations of common peripheral vestibular or auditory disorders. In current clinical practice, neuroimaging is often overused, especially CT in the assessment of acute dizziness and vertigo in the emergency department. Despite low sensitivity for ischemic strokes, CT is often used to rule out neurologic causes. When ischemic stroke is the principal concern in acute vestibular presentations, imaging should almost always be by MRI with diffusion-weighted images, rather than CT. In this chapter, we describe recommended strategies for audiovestibular imaging based on patient symptoms and signs. PMID:27430449

    Objective To identify common etiologies, clinical characteristics and appropriate diagnostic techniques in preschool children with vertigo. Methods The authors retrospectively analyzed the clinical characteristics, process of diagnosis and treatment in 12 vertigo-suffering children aging from 14 months to 6.5 years, and their parents' attitude toward the diagnostic techniques. Results (l) Etiologies of vertigo in the 12 children included secretory otitis media (SOM, n=3), benign paroxysmal vertigo (BPV, n=3), inner ear malformation (n=3), benign paroxysmal positional vertigo (BPPV, n=2) and Meniere' s disease (MD, n=l). (2) The younger the child, the fewer typical complaints of vertigo, instead of recurrent falls, difficulties in walking, poor balance and clumsiness, fear or panic. The youngest child that complained of vertigo was 5.5 years old. None of the children were able to describe the details of their vertigo episodes. (3) Among all the diagnostic techniques, vertigo questionnaire was the most acceptable to parents, and vestibular tests were the least. Conclusion Common etiologies of preschool children vertigo include SOM, BPV and inner ear malformation, Sufferers younger than 5 years seldom complain of vertigo.

  5. Benign oral pathology as a cause of false positive 131I uptake in thyroid carcinoma

    International Nuclear Information System (INIS)

    Full text: We present three thyroidectomised patients with a history of thyroid carcinoma who had non-metastatic 131I uptake due to benign oral pathology. A salivary gland study suggested impaired function but no obstruction was demonstrated on a sialogram. The symptoms resolved on antibiotic therapy and a subsequent 131I study was normal. A subsequent thallium study demonstrated physiological tracer distribution. A 35-year-old female with papillary cell carcinoma of the thyroid demonstrated a focus of uptake on the right hemi-mandible following both a diagnostic and a therapeutic dose of 131I. This area was tender and an OPG confirmed an area of liquefaction at this site. A 53-year-old female with medullary cell carcinoma of the thyroid demonstrated a focus of uptake in the right side of the maxilla following a diagnostic administration of 131I. An OPG confirmed an area of liquefaction around the apex of the right upper centre. These three cases illustrate salivary gland and dental inflammation as causes of false positive 131I uptake. It is important to differentiate non-metastatic 131I uptake from that due to functioning metastatic thyroid carcinoma in order to avoid inappropriate treatment with large additional doses of 131I. As in these patients, clinical assessment and the use of anatomical imaging or other isotopes such as thallium or technetium can be helpful in ruling out a mistaken diagnosis of metastasis

    Full Text Available Dizziness is one of the most common reasons patients visit their physicians. Balance control depends on receiving afferent sensory information from several sensory systems: vestibular, optical and proprioceptive. Bioelectric signals, generated by body movements in the semicircular canals and in the otolithic apparatus, are transported via the vestibular nerve to the vestibular nucleus. All four vestibular nuclei, located bilaterally in medial longitudinal fasciculus, are linked with central nervous system structures. These central nervous system structures are involved in maintaining visual stability, spatial orientation and balance control. Nystagmus is a result of afferent signals balance disorders. Nystagmus due to peripheral lesions is conjugate nystagmus, because there is a bilateral central connection. Lesions above the vestibular nuclei induce deficits in synchronization and conjugation of eye movements, thus the nystagmus is dissociated. This paper shows that in peripheral vestibular disorders spontaneous nystagmus is rhythmic, associated, horizontal-rotatory or horizontal, with subjective sensation of dizziness which decreases with time and harmonic signs whose direction coincides with the slow phase of nystagmus and it is associated with mild disorders during pendular stimulation with statistically significant vestibular hypofunction. Spontaneous nystagmus in central vestibular lesions is severe, dissociated, horizontal, rotatory or vertical, without changes related to optical suppression; if vestibular symptoms are present, they are non-harmonic. In central disorders, findings after thermal stimulation are either normal or pathological, with dysrhythmias and inhibition in pendular stimulation. This paper deals with differential diagnosis of vertigo based on anamnesis and clinical examination, as well as objective diagnostic tests. .

    Squires, T M; Hain, T C; Stone, H A; Stone, Howard A.

    2003-01-01

    Benign Paroxysmal Positional Vertigo (BPPV) is a mechanical disorder of the vestibular system, in which calcite particles called otoconia interfere with the mechanical functioning of the fluid-filled semicircular canals normally used to sense rotation. Using hydrodynamic models, we examine the two mechanisms proposed by the medical community for BPPV: cupulolithiasis, in which otoconia attach directly to the cupula (a sensory membrane), and canalithiasis, in which otoconia settle through the canals and exert a fluid pressure across the cupula. Extending known hydrodynamic calculations and making reasonable geometric and physical approximations, we derive an expression for the transcupular pressure $\\Delta P_c$ exerted by a settling solid particle in canalithiasis. By tracking settling otoconia in a model two-dimensional geometry, the cupular displacement and associated eye response (nystagmus) can be calculated quantitatively. Several important features emerge: 1) A pressure amplification occurs as otoconia e...

    A 56-year-old woman underwent near-total thyroidectomy and papillary thyroid carcinoma without extrathyroidal extension was diagnosed. The serum thyroglobulin (Tg) level was 2.4 µg/L, and anti-Tg was negative when serum thyroid-stimulating hormone level was 85 µIU/mL. She received 100 mCi (3.7 GBq) of 131I. Besides the residual thyroid tissue, a focal uptake in the left clavicular bone was seen on posttherapy 131I images. Then, CT and MRI were performed to diagnosis. All imaging findings suggested that it was a benign bone cyst. At 6-month follow-up, the serum Tg level was undetectable with the thyroid-stimulating hormone level of more than 150 µIU/mL.

  15. Comparative study on cases of vertigo and dizziness in the emergency room and otorhinolaryngological clinic

    International Nuclear Information System (INIS)

    We recently studied the characteristics of vertigo and dizziness in 197 patients who first visited the emergency room (ER group) and in 288 patients who first visited the otorhinolaryngological clinic of Minoh City Hospital (ENT group) between January 1 and December 31 of 2009. The ER group can be regarded as representing the hyperacute phase and the ENT group as representing the acute to chronic phase. These two groups were completely distinct. We also subdivided these groups into the high risk subgroup (H subgroup) for cases with the underlying diseases of diabetes mellitus, hypertension, cerebrovascular disease and hyperlipidemia, and the normal subgroup (N subgroup).Comparison of the two groups showed that, in the ER group, a significantly larger numbers of patients had symptoms of peripheral vestibular origin except for benign paroxysmal positional vertigo (BPPV) and Meniere's disease, and a significantly larger number of patients had symptoms of unknown origin in the ENT group. Half of this group may be accounted for by patients with symptoms of peripheral vestibular origin except for BPPV and Meniere's disease in the ER group. In 8 out of 158 patients of the ER group and 1 out of 122 patients of the ENT group, cerebral lesions were not found on CT images but were found with MRI. Careful investigation is necessary in the patients with normal CT findings. Central vestibular lesions were found in 7 out of 197 patients (3.5%) of the ER group and 5 out of 288 patients (1.7%) of the ENT group. The incidence of central lesions tended to be higher in the ER group than in the ENT group. There was no significant difference in the incidence of central lesion among the H and N subgroups of both groups. Careful investigation of the central vestibular lesion is also necessary in the N subgroup. (author)

    Dizziness and vertigo are frequently reported by patients with migraine. In migrainous vertigo (MV), vertigo is causally related to migraine. Patients of MV usually have an attenuated or absent headache with their vertigo as compared with their usual headache of migraine. Here we report three female patients of MV in which administration of triptan was associated with induction (two patients) or exacerbation (one patient) of headache with disappearance of vertigo. We suggest that headache and...

    Full Text Available Vertigo is a common complaint that leads patients to visit physicians of various specialties. Diseases resulting in vestibular vertigo are very diverse and may be caused by lesion of both the central parts of the vestibular system and the peripheral vestibular apparatus. In many cases, its diagnosis can be made from complaints and a history of disease and special bedside tests requiring no sophisticated equipment. Management of vestibular vertigo should aim at treating the underlying disease; vestibular dilators as symptomatic therapy can be effective for several days. Vestibular exercises the efficiency of which can be enhanced by betahistine and other drugs accelerating vestibular compensation should be further needed. Data on the efficacy of betaver (betahistine in patients with vestibular vertigo are given.

    Vertigo, which involves multidisciplinary knowledge, can manifest complicated and varied forms. The key of the diagnosis of vertigo is to distinguish central vertigo from peripheral vertigo. Patients accompanied with obvious otology or neurological signs are easy to diagnose, but the diagnosis of patients with isolated vertigo is challenging. In recent years, in addition to the most important examination of otological and the nervous system, with the developing of the research, bedside evaluation of vertigo patients includes eye position, nystagmus, oculomotor, head movements, posture and gait, which is based on vestibular otolith pathway and oculomotor pathway, greatly enriches the topical diagnostic of vertigo. Standardization of the bedside evaluation of vertigo will further help us identify the central or peripheral vertigo. This article will review the method and clinical signiifcance of the bedside evaluation of vertigo patients.%眩晕的临床表现复杂,涉及多学科知识,眩晕的定位是眩晕诊断的首要问题。伴有明显的耳科或神经系统体征的眩晕患者较易诊断,但仅表现为孤立性眩晕的患者的诊断却极具有挑战性。近年来,随着研究的深入,除了最为重要的神经系统、耳科查体外,基于前庭耳石通路及眼动通路的眼位、眼震、眼动、头动及姿势步态等的床旁检查,亦极大地丰富了眩晕患者的定位诊断学。这些床旁检查方法的规范应用,将有助于医师及时地进行定位诊断,识别中枢还是外周性眩晕。基于此,本文对眩晕床旁检查方法及其相关临床意义做一简要综述。

About 50% of students with spinning vertigo and swaying vertigo also report to have orthostatic dizziness. Most vertigo/dizziness types were confined to less than one minute on average. The proportion of students with any dizziness/vertigo accounting for failure attending school, leisure activities or obliging them to stay in bed were more pronounced for spinning or swaying vertigo.Dizziness and vertigo in grammar school students appear to be as common as in adults. In face of the high period prevalence and clinical relevance of dizziness/vertigo in adolescents there is a need for prevention strategies. Risk factors for dizziness/vertigo need to be assessed to allow for conception of an intervention programme.

    Full Text Available Sarcoidosis is a granulomatous disease of unknown etiology that affects multiple organ systems. Neurological manifestations of sarcoidosis are less common and can include cranial neuropathies and intracranial lesions. We report the case of a 21-year-old man who presented with vertigo and uveitis. Extensive workup including brain imaging revealed enhancing focal lesions. A lacrimal gland biopsy confirmed the diagnosis of sarcoidosis. The patient was initially treated with prednisone, which did not adequately control his symptoms, and then was switched to methotrexate with moderate symptomatic improvement. Our patient had an atypical presentation with vertigo as the predominant manifestation of sarcoidosis. Patients with neurosarcoidosis typically present with systemic involvement of sarcoidosis followed by neurologic involvement. Vertigo is rarely reported as an initial manifestation. This case highlights the importance of consideration of neurosarcoidosis as an entity even in patients that may not have a typical presentation or systemic involvement of disease.

  6. Positive malignant margins in clinically diagnosed and excised benign breast lumps: a five year retrospective study at the Korle-Bu Teaching Hospital, Ghana

    International Nuclear Information System (INIS)

    This study was aimed at utilizing retrospective descriptive data to evaluate the percentage of clinically benign breast lumps that turned out to be histologically malignant and the prevalence of positive tumour margins among the malignant cases. A total of 2,917 registered cases of excised breast lump at the Department of Pathology spanning January 2005 to December 2009 were reviewed to evaluate the presence of malignancy and positive margins. Three hundred and twenty-two (11.0%) of the excised breast lumps were found to contain malignant tumours, out of which 142(44.1%) had positive tumour margins. Size of primary tumour (p=0.001) and histologic subtype (p=0.002) showed significant positive and negative associations in relation to positive tumour margins respectively. No significant association was observed between the positive tumour margins and histologic grade (p=0.363). The study showed that clinically benign breast lumps could be malignant and not completely excised, therefore increasing the risk of local recurrence. Thus, it is recommended that all women with breast lumps have the triad (diagnostic workup) of clinical and radiological assessment, followed with histological studies. (au)

    Cervical vertigo refers to a syndrome with a chief complaint of vertigo arising from cervical verteprae discomfort. In general, cervical vertigo is correlated with but not always caused by cervical spondylopathy,which mainly includes vertebral arterial and sympathetic cervical spondylosis. The vertebral artery insufficiency caused by compression from lateral displacement of the intervertebral dise is very rare, while the sympathetic cervical spondylosis caused by the vertebral instability is much more common. Rigorous criteria have been developed for diagnosis of the latter. Conservative therapy is mainly recommended for treatment of cervical vertigo.%颈性眩晕通常与颈椎病有关,但不一定完全由颈椎病所致.与颈性眩晕有关的主要是椎动脉型和交感型颈椎病.由椎间盘侧突压迫导致的椎动脉供血不足非常罕见,由椎体不稳引起的交感型颈椎病较多,但后者也有其严格的诊断标准.治疗以保守治疗为主.

    Objective: To investigate the value of HSA-Gd-DTPA (Human Serum Albumin-Gadolinium diethylenetriamine pentaacetic acid)-enhanced positive MR lymphography for differentiation of the benign from metastatic lymph nodes. Methods: Twelve New Zealand rabbits weighted at 2.0-2.5 kg were used. Six hyperplastic reactive popliteal lymph nodes were induced by intramuscular injection of 0.5 ml egg yolk emulsion (EYE) into the unilateral hindleg, and six tumor-bearing popliteal lymph nodes were induced by intramuscular injection of 0.5 ml VX2 tumor cell suspension into the unilateral hindleg, the contralateral lymph nodes were chosen as normal control group. MR features before and 24 h after interstitial administration of HSA-Gd-DTPA (0.04 mmol/kg) were analyzed and correlated with pathological findings. Results: The normal, hyperplastic reactive and VX2 tumor-bearing popliteal lymph nodes showed moderate or slightly high signal intensity on unenhanced T1-weighted images and high signal on T2-weighted images. The normal and hyperplastic reactive lymph nodes showed homogeneous and remarkable enhancement on SE T1WI 24 h after the administration of HSA-Gd-DTPA, while 8 metastatic lymph nodes showed ring or patchy enhancement, and 2 metastatic lymph nodes showed no enhancement. Conclusion: HSA-Gd-DTPA-enhanced positive MR lymphography can accurately differentiate the benign from metastatic lymph nodes. (authors)

    Full Text Available Introduction: Vertigo, dizziness, and nausea encompass a spectrum of balance-related symptoms caused by a variety of etiologies. Balance is affected by many systems: Proprioceptive pathways and visual, cerebellar, vestibulocochlear, and vascular / vasovagal systems. Vertigo is a subtype of dizziness, in which a subject, as a result to a dysfunction of the vestibular system, improperly experiments the perception of motion. The most useful clinical subdivision is to categorize vertigo into true vertigo and pseudovertigo, whereas from a pathophysiological point of view, vertigo can be classified into central, peripheral, and psychogenic. It is not easy to identify the cause of vertigo since the patients often are not able to precisely describe their symptoms. An impressive list of drugs may cause vertigo or dizziness. Materials and Methods: The aim of the present study was to analyze the data extracted from the reporting cards of the ADRs (adverse drug reactions, received at our Pharmacovigilance Regional Center (Calabria, Italy in 2012. In particular, the data concerning the occurrence of vertigo and dizziness, after taking certain classes of drugs, have been considered. Results: Our results show that, among the side-effects of different classes of drugs such as anti-convulsants, anti-hypertensives, antibiotics, anti-depressants, anti-psychotics, and anti-inflammatory, also vertigo or dizziness are included. Conclusions: Spontaneous reports of vertigo or dizziness, as side-effect of certain drugs, received at our Pharmacovigilance Center, represented the 5% of all reports in 2012. Considering the high incidence of such an ADR for several drugs′ classes, it can be speculated that under-reporting also affect vertigo and dizziness. Despite the fact that these ADRs might not represent a direct threaten for life, indirectly they can cause secondary damage to patients such as falls, fractures etc. Balance should be accurately monitored during drug use

    Vestibular signals are of significant importance for variable functions including gaze stabilization, spatial perception, navigation, cognition, and bodily self-consciousness. The vestibular network governs functions that might be impaired in patients affected with vestibular dysfunction. It is currently unclear how different brain regions/networks process vestibular information and integrate the information into a unified spatial percept related to somatosensory awareness and whether people with recurrent balance complaints have a neural signature as a trait affecting their development of chronic symptoms of vertigo. Pivotal evidence points to a vestibular-related brain network in humans that is widely distributed in nature. By using resting state source localized electroencephalography in non-vertiginous state, electrophysiological changes in activity and functional connectivity of 23 patients with balance complaints where chronic symptoms of vertigo and dizziness are among the most common reported complaints are analyzed and compared to healthy subjects. The analyses showed increased alpha2 activity within the posterior cingulate cortex and the precuneues/cuneus and reduced beta3 and gamma activity within the pregenual and subgenual anterior cingulate cortex for the subjects with balance complaints. These electrophysiological variations were correlated with reported chronic symptoms of vertigo intensity. A region of interest analysis found reduced functional connectivity for gamma activity within the vestibular cortex, precuneus, frontal eye field, intra-parietal sulcus, orbitofrontal cortex, and the dorsal anterior cingulate cortex. In addition, there was a positive correlation between chronic symptoms of vertigo intensity and increased alpha-gamma nesting in the left frontal eye field. When compared to healthy subjects, there is evidence of electrophysiological changes in the brain of patients with balance complaints even outside chronic symptoms of vertigo

    On November 15, 1967, U.S. Air Force test pilot Major Michael J. Adams was killed while flying the X-15 rocket-propelled research vehicle in a parabolic spaceflight profile. This flight was part of a joint effort with NASA. An electrical short in one of the experiments aboard the vehicle caused electrical transients, resulting in excessive workload by the pilot. At altitude Major Adams inappropriately initiated a flat spin that led to a series of unusual aircraft attitudes upon atmospheric re-entry, ultimately causing structural failure of the airframe. Major Adams was known to experience vertigo (i.e. spatial disorientation) while flying the X-15, but all X-15 pilots most likely experienced vertigo (i.e. somatogravic, or "Pitch-Up", illusion) as a normal physiologic response to the accelerative forces involved. Major Adams probably experienced vertigo to a greater degree than did others, since prior aeromedical testing for astronaut selection at Brooks AFB revealed that he had an unusually high degree of labyrinthine sensitivity. Subsequent analysis reveals that after engine burnout, and through the zenith of the flight profile, he likely experienced the oculoagravic ("Elevator") illusion. Nonetheless, painstaking investigation after the mishap revealed that spatial disorientation (Type II, Recognized) was NOT the cause, but rather, a contributing factor. The cause was in fact the misinterpretation of a dual-use flight instrument (i.e. Loss of Mode Awareness), resulting in confusion between yaw and roll indications, with subsequent flight control input that was inappropriate. Because of the altitude achieved on this flight, Major Adams was awarded Astronaut wings posthumously. Understanding the potential for spatial disorientation, particularly the oculoagravic illusion, associated with parabolic spaceflight profiles, and understanding the importance of maintaining mode awareness in the context of automated cockpit design, are two lessons that have direct

    Full Text Available El vértigo en el niño es una patología poco frecuente, pero además ha sido subvalorada y poco citada en la literatura hasta la década de los 80. Definido como la sensación de movimiento del propio cuerpo o del ambiente circundante, es un síntoma que se origina por múltiples causas. En este artículo se describen los diferentes cuadros de vértigo en el niño y las características clínicas que permiten su identificación. Especial importancia tiene una historia clínica detallada y un examen otológico y neurológico completos para efectuar el diagnóstico. Destacan la otitis media y las variantes migrañosas, en especial el vértigo paroxístico benigno, como las causas más frecuentes de vértigo en la infancia. El adecuado enfrentamiento del niño con vértigo, que parte por la sospecha clínica en un paciente que puede no dar las claves anamnésticas por su corta edad, es fundamental para establecer el diagnóstico correcto y efectuar los tratamientos adecuados según la causa de vértigo en cada caso.Vertigo is uncommon in children, but it is usually underecognized and it has not been well referenced in the medical literature until the 1980s. It is defined as a subjective sensation of movement of the body or the surrounding, and it is a symptom that may have multiple causes. This paper reviews the different types of vertigo in children, emphasizing their clinical features that may be useful in establishing the diagnosis. Of particular relevance is an accurate clinical history and a complete otologic and neurologic examination. More common causes of pediatric vertigo are otitis media and migraine variants, particularly benign paroxysmal vertigo. An appropriate approach to the child with vertigo begins with the clinical suspicion, based on a detailed clinical history and examination, and specific tests. Diagnosis should be followed by adequate symptomatic treatment and management of the underlying specific causes.

    We were interested in determining the efficacy of Arlevert therapy in vertigo and tinnitus patients, especially as it compared to the efficacy of the drug's two component agents, dimenhydrinate and cinnarizine. We conducted a comparative, randomized, double blind, multicenter, parallel group study involving a group of patients (n = 122) with vertigo and tinnitus of peripheral or central origin. The three test groups, nearly equal in size, were administered three times daily for 4 weeks one of the three agents being evaluated. To evaluate therapeutic success, we studied patients' vertigo symptoms, concomitant vegetative symptoms, CCG parameters, and electronystagmographic and audiometric parameters. We also obtained subjective assessments of outcomes from the test patients. Our results led us to conclude that Arlevert is more effective than either of its component drugs alone in treating vertigo and tinnitus. The drug also was well tolerated. PMID:10753423

    Background Of the 2007 Cystic Fibrosis Transmembrane Conductance Regulator (CFTR) mutations, 202 have been assigned disease liability. California’s racially diverse population, along with CFTR sequencing as part of newborn screening model, provides the opportunity to examine the phenotypes of children with uncategorized mutations to help inform disease liability and penetrance. Methods We conducted a retrospective cohort study based on children screened from 2007 to 2011 and followed for two to six years. Newborns that screened positive were divided into three genotype groups: those with two CF-causing mutations (CF-C); those with one mutation of varying clinic consequence (VCC); and those with one mutation of unknown disease liability (Unknown). Sweat chloride tests, pancreatic sufficiency status, and Pseudomonas aeruginosa colonization were compared. Results Children with two CF-causing mutations had a classical CF phenotype, while 5% of VCC (4/78) and 11% of Unknown (27/244) met diagnostic criteria of CF. Children carrying Unknown mutations 2215insG with D836Y, and T1036N had early and classical CF phenotype, while others carrying 1525-42G>A, L320V, L967S, R170H, and 296+28A>G had a benign clinical presentation, suggesting that these are non-CF causing. Conclusions While most infants with VCC and Unknown CFTR mutations do not meet diagnostic criteria for CF, a small proportion do. These findings highlight the range of genotypes and phenotypes in the first few years of life following CF newborn screening when CFTR sequencing is performed. PMID:27214204

    To investigate brain lesions and their locations in patients with central vertigo, as seen on MR imaging. We retrospectively reviewed MR images of 85 patients with central type vertigo diagnosed on the basis of clinical symptoms and vestibular function test(VFT), and analyzed lesions fand their locations. Those located along the known central vestibular pathway were included in our study. In 29 of 85 patients(34%), lesions considered to be associated with central vertigo were detected on MR imaging. These included infarction(18 patients), hemorrhage(5), tumor(2), cavernous angioma(1), cerebellopontine angle cyst(1), tuberous sclerosis(1) and olivopontocerebellar atrophy (1);they were located in the parietal lobe(6 patients), the lateral medulla(5), the pons(5), the middle cerebellar peduncle(4), the corona radiata(3), and the cerebellar vermis(3). Thirty-eight cases showed high signal intensity lesions in deep cerebral matter, the basal ganglia, and pons but these were considered to be unrelated to central vertigo. MR imaging could be a useful tool for the evaluation of patients with central vertigo.=20.

    2015-04-01

    Vertigo, dizziness, and disequilibrium are common symptoms following concussion or mild traumatic brain injury (mTBI). Dizziness and vertigo may be the result of trauma to the peripheral vestibular system or the central nervous system, or, in some cases, may be due to anxiety, depression, or posttraumatic stress disorder; these mechanisms are not mutually exclusive. While most peripheral vestibular disorders can be identified by testing and examination, those without inner-ear causes that have persisting complaints of dizziness and motion sickness are more difficult to understand and to manage. Some of these patients exhibit features compatible with vestibular migraine and may be treated successfully with migraine-preventative medications. This paper reviews the nonotogenic causes of persisting dizziness, the possible mechanisms, and the pathophysiology, as a framework for patient management and for future research. PMID:25728715

    A 60-year-old man had incidental finding of a multilobular 8 × 7 × 7-cm mass identified posterior to the urinary bladder in continuity with the prostate. The man's prostate-specific antigen was 1.87, and he denied any lower urinary tract symptoms. A transrectal ultrasound-guided biopsy demonstrated benign prostatic tissue. A computed tomography-guided needle aspiration demonstrated a benign epithelium-lined cyst, likely prostatic in origin. Benign prostatic hyperplasia is a proliferation of prostatic epithelial and stromal cells. Although prostatic hyperplasia is usually restricted to the prostate gland, hyperplastic nodules occasionally protrude outside the prostate and rarely form exophytic pelvic masses. PMID:20869104

    Cervicogenic vertigo was known as Bow hunter's syndrome. Occlusion of vertebral artery causes vertebrobasilar insufficiency and we reported cervicogenic vertigo case which was treated by simple decompression of transverse foramen of C1. The patient was 48 years old female who had left side dominant vertebral artery and vertigo was provoked when she rotated her head to right side. Angiography showed complete obliteration of blood flow of left vertebral artery when her head was rotated to right side. The operation was decompression of left vertebral artery at C1 level. Posterior wall of transverse foramen was resected and vertebral artery was exposed and decompressed. After surgery, vertigo of the patient was disappeared, and angiography showed patent left vertebral artery when her head was rotated to right side. Vertigo caused by compression of cervical vertebral artery could be treated by decompression without fusion or instrumentation, especially in C1 transverse foramen. PMID:25346772

    Objective:To observe the therapeutic effects of filiform needle acupuncture combined with dermal needle tapping for vertebrobasilar ischemic vertigo. Methods: Based on the etiopathogenesis of TCM, the disease is caused by turbid phlegm clouding the heart orifice combined with wind, leading to insufficient nourishment of the brain due to deficiency of blood. Fenglong (ST 40) was punctured with filiform needle to resolve phlegm; Fengchi (GB 20) to dispel wind; Baihui (GV 20) to stop dizziness; and Lieque (LU 7) to widen the inner diameter of the vertebral arteries and increase peak systolic velocity and minute blood flow volume, so as to improve blood supply to the vertebral arteries. Dazhui (GV 14) was stimulated by tapping with a dermal needle to improve blood supply to the head. Results: Of 50 patients in this series, 39 cases (78%) were cured,6 cases (12%) relieved, 4 cases (8%) improved, and 1 case (2%) failed, with a total effective rate of 98%.Conclusion: Acupuncture combined with dermal needle tapping is an effective therapy for treating vertebrobasilar ischemic vertigo.

  14. Diagnosing Stroke in Acute Vertigo: The HINTS Family of Eye Movement Tests and the Future of the "Eye ECG".

    2015-10-01

    Patients who present to the emergency department with symptoms of acute vertigo or dizziness are frequently misdiagnosed. Missed opportunities to promptly treat dangerous strokes can result in poor clinical outcomes. Inappropriate testing and incorrect treatments for those with benign peripheral vestibular disorders leads to patient harm and unnecessary costs. Over the past decade, novel bedside approaches to diagnose patients with the acute vestibular syndrome have been developed and refined. A battery of three bedside tests of ocular motor physiology known as "HINTS" (head impulse, nystagmus, test of skew) has been shown to identify acute strokes more accurately than even magnetic resonance imaging with diffusion-weighted imaging (MRI-DWI) when applied in the early acute period by eye-movement specialists. Recent advances in lightweight, high-speed video-oculography (VOG) technology have made possible a future in which HINTS might be applied by nonspecialists in frontline care settings using portable VOG. Use of technology to measure eye movements (VOG-HINTS) to diagnose stroke in the acute vestibular syndrome is analogous to the use of electrocardiography (ECG) to diagnose myocardial infarction in acute chest pain. This "eye ECG" approach could transform care for patients with acute vertigo and dizziness around the world. In the United States alone, successful implementation would likely result in improved quality of emergency care for hundreds of thousands of peripheral vestibular patients and tens of thousands of stroke patients, as well as an estimated national health care savings of roughly $1 billion per year. In this article, the authors review the origins of the HINTS approach, empiric evidence and pathophysiologic principles supporting its use, and possible uses for the eye ECG in teleconsultation, teaching, and triage.

    The mechanism of vertigo is unclear. Generally, the peak time or the latency of blood oxygenation level dependent (BOLD) effect is about 6 s. However, clinically, the latency of vertigo or nystagmus induced by caloric stimulations is much longer than 6 s, commonly about 30 s induced by water of 30 deg. C or 44 deg. C. We hypothesize that there is an inhibitive power or mechanism for the occurrence of vestibular vertigo, since it is an unpleasant feeling. The caloric test was performed in healthy volunteers during the BOLD fMRI scanning. The overlaid results of statistical parametric mapping (SPM) showed that three brain regions showed neural activation during vestibular dizziness while deactivation occurred in response to cold water simulation: (1) supplementary motor area (SMA); (2) middle temporal area/medial superior temporal area (MT/MST); (3) visual association area (BA19). The time course of the regions further demonstrated that the signal decreased during the cold-water stimulation and increased during the period of vertigo. We therefore further hypothesize that there may be two forces for the production of vertigo: inhibitory power (IP) and promotive power (PP). The delayed onset of vertigo was the result of the interaction between IP and PP. All of our findings, for the first time, suggested such an original mechanism of vertigo.

A firm diagnosis can only come from an electronic microscopy or immunohistological examination of the tumour. Diagnostic accuracy and diligent follow up are essential because, although the tumour is considered benign, it does tend towards local recurrence. [Int J Res Med Sci 2014; 2(2.000: 762-764

  18. Digital subtraction angiography in patients with central vertigo

    International Nuclear Information System (INIS)

    Digital subtraction angiography (DSA) is a recently developed non-invasive intravenous angiography which has become possible through real time digital subtraction of x-ray transmission data from an image intensifier and television system. The output signals of the image intensifier-television camera system are digitized by an analog-digital converter. The digital information, 512x512 pixels and 9 bits deep, is fed into the image processing assembly after logarithmic amplification, where 2-8 frames are added and subtracted from mask images for the final digital images. Intravenous digital subtraction angiography was performed in 21 patients with intractable dizzy spells of central origin resistant to treatment. These patients showed some signs of CNS disturbance, although there were no significant findings on CT scans. Surprisingly, findings were abnormal in 14 of 21 patients (66.7%). DSA is, therefore, considered to be an important aid in the diagnosis of vertigo of the central type. (J.P.N.)

    Full Text Available Fibrous histiocytomas (FHs are mesenchymal tumors that may be benign or malignant. Ocular involvement by FHs is infrequent and primarily limited to the orbit. Rarely, FHs can also involve the conjunctiva and perilimbal area. We report the case of a 38-year-old male with lid, conjunctival, and neck FHs. The diagnosis was confirmed by histopathology.

  1. Benign gastric filling defect

    International Nuclear Information System (INIS)

    The gastric lesion is a common source of complaints to Orientals, however, evaluation of gastric symptoms and laboratory examination offer little specific aid in the diagnosis of gastric diseases. Thus roentgenography of gastrointestinal tract is one of the most reliable method for detail diagnosis. On double contract study of stomach, gastric filling defect is mostly caused by malignant gastric cancer, however, other benign lesions can cause similar pictures which can be successfully treated by surgery. 66 cases of benign causes of gastric filling defect were analyzed at this point of view, which was verified pathologically by endoscope or surgery during recent 7 years in Yensei University College of Medicine, Severance Hospital. The characteristic radiological picture of each disease was discussed for precise radiologic diagnosis. 1. Of total 66 cases, there were 52 cases of benign gastric tumor 10 cases of gastric varices, 5 cases of gastric bezoar, 5 cases of corrosive gastritis, 3 cases of granulomatous disease and one case of gastric hematoma. 2. The most frequent causes of benign tumors were adenomatous polyp (35/42) and the next was leiomyoma (4/42). Others were one of case of carcinoid, neurofibroma and cyst. 3. Characteristic of benign adenomatous polyp were relatively small in size, smooth surface and were observed that large size, benign polyp was frequently type IV lesion with a stalk. 4. Submucosal tumors such as leiomyoma needed differential diagnosis with polypoid malignant cancer. However, the characteristic points of differentiation was well circumscribed smooth margined filling defect without definite mucosal destruction on surface. 5. Gastric varices showed multiple lobulated filling defected especially on gastric fundus that changed its size and shape by respiration and posture of patients. Same varices lesions on esophagus and history of liver disease were helpful for easier diagnosis. 6. Gastric bezoar showed well defined movable mass

    Direction changing horizontal positional nystagmus can be observed in a variety of central and peripheral vestibular disorders. We tested sixty subjects with horizontal positional nystagmus and vertigo on the Epley Omniax(®) rotator. Monocular video recordings were performed with the right or left ear down, in the supine and prone positions. Nystagmus slow-phase velocity (SPV) was plotted as a function of time. Thirty-one subjects diagnosed with horizontal canalolithiasis had paroxysmal horizontal geotropic nystagmus with the affected ear down (onset 0.8 ± 1 s, range 0-4.9 s, duration 11.7-47.9 s, peak SPV 79 ± 67°/s). The SPV peaked at 5-20 s and declined to 0 by 60 s; at 40 s from onset, the average SPV was 1.8 % of the peak. Nine subjects diagnosed with cupulolithiasis had persistent apogeotropic horizontal nystagmus (onset 0.7 ± 1.4 s, range 0-4.3 s). Peak SPV was 54.2 ± 31.8°/s and 26.6 ± 12.2°/s with unaffected and affected ears down, respectively. At 40 s, the average SPV had decayed to only 81 % (unaffected ear down) and 65 % (affected ear down) of the peak. Twenty subjects were diagnosed with disorders other than benign positional vertigo (BPV) [vestibular migraine (VM), Ménière's Disease, vestibular schwannoma, unilateral or bilateral peripheral vestibular loss]. Subjects with VM (n = 13) had persistent geotropic or apogeotropic horizontal nystagmus. On average, at 40 s from nystagmus onset, the SPV was 61 % of the peak. Two patients with Ménière's Disease had persistent apogeotropic horizontal nystagmus; the peak SPV at 40 s ranged between 28.6 and 49.5 % of the peak. Symptomatic horizontal positional nystagmus can be observed in canalolithiasis, cupulolithiasis and diverse central and peripheral vestibulopathies; its temporal and intensity profile could be helpful in the separation of these entities.

  6. Posterior semicircular canal dehiscence: a morphologic cause of vertigo similar to superior semicircular canal dehiscence

    International Nuclear Information System (INIS)

    Heading Abstract.The aim of this study was to assess imaging findings of posterior semicircular dehiscence on computed tomography and to evaluate incidence of posterior and superior semicircular canal dehiscence in patients presenting with vertigo, sensorineuronal hearing loss or in a control group without symptoms related to the inner ear. Computed tomography was performed in 507 patients presenting either with vertigo (n=128; 23 of these patients suffered also from sensorineuronal hearing loss), other symptoms related to the inner ear, such as hearing loss or tinnitus (n=183) or symptoms unrelated to the labyrinth (n=196). All images were reviewed for presence of dehiscence of the bone, overlying the semicircular canals. Twenty-nine patients had superior semicircular canal dehiscence. Of these patients, 83% presented with vertigo, 10% with hearing loss or tinnitus and the remaining 7% with symptoms unrelated to the inner ear. In 23 patients dehiscence of the posterior semicircular canal was encountered. Of these patients, 86% presented with vertigo, 9% with hearing loss or tinnitus and 5% with symptoms unrelated to the inner ear. Defects of the bony overly are found at the posterior semicircular canal, in addition to the recently introduced superior canal dehiscence syndrome. Significant prevalence of vertigo in these patients suggests that posterior semicircular canal dehiscence can cause vertigo, similar to superior semicircular canal dehiscence. (orig.)

  8. Infantile benign subdural effusion

    International Nuclear Information System (INIS)

    Twenty cases of infants with low density area over the frontal lobes on CT scans mimicking cortical atrophy were reported. Almost all cases showed increased intracranial pressure of slight degree associated with delayed milestones. Marginal low density over the frontal lobes disappeared and the infants developed almost normally without operations in many cases. The lesion might be called ''Infantile benign subdural effusion'' and should be treated conservatively. (author)

    Background. In pediatrics, pneumatosis intestinalis (PI) is usually due to necrotizing enterocolitis in premature newborns. Beyond infancy, PI is uncommon. ''Benign pneumatosis'' is PI in patients with few or no symptoms that resolves with conservative management. Objective. Our goal was to better characterize benign PI in children. Our investigation focused on identifying underlying risk factors, symptoms at time of diagnosis, management and outcome. Materials and methods. Available medical records and radiographs of children with pneumatosis intestinalis from 1990 to 1998 were reviewed for underlying conditions, symptoms at time of radiographs, management and outcome. Results. Thirty-seven children (mean age 4 years) were included. Thirty-two children had identifiable risk factors. Twenty -five children were immunocompromised by their underlying conditions or therapeutic regimen. Thirty-five children were managed conservatively with resolution of PI. Two patients, however, required surgery and one patient died. Conclusion. Benign pneumatosis does occur in children. The majority have underlying risk factors, most commonly related to immunosuppression. Clinical deterioration is the most useful indicator for surgical intervention. In most patients PI resolves with conservative management. (orig.)

  10. DIZZYNET-a European network initiative for vertigo and balance research: visions and aims.

    Science.gov (United States)

    Zwergal, Andreas; Brandt, Thomas; Magnusson, Mans; Kennard, Christopher

    2016-04-01

    Vertigo is one of the most common complaints in medicine. Despite its high prevalence, patients with vertigo often receive either inappropriate or inadequate treatment. The most important reasons for this deplorable situation are insufficient interdisciplinary cooperation, nonexistent standards in diagnostics and therapy, the relatively rare translations of basic science findings to clinical applications, and the scarcity of prospective controlled multicenter clinical trials. To overcome these problems, the German Center for Vertigo and Balance Disorders (DSGZ) started an initiative to establish a European Network for Vertigo and Balance Research called DIZZYNET. The central aim is to create a platform for collaboration and exchange among scientists, physicians, technicians, and physiotherapists in the fields of basic and translational research, clinical management, clinical trials, rehabilitation, and epidemiology. The network will also promote public awareness and help establish educational standards in the field. The DIZZYNET has the following objectives as regards structure and content: to focus on multidisciplinary translational research in vertigo and balance disorders, to develop interdisciplinary longitudinal and transversal networks for patient care by standardizing and personalizing the management of patients, to increase methodological competence by implementing common standards of practice and quality management, to internationalize the infrastructure for prospective multicenter clinical trials, to increase recruitment capacity for clinical trials, to create a common data base for patients with vertigo and balance disorders, to offer and promote attractive educational and career paths in a network of cooperating institutions. In the long term, the DIZZYNET should serve as an internationally visible network for interdisciplinary and multiprofessional research on vertigo and balance disorders. It ideally should equally attract the afflicted patients and

    vestibular central vertigo were more common in male(P<0.001), older(P=0.009), shorter in course(P<0.001). The symptoms of diplopia(P<0.001), hemianesthesia weakness(P<0.001), slurred speech(P<0.001) were more often in patients with vestibular central vertigo. And cochlear symptoms(P=0.021) were more frequent in patients with vestibular peripheral vertigo. The duration of vertigo attack of vestibular central vertigo was longer(P<0.001). The onset of vestibular central vertigo was more related to body position(P<0.001). As compared with patients with vestibular peripheral vertigo, those with vestibular central vertigo demonstrated more abnormal in eye tracking test(40.6%vs 0.9%, P<0.001), calibration test(13.0%vs 0.0%, P<0.001), optokinetic test(10.1%vs 0.0%, P=0.003), gaze test(10.1%vs 0.0%, P=0.003), spontaneous nystagmus(8.7%vs 0.0%, P=0.007) or positional nystagmus(8.7%vs 0.0%, P=0.007). And positive positioning test was more common in patients with vestibular peripheral vertigo(14.5%vs 74.1%, P<0.001). Conclusion The features of VNG parameters are objective responses of nystagmus in vestibular vertigo patients. Combined with clinical features, they could help us distinguish vestibular central and peripheral vertigo.

    Full Text Available Objective: This retrospective study was conducted to determine the incidence of variouscomplications of Plasmodium vivax malaria based on review of case records.Methods: The case records of all confirmed cases of malaria over the period of one year (September2005–August 2006 were studied. Complete blood count, peripheral blood findings, liver and kidneyfunctions were reviewed. The results of rapid diagnostic test for malaria (OptiMAL test, DiamedAG, Switzerland were correlated with the peripheral blood smear findings in the patients in whomit was requested. All abnormal results like a positive direct Coomb’s test were noted. Findingswere clinically correlated.Results: There were 265 confirmed cases by peripheral blood examination. Of these 221 were dueto Plasmodium vivax and 41 due to P. falciparum. Two cases had mixed infection and in one casethe species could not be identified as it showed only malarial pigment. The peak incidence ofmalaria was seen in September 2005 and August 2006. The complications in P. vivax werethrombocytopenia, biochemical evidence of hepatic dysfunction, renal damage, positive DCT anddeath due to ARDS. Thrombocytopenia was seen in 213 patients with counts 3 mg/dl with normal liver enzymes. Liver enzymeswere elevated in 60 patients with seven patients showing liver enzymes level, three times the normal.Renal dysfunction was seen in 17 patients with serum creatinine ranging from 1.3–10.65 mg/dl.One patient went into acute renal failure following quinine therapy and showed red cell fragmentsin the peripheral blood. In two children DCT was positive with the peripheral smear showing RBCagglutinates around the parasitised RBC. There were three maternal deaths at about 32 weeksgestation due to ARDS. The peripheral blood smear in these patients showed WBC agglutinates.Conclusion: This paper is presented to highlight that P. vivax malaria though considered to be abenign entity can also have a severe and complicated course

    To elucidate the prognosis of different types of benign astrocytomas and to ascertain whether patients with partially resected benign astrocytomas, or any subtype of these, would benefit from postoperative radiotherapy, we studied retrospectively material comprising 300 patients with benign...... astrocytomas treated in the period 1956 to 1991. The pilocytic type of astrocytoma was found to have an outstandingly good prognosis and should be regarded as a distinct nosological entity. For the non-pilocytic supratentorial astrocytomas, a multivariate regression analysis showed that age, tumour site...... time of patients with non-pilocytic supratentorial benign astrocytomas. The study emphasizes the necessity of a prospective combined multicenter analysis of the effect of radiation on benign astrocytomas....

    Endobronchial localizations of benign neoplasms are met with in 24.5 per cent of the cases. Right lung localizations are more frequent. More than half of them are broadly based (57.5 per cent). In most of the cases it is a matter of nonepithelial tumours of which a greater intensity is displayed by hamartomas /7/, vascular /4/ and neurogenic /3/ neoformations. The size of endobronchial tumours varies from 1 to 10 cm. Cases measuring 1-3 cm are the most numerous. Those of the "iceberg" type appear to be larger. The size per se has a relative importance for the clinical picture. Endobronchial tumours exhibit a clear cut clinical picture, and run a clinical course in three stages, determined by the degree of bronchial obturation and longstanding of the condition. The most common symptoms are coughing /80.7 per cent/, expectoration /50.0 per cent/, rales /57.6 per cent/, dullness /38.4 per cent/ and lacking respiration /38.4 per cent/. The nosological entity by itself is less conclusive for the clinical course. The X-ray data have orientation and by no means decisive significance for the diagnosis. The "crab pincers" sign in the bronchial lumen during bronchography has a definite importance. Bronchoscopy in conjunction with biopsy is a dependable method of preoperative diagnosing. It contributes greatly to the nosological diagnosis. Even nowadays, the diagnosis of endobronchial tumours is difficult. A rather exact diagnosis can be made intraoperatively, whereas the most accurate diagnosis is established only after histological study. The treatment of endobronchial benign neoplasms is operative. The number of medium /lobectomies/ and extensive /pulmonectomies/ pulmonary resections is considerable. In case of early diagnosis and intervention, sparing resection is the naturally indicated size of operation - mainly resection and plasty of the bronchi without lobectomy. The advantages of circular resection are substantial. Reconstructive operations of "clarinet" and

    The data mining technique is adopted to analyze characteristics and rules of acupoint and meridian selection of acupuncture-moxibustion for treatment of vertigo at different time periods in the ancient. The data is collected from literature regarding acupuncture-moxibustion from the pre-Qin period to the end of Qing Dynasty, so as to establish a clinical literature database of ancient acupuncture-moxibustion for treatment of vertigo. Data mining method is applied to analyze the commonly used meridians, acupoints and special acupoints in different dynasties, also possible rules are explored. Totally 82 pieces of prescription of acupuncture-moxibustion for treatment of vertigo are included. In the history the leading selection of acupoitns are Fengchi (GB 20), Hegu (LI 4), Shangxing (GV 23) and Jiexi (ST 41) while that of meridians are mainly three yang meridians of foot and the Governor Vessel, especially the acupoints on the Bladder Meridian of foot yangming had the highest utilization rate, accounting for 23.04%. The acupoint selection is characterized by special acupoint, accounting for 80.6%, among which the crossing points are the most common choice. Distal-proximal acupoints combination is the most frequent method. The results indicate that the ancient acupuncture-moxibustion for treatment of vertigo focused on acupoints in the yang meridians, and the specific acupoints play an essential role in prescription; also the principle of syndrome differentiation and selecting acupoints along the meridians could be seen.

    International Nuclear Information System (INIS)

    Gastrointestinal mesenchymal tumors are a group of tumors, which originate from the mesenchymal stem cells of the gastrointestinal tract. Gastric schwannoma is a very rare gastrointestinal mesenchymal tumor, which represents only 0.2% of all gastric tumors and 4% of all benign gastric neoplasms. We report a 55 years old lady who suffered from pain epigastrium, vomiting, occasionally with blood, loss of appetite and weight loss. Endoscopic examination showed a round submucosal tumor with a central ulceration along the greater curvature of the stomach. The pathological examination revealed a picture of spindle cell tumor. Immunohistochemical stain was strongly positive for S-100 protein stain, and non-reactive for CD34, CD117, consistent with benign nerve sheath tumor of stomach i.e. gastric schwannoma. (author)

    Full Text Available OBJECTIVE: In this study,we aim to investigate the perception of neurology’s scope as a branch of medicine using the examples of headaches and vertigo disorders while establishing a relationship with the sociodemographic characteristics of the paticipants in our region. METHODS: 303 patients and patient relatives in Malatya who consulted to family physicians and emergency departments were included in this study. After the giving an informed consent, they were given a questionnare that was administered either in the written form or orally, based on their literacy status. We operationally defined neurolgy awareness as the relationship between complaints of headache and vertigo and their perceived relevance to neurolgy. RESULTS: In our study, 40%(n=121 of the participants reported that they would go to a neurology outpatient clinic if they have a headache and 44,9%(n=136 of the participants reported the same for vertigo complaints. On the other hand, 60%(n=182 of the participants reported that they would go to departments other than neurology if have headache and 55,1%(n=167 if they have vertigo complaints. The rate of patients who actually consulted in a neurology outpatient clinic with a headache complaint was 28.8% (n=45 whereas the rate for those who consulted in departments other than neurology was 71.2% (n=111. The rate of patients who actually consulted in a neurology outpatient clinic with a vertigo complaint was 39.6% (n=36 whereas the rate for those who consulted in departments other than neurology while having vertigo complaints was 60.4% (n=55. The public’s knowledge of neurolgy and both headache and vertigo were more extensive in with higher educational level, urban upbringing, urban residential status and women in general. There was no significant statistical relationship between age and income level with public’s knowledge of Neurology. CONCLUSION: In this study, more than one third of the participants associated complaints

    The postural balance is a important aspect of assessment in vestibular rehabilitation therapy. As the computerized dynamic posturography, the foam posturo-graphy performed by using foam in posturography is a useful measurement tool for postural balance. Then, the reliability of foam posturography is critical in clinic. To our knowledge, there is no report about the test-retest reliability of foam posturography in the patients with ver-tigo in China. The foam posturography was taken on the patients with vertigo in stable state and repeated in 3 to 5 days. In the two assessments of test and retest, all subjects stood under 4 sensory conditions, such as firm surface with eyes open (T1), firm surface with eyes closed (T2), foam surface with eyes open (T3) and foam surface with eyes closed (T4) for 30 seconds respectively. The average sway velocity (SV) of center of pressure (COP) under feet of upright standing was recorded as research parameter. The results of patients with vertigo were compared with those of normal subjects. It demonstrated that all normal subjects did not fall in the two assessments. There were 10 of 34 patients with vertigo at least fell one time during the two assessments, and the SVs of these subjects did not taken the analysis of test-retest reliability. The results showed that: (1) The interclass correlation coefficients (ICC) of all 49 subjects including normal subjects and patients without falling were 0.887-0.973 according to the T1-T4 between two assessment. (2) The SVs between the normal subjects and patients were significantly differ-ent in the T2 (t=2.018, P=0.049) and T4 (t=3.905, P<0.001) in the first assessment and in the T4 (t= 3.715, P=0.001) in the second. And (3) the cases of falling between two assessments were not significant different (X2=0.073, P=0.787) in the patients with vertigo. It is concluded from this study that the foam posturography has high test-retest reliability to assess the postural bal-ance in the patients with

Methods:TCM understandings of etiology,pathogenesis and methods of TCM syndrome differentiation and treatment of vertigo were summarized. Results: Wind, fire, phlegm, deficiency and stasis were the common pathogenic factors of vertigo and the disease location was in brain. The diseased zang and fu-organs involved with the liver,spleen and kidney. Most pathogenesis mechanisms of vertigo were deficiency in root and ex-cess in superficial level. Yin deficiency of liver and kidney was the root, while the wind, fire, phlegm and stasis were the superficial pathogenesis. But it also had type of excess complicated with deficiency. Clinical treatment should make syndrome differentiation based on disease differentiation, pay more attention to the deficiency or excess of zang and fu-organs, and treat disease on the basis of syn-drome. Conclusion: TCM has noticeable curative effects on syndrome differentiating and treating vertigo.

    Whipple\\'s procedure is the treatment of choice for pancreatic and periampullary malignancies. Preoperative histological confirmation of malignancy is frequently unavailable and some patients will subsequently be found to have benign disease. Here, we review our experience with Whipple\\'s procedure for patients ultimately proven to have benign disease. The medical records of all patients who underwent Whipple\\'s procedure during a 15-year period (1987-2002) were reviewed; 112 patients underwent the procedure for suspected malignancy. In eight cases, the final histology was benign (7.1%). One additional patient was known to have benign disease at resection. The mean age was 50 years (range: 30-75). The major presenting features included jaundice (five), pain (two), gastric outlet obstruction (one), and recurrent gastrointestinal haemorrhage (one). Investigations included ultrasound (eight), computerised tomography (eight), endoscopic retrograde cholangiopancreatography (seven; of these, four patients had a stent inserted and three patients had sampling for cytology), and endoscopic ultrasound (two). The pathological diagnosis included benign biliary stricture (two), chronic pancreatitis (two), choledochal cyst (one), inflammatory pseudotumour (one), cystic duodenal wall dysplasia (one), duodenal angiodysplasia (one), and granular cell neoplasm (one). There was no operative mortality. Morbidity included intra-abdominal collection (one), anastomotic leak (one), liver abscess (one), and myocardial infarction (one). All patients remain alive and well at mean follow-up of 41 months. Despite recent advances in diagnostic imaging, 8% of the patients undergoing Whipple\\'s procedure had benign disease. A range of unusual pathological entities can mimic malignancy. Accurate preoperative histological diagnosis may have allowed a less radical operation to be performed. Endoscopic ultrasound-guided fine needle aspirate (EUS-FNA) may reduce the need for Whipple\\'s operation

  1. [Height-induced vertigo and its medical interpretation: Goethe and the Strassburger Münster].

    Science.gov (United States)

    Jagella, C

    2000-02-19

    An analysis combining medicine and literature challenges the methodology of both disciplines. This essay on the vertigo Goethe suffered on the tower of the Strasbourg Minster attempts to trace the vicissitudes of interpreting an emblem, like vertigo, burdened by cultural meaning and implications. Thus, Goethe's own report of this event 40 years after the fact, in his "Dichtung und Wahrheit", has to be related to another, hidden chronology of vertigo and fear in his account which, at first glance, conveys quite different implications. The first part of this paper refers to a medical interpretation of Goethe's dread of high places and his way of coping with it which, today, could be defined as a typical example of a behaviourist approach. In the second part, Goethe's vertigo is linked to psychoanalytic, literary, and historical reflections on the meanings of symptoms we connect today with medical terms like anxiety, phobia, and vertigo. Goethe's vertigo is shown as a complex problem--not only for himself but also for its interpreters: on the one hand, it tells its own story-within-a-story; on the other, it depends on the tools it was written with. Traditional approaches of medical history try to find symptoms and traces of diseases known to us today in literary texts, an approach which is as dubious as taking today's tools of medical analysis, such as psychoanalytic terms and concepts, to explain specific phenomena in literature without first carefully analysing these methods themselves, and only then subjecting the text to an analysis based on them. Nevertheless, this essay does not contest the justification of interpreting literary texts in the light of today's medical knowledge, but postulates that it should be clear which type of medical knowledge is applied. It is quite possible to read Goethe's account only as an old tale of acrophobia, but how will this help us? It seems more interesting to look at the link between the feeling of dizziness he experienced on

  2. Cholesterol and benign prostate disease.

    Science.gov (United States)

    Freeman, Michael R; Solomon, Keith R

    2011-01-01

    The origins of benign prostatic diseases, such as benign prostatic hyperplasia (BPH) and chronic prostatitis/chronic pelvic pain syndrome (CP/CPPS), are poorly understood. Patients suffering from benign prostatic symptoms report a substantially reduced quality of life, and the relationship between benign prostate conditions and prostate cancer is uncertain. Epidemiologic data for BPH and CP/CPPS are limited, however an apparent association between BPH symptoms and cardiovascular disease (CVD) has been consistently reported. The prostate synthesizes and stores large amounts of cholesterol and prostate tissues may be particularly sensitive to perturbations in cholesterol metabolism. Hypercholesterolemia, a major risk factor for CVD, is also a risk factor for BPH. Animal model and clinical trial findings suggest that agents that inhibit cholesterol absorption from the intestine, such as the class of compounds known as polyene macrolides, can reduce prostate gland size and improve lower urinary tract symptoms (LUTS). Observational studies indicate that cholesterol-lowering drugs reduce the risk of aggressive prostate cancer, while prostate cancer cell growth and survival pathways depend in part on cholesterol-sensitive biochemical mechanisms. Here we review the evidence that cholesterol metabolism plays a role in the incidence of benign prostate disease and we highlight possible therapeutic approaches based on this concept. PMID:21862201

    2006-07-07

    The coupling of energetic metallic multilayers (a.k.a. flash metal) with energetic sol-gel synthesis and processing is an entirely new approach to forming energetic devices for several DoD and DOE needs. They are also practical and commercially viable manufacturing techniques. Improved occupational safety and health, performance, reliability, reproducibility, and environmentally acceptable processing can be achieved using these methodologies and materials. The development and fielding of this technology will enhance mission readiness and reduce the costs, environmental risks and the necessity of resolving environmental concerns related to maintaining military readiness while simultaneously enhancing safety and health. Without sacrificing current performance, we will formulate new impact initiated device (IID) compositions to replace materials from the current composition that pose significant environmental, health, and safety problems associated with functions such as synthesis, material receipt, storage, handling, processing into the composition, reaction products from testing, and safe disposal. To do this, we will advance the use of nanocomposite preparation via the use of multilayer flash metal and sol-gel technologies and apply it to new small IIDs. This work will also serve to demonstrate that these technologies and resultant materials are relevant and practical to a variety of energetic needs of DoD and DOE. The goal will be to produce an IID whose composition is acceptable by OSHA, EPA, the Clean Air Act, Clean Water Act, Resource Recovery Act, etc. standards, without sacrificing current performance. The development of environmentally benign stab detonators and igniters will result in the removal of hazardous and toxic components associated with their manufacturing, handling, and use. This will lead to improved worker safety during manufacturing as well as reduced exposure of Service personnel during their storage and or use in operations. The

  5. Labyrinthine enhancement of Gd-MR in patients with sudden hearing loss and vertigo

    International Nuclear Information System (INIS)

    In the past, no definitive diagnostic study was available to assess causes of sudden-onset hearing loss and vertigo. Our observations have led to an interesting new finding: labyrinthine enhancement on Gd-enhanced MR imaging in four patients with sudden unilateral hearing loss and/or vertigo. MR findings were correlated with audiologic and vestibular studies. All patients were studied with T2-weighted axial images through the whole brain and with Gd-DTPA-enhanced, 3-mm, axial, T1-weighted images through the temporal bone. No labyrinthine enhancement was seen in 20 control patients referred for other clinical problems. Gd-MR imaging might be able to distinguish patients with retrocochlear lesions from those in whom the abnormal process is in the labyrinth or is intraaxial

Results: The cure rates and total effective rates of acumoxi group and control group were 70.00%, 95.00%, 31.58% and 92% respectively, with the cure rate of the acumoxi group being significantly higher than that of control group (P<0.05). After treatment, the mean velocity of blood flow of the vertebral artery and basal artery decreased significantly (P<0.05,0.01 ). Conclusion: Acupuncture of cervical plexus plus moxibustion is effective definitely in treatment of cervical vertigo and superior to that of control group.

    1992-01-01

    The concept of 'translation' has for long been central to Friel's art. His two latest 'translations' are The London Vertigo (1990), a version of Charles Macklin's The True-born Irishman (1761) and A Month in the Country (1992), a version of Turgenev's play. This essay offers a close analysis of Friel's latest drama, suggesting reasons for his attraction to the earlier plays, discussing the implications of the changes he has made to the original or earlier texts, and indicating ways in whic...

  10. Dizziness and fear of falling: A behavioural and physiological approach to Phobic Postural Vertigo

    OpenAIRE

    Holmberg, Johan

    2006-01-01

    Dizziness is a common problem and it often co-exists with anxiety. Level of anxiety is the best predictor of handicap for dizzy patients. There is diagnostic controversy and few treatment programs for such patients. These patients can be labeled as panic disorder with agoraphobia or by the concept of Phobic Postural Vertigo which is characterized by dizziness or imbalance in standing or walking despite normal clinical balance tests and avoidance behaviours. This thesis aimed to investigate th...

    Full Text Available Vertigo, dizziness and unsteadiness (VDU are common symptoms traditionally considered to result from different kinds of vestibular and non-vestibular dysfunctions. The epidemiology of each symptom and how they relate to each other and to migraine, agoraphobia, motion sickness susceptibility (MSS, vaso-vagal episodes (VVE and anxiety-depression (AD was the object of this population-based study in north-eastern France. A self-administered questionnaire was returned by 2987 adults (age span 18-86 years, 1471 women. The 1-year prevalence for vertigo was 48.3%, for unsteadiness 39.1% and for dizziness 35.6%. The three symptoms were correlated with each other, occurred mostly (69.4% in various combinations rather than in isolation, less than once per month, and 90% of episodes lasted ≤ 2 minutes. The three symptoms were similar in terms of female predominance, temporary profile of the episodes and their link to falls and nausea. Symptom episodes of >1 hour increase the risk of falls. VDU are much more common than the known prevalence of vestibular disorders. The number of drugs taken increase VDU even when controlling for age. Each VDU symptom was correlated with each co-morbidity in Chi2 tests. The data suggest that the three symptoms are more likely to represent a spectrum resulting from a range of similar — rather than from different, unrelated — mechanisms or disorders. Logistic regressions controlling for each vestibular symptom showed that vertigo correlated with each co-morbidity but dizziness and unsteadiness did not, suggesting that vertigo is certainly not a more specific symptom than the other two. A logistic regression using a composite score of VDU, controlling for each co-morbidity showed a correlation of VDU to migraine and VVE but not to MSS and not to agoraphobia in men, only in women.

    The characteristics of selection and matching acupoint and application rules of meridians in ancient acupuncture literature for vertigo were explored. The data were collected from literature regarding acupuncture for vertigo from the pre-Qin period to Qing dynasty and then database was established. Frequency statistics method and comparison of support degree were applied to analyze and explore application rules of acupoints and meridians, while association rules in data mining was used to extract combinations of acupoints. As a result, for treatment of vertigo, according to frequency of use and support degree, generally the most selected acupoints, in turn, were Fengchi (GB 20), Shangxing (GV 23), Yanggu (SI 5), Jiexi (ST 41), Zulinqi (GB 41) and Shenting (GV 24), etc.; the most methods for matching acupoint were combination of adjacent acupoints, combination of same-meridian acupoints, combination of the superior-inferior acupoints, combination of yang-meridian and yang-meridian acupoints and combination of child-mother meridians acupoints; the most selected meridians were bladder meridian of foot-taiyang, gallbladder meridian of foot-shaoyang and governor vessel. Compared between the ancient and modern literature, it was found out that the ancient and modern clinic has same points in selection of acupoint-meridian and matching acupoints methods. However, the use of Yanggu (SI 5), Jiexi (ST 41) and Feiyang (BL 58) as well as combination of child-mother meridians acupoints were less seen in modern clinic, which could provide new reference.

    Patients will experience a wide range of skin growths and changes over their lifetime. Family physicians should be able to distinguish potentially malignant from benign skin tumors. Most lesions can be diagnosed on the basis of history and clinical examination. Lesions that are suspicious for malignancy, those with changing characteristics, symptomatic lesions, and those that cause cosmetic problems may warrant medical therapy, a simple office procedure (e.g., excision, cryosurgery, laser ablation), or referral. Acrochordons are extremely common, small, and typically pedunculated benign neoplasms. Simple scissor or shave excision, electrodesiccation, or cryosurgery can be used for treatment. Sebaceous hyperplasia presents as asymptomatic, discrete, soft, pale yellow, shiny bumps on the forehead or cheeks, or near hair follicles. Except for cosmesis, they have no clinical significance. Lipomas are soft, flesh-colored nodules that are easily moveable under the overlying skin. Keratoacanthomas are rapidly growing, squamoproliferative benign tumors that resemble squamous cell carcinomas. Early simple excision is recommended. Pyogenic granuloma is a rapidly growing nodule that bleeds easily. Treatment includes laser ablation or shave excision with electrodesiccation of the base. Dermatofibromas are an idiopathic benign proliferation of fibroblasts. No treatment is required unless there is a change in size or color, bleeding, or irritation from trauma. Epidermal inclusion cysts can be treated by simple excision with removal of the cyst and cyst wall. Seborrheic keratoses and cherry angiomas generally do not require treatment. PMID:26447443

    1996-06-01

    A 28-year-old man presented with a histiocytic sarcoma of a very uncommon origin, as it had developed for several years like a benign cutaneous histiocytosis resembling generalized eruptive histiocytoma before becoming acute, with nodal and massive pulmonary involvement. Despite various chemotherapies, the patient died within 8 months. Skin biopsies showed histiocytic proliferation in the dermis and node biopsies showed histiocytic proliferation with a sinusoidal pattern. Immunohistochemical analysis, performed on paraffin-embedded sections, demonstrated strong labeling of tumoral cells for CD68 and moderate labeling for CD3 and CD4. CD30 labeling was negative. S-100 protein was positive on a Langerhans' cell reactive subpopulation. Electron microscopy confirmed the histiocytic nature of malignant cells and showed cytoplasmic inclusions such as regularly laminated bodies, dense bodies and pleomorphic inclusions. No Birbeck granules were seen. A gene rearrangement study of T-cell receptor gamma and immunoglobulin heavy chain genes showed a germline configuration. Histiocytic sarcoma is an extremely rare true histiocytic malignancy, the existence of which has been recently debated since it has often been mistaken in the past for large cell lymphomas. Such a deceptive onset as benign cutaneous histiocytosis has not been described in the literature to our knowledge. PMID:8793665

    International Nuclear Information System (INIS)

    Objective: To present clinicopathological analysis of benign tumours of the vulva. Patients and Methods: Thirty cases of benign tumours of vulva were studied during 2 years research period. Detailed history along with complete local and general physical examination followed by all necessary pre-operative investigations were carried out. Excision surgery was the treatment of choice in majority of cases while marsupialization was done for Bartholin's cyst. Histopathology of tumours specimen was also collected. Results: A total of 30 cases were studied. Twenty-two were cystic and 8 were solid tumours. Aggressive angiomyxoma was 10% of solid tumours and Bartholin's cyst was 46.6% of cystic tumours. Most of the patients were multipara and between 21-30 years of age. The main site of tumour was labium majus. Excision surgery for all cases and marsupialization for Bartholin's cyst was treatment of choice. Conclusion: Aggressive angiomyxoma is the commonest solid benign vulval tumour. It should be considered in the differential diagnosis of vulval mass in women of reproductive age. (author)

Methods: By motor surveyor of skull three-dimensional space, the changes in the reversal ability of the skull space before and after the treatments with manual manipulations were observed in 72 cases of the patients with vertigo due to proprioceptive disturbance of the neck. Besides, 51 cases of vertigo due to insufficient blood supply of the cervical artery and 138 normal adults were selected as the control group. Results:After the treatments with manual manipulations, the deviation degree of the skull space in the three motor axes were all obviously decreased in the proprioceptive group, more obviously in the flexing and extending direction. The deviation degree of the skull space was also decreased in the ischemic group in the flexing and extending direction. Conclusion: Manual manipulations have the instant function to improve the proprioceptive function of the neck, and the factor of the proprioceptive disturbance also exists in the clinical onset of vertigo in pattern of insufficient blood supply of the cervical artery.

    Lithium transition metal fluorides (Li3MF6; M = Fe, V) with cryolite structure are investigated as positive electrode materials for lithium-ion batteries. A novel sol-gel process with trifluoroacetic acid as fluorine source was used to synthesize monoclinic and orthorhombic Li3CrF6. A ball milling process with Li3CrF6, binder, and conductive agent was applied to form a Li3CrF6 composite, which was electrochemically characterized against lithium metal for the first time. The electrochemical properties of two different modifications are quite similar, with a reversible specific capacity of 111 mAhg-1 for monoclinic Li3CrF6 and 106 mAhg-1 for orthorhombic Li3CrF6 (1 eq. Li ≙ 143 mAhg-1). The electrochemically active redox couple CrIII/CrII was confirmed by X-ray photoelectron spectroscopy.

  10. Benign and malignant gastrointestinal stromal tumors: CT findings and pathology

    International Nuclear Information System (INIS)

    Objective: Through a study of CT findings and the corresponding pathology of gastrointestinal stromal tumors (GIST), to improve the differential diagnosis of benign and malignant GIST. Methods: CT was performed in 25 patients with GIST confirmed by pathohistology and the images were analyzed retrospectively. CT images were compared with the corresponding pathological results, in which the benign and the malignant CT features were concluded. Results In 6 cases of benign GIST, all lesions were oval-shaped and well-defined. 5 cases out of 6 were smaller than Scm in diameter. The CT value increased over 25HU during contrast-enhancement in 5 cases. And there was no central hemorrhage and necrosis or involvement of adjacent organs. In 12 cases of malignant GIST, all tumor's were oval-shaped or lobulated. 10 cases out of 12 were larger than 5 cm in diameter. CT value was elevated over 2$HU in 9 cases during contrast-enhancement. Central hemorrhage and necrosis were found in 7 cases. The involvement of adjacent organs or metastasis was revealed in 9 cases. 7 cases of low grade malignant GIST shared various CT findings with the malignant or benign GIST. The size, non-enhanced density, adjacent involvement, distal metastasis, central hemorrhage and necrosis between malignant tumor and benign tumor were statistically different (p<0.01), while no statistical difference was found in increased CT value during contrast-enhancement, positive rate of immuno-histochemistry, or cell type. Conclusion GIST is lack of clinical, pathological, and CT imaging characterizes, and final diagnosis should be made with immunohistochemistry. But CT reveals the details of GIST and involvement of adjacent organs, which plays an important role in differential diagnosis of benign or malignant GIST and post-operative follow-up. (authors)

  11. STEADFAST: Psychotherapeutic Intervention Improves Postural Strategy of Somatoform Vertigo and Dizziness

    2015-01-01

    Full Text Available Patients with somatoform vertigo and dizziness (SVD disorders often report instability of stance or gait and fear of falling. Posturographic measurements indeed indicated a pathological postural strategy. Our goal was to evaluate the effectiveness of a psychotherapeutic and psychoeducational short-term intervention (PTI using static posturography and psychometric examination. Seventeen SVD patients took part in the study. The effects of PTI on SVD were evaluated with quantitative static posturography. As primary endpoint a quotient characterizing the relation between horizontal and vertical sway was calculated (QH/V, reflecting the individual postural strategy. Results of static posturography were compared to those of age- and gender-matched healthy volunteers (n=28; baseline measurements were compared to results after PTI. The secondary endpoint was the participation-limiting consequences of SVD as measured by the Vertigo Handicap Questionnaire (VHQ. Compared to the healthy volunteers, the patients with SVD showed a postural strategy characterized by stiffening-up that resulted in a significantly reduced body sway quotient before PTI (patients: QH/V=0.31 versus controls: QH/V=0.38; p=0.022. After PTI the postural behavior normalized, and psychological distress was reduced. PTI therefore appears to modify pathological balance behaviour. The postural strategy of patients with SVD possibly results from anxious anticipatory cocontraction of the antigravity muscles.

    Directory of Open Access Journals (Sweden)

    Katie Davis, OD

    2015-09-01

    Full Text Available Background: In order to maintain balance, input from the vestibular, somatosensory, and visual systems must work together to allow the patient to perform comfortably and to exist in his or her world. Any imbalance leads to a multitude of symptoms, including vertigo or disequilibrium. This paper analyzes a case of a patient suffering from long-standing vertigo and self-reported debilitating visual dysfunction. Case Report: A 47-year-old female presented with complaints of long-standing dizziness, a feeling of sickness in busy areas like grocery stores, the inability to multitask (including the inability to walk and talk at the same time comfortably, motion sensitivity, and disorientation. Due to her symptoms, the patient was unable to work, drive, or interact in social situations. Visual analysis revealed convergence insufficiency, oculomotor dysfunction, visual-vestibular sensory mismatch, and anomalous spatial perception. Traumatic brain injury testing quantified the patient’s complaints. Completion of a vision therapy program, with an emphasis on dynamic techniques including procedures to rehabilitate accommodative, vergence, and oculomotor insufficiencies, allowed the patient to return to her activities of daily living. Conclusion: In order to assist in the rehabilitative process, optometrists and other medical professionals must be cognizant of the vital role the visual system plays in regulating balance. Vision therapy must be considered as a treatment option to allow the rehabilitation process to be effective.

    Patients with somatoform vertigo and dizziness (SVD) disorders often report instability of stance or gait and fear of falling. Posturographic measurements indeed indicated a pathological postural strategy. Our goal was to evaluate the effectiveness of a psychotherapeutic and psychoeducational short-term intervention (PTI) using static posturography and psychometric examination. Seventeen SVD patients took part in the study. The effects of PTI on SVD were evaluated with quantitative static posturography. As primary endpoint a quotient characterizing the relation between horizontal and vertical sway was calculated (Q H/V ), reflecting the individual postural strategy. Results of static posturography were compared to those of age- and gender-matched healthy volunteers (n = 28); baseline measurements were compared to results after PTI. The secondary endpoint was the participation-limiting consequences of SVD as measured by the Vertigo Handicap Questionnaire (VHQ). Compared to the healthy volunteers, the patients with SVD showed a postural strategy characterized by stiffening-up that resulted in a significantly reduced body sway quotient before PTI (patients: Q H/V = 0.31 versus controls: Q H/V = 0.38; p = 0.022). After PTI the postural behavior normalized, and psychological distress was reduced. PTI therefore appears to modify pathological balance behaviour. The postural strategy of patients with SVD possibly results from anxious anticipatory cocontraction of the antigravity muscles. PMID:26843786

    Full Text Available This article reviews some of the more common benign oral papules and nodules of oral mucosa with emphasis on their etiology, epidemiology, clinical presentation, histopathology, and treatment. These lesions include mucocele, traumatic fibroma, epulis, pyogenic granuloma, oral papilloma, oral warts, lymphangioma, hemangioma, lipoma, oral nevi and some soft tissue benign tumors. These benign lesions must be separated clinically and histologically from precancerous and malign neoplastic lesions. Accurate clinico-pathological diagnosis is mandatory to insure appropriate therapy.

    Full Text Available Background. Benign paroxysmal torticollis (BPT is an episodic functional disorder of unknown etiology, characterized by the periods of torticollic posturing of the head, that occurs in the early months of life in healthy children. Case report. We reported two patients with BPT. In the first patient the symptoms were observed at the age of day 20, and disappeared at the age of 3 years. There were 10 episodes, of which 2 were followed by vomiting, pallor, irritability and the abnormal trunk posture. In the second patient, a 12-month-old girl, BPT started from day 15. She had 4 episodes followed by vomiting in the first year. Both girls had the normal psychomotor development. All diagnostical tests were normal. Conclusion. The recognition of BPT, as well as its clinical course may help to avoid not only unnecessary tests and the treatment, but also the anxiety of the parents.

    2016-01-01

    Benign prostatic hyperplasia (BPH) and associated lower urinary tract symptoms (LUTS) commonly affect older men. Age-related changes associated with metabolic disturbances, changes in hormone balance, and chronic inflammation may cause BPH development. The diagnosis of BPH hinges on a thorough medical history and focused physical examination, with attention to other conditions that may be causing LUTS. Digital rectal examination and urinalysis should be performed. Other testing may be considered depending on presentation of symptoms, including prostate-specific antigen, serum creatinine, urine cytology, imaging, cystourethroscopy, post-void residual, and pressure-flow studies. Many medical and surgical treatment options exist. Surgery should be reserved for patients who either have failed medical management or have complications from BPH, such as recurrent urinary tract infections, refractory urinary retention, bladder stones, or renal insufficiency as a result of obstructive uropathy.

    Benign paroxysmal positional vertigo, vestibular neuronitis and Menière's disease cause most cases of acute vertigo. However, doctors must consider central neurological reasons to vertigo. If it is determined that a patient has oto-neurological vertigo, the next task is to determine whether the...... patient has a peripheral or a central cause of vertigo, if the condition is potentially lethal and if there is a need for acute radiological imaging and/or medical intervention. This review highlights the oto-neurological approach to the dizzy patient with particular focus on the patient's history...

  1. Facilitating a benign interpretation bias in a high socially anxious population.

    2007-07-01

    Previous research has shown that high socially anxious individuals lack the benign interpretation bias present in people without social anxiety. The tendency of high socially anxious people to generate more negative interpretations may lead to anticipated anxiety about future social situations. If so, developing a more benign interpretation bias could lead to a reduction in this anxiety. The current study showed that a benign interpretation bias could be facilitated (or 'trained') in a high socially anxious population. Participants in the benign training groups had repeated practice in accessing benign (positive or non-negative) interpretations of potentially threatening social scenarios. Participants in the control condition were presented with the same social scenarios but without their outcomes being specified. In a later recognition task, participants who received benign interpretation training generated more benign, and less negative, interpretations of new ambiguous social situations compared to the control group. Participants who received benign training also predicted that they would be significantly less anxious in a future social situation than those in the control group. Possible implications of the findings for therapeutic interventions in social phobia are discussed. PMID:17349970

  2. MRI appearances of benign uterine disease

    International Nuclear Information System (INIS)

    Benign uterine disease is a common entity affecting women of all ages. Ultrasound has historically been the predominant imaging method used in the evaluation of benign gynaecological disease, magnetic resonance imaging (MRI) being reserved for use in the staging of malignant uterine and cervical disease. MRI is now increasingly used in the diagnosis of benign uterine disease as well as a tool for problem-solving in cases of diagnostic dilemma. It allows detailed assessment of benign conditions, such as endometrial lesions, leiomyomas, and adenomyosis, and can be helpful in the stratification of patients to different treatment modalities, including surgical resection, uterine artery embolization, and medical therapies. In this article, we review the MRI findings in the common benign uterine diseases

    The effectiveness of antibody-based release-active preparations Impaza (antibodies to eNOS), Tenoten (antibodies to brain-specific protein S-100), Dietressa (antibodies to type 1 cannabinoid receptor), Brizantin (combined preparation, antibodies to brain-specific protein S-100 and type 1 cannabinoid receptor), and Divaza (combined preparation, antibodies to brain-specific protein S-100 and eNOS) in the prevention of vertigo was studied on the model of intermittent accumulation of Coriolis accelerations (ICCA). Modification of activity of vestibular receptors and signal systems by release-active preparations contributed to an increase in ICCA tolerance time. Combined preparation Impaza possessed the most significant antinaupathic properties. Brizantin was less potent in this respect. PMID:26608378

    International Nuclear Information System (INIS)

    Standard treatments for benign lymphoepitelial lesion of the parotid gland in patients infected with the human immunodeficiency virus (HIV) are unsatisfactory. Recently, low-dose radiotherapy has been proposed as a noninvasive treatment option. We describe a case of bilateral benign lymphoepitelial lesion parotid gland in a HIV-positive paint, treated by radiotherapy. Low-dose radiotherapy, appears as a alternative in the treatment for benign lymphoepitelial lesion in HIV-patients, and preliminary evaluations have indicated that this treatment is effective from both the clinical and cosmetic points of view

    Full Text Available Background/Aim. Nocturia often occurs in patients with benign prostate hyperplasia (BPH. The aim of the study was to investigate the frequency of nocturia in patients with BPH. Nocturia and other factors associated with it were also investigated. Methods. Forty patients with the confirmed diagnosis of BPH were studied. Transurethral and transvesical prostatectomy were performed in all the patients. Symptoms were evaluated with the International Prostate Symptom Score before, as well as three and six months after the surgery. All the results were compared with the control group. Results. There was no statistically significant difference between the patients before and after the surgery regarding nocturia. There was, however, a statistically significant difference between the operated patients and the control group regarding nocturia, as well as a statistically significant correlation between noctruia and the age of the patients in both the investigated and the control group. A correlation also existed between nocturia and the prostatic size. Conclusion. There was no statistically significant improvement in symptoms of nocturia after the surgery. It is necessary to be very careful in decision making in patients with nonabsolute indiction for surgery and isolated bothersome symptom of nocturia. Age of a patient should also be considered in the evaluation of favorable result of the surgery because of a significant correlation between noctura and the age of a patient.

  6. Gallium scanning in differentiating malignant from benign asbestos-related pleural disease

    International Nuclear Information System (INIS)

    In order to assess the utility of 67gallium citrate in delineating malignant pleural mesothelioma from benign asbestos-related pleural disease, 49 patients with malignant mesothelioma and 16 with benign asbestos-related pleural disease were studied. Seven patients with malignant mesothelioma had no history of asbestos exposure, while the remaining 58 patients were exposed. Forty-three of the 49 patients (88%) with malignant mesothelioma had a positive 67gallium scan including 36 of the 42 (86%) patients with asbestos exposure and all 7 patients without a history of asbestos exposure. Three of 16 patients (19%) with benign asbestos-related pleural disease had a positive scan. 67Gallium radionuclide imaging is nonspecific but may be valuable in noninvasive monitoring of asbestos-exposed populations, which have a high risk for the late development of benign and/or malignant pleural disease

  9. Smoking habit and benign breast disease

    International Nuclear Information System (INIS)

    The possible association between cigarette smoking and the risk of benign breast disease (BBD) was assessed in a case-control study conducted in Gdansk, Poland, between 1990 and 1994. The study compared 160 women with newly diagnosed BBD admitted to the Gdansk Cancer Outpatients Clinic and 160 controls, women from outpatients clinics at the Medical University of Gdansk. There was no convincing evidence of an association, either positive or negative, between various indicators of smoking habit (smoking status, number of cigarettes smoked per day, duration of smoking) and the risk of BBD. Slightly lower relative risk (RRs) of BBD in ex-smokers of 10 or more cigarettes per day (RR = 0.9; 95% confidence interval, CI: 0.4-2.2), and with duration of smoking >= (RR = 0.1-3.4), were also observed in current smokers (RR = 0.8; 95% CI: 0.4-1.5), and (RR = 0.8; 95% CI: 0.1-3.4), but these findings were not statistically significant.

  11. Asbestos-related benign pleural disease review

    International Nuclear Information System (INIS)

    Benign pleural disease is the commonest manifestation of asbestos exposure encountered by radiologists. Benign pleural thickening can appear as circumscribed parietal pleural plaques or as more diffuse thickening of the visceral pleura. Benign-asbestos induced pleural effusions are a significant and under-recognized manifestation of asbestos exposure with important sequelae, such as diffuse pleural thickening which may be associated with functional impairment and for which compensation may be sought. This review concentrates on the strengths and weaknesses of chest radiography and computed tomography for the detection and characterization of benign asbestos-related pleural disease and the relevance of imaging abnormalities to compensation and functional impairment.

  2. Benign fracture versus malignant vertebral body infiltration

    International Nuclear Information System (INIS)

    MR imaging capabilities in differentiating marrow signal alterations seen in benign vertebral body compression fractures from those of malignant vertebral infiltration were assessed. Thirty-six patients, including 15 with posttraumatic vertebral compression fractures of known age, and 21 with malignant bone lesions, were imaged with MR. MR spine imaging (1.5 T) was performed with routine spin-echo sequences as well as inversion recovery (STIR), gradient-echo scans (GRASS), and chemical shift images (selective saturation technique) to obtain fat and water scans. Fat/water images enhanced differentiation between benign and malignant signal alterations. In general, patients with malignancy showed abnormal diffuse low signal intensity on fat images and corresponding increased signal on water images. Benign compression fractures showed variable patterns of signal alteration on fat/water images depending on fracture age. Old fractures showed persistent fat signal. Only very acute traumatic fractures showed increased signal on water images

    Full Text Available Abstract Introduction We report the case of a patient with a benign multicystic peritoneal mesothelioma and describe its appearance on computed tomography scans and ultrasonography, in correlation with gross clinical and pathological findings. Case presentation A 72-year-old Caucasian woman presented to our emergency department with acute abdomen signs and symptoms. A clinical examination revealed a painful palpable mass in her left abdomen. Abdominal ultrasonography and computed tomography demonstrated the presence of a large cystic mass in her left upper abdomen, adjacent to her left hemidiaphragm. The lower border of the mass extended to the upper margin of her pelvis. A complete resection of the lesion was performed. Pathological analysis showed a benign multicystic peritoneal mesothelioma. Conclusions Benign multicystic peritoneal mesothelioma is a rare lesion with a non-specific appearance on imaging. Its diagnosis always requires pathological analysis.

  4. Pharmacological treatment of the benign prostatic hyperplasia

    International Nuclear Information System (INIS)

    Benign prostatic hyperplasia is a common disease in over 50 years-old men consisting in uncontrolled and benign growth of prostatic gland that leads to lower urinary tract symptoms. The etiology of benign prostatic hyperplasia is multifactoral involving the increased conversion of testosterone in dihydrotestosterone by the prostatic 5α-reductase action, which brought about events that encourage the prostate growth (static component) and the increase of the bladder and prostate smooth muscle tone (dynamic component) regulated by the aα1 -adrenoceptors (ADR). The pharmacological treatment of the benign prostatic hyperplasia includes the prostatic 5aα-reductase inhibitors, the aα1-adrenoreceptor blockers, their combined therapy and the phytotherapy. This paper was aimed at presenting the most relevant aspects of the pharmacology of drugs used for treating the benign prostatic hyperplasia, and providing elements to analyze their efficacy, safety and tolerability. To this end, a review was made of the different drugs for the treatment of this pathology and they were grouped according to their mechanism of action. Natural products were included as lipid extracts from Serenoa repens and Pygeum africanum as well as D-004, a lipid extract from Roystonea regia fruits, with proved beneficial effects on the main etiological factors of benign prostatic hyperplasia. D-004 is a prostatic 5a-reductase inhibitor, an aα1-adrenoceptor antagonist, aα 5-lipooxygenase inhibitor and has antioxidant action, all of which reveals a multifactoral mechanism. The results achieved till now indicate that D-004 is a safe and well-tolerated product

    Hysterectomy is one of the most common gynaecological surgical procedures performed but there appears to be a decline in the performance of this procedure in Ireland in recent times. We set out to establish the extent of the decline of hysterectomy and to explore possible explanations. Data for hysterectomy for benign disease from Ireland was obtained from the Hospital In-Patient Enquiry Scheme (HIPE) section of the Economic and Social Research Institute for the years 1999 to 2006. The total number of hysterectomies performed for benign disease showed a consistent decline during this time. There was a 36% reduction in the number of abdominal hysterectomy procedures performed.

    Due to the expanding use of diagnostic imaging, an increasing number of liver tumours are discovered. Benign tumours are very common; they rarely cause symptoms and often they do not require any treatment. However, because of differences in the natural history including risk of complications and...... malignant transformation exact diagnosis is important. Dedicated radiological examinations serve as important diagnostic tools reducing the need for biopsy. In this review we provide an update on the diagnosis and treatment of benign liver tumours adding to existing recommendations on hepatocellular...

    Objective:To analyze the value of thyroid nodule ultrasonic strain elastography quantitative analysis in judging benignancy or malignancy of nodules.Methods: Patients diagnosed with thyroid nodule and receiving ultrasonic strain elastography quantitative analysis in our hospital were selected for study and divided into benign group and malignant group according to fine needle biopsy or the pathological results after surgical resection; mean strain values of quantitative indicators, blue region area and disorder of ultrasonic strain elastography, expression levels of malignant biological molecules in nodule tissue as well as the contents of serum tumor markers were detected.Results:Mean strain value of malignant group was lower than that of benign group, blue region area and disorder were higher than those of benign group, and standard deviation, complexity, kurtosis, skewness, contrast, equality, consistency and correlation were without significant differences; mRNA contents ofFascin-1, S100A4, STAT3, TC-1, MUC1 andMUC15 in thyroid nodules as well as serum Midkine, Galectin-3, CEACAM1 and TFF3 contents of malignant group were significantly higher than those of benign group, negatively correlated with mean strain value and positively correlated with blue region area and disorder.Conclusions:Mean strain values of quantitative indicators, blue region area and disorder of thyroid nodule ultrasonic strain elastography can judge benign or malignant nodules and assess the malignant degree.

  8. Contribution of diffusion-weighted MR imaging for predicting benignity of complex adnexal masses

    International Nuclear Information System (INIS)

    The purpose of this study was to prospectively assess the contribution of diffusion-weighted MR imaging (DWI) for characterizing complex adnexal masses. Seventy-seven women (22-87 years old) with complex adnexal masses (30 benign and 47 malignant) underwent MR imaging including DWI before surgery. Conventional morphological MR imaging criteria were recorded in addition to b1,000 signal intensity and apparent diffusion coefficient (ADC) measurements of cystic and solid components. Positive likelihood ratios (PLR) were calculated for predicting benignity and malignancy. The most significant criteria for predicting benignity were low b1,000 signal intensity within the solid component (PLR = 10.9), low T2 signal intensity within the solid component (PLR = 5.7), absence of solid portion (PLR = 3.1), absence of ascites or peritoneal implants (PLR = 2.3) and absence of papillary projections (PLR = 2.3). ADC measurements did not contribute to differentiating benign from malignant adnexal masses. All masses that displayed simultaneously low signal intensity within the solid component on T2-weighted and on b1,000 diffusion-weighted images were benign. Alternatively, the presence of a solid component with intermediate T2 signal and high b1,000 signal intensity was associated with a PLR of 4.5 for a malignant adnexal tumour. DWI signal intensity is an accurate tool for predicting benignity of complex adnexal masses. (orig.)

  9. Differential Diagnosis between Benign and Malignant Bowel Lesions on Ultrasonogram and CT

    International Nuclear Information System (INIS)

    To evaluate the diagnostic criteria for differentiation between benign and malignant bowel wall lesions on ultrasonogram (US) and CT. We prospectively analyzed 55 bowel lesions on US and CT, including 29 cases of benign lesion and 26 cases of malignant lesion. The thickness and length of the lesions were measured and the bowel features were classified into four categories : a) obliteration of bowel wall layers, b) marginal irregularity, c)eccentric wall thickening, and d) heterogeneous perilesional fat changes. We analyzed the sensitivity, specificity, positive and negative predictive values of each criterion. The mean thickness of malignant bovel lesions was 1.77 / 1.84 cm on US/CT, and that of benign lesions was 0.71 / 0.80 cm on US/CT. There was statistically significant difference in thickness between benign and malignant lesions (P<.05). The statistical analysis of incremental study showed that the most sensitive and specific criteria for malignant lesions were more than 1.2cm in thickness and less than 5.0cm in length. Among feature criteria, bowel wall obliteration, irregular margin and eccentric contour were statistically and significantly different between benign and malignant lesions (P<.05). The most sensitive and specific feature criterion was the bowel wall obliteration. The most sensitive and specific criteria for differentiation between benign and malignant bowel lesions were thickness and obliteration of bowel wall layers. Particularly, US was useful for the detection of bowel wall layers

    Understanding particle dynamics in the 'Twilight Zone' is critical to prediction of the ocean's carbon cycle. As part of the VERTIGO (VERtical Transformations In the Global Ocean) project, this rarely sampled regime extending from the base of the euphotic layer to 1000 m, was characterized by double-paired day/night Multiple Unit Large Volume in-situ Filtration System (MULVFS) deployments and by {approx}100 high-frequency CTD/transmissometer/turbidity sensor profiles. VERTIGO studies lasting three weeks, contrasted oligotrophic station ALOHA (22.75{sup o}N 158{sup o}W), sampled in June-July 2004, with a biologically productive location (47{sup o}N 161{sup o}E) near station K2 in the Oyashio, occupied July-August 2005. Profiles of major and minor particulate components (C{sub org}, N, P, Ca, Si, Sr, Ba, Mn) in <1, 1-51, and >51 {micro}m size fractions, in-water optics, neutrally buoyant sediment trap (NBST) fluxes, and zooplankton data were intercompared. MULVFS total C{sub org} and C-Star particle beam attenuation coefficient (C{sub P}) were consistently related at both sites with a 27 {micro}M m{sup -1} conversion factor. 26 At K2, C{sub P} profiles further showed a multitude of transient spikes throughout the water column and spike abundance profiles closely paralleled the double peaked abundance profiles of zooplankton. Also at K2, copepods contributed {approx}40% and 10%, night and day, respectively to >51 {micro}m C{sub org} of MULVFS samples in the mixed layer, but few copepods were collected in deeper waters; however, non-swimming radiolarians were quantitatively sampled. A recent hypothesis regarding POC differences between pumps and bottles is examined in light of these results. Particulate >51 {micro}m C{sub org}, N, and P at both ALOHA and K2 showed strong attenuation with depth at both sites.

    AIM: To investigate the expressions of E-cadherin and calretinin in exfoliated cells of serous effusions and evaluate their values in distinguishing malignant effusions from benign ones.METHODS: Fresh serous effusion specimens werecentrifuged and exfoliated cells were collected. Cells were then processed with a standardized procedure, including paraformaldehyde fixation, BSA-PBS solution washing and smears preparation. E-cadherin and calretinin were detected by immunocytochemistry (ICC).RESULTS: In the exfoliated cells of serous effusions, most of carcinoma cells only expressed E-cadherin, and most of mesothelial cells only expressed calretinin, and benign cells (lymphocytes and granulocytes) did not express either of them. For E-cadherin, 85.7% (30/35) of malignant effusions and 8.1% (3/37) of benign fluids were ICC-positive (P<0.001).The sensitivity of E-cadherin ICC in the diagnosis of malignant effusions was 85.7%, specificity 91.9%, and diagnostic rate 88.9%. For calretinin, 94.6% (35/37) of benign effusions and 11.4% (4/35) of malignant effusions were ICC-positive (P<0.001). The sensitivity of calretinin ICC in the diagnosis of benign effusions was 94.6%,specificity 88.6%, and diagnostic rate 91.7%. For diagnosis of benign and malignant effusions by combining E-cadherin ICC and calretinin ICC, the specificities were up to 100%and 97.1%, respectively.CONCLUSION: E-cadherin ICC and calretinin ICC are sensitive and specific in differential diagnosis of benign and malignant serous effusion specimens and specificities are evidently improved when both markers are combined.

    The VERtical Transport In the Global Ocean (VERTIGO) study examined particle sources and fluxes through the ocean's 'twilight zone' (defined here as depths below the euphotic zone to 1000 m). Interdisciplinary process studies were conducted at contrasting sites off Hawaii (ALOHA) and in the NW Pacific (K2) during 3 week occupations in 2004 and 2005, respectively. We examine in this overview paper the contrasting physical, chemical and biological settings and how these conditions impact the source characteristics of the sinking material and the transport efficiency through the twilight zone. A major finding in VERTIGO is the considerably lower transfer efficiency (T{sub eff}) of particulate organic carbon (POC), POC flux 500/150 m, at ALOHA (20%) vs. K2 (50%). This efficiency is higher in the diatom-dominated setting at K2 where silica-rich particles dominate the flux at the end of a diatom bloom, and where zooplankton and their pellets are larger. At K2, the drawdown of macronutrients is used to assess export and suggests that shallow remineralization above our 150 m trap is significant, especially for N relative to Si. We explore here also surface export ratios (POC flux/primary production) and possible reasons why this ratio is higher at K2, especially during the first trap deployment. When we compare the 500 m fluxes to deep moored traps, both sites lose about half of the sinking POC by >4000 m, but this comparison is limited in that fluxes at depth may have both a local and distant component. Certainly, the greatest difference in particle flux attenuation is in the mesopelagic, and we highlight other VERTIGO papers that provide a more detailed examination of the particle sources, flux and processes that attenuate the flux of sinking particles. Ultimately, we contend that at least three types of processes need to be considered: heterotrophic degradation of sinking particles, zooplankton migration and surface feeding, and lateral sources of

    Background Benign prostate hyperplasia is one of the most common diseases affecting the health of the aging males. Watchful waiting is an acceptable management strategy for benign prostate hyperplasia in which the patient is monitored by the physician but receives no active intervention. The epidemiological data on this are lacking in China. Our study was designed to evaluate the changes of signs and symptoms of patients with benign prostate hyperplasia during management by watchful waiting in China.Methods One hundred and forty-five patients with benign prostate hyperplasia aged > 50 years were enrolled in management by watchful waiting. All the patients were visited every 6 months and were given an International Prostate Symptom Score and Quality of Life questionnaire to complete. They also had uroflowmetry and were assessed using ultrasonography to get the volume of prostate, transition zone and amount of residual urine. The Student's t test, the Chi-square test, and variance analysis were used in the statistical analysis.Results All patients were visited after 6 months, the mean volume of transitional zone was found to haveincreased by 1.6 ml (P<0.01), International Prostate Symptom Score was increased by 0.8 (P<0.01) and Quality of Life was increased by 0.2 (P<0.01), and there was no statistical change in other data. Among these patients,17.9% (26/145) visited again after 12 months when the data failed to show a statistically significant difference among the three groups (0, 6, and 12 months).Conclusions After one year's follow-up, the progression of benign prostate hyperplasia was slow and the clinical data did not undergo much change.

  19. Distinguishing benign from malignant gallbladder wall thickening using FDG-PET

    International Nuclear Information System (INIS)

    Because thickening of the gallbladder wall is observed not only in patients with gallbladder cancer but also in those with benign diseases such as chronic cholecystitis and gallbladder adenomyosis, it is difficult to distinguish between benign and malignant gallbladder wall thickening by conventional techniques of diagnostic imaging such as computed tomography (CT), magnetic resonance imaging (MRI), and abdominal ultrasonography (US). In the present study, we attempted to distinguish between benign and malignant gallbladder wall thickening by means of fluorine-18-fluorodeoxyglucose (FDG)-Positron emission tomography (PET). FDG-PET was performed in 12 patients with gallbladder wall thickening detected by CT or US, to determine whether it was benign or malignant. Emission scans were taken, beginning 45 minutes after intravenous administration of FDG, and standardized uptake value (SUV) was calculated as an indicator of glucose metabolism. Of the 12 patients, 4 showed positive uptake of FDG in the gallbladder wall. Of these 4 patients, 3 had gallbladder cancer. The remaining one, who had chronic cholecystitis, had false-positive findings. The other 8 patients had negative uptake of FDG in the gallbladder wall. Two of these 8 underwent surgical resection, which yielded a diagnosis of chronic cholecystitis. The other 6 patients exhibited no sign of gallbladder malignancy and have been followed without active treatment. FDG-PET appears able to distinguish between benign and malignant gallbladder wall thickening. (author)

    Vertigo is one of the most common clinical syndrome, and the incidence of the vertigo population is about 5% to 8%. It can be divided into peripheral vestibular vertigo (more than 70%), central vestibular vertigo and non-vestibular ver-tigo, of which the incidence of otolith is more than 1/3 of all vertigo, but currently because of the lack of modern clinicians vertigophilosophy, and even only a handful of central vertigo, especially the "cerebral ischemia, cervical spondylosis" cov-ered the vast majority of vertigo diagnosis, leading to serious misdiagnosis and more than tens of billions of medical expens-es swallowed each year, so there is an urgent need of the precisely medicalnormalization of vertigo in China. The vertigo classification, the cause and composition of peripheral vestibular vertigo, the progress of the precise medicalnormalization and its meaning were reviewed in this paper, and the annual June 9 was recommended as the"China Vertigo Day" and even"the WorldVertigo Day".%眩晕症是一种最为常见的临床综合征,人群眩晕发病率约为5%~8%,可分为前庭周围性眩晕(占70%以上)﹑前庭中枢性眩晕和非前庭性眩晕,耳石症的发病率约占所有眩晕症的1/3以上,而目前临床医生由于缺乏现代眩晕理念,将只占极少数的中枢性眩晕,尤其是将“脑缺血﹑颈椎病”等甚至覆盖了绝大多数的眩晕诊断,严重误诊误治并大量吞噬医疗经费每年超过数百亿元,中国迫切需要眩晕精准医疗的常态化,该研究对眩晕的分类﹑前庭行了综述,并建议将每年的6月9日定为“中国眩晕防治日”乃至“世界眩晕防治日”。

    A central question addressed by the VERTIGO (VERtical Transport In the Global Ocean) study was 'What controls the efficiency of particle export between the surface and subsurface ocean'? Here, we present data from sites at ALOHA (N Central Pacific Gyre) and K2 (NW subarctic Pacific) on phytoplankton processes, and relate them via a simple planktonic foodweb model, to subsurface particle export (150-500 m). Three key factors enable quantification of the surface-subsurface coupling: a sampling design to overcome the temporal lag and spatial displacement between surface and subsurface processes; data on the size-partitioning of Net Primary Production (NPP) and subsequent transformations prior to export; estimates of the ratio of algal- to faecal-mediated vertical export flux. At ALOHA, phytoplankton were characterized by low stocks, NPP, F{sub v}/F{sub m} (N-limited), and were dominated by picoplankton. The HNLC waters at K2 were characterized by both two-fold changes in NPP and floristic shifts (high to low proportion of diatoms) between deployment 1 and 2. Prediction of export exiting the euphotic zone was based on size-partitioning of NPP, a copepod-dominated foodweb and a ratio of 0.2 (ALOHA) and 0.1 (K2) for algal:faecal particle flux. Predicted export was 20-22 mg POC m{sup -2} d{sup -1} at ALOHA (i.e. 10-11% NPP (0-125 m); 1.1-1.2 x export flux at 150 m (E{sub 150}). At K2, export was 111 mg C m{sup -2} d{sup -1} (21% NPP (0-50 m); 1.8 x E{sub 150}) and 33 mg POC m{sup -2} d{sup -1} (11% NPP, 0-55 m); 1.4 x E{sub 150}) for deployments 1 and 2, respectively. This decrease in predicted export at K2 matches the observed trend for E{sub 150}. Also, the low attenuation of export flux from 60 to 150 m is consistent with that between 150 to 500 m. This strong surface-subsurface coupling suggests that phytoplankton productivity and floristics play a key role at K2 in setting export flux, and moreover that pelagic particle transformations by grazers strongly

    A central question addressed by the VERtical Transport In the Global Ocean (VERTIGO) study was 'What controls the efficiency of particle export between the surface and subsurface ocean'? Here, we present data from sites at ALOHA (N Central Pacific Gyre) and K2 (NW subarctic Pacific) on phytoplankton processes, and relate them via a simple planktonic foodweb model, to subsurface particle export (150-500 m). Three key factors enable quantification of the surface-subsurface coupling: a sampling design to overcome the temporal lag and spatial displacement between surface and subsurface processes; data on the size partitioning of net primary production (NPP) and subsequent transformations prior to export; estimates of the ratio of algal- to faecal-mediated vertical export flux. At ALOHA, phytoplankton were characterized by low stocks, NPP, Fv/ Fm (N-limited), and were dominated by picoplankton. The HNLC waters at K2 were characterized by both two-fold changes in NPP and floristic shifts (high to low proportion of diatoms) between deployment 1 and 2. Prediction of export exiting the euphotic zone was based on size partitioning of NPP, a copepod-dominated foodweb and a ratio of 0.2 (ALOHA) and 0.1 (K2) for algal:faecal particle flux. Predicted export was 20-22 mg POC m -2 d -1 at ALOHA (i.e. 10-11% NPP (0-125 m); 1.1-1.2×export flux at 150 m ( E150). At K2, export was 111 mg C m -2 d -1 (21% NPP (0-50 m); 1.8× E150) and 33 mg POC m -2 d -1 (11% NPP, 0-55 m); 1.4× E150) for deployments 1 and 2, respectively. This decrease in predicted export at K2 matches the observed trend for E150. Also, the low attenuation of export flux from 60 to 150 m is consistent with that between 150 and 500 m. This strong surface-subsurface coupling suggests that phytoplankton productivity and floristics play a key role at K2 in setting export flux, and moreover that pelagic particle transformations by grazers strongly influence to what extent sinking particles are further broken down in the

    AIM: To investigate the pathological characteristics and carcinogenesis mechanism of benign lymphoadenosis of oral mucosa (BLOM).METHODS: The expressions of Ki-67, CD34 and apoptosis were evaluated by immunohistochemical SP staining in 64 paraffin-embedded tissue samples. Of them, 9 were from BLOM with dysplasia, 15 from BLOM without dysplasia,15 from oral squamous cell carcinoma (OSCC), 15 from oral precancerosis, and 10 from normal tissues. Cell proliferation, apoptosis and angiogenesis of tissue samples were also analyzed.RESULTS: The expression of Ki-67 in BLOM with dysplasia,oral precancerosis and OSCC was significantly higher than in BLOM without dysplasia and normal mucosa. The microvascular density (MVD) in BLOM with and without dysplasia, oral precancerosis, and OSCC was significantly higher than in normal mucosa. Apoptosis in BLOM and oral precancerosis was significantly higher than in OSCC and normal mucosa.CONCLUSION: Benign lymphoadenosis of oral mucosa has potentialities of cancerization.

  9. Skeletal scintigraphy in benign and malignant disease

    International Nuclear Information System (INIS)

    This paper begins with a discussion of the technical factors in skeletal scintigraphy, including collimation, the use of three-phase bone scan, and single-photon emission computed tomography. Skeletal scintigraphy for benign conditions is commonly indicated for the patient presenting with pain (trauma, sports-related injury, posttraumatic pain syndrome, painful orthopedic prosthesis) and for the patient with abnormal laboratory test results (metabolic bone disease, Paget disease). For malignant conditions, the bone scan is useful in the evaluation of metastases in patients with extraosseous malignancies and primary bone tumors. The discussion addresses the various scan patterns seen in the more common tumors, such as prostate carcinoma, breast carcinoma, and lung carcinoma. Bone scintigraphy is an exquisitely sensitive modality. With some understanding of the techniques necessary for obtaining the optimal bone scan, and of the patterns that can be seen in various clinical conditions, the radiologist will find the bone scan a very specific tool for evaluating both benign and malignant diseases

  10. Radiotherapy in benign uterine bleeding disorders

    International Nuclear Information System (INIS)

    Radiotherapy was earlier a method of choice for treatment of benign bleeding disorders (metropathia), especially in woman of high surgical risk. During the period 1912 to 1977 933 women with benign bleeding disorders were treated at Radiumhemmet with intracavitary brachytherapy or external irradiation or a combination of both. The result with regard to cure of the uterine bleedings was good (48%). Hormonal withdrawal symptoms after treatment were noted in 45% of the patients. In the long term follow up an increased risk of cardiovascular death was found in women treated before menopause. Malignant tumours occurred in 107 cases versus 90.2 expected. The estimated ovarian dose of ionizing radiation varied from 3.5 Gy to 6.0 Gy for the three standard techniques. Two women gave birth to a healthy child 4 and 5 years after intracavitary radium treatment. The estimated absorbed dose to the ovaries in these two women were 1 Gy and 4 Gy, respectively

    Benign biliary strictures are being increasingly treated with endoscopic techniques. The benign nature of the stricture should be first confirmed in order to ensure appropriate therapy. Surgery has been the traditional treatment, but there is increasing desire for minimally invasive endoscopic therapy. At present, endoscopy has become the first line approach for the therapy of postliver transplant anastomotic strictures and distal (Bismuth Ⅰ and Ⅱ) post-operative strictures. Strictures related to chronic pancreatitis have proven more difficult to treat,and endoscopic therapy is reserved for patients who are not surgical candidates. The preferred endoscopic approach is aggressive treatment with gradual dilation of the stricture and insertion of multiple plastic stents. The use of uncovered self expandable metal stents should be discouraged due to poor long-term results. Treatment with covered metal stents or bioabsorbable stents warrants further evaluation. This area of therapeutic endoscopy provides an ongoing opportunity for fresh research and innovation.

    International Nuclear Information System (INIS)

    Desmoplastic infantile ganglioglioma is a rare intracranial tumour of childhood that involves the cerebral cortex and the leptomeninges. We report two patients with desmoplastic infantile gangliogliomas and multiple cerebrospinal metastases. To our knowledge, only two similar cases have been reported in the published literature. Pathologically, this rare intracranial tumour shows glial and ganglionic differentiation, accompanied by an extreme desmoplastic reaction. These are low-grade neoplasms that are questionably benign.

    Schwannoma is a myelin sheath tumor that can occur almost anywhere in the body. The most common locations are the central nervous system, extremities, neck, mediastinum and retroperitoneum. Benign schwannomas in the porta hepatis are extremely rare and radiologically are diagnosed as either enlarged lymph nodes or bowel masses, such as gastrointestinal stromal tumors. In this location they usually produce symptoms by compressing adjacent structures and often present with obstructive jaundice. The preoperative diagnosis can be extremely difficult

    Purpose: To evaluate long-term results of treatment of benign bile duct strictures. Materials and methods: From February 1994 to November 2005, 21 patients (9 men, 12 women) with median age of 50.6 years (range 27-77 years) were indicated to percutaneous treatment of benign bile duct stricture. Stricture of hepatic ducts junction resulting from thermic injury during laparoscopic cholecystectomy was indication for treatment in one patient, stricture of hepaticojejunostomy was indication for treatment in all other patients. Clinical symptoms (obstructive jaundice, anicteric cholestasis, cholangitis or biliary cirrhosis) have appeared from 3 months to 12 years after surgery. Results: Initial internal/external biliary drainage was successful in 20 patients out of 21. These 20 patients after successful initial drainage were treated by balloon dilatation and long-term internal/external drainage. Sixteen patients were symptoms free during the follow-up. The relapse of clinical symptoms has appeared in four patients 9, 12, 14 and 24 months after treatment. One year primary clinical success rate of treatment for benign bile duct stricture was 94%. Additional two patients are symptoms free after redilatation (15 and 45 months). One patient is still in treatment, one patient died during secondary treatment period without interrelation with biliary intervention. The secondary clinical success rate is 100%. Conclusion: Benign bile duct strictures of hepatic ducts junction or biliary-enteric anastomosis are difficult to treat surgically and endoscopically inaccessible. Percutaneous treatment by balloon dilatation and long-term internal/external drainage is feasible in the majority of these patients. It is minimally invasive, safe and effective.

    Benign metastasizing leiomyoma (BML) is a rare condition that occurs in all age groups and that is particularly prevalent among women of late childbearing age. All patients have a history of uterine leiomyoma and/or myomectomy, often associated with distant metastases from the uterus, which commonly occurs in the lung. We report the case of a 32-year-old young woman suffering from chest stuffiness, labored respiration and weakness after a myomectomy performed one month earlier. The chest CT showed a diffuse miliary shadow in both sides of her lungs, but serum tumor markers such as CA125, CA199, carcinoembryonic antigen (CEA), neuron specific enolase (NSE), and CYFRA21-1 were normal. The patient underwent a lung biopsy by thoracoscopic surgery after four weeks of anti-TB treatment; there were no significant changes in the chest CT. H&E staining showed that the tumor cells had characteristics of smooth muscle cell differentiation. Immunohistochemical staining showed a low tumor cell proliferation index, which indicated that the likelihood of a malignancy was not high. There was no expression of CD10, indicating a diagnosis of pulmonary benign metastasizing leiomyoma (PBML). Smooth muscle actin (SMA) and desmin as specific markers of smooth muscle and the estrogen receptor (ER) and progesterone receptor (PR) were all strongly positive, which is characteristic of PBML. The patient was given the anti-estrogen tamoxifen for 3 months. With no radiological evidence of disease development and further distant metastasis, the patient will continue to be followed.

    Benign metastasizing leiomyoma (BML) usually are situated in one organ, most often in lungs. BML patients typically have a history of uterine leiomyoma treated with hysterectomy, myomectomy or subtotal hysterectomy. The aim of the study was to present the case of a 53-year-old woman with triple location in the lungs, parametria and appendix. She had undergone a myomectomy 26 years earlier. In 2015, she was admitted to the surgical department because of abdominal pain, whereupon a cholecystectomy was performed. CT scans showed pelvic mass with pulmonary metastasis. Upon discharge the patient was referred to the Gynecology Clinic, where a laparotomy was performed. The intraoperative findings were: 1) uterus with multiple leiomyomas, 2) four tumors in the parametria, 3) tumor connected to the appendix. A subtotal hysterectomy, with a bilateral salpingo-oophorectomy, removal of the tumors from the parametria and appendectomy was performed. Pathology confirmed the diagnosis based on morphology and immunohistochemical staining (strongly positive for estrogen receptors and SMA, while Ki67 was very low, below 1%). Upon postoperative recovery, the patient was referred to the Thoracic Surgery Department. During the thoracotomy, multiple nodes, surrounded by lung parenchyma, were revealed. Wedge resection was performed, for localized pulmonary lesions, and sent for pathological examination. The final pathological diagnosis was benign metastasizing leiomyomatosis. In conclusion, the triple location of BML could possibly be a result of a parallel different metastasizing mechanism, although it is impossible to exclude one mechanism, which may be the cause of the metastases in three locations.

  20. Surgical therapy of benign pineal tumors

    International Nuclear Information System (INIS)

    Currently, there is no way that the author knows to satisfactorily distinguish the benign lesions from their malignant cousins without a shadow of doubt. This includes preoperative evaluation of the clinical history, biological markers in serum and CSF, CT scans with and without contrast in various projections including the horizontal, coronal and sagittal cuts, and arteriography. Because the author has personally encountered difficulty in precisely diagnosing these tumors at routine light microscopy, especially when fragments are small, he has a personal aversion to the technique of diagnosis which enlists the use of a stereotactically placed biopsy needle. The author feels that virtually all of the pineal tumors require surgical exposure and sufficient tissue removal to ensure an accurate histological diagnosis. With experience, the author believes the surgeon can tell as he exposes the posterior and lateral aspects of these tumors whether or not they are encapsulated and therefore potentially resectable. This anatomical variation may be identified prior to operative intervention by an arteriogram especially with injection of large quantities of dye into the carotid system. With the advent of the CUSA (Cavitron Lasersonics, Cooper Medical Device Corporation, Stamford, CT), the author has used this instrument with increased facility and benefit in the removal of benign relatively avascular tumors of the pineal region. This instrument is ideal in coring out the interior of the tumor while creating little displacement of the tumor capsule. Some of the benign tumors, especially the meningiomas may be partially or heavily calcified and this instrument exhibits particular usefulness in these cases

    Full Text Available Background: To study the relationship between age, symptoms, ultrasound findings, size and histological type of benign adnexal masses. Methods: Clinical records were retrieved of women who had surgical management for adnexal tumors in the study period, i.e. from January 2007 to December 2010 at Sri Manakula Vinayagar Medical College and Hospital, Puducherry. Results: There were 112 cases of ovarian tumors and tumor like lesions. 70.5% were diagnosed as ovarian tumors, 12.5% were functional cysts, 10.7% were paraovarian and paratubal cysts, 6.25% were hemorrhagic infarct where histopathology could not be reported. The age of the patient ranged from 11 to 70 years. Most of the patients (70.5% presented with abdominal pain either acute or chronic. Serous cystadenoma was the most common reported ovarian tumor (59.5% followed by mucinous cystadenoma (20% and mature cystic teratoma (14%. The cystic tumors were either functional cysts or benign tumors. Conclusions: The commonest tumor was surface epithelial tumor. Serous cystadenoma was the most common benign tumor. Serous and mucinous tumors occurred equally on both sides. The accuracy of preoperative ultrasound was higher in dermoid cysts followed by endometriotic cysts.

    The manufacturing of silicon devices--from polysilicon production, crystal growth, ingot slicing, wafer cleaning, device processing, to encapsulation--requires many steps that are energy intensive and use large amounts of water and toxic chemicals. In the past two years, the silicon integrated-circuit (IC) industry has initiated several programs to promote environmentally benign manufacturing, i.e., manufacturing practices that recover, recycle, and reuse materials resources with a minimal consumption of energy. Crystalline-silicon solar photovoltaic (PV) modules, which accounted for 87% of the worldwide module shipments in 1997, are large-area devices with many manufacturing steps similar to those used in the IC industry. Obviously, there are significant opportunities for the PV industry to implement more environmentally benign manufacturing approaches. Such approaches often have the potential for significant cost reduction by reducing energy use and/or the purchase volume of new chemicals and by cutting the amount of used chemicals that must be discarded. This paper will review recent accomplishments of the IC industry initiatives and discuss new processes for environmentally benign silicon solar-cell manufacturing.

    1987-06-15

    Eight benign and three malignant granular cell tumors were characterized by means of antibodies and antisera against keratin, desmin, epithelial membrane antigen, factor VIII-related protein, lysozyme, myelin basic protein, myoglobin, neurone-specific enolase, S 100 protein, myelin-associated protein (Leu 7), glial fibrillary acidic protein, vimentin, and neurofilament. All benign granular cell tumours showed positive staining of the tumor cells to antibodies against vimentin, S 100 protein, and neurone-specific enolase; myelin-associated protein (Leu 7), in contrast, was only detectable in a few tumor sections. Histogenetically the granular cells may be classified as Schwann's cells which lost their expression of laminin. The three malignant granular cell tumors showed a staining pattern significantly different from that of the benign tumours. Thus, only neurone-specific enolase was detectable in all the tumors, whereas S 100 protein and vimentin could not be demonstrated but in one and two, resp., out of three tumors. PMID:3303714

    This study focused on the differences between two, subtypes of envy known as "benign envy" and "malicious envy" as personality traits, and examined the effects of these traits on academic achievement. Two hundred fifty-one university students participated in the study. Both benign envy and malicious envy were found to be independent as also found in a previous study by Lange & Crusius (2015), and a high criterion-related validity was revealed by an association with characteristic variables such as dispositional envy and self-esteem. The students with higher levels of benign envy were found to set goals higher, and as a result achieved higher levels of academic performance. In contrast, no such effect was found for malicious envy. The importance of focusing more attention on the positive aspects of the emotion of envy is discussed. PMID:27476271

    2010-10-01

    Full Text Available Background: Cytokeratin s (CK are used for the fingerprinting of carcinomas in general. In breast tissue, the luminal epithelial cells express CK 8/18, CK 7 and CK 19, while basal/myoepithelial cells express CK 5/6, CK 14 and CK 17. Material and Methods: Immunohistochemical staining for cytokeratin 5/6 was applied on cell block sections of 23 cases of benign and 25 cases of malignant breast lesions using avidin biotin peroxidase technique. The distribution and intensity of staining was recorded and graded semiquantitatively. Result: All benign lesions showed positive immunoreaction, with the staining index varying from 6-9, except lactating adenoma. The malignant lesions comprised three cases of ductal carcinoma in situ (DCIS and 22 cases of infiltrating ductal carcinoma, not otherwise specified, IDC (NOS. None of the DCIS cases showed a positive immunoreaction. Among the IDC (NOS lesions, six cases of grade III breast carcinoma exhibited a positive immunohistochemical reaction, the staining index of which varied from 2-6. The staining reaction in the malignant lesions was only cytoplasmic and the intensity was significantly less than that of benign lesions. Conclusion: CK 5/6 expression breast carcinoma implies a ′basal like′ molecular phenotype and is associated with poor prognosis. This antibody is also used as a component of panels to differentiate benign and malignant breast lesions.

  11. Diagnostic yield and impact of MRI for acute ischaemic stroke in patients presenting with dizziness and vertigo

    International Nuclear Information System (INIS)

    Aim: To identify predictors of acute ischaemic stroke (AIS) and evaluate the diagnostic yield and impact of magnetic resonance imaging (MRI) in patients imaged for dizziness and vertigo. Materials and methods: Patients imaged using MRI, including diffusion-weighted imaging (DWI) with or without computed tomography (CT), for dizziness and vertigo over a 2-year period were identified retrospectively. MRI findings were categorised as “acute ischaemic stroke”, “significant”, or “non-significant”. We reviewed the medical records to identify presenting symptoms and signs, vascular risk factors, duration of symptoms, and pre- and post-MRI clinical management in patients with proven stroke. Results: One hundred and eighty-eight patients were included: 39 with vertebrobasilar AIS (20.7%), 32 (17%) with a significant but non-ischaemic abnormality, and 117 (62.2%) with a normal or non-related abnormality. The sensitivity of CT in diagnosing AIS was 9.52% (95% CI: 1.67–31.8%). Posterior inferior cerebellar artery (PICA) territory infarcts were the most common (38.5%). Patients with AIS were significantly more likely to be older than 50 years (p = 0.04), have a greater number of cardiovascular risk factors (p < 0.01), shorter duration of symptoms (p = 0.03), and at least one neurological sign (p = 0.02). DWI MRI had a diagnostic impact on 21.6% patients with stroke. Conclusion: MRI plays an important role in differentiating peripheral and central aetiology when this proves challenging clinically. Predictors of AIS were identified that aid patient selection for MRI, to increase the yield and impact of neuroimaging. -- Highlights: •CT has a low sensitivity for diagnosing stroke in patients with dizziness and vertigo. •The yield of MRI for stroke in patients with these symptoms in our study was 21%. •The diagnostic impact of MRI on the management of these patients was 22%. •Predictors of stroke to increase the yield of MRI in this clinical context are

    Full Text Available Background: A lump in the breast is a cause of great concern. High frequency high resolution ultrasonogram helps in its evaluation. With major advances in ultrasonographic technology during the past 20 years, ultrasonogram can now distinguish benign and malignant solid breast lumps. Knowledge of the specific benign and malignant ultrasonographic characteristics of breast lumps is imperative for accurate diagnosis and optimal patient management. Objective: To determine the validity of ultrasound in the assessment of palpable breast lump by detecting the sensitivity, specificity, accuracy, positive predictive value and negative predictive value of ultrasonogram in distinguishing benign and malignant breast lumps. Materials and Methods: This cross sectional study was done in the department of Radiology and Imaging of Bangabandhu Sheikh Mujib Medical University (BSMMU, Dhaka in collaboration with the department of Pathology of BSMMU for histopathological correlation during July 2008 to June 2009. A total of 100 patients who were clinically suspected of having breast lump were included in this study. Data on clinical presentation, ultrasonographic findings including histopathological reports were collected and documented in structured forms. Analysis was done using SPSS 13.0 version. Results: The study was done in 100 women of 18–70 years of age with mean age 41.46 ± 11.62 years.

    International Nuclear Information System (INIS)

    Radiation therapy of benign diseases represent a wide panel of indications. Some indications are clearly identified as treatment of arteriovenous malformations (AVM), hyperthyroid ophthalmopathy, postoperative heterotopic bone formations or keloid scars. Some indications are under evaluation as complications induced by neo-vessels of age-related macular degeneration or coronary restenosis after angioplasty. Some indications remain controversial with poor evidence of efficiency as treatment of bursitis, tendinitis or Dupuytren's disease. Some indications are now obsolete such as warts, or contra-indicated as treatment of infant and children. (authors)

    Removal of vertigo blue dye from batik textile wastewater was studied by adsorptionprocess onto activated carbon (AC) and coal bottom ash (CBA).The influence of experimental conditions (pH solution, dye concentration, and contact time) were studied on the both adsorbents. At equilibrium conditions, the data were fitted to Langmuir and Freundlich adsorption models. The maximum adsorption capacity calculated from the Langmuir model for carbon active was 6.29mg/g at pH that found to be considerably higher than that obtained for coal bottom ash 3.72mg/g pH 9. From Freundlich model, the maximum adsorption capacity is less for coal bottom ash (pH 9) than that for carbon active (pH4).

    Objective: The aim of our study was to investigate the value of choline in the discrimination of benign and malignant soft tissue and bone tumors. Materials and methods: The study group consisted of thirty subjects with bone or soft tissue tumors larger than 1.5 cm in diameter. The experiments were performed in a 1.5 T MR scanner. Coils were selected according to specific locations. A single-voxel MRS was performed for three different TE (time to echo) (31, 136, 272 ms). The volume of interest was positioned on the brightest enhancement. The presence of a cholin peak on at least 2 of these spectrums was considered as the marker of malignancy. The sensitivity, specificity and accuracy of the MRS in the detection and diagnosis of malignant lesions were calculated. The reproducibility of MRS and histopathological results were tested with kappa statistics. Results: Histopathologically, 18 (60%) of the lesions were classed as malignant whereas 12 (40%) were classed as benign. With MRS, 15 (50%) of these lesions were classed as malignant and 15 (50%) as benign. Two patients who were found spectroscopically to have malignant tumors were shown histopathologically to have benign types. Five patients with an MRS showing a benign type were classed with malignant types in histopathological examinations. MRS had a sensitivity rate of 72.2%, specificity of 83.3%, and an accuracy rate of 76.6% in detecting malignant bone and soft tissue tumors. The interrater reliability of both techniques had a kappa value of 0.533. Conclusions: MRS may help in the differentiation of benign and malignant soft tissue and bone tumors.

  4. Differentiation of benign and malignant solitary pulmonary nodules : value of contrast-enhanced dynamic MR imaging

    International Nuclear Information System (INIS)

    To evaluate the usefulness of contrast-enhanced dynamic MR imaging for differentiation of benign and malignant solitary pulmonary nodules (SPNs). Twenty-three patients with histologically or radiologically provened SPNs smaller than 40mm (14 benign, 9 malignant) underwent MR examination using the breath-hold fast multiplanar spoiled gradient echo (FMPSPGR) technique. Pre-enhancement MR examination was followed by serial scans obtained at one-minute intervals, beginning one-minute after the onset of bolus injection of paramagnetic contrast agent for a total of five scans. Signal intensities of SPNs were measured from pre- and post-contrast enhanced MR images and peak percentage increase in signal intensity (p%SI) was calculated. Mean percentage increase in signal intensity (m%SI) was also calculated and the time-m%SI curve was plotted. The enhancement patterns of SPNs were classified as homogeneous, peripheral rim-like, inhomogeneous, or no (or minimal) enhancement. We compared differences in p%SI, the pattern of the time-m%SI curve, and the pattern of enhancement between benign and malignant SPNs. On dynamic MR images, alignant SPNs (n=9) showed a significantly higher p%SI than benign SPNs (n=14) (malignant : mean 120.6, range 81.8-171.6; benign : mean 29.5, range 3.7-78.9)(p<0.0001). With 80 p%SI as the threshold for malignancy-positive, both sensitivity and specificity were 100%. The m%SI of malignant SPNs rapidly increased at one minute after enhancement and decreased gradually thereafter, whereas that of benign SPNs increased more slowly to form a plateau. Eighty-nine percent (8/9) of malignant SPNs showed homogeneous enhancement. In contrast, among benign SPNs, peripheral rim-like enhancement and no (or minimal) enhancement occurred in the same proportion of cases : 50%(7/14). The superb demonstration of different enhancement characteristics obtained using dynamic contrast-enhanced MR imaging is useful to discriminate malignant from benign SPNs

Silodosin, (--1-(3-hydroxypropyl-5-[(2R-2-({2-[2-(2,2,2trifluoroethoxy phenoxy]ethyl}aminopropyl]-2,3-dihydro-1H-indole-7- carboxamide, is a new α1A-AR selective antagonist. Silodosin is highly selective for the α1A-AR subtype, showing an affinity for the α1A-AR that is 583- and 55.5-fold higher than its affinity for the α1B- and α1D-ARs, respectively. In randomized, double-blind, placebo-controlled phase III studies performed in Japan and the United States, silodosin has been shown to be effective for both storage and voiding symptoms associated with benign prostatic hyperplasia. Early effects of silodosin (after 2–6 hours or day 1 on lower urinary tract symptoms have also been reported. In urodynamic studies, detrusor overactivity disappeared in 40% and improved in 35% of patients after administration. In pressure flow studies, the grade of obstruction on the International Continence Society nomogram showed improvement in 56% of patients. The rate of adverse events in the silodosin, tamsulosin and placebo groups was 88.6%, 82.3%, and 71.6%, respectively. The most common adverse event was (mostly mild abnormal ejaculation (28.1%. However, few patients (2.8% discontinued silodosin because of abnormal ejaculation. Orthostatic hypotension showed a similar incidence in the silodosin (2.6% and placebo (1.5% groups. In conclusion, silodosin improves detrusor overactivity and obstruction and thus may be effective for both storage and voiding

    2008-05-01

    In the last years an increase in thyroid nodules detection has been reported from several epidemiological studies. This trend is largely due to the routine use of diagnostic sonography procedures in clinical practice. Thyroid nodules, both palpable or not palpable, rarely turn out to be malignant. Fine-needle aspiration cytology (FNAc) plays a central role in establishing the nature of the nodule. Excluded the presence of malignant lesions, which are generally treated with surgery, physicians are faced with a variety of therapeutic options, and choosing the optimal approach can be a difficult task. These include a periodic follow-up alone without treatment, the iodine supplementation, the thyroid-hormone suppressive therapy, the radioiodine administration, the percutaneous ethanol injections, and the new technique of laser photocoagulation. In all cases, decisions on the management of benign thyroid nodules should always be based on clinical target and a careful analysis of benefits and risks to the patient. PMID:18581970

  10. The radiation therapy of benign diseases

    International Nuclear Information System (INIS)

    X-ray should only be applied when other forms of treatment of good-natured diseases do not provide equally good results. One should note that somatic lesion should be completely avoided and genetic lesion avoided to the greatest probability. One can distinguish according to ones aims between inflammation irradiation, pain irradiation, stimulation therapy and functional therapy. An indication for inflammation irradiation can be post-operative parotitis, furuncle in the face, mastitis puerperalis, panaritium ossale, recurrent sudoriparouns abscesses and repelling reactions after transplanting organs. Pain irradiation is indicated with degenerative diseases of the skeleton system. A further possible application is radiotherapy of hypotrophic processes and benign tumours. Functional radiotherapy is indicated with hyperendocrinism, neurovegetative disorders and allergies. (MG)

X radiation for ringworm, ankylosing spondylitis and post-partum mastitis are considered. Figures for leukemia are roughly comparable between radiotherapy groups and A-bomb survivors. Figures for the increased relative risk of breast cancer in spondylitis patients were in marked contrast to bomb survivors who received comparable doses, but compatible with the increase among women given x-rays for acute post-partum mastitis in the 1940's and 1950's.

    Recent trends in research have gained an orientation toward developing efficient strategies using innocuous reagents. The earlier reported transition-metal-catalyzed carbonylations involved either toxic carbon monoxide (CO) gas as carbonylating agent or functional-group-assisted ortho sp(2) C-H activation (i.e., ortho acylation) or carbonylation by activation of the carbonyl group (i.e., via the formation of enamines). Contradicting these methods, here we describe an environmentally benign process, [Pd]-catalyzed direct carbonylation starting from simple and commercially available iodo arenes and aldehydes, for the synthesis of a wide variety of ketones. Moreover, this method comprises direct coupling of iodoarenes with aldehydes without activation of the carbonyl and also without directing group assistance. Significantly, the strategy was successfully applied to the synthesis n-butylphthalide and pitofenone. PMID:27377566

  15. Benign meningiomas: primary treatment selection affects survival

    International Nuclear Information System (INIS)

    Purpose: To examine the effect of primary treatment selection on outcomes for benign intracranial meningiomas at the University of Florida. Methods and Materials: For 262 patients, the impact of age, Karnofsky performance status, pathologic features, tumor size, tumor location, and treatment modality on local control and cause-specific survival was analyzed (minimum potential follow-up, 2 years; median follow-up, 8.2 years). Extent of surgery was classified by Simpson grade. Treatment groups: surgery alone (n = 229), surgery and postoperative radiotherapy (RT) (n = 21), RT alone (n = 7), radiosurgery alone (n = 5). Survival analysis: Kaplan-Meier method with univariate and multivariate analysis. Results: At 15 years, local control was 76% after total excision (TE) and 87% after subtotal excision plus RT (SE+RT), both significantly better (p = 0.0001) than after SE alone (30%). Cause-specific survival at 15 years was reduced after treatment with SE alone (51%), compared with TE (88%) or SE+RT (86%) (p = 0.0003). Recurrence after primary treatment portended decreased survival, independent of initial treatment group or salvage treatment selection (p = 0.001). Atypical pathologic features predicted reduced 15-year local control (54 vs. 71%) and cause-specific survival rates (57 vs. 86%). Multivariate analysis for cause-specific survival revealed treatment group (SE vs. others; p = 0.0001), pathologic features (atypical vs. typical; p = 0.0056), and Karnofsky performance status (≥80 vs. <80; p = 0.0153) as significant variables. Conclusion: Benign meningiomas are well managed by TE or SE+RT. SE alone is inadequate therapy and adversely affects cause-specific survival. Atypical pathologic features predict a poorer outcome, suggesting possible benefit from more aggressive treatment. Because local recurrence portends lower survival rates, primary treatment choice is important

  18. Differentiation of malignant and benign pulmonary nodules with first-pass dual-input perfusion CT

    International Nuclear Information System (INIS)

    To assess diagnostic performance of dual-input CT perfusion for distinguishing malignant from benign solitary pulmonary nodules (SPNs). Fifty-six consecutive subjects with SPNs underwent contrast-enhanced 320-row multidetector dynamic volume CT. The dual-input maximum slope CT perfusion analysis was employed to calculate the pulmonary flow (PF), bronchial flow (BF), and perfusion index (PI,=PF/(PF+BF)). Differences in perfusion parameters between malignant and benign tumours were assessed with histopathological diagnosis as the gold standard. Diagnostic value of the perfusion parameters was calculated using the receiver-operating characteristic (ROC) curve analysis. Amongst 56 SPNs, statistically significant differences in all three perfusion parameters were revealed between malignant and benign tumours. The PI demonstrated the biggest difference between malignancy and benignancy: 0.30 ± 0.07 vs. 0.51 ± 0.13, P < 0.001. The area under the PI ROC curve was 0.92, the largest of the three perfusion parameters, producing a sensitivity of 0.95, specificity of 0.83, positive likelihood ratio (+LR) of 5.59, and negative likelihood ratio (-LR) of 0.06 in identifying malignancy. The PI derived from the dual-input maximum slope CT perfusion analysis is a valuable biomarker for identifying malignancy in SPNs. PI may be potentially useful for lung cancer treatment planning and forecasting the therapeutic effect of radiotherapy treatment. (orig.)

Aims: The aim is to investigate the correlation among bcl-2 and c-erbB-2 and the micronucleus (MN formation in patients with early breast cancer (BC. Materials and Methods: This study was conducted between May 2010 and December 2011. We analyzed the MN frequencies in 15 patients with invasive breast carcinoma (IBC, 13 patients with intraductal proliferative lesion (IDPL and 12 benign breast lesion (BBL. The sample consisted of 40 formalin-fixed, paraffin-embedded blocks of benign and malignant breast tissue. The specimens were evaluated for bcl-2 or c-erbB-2 immunoreactivity was semi-quantitatively evaluated in at least 1000 cells examined under the microscope at 40Χ magnification and recorded as the percentage of c-erbB-2 and bcl-2 positive tumor cells over the total number of cells examined in the same area. The percentage scores were subsequently categorized using the 5% cut-off point for positive staining. Results: The MN was significantly increased in IBC and in IDPL patients compared to BBL patients (3.82 ± 0.17 and 2.37 ± 0.52, respectively, vs. 1.61 ± 0.40, P < 0.001. On other hand, the MN frequencies in IBC patients were higher than those in IDPL patients (3.82 ± 0.17 vs. 2.37 ± 0.52, P < 0.01. c-erbB-2, had the highest record in IBC (60%, and the score was not observed in both IDPL and BBL: bcl-2 immunostaining was also assessed, the lowest recorded score was in IBC (46.66% and the highest in both BBL and IDPL (100%. Furthermore, there was a significantly difference in the mean MN frequency between c-erbB-2 positive IBC patients (4.06 ± 0.48 and c-erbB-2 negative IBC patients (3.44 ± 0.39 (P < 0.05. Conclusions: Our results suggest that increased chromosome / DNA instabilities may be associated with the pathogenesis of

    We evaluated the standard uptake value (SUV) of F-18 FDG at PET/CT for differentiation of benign from malignant tumor in primary musculoskeletal tumors. Forty-six tumors (11 benign and 12 malignant soft tissue tumors, 9 benign and 14 malignant bone tumors) were examined with F-18 FDG PET/CT (Discovery ST, GE) prior to tissue diagnosis. The maxSUV(maximum value of SUV) were calculated and compared between benign and malignant lesions. The lesion analysis was based on the transverse whole body image. The maxSUV with cutoff of 4.1 was used in distinguishing benign from malignant soft tissue tumor and 3.05 was used in bone tumor by ROC curve. There was a statistically significant difference in maxSUV between benign (n = 11; maxSUV 3.4 {+-} 3.2) and malignant (n = 12; maxSUV 14.8 {+-} 12.2) lesion in soft tissue tumor ({rho} = 0.001). Between benign bone tumor (n = 9; maxSUV 5.4 {+-} 4.0) and malignant bone tumor (n = 14; maxSUV 7.3 {+-} 3.2), there was not a significant difference in maxSUV. The sensitivity and specificity for differentiating malignant from benign soft tissue tumor was 83% and 91%, respectively. There were four false positive malignant bone tumor cases to include fibrous dysplasia, Langerhans-cell histiocytosis (n = 2) and osteoid osteoma. Also, one false positive case of malignant soft tissue tumor was nodular fasciitis. The maxSUV was useful for differentiation of benign from malignant lesion in primary soft tissue tumors. In bone tumor, the low maxSUV correlated well with benign lesions but high maxSUV did not always mean malignancy.

    Full Text Available OBJECTIVE: The main utility of 18-fluorodeoxyglucose positron emission tomography (FDG-PET lies in the staging of lung cancer. However, it can also be used to differentiate indeterminate pulmonary lesions, but its impact on the resection of benign lesions at surgery is unknown. The aim of this study was to compare the prevalence of benign lesions at thoracotomy carried out for suspected lung cancer, before and after the introduction of PET scanning in a large thoracic surgical centre. MATERIALS AND METHODS: We reviewed our prospectively recorded surgical database for all consecutive patients undergoing thoracotomy for suspected or proven lung cancer and compared the prevalence of benign lesions in 2 consecutive 2-year groups, before (group I and after (group II the introduction of FDG-PET scan respectively. RESULTS: Surgical resection was performed on 1233 patients during the study period. The prevalence of benign lesions at surgery in groups I and II was similar (44/626 and 41/607, both 7%, and also in group II between those who underwent FDG-PET scan and the remainder (21/301 and 20/306 respectively, both 7%. In group II, of the 21 patients with benign lesions, who underwent FDG-PET, 19 had a false positive scan (mean standardised uptake value 5.3 [range 2.6-12.7]. Of these, 13 and 4 patients respectively had non-diagnostic bronchoscopy and percutaneous transthoracic lung biopsy pre thoracotomy. There was no difference in the proportion of different benign lesions resected between group I and those with FDG-PET in group II. CONCLUSION: The introduction of FDG-PET scanning has not altered the proportion of patients undergoing thoracotomy for ultimately benign lesions, mainly due to the avidity for the isotope of some non-malignant lesions. Such false positive results need to be considered when patients with unconfirmed lung cancer are contemplated for surgical resection.

  8. MRI of vertebral compression fracture: benign versus metastasis

    International Nuclear Information System (INIS)

    The study was performed to evaluate differentiating features of spinal compression fractures between benign and metastatic lesions. We reviewed MR imaging in 52 patients (benign 38, metastasis 14) with vertebral compression fracture. Signal intensity of fracture and uninvolved areas, presence of contrast enhancement fragmentation, and paravertebral mass were analyzed retrospectively. Signal intensity of fracture site was variable in benign lesions, but low signal intensity on T1-weighted image and high on T2-weighted image were seen in all cases of metastasis. Signal intensity of uninvolved area was high on T1-weighted image and low on T2-weighted image in 84% of benign lesions. On the contrary, normal marrow signal intensity was not seen in the uninvolved areas of all metastatic fractures. Contrast enhancement were observed in all cases of benign and metastatic compression fractures. Fragmentation were seen in 1 case of metastasis (7%) and in 11 cases of benign lesions (29%). Paravertebral mass were seen in 5 cases of metastasis (36%) and in 7 cases of benign lesions (18%). Presence of normal marrow signal intensity in the uninvolved area of fracture site could be the most useful sign for differentiating benign causes from metastasis

    Fidelman, Nicholas

    2015-12-01

    Interventional radiologists are often consulted to help identify and treat biliary strictures that can result from a variety of benign etiologies. Mainstays of noninvasive imaging for benign biliary strictures include ultrasound, contrast-enhanced computed tomography and magnetic resonance imaging, magnetic resonance cholangiopancreatography, and computed tomography cholangiography. Endoscopic retrograde cholangiography is the invasive diagnostic procedure of choice, allowing both localization of a stricture and treatment. Percutaneous biliary interventions are reserved for patients who are not candidates for endoscopic retrograde cholangiography (eg, history of distal gastrectomy and biliary-enteric anastomosis to a jejunal roux limb). This review discusses the roles of percutaneous transhepatic cholangiography and biliary drainage in the diagnosis of benign biliary strictures. The methodology for crossing benign biliary strictures, approaches to balloon dilation, management of recalcitrant strictures (ie, large-bore biliary catheters and retrievable covered stents), and the expected outcomes and complications of percutaneous treatment of benign biliary strictures are also addressed.

    Previous studies have not showed consistent results for the level of expression of sodium/iodide symporter (NIS) in thyroid diseases, especially malignant tumor. We undertook this study to evaluate the distribution of NIS expression in malignant thyroid diseases and compare with that in benign thyoid disease. Total patients were 119 cases (Men 15, 48{+-}13 yrs). Total number of samples were 205 pieces. In malignant thyroid disease, there were 153 samples: 90 in papillary carcinoma, 4 in follicular carcinoma, 2 in medullary carcinoma and 57 in metastatic lymph node. In benign thyroid disease, there were 52 samples: 36 in goiter/cyst, 11 in thyroiditis and 5 in follicular adenoma. Using immunohistochemical methods, we probed 205 samples with monoclonal anti-NIS Ab. Grading of staining was scored as 0 (negative or absent), 1 (weakly positive), 2 (moderately positive) or 3 (strongly positive). Expression rate (ER) of NIS positivity in individual disease entity was expressed as percentage of total number divided by number in 2 plus 3 grade. ERs of malignant thyroid diseases were 63% in papillary carcinoma, 81% in metastatic lymph node, 71% in follicular carcinoma and 100% in medullary carcinoma. ERs of benign thyroid disease were 53% in goiter/cyst, 64% in thyroiditis and 40% in follicular adenoma. ER of benign thyroid deceases was higher than benign thyroid diseases (71% vs 54%). Grading of NIS expression in papillary carcinoma or goiter/cyst was heterogeneously distributed in considerable cases. Normal tissue also showed heterogeneous distribution or NIS expression, which was not correlated with that of primary lesion. In papillary thyroid carcinoma, distribution of NIS expression was heterogeneous and increased, and not different compared with that of benign thyroid disease.

    Full Text Available BackgroundBenign Prostatic Hyperplasia is a widely prevalent conditionaffecting elderly men throughout the world. With increasinglife expectancy, there has been a rise in the percentage ofelderly men and so for this disease across the globe. There islack of information about health seeking behaviour of patientswith Benign Prostatic Hyperplasia. Therefore the study wasdesigned with the objectives of assessing health-seekingbehaviour and the effect of literacy on it among adult andolder subjects suffering from Benign Prostatic Hyperplasiaattending a tertiary care hospital.MethodA series of 81 patients suffering from Benign ProstaticHyperplasia above the age of 50 years, attending surgical OutPatient Department of a tertiary care hospital in Delhi, wereassessed for their health seeking behaviour using a pre-testedand a modified questionnaire designed for assessing healthseeking behaviour.ResultsPositive health seeking behaviour of patients was observed in44%, who reported to a doctor within a month of noticingtheir problem. A greater proportion of the literates was awareabout the symptoms suggestive of enlarged prostate andconsulted a qualified health care practitioner as their firstaction. More literates approached the higher level of healthcare facility on being referred and had maximum faith inallopathic system of medicine. Also, lesser number of literateshad performed pooja (Hindi word for worship or othertraditional rituals for relief of their problems.ConclusionWe concluded that majority of subjects suffering fromBenign Prostatic Hypertrophy were not aware of theirdisease and their health-seeking behaviour was poor andcould be related to literacy. Our data highlights the needfor public awareness program targeting the younger malepopulation so that early detection and treatment can beoffered.

    The purpose of this study was (1) to describe the thin section helical CT findings of hilar cholangiocarcinoma and of benign strcture, and to discuss the differential points between the two disease entities and (2) using cholangiographic correlation, to evaluate the diagnostic accuracy of helical CT in determining the extent of hilar cholangiocarcinoma. Twenty-seven patients with hilar cholangiocarcinoma and eight with benign biliary dilatation were studied. All except four with hilar cholangiocarcinoma, who underwentCT using a conventional scanner, were studied with two-phase helical CT. In all patients, cholangiographs were obtained by digital fluoroscopy after the injection of contrast materials into PTBD catheters. The level of obstruction was classified according to Bismuth, and 35 CT scans were studied blindly and retrospectively by two radiologists. The findings were analyzed for the presence of tumor, and then divided into two groups(cholangiocarcinomas and benign strictures), and the positive predictive value was calculated. The CT images of klatskin tumor were analyzed with special emphasis on the level and shape of the hilar obstruction. The level of biliary obstruction and extent of the tumor were carefully correlated with the results of cholangiography. Thin-section spiral CT correctly identified all tumor mass as a focal wall thickening obliterating the lumen. On arterial/portal phase CT scanning, 81% of infilterative tumors showed high attenuation. In all patients, differentiation between benign stricture and klaskin tumor was possible;correct identification of the level of obstruction and extent of tumor, according to Bismuth's classification, was possible in 63% of cases. For correct diagnosis of hilar cholangiocarcinoma and differentiation of benign stricture, helical CT was highly accurate and effective. Because of limital Z-axis resolution, however, the exact intraductal extent of the tumor was less accorately diagnosed.=20.

  17. Transurethral microwave thermotherapy for benign prostatic hyperplasia

    Directory of Open Access Journals (Sweden)

    Rubeinstein Jonathan N.

    2003-01-01

    Full Text Available Transurethral resection of the prostate (TURP remains the gold standard for treatment of benign prostatic hyperplasia (BPH. In general, while this procedure is safe, patients require a spinal, epidural, or general anesthesia and often several days of hospital stay; the potential morbidity and mortality limits the use of TURP in high-risk patients. Pharmacotherapy has been recommended as a first-line therapy for all patients with mild to moderate symptoms. Patients are oftentimes enthusiastic if they are offered a one-time method to treat lower urinary tract symptoms secondary to BPH, provided that the method offers reduced risk and allows an efficacy equal to that of medical therapy. One such method is transurethral microwave thermotherapy (TUMT. TUMT involves the insertion of a specially designed urinary catheter with a microwave antenna, which heats the prostate and destroys hyperplastic prostate tissue. TUMT allows the avoidance of general or regional anesthesia, and results in minimal blood loss and fluid absorption. In this review, the authors discussed the current indications and outcome of TUMT, including the history of the procedure, the mechanism of action, the indications for TUMT, the pre-operative considerations, the patient selection, the results in terms of efficacy, by comparing TUMT vs. Sham, TUMT vs. Alpha-blocker and TUMT vs. TURP. Finally, the complications are presented, as well as other uses and future directions of the procedure. The authors concluded that TUMT is a safe and effective minimally invasive alternative to treatment of symptomatic BPH.

    The incidence of common bile duct (CBD) pathology in a group of patients with benign biliary disease (n = 505) was found to be 23.2 per cent. The spectrum included 111 patients (90.2 per cent) with CBD stones, 37 of whom (33.3 per cent) had no symptoms or findings pre-operatively indicating CBD involvement. Five patients had papillary stenosis, three had postoperative CBD strictures, one had a choledochal cyst and one had an external biliary fistula. Of the 100 CBDs measuring more than 10 mm in diameter, 90 harboured calculi. In the remaining 23 CBDs measuring less than 10 mm, calculi were present in 21. The presence of CBD calculi was demonstrated by intra-operative cholangiography in 49 patients. In the remaining patients (n = 74), the diagnosis of CBD pathology was made either by percutaneous transhepatic cholangiography, endoscopic retrograde cholangio-pancreatography, T-tube cholangiography or peroperative palpation. The surgical procedures performed included choledochotomy and T-tube drainage (n = 74), transduodenal sphincteroplasty (n = 27) and choledochoduodenostomy (n = 18). The overall mortality and morbidity of CBD exploration was 3.3 per cent and 24.4 per cent respectively, which was significantly greater than that for cholecystectomy alone (0.3 per cent and 8.6 per cent respectively). Transduodenal sphincteroplasty carried a much higher mortality (11 per cent) and morbidity (52 per cent) when compared with other procedures. PMID:3167536

  19. Benign and pathological electrocardiographic changes in athletes.

    2015-12-01

    Sudden cardiac death is the leading cause of death in athletes during sport. It is a tragic event that generates significant media attention and discussion throughout society as to whether everything possible had been done to prevent it. Regular physical exercise causes cardiac remodeling at both the mechanical and electrical level, known as athlete's heart, resulting in an electrocardiogram (ECG) considered abnormal compared with the ECGs of the general population. Some of these electrocardiographic changes are considered normal or physiological in athletes, while others suggest underlying cardiac disease with the potential to cause sudden cardiac death. There is thus an urgent need to define the electrocardiographic patterns that allow or prohibit participation in sports, and to differentiate them in terms of gender, ethnicity and age. The purpose of this review is to present the latest data on the electrocardiographic changes considered benign or pathological that are typically found in athletes and to critically analyze the most recent criteria for classifying ECGs in this population (the Seattle criteria), comparing them with previous guidelines and with the latest studies on the subject. This article also examines the question of including ECGs in pre-participation screening programs, the US and European approaches to the subject, and the most up-to-date data on the sensitivity, specificity and cost-effectiveness of the ECG in athletes.

    2016-01-01

    The pharmacological treatment of benign prostatic hyperplasia (BPH) is indicated when men suffer from lower urinary tract symptoms (LUTS) but there are no absolute indications for prostate surgery or severe bladder outlet obstruction. Phytotherapy can be used in men with mild to moderate LUTS and alpha-blockers can quickly and effectively decrease the LUTS and symptomatic disease progression. Phosphodiesterase type 5 inhibitors (PDE5-I) are an alternative to alpha-blockers when men experience bothersome side effects from alpha-blockers or erectile dysfunction. If patients predominantly have bladder storage symptoms and a small prostate, muscarinic receptor antagonists are a viable treatment option. The combination of alpha-blocker plus muscarinic receptor antagonist is more efficacious in reducing LUTS than the single drugs alone. The 5 alpha-reductase inhibitors (5ARI) can significantly decrease LUTS and disease progression (e.g. acute urinary retention and need for prostate surgery) in men with larger prostates (> 30-40 ml). The combination of 5ARI plus alpha-blocker can reduce LUTS and disease progression more effectively than drug monotherapy. Combination therapy with PDE5-I (tadalafil) plus 5ARI (finasteride) reduces LUTS more substantially than 5ARI alone and, additionally, PDE5-Is reduce the sexual side effects during 5ARI treatment.

  1. Balloon catheter dilatation of benign urethral strictures

    International Nuclear Information System (INIS)

    The authors report their experience of benign urethral stricture dilatation by balloon catheter in 11 male patients. Ten posterior and 2 anterior urethral strictures were treated; in 1 patients several narrowings coexisted at various levels. Etiology was inflammatory in 4 cases, iatrogen in 3, post-traumatic in 2, and equivocal in 2. The patients were studied both before and soon after dilatation by means of retrograde and voiding cystourethrogram and uroflowgraphy; the follow-up (2-14 months) was performed by urodynamic alone. In all cases, dilatation was followed by the restoration of urethral gauge, together with prompt functional improvement of urodynamic parameters. The latter result subsisted in time in 9 patients. In 2 cases recurrences were observed demonstrated at once by clinics and urodynamics. Both lesions were successfully re-treated. Neither early not late complication occurred. In spite of the limited material, the valuable results obtained, together with the absence of complications, the peculiar morphology of recurrences, and the chance of repeating it make the procedure advisable as a valid alternative to conventional techniques for these pathologies

  2. Visual laser coagulation for benign prostatic hyperplasia

    International Nuclear Information System (INIS)

    A total of 28 patients with symptomatic bladder outlet obstruction due to benign prostatic hyperplasia were treated by visual laser coagulation (VLAP) performed with the Myriadlase side-firing neodymium: YAG laser fibre at 40 watts power. The treatment was performed as an outpatient procedure using intraurethral gel anaesthesia and light intravenous sedation and analgesia. Prostatic volume was 32 g and 650 joule per gram prostatic tissue was administered. The patients were evaluated at mean 9.2 weeks. The mean operative time was 34 minutes. The procedure was very gentle, all patients tolerated it well and there was no bleeding. Most patients experienced some dysuria for three to four weeks after the procedure, two had severe symptoms. Two patients remained in retention and required transurethral resection. The rest expressed subjective satisfaction with the results. Peak urinary flow increased from mean 9.0 ml/sec preoperatively to 15.4 ml/sec; a mean increase of 78%. One patients developed clinical urinary tract infection. There were no other complications of clinical significance. 19 refs., 1 fig

  3. Perspectives of radiation therapy in benign diseases

    International Nuclear Information System (INIS)

    Purpose: the numbers of patients with nonmalignant diseases referred for radiation therapy had to be evaluated for the last 4 years. Patients and methods: in the years 2002, 2004, and 2005 radiation therapy was performed in 61, 40, and 26 patients, respectively. Regularly, more women than men were treated, median age annually was 57, 54, and 55 years, respectively (table 1). The radiotherapy scheme was not modified within the evaluated period. Results: the proportion of nonmalignant diseases among all patients treated decreased from 4.7% in 2002 to 3.3% in 2004 and 2.2% in 2005, respectively. A shift was noticed toward the treatment of four main diseases (endocrine orbitopathy, prevention of heterotopic ossification, meningeoma, tendinitis, table 2). The number of referring physicians decreased from 19 to six. Conclusion: due to administrative restrictions for treatment in hospitals, budget restrictions in private practices and lasting, insufficient revenues for radiotherapy in nonmalignant diseases, radiation therapy for the entire group of benign diseases is endangered.

    Benign subcutaneous lesions are a common reason that patients visit family physicians. Lipomas are the most common of these lesions; they most often occur on the trunk and proximal extremities. Recent data show that as many as half of the fat cells in lipomas are atypical. Ultrasound is used increasingly to confirm lipoma diagnosis, but deep lesions should be evaluated with magnetic resonance imaging study or computed tomography scan to exclude involvement of underlying structures and/or liposarcoma. Small lesions can sometimes be managed with serial injections of midpotency steroids. Larger lesions (larger than 5 cm), those compressing other structures, or those suspicious for malignancy should be excised using standard surgical excision or, when possible, the newer minimal-scar segmental extraction technique. Ganglion cysts are another common lesion, the presence of which often is confirmed with ultrasound if the diagnosis is not clinically apparent. Management includes splinting, aspiration, and/or injection of steroids, with or without hyaluronidase. Epidermal inclusion cysts, also called sebaceous cysts, typically are asymptomatic unless they become infected. Ultrasound can aid in diagnosis. The only definitive management is surgical excision with complete removal of the cyst wall or capsule, using minimal-scar segmental extraction or conventional surgical removal. PMID:23600336

  6. Spontaneous rupture of intracranial dermoid tumor in a patient with vertigo. Computed tomography and magnetic resonance imaging findings

    International Nuclear Information System (INIS)

    Congenital dermoid cysts are very rare, constituting less than 1% of intracranial tumors. Spontaneous rupture of dermoid tumor is a potentially serious complication that can lead to meningitis, seizures, cerebral ischemia and hydrocephalus. Occasionally, dermoid tumors are incidentally discovered on computed tomography (CT) of the brain or magnetic resonance imaging (MRI) following unrelated clinical complaints. They are also discovered during radiologic investigations of unexplained headaches, seizures, and rarely olfactory delusions. In this report we describe a patient complaining of vertigo caused by spontaneous rupture of dermoid cyst, preoperatively diagnosed by CT and MRI. Cranial CT revealed a dense fatty lesion adjacent to the posterolateral parasellar region on the left with multiple small, dense fat droplets scattered in the subarachnoid space corresponding to a dermoid cyst rupture. Cranial MRI sections revealed a lesion with mixed-signal-intensity and multiple hyperintense droplets scattered through the cerebellar surface on the left. No enhancement was found on axial T1-weighted MRI after intravenous Gadolinium administration. Diffusion weighted image (DWI) and apparent diffusion coefficient map studies exhibited explicit restricted diffusion. Many studies and literature case reports concerning the rupture of dermoid cyst have been reported. However, multimodal imaging of this rare pathology in the same patient is uncommon. Although dermoid cysts are pathognomonic in appearance on a CT examination, the MRI is also of value in helping to understand the effect of extension and pressure of the mass. DWI is also important for support of the diagnosis and patient follow-up

    Full Text Available The articles presents a view of the pharmacological and nutritive therapy of the most frequent diseases of males, which are benign prostatic hyperplasia and chronic prostatitis. A modern man is in constant deficiency of various biologically active substances, with the lack of them in food and without generating of sufficient quantity of coenzymes and enzymes. In the author,s opinion, complex drugs that contain highquality biological extracts may provide the substances required for prevention and slowing down the progress of benign prostatic hyperplasia and chronic prostatitis to the male organism. Study of biological activity of food supplement Andro-PRO (Russia that contain the elements required for normalization of the functional state of the prostate was performed. Application of the drug favors positive dynamics of clinical symptoms of the studied nosological entities and has restorative effect on the function of the glandular tissue of the prostate. Analysis of modern references, primary results of clinical studies show the necessity of pharmacological and nutritive support of patients with asymptomatic progress of benign prostatic hyperplasia and chronic prostatitis with the drug. Application of drug studied is efficient and safe, which is confirmed with improvement of indicators and life quality assessment, positive clinical dynamics, and absence of side effects.

    We describe a case of cerebellar ataxia associated with anti-Hu antibodies and benign ganglioneuroma. A 28-year-old woman developed progressive ataxia with hyporeflexia at the age of 19. Brain MRI showed progressive cerebellar atrophy. Neurophysiological studies, screening of immune-mediated ataxias, oncological markers, vitamin E and genetic tests for spinocerebellar ataxia types 1,2,3, Friedreich ataxia and POLG1 were negative. Anti-Hu antibodies were positive in Western blot and indirect immunofluorescence (1:640). Total-body computed tomography revealed a mediastinum mass; the histological diagnosis was maturing ganglioneuroma. Immunohistochemistry showed a mild reaction between the tumor and the patient's serum, and no reaction between the tumor and control serum. After surgery, serum anti-Hu titer decreased, while ataxic symptoms initially worsened and then stabilized. Ganglioneuroma is a benign tumor, usually derived from the maturation of a neuroblastoma. The benign histology and the presence of anti-Hu antibodies could be related to the positive oncological prognosis and to the slow clinical course mimicking a degenerative ataxia. PMID:25764259

    Radiation therapy of benign diseases represent a wide panel of indications. Some indications are clearly identified as treatment of arteriovenous malformations (AVM), hyperthyroid ophthalmopathy, postoperative heterotopic bone formations or keloid scars. Some indications are under evaluation as complications induced by neo-vessels of age-related macular degeneration or coronary restenosis after angioplasty. Some indications remain controversial with poor evidence of efficiency as treatment of bursitis, tendinitis or Dupuytren`s disease. Some indications are now obsolete such as warts, or contra-indicated as treatment of infant and children. (authors)

    The most common pathologic conditions in the axilla are the diseases related to lymph nodes, of which the most serious condition is a malignant lesion such as the metastatic lymphadenopathy or lymphoma. However, various benign conditions in the axilla have been reported and some of them show characteristic imaging findings which allow presumptive diagnosis to be made without invasive procedures. We review various conditions of benign axillary mass and illustrate typical findings in this essay. Sonography can evaluate the axillary area easily and immediately performed sonography-guided core needle biopsy is also useful when the axillary mass does not have typical benign features

  12. Tadalafil: a phosphodiesterase-5 inhibitor for benign prostatic hyperplasia.

    2013-06-01

    Tadalafil is a phosphodiesterase (PDE)-5 inhibitor recently approved by the United States Food and Drug Administration for lower urinary tracts symptoms (LUTS) associated with benign prostatic hyperplasia (BPH). The mechanism for improved LUTS is thought to be related to three principal theories: alterations in nitric oxide levels, Rho-associated protein kinase deactivation, and reductions in pelvic atherosclerosis. The efficacy of PDE-5 inhibitors for the treatment of LUTS associated with BPH has been demonstrated in several randomized placebo-controlled trials. Tadalafil is thought to be superior based on an extended half-life; however, other PDE-5 inhibitors have positive results in BPH and have not been proved to be inferior to tadalafil. Before administration, concomitant use of medications such as nonselective α-adrenergic antagonists, nitrates, and cytochrome P450 inhibitors should be assessed for possible drug interactions. Potential adverse drug events seen in Food and Drug Administration-approved tadalafil include back pain, dyspepsia, headache, and dizziness. Given the efficacy and safety data currently available, the PDE-5 inhibitor tadalafil represents a reasonable alternative for selected male patients with LUTS associated with BPH, especially with concomitant erectile dysfunction.

    Full Text Available Cases of benign infantile convulsions with mild gastroenteritis (BICE treated in our hospital from 2008 to 2012 were analyzed retrospectively. Among the 65 cases of convulsions with acute diarrhea, there were 18 cases of BICE, 15 cases of febrile seizures, 13 cases of epilepsy, 6 cases of viral encephalitis, 6 cases of hyponatremia encephalopathy, 3 cases of hypernatremia encephalopathy, 2 cases of toxic encephalopathy, and 2 cases of hypocalcemia convulsion. The convulsion occurred mostly during the first 2 d of the illness and was in a generalized tonic or tonic-clonic form. Positive rotavirus antigens in the BICE patients were detected in 83.33% (15/18. Phenobarbital was administered after the first convulsion (5-10 mg/kg, and diazepam was given intravenously in case of recurrence (0.10-0.30 mg/kg. BICE occurs frequently in infantile and controlling relapse is the main purpose. The prognosis is good. doi: 10.3969/j.issn.1672-6731.2014.03.019

    The overall program objective is to develop and evaluate environmentally benign agents or products that are effective in the prevention, inhibition, and mitigation of microbially influenced corrosion (MIC) in the internal surfaces of metallic natural gas pipelines. The goal is to develop one or more environmentally benign (a.k.a. ''green'') products that can be applied to maintain the structure and dependability of the natural gas infrastructure. The technical approach for this quarter includes the application of the method of fractionation of the extracts by high performance liquid chromatography (HPLC); determination of antimicrobial activities of the new extracts and fractions using a growth inhibition assay, and evaluation of the extracts' ability to inhibit biofilm formation. We initiated the delivery system for these new biocides in the test cell and in mixtures of foam components and biocides/anti-biofilms. A total of 51 fractions collected by HPLC from crude extracts that were obtained from three varieties of Capsicum sp. (Serrano, Habanero, Chile de Arbol) were subjected to growth inhibition tests against two SRB strains, D. vulgaris and D. desulfuricans. Five fractions showed growth inhibition against both strains while seven inhibited D. desulfuricans only. The crude extracts did not show growth inhibition on both strains but were proven to be potent in preventing the formation of biofilm. Growth inhibition tests of the same set of crude extracts against Comamonas denitrificans did not show positive results. The fractions will be subjected to biofilm inhibition and dissociation assay as well. The delivery system to be evaluated first was foam. The ''foam pig'' components of surfactants and water were tested with the biocide addition. The first chemical and physical parameters to be tested were pH and surfactants. Tests using the fractionated pepper extracts are progressing rapidly. Gas chromatographic analysis

    A 14-year-old boy was referred to the Dermatology Clinic of the Medical University of Mashhad, Iran, with numerous cutaneous telangiectasias on the face, ears, lips, and back of the hands, with lesions in the temporal region being the first to appear (Figs 1-3). His mother stated that the lesions had been present for 10 years with an increase in the past 6 months. He had no history of bleeding from the nose, mouth, gastrointestinal tract, and other mucosal surfaces, and there was no sign of organ involvement. On inspection, no lesions were detected on the nasal mucosa, external ear, over the tympanic membrane, or mouth. The patient is one member of a family of six. His mother is healthy, but similar lesions were seen in his father, sister and one of his brothers with similar distributions. Lesions were also seen in his aunt and paternal grandmother, showing disease distribution in six members of this family from three generations. The oldest brother is 20 years of age and mentioned the onset of disease from the age of 10 years. The sister is 18 years of age and lesions started to appear 7 years ago; she claims that the lesions regress during her menstrual period. The youngest brother is 4 years of age and shows no sign of cutaneous lesions as yet. The parents are not consanguineous. Generalized telangiectasia with a predominant distribution on light-exposed skin, an autosomal dominant inheritance, and no sign of systemic or mucosal involvement and bleeding disorders indicates a diagnosis of hereditary benign telangiectasia. Our patient did not consent to biopsy. PMID:16863520

    We report on the new method of interstitial laser coagulation for the treatment of benign prostatic hyperplasia (BPH). The procedure is based on the interstitial application of Nd:YAG laser irradiation, delivered through a new light guide system. Such light applicators coagulate constant tissue volumes in a homogeneous manner, as proven by in vitro studies in different tissues, including surgically removed prostate adenoma. The extent of the coagulation is determined by laser power and irradiation time. At 5 W, for example, and during a 10-min period, this zone reached a diameter of up to 20 mm. Temperatures generated in the process were over 100 degrees C, as measured by time/space resolution. These results were confirmed by in vivo studies in canine prostates. In the course of 7 weeks, the coagulated areas formed scars with degeneration and fibrosis, accompanied by marked shrinking. Neighbouring organs were not affected. The method was successfully transferred to clinical practice. The application of the light guides to the lateral lobes was performed percutaneously from the perineum under transrectal ultrasound guidance. The median lobe was punctured transurethrally under direct vision. Twenty-seven patients with an average age of 67.7 years were treated between July 1991 and March 1992. At the time of evaluation 15 patients had a follow-up of more than 2 months. They experienced a mean increase of peak flow rate from 6.6 to 15.2 ml/s and a mean decrease of residual volume from 206 to 38 ml. This was accompanied by a marked lessening of symptoms. The average prostate weight decreased from 63 to 44 g. Sexually active patients did not experience retrograde ejaculation.(ABSTRACT TRUNCATED AT 250 WORDS) PMID:7690498

  17. Benign Ancient Schwannoma of the abdominal wall: An unwanted birthday present

    2010-01-01

    Full Text Available Abstract Background There has been a recent growth in the use of whole body Computerised Tomography (CT scans in the private sector as a screening test for asymptomatic disease. This is despite scant evidence to show any positive effect on morbidity or mortality. There has been concern raised over the possible harms of the test in terms of radiation exposure as well as the risk and anxiety of further investigation and treatment for the large numbers of benign lesions identified. Case Presentation A healthy 64 year old lady received a privately funded whole body CT scan for her birthday which revealed an incidental mass in the right iliac fossa. This was investigated with further imaging and colonoscopy and as confident diagnosis could not be made, eventually excised. Histology demonstrated this to be a benign ancient schwannoma and we believe this to be the first reported case of an abdominal wall schwannoma in the English literature Conclusions Ancient schwannomas are rare tumours of the peripheral nerve sheaths more usually found in the head, neck and flexor surfaces of extremities. They are a subtype of classical schwannomas with a predominance of degenerative changes. Our case highlights the pitfalls of such screening tests in demonstrating benign disease and subjecting patients to what turns out to be unnecessary invasive investigation and treatment. It provides evidence as to the consequences of the large number of false positive results that are created by blind CT scanning of asymptomatic patients i.e. its tendency to detect pseudodiesease rather than affect survival rates. Should the number of scans increase there may be an unnecessary burden on NHS resources due to the large numbers of benign lesions picked up, that are then referred for further investigation.

  18. differentiation of benign from malignant lesions of heart and pericardium: the feasibility of Fluorine-18 fluorodeoxyglucose positron emission tomography CT

    International Nuclear Information System (INIS)

    Objective: To assess the feasibility of integrated 18F-FDG PET-CT for the differentiation of malignancy from benign lesions of heart and pericardium. Methods: A total of 23 cases (malignancy: benign = 13:10) with cardiac and pericardial lesions confirmed by pathology or clinic were analyzed in the present study. All lesions were evaluated semi-quantitatively using maximum standard uptake values (SUVmax) and SUVmax lesion/blood, and the density of the heart and pericardium lesions and the relationship with surrounding tissues were evaluated. The differences of SUVmax and SUVmax lesion/blood between benign and malignant lesions were analyzed using Man-Whitney test. Subsequently, the diagnostic sensitivity, specificity, accuracy, positive predictive value (PPV) and negative predictive value (NPV) were calculated for CT and PET-CT respectively. Results: The maximum SUV showed significant difference between malignancy (6.5) and benign (1.5) (Z=-3.601, P18F-FDG PET-CT can correctly differentiate benignity and malignancy of cardiac and pericardial lesions.

    Full Text Available The Distinction between malignant and benign pheochromocytoma has always been a diagnostic challenge over the last decades. To date, the only reliable criterion is metastasis. The aim of the present study was to investigate the possible expression of pituitary-tumor transforming gene (PTTG1 and retinoblastoma (Rb in benign and malignant pheochromocytoma. Paraffin blocks of 44 and 11 patients diagnosed with benign and malignant pheochromocytoma were collected. Parameters such as sex, age, tumor size, necrosis, and histological features were compared between the benign and malignant groups as well as immunohistochemical labeling using specific antibodies. PTTG1 showed negative expression in all (44 benign and 9 out of 11 (81.8% malignant tumors with only 2 out of 11 (18.2% malignant tumors showed positive reactivity for PTTG1 (P: 0.037 with spindle cell histological pattern in both of them (P: 0.013. Although Rb expression in malignant tumors (81.8% was slightly more than the benign ones (52.3%, no statistically significant correlation was observed (P: 0.087. These results suggest that PTTG1 immunostaining may play a key role in distinguishing between benign and malignant phaeochromocytoma. However, larger studies are necessary to confirm the outcomes of the present study.

    Full Text Available : Benign laryngeal lesions are commonly encountered causes of dysphonia and are often surgically correctable. A prospective study on 62 cases selected for videolaryngoscopic surgery was undertaken in a single unit in the department of ENT, Medical College Hospital, Thiruvananthapuram. The male: female ratio was 1.8:1 and the most common affected age group was 35-45 yrs. The most common benign lesion was vocal polyp. Preoperative voice assessment and 70 degree endoscopy was done. Follow up visits were done at 1 week, 3 weeks and 6 weeks and voice assessment and laryngoscopic appearances were noted. 98% reported excellent improvement of voice. The varieties of benign lesions which cause hoarseness are sources of concern and worry as it can affect the self esteem of a person. Thus videolaryngoscopic surgery (VLS coupled with voice therapy offers cost effective and safe management in benign laryngeal lesions

    Robotic technology for use in surgery has advanced considerably in the past 10 years. This has become particularly apparent in urology where robotic-assisted radical prostatectomy using the da VinciTM surgical system (Intuitive Surgical, CA) has become very popular. The use of robotic assistance for benign urological procedures is less well documented. This article considers the current robotic technology and reviews the situation with regard to robotic surgery for benign urological conditions.

  20. Diagnostic value of chemical shift artifact in distinguishing benign lymphadenopathy

    International Nuclear Information System (INIS)

    Purpose: Today, distinguishing metastatic lymph nodes from secondary benign inflammatory ones via using non-invasive methods is increasingly favorable. In this study, the diagnostic value of chemical shift artifact (CSA) in magnetic resonance imaging (MRI) was evaluated to distinguish benign lymphadenopathy. Subjects and methods: A prospective intraindividual internal review board-approved study was carried out on 15 men and 15 women having lymphadenopathic lesions in different locations of the body who underwent contrast-enhanced dynamic MR imaging at 1.5 T. Then, the imaging findings were compared with pathology reports, using the statistics analyses. Results: Due to the findings of the CSA existence in MRI, a total of 56.7% of the studied lesions (17 of 30) were identified as benign lesions and the rest were malignant, whereas the pathology reports distinguished twelve malignant and eighteen benign cases. Furthermore, the CSA findings comparing the pathology reports indicated that CSA, with confidence of 79.5%, has a significant diagnostic value to differentiate benign lesions from malignant ones. Conclusion: Our study demonstrated that CSA in MR imaging has a suitable diagnostic potential nearing readiness for clinical trials. Furthermore, CSA seems to be a feasible tool to differentiate benign lymph nodes from malignant ones; however, further studies including larger numbers of patients are required to confirm our results.

  1. Benign skin disease with pustules in the newborn*

    The neonatal period comprises the first four weeks of life. It is a period of adaptation where the skin often presents several changes: transient lesions, resulting from a physiological response, others as a consequence of transient diseases and some as markers of severe disorders. The presence of pustules in the skin of the newborn is always a reason for the family and for the assisting doctor to be worried, since the newborn is especially vulnerable to bacterial, viral or fungal infection. However, the majority of neonatal skin pustules is not infectious, comprising the benign neonatal pustulosis. Benign neonatal pustuloses are a group of clinical disease characterized by pustular eruptions in which a contagious agent is not responsible for its etiology. The most common ones are erythema toxicum neonatorum, the transient neonatal pustular melanosis and the benign cephalic pustulosis. These dermatoses are usually benign, asymptomatic and self-limited. It is important that the dermatologist and the neonatologist can identify benign and transient lesions, those caused by genodermatoses, and especially differentiate between neonates with systemic involvement from those with benign skin lesions, avoiding unnecessary diagnostic tests and worries.

    A variety of malignant neoplasms have been shown to induce capillary neovascularization, and in some cases the degree of vascularization appears to correlate with aggressive behavior and risk of metastasis. We hypothesized that carcinoma of the prostate also induces the formation of new capillaries, and we developed a method to quantify the relative density of microscopic vessels in carcinoma of the prostate compared with benign prostatic glandular tissue. The number of microvessel profiles in tissue sections was quantified by marking the vascular endothelial cells with antibodies to factor VIII-related antigen using standard immunohistochemistry techniques and comparing fields of adenocarcinoma with benign glandular tissue in 15 radical prostatectomy specimens. The analysis was facilitated by using the Optimas computerized image analysis system (Bioscan, Seattle, WA) with software written for this investigation. Fourteen of the 15 cases demonstrated significantly higher vascular density in the areas of carcinoma than in the benign tissues. Overall, the ratio of vessels per unit area in sections of carcinoma versus benign tissue was approximately double (ratio = 2.02; P < .001). In benign tissues the capillaries are restricted for the most part to the periglandular stroma immediately adjacent to the epithelium, whereas the distribution in carcinoma appears to be more random. The data demonstrate the increased density of capillaries in prostatic carcinoma when compared with benign prostate tissue. PMID:8432518

  4. Sinking fluxes of minor and trace elements in the North Pacific Ocean measured during the VERTIGO program

    2008-07-01

    As part of the Vertical Transport in the Global Ocean (VERTIGO) program, we collected and analyzed sinking particles using sediment traps at three depths in the oceanic mesopelagic zone and at two biogeochemically contrasting sites (N. Central Pacific at ALOHA; N. Pacific Western Subarctic Gyre at K2). In this paper, we present the results of minor and trace element determinations made on these samples. Minor and trace elements in the sinking material showed 2 trends in flux with depth: increasing and constant. The sinking particulate phase of some elements (Al, Fe, Mn) was dominated by material of lithogenic origin and exhibited flux that was constant with depth and consistent with eolian dust inputs (ALOHA), or increasing in flux with depth as a result of lateral inputs from a shelf (K2). This shelf-derived material also appears to have been confined to very small particles, whose inherent sinking rates are slow, and residence time within the mesopelagic "twilight zone" would be consequently long. Furthermore, the flux of this material did not change with substantial changes in the rain of biogenic material from the surface (K2), suggesting mechanistic decoupling from the flux of organic carbon and macronutrients. Micronutrient (Fe, Co, Zn and Cu) fluxes examined in a 1-D mass balance suggest widely differing sources and sinks in the water column as well as impacts from biological uptake and regeneration. For example, total Fe fluxes into and out of the euphotic zone appeared to be dominated by lithogenic material and far exceed biological requirements. The export flux of Fe, however, appeared to be balanced by the eolian input of soluble Fe. For Zn and Cu, the situation is reversed, with atmospheric inputs insufficient to support fluxes, and the cycling therefore dominated by the draw down of an internal pool. For Co, the situation lies in between, with important, but ultimately insufficient atmospheric inputs.

    p53 alterations have been identified in approximately 23% of breast carcinomas, particularly in hormone receptor-negative high-grade carcinomas. It is considered to be an early event in breast carcinogenesis. Nevertheless, the putative precursor lesion of high-grade breast carcinoma remains elusive. Breast excision specimens from 93 triple-negative high-grade invasive ductal carcinomas, 48 estrogen receptor (ER)-positive/progesterone receptor-positive/Her2-negative non-high-grade invasive ductal carcinomas, and 50 mammoplasty breasts were selected. At least 2 tissue blocks with tumor and adjacent benign tissue were sectioned and subjected to immunohistochemistry staining for p53. TP53 gene sequencing was performed on select tumors. Further immunohistochemistry staining for ER and Ki-67 was performed on consecutive sections of tissue with p53-positive normal/benign cells. Of the 93 high-grade carcinomas, 51 (55%) were positive for p53 alteration, whereas only 3 (6.25%) of the 48 non-high-grade carcinomas were p53 altered. Focal p53 positivity in adjacent normal/benign breast tissue was identified in 19 cases, and 18 of them also had p53 alteration in their carcinomas. Only 1 case had focal p53 staining in normal/benign tissue, but the tumor was negative for p53 alteration. No p53 staining positivity was identified in the mammoplasty specimens. The p53-stained normal/benign cells were ER negative and did not show an increase in the Ki-67 labeling index. These findings indicate that the p53 staining positivity in normal/benign breast tissue is not a random event. It could be considered as the "p53 signature" in breast and serve as an indicator for future potential risk of p53-positive high-grade breast carcinoma. PMID:27246177

    We describe Gastrocopta sandbergeri sp. nov. from the Miocene brown coal deposits of the open-cast mine Belchatow (central Poland) and identify it as conspecific with Pupa (Vertigo) suevica Sandberger, 1875 (nomen nudum) from the Miocene of Steinheim. The new species is most similar to Gastrocopta nouletiana (Dupuy, 1850) but differs in having smaller and always slender shell, less convex whorls, much weaker crest on the body whorl (or even absent) and generally rather weakly developed teeth (6-7) in the aperture.

  8. Temporary Placement of Stent Grafts in Postsurgical Benign Biliary Strictures: a Single Center Experience

    International Nuclear Information System (INIS)

    To evaluate the effect of temporary stent graft placement in the treatment of benign anastomotic biliary strictures. Nine patients, five women and four men, 22-64 years old (mean, 47.5 years), with chronic benign biliary anastomotic strictures, refractory to repeated balloon dilations, were treated by prolonged, temporary placement of stent-grafts. Four patients had strictures following a liver transplantation; three of them in bilio-enteric anastomoses and one in a choledocho-choledochostomy. Four of the other five patients had strictures at bilio-enteric anastomoses, which developed after complications following laparoscopic cholecystectomies and in one after a Whipple procedure for duodenal carcinoma. In eight patients, balloon-expandable stent-grafts were placed and one patient was treated by insertion of a self-expanding stent-graft. In the transplant group, treatment of patients with bilio-enteric anastomoses was unsuccessful (mean stent duration, 30 days). The patient treated for stenosis in the choledocho-choledochostomy responded well to consecutive self-expanding stent-graft placement (total placement duration, 112 days). All patients with bilio-enteric anastomoses in the non-transplant group were treated successfully with stent-grafts (mean placement duration, 37 days). Treatment of benign biliary strictures with temporary placement of stent-grafts has a positive effect, but is less successful in patients with strictures developed following a liver transplant.

  9. Malignant and benign diseases of the breast in 41 male patients: mammography, sonography and pathological correlations

    International Nuclear Information System (INIS)

    Aim: The goal of our study was to evaluate findings in mammography and sonography in male patients with pathohistologically proven diseases of the breast. Material and Methods: Mammographies and sonographies, which were obtained in 41 male patients in a 6-year period, were retrospectively evaluated in accordance with the BI-RADS trademark classification. Results: Histologically 13 carcinomas, 21 gynecomastias, 3 pseudogynecomastias, 2 epithelial inclusion cysts and 2 other benign lesions were diagnosed. The sensitivity, specificity, positive predictive value, negative predictive value and accuracy of mammography in differentiation of benign versus malignant disease were 92%, 89%, 80%, 96% and 90%, respectively. Additional sonography did not change these results. However, sonography increased diagnostic confidence in 18.2% (2/11) of suspicious lesions. Conclusion: In our study the invasive ductal carcinoma of male patients was a predominantly lobulated, ill-defined lesion in mammography and sonography. The differentiation of carcinoma to pseudogynecomastia and diffuse or dendritic gynecomastia was securely feasible. However, we could not reliably distinguish between carcinoma and some benign mass lesions. In cases of mammographically diagnosed masses or unclear mammography, additional sonography should be performed to increase the diagnostic confidence. (orig.)

  11. Orthopedic surgery-related benign uptake on FDG-PET. Case examples and pitfalls

    International Nuclear Information System (INIS)

    Orthopedic surgical procedures often create some special postoperative complications, which may demonstrate abnormally increased or focal uptake for an extended period of time on fluorodeoxyglucose (FDG) positron emission tomography (PET)-CT images. The distinction of normal from pathologic, benign from malignant uptake is very important to minimize the number of false positive results. To date, very little data have been published regarding surgical-related benign musculoskeletal uptake on PET-CT imaging. In this paper, we present to the readers some case examples of FDG PET-CT imaging for postoperative fracture, infection or osteomyelitis, metallic implants, aggressive bone edge, heterotopic ossification, granuloma and neuroma. We also discuss potential pitfalls to recognize these orthopedic surgery-related complications and identify benign nature of increased FDG uptake. In all cases, the patient's medical and surgical history would be of paramount importance to the radiologists/nuclear medicine physicians who interprets the scan. It is also crucial to carefully correlate FDG uptake with the anatomy on the co-registered CT images in all transaxial, coronal and sagittal views in order to identify the location and pattern of uptake.

    AIM: To identify the criteria for the differentiation of hilar cholangiocarcinoma (HCCA) from benign strictures.METHODS: A total of 68 patients underwent resection of lesions suspicious for HCCA between 1998 and 2006. The results of laboratory investigations, imaging studies and brush cytology were collected. These findings were analyzed to obtain the final diagnosis. RESULTS: Histological examination of the resected specimens confirmed HCCA in 58 patients (85%, group Ⅰ) whereas 10 patients (15%, group Ⅱ)were diagnosed to have benign strictures. The most common presenting symptom was obstructive jaundice in 77% patients (79% group Ⅰ vs 60% group Ⅱ, P =0.23). Laboratory findings showed greater elevation of transaminase levels in group I compared to group Ⅱ. The various imaging modalities showed vascular involvement exdusively in the malignant group (36%,P < 0.05). Brush cytology was positive for malignant cells in only 50% patients in group Ⅰ whereas none in group Ⅱ showed malignant cells.CONCLUSION: Despite improvements in imaging techniques, 10 patients (15%) with a presumptive diagnosis of HCCA were ultimately found to have benign strictures. Except for vascular involvement which was associated significantly with malignancy,there were no conclusive features of malignancy on regular imaging modalities. This uncertainty should be taken into account when patients with a suspicious lesion at the liver hilum are considered for resection.

    2005-05-01

    Full Text Available HBME-l is an antimesothelial monoclonal antibody that recognizes an unknown antigen on microvilli of mesothelial cells. The antibody is only relatively specific for mesothelium and is used in the differential diagnosis of mesothelioma and adenocarcinoma within the context of an appropriate immuno-histochemical panel. HBME-l has also been reported to strongly and uniformly stain papillary and follicular carcinoma of the thyroid while benign disorders have been usually negative. We studied the immunoreactivity of HBME-l in 90 cases of benign and malignant thyroid lesions. We found strong positive staining in the majority of papillary carcinomas (28/31, in some of follicular carcinomas (4/6,and in a few follicular adenomas (2/17. Negative staining was found in oxyphilic cell adenoma (0/4, nodular goiter (0/13 and undifferentiated carcinoma. The results suggest that monoclonal antibody HBME-l is useful in differentiating papillary and follicular carcinoma of the thyroid from benign lesions, especially in more differentiated lesions. Strong and generalized immunoreactivity for HBME-l in a follicular lesion should raise the suspicion of malignancy, but negative staining specially in poorly differentiated lesion does not rule out malignancy.

    AIM To evaluate the effects of expandable metallic stent biliary endoprostheses (EMSBE) viaultrasonographic guided percutaneous transhepatic approach on the treatment of benign and malignantobstructive jaundice.METHODS Thirty-eight patients with obstructive jaundice (29 males and 9 females) aged 27 to 69 years(mean 54.7 years) were studied. Of them, 4 were benign and 34 malignant obstructions. Percutaneoustranshepatic cholangiography (PTC) was performed under ultrasonic guidance. A catheter was introducedinto the dilated bile duct via the introducer. A guide wire was inserted through the occlusive part of biliary duct after dilating with a double-lumen balloon catheter. A self-expandable metallic stent was inserted intcthe occlusive bile duct under fluoroscopic control.RESULTS The success rate of sonographic guided PTC was 100% (38/38) and the success rate of stentimplantation was 86.8% (33/ 38). Biliary obstruction was eliminated immediately, jaundice subsidedgradually and symptoms relieved after the procedure. During the 3 to 28 months fellow-up, re-occlusionoccurred in 4 malignant cases which were corrected by balloon catheter dilation and/or by stent, one patienthad secondary cholangitis and fifteen died without jaundice 6 - 28 months after the procedure. The otherswere alive with no jaundice. No severe complications or side effects were observed.CONCLUSION EMSBE via sonographic guided percutaneous transhepatic approach is a reliable and safepalliative therapy for malignant jaundice and an ideal nonoperative method for benign biliary obstruction. Ithas a definite positive impact on the quality of patient life.

    Objective.To determine the apoptotic and proliferative activities in various ovarian epithelial tumors.Methods.Formalin fixed,paraffin embedded tissues of 86 ovarian epithelial tumors,including 52 adenocarcinomas,23 borderline tumors and 11 cystadenomas,were retrieved.Apoptotic (AI) and proliferative (PI) index were estimated using the monoclonal antibodies: M30,Ki 67 and Ki S1 in these tumors.Quantitative assessment of AI and PI was estimated by calculating the percentage of positive cells among no less than 1000 tumor cells.Results.Statistically significant difference in AI was found between benign and borderline tumors or carcinomas (P=0.028,0.001,respectively).Significant differences in PI,as assessed by both Ki 67 and topo IIα,were demonstrated between carcinomas and benign or borderline tumors (both P< 0.001).Benign tumors had both low PI and AI; borderline tumors had lower PI but higher AI,while adenocarcinomas had both high proliferative and high apoptotic rates.Among borderline tumors,serous tumors had significantly lower AI and higher PI than mucinous ones.Conclusions.The results suggest that apoptotic and proliferative activities play important roles in the pathogenesis and development of ovarian borderline and malignant tumors.The high apoptotic rate in borderline tumor may explain its relatively indolent behavior while the high proliferative rate in carcinomas tends to explain its aggressive behavior.

  17. Differentiation of benign and malignant lymph nodes with ADC value on diffusion MR: a Meta-analysis

    International Nuclear Information System (INIS)

    Objective: To summarize the diagnostic efficacy of ADC value for differentiation of benign and malignant lymph nodes on diffusion MRI with Meta-analysis. Methods: Published papers on differentiation of benign and malignant lymph nodes with ADC value were searched and reviewed. Quality evaluation was performed for the eligible papers before data extraction.Test for heterogeneity was performed first, then appropriate model was selected to calculate the weighted mean difference, sensitivity, specificity, positive likelihood ratio, negative likelihood ratio, diagnostic odds ratio,pretest and posttest probability. The potential of ADC value for differentiation of benign and malignant lymph nodes was assessed qualitatively and quantitatively. Results: Fifteen papers including 735 cases and 1963 lymph nodes were selected. According to Meta-regression analysis, subgroup analysis and robust analysis, two studies with benign lymph nodes in patients with benign lesion and one study using chemical shift saturation technique were excluded because of their impact on the robustness of the pooled results. The weighted mean difference (WMD) between malignant and benign lymph nodes was -0.355 × 10-3 mm2/s [95% confidence interval (CI):-0.423 ×10-3- -0.288 × 10-3 mm2/s]. Although the cutoff of ADC value for differentiation in each study was different, the diagnostic efficacy was stable, the pooled sensitivity,specificity, positive likelihood ratio, negative likelihood ratio, diagnostic odds ratio and area under summarized receiver operator's curve were 0.87 (95% CI: 0.79-0.92), 0.87 (95% CI: 0.82-0.90), 6.5 (95% CI: 4.7-9.2), 0.15 (95% CI: 0.09-0.25), 43 (95% CI: 21-87), 0.93 (95% CI: 0.90-0.95). The posttest malignancy probability of benign lymph node indicated by ADC was 6%, while that of malignant lymph node was 72%. Conclusion: The ADC value can be used to differentiate benign and malignant lymph nodes with good sensitivity and specificity noninvasively. (authors)

  18. Role of diffusion MRI in characterizing benign and malignant breast lesions

    International Nuclear Information System (INIS)

    The aim of this study was to evaluate the role of MRI based diffusion-weighted imaging (DWI) and the apparent diffusion coefficient (ADC) for characterizing breast lesions in Indian patients. This prospective analysis was performed between October 2006 and June 2008. It includes 200 patients between the ages of 16 and 80 years with solid breast lesions greater than 1 cm in diameter. Of these 200 patients, 80 underwent breast MRI with contrast and DWI. One hundred and twenty patients had only DWI as they had come only for sonomammography. A total of 280 lesions were detected. ADC values were calculated for all the lesions and the highest and lowest values of ADC for benign and malignant lesions were identified. Finally, we compared our findings with those of previous studies. Two hundred and eight lesions were categorized as benign and 72 lesions were categorized as malignant based on the ADC values. Based on previous data, lesions with ADC values from 1.3 to 1.5 mm2/s were considered benign where as lesions with ADC values ranging between 0.85 and 1.1 mm2/s were considered malignant. Two lesions whose ADC values were in the benign range were proven to be malignant tumors after surgery. This method of using ADC values for the detection of malignant lesions showed a sensitivity of 97.22% and a specificity of 100%. The positive predictive value was 100%. DWI is a useful technique for characterizing breast tumors, especially for lesions that cannot be adequately characterized by ultrasonography and routine magnetic resonance imaging

  19. Incidental benign parotid lesions on FDG-PET: prevalence and clinico-pathologic findings

    International Nuclear Information System (INIS)

    Incidental parotid lesions on F-18 FDG-PET can mimic distant metastasis of underlying malignancy. The prevalence and the clinico-pathologic findings of PET positive parotid lesions have not been known. We investigated how often incidental parotid lesions are found on clinical FDG-PET studies and what the clinico-pathologic characteristics of those parotid lesions are in the present study. We retrospectively reviewed 3,344 cases of FDG-PET which had been obtained in our hospital from May 2003 to Dec 2006. The indications of FDG-PET were: evaluation of known/suspected cancer (n = 3,212) or screening of cancer in healthy subjects (n = 132). Incidental parotid lesion on FDG-PET was defined as an un-expected FDG uptake in one of parotid glands which was not primary target lesion of current FDG/PET. FDG uptake was represented by maximum standardized uptake value (maxSUV). Final diagnosis was made by pathologic analysis or clinical follow-up assessment. Fifteen (0.45% = 15/3,344) incidental parotid lesions were found and they were all benign lesions. The maxSUV ranged from 1.7 to 8.6 (mean ± s.d. = 3.7 ± 1.9). Final diagnoses of the incidental parotid lesions were; Warthin's tumor (n = 2), pleomorphic adenoma (n = 1), other un-specified benign lesion (n 1), and benign lesions under bases of imaging studies (n = 3) and of clinical follow-up (n = 8). All of incidentally found parotid lesions in clinical FDG-PET studies were confirmed as benign lesions with prevalence of 0.45%. Close follow up using PET or CT might be a reasonable approach for determining the nature of incidentally found parotid lesions

  20. Diffusion-weighted MRI for differentiation of benign from malignant lesions in the gallbladder

    International Nuclear Information System (INIS)

    Aim: To investigate the value of diffusion-weighted imaging (DWI) for differentiating benign from malignant gallbladder lesions. Materials and methods: One hundred and twenty-six patients who had undergone magnetic resonance imaging (MRI) with DWI, in whom the histopathological diagnosis of their gallbladder lesions was confirmed by biopsy or surgery were retrospectively analysed. Thirty-six malignant and 90 benign lesions were included. Two radiologists categorized gallbladder lesions into seven types on two imaging sets [T2-weighted imaging (WI) alone and combined T2WI and DWI (b = 800 s/mm2)] according to the presence of wall thickening, layered patterns, morphology of the mass, and diffusion restriction. Disagreements were resolved in consensus. The sensitivity, specificity, positive predictive value (PPV), and negative predictive value (NPV) of each imaging set for diagnosing gallbladder carcinoma were calculated. The diagnostic performance of each imaging set was calculated using receiver operating characteristic (ROC) curve analysis. Additionally, ADC values of malignant and benign gallbladder lesions were compared separately for 1.5 and 3 T MRI. Results: The sensitivity, specificity, PPV, and NPV of diagnosis at T2WI were 97.2%, 86.7%, 74.5%, and 98.7%, respectively. The sensitivity, specificity, PPV, and NPV using combined T2WI and DWI were 97.2%, 92.2%, 83.3%, and 98.8%, respectively. Diagnostic accuracy for gallbladder carcinoma slightly improved after adding DWI, from 0.92 to 0.95 (p −3 and 1.72 ± 0.56 × 10−3 mm2/s, respectively, at 1.5 T (p −3 and 2.2 ± 0.72 × 10−3 mm2/s, respectively, at 3 T (p < 0.001). Conclusion: DWI can improve diagnostic accuracy for differentiating benign from malignant gallbladder lesions

    Radiological and pathological correlation of the full range of benign breast lesions, with emphasis on screen-detected lesions. Detailed discussion of risk assessment. Revised and updated edition, with a new chapter on gynaecomastia. Ideal aid to the management of patients with benign or indeterminate breast lesions in a multidisciplinary setting. The second edition of this book has been extensively revised and updated. There have been numerous scientific advances in the radiology, pathology and risk assessment of benign breast lesions since the publication of the first edition. The first edition concentrated on screen-detected lesions, which has since been rectified; new symptomatic and screen-detected lesions are discussed in the second edition and include: mastitis and breast abscesses, idiopathic granulomatous mastitis, diabetic mastopathy, phyllodes tumours, gynaecomastia and pseudoangiomatous stromal hyperplasia. The chapters on columnar cell lesions and mucocele-like lesions have been extensively updated. Where applicable, genetic analysis of the benign lesions, which is becoming part of personalised medicine in the field of breast cancer, has been included. The book also presents detailed analyses of the main models, such as the Gail Model, used to assess the subsequent risk of breast cancer in individuals. The current trend in the management of all cancers is preventative. Screening mammography detects early curable cancers as well as indeterminate lesions, the latter of which are invariably pathologically benign. The author has collated important benign lesions and, based on peer-reviewed publications, has documented the relative risk of subsequent cancer to allow the patient and the clinician to implement preventative measures where possible. This book will therefore serve as an essential component of multidisciplinary management of patients with symptomatic and screen-detected benign breast lesions.

    The author reviewed clinical aspects of vestibular evoked myogenic potentials (VEMPs). Now two types of VEMPs are available. The first one is cervical VEMP, which is recorded in the sternocleidomastoid muscle and predominantly reflects sacculo-collic reflex. The other is ocular VEMP, which is usually recorded below the lower eye lid and predominantly reflects utriculo-ocular reflex. VEMPs play important roles not only for assessment of common vestibular diseases but also for establishment of new clinical entities. Clinical application in Meniere's disease, vestibular neuritis, benign paroxysmal positional vertigo, vestibular migraine, idiopathic otolithic vertigo, and central vertigo/dizziness was reviewed.

    Objective:This sudy was designed to observe somatostatin receptor subtype 2 (SSTR2) Mrna expression, and investigate the correlations between SSTR2 Mrna expression and steroid receptors in benign and malignant lesions of the breast. Methods: A total of 23 breast carcinomas,16 mammary hyperplasia and 9 mammary adenofibroma samples were analysed. The SSTR2 Mrna expression was examined by in situ hybridization using multiphase oligoprobes.The ER and PR were detected by immunohistochemical staining. A computerized image analysis system was utilized to estimate the relative contents of SSTR2 Mrna. Results: The positive rates of expression (87.0%) and relative contents (0.47) of SSTR2 Mrna in breast cancer were higher than those in benign breast lesions(64%,0.26) respectively( P<0.05). SSTR2 Mrna expression was closely correlated with ER and PR in breast cancer( P<0. 05), A positive correlation between SSTR2 Mrna expression and ER was also found in benign breast lesions. Conclusions: SSTR2 Mrna expressed both in benign and in malignant breast lesions, but higher in malignant than in benign ones. There was a significant positive correlation of SSTR2 Mrna expression with ER or PR. The results suggest that conbined treatment with an antiestrogen and a somatostatin analogue for ER-positive breast cancer is feasible.

    Comparison of magnetic resonance elastography (MRE) and diffusion-weighted imaging (DWI) for differentiating malignant and benign focal liver lesions (FLLs). Seventy-nine subjects with 124 FLLs (44 benign and 80 malignant) underwent both MRE and DWI. MRE was performed with a modified gradient-echo sequence and DWI with a free breathing technique (b = 0.500). Apparent diffusion coefficient (ADC) maps and stiffness maps were generated. FLL mean stiffness and ADC values were obtained by placing regions of interest over the FLLs on stiffness and ADC maps. The accuracy of MRE and DWI for differentiation of benign and malignant FLL was compared using receiver operating curve (ROC) analysis. There was a significant negative correlation between stiffness and ADC (r = -0.54, p < 0.0001) of FLLs. Malignant FLLs had significantly higher mean stiffness (7.9kPa vs. 3.1kPa, p < 0.001) and lower mean ADC (129 vs. 200 x 10{sup -3}mm{sup 2}/s, p < 0.001) than benign FLLs. The sensitivity/specificity/positive predictive value/negative predictive value for differentiating malignant from benign FLLs with MRE (cut-off, >4.54kPa) and DWI (cut-off, <151 x 10{sup -3}mm{sup 2}/s) were 96.3/95.5/97.5/93.3 % (p < 0.001) and 85/81.8/88.3/75 % (p < 0.001), respectively. ROC analysis showed significantly higher accuracy for MRE than DWI (0.986 vs. 0.82, p = 0.0016). MRE is significantly more accurate than DWI for differentiating benign and malignant FLLs. (orig.)

  8. Benign versus malignant lymphadenopathy : the usefulness of color doppler sonography

    International Nuclear Information System (INIS)

    To evaluate the vascular pattern of lymph nodes, and the usefulness of color Doppler sonogaphy in differentiating benign from malignant superficial lymphadenopathy. Twenty-six patients were pathologically and clinically confirmed to be suffering from benign reactive lymphadenitis and tuberculosis (n=16) or lymphoma and malignant lymphadenitis (n=10). Lymph node shape was assessed by the ratio of longitudinal diameter to transverse diameter(L/T), and patients were thus assigned to one of two groups : L/T≥2, or L/T<2. The hilar vascular pattern of lymph node was assessed by color Doppler sonography and classified as central, eccentric, or absent. On the basis of peripheral vascularity, patients were divided into three groups according to circumferental linear vascularity. An absence of peripheral vascularity was classified as grade 0. If less than half the periphery was covered by linear vascularity, a patient was assigned to as grade I, and if more than half was covered by a vessel, the classification was grade II. Statistically significant differences in L/T ratio were noted between malignant and benign node (p<.001). Of the 16 benign reactive nodes, 13 showed L/T≥2, and 3 L/T<2. while in nine of the ten malignant nodes, L/T<2 was noted. Among 16 benign reactive nodes, hilar vascularity was central in 13, eccentric in one, and absent in two. Among the ten malignant nodes, the corresponding totals were nil, four, and Six. The hilar vascular pattern showed statistically significant differentiation between malignant and benign node (p<.05). Among 16 benign reactive nodes, 13 were grade 0, two were grade I, and one was grade II, while among ten malignant nodes, two were grade 0 and eight were grade I. On the basis of vascular pattern, the difference between benign and malignant nodes was statistically significant (p<.05). L/T ratio<2, absent or eccentric hilar vascularity, and the presence of peripheral vascularity are suggestive of malignant lymph node. The shape

  9. Intraosseous Benign Lesions of the Jaws: A Radiographic Study

    International Nuclear Information System (INIS)

    Benign maxillo-mandibular tumors and cysts, which are relatively common findings on radiographs, namely the ubiquitous panoramic view, have to be dealt with by dentists on a daily basis. The aim of this study is to evaluate the panoramic radiographic findings pertaining to benign and tumoral lesions in the maxilla and mandible. Applying a case series method, panoramic images of 61 patients with cysts, benign tumors and tumor-like lesions in the jaws who were referred to Hamedan dental school between 2009 and 2011 were evaluated by two radiologists. They were both blind to histopathological results as well as the objectives of our study. Lesions were assessed based on their location, periphery, internal structure and impaction on the surrounding structures. Then the obtained data were analyzed using descriptive tables. Cysts were mostly more common in men despite the equal propensity of both genders to benign tumors. In contrast, women showed a higher frequency of tumor-like lesions. The most common site of involvement was the posterior mandible, with peri-apical tooth lesions as the most prevalent dental association. Radiographically, what we most encountered was unilocular radiolucency pertaining to cysts and benign tumors; nevertheless, tumor-like lesions tended to present with a well-defined radiopacity. Despite its known shortcomings, like every other diagnostic tool, panoramic radiography can contribute to the early detection of maxillary/mandibular lesions that in turn enable the dentist to devise an appropriate treatment plan

    Full Text Available Abstract Cystic mesotheloma is an uncommon lesion of the peritoneum occurring predominantly in women of reproductive age. The case was a 21 years girl presented with 4 years history of mild abdominal distension and periodic pain. The results of the clinical examinations were normal. Sonography and CT scan confirmed gross ascites. The results of paraclinical tests were normal without any positive findings for etiology of ascites. During laparoscopy multiple transparent cysts were found in pelvic and culdesac. All cysts were removed by laparoscopy. Histology confirmed benign cystic mesotheloma. Reviewing the records revealved that this case is the second case of mesothelial cysts that presented with ascites.

    2015-09-01

    Benign biliary strictures are common and occur either from hepato-biliary surgery or from diseases including chronic pancreatitis and primary sclerosing cholangitis, among others. The treatment of many such strictures is endoscopic with evolving new approaches especially with fully covered metal stents. The only classification system available is for postoperative strictures with the intention to guide surgical correction. There is no useful classification system to guide both assessment and management of benign biliary strictures. This proposed classification is relevant to patient care in assisting diagnosis and endoscopic management. PMID:26147976

    CT or MRI are utilized in the initial evaluation of adrenal incidentalomas; however, overlap exists between benign and malignant lesions on these examinations. The American College of Radiology recommends PET scans to complement CT and MRI for patients with adrenal masses and a moderate-to-high likelihood of neoplastic disease. We present images of a PET-avid adrenal lesion in a patient with pulmonary and pancreatic neoplasms that mimicked metastasis, but was found to be a benign adrenal hemangioma on surgical resection. The use of PET for adrenal tumors, specifically adrenal hemangiomas, will be reviewed. PMID:24089061

    The first case of benign lentigo of the uterine cervix is reported, providing further evidence that the cervix is able to form the entire spectrum of melanocytic lesions known to occur in the skin. Review of the literature reveals 19 cases of primary malignant melanoma of the cervix and 30 cases of blue nevus. The reported case offers support that benign lentigines may play a role as premalignant lesions of malignant melanoma not only in the skin, but aldo in mucous membranes. PMID:7327080

    A case of hereditary benign telangiectasia without family history was reported. A 39-year-old woman presented with small and tiny telangiectases on the face, neck, upper trunk and forearms at birth. The numbers and sizes of the lesions increased gradually and she had no hemorrhagic diathesis and systemic diseases. No similar patients were found in her family. Upon physical examination, telangiectases were found on the face, neck, upper trunk and forearms; and a telangiectatic erythema was found on the right forearm 25 mm ×40 mm in size. Histopathology examination showed a normal epidermis and dilation of the capillaries at upper dermis. Hereditary benign telangiectasia without family history was diagnosed.

  19. Radiation therapy of benign diseases. What's new eight years after?

    International Nuclear Information System (INIS)

    The authors present an update version of the indications for radiotherapy in the management of benign diseases. This is based on available randomized trials and recent international meetings. Validated indications remain the prevention of resected heterotopic bone ossifications, keloids scars and pterygium and also treatment of arteriovenous malformations; the place of radiotherapy for malignant exophthalmia is more and more restricted. Randomized trials have demonstrated the efficacy of endo-brachytherapy in the prevention of restenosis after angioplasty but the use of embedded stent has replaced this indication. Macular degeneration is no more an indication of radiotherapy. Quality requirements for radiotherapy are identical for benign or malignant indications. (author)

  3. The differentiation of benign from malignant soft tissue lesions using FDG-PET: comparison between semi-quantitative indices

    International Nuclear Information System (INIS)

    The purpose of this study is to evaluate the diagnostic accuracy of various quantitative indices for the differentiation of benign from malignant primary soft tissue tumors by FDG-EPT. A series of 32 patients with a variety of histologically or clinically confirmed benign (20) or malignant (12) soft tissue lesions were evaluated with emission whole body (5min/bed position) PET after injection of [18F]FDG. Regional 20min transmission scan for the attenuation correction and calculation of SUV was performed in 16 patients (10 benign, 6 malignnant) followed by dynamic acquisition for 56 min. Postinjection transmission scan for the attenuation correction and calculation of SUV was executed in the other 16 patients (10 benign, 6 malignant ). The following indices were obtained: the peak and average SUV (pSUV, aSUV) of lesions, tumor-to-background ratio acquired at images of 51 min p.i. (TBR51), tumor-to-background ratio of areas under time-activity curves (TBRarea) and the ratio between the activities of tumor ROI at 51 min p.i. and at the time which background ROI reaches maximum activity on the time-activity curves (T51/Tmax). The pSUV, aSUV, TBR51, and TBRarea in malignant lesions were significantly higher than those in benign lesions. We set the cut-off values of pSUV, aSUV, TBR51, TBRarea and T51/max for the differentiation of benign and malignant lesions at 3.5, 2.8, 5.1, 4.3 and 1.55, respectively. The sensitivity, specificity and accuracy were 91.7%, 80.0%, 84.4% by pSUV and aSUV, 83.3%, 85.0%, 84.4% by TBR51, 83.3%, 100%, 93.8% by TBRarea and 66.7%, 70.0%, 68.8% by T51/Tmax. The time-activity curves did not give additional information compared to SUV or TBR. The one false negative was a case with low-grade fibrosarcoma and all four false positives were cases with inflammatory change on histology. The visual analysis of FDG-PET also detected the metastatic lesions in malignant cases with comparable accuracy. In conclusion, all pSUV, aSUV TBR51, and TBRarea are

    To evaluate the accuracy of benign core biopsy of probably benign breast lesions (category 3) 2 cm or larger on the basis of excisional biopsy and long-term follow-up. We retrospectively reviewed 146 category 3 lesions in 146 patients 2 cm or larger which were diagnosed as benign by ultrasound (US)-guided core biopsy. Patients were initially diagnosed as benign at core needle biopsy and then followed up with excisional biopsy (surgical excision, n=91; US-guided vacuum assisted excision, n=35) or breast ultrasonography (n=20). Of the 126 patients who underwent surgical excision or US-guided vacuum-assisted excision, 114 patients were diagnosed with benign lesions, 10 patients with borderline lesions (benign phyllodes tumor), and two patients with malignant phyllodes tumors. The probabilities of lesions being benign, borderline and malignant were 91.8% (134/146), 6.8% (10/146), and 1.4% (2/146), respectively. Of 13 patients who had growing masses on follow-up ultrasonography, three (23.1%) were non-benign (two benign phyllodes tumors and one malignant phyllodes tumor). US-guided core needle biopsy of probably benign breast mass 2 cm or larger was accurate (98.6%) enough to rule out malignancy. But, it was difficult to rule out borderline lesions even when they were diagnosed as benign.

    Caveolin-1, a tyrosine-phosphorylated protein, is supposed to have different regulatory roles as promoter or suppressor in many human cancers. However, no published study concerned its expression in benign and malignant salivary gland tumors. The aim of this study was to evaluate and compare the expression of Cav-1 in the most common benign and malignant salivary gland tumors and evaluate its correlation with proliferation activity. In this cross-sectional retrospective study, immunohistochemical expression of caveolin-1 and Ki67 were evaluated in 49 samples, including 11 normal salivary glands, 15 cases of pleomorphic adenoma (PA), 13 adenoid cystic carcinomas (AdCC), and 10 mucoepidermoid carcinomas (MEC). The expression of Cav-1 was seen in 18 % of normal salivary glands and 85 % of tumors. The immunoreaction in the tumors was significantly higher than normal tissues (P = 0.001), but the difference between benign and malignant tumors was not significant (P = 0.07). Expression of Cav-1 was correlated with Ki67 labeling index in PAs, but not in malignant tumors. Cav-1 expression was not in association with tumor size and stage. Overexpression of Cav-1 was found in salivary gland tumors in comparison with normal tissues, but no significant difference was observed between benign and malignant tumors. Cav-1 was inversely correlated with proliferation in PA. Therefore, this marker may participate in tumorigenesis of salivary gland tumors and may be a potential biomarker for cancer treatments.

    2004-11-01

    Full Text Available Background: Attempts to differentiate benign and malignant vertebral fractures may bedifficult, particularly when there is no obvious evidence of malignancy.Since early diagnosis and appropriate management of malignant vertebralfractures are important, a reliable imaging modality is required.Methods: From January 1996 to December 2002, 48 patients with malignant vertebralfractures and 50 patients with benign processes were studied. All patientsunderwent conventional magnetic resonance imaging (MRI scanning foracute vertebral compression fractures within 2 months of presenting with thecomplaint. Seven MRI characteristics were used as criteria, including signalintensity, gadolinium enhancement, epidural compression, multiple compressionfractures, associated paraspinal soft tissue mass, pedicle involvement,and posterior element involvement. The predictive value of each MRI characteristicfor distinguishing malignant from benign osteoporotic vertebralfractures was tested by statistical analysis.Results: Lesions with negative gadolinium enhancement were favored as benignfractures. A uniform signal change in multiple involved vertebra lesions,round, smooth margins with marked epidural compression, a paraspinal softtissue mass, and pedicle and posterior element involvement were probablemalignant characteristics. Among them an associated paraspinal soft tissuemass was found to be significant in predicting the probability of malignancy.Conclusions: Certain MRI characteristics allow early differentiation of benign and malignantvertebral fractures.

    The relationship between methylxanthine (Mx) consumption and benign breast disease was evaluated in a case-control study of 288 women with histologically confirmed benign breast lumps (203 dysplastic lesions and 85 benign tumors) and 2 groups of control women--285 patients in the hospital for acute conditions apparently unrelated to the consumption of Mx-containing beverages and 291 outpatients. The relative risk estimates of dysplastic breast lesions (fibrocystic disease), with allowance for all identified potential distorting factors, for women who drank 1-2 or 3 or more cups of coffee per day were 4.1 and 6.4, respectively, when the hospital controls were the comparison group and 2.0 and 3.7, respectively, when the outpatient controls were the comparison group. The relationship was even stronger when the total consumption of Mx-containing beverages (coffee plus tea) was considered and increased with increasing duration of use. The association was not explained by any of the major risk factors for fibrocystic breast diseases or by differences in general characteristics or other lifestyle habits between cases and controls. Mx consumption was not related to the risk of benign breast tumors (fibroadenomas). These findings support the hypothesis that Mx consumption is related to the risk of dysplastic lesions of the breast. PMID:3858587

    Fine-needle aspiration cytology is the standard technique to diagnose thyroid pathologies. However, this method results in a high percentage of inconclusive and false negatives. The use of time-resolved fluorescence techniques to detect biochemical composition and tissue structure alterations could help to develop a portable, minimally invasive, and nondestructive method to assist during surgical procedures. This study aimed to use fluorescence lifetimes to differentiate healthy and benign tissues from malignant thyroid tissue. The thyroid tissue was excited at 298-300 nm and the fluorescence decay registered at 340 and 450 nm. We observed fluorescence lifetimes at 340 nm emission of 0.80±0.26 and 3.94±0.47 ns for healthy tissue; 0.90±0.24 and 4.05±0.46 ns for benign lesions; and 1.21±0.14 and 4.63±0.25 ns for malignant lesions. For 450 nm emissions, we obtain lifetimes of 0.25±0.18 and 3.99±0.39 ns for healthy tissue, 0.24±0.17 and 4.20±0.48 ns for benign lesions, 0.33±0.32 and 4.55±0.55 ns for malignant lesions. Employing analysis of variance, we differentiate malignant lesions from benign and healthy tissues. In addition, we use quadratic discriminant analysis to distinguish malignant from benign and healthy tissues with an accuracy of 76.1%, sensitivity of 74.7%, and specificity of 83.3%. These results indicate that time-resolved fluorescence can assist medical evaluation of thyroid pathologies during surgeries.

  1. 18FDG PET scanning of benign and malignant musculoskeletal lesions

    International Nuclear Information System (INIS)

    To describe the technique, applications and advantages of 18FDG PET scanning in detection, analysis and management of musculoskeletal lesions.Design and patients Forty-five patients (19 males,26 females) aged 9 to 81 years had radiographs, routine radionuclide scans, CT and/or MRI of clinically suspected active benign or malignant musculoskeletal lesions. 18FDG scans with a Siemens ECAT EXACT 921 dedicated PET unit (Knoxville, Tenn.) and FWH=6 mm images acquired as a 5-6 bed examination (6 min emission and 4 min transmission) used OSEM iterative reconstruction with segmented transmission attenuation correction and a Gaussian filter (cutoff 6.7 mm). Region of interest (ROI) 3 x 3 pixel image analysis based on transverse whole body images (slice thickness 3.37 mm) generated Maximum Standard Uptake Values (Max SUV) with a cutoff of 2.0 used to distinguish benign and malignant lesions. Thirty-nine studies were available for SUV ROI analysis. Overall sensitivity for differentiating malignant from benign osseous and non-osseous lesions was 91.7% (22/24), overall specificity was 100% (11/11) with an accuracy of 91.7%. All aggressive lesions had a Max SUV >2.0. Data separating benign from malignant lesions and aggressive from benign lesions were statistically significant (P18FDG PET contributes unique information regarding metabolism of musculoskeletal lesions. By supplying a physiologic basis for more informed treatment and management, it influences prognosis and survival. Moreover, since residual, recurrent or metastatic tumors can be simultaneously documented on a single whole body scan, PET may theoretically prove to be cost-effective. (orig.)

    The non-surgical treatment of vestibular disorders must be based on current knowledge of vestibular pathophysiology. It is generally accepted that after vestibular lesions a self-repair mechanism exists that allows a more or less complete recovery. In cases of persisting vestibular complaints the physician's duty consists in stimulation of these pre-existing mechanisms. This can be done by physical exercises, as has been recommended since the work of Cawthorne and Cooksey in 1946. This concept is meanwhile supported by modern neurophysiological research. This article describes a short training program consisting of exercises for fixation during rotations, smooth pursuit, optokinetic nystagmus and motor learning mechanisms. Physical exercises can be reinforced by nootropic drugs. PMID:8335490

    Purpose: : MR-Mammography (MRM) is regarded as the most sensitive method for detection of breast cancer without a broad consensus on specificity. There is room for improvement of the existing ACR BIRADS lexicon by adding new and specific descriptors. Dilated ducts have been described in association with papillomas. However, the differential diagnostic value of this finding has not been investigated yet. Materials and methods: : 316 consecutive patients, undergoing histopathologic workup after MR-Mammography were included in this prospective, ethical review board approved study. Two blinded radiologists rated the images in consensus. Ductal obstruction was defined as dilated liquid filled ducts proximal an enhancing lesion. Sensitivity, specificity as well as positive and negative likelihood ratio (LR+, LR-) were calculated. Results: Dilated ducts were found in 60 cases (19%), 20 of these showed an association with enhancing lesions and were categorized as ductal obstruction (6.3%). Malignancy was found in two cases (one invasive ductal carcinoma and one DCIS) and benign tissue in 18 cases (15 papillomas). The difference of ductal obstruction between these groups was found to be highly significant in two-sided Fisher's exact test (p < 0.001). Because of the clear association with benign lesions, benign lesions showing ductal obstruction were characterized as true positive findings. Therefore, following diagnostic parameters were calculated: sensitivity 15.4%, specificity 99.0%, LR+ 15.3, LR- 0.9. Discussion: If ductal obstruction is found to be positive, the associated lesion is most likely benign. Therefore, though a rare finding, this descriptor should be taken into account for improved lesion differentiation.

    2013-01-01

    Full Text Available Introduction. Developments in immunological and quantitative real-time PCR-based analysis have enabled the detection, enumeration, and characterization of circulating tumor cells (CTCs. It is assumed that the detection of CTCs is associated with cancer, based on the finding that CTCs can be detected in all major cancer and not in healthy subjects or those with benign disease. Methods and Patients. Consecutive men, with suspicion of prostate cancer, had blood samples taken before prostate biopsy; mononuclear cells were obtained using differential gel centrifugation and CPCs detecting using anti-PSA immunocytochemistry. Positive samples underwent further classification with anti-P504S. Results. 329 men underwent prostate biopsy; of these men 83 underwent a second biopsy and 44 a third one. Of those with a biopsy negative for cancer, 19/226 (8.4% had CPCs PSA (+ P504S (− detected at first biopsy, 6/74 (8.1% at second biopsy, and 5/33 (15.2% at third biopsy. Men with cancer-positive biopsies did not have PSA (+ P504S (− CPCs detected. These benign cells were associated with chronic prostatitis. Conclusions. Patients with chronic prostatitis may have circulating prostate cells detected in blood, which do not express the enzyme P504S and should be thought of as benign in nature.

    Full Text Available Objective: This study aims to investigate the role of IGF-1 in the development of nodular thyroid disease. Material and Methods: A total number of 100 consecutive patients operated for nodular thyroid disease in our institution were included in this prospective study. In addition to classical pathological examinations, nodules and extranodular healthy tissues were sampled and immunochemically stained for IGF-1. The materials were independently evaluated using an Allred Scoring System ranging from 0 to 8. If the score was ≥1, the tissue was accepted as IGF-1 positive.Results: IGF-1 positivity was observed in 88% and 58% of the samples obtained from nodules and extranodular healthy tissues, respectively. Allred 8-unit scores were higher in benign nodules (n=89; 4.1±2.3 and papillary carcinomas (n=7; 6.7±1.3, than in extranodular healthy tissues in the same patients (2.3±2.3 and 3.3±1.9, respectively; and higher in papillary carcinomas than in benign nodules, when the scores were compared to each other (p<0.01 for all comparisons. Conclusions: Allred 8-unit scores for IGF-1 increase in the presence of benign thyroid nodules, papillary cancer. The results of our study support the findings of previous studies demonstrating the role of IGF-1 in the development of thyroidal nodules.

    Full Text Available Benign isolated abducens palsy is a self-improving clinical entity characterized by esotropia and diplopia led by the deficiency of abduction, and accompanied by no other neurological findings. The entity may occur after experiencing minor fever episodes, viral infection. The pathophysiological mechanism of cellular injury remains unclear. Hypotheses involve damage arising from autoimmune mediation or direct viral invasion causing demyelination, localized arteritis or genetic predisposition, which could increase susceptibility to such nerve palsies. Diagnosed with benign isolated abducens palsy, a 19-month-old girl infant admitted to our outpatient clinic with an acute onset of esotropia in the right eye developing two weeks after the vaccination of diphtheria, acellular pertussis, tetanus, inactivated polio and Haemophilus influenzae type b (DTPa-IP-Hib was presented in this report.

    1980-05-01

    The authors formed a Mouth Clinic at Sunnybrook Hospital in 1973 since when there have been 3025 patient visits. Those patients with chronic ulceration present a challenge, the diagnosis sometimes being difficult and therapy not rapidly effective. The differential diagnosis includes lichen planus, pemphigus vulgaris, benign mucous membrane pemphigoid, discoid lupus erythematosus, erythema multiforme, aphthous ulcers, Behcets disease, periadenitis mucosa necrotica recurrens, specific infections and iatrogenic causes. It is possible to reach a definite diagnosis in virtually every case by means of a good history and careful clinical examination supplemented by biopsies and in some cases direct and indirect immunofluorescent studies. Treatment emphasizes scrupulous attention to oral hygiene with baking soda mouthwashes and careful teeth cleaning to minimize the accumulation of dental plaque. Specific therapy includes topical steroids in lichen planus, intra muscular gold in benign mucous membrane pemphigoid, a previously unreported treatment which considerably improved seven out of ten patients, and tetracycline mouthwashes in aphthous ulcers.

  16. MR imaging of benign pediatric soft-tissue tumors

    International Nuclear Information System (INIS)

    This paper reports twenty-five children with 27 clinically benign soft-tissue tumors evaluated with MR imaging. These lesions were indolent and seemed nonaggressive at palpation. Prior to surgery, and attempt was made to predict the histologic findings, estimate the tumor dimensions and invasiveness, and assess the relationship of the mass to the neurovascular structures. Diagnoses included lipomas, hemangiolymphangiomas, neurofibromas, fibromatosis, ganglion and synovial cysts, fibromas, posttraumatic subcutaneous fat necrosis, and muscle hernias. MR imaging was performed with a 1.5-T system. T1-weighted (spin echo [SE] 600/20 [repetition time msec/echo time msec]) and T2-weighted (Se 2,000/20, 80) images were obtained through each lesion in a variety of planes. In most cases, tumor signal characteristics and tumor behavior enabled prediction of the histologic findings. MR imaging is an efficacious technique for evaluation of benign soft-tissue tumors prior to surgical therapy

    Although ethanol ablation has been successfully used to treat cystic thyroid nodules, this procedure is less effective when the thyroid nodules are solid. Radiofrequency (RF) ablation, a newer procedure used to treat malignant liver tumors, has been valuable in the treatment of benign thyroid nodules regardless of the extent of the solid component. This article reviews the basic physics, techniques, applications, results, and complications of thyroid RF ablation, in comparison to laser ablation.

    2008-01-01

    Objective: This prospective randomized clinical trial was conducted to evaluate the necessity of drainage after total thyroidectomy or lobectomy for benign thyroidal disorders. Methods: A total of 116 patients who underwent total thyroidectomy or lobectomy for benign thyroidal disorders were randomly allocated to be drained or not. Operative and postoperative outcomes including operating time, postoperative pain assessed by visual analogue scale (VAS), total amount of intramuscular analgesic administration, hospital stay, complications, necessity for re-operation and satisfaction of patients were all assessed. Results: The mean operating time was similar between two groups (the drained and non-drained groups). The mean VAS score was found to be significantly low in the non-drained group patients in postoperative day (POD) 0 and POD 1. The mean amount of intramuscular analgesic requirement was significantly less in the non-drained group. One case of hematoma, two cases of seroma and three cases of transient hypoparathyroidism occurred in the non-drained group, whereas one case of hematoma, two cases of seroma, two cases of wound infections and two cases of transient hypoparathyroidism occurred in the drained group. No patient needed re-operation for any complication. The mean hospital stay was significantly shorter and the satisfaction of patients was superior in the non-drained group. Conclusion: These findings suggest that postoperative complications cannot be prevented by using drains after total thyroidectomy or lobectomy for benign thyroid disorders. Furthermore, the use of drains may increase postoperative pain and the analgesic requirement, and prolong the hospital stay. In the light of these findings, the routine use of drains might not be necessary after thyroid surgery for benign disorders.

    Purpose: To evaluate the outcomes of argon laser photoablation of benign conjunctival pigmented nevi with different clinical presentations. Patients and Methods: This interventional case series was conducted between July 2014 and January 2015. Patients presenting with benign conjunctival nevi were included. Data were collected on the clinical features at presentation, argon laser photoablation, and follow-up at 8 and 24 weeks. Postoperative photography allowed recording of the success of each case and the overall success rate. Complete removal of conjunctival pigments was considered an absolute success. Partial pigmentation requiring repeat laser treatment was considered a qualified success. Results: There were 14 eyes (four right eyes and ten left eyes) with benign pigmented conjunctival nevi. There were three males and eight females in the study sample. The median age was 36 (25% percentile: 26 years). Three patients had bilateral lesions. The nevi were located temporally in nine eyes, nasally in three eyes, and on the inferior bulbar conjunctiva in two eyes. The mean horizontal and vertical diameters of nevi were 5 ± 2 mm and 4 ± 2.7 mm, respectively. The mean follow-up period was 5 months. Following laser treatment, no eyes had subconjunctival hemorrhage, infection, scarring, neovascularization, recurrence, or corneal damage. The absolute success rate of laser ablation was 79%. Three eyes with elevated nevi had one to three sessions of laser ablation resulting in a qualified success rate of 100%. Conclusions: Argon laser ablation was a safe and effective treatment for the treatment of selective benign pigmented conjunctival nevi in Arab patients. PMID:27555708

    There is increasing evidence of causal relation between benign prostatic hyperplasia (BPH) and erectile dysfunction (ED). BPH appears to have a negative impact on sexual function. Drugs commonly used for the treatment of BPH (i.e. alphablockers, 5-alpha reductase inhibitors) may cause retrograde ejaculation, ED and reduced libido. Physicians should be aware of these adverse events and inform their patients accordingly. Conversely, phosphodiestease-5-inhibitors may have a beneficial effect on BPH symptoms. PMID:20235043

    Between February 1981 and June 1984, 15 patients with benign biliary strictures were treated with percutaneous transhepatic balloon dilatation. Three of these patients had received liver transplants. The treatment began with a course of balloon dilatation therapy, after which a stent catheter was left across the stricture. Six weeks later, after duct patency had been shown by cholangiography, the stent catheter was removed from all but two patients, both of whom had intrahepatic sclerosing ch...

  19. Solitary pulmonary nodule. Differentiating benign from malignant nodule, CT-bronchoscopic correlation, and usefulness of artificial neural networks on CT

    International Nuclear Information System (INIS)

    The objective of this study was to evaluate the useful CT finding for differentiating benign from malignant pulmonary nodule and for CT-bronchoscopic correlation, and to evaluate the usefulness of artificial neural networks (ANN). Sixty-six patients of solitary pulmonary nodule smaller than 3 cm were evaluated for differential diagnosis and CT-bronchoscopic correlation. One hundred fifty-five patients of solitary pulmonary nodule smaller than 3 cm were evaluated for ANN analysis. In lung cancers, air bronchogram/bronchiologram, grossly irregular margin, and the involvement of pulmonary vein were common, while straight or inward concave margin and satellite lesions were predominantly seen in benign nodules. The positive bronchus sign on CT was useful in predicting the success of transbronchial biopsy. The average Az value for all radiologists increased with the use of the ANN output. (author)

    Full Text Available BACKGROUND: Telomerase is a reverse transcriptase enzyme that synthesizes telomeric DNA on chromosome ends. The enzyme is important for the immortalization of cancer cells because it maintains the telomeres. METHODS: Telomerase activity (TA was measured by fluorescence-based telomeric repeat amplification protocol (FTRAP assay in prostate carcinoma and benign prostatic hyperplasia (BPH. RESULTS: TA was present in 91.4% of 70 prostate cancers, 68.8% of 16 prostatic intraepithelial neoplasia (PIN, 43.3% of 30 BPH*, 21.4% of 14 atrophy and 20% of 15 normal samples adjacent to tumor. There was not any significant correlation between TA, histopathological tumor stage or gleason score. In contrast to high TA in the BPH* tissue from the cancer-bearing gland, only 6.3% of 32 BPH specimens from patients only diagnosed with BPH were telomerase activity-positive. CONCLUSIONS: These results indicate that TA is present in most prostate cancers. The high rate of TA in tissue adjacent to tumor may be attributed either to early molecular alteration of cancer that was histologically unapparent, or to the presence of occult cancer cells. Our findings suggest that the re-expression of telomerase activity could be one step in the transformation of BPH to PIN. KEY WORDS: Telomerase activity, prostate cancer, prostatic intraepithelial neoplasia, benign prostatic hyperplasia.

    Full Text Available Leiomyosarcoma (LMS is a malignant, soft-tissue tumor for which few effective therapies exist. Previously, we showed that there are three molecular subtypes of LMS. Here, we analyzed genes differentially expressed in each of the three LMS subtypes as compared to benign leiomyomas and then used the Connectivity Map (cmap to calculate enrichment scores for the 1309 cmap drugs in order to identify candidate molecules with the potential to induce a benign, leiomyoma-like phenotype in LMS cells. 11 drugs were selected and tested for their ability to inhibit the growth of three human LMS cell lines. We identified two drugs with in vitro efficacy against LMS, one of which had a strongly negative enrichment score (Cantharidin and the other of which had a strongly positive enrichment score (MG-132. Given MG-132’s strong inhibitory effect on LMS cell viability, we hypothesized that LMS cells may be sensitive to treatment with other proteasome inhibitors and demonstrated that bortezomib, a clinically-approved proteasome inhibitor not included in the original cmap screen, potently inhibited the viability of the LMS cell lines. These findings suggest that systematically linking LMS subtype-specific expression signatures with drug-associated expression profiles represents a promising approach for the identification of new drugs for LMS.

  2. Gamma knife radiosurgery for benign cavernous sinus tumors. Treatment concept and outcomes in 120 cases

    International Nuclear Information System (INIS)

    Availability of modern computer-aided robotized devices, such as the Automatic Positioning System (APSTM; Elekta Instruments AB, Stockholm, Sweden) and PerfexionTM (Elekta Instruments AB), allowed us to develop the original concept of robotic gamma knife microradiosurgery, which is based on the very precise irradiation of the lesion with regard to conformity and selectivity; intentional avoidance of the excessive irradiation of functionally-important anatomical structures, particularly cranial nerves, located both within and in the vicinity of the target; and delivery of sufficient irradiation energy to the tumor with the intention to attain lesion shrinkage, while keeping the marginal dose sufficiently low for prevention of possible complications. The results of such treatment strategy were evaluated retrospectively in 120 patients with benign cavernous sinus neoplasms (pituitary adenomas, meningiomas, schwannomas, and hemangiomas), who were followed up from 24 to 78 months (mean 47 months) after radiosurgery. Tumor growth control and shrinkage rates were 98% and 68%, respectively. More than 50% volume reduction was noted in 25% of lesions. The most prominent volumetric tumor response was observed in hemangiomas, followed by schwannomas, pituitary adenomas, and meningiomas. Treatment-related complications were marked in 7% of cases, and were mainly related to transient isolated cranial neuropathy appearing within several months after radiosurgery. Major morbidity was limited to one patient (0.8%). Application of microradiosurgical treatment principles provides effective and safe management of benign cavernous sinus tumors and is associated with high probability of lesion shrinkage and minimal risk of complications.

    Breast cancer is one of the most common malignancies in women and the incidence has been increasing. Cytology plays a very important role not only in the diagnosis of breast lesions, but also in keeping the benign-to-malignant biopsy ratio low, so that unnecessary surgery is not performed. A fundamental feature of a benign aspirate is the presence of a dual population of ductal epithelial cells (variable within limits, but cohesive and orderly) and myoepithelial cells (naked, bipolar nuclei). Several cytologic features must be assessed to make the diagnosis of malignancy, including high cellularity, cell dissociation, large nuclear and cell size, cell pleomorphism, intracytoplasmic lumens (containing mucin), irregular nuclear margin, coarse chromatinic pattern, prominent nucleoli, and the presence of abnormal mitoses. Other criteria of lesser importance include necrosis, absence of myoepithelial cells and intranuclear inclusions. However, breast carcinomas do not always show every feature of malignancy. The well-differentiated or low-grade carcinomas are often difficult to differentiate from benign cells. It may be helpful to consider the clinical and radiological findings. We reported here, typical neoplastic lesions of the breast by correlating cytological with histopathological features. PMID:10442036

    Benign esophageal lesions occur in various diseases. Barium studies are useful for the evaluation of mucosal surface lesions but provide little information about the extramucosal extent of disease. Computed tomography and magnetic resonance imaging, on the other hand, permit the assessment of wall thickness, mediastinal involvement, adjacent lymphadenopathy, and distant spread. In diseases such as fibrovascular polyps, duplication cysts, scleroderma, trauma, caustic esophagitis, hiatal hernia, esophageal diverticulum, achalasia, and paraesophageal varices, the findings of imaging studies are specific, obviating the need for further invasive diagnostic work-up. The advent of helical computed tomography and its volume data set allows the acquisition of multiplanar images, and magnetic resonance imaging is useful both for this and for tissue characterization. Thus, multiplanar cross-sectional imaging further extends the role of imaging modalities to the evaluation of benign esophageal lesions. Through an awareness of the multiplanar cross-sectional appearances of various benign esophageal lesions, the radiologist can play an important role in the detection, diagnosis, further diagnostic planning, and treatment of the diseases in which they occur.

    Full Text Available We provide systematic evidence for the range and importance of hedonic reversals as a major source of pleasure, and incorporate these findings into the theory of benign masochism. Twenty-nine different initially aversive activities are shown to produce pleasure (hedonic reversals in substantial numbers of individuals from both college student and Mechanical Turk samples. Hedonic reversals group, by factor analysis, into sadness, oral irritation, fear, physical activity/exhaustion, pain, strong alcohol-related tastes, bitter tastes, and disgust. Liking for sad experiences (music, novels, movies, paintings forms a coherent entity, and is related to enjoyment of crying in response to sad movies. For fear and oral irritation, individuals also enjoy the body's defensive reactions. Enjoyment of sadness is higher in females across domains. We explain these findings in terms of benign masochism, enjoyment of negative bodily reactions and feelings in the context of feeling safe, or pleasure at ``mind over body''. In accordance with benign masochism, for many people, the favored level of initially negative experiences is just below the level that cannot be tolerated.

    To evaluate the role of fractionated stereotactic radiotherapy (FSRT) in the management of benign brain tumors, we reviewed the clinical, and radiographic responses of patients treated. Between March 1996 and March 2002, 36 patients with benign brain tumors were treated by FSRT. The pathological diagnoses consisted of pituitary adenomas (12 patients), craniopharyngiomas (5 patients), meningiomas (10 patients), and acoustic neurinomas (9 patients). Radiotherapy doses of 25 to 35 Gy (3-6 Gy/fraction, 5-10 fractions) were prescribed to the 85-90% isodose line, depending upon the location, size and volume of the tumors. The median clinical and radiographical followup periods were 31 [range, 2-74) and 21 (range, 4-56) months, respectively. In the 35 patients that could be evaluated for their clinical response, 13 (37.1%) were considered improved, 16 (45.7%) stable and 6 (17.2%) worse. Of the 33 patients who had radiographic studies, tumor shrinkage was noted in 17 (51.5%), tumor stabilization in 13 (39.4%), and tumor progression in 3 (9,1%). Of the 17 tumor shrinkage patients, 7 [21.2%) showed a complete response, Acute radiation-induced complications occurred in 11 (30.6%) patients. FSRT is considered a safe and effective treatment method for benign brain tumors but large numbers of patients, with relatively long follow-up periods are needed to assess the exact role or effect of FSRT.

    AIM: To elucidate the mechanism of restenosis following balloon dilation of benign esophageal stenosis.METHODS: A total of 49 rats with esophageal stenosis were induced in 70 rats using 5 ml of 50 % sodium hydroxide solution and the double-balloon method, and an esophageal restenosis (RS) model was developed by esophageal stenosis using dilation of a percutaneous transluminal coronary angioplasty (PTCA) balloon catheter. These 49 rats were divided into two groups: rats with benign esophageal stricture caused by chemical burn only (control group, n=21) and rats with their esophageal stricture treated with balloon catheter dilation (experimental group, n=28). Imaging analysis and immunohistochemistry were used for both quantitative and qualitative analyses of esophageal stenosis and RS formation in the rats, respectively.RESULTS: Cross-sectional areas and perimeters of the esophageal mucosa layer, muscle layer, and the entire esophageal layers increased significantly in the experimental group compared with the control group. Proliferating cell nuclear antigen (PCNA) was expressed on the 5th day after dilation, and was still present at 1 month. Fibronectin (FN)was expressed on the 1st day after dilation, and was still present at 1 month.CONCLUSION: Expression of PCNA and FN plays an important role in RS after balloon dilation of benign esophageal stenosis.

    To screen and evaluate protein biomarkers for the detection of gliomas (Astrocytoma grade Ⅰ-Ⅳ) from healthy individuals and gliomas from brain benign tumors by using surface enhanced laser desorption/ionization time of flight mass spectrometry (SELDI-TOF-MS) coupled with an artificial neural network (ANN) algorithm. SELDI-TOF-MS protein fingerprinting of serum from 105 brain tumor patients and healthy individuals, included 28 patients with glioma (Astrocytoma Ⅰ-Ⅳ), 37 patients with brain benign tumor, and 40 age-matched healthy individuals. Two thirds of the total samples of every compared pair as training set were used to set up discriminating patterns, and one third of total samples of every compared pair as test set were used to cross-validate; simultaneously, discriminate-cluster analysis derived SPSS 10.0 software was used to compare Astrocytoma grade Ⅰ-Ⅱ with grade Ⅲ-Ⅳ ones. An accuracy of 95.7%, sensitivity of 88.9%, specificity of 100%, positive predictive value of 90% and negative predictive value of 100% were obtained in a blinded test set comparing gliomas patients with healthy individuals; an accuracy of 86.4%, sensitivity of 88.9%, specificity of 84.6%, positive predictive value of 90% and negative predictive value of 85.7% were obtained when patient's gliomas was compared with benign brain tumor. Total accuracy of 85.7%, accuracy of grade Ⅰ-Ⅱ Astrocytoma was 86.7%, accuracy ofⅢ-Ⅳ Astrocytoma was 84.6% were obtained when grade Ⅰ-Ⅱ Astrocytoma was compared with grade Ⅲ-Ⅳ ones (discriminant analysis). SELDI-TOF-MS combined with bioinformatics tools, could greatly facilitate the discovery of better biomarkers. The high sensitivity and specificity achieved by the use of selected biomarkers showed great potential application for the discrimination of gliomas patients from healthy individuals and glioma from brain benign tumors.

    Full Text Available Abstract The most common semiquantitative method of evaluation of pulmonary lesions using 18F-FDG PET is FDG standardized uptake value (SUV. An SUV cutoff of 2.5 or greater has been used to differentiate between benign and malignant nodules. The goal of our study was to investigate the correlation between the size of pulmonary nodules and the SUV for benign as well as for malignant nodules. Methods Retrospectively, 173 patients were selected from 420 referrals for evaluation of pulmonary lesions. All patients selected had a positive CT and PET scans and histopathology biopsy. A linear regression equation was fitted to a scatter plot of size and SUVmax for malignant and benign nodules together. A dot diagram was created to calculate the sensitivity, specificity, and accuracy using an SUVmax cutoff of 2.5. Results The linear regression equations and (R2s as well as the trendlines for malignant and benign nodules demonstrated that the slope of the regression line is greater for malignant than for benign nodules. Twenty-eight nodules of group one (≤ 1.0 cm are plotted in a dot diagram using an SUVmax cutoff of 2.5. The sensitivity, specificity, and accuracy were calculated to be 85%, 36% and 54% respectively. Similarly, sensitivity, specificity, and accuracy were calculated for an SUVmax cutoff of 2.5 and found to be 91%, 47%, and 79% respectively for group 2 (1.1–2.0 cm; 94%, 23%, and 76%, respectively for group 3 (2.1–3.0 cm; and 100%, 17%, and 82%,, respectively for group 4 (> 3.0 cm. The previous results of the dot diagram indicating that the sensitivity and the accuracy of the test using an SUVmax cutoff of 2.5 are increased with an increase in the diameter of pulmonary nodules. Conclusion The slope of the regression line is greater for malignant than for benign nodules. Although, the SUVmax cutoff of 2.5 is a useful tool in the evaluation of large pulmonary nodules (> 1.0 cm, it has no or minimal value in the evaluation of small

    Increase of intracellular positive ions (mainly Na(+)) indicates greater possibility of cell malignancy. The present study investigated the correlation between the Na(+) micro-current value (MCV) and tissue characteristics (normal, benign or malignant). 346 tissue samples have been detected within 30 min after surgical isolation by Na(+) detector. MCV in 102 malignant tumor was significantly higher than that in benign/borderline tumor or normal tissue (33.3 ± 8.9 μA vs. 24.4 ± 8.6 μA and 14.0 ± 4.0 μA, p detector and pathological examination was different in tissues from different organs or systems, which was high in pancreas, bile duct system, gastrointestinal system, esophagus, breasts, lungs, nose &throat and thyroids, but poor in urinary tissue. The overall coincidence rate was 83.1% (108/130) between Na(+) detector and pathological examination. The sensitivity and specificity of correct diagnosis by Na(+) detector was 83.3% (70/84) and 82.6% (38/46), respectively. This new modality may have diagnostic potential in complementing frozen examination in differentiating malignant tumor from benign or normal tissue, justifying tumor metastatic scope and confirming surgical margin.

    Full Text Available Breast cancer is the primary and most common disease found in women which causes second highest rate of death after lung cancer. The digital mammogram is the X-ray of breast captured for the analysis, interpretation and diagnosis. According to Breast Imaging Reporting and Data System (BIRADS benign and malignant can be differentiated using its shape, size and density, which is how radiologist visualize the mammograms. According to BIRADS mass shape characteristics, benign masses tend to have round, oval, lobular in shape and malignant masses are lobular or irregular in shape. Measuring regular and irregular shapes mathematically is found to be a difficult task, since there is no single measure to differentiate various shapes. In this paper, the malignant and benign masses present in mammogram are classified using Hue, Saturation and Value (HSV weight function based statistical measures. The weight function is robust against noise and captures the degree of gray content of the pixel. The statistical measures use gray weight value instead of gray pixel value to effectively discriminate masses. The 233 mammograms from the Digital Database for Screening Mammography (DDSM benchmark dataset have been used. The PASW data mining modeler has been used for constructing Neural Network for identifying importance of statistical measures. Based on the obtained important statistical measure, the C5.0 tree has been constructed with 60-40 data split. The experimental results are found to be encouraging. Also, the results will agree to the standard specified by the American College of Radiology-BIRADS Systems.

  16. Radiation for not-so-benign coronary artery disease

    International Nuclear Information System (INIS)

    The role of radiation therapy in the treatment of malignant disease has long been accepted. More limited application of radiation in the treatment of benign conditions has been proven but generally not pursued. On the centennial anniversary of radiation therapy, a promising, but as yet unproved, application of radiation for treatment of benign vascular disease has become an exciting field of research, speculation, and controversy. This panel presentation will discuss the rationales and dilemmas of applying radiation in the prevention of arterial restenosis after therapeutic intervention. Coronary artery bypass grafting and more recently coronary angioplasty have become accepted, effective therapies to reverse significant coronary stenosis, and thereby benefit the majority of patients with coronary artery disease. However, a large proportion of patients will suffer restenosis in spite of optimal conventional therapy. The search for a means to prevent such restenosis has been partially successful by therapies, and even engineering intravascular devices. In spite of these efforts, a significant number of patients will fail today's conventional therapy and suffer arterial restenosis. Fibroblast myointimal proliferation is felt to be a major element in this restenosis process. Clinical experience shows that radiation inhibits other similar benign fibroblast proliferative processes such as keloid scar formation and heterotopic ossification. Radiation is now being considered as a means to inhibit myointimal fibroblast proliferation and hopefully prevent attendant arterial restenosis as well. This has catalyzed various animal model investigations that have shown significant arteries. Promising results in the animal model and in very early human institutional trials. These trials are designed to determine if radiation is truly effective and can be safely delivered to prevent restenosis in diseased human arteries. This panel discussion will provide a firm basic science and

  17. MR imaging of edema accompanying benign and malignant bone tumors

    International Nuclear Information System (INIS)

    To evaluate the incidence, quantity, and presentation of intra- and extraosseous edema accompanying benign and malignant primary bone lesions, the magnetic resonance (MR) studies of 63 consecutive patients with histologically proven primary bone tumors were reviewed. MR scans were assessed for the presence and quantity of marrow and soft tissue edema and correlated with preoperative findings, resected specimens and follow-up data. The signal intensity and enhancement of tumor and edema prior to and after intravenous administration (if any) of gadolinium-labled diethylene triamine pentaacetate (Gd-DTPA) was analyzed. Marrow edema was encountered adjacent to 8 of 39 maglinant tumors and 14 of 24 benign lesions. Soft tissue edema was found accompanying 28 of 39 malignancies and 10 of 24 benign disorders. On enhanced T1-weighted MR images tumor and edema were difficult to differentiate. Tumor inhomogeneity made this differentiation easier on T2-weighted sequences. In 36 patients the contrast medium Gd-DTPA was used. Edema was present in 27 of these patients and the respective enhancement of tumor and edema could be compared. Edema always enhanced homogeneously, and in most cases it enhanced to a similar degree as or more than tumor. Marrow and, more specifically, soft tissue edema is a frequent finding adjacent to primary bone tumors. The mere presence and quantity of marrow and soft tissue edema are unreliable indicators of the biologic potential of a lesion. Unenhanced MR scans cannot always differentiate between tumor and edema, but the administration of Gd-DTPA is of assistance in differentiating tumor from edema. Awareness of marrow and/or soft tissue edema adjacent to bone lesions is of importance because edema can be a pitfall in the diagnostic work-up and staging prior to biopsy or surgery. (orig.)

    Objective: To determine the frequency and severity of facial nerve dysfunction following surgery for benign parotid gland tumours. Study Design: A case series. Place and Duration of Study: ENT Department, Karachi Medical and Dental College and Abbasi Shaheed Hospital and Ziauddin University Hospital, from 1990 to 2010. Methodology: Data was collected of all patients who were surgically managed for benign parotid tumours from 1990 to 2010. Data was reviewed for presentation of tumour, age and gender of the patient, site of tumour, nature and morphology of the tumour, primary or recurrent, surgical procedure adopted and the complications of the surgery especially the facial nerve dysfunction, its severity, complete or partial paresis and transient or permanent and time of recovery. Results were described as frequency percentages. Results: Out of 235 patients, 159 (67.65%) were female and 76 (32.35%) were male. Age ranged from 18 to 70 years. Pleomorphic adenoma was the most common tumour (n=194, 82.6%), followed by Warthin's tumour. Superficial parotidectomy was done in 188 cases and extended parotidectomy in 47 cases. In the immediate postoperative period facial nerve function was normal in 169 (72%) patients and nerve dysfunction was observed in 66 (28%) patients. Complete paresis involving all the branches of facial nerve was seen in 25 (10.6%) patients and 41 (17.4%) patients were having incomplete dysfunction. Of these, 62 (26.3%) recovered and 04 (1.7%) had permanent facial nerve dysfunction. Marginal mandibular branch of facial nerve was involved in 57 (86.3%) cases. Conclusion: The frequency of temporary and permanent facial nerve dysfunction was 26.3% and 1.7% respectively in 235 consecutive parotidectomies for benign parotid gland tumours. Higher frequency of facial nerve dysfunction was found in recurrent and deep lobe tumours. (author)

    FDG PET is good diagnostic tool for oncologic staging work-up, but it has been reported that PET has a difficult in differential diagnosis between some benign diseases and malignancy. We would report benign lung lesion of FDG PET in our center based on pathologic findings. 107 cases of lung cancer which performed lung surgery and 2 cases of pneumoconiosis which performed PCNA were analyzed from Dec 1997 to Mar 2000. Obstructive pneumonitis were proven pathologically in seven cases and hypermetabolic area were seen where proven as obstructive pneumonitis in five of seven cases. Wedge shaped peripherally increased metabolic area with irregular hypermetabolism were seen in 4 of 5 cases. Collapse was proven in 4 cases and only in one case, faintly increased metabolic area was seen in PET where proven as collapse. Radiation fibrosis was proven in one case, which show hypermetabolism in pleural space limited to previous RT field and Empyema with lung cancer was proven in one case, which show increased metabolism in ipsilateral pleural space with focal hypermetabolism. Pulmonary tbc was proven in one case, which show hypermetabolic lesion with central necrosis. Pneumoconiosis were diagnosed in two cases, one of them was combined with lung cancer and the other case was combined with lung cancer and pulmonary tbc at the same time, showing difficult in distinguish scattered small hypermetabolic lesions by pneumoconiosis from metastasis of lung cancer or pulmonary tbc. FDG PET has a difficult in differential diagnosis between some benign disease and malignancy, and more variant and numerous case experience is expected to give help in improving of diagnostic efficiency

  20. Proton Stereotactic Radiosurgery for the Treatment of Benign Meningiomas

    International Nuclear Information System (INIS)

    Purpose: Given the excellent prognosis for patients with benign meningiomas, treatment strategies to minimize late effects are important. One strategy is proton radiation therapy (RT), which allows less integral dose to normal tissue and greater homogeneity than photon RT. Here, we report the first series of proton stereotactic radiosurgery (SRS) used for the treatment of meningiomas. Methods and Materials: We identified 50 patients with 51 histologically proven or image- defined, presumed-benign meningiomas treated at our institution between 1996 and 2007. Tumors of <4 cm in diameter and located ≥2 mm from the optic apparatus were eligible for treatment. Indications included primary treatment (n = 32), residual tumor following surgery (n = 8), and recurrent tumor following surgery (n = 10). The median dose delivered was 13 Gray radiobiologic equivalent (Gy[RBE]) (range, 10.0-15.5 Gy[RBE]) prescribed to the 90% isodose line. Results: Median follow-up was 32 months (range, 6-133 months). Magnetic resonance imaging at the most recent follow-up or time of progression revealed 33 meningiomas with stable sizes, 13 meningiomas with decreased size, and 5 meningiomas with increased size. The 3-year actuarial tumor control rate was 94% (95% confidence interval, 77%-98%). Symptoms were improved in 47% (16/ 34) of patients, unchanged in 44% (15/34) of patients, and worse in 9% (3/34) of patients. The rate of potential permanent adverse effects after SRS was 5.9% (3/51 patients). Conclusions: Proton SRS is an effective therapy for small benign meningiomas, with a potentially lower rate of long-term treatment-related morbidity. Longer follow-up is needed to assess durability of tumor control and late effects.
