    Full Text Available Background. To validate feasibility, efficacy, and safeness of laparoscopic treatment of benign adnexal diseases through a single transumbilical access (LESS in a prospective series of patients. Methods. A prospective clinical trial including 30 women has been conducted at the Division of Gynecology of Catholic University of Sacred Hearth of Rome. Patients underwent different laparoscopic procedures by LESS utilizing a multiport trocar and conventional straight laparoscopic instrumentation. Intra and perioperative outcome has been reported. Results. Ten mono/bilateral adnexectomies and 20 cystectomies have been performed by LESS approach. Laparoscopic procedures were completed through a single access in 28 cases (93.4%. No major intra- or postoperative complications were observed. Mean hospital stay was 1.3 days. Conclusions. LESS approach is feasible to treat benign adnexal disease with a very low conversion rate and no early or late complications. More clinical data are needed to confirm these advantages compared to standard laparoscopic technique.

    The purpose of this study was to prospectively assess the contribution of diffusion-weighted MR imaging (DWI) for characterizing complex adnexal masses. Seventy-seven women (22-87 years old) with complex adnexal masses (30 benign and 47 malignant) underwent MR imaging including DWI before surgery. Conventional morphological MR imaging criteria were recorded in addition to b{sub 1,000} signal intensity and apparent diffusion coefficient (ADC) measurements of cystic and solid components. Positive likelihood ratios (PLR) were calculated for predicting benignity and malignancy. The most significant criteria for predicting benignity were low b{sub 1,000} signal intensity within the solid component (PLR = 10.9), low T2 signal intensity within the solid component (PLR = 5.7), absence of solid portion (PLR = 3.1), absence of ascites or peritoneal implants (PLR = 2.3) and absence of papillary projections (PLR = 2.3). ADC measurements did not contribute to differentiating benign from malignant adnexal masses. All masses that displayed simultaneously low signal intensity within the solid component on T2-weighted and on b{sub 1,000} diffusion-weighted images were benign. Alternatively, the presence of a solid component with intermediate T2 signal and high b{sub 1,000} signal intensity was associated with a PLR of 4.5 for a malignant adnexal tumour. DWI signal intensity is an accurate tool for predicting benignity of complex adnexal masses. (orig.)

    The discrimination between benign and malignant adnexal masses in ultrasound images represents one of the most challenging problems in gynecologic practice. In the study described here, a new method for automatic discrimination of adnexal masses based on a neural networks approach was tested. The proposed method first calculates seven different types of characteristics (local binary pattern, fractal dimension, entropy, invariant moments, gray level co-occurrence matrix, law texture energy and Gabor wavelet) from ultrasound images of the ovary, from which several features are extracted and collected together with the clinical patient age. The proposed technique was validated using 106 benign and 39 malignant images obtained from 145 patients, corresponding to its probability of appearance in general population. On evaluation of the classifier, an accuracy of 98.78%, sensitivity of 98.50%, specificity of 98.90% and area under the curve of 0.997 were calculated.

    Full Text Available Laparoscopic surgery has been demonstrated as a valid approach in almost all gynaecologic procedures including malignant diseases. Benefits of the minimally invasive approach over traditional open surgery have been well demonstrated in terms of minimal perioperative morbidity and reduced postoperative pain and hospital stay duration, with consequent quick postoperative recovery (Medeiros et al. (2009. Single-port surgery resurfaced in gynaecology surgery in recent years and renewed interest among other surgeons and within the industry to develop this field (Podolsky et al. (2009. Patient satisfaction is emerging as an increasingly important measure of quality which represents a complex entity that is dependent on patient demographics, comorbidities, disease, and, to a large extent, patient expectations (Tomlinson and Ko (2006. It can be broadly thought to refer to all relevant experiences and processes associated with health care delivery (Jackson et al. (2001. In this study we aim to compare single-port surgery (SPS with conventional laparoscopy in terms of patient satisfaction using the EORTC IN-PATSAT32 questionnaire. We also evaluate the main surgical outcomes of both minimally invasive approaches.

    Currently available robotic surgical systems appear to be particularly suited for use in benign diseases of the gastrointestinal system. Minimally invasive operations for foregut conditions, such as gastroesophageal reflux disease and achalasia, require excellent visibility and precise tissue dissection. Benign lower gastrointestinal diseases, including inflammatory bowel disease and diverticulitis, also can be approached using robotic assistance. Disadvantages include expense and the loss of tactile feedback. Early clinical results are promising.

    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

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

    The aim of the study was to evaluate differences in the use of radioactive iodine in the treatment of benigh thyroid disease in Denmark. A questionnaire was distributed to all departments in Denmark which administer radioiodine in the treatment of benign thyroid disease (n=20). Radioiodine is used for patients with toxic nodular goitre and for patients with relapse of toxic diffuse goitre. Four departments did not use radioiodine for volume reduction in non-toxic goitre. Patient information's included very different recommendations regarding cautions in relation to radioiodine treatment. Radioiodine is widely used in the treatment of benign thyroid disease. We recommend a national standardization of the cautions in relation to radioiodine treatment. (au)

    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.

    Full Text Available BACKGROUND AND OBJECTIVES: In this modern era of change in dietary habits, life style and increased awareness about the self-breast examination, the rate of detection of breast lump is on increasing trend. Due to its enormous anatomical and physiological changes during different phases of life, breast diseases are not uncommon. The benign conditions however are also associated with morbidity and are of great concern to the patient. This study was carried out to compare the age distribution and proportion of various benign breast tumors, taking into account the various factors associated with them. A correlation of clinical and histopathological diagnosis was drawn and thus the specificity of clinical diagnosis. METHODS: Prospective review of 50 patients from General Surgery department, who are found to have benign breast tumors on clinico-pathological examination, Bowring and Lady Curzon Hospitals, attached to Bangalore Medical College & Research Institute, Bangalore selected during the period from October 2011 to April 2014 on random basis. Post-operative follow up done to note the complications both in hospital and after discharge. RESULTS: Patients predominantly presented with lump in breast were fibroadenoma and fibrocystic disease. Ductal papilloma, phyllodes tumor and lipoma were also encountered. All patients underwent FNAC. Treatment was mostly surgical in the form of excision, simple mastectomy, microdochotomy and wide local excision. All the specimens were subjected to histopathological examination. Using clinical diagnosis, FNAC and histopathology increased the accuracy of diagnosis. Cases followed up and no recurrence was found. CONCLUSIONS: Commonest benign breast tumor found was Fibroadenoma (78%. Majority of the patients were in the active reproductive age group. Fibroadenoma was more common in 2nd decade of life, whereas fibrocystic disease found in 3rd decade. Majority of benign breast lesions presented with painless lump. FNAC

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

    As a minimally invasive treatment of esophageal achalasia per-oral endoscopic myotomy( POEM) was developed in 2008. More than 1,100 cases of achalasia-related diseases received POEM. Success rate of the procedure was more than 95%(Eckerdt score improvement 3 points and more). No serious( Clavian-Dindo classification III b and more) complication was experienced. These results suggest that POEM becomes a standard minimally invasive treatment for achalasia-related diseases. As an off-shoot of POEM submucosal tumor removal through submucosal tunnel (per-oral endoscopic tumor resection:POET) was developed and safely performed. Best indication of POET is less than 5 cm esophageal leiomyoma. A novel endoscopic treatment of gastroesophageal reflux disease (GERD) was developed. Anti-reflux mucosectomy( ARMS) is nearly circumferential mucosal reduction of gastric cardia mucosa. ARMS is performed in 56 consecutive cases of refractory GERD. No major complications were encountered and excellent clinical results. Best indication of ARMS is a refractory GERD without long sliding hernia. Longest follow-up case is more than 10 years. Minimally invasive treatments for esophageal benign diseases are currently performed by therapeutic endoscopy.

METHODS A prospective study was conducted at the Department of Obstetrics and Gynaecology of P K Das Institute of Medical Sciences from January 2013 to December 2013. An effort was made to perform hysterectomies vaginally in women with benign or premalignant conditions in the absence of prolapse. A suspected adnexal pathology, endometriosis, immobility of uterus, uterus size more than 16 weeks was excluded from the study. Vaginal hysterectomy was done in usual manner. In bigger size uterus, morcellation techniques like bisection, debulking, coring, myomectomy, or combination of these were used to remove the uterus. Data regarding age, parity, uterine size, estimated blood loss, length of operation, intraoperative and postoperative complications and hospital stay were recorded. RESULTS A total of 100 cases were selected for non-descent vaginal hysterectomy. Among them, 97 cases successfully underwent nondescent vaginal hysterectomy. Majority of the patients (55% were in age group 40-45 yrs. Four patients were nulligravida and eight patients had previous LSCS. Uterine size was ≤ 12 weeks in 84 cases and > 12-16 weeks in 16 cases. Commonest indication was leiomyoma of uterus (43%. Mean duration of surgery was 70±20.5 minutes. Mean blood loss was 150±65 mL. Reasons for failure to perform NDVH was difficulty in opening pouch of Douglas in two cases because of adhesions and in one case there was difficulty in reaching the fundal myoma which prevented the uterine descent. Intra–operatively, one case had bladder injury (1% that had previous 2 LSCS. Postoperatively, complications were minimal which included postoperative fever (11%, UTI (8% and vaginal cuff infection was (4%. Mean hospital stay was 3.5 days.

METHODS: Cross-sectional study, in which 105 women with adnexal tumors and indication for laparotomy/laparoscopy were included. All women were treated at a teaching hospital in the state of São Paulo between November 2009 and March 2011. All patients underwent a structured interview about the occurrence of 18 symptoms associated with ovarian cancer. The interview included the severity, frequency, and duration of these symptoms in the 12 months prior to the first medical consultation. The CA125 levels and the ultrasound classification of the tumors were also evaluated. We calculated for each symptom the prevalence ratio with 95% confidence intervals. The golden-standard was the result of the pathological examination of the surgical specimens. RESULTS: Of the 105 women included, 75 (71.4% had benign tumors and 30 (28.6% had malignant ones. In women with malignant tumors, the most frequent symptoms were: abdominal bloating (70%, increased abdominal size (67%, pelvic pain (60%, menstrual irregularity (60%, swelling (53%, abdominal pain (50%, backache (50%, and early repletion (50%.

    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.

The treatment depends upon the grade and stage of the disease. High grade lymhoma requires treatment with systemic chemotherapy whereas the localized low grade (extranodal marginal zone lymphoma can be successfully managed with local radiotherapy. Chlamydia psittaci infection is associated with low grade ocular lymphoma; however there is wide geographic variation in the strength of this association. Blanket antibiotic therapy is not advised unless there is proof of an infective agent.

    To evaluate the ability of quantitative dynamic contrast-enhanced magnetic resonance imaging (DCE-MRI) to differentiate malignant from benign adnexal tumours. Fifty-six women with 38 malignant and 18 benign tumours underwent MR imaging before surgery for complex adnexal masses. Microvascular parameters were extracted from high temporal resolution DCE-MRI series, using a pharmacokinetic model in the solid tissue of adnexal tumours. These parameters were tissue blood flow (F{sub T}), blood volume fraction (Vb), permeability-surface area product (PS), interstitial volume fraction (Ve), lag time (Dt) and area under the enhancing curve (rAUC). Area under the receiver operating curve (AUROC) was calculated as a descriptive tool to assess the overall discrimination of parameters. Malignant tumours displayed higher F{sub T}, Vb, rAUC and lower Ve than benign tumours (P < 0.0001, P = 0.0006, P = 0.04 and P = 0.0002, respectively). F{sub T} was the most relevant factor for discriminating malignant from benign tumours (AUROC = 0.86). Primary ovarian invasive tumours displayed higher F{sub T} and shorter Dt than borderline tumours. Malignant adnexal tumours with associated peritoneal carcinomatosis at surgery displayed a shorter Dt than those without peritoneal carcinomatosis at surgery (P = 0.01). Quantitative DCE-MRI is a feasible and accurate technique to differentiate malignant from benign adnexal tumours and could potentially help oncologists with management decisions. (orig.)

    Mature teratoma of the ovary is the most common primary ovarian tumor accounting for 15% (10%-20%) of all ovarian neoplasms. Skin and skin adnexal structures are the most common elements identified in mature teratomas. Benign and malignant skin tumors can arise in ovarian teratomas, the most common being epithelial tumors. Melanocytic and adnexal tumors developing in a teratoma are rare and can be easily overlooked. We report 3 cases and review melanocytic and skin adnexal tumors encountered in ovarian teratomas.

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

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

    A 44-year-old man with upper abdominal pain, diarrhea and 25 kg weight loss since 3 months ago was admitted. He had a history of dyspepsia and peptic ulcer disease 4 months before admission. Gastroduodenal endoscopy and upper gastrointestinal series with barium study were done. Biopsies and CT-scan ruled out malignancies. Endoscopy and radiology studies revealed a duodenocolic fistula. He underwent right hemicolectomy, fistula en bloc excision, and distal gastrectomy surgery with gastrojejunostomy and ileocolic anastomosis. Radiologic modalities are necessary before surgery. Surgery is the only curative treatment in benign cases and reconstruction method is dependent on patient's situation.

  12. Hepatic steatosis: A benign disease or a silent killer

    Institute of Scientific and Technical Information of China (English)

    2008-01-01

    Steatosis is a common feature of many liver diseases, namely non-alcoholic steatohepatitis (NASH) and hepatitis C virus (HCV) infection, but the pathogenic mechanisms differ. Insulin resistance (IR), a key feature of metabolic syndrome, is crucial for NASH development, associated with many underlying genetically determined or acquired mitochondrial and metabolic defects and culminates to inflammation and progression to fibrosis. This may have potential implications for new drug therapy. In HCV-related disease, steatosis impacts both fibrosis progression and response to treatment. Steatosis in HCV-related disease relates to both viral factors (HCV genotype 3), and host factors (alcohol consumption, overweight, hyperlipidemia, diabetes). Among others, IR is a recognized factor. Hepatic steatosis is reported to be associated with disturbance in the signaling cascade of interferon and downregulation of its receptors. Thus, hepatic steatosis should not be considered a benign feature, but rather a silent killer.

  13. Breast cancer. Part 1: Awareness and common benign diseases.

    Harmer, Victoria

    Breast cancer is the most common cancer for women in the United Kingdom and topic on which there is much information. This article discusses the principles behind breast awareness and breast health, detailing common benign breast diseases that cause disproportionate anxiety. The NHS Breast Screening Programme is celebrating 20 years of screening this year, and in all randomized controlled trials of women aged 50 and over, mortality from breast cancer is reduced in those offered screening compared with unscreened controls (although the reduction is not statistically significant in all trials). Once a breast cancer is diagnosed, the different characteristics and stage of the disease can be identified through histopathology and scans. These factors will be discussed later in this article, including illustrating if a cancer is hormone sensitive or HER-2 positive, for example. These factors enable clinicians to recommend a treatment pathway suitable for each individual.

    Full Text Available Benign Breast Disease (BBD, commonest cause of morbidity in females due to breast diseases, still offers therapeutic challenge. Several drug therapies (with Evening Primrose Oil, Danazol etc have been tried, but none made gold standard. Reports on effect of Cox-2 inhibitors are scarce. This randomized control trial aims at determination of effect of Cox- inhibitors (Celecoxib in BBD in comparison to Evening Primrose Oil (EPO . Celecoxib showed better reduction in lump size (in 80% than EPO group (in 50%. Pain reduction was excellent in COX -2 groups as compared to EPO group. Recurrence rate was also lower in Celecoxib group at 10 weeks. Side effects were almost nil in both the groups. Celecoxib is better than EPO in the management of BBD. Short course therapy with COX-2 inhibitors gives good pain relief, greater reduction in lump size, low recurrence with minimum side effects.

    Holmium-166 (Ho-166), one of the lanthanide radionuclides and produced upon neutron irradiation of naturally abundant Ho-165, is an almost ideal radionuclide for therapeutic purposes. The reasons for this are: (1) it is a strong beta emitter (Emax = 1.86 MeV) with maximum range in soft-tissue of 8.4 mm, (2) it has a short physical half-life of 26.9 hours, (3) it emits a gamma photon (81 keV, 5.4%) that can be used for external imaging of post-therapy monitoring purpose. Clinical trials of Ho-166 therapy for various malignancies and benign conditions are under way in Korea, {sup 166}Ho(NO{sub 3}) solution is applied into the balloon following percutaneous transfemoral coronary angioplasty (PTCA) in an attempt to inhibit neointimal hyperplasia incident to ballooning injury. Chitosan obtained by deacetylation of naturally abundant chitin is complexed with Ho-166 by mixing acidic chitosan solution at a room temperature with higher than 99% labelling yield. The Ho-166 complex is stable in vitro and vivo. Another benign condition, rheumatoid joint disease, is treated by local administration of the agent into the knee joint for radionuclide synovectomy. Malignant conditions being treated with Ho-166-CHICO (chitosan complex) include cystic brain tumours, malignant ascites and pleural effusion, hepatocellular carcinomas, recurrent melanoma and recurrent rectal carcinomas. Our clinical experience with Ho-166 or Ho-166-CHICO therapy is presented. (orig.)

    With regard to the treatment of differentiated non-medullary thyroid carcinoma, there is controversy over whether radiation from a diagnostic radioiodine ({sup 131}I) application really does have a suppressive effect on the uptake of subsequent therapeutic {sup 131}I (so-called thyroid stunning). However, inherent difficulties in exact remnant/metastatic tissue volumetry make it difficult to quantify how much diagnostic {sup 131}I is actually absorbed (absorbed energy dose) and hence to decide whether a threshold absorbed dose exists beyond which such stunning would occur. Since in benign thyroid disease the target volume can be readily quantified by ultrasonography, we sought to determine definitely whether stunning of thyroid cells occurs upon a second application of radioiodine 4 days following the first one. We therefore studied 171 consecutive patients with benign thyroid disease (diffuse goitre, Graves' disease, toxic nodular goitre) who received two-step {sup 131}I therapy during a single in-patient stay. For application of both calculated {sup 131}I activities we performed kinetic dosimetry of {sup 131}I uptake, effective half-life and absorbed dose. At the second application, patients showed significant stunning (a 31.7% decrease in {sup 131}I uptake, from 34.7%{+-}15.4% at first application to 23.7%{+-}12.3% at second application, P<0.0005) without a significant difference in effective half-life (4.9{+-}1.3 vs 5.0{+-}1.7 days, P>0.2). ANOVA showed that the extent of stunning was influenced significantly only by the absorbed energy dose at first application (F=13.5, P<0.0005), while first-application {sup 131}I activity, target volume, gender and thyroid function had no influence (all F{<=}0.71, all P>0.4). There was no significant correlation between extent of thyroid stunning and first-application {sup 131}I activity (r=0.07, P>0.3), whereas there was a highly significant correlation between thyroid stunning and first absorbed energy dose (r=0.64, P

    Full Text Available Objective: Adnexal masses are the most common reason for gynecologic surgery in adolescent patients. Early detection and adequate management of adnexal lesions are very important for saving lives and preserving fertility. In this study, we analyzed the clinical characteristics of 106 Turkish adolescent women who underwent surgery for adnexal masses. Methods: The study included 106 patients aged ≤20 years that underwent surgery for adnexal masses at our hospital between January 2008 and December 2013. Clinical profiles were retrospectively collected from the hospital medical records. The records were analyzed for demographic profiles, initial symptoms, preoperative radiologic findings, operative approach, surgical procedure, pathology findings, and the maximum diameter of the adnexal mass. Results: The age of the patients ranged from 12 to 20 years (median, 18.8 years. The most common initial symptom in these patients was abdominal pain (56.6%. Non-neoplastic ovarian lesions in the patients included 7 (6.6% corpora hemorrhagica, 10 (9.4% corpus luteal cysts, 4 (3.8% paratubal cysts, and 7 (6.6% simple cysts. Benign neoplastic tumors included 20 (18.9% mature cystic teratomas (i.e., dermoid tumors, 10 (9.4% serous cystadenomas, 1 (0.9% mucinous cystadenomas, and 7 (6.6% endometriomas. The most common surgical approach and procedure were laparoscopy (67.0% and cystectomy (60.4%, respectively. Conclusion: Laparoscopy can be performed in many adolescent patients and conservative, adnexal-sparing surgery should be encouraged for all patients. Ovarian-preserving techniques should be a priority when surgery is performed for benign masses in order to optimize future fertility potential. J Clin Exp Invest 2015; 6 (2: 96-101

    2015-01-01

    Over the past 30 years, the field of endoscopy haswitnessed several advances. With the advent ofendoscopic mucosal resection, removal of large mucosallesions have become possible. Thereafter, endoscopicsubmucosal resection was refined, permitting en blocremoval of large superficial neoplasms. Such techniqueshave facilitated the development of antirefluxmucosectomy, a promising novel treatment for gastroesophagealreflux. The introduction and use of overthe scope clips has allowed for endoscopic closureof defects in the gastrointestinal tract, which weretraditionally treated with surgical intervention. With thedevelopment of per-oral endoscopic myotomy (POEM),the treatment of achalasia and spastic disorders ofthe esophagus have been revolutionized. From thesubmucosal tunnelling technique developed for POEM,Per oral endoscopic tumor resection of subepithelialtumors was made possible. Simultaneously, advancesin biotechnology have expanded esophageal stentingcapabilities with the introduction of fully covered metaland plastic stents, as well as biodegradable stents.Once deemed a primarily diagnostic tool, endoscopy hasquickly transcended to a minimally invasive interventionand therapeutic tool. These techniques are reviewedwith regards to their application to benign disease ofthe esophagus.

    The version 3 of the guideline for radioiodine therapy for benign thyroid diseases presents first of all a revision of the version 2. The chapter indication for radioiodine therapy, surgical treatment or antithyroid drugs bases on an interdisciplinary consensus. The manifold criteria for decision making consider the entity of thyroid disease (autonomy, Graves' disease, goitre, goitre recurrence), the thyroid volume, suspicion of malignancy, cystic nodules, risk of surgery and co-morbidity, history of subtotal thyroidectomy, persistent or recurrent thyrotoxicosis caused by Graves' disease including known risk factors for relapse, compression of the trachea caused by goitre, requirement of direct therapeutic effect as well as the patient's preference. Because often some of these criteria are relevant, the guideline offers the necessary flexibility for individual decisions. Further topics are patients' preparation, counseling, dosage concepts, procedural details, results, side effects and follow-up care. The prophylactic use of glucocorticoids during radioiodine therapy in patients without preexisting ophthalmopathy as well as dosage and duration of glucocorticoid medication in patients with preexisting ophthalmopathy need to be clarified in further studies. The pragmatic recommendations for the combined use of radioiodine and glucocorticoids remained unchanged in the 3{sup rd} version. (orig.)

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

    The thyroid gland was one of the first organs imaged in nuclear medicine, beginning in the 1940s. Thyroid scintigraphy is based on a specific phase or prelude to thyroid hormone synthesis, namely trapping of iodide or iodide analogues (ie, Tc99m pertechnetate), and in the case of radioactive iodine, eventual incorporation into thyroid hormone synthesis within the thyroid follicle. Moreover, thyroid scintigraphy is a reflection of the functional state of the gland, as well as the physiological state of any structure (ie, nodule) within the gland. Scintigraphy, therefore, provides information that anatomical imaging (ie, ultrasound, computed tomography [CT], magnetic resonance imaging) lacks. Thyroid scintigraphy plays an essential role in the management of patients with benign or malignant thyroid disease. In the former, the structure or architecture of the gland is best demonstrated by anatomical or cross-sectional imaging, such as ultrasound, CT, or even magnetic resonance imaging. The role of scintigraphy, however, is to display the functional state of the thyroid gland or that of a clinically palpable nodule within the gland. Such information is most useful in (1) patients with thyrotoxicosis, and (2) those patients whose thyroid nodules would not require tissue sampling if their nodules are hyperfunctioning. In neoplastic thyroid disease, thyroid scintigraphy is often standard of care for postthyroidectomy remnant evaluation and in subsequent thyroid cancer surveillance. Planar radioiodine imaging, in the form of the whole-body scan (WBS) and posttherapy scan (PTS), is a fundamental tool in differentiated thyroid cancer management. Continued controversy remains over the utility of WBS in a variety of patient risk groups and clinical scenarios. Proponents on both sides of the arguments compare WBS with PTS, thyroglobulin, and other imaging modalities with differing results. The paucity of large, randomized, prospective studies results in dependence on consensus

    2006-01-01

    Background Laparoscopy has been accepted for years as a management of benign ovarian tumors. The aim of this study was to estimate the feasibility and safety of laparoscopy in diagnosis and management of adnexal masses.Methods A total of 2083 patients with benign adnexal mass were treated by laparoscopy at Peking Union Medical College Hospital from January 2000 to December 2003. Their clinical data were reviewed retrospectively. All the adnexal masses suspicious of malignancy at the time of laparoscopy were sent for frozen section evaluation intraoperatively. The rates of unexpected intracystic vegetation and low malignant potential (LMP) tumor or malignancy were investigated. The sensitivity, specificity, positive predictive value, and negative predictive value of laparoscopic diagnosis for LMP or ovarian malignancies were calculated. The ratios were compared by Chi-square test and the continuous variables were tested using two-tailed t test. Results Of the 2083 patients, 16 had LMP or invasive tumors (0.77%), among which 14 were diagnosed histologically intraoperatively and 2 postoperatively. Fifty-five (2.6%) of the 2083 patients had unexpected intracystic vegetations. Their frozen sections showed benign tumors in 41 (74.5%), LMP tumors in 8 (14.5%), and focal invasive ovarian cancers (stage Ic) in 6 (10.9%). The final pathological diagnosis were benign tumors in 41 (74.5%), LMP tumors 7 (12.7%), and focal invasive ovarian cancers (stage Ic) in 7 (12.7%). Laparoscopy achieved a sensitivity of 87.5%, specificity of 98%, positive predictive value of 25.5%, and negative predictive value of 99.9% in the diagnosis of ovarian malignancies. 2067 cases with benign adnexal masses underwent laparoscopy successfully. No conversion to laparotomy, or intra- and postoperative complications in this series. Of the 16 patients with LMP or invasive ovarian cancer, seven underwent laparoscopic surgery including immediate staging laparoscopy in 3. The mean follow-up was 17.3 months

    Our purpose is to clarify the diffusion-weighted (DW) imaging findings of adnexal torsion. We retrospectively analyzed the DW imaging findings in 11 consecutive patients with surgical confirmation of adnexal torsion. We assessed signal intensity of the adnexal mass and fallopian tube thickening, and the location of abnormal signal intensity within the adnexal mass. On DW imaging, thickening of the fallopian tube was apparent as abnormal signal intensity in 8 of 11 patients. Abnormal signal intensity was inhomogeneous in 7 of 8 patients. Abnormal signal intensity on DW imaging was observed in 10 of 11 adnexal masses, and in the walls of 7 out of 8 adnexal cystic lesions. In adnexal torsion, DW imaging showed abnormal signal intensity in the thickened fallopian tube and in the wall of cystic ovarian lesions. These findings would be feasible to diagnose adnexal torsion.

    Radioiodine therapy of benign thyroid diseases (focal = [toxic adenoma], multifocal, disseminated autonomy, Grave's disease or clinical relevant goitre) needs to be and can be performed individually for each patient. Most frequently a radioiodine test is performed applying a small activity of iodine-131 ({sup 131}I). The paper discusses some protocols for pre- or posttherapeutic dosimetry and discusses their advantages and disadvantages. All are based on the volumetry of the target tissue as well as the radioiodine kinetics in the target volume what may be represented by maximum uptake and half life of iodine retention in the thyroid. Possible disturbances and measuring uncertainties of these parameters are presented and discussed. In spite of the discussed uncertainties in dosimetry, due to its high therapeutic width radioiodine therapy is a very successful procedure to cure hyperthyroidism or to reduce goitre volume with only little side effects.

    Patients and Methods: The presented data refer to a retrospective univariant examination of 67 patients, which have been treated for IPP with soft X-rays in the Dermatological Clinic of the Technical University of Munich between 1990 and 1995. The aim of the study was to examine, how far a progression of the disease can be stopped with soft X-rays and how the pain symptomatic is reduced. Results: In 58 of 67 examined patients (86.6%) a progression of the disease could be stopped. 25 out of 67 patients (37.3%) complained of pain before therapy. This symptomatic mostly improved totally in 21 patients (84% of the patients with pain). A complete or partial dissolution of the indurations was to be noticed in 41 of 70 indurations (58.6%). In 23 of 60 patients (38.3%) an improvement or totally regression of the deviation was observed. It could be shown that therapeutic outcome significantly correlates to a shorter duration of anamnesis (p < 0.05), smaller plaque size (p < 0.025) and a tendency to lower age of the patients. Conclusion: Radiotherapy of Morbus Peyronie is extremely effective and has a low rate of side effects. (orig.)

    Background and objective: To examine whether clinically benign multiple sclerosis patients (BMS) show similar losses of their global N-acetylaspartate (NAA) neuronal marker relative to more clinically disabled patients of similar disease duration. Methods: The whole-brain NAA concentration (WBNAA) was acquired with whole-head non-localizing proton MR spectroscopy. Fractional brain parenchymal volume (fBPV), T{sub 2} and T{sub 1} lesion loads, were obtained from the MRI in: (i) 24 BMS patients: 23.1 ± 7.2 years disease duration, median Expanded Disability Status Scale (EDSS) score of 2.0 (range: 0–3); (ii) 26 non-benign MS patients (non-BMS), 24.5 ± 7.4 years disease duration, median EDSS of 4.0 (range: 3.5–6.5); (iii) 15 healthy controls. Results: Controls’ 12.4 ± 2.3 mM WBNAA was significantly higher than the BMS's and non-BMS's 10.5 ± 2.4 and 9.9 ± 2.1 mM (both p < 0.02), but the difference between the patients’ groups was not (p > 0.4). Likewise, the controls’ 81.2 ± 4.5% fBPV exceeded the BMS and non-BMS's 77.0 ± 5.8% and 76.3 ± 8.6% (p < 0.03), which were also not different from one another (p > 0.7). BMS patients’ T{sub 1}-hypointense lesion load, 2.1 ± 2.2 cm{sup 3}, was not significantly different than the non-BMS's 4.1 ± 5.4 cm{sup 3} (p > 0.08) and T{sub 2}-hyperintense loads: 6.0 ± 5.7 cm{sup 3} and 8.7 ± 7.8 cm{sup 3}, were also not different (p > 0.1). Conclusions: WBNAA differentiates normal controls from MS patients but does not distinguish BMS from more disabled MS patients of similar disease duration. Nevertheless, all MS patients who remain RR for 15+ years suffered WBNAA loss similar to the average RR MS population at fourfold shorter disease duration suggesting relative global neuronal sparing or leveling-off of the neurodegeneration rate.

    Full Text Available The aim of this study was to investigate phenotypic profile of B lymphocytes in peripheral blood of the patients with chronic endometritis and adnexitis. The study involved 89 women in their reproductive age (18 to 45 years with chronic endometritis (48 cases and adnexitis (41 cases. Ninety-eight healthy agematched women participated as a control group. Phenotypic B-cell subpopulations were analyzed by flow cytometry performed with direct immunofluorescent staining of peripheral cells from whole blood using the following antibody panel: CD5-FITC/CD23-PE/CD19-ECD/CD45-PC5/CD27-PC7. A significantly reduced B-lymphocyte content was revealed in peripheral blood of women with chronic endometritis and adnexitis. The reduced cell numbers occurred due to reduced B2 (main fraction of B-lymphocytes and as B1 cells (minor fraction which determines insufficient reactivity of specific humoral immune response, including immune reactions at the mucous membranes. However, percentage of B2-lymphocytes was decreased only in endometriosis, whereas patients with adnexitis showed decrease in both relative and absolute counts of this B cell subpopulation. A decreased content of naive B-cells in the peripheral blood is another feature of the B cell phenotypic profile in chronic endometritis and adnexitis. Moreover, the drop of the naive B-cell levels in patients with adnexitis proved to be more pronounced than in persons with endometritis. Expression of CD23- antigen (a low-affinity receptor for IgE has been investigated as a functional marker of B cells. All the studied peripheral B cell subpopulations expressing CD23 were decreased in the patients with chronic endometritis. The numbers of different B cell fractions expressing CD23 antigen were also reduced in the women with chronic adnexitis as compared to the levels detected in patients with chronic endometritis. Alterations of the B-cell immunity were more pronounced in chronic adnexitis, due to more extensive

    Full Text Available Cutaneous adnexal neoplasms are rare tumors that display differentiation in different ways. The aim of this study is, to present embryonic developmental properties and to determine the way of differentiation of adnexal neoplasms by evaluating the immunohistochemical expression of various markers.Forty-seven cases with adnexal tumors enrolled in this study. Histopathologic groups of these 47 cases were: 15 (32% hair follicle tumors, 11 (23.4% sebaceous tumors, 8 (17% apocrine tumors, and 13 (27.6% eccrine tumors. CK5-6, CK6, CK7, CK8, CK10, CK19, GCDFP-15, carcinoembryonic antigen, epithelial membrane antigen and S100 protein expressions were examined by immunohistochemical methods.As a result of this immunohistochemical study it was concluded that the expression of CK5-6 and CK8 carries more importance than other markers in determining certain types of differentiation of hair follicle tumors. It was also determined that, epithelial membrane antigen expression is important for the diagnosis of sebaceous tumors and the markers like CK8, CK10 and carcinoembryonic antigen may aid for the same purpose as well. It was found that, GCDFP-15 as well as CK5-6 expressions are significant for apocrine tumors, and carcinoembryonic antigen reaction as well as CK8 positivity will aid in determining differentiation of eccrine tumors. The presence of similar CK6 expression in all kinds of adnexal tumors has demonstrated that this marker is useless in differential diagnosis.

    Full Text Available Objective. To reevaluate the long-term effectiveness and safety of laparoscopy in benign ovarian pathology. Materials and Methods. 1522 women with benign adnexal cysts, laparoscopically treated in the 3rd Department of Ob/Gyn, General University hospital “Attikon” and “Lito” Maternity Hospital between July 1998 and December 2006, were included. Results. The diagnosis in 1222 (80,6% cases was endometriosis of the ovary, 60 (4% hydrosalpinx, 51 (3,3% serous cystadenomas, 44 (2,9% dermoid ovarian cyst, 38 (2,5% borderline tumors, 35 (2,3% unruptured follicles, and 33 (2,2% paraovarian cysts. In 174 cases (11,5% laparoscopy was converted to laparotomy due to technical difficulties or suspicion of cancer. In particular, laparotomy was performed in 119 (8% women due to severe adhesions and 18 (1,2% women due to bleeding that could not be controlled safely by laparoscopy. In 36 (2,4% women frozen section during operation revealed malignancy and laparoscopy was converted to laparotomy. A few operative complications were recorded like post-op fever, small hematomas at the trocar entries. Conclusions. Laparoscopic surgery seems to offer significant advantages such as reduced hospital stay, less adverse effects, better quality of life, and superior vision especially on surgical treatment of cases like endometriosis.

    Full Text Available Meckel’s diverticulum is a real diverticulum located at the antimesenteric portion of intestinal loops and including all layers of the intestinal wall. It is the most common congenital anomaly of the gastrointestinal tract, and its incidence is 1–3%. Many asymptomatic cases are diagnosed when complications occur. A 23-year-old female patient applied to gynaecology emergency clinic with pelvic pain complaint. Laparotomy was performed with the diagnosis of acute abdomen because the physical examination and imaging studies did not exclude tuboovary pathology. Giant Meckel’s diverticulitis and ischemic bowel loops that had been torsion were observed. Obstruction is the most common complication and generally originates from inflammation, adhesions, intussusception and omphalo-mesenteric band. In this case, it was seen that mobilized diverticulitis can be complicated without any fibrous band or adhesion to adjacent organs. This case supports that there can be torsion of bowel in free Meckel’s diverticulum. Meckel’s diverticulum settled in the pelvic region can make a clinical manifestation that is difficult to distinguish from adnexal diseases. It should be kept in mind for cases that start with pelvic pain, form adnexal pathology suspicion and cause an acute abdomen.

    Full Text Available Abstract Background Hepato-biliary tract lithiasis is common and present either as pain or as asymptomatic on abdominal ultrasonography for other causes. Although the DNA of Helicobacter species are identified in the gallbladder bile, tissue or stones analyzed from these cases, still a causal relationship could not be established due to different results from different geographical parts. Methods A detailed search of pubmed and pubmedcentral was carried out with key words Helicobacter and gallbladder, gallstones, hepaticolithiasis, cholelithiasis and choledocholithiasis, benign biliary diseases, liver diseases. The data was entered in a data base and meta analysis was carried out. The analysis was carried out using odds ratio and a fixed effect model, 95% confidence intervals for odds ratio was calculated. Chi square test for heterogeneity was employed. The overall effect was calculated using Z test. Results A total of 12 articles were identified. One study used IgG for diagnosis while others used the PCR for Ure A gene, 16 S RNA or Cag A genes. A couple of studies used culture or histopathology besides the PCR. The cumulative results show a higher association of Helicobacter with chronic liver diseases (30.48%, and stone diseases (42.96%(OR 1.77 95% CI 1.2–2.58; Z = 2.94, p = 0.003, the effect of each could not be identified as it was difficult to isolate the effect of helicobacter due to mixing of cases in each study. Conclusion The results of present meta analysis shows that there is a slight higher risk of cholelithiasis and benign liver disease (OR 1.77, however due to inherent inability to isolate the effect of stone disease from that of other benign lesions it is not possible to say for sure that Helicobacter has a casual relationship with benign biliary disease or stone disease or both.

    Standard imaging of pancreas is generally obtained by computed tomography and magnetic resonance imaging. However endoscopic ultrasound (EUS) has become an indispensable tool for the diagnosis of various pancreatic diseases. Because of the close proximity of the EUS probe to the pancreas, EUS provides excellent images of the pancreas. In this review, we discuss the role of EUS in the clinical management of patients with benign pancreatic diseases, i.e., various forms of pancreatitis.

    2014-01-01

    Full Text Available Background: The aim of this study was to report our results on premenarchal girls with adnexal torsion who were treated with different approaches. Materials and Methods: Twenty-six adnexal torsions in children were analysed retrospectively. Group 1 included cases of oophorectomy for the twisted adnexa. Group 2 contained the patients with adnexal torsion who untwisted either with a laparoscopic or open approach. Postoperative restoration of ovarian function was evaluated by Doppler ultrasound at the 6 th month. All oophorectomy and biopsy specimens were also evaluated. Results: Group 1 consisted of eleven cases that underwent oophorectomy due to gangrenous change and haemorrhagic infarction. Histology was of a mature teratoma in two cases and haemorrhagic necrosis due to torsion in seven. Group 2 consisted of 15 patients. In 10 out of 15 patients, preoperative biopsy is performed in which their histology revealed haemorrhagic necrosis in eight cases, and simple cyst with a benign nature in two cases. In all of the 10 untwisted adnexas, postoperative radiological imaging showed complete recovery with normal follicular development. No malignancy or increased tumour markers were noted in both groups. Conclusion: Adnexas can be left in place regardless of the preoperative degree of necrosis. Biopsy can be added to the procedure to rule out malignancy.

    Full Text Available Anti-tumor properties assigned to PEDF, beside its role as an inhibitor of angiogenesis, make it a promising candidate in the search of new biomarkers for malignancy. In this study levels of PEDF were investigated in pleural effusions from lung adenocarcinoma and benign inflammatory disease patients. The mean PEDF concentration in the malignant group was slightly superior to that in patients suffering benign diseases (4.59 μg/mL vs 3.97 μg/mL, although the difference did not reach statistical significance (P 0.166. Pleural effusion PEDF levels were not related to gender, age, smoking habit or pleural effusion size. We also investigated the possible relationship of PEDF levels in pleural effusion regarding clinicopathological features. Correlations were found for monocytes (P 0.010 and polymorphonuclear leukocytes (P 0.023 with PEDF levels in pleural effusion of malignant origin.

    Elevation in the total sialic acid (TSA), TSA/total protein (TSA/TP) and lipid-bound sialic acid (LASA) concentration in serum occurs in breast cancer and we have studied the applicability of the assays in classification of undefined breast tumors. Sialic acid was determined by HPLC and the statistical evaluation included the receiver operating characteristic (ROC) and Youden's index analyses. In cancer patients, the serum LASA and TSA concentration was significantly higher (p breast cancer and benign breast disease and at the specificity level of 0.95 the corresponding sensitivities were 0.32 (TSA), 0.14 (TSA/TP) and 0.23 (LASA). The results indicate that both breast cancer and benign breast disease cause elevation of TSA, TSA/TP and LASA values in serum and do not provide reliable classification of undefined breast tumors.

    We evaluated the characteristics of the benign and malignant nodules on transrectal ultrasound in diagnosis of prostatic disease. Histologic examination of the trans perineal prostatic biopsy of the total 47 cases resulted in 19 cases of BPH, 8 cases of prostatic cancer, and 20 cases of normal prostatic tissue group. The hypoechoic mass in peripheral zone on TRUS had high possibility of prostatic carcinoma and the isoechoic or mixed echogenic mass in central gland had high possibility of benign lesion. Hypoechoic haloes around nodules and cysts were noted in BPH and normal prostatic tissue group, that were compatible with benign lesion. The mean value of PSA was 12.0 ng/ ml in BPH, 8.5 ng / ml in normal prostatic tissue group, and 65.6 ng / ml in prostatic cancer, which was very high in prostatic cancer. Between BPH and normal prostatic tissue group, there was no demonstrable difference in location of nodule, pattern of calcification, and echogenicity of the nodules on TRUS. The size of prostatic gland was relatively smaller and mean value of PSA was lower in normal prostatic tissue group, compared with in BPH. In conclusion, the location of the nodules and PSA value are considered to be important in differentiation of the benign and malignant prostatic nodules

    Langhe, Ream

    2015-01-28

    Ovarian cancer is the seventh most common cancer in women and the most frequent cause of gynaecological malignancy-related mortality in women. Currently, no standardized reliable screening test exists. MicroRNA profiling has allowed the identification of signatures associated with diagnosis, prognosis and response to treatment of human tumours. The aim of this study was to determine if a microRNA signature could distinguish between malignant and benign ovarian disease. A training set of 5 serous ovarian carcinomas and 5 benign serous cystadenomas were selected for the initial experiments. The validation set included 20 serous ovarian carcinomas and 20 benign serous cystadenomas. The serum\\/plasma focus microRNA Exiqon panel was used for the training set. For the validation set a pick and mix Exiqon panel, which focuses on microRNAs of interest was used. A panel of 4 microRNAs (let-7i-5p, miR-122, miR-152-5p and miR-25-3p) was significantly down regulated in cancer patients. These microRNAs target WNT signalling, AKT\\/mTOR and TLR-4\\/MyD88, which have previously been found to play a role in ovarian carcinogenesis and chemoresistance. let-7i-5p, miR-122, miR-152-5p and miR-25-3p could act as diagnostic biomarkers in ovarian cancer.

    AIM: To prospectively present our initial experience with totally laparoscopic transhiatal esophagogastrectomies for benign diseases of the cardia and distal esophagus.METHODS: Laparoscopic gastric mobilization and tubularization combined with transhiatal esophageal dissection and intrathoracic esophagogastric anastomosis accomplished by a circular stapler was done in 3 patients. There were 2 females and 1 male patient with a mean age of 73 + 5 years.RESULTS: Two patients were operated on due to benign stromal tumor of the cardia and one patient had severe oesophageal peptic stenosis. Mean blood loss was 47 ± 15 mL and mean operating time was 130 +10 min. There were no cases that required conversion to laparotomy. All patients were extubated immediately after surgery. Soft diet intake and ambulation times were 5.1 ± 0.4 d and 2.6 ± 0.6 d, respectively. There were no intraoperative and postoperative complications and there were no perioperative deaths. The average length of hospital stay was 9.3 + 3 d. All procedures were curative and all resected margins were tumor free. The mean number of retrieved lymph nodes was 18 ± 8.CONCLUSION: Laparoscopic transhiatal esophagogastrectomy for benign lesions has good effects and proves feasible and safe.

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

    PurposeThere have been few case reports describing cystic duct stent insertion in the management of acute cholecystitis secondary to benign disease with no case series published to date. We present our series demonstrating the role of cystic duct stents in managing benign gallbladder disease in those patients unfit for surgery.Materials and MethodsThirty three patients unfit for surgery in our institution underwent cystic duct stent insertion for the management of acute cholecystitis in the period June 2008 to June 2013. Patients underwent a mixture of transperitoneal and transhepatic gallbladder puncture. The cystic duct was cannulated with a hydrophilic guidewire which was subsequently passed through the common bile duct and into the duodenum. An 8Fr 12-cm double-pigtail stent was placed with the distal end lying within the duodenum and the proximal end within the gallbladder.ResultsTen patients presented with gallbladder perforation, 21 patients with acute cholecystitis, 1 with acute cholangitis and 1 with necrotising pancreatitis. The technical success rate was 91 %. We experienced a 13 % complication rate with 3 % mortality rate at 30 days.ConclusionCystic duct stent insertion can be successfully used to manage acute cholecystitis, gallbladder empyema or gallbladder perforations in those unfit for surgery and should be considered alongside external gallbladder drainage as a definitive mid-term treatment option.

  14. Impact of preventive therapy on the risk of breast cancer among women with benign breast disease.

    There are three main ways in which women can be identified as being at high risk of breast cancer i) family history of breast and/or ovarian cancer, which includes genetic factors ii) mammographically identified high breast density, and iii) certain types of benign breast disease. The last category is the least common, but in some ways the easiest one for which treatment can be offered, because these women have already entered into the treatment system. The highest risk is seen in women with lobular carcinoma in situ (LCIS), but this is very rare. More common is atypical hyperplasia (AH), which carries a 4-5-fold risk of breast cancer as compared to general population. Even more common is hyperplasia of the usual type and carries a roughly two-fold increased risk. Women with aspirated cysts are also at increased risk of subsequent breast cancer. Tamoxifen has been shown to be particularly effective in preventing subsequent breast cancer in women with AH, with a more than 70% reduction in the P1 trial and a 60% reduction in IBIS-I. The aromatase inhibitors (AIs) also are highly effective for AH and LCIS. There are no published data on the effectiveness of tamoxifen or the AIs for breast cancer prevention in women with hyperplasia of the usual type, or for women with aspirated cysts. Improving diagnostic consistency, breast cancer risk prediction and education of physicians and patients regarding therapeutic prevention in women with benign breast disease may strengthen breast cancer prevention efforts.

    Ocular adnexal amyloidosis is characterized by amyloid deposition within the deep connective tissue layers of the eyelids, conjunctiva, and anterior orbit. Management of advanced cases has traditionally been unsatisfactory, with either no surgery offered because of fear of hemorrhage or an en bloc resection performed of the entire involved area. We present two cases of advanced periorbital amyloidosis successfully managed by preserving the anatomic planes of the eyelids and meticulously debulking the deposits with a spooned curette. Lax eyelid tendons and aponeuroses were simultaneously repaired, and no sacrifice of eyelid tissues was necessary. One patient remained asymptomatic for 2 years after surgery before developing early reaccumulation in the lower eyelids. The other patient required additional eyelid debulking and ptosis revision 8 months after surgery, but was in stable condition at follow-up 2 years after surgery. This technique offers safe, easily repeatable, nondestructive treatment for advanced periocular amyloidosis.

    A comprehensive comparison of couples' adjustment to benign (n = 73 couples) and malignant breast disease (n = 58 couples) at the time of diagnosis and at two follow-up assessments at 60 days and 1 year is reported. Specific objectives were to: (a) compare the concurrent stress, resources, appraisal, and patterns of adjustment of couples in the benign and malignant groups; (b) compare the psychosocial responses of patients versus spouses; and (c) determine the amount of correspondence in levels of adjustment reported by patients and their husbands over time. Multiple instruments with reported reliability and validity were used to measure study variables: Smilkstein Stress Scale, Dyadic Adjustment Scale, Family APGAR, Social Support Questionnaire, Mishel Uncertainty in Illness Scale, Beck Hopelessness Scale, Brief Symptom Inventory, and Psychosocial Adjustment to Illness Scale. Mixed design analyses of covariance (ANCOVA) were used to assess differences between and among couples and examine changes in study variables over time. Significant differences were found in the resources, appraisal, and patterns of adjustment reported by couples in the benign and malignant groups. Couples facing breast cancer reported greater decreases in their marital and family functioning, more uncertain appraisals, and more adjustment problems associated with the illness. In addition, there was a high degree of correspondence between the levels of adjustment reported by women with breast cancer and their husbands over time. Couples who reported high distress or a high number of role problems at diagnosis were likely to remain highly distressed at 60 days and 1 year. Study findings underscore the importance of assisting couples, not just patients, to manage the adjustment difficulties associated with breast cancer.

    Lymphadenopathy is a common radiological finding in many thoracic diseases and may be caused by a variety of infectious, inflammatory, and neoplastic conditions. This review aims to describe the patterns of mediastinal and hilar lymphadenopathy found in benign diseases in immunocompetent patients. Computed tomography is the method of choice for the evaluation of lymphadenopathy, as it is able to demonstrate increased size of individual nodes, abnormalities of the interface between the mediastinum and lung, invasion of surrounding fat, coalescence of adjacent nodes, obliteration of the mediastinal fat, and hypo- and hyperdensity in lymph nodes. Intravenous contrast enhancement may be needed to help distinguish nodes from vessels. The most frequent infections resulting in this finding are tuberculosis and fungal disease (particularly histoplasmosis and coccidioidomycosis). Sarcoidosis is a relatively frequent cause of lymphadenopathy in young adults, and can be distinguished from other diseases - especially when enlarged lymph nodes are found to be multiple and symmetrical. Other conditions discussed in this review are silicosis, drug reactions, amyloidosis, heart failure, Castleman's disease, viral infections, and chronic obstructive pulmonary disease.

  20. Topical PDT in the Treatment of Benign Skin Diseases: Principles and New Applications

    Directory of Open Access Journals (Sweden)

    2015-09-01

    Full Text Available Photodynamic therapy (PDT uses a photosensitizer, light energy, and molecular oxygen to cause cell damage. Cells exposed to the photosensitizer are susceptible to destruction upon light absorption because excitation of the photosensitizing agents leads to the production of reactive oxygen species and, subsequently, direct cytotoxicity. Using the intrinsic cellular heme biosynthetic pathway, topical PDT selectively targets abnormal cells, while preserving normal surrounding tissues. This selective cytotoxic effect is the basis for the use of PDT in antitumor treatment. Clinically, PDT is a widely used therapeutic regimen for oncologic skin conditions such as actinic keratosis, squamous cell carcinoma in situ, and basal cell carcinoma. PDT has been shown, under certain circumstances, to stimulate the immune system and produce antibacterial, and/or regenerative effects while protecting cell viability. Thus, it may be useful for treating benign skin conditions. An increasing number of studies support the idea that PDT may be effective for treating acne vulgaris and several other inflammatory/infective skin diseases, including psoriasis, rosacea, viral warts, and aging-related changes. This review provides an overview of the clinical investigations of PDT and discusses each of the essential aspects of the sequence: its mechanism of action, common photosensitizers, light sources, and clinical applications in dermatology. Of the numerous clinical trials of PDT in dermatology, this review focuses on those studies that have reported remarkable therapeutic benefits following topical PDT for benign skin conditions such as acne vulgaris, viral warts, and photorejuvenation without causing severe side effects.

    The aim was to determine the efficacy, safety, and long-term clinical and functional results of coloanal anastomosis in patients with complicated benign and malignant rectal disease. Twenty-nine patients underwent coloanal or colopouch-anal anastomosis for either carcinoma of the rectum not technically amenable to conventional low anterior resection, severe radiation injury, large benign lower third tumors, or complications of previous operations. The mean age of the patients was 61 years and 82% were men. A diverting colostomy was constructed in 55% of the patients. The mean (+/- SEM) length of follow-up was 20 +/- 3 months. There was no operative mortality. Transient urinary retention, however, occurred in 40%, anastomotic stricture in 28%, and anastomotic leakage in 3.4%. Four patients (14%) could not have intestinal continuity restored and therefore were considered failures. The stool frequency for all remaining patients (N = 25) was 3 +/- 1 per day (mean +/- SEM) and did not vary with age, sex, or indication for operation. Complete continence was achieved by 84% of patients, but no patient was incapacitated by poor bowel function. In patients in whom a conventional colorectostomy is impractical or unwise, coloanal anastomosis is a safe and efficacious alternative operation that preserves anal continence.

    Full Text Available OBJECTIVE: Analyze the success rate, complications and overall benefit of ultrasound guided percutaneous nephrostomy (PCN for the relief of obstructive uropathy in benign and malignant diseases. MATERIALS AND METHODS: PCN was performed in 50 kidneys of 32 patients. It was performed in emergency rooms totally under ultrasound guidance by general surgeons. Seldinger technique was used in all cases. Changes in renal function after the procedure were analyzed using paired t-test. RESULTS: The procedure was successfully completed in 42 out of 50 kidneys (84%. There has been no major complication and 28% minor complications. The renal function improved significantly when PCN was performed for benign conditions (mean creatinine 3.52 mg/dL before and 2.18 mg/dL after PCN, however in malignancy there has been no significant improvement in renal function (before PCN mean creatinine 6.39 mg/dL and after PCN 5.41 mg/dL. CONCLUSION: We conclude that PCN can be effectively performed under ultrasound guidance and should be the initial procedure in acutely obstructed kidneys with pyonephrosis and poor renal function. In malignant cases, however, improvement in renal function is possible only if the procedure is carried out at an early stage.

    Full Text Available La exposición al asbesto es una causa importante de patología pleural y se puede producir con intensidades moderadas o ligeras dada la capacidad del asbesto de concentrarse en la pleura. Ello motiva junto a la prolongada latencia existente entre la exposición y la enfermedad, que sigamos viendo durante muchos años manifestaciones clínicas pleurales de exposición previa, a pesar del uso del asbesto cada vez más limitado en las últimas décadas. Dicha exposición puede presentarse con distintas manifestaciones tanto malignas como el mesotelioma como benignas, siendo las principales de éstas el derrame pleural benigno, las placas pleurales, la fibrosis pleural difusa y la atelectasia redonda.Exposure to asbestos is an important cause of pleural pathology and can be produced with light or moderate tendencies given the capacity of asbestos to concentrate in the pleura. Together with the prolonged latency existing between exposure and the disease, this means that for many years we will continue to see pleural clinical manifestations from past exposure, in spite of the increasingly limited use of asbestos in recent decades. This exposure can show itself in different manifestations, both malign, such as mesothelioma, and benign, principally benign pleural effusion, pleural plaques, diffuse pleural fibrosis and massive atelectasis.

    To evaluate the tomographic features in differentiating benign from malignant splenic diseases, 54 patients with a cytohistological examination and a contrast-enhanced multidetector computed tomography (ce-MDCT) and/or positron emission tomography/computed tomography (PET/CT) were retrospectively selected. Significant associations were observed between ce-MDCT Pattern 3 (focal hyperdense lesion) and Pattern 4 (infarcts/cysts) as well as PET/CT Pattern 3 (focal photopenia/diffuse uptakebenign pathologies, and between ce-MDCT Pattern 1 (splenomegaly without focal lesions) and Pattern 2 (focal hypodense lesion) as well as PET/CT Pattern 1 (diffuse uptake ≥ liver) and Pattern 2 (focal increased uptake) and malignant diseases. No significant association between benign or malignant diseases and spleen volumes and maximum standardized uptake value (SUV(max)) as well as lesion characteristics was observed. The metabolic data do not improve the performance of morphological patterns.

    One or more abnormal vertebrae detected on bone scintigraphy is a common finding in clinical practice, and it could pose a diagnostic dilemma especially in cancer patients, as either metastasis or benign disease may cause scintigraphic abnormality. The purpose of this study was to determine whether additional spine SPECT has a role in differentiating malignant from benign lesions in patients with back pain. We reviewed spine SPECT studies obtained over a three-year period in 108 patients. Among them, forty-five patients with abnormal SPECT and clinically followed records were evaluated (20 cancer patients were included). Uptake patterns were classified as follows: 1. Body: diffusely increased uptake, linear increased uptake of end plate, segmental increased uptake, and cold defect, 2 Posterior element; posterior to body (pedicle), posterior to intervertebral disc space (facet joint), and spinous process. Lesions were correlated with radiological findings and with final diagnosis. Sixty-nine bone lesions were detected on SPECT images, including 18 metastases, 28 degenerative diseases and 21 compression fractures. Cold defect (6) and segmental increased uptake (5) were dominant findings in metastasis: linear increased uptake (12), and facet joint uptake (15) were in degenerative change; and diffuse increased uptake (9), and linear increased uptake (9) were in compression fracture. Cold defect and segmental increased uptake of body were characteristic findings of metastasis, but care should be taken because compression fracture also shows segmental increased uptake in some cases. Degenerative disease was easily diagnosed because of the typical finding of linear increased uptake of end plate and facet joint. Therefore, additional bone SPECT after planar bone scan would be helpful for differentiating metastasis from benign condition in cancer patients.

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

    Full Text Available Objective. To report our experience treating adnexal masses using a combination of the SILS port and straight nonroticulating laparoscopic instruments. Study Design. This prospective feasibility study included 14 women with symptomatic and persistent adnexal masses. Removal of adnexal masses via single-incision laparoscopic surgery using a combination of the SILS port and straight nonroticulating laparoscopic instruments was performed. Results. All of the patients had symptomatic complex adnexal masses. Mean age of the patients was 38.4 years (range: 21–61 years and mean duration of surgery was 71 min (range: 45–130 min. All surgeries were performed using nonroticulating straight laparoscopic instruments. Mean tumor diameter was 6 cm (range: 5–12 cm. All patient pathology reports were benign. None of the patients converted to laparotomy. All the patients were discharged on postoperative d1. Postoperatively, all the patients were satisfied with their incision and cosmetic results. Conclusion. All 14 patients were successfully treated using standard, straight nonroticulating laparoscopic instruments via the SILS port. This procedure can reduce the cost of treatment, which may eventually lead to more widespread use of the SILS port approach. Furthermore, concomitant surgical procedures are possible using this approach. However, properly designed comparative studies with single port and classic laparoscopic surgery are urgently needed.

    Full Text Available Objective. Currently, total thyroidectomy (TT is widely used to treat benign thyroid diseases and thyroid carcinoma. The differential diagnosis between benign and malignant thyroid disorders and the potential identification of thyroid microcarcinomas with biochemical markers remain controversial. This retrospective study aimed to estimate the prognostic validity of thyroid autoantibodies, thyroglobulin (Tg, and the thyroid disease type in diagnostic approaches regarding the co-existence of incidental thyroid carcinoma (ITC with benign thyroid diseases. Methods. A cohort of 228 patients was treated with TT for benign thyroid disorders between 2005 and 2010. Thyroid autoantibodies and Tg were preoperatively estimated. Patients were classified according to the preoperative and histologically established diagnoses, and the median values of the biochemical markers were compared between the groups. Results. ITC was detected in 33/228 patients and almost exclusively in the presence of nontoxic thyroid disorders (. There were no statistically significant differences in the median values of the biochemical markers between the benign and malignant groups. There was also no significant association between ITC and chronic lymphocytic thyroiditis. Conclusions. The co-existence of ITC with benign and especially nontoxic thyroid diseases is significant, and treatment of these disorders with TT when indicated can lead to the identification and definitive cure of microcarcinomas. Further studies are required to establish precise markers with prognostic validity for TC diagnosis.

    Full Text Available Epithelial ovarian cancer (EOC is the sixth most common cause of cancer deaths in women because the diagnosis occurs mostly when the disease is in its late-stage. Current diagnostic methods of EOC show only a moderate sensitivity, especially at an early-stage of the disease; hence, novel biomarkers are needed to improve the diagnosis. We recently reported that serum glycome modifications observed in late-stage EOC patients by MALDI-TOF-MS could be combined as a glycan score named GLYCOV that was calculated from the relative areas of the 11 N-glycan structures that were significantly modulated. Here, we evaluated the ability of GLYCOV to recognize early-stage EOC in a cohort of 73 individuals comprised of 20 early-stage primary serous EOC, 20 benign ovarian diseases (BOD, and 33 age-matched healthy controls. GLYCOV was able to recognize stage I EOC whereas CA125 values were statistically significant only for stage II EOC patients. In addition, GLYCOV was more sensitive and specific compared to CA125 in distinguishing early-stage EOC from BOD patients, which is of high relevance to clinicians as it is difficult for them to diagnose malignancy prior to operation.

    Glycogen storage disease type Ia (GSD-Ia; von Gierke disease) is an inherited disorder caused by glucose-6-phosphatase deficiency, and there have been some reports of hepatic tumors in patients with this disease. We report two patients with benign hepatic tumors with GSD-Ia. One is a 19-year-old man who underwent segmentectomy 4 for a focal nodular hyperplasia, and the other is a 31-year-old woman who underwent segmentectomies 3, 5, and 6 for hepatic adenomas. Two significant perioperative complications, resulting from the carbohydrate metabolic disorders, hypoglycemia and metabolic acidosis, occurred in both patients. We managed the metabolic complications successfully by administering a sufficient volume of glucose intravenously. Close perioperative monitoring of blood glucose and lactate concentrations is essential in the perioperative management of patients with GSD-Ia. The intravenous administration of glucose, starting with a smaller dose and then increasing the dose, is adequate management for lactic acidosis with or without hypoglycemia during the perioperative period.

    Caroli's disease is a rare congenital disorder characterized by cystic dilatation of the large in-trahepatic bile ducts. The most frequent complications due to biliary stasis are cholelithiasis, cholangitis and sepsis as well as an increased risk of cholangiocarcinoma. Patients may have a history of intermittent abdominal pain, pruritus and/or symptoms of cholangitis. It is rarely diagnosed in childhood. A 12-year-old boy with isolated Caroli's disease is described. This child presented at the age of 2 years, with 4 episodes of recurrent bacterial infections. Interestingly he remained asymptomatic for over 10 years, between the second and third episode. During the 4th episode, when he presented with fever and slight abdominal pain, the diagnosis was made on the basis of radiological findings: U/S, CT, MRI and especially with MRCP, in relation with a more typical picture, resembling cholangitis. Since then he has been followed-up systematically for ten years and remains in good clinical condition without further relapses and with unchanged radiological findings. This atypically benign course of Caroli's disease, with intermittent asymptomatic periods, without any treatment, is very rare.

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

  15. Benign and malignant nodular thyroid disease in acromegaly. Is a routine thyroid ultrasound evaluation advisable?

    Full Text Available Data on the prevalence of benign and malignant nodular thyroid disease in patients with acromegaly is a matter of debate. In the last decade an increasing incidence of thyroid cancer has been reported. The aim of this study was to evaluate the prevalence of goiter, thyroid nodules and thyroid cancer in a large series of patients with acromegaly with a cross-sectional study with a control group. Six Spanish university hospitals participated. One hundred and twenty three patients (50% men; mean age 59±13 years; disease duration 6.7±7.2 years and 50 controls (51% males, mean age 58±15 years were studied. All participants underwent thyroid ultrasound and fine needle aspiration. Cytological analysis was performed in suspicious nodules between 0.5 and 1.0 cm and in all nodules greater than 1.0 cm. Goiter was more frequently found in patients than in controls (24.9 vs. 8.3%, respectively; p<0.001. Nodular thyroid disease as well as nodules greater than 1 cm were also more prevalent in acromegalic patients (64.6%, vs. 28.6%, p<0.05 and 53.3 vs. 28.6%, respectively; p<0.05, and all underwent fine needle aspiration. Suspicious cytology was detected in 4 patients and in none of the controls. After thyroidectomy, papillary thyroid carcinoma was confirmed in two cases (3.3% of patients with thyroid nodules, representing 1.6% of the entire group of patients with acromegaly (2.4% including a case with previously diagnosed papillary thyroid carcinoma. These data indicated that thyroid nodular disease and cancer are increased in acromegaly, thus justifying its routine ultrasound screening.

    Full Text Available Acantholytic dyskeratosis (AD is a histologic pattern seen in Darier's disease or dyskeratosis follicularis, warty dyskeratoma, and transient AD. This pattern is characterized by suprabasilar clefting, acantholysis, and formation of corps ronds and grains. We present a case of AD that is unique based on its genital location and cystic architecture. A 53-year-old woman presented with an otherwise asymptomatic cyst on her left vulva of uncertain duration. On microscopic examination, there were fragments of cystic epithelium with areas of hypergranulosis, acantholysis, corps ronds, and corps grains formation. These features are felt by the authors to be a unique presentation of a follicular adnexal neoplasm.

    The purpose of this study is to examine the breast cancer risk overall among women with simple fibroadenoma or complex fibroadenoma and to examine the association of complex fibroadenoma with breast cancer through stratification of other breast cancer risks. The study included women aged 18-85 years from the Mayo Clinic Benign Breast Disease Cohort who underwent excisional breast biopsy from 1967 through 1991. Within this cohort, women who had fibroadenoma were compared to women who did not have fibroadenoma. Breast cancer risk (observed versus expected) across fibroadenoma levels was assessed through standardized incidence ratios (SIRs) by using age- and calendar-stratified incidence rates from the Iowa Surveillance, Epidemiology, and End Results registry. Analyses were performed overall, within subgroups of involution status, with other demographic characteristics (age, year of biopsy, indication for biopsy, and family history), and with histologic characteristics, including overall impression [nonproliferative disease, proliferative disease without atypia (PDWA), or atypical hyperplasia]. Fibroadenoma was identified in 2136 women [noncomplex, 1835 (85.9%); complex, 301 (14.1%)]. SIR for noncomplex fibroadenoma was 1.49 (95% CI 1.26-1.74); for complex fibroadenoma, it was 2.27 (95% CI 1.63-3.10) (test for heterogeneity in SIR, P = .02). However, women with complex fibroadenoma were more likely to have other, concomitant high-risk histologic characteristics (e.g., incomplete involution and PDWA). In analyses stratified by involution status and PDWA, complex fibroadenoma was not an independent risk marker for breast cancer. Complex fibroadenoma does not confer increased breast cancer risk beyond other established histologic characteristics.

    Over the last few years, incidental thyroid microcarcinoma (TMC) has become a frequent disease and its incidence in some reports is considerable. The discovery of new cases depends on the progress of the diagnostics (US scan, fine needle biopsy and cytology, CT, MRI), on the extended indications to thyroidectomy for benign disease and on the attention in pathologic examination of the specimen. The clinical evolution of this disease is not well known: in spite of a high incidence reported in some autoptic series, suggesting that this tumour could have a good prognosis, some authors report an overall incidence of up to 11% of local recurrence, metastasis and mortality. For these reasons the treatment of TMC is still controversial today. Aim of this study was to estimate the incidence and the clinico-pathological findings of TMC over a one year period of total thyroidectomies for diffuse benign thyroid diseases, and to evaluate, on the basis of the frequency of incidental microcarcinoma, if the surgical procedure of complete removal of the gland should be adopted in any case. In this series no patient had pre-operative diagnosis or tentative diagnosis of carcinoma and the incidence of TMC at the final histologic examination was 27.4%. Total thyroidectomy confirmed to be the treatment of choice for diffuse benign diseases and appeared necessary to obtain both, diagnosis and treatment of incidental TMC.

    Purpose: To assess the shape of the dose-response for various circulatory disease endpoints, and modifiers by age and time since exposure. Methods and Materials: This was an analysis of the US peptic ulcer data testing for heterogeneity of radiogenic risk by circulatory disease endpoint (ischemic heart, cerebrovascular, other circulatory disease). Results: There were significant excess risks for all circulatory disease, with an excess relative risk Gy{sup -1} of 0.082 (95% CI 0.031-0.140), and ischemic heart disease, with an excess relative risk Gy{sup -1} of 0.102 (95% CI 0.039-0.174) (both p = 0.01), and indications of excess risk for stroke. There were no statistically significant (p > 0.2) differences between risks by endpoint, and few indications of curvature in the dose-response. There were significant (p < 0.001) modifications of relative risk by time since exposure, the magnitude of which did not vary between endpoints (p > 0.2). Risk modifications were similar if analysis was restricted to patients receiving radiation, although the relative risks were slightly larger and the risk of stroke failed to be significant. The slopes of the dose-response were generally consistent with those observed in the Japanese atomic bomb survivors and in occupationally and medically exposed groups. Conclusions: There were excess risks for a variety of circulatory diseases in this dataset, with significant modification of risk by time since exposure. The consistency of the dose-response slopes with those observed in radiotherapeutically treated groups at much higher dose, as well as in lower dose-exposed cohorts such as the Japanese atomic bomb survivors and nuclear workers, implies that there may be little sparing effect of fractionation of dose or low-dose-rate exposure.

    Version 4 of the guideline for radioiodine therapy for benign thyroid diseases includes an interdisciplinary consensus ondecision making for antithyroid drugs, surgical treatment and radioiodine therapy. The quantitative description of a specific goiter volume for radioiodine therapy or operation was cancelled. For patients with nodular goiter with or without autonomy, manifold circumstances are in favor of surgery (suspicion on malignancy, large cystic nodules, mediastinal goiter, severe compression of the trachea) or in favor of radioiodine therapy (treatment of autonomy, age of patient, co-morbidity, history of prior subtotal thyroidectomy, profession like teacher, speaker or singer). For patients with Graves' disease, radioiodine therapy or surgery are recommended in the constellation of high risk of relapse (first-line therapy), persistence of hyperthyroidism or relapse of hyperthyroidism. After counseling, the patient gives informed consent to the preferred therapy. The period after radioiodine therapy of benign disorders until conception of at least four months was adapted to the European recommendation. (orig.)

    Being recalled for further diagnostic procedures after an abnormal screening mammogram (ASM) can evoke a high state anxiety with lowered quality of life (QoL). We examined whether these adverse psychological consequences are found in all women with benign breast disease (BBD) or are particular to women referred after ASM. In addition, the influence of the anxiety as a personality characteristic (trait anxiety) was studied. Between September 2002 and February 2010 we performed a prospective longitudinal study in six Dutch hospitals. Women referred after ASM or with a palpable lump in the breast (PL), who were subsequently diagnosed with BBD, were included. Before diagnosis (at referral) and during follow-up, questionnaires were completed examining trait anxiety (at referral), state anxiety, depressive symptoms (at referral, one, three and 6 months after diagnosis), and QoL (at referral and 12 months). Women referred after ASM (N=363) were compared with women with PL (N=401). A similar state anxiety score was found in both groups, but a lower psychological QoL score at 12 months was seen in the ASM group. In women with not-high trait anxiety those in the ASM group were more anxious with more depressive symptoms at referral, and reported impaired psychological QoL at referral and at 12 months compared with the PL group. No differences were found between ASM and PL in women with high trait anxiety, but this group scored unfavorably on anxiety, depressive symptoms and QoL compared with women with not-high trait anxiety. ASM evokes more anxiety and depressive symptoms and lowered QoL compared with women referred with PL, especially in women who are not prone to anxiety. Women should be fully informed properly about the risks and benefits of breast cancer screening programs. We recommend identifying women at risk of reduced QoL using a psychometric test.

    The intention of the present thesis was the evaluation of a potential parathyroid dysfunction under treatment with radioactive iodine of benign thyroid diseases. It was to be examined whether a change in the parathyroid function would arise within the first week on treatment. So far there are some minor studies existing describing significant changes in the parathyroid hormone serum level within the first months after radioactive iodine therapy of benign and malignant thyroid diseases. Moreover, it is a fact that external beam-radiotherapy can induce neoplasia and that the risk for the subsequent development of primary hyperparathyroidism doubles or triples after external beam-radiotherapy of the head and neck. Up to now, however, an increased incidence for primary hyperparathyroidism following treatment with radioactive iodine ({sup 131}I) could not be proved. At the department of nuclear medicine of the university hospital Giessen-Marburg GmbH, location Marburg, a prospective cohort study was executed on radioactive iodine therapy of benign thyroid diseases with 105 probands (75 women / 30 men, mean age 60.62 ± 14.3 years). According to their thyroid diseases these 105 probands were classified into following subgroups: thyroid adenoma with 23 patients, multifocal thyroid autonomy with 8 patients, disseminated thyroid autonomy with 37 patients as well as the subgroup Graves' hyperthyroidism (without Graves' ophtalmopathy) and accordingly Graves' disease (with Graves' ophtalmopathy) with 37 patients. The serum level of the intact parathyroid hormone was determined directly before starting the radioactive iodine therapy on the admission day and on day 1, 3 and 5 of the radioactive iodine therapy as well as at the ambulant follow-up examination one month after the start of the therapy. In case of 99 of 105 probands the serum level of parathyroid hormone declined on treatment with {sup 131}I with its nadir on day 3 of therapy (decline by 15.71 ng

    Benign breast disease increases the risk of breast cancer. This association has scarcely been evaluated in the context of breast cancer screening programs although it is a prevalent finding in mammography screening. We assessed the association of distinct categories of benign breast disease and subsequent risk of breast cancer, as well as the influence of a family history of breast cancer. A retrospective cohort study was conducted in 545,171 women aged 50-69 years biennially screened for breast cancer in Spain. The median of follow-up was 6.1 years. The age-adjusted rate ratio (RR) of breast cancer for women with benign breast disease, histologically classified into nonproliferative and proliferative disease with and without atypia, compared with women without benign breast disease was estimated by Poisson regression analysis. A stratified analysis by family history of breast cancer was performed in a subsample. All tests were two-sided. The age-adjusted RR of breast cancer after diagnosis of benign breast disease was 2.51 (95 % CI: 2.14-2.93) compared with women without benign breast disease. The risk was higher in women with proliferative disease with atypia (RR = 4.56, 95 % CI: 2.06-10.07) followed by those with proliferative disease without atypia (RR = 3.58; 95 % CI = 2.61-4.91). Women with nonproliferative disease and without a family history of breast cancer remained also at increased risk of cancer (OR = 2.23, 95 % CI: 1.86-2.68). An increased risk of breast cancer was observed among screening participants with proliferative or nonproliferative benign breast disease, regardless of a family history of breast cancer. This information may be useful to explore risk-based screening strategies.

    2013-01-01

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

    concentrations cannot exclude the respective disorder, a routine Tg determination seems not to be justified in benign thyroid diseases. (orig.) [German] Ziel dieser Studie ist es, neue und bislang zum Teil kontrovers diskutierte Indikationen zur Bestimmung des Thyreoglobulins (Tg) bei unterschiedlichen Schilddruesenerkrankungen in der klinischen Routine zu ueberpruefen. Methoden: Die Studie umfasst folgende Kollektive: 250 gesunde Probanden, 50 Patienten mit euthyreoter Struma diffusa, 161 Patienten mit euthyreoter Knotenstruma (davon 108 operierte Faelle, wobei sich 17 Karzinome fanden), 60 hyperthyreote Patienten mit autonomer Knotenstruma, 150 Patienten mit Thyreoiditis Hashimoto und 30 hyperthyreote Patienten mit M. Basedow. Ergebnisse: Die Grenze des Referenzbereichs errechnete sich zu 30 ng Tg/ml. Die Analyse der diffusen Strumen zeigte eine lineare Abhaengigkeit des Tg-Spiegels von der Schilddruesengroesse, wobei der Erwartungswert in etwa dem Organvolumen in ml entsprach. Knotige Veraenderungen fuehrten zu einem ueberproportionalen Tg-Anstieg, der allerdings einer grossen Varianz unterlag und daher im Einzelfall nur schwer abzuschaetzen war. Von den 17 Patienten mit Schilddruesenkarzinom lag der Tg-Spiegel in 10 Faellen unterhalb des Erwartungswertes, 2 Patienten zeigten einen Tg-Wert von >1000 ng/ml. Bei Autonomien fand sich bezogen auf eine durch Substitution extrem supprimierte Vergleichsgruppe ein signifikant hoeherer mittlerer Tg-Spiegel. Aufgrund der hohen Varianz der Tg-Werte beider Kollektive war die Diagnose der Autonomie anhand der Tg-Bestimmung jedoch kaum moeglich. In der Gruppe mit Thyreoiditis Hashimoto zeigte sich im Vergleich zum Normalkollektiv ein erniedrigter Tg-Spiegel. Bei M. Basedow war die mittlere Tg-Konzentration signifikant hoeher als in der Vergleichsgruppe mit Struma diffusa, dennoch lagen 47% aller Werte noch im Referenzbereich. Schlussfolgerung: Hohe Tg-Werte fuehren bei Verdacht auf Malignitaet, Autonomie oder M. Basedow zu einer hoeheren

    To evaluate the increased value of using coronal reformation of a transverse computed tomography (CT) scan for detecting adnexal torsion. This study included 106 woman suspected of having adnexal torsion who underwent CT with coronal reformations and subsequent surgical exploration. Two readers independently recorded the CT findings, such as the thickening of a fallopian tube, twisting of the adnexal pedicle, eccentric smooth wall thickening of the torsed adnexal mass, eccentric septal thickening of the torsed adnexal mass, eccentric poor enhancement of the torsed adnexal mass, uterine deviation to the twisted side, ascites or infiltration of pelvic fat, and the overall impression of adnexal torsion with a transverse scan alone or combined with coronal reformation and a transverse scan. The areas under the receiver operating characteristic curves (AUCs), sensitivity, specificity, and positive predictive value were used to compare diagnostic performance. Fifty-two patients were confirmed to have adnexal torsion. The addition of coronal reformations to the transverse scan improved AUCs for readers 1 and 2 from 0.74 and 0.75 to 0.92 and 0.87, respectively, for detecting adnexal torsion (p < 0.001 and p = 0.004, respectively). Sensitivity of CT for detecting twisting of the adnexal pedicle increased significantly for readers 1 and 2 from 0.27 and 0.29 with a transverse scan alone to 0.79 and 0.77 with a combined coronal reformation and a transverse scan, respectively (p < 0.001 and p < 0.001, respectively). Use of a coronal reformation with transverse CT images improves detection of adnexal torsion.

    Extensive pelvic adhesions present difficulty with access to the uterus, but they may not account for significant symtomatology, although their dissection may account for a significant deal of morbidity. Results of this study are based on a retrospective analysis of operations by a single surgical team. Eight patients with benign uterine pathology and frozen pelvis diagnosed laparoscopically underwent vaginal hysterectomy. The surgeries were accomplished uneventfully and without significant perioperative morbidity. This approach appears to be an efficient surgical option for hysterectomy, which by-passes the need for and the potential morbidity of an extensive intra-abdominal adhesiolysis by laparotomy or laparoscopy.

    External fractionated radiotherapy of cancer increases the risk of cardio- and cerebrovascular events, but less attention has been paid to the potential side effects on the arteries following internal radiotherapy with radioactive iodine (RAI), i.e. 131-iodine. About 279 per million citizens...... in the western countries are treated each year with RAI for benign thyroid disorders (about 140,000 a year in the EU), stressing that it is of clinical importance to be aware of even rare radiation-induced side effects. In order to induce or accelerate atherosclerosis, the dose to the carotid arteries has...

    The use of somatostatin (SS) analogues in humans takes advantage by the availability of many related chemical forms that can be used for receptor therapy and, after radiolabelling, for diagnostic imaging and radionuclide therapy. The first proposed radiocompound, yet clinically widely diffuse, has been (111)In-octreotide (OCT), followed by positron emission tomography (PET) and beta emitter tracers. The main field of clinical applications is in neuroendocrine tumours (NET), starting by the demonstration of SS receptors (SSR) on the majority of NET, particularly on gastroenteropancreatic (GEP) tumours. Uptake of SS analogues can also be due to a SSR expression on non malignant cells when activated, as lymphocytes, macrophages, fibroblasts , vascular cells. Because of this uptake clinical indications can be found also in active benign diseases, as Grave's ophthalmopathy, rheumatoid arthritis, histiocitosis, sarcoidosis, idiopatic pulmonary fibrosis. Moreover, these cells can also determine the OCT in vivo uptake in tumours non expressing in vitro SSR, as non-snall cell lung cancer (NSCLC). Because of a different kinetic respect to SCLC a differential histotype diagnosis could be obtained. Starting from this premise OCT can also allows radioguided surgery in tumours non expressing SSR. Finally a relevant clinical role can be defined in the a priori recruitment and as marker of therapeutic efficacy in all the therapeutic strategies utilizing SSR, both in malignant and benign diseases.

    2016-03-01

    Full Text Available Adnexal torsion is an infrequent but significant cause of acute lower abdominal pain in women. While adnexal torsion is generally considered in premenopausal women presenting with acute abdominal pain and a pelvic mass, it is a rare cause of acute abdominal pain during postmenopausal period. The diagnosis of adnexal torsion is often challenging due to nonspesific clinical, laboratory and physical examination findings. Causes of adnexal torsion is also different in premenopausal and postmenopausal women. While a simple functional cyst is often the cause of torsion in premenopausal women, it is more rarely the cause in postmenopausal women. Adnexal torsion is a surgical emergency. The surgery of adnexal torsion is performed either via conventional exploratory laparotomy or laparoscopic surgery. Adnexal torsion in postmenopausal women should be considered not only in the setting of sudden onset pain, but also in long-term abdominal discomfort. In this article, we presented a case with adnexal torsion that rarely cause acute abdominal pain in postmenopausal women. [Cukurova Med J 2016; 41(1.000: 167-170

    Many studies have investigated the relationship between serum zinc concentration and prostatic disease, but have shown inconsistent results. Hence, we performed a systematic literature review and meta-analysis to assess the correlation between serum zinc concentration and prostate disease. Systematic literature searches were conducted with PubMed, EMBASE, Science Direct/Elsevier, MEDLINE, CNKI and the Cochrane Library up to June 2015 for studies that involved the relationship between serum zinc concentration and prostate disease. Fourteen studies were identified from the databases. Our results illustrated that the serum zinc concentrations in prostate cancer patients were significantly lower than those in Benign prostatic hyperplasia (BPH) patients and normal controls (SMD (95% CI), -0.94 [-1.57, -0.32]; -1.18 [-1.90, -0.45]). However, the serum zinc concentrations in BPH patients were significantly higher than those in normal controls (SMD (95% CI) 1.77 [0.15, 3.39]). The present study showed that different levels of serum zinc concentrations are correlated with different prostatic disease. Serum zinc concentration may be used as a tool for the diagnosis and screening of prostate disease. But, further studies with well-designed larger sample studies are needed in this field to further clarify the correlation between serum zinc concentration and prostate disease.

  18. Exosomal lncRNAs may to Help Distinguish Prostate Cancer from Benign Disease

    Full Text Available Exosomes are membranous vesicles containing various biomolecules including lncRNAs which are involved in cellular communication and are secreted from many cells including cancer cells. In our study, investigated the exosomal GAS5 and lincRNA-p21 lncRNA levels in urine samples from 30 patients with prostate cancer (PCa and 49 patients with benign prostatic hyperplasia. Quantification of lncRNA molecules was performed by real-time PCR. We observed a significant difference in the exosomal lincRNA-p21 levels between PCa and BPH patients whereas the GAS5 levels did not reveal a difference. Our data suggest that the discriminative potential of exosomal lincRNA-p21 levels may help to improve the diagnostic prediction of the malignant state for patients with prostate cancer.

    Full Text Available Abstract Background We previously showed that tumor-free peritoneum of patients with epithelial ovarian cancer (EOC exhibited enhanced expression of several inflammatory response genes compared to peritoneum of benign disease. Here, we examined peritoneal inflammatory cell patterns to determine their concordance with selected enhanced genes. Methods Expression patterns of selected inflammatory genes were mined from our previously published data base. Bilateral pelvic peritoneal and subjacent stromal specimens were obtained from 20 women with EOC and 7 women with benign pelvic conditions. Sections were first stained by indirect immunoperoxidase and numbers of monocytes/macrophages (MO/MA, T cells, B cells, and NK cells counted. Proportions of CD68+ cells and CD3+ cells that coexpressed MO/MA differentiation factors (CD163, CCR1, CXCR8, VCAM1, and phosphorylated cytosolic phospholipase A2 [pcPLA2], which had demonstrated expression in EOC peritoneal samples, were determined by multicolor immunofluorescence. Results MO/MA were present on both sides of the pelvic peritoneum in EOC patients, with infiltration of the subjacent stroma and mesothelium. CD68+ MO/MA, the most commonly represented population, and CD3+ T cells were present more often in EOC than in benign pelvic tumors. NK cells, B cells, and granulocytes were rare. CXCL8 (IL-8 and the chemokine receptor CCR1 were coexpressed more frequently on MO/MA than on CD3+ cells contrasting with CD68+/CD163+ cells that coexpressed CXCL8 less often. An important activated enzyme in the eicosanoid pathway, pcPLA2, was highly expressed on both CD68+ and CD163+ cells. The adherence molecule Vascular Cell Adhesion Molecule-1 (VCAM1 was expressed on CD31+ endothelial cells and on a proportion of CD68+ MO/MA but rarely on CD3+ cells. Conclusion The pelvic peritoneum in EOC exhibits a general pattern of chronic inflammation, represented primarily by differentiated MO/MA, and distinct from that in benign

    Sickle cell disease (SCD) in Saudi patients from the Eastern Province is associated with the Arab-Indian (AI) HBB (β-globin gene) haplotype. The phenotype of AI SCD in children was described as benign and was attributed to their high fetal haemoglobin (HbF). We conducted a hospital-based study to assess the pattern of SCD complications in adults. A total of 104 patients with average age of 27 years were enrolled. Ninety-six per cent of these patients reported history of painful crisis; 47% had at least one episode of acute chest syndrome, however, only 15% had two or more episodes; symptomatic osteonecrosis was reported in 18%; priapism in 17%; overt stroke in 6%; none had leg ulcers. The majority of patients had persistent splenomegaly and 66% had gallstones. Half of the patients co-inherited α-thalassaemia and about one-third had glucose-6-phosphate dehydrogenase deficiency. Higher HbF correlated with higher rate of splenic sequestration but not with other phenotypes. The phenotype of adult patients with AI SCD is not benign despite their relatively high HbF level. This is probably due to the continued decline in HbF level in adults and the heterocellular and variable distribution of HbF amongst F-cells.

    There is limited data on electromyography (EMG) findings in other motor neuron disorders than amyotrophic lateral sclerosis (ALS). We assessed whether the distribution of active denervation detected by EMG, i.e. fibrillations and fasciculations, differs between ALS and slowly progressive motor neuron disorders. We compared the initial EMG findings of 43 clinically confirmed, consecutive ALS patients with those of 41 genetically confirmed Late-onset Spinal Motor Neuronopathy and 14 Spinal and Bulbar Muscular Atrophy patients. Spontaneous activity was more frequently detected in the first dorsal interosseus and deltoid muscles of ALS patients than in patients with the slowly progressive motor neuron diseases. The most important observation was that absent fibrillations in the first dorsal interosseus muscle identified the benign forms with sensitivities of 66%-77% and a specificity of 93%. The distribution of active denervation may help to separate ALS from mimicking disorders at an early stage.

    Full Text Available We report a case of right adnexal torsion during pregnancy after an oocyte in vitro maturation and intracitoplasmic sperm injection cycle in patient with polycystic ovary syndrome. A 31-year-old woman with a typical clinical disorder of polycystic ovarian syndrome was included in an oocyte in vitro maturation program. Right adnexal torsion occurred two days after embryo transfer, and laparoscopy detorsion was successfully performed with preservation of adnexa. The patient had a full-term pregnancy and delivered a healthy infant at 40 weeks of gestation. To our knowledge this is the first report of adnexal torsion after an oocyte in vitro maturation and intracitoplasmic sperm injection program.

    Atypical hemolytic uremic syndrome (aHUS) is a genetic ultrarare renal disease associated with overactivation of the alternative pathway of complement. Four gain-of-function mutations that form a hyperactive or deregulated C3 convertase have been identified in Factor B (FB) ligand binding sites. Here, we studied the functional consequences of 10 FB genetic changes recently identified from different aHUS cohorts. Using several tests for alternative C3 and C5 convertase formation and regulation, we identified two gain-of-function and potentially disease-relevant mutations that formed either an overactive convertase (M433I) or a convertase resistant to decay by FH (K298Q). One mutation (R178Q) produced a partially cleaved protein with no ligand binding or functional activity. Seven genetic changes led to near-normal or only slightly reduced ligand binding and functional activity compared with the most common polymorphism at position 7, R7. Notably, none of the algorithms used to predict the disease relevance of FB mutations agreed completely with the experimental data, suggesting that in silico approaches should be undertaken with caution. These data, combined with previously published results, suggest that 9 of 15 FB genetic changes identified in patients with aHUS are unrelated to disease pathogenesis. This study highlights that functional assessment of identified nucleotide changes in FB is mandatory to confirm disease association. PMID:24652797

    Benign paroxysmal positional vertigo (BPPV) is one of the most frequently encountered primary complaints in dizziness clinics. The incidence of BPPV has been proven to increase with age. The relationship between BPPV and another neurodegenerative disease, Parkinson's disease (PD), has not been previously discussed. This study aimed to investigate the relationship of BPPV and PD with oxidative stress. A total of 30,811 subjects participated in our cohort study. The study cohort comprised 5057 BPPV patients and a comparison cohort of 25,754 nonBPPV patients. SIRT1 axis gene expression was investigated in BPPV patient blood samples and a PD cell model of 6-hydroxydopamine (6-OHDA)-treated PC-12 cells to elucidate the potential in vitro and in vivo mechanisms of degeneration in PD and BPPV. Our data suggest that BPPV patients with histories of head injuries show a significantly higher hazard to develop subsequent PD (hazard ratio, 3.942; confidence interval, 1.523-10.205, p = 0.005). We also observed that oxidative status is increased in blood samples from patients with BPPV. Our in vitro study suggests that SIRT1 function is inhibited by oxidative stress, which thereby promotes 6-hydroxydopamine-induced cell death. We conclude that BPPV is independently associated with an increased risk of PD. This finding may be attributed to oxidative stress-mediated inhibition of SIRT1 expression levels.

    Full Text Available Introduction & Background: Benign lesions are very common in breast. The most important consideration for physicians is to differentiate benign processes from malignant ones .Hence the clinicians and radi-ologists both wish to differentiate them even before surgical procedures. The Iranian Center for Breast Cancer linked to Jahad Daneshgahi Center is a referral place for patients with breast complaints. Patients & Methods: Retrospective study of sonographic findings of 111 patients with benign patho-logic diagnosis revealed 72.1% accuracy for sonogra-phy in diagnosing benign masses. In 31 cases (27.9%, the sonographic diagnosis was incorrect. Among the different benign lesions, the most common lesions were cysts, fibradenomas, and fibrocystic changes with respective sonographic accuracy of 100%, 90%, and 62.5%. Results: It shows that sonography has a high sensitiv-ity for diagnosis of benign breast lesions and this sen-sitivity is higher in cysts and fibradenomas which are the most common benign pathologies of breast. Conclusion: As a result, in this center sonography is an imaging modality for evaluating benign breast le-sion especially in young patients with dense breasts and palpable masses. Its unique role in diagnosis of the cysts is valuable especially to avoid repeated biopsies.

    A 12.5-year-old boy with Crohn's disease with abdominal pain had a raised amylase of 1835 IU/l with normal lipase levels. Ultrasound showed no evidence of inflammation of pancreas. The amylase to creatinine clearance ratio, was 0.8% (reference interval 2%-5%; >6% consistent with acute pancreatitis; amylase with a corresponding reduced clearance of amylase in his urine, positively supporting the diagnosis of macroamylasemia. Macroamylasemia has no clinical significance other than misdiagnosis as acute pancreatitis. Awareness of this condition is important and a positive diagnosis should always be made to avoid unnecessary changes in treatments.

    Preoperative diagnosis of papillary thyroid carcinoma (PTC) comprises numerous diagnostic procedures which are mostly applicable in tertiary institutions. Normal thyroid function depends on the presence of many trace elements and copper (Cu) and zinc (Zn) are some of those. The study is based on retrospective review of 118 patients with preoperatively diagnosed benign thyroid disease (BTD) and 12 with PTC, who underwent thyroid surgery at the Center for Endocrine Surgery Clinical Center of Serbia, Belgrade, between 2010 and 2012. The objective was to evaluate concentrations of Cu and Zn in serum as possible prediction markers for PTC in patients who underwent surgery for preoperatively diagnosed BTD. Concentrations of Cu and Zn ions in serum were measured using atomic absorption spectrophotometer. Data were analyzed using methods of descriptive statistics, Anova and t-test (p papillary microcarcinoma-mPTC in 13 (11.0%) of BTD patients. The concentrations of Cu ions in serum of PTC patients as well as in serum of patients with mPTC were significantly higher than in serum of BTD patients (p thyroid surgery can be useful, easy available, and a low-cost tool in prediction of preoperatively undiagnosed PTC in patients with BTD.

    2014-01-01

    Full Text Available Metabolic syndrome (MetS is a well-recognized cluster of cardiovascular (CV risk factors including obesity, hypertension, dyslipidemia, and hyperglycaemia, closely associated with an increased risk of forthcoming cardiovascular disease and type 2 diabetes mellitus. Emerging evidence indicates that benign prostate hyperplasia (BPH and its related lower urinary tract symptoms (LUTS represent other clinical conditions frequently observed in subjects with MetS. Several modifiable factors involved in MetS determinism, such as inadequate diet, lack of physical exercise, and smoking and drinking behaviours are emerging as main contributors to the development of BPH. The pathogenetic mechanisms underlying the connection between MetS and BPH have not been completely clarified. MetS and its components, hypogonadism, and prostate inflammation probably play an important role in inducing BPH/LUTS. Although historically considered as a “normal” consequence of the aging process, BPH/LUTS should now be faced proactively, as a preventable disorder of the elderly. Type of diet and level of physical activity are now considered important factors affecting prostate health in the aging male. However, whether physical exercise, weight loss, and modifications of dietary habit can really alter the natural history of BPH/LUTS remains to be determined. Further research is advisable to better clarify these points.

    In-vivo diagnoses of thyroid diseases can be carried out using /sup 123/I, /sup 131/I, and /sup 99/sup(m)Tc-pertechnetate. For the thyroid scintiscan, /sup 99/sup(m)Tc-pertechnetate or /sup 123/I are used. Some functional parameters can be determined using /sup 99/sup(m)Tc-pertechnetate, but iodine is more accurate, so that thyroid clearance examinations with /sup 123/I are rapidly gaining importance. However, the iodine turnover in the thyroid can only be determined by a several-days' test using /sup 131/I. The available techniques of diagnosis are employed in several steps. Most thyroid diseases can already be diagnosed on the basis of the hormone parameters and a thyroid scan; otherwise, a TRH test and suppression and functional studies will be necessary. Treatment of enthyroid struma is limited to inoperable cases with functional blockage or compression of the trachea. In the treatment of diffuse hyperthyroidism, doses should be exact enough to counteract the hyperthyroid metabolism without inducing hypothyroidism. With exact doses, a second radioiodine therapy will only be necessary in about 40% of all cases. High doses should not be applied in the treatment of hyperthyroidism unless it is a case of excessive clinical hyperthyroid somatics as the risk of hypothyroidism is high. The diagnostic problem of autonomous adenoma is the highly varying hormone activity. The intention of radioiodine therapy here is a functional elimination of the autonomous adenoma. Radioiodine resection is indicated in cases where there are several small autonomous adenomas or where the operability of the patient is limited.

    In preparation for an outcomes study of benign prostatic hyperplasia (BPH), two measures of disease-specific health status were developed to supplement a symptom score and overall health status measures. The symptom problem index (SPI) captures how troublesome patients find their urinary symptoms. The BPH impact index (BII) measures how much their urinary problems affect various domains of health. A prospective revalidation of the refined instruments (N = 108 BPH patients and 50 controls) documented that both indices had good internal consistency (Cronbach's alpha = 0.88 and 0.79, respectively) and test-retest (r = 0.88 for both) reliabilities, correlated strongly with symptom scores (r = 0.86 and 0.77), and discriminated between BPH and control subjects (receiver-operating characteristic areas = 0.87 and 0.85, respectively). These indices were nearly as responsive as symptom scores in 50 men actively treated for BPH, and much more responsive than a non-disease-specific General Health Index (GHI), a Mental Health Index (MHI), and an Activity Index (AI). Finally, these measures capture most of the health status significance of BPH symptoms. In linear regression models constructed to predict scores on the GHI, MHI, and AI, symptom scores added little explanatory power to the SPI and, particularly, to the BII. These measures help clarify how BPH affects overall health status and function. Such measures have an important role to play in studies of the outcomes of treatment for BPH, and probably for other conditions that interfere with health status and function.

    This retrospective study of elective pneumonectomy for complicated inflammatory lung disease was done to define modern-day mortality and morbidity. One hundred twenty-four patients received elective pneumonectomy. Patient ages ranged from 6 months to 71 years. Past, recurrent, or new pulmonary tuberculosis was present in 107 patients (86.3%). Clinical presentation involved recurrent infections or severe suppurative sequelae (abscess, empyema). Forty-seven patients had chronic hemoptysis and 25 patients had past or recent massive hemoptysis (> 600 ml of hemoptysis fluid within 24 hours). Nutritional deficiencies were common. One hundred six patients (85.5%) had end-stage destroyed lungs. Evaluative bronchoscopy showed inflammatory endobronchial changes in 106 patients (85.5%), bronchial strictures in 4, and indolent endobronchial tumor in 2. Lung separation was by double-lumen tube in 96 patients, single lung-single tube in 6, bronchus blocker in 6, and prone posture in 9. Extrapleural pneumonectomy was done in 83 patients (66.9%). Fifty-seven of these procedures were left sided and 26 were right sided. Standard transpleural pneumonectomy was done in 41 patients (33.1%): 30 left sided and 11 right sided. Nine pneumonectomies were conducted with the patient in the prone position. Four patients had completion pneumonectomy. Hospital mortality was three deaths (2.4%). Morbidity included postpneumonectomy empyema in 19 patients (15.3%). Seven postoperative bronchopleural fistulas occurred. Empyema in most patients was managed by open pleural drainage (thoracostoma) and later space closure. Pneumonectomy proved effective therapy with low mortality but postpneumonectomy empyema posed serious morbidity.

    Purpose: Since the 20{sup th} century, radiotherapy (RT) has been used for treatment of symptomatic splenomegaly (SM). SM occurs in association with hematologic disorders. The purpose of this analysis was to determine the indication, treatment concepts, and efficiency of RT. Material and Methods: Clinical features, treatment concepts, and outcome data during the past 20 years were analyzed. Endpoints were pain relief, symptomatic and hematological response, and treatment-related side effects. Results: From 1989-2009, a total of 122 patients received 246 RT courses because of symptomatic SM. Overall 31 patients had chronic myelogenous leukemia (CML), 37 had chronic lymphocytic leukemia (CLL), 23 had osteomyelofibrosis (OMF), 17 had polycythemia vera (PV), 5 had acute myelogenous leukemia, 4 had idiopathic thrombocytopenic purpura (ITP), 3 had non-Hodgkin lymphoma (NHL), and 2 had multiple myeloma (MM). Patients were treated with {sup 60}Co gamma rays or 5-15MV photons. The fraction size ranged from 10-200 cGy and the total dose per treatment course from 30-1600 cGy. Significant pain relief was achieved for 74.8% of the RT courses given for splenic pain. At least 50% regression was attained for 77% of the RT courses given for SM. 36 patients died within 2 months due to the terminal nature of their disease. Of the RT courses applied for cytopenia, 73.6% achieved a significant improvement of hematological parameters and reduction of transfusion need. Notable hematologic toxicities were reported < EORTC/RTOG II . Conclusion: The present analysis documents the efficacy of RT. In addition, RT as a palliative treatment option for symptomatic SM should not be forgotten. (orig.)

    Full Text Available Hirayama's disease (HD is frequently found in Asia, and is rarely referred among westerners. It affects young people with higher incidence in males. It is a focal distal amyotrophy with unilateral or asymmetric bilateral involvement of C7, C8 and T1 innervated muscles. HD appears sporadically and has a benign evolution with clinical stabilization in around one year. We report four young male patients with clinical and electrophysiological alterations described in HD, which were followed-up during 5 years. Electromyographic findings were indicative of lower motor neuron involvement. We analyzed cervical MRI aiming at understanding if a questionable spinal cord compression could be implicated in the pathogenesis, but no abnormality was verified. In view of its clinical, and EMG characteristics, HD is no more than a benign monomelic amyotrophy (BMA clinical variant, and not a specific disease. This eponym could be considered only for the distal upper limb variant (Hirayama's variant of the BMA.

    Roxatidine (150 mg, 312 patients) was compared with ranitidine (300 mg, 308 patients) in a randomized, double-blind, parallel-group, 6-week therapeutic study for the treatment of patients with uncomplicated, benign gastric ulcer disease. The study end points (verified by using endoscopy results) were fully healed ulcers at 4 or 6 weeks. The results of roxatidine therapy were comparable to those of ranitidine therapy: healing rates of 52% and 54% at week 4 and 77% and 76% at week 6 were recorded for roxatidine and ranitidine, respectively. The drugs produced comparable reductions in ulcer diameters and decreases in abdominal pain. Adverse events associated with both roxatidine (27%) and ranitidine (28%) were headache, diarrhea, and dizziness; rash was associated in 6 of 8 cases and in only 1 case with roxatidine. In this trial, roxatidine 150 mg once daily was as efficacious and safe as ranitidine 300 mg once daily for treatment of patients with uncomplicated, benign gastric ulcer disease.

    Full Text Available Abstract Background Currently, data are not available concerning a safe insufflation pressure that provides a proper view of the surgical field without adverse metabolic and hemodynamic changes in humans undergoing the robot-assisted thyroidectomy bilateral axillo-breast approach (BABA using the da Vinci robotic surgical system. The purpose of this study was to determine the optimal carbon dioxide (CO2 insufflation pressure in patients with various benign and malignant thyroid diseases when using the da Vinci robotic surgical system. Methods A total of 32 patients underwent thyroid surgery at 6 (n = 15, 9 (n = 15, and 12 (n = 2 mmHg. The partial pressure of carbon dioxide (PaCO2, pH, cardiac output, heart rate, and mean arterial pressure were measured at baseline, 30 min and 1, 1.5, and 2 hours after CO2 insufflation, and 30 min after desufflation. Results CO2 insufflation of 12 mmHg caused severe facial subcutaneous emphysema, hypercarbia, and acidosis during robot-assisted thyroidectomy with BABA. The study was stopped before completion for the patients’ safety in accordance with the study protocol. Applying 6- or 9- mmHg of CO2 insufflation pressure caused increases in PaCO2 and decreases in arterial pH. However, vital signs were stable and pH and PaCO2 were within the physiologic range during the surgery in the 6- and 9-mmHg groups. Conclusions We propose that a CO2 insufflation pressure under 10 mmHg in robot-assisted thyroidectomy with BABA is the optimal insufflation pressure for patient safety.

    A 25-year-old woman presented in the third trimester of pregnancy with severe abdominal pain in the lower right abdominal quadrant. Differential diagnosis included urolithiasis, adnexal torsion and appendicitis. A definitive diagnosis could not be made based on clinical and laboratory examination. Ultrasonography revealed a 3-cm cyst in the lower right abdomen, which was considered unlikely to cause abdominal pain. During laparotomy, adnexal torsion was found, which was deemed to be the cause of the abdominal pain. The twisted portion was uncoiled and the dark-coloured cyst was extirpated. The cyst was determined to be a cystic adenoma. Adnexal torsion is rarely caused by cysts smaller than 5 cm, especially in the third trimester. Emergency laparoscopyllaparotomy should be performed if adnexal torsion is suspected to confirm the diagnosis and uncoil the twist to prevent ovarian damage. Adnexal torsion should be considered in the differential diagnosis of acute abdominal pain in the third trimester of pregnancy.

  1. Radioiodine therapy of benign thyroid diseases: Graves' disease - current aspects; Radioiodtherapie gutartiger Schilddruesenerkrankungen: Morbus Basedow - aktuelle Aspekte

    2005-06-01

    Radioiodine therapy is a reliable and cost-effective alternative to medical treatment of Graves' hyperthyroidism. Current recommendations favour a risk-adapted therapeutic procedure. Medical treatment is preferred in patients with a low risk of relapse which are characterised by the combination of female gender, age of onset above 40 years, thyroid volume below 40 ml and TSH-receptor antibodies below 10 U/l. Because of the poor remission rate with medical treatment in patients at less than 40 years of age, male gender, thyroid volume above 40 ml and TSH receptor antibodies above 10 U/l, it is suggested that definitive treatment with radioiodine or surgery should be considered soon after disease presentation. Analysis of cost-effectiveness clearly favour ablative radioiodine treatment. Ablative treatment is even more favourable in terms of early resumption of a normal life style of the hyperthyroid patient. Recent publications suggest further an adaptation of the tissue-absorbed dose to the pre-treatment thyroid volume using Marinelli's formula to achieve thyroid ablation with a single radioiodine treatment.

    Ming Zhang

    Full Text Available BACKGROUND: The scarcity of grafts available necessitates a system that considers expected posttransplant survival, in addition to pretransplant mortality as estimated by the MELD. So far, however, conventional linear techniques have failed to achieve sufficient accuracy in posttransplant outcome prediction. In this study, we aim to develop a pretransplant predictive model for liver recipients' survival with benign end-stage liver diseases (BESLD by a nonlinear method based on pretransplant characteristics, and compare its performance with a BESLD-specific prognostic model (MELD and a general-illness severity model (the sequential organ failure assessment score, or SOFA score. METHODOLOGY/PRINCIPAL FINDINGS: With retrospectively collected data on 360 recipients receiving deceased-donor transplantation for BESLD between February 1999 and August 2009 in the west China hospital of Sichuan university, we developed a multi-layer perceptron (MLP network to predict one-year and two-year survival probability after transplantation. The performances of the MLP, SOFA, and MELD were assessed by measuring both calibration ability and discriminative power, with Hosmer-Lemeshow test and receiver operating characteristic analysis, respectively. By the forward stepwise selection, donor age and BMI; serum concentration of HB, Crea, ALB, TB, ALT, INR, Na(+; presence of pretransplant diabetes; dialysis prior to transplantation, and microbiologically proven sepsis were identified to be the optimal input features. The MLP, employing 18 input neurons and 12 hidden neurons, yielded high predictive accuracy, with c-statistic of 0.91 (P<0.001 in one-year and 0.88 (P<0.001 in two-year prediction. The performances of SOFA and MELD were fairly poor in prognostic assessment, with c-statistics of 0.70 and 0.66, respectively, in one-year prediction, and 0.67 and 0.65 in two-year prediction. CONCLUSIONS/SIGNIFICANCE: The posttransplant prognosis is a multidimensional nonlinear

    Full Text Available The contribution of positron emission tomography/computed tomography (PET/CT with 18F-fludeoxyglucose (FDG in evaluating ovarian cancer recurrence even after a prolonged disease-free interval, and in therapy response is well-described. Calcifications observed in CT, although usually attributed to benign conditions, may actually represent active disease. Such an example of calcified formations is psammoma bodies. We present a case of 56-y. o. patient with ovarian cancer relapse at the supraclavicular area 18 years after complete response and disease-free interval. The patient received chemotherapy and underwent 18F-FDG-PET/CT for the evaluation of treatment response. Both CT corrected and uncorrected PET images showed hypermetabolism in the massively calcified lymph nodes in the neck, mediastinum, axilla and abdomen, indicative of active residual disease

    Full Text Available Background. The Chernobyl Nuclear Power Plant (CNPP accident exposed a large number of inhabitants to internal 131I radiation. The associations between internal 131I exposure and thyroid autoimmunity and benign thyroid diseases remain controversial in the population living in the contaminated area around the CNNP. In this study, we evaluate the association of 131I with benign thyroid diseases. Methods. We compared the prevalence of Anti-Thyroid Autoantibodies (ATAs, thyroid function, and prevalence of thyroid ultrasound finding outcomes in 300 residents of the contaminated area of Ukraine who were 0–5 years of age at the time of the CNPP accident (group 1 and 300 sex-matched residents who were born after the accident (group 2. Results. We did not find any differences of the prevalence of Antithyroglobulin Antibodies (TGAb positive, Antithyroid Peroxidase Antibodies (TPOAb positive, and TGAb and/or TPOAb positive between the study groups. (11.7% vs 10.3%; p = 0.602, 17.3% vs 13.0%; p = 0.136, 21.0% vs 17.3%; p = 0.254, respectively; after adjusting for age and sex, the prevalence was not associated with the 131I exposure status in the study groups. The prevalence of subclinical and overt hypothyroidism cases was not significantly different (p = 0.093 and p = 0.320 in the two groups, nor was the prevalence of goiter (p = 0.482. On the other hand, the prevalence of nodules was significantly higher in group 1 (p = 0.003, though not significantly so after adjustment for age and sex. Discussion. Working 26–27 years after the CNNP accident, we found no increased prevalence of ATAs or benign thyroid diseases in young adults exposed to 131I fallout during early childhood in the contaminated area of Ukraine. Long-term follow-up is needed to clarify the effects of radiation exposure on autoimmunity reaction in the thyroid.

    Full Text Available Objective: To assess some clinical characteristics of patients who were treated for adnexal torsion during pregnancy. Methods: Medical records of 14 pregnant women with adnexal torsion who were surgically treated at our hospital between 1st January 2011 to 30th October 2015 were screened. In addition to the demographic features obtained from medical records, presenting complaints, physical examination and ultrasonographic findings, type of surgery, histopathologic findings, route of deliveries and complications were all recorded. Results: Mean age of patients included in the study was 27.8 ± 3.9 years, mean gravidity was 2.8 ± 1.8 and mean gestational age was 14.4 weeks. Most commonly seen complaint was pelvic pain followed by emesis and vomiting. All participants underwent abdominal surgery showing an adnexal mass with a mean volume of 48.4 ± 12.1 cm2. Also all participants underwent Doppler ultrasound assessment showing decreased ovarian blood flow. Among 14 patients, 3 of them were managed by laparoscopy while remaining was treated by laparotomy. Detorsion and cystectomy were performed in 10 patients while detorsion was performed in 3 patients, in 1 patient after detorsion no blood flow was observed therefore salpingo-oophorectomy was performed due to overt necrotic appearance. Most commonly seen histopathologic type was mature cystic teratoma. No operative complication was observed. Conclusion: Adnexal torsion should be kept in mind in pregnant presenting with acute abdominal pain. Early diagnosis and treatment are important for organ preserving surgery.

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

    Full Text Available Abstract Background Thyroid physiology is closely related to oxidative changes. The aim of this controlled study was to evaluate the levels of nutritional anti-oxidants such as vitamin C, zinc (Zn and selenium (Se, and to investigate any association of them with parameters of thyroid function and pathology including benign and malignant thyroid diseases. Methods This controlled evaluation of Se included a total of 1401 subjects (1186 adults and 215 children distributed as follows: control group (n = 687, benign thyroid disease (85 children and 465 adults; malignant thyroid disease (2 children and 79 adults. Clinical evaluation of patients with benign thyroid disease included sonography, scintigraphy, as well as the determination of fT3, fT4, TSH, thyroid antibodies levels, Se, Zn, and vitamin C. Besides the routine oncological parameters (TG, TSH, fT4, ultrasound Se was also determined in the cases of malignant disease. The local control groups for the evaluation of Se levels were taken from a general practice (WOMED as well as from healthy active athletes. Blood samples were collected between 8:00 and 10:30 a.m. All patients lived in Innsbruck. Statistical analysis was done using SPSS 14.0. The Ho stated that there should be no differences in the levels of antioxidants between controls and thyroid disease patients. Results Among the thyroid disease patients neither vitamin C, nor Zn nor Se correlated with any of the following parameters: age, sex, BMI, body weight, thyroid scintigraphy, ultrasound pattern, thyroid function, or thyroid antibodies. The proportion of patients with benign thyroid diseases having analyte concentrations below external reference cut off levels were 8.7% of cases for vitamin C; 7.8% for Zn, and 20.3% for Se. Low Se levels in the control group were found in 12%. Se levels were significantly decreased in cases of sub-acute and silent thyroiditis (66.4 ± 23.1 μg/l and 59.3 ± 20.1 μg/l, respectively as well as in

    Cylindromas are rare adnexal skin tumours that usually occur in the head and neck area. This article reports a case of benign cylindroma arising in the external auditory canal. A 75-year-old man presented with a 3-month history of right aural fullness; no other symptoms were reported. Ear microscopy examination revealed a skin mass on the floor of the external ear canal. Α CT scan of the skull showed a well-circumscribed soft tissue mass, with no signs of underlying cortical bone erosion. Tumour resection through an endaural approach was performed. Histological examination revealed a benign cylindroma with margins free of tumour, so that no further treatment was necessary. 8 months after surgery the patient is asymptomatic with normal findings in the ear microscopy examination. Benign cylindroma has a high recurrence rate and can undergo malignant transformation. Therefore, complete surgical removal and close follow-up are of great importance.

    Pilot studies of combined therapies treating benign nodular goiters reported promising results. The aim of this study was to investigate the effectiveness of combined microwave ablation (MWA) and radioiodine therapy (RIT) with a special focus on thyroid function at the 3-month follow-up. 15 patients (median age: 55 years) with a large goiter and benign thyroid nodules or Graves' disease were treated with the combined therapy. Serum levels of triiodothyronine (T3), thyroxine (T4), thyrotropin (TSH), thyroglobuline (Tg) and, additionally, antibody levels against thyroglobulin (TgAb), thyrotropin receptors (TRAb) and thyroid peroxidase (TPOAb) were measured at enrollment, post MWA and at the 3-month follow-up (3MFU). Furthermore, the goiter volume, I-131 dose and hospitalization time were analyzed to evaluate effectiveness. MWA was operated under local anesthesia with a system working in a wavelength field of 902 to 928 MHz. TSH, T4, T3 and Tg did not change at 3MFU, except for in two patients in whom the initial TSH levels improved to normal thyroid functioning levels at follow-up. One of the patients developed a high TRAb-level that receded back into the normal range. At 3MFU, the combined therapy showed a mean thyroid volume reduction of 26.4 ml ± 7.9 ml (30.5 % ± 4.6 % (p < 0.05)). By utilizing the combined therapy, administered activity could be reduced by 26.6 % ± 4.8 % (p < 0.05) and hospitalization time by 30.9 % ± 19.9 % (p < 0.05). The data confirmed the effectiveness of the combination of MWA with RIT. The combined therapy is an innovative and conservative approach and could become a safe alternative to surgery for the treatment of very large benign nodular goiters. Due to the short follow-up and the limited number of patients, further studies will be necessary.

    Screening for prostate cancer remains unsatisfactory. Recent studies have examined the cancer diagnostic/prognostic values of various acute phase proteins, such as haptoglobin. We describe here a novel method of surface plasmon resonance (SPR) based on multi-sequential analysis with SNA-1, AAL, and PHA-L(4) lectin, to estimate the glycosylation status of haptoglobin in sera of patients with prostate cancer (n=15), benign prostate disease (BPD) including benign prostatic hypertrophy (n=20), and normal subjects (n=11). The SPR-based analysis involves the use of anti-haptoglobin as ligand and dilution of the analyte to 1400-fold and filtration, followed by detection of the sugar chain by lectin solution. The normalized RU of lectin to haptoglobin represents the binding amount of lectin divided by that of haptoglobin. The normalized RU by SNA-1 of the prostate cancer group was significantly higher than those of the control and BPD group. SNA-1 detected NeuAcα2,6 in a biantennary sugar chain, whose content was the highest among the major glycoproteins in serum. Serum samples diluted about 7000-fold were subjected to microanalysis at 10 ng/μl and 10 μl/min for 4 min. The combination of SNA-1 and haptoglobin by SPR multi-sequential analysis offered the most accurate diagnosis of prostate cancer without any modification of serum glycoproteins.

    We report a single case of masquerade glaucoma caused by increased episcleral venous pressure from adnexal lymphoma. The patient presented as a referral for unilateral glaucoma with intraocular pressures (IOPs) consistently >40 mm Hg (right eye). We present data conclusively demonstrating extranodal marginal zone lymphoma of mucosa-associated lymphoid tissue in the involved eye, and provide an account of the treatment of the tumor with sustained regression and complete resolution of his elevated IOP. We conclude with a discussion of the proposed mechanism. This case serves as a reminder that unilateral open-angle glaucoma can be a sign of indolent ocular adnexal lymphoma. The case also provides a useful model for increased IOP with orbital lesions.

    Full Text Available Acute-onset pelvic pain is an extremely common symptom in premenopausal women presenting to the emergency department. After excluding pregnancy in reproductive-age women, ultrasonography plays a major role in the prompt and accurate diagnosis of adnexal causes of acute pelvic pain, such as hemorrhagic ovarian cysts, endometriosis, ovarian torsion, and tubo-ovarian abscess. Its availability, relatively low cost, and lack of ionizing radiation make ultrasonography an ideal imaging modality in women of reproductive age. The primary goal of imaging in these patients is to distinguish between adnexal causes of acute pelvic pain that may be managed conservatively or medically, and those requiring emergency/urgent surgical or percutaneous intervention.

Presentamos el caso de una mujer diagnosticada de Enfermedad de Madelung refiriendo engrosamiento progresivo de la lengua. Presentaba dificultad para tragar, disartria y disnea con el decúbito.Madelung´s disease, or benign symmetric lipomatosis, is an uncommon disease characterized by non-encapsulated accumulations of fat in a symmetric manner around the neck and shoulders. This uncommon disease predominantly affects men between the ages of 30 and 60 and it has a 15:1 ratio. There is a strong correlation with alcohol abuse. Nonalcoholics and women can also be affected although this is rare. We report the case of a woman diagnosed with Madelung’s disease, who described a gradual swelling of the tongue. She had difficulty swallowing, dysarthria and dyspnea while sleeping.

    Full Text Available Objective: To evaluate the feasibility and safety of laparoscopic surgery for treating adnexal masses during the first trimester of pregnancy. Study Design: An observational study of a prospective collection of data of all pregnant women who underwent laparoscopic surgery for adnexal masses during the first trimester of pregnancy between January 1999 and November 2012 at the Obstetrics and Gynecology Department of the Italian Hospital of Buenos Aires, Buenos Aires, Argentina was performed. Results: A total of 13 women were included. The median (range gestational age at the moment of surgical procedure was 7 weeks (range: 5-12 weeks. The main indication of surgery was cyst torsion in four cases (30.7% and rupture of ovarian cysts in four cases (30.7%. Other indications included persistent ovarian cyst in three patients (23% and heterotopic pregnancy in two cases (15.3%. Neither surgical complications nor spontaneous abortions occurred in any of the cases and the post-operative period was uneventful in all the cases. No cases of intrauterine growth retardation, preterm delivery, congenital defects, or neonatal complications were registered. Conclusion: The treatment of complicated adnexal masses by laparoscopic surgery during the first trimester of pregnancy appears to be a safe procedure both for the mother and for the foetus. Additional research on a larger number of cases is still needed to support these conclusions.

    Full Text Available Abstract Background It remains unknown whether primary ocular adnexal extranodal marginal zone B-cell lymphoma of mucosa-associated lymphoid tissue (MALT lymphoma is a homogeneous entity, as there are few reports of the results of cytogenetic or molecular analyses of these tumors. Methods We performed interphase fluorescence in situ hybridization (FISH analysis to detect translocations and aneuploidy in 34 cases of primary ocular adnexal MALT lymphoma, and reviewed the histopathological findings. Correlations between the results of FISH analysis, the histopathological features and the clinical data were also analyzed. Results Among the 34 cases, FISH analysis revealed t(14;18(q32;q21 in one case, trisomy 3 in 21 cases (62%, and trisomy 18 in 16 cases (47%. The cases with trisomy 18 had significantly more prominent lymphoepithelial lesions (LELs and less nodularity in the tumors. In regard to the clinical correlations, tumors with trisomy 18 were observed predominantly in females and younger patients; also, in the majority of the cases, the tumor was of conjunctival origin. All the cases with recurrence showed trisomy 18 in the tumor. Conclusion Primary ocular adnexal MALT lymphoma is a significantly heterogeneous entity. Cases with trisomy 18 may have unique clinicopathological features.

    Full Text Available Abstract Background Minimal invasive breast biopsy is standard care for the diagnosis of suspicious breast lesions. There are different vacuum biopsy (VB systems in use. The aim of the study was to determine the differences between the 8-gauge and the 11-gauge needle with respect to a diagnostic reliability, b complication rate and c subjective perception of pain when used for vacuum-assisted breast biopsy. Methods Between 01/2000 and 09/2004, 923 patients at St. Josefs-Hospital Wiesbaden underwent VB using the Mammotome® (Ethicon Endosurgery, Hamburg. Depending on preoperative detection, the procedure was performed under sonographic or mammographic guidance under local anaesthesia. All patients included in the study were followed up both clinically and using imaging techniques one week after the VB and a second time after a median of 41 months. Excisional biopsy on the ipsilateral breast was an exclusion criteria. Subjective pain scores were recorded on a scale of 0 – 10 (0 = no pain, 10 = unbearable pain. The mean age of the patients was 53 years (30 – 88. Results 123 patients were included in the study in total. 48 patients were biopsied with the 8-gauge needle and 75 with the 11-gauge needle. The use of the 8-gauge needle did not show any significant differences to the 11-gauge needle with regard to diagnostic reliability, complication rate and subjective perception of pain. Conclusion Our data show that there are no relevant differences between the 8-gauge and 11-gauge needle when used for VB. Under sonographic guidance, the use of the 8-gauge needle is recommended for firm breast tissue due to its sharp scalpel point and especially for complete removal of benign lesions. We did not find any advantages in the use of the larger 8-gauge needle compared to the 11-gauge needle in the mammography setting. The utilisation costs of the 8-gauge needle are somewhat higher.

    自从引入腹腔镜手术,普遍认为应用腹腔镜进行附件手术会取代开腹手术.然而事实证明,虽然腹腔镜手术开展了20多年,开腹附件手术仍未被淘汰.这份来自澳大利亚各州及地区关于附件手术病人的资料显示了在澳大利亚应用腹腔镜进行附件手术的变化趋势.同时还有一份来自悉尼利物浦医院病人的资料同样也说明了在附件手术中决定选择何种手术方式的影响因素.我们的研究认为,在所有附件手术中,应用腹腔镜进行手术已经增加到90%,然而大概还有10%的病人需要开腹手术.全国范围内附件手术在手术方式选择上的变化趋势受政府医疗保险政策变化的影响.利物浦医院的当地资料显示,不同个体在手术方式选择上的变化趋势与澳大利亚全国范围内附件手术方式变化趋势不同,是由于管理人员和资金的改变引起的.从病人利益角度考虑,一项对妇科医师问卷调查显示,下述因素是导致医师选择开腹手术的重要原因:术前怀疑肿瘤是恶性的;医生缺少腹腔镜技术的培训;急诊状况下.术前应用敏感性高和特异性好的肿瘤标志物改善附件恶性肿瘤术前诊断的准确性有利于更多病人进入腔镜组而不是开腹组,同时医师经过良好的训练和提高手术技术也可以在不久的将来促进腹腔镜手术的发展.%Since the introduction of laparoscopic surgery, it was postulated that laparoscopie surgery for adnexal diseases would replace all abdominal adnexal surgery. However, it is now evident that after two decades of practicing laparoscopic surgery, open abdominal adnexal surgery is still being performed. This study of patients with adnexal surgery from all States and Territories of Australia will reveal the trend of laparoscopic adnexal surgery in Australia and an analysis of the patients' data from the Liverpool Hospital in Sydney has also helped to reveal the factors influencing

    The development of hepatocellular adenomas in the liver of patients with glycogen storage disease type I is a well-known complication of the disease. Surgical procedures and perioperative managements described so far have reported persistent and important morbidity. We report here a series of six patients (three males and three females) who underwent hepatic resection, and we propose a new hemostatic management protocol comprising glucose infusion, corticosteroids, desmopressin, and antifibrinolytic drugs, used to prevent efficaciously hepatic hemorrhage due to glycogen storage disease (GSD) platelet dysfunction.

    Tyrosine protein kinase (TPK) activity is associated to malignant cellular transformation. This work compares TPK activity in 27 surgical biopsy samples of mammary carcinoma, 10 samples of fibroadenomas, 13 samples of fibrocystic breast disease and 27 samples of normal mammary tissue. TPK activity was determined in tissue homogenates using (Val5) angiotensin II as exogenous substrate. In samples of mammary carcinoma, TPK activity was 33.86 +/- 31.98 pmol P32/mg protein/30 min. This value was significantly higher that those observed in fibrocystic disease (3.92 +/- 2.35), fibroadenomas (13.86 +/- 10.9) and normal tissue (3.56 +/- 3.02).

    Background: radiogenic malignancies require cure of the primary disease and a prolonged survival. The introduction of high-volt technology in the 1950s and 1960s made radical radiotherapy feasible and successful in terms of higher cure rates and longer survival. We are already in a time when a higher number of patients with radiogenic secondary malignancies must be expected. Case report: a 12-year-old boy is reported who suffered from an advanced nasopharynx carcinoma and was treated with radical irradiation in 1983. 15 years later he developed a rare microcystic adnexal carcinoma of the auditory canal inside the volume of the target dose. The secondary malignant neoplasm was resected and required another radiation treatment (1 Gy b.i.d.) due to involved margins. Discussion and literature review: the entity of microcystic carcinoma is discussed with a review of the literature on biology, diagnosis, and treatment. (orig.)

    2011-01-01

    Full Text Available Background. This study is a review of the incidence, clinical characteristics, and management of secondary BPPV. The different subtypes of secondary BPPV are compared to each other, as well as idiopathic BPPV. Furthermore, the study highlights the coexistence of BPPV with other inner ear pathologies. Methods. A comprehensive search for articles including in the abstract information on incidence, clinical characteristics, and management of secondary BPPV was conducted within the PubMed library. Results. Different referral patterns, different diagnostic criteria used for inner ear diseases, and different patient populations have led to greatly variable incidence results. The differences regarding clinical characteristics and treatment outcomes may support the hypothesis that idiopathic BPPV and the various subtypes of secondary BPPV do not share the exact same pathophysiological mechanisms. Conclusions. Secondary BPPV is often under-diagnosed, because dizziness may be atypical and attributed to the primary inner ear pathology. Reversely, a limited number of BPPV patients may not be subjected to a full examination and characterized as idiopathic, while other inner ear diseases are underdiagnosed. A higher suspicion index for the coexistence of BPPV with other inner ear pathologies, may lead to a more integrated diagnosis and consequently to a more efficient treatment of these patients.

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

    Proliferating epithelial structures were studied immunomorphologically in 16 cases of fibrocystic disease and benign tumours. Monoclonal antibodies were used to prekeratin (PK) C12, normally specific for the lining epithelium, to prekeratin (PK) E3 and to the protein of intermediate filaments in mesenchymal cells--vimentin, normally specific for myoepithelium. The immunofluorescent analysis of the most common proliferating structures has shown that there are elements with a variable combination of PK C12, PK E3 and vimentin among the proliferating cells. While there are cells similar to normal lining epithelium (PK C12) or myoepithelium (PK E3) and/or vimentin), many cells have no analogues either among normal cells, or among cells from ductal, lobular and tubular tumour forms. Since in the most common forms of breast cancer only cells containing PK C12 were found, the immunofluorescent study with the application of monoclonal antibodies to PK C12, PK E3 and vimentin can be recommended in difficult and dubious cases for the recognition of carcinogenic or dysplastic nature of morphologically similar proliferating structures.

    Full Text Available Smoke constituents can induce DNA adducts that cause mutations and lead to lung cancer. We have analyzed DNA adducts and polymorphisms in two DNA repair genes, for example, XRCC1 Arg194Trp and Arg399Gln genes and XRCC3 Thr241Met gene, in 34 lung cancer cases in respect to 30 subjects with benign lung cancer disease and 40 healthy controls. When the study population was categorized in base to the number of risk alleles, adducts were significantly increased in individuals bearing 3-4 risk alleles (OR=4.1 95% C.I. 1.28–13.09, P=.009. A significant association with smoking was noticed in smokers for more than 40 years carrying 3-4 risk alleles (OR=36.38, 95% C.I. 1.17–1132.84, P=.040. A not statistically significant increment of lung cancer risk was observed in the same group (OR=4.54, 95% C.I. 0.33–62.93, P=.259. Our results suggest that the analysis of the number of risk alleles predicts the interindividual variation in DNA adducts of smokers and lung cancer cases.

    A questionnaire was mailed in 3 years (1994, 1995, 1996) to all radiation facilities in Germany, which assessed equipment, indications, number of patients and treatment concepts. A total of 134 (88%) institutions returned all requested data: 22 in East and 112 in West Germany; 30 in university and 104 in community/private hospitals. The average data of each institution and of all institutions were analyzed for frequencies and ratios between different regions and institutions. A mean of 2 (range 1 to 7) megavoltage (Linac/Cobalt 60) and 1.4 (range 0 to 4) orthovoltage units were available per institution; 32 (24%) institutions had no orthovoltage equipment. A mean of 20,082 patients were treated per year: 456 (2%) for inflammatory diseases (221 hidradenitis, 78 nail bed infection, 23 parotitis, 134 not specified), 12,600 (63%) for degenerative diseases (2,711 peritendinitis humeroscapularis, 1,555 epicondylitis humeri, 1,382 heel spur, 2,434 degenerative osteoarthritis, 4,518 not specified), 927 (5%) for hypertrophic diseases (146 Dupuytren's contracture, 382 keloids, 155 Peyronie's disease, 244 not specified), 1,210 (6%) for functional disorders (853 Graves' orbitopathy, 357 not specified), and 4,889 (24%) for other disorders (e.g. 3,680 heterotopic ossification prophylaxis). In univariate analysis, there were significant geographical (West vs East Germany) differences in the use of radiotherapy for inflammatory and degenerative disorders and institutional differences (university vs community/private hospitals) in the use of radiotherapy for hypertrophic and functional disorders (p<0.05). The prescribed dose concepts were mostly in the low dose range (<10 Gy), but varied widely and inconsistently within geographic regions and institution types.

    Full Text Available Adnexal mass in postmenopausal woman is a diagnostic challenge. Due to the age, concern for malignancy is always there. At times however, despite the usual investigations, diagnosis remains elusive till histopathology report is at hand. To add to the enigma, ovarian masses in postmenopausal woman may remain silent till quite large and even among those which are symptomatic a predictable presentation may not be there. A careful clinical examination with a high degree of suspicion of clinical variants is thus recommended while dealing with ovarian tumors in postmenopausal women.

  16. Enhanced discrimination of malignant from benign pancreatic disease by measuring the CA 19-9 antigen on specific protein carriers.

    Directory of Open Access Journals (Sweden)

    Tingting Yue

    Full Text Available The CA 19-9 assay detects a carbohydrate antigen on multiple protein carriers, some of which may be preferential carriers of the antigen in cancer. We tested the hypothesis that the measurement of the CA 19-9 antigen on individual proteins could improve performance over the standard CA 19-9 assay. We used antibody arrays to measure the levels of the CA 19-9 antigen on multiple proteins in serum or plasma samples from patients with pancreatic adenocarcinoma or pancreatitis. Sample sets from three different institutions were examined, comprising 531 individual samples. The measurement of the CA 19-9 antigen on any individual protein did not improve upon the performance of the standard CA 19-9 assay (82% sensitivity at 75% specificity for early-stage cancer, owing to diversity among patients in their CA 19-9 protein carriers. However, a subset of cancer patients with no elevation in the standard CA 19-9 assay showed elevations of the CA 19-9 antigen specifically on the proteins MUC5AC or MUC16 in all sample sets. By combining measurements of the standard CA 19-9 assay with detection of CA 19-9 on MUC5AC and MUC16, the sensitivity of cancer detection was improved relative to CA 19-9 alone in each sample set, achieving 67-80% sensitivity at 98% specificity. This finding demonstrates the value of measuring glycans on specific proteins for improving biomarker performance. Diagnostic tests with improved sensitivity for detecting pancreatic cancer could have important applications for improving the treatment and management of patients suffering from this disease.

    2002-11-01

    The concept of the "incidentaloma," a totally asymptomatic nonfunctional tumor that is clinically and biochemically silent and discovered "incidentally" in a totally asymptomatic patient, is a by-product of the evolving diagnostic techniques of the last three decades. Various authors have used the concept for "incidental" findings during diagnostic workup for symptoms unrelated to adrenal disease, or for "incidental" adrenal tumors unrelated to symptoms that could potentially be of adrenal origin. "Incidentaloma" has been used to encompass a wide and heterogeneous spectrum of pathologic entities including adrenocortical and medullary tumors, benign or malignant lesions, hormonally active or inactive lesions, metastases, infections, granulomas, infiltrations, cysts and pseudocysts, hemorrhages, and pseudoadrenal masses. The term "incidentaloma" does not indicate whether the mass is functional, or malignant, or adrenocortical in origin. "Incidentaloma" has also appeared in the literature in reference to other endocrine organs such as pituitary, thyroid, and parathyroids, as well as the liver or kidney. We question the scientific justification for this neologism and suggest that it should be abolished. Questionable lesions should be clearly and simply described as "incidentally found."

    2016-01-01

    Background T-cadherin is an atypical glycosylphosphatidylinositol-anchored member of the cadherin superfamily of adhesion molecules. The role of T-cadherin in biology of the skin is poorly understood. Expression of T-cadherin in basal keratinocytes and dermal blood vessels of the healthy epidermis has been demonstrated, but studies on expression in skin appendages are rare. Methods We conducted an immunohistochemical analysis of T-cadherin expression in the epidermis and adnexal structures of normal skin. Results T-cadherin expression is restricted to basal keratinocytes of the epidermis. The basal cell layer of sebaceous glands was T-cadherin positive, whereas sebocytes were negative. Within apocrine glands, only myoepithelial cells were T-cadherin positive. In contrast, both the secretory coils and excretory ducts of eccrine glands were T-cadherin positive. In terminal hair follicles, the outer root sheath layers strongly expressed T-cadherin throughout different regions of the follicle, with the strongest immunoreactivity at the bulge and suprabulbar regions. T-cadherin and CK15 stem cell marker similarly localized within the bulge and suprabulbar region. T-cadherin and CD34 stem cell marker similarly localized at the suprabulbar level. Conclusion The specific patterns of T-cadherin expression in the epidermis and adnexal structures suggest an important guardian role in skin homeostasis. PMID:27904857

    2006-06-01

    Full Text Available Abstract Background A cohort study was conducted to examine the role of genetic polymorphisms in three estrogen metabolizing enzymes (COMT, CYP1A1, CYP1B1 and the two estrogen receptors (ESR1, ESR2 in the progression of benign breast disease (BBD to breast cancer. Methods Among participants in an ongoing cohort study, 1438 Caucasian women had a breast biopsy for BBD and were successfully genotyped for at least one of the polymorphisms examined in this study. Genotypes were determined using DNA extracted from blood specimens collected in 1989. Incident cases of breast cancer occurring subsequent to BBD diagnosis up to 2003 were identified through cancer registries. Results Among all participants, the ESR2 *5772G allele was associated with a significant decrease in the risk of breast cancer among women with BBD (Odds Ratio (OR 0.38; 95% Confidence Interval (CI 0.15, 0.96. Compared to the reference wild-type genotypes, marginally significant associations with the development of breast cancer were observed between carriers of the variant ESR1 – 104062T allele (OR 0.70, 95% CI 0.45, 1.09, the variant ESR2 *38A allele (OR 1.40; 95% CI 0.88, 2.25, and the variant CYP1B1 453Ser allele (OR 1.48, 95% CI 0.95, 2.32. Conclusion The results indicate that specific polymorphisms in the CYP1B1, ESR1, and ESR2 genes may play a role in progression of BBD to breast cancer among Caucasian women. Although additional studies are needed to confirm or refute our findings, these results suggest that genetic markers may aid in the identification of women who are at risk for progression of BBD to cancer.

    2016-02-01

    To assess the status of oxidative stress in benign prostate hyperplasia, a very common disease in older men which constitutes a public health problem in Jijel, prostate tissues were obtained by transvesical adenomectomy from 10 men with benign prostate hyperplasia. We measured the cytosolic levels of malondialdehyde (MDA) and glutathione (GSH) and cytosolic enzyme activities of superoxide dismutase, catalase, glutathione peroxidase and glutathione S-transferase. The development of benign prostate hyperplasia is accompanied by impaired oxidative status by increasing levels of MDA, depletion of GSH concentrations and a decrease in the activity of all the antioxidant enzymes studied. These results have allowed us to understand a part of the aetiology of benign prostate hyperplasia related to oxidative stress.

  4. Benign Metastatic Leiomyoma Presenting as a Hemothorax

    Directory of Open Access Journals (Sweden)

    Anna M. Ponea

    2013-01-01

    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.

    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.

    Objective To explore the value of dynamic contrast-enhanced MRI in the differential diagnosis of benign and malignant breast diseases. Methods Retrospective analysis was conducted on MRI data of 70 cases (78 breasts) with breast lesions confirmed pathologically during the period of January 2012 to June 2014, including 46 breasts of carcinoma and 32 breasts of benign diseases. MRI signs and enhanced parameters of benign and malignant breast lesions were observed, and specificity, sensitivity and accuracy were compared between dynamic contrast-enhanced MRI scan and MRI plain scan in diagnosis of breast cancer. Results The average age of patients with benign lesions was significantly lower (t=8. 225, P0. 05). Emax of malignant breast lesions was significantly higher than benign tumors, but Tmax and Slopemax were significantly lower than benign lesions ( t value was 10. 286, 11. 445 and 7. 236, all P0.05);②乳腺恶性病变峰值增强率(Emax)显著高于良性肿块,峰值时间(Tmax)、最大强化速率(Slopemax)显著低于良性病变(t值分别为10.286、11.445、7.236,均P<0.05);③乳腺恶性病变SI-Time曲线廓清型、平台型、渐进型分别为38例、6例、2例,良性病变分别为0例、5例、27例,两组比较SI-Time曲线类型分布差异有统计学意义(χ2=10.381,P<0.05);④MRI动态增强扫描检查乳腺恶性病变灵敏度、特异度及准确率分别为100%、96.88%、98.72%,均高于 MRI 平扫的78.26%、78.13%、78.20%,比较差异有统计学意义(χ2值分别为7.382、8.164、8.237,均P<0.05)。结论乳腺良恶性疾病动态增强MRI扫描具有特异性表现,具有较高的鉴别诊断参考价值。

    Developmental venous anomalies (DVAs), previously called venous angiomas, are the most frequently encountered cerebral vascular malformations. However, DVA is considered to be rather an extreme developmental anatomical variation of medullary veins than true malformation. DVAs are composed of dilated medullary veins converging centripetally into a large collecting venous system that drains into the superficial or deep venous system. Their etiology and mechanism are generally accepted that DVAs result from the focal arrest of the normal parenchymal vein development or occlusion of the medullary veins as a compensatory venous system. DVAs per se are benign and asymptomatic except for under certain unusual conditions. The pathomechanisms of symptomatic DVAs are divided into mechanical, flow-related causes, and idiopathic. However, in cases of DVAs associated with hemorrhage, cavernous malformations (CMs) are most often the cause rather than DVAs themselves. The coexistence of CM and DVA is common. There are some possibilities that DVA affects the formation and clinical course of CM because CM related to DVA is generally located within the drainage territory of DVA and is more aggressive than isolated CM in the literature. Brain parenchymal abnormalities surrounding DVA and cerebral varix have also been reported. These phenomena are considered to be the result of venous hypertension associated with DVAs. With the advance of diagnostic imagings, perfusion study supports this hypothesis demonstrating that some DVAs have venous congestion pattern. Although DVAs should be considered benign and clinically silent, they can have potential venous hypertension and can be vulnerable to hemodynamic changes. PMID:27250700

    Lesser degrees of terminal duct-lobular unit (TDLU) involution predict higher breast cancer risk; however, standardized measures to quantitate levels of TDLU involution have only recently been developed. We assessed whether three standardized measures of TDLU involution, with high intra/inter pathologist reproducibility in normal breast tissue, predict subsequent breast cancer risk among women in the Mayo benign breast disease (BBD) cohort. We performed a masked evaluation of biopsies from 99 women with BBD who subsequently developed breast cancer (cases) after a median of 16.9 years and 145 age-matched controls. We assessed three metrics inversely related to TDLU involution: TDLU count/mm(2), median TDLU span (microns, which approximates acini content), and median category of acini counts/TDLU (0-10; 11-20; 21-30; 31-50; >50). Associations with subsequent breast cancer risk for quartiles (or categories of acini counts) of each of these measures were assessed with multivariable conditional logistic regression to estimate odds ratios (ORs) and 95 % confidence intervals (CI). In multivariable models, women in the highest quartile compared to the lowest quartiles of TDLU counts and TDLU span measures were significantly associated with subsequent breast cancer diagnoses; TDLU counts quartile4 versus quartile1, OR = 2.44, 95 %CI 0.96-6.19, p-trend = 0.02; and TDLU spans, quartile4 versus quartile1, OR = 2.83, 95 %CI = 1.13-7.06, p-trend = 0.03. Significant associations with categorical measures of acini counts/TDLU were also observed: compared to women with median category of 25 acini counts/TDLU were at significantly higher risk, OR = 3.40, 95 %CI 1.03-11.17, p-trend = 0.032. Women with TDLU spans and TDLU count measures above the median were at further increased risk, OR = 3.75 (95 %CI 1.40-10.00, p-trend = 0.008), compared with women below the median for both of these metrics. Similar results were observed for combinatorial metrics of TDLU

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

    A. L. Valentini

    2012-01-01

    Full Text Available Ovarian masses present a special diagnostic challenge when imaging findings cannot be categorized into benign or malignant pathology. Ultrasonography (US, Computed Tomography (CT, and Magnetic Resonance Imaging (MRI are currently used to evaluate ovarian tumors. US is the first-line imaging investigation for suspected adnexal masses. Color Doppler US helps the diagnosis identifying vascularized components within the mass. CT is commonly performed in preoperative evaluation of a suspected ovarian malignancy, but it exposes patients to radiation. When US findings are nondiagnostic or equivocal, MRI can be a valuable problem solving tool, useful to give also surgical planning information. MRI is well known to provide accurate information about hemorrhage, fat, and collagen. It is able to identify different types of tissue contained in pelvic masses, distinguishing benign from malignant ovarian tumors. The knowledge of clinical syndromes and MRI features of these conditions is crucial in establishing an accurate diagnosis and determining appropriate treatment. The purpose of this paper is to illustrate MRI findings in neoplastic and non-neoplastic ovarian masses, which were assessed into three groups: cystic, solid, and solid/cystic lesions. MRI criteria for the correct diagnosis and characteristics for differentiating benign from malignant conditions are shown in this paper.

The patient was a 43-year-old female, who had presented with a plaque on the left upper lip for more than 2 years. Skin examination revealed a demarcated, skin-colored plaque measuring 2.5 cm in diameter with telangiectasia on the surface of the left upper lip. Skin biopsy showed that the tumor lied in the dermis, infiltrating deeply into the underlying nervous and muscle tissue. There were many ductal structures and a small number of ramified glands with apocrine features in the upper dermis, strands of basophilic epithelial component imbedded in a markedly hyalinized stroma in the mid and lower dermis, as well as small and round keratinous cysts in the lower dermis. Immunohistoehemistry revealed strong positive staining of the epithelial components with cytokeratin. The staining for CEA and epithelial membrane antigen (EMA) was noted in the superficial ducts and glands. S-100 stain showed the infiltration of peripheral nerve with cytokeratin-positive epithelial components. A diagnosis of microcystic adnexal carcinoma was made. The patient underwent an excisional surgery and was followed up.

    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.

    Although the pathogenesis of lower urinary tract symptoms, benign prostatic hyperplasia/benign prostatic enlargement and erectile dysfunction is poorly understood and thought to be multifactorial, it has been traditionally recognized that these conditions increase with age. There is increasing evidence that there is an association between cardiovascular disease and lower urinary tract symptoms as well as benign prostatic hyperplasia/benign prostatic enlargement and erectile dysfunction in elderly patients. Age might activate systemic vascular risk factors, resulting in disturbed blood flow. Hypertension, diabetes, hyperlipidemia and atherosclerosis are also linked to the etiology of lower urinary tract symptoms, benign prostatic hyperplasia/benign prostatic enlargement and erectile dysfunction. In the present review, we discuss the relationship between decreased pelvic blood flow and lower urinary tract symptoms, benign prostatic hyperplasia/benign prostatic enlargement and erectile dysfunction. Furthermore, we suggest possible common mechanisms underlining these urological conditions.

    Full Text Available Introduction. Pediatric surgeons often practice pediatric gynecology. The single-incision single-instrument (SISI technique used for appendectomy is applicable in gynecologic surgery. Methods. We retrospectively analyzed the records of patients undergoing pelvic surgery from 2008 to 2013. SISI utilized a 12 mm transumbilical trocar and an operating endoscope. The adnexa can be detorsed intracorporeally or extracorporealized via the umbilicus for lesion removal. Results. We performed 271 ovarian or paraovarian surgeries in 258 patients. In 147 (54%, the initial approach was SISI; 75 cases (51% were completed in patients aged from 1 day to 19.9 years and weighing 4.7 to 117 kg. Conversion to standard laparoscopy was due to contralateral oophoropexy, solid mass, inability to mobilize the adnexa, large mass, bleeding, adhesions, or better visualization. When SISI surgery was converted to Pfannenstiel, the principal reason was a solid mass. SISI surgery was significantly shorter than standard laparoscopy. There were no major complications and the overall cohort had an 11% minor complication rate. Conclusion. SISI adnexal surgery is safe, quick, inexpensive, and effective in pediatric patients. SISI was successful in over half the patients in whom it was attempted and offers a scarless result. If unsuccessful, the majority of cases can be completed with standard multiport laparoscopy.

    Ectopic pregnancy occurs when implantation of the blastocyst takes place in a site other than the endometrium of the uterine cavity. Uncommon implantation sites of ectopic pregnancy include the cervix, interstitial segment of the fallopian tube, scar from a prior cesarean delivery, uterine myometrium, ovary, and peritoneal cavity. Heterotopic and twin ectopic pregnancies are other rare manifestations. Ultrasonography (US) plays a central role in diagnosis of uncommon ectopic pregnancies. US features of an interstitial ectopic pregnancy include an echogenic interstitial line and abnormal bulging of the myometrial contour. A gestational sac that is located below the internal os of the cervix and that contains an embryo with a fetal heartbeat is indicative of a cervical ectopic pregnancy. In a cesarean scar ectopic pregnancy, the gestational sac is implanted in the anterior lower uterine segment at the site of the cesarean scar, with thinning of the myometrium seen anterior to the gestational sac. An intramural gestational sac implants in the uterine myometrium, separate from the uterine cavity and fallopian tubes. In an ovarian ectopic pregnancy, a gestational sac with a thick hyperechoic circumferential rim is located in or on the ovarian parenchyma. An intraperitoneal gestational sac is present in an abdominal ectopic pregnancy. Intra- and extrauterine gestational sacs are seen in a heterotopic pregnancy. Two adnexal heartbeats suggest a live twin ectopic pregnancy. Recognition of the specific US features will help radiologists diagnose these uncommon types of ectopic pregnancy.

    The case-study of genital actinomycosis in a 33-year old woman wearing a "Copper T200" IUD is presented. She was hospitalized and treated for lower abdominal pain and non-characteristic signs of adnexitis twice. Adnexectomy on the left side was performed to remove an orange-size cyst. Histo-pathological examination of a prepared tissue sample revealed a colony of Actinomyces. Following the operation the patient was treated with 3 x 500 mg Flagyl (metronidazole) 3 x 80 mg of Gentamicin im. The wound healed in 19 days after operation. This woman had worn the IUD continuously for more than 3 years, thus there was an increased risk of uterine lesions. The most frequent consequences of wearing IUDs for a long time are dysmenorrhea and endometritis and therapeutic approaches are detailed. Since its first description in the literature in 1857 actinomycosis has not been mentioned frequently. However, with the spread of IUDs, the number of actinomycosis-like cases has increased and this justifies the need for improved diagnosis. The frequency of actinomycosis occurring in women wearing IUDs ranges between 1.6% and 19.7%

    We studied the relation between prostaglandin analogue use and ocular adnexal features. We used a prospective, cross-sectional study involving 157 current, 15 past, and 171 never users of prostaglandin analogues. Patients 50 years of age or older and without conditions affecting ocular adnexal anatomy underwent glaucoma medication use history, external digital photography and systematic external adnexal exam. Two masked readers assessed the digital photos for upper lid dermatochalasis and lower lid steatoblepharon using a validated grading scheme. Another masked clinical examiner also assessed upper lid ptosis, levator muscle function, and inferior scleral show. We performed ordinal logistic regression analysis accounting for multiple covariates to assess the relation between prostaglandin analogue use and adnexal features. Multivariable analyses indicated there was a 230-fold increased risk of incremental involution of dermatochalasis (odds ratio (OR) = 2.30; 95% confidence interval (CI) 1.43-3.69; p = 5.44E-04) and a 249-fold increased risk of incremental loss of lower lid steatoblepharon (OR = 2.49; 95% CI, 1.54-4.03; p= 1.98E-04) associated with current prostaglandin analogue use (bimatoprost 0.03%, travoprost 0.005%, or latanoprost 0.004%) versus prostaglandin analogue never or past users. Upper lid ptosis (OR = 4.04; 95% CI, 2.43-6.72; p = 7.37E-08), levator dysfunction (OR = 7.51; 95% CI, 3.39-16.65; p = 6.74E-07) and lower lid retraction (OR = 2.60; 95% CI, 1.58-4.28; p = 1.72E-04) were highly associated with current prostaglandin analogue use versus prostaglandin analogue never or past users. The associations between prostaglandin analogue use and deepening of the upper lid sulci and between prostaglandin analogue use and loss of inferior periorbital fat are confirmed in this multivariable analysis.

    Full Text Available Benign paroxysmal positional vertigo (BPPV is a common clinical disorder characterized by brief recurrent spells of vertigo often brought about by certain head position changes as may occur with looking up, turning over in bed, or straightening up after bending over. It is important to understand BPPV not only because it may avert expensive and often unnecessary testing, but also because treatment is rapid, easy, and effective in >90% of cases. The diagnosis of BPPV can be made based on the history and examination. Patients usually report episodes of spinning evoked by certain movements, such as lying back or getting out of bed, turning in bed, looking up, or straightening after bending over. At present, the generally accepted recurrence rate of BPPV after successful treatment is 40%-50% at 5 years of average follow-up. There does appear to be a subset of individuals prone to multiple recurrences.

  8. CD3+ and BLA.36+ cells do not occur in the epidermis and adnexal epithelia of normal skin from the dorsolateral trunk of cats.

    A small population of resident T-lymphocytes is present in the normal epidermis of humans, mice, and rats. However, resident epidermal lymphocytes have not been reported in the normal skin of the cat. Skin-biopsy specimens from the normal skin of the dorsolateral trunk from 30 cats were examined histologically and immunohistochemically for the presence of lymphocytes, CD3+ cells, and BLA.36+ cells in epidermis and adnexal epithelia. All examinations were negative. It appears that lymphocytes occur rarely, if at all, in the epidermis and adnexal epithelial of normal cat skin. Hence, the presence of lymphocytes in these structures should be considered abnormal.

    The 6 cases reported here constitute, with 5 previously published cases, a special nosological entity tentatively called "acute benign cerebral angiopathy" by the authors. These 11 cases have in common certain radiological and clinical features. Arteriography shows segmental, multifocal and assymetrical stenoses involving the cerebral arteries between Willis' circle and the terminal arterioles and looking like "strings of sausages". The lesions disappear within one month and present the radiological characteristics of arteritis of medium caliber vessels. The clinical symptoms are suggestive of meningeal haemorrhage or acute cerebromeningeal oedema, with acute repetitive attacks of severe headache and agitation with obnubilation; epileptic seizures and transient neurological deficit may occur. True meningeal haemorrhage confirmed by lumbar puncture is seen in nearly one half of the cases; it seems to be due to alterations in the blood-brain barrier induced by the angiopathy. Intracerebral haematoma may develop, but the disease is usually benign and regresses spontaneously in a few days. None of the usual causes of cerebral arteritis (intra-cranial infection, collagen disease, allergic or toxic angitis) has been found. Pseudo-arteritis (notably spasm of ruptured arterial aneurysms) has been excluded. No aetiological factor common to the 11 cases reported has been elicited, although 6 of the patients had recently given birth and our 6 patients had benign virus infection before or during the clinical manifestations of the disease. In the authors' opinion, the most rewarding line of research would be the role of short acute attacks of arterial hypertension.

    目的 探讨不同病因引起的良性血性胸腔积液的临床特点.方法 分析我院收治的42例良性血性胸腔积液患者的临床资料.结果 42例患者中有结核性胸膜炎27例,占62.8%,其他良性疾病15例(其中肺炎旁4例,系统性红斑狼疮性3例,类风湿性关节炎2例,充血性心力衰竭2例,结节病1例,肝硬化2例,慢性胰腺炎1例),这些患者在既往史、症状及实验室检查等方面各有其特点.结论 良性血性胸腔积液以结核性胸膜炎为主,亦见于其他良性疾病,如果排除恶性肿瘤,且抗结核治疗效果欠佳,则需仔细询问患者既往史,完善有针对性的实验室检查尽早明确病因,积极治疗原发病以改善预后.%Objective To analyze the clinical characteristics of benign bloody pleural effusion from various causes. Methods Analyzed of clinical data of 42 cases with bloody pleural effusion. Results Among 42 patients, 27 cases of the bloody pleural effusion caused by tuberculous pleural effusions( 62. 8% ),15 cases caused by other benign disease( 4 cases of pneumonia, 3 cases of systemic lupus eritematosus, 2 cases of rheumatoid arthritis, 2 cases of congestive heart failure, a case of sarcoidosis, 2 cases of hepatic cirrhosis, and a case of chronic pancreatitis ). These patients' past history, simultaneous symptoms and laboratory examination results were looked at. Conclusion Most bloody pleural effusions caused by tuberculous pleuritis, also other benign diseases. When the possibilities of malignant tumors were excluded and tuberculosis treatment has poor curative effects, it is critical to enquire about the past history of patients thoroughly and to take additional related examinations in order toto determine the diagnosis early, treat properly and improve prognosis.

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

  12. Combination of signal intensity measurements of lesions in the peripheral zone of prostate with MRI and serum PSA level for differentiating benign disease from prostate cancer

    The aim of this study was to predict the benign or malignant nature of a prostatic lesion by defining a threshold value of signal intensity ratio and a limiting value of serum prostate-specific antigen (PSA) in patients with elevated PSA level. Twenty-six patients with elevated PSA level and no hypoechogenic lesions at endosonography underwent MR imaging using an endorectal body phased-array coil at 1.5 T (Siemens Magnetom Symphony). A T2-weighted turbo-spin-echo (TSE) pulse sequence was applied in a transverse orientation. Two radiologists evaluated the images. In the presence of a pathological finding they defined regions of interest (ROI) in the suspicious pathological area of the peripheral zone and in muscle for reference. The quotient of the two ROIs was calculated and then correlated with the actual PSA level. Diagnosis was confirmed by prostate biopsy. Ten of 12 patients with quotients smaller than 4 showed cancer at histology. Nine of 12 men with cancer proven by biopsy had PSA levels higher than 10 ng/ml. A significant difference (p < 0.001) was found between the quotients of cancer and quotients of chronic prostatitis, fibrosis, or glandular atrophy. The accuracy of tumor differentiation of the method was 77 %. Measurement of signal intensity quotients in the peripheral zone of the prostate in combination with knowledge of defined limits of PSA levels the technique could be helpful in detecting additional cancer areas for prostate biopsy. False-negative tumor results of standard sextant biopsy can be reduced. In men with high PSA values the method has a role in differentiating between patients who require prostate biopsy and those of clinical observation. (orig.)

    We present 2 cases of benign paroxysmal positional vertigo (BPPV) following septorhinoplasty. Benign paroxysmal positional vertigo following septorhinoplasty is an unusual entity. Two young women who had difficulty in breathing and nasal deformity underwent septorhinoplasty. On the second and the third postoperative days, the patients experienced vertigo that was induced by position changes. Both patients had neither preexisting ear disease nor vertigo before the surgery. All the examinations were normal. With Dix-Hallpike maneuver, which is the criterion-standard test, the characteristic nystagmus was observed. Right posterior canal BPPV was diagnosed, and they were both treated with Epley canalith repositioning maneuver. Publications related to postsurgical vertigo are available in literature, but it is still an underdiagnosed disorder. We would like to mention about this rare entity and inform the surgeons that they must keep in mind that a patient who is complaining about vertigo or dizziness after the surgery should be observed and investigated for BPPV.

    Full Text Available Der benigne paroxysmale Lagerungsschwindel (BPPV ist eine häufige Störung des peripheren Vestibularorgans, welche bei allen Patienten mit lageabhängigem Schwindel suspiziert werden sollte. Obwohl kurzzeitige Drehschwindelattacken als pathognomonisches Symptom gelten, weisen viele Patienten auch unsystematisierten Schwankschwindel auf, was die Diagnosestellung oft erschwert. Auslöser des BPPV sind Klziumkarbonatkristalle (Otokonien, welche sich aus der Otolithenmatrix des Utriculus lösen und in einen der drei Bogengänge gelangen. Die Diagnosestellung erfolgt mit spezifischen Provokations- bzw. Lagerungstests, um den entsprechenden Lagerungsschwindel und Nystagmus zu induzieren. Die von Semont und Epley entwickelten Befreiungsmanöver zielen darauf ab, die in den Bogengängen lokalisierten Partikel in den Utriculus zu repositionieren, wo sie keinen Drehschwindel mehr auslösen. Zur Unterscheidung des BPPV von einem zentralen Lageschwindel bzw. Nystagmus können neben der Latenz auch der Verlauf und die Dauer des Lagerungsnystagmus beitragen, von entscheidender Bedeutung in der Differentialdiagnose ist allerdings die Schlagrichtung des induzierten Nystagmus.

  15. Nihilism: a benign denial.

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

    Objective To investigate the expression of COX-2 and VEGF-C mRNA in benign and malignant breast diseases and their association with breast tumorigenesis. Methods Tissue specimens were collected from 8 cases of accessory breasts, 15 cases of adenosis, 16 cases of fibroadenoma, 11 cases of ductal carcinoma in situ (DCIS) and 40 cases of invasive ductal carcinoma (IDC). Real-time PCR was used to detect the expression of COX-2 and VEGF-C mRNA. Results The accessory breasts were all negative for COX-2 mRNA expression, and weakly expressed VEGF-C. The expression of COX-2 and VEGF-C mRNA were increased significantly in adenosis and fibroadenoma tissues (P<0.05). In DCIS and IDC the expressions of COX-2 and VEGF-C mRNA were higher than those in adenosis and fibroadenoma (P < 0. 05). In IDC the expressions of COX-2 and VEGF-C mRNA were correlated with the histological grades. In DCIS and IDC, there was a strong positive correlation between COX-2 and VEGF-C mRNA expression (r = 0.82, P=0.002;r = 0. 89,P= 0.000, respectively). Conclusion The expressions of COX-2 and VEGF-C genes are increased in both benign and malignant breast diseases, and the expression levels in malignant breast diseases are higher than those in benign diseases. These results suggest that they might be important factors in the breast tumorigenesis, especially in breast carcinogenesis and tumor development.%目的 研究COX-2和VEGF-C mRNA在乳腺良恶性病变中的表达情况,探讨两者在乳腺肿瘤发生过程中的相互关系.方法 运用Real-time PCR方法对90例乳腺良恶性病变组织中COX-2和VEGF-C mRNA的表达进行检测.结果 8例副乳腺组织中,COX-2和VEGF-C mRNA不表达或低表达,15例腺病和16例纤维腺瘤中两者表达明显增加(P<0.05),11例DCIS中,两者均高表达,高于腺病和纤维腺瘤(P<0.05),40例IDC中,两者同样高表达,并且肿瘤级别越高,表达水平越高.在DCIS和IDC中,两者表达存在正相关关系(分别r=0.82,P=0.002;r=0

    The greater omentum is the largest peritoneal fold and can be the origin of primary pathologic conditions, as well as a boundary and conduit for disease processes. Most diseases involving the omentum manifest with nonspecific and overlapping features on computed tomography (CT). In particular, varying benign disease processes of traumatic, inflammatory, vascular, or systemic origin can occur in the omentum during the follow-up period after surgery for intra-abdominal malignancy. It can be challenging for radiologists due to various spectrum of CT findings. Thus, we reviewed the CT findings of various benign omental lesions after surgery for intra-abdominal malignancy.

    Purpose: To evaluate the natural history, behavior of progression, prognostic factors, and treatment-related adverse effects of primary ocular adnexal mucosa-associated lymphoid tissue (MALT) lymphoma (POAML). Methods and Materials: Eighty-six patients with histologically proven stage I POAML treated with radiation therapy at National Cancer Center Hospital, Tokyo between 1990 and 2010 were retrospectively reviewed. The median age was 56 years (range, 18-85 years). The median dose administered was 30 Gy (range, 30-46 Gy). Seventy-seven patients (90%) were treated by radiation therapy alone. Results: The median follow-up duration was 9 years (range, 0.9-22 years). The 5- and 10-year overall survival (OS) rates were 97.6% and 93.5%, respectively, and no patients died of lymphoma. Patients with tumor sizes ≥4 cm showed a greater risk of contralateral relapse (P=.012). Six patients with contralateral relapse were seen and treated by radiation therapy alone, and all the lesions were controlled well, with follow-up times of 3 to 12 years. There was 1 case of local relapse after radiation therapy alone, and 3 cases of relapse occurred in a distant site. Cataracts developed in 36 of the 65 eyes treated without lens shielding and in 12 of the 39 patients with lens shielding (P=.037). Conclusions: The majority of patients with POAML showed behavior consistent with that of localized, indolent diseases. Thirty gray of local irradiation seems to be quite effective. The initial bilateral involvement and contralateral orbital relapses can be also controlled with radiation therapy alone. Lens shielding reduces the risk of cataract.

    Purpose: To evaluate the long-term treatment outcome and disease behavior of primary ocular adnexal MALT (mucosa-associated lymphoid tissue) lymphoma (POAML) after treatment with radiotherapy. Methods and Materials: Seventy-eight patients (42 male, 36 female) diagnosed with stage I POAML between 1991 and 2010 at Kobe University Hospital were included. The median age was 60 years (range, 22-85 years). The median radiation dose administered was 30.6 Gy. Rituximab-based targeted therapy and/or chemotherapy was performed in 20 patients (25.6%). Local control (LC), recurrence-free survival (RFS), and overall survival (OS) rates were calculated using the Kaplan-Meier method. Results: The median follow-up duration was 66 months. Major tumor sites were conjunctiva in 37 patients (47.4%), orbita in 29 (37.2%), and lacrimal glands in 12 (15.4%). The 5- and 10-year OS rates were 98.1% and 95.3%, respectively. The 5- and 10-year LC rates were both 100%, and the 5- and 10-year RFS rates were 88.5% and 75.9%, respectively. Patients treated with a combination of radiotherapy and targeted therapy and/or chemotherapy had a trend for a better RFS compared with those treated with radiotherapy alone (p = 0.114). None developed greater than Grade 2 acute morbidity. There were 14 patients who experienced Grade 2 morbidities (cataract: 14; retinal disorders: 7; dry eye: 3), 23 patients who had Grade 3 morbidities (cataract: 23; dry eye: 1), and 1 patient who had Grade 4 glaucoma. Conclusions: Radiotherapy for POAML was shown to be highly effective and safe for LC and OS on the basis of long-term observation. The absence of systemic relapse in patients with combined-modality treatment suggests that lower doses of radiation combined with targeted therapy may be worth further study.

    2014-08-01

    Pigmented extramammary Paget's disease (PEMPD) is an uncommon intraepithelial adenocarcinoma and a rare variant of Paget's disease affecting skin that is rich in apocrine sweat glands such as the axilla, perianal region and vulva. It most commonly occurs in postmenopausal women and presents as a superficial pigmented scaly macule, mimicking a melanocytic lesion. The histological presentation is adenocarcinoma in situ with an increased number of melanocytes scattered between the Paget's cells. Therefore, PEMPD may be misdiagnosed as a melanocytic tumour both clinically and histologically. The tumour cells are usually positive for cytokeratin 7, epithelial membrane antigen, Cam 5.2, HER2, and mucicarmine stain while S100 and human melanoma black-45 highlight the processes of reactive dendritic cells. The association between Paget's cells and intratumoural reactive melanocytes is still unclear. We report our first case of PEMPD associated with an intradermal naevus involving the axilla in a 63-year-old woman.

    Conclusions: We interpret the elevated thyroid vascularization and low magnesium levels as signs of an inflammatory process related to the musculoskeletal changes. Improvement of thyroid function and morphology can be achieved after correcting the influence of stressors together with the supplementation regime. We hypothesize that the central biochemical event in thyroid disease is that of an acquired, altered mitochondrial function due to deficiency of magnesium, selenium, and coenzyme Q10.

    The recognition of asbestos-related diseases of the lung and/or pleura as an occupational disease is of psychosocial, medical and legal importance to the insured person. Radiological imaging is an essential part of the assessment and requires an increasingly high level of competence in the field of radiological diagnosis of pneumoconiosis in interdisciplinary collaboration with occupational medicine and pneumonology. The chest radiogram remains an integral part of basic diagnostic procedures in asbestos-related diseases of the lungs and/or pleura. Its importance lies in the detection of extended pleural changes as well as substantial fibrosis. The inherent low sensitivity and specificity of projection radiography is taken into account by the increasing use of multi-slice high resolution (HR) CT (in low dose technique). Radiological pitfalls in pleural plaque assessment with respect to plain chest X-ray concern all structures that superimpose on the pleural circumference, particularly the anatomical layers of the chest wall (extra-pleural fatty tissue, muscles, thoracic skeleton) as well as other pulmonary findings that can only be reliably assigned using CT. Even if state-of the-art CT is applied, asymmetries and abnormal expression of anatomical structures and variants (e.g. muscles and blood vessels) can lead to false-positive findings. The interstitial fibrosis of asbestosis, manifested as usual interstitial pneumonia (UIP) is non-pathognomonic for asbestosis. Therefore, parietal pleural thickening as a coincident finding to UIP is considered as being the main feature and a highly suggestive indicator of asbestosis in patients with a history of asbestos exposure.

    Objectives The current study aims to summarize breast anthropomorphic measurement features in Chinese patients with breast diseases and to investigate their potential correlations with demographic factors. Materials and methods Fifteen breast anthropomorphic parameters of 605 Chinese female patients were collected prospectively. Breast ptosis status was scaled by two methods and breast volume was calculated according to a modified formula of BREAST-V. Results Among 1210 breasts, the average breast volume was 340.0±109.1 ml (91.8–919.2 ml). The distance from the nipple to the inframammary fold was 7.5±1.6 cm in the standing position. The width of the breast base was 14.3±1.4 cm (8.5–23.5 cm). The incidence of breast ptosis was 22.8% (274/1204), of which 37 (23.5%) and 79 (31.7%) women had severe ptosis assessed by different criteria. Increased height (OR[odds ratio] = 1.500, Pcosmetic and reconstructive breast surgery decisions. Post-menopausal status, increased BMI, and breastfeeding for more than six months were independent risk factors for both increased breast volume and breast ptosis. PMID:28192525

    2006-07-07

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

    Multicystic benign mesothelioma (MBM) is a rare peritoneal pathology typically affecting women in reproductive age. Though MBM is considered benign, these lesions are prone to recurrence and their growth could be modulated by the presence of oestrogen receptors. Acute presentation of MBM is still very rare in pregnancy and management options are not established. We describe a case of MBM presenting in early pregnancy with acute pain. This was successfully treated with surgical resection. Pregnancy continued uneventfully to term and no evidence of recurrent MBM was found at Caesarean section.

    Full Text Available Hysterectomy is the commonest gynecologic operation performed not only for malignant disease but also for many benign conditions such as fibroids, endometrial hyperplasia, adenomyosis, uterine prolapse, dysfunctional uterine bleeding, and cervical intraepithelial neoplasia. There are many approaches to hysterectomy for benign disease: abdominal hysterectomy, vaginal hysterectomy, laparoscopic assisted vaginal hysterectomy (LAVH where a vaginal hysterectomy is assisted by laparoscopic procedures that do not include uterine artery ligation, total laparoscopic hysterectomy (TLH where the laparoscopic procedures include uterine artery ligation, and subtotal laparoscopic hysterectomy (STLH where there is no vaginal component and the uterine body is removed using a morcelator. In the last decades, many new techniques, alternative to hysterectomy with conservation of the uterus have been developed. They use modern technologies and their results are promising and in many cases comparable with hysterectomy. This paper is a review of all the existing hysterectomy techniques and the alternative methods for benign indications.

    Benign recurrent aseptic meningitis (BRAM) or Mollaret's meningitis is a rare disease characterized by recurrent episodes of aseptic meningitis followed by spontaneous recovery. Disease courses over several years have been reported. In most cases, BRAM is caused by HSV-2, less frequently by other viruses or autoimmune diseases. In up to 10 %, the aetiology remains unclear. We present a case of idiopathic BRAM and discuss clinical findings, diagnosis and therapeutic options of this rare illness.

    Objective:To analyze the clinical characteristics of benign paroxysmal positional vertigo (BPPV) secondary to otogenic diseases. Methods: The clinical data of 67 patients with otogenic BPPV admitted to department of otolaryngology in Third People's Hospital of Yancheng City from January 2010 to June 2012 was retrospectively analyzed. The outcome of patients with otogenic BPPV was compared with the idiopathic BPPV. All of the patients were treated with the canalith repositioning procedure (CRP). Results: Among the 67 patients, 22 cases were secondary to sudden deafness, 17 cases were secondary to labyrinthitis, 13 cases were secondary to Meniere's disease, 8 cases were secondary to operations on the middle or inner ear, and 7 cases were secondary to vestibular neuronitis. There were no statistical difference in age, gender, lesion location in semicircular canal between otogenic BPPV patients and idiopathic BPPV patients (P>0. 05). The patients secondary to sudden deafness were significantly older than idiopathic BPPV patients (P<0. 001), while CRP times of BPPV patients secondary to Meniere's disease was significantly more than that of idiopathic BPPV patients (P = 0. 003). Conclusions: The causes of otogenic BPPV is diverse, and prognosis of the otogenic BPPV is associated with the causes.%目的:探讨继发于耳源性疾病的良性阵发性位置性眩晕(benign paroxysmal positional vertigo,BPPV)的临床特征.方法:回顾分析盐城市第三人民医院耳鼻咽喉科2010年1月 2012年6月收治的67例继发于耳源性疾病的BPPV(耳源性BPPV)患者的临床资料,并与同期119例原发性BPPV患者对照比较,分析耳源性BPPV的临床特点、病因及预后.所有患者均采用管石复位法治疗.结果:耳源性BPPV患者中包括突发性耳聋22例(32.8%),迷路炎17例(25.4%),梅尼埃病13例(19.4%),中-内耳手术后8例(11.9%),前庭神经元炎7例(10.4%).耳源性BPPV与原发性BPPV两组患者年龄、性别、半

    Full Text Available Background: Benign tremulous parkinsonism (BTP is a tremor dominant syndrome characterized by mild, levodopa-resistant parkinsonism with limited disability or progression. Case Presentation: A 56-year-old woman presented with a 2-year history of tremor. Neurological examination revealed right-hand rest tremor and slow finger tapping with decreased amplitude; however, we did not observe posture tremor, rigidity, bradykinesia, or posture disability. She was diagnosed with Parkinson's disease (PD and received levodopa/carbidopa, effectively treating her rest tremor. At the age of 61 years, reoccurrence of the rest tremor was successfully treated again with levodopa/carbidopa and selegiline. Approximately 11 years have passed since symptom onset and the patient shows no further disease progression. Conclusion: This case broadens the characterization of BTP to include levodopa-responsive PD.

    2015-12-01

    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

    Benign goitres have the potential to reach massive sizes if neglected, but most have a protracted course that may or may not present with compressive symptoms. We report the case of a 57-year-old man who presented with a rapidly enlarging nodular goitre resulting in acute respiratory failure. Endotracheal intubation and emergency total thyroidectomy were performed, revealing massive thyroid nodules with minimal intrathoracic extension and tracheal erosion. Despite a course and clinical findings suggestive of malignant disease, histopathology was consistent with a benign multinodular goitre. Several cases of benign goitres necessitating endotracheal intubation have been reported. Airway compromise was attributed to a significant intrathoracic component, or inciting events such as thyroid haemorrhage, pregnancy, radioiodine uptake or major surgery. Obstructive symptoms may not correlate well with objective measures of upper airway obstruction such as radiographs or flow volume loops.

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

    Full Text Available We aimed to evaluate the diagnostic accuracy of serum D-dimer levels in pregnant women with adnexal torsion (AT. The pregnant women with ovarian cysts who suffered from pelvic pain were divided into two groups; the first group consisted of the cases with surgically proven as AT (n = 17 and the second group consisted of the cases whose pain were resolved in the course of follow-up period without required surgery (n = 34. The clinical characteristics and serum D-dimer levels were compared between the groups. Patients with AT had a higher rate of elevated serum white blood cell (WBC count (57% vs. 16%, p = 0.04 and serum D-dimer levels (77% vs. 21%, p < 0.01 on admission in the study group than in the control group. Elevated D-dimer and cyst diameter larger than 5 cm yielded highest sensitivity (82% for each; whereas the presence of nausea and vomiting and elevated CRP had the highest specificity (85% and 88%, respectively. This is the first study that evaluates the serum D-dimer levels in humans in the diagnosis of AT, and our findings supported the use of D-dimer for the early diagnosis of AT in pregnant women.

    Benign prostatic hyperplasia (BPH) represents an important public health problem in ageing men due to frequently associated lower urinary tract symptoms (LUTS), which may impair quality of life. BPH is also a progressive disease, mainly characterized by a worsening of LUTS over time, and in some patients by the occurrence of serious outcomes such as acute urinary retention and need for BPH-related surgery. The management of BPH and LUTS in men should move forward its focus on symptom control only. Indeed, the goals of therapy for BPH are not only to improve bothersome LUTS but also to identify those patients at risk of unfavourable outcomes in order to optimize their management and reduce complications. Risk stratification and tailored treatment should improve the reductions in both symptoms and the long-term consequences of BPH and BPH treatments. To do this, clinicians need to know possible factors that may support the develop of PBH and possible risks due to the BPH itself.

Foram apresentados resultados das possíveis relações entre variáveis reprodutivas e o risco para DBM. Os casos e controles foram comparados levando em conta a idade na menarca e na menopausa, o número de gravidezes, de meses em que amamentaram e de ciclos menstruais ovulatórios, e os antecedentes familiares de câncer de mama. Mostraram influência significativa, em relação às DBM, a nuliparidade, aumentando o risco enquanto a idade de 30 ou mais anos no primeiro parto o reduziu; o número de ciclos ovulatórios, que foi significativamente maior para os casos, e a média de meses de uso de pílula, menor entre as mulheres com DBM. O uso de contraceptivos orais apresentou um efeito protetor apenas quando a duração total do uso foi maior que dois anos. Os resultados não se revelaram novos ou diferentes se comparados com outros estudos, mas confirmam a relativa concordância entre os fatores de risco para DBM e para câncer de mama, ainda que as relações entre esses fatores e as DBM não sejam tão claras como o são para o câncer, e existam também algumas discrepâncias.The purpose of the study was the identification of risk factors for benign breast diseases (BBD; 257 women with BBD diagnosed through pathological anatomy or citology and a matched control for each were studied. Subjects were selected at The State University of Campinas Hospital and at a private clinic. To enter the study cases had to have a first diagnosis of BBD between October 1979 and August 1984. The following BBD were considered: dysplasia, fibroadenoma, cystic disease, papilloma and ductal ectasia. Reproductive variables were studied as risk factors, including menstrual ovulatory cycles. The date on which the BBD was diagnosed was defined as the index date. For controls, data were considered up to when

    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.

    2015-01-01

    Full Text Available Benign prostatic hypertrophy (BPH has become a major global health problem both in its frequency by which it determines the complications and the problems of diagnosis and treatment it requires. BPH is a heterogeneous disease. The symptoms attributed to BPH may have other coexisting causes and growth factors both androgen-dependent and independent, which promotes prostate enlargement. It is well known that prostate size correlates poorly with the symptoms so that reducing prostate using 5-alphareductase or alphablocants inhibitors may not always be sufficient. A better understanding of the pathophysiology of BPH and its interactions with other drugs will help the development of new substances with a better efficiency. This present work aims to be a modest contribution related to medical treatment in benign prostatic hyperplasia and the role that the generalist practitioner should play in managing of this urinary disease quite common in elderly men.

  13. Revised criteria for suspicion of non-benign positional vertigo.

    2013-04-01

    Benign paroxysmal positional vertigo (BPPV) is the most commonly diagnosed vestibular vertigo. BPPV can be diagnosed by clinical examination and its treatment is based on particle repositioning manoeuvres, and specialized equipment is not required. Therefore, most patients could be diagnosed and treated by their general practitioner. Unfortunately, not all positional vertigos are benign. Symptoms similar to those of BPPV can be caused by diseases that affect the central nervous system. It must be possible to define criteria that allow us to suspect, in a patient with symptoms of positional vertigo, the possibility of a cerebral origin ('non-benign PV'). Requests for magnetic resonance imaging must be justified by the fulfillment of these criteria. That is especially relevant in primary care, because these criteria should make possible to distinguish between patients with positional vertigo that could be treated by general practitioner and patients that need to be directed to especialized units. We propose the following revised criteria for suspected non-benign PV: (i) association with signs or symptoms of neurological disorder, (ii) nystagmus without dizziness in positional diagnostic tests, (iii) atypical nystagmus direction, (iv) poor response to therapeutic manoeuvres and (v) recurrence (confirmed by positional tests) on at least three occasions.

  14. Benign communicating hydrocephalus in children

    Kendall, B.; Holland, I.

    1981-03-01

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

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

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

    The present study was to find out through histopathological records the most frequently occurring disease of the prostate from suspected prostate diseases in Calabar, Cross River State, Nigeria. A total number of 324 cases of prostatic biopsies and autopsy materials recorded in the histopathology laboratory of the University of Calabar Teaching Hospital (UCTH), Calabar between 1986 and 1995 were used for this study. Benign prostatic hypertrophy was observed as the major pathology among all the diseases of the prostate gland recorded in UCTH in Calabar having accounted for 76.3% (261 out of 342) while prostatic carcinoma accounted for 19% (65 out of 324), rest 4.7% (16 out of 342) were inflammatory lesions. The result indicated that benign prostatic hypertrophy occurs in men from 40 years and above. The frequency increased with age, reaching a maximum of 34.5% (90 out of 261) in the age group (70-79) years old. The people in Cross River State should be informed of the high frequency of benign prostatic hypertrophy and should be advised to seek health care promptly in suspected prostate related illness.

    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.

    {sup 18}F-fluorodeoxyglucose positron emission computed tomography (FDG PET-CT) is widely used in the initial staging and response evaluation of patients with malignancy. This review describes a spectrum of benign breast findings incidentally detected by FDG PET-CT at staging that may be misinterpreted as malignancy. We describe the pattern of distribution and intensity of FDG uptake in a spectrum of benign breast diseases with their corresponding typical morphological imaging characteristics to help the nuclear medicine physician and/or general radiologist identify benign lesions, avoiding unnecessary breast imaging work-up and biopsies.

    Pelvic and peritoneal tuberculosis may resemble advanced ovarian cancer due to the presence of ascites, complex adnexal masses, peritoneal deposits and raised CA-125 level, especially in peri- and postmenopausal women. Other common features among women with these two conditions are abdominal pain and distension, weight loss and reduced appetite. As the treatment of pelvic-peritoneal tuberculosis is completely different from that of ovarian cancer, it is important to reach a correct diagnosis. Sometimes women with pelvic-peritoneal tuberculosis may be subjected to a laparotomy for suspected ovarian cancer which is likely to increase their morbidity. In the present article, we report ten women in the peri- and post-menopausal age group where this diagnostic dilemma arose of whom seven were diagnosed only after a laparotomy had been performed for suspected ovarian cancer due to adnexal masses with ascites and raised CA-125 level. Ascitic fluid showing lymphocytic predominance, raised ADA level and absence of malignant cells are pointers to consider the possibility of pelvic- peritoneal tuberculosis, especially in endemic countries like India. In such situations, an effort should be made to obtain a cytological or histopathological diagnosis of either condition by ultrasound guided needle biopsy or laparoscopically obtained biopsy rather that proceeding with laparotomy for suspected ovarian cancer.

    2005-06-01

    Full Text Available Epiphyseal extension of benign pathology is regarded as an infrequent occurrence. This observation has been attributed to anatomical and biochemical phenomenon unique to physeal cartilage. We report a retrospective series of six patients over a period of 4 years, diagnosed with benign pathologies that showed crossing of an open physeal plate by the disease. Four of these cases were infections and two were benign tumors. The patients were aged between 5 and 11 years, all of them were treated at a tertiary referral centre and followed up for a minimum period of 6 months to evaluate the progress of disease. The findings are more than just a pathological curiosity as they alter the management and surgical procedure that needs to be performed for these conditions. The recognition of the fact that benign tumors may occasionally present with transphyseal spread will prevent unjustified radical procedures that are best reserved for aggressive malignant conditions.

    Evidence from certain geographical areas links lymphomas of the ocular adnexa marginal zone B-cell lymphomas (OAMZL) with Chlamydophila psittaci (Cp) infection, suggesting that lymphoma development is dependent upon chronic stimulation by persistent infections. Notwithstanding that, the actual immunopathogenetical mechanisms have not yet been elucidated. As in other B-cell lymphomas, insight into this issue, especially with regard to potential selecting ligands, could be provided by analysis of the immunoglobulin (IG) receptors of the malignant clones. To this end, we studied the molecular features of IGs in 44 patients with OAMZL (40% Cp-positive), identifying features suggestive of a pathogenic mechanism of autoreactivity. Herein, we show that lymphoma cells express a distinctive IG repertoire, with electropositive antigen (Ag)-binding sites, reminiscent of autoantibodies (auto-Abs) recognizing DNA. Additionally, five (11%) cases of OAMZL expressed IGs homologous with autoreactive Abs or IGs of patients with chronic lymphocytic leukemia, a disease known for the expression of autoreactive IGs by neoplastic cells. In contrast, no similarity with known anti-Chlamydophila Abs was found. Taken together, these results strongly indicate that OAMZL may originate from B cells selected for their capability to bind Ags and, in particular, auto-Ags. In OAMZL associated with Cp infection, the pathogen likely acts indirectly on the malignant B cells, promoting the development of an inflammatory milieu, where auto-Ags could be exposed and presented, driving proliferation and expansion of self-reactive B cells.

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

  5. Benign Paroxysmal Positional Vertigo: An Integrated Perspective

    2014-01-01

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

    There is no detailed information about benign asbestos pleural effusion (BAPE). The aim of the study was to clarify the clinical features of BAPE. The criteria of enrolled patients were as follows: (1) history of asbestos exposure; (2) presence of pleural effusion determined by chest X-ray, CT, and thoracentesis; and (3) the absence of other causes of effusion. Clinical information was retrospectively analysed and the radiological images were reviewed. There were 110 BAPE patients between 1991 and 2012. All were males and the median age at diagnosis was 74 years. The median duration of asbestos exposure and period of latency for disease onset of BAPE were 31 and 48 years, respectively. Mean values of hyaluronic acid, adenosine deaminase, and carcinoembryonic antigen in the pleural fluid were 39,840 ng/mL, 23.9 IU/L, and 1.8 ng/mL, respectively. Pleural plaques were detected in 98 cases (89.1%). Asbestosis was present in 6 (5.5%) cases, rounded atelectasis was detected in 41 (37.3%) cases, and diffuse pleural thickening (DPT) was detected in 30 (27.3%) cases. One case developed lung cancer (LC) before and after BAPE. None of the cases developed malignant pleural mesothelioma (MPM) during the follow-up.

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

    Full Text Available Benign intracranial hypotension, otherwise called as idiopathic intracranial hypotension is caused by CSF leaks due to disruption in spinal meninges. It is most commonly caused by disruption and leak at cervical and thoracic spine. Imaging is sometimes the most important key to the diagnosis of idiopathic intracranial hypotension, which helps in appropriate treatment of the patient. Here, we are presenting a case of benign intracranial hypotension associated with incidental parasagittal meningioma. The presence of benign intracranial hypotension was confirmed by taking MR myelogram.

    Objective To explore the clinical characteristics of the benign paroxysmal positional vertigo (BPPV) associated with Meniere's disease (MD) in retrospect in an effort to improve the diagnosis and efficacy of treatment Method Fifteen cases (1 male and 14 female, aged 46 to 68 years old) of BPPV associated with MD from July 2007 to June 2009 were retrospectively analyzed. Patient clinically characterized with positional paroxysmal vertigo were diagnosed as MD by ECochG and glycerol test and were confirmed as BPPV associated with MD by Dix Hallpike test or roll test They were treated with Epley maneuver or Barbecue rol maneuver according to the type of BPPV, and the efficacy was evaluated. Result (1) Most cases involved female patients in this study; (2) BPPV occurred after MD in al of the cases, of which 13 cases were posterior semicircular canal lithiasis (9 cases in the same ear, 2 in the other and 2 in both) and 2 cases were horizontal semicircula canal lithiasis (cupula lithiasis in the same ear) ; (3) in this study, 10 patients were cured after 3-4 times of posture treatment (66.7% ), 4 patients were cured after 5 times and 1 patient received endolymphatic sac decompression because of recurrent vertigo. Conclusion (1) BPPV can result from MD, for which a possible mechanism may be the hydrolabyrinth that lead to eardust falling off. (2) Most cases of BPPV occurred in the posterior semicircular canal in the same ear. Most cases in incidence rate have obvious sexual bias in female. (3) Eardust reposition is an effective treatment for BPPV caused by MD; while it is refractory compared to ordinary BPPV and requiremultiple treatments, which may be related to the recurrence of hydrolabyrinth.%目的 回顾性分析继发于梅尼埃病(MD)的良性阵发性位置性眩晕(BPPV)的临床特点,并探讨该病的诊断与治疗特点.方法 自2007年7月至2009年6月于中山大学附属第三医院入院的梅尼埃病伴BPPV患者15例,男1例,女14例;年龄46~69

  11. Horizontal Canal Benign Positional Vertigo

    1998-03-01

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

El estudio mediante Tomografía Axial Computerizada apreció un exceso de deposito graso de distribución homogénea no encapsulado (difuso sobre los hombros, mamas y cintura abdominal, sin afectación de estructuras profundas. Consideramos importante conocer los dos tipos existentes de Lipomatosis Simétrica Benigna, por sus diferencias tanto en la localización de las masas lipomatosas como en la afectación de estructuras profundas. Es por ello que aportamos este caso de Lipomatosis Simétrica Benigna tipo II sin afectación cervical ni de estructuras profundas.We report the case of a 56 years-old man with a 35-years history of alcohol abuse, but no other illness. The patient presented masses on shoulders, breasts and flanks that had enlarged progressively over the previous two and a half years, and that hindered his work by restricting mobility. Computed Tomography revealed non-encapsulated excess fat deposits evenlydistributed on shoulders, breasts and abdomen, without affecting the deep structures. Awareness of the two types of Benign symmetric lipomatosis is necessary because of their differences, both in location of the lipomatous masses and in the involvement of the deep structures. We therefore report this case of type II Benign symmetric lipomatosis without cervical or deep structure involvement.

    This study described the imaging features of a distinctive pattern of biopsy-proven benign non-traumatic vertebral collapse (VC) that can mimic malignancy. Among 240 patients referred with painful VC over a 10-year period, we retrospectively selected 15 cases of benign VC which simulated malignancy, due to cortical bone destruction on radiographs. The diagnosis of benign origin was documented by percutaneous biopsy and 12-months of follow-up. Radiographs, CT and MR images of the spine were reviewed. Findings suggestive of malignancy included destruction involving the anterolateral cortex, posterior cortex and pedicles of the vertebral body (46%,15% and 15% respectively) at CT, epidural soft-tissue masses on CT (23%) and MR images (21%), and diffuse low signal-intensity (SI) of the vertebral body (50%) and pedicles (79%) on T1-weighted images. Features suggestive of a benign origin included an intravertebral vacuum phenomenon on radiographs and CT (13%), fracture lines within the vertebral body (92%) or pedicles (62%) at CT and presence an intravertebral area of high SI on T2-weighted images (93%). Benign non-traumatic osteolytic VC can simulate malignancy on radiographs. The features, above mentioned on CT and MR suggestive of a benign VC, are useful in interpreting biopsy results of such lesions and avoiding unnecessary repeat biopsy. (orig.)

    Benign prostatic hyperplasia (BPH) the most common condition in aging men is the non malignant enlargement of the prostate gland with increase in numbers of both epithelial and stromal cells within the periurethal transition zone of the prostate. Sources of symptoms in patient with BPH appear to be both static and dynamic component. Management of BPH has undergone a rapid evolution over the past decade to aid men with lower urinary tract symptoms attributed to bladder outlet obstruction. Treatment of clinical BPH aims to improve symptoms, prevent urinary tract infections, avoid renal insult, relief obstruction and improve bladder emptying.Prostate cancer patients and those with benign prostatic hyperplasia are increasingly exploring the use of plant derived non-nutritive compounds with protective or disease preventive properties, especially due to long term side effects of pharmacological treatment and risk of mortality associated with surgical procedures. Phytotherapeutic preparations are plant extracts with different components obtained by different extraction procedures. Numerous mechanisms of action have been postulated for mono and combination plant extracts. This article give a brief account of rationale and efficacy of various existing phytotherapeutic agents in the management of benign prostatic hyperplasia, including the herbs which hold the potential promise are also mentioned , although much research is still required.

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

    Full Text Available Benign multicystic mesothelioma (BMCM is a rare tumor of the abdomen-peritoneum of unknown etiology. This benign tumor was initially described by Plaut in 1928 when he observed loose cysts in the pelvis during a surgery for a uterine leiomyoma.2 The mesothelial origin was later confirmed by electron micro-scopy by Mennemeyer and Smith in 1979.3 To date, there are approximately 140 cases of BMCM reported in the literature.4 This disease primarily occurs in pre-menopausal women and is associated with a history of pelvic inflammatory disease, prior abdominal surgery, and endometriosis.4,5 The pathogenesis of this disease remains controversial, with possible etiologies including a neoplastic versus a reactive process.5 In the literature, a few case reports discuss a possible genetic or familial association with BMCM.6 Specifically, one report describes a man with familial Mediterranean fever who developed BMCM. Although familial Mediter-ranean fever is associated with malignant mesothelioma, he had only BMCM, and did not suffer from malignant mesothelioma.6 A genetic evaluation and chromosomal analysis were not able to identify a specific genetic cause of the family’s pattern of disease. This case report describes two female siblings diagnosed with BMCM. In addition, a third sister also had findings consistent with BMCM, however, the discrete histological diagnosis was never confirmed.

    The patogenesis and etiology of acute ataxia in childhood is not well known. It may occur without previous symptoms or may be the expression of specific infectious diseases. Forty patients hospitalized at the Hospital de Niños de Buenos Aires en 1972-1978, were studied. The neurological manifestations showed an acute onset, being ataxia the main sign, associate to tremor, nystagmus, dysartria, oculo-motor paresia, muscular weakness, and hyporeflexia. Most of the patients (82%) became cured within the first four weeks. It is advisable to establish a follow-up with periodic controls, mainly in those patients in whom an association with previous infectious diseases did not exist to be able to detect an association with degenerative or desmyelinizing diseases.

    Objective: To determine the diagnostic yield of prostate specific membrane antigen ( PSMA) for the diagnosis of benign or malignant prostate diseases. Methods: The relative expression of serum PSMA was assayed in patients with prostate carcinoma ( group PCa, n = 63) , benign prostate hypertrophy ( group BPH, n = 99) and healthy controls (control group, n = 33) by using real-time quantitative polymerase chain reaction for further determination of the between-group difference. Results: The between-group difference in PSMA reached statistical significance ( all P 0. 05). Conclusion; The PSMA in peripheral blood as determined by real-time quantitative PCR may help differentiate prostate carcinoma and benign prostate hypertrophy but could serve as an adjuvant or complementary approach owing to the limited significance for differentiation between patients with prostate diseases and normal controls.%目的:探讨前列腺特异性膜抗原(PSMA)对于前列腺良恶性疾病的诊断价值.方法:采用实时荧光定量PCR方法检测前列腺癌患者(前列腺癌组,63例)、良性前列腺增生患者(良性前列腺增生组,99例)及健康者(正常对照组,33例)血液中PSMA的相对表达量,并分析3组之间的差异.结果:3组间PSMA相对表达量存在差异(P<0.05),良性前列腺增生组、前列腺癌组均低于正常组(P<0.05),前列腺癌组高于良性前列腺增生组(P<0.05),良性前列腺增生组、前列腺癌组PSMA相对表达量与血清总前列腺特异性抗原TPSA不具相关性(P>0.05).结论:实时荧光定量PCR检测外周血PSMA可用于区分前列腺癌与良性前列腺增生,但单纯检测外周血PSMA尚无法准确区分出前列腺疾病与健康对照人群,仅可作为一种辅助和补充检测手段.

    Full Text Available Benign joint hypermobility syndrome (BJHS was earlier considered as a mild or trivial entity, but nowadays it is reported as a multisystem hereditary connective tissue disorder with serious morbidities. In fact, the term ‘Benign’ has been removed, renaming the disease as ‘Joint Hypermobility Syndrome’ (JHS. In addition to the well-known musculoskeletal consequences of joint pain and instability, it can cause chronic widespread pain, gastrointestinal dysmotility, anxiety, phobic states and dysautonomia. We present here the case of a 53-year-old lady who presented with history of irritable bowel syndrome, elbow dislocation, repeated knee injuries, and instability resulting in severe secondary osteoarthritis (OA.

    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.

    Full Text Available INTRODUCTION: Open biopsy is widely considered to be the procedure of choice for diagnostic tissue sampling of bone tumors. However, associated disadvantages include in - patient procedure requiring hospitalization, risk of infection, hematoma formation and pathological fractures. As an alternative FNA cytology is increasingly used as a diagnostic modality. It is a challenging technique due to difficulties in approaching bone lesions and obtaining adequate material. AIMS: 1. To study the prevalence and distribution of various breast lesions in women of various age groups. 2. To classify the smears into C1 - C5 category . 3. To enumerate the difficulties encountered in this study. 4. To emphasize the role of FNAC in diagnostic workup in breast lesions. MATERIALS AND METHODS: FNAC was done on 208 cases of breast lesions from September 2011 to July 2012 in department of Pathology, Bowring hospital, BMC&RI, Bangalore. Cases presenting to the OPD with b r east lumps were subjected for FNAC. Aspirations were carried out with 10ml disposable syringe with a 22guage needle, materi al was obtained. Aspirates were smeared and few of them were immediately fixed with methanol and stained with H&E, rest of the smears were air dried for MGG staining. The diagnostic criteria C1 - C5 as recommended by NHS breast screening program has been inc orporated for reporting the slides along with pathological diagnosis wherever possible. RESULTS : 1. In countries with limited resources like India, FNAC may be used as the first line of diagnostic tool for evaluating breast lesions. 2. Breast FNA continues its monopoly over core biopsy and open excision biopsy. Benign conditions of breast can be diagnosed easily on FNA if done accurately. The current usage of C1 - C5 categories in typing the breast lesions gives a wide scope for pathologist to place the doubt ful lesions freely in the categories. However a disease specific diagnosis was preferred by the clinicians. 3. In

    Full Text Available Fasciculations are characterized by visible subtle and fast contractions of muscle, even wormlike in movement, by the contraction of a fascicle of muscle fibers. The authors present the case study of a 28-year-old patient with the appearance of migratory and diffuse fasciculations with an onset after partial tapering off of oral corticosteroides (60 mg total dose indicated for treatment of Minimal change Glomerulopathy. Clinical Neurological physical exam allied with an ENMG, besides other complementary laboratory exams were used for screening the above-mentioned patient. Afterwards, current research relating to the topic at hand was made in order to update the data available in the Bireme, Scielo and PubMed Data Banks using the following key words: Fasciculation’s, motor neuron disease, and benign fasciculations in the Portuguese, English as well as Spanish language. Although fasciculation’s are most commonly associated with Motor neuron disease as well as with certain metabolic disorders, they may also be present in individuals with absolutely no underlying pathological disorders. In our case, fasciculation potentials that have been present for six months, with no other signs of a neurogenic disorder as well as absence of laboratory findings, the patient received a diagnosis of Benign Fasciculation Syndrome (BFS.We believe that the use of corticosteroides in high doses with subsequent tapering contributed to the fasciculation’s, especially due to the changes that this causes on the ionic channels. Fasciculation’s are symptoms seen in a large range of conditions, and also being the main symptom of the so-called Benign Fasciculation Syndrome. We have presented an example of this clinical syndrome in a patient whose complaint was fasciculation’s, with complete clinical remission of symptoms following complete tapering off of corticosteroid six months previously.

    Benign thyroid nodules are an extremely common occurrence. Radiofrequency ablation (RFA) is gaining ground as an effective technique for their treatment, in case they become symptomatic. Here we review what are the current indications to RFA, its outcomes in terms of efficacy, tolerability, and cost, and also how it compares to the other conventional and experimental treatment modalities for benign thyroid nodules. Moreover, we will also address the issue of treating with this technique patients with cardiac pacemakers (PM) or implantable cardioverter-defibrillators (ICD), as it is a rather frequent occurrence that has never been addressed in detail in the literature.

    In reproductive women, various physiologic conditions can cause morphologic changes of the ovary, resembling pathologic conditions. Benign ovarian diseases can also simulate malignancies. Magnetic resonance imaging (MRI) can play an important role in establishing accurate diagnosis. Functional cysts should not be confused with cystic neoplasms. Corpus luteum cysts typically have a thick wall and are occasionally hemorrhagic. Multicystic lesions that may mimic cystic neoplasms include hyperreactio luteinalis, ovarian hyperstimulation syndrome, and polycystic ovary syndrome. Recognition of clinical settings can help establish diagnosis. In endometrial cysts, MRI usually provides specific diagnosis; however, decidual change during pregnancy should not be confused with secondary neoplasm. Peritoneal inclusion cysts can be distinguished from cystic neoplasms by recognition of their characteristic configurations. Ovarian torsion and massive ovarian edema may mimic solid malignant tumors. Recognition of normal follicles and anatomic structures is useful in diagnosing these conditions. In pelvic inflammatory diseases, transfascial spread of the lesion should not be confused with invasive malignant tumors. Radiologic identification of abscess formation can be a diagnostic clue. Many benign tumors, including teratoma, Brenner tumor, and sex-cord stromal tumor, frequently show characteristic MRI features. Knowledge of MRI features of these conditions is essential in establishing accurate diagnosis and determining appropriate treatment. (orig.)

    Full Text Available Introduction: Laparoscopic surgery is one of the most common procedures performed for benign ovarian masses. The aim of the study was to analyze all benign ovarian masses treated laparoscopically to assess safety, feasibility and outcome. Methods: A prospective study was carried out at Kathmandu Medical College Teaching Hospital, Sinamangal, Nepal. All the patients undergoing laparoscopic surgery for benign ovarian masses from 1st January 2012 to 31st December 2012 were included in the study. The pre-operative findings, intra-operative findings, operative techniques and post-operative complications were analyzed. Results: Thirty-six patients were taken for the study. Two cases were excluded since intra-operatively they were tubo-ovarian masses. The most common tumor was dermoid cyst (n=13; 38.23% and endometriotic cyst (n=14; 41.17%. Out of 34 cases, five cases of endometriotic cyst (14.70% were converted to laparotomy due to severe adhesions and four cases of endometriotic cyst underwent deroofing surgery. Two cases underwent laparoscopic assisted vaginal hysterectomy with bilateral salphingo-oopherectomy. Successful cystectomies were carried out in 22 cases. None were malignant. Major complications were not noted while minor complications like port-site infection (n=3; 8.82% and subcutaneous emphysema (n=1; 2.9% were present. Conclusions: Laproscopic management of benign ovarian masses is safe and feasible.

    1992-06-01

    Three patients with wasting confined to a single lower limb are reported. The characteristic features were: sporadic occurrence, insidious onset with slow progression and in 2 cases arrested course for at least 4 years, wasting out of proportion with disability, absence of sensory, pyramidal tract or bulbar signs. CK, motor and sensory conductions, and lumbar MRI were normal. Muscle CT showed selective loss of muscle tissue and fat replacement in posterior leg muscles. Quantitative electromyography and histologic findings revealed neurogenic features not only in the affected legs, but also in clinically uninvolved limbs. Monomelic amyotrophy of lower limb is a variant of spinal muscular atrophy with a benign course. However, as in the early stages of the disease there are no distinctive clinical or laboratory findings with other motor neuron diseases, the diagnosis of monomelic amyotrophy may be made only retrospectively after a prolonged observation.

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

    Prostate development follows a common pattern between species and depends on the actions of androgens to induce and support ductal branching morphogenesis of buds emerging from the urogenital sinus. The human prostate has a compact zonal anatomy immediately surrounding the urethra and below the urinary bladder. Rodents have a lobular prostate with lobes radiating away from the urethra. The human prostate is the site of benign hyperplasia, prostate cancer, and prostatitis. The rodent prostate has little naturally occurring disease. Rodents can be used to model aspects of human benign hyperplasia, but care should be taken in data interpretation and extrapolation to the human condition.

    Two cases of benign isolated cutaneous histiocytosis X in newborn infants are reported. Clinically, the lesions mimicked chicken pox, and the histologic findings in skin biopsies were indistinguishable from those described in infantile Letterer-Siwe disease. Electron microscopy showed Langerhans' cells with the classical trilaminar, racket-shaped granules. Our cases a well as 10 of the 21 previously reported cases showed spontaneous resolution of the skin lesions. Since this is a benign spontaneous resolving histiocytosis, we recommend that no therapy be given provided that no other signs of systemic involvement are found.

    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.

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

    To evaluate the usage of duplex power Doppler ultrasound (PDUS) for the differentiation of benign and malignant thyroid nodules. We prospectively examined 77 thyroid nodules in 60 patients undergoing ultrasound-guided fine needle aspiration biopsy (FNAB). Each nodule was described according to size, inner structure, borders, parenchymal echogenicity, peripheral halo formation, and the presence of calcification (Bmode ultrasound findings). Vascularity as determined by PDUS imaging was defined as non-vascular, peripheral, central, or of mixed type. For each nodule, the pulsatility index (PI) and resistive index (RI) values were obtained. Results of FNAB and surgical pathological examination (if available) were used as a proof of final diagnosis to categorize all nodules as benign or malignant. A receiver operating characteristic (ROC) curve analysis was performed to establish cut-off, sensitivity, and specificity values associated with RI-PI values. A significant relationship was observed between malignancy and irregular margins, microcalcifications, and hypoechogenicity on ultrasound examination (p < 0.05). The pattern of vascularity as determined by PDUS analysis was not a statistically significant criterion to suggest benign or malignant disease in this study (p > 0.05). The central, peripheral, and mean RI-PI values were higher in malignant nodules when compared to the other cytologies (p < 0.05). Vascularity is not a useful parameter for distinguishing malignant from benign thyroid nodules. However, RI and PI values are useful in distinguishing malignant from benign thyroid nodules

    2007-01-01

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

    2011-01-15

    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.

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

    Benign paroxysmal positional vertigo (BPPV) is a common disorder that presents to the general practitioner. This condition represents one of the most common causes of peripheral vertigo. The diagnosis is made on clinical grounds. The treatment relies on repositioning maneuvers with relief of symptoms that occur in a few weeks in the majority of the cases. Rarely, patients are incapacitated by persistent or recurrent BPPV despite multiple repositioning maneuvers. In these cases, surgical therapies are available which provide excellent results.

    Full Text Available Pseudoepitheliomatous hyperplasia is an extremely rare condition presenting as a lesion on the glans penis in older men. Physical exam without biopsy cannot differentiate malignant from nonmalignant growth. We report a case of large penile mass in an elderly male with a history of lichen sclerosis, highly suspicious for malignancy. Subsequent surgical removal and biopsy demonstrated pseudoepitheliomatous hyperplasia, an unusual benign histopathologic diagnosis with unclear prognosis. We review the literature and discuss options for treatment and surveillance.

    Purpose The aim of this study was to verify that laparoscopic resection for treating retroperitoneal benign neurilemmoma (NL) is expected to be favorable for complete resection of tumor with technical feasibility and safety. Methods We retrospectively analyzed 47 operations for retroperitoneal neurogenic tumor at Yonsei University College of Medicine, Severance Hospital and Gangnam Severance Hospital between January 2005 and September 2015. After excluding 21 patients, the remaining 26 were divided into 2 groups: those who underwent open surgery (OS) and those who underwent laparoscopic surgery (LS). We compared clinicopathological features between the 2 groups. Results There was no significant difference in operation time, estimated blood loss, transfusion, complication, recurrence, or follow-up period between 2 groups. Postoperative hospital stay was significantly shorter in the LS group versus the OS group (OS vs. LS, 7.00 ± 3.43 days vs. 4.50 ± 2.16 days; P = 0.031). Conclusion We suggest that laparoscopic resection of retroperitoneal benign NL is feasible and safe by obtaining complete resection of the tumor. LS for treating retroperitoneal benign NL could be useful with appropriate laparoscopic technique and proper patient selection.

    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.

    malignant breast diseases with three-dimensional (3D) dynamic enhancement and DWI in high magnetic resonance imaging. Methods Forty-six patients who were suffered breast diseases confirmed by pathology had been scanned with DWI and 3D dynamic enhancement in breast magnetic resonance imaging (MRI), and the ADC pictures respectively were drawn according to different b values of 800 and 1 000 s/mm2. Statistically assess the two kinds of breast diseases′sensitivity, specificity, positive predictive value, and negative predictive value by time-signal intensity curve. Results Among 46 cases, there were 28 patients of malignant breast diseases including 24 cases of infiltrating ductal carcinoma, 3 cases of medullary car-cinoma, and 1 case of lobular carcinoma; 18 cases of benign breast diseases (10 cases of fibroadenoma, 2 cases of atypical hyperplasia, 4 cases of cystic hyperplasia, 2 cases of abscess). When b value was 800 s/mm 2, benign, malig-nant and normal breast tissue′s ADC value were separately (1.54±0.28)×10-3 mm2/s ,(1.01±0.09)×10-3 mm2/s, and (1.49 ±0.06) ×10-3 mm2/s; when it was 1 000 s/mm2, their values were (1.45 ±0.28) ×10-3 mm2/s, (0.90 ±0.08) ×10-3 mm2/s, and(1.49±0.09)×10-3 mm2/s. There was significant statistical difference (P<0.05). The 95%of the reference in-terval in ADC values of malignant and normal breast tissues were(0.97-1.05)×10-3 mm2/s, (0.90-0.97)×10-3 mm2/s. In 28 malignant breast diseases, there were 18 cases of inflow type (64%), 9 cases of platform type(32%), and 1 case of outflow type (3.5%); yet in 18 benign diseases, there were 13 cases of inflow type (72%), 3 cases of platform type (17%), and 1 case of outflow type (6%). The sensitivity, specificity, positive predictive value, and negative predictive value by time-signal intensity curve were 96%(27/28), 83%(15/18) respectively. Conclusion The application of combining 3D dynamic enhancement with DWI sequences could improve distinguish diagnosis of benign and malig-nant breast

    Most men over 50 experience some lower urinary tract symptoms of nocturia, poor stream, urgency and frequency for urination, due to hyperplastic enlargement of the prostate (benign prostate hyperplasia, BPH). BPH is thought to be a disease with multiple aetiologies including hormone signalling, disruption of proliferation and apoptosis dynamics and chronic inflammation with changes in the morphology and phenotype of the prostate stroma. It has been proposed, recently, that stromal stem cells in prostate may be caused by the development of BPH. This review focuses on this putative role of stromal stem or stem-like cells in the development of BPH and assesses the potential of targeting the stem cells for the treatment of BPH.

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

    Female adnexal tumors of probable wolffian origin (FATWOs) are rare. They can closely mimic endometrioid adenocarcinomas with a prominent spindle cell component and Sertoli cell tumors (SCTs). To further define their immunohistochemical profile and origin, we investigated the expression of PAX-8, PAX-2, and GATA binding protein 3 (GATA-3) (wolffian markers) and of steroidogenic factor-1 (SF-1) (sex-cord stromal marker) in FATWOs. We also studied the expression of PAX-8 and PAX-2 in endometrioid adenocarcinomas; of SF-1 in Sertoli-Leydig cell and SCTs; and of PAX-8, PAX-2, GATA-3, and SF-1 in rete ovarii-a proposed site of origin for FATWOs. A database search yielded 8 FATWOs, 18 ovarian/tubal/paraovarian endometrioid adenocarcinomas, and 8 ovarian Sertoli-Leydig cell and SCTs. Eleven cases with rete ovarii sections were included. Of the FATWOs studied, all were negative for PAX-8, PAX-2, GATA-3, and SF-1. Of the endometrioid adenocarcinomas studied, PAX-8 was positive in all and PAX-2 was positive in 57%. Of the Sertoli-Leydig cell and SCTs, all were positive for SF-1 except one. The rete ovarii were positive for PAX-8, weakly positive for SF-1, and negative for PAX-2 and GATA-3. Our study suggests that PAX-8 and SF-1 can be helpful in the distinction between FATWOs and endometrioid adenocarcinomas and SCTs, respectively. Our results do not support a Mullerian or sex-cord stromal or rete ovarii origin for FATWOs. It is curious, however, that FATWOs do not express wolffian markers-it is possibly related to their origin from a distinctive portion of the wolffian duct.

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

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

    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.)

    Full Text Available Purpose: Family history is associated with gliomas, but this association has not ben established for benign brain tumors. Using information from newly diagnosed primary brain tumor patients, we describe patterns of family cancer histories in patients with benign brain tumors and compare those to patients with gliomas. Methods: Newly diagnosed primary brain tumor patients were identified as part of the Ohio Brain Tumor Study (OBTS. Each patient was asked to participate in a telephone interview about personal medical history, family history of cancer, and other exposures. Information was available from 33 acoustic neuroma (65%, 78 meningioma (65%, 49 pituitary adenoma (73.1% and 152 glioma patients (58.2%. The association between family history of cancer and each subtype was compared with gliomas using unconditional logistic regression models generating odds ratios (ORs and 95% confidence intervals (95% CI. Results: There was no significant difference in family history of cancer between patients with glioma and benign subtypes. Conclusions: The results suggest that benign brain tumor may have an association with family history of cancer. More studies are warranted to disentangle the potential genetic and/or environmental causes for these diseases.

    The prostate is an androgen-sensitive organ that needs proper androgen/androgen receptor (AR) signals for normal development. The progression of prostate diseases, including benign prostate hyperplasia (BPH) and prostate cancer (PCa), also needs proper androgen/AR signals. Tissue recombination studies report that stromal, but not epithelial, AR plays more critical roles via the mesenchymal-epithelial interactions to influence the early process of prostate development. However, in BPH and PCa,...

    Цель. Операции при доброкачественных заболеваниях и повреждениях пищевода производятся преимущественно из традиционных хирургических доступов (торако- и лапаротомии) и характеризуются высокой травматичностью. С учетом малой травматичности видеоэндохирургических вмешательств, более ранней реабилитации и улучшения качества жизни оперированных больных необходимость разработки и анализа полученных результатов после этих операций является актуальной. Материал и методы. С использованием видеоэндохирургических технологий нами оперированы 159 пациентов с доброкачественными заболеваниями и перфорацией пищевода. С ахалазией кардии было 72 (45,3%) больных, послеожоговым рубцовым стенозом пищевода — 56 (35,2%), перфорацией пищевода — 14 (8,8%), лейомиомой пищевода — 13 (8,2%), дивертикулом грудного отдела пищевода — 4 (2,5%) больных. Результаты и обсуждение. В отдаленные сроки после видеолапароскопической эзофагокардиомиотомии по Геллеру с гемиэзофагофундопликацией по Дору по поводу ахалазии кардии обследованы 56 пациентов, у всех наблюдали хороший результат. После видеоторакоскопической экстирпации пищевода с эзофагопластикой из лапаротомного доступа на этапе освоения метода в раннем послеоперационном периоде умерли 3 больных. В группе больных, перенесших видеоторакоскопическую экстирпацию пищевода с одномоментной лапароскопической гастропластикой, летальных исходов не было. После видеоторакоскопической экстирпации пищевода с одномоментной видеолапароскопической эзофагогастропластикой целым желудком длительность послеоперационного периода была достоверно меньше, чем после эзофагогастропластики и эзофагоколопластики из лапаротомного доступа. В отдаленном послеоперационном периоде у 17 человек возникли различные осложнения. После видеолапаротрансхиатального дренирования заднего средостения по поводу перфорации пищевода умерли 2 больных, у остальных произошло рубцевание дефекта стенки пищевода. Несостоятельность шва после удаления лейомиомы пищевода отмечена у 2 больных, что потребовало видеолапаротрансхиатального дренирования заднего средостения и видеоассистированной еюностомии по Майдлю, после чего наступило выздоровление.

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

  1. Palladium-Catalyzed Environmentally Benign Acylation.

    Suchand, Basuli; Satyanarayana, Gedu

    2016-08-05

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

  2. The debate over robotics in benign gynecology.

    Rardin, Charles R

    2014-05-01

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

    2012-01-01

    Full Text Available Polycythaemia has been reported rarely as a familial condition. There is evidence to suggest transmission as a Mendelian dominant trait, but recessive inheritance has also been described. We present here a case of benign familial polycythaemia in a 25-year-old male with similar presentation in his family members. Our patient presented with reddish discolouration of eyes, early satiety , weight loss and itching at intervals for four years. An additional examination revealed red beefy tongue and Grade III clubbing. The importance of presenting this case lies in the fact that the prognosis appears to be good in these patients, but regular observation is necessary as Kiladjian and colleagues have mentioned that there is a risk of leukaemia, thrombosis and myelofibrosis in these patients later on, as the idiopathic erythrocytosis group contains a certain number of polycythaemia patients.

    2016-01-01

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

    2015-01-01

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

    Full Text Available Geriatric population in India is rapidly increasing. According to one estimate the number of persons above the age of 60 years is 76.6 million in India. India as the second most populous country in the world, with elderly people constituting 7.7% of total population. The morbidity in this age group is often due to increased incidence of falls. It is often preceded with spells of dizziness and often associated with vestibular disorders. Peripheral vestibular disorders often difficult to evaluate at the time of fall and only realized after the fall. Peripheral vestibular disorders like Benign Paroxysmal Positional Vertigo (BPPV, Vestibulopathy, Vestibular Neuritis are some of the disorders that affect geriatric population that affect the functional ability in ‘activities of daily living (ADL. BPPV has been frequently found to be more common with advancing age. One simple test to assess ADL (Activities of Daily Living is TUG test (Timed Up and Go. A score of 11.1 seconds or more on TUG test was correlated with 80% chance of a fall in the elderly. Hence a study is undertaken to evaluate peripheral vestibular disorders in elderly with special reference to BPPV along with their performance on TUG (Timed Up and Go test. Benign Paroxysmal Positional Vertigo (BPPV has been found to be most common vestibular disorder in the elderly . One out of four elderly with Peripheral vestibular disorder has a risk of ‘fall’. BPPV is the most common peripheral vestibular disorder leading to ‘risk of fall’ three times more among the elderly after 75years .

    Full Text Available BACKGROUND Despite the fact that in majority of cases the initial symptom of benign breast disease is a lump, which can be easily detected by the patient herself by self-examination they generally present at a very late stage and this poses a great difficulty in their management. Early and appropriate diagnosis of breast disease is of utmost importance. AIM The aim of the study was to find out the relative frequency and commonest site of occurrence of benign breast disorder and their relationship with age, parity, menstrual cycle, and socio-economic status and also to find out the accuracy of investigative procedures in their diagnosis. DESIGN This is a cross sectional, interventional. Hospital based study. MATERIALS AND METHOD This study was done in 58 female patients in the age group 10 yrs. to 55 yrs. presenting with clinically benign breast lumps randomly chosen from outpatient department and indoor wards of The Calcutta Medical Research Institute, Kolkata. After taking an accurate history and proper clinical examination these patients were sequentially studied by radiological methods (Ultrasonography and mammography, fine needle aspiration cytology (FNAC and histopathology of removed specimen. Patients were enquired about their age, chief complaints, menstrual history, and use of oral pill, marital status, parity, lactation and socioeconomic status. RESULTS 79% of the benign breast lumps were found to be between 10–35 years, Fibro adenoma being the commonest one (41.38% and fibrocystic disease the second most common (29.31%. Breast lump were more common among unmarried and nulliparous females (48.27%, commonest site being upper and outer quadrant (38.8%. 69% patients were associated with an abnormal menstrual status. 76% of the cases were accurately diagnosed by clinical examination, 70% by mammography, 88% by FNAC and 84% by ultrasonography. CONCLUSION This clinicopathological study of benign breast lump is a small endeavour on our part

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

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

    Full Text Available Abstract Background Caveolin-1 is thought to have an important impact on both signal transduction and mediation of intracellular processes. Furthermore, it has been suggested that Caveolin-1 may contribute to certain steps of carcinogenesis in various types of cancer. We examined the potential clinical relevance of Caveolin-1 in normal, benign and malignant breast tissue specimens. Methods Using tissue microarray (TMA technology cases of invasive breast cancer, DCIS, benign breast disease (i.e. fibroadenoma, sclerosing adenosis, ductal hyperplasia and radial scar and normal breast tissue were evaluated for Caveolin-1 expression. Immunohistochemical staining with an anti-Caveolin-1-antibody was performed. Staining intensity was quantified semiquantitatively. In invasive lesions staining results were correlated with clinical and pathological data. Results No Caveolin-1 expression was observed in epithelial cells of normal breast tissue (n = 5, benign breast disease (n = 295 and DCIS (n = 108. However, Caveolin-1 expression was found in 32 of 109 cases of invasive breast carcinomas (29.4%. Caveolin-1 expression in invasive breast cancer could neither be correlated with survival parameters such as overall or disease-free survival nor with established clinical and pathological markers. Conclusion In this study we demonstrated expression of Caveolin-1 in one third of invasive breast cancers. A significant increase in Caveolin-1 expression was observed comparing invasive breast cancer to both benign breast tissue and non-invasive breast cancer. Since inhibitors of Caveolin-1 signalling are available, targeting Caveolin-1 in breast cancer may represent a potential option for future breast cancer treatment.

    Introduction: Different imaging modalities are used to evaluate salivary gland diseases, including tumors. Ultrasonography (US) is the preferred method on account of its ease of use, affordability, safety profile, and good tolerance among patients. The aim of this study was to evaluate the role of US in differentiating malignant from benign parotid tumors, in the context of previous controversy in the literature on this subject. Materials and Methods: A cross-sectional study was performed in patients who presented to Qaem Medical Center with parotid masses and who were candidates for parotidectomy between June 2013 and January 2015. Patients were initially referred for a diagnostic US of the parotid. US examinations were performed and sonographic features were reported. The tumors were then classified as benign or malignanton the basis of literature descriptions of the US features of parotid tumors, and were next diagnosed pathologically. The sensitivity, specificity, positive predictive value, and negative predictive value of US for the purpose of differentiating malignant from benign tumors were then calculated. Results: Twenty-eight patients (aged 18–92 years) underwent US of parotid masses. Twenty-three tumors were diagnosed as benign and five were diagnosed as malignant. The final histopathologic examination showed 21 benign and seven malignant tumors. The sensitivity, specificity, positive predictive value, and negative predictive value of US for differentiating malignant from benign tumors were calculated as 57%, 95%, 80%, and 87%, respectively. Conclusion: US has a high specificity in differentiating between malignant and benign tumors. However, fine needle aspiration or core needle biopsy is advocated for an exact diagnosis. PMID:27738606

Benign prostatic hyperplasia is a benign enlargement of the prostate gland. Clinical features of this disease are one of the most common problems encountered by elderly males. The aim of this study was to assess the appropriateness of benign prostatic hyperplasia surgery. Materials & Methods: In this qualitative study which was conducted in 2008-9, in Tehran University of Medical Sciences, the RAN/UCLA method was used, which was designed in 1980 by the RAND institute and the University of California in Los Angeles. Regarding the stages of our method, scenarios and indications for benign prostatic hyperplasia surgery were chosen from the latest approved scientific resources and subsequently sent to urology specialists, who were chosen as members of the specialized panel. Panel members gave scores ranging from 1 to 9 to each indication and scenario based on scientific resources, clinical experiences and patient’s condition in two separate panel sessions. After compilation, the indications were finally grouped as appropriate, equivocal, and inappropriate so that they could be used to determine appropriateness of benign prostatic hyperplasia surgery in hospitals. In this study, the most suitable and most approved clinical guidelines related to benign prostatic hyperplasia, the Guidelines Evaluation and Research Appraisal (AGREE were used.The selected guidelines were used as scientific resources for choosing the indications of benign prostatic hyperplasia surgery. SPSS version 16 and kappa weighted value were used in analysis process of the study. Results: Out of 282 scenarios grouped as 9 conditions related to benign prostatic hyperplasia surgery, which were extracted from scientific sources, 73 cases (25.9% were considered as appropriate, 14 cases (5% as equivocal and 7 cases (2

    Full Text Available Abstract Background Chyluria is a medical condition with presence of chyle in the urine. The disease is most prevalent in endemic regions of Africa and the Indian subcontinent where it is mostly caused by parasitic infections, particularly lymphatic filariasis due to wucheria bancrofti. Non-parasitic chyluria, however, is a very rare finding. Case Presentation We report the case of a 48 year old woman who developed a lymphorenal fistula with chyluria following ureterrenoscopy with biopsies taken for urological work-up of persistent macrohematuria. Renal biopsy confirmed the diagnosis of benign familial hematuria due to thin basement nephropathy, a condition frequently associated with episodes of macrohematuria. Conclusions This case highlights a rare case of non-parasitic chyluria as a complication of urological work-up for macrohematuria of benign nature.

    Diagnostic problems attending intraosseous and parosteal pseudoneoplastic lesions can be radiographic, or histological, or both. Proliferations in this category may contain cellular fibro-osseous or chondro-osseous tissues that are difficult to separate microscopically from those seen in various true neoplasms of the bones. This review considers the clinicopathologic features of fibrous dysplasia, benign fibro-osseous lesions of the jawbones, osteofibrous dysplasia, metaphyseal fibrous defect, giant-cell reparative granuloma, "brown tumor" of hyperparathyroidism, synovial chondrometaplasia, aneurysmal bone cyst, tumefactive chronic osteomyelitis, proliferative Paget disease, and polyvinylpyrrolidone storage disease of bone.

    Spontaneous subperiosteal hemorrhage is a rare complication of von Recklinghausen's disease. There are few reports describing the MR imaging characteristics of this entity. Our case is unique among these as an underlying plexiform neurofibroma was visualized by MR imaging. We present a 12-year-old child with neurofibromatosis 1 who presented with a rapidly enlarging mass of the fibula. Surgery and pathology revealed subperiosteal hemorrhage into a benign, plexiform neurofibroma. The MR imaging features, pathogenesis and clinical implications of this entity are discussed. Recognition of this disease process and differentiating it from malignant transformation can prevent unnecessary surgery. (orig.)

    As the result of the ecological impacts from the use of tributyltins (TBT) in shipping, environmental legislation for the registration of chemicals for use in the environment has grown to a monumental challenge requiring product dossiers to include information on the environmental fate and behavior of any chemicals. Specifically, persistence, bioaccumulation and toxicity, collectively known as PBT, are properties of concern in the assessment of chemicals. However, existing measurements of PBT properties are a cumbersome and expensive process, and thus not applied in the early stages of the product discovery and development. Inexpensive methods for preliminary PBT screening would minimize risks arising with the subsequent registration of products. In this article, we evaluated the PBT properties of compounds reported to possess anti-fouling properties using QSAR (quantitative structure-activity relationship) prediction programs such as BIOWIN™ (a biodegradation probability program), KOWWIN™ (log octanol-water partition coefficient calculation program) and ECOSAR™ (Ecological Structure Activity Relationship Programme). The analyses identified some small (Mr < 400) synthetic and natural products as potential candidates for environmentally benign biocides. We aim to demonstrate that while these methods of estimation have limitations, when applied with discretion, they are powerful tools useful in the early stages of research for compound selection for further development as anti-foulants.

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

    The Authors present the first case described among us of benign pleural effusion of an asbestotic origin. They stress the importance of thoracoscopy (pleuroscopy) in the diagnosis of this situation. Attention is drawn to the fact that asbestotic lesions and asbestotic bodies have been found in the lung and, in particular, in the parietal pleura as well. They emphasize the fact that exposure to asbestos was not realized by the patient, which made the clarification of the situation more difficult. It was a CT scan that showed the signs suggestive of exposure to asbestos which raised the diagnostic suspicion. They conclude that every patient with a pleural effusion must be thoroughly questioned about exposure to asbestos. Even if the exposure is accepted, they consider that one should proceed to a pleuro-pulmonar biopsy by thoracoscopy. This biopsy allows demonstration of the characteristic histopathological lesions and rule out other etiologies, namely malignancy and tuberculosis. They suggest that these patients must be highly motivated to stop any smoking and kept under periodic surveillance.

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

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

    Full Text Available Fibronectin (FN is a multifunctional glycoprotein involved in cell-matrix interactions. It exhibits a complex pattern of forms differing in respect to aminoacid and oligosaccharide composition. In this study we examined glycobiochemical and functional properties of the FN in benign prostatic hyperplasia (BPH and prostatic cancer (PCa, attempting to resolve disease-related differences. Two BPH sera pools and three PCa sera pools were used as the FN source. The affinity-purified molecule was characterized by SDS-PAGE, immuno- and lectin blot, lectin-affinity chromatography and adhesion assay. BPH FN existed as intact molecule, giving the main immunoreactive band at 220 kDa. In contrast, PCa FN comprised three main immunoreactive fragments of 140, 110 and 90 kDa. As for glycosylation the ratio of altogether lectin-reactive PCa FN was different from that of BPH FN manifested as a decrease of Con A- and an increase of LCA-reactive moieties. Fibroblasts adhered to both FN preparations in a concentration dependent manner, but with a significantly lower efficiency to PCa FN. The results obtained showing distinct structural characteristics of PCa FN compared to BPH FN could be important for modulation of its ligand and recognition properties expressed as gain or loss of functions or as specific markers of its origin.

    Benign prostatic hyperplasia (BPH) is an age-related disease of unknown etiology characterized by prostatic enlargement and coinciding with distinctive alterations in tissue histomorphology. To identify the molecular mechanisms underlying the development of BPH, we conducted a DNA microarray study using a previously described animal model in which chronic alpha(1)-adrenergic stimulation by repeated administration of phenylephrine evokes histomorphological changes in the rat prostate that resemble human BPH. Bioinformatic tools were applied to microarray data obtained from prostate tissue to construct a network model of potentially relevant signal transduction pathways. Significant involvement of inflammatory pathways was demonstrable, including evidence for activation of a TGF-beta signaling cascade. The heterodimeric protein clusterin (apolipoprotein J) was also identified as a prominent node in the network. Responsiveness of TGF-beta signaling and clusterin gene and protein expression were confirmed independently of the microarray data, verifying some components of the model. This is the first attempt to develop a comprehensive molecular network for histological BPH induced by adrenergic activation. The study also implicated clusterin as a novel biochemical target for therapy.

    We report here magnetic resonance imaging (MRI) findings of two patients with benign monomelic amyotrophy of lower limb. Both subjects showed unilateral amyotrophy of the lower limb with a benign clinical course, and the affected muscles demonstrated neurogenic changes. On T1- and T2-weighted MRI, marked atrophy and increased signal intensity were found mainly in gastrocnemius and soleus muscles. Moreover, MRI examination also revealed that thigh muscles including semitendinosus, semimembranosus, and vastus intermedius and lateralis muscles were involved in one of the patients. We concluded that muscle MRI is very useful for detecting affected muscles, especially deep skeletal muscles in patients with benign monomelic amyotrophy of lower limb.

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

    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.

    Full Text Available Dizziness is one of the common reasons for visits to physicians of various specialties; the data of foreign investigations show that benign paroxysmal positional vertigo (BPPV is most frequently encountered.Objective: to study the causes of dizziness, to analyze the frequency of BPPV and the efficiency of its treatment in outpatient practice.Patients and methods. The investigation enrolled 80 patients, including 55 (68.7% women and 25 (31.3% men, aged 18 to 75 years (mean age 53.8±12.8 years, who complained of dizziness and sought for medical advice in the Therapeutic-and-Diagnostic Unit, A.Ya. Kozhevnikov Clinic of Nervous System Diseases, I.M. Sechenov First Moscow State Medical University.Results. The most common causes of dizziness in outpatient practice were BPPV (46.2% and postural phobic vertigo (35%. The diagnosis of VPPV, if special positional testing (Dix-Hallpike and McClure-Pagnini tests was carried out, was shown to create no significant difficulties. The diagnosis was not established in the majority (97.5% of the patients; effective treatment was performed in one of the patients. Combined treatment, by performing the positional tests and using betaserc for 2 months, led to complete resolution of positional vertigo in most (97.3% patients.Discussion. The findings indicate the efficiency of examining patients with complaints of dizziness, by using the special otoneurological tests to detect BPPV. The purposeful questioning of patients with BPPV can suspect this disease in the majority of cases. Our investigation shows the high efficiency of rehabilitation maneuvers for BPPV, which agrees well with the data of other authors. Physicians’ poor awareness of BPPV among physicians and the high efficiency of its treatment in outpatient practice are noted.

Paired CSF/serum samples of 406 patients with neurological disorders were submitted to isoelectric focusing with immunodetection of IgG. Ninety-two patients had definite MS; non-MS cases were assembled in groups inflammatory/infectious diseases (ID, n=141 and other/controls (OD, n=173. We found in the MS group: mean duration, 38.9 months; clinically isolated syndromes, 24%; relapsing/remitting course (RR, 65%; in RR patients the mean EDSS was 2.1 and the mean index of progression was 0.31. Positive patterns significantly predominated in MS (82.6%; ID, 40.4%; OD, 3.5%. The sensitivity and the specificity of positive IgG-OCB for MS diagnosis was 82.6% and 79.9%, respectively. The sole statistically significant difference in the MS group was the lower progression index observed in negative cases. We conclude that the frequency of positive IgG-OCB patterns in our MS patients fits most values reported in the literature, and that negative results indicate benign disease.Analisamos a frequência de bandas oligoclonais (BOC restritas ao líquido céfalo-raquidiano (LCR em doentes portugueses com esclerose múltipla (EM e sua relação com a clínica.

    Objective To observe the influence of reperfusion after adnexal torsion (AT) on malondialdehyde (MDA), glutathione peroxidase catalase (GSH-Px) and catalase (CAT) contents of ovarian tissue in rabbits. Methods Forty female Japanese long-eared white rabbits were randomly divided into study group (n=32) and control group (n=8). The left adnexa of rabbits in the study group was clockwise twisted three laps, and then fixed on the left abdominal walls. Adnexal detorsion was then done 24 hours after adnexal torsion in the study group, and then the rabbits were divided into 4 groups (8 each). Both ovaries of each group were removed 24h, 48h, 72h and 96h, respectively, after reperfusion. The rabbits in the control group received sham-operation and both ovaries were removed 96h later. The removed left ovaries were used for biochemical detection of GSH-Px, CAT and MDA. All the right ovaries were used as experimental internal-control. Results The activity of GSH-Px declined significantly 24h to 72h after adnexal detorsion (P0.05). The activity of CAT declined significantly 24h and 48h after adnexal detorsion (P0.05).

    Full Text Available Early detection of breast cancer by means of thermal imaging has a long and extremely controversial history. Recently, the availability of highly sensitive infrared (IR cameras which can produce high-resolution diagnostic images of the temperature and vascular changes of breasts, as well as a better knowledge of advanced image processing techniques, has generated a renewed interest. The objective of this study is to investigate fractal analysis of breast thermal images and to develop an algorithm for detecting benignity and malignancy of breast diseases. The study is based on IR images captured by thermal camera, in which the resolution of the results is within the state of the art of IR camera. A total of 7 malignant cases and 8 benign cases have been considered. The breast images were first segmented by fuzzy c-means clustering. Then the first hottest regions for each image were identified and the fractal dimension of those regions was computed. It is shown that the fractal dimension results significantly differ between malignant and benign patterns, suggesting that fractal analysis may potentially improve the reliability of thermography in breast tumor detection.

    Full Text Available Panayiotopoulos syndrome (PS is a relatively frequent and benign epileptic syndrome seen in children in the age group of 3-6 years and is characterised by predominantly autonomic symptoms and/or simple motor focal seizures followed or not by impairment of consciousness. Although multifocal spikes with high amplitude sharp-slow wave complexes at various locations can be present in the EEG, interictal electroencephalogram (EEG in children with this particular type of epilepsy characteristically shows occipital spikes. This syndrome has known to be a masquerader and can imitate gastroenteritis, encephalitis, syncope, migraine, sleep disorders or metabolic diseases. In the absence of thorough knowledge of types of benign epilepsy syndromes and their various clinical presentations, epilepsy such as PS can be easily missed. The peculiar aspects of this type of epilepsy in children should be known not only by paediatricians but also by general doctors because a correct diagnosis would avoid aggressive interventions and concerns on account of its benign outcome. In this case study, we report a case of PS in a 3 year old child.

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

    Ossifying fibroma (OF) and fibrous dysplasia (FD) are benign, intraosseous, proliferative fibro-osseous lesions (PFOLs) characterized by replacement of normal bone by a fibrous matrix with various degrees of mineralization and ossification. Osteomas are benign tumors composed of mature, well-differentiated bone. Clinical, imaging, and histologic features of 15 initially diagnosed benign PFOLs and osteomas of the canine oral cavity were evaluated. Final diagnoses after reevaluation were as follows: OF (3 cases), FD (4 cases), low-grade osteosarcoma (LG-OSA) (3 cases), and osteoma (5 cases). Histology alone often did not result in a definitive diagnosis for PFOL. OF appeared as a well-circumscribed, radiopaque mass with some degree of bone lysis on imaging. Most lesions of FD showed soft tissue opacity with bone lysis and ill-defined margins. Low-grade OSA appeared as a lytic lesion with a mixed opacity and ill-defined margins. Osteomas were characterized by a mineralized, expansile, well-circumscribed lesion. Although histologic features of PFOLs were typically bland, the lesions diagnosed as LG-OSA had some features of malignancy (eg, bone invasion or a higher mitotic index). Treatment varied widely. Of the 10 dogs with benign PFOL or osteoma with known outcome (10/12), 9 showed either complete response (6/10) or stable disease (3/10) after treatment. Of the 2 dogs with LG-OSA with known outcome, 1 showed complete response after curative intent surgery, but 1 patient had recurrence after partial maxillectomy. Definitive diagnosis of mandibular/maxillary PFOL is challenging via histopathologic examination alone, and accurate diagnosis is best achieved through assimilation of clinical, imaging, and histopathologic features.

    Background: Colorectal cancer will present itself as a bowel obstruction in 16-23% of all cases. However, not all obstructing tumors are malignant and the differentiation between a benign and a malignant tumor can be difficult. The purpose of our study was to determine whether fast dynamic gadolinium-enhanced MR imaging combined with MR colonography could be used to differentiate a benign from a malignant obstructing colon tumor. Methods: Patients with benign colon tumor stenosis, based on diverticulitis, were asked to participate in the study. The same number of patients with verified colorectal cancer was included. Both groups had to be scheduled for surgery to be included. Two blinded observers analyzed the tumors on MR by placing a region of interest in the tumor and a series of parameters were evaluated, e.g. wash-in, wash-out and time-to-peak. Results: 14 patients were included. The wash-in and wash-out rates were significantly different between the benign and malignant tumors, and a clear distinction between benign and malignant disease was therefore possible by looking only at the MR data. Furthermore, MR colography evaluating the rest of the colon past the stenosis was possible with all patients. Conclusion: The results showed the feasibility of using fast dynamic gadolinium-enhanced MR imaging to differentiate between benign and malignant colonic tumors. With a high intra-class correlation and significant differences found on independent segments of the tumor, the method appears to be reproducible. Furthermore, the potential is big in performing a full preoperative colon evaluation even in patients with obstructing cancer. Trial number: (NCT00114829).

    Genetic diseases that do not primarily affect the genitourinary tract may have urologic manifestations. These urologic manifestations range from benign and malignant renal disease to infertility. Thus, the practicing urologist may be involved in the care of these patients and should have knowledge of these diseases. Continued improvements in the diagnosis and treatment of these genetic diseases will likely result in improved survival and will increase the number of patients who may develop urologic manifestations of these diseases.

    Background:Meig’s syndrome is a rare syndrome characterized by a triad of recurrent pleural effusions, ascites, and the finding of a benign ovarian fibroma on diagnostic imaging and histopathological evaluation. Patients can present with any of the constellation of symptoms attributing to the disease state. With pleural effusions they can present with shortness of breath, chest pressure, dyspnea on exertion; symptoms that can be confused with the exacerbation of congestive heart failure. Ascites can present with abdominal tenseness, pain, bloating, cramping, constipation, and elevated liver enzymes. The ifnding of a benign ovarian ifbroma is found only during diagnostic imaging and histopathological evaluation. Case report:The patients was an 85-year-old female with a recent history of coronary artery bypass graft surgery for her severe coronary artery disease presented with the chief complaint of generalized malaise, abdominal pain, constipation of few days. She was initially scheduled to have her second therapeutic thoracentesis for her recurrent pleural effusion as an outpatient procedure but complained of the former symptoms and was admitted for observation and treatment of her abdominal symptoms. Her recurrent pleural effusions were initially attributed to the complications of her coronary artery bypass graft surgery for her severe coronary artery disease. During the admission and evaluation she was diagnosed with Meig’s syndrome. She underwent a left oophorectomy with total abdominal hysterectomy that led to the resolution of all her symptoms. Conclusion:Meig’s syndrome is a rare syndrome characterized by the triad of recurrent pleural effusions, ascites, and the ifnding of a benign ovarian ifbroma. The diagnosis and knowledge of this syndrome holds the key to its treatment. The treatment generally involves the resection of the ovarian ifbroma. After the resection of the ovarian ifbroma patients recover from the inconvenient pleural effusions and

    Previous occupational asbestos exposure (more rarely environmental or domestic exposure) may induce various pleural and/or pulmonary, benign or malignant diseases, sometimes with a very long latency for malignant mesothelioma (MM). Asbestos has been widely extracted and used in Western countries and in emerging or developing countries, resulting in a peak of MM incidence in France around 2020 and likely in a world pandemic of asbestos-induced diseases. These patients have mostly benign respiratory diseases (pleural plugs) but may also be diagnosed with lung cancer or malignant pleural mesothelioma, and have a global poor outcome. New therapeutic tools (targeted therapies, immunotherapy…) with first promising results are developed. However, it is crucial to obtain a full ban of asbestos use worldwide, and to do a regular follow-up of asbestos-exposed subjects, mostly if they are already diagnosed with benign respiratory diseases. Finally, new cancers (larynx and ovary) were recently added to the list of asbestos-induced tumors.

    Full Text Available Abstract Introduction Benign paroxysmal positional vertigo (BPPV is the most common type of vertigo. It is frequently seen in elderly patients, and the course of the attack may easily mimic cerebrovascular disease. A BPPV attack after a radiologic examination has not been reported previously. We report the cases of two patients who had BPPV attacks after radiologic imaging. Case presentation The first patient with headache and tremor was admitted to the radiology department for cranial computed tomography (CT imaging. During scanning, she was asked to lie in the supine position with no other head movements for approximately 10 minutes. After the cranial CT imaging, she stood up rapidly, and suddenly experienced a vertigo attack and nausea. The second patient was admitted to the radiology department for evaluation of his renal arteries. During the renal magnetic resonance angiography, he was in the supine position for 20 minutes and asked not to move. After the examination, he stood up rapidly with the help of the technician and suddenly experienced a vertigo attack with nausea and vomiting. The results of standard laboratory analyses and their neurologic examinations were within normal limits and Dix-Hallpike tests showed rotatory nystagmus in both cases. An Epley maneuver was performed to the patients. The results of a control Dix-Hallpike tests after 1 Epley maneuver were negative in both patients. Conclusion Radiologists and clinicians must keep in mind that after radiologic imaging in which the patient is still for some time in the supine position and then helped to stand up rapidly, a BPPV attack may occur.

    Full Text Available Abstract Background Despite its frequent occurrence and effective treatment options, benign paroxysmal positional vertigo (BPPV still remains under-estimated in the community. Methods We reviewed referral letters and medical records of 120 patients who were treated for BPPV at our Dizziness Clinic during the years 2006–2008 and searched for factors that possibly contribute to missing this entity. Results The referral diagnosis could be clustered into four groups: BPPV (25.6%, further unspecified vertigo (36.6%, dizziness (27.5% and other (10%. BPPV was recognized more frequently by ENT doctors than by other specialists. Patients referred with the correct diagnosis of BPPV were significantly younger and the duration of their symptoms shorter than in other referral groups. Patients in the distinct referral groups did not differ in the presence of autonomic symptoms or a history of another serious disease. A history typical of BPPV could be obtained in all but 11 patients, but position dependence was noted by the referring physician only in 55 patients, 31 of them correctly assigned as possible BPPV. Only in two patients was the Dix-Hallpike test performed. Thirty two patients were diagnosed with BPPV in the past, but this did not influence the recognition of the recurrence of this clinical entity. About 40% of patients had an audiogram and/or brainstem auditory evoked potentials. Electronystagmography was performed in 7.5% and brain imaging in 14% of patients before referral. Conclusion Our results show that BPPV is still an under-recognized entity. Education and the demand on specialists to learn how to treat BPPV, could improve the situation.

    Full Text Available Objective To explore the clinical features of benign paroxysmal positional vertigo (BPPV in patients of 40 years old or younger. Methods The clinical features of 40 patients (age ≤40 years with BPPV admitted from August 2009 to July 2011 were retrospectively analyzed, and compared with that of 286 middle and old-aged patients (age >40 years with BPPV admitted in the same period. Results The incidence of BPPV in young patients showed a relatively higher incidence (12.3%, with the sex ratio of male to female 1:3 and a mean age of 32.1±6.2 years. The mean latent period of vertigo attack was 1.2±1.3 seconds, and 10 patients (25% showed no obvious latent period. The median duration of vertigo was 10s. The posterior semicircular canal was involved in 27 patients (67.5%. Cupulolithiasis was found in 6 patients, and all the otolithiasis was found to involve the posterior semicircular canal. The proportion of BPPV with no obvious latency was higher in the young patients than in the middle and old-aged patients (25.0% vs 11.5%, χ2=5.554, P=0.018, but no significant difference in sex ratio, the course of disease, the ratio of involved semicircular canal, the latency and the duration of vertigo attack was found between two groups (P>0.05. Conclusions The incidence of BPPV is relatively higher in youth, more common in females, and the posterior semicircular canal is commonly involved. Compared with the middle and old-aged patients with BPPV, the proportion patients with no obvious latency of vertigo attack in young patients is higher, and the incidence of cupulolithiasis involving posterior semicircular canal is higher in the youth.

    Health-related quality of life (HRQoL) assessments are increasingly used to evaluate treatment effects and to shape the delivery of value based care. Valid generic and disease specific tools are available for quantifying HRQoL in patients with non-toxic goitre. However, few studies have applied...... these validated instruments to assess HRQoL in patients with benign non-toxic goitre. Limited evidence suggests that patients with non-toxic goitre have HRQoL impairments in multiple HRQoL domains. While the HRQoL-impact of non-toxic goitre may be small relative to other severely disabling medical conditions...

    INTRODUCTION: The gastrointestinal manifestations of Henoch-Schonlein purpura (HSP) are well characterised, but their recognition can be difficult when they occur in isolation. Furthermore, HSP can run a more serious course in adults, compared to children, in whom the disease usually occurs. MATERIALS AND METHODS: We describe two cases that illustrate the challenges of HSP with mesenteric vasculitis and the outcome in adults. CONCLUSION: Although self-limiting in most patients, the outcome of HSP in adults can be far from benign and even fatal.

  14. Lack of a Benign Interpretation Bias in Social Anxiety Disorder

    Science.gov (United States)

    Amir, Nader; Prouvost, Caroline; Kuckertz, Jennie M.

    2013-01-01

    Cognitive models of social anxiety posit that recurrent interpretation of ambiguous information as threatening maintains symptoms (e.g. Clark & Wells, 1995, pp. 69–93, Social phobia: Diagnosis, assessment, and treatment. New York: Guilford Press; Rapee & Heimberg, 1997, pp. 741–756, Behavior Research and Therapy, 35). However, biased interpretation may also be represented as a failure to make a benign interpretation of the ambiguous event. Furthermore, interpretation bias can be characterized by both an online (automatic) component and an offline (effortful) component (Hirsch & Clark, 2004, pp. 799–825, Clinical Psychology Review, 24). To measure both benign and threat biases, as well as examine the effect of social anxiety on offline versus online interpretations, Beard and Amir (2009, pp. 1135–1141, Behaviour Research and Therapy, 46) developed the Word Sentence Association Paradigm (WSAP). In the current study, we administered the WSAP to a group of participants diagnosed with social anxiety disorder (SAD) as well as to a group of non-anxious control (NAC) participants. We found that participants with SAD demonstrated a lack of benign online bias, but not an online threat bias when compared to NACs. However, when examining offline biases, SAD patients endorsed social threat interpretations and rejected benign social interpretations to a greater degree than non-anxious individuals. Our results, when taken together, clearly implicate the role of reduced bias toward benign information in SAD. PMID:22545788

    Assessment tools and body-composition measurements are useful in diagnosing malnutrition. Which one is better for lung disease patients is unclear. The objectives of the present study are: to assess relationships between different methods of nutritional measurements in lung diseases patients; to determine which one is better in diagnosing malnutrition for lung disease patients; and to determine whether lung cancer patients can be differentiated from benign lung disease patients using different measurements. A total of 96 newly diagnosed primary lung cancer patients in stage IIIB/IV and 52 benign lung disease patients nutritional status were assessed according to the SGA, the scored PG-SGA, and serum albumin, prealbumin, transferrin, hemoglobin, total lymphocyte count, body mass index (BMI), and weight. A total of 40% of lung cancer patients were severely malnourished, with men or elder having a higher rate of malnutrition. Significantly lower values of weight, BMI, total lymphocyte count, transferrin, prealbumin and serum albumin were found for them. Age, sex, weight, weight half year ago and prealbumin are in the regression equation to predict them. For benign lung disease patients, 21.2% were severely malnourished with significantly lower values of weight and transferrin. Age and prealbumin are in the equation to predict severely malnourished benign lung disease patients. The highest receiver operation characteristic area under the curve was found for the PG-SGA score, BMI and weight. PG-SGA global rating, age and iron-transferring protein are in the equation for predicting disease status. The SGA and PG-SGA are appropriate for identifying malnutrition in lung disease patients. Lung cancer patients can be differentiated from benign conditions by PG-SGA.

    To demonstrate the main magnetic resonance imaging findings in patients with adnexal masses. We reviewed the images of 33 patients submitted to magnetic resonance scans of the pelvis due to suspicion of adnexal masses. Images were obtained using the following magnetic resonance imaging sequences: T1 TSE axial, T2 TSE coronal, sagittal and axial, and T 1 SPIR axial pre- and post-gadolinium injection. Among the 33 patients studied, 17 had benign ovarian masses, five had uterine tube diseases, two had sub serous myomas, one had an ectopic pregnancy, one had an embryonic cyst and one had a urachal cyst. One of the advantages of magnetic resonance imaging is multiplanar analysis that allows evaluation of the extension of the expansive adnexal lesions. The excellent contrast between structures as well as the different characteristics of the lesions in each sequence allow diagnostic precision, particularly in patients with mature cystic teratomas, endometriomas and hemorrhagic cysts.

    Benign cystic peritoneal mesothelioma is a rare tumor which frequently occurs in women of reproductive age. Abdominal pain associated with pelvic or abdominal mass is the common clinical presentation. We report the case of a 22-year-old woman with a pathological proved benign cystic mesothelioma of the peritoneum revealed by a small bowel obstruction and a painful left-sided pelvic mass with signs of psoitis. Contrast enhanced abdominal CT-scan demonstrated a large pelvic cystic mass with mass effect on rectosigmoid and pelvic organs. The patient underwent surgical removal of the tumor. Pathological examination revealed the diagnosis of benign cystic mesothelioma of the peritoneum. The outcome was excellent with a 12-month recoil.

    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.)

    Full Text Available Leiomiomatose metastatizante benigna (LMB é uma doença rara na qual o pulmão é o órgão extrauterino mais afetado. A histologia da LMB é compatível com benignidade e semelhante à encontrada nos leiomiomas miometriais. Uma história de miomatose uterina tratada cirurgicamente é relatada por quase todas as pacientes com a doença metastática. Relatamos dois casos de pacientes com leiomiomatose uterina metastatizante. No primeiro caso, uma paciente de 55 anos de idade apresentou nódulos pulmonares mais de 20 anos após ter sido submetida a uma histerectomia por leiomioma uterino. Os estudos histológico e imunoistoquímico do nódulo pulmonar revelaram tratar-se de implante de leiomioma benigno. A segunda paciente, de 65 anos de idade, apresentou nódulos pulmonares e retroperitoneais 20 anos após ter sido submetida a uma histerectomia em razão de um leiomioma uterino.Benign metastazing leiomyomatosis (BML is a rare disease in which the lung is the most affected extra-uterine organ. The BML histology is compatible with benignity and similar to that found in the myometrial leiomyoma. A history of surgically treated uterine myomatosis is reported by most of the patients with metastatic disease. We report the cases of two patients with uterine metastazing leiomyomatosis. In the first case, a 55-year-old patient presented lung nodes over 20 years after being submitted to hysterectomy due to uterine leiomyoma. The histological and immunohistochemical studies from the lung node revealed that it was an implant of benign leiomyoma. The second patient, a 65-years-old woman, presented lung and retroperitoneal nodes 20 years after being submitted to a hysterectomy due to uterine leiomyoma.

    Prostate artery embolization has garnered much attention as a promising treatment for lower urinary tract symptoms secondary to benign prostatic hyperplasia. We aim to provide an up-to-date review of this minimally invasive technique, including discussion of potential benefits and technical challenges. Current evidence suggests it is a safe and effective option for patients with medication-refractory urinary obstructive symptoms who are poor surgical candidates or refuse surgical therapy. Larger, randomized studies with long-term follow-up data are needed for this technique to be formally established in the treatment paradigm for benign prostatic hyperplasia.

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

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

    The authors have used transurethral microwave thermotherapy in the treatment of benign prostatic hyperplasia since October 1991. Irreversible cell damage occurs when the microwaves heat the periurethral prostatic tissue. The urethra is simultaneously cooled and is not destroyed during treatment. The patients are not hospitalized. Transurethral microwave thermotherapy is performed under local anaesthesia, no other form of analgesia has been found necessary. Included were patients with symptomatic prostatic obstruction who would otherwise have received operative or pharmacologic treatment. Patients with high residual urine, large middle lobe, urethral stricture, prostatic cancer, decreased renal function, urinary infection or metal implants were excluded. It was observed a marked improvement in the Madsen symptom score after transurethral microwave thermotherapy. The score decreased from 12 before treatment to five after six weeks and 4.6 after six moths. Flow increased from 8.9 to 9.7 ml/s. There was a significant reduction in the residual urine from 102 ml preoperatively to 69 ml after six months. The volume of the prostate was only slightly reduced after transurethral microwave thermotherapy. Postoperative edema caused urinary retention in 13% of the patients. Two patients required transurethral resection of the prostata. 5 refs., 3 figs., 1 tab.

    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.

    Epidemiological evidence suggests that cancers attributable to exogenous carcinogenic agents may appear decades after initiating exposures. Environmental factors including lifestyle and/or diet have been implicated in the aetiology of breast cancer. Breast tissue undergoes continuous molecular and morphological changes from the time of thelarche to menopause and thereafter. These alterations are both cyclical and longitudinal, and can be influenced by several environmental factors including exposure to oestrogens. Research into the latent period leading to breast carcinogenesis has been mostly limited to when hyperplastic lesions are present. Investigations to identify a biomarker of commitment to disease in normal breast tissue are hindered by the molecular and histological diversity of disease-free breast tissue. Benign tissue from reduction mammoplasties provides an opportunity to study biochemical differences between women of similar ages as well as alterations with advancing age. Herein, synchrotron radiation-based Fourier-transform infrared (SR-FTIR) microspectroscopy was used to examine the terminal ductal lobular epithelium (TDLU) and, intra- and inter-lobular epithelium to identify spatial and temporal changes within these areas. Principal component analysis (PCA) followed by linear discriminant analysis of mid-infrared spectra revealed unambiguous inter-individual as well as age-related differences in each histological compartment interrogated. Moreover, exploratory PCA of luminal and myoepithelial cells within the TDLU indicated the presence of specific cells, potentially stem cells. Understanding alterations within benign tissue may assist in the identification of alterations in latent pre-clinical stages of breast cancer.

    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.

Materials and Methods: The size, echogenicity, and halo integrity of 293 thyroid nodules and the presence of microcalcification in these nodules were evaluated on gray-scale examination. Doppler characteristics and elastography patterns were also evaluated and recorded. Nodules were classified in four categories (patterns 1-4 based on elastographic examination. Results: According to the cytopathological findings, 222 nodules were benign, and 71 nodules were malignant. The risk of a nodule to be malignant was 3.8 times increased by hypoechogenicity, 7.7 times increased by the presence of microcalcification, and 11.5 times increased by the absence of halo. On Doppler patterns, the presence of central vascularity increased the malignancy risk of a nodule by 5.8 times. According to the receiver operating characteristic analysis, patterns 3 and 4 were malignant, and patterns 1 and 2 were benign. The sensitivity, specificity, positive predictive value, negative predictive value, and accuracy of elastography were 100%, 80.2%, 61.7%, 100%, and 85%, respectively. Conclusion: Strain elastography can be used as a noninvasive method in distinguishing benign from malignant thyroid nodules and in identifying the patients who would undergo surgery.

    Objective To identify the predictors of massive blood transfusion in liver transplantation for patients with benign end-stage liver disease (ESLD). Methods The clinical data of 268 patients with ESLI) mainly caused by hepatitis B who were to receive cadaver liver transplantation performed by 5 groups of anesthesiologists respectively were retrospectively reviewed. The patients were divided into 2 groups according to the transfusion amount:massive blood transfusion (MBT) group (n=120) receiving the blood transfusion of more than 12 units of red blood cells (RBCs) during the operation,and non- massive blood transfusion (NBT) group (n=148). Univariate analysis and stepwise logistic regression were used. The influence of anesthesiologists on administration of blood cells was analyzed. Results During the liver transplantation, 98.13% of the patients received RBC transfusion of the mean dose of 13.32 units. Different group of anesthesiologists exerted no influence on the amount of RBC transfusion. Logistic regression showed that the preoperative MELD score, hemoglobin, platelet, interactional normalized ratio of prothrombin time, kaolin partial thromboplastin time, total protein, serum creatinine, total bilirubin, ascite, and severity of hepatitis were risk factors of MBT. Multivariable logistic regression showed that 2 independent predictors of MBT were identified: preoperative MELD score and hemoglobin. Accordingly, MBT during liver transplantation was predicted by 0.593 -0.049 × preoperative hemoglobin + 0.137 × preoperative MELD score, with a cut off value of -0.67, a sensitivity of 84.1% and a specify of 71.2%. The area under receiver operating characteristic curves of prognostic score was 0.832. Conclusion MBT during liver transplantation can be predicted by preoperative MELD score and hemoglobin value in patients with ESLD secondary to type B hepatids.%目的 分析成人良性终末期肝病肝移植受体术中发生大量输血的术前预测因子.方法

    Full Text Available The aim of this study was to assess the diagnostic values of three breast tumor markers (i.e., CEA, CA153 and CA125 in milk and nipple discharge in the prediction of different breast diseases diagnoses.Three hundred thirty-six patients (96 breast cancer and 240 benign disease patients with nipple discharge and a control group of 56 healthy parturient participants were enrolled in the present study. Nipple discharge samples were preoperatively collected from the patients, and milk was collected from the colostrum of the parturient participants. The samples were assayed for the CEA, CA153 and CA125 levels. Cutoff values were determined for the detection of breast diseases using ROC curves.The levels of CEA, CA153 and CA125 were significantly different between the nipple discharge and the milk (all ps < 0.001. In the nipple discharge, the CEA and CA153 levels in the breast cancer group were significantly greater than those in the benign group (all ps < 0.001, and cutoff values of 263.3 ng/mL and 1235.3 U/mL, respectively, were established. However, the expression of CA125 did not differ significantly between the breast cancer and benign groups.Differences in the apparent expression levels of CEA, CA153 and CA125 in patients with nipple discharge and healthy persons were validated. The present data suggest that CEA and CA153 might potentially be useful in the differential diagnoses of benign tumors and breast cancer. CA125 did not seem to be useful for breast cancer detection.

    Fungal elements are frequently noted overlying the base of chronic peptic ulcers of the stomach and it has been suggested that the fungi enhance the degree of necrosis and that these cases have protracted disease and deeper ulcers with more perforations. It has also been postulated that the number of fungal elements might be increased in the stomach of patients who are receiving potent medications such as H2-receptor antagonists to reduce gastric acidity, but there have not been adequate control studies, and the deleterious effects from the presence of the fungi in these cases have not been substantiated. We present a very rare case of invasive mucormycosis (phycomycosis) occurring in the base of a chronic gastric ulcer in a 55 years old diabetic male. This case was clinically and radiologically been mistaken for a gastric carcinoma. In addition, the ulcer was complicated by perforation and fungal septicemia with subsequent fatal outcome. The clinical, radiological and histopathological features are described together with a literature review of other reported fungal gastric ulcers.

    Bone scanning is a well-accepted and frequently performed diagnostic procedure with a high sensitivity, especially when single-photon emission tomography (SPET) acquisitions are added. However, the differentiation of benign from malignant osseous lesions often poses difficulty. The purpose of this study was to find out whether the particular localisation of an intraosseous lesion in a lumbar vertebra is an indicator of its aetiology. Bone scintigraphy including planar whole-body scans as well as SPET imaging of the lumbar spine was performed in 109 patients. The diagnoses of osseous lesions in the lumbar vertebrae were made strictly on the basis of the findings of magnetic resonance imaging, computed tomography or plain radiography. Sixteen patients had to be excluded from the study because they did not undergo adequate radiological examination. To determine the particular localisation of vertebral lesions in the bone scan, two experienced nuclear medicine physicians examined the studies independently while blinded to the radiological results. Four anatomical regions were differentiated within the vertebra: the vertebral body, the pedicle, the facet joints and the spinous process. Clopper-Pearson analysis, which takes into account the number of examinations, yielded the following probability intervals for the malignancy of intraosseous lesions in the lumbar spine: vertebral body 36.8%-57.3%, pedicle 87.7%- 100%, facet joints 0.8%-21.4% and spinous process 18.7%-81.3%. It was concluded that lesions affecting the pedicle are a strong indicator for malignancy, whereas involvement of the facet joints is usually related to benign disease. Lesions affecting the vertebral body or the spinous process do not show a clear tendency towards either malignancy or benignity. In contrast to other studies, a significant probability of malignancy (35.6%) was observed in lesions affecting exclusively the vertebral body. (orig.)

    Text mining is a flexible technology that can be applied to numerous different tasks in biology and medicine. We present a system for extracting disease-gene associations from biomedical abstracts. The system consists of a highly efficient dictionary-based tagger for named entity recognition...... of human genes and diseases, which we combine with a scoring scheme that takes into account co-occurrences both within and between sentences. We show that this approach is able to extract half of all manually curated associations with a false positive rate of only 0.16%. Nonetheless, text mining should...... not stand alone, but be combined with other types of evidence. For this reason, we have developed the DISEASES resource, which integrates the results from text mining with manually curated disease-gene associations, cancer mutation data, and genome-wide association studies from existing databases...

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

    2014-03-01

    Benign prostatic hyperplasia is a state of the nature rather than a disease. It affects mainly men over 50 years and represents a public health problem. A literature review on the therapeutic management of benign prostatic hyperplasia was carried out from a selection of publications with the highest level of evidence. Medical treatment is based on herbal medicine, alpha-blockers and 5-alpha-reductase inhibitors. Surgical treatment is used in case of complications or failure of medical management. Surgical options are numerous. Transurethral prostate resection and prostate adenomectomy are the most usual procedures. Due to their significant morbidity, other less invasive procedures have recently been developed. The choice of treatment will depend on prostate volume and anatomy and patient's comorbidities.

    2012-10-01

    We report the magnetic resonance (MR) imaging characteristics of subdural osteoma and other benign calcified intracranial lesions to highlight imaging features that differentiate between these disease entities. A 63-year-old woman presented with progressively altered mental status. Non-contrast CT demonstrated a densely calcified right middle cranial fossa extra-axial mass. MR imaging of the lesion demonstrated T1 and T2 hypointensity without evidence of contrast enhancement, parenchymal abnormality, or connection to adjacent venous structures. Diffusion weighted imaging demonstrated markedly decreased signal intensity and artificially reduced diffusion on apparent diffusion coefficient map. Histologically, the tumor was predominantly composed of lamellar bone and small fragments of residual dura consistent with subdural osteoma. This case demonstrates that radiological examination can provide additional insight into the origin of intracranial osteomas (extradural versus subdural versus sinonasal) and help distinguish from other diagnostic considerations including benign meningeal ossification and calcified meningioma prior to surgical resection.

    This paper deals with application of fuzzy intelligent systems in diagnosing severity level and recommending appropriate therapies for patients having Benign Prostatic Hyperplasia. Such an intelligent system can have remarkable impacts on correct diagnosis of the disease and reducing risk of mortality. This system captures various factors from the patients using two modules. The first module determines severity level of the Benign Prostatic Hyperplasia and the second module, which is a decision making unit, obtains output of the first module accompanied by some external knowledge and makes an appropriate treatment decision based on its ontology model and a fuzzy type-1 system. In order to validate efficiency and accuracy of the developed system, a case study is conducted by 44 participants. Then the results are compared with the recommendations of a panel of experts on the experimental data. Then precision and accuracy of the results were investigated based on a statistical analysis.

    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.)

    Background. Primary sclerosing cholangitis (PSC) is a chronic inflammatory liver disease and is strongly associated with cholangiocarcinoma (CCA). The lack of efficient diagnostic methods for CCA is a major problem. Testing for genetic abnormalities may increase the diagnostic value of cytology. Methods. We assessed genetic abnormalities for CDKN2A, TP53, ERBB2, 20q, MYC, and chromosomes 7 and 17 and measures of genetic clonal diversity in brush samples from 29 PSC patients with benign biliary strictures and 12 patients with sporadic CCA or PSC-associated CCA. Diagnostic performance of cytology alone and in combination with genetic markers was evaluated by sensitivity, specificity, and area under the curve analysis. Results. The presence of MYC gain and CDKN2A loss as well as a higher clonal diversity was significantly associated with malignancy. MYC gain increased the sensitivity of cytology from 50% to 83%. However, the specificity decreased from 97% to 76%. The diagnostic accuracy of the best performing measures of clonal diversity was similar to the combination of cytology and MYC. Adding CDKN2A loss to the panel had no additional benefit. Conclusion. Evaluation of MYC abnormalities and measures of clonal diversity in brush cytology specimens may be of clinical value in distinguishing CCA from benign biliary strictures in PSC. PMID:27127503

    18F-Fluoro-deoxyglucose positron emission computed tomography (FDG-PET/CT) is an emerging diagnostic imaging modality in veterinary medicine; however, little published information is available on physiologic variants, benign processes, and artifacts. The purpose of this retrospective study was to describe the number of occurrences of non-neoplastic disease-related FDG-PET/CT lesions in a group of dogs and cats. Archived FDG-PET/CT scans were retrieved and interpreted based on a consensus opinion of two board-certified veterinary radiologists. Non-neoplastic disease-related lesions were categorized as physiologic variant, benign activity, or equipment/technology related artifact. If the exact cause of hypermetabolic areas could not be determined, lesions were put into an indeterminate category. A total of 106 canine and feline FDG-PET/CT scans were included in the study. In 104 of the 106 scans, a total of 718 occurrences of physiologic variant, areas of incidental benign activity, and artifacts were identified. Twenty-two of 23 feline scans and 82 of 83 canine scans had at least one artifact. Previously unreported areas of increased radiopharmaceutical uptake included foci associated with the canine gall bladder, linear uptake along the canine mandible, and focal uptake in the gastrointestinal tract. Benign activity was often seen and related to healing, inflammation, and indwelling implants. Artifacts were most often related to injection or misregistration. Further experience in recognizing the common veterinary FDG physiologic variation, incidental radiopharmaceutical uptake, and artifacts is important to avoid misinterpretation and false-positive diagnoses.

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

    Full Text Available The aim of our study was to assess the outcome of treatment of horizontal canal benign paroxysmal positional vertigo and to analyze the influence of the different prognostic factors on treatment failure. Fifty-nine patients with horizontal canal benign paroxysmal positional vertigo were included in the study. They were divided into two groups according to the treatment protocol, randomly. The first group, after treatment with the barbecue maneuver or inverted Gufoni, depending on the nystagmus form, was instructed to sleep on the side with weaker nystagmus, and the second group did not. In the first group, 88.9% of patients were cured and 91.3% in the second one. There was no significant difference between the two groups. Migraine and the apogeotropic form of nystagmus had a significant effect on treatment outcome, while other variables had no effect.

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

    Radiofrequency ablation (RFA) enables the ablation of selected tissue by means of heat. For the first time in the Netherlands, RFA is being used to treat patients with benign thyroid nodules. RFA is able to reduce the volume of a nodule that may be causing cosmetic complaints or problems due to mass effect. This avoids the need for surgery or treatment with radioactive iodine in this benign condition. The average reduction in size is 80% in the first year, leading to a considerable decrease in both symptomatic and cosmetic complaints. At Erasmus Medical Centre, Rotterdam, the Netherlands, this technique has been introduced in accordance with current guidelines, and it is expected that other centres of excellence will follow in implementing it. It is important that the initial experiences with this technique in the Netherlands in terms of effectiveness, risks and patient satisfaction should be monitored before RFA becomes routine treatment.

    2015-01-01

    Full Text Available With increased exposure of patients to routine imaging, incidental benign intrathoracic masses are frequently recognized. Most have classical imaging features, which are pathognomonic for their benignity. The aim of this pictorial review is to educate the reader of radiological features of several types of intrathoracic masses. The masses are categorized based on their location/origin and are grouped into parenchymal, pleural, mediastinal, or bronchial. Thoracic wall masses that invade the thorax such as neurofibromas and lipomas are included as they may mimic intrathoracic masses. All examples are illustrated and include pulmonary hamartoma, pleural fibroma, sarcoidosis, bronchial carcinoid, and bronchoceles together with a variety of mediastinal cysts on plain radiographs, computed tomography (CT and magnetic resonance imaging (MRI. Sometimes a multimodality approach would be needed to confirm the diagnosis in atypical cases. The study would include the incorporation of radionuclide studies and relevant discussion in a multidisciplinary setting.

    Full Text Available Benign prostate hypertrophy (BPH is the most common benign tumor in men due to obstruction of the urethra and, finally, uremia. Malondialdehyde (MDA is a product derived from peroxidation of polyunsaturated fatty acids and related esters. Evaluation of MDA in serum represents a non-invasive biomarker of oxidative stress. Prostate-specific antigen (PSA is a sensitive marker for prostatic hypertrophy and cancer. We analyzed MDA serum levels to evaluate the oxidative stress in BPH. To this end, 22 BPH patients and 22 healthy donors were enrolled. Data show an increase of MDA level in BPH patients and a positive correlation between PSA and MDA levels. In conclusion, we describe a previously unknown relationship between PSA and MDA as an index of inflammation and oxidative stress in BPH.

    Woodard, Todd J; Manigault, Kendra R; McBurrows, Niesha N; Wray, Tiffany L; Woodard, Laresa M

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

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

    Benign recurrent abducens (6th) nerve palsy is rare. We found 23 cases in children reported in the literature; however, many of these cases followed immunization or were associated with viral illness. Here we report two cases of recurrent abducens nerve palsy with no obvious etiology. The diagnosis should be considered in any child who experiences abducens nerve palsy in the absence of any underlying pathology or precipitating factors.

    Rupture of benign thyroid tumors after RFA is very rare. We experienced 6 cases in 4 institutions. All patients presented with abrupt neck swelling and pain between 9 and 60 days after RFA. Imaging and clinical findings of the ruptured tumors were anterior subcapsular location, mixed composition, large size, and repeated ablations. Conservative treatment was sufficient in 3 cases, whereas surgical management was required in 3.

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

    AIM To analyze retrospectively a 5-year experience of human hepatocyte isolation from resected liver tissues with benign disease. METHODS We established a method of modified four-step retrograde perfusion to isolate primary human hepatocytes. Samples were collected from the resected livers of patients with intrahepatic duct calculi (n = 7) and liver hemangioma (n = 17). Only the samples weighing ≥ 15 g were considered suitable for hepatocyte isolation. By using the standard trypan blue exclusion technique, hepatocyte viability and yield were immediately determined after isolation. RESULTS Twenty-four liver specimens, weighing 15-42 g, were immediately taken from the margin of the removed samples and transferred to the laboratory for hepatocyte isolation. Warm ischemia time was 5-35 min and cold ischemia time was 15-45 min. For the 7 samples of intrahepatic duct calculi, the method resulted in a hepatocyte yield of 3.49 ± 2.31 × 106 hepatocytes/g liver, with 76.4% ± 10.7% viability. The 17 samples of liver hemangioma had significantly higher yield of cells (5.4 ± 1.71 × 106 cells/g vs 3.49 ± 2.31 × 106 cells/g, P 0.05). We obtained a cell yield of 5.31 ± 1.87 × 106 hepatocytes/g liver when the samples weighed > 20 g. However, for the tissues weighing ≤ 20 g, a reduction in yield was found (3.08 ± 1.86 × 106 cells/g vs 5.31 ± 1.87 × 106 cells/g, P < 0.05). CONCLUSION Benign diseased livers are valuable sources for large-number hepatocyte isolation. Our study represents the largest number of primary human hepatocytes isolated from resected specimens from patients with benign liver disease. We evaluated the effect of donor liver characteristics on cell isolation, and we found that samples of liver hemangioma can provide better results than intrahepatic duct calculi, in terms of cell yield. Furthermore, the size of the tissues can affect the outcome of hepatocyte isolation. PMID:27688659

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

    We have applied infrared microspectroscopic imaging for the examination of benign breast tumor tissue sections. The IR spectra of the sections were obtained by classical point microscopy with a movable stage and via a microscope equipped with a focal plane array detector. The infrared microscopic data were analysed using functional group mapping techniques and cluster analysis. The output values of the two procedures were reassembled into infrared images of the tissues, and were compared with standard staining images of the corresponding tissue region. The comparative examination of identical tissue sections by the two IR approaches enabled us to assess potential problems associated with tissue microheterogeneity. It was found that in case of fibroadenoma, a benign lesion located in breast ducts, point microscopy with a spot size of ˜30 μm is a useful practical approach which minimizes the possibility of 'contamination' of the spectra because of spectral averaging of all tissue components present in the corresponding microareas. A comparison of the spectra of the benign breast tumor with those of a malignant ductal carcinoma in situ revealed that IR microspectroscopy has the potential to differentiate between these two breast tumor types.

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

    A prospective study was undertaken to evaluate the changes in portal venous pressure in patients with benign biliary obstruction (BBO) but without overt clinical, endoscopic or radiological evidence of portal hypertension. Portal venous pressure was measured at laparotomy in 20 patients (10 each with either benign biliary stricture or choledocholithiasis) before and after biliary decompression. Pressure was found to be on the high side in seven patients (>25 cm of saline in three patients and > 30 cm of saline in four). The mean fall of pressure was 3.4 cm of saline after biliary decompression. No correlation could, however, be found between portal venous pressure and duration of biliary obstruction, serum bilirubin or bile duct pressure. Liver histology showed mild to moderate cholestatic changes but maintained portal architecture in all. Benign biliary obstruction may therefore, lead to elevation of portal pressure, even though the patient may not necessarily have any clinical, endoscopic or radiological manifestations of portal hypertension. The pathogenesis of this ‘latent’ portal hypertension is probably multifactorial. If biliary obstruction is left untreated the development of overt portal hypertension may become a possibility in the future. PMID:8725455

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

    Benign multicystic mesothelioma is a rare tumour that originates from the abdominal peritoneum with a predisposition to the pelvic peritoneum. It typically affects women of reproductive age. There have been less than 200 cases of this rare neoplasia reported to date. We present the case of a 35-year-old woman who was referred to our centre because of the detection of a peritoneal carcinomatosis during a gynaecological exam. A diagnostic laparoscopy was performed. The findings included multiple cysts appearing as 'a bunch of grapes' occupying the omentum. Biopsies were taken during the surgery and the results showed benign multicystic peritoneal mesothelioma. Benign multicystic mesothelioma can simulate other conditions, such as malignant ovarian tumours or cystic lymphangioma. It is often diagnosed accidentally during surgery performed for another reason. The diagnosis is interoperative, observing multicystic structures grouped as a 'bunch of grapes' containing clear fluid with thin walls made of connective tissue. Immunohistochemistry confirmed mesothelial origin. Surgery is considered the treatment of choice and is based on the removal of the cysts from the abdominal cavity. Hyperthermic intraperitoneal chemotherapy can be considered as a primary treatment in patients with recurrences or even as a part of primary treatment associated with surgery. Survival at 5 years is 100% and invasive or malignant progression is extraordinary. The treatment approach should be multidisciplinary, and the patient should be referred to a referral centre.

    Full Text Available Positional vertigo is a common neurologic emergency and mostly the etiology is peripheral. However, central diseases may mimic peripheral positional vertigo at their initial presentation. We here describe the results of a visual suppression test in six patients with spinocerebellar ataxia type 6 (SCA6, a central positional vertigo, and nine patients with benign paroxysmal positional vertigo (BPPV, the major peripheral positional vertigo. As a result, the visual suppression value of both diseases differed significantly; e.g., 22.5% in SCA6 and 64.3% in BPPV (p < 0.001. There was a positive correlation between the visual suppression value and disease duration, cerebellar atrophy, and CAG repeat length of SCA6 but they were not statistically significant. In conclusion, the present study showed for the first time that visual suppression is impaired in SCA6, a central positional vertigo, but preserved in BPPV, the major peripheral positional vertigo, by directly comparing both groups. The abnormality in the SCA6 group presumably reflects dysfunction in the central visual fixation pathway at the cerebellar flocculus and nodulus. This simple test might aid differential diagnosis of peripheral and central positional vertigo at the earlier stage of disease.disease.

    2010-04-01

    Benign prostatic hyperplasia (BPH) is a world-wide common disease in elderly male patients. A number of invasive physiotherapies have been used to replace prostatectomy. In this article we report our hypothesis of using microbubbles-mediated ultrasound cavitation effects to ablate prostatic tissues. Microbubble ultrasound contrast agent is widely used contrast media in ultrasonography, yet it is also found to act as cavitation nuclei or enhancer. Once excited by a high peak pressure ultrasound pulse, the mechanical effects, like shock wave and microstream, released from cavitation could produce a series of bioeffects, contributing to sonoporation, microvascular rupture and hematoma. BPH is known to have hyperplastic neovasculature and this make it possible to be disrupted by the physical effects of cavitation under existing microbubbles in circulation. Mechanical ablation of prostatic capillary or small vessels could result in pathological alterations such as thrombosis, micro-circulation blockage, prostatic necrosis and atrophia. Thereupon it could effectively treat BPH by nontraumatic ways.

    Synchronous tumors of the female genital tract are rare, accounting for 0.7-1.8% of all cases. Double synchronous tumors are most often mentioned in the literature. Reviewing the English literature on this topic, we have found only one case report of a triple synchronous tumor. The 55-year-old patient mentioned in our case has had advanced diabetes mellitus, and has been treated with corticosteroid therapy for a long time because of chronic obstructive pulmonary disease (COPD). She was examined because of her vulvar tumor. During the diagnostic procedure, cervical and endometrial malignant tumors and a benign ovarian cyst have also been found. This event brings to our attention the fact that we should be prepared to manage synchronous even triple malignant gynecological tumors.

    Full Text Available Benign tumors are affecting the proximal part of the femur in 19% of all cases. Their distinctive feature is the relatively late diagnosis, which requiring the necessity, in addition to removing the tumor and bone grafting, to solve the problem of deformations correction. We have discovered the reasons of deformity appearance of the 31 patients aged 3-16 years. The following types of deformation were defined: ductile (12, after pathological fracture (12 and as a result of growth plate dysfunction (7. The correction of deformation, along with the tumour removing was performed at 15 patients: 3 - Oilier disease, 6 - fibrous dysplasia, 4 - bone cysts, 2 - exostotic chondrodysplasia. In 2 cases the correction of deformity was supposed unreasonable by its severity and accompanying pathology, and in 14 - the deformities were considered as permissible, that not required operative adjustment.

    As fistula occurring between the stomach and other abdominal internal organs or to the surface of the body is usually encountered as a complication of stomach cancer or colon cancer, peptic ulcer disease, or other variable causes. The most common type of gastric fistula is a gastro-colic fistula that is mainly found as a complication of a gastric carcinoma or of a carcinoma of the transverse colon invading each other. Sometimes, a benign gastric ulcer perforation also can cause a gastro-colic fistula. However, as far as we know, a fistula occurring between the stomach and the umbilicus has not been reported. Here we present a case report of a gastro-umbilical fistula in a young woman that manifested as a umbilical discharge.

    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.

    Excessive and repetitive force applied on vocal fold tissue can induce benign vocal fold lesions. Children affected suffer from chronic hoarseness. In this instance, the vibratory ability of the folds, a complex layered microanatomy, becomes impaired. Histological findings have shown that lesions produce a remodeling of sup-epithelial vocal fold layers. However, our understanding of lesion features and development is still limited. Indeed, conventional imaging techniques do not allow a non-invasive assessment of sub-epithelial integrity of the vocal fold. Furthermore, it remains challenging to differentiate these sub-epithelial lesions (such as bilateral nodules, polyps and cysts) from a clinical perspective, as their outer surfaces are relatively similar. As treatment strategy differs for each lesion type, it is critical to efficiently differentiate sub-epithelial alterations involved in benign lesions. In this study, we developed an optical coherence tomography (OCT) based handheld probe suitable for pediatric laryngological imaging. The probe allows for rapid three-dimensional imaging of vocal fold lesions. The system is adapted to allow for high-resolution intra-operative imaging. We imaged 20 patients undergoing direct laryngoscopy during which we looked at different benign pediatric pathologies such as bilateral nodules, cysts and laryngeal papillomatosis and compared them to healthy tissue. We qualitatively and quantitatively characterized laryngeal pathologies and demonstrated the added advantage of using 3D OCT imaging for lesion discrimination and margin assessment. OCT evaluation of the integrity of the vocal cord could yield to a better pediatric management of laryngeal diseases.

    Aim: To investigate the diagnostic and differential diagnostic values of dynamic contrast-enhanced magnetic resonance imaging (DCE MRI) in prostatic diseases, and to investigate the correlation between the parameters of SI-T curves and angiogenesis. Materials and methods: Twenty-one patients with proven prostatic carcinoma (Pca) and 29 patients with proven benign prostatic hyperplasia (BPH) were examined using DCE MRI. Diagnostic characteristics for differentiation were examined using threshold values for maximum peak time, enhancement degree, and enhancement rate. Then, the signal intensity-time curves (SI-T curves) were analysed, and the correlations between the parameters of SI-T curves and the expression levels of vascular endothelial growth factor (VEGF) and microvascular density (MVD) were investigated. All patients underwent prostatectomy. DCE MRI and histological findings were correlated. Results: Pca showed stronger enhancement with an earlier peak time, higher enhancement, and enhancement rate (p < 0.05). Regarding the type of SI-T curves, in the BPH group six were type A, 10 were type B, and 13 were type C, whereas in the Pca group, 14 were type A, six were type B, and only one was type C (Chi-square test, {chi}{sup 2} = 13.57, P < 0.005). The VEGF and MVD expression levels of Pca were higher than those of BPH. Peak time was negatively correlated with the expression levels of VEGF and MVD, whereas the enhancement degree and enhancement rate showed positive correlations (Pearson correlation, p < 0.05). Conclusion: Based on T2-weighted imaging, DCE MRI curves can help to differentiate benign from malignant prostate tissue. In the present study the type C curve was rarely seen with malignant disease, but these results need confirmation.

    The present study was aimed at describing key computed tomography and magnetic resonance imaging findings in patients with acute abdominal pain derived from pelvic inflammatory disease. Two radiologists consensually selected and analyzed computed tomography and magnetic resonance imaging studies performed between January 2010 and December 2011 in patients with proven pelvic inflammatory disease leading to presentation of acute abdomen. Main findings included presence of intracavitary fluid collections, anomalous enhancement of the pelvic excavation and densification of adnexal fat planes. Pelvic inflammatory disease is one of the leading causes of abdominal pain in women of childbearing age and it has been increasingly been diagnosed by means of computed tomography and magnetic resonance imaging supplementing the role of ultrasonography. It is crucial that radiologists become familiar with the main sectional imaging findings in the diagnosis of this common cause of acute abdomen (author)

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

    Simple esophageal strictures, which are focal, straight, and large in diameter, usually require 1 - 3 dilation sessions to relieve symptoms. However, complex strictures, which are long, tortuous, or associated with a severely compromised luminal diameter, are usually more difficult to treat with conventional bougie or balloon dilation techniques, and often have high recurrence rates. Although the permanent placement of self-expandable metal stents (SEMS) has been used to manage refractory benign esophageal strictures, this procedure is associated with additional problems, such as stricture from tissue hyperplasia, stent migration, and fistula formation. Thus, several new types of stents have been developed, including temporary SEMS, self-expandable plastic stents (SEPS), and biodegradable stents. The use of these new products has produced varied results. Temporary SEMS that have been used to relieve benign esophageal conditions have caused granulation tissue at both ends of the stent because of contact between the mucosa and the exposed metal components of the stent, thus hindering stent removal. We examined the tissue response to two new types of SEMS, a flange-type and a straighttype, each coated with a silicone membrane on the outside of the metal mesh. These two SEMS were evaluated individually and compared with a conventional control stent in animal experiments. Although the newly designed stents resulted in reduced tissue hyperplasia, and were thus more easily separated from the esophageal tissue, some degree of tissue hyperplasia did occur. We suggest that newly designed DES (drug-eluting stents) may provide an alternative tool to manage refractory benign esophageal stricture.
