Venous thromboembolism (VTE) is the leading cause of mortality and morbidity in women following gynecologic surgery. To determine the efficacy of a second-generation low molecular weight heparin (bemiparin) for thromboprophylaxis after benign gynecologic surgery. We performed a single-blind randomized controlled trial including women in the moderate-risk, high-risk and highest-risk groups for developing VTE after benign gynecologic surgery. Participants were randomized at a 1 : 1 ratio into parallel groups to receive either seven daily doses of 3500 IU of subcutaneous bemiparin or to a non-intervention group receiving standard rehydration and advice on ambulation. Participants were followed up for 7 days and 30 days postoperatively for symptomatic VTE, which was confirmed by compression Doppler ultrasound, magnetic resonance imaging, or computed tomographic pulmonary angiography, according to the type of VTE. In total, 387 participants were randomized to the bemiparin group and 387 to the non-intervention group. The incidence of symptomatic VTE (deep vein thrombosis and pulmonary embolism) events was lower (0/377) in participants who received bemiparin than in those who received no pharmacologic intervention (12/380, 3.2%; 95% confidence interval [CI] 0.002-0.6). Logistic regression analysis showed significant associations between VTE and immobility (odds ratio [OR] 7.1; 95% CI 1.3-36.2), varicose veins (OR 16.8; 95% CI 3.1-76.2), and thrombophilia (OR 39.3; 95% CI 1.5-1006.7). There were no major bleeding events or side effects related to the use of bemiparin. Bemiparin was an effective thromboprophylactic agent for preventing venous thrombosis after benign gynecologic surgery. © 2015 International Society on Thrombosis and Haemostasis.

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.

Annual incidence of symptomatic adjacent level disease (ALD) following lumbar fusion surgery ranges from 0.6% to 3.9% per year. Sagittal malalignment may contribute to the development of ALD. To describe the relationship between pelvic incidence-lumbar lordosis (PI-LL) mismatch and the development of symptomatic ALD requiring revision surgery following single-level transforaminal lumbar interbody fusion for degenerative lumbar spondylosis and/or low-grade spondylolisthesis. All patients who underwent a single-level transforaminal lumbar interbody fusion at either L4/5 or L5/S1 between July 2006 and December 2012 were analyzed for pre- and postoperative spinopelvic parameters. Using univariate and logistic regression analysis, we compared the spinopelvic parameters of those patients who required revision surgery against those patients who did not develop symptomatic ALD. We calculated the predictive value of PI-LL mismatch. One hundred fifty-nine patients met the inclusion criteria. The results noted that, for a 1° increase in PI-LL mismatch (preop and postop), the odds of developing ALD requiring surgery increased by 1.3 and 1.4 fold, respectively, which were statistically significant increases. Based on our analysis, a PI-LL mismatch of >11° had a positive predictive value of 75% for the development of symptomatic ALD requiring revision surgery. A high PI-LL mismatch is strongly associated with the development of symptomatic ALD requiring revision lumbar spine surgery. The development of ALD may represent a global disease process as opposed to a focal condition. Spine surgeons may wish to consider assessment of spinopelvic parameters in the evaluation of degenerative lumbar spine pathology. Copyright © 2017 by the Congress of Neurological Surgeons

Fowler, Sara; Reader, Al; Beck, Mike

2015-05-01

The purpose of this retrospective study was to determine the incidence of missed inferior alveolar nerve (IAN) blocks by using a 1- or 2-cartridge volume of 2% lidocaine with 1:100,000 epinephrine in vital asymptomatic teeth and in emergency patients with symptomatic irreversible pulpitis. As part of 37 studies, 3169 subjects/patients were evaluated for missed IAN blocks. The study included 2450 asymptomatic subjects and 719 emergency patients presenting with symptomatic irreversible pulpitis. Each subject or patient received either a 1- or 2-cartridge volume of 2% lidocaine with 1:100,000 epinephrine. A missed block was defined as no lip numbness at 15-20 minutes after the IAN block. The effect of anesthetic volume on the incidence of missed blocks was assessed by using mixed models logistic regression with individual studies as a random effect. The incidence of missed blocks for asymptomatic subjects was 6.3% for the 1-cartridge volume and 3.8% for the 2-cartridge volume. For patients presenting with irreversible pulpitis, the incidence of missed blocks was 7.7% for the 1-cartridge volume and 2.3% for the 2-cartridge volume. In both asymptomatic subjects and patients with irreversible pulpitis, the 2-cartridge volume was significantly (P = .0395) better than the 1-cartridge volume. There were no significant effects for pulpal diagnosis (P = .7523) or the pulpal diagnosis and anesthetic volume interaction (P = .3973). Concerning missed IAN blocks, we concluded that administration of a 2-cartridge volume was significantly better (P = .0395) than a 1-cartridge volume in both asymptomatic subjects and emergency patients presenting with irreversible pulpitis.

Reddy, Sahadev T.; Biederman, Robert W. W.

2016-01-01

Cardiac lipomatous hypertrophy is a rare benign condition that usually involves the interatrial septum. Due to its benign nature it rarely requires intervention. Its presence outside the interatrial septum is reported infrequently. We present a case of lipomatous hypertrophy in the intraventricular septum that was complicated by a severe, symptomatic, and disabling dynamic left ventricular outflow tract obstruction. The symptoms significantly improved following the excision of the mass. In our case transthoracic echocardiogram was used to visualize the mass and measure the severity of the obstruction; Cardiac Magnetic Resonance Imaging was used to characterize the mass and histopathology confirmed the diagnosis.

Benign bronchial stenosis is managed by surgical or bronchoscopic methods. Although surgical approach is definitive, it is technically demanding and is costlier than bronchoscopic treatment. Here, we report the case of a 27-year-old female patient with symptomatic benign bronchial stenosis of the left main bronchus. The stenosis was dilated successfully through a fibreoptic bronchoscope by electrocautery followed by balloon bronchoplasty and application of mitomycin-C. On follow up, there was no evidence of re-stenosis.

Gastric lipomas are rare tumors, accounting for 2%-3% of all benign gastric tumors. They are of submucosal or extremely rare subserosal origin. Although most gastric lipomas are usually detected incidentally, they can cause abdominal pain, dyspeptic disorders, obstruction, invagination, and hemorrhages. Subserosal gastric lipomas are rarely symptomatic. There is no report on treatment of subserosal gastric lipomas in the English literature. We present a case of a 50-year-old male with symptom...

Incidence rate of symptomatic painless thyroiditis presenting with thyrotoxicosis in Denmark as evaluated by consecutive thyroid scintigraphies.

2013-04-01

Painless thyroiditis (PT) is a transient kind of thyrotoxicosis, with lack of uptake on a thyroid scintigraphy in a non-tender thyroid gland, elevated anti-TPO antibodies, no fever, no history of increased iodine intake, and a normal sedimentation rate. The prevalence of PT varies hugely in the literature. To establish the incidence rate of PT in Denmark as well as to describe the phenotype of PT in more detail. Tc-99m pertechnetate scintigraphies were performed over a period of 9.75 years on 6022 consecutive patients (2349 had a thyrotoxic episode), and were divided into high or normal (5528), reduced (300) or lack of uptake (194). Patient records were evaluated: 292 with reduced, and 186 with lack of uptake. As a control measure, 230 consecutive thyrotoxic patients were also analyzed. Based on scintigraphies, 12 patients had PT, 10 with lack of uptake and two with reduced, corresponding to an incidence rate of 0.49/100,000 person years. It was predicted, that only one patient among the newly diagnosed consecutive thyrotoxic cohort had PT. This patient was identified. The prevalence of PT among thyrotoxic patients was 0.51% as evaluated by scintigraphy, and 0.43% among the biochemically thyrotoxic patient cohort. Twenty-five percent had more than one thyrotoxic episode, 75% had at least one subsequent hypothyroid episode, and 33% developed permanent hypothyroidism. PT presenting with symptomatic thyrotoxicosis is an extremely rare disease in Denmark. Symptomatic PT presents most often with no uptake on a Tc-99m pertechnetate scintigraphy. Clinical follow-up is essential.

Benign notochordal lesions of the axial skeleton: a review and current appraisal

Kyriakos, Michael

2011-01-01

At the 1996 meeting of the International Skeletal Society, an idea was put forth that there existed symptomatic lesions of the axial skeleton, morphologically different from chordoma, that were consistent with benign notochordal remnants (rests). A review of the embryological basis for this concept is made, along with an analysis of these lesions, termed giant notochordal rests or benign notochordal cell tumors, that have been reported in the intervening 15 years, with a commentary on their relationship, if any, to chordoma.

Distal pancreatectomy is the standard curative treatment for symptomatic benign, premalignant, and malignant disease of the pancreatic body and tail. The most obvious benefits of a laparoscopic approach to distal pancreatectomy include earlier recovery and shorter hospital stay. Spleen-preserving distal pancreatectomy should be attempted in case of benign disease. Spleen preservation can be achieved preferably by preserving the splenic vessels (Kimura technique), but also by resecting the splenic vessels and maintaining vascularity through the short gastric vessels and left gastroepiploic artery (Warshaw technique). Several studies have suggested a higher rate of spleen preservation with laparoscopy. The radical antegrade modular pancreatosplenectomy has become mainstay for treating pancreatic cancer and can be performed laparoscopically as well. Evidence on the feasibility and safety of laparoscopic distal pancreatectomy for cancer is scarce. Despite the obvious advantages of laparoscopic surgery, postoperative morbidity remains relatively high, mainly because of the high incidence of pancreatic fistula. For decades, surgeons have tried to prevent these fistulas but to date no strategy has been confirmed to be effective in 2 consecutive randomized studies. Pragmatic multicenter studies focusing on technical aspects of laparoscopic distal pancreatectomy are lacking and should be encouraged. PMID:26240565

Full Text Available BACKGROUND AND OBJECTIVES The breast is the essential symbol of womanhood to society and to the woman herself. Subjected every month to the onslaught of ovarian, adrenal, pituitary and thyroid hormones in tandem with the uterus, the very histological architecture of the breast changes sequentially. With the recent importance given to early diagnosis of cancer of the breast and its early detection by both the patient and her physician, more benign conditions are likely to be detected than earlier. The objective of our review is to find out the incidence of benign breast lump above 40 years of age in females attending our hospital. METHODS AND MATERIALS 130 patients presenting to the outpatient department of KAPV Medical College with breast lump were included in this comprehensive study. A detailed history regarding the duration and nature of the complaints, family history pertaining to breast or ovarian cancers, risk factors such as oral contraceptive use, parity, lactation, etc. was elicited. A thorough clinical examination was performed. RESULTS Of 24 cases of fibroadenoma, all were operated upon by excision. Of 38 patients with fibroadenosis, 30 patients managed conservatively and surgery for 8 patients where the diagnosis was doubtful. Abscesses were incised and drained under antibiotic cover for 3 patients. 8 cases of breast cyst were managed by aspiration. TB mastitis was confirmed by excisional biopsy and followed up by antituberculous therapy with regular follow up after 6 months. Healed lesions were found to be associated with improved general condition of the patients. Lipoma and sebaceous cyst were managed by excision biopsy. CONCLUSION Benign breast diseases were found to be common in woman above 40 years old in contrast to normal teaching, which says they are common in younger age groups. Fibroadenosis was the commonest benign disease closely followed by fibroadenoma. Fibroadenosis was mostly managed conservatively. Excision biopsy

The use of self-expandable metallic stents (SEMS) is an established palliative treatment for malignant stenosis in the gastrointestinal tract; therefore, its application to benign stenosis is expected to be beneficial because of the more gradual and sustained dilatation in the stenotic portion. We aimed in this prospective observational study to evaluate the efficacy and safety of temporary SEMS placement in benign pyloric stenosis. Twenty-two patients with benign stenosis of the prepylorus, pylorus, and duodenal bulb were enrolled and underwent SEMS placement. We assessed symptom improvement, defined as an increase of at least 1 degree in the gastric-outlet-obstruction scoring system after stent insertion. No major complications were observed during the procedures. After stent placement, early symptom improvement was achieved in 18 of 22 patients (81.8%). During the follow-up period (mean 10.2 months), the stents remained in place successfully for 6 to 8 weeks in seven patients (31.8%). Among the 15 patients (62.5%) with stent migration, seven (46.6%) showed continued symptomatic improvement without recurrence of obstructive symptoms. Despite the symptomatic improvement, temporary SEMS placement is premature as an effective therapeutic tool for benign pyloric stenosis unless a novel stent is developed to prevent migration.

Previous small studies have shown either no difference or a lower risk of symptomatic gallstone disease in vegetarians than in non-vegetarians. This study examined the incidence of symptomatic gallstone disease in a cohort of British vegetarians and non-vegetarians, and investigated the associations between nutrient intake and risk of symptomatic gallstone disease. The data were analysed from 49 652 adults enroled in the European Prospective Investigation into Cancer and Nutrition (EPIC)-Oxford study, one-third of whom were vegetarian. The linked databases of hospital records were used to identify incident cases. Risk by diet group was estimated using Cox proportional hazards models. Further analysis quantified risk by intakes of selected macronutrients. There were 1182 cases of symptomatic gallstone disease during 687 822 person-years of follow-up (mean=13.85 years). There was a large significant association between increasing body mass index (BMI) and risk of developing symptomatic gallstone disease (overall trend Pvegetarians had a moderately increased risk compared with non-vegetarians (HR: 1.22; 95% CI: 1.06-1.41; P=0.006). Although starch consumption was positively associated with gallstones risk (P=0.002 for trend), it did not explain the increased risk in vegetarians. There is a highly significant association of increased BMI with risk of symptomatic gallstone disease. After adjusting for BMI, there is a small but statistically significant positive association between vegetarian diet and symptomatic gallstone disease.

Catheter-related central vein thrombosis (CRVT) is a severe complication of home parenteral nutrition (HPN) that may be clinically manifest or subclinical. The aims of the study were to prospectively investigate the incidence of CRVT in patients on HPN with benign disease and determine the influence of different variables on this complication. A prospective, multicentre, observational study in the Home Artificial Nutrition-Chronic Intestinal Failure ESPEN group was performed. Patients with benign disease starting HPN or already on HPN after the insertion of a new catheter, were recruited and followed up with Color Doppler Duplex Sonography (CDDS) evaluations at baseline, 1 week, 3, 6 and 12 months after catheter insertion. Fisher's exact test was used to calculate the association of different variables (related to the patient, type of catheter, vascular access, insertion method, catheter care and anticoagulant treatment) with CRVT events. Sixty-two patients (31 males, 31 females) aged 50 ± 19 (19-83) years were included and followed for a median 363 days, with an Inter Quartile Range of 180-365 days, and a total of 16,186 catheter-days. Six patients had previous CRVT and 16 had history of thromboembolic disease (pulmonary and mesenteric). Forty one patients were receiving anticoagulant treatment. Fifty two patients had tunneled catheters and 10 implanted ports. Two patients had symptomatic thrombosis at 3 and 12 months of follow-up (2 and 3 weeks after normal routine CDDS evaluation). The incidence of CRVT was 0.045/catheter/year. CRVT was not significantly associated with any of the variables analyzed. The incidence of CRVT in patients on HPN for benign disease followed by CDDS is low in the first year of catheterization. We did not observe any case of asymptomatic CRVT. Based on our data, CDDS seems to have low effectiveness as a screening tool for CRVT in asymptomatic patients on HPN with benign disease. Copyright © 2015 Elsevier Ltd and European Society for

The purpose of this study was to identify the incidence of symptoms consistent with athletic pubalgia (AP) in athletes requiring surgical treatment for femoroacetabular impingement (FAI) and the frequency of surgical treatment of both AP and FAI in this group of patients. Thirty-eight consecutive professional athletes, with a mean age of 31 years, underwent arthroscopic surgery for symptomatic FAI that limited their ability to play competitively. In all cases a cam and/or focal rim osteoplasty with labral refixation or debridement was performed. In 1 case concomitant intramuscular lengthening of the psoas was performed. Retrospective data regarding prior AP surgery and return to play were collected. Thirty-two percent of patients had previously undergone AP surgery, and 1 patient underwent AP surgery concomitantly with surgical treatment of FAI. No patient returned to his previous level of competition after isolated AP surgery. Thirty-nine percent had AP symptoms that resolved with FAI surgery alone. Of the 38 patients, 36 returned to their previous level of play; all 12 patients with combined AP and FAI surgery returned to professional competition. The mean duration before return to play was 5.9 months (range, 3 to 9 months) after arthroscopic surgery. There is a high incidence of symptoms of AP in professional athletes with FAI of the hip. This study draws attention to the overlap of these 2 diagnoses and highlights the importance of exercising caution in diagnosing AP in a patient with FAI.

Breast cancer is the most common female malignancy worldwide. Pakistan has the highest incidence rate of breast cancer than any other Asian population. The purpose of the study was to evaluate the worth of sono-mammography in diagnosis of symptomatic breast diseases by comparing it with mammogram. Methods: In this cross-sectional validation study, 45 subjects with mean age of 45+-12.07 were included. Majority of the patients presented with complaint of breast lump. After complete history and clinical examination, all the patients had high resolution ultrasound of bilateral breasts and axilla followed by bilateral mammography. Histopathology was taken as gold standard in this study. The exclusion criteria were pregnancy and patients having direct clinical signs of breast malignancy. Results: Based on histopathology, out of 45 patients with breast symptoms, 12 patients had benign lesions, whereas 32 patients were diagnosed as the cases of breast cancers. Finally one patient did not have biopsy proven final diagnosis. Sensitivity and specificity of ultrasound were calculated to be 100% and 67% as compared to sensitivity and specificity of 90.6% and 91.7% for that of mammography. Conclusions: Ultrasound is a useful complementary tool to mammography in assessment of symptomatic breast diseases since it helps in characterization and localization of breast lesions seen on mammogram and it is not limited by dense breasts. Also it should be the considered as initial imaging technique for assessment of palpable breast lumps. (author)

The incidence of GER in symptomatic babies varies from 22% to 85%, but literature regarding the incidence of reflux in asymptomatic pre-term infants is lacking. We used radionuclide scintigraphy to evaluate the incidence of GER in symptomatic as well as asymptomatic pre-term neonates and to assess whether symptoms have any relation with positive scintigraphy. We studied 106 pre-term infants (52 symptomatic, 54 asymptomatic) of less than 34 weeks of gestation, who fulfilled the eligibility criteria. Babies were considered symptomatic in the presence of vomiting, regurgitation, apnea, de-saturations, unexplained bradycardia and recurrent lung collapses. Radionuclide scintigraphy was conducted at post-conceptional age of 32-34 weeks when they were clinically stable for 72 h. Feeding was avoided for 2 h preceding the study. {sup 99m}Tc sulphur colloid was administered in a dose of 1.85 MBq (0.05 mCi) in 1 ml, followed by milk (full feed) through an orogastric tube, prior to imaging under a gamma camera. Reflux was graded as low or high, and reflux episodes during the study were counted. The incidence of GER in the symptomatic group was 71.2% and in asymptomatic babies 61.1% (p=0.275). High-grade reflux was more common (71.4%) than low-grade (28.6%) in both groups (p=0.449). Mean number of reflux episodes in 20 min was 4.4{+-}2.4 in symptomatic babies and 4.9 {+-}2.2 in asymptomatic babies (p=0.321). Babies with positive scintigraphy were similar in birth weight, gestation, time to achieve full feeds, weight and age at discharge to those with negative scintigraphy. GER is common in pre-term infants of less than 34 weeks gestation. The incidence of positive scintigraphy and grade of reflux is not significantly different in symptomatic vs. asymptomatic babies. Though radionuclide scintigraphy is a simple, quick and non-invasive investigation in

Urodynamic implications of benign prostatic hyperplasia

DEFF Research Database (Denmark)

Jensen, K M; Andersen, J T

1990-01-01

By the age of 60, about 70% of men have developed benign prostatic hyperplasia (BPH), and 85%-95% of these have symptomatic dysfunction of the lower urinary tract, 10%-20% undergoing prostatectomy. Although transurethral resection of the prostate is generally considered to be a safe and effective...... instability has no bearing on the postoperative result. Measurement of urinary flow, in contrast, is of predictive value in BPH, patients in whom the maximum urinary flow before surgery is more than 15 ml/s having significantly worse results of surgery than those with a maximum urinary flow of less than 15 ml...

Uterine fibroids, the most common benign tumor in women of childbearing age, may cause symptoms including pelvic pain, menorrhagia, dysmenorrhea, pressure, urinary symptoms, and infertility. Various approaches are available to treat symptomatic uterine fibroids. Magnetic Resonance-guided Focused Ultrasound Surgery (MRgFUS) represents a recently introduced noninvasive safe and effective technique that can be performed without general anesthesia, in an outpatient setting. We review the principles of MRgFUS, describing patient selection criteria for the treatments performed at our center and we present a series of five selected patients with symptomatic uterine fibroids treated with this not yet widely known technique, showing its efficacy in symptom improvement and fibroid volume reduction.

Renal oncocytomas are benign tumours, often asymptomatic, and picked incidentally on radiological imaging. We present a case report of a symptomatic giant renal oncocytoma in a 61-year old man having lower back\\/right flank pain. A large right renal mass was identified on abdominal CT scan. Radiological features were not sufficient to differentiate this lesion from renal cancer. Right radical nephrectomy was performed. Typical features of oncocytoma, without evidence of malignancy, were seen on histological examination of the specimen. In this report, we discuss literature review of radiological, genetic, and pathological characteristics of renal oncocytoma.

Tracheal stenosis is a potentially life-threatening condition. Tracheostomy and endotracheal intubation remain the commonest causes of benign stenosis, despite improvements in design and management of tubes. Post-tracheostomy stenosis is more frequently encountered due to earlier performance of tracheostomy in the intensive care units, while the incidence of post-intubation stenosis has decreased with application of high-volume, low-pressure cuffs. In symptomatic benign tracheal stenosis the gold standard is surgical reconstruction (often after interventional bronchoscopy). Stenting is reserved for symptomatic tracheal narrowing deemed inoperable, due to local or general reasons: long strictures, inflammation, poor respiratory, cardiac or neurological status. When stenting is decided, silicone stent insertion is considered the treatment of choice in the presence of inflammation and/or when removal is desirable. We inserted tracheal silicone stents (Dumon) under general anaesthesia through rigid bronchoscopy in two patients with benign post-tracheostomy stenosis: a 39-year old woman with failed initial operation, and continuous relapses with proliferation after multiple bronchscopic interventions, and a 20-year old man in a poor neurological status, with a long tracheal stricture involving the subglottic larynx (lower posterior part), and inflamed tracheostomy site tissues (positive for methicillin resistant staphylococcus aureus). The airway was immediately re-establish, without complications. At 15- and 10-month follow-up (respectively) there was no stent migration, luminal patency was maintained without: adjacent structure erosion, secretion adherence inside the stents, granulation at the ends. Tracheostomy tissue inflammation was resolved (2(nd) patient), new infection was not noted. The patients maintain good respiratory function and will be evaluated for scheduled stent removal. Silicone stents are removable, resistant to microbial colonization and are

Indications for surgical resection of benign pancreatic tumors

International Nuclear Information System (INIS)

Isenmann, R.; Henne-Bruns, D.

2008-01-01

Benign pancreatic tumors should undergo surgical resection when they are symptomatic or - in the case of incidental discovery - bear malignant potential. This is the case for the majority of benign pancreatic tumors, especially for intraductal papillary mucinous neoplasms or mucinous cystic adenomas. In addition, resection is indicated for all tumors where preoperative diagnostic fails to provide an exact classification. Several different operative techniques are available. The treatment of choice depends on the localization of the tumor, its size and on whether there is evidence of malignant transformation. Partial duodenopancreatectomy is the oncological treatment of choice for tumors of the pancreatic head whereas for tumors of the pancreatic tail a left-sided pancreatectomy is appropriate. Middle pancreatectomy or duodenum-preserving resection of the pancreatic head is not a radical oncologic procedure. They should only be performed in cases of tumors without malignant potential.

Focal hot nodules on iodine thyroid images are associated with an exceedingly low incidence of malignancy. Most previously reported hot carcinomas represent the coexistence of small malignancies in or adjacent to a benign hot lesion. Described here is a 3-cm papillary carcinoma that fulfilled the criteria for benignancy on Tc-99m and I-123 imaging. Coincidental carcinoma within a benign lesion was excluded by detailed scintigraphic-pathologic correlation of the tumor. The implications of this case on the management of the solitary hot nodule are discussed and the literature reviewed.

An association between aggrecan gene variable number of tandem repeats polymorphism (VNTR) and symptomatic lumbar disc herniation (LDH) has been reported in Chinese Han of Northern China, and obesity had previously been suspected of causing severe LDH. However, the interaction between aggrecan VNTR and obesity in symptomatic LDH has not been well studied. To examine the interaction between aggrecan VNTR and obesity in the susceptibility of symptomatic LDH, 259 participants participated in this study and donated a blood sample. The disease group comprised 61 patients already diagnosed with symptomatic LDH. The control group consisted of 198 healthy blood donors without symptoms of LDH who were not diagnosed with LDH. The aggrecan gene VNTR region was analyzed using polymerase chain reaction. The data indicated that between the two groups, participants carrying one or two alleles ≤25 repeats who were non-obese people showed a 1.057-fold increase in risk for symptomatic LDH (p = 0.895, changing the number of repeat alleles to 25 repeats who were obese people showed an 1.061-fold higher risk (p = 0.885, adding obesity to the mix alone did not demonstrably increase the risk of LDH), while participants carrying one or two alleles ≤25 repeats who were obese people showed a 4.667-fold increase in risk for symptomatic LDH (p = 0.0003, adding obesity plus changing the repeat allele number significantly increased the risk of LDH by 4.667). Overall, the findings suggest an underlying interaction between aggrecan VNTR and obesity in symptomatic LDH.

Seizures are believed to be common presenting symptoms in neonates and children with spontaneous intracerebral hemorrhage (ICH). However, few data are available on the epidemiology of acute symptomatic seizures or the risk for later epilepsy. To define the incidence of and explore risk factors for seizures and epilepsy in children with spontaneous ICH. Our a priori hypotheses were that younger age at presentation, cortical involvement of ICH, acute symptomatic seizures after presentation, ICH due to vascular malformation, and elevated intracranial pressure requiring urgent intervention would predict remote symptomatic seizures and epilepsy. Prospective cohort study conducted between March 1, 2007, and January 1, 2012. Three tertiary care pediatric hospitals. Seventy-three pediatric subjects with spontaneous ICH including 20 perinatal (≥37 weeks' gestation to 28 days) and 53 childhood subjects (>28 days to Acute symptomatic seizures (clinically evident and electrographic-only seizures within 7 days), remote symptomatic seizures, and epilepsy. Acute symptomatic seizures occurred in 35 subjects (48%). Acute symptomatic seizures as a presenting symptom of ICH occurred in 12 perinatal (60%) and 19 childhood (36%) subjects (P = .07). Acute symptomatic seizures after presentation occurred in 7 children. Electrographic-only seizures were present in 9 of 32 subjects (28%) with continuous electroencephalogram monitoring. One-year and 2-year remote symptomatic seizure-free survival rates were 82% (95% CI, 68-90) and 67% (95% CI, 46-82), respectively. One-year and 2-year epilepsy-free survival rates were 96% (95% CI, 83-99) and 87% (95% CI, 65-95), respectively. Elevated intracranial pressure requiring acute intervention was a risk factor for seizures after presentation (P = .01; Fisher exact test), remote symptomatic seizures, and epilepsy (P = .03, and P = .04, respectively; log-rank test). Presenting seizures are common in perinatal and childhood ICH. Continuous

It has been suggested that breast and thyroid diseases may be linked. The aim of this study was to investigate the association between benign breast disease and subsequent risk of thyroid cancer. Postmenopausal women (n = 133,875) aged 50-79 years were followed up for a mean of 14 years. Benign breast disease was defined by history of biopsy. Incident thyroid cancer cases were confirmed by medical record review. Multivariable Cox proportional hazard modeling was used to estimate hazard ratios. There were 370 incident thyroid cancer cases during the follow-up period. Compared to women without BBD, women with BBD had a significant increased risk of thyroid cancer after adjusting for potential confounders (HR 1.38 95% CI 1.10-1.73), especially for women with more than two biopsies (HR 1.59 95% CI 1.10-2.26). There were no significant differences in thyroid tumor size, stage or histologic types between women with and without BBD. Our large prospective study observed that postmenopausal women with BBD had an increased risk for thyroid cancer compared with women without BBD. A more detailed investigation of thyroid cancer risk according to different subtypes of benign breast disease is needed to better understand the association observed between thyroid and benign breast diseases.

As an alternative approach, administration of phytotherapeutic agents in management of benign prostate hyperplasia (BPH), is rapidly growing each day. Different authors have indicated effectiveness of Viola odorata L. (Violaceae), Echium amoenum Fisch. & C.A.Mey. (Boraginaceae) and Physalis alkekengi L. (Solanaceae) in treatment of BPH. However, none have reported the beneficial outcomes of the mixture yet. This study evaluates the therapeutical effects of V. odorata, E. amoenum and P. alkekengi mixture on symptomatic BPH patients. Eighty six symptomatic BPH patients with International Prostate Symptom Score (IPSS) of more than 13 and prostate volume of more than 30 cm 3 were randomly allocated to receive a two-week course of placebo (control group) or 1 mL of mixed hydro-alcoholic solution of P. alkekengi, E. amoenum and V. odorata extracts (1.5, 1 and 1.5% respectively) (treatment group). IPSS score of incomplete urination (42.3 ± 2.04%), frequency of urination (20.08 ± 1.02%), intermittency (40.78 ± 2.16%), urgency (60.91 ± 3.14%), weak stream (50.58 ± 2.14%), straining (55.67 ± 2.53%) and nocturia (40.14 ± 1.89%) in treatment group were significantly decreased after treatment compare to placebo receiving group. Furthermore, the prostate volume (16.92 ± 0.89%) and extant urine volume (28.12 ± 1.36%) also significantly decreased in treatment group compared to control group. No significant side effects or abnormalities in biochemical tests and urinalysis were observed throughout the study. Based on results, mentioned mixture is safe and effective in improving life quality of patients suffering from BPH.

This study was undertaken to determine the incidence of subsequent oophorectomy due to ovarian pathology or ovarian cancer in women with prior hysterectomy for benign gynecologic conditions at Chiang Mai University Hospital. Medical records of women who underwent hysterectomy for benign gynecologic diseases and pre-cancerous lesions between January 1, 2004 and December 31, 2013 at Chiang Mai University Hospital were retrospectively reviewed. The incidence and indications of oophorectomy following hysterectomy were analyzed. During the study period, 1,035 women had hysterectomy for benign gynecologic conditions. Of these, 590 women underwent hysterectomy with bilateral salpingo-oophorectomy and 445 hysterectomy with bilateral ovarian preservation or unilateral salpingo-oophorectomy. The median age was 47 years (range, 11-75 years). Ten women (2.45 %) had subsequent oophorectomy for benign ovarian cysts. No case of ovarian cancer was found. The mean time interval between hysterectomy and subsequent oophorectomy was 43.1 months (range, 2-97 months) and the mean follow-up time for this patient cohort was 51 months (range, 1.3-124.9 months). According to our hospital-based data, the incidence of subsequent oophorectomy in women with prior hysterectomy for benign gynecologic conditions is low and all present with benign conditions.

Benign external hydrocephalus is defined as a rapidly increasing head circumference (occipitofrontal circumference) with characteristic radiological findings of increased subarachnoid cerebrospinal fluid spaces on neuroimaging. The incidence of benign external hydrocephalus has not been previously reported, and there is no available information on the ratio of benign external hydrocephalus in the population of hydrocephalic children. This study is retrospective and population-based study, geographically covering two health regions in the southern half of Norway with a total mean population of 3.34 million in the ten-year study period, constituting approximately 75% of the Norwegian population. Children with a head circumference crossing two percentiles, or greater than the 97.5th percentile, and with typical imaging findings of enlarged frontal subarachnoid spaces with or without enlarged ventricles were included. Children were excluded if they had a history of head trauma, intracranial hemorrhage, central nervous system infection, other known causes of hydrocephalus, or were born preterm defined as birth before 37 weeks of gestation. A total of 176 children fitting the criteria were identified, giving an incidence of 0.4 per 1000 live births. One hundred fifty-two (86.4%) of the patients were male, and mean age at referral was 7.3 months. Increasing head circumference was the main reason for referral in 158 (89.8%) patients and the only finding in 60 (34.1%) patients. Thirty-seven (21%) children had normal ventricles on imaging; the remainder had increased ventricular size. The incidence of pediatric hydrocephalus in Norway is reported to be 0.75 per 1000 live births, thus benign external hydrocephalus accounts for approximately 50% of hydrocephalic conditions in this population. The incidence of benign external hydrocephalus was found to be 0.4 per 1000 live births in this population. Copyright © 2017 The Authors. Published by Elsevier Inc. All rights

Benign anastomotic stricture after transhiatal oesophagectomy and gastric tube reconstruction constitutes a major problem. From August 1988 to April 1991, 81 patients were followed after cervical oesophagogastrostomy. Twenty-four patients (30 per cent) developed a benign anastomotic stricture 3-23 (median 8) weeks after operation. Poor vascularization of the gastric tube, determined during operation, and postoperative anastomotic leakage were statistically significant risk factors for stricture formation. Symptoms related to stricture were often typical and were confirmed by endoscopy and/or radiography. Radiography did not yield information additional to that obtained from endoscopy. Strictures were treated in the outpatient clinic by dilatation with Savary dilators. Repeated dilatation completely alleviated dysphagia in 20 of the 24 patients (83 per cent). In ten patients dilatations could be discontinued after a median of 8 (range 1-17) sessions. Dilatation was continued until the end of follow-up in nine patients or until death from recurrent disease in five. No complications of dilatation were seen.

Pancreatic resections for benign diseases may lead to long-term endocrine/exocrine impairment. The aim of this study was to compare postoperative and long-term results after different pancreatic resections for benign disease. Between 1990 and 1999, 62 patients underwent pancreaticoduodenectomy (PD), 36 atypical resection (AR) and 64 left pancreatectomy (LP) for benign tumours. Exocrine and endocrine pancreatic function was evaluated by 72-h faecal chymotrypsin and oral glucose tolerance test. The incidence of pancreatic fistula was significantly higher after AR than after LP (11 of 36 versus seven of 64; P = 0.028). The long-term incidence of endocrine pancreatic insufficiency was significantly lower after AR than after PD (P insufficiency was more common after PD (P endocrine and exocrine insufficiency was higher for PD and LP than for AR (32, 27 and 3 per cent respectively at 1 year; 58, 29 and 3 per cent at 5 years; P pancreatic resections are associated with different risks of developing long-term pancreatic insufficiency. AR represents the best option in terms of long-term endocrine and exocrine function, although it is associated with more postoperative complications.

Pneumatosis intestinalis in children is associated with a wide variety of underlying conditions and often has a benign course. The CT features of this condition have not been systematically investigated. Defining benign pneumatosis intestinalis as pneumatosis intestinalis that resolved with medical management alone, we sought to: (1) determine whether the incidence of benign pneumatosis intestinalis had increased at our pediatric cancer hospital; (2) characterize CT features of benign pneumatosis intestinalis; and (3) determine the relationship between imaging features and clinical course of benign pneumatosis intestinalis in this cohort. Radiology reports from November 1994 to December 2006 were searched for ''pneumatosis intestinalis,'' ''free intraperitoneal air,'' and ''portal venous air or gas.'' Corresponding imaging was reviewed by two radiologists who confirmed pneumatosis intestinalis and recorded the presence of extraluminal free air, degree of intramural gaseous distension, number of involved bowel segments, and time to pneumatosis resolution. The search revealed 12 boys and 4 girls with pneumatosis intestinalis; 11 were hematopoietic stem cell transplant recipients. The annual incidences of benign pneumatosis have not changed at our institution. Increases in intramural distension marginally correlated with the number of bowel segments involved (P=0.08). Three patients had free air and longer times to resolution of pneumatosis (P=0.03). Male children may be at increased risk of benign pneumatosis intestinalis. The incidence of benign pneumatosis at our institution is proportional to the number of hematopoietic stem cell transplants. The degree of intramural distension may correlate with the number of bowel segments involved. Patients with free air have a longer time to resolution of benign pneumatosis. (orig.)

In this study, we sought to define the incidence of benign renal tumors in our institute and to clarify the clinical factors associated with benign renal tumors, in order to assist in forming preoperative differential diagnoses. From October 2002 to July 2007, we performed 157 nephrectomies in patients preoperatively diagnosed with renal cell carcinoma. We chose 81 tumors, all of which were less than 5 cm, for further study. We reviewed double-phase helical CT imaging retrospectively, specifically focusing on attenuation patterns and homogeneity. We also compared clinical factors, including age, sex and tumor size, between the benign and malignant renal tumors. The patient's median age was 67 years (mean age, 63 years), and the median tumor diameter was 3.0 cm (mean, 3.2 cm). Benign renal tumors were found in 10 (12%) of the 81 tumors; these included seven cases of oncocytoma and three cases of angiomyolipoma with minimal fat. Several factors were significant clinical determinants of differentiation between benign and malignant renal tumors: homogeneity in CT, female gender, and small tumor size all predominated in cases of benign tumors. Attenuation pattern in CT, however, was not a significant factor (p=0.344). When a patient, especially a female, presents with a small and homogeneous renal tumor, careful consideration should be given to the possibility of a benign process, which needs further consideration before performing excessive surgery.

Interventional bronchoscopy is effective in the management of patients with symptomatic airway obstruction for both malignant and benign conditions. The main aim of this study is to report our experience with emergency interventional bronchoscopy in patients with symptomatic airway obstruction and identify prognostic factors for survival. This is a retrospective observational study of patients undergoing emergency interventional bronchoscopy over a 4-year period. Survival times were analyzed separately for patients with benign and malignant airway obstruction by the Kaplan-Meier method. Between June 2009 and July 2013, 168 emergency interventional bronchoscopies were performed in 112 patients for airway obstruction. The median age was 63 years (range, 20 to 86), and 91 patients (54%) patients were female. Seventy-two cases (43%) had airway obstruction due to malignant disease. There were 3 in-hospital deaths (2.7%). Median survival of the study population was 5.6 months (range, 0 to 51) with a median follow-up of 7.3 months (range, 0 to 51). Median survival for patients with malignant airway obstruction was 3.5 months (range, 0 to 21), and 9.8 months (range, 0.1 to 51) for those with benign disease. Airway intervention facilitated palliative chemotherapy in 32 patients (44%) of those with malignant airway obstruction. At multivariate analysis in patients with malignant airway obstruction, presence of stridor (hazard ratio 1.919, 95% confidence interval: 1.082 to 3.404, p = 0.026) and not receiving postprocedure chemotherapy (hazard ratio 2.05, 95% confidence interval: 1.156 to 3.636, p = 0.014) were independent prognostic factors for death. Emergency interventional bronchoscopy for airway obstruction is safe, relieved symptoms, and facilitated palliative chemotherapy, which improved survival.

To evaluate the incidence of acute symptomatic urolithiasis in the Auckland region. Associated epidemiological factors and stone characteristics were also studied and compared to previous research conducted in order to analyse trends. All patients that presented acutely with symptomatic urolithiasis to the Auckland District Health Board (AHDB) between July 2014 and June 2015 were studied. Clinical data was obtained from medical records and population data was based on estimates provided by the Ministry of Health. Two-tailed tests and the Pearson Chi-Square tests were used for analysis. Overall, 1,125 patients (1,328 events) presented with an incidence of 85 per 100,000 per year, which was lower than that reported in 2006. The highest incidence was found among the Middle Eastern ethnic subgroup (0.130 %), followed by Māori (0.102%), Asian (0.087%), European (0.084%) and Pacific (0.041%) ethnicity. Males were more likely to be affected than females. Urolithiasis was most common in the fifth decade of life (25%). Forty-seven percent of the study population presented with multiple stones and 64% had recurrent urolithiasis or were 'high risk' stone formers. Distal ureteric stones Auckland. This deviation could be attributed to the large influx of Asian immigrants observed in this period of time. A caucasian male, between 40-49 years, with a calculus <5mm in the distal ureter with a history of a previous urolithiasis has the highest chance to present with renal colic.

Benign pancreatic tumors should undergo surgical resection when they are symptomatic or - in the case of incidental discovery - bear malignant potential. This is the case for the majority of benign pancreatic tumors, especially for intraductal papillary mucinous neoplasms or mucinous cystic adenomas. In addition, resection is indicated for all tumors where preoperative diagnostic fails to provide an exact classification. Several different operative techniques are available. The treatment of choice depends on the localization of the tumor, its size and on whether there is evidence of malignant transformation. Partial duodenopancreatectomy is the oncological treatment of choice for tumors of the pancreatic head whereas for tumors of the pancreatic tail a left-sided pancreatectomy is appropriate. Middle pancreatectomy or duodenum-preserving resection of the pancreatic head is not a radical oncologic procedure. They should only be performed in cases of tumors without malignant potential. (orig.) [German] Die Indikationsstellung zur Resektion benigner Pankreastumoren ist gegeben, wenn es sich um einen symptomatischen Tumor handelt oder - bei einem Zufallsbefund - um einen Tumor mit Potenzial zur malignen Entartung. Dies besteht bei der Mehrzahl der benignen Pankreastumoren, insbesondere bei der intraduktalen papillaeren muzinoesen Neoplasie (IPMN) oder muzinoesen Zystadenomen. Operativer Abklaerung beduerfen auch Tumoren, die unter Ausschoepfung aller diagnostischer Moeglichkeiten nicht eindeutig klassifizierbar sind. An chirurgischen Therapieverfahren stehen verschiedene Techniken zur Verfuegung. Die Wahl des Verfahren haengt von der Groesse und Lokalisation des Tumors ab und von der Frage, ob eine maligne Entartung bereits stattgefunden hat. Das onkologisch korrekte Standardresektionsverfahren bei Tumoren des Pankreaskopfes ist die partielle Duodenopankreatektomie, bei Tumoren des Pankreasschwanzes die Pankreaslinksresektion.

Objective: To determine the frequencies of various benign breast diseases (BBD) in female patients in three private hospitals of Hyderabad. Methodology: This is a prospective cohort study of all female patients visiting the surgical clinic with breast problems. This study was conducted at Isra University Hospital Hyderabad and two other private hospitals of Hyderabad over a period of about three years starting from March 2004 to February 2007. All female patients visiting the surgical clinic with breast problems were included in the study. Patients with obvious clinical features of malignancy or those who on work up were diagnosed as carcinoma were excluded from the study. Results: A total of 275 patients were included in the study. About 44% (120/275) patients belonged to third decade of life (age between: 21-30 years) followed by 33% from forth decade (age between: 31- 40 years). Fibroadenoma was the most common benign breast disease, seen in 27% (75/275) of patients, followed by fibrocystic disease seen in about 21% (57/275) patients. Conclusion: Benign Breast Diseases (BBD) are common problems in females of reproductive age. Fibroadenoma is the commonest of all benign breast disease in our set up mostly seen in second and third decade of life. Fibrocystic disease of the breast is the next common BBD whose incidence increases with increasing age. (author)

During the years 1949 to 1975, 14,237 patients received therapeutic doses of grenz rays for the treatment of benign skin disorders such as chronic eczema, psoriasis, and warts. The records of 14,140 of these patients (99.3%) formed the basis for an epidemiologic study of the incidence of skin malignancies in this population. Information about the patients, diagnoses, doses, and sites of treatment was obtained from separate records. The follow-up time was 15 years on the average. We searched the Swedish Cancer Registry, Stockholm, for records reporting the incidence of malignant skin tumors in the study population (incidences of basal cell carcinoma are not registered). The expected number of malignancies was calculated on the basis of age- and sex-standardized incidence data from the Swedish Cancer Registry. In 58 patients, a malignant skin tumor was diagnosed more than five years after grenz-ray therapy had first been administered. Nineteen patients had malignant melanomas, and 39 patients had other malignant skin tumors. The expected number of melanomas was 17.8, and that of other malignant skin tumors was 26.9. None of the patients with melanomas, and only eight of the patients with other malignant skin tumors, had received grenz-ray therapy at the site of the tumor. Six of these eight patients had also been exposed to other known carcinogens. Four hundred eighty-one patients had received an accumulated high dose of grenz rays (greater than or equal to 10 000 rad [greater than or equal to 100 Gy]) on one and the same area. No malignancies were found on those areas. Although we cannot exclude grenz-ray therapy as a risk factor in the development of nonmelanoma skin malignancies, this risk, if any, is small, if recommendations for therapy are followed

Urinary tract infections, including pyelonephritis, are serious complications that may lead to significant maternal and neonatal morbidity and mortality. There is a large number of drugs, and combination of them, available to treat urinary tract infections, most of them tested in non-pregnant women. Attempts to define the optimal antibiotic regimen for pregnancy have, therefore, been problematic. The objective of this review was to determine, from the best available evidence from randomised controlled trials, which agent is the most effective for the treatment of symptomatic urinary tract infections during pregnancy in terms of cure rates, recurrent infection, incidence of preterm delivery and premature rupture of membranes, admission to neonatal intensive care unit, need for change of antibiotic, and incidence of prolonged pyrexia. We searched the Cochrane Pregnancy and Childbirth Group Trials Register (November 2009) and reference lists of articles. We considered all trials where the intention was to allocate participants randomly to one of at least two alternative treatments for any symptomatic urinary tract infection. Both review authors assessed trial quality and extracted data. We included 10 studies, recruiting a total of 1125 pregnant women. In most of the comparisons there were no significant differences between the treatments under study with regard to cure rates, recurrent infection, incidence of preterm delivery, admission to neonatal intensive care unit, need for change of antibiotic and incidence of prolonged pyrexia. When cefuroxime and cephradine were compared, there were better cure rates (29/49 versus 41/52) and fewer recurrences (20/49 versus 11/52) in the cefuroxime group. There was only one other statistically significant difference when comparing outpatient versus inpatient treatment. Gestational age at birth was greater in women from the outpatient group (38.86 versus 37.21), while birthweight was on average greater in the inpatient group

As prostate artery embolisation (PAE) becomes an established treatment for benign prostatic obstruction, factors predicting good symptomatic outcome remain unclear. Pre-embolisation prostate size as a predictor is controversial with a handful of papers coming to conflicting conclusions. We aimed to investigate if an association existed in our patient cohort between prostate size and clinical benefit, in addition to evaluating percentage volume reduction as a predictor of symptomatic outcome following PAE. Prospective follow-up of 86 PAE patients at a single institution between June 2012 and January 2016 was conducted (mean age 64.9 years, range 54-80 years). Multiple linear regression analysis was performed to assess strength of association between clinical improvement (change in IPSS) and other variables, of any statistical correlation, through Pearson's bivariate analysis. No major procedural complications were identified and clinical success was achieved in 72.1% (n = 62) at 12 months. Initial prostate size and percentage reduction were found to have a significant association with clinical improvement. Multiple linear regression analysis (r 2  = 0.48) demonstrated that percentage volume reduction at 3 months (r = 0.68, p < 0.001) had the strongest correlation with good symptomatic improvement at 12 months after adjusting for confounding factors. Both the initial prostate size and percentage volume reduction at 3 months predict good symptomatic outcome at 12 months. These findings therefore aid patient selection and counselling to achieve optimal outcomes for men undergoing prostate artery embolisation.

Canal switch is a complication following canalith repositioning procedure (CRP) for posterior canal benign paroxysmal positional vertigo (BPPV). Instead of being returned to the utricle, the loose otoconia migrate into the superior or horizontal semicircular canal. Patients remain symptomatic, and treatment can be ineffective unless the switch is recognized and additional repositioning maneuvers directed toward the appropriate semicircular canal are performed. This report provides the first videographic documentation of canal switch involving conversion of unilateral posterior semicircular canal BPPV to geotropic horizontal canalithiasis.

tumors among women with a benign ovarian tumor. METHODS: This nationwide cohort study included all Danish women diagnosed with a benign ovarian tumor (n=139,466) during 1978-2012. The cohort was linked to the Danish Pathology Data Bank and standardized incidence ratios (SIR) with 95% confidence intervals...... (CI) were calculated. RESULTS: Women with benign ovarian tumors had increased risks for subsequent borderline ovarian tumors (SIR 1.62, 95% CI 1.43-1.82), and this applied to both serous (SIR 1.69, 95% CI 1.39-2.03) and mucinous (SIR 1.75, 95% CI 1.45-2.10) histotypes of borderline ovarian tumors....... The risk for borderline ovarian tumors was primarily increased for women diagnosed with a benign ovarian tumor before 40years of age. The risk remained increased up to 9years after a benign ovarian tumor diagnosis. Finally, the associations did not change markedly when analyzed for the different histotypes...

Recurrent airway obstructions in a patient with benign tracheal stenosis and a silicone airway stent: a case report

Science.gov (United States)

Sriram, KB; Robinson, PC

2008-01-01

Airway stents (silicone and metal stents) are used to treat patients with benign tracheal stenosis, who are symptomatic and in whom tracheal surgical reconstruction has failed or is not appropriate. However airway stents are often associated with complications such as migration, granuloma formation and mucous hypersecretion, which cause significant morbidity, especially in patients with benign tracheal stenosis and relatively normal life expectancy. We report a patient who had frequent critical airway obstructions over 8 years due to granuloma and mucus hypersecretion in a silicone airway stent. The problem was resolved when the silicone stent was removed and replaced with a covered self expanding metal stent. PMID:18840299

Laser has been the main ablative modality in the airways, but a growing experience with endobronchial electrocautery suggests a comparable efficacy and safety profile. To evaluate the efficacy and safety of electrocautery as the primary heat therapy for malignant and benign airway obstruction. A retrospective review of all patients undergoing endobronchial electrocautery, alone or in combination with other airway tools, at Duke University Medical Center between April 2004 and November 2009. Data on efficacy (luminal patency, symptomatic, radiographic, or physiologic improvement) and safety (complication rate) were collected. Ninety-four patients underwent 117 procedures with endobronchial electrocautery for endobronchial malignant and nonmalignant disease. Endoscopic improvement was seen in 94% of cases. Seventy-one percent of patients reported symptomatic improvement. Radiographic studies demonstrated luminal improvement in 78% of patients on chest computed tomography, improved aeration on chest computed tomography and chest x-ray in 63% and 43% of patients, respectively. The rate of major complications was 0.8%, whereas minor complications occurred in 6.8% of cases. There was no perioperative mortality. Endobronchial electrocautery is effective and safe when used as an ablative modality in malignant and benign airway obstruction and has a comparable profile to laser with the advantage of lower cost.

Full Text Available Introduction. We herein report our experience with new fully covered self-expanding metallic stents in the setting of inoperable recurrent benign tracheobronchial stenosis. Methods. Between May 2010 and July 2014, 21 Micro-Tech® FC-SEMS (Nanjing Co., Republic of Korea were placed in our hospital in 16 patients for inoperable, recurrent (after dilatation, and symptomatic benign airway stenosis. Their medical files were retrospectively reviewed in December 2014, with focus on stent’s tolerance and durability data. Results. Twenty-one stents were inserted: 13 for posttransplant left main bronchus anastomotic stricture, seven for postintubation tracheal stenosis, and one for postlobectomy anastomotic stricture. Positioning was easy for all of them. Stents were in place for a mean duration of 282 days. The most common complications were granulation tissue development (35%, migration (30%, and sputum retention (15%. Fifty-five % of the stents (11/20 had to be removed because of various complications, without difficulty for all of them. None of the patients had life-threatening complications. Conclusion. Micro-Tech FC-SEMS were easy to position and to remove. While the rate of complications requiring stent removal was significant, no life-threatening complication occurred. Further studies are needed to better define their efficacy and safety in the treatment of benign airway disease.

Wang, Long; Shi, Xiang'en; Liu, Fangjun; Qian, Hai

2016-12-01

Fusiform dilation of the internal carotid artery (FDICA) is an infrequent vascular complication following resection of suprasellar lesions in the pediatric population, and its course appears to be benign without apparent clinical symptoms. However, data correlating symptomatic FDICA with bypass surgery are scarce. The authors here report 2 symptomatic cases that were treated using internal maxillary artery bypass more than 5 years after total removal of a craniopharyngioma at an outside institution. Both cases of FDICA were resected to relieve the mass effect and to expose the craniopharyngioma. The postoperative course was uneventful, and radiological imaging revealed graft conduit patency. To the authors' knowledge, this is the first reported use of extracranial to intracranial bypass to treat FDICA following removal of a suprasellar lesion. Their findings suggest that bypass surgery is a useful therapeutic approach for symptomatic cases of FDICA and total removal of recurrent craniopharyngioma. Moreover, the indications for surgical intervention and treatment modalities are discussed in the context of previous relevant cases.

The relationship between baseline prostate-specific antigen (PSA) and development of lower urinary tract symptoms (LUTS) in asymptomatic and mildly symptomatic men is unclear. We sought to determine if PSA predicts incident LUTS in these men. A post-hoc analysis of the 4-year REDUCE study was performed to assess for incident LUTS in 1534 men with mild to no LUTS at baseline. The primary aim was to determine whether PSA independently predicted incident LUTS after adjusting for the key clinical variables of age, prostate size, and baseline International prostate symptom score (IPSS). Incident LUTS was defined as the first report of medical treatment, surgery, or sustained clinically significant symptoms (two IPSS >14). Cox proportional hazards, cumulative incidence curves, and the log-rank test were used to test our hypothesis. A total of 1534 men with baseline IPSS PSA 2.5-4 ng/mL, 589 with PSA 4.1-6 ng/mL, and 610 with PSA 6-10 ng/mL. During the 4-year study, 196 men progressed to incident LUTS (50.5% medical treatment, 9% surgery, and 40.5% new symptoms). As a continuous variable, higher PSA was associated with increased incident LUTS on univariable (HR 1.09, p = 0.019) and multivariable (HR 1.08, p = 0.040) analysis. Likewise, baseline PSA 6-10 ng/mL was associated with increased incident LUTS vs. PSA 2.5-4 ng/mL in adjusted models (HR 1.68, p = 0.016). This association was also observed in men with PSA 4.1-6 ng/mL vs. PSA 2.5-4 ng/mL (HR 1.60, p = 0.032). Men with mild to no LUTS but increased baseline PSA are at increased risk of developing incident LUTS presumed due to benign prostatic hyperplasia.

Benign prostatic hyperplasia creates significant expenses for the Medicare program. We determined expenditure trends for benign prostatic hyperplasia evaluative testing after urologist consultation and placed these trends in the context of overall Medicare expenditures. Using a 5% national sample of Medicare beneficiaries from 2000 to 2007 we developed a cohort of 40,253 with claims for new visits to urologists for diagnoses consistent with symptomatic benign prostatic hyperplasia. We assessed trends in initial inflation and geography adjusted expenditures within 12 months of diagnosis by evaluative test categories derived from the 2003 American Urological Association guideline on the management of benign prostatic hyperplasia. Using governmental reports on Medicare expenditure trends for benign prostatic hyperplasia we compared expenditures to overall and imaging specific Medicare expenditures. Comparisons were assessed by the Z-test and regression analysis for linear trends, as appropriate. Between 2000 and 2007 inflation adjusted total Medicare expenditures per patient for the initial evaluation of patients with benign prostatic hyperplasia seen by urologists increased from $255.44 to $343.98 (p inflation adjusted expenditures increased for benign prostatic hyperplasia related evaluations. This growth was slower than the overall growth in Medicare expenditures. The increase in BPH related imaging expenditures was restrained compared to that of the Medicare program as a whole.

2009-01-01

This study was to investigate the role of complementary and alternative medicine in the prevention and treatment of benign prostatic hyperplasia. For this purpose, a randomized, double-blind, placebo-controlled trial was performed over 12 months on 47 benign prostatic hyperplasia patients with average age of 53.3 years and international prostate symptom score over 8. Subjects received either sweet potato starch (group A, placebo, 320 mg/day), pumpkin seed oil (group B, 320 mg/day), saw palmetto oil (group C, 320 mg/day) or pumpkin seed oil plus saw palmetto oil (group D, each 320 mg/day). International prostate symptom score, quality of life, serum prostate specific antigen, prostate volume and maximal urinary flow rate were measured. In groups B, C and D, the international prostate symptom score were reduced by 3 months. Quality of life score was improved after 6 months in group D, while those of groups B and C were improved after 3 months, compared to the baseline value. Serum prostate specific antigen was reduced only in group D after 3 months, but no difference was observed in prostate volume in all treatment groups. Maximal urinary flow rate were gradually improved in groups B and C, with statistical significance after 6 months in group B and after 12 months in group C. None of the parameters were significantly improved by combined treatment with pumpkin seed oil and saw palmetto oil. From these results, it is suggested that administrations of pumpkin seed oil and saw palmetto oil are clinically safe and may be effective as complementary and alternative medicine treatments for benign prostatic hyperplasia.

There has been no previous study to classify benign breast lesions in details based on histopathologically confirmed diagnosis in Bayelsa State, Nigeria. This study therefore aims to review all cases of benign breast lesions seen in all the three centres in Bayelsa State with histopathology services over a five year period for a comprehensive baseline data in our community for management, research and education. This is a multicentre retrospective descriptive study based on histopathological diagnosed benign breast lesions from January 2009 to December 2013. Archival results and slides on benign breast lesions were retrieved and analysed using simple statistical methods. A total of 228 benign breast lesions (68.3%) were seen among 334 histopathologically diagnosed breast diseases. The male to female ratio was 19.7:1. Peak age incidence was the third decade (43%) with a mean age of 29.1years. Fibroadenoma was the most common benign breast disease (BBD) accounting for 45.6% of all the cases followed by fibrocystic change (23.1%). The mean ages of fibroadenoma and fibrocystic change were 23.1years and 31.1years respectively. Inflammatory breast lesions constituted 8.3%. We recorded only 2 cases (0.9%) of atypical ductal hyperplasia (ADH) with no case of atypical lobular hyperplasia (ALH) within the study period. Gynaecomastia (4%) was the main male breast lesion in the study. Benign breast diseases are the most common breast lesions in Bayelsa State. Fibroadenoma is the most common lesion followed by fibrocystic change. The incidence of atypical hyperplasia recorded was rather low in the state.

During recent years, pharmacological treatment of symptomatic benign prostatic hyperplasia (BPH) has become the primary treatment choice for an increasing number of patients. The 2 principal drug classes employed are alpha 1-blockers and 5 alpha-reductase inhibitors. Current information from...... of patients who will respond well to alpha 1-blockers have yet to be identified, and data concerning the long term effects of these drugs are not yet available. 5 alpha-Reductase inhibitors have a slow onset of effect, but treatment leads to improvement in symptoms, reduction of the size of the prostate gland...... and improvement in objective parameters for bladder outflow obstruction. Approximately 30 to 50% of patients will respond to treatment with 5 alpha-reductase inhibitors. The definitive role of pharmacological treatment in symptomatic BPH remains to be established, although it seems that patients unfit...

Benign prostate hyperplasia (BPH) occurs in up to 50% of men by age 50, and the incidence increases with age. This common clinical problem is diagnosed by history, including the International Prostate Symptom Score (IPSS) questionnaire, and physical examination by digital rectal examination (DRE). Initial management for BPH includes lifestyle modification, and smooth muscle relaxant alpha blocker therapy. Alpha blockers usually take effect quickly within 3-5 days, and have minimal side effects. Current commonly used alpha blockers include the selective alpha blockers tamsulosin (Flomax), alfusosin (Xatral), and silodosin (Rapaflo). For patients with larger prostates, the 5-alpha reductase inhibitor class (finasteride (Proscar) and dutasteride (Avodart)) work effectively to shrink prostate stroma resulting in improved voiding. The 5-ARI class of drugs, in addition to reducing prostate size, also reduce the need for future BPH-related surgery, and reduce the risk of future urinary retention. Drugs from the phosphodiesterase-5 (PDE-5) inhibitor class may now be considered for treating BPH. Once daily 5 mg tadalafil has been shown to improve BPH-related symptoms and is currently approved to treat patients with BPH. Referral to a urologist can be considered for patients with a rising prostate-specific antigen (PSA), especially while on 5-ARI, failure of urinary symptom control despite maximal medical therapy, suspicion of prostate cancer, hematuria, recurrent urinary infections, urinary retention, or renal failure. Currently the primary care physician is armed with multiple treatment options to effectively treat men with symptomatic BPH.

Postoperative benign biliary stricture in the anastomotic site is one of the most common complications of biliary-enteric anastomosis, with a rate of 6.87% after 2-13 years of follow-up. If untreated, biliary strictures can induce other complications such as recurrent cholangitis, intrahepatic stones, pancreatitis and secondary biliary cirrhosis. We report our experience with extracorporeal shock wave lithotripsy (ESWL) in a patient with a massive symptomatic stone proximal to an anastomotic biliary stricture.

The aim of this study was to determine trends in the incidence of benign lesions in patients undergoing surgery for suspicious renal masses on preoperative computed tomography scan. The records of 1065 patients who underwent open consecutive partial nephrectomy (PN) or radical nephrectomy (RN) between January 2001 and December 2008 were reviewed. Patients who underwent PN during the periods 2001-2002, 2003-2004, 2005-2006, and 2007-2008 were assigned to groups 1, 2, 3 and 4, respectively. The frequencies of benign and malignant lesions in these groups were assessed according to size and histology subtypes. The ratio of PN to RN was 12.4%, 18.3%, 24.3% and 37.2% in groups 1, 2, 3 and 4, respectively (P<0.05). The mean size of resected lesions was 2.6 cm (range 0.8-6.2 cm). Of the 290 cases, histopathology revealed benign findings in 52 (17.9%). Benign pathology was found in three of 18 cases (16.7%) in group 1, seven of 36 cases (19.4%) in group 2, 12 of 63 cases (19.0%) in group 3 and 30 of 173 cases (17.3%) in group 4. There was no significant difference in the frequency of benign histology among groups. PN, as opposed to RN, has shown a rising tendency over time. The frequency of benign pathology findings after PN for suspicious renal masses on preoperative computed tomography imaging has not decreased. Proper management should favor nephron-sparing surgery for renal lesions if such lesions can be removed satisfactorily with PN. (author)

Benign prostatic hyperplasia and hypogonadism are common disorders in aging men. There is concern that androgen replacement in older men may increase prostate size and symptoms of benign prostatic hyperplasia. We examined whether combining dutasteride, which inhibits testosterone to dihydrotestosterone conversion, with testosterone treatment in older hypogonadal men with benign prostatic hyperplasia reduces androgenic stimulation of the prostate compared to testosterone alone. We conducted a double-blind, placebo controlled trial of 53 men 51 to 82 years old with symptomatic benign prostatic hyperplasia, prostate volume 30 cc or greater and serum total testosterone less than 280 ng/dl (less than 9.7 nmol/l). Subjects were randomized to daily transdermal 1% T gel plus oral placebo or dutasteride for 6 months. Testosterone dosing was adjusted to a serum testosterone of 500 to 1,000 ng/dl. The primary outcomes were prostate volume measured by magnetic resonance imaging, serum prostate specific antigen and androgen levels. A total of 46 subjects completed all procedures. Serum testosterone increased similarly into the mid-normal range in both groups. Serum dihydrotestosterone increased in the testosterone only but decreased in the testosterone plus dutasteride group. In the testosterone plus dutasteride group prostate volume and prostate specific antigen (mean ± SEM) decreased 12% ± 2.5% and 35% ± 5%, respectively, compared to the testosterone only group in which prostate volume and prostate specific antigen increased 7.5% ± 3.3% and 19% ± 7% (p = 0.03 and p = 0.008), respectively, after 6 months of treatment. Prostate symptom scores improved in both groups. Combined treatment with testosterone plus dutasteride reduces prostate volume and prostate specific antigen compared to testosterone only. Coadministration of a 5α-reductase inhibitor with testosterone appears to spare the prostate from androgenic stimulation during testosterone replacement in older

To determine the prevalence and associated clinical symptoms of pes anserine bursitis in symptomatic adult knees. A retrospective review was performed of the reports of 509 knee MRI studies obtained from July 1998 to June 2004 on 488 patients presenting to an orthopaedic clinic with knee pain suspected to be due to internal derangement. The MRI studies and case histories of all patients reported to have pes anserine bursitis were reviewed. The management of these patients was also noted. The prevalence of pes anserine bursitis as detected on MRI is 2.5%. The commonest clinical presentation was pain along the medial joint line mimicking a medial meniscal tear. We suggest that an accurate diagnosis of pes anserine bursitis on MRI will help prevent unnecessary arthroscopy and possibly initiate early treatment of the condition. Axial imaging is important in these cases to differentiate the bursa from other medial fluid collections. (orig.)

Full Text Available Multiple sclerosis (MS, an inflammatory autoimmune disease, affects almost 1% of world’s population in which myelin sheaths of neurons are targeted by immune cells. Association of different factors and diseases with MS provides new insights into possible pathogenesis and treatment for this disease. In this regard, we investigated the association of benign tumors with MS disease by studying total Isfehan multiple sclerosis (TIMS records for MS patients registered in Isfahan Multiple Sclerosis Society (IMSS who had developed any kind of benign tumors whether before MS diagnosis or after it. This study was performed in Isfahan province, third large province of Iran, with 4,815,863 populations located 1590 meters above sea level between latitudes 30 and 34 degrees north of the equator, and longitude 49-55 east. Among 4950 registered patients, 28 patients were discovered to have three types of benign tumors; pituitary adenoma in 22, meningioma in 5 and lipoma in 1 patient. The incidence rate of developing pituitary adenoma and meningioma were higher than in general population (OR 95%CI: 1.110; range: 0.731-1.685 and 1.035; range: 0.431-2.487 respectively but these findings were not statistically significant (p= 0.624 for pituitary adenoma and p= 0.939 for meningioma. But the incidence rate for lipoma was lower among MS patients (OR 95%CI: 0.020; range: 0.003-0.143 which was statistically significant (p <0.001.

Our aim was to ascertain the incidence of, reasons for, and risk factors associated with hospital readmission after an operation for benign distal esophageal disease. Using the American College of Surgeons National Surgical Quality Improvement Program database (2012-2014), patients with a primary diagnosis of gastroesophageal reflux disease, paraesophageal hiatal hernia, or achalasia who underwent fundoplication, paraesophageal hernia repair, or Heller myotomy were identified. The primary outcome was hospital readmission. Multivariable logistic regression analysis was used to identify risk factors associated with hospital readmission. Of the 14,478 patients included in this study, 801 (5.5%) were readmitted at a median of 11 days (interquartile range 6-17) postprocedure. Intolerance of oral intake (21.8%), respiratory complications (11.6%), abdominal pain (6.0%), and venous thromboembolic events (4.7%) were some of the most common reasons for readmission. Open operative approach (odds ratio 1.34, 95% confidence interval 1.05-1.71), chronic steroid use (odds ratio 1.48, 95% confidence interval 1.10-2.00), emergency admission (odds ratio 1.50, 95% confidence interval 1.01-2.21), and predischarge complication (odds ratio 1.91, 95% confidence interval 1.42-2.59) were associated most strongly with hospital readmission. Implementing standardized perioperative strategies, such as nutritional counseling, early ambulation, intensive pulmonary toilet, and deep vein thrombosis prophylaxis, may help decrease the number of preventable readmissions and enhance the overall quality of care in this patient population.

2018-01-01

Full Text Available Multiphoton microscopy has attracted increasing attention and investigations in the field of breast cancer, based on two-photon excited fluorescence (TPEF and second-harmonic generation (SHG. However, the incidence of breast benign diseases is about 5 to 10 times higher than breast cancer; up to 30% of women suffer from breast benign diseases and require treatment at some time in their lives. Thus, in this study, MPM was applied to image fibroadenoma and fibrocystic lesion, which are two of the most common breast benign diseases. The results show that MPM has the capability to identify the microstructure of lobule and stroma in normal breast tissue, the interaction of compressed ducts with surrounding collagen fiber in fibroadenoma, and the architecture of cysts filled with cystic fluid in fibrocystic disease. These findings indicate that, with integration of MPM into currently accepted clinical imaging system, it has the potential to make a real-time diagnosis of breast benign diseases in vivo, as well as breast cancer.

Purpose: To investigate predictive factors in the development of symptomatic radiation injury after treatment with linear accelerator–based stereotactic radiosurgery for intracerebral arteriovenous malformations and relate the findings to the conclusions drawn by Quantitative Analysis of Normal Tissue Effects in the Clinic (QUANTEC). Methods and Materials: Archived plans for 73 patients who were treated at the British Columbia Cancer Agency were studied. Actuarial estimates of freedom from radiation injury were calculated using the Kaplan-Meier method. Univariate and multivariate Cox proportional hazards models were used for analysis of incidence of radiation injury. Log–rank test was used to search for dosimetric parameters associated with freedom from radiation injury. Results: Symptomatic radiation injury was exhibited by 14 of 73 patients (19.2%). Actuarial rate of symptomatic radiation injury was 23.0% at 4 years. Most patients (78.5%) had mild to moderate deficits according to Common Terminology Criteria for Adverse Events, version 4.0. On univariate analysis, lesion volume and diameter, dose to isocenter, and a V x for doses ≥8 Gy showed statistical significance. Only lesion diameter showed statistical significance (p 5 cm 3 and diameters >30 mm were significantly associated with the risk of radiation injury (p 12 also showed strong association with the incidence of radiation injury. Actuarial incidence of radiation injury was 16.8% if V 12 was 3 and 53.2% if >28 cm 3 (log–rank test, p = 0.001). Conclusions: This study confirms that the risk of developing symptomatic radiation injury after radiosurgery is related to lesion diameter and volume and irradiated volume. Results suggest a higher tolerance than proposed by QUANTEC. The widely differing findings reported in the literature, however, raise considerable uncertainties.

Intracranial developmental venous anomalies (DVAs) are considered benign vascular dispositions; they are asymptomatic in the vast majority of cases. They represent extreme variations of the venous drainage and may rarely be responsible for focal venous ischemia leading to neurological dysfunction. The aim of the study is to analyze a group of patients with symptomatic DVAs with capillary stain at angiography. We retrospectively reviewed the clinical and radiological features of patients in which a DVA was considered the cause of a neurological event. In all the patients, the DVA was suspected by angio-CT or MRI and conventional angiography was performed to detail the angioarchitecture of the DVA. A total of 7 patients and 11 DVAs were identified; three patients had multiple DVAs. Three DVAs were frontal, two were parietal, two were thalamic, one was in the midbrain, and three were cerebellar. Patients presented with progressive neurological deficits, seizures, or cerebral hemorrhage. All these DVAs were associated with a peculiar capillary stain at angiography. Although being normal anatomical variations, DVAs may create, because of hemodynamic unbalance, venous ischemia that induces angiogenic phenomena. MRI shows the suffering of the brain and angiography witnesses this angiogenesis under the form of capillary stain. Conventional angiography can thus provide useful information to recognize ''atypical'' symptomatic DVAs. (orig.)

Subependymomas are benign intraventricular tumors with an indolent growth pattern, which are usually asymptomatic, and most commonly occur in the fourth and lateral ventricles. When symptomatic, subependymomas often obstruct critical portions of the cerebrospinal fluid (CSF) pathway, causing hydrocephalus, and range from 3 cm to 5 cm in size. We report a case of an unusually massive subependymoma of the lateral ventricles treated with subtotal resection, ventriculoperitoneal shunt, and post-surgical radiation. The clinical course, radiographic and pathologic characteristics of this massive intraventricular subependymoma are discussed, as well as the differential diagnosis of lateral ventricular masses and a review of the literature concerning subependymomas.

The influence of asymptomatic inflammatory prostatitis on the onset and progression of lower urinary tract symptoms in men with histologic benign prostatic hyperplasia

Directory of Open Access Journals (Sweden)

Rikiya Taoka

2017-07-01

Full Text Available Benign prostatic hyperplasia (BPH is a condition that greatly affects the quality of life of middle-aged and elderly men. Histopathologically, hyperplastic changes frequently occur in the prostate tissue of elderly men, the incidence of which has been reported to reach approximately 80% in men in their 70s. In clinical practice, approximately 25% of men with histologic BPH are assumed to experience lower urinary tract symptoms (LUTS and receive some kind of treatment. In other words, there are some men with histologic BPH who do not exhibit LUTS. For that reason, many factors, such as the change in hormonal environment, the immune or autoimmune response, the alteration of gene expression, and so on, are thought to affect the onset and progression of LUTS in men with histologic BPH. One such factor that has long drawn attention is the presence of asymptomatic histological inflammation, which very often accompanies symptomatic BPH. Recent studies have suggested that asymptomatic histological inflammation causes repeated destruction, healing, and regeneration of the prostate tissue, leading to the enlargement of prostatic nodules, while at the same time causing stromal tissue-predominant remodeling of the prostate tissue, which can increase urination resistance and result in the condition changing from asymptomatic BPH to symptomatic BPH. In future, the biomolecular clarification of the significance of asymptomatic histological inflammation in the prostate tissue could help develop new treatment strategies for BPH accompanied by LUTS.

To test the hypothesis that a common iliac vein (CIV) stenosis may impair embolization of a large deep venous thrombosis (DVT) to the lungs, decreasing the incidence of a symptomatic pulmonary embolism (PE). Between January 2002 and August 2007, 75 patients diagnosed with unilateral DVT were included in a single-institution case-control study. Minimum CIV diameters were measured 1 cm below the inferior vena cava (IVC) bifurcation on computed tomography (CT) images. A significant stenosis in the CIV ipsilateral to the DVT was defined as having either a diameter 4 mm or less or a greater than 70% reduction in lumen diameter. A symptomatic PE was defined as having symptoms and imaging findings consistent with a PE. The odds of symptomatic PE versus CIV stenosis were assessed using logistic regression models. The associations between thrombus location, stenosis, and symptomatic PE were assessed using a stratified analysis. Of 75 subjects, 49 (65%) presented with symptomatic PE. There were 17 (23%) subjects with a venous lumen 4 mm or less and 12 (16%) subjects with a greater than 70% stenosis. CIV stenosis of 4 mm or less resulted in a decreased odds of a symptomatic PE compared with a lumen greater than 4 mm (odds ratio [OR] 0.17, P = .011), whereas a greater than 70% stenosis increased the odds of DVT involving the CIV (OR 7.1, P = .047). Among patients with unilateral DVT, those with an ipsilateral CIV lumen of 4 mm or less have an 83% lower risk of developing symptomatic PE compared with patients with a CIV lumen greater than 4 mm.

Schnarr, J; Smaill, F

2008-10-01

Symptomatic and asymptomatic bacteriuria is common in pregnant women. A history of previous urinary tract infections and low socioeconomic status are risk factors for bacteriuria in pregnancy. Escherichia coli is the most common aetiologic agent in both symptomatic and asymptomatic infection and quantitative culture is the gold standard for diagnosis. Treatment of asymptomatic bacteriuria has been shown to reduce the rate of pyelonephritis in pregnancy and therefore screening for and treatment of asymptomatic bacteriuria has become a standard of obstetrical care. Antibiotic treatment of asymptomatic bacteriuria is associated with a decrease in the incidence of low birth weight, but the methodological quality of the studies limits the strength of the conclusions that can be drawn. Debate exists in the literature as to whether treated pyelonephritis is associated with adverse fetal outcomes. There is no clear consensus in the literature on antibiotic choice or duration of therapy for infection. With increasing antibiotic resistance, consideration of local resistance rates is necessary when choosing therapy.

Saw palmetto is used by over 2 million men in the United States for the treatment of benign prostatic hyperplasia and is commonly recommended as an alternative to drugs approved by the Food and Drug Administration. In this double-blind trial, we randomly assigned 225 men over the age of 49 years who had moderate-to-severe symptoms of benign prostatic hyperplasia to one year of treatment with saw palmetto extract (160 mg twice a day) or placebo. The primary outcome measures were changes in the scores on the American Urological Association Symptom Index (AUASI) and the maximal urinary flow rate. Secondary outcome measures included changes in prostate size, residual urinary volume after voiding, quality of life, laboratory values, and the rate of reported adverse effects. There was no significant difference between the saw palmetto and placebo groups in the change in AUASI scores (mean difference, 0.04 point; 95 percent confidence interval, -0.93 to 1.01), maximal urinary flow rate (mean difference, 0.43 ml per minute; 95 percent confidence interval, -0.52 to 1.38), prostate size, residual volume after voiding, quality of life, or serum prostate-specific antigen levels during the one-year study. The incidence of side effects was similar in the two groups. In this study, saw palmetto did not improve symptoms or objective measures of benign prostatic hyperplasia.

Full Text Available Elastofibroma dorsi is an uncommon benign soft tissue pseudotumour usually located at the lower pole of the scapula, deep to serratus anterior, and often attached to the periosteum of the ribs, presenting with long history of swelling and occasionally pain and discomfort. This lesion is usually seen in patients over the age of 50 years and is not uncommonly mistaken as a malignant tumour because of its size and location deep to the periscapular muscles. Review of the orthopaedic oncology database of 17 500 patients revealed that there were 15 patients with elastofibroma dorsi. There were 12 males and 3 females, mean age at diagnosis of 68.4 years range 51–79 years. The diagnosis was confirmed by MRI in 3 patients, excision biopsy in 3 patients, trucut biopsy in 8 patients and open biopsy in 1 patient. Eight patients had excision of the lesion which was symptomatic. There have been no recurrences. We highlight the clinical and radiological presentation of elastofibroma dorsi to increase awareness of its existence and management.

Full Text Available Despite using imaging studies, tissue sampling, and serologic tests about 5–10% of surgeries done for presumed pancreatic malignancies will have benign findings on final pathology. Endoscopic ultrasound (EUS is used with increasing frequency to study pancreatic masses. The aim of this study is to examine the effect of EUS on prevalence of benign diseases undergoing Whipple over the last decade. Patients who underwent Whipple procedure for presumed malignancy at Emory University Hospital from 1998 to 2011 were selected. Demographic data, history of smoking and drinking, history of diabetes and pancreatitis, imaging data, pathology reports, and tumor markers were extracted. 878 patients were found. 95 (10.82% patients had benign disease. Prevalence of benign finding had increased over the recent years despite using more EUS. Logistic regression models showed that abdominal pain (OR: 5.829, 95% CI 2.681–12.674, P ≤ 0.001 and alcohol abuse (OR: 3.221, CI 95%: 1.362–7.261, P: 0.002 were predictors of benign diseases. Jaundice (OR: 0.221, 95% CI: 0.084–0.58, P: 0.002, mass (OR: 0.145, 95% CI: 0.043–0.485, P: 0.008, and ductal dilation (OR: 0.297, 95% CI 0.134–0.657, P: 0.003 were associated with malignancy. Use of imaging studies, ERCP, and EUS has not decreased the percentage of benign findings after surgery for presumed pancreatic malignancy.

Intracranial developmental venous anomalies (DVAs) are considered benign vascular dispositions; they are asymptomatic in the vast majority of cases. They represent extreme variations of the venous drainage and may rarely be responsible for focal venous ischemia leading to neurological dysfunction. The aim of the study is to analyze a group of patients with symptomatic DVAs with capillary stain at angiography. We retrospectively reviewed the clinical and radiological features of patients in which a DVA was considered the cause of a neurological event. In all the patients, the DVA was suspected by angio-CT or MRI and conventional angiography was performed to detail the angioarchitecture of the DVA. A total of 7 patients and 11 DVAs were identified; three patients had multiple DVAs. Three DVAs were frontal, two were parietal, two were thalamic, one was in the midbrain, and three were cerebellar. Patients presented with progressive neurological deficits, seizures, or cerebral hemorrhage. All these DVAs were associated with a peculiar capillary stain at angiography. Although being normal anatomical variations, DVAs may create, because of hemodynamic unbalance, venous ischemia that induces angiogenic phenomena. MRI shows the suffering of the brain and angiography witnesses this angiogenesis under the form of capillary stain. Conventional angiography can thus provide useful information to recognize ''atypical'' symptomatic DVAs. (orig.)

Vertebral haemangiomas are benign lesions and often asymptomatic. They are more common in the thoracic spine where they may become symptomatic with varying presentations. We present two teenage girls who presented with progressive, nontraumatic paraparesis with no background history of chronic cough or underlying medical illness. The radiologic investigations were suggestive of vertebral haemangiomas of the thoracic spine. They had surgery: transthoracic approach with corpectomy and fusion with iliac crest autograft. The posterior stabilisation in the first patient was with Rush nails and circlage wire and only circlage wire in the second patient. The first patient's post-operative recovery was complicated by graft extrusion necessitating re-opening thoracotomy and graft replacement. They are, however, both ambulant at discharge and have remained so 13 and 15 months post-surgery. We have presented two cases with rewarding outcomes in the face of 'adaptive' instrumentation due to limited resources.

To evaluate the incidence of malignancy-mimicking sclerosed thyroid nodules, from long-term follow-up ultrasonography (US) after an US-guided percutaneous ethanol injection (PEI). We examined 86 benign cystic thyroid nodules from 80 patients. The nodules were classified into two groups based on whether an aspiration (Group A, n = 26) or non-aspiration (Group B, n 60) of infused ethanol was performed. The final follow-up US over 12 months was performed in all patients. Of the 86 nodules, the cystic portion of 82 (95.3%) cases, from 76 patients, completely disappeared subsequent to the first follow-up US (Group A, n = 24, Group B, n = 58) (Chi-square test, ρ > 0.05). Moreover, 46 sclerosed thyroid nodules showed two or more of the 'five sonographic criteria' upon a follow-up US (Group A, n = 13, 50.0%, Group B, n = 32, 53.3%). A higher ratio of the cystic portion of the nodules was associated with a higher incidence of the 'five sonographic criteria' for malignancies detected via a follow-up US (ρ < 0.01; Student's t-test). For the long-term follow-up US, the 'five sonographic criteria' were observed in half the patients who received US-guided PEI. Also, by acknowledging the possibility that sonographic findings mimic a malignancy, since the sclerosed thyroid nodule, patients may avoid an unnecessary biopsy

Objective: To evaluate the incidence, potential hazards and effective countermeasure for perforator stroke (PS) resulting from stent angioplasty of symptomatic intracranial artery stenosis. Methods: Peri-operation PS complications of 258 patients receiving Gateway balloon-Wingspan stenting for severe symptomatic intracranial stenosis were analyzed. The incidence, clinical course, and prognosis of PS resulting from stenting were recorded. Special attention was given to the anatomical features, clinical manifestation and video materials of patients with PS. χ 2 test was used for statistics. Results: Two hundred and fifty-five patients received stent angioplasty successfully and 7 patients had PS (incidence rate 2.7%). The patients with basilar artery stenosis had a higher incidence of PS resulting from intracranial stenting (6.1%, 4/66) than patients with middle cerebral artery stenosis (2.5%, 3/118) (χ 2 =2.320, P= 0.025). The potential hazards for PS included preoperative perforator stroke adjacent to the stenotic segment and prominent dissection during operation. Six patients presented symptoms after awake from general anaesthesia and one had symptoms 3 hours after stenting. One deteriorated gradually and the others reached the maximum deficit almost at once. At the follow-up of 3 months, 3 patients were disabled and scored one, two, two by mRS respectively. Conclusion: The incidence of PS resulting from intracranial stenting was low and the prognosis was not disastrous. Stenosis at basilar artery and preoperative perforator stroke adjacent to the stenotic segment were potential risk factors for PS complication. Proper maneuver of angioplasty may decrease the incidence of PS and improve the prognosis. (authors)

To perform a comprehensive literature review of the incidence, location, etiology, timing, management, and long-term sequelae of urinary tract injury in gynecologic laparoscopy for benign indication. A systematic review of PubMed, EMBASE, Cochrane Library, and ClinicalTrials.gov was conducted. Four hundred thirty-three studies were screened for inclusion with 136 full-text articles reviewed. Ninety studies published between 1975 and 2015 met inclusion criteria, representing 140,444 surgeries. Articles reporting the incidence of urinary tract injury in gynecologic laparoscopy for benign indication were included. Exclusion criteria comprised malignancy, surgery by urogynecologists, research not in English, and insufficient data. A total of 458 lower urinary tract injuries were reported with an incidence of 0.33% (95% CI 0.30-0.36). Bladder injury (0.24%, 95% CI 0.22-0.27) was overall three times more frequent than ureteral injury (0.08%, 95% CI 0.07-0.10). Laparoscopic hysterectomy not otherwise specified (1.8%, 95% CI 1.2-2.6) and laparoscopically assisted vaginal hysterectomy (1.0%, 95% CI 0.9-1.2) had the highest rates of injury. Most ureteral injuries resulted from electrosurgery (33.3%, 95% CI 24.3-45.8), whereas most bladder injuries resulted from lysis of adhesions (23.3%, 95% CI 18.7-29.0). Ureteral injuries were most often recognized postoperatively (60%, 95% CI 47-76) and were repaired by open ureteral anastomosis (47.4%, 95% CI 36.3-61.9). In contrast, bladder injuries were most often recognized intraoperatively (85%, 95% CI 75-95) and were repaired by laparoscopic suturing (34.9%, 95% CI 29.2-41.7). The incidence of lower urinary tract injury in gynecologic laparoscopy for benign indication remains low at 0.33%. Bladder injury was three times more common than ureteral injury, although ureteral injuries were more often unrecognized intraoperatively and underwent open surgical repair. These risk estimates can assist gynecologic surgeons in effectively

Gingivitis in traditional national dentistry referred to independent diseases or symptomatic condition in periodontitis and classified morphologically. The diagnostic features of the diseases are characteristic, but the clinical presentation of symptomatic gingivitis and patterns of bone destructions may vary between patients. Successful treatment of the disease depends from proper diagnosis and advanced disease stages, but for symptomatic gingivitis that accompanying chronic periodontitis, protocols include surgical excision. Despite of the high prevalence of chronic generalized periodontitis, its active treatment often start in severe destruction and bone loss (2-3 stage severity). Today etiotropic antimicrobial therapy is real way to control microbial biofilm and has solid evidence base. Applying of etiotropic antimicrobial therapy as systemic azithromycin with timely treatment of mild to moderate periodontal and bone destruction may reduce severe periodontitis incidence of and treatment-related complications in the future. This paper attempts to describe the clinical diagnostic features and the current treatment options along with a suggested protocol for comprehensive management of chronic generalized periodontitis and hypertrophic gingivitis patient with case reports and a brief review.

To examine the frequency and risk factors for symptomatic avascular necrosis (AVN) in childhood-onset systemic lupus erythematosus (cSLE). A single-center, nested, matched, case-control design was used. There were 617 patients with cSLE followed at the Hospital for Sick Children (SickKids) Lupus Clinic between July 1982 and June 2013 included in the study. The AVN cohort consisted of 37 patients identified with clinical findings of symptomatic AVN and diagnosis was confirmed by 1 or more imaging modalities. Three controls were matched to each patient with AVN by date and age at diagnosis. Baseline clinical, laboratory, and treatment characteristics were compared between patients with AVN and controls by univariable analyses and if statistically significant, were included in a multivariable logistic regression model. A total of 37/617 patients (6%) developed symptomatic AVN in 91 joints during followup at SickKids. The mean duration to disease was 2.3 years. The hip was the most commonly involved joint (26/37, 70%). Compared with the matched non-AVN cohort, patients with AVN had a higher incidence of central nervous system (CNS) involvement and nephritis, required greater cumulative prednisone (PRED) from cSLE diagnosis to AVN, received a greater maximal daily PRED dose, and had more frequent use of pulse methylprednisolone therapy. Multivariable regression analysis confirmed major organ involvement (CNS disease and/or nephritis) and maximal daily PRED dose as significant predictors of symptomatic AVN development. Patients with cSLE with severe organ involvement including nephritis and CNS disease and higher maximal daily dose of PRED are more likely to develop symptomatic AVN.

Background and aim: Rarely sarcomas develop in previous benign lesions, after a long term disease free interval. We report the experience on these rare cases observed at a single Institution. Patients and methods: 12 cases curetted and grafted, without radiotherapy developed sarcomas, between 1970 and 2005, 6.5-28 years from curettage (median 18, average 19). Age ranged from 13 to 55 years (median 30, average 32) at first diagnosis; tumors were located in the extremities (9 GCT, benign fibrous histiocytoma, ABC, and solitary bone cyst). Radiographic and clinic documentation, for the benign and malignant lesions, were available. Histology was available for 7 benign and all malignant lesions. Results: To fill cavities, autogenous bone was used in 4 cases, allograft in 2, allograft and tricalcium-phosphate/hydroxyapatite in 1, autogenous/allograft in 1, heterogenous in 1. For 3 cases the origin was not reported. Secondary sarcomas, all high grade, were 8 osteosarcoma, 3 malignant fibrous histiocytoma, and 1 fibrosarcoma. Conclusions: Recurrences with progression from benign tumors are possible, but the very long intervals here reported suggest a different cancerogenesis for these sarcomas. This condition is extremely rare accounting for only 0.26% of all malignant bone sarcomas treated in the years 1970-2005 and represents only 8.76% of all secondary bone sarcomas treated in the same years. This incidence is the same as that of sarcomas arising on fibrous dysplasia, and is lower than those arising on bone infarcts or on Paget's disease. This possible event must be considered during follow-up of benign lesions.

Acute Symptomatic Abdominal Aortic Aneurysm Secondary to Endovascular Stent Graft Associated Type II Endoleak

Directory of Open Access Journals (Sweden)

Karen Ka Leung Chan

2006-07-01

Full Text Available Endovascular abdominal aneurysm repair (EVAR is popular because of its low invasiveness and feasibility for high-risk patients. Endoleak is common after EVAR and is characterized by blood flow within the aneurysm sac but outside the stent graft. Type II or collateral endoleak commonly results from retrograde filling of the aneurysm from collateral visceral vessels, lumbar, inferior mesenteric, accessory renal or sacral arteries. Collateral leaks are generally thought to be benign and over half of the early leaks will seal spontaneously. Sporadically, collateral endoleak could lead to aneurysm sac pressurization and place the patient at ongoing risk of rupture. Herein, we report an uncommon case of early post-stent graft placement symptomatic abdominal aortic aneurysm associated with type II endoleak.

Purpose To determine the short-term and long-term adherence rates with continuous positive airway pressure (CPAP) therapy in sleep apnea patients with benign prostatic hyperplasia (BPH) compared to matched controls. Methods A case-control retrospective analysis was performed in a veterans affairs hospital. All symptomatic patients with BPH (n = 107) ever started on CPAP therapy between 2006 and 2012 were compared with controls matched for severity of sleep apnea (AHI). Adherence measures were obtained at the third and twelfth month visits. The cases included symptomatic BPH patients on active medical therapy. Diuretic use among cases and controls, and severity of nocturia among the cases were also analyzed. Results The mean AHI among cases and controls was 35.6 ± 27.3 and 35.5 ± 31 (p = 0.96). The population was male and predominantly Caucasian. There was no statistically significant difference in percent days CPAP device use ≥4 h. between symptomatic BPH patients and controls at 3-month (51.6 ± 38 vs. 47.2 ± 36; p = 0.43) and 1-year (64 ± 40.5 vs. 64.7 ± 31.3; p = 0.90) visits. The use of diuretics in the cases and controls, and the severity of nocturia in the cases did not influence adherence with CPAP therapy. Conclusions BPH or diuretic use did not affect adherence with CPAP therapy in obstructive sleep apnea. Severity of nocturia did not have any influence on adherence among the cases. BPH, regardless of the severity of nocturia, and diuretic use does not influence CPAP adherence in patients with OSA.

For 1950 - 80, 194 ovarian cancer cases were ascertained among the 70,030 females of the RERF Life Span Study (LSS-E85) sample, and 106 autopsied cases with benign ovarian neoplasms were ascertained among all 3,046 autopsies performed in the same sample. On the basis of microscopic review, 66 % of the cancer and 84 % of the benign tumor cases were classified by histological type. The age-adjusted ovarian cancer incidence rates showed a statistically significant increase with increased exposure dose, both in the entire exposed group (P 0.10). The distribution of histological types of both cancer and benign tumor of the ovary did not vary significantly with radiation dose. The data are consistent with the hypothesis that radiation injury of ovaries with secondary excess of gonadotrophic hormones are important causative factors in the development of ovarian neoplasms.

Although surrogate measures of benign prostatic hyperplasia (BPH) are often used in epidemiologic studies, their performance characteristics are unknown. Using data from the Prostate Cancer Prevention Trial (n = 5,986), we evaluated prostate-specific antigen (PSA), International Prostate Symptom Score (IPSS), and their rates of change as predictors of incident BPH. BPH (n = 842 cases) was defined as medical or surgical treatment or at least 2 IPSS of 15 or higher. Proportional hazards models were used to measure the associations of baseline PSA, IPSS, and their velocities over 2 years with BPH risk, and time-dependent receiver-operating characteristic curves were used to measure their discriminatory performance. Unit increases in PSA, IPSS, and IPSS velocity were associated with 34%, 35%, and 29% (all P specificity were both above 75%. We concluded that moderate elevations in PSA, IPSS, or their rates of change should not be used as surrogate measures of incident BPH.

To assess the diagnostic accuracy of contrast-enhanced spectral mammography (CESM), and gauge its "added value" in the symptomatic setting. A retrospective multi-reader review of 100 consecutive CESM examinations was performed. Anonymised low-energy (LE) images were reviewed and given a score for malignancy. At least 3 weeks later, the entire examination (LE and recombined images) was reviewed. Histopathology data were obtained for all cases. Differences in performance were assessed using receiver operator characteristic (ROC) analysis. Sensitivity, specificity, and lesion size (versus MRI or histopathology) differences were calculated. Seventy-three percent of cases were malignant at final histology, 27% were benign following standard triple assessment. ROC analysis showed improved overall performance of CESM over LE alone, with area under the curve of 0.93 versus 0.83 (p<0.025). CESM showed increased sensitivity (95% versus 84%, p<0.025) and specificity (81% versus 63%, p<0.025) compared to LE alone, with all five readers showing improved accuracy. Tumour size estimation at CESM was significantly more accurate than LE alone, the latter tending to undersize lesions. In 75% of cases, CESM was deemed a useful or significant aid to diagnosis. CESM provides immediately available, clinically useful information in the symptomatic clinic in patients with suspicious palpable abnormalities. Radiologist sensitivity, specificity, and size accuracy for breast cancer detection and staging are all improved using CESM as the primary mammographic investigation.

Full Text Available Background: Curettage is one of the most common treatment options for benign lytic bone tumors and tumor like lesions. The resultant defect is usually filled. We report our outcome curettage of benign bone tumors and tumor like lesions without filling the cavity. Materials and Methods: We retrospectively studied 42 patients (28 males and 14 females with benign bone tumors who had undergone curettage without grafting or filling of the defect by any other bone graft substitute. The age of the patients ranged from 14 to 66 years. The most common histological diagnosis was that of giant cell tumor followed by simple bone cyst, aneurysamal bone cyst, enchondroma, fibrous dysplasia, chondromyxoid fibroma, and chondroblastoma and giant cell reparative granuloma. Of the 15 giant cell tumors, 4 were radiographic grade 1 lesions, 8 were grade 2 and 3 grade 3. The mean maximum diameter of the cysts was 5.1 (range 1.1-9 cm cm and the mean volume of the lesions was 34.89 cm 3 (range 0.94-194.52 cm 3 . The plain radiographs of the part before and after curettage were reviewed to establish the size of the initial defect and the rate of reconstitution, filling and remodeling of the bone defect. Patients were reviewed every 3 monthly for a minimum period of 2 years. Results: Most of the bone defects completely reconstituted to a normal appearance while the rest filled partially. Two patients had preoperative and three had postoperative fractures. All the fractures healed uneventfully. Local recurrence occurred in three patients with giant cell tumor who were then reoperated. All other patients had unrestricted activities of daily living after surgery. The rate of bone reconstitution, risk of subsequent fracture or the incidence of complications was related to the size of the cyst/tumor at diagnosis. The benign cystic bone lesions with volume greater than approximately 70 cm 3 were found to have higher incidence of complications. Conclusion: This study

Benign breast disease and high breast density are prevalent, strong risk factors for breast cancer. Women with both risk factors may be at very high risk. We included 42818 women participating in the Breast Cancer Surveillance Consortium who had no prior diagnosis of breast cancer and had undergone at least one benign breast biopsy and mammogram; 1359 women developed incident breast cancer in 6.1 years of follow-up (78.1% invasive, 21.9% ductal carcinoma in situ). We calculated hazard ratios (HRs) using Cox regression analysis. The referent group was women with nonproliferative changes and average density. All P values are two-sided. Benign breast disease and breast density were independently associated with breast cancer. The combination of atypical hyperplasia and very high density was uncommon (0.6% of biopsies) but was associated with the highest risk for breast cancer (HR = 5.34; 95% confidence interval [CI] = 3.52 to 8.09, P < .001). Proliferative disease without atypia (25.6% of biopsies) was associated with elevated risk that varied little across levels of density: average (HR = 1.37; 95% CI = 1.11 to 1.69, P = .003), high (HR = 2.02; 95% CI = 1.68 to 2.44, P < .001), or very high (HR = 2.05; 95% CI = 1.54 to 2.72, P < .001). Low breast density (4.5% of biopsies) was associated with low risk (HRs <1) for all benign pathology diagnoses. Women with high breast density and proliferative benign breast disease are at very high risk for future breast cancer. Women with low breast density are at low risk, regardless of their benign pathologic diagnosis.

The Y-shaped structure of the carinal bifurcation causes difficulties in the treatment of carinal stenosis. We describe a new Y-shaped silicone stent, called the Natural Y stent. We investigated its clinical efficacy through a review of patients with benign carinal stenosis who undewent consecutive Natural Y stent placement. Between January 2004 and February 2008, 11 patients underwent ballooning, neodymium:yttrium-aluminum-garnet laser resection, or bougienation (by rigid bronchoscopy) to dilate the airway, followed by placement of the Natural Y stent. The underlying etiologies of carinal stenosis included posttuberculosis stricture in 7 patients (64%), postintubation stenosis in 2 (18%), and postoperative malacia in 2 (18%). All patients reported subjective symptomatic relief immediately after stent placement. No procedurally related deaths or immediate major complications occurred. Stent-related late complications included granulation tissue formation (64%) and mucostasis (18%, defined as > or = 50% narrowing). The median duration of overall stent placement was 439 days (range, 119 to 1729 days). The stents were successfully removed in 4 patients (36%) after a median of 409 days. The Natural Y stent provides an effective and feasible therapeutic modality in patients with benign carinal stenosis, with or without previous thoracic airway interventions.

Aim: To investigate the contribution of shear-wave elastography (SWE) in diagnosing invasive lobular breast cancer (ILC) in symptomatic patients. Materials and methods: A retrospective case-controlled study of 52 patients with ILC and 52 patients with invasive ductal cancer (IDC), matched for age and tumour size, was performed. Breast density and mammographic and greyscale ultrasound features were graded using Breast Imaging-Reporting and Data System (BI-RADS) classification by two radiologists, blinded to SWE and pathology findings. Forty-four benign lesions were also included. The sensitivity of SWE was assessed, using a cut-off value of 50 kPa for mean elasticity. Statistical significance was evaluated using Chi-square and Chi-square for trend tests. Results: Mean age for both ILC and IDC groups was 67 years. Mean size for ILC was 44 mm and IDC was 37 mm. The sensitivity for detection of ILC and IDC for mammography, greyscale ultrasound, and SWE were 79% versus 87%, 87% versus 98%, 94% versus 100%, respectively. SWE had significantly higher sensitivities than mammography for the detection of both ILC and IDC (p = 0.012 and p = 0.001, respectively). SWE was not significantly more sensitive than greyscale ultrasound for the detection of either tumour type. Four (8%) lobular cancers were benign/normal at both mammography and greyscale ultrasound, but suspicious on SWE. The incremental gain in sensitivity by using SWE in ILC was statistically significant compared to IDC (p = 0.01). Conclusion: SWE can diagnose lobular cancers that have benign/normal findings on conventional imaging as suspicious. - Highlights: • Sensitivity of shear-wave elastography (SWE) for detecting lobular cancers is 94%. • Sensitivity of SWE for detecting invasive ductal cancers is 100%. • SWE is more sensitive than mammography for detecting ductal and lobular cancers. • SWE can diagnose ILC as suspicious, which are benign/normal on conventional imaging

Clinicians use tamsulosin, an α1-adrenoceptor antagonist, to manage symptomatic benign prostatic hyperplasia (BPH). Because α1-adrenoceptors are also present in the brain, the potential exists for adverse effects on cognitive functions. We explored the association between tamsulosin use and dementia risk. We used Medicare data (2006-2012) to conduct a cohort study among patients aged ≥65 years and diagnosed with BPH. Men taking tamsulosin (n = 253 136) were matched at a 1:1 ratio using propensity-scores to each of 6 comparison cohorts: patients who used no BPH-medication (n = 180 926), and patients who used the following alternative-BPH-medications: doxazosin (n = 28 581), terazosin (n = 23 858), alfuzosin (n = 17 934), dutasteride (n = 34 027), and finasteride (n = 38 767). Assessment began following the first fill of BPH-medication to identify incident dementia by ICD-9 diagnosis codes. We estimated hazard ratios (HR) and 95% confidence intervals (CI) for dementia using Cox proportional hazard regression for each of the 6 propensity-score-matched cohort-pairs. The median follow-up period for all cohorts was 19.8 months. After propensity-score matching, the tamsulosin cohort had an incidence of dementia of 31.3/1000 person-years compared with only 25.9/1000 person-years in the no-BPH-medication cohort. The risk of dementia was significantly higher in the tamsulosin cohort, when compared with the no-BPH-medication cohort (HR [95% CI]: 1.17 [1.14, 1.21]) and each of the alternative-BPH-medication cohorts: doxazosin (1.20 [1.12, 1.28]), terazosin (1.11 [1.04, 1.19]), alfuzosin (1.12 [1.03, 1.22]), dutasteride (1.26 [1.19, 1.34]), and finasteride (1.13 [1.07, 1.19]). The significance of these findings persisted in sensitivity analyses. Tamsulosin may increase the risk of dementia in older men with BPH. Copyright © 2018 John Wiley & Sons, Ltd.

Bone matastases are one of the most common and serious conditions requiring radiotherapy, but there is still a considerable lack of agreement on optimal radiation schedule. We analyzed patients with symptomatic osseous matastases from lung (72 patients) and breast (63 patients) carcinoma treated by palliative radiotherapy between 1983 and 1992. In this series, the incidences of symptomatic bone metastases appearing within 2 years after the first diagnosis of the primary lesion were 96% and 36% for lung and breast carcinomas, respectively. Thirty percent of bone metastases from breast carcinoma were diagnosed more than 5 years after the first diagnosis. Thus careful follow-up must be carried out for a prolonged period. Pain relief was achieved at almost the same rate for bone metastases from lung and breast carcinomas (81% and 85%, respectively), an the rapid onset of pain relief (15 Gy or less) was obtained in about half the patients for both diseases. The rapid onset of pain relief and the lack of association between the onset of pain relief and primary tumor argued against the conventional theory that tumor shrinkage is a component of the initial response. In contrast to the fact that almost all lung carcinoma patients had very poor prognoses, one third of the breast carcinoma patients were alive more than 2 years after palliative radiotherapy. Thust, the late effects of radiation, such as radiation myelopathy, must be always considered especially in breast carcinoma patients even when it is 'just' palliative radiotherapy for bone metastases.

To compare the costs of photoselective vaporisation (PVP) and transurethral resection of the prostate (TURP) for management of symptomatic benign prostatic hyperplasia (BPH) from the perspective of a Queensland public hospital provider. A decision-analytic model was used to compare the costs of PVP and TURP. Cost inputs were sourced from an audit of patients undergoing PVP or TURP across three hospitals. The probability of re-intervention was obtained from secondary literature sources. Probabilistic and multi-way sensitivity analyses were used to account for uncertainty and test the impact of varying key assumptions. In the base case analysis, which included equipment, training and re-intervention costs, PVP was AU$ 739 (95% credible interval [CrI] -12 187 to 14 516) more costly per patient than TURP. The estimate was most sensitive to changes in procedural costs, fibre costs and the probability of re-intervention. Sensitivity analyses based on data from the most favourable site or excluding equipment and training costs reduced the point estimate to favour PVP (incremental cost AU$ -684, 95% CrI -8319 to 5796 and AU$ -100, 95% CrI -13 026 to 13 678, respectively). However, CrIs were wide for all analyses. In this cost minimisation analysis, there was no significant cost difference between PVP and TURP, after accounting for equipment, training and re-intervention costs. However, PVP was associated with a shorter length of stay and lower procedural costs during audit, indicating PVP potentially provides comparatively good value for money once the technology is established. © 2013 The Authors.

Background Recent evidence suggests that less than one-quarter of patients with symptomatic nosocomial Clostridium difficile infections (CDI) are linked to other in-patients. However, this evidence was limited to one geographic area. We aimed to investigate the level of symptomatic CDI transmission in hospitals located across England from 2008 to 2012. Methods A generalized additive mixed-effects Poisson model was fitted to English hospital-surveillance data. After adjusting for seasonal fluctuations and between-hospital variation in reported CDI over time, possible clustering (transmission between symptomatic in-patients) of CDI cases was identified. We hypothesised that a temporal proximity would be reflected in the degree of correlation between in-hospital CDI cases per week. This correlation was modelled through a latent autoregressive structure of order 1 (AR(1)). Findings Forty-six hospitals (33 general, seven specialist, and six teaching hospitals) located in all English regions met our criteria. In total, 12,717 CDI cases were identified; seventy-five per cent of these occurred >48 hours after admission. There were slight increases in reports during winter months. We found a low, but statistically significant, correlation between successive weekly CDI case incidences (phi = 0.029, 95%CI: 0.009–0.049). This correlation was five times stronger in a subgroup analysis restricted to teaching hospitals (phi = 0.104, 95%CI: 0.048–0.159). Conclusions The results suggest that symptomatic patient-to-patient transmission has been a source of CDI-acquisition in English hospitals in recent years, and that this might be a more important transmission route in teaching hospitals. Nonetheless, the weak correlation indicates that, in line with recent evidence, symptomatic cases might not be the primary source of nosocomial CDI in England. PMID:24932484

Frameless, surface imaging guided radiosurgery (SIG-RS) is a novel platform for stereotactic radiosurgery (SRS) wherein patient positioning is monitored in real-time through infra-red camera tracking of facial topography. Here we describe our initial clinical experience with SIG-RS for the treatment of benign neoplasms of the skull base. We identified 48 patients with benign skull base tumors consecutively treated with SIG-RS at a single institution between 2009 and 2011. Patients were diagnosed with meningioma (n = 22), vestibular schwannoma (n = 20), or nonfunctional pituitary adenoma (n = 6). Local control and treatment-related toxicity were retrospectively assessed. Median follow-up was 65 months (range 61-72 months). Prescription doses were 12-13 Gy in a single fraction (n = 18), 8 Gy × 3 fractions (n = 6), and 5 Gy × 5 fractions (n = 24). Actuarial tumor control rate at 5 years was 98%. No grade ≥3 treatment-related toxicity was observed. Grade ≤2 toxicity was associated with symptomatic lesions (p = 0.049) and single fraction treatment (p = 0.005). SIG-RS for benign skull base tumors produces clinical outcomes comparable to conventional frame-based SRS techniques while enhancing patient comfort.

Disc prolapse presenting with sciatica may be associated with enhancement of the symptomatic nerve root following magnetic resonance imaging (MRI) with intravenous gadolinium (Gd)-DTPA. Previous studies have shown, however, that this does not occur in all cases. The aim of this study was to assess the incidence of nerve root enhancement in patients with sciatica and disc prolapse and to try to identify any specific features that might be associated with the phenomenon. A total of 227 patients presenting with low back pain and/or sciatica underwent a MRI study of the lumbar spine with intravenous contrast enhancement. Nineteen of 81 (23.5 %) patients with disc prolapse demonstrated nerve root enhancement. Nerve root enhancement had a highly significant association with sequestrated disc lesions (13/19, 68 %; P < 0.0005), and was primarily seen in the symptomatic ipsilateral nerve root (16/19, 84 %). The sensitivity of nerve root enhancement associated with disc prolapse was 23.5 % with a specificity of 95.9 %, a positive predictive value of 76 % and a negative predictive value of 69.3 %. Nerve root enhancement may be indicative of the symptomatic level but its poor sensitivity negates the routine use of Gd-DTPA in MRI for sciatica. (orig.) With 4 figs., 1 tab., 37 refs.

Full Text Available Background: Benign breast tumors are common worldwide and various reports suggest an increasing incidence in Nigeria which necessitates an urgent need to differentiate it from malignant tumors. The study was carried out to classify and determine the pattern, frequency, age, and sex distribution of benign breast tumors seen in a tertiary hospital. Materials and Methods: This was a 10-year retrospective study of all benign breast tumors diagnosed at the Pathology Department of a teaching hospital from January 1 2001 to December 31 2010. Results: A total of 1566 breast tumors were diagnosed during the study period, 1035 cases of benign breast tumors constituting 66.3% of all breast tumors were seen. The female to male ratio was 72.9:1. The overall mean age for benign breast tumor was 29 years with a peak age occurrence in the third decade. Fibroadenoma (FA was the most common benign breast tumor followed by fibrocystic change and they accounted for 47.1% and 25.4% of benign breast tumors with mean age of 24.7 years and 33.4 years, respectively. FA has a peak occurrence in the third decade while fibrocystic change has a peak occurrence in the fourth decade. Other major tumors encountered were tubular adenoma (6.0%, lactating adenoma (5.6%, benign phyllodes (4.8%, sclerosing adenoma (3.3%, and blunt duct adenoma (2.5%. Gynecomastia (1.4% was the only benign breast tumor seen in males.Conclusions: Benign breast tumors are quite common, presenting mostly as FA and fibrocystic change. The tumors are seen in both sexes with a striking female preponderance and occurred predominantly in young females with a peak in the third decade. The findings are generally similar to the most previous studies from Nigeria, Africa, and the Western world with minimal variations.

a tendency of increasing incidence of the cervix uteri precancer and cancer in women of reproductive age is noticed recently being related to the growth of number of the sexually-transmitted infections. The cervix uteri pathology incidence in women of fertile age is 20-25%. to study the specific features of the cytological and colposcopical pattern in pregnant patients with benign cervix uteri pathology in the anamnesis and the character of its change post partum. we have examined 195 women during their pregnancy and 3-5 months post partum. All pregnant women, alongside with generally accepted clinical and laboratory examinations, were subjected to the simple and extended colposcopy, cytology of the targeted smears and, according to indications, the histological studies of bioptate. according to the results of the colcoscopical studies and the signs of the cervix uteri pathology found, the patients were divided into several groups. A control group included 49 pregnant women. The clinical and instrumental examination of 146 women with cervix uteri pathology has been carried out both during pregnancy and post partum. the structure of the clinical forms of benign and premalignant changes in the cervix uteri epithelium in pregnant patients has been found. Specific features of the cytological and colposcopical pattern in pregnant patients with benign cervix uteri pathology in anamnesis have been studied. The relationship between the parity of pregnancy, delivery, route of delivery and regress of both benign and premalignant changes in the cervix uteri epithelium 3-5 months post partum has been determined.

Aim of this study was to evaluate the sensitivity of virtual colonoscopy (CT colonography) in the identification of colorectal cancer and to define the limitations and the advantages of this imaging modality, as well as indications to the examination. It was examined prospectively 62 symptomatic patients aged 36 to 82 years (28 women and 34 men). All patients underwent both conventional and virtual colonoscopy on the same day; the conventional examination allowed exploration of the entire colon. Conventional colonoscopy identified 89 lesions 3-50 mm in diameter, namely 84 benign and 5 malignant lesions. No lesions were identified in 12 patients. CT colonography identified 52 of the 89 lesions, with 57.1% diagnostic accuracy. They were 11 false positives (82.5% positive predictive value and 52.2% specificity) and 37 false negatives (24.5% negative predictive value and 58.4% sensitivity). Sensitivity was significantly higher (85.7%) for polyps ≥ 1 cm. Virtual colonoscopy is an imaging modality with good diagnostic yield, well tolerated by patients and with great potentials for further development. It was suggested that the examination be performed in symptomatic patients who cannot undergo total colonoscopy or refuse the other imaging modalities. Further studies are waranted in larger series of patients, possibly introducing it in screening programs [it

Purpose To compare long-term outcome in a population-based group of children with cryptogenic vs symptomatic focal epilepsy diagnosed from 1980–2004 and to define the course of epilepsy in the cryptogenic group. Methods We identified all children residing in Olmsted County, MN, 1 month through 17 years with newly diagnosed, non-idiopathic focal epilepsy from 1980–2004. Children with idiopathic partial epilepsy syndromes were excluded. Medical records were reviewed to determine etiology, results of imaging and EEG studies, treatments used, and long-term outcome. Children were defined as having symptomatic epilepsy if they had a known genetic or structural/metabolic etiology, and as cryptogenic if they did not. Key Findings Of 359 children with newly-diagnosed epilepsy, 215 (60%) had non-idiopathic focal epilepsy. Of these, 206 (96%) were followed for more than 12 months. Ninety five children (46%) were classified as symptomatic. Median follow-up from diagnosis was similar in both groups, being 157 months (25%ile, 75%ile 89, 233) in the cryptogenic group vs 134 months (25%ile, 75%ile 78, 220) in the symptomatic group (p=0.26). Of 111 cryptogenic cases, 66% had normal cognition. Long-term outcome was significantly better in those with cryptogenic vs symptomatic etiology (intractable epilepsy at last follow-up, 7% vs 40%, p<0.001; seizure-freedom at last follow-up, 81% vs 55%, p<0.001). Of those who achieved seizure-freedom at final follow-up, 68% of the cryptogenic group versus only 46% of the symptomatic group were off antiepileptic medications (p=0.01). One third of the cryptogenic group had a remarkably benign disorder, with no seizures seen after initiation of medication, or in those who were untreated, after the second afebrile seizure. A further 5% had seizures within the first year but remained seizure-free thereafter. With the exception of perinatal complications, which predicted against seizure remission, no other factors were found to significantly

Benign prostatic hyperplasia (BPH) is a frequent cause of lower urinary symptoms, with a prevalence of 50% by the sixth decade of life. Hyperplasia of stromal and epithelial prostatic elements that surround the urethra cause lower urinary tract symptoms (LUTS), urinary tract infection and acute urinary retention. Medical treatments of symptomatic BPH include; 1) the 5α-reductase inhibitors, 2) the α1-adrenergic antagonists, and 3) the combination of a 5α-reductase inhibitor and a α1-adrenergic antagonist. Selective α1-adrenergic antagonists relax the smooth muscle of the prostate and bladder neck without affecting the detrussor muscle of the bladder wall, thus decreasing the resistance to urine flow without compromising bladder contractility. Clinical trials have shown that α1-adrenergic antagonists decrease LUTS and increase urinary flow rates in men with symptomatic BPH, but do not reduce the long-term risk of urinary retention or need for surgical intervention. Inhibitors of 5α-reductase decrease production of dihydrotestosterone within the prostate resulting in decreased prostate volumes, increased peak urinary flow rates, improvement of symptoms, and decreased risk of acute urinary retention and need for surgical intervention. Interim results of the ongoing Combination of Avodart and Tamsulosin (CombAt) study have shown combination therapy with the 5α-reductase inhibitor dutasteride and the α1-adrenergic antagonist tamsulosin offer significant improvements from baseline compared with either drug alone.

Background Extremely few objective estimates of traumatic brain injury incidence include all ages, both sexes, all injury mechanisms, and the full spectrum from very mild to fatal events. Methods We used unique Rochester Epidemiology Project medical records-linkage resources, including highly sensitive and specific diagnostic coding, to identify all Olmsted County, MN, residents with diagnoses suggestive of traumatic brain injury regardless of age, setting, insurance, or injury mechanism. Provider-linked medical records for a 16% random sample were reviewed for confirmation as definite, probable, possible (symptomatic), or no traumatic brain injury. We estimated incidence per 100,000 person-years for 1987–2000 and compared these record-review rates with rates obtained using Centers for Disease Control and Prevention (CDC) data-systems approach. For the latter, we identified all Olmsted County residents with any CDC-specified diagnosis codes recorded on hospital/emergency department administrative claims or death certificates 1987–2000. Results Of sampled individuals, 1257 met record-review criteria for incident traumatic brain injury; 56% were ages 16–64 years, 56% were male, 53% were symptomatic. Mechanism, sex, and diagnostic certainty differed by age. The incidence rate per 100,000 person-years was 558 (95% confidence interval = 528–590) versus 341 (331–350) using the CDC data system approach. The CDC approach captured only 40% of record-review cases. Seventy-four percent of missing cases presented to hospital/emergency department; none had CDC-specified codes assigned on hospital/emergency department administrative claims or death certificates; 66% were symptomatic. Conclusions Capture of symptomatic traumatic brain injuries requires a wider range of diagnosis codes, plus sampling strategies to avoid high rates of false-positive events. PMID:21968774

This study aims to estimate the prostate-specific antigen density (PSAD) cutoff level for detecting prostate cancer (CAP) in Nigerian men with "grey zone PSA" (4-10 ng/ml) and normal digital rectal examination findings. We addressed this research question: Is the international PSAD cutoff of 0.15 ideal for detecting CAP in our symptomatic patients with "grey zone PSA?" To estimate the prostate-specific antigen density (PSAD) cutoff level for detecting CAP in Nigerian men with "grey zone PSA" (4-10 ng/ml) and normal digital rectal examination findings. Prospective. A tertiary medical center in Enugu, Nigeria. Two hundred and fifty-four men with either benign prostatic hyperplasia (BPH) or CAP were recruited. Patients with PSA above 4 ng/ml or abnormal digital rectal examination or hypoechoic lesion in the prostate were biopsied. PSAD and histology report of BPH or CAP. Ninety-seven patients had CAP while 157 had benign prostatic hyperplasia (BPH). Seventy-two patients had their serum PSA value within the range of 4.0 and 10 ng/ml. PSAD cutoff level to detect CAP was 0.04 (sensitivity 95.88 %; specificity 28.7 %). The PSAD cutoff level generated for Nigerian men in this study is 0.04 which is relatively different from international consensus. This PSAD cutoff level has a positive correlation with histology and could detect patients with CAP who have "grey zone PSA."

Surgery is the treatment of choice for symptomatic tracheal obstruction due to benign or malignant thyroid disease. In case of inoperability, or when surgery is refused, few therapeutic alternatives are available. Interventional bronchoscopic procedures have only been reported anecdotally. The objective of this study is to evaluate the results of interventional bronchoscopic procedures in the treatment of severe tracheal obstruction due to thyroid disease. Retrospective cohort analysis. University hospital, tertiary referral center. Thirty consecutive patients referred for bronchoscopic treatment of benign (n = 17) or malignant (n = 13) thyroid-related upper airway obstruction due to tracheomalacia, extrinsic compression, and/or tracheal ingrowth. Indications for bronchoscopic treatment were medical or surgical inoperability, prevention or treatment of tracheomalacia, and refusal of surgery. There were no procedure-related complications. Rigid bronchoscopy with dilatation, stenting and/or Nd-YAG laser treatment, and clinical follow-up. Subjective improvement, pulmonary function tests, early and late complications, and survival. In the benign group, immediate (100% relief of dyspnea) and long-term (88% relief of dyspnea) results were excellent after airway stenting (21 stents used in 17 patients). There was one unrelated death 1 week after stenting in a 98-year-old patient. There were 6% and 30% short-term and long-term complications, respectively, that could be managed endoscopically. In the malignant group, Nd-YAG laser treatment (n = 3) and stenting (n = 13) yielded immediate and long-term success in 92% of patients. There were 15% short-term and 8% long-term complications. Median survival time was 540 days. Interventional bronchoscopic procedures including Nd-YAG laser treatment and stenting are valuable alternatives to surgery in inoperable thyroid-induced tracheal obstruction, or when surgery is refused.

Objective: To find the incidence of malignancy in females presenting with breast lumps in surgical out patient and to find out the age related incidence of benign and malignant diseases in these patients. Patients and Methods: All cases reporting to surgical outdoor with breast lumps were included and underwent investigation for the breast lumps to determine the histopathological diagnosis. Results: A total of 277 cases were studied. 24.2% breast lumps were malignant and 75.8% were benign. The incidence of malignancy increases from 0% in 2nd decade to 38.9% in 5th and 100% in 9th decade of life. The probability of diagnosing a breast lump as a malignant is one in three in 4th decade, two in five in 5th decade and more than one in two there after. Fibrocystic disease (33.8%) and Fibro adenoma (27.1%) was the commonest finding among the benign lumps. Among malignant lumps infiltrating duct carcinoma (68.7%) is the commonest finding. Conclusion: There is a significantly high incidence of malignant breast lumps after the 3rd decade of life and it increases subsequently. It is recommended that the surgeon managing a case of breast lump in a patient above 30 years should be highly suspicious and cautious so that early detection and management of malignant lumps be carried out.

PurposeTo summarize current evidence on outcomes and complications of prostatic artery embolization as a treatment for patients with lower urinary tract symptoms secondary to benign prostatic hyperplasia.Methods and MaterialsA database search of MEDLINE, Embase, Web of Science, and Cochrane Library was performed for published literature up to August 2015 concerning PAE in the treatment of BPH. Inclusion and exclusion criteria were applied by two independent reviewers, and disagreements were resolved by consensus. Peer-reviewed studies concerning PAE with BPH with a sample size >10 and at least one measured parameter were included.ResultsThe search yielded 193 articles, of which ten studies representing 788 patients, with a mean age of 66.97 years, were included. Patients had LUTS ranging from moderate to severe. At 6 months following procedure, PV, PVR, Qmax, IPSS, and QoL were significantly improved (P < 0.05), while for PSA there was no significant change. At 12 and 24 months, PV, PSA, PVR, Qmax, IPSS, and QoL were significantly improved (P < 0.05). IIEF was unchanged at 6 and 12 months but was significantly reduced at 24 months.ConclusionThis suggests that PAE is effective in treating LUTS in the short and intermediate term.

To find vertebral metastases with high risk of symptomatic malignant spinal cord compression (MSCC), features of vertebral metastases caused motor deficits of the lower extremities were examined. From 2004 through 2006, 78 patients with metastases of the thoracic and/or the cervical spine were treated with radiation therapy (RT). Of these, 86 irradiated lesions in 73 patients were evaluable by magnetic resonance imaging and/or computed tomography at the initiation of RT and were reviewed retrospectively in this study. Twenty-eight patients (38%) had motor deficits at the initiation of RT. Assessed factors were age, sex, primary disease (lung, breast, digestive system and other cancer), lamina involvement, main level of tumor location and vertebral-body involvement. Incidence of motor deficits at the initiation of RT was 55% for lesions with lamina involvement and 5% for lesions without lamina involvement (P 0.9999, P=0.7798, P=0.1702 and P=0.366, respectively). Vertebral metastases with lamina involvement tended to cause symptomatic MSCC. Latent development of MSCC occurred more frequently in the MTS compared with other levels of the thoracic and the cervical spine. (author)

Although stereotactic ablative body radiotherapy (SABR) is widely used therapeutic technique, predictive factors of radiation pneumonitis (RP) after SABR remain undefined. We aimed to investigate the predictive factors affecting RP in patients with primary or metastatic lung tumors who received SABR. From 2012 to 2015, we reviewed 59 patients with 72 primary or metastatic lung tumors treated with SABR, and performed analyses of clinical and dosimetric variables related to symptomatic RP. SABR was delivered as 45–60 Gy in 3–4 fractions, which were over 100 Gy in BED when the α/β value was assumed to be 10. Tumor volume and other various dose volume factors were analyzed using median value as a cutoff value. RP was graded per the Common Terminology Criteria for Adverse Events v4.03. At the median follow-up period of 11 months, symptomatic RP was observed in 13 lesions (12 patients, 18.1%), including grade 2 RP in 11 lesions and grade 3 in 2 lesions. Patients with planning target volume (PTV) of ≤14.35 mL had significantly lower rates of symptomatic RP when compared to others (8.6% vs. 27%; p = 0.048). Rates of symptomatic RP in patients with internal gross tumor volume (iGTV) >4.21 mL were higher than with ≤4.21 mL (29.7% vs. 6.1%; p = 0.017). The incidence of symptomatic RP following treatment with SABR was acceptable with grade 2 RP being observed in most patients. iGTV over 4.21 mL and PTV of over 14.35 mL were significant predictive factors related to symptomatic RP.

Objective: To assess the safety, feasibility, short- and mid-term efficacy of wingspan stent for treating patients with symptomatic intracranial artery stenosis. Methods: A total of 113 patients with severe symptomatic intracranial stenosis were enrolled and Gateway-wingspan stenting were performed on all patients. The technical success, the pre- and post-stenting stenosis, perioperative complications, clinical outcome and restenosis rates were recorded, and chi-square test was used for analysis of complication rate by comparing our results with the results of Warfarin-Aspirin Symptomatic Intracranial Disease (WASID) study and NIH multi-center Wingspan stenting trial. Results: The technical success rate was 99.1% (112/ 113). The mean pre and post-stent stenoses were (80.7±9.3)% and (27.7±9.7)% (χ 2 =9.397, P<0.05). The total complication rate was 4.4% (5/113) during the follow-up (mean 14.5 months, range 1-28 months), and the frequency of' restenosis was 12.5% (5/40) at 6 months. The primary endpoint events, ischemic stroke, and lesion-related ischemic stroke were lower in our study (4.5%, 3.5%, 3.5%) compared with the results of WASID trial (21.1%, 20.4%, 15.0%, P<0.05). For those with poor outcome in the three high-risk sub-groups which were with more than 70% stenosis, or last event from the treatment was less than 17 days, or NIHSS was above 1, a better outcome was observed in our group (4.5%, 4.7% and 2.0% in our study, 19.0%, 17.0% and 19.6% in previous study, P<0.05). The medium-term efficacy in this group (4.5%) significantly improved compared with NIH study (14.0%, P< 0.05). Conclusions: Wingspan stenting for symptomatic intracranial arterial stenosis is with good safety, feasibility and low perioperative stroke rate and mortality. The incidence of primary endpoint events and the ischemic events are lower than those of medication group, and the efficacy of stenting is significantly better than medication even in high-risk population.

Shear wave elastography (SWE) is a promising adjunct to greyscale ultrasound in differentiating benign from malignant breast masses. The purpose of this study was to characterise breast cancers which are not stiff on quantitative SWE, to elucidate potential sources of error in clinical application of SWE to evaluation of breast masses. Three hundred and two consecutive patients examined by SWE who underwent immediate surgery for breast cancer were included. Characteristics of 280 lesions with suspicious SWE values (mean stiffness >50 kPa) were compared with 22 lesions with benign SWE values (masses were more often soft on SWE than masses representing invasive breast cancer. Invasive cancers that were soft were more frequently: histological grade 1, tubular subtype, ≤10 mm invasive size and detected at screening mammography. No significant differences were found with respect to the presence of invasive lobular cancer, vascular invasion, hormone and HER-2 receptor status. Lymph node positivity was less common in soft cancers. Malignant breast masses classified as benign by quantitative SWE tend to have better prognostic features than those correctly classified as malignant. • Over 90 % of cancers assessable with ultrasound have a mean stiffness >50 kPa. • 'Soft' invasive cancers are frequently small (≤10 mm), low grade and screen-detected. • Pure DCIS masses are more often soft than invasive cancers (>40 %). • Large symptomatic masses are better evaluated with SWE than small clinically occult lesions. • When assessing small lesions, 'softness' should not raise the threshold for biopsy.

There is little information in the literature concerning the role of bone scanning in benign bone neoplasms except for sporadic reports. Since the advent of /sup 99m/Tc-polyphosphate, bone imaging has proven feasible and useful in locating the cause of bone pain, such as in osteoid osteomas, which are not always radiologically apparent, and in evaluating whether or not a radiologic lesion is indeed benign and solitary. Blood-pool images are particularly important in neoplastic disease, since the absence of hyperemia in the immediate postinjection period favors the diagnosis of a benign neoplasm, as does low-grade uptake on the delayed study. The scan, including pinhole magnification images, is especially valuable in diagnosing lesions in the spine and pelvis, which are poorly seen radiologically. We have studied various types of benign bone tumors, including simple and aneurysmal bone cysts, fibrous cortical defects, and nonossifying fibromas, all of which had minimal or no increased uptake of the radiopharmaceutical, unless traumatized. Although osteochondromas and enchondromas showed varied accumulation of activity, the scan was useful in differentiating these from sarcomatous lesions. All osteoid osteomas demonstrated marked activity, and could be accurately located preoperatively, as could the extent of fibrous dysplasia. The bone scan in the reticuloses also showed abnormal accumulation of activity, and aided in arriving at the prognosis and treatment of histiocytic bone lesions

Benign fibrous histiocytoma is an extremely rare spinal tumor with ten reported cases in the literature. Benign fibrous histiocytoma constitutes a diagnostic challenge because it shares common clinical symptoms, radiological characteristics, and histological features with other benign lesions involving the spine. We present a case of benign fibrous histiocytoma of the lumbar spine and discuss its differential diagnosis and management. (orig.)

Pathological features of benign prostatic hyperplasia (BPH) dictate various responses to prostatic artery embolization (PAE). Typically, BPH originates in the transition zone and periurethral region, where should be considered the primary target area in PAE procedures. Given that histological heterogeneity of components in hyperplasia nodules, epithelial or stromal, identifying the more responsive nodules to PAE will have clinical implications. Since some lower urinary tract symptoms (LUTS) in patients with BPH are usually related to bladder outlet obstruction-induced changes in bladder function rather than to outflow obstruction directly, proper selection of candidate patients prior to PAE is of great clinical importance. BPH is a typical chronic progressive condition, suggesting PAE could aim not only to relieve LUTS but also to delay or prevent the clinical progression. Awareness of the pathological background of BPH is essential for interventional radiologists to improve clinical outcomes and develop new treatment strategies in clinical practice of PAE

Pancreatico-enteric anastomotic (PEA) stenosis is one of the late complications following pancreaticoduodenectomy (PD) and reported for benign diseases. Literature for PEA stenosis following PD for malignancy is very limited due to low survival. Patients undergoing surgery for symptomatic, recurrent, obstructive pancreatitis due to PEA stenosis following PD for malignancy were retrospectively identified from the authors' prospective database between January 1997 and December 2014. Six patients with median age 56.5 years underwent revision surgery for PEA stenosis during this time period. At primary PD, all were node negative with T1/T2 disease. The primary PEA were pancreatico-jejunostomy (PJ) (n = 5) and pancreatico-gastrostomy (n = 1). Median time to develop symptoms was 62 months. At revision surgery, a Roux-en-Y longitudinal PJ (n = 5) and an end-to-side PJ (n = 1) were done. With a median follow-up of 36 months, pain relief was excellent (n = 5) to average (n = 1). With improving long-term survival in patients undergoing PD for malignancy more such patients will be identified in future. Patients with symptomatic PEA stenosis following PD for malignancy can be managed surgically, with excellent outcomes in centers of expertise in pancreatic surgery.

Symptomatic spondylolysis resulting from a stress fracture of the pars interarticularis is a cause of low back pain in the juvenile and adolescent patient. Treatment is conservative in the majority of cases. To analyze the outcome of patients with symptomatic isthmic spondylolysis treated nonoperatively with a custom fit thoracolumbar orthosis and activity cessation for 3 months followed by an organized physical therapy program. Retrospective case series. Four hundred thirty-six juvenile and adolescent patients with spondylolysis. Pain improvement, hamstring flexibility, range of motion, resolution of back spasms, and return to previous activities. Retrospective review of 436 juvenile and adolescent patients with symptomatic spondylolysis confirmed by single-photon emission computed tomography or computed tomography. Clinical outcomes were assessed through patient history and physical examination. Ninety-five percent of patients achieved excellent results according to a modified Odom's Criteria. The remaining 5% of patients achieved good results as they required occasional nonsteroidal anti-inflammatory drugs to relieve pain. Back spasms were resolved and hamstring tightness and range of motion returned to normal in all patients. All patients returned to their preinjury activity level. No patients went on to surgery. Symptomatic juvenile and adolescent patients with an isthmus spondylolysis may be effectively managed with a custom fit thoracolumbar orthosis brace and activity cessation for approximately 3 months followed by an organized physical therapy program.

Cognitive bias in symptomatic and recovered agoraphobics.

Stoler, L S; McNally, R J

1991-01-01

Symptomatic agoraphobics, recovered agoraphobics, and normal control subjects completed a series of sentence stems that had either ambiguous or unambiguous meanings, and had either a potentially threatening or a nonthreatening connotation. The written completions made by subjects to these stems were classified as indicating either a biased (i.e. threat-related) or unbiased interpretation of the meaning of the stem, and if a biased interpretation was made, whether the subject indicated efforts at adaptive coping with the perceived threat. Results indicated that symptomatic agoraphobics exhibited strong biases for interpreting information as threatening, relative to normal control subjects. Moreover, recovered agoraphobics resembled symptomatic agoraphobics more than normal control subjects, thus indicating that cognitive biases may persist following cessation of panic attacks and reductions in avoidance behavior. However, recovered agoraphobics also exhibited tendencies to cope adaptively with perceived threats whereas symptomatic agoraphobics did not.

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.

To evaluate the efficacy of a collagen-fibrin patch for the prevention of symptomatic lymphoceles after pelvic lymphadenectomy in women with gynecologic malignancies. In a multicenter, randomized, clinical trial, 164 women with pelvic lymphadenectomy were allocated either to bilateral pelvic application of two collagen-fibrin patches or no intervention. Main outcome was efficacy, defined as reduction of symptomatic lymphocele rate diagnosed within four weeks after surgery. Secondary outcomes were asymptomatic lymphoceles and subsequent interventions. Sample size was based on the assumption that application of a collagen-fibrin patch reduces the prevalence of symptomatic lymphoceles by at least 66%. The study was single-blinded, i.e., patients and primary outcome assessors, but not surgeons, were blinded to the treatment allocation. A total of 75 women were randomized to the intervention and 89 to the control group. All women received the allocated intervention. In total, 42 (27.4%) lymphoceles and 8 (5.2%) symptomatic lymphoceles were observed. Symptomatic lymphoceles were observed in 5/68 (7.4%) women in the intervention group and 3/85 (3.5%) women in the control group (p = 0.47). Asymptomatic lymphoceles were observed in 16 (23.5%) women in the intervention group compared to 18 (21.2%) in the control group (p = 0.85). In a multivariate logistic regression model, no independent risk factor for the development of a symptomatic lymphocele was ascertained. Intraoperative application of collagen-fibrin patches to the pelvic side walls does not reduce the incidence of symptomatic lymphoceles in women with gynecologic malignancies undergoing pelvic lymphadenectomy.

after surgical intervention; it is not effective for intracranial tumors with symptomatic mass effect. The radiobiological effects of stereotactic radiosurgery on the benign tumors are mainly caused by cellular and vascular mechanisms. Among the patients in this study, high-dose irradiation did not increase tumor proliferation. GKS can induce primary and secondary effects in tumors, which could last more than 10 years, thereby warranting long-term follow-up after GKS.

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

Objective. To demonstrate the value of MR imaging in the diagnosis and differentiation of the various symptomatic complications of osteochondromas, providing pathological correlation with emphasis on the usefulness of MR imaging as a single imaging modality in these patients. Design. We retrospectively reviewed all MR examinations of clinically symptomatic osteochondromas (30 patients) performed at our institution between March 1990 and October 1997. Patients. Thirty patients had clinically symptomatic osteochondromas during the study period. Twenty patients were male and 10 were female. There were five cases of multiple osteochondromatosis. Pathological correlation was available in 24 patients. Results and conclusion. Symptomatic complications included fracture (7%), osseous deformity limiting range of motion (23%), vascular injury (7%), neurological compromise (10%), bursa formation (27%) and malignant transformation (27%). MR imaging was able to diagnose or suggest the etiology for the clinical symptomatology in all cases, demonstrating that it is an ideal imaging modality in the diagnostic evaluation of symptomatic complications of osteochondromas and often avoids the need for further imaging.

Symptomatic unruptured cerebral aneurysms. Features and surgical outcome

International Nuclear Information System (INIS)

Date, Isao

2010-01-01

Development of less invasive imaging studies, such as magnetic resonance angiography, has increased the chances that unruptured cerebral aneurysms are found. The rupture risk of 'symptomatic' aneurysms is higher than for 'asymptomatic' aneurysms; so 'symptomatic' aneurysms are more often surgically treated. Many reviews examine 'asymptomatic' unruptured cerebral aneurysms, but few evaluate 'symptomatic' aneurysms. The author has treated many patients with symptomatic unruptured cerebral aneurysms and found that improved cranial nerve signs can be expected if the surgical treatment is performed before the symptoms become irreversible; the critical period is approximately 3 months. It is important to suppress the pulsation of the aneurysms compressing the cranial nerves; both a clipping procedure and endovascular coiling are effective. Cranial nerve signs are more commonly the symptoms of unruptured cerebral aneurysms, but large to giant aneurysms can also be the causes of hemiparesis, hydrocephalus, epilepsy, or even cerebral infarction. This review summarizes the features and surgical outcome of symptomatic unruptured cerebral aneurysms. (author)

Full Text Available Joe Miller, Thomas H TarterDivision of Urology, Southern Illinois University School of Medicine, Springfield, IL, USAAbstract: Benign prostatic hyperplasia (BPH is a frequent cause of lower urinary symptoms, with a prevalence of 50% by the sixth decade of life. Hyperplasia of stromal and epithelial prostatic elements that surround the urethra cause lower urinary tract symptoms (LUTS, urinary tract infection, and acute urinary retention. Medical treatments of symptomatic BPH include; 1 the 5α-reductase inhibitors, 2 the α1-adrenergic antagonists, and 3 the combination of a 5α-reductase inhibitor and a α1-adrenergic antagonist. Selective α1-adrenergic antagonists relax the smooth muscle of the prostate and bladder neck without affecting the detrussor muscle of the bladder wall, thus decreasing the resistance to urine flow without compromising bladder contractility. Clinical trials have shown that α1-adrenergic antagonists decrease LUTS and increase urinary flow rates in men with symptomatic BPH, but do not reduce the long-term risk of urinary retention or need for surgical intervention. Inhibitors of 5α-reductase decrease production of dihydrotestosterone within the prostate resulting in decreased prostate volumes, increased peak urinary flow rates, improvement of symptoms, and decreased risk of acute urinary retention and need for surgical intervention. The combination of a 5α-reductase inhibitor and a α1-adrenergic antagonist reduces the clinical progression of BPH over either class of drug alone.Keywords: prostatic hyperplasia, 5α-reductase, dutasteride

Previous studies suggested that menopausal transition played an important role in the clinical course of major depression and bipolar disorder. However, the role of symptomatic menopausal transition in diagnostic conversion from major depression to bipolar disorder was still unknown. Using the Taiwan National Health Insurance Research Database, 50,273 midlife women aged between 40 and 60 years in 2002∼2008 with major depression were enrolled in our study and divided into two subgroups based on the presence (n = 21,120) or absence (n = 29,153) of symptomatic menopausal transition. Subjects who had subsequent bipolar disorder during the follow-up were identified. Midlife women with major depression and symptomatic menopausal transition had a higher incidence of the diagnostic conversion to bipolar disorder (7.3 vs. 6.6%, p = 0.003) than those with major depression alone. Cox regression analysis after adjusting for demographic data and psychiatric comorbidities further showed that symptomatic menopausal transition was associated with an increased risk of developing bipolar disorder (HR 1.14, 95% CI 1.07∼1.23) among midlife women with major depression. Sensitivity test after excluding the 1-year and 3-year observation exhibited the consistent findings (HR 1.18, 95% CI 1.09∼1.28; HR 1.20, 95% CI 1.08∼1.34). Midlife women with the dual diagnoses of major depression and symptomatic menopausal transition had an increased risk of the diagnostic conversion to bipolar disorder compared to those with major depression alone. Further studies may be required to investigate the underlying mechanisms among menopausal transition and the diagnostic conversion from major depression to bipolar disorder.

To summarize the updated DEGRO consensus S2e guideline recommendations for the treatment of benign symptomatic functional disorders with low-dose radiotherapy. This overview reports on the role of low-dose radiotherapy in the treatment of functional disorders in cases of heterotopic ossification (HO) and Graves orbitopathy (GO). The most relevant aspects of the DEGRO S2e Consensus Guideline ''Radiation Therapy of Benign Diseases 2014'' regarding diagnostics, treatment decision, dose prescription, as well as performance of radiotherapy and results are summarized. For both indications (HO, GO), retrospective and some prospective analyses have shown remarkable effects in terms of symptom relief. Nevertheless, the level of evidence (LoE) and the grade of recommendation (GR) vary: LoE 1-2 and GR A-B (HO), LoE 2 and GR B (GO). Low-dose radiotherapy for benign symptomatic functional disorders has proven to be effective, according to different authors, for 25-100 % of the patients studied and therefore it may be a reasonable prophylactic and therapeutic option if noninvasive or invasive methods have been used without persistent success. For HO, a single-fraction dose of 7-8 Gy or fractionated radiation with five fractions of 3.5 Gy is recommended. For GO, single-fraction doses of 0.3-2.0 Gy, and total doses of 2.4-20 Gy/series, applied in one daily fraction are recommended. (orig.)

Purpose The aim of this study was to evaluate the decrease of benign thyroid nodules after bipolar radiofrequency ablation (RFA) in a 3-month follow-up using a multiple overlapping shot technique ('MOST'). Methods A total of 18 patients with 20 symptomatic benign thyroid nodules (17 cold nodules, 3 hyperfunctioning nodules) were treated in one single session by bipolar RFA. Bipolar ablation was performed using MOST. The nodule volumes were measured prior to ablation and 3 months after the procedure using ultrasound. The population consisted of either solid (>80% solid tissue within the volume of interest), complex, or cystic nodules (nodule volume (ΔV), median 5.3 mL (range 0.13-43.1 mL), corresponding to a relative reduction in mean of 56 ± 17.9%. Median initial volume was 8 mL (range 0.48-62 mL); 3 months after ablation a median volume of 2.3 mL (range 0.3-32 mL) was measured. Nodule growth ≥50% occurred in 70% (14 nodules). At the follow-up no complications such as infections, persisting pain, nerve injuries or immunogen stimulation occurred. Patients with cold nodules (15) remained euthyroid, with hyperfunctioning nodules either euthyroid (2) or latent hypofunctional (1). Conclusion The use of bipolar RFA is an effective, safe and suitable thermoablative technique to treat benign thyroid nodules. Combined with the multiple overlapping shot technique it allows sufficient ablation.

Bactibilia has several consequences to human health. Assessing the bile microbiology of patients with biliopancreatic diseases in order to identify bacteria and their possible infectious complications. Retrospective study of 30 bile culture samples from patients with benign and malignant biliopancreatic diseases. The samples were assessed to set the bile microbiological flora and to search for its possible link with comorbidity, carcinogenesis and postoperative infectious complications. Thirty bile samples from patients at mean age ≈57.7 years, mostly female (n=18), were assessed. Bactibilia was found in 12 cases, mostly in patients with benign diseases (n=8), older than 50 years (n=23) and female (n=10). Adenocarcinoma of the duodenal papilla (n=9) and cholelithiasis (n=8) were the most common diseases. Escherichia coli (n=5) and Klebsiella sp (n=3) were predominantly found in patients with benign diseases; and Klebsiella sp (n=2) and Streptococcus sp (n=2) were prevalent in cancer patients. There were postoperative infectious complications in seven cases, five of them in bactibilia-associated patients (P=0.084). Bactibilia was found in 12 samples and Escherichia coli and Klebsiella sp were most often identified in patients with benign diseases, as well as Streptococcus sp and Klebsiella sp in cancer patients. There was a trend of higher postoperative infectious complication incidence in patients with bactibilia.

Case Experience of Radiofrequency Ablation for Benign Thyroid Nodules: From an Ex Vivo Animal Study to an Initial Ablation in Taiwan

Full Text Available Radiofrequency ablation (RFA is a minimally invasive technique, used with ultrasound or computed tomography guidance, which can produce tissue coagulation necrosis in various kinds of tumors in the human body. In the past 10 years, numerous studies about RFA in benign thyroid nodules have been published. Reviewing these studies, we noticed that the effectiveness of ablation was higher when it was performed with the “moving-shot technique” via an internally cooled electrode. A consensus statement published from the Korean Society of Radiology also suggested the moving-shot technique as a standard ablation procedure for benign thyroid nodule ablation in Korea. In Taiwan, most symptomatic benign nodules are currently treated with surgical removal. RFA for mass lesions is primarily performed for the treatment of metastatic hepatic tumors. In our case, we have attempted to introduce RFA for benign thyroid nodules in Taiwan. Because endocrinologists in Taiwan were not familiar with this technique, we adopted a stepwise approach in learning how to perform RFA. We conducted ex vivo animal ablation exercises to gain experience in setting the radiofrequency generator for the right ablation mode and appropriate power output. The thyroid nodule volume reduction rate after 1 year of follow up was approximately 50% in this case. The most important thing we learned from this trial is that we confirmed the safety of thyroid nodule ablation. To the best of our knowledge, this is the first reported study of RFA of a thyroid nodule in Taiwan.

To analysis the causes of benign tracheal stenosis and evaluate the curative effect of intraluminal bronchoscopic treatment. 158 patients with benign tracheal stenosis in our hospital from September 2005 to September 2012 were collected to retrospectively analysis the causes and clinic features of tracheal stenosis. Interventional treatments through bronchoscopy were used to treat the benign tracheal stenosis and the curative effects were evaluated. 158 cases of benign tracheal stenosis were recruited to our study, 69.6% of them were young and middle-aged. The main causes of benign tracheal stenosis were as follows: secondary to postintubation or tracheotomy in 61.4% (97/158), tuberculosis in 16% (26/158), benign tumor in 5.1% (8/158) and other 27 cases. 94.3% patients improved in symptoms with alleviation immediately after bronchoscopic treatment, the average tracheal diameter increased form (4.22 ± 2.06) mm to (10.16 ± 2.99) mm (t = 21.48, P benign tracheal stenosis were increasing year by year. The most common cause of benign tracheal stenosis was postintubation and tracheotomy. Interventional treatments through bronchoscopy is effective in treating benign tracheal stenosis, but repeated interventional procedures may be required to maintain the favorable long-term effects.

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

Most described male breast lesions, such as gynecomastia, are benign. The overall incidence of male breast cancer is less than 3%. Like women, common presentations of male breast diseases are palpable lumps or tenderness. Physical examination, mammography and ultrasound are generally used for work-up of breast diseases in both women and men. However, men do not undergo screening mammograms; all male patients are examined in symptomatic cases only. Therefore, all male breast examinations are diagnostic, whereas the majority of the examinations for women are for screening purpose. The differentiation between benign and malignant breast lesions is important, especially for men, because the reported prognosis of male breast cancer is poor due to delayed diagnosis. In this article, we review the spectrum of male breast diseases, from benign to malignant, and illustrate their ultrasonographic and mammographic imaging features.

Demirjian, Aram N; Kent, Tara S; Callery, Mark P; Vollmer, Charles M

2010-01-01

Background Pancreatico-jejunostomy strictures (PJS) after pancreatiocoduodenectomy (PD) are poorly understood. Methods Patients treated for PJS were identified from all PDs (n =357) performed for all indications in our practice (2002 to 2009). Technical aspects of the original operation, as well as the presentation, management and outcomes of the resultant stricture were assessed. Results Seven patients developed a symptomatic PJS for an incidence of 2%. ‘Soft’ glands and small ducts (≤3 mm) were each present in 3/7 of the original anastomoses. Pancreatic fistula occurred in 6/7. The latency period to stricture presentation averaged 41 months. Diagnosis of PJS was confirmed by secretin magnetic resonance cholangio-pancreatography (MRCP). Therapeutic endoscopic retrograde cholangiopancreatography (ERCP) was attempted – each unsuccessfully – in four patients. All patients required operative correction of their PJS by takedown/revision of the original pancreatico-jejunal anastomoses (PJA) (n =4) ± a modified Puestow (n =2). One patient's PJS was completely inaccessible due to dense adhesions. Another patient's stricture recurred and was successfully revised with a stricturoplasty. At a mean follow-up of 25 months, all are alive, but only 4/7 are pain free. Conclusion A symptomatic PJS appears to be independent of original pathological, glandular or technical features but pancreatic fistulae may contribute. Secretin MRCP is diagnostically useful, whereas ERCP has been proven to be therapeutically ineffective. Durable resolution of symptoms after surgical revision is unpredictable. PMID:20815857

Huanglongbing (HLB) is a highly destructive citrus disease which threatens citrus production worldwide and 'Candidatus Liberibacter asiaticus' (Las), a non-culturable phloem-limited bacterium, is an associated causal agent of the disease. To better understand the physiological and molecular processes involved in host responses to Las, 2-DE and mass spectrometry analyses, as well as ICP spectroscopy analysis were employed to elucidate the global protein expression profiles and nutrient concentrations in leaves of Las-infected grapefruit plants at pre-symptomatic or symptomatic stages for HLB. This study identified 123 protein spots out of 191 spots that showed significant changes in the leaves of grapefruit plants in response to Las infection and all identified spots matched to 69 unique proteins/peptides. A down-regulation of 56 proteins including those associated with photosynthesis, protein synthesis, and metabolism was correlated with significant reductions in the concentrations of Ca, Mg, Fe, Zn, Mn, and Cu in leaves of grapefruit plants in response to Las infection, particularly in symptomatic plants. Oxygen-evolving enhancer (OEE) proteins, a PSI 9 kDa protein, and a Btf3-like protein were among a small group of proteins that were down-regulated in both pre-symptomatic and symptomatic plants in response to Las infection. Furthermore, a Las-mediated up-regulation of 13 grapefruit proteins was detected, which included Cu/Zn superoxide dismutase, chitinases, lectin-related proteins, miraculin-like proteins, peroxiredoxins and a CAP 160 protein. Interestingly, a Las-mediated up-regulation of granule-bound starch synthase was correlated with an increase in the K concentrations of pre-symptomatic and symptomatic plants. This study constitutes the first attempt to characterize the interrelationships between protein expression and nutritional status of Las-infected pre-symptomatic or symptomatic grapefruit plants and sheds light on the physiological and molecular

RESULTS: High knee extensor strength (normalized by allometric scaling) was associated with a reduced risk...... of radiographic knee OA in women (relative risk: 0.52; 95% CI: 0.29 to 0.94) but not in men (0.56; 0.27 to 1.16). High knee extensor strength did not protect against the development of symptomatic knee OA, either in women or in men. CONCLUSION: The results only partly confirm the hypothesis that high knee...

Benign prostatic hyperplasia and male lower urinary symptoms: A guide for family physicians

Directory of Open Access Journals (Sweden)

Farhad Fakhrudin Vasanwala

2017-07-01

Full Text Available Male patients with lower urinary tract symptoms (LUTS and benign prostatic hyperplasia (BPH are increasingly seen by family physicians worldwide due to ageing demographics. A systematic way to stratify patients who can be managed in the community and those who need to be referred to the urologist is thus very useful. Good history taking, physical examination, targeted blood or urine tests, and knowing the red flags for referral are the mainstay of stratifying these patients. Case selection is always key in clinical practice and in the setting of the family physician. The best patient to manage is one above 40 years of age, symptomatic with nocturia, slower stream and sensation of incomplete voiding, has a normal prostate-specific antigen level, no palpable bladder, and no haematuria or pyuria on the labstix. The roles of α blockers, 5-α reductase inhibitors, and antibiotics in a primary care setting to manage this condition are also discussed.

2011-01-01

Objective The aim of this study was to evaluate the role of three diagnostic sonographic methods, greyscale sonography (GSS), colour Doppler sonography (CDS) and spectral Doppler (SPD), in differentiating between benign and malignant salivary gland (SG) tumours. Methods 44 patients with SG masses were examined using GSS, CDS and SPD. The morphological features of each tumour were evaluated using GSS, the distribution and number of detected blood vessels were assessed using CDS, and peak systolic velocity (PSV), resistive index (RI) and pulsatility index (PI) were measured on SPD. All cases underwent excisional biopsy and a definite tissue diagnosis was obtained. Results Histopathological examination revealed that 28 of the 44 tumours were benign and 16 were malignant. GSS showed that malignant SG tumours had a significantly higher incidence of ill-defined borders and lymph node involvement than benign tumours, but there was no significant difference between benign and malignant SG tumours regarding echogenicity, homogeneity or sonographic shape. CDS demonstrated malignant tumours with significantly higher vascularity and a scattered distribution. Using SPD, malignant tumours had significantly higher PSV, RI and PI compared with benign tumours. Conclusion RI values above 0.7, PI values above 1.2, PSV values above 44.3 cm s–1, ill-defined borders, lymph node involvement, Grade 2 or 3 vascularity and hilar distribution of blood vessels should alert the clinician to suspect a malignant SG tumour. After consensus on the threshold values of PSV, RI and PI in differentiating benign from malignant SG tumours, these numbers should be incorporated into the software of ultrasound machines to guide the sonographer in his or her analysis.

diabetes has been shown to affect the peripheral vestibular end organs and is associated with an increase in the frequency of benign paroxysmal positional vertigo (BPPV). People with diabetes have higher postural sway; however, the impact of symptomatic BPPV on postural sway in individuals with diabetes is unclear. The purpose of this cross-sectional study was to examine postural sway in people with type 2 diabetes who have symptomatic, untreated BPPV (BPPVDM). fifty-two participants (mean age 56.9 ± 5.6 years) were enrolled: controls (n = 14), diabetes (n = 14), BPPV only (n = 13) and BPPVDM (n = 11). An inertial motion sensor was used to detect pelvic acceleration across five standing conditions with eyes open/closed on firm/foam surfaces. Range of acceleration (cm/s 2 ), peak velocity (cm/s) and variability of sway [root mean square (RMS)] in the anterior-posterior (AP) and medial-lateral (ML) directions were used to compare postural sway between groups across conditions. participants with BPPVDM had higher ranges of acceleration in the AP (p = 0.02) and ML (p = 0.02) directions, as well as higher peak velocity (p diabetes groups. Standing on foam with eyes closed and tandem stance were challenging conditions for people with BPPVDM. clinicians may consider using standing on foam with eyes closed and tandem standing with eyes open to assess postural control in people with BPPVDM to identify postural instability.

To investigate the benign prostatic hyperplasia (BPH) and prostate cancer in Lanzhou, an investigation of the incidence of BPH and prostate cancer in 1356 male inhabitants over 50 years of age has been carried out including I-PSS, life quality (L), volume of prostate (V) and digital rectal examination. Plasma testosterone (T) and prostate specific antigen (PSA) were assayed in 145 cases. The incidence of BPH was 35.03%, being 41.04% in urban and 30.05% in rural inhabitants. The increase of BPH has been higher in urban inhabitants (P<0.05). The incidence of prostate cancer was 2.05%, being 3.09% in urban and 2.02% in rural inhabitants, the increase of prostate cancer has been higher in urban inhabitants (P< 0.05). A significant increase of prostate specific antigen was noted in prostate cancer patients (P<0.05). Conclusions: The increase of BPH and prostate cancer has been higher in urban inhabitants. The age, diet and residential areas might associate with a higher incidence of BPH and prostate cancer

To verify the efficacy and safety of tamsulosin 0.4 mg and tamsulosin 0.2 mg compared with those of placebo in patients with lower urinary tract symptoms (LUTS) associated with benign prostatic hyperplasia (BPH). A total of 494 patients from multiple centers participated in this double-blind, randomized, phase 3 trial. Eligible patients were randomly assigned to the tamsulosin 0.4 mg group, tamsulosin 0.2 mg group or placebo group. The International Prostate Symptom Score (IPSS), maximum flow rate (Qmax), post-void residual (PVR) urine volume, blood pressure, heart rate and adverse events were compared among the three groups at 4, 8 and 12 weeks. A total of 494 BPH patients were analyzed. There were no differences in the baseline characteristics among the three groups. After 12 weeks of treatment, total IPSS was improved in the 0.2 mg and 0.4 mg tamsulosin groups; however, the extent of improvement was greater in the 0.4 mg group than in the 0.2 mg group (0.4 mg: -9.59 vs. 0.2 mg: -5.61; least-squares mean difference [95% confidence interval]: -3.95 [-5.01, -2.89], p Tamsulosin 0.4 mg and 0.2 mg appear to be superior to placebo treatment, and tamsulosin 0.4 mg is more effective than 0.2 mg in terms of total IPSS improvement. Tamsulosin 0.4 mg has favorable efficacy and tolerability in Asian men with symptomatic BPH. ClinicalTrials.gov Identifier: NCT02390882.

We investigated PET/CT diagnostic criteria for differentiating benign from malignant parotid lesions with focal 18 F-FDG uptake. The subjects of the study were 272 patients who exhibited focal 18 F-FDG uptake of the parotid gland. Sixty-eight pathologically confirmed parotid lesions from 67 patients were included. The maximum SUV (SUVmax), uptake patterns (homogeneous vs. heterogeneous), size measured by CT, maximum Housfield units (HUmax) and margins on CT (well vs. ill defined) of each parotid lesion on PET/CT images were compared with final diagnoses. Thirty- two parotid lesions were histologically proven to be malignant. There were significant differences in uptake patterns (cancer incidence, heterogeneous:homogeneous=79.2%:29.5%, p<0.0001) and margins on CT (cancer incidence, ill:well defined=84.4%:13.3%, p<0.0001) between benign and malignant lesions. The cancer risks of parotid lesions were 89.5% with heterogeneous uptake and ill-defined margins, 70.6% with heterogeneous uptake or ill-defined margins (no overlap in subjects) and 9.3% with homogeneous uptake and well-defined margins (p<0.0001). When any lesion with heterogeneous uptake or ill-defined margins was regarded as malignant, the sensitivity, positive predictive value, negative predictive value and accuracy were 90.6% (29/32) and 85.6% (58/68), respectively. For predicting malignancy, combined PET/CT criteria showed better sensitivity, NPV and accuracy than PET-only criteria, and had a tendency to have more accurate results than CT-only criteria, and had a tendency to have more accurate results than CT-only criteria. There were no significant differences in SUVmax, size or HUmax between benign and malignant lesions. Uptake patterns and margins on CT are useful PET/CT diagnostic criteria for differentiating benign from malignant lesions

In our series of 1,900 endoscopic extraperitoneal radical prostatectomies (EERPE) the incidence of symptomatic lymphocele following simultaneous pelvic lymph node dissection (PLND) is between 3 and 14% depending on the extent of lymph node dissection. We report the impact of bilateral peritoneal fenestration after completion of extraperitoneal prostatectomy and PLND on the incidence of lymphocele, postoperative pain and complications. A total of 100 consecutive patients undergoing EERPE and extended PLND were allocated into two groups. In Group A (n = 50) a 4-6 cm incision was performed bilaterally over the external iliac vessels down to the obturator fossa after completion of the main procedure. In Group B (n = 50) no peritoneal incisions were made. The postoperative assessment protocol included a visual analogue pain scale administered three times daily for 6 days, analgesia requirement, and ultrasound examination on 4th and 8th days, and 3 months postoperatively. CRP and leucocyte counts were measured on 1st and 2nd postoperative days. Complications were recorded according to our standard protocol using the Clavien classification. Three patients (6%) in Group A were found to have lymphoceles, none of which were symptomatic. Significantly more patients in Group B developed a lymphocele, (n = 16, 32%, P < 0.001) of which a significant number were symptomatic (n = 7, 14%, P < 0.001) and required laparoscopic fenestration. No significant difference was observed between the pain score in either group. Mean pain scores were 3.4 versus 3.8 at 6 h, and 0.8 versus 1.1 at 6 days, respectively. No difference in analgesia requirement, serum inflammatory markers and return to normal bowel activity was observed between the groups. This study demonstrates that peritoneal fenestration significantly reduces the incidence of both symptomatic and asymptomatic lymphocele, without an increase in postoperative morbidity. As symptomatic lymphocele is one of the most common

Recently studies have indicated the existence of both posttraumatic stress disorder (PTSD) and acute stress disorder (ASD) subtypes but no studies have investigated their mutual association. Although ASD may not be a precursor of PTSD per se, there are potential benefits associated with early identification of victims at risk of developing PTSD subtypes. The present study investigates ASD and PTSD subtypes using latent class analysis (LCA) following bank robbery (N=371). Moreover, we assessed if highly symptomatic ASD and selected risk factors increased the probability of highly symptomatic PTSD. The results of LCA revealed a three class solution for ASD and a two class solution for PTSD. Negative cognitions about self (OR=1.08), neuroticism (OR=1.09) and membership of the 'High symptomatic ASD' class (OR=20.41) significantly increased the probability of 'symptomatic PTSD' class membership. Future studies are needed to investigate the existence of ASD and PTSD subtypes and their mutual relationship. Copyright © 2016 Elsevier Ltd. All rights reserved.

Full Text Available Abstract Background Symptomatic heterotopic ossification (HO in multiple trauma patients may lead to follow up surgery, furthermore the long-term outcome can be restricted. Knowledge of the effect of surgical treatment on formation of symptomatic heterotopic ossification in polytrauma is sparse. Therefore, we test the effects of surgical treatment (plate osteosynthesis or intramedullary nailing on the formation of heterotopic ossification in the multiple trauma patient. Methods We retrospectively analysed prospectively documented data of blunt multiple trauma patients with long bone fractures which were treated at our level-1 trauma centre between 1997 and 2005. Patients were distributed to 2 groups: Patients treated by intramedullary nails (group IMN or plate osteosynthesis (group PLATE were compared. The expression and extension of symptomatic heterotopic ossifications on 3-6 months follow-up x-rays in antero-posterior (ap and lateral views were classified radiologically and the maximum expansion was measured in millimeter (mm. Additionally, ventilation time, prophylactic medication like indomethacine and incidence and correlation of head injuries were analysed. Results 101 patients were included in our study, 79 men and 22 women. The fractures were treated by intramedullary nails (group IMN n = 50 or plate osteosynthesis (group PLATE n = 51. Significantly higher radiologic ossification classes were detected in group PLATE (2.9 ± 1.3 as compared to IMN (2.2 ± 1.1; p = 0.013. HO size in mm ap and lateral showed a tendency towards larger HOs in the PLATE group. Additionally PLATE group showed a higher rate of articular fractures (63% vs. 28% in IMN while IMN demonstrated a higher rate of diaphyseal fractures (72% vs. 37% in PLATE; p = 0.003. Ventilation time, indomethacine and incidence of head injuries showed no significant difference between groups. Conclusion Fracture care with plate osteosynthesis in polytrauma patients is associated with

In light of recent controversy about the safety and efficacy of intracranial stenting, we sought to evaluate our experience with primary balloon angioplasty for symptomatic, high-grade intracranial stenosis. All intracranial angioplasty cases performed at Vanderbilt University Medical Center from 2006 to 2011 were retrospectively reviewed for degree of stenosis pre- and post-procedure. Immediate peri-procedural complications were evaluated as well as one-month and long-term outcomes. A total of 26 patients were included in the study with a mean age of 63.0 years and a mean follow-up of 350.2 days. The average pre-procedure stenosis was 71.2%. The immediate, average post-procedure stenosis was 46.6%, and the average post-procedure stenosis at last angiographic follow-up was 44.5%. Retreatment was required in only 3.8% of patients. The primary end-point of major stroke or death at 30 days was observed in 11.5%, and the overall intra-procedural complication rate was 7.7%. The incidence of stroke or death at last follow-up was 15.4%, which is comparable to the one-year stroke or death rate in the medical arm of the SAMPRISS trial. In this retrospective series, primary balloon angioplasty was found to be effective as a treatment option for symptomatic intracranial stenosis with the risk of stroke or death at 30 days higher than the medical arm of SAMPRIS but lower than the stenting arm. The one-year risk of stroke was comparable to that reported for the one-year outcomes in the SAMPRISS medical arm.

Symptomatic vaginal discharge is the most frequent symptom in women of reproductive age group. Owing to social stigma majority of affected women hesitate to seek medical consultation. Therefore the actual incidence of vaginal discharge is much more than what is reported. The aim of the study is to determine the microbiological profile of symptomatic vaginal discharge in rural area and its utility in the management of genital tract infection. This was a descriptive type of observational study, conducted in sexually active women of reproductive age group (18-45 years) attending the OPD/IPD of Obstetrics and Gynaecology Department of National Institute of Medical Sciences, Shobhanagar, Jaipur (Rajasthan), over a period of 18 months from June 2012 to December 2013. Hundred sexually active non pregnant women of reproductive age group (18-45 years) were included in the study. After taking consent general physical examination along with pelvic examination was performed. Two high vaginal swabs and blood sample were collected for various tests. Hanging drop preparation was immediately made. This was followed by gram staining and culture. Chlamydia trachomatis IgM antibody was detected by ELISA method. Out of 100 women with symptomatic vaginal discharge, specific diagnosis was obtained in 89% of cases whereas no specific aetiology was found in 11% cases. Mean age was 32.60 years. Fifty-three percent patient had Bacterial vaginosis, candidiasis was found in 14% cases, 16% had Chlamydia trachomatis infection while Trichomonas vaginalis infection was detected in 6% cases. Homogenous discharge was most prevalent (52%), followed by mucopurulant discharge in 23% of women. Patient with symptomatic vaginal discharge need to be actively managed with appropriate antimicrobial agents. Judicious management may be helpful in prevention of HIV, HPV, CIN and post infection sequelae.

Biliary stricture in chronic pancreatitis (CP) is not uncommon. Previously, all cases were managed by surgery. Nowadays, three important modes of treatment in these patients are observation, endoscopic therapy, and surgery. In the modern era, surgery is recommended only in a subset of patients who develop biliary symptoms or those who have asymptomatic biliary stricture and require surgery for intractable abdominal pain. We want to report on our experience regarding surgical management of CP-induced benign biliary stricture. Over a period of 5 years, we have managed 340 cases of CP at our institution. Bile duct stricture was found in 62 patients. But, surgical intervention was required in 44 patients, and the remaining 18 patients were managed conservatively. Demographic data, operative procedures, postoperative complications, and follow-up parameters of these patients were collected from our prospective database. A total 44 patients were operated for biliary obstruction in the background of CP. Three patients were excluded, so the final analysis was based on 41 patients. The indication for surgery was symptomatic biliary stricture in 27 patients and asymptomatic biliary stricture with intractable abdominal pain in 14 patients. The most commonly performed operation was Frey's procedure. There was no inhospital mortality. Thirty-five patients were well at a mean follow-up of 24.4 months (range 3 to 54 months). Surgery is still the best option for CP-induced benign biliary stricture, and Frey's procedure is a versatile operation unless you suspect malignancy as the cause of biliary obstruction.

Tamsulosin oral controlled absorption system (OCAS in the treatment of benign prostatic hypertrophy

Full Text Available Mischel G Neill, Rohan Shahani, Alexandre R ZlottaDivision of Urology, Department of Surgical Oncology, Princess Margaret and Mount Sinai Hospitals, University of Toronto, Toronto, CanadaAbstract: The efficacy of tamsulosin at the cost of a relatively benign side effect profile has been attributed to receptor selectivity directed at the α1a and α1d adrenergic receptor subtypes. The oral-controlled absorption system (OCAS® represents a drug delivery refinement that incorporates a matrix of gel-forming and gel-enhancing agents to promote a constant drug release independent of environmental food or fluid. There are clinical data to support the concept that drug peaks are lessened and that drug release continues throughout the alimentary tract due to the OCAS formulation. Furthermore this equates with less adverse effects on physiologic parameters. To date however improvements in cardiovascular symptoms such as dizziness, headache and syncope have not been demonstrated in healthy men. Ejaculatory dysfunction appears less problematic with the OCAS preparation. Tamsulosin OCAS may be of greatest benefit to men with cardiovascular co-morbidities taking anti-hypertensive medications that might predispose them to symptomatic hypotensive episodes. It will be necessary to evaluate this group of men more closely in further trials to determine what they stand to gain from changing medications, and then relate this to drug costs to draw a final conclusion as to the place of tamsulosin OCAS in contemporary urological practice.Keywords: lower urinary tract symptoms, benign prostatic hyperplasia, tamsulosin OCAS, safety, efficacy, tolerability

To determine the incidence of intracranial hypertension in patients with spontaneous encephalocele with cerebrospinal fluid (CSF) leak. Retrospective case review. Tertiary care neurotology practice. Patients presenting between 2008 and 2011 with spontaneous encephalocele and CSF leak in the temporal bone. Lumbar puncture with opening pressure measurement after encephalocele repair. Patient age, sex, postoperative course, body mass index, and postoperative intracranial pressure. Of the 26 patients identified with spontaneous encephalocele with CSF leak, 9 patients had postoperative lumbar puncture data. Of those 9, 89% were female subjects, and 11% were male, with a mean age of 57 and a mean BMI of 41 kg/m (morbidly obese). The mean opening pressure was 24.5 cm H(2)O. Approximately 33% had normal intracranial pressure (mean, 15 cm H(2)O; range, 10-17 cm H(2)O); 67% had elevated intracranial pressure (mean, 29 cm H(2)O; range, 23.5-40 cm H(2)O). The incidence of BIH in the general population is 0.001%. Of the 6 with intracranial hypertension, 3 (50%) were placed on acetazolamide for fundoscopic findings, postoperative headache, and/or visual changes. Mean time to LP after repair of encephalocele was 13 months (range, 4 days to 75 months). This study shows that benign intracranial hypertension is prevalent in a significant number of patients presenting with spontaneous encephalocele with CSF otorrhea at a rate much higher than is found in the general population. This finding has direct clinical implications and suggests that all patients with spontaneous encephalocele/CSF leak warrant evaluation for benign intracranial hypertension.

Objective was to characterize benign breast diseases in Eastern Nigeria and to highlight the age variations of these lesions as base line data. The Department of Morbid Anatomy, University of Nigeria Teaching Hospital, Enugu caters for over 30 million African blacks and receives 2000 surgical pathology specimens yearly. Seven hundred and twenty-two benign breast specimens were analyzed over 5 years from Ist January 2000 to 31 December 2004, out of 1050 breast samples received. Of 1050 breast specimens received, 722 (68.8%) were benign. Fibroadenoma was the most common lesion with 318 cases (44%), occurring at a mean age of 16-32 years. Next were fibrocystic changes with 165 cases (22.9%) at a mean age of 23-45 years. Normal breast in the axillary tail region was seen in 32 cases (4.4%), represented as no pathology, with a mean presentation age of 20-46 years. Low grade Phyllodes tumor had 28 cases (3.9%), presenting at an average mean age of 17-32 years. Lactating adenoma had 19 (2.6%) cases. Other lesions made up less than 3% each. Benign breast lesions peaked at the 20-24 age range and then declined. Most were females. Benign breast lesions occur more frequently than malignant breast lesions with a ratio of 2.3:1 and were presented 20 years earlier than their malignant counterparts. Fibroadenoma was the most common benign lesions followed by fibrocystic disease, similar to the findings in Western Nigeria. In Northern Nigeria, fibrocystic breast disease was more common. (author)

To examine the prevalence and incidence, clinical presentation, societal impact and comorbid conditions of benign paroxysmal positional vertigo (BPPV) in the general population. Cross-sectional, nationally representative neurotological survey of the general adult population in Germany with a two stage sampling design: screening of 4869 participants from the German National Telephone Health Interview Survey 2003 (response rate 52%) for moderate or severe dizziness or vertigo, followed by validated neurotological interviews (n = 1003; response rate 87%). Diagnostic criteria for BPPV were at least five attacks of vestibular vertigo lasting vertigo. The lifetime prevalence of BPPV was 2.4%, the 1 year prevalence was 1.6% and the 1 year incidence was 0.6%. The median duration of an episode was 2 weeks. In 86% of affected individuals, BPPV led to medical consultation, interruption of daily activities or sick leave. In total, only 8% of affected participants received effective treatment. On multivariate analysis, age, migraine, hypertension, hyperlipidaemia and stroke were independently associated with BPPV. BPPV is a common vestibular disorder leading to significant morbidity, psychosocial impact and medical costs.

Benign osseous metaplasia of the breast: Case report

Directory of Open Access Journals (Sweden)

Hassan Alyami

Full Text Available Introduction: Benign Osseous metaplasia of the breast is rare, with only a few cases reported in the literature. Here we present a case of benign osseous metaplasia of the breast presenting as a breast lump. Case presentation: 38-year-old previously well woman presented with a one-year history of bilateral breast pain and a left-sided breast lump. Ultrasound and mammography suggested calcified fibroadenoma. An ultrasound-guided true cut biopsy revealed fibrous tissue containing foci of adenosis in the presence of a myoepithelial cell layer. Excision biopsy was performed, and histopathological examination showed bone matrix deposition occupying most of the nodule with peripheral hyalinized tissue but no evidence of malignancy. A diagnosis of benign osseous metaplasia of the breast was made, and the patient recovered well without recurrence after lump excision. Discussion: Only a few cases of osseous metaplasia are reported in the literature. Most reported cases are malignant, such as in fibrosarcoma, malignant mesenchymoma, osteoid sarcoma, osteogenic sarcoma, and osteochondrosarcoma.Very few cases of osseous sarcoma are reported in benign lesions such as fibroadenoma, pleomorphic adenoma, benign mesenchymoma, phyllodes tumor, and amyloid tumor of the breast. Joshi et al. first reported a case of benign osseous metaplasia of the breast presenting as breast lump in an HIV-positive patient [18]. We, therefore, consider this case to be the second case report of benign osseous metaplasia of the breast presenting as a breast lump, but the patient had no chronic illness. Conclusion: A breast lump can be the first presentation of benign osseous metaplasia. Keywords: Benign osseous metaplasia, Breast lump, Case report

Benign symmetric lipomatosis, also known as Madelung disease, is a rare disorder characterized by fat distribution around the shoulders, arms, and neck in the context of chronic alcoholism. Complete excision of nonencapsulated lipomas is difficult. However, reports describing conservative therapeutic measures for lipomatosis are rare. The authors present the case of a 42-year-old man with a diagnosis of benign symmetric lipomatosis who had multiple, large, symmetrical masses in his neck. Multiple phosphatidylcholine injections in the neck were administered 4 weeks apart, a total of seven times to achieve lipolysis. The patient's lipomatosis improved in response to the injections, and he achieved good cosmetic results. Intralesional injection, termed mesotherapy, using phosphatidylcholine is a potentially effective therapy for benign symmetric lipomatosis that should be reconsidered as a therapeutic option for this disease.

The aim of this study was to assess the frequency and severity of new onset of diabetes mellitus (NODM) and pancreatic exocrine insufficiency (PEI) after pancreaticoduodenectomy (PD) for benign and malignant tumors. When PD is performed on patients for benign tumors, the question of long-term metabolic dysfunctions becomes of importance. Medline/PubMed, Embase, and Cochrane Library were searched for articles reporting results of measuring endocrine and exocrine pancreatic functions after PD. The methodological quality of 19 studies was assessed by means of the Newcastle-Ottawa scale and Moga-Score. The mean weighted overall percentages of NODM and PEI after PD were calculated with a 95% confidence interval (CI). Of 1295 patients, data valid-for-efficacy-analysis are based on 845 patients measuring pancreatic endocrine and on 964 patients determining exocrine functions after PD. The cumulative incidence of NODM was 40 of 275 patients (14.5%; 95% CI: 10.3-18.7) in the benign tumor group, 25 of 161 (15.5%; 95% CI: 9.9-21.2) in the malignant tumor group, and 91 of 409 patients (22.2%; 95% CI: 18.2-26.3) in the benign and malignant tumor group. Comparing the frequency of NODM after PD revealed significant differences between the groups (benign vs benign and malignant P benign and malignant P benign and malignant tumors and a significant decrease of exocrine functions contribute to a rational weighting of metabolic long-term risks following PD.

Prompted by the finding that the radiological incidence of small bowel ascariasis in the patient with gastric carcinoma was unexpectedly lower than the incidence in the normal population, a clinical study was performed to investigate possible relationship between gastric carcinoma and intestinal ascariasis. As a preliminary survey, we reviewed the radiological incidence of ascariasis in a total of 2,446 cases of upper GI series performed at the Department of Radiology, St Mary's Hospital Catholic Medical College. These included 1,573 normal subjects, 146 gastric carcinoma patients, 100 benign gastric ulcer and 249 duodenal ulcer patients and 378 other upper GI diseases. Following the preliminary study, a more accurate parasitologic study was conducted in another 578 normal subjects and 51 gastric carcinoma patients. The radiological incidences of ascaiasis in normal subjects and gastric carcinoma patients were 15.1% and 28.1%, respectively. The incidence of overall helminthiasis including ascaris lumbricoides, trichocephalus trichiurus and trichostrongyloides orientalis in normal subjects of the present series was 73.5%. This figure is virtually the same with 69.1% of the general population incidence reported by Kim, et al. (1971), but the incidence in gastric carcinoma patients was 94.1%. The high incidence pattern of overall helminthiasis in gastric carcinoma patients is, however, reversed as for as ascariasis is concerned. Thus, the incidence of ascariasis of gastric carcinoma patients was much lower than that of normal subjects (9.8% vs 19.4%). From the present observation, it is postulated that there can be some possible antagonistic relationship between evolution of gastric carcinoma and small bowel infestation of ascaris lumbricoides.

Prompted by the finding that the radiological incidence of small bowel ascariasis in the patient with gastric carcinoma was unexpectedly lower than the incidence in the normal population, a clinical study was performed to investigate possible relationship between gastric carcinoma and intestinal ascariasis. As a preliminary survey, we reviewed the radiological incidence of ascariasis in a total of 2,446 cases of upper GI series performed at the Department of Radiology, St Mary's Hospital Catholic Medical College. These included 1,573 normal subjects, 146 gastric carcinoma patients, 100 benign gastric ulcer and 249 duodenal ulcer patients and 378 other upper GI diseases. Following the preliminary study, a more accurate parasitologic study was conducted in another 578 normal subjects and 51 gastric carcinoma patients. The radiological incidences of ascaiasis in normal subjects and gastric carcinoma patients were 15.1% and 28.1%, respectively. The incidence of overall helminthiasis including ascaris lumbricoides, trichocephalus trichiurus and trichostrongyloides orientalis in normal subjects of the present series was 73.5%. This figure is virtually the same with 69.1% of the general population incidence reported by Kim, et al. (1971), but the incidence in gastric carcinoma patients was 94.1%. The high incidence pattern of overall helminthiasis in gastric carcinoma patients is, however, reversed as for as ascariasis is concerned.

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

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.)

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.

Anastomotic stenosis of the colon is not an uncommon finding; however, its frequency varies from one study to another. Traditionally, postoperative colonic stenosis is managed surgically. However, endoscopic therapy has recently become the preferred treatment modality over traditional surgery. Good short-term success has been achieved with use of endoscopic balloon dilation; however, restenosis may occur over time in 14% to 25% of patients. The current report showed the effectiveness and usefulness of an insulated-tip knife (IT-knife) for electrocautery therapy of a patient with symptomatic anastomotic colonic stenosis.

A study of the benign cementoblastoma

The benign cementoblastoma is a benign odontogenic tumor of cemental-forming tissue, which has an unlimited growth potential, The radiographic appearance of the lesion is pathognomonic and consists of a radiopaque mass surrounded by a thin radiolucent line. This mass is inseparable, radiologically, from the tooth root and is attached to it, Microscopic evaluation suggests that the lesion enlarges by peripheral growth, with the center of the neoplasm being more calcified and inactive than the periphery. We have observed two cases of benign cementoblastoma (mature calcified stage) occurred in the left mandibular first molar of 22-year old man and 14-year-old man.

To investigate whether a fixed-dose combination (FDC) of 0.5 mg dutasteride and 0.4 mg tamsulosin is more effective than watchful waiting with protocol-defined initiation of tamsulosin therapy if symptoms did not improve (WW-All) in treatment-naïve men with moderately symptomatic benign prostatic hyperplasia (BPH) at risk of progression. This was a multicentre, randomised, open-label, parallel-group study (NCT01294592) in 742 men with an International Prostate Symptom Score (IPSS) of 8-19, prostate volume ≥30 mL and total serum PSA level of ≥1.5 ng/mL. Patients were randomised to FDC (369 patients) or WW-All (373) and followed for 24 months. All patients were given lifestyle advice. The primary endpoint was symptomatic improvement from baseline to 24 months, measured by the IPSS. Secondary outcomes included BPH clinical progression, impact on quality of life (QoL), and safety. The change in IPSS at 24 months was significantly greater for FDC than WW-All (-5.4 vs -3.6 points, P tamsulosin. FDC therapy with dutasteride and tamsulosin, plus lifestyle advice, resulted in rapid and sustained improvements in men with moderate BPH symptoms at risk of progression with significantly greater symptom and QoL improvements and a significantly reduced risk of BPH progression compared with WW plus initiation of tamsulosin as per protocol. © 2015 The Authors.

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

Prothrombin fragment 1+2 is excreted in urine (uF1+2) as a result of in vivo thrombin generation and can be a marker of coagulation status after an operative procedure. This study compared uF1+2 levels in patients with symptomatic and non-symptomatic venous thromboembolism (VTE) after total knee...... replacement (TKR) and in event-free sex- and age-matched controls. Significantly higher median uF1+2 levels were seen in the VTE patients on days 1, 3, and the day of venography (mostly day 7) after TKR compared with controls. The uF1+2 levels tended to be high in some patients with symptomatic VTE; however...

Benign clavicular lesions that may mimic malignancy

Gerscovich, E.G.; Greenspan, A.; Szabo, R.M.

1991-01-01

Nontraumatic lesions of the clavicle are infrequent. Of these, malignant tumors are more common than benign lesions. From January 1988 to January 1990, we examined 17 patients with benign lesions of the clavicle; in 8, the morphologic appearance of the lesion raised the possibility of malignancy in the differential diagnosis. The radiologic findings in these patients are presented. We propose that the unique shape and embryologic development of the clavicle may contribute to the atypical, aggressive presentation of some benign lesions in that bone. (orig.)

2002-01-01

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 OBJECTIVE: The aim of this study was to compare the efficacy, safety and tolerability of Dutasteride vs Finasteride in a fixed dose combination, with a uro-selective a-blocker Tamsulosin, in the management of symptomatic BPH associated with LUTS. MATERIALS AND METHODS: 105 males between 40-80 years, clinically diagnosed as Benign prostatic hyperplasia (BPH having a baseline evaluation of their IPSS, UFR, PSA, LFT, KFT, sex health, ultrasound of prostate and PVUV, were randomized to receive a fixed dose combination therapy of Tamsulosin (0.4 mg with Finasteride (5 mg, vs Tamsulosin (0.4 mg with Dutasteride (0.5 mg, daily for six consecutive months. Follow- up at the end of the 2nd, 4th, 8th, 12th and 24th week was done with IPSS, UFR, PSA, ultrasound of Prostate, PVUV and sex health. RESULTS: There were five dropouts, three from the Finasteride arm and two from Dutasteride arm, leaving a total of 100 patients for the final evaluation. Patients in both the groups showed improvement in their symptoms score and urine flow rate from the baseline, but those with the Dutasteride combination not only showed much better improvement in their symptoms score and urine flow, but were also relieved of their obstructive symptoms earlier (10-14 days than seen in the Finasteride group (24-35 days. None of the patients had acute retention of urine (AUR during the trial. The post void urine volume was decreased more in the Dutasteride group, than in patients with Finasteride. Sexual dysfunction incidence was same in both the groups. Approximately 50% reduction in the PSA level was seen in both the groups, while LFT did not show significant difference from the baseline, in either group. Both the drugs were well tolerated, with the patient′s good compliance and with no drop-out due to adverse effects. CONCLUSION : A combination of a-adrenergic blocker and 5-ARI is the best therapeutic option for medical management of BPH as it is safe, effective and well tolerated

[With alpha blockers, finasteride and nettle root against benign prostatic hyperplasia. Which patients are helped by conservative therapy?].

Vahlensieck, W

2002-04-18

Symptomatic benign prostatic hyperplasia (BPH), which a man has a 50% chance of developing during the course of his lifetime, should receive stage-related treatment. While Vahlensieck stage I disease requires no therapy, stages II and III are indications for medication. Established medications for the treatment of BPH in current use are alpha-blockers, finasteride, and the phytotherapeutic agents pumpkin seed (cucurbitae semen), nettle root (urticae radix), the phytosterols contained in Hypoxis rooperi, rye pollen and the fruits of saw palmetto (sabalis serrulati fructus). If the patient responds, these medicaments can be given life-long, or intermittently. The hard criterion for the rational use of drug treatment of BPH is, over the long term, the reduction in the number of prostate operations. In stage IV disease surgical measures--after prior compensation of renal function--are to the fore.

Leiomyoma affects up to 50% of fertile women, leading to morbidity such as bleeding or pain. The effect of symptomatic leiomyoma on the productivity of employed women is understudied. The present study investigates productivity loss in a Swedish setting in women with symptomatic leiomyoma compared to healthy women. Women seeking care for leiomyoma and heavy menstrual bleeding (HMB) were recruited at nine Swedish sites. Healthy controls with self-perceived mild to normal menstruation were recruited at routine visits. Cases and controls were employed without option to work from home. After recruitment, all women reported the work productivity and activity impairment (WPAI) questionnaire, the pictorial blood assessment chart (PBAC) and pain on the visual analog scale (VAS). Women with symptomatic leiomyoma (n = 88) missed more working time during menses compared to asymptomatic controls (n = 34): 7.6 vs 0.2% p = 0.003. The proportion of impairment while working was also significantly higher in women with symptomatic leiomyoma (43.8 vs 12.1% p100). Symptomatic leiomyoma leads to loss of working hours as well as loss of productivity during working hours, and affects women in other daily activities. Increased awareness of the impact of leiomyomas on women's lives is needed, and timely and appropriate management of the symptomatic leiomyomas could improve work productivity and quality of life.

Common benign gynaecological diseases, such as leiomyoma, adenomyosis, endometriosis, and mature teratoma, rarely undergo malignant transformation. Benign transformations that may mimic malignancy include benign metastasizing leiomyoma, massive ovarian oedema, decidualization of endometrioma, and rupture of mature teratoma. The aim of this review is to provide a contemporary overview of imaging findings in malignant and apparent malignant transformation of benign gynaecological disease.

Pharmacological treatment of the benign prostatic hyperplasia

2011-01-01

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 aα 1 -adrenoceptors (ADR). The pharmacological treatment of the benign prostatic hyperplasia includes the prostatic 5aα-reductase inhibitors, the aα 1 -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 aα 1 -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

The purpose of this study is to assess the MR findings of symptomatic osteochondromas. We evaluated 31 patients who between July, 1994 and May, 1997 underwent MR imaging for symptomatic osteochondroma. Fourteen were males and 17 were females, and their ages ranged from 8 to 49 (mean, 23) years. Using T1WI, T2WI and gadolinium-DTPA-enhanced T1WI, images were analysed according to signal intensity in the osseous component of the osteochondroma, thickness of the cartilage cap, and associated change in surrounding soft tissue. Clinical manifestation included a palpable mass or tendency to grow (n=22) and pain on movement (n=9). Complications were of three types : that which followed change in the osseous component of the tumor, associated change in surrounding soft tissue, and malignant transformation. In the osseous component, bone marrow edema or contusion was seen in 21 cases (67.7%), and in two (65%), fracture was observed. In surrounding soft tissue, muscle impingement was seen in 21 cases (67.7%), bursitis was in 7 cases (22.6 %), tenosynovitis in seven (22.6 %), and vascular compression in five (16.1 %). In three cases (9.7%), transformation to chondrosarcoma had occurred; two of these were derived from osteochondromatosis and one from a single osteochondroma. The thickness of the cartilage cap was as follow : 10 mm (n=3). In patients with symptomatic osteochondroma, MR imaging is useful for detecting both complications and malignant transformation.

A fall in the postpneumonectomy fluid level is considered a sign of bronchopleural fistula (BPF) requiring surgical intervention. We have discovered however that in rare asymptomatic patients, this event may not require aggressive surgical treatment. After seeing a case of benign emptying of the postpneumonectomy space (BEPS), we surveyed 28 surgeons to determine its incidence and characteristics. Forty-four cases of BEPS were reported by 23 survey respondents. Among 7 fully documented cases from 4 institutions, we defined the following criteria: the patient must be asymptomatic (no fever, white cell count elevation, or fluid expectoration), negative culture results if fluid sampled (patient not receiving antibiotics), no BPF at bronchoscopy or ventilation scintigraphy scan (or both), and recovery without drainage, or retrospective assessment that the intervention was unnecessary. BEPS occurred between 5 days and 152 days after pneumonectomy (6 cases right pneumonectomy and 1 case left pneumonectomy). Four patients underwent no treatment, 1 patient underwent thoracoscopic exploration (sterile) and closure after antibiotic irrigation, 1 patient underwent thoracoscopic exploration alone, and 1 patient underwent open window thoracostomy (sterile) with eventual closure. In all 7 patients (except the patient who underwent the open window procedure) the space refilled within 8 weeks; no patient experienced a subsequent empyema/BPF. Four patients who met the initial criteria for BEPS went on to experience empyema. The incidence of BEPS appears related to pneumonectomy volume, particularly extrapleural pneumonectomy. Using surgeon volume assumptions, the incidence of BEPS is 0.65%. To our knowledge, BEPS is a previously unreported occurrence. We hypothesize that it results from postoperative intrapleural pressure shifts, with or without a microscopic BPF, that drive fluid out of the pleural space while failing to cause contamination. Awareness of BEPS' existence may allow

We assessed the effect of neutral electrolyzed water (NEW) on the incidence of rot on tomato ( Solanum lycopersicum L.) fruits inoculated with Fusarium oxysporum , Galactomyces geotrichum , and Alternaria sp. at sites with lesions. The inoculated fruits were treated with NEW at 10, 30, and 60 mg liter -1 active chlorine, with copper oxychloride fungicide, and with sterile distilled water (control) for 3, 5, and 10 min. In the experiment with F. oxysporum , 50 to 80% of the control fruits and 50 to 60% of the fruits treated with the fungicide exhibited symptoms of rot at the inoculated sites. The lowest incidence recorded was 30% for fruits treated with NEW at 60 mg liter -1 active chlorine with an immersion time of 5 min. In the experiment with G. geotrichum , incidence of rot on control fruits was 70 to 90%, and for treatment with fungicide rot incidence was 50 to 90%. NEW at 60 mg liter -1 active chlorine significantly reduced incidence of symptomatic fruit: only 30% of the inoculated fruits washed for 5 min had damage from rot. In the experiment with Alternaria sp., 60 to 90% of the fruits in the control group and 60 to 70% of the fruits in the fungicide group were symptomatic. The lowest incidence was recorded for the treatment in which the fruits were submerged in NEW with 60 mg liter -1 active chlorine for 3 min. In this group, 40 to 50% of the fruits exhibited symptoms of rot. These results were obtained 8 days after inoculation. NEW, with 60 mg liter -1 active chlorine, significantly reduced incidence of rot symptoms on fruits inoculated with one of the experimental fungi relative to the control (P ≤ 0.05). NEW at 60 mg liter -1 is effective in the control of fungal rot in tomatoes.

Those older than 60 are prone to develop Acrodynia symptomatic epilepsy. Generalized epileptic seizure were often seen. Secondary to Cerebrovascular Disease epilepsy die to cortical lesion are more easily seem than subcortical lesion. Early epilepsy is more than late epilepsy. Conclusion: The cause of symptomatic epilepsy after cerebrovascular disease is not same in different types and course of CVD. Those who developed epilepsy particularly epilepsy continua would have bad prognosis

Benign Metastatic Leiomyoma Presenting as a Hemothorax

Full Text Available Uterine leiomyomas have been reported to metastasize to various organs including the lungs, skeletal muscles, bone marrow, peritoneum, and heart. They may present with symptoms related to the metastases several years after hysterectomy. These tumors regress after menopause, and it is rare to detect active tumors in postmenopausal women. Despite their ability to metastasize, they are considered to be benign due to the lack of anaplasia. Pulmonary benign metastasizing leiomyoma is usually detected in the form of pulmonary nodules incidentally on imaging. Tissue biopsy of these nodules is required to identify them as benign metastasizing leiomyomas. Immunohistochemical analysis and molecular profiling may further help detect any malignant transformation in it. Untreated pulmonary benign metastasizing leiomyoma may result in the formation of cystic structures, destruction of lung parenchyma, and hemothorax and may cause respiratory failure. Surgical resection and hormonal therapy help prevent progression of this disease and provide an avenue for a cure.

Nodular goiter is one of the most common benign lesions in thyroid nodule. The main treatment of the disease is still the traditional surgical resection, however there are many problems such as general anesthesia, surgical scar, postoperative thyroid or parathyroid function abnormalities, and high nodules recurrence rate in residual gland. The purpose of this study was to compare the efficacy, safety, and cost-effectiveness of 2 treatment methods, surgery and radiofrequency ablation, for the treatment of benign thyroid nodules. From May 2012 to September 2013, 200 patients with nodular goiters who underwent surgery (group A) and 200 patients treated by radiofrequency ablation (group B) were enrolled in this study. Inclusion criteria were the following: 1) cosmetic problem, 2) nodule-related symptoms, 3) hyperfunctioning nodules related to thyrotoxicosis, and 4) refusal of surgery (for group B). An internally cooled radiofrequency ablation system and an 18-ga internally cooled electrode were used. We compared the 2 groups in terms of efficacy, safety, and cost-effectiveness during a 1-year follow-up. After radiofrequency ablation, the nodule volume decreased significantly from 5.4 to 0.4 mL (P = .002) at the 12-month follow-up. The incidence of complications was significantly higher from surgery than from radiofrequency ablation (6.0% versus 1.0%, P = .002). Hypothyroidism was detected in 71.5% of patients after surgery but in none following radiofrequency ablation. The rate of residual nodules (11.9% versus 2.9%, P = .004) and hospitalization days was significantly greater after surgery (6.6 versus 2.1 days, P radiofrequency ablation are both effective treatments of nodular goiter. Compared with surgery, the advantages of radiofrequency ablation include fewer complications, preservation of thyroid function, and fewer hospitalization days. Therefore, radiofrequency ablation should be considered a first-line treatment for benign thyroid nodules. © 2015 by American

Vibro-acoustography (VA) is a newly developed imaging technology that is based on low-frequency vibrations induced in the object by the radiation force of ultrasound. VA is sensitive to the dynamic characteristics of tissue. Here, we evaluate the performance of VA in identifying benign lesions and compare the results to those of mammography. An integrated mammography-VA system designed for in vivo breast imaging was tested on a group of female volunteers, age ≥ 18 years, with suspected breast lesions based on clinical examination. A set of VA scans was acquired after each corresponding mammography. Most lesions were classified as benign based on their histological results. However, in 4 cases, initial diagnosis based on clinical imaging determined that the lesions were cysts. These cysts were aspirated with needle aspiration and disappeared completely under direct ultrasound visualization. Therefore, no biopsies were performed on these cases and lesions were classified as benign based on clinical findings per clinical standards. To define the VA characteristics of benign breast masses, we adopted the features that are normally attributed to such masses in mammography. In a blinded assessment, three radiologists evaluated the VA images independently. The diagnostic accuracy of VA for detection of benign lesions was assessed by comparing the reviewers’ evaluations with clinical data. Out of a total 29 benign lesions in the group, the reviewers were able to locate all lesions on VA images and mammography, 100% with (95% confidence interval (CI): 88% to 100%). Two reviewers were also able to correctly classify 83% (95% CI: 65% to 92%), and the third reviewer 86% (95% CI: 65% to 95%) of lesions, as benign on VA images and 86% (95% CI: 69% to 95%) on mammography. The results suggest that the mammographic characteristics of benign lesion may also be used to identify such lesions in VA. Furthermore, the results show the ability of VA to detect benign breast

changes was between 2 and 8.5 months after radiation therapy. Two risk factors appeared to have significant impact when all incidences were considered: proton portion of tumor dose > 55 CGE (p=.023), and spinal cord surface dose ≥ 60 CGE (p=.045). For patients receiving 55 CGE to >1.5cc of spinal cord, the risk of developing imaging changes was significantly higher (p=.0074). Age < 40 years was found to be correlated with higher incidence of Lhermitt's syndrome (p=.002). No variable was significant for predicting incidence of sensory or motor deficits. Conclusions: For chordomas and chondrosarcomas of the cervical spine, requiring high radiation doses, the guidelines of limiting maximum spinal cord surface dose to ≤ 64 CGE and maximum spinal cord center dose to ≤ 53 CGE appears safe. For the patients who had been treated within the above tolerance dose, none of them had developed motor deficits. Both a significant dose response relationship as well as volume effect for symptomatic or asymptomatic spinal cord changes were observed. The incidence of 1 patient, who developed motor damage after higher radiation doses to the spinal cord than generally allowed, emphasizes the importance of strict guidelines for critical, normal tissues in high dose, conformal radiation treatment

Failure to differentiate benign and malignant hilar bile duct stenosis may lead to inappropriate treatment. We retrospectively analyzed the methods for differentiation. A total of 53 patients with hilar bile duct stenosis were included, comprising 41 malignant cases (hilar cholangiocarcinoma) and 12 benign cases (six primary sclerosing cholangitis and six IgG4-associated sclerosing cholangitis). Data of clinical histories, laboratory tests, imaging studies, and liver pathologies were collected, and comparison was made between benign and malignant groups. Compared with malignant group, patients in the benign group were more likely to have multiorgan involvement of clinical histories (P < 0.001). There was no difference on bilirubin, liver enzyme, and serum tumor marker between the two groups, whereas serum IgG4 levels were higher in the benign group (P = 0.003). Patients in the benign group were more likely to have pancreatic changes (P < 0.001) and multiple-segmental bile duct stenosis (P < 0.001) on imaging. Compared with the malignant group, patients in the benign group were more likely to show severe periportal inflammation in noninvolved liver (P < 0.001), fibrosis around intrahepatic bile duct (P < 0.001), and more IgG4-positive plasma cells (P < 0.001) on liver pathology. Benign lesion should be considered for patients with history of multiorgan involvement, pancreas changes, or multiple-segmental bile duct stenosis on imaging. Liver biopsy could be helpful for differential diagnosis before surgery. Copyright © 2016 Elsevier Inc. All rights reserved.

The objective was to evaluate the use of fluorodeoxyglucose positron emission tomography (FDG-PET) in differentiating benign from malignant compression fractures. In a retrospective analysis, we identified 33 patients with 43 compression fractures who underwent FDG-PET. On FDG-PET the uptake pattern was recorded qualitatively and semiquantitatively and fractures were categorized as benign or malignant. Standardized uptake values (SUV) were obtained. MRI, CT, and biopsy results as well as clinical follow-up for 1-3 years served as standards of reference. The Student's t test was used to determine whether there was a statistically significant difference between the SUV for benign and malignant compression fractures. There were 14 malignant and 29 benign compression fractures, including 5 acute benign fractures. On FDG-PET, 5 benign fractures were falsely classified as malignant (false-positive). Three of these patients underwent prior treatment with bone marrow-stimulating agents. There were two false-negative results. Sensitivity, specificity, positive predictive value, negative predictive value, and accuracy of FDG-PET in differentiating benign from malignant compression fractures were 86%, 83%, 84%, 71%, and 92% respectively. The difference between SUV values of benign and malignant fractures was statistically significant (1.9 ± 0.97 for benign and 3.9 ± 1.52 for malignant fractures, p < 0.001). SUV of benign acute and chronic fractures were not statistically significant. Fluorodeoxyglucose positron emission tomography is useful in differentiating benign from malignant compression fractures. Therapy with bone marrow-stimulating agents can mimic malignant involvement. (orig.)

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)

Pain and focal masses in the foot and ankle are frequently encountered and often initiate a workup including imaging. It is important to differentiate benign lesions from aggressive benign or malignant lesions. In this review, multiple examples of osseous and soft tissue tumors of the foot and ankle will be presented. Additionally, the compartmental anatomy of the foot and ankle will be discussed in terms of its relevance for percutaneous biopsy planning and eventual surgery. Finally, a general overview of the surgical management of benign, benign aggressive and malignant tumors of the foot and ankle will be discussed. (orig.)

The treatment of Tarlov cysts is challenging and difficult. The objective of our study was to describe the security and efficacy of the subcutaneous infusion port for drainage of symptomatic Tarlov cysts. The authors executed a retrospective review of data from 5 symptomatic Tarlov cysts patients who were treated using a subcutaneous infusion port from June 2014 to July 2017. Numerical Rating Scale scores and the Japanese Orthopedic Association scores of back pain were analyzed. Complications and adverse effects on postoperative days 1, 7, 14, and 28 were also analyzed. The mean follow-up was 12.6 months. Five adults (3 females and 2 males) who had been symptomatic received a subcutaneous infusion port. After treatment, all patients experienced pain relief and pain alleviation lasted from 1 day to 3 years without complications and adverse effects. A subcutaneous infusion port is a useful treatment option for symptomatic Tarlov cysts. When the patients' symptoms returned and the cysts repressurized, we quickly and simply drained the cysts by using the infusion port. Copyright © 2018 Elsevier Inc. All rights reserved.

The benign cystic peritoneal mesothelioma (BCPM) is a rare neoplasm affecting mainly females at reproductive age. The natural history and physiopathology of the BCPM are not entirely known. It is mainly characterized by the lack of malignant elements, no tendency to metastasis and by a pervasive tendency to generate local recurrences after surgical removal. The clinical manifestations are insidious, uncharacteristic; the benign cystic peritoneal mesothelioma is often discovered during a surgical procedure addressing another condition. Imaging tests can raise the suspicion of BCPM but the diagnostic can only be confirmed by histopathological examination corroborated with an immunohistochemical analysis. There are no long term studies dictating a single therapeutic attitude but a high risk of local recurrences and the possibility of transformation into malignant mesothelioma have lead to the current tendency towards an aggressive treatment of the tumor. We present the case of a recurrent benign cystic peritoneal mesothelioma in a 40 years old female patient, emphasizing the therapeutic approach and the role of radical surgery in the treatment of BPCM.

Apical periodontitis of endodontic origin may develop as a result of cooperative interactions among herpesviruses, specific pathogenic bacteria and tissue-destructive inflammatory mediators. This study sought to identify the presence of Epstein-Barr virus (EBV) and human cytomegalovirus (HCMV) transcripts in symptomatic and asymptomatic periapical lesions of individuals living in Iran. Fifty endodontic patients (28 with symptomatic periapical lesions and 22 with asymptomatic periapical lesions) were included in the study. In each study subject, a microbiological periapical sample was collected using a curette in conjunction with periapical surgery. A reverse transcription-polymerase chain reaction assay was used to identify transcripts of EBV and HCMV. Human cytomegalovirus transcript was detected in 15 of the 28 (53.6%) symptomatic and in six of the 22 (27.3%) asymptomatic periapical study lesions (significant difference between symptomatic and asymptomatic lesions; P = 0.03, chi-square test). Epstein-Barr virus transcript was identified in one symptomatic and in two asymptomatic periapical lesions. This study establishes that HCMV transcription is common in apical periodontitis and is most frequent in symptomatic lesions. The high frequency of active herpesvirus infections in severe apical periodontitis changes the pathogenic paradigm of the disease and may also have preventive and therapeutic implications.

Peripheral artery disease (PAD), a diffuse manifestation of atherothrombosis, is a major cardiovascular threat. Although platelets are primary mediators of atherothrombosis, their role in the pathogenesis of PAD remains unclear. The authors sought to investigate the role of platelets in a cohort of symptomatic PAD. The authors profiled platelet activity, mRNA, and effector roles in patients with symptomatic PAD and in healthy controls. Patients with PAD and carotid artery stenosis were recruited into ongoing studies (NCT02106429 and NCT01897103) investigating platelet activity, platelet RNA, and cardiovascular disease. Platelet RNA sequence profiling mapped a robust up-regulation of myeloid-related protein (MRP)-14 mRNA, a potent calcium binding protein heterodimer, in PAD. Circulating activated platelets were enriched with MRP-14 protein, which augmented the expression of the adhesion mediator, P-selectin, thereby promoting monocyte-platelet aggregates. Electron microscopy confirmed the firm interaction of platelets with monocytes in vitro and colocalization of macrophages with MRP-14 confirmed their cross talk in atherosclerotic manifestations of PAD in vivo. Platelet-derived MRP-14 was channeled to monocytes, thereby fueling their expression of key PAD lesional hallmarks and increasing their directed locomotion, which were both suppressed in the presence of antibody-mediated blockade. Circulating MRP-14 was heightened in the setting of PAD, significantly correlated with PAD severity, and was associated with incident limb events. The authors identified a heightened platelet activity profile and unraveled a novel immunomodulatory effector role of platelet-derived MRP-14 in reprograming monocyte activation in symptomatic PAD.

Lasers have been used for symptomatic Benign Prostatic Hyperplasia (BPH) in both contact and non-contact modes with reported success rates equivalent to that of Transurethral Resection of Prostate (TURP). A new high power diode laser (Phototome), capable of delivering up to 50 watts of 1000 nm wavelength laser power via a 1 mm quartz fiber, was used to treat 15 patients with symptomatic BPH. Five patients had acute retention, 3 had long term catheter (7 - 48 months), and 8 had severe prostatism. Spinal anesthesia was used in 11 patients, and 4 patients had local anesthesia and intravenous sedation. Four quadrant coagulation with an angle firing probe delivering 50 watts of laser power for 60 seconds in one quadrant was used as the core of the treatment in 11 patients, contact vaporization of BPH tissue was performed in one patient using a 4.5 mm ball tip was used in one patient and three patients with bladder neck stenosis had bladder neck incision performed using a 1 mm quartz fiber delivering 30 watts of laser power. A foley catheter was left indwelling and removed after 5 - 7 days. All patients except one were catheter free after a mean of 8 days. One patient continued to have severe prostatism and had a TURP performed with good results after 3 months of his laser prostatectomy procedure. AUA symptom scores available in 11 patients was found to be 4 after 1 - 3 months of the initial procedure.

Benign breast myoepithelioma

Full Text Available Myoepithelioma of the breast is very rare. Breast myoepithelioma can develop in women from their early 20s right up to their 80s, but it is most common in women over 50. We report a case of 20-year-old female, who presented with a well-defined breast lump of 3 × 3 cm in size. Fine needle aspiration was performed. The cytological findings revealed good cellularity comprising monomorphic loosely cohesive sheets of plasmacytoid, round to polygonal cells with round to ovoid eccentrically placed nuclei, finely dispersed chromatin, and moderate amount of cytoplasm. On the basis of cytological findings, a diagnosis of benign myoepithelioma (plasmacytoid type was made which was confirmed on histopathologic examination. The breast is a very rare localization for this type of tumor. The benign character of the disease in conjunction with its slow progression could delay its detection and diagnosis. A detailed pathology examination is a prerequisite for avoidance of misleading diagnosis.

The purpose of this study is to assess the MR findings of symptomatic osteochondromas. We evaluated 31 patients who between July, 1994 and May, 1997 underwent MR imaging for symptomatic osteochondroma. Fourteen were males and 17 were females, and their ages ranged from 8 to 49 (mean, 23) years. Using T1WI, T2WI and gadolinium-DTPA-enhanced T1WI, images were analysed according to signal intensity in the osseous component of the osteochondroma, thickness of the cartilage cap, and associated change in surrounding soft tissue. Clinical manifestation included a palpable mass or tendency to grow (n=22) and pain on movement (n=9). Complications were of three types : that which followed change in the osseous component of the tumor, associated change in surrounding soft tissue, and malignant transformation. In the osseous component, bone marrow edema or contusion was seen in 21 cases (67.7%), and in two (65%), fracture was observed. In surrounding soft tissue, muscle impingement was seen in 21 cases (67.7%), bursitis was in 7 cases (22.6 %), tenosynovitis in seven (22.6 %), and vascular compression in five (16.1 %). In three cases (9.7%), transformation to chondrosarcoma had occurred; two of these were derived from osteochondromatosis and one from a single osteochondroma. The thickness of the cartilage cap was as follow : < 5 mm (n=16), 5-10 mm (n=12), and > 10 mm (n=3). In patients with symptomatic osteochondroma, MR imaging is useful for detecting both complications and malignant transformation. (author). 21 refs., 1 tab., 6 figs.

The aim of this study was to compare the morphology, radiological stage, conspicuity, and computer-assisted detection (CAD) characteristics of colorectal cancers (CRC) detected by computed tomographic colonography (CTC) in screening and symptomatic populations. Two radiologists independently analyzed CTC images from 133 patients diagnosed with CRC in (a) two randomized trials of symptomatic patients (35 patients with 36 tumours) and (b) a screening program using fecal occult blood testing (FOBt; 98 patients with 100 tumours), measuring tumour length, volume, morphology, radiological stage, and subjective conspicuity. A commercial CAD package was applied to both datasets. We compared CTC characteristics between screening and symptomatic populations with multivariable regression. Screen-detected CRC were significantly smaller (mean 3.0 vs 4.3 cm, p < 0.001), of lower volume (median 9.1 vs 23.2 cm 3 , p < 0.001) and more frequently polypoid (34/100, 34 % vs. 5/36, 13.9 %, p = 0.02) than symptomatic CRC. They were of earlier stage than symptomatic tumours (OR = 0.17, 95 %CI 0.07-0.41, p < 0.001), and were judged as significantly less conspicuous (mean conspicuity 54.1/100 vs. 72.8/100, p < 0.001). CAD detection was significantly lower for screen-detected (77.4 %; 95 %CI 67.9-84.7 %) than symptomatic CRC (96.9 %; 95 %CI 83.8-99.4 %, p = 0.02). Screen-detected CRC are significantly smaller, more frequently polypoid, subjectively less conspicuous, and less likely to be identified by CAD than those in symptomatic patients. (orig.)

Full Text Available Benign lesions of vocal folds are common disorders. Fifty percent of patients who have sound complaints are found to have these lesions after endoscopic and stroboscopic examinations. Benign vocal fold diseases are primarily caused by vibratory trauma. However they may also occur as a result of viral infections and congenital causes. These lesions are often presented with the complaints of dysphonia. [Archives Medical Review Journal 2013; 22(1.000: 86-95

Full Text Available Abstract Background Benign neutropenia, i.e., neutropenia not associated with an increased risk of infection, may result in serious medical consequences when a 'standard' definition of neutropenia (absolute neutrophil count (ANC 9cells/L is universally applied to all races. The aims of this study were to determine the prevalence of benign neutropenia among healthy Arabs and evaluate its mode of inheritance. Methods ANCs were studied prospectively amongst a healthy indigenous population (n = 1032 from the United Arab Emirates undergoing a nation-wide sickle-cell and thalassemia screening program. The mean neutrophil count and the prevalence of benign neutropenia were compared by age, sex and amongst various tribes. Results The mean neutrophil count (× 109cells/L was 3.3 (range 0.95–7.6. Benign neutropenia was present in 110 (10.7% subjects of whom 24 (2.3% individuals had moderate neutropenia (ANC 0.5 – 1.0 × 109 cells/L. In the 22 tribe-family groups, the prevalence of benign neutropenia varied between 0% and 38%. Benign neutropenia showed no difference in the frequency amongst the sexes (p = 0.23 and it was independent of age (Spearman's rho = 0.05, p = 0.13. The age-related mean neutrophil count was the lowest in Arabs when compared with other ethnic groups (Blacks, Europeans and Mexicans. The inheritance of benign neutropenia was consistent with an autosomal dominant pattern; however, the diversity of observed phenotypes suggested the presence of more than one genetic variant for this trait. Conclusion Arabs have a high prevalence of benign neutropenia that may be inherited as an autosomal dominant trait.

Full Text Available The first non-vitamin K antagonist oral anticoagulant (NOAC introduced to the market in Japan was dabigatran in March 2011, and three more NOACs, rivaroxaban, apixaban, and edoxaban, have since become available. Randomized controlled trials of NOACs have revealed that intracranial hemorrhage (ICH occurs less frequently with NOACs compared with warfarin. However, the absolute incidence of ICH associated with NOACs has increased with greater use of these anticoagulants, and we wanted to explore the incidence, clinical characteristics, and treatment course of patients with NOACs-associated ICH.We retrospectively analyzed the characteristics of symptomatic ICH patients receiving NOACs between March 2011 and September 2014.ICH occurred in 6 patients (5 men, 1 woman; mean ± SD age, 72.8 ± 3.2 years. Mean time to onset was 146.2 ± 111.5 days after starting NOACs. Five patients received rivaroxaban and 1 patient received apixaban. None received dabigatran or edoxaban. Notably, no hematoma expansion was observed within 24 h of onset in the absence of infusion of fresh frozen plasma, activated prothrombin complex concentrate, recombinant activated factor VIIa or hemodialysis. When NOAC therapy was initiated, mean HAS-BLED and PANWARDS scores were 1.5 ± 0.5 and 39.5 ± 7.7, respectively. Mean systolic blood pressure was 137.8 ± 15.9 mmHg within 1 month before spontaneous ICH onset.Six symptomatic ICHs occurred early in NOAC therapy but hematoma volume was small and did not expand in the absence of infusion of reversal agents or hemodialysis. The occurrence of ICH during NOAC therapy is possible even when there is acceptable mean systolic blood pressure control (137.8 ± 15.9 mmHg and HAS-BLED score ≤ 2. Even stricter blood pressure lowering and control within the acceptable range may be advisable to prevent ICH during NOAC therapy.

Full Text Available Benign fibroushistiocytoma is a benign connective tissue tumor rarely seen affecting the head and neck region. These tumors were believed to be of histiocytic origin as they are comprised of cells, which showed spindled morphology and cells with a round histiocytic appearance. The current concept consents that the lesional cells rather represent a fibroblastic differentiation. Diagnosis of these tumors proves to be challenging even with the use of immunohistochemistry due to lack of any specific markers. Here, we describe a case which presented in the gingiva mimicking a reactive lesion, which in fact was a tumor.

To describe the clinical and laboratory features of benign acute childhood myositis. 40 children of BACM were seen during October 2001 to February 2002, 22 (52%) were male with mean age of 5.3 years. Duration of illness was 3.97 days. Preceding symptoms included fever, leg pain, vomiting and inability to walk. A provisional diagnosis of viral myositis was made in 26 (66%). Guillian Barre Syndrome was the most common referral diagnosis. 11 (27.5%) children had leucopenia with lymphocytic response and 16 (40%) had thrombocytopenia. CRP was negative in 32 (80%). CPK was markedly elevated (more than 1000 IU/l) in 18 (45%) and more than 500 IU/l in 11 (27.5%) remaining between 200 to 500 IU/l. Associated features were hepatitis (elevated SGOT & SGPT) in 28 (70%) and shock in 5 (12.5%). Serological test were indicative of dengue virus (Elisa PAN BIO) in 20 (50%) of which 8 (25%) were primary dengue and 12 (30%) were secondary dengue. The outcome of therapy mainly supportive were excellent. Benign acute myositis occurs often in association with viral infection. In the present study, Dengue virus was positive in 20 (50%) children. Benign acute myositis can be differentiated from more serious causes of walking difficulty by presence of calf and thigh muscle tenderness on stretching, normal power and deep tendon reflex and elevated CPK.

Background: The radioactive iodine therapy for differentiated thyroid cancer can produce severe and frequent salivary symptoms, during the treatment or later. Aim: To analyze the incidence, severity and characteristics of the salivary signs and symptoms in these patients. Patients and Method: Retrospective and descriptive anal isis of 106 patients with confirmed diagnosis of differentiated thyroid cancer, treated with surgery and radioactive iodine, that completed a telephonic survey for the evaluation of salivary symptoms. Results: 26 (24.52%) patients presented with salivary symptoms or signs after the radioactive iodine therapy (mean 5 months). The average doses of I 131 was 128,5 mCi. Xerostomy, pain, xeroftalmy, inflammation, sialoadenitis and dysgeusia, were the most frequent clinical symptoms. Conclusions: After radioactive iodine therapy the salivary symptoms and signs incidence is high. We conclude that the indication for this treatment must be selective, but in accordance with the oncological risk of each patient

Surgery has been the classic treatment of choice for benign cystic diseases, including lymphatic malformation, ranula, branchial cleft cyst, thyroglossal duct cyst, thyroid cyst, parathyroid cyst, and lymphocele. However, surgery is associated with a tendency toward recurrence and may be accompanied by various complications, such as nerve injuries, vascular injuries, and scar formation. Therefore, sclerotherapy using various agents has been applied successfully to treatment of benign cystic diseases in the neck. This editorial reviews the use of various sclerotic agents and application of sclerotherapy to benign cystic diseases in the neck.

Full Text Available BACKGROUND/OBJECTIVES: Chronic heart failure (CHF is one of the most important public health concerns in the industrialized world having increasing incidence and prevalence. Although there are several studies describing the prevalence of heart failure with reduced ejection fraction (HFREF and heart failure with normal ejection fraction (HFNEF in selected populations, there are few data regarding the prevalence and the determinants of symptomatic heart failure in the general population. METHODS: Cross-sectional data of a population-based German sample (1,779 subjects aged 45-83 years were analyzed to determine the prevalence and determinants of chronic SHF and HFNEF defined according to the European Society of Cardiology using symptoms, echocardiography and serum NT-proBNP. Prevalence was age-standardized to the German population as of December 31st, 2005. RESULTS: The overall age-standardized prevalence of symptomatic CHF was 7.7% (95%CI 6.0-9.8 for men and 9.0% (95%CI 7.0-11.5 for women. The prevalence of CHF strongly increased with age from 3.0% among 45-54- year-old subjects to 22.0% among 75-83- year-old subjects. Symptomatic HFREF could be shown in 48% (n = 78, symptomatic HFNEF in 52% (n = 85 of subjects with CHF. The age-standardized prevalence of HFREF was 3.8 % (95%CI 2.4-5.8 for women and 4.6 % (95%CI 3.6-6.3 for men. The age-standardized prevalence of HFNEF for women and men was 5.1 % (95%CI 3.8-7.0 and 3.0 % (95%CI 2.1-4.5, respectively. Persons with CHF were more likely to have hypertension (PR = 3.4; 95%CI 1.6-7.3 or to have had a previous myocardial infarction (PR = 2.5, 95%CI 1.8-3.5. CONCLUSION: The prevalence of symptomatic CHF appears high in this population compared with other studies. While more women were affected by HFNEF than men, more male subjects suffered from HFREF. The high prevalence of symptomatic CHF seems likely to be mainly due to the high prevalence of cardiovascular risk factors in this population.

Nerve Invasion by Epithelial Cells in Benign Breast Diseases

2009-03-01

Full Text Available Nerve invasion by glandular epithelial cells in a lesion is usually regarded as invasive carcinoma. However, some benign conditions in the pancreas, prostate, breast and other organs may show involvement of nerve bundles by benign epithelial cells. We report an 18-year-old female with nerve invasion in benign breast disease. The lesion in her right breast revealed fibrocystic changes with ductal hyperplasia and stromal sclerosis. Perineural and intraneural involvement by bland-looking small ducts lined by 2 layers of cells including an outer layer of myoepithelial cells were found, suggestive of benign nerve invasion. There was no evidence of malignant cells in any of the sections. The patient remains well after 31 months of follow-up. About 44 cases of nerve invasion in benign breast diseases have been reported in the literature. It is necessary to carefully evaluate nerve involvement in breast lesions to avoid over-diagnosis and inappropriate operation.

Full Text Available The quest for neuroprotective drugs to slow the progression of neurodegenerative diseases (NDDs, including Alzheimer's disease (AD, Parkinson's disease (PD, and Huntington's disease (HD, has been largely unrewarding. Preclinical evidence suggests that repurposing quetiapine, lithium, valproate, fluoxetine, donepezil, and memantine for early and pre-symptomatic disease-modification in NDDs may be promising and can spare regulatory barriers. The literature of these psychotropics in early stage and pre-symptomatic AD, PD, and HD is reviewed and propitious findings follow. Mild cognitive impairment (MCI phase of AD: salutary human randomized controlled trial findings for low-dose lithium and, in selected patients, donepezil await replication. Pre-symptomatic AD: human epidemiological data indicate that lithium reduces AD risk. Animal model studies (AMS reveal encouraging results for quetiapine, lithium, donepezil, and memantine. Early PD: valproate AMS findings show promise. Pre-symptomatic PD: lithium and valproate AMS findings are encouraging. Early HD: uncontrolled clinical data indicate non-progression with lithium, fluoxetine, donepezil, and memantine. Pre-symptomatic HD: lithium and valproate are auspicious in AMS. Many other promising findings awaiting replication (valproate in MCI; lithium, valproate, fluoxetine in pre-symptomatic AD; lithium in early PD; lithium, valproate, fluoxetine in pre-symptomatic PD; donepezil in early HD; lithium, fluoxetine, memantine in pre-symptomatic HD are reviewed. Dose- and stage-dependent effects are considered. Suggestions for signal-enhancement in human trials are provided for each NDD stage.

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

Painful L5/S1 pseudoarthrosis has been previously managed with posterior excision and/or lumbar fusion. To our knowledge, the anterior approach for L5/S1 pseudoarthrectomy in the treatment of Bertolotti's syndrome has not been described. We present two patients with severe symptomatic L5/S1 pseudoarthroses that were successfully excised via an anterior retroperitoneal approach with 2 year clinical and radiological follow-up. The literature regarding surgical treatments for Bertolotti's syndrome is reviewed. The technique for an anterior retroperitoneal approach is described. This approach has been safe and effective in providing long term symptomatic relief to our two patients. Further studies comparing the outcomes of anterior versus posterior pseudoarthrectomy will guide the management of this condition. Copyright © 2013 Elsevier Ltd. All rights reserved.

Clinicopathological study of asymptomatic gastric cancer and symptomatic gastric cancer

2008-01-01

Gastric cancer can be classified into two categories based on the absence or presence of symptoms at diagnosis. Differences in clinicopathological features and prognoses between asymptomatic gastric cancer (ACG) and symptomatic gastric cancer (SGC) can be used to inform diagnosis strategies and ultimately improve survival rates. All cases of gastric cancer (239 AGC, 323 SGC) diagnosed in our hospital between 1997 and 1999 were used in this study. ACG patients showed significantly higher frequency of males, cases of early cancer, cases found by a mass screening program, cases treated by endoscopic resection, cases treated by curative operation, cases of type 0 macroscopic finding, cases of histologically-differentiated type, and stage I cases. By contrast, SGC patients showed significantly higher numbers of cases treated by chemotherapy alone or best support care, cases of type 2, 3, and 4 macroscopic findings, cases occupying the whole stomach, and cases of stage II, III, IV. Statistically significant differences were also found for the 5-year survival rate (83.3% in AGC, 41.2% in SGC), the incidence of early cancer (90.1% in AGC, 83.7% in SGC), and for advanced cancer (38.7% in AGC, 22.7% in SGC). The higher incidence of advanced cases in SGC than in AGC (40.0% vs. 13.0%), coupled with the low 5-year survival rate of advanced SGC (22.7%), provides strong evidence of the importance of diagnosing gastric cancer during its asymptomatic period.

Neuroform and Enterprise are widely used self-expanding stents designed to treat wide-necked intracranial aneurysms. To assess the incidence, clinical significance, predictors, and outcomes of in-stent stenosis (ISS). Angiographic studies and hospital records were retrospectively reviewed for 435 patients treated between 2005 and 2011 in our institution. A multivariable regression analysis was conducted to determine the predictors of ISS. The Neuroform stent was used in 264 patients (60.7%) and the Enterprise in 171 patients (39.3%). A total of 11 patients (2.5%) demonstrated some degree of ISS during the follow-up period at a mean time point of 4.2 months (range, 2-12 months). The stenosis was mild ( 75%) in 1 patient (0.2%). No patients were symptomatic or required further intervention. There was complete ISS resolution in 2 patients, partial resolution in 2 patients, and no change in 5 patients on follow-up angiography. Patients developing ISS were significantly younger than those without ISS (40.3 vs. 54.9 years; P stent (P = .6). In multivariable analysis, younger patient age (odds ratio = 0.92; P = .008), carotid ophthalmic aneurysm location (odds ratio = 7.7; P =0.01), and carotid terminus aneurysm location (odds ratio = 8.1; P = .009) were strong independent predictors of ISS. The type of stent was not a predictive factor. Neuroform and Enterprise ISS is an uncommon, often transient, and clinically benign complication. Younger patients and those harboring anterior circulation aneurysms located at ophthalmic and carotid terminus locations are more likely to develop ISS.

To determine the effects of therapy with Urtica dioica for symptomatic relief of lower urinary tract symptoms (LUTS) secondary to benign prostatic hyperplasia (BPH). A 6-month, double-blind, placebo-controlled, randomized, partial crossover, comparative trial of Urtica dioica with placebo in 620 patients was conducted. Patients were evaluated using the International Prostate Symptom Score (IPSS), the maximum urinary flow rate (Qmax), postvoid residual urine volume (PVR), Serum Prostatic- Specific Antigen (PSA), testosterone levels, and prostate size. At the end of 6-month trial, unblinding revealed that patients who initially received the placebo were switched to Urtica dioica. Both groups continued the medication up to 18 months. 558 patients (90%) completed the study (287/305, 91% in the Urtica dioica group, and 271/315, 86% in the placebo group). By intention- to-treat analysis, at the end of 6-month trial, 232 (81%) of 287 patients in the Urtica dioica group reported improved LUTS compared with 43 (16%) of 271 patients in the placebo group (P Urtica dioica and from 19.2 to 17.7 with placebo (P = 0.002). Peak flow rates improved by 3.4 mL/s for placebo recipients and by 8.2 mL/s for treated patients (P Urtica dioica group, PVR decreased from an initial value of 73 to 36 mL (P Urtica dioica group (from 40.1 cc initially to 36.3 cc; P Urtica dioica have beneficial effects in the treatment of symptomatic BPH. Further clinical trials should be conducted to confirm these results before concluding that Urtica dioica is effective.

Widespread hypermetabolism in symptomatic and asymptomatic episodes in Kleine-Levin syndrome.

Directory of Open Access Journals (Sweden)

Yves Dauvilliers

Full Text Available BACKGROUND: No reliable biomarkers are identified in KLS. However, few functional neuroimaging studies suggested hypoactivity in thalamic and hypothalamic regions during symptomatic episodes. Here, we investigated relative changes in regional brain metabolism in Kleine-Levin syndrome (KLS during symptomatic episodes and asymptomatic periods, as compared to healthy controls. METHODS: Four drug-free male patients with typical KLS and 15 healthy controls were included. 18-F-fluorodeoxy glucose positron emission tomography (PET was obtained in baseline condition in all participants, and during symptomatic episodes in KLS patients. All participants were asked to remain fully awake during the whole PET procedure. RESULTS: Between state-comparisons in KLS disclosed higher metabolism in paracentral, precentral, and postcentral areas, supplementary motor area, medial frontal gyrus, thalamus and putamen during symptomatic episodes, and decreased metabolism in occipital and temporal gyri. As compared to healthy control subjects, KLS patients in the asymptomatic phase consistently exhibited significant hypermetabolism in a wide cortical network including frontal and temporal cortices, posterior cingulate and precuneus, with no detected hypometabolism. In symptomatic KLS episodes, hypermetabolism was additionally found in orbital frontal and supplementary motor areas, insula and inferior parietal areas, and right caudate nucleus, and hypometabolism in the middle occipital gyrus and inferior parietal areas. CONCLUSION: Our results demonstrated significant hypermetabolism and few hypometabolism in specific but widespread brain regions in drug-free KLS patients at baseline and during symptomatic episodes, highlighting the behavioral state-dependent nature of changes in regional brain activity in KLS.

Benign fibroosseous lesions

2016-05-01

Full Text Available Benign fibroosseous lesions represent a group of lesions that share the same basic evolutive mechanism and are characterized by replacement of normal bone with a fibrous connective tissue that gradually undergoes mineralization. These lesions are presented by a variety of diseases including developmental, reactive-dysplastic processes and neoplasms. Depending on the nature and amount of calcified tissue, they can be observed as radiolucent, mixed or radiopaque. Their radiographic features could be well-defined or indistinguishable from the surrounding bone tissue. They can be asymptomatic as in osseous dysplasias and can be detected incidentally on radiographs, or they can lead to expansion in the affected bone as in ossifying fibroma. All fibroosseous lesions seen in the jaws and face are variations of the same histological pattern. Therefore, detailed clinical and radiographic evaluation in differential diagnosis is important. In this review, fibroosseous benign lesions are classified as osseous dysplasia, fibrous dysplasia and fibroosseous tumors; and radiographic features and differential diagnosis of these lesions are reviewed taking into account this classification.

Angiomyolipomas are the most common type of benign renal tumors and are characterized by a mixture of mature adipose tissue, sheet of smooth muscle, and thick-walled blood vessels of various proportions. Several cases of angiomyolipoma with partial malignant transformation invading the adjacent structure and lymph node have been reported. On the other hand, benign angiomyolipomas invading the adjacent structures has been rarely reported. We report a case of a benign angiomyolipoma with renal vein invasion

Defence in depth in nuclear safety learning from 'pre-symptomatic diseases'

Traditional Chinese medicine argued 'pre-symptomatic diseases', which encouraged for a physician to treat before the ailment occurred. This article described such prophylactic concept was compared to that of defense in depth in nuclear safety, which suggested encouragement of daily activities with safety awareness, preventive maintenance and appropriate treatment for incidents of aged plants would reduce or mitigate their effects. Area of safety culture was also included. Importance of human resources development for safety culture and need of establishment of database concerning new knowledge and experiences were highly recommended. In reality various slight events, whose level of the International Nuclear Event Scale (INES) were less than 2, occurred before a large accident happened to occur. Efforts to reduce events whose level of INES was less than 2 or precursor of accidents would prevent level 3 serious accidents as maximum accident of defense in depth or mitigate the extension to a larger accident.

1992-01-01

Fifteen patients with 38 compression fractures of the spine underwent magnetic resonance(MR) imaging. We retrospectively evaluated MR images in those benign compression fractures. MR images showed four patterns in T1-weighted images. MR imaging patterns were normal signal(21), band like low signal(8), low signal with preservation of peripheral portion of the body(8), and diffuse low signal through the vertebral body(1). The low signal portions were changed to high signal intensities in T2-weighted images. In 7 of 15 patients (11 compression fractures), there was a history of trauma, and the remaining 8 patients (27 compression fractures) had no history of trauma. Benign compression fractures of trauma, remained 8 patients (27 compression fractures) were non-traumatic. Benign compression fractures of the spine reveal variable signal intensities in MR imagings. These patterns of benign compression fractures may be useful in interpretation of MR imagings of the spine

The purpose of this study was to investigate the utility of diffusion-weighted imaging (DWI) and the apparent diffusion coefficient (ADC) value in differentiating benign and malignant breast lesions and evaluating the detection accuracy of the cancer extension. We used DWI to obtain images of 191 benign and malignant lesions (24 benign, 167 malignant) before surgical excision. The ADC values of the benign and malignant lesions were compared, as were the values of noninvasive ductal carcinoma (NIDC) and invasive ductal carcinoma (IDC). We also evaluated the ADC map, which represents the distribution of ADC values, and compared it with the cancer extension. The mean ADC value of each type of lesion was as follows: malignant lesions, 1.22±0.31 x 10 -3 mm 2 /s; benign lesions, 1.67±0.54 x 10 -3 mm 2 /s; normal tissues, 2.09±0.27 x 10 -3 mm 2 /s. The mean ADC value of the malignant lesions was statistically lower than that of the benign lesions and normal breast tissues. The ADC value of IDC was statistically lower than that of NIDC. The sensitivity of the ADC value for malignant lesions with a threshold of less than 1.6 x 10 -3 mm 2 /s was 95% and the specificity was 46%. A full 75% of all malignant cases exhibited a near precise distribution of low ADC values on ADC maps to describe malignant lesions. The main causes of false negative and underestimation of cancer spread were susceptibility artifact because of bleeding and tumor structure. Major histologic types of false-positive lesions were intraductal papilloma and fibrocystic diseases. Fibrocystic diseases also resulted in overestimation of cancer extension. DWI has the potential in clinical appreciation to detect malignant breast tumors and support the evaluation of tumor extension. However, the benign proliferative change remains to be studied as it mimics the malignant phenomenon on the ADC map. (author)

the term prostatic hyperplasia is most frequently used to describe the benign prostatic growth, this being a widely prevalent disorder associated with age that affects most men as they age. The association between prostate growth and urinary obstruction in older adults is well documented. large benign prostatic hyperplasia is rare and few cases have been published and should be taken into account during the study of tumors of the pelvic cavity. we report the case of an 81-year-old who had significant symptoms relating to storage and bladder emptying, with no significant elevation of prostate specific antigen. this is a rare condition but it is still important to diagnose and treat as it may be related to severe obstructive uropathy and chronic renal failure. In our institution, cases of large prostatic hyperplasia that are solved by suprapubic adenomectomy are less than 3%.

Purpose: To evaluate the safety and outcome of ovarian artery embolization (OAE) in patients with collateral supply to symptomatic uterine leiomyomata. Materials and Methods: Thirteen patients with relevant leiomyoma perfusion by way of enlarged ovarian arteries underwent additional OAE during the same (N = 10) or a second procedure (N = 3). Uterine artery embolization (UAE) was performed bilaterally in 10 and unilaterally in 2 patients with a single artery. One patient had no typical uterine arteries but bilaterally enlarged ovarian arteries, prompting bilateral OAE. OAE was accomplished with coil embolization in one and particle embolization in 12 patients. Symptoms before therapy and clinical outcome were assessed using a standardized questionnaire. Contrast-enhanced magnetic resonance (MR) imaging after embolization was available in 11 of 13 patients and was used to determine the percentage of fibroid infarction. Results: UAE and OAE were technically successful in all patients. One patient experienced prolonged irritation at the puncture site. Median clinical follow-up time was 16 months (range 4–37). Ten of 13 patients showed improvement or complete resolution of clinical symptoms. One patient reported only slight improvement of her symptoms. These women presented with regular menses. Two patients (15%), 47 and 48 years, both with unilateral OAE, reported permanent amenorrhea directly after embolization. Their symptoms completely resolved. Seven patients showed complete and 4 showed >90% fibroid infarction after embolization therapy. Conclusions: OAE is technically safe and effective in patients with ovarian artery collateral supply to symptomatic uterine leiomyomata. The risk of permanent amenorrhea observed in this study is similar to the reported incidence after UAE.

The present study aimed to assess the efficacy and indications of surgical laser therapy in the treatment of oral soft tissues benign tumors compared to classic surgery. A controlled clinical study was conducted in a group of 93 patients presenting various forms of oral soft tissues benign tumors. These patients were examined pre-and postoperatively and the oral benign tumors were measured linearly and photographed. The surgery of laser-assisted biopsy excision of oral benign tumors was carried out using a diode laser device of 980 nm. In patients who received surgical laser treatment, therapeutic doses of laser to biostimulate the operated area were administered on the first day after the surgery. The interventions of conventional excision of oral soft tissues benign tumors consisted in removing them using scalpel. In patients who have received therapeutic doses of laser for biostimulation of the operated area, a faster healing of wound surfaces and tumor bed was observed during the first days after surgery. Two weeks after the surgical treatment, good healing without scarring or discomfort in the area of excision was documented. Surgical treatment of oral soft tissues benign tumors with laser assisted postoperative therapy confirms the benefits of this surgical procedure. A faster healing process of the excision area due to laser biostimulation of low intensity has been observed in patients with surgical laser assisted treatment in the postoperative period.

Benign childhood epilepsy with occipital paroxysms is classified among childhood benign partial epilepsies. The absence of neurological and neuropsychological deficits has long been considered as a prerequisite for a diagnosis of benign childhood partial epilepsy. Much evidence has been reported in literature in the latest years suggesting a neuropsychological impairment in this type of epilepsy, particularly in the type with Rolandic paroxysms. The present work examines the neuropsychological profiles of a sample of subjects affected by the early-onset benign childhood occipital seizures (EBOS) described by Panayotopulos. The patient group included 22 children (14 males and 8 females; mean age 10.1+/-3.3 years) diagnosed as having EBOS. The patients were examined with a set of tests investigating neuropsychological functions: memory, attention, perceptive, motor, linguistic and academic (reading, writing, arithmetic) abilities. The same instruments have been given to a homogeneous control group as regards sex, age, level of education and socio-economic background. None of the subjects affected by EBOS showed intellectual deficit (mean IQ in Wechsler Full Scale 91.7; S.D. 8.9). Results show a widespread cognitive dysfunction in the context of a focal epileptogenic process in EBOS. In particular, children with EBOS show a significant occurrence of specific learning disabilities (SLD) and other subtle neuropsychological deficits. We found selective dysfunctions relating to perceptive-visual attentional ability (pmemory abilities (psupports the hypothesis that epilepsy itself plays a role in the development of neuropsychological impairment. Supported by other studies that have documented subtle neuropsychological deficits in benign partial epilepsy, we stress the importance of reconsidering its supposed "cognitive benignity", particularly in occipital types.

Lung adenocarcinoma can easily cause malignant pleural effusion which was difficult to discriminate from benign pleural effusion. Now there was no biomarker with high sensitivity and specificity for the malignant pleural effusion. This study used proteomics technology to acquire and analyze the protein profiles of the benign and malignant pleural effusion, to seek useful protein biomarkers with diagnostic value and to establish the diagnostic model. We chose the weak cationic-exchanger magnetic bead (WCX-MB) to purify peptides in the pleural effusion, used matrix-assisted laser desorption/ionization time-of-flight mass spectrometry (MALDI-TOF-MS) to obtain peptide expression profiles from the benign and malignant pleural effusion samples, established and validated the diagnostic model through a genetic algorithm (GA) and finally identified the most promising protein biomarker. A GA diagnostic model was established with spectra of 3930.9 and 2942.8 m/z in the training set including 25 malignant pleural effusion and 26 benign pleural effusion samples, yielding both 100 % sensitivity and 100 % specificity. The accuracy of diagnostic prediction was validated in the independent testing set with 58 malignant pleural effusion and 34 benign pleural effusion samples. Blind evaluation was as follows: the sensitivity was 89.6 %, specificity 88.2 %, PPV 92.8 %, NPV 83.3 % and accuracy 89.1 % in the independent testing set. The most promising peptide biomarker was identified successfully: Isoform 1 of caspase recruitment domain-containing protein 9 (CARD9), with 3930.9 m/z, was decreased in the malignant pleural effusion. This model is suitable to discriminate benign and malignant pleural effusion and CARD9 can be used as a new peptide biomarker.

To evaluate the efficacy of vault drainage in reducing the immediate postoperative morbidity associated with vaginal hysterectomy carried out for benign gynaecological conditions. Randomised controlled trial. A tertiary referral gynaecology centre in UK. A total of 272 women who underwent vaginal hysterectomy for benign conditions between March 2005 and June 2010. The 272 women were randomised to have a drain inserted or not inserted, 'drain' or 'no drain', respectively, before vault closure during vaginal hysterectomy, using a sealed envelope technique. The surgical procedures were performed using the surgeons' standard technique and postoperative care was delivered according to the unit's protocol. The primary outcome measure was reduction in postoperative febrile morbidity. Secondary outcome measures were hospital readmission rate, blood transfusion, change in postoperative haemoglobin and length of stay. In all, 135 women were randomised to have a drain and 137 to 'no drain'. There were no differences in the incidence of febrile morbidity, length of stay, change in haemoglobin or need for postoperative blood transfusion between the two groups. The routine use of vault drain at vaginal hysterectomy for benign disorders has no significant effect on postoperative morbidity. The use of vault drain in this context is not recommended. © 2011 The Authors BJOG An International Journal of Obstetrics and Gynaecology © 2011 RCOG.

Full Text Available The aims of this study were to determine the incidence of the filarial avian nematode Serratospiculum seurati in falcons from Kuwait, report clinical signs and find an effective therapy. Naturally occurring S. seurati infestation was diagnosed in 149 (8.7 % out of 1,706 captive falcons examined between May 2003 and April 2005, and 140 of these were treated with melarsomine at dosage of 0.25 mg/kg injected intramuscularly for two days, and ivermectin, injected once at the dose of 1 mg/kg, 10 days later. Infestation was reportedly symptomatic in 107 (71.8 % and non-symptomatic in 42 (28.2 % falcons. Signs reported more often were dyspnoea (58.8 %, reduced speed and strength in flight (56 %, weight loss (38.3 %, anorexia/poor appetite (22.4 % and lethargy (16.8 %. After administration of melarsomine, signs disappeared within 1-10 days in symptomatic birds and improvement of flight performances was noted in non-symptomatic birds. Dead adult parasites were ejected in 22 cases. Embryonated eggs were not detected in coproscopic checks made 10 and 40 days after the end of therapy, in association with lasting clinical remission. The main conclusion is that Serratospiculum seurati is overall pathogenic for birds of prey in the Middle East and that melarsomine + ivermectin can be an effective protocol of therapy eliminating both clinical signs and parasites.

The purpose of this study was to determine the prevalence of cuff tear and acromioclavicular joint (ACJ) osteoarthrosis by magnetic resonance imaging (MRI) evaluation in symptomatic shoulders. MRI was performed on 124 shoulders in 115 patients whose age ranged from 16 to 83 years (average: 58.0 years). There were 74 men (79 shoulders) and 41 women (45 shoulders). The patients were divided into three groups according to age; A group (10 shoulders: 16-29 years), B group (43 shoulders: 30-59 years), and C group (71 shoulders: 60-83 years). Rotator cuff tears and ACJ osteoarthrosis were graded on scales 0 to 3 (normal, increased signal intensity, incomplete, complete), and 1 to 4 (none, mild, moderate, severe), respectively. There was a significant difference in the severity of the cuff tears and the ACJ osteoarthrosis with respect to age. Twenty percent of the shoulders were graded incomplete or complete cuff tears in group A, 88% in group B, and 93% in group C. No shoulders were graded moderate or severe ACJ changes in group A, 63% in group B, and 93% in group C. There was a definite correlation between the cuff tears and ACJ osteoarthrosis. MRI of the symptomatic shoulders indicated well correlation between the rotator cuff tears and ACJ osteoarthrosis. (author)

The spleen is one of the largest organ in the reticuloendothelial system and plays an important role in the activation of immune response. It is the organ most commonly injured after blunt abdominal trauma, and malignant lesions such as lymphoma, or these due to metastasis, occur not infrequently. Even so, it is ignored even in abdominal ultrasonography. Some benign splenic lesions, however can cause severe symptoms and result in high mortality, and their accurate diagnosis is therefore essential. This study describes the imaging findings and histopathologic features of various nontraumatic benign splenic lesions.

Benign metastatic leiomyoma (BML) is an extremely rare disease. Although uterine leiomyomas are benign histologically, they can metastasize to distant sites. While the incidence is very low, the lung is the organ most frequently affected by BML. Pulmonary BML usually presents as numerous well-defined nodules of various sizes, while the cavitary or cystic features in the nodules are rarely observed on radiologic images. A 52-year-old woman complained of cough and dyspnea for one month. She had been previously diagnosed with uterine leiomyoma and had undergone total hysterectomy about 14 years prior. High-resolution computed tomography (CT) images showed that there were multiple cystic nodules of various sizes in both lungs. Pathologic examination revealed that the pulmonary nodule had complex branching glandular structures lined by a single layer of simple cuboidal to columnar epithelium that was surrounded by abundant spindle cells. Additional immunohistochemistry data suggested that pulmonary nodule diagnosis was BML-associated uterine leiomyoma. In this report, we introduce an interesting case of pulmonary BML that presented as a combination of various kinds of nodules including simple round nodules, simple cysts, and cysts with a solid portion, which are very rare radiologic features of BML in lung. In addition, when the patient is a woman of reproductive age, physicians should meticulously review the gynecological history and suspect BML when there are various cystic pulmonary lesions.

Inverted papillomas and benign nonneoplastic lesions of the nasal cavity

Casiano, Roy R.

2012-01-01

Background: Benign lesions of the nasal cavity represent a diverse group of pathologies. Furthermore, each of these disorders may present differently in any given patient as pain and discomfort, epistaxis, headaches, vision changes, or nasal obstruction. Although these nasal masses are benign, many of them have a significant capacity for local tissue destruction and symptomatology secondary to this destruction. Advances in office-based endoscopic nasendoscopy have equipped the otolaryngologist with a safe, inexpensive, and rapid means of directly visualizing lesions within the nasal cavity and the initiation of appropriate treatment. Methods: The purpose of this study is to review the diagnosis, management, and controversies of many of the most common benign lesions of the nasal cavity encountered by the primary care physician or otolaryngologist. Results: This includes discussion of inverted papilloma (IP), juvenile angiofibroma, squamous papilloma, pyogenic granuloma, hereditary hemorrhagic telangiectasia, schwannoma, benign fibro-osseous lesions, and other benign lesions of the nasal cavity, with particular emphasis on IP and juvenile angiofibroma. Conclusion: A diverse array of benign lesions occur within the nasal cavity and paranasal cavities. Despite their inability to metastasize, many of these lesions have significant capability for local tissue destruction and recurrence. PMID:22487294

We aimed to assess the prevalence, incidence, age-of-onset and diagnostic stability of threshold and subthreshold anorexia nervosa (AN) and bulimia nervosa (BN) in the community. Data come from a prospective-longitudinal community study of 3021 subjects aged 14-24 at baseline, who were followed up at three assessment waves over 10 years. Eating disorder (ED) symptomatology was assessed with the DSM-IV/M-CIDI at each wave. Diagnostic stability was defined as the proportion of individuals still affected with at least symptomatic eating disorders (EDs) at follow-ups. Baseline lifetime prevalence for any threshold ED were 2.9 % among females and 0.1 % among males. For any subthreshold ED lifetime prevalence were 2.2 % for females and 0.7 % for males. Symptomatic expressions of EDs (including core symptoms of the respective disorder) were most common with a lifetime prevalence of 11.5 % among females and 1.8 % among males. Symptomatic AN showed the earliest onset with a considerable proportion of cases emerging in childhood. 47 % of initial threshold AN cases and 42 % of initial threshold BN cases showed at least symptomatic expressions of any ED at any follow-up assessment. Stability for subthreshold EDs and symptomatic expressions was 14-36 %. While threshold EDs are rare, ED symptomatology is common particularly in female adolescents and young women. Especially threshold EDs are associated with a substantial risk for stability. A considerable degree of symptom fluctuation is characteristic especially for subthreshold EDs.

Spinal Subdural Abscess Following Laminectomy for Symptomatic Stenosis: A Report of 2 Cases and Review of the Literature.

BACKGROUND Spinal subdural abscesses, also known as empyemas, are rare infectious lesions, the exact incidence of which is unknown. Presentation is typically dramatic, with back pain, fever, motor, and sensory deficits. Rapid identification and surgical intervention with laminectomy, durotomy, and washout provides the best outcomes. While hematogenous spread of an extra-spinal infection is the most common cause of this condition, a significant number of cases result from iatrogenic mechanisms, including lumbar punctures, epidural injections, and surgery. CASE REPORT Here we present 2 cases: 1) an 87-year-old man with type 2 diabetes, schizophrenia, mild cognitive impairment, and symptomatic lumbar spinal stenosis and 2) a 62-year-old man with a prior L3-4 spinal fusion with symptomatic lumbar spinal stenosis. In both cases, patients underwent laminectomy for spinal stenosis and developed epidural abscess. Following successful drainage of the epidural abscess, they continued to be symptomatic, and repeat imaging revealed the presence of a subdural abscess that was subsequently evacuated. Case 1 had significant improvement with residual lower-extremity weakness, while Case 2 made a complete neurological recovery. CONCLUSIONS These cases illustrate patients at increased risk for developing this rare spinal infection, and demonstrate that rapid recognition and surgical treatment is key to cure and recovery. Review of the literature highlights pertinent risk factors and demonstrates nearly one-third of reported cases have an iatrogenic etiology. The cases presented here demonstrate that a subdural process should be suspected in any patient with intractable pain following treatment of an epidural abscess.

Analysis of an HIV/AIDS treatment model with a nonlinear incidence

2009-01-01

An HIV/AIDS treatment model with a nonlinear incidence is formulated. The infectious period is partitioned into the asymptotic and the symptomatic phases according to clinical stages. The constant recruitment rate, disease-induced death, drug therapies, as well as a nonlinear incidence, are incorporated into the model. The basic reproduction number R 0 of the model is determined by the method of next generation matrix. Mathematical analysis establishes that the global dynamics of the spread of the HIV infectious disease are completely determined by the basic reproduction number R 0 . If R 0 ≤1, the disease always dies out and the disease-free equilibrium is globally stable. If R 0 >1, the disease persists and the unique endemic equilibrium is globally asymptotically stable in the interior of the feasible region.

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

Many physicians remain uncertain about prescribing hormone therapy for symptomatic women at the onset of menopause. The American Society for Reproductive Medicine (ASRM) convened a multidisciplinary group of healthcare providers to discuss the efficacy and risks of hormone therapy for symptomatic women, and to determine whether it would be appropriate to treat women at the onset of menopause who were complaining of menopausal symptoms. Numerous controlled clinical trials consistently demonstrate that hormone therapy, administered via oral, transdermal, or vaginal routes, is the most effective treatment for vasomotor symptoms. Topical vaginal formulations of hormone therapy should be preferred when prescribing solely for the treatment of symptoms of vulvar and vaginal atrophy. Data from the Women's Health Initiative indicate that the overall attributable risk of invasive breast cancer in women receiving estrogen plus progestin was 8 more cases per 10,000 women-years. No increased risk for invasive breast cancer was detected for women who never used hormone therapy in the past or for those receiving estrogen only. Hormone therapy is not effective for the treatment of cardiovascular disease and that the risk of cardiovascular disease with hormone therapy is principally in older women who are considerably postmenopause. Healthy symptomatic women should be offered the option of hormone therapy for menopausal symptoms. Symptom relief with hormone therapy for many younger women (at the onset of menopause) with menopausal symptoms outweighs the risks and may provide an overall improvement in quality of life. Hormone therapy should be individualized for symptomatic women. This involves tailoring the regimen and dose to individual needs.

To determine whether radiofrequency thermal ablation can be used to treat benign cystic lesions in a porcine gallbladder model. This experimental study of radiofrequency thermal ablation involved the use of 15 exvivo porcine gallbladders and 15-G expandable needle electrodes. To investigate optimal temperature parameters, three groups of five were designated according to target temperature:Group A: 70 deg C; Group B: 80 deg C; Group C: 90 deg C. After the target temperature was reached, ablation lasted for one minute. Gallbladder width, height and length were measured before and after ablation , and the estimated volume reduction ratios of the three groups were compared. Whether adjacent liver parenchyma around the gallbladder fossa was ablated by heat conducted from hot bile was also determined, and the thickness of the ablated area of the liver was measured. The volume reduction ratio in Group A, B and C was 42.7%, 41.7% and 42.9%, respectively (ρ>.05). In all 15 cases, gallbladder walls lost their transparency and elasticity at about 70 deg C. In nine of ten cases in Groups B and C, the hepatic capsule around the gallbladder fossa was retracted at about 80 deg C. The mean thickness of liver parenchymal damage adjacent to the gallbladder was 5.4 mm in Group B and 9.8 mm in Group C. In Group A livers, only one case showed minimal gradual parenchymal change. Microscopically, all three groups showed complete coagulation necrosis of the wall. On the basis of this feasibility study, radiofrequency thermal ablation is potentially suitable for the ultrasound-guided treatment of symptomatic cystic lesions including benign hepatic or renal cyst

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.

Contrast-enhanced MR imaging of the spine after surgery for lumbar disk herniation almost always shows pathologic changes. To investigate to what extent these changes are correlated to patients' actual clinical symptoms, we compared the postoperative MR findings in 19 asymptomatic patients with 42 symptomatic patients (43 levels). The asymptomatic patients underwent MR examination one year after surgery. Twenty-six of the symptomatic patients underwent MR one year of less after surgery, and in 16 patients (17 levels) MR was performed more than one year after surgery. Sixteen percent of the asymptomatic and 42% of the symptomatic patients had disk herniation at the level of previous surgery. Most of the herniated disks were found in the symptomatic patients less than one year after surgery. The amount of epidural scar tissue, displacement and thickening of nerve roots, and compression of the dural sac were also studied. Disk herniation as a probable cause of recurrent sciatica was a common finding among symptomatic patients examined one year or less after surgery. In comparing asymptomatic patients and symptomatic patients with more than one year between surgery and MR examination, no significant radiologic differences, including disk herniation, were found.

The asymptomatic patients underwent MR examination one year after surgery. Twenty-six of the symptomatic patients underwent MR one year of less after surgery, and in 16 patients (17 levels) MR was performed more than one year after surgery. Sixteen percent of the asymptomatic and 42% of the symptomatic patients had disk herniation at the level of previous surgery. Most of the herniated disks were found in the symptomatic patients less than one year after surgery. The amount of epidural scar tissue, displacement and thickening of nerve roots, and compression of the dural sac were also studied. Disk herniation as a probable cause of recurrent sciatica was a common finding among symptomatic patients examined one year or less after surgery. In comparing asymptomatic patients and symptomatic patients with more than one year between surgery and MR examination, no significant radiologic differences, including disk herniation, were found.

Focal lesions of the liver often have various imaging characteristics which may be interpreted as either benign or malignant. Understanding the underlying pathophysiology of these liver lesions may lead to characteristic imaging manifestations, which direct the radiologist to the diagnosis. Benign lesions include congenital hepatic cyst, autosomal dominant polycystic disease, hemangioma, focal nodular hyperplasia (FNH), hepatic adenoma, inflammatory pseudotumor, peliosis hepatis, focal fatty infiltration, hamartoma, and infectious processes such as hepatic abscess, echinococcal cyst, and candidiasis. Characteristic imaging features, clinical symptoms, and treatment/prognosis will be discussed. Emphasis will be placed on key reliable features of each disease to develop a method of discriminating these lesions from other benign and malignant disorders.

Full Text Available Hee Ju Cho, Tag Keun Yoo Department of Urology, Eulji Hospital, Eulji University School of Medicine, Seoul, KoreaAbstract: α1-Adrenergic receptor antagonists are commonly used to treat male lower urinary tract symptoms and benign prostatic hyperplasia (BPH. We performed a literature search using PubMed, Medline via Ovid, Embase, and the Cochrane Library databases to identify studies on the treatment of BPH by silodosin. Silodosin is a novel α1-adrenergic receptor antagonist whose affinity for the α1A-adrenergic receptor is greater than that for the α1B-adrenergic receptor. Therefore, silodosin does not increase the incidence of blood pressure-related side effects, which may result from the inhibition of the α1B-adrenergic receptor. Patients receiving silodosin at a daily dose of 8 mg showed a significant improvement in the International Prostate Symptom Score and maximum urinary flow rate compared with those receiving a placebo. Silodosin also improved both storage and voiding symptoms, indicating that silodosin is effective, even during early phases of BPH treatment. Follow-up extension studies performed in the United States, Europe, and Asia demonstrated its long-term safety and efficacy. In the European study, silodosin significantly reduced nocturia compared to the placebo. Although retrograde or abnormal ejaculation was the most commonly reported symptom in these studies, only a few patients discontinued treatment. The incidence of adverse cardiovascular events was also very low. Evidence showing solid efficacy and cardiovascular safety profiles of silodosin will provide a good solution for the treatment of lower urinary tract symptoms associated with BPH in an increasingly aging society.

Compare safety and tolerability of the Prolieve(®) System with the Targis(®) System using objective and subjective measures. Thirty-four men with symptomatic benign prostatic hyperplasia (BPH) were randomized to a single treatment with either the Prolieve or Targis system; 30 were treated and then followed for 6 months. After post-treatment bladder fill with ≥200 mL saline, patients were catheterized if they could not void after 2 hours or had a postvoid residual >150 mL. Catheter use, visual analog scale (VAS) tolerability scores, American Urological Association scores, and safety were assessed. After treatment, 15/16 (94%) Prolieve patients remained catheter-free compared with 3/14 (21%) Targis patients (P = 0.0001). Foley catheter indwelling time was 58.8 hours for the one Prolieve patient compared with 103.9 hrs (range 54-270 h) for the Targis patients (n = 9). Targis patients' catheterization requirements were: Seven Foley only, two intermittent self-catheters only, and two needing both. Intermittent self-catheterization continued for 1 month in two Targis patients. VAS tolerability scores were 24% to 50% lower during Prolieve treatment vs Targis (P 0.05). Overall, the incidence of device-related adverse events was 31% (Prolieve) compared with 64% (Targis) (P > 0.05)-most prevalently, urinary retention, dysuria, and hematuria. No device-related serious adverse events occurred. Prolieve provided enhanced near-term therapeutic benefit over Targis as assessed by catheterization, tolerability, and symptom relief, which may assist physician and patient decision-making when selecting an office-based transurethral microwave therapy option for patients.

Bin Chet Toh

Full Text Available Introduction: Gastric volvulus is a surgical condition that should be recognised promptly to prevent life-threatening gastric ischaemia and perforation in acute setting. There are two peak age group of incidence with children less than one year old and at fifth decade.1 The mortality rates for acute gastric volvulus remain high with reported range from 30% to 50% signifying the need of early diagnosis and treatment.2 These case series reported modified minimal invasive approach for symptomatic chronic gastric volvulus in a tertiary upper gastrointestinal unit in Singapore. Methods: Retrospective case series reviewed in single centre from 1st May 2016 to 1st May 2017 of clinical outcomes of modified minimally invasive approach and de-rotation of symptomatic chronic gastric volvulus. Results: Three symptomatic patients with evidence of gastric volvulus on CT-scan underwent minimally invasive repair with the aids of GastriSail™ Gastric positioning system. GastriSail™ was used for gastric volvulus de-rotation prior to repair definitely. Two patients had fundoplication done and one patient had gastropexy performed successfully. All patients started on blended diet post-operative day 1 and discharged well. Patient remained asymptomatic and nil recurrence at 3 months follow-up post-operation. Conclusion: Based on our experience, we advocate modified minimally invasive repair of chronic gastric volvulus as an alternative to traditional open surgical technique with acceptable good clinical outcomes.

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.

Optimization of coronary risk evaluation in stroke patients has been encouraged. The relationship between symptomatic intracranial atherosclerosis and occult coronary artery disease (CAD) has not been evaluated sufficiently. We aimed to investigate the prevalence of silent myocardial ischemia in patients with symptomatic intracranial atherosclerosis and to identify factors associated with its presence. From 186 first-ever transient ischemic attack or ischemic stroke patients with intracranial stenoses, 65 fulfilled selection criteria, including angiographic confirmation of a symptomatic atherosclerotic stenosis and absence of known CAD. All patients underwent a maximal-stress myocardial perfusion single-photon emission computed tomography (SPECT). Lipoprotein(a) [Lp(a)], C-reactive protein, and homocysteine (Hcy) levels were determined before SPECT. Stress-rest SPECT detected reversible myocardial perfusion defects in 34 (52%) patients. Vascular risk factors associated with a pathologic SPECT were hypercholesterolemia (P=0.045), presence of >2 risk factors (P=0.004) and high Lp(a) (P=0.023) and Hcy levels (P=0.018). Ninety percent of patients with high Lp(a) and Hcy levels had a positive SPECT. Existence of a stenosed intracranial internal carotid artery (ICA; odds ratio [OR], 7.22, 2.07 to 25.23; P=0.002) and location of the symptomatic stenosis in vertebrobasilar arteries (OR, 4.89, 1.19 to 20.12; P=0.027) were independently associated with silent myocardial ischemia after adjustment by age, sex, and risk factors. More than 50% of the patients with symptomatic intracranial atherosclerosis and not overt CAD show myocardial perfusion defects on stress-rest SPECT. Stenosed intracranial ICA, symptomatic vertebrobasilar stenosis and presence of high Lp(a) and Hcy levels may characterize the patients at a higher risk for occult CAD.

The study was carried out from January 1998 to December 1998, among patients with enlarged cervical lymph nodes who were scanned with a high frequency (5.0 MHz curvilinear probe. Chi-Square test was done to see the statistical correlation between two groups of nodes. A p value of <0.05 was taken as significant. Out of 65 nodes studied, 26 (100% enlarged cervical nodes with short axis diameter more than 1 cm were all malignant. In contrast 31 (79.5% of 39 enlarged nodes with short axis diameter less than 1cm were benign and rest were malignant (p<0.001. Of 34 enlarged nodes with L/S ratio <2, 30 (88.2% nodes were found malignant and 4 (11.8% were benign. Among the rest 31 enlarged nodes, 27 (87.1% with L/S ratio  2 were benign while 4 (12.9% were malignant (p <0.001. Among the 39 nodes with regular margin 28 (71.8% were found benign, where as among 26 nodes with irregular margin 23 (88.5% were malignant (p <0.001. When the internal echopattern was taken in account, 32 nodes had homogeneous hypoechoic echo of which 28 (87.5% were benign and among 33 nodes with heterogeneous echopattern 30 (90.9% were malignant (p <0.001. Among the 43 enlarged nodes with presence of hilar echogenicity 31(72.1% were found benign and 22 (100% nodes with no hilar echogenicity were all malignant (p <0.001. Such findings suggest that real time high resolution ultrasound might assist in differentiation of benign and malignant enlarged cervical lymph nodes

Ulipristal acetate in the management of symptomatic uterine fibroids: facts and pending issues.

Science.gov (United States)

Pérez-López, F R

2015-04-01

Various treatment options have been proposed for the management of human symptomatic uterine fibroids (or myomas). Despite this, the most popular one is surgery (myomectomy or hysterectomy). Ulipristal acetate (UA) is a selective progesterone receptor modulator. In women programmed for surgical treatment for uterine fibroids, oral UA treatment (5 or 10 mg/day) controls symptoms, reduces tumor size and improves quality of life as compared to placebo and is not inferior to monthly intramuscular injection of leuprolide acetate for 3 months. Women treated with up to 4 courses of UA (10 mg/day for 3 months) followed or not by norethisterone acetate (10 mg/day for 10 days or placebo) reported a high rate of bleeding control, and improved quality of life, pain anxiety and depression. Median fibroid volume after successive courses of UA treatment ranged from -63% to -72% as compared to baseline value. Endometrium showed benign histological changes without hyperplasia, while adverse events were mild or moderate throughout the several courses of treatment. There is a need for global cost assessment of UA treatment for uterine fibroids, including those women that do not reach their expected outcome and need other complementary explorations or treatments. Studies are needed in non-Caucasian women, in infertile patients and in cases of fibroids associated with adenomyosis. Furthermore, assessment of long-term UA treatment should include endometrial, cardiocirculatory and neurological endpoints.

Full Text Available Benign joint hypermobility syndrome (BJHS, commonly known as loose ligament syndrome, is a non-inflammatory rheumatic condition. It is characterised by a greater than normal range of motion of the joints of the limbs and spine. The prevalence of the syndrome in preschool-age children is estimated to be between 2% and 30%, depending on ethnic background (with higher prevalence in Asian and African populations, occurring most often in families with a history of the condition and more frequently in girls. This paper presents a case report of a 12-year-old girl. A broad differential diagnostic approach to recurrent joint inflammation with joint effusion and pain made it possible to establish a diagnosis of benign joint hypermobility syndrome. The child met the Brighton criteria; her Beighton score was 7 out of 9. Patient education aimed at eliminating abnormal joint movement and an appropriate rehabilitation programme play key roles in the treatment of BJHS.

Anastomotic Strictures after Esophageal Atresia Repair: Incidence, Investigations, and Management, Including Treatment of Refractory and Recurrent Strictures

Directory of Open Access Journals (Sweden)

Renato Tambucci

2017-05-01

Full Text Available Improved surgical techniques, as well as preoperative and postoperative care, have dramatically changed survival of children with esophageal atresia (EA over the last decades. Nowadays, we are increasingly seeing EA patients experiencing significant short- and long-term gastrointestinal morbidities. Anastomotic stricture (AS is the most common complication following operative repair. An esophageal stricture is defined as an intrinsic luminal narrowing in a clinically symptomatic patient, but no symptoms are sensitive or specific enough to diagnose an AS. This review aims to provide a comprehensive view of AS in EA children. Given the lack of evidence-based data, we critically analyzed significant studies on children and adults, including comments on benign strictures with other etiologies. Despite there is no consensus about the goal of the luminal diameter based on the patient’s age, esophageal contrast study, and/or endoscopy are recommended to assess the degree of the narrowing. A high variability in incidence of ASs is reported in literature, depending on different definitions of AS and on a great number of pre-, intra-, and postoperative risk factor influencing the anastomosis outcome. The presence of a long gap between the two esophageal ends, with consequent anastomotic tension, is determinant for stricture formation and its response to treatment. The cornerstone of treatment is endoscopic dilation, whose primary aims are to achieve symptom relief, allow age-appropriate capacity for oral feeding, and reduce the risk of pulmonary aspiration. No clear advantage of either balloon or bougie dilator has been demonstrated; therefore, the choice is based on operator experience and comfort with the equipment. Retrospective evidences suggest that selective dilatations (performed only in symptomatic patients results in significantly less number of dilatation sessions than routine dilations (performed to prevent symptoms with equal long

2017-01-01

Objectives: Benign paroxysmal positional vertigo is a common vestibular disorder and it may be idiopathic or secondary to some conditions such as surgery, but rare following laparoscopic surgery. Methods: We report two cases of benign paroxysmal positional vertigo secondary to laparoscopic surgery, one after laparoscopic cholecystectomy in a 51-year-old man and another following laparoscopic hysterectomy in a 60-year-old woman. Results: Both patients were treated successfully with manual or device-assisted canalith repositioning maneuvers, with no recurrence on the follow-up of 6 -18 months. Conclusions: Benign paroxysmal positional vertigo is a rare but possible complication of laparoscopic surgery. Both manual and device-assisted repositioning maneuvers are effective treatments for this condition, with good efficacy and prognosis. PMID:28255446

Does Dysphagia Indicate Recurrence of Benign Esophageal Strictures?

Directory of Open Access Journals (Sweden)

Olle Ekberg

1995-01-01

Full Text Available Esophageal dilatation in dysphagic patients with benign strictures is usually considered successful if the patients' dysphagia is alleviated. However, the relation between dysphagia and the diameter of a stricture is not well understood. Moreover, the dysphagia may also be caused by an underlying esophageal motor disorder. In order to compare symptoms and objective measurements of esophageal stricture, 28 patients were studied with interview and a radiologic esophagram. The latter included swallowing of a solid bolus. All patients underwent successful balloon dilatation at least one month prior to this study. Recurrence of a stricture with a diameter of less than 13 mm was diagnosed by the barium swallow in 21 patients. Recurrence of dysphagia was seen in 15 patients. Thirteen patients denied any swallowing symptoms. Chest pain was present in 9 patients. Of 15 patients with dysphagia 2 (13% had no narrowing but severe esophageal dysmotility. Of 13 patients without dysphagia 9 (69% had a stricture with a diameter of 13 mm or less. Of 21 patients with a stricture of 13 mm or less 14 (67% were symptomatic while 7 (33% were asymptomatic. Four of 11 patients with retrosternal pain had a stricture of less than 10 mm. Three patients with retrosternal pain and obstruction had severe esophageal dysmotility. Whether or not the patients have dysphagia may be more related to diet and eating habits than to the true diameter of their esophageal narrowing. We conclude that the clinical history is non-reliable for evaluating the results of esophageal stricture dilatation. In order to get an objective measurement of therapeutic outcome, barium swallow including a solid bolus is recommended.

A neural network to predict symptomatic lung injury

International Nuclear Information System (INIS)

Munley, M.T.; Lo, J.Y.

1999-01-01

A nonlinear neural network that simultaneously uses pre-radiotherapy (RT) biological and physical data was developed to predict symptomatic lung injury. The input data were pre-RT pulmonary function, three-dimensional treatment plan doses and demographics. The output was a single value between 0 (asymptomatic) and 1 (symptomatic) to predict the likelihood that a particular patient would become symptomatic. The network was trained on data from 97 patients for 400 iterations with the goal to minimize the mean-squared error. Statistical analysis was performed on the resulting network to determine the model's accuracy. Results from the neural network were compared with those given by traditional linear discriminate analysis and the dose-volume histogram reduction (DVHR) scheme of Kutcher. Receiver-operator characteristic (ROC) analysis was performed on the resulting network which had Az=0.833±0.04. (Az is the area under the ROC curve.) Linear discriminate multivariate analysis yielded an Az=0.813±0.06. The DVHR method had Az=0.521±0.08. The network was also used to rank the significance of the input variables. Future studies will be conducted to improve network accuracy and to include functional imaging data. (author)

2002-01-01

Full Text Available Symptomatic dystonia can be the result of various metabolic, degenerative diseases, the consumption of certain medications or exposure to toxic agents. However, only symptomatic dystonia with focal structural lesion provides a significant "window" for, at least indirect, perception of aetiopa-thogenesis and pathomorphological substratum of idiopathic dystonia. Our study included 57 patients with symptomatic dystonia, which as a base had focal or multifocal lesions, of whom 7 patients had generalized dystonia, 18 hemidystonia, 6 segmental dystonia, 7 torticollis, 6 blepharospasm, 7 hand dystonia, 3 spasmodic dysphonia, and 3 had oromandibular dystonia. Stroke was highly statistically the most frequent cause of structural lesions (33/57 or 58%. Relevant pathomorphological changes were present in 50/57 (88% patients, of whom 25 (50% had lesion in the lenticular nucleus (including individual damage of the putamen and globus pallidus, 12/50 (24% had damage of the thalamus and 6/50 (12% had damage of the brainstem. Generalized dystonia was most frequently associated with bilateral lesion of the putamen, hemidystonia with lesion of contralateral putamen, torticollis with damage of the caudate nucleus, hand dystonia with lesion of the thalamus and blepharospasm with lesion of the upper brainstem.

Selin Tural Emon

2017-01-01

Full Text Available Xanthogranulomas (XGRs of the choroid plexus are rare, asymptomatic, and benign lesions usually found incidentally. Here, we present a case of a 47-year-old male with bilateral XGR of the choroid plexus with periventricular edema and discuss our case in relation to a review of existing literature pertaining to the radiology of XGRs. To the best of our knowledge, this is the first reported case of bilateral trigonal XGR causing brain edema without ventricular dilatation. Despite the fact that they can cause hydrocephalus, XGRs are silent and benign lesions. Although the etiopathology of XGRs remains poorly understood, enhanced imaging analyses may provide additional information regarding edema and focal white matter signal changes.

Wobrock, T; Köhler, J; Klein, P; Falkai, P

2009-08-01

Symptomatic remission was defined as a score of mild or less on each of eight key schizophrenia symptoms on the Positive and Negative Syndrome Scale (PANSS-8). To evaluate the symptomatic remission criterion in clinical practice and to determine predictors for achieving symptomatic remission, a 12-week non-interventional study (NIS) with quetiapine was conducted in Germany. For the comparison of patients with and without symptomatic remission, sociodemographic and clinical variables of 693 patients were analyzed by logistic regression for their predictive value to achieve remission. Four hundred and four patients (58.3%) achieved symptomatic remission after 12 weeks' treatment with quetiapine. Remission was significantly predicted by a low degree of PANSS-8 total score, PANSS single items blunted affect (N1), social withdrawal (N4), lack of spontaneity (N6), mannerism and posturing (G5), and low disease severity (CGI-S) at baseline. Predictors of non-remission were older age, diagnosis of schizophrenic residuum, multiple previous episodes, longer duration of current episode, presence of concomitant diseases, and alcohol abuse. This study demonstrated that the majority of schizophrenia out-patients achieved symptomatic remission after 12 weeks treatment and confirms the importance of managing negative symptoms in order to achieve disease remission.

The concept of symptomatic epilepsy and the complexities of assigning cause in epilepsy.

Science.gov (United States)

Shorvon, Simon

2014-03-01

The concept of symptomatic epilepsy and the difficulties in assigning cause in epilepsy are described. A historical review is given, emphasizing aspects of the history which are relevant today. The historical review is divided into three approximately semicentenial periods (1860-1910, 1910-1960, 1960-present). A definition of symptomatic epilepsy and this is followed by listing of causes of symptomatic epilepsy. The fact that not all the causes of idiopathic epilepsy are genetic is discussed. A category of provoked epilepsy is proposed. The complexities in assigning cause include the following: the multifactorial nature of epilepsy, the distinction between remote and proximate causes, the role of nongenetic factors in idiopathic epilepsy, the role of investigation in determining the range of causes, the fact that not all symptomatic epilepsy is acquired, the nosological position of provoked epilepsy and the view of epilepsy as a process, and the differentiation of new-onset and established epilepsy. The newly proposed ILAE classification of epilepsy and its changes in terminologies and the difficulties in the concept of acute symptomatic epilepsy are discussed, including the inconsistencies and gray areas and the distinction between idiopathic, symptomatic, and provoked epilepsies. Points to be considered in future work are listed. Copyright © 2013 Elsevier Inc. All rights reserved.

Temporal dynamics of host molecular responses differentiate symptomatic and asymptomatic influenza a infection.

Yongsheng Huang

2011-08-01

Full Text Available Exposure to influenza viruses is necessary, but not sufficient, for healthy human hosts to develop symptomatic illness. The host response is an important determinant of disease progression. In order to delineate host molecular responses that differentiate symptomatic and asymptomatic Influenza A infection, we inoculated 17 healthy adults with live influenza (H3N2/Wisconsin and examined changes in host peripheral blood gene expression at 16 timepoints over 132 hours. Here we present distinct transcriptional dynamics of host responses unique to asymptomatic and symptomatic infections. We show that symptomatic hosts invoke, simultaneously, multiple pattern recognition receptors-mediated antiviral and inflammatory responses that may relate to virus-induced oxidative stress. In contrast, asymptomatic subjects tightly regulate these responses and exhibit elevated expression of genes that function in antioxidant responses and cell-mediated responses. We reveal an ab initio molecular signature that strongly correlates to symptomatic clinical disease and biomarkers whose expression patterns best discriminate early from late phases of infection. Our results establish a temporal pattern of host molecular responses that differentiates symptomatic from asymptomatic infections and reveals an asymptomatic host-unique non-passive response signature, suggesting novel putative molecular targets for both prognostic assessment and ameliorative therapeutic intervention in seasonal and pandemic influenza.

publication when searching the electronic databases. Randomised controlled trials of systemic antibiotics in adults with a clinical diagnosis of symptomatic apical periodontitis or acute apical abscess, with or without surgical intervention (considered in this situation to be extraction, incision and drainage or endodontic treatment) and with or without analgesics. Two review authors screened the results of the searches against inclusion criteria, extracted data and assessed risk of bias independently and in duplicate. We calculated mean differences (MD) (standardised mean difference (SMD) when different scales were reported) and 95% confidence intervals (CI) for continuous data and, where results were meta-analysed, we used a fixed-effect model as there were fewer than four studies. We contacted study authors to obtain missing information. We included two trials in this review, with 62 participants included in the analyses. Both trials were conducted in university dental schools in the USA and compared the effects of oral penicillin V potassium (penicillin VK) versus a matched placebo given in conjunction with a surgical intervention (total or partial pulpectomy) and analgesics to adults with acute apical abscess or symptomatic necrotic tooth (no signs of spreading infection or systemic involvement (fever, malaise)). We assessed one study as having a high risk of bias and the other study as having unclear risk of bias.The primary outcome variables presented were participant-reported pain and swelling (one trial also reported participant-reported percussion pain). One study reported the type and number of analgesics taken by participants. One study recorded the incidence of postoperative endodontic flare-ups (people who returned with symptoms that necessitated further treatment). Adverse effects as reported in one study were diarrhoea (one participant, placebo group) and fatigue and reduced energy postoperatively (one participant, antibiotic group). No studies reporting

The concept of symptomatic and functional remission represents an important challenge in the care of the mentally ill, particularly in patients with schizophrenia. Operational criteria for symptomatic remission in schizophrenia have been proposed by Andreasen et al. (2005). Over the last decade, these criteria have been widely validated; however few studies have been conducted outside developed countries. Moreover, the association of symptomatic remission with functional outcome has not yet been established in developing countries including Tunisia, as there may be variability in the social and familial environment. To determine the frequency and associated factors of symptomatic remission in a sample of Tunisian out-patients with schizophrenia and to explore the relationship between symptomatic remission and some indicators of social functioning. A cross-sectional study was carried-out on 115 out-patients with schizophrenia (87 males, 28 females, mean age=37.56±10.2 years) in the psychiatry department of the university hospital in Monastir (Tunisia). Nearly all of the patients (98.26%) had been hospitalized at least once in a psychiatric unit. The last hospitalization dated back to 39 months on average (range=6 months to 16 years). Symptomatic remission was assessed by the eight core items of the positive and negative syndrome scale (PANSS). These are the items P1 "Delusions"; P3 "Hallucinatory behavior" and G9 "Unusual thought content" for the positive dimension, the items P2 "Conceptual disorganization" and G5 "Mannerism and disorders of posture" for the disorganization dimension and the items N1 "Blunted affect", N4 "Social withdrawal" and N6 "Lack of spontaneity and flow of conversation" for the negative dimension. A score of mild or less on all eight-core symptoms constitutes symptomatic remission. This symptom level should have been maintained for six months. The social functioning was assessed by the Social and Occupational Functioning Assessment Scale

To investigate the impact of different definitions on the frequency of benign multiple sclerosis (MS) in patients with a long follow-up, and to study the presence of non-motor symptoms and employment across the definitions. All patients alive (n = 188) with disease onset during 1976-1986 in Hordaland County, Norway, were clinically examined including the Expanded Disability Status Scale (EDSS) in 2003. Non-motor symptoms which included depression, cognitive impairment, fatigue and pain, and employment status were also registered. Three definitions of benign MS were used based on the following EDSS cut-off values: 2.0, 3.0 and 4.0. Two additional definitions were added using an EDSS part-time employment status. The frequency of benign MS increased from 14.5% for EDSS benign MS.

We analyzed clinical factors related to uptake on a Tc-99 m HDP bone scan of the accessory navicular (AN). We retrospectively reviewed patients who had been examined by an orthopedic surgeon and underwent bone scan due to suspected symptomatic AN. A three-point grading system was used to evaluate uptake on bone scan. Relationships between grade, symptoms, age, gender, symptom duration, and bone size were analyzed. In total, 73 ANs (30 asymptomatic, 43 symptomatic) were enrolled. The majority of asymptomatic ANs had no uptake but some had grade 1 (n = 8) or 2 (n = 2) uptake. All asymptomatic ANs with uptake remained asymptomatic during follow-up. For the asymptomatic ANs, larger bones showed a higher grade. With a cut-off value of size ≤6.8 mm, there is no chance of uptake. All symptomatic ANs showed uptake on bone scan. For symptomatic ANs, larger size and shorter pain duration were related to a higher grade. Age, gender, and left-/right-sideness were not related to grade. Multiple regressions revealed that only uptake grade, not size or symptom duration, was the significant risk factor for a symptomatic AN. With a cut-off value of grade <1, a symptomatic AN could be ruled out with a negative predictive value of 100 %. Bone scanning is useful for symptomatic ANs with a high negative predictive value. Higher grade is related to larger size and shorter pain duration. For asymptomatic ANs, grade was related to size but did not predict symptom development

Benign prostatic hyperplasia (BPH) is a common and progressive disease affecting elderly males, often associated with lower urinary tract symptoms (LUTS). α1-blockers are the mainstay in symptomatic therapy of BPH. Because of their greater uroselectivity and minimal hemodynamic effects, alfuzosin, tamsulosin, and silodosin are generally preferred. The aim of this study was to compare the efficacy and tolerability of alfuzosin, tamsulosin, and silodosin in patients with BPH and LUTS. Ninety subjects with BPH and LUTS were randomized into three groups of thirty in each, to receive alfuzosin sustained release (SR) 10 mg, tamsulosin 0.4 mg, or silodosin 8 mg for 12 weeks. The primary outcome measure was a change in the International Prostate Symptom Score (IPSS), and the secondary outcome measures were changes in individual subjective symptom scores, quality of life score (QLS), and peak flow rate (Qmax) from baseline. The treatment response was monitored at 2, 4, 8, and 12 weeks. IPSS improved by 88.18%, 72.12%, and 82.23% in alfuzosin SR, tamsulosin and silodosin groups (P 75% in all the three groups (P tamsulosin (P = 0.025 and P tamsulosin (three subjects). Alfuzosin, tamsulosin, and silodosin showed similar efficacy in improvement of LUTS secondary to BPH, with good tolerability, acceptability, and minimum hemodynamic adverse effects. Alfuzosin, tamsulosin, and silodosin are comparable in efficacy in symptomatic management of BPH. The occurrence of QTc prolongation in three subjects with tamsulosin in the present study is an unexpected adverse event as there are no reports of QTc prolongation with tamsulosin in any of the previous studies.

We assessed the usefulness of resistive index(RI) on spectral analysis of doppler sonography for differential diagnosis of benign and malignant breast lesions. We retrospectively reviewed 29 benign and 22 malignant lesions of breast, which were examined preoperatively with color and duplex Doppler and were confirmed by histopathologically after operation. We analyzed the average and distribution of RI in benign and malignant lesions. Although, there was no difference in the average values of RI in benign and malignant breast lesions, the distribution of RI was below 0.7 in eighteen cases (62%) of benign lesions, and above 0.7 in eighteen cases (82%) of malignant lesions. Thus, RI is valuable for differentiation between benign and malignant lesions of breast. Measurement of RI in breast disease using color and duplex Doppler study is useful modality adjunct to the conventional ultrasonographic differentiation of benign and malignant lesions

We quantitatively evaluated the effects of landscape factors on the distribution of symptomatic raccoon dogs with sarcoptic mange along an urban gradient. We used 246 camera traps (182 traps from April 2005 to December 2006; 64 traps from September 2009 to October 2010) to record the occurrence of asymptomatic and symptomatic raccoon dogs at 21 survey sites along an urban-rural gradient in the Tama Hills area of Tokyo. Each occurrence was explained in terms of the surrounding forest, agricultural, and grassland areas and additional factors (i.e., seasonal variations and survey methods) at various spatial scales using a generalized additive mixed model (GAMM). In our analysis, a 1000-m radius was identified as the important spatial scale for asymptomatic and symptomatic raccoon dog occurrence. The peak of the predicted occurrence probability of asymptomatic raccoon dogs appeared in the intermediate forest landscape as opposed to non-forest and forest landscapes. However, a high occurrence probability of symptomatic raccoon dogs was detected in non-forest and intermediate forest landscapes (i.e., urban and suburban) as opposed to a forest landscape, presumably because of animals occurring at much higher densities in more urbanized areas. Therefore, our results suggest that human-modified landscapes play an important role in the high occurrence of sarcoptic mange in raccoon dogs.

Despite the upsurge of research regarding cognitive impairment in schizophrenia we still lack adequate understanding of the executive functioning of patients in symptomatic remission. Moreover, the cognitive functioning of patients in partial remission has not been studied previously although they comprise a significant proportion of schizophrenia patients. The current study therefore examined the executive functioning of patients in full symptomatic remission and for the first time assessed two sub-groups of patients in partial remission. Executive functioning of five groups was compared; symptomatic patients, patients in positive symptomatic remission, negative symptomatic remission, full symptomatic remission (SP, PSR, NSR, and FSR; N=101) and healthy controls (N=37). A graded cognitive profile was evident between the groups. SP patients exhibited widespread executive dysfunction while the performance of FSR patients was comparable to that of the healthy controls. Both PSR and NSR patients had working memory deficits, with PSR patients showing additional deficits in cognitive planning. The findings are encouraging, tentatively suggesting intact executive functioning among patients in full symptomatic remission. The graded cognitive profile of the patient groups strengthens earlier findings indicating the significant role of negative symptoms in determining executive dysfunction in schizophrenia. The findings point toward potential targets for therapeutic efforts and emphasize the need for further research of sub-groups of schizophrenia patients in partial remission.

Symptomatic Congenital Cytomegalovirus Infection in Children of Seropositive Women

Directory of Open Access Journals (Sweden)

Ines Mack

2017-06-01

Full Text Available Cytomegalovirus (CMV is the most frequent congenital virus infection worldwide. The risk of congenital CMV (cCMV transmission is highest in seronegative women who acquire primary CMV infection during pregnancy. A growing body of evidence indicates that secondary CMV infections in pregnant women with preconceptual immunity (either through reactivation of latent virus or re-infection with a new strain of CMV contribute to a much greater proportion of symptomatic cCMV than was previously thought. Here, we describe a case of symptomatic cCMV infection in the newborn of a woman with proven immunity prior to pregnancy. Diagnosis was confirmed by CMV PCR from amniotic fluid and fetal MR imaging. The newborn presented with typical cCMV symptoms including jaundice, hepatosplenomegaly, cholestasis, petechiae, small head circumference, and sensorineural hearing loss, the most common neurologic sequela. CMV was detected in infant blood and urine by PCR, and intravenous ganciclovir was initiated and continued orally for 6 weeks totally. Apart from persisting right-sided deafness, the child exhibited normal neurological development up through the last follow-up at 4.5 years. To date, the most effective strategy to prevent vertical CMV transmission is hygiene counseling for women of childbearing age, which, in our case, and in concordance with recent literature, applies to seronegative, as well as seropositive, women. Once an expecting mother shows seroconversion or signs of an active CMV infection, there are no established procedures to reduce the risk of transmission, or therapeutic options for the fetus with signs of infection. After birth, symptomatic infants can be treated with ganciclovir to inhibit viral replication and improve hearing ability and neurodevelopmental outcome. A comprehensive review of the literature, including our case study, reveals the most current and significant diagnostic and treatment options available. In conclusion, the triad

The outcome evaluation for the revascularization of intracranial vascular stenoses has not been fully described due to the highly technical nature of the procedure. We report here on the early and late clinical outcome of angioplasty and/or stenting of symptomatic severe intracranial vascular stenoses at a single institute. Since 1995, we have treated 35 patients with symptomatic intracranial vascular stenosis (more than 70% stenosis, mean stenosis: 78.6% {+-} 6.2%). Angioplasty (n = 19) was performed for the horizontal segment of the middle cerebral artery (M1) (n = 16) and the basilar artery (BA) (n = 1), the intradural vertebral artery (VA) (n = 1), and the cavernous internal carotid artery (ICA) (n = 1). Stenting (n = 16) was performed for the cavernous or petrous ICAs (n = 9), the intradural VA (n = 3), BA (n = 2), and M1 (n = 2) artery. We assessed the angiographic success (defined as residual stenosis < 50%) rate, the periprocedural complications during the 30-day periprocedural period, the symptomatic recurrence and restenosis during a mean 22-month follow-up (FU) period. The Kaplan-Meier estimate of the cumulative even-free rate of the major cerebrovascular events, i.e. death, stroke or restenosis, was also done. Angiographic success was achieved in 97% of our patients (34/35). There were four procedure-related complications (11%) including a death and a minor stroke. During the mean 22-month FU, the asymptomatic restenosis rate was 9% and the symptomatic restenosis rate was 6% in the target lesion and 9% in all the vascular territories. The Kaplan-Meier estimate was 70.6% (95% confidence interval = 46.5-94.7) after 33 month of FU. In addition to a high angiographic success rate and an acceptable periprocedural complication rate, intracranial angioplasty and/or stenting revealed a relatively low symptomatic recurrence rate. Hemorrhage is a rare, but the physician must aware that potentially fatal periprocedural complications can occur.

Full Text Available BACKGROUND Benign Breast diseases are of unknown aetiology, they could be inflammatory or non-inflammatory disorders of breast disease. Among these, NIBBD is a most confusing surgical disorder, diagnosis should be made at least after three assessments. AIM  To evaluate the prevalence of NIBBD.  Clinical analysis of NIBBD in women and reproductive age group between 20-40 years.  To prevent radical breast surgery in NIBBD.  To know about benign breast lesions in males excluding gynaecomastia. MATERIALS AND METHODS A clinicopathological study of NIBBD was taken in KIMS Hospital, Hubli, a tertiary care government hospital between June 2014 to June 2015. A total of 56 cases were selected of which 51 cases were submitted for clinicopathological study. RESULTS Increase incidents of fibroadenoma in females, in young age group, is noticed due to early menarche, early marriage, multiparity, fibrocystic diseases involvement at the age of 35 years, usually appear on either side of the breast. Moderate loss of glandular tissue is accelerated and replaced by connective tissue, hence fibrocystic diseases appear at late age group. Gynaecomastia is the only NIBBD, seen unilaterally in males. CONCLUSION NIBBD is more common in childbearing age group i.e. 15 to 45 years of age. Triple assessment is the choice of diagnosis, imaging modality being USG of the breast and mammography in suspected cases of malignancy. Most of the patients require surgical intervention and remodelling of the Breast, according to the volume loss of breast tissue.

Benign prostatic hyperplasia (BPH), a senile disorder affects male of and above 40 years characterized by retention, incomplete voiding, dribbling, hesitancy, and incontinence of urine. This condition is comparable with Mootraghata in Ayurveda. Surgical intervention has been accepted as standard management, but has acute cystitis, acute epididymitis, erectile dysfunction, retrograde ejaculation, etc. as complications. Conservative treatment with modern medicine is also associated with side effects. Hence, to avoid such complications and improve the quality of life in senile age, conservative management with Ayurveda is attempted. To evaluate clinical efficacy of Kanchanara Guggulu and Dhanyaka Gokshura Ghrita Matra Basti in Mootraghata. Total 30 patients having signs and symptoms of BPH were selected from OPD and IPD of Shalya Tantra and enrolled equally into three groups (n = 10). Patients of Group A were administered with Kanchanara Guggulu (500 mg, 3 times a day orally), Group B were with Dhanyaka Gokshura Ghrita Matra Basti, while patients of Group C were administered both the drugs for 21 days. International prostate symptom score (IPSS) was used to assess the efficacy. paired and unpaired "t" test, Chi-square test were applied for significance. In IPSS, Group B had shown the better results (84.27%) than the Group A (72.68%) and Group C (82.10%). In all objective parameters, Group C had shown better effect (23.60%) than Group A (15.70%) and Group B (18.24%). Symptomatic relief was better in Group B than Groups A and C. Comparison between three groups on objective parameters was better in Group C than in Group A and B. Kanchanara Guggulu orally and Dhanyaka Gokshura Ghrita Matra Basti is effective conservative management for symptomatic relief in BPH of senile age.

The ability of alliance to predict outcome has been widely demonstrated, but less is known about the effect of the level of congruence between patient and therapist alliance ratings on outcome. In the current study we examined whether the degree of congruence between patient and therapist alliance ratings can predict symptomatic levels 1 month later in treatment. The sample consisted of 127 patient-therapist dyads. Patients and therapists reported on their alliance levels, and patients reported their symptomatic levels 1 month later. Polynomial regression and response surface analysis were used to examine congruence. Findings suggest that when the congruence level of patient and therapist alliance ratings was not taken into account, only the therapist's alliance served as a significant predictor of symptomatic levels. But when the degree of congruence between patient and therapist alliance ratings was considered, the degree of congruence was a significant predictor of symptomatic levels 1 month later in treatment. Findings support the importance of the level of congruence between patient and therapist alliance ratings in predicting patient's symptomatic levels.

Spread and Control of Mobile Benign Worm Based on Two-Stage Repairing Mechanism

Directory of Open Access Journals (Sweden)

Meng Wang

2014-01-01

Full Text Available Both in traditional social network and in mobile network environment, the worm is a serious threat, and this threat is growing all the time. Mobile smartphones generally promote the development of mobile network. The traditional antivirus technologies have become powerless when facing mobile networks. The development of benign worms, especially active benign worms and passive benign worms, has become a new network security measure. In this paper, we focused on the spread of worm in mobile environment and proposed the benign worm control and repair mechanism. The control process of mobile benign worms is divided into two stages: the first stage is rapid repair control, which uses active benign worm to deal with malicious worm in the mobile network; when the network is relatively stable, it enters the second stage of postrepair and uses passive mode to optimize the environment for the purpose of controlling the mobile network. Considering whether the existence of benign worm, we simplified the model and analyzed the four situations. Finally, we use simulation to verify the model. This control mechanism for benign worm propagation is of guiding significance to control the network security.

The aim of this study is to assess the levels and diagnostic accuracy of a set of bone resorption biomarkers, including TRAP-5, RANKL, and OPG in symptomatic and asymptomatic apical lesions and controls. Apical tissues from symptomatic and asymptomatic apical periodontitis patients and periodontal ligaments from healthy teeth extracted for orthodontic reasons were processed for tissue homogenization and the levels of TRAP-5, RANKL, and OPG were determined by multiplex assay. Marker levels were analyzed by Kruskal Wallis test, and diagnostic accuracy was analyzed with ROC curves. Higher levels of RANKL, OPG, and RANKL/OPG ratio were determined in both types of apical lesions compared to healthy periodontal ligament, whereas higher TRAP-5 levels were found only in symptomatic apical lesions (p apical lesions versus healthy controls (AUC = 0.69, p asymptomatic apical periodontitis (AUC = 0.71, p Apical lesions showed higher RANKL and OPG levels than healthy tissues. TRAP-5 levels were the highest in symptomatic apical lesions, suggesting that these represent a progressive state, and showed diagnostic potential. Clinically symptomatic apical periodontitis might represent biologically progressive apical lesions based on TRAP5 levels. TRAP5 has diagnostic potential to identify these lesions, representing a candidate prognostic biomarker.

To clarify the characteristic sonographic features of benign soft tissue tumors and to evaluate the usefulness of sonographic imaging. We retrospectively reviewed ultrasonographic images of 70 cases in 68 patients with histologically proved benign soft tissue tumors. The tumors include 33 lipomas, 11 hemangiomas, 11 lymphangiomas, 7 neurilemmomas, 4 epidermoid cysts, 2 fibromas, 1 mesenchymoma, and 1 myxoma. The sonographic appearances of the lesions were mainly solid in 53 cases(33 lipomas, 8 hemangiomas, 2 lymphangiomas, 7 neurilemmomas, 2 fibromas and 1 mesenchymoma), mainly cystic in 14 cases(1 hemangioma, 8 lymphangiomas, 4 epidermoid cysts, and 1 myxomal), and mixed in 3 cases(2 hemangiomas and 1 lymphangioma). Although an accurate histologic prediction could not be made in most cases, certain patterns appeared to be characteristic of specific tumor types. 26 cases(78%) of lipoma were seen as lentiform, iso- or hyperechoic, solid mass. Hemangioma had variable appearance and characteristic calcifications were seen in 3 cases. Unicameral or multiseptated cystic mass with variable thickness of echogenic septa and solid portion was the characteristic finding of lymhangioma. Neurilemmoma showed lobulated, oval to round , relatively hypoechoic mass or with without internal cystic portion. Sonographic evaluation of benign soft tissue tumors is useful in demonstrating the location, size, extent, and internal characteristic of the mass. A relatively confident diagnosis can made when the characteristic features of the benign soft tissue tumor are present on sonographic imaging

Transurethral microwave thermotherapy (TUMT) is being used with increasing frequency by urologists as a minimally invasive therapy for benign prostatic hyperplasia (BPH). There are various modifications to this technology, with each manufacturer touting safety and efficacy. We review the rationale of TUMT, as well as the historical safety and efficacy of this approach. We reviewed the medical literature, including peer reviewed articles and abstracts. In addition, we analyzed promotional material distributed by various manufacturers with respect to scientific accuracy. TUMT results in consistent improvement in symptoms and peak urinary flow rate. Symptom improvement ranges between 9 and 11 points, compared to a 6-point improvement in sham treated patients, and peak urinary flow rate increases 3 to 5 ml per second. The degree of coagulation necrosis is different among the various TUMT devices. Although coagulation necrosis is believed to be an important proxy for clinical success, there are few data that correlate this factor with the magnitude of either symptomatic or uroflow improvement. TUMT is a safe and effective therapy for the treatment of lower urinary tract symptoms secondary to BPH. In addition, there are distinct advantages to each of the devices. However, intense marketing and hyperbole have dominated this segment of the BPH market. Ultimately, the most effective TUMT device can only be determined by direct comparison studies.

Full Text Available AIMS AND OBJECTIVES: The presence of a lump in the breast is a great cause of anxiety and apprehension, to the female patients. This may be accrued to the increasing public awareness of breast cancer which is presently the most common female malignancy worldwide. The aim of th is study was to determine the frequency of benign breast diseases (BBD amongst patients in tertiary care institute of central India. MATERIAL AND METHOD: It was a cohort study. In this study all patients visiting the surgical OPD clinic with breast proble ms were included. This study was conducted at Chirayu Medical College and Hospital Bhopal over a period of four years starting from November 2010 to November 2014. All patients with definite symptoms and sign of malignancy or those who on evaluation were d iagnosed as carcinoma of breast were excluded from this study. RESULTS: A total of 112 patients were included in the study. About 54.4% (61/112 patients belonged to 3rd decade of life followed by 21.4% (24/112 from 4th decade (age between: 31 – 40 years . The most common benign breast disease, seen in 33.9% (38/112 of patients was fibro adenoma followed by fibrocystic disease seen in about 19.6% (22/112 patients. Breast abscess was seen in 20/112(17.8% and Mastalgia was present in 15/112 (13.3% patien ts. CONCLUSION: In females of reproductive age group Benign Breast Diseases (BBD are common problems. Fibro adenoma is the commonest of all benign breast disease mostly seen in 2nd and 3rd decade of life. Fibrocystic disease of the breast is the next comm on BBD whose incidence increases with increasing age. Routine mammographic screening of high risk groups aimed at early detection of these premalignant lesions is therefore indicated. A biopsy with histological diagnosis of all breast lumps is also recomme nded as this will aid in the detection of premalignant lesions particularly in low resource settings

Objective: To analyse the characteristics of orbital benign and malignant masses on diffusion weighted imaging in combination with conventional MR imaging and evaluate the diagnostic value of apparent diffusion coefficient in distinguishing benign and malignant orbital lesions. Methods: Seventy- seven cases with orbital masses, including fifty-five benign lesions and twenty-two malignant tumors, who underwent conventional MRI and diffusion imaging scanning were studied with use of a 1.5 T magnetic resonance system. Quantitative ADC measurements of masses (ADCM) and of the white matter of contralateral temporal lobe (ADC w ) were made with two different b-values of 0 and 1000 s/mm 2 . The ADC ratio (ADCR) of the lesion to the control was calculated. The receiver operating characteristic curves(ROC) were constructed using various cut points of ADCM and ADCR for different parameters to differentiate between benign and malignant masses. The area under the ROC curve for each parameter was also calculated. Results: All cases were proved by histopathology. The mean ADCM and ADCR of benign orbital masses were (1.56 ± 0.75) x 10 -3 mm 2 /s and 1.85 ± 0.91, respectively. The mean ADCM and ADCR of malignant orbital masses were (1.09 ± 0.42) x 10 -3 mm 2 /s and 1.28 ± 0.53, respectively. There were significant difference both between ADCM and ADCR of benign and malignant masses (t=2.803, 2.735, P -3 mm 2 /s for ADC M of the tumor, the sensitivity, specificity and accuracy were 59.1%, 78.2% and 72.7%, respectively. And by using cut point of 1.24 for ADCR, the sensitivity, specificity and accuracy were 59.1%, 76.4%, 71.4%, respectively. Conclusion: Diffusion MR imaging and ADC value could provide additional information for conventional magnetic resonance imaging in distinguishing benign and malignant orbital masses. (authors)

Objective: To differentiate MR imaging characteristics of symptomatic as compared with asymptomatic Achilles tendons.Design: 1.5 T MR images of 94 feet (88 patients) with ''abnormal'' MR examinations were retrospectively evaluated and clinically correlated. Two masked, independent observers systematically evaluated for intratendon T2 signal, tendon thickness, presence of peritendonitis, retrocalcaneal bursal fluid volume, pre-Achilles edema, bone marrow edema at the Achilles insertion, and tears (interstitial, partial, complete). These findings were correlated with symptoms (onset and duration) and physical examination results (tenderness, palpable defects, increased angle of resting dorsiflexion).Results: Of the 94 ankles, 64 ankles (32 females, 29 males) were clinically symptomatic. No relationship between Achilles tendon disorders and age or gender was identified. Asymptomatic Achilles tendons frequently demonstrated mild increased intratendon signal (21/30), 0.747 cm average tendon thickness, peritendonitis (11/30), pre-Achilles edema (12/30), and 0.104 ml average retrocalcaneal bursal fluid volume. Symptomatic patients had thicker tendons (0.877 cm), greater retrocalcaneal fluid volume (0.278 ml), more frequent tears (23/64), a similar frequency of peritendonitis (22/64) but less frequent pre-Achilles edema (18/64). Sixty-four percent of the Achilles tendon tears were interstitial. Except for two interstitial tears in control patients, the majority of Achilles tears were in symptomatic patients (14/16). Only symptomatic tendons demonstrated partial or complete tendon tears. In addition, calcaneal edema was found almost exclusively in actively symptomatic patients. Thicker tendons were associated more often with chronic symptoms and with tears. When present in symptomatic patients, peritendonitis was usually associated with acute symptoms. The presence of pre-Achilles edema, however, did not distinguish acute from chronic disorders.Conclusion: There is

Chronic atrophic gastritis (CAG) is an important precursor lesion of intestinal gastric cancer. As it is typically asymptomatic, epidemiological data on the incidence of CAG are sparse. We aimed to provide an overview of published data on CAG incidence (overall and according to risk factors) from follow-up studies. Articles with information on incidence of CAG published in English until 26th of July 2009 were identified through a systematic MEDLINE and EMBASE search. Data extracted include study characteristics and key findings regarding the incidence of CAG. A meta-analysis was performed on the association between Helicobacter pylori infection and CAG incidence. Overall, data on CAG incidence were available from 14 studies, in 7 studies incidence could be estimated according to H. pylori infection. Most studies were conducted in symptomatic or high risk populations and the maximum number of incident cases was 284. Incidence estimates ranged from 0 to 11% per year and were consistently below 1% in patients not infected with H. pylori. The highest incidence was observed in a special study conducted on ulcer patients treated by proximal gastric vagotomy. Rate ratios for the association between H. pylori infection and CAG incidence ranged from 2.4 to 7.6 with a summary estimate of 5.0 (95% confidence interval: 3.1-8.3). Incidence of CAG is very low in the absence of H. pylori infection. There is a need for more population-based studies to provide comparable estimates of incidence and the impact of risk factors in the development of CAG.

The incidence of type 2 diabetes mellitus (T2DM) is increasing in adolescents in most western countries. The time-course of glycemic control and impact of early treatment remain poorly understood. To determine the change in incidence of T2DM, and the time-course of glycemic control in a regional pediatric cohort with T2DM. Retrospective analysis of prospectively collected data on 52 patients with T2DM from a population-based treatment referral cohort from 1 January 1995 to 31 December 2007. The annual incidence of new cases of T2DM in children Auckland region of New Zealand from 1995 [0.5/100,000; 95% confidence interval (CI) 0.0–2.2] to 2007 (2.5/100,000; 95% CI 1.0–5.5). The average annual incidence per 100,000 over the entire period was 1.3 (95% CI 1.0–1.8) overall, 0.1 (0.0–0.4) in Europeans, and 3.4 in both Maori (2.0–5.3) and Pacifica (2.2–5.0). Fifty-seven percent of children were symptomatic at presentation. Fifty-eight percent of patients were treated with insulin from diagnosis, most of whom were symptomatic (p = 0.003). Follow-up data were available for 48 patients with a mean of 2.4 yr. Although insulin therapy was associated with a greater fall in HbA1c values in the first 12 months of treatment (to a nadir of 7.1 vs. 8.1%, p 9% in both groups. Therapy did not affect body mass index standard deviation score (BMI SDS). The incidence of T2DM in childhood or adolescence increased markedly over a 13-yr period in the Auckland region. Long-

Urinary prostate-specific antigen (uPSA) can be used as additional parameter of benign prostatic hyperplasia (BPH) progression. From January 2001 to December 2011, uPSA was determined in 265 patients with benign prostate. Based on total prostate volume (TPV), the patients with benign prostate were divided in two groups: TPV specificity of 0.83 and sensitivity of 0.67. The level of uPSA reflects prostatic hormonal activity and correlates with TPV, PSA and age. UPSA level ≥ 150 ng/mL can be used as additional predictive parameter of BPH progression.

Benign and malignant thyroid nodules after neck irradiation

Fjaelling, M.T.; Tisell, L.E.; Carlsson, S.; Hansson, G.; Lundberg, L.M.; Oden, A.

1986-01-01

A total of 444 persons were examined for the presence of thyroid nodules on average of 43 years after having been treated with x-rays for cervical tuberculous adenitis. Of this total, 101 subjects had undergone surgery for thyroid nodules: 25 for carcinoma (6%) and 76 for benign nodules (17%). Carcinoma occurred with the same frequency in multinodular and uninodular glands. Because of the uneven age distribution in the current series, it could not be decided whether there was a higher susceptibility of the young thyroid to the induction of thyroid carcinoma or benign nodules. The dosage range for the whole series was 0.40 to 50.90 Gy (40-5090 rad). There was a positive correlation between the absorbed radiation dose and the probability of developing benign and malignant thyroid nodules, even after doses of 20 Gy or more. The risk of developing thyroid carcinoma was equal for men and women, while the female-to-male ratio for benign nodules was 2.9:1, indicating that risk factors associated with females are of less importance in irradiated than in nonirradiated populations. The median latency for carcinoma was 40 years, suggesting that the increased risk of thyroid carcinoma after irradiation remains for the rest of the patient's life

Diagnosis and Treatment of Benign Paroxysmal Positional Vertigo

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

The benign vascular tumors of bone represent a diverse group of tumors that can present with a broad spectrum of clinical signs and symptoms. They can also present a significant diagnostic challenge due to their widely variable radiographic imaging and histologic features. Some of the tumors manifest as clearly benign lesions with tissue-specific diagnostic imaging features, while others have non-specific imaging features that may simulate malignant neoplasm. This article will provide a review of the nomenclature and the characteristic radiographic and pathologic features of the benign vascular lesions of bone. The information will aid in improving our diagnostic accuracy and enhance our understanding of the biologic potential of this diverse group of osseous lesions. (orig.)

Background: The incidence of prostate cancer is much lower in Asian men than in Western men. This study investigated whether prostate cancer is associated with prostatitis, benign prostatic hyperplasia (BPH), and other medical conditions in the low-incidence population. Methods: From the claims data obtained from the universal National Health Insurance of Taiwan, we identified 1184 patients with prostate cancer diagnosed from 1997 to 2008. Controls comprised 4736 men randomly selected from a cancer-free population. Both groups were 50 years of age or above. Medical histories between the two groups were compared. Results: Multivariate logistic regression analysis showed that prostatitis and BPH had stronger association with prostate cancer than the other medical conditions tested. Compared with men without prostatitis and BPH, a higher odds ratio (OR) for prostate cancer was associated with BPH (26.2, 95% confidence interval (CI) 20.8–33.0) than with prostatitis (10.5, 95% CI=3.36–32.7). Men with both conditions had an OR of 49.2 (95% CI=34.7–69.9). Conclusion: Men with prostate cancer have strong association with prostatitis and/or BPH. Prostatitis interacts with BPH, resulting in higher estimated relative risk of prostate cancer in men suffering from both conditions. PMID:23612451

Objective: To evaluate the incidence of postoperative venous thromboembolism (VTE) after thoracic surgery and its characteristic. Methods: This was a single-center, prospective cohort study. Patients undergoing major thoracic surgeries between July 2016 and March 2017 at Department of Thoracic Surgery, Beijing Chaoyang Hospital Affiliated to Capital Medical University were enrolled in this study. Besides the routine examination, all patients were screened for deep venous thrombosis (DVT) by using noninvasive duplex lower-extremity ultrasonography after surgery. CT pulmonary angiography (CTPA) was carried out if patients had one of the following conditions including typical symptoms of PE, high Caprini score (>9 points) or new diagnosed postoperative DVT. Caprini risk assessment model was used to detect high risk patients. No patients received any prophylaxis of VTE before surgery. Further data was analyzed for identifying the incidence of postoperative VTE. The t -test, χ 2 test or Wilcoxon rank-sum test was used to analyze the quantitative data and classification data, respectively. Results: Totally 345 patients who undergoing major thoracic surgery were enrolled in this study including 145 benign diseases and 200 malignant diseases.There were 207 male and 138 female, aging from 15 to 85 years. Surgery procedures included 285 lung surgeries, 27 esophagectomies, 22 mediastinal surgeries and 11 other procedures. The overall incidence of VTE was 13.9% (48 of 345) after major thoracic surgery including 39 patients with newly diagnosed DVT (81.2%), 1 patient with PE (2.1%) and 8 patients with DVT+ PE (16.7%). The median time of VTE detected was 4.5 days postoperative. There were 89.6% (43/48) VTE cases diagnosed in 1 week. The incidence of VTE was 9.0% in patients with benign diseases, while 17.5% in malignant diseases (χ 2 =5.112, P patients with pulmonary diseases was 12.6%, among that, in patients with lung cancer and benign lung diseases was 16.4% and 7.5 % (χ 2

Here, we present the clinical presentation and surgical outcomes of women with symptomatic urethral prolapse presenting to our institution over 20 years, and seek to provide treatment recommendations for management of symptomatic urethral prolapse and caruncle. A retrospective review of medical records from female patients who underwent surgery for symptomatic urethral prolapse from June 1995 to August 2015 was performed. Surgical technique consisted of a four-quadrant excisional approach for repair of urethral prolapse. A total of 26 patients were identified with a mean age of 38.8 years (range 3-81). The most common presentations were vaginal bleeding, hematuria, pain, and dysuria. All patients underwent surgical excision of urethral prolapse via a standard approach. Follow-up data was available in 24 patients. Six patients experienced temporary postoperative bleeding, and one patient required placement of a Foley catheter for tamponade. One patient experienced temporary postoperative urinary retention requiring Foley catheter placement. Three patients had visible recurrence of urethral prolapse, for which one later underwent re-excision. Surgical excision of urethral prolapse is a reasonable treatment option in patients who have tried conservative management without relief, as well as in those who present with severe symptoms. Possible complications following excision include postoperative bleeding and recurrence, and patients must be counseled accordingly. In this work, we propose a treatment algorithm for symptomatic urethral prolapse. © 2017 Wiley Periodicals, Inc.

Objective: To investigate MRI features for differentiating borderline from benign mucinous cystadenoma (MC) of the ovary. Methods: Twenty three patients with 23 benign MCs and 19 patients with 20 borderline mucinous cystadenomas (BMC)proven by surgery and pathology underwent MRI, with 23 benign MCs and 20 BMC. MRI features of tumor were evaluated and compared between two groups including location, shape, size, loculation, signal intensity of the fluid, thickness of septa and wall, and vegetations. The findings were correlated with those of pathology. The loculation, the signal intensity of the intracystic content, the thickness of the septation and the wall, and the vegetations between the benign MCs and the BMCs were compared using the Chi-square test.Results Homogenous low signal on T 1 WI and homogenous high signal on T 2 WI were the main signal patterns of benign MC seen more commonly in benign MC (18/23 and 17/23, respectively) than in BMC (5/20 and 8/20, respectively) (χ 2 =12.1979, 5.0553; P<0.05). The honeycomb loculi, high signal on T 1 WI, low signal on T 2 WI, thickened septa or wall (≥5 mm), and vegetations (≥5 mm) were significantly more common in BMC (10/20, 9/20, 8/20, 10/20 and 14/20, respectively) than in benign MC(4/23, 3/23, 1/23, 1/23 and 1/23, respectively) (χ 2 =5.1804, 5.4300, 8.2163, 11.7113 and 20.2990, P<0.05), with the sensitivity and specificity for characterizing BMC of 50.0% and 82.6%, 45.0% and 87.0%, 40.0% and 95.7%, 50.0% and 95.7%, and 70.0% and 95.7%, respectively. When one of honeycomb loculi with low signal on T 2 WI, thickened septa or wall (≥5 mm), and vegetations (≥5 mm) were found, the sensitivity, specificity and accuracy for characterizing BMC were 90.0%, 91.3% and 90.7% respectively. Conclusion: MRI is accurate for demonstrating morphological features of ovarian MC which well correlated to pathological characteristics, and for differentiating BMC from benign MC, thus helpful for making surgery strategy.

To evaluate useful findings and diagnostic value of TI-201 thyroid scan in differentiating benign from malignant nodules. We studied 77 cold thyroid nodules proven histologically(27 malignant and 50 benign). Early (5-15 min) and delayed images(3-5 hours) were obtained after intravenous injection of thallium 201. In these nodules, we retrospectively analyzed the degree of TI-201 uptake in early and delayed images, histopathologic type, size, and presence or absence of cystic change in the sonograms of 22 malignant nodules. Useful finding for diagnosis of malignant nodules was strong uptake of TI-201 in early and delayed images(specificity: 98%, sensitivity: 63%, positive predictive value: 94.4%). Useful finding for benign nodules was no uptake of TI-201 in delayed image(specificity: 88.9%, sensitivity: 68%, positive predictive value: 91.9%). The accuracy of TI-201 thyroid scan in differentiating benign from malignant nodules was 66.2%. The nodules with strong TI-201 uptake in early image and low TI-201 uptake in delayed image were malignant in 29.4%. Cystic changes were found in 40% of malignant nodules with atypical TI-201 uptake. TI-201 thyroid scan showed high specificity in follicular neoplasm and adenomatous goiter in which differentiation of benignancy and malignancy is difficult with only cytologic examination. We consider that TI-201 thyroid scan is valuable in differentiating benign from malignant nodules and when combined with fine needle aspiration and ultrasound examination, it will enable more accurate differential diagnosis between benign and malignant thyroid nodules

2013-01-01

This study was performed to determine the prevalence of bifid mandibular condyles (BMCs) in asymptomatic and symptomatic temporomandibular joint (TMJ) subjects with no traumatic history, and to assess their impact on clinical and radiographic manifestations of TMJ. A total of 3,046 asymptomatic and 4,378 symptomatic patients were included in the study. Cone-beam computed tomography (CBCT) images were reviewed for bifid condyles. T-tests were used to compare the frequency of BMCs when stratified by symptom, gender, and side. In BMC patients, the clinical features of pain and noise, osseous changes, and parasagittal positioning of the condyles were compared between the normally shaped condyle side and the BMC side using chi-squared tests. Fifteen (0.49%) asymptomatic and 22 (0.50%) symptomatic patients were found to have BMCs. Among the bilateral cases, the number of condyles were 19 (0.31%) and 25 (0.29%), respectively. No statistically significant differences were found between asymptomatic and symptomatic patients, between female and male patients, or between the right and left sides (p>0.05). Compared with the normally shaped condyle side, the BMC side showed no statistically significant differences in the distribution of pain and noise, parasagittal condylar position, or condylar osseous changes, with the exception of osteophytes. In the symptomatic group, osteophytes were found more frequently on the normally shaped condyle side than the BMC side (p<0.05). BMCs tended to be identified as an incidental finding. The presence of BMC would not lead to any TMJ symptoms or cause osseous changes.

In the symptomatic group, osteophytes were found more frequently on the normally shaped condyle side than the BMC side (p<0.05). BMCs tended to be identified as an incidental finding. The presence of BMC would not lead to any TMJ symptoms or cause osseous changes.

Full Text Available Introduction: We decided to investigate the effects of injecting Indomethacin on reducing complications of Patent Ductus Arteriosus (PDA and the need for prolonged mechanical ventilation. Methods: During this randomized clinical trial, 70 premature infants with matched gestational age and birth weight were divided into case and control groups. In the study group, intravenous indomethacin started from the first 2-12 hours of birth. All patients were followed by echocardiography at the fourth day and skull ultrasound in the second week. Results: Symptomatic PDA rate was significantly higher in the control group (25.7% vs. 0%; P≤0.001. Incidence of grade 1-3 intraventricular hemorrhage was higher in the control group and the ratio of needed time for respiratory support in the control group to the case group was approximately 2.1. Conclusion: Intravenous Indomethacin reduced the number of PDA cases and incidence of grade 2 and 3 intraventricular hemorrhage, without any short term side effects.

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

We report on a 33-year-old man with symptomatic heterotopic suprarenal splenic tissue. Heterotopic splenic tissue can often be found after posttraumatic splenectomy. It is a result of autotransplantation induced by trauma (splenosis). Additionally it can grow during embryogenic development. Such an accessory spleen is found in 10-44% of all autopsies. In this case report the patient was treated by resection due to increasing flank pain and suspected neoplasm. (orig.) [de

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.

To analyse and compare the computed tomography (CT) features of benign and malignant types of histopathologically proven cases of solitary fibrous tumours of pleura (SFTP). Retrospective analysis of preoperative CT images of 28 cases of histopathologically proven and classified SFTP from three participating institutions was performed. Patient demographics and lesion characteristics including size, borders, presence of a pedicle, extension into the fissure, attenuation, enhancement, pleural effusion, and calcifications were recorded and correlated with the final histopathological diagnosis. Type and results of preoperative biopsy were also recorded. Follow-up imaging and the clinical charts were reviewed to identify recurrence. Out of 28 cases (15 women and 13 men), 18 were proven to be benign and 10 were malignant. The mean age of patients was 58.1±15.9 and 66.5±11.8 years (p=0.1564) for benign and malignant tumours, respectively. The median (interquartile range) diameter was 6.05 (3.2-10.9) cm for benign and 15.7 (7.1-17.5) cm for malignant type tumours (p=0.0291). Tumours had lobulate borders in 28% (5/18) of benign cases and in 80% (8/10) of malignant cases (p=0.0163). Extension into adjacent fissure was seen in 22% (4/18) of benign lesions and 40% (4/10) of malignant lesions (p=0.40). A pedicle was present in 17% (3/18) of benign and 10% (1/10) of malignant lesions (p=1). Heterogeneous attenuation was present in 61% (11/18) of benign and 90% (9/10) of malignant lesions (p=0.19). Calcification was present in 17% (3/18) of benign tumours and in 70% (7/10) of malignant tumours (p=0.0113). Pleural effusion was present in 6% (1/18) of benign and 40% (4/10) of malignant lesions (p=0.04). Only 1/13 preoperative fine-needle aspirates yielded diagnosis of SFTP. Preoperative diagnosis of SFTP was made in all cases (11/11) with core biopsies. At follow-up (1-10 years, mean 3 years), local recurrence occurred in 3/6 (50%) patients with malignant SFTP and in none of the

Current management of renal angiomyolipomas (AMLs) include observation, transcatheter embolization and partial or total nephrectomy. Patients symptoms and size of the lesion are the determinants for the choice of the treatment. In general symptomatic or greater than 8 cm masses require intervention. A retrospective study of five patients presented with symptomatic lesions and treated with selective transcatheter embolization, over a 3 year period was performed in our hospital. A total of eight embolizations were performed, all on an emergency basis due to retroperitoneal bleeding or significant hematuria. Surgical intervention was necessary in one case, due to massive rebleeding on the fourth post-procedural day. Two patients rebled within 6 months and 2 years respectively, and were managed successfully with additional embolization. The remaining two patients are still asymptomatic 26 and 18 months after the successful initial result. Experience with this procedure is reported on with emphasis to the clinical outcome. It is believed that selective arterial embolization should be the standard initial therapy for symptomatic renal AMLs.

The occurrence of human herpesvirus (HHV) 6 subtypes A and B in apical periodontitis was determined. The relationship of HHV-6 subtypes to other disease associated herpesviruses, i.e., Epstein-Barr virus (EBV) and human cytomegalovirus, was also investigated. Forty apical periodontitis samples (17 symptomatic and 23 asymptomatic) and 40 healthy pulp control samples were collected. Nested polymerase chain reaction was used to detect HHV-6 DNA. HHV-6 DNA was observed in significantly higher frequencies in apical periodontitis samples than in control samples (20% vs. 2.5%; P = .03). Further classification of apical lesions revealed that subtype B of HHV-6 was significantly associated with large-sized and symptomatic lesions (P apical lesions (77%) harbored ≥1 of the tested herpesviruses: EBV was the most frequent herpesvirus (72.5%) in apical periodontitis, followed by HHV-6 (20%). Our findings suggest that EBV and HHV-6B infections can be associated with symptomatic apical periodontitis. Copyright © 2011 Mosby, Inc. All rights reserved.

One hundred eleven patients with symptomatic prosthetic joints (86 hips, 23 knees, and two shoulders) were evaluated for prosthetic loosening and infection by combined technetium-99m-MDP/gallium-67 digital subtraction imaging. Clinical correlation was based on the assessment of loosening and bacterial cultures obtained at the time of surgery in 54 patients, joint aspiration cultures obtained in 37 patients, and long-term clinical follow-up for greater than 1.5 years in an additional 15 patients. Results revealed an 80-90% predictive value of a positive test for loosening, and a 95% predictive value of a negative test for infection. However, because of the low sensitivities and specificities observed, this approach to the evaluation of symptomatic prosthetic joints does not seem cost effective

Temporary intraluminal shunt was used during 72 consecutive carotid endarterectomies (CEAs) in 61 patients (bilateral CEA in 11 patients) during October 2001 and September 2005. The medical records of these patients were retrospectively reviewed. All procedures were performed with routine shunt insertion without monitoring such as electroencephalography. Pre- and postoperative diffusion-weighted magnetic resonance (MR) imaging was used to detect ischemic complications. Postoperative angiography was performed in 70 cases to detect abnormalities such as major stenosis or dissection of the distal end. Symptomatic ischemic complication occurred in one patient at 1 month. Postoperative diffusion-weighted MR imaging detected new hyperintense lesions in three patients including the symptomatic patient. Postoperative angiography confirmed that the distal end was satisfactory in all cases. The incidence of ischemic lesions of embolic origin after CEA with routine shunt usage is acceptably low if the procedure of shunt device insertion and removal is meticulously conducted. (author)

To report the standard of care, interesting new findings and controversies about the treatment of parotid tumors. Relevant and actual studies were searched in PubMed and reviewed for diagnostics, treatment and outcome of both benign and malignant tumors. Prospective trials are lacking due to rarity of the disease and high variety of tumor subtypes. The establishment of reliable non-invasive diagnostics tools for the differentiation between benign and malignant tumors is desirable. Prospective studies clarifying the association between different surgical techniques for benign parotid tumors and morbidity are needed. The role of adjuvant or definitive radiotherapy in securing loco-regional control and improving survival in malignant disease is established. Prospective clinical trials addressing the role of chemotherapy/molecular targeted therapy for parotid cancer are needed. An international consensus on the classification of parotid surgery techniques would facilitate the comparison of different trials. Such efforts should lead into a clinical guideline.

Cholelithiasis is the second cause of hospital admissions in Chile. To study the prevalence of symptomatic gallstone disease and opportunity of cholecystectomy in La Florida, Santiago and among Mapuche Indians in Huapi Island. In the period 2000-2001, we contacted to 71% (1127 subjects) and to 61% (145 subjects) patients of La Florida and Huapi Island, respectively, that had previously participated in an epidemiological study on cholelithiasis in 1993. We defined symptomatic gallstone patients as those with a history of biliary colic. Each patient was subjected to gallbladder ultrasound. In 1993, 30-35% of gallstone patients were symptomatic (approximately 70% women). During the lapse 1993-2001, only 50% of subjects from La Florida and 25% of patients from Huapi Island were cholecystectomized (p Mapuche Indians from Huapi, cholecystectomy was indicated in 2001. After five months of the indication, only one of these subjects had been operated. Laparoscopic cholecystectomy represented 40% of all cholecystectomies performed in the National Health Service Hospitals. This study demonstrates an unacceptable high prevalence of symptomatic gallstone patients remaining non-operated in both the urban and rural communities. This reciprocally correlates with the high frequency of emergency cholecystectomies and the high incidence of gallbladder cancer among Chileans. This study contrasts negatively with the situation of Scotland, where 73.5% of cholecystectomies were laparoscopic in 1998-1999. To reach Scotland standards, the Chilean Public Health System should increase the number of cholecystectomies from 27,000 in 2001 to 57,510

Full Text Available Benign cystic mesothelioma (BCM is a rare benign disease that forms multicystic masses in the abdomen, pelvis, and retroperitoneum. It occurs predominantly in young to middle-aged women. The majority of cases were associated with a history of abdominal or pelvic operation, a history of endometriosis, and pelvic inflammatory disease. We present a unique case of BCM which is different to the previous cases. The patient was a 52-year-old man showing features of peritoneal carcinomatosis accompanied by ascites on abdominal computed tomography scans. We herein report a case of BCM misdiagnosed with peritoneal carcinomatosis.

Background An oral condition associated to psoriasis is benign migratory glossitis. The review of the literature does not show any publication about heritability in both soriasis and benign migratory glossitis and prevalence of psoriasis in the Brazilian population. Objective This research was carried out in order to determine the prevalence of psoriasis and benign migratory glossitis in the Brazilian population from a Brazilian sample, as well as the heritability in these conditions. Methods Six thousand patients were studied from the records of the outpatient dermatology department. The sample had 129 patients with cutaneous psoriasis, 399 with benign migratory glossitis without psoriasis and a control group with 5,472 patients. After data collection, the statistical analysis was made using Woolf, Chi-square and Falconer tests. Results The prevalence of psoriasis was 2.15% and the benign migratory glossitis was 7.0%. The prevalence of benign migratory glossitis in the psoriasis group was high (16.3%), and that was statistically significant. Family history in the psoriasis group was 38% for the condition itself and 2,75% for benign migratory glossitis and in the benign migratory glossitis group was 17.54% for the condition itself and 1.5% for psoriasis. The study of heritability was 38.8% for psoriasis and 36.6% for benign migratory glossitis, both with medium heritability. Study limitations This study was only in the state of São Paulo. Conclusion This is the first publication that quantifies how much of these conditions have a genetic background and how important the environmental factors are in triggering them. PMID:29364438

Objective: To explore the causes and preventive measures of symptomatic intracranial hemorrhage in 217 patients with acute cerebral ischemic stroke treated with local intra-arterial urokinase. Methods: From February 1999 to June 2004, 217 patients were treated for acute ischemic stroke with local intra-arterial urokinase in our hospital. Factors associated with symptomatic intracranial hemorrhage of intra-arterial thrombolysis were analyzed by Stepwise logistic regression to identify some factors relating the prediction symptomatic intracranial hemorrhage. Results: Symptomatic intracranial hemorrhage occurred in 8 cases (3.7%). Predictors of the symptomatic intracranial hemorrhage were the elevated systolic blood pressure before therapy (odds ratio, 1.096; 95% CI, 1.006 to 1.194) and urokinase (UK) treatment (odds ratio, 1.068 ; 95% CL, 1.053 to 1.247). Risk of secondary symptomatic intracranial hemorrhage was increased with elevated systolic blood pressure. Other factors like age, initial treating time, NIHSS, diabetes and collateral circulation did not predict the symptomatic intracranial hemorrhage respectively. Conclusions: Predictors of symptomatic intracranial hemorrhage after local intra-arterial infusion of urokinase for acute ischemic stroke were the elevated systolic blood pressure before therapy and urokinase (UK) treatment.

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

To investigate the difference in amide proton transfer (APT)-weighted signals between benign and atypical meningiomas and determine the value of APT imaging for differentiating the two. Fifty-seven patients with pathologically diagnosed meningiomas (benign, 44; atypical, 13), who underwent preoperative MRI with APT imaging between December 2014 and August 2016 were included. We compared normalised magnetisation transfer ratio asymmetry (nMTR{sub asym}) values between benign and atypical meningiomas on APT-weighted images. Conventional MRI features were qualitatively assessed. Both imaging features were evaluated by multivariable logistic regression analysis. The discriminative value of MRI with and without nMTR{sub asym} was evaluated. The nMTR{sub asym} of atypical meningiomas was significantly greater than that of benign meningiomas (2.46% vs. 1.67%; P < 0.001). In conventional MR images, benign and atypical meningiomas exhibited significant differences in maximum tumour diameter, non-skull base location, and heterogeneous enhancement. On multivariable logistic regression analysis, high nMTR{sub asym} was an independent predictor of atypical meningiomas (adjusted OR, 11.227; P = 0.014). The diagnostic performance of MRI improved with nMTR{sub asym} for predicting atypical meningiomas. Atypical meningiomas exhibited significantly higher APT-weighted signal intensities than benign meningiomas. The discriminative value of conventional MRI improved significantly when combined with APT imaging for diagnosis of atypical meningioma. (orig.)

Full Text Available Abstract Introduction Benign cystic mesothelioma or peritoneal inclusion cysts are rare benign abdominal tumors usually occurring in females of reproductive age. These cysts present as abdominopelvic pain or masses but are often found on imaging or incidentally at surgery. They are commonly associated with pelvic inflammatory disease, endometriosis, or ovarian cysts. We report what is, to the best of our knowledge, the first case of a benign cystic mesothelioma complicating a presentation of acute appendicitis. Case Presentation A 19-year-old Irish Caucasian woman presented with abdominal pain. Imaging suggested appendicitis with abscess formation. She was treated with antibiotics and scheduled for interval appendicectomy. At laparoscopy, an unusual cystic mass was found arising from the appendix. Histology revealed benign cystic mesothelioma. Conclusion We report what is, to the best of our knowledge, the first case of a benign cystic mesothelioma arising from the appendix and complicating a presentation of acute appendicitis. This is a benign pathology, but recurrences are not uncommon. Benign cystic mesothelioma should be included in the differential when investigating pelvic masses or abscesses associated with either appendicitis or pelvic inflammatory disease in women.

METHODS This is a prospective population-based single centre observational study of all patients diagnosed with benign perforated peptic ulcer; included were both gastric and duodenal ulcer patients admitted to Maharaja Yeshwantrao Hospital, Indore, between September 2013 and September 2015. Ulcers with a malignant neoplasia diagnosis verified by histology after biopsy, traumatic perforation, and perforation of age group >45 and 40 years, the incidence increased over 4 times and mortality more than 12 times compared to younger age <20 years. After 1 month followup, out of 172 discharged patients, 145 (84% patients came with symptoms resolved or having no complication. After 2 months followup, 158 (92% patients came with symptoms resolved and 166 (96% patients changed their dietary habits and lifestyle. CONCLUSION The incidence rate and mortality rate was stable. In our study, we found male preponderance, may be due to their lifestyle changes. Maximum number patients are found in age group 41-45 years. As in all previous studies, as age advances, incidence of peptic perforation also increases. Also, found strong relationship between consumption of oily or spicy food and non-vegetarian food with incidence of peptic perforation. Relation of peptic perforation with NSAIDs, smoking, and alcoholism follows same trends as in previous studies.

Dynamic computed tomography scanning of benign bone lesions: Preliminary results

International Nuclear Information System (INIS)

Levine, E.; Neff, J.R.

The majority of benign bone lesions can be evaluated adequately using conventional radiologic techniques. However, it is not always possible to differentiate reliably between different types of benign bone lesions on the basis of plain film appearances alone. Dynamic computed tomography (CT) scanning provides a means for further characterizing such lesions by assessing their degree of vascularity. Thus, it may help in distinguishing an osteoid osteoma, which has a hypervascular nidus, from a Brodie's abscess, which is avascular. Dynamic CT scanning may also help in the differentiation between a fluid-containing simple bone cyst, which is avascular, and other solid or semi-solid benign bone lesions which slow varying degrees of vascularity. However, because of the additional irradiation involved, dynamic CT scanning should be reserved for evaluation of selected patients with benign bone lesions in whom the plain film findings are not definitive and in whom the CT findings may have a significant influence on management.

Full Text Available Benign prostatic hyperplasia (BPH is a histological diagnosis associated with unregulated proliferation of connective tissue, smooth muscle and glandular epithelium. BPH may compress the urethra and result in anatomic bladder outlet obstruction (BOO; BOO may present as lower urinary tract symptoms (LUTS, infections, retention and other adverse events. BPH and BOO have a significant impact on the health of older men and health-care costs. As the world population ages, the incidence and prevalence of BPH and LUTS have increased rapidly. Although non-modifiable risk factors - including age, genetics and geography - play significant roles in the etiology of BPH and BOO, recent data have revealed modifiable risk factors that present new opportunities for treatment and prevention, including sex steroid hormones, the metabolic syndrome and cardiovascular disease, obesity, diabetes, diet, physical activity and inflammation. We review the natural history, definitions and key risk factors of BPH and BOO in epidemiological studies.

• To investigate the influence of baseline variables on the 4-year incidence of acute urinary retention (AUR), benign prostatic hyperplasia (BPH)-related surgery and overall clinical progression in men treated with tamsulosin, dutasteride, or a combination of both. • The 4-year Combination of Avodart® and Tamsulosin (CombAT) study was a multicenter, randomized, double-blind, parallel-group study of clinical outcomes in men aged ≥ 50 years with symptomatic (International Prostate Symptom Score [IPSS]≥ 12) BPH, with prostate-specific antigen (PSA) levels of ≥ 1.5 ng/mL and ≤ 10 ng/mL, and a prostate volume (PV) of ≥ 30 mL. • Eligible patients received tamsulosin 0.4 mg, dutasteride 0.5 mg, or a combination of both. • The primary endpoint was time to first AUR or BPH-related surgery. Secondary endpoints included clinical progression of BPH and symptoms. Posthoc analyses of the influence of baseline variables (including age, IPSS health-related quality of life [HRQL], PV, PSA, IPSS, peak urinary flow rate [Q(max) ] and body-mass index [BMI]) on the incidence of AUR or BPH-related surgery, clinical progression of BPH, and symptoms were performed. • There were 4844 men in the intent-to-treat population. Overall baseline characteristics were similar across all patient groups. • Regardless of baseline subgroup, the incidence of AUR or BPH-related surgery was higher in men treated with tamsulosin than in those treated with dutasteride or combined therapy. • Combined therapy was statistically better than tamsulosin in reducing the risk of AUR or BPH-related surgery in subgroups of baseline PV > 42.0 mL, in all subgroups of baseline PSA level, and all other baseline subgroups (P ≤ 0.001). • Across treatment groups, the incidence of clinical progression was highest in men with a baseline IPSS of BPH-related surgery and greater reductions in the RR of clinical progression and symptom deterioration on combined therapy or dutasteride monotherapy than

Full Text Available AIM: To evaluate the effectiveness of the Crawford tube in treating symptomatic epiphora without nasolacrimal obstruction. METHODS: A protocol was adopted for the management of symptomatic epiphora without nasolacrimal obstruction. Patients who suffered symptomatic epiphora without nasolacrimal obstruction in both eyes were included in the study. One eye was treated with Crawford tube intubation and the other eye was treated with medication therapy. Degree of watering, patient satisfaction, and symptomatic improvement were carefully evaluated by one of the authors at the end of the follow-up period, after Crawford tube removal, to ascertain functional results. RESULTS: Thirty-seven adult patients (37 eyes underwent Crawford tube intubation for functional epiphora. The mean follow-up time after removal of the tube was 14.8±4.8mo. The procedure was an overall success in 28 eyes (75.7%, with symptoms improving significantly. Two eyes (5.4% were relieved of indoor epiphora, two (5.4% had minimal epiphora outdoors, but only with wind or cold, and five (13.5% continued to experience tearing both indoors and outdoors. Thirty of the patients (81% expressed satisfaction with the procedure. CONCLUSION: Crawford tube insertion is an effective, safe, simple, and relatively noninvasive treatment strategy for functional lacrimal system obstruction.

1997-11-01

To estimate the risk of developing ovarian cancer after abdominal (total or subtotal) hysterectomy on benign indication. Prospective historical cohort study with 12.5 years of follow up. Denmark, nationwide. All Danish women (aged 0 to 99 years) having undergone hysterectomy with conservation of at least one ovary for a benign indication from 1977 to 1981 (n = 22,135). Follow up was conducted from 1977 to 1991. The reference group included all Danish women who had not undergone hysterectomy, age-standardised according to the hysterectomy group (n = 2,554,872). Registry data derived from the Danish National Register of Patients (diagnoses and operation codes) and the Civil Registration System (information about general population, including time of death). Incidence rate of ovarian cancer, lifetime risk of ovarian cancer, relative risk of ovarian cancer. Seventy-one women developed ovarian cancer on average 7.0 years after hysterectomy and 10,659 women in the reference group had ovarian cancer diagnosed after on average 6.4 years. The incidence rate of ovarian cancer was 0.27 per 1000 person-years in the group that had undergone hysterectomy and 0.34 per 1000 person-years in the general population (age-standardised). The extrapolated lifetime risk of developing ovarian cancer was 2.1% after hysterectomy and 2.7% in the general population (RR 0.78; 95% CI 0.60-0.96). The risk of ovarian cancer is lower among women who have undergone hysterectomy compared with those who have not. The protection seems to decrease with time.

Our purpose was to determine whether perfusion MR imaging can be used to differentiate benign and malignant meningiomas on the basis of the differences in perfusion of tumor parenchyma and/or peritumoral edema. A total of 33 patients with preoperative meningiomas (25 benign and 8 malignant) underwent conventional and dynamic susceptibility contrast perfusion MR imaging. Maximal relative cerebral blood volume (rCBV) and the corresponding relative mean time to enhance (rMTE) (relative to the contralateral normal white matter) in both tumor parenchyma and peritumoral edema were measured. The independent samples t-test was used to determine whether there was a statistically significant difference in the mean rCBV and rMTE ratios between benign and malignant meningiomas. The mean maximal rCBV values of benign and malignant meningiomas were 7.16{+-}4.08 (mean{+-}SD) and 5.89{+-}3.86, respectively, in the parenchyma, and 1.05{+-}0.96 and 3.82{+-}1.39, respectively, in the peritumoral edema. The mean rMTE values were 1.16{+-}0.24 and 1.30{+-}0.32, respectively, in the parenchyma, and 0.91{+-}0.25 and 1.24{+-}0.35, respectively, in the peritumoral edema. The differences in rCBV and rMTE values between benign and malignant meningiomas were not statistically significant (P>0.05) in the parenchyma, but both were statistically significant (P<0.05) in the peritumoral edema. Perfusion MR imaging can provide useful information on meningioma vascularity which is not available from conventional MRI. Measurement of maximal rCBV and corresponding rMTE values in the peritumoral edema is useful in the preoperative differentiation between benign and malignant meningiomas. (orig.)

To identify differences in health factors, neuromuscular attributes, and performance-based mobility among community-dwelling older adults with symptomatic lumbar spinal stenosis; and to determine which neuromuscular attributes are associated with performance-based measures of mobility. Cross-sectional; secondary data analysis of a cohort study. Outpatient rehabilitation center. Community-dwelling adults aged ≥65 years with self-reported mobility limitations and symptomatic lumbar spinal stenosis (N=54). Not applicable. Short Physical Performance Battery score, habitual gait speed, and chair stand test. Symptomatic lumbar spinal stenosis was classified using self-reported symptoms of neurogenic claudication and imaging. Among 430 community-dwelling older adults, 54 (13%) met criteria for symptomatic lumbar spinal stenosis. Compared with participants without symptomatic lumbar spinal stenosis, those with symptomatic lumbar spinal stenosis had more comorbidities, higher body mass index, greater pain, and less balance confidence. Participants with symptomatic lumbar spinal stenosis had greater impairment in trunk extensor muscle endurance, leg strength, leg strength asymmetry, knee flexion range of motion (ROM), knee extension ROM, and ankle ROM compared with participants without symptomatic lumbar spinal stenosis. Five neuromuscular attributes were associated with performance-based mobility among participants with symptomatic lumbar spinal stenosis: trunk extensor muscle endurance, leg strength, leg strength asymmetry, knee flexion ROM, and knee extension ROM asymmetry. Community-dwelling older adults with self-reported mobility limitations and symptomatic lumbar spinal stenosis exhibit poorer health characteristics, greater neuromuscular impairment, and worse mobility when compared with those without symptomatic lumbar spinal stenosis. Poorer trunk extensor muscle endurance, leg strength, leg strength asymmetry, knee flexion ROM, and knee extension ROM asymmetry

Symptomatic splenic hamartomas are rare in the pediatric age group, with only four previous reports in the literature. Splenic hamartoma has been reported as a solid homogeneous mass without calcification on CT and ultrasound (US), and only one previous report of the findings on MRI has been published. We report a case of a large symptomatic splenic hamartoma in a 14-year-old girl who presented with splenomegaly, pancytopenia and growth retardation. A solid mass with multiple punctate foci resembling calcifications was seen on US. The mass was heterogeneous and better demarcated on enhanced CT. Radiocolloid scintigraphy demonstrated uptake within the lesion, but less than that of normal spleen. The mass was isointense relative to normal splenic tissue on T1-weighted MRI (0.5 T) and of increased intensity with T2 weighting. At splenectomy, a red pulp hamartoma was identified, which contained nodules of hyalinization and necrosis thought to account for the punctate foci seen on US. (orig.). With 4 figs

2006-01-01

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

Background: Ovarian epithelial tumors one of the most common gynecological neoplasms; we here evaluated the presence of HPV in benign and malignant examples. Methods: In this cross-sectional study the records of 105 patients with epithelial ovarian tumors (benign and malignant) referred to Imam Hossein University Hospital from 2012 to 2015 were evaluated along with assessment of the presence of the HPV infection using PCR. Results: Among 105 patients, comprising 26 (24.8%) with malignant and 79 (75.2%) with benign lesions, the factors found to impact on malignancy were age at diagnosis, age at first pregnancy, number of pregnancies and hormonal status. However, malignancies was not related to abortion, late menopause, and early menarche. In none of the ovarian tissues (benign and malignant) was HPV DNA found. Conclusion: In this study HPV DNA could not be found in any epithelial ovarian tumors (benign and malignant) removed from 105 women; more studies with larger sample size are needed for a definite conclusion.

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

To assess the diagnostic value of dynamic perfusion MR imaging for differentiation between benign and malignant musculoskeletal lesions. Dynamic perfusion MR imaging was performed using a 3.0 T system in 32 female and 30 male patients (aged 10-90 years, mean age, 43 years). Following the assessment of the precontrast imaging, a dynamic study was performed. This dynamic technique allowed for 638 images to be obtained at 11 levels throughout the lesion. Twenty-eight lesions originated within bone (8 benign, 20 malignant), whereas 34 lesions were of soft tissue origin (22 benign, 12 malignant). The final diagnosis was histopathologically confirmed in all patients. To differentiate between benign and malignant lesions, we analyzed the four parameters: (maximal relative enhancement (MRE), time to peak (TTP), wash in rate (WI), steepest slope (SS) and the distribution of time intensity curve (TIC) patterns. The TTP, WI, and SS values of malignant lesions were statistically significant from those of benign lesions(ρ < 0.05). However, the difference for the MRE values was not statistically significant. The distribution of TIC patterns was a helpful indicator of benign or malignant state, however the difference between the two states was not significant. Dynamic perfusion MR imaging is a helpful tool in differentiating benign and malignant musculoskeletal lesions

Solitary, multiple, benign, atypical, or malignant: the "Granular Cell Tumor" puzzle.

Machado, Isidro; Cruz, Julia; Lavernia, Javier; Llombart-Bosch, Antonio

The clinical evolution and biology of granular cell tumors (GCT) are poorly understood and treatment remains an issue of discussion. The majority of GCT are benign, although some display malignant behavior. The distinction between benign, atypical, and malignant GCT is controversial due to morphological and immunohistochemical overlap and lack of consistent histological and phenotypic criteria that predict behavior. Although histological criteria may indicate increased risk of malignant evolution, some GCT with evident benign appearance exceptionally progress towards metastatic disease. In this review, we discuss current knowledge on GCT, including histologic, immunophenotypic, and molecular characteristics and differential diagnosis. We focus on the following problematic items in GCT: (1) evolution of classification, (2) neural versus non-neural GCT, (3) neoplastic versus reactive disease, (4) malignant transformation of benign GCT, and (5) multiple versus metastatic GCT. We conclude that although a Ki-67 index >10 % and the presence of mitoses and/or of necrosis are frequently associated with malignant behavior, metastasis remains the only unequivocal sign of malignancy in GCT. An infiltrative growth pattern and vascular and/or perineural invasion are not indicative of malignancy. GCT with atypical/uncertain features almost never metastasize, and many of these tumors either behave in a benign fashion or only recur locally (similar to incompletely excised benign tumors). We therefore propose that classical and atypical histological variants form a single group of GCT. GCT with various unfavorable histological features might be labeled as "GCT with increased risk of metastasis" rather than malignant GCT.

Primary benign brachial plexus tumors: an experience of 115 operated cases.

Desai, Ketan I

2012-01-01

Primary benign brachial plexus tumors are rare. They pose a great challenge to the neurosurgeon, because the majority of patients present with minimal or no neurological deficits. Radical to complete excision of the tumor with preservation of neurological function of the involved nerve is an ideal surgical treatment option with benign primary brachial plexus tumor surgery. We present a review article of our 10-year experience with primary benign brachial plexus tumors surgically treated at King Edward Memorial Hospital and P.D. Hinduja National Hospital from 2000 to 2009. The clinical presentations, radiological features, surgical strategies, and the eventual outcome following surgery are analyzed, discussed, and compared with available series in the world literature. Various difficulties and problems faced in the management of primary benign brachial plexus tumors are analyzed. Irrespective of the tumor size, the indications for surgical intervention are also discussed. The goal of our study was to optimize the treatment of patients with benign brachial plexus tumors with minimal neurological deficits. It is of paramount importance that brachial plexus tumors be managed by a peripheral nerve surgeon with expertise and experience in this field to minimize the neurological insult following surgery.

Purpose: Long-term childhood cancer survivors are at high risk of late adverse effects, including stroke. We aimed to determine the cumulative incidence of clinically validated symptomatic stroke (transient ischemic attack [TIA], cerebral infarction, and intracerebral hemorrhage [ICH]) and to quantify dose-effect relationships for cranial radiation therapy (CRT) and supradiaphragmatic radiation therapy (SDRT). Methods and Materials: Our single-center study cohort included 1362 survivors of childhood cancer that were diagnosed between 1966 and 1996. Prescribed CRT and SDRT doses were converted into the equivalent dose in 2-Gy fractions (EQD_2). Multivariate Cox regression models were used to analyze the relationship between the EQD_2 and stroke. Results: After a median latency time of 24.9 years and at a median age of 31.2 years, 28 survivors had experienced a first stroke: TIA (n=5), infarction (n=13), and ICH (n=10). At an attained age of 45 years, the estimated cumulative incidences, with death as competing risk, among survivors treated with CRT only, SDRT only, both CRT and SDRT, and neither CRT nor SDRT were, respectively, 10.0% (95% confidence interval [CI], 2.5%-17.0%), 5.4% (95% CI, 0%-17.0%), 12.5% (95% CI, 5.5%-18.9%), and 0.1% (95% CI, 0%-0.4%). Radiation at both locations significantly increased the risk of stroke in a dose-dependent manner (hazard ratios: HR_C_R_T 1.02 Gy"−"1; 95% CI, 1.01-1.03, and HR_S_D_R_T 1.04 Gy"−"1; 95% CI, 1.02-1.05). Conclusions: Childhood cancer survivors treated with CRT, SDRT, or both have a high stroke risk. One in 8 survivors treated at both locations will have experienced a symptomatic stroke at an attained age of 45 years. Further research on the pathophysiologic processes involved in stroke in this specific group of patients is needed to enable the development of tailored secondary prevention strategies.

At an attained age of 45 years, the estimated cumulative incidences, with death as competing risk, among survivors treated with CRT only, SDRT only, both CRT and SDRT, and neither CRT nor SDRT were, respectively, 10.0% (95% confidence interval [CI], 2.5%-17.0%), 5.4% (95% CI, 0%-17.0%), 12.5% (95% CI, 5.5%-18.9%), and 0.1% (95% CI, 0%-0.4%). Radiation at both locations significantly increased the risk of stroke in a dose-dependent manner (hazard ratios: HR{sub CRT} 1.02 Gy{sup −1}; 95% CI, 1.01-1.03, and HR{sub SDRT} 1.04 Gy{sup −1}; 95% CI, 1.02-1.05). Conclusions: Childhood cancer survivors treated with CRT, SDRT, or both have a high stroke risk. One in 8 survivors treated at both locations will have experienced a symptomatic stroke at an attained age of 45 years. Further research on the pathophysiologic processes involved in stroke in this specific group of patients is needed to enable the development of tailored secondary prevention strategies.

1986-01-01

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

Benign breast lesion is an important risk factor for breast cancer and elevated CA-15.3 in serum is a well established marker of breast cancer. Core-needle biopsy is now the method of choice to sample non-palpable mammographic abnormality and as well as clinically palpable lesion. To asses relationship of serum CA-15.3 with different histologic entities of benign breast lesion and usefulness of this marker in predicting breast cancer in this high risk group, a study was conducted among 140 patients who had a diagnosis of benign breast lesion and malignancy following fine needle aspiration cytology (FNAC) at department of surgery, Medical College, Kolkata between 2007 and 2009. We prospectively estimated serum CA-15.3 level in all patients. Different histologic entities of benign breast lesion, who showed serum CA-15.3 level >30U/ml underwent tru-cut biopsy to detect malignancy. Of 140 patients studied, 50 were stamped as malignancy and 90 as benign after FNAC of which 20 patients had fibroadenoma, 25 had fibro-adenoma with fibrocystic disease, 20 had fibrocystic disease with epitheliosis and 25 had fibrocystic disease with atypia. All breast cancer patients and 10 each from fibro-adenoma with fibrocystic disease, fibrocystic disease with epitheliosis and fibrocystic disease with atypia had serum CA -15.3 level>30U/ml. Thirty patients with benign breast lesion who had raised CA-15.3 underwent core-needle biopsy. Fifteen patients were detected to have intraductal carcinoma, mostly with fibrocystic disease with atypia. Clinical applicability of serum CA-15.3 to detect breast cancer should be strongly considered in management of patients with benign breast lesion and tru-cut biopsy than FNAC be done before benign breast lesion being stamped as benign. Biopsy results that are not concordant with the targeted lesion require surgical biopsy.

To evaluate the usefulness of FDG PET/CT to differentiate malignant endobronchial lesions with distal atelectasis from benign bronchial stenosis. This retrospective study reviewed 84 patients who underwent contrast-enhanced chest CT and then PET/CT and had histological (n = 81) or follow-up imaging (n = 3) confirmation. Two chest radiologists reviewed initial chest CT and determined endobronchial lesions to be malignant or benign. Two nuclear medicine physicians reviewed PET/CT for FDG uptake at the obstruction site and measured SUV. Malignancy was considered when increased FDG uptake was seen in the obstruction site, regardless of FDG within the atelectatic lung. The sensitivity, specificity and accuracy of chest CT was 95%, 48% and 84%, compared with 95%, 91% and 94% for PET/CT. Benign obstructive lesions showed statistically lower FDG uptake than malignant obstructions (benign SUV 2.5 ± 0.84; malignant SUV 11.8 ± 5.95, p < 0.001). ROC analysis showed an SUV cut-off value of 3.4 with highest sensitivity of 94% and specificity of 91%. Increased FDG PET/CT uptake at the obstruction site indicates a high probability of malignancy, while benign lesions show low FDG uptake. Careful evaluation of FDG uptake pattern at the obstruction site is helpful in the differentiation between benign and malignant endobronchial lesions. (orig.)

Factors that influence therapeutic outcomes in symptomatic gastroesophageal reflux disease.

LENUS (Irish Health Repository)

Quigley, Eamonn M M

2012-02-03

The term "symptomatic gastroesophageal reflux disease" (GERD) refers to those patients who present with the typical GERD symptoms of heartburn and regurgitation, yet do not have endoscopic evidence of esophagitis. The primary goals of managing symptomatic GERD are to control symptoms and improve quality of life. A clinical assessment of the GERD patient can identify important clinical features, such as atypical and extraesophageal symptoms for which acid-suppressive agents tend to be less effective. Performing an endoscopy can further identify the patient as having nonerosive reflux disease, erosive esophagitis, or Barrett\\'s esophagus-diagnoses which can help determine treatment but may not prove predictive of therapeutic response. Determining acid exposure through pH testing can predict therapeutic response, with those revealing an abnormal acid exposure time being more responsive to acid-suppressive therapy. However, the performance of an endoscopy and pH testing on each patient is clearly not practical. Whereas the natural history of symptomatic GERD is still largely undefined, acid-suppressive therapy appears to be the best approach available for both the short-term and long-term management of this disease.

2008-01-01

Our purpose was to determine whether perfusion MR imaging can be used to differentiate benign and malignant meningiomas on the basis of the differences in perfusion of tumor parenchyma and/or peritumoral edema. A total of 33 patients with preoperative meningiomas (25 benign and 8 malignant) underwent conventional and dynamic susceptibility contrast perfusion MR imaging. Maximal relative cerebral blood volume (rCBV) and the corresponding relative mean time to enhance (rMTE) (relative to the contralateral normal white matter) in both tumor parenchyma and peritumoral edema were measured. The independent samples t-test was used to determine whether there was a statistically significant difference in the mean rCBV and rMTE ratios between benign and malignant meningiomas. The mean maximal rCBV values of benign and malignant meningiomas were 7.16±4.08 (mean±SD) and 5.89±3.86, respectively, in the parenchyma, and 1.05±0.96 and 3.82±1.39, respectively, in the peritumoral edema. The mean rMTE values were 1.16±0.24 and 1.30±0.32, respectively, in the parenchyma, and 0.91±0.25 and 1.24±0.35, respectively, in the peritumoral edema. The differences in rCBV and rMTE values between benign and malignant meningiomas were not statistically significant (P>0.05) in the parenchyma, but both were statistically significant (P<0.05) in the peritumoral edema. Perfusion MR imaging can provide useful information on meningioma vascularity which is not available from conventional MRI. Measurement of maximal rCBV and corresponding rMTE values in the peritumoral edema is useful in the preoperative differentiation between benign and malignant meningiomas. (orig.)

To investigate the magnetic resonance (MR) enhancement patterns of symptomatic osteoporotic vertebral compression fracture (VCF) according to the fracture age, based on the successful single-level percutaneous vertebroplasty (PVP) cases. The study included 135 patients who underwent contrast-enhanced MR imaging and successful PVP from 2005 to 2010 due to a single- level osteoporotic VCF. Two radiologists blinded to the fracture age evaluated the MR enhancement patterns in consensus. The MR enhancement patterns were classified according to the enhancing proportion to the vertebral height and the presence or extent of a non-enhancing cleft within the enhancing area on sagittal plane. The Fisher' exact test, Kruskal-Wallis test and Mann-Whitney U test were performed to assess the differences in the MR enhancement patterns according to the fracture age. Symptomatic VCFs show variable MR enhancement patterns in all fracture ages. A diffuse enhancing area can be seen in not only the hyperacute and acute VCFs but also the chronic symptomatic VCFs. Symptomatic VCFs having a segmental enhancing area were all included in the hyperacute or acute stage. Most symptomatic osteoporotic VCFs had a non-enhancing cleft in the enhanced vertebral body (128/135, 94.8%). There was no statistical difference of the enhancement pattern according to the fracture age. Symptomatic VCFs show variable MR enhancement patterns in all fracture ages. The most common pattern is a non-enhancing cleft within a diffuse enhanced vertebra.

To evaluate the standardized uptake value (SUV) of [ 18 F]2-deoxy-2-fluoro-d-glucose at positron emission tomography (FDG-PET) for preoperative differential diagnosis between benign and malignant soft tissue masses.Design One hundred and fourteen soft tissue masses (80 benign, 34 malignant) were examined by FDG-PET prior to tissue diagnosis. The SUVs were calculated and compared between benign and malignant lesions and among different histologic subgroups which included three or more cases. There was a statistically significant difference in SUV between benign (1.80±1.42 [SD]) and malignant (4.20±3.16) soft tissue masses in total (P<0.0001). However, a considerable overlap in SUV was observed between many benign and malignant lesions. Liposarcomas (2.16±1.72) and synovial sarcomas (1.60±0.43) did not show significantly higher SUV than any benign lesions. Metastases (4.23±2.35) showed no statistically significant difference in SUV as compared with schwannomas (1.75±0.84), desmoids (2.77±1.32), sarcoidosis (3.62±1.53), or giant cell tumors of tendon sheath (GCT of TS; 5.06±1.63). Even malignant fibrous histiocytomas (5.37±1.40) could not be differentiated from sarcoidosis or GCT of TS, based on the SUV. A large accumulation of FDG can be observed in both benign and malignant histiocytic, fibroblastic, or neurogenic lesions. SUV at conventional FDG-PET is limited to differentiating benign from malignant soft tissue masses, when all kinds of histologic subtypes are included. (orig.)

BACKGROUND--Autonomic neuropathy provides a mechanism for the absence of symptoms in silent myocardial ischaemia, but characterisation of the type of neuropathy is lacking. AIM--To characterise and compare autonomic nerve function in patients with silent and symptomatic myocardial ischaemia. METHODS AND RESULTS--The Valsalva manoeuvre, heart rate variation (HRV) in response to deep breathing and standing, lower body negative pressure, isometric handgrip, and the cold pressor test were performed by patients with silent (n = 25) and symptomatic (n = 25) ambulatory ischaemia and by controls (n = 21). No difference in parasympathetic efferent function between patients with silent and symptomatic ischaemia was recorded, but both had significantly less HRV in response to standing than the controls (p < 0.005 for silent and p < 0.01 for symptomatic). Patients with silent ischaemia showed an increased propensity for peripheral vasodilatation compared with symptomatic patients (p < 0.02) and controls (p < 0.04). Impaired sympathetic function was found in patients with pure silent ischaemia (n = 4) compared with the remaining patients with silent ischaemia whose pain pathways were presumed to be intact. CONCLUSIONS--Patients with silent ischaemia and pain pathways presumed to be intact have an enhanced peripheral vasodilator response, and if this applied to the coronary vasculature it could provide a mechanism for limiting ischaemia to below the pain threshold. Patients with pure silent ischaemia have evidence of sympathetic autonomic dysfunction. Images PMID:8297687

Our goal was to assess the value of surgical excision of benign papillomas of the breast diagnosed on percutaneous core biopsy by determining the frequency of upgrade to malignancies and high risk lesions on a final surgical pathology. We reviewed 67 patients who had biopsies yielding benign papilloma and underwent subsequent surgical excision. Surgical pathology of the excised lesions was compared with initial core biopsy pathology results. 54 patients had concordant benign core and excisional pathology. Cancer (ductal carcinoma in situ and invasive ductal carcinoma) was diagnosed in five (7%) patients. Surgery revealed high-risk lesions in 8 (12%) patients, including atypical ductal hyperplasia, atypical lobular hyperplasia, and lobular carcinoma in situ. Cancer and high risk lesions accounted for 13 (19%) upstaging events from benign papilloma diagnosis. Our data suggests that surgical excision is warranted with core pathology of benign papilloma

There are limited data on utility of diffusion-weighted imaging (DWI) in the evaluation of pediatric liver lesions. To determine whether qualitative and quantitative DWI can be used to differentiate benign and malignant pediatric liver lesions. We retrospectively reviewed MRIs in children with focal liver lesions to qualitatively evaluate lesions noting diffusion restriction, T2 shine-through, increased diffusion, hypointensity on DWI and apparent diffusion coefficient (ADC) maps, and intermediate signal on both, and to measure ADC values. Pathology confirmation or a combination of clinical, laboratory and imaging features, and follow-up was used to determine final diagnosis. We included 112 focal hepatic lesions in 89 children (median age 11.5 years, 51 female), of which 92 lesions were benign and 20 malignant. Interobserver agreement was almost perfect for both qualitative (kappa 0.8735) and quantitative (intraclass correlation coefficient [ICC] 0.96) diffusion assessment. All malignant lesions showed diffusion restriction. Most benign lesions other than abscesses were not restricted. There was significant association of qualitative restriction with malignancy and non-restriction with benignancy (Fisher exact test P<0.0001). Mean normalized ADC values of malignant lesions (1.23 x 10{sup -3} mm{sup 2}/s) were lower than benign lesions (1.62 x 10{sup -3} mm{sup 2}/s; Student's t-test, P<0.015). However, there was significant overlap of ADC between benign and malignant lesions, with wide range for each diagnosis. Receiver operating characteristic (ROC) analysis revealed an area under the curve (AUC) of 0.63 for predicting malignancy using an ADC cut-off value of ≤1.20 x 10{sup -3} mm{sup 2}/s, yielding a sensitivity of 78% and a specificity of 54% for differentiating malignant from benign lesions. Qualitative diffusion restriction in pediatric liver lesions is a good predictor of malignancy and can help to differentiate between benign and malignant lesions

To compare the galactographic findings of malignant and benign disease in patients with pathologic nipple discharge and to analyze the features suggesting malignancy. In 24 patients in whom pathologic nipple discharge had occurred, the findings of preoperative galactography were correlated with those of pathology. Nine of the 24 cases were malignant and the other 15 were benign. Intraductal calcification occurred in five malignant cases (56%) and two (13%) which were benign. Seven malignant cases (78%) involved the segmental ducts, and in eight (89%), the peripheral ducts below the subsegmental duct were involved. Five benign cases (33%) involved the lactiferous sinus, seven (47%) the segmental duct, and two (13%) the subsegmental duct. Distal duct dilatation occurred in four benign cases (27%), while ductal stenosis was noted in six cases (67%) and ductal distortion in seven (78%). A malignant tumor appeared as a multiple (n=5, 56%) or irregular (n=5, 56%) filling defect, and a benign tumor as a single (n=12, 80%), oval (n=6, 40%) or lobular (n=4, 27%) filling defect. At galactography, a malignant tumor frequently appeared as an irregular multiple intraductal filling defect in a peripheral duct. A benign tumor, on the other hand, appeared as an oval or lobular single lesion. The presence of ductal stenosis, distortion and intraductal microcalcifications not opacified by contrast material suggest possible malignancy.

Benign lichenoid keratosis is a cutaneous entity that consists of a nonpruritic papule or slightly indurated plaque that is histologically characterized by a band-like inflammatory infiltrate with interface involvement. The purpose of this study was to investigate the clinical and histopathologic features of benign lichenoid keratosis localized on the face. Fourteen benign lichenoid keratosis patients diagnosed clinically and histopathologically in our clinic during the 10-year period from 2002 to 2012 were studied. Thirteen female and 1 male patients were included. The mean age at diagnosis was 46.5 years. The color of most of the lesions was brown (10 cases, 71%). The cheek was the most commonly involved area (10 cases, 71%). All of the lesions were single. There were 9 (64%) flat lesion cases and 5 (36%) raised lesion cases. Most patients denied having any symptoms; 3 had mild pruritus. The histopathological findings indicated that all the cases exhibited lichenoid inflammatory infiltrate obscuring the dermal-epidermal junction and vacuolar alteration of basal cell layer. The lesions showed focal parakeratosis (79%), melanophages (79%), hyperkeratosis (71%), and necrotic keratinocytes (71%). Solar elastosis (50%) and acanthosis (43%) were also seen frequently. Diagnosis of benign lichenoid keratosis should be made by a combination of clinical manifestations and histopathological findings. In particular, benign lichenoid keratosis should be considered if a middle-aged patient presents a solitary asymptomatic brown lesion on the face. We think benign lichenoid keratosis may be a specific disorder rather than the inflammatory stage of regressing solar lentigines, large cell acanthoma or reticulated seborrheic keratosis.

Objectives To examine the prevalence and incidence, clinical presentation, societal impact and comorbid conditions of benign paroxysmal positional vertigo (BPPV) in the general population. Methods Cross‐sectional, nationally representative neurotological survey of the general adult population in Germany with a two stage sampling design: screening of 4869 participants from the German National Telephone Health Interview Survey 2003 (response rate 52%) for moderate or severe dizziness or vertigo, followed by validated neurotological interviews (n = 1003; response rate 87%). Diagnostic criteria for BPPV were at least five attacks of vestibular vertigo lasting <1 min without concomitant neurological symptoms and invariably provoked by typical changes in head position. In a concurrent validation study (n = 61) conducted in two specialised dizziness clinics, BPPV was detected by our telephone interview with a specificity of 92% and a sensitivity of 88% (positive predictive value 88%, negative predictive value 92%). Results BPPV accounted for 8% of individuals with moderate or severe dizziness/vertigo. The lifetime prevalence of BPPV was 2.4%, the 1 year prevalence was 1.6% and the 1 year incidence was 0.6%. The median duration of an episode was 2 weeks. In 86% of affected individuals, BPPV led to medical consultation, interruption of daily activities or sick leave. In total, only 8% of affected participants received effective treatment. On multivariate analysis, age, migraine, hypertension, hyperlipidaemia and stroke were independently associated with BPPV. Conclusion BPPV is a common vestibular disorder leading to significant morbidity, psychosocial impact and medical costs. PMID:17135456

Preoperative discrimination between benign and malignant soft tissue tumors is critical for the prevention of excess application of magnetic resonance imaging and biopsy as well as unplanned resection. Although ultrasound, including power Doppler imaging, is an easy, noninvasive, and cost-effective modality for screening soft tissue tumors, few studies have investigated reliable discrimination between benign and malignant soft tissue tumors. To establish a modality for discrimination between benign and malignant soft tissue tumors using ultrasound, we extracted the significant risk factors for malignancy based on ultrasound information from 40 malignant and 56 benign pathologically diagnosed soft tissue tumors and established a scoring system based on these risk factors. The maximum size, tumor margin, and vascularity evaluated using ultrasound were extracted as significant risk factors. Using the odds ratio from a multivariate regression model, a scoring system was established. Receiver operating characteristic analyses revealed a high area under the curve value (0.85), confirming the accuracy of the scoring system. Ultrasound is a useful modality for establishing the differential diagnosis between benign and malignant soft tissue tumors.

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

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.

This study aimed to preliminarily investigate the feasibility of intravoxel incoherent motion (IVIM) theory in the differential diagnosis of benign and malignant thyroid nodules. Forty-five patients with 56 confirmed thyroid nodules underwent preoperative routine magnetic resonance imaging and IVIM diffusion-weighted imaging. The histopathologic diagnosis was confirmed by surgery. Apparent diffusion coefficient (ADC), perfusion fraction f, diffusivity D, and pseudo-diffusivity D* were quantified. Independent samples t test of IVIM-derived metrics were conducted between benign and malignant nodules. Receiver-operating characteristic analyses were performed to determine the optimal thresholds as well as the sensitivity and specificity for differentiating. Significant intergroup difference was observed in ADC, D, D*, and f (p < 0.001). Malignant tumors featured significantly lower ADC, D and D* values and a higher f value than that of benign nodules. The ADC, D, and D* could distinguish the benign from malignant thyroid nodules, and parameter f differentiate the malignant tumors from benign nodules. The values of the area under the curve for parameter ADC, D, and D* were 0.784 (p = 0.001), 0.795 (p = 0.001), and 0.850 (p < 0.001), separately, of which the area under the curve of f value was the maximum for identifying the malignant from benign nodules, which was 0.841 (p < 0.001). This study suggested that ADC and IVIM-derived metrics, including D, D*, and f, could potentially serve as noninvasive predictors for the preoperative differentiating of thyroid nodules, and f value performed best in identifying the malignant from benign nodules among these parameters.

We report our experience with 43 retroperitoneal laparoscopic nephrectomy for benign kidney disease. All patients had a poor function from obstructive uropathology and renal atrophy. None of these patients had a previous lumbotomy. Retroperitoneoscopy was performed with 4 trocar port technique in a lateral position. The retroperitoneal space is created by using a Gaur's balloon made of sterile glove. The approach to vascular pedicle was done posteriorly and vessels were clipped by metal and Hem-o-lock (Weck Closure Systems, North Carolina, USA) clips. The sample was intact extracted in an Endo-Bag prolonging one trocar incision. Median operative time was 160 minutes and median blood loss was 200 mL. Four cases (9%) were converted to open surgery: one case due to bleeding and 3 cases due to technical difficulties regarding perirenal adherences. Most patients (39) checked out from the Hospital in day two. Four of them were left over 3 days due to wound complications. Retroperitoneoscopy offers a safe, effective and reproductive access to nephrectomy for benign pathologies.

Since its introduction in 1992, laparoscopic adrenalectomy (LA) has become the technique of choice in the surgical treatment of both secreting or non-secreting benign adrenal pathology. Although traditionally, laparoscopic approach was recommended only for tumor sizes less than 6-8 cm--as larger tumors were known to have an increased risk of malignancy--the currently growing experience and improvement of surgical techniques has allowed for an extension of the therapeutic indication, as shown by the recent case report of LA use for a benign 22 cm tumor (1). We report the case of a young patient operated in our Department for a benign 20 cm adrenal tumor for which laparoscopic "hand-assisted" adrenalectomy yielded a good postoperative outcome and minimal complications.

Full Text Available Background: Fine-needle aspiration biopsy can very reliably discriminate between benign and malignant thyroid tumors. The role of additional intraoperative frozen section to guide intraoperative management was questioned.Methods: A retrospective analysis of all thyroid resections at our department between 2000 and 2004 was performed.Results: 420 patients with benign thyroid lesions underwent surgical resections. 169 lobectomies and 251 total thyroidectomies were performed and 57 (13.5 % thyroid cancers discovered (mostly papillary carcinomas. 54 frozen sections were performed and sensitivity rate of 11.1 % and specificity rate of 97.8 % was estimated.Conclusions: Our data supports the fact that intraoperative frozen section is not sensitive enough to substantially add to preoperative fine-needle aspiration biopsy, even with more selective use. We conclude that routine use of frozen section is not cost-effective in surgery of the benign thyroid and can therefore be abandoned.

Full Text Available Multiple sclerosis (MS is the commonest cause of disability in young adults. While there is increasing choice and better treatments available for delaying disease progression, there are still, very few, effective symptomatic treatments. For many patients such as those with primary progressive MS (PPMS and those that inevitably become secondary progressive, symptom management is the only treatment available. MS related symptoms are complex, interrelated, and can be interdependent. It requires good understanding of the condition, a holistic multidisciplinary approach, and above all, patient education and empowerment.

Anxiety manifests itself in the obsession of unobtainable idealised forms of diversity as well as in the uncertainty associated with the traumatic experience of always falling short of what is desired in an object...... – the experience of failed diversity. Conclusively, we discuss the productive potential of the power of lack. The impossibility of diversity is what, at once, conditions the possibility of diversity. We therefore suggest that the symptomatic anxiety provoked by the lack should be enjoyed in order to engage...

2012-10-01

Full Text Available Abstract Background Between 8% and 22% of female carriers of DMD mutations exhibit clinical symptoms of variable severity. Development of symptoms in DMD mutation carriers without chromosomal rearrangements has been attributed to skewed X-chromosome inactivation (XCI favouring predominant expression of the DMD mutant allele. However the prognostic use of XCI analysis is controversial. We aimed to evaluate the correlation between X-chromosome inactivation and development of clinical symptoms in a series of symptomatic female carriers of dystrophinopathy. Methods We reviewed the clinical, pathological and genetic features of twenty-four symptomatic carriers covering a wide spectrum of clinical phenotypes. DMD gene analysis was performed using MLPA and whole gene sequencing in blood DNA and muscle cDNA. Blood and muscle DNA was used for X-chromosome inactivation (XCI analysis thought the AR methylation assay in symptomatic carriers and their female relatives, asymptomatic carriers as well as non-carrier females. Results Symptomatic carriers exhibited 49.2% more skewed XCI profiles than asymptomatic carriers. The extent of XCI skewing in blood tended to increase in line with the severity of muscle symptoms. Skewed XCI patterns were found in at least one first-degree female relative in 78.6% of symptomatic carrier families. No mutations altering XCI in the XIST gene promoter were found. Conclusions Skewed XCI is in many cases familial inherited. The extent of XCI skewing is related to phenotype severity. However, the assessment of XCI by means of the AR methylation assay has a poor prognostic value, probably because the methylation status of the AR gene in muscle may not reflect in all cases the methylation status of the DMD gene.

Objective In Italy, colorectal screening programmes using the faecal immunochemical test from ages 50 to 69 every two years have been in place since 2005. We aimed to measure the incidence of interval cancers in the two years after a negative faecal immunochemical test, and compare this with the pre-screening incidence of colorectal cancer. Methods Using data on colorectal cancers diagnosed in Italy from 2000 to 2008 collected by cancer registries in areas with active screening programmes, we identified cases that occurred within 24 months of negative screening tests. We used the number of tests with a negative result as a denominator, grouped by age and sex. Proportional incidence was calculated for the first and second year after screening. Results Among 579,176 and 226,738 persons with negative test results followed up at 12 and 24 months, respectively, we identified 100 interval cancers in the first year and 70 in the second year. The proportional incidence was 13% (95% confidence interval 10-15) and 23% (95% confidence interval 18-25), respectively. The estimate for the two-year incidence is 18%, which was slightly higher in females (22%; 95% confidence interval 17-26), and for proximal colon (22%; 95% confidence interval 16-28). Conclusion The incidence of interval cancers in the two years after a negative faecal immunochemical test in routine population-based colorectal cancer screening was less than one-fifth of the expected incidence. This is direct evidence that the faecal immunochemical test-based screening programme protocol has high sensitivity for cancers that will become symptomatic.

Full Text Available Purpose. The recurrence of CBD stone is still observed in a considerable number of patients. The study was to evaluate the risk factors for recurrence of symptomatic CBD stone in patients who underwent cholecystectomy after the removal of CBD stone. Methods. The medical records of patients who underwent removal of CBD stone with subsequent cholecystectomy were reviewed. The risk factors for the recurrence of symptomatic CBD stone were compared between the recurrence and the nonrecurrence group. Results. The mean follow-up period was 40.6 months. The recurrence of symptomatic CBD stones was defined as the detection of bile duct stones no sooner than 6 months after complete clearance of CBD stones, based on symptoms or signs of biliary complication. 144 patients (68 males, 47.2% were finally enrolled and their mean age was 59.8 (range: 26~86 years. The recurrence of CBD stone occurred in 15 patients (10.4%. The mean period until first recurrence was 25.9 months. The presence of type 1 or 2 periampullary diverticulum and multiple CBD stones were the independent risk factors. Conclusion. For the patients with type 1 or 2 periampullary diverticulum or multiple CBD stones, careful followup is needed for the risk in recurrence of symptomatic CBD stone.

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.

Removal of symptomatic craniofacial titanium hardware following craniotomy: Case series and review

Directory of Open Access Journals (Sweden)

Sheri K. Palejwala

2015-06-01

Full Text Available Titanium craniofacial hardware has become commonplace for reconstruction and bone flap fixation following craniotomy. Complications of titanium hardware include palpability, visibility, infection, exposure, pain, and hardware malfunction, which can necessitate hardware removal. We describe three patients who underwent craniofacial reconstruction following craniotomies for trauma with post-operative courses complicated by medically intractable facial pain. All three patients subsequently underwent removal of the symptomatic craniofacial titanium hardware and experienced rapid resolution of their painful parasthesias. Symptomatic plates were found in the region of the frontozygomatic suture or MacCarty keyhole, or in close proximity with the supraorbital nerve. Titanium plates, though relatively safe and low profile, can cause local nerve irritation or neuropathy. Surgeons should be cognizant of the potential complications of titanium craniofacial hardware and locations that are at higher risk for becoming symptomatic necessitating a second surgery for removal.

The purpose of this study was to evaluate the differential diagnostic value of 18 F-fluorodeoxy glucose positron emission tomography/computed tomography ( 18 F-FDG PET/CT) for benign and malignant testicular lesions. The PET/CT scans of 53 patients with testicular lesions confirmed by biopsy or surgical pathology were retrospectively analyzed. There were 32 cases of malignant tumors and 21 cases of benign lesions. Differences in the maximum standardized uptake value (SUVmax) measurements and the SUVmax lesion/background ratios between benign and malignant lesions were analyzed. The diagnostic value of this PET/CT modality for the differential diagnosis of benign versus malignant testicular lesions was calculated. The differences in the SUVmax measurements and the SUVmax lesion/background ratios between benign and malignant lesions were statistically significant (SUVmax: Z=-4.295, p=0.000; SUVmax lesion/background ratio: Z=-5.219, p=0.000); specifically, both of these indicators were higher in malignant lesions compared to benign lesions. An SUVmax of 3.75 was the optimal cutoff value to differentiate between benign and malignant testicular lesions. The diagnostic sensitivity, specificity, accuracy, positive predictive value, and negative predictive value of this PET/CT modality in the differential diagnosis of benign versus malignant testicular lesions were 90.6%, 80.9%, 86.8%, 87.9%, and 85.0%, respectively. 18 F-FDG PET/CT can accurately identify benign and malignant testicular lesions.

Endoscopic Management of Benign Esophageal Strictures.

Science.gov (United States)

Ravich, William J

2017-08-24

This paper presents the author's approach to esophageal dilation. It offers a tailored approach to the application of dilation to specific types of esophageal stenotic lesions. In patients with inflammatory stricture, recent studies confirm the importance of treating the underlying inflammatory condition in order to decrease the rate of recurrence. The paper reviews some of the novel techniques that have been suggested for the treatment of refractory benign esophageal strictures, including incisional therapy, stenting, or the injection steroids or antifibrotic agents. The endoscopist who treats esophageal strictures must be familiar with the tools of the dilation and how they are best applied to specific types of stenotic lesions. If inflammation is present, effective management requires treatment of the inflammatory process in addition to mechanical dilation of the stenotic lesion. Controlled trials of novel approaches to treatment of refractory benign esophageal strictures are limited and will be necessary to determine efficacy.

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

To determine an association between sonographically determined contractility with the symptomatic or silent nature of gallstone. Adult gallstone patients without (group I) and with biliary symptoms (group II) were compared with age and gender-matched controls. Demographic data, body mass index, risk factors, size, number and mobility of gallstone, gallbladder wall thickness (GBWT), volume and Ejection Fraction (EF) were determined on ultrasound before and after a standardized fatty meal (BFM and AFM). Demographic data, risk factors and gallstone characteristics were analyzed by Pearson Chi-square test and the gallbladder characteristics were analyzed by One-way ANOVA and Post Hoc tests by multiple comparisons on SPSS 11 with significance p=0.05. The gallbladder contractility as measured by changes in wall thickness and volume changes BFM and AFM, and ejection fraction was similar in controls and asymptomatic cholelithiasis groups and significantly reduced in symptomatic patients (p<.001). Multiparity (p=0.002), female gender (p=0.018), age less than 50 years (0.05), impacted calculi (p=0.001), multiple calculi (<.001) and calculi 5 mm (p<0.001) were associated with pain. A sluggishly emptying gallbladder was more significantly associated with symptomatic cholelithiasis compared to controls and asymptomatic cholelithiasis state in this series. Consideration of age, gender, impaction of calculi, number and size of calculi is important in causing symptom state and management options. (author)

Incidence of lung cancer in patients with idiopathic pulmonary fibrosis (IPF) is known to be higher than that in general population. However, it is difficult to discriminate pulmonary nodule in patients with IPF, because underlying IPF can be expressed as lung nodules. We evaluated the diagnostic performance of FDG PET in discriminating lung nodule in patients with IPF. We retrospectively reviewed 28 lung nodules in 16 subjects (age; 67.53 ± 9.83, M:F = 14:2). Two patients had previous history of malignant cancer (small cell lung cancer and subglottic cancer). The diagnostic criteria on chest CT were size, morphology and serial changes of size. FDG PET was visually interpreted, and maximal SUV was calculated for quantitative analysis. From 28 nodules, 18 nodules were interpreted as benign nodules, 10 nodules as malignant nodules by histopathology or follow-up chest CT. The sensitivity and specificity of FDG PET were 100% and 94.4%, while those of CT were 70.0% and 44.4% respectively. Malignant nodule was higher maxSUV than that of benign lung nodules (7.68 ± 3.96 vs 1.22 ± 0.65, p < 0.001). Inflammatory lesion in underlying IPF was significantly lower masSUV than that of malignant nodules (1.80 ± 0.43, p < 0.001). The size of malignant and benign nodule were 23.95 ± 10.15 mm and 10.83 ± 5.23 mm p < 0.01) FDG PET showed superior diagnostic performance to chest CT in differentiating lung nodules in patients with underlying IPF. FDG PET could be used to evaluate suspicious malignant nodule detected by chest in patients with IPF

There are limited data on utility of diffusion-weighted imaging (DWI) in the evaluation of pediatric liver lesions. To determine whether qualitative and quantitative DWI can be used to differentiate benign and malignant pediatric liver lesions. We retrospectively reviewed MRIs in children with focal liver lesions to qualitatively evaluate lesions noting diffusion restriction, T2 shine-through, increased diffusion, hypointensity on DWI and apparent diffusion coefficient (ADC) maps, and intermediate signal on both, and to measure ADC values. Pathology confirmation or a combination of clinical, laboratory and imaging features, and follow-up was used to determine final diagnosis. We included 112 focal hepatic lesions in 89 children (median age 11.5 years, 51 female), of which 92 lesions were benign and 20 malignant. Interobserver agreement was almost perfect for both qualitative (kappa 0.8735) and quantitative (intraclass correlation coefficient [ICC] 0.96) diffusion assessment. All malignant lesions showed diffusion restriction. Most benign lesions other than abscesses were not restricted. There was significant association of qualitative restriction with malignancy and non-restriction with benignancy (Fisher exact test Pbenign and malignant lesions, with wide range for each diagnosis. Receiver operating characteristic (ROC) analysis revealed an area under the curve (AUC) of 0.63 for predicting malignancy using an ADC cut-off value of ≤1.20x10 -3  mm 2 /s, yielding a sensitivity of 78% and a specificity of 54% for differentiating malignant from benign lesions. Qualitative diffusion restriction in pediatric liver lesions is a good predictor of malignancy and can help to differentiate between benign and malignant lesions, in conjunction with conventional MR sequences. Even though malignant lesions demonstrated significantly lower ADC values than benign lesions, the use of quantitative diffusion remains limited in its utility for distinguishing them because of the

We wanted to determine the multidetector computed tomography (MDCT) findings for differentiating benign ulcers from malignant ones. 18 clinicopathologically proven benign ulcers that had been detected by both endoscopy and MDCT were the focus of this study. 26 ulcerative advanced gastric cancers and 26 early gastric cancers with ulceration, all of which had been surgically proven, were selected as a control group. Five of the 26 early gastric cancers that were confined to the mucosa and that were not detected on CT were excluded in this study. The following CT findings were reviewed by two radiologists; ulcer size, the degree of enhancement and the thickness of inner enhancing layer in the ulcer base, the total thickness and the enhancing inner layer thickness in the largest part of the thickened ulcer mound, the presence of ulcer that projected beyond the healthy lumen, and the presence of perigastric fat infiltration and perigastric lymphadenopathy. An indiscernible thin-walled ulcer base (less than 1.5 mm) and suboptimal enhancement of the ulcer base for the discrimination of benign gastric ulcers from the malignant gastric ulcers showed sensitivities of 100% (18/18) and 78% (14/18), respectively, with specificities of 98% (46/47) and 92% (43/47), respectively. Ulcer projection was more significantly present in benign ulcer (13/18, 72%) than in the malignant gastric ulcers (7/47, 15%). The enhancing inner layer thickness in the ulcer mound was significantly greater in the AGC (mean; 7.4 mm) than in the benign gastric ulcers (mean, 2.2 mm). There were insignificant differences for ulcer size, total thickness of the ulcer mound, the perigastric fat infiltration and perigastric lymphadenopathy between the benign and malignant gastric ulcers. MDCT is an additional helpful diagnostic tool when benign gastric ulcers are histologically difficult to distinguish from malignant gastric ones.

The purpose of this study was to evaluate the usefulness of diffusion-weighted MRI in distinguishing different components and in differentiating benign from malignant musculoskeletal tumors. Fifty-seven patients with musculoskeletal tumors underwent MR at our institution from October 1999 to April 2002. We evaluated 57 tumors (9 bone tumors and 48 soft tissue tumors). All tumors were classified into 8 groups (myxomatous, fibrous, cystic, cartilaginous, fatty components, hematomas, other benign tumors, and other malignant tumors). MR examinations were performed with a 1.5-Tesla system. Diffusion-weighted single-shot echo planer imaging (EPI) images were obtained in all patients. Apparent diffusion coefficients (ADCs) were calculated by using b factors of 0 and 1,000 sec/mm 2 . ADC values of myxomatous, cystic, and cartilaginous components were significantly higher than those of other tumors. In cartilaginous tumors, malignant tumor ADC values (2.33±0.44) were higher than those of benign tumors (2.13±0.13). However, there was no significant difference between benign and malignant tumors. Except for high-intensity components on T1-weighted imaging and low or homogeneously very high intensity components on T2-weighted imaging, there was a significant difference in ADC between malignant (1.35±0.40) and benign (1.97±0.50) tumors. Within the limited number of cases, there was a significant difference in ADC between malignant and benign tumors. (author)

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

A 71-year-old woman, in whom computed tomography revealed a solitary mass shadow at the base of the left lung, underwent resection of the mass. Histopathological examination showed estrogen receptor-positive leiomyoma cells growing in cords and mixed with glandular structures composed of alveolar cells. These findings led to a diagnosis of benign metastatic leiomyoma. Benign metastatic leiomyoma is a rare disease in which histologically benign uterine leiomyoma cells metastasize to different sites of the body. However, in this patient, the presence of uterine myoma was not confirmed in the past or at present. She had a history of cervical conization, which suggests that a small amount of the leiomyoma component contained in cervical tissue may have been forced into blood vessels during surgical manipulation, causing lung metastasis.

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

To evaluate the value of combining the detection of intratumoral macroscopic fat and hemorrhage in the differentiation of the benign from malignant solid renal masses.Conventional magnetic resonance imaging (MRI), chemical shift (CS)-MRI, and susceptibility-weighted imaging were performed in 152 patients with 152 solid renal masses, including 48 benign and 104 malignant masses all pathologically confirmed. The presence of macroscopic fat detected by CS-MRI and hemorrhage detected by susceptibility-weighted imaging were evaluated in all masses. The rates of macroscopic fat and hemorrhage observed between benign and malignant masses were compared by a χ test. All masses found to contain macroscopic fat with or without hemorrhage were considered to be benign. The remaining masses (without macroscopic fat) found not to contain hemorrhage were considered to be benign. Only those found to contain hemorrhage alone were considered to be malignant. The evaluation indexes for differentiating and forecasting the benign and malignant masses were calculated.Significant differences in the rate of macroscopic fat (observed in 85.42% of benign masses vs. 0% of malignant masses) and hemorrhage (observed in 4.17% of benign masses vs. 95.19% of malignant masses) were measured in the benign and malignant groups (P benign and malignant masses were 96.05%, 95.19%, and 97.92%, respectively, and the accuracy and error rate of forecasting the benign and malignant masses were 95.39% and 4.61%, respectively.Combining the detection intratumoral macroscopic fat and hemorrhage can be used to differentiate the benign from malignant solid renal masses.
