    Full Text Available Benign paroxysmal positional vertigo (BPPV is a syndrome characterized by transient episodes of vertigo in association with rapid changes in head position in Dix-Halpike Maneuver. This kind of vertigo is thought to be caused by migration of otoconial debris into canals other than the posterior canal, such as the anterior or lateral canals. It is also theoretically possible for many aberrant patterns of BPPV to occur from an interaction of debris in several canals, location of debris within the canal, and central adaptation patterns to lesions. The symptoms of BPPV are much more consistent with free-moving densities (canaliths in the posterior SCC rather than fixed densities attached to the cupula. While the head is upright, the particles sit in the PSC at the most gravity-dependent position. The best method to induce and see vertigo and nystagmus in BPPV of the lateral semicircular canal is to rotate head 90°while patient is in the supine position, nystagmus would appear in the unaffected side weaker but longer than the affected side. canal paresis has been described in one third of the patients with BPPV. Adaptation which is one of the remarkable features of BPPV in PSC is rarely seen in LSC. Rotations of 270° or 360° around the yaw axis (the so-called barbecue maneuver toward the unaffected ear are popular methods for the treatment of geotropic HC-BPPV. These maneuvers consist of sequential head turning of 90° toward the healthy side while supine. With these maneuvers, the free-floating otoconial debris migrates in the ampullofugal direction, finally entering the utricle through the nonampullated end of the horizontal canal. This kind of vertigo recovers spontaneously more rapidly and suddenly.

    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.

  9. Benign Paroxysmal Positional Vertigo: An Integrated Perspective

    Full Text Available Benign paroxysmal positional vertigo (BPPV, the most common cause of dizziness, occurs in all age groups. It presents with vertigo on head movement, but in older patients presentation may be typical and thus accounting for a low recognition rate in the primary care setting. It may be recurrent in up to 50% of cases. BPPV is associated with displacement of fragments of utricular otoconia into the semicircular canals, most commonly the posterior semicircular canal. Otoconia are composed of otoconin and otolin forming the organic matrix on which calcium carbonate mineralizes. Otoconia may fragment with trauma, age, or changes in the physiology of endolymph (e.g., pH and calcium concentration. Presentation varied because otoconia fragments can be displaced into any of the semicircular canals on either (or both side and may be free floating (canalolithiasis or attached to the cupula (cupulolithiasis. Most cases of BPPV are idiopathic, but head trauma, otologic disorders, and systemic disease appear to be contributory in a subset. Positional maneuvers are used to diagnose and treat the majority of cases. In rare intractable cases surgical management may be considered. A strong association with osteoporosis suggests that idiopathic BPPV may have diagnostic and management implications beyond that of a purely otologic condition.

    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;}

    2016-07-01

    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

    Full Text Available Background and Aim: Since utricle is the main damaged organ in benign paroxysmal positional vertigo (BPPV, ocular vestibular evoked myogenic potential (oVEMP may be an appropriate method to evaluate the utricule dysfunction and the effect of disease recurrence rate on it. This study aimed to record myogenic potential in patients with benign paroxysmal positional vertigo.Methods: In a cross-sectional study, ocular myogenic potential was recorded in 25 healthy subjects and 20 patients with benign paroxysmal positional vertigo using 500 Hz-tone bursts (95 dB nHL.Results: In the affected ear, mean amplitude was lower and mean threshold was higher than those in the unaffected ear and in the normal group (p<0.05. Mean amplitude asymmetry ratio of patients was more than the healthy subjects (p0.05. Frequencies of abnormal responses in the affected ears were higher than in unaffected ears and in the normal group (p<0.05. Furthermore, the patients with recurrent vertigo showed more abnormalities than the patients with non-recurrent (p=0.030.Conclusion: In the recurrent benign paroxysmal positional vertigo, ocular vestibular evoked myogenic potential showed more damage in the utricle, suggesting this response could be used to evaluate the patients with benign paroxysmal positional vertigo.

    For horizontal canal benign paroxysmal positional vertigo, determination of the pathologic side is difficult and based on many physiological assumptions. This article reports findings on a patient who had one dysfunctional inner ear and who presented with horizontal canal benign paroxysmal positional vertigo, giving us a relatively pure model for observing nystagmus arising in a subject in whom the affected side is known a priori. It is an interesting human model corroborating theories of nystagmus generation in this pathology and also serves to validate Ewald's second law in a living human subject.

This study was performed to identify and validate useful questions for suspecting a diagnosis of benign paroxysmal positional vertigo (BPPV.Methods: Construction and validation of a disease prediction model was performed at the outpatient clinic in the Department of General Medicine of Chiba University Hospital. Patients with dizziness were enrolled (145 patients for construction of the disease prediction model and 61 patients for its validation. This study targeted BPPV of the posterior semicircular canals only with a positive Dix–Hallpike test (DHT + BPPV to avoid diagnostic ambiguity. Binomial logistic regression analysis was performed to identify the items that were useful for diagnosis or exclusion of DHT + BPPV.Results: Twelve patients from the derivation set and six patients from the validation set had DHT + BPPV. Binomial logistic regression analysis selected a "duration of dizziness ≤15 seconds" and "onset when turning over in bed" as independent predictors of DHT + BPPV with an odds ratio (95% confidence interval of 4.36 (1.18–16.19 and 10.17 (2.49–41.63, respectively. Affirmative answers to both questions yielded a likelihood ratio of 6.81 (5.11–9.10 for diagnosis of DHT + BPPV, while negative answers to both had a likelihood ratio of 0.19 (0.08–0.47.Conclusion: A "duration of dizziness ≤15 seconds" and "onset when turning over in bed" were the two most important questions among various historical features of BPPV.Keywords: benign paroxysmal positional vertigo, likelihood ratio, diagnosis, screening, prediction rules

    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 We lately reported the cases of patients complaining positional vertigo whose nystagmic pattern was that of a peripheral torsional vertical positional down beating nystagmus originating from a lithiasis of the non-ampullary arm of the posterior semicircular canal (PSC. We considered this particular pathological picture the apogeotropic variant of PSC benign paroxysmal positional vertigo (BPPV. Since the description of the pilot cases we observed more than 150 patients showing the same clinical sign and course of symptoms. In this paper we describe, in detail, both nystagmus of apogeotropic PSC BPPV (A-PSC BPPV and symptoms reported by patients trying to give a reasonable explanation for these clinical features. Moreover we developed two specific physical therapies directed to cure A-PSC BPPV. Preliminary results of these techniques are related.

    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.

    Full Text Available Background/Aim. Benign paroxysmal positional vertigo is one of the most frequent peripheral vestibular system disorders. The aim of this study was to examine the efficacy of the Epley maneuver in treating benign paroxysmal positional vertigo of the posterior semicircular canal (p- BPPV and to discover possible causes of failure. Methods. This prospective study included 75 patients. In all the cases medical history showed and the positioning Dix-Hallpike test confirmed the diagnosis of p-BPPV. We also performed clinical ENT examination, searching for spontaneous nystagmus, vestibulospinal tests, caloric test, and audiometry. All the patients were treated by the modified Epley canalith repositioning maneuver. The patients were followed up at the intervals of seven and, fourteen days, and one, tree, and six months and one year. The maneuver was repeated if vertigo and nystagmus on control positioning test persisted. The transition from positive into negative Dix Hallpike test after one or two Epley maneuver was considered as success in treatment. Results. After the initial Epley maneuver the recovery rate was 90.7%, and after the second 96%. In three (4% patients with secondary p-BPPV, symptoms did not cease even after the second repositioning maneuver. The etiology of p-BPPV had a significant effect on the maneuver’s success rate (p < 0.01, whereas duration of symptoms, age and gender had no effect (p > 0.05. After a successful treatment 11 (14.66% patients had recurrent attack of BPPV during the first year. Conclusion. The Epley maneuver is very successful repositioning procedure in treating p- BPPV. The patients with idiopathic form p-BPPV showed higher success rate with Epley maneuver than those with secondary p-BPPV.

    Full Text Available Introduction & Objective: Vertigo in the elderly is relatively common, but only a few studies are available. Vestibular rehabilitation (VR therapy is an important therapeutic option in treating patients with significant balance deficits. The purpose of this study was to analyze the effect of vestibular rehabilitation on vertigo symptoms in elderly patients with benign paroxysmal positional vertigo (BPPV. Materials & Methods: In a cross sectional analytic design, 46 patients older than 60 years (aged 61 to 72 years with BPPV who referred to the ENT center of Imam Khomeini Hospital, Ahwaz, were studied. After an otologic evaluation, videonystagmography and dizziness handicap inventory (DHI evaluations were performed for each case. Then, vestibular rehabilitation (VR therapy was carried out by means of Epley maneuver. Efficacy of a VRT was tested by comparing pre-treatment with post-treatment VNG and DHI assessments. The data were analyzed by SPSS 16 software. Results: The average age of the patients was 67.28 ± 4.5 years. VR caused normal Hallpike findings in 31 (67.4 % and noticeable reduction in nystagmus amplitudes in 9 patients. We found a significant correlation between nystagmus amplitudes and DHI scores (r=0.77. The mean DHI scores decreased from 53.26±16.12 points to 15.36±9.23 points (p<0.001 at the end of the treatment course. Conclusion: Our investigation revealed that VR plays an important role in reducing vertigo in at-risk elderly patients. Lack of appropriate treatment in this population may cause a serious balance problem (such as bone fracture and long-term handicap that may interfere with their daily activities.

    Full Text Available BACKGROUND: Dizziness/vertigo is one of the most common complaint and handicapping condition among patients aged 65 years and older (Geriatric patients. This study was conducted to assess the impact of dizziness/vertigo on the quality of life in the geriatric patients attending a geriatric outpatient clinic. SETTINGS AND DESIGN: A cross-sectional study was performed in a geriatric outpatient clinic of a rural teaching tertiary care hospital in central India. MATERIALS AND METHODS: In all consecutive geriatric patients with dizziness/vertigo attending geriatric outpatient clinic, DHI questionnaire was applied to assess the impact of dizziness/vertigo and dizziness associated handicap in the three areas of a patients' life: physical, functional and emotional domain. Later, each patient was evaluated and underwent Dix-Hallpike maneuver by the physician who was blind of the DHI scoring of the patient. STATISTICAL ANALYSIS USED: We compared means and proportions of variables across two categories of benign paroxysmal positional vertigo (BPPV and non-BPPV. For these comparisons we used Student's t-test to test for continuous variables, chi-square test for categorical variables and Fisher's exact test in the case of small cell sizes (expected value<5. RESULTS: The magnitude of dizziness/vertigo was 3%. Of the 88 dizziness/vertigo patients, 19 (22% and 69(78% cases, respectively, were attributed to BPPV and non-BPPV group. The association of DHI score ≥50 with the BPPV was found to be statistically significant with x(2 value = 58.2 at P<0.01. CONCLUSION: DHI Score is a useful tool for the prediction of benign paroxysmal positional vertigo. Correct diagnosis of BPPV is 16 times greater if the DHI Score is greater than or equal to 50. The physical, functional and emotional investigation of dizziness, through the DHI, has demonstrated to be a valuable and useful instrument in the clinical routine.

    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.

    Benign paroxysmal positional vertigo (BPPV) is a recurrent chronic disease and its handicap is usually underestimated. The aim of this study is to determine the impact of the treatment by Epley maneuver on short-term BPPV-related quality of life. Forty-two individuals with BPPV were included: 39 with posterior canal affected, 2 with the lateral canal and one with the anterior canal. Diagnosis was established if a consistent clinical history was found and Dix-Hallpike test (DHT) in cases with canal posterior involvement. Subjects with positive DHT were treated by a single Epley maneuver and were recommended to avoid supine for the next 48 hours. The BPPV relapses were investigated at 7th and 30th day post-treatment. BPPV-associated quality of life was evaluated by the Dizzness Handicap Inventory Short-form (DHI-S) at days 1st and 30th post-treatment. Total and partial scores for emotional, physical and functional subscales were compared by Wilcoxon test for paired samples. Dix-Hallpike test was found positive in el 59% individuals (23/39), and 41% cases did not required any treatment. Among 23 patients treated with Epley maneuver, DHT was found negative in 90% at 30th day follow-up. Mean and standard deviation of the total scores obtained in the DHI-S at the first day were 19.22 +/- 9.66 in the DHT positive-patients and 19.79 +/- 10.14 in the whole group (DHT positive or negative). These scores significantly decreased to 10.84 +/- 10.99 at 30 days post-treatment (p = 0.002 and p = 0.001, respectively). In conclusion, the DHI-S is a specific health questionnaire able to assess BPPV-related health and the effectiveness of treatment.

    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

    Full Text Available Bening paroxysmal positional vertigo (B.P.P.V is one of the most common vestibular disorders.During the last years, it has been attributed to cupulolithiasis or canalithiasis of the posterior semicircular canal.This randomized study was done to determine the effectiveness of two different physical therapy approaches and to determine if a single treatment approaches is enough.In this prospective study 80 patients received either a single treatment based on the hypothesis that the vertigo and nystagmus of (B.P.P.V are due to debris adhering to the cupula of posterior semicircular canal (cupulolithiasis, Semont maneuver, or a single treatment based on the hypothesis that the debris is free floating in the long arm of the posterior semicircular canal (canalithiasis, Epley maneuver.Treatment outcome was classified as asymptomatic, improved and no change. Analysis of the results of this study revealed that at the end of the first session , out of 80 patients, 60(75% were asymptomatic ; 14(18% improved ;6(7% showed no change. Follow­up showed that 8 patients developed recurrence. After a second session to 22 patients (8 recurrences, 10 improved, 4 had no change ,17 became asymptomatic.This means that at the end of the seconed session ,69 (86% of 80 patients became asymptomatic ; 9(11% of 80 patients improved ; 2(3% of 80 patients showed no change. In conclusion , this study shows that 1 The success rate of Semont's maneuver was up to 80%, so it is much better than Epley maneuver 70% after the first session. 2Recurrent cases are best treated with second session.

    Full Text Available The aim of this study is to verify the hypothesis that free-floating particles could sometimes localize into the distal portion of the non ampullary arm of the posterior semicircular canal (PSC so that assuming the Dix-Hallpike’s positions, the clot could move towards the ampulla eliciting a inhibitory torsional-down beating paroxysmal positional nystagmus (PPNy, instead of typical excitatory torsional-up beating PPNy. Among 45 patients with vestibular signs suggesting anterior semicircular canal paroxysmal positional vertigo (PPV, collected from February 2003 to August 2006, we detected a group of 6 subjects whose clinical findings showed a singular behaviour during follow-up. At the first check-up, all patients were submitted to different types of physical manoeuvres for ASC canalolithiasis. Patients were controlled during the same session and after one week. When we found that nystagmus was qualitatively changed we adopted the appropriate physical therapies for that sign. At a next check-up, after having performed some physical therapies, all patients had a typical PSC PPNy of the opposite side, with respect to that of the ASC initially diagnosed. Basing on these observations we conclude that PSC PPV, similarly to lateral semicircular canal PPV, could manifests in a apogeotropic variant.

The most common cause of dizziness in the elderly, benign paroxysmal positional vertigo (BPPV, is frequently undiagnosed, and bedside treatment of these patients can be difficult due to neck and back stiffness, which makes repeated and accurate repositioning maneuvers difficult. Case presentation: After a fall, a 96-year-old woman was referred by a resident neurologist for intractable BPPV. The patient was placed on a motorized turntable and repositioned to remove the calcite particles from the affected posterior semicircular canal. Video monitoring of the eyes allowed confirmation of the diagnosis, as well as an immediate evaluation of the effectiveness of the maneuver. Conclusion: Every patient with dizziness or imbalance, even in the absence of typical complaints of BPPV, should be tested with provocation maneuvers, because the clinical picture of BPPV is not always typical. Even if elderly patients with dizziness are very frail, the completion of provocation maneuvers is imperative, since the therapeutic maneuvers are extremely effective. A motorized turntable is very helpful to perform the repositioning accurately and safely. Keywords: vestibulo ocular reflex, nystagmus, vertigo

    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

    The vestibulo-ocular reflex (VOR) was studied via sinusoidal off-vertical axis rotation (OVAR) to evaluate the otolith function in patients with benign paroxysmal positional vertigo (BPPV). Subjects were sinusoidally rotated with eyes open in complete darkness at frequencies of 0.4 and 0.8 Hz with a maximum angular velocity of 60 degrees s(-1) in earth-vertical axis rotation (EVAR) and OVAR. Twenty-three controls and 24 BPPV patients were investigated. Results showed that VOR gain during OVAR at 0.8 Hz in a 30 degrees nose-up position in BPPV patients was significantly less than the gain during EVAR, whereas the gain was not significantly different between EVAR and OVAR in the controls in each condition. In addition, to examine each type of BPPV, we also investigated whether there were any differences between the patients who suffered from dizziness and those who did not. VOR gain in OVAR of BPPV patients who were suffering from dizziness was significantly less than that of BPPV patients without dizziness. Not only cupulolithiasis or canalolithiasis, but also otolith dysfunction was considered to be the possible origin of BPPV. Because sinusoidal OVAR produced minimal nausea compared to constant velocity OVAR, the stimulation of 0.8 Hz nose-up in sinusoidal OVAR may be used to evaluate otolith function without discomfort for patients.

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.

    Benign paroxysmal positioning vertigo (BPPV) is the most frequent vertiginous syndrome. It is caused either by free-floating otoliths in the semicircular canals (canalolithiasis) or by otoconial debris adhering to a canal cupula (cupulolithiasis). The posterior canal is the most frequently involved (80%), while the lateral canal is involved less frequently (15%), and the rarest conditions are anterior canalolithiasis and apogeotropic posterior canalolithiasis (5%). The main diagnostic sign of lateral canal BPPV is paroxysmal horizontal bidirectional positioning nystagmus evoked through Pagnini-McClure's test (head roll in the yaw plane in supine position). In the geotropic variant, which is more frequent, the fast phase of the nystagmus is directed towards the lowermost ear, when the patient lies on the affected side or on the healthy side; in the apogeotropic variant, which is less frequent, the fast phase is directed always toward the uppermost ear, regardless of which side the patient lies on. Paroxysmal nystagmus is more intense on the affected side in the geotropic form, and more intense on the healthy side in the apogeotropic form. The authors describe five cases of another primitive and rare form of lateral BPPV, defined as "direction-fixed paroxysmal nystagmus lateral canal BPPV", which has previously been described by other authors as a transitory step observed during the transformation from an apogeotropic into a geotropic form. It is characterized by typical BPPV symptoms and diagnosed by the presence of a paroxysmal horizontal unidirectional positioning nystagmus, evoked through Pagnini-McClure's test, which is apogeotropic on the affected side and geotropic on the healthy side. In the reported cases, direction-fixed horizontal paroxysmal nystagmus was always transformed into a typical geotropic form. The clinical features and pathophysiology of direction-fixed nystagmus lateral canal BPPV are discussed.

    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

    Introduction Benign Paroxysmal Positional Vertigo (BPPV) is one of the most common and treatable causes of peripheral vestibular vertigo in adults. Its incidence increases with age, eventually leading to disability and a decreased quality of life. Objective The research aims to assess short-term effects of Otolith Repositioning Maneuver (ORM) on dizziness symptoms, quality of life, and postural balance in elderly people with Benign Paroxysmal Positional Vertigo. Methods A quasi-experimental study, which evaluated 14 elderly people that underwent the Otolith Repositioning Maneuver and reevaluation after one week. The authors performed statistical analysis by descriptive analysis of central tendency and dispersion; for pre- and post-treatment conditions, the authors used the Wilcoxon test. Results All aspects of the Dizziness Handicap Inventory (physical, functional, emotional, and total scores) as well as the Visual Analogue Scale (VAS) decreased after therapy (p balance, there were significant differences in some parameters of the modified Clinical Test of Sensory Interaction and Balance, Limits of Stability and gait assessment measured by the Dizziness Gait Index (p balance improved. Therefore, a longer follow-up period and a multidisciplinary team are required to establish comprehensive care for elderly patients with dizziness complaints. PMID:26722348

    Full Text Available Introduction: Vertigo is a symptom that impacts the patients' quality of life and may force them to cease performing activities of daily living. Here, we discuss benign paroxysmal positional vertigo (BPPV and Meniere's disease (MD, which show exacerbated symptoms when they appear in association. Vestibular rehabilitation (VR is an effective treatment in reducing vertigo, especially in conjunction with other therapies. Aim: To evaluate the quality of life of patients with BPPV and MD before and after VR. Method: We conducted a descriptive observational qualitative and quantitative case study with 12 patients aged 35 to 86 years. All patients diagnosed with BPPV and MD received treatment in the ENT clinic. The Brazilian DHI questionnaire, which assesses the quality of life with a focus on physical, emotional, and functional aspects, was used for data collection, and was completed by patients before the first session and after the fifth session of VR. Data were tested using the Shapiro-Wilk normality test, followed by Wilcoxon, Friedman, and Spearman correlation tests (p < 0.05. Results: There were significant improvements in scores for all aspects, with median changes ranging from 12 to 0 in the physical, 6 to 1 in the emotional, and 11 to 1 in the functional aspect. There were no correlations between the scores and sample characteristics. Conclusion: VR was an effective method for the treatment of patients with BPPV and MD; it improves quality of life and shows the maximal influence on physical aspect scores, regardless of age or gender.

    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.

    This study was performed to determine whether a novel treatment was effective against cupulolithiasis associated with benign paroxysmal positional vertigo (BPPV) of the lateral semicircular canal, which is characterized by apogeotropic direction-changing nystagmus. We herein describe our head-tilt hopping (HtH) exercise, which is designed to release otoconial debris strongly adhered to the cupula. The subjects were trained to hop while tilting their heads laterally. They completed 3 to 5 exercise sessions per day over a 4-week period. Each session ended with a 20-hop trial. The HtH exercises were performed by 27 patients with intractable lateral canal BPPV who exhibited positional vertigo and persistent nystagmus beating toward the uppermost ear for more than 4 weeks, despite performing therapeutic head shaking in the horizontal plane maneuver. All the patients were subjected to the supine roll test before and immediately after the first trial as well as after 1 and 4 weeks of the program to evaluate the effect of the treatment on their apogeotropic nystagmus. Nystagmus of 9 (33.3 %) patients disappeared immediately after the first training session. After 1 and 4 weeks of the training, the number of patients that had experienced either of these improvements had increased to 15 (55.6 %) and 19 (70.4 %) subjects, respectively. These results suggest that HtH exercises aimed at releasing otoconial debris from the cupula are feasible as a new therapy for cupulolithiasis associated with intractable lateral canal BPPV. However, further studies for comparison with control are required to confirm these preliminary results.

    目的:探讨突发性聋伴良性阵发性位置性眩晕(benign paroxysmal positional vertigo,BPPV)患者的预后。方法回顾性分析105例突发性聋患者的临床资料,根据有无伴眩晕以及体位试验的结果分为三组:突发性聋伴BPPV组(13例)、突发性聋伴非BPPV眩晕组(27例)、突发性聋不伴眩晕组(65例),比较三组患者治疗前后的听力情况。结果突发性聋伴BPPV组与突发性聋伴非BPPV眩晕组听力损失较突发性聋不伴眩晕组重,且预后相对较差。结论BPPV是突发性聋的不良预后因素,耳石手法复位对BPPV治疗有效。%Objective To report treatment outcomes of idiopathic sudden sensorineural hearing loss (ISSNHL) with be-nign paroxysmal positional vertigo (BPPV). Methods Clinical data from 105 patients with ISSNHL were reviewed retro-spectively. Patients were divided into 3 groups based on vertigo symptoms and results of positional test, namely, ISSNHL with BPPV (n=13), ISSNHL with non BPPV vertigo (n=27) and ISSNHL without vertigo (n=65),for analysis of rela-tionship between hearing improvement and BPPV. Results Patients with ISSNHL and BPPV or non BPPV vertigo displayed worse hearing loss and had significantly less improvement as compared to those without vertigo. Conclusions BPPV is a poor prognostic factor in ISSNHL, but successful otolith repositioning can be achieved by proper canalith repositioning tech-niques.

  8. Efficacy of cervical and ocular vestibular-evoked myogenic potentials in evaluation of benign paroxysmal positional vertigo of posterior semicircular canal.

    Singh, Niraj Kumar; Apeksha, Kumari

    2016-09-01

    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.

    more than 3 sessions of posi-tional maneuvers during the first two weeks were more prevalent in patients older than 60 years of age. Cupulolithiasis, multiple-canal involvement, head trauma and inner ear ischemia may be factors that can lead to poor curative effect. It is difficult for these patients to recover through single repositioning maneuver. Most of them need several repositioning ma-neuver approaches, combined with postural training and drugs. Repositioning maneuver may not be effective in a small number of these patients.

    Full Text Available A Vertigem Posicional Paroxística Benigna (VPPB é uma das mais freqüentes patologias do sistema vestibular e é caracterizada por episódios de vertigens recorrentes desencadeados por movimentos da cabeça ou mudanças posturais. Há várias opções para o seu tratamento, porém as efetividades terapêuticas das mesmas permanecem controversas. OBJETIVO: Avaliar a efetividade terapêutica das manobras específicas disponíveis para o tratamento da VPPB. METODOLOGIA: Realizou-se uma busca eletrônica nas principais bases de dados, selecionando-se estudos clínicos randomizados envolvendo adultos com diagnóstico de VPPB confirmado com o teste de Dix-Hallpike e tratamento com manobras específicas (Epley ou Semont, por exemplo. Considerou-se como desfecho clínico a negativação do teste de Dix-Hallpike e a melhora das queixas subjetivas. Agruparam-se em metanálise os estudos com Escala de Jadad igual ou superior a três. RESULTADOS: Cinco estudos clínicos preencheram os critérios de inclusão, ou seja, ensaios randomizados de fase I comparando a manobra de Epley com placebos e controles. A metanálise mostra evidência dos efeitos benéficos da manobra de Epley para o tratamento do canal semicircular posterior (magnitude do efeito de 0,11 [IC 95% 0.05, 0.26] de melhora objetiva (Dix-Halpike após uma semana, 0.24 [IC 95% 0.13, 0.45] após um mês e 0.16 [IC 95% 0.08, 0.33] de melhora referida pelos pacientes após a primeira semana. CONCLUSÃO: Evidencia-se boa eficácia clínica da manobra de Epley para o tratamento da VPPB do canal semicircular posterior. Contrariamente, trabalhos com a manobra de Semont e as propostas de manejo dos demais canais semicirculares não obtiveram qualidade metodológica satisfatória, não sendo possível demonstrar a efetividade dos mesmos.Benign Paroxysmal Positional Vertigo (BPPV is one of the most frequent diseases of the vestibular system and it is characterized by episodes of recurrent vertigo

    We report a 44-year-old man who had apogeotropic nystagmus with the rotation of his head to either side from the supine position. His nystagmus lasted more than 2 minutes and was difficult to treat with. There were no neurological abnormalities except for the nystagmus and no findings suggesting intracranial disease on MRI. The head-position in which more intense nystagmus was evoked changed again and again in a short term. We diagnosed his illness as cupulolithiasis of horizontal canal, however, the affected ear could not be explained by any of the previously supposed mechanisms. In our case, we speculate the following mechanism. Otoliths were located on the right utricular side of the cupula. All of them were attached on the cupula at the beginning(attached phase) and then, some of them were detached from it(detached phase). The extent of the cupular deviation differed in each phase when the otoliths were beneath the cupula with his head turned to the left lateral position. According to Ewald's second law, more intense nystagmus is evoked when the cupula deviates toward the utricle than away from it. The patient's head-position in which more intense nystagmus was evoked changed according to the balance between the effect of Ewald's second law and the amount of otoliths detached from cupula. Our case showed that, in HC-BPPV with direction-changing apogeotropic nystagmus, we could not be certain about which ear was diseased. Therefore, it may be difficult to apply exercise therapy by determining the affected ear based on the head-position in which more intense nystagmus is evoked.

    Because inner ear organs are interconnected through the endolymph and surrounding endolymphatic membrane, the patients with sudden sensorineural hearing loss (SSNHL) often complain of vertigo. In this study, we report a patient with SSNHL accompanied by persistent positional vertigo, and serial findings of head-roll tests are described. At acute stage, head-roll test showed persistent geotropic direction-changing positional nystagmus (DCPN), which led to a diagnosis of SSNHL and ipsilateral light cupula. Although vertigo symptom gradually improved, positional vertigo lasted for more than 3 weeks. At this chronic stage, persistent apogeotropic DCPN was observed in a head roll test, which led to a diagnosis of the heavy cupula. Although the mechanism for the conversion of nystagmus direction from geotropic to apogeotropic persistent DCPN is unclear, the change of specific gravity of the endolymph might be one of the plausible hypothetical explanations.

    The purpose of this study is to review etiologies and identify the time-course of vertigo presenting in an ear, nose, and throat clinic, and serve as a reference guide for other clinics. The study includes retrospective chart review in a tertiary care, university hospital. The patient data with reported ICD-10 codes as causes of vertigo between April 2005 and December 2007 were extracted from the database. At each visit, the main diagnosis as to etiology, characteristics of the vertigo, its time-course, and patient demographic data were recorded. Of 547 cases, 17 diagnoses were made in 73.9%. Diagnostic categories included peripheral vertigo 72.9%, central vertigo 0.8%, psychogenic cause 0.2%, and unknown 26.1%. Common causes of vertigo were benign paroxysmal positional vertigo (BPPV) 52.5%, Meniere's disease 14.6%, and sudden idiopathic hearing loss 2.9%. Less common diagnoses were benign paroxysmal vertigo of childhood 0.7%, labyrinthitis 0.7%, and vestibular schwannoma 0.3%. Rare conditions were delayed endolymphatic hydrops, Ramsey Hunt syndrome, otosyphilis, vestibular neuritis, temporal bone fracture, post-concussion syndrome, cerebellar infarction, epilepsy, cervical vertigo, Streptococcus suis meningitis, and psychogenic vertigo. Ninety-nine cases who reported remission of vertigo during the study period had median onset of the remission at 4 weeks. In the ear, nose, and throat clinic at Chiang Mai University, a tertiary university hospital, peripheral vestibular disorders were the main etiology of vertigo. The three most common causes were BPPV, Meniere's disease, and sudden idiopathic hearing loss. Half of the cases who returned for follow up had remitted symptoms within 4 weeks.

    2015-06-01

    Full Text Available The prevalence of vertigo and dizziness in people aged more than 60 years reaches 30%, and due to aging of world population, the number of patients is rapidly increasing. The presence of dizziness in the elderly is a strong predictor of falls, which is the leading cause of accidental death in people older than 65 years. Balance disorders in the elderly constitute a major public health problem, and require an adequate diagnosis and management by trained physicians. In the elderly, common causes of vertigo may manifest differently, as patients tend to report less rotatory vertigo and more nonspecific dizziness and instability than younger patients, making diagnosis more complex. In this mini review, age-related degenerative processes that affect balance are presented. Diagnostic and therapeutic approaches oriented to the specific impaired system, including visual, proprioceptive, and vestibular pathways are proposed. In addition, presbystasis -the loss of vestibular and balance functions associated with aging-, benign paroxysmal positional vertigo, and stroke (in acute syndromes should always be considered.

    Full Text Available Objective: Despite the high prevalence of vertigo globally and an acknowledged, but underreported, effect on an individual’s wellbeing, few studies have evaluated the burden on healthcare systems and society. This study was aimed to quantitatively determine the impact of vertigo on healthcare resource use and work productivity. Methods: The economic burden of vertigo was assessed through a multi-country, non-interventional, observational registry of vertigo patients: the Registry to Evaluate the Burden of Disease in Vertigo (REVERT. Patients included were those with a new diagnosis of Meniere’s disease (MD, benign paroxysmal positional vertigo (BPPV, other vertigo of peripheral vestibular origin or peripheral vestibular vertigo of unknown origin. Results: A total of 4,294 patients at 618 centers in 13 countries were included during the registry. Of the 4,105 patients analyzed, only half were in employment. Among this working patient population, 69.8% had reduced their workload, 63.3% had lost working days and 4.6% had changed and 5.7% had quit their jobs, due to vertigo symptoms. Use of healthcare services among patients was high. In the 3 months preceding Visit 1, patients used emergency services 0.4 ± 0.9 times, primary care consultations 1.6 ± 1.8 times and specialist consultations 1.4 ± 2.0 times (all mean ± SD. A mean of 2.0 ± 5.4 days/patient was also spent in hospital due to vertigo.Conclusions: In addition to the negative impact on the patient from a humanistic perspective, vertigo has considerable impact on work productivity and healthcare resource use.

    Full Text Available Betahistine hydrochloride is the drug of choice for the treatment of vestibular vertigo in the presence of benign paroxysmal positional vertigo, Meniere's disease, and vestibular neuronitis. Effective combination therapy regimens that contain, along with drugs from other pharmacological groups, betahistine hydrochloride that improves blood circulation in the vestibular structures, accelerates vestibular compensation, and prevents recurrent dizzy spells, have been elaborated to treat central vestibular vertigo in migraine-associated dizziness and in acute cerebrovascular accident. Of great importance is a combination of drug therapy and the current rehabilitation methods for vestibular diseases, which contribute to prompter and complete recovery of vestibular function. Biofeedback instrumental rehabilitation techniques using a stabilographic platformare highly effective. Successful treatment depends on the correctness of the established diagnosis. The diagnosis of peripheral and central vestibular vertigo frequently poses challenges. The essential reason for this is physicians’ unawareness about outpatient methods for the diagnosis of major vestibular diseases when the patient is at a doctor. It is important to follow a vestibular system study protocol since the use and correct assessment of diagnostic tests in most cases make it possible to estimate the degree of vestibular analyzer injury and to make an accurate diagnosis. The paper describes the diseases that are the most common causes of vestibular vertigo. The most effective methods for their treatment and current rehabilitation methods are discussed.

    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.

    Full Text Available Vertigo is a common symptom in everyday clinical practice. The treatment depends on the specific etiology. Vertigo may be secondary to inner ear pathology, or any existing brainstem or cerebellar lesion but may also be psychogenic. Central vertigo is a consequence of a central nervous system lesion. It is often associated with a focal neurological deficit. Peripheral vertigo is secondary to dysfunction of the peripheral vestibular system and is usually characterized by an acute vertigo with loss of balance, sensation of spinning in the space or around self, and is exaggerated with changes of the head and body position; no other neurological deficit is present. Some medications may also cause vertigo. Depending on the cause of the vertigo, drugs with different mechanisms of action, physical therapy, psychotherapy, as well as surgery may be used to combat this disabling malady. Symptomatic treatment has a particularly important role, regardless of the etiology of vertigo. We reviewed the current medications recommended for patients with vertigo, their mechanisms of action and their most frequent side effects.

  6. Vertigo and dizziness in children.

    Vertigo and dizziness of at least moderate severity occur in >5% of school-aged children and cause considerable restrictions in participation in school and leisure activity. More than 50% of dizzy children also have headache. Vestibular migraine and benign paroxysmal vertigo as a migraine precursor are the most common diagnoses in dizziness clinics for children and adolescents. They account for 30-60% of diagnoses. Other common causes are somatoform, orthostatic, or posttraumatic dizziness. All other disorders that are known to cause vertigo and dizziness in adults also occur in children, but incidence rates are usually lower. The vestibular and balance systems are largely developed after 1 year of age. Therefore, clinical and laboratory testing is reliable. Brain magnetic resonance imaging to exclude severe conditions, such as a brainstem tumor, is necessary only if clinical - in particular, ocular motor - testing is abnormal. Most conditions causing vertigo and dizziness in childhood and adolescence are treatable. Nonpharmacologic prophylaxis should always be recommended in vestibular migraine. Behavioral support is useful in somatization. Evidence for the effectiveness of drug therapy is largely based on experience in adult populations. High-quality controlled studies in childhood cohorts are sparse. It is important to make a correct diagnosis early on, as counseling and appropriate treatment may avoid chronic illness.

    Full Text Available Background and Aim: Cervicogenic dizziness is induced by a specific neck position and the earth’s gravity has no effect on provoking of it. The precise incidence of cervicogenic dizziness is not certain but, 20-58% of patients following sudden head injuries experience its symptoms . In this article, the etiology, diagnosis and treatment of cervicogenic vertigo is discussed. Methods: At first, articles of cervicogenic dizziness from electronic databases of Google scholar , PubMed, Scopus, Ovid and CINAHL were searched from 1987 up to 2012. Then, the articles in them vertigo, disequilibrium or nystagmus were consistent with neck disorders were searched. Conclusion: Articles with title of cervicogenic vertigo (cervical vertigo were limited. Clinical researches about cervicogenic vertigo up to now implicate on several points; all signify that we cannot diagnose it certainly and there is not any specific single test for that. Recently, smooth pursuit neck torsion test (SPNTT has introduced for diagnosis of cervicogenic vertigo that is not valid yet. There is no protocol for diagnosis of cervicogenic vertigo and diagnosis is often based on limited clinical experiences of clinicians. Physiotherapy, medication and manual therapies are options for treatment but there is no distinct and effective treatment for it and in just one article, a combination of treatments for cervicogenic vertigo as a protocol has recommended.

  8. Particle sedimentation in curved tubes: A 3D simulation and optimization for treatment of vestibular vertigo

    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.

    Acute vertigo may originate from peripheral or central vestibular disorders. As central vestibular symptoms may indicate severe brainstem or cerebellar ischemia, rapid clinical differentiation is required. To this end, evaluation of spontaneous or gaze-evoked nystagm, head-impulse test as well identification of skew deviation are most helpful. PMID:27464281

    The current study investigated the association between temporomandibular disorders, malocclusion patterns, benign joint hypermobility syndrome and the initial condylar position. One hundred sixty-two subjects were analyzed using the Rocabado Temporomandibular Pain Analysis; Helkimo Index parameters; the Carter-Wilkinson modified test; and a mounting cast with condylar position indicator registration (MPI). The study revealed a significant association between: 1. Delta H, skeletal pattern (p = 0.034); 2. Delta Y, transversal malocclusion (p = 0.04); 3. right and left, Delta Z, right and left posteroinferior synovial pain (p < 0.05); 4. hypermobility scale, gender (p < 0.001), malocclusion pattern (p = 0.021); 5. TMJ function impairment, gender (p = 0.043); 6. sagittal malocclusion pattern, right temporomandibular pain analysis joint (TPAJ) (p = 0.0034); 7. TMJ function impairment, left and right TPAJ (p = 0.007); and 8. mandibular motion, left and right TPAJ (p = 0.035, p = 0.015). The conclusion was that anterior crossbite and condylar displacements in the vertical plane are risk factors in developing TMJ symptoms.

    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

    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. Vertigo questionnaires are powerful tools for clinicians in detecting vertigo and a thorough understanding of the history and symptoms helps the clinician in selecting appropriate diagnostic techniques.%目的 探讨学龄前儿童眩晕的常见病因、临床表现特点及合理的诊断方法.方法 回顾性分析12例学龄前儿童眩晕的临床表现特点、诊疗经过、结果及家长对各项诊断方法的接受程度.结果 (1) 12例患儿的诊断结果为:分泌性中耳炎3/12,儿童良性发作性眩晕3/12,内耳畸形3/12,良性阵发性位置性眩晕2/12,梅尼埃病1/12.(2)患儿年龄越小,典型的眩晕主诉越少,多表现为摔倒、行走不稳、行动笨拙、恐惧和害怕,能主诉眩晕的患儿最小年龄5.5

    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

    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...

  2. Initial evaluation of vertigo

    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. .

    Introduccion. Uno de los dilemas mas importantes concernientes al vertigo en urgencias es su diagnostico diferencial. Existen signos de alarma de gran sensibilidad en la exploracion que pueden ponernos en la pista de encontrarnos ante un vertigo central. Objetivo. Determinar la eficacia de la aplicacion del protocolo HINTS en el diagnostico del accidente cerebrovascular que simula un vertigo periferico. Pacientes y metodos. Estudio observacional descriptivo sobre pacientes ingresados con diagnostico de sindrome vestibular agudo en urgencias. Todos los pacientes fueron objeto de un seguimiento diario hasta la mejoria de sus sintomas con informacion del nistagmo, la maniobra de impulso oculocefalico y el test de skew. Se comparan los resultados del estudio de resonancia magnetica con la alteracion en alguno de esos tres signos a lo largo del ingreso del enfermo. Resultados. Se reunio a 91 pacientes, con una edad media de 55,8 años. Se objetivo un accidente cerebrovascular en ocho de ellos. De estos (edad media: 71 años), en siete existia una alteracion en alguno de los signos HINTS y en uno el estudio fue normal (sensibilidad: 0,88; especificidad: 0,96). Todos ellos tenian algun factor de riesgo vascular. Conclusiones. Una exploracion adecuada y dirigida ante un paciente que acude a urgencias con un sindrome vestibular agudo resulta de vital importancia para establecer el diagnostico diferencial entre la patologia periferica y la central, ya que algunos accidentes cerebrovasculares se pueden presentar bajo la apariencia de un vertigo agudo. Aplicar un protocolo como HINTS permite sospechar la patologia central con una gran sensibilidad y especificidad.

  7. 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)

    Headache and vertigo often emerge simultaneously. Fifty six (40%) out of 140 patients complaining of vertigo were studied. Emerging in the aura and/or in headache phases, vertigo was more frequently registered in patients suffered from migraine with aura (57%). Vertigo associated with migraine was diagnosed in 25% of the cases. The patients were randomized into 2 equal identical groups, one of which was treated by betaserc (16 mg, 3 times daily before meal) and the other one was given cinnarizine (25 mg, 3 times daily). Treatment duration was 12 weeks. Reduction of vertigo attacks frequency and headache by 50% and over, in comparison to the baseline period, was considered as beneficial. Fifty three (95%) patients completed the treatment course. Decrease of a risk for negative results and a frequency of positive effect of vertigo therapy were significantly higher in the group receiving betaserc. Reduction of monthly relapses by 50% and over was detected in 79% of the patients of betaserc group and in 52% of those of cinnarizine one. Migraine attacks monthly frequency was diminished by 43% and 64%, respectively. Therefore, betaserc is considered for using as vertigolytic medication and for migraine attacks prevention.

    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...

    To investigate the long-term outcome of interdisciplinary treatment in a tertiary care neuro-otology institution after 2 years as part of the Dizziness and Vertigo Registry study. Risk factors associated with unfavourable outcome were assessed. 3113 consecutive patients with disorders of vertigo and dizziness were recruited prospectively between March 2010 and February 2012. Patients were clinically assessed and treated according to their diagnosis. Standardized instruments were used at baseline and at 2-year follow-up [Dizziness Handicap Inventory (DHI), Quality of Life Questionnaire, General Depression Scale, Stait-Trait Anxiety Index], as well as a custom health-related questionnaire. The primary outcome variable of this observational study was the change in DHI after 2 years. Patients suffered from phobic postural vertigo (23%), benign peripheral paroxysmal vertigo (14.4%), unilateral vestibulopathy (10.5%), central vestibular disorders (8%), Menière's disease (9.8%), vestibular migraine (6.9%), bilateral vestibulopathy (5.5%), and vestibular paroxysmia (3.1%). Mean disease duration was 4.6 ± 6.3 years. 1272 patients were available for follow-up, 1159 completed the DHI score. 72.1% of patients improved in DHI score from baseline to 2 years follow-up. Mean reduction in DHI score was 14 points (p = 0.02). Long-term outcome following diagnosis and treatment in a specialized tertiary care centre is good and persistent after 2 years. Risk factors for an unfavourable outcome were advanced age, severe disability, constant vertigo or dizziness, and concomitant back pain, while depression and anxiety did not contribute to this risk considerably.

    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。

Duration of symptoms and impact on daily life activities were assessed.72.0% (95%-CI = [69.8-74.2]; N = 1196 of the students (mean age 14.5±1.1 reported to suffer from at least one episode of dizziness or vertigo in the last three months. Most adolescents ticked to have symptoms of orthostatic dizziness (52.0%, 95%-CI = [49.5-54.4], N = 863. The period prevalence for the other types of vertigo were spinning vertigo: 11.6%, 95%-CI = [10.1-13.3], N = 193; swaying vertigo: 12.2%, 95%-CI = [10.6-13.8], N = 202; and unspecified dizziness: 15.2%, 95%-CI = [13.5-17.1], N = 253. 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.

    La Mettrie's materialist and monistic philosophy is that of a military doctor, knowing what dysentery did to his own mind, watching his regiment destroyed at Fontenoy, running French field hospitals in Flanders. He learned brain science in the injuries of his fellows. He knew pain and that man's main positive drive was sex. He despised the prudish hypocrisies of feeble materialists like Diderot and Voltaire. His brutal military life and his hedonism made him the most coherent monist against Cartesian dualism. His study of vertigo is sound clinical medicine, which well accords with one trend in today's medical practice. PMID:19831303

    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.

    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.

    Vertigo has been described after the practice of mountain bike. This study aimed to investigate the prevalence of vertigo following competitions or training sessions of downhill mountain biking (DMB) or road cycling (RC). One hundred and two DMB riders, 79 road cyclists and 73 control participants filled in a survey intended to evaluate the prevalence of vertigo in daily living activities and following competitions or training sessions. Vertigo causal factors (crashes, head trauma, fatigue, characteristics of the path/road ridden) were recorded. DMB riders and road cyclists did not report more vertigo during daily living activities than controls. But DMB riders older than 30 had more risk to report vertigo than age-matched road cyclists (OR: 5.06, 95% CI: 1.23-20.62). Road cyclists aged between 20 and 29 were 2.59-fold (95% CI: 1.06-6.27) more likely to report vertigo than controls. After competitions and training sessions, DMB riders were 2.33-fold (95% CI: 1.22-4.41) more likely to report vertigo than road cyclists. Vertigo causal factors were crash with head trauma in DMB riders and fatigue in road cyclists. Vertigo during daily living activities may be of concern for cyclists, particularly older DMB riders. The accumulation of impacts (crashes, vibrations) during the career of a DMB rider may generate micro-traumatisms of the central nervous system and/or peripheral vestibular structures, particularly the otolith organs. In RC, the pathophysiological mechanisms generating vertigo might be effort-related disturbance of homeostasis. To avoid injuries, DMB riders should be aware that vertigo may occur at the end of training sessions or competitions.

    Full Text Available 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.

    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.

    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 Introduction: Vertigo prevalence is estimated to be 1.8% among young adults and more than 30% in the elderly. 13-38% of the referrals of patients over 65 years old in America are due to vertigo. Vertigo does not increase the risk of mortality but it can affect the patient’s quality of life. Therefore, this study was designed to evaluate the epidemiologic characteristics of vertigo patients referred to the emergency department (ED. Methods: In this 6-month retrospective cross-sectional study, the profiles of all vertigo patients referred to the ED of Imam Hossein Hospital, Tehran, Iran, from October 2013 to March 2014 were evaluated. Demographic data and baseline characteristics of the patients were recorded and then patients were divided into central and peripheral vertigo. The correlation of history and clinical examination with vertigo type was evaluated and screening performance characteristics of history and clinical examination in differentiating central and peripheral vertigo were determined. Results: 379 patients with the mean age of 50.69 ± 11.94 years (minimum 18 and maximum 86 were enrolled (58.13% female. There was no sex difference in vertigo incidence (p = 0.756. A significant correlation existed between older age and increase in frequency of central cases (p < 0.001. No significant difference was detected between the treatment protocols regarding ED length of stay (p = 0.72. There was a significant overlap between the initial diagnosis and the final decision based on imaging and neurologist’s final opinion (p < 0.001. In the end, 361 (95.3% patients were discharged from ED, while 18 were disposed to the neurology ward. No case of mortality was reported. Conclusion: Sensitivity and specificity of history and clinical examination in differentiating central and peripheral vertigo were 99 (95% CI: 57-99 and 99 (95% CI: 97-99, respectively.

    2016-01-01

    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.

    Full Text Available 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.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.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.While most infants with VCC and Unknown CFTR mutations do not meet diagnostic criteria for CF, a small proportion do.

We present a patient with isolated intermittent vertigo attributable to the embryonic anastomosis and describe the different types of persistent trigeminal artery. A 76-year-old Caucasian man presented with isolated intermittent vertigo and symptoms suggestive of anterior and posterior circulation strokes. Impaired vasomotor reactivity was demonstrated on insonation of the anterior and posterior cerebral arteries in this patient with a persistent left trigeminal artery and 75% stenosis of the left internal carotid artery (ICA. The symptom of intermittent vertigo resolved with carotid endarterectomy. Decreased flow across the stenotic segment of the ICA which subserved the posterior circulation resulted in basilar insufficiency. Hypoperfusion to the flocculonodular lobe supplied by the anterior inferior cerebellar artery is a likely cause for the intermittent vertigo.

    @@ The common symptoms of cervical spondylopathy include dizziness and vertigo, headache, neck rigidity and numbness, or pain in the shoulders, arms, and fingers. Modem medicine has divided cervical spondylopathy into 6 types, namely, the cervical,radicular, spinal, vertebroarterial, sympathetic, and the mixed types. In TCM, according to the main symptoms of dizziness and vertigo, cervical spondylopathy is traditionally called ‘cervical vertigo'. Having been engaged in TCM for more than 40 years, Prof. Luo Zhiqiang (罗致强) has acquired a profound and unique knowledge about this disorder and obtained quite good therapeutic results. The following is a brief introduction of his experience in the TCM treatment of cervical vertigo.

    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

    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.

    Full Text Available Background and Objectives: Intratympanic gentamicin therapy is an effective modality for control of vertigo in Meniere's disease (MD and when given in low concentration (<30 mg/mL, once weekly minimizes its side effects like chronic vestibular insufficiency or hearing loss. We studied the efficacy of low dose interval intratympanic gentamicin therapy in control of intractable vertigo in MD and the postprocedure hearing loss. As gentamicin is vestibular end-organ selective and not specific for treatment of MD alone we studied its efficacy in non-Meniere's peripheral vertigo (NMPV in patients with nonserviceable hearing in affected ear. Subjects and Methods: Our study included 13 patients with “Definite” MD and seven patients with NMPV. In MD group, one treatment series consisted of a maximum of 3 weekly intratympanic gentamicin injections of 0.3 mL (12 mg of gentamicin. In NMPV group, the schedule was similar but dosage per injection was 0.5 mL (20 mg. Another similar series of injections were repeated for recurrences. Results: Significant reduction was noted in number of vertigo spells in both groups after treatment (P < 0.001. All the patients experienced either complete or substantial control (Class A or B of their vertigo. The functional level scale had significantly improved posttreatment in both groups (P < 0.01. No significant worsening in hearing was noted in any of the patients in MD group. Interpretation and Conclusion: Low dose interval intratympanic gentamicin is a simple cost-effective office procedure for managing vertigo in patients with MD and in patients with NMPV and nonserviceable hearing.

  18. Betahistine treatment in managing vertigo and improving vestibular compensation: clarification.

    Science.gov (United States)

    Lacour, Michel

    2013-01-01

    Betahistine dihydrochloride (betahistine) is currently used in the management of vertigo and vestibular pathologies with different aetiologies. The main goal of this review is to clarify the mechanisms of action of this drug, responsible for the symptomatic relief of vertigo and the improvement of vestibular compensation. The review starts with a brief summary recalling the role of histamine as a neuromodulator/neurotransmitter in the control of the vestibular functions, and the role of the histaminergic system in vestibular compensation. Then are presented data recorded in animal models demonstrating that betahistine efficacy can be explained by mechanisms targeting the histamine receptors (HRs) at three different levels: the vascular tree, with an increase of cochlear and vestibular blood flow involving the H1R; the central nervous system, with an increase of histamine turnover implicating the H3R, and the peripheral labyrinth, with a decrease of vestibular input implying the H3R/H4R. Clinical data from vestibular loss patients show the impact of betahistine treatment for the long-term control of vertigo, improvement of balance and quality of life that can be explained by these mechanisms of action. However, two conditions, at least, are required for reaching the betahistine therapeutic effect: the dose and the duration of treatment. Experimental and clinical data supporting these requirements are exposed in the last part of this review.

    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

  7. 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.

    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.)

    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.

  10. Is Vestibular Neuritis an Immune Related Vestibular Neuropathy Inducing Vertigo?

    Full Text Available Objectives. To review the current knowledge of the aetiology of vestibular neuritis including viral infections, vascular occlusion, and immunomediated mechanisms and to discuss the pathogenesis with relevance to pharmacotherapy. Systematic Review Methodology. Relevant publications on the aetiology and treatment of vestibular neuritis from 1909 to 2013 were analysed. Results and Conclusions. Vestibular neuritis is the second most common cause of peripheral vestibular vertigo and is due to a sudden unilateral loss of vestibular function. Vestibular neuronitis is a disorder thought to represent the vestibular-nerve equivalent of sudden sensorineural hearing loss. Histopathological studies of patients who died from unrelated clinical problems have demonstrated degeneration of the superior vestibular nerve. The characteristic signs and symptoms include sudden and prolonged vertigo, the absence of auditory symptoms, and the absence of other neurological symptoms. The aetiology and pathogenesis of the condition remain unknown. Proposed theories of causation include viral infections, vascular occlusion, and immunomediated mechanisms. The management of vestibular neuritis involves symptomatic treatment with antivertiginous drugs, causal treatment with corticosteroids, and physical therapy. Antiviral agents did not improve the outcomes.

    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.

    Benign cephalic histiocytosis is a self-healing non-X, nonlipid cutaneous histiocytosis of children, characterized by a papular eruption on the head. Mucous membranes and viscera are always spared. In the 13 cases reported herein, the children were otherwise in good general health. The disease appeared during the first three years of life, and spontaneous regression was complete by the age of nine years in the four cases healed to date. The histiocytic infiltrate was localized in the upper and middle dermis and contained no lipids at any stage of evolution. All the histiocytes contained coated vesicles, and 5% to 30% also contained comma-shaped bodies in their cytoplasm.

    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

    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.)

    Skandalakis, John E; Mirilas, Petros

    2003-06-01

    Nihilism is the belief that all possible knowledge on a given topic has been amassed and codified. Ranging from benign denial to deliberate attempts at excommunication, nihilism is often encountered in the history of medicine. Eustachius, Columbus, and Sylvius strongly criticized Vesalius and defended the authority of Galen. Riolan fervently rejected Harvey's monumental work on the circulation of blood. Gross stated that no honest and sensible surgeon would ever sanction thyroidectomy. Sandstrom's discovery of the parathyroids was met with silence. Transplantation of parathyroids by Mandl was not appreciated when announced. Aristotle's dictum that the heart cannot withstand serious injury led to Paget's statement that cardiac surgery had reached the limits set by nature, which no new techniques could overcome. The first Billroth I operation was welcomed as, "Hopefully, also the last." Pancreatic surgery was opposed because the organ was of no clinical interest and was impossible for surgeons to reach. Pancreatic transplantation was rejected for many years, despite good results. When Blundell used blood transfusion for postpartum hemorrhage, critics averred that his next exploit would be radical removal of the spleen. Bassini stated that it could be risky to publish more about radical treatment of inguinal hernias. Carcinomas of the lower sigmoid and upper rectum were deemed untreatable because of their inaccessibility. Colostomy during pediatric surgery was rejected many times. Although it is difficult for the human mind to move from a familiar point of view, this propensity should not infect science, thereby impeding advancement.

    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.

    The efficacy and safety of the fixed combination of cinnarizine 20 mg and dimenhydrinate 40 mg in the treatment of vertigo of various origins have been investigated in a prospective, noninterventional study involving private practices throughout Germany. A total of 1275 patients with an average age of 61.2 years participated in the study. The vertigo symptoms, measured by a validated mean vertigo score (primary efficacy endpoint) improved by 61 % in the course of the observational period (median: 6 weeks). Concomitant symptoms frequently associated with vertigo such as nausea, vomiting and tinnitus were also markedly reduced by 84, 85 and 51 %, respectively. Overall efficacy has been rated by the physicians as 'very much improved' or 'much improved' in 95 % of the patients. A total of 47 patients (3.7 %) reported 51 adverse drug reactions (all nonserious). The results indicate a good tolerability and efficacy of the fixed combination of cinnarizine and dimenhydrinate in the treatment of vertigo in daily medical practice, which is in line with previous findings of numerous interventional, randomised, double-blind, controlled clinical trials.

    Purpose: In this study the potential of diphenhydramine in reducing respectively preventing vertigo and nausea induced by the ultra-high static magnetic field at 7 T was evaluated. Materials and methods: In a prospective, double blinded, placebo controlled, cross-over randomized study the sensations of 34 volunteers before, during and after exposure to the static magnetic field with and without drug respectively placebo administration were quantified. Fast table motion was applied to increase the incidence of otherwise sparse reports of field related sensations. Results: The strength of vertigo can be reduced by the application of diphenhydramine. Conclusion: Diphenhydramine, even at a low dose, reduces the strength of vertigo at ultra-high static magnetic fields, may be used preventively, and could pave the way to even higher field strength.

  10. Radical pancreaticoduodenectomy for benign disease.

    2008-01-01

    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

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 in

    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

  19. Surgery for Benign Salivary Neoplasms.

    2016-01-01

    Salivary neoplasms are relatively infrequent entities that account for only 4% of tumors of the head and neck. Although slow-growing lesions of the preauricular area and submandibular space are often confused with sebaceous cysts, lymph nodes, or lipomas by the non-otolaryngologist, otolaryngologists-head and neck surgeons recognize that all preauricular and submandibular masses should be considered a salivary neoplasm until proven otherwise. Surgery remains the treatment of choice for benign salivary gland neoplasms; however, techniques continue to evolve in order to preserve salivary function and reduce surgical morbidity. The goals of management of benign salivary neoplasms include accurate diagnosis of the lesion, complete surgical extirpation, and functional preservation of adjacent cranial nerves. Accurate diagnosis is aided by appropriate preoperative physical examination, imaging, and fine needle aspiration biopsy. Benign neoplasms typically present as slow-growing, painless, mobile masses without adverse features, such as tissue fixation, ulceration, a cranial nerve deficit, or regional lymphadenopathy. Preoperative imaging with ultrasonography, computed tomography, or magnetic resonance imaging reveals well-circumscribed lesions without an infiltrative growth pattern or associated adenopathy. Fine needle aspiration biopsy may favor a benign neoplasm, supporting the clinical presentation. Surgery for a benign or malignant salivary neoplasm is in essence a false dichotomy since the surgeon can never be completely confident of the diagnosis until the specimen is removed. The surgeon must recognize the significant overlap between benign and malignant salivary masses in terms of clinical presentation, imaging, and cytology, which requires the surgeon to remain vigilant and flexible at the time of surgery should tissue characteristics or frozen section analysis suggest a malignant process.

    Thirty-seven patients suffering from vertigo associated with vertebrobasilar insufficiency participated in our prospective, single-center, double-blind, comparative study. Patients were randomly allocated to treatment with placebo; betahistine (12 mg betahistine dimesylate, one tablet three times daily); or the fixed combination of 20 mg cinnarizine and 40 mg dimenhydrinate (one tablet three times daily) for 4 weeks. The primary efficacy end point was the decrease of the mean vertigo score (S(M)), which was based on the patients' assessments of 12 individual vertigo symptoms after 4 weeks of treatment. Patients treated with the fixed combination showed significantly greater reductions of S(M) as compared to patients receiving placebo (p < .001) or the reference therapy betahistine (p < .01). The vestibulospinal parameter lateral sway (Unterberger's test) improved to a significantly greater extent in patients taking the fixed combination as compared to those receiving placebo (p < .001). No serious adverse event was reported in any therapy group. The tolerability of the fixed combination was judged as very good or good by 91% (betahistine, 73%; placebo, 82%). In conclusion, the fixed combination proved to be statistically more effective than the common antivertiginous drug betahistine in reducing vertebrobasilar insufficiency-associated vertigo symptoms.

    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.

    Full Text Available Vertigo is a common clinical problem that is challenging to diagnose and treat. While it has a broad range of aetiologies, the association between vestibular disturbance and anxiety is well established. The Vertigo Symptom Scale (VSS is a questionnaire that assesses both dizziness and dizziness-related anxiety. The aim of this study was twofold. First, a translation of the VSS into Afrikaans was evaluated using the Delphi technique. Consensus was achieved within the Delphi rounds and a final tool was agreed upon. Second, the Afrikaans Vertigo Symptom Scales (AVSS was piloted on a sample of vertiginous and control participants. The results of the pilot study yielded significant statistical differences between the groups on both subscales of the tool (vertigo symptom scale and anxiety and autonomic symptom scale. Results suggest that the AVSS is able to identify patients with vertiginous disturbance and anxiety. The AVSS presents with good sensitivity and specificity as measured by the ROC curve. Clinical implications are discussed.

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.

    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

    The very rare benign chondroblastoma occasionally invades soft tissues and may grow beyond the epiphysis into the metaphysis. In the present case such a tumour did not show the typical radiological appearances, but presented malignant features both on plain films and on the angiogram. The importance of biopsy of tumours which cannot be identified with certainty must be stressed before radical surgery is carried out.

    Benign Prostatic Hyperplasia (BPH) is one of the commonest medical conditions affecting the geriatric male population. The enlargement of prostate can lead to various clinical symptoms like difficulty in voiding, urinary retention etc. The symptoms are varied depending on the size of enlargement. The International Prostatic Symptom Score (IPSS) is the gold standard and first step in understanding and diagnosing the disease clinically, but in the recent past there are various other newer tools...

    Indeterminate cell histiocytosis (ICH) is a rare, heterogeneous disorder that is characterized by immunophenotypic features of both Langerhans cell histiocytosis (LCH) and non-LCH. We describe a 12-month-old boy with a four-month history of asymptomatic, small, pink-tan papules on his face. Histopathologic evaluation showed a superficial, dermal infiltrate of histiocytes that was positive for S100, CD1a, CD68, and Factor XIIIa. To our knowledge, this represents the first report of the clinical presentation of benign cephalic histiocytosis with immunohistochemical findings of ICH. We review the classification of histiocytic disorders and the clinical and immunohistochemical features of both ICH and benign cephalic histiocytosis.

  19. Benign tumours of the vulva

    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)

    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

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

    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

    Full Text Available Objective. Discuss complex interplay of pathophysiological effects of cerebellar space occupying lesions on the vestibular pathway. Discuss challenges of diagnosis and referral along with differential and final diagnosis of unusual presentation. Case Report. We describe the case of a patient with vertiginous symptoms complicated by neurological features, namely, head titubation and tremor. The patient also had signs of oscillopsia and possible impairment of the vestibulo-ocular reflex. The resulting symptom and sign complex made for a difficult diagnosis, as the interplay of the pathophysiology of these signs, were unusual. Conclusion. The discussion has revealed that the cerebellar lesions themselves may have simultaneously caused head tremor and an inability for the vestibulo-ocular reflex to compensate, resulting in vertigo. However, whether the vertigo was a result of an oscillopsia, nystagmus, or central cause, the referral route should initially be via a general physician to rule out such a life threatening cause as a tumour.

    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.

  12. 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)

    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.

    Full Text Available Histiocytomas constitute a large group of tumors, the classification of which created a lot of confusion in the past. For this reason, various attempts were carried out during the last years so that a widely accepted classification system could be defined. Fibroxanthomas, according to contemporary data, are classified into benign histiocytomas and they are mostly located at the skin of extremities. They are rarely localized in the area of the head and neck, where they are found commonly in soft tissue. Fibroxanthomas located at the bones of oral and maxillofacial region are extremely rare. The purpose of this paper is to present a case of a fibroxanthoma located at the mandible as well as to analyze the histological findings of the lesion on which the diagnosis and differential diagnosis were based.

    1981-03-01

    A review was performed of the computed tomograms (CTs) of 500 children which had been reported as showing widening of the supratentorial subarachnoid spaces with normal cerebral substance. On the basis of this a radiological diagnosis of cerebral atrophy had been made in all but five, who were said to have mengalencephaly. From these, the children with large or abnormally enlarging heads, but normal or only slightly enlarged ventricles, were selected; there were 40 such cases (8%). The clinical condition either improved or remained stable over a period of 2 years; in the majority the scan abnormality regressed (22.5%) or remained static (67.5%). In three cases there was slight progression of the CT changes before stabilisation, but only one case developed classical communicating hydrocephalus necessitating a shunt procedure. This condition is a generally benign and mild form of communicating hydrocephalus, for which an aetiological factor was apparent in about two-thirds of the cases studied.

    This paper presents a hybrid method for design of environmentally benign processes. The hybrid method integrates mathematical modelling with heuristic approaches to solving the optimisation problems related to separation process synthesis and solvent design and selection. A structured method...... of solution, which employs thermodynamic insights to reduce the complexity and size of the mathematical problem by eliminating redundant alternatives, has been developed for the hybrid method. Separation process synthesis and design problems related to the removal of a chemical species from process streams...... because of environmental constraints are particularly suited for solution with the hybrid method. Application of the hybrid method is highlighted through two illustrative examples. The first example involves the determination of an optimal flowsheet for the removal of a chemical species from an azeotropic...

    Most of the benign intracranial tumors are meningiomas, vestibular schwannomas, pituitary adenomas, craniopharyngiomas, and glomus tumors. Some of them grow very slowly, and can be observed without specific treatment, especially if they are asymptomatic. Symptomatic or growing tumors are treated by surgery, which is the reference treatment. When surgery is not possible, due to the location of the lesion, or general conditions, radiotherapy can be applied, as it is if there is a postoperative growing residual tumor, or a local relapse. Indications have to be discussed in polydisciplinary meetings, with precise evaluation of the benefit and risks of the treatments. The techniques to be used are the most modern ones, as multimodal imaging and image-guided radiation therapy. Stereotactic treatments, using fractionated or single doses depending on the size or the location of the tumors, are commonly realized, to avoid as much a possible the occurrence of late side effects.

    corresponding auxiliary examination results, such as imaging of the nervous system and cerebrovascular assessment. In order to evaluate anxiety or depression state, methods of Self-rating Anxiety Scale (SAS), Self-rating Depression Scale (SDS) were adopted. Besides, Stroke Risk Score (SRS) was used to screen risk factors. Results In 171 cases, there were 19 patients (11%) caused by posterior circulation ischemia, 142 patients (83%) caused by peripheral vestibular vertigo, and 10 patients (6%) caused by anxiety or depression. There were no significant differences in clinical manifestations (position induced or aggregated vertigo, nausea and vomiting, nystagmus, tinnitus and hearing loss) among the three groups. There were statistically signiifcant differences in the onset age (P=0.001), smoking proportion (P=0.004), incidence of diabetes mellitus (P=0.023), hypertension (P=0.015), coronary heart disease (P=0.021), high density lipoprotein cholesterol (P=0.002), history of transient ischemic attack/stroke (P=0.006) and the rate of SRS>7 (P7 (P=0.003) were significantly higher in the central vertigo group compared with that of anxiety/depression group. Besides, the incidence of high density lipoprotein cholesterol was significantly higher in the peripheral group compared with that of anxiety/depression group (P=0.001). Conclusion Isolated vertigo are mainly non-central vascular vertigo, while acute cerebrovascular disease (mostly of posterior circulation ischemia) can be characterized by isolated vertigo. There are signiifcant differences in the onset age, history of stroke risk factors between the central and non-central vertigo. In the clinical diagnosis and treatment we should focus on identifying central damage to avoid serious consequences.

    To evaluate the diagnostic accuracy of a new ultrasound (US) classification system for differentiating between benign and malignant solid thyroid nodules. In this study, we enrolled 191 consecutive patients who received real-time US and subsequent US diagnoses for solid thyroid nodules, and underwent US-guided fine-needle aspiration. Each thyroid nodule was prospectively classified into 1 of 5 diagnostic categories by real-time US: 'malignant,' 'suspicious for malignancy,' 'borderline,' 'probably benign,' and 'benign'. We evaluated the diagnostic accuracy of thyroid US and the cut-off US criteria by comparing the US diagnoses of thyroid nodules with cytopathologic results. Of the 191 solid nodules, 103 were subjected to thyroid surgery. US categories for these 191 nodules were malignant (n = 52), suspicious for malignancy (n = 16), borderline (n = 23), probably benign (n 18), and benign (n = 82). A receiver-operating characteristic curve analysis revealed that the US diagnosis for solid thyroid nodules using the 5-category US classification system was very good. The sensitivity, specificity, positive and negative predictive values, and accuracy of US diagnosis were 86%, 95%, 91%, 92%, and 92%, respectively, when benign, probably benign, and borderline categories were collectively classified as benign (negative). The diagnostic accuracy of thyroid US for solid thyroid nodules is high when the above-mentioned US classification system is applied.

    目的:研究手法对于颈本体觉紊乱的眩晕患者的头颅空间回复能力的影响.方法:利用头颅三维空间运动测量仪,临床观察72例颈本体觉紊乱的眩晕患者手法治疗前后其头颅空间回复能力的变化.另外选取51例颈椎动脉供血不足的眩晕患者及138例正常人作对照组.结果:手法治疗后本体觉组在三个运动轴线上的头颅空间偏移度均有明显减小.结论手法有即刻改善颈本体觉功能的作用,在临床椎动脉供血不足型眩晕的发病也存在着本体觉紊乱的因素.%Purpose: To study the influence of the manual manipulations on the reversal ability of the skull space in the patients with vertigo due to proprioceptive disturbance of the neck. 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.

    Full Text Available Abstract Background Although Helicobacter Pylori (HP was detected in some cases of chronic laryngitis, the results were not confirmed by polymerase chain reaction (PCR. By this time, it has not been found in laryngeal lesions by in house PCR, the most sensitive method for detecting the genome tracks. Regarding the previous results and also few numbers of studies about the presence of HP in benign laryngeal lesions, specifically by PCR, we aimed to investigate the presence of HP in benign laryngeal lesions by in-house PCR. Methods The samples were taken from 55 patients with benign laryngeal lesions and frozen in −20°C. One milliliter (ml of lysis buffer was added to 100 mg (mg of each sample and the tube was placed in 56°C overnight. Then DNA extraction was carried out. Results To find HP DNA, in-house PCR was performed that revealed 5 positive results among 55 patients with benign laryngeal lesions. Of them, 3 were polyp, 1 was nodule and 1 was papilloma. Conclusion Although the number of positive results was not a lot in this study, it was in contrast with previous studies which could not find any HP tracks in benign laryngeal lesions by other methods. More studies about the prevalence of HP in benign laryngeal lesions improve judging about the effect of this infection on benign laryngeal lesions.

    The most important causes of recurrence of benign pleomorphic adenoma are enucleation with intraoperative spillage and incomplete tumor excision in association with characteristic histologic findings for the lesion (incomplete pseudocapsule and the presence of pseudopodia). Most recurrent pleomorphic adenomas (RPAs) are multinodular. MRI is the imaging method of choice for their assessment. Nerve integrity monitoring may reduce morbidity of RPA surgery. Although treatment of RPA must be individualized, total parotidectomy is generally recommended given the multicentricity of the lesions. However, surgery alone may be inadequate for controlling RPA over the long term. There is growing evidence from retrospective series that postoperative radiotherapy results in significantly better local control. A high percentage of RPAs are incurable. All patients should therefore be informed about the possibility of needing multiple treatment procedures, with possible impairment of facial nerve function, and radiation therapy for RPA. Reappearance of Warthin tumor is a metachronous occurrence of a new focus or residual incomplete excision of all primary multicentric foci of Warthin tumor. Selected cases can be observed. Conservative surgical management can include partial superficial parotidectomy or extracapsular dissection. Not uncommonly, other major and minor salivary gland neoplasms, including myoepithelioma, basal cell adenoma, oncocytoma, canalicular adenoma, cystadenoma, and ductal papilloma, follow an indolent course after surgical resection, with rare cases of recurrence.

    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.

    Helicobacter pylori prevalence is decreasing globally and prevalence of non H. pylori gastric ulcers is increasing. The following study was conducted to assess the prevalence of H. pylori in benign gastric ulcers in a sample of Sri Lankan patients. This was a cross-sectional study of 59 dyspeptic patients with benign gastric ulcers. Multiple endoscopic gastric biopsies were obtained and histology, immunohistochemistry and polymerase chain reaction were performed for H. pylori detection. An immunochromatography assay was performed to detect blood anti H. pylori antibodies. Four (6.8%) were positive for H. pylori. Therefore, it is likely that most benign gastric ulcers are of non-H. pylori aetiology.

  10. 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

    Lower UrinaryTracts Symptoms (LUTS) due to Benign Prostatic Hyperplasia (BPH) represent an increasing prevalent condition in ageing men. Patients often seek primarily consultation at their general practitioner. Aetiology and natural history of LUTS due to BPH have not been completely clarified. The development of symptomatic LUTS is age-dependent and determined to varying degrees by the presence of Benign Prostatic Hyperplasia (BPH), Benign Prostatic Enlargement (BPE) as well as Bladder Outlet Obstruction (BOO). A causal relationship does not always exist. Basis for a specific medical or surgical treatment in the individual patient with LUTS due to BPH is an exact diagnosis by the practising urologist.

    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.

    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.

    The German BMBF (German Ministry of Education and Research) has decided to establish an Integrated Center for Research and Treatment of Vertigo, Balance and Ocular Motor Disorders (IFB(LMU)) in Munich in 2010. After funding over a 10-year period, the long-term continuation of the IFB(LMU) by the medical faculty and the hospital is envisioned. Vertigo is one of the most common complaints in medicine. Despite its high prevalence patients with vertigo generally receive either inappropriate or inadequate treatment. This deplorable situation is internationally well known and its causes are multiple: insufficient interdisciplinary cooperation, no standardized diagnostics and therapy, the failure to translate findings of basic science into clinical applications and the scarcity of clinical multicenter studies. The IFB(LMU) will constitute a suitable tool with which these structural, clinical, and scientific deficits can be overcome. It will also make possible the establishment of an international interdisciplinary referral center. Munich has become the site of a unique concentration of leading experts on vertigo, balance and ocular motor disorders, both in the clinical and basic sciences. Academic structures have paved the way for the creation of an interdisciplinary horizontal network that also allows structured, vertical academic career paths via the Bachelor's and Master's degree programs in neuroscience, a Graduate School of Systemic Neurosciences, and the Munich Center for Neuroscience "Brain and Mind". The IFB(LMU) has the following objectives with regard to structure and content: to create an independent patient-oriented clinical research center under the auspices of the Medical Faculty but with autonomic administration and budget; to overcome existing clinical and academic barriers separating the traditional specializations, to establish a standardized interdisciplinary longitudinal and transversal network at one site for the management of patients.

  7. 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

    We cared for four patients with benign cephalic histiocytosis, a self-healing non-X, nonlipid cutaneous histiocytosis of children. The age of onset of the disease was 5 to 9 months, with papules and erythematous macules involving the head (mainly the cheeks), and posterior spread to the trunk and limbs in three patients. Microscopic examination of skin biopsies revealed a histiocytic infiltrate in the superficial dermis that was S100 protein-negative by immunoperoxidase (PAP method). One patient showed comma-shaped bodies and desmosomelike junctions on electron microscopy. No Birbeck's granules were present. Benign cephalic histiocytosis is a self-limiting condition that requires no treatment.

    A 16-year-old boy with rotatory positional vertigo and nausea, particularly when lying down, visited our clinic. Initially, we observed vertical/torsional (downward/leftward) nystagmus in the supine position, and it did not diminish. In the sitting position, nystagmus was not provoked. Neurological examinations were normal. We speculated that persistent torsional down-beating nystagmus was caused by the light cupula of the posterior semicircular canal. This case provides novel insights into the light cupula pathophysiology.

    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 b{sub 1,000} 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 b{sub 1,000} 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 b{sub 1,000} diffusion-weighted images were benign. Alternatively, the presence of a solid component with intermediate T2 signal and high b{sub 1,000} 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.)

    Full Text Available Background: Using of CD10 in accordance with clinical and histological features of thyroid lesions could be used as both diagnostic and prognostic tool, which consequently influence the management and their prognosis for survival of patients with thyroid neoplasms especially papillary thyroid carcinoma (PTC. The aim of this study was to determine its expression in PTC and different benign thyroid lesions. Materials and Methods: In this descriptive-analytic, cross-sectional study, paraffin-embedded tissues of patients with definitive pathologic diagnosis of different benign thyroid lesions and PTC were retrieved. Immunostained sections of each slides was performed using immunohistochemistry methods and expression of CD10 was compared in two groups of benign thyroid lesions and PTC. Results: From selected cases 134 sections studied in two groups of PTC (n = 67 and benign thyroid lesions (n = 67. CD10 were immunohistochemically positive in 29.9% of PTC cases, but in none of the thyroid benign lesions (0% (P 0.05. Conclusion: The results of the current study indicate that due to the higher expression of CD10 in PTC than benign thyroid lesions it might be used for differentiating mentioned lesions. But for using it as a diagnostic tool further studies with larger sample size and determination of its sensitivity, specificity and cut-off point is necessary.

    Sudden sensorineural hearing loss (SSNHL) is a decrease in hearing of at least 30 dB that occurs within three days and which affects at least three consecutive frequencies in either ear or both ears. This case report describes a woman who had sudden hearing loss and vertigo in the right ear after tooth extraction. As the first-line therapy, systemic and intratympanic steroid injections were used this led to a slight improvement; however, the majority of improvement in hearing was not observed until hyperbaric oxygen (HBO2) therapy was instituted on the 20th day of hearing loss. Sudden hearing loss and vertigo after tooth extraction is an otologic emergency and early evaluation and treatment are effective. HBO2, although employed beyond the Undersea and Hyperbaric Medical Society's recommended initial 14 days of symptom onset, very was effective for this particular case.

    Full Text Available Abstract Background Dizziness and comorbid anxiety may cause severe disability of patients with vestibulopathy, but can be addressed effectively with rehabilitation. For an individually adapted treatment, a structured assessment is needed. The Vertigo Symptom Scale (VSS with two subscales assessing vertigo symptoms (VSS-VER and associated symptoms (VSS-AA might be used for this purpose. As there was no validated VSS available in German, the aim of the study was the translation and cross-cultural adaptation in German (VSS-G and the investigation of its reliability, internal and external validity. Methods The VSS was translated into German according to recognized guidelines. Psychometric properties were tested on 52 healthy controls and 202 participants with vestibulopathy. Internal validity and reliability were investigated with factor analysis, Cronbach’s α and ICC estimations. Discriminant validity was analysed with the Mann–Whitney-U-Test between patients and controls and the ROC-Curve. Convergent validity was estimated with the correlation with the Hospital Anxiety Subscale (HADS-A, Dizziness Handicap Inventory (DHI and frequency of dizziness. Results Internal validity: factor analysis confirmed the structure of two subscales. Reliability: VSS-G: α = 0.904 and ICC (CI =0.926 (0.826, 0.965. Discriminant validity: VSS-VER differentiate patients and controls ROC (CI =0.99 (0.98, 1.00. Convergent validity: VSS-G correlates with DHI (r = 0.554 and frequency (T = 0.317. HADS-A correlates with VSS-AA (r = 0.452 but not with VSS-VER (r = 0.186. Conclusions The VSS-G showed satisfactory psychometric properties to assess the severity of vertigo or vertigo-related symptoms. The VSS-VER can differentiate between healthy subjects and patients with vestibular disorders. The VSS-AA showed some screening properties with high sensitivity for patients with abnormal anxiety.

    To study the expression and significance of the serine protease Omi/HtrA2 in prostate cancer and benign prostatic hyperplasia. The expression of Omi/HtrA2 was assayed by means of immunohistochemical technique in 41 prostate cancer (Cap), 20 benign prostatic hyperplasia (BPH) and 10 normal prostate (NP) specimens. Omi/HtrA2 expression was positive in 30 (73.17%) prostate cancer specimens, and the positive rate of Omi/HtrA2 was lower in well differentiated than in poorly and moderately differentiated groups (P<0.05). By contrast, the cells in normal prostate and benign prostatic hyperplasia groups showed no or weak expression of Omi/HtrA2.Prostate cancer cells in vivo may need Omi/HtrA2 expression for apoptosis, and that Omi/HtrA2expression might be involved in prostate cancer development.

    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.

    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.

  12. 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

    Full Text Available Abstract Introduction Retroperitoneal cysts are uncommon, with an estimated incidence of 1/5750 to 1/250,000. Case presentation A male patient was admitted with an abdominal pain, jaundice and fever. Clinical examination and investigations confirmed an idiopathic benign retroperitoneal cyst. He underwent surgery and was discharged after making good recovery. Conclusion Retroperitoneal cysts are very rare, and most of the time they are discovered incidentally. Patients may be asymptomatic or present with abdominal pain, referred pain to the legs or weight loss. Imaging may help diagnose these lesions, but surgery is the keystone in confirming the diagnosis. This case is very rare and very educational as it highlights an unusual presentation of a benign retroperitoneal cyst. In our patient, the course of the disease was unique as the patient presented with jaundice.

    2007-01-01

    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.

    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.

    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.

    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.

    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

    Understanding particle dynamics in the 'Twilight Zone' is critical to prediction of the ocean's carbon cycle. As part of the VERtical Transport In the Global Ocean (VERTIGO) 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 ˜100 high-frequency CTD/transmissometer/turbidity sensor profiles. VERTIGO studies lasting 3 weeks, contrasted oligotrophic station ALOHA (22.75°N 158°W), sampled in June-July 2004, with a biologically productive location (47 °N 161°E) near station K2 in the Oyashio, occupied July-August 2005. Profiles of major and minor particulate components (C org, N, P, Ca, Si, Sr, Ba, Mn) in 51 μm size fractions, in-water optics, neutrally buoyant sediment trap (NBST) fluxes, and zooplankton data were intercompared. MULVFS total C org and C-Star particle beam attenuation coefficient ( C P) were consistently related at both sites with a 27 μM m -1 conversion factor. At K2, C 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 ˜40% and 10%, night and day, respectively to >51 μm C 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 μm C org, N, and P at both ALOHA and K2 showed strong attenuation with depth at both sites. Notable at ALOHA were unusually high levels of >51 μm Sr (up to 4 nM) in the mixed layer, a reflection of high abundances of SrSO 4 precipitating Acantharia. Notable at K2 were major changes in water column inventories of many particulate components to 700 m over 10 days

    Spatial Contrast Sensitivity (CS) was studied in 20 patients with benign intracranial hypertension (BIH). At presentation CS loss was found in 43% of the eyes, and impairment of visual acuity attributed to BIH in only 16%. Nine patients had blurred vision or visual obscurations, all of whom had abnormal CS. The clinical application of CS measurement in BIH for monitoring the progression or regression of the disease is illustrated by serial measurements in 11 patients. Progressive visual loss in longstanding papilloedema and improvement of visual function in subsiding papilloedema can occur without any change in Snellen acuity or visual field charting.

    Full Text Available Transurethral prostate resection is still accepted as golden standard treatment modality for the management of benign prostate hyperplasia (BPH. Laser represents the most promising option among the minimal invasive alternatives. Laser with different wavelengths can provide coagulation, enucleation or vaporization on the target tissues. The significant advantages of laser applications are lesser complication rates of mainly retrograde ejaculation and erectile dysfunction, shorter hospitalization and catheterization times, and applicability in patients on anticoagulant treatment. However, further randomized multicenter trials are certainly required for laser to become a candidate for golden standard treatment for BPH.

    Endoscopic management of biliary obstruction has evolved tremendously since the introduction of flexible fiberoptic endoscopes over 50 years ago. For the last several decades, endoscopic retrograde cholangiopancreatography(ERCP) has become established as the mainstay for definitively diagnosing and relieving biliary obstruction. In addition, and more recently, endoscopic ultrasonography(EUS) has gained increasing favor as an auxiliary diagnostic and therapeutic modality in facilitating decompression of the biliary tree. Here, we provide a review of the current and continually evolving role of gastrointestinal endoscopy, including both ERCP and EUS, in the management of biliary obstruction with a focus on benign biliary strictures.

    Benign symmetric lipomatosis(BSL) is a rare disease characterized by the presence of multiple, symmetric and nonencapsulated fat masses in the face, neck and other areas. It is commonly seen in middle-aged Caucasian Mediterranean males, while its etiology is still not clear. The majority of the patients with BSL have a history of alcohol abuse and hepatopathy. BSL of the limbs is very rare. This article reports a unique case of a 60-year-old Chinese woman with involvement of the knees confirmed by the results of magnetic resonance imaging(MRI) and histopathology, which was not described previously in published literatures.

    Full Text Available Benign intracranial hypertension is characterized with increase in CSF opening pressure with no specific etiology. It is predominantly found in women of child bearing age and particularly in individuals with obesity. Visual disturbances or loss and associated headaches are common and can lead to blindness if left untreated. Diagnosis can be achieved once other causes of visual loss, headaches and high opening pressures are excluded. Management consists of serial optic disc assessments although no specific treatment is available despite recent trials using carbonic anhydrase inhibitors. Diet modification and weight management can help in therapy.

    Earlier this year, tamsulosin, an alpha blocker previously only available on prescription, became available for sale by pharmacists as a treatment for functional symptoms of benign prostatic hyperplasia (BPH) in men aged 45-75 years (Flomax Relief MR - Boehringer Ingelheim). A television advert for the over-the-counter (OTC) product claims that it is a "simple and effective" treatment that can relieve symptoms within 1 week, allowing the user to "take control of your annoying pee problems".¹ Here we review the evidence on tamsulosin and assess whether its availability as an OTC product confers worthwhile advantages.

    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 ( Teff) 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 suspended and sinking

    Full Text Available Case summary A 10-year-old castrated male domestic shorthair cat was presented for assessment of a gingival mass surrounding the left maxillary third and fourth premolar teeth. The mass was surgically removed by means of a marginal rim excision, and the tissue was submitted for histological assessment. It was identified as a benign cementoblastoma (true cementoma. There was proliferation of mineralized eosinophilic material with multiple irregularly placed lacunae and reversal lines, reminiscent of cementum. The cat recovered uneventfully from the anesthesia, and there was no evidence of tumor recurrence 6 months after surgery. Relevance and novel information Cementoblastomas (true cementomas in domestic animals are rare, with just a few reports in ruminants, monogastric herbivores and rodents. Cementoblastoma is considered a benign tumor that arises from the tooth root. The slow, expansive and constant growth that characterizes these masses may be accompanied by signs of oral discomfort and dysphagia. This case report is intended to increase knowledge regarding this tumor in cats and also highlights the importance of complete excision of the neoplasm. To our knowledge, there are no previous reports in the literature of cementoblastoma in the cat.

    We studied CT patterns in 21 cases of primary benign retroperitoneal tumor including teratoma in nine cases, schwannoma in six, leiomyoma in three, lipoma in one, lymphangioma in one, and neurofibroma in one. The tumors were analyzed for size, internal homogeneity, CT density, calcification, border with neighboring organs, and contrast enhancement (CE). The mean diameter of the tumors was 10.2 ([+-]4.8) cm. Internal homogeneous distribution was observed in 33%, calcification in 43%, and well-defined border in 86%. The CT density and calcification were compared according to histology, and the results were as follows: teratoma showed fat density in 78%, water density in 100%, and calcification in 89%; schwannoma showed water density in 100% and septal CE in 33%; leiomyoma showed soft tissue density in 100%, CE in 100%, and water density in 33%; lipoma showed fat density and calcification; and lymphangioma and neurofibroma showed water density. Internal homogeneity, fat density, cyst formation, and calcification are considered to be important predictors of primary benign retroperitoneal tumor on CT. (author).

    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.

    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”。

    Objectives: To assess the association of adenomyotic foci with co-existing benign ovarian cysts. Methods: This prospective cross-sectional study consisted of 100 consecutive hysterectomy specimens referred to Histopathology Section of Pathology Department, Peshawar Medical College, Peshawar, Pakistan by its attached teaching hospitals from January 2011 to December 2012. Hematoxylin and eosin stained sections were examined for adenomyotic foci and the presence of co-existent ovarian cysts. For evaluation of estrogen receptor (ER) status immunohistochemical stains were applied and H-scoring system was used with a score >50 as positive. Results: Out of the 100 hysterectomy specimens, 25 cases had both adenomyosis and ovarian cysts. The ER status of adenomyotic foci was positive in 20% cases and negative in 80% cases. The commonest type of ovarian cyst was hemorrhagic luteal cyst (28%), followed by serous and mucinous cystadenoma (20%) each. Out of the 28% cases of functional cysts, 71.5% were ER positive and 28.5% were ER negative. The p-value for association of ER status of adenomyotic foci with functional cysts was 0.0004; however, p-value was not significant in comparing cases with controls. All 72% cases of nonfunctional cysts were ER negative. However, 44% of functional cysts were not associated with adenomyotic foci. Conclusion: This study concludes that besides functional ovarian cysts, other local factors may be responsible for the development of adenomyosis. PMID:27570851

    The purpose of this study is to evaluate the accuracy of differentiation between benign and malignant clustered microcalcifications without mass on mammogram. Fourty six mammograms of 44 patients showing clustered microcalcifications without mass were interpreted blindly by five independent observers majoring in breast imaging from different institutions. Twenty two were malignant (10 infiltrating ductal carcinomas, 12 intraductal carcinomas) and 24 were benign (all fibrocystic disease). The observers judge benignancy or malignancy of microcalcifications. The authors assess the accuracy of differential diagnosis of clustered microcalcifications. Of 24 cases proved benign microcalcifications, five radiologists correctly interpreted 20 on average as benign and of malignant 22 cases, 16 on average were correctly interpreted as malignant. The diagnostic accuracy of malignant microcalcifications was 71.8% on average(63.6%{approx}81.8%) and the diagnostic accuracy for benign microcalcifications was 83% on average(71%{approx}92%). It was 9 among total 46 cases that were misinterpreted by more than three radiologists. Among these 9 cases, malignant microcalcifications that had been misinterpreted as benign were seven, benign microcalcifications misinterpreted as malignant were two. The diagnostic accuracy of clustered malignant microcalcifications(71.8%) without mass on mammogram was lower than that of benign microcalcifications(83.3%). So, in case of suspected malignant microcalcification on mammogram, it is preferable that along with magnification view, histopathologic confirmation by core biopsy must be obtained.

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

    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

    Benign biliary strictures are a common indication for endoscopic retrograde cholangiopancreatography (ERCP). Endoscopic management has evolved over the last 2 decades as the current standard of care. The most common etiologies of strictures encountered are following surgery and those related to chronic pancreatitis. High-quality cross-sectional imaging provides a road map for endoscopic management. Currently, sequential placement of multiple plastic biliary stents represents the preferred approach. There is an increasing role for the treatment of these strictures using covered metal stents, but due to conflicting reports of efficacies as well as cost and complications, this approach should only be entertained following careful consideration. Optimal management of strictures is best achieved using a team approach with the surgeon and interventional radiologist playing an important role.

    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

    Angiomyolipomas are benign neoplasms composed of smooth muscle, vasculature, and mature adipose tissue, which most commonly occur in the kidney and located in the head and neck region. A very rare neoplasm, there are only 3 cases of angiomyolipoma in the parotid gland that have been reported to date. Here, we report a case of a 38-year-old man who had a slow-growing mass in the parotid gland for the past 7 years. The results of a physical examination revealed a rubbery mass that was 2.5 cm in diameter in the below superficial lobe of the left parotid gland. A computed tomographic scan showed a heterogeneous and lobulated nodule with a well-defined margin, which was resected through partial parotidectomy with preservation of the facial nerve. A histologic finding revealed an angiomyolipoma of the parotid gland. In conclusion, angiomyolipoma should be considered in the differential diagnosis of rubbery parotid gland masses.

    Gastroesophageal reflux disease (GERD) and esophageal achalasia are common benign esophageal diseases. Today minimally invasive surgery is recommended to treat these diseases. Surgical indications for GERD are failure of medical management, medical complications attributable to a large hiatal hernia, 'atypical' symptoms (asthma, hoarseness, cough, chest pain, aspiration), etc. according to the Society of American Gastrointestinal Endoscopic Surgeons (SAGES) guidelines. Laparoscopic Nissen fundoplication has emerged as the most widely accepted procedure for GERD patients with normal esophageal motility. Partial fundoplication (e.g., Toupet fundoplication) is also considered to decrease the possibility of postoperative dysphagia. Although pneumatic dilatation has been the first line treatment for esophageal achalasia, laparoscopic Heller myotomy and partial fundoplication (e.g., Dor fundoplication) to prevent reflux is preferred by most gastroenterologists and surgeons as the primary treatment modality. Laparoscopic surgery for GERD and esophageal achalasia are effective in most patients and safe in all patients. Finally, laparoscopic surgery should be performed only by skilled surgeons.

  18. 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. This study also suggests the possibility of different time patterns of risk between different cancers. (U.K.).

    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

    Full Text Available Introduction. Mature teratomas (benign cystic teratomas or dermoid cysts are among the most common ovarian tumours; however, teratomas of the omentum and mesentery are extremely rare. Teratoma in the intraperitoneal cavity is uncommon and atypical, and it is even more uncommon in adulthood. Case Outline. An 82-year-old female was admitted to our department with clinical signs of abdominal tumour. The ultrasound scan and preoperative laboratory tests were done. Explorative laparotomy revealed tumour with torsion on its pedicle at the greater omentum. After removal of the mass and the incision a tooth and hair were found, characteristics of teratoma. Conclusion. The excision was very effective and also definitive treatment for this case. The patient recovered well and was discharged 3 days later. The patient probably carried the tumour all her life asymptomatically until admission.

Most frequently the condition presents with signs ofmalabsorption such as weight loss and diarrhea, but other symptoms include nausea, vomiting (sometimeswith fecal, and abdominal pain. Gastrointestinal inflammatory conditions are the usual causes. The mostcommon ones are perforated duodenal ulcer and Crohn’s disease. Barium enemas are usually diagnostic.Treatment consists of excising the fistula and repairing the duodenal and colonic defects. Closure of thefistula provides quick relief.

    The debate over the role of the da Vinci surgical robotic platform in benign gynecology is raging with increasing fervor and, as product liability issues arise, greater financial stakes. Although the best currently available science suggests that, in the hands of experts, robotics offers little in surgical advantage over laparoscopy, at increased expense, the observed decrease in laparotomy for hysterectomy is almost certainly, at least in part, attributable to the availability of the robot. In this author's opinion, the issue is not whether the robot has any role but rather to define the role in an institutional environment that also supports the safe use of vaginal and laparoscopic approaches in an integrated minimally invasive surgery program. Programs engaging robotic surgery should have a clear and self-determined regulatory process and should resist pressures in place that may preferentially support robotics over other forms of minimally invasive surgery.

    眩晕是临床上常见症状之一,椎-基底动脉系统血流减少是眩晕发生的常见原因之一.而椎动脉优势可产生不对称的血流模式,对血管壁产生不对称的机械作用力,从而加重血管动脉粥样硬化,促使血管狭窄,影响椎-基底动脉系统的血流动力学,使椎基底动脉系统血液供应减少,导致眩晕的发生.现就椎动脉优势与眩晕关系的研究进展予以综述.%Vertigo is one of the common clinical symptoms. Blood flow reduction in vertebral-basilar artery system is one of the common causes of vertigo. Vertebral artery dominance can produce asymmetric blood flow patterns, which generates asymmetric mechanical forces on the arterial wall, aggravating atherosclerosis and prompting vascular stenosis , which may affect the hemodynamics of vertebrobasilar system and decrease the blood flow in the system resulting in vertigo. This review focuses on research progress of the relationship between vertebral artery dominance and vertigo.

  7. 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

    Full Text Available Context: The c-erbB-2 proto-oncogene is a member of the epidermal growth factor receptor family and has been associated with a more aggressive breast tumor biology and resistance to some types of treatments. 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.

    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.

    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.

    Cases of radiation therapy for benign diseases have diminished in number because of recent alternative methods and knowledge about radiation carcinogenesis. In contrast to this tendency, our cases of benign diseases have recently increased. The facts made us reconsider today's radiation therapy of benign diseases. We reviewed 349 patients who were diagnosed as having benign tumors or non-neoplastic conditions and treated by radiation therapy in the past sixteen years. Analyzed items were the annual transition of treatment number, sorts of diseases, patients' age and sex, and the goal of therapy. Of all radiation therapy patients, benign diseases account for 9.26%. The annual percentages were 0.5%, 6.0%, 11.2% and 13.7% at intervals of five years since 1982. The majority was 246 post-operative irradiation for keloids (71%) and 41 pituitary adenomas (12%). Compared with malignant tumors, benign disease patients were statistically younger and female-dominant. Applications of radiation therapy in keloids and pituitary adenomas had definite goals, but were unclear in other rare diseases. Benign diseases should be treated by radiation therapy as the second or third option, provided the patients have serious symptoms and their diseases do not respond to other modalities. It seems to be widely accepted that favorite cases such as keloids and pituitary adenomas are treated by radiation therapy. But, optimal radiation therapies for other rare benign diseases have not been established. Therefore, the building of databases on radiation therapy on benign diseases should be pursued. Since benign disease patients were young and female-dominant and had many remaining years, their carcinogenicity potential should be considered. (author)

    We investigated the feasibility of using texture features extracted from mammograms to predict whether the presence of microcalcifications is associated with malignant or benign pathology. Eighty-six mammograms from 54 cases (26 benign and 28 malignant) were used as case samples. All lesions had been recommended for surgical biopsy by specialists in breast imaging. A region of interest (ROI) containing the microcalcifications was first corrected for the low-frequency background density variation. Spatial grey level dependence (SGLD) matrices at ten different pixel distances in both the axial and diagonal directions were constructed from the background-corrected ROI. Thirteen texture measures were extracted from each SGLD matrix. Using a stepwise feature selection technique, which maximized the separation of the two class distributions, subsets of texture features were selected from the multi-dimensional feature space. A backpropagation artificial neural network ANN) classifier was trained and tested with a leave-one-case-out method to recognize the malignant or benign microcalcification clusters. The performance of the ANN was analysed with receiver operating characteristic ROC) methodology. It was found that a subset of six texture features provided the highest classification accuracy among the feature sets studied. The ANN classifier achieved an area under the ROC curve of 0.88. By setting an appropriate decision threshold, 11 of the 28 benign cases were correctly identified (39% specificity) without missing any malignant cases (100% sensitivity) for patients who had undergone biopsy. This preliminary result indicates that computerized texture analysis can extract mammographic information that is not apparent by visual inspection. The computer-extracted texture information may be used to assist in mammographic interpretation, with the potential to reduce biopsies of benign cases and improve the positive predictive value of mammography.

    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.

    The aim of this study was to evaluate the diagnostic utility of the virtual touch tissue quantification (VTQ) technology for differentiating between benign and malignant thyroid nodules. 198 nodules (168 benign and 30 malignant nodules) identified in 164 patients with available VTQ velocity data and fine-needle aspiration cytology or post-surgical pathological results were included. The VTQ velocities of nodules and adjacent thyroid tissue were examined. Malignant nodules had a significantly higher VTQ velocity (3.06 ± 1.04 m/s, range: 1.90-6.46 m/s) than that of benign nodules (2.40 ± 0.85 m/s, range: 0.69-8.09 m/s) (p = 0.002). The VTQ velocity ratio between malignant nodules and adjacent thyroid tissue (1.39 ± 0.43, range: 0.89-2.65) was also statistically higher than that of benign nodules (1.15 ± 0.44, range: 0.26-3.47) (p = 0.008). The area under the receiver operating characteristic curve for the VTQ velocity was 0.72 with a cutoff point of 2.37 m/s and that of the VTQ velocity ratio was 0.68 with a cutoff point of 1.26. The sensitivity, specificity, positive predictive value, negative predictive value, and accuracy for the VTQ velocity were 86.7%, 50.6%, 23.9%, 95.5%, and 56.1%, respectively and 60.0%, 72.0%, 27.7%, 91.0%, and 70.2%, respectively for the VTQ velocity ratio. VTQ may be helpful in differentiating malignant and benign thyroid nodules with high negative predictive value.

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.

    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 To study the mechanism and feasibility of transurethral electrochemical therapy for the treatment of benign prostatic hyperplasia (BPH). Methods Between March 1998 and March 2000, specifically designed devices and catheters for electrochemical therapy were applied to 6 prostate specimens obtained by suprapubic prostatectomy in order to treat BPH patients with urinary retention for whom surgery was contraindicated. Sixteen patients (with a mean age of 77.3 years old) underwent electrical treatment totaling 160-220 coulombs under topical urethral anesthesia for 68-132 min. The catheters remained inside the patient for 7-10 d. Results Irreversible destructive changes occurred within cathodal tissue, while carbonization occurred within anodic tissue. The radius of tissue change was 7-8 mm and 1-2 mm, respectively. In vivo trial: 11 (69%) patients could be weaned off the catheters with satisfactory urination. Three months after therapy, the mean international prostate symptom score (IPSS) was 14.5, mean peak flow rate was 10.5 ml/s, and mean residual urine was 39 ml. No serious complications were observed. Conclusion Transurethral electrochemical treatment is potentially a minimally invasive alternative for treatment of BPH, especially for elderly patients at high risk.

    A survey of 67 pregnancies in 51 professional women (physicians, psychologists, nurses, administrators, etc.) revealed the occurrence of symptoms of cognitive dysfunction such as forgetfulness, disorientation, confusion and reading difficulties in 28 pregnancies occurring in 21 women. These were unrelated to such factors as age of delivery, percentage weight gain, the baby's sex or birth weight, alcohol consumption, smoking, a history of migraine or allergy or other symptoms occurring during pregnancy such as sleepiness and lack of concentration, irritability, loss of interest in job or nightmares. Nor was there any correlation with hypertension, proteinuria, glycosuria, ketonuria, anemia, or morning sickness. Furthermore, these cognitive disturbances were not related to depression or sleep deprivation. Despite these symptoms, none of the women suffering from them were forced to interrupt their professional activities during pregnancy. The syndrome of benign encephalopathy of pregnancy should be recognized so that simple precautions can be taken to prevent any interference with professional or other activities. The etiology of the syndrome is unknown.

    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

    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.

    Botulinum toxin (BoNT) has been increasingly used in the interventional treatment of several disorders; the use of this agent has extended to a plethora of conditions including focal dystonia, spasticity, inappropriate contraction in most gastrointestinal sphincters, eye movement disorders, hyperhidrosis, genitourinary disorders and aesthetically undesirable hyperfunctional facial lines. In addition, BoNT is being investigated for the control of pain, and for the management of tension or migraine headaches and myofascial pain syndrome. Benign prostatic hyperplasia (BPH) is a common condition in ageing men; the goal of therapy is to reduce the lower urinary tract symptoms (LUTS) associated with BPH and to improve the quality of life. However, medical treatment, including drugs that relax smooth muscle within the prostate and drugs that shrink the gland are not totally effective or without complications. The standard surgical treatment for BPH is progressively changing to minimally invasive therapies, but none of them has provided clear results. The use of BoNT-A to inhibit the autonomic efferent effects on prostate growth and contraction, and inhibit the abnormal afferent effects on prostate sensation, might be an alternative treatment for BPH. BoNT injections have several advantages over drugs and surgical therapies in the management of intractable or chronic disease; systemic pharmacologic effects are rare, permanent destruction of tissue does not occur, and graded degrees of relaxation may be achieved by varying the dose injected. In this paper, clinical experience over the last years with BoNT in BPH impaired patients will be illustrated.

  9. Transurethral microwave thermotherapy for benign prostatic hyperplasia

    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.

    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)

    Phyllodes tumors (PT) are uncommon fibroepithelial breast neoplasms and there is currently no clear consensual treatment for these tumors. The aim of our study was to evaluate the surgical management and outcome of benign and borderline PT. We retrospectively assessed 76 cases of benign or borderline PT managed at the Leon Berard comprehensive cancer center in Lyon, France between July 2003 and December 2013. The mean age at diagnosis was 37.9 years and the median follow-up was 58 months. Seventy-five patients (99%), with a mean tumor size of 27 mm, underwent a breast-conserving procedure. The tumor margins were considered positive (when the tumor was present at the inked surgical section) in seven of 76 cases (9%) and negative in 65 out of 76 cases (86%). We observed the presence of small negative surgical margins <10 mm in 89% and <1 mm in 71% of the patients. Although no re-excision was performed to increase these margins, we did not see any increase in the local recurrence rate (4%) when compared to recurrence rates reported in the literature. We thus suggest that systematic revision surgery for close or positive surgical margins for benign PT should not be systematically performed. However, as recurrences occur within 2 years of initial excision, we recommend a regular clinical and imaging follow-up especially during this period for which patient's compliance is essential.

    2012-07-01

    A 56-year-old patient was referred for FDG PET/CT with a right preauricular lymph node fine-needle biopsy, suggesting poorly differentiated carcinoma and no obvious primary lesion. There was intense FDG uptake in the right preauricular nodule. The node was excised, and formal histology demonstrated a benign pilomatricoma rather than malignancy. Pilomatricoma is uncommon in adults and an unusual cause for marked FDG uptake, likely due to foreign body inflammation. Pilomatricoma can be either benign or malignant. The marked FDG uptake demonstrated in our patient with benign pilomatricoma also suggests that FDG PET cannot reliably grade this rare condition.

    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

    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 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

    To study the expression of beta-human chorionic gonadotropin (βhCG) genes in renal cellcarcinomas (RCC) and benign renal disease tissues, nested reverse transcription-polymerase chainreaction (RT-PCR) and restriction endonuclease analysis were employed to detect the expression ofβhCG genes in 44 cases of RCC tissues and 24 cases of benign renal disease tissues. It was foundthat 52% RCC samples revealed positive for βhCG mRNA expression. Positive rate in advancedstage and poorly differentiated RCC was higher, but there was no significant difference. The posi-tive rate of βhCG mRNA expression was 54% in 24 cases of benign renal tissues, including 3 casesout of 6 polycystic kidneys, 7 cases out of 13 renal atrophies, 2 cases out of 2 oncocytomas and 1case out of 2 pyonephrotic kidneys. β7 was most frequently transcribed subtype gene independent onthe histology. These findings suggested βhCG gene transcription is not only involved in RCC but al-so in benign renal diseases.

    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.

    Abstract Previous studies have warned against the promoting effects of cigarette smoking on benign prostatic hyperplasia (BPH). In contrast, some have argued that smoking confers a protective effect regarding BPH, while others have observed an aggravated effect. Thus, we performed this meta-analysis to determine whether cigarette use is associated with BPH risk. To identify articles from observational studies of relevance, a search was performed concurrent to March 21, 2016, on PubMed, Web of Science, Cochrane, EBSCO, and EMBASE databases. Random-effect model, according to the heterogeneity, was calculated to reveal the relative risks (RRs) and corresponding 95% confidence intervals (CIs). Eight articles were included in this meta-analysis, representing data for 44,100 subjects, of which 5221 (11.8%) had BPH as defined according to the criteria. Seven reports are concerned with analysis between nonsmokers and ex-smokers, in which no significant difference was observed (RR = 0.99, 95% CI 0.94–1.05). Another meta-analysis of 7 studies indicated an observable trend, but without significant difference between groups of nonsmokers and current smokers (RR = 1.17, 95% CI 0.98–1.41). Between groups of heavy (6 articles; RR = 1.02, 95% CI 0.84–1.24) and light smokers (5 articles; RR = 0.90, 95% CI 0.71–1.15), again no significant difference appears. Finally, we combined individuals as never-smokers and ever-smokers and still found no significant difference between the 2 groups of patients (RR = 1.03, 95% CI 0.92–1.15). Sensitivity analysis was displayed and confirmed the stability of the present results. Combined evidence from observational studies shows no significant association between cigarette smoking and BPH risk, either for ex-smokers or for current smokers. The trend of elevated BPH risk from smoking was observed only in current smokers compared with nonsmokers, while marginal significance was observed in comparing ever-smokers with

  19. 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.)

    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.

    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.

    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 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.

    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

  6. 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

  7. 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.

    Full Text Available Benign metastasizing leiomyoma (BML is a rare disease that usually occurs in women of reproductive age. They typically have history of uterine leiomyoma treated with hysterectomy. BML can metastasize to distant organs, with the lung being the most common organ. We report two patients who presented with benign metastasizing leiomyoma to the lung. Our first case was a fifty-two-year-old female who presented with multiple lung masses, with a past medical history of uterine leiomyoma who underwent hysterectomy 17 years ago. A CT-guided biopsy showed benign appearing spindle cells and pathology confirmed her diagnosis with additional positive estrogen/progesterone receptor stains. Our second case was a fifty-six-year-old female who presented with multiple cavitary pulmonary nodules. She subsequently underwent a video-assisted thoracoscopic surgery (VATS with wedge resection of one of the nodules. Pathology confirmed the diagnosis based on morphology and immunohistochemical staining strongly positive for estrogen/progesterone receptors. Benign metastasizing leiomyoma is a rare condition which may affect women of reproductive age. This should be considered in the differential in patients who present with multiple pulmonary nodules, especially with a history of uterine leiomyoma. Additional stains, such as estrogen/progesterone receptors, may need to be done to confirm the diagnosis.

    AIM: To investigate the occurrence of chromosome 3, 7,8, 9, and 17 aneuploidies, TP53 gene deletion and p53 protein expression in chronic gastritis, atrophic gastritis and gastric ulcer, and their association with H pylori infection.METHODS: Gastric biopsies from normal mucosa (NM,n = 10), chronic gastritis (CG,n =38), atrophic gastritis (CAG, n=13) and gastric ulcer (GU, n = 21) were studied using fluorescence in situ hybridization (FISH) and immunohistochemical assay. A modified Giemsa staining technique and PCR were used to detect H pylori. An association of the gastric pathologies and aneuploidies with H pylori infection was assessed.RESULTS: Aneuploidies were increasingly found from CG (21%) to CAG (31%) and to GU (62%), involving mainly monosomy and trisomy 7, trisomies 7 and 8, and trisornies 7, 8 and 17, respectively. A significant association was found between H pylori infection and aneuploidies in CAG (P= 0.0143) and GU (P= 0.0498). No TP53 deletion was found in these gastric lesions, but p53-positive immunoreactivity was detected in 45% (5/11) and 12% (2/17) of CG and GU cases, respectively. However, there was no significant association between p53 expression and H pylori infection.CONCLUSION: The occurrence of aneuploidies in benign lesions evidences chromosomal instability in early stages of gastric carcinogenesis associated with H pylori infection, which may confer proliferative advantage. The increase of p53 protein expression in CG and GU may be due to overproduction of the wild-type protein related to an inflammatory response in mucosa.

    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.)

    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.

  16. 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.

    This work aims to estimate the prevalence of Helicobacter pylori ureA gene and evaluate cagA gene-positive strains in both patients of laryngeal squamous cell carcinoma (LSCC) and those with benign laryngeal polyps. This study included 49 patients confirmed pathologically to have LSCC and 15 patients with benign laryngeal polyps over a period from June 2013 to March 2015. Samples of laryngeal tissue were collected during direct laryngoscope under general anesthesia to be pathologically evaluated followed by analysis for H. pylori detection. Each laryngeal tissue sample was divided into three parts; one for bacteriological examination, the second for pathological examination and the third for PCR to detect both ureA and cagA genes. Out of 49 LSCC samples, 31 (64.6 %) was positive for ureA by PCR. Out of them, 29 samples (93.5 %) were cagA positive. Only three cases (20 %) of the benign laryngeal polyp were ureA positive by PCR and one of them was cagA positive by PCR. By the bacteriological culture, only eight samples (25.8 %) gave growth. All of them were ureA positive and only seven of them were cagA positive. There was a significant association between presence of H. pylori and LSCC as compared to benign laryngeal polyp which may contribute in the pathogenesis of laryngeal carcinoma. These results should be confirmed by further studies over larger number of cases.

    A benign cementoblastoma, which is another name for a true cementoma, is a rare neoplasm that develops from odontogenic ectomesenchyme. It is characterized by a mineralized mass attached to the apex of the root produced by neoplastic cementoblasts. More than 75% of cases arise in the mandible, with 90% of them manifesting in the molar and premolar regions. This neoplasm occurs most commonly in children and young adults, with males being affected slightly more than females. Radiographically, the tumor is observed as a well-defined radiopaque mass that is fused to a tooth root and is surrounded by a radiolucent rim. The treatment of benign cementoblastoma consists of removal of the lesion and extraction of the affected tooth. This report presents an unusual case of benign cementoblastoma in a 31-year-old female, presenting as a densely mineralized mass seen at the apex of the impacted right mandibular canine tooth on radiographs.

    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.

    Kaffes, Arthur J

    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

    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.

  11. 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.

    Benign tumors of the mandible are uncommon lesions. That were classified into odontogenic tumors and nonodontogenic tumors. Author reviewed the radiological evaluation and pathological microscopic finding from 33 benign tumors of the mandible that were confirmed by the biopsy during last 10 years in Dental Clinics, Ewha Womans University Hospital and Seoul National University Dental Hospital. Following results were obtained; 1. Benign tumors of the mandible were classified into odontogenic (66.7%) and non-odontogenic tumors (33.3%). 2. The range of the age distribution was between 6 years and 67 years old. The commonest age group was the second decade (39.4%). 3. There was no difference to sex distribution. 4. The most frequent location was the body of the mandible (42.4%). 5. Radiographic findings were relatively characteristic in odontogenic tumors rather than non-odontogenic tumors. 1) Radiolucent cystic lesions-ameloblastoma, odontogenic myxoma, odontogenic fibtoma, aneurysmal bone cyst and neurofibroma. 2) Radiopaque mass lesions-odontoma, cementoma and osteoma. 3) Mixed patterns-ossifying fibroma, cementifying fibroma, calcifying odontogenic epithelial tumor and hemangioma. It was concluded that the radiographic examination was of value to diagnose the benign tumors of the mandible in symptomless patients.

    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

    KIT (CD117, c-kit) is a receptor tyrosine kinase involved in the tumorigenesis of several neoplasms. KIT is expressed by the secretory cells of normal sweat glands. We studied the KIT expression and KIT mutational status in various benign and malignant tumors of eccrine and apocrine glands. We included a total of 108 cases comprising 10 benign and 6 malignant sweat gland tumors, and KIT expression was immunohistochemically detected (positive rate): 10 syringomas (0%), 8 poromas (25%), 20 mixed tumors (40%), 21 spiradenomas (43%), 1 cylindroma (0%), 5 hidradenomas (40%), 7 syringocystadenoma papilliferum cases (0%), 1 papillary hidradenoma (100%), 2 tubulopapillary hidradenomas (50%), 8 hidrocystomas (29%), 2 adenoid cystic carcinomas (100%), 5 porocarcinomas (20%), 6 apocrine carcinomas (33%), 10 extramammary Paget diseases (30%), 1 spiradenocarcinoma (100%), and 1 syringocystadenocarcinoma papilliferum (0%). Most KIT-positive cells were luminal cells, arising from glandular structures. We performed polymerase chain reaction-single-strand conformation polymorphism for detecting KIT mutational status. All cases showed no mutations at hot spots for KIT (exons 9, 11, 13, and 17). KIT mutation does not seem to be mechanism for KIT expression, but the expression may be from native sweat glands.

    Laparoscopic treatment of benign esophageal conditions is technically complex with several inherent limitations. Robotic-assisted surgery provides technical improvement and helps to overcome some of these limitations. We therefore report a single surgeon's experience in management of benign esophageal diseases by robotic-assisted surgery. Over a period of 8 consecutive years, a retrospective chart review was performed of 105 patients who underwent robotic-assisted surgery for benign esophageal diseases by a single surgeon. Demographic data and outcome measures were studied. The robotic-assisted procedures included 85 Nissen fundoplications with and without mesh repair, 12 Heller myotomies and eight para-esophageal hernia repairs. The mean total operating time was lowest for the Nissen group (94 min) and highest for the para-esophageal group (183 min). Operating time decreased from a mean of 105 min in the first 20 cases to 84 min in the last 20 cases for the Nissen group (P = 0.014). The mean length of stay was 1.3, 1.6, 1.5 and 4.8 days for the groups, respectively. Persistent symptoms of dysphagia/reflux/dysphonia requiring further investigation were seen in nine (8 %) of these patients. Two of these patients required repeat Nissen fundoplication in the mesh group. Our complication rate, total operating time and length of stay for robotic-assisted benign esophageal surgery are comparable to those reported in the literature. When performed by an experienced surgeon, robotic-assisted surgery is safe and effective in the management of benign esophageal diseases.

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

    Lamborg, C. H.; Buesseler, K. O.; Lam, P. J.

    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.

    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.

    Full Text Available Background: Phyllodes tumors are group of biphasic fibroepithelial tumors of the breast of varying malignant potential, ranging from benign tumors to fully malignant sarcomas. According to the Egyptian National Cancer Institute, female malignant cases showed appreciable increase in the recent time period for breast cancer with the malignant phyllodes tumors representing 0.41% of cases in the year 2003-2004. Aims: This is an immunohistochemical study to compare CD10 expression in benign, borderline, and malignant phyllodes tumors, in order to highlight its diagnostic and prognostic values. Materials and Methods: This study conducted 34 Egyptian female cases of phyllodes tumors of different grades to be studied histologically and immunohistochemically using antibodies against CD10. Statistical Analysis: The Chi-square test was used to determine differences in CD10 expression between benign, borderline, and malignant tumors. One-way ANOVA test was used to determine whether the difference was significant. Significance was established at P<0.05. Results: In the 24 cases of benign phyllodes tumors, only four cases (16.7% showed positive CD10 reactivity. Three cases (60% out of five borderline phyllodes tumors showed positive CD10 reactivity, while four (80% out of five cases of malignant phyllodes tumors showed positive CD10 staining. Conclusion: From these highly significant results, we believe that there is a strong correlation between CD10 expression and tumor grade, which could be an important observation that may have both diagnostic and prognostic implications as well as promising potential target for development of novel therapies.

    The first histologically confirmed case of a classic chordoma arising in a precursor benign notochordal lesion is presented and the differential diagnosis between benign and malignant notochordal lesions is discussed. A 57-year-old man presented with a classic chordoma in the coccyx. The resected specimen demonstrated a small intraosseous benign notochordal lesion in the coccyx, which was adjacent to the classic chordoma. Also seen were two separate, similar benign lesions in the sacrum. The classic chordoma consisted of multiple lobules that were separated by thin fibrous septa and that showed cords or strands of atypical physaliphorous cells set within an abundant myxoid matrix. In contrast, the benign lesions consisted of intraosseous sheets of bland physaliphorous cells without any extracellular matrix. The affected bone trabeculae showed sclerotic reactions. It was concluded that benign and malignant notochordal lesions can be distinguished microscopically. (orig.)

    Full Text Available Cervical meningoceles are rare spinal dysraphism, accounting for approximately 7% of all cystic spinal dysraphism. In spite of the rarity, the clinical course is most of the times benign. The surgical treatment includes resection of the lesion and untethering, when presented. We present a 14-day-old female child with true meningoceles who underwent to surgical excision and dura-mater repair. Retrospect analysis of the literature concerning true cervical meningocele is performed. By reporting this illustrative case, we focus on its classification and its differentiation from other types of cervical spinal dysraphism, such as myelocystocele and myelomeningocele. Although its course is benign, it is mandatory a continuum follow up with periodic magnetic resonance imaging of spinal cord, since late neurological deterioration has been described.

    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.

    Benign prostatic hyperplasia (BPH), also known as benign prostatic hypertrophy, is a nonmalignant adenomatous overgrowth of the periurethral prostate gland commonly seen in aging men. Historically, it has been assumed that the pathophysiology of lower urinary tract symptoms in men is the result of bladder outlet obstruction associated with prostate enlargement. Symptoms such as urinary hesitancy, incomplete bladder emptying, dribbling or prolonged urination, nocturia, urinary urgency, and/or urge incontinence are common. Understanding the differential diagnosis and ordering appropriate laboratory tests are essential in accurately identifying a BPH diagnosis. Management can be broken down into medical or pharmacological and surgical therapies. This article aims to provide an overview of BPH and its management in older adults. PMID:27535076

    Bone marrow oedema is associated with a wide variety of pathological processes including both benign and malignant bone tumours. This imaging finding in relation to intraosseous tumours can aid in providing a more focused differential diagnosis. In this review, we will discuss the MR imaging of bone marrow oedema surrounding intraosseous neoplasms. The different pulse sequences used in differentiating underlying tumour from surrounding oedema are discussed along with the role of dynamic contrast enhanced MRI. Benign lesions commonly associated with bone marrow oedema include osteoid osteoma, osteoblastoma, chondroblastoma and Langerhan's cell histiocytosis. Metastases and malignant primary bone tumours such as osteosarcoma, Ewing's sarcoma and chondrosarcoma may also be surrounded by bone marrow oedema. The imaging findings of these conditions are reviewed and illustrated. Finally, the importance of bone marrow oedema in assessment of post chemotherapeutic response is addressed.

    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.

    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 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.

    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.

    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

    Full Text Available Surgical resection is usually prefered for the treatment of benign nodular goiter. But the extention of thyroidectomy in the surgical management of benign nodular goiter still remains controversial. Seventytwo patients underwent thyroid surgery between April 2002- July2007 in Kızıltepe State Hospital Otorhinolaryngology Service. Of the patients 63 were women (%87.5, 9 were man (%12.5. The range of age was between 15-62 years and mean age was 36,5. Thirtynine patients had unilateral total lobectomy+ istmusectomy (%54.2, 11 patients had unilateral lobectomy+ isthmusectomy+contralateral subtotal lobectomy (Dunhill Procedure (%15.3, 20 patients had nearly total thyroidectomy (%27.8, 2 patients had total thyroidectomy (% 2.7. Three patients had seroma (%4.1, 2 patients had hemorrhage requiring operative hemostasis (%2.7, 1 patient had suture reaction(%1.3. Patients have not had permanent or temporary nervus laryngeus recurrens injury, hypoparathyroidism and infection.As a result more extent surgical resections must be preferred by the surgeon for the treatment of benign nodular goiter. The preferable surgical treatment of solitary nodules is lobectomy+isthmusectomy. The multinodular goiter must be treated with unilateral lobectomy+ isthmusectomy+contralateral subtotal lobectomy (Dunhill procedure when the remnant thyroid tissue is normal; otherwise nearly total or total thyroidectomy is preferable.

    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.

    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.

    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.

    Pneumopericardium is a rare radiologic finding and is most commonly associated with esophageal ulceration or trauma. Benign ulcers of the distal esophagus are the most frequent source of non-traumatic perforation into the pericardial sac. Other etiologies include fistula formation from diseased subdiaphragmatic hollow viscera or subphrenic abscess, recent cardiac surgery, an extension of pneumomediastinum into the pericardium sac, and primary septic pericarditis from gasforming organisms. Pneumopericardium caused by the penetration of a benign gastric ulcer is a recognized but rare phenomenon. Intrathoracic gastric perforations are more commonly associated with pneumomediastium. Risk factors associated with an increased risk of penetration of gastric ulcers into the pericardium include the presence of a giant ulcer in the gastric fundus, an ulcer within a hiatus hernia, a history of hiatus hernia repair, concurrent use of non-steroidal anti-inflammatory drugs and the Zollinger-Ellison syndrome. Scar tissue formation at the site of previous hiatal surgery may result in the adherence of the gastric fundus or lower esophagus to the pericardium and produce a pathway for benign ulcers to erode into the pericardium.

    In vitro DNA amplification followed by oligonucleotide mismatch hybridization was used to study the frequency of HRAS mutations in the benign self-regressing skin tumors keratoacanthomas and in squamous cell carcinomas. The authors used freshly obtained keratoacanthomas as well as Formalin-fixed paraffin-embedded tissues from both types of tumors. DNA from 50 samples of each tumor type was analyzed for activating mutations involving codons 12 and 61. A relatively high percentage (30%) of HRAS mutations was found in the keratoacanthomas compared with 13% in the squamous cell carcinomas. The most frequent mutation identified is the A{center dot}T-to-T{center dot}A transversion in the second position of codon 61. The present findings demonstrate the involvement of the HRAS oncogene in human benign tumors. Moreover, they indicate that an activated HRAS oncogene is not sufficient to maintain a neoplastic phenotype and argue against a role of HRAS in the progression of skin tumorigenesis.

    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.

    The aim of this study was to determine the expression of matrix metalloproteinase 2 (MMP-2) and tissue inhibitors of matrix metalloproteinase 2 (TIMP-2) and the MMP-2/TIMP-2 expression ratio in salivary gland tumours (SGTs). Forty-three FFPE SGTs were prepared for antibody processing to MMP-2 and TIMP-2. Two investigators utilizing Sinicrope's method scored the uptake of immuno-stains. Cytoplasmic staining was considered as positive. Data was analysed using SPSS version 20. The significance level was set at p benign SGTs, the mean score for MMP-2 was not significantly lower than that of TIMP-2 (p = 0.37). However, the mean scores for MMP-2 stain intensity and proportion were significantly higher in malignant than benign SGTs (p = 0.01 and p = 0.02 respectively). There was no significant difference in the mean MMP-2/TIMP-2 expression ratio of the malignant SGTs according to histological grade and histogenesis (p = 0.4 and p = 0.19 respectively). The MMP-2/TIMP-2 expression ratio has a higher prognostic value than the separate expressions of MMP-2 and TIMP-2.

    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.

    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

    Objective Signal transducer and activator of transcription 3 (Stat3) and survivin have been shown to exert oncogenic effects in various human neoplasms. The purpose of this study was to evaluate the expression of the tyrosine phosphorylated (active) Stat3 and survivin in various benign and malignant salivary gland tumors (SGTs). Study design Eighty-six SGTs (65 malignant and 21 benign tumors of various histopathologic subtypes) were immunohistochemically stained with anti-survivin or anti-phosphorylated tyrosine-705 (p-tyr) Stat3 antibodies. Immunohistochemical reactivity was graded in a semi-quantitative manner; a combined score of immunohistochemical positivity (0–6) was calculated for each tumor by adding the individual scores for percentage of tumor cells (0–3) and intensity of staining (0–3). Results Survivin was immunohistochemically detected in all studied benign and malignant SGTs; p-tyr Stat3 was also detected in the majority (91%) of SGTs. The average combined scores for survivin and p-tyr Stat3 immunohistochemical expression in the studied malignant SGTs was 4.40 and 3.35, respectively; the corresponding combined scores for survivin and p-tyr Stat3 in the studied benign SGTs were 4.37 and 3.22, respectively. No statistically significant differences (p>0.05) in p-tyr Stat3 or survivin expression were detected between the benign and malignant groups, or among the various examined histopathological subtypes of SGTs. In contrast, normal salivary gland elements in the vicinity of the studied tumors revealed only weak and focal survivin or p-tyr Stat3 immunoreactivity, mainly localized to ductal and mucous cells. Conclusions Our data indicate an almost universal expression of activated Stat3 and survivin in benign and malignant SGTs. Considering the well-established proliferative and anti-apoptotic properties of these molecules and their functional interrelationship, selective targeting techniques against Stat3 and/or survivin may represent promising

    Objective To discuss early therapy scheme for cervical vertigo in mild and moderate head injury. Methods Eighty-four patients suffering from cervical vertigo in mild or moderate head injury were randomly divided into 2 groups: combined therapy group (n=38) and control group (n=46). In the combined therapy group, patients underwent cervical vertebra traction and stellate ganglion block and early physical therapy for cervix as well as medication; in the control group, simple medication was used. The results were analyzed by nonparametric rank sum test Ridit analysis. Results In the combined therapy group, 29 cases were cured, 8 got better, and 1 remained unchanged, average therapy duration 20 d, while in the control group, 26 were healed, 15 changed better, and 5 did not show a sign of recovery, average therapy duration 30 d. The curative effect was significantly different between the 2 groups, and the combined therapy group was better than the control group (P<0.05).
