Obesity can predispose women to pelvic organ prolapse and can also affect the success of pelvic organ prolapse surgery. The purpose of this study was to compare the postoperative anatomical outcomes following sacral colpopexy (SC) and transvaginal mesh colpopexy in a group of obese women with pelvic organ prolapse. We conducted a retrospective cohort study of obese women who underwent SC (n = 56) or transvaginal mesh colpopexy (n = 35). Follow-up ranged from 6 to 12 months. Preoperative, perioperative, and postoperative variables were compared using Student t, Mann-Whitney U, and Fisher exact tests, and by analysis of covariance. The women in the SC group had significantly higher mean apical vaginal measurements (P transvaginal mesh colpopexy group. There were no significant differences between the groups for other postoperative outcomes, including mesh erosion, recurrent prolapse symptoms, dyspareunia, and surgical satisfaction (P > 0.05). In these 91 obese patients with pelvic organ prolapse, SC resulted in better anatomical outcomes than transvaginal mesh colpopexy. However, the two procedures had similar outcomes with regard to recurrent symptoms and surgical satisfaction.

INTRODUCTION: Despite several benefits, patients are concerned that transvaginal cholecystectomy has a negative impact on sexual health. The objective of this systematic review was to assess the impact of transvaginal cholecystectomy on postoperative dyspareunia and sexual function. METHOD......: A literature search was performed in the PubMed and EMBASE databases. Papers reporting on postoperative dyspareunia, vaginal pain or discomfort, and sexual function were included. RESULTS: Seventeen papers reported on dyspareunia and vaginal pain or discomfort. Two papers reported a rate of de novo dyspareunia...... of 3.8% and 12.5%, respectively. One study reported a nonsignificant reduction in painful sexual intercourse and the remaining 14 reported no incidents of dyspareunia. Eight papers reported on sexual function. One paper using a nonvalidated questionnaire found impaired sexual function. The papers...

Uterine-sparing procedures could be attractive in patients concerned about preservation of fertility and change in corporeal image and sexuality. Transvaginal uterosacral hysteropexy can provide an alternative mesh-free technique for uterine suspension. This study aimed to evaluate the feasibility of transvaginal uterine suspension to uterosacral ligaments in terms of operative data, complications, midterm efficacy, and patient satisfaction. This retrospective study analyzed the first 20 cases of transvaginal hysteropexy through bilateral high uterosacral ligaments (modified Shull technique) performed in our Institution. Mean follow-up was 33.2 months. The procedure was performed in 84 ± 19 min ,and blood loss was 228 ± 139 ml. Three mild complications (15 %) were observed. Recurrence [Pelvic Organ Prolapse Quantification system (POP-Q) stage ≥ II was observed in five patients (25 %), and three of them (15 %) required reintervention. Mean Patient Global Impression of Improvement score was "much improved." Two woman (40 %) who had not fulfilled their childbearing desire obtained a pregnancy. Both underwent elective caesarean section at term. Transvaginal uterosacral hysteropexy appears a feasible mesh-free technique for apical support. This procedure can be indicated in women with the desire of preserving fertility or who prefer a uterine-sparing surgical option.

Full Text Available Background: Abnormal uterine bleeding (AUB is one of the most common clinical problemsin gynecology. Transvaginal sonography (TVS and hysteroscopy are two diagnostic methods forpatients with AUB. For most of the patients with AUB, diagnostic hysteroscopy can be done inclinic with minimal discomfort and much lower expense than operative room.Materials and Methods: In our clinical trial study, from March 21, 2005 to March 20, 2007,patients with AUB in Ahwaz Imam Khomayni hospital, after history and physical examinationsunderwent TVS. Of those, 147 patients with normal TVS entered the study and were considered foroutpatient hysteroscopy. Patients with endometrial cavity lesion were scheduled for operation room,and those with empty endometrial cavity aspiration biopsy were done outpatiently. Specimens weresent to pathologist for examination.Results: All the patients were divided into three groups: group 1 or minority was under 30 yearsold (7 women, group 2 was 30-40 years, and group 3 or majority was over 40 years old (96women. 115 patients (78.2% had normal and 32 patients (21.8% had abnormal hysteroscopicresults. 116 patients (78.8% had normal and 31 patients (21.2% had abnormal pathologic results;moreover, cervical canal polyp was the most common lesion hysteroscopically and pathologicallyin all groups.Conclusion: Of 147 patients (100% with AUB and normal TVS, 32 patients (21.8% wereabnormal hysteroscopically. Cervical canal polyps may be missed by transvaginal sonography, butcan be diagnosed by hysteroscopy. In patients with AUB and normal TVS, hysteroscopy can beused as the second step.

To determine whether transvaginal ultrasound criteria alone can distinguish viable from non-viable gestational sacs at a single examination. A prospective descriptive study was undertaken and analysis performed on 211 pregnancies complicated by threatened abortion and empty gestation sacs diagnosed by transvaginal ultrasound. The main outcome measure was the final diagnosis of viable or non-viable gestation on subsequent transvaginal sonography. The study shows that a single transvaginal ultrasound examination is useful in differentiating viable from non-viable gestation sacs. The mean sac diameter (MSD) was found to be the most useful criterion for determining non-viability. An MSD of > or = 17 mm that lacked an embryo and an MSD of > or = 13 mm without visible yolk sac were reliable predictors of non-viable gestation sacs at a single examination with 100% specificity and 100% positive predictive value. An MSD > or = 13 mm without visible yolk sac was the most sensitive criterion. Using MSD criteria, 73% of non-viable gestations could be reliably identified without any false-positive diagnoses. Deformed shape, low position and thin decidual reaction are strong indicators of non-viable gestations but are not 100% accurate. There is still a significant proportion of empty sacs, where no accurate distinction between viable and non-viable can be made according to one criterion at a single examination and in these cases serial examinations should be carried out before any active management is advocated. In most cases, transvaginal sonographic criteria alone can distinguish viable from non-viable empty gestational sacs at a single examination.

The goal of this study was to assess the clinicopathologic and ultrasonographic features of thyroid nodules with nondiagnostic results on repeat ultrasonography (US)-guided fineneedle aspiration biopsy (FNAB) according to size and the number of suspicious findings and to determine the proper management of nodules with consecutive nondiagnostic results. This retrospective study included 297 nodules with nondiagnostic results on repeat FNAB that were evaluated by US over the course of at least 12 months of follow-up, a follow-up biopsy, or an operation. We compared clinical and US variables between benign and malignant nodules in thyroid nodules with repeat nondiagnostic results. The comparison of benign and malignant nodules with repeat nondiagnostic results revealed that age, marked hypoechogenicity, irregular or microlobulated margins, microcalcifications, and nonparallel shape were significantly associated with malignancy. Multivariate logistic regression analysis in malignant nodules revealed that microcalcifications and irregular or microlobulated margins were independently associated with malignancy. Among them, only irregular or microlobulated margins were independently significant as a predictor of malignancy in repeatedly nondiagnostic nodules measuring >10 mm. Using receiver operating characteristic analysis, the best cutoff value for the “number of suspicious findings” between benign and malignant nodules was three in nodules of all sizes, three in nodules measuring ≤10 mm, and two in nodules measuring >10 mm. Irregular or microlobulated margins may be the most frequent US features in repeatedly nondiagnostic nodules >10 mm. The presence of “two or more suspicious findings” can be used as the cutoff for distinguishing benign and malignant nodules.

To assess the suitability of transvaginal duplex ultrasonography to identify pathological reflux in the ovarian and internal iliac veins in women. A retrospective study of patients treated in 2011 and 2012 was performed in a specialised vein clinic. Diagnostic transvaginal duplex ultrasonography in women presenting with symptoms or signs of pelvic vein reflux were compared with the outcomes of treatment from pelvic vein embolisation. A repeat transvaginal duplex ultrasonography was performed 6 weeks later by a blinded observer and any residual reflux was identified. Results from 100 sequential patients were analysed. Mean age 44.2 years (32-69) with mode average parity of 3 (0-5 deliveries). Pre-treatment, 289/400 veins were refluxing (ovarian - 29 right, 81 left; internal iliac - 93 right, 86 left). Coil embolisation was successful in 86/100 patients and failed partially in 14/100 - 5 due to failure to cannulate the target vein. One false-positive diagnosis was made. Currently there is no accepted gold standard for pelvic vein incompetence. Comparing transvaginal duplex ultrasonography with the outcome from selectively treating the veins identified as having pathological reflux with coil embolisation, there were no false-negative diagnoses and only one false-positive. This study suggests that transvaginal duplex ultrasonography could be the gold standard in assessing pelvic vein reflux. © The Author(s) 2014.

Natural orifice transluminal endoscopic surgery procedures have evolved over the past few years. A transvaginal approach is a promising alternative for intraperitoneal procedures. Our objective was to evaluate the safety and feasibility of transvaginal organ extraction. This institutional review board-approved protocol involved retrospective review of an ongoing prospective study. Female subjects who presented to our hospital for elective cholecystectomy, appendectomy, or sleeve gastrectomy were offered participation in the study. Eligible patients met the following criteria: age between 18 and 75, diagnosis of gallbladder disease, acute appendicitis, or morbid obesity who desired surgical treatment. A hybrid transvaginal natural orifice approach was used in this series. Thirty-four women underwent transvaginal organ extraction between September 2007 and January 2012. The mean age was 40 ± 12.1 years (range 23-63 years). The mean body mass index was 27 ± 6.4 kg/m(2) (range 16-43 kg/m(2)). All patients had an American Society of Anesthesiologists classification of two or below. The mean operative time for cholecystectomy, appendectomy, and sleeve gastrectomy was 90, 71, and 135 min, respectively. There were no conversions to open operation and no intraoperative complications. The mean hospital stay was 2 days for all cases. Patients were followed for a mean of 24 months (range 1-61 months). There were two pregnancies and two successful vaginal deliveries. Six patients (18 %) had minor complaints of spotting or heavy menses in the immediate postoperative period that resolved with conservative measures. There were no abdominal wall complications. There were no long-term complications and no mortalities. This initial experience suggests that this surgical approach is safe, does not increase length of stay, and has no long-term vaginal complications. Given this attractive profile, a transvaginal approach may prove to be a superior mode of organ extraction

To determine the value of transvaginal sonography in evaluating women with acute pelvic inflammatory disease (PID). Transvaginal sonography was performed in 25 patients with clinically suggested PID during recent 36 months. The sonographic findings of fallopian tubes and ovaries were analyzed and correlated with pathological findings of 2 fallopian tubes and 19 ovaries in 16 patients who had operations. The correct diagnosis of acute PID was made in 20/25 (80%) by transvaginal sonography. the abnormal sonographic findings of the fallopian tube include tubal thickening or dilatation with internal echo. The sensitivity, specificity, and accuracy for tubal abnormality were 88%, 96%, and 86% , respectively. Ovarian changes were seen on TVS in 14/19 (73%), which include multiple follicular enlargement in 5, tubo-ovarian complex in 9 (tubo-ovarian adhesion in 3, tubo-ovarian abscess in 6). At surgery, the ovay was not involved in all three women who showed tubo-ovarian adhesion on TVS. Among 6 women who showed tubo-ovarian abscess on TVS, tubo-ovarian abscess was confirmed in 3 and the remaining 3 had ovarian cysts. Trandvaginal sonography, a facilitative and accurate modality, is highly sensitive in detecting the abnormality of the tube and useful in differentiating the tubo-ovarian complex in patients with acute PID.

Ovarian endometrioma often present with inhomogeneous ultrasound patterns. The differentiation to other ovarian tumors could be difficult. In case of primary diagnosis, histological findings are indicated, all the more as ovarian endometriosis has an increased risk for malignant transformation. Therapeutic surgical intervention should be done in sano.brNevertheless, to affect a compromise in case of infertility, especially in patients with reduced ovarian reserve, laparoscopic aspiration or laser coagulation after fenestration could be a second option with the occurrence of small recurrent endometriomas. A histological diagnosis should be done, too. The surgical procedure should be discussed with the department of reproductive medicine.brThe effect of endometriomas on the reproductive outcome is not clear. Systematic reviews have shown that regarding pregnancy rates, endometriomas do not have to be necessarily removed. Primary ultrasound-guided transvaginal aspiration of endometriomas should be avoided to decrease the risk of infection. If the same is the truth in case of accidental aspiration during the oocyte retrieval, remains unproven.

Full Text Available Background: Combined abdominal and transvaginal anterior perineal approaches have been used as an alternative surgical method for the surgical treatment of the lower rectal cancer. The main aim of this paper is to describe the surgical stages of the combined abdominal and transvaginal approaches performed for lower rectal cancer, especially in transvaginal anterior perineal stage. Method: We have performed sphincter-saving surgical operations by using transvaginal anterior perineal access by combining with the abdominal access in four female patients who had lower rectal cancer. Results: Sphincter-saving extrasphincteric dissection and proximal segmental sphincteric excision techniques were performed in four female patients operated with combined abdominal and transvaginal anterior perineal approach. All patients were found to have continence. Postoperatively, one patient was converted to abdominoperineal rectal amputation due to the detected distal resection margin positivity. Conclusion: Transvaginal anterior perineal access provides the extrasphincteric rectal dissection possibility in the ischioanal fossa. Therefore, the combined abdominal and transvaginal anterior perineal approaches have been based on the different anatomical and surgical features when compared to intersphincteric dissection technique which is the most common used surgical procedure in lower rectal cancer surgery.

Transvaginal ultrasound is the first-line imaging test for the evaluation of abnormal uterine bleeding in both premenopausal and postmenopausal women. Transvaginal ultrasound can be used to diagnose structural causes of abnormal bleeding such as polyps, adenomyosis, leiomyomas, hyperplasia, and malignancy, and can also be beneficial in making the diagnosis of ovulatory dysfunction. Traditional 2-dimensional imaging is often enhanced by the addition of 3-dimension imaging with coronal reconstruction and saline infusion sonohysterography. In this article we discuss specific ultrasound findings and technical considerations useful in the diagnosis of abnormal uterine bleeding.

Full Text Available Fine needle aspiration biopsy (FNA is the only diagnostic method that allows a preoperative diagnosis of thyroid carcinoma. An unequivocal diagnosis of a malignant change is achievable only in cases in which all cytological criteria of carcinoma are met. The aim of the study was to evaluate the necessity of repeat thyroid FNA in patients with papillary thyroid carcinoma verified on consultative examination (CE. We analyzed cytology reports of thyroid FNA and CE that resulted in the diagnosis of papillary carcinoma. Evaluation of the correlation of the cytological diagnosis with the histopathology report was based on data obtained after the surgery. Between 2010 and 2015 in the Institute of Oncology (IO there were 184 cancers diagnosed on CE or in thyroid FNA performed primarily in IO. Additionally, 74 patients were subjected to repeat biopsy after confirmation of cancer in CE. Histopathological diagnosis of cancer was obtained in 62 (100% cases that were doubly confirmed with cytological examination. The remaining 12 patients were operated on outside the institute. From 110 FNA primarily performed in the IO, histopathological verification was achievable in 92 cases, from which 92 (100% provided a confirmation of cancer, and the remaining 18 patients were operated on outside the institute. High (100% specificity of cancer diagnosis in FNA established primarily and verified on CE (second independent assessment indicates that repeat FNA in order to confirm the diagnosis is unnecessary.

Between January and December 2010, women with post-hysterectomy recurrent prolapse (≥ stage 2 POP-Q) after transvaginal polypropylene mesh prolapse surgery were included. Perioperative morbidity and short-term complications were recorded and evaluated. Surgical outcomes were objectively assessed utilising the Pelvic Organ Prolapse Quantification system (POP-Q), the validated, condition-specific Australian Pelvic Floor Questionnaire (APFQ) and the Patient Global Impression of Improvement (PGI-I) at 12 months. All 16 women in this study had undergone surgery with trocar-guided transvaginal polypropylene mesh kits. In 75% the recurrent prolapse affected the compartment of prior mesh surgery with the anterior (81%) and apical (75%) compartment prolapse predominating. At a mean follow-up of 12 months, all women had resolution of awareness of prolapse, had transvaginal mesh surgery is feasible and safe. Further widespread evaluation is required.

Treatment of pelvic organs prolapse with transvaginal mesh kits represents nowadays a widespread surgical method, which partially replaced classic operations due to high success rate and low count of recurrences. Just like any other surgical method, the placement of transvaginal mesh is linked with occurrence of complications. In this article we attempt to review the more and less known facts about trans-vaginal meshes, their efficacy, count of recurrence and the spectrum of complications and we try to compare this technique with traditional surgical methods used to treat pelvic organs prolapse (without graft materials). Review. Department of Obstetrics and Gynecology, Regional hospital Mladá Boleslav a.s., Mladá Boleslav. Overview of the results of recent studies published in the Czech and English language in recent years. Pelvic organ prolapse repair with vaginal mesh has generally lower count of relapse especially in patients with wide genital hiatal area and with major levator ani avulsion. The spectrum of complications differs from classical techniques because of the presence of synthetic nonabsorbable material. Some of the specific complications we did not encounter during classical operations include vaginal mesh erosion, infection of mesh associated with chronic pelvic pain, dyspareunia, protrusion of the mesh into the closest organs or the rejection and progressive extrusion of the mesh. Primary enthusiasm has now been replaced with worries of major complications. Future tasks should therefore be aimed at minimizing the rate of complications associated with transvaginal meshes. Except using well-known and safe materials and providing specialized training of physicians for each mesh implantation technique, other precautions outlined in this article should help, such as a closer specification of indication for the application of transvaginal mesh.

We sought to determine if there was a potential link between synthetic polypropylene mesh implantation for transvaginal pelvic organ prolapse and stress urinary incontinence, and carcinogenesis using statewide administrative data. Women who underwent transvaginal surgery for pelvic organ prolapse or stress urinary incontinence with mesh between January 2008 and December 2009 in New York State were identified using ICD-9-CM procedure codes and CPT-4 codes. Patients in the mesh cohort were individually matched to 2 control cohorts based on comorbidities and procedure date. Carcinogenesis was determined before and after matching at 1, 2 and 3 years, and during the entire followup time. A total of 2,229 patients who underwent mesh based pelvic organ prolapse surgery and 10,401 who underwent sling surgery for stress urinary incontinence between January 2008 and December 2009 were included in the study. Mean followup was 6 years (range 5 to 7). Exact matching between the mesh and control cohorts resulted in 1,870 pairs for pelvic organ prolapse mesh and cholecystectomy (1:2), 1,278 pairs for pelvic organ prolapse mesh and hysterectomy (1:1), 7,986 pairs for sling and cholecystectomy (1:1) and 3,810 pairs for sling and hysterectomy (1:1). Transvaginal mesh implantation was not associated with an increased risk of a cancer diagnosis (pelvic/local cancers or any cancer) at 1 year and during the entire followup of up to 7 years. Transvaginal surgery with implantation of mesh was not associated with the development of malignancy at a mean followup of 6 years.

We report a case in which an intramural uterine Ieiomyoma was transvaginally expelled after uterine arterial embolization (UAE). A 29-year-old unmarried female presented with vaginal bleeding, and at pre-treatment MRI an intramural leiomyoma was diagnosed. UAE was performed and after 13 days the tumor was transvaginally expelled. Follow-up MRI performed seven days later depicted a large myometrial defect in the anterior uterine wall; subsequent follow-up MRI showed that the defect became gradually smaller, and the size and configuration of the uterus progressively normalized.

Complications of synthetic midurethral sling surgery include bladder outlet obstruction, mesh extrusion, and vaginal pain. A treatment of these complications is transvaginal mesh removal. The objectives of this video are to present cases of complications after sling placement and describe techniques to help with successful sling removal. Three patients are presented in this video. One experienced urinary hesitancy and was found to have bladder outlet obstruction on urodynamic study. The second patient presented to the clinic with diminished force of stream and significant dyspareunia. The last patient presented with mesh extrusion. After discussion of management options, all three patients wished to pursue transvaginal sling excision. All patients had successful removal of a portion of their synthetic midurethral sling. This video presents techniques to aide with dissection, mesh excision and prevention of further mesh complications. These include using an individualized surgical technique based on patient presentation and surgeon expertise, planning surgical incisions based on where mesh can be identified or palpated, using a cystoscope sheath or urethral dilator to identify any bladder outlet obstruction, and using a knife blade to identify mesh from surrounding tissue. Sling excision can be successfully performed with careful surgical technique and dissection.

Transvaginal ultrasound-guided follicle aspiration is one method of obtaining recipient oocytes for equine somatic cell nuclear transfer (SCNT). This study was conducted: (1) to evaluate the possibility of oocyte aspiration from pre-ovulatory follicles using a short disposable needle system (14-G) by comparing the oocyte recovery rate with that of a long double lumen needle (12-G); (2) to investigate the developmental competence of recovered oocytes after SCNT and embryo transfer. The recovery rates with the short disposable needle vs. the long needle were not significantly different (47.5% and 35.0%, respectively). Twenty-six SCNT embryos were transferred to 13 mares, and one mare delivered a live offspring at Day 342. There was a perfect identity match between the cloned foal and the cell donor after analysis of microsatellite DNA, and the mitochondrial DNA of the cloned foal was identical with that of the oocyte donor. These results demonstrated that the short disposable needle system can be used to recover oocytes to use as cytoplasts for SCNT, in the production of cloned foals and for other applications in equine embryology.

The aim of this prospective study was to evaluate transvaginalhysterosonography (TVHS) in post-menopausal bleeding (PMB) as an alternativeto endometrial biopsy. The study was conducted at the Zarka MilitaryHospital, Amman, Jordan, over a one year period from 1996 to 1997. The studycomprised 98 women presenting with post-menopausal bleeding who had beenlisted for diagnostic dilatation and curettage. Transvaginal sonography (TVS)and transvaginal hysterosonography were performed one week before operation.The mean age of the women was 75 years, and all of them had their menopausefor at least six months. Sixty-one women (62%) demonstrated endometrialthickness of more than 5mm by transvaginal sonography. All the women hadtransvaginal hysterosonography, except seven on whom hysterosonography couldnot be performed for technical reasons and who had to be excluded from thestudy, leaving a total 54 women. TVS confirmed the presence of endoluminalmass in 30 of 54 women (60%). Twenty-two of the 30 endoluminal mass caseswere pedunculated while eight were sessile. Sixteen of the pedunculated caseswere endometrial polyps while the remaining six were fibroid polyps. Five ofthe sessile cases were fibroid, two were endometrial hyperplasia, and thelast one endometrial carcinoma. The other 44 out of the 98 patients alsounderwent transvaginal hysterosonography. No pathology could be detected inthese patients, but they were noted to have atrophic endometrium afterdilatation and curettage. The combination of transvaginal sonography andtransvaginal hysterosonography is both sensitive and specific with regard todetecting and excluding endoluminal masses as the cause of post-menopausalbleeding. Diagnostic dilatation and curettage fails to detect a largepercentage of some lesions, so TVS in combination with TVHS should beconsidered as the initial examination in the evaluation of all women withpost-menopausal bleeding.

Laparoscopic sacrocolpopexy versus transvaginal mesh for recurrent pelvic organ prolapse.

Science.gov (United States)

Iglesia, Cheryl B; Hale, Douglass S; Lucente, Vincent R

2013-03-01

Both expert surgeons agree with the following: (1) Surgical mesh, whether placed laparoscopically or transvaginally, is indicated for pelvic floor reconstruction in cases involving recurrent advanced pelvic organ prolapse. (2) Procedural expertise and experience gained from performing a high volume of cases is fundamentally necessary. Knowledge of outcomes and complications from an individual surgeon's audit of cases is also needed when discussing the risks and benefits of procedures and alternatives. Yet controversy still exists on how best to teach new surgical techniques and optimal ways to efficiently track outcomes, including subjective and objective cure of prolapse as well as perioperative complications. A mesh registry will be useful in providing data needed for surgeons. Cost factors are also a consideration since laparoscopic and especially robotic surgical mesh procedures are generally more costly than transvaginal mesh kits when operative time, extra instrumentation and length of stay are included. Long-term outcomes, particularly for transvaginal mesh procedures, are lacking. In conclusion, all surgery poses risks; however, patients should be made aware of the pros and cons of various routes of surgery as well as the potential risks and benefits of using mesh. Surgeons should provide patients with honest information about their own experience implanting mesh and also their experience dealing with mesh-related complications.

Natural orifice transluminal endoscopic surgery (NOTES) is a novel technique that aims at reducing or abolishing skin incisions and potentially also postoperative pain. The purpose of this study was to analyse operative and long-term results of a series of hybrid transvaginal cholecystectomy. Between July 2007 and May 2009, transvaginal NOTES cholecystectomy for symptomatic cholelithiasis was performed by a hybrid technique in 18 women (mean age 54 years), including four women with a body mass index >30 kg/m(2). Dissection was conducted in the first four cases by a round-tip unipolar electrode (UE) introduced through the operative channel of the endoscope coming from the vagina and in the last 14 cases by a ultrasonic scalpel (US) introduced through a 5-mm abdominal port. The short-term outcomes and the long-term results of the two methods were compared. The transvaginal approach entailed no intraoperative complication and no conversion. The overall mean duration of procedures was 75 min (range 40-190). In the first four cases (UE), the operating time was 148 min (range 140-190), whilst in the last 14 (US), it was considerably shorter, 53 min (range 40-60, p < 0.01). We experienced one biliary leak in the UE group, whilst morbidity with US was nil (p < 0.005). The biliary leak healed in 7 days with nasobiliary drainage. No other complications were encountered in either group. The mean follow-up was 12 months (range 1-22), and none of the patients has complained of dyspareunia or other colpotomy-related complications so far. Until specifically designed endoscopic tools are available for NOTES, the hybrid technique with US dissection conducted through a 5-mm port should be preferred in transvaginal cholecystectomy in order to shorten the duration of surgery and make this approach effective, safe and reproducible. After a mean follow-up of 1 year, none of our patients has complained of any problem related to transvaginal approach.

To review the merit of the U.S. Food and Drug Administration-issued warnings on the use of transvaginal mesh in women with pelvic organ prolapse because of escalating complications. On institutional review board approval, we reviewed the data from 2 tertiary institutions managing complications of transvaginal mesh. The data recorded included mesh type, details of surgical removal, and patient-reported clinical outcomes. From 2006 to March 2011, 58 women were evaluated. Their mean age was 54.6 years (range 32-80), with a mean follow-up of 13 months (range 6-67). The mean interval to mesh excision surgery from the original prolapse surgery was 21 months (range 2-60). Of the 58 women, 35 (60%) had undergone concurrent midurethral sling surgery with the transvaginal mesh surgery. Also, 21 of the 58 patients (36%) had undergone initial mesh removal attempts before their referral to either tertiary institution. Most women presented with multiple complaints, with mesh extrusion the most frequently reported (n=43 [74%]). Of the 58 women, 17 (29%) required re-excision of residual mesh, 13 once and 4 twice. Five women developed recurrent symptomatic pelvic organ prolapse (7%). The residual rate of dyspareunia and pelvic pain was 14% and 22%, respectively. Fourteen women (24%) were treated successfully, with complete resolution of all presenting symptoms. As outlined in the Food and Drug Administration notifications, patients should be forewarned that some transvaginal mesh complications are life altering and might not always be surgically correctable.

To correlate results of Transvaginal sonography with those of hysteroscopy and biopsy in abnormal uterine bleeding to estimate the accuracy and analytical values of non-invasive transvaginal sonography in abnormal uterine bleeding. Methodology: This cross-sectional Study was carried out at BMCH, Quetta, Balochistan, Pakistan from March 2013 to February 2014 and included 200 patients of abnormal uterine bleeding. Exclusion criteria were pregnancy, virginity, local bleeding of perineal or vaginal origin. Hysteroscopy and biopsy and Transvaginal Ultrasound (TVS) were performed in all. Result: The most common type of bleeding was found to be menorrhagia in 39% while the least common type was postmenopausal bleeding in 9%. Mean endometrial thickness was 11.64 mm and it was noted that at less than 14mm thickness no serious pathology was found. Sensitivity of TVS for endometrial hyperplasia was found to be 66.66% while specificity was 100%. Positive analytical value was 100% while negative value was 100%. Overall sensitivity calculated for TVS was 94.44%, specificity 98.55%, PPV was 81.93% and NPV 98.55%. Conclusion: Sensitivity and specificity of TVS were lower than hysteroscopy and biopsy but the difference was not significant. TVS can be used as first line investigation while hysteroscopy and biopsy may be left for cases of high risk or in those cases where some positive findings could be found on TVS. (author)

2015-12-01

Abdominal wall hernias are increasingly treated by laparoscopic placement of an intraperitoneal onlay mesh (IPOM). We present an alternative technique for women: the laparoscopic-assisted transvaginal IPOM. Before surgery, all patients underwent a gynecological examination. The patients agreed to IPOM repair via a transvaginal approach, and written informed consent for surgery was obtained. Pneumoperitoneum was established with a Veress needle at the umbilicus. This access was subsequently dilated to 5 mm (VersaStep), and a 5-mm laparoscope was inserted. Under laparoscopic view, the transvaginal trocars (12-mm VersaStep and 5-mm flexible accesses) were safely inserted after lifting the uterus with a uterus manipulator. After preparation of the falciform ligament, the ligamentum teres and the preperitoneal fat, a lightweight composite mesh was introduced through the transvaginal access and fixed with absorbable tacks using the double-crown technique. From September 2011 to December 2012, we performed six laparoscopic-assisted transvaginal IPOM procedures (one epigastric, three umbilical, two combined epigastric and umbilical hernias; all were primary hernias). In the initial phase, only patients with small or medium primary abdominal wall hernia were selected (max. 3 cm diameter). Median hospital stay was 3 days (range 2-6 days). One minor complication occurred perioperatively (second-degree skin burn to the labia majora). At 1-year follow-up, we identified one recurrence in a high-risk patient with a body mass index higher than 35 kg/m(2). No infection and no mortality were observed. Although no final conclusion can be made regarding the presumed non-inferiority of this technique in terms of recurrence and mesh infection compared with traditional laparoscopic IPOM, laparoscopic-assisted transvaginal IPOM is a feasible alternative to treat abdominal wall hernias.

Heterotopic pregnancy after in vitro fertilization and embryo transfer: the role of routine transvaginal ultrasonography

Spontaneous heterotopic pregnancy (HP) is a rare condition, however, the rising incidence after in-vitro fertilization and embryo transfer (IVF-ET) may present serious problems as the diagnosis of this potentially fatal condition is often missed. The purposes of this study were to investigate the frequency of HP after IVF-ET, to analyze the clinical presentation and the outcome of coincidental intrauterine pregnancy, and to evaluate the value of routine transvaginal ultrasonography in early diagnosis and treatment of HP. There were 11 cases of HP among 484 pregnancies after IVF-ET (The incidence was 2.3%) in recent 2 years. We evaluated the clinical findings and the findings of transvaginal sonography in those 11 patients. The combined extrauterine pregnancies were tubal (n = 9), cornual (n = 1), and both the tubal and cornual (n = 1). Vaginal bleeding was absent in 4 cases and one of them was asymptomatic. HP may be suspected if there was an elevated serum hCG in the absence of intrauterine multiple gestations. In all cases, the condition was diagnosed by transvaginal sonography performed prior to surgical intervention. The coincidental intrauterine pregnancies were ended in successful full-term delivery in 7 cases, while one pregnancy was ongoing at that time. The incidence of HP was evidently higher in IVF-ET than in spontaneous pregnancies. Transvaginal sonography was useful in accurate diagnosis in clinically suspected cases and even in asymptomatic cases. Routine transvaginal sonography played an important role in early diagnosis and prompt management of HP

AIM: To determine if transvaginal ultrasound, including power Doppler examination, can distinguish between women with and without pelvic congestion. MATERIALS AND METHODS: Thirty-six women with pelvic congestion were prospectively examined using transvaginal ultrasonography and standard uterine and ovarian measurements made. Additionally, planimetric measurements of each ovary were taken using an image analysis program to determine the cross-sectional area of ovarian stroma and follicles, if any. Power Doppler images of adnexal vessels were obtained and planimetric estimates of surface area calculated. A congestion score was assigned to each patient, based on vein number, diameter and morphology on grey-scale scanning. Identical measurements were obtained from 19 asymptomatic women and results compared. RESULTS: There was no significant difference between women with pelvic congestion and controls with respect to power Doppler or grey-scale images of adnexal vessels, or congestion score. However, women with pelvic congestion had significantly larger and multicystic ovaries when compared to controls. CONCLUSIONS: Transvaginal ultrasound measurements of adnexal vasculature, including power Doppler measurements, cannot reliably distinguish women with pelvic congestion from controls. However, ultrasound may remain useful for diagnosis of pelvic congestion, predominantly because it is able to visualize multi-cystic ovaries in these patients. Halligan, S.

Objectives. To evaluate clinical outcomes following transvaginal catheter placement using transabdominal ultrasound guidance for management of pelvic fluid collections. Methods. A retrospective review was performed for all patients who underwent transvaginal catheter drainage of pelvic fluid collections utilizing transabdominal ultrasound guidance between July 2008 and July 2013. 24 consecutive patients were identified and 24 catheters were placed. Results. The mean age of patients was 48.1 years (range = 27-76 y). 88% of collections were postoperative (n = 21), 8% were from pelvic inflammatory disease (n = 2), and 4% were idiopathic (n = 1). Of the 24 patients, 83% of patients (n = 20) had previously undergone a hysterectomy and 1 patient (4%) was pregnant at the time of drainage. The mean volume of initial drainage was 108 mL (range = 5 to 570). Catheters were left in place for an average of 4.3 days (range = 1-17 d). Microbial sampling was performed in all patients with 71% (n = 17) returning a positive culture. All collections were successfully managed percutaneously. There were no technical complications. Conclusions. Transvaginal catheter drainage of pelvic fluid collections using transabdominal ultrasound guidance is a safe and clinically effective procedure. Appropriate percutaneous management can avoid the need for surgery.

The aim of the study was to compare rates of success, mesh exposure, and surgical re-intervention after trocar-guided Gynemesh PS™ and trocarless Polyform™ transvaginal mesh procedures. We conducted a retrospective cohort study of all transvaginal mesh procedures performed at our centers between January 2008 and May 2012. Multiple logistic regression models were used to explore the binary outcomes of objective and subjective success rates, as well as mesh exposure and re-intervention rates, between the two procedures after adjustment for patient's age, parity, body mass index, smoking status, previous hysterectomy, previous prolapse surgery, and follow-up time. We included 103 transvaginal mesh procedures (47 trocar-guided Gynemesh PS™ and 56 trocarless Polyform™). In both groups, Pelvic Organ Prolapse Quantification (POP-Q) scores were significantly improved after the procedure. Median follow-up was 340 days and interquartile range (IQR) 152-644. Objective success rates were 55.3 % (26/47) in the trocar group and 60.7 % (34/56) in the trocarless group (p = 0.9), whereas subjective success was 83.0 % (39/47) and 94.6 % (53/56), respectively (p = 0.1). The adjusted odds of developing mesh exposure were significantly less after trocarless transvaginal mesh procedures compared to trocar-guided ones [odds ratio (OR) 0.16, 95 % confidence interval (CI) 0.03-0.97]. Surgical re-interventions, aimed mostly at treating recurrent prolapse, mesh exposure, and latent stress urinary incontinence, were also significantly less frequent after trocarless procedures [5 patients (8.9 %) requiring re-intervention versus 15 (31.9 %), respectively, adjusted OR 0.15, 95 % CI 0.04-0.60]. Trocar-guided Gynemesh PS™ and trocarless Polyform™ transvaginal mesh systems result in similar objective and subjective success rates. The newer Polyform™ mesh results in significantly fewer mesh exposures and surgical re-interventions.

To aspirate breast abscess through a wide bore (14-gauge) intravenous (I/V) cannula and determine its efficacy in terms of the number of recurrences and number of aspirations. Case series. Dow University of Health Sciences and Civil Hospital and Bantva Hospital, Karachi, Pakistan, from January 2009 to December 2011. Patients with breast abscesses confirmed on ultrasound without skin ulceration were selected. The soft area of breast abscess with positive fluctuation was marked and fixed with index finger and thumb. A 14-gauge cannula was inserted. Pus was aspirated through a 50 cc syringe, repeated till no aspirate could be obtained. All patients were followed weekly for 4 weeks, clinically for size of lump, local tenderness and temperature, while complete resolution was confirmed on ultrasound, as resolution of the lesion. A total of 55 patients were included in this study. Mean age was 29 ± 5.58 years while ranging from 20 - 40 years. Complete resolution of abscess was seen in 31 (56.4%) cases by single aspiration. Second aspiration was required in 24 (43.6%) patients and third aspiration in single setting was required in one case only. Recurrence after the second aspiration occurred in 08 (14.5%). Incision drainage was required in 7 (12.7%) patients. Percutaneous aspiration of breast abscess through a wide bore (14-gauge) I/V cannula is a simple alternative to incision and drainage.

Laparoscopy using a single port improves morbidity while keeping the same level of requirement. This technique has been evaluated in gynecology for salpingectomy, ovarian surgery, and hysterectomy. Here, the authors illustrate a new use of a single port using the transvaginal approach. Case report (Canadian Task Force classification III). Tertiary referral center in Strasbourg, France. Woman age 59 years. Single-port platform used in the transvaginal approach for resection of sacrocolpopexy mesh. The local institutional review board approved the video. A 59-year-old woman suffering from insulin-dependent diabetes and a tobacco user had 2 laparoscopic sacrocolpopexies for recurrent rectocele, the first in 2007 and the second in 2012. The sequences were marked by mesh erosion and granuloma in the vagina, requiring its surgical excision in 2016. The patient was then symptomatic, with an increasingly foul-smelling vaginal discharge with recurrent mesh erosion. Magnetic resonance imaging showed an abscess formation along the length of the mesh to the promontory. The patient then underwent surgery, realized under probabilistic antibiotic therapy, consisting of complete excision of the sacrocolpopexy mesh by the transvaginal approach. After putting the single-port trocar (GelPoint; Applied Medical, Rancho Santa Margarita, CA) into the vagina and obtaining distension with the insufflator (AirSeal; Conmed, Utica, NY), classic laparoscopic instruments were introduced by the single-port trocar. The mesh was entirely resected in the retroperitoneal space. Mesh was again used because the exposed space is almost always surrounded by loose granulation tissue that facilitates dissection and also prevents injury to adjacent structures such as bladder, rectum, and peritoneum. Moreover, the opening of adjacent structures will manifest gas leaks and, consequently, loss of the pneumovagina. At the end of procedure, the vagina is not closed to permit optimal drainage with a multitubular

To assess adverse events following surgical repair of pelvic organ prolapse (POP) with or without the use of transvaginal mesh. The present retrospective study was conducted among women who underwent surgical POP repair at Soroka University Medical Center, Beer Sheva, Israel, between January 1, 2013, and December 31, 2015. Patients underwent anterior and posterior colporrhaphy either with transvaginal mesh (Elevate Prolapse Repair System; American Medical Systems, Minnetonka, MN, USA) or without transvaginal mesh (native tissue repair). Perioperative adverse events were assessed using the Clavien-Dindo classification; multivariate regression models were constructed to predict minor and major adverse events. There were 111 women included; 35 were treated with transvaginal mesh, and 76 underwent native tissue repair. Women undergoing native tissue repair had a lower mean grade of cystocele (P=0.023) and a higher rate of urinary stress incontinence (P=0.017) than patients treated with transvaginal mesh. The duration of surgery (P=0.002), duration of hospitalization (Ptransvaginal mesh was not associated with increased odds of major or minor adverse events (P>0.05 for all models examined). Perioperative and postoperative adverse events were comparable regardless of the operative approach. © 2018 International Federation of Gynecology and Obstetrics.

The transobturator suburethral sling is a common surgical treatment for stress urinary incontinence (SUI). In patients with incontinence after trocar-guided transvaginal mesh repair (Prolift), data on outcome remain limited. In the present study, we hypothesized that transobturator tape in such cases is assumed to be as effective as surgery alone. This was a prospective analysis of outcomes of transobturator slings in women who had undergone transvaginal mesh repair and in those who underwent sling surgery alone (controls). Objective cure was defined as the absence of urinary leakage during the stress test at filling cystometry and a negative cough test during pelvic examination. The success rates were evaluated 3-6 months postoperatively. One hundred women were recruited for the study. Compared to the control group, women after transvaginal mesh repair had a significantly lower objective success rate (62 vs 86%, p = 0.005) and poorer bladder neck mobility (0.5 ± 0.8 vs 1.1 ± 0.5 cm, p = 0.001). The transobturator sling has lower objective success rate in women after transvaginal mesh that may be due to decreased bladder neck mobility. Patients with post-mesh repair SUI who opt for sling surgery should be informed of these less satisfactory outcomes during preoperative counseling.

This guideline reviews the evidence related to the risks and benefits of using transvaginal mesh in pelvic organ prolapse repairs in order to update recommendations initially made in 2011. Gynaecologists, residents, urologists, urogynaecologists, and other health care providers who assess, counsel, and care for women with pelvic organ prolapse. Adult women with symptomatic pelvic organ prolapse considering surgery and those who have previously undergone transvaginal mesh procedures for the treatment of pelvic organ prolapse. The discussion relates to transvaginal mesh procedures compared with other surgical options for pelvic organ prolapse (mainly about vaginal native tissue repairs and minimally about other alternatives such as biological and absorbable vaginal mesh and abdominally placed surgical mesh). The outcomes of interest are objective and subjective success rates and intraoperative and postoperative complications, such as adjacent organ injury (urinary, gastrointestinal), infection, hematoma/bleeding, vaginal mesh exposure, persistent pain, dyspareunia, de novo stress urinary incontinence, and reoperation. PubMed, Medline, the Cochrane Database, and EMBASE were searched using the key words pelvic organ prolapse/surgery*, prolapse/surgery*, surgical mesh, surgical mesh*/adverse effects, transvaginal mesh, and pelvic organ prolapse. were restricted to English or French language and human research. Articles obtained through this search strategy were included until the end of June 2016. Pertinent new studies were added up to September 2016. Grey literature was not searched. Clinical practice guidelines and guidelines of specialty societies were reviewed. Systematic reviews were included when available. Randomized controlled trials and observational studies were included when evidence for the outcome of interest or in the target population was not available from systematic reviews.

Prompted by patients' changing perceptions of transvaginal mesh, this study examines how mesh has been reported in the news following the 2011 US Food and Drug Administration (FDA) updated notification about the use of mesh in the treatment of pelvic organ prolapse. Two national newspaper databases were queried for articles discussing transvaginal mesh published within 3 years of the FDA announcement. Content analysis included headline subjects, mesh-related complications, quoted sources, and the FDA recommendations. To determine whether more widely read sources publish higher quality reporting, a subgroup analysis was conducted based on newspaper circulation. Ninety-five articles met inclusion criteria. Mesh-related litigation was the most common headline subject (36 articles, 38%), and 54% of all articles referenced legal action. Fifty-seven articles (60%) cited at least one mesh-related complication. Only 18 articles (19%) quoted surgeons who use transvaginal mesh. For the FDA update, 40% of articles that first reported the announcement accurately specified that it applies to mesh for prolapse, not incontinence. This ambiguity persisted: half of all articles cited the warning, but only 23% distinguished between prolapse and incontinence. Higher newspaper circulation did not significantly improve the quality of reporting about the content or context of the FDA's recommendations. Despite frequent media coverage of transvaginal mesh and its complications since 2011, very few news sources that cited the FDA warning distinguished between prolapse and incontinence. Given prevalent reporting of mesh-related litigation, the findings raise concern about how patients perceive the safety and efficacy of transvaginal mesh, regardless of indication. Neurourol.

Science.gov (United States)

Zoorob, Dani; Karram, Mickey; Stecher, Anna; Maxwell, Rose; Whiteside, James

To identify litigation predictors among women with complications of transvaginal mesh. Chart review and patient survey were conducted among women who had undergone a complication-related explant of a transvaginal prolapse or incontinence sling mesh. Trained study personnel administered a 57-question survey addressing subjective complaints related to bowel, bladder, sexual dysfunction, and development of pain or recurrent prolapse. These data were analyzed with respect to the subject's reported pursuit of litigation related to the mesh complication. Categorical and continuous variables were analyzed using the χ test and the t test as indicated. Ninety-five (68%) of 139 women completed the surveys with 60% of the patients pursuing litigation at the time of the survey. Individual risk factors for pursuing litigation included development of vaginal pain after mesh placement (P = 0.01); dyspareunia after mesh placement (P = 0.01); persistence of dyspareunia, suprapubic pain, and groin pain after mesh excision (P = 0.04, P = 0.02, and P = 0.001, respectively); unsuccessful attempts at conservative management of pelvic pain using pelvic floor rehabilitation (P = 0.002). There is an association between a higher likelihood of pursuing litigation and new-onset or persistent pain symptoms attributable to transvaginal mesh.

2010-01-01

Background: Ventral incisional hernias still remain a common surgical problem. We tested the feasibility of transvaginal placement of a large synthetic mesh to repair a porcine hernia. Methods: Seven pigs were used in this survival model. Each animal had creation of a 5-cm hernia defect and underwent a transvaginal repair of the defect with synthetic mesh. A single colpotomy was made using a 12-cm trocar for an overtube. The mesh was cut to size and placed through the trocar. A single-channel gastroscope with an endoscopic atraumatic grasper was used for grasping sutures. Further fascial sutures were placed every 5cm. Results: Mesh repair was feasible in all 7 animals. Mean operative time was 133 minutes. Technical difficulties were encountered. No gross contamination was seen at the time of necropsy. However, 5 animals had positive mesh cultures; 7 had positive cultures in the rectouterine space in enrichment broth or on direct culture. Conclusion: Transvaginal placement of synthetic mesh to repair a large porcine hernia using NOTES is challenging but feasible. Future studies need to be conducted to develop better techniques and determine the significance of mesh contamination. PMID:20932375

To determine if laparoscopic sacral colpopexy (LSC) offers better apical support with a lower exposure rate than transvaginal mesh surgery with Elevate™. This was a retrospective cohort study comparing patients with apical prolapse (POP-Q point C ≥ -1) who underwent Elevate™ mesh repair (n = 146) with patients who underwent laparoscopic sacral colpopexy (n = 267). The sacral colpopexy group had a mean age of 59 years and a BMI of 25.7. Patients in the Elevate™ group were older, with a mean age of 63 and a BMI of 26.3. Most of the patients of both groups presented with pelvic organ prolapse stage III (LSC 73.8% and Elevate™ 87.0%) and their mean POP-Q point C were not significantly different (LSC 1.4 vs Elevate™ 1.2 cm). Operative time was longer in the LSC group (113 vs 91 min, p < 0.001), but estimated blood loss was lower (75 cm 3 vs 137 cm 3 , p < 0.001). No difference in mesh exposure rate could be found between the two groups at one year (Elevate™ 0.7% vs LSC 2.6%, OR 0.26, 95% CI 0.03 to 2.10, p = 0.21). One-year objective cure rate, defined as no descent beyond the hymen, was 97.0% in the LSC group and 96.6% in the Elevate™ group (p = .81). The overall recurrence (objective, subjective recurrence or reoperation) was also not different between the groups (LSC 4.5% vs Elevate 4.8%, p = 0.89). Transvaginal Elevate™ mesh delivers comparable apical support with a low exposure rate similar to that of laparoscopic sacral colpopexy.

The use of standardized mesh kits for repair of pelvic-organ prolapse has spread rapidly in recent years, but it is unclear whether this approach results in better outcomes than traditional colporrhaphy. In this multicenter, parallel-group, randomized, controlled trial, we compared the use of a trocar-guided, transvaginal polypropylene-mesh repair kit with traditional colporrhaphy in women with prolapse of the anterior vaginal wall (cystocele). The primary outcome was a composite of the objective anatomical designation of stage 0 (no prolapse) or 1 (position of the anterior vaginal wall more than 1 cm above the hymen), according to the Pelvic Organ Prolapse Quantification system, and the subjective absence of symptoms of vaginal bulging 12 months after the surgery. Of 389 women who were randomly assigned to a study treatment, 200 underwent prolapse repair with the transvaginal mesh kit and 189 underwent traditional colporrhaphy. At 1 year, the primary outcome was significantly more common in the women treated with transvaginal mesh repair (60.8%) than in those who underwent colporrhaphy (34.5%) (absolute difference, 26.3 percentage points; 95% confidence interval, 15.6 to 37.0). The surgery lasted longer and the rates of intraoperative hemorrhage were higher in the mesh-repair group than in the colporrhaphy group (Pmesh-repair group and 0.5% in the colporrhaphy group (P=0.07), and the respective rates of new stress urinary incontinence after surgery were 12.3% and 6.3% (P=0.05). Surgical reintervention to correct mesh exposure during follow-up occurred in 3.2% of 186 patients in the mesh-repair group. As compared with anterior colporrhaphy, use of a standardized, trocar-guided mesh kit for cystocele repair resulted in higher short-term rates of successful treatment but also in higher rates of surgical complications and postoperative adverse events.

Obstetrical and Gynecological Devices; Reclassification of Surgical Mesh for Transvaginal Pelvic Organ Prolapse Repair; Final order.

Science.gov (United States)

2016-01-05

The Food and Drug Administration (FDA or the Agency) is issuing a final order to reclassify surgical mesh for transvaginal pelvic organ prolapse (POP) repair from class II to class III. FDA is reclassifying these devices based on the determination that general controls and special controls together are not sufficient to provide reasonable assurance of safety and effectiveness for this device, and these devices present a potential unreasonable risk of illness or injury. The Agency is reclassifying surgical mesh for transvaginal POP repair on its own initiative based on new information.

Full Text Available We report the prenatal diagnosis of Cantrell syndrome in the first trimester. During a routine transabdominal ultrasonographic examination, a midline supraumbilical abdominal wall defect including herniated liver and ectopia cordis with a large omphalocele containing the intestines and cystic hygroma was incidentally identified at the 12th week of gestation. A transvaginal sonography examination revealed a severe lumbosacral scoliosis in addition to the inability to visualize the abdominal aorta which was indicative of a severe intracardiac defect. The parents opted for pregnancy to be terminated. In this case report, we discuss the complementary role of transvaginal sonography and Doppler imaging in the diagnosis of Cantrell syndrome in early pregnancy.

To determine whether the transvaginal sonographic appearance of the thickened endometrium can help to predict the underlying endometrial pathologic process. The sonogram reports of fall 41 pre- and 21 postmenopausal women who underwent transvaginal sonogram were retrospectively analyzed. The women undergoing estrogen replacement therapy, tamoxifen therapy or having abnormal cervical cytology were excluded from this study. The analysis of sonographic and histologic results was performed in all patients. Three distinct sonographic patterns were encountered. Type I consisted of heterogeneous endometrial thickening with internal hypoechoic areas (normal [n=4], polyp [n=1] and cancer [n=4] in premenopausal women and cancer [n=4] in postmenopausal women). Type II consisted of echogenic endometrial thickening with or without tiny cysts (normal[n=5], and hyperplasia [n=7] in premenopausal women and normal [n=4], polyp [n=2], and hyperplasia [n=1] in postmenopausal women). Type III consisted of localized well defined endoluminal lesion (normal [n=1], polyp [n=14], hyperplasia [n=1], cancer [n=1], and submucosal mass [n=3] in premenopausal women and normal [n=4], polyp [n=2],submucosal mass [n=3], and hematoma [n=1] in postmenopausal women). The measurement of the endometrial thickness combined with analysis of sonographic echo patterns may be helpful in prediction and differentiation of endometrial disease in pre- and postmenopausal women. Also it can contribute to avoiding unnecessary D and C.

Full Text Available Objective: to report two benign liver lesions treatment under minilaparoscopic-assisted transvaginal approach. Patients and methods: females, 44 and 45 years old, respectively, were treated. Patient 1 showed a 1,2 cm Ø tumor located in the left liver lobe. In preoperative studies was not possible to discern the etiology, for what was decided surgical treatment. The patient 2 showed a symptomatic liver simple cyst, 8 cm Ø, located in the subsegment VI. She refused percutaneous treatment, it was recommended surgical treatment under general anesthesia. The surgical intervention offered was either the laparoscopic or the transvaginal approach, but this latter was accepted. Pneumoperitoneum with 15 mmHg was used. Two small trocars were inserted into the abdomen. The first one (5 mm Ø at the umbilical region, the second one (3 mm Ø near the lesion. One trocar 11 mm Ø, was placed in the posterior cul-de-sac. In patient 1 a large dissector was introduced adjacent to the trocar. In the patient 2, one second trocar 5 mm Ø was introduced in vagina for operative instruments. Both specimens were extracted through the vagina, protected in extractor bags. Variables studied: operating room time; analgesia required and post-operative complications. Results: the operating room times were 51 and 73 min, respectively. Only the patient with hepatic liver cyst required post-operative analgesia for pain at the right upper quadrant. Both patients were discharged before 24 hours. No postsurgical complications were found in the 6 months follow up. Conclusions: using transvaginal approach assisted with minilaparoscopy was possible to carry out surgical treatment in benign and non complex liver lesions located in outlying subsegments. It is a safe method with better aesthetic result than laparoscopic surgery. Nevertheless, will be necessary future studies that demonstrate the advantages of this approach in the hepatic lesions.Objetivo: reportar dos casos de lesiones

Fine-needle aspiration biopsy (FNAB) may yield different results depending on its operator. We compared the proportions of unsatisfactory aspirates obtained by pathologists vs. surgeons. In a retrospective review, all FNAB reports and slides performed between March 2002 and February 2003 were grouped by organ/site and according to whether they were done by pathologist or a surgeon. The proportions of unsatisfactory aspirates for pathologists and surgeons were compared. Of 692 FNAB's, 390 were performed by pathologists at the FNAC clinic and the remainder by surgeons. Overall, 15.5% of aspirates obtained were unsatisfactory (n=107). Of aspirates obtained by surgeons, 29.5% were unsatisfactory, compared to 4.6% of those obtained by pathologists (P<0.001). Pathologists had significantly lower proportions of unsatisfactory aspirates in all sites. A 33% reduction in the number of lymph node excisional biopsies has been reported subsequent to establishment of the FNAC clinic. The advantages of a pathologist performing FNAB are that a rapid evaluation can be rendered regarding specimen adequacy and the need for repeating the procedure. In addition, pathologists can direct the distribution of aspirated material for other tests such as culture study, flow cytometry and electron microscopy, as indicated by preliminary evaluation of the smears. These factors significantly lower the proportions of unsatisfactory specimens and improve the diagnstic accuracy of FNAB technique. (author)

Complications from transvaginal mesh placed for prolapse often require operative management. The aim of this study is to describe the outcomes of vaginal mesh removal. A retrospective review of all patients having surgery by the urogynecology group in the department of obstetrics and gynecology at our institution for a complication of transvaginal mesh placed for prolapse was performed. Demographics, presenting symptoms, surgical procedures, and postoperative symptoms were abstracted. Comparative statistics were performed using the χ or Fisher's exact test with significance at Pmesh and 84 had follow-up data. The most common presenting signs and symptoms were: mesh exposure, 62% (n=56); pain, 64% (n=58); and dyspareunia, 48% (n=43). During operative management, mesh erosion was encountered unexpectedly in a second area of the vagina in 5% (n=4), in the bladder in 1% (n=1), and in the bowel in 2% (n=2). After vaginal mesh removal, 51% (n=43) had resolution of all presenting symptoms. Mesh exposure was treated successfully in 95% of patients, whereas pain was only successfully treated in 51% of patients. Removal of vaginal mesh is helpful in relieving symptoms of presentation. Patients can be reassured that exposed mesh can almost always be successfully managed surgically, but pain and dyspareunia are only resolved completely in half of patients. III.

2004-01-01

Objective: To find the accuracy of sonographic information provided by transvaginal sonography (TVS) in pelvic pathology as compared to transabdominal sonography (TAS). Materials and Methods: Hundred patients were included in the study from a total of 212 referred for pelvic sonography. Two radiologists independently performed transabdominal and transvaginal sonography of these patients. An independent observer compared the findings. TVS was graded as superior, equal or inferior to TAS depending on the score assigned by them. Results: TVS was considered superior in 63%, equal in 27% and inferior in 10% of the cases as compared to transabdominal sonography. It was graded inferior to TAS in cases with large pelvic masses and superior in majority of cases of ovarian follicle monitoring, polycystic ovaries, endometrial carcinoma and suspected ectopic pregnancy. Cases in which both techniques were considered equal included patients with no abnormal finding, some pelvic masses and advanced pelvic inflammatory disease. Conclusion: Transvagival sonography is superior to transabdominal sonography in most cases of pelvic pathology. However, TAS should still be the initial sonographic technique for routine evaluation of the female pelvis followed by TVS if indicated. In cases of ovarian follicle monitoring, suspected polycystic ovaries, endometrial pathology and suspected ectopic pregnancy, TVS may be used as the initial sonographic technique and can even replace TAS.

Olecranon bursitis might be a minor problem in the outpatient clinic but relatively be common to occur. However, there are few well-designed studies comparing approaches to treatment. (1) Which treatment (compression bandaging with nonsteroidal antiinflammatory drugs [NSAIDs], aspiration, or aspiration with steroid injections) is associated with the highest likelihood of resolution of nonseptic olecranon bursitis? (2) Which treatment is associated with earliest resolution of symptoms? (3) What factors are associated with treatment failure by 4 weeks? We enrolled 133 patients from two centers; after applying prespecified exclusions (septic bursitis or concomitant inflammatory arthritis, intraarticular elbow pathology, recent aspiration or steroid injection done elsewhere, and refusal to participate), 90 patients were randomly allocated to receive compression bandaging with NSAIDs (C), aspiration (A), or aspiration with steroid injection (AS) groups (30 patients in each). The groups were similar at baseline in terms of age and gender. Seven patients (four from Group A and three from Group AS) were lost to followup. All patients were followed up weekly for 4 weeks, and the same treatment procedure was repeated if the bursitis recurred with any substantial fluid collection. At 4 weeks, the state of resolution and pain visual analog scale (VAS) were evaluated. Failed resolution was defined as presence of persistent olecranon bursal fluid collection at Week 4 after the initiation of the treatment; on the contrary, if bursal fluid collection was clinically reduced or completely disappeared by the end of Week 4, the treatment was considered successful. We compared the proportion of resolution by Week 4 and the median times to resolution among the treatment groups. In addition, we evaluated whether the resolution affected pain VAS and what factors were associated with the resolution. There were no differences in the proportion of patients whose bursitis resolved by Week 4

Full Text Available Objective To describe a novel technique of repairing the VVF using the transperitoneal-transvaginal approach. Materials and Methods From June 2011 to October 2013, four patients with symptoms of urine leakage in the vagina underwent robotic repair of VVF with the transperitoneal-transvaginal approach. Cystoscopy revealed the fistula opening on the bladder. A ureteral stent was placed through the fistulous tract. After trocar placement, the omental flap was prepared and mobilized robotically. The vagina was identified and incised. The fistulous tract was excised. Cystorrhaphy was performed in two layers in an interrupted fashion. The vaginal opening was closed with running stitches. The omentum was interposed and anchored between the bladder and vagina. Finally, the ureteral catheters were removed in case they have been placed, and an 18 Fr urethral catheter was removed on the 14th postoperative day. Results The mean age was 46 years (range: 41 to 52 years. The mean fistula diameter was 1.5 cm (range 0.3 to 2 cm. The mean operative time was 117.5 min (range: 100 to 150 min. The estimated blood loss was 100 mL (range: 50 to 150 mL. The mean hospital stay was 1.75 days (range: 1 to 3 days. The mean Foley catheter duration was 15.75 days (range: 10 to 25 days. There was no evidence of recurrence in any of the cases. Conclusions The robot-assisted laparoscopic transperitoneal transvaginal approach for VVF is a feasible procedure when the fistula tract is identified by first intentionally opening the vagina, thereby minimizing the bladder incision and with low morbidity.

To know what is the meaning of non-diagnostic results of fine needle aspiration biopsy (FNAB) and whether repeated aspiration is needed or not in those situations. We reviewed 1845 patients who underwent FNAB from 1997 to 2001. Non-diagnostic results of the first FNAB were divided into four groups: insufficient number of cells, inflammatory cells, necrotic debris and atypical cells. We analyzed final diagnosis of 531 patients who had non-diagnostic results from the first FNAB. Among them, 207 lesions were re-biopsied because of clinical and radiologic suspicion of malignancy. The diagnostic yield of repeated FNAB was analyzed and compared with the results of the first FNAB. Among 255 cases with 'inflammatory cells only' results, 120 cases were confirmed benignancy on follow-up. Twenty nine of 50 stypical cells (58%) were malignant of follow-up. One hundred one of 207 repeated FNAB resulted in the non-diagnostic reports, and 106 of 207 repeated FNAB were diagnosed as specific diagnosis. Among thirty lesions showing atypical cells on the repeated FNAB, 22 (73%) were identified as malignant neoplasms. When the specimen of FNAB shows atypical cells, the possibility of malignancy is very high. When the results of FNAB is non-diagnostic in the cases with clinical and radiological suspicion of malignancy, repeated FNAB procedures should be seriously considered and will be helpful for accurate specific diagnosis

The benefits are presented of cytological examination of bioptical material from the pancreas using computerized tomography (CT) or ultrasound. The case is presented of one patient who had repeatedly undergone endoscopy with no results. Only cytological examination of material sampled using fine needle aspiration under CT control helped to immediately diagnose the process. The cytological finding correlated with the histological examination of material later taken during surgery. The problems are discussed of the differential diagnosis of tumors of the pancreas.

Hurtado, Eric A; Appell, Rodney A

2009-01-01

This case series' purpose is to review a referral center's experience with complications from mesh kits. A chart review of 12 patients who presented with complications associated with transvaginal mesh kit procedures was performed. All patients underwent complete surgical removal of the mesh to treat mesh exposure, pain, or vaginal bleeding/discharge followed by an anterior or posterior repair. The mean follow-up time after surgery was 3.4 months. Eight of 12 patients had mesh that had formed a fibrotic band. Six of 12 patients had complete resolution of pain. Of the nine patients with mesh exposure, all required significant resection of the vaginal wall. No further mesh exposure occurred. The use of transvaginal mesh kits may cause previously undescribed complications such as pelvic/vaginal pain or large extrusions requiring complete removal. Removal of all mesh except the arms may cure or significantly improve these problems.

Transvaginal mesh repair has been discredited due to high complications rates in the past years. Therefore, we evaluated the quality of life (QoL) and complication rates after transvaginal mesh (TVM) repair for pelvic organ prolapse (POP). A total of 148 women who underwent TVM repair for symptomatic POP were retrospectively enrolled. Complication rates and functional outcomes were retrospectively assessed and validated, standardised questionnaires were used prospectively for evaluation of QoL. Univariate analysis by the chi(2)-test as well as a multivariate Cox regression analysis was conducted to predict mesh exposure using various variables as predictors. Intraoperative complications with bowel or bladder injury appeared in 3.4%. Mesh exposure occurred in 2.7% whereas surgical revision was necessary only in 1.4%. No predictor for mesh exposure could be identified. Postoperative complications according to Clavien-Dindo classification ≥ III occurred in only 2.8%. An improvement of POP-symptoms was reported by 84.6% according the "patients' global impression of improvement" (PGI-I) and 88.2% women would repeat the surgery. The results of the "prolapse-quality of life"-questionnaire were comparable to asymptomatic women. Only 33% reported vaginal pain with a mean vaginal pain score of 0.6 according the international index of pain. Of sexually active women, 29% reported sexual impairments and mean score of sexual impairment was 1.52. Low complication rates and a quality of life comparable to asymptomatic women following TVM repair could be achieved in our cohort. However, a high number of sexual impairments was identified although the impact of impairment was marginal. Copyright © 2016 IJS Publishing Group Ltd. Published by Elsevier Ltd. All rights reserved.

To show a new technique of laparoscopic intracorporeal anastomosis for transrectal bowel resection with transvaginal specimen extraction, a technique particularly suited for treatment of bowel endometriosis. Step-by-step explanation of the technique using videos and pictures (educative video). Endometriosis may affect the bowel in 3% to 37% of all endometriosis cases. Bowel endometriosis affects young women, without any co-morbidities and in particular without any vascular disorders. In addition, affected patients often express a desire for childbearing. Radical excision is sometimes required because of the impossibility of conservative treatment such as shaving, mucosal skinning, or discoid resection. Bowel endometriosis should not be considered a cancer, and consequently maximal resection is not the objective. Rather, the goal would be to achieve functional benefit. As a result, resection must be as economic and cosmetic as possible. The laparoscopic approach has proved its superiority over the open technique, although mini-laparotomy is generally performed to prepare for the anastomosis. Total laparoscopic approach in patients with partial bowel stenosis, using the vagina for specimen extraction. This technique of intracorporeal anastomosis with transvaginal specimen extraction enables a smaller resection and avoidance of abdominal incision enlargement that may cause hernia, infection, or pain. When stenosis is partial, this technique seems particularly suited for treatment of bowel endometriosis requiring resection. If stenosis is complete, the anvil can be inserted above the lesion transvaginally. Copyright © 2013 AAGL. Published by Elsevier Inc. All rights reserved.

Update on Instrumentations for Cholecystectomies Performed via Transvaginal Route: State of the Art and Future Prospectives

Full Text Available Natural Orifice Transluminal Endoscopic Surgery (NOTES is an innovative approach in which a flexible endoscope enters the abdominal cavity via the transesophageal, transgastric, transcolonic, transvaginal or transvescical route, combining the technique of minimally invasive surgery with flexible endoscopy. Several groups have described different modifications by using flexible endoscopes with different levels of laparoscopic assistance. Transvaginal cholecystectomy (TVC consists in accessing the abdominal cavity through a posterior colpotomy and using the vaginal incision as a visual or operative port. An increasing interest has arisen around the TVC; nevertheless, the most common and highlighted concern is about the lack of specific instruments dedicated to the vaginal access route. TVC should be distinguished between “pure”, in which the entire operation is performed through the transvaginal route, and “hybrid”, in which the colpotomy represents only a support to introduce instruments and the operation is performed mainly by the classic transabdominal-introduced instruments. Although this new technique seems very appealing for patients, on the other hand it is very challenging for the surgeon because of the difficulties related to the mode of access, the limited technology currently available and the risk of complications related to the organ utilized for access. In this brief review all the most recent advancements in the field of TVC's techniques and instrumentations are listed and discussed.

Dysphagia and bolus aspiration are two of the most frequent and invalidating symptoms of various neurological diseases. Swallowing disorders often lead to tracheobronchial aspiration with consequent pneumonia episodes. Aspiration pneumonia per se constitutes the most frequent cause of death in these patients, with mortality rate ranging from 20% to 62%. Oropharyngoesophageal scintigraphy (OPES) permits functional quantitative assessment of the different stages of swallowing, together with the detection and quantitative measurement of bolus aspiration. In this work, we analyzed the role of OPES in patients with different neurological conditions to evaluate swallowing and to detect and quantify bolus aspiration. We enrolled 43 neurological patients (25 women and 18 men, mean age 67.3±12.4 yr) complaining of dysphagia with suspected inhalation. All patients underwent OPES with (99m)Tc-nanocolloid using a liquid bolus first, followed by a semi-solid bolus. We evaluated the following parameters: Oral, Pharyngeal and Esophageal Transit Time, Oro-Pharyngeal Retention Index, Esophageal Emptying Rate, and Aspiration Rate (% AR). OPES detected some airway aspiration in 26/43 patients. 19 patients had tracheal aspiration (with a mean 18.1% AR) and the remaining 7 patients had bilateral broncho-pulmonary aspiration (mean 44.9% AR). OPES is a feasible, repeatable and noninvasive method that allows quantitative assessment of bolus aspiration into the tracheobronchial tract, thus representing a useful and accurate tool to guide the most appropriate treatment and to monitor response to therapy in neurological patients with dysphagia.

Background and purpose: We would like to assess the prevalence of aspiration before and following chemoradiation for head and neck cancer. Patients and methods: We reviewed retrospectively the Modified Barium Swallow (MBS) in 63 patients who underwent concurrent chemotherapy and radiation for head and neck cancer. MBS was performed prior to treatment to determine the need for immediate gastrostomy tube placement. MBS was repeated following treatment to assess the safety of oral feeding prior to removal of tube feeding. All patients were cancer free at the time of the swallowing study. No patient had surgery. Dysphagia severity was graded on a scale of 1-7. Tube feedings were continued if patients were diagnosed to have severe aspiration (grade 6-7) or continued weight loss. Patients with abnormal swallow (grade 3-7) received swallowing therapy following MBS. Results: Before treatment, there were 18 grade 1, 18 grade 2, 9 grade 3, 8 grade 4, 3 grade 5, 3 grade 6, and 4 grade 7. Following chemoradiation, at a median follow-up of 2 months (1-10 months), one patient had grade 1, eight patients had grade 2, nine patients had grade 3, eight patients had grade 4, 13 patients had grade 5, seven patients had grade 6, and 11 patients had grade 7. Six patients died from aspiration pneumonia (one before, three during, and two post-treatment), and did not have the second MBS. Overall, 37/63 (59%) patients developed aspiration, six of them (9%) fatal. If we excluded the 10 patients who had severe aspiration at diagnosis and the six patients who died from pneumonia, the prevalence of severe aspiration was 33% (21/63). Conclusions: Aspiration remained a significant morbidity following chemoradiation for head and neck cancer. Its prevalence is underreported in the literature because of its often silent nature. Diagnostic studies such as MBS should be part of future head and neck cancer prospective studies to assess the prevalence of aspiration, and for rehabilitation

Natural orifice transluminal endoscopic surgery (NOTES) is the consequence of further development of minimally invasive surgery to reduce abdominal incisions and surgical trauma. The potential benefits are expected to be less postoperative pain, faster convalescence, and reduced risk for incisional hernias and wound infections compared to conventional methods. Recent clinical studies have demonstrated the feasibility and safety of transvaginal NOTES, and transvaginal access is currently the most frequent clinically applied route for NOTES procedures. However, despite increasing clinical application, no firm clinical evidence is available for objective assessment of the potential benefits and risks of transvaginal NOTES compared to the current surgical standard. The TRANSVERSAL trial is designed as a randomized controlled trial to compare transvaginal hybrid NOTES and laparoscopic-assisted sigmoid resection. Female patients referred to elective sigmoid resection due to complicated or reoccurring diverticulitis of the sigmoid colon are considered eligible. The primary endpoint will be pain intensity during mobilization 24 hours postoperatively as measured by the blinded patient and blinded assessor on a visual analogue scale (VAS). Secondary outcomes include daily pain intensity and analgesic use, patient mobility, intraoperative complications, morbidity, length of stay, quality of life, and sexual function. Follow-up visits are scheduled 3, 12, and 36 months after surgery. A total sample size of 58 patients was determined for the analysis of the primary endpoint. The confirmatory analysis will be performed based on the intention-to-treat (ITT) principle. The TRANSVERSAL trial is the first study to compare transvaginal hybrid NOTES and conventionally assisted laparoscopic surgery for colonic resection in a randomized controlled setting. The results of the TRANSVERSAL trial will allow objective assessment of the potential benefits and risks of NOTES compared to the

Commercial prolapse mesh kits are increasingly used in the management of pelvic organ prolapse. We present our experience with the transvaginal/perineal management of synthetic mesh related complications from prolapse kits. In addition, we used the new ICS/IUGA (International Continence Society/International Urogynecological Association) prostheses/grafts complication classification system to report on our contemporary series. A retrospective chart review of all patients who underwent surgical removal of transvaginal mesh for mesh related complications after prolapse kit use from November 2006 to April 2010 at 1 institution was performed. We report our contemporary series of mesh complications using the new ICS/IUGA prostheses/grafts complication classification system. Postoperative pain, degree of improvement and presence of continued symptoms were reported by patients at last followup. A total of 23 patients underwent transvaginal removal of mesh during the study period. Mean patient age was 61 years. Median period of latency to mesh related complication was 10 months (range 1 to 27). Indications for mesh removal included vaginal/pelvic pain (39%), dyspareunia (39%), vaginal mesh extrusion/exposure (26%), urinary incontinence (35%), recurrent pelvic organ prolapse (22%), bladder mesh perforation with recurrent urinary tract infection (22%), rectal mesh perforation (4%), ureteral perforation injury (4%), retained foreign body (surgical sponge) in the bladder (4%) and vesicovaginal fistula (9%), with most patients citing more than 1 reason. Although technically difficult in some cases, purely transvaginal mesh excision appears to be safe with resolution of almost all presenting symptoms. Although slightly cumbersome, the new ICS/IUGA prostheses/graft complication classification system can be used to report and more accurately characterize mesh complications.

Synthetic mesh kits recently adopted in pelvic reconstructive surgeries have achieved great surgical efficacy, but the effects of transvaginal synthetic mesh procedures on women's sexual function are still controversial. This study was conducted to demonstrate sexual function in women before and after surgery with transvaginal mesh (TVM) repair for pelvic organ prolapse (POP). A total of 93 sexually active women scheduled for correcting POP with synthetic mesh kits were recruited. In addition to urogynecological history, pelvic examination by the Pelvic Organ Prolapse Quantification system, and urodynamic testing, consenting participants were asked to complete the Pelvic Organ Prolapse/Urinary Incontinence Sexual Questionnaire (PISQ-12) to evaluate sexual function before and after surgery. At the 3-month urodynamic studies, among the 25 patients with coexistent urodynamic stress incontinence (USI) who had undergone a concomitant transobturator suburethral tape procedure (TOT), 1 (4 %) had persistent USI; 8 of 68 (11.8 %) patients with a negative pessary test developed postoperative USI. Six-month prolapse recurrence rates following TVM alone and TVM with concomitant TOT were 9 and 12 %, respectively. The total PISQ-12 score after surgery showed worse results in the TVM alone group but not in the TVM with concomitant TOT group. The individual scores of PISQ-12 after surgery demonstrated prolapse-related items improved in both TVM groups; sexual function worsened in dyspareunia and behavior domains. Our data revealed that transvaginal synthetic mesh procedures for the treatment of POP generated favorable clinical outcomes, but situations might worsen in dyspareunia and behavior domains, thereby invoking a negative emotional reaction during intercourse after surgery.

Full Text Available Introduction: Pelvic varicose veins, one of the main causes of chronic pelvic pain and dyspareunia, are an important source of reflux for lower limb varicose veins, especially in recurrent cases. Color Doppler ultrasound of the lower limbs and transvaginal ultrasound are the noninvasive diagnostic methods most commonly used to assess pelvic venous insufficiency, whereas phlebography is still considered as the gold standard. Objectives: To determine the prevalence of lower limb varicose veins originating from the pelvis in a group of female patients and to determine the agreement between results obtained via color Doppler ultrasound of the lower limbs, transvaginal ultrasound, and phlebography. Methods: The sample comprised female patients referred to a vascular laboratory for lower limb screening. Patients diagnosed with deep venous thrombosis were excluded. Data analysis included kappa coefficient of agreement, McNemar's test, sensitivity and specificity values. Results: Of a total of 1,020 patients, 124 (12.2% had findings compatible with reflux of pelvic origin. Among these patients, 51 (41.2% were recurrent cases. A total of 249 were submitted to transvaginal ultrasound. There was significant agreement between lower limb ultrasonographic findings and transvaginal findings. Phlebography was performed in 54 patients. The comparison between transvaginal ultrasound and phlebography was associated with a 96.2% sensitivity and 100% specificity. Conclusions: The authors draw attention to the relatively high prevalence of lower limb varicose veins originating from the pelvis, suggesting an important but underdiagnosed cause of recurrent varicose veins.Introdução: AS VARIZES Pélvicas, uma das principais causas de dor pélvica crônica e dispareunia, são uma importante fonte de refluxo para as varizes dos membros inferiores, especialmente em casos recorrentes.

To investigate long-term outcomes after transvaginal mesh repair among patients with pelvic organ prolapse in different age groups. A retrospective cohort study was conducted among women who underwent transvaginal mesh repair with polypropylene mesh for pelvic organ prolapse of stage II or higher between January 2007 and November 2011 at a center in Shanghai, China. Patients were invited to attend a follow-up appointment between July 2014 and May 2015. Surgical outcomes were compared among three age groups (≤59, 60-74, and ≥75 years), and quality-of-life questionnaires were evaluated. Multivariate logistic regression was used to identify risk factors associated with recurrent prolapse and mesh exposure. Among 158 patients, 143 (90.5%) were objectively cured and 149 (94.3%) were subjectively cured at follow-up. Surgical outcomes were similar across all age groups. Significant improvements were observed on the Pelvic Floor Distress Inventory across all applicable subscales in all age groups (Pmesh exposure (odds ratio 11.89, 95% confidence interval 1.08-131.48; P=0.043). Transvaginal mesh repair was found to be a safe and effective technique for treating pelvic organ prolapse among women of all ages. An active postoperative sex life increased the odds of mesh exposure. Copyright © 2016 International Federation of Gynecology and Obstetrics. Published by Elsevier Ireland Ltd. All rights reserved.

New ultrasound techniques may complement current diagnostic tools, and combined techniques may help to overcome the limitations of individual techniques for the diagnosis of anorectal dysfunction. A high degree of agreement has been demonstrated between echodefecography (dynamic 3-dimensional anorectal ultrasonography) and conventional defecography. Our aim was to evaluate the ability of a combined approach consisting of dynamic 3-dimensional transvaginal and transrectal ultrasonography by using a 3-dimensional biplane endoprobe to assess posterior pelvic floor dysfunctions related to obstructed defecation syndrome in comparison with echodefecography. This was a prospective, observational cohort study conducted at a tertiary-care hospital. Consecutive female patients with symptoms of obstructed defecation were eligible. Each patient underwent assessment of posterior pelvic floor dysfunctions with a combination of dynamic 3-dimensional transvaginal and transrectal ultrasonography by using a biplane transducer and with echodefecography. Kappa (κ) was calculated as an index of agreement between the techniques. Diagnostic accuracy (sensitivity, specificity, and positive and negative predictive values) of the combined technique in detection of posterior dysfunctions was assessed with echodefecography as the standard for comparison. A total of 33 women were evaluated. Substantial agreement was observed regarding normal relaxation and anismus. In detecting the absence or presence of rectocele, the 2 methods agreed in all cases. Near-perfect agreement was found for rectocele grade I, grade II, and grade III. Perfect agreement was found for entero/sigmoidocele, with near-perfect agreement for rectal intussusception. Using echodefecography as the standard for comparison, we found high diagnostic accuracy of transvaginal and transrectal ultrasonography in the detection of posterior dysfunctions. This combined technique should be compared with other dynamic techniques and

Disordered swallowing, or dysphagia, is almost always present to some degree in people with Parkinson's disease (PD), either causing aspiration or greatly increasing the risk for aspiration during swallowing. This likely contributes to aspiration pneumonia, a leading cause of death in this patient population. Effective airway protection is dependent upon multiple behaviors, including cough and swallowing. Single voluntary cough function is disordered in people with PD and dysphagia. However, the appropriate response to aspirate material is more than one cough, or sequential cough. The goal of this study was to examine voluntary sequential coughing in people with PD, with and without dysphagia. Forty adults diagnosed with idiopathic PD produced two trials of sequential voluntary cough. The cough airflows were obtained using pneumotachograph and facemask and subsequently digitized and recorded. All participants received a modified barium swallow study as part of their clinical care, and the worst penetration-aspiration score observed was used to determine whether the patient had dysphagia. There were significant differences in the compression phase duration, peak expiratory flow rates, and amount of air expired of the sequential cough produced by participants with and without dysphagia. The presence of dysphagia in people with PD is associated with disordered cough function. Sequential cough, which is important in removing aspirate material from large- and smaller-diameter airways, is also impaired in people with PD and dysphagia compared with those without dysphagia. There may be common neuroanatomical substrates for cough and swallowing impairment in PD leading to the co-occurrence of these dysfunctions.

Transobturator tapes are preferable over transvaginal tapes for the management of female stress urinary incontinence: Against

Directory of Open Access Journals (Sweden)

2009-01-01

Full Text Available Midurethral placement of tension-free vaginal tapes with a transvaginal route for stress urinary incontinence achieves higher and better long-term success rates than the transobturator route. Bladder perforations are reported more in transvaginal tape (TVT but incidences of vaginal erosions, extrusion, and groin pain are exceedingly more in TOT groups. There is no clear evidence that transobturator tape (TOT is associated with less post-operative voiding problems than TVT. Major complications such as bowel injuries and significant vascular injuries with TVT are rare. TVT has been found to be superior to TOT and preferable in technically demanding conditions such as prior anti-incontinence operation failures, obese women, and very elevated and scarred lateral cul-de sac. TVT is always preferred in severe grades of stress urinary incontinence and with patients of intrinsic sphincter deficiency (ISD with little or no urethral mobility.

The present study aims to determine how transvaginal ultrasonography and histopathological examination findings are correlated in a cohort of premenopausal and postmenopausal Turkish women with abnormal uterine bleeding. This is a retrospective review of 350 Turkish women who underwent transvaginal ultrasonography and suction curettage as a result of abnormal uterine bleeding. Sonographic appearance of the endometrium was normal in 244 patients (69.7%), while homogeneous thickening was detected in 47 patients (13.4%) and cystic thickening in 21 patients (6.0%). A sonographic diagnosis of endometrial polyp was made in 38 patients (10.9%). Histopathological analysis of endometrial samplings revealed proliferative endometrium (36%), secretory endometrium (24.6%), decidualization (10.9%), endometrial polyp (8.3%), endometritis (6.8%), endometrial hyperplasia (4.6%), irregular shedding (3.7%), atrophic endometrium (3.1%), endometrial cancer (1.1%) and placental retention (0.9%). The sonographic and histopathological findings correlated significantly (χ(2) = 122 768, P = 0.001; r = 0.215, P = 0.001). Approximately 51% of the women with homogeneous endometrial thickening had proliferative endometrium. Only 44.7% of the women with ultrasonographically visualized endometrial polyps had histopathologically diagnosed endometrial polyps. Nearly 57% of the women with cystic endometrial thickening had proliferative endometrium. If there is no facility for hysteroscopy or hysteroscopy-guided endometrial biopsy for women with abnormal uterine bleeding, transvaginal ultrasonography findings can be efficiently used to make a preliminary diagnosis and, thus, notify the pathologists. © 2016 Japan Society of Obstetrics and Gynecology.

2016-07-01

The aim of this study was to report long-term subjective and objective outcomes after the transvaginal mesh (TVM) procedure in long-term. Possible late-onset complications were of particular interest. This was a retrospective analysis of TVM performed using Prolift™ transvaginal mesh measuring subjective outcome using validated questionnaires. Objective outcome was assessed using the Pelvic Organ Prolapse Quantification (POP-Q) system using two definitions: POP-Q stage ≤ 1, and vaginal wall prolapse at or above the hymen or vaginal apex not descending below the upper third of the vagina. Complications were reported with the Prosthesis/Graft Complication Classification Code designed by the International Continence Society/International Urogynecological Association (ICS/IUGA). Of 195 patients, 161 (82.6 %) participated this study after a median of 7 years. The scores in questionnaires evaluating urinary (UI) or anal incontinence and constipation or pelvic floor symptoms were low, indicating favorable surgical outcomes. Altogether, 80.1 % of patients were satisfied with the procedure. Anatomical cure was 56.4 % and 69.3 % depending on the definition used. Reoperation due to POP in any compartment was performed in 16.2 % of patients. Mesh exposure rate was 23 %, most of these being asymptomatic and of late onset. Outcome of the TVM procedure was satisfactory. Anatomical cure was inferior to subjective cure. Mesh exposure rate was high; most exposures observed in the long-term were of late onset and were asymptomatic.

DiBardino, David M; Wunderink, Richard G

2015-02-01

The purpose was to describe aspiration pneumonia in the context of other lung infections and aspiration syndromes and to distinguish between the main scenarios commonly implied when the terms aspiration or aspiration pneumonia are used. Finally, we aim to summarize current evidence surrounding the diagnosis, microbiology, treatment, risks, and prevention of aspiration pneumonia. Medline was searched from inception to November 2013. All descriptive or experimental studies that added to the understanding of aspiration pneumonia were reviewed. All studies that provided insight into the clinical aspiration syndromes, historical context, diagnosis, microbiology, risk factors, prevention, and treatment were summarized within the text. Despite the original teaching, aspiration pneumonia is difficult to distinguish from other pneumonia syndromes. The microbiology of pneumonia after a macroaspiration has changed over the last 60 years from an anaerobic infection to one of aerobic and nosocomial bacteria. Successful antibiotic therapy has been achieved with several antibiotics. Various risks for aspiration have been described leading to several proposed preventative measures. Aspiration pneumonia is a disease with a distinct pathophysiology. In the modern era, aspiration pneumonia is rarely solely an anaerobic infection. Antibiotic treatment is largely dependent on the clinical scenario. Several measures may help prevent aspiration pneumonia. Copyright © 2014 Elsevier Inc. All rights reserved.

2013-10-01

Necrotising fasciitis is a severe form of soft tissue infection. Herein, we present an unreported complication of the transvaginal repair of a pelvic organ prolapse (POP) with trocar-guided polypropylene mesh and a concomitant hysterectomy. A 61-year-old Caucasian female who had been using an intrauterine device (IUD) for 30 years presented with a stage 3 pelvic organ prolapse. A genital ultrasound examination confirmed the presence of an IUD, but found no endometrial abnormalities. The surgical management was limited to a transvaginal hysterectomy and simultaneous anterior vaginal wall repair augmented with trocar-guided mesh. A morphological examination of the removed uterus confirmed the presence of the intrauterine device and additionally found endometrial cancer (T1N0M0), which was not revealed during the preoperative ultrasound. Within 6 days of the surgery, she developed anaerobic bilateral necrotising fasciitis on both thighs. Non-clostridial streptococci were identified in the wound. After 18 days of intensive care, the patient died of fatal coagulopathy.

2011-01-01

Purpose: Our purpose was to report the outcome of endovascular treatment with manual aspiration thrombectomy as the first-line thromboablative method for phlegmasia cerulea dolens. Methods: Between October 2006 and May 2010, seven consecutive patients (5 women, 2 men; age range, 31–80 years) with the diagnosis of phlegmasia cerulea dolens secondary to acute iliofemoral deep venous thrombosis had endovascular treatment with manual aspiration thrombectomy. Catheter-directed thrombolysis and stent placement were used as adjunctive procedures. Phlegmasia was left-sided in five and right-sided in two patients. Results: All patients had associated great saphenous vein thrombosis in addition to iliofemoral deep vein thrombosis (DVT). Aspiration thrombectomy completely removed the thrombus from the popliteal vein to the inferior vena cava (IVC) in all cases. Three patients with May-Thurner syndrome had stent placement in the left common iliac vein. Two patients had early recurrences. Repeated aspiration thrombectomy was unsuccessful in one patient. There were no complications related to the procedure. One patient who had been successfully treated died of sepsis and another patient who had unsuccessful repeated interventions had below-the-knee amputation. Overall, the clinical success and survival rates of patients in this study were 86%. On follow-up, three patients with successful treatment were asymptomatic with no deep venous insufficiency. One of these patients died during the 4-month follow-up period. Two patients had mild ankle swelling with deep venous insufficiency. Conclusions: Manual aspiration thrombectomy with adjunctive use of catheter-directed thrombolysis and stent placement is an effective endovascular treatment method with high clinical success and survival rates for phlegmasia cerulean dolens.

Traditionally, aspiration with high negative pressure is recommended to obtain a specimen in transbronchial needle aspiration (TBNA). Undeniably, however, the assistant experiences difficulty in the generation of the negative pressure and precise control of the syringe while performing the procedure. To evaluate the effectiveness of the autoaspiration method created by our plunger lock in comparison with the conventional manual aspiration in the diagnosis of intrathoracic lymphadenopathy by TBNA. A prospective study was conducted on all patients referred for diagnostic TBNA of enlarged intrathoracic lymph nodes. Both automatic and manual aspiration techniques were performed after the needle had been completely inserted into the nodes. The diagnostic yield and the numbers of diagnostic cells or benign lymphoid cells obtained by each technique were compared in the same node. A total of 31 intrathoracic lymph nodes in 24 patients were prospectively studied. Twenty-four nodes (77.4%) were malignancies whereas 7 nodes (22.6%) were benign disease. Adequate lymph node samples were obtained in 30 targets (96.8%), and TBNA revealed definite diagnosis for 25 nodes (80.6%). Both aspiration techniques showed exactly the same diagnostic yield. However, the autoaspiration technique provided significantly more adequate samples than manual aspiration techniques did (P=0.003). The autoaspiration method using our plunger lock was superior to the manual method in obtaining the numbers of adequate samples in TBNA procedures.

A proposal to reduce the risk of transmission of human papilloma virus via transvaginal ultrasound.

Science.gov (United States)

Combs, C Andrew; Fishman, Alan

2016-07-01

Three steps must be followed to prevent the transmission of infection via a contaminated transvaginal ultrasound probe: cleaning the probe after every use, high-level disinfection, and covering the probe with a single-use barrier during the examination. There may be critical flaws in at least 2 of these steps as they are currently practiced. First, 2 widely used disinfectants, glutaraldehyde and orthophthalaldehyde, have recently been found to be ineffective at neutralizing human papilloma virus type 16 and type 18. Second, commercial ultrasound probe covers have an unacceptable rate of leakage (8-81%) compared to condoms (0.9-2%). We recommend the use of a sonicated hydrogen peroxide disinfectant system rather than aldehyde-type disinfectants. We recommend that the probe be covered with a condom rather than a commercial probe cover during transvaginal ultrasound examination. Combined with probe cleaning, these 2 steps are estimated to result in an 800 million- to 250 billion-fold reduction in human papilloma virus viral load, which should translate to greatly enhanced patient safety.

Tracheobronchial Foreign Body Aspiration: Dental Prosthesis

Directory of Open Access Journals (Sweden)

Ataman Köse

2014-01-01

Full Text Available It is important to extract foreign bodies for avoiding life-threatening complications. They can lead to death if they are not treated. Different signs and symptoms could occur according to the complete or partial airway obstruction. Foreign body aspiration is a rare incident in adults. The organic foreign materials such as foods are found to be aspirated more commonly and are usually settled in the right bronchial system. However, dental prosthesis and teeth aspirations are rare in literature. In our study, a 52-year-old male patient who had aspirated the front part of his lower dental prosthesis accidentally is presented and the foreign body is extracted by using rigid bronchoscopy. There are many causes of aspiration but dental prosthetic aspirations should be kept in mind during sleep. For this reason, dental apparatus must be taken out while asleep.

Comparative study of aspiration and non-aspiration cytology of palpable breast lumps and correlation with histopathology

Directory of Open Access Journals (Sweden)

S Koirala

2014-09-01

Full Text Available Background: Breast lump is one of the most common presentations in surgical outpatient departments with anxiety regarding a possible malignancy. Hence a quick diagnosis of a lump in the breast is essential. Fine needle aspiration cytology is an ideal initial diagnostic modality in breast lumps. There is an alternative method of performing needle aspiration, known as fine needle capillary cytology where the specimen is obtained using just a needle without aspiration.Materials and Methods: This hospital-based cross sectional analytical study was carried out in Department of Pathology in National Academy of Medical Sciences, Bir Hospital for one year. The objective of this study was to compare aspiration and non-aspiration cytology of palpable breast lumps and correlation with histopathology.Results: The five criteria scored for each technique were background blood, amount of cellular material, cellular degeneration, cellular trauma and architectural preservation. Compared to fine needle aspiration cytology, fine needle capillary cytology yields less bloody smears with minimal degenerative changes and offers more diagnostically superior specimens. Fine needle aspiration cytology, on the other hand, gives a good yield of diagnostic material.Conclusion: Fine needle aspiration cytology and fine needle capillary cytology are quick, easy, safe and cost-effective techniques. . A high sensitivity and specificity of cytological diagnosis in this study proves that it is comparable to final histology report in its diagnostic efficiency. Thus, fine needle aspiration cytology is a very important preliminary diagnostic test in palpable breast lumps and the results show a high degree of correlation with the final histopathology report.DOI: http://dx.doi.org/10.3126/jpn.v4i8.11501 Journal of Pathology of Nepal; Vol.4,No. 8 (2014 639-643

We reviewed the outcomes of the autologous fascial pubovaginal sling as a salvage procedure for recurrent stress incontinence after intervention for polypropylene mesh erosion/exposure and/or bladder outlet obstruction in patients treated with prior transvaginal synthetic mesh for stress urinary incontinence. In a review of surgical databases at 2 institutions between January 2007 and June 2013 we identified 46 patients who underwent autologous fascial pubovaginal sling following removal of transvaginal synthetic mesh in simultaneous or staged fashion. This cohort of patients was evaluated for outcomes, including subjective and objective success, change in quality of life and complications between those who underwent staged vs concomitant synthetic mesh removal with autologous fascial pubovaginal sling placement. All 46 patients had received at least 1 prior mesh sling for incontinence and 8 (17%) had received prior transvaginal polypropylene mesh for pelvic organ prolapse repair. A total of 30 patients underwent concomitant mesh incision with or without partial excision and autologous sling placement while 16 underwent staged autologous sling placement. Mean followup was 16 months. Of the patients 22% required a mean of 1.8 subsequent interventions an average of 6.5 months after autologous sling placement with no difference in median quality of life at final followup. At last followup 42 of 46 patients (91%) and 35 of 46 (76%) had achieved objective and subjective success, respectively. There was no difference in subjective success between patients treated with a staged vs a concomitant approach (69% vs 80%, p = 0.48). Autologous fascial pubovaginal sling placement after synthetic mesh removal can be performed successfully in patients with stress urinary incontinence as a single or staged procedure.

To assess aspirations for physical health over 18 months. To examine whether maintained importance of aspirations for physical health mediated and/or moderated the effect of an intensive intervention on long-term tobacco abstinence. Participants were randomly assigned to an intervention based on self-determination theory or to community care, and provided data at baseline and at 18 and 30 months post-randomization. Aspirations for physical health were better maintained over 18 months among participants in the intervention (mean change=.05), relative to community care (mean change=-.13), t=2.66, p<.01. Maintained importance of aspirations for physical health partially mediated the treatment condition effects on seven-day point prevalence tobacco abstinence (z'=1.68, p<.01) and the longest number of days not smoking (z'=2.16, p<.01), and interacted with treatment condition to facilitate the longest number of days not smoking (beta=.08, p<.05). Maintained importance of aspirations for physical health facilitated tobacco abstinence. Smokers may benefit from discussing aspirations for physical health within autonomy-supportive interventions. Patients may benefit from discussing aspirations during counseling about therapeutic lifestyle change and medication use.

Comparison of the CDC Backpack aspirator and the Prokopack aspirator for sampling indoor- and outdoor-resting mosquitoes in southern Tanzania

Directory of Open Access Journals (Sweden)

Mgando Joseph

2011-06-01

Full Text Available Abstract Background Resting mosquitoes can easily be collected using an aspirating device. The most commonly used mechanical aspirator is the CDC Backpack aspirator. Recently, a simple, and low-cost aspirator called the Prokopack has been devised and proved to have comparable performance. The following study evaluates the Prokopack aspirator compared to the CDC backpack aspirator when sampling resting mosquitoes in rural Tanzania. Methods Mosquitoes were sampled in- and outdoors of 48 typical rural African households using both aspirators. The aspirators were rotated between collectors and households in a randomized, Latin Square design. Outdoor collections were performed using artificial resting places (large barrel and car tyre, underneath the outdoor kitchen (kibanda roof and from a drop-net. Data were analysed with generalized linear models. Results The number of mosquitoes collected using the CDC Backpack and the Prokopack aspirator were not significantly different both in- and outdoors (indoors p = 0.735; large barrel p = 0.867; car tyre p = 0.418; kibanda p = 0.519. The Prokopack was superior for sampling of drop-nets due to its smaller size. The number mosquitoes collected per technician was more consistent when using the Prokopack aspirator. The Prokopack was more user-friendly: technicians preferred using the it over the CDC backpack aspirator as it weighs considerably less, retains its charge for longer and is easier to manoeuvre. Conclusions The Prokopack proved in the field to be more advantageous than the CDC Backpack aspirator. It can be self assembled using simple, low-cost and easily attainable materials. This device is a useful tool for researchers or vector-control surveillance programs operating in rural Africa, as it is far simpler and quicker than traditional means of sampling resting mosquitoes.

The aim of our study is to present our experience with uterine restoration after repeated sloughing of uterine fibroids or transvaginal expulsion following uterine artery embolization (UAE) and to determine its safety and outcome. One hundred and twenty-four women (mean age, 40.3 years; age range, 29-52 years) with symptomatic uterine fibroids were included in this retrospective study. We performed arterial embolization with poly(vinyl alcohol) particles (250-710 {mu}m). Clinical symptoms and follow-up information for each patient were obtained through medical records. At an average of 3.5 months (range, 1-8 months) after embolization, magnetic resonance imaging examinations with T1- and T2-weighted and gadolinium-enhanced T1-weighted images were obtained for all patients. The mean follow-up duration was 120 days (90-240 days). Eight (6.5%) patients experienced uterine restoration after repeated sloughing of uterine fibroids or spontaneous transvaginal expulsion. The locations of the leiomyomas were submucosal (n=5), intramural (n=2) and transmural (n=1). The maximum diameter of the fibroids ranged from 3.5 to 18.0 cm, with a mean of 8.4 cm. The time interval from embolization to the uterine restoration was 7-150 days (mean 70.5 days). The clinical symptoms before and during vaginal sloughing or expulsion were lower abdominal pain (n=4), vaginal discharges (n=3), infection of necrotic myomas (n=2) and cramping abdominal pain (n=1). Gentle abdominal compression (n=1) and hysteroscopic assistance (n=1) were required to remove the whole fibroid. No other clinical sequelae, either early or delayed, were documented. Magnetic resonance images revealed the disappearance of leiomyomas, intracavitary rupture resulting in transformation of intramural or transmural myomas into submucosal myomas and localized uterine wall defects. Although the small size of this study precludes a strict conclusion, there appear to be few serious complications directly related to vaginal

To assess the incidence of aspiration pneumonia in infants with cleft palate and to compare the incidence between complete and incomplete types of cleft palate. A review of medical records revealed 100 infants who had undergone initial surgery to repair cleft palate in our hospital during a recent three-year period. Aspiration pneumonia was defined as the coexistence of pneumonia at chest radiography with a history of frequent choking during feeding. The anatomic distribution of aspiration pneumonia was analyzed, and the incidences of aspiration pneumonia in infants with complete and incomplete cleft palate were compared. Among 100 children, aspiration pneumonia was found in 35 (35%). Those with complete and incomplete cleft palate showed similar incidences of the condition (27 of 70 [39%] vs 8 of 30 [27%], p=0.36). Pneumonia was most commonly seen in the left lower lobe (11 of 35), followed by the right upper and lower lobes. Aspiration pneumonia is frequently associated with infants with cleft palate. There is no statistical difference in the incidence of aspiration pneumonia between the complete and the incomplete cleft palate group.

Transvaginal sonography (TVS is a popular tool for IUL detection, but there are conflicting data with respect to its accuracy.Methods: Five hundred and six women were enrolled into the study. Of these, 496 underwent hysterosalpingography and subsequent TVS six different times during the course of their menstrual cycle. If a lesion was detected, it was further evaluated by sonohysterography (SHG and hysteroscopy.Results: Of 496 women, 41 were shown to have IULs by TVS and those lesions were confirmed in 39 by SHG and hysteroscopy. All 39 lesions were detectable during the ovulatory and early luteal phase (days 16–19 of the menstrual cycle. Accuracy of TVS during different phases was largely dependent on the size of the lesion. TVS falsely detected two lesions and missed fine adhesions in two patients.Conclusion: Accuracy of TVS in detection of IULs is highly dependent on the menstrual cycle phase, with the ovulatory and early luteal phase being the optimal time for this examination.Keywords: menstrual cycle phase, space occupying lesions, transvaginal sonography

To compare the impact of virtual reality simulation training and theoretical teaching on the ability of inexperienced trainees to produce adequate virtual transvaginal ultrasound images. We conducted a randomized controlled trial with parallel groups. Participants included inexperienced residents starting a training program in Paris. The intervention consisted of 40 minutes of virtual reality simulation training using a haptic transvaginal simulator versus 40 minutes of conventional teaching including a conference with slides and videos and answers to the students' questions. The outcome was a 19-point image quality score calculated from a set of 4 images (sagittal and coronal views of the uterus and left and right ovaries) produced by trainees immediately after the intervention, using the same simulator on which a new virtual patient had been uploaded. Experts assessed the outcome on stored images, presented in a random order, 2 months after the trial was completed. They were blinded to group assignment. The hypothesis was an improved outcome in the intervention group. Randomization was 1 to 1. The mean score was significantly greater in the simulation group (n = 16; mean score, 12; SEM, 0.8) than the control group (n = 18; mean score, 9; SEM, 1.0; P= .0302). The quality of virtual vaginal images produced by inexperienced trainees was greater immediately after a single virtual reality simulation training session than after a single theoretical teaching session. © 2015 by the American Institute of Ultrasound in Medicine.

Full Text Available Purpose Different techniques for cystocele repair including the conventional anterior colporrhaphy and mesh technique are known. Our goal was to evaluate the anatomical success and safety of our method of transvaginal anterior vaginal wall repair by the purse-string technique reinforced with three simple additional sutures in the repair of cystocele over a 4-year follow-up period. Methods This was a retrospective review of 69 consecutive patients (grades 2 to 4 who underwent the above operations between 2001 and 2011, including their success rates as assessed by use of the Baden-Walker halfway classification system. Results Of the patients, 62 patients (98% were completely cured of cystocele and 1 patient showed grade 2 cystocele recurrence that required no further treatment. Two patients with grade 4 cystocele were completely cured. There was no vaginal erosion related to the cystocele repair. Conclusions Transvaginal anterior colporrhaphy by a purse-string technique reinforced with simple additive sutures appears to be a simple, safe, and easily performed approach in cystocele repair. There is no need for other material for reinforcement, even in high-grade cystocele, which is an advantage of our technique.

Declotting a Thrombosed Brescia-Cimino Fistula by Manual Catheter-Directed Aspiration of the Thrombus

International Nuclear Information System (INIS)

Turmel-Rodrigues, Luc A

2005-01-01

Acute thrombosis of native fistulae for hemodialysis occurs more rarely than for prosthetic grafts. The vascular access should be reopened as soon as possible in order to resume regular dialysis and to avoid resorting to a temporary central line. Manual aspiration is one of the numerous methods described in this setting. Clinical examination is essential to rule out local infection, which is the only serious contraindication to percutaneous maneuvers. Two introducer-sheaths are placed in a criss-cross fashion in order to gain access to the venous outflow and to the anastomosis. Access to the venous outflow is performed first in order to check the proximal extent of the thrombosis. Heparin and antibiotics are injected systemically. A similar maneuver is then performed in the direction of the anastomosis. The aspiration phase is then initiated. A 7-9 Fr aspiration catheter is pushed through the 'venous' introducer. Manual aspiration is created through a 50 ml syringe while the catheter is progressively removed with back and forth movements. The catheter and the contents of the syringe are flushed through a gauze on the working table to evaluate the amount of thrombus which has been removed and the maneuver is repeated as often as necessary to remove all the thrombus. Once all the clots located downstream from the venous introducer have been removed, any unmasked underlying stenosis is NOT dilated at this stage since it provides protection against major embolism coming from the inflow. The aspiration catheter is then pushed through the 'arterial' introducer down to the anastomosis in order to aspirate the thrombus located between the tip of the introducer and the anastomosis. Dilatation of unmasked stenoses is finally performed using high-pressure balloons. The holes made by the two introducers are closed using a U-shaped suture with interposition of a short piece of plastic and the patient is sent back to the nephrologists for dialysis

Amebic liver abscess (ALA) is a common and serious problem in our country. There are only a few controlled trials on the efficacy and advantages of combination therapy with percutaneous needle aspiration and pharmacotherapy, over pharmacotherapy alone for amebic liver abscess. This study was conducted to compare the efficacy of two different treatment modalities i.e. drug treatment alone vs. drug treatment and aspiration of abscess cavity in patients with small (up to 5 cm) and large (5 cm to 10 cm) size ALA. This is one of the largest single center, prospective, randomized studies comparing the efficacy of aspiration in ALA. (i) Mean body temperature, liver tenderness, total leukocyte count (TLC), serum alanine aminotransferase (ALT) and liver span were significantly decreased in the aspiration group on days 8 and 15 as compared to non-aspiration group especially in large abscess (5 cm to 10 cm). (ii) Abscess cavity maximum diameter decreased significantly in aspiration group on days 8 and 15, and 1 month & 3 months in large abscess (5cm to 10 cm). (i) Needle aspiration along with metronidazole hastens clinical improvement especially in large (5 cm up to 10 cm) cavities in patients with ALA. (ii) Aspiration is safe and no major complications occurred. (iii) Hence, combination therapy should be the first choice especially in large ALA (5 cm to 10 cm).

Full Text Available It is important to assess patients of difficult/therapy resistant asthma carefully in order to identify whether there are any correctable factors that may contribute to their poor control. It is critical to make a diagnosis of asthma and to exclude other airway diseases. A 65-years-old lady presented with repeated acute episodes of dyspnoea and wheezing. She was on regular medication for bronchial asthma for 18 years. There was no history of foreign body aspiration or loss of consciousness. Her chest radiograph was normal. She showed poor response to corticosteroids and bronchodilators. Fibreoptic bronchoscopy (FOB showed intracordal cyst of the left vocal cord and 1cm size irregular piece of betel nut in right main bronchus, which was removed endoscopically with the help of dormia basket, following which her condition improved and asthma was controlled on inhaled bronchodilators.

Full Text Available Aspiration can cause a diverse spectrum of pulmonary disorders some of which can lead to death but can be difficult to diagnose.The medical records and autopsy findings of 57 consecutive patients in whom aspiration was the immediate cause of death at Mayo Clinic (Rochester, MN, USA over a 9-yr period, from January 1 2004 to December 31 2012 were analyzed.The median age at death was 72 years (range, 13-95 years and included 39 (68% males. The most common symptom before death was dyspnea (63% and chest radiography revealed bilateral infiltrates in the majority (81%. Most common precipitating factors for aspiration were depressed consciousness (46% and dysphagia (44%. Aspiration-related syndromes leading to death were aspiration pneumonia in 26 (46%, aspiration pneumonitis in 25 (44%, and large airway obstruction in 6 patients (11%. Aspiration was clinically unsuspected in 19 (33% patients. Antimicrobial therapy had been empirically administered to most patients (90% with aspiration pneumonia and aspiration pneumonitis.We conclude aspiration-related deaths occur most commonly in the elderly with identifiable risks and presenting bilateral pulmonary infiltrates. One-third of these aspiration-related pulmonary syndromes were clinically unsuspected at the time of death.

Spatially correlated heterogeneous aspirations to enhance network reciprocity

Tanimoto, Jun; Nakata, Makoto; Hagishima, Aya; Ikegaya, Naoki

2012-02-01

Perc & Wang demonstrated that aspiring to be the fittest under conditions of pairwise strategy updating enhances network reciprocity in structured populations playing 2×2 Prisoner's Dilemma games (Z. Wang, M. Perc, Aspiring to the fittest and promoted of cooperation in the Prisoner's Dilemma game, Physical Review E 82 (2010) 021115; M. Perc, Z. Wang, Heterogeneous aspiration promotes cooperation in the Prisoner's Dilemma game, PLOS one 5 (12) (2010) e15117). Through numerical simulations, this paper shows that network reciprocity is even greater if heterogeneous aspirations are imposed. We also suggest why heterogeneous aspiration fosters network reciprocity. It distributes strategy updating speed among agents in a manner that fortifies the initially allocated cooperators' clusters against invasion. This finding prompted us to further enhance the usual heterogeneous aspiration cases for heterogeneous network topologies. We find that a negative correlation between degree and aspiration level does extend cooperation among heterogeneously structured agents.

Feasibility of Tomotherapy-based image-guided radiotherapy to reduce aspiration risk in patients with non-laryngeal and non-pharyngeal head and neck cancer.

Directory of Open Access Journals (Sweden)

Nam P Nguyen

Full Text Available PURPOSE: The study aims to assess the feasibility of Tomotherapy-based image-guided radiotherapy (IGRT to reduce the aspiration risk in patients with non-laryngeal and non-hypopharyngeal cancer. A retrospective review of 48 patients undergoing radiation for non-laryngeal and non-hypopharyngeal head and neck cancers was conducted. All patients had a modified barium swallow (MBS prior to treatment, which was repeated one month following radiotherapy. Mean middle and inferior pharyngeal dose was recorded and correlated with the MBS results to determine aspiration risk. RESULTS: Mean pharyngeal dose was 23.2 Gy for the whole group. Two patients (4.2% developed trace aspiration following radiotherapy which resolved with swallowing therapy. At a median follow-up of 19 months (1-48 months, all patients were able to resume normal oral feeding without aspiration. CONCLUSION AND CLINICAL RELEVANCE: IGRT may reduce the aspiration risk by decreasing the mean pharyngeal dose in the presence of large cervical lymph nodes. Further prospective studies with IGRT should be performed in patients with non-laryngeal and non-hypopharyngeal head and neck cancers to verify this hypothesis.

Full Text Available Purpose: This study aimed to evaluate the clinical outcomes and complications of transvaginal minimal mesh repair without using commercially available kits for treatment of pelvic organ prolapse (POP. Materials and Methods: This retrospective cohort study involved 91 women who underwent surgical management of POP with originally designed small mesh between July 2014 and August 2015. This mesh is 56% smaller than the mesh widely used in Japan, and it has only two arms delivered into each right and left sacrospinous ligament. The main study outcome was the anatomic cure rate defined as recurrence of POP quantification (POP-Q stage II or more. We also assessed changes in the overactive bladder symptom score (OABSS and prolapse quality of life questionnaire (P-QOL and evaluated adverse events. Finally, we compared patient backgrounds between the patients with and without recurrence. Results: Prolapse recurred in 10 of 91 patients (11.0%, and all patients with recurrence were diagnosed as POP-Q stage II. As adverse events, only mesh erosion occurred in two (2.2% and pelvic pain in one (1.1% of the 91 patients. The OABSS and P-QOL were significantly improved by the operation. When we compared patient backgrounds between the patients with and without recurrence, body mass index was the only factor influencing affecting recurrence. Conclusions: Transvaginal minimal mesh repair resulted in successful outcomes with low mesh-related complications and anatomic recurrence at one year. Furthermore, significant improvement in QOL was offered by this procedure. Our minimal mesh technique should be considered as one treatment option for the management of POP.

2016-07-01

Full Text Available Coronary angiogram in a young man with history of STEMI with delayed presentation revealed subtotal occlusion of left anterior descending artery (LAD with large thrombotic filling defect distal to the critical lesion. PCI was preferred without delay because of ongoing chest pain. Several runs of thrombus aspiration failed to detect any visible thrombus. However, the immediate angiogram after thrombus aspiration showed complete distal embolization of the thrombus which could have been achieved by Dottering or balloon dilatation. In contrary to the general perception, does thrombus aspiration push more thrombus than it can aspirate?

We performed percutaneous aspiration followed by injection of 20% hypertonic saline solution into 16 hydatid cysts in 13 patients. All the patients received oral albendazole (400 mg/12 hours) starting 2 days before and lasting until there weeks after the procedure. There were no anaphylactic reactions during or after the procedure. Follow-up included monthly ultrasound over a period ranging between 10 and 36 months. Three cysts disappeared completely; in 10 cases, the cysts cavity was replaced by a complex ultrasonographic findings, with strong signals similar to those of a pseudotumor. In another case, the aspirate was sterile and its morphology remained unchanged. In two cases, infection of the cyst ensued, requiring surgical treatment. We consider that percutaneous aspiration in combination with albendazole may prove to be a good alternative to surgery for the management of hepatic hydatid disease. (Author) 15 refs

The aim of this study was to explore the nature and rate of surgical intervention after transvaginal Prolift mesh repair for pelvic organ prolapse. This was a retrospective study of all patients who underwent Prolift mesh repair between January 2005 and January 2009. Patient data were obtained from medical records, and patients were telephoned to check if they had surgery in other hospitals. A total of 600 consecutive patients were identified. Of these, 524 patients (87.3%) were included in the study, with a median follow-up duration of 38 months (range, 15-63). Global reoperation rate was 11.6%. Indications of intervention were surgery for urinary incontinence (6.9%), mesh-related complications (3.6%), or prolapse recurrence (3%). The global reoperation rate after transvaginal Prolift mesh repair was 11.6%, with urinary incontinence surgery being the most common indication. Rates of mesh complications and prolapse recurrence are relatively low in an experienced team. Copyright © 2012 Mosby, Inc. All rights reserved.

Coronary angiogram in a young man with history of STEMI with delayed presentation revealed subtotal occlusion of left anterior descending artery (LAD) with large thrombotic filling defect distal to the critical lesion. PCI was preferred without delay because of ongoing chest pain. Several runs of thrombus aspiration failed to detect any visible thrombus. However, the immediate angiogram after thrombus aspiration showed complete distal embolization of the thrombus which could have been achieved by Dottering or balloon dilatation. In contrary to the general perception, does thrombus aspiration push more thrombus than it can aspirate? Copyright © 2016 Cardiological Society of India. Published by Elsevier B.V.

The objective of this study was to assess outcomes in native tissue (NT) and transvaginal mesh (TVM) repair in women with recurrent prolapse. A retrospective two-group observational study of 237 women who underwent prolapse repair after failed NT repair in two tertiary hospitals. A primary outcome of "success" was defined using a composite outcome of no vaginal bulge symptoms, no anatomical recurrence in the same compartment beyond the hymen (0 cm on POPQ) and no surgical re-treatment for prolapse in the same compartment. Secondary outcomes assessed included re-operation for prolapse in the same compartment, dyspareunia and mesh-related complications. Of a total of 336 repairs, 196 were performed in the anterior compartment and 140 in the posterior compartment. Compared with the TVM groups, women undergoing repeat NT repair were more likely to experience anatomical recurrence (anterior 40.9 % vs 25 %, p = 0.02, posterior 25.3 % vs 7.5 %, p = 0.01), report vaginal bulge (anterior 34.1 % vs 12 %, p mesh exposure were 9.3 % anteriorly and 15.1 % posteriorly. Although the number of women requiring a prolapse re-operation is lower in the TVM group, the overall re-operation rate was not significantly different when procedures to correct mesh complications were included. Although the success rate is better with the use of TVM for recurrent prolapse, the total re-operation rates are similar when mesh complication-related surgeries are included.

Full Text Available Objective. To evaluate accuracy of transvaginal sonography (TVS and hysteroscopy in detection of intrauterine pathology in infertile women. Subjects and methods. This retrospective study was conducted in 56 infertile women with abnormal transvaginal ultrasound findings of the uterine cavity which was performed during the midfollicular phase as a part of routine infertility workup. Hysteroscopy was performed between 6th and 10th day of cycle. Results. The mean age of the subjects was 31.9±4.0. The most frequent ultrasound finding was endometrial polyp in 34 (60.7% patients, septate uterus in 8 (14.3% patients, submucosal myoma in 7 (12.5% patients, endometrial hyperplasia in 5 (8.9% patients and Syndroma Ascherman in 2 (3.6% patients. Hysteroscopy confirmed 20 (35.7% polyps, the same number of myomas, septate uterus and Syndroma Ascherman as detected by ultrasound, (7 (12.5%, 8 (14.3% and 2 (3.6%, respectively and 19 (33.9% endometrial hyperplasia. In 46 women with histological excamination, the sensitivity of TVS and hysteroscopy in the diagnosis of endometrial polyps were identical - 100%, while the specificity was higher in hysteroscopy than in TVS (92.3% versus 56.4%, p<0.001. The sensitivity of TVS in the diagnosis of endometrial hyperplasia was higher than that of hysteroscopy (86.4% versus 22.7%, p<0.001, while specificity was identical, of 100%. Accordance between hysteroscopy and histology was good (k=0.79, between ultrasound and histology was moderete (k=0.59. Conclusion. Hysteroscopy appeared to be more reliable in diagnosis than TVS. The use of a high frequency ultrasound probe leads us to a lack of diagnostic clarity between endometrial polyps and hyperplasia.

To assess whether cesarean delivery changes the natural position of the uterus. In this retrospective Institutional Review Board-approved cohort study, we conducted a search of our university gynecologic ultrasonography (US) database. Patients with transvaginal US images before and after either vaginal or cesarean delivery between 2012 and 2015 were included. Women with prior cesarean delivery were excluded. Two readers independently measured antepartum and postpartum flexion angles between the longitudinal axis of the uterine body and the cervix. We calculated intraclass correlation coefficients to measure inter-reader agreement. Antepartum and postpartum uterine flexion angles were compared between patients with vaginal and cesarean delivery. We included 173 patients (107 vaginal and 66 cesarean delivery). The mean interval between scans ± SD was 18 ± 10 months. Inter-reader agreement for flexion angles was almost perfect (intraclass correlation coefficients: antepartum, 0.939; postpartum, 0.969; both P cesarean delivery (154.8° ± 45.7°) versus vaginal delivery (145.8° ± 43.7°; P = .216). Mean postpartum flexion angles were higher after cesarean delivery (180.4° ± 51.2°) versus vaginal delivery (152.8° ± 47.7°; P = .001. Differences in antepartum and postpartum flexion angles between cesarean and vaginal delivery were statistically significant (25.6° versus 7.0°; P = .027). Cesarean delivery can change the uterine flexion angle to a more retroflexed position. Therefore, all women with a history of cesarean delivery should undergo a transvaginal US examination before any gynecologic surgery or intrauterine device placement to reduce the possibility of surgical complications. © 2017 by the American Institute of Ultrasound in Medicine.

Rates of ventilator-associated pneumonia (VAP) are highest among patients intubated on an emergency basis following trauma. We reported previously a retrospective analysis demonstrating an association between subjective aspiration and VAP after pre-hospital intubation. We hypothesize that by directing paramedics to note features of aspiration at intubation, we will confirm prospectively the association between pre-hospital aspiration and subsequent pneumonia in trauma patients. Paramedics collected data regarding aspiration at the time of intubation. All intubated patients admitted to a level 1 trauma center intensive care unit (ICU) were included. Data comprised a clinical impression of pre-hospital aspiration, as well as the presence and timing of blood and emesis in the airway. Injury severity, co-morbidities, and outcomes were collected from the trauma registry. Healthcare-associated pneumonia (HAP) was identified by medical record review of both bronchoalveolar lavage culture results and discharge diagnosis. Descriptive statistics and univariate analysis of outcomes by aspiration status, as well as covariable adjustment using propensity scores, were performed. Of the 228 patients, 89 (39%) were determined by paramedics to have aspirated. The majority of those who aspirated (84 [94%]) did so prior to intubation. Patients who aspirated had higher Injury Severity Scores than those who did not aspirate (25.0 ± 1.7 vs. 21.9 ± 1.5 points; p=0.04) and lower preintubation Glasgow Coma Scale scores (8.2 ± 0.50 vs. 9.6 ± 0.40; p=0.02). Of the 89 patients who aspirated around the time of intubation, 14 (16%) developed HAP vs. five (3.6%) of those who did not aspirate (paspiration (deaths: 21 [23.6%] vs. 23 [16.6%]; p=0.19; ICU LOS: 5.3 ± 0.9 vs. 4.1 ± 0.5 days; p=0.13; duration of mechanical ventilation: 5.3 ± 1.2 vs. 3.2 ± 0.5 days; p=0.10). Aspiration prior to intubation was reported commonly by paramedics and was associated with a higher risk of HAP.

A low-hemolysis blood aspirator conserves blood during surgery.

Blood damage caused by traditional vacuum-operated suction tubes, particularly when air is aspirated along with the blood, usually exceeds damage from all other components. In addition to platelet injury, there is a high degree of hemolysis, which leads to high plasma hemoglobin levels and reduces the number of red blood cells available for reinfusion during cases of blood conservation, such as autologous transfusion and cardiac bypass. This work was undertaken to minimize hemolysis, and the accompanying platelet destruction, during aspiration, with the design of a jet-driven aspirator that separates and removes air from blood immediately within the suction tip. The jet-driven aspirator can suction blood at a range of rates from 100 to at least 700 ml/min, separates and removes 80-100% of aspirated air, operates at any orientation, and generates subatmospheric pressures on the order of only 1 inch H2O. In-vitro hemolysis testing showed a significant reduction in average plasma hemoglobin release, from 19.4 mg/dl to 1.8 mg/dl, when air was removed during blood aspiration. In comparative testing with a conventional vacuum suction tube, the jet-driven aspirator showed significantly less hemolysis than the conventional aspirator at comparable rates of air and blood aspiration.

Full Text Available Massive aspiration of food is rare, but most common in people under the influence of alcohol or a drug and comatose patients who have impaired functioning of the central nervous system. The finding of small amounts of food material in the airway at autopsy does not indicate the true vital aspiration because of agonal or even early post-mortem overspills. Occlusion of the small airways, mainly the membranous and respiratory bronchioles, partial or total filling of bronchiolar lumen and the alveolar spaces with food or gastric content were typical morphologic findings. In our 10 year retrospective study we presented the data of 21 male and 4 female cases with a final diagnosis of fatal aspiration in age from 23 to 78 years (45.43±14.61 from the records of Morgue Specialization Department of the Council of Forensic Medicine. 13 cases found death at the scene without an eyewitness. All deaths were accidental in manner except one homicide. Toxicological analysis revealed blood alcohol concentration levels between 161 and 339 mg/dL in 7 cases. Morphine metabolites, benzodiazepine and barbituric acid derivatives, toluene and acetone were detected in 5 subjects. Aspirated materials were food in 14 cases, chewing gum in 3 cases, gastric content in 7 cases and a fabric gag in one case. The history, other evidence of external vomit on the clothing or immediate surroundings and toxicological analysis are by no means as significant as autopsy findings especially in cases of aspiration.

The cytologic and histologic findings from two cases of perineal nodular indurations observed in two cyclists are reported. These lesions, also referred to as "accessory testicles" or "third testicle" or "ischial hygromas" of cyclists, consist of a localized aseptic area of necrosis with pseudocyst formation involving connective tissue in the superficial fascia of the perineum. These histologic findings, which were seen in the subsequent surgical specimens in these two cases, were reflected in the fine needle aspiration findings. The aspirates contained few cellular elements, mainly a few vacuolated histiocytes, against a background of fibrinous material. These indurations, which develop as a result of repeated, chronic microtrauma to the perineum impressed by the vibration of the saddle of the bicycle, constitute an authentic handicap for the professional cyclist and are a contraindication to cycling for amateur cyclists.

Although prior research finds a robust link between delinquent behavior and expectations, or an adolescent's perceived likelihood of obtaining one's future goals, fewer studies have evaluated aspirations, or the perceived importance of achieving one's goals. In addition, few studies consider how individual traits such as impulsivity affect the degree to which expectations and aspirations motivate or deter delinquent behavior. We contribute to this body of research by evaluating the independent effects of expectations and aspirations, and the aspiration-expectation gap (i.e., strain) on delinquent behavior during the year following an adolescent's first arrest using a large (N = 1117), racially/ethnically diverse sample of male adolescents (46.55% Latino, 35.81% Black, 14.95% White, and 2.69% Other race). In addition, we considered how impulse control interacts with expectations, aspirations, and strain to motivate behavior. Our results indicated that both aspirations, expectations and strain uniquely influence criminal behavior. Importantly, aspirations interacted with impulse control, such that aspirations affected delinquency only among youth with higher impulse control. Our findings suggest that aspirations may only influence behavior if youth also have the psychosocial capabilities to consider their future aspirations when behaving in the present.

Full Text Available Aspiration pneumonia is a dominant form of community-acquired and healthcare-associated pneumonia, and a leading cause of death among ageing populations. However, the risk factors for developing aspiration pneumonia in older adults have not been fully evaluated. The purpose of the present study was to determine the risk factors for aspiration pneumonia among the elderly.We conducted an observational study using data from a nationwide survey of geriatric medical and nursing center in Japan. The study subjects included 9930 patients (median age: 86 years, women: 76% who were divided into two groups: those who had experienced an episode of aspiration pneumonia in the previous 3 months and those who had not. Data on demographics, clinical status, activities of daily living (ADL, and major illnesses were compared between subjects with and without aspiration pneumonia. Two hundred and fifty-nine subjects (2.6% of the total sample were in the aspiration pneumonia group. In the univariate analysis, older age was not found to be a risk factor for aspiration pneumonia, but the following were: sputum suctioning (odds ratio [OR] = 17.25, 95% confidence interval [CI]: 13.16-22.62, p < 0.001, daily oxygen therapy (OR = 8.29, 95% CI: 4.39-15.65, feeding support dependency (OR = 8.10, 95% CI: 6.27-10.48, p < 0.001, and urinary catheterization (OR = 4.08, 95% CI: 2.81-5.91, p < 0.001. In the multiple logistic regression analysis, the risk factors associated with aspiration pneumonia after propensity-adjustment (258 subjects each were sputum suctioning (OR = 3.276, 95% CI: 1.910-5.619, deterioration of swallowing function in the past 3 months (OR = 3.584, 95% CI: 1.948-6.952, dehydration (OR = 8.019, 95% CI: 2.720-23.643, and dementia (OR = 1.618, 95% CI: 1.031-2.539.The risk factors for aspiration pneumonia were sputum suctioning, deterioration of swallowing function, dehydration, and dementia. These results could help improve clinical management for preventing

6% of all patients suffering from a cerebro-vascular injury die from aspiration pneumonia within the first year. The high temporal resolution of high-speed cineradiography (HFK) (50 frames/sec.) allows the recording of the 0.7 sec. process of pharyngeal swallow. Five case-examples are presented (total number of cases: 95) illustrating the possibility of differentiation between three types of aspiration by means of cineradiography. These types are the so-called pre-, intra- and postdeglutitive aspiration, that is aspiration before or after triggering of the swallowing reflex. This differentiation is of great therapeutic importance. The analysis of disturbances of pharyngo-laryngeal motility and the temporal coordination allows setting up individual surgical and/or conservative programme for rehabilitation. (orig.) [de

Full Text Available Abstract Foreign body aspiration continues to be a serious problem in childhood and adolescent period with significant rate of morbidity and rarely mortality. Half of the foreign body aspiration cases have no history of aspiration. The main foreign bodies inhaled are food fragments and different kinds of metallic objects. A 12-year-old girl was referred to the pediatric pulmonology department for chronic cough and hemoptysis. She had persistent infiltration and cavitary lesion mimicking cavitary tuberculosis. There was no contact history with tuberculosis in her family and acid resistant bacillus was not found in the sputum examination. Flexible bronchoscopy was performed for persistent infiltration and hemoptysis and inflamed thread was found in right lower lobe bronchus. This is the first case of thread inhalation mimicking cavitary tuberculosis in an adolescent patient.

Urethral injury resulting from transvaginal mesh slings is a rare complication with an estimated incidence of surgical management and functional outcomes of women presenting with urethral mesh perforation following midurethral sling (MUS) placement. This was a retrospective multicenter review of women who from January 2011 to March 2016 at two institutions underwent mesh sling excision for urethral perforation with Female Pelvic Medicine and Reconstructive Surgery fellowship-trained surgeons. Data comprising preoperative symptoms, operative details, and postoperative outcomes were collected by telephone (n 13) or based on their last follow-up appointment. Nineteen women underwent transvaginal sling excision for urethral mesh perforation. Eight (42%) patients had undergone previous sling revision surgery. Sixty percent of women had resolution of their pelvic pain postoperatively. At follow-up, 92% reported urinary incontinence (UI), and three had undergone five additional procedures for vaginal prolapse mesh exposure (n 1), incontinence (onabotulinum toxin injection n 1, rectus fascia autologous sling n 1), prolapse (colpopexy n 1), and pain (trigger-point injection n 1). Patient global impression of improvement data was available for 13 patients, of whom seven (54%) rated their postoperative condition as Very much better or Much better. The management of urethral mesh perforation is complex. Most women reported resolution of their pelvic pain and a high rate of satisfaction with their postoperative condition despite high rates of incontinence.

Pelvic organ prolapse (POP) is a common disease in women. The aim of this research was to evaluate the safety, efficacy and complication of transvaginal modified sacrospinous ligament fixation with mesh using for the treatment of vaginal vault prolapse. This was a prospective study including information from 60 symptomatic women with anterior-apical pelvic floor prolapse. The patients underwent transvaginal modified sacrospinous ligament fixation combined with anterior vaginal wall mesh between May 2014 and Sep 2015. The perioperative data including clinical characteristic, operation time, blood loss, and surgical complications were collected at 1 year and 2 years. During a 2-year follow-up, the primary outcome evaluation included Pelvic organ prolapse Quantification system (POP-Q), Incontinence Quality of Life scale (I-QoL), the Prolapse/Urinary Incontinence Sexual Questionnaire (PISQ-12) and the Pelvic Floor Distress Inventory, short form 20 (PFDI-20). The mean follow-up time was 2 years (range 24-37 months). The patients' mean age was 66.75 ± 6.44. Of 60 patients who were enrolled in this research, 26 patients had severe stress urinary incontinence (SUI). The mean operation time was 99.14 ± 19.60 min and the mean estimated blood loss was 73.83 ± 41.05 ml. The rate of anatomical success was 98.3% and one patient had a recurrence. The POP-Q point measurements were evaluated preoperatively and postoperatively (P transvaginal modified sacrospinous ligament fixation with mesh might be performed easily and might be a safe surgery for elderly patients whose requirements for sexual life were relatively low.

2016-12-01

Cervical auscultation (CA) may be used to complement feeding/swallowing evaluations when assessing for aspiration. There are no published pediatric studies that compare the properties of sounds between aspirating and nonaspirating swallows. To establish acoustic and perceptual profiles of aspirating and nonaspirating swallow sounds and determine if a difference exists between these 2 swallowing types. Aspiration sound clips were obtained from recordings using CA simultaneously undertaken with videofluoroscopic swallow study. Aspiration was determined using the Penetration-Aspiration Scale. The presence of perceptual swallow/breath parameters was rated by 2 speech pathologists who were blinded to the type of swallow. Acoustic data between groups were compared using Mann Whitney U-tests, while perceptual differences were determined by a test of 2 proportions. Combinations of perceptual parameters of 50 swallows (27 aspiration, 23 no aspiration) from 47 children (57% male) were statistically analyzed using area under a receiver operating characteristic (aROC), sensitivity, specificity, and positive and negative predictive values to determine predictors of aspirating swallows. The combination of post-swallow presence of wet breathing and wheeze and absence of GRS and normal breathing was the best predictor of aspiration (aROC = 0.82, 95% CI, 0.70-0.94). There were no significant differences between these 2 swallow types for peak frequency, duration, and peak amplitude. Our pilot study has shown that certain characteristics of swallow obtained using CA may be useful in the prediction of aspiration. However, further research comparing the acoustic swallowing sound profiles of normal children to children with dysphagia (who are aspirating) on a larger scale is required. © The Author(s) 2016.

FOREIGN BODY ASPIRATION: A CASE REPORT

Full Text Available Foreign body aspiration (FBA is common under 3 years of age. FBA can cause sudden respiratory failure. Furthermore, it leads to many respiratory system complications. Therefore, FBA is an important cause of mortality and morbidity for this age group. FBA cases are usually followed by diagnoses like pneumonia, bronchitis or bronchial asthma in the late period that history, clinical and laboratory findings suggesting foreign body aspiration can not be detected. We reported a 2-year-old male patient with pneumonia, who were administered various treatments. In thorax CT of this case, an image compatible with foreign body was seen in the right middle lobe-upper lobe separation area. Granulation tissue was detected in the entrance of the right main bronchus by rigid bronchoscopy and marked improvement occured in lung aeration after bronchoscopy. This case was reported to emphasize the importance of early diagnosis of foreign body aspiration because of high mortality and morbidity and the necessity of considering the foreign body aspiration in children with recurrent pulmonary infections.

Jae Jun Lee

2017-02-01

Full Text Available A 74-year-old man presented with recurrent vomiting and aspiration pneumonia in the left lower lobe. He entered the intensive care unit to manage the pneumonia and septic shock. Although a percutaneous endoscopic gastrostomy tube was implanted for recurrent vomiting, vomiting and aspiration recurred frequently during admission. Subsequently, he complained of neck pain when in an upright position. A videofluoroscopic swallowing study showed compression of the esophagus by cervical osteophytes and tracheal aspiration caused by an abnormality at the laryngeal inlet. Cervical spine X-rays and computed tomography showed anterior cervical osteophytes at the C3-6 levels. Surgical decompression was scheduled, but was cancelled due to his frailty. Unfortunately, further recurrent vomiting and aspiration resulted in respiratory arrest leading to hypoxic brain damage and death. Physicians should consider cervical spine disease, such as diffuse skeletal hyperostosis as an uncommon cause of recurrent aspiration pneumonia.

Parkinson's disease (PD) patients show a high prevalence of swallowing disorders and tracheal aspiration of food. The videofluoroscopic study of swallowing (VFSS) allows clinicians to visualize the visuoperceptual and temporal parameters associated with swallowing disorders in an attempt to predict aspiration risk. However, this subject remains understudied in PD populations. Our aim was to identify the predictors of penetration-aspiration in PD patients using the VFSS. Consecutive patients were evaluated using VFSS with different consistencies and volumes of food. A speech-language pathologist measured the type of intra-oral bolus organization, loss of bolus control, bolus location at the initiation of the pharyngeal swallow, the presence of multiple swallows, piecemeal deglutition, bolus residue in the pharyngeal recesses and temporal measures. Scores ≥3 on the penetration-aspiration scale (PAS) indicated the occurrence of penetration-aspiration. Using logistic marginal regression, we found that residue in the vallecula, residue in the upper esophageal sphincter and piecemeal deglutition were associated with penetration-aspiration (odds ratio (OR) = 4.09, 2.87 and 3.83; P = 0.0040, 0.0071 and 0.0009, respectively). Penetration/aspiration occurred only with fluids (both of thin and thick consistency), and no significant differences were observed between fluid types or food volumes. The mechanisms underlying dysphagia and penetration/aspiration in PD patients and indications for further studies are discussed.

Aspiration pneumonias occur more frequently than reported and, in many cases, the disease is not recognised. In hospitalised and institutionalised patients with predisposing diseases prompt diagnosis of this complication and correct preventive measures can drastically reduce the worsening of clinical conditions and the deaths due to aspiration pneumonia. Normal airway structure, effective defence mechanisms, and preventive measures are decisive in reducing aspiration episodes. An increased aspiration risk for food, fluids, medications, or secretions may lead to the development of pneumonia. Pneumonia is the most common respiratory complication in all stroke deaths and in mechanical ventilation patients. In addition, the increased incidence of aspiration pneumonia with aging may be a consequence of impairment of swallowing and the cough reflex. Dysphagia, compromised consciousness, invasive procedures, anaesthesia, insufficient oral care, sleep disorders, and vomiting are all risk factors. Aspiration pneumonia includes different characteristic syndromes based on the amount (massive, acute, chronic) and physical character of the aspirated material (acid, infected, lipoid), needing a different therapeutic approach. Chronic patients education and correct health care practices are the keys for preventing the events of aspiration. In patients at risk a clinical and instrumental assessment of dysphagia should be evaluated. Management includes the removal of etiologic factors (drugs, tubes, mobilisation, oral hygiene), supportive care, and in bacterial pneumonias a specific antibiotic therapy for community-acquired or nosocomial events.

Transvaginal(TV) sonography uses high-frequency transducer and allows access to the uterus and adnexa, provides better resolution and more accurate diagnosis of ectopic pregnancy. To determine the value and the utility of TV sonography for a suspected ectopic pregnancy, we studied 56 women during 4 months from January to April 1989. Of 56 patients 46 had an surgically confirmed ectopic pregnancy, 5 had not an ectopic pregnancy and 5 had not follow up. TV sonography provides definite sonographic diagnosis of ectopic pregnancy including an extrauterine gestational sac 34 cases(74%), extrauterine embryo 9 caes(19.7%), hematosalpinx 10 cases(21.7%). Overall adnexal mass was detected in 38 cases(82.6%) at initial TV sonography and in 44 cases(95.6%) at follow up TV sonography. Additional findings were uterine decidual reaction 19 cases(41.3%), pseudo G-sac 4 cases(8.7%), cul-de-sac fluid 42 cases(91.2%). Follow-up TV sonography showed newly developed or growing adnexal mass in 8 among 9 cases. False positive 5 cases were two ovarian cysts, one incomplete abortion, two parametrial thickening due to previous ectopic pregnancy and salpingectomy. TV sonography may improve the govality of patient management by early diagnosis and early surgical treatment, so may preserve fertility. In conclusion, we may suggest that TV sonography is an integral part of diagnostic modality in suspected ectopic pregnancy.

In order to elucidate the correlation of gastroesophageal reflex (GER) with aspiration pneumonia after surgery, 48 patients (mean, 75.6 years) with gastric cancer treated at the hospital from March, 1994 to December, 1994 were subjected to this prospective study. The pharyngeal stimulation test, nutritional assessment, radionuclide esophageal scintigraphy (34 cases) were performed before surgery and relationship between those results and aspiration pneumonia were studied. Aspiration pneumonia occurred in 3 cases, and all of them were in, significantly, poor nutritional status, compared with other. A significant increase in the frequency of GER was observed when a naso-gastric tube (NGT) was placed, but surprisingly, all the patients with aspiration pneumonia were 3 out of 4 patients who had continuous GER without NGT. It is noteworthy, continuous GER without NGT was significantly (p<0.001) affected postoperative aspiration pneumonia and impaired phalyngeal reflex was frequently correlated with development of aspiration pneumonia, when malnutritional status existed.

Transvaginal mesh anterior-posterior (TVM-AP) provides better cure rates in the surgical treatment of vaginal cuff eversion than anterior transvaginal mesh combined with sacrospinous ligament fixation (TVM-A). We determine the outcomes after TVM-A and TVM-AP surgeries in advanced vaginal cuff prolapse. The charts of 796 women who underwent pelvic organ prolapse (POP) surgery from July 2006 to January 2012 in Chang Gung Memorial Hospitals were reviewed. We included women who presented with advanced cuff eversion and treated with TVM surgery. Data were analysed after three years post-surgery. Descriptive statistics were used for demographic and perioperative data. The paired-samples t test was used for comparison of preoperative and postoperative continuous data. The outcomes measured were objective cure (POP-Q stage ≤ 1) and subjective cure (negative response to question 2 and 3 on POPDI-6). A total of 97 patients was analysed. 61 patients had TVM-A and 36 patients had TVM-AP insertion. Mean follow-up was 52 months. The objective cure rate for TVM-AP was significantly higher than TVM-A, 94.4% versus 80.3%. TVM-AP also showed a higher subjective cure rate (91.7%) though there was no significant difference from TVM-A (p = 0.260). The mesh extrusion rate was low at 3.1% with no major complications seen. In TVM-A the blood loss was lesser and the operation time was shorter. TVM-AP showed better objective cure rate than TVM-A at 52 months. However, TVM-A is less invasive in comparison with an acceptably good cure rates. Copyright © 2017. Published by Elsevier B.V.

Aspiration Risk and Respiratory Complications in Patients with Esophageal Atresia.

Science.gov (United States)

Kovesi, Thomas

2017-01-01

Chronic, long-term respiratory morbidity (CRM) is common in patients with a history of repaired congenital esophageal atresia, typically associated with tracheoesophageal fistula (EA/TEF). EA/TEF patients are at high risk of having aspiration, and retrospective studies have associated CRM with both recurrent aspiration and atopy. However, studies evaluating the association between CRM in this population and either aspiration or atopy have reported conflicting results. Furthermore, CRM in this population may be due to other related conditions as well, such as tracheomalacia and/or recurrent infections. Aspiration is difficult to confirm, short of lung biopsy. Moreover, even within the largest evidence base assessing the association between CRM and aspiration, which has evaluated the potential relationship between gastroesophageal reflux and asthma, findings are contradictory. Studies attempting to relate CRM to prior aspiration events may inadequately estimate the frequency and severity of previous aspiration episodes. There is convincing evidence documenting that chronic, massive aspiration in patients with repaired EA/TEF is associated with the development of bronchiectasis. While chronic aspiration is likely associated with other CRM in patients with repaired EA/TEF, this does not appear to have been confirmed by the data currently available. Prospective studies that systematically evaluate aspiration risk and allergic disease in patients with repaired EA/TEF and document subsequent CRM will be needed to clarify the causes of CRM in this population. Given the prevalence of CRM, patients with repaired EA/TEF should ideally receive regular follow-up by multidisciplinary teams with expertise in this condition, throughout both childhood and adulthood.

The CRISPR-Cas (clustered regularly interspaced short palindromic repeat-CRISPR-associated protein) system is unique to prokaryotes and provides the majority of bacteria and archaea with immunity against nucleic acids of foreign origin. CRISPR RNAs (crRNAs) are the key element of this system, since they are responsible for its selectivity and effectiveness. Typical crRNAs consist of a spacer sequence flanked with 5' and 3' handles originating from repeat sequences that are important for recognition of these small RNAs by the Cas machinery. In this investigation, we studied the type I-C CRISPR-Cas system in Porphyromonas gingivalis , a human pathogen associated with periodontitis, rheumatoid arthritis, cardiovascular disease, and aspiration pneumonia. We demonstrated the importance of the 5' handle for crRNA recognition by the effector complex and consequently activity, as well as secondary trimming of the 3' handle, which was not affected by modifications of the repeat sequence. IMPORTANCE Porphyromonas gingivalis , a clinically relevant Gram-negative, anaerobic bacterium, is one of the major etiologic agents of periodontitis and has been linked with the development of other clinical conditions, including rheumatoid arthritis, cardiovascular disease, and aspiration pneumonia. The presented results on the biogenesis and functions of crRNAs expand our understanding of CRISPR-Cas cellular defenses in P. gingivalis and of horizontal gene transfer in bacteria.

To explore the clinicopathological characteristics of aspiration pneumonia in the elderly. The clinical data of 30 cases of autopsy-proven aspiration pneumonia in Beijing Hospital from 1973 to 2002 were reviewed. The patients consisted of 28 males and 2 females, aged from 63 to 103 [mean (83 ± 9)] years. Only 15 cases were clinically diagnosed as aspiration pneumonia before death. Concomitant diseases were severe and complex, mostly coronary disease, cerebrovascular disease, hypertension, COPD, and diabetes mellitus. All the patients suffered from at least 3 concomitant diseases. Long-term bedridden and nasogastric feeding was seen in 11 and 17 patients respectively. The clinical presentation and chest X-ray of aspiration pneumonia in the elderly were nonspecific and variable. Mixed infections were common . The main bacteria isolated were Gram-negative bacilli, in particular Pseudomonas aeruginosa, Stenotrophomonas maltophilia, Escherichia coli and Candida albicans. By pathology, macrophages with foreign bodies were found in all the 30 cases and multiple small abscesses were found in 14 cases. The lesions were adjacent to the bronchioles and in the lung tissue around the bronchioles, mostly multi-lobar and bilateral. Unilateral or bilateral pleural effusion developed in 20 patients. The accordance between radiological and pathological diagnosis of aspiration pneumonia was very poor. The foci of infection detected by X-ray were proven by autopsy in 13 patients, while pleural effusions in X-ray were proven by autopsy in 15 patients. Multi-concomitant diseases, mixed infection and extra-pulmonary presentations were common in elderly patients with aspiration pneumonia. Multiple small abscesses were the pathological characteristics of aspiration pneumonia in the aged. A definite clinical diagnosis of aspiration pneumonia was difficult. Recurrent silent microaspiration was a feature of aspiration in the elderly. The assessment of risk factor of aspiration played an

Fine needle aspiration cytology of cervicofacial actinomycosis

Full Text Available Actinomycosis is a chronic infection caused by Actinomyces israelii, usually seen in immunocompromised patients or in the background of tissue injury. Cervicofacial actinomycosis presenting as a fixed jaw swelling in an elderly individual can mimic malignancy and pose a diagnostic dilemma. We report here a case of cervicofacial actinomycosis diagnosed by fine needle aspiration, along with a review of the relevant literature. A 60 year-old man presented with a gradually increasing 6 x 5 cm swelling in the left side of his jaw. The swelling was fixed, without any apparent sinus or abscess. Fine needle aspiration was diagnostic as it revealed colonies of actinomyces surrounded by polymorphs and chronic inflammatory cells. The histopathological study of the excised specimen confirmed the cytological findings. Fine needle aspiration is an effective tool in the diagnosis of actinomycosis although its documentation is rare. Difficulties in the management can be avoided by early diagnosis using the fine needle aspiration technique.

The AstroBiology Explorer (ABE) and the Astrobiology Space InfraRed Explorer (ASPIRE) Mission Concepts are two missions designed to address the questions (1) Where do we come from? and (2) Are we alone? as outlined in NASA s Origins Program using infrared spectroscopy to explore the identity, abundance, and distribution of molecules of astrobiological importance throughout the Universe. The ABE mission s observational program is focused on six tasks to: (1) Investigate the evolution of ice and organics in dense clouds and star formation regions, and the young stellar/planetary systems that form in them; (2) Measure the evolution of complex organic molecules in stellar outflows; (3) Study the organic composition of a wide variety of solar system objects including asteroids, comets, and the planets and their satellites; (4) Identify organic compounds in the diffuse interstellar medium and determine their distribution , abundance, and change with environment; (5) Detect and identify organic compounds in other galaxies and determine their dependence on galactic type; and (6) Measure deuterium enrichments in interstellar organics and use them as tracers of chemical processes. The ASPIRE mission s observational program expands upon ABE's core mission and adds tasks that (7) Address the role of silicates in interstellar organic chemistry; and (8) Use different resolution spectra to assess the relative roles and abundances of gas- and solid-state materials. ABE (ASPIRE) achieves these goals using a highly sensitive, cryogenically-cooled telescope in an Earth drift-away heliocentric orbit, armed with a suite of infrared spectrometers that cover the 2.5-20(40) micron spectral region at moderate spectral resolution (R>2000). ASPIRE's spectrometer complement also includes a high-resolution (R>25,000) module over the 4-8 micron spectral region. Both missions target lists are chosen to observe a statistically significant sample of a large number of objects of varied types in

Objective: Detecting and assessment the corpus luteum blood flow in normal and abnormal early pregnancy. Methods: Using transvaginal color and pulse Doppler sonography, we detected 215 pregnant women including 150 normal intrauterine pregnancies, 25 abortion, 29 ectopic pregnancies, and then recorded corpus luteum blood flow feature and the blood flow indexes (Vmax, RI and PI). Results: 1) Corpus luteum was successfully identified in 148 cases out of 150 of normal early pregnancies, 25 cases out of 26 of threatened abortion; 22 cases out of 29 of ectopic pregnancy. 2) Three groups shared the same feature of Color Doppler imaging: a circumferential rim around the entire corpus luteum. 3) The flow index revealed mean PVS, RI and PI had no statistical difference in normal and abnormal early pregnancy; The mean PVS was lower in ectopic pregnancy than in normal pregnancy (P<0.05), while PI and PR had no characteristic in ectopic pregnancy group compared with the indexes obtained in normal pregnancy group. Conclusion: The corpus luteum can be precisely identified in most pregnancy using transvaginal color Doppler and manifests a characterized rim Doppler imaging. PVS may help in differentiating the ectopic pregnancy from normal early pregnancy. (authors)

2012-06-01

The purpose of this direct replication study was to confirm the incidence of vocal fold immobility (VFI) and its relationship to pharyngeal dysphagia and aspiration. Using a single-group consecutively referred case series, a total of 2,650 participants underwent fiberoptic endoscopic evaluation of swallowing between August 2003 and December 2007. Main outcome measures included overall incidence of VFI and aspiration status, with specific emphasis on age, gender, etiology and pharyngeal phase bolus flow characteristics, and side of VFI (right, left, or bilateral). These data were compared to and then combined with the original study (n = 1,452) for a total of 4,102 participants. Results indicated that the incidence of VFI was 4.3% (112/2,650), i.e., 27% (31/112) unilateral right, 58% (65/112) unilateral left, and 14% (16/112) bilateral. Incidence of aspiration was 22% (580/2,650). Of those with VFI, 40% (45/112) aspirated, i.e., 42% (13/31) unilateral right, 37% (24/65) unilateral left, and 50% (8/16) bilateral. An individual with VFI had 2.50 times the odds of aspirating as someone without VFI (95% CI = 1.86-3.37). For liquid aspiration, the odds ratio (OR) = 2.41 (95% CI = 1.77-3.28), and for puree aspiration, OR = 2.08 (95% CI = 1.47-2.93). Left VFI occurred most frequently due to surgical trauma. Liquid was aspirated more often than a puree. Males exhibited VFI more often than females. Side of VFI and age were not factors that increased the incidence of aspiration significantly. It was confirmed that VFI is not an uncommon finding during dysphagia testing and, when present, increased the odds of aspiration compared to a population already being evaluated for dysphagia.

Although women who highly identify with other women are more susceptible to stereotype threat effects, women's identification might associate with greater leadership aspirations contingent on (1) counter-stereotype salience and (2) feminist identification. When gender counter-stereotypes are salient, women's identification should associate with greater leadership aspiration regardless of feminism, while when gender stereotypes are salient, women's identification would predict greater leadership aspirations contingent on a high level of feminist identification. In our study US-based women (N = 208) attended to gender stereotypic (vs. counter-stereotypic) content. We measured identification with women and identification with feminism, and, following the manipulation, leadership aspirations in an imagined work scenario. The interaction between identification with women, identification with feminism, and attention to stereotypes (vs. counter-stereotypes) significantly predicted leadership aspirations. In the counter-stereotypic condition women's identification associated with greater leadership aspirations regardless of feminist identification. In the stereotypic condition women's identification predicted leadership aspirations only at high levels of feminist identification. We conclude that salient counter-stereotypes and a strong identification with feminism may help high women identifiers increase their leadership aspirations. PMID:28626437

Aspiration dynamics of multi-player games in finite populations.

Science.gov (United States)

Du, Jinming; Wu, Bin; Altrock, Philipp M; Wang, Long

2014-05-06

On studying strategy update rules in the framework of evolutionary game theory, one can differentiate between imitation processes and aspiration-driven dynamics. In the former case, individuals imitate the strategy of a more successful peer. In the latter case, individuals adjust their strategies based on a comparison of their pay-offs from the evolutionary game to a value they aspire, called the level of aspiration. Unlike imitation processes of pairwise comparison, aspiration-driven updates do not require additional information about the strategic environment and can thus be interpreted as being more spontaneous. Recent work has mainly focused on understanding how aspiration dynamics alter the evolutionary outcome in structured populations. However, the baseline case for understanding strategy selection is the well-mixed population case, which is still lacking sufficient understanding. We explore how aspiration-driven strategy-update dynamics under imperfect rationality influence the average abundance of a strategy in multi-player evolutionary games with two strategies. We analytically derive a condition under which a strategy is more abundant than the other in the weak selection limiting case. This approach has a long-standing history in evolutionary games and is mostly applied for its mathematical approachability. Hence, we also explore strong selection numerically, which shows that our weak selection condition is a robust predictor of the average abundance of a strategy. The condition turns out to differ from that of a wide class of imitation dynamics, as long as the game is not dyadic. Therefore, a strategy favoured under imitation dynamics can be disfavoured under aspiration dynamics. This does not require any population structure, and thus highlights the intrinsic difference between imitation and aspiration dynamics.

How useful is gastroesophageal reflux scintigraphy in suspected childhood aspiration?

International Nuclear Information System (INIS)

Fawcett, H.D.; Adams, J.C.; Hayden, C.K.; Swischuk, L.E.

1988-01-01

It has been suggested that gastroesophageal reflux scintigraphy might be useful in assisting one in determining therapy for patients suspected of aspirating or becoming apneic secondary to gastroesophageal reflux. This, however, has not been our experience and in reviewing 23 patients with recurrent pneumonia and/or apnea who had gastroesophageal reflux scintigraphy, we were able to detect aspiration in only one. This was especially significant since 13 (59%) of these patients had demonstrable reflux, and of these, eight were treated successfully for suspected aspiration even though none was demonstrated isotopically. To be sure, the demonstration of pulmonary aspiration with gastroesophageal reflux scintigraphy had little influence on patient selection and response to therapy. For this reason we feel there is little justification in depending on the GRS for the specific purpose of trying to document pulmonary aspiration in infants and children who are refluxing. One of the more serious complications of gastroesophageal (GE) reflux is aspiration leading to recurrent pulmonary infections and/or apnea. However, it always has been difficult to demonstrate actual aspiration into the lungs, and to be sure, barium studies of the upper GI tract seldom reveal this complication. Recently, however, considerable interest has been generated in gastroesophageal scintigraphy (GRS) as a possible means of documenting such aspiration. Rationale for this stems from the fact that suspected patients can be studied over a longer period of time and in addition, delayed and overnight images can be obtained. However, our experience does not support GRS as being an adequate method for demonstrating aspiration. (orig.)

How useful is gastroesophageal reflux scintigraphy in suspected childhood aspiration

It has been suggested that gastroesophageal reflux scintigraphy might be useful in assisting one in determining therapy for patients suspected of aspirating or becoming apneic secondary to gastroesophageal reflux. This, however, has not been our experience and in reviewing 23 patients with recurrent pneumonia and/or apnea who had gastroesophageal reflux scintigraphy, we were able to detect aspiration in only one. This was especially significant since 13 (59%) of these patients had demonstrable reflux, and of these, eight were treated successfully for suspected aspiration even though none was demonstrated isotopically. To be sure, the demonstration of pulmonary aspiration with gastroesophageal reflux scintigraphy had little influence on patient selection and response to therapy. For this reason we feel there is little justification in depending on the GRS for the specific purpose of trying to document pulmonary aspiration in infants and children who are refluxing. One of the more serious complications of gastroesophageal (GE) reflux is aspiration leading to recurrent pulmonary infections and/or apnea.

Full Text Available The aspiration of barium contrast is a rare complication that may occur during studies of the digestive tract. Barium is an inert material that can cause anywhere from an asymptomatic mechanical obstruction to serious symptoms of respiratory distress that can result in patient death. We present the case of a 79-year-old male patient in whom we observed the presence of contrast medium residue in the lung parenchyma as an incidental finding during hospitalization. When the patient’s medical file was reviewed, images were found of a barium swallow study that the patient had undergone months earlier, and we were able to observe the exact moment of the aspiration of the contrast material. The patient had been asymptomatic since the test.

1992-01-01

Between October 1988 and March 1991, 29 patients with endometrial carcinoma had both transvaginal ultrasonography (TVUS) and magnetic resonance imaging (MRI) performed following hysterectomy at the Department of Gynecology and Obstetrics, Okayama University Medical School. The findings were compared with the pathological findings to determine the usefulness of each method. The sensitivity of detecting myometrial invasion was 100% by TVUS and 96% by MRI. The accuracy was 86% by each method. The depth of myometrial invasion was classified into 3 degrees [no myometrial invasion, superficial invasion (≤1/2), deep invasion (>1/2)]. The correct diagnostic rate was 86% by TVUS and MRI. The minimum width and the minimum/maximum width ratio of the intact myometrium obtained by each method in the pathological deep invasion group were significantly lower than those obtained in the other two groups (p<0.01). The sensitivity, the accuracy and the specificity for detecting cervical invasion were 89%, 93% and 95% by both methods. There was no difference between TVUS and MRI for diagnosing myometrial and cervical invasion of endometrial carcinoma. (author)

, such as the damage to the pudendal vessels and nerve, the sciatic nerve and rectum. The possibility of injury to the vessels and nearby nerves was preventid with the careful placement of suture through the sacrospinous ligament in the two fingerbreadths medial to its insertion in the ischial spine. In our series, we had 3 patients with conservation of the uterus. The 3 asymptomatic cystocele in our series were diagnosed 6 months after the operation. Our results were satisfactory, since we hade only one postoperative vault prolapse (2,7%. Conclusion. The results of numerous studies, as well as the results of our study, showed that transvaginal sacrospinous colpopexy could be performed along with vaginal hysterectomy and the anterior and posterior vaginal wall repair in the patients with uterovaginal prolapse because of its high success in the prevention of postoperative vaginal vault prolapse and the low intra- and postoperative complication rates. This operative technique is successful in prevention of repeated vaginal vault prolapse.

Canale, S.T.; Harkness, R.M.; Thomas, P.A.; Massie, J.D.

1985-01-01

To determine the effect, if any, of needle aspiration on /sup 99m/Tc bone scanning, three different areas of 15 dogs were first aspirated and then imaged with technetium bone scintigraphy. The hip joint was aspirated, the distal femoral metaphysis was drilled and aspirated, and the tibial periosteum was scraped with an 18- or 20-gauge needle. Varying amounts of trauma were inflicted to simulate varying difficulties at aspiration. /sup 99m/Tc bone scans were obtained from 5 h to 10 days later. There was no evidence of focal technetium uptake after any hip joint aspiration. This was consistent regardless of the amount of trauma inflicted or the time from aspiration to bone scanning. Metaphyseal cortical drilling and tibial periosteal scraping occasionally caused some focal uptake when scanning was delayed greater than 2 days. When osteomyelitis or pyarthrosis is clinically suspected, joint aspiration can be performed without fear of producing a false- positive bone scan

Aspiration lung disorders in bovines: a case report and review.

Shakespeare, Anthony S

2012-11-01

Lung aspiration disorders in bovines are invariably diagnosed as infectious aspiration pneumonias. There is a distinct differentiation between aspiration pneumonia and aspiration pneumonitis in humans that can be applied to bovines. The nature and quantity of the aspirate can result in differing pathogeneses which can require differing therapeutic approaches. Whilst blood gases were important in detecting and prognosticating lung problems, changes in barometric pressure with altitude have to be considered when interpreting partial pressures of oxygen. Anatomical differences in the lungs of bovines can explain why this species is more prone to certain pneumonic problems. Pulmonary physiotherapy is important in treating lung disorders in humans and should be considered as an adjunct therapy in bovine respiratory conditions. A case work-up was used to highlight some of the points discussed in this article.

Silent aspiration is associated with pneumonia and mortality, and is poorly identified by traditional clinical swallowing evaluation (CSE). The aim of this study was to validate cough reflex testing (CRT) for identification of silent aspiration against aspiration confirmed by instrumental assessment. Cough reflex threshold testing was completed on all patients using inhaled, nebulised citric acid. Within an hour, 80 patients underwent videofluoroscopic study of swallowing (VFSS) and 101 patients underwent fibreoptic endoscopic evaluation of swallowing (FEES). All tests were recorded and analysed by two researchers blinded to the result of the alternate test. Significant associations between CRT result and cough response to aspiration on VFSS (X(2) (2)=11.046, p=.003) and FEES (X(2) (2)=34.079, pacid provide a better predictive measure of silent aspiration.

Full Text Available Background: Post-menopausal hemorrhage is one of the most common complains in gynecologic clinics. More than 60% of these cases have abnormal findings in diagnostic work ups. There is contraversy about the best diagnostic method for evaluating post-menopausal hemorrhage. The aim of this study was to evaluate the results of Trans-Vaginal Ultrasonography and compare its result to ones derived from direct endometrial biopsy and Hysteroscopy findings.Methods: In a cross-sectional study, menopausal women who attended the outpatient clinic of Arash Hospital, Tehran University of medical Sciences, from April 2005 to March 2006 with the complain of hemorrhage were evaluated. In all of these patients, after getting informed consent, Trans-Vaginal Ultrasonography, Dilatation and Curettage and Hysteroscopy were performed.Results: The total number of 90 women was recruited to the study with the age range of 41-80 years. The mean age of participants was 53.84 ± 6 years and 4.3 ± 5.1 years had passed from their menopause. The mean thickness of endometrium, measured by Trans Vaginal ultrasonography was 6.25 ± 3.7 millimeter. In the biopsy derived specimens, the most finding pathological presentation was atrophy (48.9% and the Proliferative endometrium had the second prevalence (36.7%. Atrophy (44.4% and Proliferative endometrium (33.3% were the most prevalent finding in Hysteroscopy. There was a significant difference in endometrial thickness between groups of different pathological findings. A significant difference in endometrial thickness was also seen between groups with different Hysteroscopic finding. By grouping the data according to endometrial thickness, it became evident that endometrial thickness can predict the outcome of endometrial biopsy and Hysteroscopic finding efficiently. We used ROC curves to find the best grouping threshold for endometrial thickness to achieve the best sensitivity and specificity.Conclusion: Measuring the endometrial

Objective: To assess the efficacy of aspiration of small follicles(ASF) guided by trans-vaginal ultra- sound (TVS) in preventing moderate and severe ovarian hyperstimulation syndrome (OHSS) in women with polycystic ovaries syndrome (PCOS). Methods: ASF was undertaken by trans-vaginally during artificial cycles in 25 women with PCOS who had early signs of OHSS during the early period of the cycle according to the ovaries and follicles detected by TVS. Small follicles(≤ 12 mm in diameter) were aspirated at the early period of gonadotropin therapy according to the follicle testing, three or less excellent follicles were reserve. All the patients were followed up for symptoms and signs of OHSS. Results: None of the patients developed moderate or severe OHSS. Successful intrauterine pregnancy were found in 7 cases (28%). Conclusion: ASF after gonadotropin injections is of significance to prevent moderate and severe OHSS and obtain a higher pregnancy rate in susceptible patients with PCOS during the early period of the cycles. Time of ASF is the main factor to prevent OHSS. TVS may be an important tool in the detection of early period of follicles development. (authors)

Image-guided fine needle cytology with aspiration versus non-aspiration in retroperitoneal masses: is aspiration necessary?

Misra, Rajiv Kumar; Mitra, Shaila; Jain, Rishav Kumar; Vahikar, Shilpa; Bundela, Archana; Misra, Purak

2015-03-01

Although using fine needle cytology with aspiration (FNC-A) for establishing diagnoses in the retroperitoneal region has shown promise, there is scant literature supporting a role of non-aspiration cytology (FNC-NA) for this region. We assessed the accuracy and reliability of FNC-A and FNC-NA as tools for preoperative diagnosis of retroperitoneal masses and compared the results of both techniques with each other and with histopathology. Fifty-seven patients with retroperitoneal masses were subjected to FNC-A and FNC-NA. Smears were stained with May-Grunwald Giemsa and hematoxylin and eosin stain. An individual slide was objectively analysed using a point scoring system to enable comparison between FNC-A and FNC-NA. By FNC-A, 91.7% accuracy was obtained in cases of retroperitoneal lymph node lesions followed by renal masses (83.3%). The diagnostic accuracy of other sites by FNC-A varied from 75.0%-81.9%. By FNC-NA, 93.4% diagnostically accurate results were obtained in the kidney, followed by 75.0% in adrenal masses. The diagnostic accuracy of other sites by FNC-NA varied from 66.7%-72.8%. Although both techniques have their own advantages and disadvantages, FNC-NA may be a more efficient adjuvant method of sampling in retroperitoneal lesions.

Full Text Available Pure neuroendoscopic resection of intraventricular lesions through a burr hole is limited by the instrumentation that can be used with a working channel endoscope. We describe a safety and feasibility study of a variable aspiration tissue resector, for the resection of a variety of intraventricular lesions. Our initial experience using the variable aspiration tissue resector involved 16 patients with a variety of intraventricular tumors or cysts. Nine patients (56% presented with obstructive hydrocephalus. Patient ages ranged from 20 to 88 years (mean 44.2. All patients were operated on through a frontal burr hole, using a working channel endoscope. A total of 4 tumors were resected in a gross total fashion and the remaining intraventricular lesions were subtotally resected. Fifteen of 16 patients had relief of their preoperative symptoms. The 9 patients who presented with obstructive hydrocephalus had restoration of cerebrospinal fluid flow though one required a ventriculoperitoneal shunt. Three patients required repeat endoscopic resections. Use of a variable aspiration tissue resector provides the ability to resect a variety of intraventricular lesions in a safe, controlled manner through a working channel endoscope. Larger intraventricular tumors continue to pose a challenge for complete removal of intraventricular lesions.

This observational case series in 65 premenopausal women with abnormal uterine bleeding evaluated whether transvaginal ultrasound followed by saline infusion sonohysterography (SIS) prevented unnecessary hysteroscopy. Although SIS indicated that hysteroscopy was unnecessary in eight women, this benefit was offset by the invasive nature of the scan, the number of endometrial abnormalities falsely detected by SIS and the cost of the additional investigation. © 2016 The Royal Australian and New Zealand College of Obstetricians and Gynaecologists.

Medical doctor and engineer are highly esteemed STEM professions. This study investigates academic and motivational characteristics of a sample of high school students in Thailand who aspire to become medical doctors or engineers. We used logistic regression to compare maths performance, gender typicality, gender contentedness, and maths and physics self-concepts among students with aspirations for these two professions. We found that high levels of felt gender contentedness in men had positive association with aspirations for engineering irrespective of the levels of maths or physics self-concept. We found that high levels of felt gender contentedness combined with high levels of maths or physics self-concept in women had positive associations with aspirations to become a medical doctor. These findings are evidence that student views of self are associated with uneven gendered patterns in career aspirations and have implications for the potential for future participation.

The natural clinical progression of aspiration to eventual pulmonary compromise is not well understood. We hypothesized that dietary modification recommendations, Penetration-Aspiration Scale (PAS) score, and dysphagia etiology would be associated with changes in time to first pulmonary event and overall survival for patients with documented aspiration on radiologic testing. This study identified a cohort of patients with detectable unsensed penetration or aspiration on videofluoroscopic swallowing study (VFSS), and followed this cohort over time for development of pulmonary events and death. We then evaluated the association of aspiration severity and dietary modification recommendations on incidence of these endpoints. Retrospective chart review. A total of 2,616 VFSS exam reports were reviewed from our institution performed between January 1, 2009 and December 31, 2010. Aspiration or unsensed penetration (PAS of 5 or greater) was detected in 564 (21.5%) of these patients, who were then included in the study cohort. Medical records were reviewed retrospectively for development of pulmonary events (pneumonia, pneumonitis, or other life-threatening pulmonary illness) and all-cause mortality for up to 54 months after initial VFSS. Univariate Kaplan-Meier analysis and multivariate Cox regression were performed for time to first pulmonary event and survival predicted by recommended diet, PAS score, and dysphagia etiology. Dysphagia etiology was highly associated with increased development of pulmonary events for some patients, especially those with generalized nonspecific dysphagia due to deconditioning or frailty (hazard ratio [HZ] vs. stroke 2.95, 95% confidence interval [CI]: 1.53-5.69, P = .001) and esophageal dysphagia (HZ: 2.66, 95% CI: 1.17-6.02, P = .019). Dysphagia etiology was also associated with increased mortality for patients with generalized nonspecific dysphagia due to deconditioning or frailty (HZ: 3.32, 95% CI: 2.0-5.52, P dysphagia is associated

Wu, Nini; Hou, Yang; Wang, Qian; Yu, Chengfu

Parents' educational aspirations for youth play an important role in shaping youth's own educational aspirations; however, little is known about how and in what context parents may transmit their aspirations to youth effectively. This is of particular interest and import to be examined in Chinese families, given Chinese cultural emphasis on educational achievement and Chinese youth's outstanding academic performance internationally. By integrating several key theories of motivation and parental socialization (i.e., the expectancy-value model of academic achievement, the two-step model of value transmission, the contextual model of parenting, and the self-determination theory), the current study investigated simultaneously the mediating roles of parental involvement in youth's learning and youth's perceptions of parental aspirations, as well as the moderating role of parental warmth in the intergenerational transmission process of educational aspirations in Chinese families. A two-wave longitudinal study spanning about half a year was conducted among 323 Chinese seventh graders (54% female; M age  = 13.25 years) and one of their parents (median educational attainment = completion of high school, median monthly income = USD 766-1226). It was found that parental educational aspirations for youth were related positively both indirectly through parental involvement and directly to youth's perceptions of parental aspirations, which in turn were associated positively with youth's own educational aspirations about half a year later. It was also found that parental educational aspirations for youth and youth's own educational aspirations were associated positively with each other only when youth reported experiencing high levels of parental warmth, but unrelated when youth reported experiencing low levels of parental warmth, whereas such moderating effects of parental warmth were absent on the links from parental aspirations to youth's perceptions of parental

Manfro, R C; Gonçalves, L F; de Moura, L A

1998-01-01

To evaluate the utility of kidney aspiration cytology in the sequential monitorization of acute rejection in renal transplant patients. Thirty patients were submitted to 376 aspirations. The clinical diagnoses were independently established. The representativity of the samples reached 82.7%. The total corrected increment index and the number of immunoactivated cells were higher during acute rejection as compared to normal allograft function, acute tubular necrosis, and cyclosporine nephrotoxicity. The parameters to the diagnosis of acute rejection were sensitivity: 71.8%, specificity: 87.3%, positive predictive value: 50.9%, negative predictive value: 94.9% and accuracy 84.9%. The false positive results were mainly related to cytomegalovirus infection or to the administration of OKT3. In 10 out of 11 false negative results incipient immunoactivation was present alerting to the possibility of acute rejection. Kidney aspiration cytology is a useful tool for the sequential monitorization of acute rejection in renal transplant patients. The best results are reached when the results of aspiration cytology are analyzed with the clinical data.

Empowering change: The effects of energy provision on individual aspirations in slum communities

International Nuclear Information System (INIS)

Parikh, Priti; Chaturvedi, Sankalp; George, Gerard

2012-01-01

This paper discusses the role of energy provision in influencing the social aspirations of people living in slums. We examine factors that influence the shift in aspirations in five slum settlements using data from 500 interviews conducted in serviced and non-serviced slums from the state of Gujarat in India. The non-serviced slums did not have access to basic services namely water, sanitation, energy, roads, solid waste and rainwater management. We find empirical evidence which suggests that when basic infrastructure provisions are met, slum dwellers shift their focus from lower order aspirations to the higher order aspirations like health, education, housing and land ownership. We argue that energy provision enhances productivity and enables slum dwellers to shift their aspirations upwards. Furthermore, we test the effect of work days lost due to illness on the relationship between higher order aspirations and aspirations for energy provision. When provision of energy is low, higher work day loss dampens higher order aspirations. For policy makers, this study highlights the critical link between the infrastructure services preferred by slum dwellers and their social aspirations for growth. - Highlights: ► We examine the role of energy provision in influencing social aspirations of people living in slums. ► 500 household interviews conducted in five Indian slum settlements used for the analysis. ► Shift in slum dwellers aspirations from non-serviced to serviced conditions examined using Herzberg’s theory. ► Link between energy provision and higher order aspirations established through a regression model. ► Policy recommendation is to encourage investment in infrastructure services as a driver for development.

Marcus-Braun, Naama; von Theobald, Peter

2010-04-01

The objective of the study was to reveal the way we treat vaginal mesh complications in a trained referral center. This is a retrospective review of all patients who underwent surgical removal of transvaginal mesh for mesh-related complications during a 5-year period. Eighty-three patients underwent 104 operations including 61 complete mesh removal, 14 partial excision, 15 section of sub-urethral sling, and five laparoscopies. Main indications were erosion, infection, granuloma, incomplete voiding, and pain. Fifty-eight removals occurred more than 2 years after the primary mesh placement. Mean operation time was 21 min, and there were two intraoperative and ten minor postoperative complications. Stress urinary incontinence (SUI) recurred in 38% and cystocele in 19% of patients. In a trained center, mesh removal was found to be a quick and safe procedure. Mesh-related complications may frequently occur more than 2 years after the primary operation. Recurrence was mostly associated with SUI and less with genital prolapse.

Full text: Children with cerebral palsy (CP) may have abnormal respiratory function because of aspiration pneumonitis, chest deformity, upper airways obstruction or central respiratory control abnormalities. The diagnosis of aspiration has long confounded clinicians and is often made indirectly after exclusion of other causes of respiratory disease in susceptible individuals.

Full text: Children with cerebral palsy (CP) may have abnormal respiratory function because of aspiration pneumonitis, chest deformity, upper airways obstruction or central respiratory control abnormalities. The diagnosis of aspiration has long confounded clinicians and is often made indirectly after exclusion of other causes of respiratory disease in susceptible individuals.

An Aspirational Community Theory of the Firm

DEFF Research Database (Denmark)

Li, Xin

propose an aspirational community theory of the firm (ACT) as a candidate theory by conceptualizing the firm as an aspirational community, the core of which is a group of like-minded people sharing similar or same aspiration/vision. To explain the existence of the firm, we make a distinction between......All of the three major theories of the firm, i.e., the transaction cost theory, knowledge-based theory and the entrepreneurship theory, offer some insightful analyses of the nature of the firm. However, they all have limitations and weaknesses in answering the fundamental question of the existence...... of the firm. In addition, they are all partial due to their particular focus on the multifaceted phenomenon of the firm. We argue that it is necessary and sufficient to develop a comprehensive yet integrative theory of the firm that combines the three competing yet complementary logics. Toward this end, we...

The development of lipid aspiration pneumonia after chronic nasopharyngeal installation of mineral oil was first described in 1925 by Laughlin. Since that time this entity has been well recognized and numerous substances have been identified or implicated as the aspirated material. The classic radiographic appearance of severe chronic lipid aspiration pneumonia has been described as consisting of intense perihilar infiltrates. However, the radiographic findings are more often non-specific and usually consist of varying degrees of diffuse interstitial infiltrates that tend to be more prominent in the perihilar regions and the right lung. We are reporting a case of biopsy-proven lipid aspiration pneumonia in an infant with known gastro-esophageal reflux (GER) who had medium-chain triglyceride oil administered via nasogastric tube. Serial roentgenograms demonstrated a changing pulmonary pattern from diffuse bilateral interstitial infiltrates initially to a diffuse alveolar pattern at the time of the lung biopsy. Modern medicine has developed new methods for providing nourishment to sick newborns and infants to improve their nutritional status and help them to grow. One such method involves the administration of medium-chain triglycerides (MCT oil) into the GI tract via a nasogastric or nasoenteral tube. The purpose of this report is to describe a significant complication of this method of providing nutrition to an infant with gastroesophageal reflux (GER) and the diagnostic dilemma it presented.

The Path Taken: Consequences of Attaining Intrinsic and Extrinsic Aspirations in Post-College Life.

Science.gov (United States)

Niemiec, Christopher P; Ryan, Richard M; Deci, Edward L

2009-06-01

Life goals, or aspirations, organize and direct behavior over extended periods of time. The present study, guided by self-determination theory, examined the consequences of pursuing and attaining aspirations over a one-year period in a post-college sample. Results indicated that placing importance on either intrinsic or extrinsic aspirations related positively to attainment of those goals. Yet, whereas attainment of intrinsic aspirations related positively to psychological health, attainment of extrinsic aspirations did not; indeed, attainment of extrinsic aspirations related positively to indicators of ill-being. Also as predicted, the association between change in attainment of intrinsic aspirations and change in psychological health was mediated by change in the satisfaction of the basic psychological needs for autonomy, competence, and relatedness. Discussion focuses on the idea that not all goal attainment is beneficial; rather, attainment of aspirations with different contents relates differentially to psychological health.

Seawater drowning-induced acute lung injury (ALI) is a serious clinical condition characterized by increased alveolar-capillary permeability, excessive inflammatory responses, and refractory hypoxemia. However, current therapeutic options are largely supportive; thus, it is of great interest to search for alternative agents to treat seawater aspiration-induced ALI. Erythropoietin (EPO) is a multifunctional agent with antiinflammatory, antioxidative, and antiapoptotic properties. However, the effects of EPO on seawater aspiration-induced ALI remain unclear. In the present study, male rats were randomly assigned to the naive group, normal saline group, seawater group, or seawater + EPO group. EPO was administered intraperitoneally at 48 and 24 h before seawater aspiration. Arterial blood gas analysis was performed with a gas analyzer at baseline, 30 min, 1 h, 4 h, and 24 h after seawater aspiration, respectively. Histological scores, computed tomography scan, nuclear factor kappa B p65, inducible nitric oxide synthase, caspase-3, tumor necrosis factor-alpha, interleukin (IL)-1β, IL-6, IL-10, wet-to-dry weight ratio, myeloperoxidase activity, malondialdehyde, and superoxide dismutase in the lung were determined 30 min after seawater aspiration. Our results showed that EPO pretreatment alleviated seawater aspiration-induced ALI, as indicated by increased arterial partial oxygen tension and decreased lung histological scores. Furthermore, EPO pretreatment attenuated seawater aspiration-induced increase in the expressions of pulmonary nuclear factor kappa B p65, inducible nitric oxide synthase, caspase-3, tumor necrosis factor-alpha, IL-1β, myeloperoxidase activity, and malondialdehyde when compared with the seawater group. Collectively, our study suggested that EPO pretreatment attenuates seawater aspiration-induced ALI by down-regulation of pulmonary pro-inflammatory cytokines, oxidative stress, and apoptosis.

To determine the role of fine needle aspiration cytology in the diagnosis of extramedullary plasmacytoma. The study group consisted of 13 patients with palpable masses at various sites. The tumors were aspirated for cytologic study. The smears revealed groups of mature and immature plasma cells at various stages of maturation. Mature plasma cells showed an eccentric nucleus and abundant, deep, basophilic cytoplasm with a paranuclear halo. Plasmablasts (immature plasma cells) showed a prominent, eccentric nucleus with single, large nucleolus and abundant, deep, basophilic cytoplasm with no paranuclear halo. Binucleate and multinucleate forms were also seen quite often. The tumors were excised, and the histologic sections confirmed the cytologic diagnosis. All the patients received radiotherapy. One patient (18 years old) developed recurrence and died due to extensive infiltration into the maxilla and mandible. Two patients (57 and 62 years) developed multiple myeloma one to two years after the excision of tumors, and both died two to three months later. The remaining 10 patients were alive and well at this writing. The smears from all 13 patients were diagnosed as extramedullary plasmacytomas by fine needle aspiration cytology.

Transvaginal coloanal anastomosis after rectal resection for the treatment of a rectovaginal fistula induced by radiation.

Science.gov (United States)

Brezean, I

2014-01-01

Although decreasing in number, radiation induced rectovaginal fistulas are caused by some radiation injuries and chronic ischemic lesions. Most of the experienced authors recommend anterior rectal resection with coloanal anastomosis accessed through the abdominal-perineum area for high fistula. We present a patient with a fistula that developed 23 years after hysterectomy and radiotherapy. In this case we performed an abdominal-transvaginal rectal resection with transverse coloplastypouch, coloanal anastomosis and protection ileostomy three months after a terminal sigmoidostomy. The dissection of the distal rectum by posteriour colpotomy and coloanal transvaginalan astomosis is a technical variant that may prove advantage ous compared to the procedures featured in the literature as solutions by rectal resection for rectovaginal fistula.

Aspiration of human neutrophils: effects of shear thinning and cortical dissipation.

Science.gov (United States)

Drury, J L; Dembo, M

2001-12-01

It is generally accepted that the human neutrophil can be mechanically represented as a droplet of polymeric fluid enclosed by some sort of thin slippery viscoelastic cortex. Many questions remain however about the detailed rheology and chemistry of the interior fluid and the cortex. To address these quantitative issues, we have used a finite element method to simulate the dynamics of neutrophils during micropipet aspiration using various plausible assumptions. The results were then systematically compared with aspiration experiments conducted at eight different combinations of pipet size and pressure. Models in which the cytoplasm was represented by a simple Newtonian fluid (i.e., models without shear thinning) were grossly incapable of accounting for the effects of pressure on the general time scale of neutrophil aspiration. Likewise, models in which the cortex was purely elastic (i.e., models without surface viscosity) were unable to explain the effects of pipet size on the general aspiration rate. Such models also failed to explain the rapid acceleration of the aspiration rate during the final phase of aspiration nor could they account for the geometry of the neutrophil during various phases of aspiration. Thus, our results indicate that a minimal mechanical model of the neutrophil needs to incorporate both shear thinning and surface viscosity to remain valid over a reasonable range of conditions. At low shear rates, the surface dilatation viscosity of the neutrophil was found to be on the order of 100 poise-cm, whereas the viscosity of the interior cytoplasm was on the order of 1000 poise. Both the surface viscosity and the interior viscosity seem to decrease in a similar fashion when the shear rate exceeds approximately 0.05 s(-1). Unfortunately, even models with both surface viscosity and shear thinning studied are still not sufficient to fully explain all the features of neutrophil aspiration. In particular, the very high rate of aspiration during the

2009-08-01

We report the case of a 38-year-old neurologically impaired woman with continuous urinary incontinence as a result of a chronic indwelling catheter for neurogenic bladder. Long-term catheter resulted in dilatation of urethra and pressure necrosis of urethra, with subsequent incontinence despite the catheter. She also had a stage 3 uterovaginal prolapse. She underwent cystoscopy, closure of urethra and bladder neck by transvaginal route (Feneley procedure), insertion of a suprapubic catheter, sacrospinous fixation and posterior colporrhaphy with prolene mesh (Apogee). Vaginal hysterectomy was declined by the patient and her family. She remained dry at follow-up visit and is happy with the outcome.

Laparoscopic mesh explantation and drainage of sacral abscess remote from transvaginal excision of exposed sacral colpopexy mesh.

Roth, Ted M; Reight, Ian

2012-07-01

Sacral colpopexy may be complicated by mesh exposure, and the surgical treatment of mesh exposure typically results in minor postoperative morbidity and few delayed complications. A 75-year-old woman presented 7 years after a laparoscopic sacral colpopexy, with Mersilene mesh, with an apical mesh exposure. She underwent an uncomplicated transvaginal excision and was asymptomatic until 8 months later when she presented with vaginal drainage and a sacral abscess. This was successfully treated with laparoscopic enterolysis, drainage of the abscess, and explantation of the remaining mesh. Incomplete excision of exposed colpopexy mesh can lead to ascending infection and sacral abscess. Laparoscopic drainage and mesh removal may be considered in these patients.

Repetition of the onset of aspiration pneumonia in aged patients is common and causes chronic inflammation. The inflammation induces proinflammatory cytokine production and atrophy in the muscles. The proinflammatory cytokines induce muscle proteolysis by activating calpains and caspase-3, followed by further degradation by the ubiquitin-proteasome system. Autophagy is another pathway of muscle atrophy. However, little is known about the relationship between aspiration pneumonia and muscle. For swallowing muscles, it is not clear whether they produce cytokines. The main objective of this study was to determine whether aspiration pneumonia induces muscle atrophy in the respiratory (the diaphragm), skeletal (the tibialis anterior, TA), and swallowing (the tongue) systems, and their possible mechanisms. We employed a mouse aspiration pneumonia model and computed tomography (CT) scans of aged pneumonia patients. To induce aspiration pneumonia, mice were inoculated with low dose pepsin and lipopolysaccharide solution intra-nasally 5 days a week. The diaphragm, TA, and tongue were isolated, and total RNA, proteins, and frozen sections were stored. Quantitative real-time polymerase chain reaction determined the expression levels of proinflammatory cytokines, muscle E3 ubiquitin ligases, and autophagy related genes. Western blot analysis determined the activation of the muscle proteolysis pathway. Frozen sections determined the presence of muscle atrophy. CT scans were used to evaluate the muscle atrophy in aged aspiration pneumonia patients. The aspiration challenge enhanced the expression levels of proinflammatory cytokines in the diaphragm, TA, and tongue. Among muscle proteolysis pathways, the aspiration challenge activated caspase-3 in all the three muscles examined, whereas calpains were activated in the diaphragm and the TA but not in the tongue. Activation of the ubiquitin-proteasome system was detected in all the three muscles examined. The aspiration challenge

Neonates undergoing heart surgery for CHD are at risk for postoperative gastrointestinal complications and aspiration events. There are limited data regarding the prevalence of aspiration after neonatal cardiothoracic surgery; thus, the effects of aspiration events on this patient population are not well understood. This retrospective chart review examined the prevalence and effects of aspiration among neonates who had undergone cardiac surgery at the time of their discharge. Introduction This study examined the prevalence of aspiration among neonates who had undergone cardiac surgery. Demographic data regarding these patients were analysed in order to determine risk factors for postoperative aspiration. Post-discharge feeding routes and therapeutic interventions were extracted to examine the time spent using alternate feeding routes because of aspiration risk or poor caloric intake. Modified barium swallow study results were used to evaluate the effectiveness of the test as a diagnostic tool. Materials and methods A retrospective study was undertaken of neonates who had undergone heart surgery from July, 2013 to January, 2014. Data describing patient demographics, feeding methods, and follow-up visits were recorded and compared using a χ2 test for goodness of fit and a Kaplan-Meier graph. The patient population included 62 infants - 36 of whom were male, and 10 who were born with single-ventricle circulation. The median age at surgery was 6 days (interquartile range=4 to 10 days). Modified barium swallow study results showed that 46% of patients (n=29) aspirated or were at risk for aspiration, as indicated by laryngeal penetration. In addition, 48% (n=10) of subjects with a negative barium swallow or no swallow study demonstrated clinical aspiration events. Tube feedings were required by 66% (n=41) of the participants. The median time spent on tube feeds, whether in combination with oral feeds or exclusive use of a nasogastric or gastric tube, was 54 days; 44% (n

Turban pin aspiration syndrome is a new clinical entity afflicting young Islamic girls wearing a turban.The goal of this study was to present our experience in diagnosis and treatment of this new entity, define its clinical and epidemiologic features, and shed a new light on the role of fashion in the increased incidence. A retrospective study in a tertiary university hospital. Review of clinical parameters and epidemiologic features of 26 patients diagnosed with turban pin aspiration syndrome admitted to the Hadassah-Hebrew University Hospitals in Jerusalem from 1990 to 2010. All patients were Muslim females with an average age of 16 years. In all cases, the history was positive for accidental aspiration. Most of the pins were located in the trachea (42%). In 20 cases, the pins were extracted by rigid bronchoscopy without major complications. Fluoroscopy-assisted rigid bronchoscopy was used successfully in three cases. In one case, the object was self-ejected by coughing before the bronchoscopy, and two patients were referred to the chest unit for thoracotomy. Clinicians should be aware of this distinct form of foreign body aspiration, its method of diagnosis, and extraction techniques. A cultural investigation showed a difference in the turban-fastening technique of young girls as compared with their mothers. Removal by rigid bronchoscopy is a safe method with a high success rate and should be considered as the preferred extraction method of choice.

Based on Globocan data in 2012, it is estimated that about 14,495 Indonesians suffer from lymphoma, both Hodgkin’s lymphoma, and non-Hodgkin’s lymphoma. Some areas of specialization still doubt the accuracy of cytology diagnosis of fine needle aspiration biopsy.This study is a diagnostic test with a cross sectional analytic design to see how the cytology diagnostic accuracy of fine needle aspiration aspirate in lymphoma. It was in Department of Anatomical Pathology Faculty of Medicine USU, Haji Adam Malik Hospital, Dr.Pirngadi hospital, or private clinic in Medan. Peripheral cytology technique biopsy of fine needle aspiration on lymph node subsequently stained with Giemsa, when the cytology of lymphoma is obtained and confirmed by histopathologic examination. Cytology and histopathologic examination will be tested by Diagnostic Test and assessed for its sensitivity and specificity. The diagnostic of lymphoma cytology provides 93.33% sensitivity and 92.31% specificity when confirmed by histopathological examination. Positive predictive value and negative predictive value of 96.55% and 85.71% respectively. In conclusion, the cytology of fine needle aspiration biopsy is accurate enough to be used as a diagnostic tool, so it is advisable to establish a lymphoma diagnosis to perform a needle aspiration biopsy examination.

Coevolution of aspirations and cooperation in spatial prisoner's dilemma game

Chen, Wei; Wu, Te; Li, Zhiwu; Wang, Long

2015-01-01

Suboptimal outcomes are often more acceptable than the best ones when the latter are hard or even impossible to find. In order to describe the emergence of cooperation when suboptimal alternatives prevail, an evolutionary game model is established by considering the effects of aspirations. A win-stay-lose-shift like rule for strategy updating is proposed. The rule prescribes that if the payoff of the current strategy is greater than the aspiration, the strategy remains, otherwise the strategy changes. Aspiration updating allows for individuals to adjust their expected payoff levels. It is shown that suboptimal alternatives can promote the emergence and persistence of cooperation over a wide range of the temptation to defect. Furthermore, a nontrivial phenomenon is found that cooperators prevail as the temptation increases when it is small. The aspirations are stabilized at an intermediate level which can most facilitate cooperation. The obtained results also show that the average level of aspirations decreases as the temptation increases. Furthermore, the variance of aspiration levels is minimized for an intermediate level of temptation. (paper)

Radiographic-guided fine-needle aspiration of nonpalpable breast lesions

1989-01-01

The authors have performed radiographically guided fine-needle aspirations (FNA) on 215 nonpalpable mammographically detected breast lesions, using a coordinate grid localization system. Aspirates were classified into five cytologic groups. With the most stringent cytologic criteria, the sensitivity was 98% and the specificity 95% for the detection of carcinoma. However, according to these strict cytologic criteria, only 46% of aspirates contained representative material. Forty-two of 74 lesions undergoing biopsy proved malignant. Sixteen percent of patients did not compete adequate mammographic follow-up. High sensitivity and specificity can be achieved with radiographically guided FNA. However, management decisions ultimately require integration of mammographic findings with cytologic results. Close cooperation between mammographer, surgeon, cytopathologist, and patients is mandatory for successful operation

The most important method for evaluating the pathogenesis of male infertility is open testicular biopsy. Herein the authors describe a method of aspiration biopsy of testis for histologic examination. Sexually mature dogs and rats treated with chemotherapeutic agents and ionizing radiation were followed with periodic testicular aspiration biopsy during and after treatment. The histologic findings from the aspiration biopsy compare with the results of routine histologic examination in assessing spermatogenetic activity and delineating pathologic changes. The puncture in the experimental animals was performed under general anesthesia. In human patients testicular biopsy could be done under local anesthesia in an outpatient clinic. The procedure would be less painful, minimally invasive, and more cost-effective

The aim of our study was to analyze the reliability of postmortem computed tomography (PMCT) versus autopsy in detecting signs of blood aspiration in a distinct group of patients following deadly head, mouth or floor of mouth gunshot injuries. In this study, in 41 cases PMCT was compared to autopsy reports, the gold standard of postmortem exams, regarding detection of blood aspiration. PMCT was evaluated for the presence and level of typical signs of blood aspiration in the major airways and lung using a semi-quantitative scale ranging from level 0 (no aspiration) to 3 (significant aspiration) also taking density values of the described potential aspiratory changes into account. Overall, in 29 (70.7%) of 41 enrolled cases PMCT and autopsy revealed the same level of aspiration. A difference of one level between PMCT and autopsy resulted for 5 (12.2%) of the remaining 12 cases. More than one level difference between both methods resulted for 7 cases (17.2%). Autopsy described no signs of aspiration in 10 cases, compared to 31 cases with reported blood aspiration. In contrast, PMCT revealed no signs of blood aspiration in 15 cases whereas 26 cases were rated as positive for signs of aspiration in the major airways. In 18 of these 26 cases considered positive for blood aspiration by autopsy and PMCT, clear signs of aspiration signs were also described bilaterally by both methods. The presented study provides evidence for the assumption that PMCT seems to be helpful in the detection of blood aspiration in cases of deadly head gunshots. In conclusion, it seems reasonable to suggest performing PMCT additionally to traditional postmortem exams in cases of suspected aspiration to rule out false-negative cases and to possibly allow for a more detailed and rather evidence based examination reconnoitering the cause of death. However, the adequate use of PMCT in this context needs further evaluation and the definition of an objective scale for aspiration detection on PMCT needs

Perioperative pulmonary aspiration is infrequent and low risk in pediatric anesthetic practice.

Recent studies have reported perioperative pulmonary aspiration in pediatric practice to be an uncommon problem associated with low morbidity and mortality. This paper examines the recent publications in both the adult and pediatric literature and looks at some of the potential risk factors involved, both patient and anesthetic, in the development of aspiration of gastric contents. We also look at the risk of severe morbidity following pulmonary aspiration and speculate on possible reasons behind the assertion that pulmonary aspiration in pediatric anesthetic practice is rare and a low-risk event. © 2014 John Wiley & Sons Ltd.

The Consequences of the National Math and Science Performance Environment for Gender Differences in STEM Aspiration

Directory of Open Access Journals (Sweden)

Allison Mann

2016-07-01

Full Text Available Using the lens of expectation states theory, which we formalize in Bayesian terms, this article examines the influences of national performance and self-assessment contexts on gender differences in the rate of aspiring to science, technology, engineering, and mathematics (STEM occupations. We demonstrate that girls hold themselves to a higher performance standard than do boys before forming STEM orientations, and this gender "standards gap" grows with the strength of a country’s performance environment. We also demonstrate that a repeatedly observed paradox in this literature—namely, that the STEM gender gap increases with a more strongly gender-egalitarian national culture—vanishes when the national performance culture is taken into account. Whereas other research has proposed theories to explain the apparent paradox as an empirical reality, we demonstrate that the empirical relationship is as expected; net of the performance environment, countries with a more gender-egalitarian culture have a smaller gender gap in STEM orientations. We also find, consistent with our theory, that the proportion of high-performing girls among STEM aspirants grows with the strength of the national performance environment even as the overall gender gap in STEM orientations grows because of offsetting behavior by students at the lower end of the performance distribution.

Full Text Available Thyroid nodules are common. Malignancy was reported in only 5-15% of cases. Fine needle aspiration under US guidance (USG-FNA proved to be accurate for the detection of thyroid cancer. This is a retrospective review of 400 radiology and cytology USG-FNA reports, randomly selected among those done at the Radiology Department at a tertiary care center in Beirut during the last five years. The specimen was inadequate in 60 (12% of cases but FNA was repeated in 10 cases only. The final diagnosis was benign in 76.7% of cases, mostly in women. 35% of the malignant and 19% of the benign nodules were hypoechoic, p=0.03. No significant correlation was observed between malignancy and other ultrasonic characteristics. Hypoechogenecity was also more common in nodules with inadequate specimen (40% versus 21.4%, p=0.01. Age, gender, location and size of the nodule did not differ between groups of adequate and inadequate specimen. In conclusion, 3 out of 4 thyroid nodules referred for USG-FNA are benign, mostly in women. Inadequate specimen was observed in 12% of cases. Hypoechogenecity but not other ultrasonic characteristics was associated with malignancy and with test failure.   Key words: Thyroid nodule, fine needle aspirate, ultrasound guidance, thyroid cancer, inadequate.

A 30-year-old female presented with a three-month history of a multilocular cystic lesion over the lumbosacral spine. Fine-needle aspiration biopsy (FNA) of the lesion was performed at an outside institution, and a cytologic diagnosis, suspicious for chordoma, was rendered. The patient presented for surgical consultation at our institution. Repeat FNA demonstrated an unusual fat-like material. Upon further inquiry, the patient provided a recent history of gluteal contour improvement with fibroadipose tissue implants. A diagnosis of myospherulosis was made with a concurrent surgical pathology correlation. No evidence of chordoma was identified. To date, this is the first reported case of acquired myospherulosis in the context of gluteal contour enhancement and represents an important diagnostic pitfall to consider on cytology preparations. © 2017 Wiley Periodicals, Inc.

1996-01-01

Sixty-eight CT-guided aspirative biopsies of hepatic nodules were performed at A.C. Camargo Hospital, Sao Paulo, Brazil, from 1992 to 1995. The cases were distributed as follow: 44(64.7%) with a positive diagnosis for neoplastic cells, 6(8.8%) with a negative diagnosis, and 14 (20.5%) with insufficient material. Of the positive cases (primary neoplasias and metastases), the cytological diagnosis was achieved in 39 cases. There were 36 cases of carcinoma (7 hepato carcinomas, 18 adenocarcinomas, 1 small cell carcinoma and 10 cases of unspecified differentiation), 2 cases of melanoma and 1 case of melanoma and 1 case of sarcoma. The correlation with histopathological exams showed no false positive cases and concordance between cytological and histopathological diagnosis. The results demonstrate that CT-guided aspirative biopsy of hepatic nodules permits a rapid diagnosis of neoplastic lesions, especially for the evaluation of metastases. (author)

Lee, Jin Seong; Gong, Gyung Yub; Lim, Tae Hwan

1998-01-01

The purpose of this study was to describe the thin-section computed tomography (CT) findings and histopathologic findings of squalene aspiration pneumonia. Thin-section CT scans were obtained from nine patients with proven exogenous lipoid pneumonia resulting from aspiration of squalene (derived from shark liver oil). The condition was diagnosed by biopsy (n=3), bronchoalveolar lavage(n=4), or sputum cytology and clinical history (n=2) of squalene use was confirmed in all patients. Specimens of transbronchial lung biopsy were also reviewed and compared with thin-section CT findings. On the basis of these results, we concluded that squalene aspiration pneumonia can be reliably diagnosed by thin-section CT findings particularly when the appropriate history is known.

Ko, Eun Sook; Shin, Jung Hee; Sung, Jin Yong

2014-01-01

We aimed to evaluate the efficacy and safety of vigorous saline injection for viscous cystic thyroid nodules. Eighteen patients who underwent ultrasound-guided aspiration for viscous cystic thyroid nodules using a saline injection were included in our study. After failing to aspirate the cyst by the usual method, we vigorously injected saline into the cyst in multiple directions to break up and liquefy the viscous cystic contents to enable aspiration. The initial and the residual volume of the nodule were calculated, and the volume reduction rate and the time taken to perform the aspiration were recorded. The mean volume of the cystic nodules before aspiration was 11.0 mL (range, 1.2 to 26.0 mL), while the postaspiration volume was 4.2 mL (range, 0.2 to 14.5 mL). The mean aspirated volume was 63.7% of the initial volume. The mean procedure time was 12.4 minutes (range, 5 to 26 minutes). There were no significant complications related to the procedure. A vigorous saline injection followed by aspiration can be a useful method to aspirate viscous cystic thyroid nodules as a prestep for further intervention or simple management.

Air Bag Momentum Force Including Aspiration

Directory of Open Access Journals (Sweden)

Guy Nusholtz

1995-01-01

Full Text Available A gas-jet momentum force drives the air bag into position during a crash. The magnitude of this force can change as a result of aspiration. To determine the potential magnitude of the effect on the momentum force and mass flow rate in an aspirated system, a series of experiments and simulations of those experiments was conducted. The simulation consists of a two-dimensional unsteady isentropic CFD model with special “infinite boundaries”. One of the difficulties in simulating the gas-jet behavior is determining the mass flow rate. To improve the reliability of the mass flow rate input to the simulation, a sampling procedure involving multiple tests was used, and an average of the tests was adopted.

Results: Twenty-three (53.4% of the patients obtained complete resolution (no focal collection after one aspiration; 9 (21% required two aspirations and 8 (18.6% required more than two aspirations for the cure (residual collection. In 3 (7% of the patients, the treatment failed, where symptoms had not resolved after 3 days, with further pus collection despite aspiration and antibiotics, where surgical drainage was required. Conclusions: Percutaneous needle drainage of breast abscesses after preliminary breast US is feasible as a primary and definitive treatment for breast abscesses, if complete or near complete drainage is achieved.

Jeffery, Stephen T; Nieuwoudt, Andri

2012-10-01

The aims of this study were to assess the anatomical, sexual and functional outcomes of women undergoing surgical intervention for complications of the trocar-guided transvaginal mesh (TVM) procedure. This was a retrospective analysis of a clinical database of women who had developed a complication following a TVM procedure. This included dyspareunia, mesh erosion, urinary symptoms, mesh contraction and prolapse recurrence. Pre- and post-operatively, we assessed the women for prolapse, stress incontinence, urgency, defecatory difficulty, digitation, pain, dyspareunia and apareunia. We also recorded the Pelvic Organ Prolapse Quantification (POP-Q) score. The TVM was removed and a Biodesign graft was used in the majority of cases to prevent further prolapse. Follow-up was at 6 weeks, 6 months, 1 and 2 years. In our cohort of 21 women, 18 required surgery for pain and/or dyspareunia; 20 women had reached the 6-week follow-up at the time of analysis. At 6 weeks, two women still had pain and required a second intervention. Fifteen women had reached a 6-month follow-up and only one woman had persistent pain requiring repeat surgery. Of the 15 women, 7 were sexually active and in 6 cases the dyspareunia had resolved completely with 1 woman retaining an element of pain at intercourse. Six women had been seen at 12 months and all four of the sexually active women had no dyspareunia. There were no symptoms relating to prolapse in any of the women at 6 weeks, 6, 12 or 24 months. We report satisfactory outcomes following removal of a complicated TVM kit.

Foreign body (FB) aspiration can be a life-threatening event. Although more common in children, FB aspiration can occur at any age. Symptoms related to FB aspiration range from coughing and shortness of breath to asphyxiation. Chest imaging can be nonspecific and infrequently identifies an FB. Herein, we describe a case of a 54-year-old male patient who aspirated an FB and experienced respiratory arrest. He failed to improve with conservative measures and required emergent bronchoscopy. He was found to have an FB in his proximal left mainstem bronchus that could not be removed using standard bronchoscopy and he was referred to our center for definitive care. We used a cryotherapy probe to remove the FB. We propose that cryotherapy is a useful tool to remove FBs that are soft and amenable to freezing.

Bio rapid prototyping by extruding/aspirating/refilling thermoreversible hydrogel

International Nuclear Information System (INIS)

Iwami, K; Noda, T; Ishida, K; Umeda, N; Morishima, K; Nakamura, M

2010-01-01

This paper reports a method for rapid prototyping of cell tissues, which is based on a system that extrudes, aspirates and refills a mixture of cells and thermoreversible hydrogel as a scaffold. In the extruding mode, a cell-mixed scaffold solution in the sol state is extruded from a cooled micronozzle into a temperature-controlled substrate, which keeps the scaffold in the gel state. In the aspiration mode, the opposite process is performed by Bernoulli suction. In the refilling mode, the solution is extruded into a groove created in the aspiration mode. The minimum width of extruded hydrogel pattern is 114 ± 15 μm by employing a nozzle of diameter 100 μm, and that of aspirated groove was 355 ± 10 μm using a 500 μm-diameter nozzle. Gum arabic is mixed with the scaffold solution to avoid peeling-off of the gel pattern from the substrate. Patterning of Sf-9 cell tissue is demonstrated, and the stability of the patterned cell is investigated. This system offers a procedure for rapid prototyping and local modification of cell scaffolds for tissue engineering.

Full Text Available Context: Dysplastic changes are well documented in myelodysplastic syndromes (MDS. However, they are also observed in non-MDS hematological conditions. Aims: To evaluate the megakaryocytic alterations in the bone marrow aspirations in cases of non-MDS related thrombocytopenia. Setting and Design: A prospective study of 144 bone marrow aspirates was conducted in the department of pathology, Kasturba Medical College, Mangalore. The aspirates were studied to assess the number and morphology of the megakaryocytes in non-MDS related thrombocytopenia and evaluate their significance when compared to changes in MDS. Materials and Methods: The bone marrow aspiration smears were stained with Leishman stain and examined under light microscope. Statistical Analysis Used: Fisher′s exact test. A P value less than 0.05 was considered significant. Sensitivity and specificity was calculated for those features which were significant in the relevant hematological disorders. Results: The sensitivity of immature megakaryocytes, dysplastic forms and micromegakaryocytes in cases of immune thrombocytopenic purpura was 100%, 89% and 42% respectively. The specificity of emperipolesis was 74%. In cases of infection-associated thrombocytopenia, immature megakaryocytes had a sensitivity of 100% and cytoplasmic vacuolization were 86% specific. The sensitivity of the dysplastic forms in megaloblastic anemia was 75%. However, no platelet budding was observed. The presence of micromegakaryocyte had a specificity of 83% in MDS, and was statistically significant when compared to cases of non-MDS conditions (P< 0.05. Conclusions: Careful understanding of the morphological changes of megakaryocytes in bone marrow aspirates can improve the diagnostic accuracy for a wide range of hematological disorders thereby enabling proper therapeutic interventions.

To assess the penetration of media-based information on transvaginal mesh (TVM) in our patient population and to determine whether exposure affects patient opinion. Since the 2011 Federal Drug Administration communication on TVM, many advertisements from legal practices have been directed toward patients. An 18-item survey was administered to female patients at 2 sites from August 2012 to April 2013. Patients presenting with new diagnoses of pelvic organ prolapse or stress urinary incontinence or patients who reported prior mesh surgery were excluded. Ninety-nine questionnaires were completed. Sixty-six of the patients (67%) were aware of TVM; and of these, 38 (58%) cited advertisements as the initial source of information. Only 12% were aware of the Food and Drug Administration's communication. Regarding opinion of TVM, 9% chose "it is a safe product," 9% "safety depends on factors related to patient," 4.5% "not a safe product," 1.5% "safety depends on the doctor," 68% "I don't know," and 4.5% marked 2 selections. Only 12% indicated knowing the difference in the use of TVM for pelvic organ prolapse vs stress urinary incontinence. When asked what influenced their opinion of TVM the most; responses were as follows: advertisement (33.3%), medical professional (22.7%), friends or family who underwent TVM procedure (12.1%), media article (6.1%), and "not sure" (25.8%). Advertisements of TVM lawsuits had a high penetration into our patient population but did not produce an overtly negative response in our sample. Clinicians should be aware of the impact of these advertisements on patient opinion and counsel patients accordingly with unbiased and scientifically accurate information.

To measure the proportion of women with transvaginal prolapse mesh complications and their association with surgeon volume. We conducted a retrospective, population-based cohort study of all women who underwent a mesh-based prolapse procedure using administrative data (hospital procedure and physician billing records) between 2002 and 2013 in Ontario, Canada. The primary outcome was surgical revision of the mesh. Primary exposure was surgeon volume: high (greater than the 75th percentile, requiring a median of five [interquartile range 5-6] procedures per year) and very high (greater than the 90th percentile, requiring a median of 13 [interquartile range 11-14] procedures per year) volume mesh implanters were identified each year. Primary analysis was an adjusted Cox proportional hazards model. A total of 5,488 women underwent mesh implantation by 1 of 368 unique surgeons. Median follow-up time was 5.4 (interquartile range 3.0-8.0) years. We found that 218 women (4.0%) underwent mesh reoperation a median of 1.17 (interquartile range 0.58-2.90) years after implantation. The hazard of reoperation for complications was only lower for patients of very high-volume surgeons (3.0% [145/3,001] compared with 4.8% [73/2,447], adjusted hazards ratio 0.59, 95% confidence interval 0.40-0.86). In multivariable modeling, younger age, concomitant hysterectomy, blood transfusion, and increased medical comorbidity were all associated with vaginal mesh reoperation. Approximately 5% of women who underwent mesh-based prolapse surgery required reoperation for a mesh complication within 10 years. The risk of reoperation was lowest for surgeons performing 14 or more procedures per year.

Aspiration-based coevolution of link weight promotes cooperation in the spatial prisoner's dilemma game

Science.gov (United States)

Shen, Chen; Chu, Chen; Shi, Lei; Perc, Matjaž; Wang, Zhen

2018-05-01

In this article, we propose an aspiration-based coevolution of link weight, and explore how this set-up affects the evolution of cooperation in the spatial prisoner's dilemma game. In particular, an individual will increase the weight of its link to its neighbours only if the payoff received via this interaction exceeds a pre-defined aspiration. Conversely, if the received payoff is below this aspiration, the link weight with the corresponding neighbour will decrease. Our results show that an appropriate aspiration level leads to a high-cooperation plateau, whereas too high or too low aspiration will impede the evolution of cooperation. We explain these findings with a comprehensive analysis of transition points and with a systematic analysis of typical configuration patterns. The presented results provide further theoretical insights with regards to the impact of different aspiration levels on cooperation in human societies.

1982-01-01

Over 200 consecutive diagnostic needle aspiration procedures of the abdomen were performed under computed tomographic (CT) guidance. Biopsies were done of the liver in 88 patients, the pancreas in 28, the kidney in 20, and the retroperitoneum in 32; 30 underwent an aspiration procedure for characterization of an intraabdominal fluid collection. Accuracy of diagnosis was very high for hepatic (99%) and renal (100%) biopsies and in characterization of fluid collections (100%). Accuracy for retroperitoneal biopsy was 87.5% and for pancreatic biopsy 82%. Overall accuracy for all sites was 95%. There were one false-negative diagnosis for the liver and five false-negative diagnoses for the pancreas. Insufficient material was obtained for diagnosis in four instances of retroperitoneal biopsy. There were no false positives. The technique is facilitated by rapid CT scan time, large aperture gantry, and rapid CT image reconstruction. Twenty gauge needles were used more frequently than 22 gauge needles because of their greater rigidity and ease of control. CT-guided diagnostic aspiration procedures are particularly useful for diagnosis of small, deep-seated lesions and in evaluation of lesions found in severely ill patients. An experienced cytologist is essential to the success of the technique

Glottal insufficiency with aspiration risk in dysphagia.

Science.gov (United States)

Giraldez-Rodriguez, Laureano A; Johns, Michael

2013-12-01

Glottal closure is an important part of the mechanism that protects the airway during the normal swallow. Glottal insufficiency disrupts glottal closure and therefore puts patients at risk of aspiration. Treatment of glottal insufficiency can be classified as surgical or nonsurgical. The objective of treating glottal insufficiency is to avoid aspiration or penetration of secretions or food into the airway. Nonsurgical treatment consists of swallowing maneuvers and other measures. Surgical treatment of glottal insufficiency includes injection laryngoplasty, medialization thyroplasty with or without arytenoid adduction or with arytenopexy and cricothyroid subluxation, hypopharyngoplasty, cricopharynx muscle dilation, and cricopharynx myotomy.

Inhalation of foreign bodies, a leading cause of accidental death, is most common in preschool children. In this article we report our experience with a 5-year-old Greek girl who presented with a 24-hour history of sore throat, chest pain, and shortness of breath. Emergency bronchoscopy was performed and multiple small chewing gummi bear (HARIBO) particles impacted in the orifices of the right main bronchus and right lobar and segmentalinic bronchi were successfully removed and aspirated. Aspiration of gummi bears, which is for the first time reported, may cause a silent choking episode leading to life-threatening bronchi obstruction at multiple sites, even in children older than 4 years.

Objective: To evaluate the efficacy of aspiration in an opposite position to deal with pneumothorax after CT-guided lung biopsy. Methods: A retrospective study was developed involving 210 patients with pneumothorax who had undergone CT-guided percutaneous core biopsies from January 2012 to March 2014 for various pulmonary lesions. Asymptomatic patients with minimal pneumothorax were treated conservatively. Simple manual aspiration was performed for symptomatic patients with minimal pneumothorax and for all patients with moderate to large pneumothorax. An opposite position aspiration was performed when simple manual aspiration failed. The efficacy of simple manual aspiration and the opposite position aspiration was observed. Results: Among 210 patients with pneumothorax, 128 (61.0%) asymptomatic patients with minimal pneumothorax were treated conservatively. The remaining 82 were treated with attempted simple manual aspiration. Out of these 82 patients, simple manual aspiration was successful in 58 (70.7%, 58/82) cases. The complete and partial regression rates were 17.2% (10/58) and 82.8% (48/58), respectively. In the other 24 patients (29.3%, 24/82), simple aspiration technique was ineffective. An opposite position (from prone to supine or vice versa) was applied, and a new biopsy puncture site was chosen for reaspiration. This procedure was successful in 22 patients but not in 2 patients who had to have a chest tube insertion. The complete and partial regression rates were 25.0% (6/24) and 66.7% (16/24), respectively. Applying the new method, the total effective rate of aspiration improved significantly from 70.7% (58/82) to 97.6% (80/82). Conclusion: The opposite position aspiration can be safe, effective and minimally invasive treatment for CT-guided lung biopsy-induced pneumothorax thus reducing the use of chest tube significantly. Advances in knowledge: (1) Opposite position aspiration can elevate the success rate of aspiration significantly (from 70.7% to 97

Analysis of feasibility, efficacy and short-term results after six-arm transvaginal mesh OPUR implantation in women with apical prolapse. The same surgeon operated all of 39 women using mesh OPUR. Preoperatively patients had a standardized interview and clinical examination. Intraoperative and postoperative complications were analyzed. Postoperative evaluation included standardized interview, clinical examination and standardized pelvic floor ultrasound performed with 2D transvaginal probe and 4D abdominal probe. There was no complication that needed operative intervention. Hematomas in 3 patients resolved spontaneously. Transient voiding difficulties which lasted less than 7 days were observed in 5 patients. No erosion was observed. Comparison of pre- and postoperative results in 34 women revealed that in all 3 compartments improvement in POP-Q scale was statistically significant (p mesh needed re-operation. During PFS-TV in 94.1% of patients urethra was normobile or hypermobile. In all of the patients urethral end of the mesh was positioned far enough from the middle part of the urethra (ultrasound) to implant suburethral sling without risk of collision. Sexually active women did not inform of any important discomfort or pain during intercourse. It seems that six-arm OPUR mesh, if implanted under strict surgical rules, gives low risk of complications and high chance to successfully reduce POP symptoms in short term after the operation. It seems that OPUR mesh should not have negative influence on the results after anti-incontinence suburethral sling.

Twenty-five patients with acute hypertensive intracerebral hematomas, diagnosed by computed tomography (CT), underwent CT-guided stereotactic aspiration. Magnetic resonance (MR) images were obtained immediately before aspiration, using T 1 -weighted (TR=500 msec, TE=15 msec) and T 2 -weighted (TR=2500 msec, TE=120 msec) sequences and a 0.5 Tesla MR system. On the basis of the MR images the hematomas were divided into peripheral, central, and core segments. The signal intensities were divided into seven grades based on the comparison with white matter. The sequential changes in each segment on the MR images were evaluated, and the ratio of hematoma removal vs. size of residual hematoma was assessed by preoperative MR imaging and pre-and post-operative CT. The hematomas were located in the putamen in 13 cases, the thalamus in 8, combined in 2, and subcortex in 2. The hematomas, targeted in their centers, were evacuated by the aspiration procedure alone, 1 to 12 days after onset (day 0=day of onset). The results were as follows : 1) The proportion of hematomas removed was high after day 4. 2) Sequential T 1 -weighted images showed that the peripheral segments gradually increased in signal intensity, appearing as high-intensity rings that gradually filled and could be easily aspirated. 3) In those cases in which sequential T 2 -weighted images showed the central segments gradually increasing in signal intensity, the hematomas were easily aspirated if the signal was either iso-intense or hyper-intense. 4) Several hematomas had a core that appeared as a high intensity signal on T1-weighted images and as a low intensity signal on T 2 -weighted images; these hematomas could not be aspirated.

To evaluate methods of CT-guided sacroiliac joint sampling in patients with suspected infection. All CT-guided sacroiliac joint sampling procedures for suspected infection were reviewed for sampling type (aspiration, lavage aspiration, biopsy), microbiology results, and clinical and imaging follow-up. The primary gold standard was anatomic pathology. If pathology was not available, then positive blood culture with the same organism as SIJ sampling, imaging and clinical follow-up, or clinical follow-up only were used. Anterior and posterior joint distention was evaluated by MRI within 7 days of the procedure. A total of 34 patients (age 39 ± 20 (range, 6-75) years; 21 F, 13 M) were included. Aspiration samples only were obtained in 13/34 (38%) cases, biopsy samples only in 9/34 (26%) cases, and both samples in 12/34 (35%) cases. There was an overall 54% sensitivity and 86% specificity. For the aspiration samples, sensitivity and specificity were 60 and 81%, respectively, compared to 45 and 90% for the biopsy samples. In cases with both samples, biopsy did not add additional microbial information. Seventeen (17/34, 50%) patients had an MRI. The anterior joint was more distended than the posterior joint in 15/17 (88%) of patients, and this difference was significant (P = 0.0003). All of these 17 patients had an attempted aspiration by a posterior approach; 6/17 (35%) resulted in a successful aspiration. Aspiration of the sacroiliac joint has a higher sensitivity than biopsy and should always be attempted first. MRI may be helpful for procedure planning.

We sought to track objective and subjective outcomes ≥1 year after transvaginal mesh system to correct prolapse. This was a retrospective cohort study of 120 women who received a transvaginal mesh procedure (Avaulta Solo, CR Bard Inc, Covington, GA). Outcomes were pelvic organ prolapse quantification values; Pelvic Floor Distress Inventory, Short Form 20/Pelvic Floor Impact Questionnaire, Short Form 7 scores; and a surgical satisfaction survey. "Surgical failure" was defined as pelvic organ prolapse quantification point >0, and/or any reports of vaginal bulge. Of 120 patients, 116 (97%) were followed up for a mean of 14.4 months (range, 12-30). In all, 74 patients had only anterior mesh, 21 only posterior mesh, and 21 both meshes. Surgical cure rate was 81%. Surgical failure was more common if preoperative point C ≥+2 (35% vs 16%; P = .04). Mesh erosion and de novo pain occurred in 11.7% and 3.3%, respectively. Pelvic Floor Distress Inventory, Short Form 20/Pelvic Floor Impact Questionnaire, Short Form 7 scores improved (P < .01). Objective and subjective improvements occurred at ≥1 year, yet failure rates were high when preoperative point C was ≥+2. Copyright © 2010 Mosby, Inc. All rights reserved.

Objective: To determine the re-biopsy rate, positive yield and safety profile of ultrasound guided fine needle aspiration cytology (FNAC) in cervical lymph nodes in terms of its complications and repeat procedures. Study Design: An analytical study. Place and Duration of Study: Department of Vascular and Interventional Radiology, Dow University Hospital, Dow University of Health Sciences, Karachi, from June to December 2013. Methodology: Eighty neck swellings, which were found to be lymph nodes on ultrasound, underwent ultrasound guided FNAC, from outpatients. Lymph nodes which were included in the study were those that were not easily palpable, located near major blood vessels, where patient refused of direct palpation and wanted image guided FNAC, those directly sent by physician for image guided FNAC and where blind biopsy remained inconclusive. Patients who refused on explanation or did not give consent were excluded. Complications and repeat biopsy were noted. Result: This study consisted of 80 cases, of which 51 cases (63.75 percentage) were female and 29 cases (36.25 percentage) were male. Repeat biopsy was required in 1 case (1.6 percentage). There were no procedure-related complications. A total of 44 cases (55 percentage) revealed evidence suggesting or confirming the existence of tuberculosis. Rest of the others showed other benign lesions, reactive lymphadenopathy and malignancy. Conclusion: Ultrasound guided FNAC is a safe procedure with low re-biopsy rate that aids diagnosis. The predominant cause of cervical lymphadenopathy in this study was tuberculous lymphadenitis. (author)

To determine the accuracy of changes in transvaginal sonographic cervical length over time in predicting preterm birth in women with singleton and twin gestations. PubMed, Embase, Cinahl, Lilacs, and Medion (all from inception to June 30, 2015), bibliographies, Google scholar, and conference proceedings. Cohort or cross-sectional studies reporting on the predictive accuracy for preterm birth of changes in cervical length over time. Two reviewers independently selected studies, assessed the risk of bias, and extracted the data. Summary receiver-operating characteristic curves, pooled sensitivities and specificities, and summary likelihood ratios were generated. Fourteen studies met the inclusion criteria, of which 7 provided data on singleton gestations (3374 women) and 8 on twin gestations (1024 women). Among women with singleton gestations, the shortening of cervical length over time had a low predictive accuracy for preterm birth at predictive accuracy for preterm birth at predictive accuracies for preterm birth of cervical length shortening over time and the single initial and/or final cervical length measurement in 8 of 11 studies that provided data for making these comparisons. In the largest and highest-quality study, a single measurement of cervical length obtained at 24 or 28 weeks of gestation was significantly more predictive of preterm birth than any decrease in cervical length between these gestational ages. Change in transvaginal sonographic cervical length over time is not a clinically useful test to predict preterm birth in women with singleton or twin gestations. A single cervical length measurement obtained between 18 and 24 weeks of gestation appears to be a better test to predict preterm birth than changes in cervical length over time.

Cooperation guided by the coexistence of imitation dynamics and aspiration dynamics in structured populations

In the framework of the evolutionary game theory, two fundamentally different mechanisms, the imitation process and the aspiration-driven dynamics, can be adopted by players to update their strategies. In the former case, individuals imitate the strategy of a more successful peer, while in the latter case individuals change their strategies based on a comparison of payoffs they collect in the game to their own aspiration levels. Here we explore how cooperation evolves for the coexistence of these two dynamics. Intriguingly, cooperation reaches its lowest level when a certain moderate fraction of individuals pick aspiration-level-driven rule while the others choose pairwise comparison rule. Furthermore, when individuals can adjust their update rules besides their strategies, either imitation dynamics or aspiration-driven dynamics will finally take over the entire population, and the stationary cooperation level is determined by the outcome of competition between these two dynamics. We find that appropriate synergetic effects and moderate aspiration level boost the fixation probability of aspiration-driven dynamics most effectively. Our work may be helpful in understanding the cooperative behavior induced by the coexistence of imitation dynamics and aspiration dynamics in the society.

The vascular resistant evaluation by Doppler waveform is a method used in clinic and research. The neoplastic malignant has an increased growth with an increased amount of neomalignant vessels. The presence of these vessels produce an increase of the transversal section area from the tumoral vascular system, therefore there is a decrease in the vascular resistance. The main objective of this work is to show the usefulness of Doppler waveform as predictor factor of malignity in ovary tumors. Eighteen patients with tumoral mass in the ovary were studied. They were between 21 and 67 years old (mean = 43). The tumoral volume and the flow resistance of blood vessels which irrigated those tumoral mass were evaluated by transvaginal ultrasound with color and pulsed Doppler. The pulsatility index (SD/media) was used. The Chi cuadrado test was used to evaluate the results. The results show the presence of six malignant tumors, three of them with low malignicity and the presence of twelve benign tumors. The age of the patients between both groups (malignant and benign tumors) were significant different (40.7 versus 52 years old, p < 0.001). The mean tumoral volume was 65 ml, with a range of 17 to 225 ml in the group of patients with benign tumors and the mean tumoral volume from patients with malignant tumors was 951 ml with a range of 141 to 3142 ml. The difference in the tumoral in both groups was significative with p < 0.001.(ABSTRACT TRUNCATED AT 250 WORDS)

This study investigated the novel associations between intrinsic and extrinsic aspirations and internal and external domains of contingent self-worth among a sample of 502 Iranian university students. We found a meaningful pattern showing that intrinsic aspirations were positively associated with internal domains, whereas extrinsic aspirations were positively associated with external domains. Our survey data also suggested that the factor structure of the Aspiration Index, as well as the factor structure of the Contingencies of Self-Worth Scale in our Iranian sample were consistent with factor structures of foreign samples. Finally, the types of aspirations and domains of contingencies of self-worth meaningfully predicted variables related to well-being, confirming previous research. We discuss the nature of the associations between the aspirations and the domains of contingent self-worth.

The study was undertaken to compare the clinical and quality-of-life (QoL) outcomes of the inside-out transobturator vaginal tape (TVT-O)-only procedures and TVT-O procedures with concomitant transvaginal gynaecological surgery for the treatment of stress urinary incontinence (SUI). A review of charts from January 2006 to March 2010 identified 305 patients with urodynamic stress incontinence for whom we performed the TVT-O. Of the initial 305 patients, 272 (89.2%) were re-examined for complications 1 month, 4 months, 1 year and 2-4 years postoperatively (122 TVT-O only; 150 TVT-O + other transvaginal gynaecological surgery). They were also evaluated with the Urogenital Distress Inventory Questionnaire (UDI-6) and the Incontinence Impact Questionnaire (IIQ-7) 1-4 years after the procedure. The median follow-up was 37.3 months. The success rate was 89.3% in the TVT-O-only group vs 93.3% in the TVT-O with concomitant gynaecological surgery group (p =0.729). The QoL score was quite good for 91.8% of the TVT-O-only patients and for 96.7% of the TVT-O with concomitant gynaecologic surgery patients (p =0.405). In conclusion, gynaecological operations performed concomitantly with the TVT-O procedure do not affect the clinical and QoL outcomes of the TVT-O procedure.

Sternal Aspiration of Bone Marrow in Dogs: A Practical Approach for Canine Leishmaniasis Diagnosis and Monitoring

Full Text Available Bone-marrow aspirate material is commonly considered as one of the most sensitive tissues for a reliable diagnosis of leishmaniasis. The procedure herein described may permit less experienced veterinarians to be familiar with a quick and safe assessment method for leishmaniasis diagnosis in their patients. Animals are positioned in right lateral recumbency, and the area corresponding to the second, third, or fourth sternebra is identified and aseptically prepared. A 18-gauge needle connected to a 10 mL syringe is driven through the skin, up to the bone wall, and firmly pushed forward while rotating. Entry into the sternebra’s cavity is clearly perceived by the fall of resistance offered by the cortex. Some 2,500 sternal bone-marrow samplings were safely and efficiently performed on 887 dogs of different breeds and aging from 6 months to 14 years, during eight years of clinical activity for routine diagnosis of canine leishmaniasis in pets or for the efficacy evaluation of anti-Leishmania immunobiologicals in dogs naturally exposed to parasite transmission. Most of the samples (1716 were from 387 dogs enrolled for anti-Leishmania vaccine studies. The safety of the method was particularly assessed on these dogs that as per study protocol were submitted to repeated bone-marrow aspirations (2–4 per year in follow-up examinations.

Despite recent decreases, homelessness remains a substantial problem in the United States. Homelessness is associated with poor health, and homeless women experience earlier mortality than their housed counterparts. Understanding the aspirations of homeless women may offer service providers avenues for intervention to increase well-being among this vulnerable population. This study, a secondary analysis of transcribed interviews (n = 20), provides insight into the aspirations of homeless women. Opportunities for service providers to intervene on these aspirations within the context of homelessness are offered.

2014-03-01

Full Text Available Foreign body aspiration is an urgent condition that requires immediate diagnosis and intervention. It is generally seen in children and in elderly patients with neurological problems and rarely seen in healthy adults. There may be some clinical signs and symptoms in patients with foreign body aspiration from mild to severe; such as cough, shortness of breath and respiratory arrest. A 52-year-old woman applied to our clinic with the complaints of cough and shortness of breath, and she was misdiagnosed and treated as asthma for three months. The chest radiograph showed heterogenous opacity in the right paracardiac region, computerized tomography revealed the foreign body aspiration in right main bronchus and peripheric pneumonia. Flexible bronchoscopy examination was processed and the foreign body was excluded safely with the aim of crocodile forceps. Foreign body aspiration should be kept in the mind in a adult patient with a sudden onset of asthma like disorder.

Our clinical experience suggested that elemental diets were associated with a reduction in aspiration pneumonia among bedridden patients with percutaneous endoscopic gastrostomy (PEG). We compared the effects of elemental and standard liquid diets on the risk of clinical aspiration pneumonia and gastric emptying in bedridden patients receiving PEG feedings. Study 1: consecutive bedridden PEG patients received elemental diets or standard liquid diets in the same fashion. The frequency of defecation, diet aspirated from the trachea, and aspiration pneumonia during hospitalization were prospectively recorded. Study 2: a randomized, crossover trial using elemental or standard liquid diets containing (13)C sodium acetate as a tracer given to bedridden PEG patients who had experienced aspiration pneumonia. (13)C breath tests were performed to estimate gastric emptying. Study 1: 127 patients were enrolled, 60 with elemental and 67 with standard liquid diets. The diet was aspirated from the trachea in none (0%) with the elemental diet vs. 8 (11.9%) with standard liquid diets (P=0.0057); aspiration pneumonia developed none with the elemental diet vs. 5 (7.5%) with standard liquid diets (P=0.031) (number needed to treat 14, 95% confidence interval 7-85). Study 2: 19 patients were enrolled. The elemental diet was associated with a significant increase in the 10, 30 or 50% emptying (excretion) time (Pbedridden PEG patients. They may be preferred for bedridden PEG patients especially who have experienced aspiration pneumonia. Properly performed randomized-controlled trials are needed to prove this potential benefit.

Aspiration past the tracheal tube cuff has been recognized to be a risk factor for the development of ventilator-associated pneumonia (VAP). This study investigated the effect of closed tracheal suctioning on aspiration of fluid past the tracheal tube cuff in an in vitro benchtop model. High-volume low pressure tube cuffs of 7.5 mm internal diameter (ID) were placed in a 22 mm ID artificial trachea connected to a test lung. Positive pressure ventilation (PPV) with 15 cm H₂O peak inspiratory pressure and 5 cm H₂O positive end-expiratory pressure (PEEP) was used. A closed tracheal suction system (CTSS) catheter (size 14Fr) was attached to the tracheal tube and suction was performed for 5, 10, 15, or 20 seconds under 200 or 300 cm H₂O suction pressures. Amount of fluid (mL) aspirated along the tube cuff and the airway pressure changes were recorded for each suction procedure. Fluid aspiration during different suction conditions was compared using Kruskal-Wallis and Mann-Whitney test (Bonferroni correction [α = .01]). During 10, 15, and 20 seconds suction, airway pressure consistently dropped down to -8 to -13 cm H₂O (P aspiration was never observed under PPV + PEEP but occurred always during suctioning. Aspiration along the tube cuff was higher with -300 cm H₂O than with -200 cm H₂O suction pressure (P aspiration of fluid occurs along the tracheal tube cuff during suction with the closed tracheal suction system. © SAGE Publications 2011.

Purpose This paper aims to test a model examining precursors and outcomes of nurses' leadership self-efficacy, and their aspirations to management positions. Design/methodology/approach A cross-sectional survey of 727 registered nurses across Canada was conducted. Structural equation modelling using Mplus was used to analyse the data. Findings Results supported the hypothesized model: χ 2 (312) = 949.393; CFI = 0.927; TLI = 0.919; RMSEA = 0.053 (0.049-0.057); SRMR 0.044. Skill development opportunities ( ß = 0.20), temporary management roles ( ß = 0.12) and informal mentoring ( ß = 0.11) were significantly related to nurses' leadership self-efficacy, which significantly influenced motivation to lead ( ß = 0.77) and leadership career aspirations ( ß = 0.23). Motivation to lead was significantly related to leadership career aspirations ( ß = 0.50). Practical implications Nurses' leadership self-efficacy is an important determinant of their motivation and intention to pursue a leadership career. Results suggest that nurses' leadership self-efficacy can be influenced by providing opportunities for leadership mastery experiences and mentorship support. Leadership succession planning should include strategies to enhance nurses' leadership self-efficacy and increase front-line nurses' interest in leadership roles. Originality value With an aging nurse leader workforce, it is important to understand factors influencing nurses' leadership aspirations to develop and sustain nursing leadership capacity. This research study makes an important contribution to the nursing literature by showing that nurses' leadership self-efficacy appears to be an important determinant of their motivation to lead and desire to pursue a career as a nurse leader.

Objective Examine the incidence of penetration/aspiration in patients with unilateral vocal fold immobility and investigate the relationship with self-reported perception of dysphagia. Study Design Case series with chart review. Setting Academic cancer center. Subjects and Methods Adult patients with unilateral vocal fold immobility diagnosed between 2014 and 2016 were reviewed. Patients were stratified into an aspiration group and a nonaspiration group using objective findings on flexible endoscopic evaluation of swallowing, as scored using Rosenbek's Penetration Aspiration Scale. Objective findings were compared to patient perception of dysphagia. Bivariate linear correlation analysis was performed to evaluate correlation between Eating Assessment Tool-10 scores and presence of aspiration. Tests of diagnostic accuracy were calculated to investigate the predictive value of Eating Assessment Tool-10 scores >9 on aspiration risk. Results Of the 35 patients with new-onset unilateral vocal fold immobility were evaluated, 25.7% (9/35) demonstrated tracheal aspiration. Mean ± SD Eating Assessment Tool-10 scores were 19.2 ± 13.7 for aspirators and 7.0 ± 7.8 for nonaspirators ( P = .016). A statistically significant correlation was demonstrated between increasing Eating Assessment Tool-10 scores and Penetration Aspiration Scale scores ( r = 0.511, P = .002). Diagnostic accuracy analysis for aspiration risk in patients with an Eating Assessment Tool-10 score >9 revealed a sensitivity of 77.8% and a specificity of 73.1%. Conclusion Patient perception of swallowing difficulty may have utility in predicting aspiration risk. An EAT-10 of >9 in patients with unilateral vocal fold immobility may portend up to a 5 times greater risk of aspiration. Routine swallow testing to assess for penetration/aspiration may be indicated in patients with unilateral vocal fold immobility.

Measurement of Oxygen Desaturation Is Not Useful for the Detection of Aspiration in Dysphagic Stroke Patients

Directory of Open Access Journals (Sweden)

Thomas Marian

2017-03-01

Full Text Available Background: Dysphagia is one of the most dangerous symptoms of acute stroke. Various screening tools have been suggested for the early detection of this condition. In spite of conflicting results, measurement of oxygen saturation (SpO2 during clinical swallowing assessment is still recommended by different national guidelines as a screening tool with a decline in SpO2 ≥2% usually being regarded as a marker of aspiration. This paper assesses the sensitivity of SpO2 measurements for the evaluation of aspiration risk in acute stroke patients. Methods: Fifty acute stroke patients with moderate to severe dysphagia were included in this study. In all patients, fiberoptic endoscopic evaluation of swallowing (FEES was performed according to a standardised protocol. Blinded to the results of FEES, SpO2 was monitored simultaneously. The degree of desaturation during/after swallows with aspiration was compared to the degree of desaturation during/after swallows without aspiration in a swallow-to-swallow analysis of each patient. To minimise potential confounders, every patient served as their control. Results: In each subject, a swallow with and a swallow without aspiration were analysed. Overall, aspiration seen in FEES was related to a minor decline in SpO2 (mean SpO2 without aspiration 95.54 ± 2.7% vs. mean SpO2 with aspiration 95.28 ± 2.7%. However, a significant desaturation ≥2% occurred only in 5 patients during/after aspiration. There was no correlation between aspiration/dysphagia severity or the amount of aspirated material and SpO2 levels. Conclusions: According to this study, measurement of oxygen desaturation is not a suitable screening tool for the detection of aspiration in stroke patients.

The role of ultrasonography (US) as an initial screening test was evaluated in 3000 consecutive cases of blunt abdominal trauma (BAT). Seventy-three were positive for free fluid collection or organ injury. US-guided aspiration was used to rule out the hollow visceral injury in those referred to nonsurgical therapy. Sixty patients underwent laparotomy. These included 53 clinically unstable patients, three stable patients with positive US-guided aspiration for bile or intestinal contents and four who deteriorated upon conservative treatment. The remaining patients with US negative for fluid had some evidence of abdominal injury on clinical examination. Ultrasonoraphy complemented the clinical examination. Both the sensitivity and specificity of US for the detection of free fluid were 100%. The overall sensitivity was 92% in spleen injuries, 88% in liver injuries and 100% in kidney injuries, with positive predictive value of 96%, 100% and 100% and a specificity of 97%, 100% and 100% respectively. Retrospective correlation of US with laparotomy findings regarding free fluid showed that 50-100 mL of free fluid was minimal, 100-500 mL significant. Thirteen patients completed conservative treatment with an uneventful course in hospital. Both the US findings and the clinical condition of the patient should be considered in decision-making in BAT. Unnecessary laparotomies can be avoided when the major bleeding site is not in the abdomen and such patients can be safely observed after excluding the hollow visceral injury by US-guided aspiration. US, being rapid to perform, sensitive and easily repeatable, is quite useful as an initial screening test in BAT patients. (author)

To evaluate the outcome and assess the success rate of ultrasound guided aspiration of breast abscess as an alternative to surgical incision and drainage. Methodology: A prospective descriptive study was carried out at Department of Surgery, Chandka Medical College Hospital, Larkana, Pakistan, from January 2015 to December 2015. A total of 111 patients of breast abscess who underwent ultrasound guided aspiration without anesthesias with oral antibiotic cover were studied. Females with breast abscess within seven days, and the abscess size was <3cm were included in the study. Males, antibioma and inflammatory carcinoma were excluded from the study. Outcome of success or failure was observed within two weeks and recorded. Results: Out of 111 patients, 68.46% were lactating and 31.53% were non-lactating women, with ages ranging from 18 to 60 years (mean 36.5 years). The successful rate with complete resolution after ultrasound guided aspiration was observed in 94.5%. 80.82% responded after single aspiration, 12.38% after two times aspiration, and 6.66% after multiple aspirations, while 5.4% of patients required incision and drainage. Conclusion: Ultrasound guided aspiration of breast abscess is an effective treatment option with a diameter of <3cm, which can be recommended as a routine outpatient procedure. (author)

The objective was to evaluate if existence of hydrothorax in initial chest radiograph predicts treatment outcome in patients with primary spontaneous pneumothorax who received needle thoracostomy. This is a retrospective cohort study carried out from January 2011 to August 2014 in 1 public hospital in Hong Kong. All consecutive adult patients aged 18years or above who attended the emergency department with the diagnosis of primary spontaneous pneumothorax with needle aspiration performed as primary treatment were included. Age, smoking status, size of pneumothorax, previous history of pneumothorax, aspirated gas volume and presence of hydropneumothorax in initial radiograph were included in the analysis. The outcome was success or failure of the needle aspiration. Logistic regression was used to identify the predicting factors of failure of needle aspiration. There were a total of 127 patients included. Seventy-three patients (57.5%) were successfully treated with no recurrence upon discharge. Among 54 failure cases, 13 patients (10.2%) failed immediately after procedure as evident by chest radiograph and required second treatment. Forty-one patients (32.3%) failed upon subsequent chest radiographs. Multivariate logistic regression showed factors independently associated with the failure of needle aspiration, which included hydropneumothorax in the initial radiograph (odds ratio [OR]=4.47 [1.56i12.83], P=.005), previous history of pneumothorax (OR=3.92 [1.57-9.79], P=.003), and large size of pneumothorax defined as apex-to-cupola distance ≥5cm (OR=2.75 [1.21-6.26], P=.016). Hydropneumothorax, previous history of pneumothorax, and large size were independent predictors of failure of needle aspiration in treatment of primary spontaneous pneumothorax.

Loss of protective airway reflexes in patients with acute coma puts these patients at risk of aspiration pneumonia complicating the course of the primary disease. Available data vary considerably with regard to bacteriology, role of anaerobic bacteria, and antibiotic treatment. Our objective was to research the bacteriology of aspiration pneumonia in acute coma patients who were not pre-treated with antibiotics or hospitalized within 30 days prior to the event. We prospectively analyzed 127 patient records from adult patients admitted, intubated and ventilated to a tertiary medical intensive care unit with acute coma. Bacteriology and antibiotic resistance testing from tracheal aspirate sampled within 24 h after admission, blood cultures, ICU scores (APACHE II, SOFA), hematology, and clinical chemistry were assessed. Patients were followed up until death or hospital discharge. The majority of patients with acute coma suffered from acute cardiovascular disorders, predominantly myocardial infarction, followed by poisonings, and coma of unknown cause. In a majority of our patients, microaspiration resulted in overt infection. Most frequently S. aureus, H. influenzae, and S. pneumoniae were isolated. Anaerobic bacteria (Bacteroides spec., Fusobacteria, Prevotella spec.) were isolated from tracheal aspirate in a minority of patients, and predominantly as part of a mixed infection. Antibiotic monotherapy with a 2nd generation cephalosporin, or a 3rd generation gyrase inhibitor, was most effective in our patients regardless of the presence of anaerobic bacteria.

Metastatic brain tumors over 3 cm in diameter (volume of 14.1ml) are generally considered poor candidates for Gamma Knife surgery (GKS). We retrospectively assessed the method and efficacy of GKS for large cystic metastatic brain tumors after navigation-guided aspiration under local anesthesia. From September 2007 to April 2014, 38 cystic metastatic brain tumors in 32 patients (12 males, 20 females; mean age, 63.2 years) were treated at Kansai Rosai Hospital. The patients were performed navigation-guided cyst aspiration under local anesthesia, then at the day or the next day, were performed GKS and usually discharged on the day. The methods for preventing of leptomeningeal dissemination are following: 1) puncture from the place whose cerebral thickness is 1 cm or more; 2) avoidance of Ommaya reservoir implantation; and 3) placement of absorbable gelatin sponge to the tap tract. Tumor volume, including the cystic component, decreased from 25.4 ml (range 8.7-84.7 ml) to 11.4 ml (range 2.9-36.7 ml) following aspiration; the volume reduction was approximately 51.6%. Follow-up periods in the study population ranged from 0 to 24 months (median 3.5 months). The overall median survival was 6.7 months. There was no leptomeningeal dissemination related to the aspiration. One patient experienced radiation necrosis after GKS, one patient experienced re-aspiration by failure of aspiration, and two patients experienced surgical resections and one patient experienced re-aspiration by cyst regrowth after GKS. Long-term hospitalization is not desirable for the patients with brain metastases. In japan, Long-term hospitalization is required for surgical resection or whole brain radiation therapy, but only two days hospitalization is required for GKS after navigation-guided aspiration at our hospital. This GKS after navigation-guided aspiration is more effective and less invasive than surgical resection or whole brain radiation therapy.

Full Text Available Housing aspiration is an important aspect of housing market analysis. However, there is a paucity of empirical research on housing aspiration among residents in informal settlements in developing countries. This study therefore investigated housing aspiration among the residents of Ayobo, Lagos, Nigeria. A cross-sectional survey of 1,151 households in Ayobo was conducted using a structured questionnaire as the data-collection instrument. The data were analysed using descriptive statistical and categorical regression analyses. The results show that a majority of the respondents were low-income earners living in rented and rooming-house types of accommodation. Around 73% of them expressed an intention to move to another residence, and 56% of this category of respondents intend to move into self-contained flats. The reasons for the planned relocation include poor condition of their present dwellings, changes in tenure status and household size, and the desire for exclusive use of facilities in their homes. In addition to these reasons, the waste-disposal method, sharing facilities, employment, and age and marital status of the residents emerged as the strongest predictors of housing aspiration among the respondents in the survey. This implies that, in order to meet the housing preferences and aspirations of residents in informal urban settlements in Nigeria, housing developers need to give adequate attention to the marital, age, employment and tenure status of the residents and place emphasis on developing affordable single-family houses and block of flats, as well as strategies for improving access to basic social amenities and services.

2013-04-01

To measure the efficiency of phacoemulsification, we have developed a new experimental model for testing phaco-efficiency and analyzed re-aspiration of repulsed particles. Using a Kitaro wetlab system, a piece of blood agar (BA) was placed in an artificial chamber and the phacoemulsifier was placed horizontally. The settings of the phacoemulsifier (Infiniti, Alcon Laboratories) were 26 cc/min for aspiration, 350 cc/min for vacuum, and 95 cm of bottle height. The time to remove BAs was measured using Ozil 100 %, Ozil 40 %, and longitudinal 40 % of phaco power. The angle between the re-aspirated BA particles and the axis of the phacoemulsifier (re-aspiration zone, degree) was analyzed. The average time (seconds) to remove BAs was lower in the Ozil 100 % and the Ozil 40 % mode than in the longitudinal mode (0.37 ± 0.39, 0.85 ± 0.57, and 2.22 ± 1.40 respectively, P value < 0.01). Repulsion exceeding 1 mm occurred more frequently in the longitudinal mode than in the Ozil 100 % mode (100 % vs 40 %, P value = 0.01, Fisher's exact test). The average of re-aspiration zone was 25.9 ± 14.5 in the longitudinal 40 % and 54.0 ± 23.0 in the Ozil 40 % (P value = 0.016). The Ozil mode was more efficient than the longitudinal mode. In addition, the Ozil mode provided less repulsion and wider aspiration zone.

Profound oropharyngeal dysphagia (OPD) is common and costly. Treatment options are limited. The purpose of this investigation was to evaluate the utility of hypopharyngeal suction at the upper esophageal sphincter (UES) to eliminate aspiration. Five different catheters were passed retrograde up the esophagus and positioned at the UES in a cadaver model of profound OPD. Suction was affixed to each catheter. 10 cc of barium was administered into the pyriform sinus, and videofluoroscopy was utilized to evaluate the presence of aspiration. 6 trials were administered per catheter and for a no catheter control. The outcome measures were the incidence of aspiration, the NIH Swallow Safety Scale (NIH-SSS), and UES opening. Control trials with no suction resulted in an aspiration rate of 100 % (6/6 trials). Negative pressure through 16, 18, 24, and 30 Fr catheter resulted in an aspiration rate of 0 % (0/24 trials; p  0.05). The mean NIH-SSS improved from 7.0 (±0.0) in the control to 0 (±0.0) with hypopharyngeal suction (18 Fr nasogastric catheter; p 12 Fr) at the level of the UES reduced aspiration by 100 % and significantly increased UES opening in a cadaveric model of profound oropharyngeal dysphagia.

To review foreign body aspiration cases encountered over a 10-year period in a tertiary paediatric hospital, and to assess correlation between foreign body type and language spoken at home. Retrospective chart review of all children undergoing direct laryngobronchoscopy for foreign body aspiration over a 10-year period. Age, sex, foreign body type, complications, hospital stay and home language were analysed. At direct laryngobronchoscopy, 132 children had foreign body aspiration (male:female ratio 1.31:1; mean age 32 months (2.67 years)). Mean hospital stay was 2.0 days. Foreign bodies most commonly comprised food matter (53/132; 40.1 per cent), followed by non-food matter (44/132; 33.33 per cent), a negative endoscopy (11/132; 8.33 per cent) and unknown composition (24/132; 18.2 per cent). Most parents spoke English (92/132, 69.7 per cent; vs non-English-speaking 40/132, 30.3 per cent), but non-English-speaking patients had disproportionately more food foreign bodies, and significantly more nut aspirations (p = 0.0065). Results constitute level 2b evidence. Patients from non-English speaking backgrounds had a significantly higher incidence of food (particularly nut) aspiration. Awareness-raising and public education is needed in relevant communities to prevent certain foods, particularly nuts, being given to children too young to chew and swallow them adequately.

2000-01-01

To Analyze the transvaginal ultrasonographic(TVUS)findings of the cystic adnexal masses in postmenopausal women for differentiation of benign and malignant masses. We retrospectively reviewed the TVUS images of surgically proven 142 cystic adnexal masses in 125 patients. The masses were classified according to the pathologic findings. The size, the internal echogenicity, the internal septation, the external wall of the masses on US were analyzed and scored using Multicenter scoring system. Serum CA-125 concentration was also recorded. At surgery of 142 masses, 125 benign (88%), and 17 borderline/malignant masses (12%) were found. Among 125 benign masses, 88 masses were larger than 5 cm, 125 had smooth external wall, 109 had absence or thin internal septation, and 107 had anechoic or homogenous low internal echogenicity. Of the 17 borderline/malignant masses, there were 17 masses larger than 5 cm, 2 with smooth external wall, 12 without or with thin internal septation, and 7 with anechoic or homogenous low internal echogenicity. Multicenter score was below 8 in all benign masses, and in 4 borderline/malignant masses. Serum CA-125 concentration with normal range was in 90 patients with benign masses, and in 2 patients with borderline/malignant masses. Cystic adnexal masses with smooth external wall and internal septation, internal echogenic portion less than 10%, score below 8 on TVUS would be diagnosed as benign masses in postmenopausal women with normal serum CA-125 concentration.

Current situation of transvaginal mesh repair for pelvic organ prolapse.

Science.gov (United States)

Zhu, Lan; Zhang, Lei

2014-09-01

Surgical mesh is a metallic or polymeric screen intended to be implanted to reinforce soft tissue or bone where weakness exists. Surgical mesh has been used since the 1950s to repair abdominal hernias. In the 1970s, gynecologists began using surgical mesh products to indicate the repair of pelvic organ prolapse (POP), and in the 1990s, gynecologists began using surgical mesh for POP. Then the U.S. Food and Drug Administration (FDA) approved the first surgical mesh product specifically for use in POP. Surgical mesh materials can be divided into several categories. Most surgical mesh devices cleared for POP procedures are composed of non-absorbable synthetic polypropylene. Mesh can be placed in the anterior vaginal wall to aid in the correction of cystocele (anterior repair), in the posterior vaginal wall to aid in correction of rectocele (posterior repair), or attached to the top of the vagina to correct uterine prolapse or vaginal apical prolapse (apical repair). Over the past decades, surgical mesh products for transvaginal POP repair became incorporated into "kits" that included tools to aid in the delivery and insertion of the mesh. Surgical mesh kits continue to evolve, adding new insertion tools, tissue fixation anchors, surgical techniques, and ab- sorbable and biological materials. This procedure has been performed popularly. It was also performed increased in China. But this new technique met some trouble recently and let shake in urogynecology.

2017-06-07

Objective: To evaluate the efficacy of cuffed tracheostomy tube with inner cannula for the treatment of intractable aspiration after partial laryngectomy. Methods: From May 2010 to June 2015, 15 patients with intractable aspiration after partial laryngectomy of laryngeal and hypopharyngeal carcinoma were enrolled. Cuffed tracheostomy tube with inner cannula was used in the 15 patients for treatment of intractable aspiration. The patients and their family were trained to manage the cuffed tracheostomy tube with inner cannula and to eat since the 14th day after surgery. Cuff was initially inflated with 10 ml air and then deflated of 0.5 ml air every 2-3 days. Until the inflation of cuff was no longer required, the cuffed tracheostomy tube was replaced by metal tracheostomy tube. The patients' swallowing function and aspiration were evaluated 6 months after treatment. Results: The 15 cases with intractable aspiration were treated with cuffed tracheostomy tube with inner cannula and after 2-3 months, 14 of them replaced the cuffed tracheostomy tubes with inner cannula by metal tracheostomy tubes and recovered oral eating, and tracheostomy tubes were no longer required for 12 of 14 patients in following 3-6 months, showing a total decannulation rate of 80% in the patients with refractory aspiration. Conclusion: It was safe and effective to treat aspiration after laryngeal and hypopharyngeal surgery with cuffed tracheostomy tube with inner cannula.

Sandberg, Jason M; Gray, Ian; Pearlman, Amy; Terlecki, Ryan P

2018-03-01

To assess the utility of the Manufacturer And User Facility Device Experience (MAUDE) database in objectively capturing adverse events for transvaginal mesh in the United States. We reviewed 1,103 individual medical device reports submitted to the MAUDE database that inspired the United States (US) Food and Drug Administration's 2008 Public Health Notification. Entries were compiled into a categorical database that reported manufacturer, brand, reporter type, report source, and type of adverse event. There were numerous examples of missing, duplicated, and non-standardized entries. Analysis revealed 64 reports with duplicated information, and six reports representing multiple patients. Forty-seven percent of medical device reports did not identify a reporter source. At least 28% of reported devices are no longer on the US market. There was wide variability in the quality and completeness of submitted reports and true adverse event rates could not be accurately calculated because the number of total cases was unknown. The MAUDE database was limited in its ability to collect, quantify, and standardize real-life adverse events related to transvaginal mesh. While it functions to collect information related to isolated adverse events, systematic limitations of the MAUDE database, that no doubt extend to other medical devices, necessitate the development of new reporting systems. Alternatives are under development, which may allow regulators to more accurately scrutinize the safety profiles of specific medical devices.

Full Text Available Background: Aspiration pneumonia is a potentially preventable illness requiring attention to small details of patient care. The type, management, and care of feeding should be carried out properly. Materials andMethods: This is a prospective clinical study of enteral feeding on patients admitted to hospital with aspiration pneumonia. The known enteral nutritional methods, advantages, and disadvantages were told to the patient or proxy. If they didn′t accept Percutaneous endoscopic gastrostomy (PEG, nasojejunal tube (NJT was advised. If they denied all of the procedures, oral feeding education was given. A total of 94 patients were enrolled to the study, 29 of them accepted PEG, 42 preferred NJT, and 23 preferred oral route. Results: A total of 94 patients with a mean age of 77.84, standard deviation 10.784; 95% confidence interval (CI 75.63-80.03 were enrolled to the study of which 27 (28.7% patients had a history of aspiration pneumonia.

Culture positivity of percutaneous aspiration material" is not included in the current bacteriological criteria for diagnosis of pulmonary nontuberculous mycobacterial (NTM) diseases, which were published by the Infectious Diseases Society of America (IDSA)/American Thoracic Society (ATS) in 2007 or those released by the Japanese Society for Tuberculosis in 2008. However, percutaneous aspiration is a reliable technique for the detection of causative microorganisms isolated from the focus of infection. We discuss the benefits of including positive culture of percutaneous aspiration material in the bacteriological diagnostic criteria of pulmonary NTM diseases. We reviewed the radiological images and clinical courses of pulmonary diseases in which NTM cultures were obtained from percutaneously aspirated materials at our hospital from 1991 to 2011. Aspiration was carried out under local anesthesia, usually with fluoroscopic guidance. After percutaneous insertion of a 22-gauge needle attached to a 20-mL syringe containing about 3 mL of saline, the lesion specimen was withdrawn together with the saline. After the needle was pulled out, the aspirated material and saline were transferred to test tubes for cytological and microbiological examinations. In patients with thin-walled cavitary lesions, saline was injected into the cavity and then aspirated. Percutaneous aspiration was performed in 2,742 patients and NTM disease was detected in 51 patients. Of these 51 patients, 12 had solitary nodular lesions, and in many of these patients, no NTM bacilli could be detected in the sputa or bronchial washing specimens. Mycobacterium avium was identified in 10 of the 12 cases. Four of these 10 patients were followed up after their diagnosis without any treatment: 3 showed spontaneous reduction in lesion size, while 1 patient's condition remained unchanged. Four of the remaining 6 cases were treated with anti-NTM medications, and lesion size reduced in 2 cases, while no change or

To describe the correlation between the functional dysphagia scale and aspiration pneumonia and which characteristics influence the occurrence of aspiration pneumonia in patients with idiopathic Parkinson disease. Fifty-three patients with idiopathic Parkinson disease were prospectively evaluated in this study. Disease severity and functional status were measured by modified Hoehn and Yahr (H&Y) staging, Schwab and England activities of daily living (S-E ADL) scale and Korean version of Mini-Mental State Examination (K-MMSE). Swallowing function was evaluated by the functional dysphagia scale (FDS) and the penetration-aspiration scale (PAS) based on a videofluoroscopic swallowing study. The patients were followed up for 3 months and divided into two groups according to the occurrence of aspiration pneumonia. The correlation between the variables and aspiration pneumonia was analyzed. Eight patients of the 53 patients were allocated to the aspiration pneumonia group and 45 patients to the non-aspiration pneumonia group. The patients in the aspiration pneumonia group had significantly higher H&Y staging, and scored lower on S-E ADL scale and K-MMSE. The patients in the aspiration pneumonia group had significantly higher scores on FDS and PAS. A multiple logistic regression analysis showed that the S-E ADL scale and the FDS were associated with the occurrence of aspiration pneumonia in the patients with Parkinson disease. Given that the FDS can quantitatively assess the functional problems associated with dysphagia, it can be clinically effective in predicting the occurrence of aspiration pneumonia, and the FDS and the S-E ADL scale could be predictive variables for aspiration pneumonia in patients with Parkinson disease.

Airway protections is the prevention and/or removal of material by behaviors such as cough and swallow. We hypothesized these behaviors are coordinated to respond to aspiration. Anesthetized animals were challenged with simulated aspiration that induced both coughing and swallowing. Electromyograms of upper airway and respiratory muscles together with esophageal pressure were recorded to identify and evaluate cough and swallow. During simulated aspiration, both cough and swallow intensity increased and swallow duration decreased consistent with rapid pharyngeal clearance. Phase restriction between cough and swallow was observed; swallow was restricted to the E2 phase of cough. These results support three main conclusions: 1) the cough and swallow pattern generators are tightly coordinated so as to generate a protective meta-behavior; 2) the trachea provides feedback on swallow quality, informing the brainstem about aspiration incidences; and 3) the larynx and upper esophageal sphincter act as two separate valves controlling the direction of positive and negative pressures from the upper airway into the thorax.

The physiological changes associated with pregnancy may predispose pregnant women to pulmonary edema. Other known causes of pulmonary edema during pregnancy include tocolytic drugs, preeclampsia, eclampsia, and peripartum cardiomyopathy. We describe a rare case of pulmonary edema caused by takotsubo cardiomyopathy in a pregnant woman at 14 weeks of gestation who was undergoing emergency transvaginal cervical cerclage. Intraoperative chest radiography revealed severe pulmonary edema and echocardiography indicated moderate left ventricular dysfunction with akinesia of the mid to apical left ventricular wall segment, which is reflective of takotsubo cardiomyopathy. With early detection and appropriate management, the patient was stabilized in a relatively short period of time. Based on her clinical signs and symptoms, we suspect that the pulmonary edema was caused by takotsubo cardiomyopathy.

Objective: To describe the clinical manifestations and bronchoscopic treatment of foreign body aspiration in children under 14 years of age, correlating the clinical aspects with the bronchoscopic findings. Methods: A retrospective, descriptive study analyzing data related to children under 14 years of age undergoing bronchoscopy due to clinical suspicion of foreign body aspiration at the State University at Campinas Hospital das Clinicas from January of 2000 to December of 2005. Results: The sample consisted of 69 patients, ranging in age from 8 months to 12 years/7 months (75.4% under 3 years of age), 62.3% of whom were male. The principal complaint was sudden-onset cough (75.4%), auscultation was abnormal in 74%, and dyspnea was observed in 29%. Radiological abnormalities were seen in 88% of the cases. Aspirations were primarily into the right lung (54.8%), and 30.7% of the foreign bodies were of vegetal origin (principally beans and peanuts). In the follow-up period, 29% presented complications (most commonly pneumonia), which were found to be associated with longer aspiration time (p = 0.03). Mechanical ventilation was required in 7 children (10.1%), and multiple bronchoscopies were performed in 5 (7.2%). Conclusions: A history of sudden-onset choking and cough, plus abnormal auscultation and radiological findings, characterizes the profile of foreign body aspiration. In such cases, bronchoscopy is indicated. Longer aspiration time translates to a higher risk of complications. The high prevalence of foreign bodies of vegetal origin underscores the relevance of prevention at children younger than three years of age. (author)

Cervical auscultation could improve the performance of bedside swallowing test to predict aspiration, especially silent aspiration. The aim of this study is to compare the predictive values of bedside swallowing test performed with and without cervical auscultation by logopedist students who had intensive training on cervical auscultation. 64 patients were included in the study. They all underwent swallowing test alone, combined swallowing test and cervical auscultation, and videofluoroscopic swallowing study as defined gold standard. Two logopedist students, at the end of their training, performed the auscultation and noted their results. 128 tests were performed, 96% of the tests were judged positive for aspiration. When comparing the results of the two different clinical tests, the detection of clinical signs is not improved by the addition of auscultation. Using a penetration aspiration scale threshold >5, the area under the curve measured for the swallowing test alone was significantly higher than that measured for the combined tests (p = 0.03) (0.66 for the swallowing test alone (95% CI between 0.49 and 0.83), and 0.50 for the combined tests (95% CI between 0.31 and 0.69). This study showed no advantage in performing cervical auscultation with bedside swallowing test. Cervical auscultation seems to hamper the assessment, mainly the perception of wet voice and laryngeal motion. These results are compatible with literature but need further confirmation using studies performed with trained logopedists.

It is uncertain whether amnioinfusion (infusion of saline into the amniotic cavity) in women who have thick meconium staining of the amniotic fluid reduces the risk of perinatal death, moderate or severe meconium aspiration syndrome, or both. We performed a multicenter trial in which 1998 pregnant women in labor at 36 or more weeks of gestation who had thick meconium staining of the amniotic fluid were stratified according to the presence or absence of variable decelerations in fetal heart rate and then randomly assigned to amnioinfusion or to standard care. The composite primary outcome measure was perinatal death, moderate or severe meconium aspiration syndrome, or both. Perinatal death, moderate or severe meconium aspiration syndrome, or both occurred in 44 infants (4.5 percent) of women in the amnioinfusion group and 35 infants (3.5 percent) of women in the control group (relative risk, 1.26; 95 percent confidence interval, 0.82 to 1.95). Five perinatal deaths occurred in the amnioinfusion group and five in the control group. The rate of cesarean delivery was 31.8 percent in the amnioinfusion group and 29.0 percent in the control group (relative risk, 1.10; 95 percent confidence interval, 0.96 to 1.25). For women in labor who have thick meconium staining of the amniotic fluid, amnioinfusion did not reduce the risk of moderate or severe meconium aspiration syndrome, perinatal death, or other major maternal or neonatal disorders.

The purpose of this study was to determine the complications, treatments, and outcomes in patients choosing to undergo removal of mesh previously placed with a mesh procedural kit. This was a retrospective review of all patients who underwent surgical removal of transvaginal mesh for mesh-related complications during a 3-year period at Cleveland Clinic. At last follow-up, patients reported degree of pain, level of improvement, sexual activity, and continued symptoms. Nineteen patients underwent removal of mesh during the study period. Indications for removal included chronic pain (6/19), dyspareunia (6/19), recurrent pelvic organ prolapse (8/19), mesh erosion (12/19), and vesicovaginal fistula (3/19), with most patients (16/19) citing more than 1 reason. There were few complications related to the mesh removal. Most patients reported significant relief of symptoms. Mesh removal can be technically difficult but appears to be safe with few complications and high relief of symptoms, although some symptoms can persist.

Though open surgical biopsy is the procedure of choice for the diagnosis of bone tumors, many disadvantages are associated with this approach. The present study was undertaken to evaluate the role of fine needle aspiration cytology (FNAC) as a diagnostic tool in cases of bony tumors and tumor-like lesions which may be conducted in centers where facilities for surgical biopsies are inadequate. The study population consisted of 51 cases presenting with a skeletal mass. After clinical evaluation, radiological correlation was done to assess the nature and extent of each lesion. Fine needle aspiration was performed aseptically and smears were prepared. Patients subsequently underwent open surgical biopsy and tissue samples were obtained for histopathological examination. Standard statistical methods were applied for analysis of data. Adequate material was not obtained even after repeated aspiration in seven cases, six of which were benign. Among the remaining 44 cases, diagnosis of malignancy was correctly provided in 28 (93.3%) out of 30 cases and categorical diagnosis in 20 (66.67%). Interpretation of cytology was more difficult in cases of benign and tumor-like lesions, with a categorical opinion only possible in seven (50%) cases. Statistical analysis showed FNAC with malignant tumors to have high sensitivity (93.3%), specificity (92.9%) and positive predictive value of 96.6%, whereas the negative predictive value was 86.7%. FNAC should be included in the diagnostic workup of a skeletal tumor because of its simplicity and reliability. However, a definitive pathologic diagnosis heavily depends on compatible clinical and radiologic features which can only be accomplished by teamwork. The cytological technique applied in this study could detect many bone tumors and tumor-like conditions and appears particularly suitable as a diagnostic technique for rural regions of India as other developing countries.

Surfactant therapy for maternal blood aspiration: an unusual cause of neonatal respiratory distress syndrome.

Surfactant replacement therapy is the main treatment of neonatal respiratory distress syndrome. However, surfactant therapy has been shown to be effective in the treatment of other diseases causing neonatal respiratory diseases such as pulmonary hemorrhage, meconium aspiration syndrome, pneumonia/sepsis, pulmonary edema or acute lung injury resulting a secondary surfactant deficiency (SSD). Rarely, as like as in the present patient, exogenous blood aspiration such as breast milk or formula aspiration may lead to SSD. Blood in alveolus leads to a significant biochemical and functional disturbance of the surfactant system and inhibits surfactant production. Here, the authors report a preterm infant of 33 wk gestational age with secondary surfactant deficiency due to maternal blood aspiration because of abruptio placentae. She was received two courses of beractant, a natural bovine surfactant, therapy in 24 h. She was extubated on second day and did not require oxygen on 4(th) day. To the authors' knowledge, this is the first reported case of SSD due to maternal blood aspiration treated with surfactant. In conditions such as abruptio placentae, infant should be protected from blood aspiration and if respiratory distress occurs, surfactant inhibition and need for surfactant administration should be considered.

This study aims to investigate the correlation between α-amylase in tracheal aspirates and risk factors of aspiration, as well as ventilator-associated pneumonia (VAP), in elderly patients undergoing mechanical ventilation and explore the clinical value of α-amylase for predicting VAP. Tracheal aspirates were collected from elderly patients within 2 weeks after tracheal intubation in mechanical ventilation, and α-amylase was detected. Patients were grouped according to the presence of VAP. The correlation between α-amylase and risk factors of aspiration before intubation, as well as VAP, were analyzed. The sample of this study comprised 147 patients. The average age of these patients was 86.9 years. The incidence of VAP was 21% during the study period. Tracheal aspirate α-amylase level increased with the increase in the number of risk factors for aspiration before intubation, α-amylase level was significantly higher in the VAP group than in the non-VAP group, the area under the receiver operating characteristic curve (ROC) of the diagnostic value of α-amylase for VAP was 0.813 (95% CI: 0.721-0.896), threshold value was 4,681.5 U/L, sensitivity was 0.801 and specificity was 0.793. Logistic multivariate analysis revealed the following risk factors for VAP: a number of risk factors before intubation of ≥3, a Glasgow score of aspiration of subglottic secretion and a tracheal aspirate α-amylase level of >4681.5 U/L. Tracheal aspirate α-amylase can serve as a biomarker for predicting VAP in elderly patients undergoing mechanical ventilation. © 2017 John Wiley & Sons Ltd.

Endometrial evaluation is generally indicated in cases presenting with abnormal uterine bleeding (AUB), especially in women more than 35 years of age. AUB encompasses a variety of presentation, for example, heavy menstrual bleeding, frequent bleeding, irregular vaginal bleeding, postcoital and postmenopausal bleeding to name a few. Many methods are used for the evaluation of such cases, with most common being sonography and endometrial biopsy with very few cases requiring more invasive approach like hysteroscopy. Endometrial aspiration is a simple and safe office procedure used for this purpose. We retrospectively analyzed cases of AUB where endometrial aspiration with Pipette (Medgyn) was done in outpatient department between January 2015 and April 2016. Case records (both paper and electronic) were used to retrieve data. One hundred and fifteen cases were included in the study after applying inclusion and exclusion criteria. Most cases were between 46 and 50 years of age followed by 41-45 years. No cases were below 25 or more than 65 years of age. Heavy menstrual bleeding was the most common presentation of AUB. Adequate samples were obtained in 86% of cases while 13.9% of cases' sample was inadequate for opinion, many of which were later underwent hysteroscopy and/or dilatation and curettage (D and C) in operation theater; atrophic endometrium was the most common cause for inadequate sample. Uterine malignancy was diagnosed in three cases. Endometrial aspiration has been compared with traditional D and C as well as postoperative histopathology in various studies with good results. Many such studies are done in India as well as in western countries confirming good correlation with histopathology and adequate tissue sample for the pathologist to give a confident diagnosis. No complication or side effect was noted with the use of this device. Endometrial aspiration is a simple, safe, and effective method to sample endometrium in cases of AUB avoiding risk of

Should fine needle aspiration cytology in breast assessment be abandoned?

International Nuclear Information System (INIS)

Litherland, Janet C.

2002-01-01

Fine needle aspiration cytology (FNAC) has been used extensively in the U.K. for the diagnosis of breast lesions over the past 15 years. More recently, large gauge needle biopsy has been used to address many of the problems which have been encountered with fine needle aspiration. This paper reviews the evolution of the use of these procedures and the advantages and disadvantages of each. In considering whether to abandon the use of fine needle aspiration cytology in breast assessment, each individual unit should make a decision based upon their own audited results. However, even if FNAC is retained, it is important to be able to complement cytological diagnosis with core biopsy as there are indisputable advantages, e.g. in the diagnosis of mammographically detected microcalcification. As always, a multi-disciplinary approach is ultimately essential for effective patient management. Litherland, J.C. (2002)

Nodular thyroid disease is one of the most frequently diagnosed pathologies of the adult population in iodine-deficient regions. Approximately 30% of thyroid aspirates are classified as nondiagnostic/unsatisfactory or indeterminate. However, patients with indeterminate cytology still undergo surgery. The object of this study was to determine the diagnostic value of re-examining the BRAF V600E mutation in papillary thyroid carcinoma patients. All patients underwent ultrasound guided fine-needle aspiration of a thyroid nodule. They were assigned to one of the four groups (indeterminate or positive for malignant cells) of the Bethesda System for Reporting Thyroid Cytopathology. Genetic investigation of the BRAF V600E mutation was performed for all of the fine-needle aspiration cytology specimens. All of the patients underwent surgery. Subsequently, histological investigation of the removed tissues was performed. Additional analysis of the BRAF V600E mutation from the histology specimen was then performed for the initially BRAF-negative cases. Two hundred and fourteen patients were involved in the study. One hundred and six (49.53%) patients were diagnosed with thyroid cancer. Of these 106 patients, 95 (89.62%) patients were diagnosed with papillary thyroid cancer. The BRAF V600E mutation was positive in 62 (65.26%) and negative in 33 (34.74%) histologically confirmed papillary thyroid cancer cases. After the genetic investigation, a total of 74 (77.89%) papillary thyroid cancer cases were positive for the BRAF V600E mutation and 21 (22.11%) were negative. Repeated examination of the BRAF V600E mutation status in the fine-needle aspiration may potentially increase the sensitivity of papillary thyroid cancer diagnostics.

Intractable aspiration is a serious, often life-threatening condition due to its potential impact on pulmonary function. Aspiration requires therapeutic measures, starting with conservative management but often necessitating surgical treatment. The basic surgical principle is to separate the alimentary and respiratory tracts through a variety of procedures which, unfortunately, nearly all result in the loss of phonation, with the exception of total laryngectomy (TL) which includes the placement of an indwelling voice prosthesis. In this study, we present a modified laryngotracheal separation (LTS) technique that, we believe, offers multiple advantages compared to standard TL. After reviewing the medical records of 35 patients with intractable aspiration who have undergone LTS, we describe the surgical technique and present the postoperative result. In a second surgical procedure about two months following LTS, we aimed to achieve voice restoration by placement of an indwelling voice prosthesis. Intractable aspiration was successfully treated in all patients. Placement of an indwelling voice prosthesis during a second operation was successful in 15 patients, representing the largest reported cohort thus far. LTS is a reliable surgical technique to treat intractable aspiration, with restoration of oral intake, thereby improving the general condition and quality of life of these unfortunate patients. Furthermore, voice restoration can be achieved in selected patients, by placement of a voice prosthesis.

[Tracheobronchial lavage--a supplementary measure in the initial management of meconium aspiration syndrome].

Pulmonary lavage - a supplementary measure of resuscitation in newborn infants with severe aspiration of meconium stained amniotic fluid. During 1984-1985 150 mature newborn infants who had aspirated heavily-stained or pea soup-like amniotic fluid were resuscitated at the University Hospital of Obstetrics and Gynaecology in Graz. In 109 of these infants (controls) routine aspiration of both the upper and lower airways was accomplished as soon as possible, whilst in the remaining 41 infants (lavaged) pulmonary lavage with saline was additionally performed via an endotracheal tube after aspiration to clear the trachea and the upper bronchi from thick meconium which could not have been removed as efficiently otherwise. The incidence of manifest meconium aspiration syndrome was significantly higher (22%) in the lavaged infants than in the controls (8%). Mechanical ventilation was performed in 36% of the lavaged infants, whereas only 5.5% of the controls had to be ventilated for more than 1 hour. The mean duration of ventilation, however, was shorter (Mh = 5.1 hrs vs Mh = 69 hrs) and the average age at discharge lower in the lavaged. Three infants died, two of whom had severe malformations. Only one death in the lavaged infants was attributable to severe meconium aspiration syndrome already manifest at birth. Three infants (two lavaged, one control) showed radiological evidence of pneumothorax, but without clinical appearance of respiratory distress. Since the lavaged group naturally contained the more severely distressed infants, with a high incidence of caesarean section on account of intrauterine asphyxia and lower Apgar scores at one and five minutes, the high incidence of radiologically confirmed meconium aspiration syndrome was not surprising.(ABSTRACT TRUNCATED AT 250 WORDS)

To analyse the cytomorphologic spectrum of Wilms tumour (WT) on aspirates, the largest series reported to date. Adequate aspirates from paediatric renal tumours over a period of 17 years were reviewed and selected if subsequent excision showed WT or aspirates were diagnostic for WT and clinical/radiological evidence consistent with that diagnosis. Smears were re-examined for the proportion of components, degree of pleomorphism and mitosis. Of 110 aspirates, smears were triphasic in 44 (40.0%), biphasic (blastema and tubules) in 36 (32.7%) and monophasic (blastema alone) in 30 (27.3%). Stromal predominance was seen in 11 aspirates (10.0%) and five showed rhabdomyoblastic differentiation; all 11 were triphasic. Mean mitotic rate was 9.3/5000 cells (range 4-39/5000). Nuclear atypia not amounting to anaplasia and without atypical mitoses was seen in 15 (13.6%); these presented diagnostic problems. Two aspirates (1.8%) were considered anaplastic (unfavourable), both having atypical mitoses. Criteria similar to histology (i.e. 3-fold or more variation in nuclear size, marked hyperchromasia with bizarre nuclei and atypical mitoses in a biphasic or triphasic aspirate) helped in distinguishing anaplastic WT. Histopathological correlation in 67 cases showed good correlation of blastemal predominance, stromal predominance and anaplastic histology with the corresponding cytology. However, 9/27 (33.3%) triphasic tumours had only blastemal cells on corresponding aspiration because of sampling error. Cytokeratin was positive in 4 of 20 aspirates with blastema alone. Aspirates from WT were triphasic or biphasic in the majority (72.7%), permitting cytological diagnosis, which was improved by cytokeratin immunocytochemistry. Blastemal and stromal predominance on histology correlated well with cytology, but many triphasic tumours showed only blastema on aspiration. Anaplastic WT can be detected on aspirates using criteria similar to histology. © 2010 Blackwell Publishing Ltd.

Full Text Available Introduction and aim: The video-urodynamics study is the principal exam to establish a possible primary bladder neck obstruction (PBNO condition. While trans-rectal ultrasonography plays an important role in the evaluation of the low urinary tract symptoms (LUTS and the severity of bladder outlet obstruction (BOO in men, the use of the transvaginal ultrasound (TVUS in women with symptoms suggesting BOO remains unclear. We tried to check the utility of the TVUS in women with PBNO condition. Material and methods: We selected female patients which presented BOO without pelvic organ prolapse (POP. According to the data of the video-urodynamic exam we selected the patients with the suspicion of PBNO. A TVUS in basal and during micturition was performed before and after surgery. Results: TVUS showed a closed bladder neck bladder in basal condition and during micturition similarly to the fluoroscopic image during video-urodynamics. The mean distance from bladder neck to the vaginal mucosa resulted 1.3 cm in this patients. Conclusions: TVUS results worthy in the evaluation of patients with PBNO before and after surgery.

How to exploit public non-renewable resources is a public goods dilemma. Individuals can choose to limit the depletion in order to use the resource for a longer time or consume more goods to benefit themselves. When the resource is used up, there is no benefit for the future generations any more, thus the evolutionary process ends. Here we investigate what mechanisms can extend the use of resources in the framework of evolutionary game theory under two updating rules based on imitation and aspiration, respectively. Compared with imitation process, aspiration dynamics may prolong the sustainable time of a public resource. - Highlights: • We establish a game model to capture the sustainable time of public goods. • We propose a theoretical method to study how fast an evolutionary process ends. • Strong selection shortens the evolutionary time of public resource dilemma. • Compared with imitation process, aspiration dynamics prolong the sustainable time. • The sustainable time is the shortest for the intermediate aspiration level.

Compared with imitation process, aspiration dynamics may prolong the sustainable time of a public resource. - Highlights: • We establish a game model to capture the sustainable time of public goods. • We propose a theoretical method to study how fast an evolutionary process ends. • Strong selection shortens the evolutionary time of public resource dilemma. • Compared with imitation process, aspiration dynamics prolong the sustainable time. • The sustainable time is the shortest for the intermediate aspiration level.

Objective Determine if race or ethnicity is associated with missed or late transvaginal cervical length screening in a universal screening program. Methods Retrospective cohort study of nulliparous women with singleton gestations and a fetal anatomical ultrasound from 16-24 weeks' gestation from January, 2012 through November, 2013. We classified women into mutually exclusive racial and ethnic groups: non-Hispanic black (black), Hispanic, Asian, non-Hispanic white (white), and other or unknown race. We used log-binomial regression to calculate the risk ratio (RR) and 95% confidence interval (CI) of missed or late (≥ 20 weeks' gestation) screening vs. optimally-timed screening between the different racial and ethnic groups. Results Among the 2 967 women in our study population, 971 (32.7%) had either missed or late cervical length screening. Compared to white women, black (RR: 1.3; 95% CI:1.1-1.5) and Hispanic (RR:1.2; 95% CI:1.01-1.5) women were more likely to have missed or late screening. Among women screened, black (vs. white) women were more likely to be screened late (RR: 2.2; 95% CI: 1.6-3.1). Conclusions Black and Hispanic women may be more likely to have missed or late cervical length screenings. PMID:26987873

Fluid samples obtained from an affected joint still play a central role in the diagnosis of periprosthetic joint infection (PJI). It is the only preoperative test able to discover the causative microbiological agent. In the hip, fluid aspiration can be performed through fluoroscopy, ultrasound, or, less commonly, computed tomography. However, there is still a lack of consensus on which method is preferable in terms of efficacy and costbenefit. We, therefore, asked whether (1) the benefits in terms of sensitivity and specificity and (2) the costs were comparable between fluoroscopy- and ultrasound-guided joint aspirations in a suspicious of hip PJI. Between 2013 and 2016, 52 hip aspirations were performed on 49 patients with clinical, radiological, or serological suspicion of PJI, waiting for a revision surgery. The patients were divided in two groups: fluoroscopy- (n = 26) vs ultrasound-guided hip aspiration group (n = 26). These groups were also divided in control and infected patients. The criteria of MusculoSkeletal Infection Society (MSIS) were used, as gold standard, to define PJI. (1) Ultrasound-guided aspiration revealed valid sensitivity (89% vs 60%) and specificity (94% vs 81%) in comparison with fluoroscopic-guided aspiration. (2) The cost analysis was also in favor of ultrasound-guided aspiration (125.30€) than fluoroscopic-guided aspiration (343.58€). We concluded that ultrasound-guided hip aspiration could represent a valid, safe, and less expensive diagnostic alternative to fluoroscopic-guided aspiration in hip PJI.

Although women who highly identify with other women are more susceptible to stereotype threat effects, women's identification might associate with greater leadership aspirations contingent on (1) counter-stereotype salience and (2) feminist identification. When gender counter-stereotypes are salient, women's identification should associate with greater leadership aspiration regardless of feminism, while when gender stereotypes are salient, women's identification would predict greater leadersh...

Recently, CT-guided stereotactic aspiration has been attempted as a useful method for hypertensive intracerebral hemorrhage. Since the CT scanner was introduced in our clinic, we have experienced 55 cases with hypertensive pontine hemorrhage. We carried out stereotactic aspiration in nine cases consisting of four men and five women, ranging in age from 34 to 66 years. Operation was performed between 4 and 22 days after the hemorrhage (mean: 7.7 days). On the other hand, 46 cases were conservatively treated. They consisted of 31 men and 15 women, aged from 31 to 79 years, with a mean age of 55.5 years. The purpose of this study is to review the outcome at three months after the onset, and then to evaluate the clinical value of this method for hypertensive pontine hemorrhage. We have analyzed the outcome from the viewpoint of consciousness level, CT classification, and maximum transverse hematoma diameter on CT scan. In the present study, there was a statistically significant correlation between consciousness level and outcome in the conservative group. The outcome in the operated-on group tended to be superior to that in the conservatively treated group. Particularly, in cases of Japan Coma Scale 10 to 100, functionally favorable effects were considered to be obtained by stereotactic aspiration. According to CT classification, operation was considered to have exerted functionally favorable effects on unilateral basis tegmentum type and bilateral tegmentum type. The conservatively treated group showed a statistically significant correlation between maximum transverse hematoma diameter and outcome. A favorable prognosis was considered to be induced by operation in cases of 22 to 28 mm in maximum transverse hematoma diameter. (author)

BACKGROUND The aim of this study was to evaluate the curative effect of transvaginal mesh repair (TVMR) and stapled transanal rectal resection (STARR) in treating outlet obstruction constipation caused by rectocele. MATERIAL AND METHODS Patients who had outlet obstruction constipation caused by rectocele were retrospectively analyzed and 39 patients were enrolled the study. Patients were assigned to either the TVMR or STARR group. Postoperative factors such as complications, pain, recurrence rate, and operative time were compared between the 2 groups. RESULTS Total effective rate was 100% in both groups. No long-term chronic pain occurred and discomfort rate of tenesmus was higher in the STARR group than in the TVMR group. Postoperative defecography showed that the rectocele depth was significantly reduced, and the prolapse of the rectal mucosa and the lower rectal capacity was also decreased. Four cases had mesh exposure in the TVMR group and 2 cases in the STARR group had anastomotic bleeding after the surgery. CONCLUSIONS For outlet obstruction constipation caused by rectocele, TVMR and STARR both obtained satisfactory results. Although TVMR is complex with longer operative time and hospitalization period, its long-term effect is better than that of STARR.

Full Text Available This paper aims to classify career aspirations by identifying career anchors and self-monitoring for a second-year undergraduates studying at two top of range universities in St. Petersburg. The participants major in strategical professions. The study involved 202 people from the following bachelor programs: «Logistics and Supply chain management» (n=98, «Sociology» (n=92 and «Human Resource Management» (n=22. The findings illustrate that peculiarities of undergraduates’ career aspirations are possible to estimate using career anchors developed by Schein and level of self-monitoring developed by Snyder which are varied for students studying at different educational programs. The results also indicate the significant differences of career aspirations between young girls and young men at each bachelor’s program. The male groups, having the same level of self-monitoring with female ones, demonstrate some differences in career anchors.

Aspiration of barium sulfate occurs accidentally. Lung reaction is usually mild in the early phase due to inert character of the substance and long-term reactions or late toxicities are not expected. Little if any fibrotic response is speculated. We present a case with barium aspiration, studied by high-resolution computed tomography (HRCT) 1 year after the event, as late pulmonary sequelae studied by CT have not been described yet, to the best of our knowledge. The HRCT revealed thickened interlobular septa, subpleural lines, subpleural cysts, and centrilobular micronodules along with barium particles in a subpleural distribution. Those findings indicated that barium is capable of producing mild though silent clinically fibrosis. (orig.)

Cross-Modal Correspondence between Brightness and Chinese Speech Sound with Aspiration

Directory of Open Access Journals (Sweden)

Sachiko Hirata

2011-10-01

Full Text Available Phonetic symbolism is the phenomenon of speech sounds evoking images based on sensory experiences; it is often discussed with cross-modal correspondence. By using Garner's task, Hirata, Kita, and Ukita (2009 showed the cross-modal congruence between brightness and voiced/voiceless consonants in Japanese speech sound, which is known as phonetic symbolism. In the present study, we examined the effect of the meaning of mimetics (lexical words whose sound reflects its meaning, like “ding-dong” in Japanese language on the cross-modal correspondence. We conducted an experiment with Chinese speech sounds with or without aspiration using Chinese people. Chinese vocabulary also contains mimetics but the existence of aspiration doesn't relate to the meaning of Chinese mimetics. As a result, Chinese speech sounds with aspiration, which resemble voiceless consonants, were matched with white color, whereas those without aspiration were matched with black. This result is identical to its pattern in Japanese people and consequently suggests that cross-modal correspondence occurs without the effect of the meaning of mimetics. The problem that whether these cross-modal correspondences are purely based on physical properties of speech sound or affected from phonetic properties remains for further study.

Evidence for the effect of granulocyte colony stimulating factor (G-CSF) on infertile women undergoing in vitro fertilization (IVF) remains inconsistent. This study aimed to evaluate the effectiveness of G-CSF on infertile women undergoing IVF. PubMed and EMBASE databases were searched before August 2016. Comparing the transvaginal perfusion of G-CSF and placebo or no treatment, the available studies were considered. The pooled risk ratio (RR) with 95% confidence intervals (CIs) was used in the analysis and six studies were included. Transvaginal perfusion of G-CSF was significantly associated with a higher clinical pregnancy rate versus the placebo (RR=1.563, 95%CI: 1.122, 2.176), especially for the Asian population. Among patients with a thin endometrium or repeated IVF failure, the implantation and biochemical pregnancy rates were also significantly increased in patients with the use of G-CSF (implantation rate: RR = 1.887, 95% CI: 1.256, 2.833; biochemical pregnancy rate: RR = 2.385, 95% CI: 1.414, 4.023). However, no statistical significance in increasing endometrial thickness was detected. Transvaginal perfusion of G-CSF for infertile women may play a critical role in assisting human reproduction, especially for patients with a thin endometrium or repeated IVF failure in the Asian population.

To evaluate the long term efficacy and safety of transvaginal implantation of a non-resorbable synthetic prosthesis (Gynemesh) for the treatment of cystocele using transvaginal free tension technique. Prospective study of patients that have been submitted to correction of cystocele between April 2004 and July 2007. A prolene mesh was cut to an appropriate size to cover the whole cystocele leaving two tabs on each side. The two tabs of the mesh were then placed in paravaginal spaces, tension free, without stitches. Mesh was used in 31 patients. All patients had a symptomatic cystocele >or= 2 according to Baden-Walker halfway classification. Patients were reviewed initially at 1 and 3 month and then every 6 months. The mean age of the patients was 58 years (range: 47-70 years). Mean parity was 5.8 (range 1-11), and mean weight was 75 kg (range 60-82Kg). All women were postmenopausal. The operation was combined with vaginal hysterectomy in 2 patients, Posterior colporraphy in 2 patients, Perineorrhaphy in 1 patient, Sacrospinous fixation in 2 patients, transobturator tape for stress urinary incontinence in 7 women. Average time of surgery was 23 minutes for cystocele. There were no major complications, such as trauma to the bladder, urethra, bowels, or large vessels in the patient group treated. There was no immediate postoperative complications (up to 7 days) recorded. No hematoma or infection was observed in the operative area. Mesh erosion was detected in one patient. It was treated by excision of the eroded part of the mesh. Mean follow-up was 36.4 months (18 to 52 months). Using our definition of success based on both anatomic and functional outcomes, the overall cure rate was 74.19% (asymptomatic with no or grade 1 cystocele). The improvement rate (asymptomatic with a grade 2 cystocele) was 19.35% and the overall failure rate (symptomatic or with a grade 3 or 4 cystocele) was only 6.4% (2 women).

We have studied whether hyperbaric oxygen (HBO) prevents different pulmonary aspiration materials-induced lung injury in rats. The experiments were designed in 60 Sprague-Dawley rats, ranging in weight from 250 to 300 g, randomly allotted into one of six groups (n = 10): saline control, Biosorb Energy Plus (BIO), hydrochloric acid (HCl), saline + HBO treated, BIO + HBO treated, and HCl + HBO treated. Saline, BIO, HCl were injected into the lungs in a volume of 2 ml/kg. A total of seven HBO sessions were performed at 2,4 atm 100% oxygen for 90 min at 6-h intervals. Seven days later, rats were sacrificed, and both lungs in all groups were examined biochemically and histopathologically. Our findings show that HBO inhibits the inflammatory response reducing significantly (P fibrosis, granuloma, and necrosis formation in different pulmonary aspiration models. Pulmonar aspiration significantly increased the tissue HP content, malondialdehyde (MDA) levels and decreased (P < 0.05) the antioxidant enzyme (SOD, GSH-Px) activities. HBO treatment significantly (P < 0.05) decreased the elevated tissue HP content, and MDA levels and prevented inhibition of SOD, and GSH-Px (P < 0.05) enzymes in the tissues. Furthermore, there is a significant reduction in the activity of inducible nitric oxide synthase, TUNEL and arise in the expression of surfactant protein D in lung tissue of different pulmonary aspiration models with HBO therapy. It was concluded that HBO treatment might be beneficial in lung injury, therefore, shows potential for clinical use.

Mesh-related complications following transvaginal management of pelvic organ prolapse (POP) and/or stress urinary incontinence (SUI) have received significant attention in the last decade. We sought to identify patient, product, and technical factors associated with an increased risk of complications after mesh-based transvaginal repair of anterior POP and SUI. In this review we clarify the different pattern of complications after POP and SUI repairs. Our aim is to provide a practical evidence-based guide for physicians to prevent and, if necessary, manage product-associated complications in a stepwise manner. We conducted a comprehensive PubMed search of all English-language articles published from 2010 to June 2016, using these search terms: mesh, pelvic organ prolapse, and stress urinary incontinence. Expert opinion is also provided. Mesh-related complications are much lower after repair of SUI compared with POP, despite its more frequent use. Vaginal exposure is the most common mesh-specific complication. Patients may present with vaginal discharge, dyspareunia, pain, recurrent urinary tract infection, and/or hematuria. Conversely, patients may be asymptomatic. Small asymptomatic mesh exposures (mesh encountered within the urinary tract must be fully excised. Following excision, pain may persist in up to 50% of patients. Vaginal extrusion, persistent pain, and urethral and/or bladder erosion are the three most common product-specific complications following mesh-based repair for SUI or POP. Conservative therapies may be attempted, but most patients ultimately require partial or complete mesh excision. We reviewed the recent literature on mesh-related complications after repair of pelvic organ prolapse (POP) and stress urinary incontinence (SUI). Vaginal exposure, persistent pain, and erosion into the urinary tract are the most common. These often require surgical management, best suited to a urologist with training and experience in this area. Evidence supports

Natural Orifice Transluminal Endoscopic Surgery (NOTES) provides an emerging surgical technique which usually needs a long learning curve for surgeons. Virtual reality (VR) medical simulators with vision and haptic feedback can usually offer an efficient and cost-effective alternative without risk to the traditional training approaches. Under this motivation, we developed the first virtual reality simulator for transvaginal cholecystectomy in NOTES (VTEST™). This VR-based surgical simulator aims to simulate the hybrid NOTES of cholecystectomy. We use a 6DOF haptic device and a tracking sensor to construct the core hardware component of simulator. For software, an innovative approach based on the inner-spheres is presented to deform the organs in real time. To handle the frequent collision between soft tissue and surgical instruments, an adaptive collision detection method based on GPU is designed and implemented. To give a realistic visual performance of gallbladder fat tissue removal by cautery hook, a multi-layer hexahedral model is presented to simulate the electric dissection of fat tissue. From the experimental results, trainees can operate in real time with high degree of stability and fidelity. A preliminary study was also performed to evaluate the realism and the usefulness of this hybrid NOTES simulator. This prototyped simulation system has been verified by surgeons through a pilot study. Some items of its visual performance and the utility were rated fairly high by the participants during testing. It exhibits the potential to improve the surgical skills of trainee and effectively shorten their learning curve. Copyright © 2016 Elsevier Inc. All rights reserved.

Purpose of the present study is to evaluate lung impairment in an acute aspiration model by using new CT method and to assess the application of the method for clinical cases. Subjects in experimental model were anesthetized and mechanically ventilated beagle dogs (n=5), and subjects in clinical cases were patients with aspiration in acute phase (n=5). For the preparation of the acute aspiration model, 2% Gastrografin (diatrizoate megulumine) aqueous solution was instilled cumulatively (0.1-3.0 ml/kg) into the right main bronchus through the endobronchial tube. Two methods of CT scan, Spirometric gating CT (SGCT) and Dynamic CT, were performed before and after instillation. SGCT can adjust the pulmonary volume at each scan by built-in spirometer. Three-dimensional reconstruction of the whole lung image was obtained with scan data by SGCT. Dynamic CT method was utilized for assessment of the ventilation dynamics. Continuous scan of the lung at the carina level was performed during ventilation and time-series image data were obtained at a rate of 5 frames/sec. The CT densitometry of the Dynamic CT images were carried out and time-attenuation curves with ventilation were analyzed. In experimental model, the whole lung images by SGCT after instillation showed invasion of Gastrografin into right lower lobe and the compensatory overinflation in the other lobes. The time-attenuation curves by Dynamic CT showed that both the mean and amplitude of the attenuation increased in the right lower lobe where the Gastrografin instilled. But the amplitude decreased when the mean value showed no apparent change at the first period of instillation. In acute phase of the aspiration, the amplitude will be the sensitive index of the ventilation impairment. In clinical case subjects were scanned during spontaneous breathing by Dynamic CT. Both the mean and amplitude of the attenuation of the time-increased when the aspiration occurred. After four days passed, the mean value increased

Guidelines for providing privileges and credentials to physicians for transvaginal placement of surgical mesh for pelvic organ prolapse.

Science.gov (United States)

2012-01-01

The adoption of new technology or procedures into a clinician's surgical armamentarium is driven by multiple factors. Patient safety and anticipated long-term improvement in outcomes should be the primary objective that guides a surgeon's decision to deliver care involving new procedures. Surgically complex procedures require a balance of knowledge, surgical skill, and experience, with appropriate ongoing surgical volume and monitoring of outcomes and adverse events. Transvaginal placement of surgical mesh for pelvic organ prolapse has the potential to improve quality of life and anatomic outcomes (especially in the anterior compartment), but also has potential serious adverse events as outlined by the FDA's July 2011 Safety Communication. This document provides Guidelines for privileging and credentialing of physicians planning to implement or continue using this new technology in clinical practice.

Primary fallopian tube carcinoma is a rare malignancy and is not often diagnosed preoperatively. We present a case of a 67-year-old woman who complained of postmenopausal vaginal bleeding. After a negative hysteroscopy, transvaginal ultrasound showed a well vascularized solid-cystic tumor in the adnexal region separate from the ovary. The presence of an adnexal mass was confirmed by MR imaging. Total abdominal hysterectomy with bilateral salpingoophorectomy, omentectomy and appendectomy, as well as pelvic and paraaortic lymphadenectomy was performed. The pathohistological diagnosis was poorly differentiated serous adenocarcinoma of the fallopian tube, FIGO stage IA. The patient was subsequently treated with platinum based adjuvant chemotherapy.

A radial basis classifier for the automatic detection of aspiration in children with dysphagia

Full Text Available Abstract Background Silent aspiration or the inhalation of foodstuffs without overt physiological signs presents a serious health issue for children with dysphagia. To date, there are no reliable means of detecting aspiration in the home or community. An assistive technology that performs in these environments could inform caregivers of adverse events and potentially reduce the morbidity and anxiety of the feeding experience for the child and caregiver, respectively. This paper proposes a classifier for automatic classification of aspiration and swallow vibration signals non-invasively recorded on the neck of children with dysphagia. Methods Vibration signals associated with safe swallows and aspirations, both identified via videofluoroscopy, were collected from over 100 children with neurologically-based dysphagia using a single-axis accelerometer. Five potentially discriminatory mathematical features were extracted from the accelerometry signals. All possible combinations of the five features were investigated in the design of radial basis function classifiers. Performance of different classifiers was compared and the best feature sets were identified. Results Optimal feature combinations for two, three and four features resulted in statistically comparable adjusted accuracies with a radial basis classifier. In particular, the feature pairing of dispersion ratio and normality achieved an adjusted accuracy of 79.8 ± 7.3%, a sensitivity of 79.4 ± 11.7% and specificity of 80.3 ± 12.8% for aspiration detection. Addition of a third feature, namely energy, increased adjusted accuracy to 81.3 ± 8.5% but the change was not statistically significant. A closer look at normality and dispersion ratio features suggest leptokurticity and the frequency and magnitude of atypical values as distinguishing characteristics between swallows and aspirations. The achieved accuracies are 30% higher than those reported for bedside cervical auscultation. Conclusion

Directory of Open Access Journals (Sweden)

Jason M. Sandberg

2018-03-01

Full Text Available Purpose: To assess the utility of the Manufacturer And User Facility Device Experience (MAUDE database in objectively capturing adverse events for transvaginal mesh in the United States. Materials and Methods: We reviewed 1,103 individual medical device reports submitted to the MAUDE database that inspired the United States (US Food and Drug Administration's 2008 Public Health Notification. Entries were compiled into a categorical database that reported manufacturer, brand, reporter type, report source, and type of adverse event. Results: There were numerous examples of missing, duplicated, and non-standardized entries. Analysis revealed 64 reports with duplicated information, and six reports representing multiple patients. Forty-seven percent of medical device reports did not identify a reporter source. At least 28% of reported devices are no longer on the US market. There was wide variability in the quality and completeness of submitted reports and true adverse event rates could not be accurately calculated because the number of total cases was unknown. Conclusions: The MAUDE database was limited in its ability to collect, quantify, and standardize real-life adverse events related to transvaginal mesh. While it functions to collect information related to isolated adverse events, systematic limitations of the MAUDE database, that no doubt extend to other medical devices, necessitate the development of new reporting systems. Alternatives are under development, which may allow regulators to more accurately scrutinize the safety profiles of specific medical devices.

Capillary Versus Aspiration Biopsy: Effect of Needle Size and Length on the Cytopathological Specimen Quality

International Nuclear Information System (INIS)

Hopper, Kenneth D.; Grenko, Ronald T.; Fisher, Alicia I.; TenHave, Thomas R.

1996-01-01

Purpose: To test the value of the nonaspiration, or capillary, biopsy technique by experimental comparison with the conventional fine-needle aspiration technique using various needle gauges and lengths. Methods: On fresh hepatic and renal tissue from five autopsies, multiple biopsy specimens were taken with 20, 22, and 23-gauge Chiba needles of 5, 10, 15, and 20-cm length, using the aspiration technique and the capillary technique. The resultant specimens were graded on the basis of a grading scheme by a cytopathologist who was blinded to the biopsy technique. Results: The capillary technique obtained less background blood or clot which could obscure diagnostic tissue, although not significantly different from the aspiration technique (p= 0.2). However, for the amount of cellular material obtained, retention of appropriate architecture, and mean score, the capillary technique performed statistically worse than aspiration biopsy (p < 0.01). In addition, with decreasing needle caliber (increasing needle gauge) and increasing length, the capillary biopsy was inferior to the aspiration biopsy. Conclusion: The capillary biopsy technique is inferior to the aspiration technique according to our study. When the capillary technique is to be applied, preference should be given to larger caliber, shorter needles

Pulmonary aspiration was assessed using a scintigraphic swallowing procedure in 14 dysphagics in whom penetration of the larynx had been previously diagnosed. No patient had recent evidence of aspiration pneumonia. Imaging was performed during and following ingestion of a cupful of thin liquid admixed with between 1-2 mCi of Tc-99m sulfur colloid. Follow-up scans were obtained several hours later as needed to assess airway clearance. Five of the fourteen (36%) showed penetration distal to the trachea. Seven (50%) were indeterminate for aspiration, as isotope localized to the neck could not be clearly designated as being in either airway or foodway. Two subjects had negative studies. Of patients with subtracheal penetration, (1) fractions of the ingested material which were aspirated ranged from restriction at the time of testing were allowed to ease restrictions. Five patients without prior liquid restriction were allowed to continue to drink. We propose that scintigraphy provides important data on airway penetration and clearance that is useful in the dietary management of dysphagic patients.

Abnormal Uterine Bleeding- evaluation by Endometrial Aspiration

Directory of Open Access Journals (Sweden)

Pratibha Singh

2018-01-01

Full Text Available Endometrial evaluation is generally indicated in cases presenting with abnormal uterine bleeding (AUB, especially in women more than 35 years of age. AUB encompasses a variety of presentation, for example, heavy menstrual bleeding, frequent bleeding, irregular vaginal bleeding, postcoital and postmenopausal bleeding to name a few. Many methods are used for the evaluation of such cases, with most common being sonography and endometrial biopsy with very few cases requiring more invasive approach like hysteroscopy. Endometrial aspiration is a simple and safe office procedure used for this purpose. Materials and Methods: We retrospectively analyzed cases of AUB where endometrial aspiration with Pipette (Medgyn was done in outpatient department between January 2015 and April 2016. Case records (both paper and electronic were used to retrieve data. Results: One hundred and fifteen cases were included in the study after applying inclusion and exclusion criteria. Most cases were between 46 and 50 years of age followed by 41–45 years. No cases were below 25 or more than 65 years of age. Heavy menstrual bleeding was the most common presentation of AUB. Adequate samples were obtained in 86% of cases while 13.9% of cases' sample was inadequate for opinion, many of which were later underwent hysteroscopy and/or dilatation and curettage (D and C in operation theater; atrophic endometrium was the most common cause for inadequate sample. Uterine malignancy was diagnosed in three cases. Discussion: Endometrial aspiration has been compared with traditional D and C as well as postoperative histopathology in various studies with good results. Many such studies are done in India as well as in western countries confirming good correlation with histopathology and adequate tissue sample for the pathologist to give a confident diagnosis. No complication or side effect was noted with the use of this device. Conclusion: Endometrial aspiration is a simple, safe, and

Landscapes of Aspiration in Guangzhou’s African Music Scene: Beyond the Trading Narrative

Directory of Open Access Journals (Sweden)

Roberto Castillo

2015-01-01

Full Text Available This article is an exploration into the personal aspirations that converge in Guangzhou’s African music scene. I argue that despite being often traversed, articulated, fuelled, and constrained by economies and economic discourses, aspirations are not necessarily economic or rational calculations. I contend that the overarching trading narrative about “Africans in Guangzhou” has left little space for issues of agency, emotion, and aspiration to be considered in their own right. Drawing on a year of continuous ethnographic fieldwork, I show how aspirations are crucial arenas where the rationales behind transnational mobility are developed, reproduced, and transmitted. Indeed, aspirations can be thought of as “navigational devices” (Appadurai 2004 that help certain individuals reach for their dreams. By bringing the analysis of aspirations to the fore, I intend to provide a more complex and nuanced landscape of the multiple rationales behind African presence in Southern China; promote a better understanding (both conceptually and empirically of how individuals navigate their social spaces and guide their transnational journeys; and draw attention to the incessant frictions and negotiations between individual aspirations while on the move and the constraints imposed by more structural imperatives.

To assess ultrasonographically (US) guided needle aspiration of breast abscesses as an alternative to surgical incision and drainage. In our prospective study, 30 patients with 31 breast abscesses (one patient had bilateral breast abscess) underwent percutaneous breast abscess drainage under US guidance with local anaesthesia and oral antibiotics between 1 January 2004 and 31 March 2005. These patients consisted of 16 (53.3%) non-lactating and 14 (46.7%) lactating women, with ages ranging from 18 to 68 years (median, 28 years). The racial distribution comprised 26 (86.7%) Malays, three (10%) Chinese and one (3.3%) Indian. All patients had the chief complaint of breast swelling and 25 (83.3%) had breast pain. Clinically, 28 (93.3%) were found to have a palpable mass. Nine (30%) lesions were in the upper outer quadrant of the left breast. US diameters ranged from 1 to 15 cm (median, 4 cm). The pus volumes varied from 1 to 200 mL (median, 14 mL). Fifteen (50%) patients required only a single aspiration, 10 required multiple aspirations and five required incision and drainage. Those patients in whom needle aspiration failed had multiloculated lesions irrespective of abscess volume and size. Needle aspiration with ultrasound guidance is an effective treatment for breast abscess irrespective of abscess volume and size.

To establish predictive models for late objective aspiration and late patient-reported choking based on dose-volume parameters and baseline patient and treatment characteristics, for patients with head and neck cancer undergoing definitive radiotherapy (RT). The impact of electively treated volume on late aspiration was also investigated. This prospective cohort is a subsample of 124 survivors from the ARTSCAN study. Late aspiration was identified with videofluoroscopy, at a minimum of 25months after the start of RT. Patient-reported choking was analysed at 12 and 60months post RT using the EORTC Quality of Life Module for Head and Neck Cancer 35. Univariable and multivariable analyses were performed to describe the association between clinical factors and dose-volume descriptors for organs at risk (OARs) and late dysphagia. Aspiration was found in 47% of the eligible patients. Mean dose to the middle pharyngeal constrictor (MPC), neck dissection post RT and age at randomisation in ARTSCAN were associated to late aspiration. Mean dose to the superior pharyngeal constrictor (SPC) and swallowing complaints at baseline were associated to patient reported choking at both time-points. Three separate risk groups for late aspiration, and two risk groups for late patient-reported choking were identified based on number of risk factors. The size of the electively treated volume could be used as a surrogate for individual OARs predicting late aspiration. Copyright © 2016 The Authors. Published by Elsevier B.V. All rights reserved.

Yousif, Ali; Samannan, Rajesh; Abu-Fadel, Mazen

2018-01-01

Acute renal artery embolism (RAE) is a rare condition associated with significant morbidity and mortality. The treatment strategy for RAE includes anticoagulation with or without thrombolysis or surgical or endovascular embolectomy. We describe here a case presentation of acute RAE secondary to atrial fibrillation treated successfully with Penumbra Indigo Aspiration System, a novel device in peripheral endovascular interventions. Our patient had ongoing symptoms and acute renal failure on presentation with contraindication to thrombolysis given hypertensive emergency. A 6F Penumbra Aspiration catheter was used to aspirate large amounts of thrombus from segmental renal arteries with restoration of flow. Patient's symptoms and renal function returned to baseline after intervention. Penumbra system is used routinely in cerebral endovascular intervention, yet here we describe its potential use in peripheral vascular interventions in addition to a literature review of all available evidence for the different treatment modalities of acute RAE.

The goal of this study was to evaluate the efficacy of simple aspiration of air from the pleural space to prevent increased pneumothorax and avoid chest tube placement in cases of pneumothorax following interventional radiological procedures performed under computed tomography fluoroscopic guidance with the transthoracic percutaneous approach. While still on the scanner table, 102 cases underwent percutaneous manual aspiration of a moderate or large pneumothorax that had developed during mediastinal, lung, and transthoracic liver biopsies and ablations of lung and hepatic tumors (independent of symptoms). Air was aspirated from the pleural space by an 18- or 20-gauge intravenous catheter attached to a three-way stopcock and 20- or 50-mL syringe. We evaluated the management of each such case during and after manual aspiration. In 87 of the 102 patients (85.3%), the pneumothorax had resolved completely on follow-up chest radiographs without chest tube placement, but chest tube placement was required in 15 patients. Requirement of chest tube insertion significantly increased in parallel with the increased volume of aspirated air. When receiver-operating characteristic curves were applied retrospectively, the optimal cutoff level of aspirated air on which to base a decision to abandon manual aspiration alone and resort to chest tube placement was 670 mL. Percutaneous manual aspiration of the pneumothorax performed immediately after the procedure might prevent progressive pneumothorax and eliminate the need for chest tube placement. However, when the amount of aspirated air is large (such as more than 670 mL), chest tube placement should be considered

To compare outcomes using the novel portable endoscopy with that of nasogastric (NG) aspiration in patients with gastrointestinal bleeding. Patients who underwent NG aspiration for the evaluation of upper gastrointestinal (UGI) bleeding were eligible for the study. After NG aspiration, we performed the portable endoscopy to identify bleeding evidence in the UGI tract. Then, all patients underwent conventional esophagogastroduodenoscopy as the gold-standard test. The sensitivity, specificity, and accuracy of the portable endoscopy for confirming UGI bleeding were compared with those of NG aspiration. In total, 129 patients who had GI bleeding signs or symptoms were included in the study (age 64.46 ± 13.79, 91 males). The UGI tract (esophagus, stomach, and duodenum) was the most common site of bleeding (81, 62.8%) and the cause of bleeding was not identified in 12 patients (9.3%). Specificity for identifying UGI bleeding was higher with the portable endoscopy than NG aspiration (85.4% vs 68.8%, P = 0.008) while accuracy was comparable. The accuracy of the portable endoscopy was significantly higher than that of NG in the subgroup analysis of patients with esophageal bleeding (88.2% vs 75%, P = 0.004). Food material could be detected more readily by the portable endoscopy than NG tube aspiration (20.9% vs 9.3%, P = 0.014). No serious adverse effect was observed during the portable endoscopy. The portable endoscopy was not superior to NG aspiration for confirming UGI bleeding site. However, this novel portable endoscopy device might provide a benefit over NG aspiration in patients with esophageal bleeding.

Our purpose was to review needle aspiration of breast abscesses and identify factors associated with treatment by aspiration alone versus aspiration with surgical incision and drainage (I/D). This Institutional Review Board-approved, retrospective review of the breast ultrasound database from 2008 to 2010 identified 40 patients (41 abscesses) who underwent aspiration, with or without I/D. Demographics, imaging, number of aspirations, and microbiology were reviewed. Twenty-two abscesses underwent aspiration only, 16 > 3 cm, 6 ≤ 3 cm (mean 4.3 cm, range 0.9-10 cm). Known risk factors included lactational (11), 3 weeks post partum (1), pregnancy (1), recent biopsy/lumpectomy (5). Nineteen abscesses underwent aspiration and I/D, 15 > 3 cm, 4 ≤ 3 cm (mean 4.1 cm, range 2.2-7.5 cm). Known risk factors included lactational (4), recurrent subareolar abscess (4), diabetes (3), hydradenitis suppuritiva (1), nipple piercing (2), smoking (1), pregnancy (1), HIV (1), and lumpectomy (1). Identified reasons for I/D included lack of improvement/recurrence (12), fistula (3), and one electively after clinical improvement of a recurrent subareolar abscess. Abscesses associated with pregnancy and lactation or breast biopsy are effectively managed with aspiration, even when large. Recurrence, chronicity, or fistula may require surgical intervention. © 2014 Wiley Periodicals, Inc.

Full Text Available Background. Fine-needle aspiration (FNA can cause misdiagnosis of cytomorphological findings between parathyroid and thyroid lesions. Case Presentation. A 31-year-old man presented with a palpable neck mass on the right thyroid lobe. FNA cytology was reported as intrathyroidal lymphoid hyperplasia. After 5 years, repeated FNA was done on the enlarged nodule with result of Hürthle cell lesion. Prior to right lobectomy, laboratories revealed elevated serum calcium and parathyroid hormone (PTH. Careful history taking revealed chronic knee pain and ossifying fibroma at the maxilla. Ultrasonography showed a 2.8 cm mass inferior to right thyroid lobe. Pathology from en bloc resection was parathyroid carcinoma and immunohistochemical study revealed positivity for PTH. Genetic analysis found somatic mutation of CDC73 gene in exon1 (c.70delG which caused premature stop codon in amino acid 26 (p.Glu24Lysfs2*. The final diagnosis was hyperparathyroidism-jaw tumor syndrome. Conclusions. FNA cytology of parathyroid can mimic thyroid lesion. It is important to consider and correlate the entire information from clinical history, laboratory, imaging, and FNA.

Transvaginal color Doppler was used to investigate blood flow in the fetomaternal circulation of 60 women with threatened abortion and 90 women with normal intrauterine pregnancy. The obtained Doppler sonograms were analyzed and the resistance index (RI) was calculated in the maternal circulation, while in the fetal circulation the pulsatility index (PI) was used. There was no significant difference in the RI values of the maternal circulation between women with normal pregnancies and pregnancies complicated by bleeding, but with normal pregnancy outcome (p > 0.05). No differences in RI values of the uterine, arcuate and radial arteries were found between pregnancies with threatened abortion and normal pregnancy outcome and women with abnormal outcome (p > 0.05). In 9 of 21 women with visible retrochorionic hematoma, the RI of the spiral arteries was higher on the hematoma side in comparison to the opposite side (p abortion, the RI of the spiral arteries was lower in comparison to the control group. Such findings could be caused by the vasodilatating products of inflammation which probably exist in such areas. There was no significant difference in terms of the PI of fetal blood vessels between normal pregnancy and threatened abortions with normal outcome, as well as between threatened abortions with normal outcome and subsequent abortions of live fetuses (p > 0.05).

Sensitivity was 91%, specificity 88%, positive predictive value 96.6% and negative predictive value turned to be 71% (pauditing values of fine needle aspiration cytology in our laboratory meet, or in certain aspects exceed the proposed minimum threshold values.

Total bilirubin in nasogastric aspirates: A potential new indicator of postoperative gastrointestinal recovery

Directory of Open Access Journals (Sweden)

Go Miyano

2013-01-01

Full Text Available Background: The aim of our study was to investigate if total bilirubin (T-bil, amylase (Amy, and sodium (Na in nasogastric (NG aspirates can reflect gastrointestinal motility reliably. Materials and Methods: NG aspirates from all laparotomies lasting more than 150 min in children less than 12 months old were studied for 3 months. Color of aspirates and intensity of bowel sounds were graded every 3 h by nursing staff and aspirate samples for measuring T-bil, Amy, and Na were collected independently every 12 h until an oral fluid challenge was tolerated. Results: There were 26 subjects. Mean age at surgery was 5.6 months; mean body weight at surgery was 5.8 kg. No postoperative complications occurred. While there was no reduction in average volume of NG aspirates, color change was subjective, and bowel sounds could not be standardized, T-bil decreased over time (0d: 4.4 mg/dL; 0.5d: 2.7 mg/dL; 1.0d: 1.6 mg/dL; 1.5d: 1.3 mg/dL; 2.0d: 0.4 mg/dL; 2.5d: 0.33 mg/dL; 3.0d: 0.21 mg/dL; 3.5d: 0.15 mg/dL; 4.0d: 0.06 mg/dL; 4.5d: 0.05 mg/dL; 5.0d: 0.02 mg/dL; 5.5d: 0.02 mg/dL; 6.0d: 0.01 mg/dL. Amy and Na were inconclusive. Conclusion: T-bil levels in NG aspirates may be useful as a reliable objective quantitative marker of gastrointestinal motility postoperatively.

Can anyone screen for deep infiltrating endometriosis with transvaginal ultrasound?

Piessens, Sofie; Healey, Martin; Maher, Peter; Tsaltas, Jim; Rombauts, Luk

2014-10-01

Surgical treatment of deep infiltrating endometriosis (DIE) is complex, and preoperative diagnosis benefits both surgeon and patient. Studies in expert centres have reported high accuracy for transvaginal ultrasound (TVUS) diagnosis of DIE. External validation of these findings has been limited, and no information is available on how quickly these skills can be acquired. The aim of this study was to measure the learning curve of DIE-TVUS and to identify the causes for inaccuracies in the diagnosis of bowel lesions and Pouch of Douglas (POD) obliteration. Following one week of training at the University of São Paulo (Brazil), 205 consecutive women with a history of endometriosis symptoms were prospectively assessed by TVUS after minimal bowel preparation. TVUS findings were correlated with laparoscopic findings in eighty-five cases to assess the accuracy. The LC-CUSUM and CUSUM were used to assess the learning curve and maintenance of competency, respectively. The sensitivity and specificity for DIE of the bladder, vagina and bowel were 33% and 100%, 80% and 100%, and 88% and 93%, respectively. The sensitivity and specificity for the presence of POD obliteration were 88% and 90%, respectively. LC-CUSUM analysis confirmed that competency for DIE-TVUS was achieved within 38 scans for the detection of POD obliteration and within 36 scans for the detection of bowel nodules. Competency was maintained for the remainder of the scans as assessed by the CUSUM. After one week of DIE-TVUS training, competency can be achieved within forty procedures, allowing diagnosis of DIE with similar diagnostic accuracy as reported by centres of excellence. © 2014 The Royal Australian and New Zealand College of Obstetricians and Gynaecologists.

Ultrasound guided percutaneous fine needle aspiration biopsy of the liver with focal lesion

International Nuclear Information System (INIS)

Ko, Gang Seok; Yang, Hyun Cheol; Park, Byoung Lan; Kim, Byoung Geun; Sohn, Jang Sihn

1985-01-01

The ultrasound-guided fine needle aspirations were performed in order to diagnose a suspected neoplastic or infectious disease in 52 patients with focal liver disease. Of these, neoplastic lesions were suspected in 31 patients and infectious lesions in 21 patients ultrasonically and/or clinically. The overall accuracy for both suspected malignant and infectious disease was 79% (41/52). The primary indication for fine needle aspiration was to document the presence of malignancy and to avoid a diagnostic laparotomy, and to drain hepatic abscess. Consequently we were convinced that the ultrasound-guided percutaneous fine needle aspiration biopsy in the focal liver disease is the best method for a conclusive diagnosis

Transvaginal ultrasound appearances of the ovary in normal women and hirsute women with oligomenorrhoea.

Science.gov (United States)

Fox, R

1999-02-01

The transvaginal ultrasound appearances of the ovary were determined in women with clinical and endocrine features of polycystic ovarian disease (PCOD) and apparently normal women. At scan the number of small follicles were counted and ovarian volume was calculated. The maximum width of the ovarian cortex was also measured. Blood was sent for measurement of LH, FSH and testosterone. The women with oligomenorrhoea were scanned at random and the normal women were seen within the first 5 days of the start of menstruation. There were significant differences between median values for the 2 groups in terms of number of small follicles, ovarian volume and stromal width; the ovaries of the hirsute women had more follicles, were of larger volume, and had greater stromal width. The 2 ranges for number of follicles did overlap, however. Four hirsute oligomenorrhoeic women had a normal number of follicles; all 4 had the several clinical and endocrine features indicative of PCOD. These data suggest that the classical ultrasound features of PCOD are not consistently present and that the absence of increased follicularity at scan should not necessarily deter clinicians from making the functional diagnosis of PCOD.

Gray, R.A.; Williams, P.L.; Dubbins, P.A.; Jenks, P.J.

2012-01-01

Aim: To determine the national practice of transvaginal ultrasound (TVUS) probe decontamination in English hospitals and to develop recommendations for guidance. Materials and methods: A literature review was undertaken to clarify best practice and evaluate methods of decontamination of TVUS probes. A questionnaire was developed to ascertain TVUS probe decontamination programmes in current use within English hospitals. This was sent to ultrasound leads of 100 English hospitals; 68 hospitals responded. Results: There is a wide variation in TVUS probe decontamination across English hospitals. Although the majority of respondents (87%, 59/68) reported having clear and practical written guidelines for TVUS decontamination, the frequency, methods, and types of decontamination solutions utilized were widely variable and none meet the standards required to achieve high-level disinfection. Conclusion: While the decontamination of other endoluminal medical devices (e.g., flexible endoscopes) is well defined and regulated, the decontamination of TVUS probes has no such guidance. There appears to be incomplete understanding of the level of risk posed by TVUS probes, and in some cases, this has resulted in highly questionable practices regarding TVUS hygiene. There is an urgent need to develop evidence-based national guidance for TVUS probe decontamination.

The primary therapy for deep tissue abscesses is drainage accompanied by systemic antimicrobial treatment. However, the long antibiotic course required increases the probability of acquired resistance, and the high incidence of polymicrobial infections in abscesses complicates treatment choices. Photodynamic therapy (PDT) is effective against multiple classes of organisms, including those displaying drug resistance, and may serve as a useful adjunct to the standard of care by reduction of abscess microbial burden following drainage. Aspirates were obtained from 32 patients who underwent image-guided percutaneous drainage of the abscess cavity. The majority of the specimens (24/32) were abdominal, with the remainder from liver and lung. Conventional microbiological techniques and nucleotide sequence analysis of rRNA gene fragments were used to characterize microbial populations from abscess aspirates. We evaluated the sensitivity of microorganisms to methylene blue-sensitized PDT in vitro both within the context of an abscess aspirate and as individual isolates. Most isolates were bacterial, with the fungus Candida tropicalis also isolated from two specimens. We examined the sensitivity of these microorganisms to methylene blue-PDT. Complete elimination of culturable microorganisms was achieved in three different aspirates, and significant killing (P abscess treatment. © 2013 Wiley Periodicals, Inc.

2017-01-01

The objective of this systematic review was to characterize chest CT findings in patients with dysphagia and pulmonary aspiration, identifying the characteristics and the methods used. The studies were selected from among those indexed in the Brazilian Virtual Library of Health, LILACS, Indice Bibliografico Espanol de Ciencias de la Salud, Medline, Cochrane Library, SciELO, and PubMed databases. The search was carried out between June and July of 2016. Five articles were included and reviewed, all of them carried out in the last five years, published in English, and coming from different countries. The sample size in the selected studies ranged from 43 to 56 patients, with a predominance of adult and elderly subjects. The tomographic findings in patients with dysphagia-related aspiration were varied, including bronchiectasis, bronchial wall thickening, pulmonary nodules, consolidations, pleural effusion, ground-glass attenuation, atelectasis, septal thickening, fibrosis, and air trapping. Evidence suggests that chest CT findings in patients with aspiration are diverse. In this review, it was not possible to establish a consensus that could characterize a pattern of pulmonary aspiration in patients with dysphagia, further studies of the topic being needed. (author)

Acute lung injury/acute respiratory distress syndrome (ALI/ARDS) is a manifestation of systemic inflammation in the lungs, but the factors that trigger inflammation in ALI/ARDS are unclear. We hypothesized that neutrophil extracellular traps (NETs) contribute to the pathogenesis of acid aspiration-induced ALI/ARDS. Analysis of bronchial aspirates from ARDS patients showed that NETs were significantly correlated with the degree of ARDS (r = -0.5846, p = 0.0359). NETs in bronchoalveolar lavage fluid of acid-aspiration mice were significantly higher (141.6 ± 23.08) at 3 h after injury than those in the sham group (1234 ± 101.9; p = 0.003, n = 5 per group). Exogenous NETs aggravated lung injury, while alvelestat and DNase markedly attenuated the intensity of ARDS. We investigated whether NETs are involved in the severity of gastric aspiration-induced ARDS. Then, a hydrochloric acid aspiration-induced ALI murine model was used to assess whether NETs are pathogenic and whether targeting NETs is protective. Exogenous NETs were administered to mice. Alvelestat can inhibit neutrophil elastase (NE), which serves an important role in NET formation, so we investigated whether alvelestat could protect against ALI in cell and mouse models. NETs may contribute to ALI/ARDS by promoting tissue damage and systemic inflammation. Targeting NETs by alvelestat may be a potential therapeutic strategy.

The frequent association of asthma and paranasal sinusitis has been ascribed to a nasobronchial reflex, aspiration of sinus secretions, or enhanced beta-adrenergic blockade. We investigated possible pulmonary aspiration in a pilot study (eight patients) and follow-up study (13 patients) by means of a radionuclide technique. In the pilot study, the aim was to demonstrate aspiration as well as visibility of the radionuclide in the thorax during a period of 24 hours. The radionuclide was initially placed bronchoscopically in the bronchial tree in four patients and was still clearly visible in the same position after 24 hours in three patients. Aspiration from the nasopharynx was unequivocally demonstrated in two of four patients with depressed consciousness. The follow-up study population consisted of four patients with maxillary sinusitis only and nine patients with sinusitis and asthma. The radionuclide was placed in a maxillary sinus during therapeutic puncture. In the patients with only sinusitis as well as patients with asthma and sinusitis the radionuclide could be demonstrated in the maxillary sinus, nasopharynx, esophagus, and lower gastrointestinal tract during a 24-hour period. However, no pulmonary aspiration of radionuclide could be demonstrated in any patient. We conclude that seeding of the lower airways by mucopurulent secretions is unlikely to account for coexistent pulmonary disease. The association is probably related to generalized mucosal disease affecting both upper and lower airways

All abnormalities except one were found at SCSH, while TVS alone missed polyps and had almost one in four equivocal findings. The use of TVS, without saline contrast, left one in five of the polyps undiagnosed in referred patients with abnormal bleeding....

Aspiration tests in aqueous foam using a breathing simulator

Non-toxic aqueous foams are being developed by Sandia National Laboratories (SNL) for the National Institute of Justice (NIJ) for use in crowd control, cell extractions, and group disturbances in the criminal justice prison systems. The potential for aspiration of aqueous foam during its use and the resulting adverse effects associated with complete immersion in aqueous foam is of major concern to the NIJ when examining the effectiveness and safety of using this technology as a Less-Than-Lethal weapon. This preliminary study was designed to evaluate the maximum quantity of foam that might be aspirated by an individual following total immersion in an SNL-developed aqueous foam. A.T.W. Reed Breathing simulator equipped with a 622 Silverman cam was used to simulate the aspiration of an ammonium laureth sulfate aqueous foam developed by SNL and generated at expansion ratios in the range of 500:1 to 1000:1. Although the natural instinct of an individual immersed in foam is to cover their nose and mouth with a hand or cloth, thus breaking the bubbles and decreasing the potential for aspiration, this study was performed to examine a worst case scenario where mouth breathing only was examined, and no attempt was made to block foam entry into the breathing port. Two breathing rates were examined: one that simulated a sedentary individual with a mean breathing rate of 6.27 breaths/minute, and one that simulated an agitated or heavily breathing individual with a mean breathing rate of 23.7 breaths/minute. The results of this study indicate that, if breathing in aqueous foam without movement, an air pocket forms around the nose and mouth within one minute of immersion.

Objective: To determine the safety and efficacy of selective thrombus aspiration during Primary Percutaneous Coronary Intervention (PCI). Methods: This observational prospective study was conducted in the catheterization laboratory of a tertiary care cardiovascular centre. A total of 150 consecutive patients who underwent primary PCI were enrolled. Aspiration was done only when thrombus burden was considered significant. After completion of procedure angiographic and electrocardiographic signs were recorded and clinical follow up was documented up to 1 year. Results: No significant difference among the groups was found in age, height, weight and other risk factors like Hypertension, Diabetes Mellitus and Smoking. In general, left anterior descending artery was culprit in 65 % of patients and more than 90 % of culprit vessels had visible thrombus. Multivessel disease was present in 38 % of patients and 22.7% had past history of myocardial infarction. Out of 150 patients 117 (78%) underwent thrombus aspiration. No significant difference was found in ST resolution within 60 minutes (72.6 vs 81.8 %; P<0.285) and myocardial blush grade II and III (41.9 vs 27.3 %; P<0.128). No difference in event free survival was observed among the two groups (80.3 vs 84.8 %; P<0.708) at one year. Conclusion: Selective thrombus aspiration in definite thrombus laden arteries and no aspiration in low or negligible thrombus burden vessels may be a safe and effective strategy in patients undergoing primary PCI. Overall poor risk profile of our patients as compared to western population necessitates further evaluation of this matter in randomized studies. (author)

Full Text Available The aim of this study was to compare the goals and aspirations of learners from single- and two-parent families. The study used a quantitative methodology with a cross-sectional comparative group design. The sample consisted of 853 Grade 11 learners from secondary schools in the Northern, Southern and Metro Central education districts in the Western Cape. The data were collected using the Aspirations Index and a short biographical questionnaire. The results suggest that there was a significant main effect of family structure on certain goals and aspirations of learners in secondary schools. These goals and aspirations included wealth, image, personal growth, relationships, and health. Furthermore, learners in single-parent families placed more emphasis on intrinsic goals.

Accurate detection and classification of aspiration is a critical component of videofluoroscopic swallowing evaluation, the most commonly utilized instrumental method for dysphagia diagnosis and treatment. Currently published literature indicates that inter-judge reliability for the identification of aspiration ranges from poor to fairly good depending on the amount of training provided to clinicians. The majority of extant studies compared judgments among clinicians. No studies included judgments made during the use of a postural compensatory strategy. The purpose of this study was to examine the accuracy of judgments made by speech-language pathologists (SLPs) practicing in hospitals compared with unblinded expert judges when identifying aspiration and using the 8-point Penetration/Aspiration Scale. Clinicians received extensive training for the detection of aspiration and minimal training on use of the Penetration/Aspiration Scale. Videofluoroscopic data were collected from 669 patients as part of a large, randomized clinical trial and include judgments of 10,200 swallows made by 76 clinicians from 44 hospitals in 11 states. Judgments were made on swallows during use of dysphagia compensatory strategies: chin down posture with thin-liquids and thickened liquids (nectar-thick and honey-thick consistencies) in a head neutral posture. The subject population included patients with Parkinson’s disease and/or dementia. Kappa statistics indicate high accuracy for all interventions by SLPs for identification of aspiration (all К > .86) and variable accuracy (range 69%–76%) using the Penetration/Aspiration Scale when compared to expert judges. It is concluded that while the accuracy of identifying the presence of aspiration by SLPs is excellent, more extensive training and/or image enhancement is recommended for precise use of the Penetration/Aspiration Scale.

Lipid aspiration pneumonia due to gastroesophageal reflux. An unusual radiographic appearance

Energy Technology Data Exchange (ETDEWEB)

1989-08-01

The development of lipid aspiration pneumonia after chronic nasopharyngeal installation of mineral oil was first described in 1925 by Laughlin. Since that time this entity has been well recognized and numerous substances have been identified or implicated as the aspirated material. The classic radiographic appearance of severe chronic lipid aspiration pneumonia has been described as consisting of intense perihilar infiltrates. However, the radiographic findings are more often non-specific and usually consist of varying degrees of diffuse interstitial infiltrates that tend to be more prominent in the perihilar regions and the right lung. We are reporting a case of biopsy-proven lipid aspiration pneumonia in an infant with known gastro-esophageal reflux (GER) who had medium-chain triglyceride oil administered via nasogastric tube. Serial roentgenograms demonstrated a changing pulmonary pattern from diffuse bilateral interstitial infiltrates initially to a diffuse alveolar pattern at the time of the lung biopsy. Modern medicine has developed new methods for providing nourishment to sick newborns and infants to improve their nutritional status and help them to grow. One such method involves the administration of medium-chain triglycerides (MCT oil) into the GI tract via a nasogastric or nasoenteral tube. The purpose of this report is to describe a significant complication of this method of providing nutrition to an infant with gastroesophageal reflux (GER) and the diagnostic dilemma it presented.

Full Text Available A 27 year old female presented for fertility preservation prior to undergoing pelvic radiotherapy. She had previously undergone a radical laparoscopic hysterectomy for cervical carcinoma seven months earlier. A trans-vaginal oocyte aspiration was not advisable due to a vaginal recurrence of the disease. Due to a polycystic ovarian morphology (PCO, follicle stimulating hormone (FSH priming with no human chorionic gonadotrophin (hCG trigger was performed prior to oophorectomy followed by ex-vivo oocyte aspiration and in vitro maturation (IVM. All visualized follicles were punctured and follicular fluid aspirated. There were 22 immature oocytes identified and placed into maturation culture for 24 h. After this time, 15 oocytes were deemed to be mature and suitable for vitrification. Following an additional 24 h in maturation culture of the remaining 7 oocytes, three more were suitable for cryopreservation. The patient recovered well and progressed to radiotherapy three days later. This report demonstrates the use of IVM treatment to store oocytes for oncology patients in time-limited circumstances.

2018-01-01

Abstract Rationale: In patients with oropharyngeal and nasopharyngeal bleeding, blood aspiration can make airway management difficult and lead to severe pulmonary complications. Patient concerns: A 44-year-old male patient with recurrent epistaxis underwent surgery for hemostasis. The patient aspirated blood through the endotracheal tube when he hiccupped during the surgery. Diagnosis: The patient was diagnosed with blood aspiration after intraoperative fiberoptic bronchoscopy revealed a blood clot and viscous mucus in the airways, but no sign of active bleeding. Interventions: Tracheobronchial suctioning and irrigation with normal saline was performed through the bronchoscope to remove the aspirated blood clot. Prior to emergence from anesthesia, sugammadex was administered to induce complete neuromuscular recovery and enable the patient to cough up any blood remaining in the airways. Outcomes: The patient was successfully extubated and fully recovered with no complications. Lessons: Blood aspiration due to oropharyngeal or nasopharyngeal bleeding can be diagnosed and treated by tracheobronchial suctioning via fiberoptic bronchoscopy. In addition, sugammadex can enable patients to recover spontaneous breathing, facilitate extubation, and enable patients to cough up any blood remaining in the airways. PMID:29642212

Our objective was to determine whether the Toyota Production System process redesign resulted in diagnostic error reduction for patients who underwent cytologic evaluation of thyroid nodules. In this longitudinal, nonconcurrent cohort study, we compared the diagnostic error frequency of a thyroid aspiration service before and after implementation of error reduction initiatives consisting of adoption of a standardized diagnostic terminology scheme and an immediate interpretation service. A total of 2,424 patients underwent aspiration. Following terminology standardization, the false-negative rate decreased from 41.8% to 19.1% (P = .006), the specimen nondiagnostic rate increased from 5.8% to 19.8% (P Toyota process change led to significantly fewer diagnostic errors for patients who underwent thyroid fine-needle aspiration.

2016-01-01

Using Children of Immigrants Longitudinal Study (CILS), this study examined the links between strain, psychological conflicts, aspiration-attainment gap, and depressive tendencies of 755 youth of Mexican origin. Two research questions were raised: (a) What types of strain and psychological conflict induced depressive tendencies? (b) What types of aspirations were relevant to these depressive symptoms? Overall, this study showed that factors implicated by collision of values, perceived discrepancies between aspiration and attainment, and negative appraisal of self could induce depressive mood, feelings, and behaviors, an important finding revealing that this underserved population can benefit from better public health services.

Full Text Available Abstract The aim of this study was to detect possible associations between respiratory pathogens from tracheal aspirate and oral biofilm samples in intubated patients in an intensive care unit (ICU, and to identify the most common respiratory pathogens in oral biofilm, particularly in patients that developed ventilator-associated pneumonia (VAP. Two oral biofilm samples were collected from the tongue of intubated patients (at admission and after 48 hours and analyzed by culture with the Antibiotic Sensitivity Test. The results from the tongue biofilm samples were compared with the tracheal secretions samples. A total of 59.37% of patients exhibited the same species of pathogens in their tracheal aspirate and oral biofilm, of which 8 (42.1% developed VAP, 10 (52.63% did not develop pneumonia and one (5.26% had aspiration pneumonia. There was a statistically significant association between presence of microorganisms in the tracheal and mouth samples for the following pathogens: Klebsiella pneumoniae, Candida albicans, Pseudomonas aeruginosa, Enterobacter gergoviae, Streptococcus spp and Serratia marcescens (p < 0.05. Pathogens that are present in tracheal aspirates of intubated patients can be detected in their oral cavity, especially in those who developed VAP or aspiration pneumonia. Thus, the results indicate that an improved oral care in these patients could decrease ICU pneumonia rates.

Pinn Siraprapasiri

2016-01-01

Full Text Available This article assesses the knowledge of, attitudes towards, and aspirations for ASEAN among Thai university students, who are set to enter the ASEAN Community labour market and are among those most in touch with ASEAN issues. It uses data obtained from a countrywide survey and focus group discussions to identify variables that affect knowledge, attitudes, and aspirations and to explore the relationships between knowledge, attitudes, and aspirations. The quantitative analysis conducted here uses students’ fields of study, academic performance, and exposure to both ASEAN-related courses and also information and discussions about ASEAN in the mass media and public forums as predictors of their level of knowledge about ASEAN. The paper’s results confirm that positive attitudes towards ASEAN lead to positive aspirations for ASEAN. They also reveal that significant knowledge about ASEAN cannot, in isolation, adequately explain students’ attitudes towards ASEAN and does not always lead to positive attitudes. These findings and those obtained from the focus group discussions suggest that a high level of knowledge and understanding of fellow ASEAN member countries and their people – whether attained through formal or informal education or social interaction – is needed for students to develop positive attitudes and become aspiring members of the ASEAN Community.

Although broncho-alveolar lavage (BAL) culture and protected specimen brush (PSB) are regarded as the most effective methods in the diagnosis of VAP, a simple endotracheal aspiration (EA) is frequently performed during routine care, because of its simplicity and low cost. We compared the effectiveness of EA with BAL and PSB in VAP patients. Sixty-one adult VAP patients, ventilated for longer than 48 h, were cultured with all three methods. Positive cultures were obtained from 63.9% of patients, with Acinetobacter baumannii being the most common pathogen. There was a high positive correlation between simple aspirates and BAL (k 0.817, CI 0.664-0.840, p aspirates and PSB (k 0.667, CI 0.483-0.871, p aspirate culturing, compared to BAL and PSB, it can be used successfully in most cases.

Understanding gendered aspects of migration aspiration and motives of university students by multivariate statistical methods

2014-03-01

Full Text Available The paper deals with the application of multivariate analysis of variance and logistic regression in measuring, explaining and evaluating (i gender differences in expressing migration aspirations, and (ii a gender effect on migration motivation of university students in Croatia. The results supported the thesis that migration is a complex gendering process that assumes subjective assessment of the whole set of interrelated motives. According to logistic regression, gender is a significant predictor of migration aspirations among the selected demographic and socio-economic variables. A multivariate analysis of variance showed that gender and migration aspirations in interaction matter when it comes to migration motives, particularly related to the perceived importance of social networks. Females, and especially those who aspire to migrate, assessed these motives as more important than males.

Cost-Effectiveness Analysis of Interventions to Reduce Risk of Aspiration in Elderly Cancer Survivors Residing in Skilled Nursing Facilities.

Science.gov (United States)

Mantravadi, S

2017-04-01

Aspiration can occur in patients of any age group, but it can be prevented. The primary population at risk is made up of survivors of cancer because of their increased risk of mucositis, mucosal atrophy, and dysphagia associated with chemotherapy, radiotherapy, and the disease process itself. The rate of incidence of aspiration cannot be quantified, because minor cases of aspiration often go unreported. Sequelae ensuing from aspirations can include pneumonia, end-stage kidney disease, dialysis, and death. Analyses of cost, decision-tree modeling, and cost effectiveness were performed to compare a hypothetical, interventional model based on best practices with usual (standard) care. A societal perspective was used as the economic view point. Direct costs, caregiver time, and market values for wages were estimated for the 2 interventions. Effectiveness values for the cost-effectiveness and decision-tree analyses were obtained from the literature. The incremental-cost-effectiveness ratio was calculated and used to compare the intervention with usual care. The interventional method was more costly but more effective than usual care. A sensitivity analysis considered the uncertainty of event probability (aspiration vs no aspiration). The interventional protocol for aspiration reduction continued to be more cost effective than usual care. Aspiration takes a financial toll on all facets of health care, including on nurses, skilled nursing facilities, patients, their families, and insurers, among others. Implementing guidelines that describe best practices for aspiration appears to be a cost-effective strategy for reducing aspirations among cancer survivors - especially elderly patients - who live in skilled nursing facilities.

Few researchers have explored future educational aspirations as a promotive factor against exposure to community violence in relation to adolescents' violent behavior over time. The present study examined the direct and indirect effect of exposure to community violence prior to 9th grade on attitudes about violence and violent behavior in 12th grade, and violent behavior at age 22 via 9th grade future educational aspirations in a sample of urban African American youth (n = 681; 49% male). Multi-group SEM was used to test the moderating effect of gender. Exposure to violence was associated with lower future educational aspirations. For boys, attitudes about violence directly predicted violent behavior at age 22. For boys, future educational aspirations indirectly predicted less violent behavior at age 22. Implications of the findings and suggestions for future research are discussed. Copyright © 2015 The Foundation for Professionals in Services for Adolescents. Published by Elsevier Ltd.

Sixty-three patients (35 women and 28 men; age range, 29-86 years; mean age, 71 years) with clinically suspected septic hip prosthesis were prospectively studied with independent review board (IRB) approval. Volume and microbiological cultures of aspirated fluid and several computed tomography imaging findings such as periprosthetic fluid collections, prosthetic acetabular malposition, and heterotopic ossification were analyzed. All patients underwent revision surgery and infection was finally diagnosed in 33 patients. Statistical comparative analysis was performed comparing computed tomography aspiration and surgical findings (95% CI; level of significance at P = 0.05 two-sided) with 70% sensitivity, 100% specificity, 84% accuracy, 100% positive predictive value, and 75% negative predictive value. Using Fisher's exact test, the presence of periprosthetic fluid collections (P = 0.001), prosthetic acetabular malposition (P = 0.025) and aspirated fluid volume (P = 0.009) were significantly higher in infected than in non-infected prostheses, whereas heterotopic ossification was not (P = 0.429). Computed tomography aspiration is accurate to preoperatively diagnose septic hip prosthesis on the basis of volume and bacterial cultures of aspirated joint fluid. Furthermore, imaging findings such as periprosthetic fluid collections and prosthetic acetabular malposition strongly suggest infected prosthesis. (orig.)

Full Text Available Low participation rates in science are a matter of  international concern and existing evidence suggests that children’s science  aspirations are largely formed within the critical 10-14 age period. This presentation explores how families can shape young children’s science aspirations, using Bourdieu’s concept of  habitusto map family resources and practices. This paper  draws on two research projects: ASPIRES and Interests andRecruitment in Science (IRIS. Findings from the ASPIRES project draw on qualitative data from 160 semi-structured interviews (92 school children age 10 and 78 parents, collected as part of an ongoing 5-year longitudinal study in theUK. Findings are contextualised with reference to a survey of over 9,000 elementary school children in England (age 10 collected as part of the wider study. A typology of eight key family ‘habituses’ is developed, ranging  from families in which science is strongly embedded, through to ambivalentcontexts and those in which science is weakly or peripherally embedded. It discusses the implications of each for promoting, or deterring, children’s science aspirations. The IRIS project was aimed to develop knowledge andrecommendations informed by evidence on how young people, and womenin particular, may be attracted to, and retained in, STEM higher education. Specifically, the project addresses the following questions: 1. What are the  priorities, values and experiences on which young people base their educational choice? 2. What are the success factors for interventions aimed at  recruiting more young people (women in particular to higher STEM education? and 3. How do STEM students who drop out/opt out before graduation, explain their choice? The main instrument is a questionnaire (IRIS Q that was completed by almost 6,000 first-year STEM students in the five IRIS consortium countries in 2010.

Full Text Available BACKGROUND The bone marrow examination is an essential investigation for the diagnosis of disorders of the blood and bone marrow. This simple and relatively safe procedure is important, particularly in resource poor centres since access to adjuvant diagnostic techniques are often lacking or absent. MATERIALS AND METHODS 189 patients of all age groups were studied for haematological and non-haematological disorders by bone marrow aspiration in the Department of Pathology, MGM Medical College during the period of 2014 to 2016. RESULTS Majority of the patients who had bone marrow aspiration were aged 0-15 years. The male-to-female ratio was 1:1.03. Most (97% of the marrow aspirate examined had definitive pathologic features, while 14 (7% were normal marrow elements. Out of 189 cases of bone marrow aspiration, acute leukaemia was the most common haematological disease diagnosed using this procedure. Acute lymphoblastic leukaemia was more common than acute myeloid leukaemia. Aplastic anaemia was seen in 16% cases. Megaloblastic anaemia occurred more commonly than other anaemias. Megaloblastic anaemia was seen in 13 cases (7% and microcytic anaemia was seen in 5 cases (3%. There were 10 cases (5% of Idiopathic Thrombocypenic Purpura. Myelodysplastic syndrome and multiple myeloma was seen in 7% and 2% cases respectively. Storage disorder was seen in 3 cases (2%, out of this 02 cases were Gaucher’s disease and one case was Niemann-Pick’s disease. CONCLUSION Bone marrow examination is an important step to arrive at the confirmatory diagnosis of many haematological disorders. This procedure remains a veritable tool in the diagnosis and management of a wide range of haematological diseases, especially in a resource poor centre.

Full Text Available Aspiration during any kind of injection is meant to ensure that the needle tip is at the desired location during this blind procedure. While aspiration appears to be a simple procedure, it has generated a lot of controversy concerning the perceived benefits and indications. Advocates and opponents of aspiration both make logically sound claims. However, due to scarcity of available data, there is no evidence that this procedure is truly beneficial or unwarranted. Keeping in view the huge number of injections given worldwide, it is important that we draw attention to key questions regarding aspiration that, up till now, remain unanswered. In this review, we have attempted to gather and present literature on aspiration both from published and non-published sources in order to provide not only an exhaustive review of the subject, but also a starting point for further studies on more specific areas requiring clarification. A literature review was conducted using the US National Institute of Health’s PubMed service (including Medline, Google Scholar and Scopus.

When more than one pedestrian want to move to the same site, conflicts appear and thus the involved pedestrians play a motion game. In order to describe the emergence of cooperation during the conflict resolving process, an evolutionary cellular automation model is established considering the effect of aspiration and mean gain. In each game, pedestrian may be gentle cooperator or aggressive defector. We propose a set of win-stay-lose-shrift (WSLS) like rules for updating pedestrian's strategy. These rules prescribe that if the mean gain of current strategy between some given steps is larger than aspiration the strategy keeps, otherwise the strategy changes. The simulation results show that a high level aspiration will lead to more cooperation. With the increment of the statistic length, pedestrians will be more rational in decision making. It is also found that when the aspiration level is small enough and the statistic length is large enough all the pedestrian will turn to defectors. We use the prisoner's dilemma model to explain it. At last we discuss the effect of aspiration on fundamental diagram. (interdisciplinary physics and related areas of science and technology)

MDCT-Guided Transthoracic Needle Aspiration Biopsy of the Lung Using the Transscapular Approach

International Nuclear Information System (INIS)

Rossi, Umberto G.; Seitun, Sara; Ferro, Carlo

2011-01-01

The purpose of this study is to report our preliminary experience using MDCT-guided percutaneous transthoracic needle aspiration biopsy using the transscapular approach in the upper posterolateral lung nodules, an area that it is difficult or hazardous to reach with the conventional approach. Five patients underwent CT-guided percutaneous transthoracic needle aspiration biopsy of the lung via the transscapular approach. A coaxial needle technique was used in all patients. Biopsy was successful in all patients. No major complications were encountered. One patient developed a minimal pneumothorax next to the lesion immediately after biopsy, which resolved spontaneously. MDCT-guided percutaneous transthoracic needle aspiration biopsy of the lung via the transscapular approach is an effective and safe procedure that reduces the risk of pneumothorax in selected patients.

Migration and Social Aspirations: Chinese Cosmopolitanism in Wenzhou Region (China

Directory of Open Access Journals (Sweden)

Irene Rodrigues

2018-04-01

Full Text Available This article explores what motivates the movements of Chinese migrants from China to Portugal. It presents an ethnographic account of social aspirations in Wenzhou, a port city located in South Zhejiang (Southeast China, where post-Mao economic prosperity, allied to the existence of networks of trade and migration, resulted in social and economic inequalities and great social pressure to become rich and successful. Based on ethnographic fieldwork conducted in Wenzhou and in Lisbon (Portugal between 2008 and 2010, this paper argues that Wenzhou migratory projects are a result of modernity aspirations and desires for material modernization articulated with core Chinese values such as filial piety.

To identify the factors associated with pelvic organ prolapse (POP) recurrence after transvaginal mesh (TVM) repair. One hundred and thirteen women with symptomatic POP stage II to IV were scheduled for TVM procedures. All subjects underwent urinalyses and pelvic examination using the POP quantification (POP-Q) staging system before and after surgery. Seven (6.2%) of 113 women reported POP recurrence after a mean follow-up time of 30 months. We performed a univariate analysis of patients' characteristics to identify the predictors of surgical failure after TVM. There was no difference between two groups as to body mass index, POP stage, mesh type, and preoperative urinary symptoms and urodynamic parameters (P>0.05). However, we found that uterine prolapse (P=0.016) and surgical experience (P=0.043) were two significant predictors of surgical failure. Multivariate logistic regression showed similar results. Advanced uterine prolapse and lack of surgical experience were two significant predictors of failure following TVM. POP recurrence after mesh repair appears to be unlikely beyond the learning curve.

The authors examined the relationships of parental expectations and aspirations for their children's educational attainment to children's academic performance in school among 783 immigrant-origin children aged 5-18 years in Canada. The results of hierarchical regression analyses, after accounting for student and family background characteristics, indicated that immigrant parents' expectations and aspirations for their children's educational attainment were positively linked to immigrant-origin children's academic performance in school. Implications of these findings are briefly discussed.

Ventilator associated pneumonia (VAP) is one of the most important causes of mortality in patients treated with invasive mechanical ventilation (IMV) in intensive care unit (ICU). Microbiological examinations are required as clinical and radiological findings are usually insufficient in the diagnosis. Twenty four patients who were receiving IMV because of respiratory failure, had a Clinical Pulmonary Infection Score (CPIS) of ≥ 6 in the follow-up and died with the suspicion of VAP were enrolled in our study. Six patients were excluded as post-mortem biopsy could not be performed. The patients who had pre-mortem CPIS ≥ 6, in whom a causative organism was identified from the culture of post-mortem lung biopsy and/or histopathological examination of lung biopsy was compatible with pneumonia were diagnosed as VAP. In the 18 patients in whom a post-mortem lung biopsy was performed, quantitative culture results of endotracheal aspirate performed 48 hours prior to death were compared with microbiological and histopathological results of post-mortem lung biopsy specimens, and the role of endotracheal aspirate in the diagnosis of VAP was evaluated retrospectively. Out of 18 patients (12 men, mean age 67.0 ± 13.0 years) included in the study, 11 (61.1%) were diagnosed as VAP. The quantitative culture of endotracheal aspirate was positive in 9 (81.8%) out of 11 patients diagnosed as VAP. The sensitivity, specificity, positive and negative predictive values of endotracheal aspirate culture for identifying VAP were found to be 81.8%, 14.3%, 60.0% and 33.3%, respectively. Our study shown that quantitative culture of endotracheal aspirate is a practical and reliable method that can be used for the diagnosis of VAP in patients receiving IMV in ICU and having CPIS ≥ 6.

Some 10%-15% of married couples are affected by a fertility disorder. The number of infertile couples seeking medical assistance has increased dramatically in the past decade. The roles of diagnostic imaging with radiography and US (conventional and transvaginal) is emphasized in the assessment of couples with fertility disorders and an unexpectedly higher incidence of fetal wastage secondary to unsuspected uterine anomalies. The most frequently utilized radiographic examination in infertile patients is hysterosalpingography (HSG). Techniques and complications of HSG are illustrated. The normal anatomy, variants, and congenital anomalies of the uterus and fallopian tubes are demonstrated, as are the numerous abnormalities such as filling defects of the uterine cavity, synechiae, effects of maternal diethylstilbestrol exposure, inflammatory tubal disease, and the more common HSG findings following uterine and tubal surgery. The role of diagnostic imaging in male infertility, including vasography and varicocele detection, are addressed. Conventional and transvaginal US in the management of gynecologic fertility disorders are examined, with an emphasis on follicular monitoring, guided follicular aspirations, endometrial evaluations, and evaluation of other disorders (such as endometriosis) associated with infertility

Full Text Available In patients with a new and suddenly beginning of bronchial asthma and repetitive respiratory infection, one should consider the possibility of obstruction by a foreign body. In this case we present a male patient with pneumonia due to aspiration of dental prosthesis. A 32-year-old man presented with a 4-month history of dyspnea, chest pain and new    compliants of diaphoresis and fever persistend despite of antibiotic treatment. Then the patient consultated to our chest surgery department. After the physical examination of patient we made the fiberoptic  flexible bronchoscopy according to the uncertain opasity seen in the chest radiography. Later in the operating room, with the patient under general anesthesia, we extracted the aspirated foreign body, dental prosthesis, by rigid bronchoscopy. We should think about the possibility of foreign body aspiration for the patients with suddenly beginning of the complaints such as, bronchial asthma, repetitive respiratory infection, diaphoresis, chest pain and fever. Sometimes people hides the true anamnesis because of be ashamed or amnesia.

The stability of locus equation slopes across stop consonant voicing/aspiration

Sussman, Harvey M.; Modarresi, Golnaz

2004-05-01

The consistency of locus equation slopes as phonetic descriptors of stop place in CV sequences across voiced and voiceless aspirated stops was explored in the speech of five male speakers of American English and two male speakers of Persian. Using traditional locus equation measurement sites for F2 onsets, voiceless labial and coronal stops had significantly lower locus equation slopes relative to their voiced counterparts, whereas velars failed to show voicing differences. When locus equations were derived using F2 onsets for voiced stops that were measured closer to the stop release burst, comparable to the protocol for measuring voiceless aspirated stops, no significant effects of voicing/aspiration on locus equation slopes were observed. This methodological factor, rather than an underlying phonetic-based explanation, provides a reasonable account for the observed flatter locus equation slopes of voiceless labial and coronal stops relative to voiced cognates reported in previous studies [Molis et al., J. Acoust. Soc. Am. 95, 2925 (1994); O. Engstrand and B. Lindblom, PHONUM 4, 101-104]. [Work supported by NIH.

Adolescents' educational aspirations and ethnic background: The case of students of African and Latin American migrant origins in Spain

Carlos J. Gil-Hernández

2018-02-01

Full Text Available Background: Minority students were found to have high educational aspirations, considering their background characteristics. This finding is often attributed to 'migrant optimism.' Yet, whether socioeconomic, educational, or demographic differences between and within ethnic groups mediate and/or moderate students' educational aspirations remains an inconclusive question. Objective: This study investigates the educational aspirations of children of African and Latin American migrants in Spain, looking at four critical factors: (1 family background, (2 educational performance, (3 years lived in Spain, and (4 language used at home. Methods: Data comes from the 2010 General Evaluation of Educational Diagnostic (GEED on lower-secondary students aged 14 (n = 19,293, on average. Multivariate logistic models are applied using mediation and moderation analyses. Results: Results show that (1 minority students have higher college aspirations than students of Spanish origin after accounting for parental socioeconomic status and educational performance; (2 ethnic differentials in aspirations - especially for pupils with Latin American origin - are concentrated among low-performing and disadvantaged students; (3 recent arrival in Spain is not significantly associated with differences in educational aspirations within minority groups; (4 speaking Spanish at home does not lead to differences in aspirations for pupils of African origin. Conclusions: Migrant optimism, as opposed to family language use and years of contact with the Spanish culture and society, seems to be an important factor for the high (net educational aspirations of students from African and Latin American backgrounds. Contribution: The article provides new evidence on ethnic heterogeneity in educational aspirations, being the first that uses representative data from the whole Spanish educational system.

Characterization of the innate immune response to chronic aspiration in a novel rodent model

2007-11-01

Full Text Available Abstract Background Although chronic aspiration has been associated with several pulmonary diseases, the inflammatory response has not been characterized. A novel rodent model of chronic aspiration was therefore developed in order to investigate the resulting innate immune response in the lung. Methods Gastric fluid or normal saline was instilled into the left lung of rats (n = 48 weekly for 4, 8, 12, or 16 weeks (n = 6 each group. Thereafter, bronchoalveolar lavage specimens were collected and cellular phenotypes and cytokine concentrations of IL-1alpha, IL-1beta, IL-2, IL-4, IL-6, IL-10, GM-CSF, IFN-gamma, TNF-alpha, and TGF-beta were determined. Results Following the administration of gastric fluid but not normal saline, histologic specimens exhibited prominent evidence of giant cells, fibrosis, lymphocytic bronchiolitis, and obliterative bronchiolitis. Bronchoalveolar lavage specimens from the left (treated lungs exhibited consistently higher macrophages and T cells with an increased CD4:CD8 T cell ratio after treatment with gastric fluid compared to normal saline. The concentrations of IL-1alpha, IL-1beta, IL-2, TNF-alpha and TGF-beta were increased in bronchoalveolar lavage specimens following gastric fluid aspiration compared to normal saline. Conclusion This represents the first description of the pulmonary inflammatory response that results from chronic aspiration. Repetitive aspiration events can initiate an inflammatory response consisting of macrophages and T cells that is associated with increased TGF-beta, TNF-alpha, IL-1alpha, IL-1beta, IL-2 and fibrosis in the lung. Combined with the observation of gastric fluid-induced lymphocyitic bronchiolitis and obliterative bronchiolitis, these findings further support an association between chronic aspiration and pulmonary diseases, such as obliterative bronchiolitis, pulmonary fibrosis, and asthma.

The Potential Scientist’s Dilemma: How the Masculine Framing of Science Shapes Friendships and Science Job Aspirations

G. Robin Gauthier

2017-02-01

Full Text Available In the United States, girls and boys have similar science achievement, yet fewer girls aspire to science careers than boys. This paradox emerges in middle school, when peers begin to play a stronger role in shaping adolescent identities. We use complete network data from a single middle school and theories of gender, identity, and social distance to explore how friendship patterns might influence this gender and science paradox. Three patterns highlight the social dimensions of gendered science persistence: (1 boys and girls do not differ in self-perceived science potential and science career aspirations; (2 consistent with gender-based norms, both middle school boys and girls report that the majority of their female friends are not science kinds of people; and (3 youth with gender-inconsistent science aspirations are more likely to be friends with each other than youth with gender normative science aspirations. Together, this evidence suggests that friendship dynamics contribute to gendered patterns in science career aspirations.

Fine-needle aspirate cytology suggesting hepatic lipidosis in four cats with infiltrative hepatic disease.

Willard, M D; Weeks, B R; Johnson, M

1999-12-01

Four cats are reported in which cytology smears obtained by ultrasound-guided fine needle aspiration of the liver were interpreted as indicative of hepatic lipidosis. However, histopathology of hepatic tissue samples obtained with Tru-Cut-like needles or wedge biopsy revealed that the cats had inflammatory or neoplastic hepatic disease causing their clinical signs. Fine needle aspiration and cytology may not detect infiltrative lesions, particularly those that are nodular, multifocal, or localised around the portal regions. Fine needle aspirate cytology is a useful diagnostic procedure with many advantages, but care must be taken to avoid diagnosing hepatic lipidosis as the cause of illness when an infiltrative lesion is responsible.

The aims of this study were to measure the levels of bile acids in patients with suspected ventilator-associated pneumonia (VAP) and provide a possible pathway for neutrophilic inflammation to explain its proinflammatory effect on the airway. Bile acid levels were measured by spectrophotometric enzymatic assay, and liquid chromatography mass spectrometry was used to quantify the major bile acids. Alveolar cells were grown on modified air-liquid interface culture inserts, and bile acids were then employed to stimulate the cells. Reverse transcriptase polymerase chain reaction and Western blots were used to determine the involved gene expression and protein levels. The mean (+/- SE) concentration of total bile acids in tracheal aspirates was 6.2 +/- 2.1 and 1.1 +/- 0.4 mumol/L/g sputum, respectively, for patients with and without VAP (p VAP group (p aspiration may reduce the intensity of neutrophilic inflammation in intubated and mechanically ventilated patients in the ICU.

Pneumomediastinum caused by foreign body aspiration in children

Burton, E.M.; Riggs, W.W.; Houston, C.S.

1988-01-01

In a retrospective review of 155 children with tracheobronchial foreign body aspiration (FBA) at LeBonheur Children's Hospital in Memphis, ten patients had pneumomediastinum (PMD) on an initial chest radiograph. Nine of ten presented with PMD, and one had PMD noted after bronchoscopy. In nine, the aspirated object was a nut. In addition to PMD, atelectasis was present in three patients; associated unilateral hyperinflation was present in three, and pneumothorax was present in one patient. In nine patients, PMD was extensive and was associated with obvious interstitial emphysema extending into the axilla or lower neck. Eight patients were less than 2 years of age. In young children, FBA is the most important cause of PMD, as it is relatively common and completely curable. In a child less than 2 years of age with no history of trauma, the radiographic finding of PMD should be considered to be due to FBA until proved otherwise

To present a modified transvaginal bladder neck closure (TV BNC) technique using a posterior urethral flap to minimize the potential risk of ureteral injury and fistula formation. Urethral and bladder neck destruction owing to chronic indwelling urethral catheters in female neurogenic patients is a devastating complication. A retrospective review was performed of all patients undergoing TV BNC at a single institution during a 3-year period. All patients had had a nonfunctional or destroyed urethra because of a long-term indwelling urethral catheter. In brief, the devastated outlet was closed using the dorsally bivalved urethra as a flap that was rotated cephalad onto the incised anterior bladder wall for closure, thereby rotating the suture line high into the retropubic space. A postoperative cystogram was obtained at 2-3 weeks. A total of 11 consecutive female patients with a devastated outlet underwent TV BNC, as described, with placement of a suprapubic tube. One patient experienced failure at 6 weeks postoperatively. The mean follow-up for the entire cohort was 9.6 months (range 1-36). Serial upper tract imaging at the last follow-up visit revealed no new hydroureteronephrosis. The results of our study have shown that TV BNC with a posterior urethral flap provides satisfactory early results. This technique creates a suture line far removed from the ureteral orifices, minimizing the risk of upper tract injury during closure. Also, the rotation of the posterior urethra onto the anterior bladder wall secures the suture line high into the retropubic space, minimizing the risk of failure and postoperative fistula formation.

Hydrocarbon pneumonia is a very uncommon condition resulting from aspiration of mineral oil into the lung. We report the first description of early and sequential high-resolution computed tomographic (HRCT) findings of hydrocarbon pneumonia following attempted suicide by white spirit aspiration. Initial HRCT showed patchy opacities of coalescing masses with well-defined walls. They were visible in the middle lobe, lingula and lower lobes. Follow-up CT showed regression of the alveolar opacities, the presence of pneumatoceles and right asymptomatic pneumothorax. After 23 months of follow-up, the patient remained asymptomatic, and the follow-up CT scan was considered normal. The radiological features and a review of the relevant literature are briefly discussed. (orig.)

Increasing data supports the role of bacterial inflammation in adverse events of cardiovascular and cerebrovascular diseases. In our previous research, DNA of bacterial species found in coronary artery thrombus aspirates and ruptured cerebral aneurysms were mostly of endodontic and periodontal origin, where Streptococcus mitis group DNA was the most common. We hypothesized that the genomes of S mitis group could be identified in thrombus aspirates of patients with lower limb arterial and deep venous thrombosis. Thrombus aspirates and control blood samples taken from 42 patients with acute or acute-on-chronic lower limb ischemia (Rutherford I-IIb) owing to arterial or graft thrombosis (n = 31) or lower limb deep venous thrombosis (n = 11) were examined using a quantitative real-time polymerase chain reaction to detect all possible bacterial DNA and DNA of S mitis group in particular. The samples were considered positive, if the amount of bacterial DNA in the thrombus aspirates was 2-fold or greater in comparison with control blood samples. In the positive samples the mean difference for the total bacterial DNA was 12.1-fold (median, 7.1), whereas the differences for S mitis group DNA were a mean of 29.1 and a median of 5.2-fold. Of the arterial thrombus aspirates, 57.9% were positive for bacterial DNA, whereas bacterial genomes were found in 75% of bypass graft thrombosis with 77.8% of the prosthetic grafts being positive. Of the deep vein thrombus aspirates, 45.5% contained bacterial genomes. Most (80%) of bacterial DNA-positive cases contained DNA from the S mitis group. Previous arterial interventions were significantly associated with the occurrence of S mitis group DNA (P = .049, Fisher's exact test). This is the first study to report the presence of bacterial DNA, predominantly of S mitis group origin, in the thrombus aspirates of surgical patients with lower limb arterial and deep venous thrombosis, suggesting their possible role in the pathogenesis of

For management of pneumothorax that occurs without underlying lung disease, also referred to as primary spontaneous pneumothorax, simple aspiration is technically easier to perform than intercostal tube drainage. In this systematic review, we seek to compare the clinical efficacy and safety of simple aspiration versus intercostal tube drainage for management of primary spontaneous pneumothorax. This review was first published in 2007 and was updated in 2017. To compare the clinical efficacy and safety of simple aspiration versus intercostal tube drainage for management of primary spontaneous pneumothorax. We searched the Cochrane Central Register of Controlled Trials (CENTRAL; 2017, Issue 1) in the Cochrane Library; MEDLINE (1966 to January 2017); and Embase (1980 to January 2017). We searched the World Health Organization (WHO) International Clinical Trials Registry for ongoing trials (January 2017). We checked the reference lists of included trials and contacted trial authors. We imposed no language restrictions. We included randomized controlled trials (RCTs) of adults 18 years of age and older with primary spontaneous pneumothorax that compared simple aspiration versus intercostal tube drainage. Two review authors independently selected studies for inclusion, assessed trial quality, and extracted data. We combined studies using the random-effects model. Of 2332 publications obtained through the search strategy, seven studies met the inclusion criteria; one study was ongoing and six studies of 435 participants were eligible for inclusion in the updated review. Data show a significant difference in immediate success rates of procedures favouring tube drainage over simple aspiration for management of primary spontaneous pneumothorax (risk ratio (RR) 0.78, 95% confidence interval (CI) 0.69 to 0.89; 435 participants, 6 studies; moderate-quality evidence). Duration of hospitalization however was significantly less for patients treated by simple aspiration (mean

To estimate the safety and efficacy of performing concurrent anterior and posterior transvaginal mesh surgery using a commercially available kit (Gynecare PROLIFT Pelvic Floor Repair System; Ethicon, Inc., Somerville, NJ) for treatment of advanced urogenital prolapse (stage III or higher, Pelvic Organ Prolapse Quantification [POP-Q] system staging). Case control series study (Canadian Task Force classification II-2). Medical school-affiliated hospital. Forty-three patients with severe prolapse, POP-Q stage III (n=23) or IV (n=20), underwent surgery and were followed up for more than 1 year. In patients with any prolapse greater than stage I, surgery were considered to have functional failure. The Surgical Satisfaction Questionnaire was used for subjective evaluation at 1 year postoperatively. Extensive pelvic reconstructive procedures were primarily performed using a combination of the PROLIFT anterior and posterior pelvic systems (i.e., similar to sparing the intermediate section of the PROLIFT total pelvic system). The concurrent pelvic surgery included sequential vaginal total hysterectomy, perineorrhaphy, and suburethra sling, if indicated. Additional subjective and objective evaluations included POP-Q staging, urodynamic assessment, and preoperative and 12-month postoperative questionnaires. Objective and subjective data were available for 42 patients. The subjective cure rate and objective success rate for prolapse at 12-month follow-up was 95.2% and 97.6%, respectively. Mean follow-up was 15.7 months, operation time was 79.2 minutes, operative blood loss was 109.1 mL, and postoperative hospital stay was 4.1 days. Intraoperative and postoperative complications were minor. All patients voided spontaneously before discharge. One mesh extrusion, no wound defective healing, and no rejection were observed. Two patients developed asymptomatic recurrent rectocele (stage II, POP-Q staging) that required no surgical intervention. Urodynamic parameters related to

In this study, we aimed to determine if the use of cervical auscultation (CA) as an adjunct to the clinical feeding evaluation (CFE + CA) improves the reliability of predicting oropharyngeal aspiration (abbreviated to aspiration) in children. The design of the study is based on open label, randomized controlled trial with concealed allocation. Results from children (<18 years) randomized to either CFE or CFE + CA were compared to videofluoroscopic swallow study (VFSS), the reference standard data. Aspiration was defined using the Penetration-Aspiration Scale. All assessments were undertaken at a single tertiary pediatric hospital. 155 children referred for a feeding/swallowing assessment were randomized into the CFE n = 83 [38 males; mean age = 34.9 months (SD 34.4)] or CFE + CA n = 72 [43 males; mean age = 39.6 months (SD 39.3)] group. kappa statistic, sensitivity, and specificity values, area under receiver operating curve (aROC). No significant differences between groups were found, although CFE + CA (kappa = 0.41, 95 % CI 0.2-0.62) had higher agreement for aspiration detection by VFSS, compared to the clinical feeding exam alone (kappa = 0.31, 95 % CI 0.10-0.52). Sensitivity was 85 % (95 % CI 62.1-96.8) for CFE + CA and 63.6 % (95 % CI 45.1-79.6) for CFE. aROC was not significantly greater for CFE + CA (0.75, 95 % CI 0.65-0.86) than CFE (0.66, 95 % CI 0.55-0.76) across all age groups. Although using CA as an adjunct to the clinical feeding evaluation improves the sensitivity of predicting aspiration in children, it is not sensitive enough as a diagnostic tool in isolation. Given the serious implications of missing the diagnosis of aspiration, instrumental assessments (e.g., VFSS), remain the preferred standard.

Aspiration-induced lung injury can decrease gas exchange and increase mortality. Acute lung injury following acid aspiration is characterized by elevated pulmonary blood flow (PBF) in damaged lung areas in the early inflammation stage. Knowledge of PBF patterns after acid aspiration is important for targeting intravenous treatments. We examined PBF in an experimental model at a later stage (2 hours after injury). Anesthetized Wistar-Unilever rats (n = 5) underwent unilateral endobronchial instillation of hydrochloric acid. The PBF distribution was compared between injured and uninjured sides and with that of untreated control animals (n = 6). Changes in lung density after injury were measured using computed tomography (CT). Regional PBF distribution was determined quantitatively in vivo 2 hours after acid instillation by measuring the concentration of [(68)Ga]-radiolabeled microspheres using positron emission tomography. CT scans revealed increased lung density in areas of acid aspiration. Lung injury was accompanied by impaired gas exchange. Acid aspiration decreased the arterial pressure of oxygen from 157 mmHg [139;165] to 74 mmHg [67;86] at 20 minutes and tended toward restoration to 109 mmHg [69;114] at 110 minutes (P < 0.001). The PBF ratio of the middle region of the injured versus uninjured lungs of the aspiration group (0.86 [0.7;0.9], median [25%;75%]) was significantly lower than the PBF ratio in the left versus right lung of the control group (1.02 [1.0;1.05]; P = 0.016). The PBF pattern 2 hours after aspiration-induced lung injury showed a redistribution of PBF away from injured regions that was likely responsible for the partial recovery from hypoxemia over time. Treatments given intravenously 2 hours after acid-induced lung injury may not preferentially reach the injured lung regions, contrary to what occurs during the first hour of inflammation.

Background/Aims Dysphagia is common in patients with neurological disorders. There is a need to identify patients at risk early by a useful clinical tool to prevent its serious complications. The study aims to determine the ability of the Turkish version of Eating Assessment Tool-10 (T-EAT-10) to detect aspiration in patients with neurological disorders. Methods Two hundred fifty-nine patients with neurological disorders who had complaints about swallowing difficulty and referred for a swallowing evaluation were included. Oropharyngeal dysphagia was evaluated with the T-EAT-10 and videofluoroscopic swallowing study in the same day. The penetration-aspiration scale (PAS) was used to document the penetration and aspiration severity. Results The mean age of the patients was 59.72 ± 17.24 years (minimum [min] = 18, maximum [max] = 96), of which 57.1% were male. The mean T-EAT-10 of patients who had aspiration (PAS > 5) was 25.91 ± 10.31 (min = 1, max = 40) and the mean T-EAT-10 of patients who did not have aspiration (PAS < 6) was 15.70 ± 10.54 (min = 0, max = 40) (P < 0.001). Patients with a T-EAT-10 score higher than 15 were 2.4 times more likely to aspirate. A linear correlation was found between T-EAT-10 and PAS scores of the patients (r = 0.416, P < 0.001). The sensitivity of a T-EAT-10 higher than 15 in detecting aspiration was 81.0% and the specificity was 58.0%. A T-EAT-10 score of higher than 15 has a positive predictive value of 72.0% and a negative predictive value of 69.0%. Conclusion The T-EAT-10 can be used to detect unsafe airway protection in neurology clinics to identify and refer dysphagic patients for further evaluation. PMID:28545185

Mediastinal abscess is a fatal condition, treatment of mediastinal abscess is with antibiotics and sometimes surgery for debridement and drainage. Endobronchial ultrasound-guided transbronchial needle aspiration (EBUS-TBNA) is a safe assessment and candidate treatment method of mediastinal lesions. This study aimed to HYPERLINK "javascript:void(0);" discuss risks and benefits in treatment of mediastinal abscess by EBUS-TBNA. We noticed a 56-year-old man with developed bilateral pneumonia and sepsis after puncture of mediastinal abscess by EBUS-TBNA. The patient was successfully treated with a combination of systemic anti-infection treatment and intracavitary administration of antibiotics, antifungal and repeated drainage and lavage via EBUS-TBNA, in 1 year follow-up without recurrence. This study indicated infection spread risk of mediastinal abscess after EBUS-TBNA, and mediastinal abscess was successfully cured by combination of systemic anti-infection and local intervention through EBUS-TBNA. EBUS-TBNA is a potential effective minimally invasive treatment for mediastinal abscess, and it is necessary to be aware of clinical complications after puncture of mediastinal infectious lesions by EBUS-TBNA. © 2015 John Wiley & Sons Ltd.

The aim of this study was to investigate disability impact in patients and cost to the families of patients who have had complications of transvaginal prolapse mesh kits and underwent surgical revision. Patients who developed complications of transvaginal mesh kits for prolapse and who had undergone vaginal prolapse mesh surgical revision/removal in 2009 to 2014 at a single institution were identified by Current Procedural Terminology codes. The group was invited to complete a phone survey pertaining to the initial vaginal mesh used for prolapse surgery utilizing Sheehan Disability Scale (scale 0-10) and Years of life Lived with Disability (YLDs) questionnaires. The data collected were used to estimate the disability and cost analysis. We used our data to estimate the economic and quality-of-life impact of vaginal mesh complications on patients in the United States RESULTS: Sixty-two patients (62/198 [31.2%]) were consented to participate and completed the questionnaires by phone. Extremely disabled patients were 18 (29%) of 62 of whole cases, and 5 (8%) of 62 reported that they had no disability after vaginal mesh surgery. The median for overall disability score after vaginal mesh procedure was 8 (which reflects marked disability on a scale of 0-10). The majority of patients missed a median of 12 months of their school or work because of their mesh complications. Thirty-seven (59.6%) of 62 did not improve after mesh removal. Twenty-one (33.9%) of 62 stated that their family income dropped because of productivity loss related to mesh complications. The mean time between vaginal mesh surgery and mesh removal procedure was 4.7 years. Sheehan Disability Scale scores are significantly correlated with YLDs outcomes. Patients' overall disability score showed a significant correlation with YLDs scores (P mesh for prolapse reduction complications had a sustained disability impact that continued despite mesh removal. Likewise, the complications were associated with

Thyroid Fine-Needle Aspiration Cytology Practice in Korea

Full Text Available We reviewed the current status of thyroid fine-needle aspiration cytology (FNAC in Korea. Thyroid aspiration biopsy was first introduced in Korea in 1977. Currently, radiologists aspirate the thyroid nodule under the guidance of ultrasonography, and cytologic interpretation is only legally approved when a cytopathologist makes the diagnosis. In 2008, eight thyroid-related societies came together to form the Korean Thyroid Association. The Korean Society for Cytopathology and the endocrine pathology study group of the Korean Society for Pathologists have been updating the cytologic diagnostic guidelines. The Bethesda System for Reporting Thyroid Cytopathology was first introduced in 2009, and has been used by up to 94% of institutions by 2016. The average diagnosis rates are as follows for each category: I (12.4%, II (57.9%, III (10.4%, IV (2.9%, V (3.7%, and VI (12.7%. The malignancy rates in surgical cases are as follows for each category: I (28.7%, II (27.8%, III (50.6%, IV (52.3%, V (90.7%, and VI (100.0%. Liquid-based cytology has been used since 2010, and it was utilized by 68% of institutions in 2016. The categorization of thyroid lesions into “atypia of undetermined significance” or “follicular lesion of undetermined significance” is necessary to draw consensus in our society. Immunocytochemistry for galectin-3 and BRAF is used. Additionally, a molecular test for BRAF in thyroid FNACs is actively used. Core biopsies were performed in only 44% of institutions. Even the institutions that perform core biopsies only perform them for less than 3% of all FNACs. However, only 5% of institutions performed core biopsies up to three times more than FNAC.
