    Full Text Available Summary Due to widespread use of pelvic and transvaginal ultrasound in routine gynecological evaluation, the incidental finding of adnexal masses has led to discussions about management in asymptomatic patients regarding the risk of ovarian cancer. Transvaginal ultrasonography remains the modality of choice in the evaluation of suspicious characteristics. The combined analysis of ultrasound morphological parameters with Doppler study, serum carcinona antigen 125 and investigation of a symptom index may improve diagnosis. Surgical approach should be considered whenever there are suspicious images, rapid growth of cysts, changes in the appearance compared to the initial evaluation or when the patient has symptoms. Future studies on genetic and molecular mechanisms may help explain the pathophysiology of ovarian cancer, improving early diagnosis and treatment.

    A literature review was conducted on radiological detection and characterization of major adnexal masses identified in ultrasound, computerized axial tomography and magnetic resonance. The characteristics, and incidence findings have been identified in imaging methods of benign adnexal masses and most common ovarian neoplasms. The proposed new classification of adnexal masses GI-RADS has been released. The report of adnexal ultrasound images were classified into 5 categories. They have relied on morphological findings and the likelihood of benignity or malignancy, in addition to the radiological staging submit. The purpose has been simplifying the diagnosis and better therapeutic for the patient behavior [es

    Full Text Available BACKGROUND The aim of our study is to evaluate the accuracy of MR imaging in characterisation of adnexal masses. MATERIALS AND METHODS This study was done for a span of 7 months from July 2016 to January 2017. Preoperative MR imaging of the pelvis was performed in 77 women with clinically and sonographically detected adnexal masses. The accuracy of MR imaging in the differentiation between benign and malignant ovarian masses was evaluated using histopathological results as the standard of reference. RESULTS The sensitivity, specificity and accuracy of MR imaging in characterisation of ovarian masses were 95.2%, 98.4% and 97.6%, respectively. CONCLUSION In conclusion, MR imaging is a better diagnostic modality for differentiating and characterising benign and malignant adnexal masses.

  5. Review: Management of adnexal masses: An age-guided approach ...

    African Journals Online (AJOL)

    Adnexal masses in different age groups may need different management approaches. By elimination of the type of mass that is less likely in a specific age group one can identify the most prevalent group which can guide management. Most important of all, the probability of malignancy must either be identified or ruled out.

    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.

    Full Text Available Objective: To evaluate the role of colour Doppler sonography in differentiating between benign and malignant adnexal masses. Materials & Methods: One hundred women diagnosed with adnexal masses underwent colour Doppler sonography. Resistance index (RI and Pulsatility index (PI were calculated in each case and lowest RI and PI obtained at any point in the mass were considered for analysis. Masses which were completely a vascular were considered as benign. Histopathological diagnosis was obtained in each case. Sensitivity, specificity, positive predictive value, negative predictive value and accuracy of colour Doppler were calculated. Results: Mean RI and Mean PI were significantly lower in malignant masses (0.34 & 0.95 respectively as compared to benign masses (0.72 & 1.97 respectively. Out of 81 benign cases, Doppler could correctly diagnose 78 cases as benign, but labelled 3 cases as malignant which were actually benign. Out of 19 malignant cases, 16 cases were correctly diagnosed, whereas 3 cases were missed by Doppler. Our study showed a sensitivity of 84.2%, specificity of 96.3%, positive predictive value of 84.2%, negative predictive value of 96.3% and accuracy of 94% for colour Doppler. Conclusion: Colour Doppler sonography is helpful in differentiating benign from malignant adnexal masses.

    Surgical evaluation of adnexal masses in patients with cervical cancer can be considered in order to optimize treatment outcomes and rule out a second pathologic process. Our objective was to review treatment patterns and outcomes in women with advanced cervical cancer (ACC) and an adnexal mass. A retrospective review was performed with IRB approval of patients treated for advanced cervical cancer at our institution between 1990 and 2011. Patients were identified using institutional databases and tumor registries. Descriptive statistics were performed using Microsoft Excel 2011 and Instat was used to perform Fisher's exact test and student T-tests. Two hundred twenty eight patients with stage IIB-IVB cervical cancer were identified, 50 (22%) of whom had an adnexal mass on initial imaging studies (31 stage IIB, 15 stage IIIB, 3 stage IVA, 3 stage IVB). The mean follow up time of patients with adnexal masses was 22 months (range 3-128 months). Thirteen of 50 (26%) patients underwent surgical evaluation of the adnexal mass. Six were found to have cervical cancer metastatic to the adnexae, while seven had benign adnexal lesions. Thirty-seven of 50 (74%) patients were conservatively managed. All 37 women had cystic masses <8 cm or complex masses <5 cm in size. Thirty-four of the 37 (92%) patients had resolution of their adnexal mass and 3 were deemed stable on follow up imaging. Twenty three percent of surgically managed patients and 57% of conservatively managed patients had disease recurrence (p=0.05). There were no recurrences in the adnexa. Twelve percent of women with ACC and an adnexal mass have ovarian metastases. Patients with cystic masses less than 8 cm and complex masses less than 5 cm in size can be expectantly managed.

    Adnexal masses are formations seen in women of all ages; they most often include cystic elements. Medical history, physical examination, different imaging methods, and tumor marker determinations must be used together for preoperative evaluation of an adnexal mass. Both benign and malignant tumors of the small intestine are more rarely encountered than malignant tumors of other gastrointestinal system components; although advanced imaging methods and other diagnostic techniques are used, they do not always allow these tumors to be differentiated from adnexal masses. We report here on two cases operated on with the preliminary diagnosis of an adnexal mass, in which the presence of a gastrointestinal stromal tumor and a leiomyoma of the ileum, respectively, was established.

    Purpose To evaluate the rate of malignancy in incidentally detected simple adnexal cysts at computed tomography (CT) to determine if simple-appearing cysts require follow-up. Materials and Methods In this HIPAA-compliant, institutional review board-approved retrospective cohort study, an institutional database was searched for abdominal and pelvic CT studies performed between June 2003 and December 2010 in women reported to have adnexal cysts. Adnexal cyst characterization was determined by prospective report description as well as image review by a research fellow and by a fellowship-trained abdominal radiologist for examinations with disagreement between the original report and the research fellow's assessment. Patients with known ovarian cysts or ovarian cancer at time of the index CT examination were excluded. Clinical outcome was assessed by using follow-up imaging studies, medical records, and the state cancer registry. Benign outcome was determined by benign findings at surgery, a decrease in size or resolution of a simple-appearing cyst at follow-up imaging, or stability of the cyst for at least 1 year. Descriptive statistics and 95% confidence intervals (CIs) were calculated. Results Among 42 111 women who underwent abdominal and pelvic CT examinations in the study period, 2763 (6.6%; 95% CI: 6.3%, 6.8%) (mean age, 48.1 years ± 18.1; range, 15-102 years) had a newly detected finding of ovarian cyst described in the body or impression section of the report. Median cyst size was 3.1 cm (range, 0.8-20.0 cm). Eighteen (0.7%; 95% CI: 0.4%, 1.0%) of 2763 patients were found to have ovarian cancer after an average follow-up of 5.1 years ± 3.8 (range, 0-12.8 years). None (95% CI: 0%, 0.4%) of 1031 women with simple-appearing cysts were given a diagnosis of ovarian cancer. This included none (95% CI: 0%, 0.4%) of 904 women with simple-appearing cysts with an adequate reference standard for benign outcome. Conclusion The prevalence of previously unknown adnexal

    An update of the 2010 published ESUR recommendations of MRI of the sonographically indeterminate adnexal mass integrating functional techniques is provided. An algorithmic approach using sagittal T2 and a set of transaxial T1 and T2WI allows categorization of adnexal masses in one of the following three types according to its predominant signal characteristics. T1 'bright' masses due to fat or blood content can be simply and effectively determined using a combination of T1W, T2W and FST1W imaging. When there is concern for a solid component within such a mass, it requires additional assessment as for a complex cystic or cystic-solid mass. For low T2 solid adnexal masses, DWI is now recommended. Such masses with low DWI signal on high b value image (e.g. > b 1000 s/mm{sup 2}) can be regarded as benign. Any other solid adnexal mass, displaying intermediate or high DWI signal, requires further assessment by contrast-enhanced (CE)T1W imaging, ideally with DCE MR, where a type 3 curve is highly predictive of malignancy. For complex cystic or cystic-solid masses, both DWI and CET1W - preferably DCE MRI - is recommended. Characteristic enhancement curves of solid components can discriminate between lesions that are highly likely malignant and highly likely benign. (orig.)

    To compare the diagnostic performance and radiation dose between contrast-enhanced CT (ECT) alone, and combined unenhanced and contrast-enhanced CT (UE + ECT) for the assessment of adnexal mass. This retrospective study was approved by the Institutional Review Board. A total of 146 consecutive patients (mean age, 41.1 years) who underwent preoperative unenhanced and contrast-enhanced multidetector CT of the pelvis and had adnexal masses found at surgery were included. Two readers independently evaluated the likelihood of adnexal malignancy on a 5-point scale on two different imaging datasets (ECT alone and UE + ECT). The area under the receiver operating characteristic curve (AUC) was used to evaluate diagnostic performance. Radiation dose to patients was calculated by the volume CT dose index (CTDIvol) and the dose length products (DLP) on each dataset. Of the total 178 adnexal masses, 133 masses were benign and 45 masses were malignant. For both readers, there is no significant difference of AUC values between ECT alone and UE + ECT for the detection of adnexal malignancy (reader 1, 0.93 vs. 0.95; reader 2, 0.92 vs. 0.91) (p > 0.05). The mean CTDIvol (12.6 ± 2.2 mGy) and DLP (641.2 ± 137.2 mGy) of ECT alone was significantly lower than the mean CTDIvol (21.5 ± 2.7 mGy) and DLP (923.6 ± 158.8 mGy) of UE + ECT (p < 0.0001). The use of unenhanced CT scan in addition to contrast-enhanced CT scan does not improve the detection of adnexal malignancy, but increases radiation exposure.

    Full Text Available We present a case of a 51-year-old woman who suffered from persistent right lower abdominal pain. Ultrasoundexamination revealed two lesions in the area of right adnexa. A suspicion of right adnexal cyst was made. Laparoscopyshowed that patient was affected by an early stage of pseudomyxoma peritonei (PMP resulting from a rupturedmucocele of the vermiform appendix. This condition is very rare, however, due to its localization and not specificclinical manifestation it should be taken into consideration in the differential diagnosis of adnexal masses.

    Full Text Available Background/Aim. Concerning the growth of ovarian carcinoma incidence and bad prognosis for malignant forms, early and precise diagnostics is gaining in importance as a condition for precise and appropriate therapy for ovarian tumor masses. The aim of this study was to analyze pre- and postoperative findings of patients with adnexal masses in order to identify factors which could predict the nature and stage of the tumor prior to surgery. Methods. All patients with adnexal masses who were treated in a 6-month period in the Institute of Obstetrics and Gynecology, Clinical Center of Serbia, (IOG, CCS, Belgrade, had their epidemiologic and gynecologic anamnesis and standard laboratory analyses taken prior to surgery. Also, clinical and ultrasonographic check up of pelvic organs was performed, as well as calculation of body mass index (BMI and risk of malignancy index (RMI. After surgery we analyzed histopathological (HP findings of tumors as a mean of final diagnosis and staging. For statistical analysis, we used SPSS 15 program. Results. Throughout a 6-month period, we examined 81 patients with adnexal masses treated in the IOG CCS. HP findings showed that there were significantly more benign (n = 51 than malignant (n = 30 tumors in all the patients (χ2 = 5.512. The patients with malignant HP findings were significantly older than those with benign adnexal masses (t = 3.362; p = 0.001. Significantly more patients with malignant HP findings were in menopause (p = 0.034. BMI values were highly significantly higher in the patients with malignant adnexal tumors (t = 3.421; p = 0.001. There was a statistically significant positive correlation between HP categories (benign, malignant and RMI categories (low, intermediate and high risk of all the patients (high risk, more malignant HP (Roxy = 0.428; df = 78; p = 0.000. Conclusion. Patients in menopause, especially older ones, with high BMI and RMI should immediately be referred to a tertiary level

    2014-01-01

    Objectives: We compared the indication of laparoscopy for treatment of adnexal masses based on the risk scores and tumor diameters with the indication based on gynecology-oncologists' experience. Methods: This was a prospective study of 174 women who underwent surgery for adnexal tumors (116 laparotomies, 58 laparoscopies). The surgeries begun and completed by laparoscopy, with benign pathologic diagnosis, were considered successful. Laparoscopic surgeries that required conversion to laparotomy, led to a malignant diagnosis, or facilitated cyst rupture were considered failures. Two groups were defined for laparoscopy indication: (1) absence of American College of Obstetrics and Gynecology (ACOG) guideline for referral of high-risk adnexal masses criteria (ACOG negative) associated with 3 different tumor sizes (10, 12, and 14 cm); and (2) Index of Risk of Malignancy (IRM) with cutoffs at 100, 200, and 300, associated with the same 3 tumor sizes. Both groups were compared with the indication based on the surgeon's experience to verify whether the selection based on strict rules would improve the rate of successful laparoscopy. Results: ACOG-negative and tumors ≤10 cm and IRM with a cutoff at 300 points and tumors ≤10cm resulted in the same best performance (78% success = 38/49 laparoscopies). However, compared with the results of the gynecology-oncologists' experience, those were not statistically significant. Discussion: The selection of patients with adnexal mass to laparoscopy by the use of the ACOG guideline or IRM associated with tumor diameter had similar performance as the experience of gynecology-oncologists. Both methods are reproducible and easy to apply to all women with adnexal masses and could be used by general gynecologists to select women for laparoscopic surgery; however, referral to a gynecology-oncologist is advisable when there is any doubt.

    Full Text Available Background. The aim of this retrospective study was to find the incidence and type of adnexal masses in pregnancy, reliability of preoperative ultrasound examination and the effect of the surgical approach used, duration of pregnancy at the time of surgery, and the effect of emergency or planned surgery on the outcome of pregnancy. The obtained results and the data from literature were to provide the basis of the guidelines for the management of pregnant women with adnexal masses.Methods. In the study we enrolled 42 women, who underwent a surgery in pregnancy for adnexal masses. All surgeries were performed at the Department of Obstetrics and Gynecology in the period 1 January 1993–31 August 2000. The course of pregnancy was followed by 28 February 2001. The data were obtained from the records kept at the Department and from the questionnaire sent to the women. Statistical analysis was done using Chi-square test. Statistical significance was set at P ≤ 0.05.Results. We found the incidence of adnexal masses in pregnancy, requiring surgical treatment, to be 1/1034 deliveries. There were 6 (14.3% borderline malignant and malignant ovarian tumours, the incidence being 1/7239 deliveries. Preoperative ultrasound examination was not reliable enough to differentiate neither between benign and malignant adnexal masses, nor between adnexal masses and leiomyomas. Forty-two surgeries were made, 21 by laparoscopy and 21 by laparotomy. The size of removed tumours ranged between 4 and 30 cm (mean 9.4 cm, the most frequent type was mature cystic teratoma (n = 12. There were no differences in the outcome of pregnancy between the laparoscopy and laparotomy approach, between emergency and planned surgery, and between laparotomy performed by the 23rd and after the 23rd gestational week. Hemorrhagic shock due to heterotopic pregnancy lead to 1 spontaneous abortion. There were 2 preterm deliveries in the 37th week, 2 babies had intrauterine growth retardation

    To compare the feasibility and safety of the laparoscopic management of adnexal masses appearing preoperatively benign with those suspicious for malignancy. Retrospective study of 694 women that underwent laparoscopic management of an adnexal mass. Laparoscopic management of an adnexal mass was completed in 678 patients. Six hundred and thirty five patients had benign pathology (91.5%) and 53 (7.6%) had primary ovarian cancers. Sixteen patients (2.3%) were converted to laparotomy; there were 13 intraoperative (1.9%) and 16 postoperative complications (2.3%). Patients divided in 2 groups: benign and borderline/malignant tumors. Patients in the benign group had a higher incidence of ovarian cyst rupture (26% vs. 8.7%, p<0.05). Patients in the borderline/malignant group had a statistically significant higher conversion rate to laparotomy (0.9% vs. 16.9%, p<0.001), postoperative complications (1.9% vs. 12.2%, p<0.05), blood loss, operative time, and duration of hospital stay. The incidence of intraoperative complications was similar between the 2 groups. Laparoscopic management of masses that are suspicious for malignancy or borderline pathology is associated with an increased risk in specific intra-operative and post-operative morbidities in comparison to benign masses. Surgeons should tailor the operative risks with their patients according to the preoperative likelihood of the mass being carcinoma or borderline malignancy.

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

    The aim of this article is to describe the development and implementation of structured reporting of adnexal mass findings on pelvic ultrasound in a large integrated health care delivery system. A structured reporting system that includes standardized terminology for describing adnexal masses on ultrasound was developed by a multidisciplinary team of radiologists, gynecologists, and gynecologic oncologists on the basis of literature review and internal data. The system uses a reporting template that requires radiologists to assign abnormal adnexal masses to one of five possible categories on the basis of standardized criteria: category 0, 1, 2, or 3 for masses 10 cm. Unique predefined hashtags were linked to each category to enable electronic data extraction, and a hard stop feature was installed that prevents reports from being finalized without a category designation. In 2014, after a 3-month pilot study, large-scale implementation was supported by an educational campaign consisting of web-based conferences, e-mail announcements, and local presentations. Clinical management recommendations on the basis of category and other clinical factors were provided in a separate practice resource for clinicians. Analysis of adherence revealed that 93% of the approximately 12,000 reports describing abnormal adnexal masses in 2016 included category designations. Feedback from referring providers via an anonymous survey indicated high levels of satisfaction with reports. Multidisciplinary collaboration and leveraging of technology enabled large-scale implementation of structured reporting with high levels of adherence among radiologists and improved satisfaction among referring providers.

In 54 cases(47 patients), we retrospectively analysed the CT findings of 20 pathologically-proven twenty endometriomas(bilateral in four cases), eight hemorrhagic functional cysts, two tubal ectopic pregnancies, eight tubo-ovarian abscesses(bilateral in two cases), ten serous cystadenomas(bilateral in one case), and six mucinous cystadenomas. Internal attenuation, the hyperdense portion, adhesion, and cul-de-sac obliteration were evaluated by CT scanning. Fourteen endometriomas (70%) showed a hyperdense portion, and in only two of these (10%), was a focal nodular hyperdense portion seen on pre-contrast CT scan(10% sensitivity, 100% specificity). Partial or complete cul-de-sac obliteration was identified in 11 patients(75%), whilehemorrhagic functional cysts showed a hyperdense portion in four cases (50%) and were accompanied by partial cul-de-sac obliteration in two(25%). Two unruptured tubal ectopic pregnancies showed CT findings of unilateral hyperdense cystic masses of more than 60 HU. In all cases, tubo-ovarian abscesses were accompanied by thickening of the uterosacral ligament and deviation of thickened mesosalpinx(anterior deviation in 87.5% of patients). Serous and mucinous cystadenomas showed CT findings of hypodense masses(less than 20 HU) without adhesion or cul-de-sac obliteration, and this was helpful in differentiating cystadenomas from other benign cystic adnexal masses, including endometriomas. The evaluation by CT scanning of benign complex cystic adnexal masses with respect to the hyperdense portion and the presence or asence of cul-de-sac obliteration was usful in differentiating endometriomas from other lesions, and might be helpful in determining the method of treatment for each mass lesion.=20

    Mucocele of the vermiform appendix is a rare entity that may mimic a right-sided adnexal mass. We describe a case of appendiceal mucocele in a 78-year-old woman that was initially misdiagnosed as a potentially malignant right ovarian tumor and briefly review the literature on sonographic features of this entity. It is important to improve preoperative diagnosis so as to prevent rupture of mucocele at surgery, which may lead to pseudomyxoma peritonei, and also to seek intraoperatively for the presence of synchronous colorectal neoplasms.

    We describe the imaging features of a tailgut cyst mistaken for an adnexal mass. A pelvic ultrasound in a 28-year-old woman showed a 10-cm hypoechoic left pelvic mass. Having not seen the left ovary, the radiologist concluded that the mass was an endometrioma. CT disclosed a retrorectal cystic lesion with wall calcifications and internal septa. MR confirmed the extra-ovarian location of the tumor, which was hyperintense on T2-weighted images and had an intermediate signal on T1-weighted images. Surgery revealed a retrorectal cystic hamartoma. Radiological diagnosis of a tailgut cyst requires first correct localization of the tumor and then differentiation from other retrorectal masses.

    A 68-year-old female presented to the Gynecologic Oncology Clinic with a right-lower quadrant abdominal mass 3 × 4 cm in diameter palpable on pelvic examination. Her routine laboratory tests were normal. Transvaginal ultrasonography revealed a cystic mass in the right adnexa 3.9 cm in diameter, which was thought to arise in the ovary. At the time of laparoscopy, a 3 × 4 cm tumor arising from the distal end of the appendix was noted. A laparoscopic appendectomy with tumor removal was performed. Histologic examination of the surgical specimen revealed a mucocele of the appendix (AM). Although rare, this tumor should be considered in the differential diagnosis of a right adnexal mass. These tumors can be identified laparoscopically and removed by minimally invasive surgery.

    Full Text Available A 79-year-old female was referred to our Gynecologic Department presenting with a pelvic magnetic resonance imaging (MRI, showing an adnexal mass, later confirmed at the pelvic examination. The patient’s routine laboratory tests were normal. A sonographic examination was performed with inconclusive results. Although the ultrasonography excluded the presence of vascularization and malignant degeneration, the adnexal localization appeared to be dubious. The laparoscopy and the subsequent histologic examination revealed the presence of a mucocele of the appendix. The following case report focuses the attention on a misdiagnosis of appendiceal mucocele. The misdiagnosis caused no negative impact on the treatment that in this case was adequate and successful.

    Full Text Available To develop a tool for individualized risk estimation of presence of cancer in women with adnexal masses, and to assess the added value of plasma fibrinogen.We performed a retrospective analysis of a prospectively maintained database of 906 patients with adnexal masses who underwent cystectomy or oophorectomy. Uni- and multivariate logistic regression analyses including pre-operative plasma fibrinogen levels and established predictors were performed. A nomogram was generated to predict the probability of ovarian cancer. Internal validation with split-sample analysis was performed. Decision curve analysis (DCA was then used to evaluate the clinical net benefit of the prediction model.Ovarian cancer including borderline tumours was found in 241 (26.6% patients. In multivariate analysis, elevated plasma fibrinogen, elevated CA-125, suspicion for malignancy on ultrasound, and postmenopausal status were associated with ovarian cancer and formed the basis for the nomogram. The overall predictive accuracy of the model, as measured by AUC, was 0.91 (95% CI 0.87-0.94. DCA revealed a net benefit for using this model for predicting ovarian cancer presence compared to a strategy of treat all or treat none.We confirmed the value of plasma fibrinogen as a strong predictor for ovarian cancer in a large cohort of patients with adnexal masses. We developed a highly accurate multivariable model to help in the clinical decision-making regarding the presence of ovarian cancer. This model provided net benefit for a wide range of threshold probabilities. External validation is needed before a recommendation for its use in routine practice can be given.

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

    Full Text Available Intrarenal splenosis is very rare and its management is not well established. We present a patient in whom an enhancing left renal mass was incidentally detected on a Computerized tomographic (CT scan, concerning for renal cell carcinoma. However, the lesion was determined to represent intrarenal splenosis, confirmed by Technetium-99m (99mTc sulfur colloid scan and percutaneous biopsy, which revealed splenic tissue. This multimodal approach to diagnosis of an unusual condition spared the patient an invasive procedure.

    Full Text Available The number of patients living with end-stage renal disease (ESRD is increasing in our country and demand for renal grafts is ever increasing. Cadaver renal transplantation is being established as a viable supplement to live transplantation. We present a case where a mass lesion was encountered in the donor kidney from a cadaver. Enucleation of the lesion was done and we proceeded with the grafting. Histopathological examination showed a ′Renomedullary interstitial cell tumour′, a rare benign lesion. Post transplant, the renal function recovered well and the patient is asymptomatic. Such incidental renal masses present an ethical dilemma to the operating surgeon.

  17. Uncommon Implantation Sites of Ectopic Pregnancy: Thinking beyond the Complex Adnexal Mass.

    Ectopic pregnancy occurs when implantation of the blastocyst takes place in a site other than the endometrium of the uterine cavity. Uncommon implantation sites of ectopic pregnancy include the cervix, interstitial segment of the fallopian tube, scar from a prior cesarean delivery, uterine myometrium, ovary, and peritoneal cavity. Heterotopic and twin ectopic pregnancies are other rare manifestations. Ultrasonography (US) plays a central role in diagnosis of uncommon ectopic pregnancies. US features of an interstitial ectopic pregnancy include an echogenic interstitial line and abnormal bulging of the myometrial contour. A gestational sac that is located below the internal os of the cervix and that contains an embryo with a fetal heartbeat is indicative of a cervical ectopic pregnancy. In a cesarean scar ectopic pregnancy, the gestational sac is implanted in the anterior lower uterine segment at the site of the cesarean scar, with thinning of the myometrium seen anterior to the gestational sac. An intramural gestational sac implants in the uterine myometrium, separate from the uterine cavity and fallopian tubes. In an ovarian ectopic pregnancy, a gestational sac with a thick hyperechoic circumferential rim is located in or on the ovarian parenchyma. An intraperitoneal gestational sac is present in an abdominal ectopic pregnancy. Intra- and extrauterine gestational sacs are seen in a heterotopic pregnancy. Two adnexal heartbeats suggest a live twin ectopic pregnancy. Recognition of the specific US features will help radiologists diagnose these uncommon types of ectopic pregnancy. (©)RSNA, 2015.

    To compare the outcome of robotic-assisted laparoscopy vs conventional laparoscopy in the management of ovarian masses. Retrospective cohort (Canadian Task Force classification II-3). Academic medical centre in the northeast United States. Retrospective medical record review of 71 consecutive patients with presumed benign ovarian masses. Robotic-assisted laparoscopy in 30 patients with presumed benign ovarian masses was compared with conventional laparoscopy in 41 patients. Operative outcomes including operative time, estimated blood loss, length of hospital stay, and complications were recorded. Standard statistical analysis was used to compare the outcomes in the 2 groups. Mean (SD) operative time in the robotic group was 1.95 (0.63) hours, which was significantly longer than in the conventional laparoscopic group, 1.28 (0.83) hours (p = .04). Estimated blood loss in the robotic group was 74.52 (56.23) mL, which was not significantly different from that in the conventional laparoscopic group, 55.97 (49.18) mL. There were no significant differences in length of hospital stay between the robotic and conventional laparoscopic groups: 1.20 (0.78) days and 1.48 (0.63). Conversion to laparotomy was not necessary in either group of patients. Intraoperative and postoperative complications were similar between the 2 groups. Robotic-assisted laparoscopy is a safe and efficient technique for management of various types of ovarian masses. However, conventional laparoscopy is preferred for management of ovarian masses because of shorter operative time. Prospective studies are needed to evaluate the outcomes of robotic-assisted laparoscopic management of benign and malignant ovarian neoplasms. Copyright © 2014 AAGL. Published by Elsevier Inc.

    Full Text Available Microcystic adnexal carcinoma (MAC is an uncommon skin neoplasm with a predilection location around the lips. It is characterized by cords and nests of neoplastic cells forming ductular or glandular structures that are embedded in dense collagenous stroma. An eighty-seven year old Caucasian female patient presented with a painless, slowly enlarging mass measuring 3.3 x 2.7 x 1.0 cm on the lower lip for approximately 6 months. The patient underwent 2 fine needle aspiration biopsies (FNAs. Smears made from both FNAs demonstrated similar features including low cellular smears, three dimensional cell clusters forming a glandular structure, round to oval cells with high N:C ratio, occasional cytoplasmic lumens, without distinct hyperchromasia, focal inconspicuous nucleoli, smooth regular nuclear membranes, abundant naked nuclei, occasional squamoid cells and focal acellular stromal fragments in the background. The cytologic differential diagnosis included skin adnexal carcinoma and low grade mucoepidermoid carcinoma arising in the minor salivary gland. The mass was subsequently excised. The diagnosis of microcystic adnexal carcinoma was made. We report cytologic features of MAC and also suggest that MAC can possibly be diagnosed by FNA with the appropriate clinical vignette and immunohistochemical profile..

  3. Incidental breast masses detected by computed tomography: are any imaging features predictive of malignancy?

    2009-05-15

    Aim: To review the outcome of further assessment of breast abnormalities detected incidentally by multidetector computed tomography (MDCT) and to determine whether any MDCT imaging features were predictive of malignancy. Material and methods: The outcome of 34 patients referred to the Primrose Breast Care Unit with breast abnormalities detected incidentally using MDCT was prospectively recorded. Women with a known diagnosis of breast cancer were excluded. CT imaging features and histological diagnoses were recorded and the correlation assessed using Fisher's exact test. Results: Of the 34 referred patients a malignant diagnosis was noted in 11 (32%). There were 10 breast malignancies (seven invasive ductal carcinomas, one invasive lobular carcinoma, two metastatic lesions) and one axillary lymphoma. CT features suggestive of breast malignancy were spiculation [6/10 (60%) versus 0/24 (0%) p = 0.0002] and associated axillary lymphadenopathy [3/10 (33%) versus 0/20 (0%) p = 0.030]. Conversely, a well-defined mass was suggestive of benign disease [10/24 (42%) versus 0/10 (0%); p = 0.015]. Associated calcification, ill-definition, heterogeneity, size, and multiplicity of lesions were not useful discriminating CT features. There was a non-significant trend for lesions in involuted breasts to be more frequently malignant than in dense breasts [6/14 (43%) versus 4/20 (20%) p = 0.11]. Conclusion: In the present series there was a significant rate (32%) of malignancy in patients referred to the breast clinic with CT-detected incidental breast lesions. The CT features of spiculation or axillary lymphadenopathy are strongly suggestive of malignancy.

  4. Unusual cause of acute abdominal pain in a postmenopausal woman: adnexal torsion

    2016-03-01

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

    2011-01-01

    Full Text Available During abdominal ultrasonography of a 37-year-old man a 3.2 cm hypoechoic mass in the right hepatic lobe was found incidentally. This prompted an abdominal CT, an FDG PET/CT, and an angiography to evaluate the nature of the mass. Laboratory data showed positive anti-HBs/anti-HBe, and negative HCV antibody. The alfa-fetoprotein and liver function tests were within normal limits. Contrast-enhanced CT found an enhanced hepatic tumor and primary hepatocellular carcinoma was suspected. PET/CT revealed no abnormal FDG accumulation in the right hepatic mass. The digital subtraction angiographies of the right inferior phrenic artery and right renal artery revealed a hypervascular tumor in the right adrenal gland. Therefore, a diagnosis of a right adrenal tumor was made. Serum aldosterone, serum cortisol, and urine vanillylmandelic acid, and catecholamine were all within normal limits. Laparoscopic right adrenalectomy was performed and adrenal cortical adenoma was diagnosed on a histological study.

    To determine whether intravenous contrast ultrasound examination is superior to gray-scale or power Doppler ultrasound for discrimination between benign and malignant adnexal masses with complex ultrasound morphology. In an international multicenter study, 134 patients with an ovarian mass with solid components or a multilocular cyst with more than 10 cyst locules, underwent a standardized transvaginal ultrasound examination followed by contrast examination using the contrast-tuned imaging technique and intravenous injection of the contrast medium SonoVue(R). Time intensity curves were constructed, and peak intensity, area under the intensity curve, time to peak, sharpness and half wash-out time were calculated. The sensitivity and specificity with regard to malignancy were calculated and receiver-operating characteristics (ROC) curves were drawn for gray-scale, power Doppler and contrast variables and for pattern recognition (subjective assignment of a certainly benign, probably benign, uncertain or malignant diagnosis, using gray-scale and power Doppler ultrasound findings). The gold standard was the histological diagnosis of the surgically removed tumors. After exclusions (surgical removal of the mass > 3 months after the ultrasound examination, technical problems), 72 adnexal masses with solid components were used in our statistical analyses. The values for peak contrast signal intensity and area under the contrast signal intensity curve in malignant tumors were significantly higher than those in borderline tumors and benign tumors, while those for the benign and borderline tumors were similar. The area under the ROC curve of the best contrast variable with regard to diagnosing borderline or invasive malignancy (0.84) was larger than that of the best gray-scale (0.75) and power Doppler ultrasound variable (0.79) but smaller than that of pattern recognition (0.93). Findings on ultrasound contrast examination differed between benign and malignant tumors but there

    In this report, we describe the incidental finding of an oropharyngeal mass in a patient who presented with a chief complaint of temporomandibular pain. The patient was initially evaluated by an otorhinolaryngologist for complaints of headaches, earache, and sinus congestion. Due to worsening headaches and trismus, he was further referred for the management of temporomandibular disorder. The clinical evaluation was uneventful except for limited mouth opening (trismus). An advanced radiological evaluation using magnetic resonance imaging revealed a mass in the nasopharyngeal/oropharyngeal region. The mass occupied the masticatory space and extended superioinferiorly from the skull base to the mandible. A diagnostic biopsy of the lesion revealed a long-standing human papilloma virus (HPV-16)-positive squamous cell carcinoma of the oropharynx. This case illustrates the need for the timely radiological evaluation of seemingly innocuous orofacial pain.

    Nonpalpable testicular masses are usually diagnosed during routine ultrasonography (US) examinations for other conditions. There are conflicting results on the final diagnosis and management of these lesions. In the present study we report the results of a large US series of 5104 patients on nonpalpable testicular masses and discuss the management of these patients. This retrospective observational study was performed in a secondary care military hospital. A total of 5104 patients underwent a US and 11 of them were diagnosed as having a nonpalpable testicular mass. These 11 patients also underwent magnetic resonance imaging (MRI). Two of them refused surgery and were excluded from the study. The remaining nine patients underwent intraoperative US-guided localization and excisional biopsy of the non-palpable testicular parenchymal mass. A radical orchiectomy was required in all of them. US and MRI findings, frozen and final pathology results were recorded. The median age of study subjects was 24 years. The final pathology revealed a malign tumor in eight patients and an inflammatory mass in one patient. There were inconsistent results in four patients between frozen section analysis and final pathology. MRI improved the definition of the solid masses in all patients. MRI enhances the certainty of the diagnosis of malignity in nonpalpable testicular masses, particularly in conditions that generally can not be diagnosed with ultrasonography alone. Frozen section analysis is not an accredited method in diagnosing malign lesions in non-palpable testicular masses. (author)

    Purpose: The aim of this study was to compare CT findings of adrenal incidentalomas with a definitive histological diagnosis in order to establish CT features characteristic for individual types of lesions. Patients and methods: The retrospective study comprised of patients with adrenal lesions detected on abdominal CT. The patients with these incidental findings subsequently underwent adrenalectomy. The adrenalectomy was followed by a histological assessment of the expansion process. The study consisted of 62 adrenal expansions found in 55 patients (in seven patients bilateral lesions were found). According to the definitive histological diagnosis after adrenalectomy, the lesions were divided into the following six groups: primary adrenocortical carcinoma (n = 4), metastasis (n = 7), adrenocortical adenoma (n = 37), pheochromocytoma (n = 9), myelolipoma (n = 2), and others (n = 3). CT observations were categorized as follows: size, shape, margins, density, side of the expansion, homogeneous or heterogeneous density before and after contrast application, presence of central hypodensity, presence of central calcifications and fat deposits. Statistical analysis was carried out using the χ 2 -test, Kruskal-Wallis test and Mann-Whitney test. To estimate the differences between the subgroups, the t-test was used. For the evaluation of the mutual relations of maximum size, mean size, and volume, regression analysis (coefficient of determination R 2 ) was used. Results: The correlation and regression analysis suggest that there will be no statistically significant error if the maximum size measurements are used instead of the mean size or volume measurements of the lesion. Sensitivity, specificity, accuracy, positive predictive value, negative predictive value for distinguishing adenomas and non-adenomas using a cut-off diameter of 41.5 mm were 81.1%, 70.0%, 77.2%, 83.3%, 66.7%, respectively; using the non-contrast density threshold of 23 HU, they were 89.2%, 100%, 93

    Full Text Available Thromboembolism occurs commonly in general practice and leads to significant health burden. Apart from cardiac sources, aortic atherosclerotic plaques contribute considerably to thromboembolism. A 63-year-old diabetic hypertensive woman referred to our center due to exertional chest pain unresponsive to optimal medical therapy and underwent coronary angiography. Owing to resistance during guide-wire advancement, an aortography was performed. Aortic arch injection demonstrated a large suspended mass distal to the left subclavian artery with free movement in the descending thoracic aorta. Echocardiography revealed widespread atherosclerotic changes in the aortic arch with a large hypermobile mass. Dual-source multi-slice (2 × 128:256 computed tomography angiography of the whole aorta revealed a large floating mass (in favor of a thrombus in the distal portion of the arch. The patient underwent coronary artery bypass grafting due to severe coronary artery disease. The intra-aortic mass, which was actually a large atherosclerotic plaque, was resected at the same session. She was discharged uneventfully and during a 1-year follow-up, she had no embolic events.

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

    Full Text Available Victoria Mary Lendrum CohenSt. Bartholomew’s and Moorfields Eye Hospital, London UKAbstract: Most lymphomas that involve the ocular adnexal structure are low grade, B cell, non-Hodgkin’s lymphomas. The treatment depends upon the grade and stage of the disease. High grade lymhoma requires treatment with systemic chemotherapy whereas the localized low grade (extranodal marginal zone lymphoma can be successfully managed with local radiotherapy. Chlamydia psittaci infection is associated with low grade ocular lymphoma; however there is wide geographic variation in the strength of this association. Blanket antibiotic therapy is not advised unless there is proof of an infective agent. The monoclonal antibody, rituximab, may be successful for CD20 positive lymphoma, although it is likely that rituximab will have better long-term results when used in combination with systemic chemotherapy.Keywords: ocular adnexal lymphoma, mucosa associated lymphoid tissue, extranodal marginal zone lymphoma, Chlamydia psittaci, rituximab, radiotherapy, chemotherapy

    Caseous calcification of mitral annulus is rather rare echocardiographic finding with prevalence of 0.6% in pts. with proven mitral annular calcification and 0.06% to 0.07% in large series of subjects in all ages. Echocardiographic images of caseous calcification are often heterogenous due to calcium and lipid deposits, and the masses show hyperechogenic and hypoechogenic areas. However the appearance of caseous calcification can imitate that of abscess, tumors and cysts, surgical treatment may not be needed when there is no obstruction. 76-year old obese (BMI 32 kg/m 2 ), female patient with history of hypertension, stable coronary artery disease, diabetes type 2 and hyperlipidemia presented with no symptoms of mitral valve dysfunction and had no abnormalities on physical exam. Transesophageal echocardiography identified well-organized, composite, immobile lesion (22×15 mm) localized in the posterior part of the mitral annulus, with markedly calcified margins, and no significant impact on the valve function. In computed tomography (CT) lesion was described as calcified (24×22×17.5 mm), connected with posterior leaflet and posterior part of the mitral annulus, reducing posterior leaflet mobility. CT brought the suggestion of caseous mitral annular calcification. Coming to a conclusion, bearing in mind no mitral valve dysfunction at that time, patient was offered conservative treatment. Although caseous mitral annular calcification is typically an incidental finding, accurate recognition is needed to avoid mistaking the lesion for a tumor or abscess, which may result in unnecessary cardiac surgery. However this entity is diagnosed on cardiac MRI, multi-modality imaging, especially non-contrast CT, allows for the confident, prospective diagnosis

    Surface area was estimated by three different methods using number and/or mass concentrations obtained from either two or three instruments that are commonly used in the field. The estimated surface area concentrations were compared with reference surface area concentrations (SAREF) calculated from the particle size distributions obtained from a scanning mobility particle sizer and an optical particle counter (OPC). The first estimation method (SAPSD) used particle size distribution measured by a condensation particle counter (CPC) and an OPC. The second method (SAINV1) used an inversion routine based on PM1.0, PM2.5, and number concentrations to reconstruct assumed lognormal size distributions by minimizing the difference between measurements and calculated values. The third method (SAINV2) utilized a simpler inversion method that used PM1.0 and number concentrations to construct a lognormal size distribution with an assumed value of geometric standard deviation. All estimated surface area concentrations were calculated from the reconstructed size distributions. These methods were evaluated using particle measurements obtained in a restaurant, an aluminum die-casting factory, and a diesel engine laboratory. SAPSD was 0.7-1.8 times higher and SAINV1 and SAINV2 were 2.2-8 times higher than SAREF in the restaurant and diesel engine laboratory. In the die casting facility, all estimated surface area concentrations were lower than SAREF. However, the estimated surface area concentration using all three methods had qualitatively similar exposure trends and rankings to those using SAREF within a workplace. This study suggests that surface area concentration estimation based on particle size distribution (SAPSD) is a more accurate and convenient method to estimate surface area concentrations than estimation methods using inversion routines and may be feasible to use for classifying exposure groups and identifying exposure trends.

    Pheochromocytoma accounts for approximately 25% of incidentally discovered adrenal masses. Certain diagnostic procedures (e.g., adrenal arteriography, needle biopsy of an adrenal mass), anesthesia and abdominal surgery may cause a sudden release of catecholamines from a pheochromocytoma and induce paroxysmal attacks of hypertension. In addition, pheochromocytoma is well known to cause unsuspected operating room deaths. Therefore, we must carefully separate this functioning neoplasm from other types of adrenal masses. In this study, we compared the results of noninvasive tests including assay of urinary catecholamines and their metabolites, a provocative pharmacologic test using metoclopramide (MCP test), and {sup 131}I-metaiodobenzylguanidine (MlBG) scintigraphy to screen for pheochromocytoma in 10 consecutive patients with an incidentally discovered adrenal mass (6 pheochromocytomas and 4 non-functioning adrenocortical adenomas). We measured the 24-hour urinary excretion of catecholamines, metanephrines and vanillyl mandelic acid in all 10 patients; 5 were positive, 4 were negative and 1 was false-negative (sensitivity=83%, specificity=100%). The MCP test was performed in 7 patients; 3 were positive, 3 were negative and 1 was false-negative (sensitivity=75%, specificity=100%). MIBG scintigraphy was performed in 7 patients; 4 were positive, 1 was negative and 2 were false-negative (sensitivity=67%, specificity=100%). According to these results, all patients with an incidentally discovered adrenal mass should undergo a determination of the 24-hour urinary excretion of catecholamines and their metabolites, including metanephrines. If this urine assay is negative, other noninvasive tests including the MCP test and MIBG scintigraphy should be considered in selected patients with radiographic characteristics of pheochromocytoma.

Retrospective cohort study. Tertiary care children's hospital. Patients ages 6-21 years who underwent surgical management for benign adnexal lesions. Comparison of surgery times, size of lesions, pain scores, and patient length of stay after minilaparotomy vs laparoscopy. Forty-four patients were identified. Of those, 59% (n = 26) had a laparoscopic procedure and 41% (n = 18) underwent minilaparotomy. Patients who underwent minilaparotomy were more likely to have a larger adnexal mass than those in the laparoscopy group with a median size of 15.5 cm vs 6.0 cm, respectively (P laparoscopy. The minilaparotomy approach should be considered when laparoscopy is limited. Copyright © 2017 North American Society for Pediatric and Adolescent Gynecology. Published by Elsevier Inc.

    The purpose of the diagnostic evaluation of adnexal tumours is to exclude the possibility of malignancy. The malignancy risk index II identifies patients at high risk for ovarian cancer. The cut-off value is greater than 200. To evaluate the diagnostic accuracy of malignancy risk index II in post-menopausal women with adnexal tumours in relation to the histopathological results. A total of 138 women with an adnexal mass were studied. The malignancy risk index II was determined in all of them. They were divided into two groups according to the histopathology results; 69 patients with benign tumours and 69 patients with malignant tumours. A diagnostic test type analysis was performed with respect to the results of malignancy risk index II ≤ 200 or greater than this. The percentages and 95% confidence intervals were calculated. The accuracy was 81.8% (75.5-88.3), sensitivity 76.8% (66.9-86.7), specificity 87% (79.1-94.9), with a positive predictive value of 85.5% (76.7-94.3), and a negative predictive value of 78.9% (69.7-88.1). The positive likelihood ratio was 590, and the negative likelihood ratio was 0.266. The malignancy risk index II has good performance in the proper classification of post-menopausal women with adnexal masses, both benign and malignant, with an accuracy of 81.8%.

    This article shows the experience in 61 patients with adnexal tumors studied from June 1988 to June 1994; the origin of the patients in private and semiprivate, to whom we practiced a diagnostic and operative laparoscopy (56/61) at the same time. The inclusion and exclusion criteria were determined by clinical history (past history, age, symptoms, size, etc.), vaginal ultrasonography scan (ascites, papillas, cyst's content, etc.), laboratory tests (Ca 125 in postmenopausal patients), the macroscopic assessment during the diagnostic laparoscopy, transoperative biopsy (19/61) was made in order to confirm the benign findings seen before laparoscopy; and the results were accordingly on the 61 cases. The cause of consult was infertility in 24/61; 18/61 were primary infertility; 6/61 were secondary infertility. We did 22 cystectomies and 2 oophorectomies; 10 of them became pregnant. 37 from 61 had pain, nine of this group we did an oophorectomy (2 by torsion, 3 had hemorrhagic cysts that were ruptured and 4 were residual ovary), the rest 28 we performed cystectomy with frank improvement of their symptoms. The postoperative diagnosis of the tumors were: luteomas 13/61; functional cysts 17/61, Hemorrhagic cysts 8/61; endometriomas 9/61; serous cystoadenoma 3/61; mucinous cystoadenoma 1/61; ovaric fibroma 1/61; mature cystic teratoma 2/61; residual ovaries 4/61; paraovaric cysts 2/61 and Morgagni's hydatide 1/61. It is concluded that if one follows all the correct parameters for the evaluation of adnexal tumors, the endoscopic procedure could be safe with the benefits of the laparoscopic procedure.

    Thyroid cancer may be clinically evident as a tumor mass in the neck or as a histopathological incidental finding after thyroid surgery for an apparent benign condition. Our objective was to assess the differences in clinical signs, surgical management, and course between incidental and clinically diagnosed thyroid tumors. A retrospective study was conducted on patients operated on for benign or malignant thyroid disease from January 2000 to March 2014. Among the 1415 patients who underwent any thyroid surgery, 264 neoplasms were found, of which 170 were incidental. A comparison was made of incidental versus non-incidental carcinomas. Among incidental carcinomas, cases whose indication for surgery was Graves' disease were compared to those with multinodular goiter. Incidental carcinomas were in earlier stages and required less aggressive surgery. There were no differences in surgical complications between incidental and clinical tumors, but mortality and relapses were markedly higher in non-incidental cancers (4.4% vs 0% and 13.2% vs 4.8% respectively). Carcinomas developing on Graves' disease showed no differences from all other incidental tumors in terms of complications, mortality, or relapse after surgery. Early stage thyroid cancer has better survival and prognosis after surgical treatment. Copyright © 2016 SEEN. Publicado por Elsevier España, S.L.U. All rights reserved.

    46 patients with benign (n=42) and malignant (n=4) cystic adnexal tumours underwent MRI of the pelvis. Transaxial and coronal images were acquired using conventional T 1 - and T 2 -weighted SE-sequences after oral administration of superparamagnetic iron oxide particles (Ferristene). Additional T 1 -weighted SE-images were obtained immediately following gadoliamide (Gd DTPA-BMA) injection. MRI correctly classified the four malignant lesions, whereas nine histologically benign lesions were misdiagnosed as malignant. Intravenous contrast yielded a superior delineation of intratumoural architecture. Due to exclusion of solid structures, MRI with oral and i.v. contrast enables to dismiss suspected malignity in cystic adnexal lesions. Because of the non-specificity of the macroscopic criteria of dignity, the MR diagnosis 'malignity' is of limited value. (orig./MG) [de

    To our knowledge, the clinical features of ocular adnexal mantle-cell lymphoma (OA-MCL) have not previously been evaluated in a large multicenter cohort. To characterize the clinical features of OA-MCL. This retrospective multicenter study included patient data collected from January 1, 1980, through December 31, 2015, at 6 eye cancer centers in 4 countries. Medical records of 55 patients with OA-MCL were reviewed; the median length of follow-up was 33 months. Overall survival, disease-specific survival, and progression-free survival were the primary end points. Fifty-five patients were included; ocular adnexal MCL was found to be most common in older individuals (mean age, 70 years) and men (n = 42 of 55; 76%). Patients with OA-MCL frequently presented with disseminated lymphoma (n = 34 of 55; 62%), and were likely to experience stage IVE disease (n = 35 of 55; 64%), with bilateral involvement (n = 27 of 55; 47%), tumor masses (n = 27 of 36; 75%), and involvement of the orbit (n = 32 of 55; 58%). Chemotherapy with or without external beam radiation therapy was the most frequently used treatment. Overall survival rates for the entire cohort were 65% at 3 years (95% CI, 52%-78%) and 34% at 5 years (95% CI, 21%-47%). Disease-specific survival after 5 years was 38% for the entire cohort (95% CI, 25%-51%); the disease-specific survival adjusted by eye cancer center was better in patients who had received rituximab in addition to the chemotherapy regimen (hazard ratio, 3.3; 95% CI, 1.0-14.7; P = .06). The median progression-free survival was 2.3 years (95% CI, 1.8-2.7 years) in patients who experienced recurrence after primary treatment, and 4.1 years (95% CI, 3.9-4.3 years) in patients who presented with a relapse of systemic lymphoma in the ocular adnexal region. These results suggest that the distinctive features of OA-MCL are its appearance in older male individuals, advanced stage and bilateral manifestation at the time of diagnosis, and

    The purpose of this investigation was to estimate radiation-absorbed dose in orbital tumors from yttrium-90 ibritumomab tiuxetan (Zevalin) radioimmunotherapy of ocular adnexal lymphoma. Three patients participating in a prospective research protocol involving treatment of ocular adnexal lymphoma with yttrium-90 Zevalin consented to quantitative radionuclide imaging to estimate tumor radiation-absorbed doses. Each patient received 185 MBq of indium-111 Zevalin, followed by serial planar whole-body scanning, to derive an activity versus time curve for the tumor. Single photon emission computed tomography (SPECT) and computed tomography (CT) imaging, including a calibration source, were performed at 24 h on a SPECT/CT scanner, to obtain a SPECT estimate of the radioactivity (in megabequerels) in the tumor and correct the planar curve, as well as estimate the tumor mass (M) from CT. The curve was then converted to that for yttrium-90 at the prescribed activity, and absorbed dose estimated from the area under the curve multiplied by the Medical Internal Radiation Dose S value (Gy per MBq-h) for a sphere of mass M. A right orbital tumor in one patient was visualized in both the planar and SPECT/CT images, with an estimated absorbed dose of 3.57 Gy. Tumor uptake in the other two patients was not visualized. The radiation dose to the orbit and ocular structures during radioimmunotherapy of ocular adnexal lymphoma is well below the threshold for significant radiation-induced ocular toxicity and about 10 times lower than that delivered during external beam radiotherapy.

    Full Text Available Background/Aim. The glycoprotein of a high molecular weight CA-125, which is not a specific tumor marker of ovarian cancer, is secreted by the endothelial cells of most pelvic organs. Endometriosis, inflammatory processes in the pelvic cavity, as well as some nongynecoligical malignant diseases, could be followed by the increased values of CA-125. Serial assessment of the values of CA- 125 makes it possible to avoid surgical treatment, and, by means of the used conservative treatment, to avoid malignant diseases not to be noticed. Methods. The study included 57 female patients hospitalized due to inflammable adnexal tumors. Besides following the values of serum CA-125 during and after the therapy, also performed were the transvaginal Doppler ultrasonography and the determination of the values of resistance index (RI. Results. In 27 patients (55.1% the CA-125 values ranged from 38.8 U/ml to 794 U/ml, while in 30 of the patients they were within the range of normal. In this group of the patients, besides the increased values of CA- 125, also increased were the values of leucocytes (119/l − 209/l, as well as the sedimentation rates (65−120 within the first hour. In all the 57 patients, transvaginal Doppler ultrasonography revealed the presence of adnexal tumor of inflammatory kind. The measured values of RI were within the range of 0.539−0.681. Eight of the patients were treated by the conservative - triple antibiotic therapy, while in 49 patients explorative laparotomy was performed. Hystorectomy was done in 12 of the patients, and one-side adnexectomy in 37 of them. Conclusion. The method for the assessment of CA-125 is simple and available which facilitates the monitoring of surgical, conservative or the combined therapy that is particularly significant in younger patients with inflammable adnexal tumor developed on the basis of endometrosis.

    Full Text Available Myxomas are mesenchymal tumors commonly found in the heart and skin. Renal myxomas are rare, having only been documented 14 times. Our case is a 55-year-old woman who presented to our clinic after a right renal mass was incidentally found on CT. Evaluation with MRI showed a mass that appeared to arise from the supero-medial cortex of the right kidney. As the imaging was concerning for renal cell carcinoma, the patient underwent a partial nephrectomy. Microscopic examination showed a well-circumscribed mass with polygonal to spindle-shaped cells in a granular eosinophilic cytoplasm. Immunohistochemical staining for CD-10, Desmin, HMB-45, and Pankeratin were negative.

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

    A ten-year-old girl presented with four days of lower abdominal pain. A diagnostic laparoscopy on the suspicion of acute appendicitis revealed left-sided adnexal torsion. The cyanotic ovary was detorsed and recovered. At three-month follow-up there were no clinical or ultrasonic signs of pathology....... The clinical presentation of adnexal torsion is unspecific and mimics several differential diagnosis. Adnexal torsion is a rare condition, especially in pre-pubertal girls. However, it must still be kept in mind when evaluating girls regardless of age with lower abdominal pain....

    Full Text Available We present a rare distinctive variant of invasive carcinoma of breast characterized by adnexal differentiation of tumor of trichoblastic type. The neoplasm was identified in a mastectomy specimen from an 83-year-old Chinese woman. Morphologically, the trichoblastic differentiation was characterized by the formation of solid sheets and nests of basaloid cells. The tumor cells were positive for cytokeratin 5/6, BER-EP4, bcl-2, and beta-catenin. Stromal cells were positive for CD10. The tumor cells exhibited a and ldquo;triple negative and rdquo; profile; the nuclei did not react with antibodies to estrogen and progesterone receptors but failed to show overexpression of the HER2/neu protein. The MIB-1 labeling index averaged 20%. It is hoped that this case increases awareness for this unique morphological variant of invasive ductal carcinoma.

    Full Text Available Introduction: Laparoendoscopic single-site surgery (LESS is an emerging technique in gynaecology. The proposed advantages of the LESS include better cosmesis and reduction in pain. We report our preliminary experience with LESS in the treatment of adnexal pathology. Materials and Methods: After a preoperative workup, LESS was offered to 37 patients between July 2009 and April 2015. All the procedures were carried out through a 2–2.5 cm transumbilical incision using conventional laparoscopic instruments. A single-incision, multiport (SIMP approach (utilising one 7 mm and two 5 mm ports was used in 27 patients and a homemade glove port (HMGP was utilised in ten patients. All the specimens were extracted after placement in a plastic bag or inside the glove port avoiding contact with the wound. Umbilical fascial incisions were meticulously closed with non-absorbable sutures. Results: Two patients with a history of previous abdominal surgery required omental adhesiolysis. Seventeen patients with breast cancer underwent bilateral salpingo-oophorectomy, ten had ovarian cystectomy (6 had cystadenoma, 2 had endometriotic cysts and 2 had dermoid cyst, six had excision of paraovarian cysts (one along with partial salpingectomy and four with ruptured ectopic pregnancy underwent salpingectomy. LESS was completed in all but one patient, who required insertion of an additional 5 mm port. There were no intra- or post-operative complications. Conclusions: Our experience confirms the feasibility and safety of LESS in a variety of benign adnexal pathology. Both the SIMP and HMGP approaches seem comparable. Performing LESS without the use of specialised access ports or instruments makes it cost effective and suitable for wider application.

    Female adnexal tumor of probable Wolffian origin (FATWO) is a rare neoplasm which is usually considered as benign, although in some cases metastasis or recurrences have been reported even after a long interval following the initial diagnosis. Preoperative diagnosis of FATWO is very difficult because of the rarity of the disease and the limited literature available. In this case report, we present a case of FATWO arising from the ovary and review the literature based on the clinical characteristics and management of this rare condition. A 51- year- old postmenopausal woman was referred to our clinic for evaluation of an adnexal mass. After diagnostic evaluation, the patient underwent explorative laparotomy. Intra-operatively, a solid- cystic mass was found in the right ovary, the rest of the abdomen and the pelvis were normal. The ovarian mass was removed and examined with frozen-section (FS). When the frozen section proved negative for malignancy, total abdominal hysterectomy and bilateral adnexectomy were performed. The anatomic study revealed a well-capsulated mass which was 3.5×1.5 cm in diameter. Based on pathological and immunohistochemical results, the final diagnosis was concluded to be FATWO. Adjuvant therapy was not administered. Te patient was followed up after discharge from the hospital. One year after surgery she was asymptomatic. No evidences of recurrence were observed throughout this period. Although FATWOs are rare tumors, they should be kept in mind in women with an abdominal mass. They can present diagnostic difficulties and the diagnosis is based on the exclusion of other neoplasms. FATWO has malignant potential, after the initial surgical treatment patients should be appropriately followed up for possible recurrence and metastasis.

    Adnexal carcinomas (ACs) are rare cutaneous malignancies of sweat gland or pilosebaceous origin. Optimal treatment and metastatic potential of AC are poorly defined. Mohs micrographic surgery (MMS) has been increasingly used to treat AC. To review selected primary cutaneous AC and their treatment outcomes with MMS. Literature review using PubMed search for articles related to primary cutaneous ACs. Sebaceous carcinoma treated with MMS recurred and metastasized in 6.4% and 3.7%, respectively. Primary cutaneous mucinous carcinoma treated with MMS recurred and metastasized in 9.6% and 6.4%, respectively. After MMS, 4.7% of microcystic AC recurred with no reported metastases. After MMS, recurrences and metastases of trichilemmal carcinoma or hidradenocarcinoma have not been reported. Two (4.2%) regional lymph node metastases but no distant metastases or local recurrences have been reported in eccrine porocarcinoma. Squamoid eccrine duct tumor, pilomatrix carcinoma, and spiradenocarcinoma treated with MMS are also reviewed. The rarity of ACs and the lack of comparative data on treatment makes conclusive recommendations on treatment difficult. Recent large case series and reviews suggest MMS is a useful and possibly superior treatment for AC and should be considered if primary cutaneous disease is suspected.

    Full Text Available AIM: To study the incidence, epidemiology, and clinical characteristics of incidental malignant periocular tumors at the royal medical services hospitals of Jordan.METHODS: Retrospective medical charts of 327 patients with malignant periocular tumor diagnosis at Jordan military hospitals between 2004 and 2015 were reviewed. Study variables included age, gender, city where patient lived, the presenting complaint(not caused by or related to tumor, clinical and histological diagnosis, size of the tumor, location, and surgical procedure.RESULTS:A total of 327 charts reviewed, 46(14.1%patients were found to have incidental malignant periocular tumor. Males where affected more than females with a ratio of 2:1. The average age was 66.39±10.59(22-83y. The most common presenting symptom or disease was blurring of vision secondary to cataract(44%, followed by combined cataract and other associated complaints such as epiphora in 21.7%.Preliminary clinical diagnosis corresponded with histological diagnosis in 95.7% of skin cancer. The average size of the lesions was 1.04×0.85 mm2(0.2×0.2-3.0×3.0 mm2. There was no significant relationship between the maximum diameter of the tumor and age of the patient,(P=0.105. The most frequent location of tumors was the lower eyelid(30.4%followed by the medial canthus(26.1%. The follow up period ranged between 6mo and 3y(average 9.3mo.CONCLUSION: Incidental malignant periocular malignant tumors were relatively common in this study, which urges excision of any suspicious lesion particularly young patients. A prospective study is needed to investigate the reasons why some patients neglect these lesions.

    2018-01-01

    Full Text Available The primary and metastatic tumors of the skin can be effectively diagnosed by fine needle aspiration cytology (FNAC; however, the cytomorphological features of skin adnexal tumors are rarely described in the literature. We hereby describe the cytological features of two histologically confirmed cases of benign skin adnexal tumors. Case 1 is of a 46-year-old female who presented with an elevated firm nodule over the scalp. A cytological diagnosis of benign adnexal tumor possibly of sebaceous origin was given. The nodule was excised and histopathological examination confirmed the diagnosis of sebaceoma. Case 2 is of a 19-year-old male who presented with a pigmented scalp swelling. Cytomorphological features were suggestive of benign skin adnexal tumor with foci of melanin pigment. The swelling was excised and histopathological examination confirmed the diagnosis of eccrine poroma. To the best of our knowledge, only one previous report of sebaceoma and no report of eccrine poroma describing the cytological findings of these two tumors exist. We report these two cases of benign skin adnexal tumors to discuss the cytological features and the potential diagnostic dilemma that they pose to the cytologist.

    To identify the causes of sports-related eye and adnexal injuries in children in Perth, Western Australia, to determine which sporting activities pose the highest risk of eye and adnexal injury to children. We performed a 12-year retrospective review of children admitted to hospital from 2002 to 2013 with sports-related ocular and adnexal eye injuries. The main outcome measures were the cause and type of ocular and adnexal injuries, age and gender risk factors. A total of 93 cases of sports-related ocular and adnexal injury were identified in the 12-year time period. A peak in injuries occurred for 12- to 14-year-olds with a second peak in 6- to 8-year-olds; the median age was 8.82 years (range = 1.59-16.47). Cycling, football (including soccer and Australian Rules Football), tennis, trampolining, fishing and swimming were the sports responsible for the greatest number of injuries, a total of 63%. More than one-third (35%) of injuries resulted from being struck by a blunt object, and more than a quarter (26%) were as a result of contact with a blunt projectile. Serious ocular and adnexal injuries have occurred in children as a result of participating in sports, with cycling and football being the largest contributors in the 12-year period we assessed. As we continue to encourage children to spend more time participating in sports and recreational activities, identifying associated risk factors will help us develop injury prevention strategies to promote eye safety for children. © 2015 Acta Ophthalmologica Scandinavica Foundation.

    2016-01-01

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

    Ocular adnexal lymphomas are a group of heterogeneous neoplasms representing approximately 1-2% of non-Hodgkin lymphomas and 8% of extranodal lymphomas. The incidence of primary ocular adnexal lymphoid tumors has raised over the last decades, and this could be probably attributed to the more sophisticated diagnostic techniques. Due to the wide spectrum of clinical manifestations, ocular tissue biopsy is important in order to set a precise diagnosis based on histological, immunophenotypical and, in some cases, molecular findings. The most common subtype, which may account for up to 80% of primary ocular adnexal lymphomas, is extranodal marginal zone lymphoma (EMZL) of mucosa-associated lymphoid tissue. This lymphoma is usually asymptomatic in the early phase of the disease causing a delay in the final diagnosis and prompt therapy. The pathogenesis of a proportion of these tumors has been linked to chronic inflammatory stimulation from specific infectious factors (e.g., Chlamydia psittaci) or to autoimmunity. The further improvement in diagnostic methods and the further understanding of the pathogenesis of ocular adnexal EMZL may contribute to the establishment of a more successful multidisciplinary therapeutic planning.

    Current staging systems do not specifically address cutaneous adnexal carcinomas with eccrine differentiation. Due to their rarity, prognosis and management strategies are not well established. A population-based study was performed to determine prognostic factors and survival. Patients diagnosed with cutaneous adnexal carcinomas with eccrine differentiation were identified using the surveillance, epidemiology, and end results population-based cancer registry. Associations between risk factors, treatment modalities, and survival were calculated using logistical regression, Kaplan-Meier estimates and log-rank analysis. The incidence of distinct eccrine subtypes was determined within 1,045 patients with cutaneous adnexal tumors containing eccrine differentiation. All-cause 5-year survival (OS) was 82%, while age-adjusted survival was 94%. Patients with microcystic adnexal carcinoma had improved OS (90%) compared to patients with hidradenocarcinoma (74%), spiradenocarcinoma (77%), porocarcinoma (79%), and eccrine adenocarcinoma (81%). The majority of patients were treated with surgical excision and a small subset with surgery plus radiation, with similar OS. Patients with well-to-moderately differentiated tumors demonstrated improved OS compared to those with poorly differentiated/anaplastic disease. Histological subtype and grade were associated with survival, and should be specified in biopsies and excised specimens. Surgical excision is appropriate, and the addition of adjuvant radiation may not be associated with survival. These results highlight survival data and high-risk prognostic factors that warrant prospective validation, and may augment current staging systems. Copyright © 2013 Wiley Periodicals, Inc.

  19. The Role of Infectious Agents in the Etiology of Ocular Adnexal Neoplasia

    2008-01-01

    Given the fact that infectious agents contribute to around 18% of human cancers worldwide, it would seem prudent to explore their role in neoplasms of the ocular adnexa: primary malignancies of the conjunctiva, lacrimal glands, eyelids, and orbit. By elucidating the mechanisms by which infectious agents contribute to oncogenesis, the management, treatment, and prevention of these neoplasms may one day parallel what is already in place for cancers such as cervical cancer, hepatocellular carcinoma, gastric mucosa-associated lymphoid tissue lymphoma and gastric adenocarcinoma. Antibiotic treatment and vaccines against infectious agents may herald a future with a curtailed role for traditional therapies of surgery, radiation, and chemotherapy. Unlike other malignancies for which large epidemiological studies are available, analyzing ocular adnexal neoplasms is challenging as they are relatively rare. Additionally, putative infectious agents seemingly display an immense geographic variation that has led to much debate regarding the relative importance of one organism versus another. This review discusses the pathogenetic role of several microorganisms in different ocular adnexal malignancies, including human papilloma virus in conjunctival papilloma and squamous cell carcinoma, human immunodeficiency virus in conjunctival squamous carcinoma, Kaposi sarcoma-associated herpes virus or human herpes simplex virus-8 (KSHV/HHV-8) in conjunctival Kaposi sarcoma, Helicobacter pylori (H. pylori,), Chlamydia, and hepatitis C virus in ocular adnexal mucosa-associated lymphoid tissue lymphomas. Unlike cervical cancer where a single infectious agent, human papilloma virus, is found in greater than 99% of lesions, multiple organisms may play a role in the etiology of certain ocular adnexal neoplasms by acting through similar mechanisms of oncogenesis, including chronic antigenic stimulation and the action of infectious oncogenes. However, similar to other human malignancies

    To evaluate the nature and imaging appearance of incidental enhancing breast lesions detected on a routine contrast-enhanced chest CT. Twenty-three patients with incidental enhancing breast lesions on contrast-enhanced chest CT were retrospectively reviewed. The breast lesions were reviewed by unenhanced and enhanced CT, and evaluated by observing the shapes, margins, enhancement patterns and backgrounds of breast lesions. A histopathologic diagnosis or long-term follow-up served as reference standard. Sixteen (70%) patients had malignant breast lesions and seven (30%) had benign lesions. In 10 patients, the breast lesions were exclusively detected on contrast-enhanced CT. Using unenhanced CT, breast lesions with fi broglandular backgrounds were prone to be obscured (p < 0.001). Incidental primary breast cancer showed an non-significant trend of a higher percentage irregular margin (p = 0.056). All of the four incidental breast lesions with non-mass-like enhancement were proven to be malignant. Routine contrast-enhanced chest CT can reveal sufficient details to allow for the detection of unsuspected breast lesions, in which some cases may be proven as malignant. An irregular margin of incidental enhancing breast lesion can be considered a suggestive sign of malignancy

    The aim of this study was to assess the efficacy of an educational framework encouraging the systematic application of national societal recommendations regarding the imaging evaluation and follow-up of incidental findings (IFs) in the emergency department. After institutional review board approval was received, consecutive CT and ultrasonographic examinations from the emergency department over a 2-month period were collected. Examination reports were categorized by study type and evaluated individually for the presence of IFs that fit into the following core categories: solid or subsolid pulmonary nodules, liver lesions, splenic lesions, gallbladder polyps, pancreatic cystic lesions, adrenal nodules, adnexal cysts on CT or ultrasonography, thyroid nodules (CT), and abnormal lymph nodes. Subsequently, after an educational intervention consisting of printed and electronic references, e-mail, and verbal communication detailing societal guidelines and the introduction of voice recognition macros, data were recollected in the same fashion for an additional 2-month period. A total of 3,131 imaging events occurred in the 2-month preintervention period, yielding 514 total incidental findings. Of these 514 findings, 67.5% were correctly managed and 32.5% were incorrectly managed according to societal recommendations. In the postintervention period, 3,793 imaging events yielded 499 total incidental findings. Of these 499 findings, 80.2% were correctly managed and 19.8% were incorrectly managed. The increased rate of reporting incidental findings in concordance with societal guidelines was statistically significant (P societal guidelines for incidental findings. Compliance with societal guidelines improves patient care and has cost-saving implications. Copyright © 2016 American College of Radiology. Published by Elsevier Inc. All rights reserved.

  4. Ultrasonography of adnexal causes of acute pelvic pain in pre-menopausal non-pregnant women

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

    2016-04-01

    Full Text Available Despite of the fact that the vulva contains a high density of apocrine and anogenital mammary glands in addition to eccrine glands and folliculosebaceous units, the benign vulvar adnexal tumours are rare. Though the varied clinical presentation and diverse histopathological spectrum of vulvar neoplasms has amazed the pathologists, only few studies have been reported in literature. The present five year study consists of only five cases of benign vulvar neoplasms depicting their rarity. Hidradenoma papilliferum and syringoma were the most common entities followed by Chondroid syringoma. The aim of our study is to explore and highlight the histopathological diversity of benign vulvar adnexal tumours reflecting the relative frequency of these structures.

    Metastasizing adnexal carcinomas are rare; thus, currently there is no uniform treatment guideline. Chemotherapeutic drugs that selectively target cancer-promoting pathways may complement conventional therapeutic approaches. We performed immunohistochemistry (epidermal growth factor receptor (EGFR), HER2, and CD117), EGFR and ERBB2 fluorescence in situ hybridization (FISH), and multiplexed SNaPshot® genotyping (testing for recurrent mutations in 15 cancer genes including BRAF, EGFR, KRAS, PIK3CA, and TP53) on primary tumors and corresponding metastases of 14 metastasizing adnexal carcinomas (three apocrine, six eccrine, two hidradenocarcinomas, two porocarcinomas, and one aggressive digital papillary adenocarcinoma). Metastasis to regional lymph node was most common, followed by skin and then lungs. Follow-up was available in 12 patients (5 months to 8 years) with 1 died of widespread metastases. Although EGFR overexpression was a prevalent feature in this cohort, seen in 7/11 (64%) primary tumors and 10/14 (71%) metastases; FISH for EGFR gene amplification was negative in 9 tested primary tumors and 12 metastases. FISH of the one primary tumor and three metastases with 2+ HER2 overexpression revealed a low level of ERBB2 gene amplification in one apocrine carcinoma and corresponding metastasis. CD117 expression was seen only in rare cases. PIK3CA (2/12, 17%) and TP53 (3/12, 25%) mutations were detected in two (one hidradenocarcinoma, one porocarcinoma) and three (one eccrine, one hidradenocarcinoma, and one aggressive digital papillary adenocarcinoma) cases, respectively. The role of EGFR inhibitor therapy in metastasizing adnexal carcinomas with protein overexpression remains unclear. Targeted therapy including PI3K pathway inhibitors might be a potential treatment for rare cases of adnexal carcinomas with metastases.

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

  8. Clinical Aspects of IgG4-Related Orbital Inflammation in a Case Series of Ocular Adnexal Lymphoproliferative Disorders

    2012-01-01

    Full Text Available The most frequent ocular adnexal tumors and simulating lesions are lymphoproliferative disorders (LPDs, including malignant lymphomas and orbital inflammation with lymphoid hyperplasia or infiltration. IgG4-related orbital inflammation (IgG4-ROI often involves lacrimal glands and other orbital tissues and is an important differential diagnosis. The present study evaluated clinical aspects of IgG4-ROI in a case series of orbital LPD. Sixty-two consecutive cases of orbital LPD, pathologically diagnosed from November, 2004, through March, 2011, were investigated. Histological types were 22 cases with MALT lymphoma, 11 cases with diffuse large B-cell lymphoma (DLBCL, 3 cases with other malignant lymphomas, 16 cases with IgG4-ROI, and 10 cases with non-IgG4-ROI. Ages of the IgG4-ROI group (56±10?yrs were significantly lower than the MALT lymphoma (71±12?yrs and DLBCL (75±14?yrs groups. Orbital lesions other than lacrimal glands were present in six cases including extraocular muscle swelling, mass lesions surrounding the optic nerve, and supraorbital and infraorbital nerves enlargements. Although none of the malignant lymphomas were related to IgG4, previous evidence suggested that malignant lymphomas can arise from IgG4-ROI. Based on this study (26% and another report (33%, it is likely that nearly a quarter of orbital LPD are IgG4-ROI.

    We retrospectively reviewed the results of radiotherapy for localized ocular adnexal MALT lymphoma (OAML) to investigate the risk factors of cataract. Sixty-seven patients with stage IE OAML treated with radiotherapy at Seoul St. Mary’s Hospital from 2001 to 2016 were included. Median treatment dose was 30 Gy. Lens protection was done in 52 (76%) patients. Radiation therapy (RT) extent was as follows: superficial (82.1%), tumor mass (4.5%), and entire orbital socket (13.4%). The risk factors for symptomatic cataract were analyzed using the Cox proportional hazard model. Median follow-up time was 50.9 months (range, 1.9 to 149.4 months). All patients were alive at the time of analysis. There were 7 recurrences and there was no local recurrence. Median time to recurrence was 40.4 months. There were 14 cases of symptomatic cataract. Dose >30 Gy had hazard ratio of 3.47 for cataract (p = 0.026). Omitting lens protection showed hazard ratio of 4.10 (p = 0.008). RT achieves excellent local control of ocular MALT lymphoma. Consideration of RT-related factors such as lens protection and radiation dose at the stage of RT planning may reduce the risk of RT-induced cataract after radiotherapy.

  10. Autoamputation of the Appendix in a Chronic Adnexal Abscess

    2018-01-01

    Full Text Available Autoamputation of the appendix has rarely been described in the literature. We present a case of a pelvic mass, thought to be a dermoid cyst based on preoperative imaging. After surgical removal and pathological examination, the mass was found to be a chronic pelvic abscess containing the right adnexa as well as an autoamputated vermiform appendix. Differentiating between gynecologic and gastrointestinal disease preoperatively can be difficult and often a definitive diagnosis cannot be made until surgical exploration and pathological review. However, to our knowledge, this is the first described case of a chronic pelvic abscess containing an autoamputated vermiform appendix.

  11. INCIDENTAL VOCABULARY LEARNING THROUGH READING

    Directory of Open Access Journals (Sweden)

    Holly Warzecha, M.A. TESOL

    2017-04-01

    Full Text Available The purpose of the following paper is to take a closer look at the benefits of incidental learning through reading, with a specific focus on vocabulary acquisition. The teaching of vocabulary has traditionally been an explicit process where the target vocabulary is taken out of context and taught separately. However, this kind of explicit teaching and learning may only take into account a form-meaning connection. Therefore, this paper explores research on incidental learning and specifically looks at what it takes to acquire new vocabulary incidentally through reading while considering the coverage rates of texts, how many words must be known already from the text, how many repetitions it takes to learn a word, types of texts that promote learning, and the effects of pairing students‘ reading with learner tasks. After reviewing many studies, it can be concluded that more reading is better. More specifically, extensive reading of chosen novels at an appropriate level and interest to the students showed important gains in vocabulary. In addition, readings that were supplemented with additional activities that focused on both form and meaning showed an even higher increase in word retention.

    This study aims to evaluate the incidental findings on brain MRI of patients with cognitive function impairments. We analyzed magnetic resonance (MR) findings of 236 patients with decreased cognitive function. MR protocols include conventional T2 weighted axial images, fluid attenuated inversion recovery axial images, T1 weighted coronal 3-dimensional magnetization-prepared rapid acquisition of gradient echo and diffusion tensor images. We retrospectively evaluated the signal changes that suggest acute/subacute infarction and space occupying lesions which show mass effect. Incidental MR findings were seen in 16 patients. Nine patients (3.8%) showed increased signal intensity on trace map of diffusion tensor images suggesting acute/subacute infarctions. Space occupying lesions were detected in 7 patients, and 3 lesions (1.27%) had mass effect and edema and were considered clinically significant lesions that diminish cognitive functions. Several incidental MR findings were detected in patients with decreased cognitive function, and the incidence of aucte/subacute infarctions were higher. Proper evaluations of MRI in patients with impaired cognitive functions will be helpful in early detection and management of ischemic lesions and space occupying lesions.

    Thirty tumors including 27 distinctive cutaneous neoplasms and 3 metastatic tumors from 26 dogs were collected from diagnostic submissions to 3 laboratories. Characteristic histopathologic features included location in the subcutis or dermis (or both); lobular, nodular, and nest-like architecture; and a component of epithelioid cells with clear cytoplasm. Additional features present in most cases included follicular dermal papilla-like structures, low mitotic index, nuclear pleomorphism, necrosis, and mineralization. Cytoplasmic periodic acid Schiff-positivity, which was abolished by pretreatment with diastase, indicated the presence of glycogen in all cases. The oil red O stain did not demonstrate cytoplasmic lipid. Melanin granules, accentuated by the Fontana-Masson method, were observed infrequently. A sparsely cellular mucinous stroma and stromal cartilaginous differentiation were uncommon. By immunohistochemistry, neoplastic cells stained positively for cytokeratin (29 of 29), vimentin (28 of 28), S-100 protein (24 of 29), and melan A (8 of 12); results were negative for smooth muscle actin and calponin in all cases. Clinical follow-up information was obtained on all 26 dogs. One tumor recurred, 1 metastasized to a regional lymph node, and 1 metastasized to regional lymph nodes twice. In another case, possible pulmonary metastasis was noted radiographically. The findings are consistent with a poorly differentiated, low-grade, adnexal carcinoma of the skin. Similar canine cutaneous neoplasms have been reported as "clear-cell hidradenocarcinoma" and "follicular stem cell carcinoma." The authors propose the designation "cutaneous clear cell adnexal carcinoma."

    Porokeratotic adnexal ostial nevus (PAON) is a term that encompass porokeratotic eccrine ostial and dermal duct naevus and porokeratotic eccrine and hair follicle naevus. PAON is a rare adnexal hamartoma characterized by the presence of a cornoid lamella exclusively overlying eccrine acrosyringia or over both, eccrine acrosyringia and hair follicles. Most of the articles on PAON report its clinical or histopathological characteristics but literature review offer scarce data on the evolution or treatment. We have reviewed it. We report an 8-year-old boy with presence of bilateral asymtomatic verrucous lesions mostly in left side of the body without other added abnormalities through the twelve-year follow-up. As our case presented cornoid lamella overlying eccrine acrosyringia and hair follicles we diagnosed PEHFN. He received treatment with CO2 ablation in 2004 and in 2012 with marked improvement. Review of the previous reported cases of PAON show that it is mostly unilateral and that some patients have coexisting problems like seizures, left hemiparesis, scoliosis, deafness, developmental delay, palmoplantar keratoderma, psoriasis, hyperthyroidism, polinerupathy, breast hipoplasia and KID. PAON responded with tazaroten gel, dithranol short-contact treatment and topical photodynamic therapy but laser treatments appear to be more efficient in most patients. © 2014 European Academy of Dermatology and Venereology.

    A case of a middle aged woman with weight loss, lower abdominal pain and ascites, is presented who was initially suspected to have ovarian cancer. Her CA 125 was increased] ascetic fluid showed lymphocytic exudates but cytology failed to show any malignant cells. Operative biopsy showed numerous noncaseating granulomas in the omentum, uterus and ovaries. With treatment both the ascites and pleural effusion resolved and the CA 125 normalized. We emphasize the misleading raised CA 125 levels and radiologic pictures along with the importance of frozen-section analysis for definitive diagnosis to avoid unnecessary surgery. (author)

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

    To evaluate the prognostic utility of the American Joint Committee on Cancer (AJCC) staging system for ocular adnexal lymphoma (OAL).
 A multicenter, consecutive case series of patients with biopsy-proven conjunctival, orbit, eyelid, or lacrimal gland/sac lymphoma was performed. The electronic pathology and clinical records were reviewed for new or recurrent cases of ocular adnexal lymphoma. The main outcome measures included pathology and clinical staging (AJCC and Ann Arbor systems), treatment, and recurrence (local and systemic). Statistical analysis included demographic evaluations and the Kaplan-Meier survival probability method.
 Extranodal marginal zone B-cell lymphoma of mucosa-associated lymphoid tissue were the most common (n=60/83, 72%). The most common Ann Arbor clinical stages were IE (76%) followed by IIE (17%) and IIIE (7%). Pathology identified 13 cases (15%) that were upstaged to group IV (p=0.017). Similarly, AJCC clinical stages were cT1NOMO (21.7%), cT2NOMO (44.6%), cT3N0M0 (5%), and cT4NOMO (2.4%). Local control was achieved in 75% of treated patients. There were 19 local recurrences from which 14 (74%) belonged to the non-radiation treatment groups. Lower-risk groups (T1 and T2 without lymph node involvement or metastatic disease of AJCC and IE of Ann Arbor) had longer disease-free survival than the higher-risk groups (AJCC T1, T2 with nodal involvement or metastatic disease, T3, and T4 as well as Ann Arbor II, III, and IV). The overall mean follow-up was 43.3 months (range 6-274).
 Regardless of stage, recurrence and disease-free survival were more closely related to treatment and histopathology rather than tumor size or site-specific location.

    The aim of this study was to establish normal ophthalmic parameters for selected diagnostic tests, and to describe the orbital anatomy and adnexal histology of the broad-snouted caiman. A total of 35 Caiman latirostris that were free of obvious ocular diseases were used to measure the parameters in this investigation. Ages ranged from 5 to 15 years. Ophthalmic diagnostic tests were conducted, including evaluation of tear production with Schirmer Tear test-1 (STT1), culture of the conjunctival bacterial flora, applanation tonometry, conjunctival cytology, nictiating membrane incursion frequency test (NMIFT), endodontic absorbent paper point tear test (EAPPTT), palpebral fissure length measurement (PFL) and B-mode ultrasonography. Adnexal histology and skull samples were studied. Mean (±SD) STT1 was 3.4 ± 3.6 mm/min (95% confidence interval of 2.01-4.78 mm/min), intraocular pressure (IOP) was 12.9 ± 6.2 mmHg, NMIFT was 6.0 ± 3.5, EAPPTT was 17.1 ± 2.5 mm/min, PFL was 28.9 ± 3.0 mm, anterior chamber depth was 3.1 ± 0.3 mm, lens axial length was 8.4 ± 0.6 mm, vitreous chamber depth was 7.9 ± 0.7 mm and axial globe length was 19.9 ± 1.3 mm. For all animals evaluated, Bacillus sp., Diphteroids and Staphylococcus sp. were predominant. © 2013 American College of Veterinary Ophthalmologists.

    The principal aim of this study was the predictability of malignant ovarian tumors and to determine a cut-off value for this score to indicate the risk of malignancy that would be easy to use in clinical practice. We retrospectively calculated the ADNEX score for all patients who underwent surgery for ovarian tumours in two Burgundy hospitals (Dijon University Hospital and Chalon-sur-Saône Hospital). We used the nine criteria of the ADNEX model. The inclusion criteria were the presence of all of the ADNEX criteria and a histology result. We analysed the sensitivity, specificity, PPV and PNV of four cut-offs (3%, 5%, 10% and 15%) for the entire pool then by age groups; from 14 to 42 (group 1) and 43 and more (group 2) RESULTS: Two hundred and eighty-four patients managed for an ovarian tumour were included between the 1st January 2013 and the 31st December 2015. Our AUC was of 0.94 (95% CI [0.903-0.977]) for discrimination between benign and malignant ovarian tumors. For a cut-off of 10%, sensitivity was 90%, specificity was 81.1%, PPV was 34.6% and PNV 98.5%. Results were lower for young women than for the second group. For a cut-off of 10%, group 1 had a sensitivity of 77.7% and specificity of 89.6%, PPV of 46.6% and PNV 97.5%. For the group 2, sensitivity was 95.2%, specificity was 76.6%, PPV was 33.8% and PNV was 99.2%. The most reasonable cut-off for the whole pool was 10%. For group 1 a cut-off of 5% was retained due to the less satisfying detection of "borderline" tumours more frequent in younger patients. For group 2 the cut-off of 10% gave the best results. In our study, a lower cut-off for younger women seemed better suited to discriminate borderline tumours. In practice, the ADNEX score associated with the peroperative laparoscopic examination seems to be the best way to use the ADNEX model. Our study showed that the ADNEX model allows a good predictability of malignant ovarian tumours. The predictability becomes less satisfying for the youngest patients

    Fetal magnetic resonance imaging (MRI) is a routinely used tool in prenatal diagnosis; however, there is a lack of studies evaluating incidental findings observed in the mother. This study describes and quantifies incidental findings observed in the mother during fetal MRI. We reviewed all fetal MRI studies at the University of Minnesota Medical Center from February 2008 to September 2014. Two pediatric radiologists retrospectively conducted a consensus evaluation. The maternal findings were categorized into neurologic, gynecologic, urinary, gastrointestinal and musculoskeletal. Hydronephrosis consistent with the stage of pregnancy was recorded but was not included as an abnormal finding. Abnormal findings were classified into three groups, depending on their clinical significance: level I (low), level II (medium) and level III (high). We evaluated 332 pregnant patients with a mean age of 29.3 years and a mean gestational age of 29 weeks. Of these, 55.4% had at least 1 incidental finding, for a total of 262 incidental maternal findings. Of the 262 abnormalities, 113 (43.1%) were neurologic, 69 were gynecologic (26.3%), 36 (13.7%) urinary, 24 (9.2%) gastrointestinal and 20 (7.6%) musculoskeletal. Of the 262 incidental findings, 237 (90.5%) were level I, 24 (9.2%) were level II and 1 (0.4%) was level III. Our results suggest that although the vast majority of incidental maternal findings are benign, more significant findings are still encountered and should be expected. (orig.)

    Full Text Available Gallbladder cancer (GBC represents 3.8% of all gastrointestinal cancers and usually known to be of a poor prognosis. In 0.2–2.9% of cases, this cancer is found in cholecystectomy specimens. A better understanding of spread mode of this tumor helps a better surgical management. The aim of the present review is to underline the management of GBC based on the comprehension of risk factors and anatomic features. A Medline, PubMed database search was performed to identify articles published from 2000 to 2011 using the keywords ‘carcinoma of gallbladder’, ‘incidental gallbladder cancer’, ‘gallbladder neoplasm’ and ‘cholecystectomy’. Some pathological situations such as chronic lithiasis and biliopancreatic junction abnormalities have been clearly identified as predisposing to GBC. Laparoscopy increases peritoneal and parietal tumor dissemination, thus, it should not be performed when GBC is suspected. Most determinant prognostic factors are nodal, perineural and venous involvement, invasion of the cystic duct and the tumor differentiation. The simple cholecystectomy is sufficient for tumors classified as T1a; for other cancers exceeding the muscularis, radical re-resection is required due to the high risk of recurrence. This aggressive surgery improved the overall survival of patients. There is still no standard adjuvant treatment; patients should be included in prospective trials.

    Ovarian dysgerminoma cases very rarely present with acute abdomen due to adnexal torsion and the successful laparoscopic management of such a case has not been reported previously. A 17-year-old sexually inactive high school girl presenting with acute abdomen was referred to our emergency department. Transabdominal ultrasonography showed the presence of homogeneous tumor in the lower abdomen. Emergency laparoscopic surgery was performed and left ovarian tumor with adnexal torsion was identified. Left salpingo-oophorectomy was performed carefully to avoid damaging the tumor capsule and the excised tissue was removed after retrieval in an endobag. The histopathological diagnosis was pure ovarian dysgerminoma. The postoperative course was uneventful. Laparoscopic management with careful postoperative follow-up to monitor recurrence could be a treatment option in a young girl with dysgerminoma, if the disease condition is detected in the early stage.

    Retrospective database analysis. To determine the impact of obesity on the rate of incidental durotomy in lumbar spine surgery. There is a paucity of data on the overall impact of obesity on the rate of incidental durotomy in lumbar spine surgery, specifically with regard to the type of procedure performed. A large administrative database was queried for all patients who underwent lumbar spine surgery for decompression and/or fusion. They were then stratified into separate cohorts on the basis of body mass index and by procedural codes. Documentation of incidental durotomy was noted. Patient demographics and associated comorbidities were assessed. Odds ratios and 95% confidence intervals were calculated and χ test was used to assess for statistical significance. The incidental durotomy ranged from 0.5% to 2.6%, with the highest rates observed in multilevel laminectomies and revision decompressions in the obese and morbidly obese groups. For patients who underwent decompression only procedures, nonobese patients had a significantly lower rate of durotomy than the obese and morbidly obese cohorts. For patients who underwent fusion with or without decompression, there was a significantly increased rate of durotomy in obese patients compared with nonobese patients. The morbidly obese cohort also had significantly higher rates of incidental durotomy than the nonobese cohort in both revision decompression and revision fusion procedures. This analysis of a large administrative database demonstrates that obesity is associated with increased rates of incidental durotomy in lumbar spine surgery. Furthermore, obesity, in association with increasing complexity of the procedure, increases the rate of incidental durotomy in lumbar spine surgery. Surgeons must be aware of these increased risks as the rate of obesity increases in the population. 3.

    Adnexal carcinomas are rare and diverse cutaneous tumours. They are locally aggressive and have the potential for distant metastasis. Metastatic adnexal carcinomas are very resistant to conventional chemotherapies. Sunitinib, an oral tyrosine kinase inhibitor, is reportedly effective for the treatment of various solid cancers. Its use in adnexal carcinomas has never been reported. The first patient had metastatic clear cell hidradenocarcinoma and was stabilized over 8 months with sunitinib, before she relapsed. The second patient had a metastatic malignant hair follicle tumour (trichoblastic carcinoma) and achieved a partial remission with sunitinib, and disease stabilized after 10 months. Dynamic contrast-enhanced ultrasound (DCE-US) performed to evaluate tumour vascularization during treatment depicted a dramatic and early decrease in the tumour blood volume. Sunitinib was effective in controlling the disease in our two patients. DCE-US using linear raw data may have an early predictive value for tumour response to sunitinib. Further studies involving larger cohorts of patients are warranted in order to confirm the efficacy of sunitinib in these rare tumours.

    The aim of our work was to study the specificity of MRI in comparison with transvaginal US for differentiation of malignant from benign adnexal lesions. A total of 67 patients with clinically suspicious adnexal lesions were evaluated by MRI. Transaxial and coronal images were acquired using T1-weighted sequences before and following IV contrast and T2-weighted sequences. In all patients transvaginal ultrasound examinations (TVUS) were performed. For both imaging modalities each lesion was classified separately as either benign or malignant according to previously published criteria. Pathologic findings were available in 65 cases. Both MRI and TVUS correctly classified the 12 malignant lesions (sensitivity 100 %). Specificity (MRI: 78.2 %, TVUS: 65.5 %) and accuracy (MRI: 82 %, TVUS: 71.6 %) were higher with MRI than with TVUS, but differences were statistically not significant (p = 0.18 and p = 0.20, chi-square test). There was agreement/disagreement between findings of MRI and US in 52/15 lesions. The macroscopic criteria for malignancy are unspecific and result in a limitation of the specificity of both MRI and TVUS. The MRI technique is a valuable adjunct to TVUS by enabling further clarification of adnexal tumors with equivocal complex or solid vaginal sonographic findings. (orig.)

    Carry out a preliminary study comparing postoperative pain and intraoperative and postoperative complications between micro-laparoscopy and laparoscopic monotrocart non-oncological adnexal surgery. All patients should benefit from a benign adnexal surgery were included prospectively from February to May 2014. The insufflation pressure, infiltration of trocar holes with a local anesthetic, postoperative analgesics were prescribed standardized. Operative and postoperative complications, type and length of hospital stay as well as EVA and analgesic consumption were recorded. Nine patients were included in monotrocart group versus 7 in the micro-laparoscopy group. There were no differences in operative and postoperative complications, the type and length of hospital stay, as well as cosmetics satisfaction. However, there was a significant difference in the VAS to D2 (2.15 vs. 4.08, P=0.04) and analgesic consumption at D0 (P=0.04), D1 (P=0.04), D2 (P=0.02) and D3 (P=0.01), for the benefit of micro-laparoscopy. Despite an enrollment of patients low, micro-laparoscopy appears to have a significant advantage over the monotrocart laparoscopy for postoperative pain in benign adnexal surgery.

    The increasing use of magnetic resonance imaging (MRI) in clinical diagnostics means that patients and physicians are confronted more often with incidental findings. In the literature there are fluctuating data on the incidence of such findings and guidelines concerning the further procedure exist in only very few cases, such as incidental aneurysms and pituitary adenomas. The diagnostic and therapeutic implications which can be derived from incidental findings depend on multiple factors, such as anatomical location, patient age, comorbidity and patient wishes. For this reason it often makes sense to refer patients with incidental findings to an interdisciplinary neurological center at an early stage. In this review frequent incidental cerebral findings, epidemiological data, imaging criteria and, where possible, recommendations for the further procedure are shown. (orig.) [German] Durch den gehaeuften Einsatz der MRT in der zerebralen Diagnostik werden Arzt und Patienten in zunehmendem Masse mit Zufallsbefunden, auch Nebenbefunde genannt, konfrontiert.

B. das inzidentelle Aneurysma oder das Hypophysenadenom, existieren Leitlinien fuer das weitere Prozedere. Die aus einem Zufallsbefund abzuleitenden diagnostischen und therapeutischen Konsequenzen sind von vielen Faktoren, wie z.

Daher ist es oft sinnvoll, den Patienten mit einem Zufallsbefund fruehzeitig in einem interdisziplinaeren Neurozentrum vorzustellen.

  12. Mass

    International Nuclear Information System (INIS)

    Quigg, Chris

    2007-01-01

    In the classical physics we inherited from Isaac Newton, mass does not arise, it simply is. The mass of a classical object is the sum of the masses of its parts. Albert Einstein showed that the mass of a body is a measure of its energy content, inviting us to consider the origins of mass. The protons we accelerate at Fermilab are prime examples of Einsteinian matter: nearly all of their mass arises from stored energy. Missing mass led to the discovery of the noble gases, and a new form of missing mass leads us to the notion of dark matter. Starting with a brief guided tour of the meanings of mass, the colloquium will explore the multiple origins of mass. We will see how far we have come toward understanding mass, and survey the issues that guide our research today.

    Malignant cutaneous adnexal tumors (MCATs) are rare neoplasms that do not have a well-studied treatment algorithm. They are generally treated by excision alone. Given its successful application in other cutaneous malignancies, sentinel lymph node biopsy (SLNB) has been advocated by some for use in MCATs. A retrospective chart review was performed. Clinicopathological factors, recurrence patterns, and long-term follow-up were documented. Survival analysis was performed. Forty-eight subjects were identified. Mean age was 69 years with locations on the face (52%), including periocular sites (16%), extremities (25%), and all other sites (7%). Histologic distribution was sebaceous carcinoma (56%), porocarcinoma (17%), eccrine carcinoma (13%), adenocarcinoma (10%), and hidradenocarcinoma (4%). Mean follow-up was 3.9 years (range, 0 to 17 years). Nine subjects (18.8%) recurred locally, and recurrence was inversely associated with age (P = 0.04). Four (8.3%) demonstrated lymph node involvement, none without first developing local recurrence. Five-year disease-specific survival was 97 per cent (confidence interval, 81.4 to 99.6%). Despite being one of the largest reported analyses of MCATs, this study is limited by the small number of subjects. MCATs seemingly develop nodal recurrence only after demonstrating aggressive local biology. SLNB may best be applied selectively, possibly only in patients with local recurrence.

    Besides the upper abdominal parenchymal organs, the increasing application of cross-sectional imaging has also led to a rising number of incidental findings in the kidneys, adrenal glands, adnexa uteri, the gastrointestinal tract, mesentery and abdominal lymph nodes. Abdominal computed tomography investigations often show unexpected findings without any correlating symptoms. The growing clinical relevance is due to the large number of incidental findings as well as an increasing awareness of ethical and socioeconomic factors. When interpreting radiological findings not only morphological criteria but also individual risk factors of the patient and the clinical context are of great importance. The aims of this article are the description and evaluation of frequent incidental findings detected by computed tomography and to provide information about management recommendations. (orig.) [German] Neben den parenchymatoesen Oberbauchorganen hat der zunehmende Einsatz von Schnittbildverfahren zu einer vermehrten Anzahl von Zufallsbefunden der Nieren, Nebennieren, Adnexe, des Gastrointestinaltrakts, Mesenteriums und der intraabdominellen Lymphknoten gefuehrt. Abdominelle CT-Untersuchungen zeigen haeufig unerwartete Befunde ohne korrelierende Symptomatik. Die steigende klinische Relevanz ist einerseits auf die Zunahme inzidenteller Pathologien und andererseits auf ein wachsendes Bewusstsein ethischer und soziooekonomischer Faktoren zurueckzufuehren.

    In many everyday decisions, people exhibit loss aversion-a greater sensitivity to losses relative to gains of equal size. Loss aversion is thought to be (at least partly) mediated by emotional--in particular, fear-related--processes. Decision research has shown that even incidental emotions, which are unrelated to the decision at hand, can influence decision making. The effect of incidental fear on loss aversion, however, is thus far unclear. In two studies, we experimentally investigated how incidental fear cues, presented during (Study 1) or before (Study 2) choices to accept or reject mixed gambles over real monetary stakes, influence monetary loss aversion. We find that the presentation of fearful faces, relative to the presentation of neutral faces, increased risk aversion-an effect that could be attributed to increased loss aversion. The size of this effect was moderated by psychopathic personality: Fearless dominance, in particular its interpersonal facet, but not self-centered impulsivity, attenuated the effect of incidental fear cues on loss aversion, consistent with reduced fear reactivity. Together, these results highlight the sensitivity of loss aversion to the affective context. (c) 2016 APA, all rights reserved).

    Full Text Available Thymoma, the most common neoplasm of the anterior mediastinum, is a rare tumor of thymic epithelium that can be locally invasive. We reported 2 cases of invasive thymoma incidentally found during routine coronary artery bypass graft (CABG surgery at Faghihee Hospital of Shiraz University of Medical Sciences of Iran in a period of about 6 months. The 2 patients were male and above 60 years old. They had no clinical symptoms and radiological evidence of mediastinal mass before detection of the tumor during operation. For both patients mass was completely excised and sent to the laboratory. The ultimate pathological diagnosis of both masses was invasive thymoma (stage 2. There are few reports in which thymomas were found incidentally during cardiac surgery. In spite of rare coincidence, due to being asymptomatic and possibly invasive, special attention to thymus gland during cardiac surgery or other mediastinal surgery and preoperative imaging studies seem to be reasonable approach.

    To analyze the incidence and severity of ocular and adnexal injuries in the Second Lebanon War among Israeli soldiers and civilians. Retrospective cohort study. All patients recorded in the Israeli National Trauma Registry during the Second Lebanon War (July-August, 2006). Retrieval of all data relevant to ocular and adnexal injuries sustained during the study period, and differentiation between those associated with combat/terrorist and other events. Analysis of data according to the severity of trauma , anatomical location of the injury, and whether the patients were military personnel or civilians. A total of 69 war-related ocular trauma patients (58 military personnel and 11 civilians) were registered during the 34 days of war. The injuries involved the anterior segment injury (n = 25), posterior segment (n = 29) and the periocular region (n = 15, all severe). Twenty-seven of the patients had open-globe injuries, of which 18 involved intraocular foreign bodies, and 27 patients had closed-globe injuries. The rate of ocular injuries was 7% among all registered wounded military personnel and 1.2% among all injured civilians. The incidence and severity of ocular and adnexal injuries among military personnel during the Second Lebanon War were consistent with previous reports from American sources of ocular injuries sustained in Iraq and Afghanistan. The rates of ocular injury associated with wartime events sustained by civilians has not been investigated before, and it was relatively low, probably as a result of stringent government-mandated building regulations for passive defense that are discussed.

  20. Incidental Vocabulary Learning in Second Language Acquisition: A Literature Review

    Falcon Dario Restrepo Ramos

    2015-01-01

    Full Text Available This literature review aims to analyze previous studies that address the incidental learning of vocabulary in second language acquisition. The articles included in this literature review look into the understanding of vocabulary learning through incidental means, the relationship of reading and incidental vocabulary learning, and the strategies and tasks that promote the incidental learning of vocabulary. The findings show that L2 learners develop much of their vocabulary by incidental means through exposure to words in informative contexts. Moreover, this exposure is promoted by reading, and enhanced through multimodal glosses. Further research may focus on listening for higher lexical retention rates, the circumstances that allow incidental learning of multi-word phrases and collocations, and the use of technology-based methods for incidental vocabulary acquisition.

    To determine whether local bupivacaine injection into the incision site after gynecologic laparoendoscopic single site surgery (LESS) improves postoperative pain. This prospective cohort study included consecutive 158 patients who had LESS for benign adnexal disease from March 2013 to December 2015. Chronologically, 82 patients (March 2013 to August 2014) received no bupivacaine (group 1) and 76 (August 2014 to December 2015) received a bupivacaine block (group 2). For group 2, 10 mL 0.25% bupivacaine was injected into the 20 mm-incision site through all preperitoneal layers after LESS completion. Primary outcome is postoperative pain score using the visual analog scale (VAS). There was no difference in clinicopathological characteristics between the groups. Operating time (expressed as median [range], 92 [55-222] vs. 100 [50-185] minutes, P =0.137) and estimated blood loss (50 [30-1,500] vs. 125 [30-1,000] mL, P =0.482) were similar between the groups. Post-surgical VAS pain scores after 3 hours (3.5 [2-6] vs. 3.5 [2-5], P =0.478), 6 to 8 hours (3.5 [2-6] vs. 3 [1-8], P =0.478), and 16 to 24 hours (3 [2-4] vs. 3 [1-7], P =0.664) did not differ between groups. Bupivacaine injection into the trocar site did not improve postoperative pain after LESS. Randomized trials are needed to evaluate the benefits of local bupivacaine anesthetic for postoperative pain reduction.

    Most ocular adnexal lymphomas (OAL) are extranodal marginal zone B-cell lymphomas (EMZL) of mucosa-associated lymphoid tissue (MALT)-type. Chronic antigen stimulation has been suggested to have a pathogenetic role in EMZL and Chlamydia psittaci chronic infection has been recently associated with the development of OAL in a series of patients from Italy. To assess this association, an evaluation of the presence of C. psittaci was made in a different OAL population. DNA samples were obtained from formalin-fixed, paraffin-embedded sections samples of 26 patients with OAL, 20 non-OAL and 20 benign ocular lesions, diagnosed and treated between 1998 and 2003 at National Institute of Oncology in Havana, Cuba. All samples were histologically reviewed by an expert pathologist. Fluorescence in situ hybrization (FISH) analysis of translocations involving MALT1 was performed. The presence of bacterial DNA was assessed with a multiplex touchdown enzyme time release polymerase chain reaction. DNA sequencing was performed to confirm suspicious bands. Seventy-three percent of the OAL cases were EMZL and 81% were in stage IE. FISH analysis was performed in 13 OAL cases and none of them evidenced MALT1 translocations. DNA of C. psittaci was detected in 11% of the 46 lymphomas: two orbital EMZL and three non-OAL. All 20 benign ocular lesions were negative for C. psittaci. The low prevalence of C. psittaci in OAL suggests geographical differences in the etiology of this entity. International studies are needed to clarify the role of C. psittaci in OALs.

    Clear cell hidradenocarcinoma is a rare tumor of eccrine sweat gland origin that has a predilection for the head and neck. It has an indolent growth pattern and a higher incidence of regional and distant metastases. Metastasizing adnexal carcinomas are rare; thus, currently there is no uniform treatment guideline. We report a case of an 89-year-old female patient with clear cell hidradenocarcinoma manifesting in the right ear helix that metastasized to the right parotid gland who was treated by wide local excision and radiation therapy.

  4. Giant adrenal myelolipoma: Incidentaloma with a rare incidental association

    2010-01-01

    Full Text Available Adrenal myelolipoma is an unusual, benign and biochemically inactive tumor that is composed of mature adipose and hematopoietic tissue. It is usually diagnosed accidentally and nowadays much more frequently because of widespread use of ultrasonography, computed tomography (CT and magnetic resonance imaging. Adrenal myelolipoma is usually unilateral and asymptomatic, though known to be associated with obesity, hypertension, endocrinological disorders and some malignancies. We report herein two cases of right-sided giant adrenal myelolipoma diagnosed by multidetector-row CT. One patient was symptomatic because of a large mass in the right upper abdomen, which on imaging with CT was seen to be right adrenal myelolipoma. Another patient had a large left side Bochdalek hernia and right adrenal myelolipoma was incidentally discovered on CT.

    The cardiac structures are well seen on nongated thoracic computed tomography studies in the investigation and follow-up of cardiopulmonary disease. A wide variety of findings can be incidentally picked up on careful evaluation of the pericardium, cardiac chambers, valves, and great vessels. Some of these findings may represent benign variants, whereas others may have more profound clinical importance. Furthermore, the expansion of interventional and surgical practice has led to the development and placement of new cardiac stents, implantable pacemaker devices, and prosthetic valves with which the practicing radiologist should be familiar. We present a collection of common incidental cardiac findings that can be readily identified on thoracic computed tomography studies and briefly discuss their clinical relevance.

    Full Text Available Background: Skin adnexal tumors (SAT encompass wide spectrum of benign and malignant tumors that differentiate toward one or more adnexal structures found in normal skin. Overall incidence of SATs is low yet they can be challenging to diagnose. Aims: The aim of this study is to study the spectrum and microscopic features of SATs. Materials and Methods: It was a retrospective cross-sectional, descriptive study conducted over a period of 3 years. Formalin fixed, paraffin-embedded sections were stained with hematoxylin and eosin for histopathological analysis. Results: Out of the total 34,400 biopsies, 110 cases were diagnosed as SATs comprising 39.09% of tumors with follicular differentiation followed by tumors showing sweat gland differentiation (37.27%, and sebaceous differentiation (23.63%. The age ranged from 5 years to 85 years and male:female ratio was 1.03:1. Most of the tumors were benign (82.73% while only 17.27% were malignant. Pilomatricoma (28.2% was the most common benign tumor while sebaceous carcinoma (11.8% was the most common malignant tumor. Conclusion: Architectural features are of great importance in differentiating benign tumors from malignant.

    The calcification of knee ligaments is a finding noted only in a handful of case reports. The finding of an anterior cruciate ligament calcification has been reported once in the literature. Comparable studies involving the posterior cruciate ligament, medial collateral ligament and an ossicle within the anterior cruciate ligament are likewise discussed in reports of symptomatic patients. We report a case of incidentally discovered anterior cruciate ligament calcification. We discuss the likely etiology and clinical implications of this finding.

    The most common type of ocular lymphoma is non-Hodgkin lymphoma (NHL), categorized into two groups: indolent (slow growing) and aggressive (rapid growing). Differentiating benign reactive lymphoid hyperplasia (RLH) from malignant ocular adnexal lymphoma (OAL) is challenging. Histopathology, immunohistochemistry (IHC) and ow cytometry have been used as diagnostic tools in such cases. In this retrospective case series, from 2002 to 2013 at Farabi Eye Center, 110 patients with ocular lymphoproliferative disease were enrolled. Prevalence, anatomical locations, mean age at diagnosis and the nal diagnosis of the disease with IHC were assessed. Comparison between previous pathologic diagnoses and results of IHC was made. Immunoglobulin light chains and B-cell and T-cell markers and other immuno-phenotyping markers including CD20, CD3, CD5, CD23, CD10, CYCLIND1 and BCL2 were evaluated to determine the most accurate diagnosis. The lymphomas were categorized based on revised European-American lymphoma (REAL) classi cation. Mean age±SD (years) of the patients was 55.6 ±19.3 and 61% were male. Patients with follicular lymphoma, large B-cell lymphoma or chronic lymphocytic leukemia/small cell lymphoma (CLL/SLL) tended to be older. Nine patients with previous diagnoses of low grade B-cell lymphoma were re-evaluated by IHC and the new diagnoses were as follows: extranodal marginal zone lymphoma(EMZL) (n=1), SLL(n=1), mantle cell lymphoma (MCL) (n=3), reactive lymphoid hyperplasia RLH (n=2). Two cases were excluded due to poor blocks. Flow cytometry reports in these seven patients revealed SLL with positive CD5 and CD23, MCL with positive CD5 and CyclinD1 and negative CD23, EMZL with negative CD5,CD23 and CD10. One RLH patient was negative for Kappa/Lambda and positive for CD3 and CD20 and the other was positive for all of the light chains, CD3 and CD20. Orbit (49.1%), conjunctiva (16.1%) and lacrimal glands (16.1%) were the most common sites of involvement. Accurate

    To review the literature to determine the efficacy of available treatments for ocular adnexal lymphoma (OAL) and to evaluate the outcomes and complications of treatments in patients older than 13 years. A literature search was conducted last in March 2017 in the PubMed and Cochrane Library databases for English-language original research investigations that evaluated treatment outcomes for OAL. The searches identified 307 unique citations, and 27 studies were selected according to the criteria outlined for this assessment. The 27 studies reviewed comprised 2009 patients. Seventy-five percent of the cases reported were extranodal marginal zone lymphoma of mucosa-associated lymphoid tissue (MALT). Twenty-five studies reported results using radiotherapy with or without chemotherapy or surgery. The local control rate of MALT lymphomas with treatments involving radiotherapy averaged 95.9%. Distant and local relapses can occur, and in studies reporting only on MALT lymphomas (884 patients), the 5-year and 10-year disease-free survival rates were reported to be 86.4% and 78.7%, respectively. However, overall survival in patients receiving radiotherapy remained very good, with the 5-year and 10-year survival rates reported to be 93.8% and 84.9%, respectively. Studies that included data on multiple histologic subtypes of lymphoma or non-MALT lymphomas (988 patients) reported local control rates to be 93.1%; 5-year and 10-year disease-free survival rates to be 75.7% and 71.0%, respectively; and 5-year and 10-year overall survival rates to be 78.9% and 73.5%, respectively. Studies on the use of doxycycline for MALT lymphomas (137 patients) reported complete responses of between 4.4% and 13%. Complete and partial responses combined were between 26.7% and 65%. Disease-free survival was not reported for these 2 studies, although progression-free survival was reported to be between 55% and 60.9%. The most frequently reported complications of treatment were cataracts (12.1%) and

    This study prospectively assessed second-look ultrasound (US) for the evaluation of incidental enhancing lesions identified on preoperative breast magnetic resonance imaging (MRI). Between 2004 and 2007, 182 patients with malignant breast lesions detected on US and/or X-ray mammography and confirmed by cytology/histology underwent preoperative breast contrast-enhanced (CE)-MRI. Patients with incidental lesions on breast MRI underwent second-look high-resolution US directed at the site of the incidental finding. Diagnosis of incidental lesions was based on biopsy or 24-month follow-up. Breast MRI detected 55 additional lesions in 46/182 (25.2%) patients. Forty-two of 55 (76.3%) lesions were detected on second-look US in 38/46 (82.6%) patients. Malignancy was confirmed for 24/42 (57.1%) correlate lesions compared with 7/13 (53.8%) noncorrelate lesions. Second-look US depicted 8/9 (88.8%) Breast Imaging Reporting and Data System (BI-RADS) 5, 16/22 (72.7%) BI-RADS 4 and 18/24 (75%) BI-RADS 3 lesions. Sensitivity, specificity, accuracy and positive and negative predictive values for lesion detection/diagnosis was 100%, 88.9%, 94.6%, 90.3% and 100% for MRI and 64.3%, 70.4%, 67.3%, 69.2% and 65.5% for second-look US. Improved performance for US was obtained when masslike lesions only were considered. Second-look US is a confirmatory method for incidental findings on breast MRI, particularly for mass-like lesions.

    Full Text Available Ventricular pseudoaneurysm is an uncommon, potentially fatal complication that has been associated with myocardial infarction, cardiac surgery, chest trauma, and infectious processes. Diagnosis can be challenging, as cases are rare and slowly progressing and typically lack identifiable features on clinical presentation. As a result, advanced imaging techniques have become the hallmark of identification. Ahead, we describe a patient who presents with acute decompensated heart failure and was incidentally discovered to have a large right ventricular pseudoaneurysm that developed following previous traumatic anterior rib fracture.

    We present the case of a 45-year-old man with a long-standing history of a slow-growing left submandibular mass. Imaging was diagnostic as it disclosed an absent orthotopic thyroid gland and heterogeneous masses, with both solid and cystic components, as well as calcifications in the left sublingual/submandibular space and in the left paramedian aspect of the tongue base, consistent with double thyroid ectopia, originating from central and lateral thyroid anlages, respectively. Pathology confirmed an ectopic thyroid goiter in the left submandibular space with an incidental papillary microcarcinoma. Scintigraphy also demonstrated ectopic thyroid tissue in the left tongue base. (orig.)

    Adnexal tumors of the skin are a large and diverse group of benign and malignant neoplasms, which exhibit morphological differentiation toward one of the different types of adnexal epithelium present in normal skin and they pose a diagnostic challenge. The purpose of this study is to share our experience with these rare but aggressive tumors at a tertiary care cancer hospital in a developing country. A retrospective review of 11 patients diagnosed with rare adnexal tumors and their variants from January 2005 to December 2014, treated either surgically or non-surgically, was performed to describe the clinicopathological characteristics and outcome of the disease. A total of 11 patients were diagnosed with adnexal carcinoma and its variants: a 34-year-old Sindhi man, a 59-year-old Punjabi woman, a 32-year-old woman from Khyber Pakhtunkhwa, a 43-year-old Punjabi woman, a 64-year-old Punjabi man, a 51-year-old man from Khyber Pakhtunkhwa, a 51-year-old Punjabi woman, a 74-year-old Punjabi woman, a 75-year-old Punjabi man, a 61-year-old man from Khyber Pakhtunkhwa, and a 53-year-old man from Khyber Pakhtunkhwa. The male to female ratio was 1.2:1. The histological variations were sebaceous differentiation (n = 4), microcystic adnexal carcinoma (n = 4), trichilemmal carcinoma (n = 1), pilomatrix carcinoma (n = 1), and hidradenocarcinoma (n = 1). The mean age at presentation was 54 years (range 32 to 75). The primary subsite of involvement was the scalp in nine patients followed by eyelids in two patients. Surgery was the primary treatment modality in almost all patients; postoperative radiotherapy (PORT) was offered to eight patients. The median dose of radiation was 45 Gy to the primary site. Indications for radiotherapy included close margins (n = 2), positive margins (n = 1), high grade histology (n = 4), and multifocal disease (n = 1). On follow-up, two patients presented with local, one regional and two patients developed distant metastasis. Adnexal carcinomas are

    2015-06-01

    Extra-adrenal myelolipomas are rare, benign tumors composed of adipose tissue and hematopoietic cells. Almost all myelolipomas occur within the adrenal gland. Only 50 cases of myelolipomas were described in literature and none of these were associated with gastric mesenchymal neoplasia. A 72-year-old male patient presented to a family medicine outpatient clinic with dyspnea and urinary urgency. His abdominal sonography revealed a 9-cm intra-abdominal mass. An incidental finding was 2 separate masses 1 cm each on the serosal surface of the stomach. The pathology specimen of the retroperitoneal mass revealed myelolipoma histopathology while gastric masses were reported as spindle cell mesenchymal neoplasias. The association of gastric spindle cell tumor and myelolipoma was not reported before in medical literature. Extra-adrenal myelolipomas are rare lesions, but should be considered in the differential diagnosis of fat containing retroperitoneal masses that are well circumscribed.

    Incidental emotions, which are irrelevant to the current decision, play a significant role in the decision-making process. In this study, to investigate the influence of incidental emotions on behavioral, psychological, and electrophysiological responses in the process of decision making, participants were required to perform a monetary gambling task. During the selection stage, an emotional picture, which was chosen from the Chinese Affective Picture System and fell into one of three categories: negative, neutral, and positive, was presented between two alternatives (small/large amount of bet). The pictures were provided to induce incidental emotions. ERPs and self-rating emotional experiences to outcome feedback were recorded during the task. Behavioral results showed that positive incidental emotions elicited risk preference, but emotional experiences to outcome feedback were not influenced by incidental emotions. The feedback-related negativity amplitudes were larger in the positive emotion condition than in the negative and neutral emotion conditions for small outcomes (including wins and losses), whereas there was no difference between the three conditions for large outcomes. In addition, the amplitudes of P3 were reduced overall in the negative emotion condition. We suggest that incidental emotions have modulated both the option assessment stage (manifested in behavioral choices) and the outcome evaluation stage (manifested in ERP amplitudes) of decision making unconsciously (indicated by unchanged subjective emotional experiences). The current findings have expanded our understanding of the role of incidental emotion in decision making. © 2016 Society for Psychophysiological Research.

    Radiologists frequently report orthopantomograms (OPTs) and other views of the mandible, most often in patients who have suffered facial trauma. These examinations may reveal incidental pathology. It is important that radiologists are aware of the radiological appearances and the clinical significance of these lesions. In this review we will present examples of the more common odontogenic lesions including: radicular cyst, odontogenic keratocyst, dentigerous cyst, ameloblastoma, and also examples of non-odontogenic pathology: bisphosphonate-related osteonecrosis of the jaw (BRONJ) and chronic osteomyelitis. Although some of the lesions will require computed tomography (CT) or magnetic resonance imaging (MRI) for further lesion characterization and evaluation of the surrounding tissues, we are going to focus on the plain film appearances. We will also briefly discuss the pathogenesis, epidemiology, and treatment of these lesions.

    This document addresses the incidental reflector reactivity worth of containerized fire extinguishing agents authorized for use in PF-4 at Los Alamos National Laboratory (LANL). The intent of the document is to analyze dry fire extinguishing agent that remains in a container and is not actively being used in a fire emergency. The incidental reflector reactivity worth is determined by comparison to various thicknesses of close fitting water reflection which is commonly used to bound incidental reflectors in criticality safety evaluations. The conclusion is that even in unlimited quantities, when containerized the authorized dry fire extinguishing agents are bound by 0.4 inches of close fitting water.

    Desmoplastic trichoepithelioma (DTE), morpheaform basal cell carcinoma (BCC) and microcystic adnexal carcinoma (MAC) are sclerosing adnexal neoplasms with overlapping histopathologic features. We compared cytokeratin 15, (CK15), T-cell death-associated gene 51 (TDAG51), cytokeratin 20 (CK20) and androgen receptor (AR) in differentiating these tumors and assessed their expression in BCC subtypes. Fifteen DTE, 15 infundibulocystic BCC, 18 micronodular BCC, 18 morpheaform BCC and 6 MAC were assessed for CK15, TDAG51, CK20 and AR expression. Quantitative CK15 staining was higher in DTE compared with BCC (p < 0.0001) and MAC (p = 0.02). Quantitative TDAG51 staining was higher in DTE than BCC (p < 0.0001). The CK20+AR- immunophenotype was 100% sensitive and specific in diagnosing DTE. The CK20-AR+ immunophenotype was 95.24% specific and 83.33% sensitive for BCC. The CK20-AR- immunophenotype was 83.33% sensitive and 90.91% specific for MAC. CK15, CK20 and AR were positive in 87, 53 and 67% of infundibulocystic BCC cases, respectively. Combination of CK20 and AR best differentiated these sclerosing adnexal neoplasms. Greater positivity for CK15 and TDAG51 generally favors benign lesions. Infundibulocystic BCC has higher CK20 and lower AR immunopositivity than other BCC variants and a high degree of CK15 and TDAG51 positivity. © 2015 John Wiley & Sons A/S.

    Full Text Available Gastrointestinal stromal tumors (GIST are mesenchymal tumors located primarily in the gastrointestinal tract. We aimed to present a case report of GIST incidentally detected during laparoscopic cholecystectomy.A 60-year-old woman was admitted to the emergency room due to abdominal pain for one day. The physical examination revealed sensitivity on the right upper quadrant. In the laboratory examinations, white blood cell count 6,490 k/uL, hemoglobin 12 g/dL, hematocrit 35% and other biochemical tests were normal. Abdominal ultrasound revealed hydropic gallbladder, several gallstones with a maximum diameter of 15 mm and pericholecystic fluid collection was present. Laparoscopic cholecystectomy was planned due to acute cholecystitis. In exploration, beside the presence of acute cholecystitis, a mass of approximately 5 cm, located 15 cm distal to the ligament of Treitz was detected. Laparoscopic cholecystectomy was performed. Conversion to open laparotomy was done; small intestine resection with end-to-end anastomosis was performed. Gastrointestinal stromal tumor with CD117, CD34 and S100 positivity was detected on histopathologic examination.It is thought that GISTs are mesenchymal tumors originating from precursors of Kajal cells. GISTs are usually detected in their 60s. The first option for treatment is surgical resection.

    Concern for a diminished human experience of nature and subsequent decreased human well-being is addressed via a consideration of green infrastructure's potential to facilitate unplanned or incidental nature experience. Incidental nature experience is conceptualized and illustrated in order...... to consider this seldom addressed aspect of human interaction with nature in green infrastructure planning. Special attention has been paid to the ability of incidental nature experience to redirect attention from a primary activity toward an unplanned focus (in this case, nature phenomena). The value...... of such experience for human well-being is considered. The role of green infrastructure to provide the opportunity for incidental nature experience may serve as a nudge or guide toward meaningful interaction. These ideas are explored using examples of green infrastructure design in two Nordic municipalities...

    Full Text Available Background:To determine the prevalence of incidental Kienböck disease.   Methods: A retrospective analysis of 150,912 radiological reports or images obtained over a five year period was performed of 76,174 patients who underwent a radiograph or computed tomography scan which included the wrist, in Edinburgh and Lothian, UK. Results: There were 5 cases of incidental Kienböck disease and 13 cases of symptomatic Kienböck disease. There were no significant differences in age, sex, ethnicity, comorbidities, smoking status, excess alcohol use or Lichtman stage between the incidental and symptomatic Kienböck groups. Conclusion: The radiological prevalence of incidental Kienböck disease was 0.0066% or 7 in 100,000 patients.

  11. Cooperative Research to Evaluate an Incidental Catch Distribution Forecast

    2017-05-01

    Full Text Available Concern over incidental catches in commercial fisheries has been increasing, and while simple mitigation strategies have been effective, few effective mitigation strategies have been established for more complex species interactions. Incidental catches of alewife (Alosa pseudoharengus and blueback herring (A. aestivalis in the commercial Atlantic herring (Clupea harengus fishery have received substantial attention on the Northeast U.S. continental shelf, despite an existing bycatch avoidance program. This study evaluates the utility of existing species distribution forecasts to predict river herring catches in the southern New England small mesh bottom trawl Atlantic herring fishery, with the ultimate goal of incorporating incidental catch forecasts into the bycatch avoidance program. Commercial Atlantic herring bottom trawl vessels assisted with field-based evaluation of alewife, blueback herring, and Atlantic herring species distribution forecast models. Vessels were equipped with conductivity, temperature, and depth probes, and sampling occurred throughout the fishery season (January–March. Locations of expected low and high forecasted incidental catches were sampled, as well as locations the captain expected to find low and high incidental catches. This allowed us to sample within the spatial area the fishery occurs, and to evaluate the forecasted conditions, and predictions, at the spatial scale of the fishery. Catch differences between high and low probability stations were small and variable, as were differences in modeled probability of species presence. No differences were observed between observations at model-predicted stations and captain-selected stations. The sampling provided a better understanding of the potential effectiveness of distribution forecasts for further reducing incidental catches. Existing models have limited use at the spatial scale of this fishery, but could be improved by developing models with fishery

The immunological functions of the spleen and its role against infections are well defined, so the removal of this organ due to incidental injuries favors the appearance of infections in these patients for the rest of their lives. Of the 77 incidental injuries 47 (61 % incidental splenectomies and 30 (39 % conservative surgeries were performed. Duodenal ulcer and hiatal hernia proved to be the main causes of incidental splenectomy. There were 11 infections (23.4 % and 1 death (2.1 % in the incidental splenectomy compared with 1 infection (3.3 % and no death in the conservative surgery. It is concluded that splenectomy is not justified because of its disadvantages

  13. Incidental mood state before dissonance induction affects attitude change.

    Directory of Open Access Journals (Sweden)

    Marie-Amélie Martinie

    Full Text Available The way that incidental affect impacts attitude change brought about by controlled processes has so far been examined when the incidental affective state is generated after dissonance state induction. We therefore investigated attitude change when the incidental mood occurs prior to dissonance state induction. We expected a negative mood to induce systematic processing, and a positive mood to induce heuristic processing. Given that both systematic processing and attitude change are cognitively costly, we expected participants who experienced the dissonance state in a negative mood to have insufficient resources to allocate to attitude change. In our experiment, after mood induction (negative, neutral or positive, participants were divided into low-dissonance and high-dissonance groups. They then wrote a counterattitudinal essay. Analysis of their attitudes towards the essay topic indicated that attitude change did not occur in the negative incidental mood condition. Moreover, written productivity-one indicator of cognitive resource allocation-varied according to the type of incidental mood, and only predicted attitude change in the high-dissonance group. Our results suggest that incidental mood before dissonance induction influences the style of information processing and, by so doing, affects the extent of attitude change.

In our experiment, after mood induction (negative, neutral or positive), participants were divided into low-dissonance and high-dissonance groups. They then wrote a counterattitudinal essay. Analysis of their attitudes towards the essay topic indicated that attitude change did not occur in the negative incidental mood condition. Moreover, written productivity-one indicator of cognitive resource allocation-varied according to the type of incidental mood, and only predicted attitude change in the high-dissonance group. Our results suggest that incidental mood before dissonance induction influences the style of information processing and, by so doing, affects the extent of attitude change.

    Syphilis is a rare disease in the rectum. It is difficult to diagnose because the characteristics of the rectal syphilis rectal lesion are highly varied. The endoscopic findings of rectal syphilis are proctitis, ulcers, and masses. If rectal syphilis is suspected to be the cause for rectal lesions, it is important for physicians to consider the sexual history and sexual orientation of the patient. We report a case of incidental rectal syphilis in a 41-year-old man diagnosed during a regular medical check-up.

    Ultrasonography is a safe, nonivasive examination which should be the first procedure in the workup of a patient with a definite or suspected pelvic mass. The diagnostic schemes were derived from correlating the sonographic features with histomorphology in 230 surgically proven pelvic masses. Besides separating pelvic masses into the conventional categories of cystic, complex and solid, grayscale sonographic features of a pelvic mass can be used to subcategorized these masses into a more useful differential diagnosis. The results are as follows: 1. The most characteristic finding of uterine mynoma was midly to mederately echogenic uterine enlargement (90.7%) with a lobulated uterine margin (62.8%), and often less echogenic than the normal uterine echoes. 2. The typical ultrasonographic finding of H-mole was uterine enlargement with multiple small vesicular patterns of intrauterine contents (93%). 3. This most frequent finding of cystic teratoma was cystic mass with echogenic foci (48%), but the echogenic appearance of the lesions was extremely variable. 4. The ultrasonographic findings of ectopic pregnancy were adnexal mass (complex or cystic), decidual proliferation of the uterus, enlargement of uterine size, fluid in cul-de-sac, deveiation of uterus by adnexal mass, and pseudointrauterine appearance. 5. Ultrasound provided information leading to the correct diagnosis in 57% of cases, contributory data in 21.3%, and non-specific information in 10.4%. Errors occured in 3.9% and false -negative in 7.4%

    This study is an attempt to explore the difference between acquiring new words with different semantic fields to which they belong. In other words, the purpose of this study is to scrutinize the contribution of semantic field theory in learning new vocabulary items in an EFL setting. Thirty-eight students of three different levels of education took part in this research. They were exposed to some new words from four different semantic fields, and then they were tested on their acquisition of the words meaning. This exposure was through reading texts and the aim of reading was just comprehension, therefore the words were acquired incidentally. The outcome showed significant differences between groups with different levels of education regarding retention of words from different semantic fields.

  20. Color vision and fatigue: an incidental finding.

    Hovis, Jeffery K; Ramaswamy, Shankaran

    2007-11-01

    Because there is little information available as to how fatigue and color vision interact, we present some incidental findings on how a protanope and a color-normal perform on several color vision tests after 1 night of sleep deprivation. A series of clinically and occupationally based color vision tests were administered to a protanope and a color-normal subject after they had stayed awake all night and after a regular night's sleep. There was essentially no change in their performance on the clinical color vision tests; however, both did worse on the occupationally based color vision tests after 1 night of sleep deprivation. The color-normal made numerous errors in identifying colors displayed on a video display terminal, whereas the protanope had a large increase in errors on the CN Lantern Test. Both subjects passed these respective tests after a regular night's sleep. The primary reason for color-normal's poor performance on the video display terminal test was probably due to a decrement in his visuo-motor control rather than a loss in color discrimination. In contrast, the protanope's poor performance on the lantern test was probably due to the additive effects of the inherent limitations of his visual system and fatigue.

    The objective of this study was to analyze the incidence and treatment options of occult cancer or atypical lesions found in the histopathological examination of reduction mammoplasty (RM) specimens. The role of preoperative mammography and systematic histopathological examination are discussed. We performed a retrospective single-center database review of all patients who underwent a RM between January 2005 and December 2014. Preoperative examination, histopathological findings and follow-up were documented. A total of 1045 patients underwent RM, of which 97% were bilateral (1021). All patients received a mammography and routine clinical examination to exclude cancer preoperatively. The overall mean patient age was 40.2 years (14.2-73.4). A total of 19 patients (1.18%) had significant histopathological findings, all of whom were over 40 years of age. There were 4 incidental carcinomas (0.38%), of which 2 were DCIS (0.19%) and 2 invasive ductal carcinomas (0.19%). Incidence of postoperative diagnosis of occult breast cancer in RM specimens remains low, but poses significant therapeutic challenges. While emphasis should lay on preoperative diagnostics, routine histological analysis of RM specimens is recommended.

    The opacification the mastoid cavity is frequently reported by radiologists on cross-sectional imaging done for non-otological indications. It is well known that presence of fluid the mastoid does not amount to mastoiditis. This study seeks to provide an evidence-based confirmation of this known finding. The purpose of our study was to determine the prevalence of mastoid opacification in children undergoing outpatient brain MRI examination. Our study included 515 outpatient children who had brain MRI for indications other than mastoiditis or otitis media from January 2014 to March 2014. Children with history of skull base trauma or radiation were excluded. The age range was 15 days to 18 years. The overall prevalence of mastoid opacification was determined using one sample proportion and exact 95% Clopper-Pearson confidence intervals. The prevalence of mastoid opacification was analyzed based on gender, age and presenting symptoms using chi-square test of association. One hundred ten children (21.4%) had mastoid opacification. Younger patients tended to have higher opacification rates with the prevalence in children younger than 1 year of age and between 1 and 2 years of age as high as 41.7% (20/48) and 47.5% (38/80), respectively. The diagnosis of mastoiditis in children should not be based upon a radiologist's report of finding fluid or mucosal thickening in the mastoid air cells as incidental opacification the mastoid is seen frequently.

    Concern for a diminished human experience of nature and subsequent decreased human well-being is addressed via a consideration of green infrastructure's potential to facilitate unplanned or incidental nature experience. Incidental nature experience is conceptualized and illustrated in order to consider this seldom addressed aspect of human interaction with nature in green infrastructure planning. Special attention has been paid to the ability of incidental nature experience to redirect attention from a primary activity toward an unplanned focus (in this case, nature phenomena). The value of such experience for human well-being is considered. The role of green infrastructure to provide the opportunity for incidental nature experience may serve as a nudge or guide toward meaningful interaction. These ideas are explored using examples of green infrastructure design in two Nordic municipalities: Kristianstad, Sweden, and Copenhagen, Denmark. The outcome of the case study analysis coupled with the review of literature is a set of sample recommendations for how green infrastructure can be designed to support a range of incidental nature experiences with the potential to support human well-being.

    Full Text Available Objective. To evaluate clinical characteristics and outcomes in incidentally detected lung cancer and in symptomatic lung cancer. Material and Methods. We designed a retrospective study including all patients undergoing pulmonary resection with a curative intention for NSCLC. They were classified into two groups according to the presence or absence of cancer-related symptoms at diagnosis in asymptomatic (ASX—incidental diagnosis—or symptomatic. Results. Of the 593 patients, 320 (53.9% were ASX. In 71.8% of these, diagnosis was made by chest X-ray. Patients in the ASX group were older (P=0.007, had a higher prevalence of previous malignancy (P=0.002, presented as a solitary nodule more frequently (P<0.001, and were more likely to have earlier-stage disease and smaller cancers (P=0.0001. A higher prevalence of incidental detection was observed in the last ten years (P=0.008. Overall 5-year survival was higher for ASX (P=0.001. Median survival times in pathological stages IIIB-IV were not significantly different. Conclusion. Incidental finding of NSCLC is not uncommon even among nonsmokers. It occurred frequently in smokers and in those with history of previous malignancy. Mortality of incidental diagnosis group was lower, but the better survival was related to the greater number of patients with earlier-stage disease.

    1984-01-01

    Ultrasonography is most common utilized diagnostic tool in obstetric and gynecology for the evaluation of patient with a pelvic mass or pregnancy. For it is characterized by no radiation hazard, noninvasive examination and high diagnostic accuracy. Also it affords an accurate assessment of the presence, size, location and internal consistency of a pelvic mass. The recent availability and improved resolution of realtime scanning have afforded a more flexible and complete approach to evaluation of normal and abnormal structures in the pelvis. We analyzed ultrasonographic findings in 154 pathologically proven cases of pelvic mass examined at Korea General Hospital from January 1983 to April 1984. The results were as follows: 1. The age distribution was from 12 years to 66 years and the majority of patients were between the ages of 21 and 51 years (91.4%). 2. The incidence of pelvic mass was 27.9% in uterine leiomyoma, 22.7% in ovarian cyst, 13.0% in adenomyosis and 8.4% in serous cystadenoma. 3. Mild to moderately echogenic nodular uterine enlargement with some cystic change (81.4%) of leiomyoma and multiple small vesicular pattern of intrauterine contents with uterine enlargement of H-mole were the most common ultrasonographic findings. The location and type of leiomyoma were most common in the fundus and body (95.3%), and intramural myoma (53.5%). The most frequent findings of ovarian teratoma was cystic mass with echogenic focus (41.7%) but the echogenic appearance of the lesions was extremely variable.The ultrasonographic findings of ectopic pregnancy were cystic or complex adnexal mass (80.0%), with or without fluid in cul-de-sac and deviation of uterus by adnexal mass. 4. Accuracy of ultrasonography i determining the overall correct diagnosis of the pelvic masses compared with proven diagnosis was approximately 61.7%. The diagnostic accuracy was 90.7% in uterine leiomyoma, 100% in H-mole and 80.0% in ectopic pregnancy.

    Full Text Available This article characterizes the opinions of patients and family members of patients undergoing clinical genomic-based testing regarding the return of incidental findings from these tests. Over sixteen months, we conducted 55 in-depth interviews with individuals to explore their preferences regarding which types of results they would like returned to them. Responses indicate a diversity of attitudes toward the return of incidental findings and a diversity of justifications for those attitudes. The majority of participants also described an imperative to include the patient in deciding which results to return rather than having universal, predetermined rules governing results disclosure. The results demonstrate the importance of a patient centered-approach to returning incidental findings.

    Human subject research involving brain imaging is likely to reveal significant incidental findings of abnormal brain morphology. Because of this fact and because of the fiduciary relationship between researcher and subject, board-certified or board-eligible radiologists should review the scans to look for any abnormality, the scans should be conducted in accordance with standard medical practice for reviewing the clinical status of the whole brain, and the informed consent process should disclose the possibility that incidental findings may be revealed and what consequences will follow. In the event such findings are revealed, qualified physicians should explain to the subject the significance of the findings and the alternatives available.

  12. Partial spline score test to determine if tumors are incidental

    International Nuclear Information System (INIS)

    Griffith, W.C.

    1994-01-01

    A primary consideration in many rodent bioassays is whether a tumor observed in an animal has affected its life span. When tumors are incidental, the natural death times can be regarded as random sampling times unrelated to the presence of the tumor. In this case, animals dying from natural causes and those sacrificed can be combined to estimate the prevalence p(t) of the tumors in the living animals. When tumors are incidental, the tumor incidence rate, λ T (t), is related to the prevalence by λ T (t) = p(t) 1 - p(t) , where p(t) is the derivative of the prevalence

    Full Text Available Testicular plasmacytomas are a rare phenomenon reported in the literature and they can occur as a solitary plasmacytoma, as a recurrence of multiple myeloma, or concurrently in an active myeloma. We report the case of a 43-year-old man who presented with back pain and was diagnosed with multiple myeloma. A CT scan performed to determine the extent of disease revealed an incidental mass in the testicle. Immunohistochemical staining of the mass revealed monoclonal cytolpasmic IgA in the tumor cells and serum studies showed this same immunoglobulin. Following orchiectomy, radiotherapy to the vertebra, chemotherapy with bortezomib, dexamethasone, and doxorubicin, and an autologous bone marrow transplant, the patient is alive twelve months after diagnosis and is in complete remission.

    Full Text Available Bilateral cryptorchidism is a rare occurrence and seminoma is the most common germ cell tumor found in undescended testes when they occur. We present the case of a patient with bilateral cryptorchidism who presented to our trauma center after a motor vehicle collision and was found incidentally to have a 17-cm intra-abdominal mass. The mass was subsequently biopsied and proven to be seminoma. The patient completed three cycles of bleomycin/etoposide/cisplatin chemotherapy and successfully underwent a postchemo retroperitoneal lymph node dissection with no viable residual tumor or positive lymph nodes found in the surgical specimen. He also had an orchiopexy of the contralateral testicle. The patient recovered fully and has been found to be recurrence-free four months postoperatively. We highlight the importance of cisplatin-based chemotherapy and extensive tumor resection as the mainstay of initial cancer control.

  19. p75 Neurotrophin receptor differentiates between morphoeic basal cell carcinoma and desmoplastic trichoepithelioma: insights into the histogenesis of adnexal tumours based on embryology and hair follicle biology.

    Science.gov (United States)

    Krahl, D; Sellheyer, K

    2010-07-01

    Tumour development is frequently described in the basic pathology literature as a recapitulation of embryogenesis. However, a link between the embryology of the skin and the histogenesis of adnexal tumours has been largely overlooked. The low-affinity p75 neurotrophin receptor (p75NTR) has a profound role in hair follicle biology. We therefore speculated that it is involved in the histogenesis of follicular adnexal tumours. One of the most challenging diagnoses in dermatopathology is differentiating morphoeic basal cell carcinoma from desmoplastic trichoepithelioma. To describe the expression pattern of p75NTR during cutaneous embryogenesis, in the adult hair follicle and in morphoeic basal cell carcinoma and desmoplastic trichoepithelioma. Evaluation of the staining pattern for p75NTR was performed using standard immunohistochemical techniques. For comparison, we examined staining for cytokeratin 20 which highlights Merkel cells. All 17 desmoplastic trichoepitheliomas were immunoreactive with > 80% of the cells stained, whereas 12 of the 14 (86%) morphoeic basal cell carcinomas were p75NTR negative. In the two positive cases of morphoeic basal cell carcinoma basal cell carcinoma favours a concept of this tumour as a more primitive follicular lesion with the characteristics of a carcinoma and not a hamartoma. We suggest including p75NTR as a tool in the differential diagnosis between morphoeic basal cell carcinoma and desmoplastic trichoepithelioma.

    2013-09-01

    Appendiceal mucocele is a rare disease (0.2-0.3% of all appendectomies) and it is defined as abnormal accumulation of mucoid material in the appendiceal lumen. Almost half of the patients are asymptomatic. The most common clinical manifestation is pain and palpable mass in the right iliac fossa, which is difficult to differentiate from the malignant or benign adnexal masses. By presenting our three cases, we would like to draw attention to the diagnostic difficulties of the pain and palpable mass in the right lower abdominal region.

They were classified into two groups according to the presence or absence of cancer-related symptoms at diagnosis in asymptomatic (ASX)—incidental diagnosis—or symptomatic. Of the 593 patients, 320 (53.9%) were ASX. In 71.8% of these, diagnosis was made by chest X-ray. Patients in the ASX group were older (P = 0.007), had a higher prevalence of previous malignancy (P = 0.002), presented as a solitary nodule more frequently (P ASX (P = 0.001). Median survival times in pathological stages IIIB-IV were not significantly different. Incidental finding of NSCLC is not uncommon even among nonsmokers. It occurred frequently in smokers and in those with history of previous malignancy. Mortality of incidental diagnosis group was lower, but the better survival was related to the greater number of patients with earlier-stage disease.

  16. The Incidental Thyroid Lesion in Parathyroid Disease Management

    Directory of Open Access Journals (Sweden)

    Uthman Alamoudi MD

    2017-03-01

    Full Text Available Objective The incidental thyroid lesion is a common finding during general imaging studies. Their management has been the subject of numerous studies and recommendations. Parathyroid disease workup necessitates imaging investigation of the adjacent thyroid gland and therefore provides a unique window to the perioperative management of thyroid incidentaloma. The specific prevalence of incidental thyroid lesions in the context of parathyroid disease is unknown. We seek to investigate its prevalence during parathyroid workup and surgery and to ascertain if there was a change in management of these patients. Study Design Five-year retrospective database review. Setting Tertiary care medical center. Subjects and Methods The source and indication for referral, preoperative investigation findings, and management of the incidental thyroid lesions were examined. The actual procedure performed and final pathology results were assessed. Results A total of 98 patients and 106 operations, including revision surgeries, were identified. There were 21 incidental thyroid lesions (21.4% detected, whereby 15 patients underwent fine-needle aspirations and 12 subsequently had diagnostic hemithyroidectomies. This decision was made preoperatively in 5 patients and intraoperatively in 7 patients at the time of parathyroid surgery. Along with other pathologies, there were 7 patients with micropapillary thyroid carcinoma identified. Conclusions In our series, the prevalence of incidental thyroid lesion and thyroid malignancy is comparable to the general population. The management of the initial parathyroid disease in our patients was altered by the imaging and cytological findings of these thyroid lesions. This has implications on perioperative counseling of the thyroid and parathyroid disease.

    Conventional projection radiography (chest x-ray) is one of the most frequently requested procedures in radiology. Even though chest x-ray imaging is frequently performed in asymptomatic patients for preoperative assessment, clinically relevant incidental findings are relatively scarce. This is due to the relatively low sensitivity of chest x-rays where few clinically relevant incidental findings are to be expected, as any detectable pathologies will as a rule already be clinically symptomatic. Recommendations from relevant societies for the management of incidental findings, apart from the clarification of incidental nodules, do not exist. This review article therefore describes the most frequent and typical incidental findings of lung parenchyma (apart from pulmonary nodules), mediastinal structures including the hilum of the lungs, pleura, chest wall and major vessels. Also described are those findings which can be diagnosed with sufficient certainty from chest x-rays so that further clarification is not necessary and those which must be further clarified by multislice imaging procedures or other techniques. (orig.) [German] Eine der haeufigsten Untersuchungen in der Radiologie ist die konventionelle Projektionsradiographie des Thorax (Roentgenthorax). Auch wenn projektionsradiographische Aufnahmen im Rahmen einer praeoperativen Abklaerung haeufig als orientierende Untersuchung angefertigt werden, sind - bedingt durch die relativ geringe Sensitivitaet des Roentgenthorax - wenig klinisch relevante Zufallsbefunde zu erwarten, da nachweisbare Pathologien in der Regel bereits auch klinisch apparent sind. Empfehlungen entsprechender Fachgesellschaften zu Zufallsbefunden im Roentgenthorax jenseits der Abklaerung von Rundherden liegen nicht vor. Die vorliegende Arbeit beleuchtet daher haeufige und typische Zufallsbefunde des Lungenparenchyms (ausser den Lungenrundherden), der mediastinalen Strukturen einschliesslich der Hili, der Pleura, der Thoraxwand sowie der

    We employed eye-tracking to investigate how performing different tasks on scenes (e.g., intentionally memorizing them, searching for an object, evaluating aesthetic preference) can affect eye movements during encoding and subsequent scene memory. We found that scene memorability decreased after visual search (one incidental encoding task) compared to intentional memorization, and that preference evaluation (another incidental encoding task) produced better memory, similar to the incidental memory boost previously observed for words and faces. By analyzing fixation maps, we found that although fixation map similarity could explain how eye movements during visual search impairs incidental scene memory, it could not explain the incidental memory boost from aesthetic preference evaluation, implying that implicit mechanisms were at play. We conclude that not all incidental encoding tasks should be taken to be similar, as different mechanisms (e.g., explicit or implicit) lead to memory enhancements or decrements for different incidental encoding tasks.

  19. Incidentally Detected Inoperable Malignant Pheochromocytoma with Hepatic Metastasis Treated by Transcatheter Arterial Chemoembolization

    2014-12-01

    Full Text Available Malignant pheochromocytoma (PCC is a rare condition. Although the liver is the second most frequent site of metastasis in malignant PCC, no definite treatments have been established. Herein, we report a case of liver metastasis of PCC that was successfully treated by transcatheter arterial chemoembolization (TACE. A 69-year-old man was admitted to the Department of Gastroenterology for evaluation of an incidental hepatic mass in August 2013. He had undergone right adrenalectomy in May 2005 and PCC had been confirmed on the basis of histopathological findings. Liver biopsy was performed, and metastatic PCC was diagnosed. The lesion appeared inoperable because of invasion of the portal vein and metastases in the lymph nodes along the hepatoduodenal ligament. Thus, TACE was performed instead. After TACE, symptoms including dizziness and cold sweating improved, and the patient's serum catecholamine levels decreased. On the basis of this case, we believe that TACE may be a useful treatment for liver metastasis in malignant PCC.

    Full Text Available Purpose. To report a case of successful thrombolysis performed in a patient with an incidental unruptured intracranial aneurysm and review the literature. Case Report. Patient admitted for ischemic stroke due to left posterior cerebral artery occlusion, with an incidental right middle cerebral artery aneurysm, who underwent treatment with tissue plasminogen activator (rtPA resulting in clinical improvement without complications. Conclusion. The presence of unruptured intracranial aneurysms is considered as a contraindication to thrombolysis, due to a potentially higher hemorrhagic risk of aneurysm rupture. Patients, otherwise, eligible for thrombolysis are usually excluded from receiving this emergent treatment, despite its potential benefits. A reevaluation of the strict exclusion criteria for thrombolysis in acute stroke patients should be considered.

  2. Incidental findings, genetic screening and the challenge of personalisation

    2014-12-01

    Full Text Available Genetic tests frequently produce more information than is initially expected. Several documents have addressed this issue and offer suggestions regarding how this information should be managed and, in particular, concerning the expedience of revealing (or not revealing it to the persons concerned. While the approaches to the management of these incidental findings (IFs vary, it is usually recommended that the information be disclosed if there is confirmed clinical utility and the possibility of treatment or prevention. However, this leaves unsolved some fundamental issues such as the different ways of interpreting "clinical utility", countless sources of uncertainty and varying ways of defining the notion of "incidental". Guidelines and other reference documents can offer indications to those responsible for managing IFs but should not be allowed to relieve researchers and healthcare professionals of their responsibilities.

    2014-01-01

    Aim: To assess the prevalence and the department's detection rate of adrenocortical hyperplasia. Materials and methods: All computed tomography (CT) examinations of the adrenal glands between February and April 2011 were reviewed. The study excluded patients with known underlying cancer, abdominal trauma, or endocrine disease. The adrenal gland was deemed enlarged if its body was greater than 10 mm diameter, or a limb greater than 5 mm. Results: There were a total of 564 eligible CT studies during this period. A total of 64 cases of incidental adrenal enlargement were found giving a prevalence of 11.3%. Only nine cases were reported in the contemporaneous CT report. Conclusion: The results of the present study show that incidental adrenal enlargement has a significant prevalence. It is often dismissed during reporting, and awareness needs to be raised in the radiological community. Equally, the clinical and biochemical significance needs to be assessed with endocrine correlation

    An appendicolith-related appendiceal obstruction leading to appendicitis is a commonly encountered surgical emergency that has clear evidence-based management plans. However, there is no consensus on management of asymptomatic patients when appendicoliths are found incidentally. The objective of this study was to determine the risk of appendicitis in patients with an incidental finding of the appendicolith. A retrospective matched cohort study of patients with appendicolith discovered incidentally on computed tomographic scan from January 2008 to December 2014 at our institution was completed. The size and position of the appendicolith were ascertained. The study group was matched by age and gender to a control group. Both groups were contacted and interviewed regarding development of appendicitis. In total, 111 patients with appendicolith were successfully contacted and included in the study. Mean age was found to be 38 ± 15 y with 36 (32%) of the study population being females. Mean length of appendix was 66 ± 16 mm, and mean width was 5.8 ± 0.9 mm. Mean size of the appendicolith was 3.6 ± 1.1 mm (1.4-7.8 mm). Fifty-eight percent of appendicoliths was located at the proximal end or whole of appendix, 31% at mid area, and 11% at the distal end of appendix. All patients of the study and control groups were contacted, and at a mean follow-up of 4.0 ± 1.7 y, there was no occurrence of acute appendicitis in either group. Patients with incidentally discovered appendicolith on radiological imaging did not develop appendicitis. Hence, the risk of developing acute appendicitis for these patients does not seem higher than the general population. Copyright © 2017 Elsevier Inc. All rights reserved.

    Transradial access has become popular and preferred approach in coronary interventions due to high success rate, low risk of complications and patients' comfort. However various anatomical variations and anomalies may pose technical challenge. Arteria lusoria is an uncommon condition which is technically challenging and may warrant cross-over to alternate access. We report a middle aged male presenting with acute coronary syndrome in which arteria lusoria was incidentally detected during right transradial coronary intervention.

    2014-12-01

    Full Text Available Despite the fact that explicit teaching of vocabulary is often practised in English as a Second Language (ESL classrooms, it has been proven to be rather ineffective, largely because words are not taught in context. This has prompted the increasing use of incidental vocabulary learning approach, which emphasises on repeated readings as a source for vocabulary learning. By adopting this approach, this study aims to investigate students’ ability in learning vocabulary incidentally via verbal dramatization of written texts. In this case, readers’ theatre (RT is used as a way to allow learners to engage in active reading so as to promote vocabulary learning. A total of 160 diploma students participated in this case study and they were divided equally into two groups, namely classroom reading (CR and RT groups. A proficiency test was first conducted to determine their vocabulary levels. Based on the test results, a story was selected as the reading material in the two groups. The CR group read the story through a normal reading lesson in class while the RT group was required to verbally dramatize the text through readers’ theatre activity. Then, a post-test based on vocabulary levels was carried out and the results were compared. The findings revealed that incidental learning was more apparent in the RT group and their ability to learn words from the higher levels was noticeable through higher accuracy scores. Although not conclusive, this study has demonstrated the potential of using readers’ theatre as a form of incidental vocabulary learning activity in ESL settings.

    2017-07-01

    Musical knowledge is largely implicit. It is acquired without awareness of its complex rules, through interaction with a large number of samples during musical enculturation. Whereas several studies explored implicit learning of mostly abstract and less ecologically valid features of Western music, very little work has been done with respect to ecologically valid stimuli as well as non-Western music. The present study investigated implicit learning of modal melodic features in North Indian classical music in a realistic and ecologically valid way. It employed a cross-grammar design, using melodic materials from two modes (rāgas) that use the same scale. Findings indicated that Western participants unfamiliar with Indian music incidentally learned to identify distinctive features of each mode. Confidence ratings suggest that participants' performance was consistently correlated with confidence, indicating that they became aware of whether they were right in their responses; that is, they possessed explicit judgment knowledge. Altogether our findings show incidental learning in a realistic ecologically valid context during only a very short exposure, they provide evidence that incidental learning constitutes a powerful mechanism that plays a fundamental role in musical acquisition.

    Various studies were made on 400 renal (including 325 clinical cases) observed during whole-body bone scintigraphy using 99mTc-MDP. Asymmetrical renal images in bone scintigrams were obtained from 40% of the urologic patients and 7.5% of the nonurologic patients. Out of the asymmetrical images of the urologic patients, 50% provided nonvisualized kidneys and 35% showed unilateral renal high accumulation. It can be said from the above that renal images incidentally obtained during whole-body bone scintigraphy should not be overlooked

    2017-01-01

    The purpose of this study was to investigate the impact of lymphocytic thyroiditis on incidence of incidental thyroid cancers. We conducted a retrospective review of 713 consecutive patients who underwent thyroidectomies. Incidental thyroid cancer was defined as an unexpected cancer discovered on pathological examination outside the index nodule undergoing preoperative cytology. We excluded 65 cases because of preoperative diagnosis of thyroid cancer, and 68 because of nonincidental cancer within the index nodule. Among the remaining 580 cases, there were 43 cases (7.4%) of incidental thyroid cancers. Incidental thyroid cancers were significantly associated with moderate/severe lymphocytic thyroiditis (relative risk = 2.5; p = .03). Sixteen of 56 patients with moderate/severe lymphocytic thyroiditis had Graves' disease, none of whom had incidental thyroid cancer. The risk of incidental thyroid cancer associated with moderate/severe lymphocytic thyroiditis was significantly higher in non-Graves' than patients with Graves' disease (p = .05). The risk of incidental thyroid cancer is significantly increased in patients with moderate/severe lymphocytic thyroiditis. Moderate/severe lymphocytic thyroiditis associated with Graves' disease seems to have a lower risk of incidental thyroid cancer. © 2016 Wiley Periodicals, Inc.

  17. Approach to the management of incidental venous thromboembolic events in patients with cancer.

    O'Connell, Casey L; Liebman, Howard A

    2014-11-01

    Venous thromboembolism (VTE) is a frequent clinical complication of cancer and its treatment. Although much of the epidemiologic data regarding this complication have been based on symptomatic events, the use of multidetector row CT scanner technology has led to increased identification of VTE on scans ordered primarily for staging or restaging of malignancy. These incidentally discovered VTEs are variously referred to in the literature as incidental, asymptomatic, unexpected, or unsuspected VTE. A recent guidance paper by the Hemostasis and Malignancy Subcommittee of the International Society on Thrombosis and Haemostasis provided recommendations regarding this terminology (now termed incidental) and reporting of incidental VTE for clinical trials. A growing number of retrospective and case-controlled reports have described the prevalence, prognostic implications, and treatment options for these incidentally discovered VTE events, and have reported similar clinical outcomes for patients with incidental and symptomatic VTE. Because most reported patients with incidental VTE have been treated in a manner similar to those with symptomatic events, the present recommendations, except in rare circumstances, support the use of standard anticoagulation in the management of incidental deep vein thrombosis and pulmonary embolism.

  2. The incidental binding of color and shape is insensitive to the perceptual load

    Full Text Available Abstract The binding of information in visual short-term memory may occur incidentally when irrelevant information for the task at hand is stored together with relevant information. We investigated the process of the incidental conjunction of color and shape (Exp1 and its potential association with the selection of relevant information to the memory task (Exp2. The results in Exp1 show that color and shape are incidentally and asymmetrically conjugated: color interferes with the recognition of shape; however, shape does not interfere with the recognition of color. In Exp2, we investigated whether an increase in perceptual load would eliminate the processing of irrelevant information. The results of this experiment show that even with a high perceptual load, the incidental conjunction is not affected, and color remains to interfere with shape recognition, suggesting that the incidental conjunction is an automatic process.

    We report a case of primary colonic lymphoma incidentally diagnosed in a patient presenting a gallbladder attack making particular attention on the diagnostic findings at ultrasound (US) and total body computed tomography (CT) exams that allowed us to make the correct final diagnosis. A 85-year-old Caucasian male patient was referred to our department due to acute pain at the upper right quadrant, spreaded to the right shoulder blade. Patient had nausea and mild fever and Murphy's maneuver was positive. At physical examination a large bulky mass was found in the right flank. Patient underwent to US exam that detected a big stone in the lumen of the gallbladder and in correspondence of the palpable mass, an extended concentric thickening of the colic wall. CT scan was performed and confirmed a widespread and concentric thickening of the wall of the ascending colon and cecum. In addition, revealed signs of microperforation of the colic wall. Numerous large lymphadenopathies were found in the abdominal, pelvic and thoracic cavity and there was a condition of splenomegaly, with some ischemic outcomes in the context of the spleen. No metastasis in the parenchimatous organs were found. These imaging findings suggest us the diagnosis of lymphoma. Patient underwent to surgery, and right hemicolectomy and cholecystectomy was performed. Histological examination confirmed our diagnosis, revealing a diffuse large B-cell lymphoma. The patient underwent to Cyclophosphamide, Hydroxydaunorubicin, Oncovin, Prednisone chemotherapy showing only a partial regression of the lymphadenopathies, being in advanced stage at the time of diagnosis.

    Two methods were used to distinguish airborne engineered nanomaterials from other airborne particles in a facility that produces nano-structured lithium titanate metal oxide powder. The first method involved off-line analysis of filter samples collected with conventional respirable samplers at each of seven locations (six near production processes and one outdoors). Throughout most of the facility and outdoors, respirable mass concentrations were low (titanium determined with inductively coupled plasma atomic emission spectrometry). In contrast, in a single area with extensive material handling, mass concentrations were greatest (0.118 mg m(-3)) and contained up to 39% +/- 11% lithium titanium, indicating the presence of airborne nanomaterial. Analysis of the filter samples collected in this area by transmission electron microscope and scanning electron microscope revealed that the airborne nanomaterial was associated only with spherical aggregates (clusters of fused 10-80 nm nanoparticles) that were larger than 200 nm. This analysis also showed that nanoparticles in this area were the smallest particles of a larger distribution of submicrometer chain agglomerates likely from welding in an adjacent area of the facility. The second method used two, hand-held, direct-reading, battery-operated instruments to obtain a time series of very fine particle number (product is predominately composed of particles larger than several hundred nanometers. The methods presented here are applicable to any occupational or environmental setting in which one needs to distinguish incidental sources from engineered product.

    Bone scanning performed in the Nuclear Medicine Center (IPEN-INEN) to patients with neoplastic diagnosis between January 1995 and June 1996, permitted the incidental finding of increased uptake images in the knees of 28 patients associated to an asymptomatic arthropathy: osteoarthritis. The histories and bone scanning of this patients were reviewed obtaining their weight, occupation, symptomatology, neoplastic diagnosis and previous scan diagnosis. Patients under 66 years old, asymptomatic, were included, not presenting secondary focuses, without arthropathia antecedent and with a body mass index equal or above class I. The arthropathy was classified according to the localization of the compromised compartment of the knee. >From the body mass index assessment of every patient it was obtained: Class I=12, Class II=11, Class III=3 and Class IV=1. The predominant localization of the osteoarthritic lesions was the patellar zone. We discuss factors that may influence the absence of symptoms of this disease, the relation obesity-osteoarthritis and the usefulness of bone scanning in the diagnosis of this arthropathy in these patients.

    Full Text Available INTRODUCTION Castleman disease was for the first time described in 1956 as a mediastinal tumour mass. Etiology of this disease is still unknown. The disease can be solitary and multicentric or rarely of a mixed type. The former is often of hyaline vascular type, while the latter is of plasma cell type. CASE REPORT Castleman disease was diagnosed in a 26-year old male patient when a well defined shadow was incidentally detected in the middle lobe of the right lung. A year before, he was diagnosed with allergic rhinitis to Ambrosia. Two years after surgery the patient was feeling well, and was without any recurrence, however, allergic rhinitis still persisted. CONCLUSION Castleman disease can occur in any organ containing lymph tissues. Most frequently the disease is described as mediastinal, rarely as an intrapulmonary tumorous mass, and it is most frequently seen in younger persons. The solitary type of Castleman disease is surgical treatable with a prospect of good prognosis, while the multicentric and mixed types recur despite treatment with cortisone, irradiation and cytostatics. As the association between Castleman disease and allergic diseases has not been confirmed up-tonow, it could be concluded that this patient suffered from two separated diseases.

    Objectives To evaluate the validity and compare the performance of cancer antigen-125 (CA-125), human epididymis protein 4 (HE4), the risk of malignancy index (RMI), and the risk of ovarian malignancy algorithm (ROMA) in the diagnosis of ovarian cancer in patients with ovarian lesions discovered during their preoperative work-up investigations. Methods This prospective, cross-sectional study looked at patients who attended the gynecology department at the Royal Hospital, Muscat, from 1 March 2014 to 30 April 2015, for the evaluation of an ovarian lesion. The inclusion criteria included women who underwent surgical intervention and who had a preoperative pelvic ultrasound with laboratory investigation for CA-125 and HE4. The study validated the diagnostic performance of CA-125, RMI, HE4, and ROMA using histopathological diagnosis as the gold standard. Results The study population had a total of 213 cases of various types of benign (77%) and malignant (23%) ovarian tumors. CA-125 showed the highest sensitivity (79%) when looking at the total patient population. When divided by age, the sensitivity was 67% in premenopausal women. In postmenopausal women, CA-125 had lower sensitivity (89%) compared to RMI, HE4, and ROMA (93% each). A high specificity of 90% was found for HE4 in the total patient population, 93% in premenopausal women and 75% in postmenopausal women. CA-125 had the highest specificity (79%) in postmenopausal women. Both CA-125 and RMI were frequently elevated in benign gynecological conditions particularly in endometriosis when compared to HE4 and ROMA. We also studied modifications of the optimal cut-offs for the four parameters. Both CA-125 and RMI showed a significant increase in their specificity if the cut-off was increased to ≥ 60 U/mL for CA-125 and to ≥ 250 for RMI. For HE4, we noted an improvement in its specificity in postmenopausal women when its cut-off was increased to140 pmol/L. Conclusions HE4 and ROMA showed a very high specificity, but were less sensitive than CA-125 and RMI in premenopausal women. However, they were of comparable sensitivity in postmenopausal women and were valuable in distinguishing benign ovarian tumors or endometriosis from ovarian cancer. Modifying the cut-off values of the different markers resulted in a higher accuracy compared to the standard cut-offs, but at the expense of reduced sensitivity. PMID:27602187

  10. Cutaneous Adnexal Cylindroma of Breast: Epithelial Immunoreactivities for GATA-3, Mammaglobin, and E-Cadherin Do Not Equate to a Mammary Ductal Neoplasm

    Directory of Open Access Journals (Sweden)

    A. Halima

    2018-01-01

    Full Text Available Cylindromas are benign epithelial neoplasms derived from cutaneous eccrine adnexal structures. These tumors are most commonly encountered on the head, neck, and scalp of older women. In rare instances, solitary cylindromas may arise at other body sites. In the current case, a cylindroma of the skin of the breast was diagnosed by complete excision. Immunohistochemical studies confirmed the tumor cells to be immunoreactive with cytokeratin AE1/3, cytokeratin 5/6, cytokeratin 7, p63, and SOX10. The neoplastic cells were also noted to be immunoreactive with markers typically expected to be positive in ductal epithelium of the breast including GATA3, mammaglobin, and E-cadherin. The case emphasizes the importance of correlating clinical setting, imaging studies, patient history, and careful microscopic evaluation in arriving at an accurate diagnosis. This case also illustrates the point that not all “breast” tumors that are confirmed to be positive for GATA3, mammaglobin, and E-cadherin are derived from mammary ducts.

    The treatment of syringoma and trichoepithelioma has included punch and shave biopsy, excision, electrodessication, as well as continuous wave and superpulsed carbon dioxide laser ablation. More recently, high-energy pulsed CO2 lasers have been reported to be effective with standard available handpieces that deliver collimated beams. To report our experience using a focusing handpiece (1.0 mm spot at focus) with a high energy pulsed CO2 laser. Four patients with syringoma and two with multiple trichoepithelioma were treated with a high energy pulsed CO2 laser using a 1 mm spot size focusing handpiece. Pulse energies ranged from 125 to 250 mJ. All patients were followed 2 weeks after treatment and then for variable periods ranging from 8 to 18 months (mean=13.3 months). The 1 mm spot focusing handpiece permitted rapid tumor ablation with optimal matching of lesion size and laser spot diameter. Recurrence of tumor was associated with superficial ablation while complications such as hypopigmentation and atrophy were associated with deeper ablation. Facial adnexal tumors such as syringoma and trichoepithelioma can be successfully treated with the 1.0 mm handpiece in tandem with high energy pulsed CO2 lasers.

    The objective of the study is to determine the prevalence and significance of incidental findings in patients with a chief complaint of abdominal pain presenting to the emergency department (ED) who received abdomino-pelvic multidetector computed tomography. We conducted a retrospective review of data collected for 290 patients over a period of 5 months (April to September 2012) from 3 different university-affiliated EDs. Two board-certified radiologists reviewed the original images independently and recorded the incidental findings. These findings were classified as benign, indeterminate, and worrisome. Only those findings present in the original report were included in the study. If an indeterminate or worrisome incidental finding was identified, the patient's medical records were reviewed to determine if the incidental finding was previously known, whether recommendation was made for further evaluation, and whether this recommendation led to any change in management. We identified 283 incidental findings—144 benign (51%), 114 indeterminate (40%), and 25 worrisome (9%) findings. A statistically significant difference was observed in the percentage of patients who experienced a change in management among those who received recommendations as compared with those who did not, in both previously known (87% vs 22%, P=.001) and previously unknown (70% vs 2%, P=.001) indeterminate findings. Unlike benign incidental findings, indeterminate and worrisome findings frequently alter the course of management. Recommendation from radiologists appears to significantly contribute to the management of indeterminate incidental findings.

    No consensus yet exists on how to handle incidental findings (IFs) in human subjects research. Yet empirical studies document IFs in a wide range of research studies, where IFs are findings beyond the aims of the study that are of potential health or reproductive importance to the individual research participant. This paper reports recommendations of a two-year project group funded by NIH to study how to manage IFs in genetic and genomic research, as well as imaging research. We conclude that researchers have an obligation to address the possibility of discovering IFs in their protocol and communications with the IRB, and in their consent forms and communications with research participants. Researchers should establish a pathway for handling IFs and communicate that to the IRB and research participants. We recommend a pathway and categorize IFs into those that must be disclosed to research participants, those that may be disclosed, and those that should not be disclosed.

    When affective experiences are inconsistent with activated evaluative concepts, people experience what is called affective incoherence; when affective experiences are consistent with activated evaluative concepts, people experience affective coherence. The present research asked whether incidental feelings of affective coherence and incoherence would regulate persuasion. Experiences of affective coherence and incoherence were predicted and found to influence the processing of persuasive messages when evoked prior to receipt of such messages (Experiments 1 and 3), and to influence the confidence with which thoughts generated by persuasive messages were held when evoked after presentation of such messages (Experiments 2 and 3). These results extend research on affective coherence and incoherence by showing that they exert a broader impact on cognitive activity than originally assumed.

    Dynamic face cues can be very salient, as when observing sudden shifts of gaze to a new location, or a change of expression from happy to angry. These highly salient social cues influence judgments of another person during the course of an interaction. However, other dynamic cues, such as pupil dilation, are much more subtle, affecting judgments of another person even without awareness. We asked whether such subtle, incidentally perceived, dynamic cues could be encoded in to memory and retrieved at a later time. The current study demonstrates that in some circumstances changes in pupil size in another person are indeed encoded into memory and influence judgments of that individual at a later time. Furthermore, these judgments interact with the perceived trustworthiness of the individual and the nature of the social context. The effect is somewhat variable, however, possibly reflecting individual differences and the inherent ambiguity of pupil dilation/constriction. © 2016 The British Psychological Society.

    Appendicitis is the most common condition leading to an intraabdominal operation for a non obstetric problem in pregnancy and diagnosis of appendicitis is complicated by the physiologic and anatomic changes that occur during pregnancy. Although a surgical procedure carries the risk of fetal loss or preterm delivery, delay in diagnosis also increases the risk of complications in both mother and fetus. In this report we present our experience and analyze clinical characteristic and the pregnancy outcomes of appendicitis diagnosed incidentally during cesarean in the third trimester. The study population consisted of 23 pregnant women who were diagnosed incidentally with appendicitis during cesarean at Erzincan University Hospital between 2015 and 2016. Appendectomy was performed on 23 patients during a caesarean section performed for any reason. The mean dia-meter of appendix was 7.82 ± 1.85 mm. The mean operation time was 67.39 ± 18.94 SD and antibiotic therapy was given to all patients. Postoperative complications were noted in 4 (17.4%) patients. Wound infection was seen in 4 (17.4%) patients, the other 19 patients revealed no postoperative complications. The mean of APGAR score of newborns in the postoperative period was 8.26 ± 0.86 SD and no complications were observed in both mothers and newborns. Histopathology of the specimen confirmed acute appendicitis in 23 (100%) cases. Acute appendicitis is a challenging diagnosis in the pregnant patient; however, early surgical intervention should be performed with any suspicion. The type of surgery depends on the surgeon's preference and experience.

    The wider use of MRI for imaging of the head in both research and clinical practice has led to an increasing number of intracranial incidental findings. Most of these findings have no immediate medical consequences. Nevertheless, knowledge of common intracranial incidental findings and their clinical relevance is necessary to adequately discuss the findings with the patient. Based on the author's experiences from a large population-based study, the most common incidental MR findings in the brain will be presented, discussing their clinical relevance and giving recommendations for management according to the current literature and guidelines.

    To compare clinical and humoral parameters before and after surgery in patients with incidental adrenocortical adenomas. Six patients with subclinical Cushing's syndrome and nine with non-functioning adenomas were investigated before and 12 Months after removal of the mass. Anthropometric (body weight, body mass index and waist to hip ratio), haemodynamic (blood pressure and heart rate), metabolic (lipids and oral glucose tolerance test (OGTT)), hormonal (cortisol, plasma renin activity, aldosterone, androgens and catecholamines) and bone metabolism (hydroxyproline, parathyroid hormone, osteocalcin and ostase) parameters were evaluated. In the whole group, a significant decrease in body weight (69.7+/-3.5 vs 70.8+/-3.5 kg, P<0.03), in systolic (135.3+/-5.1 vs 145.6+/-4.9 mmHg, P<0.009) and diastolic (83.7+/-1.9 vs 91.0+/-3.5 mmHg, P<0.03) blood pressure and in glucose levels in response to OGTT (106.4+/-9.6 vs 127.5+/-6.5 mg/dl, P<0.05) was observed after surgery. All other parameters examined did not change significantly. This trend was also found in both groups separately. Analytical data showed a high frequency of overweight/obesity (66.6%), hypertension (66.6%) and impaired glucose profile (26.6%) in our patients, with a greater prevalence of these cardiovascular risk factors in the subclinical Cushing's syndrome group. After surgery, values normalized or improved in eight out of ten hypertensive patients and in three out of four patients with impaired glucose profile. Solid adrenocortical incidentalomas are associated with some cardiovascular risk factors which may be corrected after removal of the mass. Therefore, surgery may be an appropriate choice in patients with subclinical Cushing's syndrome but also in those with solid non-functioning adenomas and coexistent cardiovascular risk factors.

    Full Text Available Hepatocellular carcinoma (HCC usually occurs in patients with underlying risk factors such as liver cirrhosis and chronic hepatitis B. Although patients with Crohn’s disease (CD are at an increased risk to develop malignancies such as colon cancer, the incidence of HCC in this population is extremely rare. We report a case of 62-year-old male with long history of CD treated with azathioprine (AZA and aminosalicylic acid (ASA who was incidentally diagnosed with HCC, for which left hepatectomy was done. Four years later during routine follow-up, patient had another hepatic lesion and underwent resection of the mass. The mechanism of occurrence of HCC in patient with CD is still controversial and may include immune mediated changes and medication related complications. AZA was reported in all case reports of CD that developed HCC. Through this report we hope to explore the complex pathophysiological mechanisms contributing to the development of HCC in the Crohn’s disease patient population.

    Thallium-201 (Tl-201) is widely used for myocardial perfusion imaging, but is also reported to have potential tumor-seeking properties. Tl-201 uptake has been described in various malignant diseases, including thymic tumors. Thymomas are the most frequent tumors of the anterior mediastinum, and chest pain is one of the major presentation symptoms. Sometimes, a thymoma may be overlooked on chest plain film. We report on a case of a 63-year-old man who had a history of hypertension and suffered from intermittent chest pain for several weeks. He underwent a Tl-201 stress test to evaluate the presence of coronary artery disease, and during the test, abnormal uptake over focal extracardiac activity in the left upper mediastinum was incidentally revealed. Furthermore, chest computed tomography identified a 6-cm left anterior mediastinal mass. Mediastinal tumor resection was carried out, and the pathological examination demonstrated an invasive epithelial-type thymoma, which had invaded the left innominate vein. Subsequently, the patient received postoperative radiotherapy and thenceforth responded well to treatment. A Tl-201 scan has the potential to play a part in tumor detection and clinical assessment of therapeutic effects.

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

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

    2013-01-01

    First language acquisition requires relatively little effort compared to foreign language acquisition and happens more naturally through informal learning. Informal exposure can also benefit foreign language learning, although evidence for this has been limited to speech perception and production. An important question is whether informal exposure to spoken foreign language also leads to vocabulary learning through the creation of form-meaning links. Here we tested the impact of exposure to foreign language words presented with pictures in an incidental learning phase on subsequent explicit foreign language learning. In the explicit learning phase, we asked adults to learn translation equivalents of foreign language words, some of which had appeared in the incidental learning phase. Results revealed rapid learning of the foreign language words in the incidental learning phase showing that informal exposure to multi-modal foreign language leads to foreign language vocabulary acquisition. The creation of form-meaning links during the incidental learning phase is discussed.

    Directory of Open Access Journals (Sweden)

    Ethan Frank

    2018-03-01

    Full Text Available Epidermal inclusion cysts are common lesions that rarely develop into squamous cell carcinoma (SCC. Neoplastic change in these cysts can be associated with prominent symptoms such as pain, rapid growth, or ulceration. This study describes the case of a 64-year-old woman with a 4-year history of a largely asymptomatic neck mass, which after routine excision was found to be an epidermal inclusion cyst harboring well-differentiated SCC. The diagnosis was made incidentally after routine cyst bisection and hematoxylin and eosin staining. Given the potential for variable presentation and low cost of hematoxylin and eosin analysis, we recommend a low threshold for a comprehensive pathological search for malignancy in excised cysts when appropriate.

  11. Factors influencing incidental representation of previously unknown conservation features in marine protected areas.

    2016-02-01

    Spatially explicit information on species distributions for conservation planning is invariably incomplete; therefore, the use of surrogates is required to represent broad-scale patterns of biodiversity. Despite significant interest in the effectiveness of surrogates for predicting spatial distributions of biodiversity, few researchers have explored questions involving the ability of surrogates to incidentally represent unknown features of conservation interest. We used the Great Barrier Reef marine reserve network to examine factors affecting incidental representation of conservation features that were unknown at the time the reserve network was established. We used spatially explicit information on the distribution of 39 seabed habitats and biological assemblages and the conservation planning software Marxan to examine how incidental representation was affected by the spatial characteristics of the features; the conservation objectives (the minimum proportion of each feature included in no-take areas); the spatial configuration of no-take areas; and the opportunity cost of conservation. Cost was closely and inversely correlated to incidental representation. However, incidental representation was achieved, even in a region with only coarse-scale environmental data, by adopting a precautionary approach that explicitly considered the potential for unknown features. Our results indicate that incidental representation is enhanced by partitioning selection units along biophysical gradients to account for unknown within-feature variability and ensuring that no-take areas are well distributed throughout the region; by setting high conservation objectives that (in this case >33%) maximize the chances of capturing unknown features incidentally; and by carefully considering the designation of cost to planning units when using decision-support tools for reserve design. The lessons learned from incidental representation in the Great Barrier Reef have implications for

  12. Relative Preference and Localized Food Affect Predator Space Use and Consumption of Incidental Prey.

    Directory of Open Access Journals (Sweden)

    Tyler E Schartel

    Full Text Available Abundant, localized foods can concentrate predators and their foraging efforts, thus altering both the spatial distribution of predation risk and predator preferences for prey that are encountered incidentally. However, few investigations have quantified the spatial scale over which localized foods affect predator foraging behavior and consumption of incidental prey. In spring 2010, we experimentally tested how point-source foods altered how generalist predators (white-footed mice, Peromyscus leucopus utilized space and depredated two incidental prey items: almonds (Prunus dulcis; highly profitable and maple seeds (Acer saccharum; less profitable. We estimated mouse population densities with trapping webs, quantified mouse consumption rates of these incidental prey items, and measured local mouse activity with track plates. We predicted that 1 mouse activity would be elevated near full feeders, but depressed at intermediate distances from the feeder, 2 consumption of both incidental prey would be high near feeders providing less-preferred food and, 3 consumption of incidental prey would be contingent on predator preference for prey relative to feeders providing more-preferred food. Mouse densities increased significantly from pre- to post-experiment. Mean mouse activity was unexpectedly greatest in control treatments, particularly <15 m from the control (empty feeder. Feeders with highly preferred food (sunflower seeds created localized refuges for incidental prey at intermediate distances (15 to 25m from the feeder. Feeders with less-preferred food (corn generated localized high risk for highly preferred almonds <10 m of the feeder. Our findings highlight the contingent but predictable effects of locally abundant food on risk experienced by incidental prey, which can be positive or negative depending on both spatial proximity and relative preference.

    This study used eye tracking to investigate the allocation of attention to multimodal stimuli during an incidental learning situation, as well as its impact on subsequent explicit learning. Participants were exposed to foreign language (FL) auditory words on their own, in conjunction with written native language (NL) translations, or with both written NL translations and pictures. Incidental acquisition of FL words was assessed the following day through an explicit learning task where participants learned to recognize translation equivalents, as well as one week later through recall and translation recognition tests. Results showed higher accuracy scores in the explicit learning task for FL words presented with meaning during incidental learning, whether written meaning or both written meaning and picture, than for FL words presented auditorily only. However, participants recalled significantly more FL words after a week delay if they had been presented with a picture during incidental learning. In addition, the time spent looking at the pictures during incidental learning significantly predicted recognition and recall scores one week later. Overall, results demonstrated the impact of exposure to multimodal stimuli on subsequent explicit learning, as well as the important role that pictorial information can play in incidental vocabulary acquisition.

    Full Text Available Background: Imaging abnormalities in the paranasal sinuses are regularly noted as incidental findings on MRI, however, little is known about their prevalence in the Iranian population. The purpose of this study was to classify these findings in the paranasal sinuses as seen on MRI and to investigate the prevalence, according to site and type of paranasal abnormality. Methods: In this cross-sectional study, the T2-weighted axial MRI of 256 patients with diseases unrelated to their paranasal sinuses were reviewed between May 2002 and June 2003. The findings were categorized according to the anatomic location and the imaging characteristics of the abnormality. The abnormalities recorded included total sinus opacification, mucoperiosteal thickening >5mm, air fluid levels and retention cysts or polyps. Unilateral or bilateral involvement and septal deviation were also noted. A sinus was considered normal if it was fully aerated and no soft-tissue density was apparent within the cavity. Results: Among our cases, 111 (43.5% were male and 145 (56.5% were female. Of these patients, abnormalities in one or more of the sinus groups were found in 110 subjects (42.9%, 55.5% of which were male and 44.5% were female (P=0.001. Maxillary sinus abnormalities were observed in 66.4% of the patients, while ethmoid sinus abnormalities were found in 63.6%. Of the ethmoid abnormalities, 21% were found in the anterior section, 9% in the middle ethmoid, and 8% in the posterior ethmoid. The most common abnormality found was mucosal thickening. Among our cases, 23.4% had septal deviation, which was significantly higher among those with sinusitis (29% versus 19.1%; P<0.01. Of those patients with sinus involvement, 16% were involved in the sphenoid sinus and 5% in the frontal sinus. The results obtained from the patients with sinus abnormality revealed that 85% suffered from cough, nasal obstruction, runny nose, facial pain and post nasal discharge and 24% had been diagnosed

    The aim of the present study was to determine the prevalence and reporting rate of incidental findings (IF) in adult outpatients undergoing lumbar magnetic resonance imaging (MRI). Re-evaluation of a total of 1278 lumbar MRI images (collected from patients with a mean age of 50.5 years, range 16-91 years) captured between August 2010-August 2011 was done by a neuroradiologist and a musculoskeletal radiologist. IFs were classified according to organ or system (liver, gallbladder, kidney, bladder, uterus, ovary, lymph node, intestine and aorta). The rate of reporting of a range of IF was examined. The outcome of each patient's treatment was evaluated based on review of hospital records and by telephone interviews. A total of 253 IFs were found in 241 patients (18.8% of 1278). Among these, clinically significant IFs (n = 34) included: 2 renal masses (0.15%), 2 aortic aneurysms (0.15%), 2 cases of hydronephrosis (0.15%), 11 adrenal masses (0.86%), 7 lymphadenopathies (0.55%), 6 cases of endometrial or cervical thickening (0.47%), 1 liver hemangioma (0.08%), 1 pelvic fluid (0.08%) and 2 ovarian dermoid cysts (0.15%). Overall, 28% (71/253) of IFs were included in the clinical reports, while clinically significant findings were reported in 41% (14/34) of cases. Extraspinal IFs are commonly detected during a routine lumbar MRI, and many of these findings are not clinically significant. However, IFs including clinically important findings are occasionally omitted from formal radiological reports.

    Purpose: To evaluate the accuracy in distinguishing adrenal adenomas from nonadenomas by means of quadriphasic CT exam, including unenhanced (UE), arterial enhanced (AE), portal enhanced (PE) and 5-min delayed enhanced (DE) CT scans. Methods: This retrospective study had institutional review board approval; the need for informed consent was waived. From September 2007 to September 2009, 104 adrenal masses were evaluated in 87 patients (49 M, 38 F, mean age 58.4 years) undergoing UE, AE (35-s delay), PE (80-s delay) and DE (5-min delay) CT scans. The mean adrenal attenuation during all imaging phases was measured by two readers. The accuracy values of absolute unenhanced attenuation (UE), absolute wash-out (AWO), relative percentage wash-out (RPWO) and percentage enhancement wash-out (PEW) were assessed by using receiver operator curves (ROC) analysis. The overall accuracy of the quadriphasic protocol and other triphasic protocols were evaluated. A value of p ≤ 0.05 was considered significant. Results: The accuracy in characterizing adrenal lesions was 86.5% (90/104) for UE attenuation (≤10 HU threshold), 90.1% (82/91) for RPWO (≥30% threshold), 85.7% (78/91) for AWO (≥12 HU threshold) and 83.5% (76/91) for PEW (≥30% threshold), respectively. Quadriphasic CT (accuracy 97.1%, 101/104) performed better than triphasic CT including only AE scan (efficiency 90.0%, 94/104; p = 0.011) and triphasic CT including only PE scan (efficiency 96.1%, 100/104; p = 0.025). Conclusion: Quadriphasic CT protocol including 5-min DE scan may be used to characterize incidentally detected adrenal masses. RPWO represented the best wash-out parameter for characterizing adrenal lesions.

    To report the clinical features in a series of patients with perineural spread of squamous cell carcinoma involving periorbital nerves that presented with clinical and/or imaging evidence of pseudo-cystic transformation along the involved nerves. A noncomparative, retrospective chart review of the clinical and imaging findings of patients attending a regional orbital surgery department between 1998 and 2005, presenting with a pseudo-cystic orbital mass on clinical examination and/or imaging, which proved to be due to perineural squamous cell carcinoma on histopathology. The study included 8 male patients with a mean age at referral of 66 +/- 11 years. All cases had associated cutaneous squamous cell carcinoma involving the face or scalp, and, in 4 cases, the primary tumor could be identified in the vicinity of the affected orbit. The duration of the symptoms varied from 5 weeks to 9 years (24 +/- 36 months). Altered sensation, including formication and hypo-esthesia in the V1 and V2 trigeminal division, motor nerve palsies, and ptosis in conjunction with a palpable periorbital mass, were the most common presentations. The cystic tumor deposits were assessed histologically with both hematoxylin and eosin and immunoperoxidase stains (S100 protein for neural structures identification and MNF116 as a keratin marker). This demonstrated malignant squamous epithelium both within and around the wall of the tumor deposit and, in continuity, within the nerve running through the lesion. Some nerves showed substantial areas of fibrosis, representing obliteration of the nerve structure caused by involvement by tumor. Treatment modalities included surgical debulking, exenteration, radiotherapy, and combined chemo-radiotherapy. Mean follow-up was 29 +/- 23 months. Eight patients (87.5%) remain alive, and five of them show no evidence of disease. One patient died after progression of the malignancy.

    Full Text Available Abstract Background Investigation of pulmonary pathology with computed tomography also allows visualisation of the heart and major vessels. We sought to explore whether clinically relevant cardiac pathology could be identified on computed tomography pulmonary angiograms (CTPA requested for the exclusion of pulmonary embolism (PE. 100 consecutive CT contrast-enhanced pulmonary angiograms carried out for exclusion of PE at a single centre were assessed retrospectively by two cardiologists. Findings Evidence of PE was reported in 5% of scans. Incidental cardiac findings included: aortic wall calcification (54%, coronary calcification (46%, cardiomegaly (41%, atrial dilatation (18%, mitral annulus calcification (15%, right ventricular dilatation (11%, aortic dilatation (8% and right ventricular thrombus (1%. Apart from 3 (3% reports describing cardiomegaly, no other cardiac findings were described in radiologists' reports. Other reported pulmonary abnormalities included: lung nodules (14%, lobar collapse/consolidation (8%, pleural effusion (2%, lobar collapse/consolidation (8%, emphysema (6% and pleural calcification (4%. Conclusions CTPAs requested for the exclusion of PE have a high yield of cardiac abnormalities. Although these abnormalities may not have implications for acute clinical management, they may, nevertheless, be important in long-term care.

    Opportunistic observations of behavioral responses by delphinids to incidental mid-frequency active (MFA) sonar were recorded in the Southern California Bight from 2004 through 2008 using visual focal follows, static hydrophones, and autonomous recorders. Sound pressure levels were calculated between 2 and 8 kHz. Surface behavioral responses were observed in 26 groups from at least three species of 46 groups out of five species encountered during MFA sonar incidents. Responses included changes in behavioral state or direction of travel, changes in vocalization rates and call intensity, or a lack of vocalizations while MFA sonar occurred. However, 46% of focal groups not exposed to sonar also changed their behavior, and 43% of focal groups exposed to sonar did not change their behavior. Mean peak sound pressure levels when a behavioral response occurred were around 122 dB re: 1 μPa. Acoustic localizations of dolphin groups exhibiting a response gave insight into nighttime movement patterns and provided evidence that impacts of sonar may be mediated by behavioral state. The lack of response in some cases may indicate a tolerance of or habituation to MFA sonar by local populations; however, the responses that occur at lower received levels may point to some sensitization as well.

    Full Text Available Abstract Introduction Gestational choriocarcinoma occurs in 1 in 40,000 pregnancies. Of all forms of gestational choriocarcinoma, placental choriocarcinoma is the most rare. Maternal choriocarcinoma is usually diagnosed in symptomatic patients with metastases. The incidental finding of a choriocarcinoma confined to the placenta with no evidence of dissemination to the mother, or infant is the least common scenario. Case presentation The patient is an 18 year-old Gravida 1 Para 1 African American female who delivered a viable 3641 g female infant at 39 weeks gestation. Her pregnancy course was complicated by gestational hypertension during the third trimester. Her placenta revealed intraplacental choriocarcinoma. She was then followed closely by the Gynecologic Oncology service with a weekly serum beta human chorionic gonadotropin value. Beta human chorionic gonadotropin values dropped from 3070 mIU/ml to less than 2 mIU/ml two months post partum. No chemotherapy was initiated. Metastasis was ruled out by chest x-ray and whole body computed tomography scan. To date, both mother and baby are well. Conclusion Due to the potential fatal outcome of placental choriocarcinoma, careful evaluation of both mother and infant after the diagnosis is made is important. The incidence of placental choriocarcinoma may actually be higher than expected since it is not routine practice to send placentas for pathological evaluation after a normal spontaneous delivery. The obstetrician, pathologist, and pediatrician should have an increased awareness of placental choriocarcinoma and its manifestations.

    Full Text Available Ovarian torsion is a rare gynecological emergency. ovarian torsion is often seen in reproductive ages and salphingooopherectomy is performed for the treatment. However, surgically excision of one of the ovaries early in life causes severe damage to the future fertility. Many case series that were published recently, has been shown low complication rate of ovarian sparing surgery at ovarian torsion and have been preserved from the organ loss. In this study we presented 3 cases at young ages with giant torsioned adnexal masses managed by ovarian sparing surgery at laparotomy and revised the literature in the light of these cases.

    Patellofemoral chondral lesions are frequently identified incidentally during the arthroscopic treatment of other knee pathologies. A role has been described for arthroscopic debridement when symptoms are known to originate from pathology of the patellofemoral joint. However, it remains unclear how to manage lesions which are found incidentally whilst tackling other pathologies. The purpose of this study was to establish the strength of association between anterior knee pain and patellofemoral lesions identified incidentally in a typical arthroscopic population. A consecutive series of patients undergoing arthroscopy for a range of standard indications formed the basis of this cross section study. We excluded those with patellofemoral conditions in order to identify patellofemoral lesions which were solely incidental. Pre-operative assessments were performed on 64 patients, where anterior knee pain was sought by three methods: an annotated photographic knee pain map (PKPM), patient indication with one finger and by palpated tenderness. A single blinded surgeon, performed standard arthroscopies and recorded patellofemoral lesions. Statistical correlations were performed to identify the association magnitude. Associations were identified between incidental patellofemoral lesions and tenderness palpated on the medial patella (P = 0.007, χ(2) = 0.32) and the quadriceps tendon (P = 0.029, χ(2) = 0.26), but these associations were at best fair, which could be interpreted as clinically insignificant. Incidental patellofemoral lesions are not necessarily associated with anterior knee pain, we suggest that they could be left alone. This recommendation is only applicable to patellofemoral lesions which are found incidentally whilst addressing other pathology. Copyright © 2013 Elsevier B.V. All rights reserved.

The widespread use of the recently introduced multi-detector CT scanners has resulted in an increasing number of incidentally diagnosed pulmonary embolism (PE in asymptomatic cancer patients. The significance and clinical outcome of such incidental PE is described.Methods: Both radiology department and hospital databases were searched for all cancer patients with a diagnosis of incidental PE. CT scans were performed using a 64-slice scanner with a 5.0 mm slice thickness.Results: During the study period, 34 patients with incidental PE were identified. The mean age (±SD was 57.7 (±12.4 years. All patients had active cancer, gastric, lung, colorectal, and lymphomas being the most frequent. Most patients had advanced-stage disease at the time of PE diagnosis; 26 (77% patients had stage IV, whereas only 3 patients had stages I or II disease. Twenty-seven (79% patients had their PE while undergoing active treatment with chemotherapy (68% or radiotherapy (12%; none, however, were on hormonal therapy. Most (74% patients had their PE diagnosed without history of recent hospital admission. Except for 5 (15%, all other patients were anticoagulated. With follow-up, 2 patients developed recurrent PE, 2 others had clinical and echocardiographic evidence of pulmonary hypertension, and 9 (26% died suddenly within 30 days of the diagnosis of incidental PE; 2 of these where among the 5 patients who were not anticoagulated.Conclusion: Incidental PE in cancer patients is increasingly encountered. Similar to symptomatic PE, many were diagnosed in patients with advanced stage disease and while undergoing active anti-cancer therapy.

    Incidental parotid lesions on F-18 FDG-PET can mimic distant metastasis of underlying malignancy. The prevalence and the clinico-pathologic findings of PET positive parotid lesions have not been known. We investigated how often incidental parotid lesions are found on clinical FDG-PET studies and what the clinico-pathologic characteristics of those parotid lesions are in the present study. We retrospectively reviewed 3, 344 cases of FDG-PET which had been obtained in our hospital from May 2003 to Dec 2006. The indications of FDG-PET were: evaluation of known/suspected cancer (n=3, 212) or screening of cancer in healthy subjects (n=132). Incidental parotid lesion on FDG-PET was defined as an un-expected FDG uptake in one of parotid glands which was not primary target lesion of current FDG-PET. FDG uptake was represented by maximum standardized uptake value (maxSUV). Final diagnosis was made by pathologic analysis or clinical follow-up assessment. Fifteen (0.45% = 15/3, 344) incidental parotid lesions were found and they were all benign lesions. The maxSUV ranged from 1.7 to 8.6 (means.d.=3.71.9). Final diagnoses of the incidental parotid lesions were; Warthin's tumor (n=2), pleomorphic adenoma (n=1), other un-specified benign lesion (n=1), and benign lesions under bases of imaging studies (n=3) and of clinical follow-up (n=8). All of incidentally found parotid lesions in clinical FDG-PET studies were confirmed as benign lesions with prevalence of 0.45%. Close follow up using PET or CT might be a reasonable approach for determining the nature of incidentally found parotid lesions

    Full Text Available Focus on form instruction is a kind of instruction that draws students, attention to linguistic elements as they arise incidentally in meaning based instruction.  There are different types of focus on form instruction. The present study was designed to investigate the effect of incidental focus on form on grammatical accuracy among Iranian L2 learners. Eighty learners from Sahand language Institute in Miandoab after taking grammatical judgment test which was administered to homogenize them, were placed in two control and experimental groups. Learners in experimental group received feedback through recasting during retelling the reading passage according to principles of Jigsaw task. But learners in control group did not receive any feedback. After treatment, which lasted for eight sessions, post-test was given to both control and experimental groups to observe the difference resulted from the treatment. To be sure about the significance of the difference between post-test means of both groups, a t-test was used. The results at the end supported the hypotheses of the study and positive effect of incidental focus on form on grammatical accuracy of L2 learners. After that, for the purpose of analyzing the effect of incidental focus on form on accuracy of pronouns, tenses, articles and propositions separately, other tests (pronoun, article, tense, proposition tests was given to the learners in both control and experimental groups. The data collected was computed through t-test which revealed that the effect of incidental focus on form on grammatical accuracy of articles is greater than pronouns and tenses but incidental focus on form didn’t have any effect on accuracy of propositions. Pedagogical implications have been discussed. Keywords:  Focus on form, Incidental focus on form, recast, task, Accuracy

    The appropriate communication and management of incidental findings on emergency department (ED) radiology studies is an important component of patient safety. Guidelines have been issued by the ACR and other medical associations that best define incidental findings across various modalities and imaging studies. However, there are few examples of health care facilities designing ways to manage incidental findings. Our institution aimed to improve communication and follow-up of incidental radiology findings in ED patients through the collaborative development and implementation of system-level process changes including a standardized loop-closure method. We assembled a multidisciplinary team to address the nature of these incidental findings and designed new workflows and operational pathways for both radiology and ED staff to properly communicate incidental findings. Our results are based on all incidental findings received and acknowledged between November 1, 2016, and May 30, 2017. The total number of incidental findings discovered was 1,409. Our systematic compliance fluctuated between 45% and 95% initially after implementation. However, after overcoming various challenges through optimization, our system reached a compliance rate of 93% to 95%. Through the implementation of our new, standardized communication system, a high degree of compliance with loop closure for ED incidental radiology findings was achieved at our institution.

    Incidental asymptomatic aneurysms were found in 9 of 52 patients with intracranial aneurysms from February, 1978 to March, 1980. They had only mild initial symptoms, namely, headache, dysarthria, aphasis, light hemiparesis and others. No patients had severe neurological deficits. In eight of 9 patients with asymptomatic aneurysm, except one case of hypertensive intracerebral hematoma, 9 aneurysms (8 patients) were directly detected by high resolution CT (GE CT/T 8800) and confirmed by angiography. Location of these aneurysms as follows: three at the middle cerebral artery trifurcation, two at the internal carotisposterior communicans junction, one at anterior communication artery, one at the basilar top, one at the basilaris artery-superior cerebelli artery junction and one at the posterior cerebral artery. The smallest aneurysm detected by CT as 5 x 4 x 4 mm in size on angiography. The aneurysm may be suggested by small round or oval defect in the Sylvian fissure or suprasellar cistern, defect of the edge of the so called ''pentagon'' in the plain CT and then if its density is highly and homogeneously increased after contrast-enhanced (CE) scan. As the circle of Willis and other major cerebral arteries can often be demonstrated on CE.CT images, the aneurysm is frequently seen on these cerebral arteries. Limiting factors to direct CT detection of intracranial aneurysms are seemed to be size and location of aneurysm, anatomic location of circle of Willis and motion of patients etc. It may be considered, in our experiences, that the CT is useful in diagnosis of asymptomatic aneurysm and the higher direct CT detection rate to aneurysms, small or medium sized as well as giant aneurysms, will be obtained by devising scanning method, namely, multiprojection scans, multiple overlapping method and improvement of enhanced method.

    2011-01-01

    Full Text Available Abstract Introduction Pelvic actinomycosis constitutes 3% of all human actinomycosis infections. It is usually insidious, and is often mistaken for other conditions such as diverticulitis, abscesses, inflammatory bowel disease and malignant tumors, presenting a diagnostic challenge pre-operatively; it is identified post-operatively in most cases. Here we present a case that presented as pelvic malignancy and was diagnosed as pelvic actinomycosis post-operatively. Case presentation A 48-year-old Caucasian Turkish woman presented to our clinic with a three-month history of abdominal pain, weight loss and difficulty in defecation. She had used an intra-uterine device for 16 years, however it had recently been removed. The rectosigmoidoscopy revealed narrowing of the lumen at 12 cm due to a mass lesion either in the wall or due to an extrinsic lesion that prevented the passage of the endoscope. On examination, there was no gynecological pathology. Magnetic resonance imaging showed a mass, measuring 5.5 × 4 cm attached to the rectum posterior to the uterus. The ureter on that side was dilated. Surgically there was a pelvic mass adhered to the rectum and uterine adnexes, measuring 10 × 12 cm. It originated from uterine adnexes, particularly ones from the left side and formed a conglomerated mass with the uterus and nearby organs; the left ureter was also dilated due to the pelvic mass. Because of concomitant tubal abscess formation and difficulty in dissection planes, total abdominal hysterectomy and bilateral salphingo-oophorectomy was performed (our patient was 48 years old and had completed her childbearing period. The cytology revealed inflammatory cells with aggregates of Actinomyces. Penicillin therapy was given for six months without any complication. Conclusions Pelvic actinomycosis should always be considered in patients with a pelvic mass especially in ones using intra-uterine devices, and who have a history of appendectomy, tonsillectomy

  15. The Role of Repeated Exposure to Multimodal Input in Incidental Acquisition of Foreign Language Vocabulary.

    Prior research has reported incidental vocabulary acquisition with complete beginners in a foreign language (FL), within 8 exposures to auditory and written FL word forms presented with a picture depicting their meaning. However, important questions remain about whether acquisition occurs with fewer exposures to FL words in a multimodal situation and whether there is a repeated exposure effect. Here we report a study where the number of exposures to FL words in an incidental learning phase varied between 2, 4, 6, and 8 exposures. Following the incidental learning phase, participants completed an explicit learning task where they learned to recognize written translation equivalents of auditory FL word forms, half of which had occurred in the incidental learning phase. The results showed that participants performed better on the words they had previously been exposed to, and that this incidental learning effect occurred from as little as 2 exposures to the multimodal stimuli. In addition, repeated exposure to the stimuli was found to have a larger impact on learning during the first few exposures and decrease thereafter, suggesting that the effects of repeated exposure on vocabulary acquisition are not necessarily constant.

Theta (3-8 Hz and alpha (10-16 Hz neuronal oscillations were analyzed to compare encoding processes during an intentional and an incidental encoding task. In all three age groups, both encoding conditions were associated with an increase in event-related theta activity. Encoding-related alpha suppression increased with age. Memory performance was higher in the intentional compared to the incidental task in all age groups. Furthermore, intentional learning was associated with an improved encoding of perceptual features, which were relevant for the retrieval phase. Theta activity increased from incidental to intentional encoding. Specifically, frontal theta increased in all age groups, while parietal theta increased only in adults and older children. In younger children, parietal theta was similarly high in both encoding phases. While alpha suppression may reflect semantic processes during encoding, increased theta activity during intentional encoding may indicate perceptual binding processes, in accordance with the demands of the encoding task. Higher encoding-related alpha suppression in the older age groups, together with age differences in parietal theta activity during incidental learning in young children, is in line with recent theoretical accounts, emphasizing the role of perceptual processes in mnemonic processing in young children, whereas semantic encoding processes continue to mature throughout middle childhood.

    Incidental cardiovascular findings are a frequent phenomenon in computed tomography (CT) examinations. As the result of a dedicated PubMed search this article gives a systemic overview of the current literature on the most important incidental cardiovascular findings, their prevalence and clinical relevance. The majority of incidental cardiovascular findings are of only low clinical relevance; however, highly relevant incidental findings, such as aortic aneurysms, thromboses and thromboembolic events can also occasionally be found, especially in oncology patients. The scans from every CT examination should also be investigated for incidental findings as they can be of decisive importance for the further clinical management of patients, depending on their clinical relevance. (orig.) [German] Inzidentelle kardiovaskulaere Befunde sind ein haeufiges Phaenomen bei CT-Untersuchungen. Mit dieser Arbeit soll nach gezielter PubMed-Recherche ein systematischer Literaturueberblick ueber die wichtigsten kardiovaskulaeren Zufallsbefunde sowie deren Haeufigkeit und klinische Relevanz gegeben werden. Die Mehrzahl der inzidentellen kardiovaskulaeren Befunde sind klinisch nur von untergeordneter Bedeutung, allerdings werden immer wieder auch hochgradig relevante Zufallsbefunde wie beispielsweise Aortenaneurysmata oder - gerade bei onkologischen Patienten - Thrombosen und thrombembolische Ereignisse detektiert. Jede CT-Untersuchung sollte gezielt nach inzidentellen Befunden durchsucht werden, da diese je nach klinischer Relevanz von entscheidender Bedeutung fuer das weitere klinische Management des Patienten sein koennen.

    To test the hypothesis that there is no difference in trapeziometacarpal (TMC) joint arthrosis-related symptoms and disability between patients seeking treatment for symptoms of TMC arthrosis and those with incidental TMC joint arthrosis. We compared 64 patients presenting for care of TMC joint arthrosis with 64 with incidental TMC joint arthrosis. For both groups, the diagnosis was based on crepitation on examination. Bivariate and multivariate analyses assessed factors associated with symptoms and disability related to TMC joint arthrosis. In bivariate analysis, patients presenting for care of TMC joint arthrosis had significantly more symptoms and disability from TMC joint arthrosis than those with incidental TMC joint arthrosis. The best multivariate linear regression model for fewer TMC joint arthrosis-related symptoms and disability included patients with incidental TMC joint arthrosis, male sex, no other painful conditions, less catastrophic thinking, and fewer depressive symptoms and explained 74% of the variability. Having incidental TMC joint arthrosis (25%) and more adaptive coping strategies (less catastrophic thinking; 5%) were the most important contributors to fewer symptoms and less disability. Future studies are merited to determine whether training in better coping strategies (eg, less catastrophic thinking and fewer depressive symptoms) can decrease symptoms and disability in patients with TMC joint arthrosis.

    Purpose Mutational load of susceptibility variants has not been studied on a genomic scale in a clinical population, nor has the potential to identify these mutations as incidental findings during clinical testing been systematically ascertained. Methods Array comparative genomic hybridization, a method for genome-wide detection of DNA copy-number variants, was performed clinically on DNA from 9,005 individuals. Copy-number variants encompassing or disrupting single genes were identified and analyzed for their potential to confer predisposition to dominant, adult-onset disease. Multigene copy-number variants affecting dominant, adult-onset cancer syndrome genes were also assessed. Results In our cohort, 83 single-gene copy-number variants affected 40 unique genes associated with dominant, adult-onset disorders and unrelated to the patients’ referring diagnoses (i.e., incidental) were found. Fourteen of these copy-number variants are likely disease-predisposing, 25 are likely benign, and 44 are of unknown clinical consequence. When incidental copy-number variants spanning up to 20 genes were considered, 27 copy-number variants affected 17 unique genes associated with dominant, adult-onset cancer predisposition. Conclusion Copy-number variants potentially conferring susceptibility to adult-onset disease can be identified as incidental findings during routine genome-wide testing. Some of these mutations may be medically actionable, enabling disease surveillance or prevention; however, most incidentally observed single-gene copy-number variants are currently of unclear significance to the patient.

    Previous research suggests that how people feel throughout the course of a day (i.e. incidental affect) is predictive of exercise behaviour. A mostly separate literature suggests that exercise can lead to more positive incidental affect. This study examines the potential reciprocal effects of incidental affect and exercise behaviour within the same day. Fifty-nine low-active (exercise exercise promotion programme. Ecological momentary assessment was used to record self-reported exercise sessions in real time and incidental affective valence (feeling good/bad) as assessed by the 11-point Feeling Scale at random times throughout the day. Use of a within-subjects cross-lagged, autoregressive model showed that participants were more likely to exercise on days when they experienced more positive incidental affect earlier in the day (b = .58, SE = .10, p exercised (b = .26, SE = .03, p exercising are reciprocally influential within the course of a day.

    Computed tomography (CT) scans are frequently used in managing traumatic brain injuries in children. To assess incidental findings in children with head trauma undergoing CT scan and to describe any associated clinical ramifications. Retrospective review of 524 children treated in 2 emergency departments for closed head injury who received a CT scan. Overall, 137 (26.2%) patients had an incidental finding on CT scan. The most common incidental finding was sinus opacification with an air fluid level (115/137, 83.9%). Thirty-five interventions were reported in children with incidental findings. Children 2 years old or younger were more likely to receive a prescription for antibiotics (relative risk [RR] = 2.66, 95% confidence interval [CI] = 1.08-6.51) and be referred to a specialist (RR = 10.26, 95% CI = 3.56-29.56) than older children. Incidental findings in minor head trauma are common. Clinicians should be prepared to address these findings if clinically indicated.

    Full text: The incidental discovery of colonic polyps, colonic malignancy, diverticulitis and inflammation during PET scanning is well described. This study is a retrospective review of the incidence and follow up of incidental focal FOG uptake in the colon detected during routine PET scanning. PET scan reports over 12 months were reviewed for the reporting of incidental colonic uptake and then clinical follow up performed in available patient records for the incidence of further colonic investigation and results. In 2008, 1985 PET scans were reported at the Royal Adelaide Hospital for the staging and detection of malignancy. Review of the results show that incidental focal colonic uptake was seen in 27 cases, (II female aged 56-83 years). Follow up colonoscopy was performed in 8 cases and in 4 cases showed tubulovillous adenomas, 7-9 mm in size, in the region of abnormal FOG uptake, I had divetticulae and another focal inflammation. Two colonoscopies revealed no abnormality (25% false negative rate). One patient with Head and Neck cancer did not have colonoscopy but the colonic lesion resolved on a post therapy PET scan. Of the 18 cases that did not have colonoscopic follow up 5 were reported on the PET scan to have diffuse probably physiological caecal activity but 13 had focal lesions in the large bowel. Although incidental colonic lesions were detected in only 1.3% of studies, of those having colonoscopy 75 % had significant findings.

    Full Text Available Abstract Background To describe a rare manifestation of mantle cell lymphoma (MCL in conjunctiva, with clinical, hisologic, immunohistologic and genetic findings together with review of the Literature. Case presentation Most ocular adnexal lymphomas are extranodal marginal zone B-cell lymphomas of mucosa-associated lymphoid tissue (MALT. A few cases of ocular adnexal mantle cell lymphomas have been reported in the literature. We present a case of mantle cell lymphoma presenting as right conjunctival mass of at least three months duration in a 64-year-old man. Histopathologic examination showed a proliferation of monomorphous small-to-medium-sized lymphoid cells with cleaved nuclei in the subconjunctiva. By immunohistochemistry, the infiltrate was positive for CD20, CD5, BCL-2, cyclin D1, and the transcription factor SOX11. Fluorescent in situ hybridization demonstrated the presence of IGH-CCND1 fusion indicating t(11;14. Conclusion A rigorous approach to initial diagnosis and staging of small cell lymphomas of the ocular adnexa is needed. The recognition of ocular MCL requires appropriate immunohistochemical staining and/or genetic confirmation to differentiate this rare form of presentation of MCL from other more frequent small cell lymphomas.

    Research has demonstrated that two types of affect have an influence on judgment and decision making: incidental affect (affect unrelated to a judgment or decision such as a mood) and integral affect (affect that is part of the perceiver's internal representation of the option or target under consideration). So far, these two lines of research have seldom crossed so that knowledge concerning their combined effects is largely missing. To fill this gap, the present review highlights differences and similarities between integral and incidental affect. Further, common and unique mechanisms that enable these two types of affect to influence judgment and choices are identified. Finally, some basic principles for affect integration when the two sources co-occur are outlined. These mechanisms are discussed in relation to existing work that has focused on incidental or integral affect but not both.

    2013-01-01

    Full Text Available Fungal corneal ulcers mostly occur after incidental corneal trauma by plant leaves in farm lands or the use of topical corticosteroids or antibiotics. The infection is more prevalent among farmers and harvesters and in some parts of the world is considered as an occupational disease; however, there have been a few reports on the occurrence of such ulcers in healthy individuals after incidental spillage of vegetative material into the eye. The importance of these ulcers is their long-term and refractory course, which makes the visual prognosis unfavorable in most patients, even after appropriate antifungal therapy or ocular interventions. Herein, we present two rare cases of fungal ulcers caused by incidental spillage of vegetative material into the eye while eating nuts and corn. We also discuss the diagnostic and therapeutic approaches, as well as visual outcome reviewing the relevant literature.

    To demonstrate incidental findings and scoliosis on whole-body MRI (WBMRI) in patients with neurofibromatosis type 1 and 2 (NF1 and NF2, respectively), and schwannomatosis. Institutional review board approval and written informed consent were obtained for this prospective HIPAA-compliant study. A total of 247 subjects (141 with NF1, 55 with NF2, 51 with schwannomatosis; 132 women (53.5%); mean age, 41 years, range, 18-97 years) underwent WBMRI using coronal STIR (TR/TE: 4190/111 ms, TI: 150 ms) and T1-weighted images (TR/TE: 454/10 ms), 10-mm slice thickness, imaging time {proportional_to}40 min. Images were reviewed for the presence of incidental findings, outside of nerve sheath tumors. The presence of scoliosis was recorded and curve morphology was assessed and quantified. Incidental findings other than scoliosis were recorded in 104/247 (42%) patients, most often affecting the musculoskeletal system (65/247 patients, 26%). We found 16/247 (6.5%) significant incidental findings likely to affect clinical management, including avascular necrosis of bone in eight patients (five with NF2), eight insufficiency fractures, and four non-neurogenic neoplasms (Hodgkin's lymphoma, liposarcoma, dermoid cyst, large uterine myoma requiring excision). Scoliosis was seen in 50/247 patients (20%), including 8/55 with NF2 (15%) and 11/51 with schwannomatosis (22%). Incidental findings in the neurofibromatoses frequently involve the skeleton. Given the relatively high incidence of unsuspected osteonecrosis and stress fractures, close attention to the skeleton on WBMRI is advised. In addition, knowledge of common incidental findings can help clinicians prepare patients who undergo WBMRI for potential unexpected findings. (orig.)

  11. Incidental Syringomas of the Scalp in a Patient with Scarring Alopecia

    Directory of Open Access Journals (Sweden)

    Kristyn Deen

    2015-07-01

    Full Text Available Syringomas are benign adnexal neoplasms of eccrine lineage, which occur most commonly in the periorbital region in middle-aged females. These cutaneous lesions rarely occur on the scalp, are typically asymptomatic and are predominantly of cosmetic significance. Involvement of the scalp may be indistinguishable from that of scarring alopecia. We present an unusual case of clinically inapparent syringomas occurring on the scalp of a 56-year-old female with alopecia who was subsequently diagnosed with lichen planopilaris after repeated scalp biopsy. In patients with unexplained hair loss, or in cases that are refractive to treatment, clinicians should perform scalp biopsy to exclude the diagnosis of rare neoplastic lesions like syringomas and to diagnose associated conditions.

    Full Text Available PET/MRI is a new hybrid imaging modality and has the potential to become a powerful imaging tool. It is currently one of the most active areas of research in diagnostic imaging. The characterisation of an incidental renal lesion can be difficult. In particular, the differentiation of an oncocytoma from other solid renal lesions such as renal cell carcinoma (RCC represents a diagnostic challenge. We describe the detection of an incidental renal oncocytoma in a 79-year gentleman who underwent a re-staging 18F-Choline PET/MRI following a rise in PSA values (4.07, nadir 1.3.

  13. [Effect of chlorpromazine and amphetamine on incidental memory and its relation to the introvert-extravert structure of personality].

    Science.gov (United States)

    Zaimov, K; Kokoshkarova, A

    1978-10-01

    A total of fifty-four test subjects divided into one control group and two experimental groups were used to study the effects of chlorpromazine and amphetamine upon the incidental memory, its accuracy, and possible dependence on the introversive or extroversive personality structure, respectively. It has been found that chlorpromazine tends to lessen the incidental memory in extent and increase the number of allomnesias or instances of inaccurate remembrance, whereas amphetamine has the effects of increasing the extent of the incidental memory and reducing the number of allomnesias. A comparison of the extent of the incidental memory with the structure of personality in respect of introversion or extroversion in the control group also showed significant differences, the incidental memory being of smaller extent in the case of introversion and greater extent in the case of extroversion.

    Adrenal glands are common sites of diseases. With dramatically increased use of computed tomography (CT) and magnetic resonance (MR) imaging, more and more uncommon adrenal masses have been detected incidentally at abdominal examinations performed for other purposes. In this article, uncommon adrenal masses are classified as cystic masses (endothelial cysts, epithelial cysts, parasitic cysts, and pseudocysts), solid masses (ganglioneuroma, ganglioneuroblastoma, extramedullary plasmacytoma (EMP), neurilemmoma, and lymphoma), fat-containing masses (myelolipoma, teratoma), and infectious masses (tuberculoma), and the imaging features of these uncommon masses are demonstrated. Although most of these lesions do not have specific imaging features, some fat-containing masses and cystic lesions present with characteristic appearances, such as myelolipoma, teratoma, and hydatid. Combination with histopathologic characteristic of these uncommon masses of adrenal gland, radiological features of these lesions on CT and MR imaging can be accurately understood with more confidences. Moreover, CT and MRI are highly accurate in localization of uncommon adrenal masses, and useful to guide surgical treatments

    Left ventricular mass (LVM) at cardiac magnetic resonance imaging (CMR) is a frequent end point in clinical trials in nephrology. Trial participants with end stage renal disease (ESRD) may have a greater frequency of incidental findings (IF). We retrospectively investigated prevalence of IF in previous research CMR and reviewed their subsequent impact on participants. Between 2002 and 2006, 161 ESRD patients underwent CMR in a transplant assessment study. Images were used to assess LV mass and function. In the current study a radiologist reviewed the scans for IF. Review of patient records determined the subsequent clinical significance of IF. There were 150 IF in 95 study participants. Eighty-four (56 %) were new diagnoses. One hundred and two were non-cardiac. Fifteen were suspicious of malignancy. There was a clinically significant IF for 14.9 % of the participants. In six cases earlier identification of an IF may have improved quality of life or survival. Without radiology support clinically important IF may be missed on CMR. Patients undergoing CMR in trials should be counselled about the frequency and implications of IF. Patients with ESRD have a higher prevalence of IF than reported in other populations. Nephrology studies require mechanisms for radiologist reporting and strategies for dealing with IF. (orig.)

    2016-05-01

    Hidradenocarcinoma (HAC) is a rare adenexal tumor with a propensity for the head and neck region and extremities. We report a case of hidradenocarcinnoma in a 56-year-old woman with a mass on her right palm sampled by fine-needle aspiration and later confirmed on histological examination. Fine-needle aspiration cytology revealed a dual population of cells including polyhedral eosinophilic cells and glycogen containing cells with pale/clear cytoplasm. The nuclei were pleomorphic with prominent nucleoli. Occassional papillary structures were identified on the cell block material. A series of immunohistochemical stains were performed and an adnexal neoplasm was suggested. The mass was resected. On histologic sections, infiltration into the adjacent soft tissue was identified. After an additional series of immunohistochemical stains, the diagnosis was confirmed as a HAC. Herein, we present our findings and discuss the differential diagnoses. © 2016 Wiley Periodicals, Inc.

    2003-03-01

    Full Text Available Abstract Background Patients presenting in the emergency room with flank pain suggestive of acute ureteric colic may have alternative underlying conditions mimicking ureteric stones. An early diagnosis and appropriate treatment for other causes of flank pain is important. The majority of centers around the world are increasingly using un-enhanced helical CT (UHCT for evaluation of ureteric colic. This study was conducted to determine the incidence and spectrum of significant incidental diagnoses established or suggested on UHCT performed for suspected renal/ureteric colic. Methods Urologist and radiologist reviewed 233 consecutive UHCT, performed for suspected renal/ureteral colic along with assessment of the medical records. Radiological diagnoses of clinical entities not suspected otherwise were analyzed. All other relevant radiological, biochemical and serological investigations and per-operative findings were also noted. Results Ureteral calculi were identified in 148 examinations (64%, findings of recent passage of calculi in 10 (4% and no calculus in 75 examinations (32%. Overall the incidental findings (additional or alternative diagnosis were found in 28 (12% CT scans. Twenty (71% of these diagnoses were confirmed by per-operative findings, biopsy, and other radiological and biochemical investigations or on clinical follow up. Conclusion A wide spectrum of significant incidental diagnoses can be identified on UHCT performed for suspected renal/ureteral colic. In the present series of 233 consecutive CT examinations, the incidence of incidental diagnosis was 12%.

  8. Incidental internal carotid artery calcifications on temporal bone CT in children

    International Nuclear Information System (INIS)

    Koch, Bernadette; Jones, Blaise; Blackham, Aaron

    2007-01-01

    Incidental internal carotid artery (ICA) calcifications are occasionally noted on CT images of the brain and temporal bone. In adults, incidental calcifications have been correlated with increased incidence of hypercholesterolemia, cardiac disease, diabetes and carotid stenosis. To determine the incidence of incidental calcifications of the carotid siphon on temporal bone CT in children. We retrospectively reviewed 24 months of consecutive temporal bone CT examinations in children aged 18 years and younger. CT examinations on 663 patients were reviewed and the presence or absence of ICA calcifications was ranked as absent, questionable or definitive. In patients in whom definitive calcifications were identified, hospital charts were reviewed for evidence of diabetes mellitus, hypercholesterolemia, hypertriglyceridemia, hyperlipidemia and chronic renal disease as potential causes of early atherosclerosis. Of the 663 patients, 25% had definitive calcifications within the wall of the ICA: 6% of children younger than 2 years and 28% of children 12-19 years of age. Incidentally noted ICA calcifications are a common finding on temporal bone CT in children, most likely a physiologic response to turbulent flow at natural bends in the artery rather than secondary to underlying disease predisposing to early atherosclerotic calcification.

    Conclusion: Incidental PC in men aged ≤ 65 years is not uncommon. Our results suggest that TURP specimens in men aged ≤ 65 years should be completely assessed. Underidentification of cancer may occur as a result of increasing use of laser prostatectomy and the consequent loss of tissue for pathological examination.

    Full Text Available In emergency services a significant amount of pediatric patients undergoa brain or orbit CT scans for suspicion other than sinusitis. Assuming thispremise, this study was held to show the incidental findings of the paranasalsinuses of children with nonspecific symptoms such as fever, headache andvomiting that underwent brain or orbits CT scans, without the initial suspicion of sinusitis. In a retrospective study, we evaluated 70 CT scans of the brainand orbits of children between 0 and 12 years. The incidental findings of theparanasal sinuses occurred in 32 cases (45.7%. Mucosal thickening was themost common incidental finding, being observed in 35% of patients, followed bycomplete opacification observed in 28% of cases and incomplete opacificationobserved in 28% of patients. Bilateral involvement occurred in 78% patients.The sinuses most frequently affected were the maxillary sinus followed byethmoid sinuses. The abnormalities were more severe in children under theage of three years. The prevalence of incidental tomographic abnormalities inpatients without an initial diagnosis of sinusitis is high. The predominance ofthese findings are mild abnormalities.

  9. The role of demographic compensation theory in incidental take assessments for endangered species

    Science.gov (United States)

    McGowan, Conor P.; Ryan, Mark R.; Runge, Michael C.; Millspaugh, Joshua J.; Cochrane, Jean Fitts

    2011-01-01

    Many endangered species laws provide exceptions to legislated prohibitions through incidental take provisions as long as take is the result of unintended consequences of an otherwise legal activity. These allowances presumably invoke the theory of demographic compensation, commonly applied to harvested species, by allowing limited harm as long as the probability of the species' survival or recovery is not reduced appreciably. Demographic compensation requires some density-dependent limits on survival or reproduction in a species' annual cycle that can be alleviated through incidental take. Using a population model for piping plovers in the Great Plains, we found that when the population is in rapid decline or when there is no density dependence, the probability of quasi-extinction increased linearly with increasing take. However, when the population is near stability and subject to density-dependent survival, there was no relationship between quasi-extinction probability and take rates. We note however, that a brief examination of piping plover demography and annual cycles suggests little room for compensatory capacity. We argue that a population's capacity for demographic compensation of incidental take should be evaluated when considering incidental allowances because compensation is the only mechanism whereby a population can absorb the negative effects of take without incurring a reduction in the probability of survival in the wild. With many endangered species there is probably little known about density dependence and compensatory capacity. Under these circumstances, using multiple system models (with and without compensation) to predict the population's response to incidental take and implementing follow-up monitoring to assess species response may be valuable in increasing knowledge and improving future decision making.

    Current guidelines recommend the use of anticoagulant therapy in patients with symptomatic splanchnic vein thrombosis (SVT) and suggest no routine anticoagulation in those with incidental SVT. We used the RIETE (Registro Informatizado Enfermedad Trombo Embólica) registry to assess the rate and severity of symptomatic venous thromboembolism (VTE) recurrences and major bleeding events appearing during the course of anticoagulation in patients with symptomatic or incidental SVT. In March 2017, 521 patients with SVT were recruited. Of them, 212 (41%) presented with symptomatic SVT and 309 had incidental SVT. Most (93%) patients received anticoagulant therapy (median, 147 days). During the course of anticoagulation, 20 patients developed symptomatic VTE recurrences (none died) and 26 had major bleeding (fatal bleeding, 5). On multivariable analysis, patients with incidental SVT had a non-significantly higher risk for symptomatic VTE recurrences (adjusted hazard ratio [HR]: 2.04; 95%CI: 0.71-5.88) and a similar risk for major bleeding (HR: 1.12; 95%CI: 0.47-2.63) than those with symptomatic SVT. Active cancer was associated with at increased risk for VTE recurrences (HR: 3.06; 95%CI: 1.14-8.17) and anaemia (HR: 4.11; 95%CI: 1.45-11.6) or abnormal prothrombin time (HR: 4.10; 95%CI: 1.68-10.1) were associated with at increased risk for major bleeding. The rates of recurrent SVT and major bleeding were similar between patients with incidental or symptomatic SVT. Because the severity of bleeding complications during anticoagulation may outweigh the severity of VTE recurrences in both groups, further studies should identify those SVT patients who benefit from anticoagulant therapy.

    Full Text Available Dynamic assessment (DA, stemmed from both Vygotsky’s (1978 learning theory and Feuerstein’s (1979 theory of mediated learning experiences, is an alternative to static assessment. It focuses on both instruction and assessment aiming at promoting learning through mediation.  DA has been widely researched in different linguistic areas, but there is paucity of research on its practice in ESP contexts. Accordingly, this study investigated the effectiveness of DA on incidental vocabularies emerging in technical reading textbooks, written for electronic engineering students. The study employed a quasi-experimental research design. Due to sample selection problems, an intact group of 25 BA electronic students were selected from the University of Zanjan. A pre-test was administered to check whether they had previous knowledge of the target words, incidentally acquired during the reading activity. As for the instrument stage, DA procedures were utilized in order to individualize participants’ assessment. Following DA implementation, a post-test similar in content to pre-test, was administered to the same participants. The significance of DA for the enhancement of incidental vocabularies was to make participants aware of the strategies of identifying, evaluating and monitoring vocabularies (Nassaji, 2003 through mediation process.  The results indicated that participants' incidental vocabulary learning promoted dramatically using DA, which employed structured hints for the mediation process.  The results of this study can inform both teachers and learners to provide a step by step procedure to promote both teaching and assessment of ESP learners' vocabulary.

    Even though numerous cases of massive thromboemboli have been reported in the literature, intracardiac thromboemboli (ICTs) incidentally found during orthotopic liver transplantation (OLT) have not been examined. In this study, we retrospectively examined the incidence, risk factors, and management of incidental ICTs during OLT. After institutional review board approval, adult patients who underwent OLT between January 2004 and December 2008 at our center were reviewed. ICTs were identified and confirmed by the examination of OLT datasheets, anesthesia records, and recorded transesophageal echocardiography (TEE) clips. The clinical presentation, management, and outcomes of the patients with ICTs were reviewed. Risk factors were analyzed by multivariate logistic regression. During the study period, 426 of the 936 adult OLT patients (45.5%) underwent intraoperative TEE monitoring. Incidental ICTs were identified in 8 of these 426 patients (1.9%). Two ICTs occurred before reperfusion, and 6 ICTs occurred after reperfusion. The treatment was at the discretion of the treating physicians; however, none of the patients received an anticoagulant or thrombolytics. Multivariate analysis identified 2 independent risk factors for intraoperative incidental ICTs: the presence of symptomatic or surgically treated portal hypertension (a history of gastrointestinal bleeding, a transjugular intrahepatic portosystemic shunt procedure, or portocaval shunt surgery) before OLT and intraoperative hemodialysis (odds ratios of 4.05 and 7.29, respectively; P ICTs during OLT occurred at a rate of 1.9% and were associated with several preoperative and intraoperative risk factors. The use of TEE allows early identification, which may be important. Our management for incidental ICTs is described; however, no conclusions can be made about the optimal therapy.

  13. Incidental Learning: A Brief, Valid Measure of Memory Based on the WAIS-IV Vocabulary and Similarities Subtests.

    2016-12-01

    We assessed the validity of a brief incidental learning measure based on the Similarities and Vocabulary subtests of the Wechsler Adult Intelligence Scale-Fourth Edition (WAIS-IV). Most neuropsychological assessments for memory require intentional learning, but incidental learning occurs without explicit instruction. Incidental memory tests such as the WAIS-III Symbol Digit Coding subtest have existed for many years, but few memory studies have used a semantically processed incidental learning model. We conducted a retrospective analysis of 37 veterans with traumatic brain injury, referred for outpatient neuropsychological testing at a Veterans Affairs hospital. As part of their evaluation, the participants completed the incidental learning tasks. We compared their incidental learning performance to their performance on traditional memory measures. Incidental learning scores correlated strongly with scores on the California Verbal Learning Test-Second Edition (CVLT-II) and Brief Visuospatial Memory Test-Revised (BVMT-R). After we conducted a partial correlation that controlled for the effects of age, incidental learning correlated significantly with the CVLT-II Immediate Free Recall, CVLT-II Short-Delay Recall, CVLT-II Long-Delay Recall, and CVLT-II Yes/No Recognition Hits, and with the BVMT-R Delayed Recall and BVMT-R Recognition Discrimination Index. Our incidental learning procedures derived from subtests of the WAIS-IV Edition are an efficient and valid way of measuring memory. These tasks add minimally to testing time and capitalize on the semantic encoding that is inherent in completing the Similarities and Vocabulary subtests.

    The widespread use of high-resolution cross-sectional imaging such as computed tomography (CT) and magnetic resonance imaging (MRI) for the investigation of the abdomen is associated with an increasing detection of incidental adrenal masses. We evaluated the ability of {sup 18}F-fluorodeoxyglucose positron emission tomography to distinguish benign from malignant adrenal masses when CT or MRI results had been inconclusive. We included only patients with no evidence of hormonal hypersecretion and no personal history of cancer or in whom previously diagnosed cancer was in prolonged remission. PET/CT scans were acquired after 90 min (mean, range 60-140 min) after FDG injection. The visual interpretation, maximum standardised uptake values (SUVmax) and adrenal compared to liver uptake ratio were correlated with the final histological diagnosis or clinico-radiological follow-up when surgery had not been performed. Thirty-seven patients with 41 adrenal masses were prospectively evaluated. The final diagnosis was 12 malignant, 17 benign tumours, and 12 tumours classified as benign on follow-up. The visual interpretation was more accurate than SUVmax alone, tumour diameter or unenhanced density, with a sensitivity of 100% (12/12), a specificity of 86% (25/29) and a negative predictive value of 100% (25/25). The use of 1.8 as the threshold for tumour/liver SUVmax ratio, retrospectively established, demonstrated 100% sensitivity and specificity. FDG PET/CT accurately characterises adrenal tumours, with an excellent sensitivity and negative predictive values. Thus, a negative PET may predict a benign tumour that would potentially prevent the need for surgery of adrenal tumours with inconclusive conventional imaging. (orig.)

  19. Prevalence of incidental prostate cancer: A systematic review of autopsy studies

    2015-01-01

    Prostate cancer screening may detect nonprogressive cancers, leading to overdiagnosis and overtreatment. The potential for overdiagnosis can be assessed from the reservoir of prostate cancer in autopsy studies that report incidental prostate cancer rates in men who died of other causes. We aimed to estimate the age-specific incidental cancer prevalence from all published autopsy studies. We identified eligible studies by searches of Medline and Embase, forward and backward citation searches and contacting authors. We screened the titles and abstracts of all articles; checked the full-text articles for eligibility and extracted clinical and pathology data using standardized forms. We extracted mean cancer prevalence, age-specific cancer prevalence and validity measures and then pooled data from all studies using logistic regression models with random effects. The 29 studies included in the review dated from 1948 to 2013. Incidental cancer was detected in all populations, with no obvious time trends in prevalence. Prostate cancer prevalence increased with each decade of age, OR = 1.7 (1.6–1.8), and was higher in studies that used the Gleason score, OR = 2.0 (1.1–3.7). No other factors were significantly predictive. The estimated mean cancer prevalence increased in a nonlinear fashion from 5% (95% CI: 3–8%) at age 79 years. There was substantial variation between populations in estimated cancer prevalence. There is a substantial reservoir of incidental prostate cancer which increases with age. The high risk of overdiagnosis limits the usefulness of prostate cancer screening. What’s new? Before symptoms of prostate cancer manifest clinically, many men die of other causes. Yet, prostate screening, particularly in older men, frequently turns out positive, resulting in overdiagnosis and overtreatment. This meta-analysis of published autopsy studies shows that incidental prostate cancer increases with age and with the use of sensitive screening strategies

  20. "Incidental fear cues increase monetary loss aversion": Correction to Schulreich, Gerhardt, and Heekeren (2016).

    Science.gov (United States)

    2016-12-01

    Reports an error in "Incidental fear cues increase monetary loss aversion" by Stefan Schulreich, Holger Gerhardt and Hauke R. Heekeren ( Emotion , 2016[Apr], Vol 16[3], 402-412). In the current article, there was an error in the Study 2 portion of the article. The fourth paragraph of the Results section should read as follows: Performing the same analyses as in Study 1, we found an effect of incidental fear cues on decision behavior. Participants accepted fewer gambles in the fearful-face condition (32.77%) than in the neutral-face condition (33.96%), with Z = -2.187, p = .027, d = -0.998 in the Wilcoxon signed-ranks test and β = 0.012, SE = 0.0053, F(1, 21) = 4.434, p = .047, partial η² = .174 in the linear regression. This suggests increased risk aversion in the fearful-face condition. Concerning personality, however, there were no significant between-subjects effects or between-within interaction effects (all ps = .349). (The following abstract of the original article appeared in record 2015-52358-001.) In many everyday decisions, people exhibit loss aversion-a greater sensitivity to losses relative to gains of equal size. Loss aversion is thought to be (at least partly) mediated by emotional-in particular, fear-related-processes. Decision research has shown that even incidental emotions, which are unrelated to the decision at hand, can influence decision making. The effect of incidental fear on loss aversion, however, is thus far unclear. In two studies, we experimentally investigated how incidental fear cues, presented during (Study 1) or before (Study 2) choices to accept or reject mixed gambles over real monetary stakes, influence monetary loss aversion. We find that the presentation of fearful faces, relative to the presentation of neutral faces, increased risk aversion-an effect that could be attributed to increased loss aversion. The size of this effect was moderated by psychopathic personality: Fearless dominance, in particular its interpersonal facet

    2012-01-01

    Full Text Available Background: Renal papillary adenoma is usually an incidental finding at autopsy with an incidence of 7% to 23%. The frequency of small papillary tumours of kidney increases with age to approximately 40% of the population over the age of 65. These tumours occur morefrequently in scarred kidneys, acquired renal cystic disease and in children with von Hippel-Lindau syndrome. Case history: In this report we describe renal papillary adenoma incidentally detected during autopsies of two elderly males. Gross examination of kidneyshowed two tiny subcapsular yellowish nodules in one case and single nodule with similar morphology in the other. Microscopic examination in both the cases showed a well circumscribed tumour composed of densely packed tubules and papillae lined by small cuboidal to columnar cells with rounded uniform nuclei. However there was no nuclear atypia, mitosis or necrosis.

    We examined the frequency of incidentally found or unexpected tumors discovered at the time of magnetic resonance imaging (MRI) examinations in the temporomandibular joint (TMJ) region for patients with suspicion of TMJ arthrosis. Five MR images (T1-weighted transverse scout image and proton density and T2-weighted oblique sagittal images at the open and closed mouth) were acquired. In 2776 MRI examinations of TMJ arthrosis, two tumors were discovered. They consisted of an adenoid cystic carcinoma in the deep portion of the parotid gland, and a malignant tumor extending from the infratemporal fossa to the parapharyngeal space. The rate of incidentally founded or unexpected tumors in TMJ examinations was low (0.072%), but the two tumors found were malignant tumors, and therefore, scout image should be carefully examined, not only used for positing the slice

    We examined the frequency of incidentally found or unexpected tumors discovered at the time of magnetic resonance imaging (MRI) examinations in the temporomandibular joint (TMJ) region for patients with suspicion of TMJ arthrosis. Five MR images (T1-weighted transverse scout image and proton density and T2-weighted oblique sagittal images at the open and closed mouth) were acquired. In 2776 MRI examinations of TMJ arthrosis, two tumors were discovered. They consisted of an adenoid cystic carcinoma in the deep portion of the parotid gland, and a malignant tumor extending from the infratemporal fossa to the parapharyngeal space. The rate of incidentally founded or unexpected tumors in TMJ examinations was low (0.072%), but the two tumors found were malignant tumors, and therefore, scout image should be carefully examined, not only used for positing the slice.

    2012-01-01

    We combined an item-method directed forgetting paradigm with a secondary task requiring a response to discriminate the color of probe words presented 1400 ms, 1800 ms or 2600 ms following each study phase memory instruction. The speed to make the color discrimination was used to assess the cognitive demands associated with instantiating Remember (R) and Forget (F) instructions; incidental memory for probe words was used to assess whether instantiating an F instruction also affects items presented in close temporal proximity. Discrimination responses were slower following F than R instructions at the two longest intervals. Critically, at the 1800 ms interval, incidental probe word recognition was worse following F than R instructions, particularly when the study word was successfully forgotten (as opposed to unintentionally remembered). We suggest that intentional forgetting is an active cognitive process associated with establishing control over the contents of working memory. Copyright © 2011 Elsevier B.V. All rights reserved.

    This document addresses the incidental reflector reactivity worth of containerized maintenance/housekeeping fluids for use in PF-4 at Los Alamos National Laboratory (LANL). The intent of the document is to analyze containerized maintenance/housekeeping fluids which will be analyzed as water that may be present under normal conditions of an operation. The reactivity worth is compared to the reactivity worth due to I-inch of close-fitting 4n water reflection and I-inch of close-fitting radial water reflection. Both have been used to bound incidental reflection by 2-liter bottles in criticality safety evaluations. The conclusion is that, when the maintenance/housekeeping fluids are containerized the reactivity increase from a configuration which is bounding of normal conditions (up to eight bottles modeled with 2-liters of solution at varying diameter) is bound by I-inch of close fitting 4n water relection.

  11. Incidental and intentional learning of verbal episodic material differentially modifies functional brain networks.

    Full Text Available Learning- and memory-related processes are thought to result from dynamic interactions in large-scale brain networks that include lateral and mesial structures of the temporal lobes. We investigate the impact of incidental and intentional learning of verbal episodic material on functional brain networks that we derive from scalp-EEG recorded continuously from 33 subjects during a neuropsychological test schedule. Analyzing the networks' global statistical properties we observe that intentional but not incidental learning leads to a significantly increased clustering coefficient, and the average shortest path length remains unaffected. Moreover, network modifications correlate with subsequent recall performance: the more pronounced the modifications of the clustering coefficient, the higher the recall performance. Our findings provide novel insights into the relationship between topological aspects of functional brain networks and higher cognitive functions.

    The purpose of this case report is to describe chiropractic care of an adolescent with acute low back pain and incidental finding of spina bifida occulta managed with high-velocity low-amplitude manipulation. A 10-year-old boy was referred for chiropractic care by his pediatrician for the management of low back pain after a fall 3 days prior. Examination and medical records revealed the patient also had spina bifida occulta at the level of L5. High-velocity low-amplitude treatment for lower back pain showed resolution of patient's pain after 6 visits. No adverse effects were reported. An adolescent patient with lower back pain and incidental finding of spina bifida occulta improved with a course of care that included with high-velocity low-amplitude manipulation therapy.

    Full Text Available The western Mediterranean Sea is an important fishing area for the Spanish drifting longline fleet, targeting swordfish (Xiphias gladius, bluefin tuna (Thunnus thynnus and albacore (T. alalunga. Some seabird species can be captured incidentally as bycatch marine fauna. From July 1999 to August 2000 information on 554 surface longline sets was collected by onboard observers of the Spanish Oceanographic Institute (IEO on 18 longline fishing boats working within the Spanish Mediterranean fishing area. Eleven yellow-legged gulls (Larus cachinnans, 9 Cory´s shearwaters (Calonectris diomedea and 1 Northern gannet (Morus bassanus were captured incidentally. Bycatch rates ranged from 0.002 to 0.023 birds/1000 hooks.

    Dynamic assessment (DA), stemmed from both Vygotsky’s (1978) learning theory and Feuerstein’s (1979) theory of mediated learning experiences, is an alternative to static assessment. It focuses on both instruction and assessment aiming at promoting learning through mediation.  DA has been widely researched in different linguistic areas, but there is paucity of research on its practice in ESP contexts. Accordingly, this study investigated the effectiveness of DA on incidental vocabularies emerg...

    Full Text Available Strandings and incidental catches of four sea turtles species (Chelonia mydas, Lepidochelys olivacea, Dermochelys coriacea and Eretmochelys imbricata were registered in Tumbes Region since August 2007 to August 2009. These registers (52.6% of strandings and 47.4% of incidental catches occurred during all year; most frequently in Punta Picos (50.5%, Canoas (20.0% and Baja de Punta Mero (14.7%. The most registered species were C. mydas (64.2% and L. olivacea (30.5%; their sizes did not present significant differences between areas and climatic seasons. The higher percentage of C. mydas, L. olivacea and D. coriacea were considered sub-adults, including the only specimen of E. imbricata. The incidental catches were made with gillnets of different mesh sizes, but 8 inches mesh was most frequently. A high proportions of specimens were died with signs of drowning (22.2% this was due to the prolonged time of soak time of gillnet (approximately 12 hours. No significant differences in CPUE were found between climatic seasons and no seasonal pattern was evident. Lesions in 14% of stranded specimens were caused possibly by human attacks or by collisions with fishing boats. 77.8% of incidental catch specimens were sacrificed for the commercialization of his meat, and sometimes of his shell, this shows the lack of awareness of conservation. These observations indicate that the coast of Tumbes is an important foraging area and development of sub-adult specimens of sea turtles; so it is recomend to develop monitoring, awareness and critical areas protection programs to foment the conservation of these organisms in the Eastern Pacific.

    2016-01-01

    Full Text Available Context: Thyrotoxicosis is a common clinical problem, and the most common cause of thyrotoxicosis is Graves′ disease and is 4 times more common than the other causes combined. Of late, the number of people incidentally detected to have biochemical thyrotoxicosis is increasing, and most patients are detected during health checkups, pregnancy planning, and surgical fitness. There are no data on the etiology and natural course of such cases and no guidelines for evaluation of such patients. Aims: The aim of this study is to evaluate the cause of thyrotoxicosis in patients incidentally detected to have biochemical thyrotoxicosis and to study the natural course of illness of these patients. Subjects and Methods: All patients who were incidentally detected to have biochemical thyrotoxicosis (during health checkups, pregnancy planning, and surgical fitness were included and studied. Patients who had symptoms of thyrotoxicosis, or patients in whom thyrotoxicosis was suspected by the treating doctor were excluded from the study. All patients underwent an ultrasound thyroid and thyroid scan, and treatment was decided based on the results. All patients were followed up for a minimum period of 3 months. Results: A total of 57 patients were studied. The average age of the study population was 32.8 years, with male:female ratio of 1:3.3. Of 57 patients, 52 (91% had subacute thyroiditis as the cause of thyrotoxicosis while Graves′ disease was seen in 9%. None had toxic adenoma or toxic multinodular goiter. In the patients with subacute thyroiditis, 47 became euthyroid and 5 became subclinically hypothyroid (Stage b. Conclusions: The majority of patients with incidentally detected thyrotoxicosis had thyroiditis as the cause, which reverted to euthyroid state in most of the cases. Based on the study, it seems prudent to wait and follow up this group of patients rather than start antithyroid drugs, especially if facilities for uptake scan are not available or

    To determine the prevalence of incidental findings in healthy subjects of the Cuban Human Brain Mapping Project sample, it was performed a retrospective descriptive study of the magnetic resonance imaging (MRI) obtained from 394 healthy subjects that make up the sample of the project, between 2006-2007, with an age range of 18 to 68 years (mean 33,12), of which 269 (68,27 %) are male and 125 (31,73 %) are women. It was shown that 40,36 % had one or more anomaly in the magnetic resonance imaging (MRI). In total, the number of incidental findings was 188, 23,6 % of which were brain findings and 24,11 % were non-brain findings, among the latter, were the sinusopathy with 20,81 % and maxillary polyps with 3,30 %. The most prevalent brain findings were: intrasellar arachnoidocele, 11,93 %, followed by the prominence of the pituitary gland, 5,84 %, ventricular asymmetry, 1,77 % and bone defects, 1,02 %. Other brain abnormalities found with very low prevalence had no pathological significance, except for two cases with brain tumor, which were immediately sent to a specialist. Incidental findings in MRI are common in the general population (40,36 %), being the sinusopathy, and intrasellar arachnoidocele the most common findings. Asymptomatic individuals who have any type of structural abnormality provide invaluable information on the prevalence of these abnormalities in a presumably healthy population, which may be used as references for epidemiological studies

    Full Text Available Purpose. The increased use of magnetic resonance imaging (MRI has resulted in reports of incidental abnormal bone marrow (BM signal. Our goal was to determine the evaluation of an incidental abnormal BM signal on MRI and the prevalence of a subsequent oncologic diagnosis. Methods. We conducted a retrospective cohort study of patients over age 18 undergoing MRI between May 2005 and October 2010 at Tufts Medical Center (TMC with follow-up through November 2013. The electronic medical record was queried to determine imaging site, reason for scan, evaluation following radiology report, and final diagnosis. Results. 49,678 MRIs were done with 110 patients meeting inclusion criteria. Twenty two percent underwent some evaluation, most commonly a complete blood count, serum protein electrophoresis, or bone scan. With median follow-up of 41 months, 6% of patients were diagnosed with malignancies including multiple myeloma, non-Hodgkins lymphoma, metastatic non-small cell lung cancer, and metastatic adenocarcinoma. One patient who had not undergone evaluation developed breast cancer 24 months after the MRI. Conclusions. Incidentally noted abnormal or heterogeneous bone marrow signal on MRI was not inconsequential and should prompt further evaluation.

    Full Text Available Objective To evaluate intra- and interobserver agreement in the identification of incidental enchondromas at knee magnetic resonance imaging, and to assess the prevalence of imaging findings. Materials and Methods Retrospective study reviewing 326 knee magnetic resonance images acquired in the period between November 2009 and September 2010. The images were independently and blindly analyzed by two specialists in musculoskeletal radiology, with the objective of identifying incidental enchondromas, presence of foci with signal similar to bone marrow and foci of signal absence suggestive of calcifications within the enchondromas. Inter- and intraobserver agreements were analyzed. Results Eleven lesions compatible with enchondromas (3.3% were identified. The interobserver agreement for the presence of enchondroma was high. Prevalence of foci of bone marrow signal inside the enchondromas was of 54.55%, and foci suggestive of calcification corresponded to 36.36%. The intraobserver agreement for foci of bone marrow signal in enchondromas was perfect, and interobserver agreement was high. Conclusion The prevalence of incidental enchondromas in the current study was compatible with data in the literature. Excellent agreement was observed in the identification of enchondromas and in the assessment of imaging findings. A higher prevalence of fat signal foci was observed as compared with signal absence suggestive of calcifications.

    Full Text Available The present study aimed to investigate the effects of implementing two innovative speaking tasks, namely, information-loaded and negotiation-oriented tasks, on the incidental vocabulary acquisition of advanced Iranian EFL learners. To this end, an experimental research was conducted in an English language institute with 30 homogeneous advanced EFL learners randomly divided into two experimental groups. Experimental group I performed some information-loaded tasks using thirty five texts as speaking aids for implementing multicultural experiences, and experimental group II performed some negotiation-oriented tasks utilizing seven argumentative sentences for each topic to promote divergent thinking processes. At the end of the treatment, a vocabulary post-test and a questionnaire were administered to measure the effects of the treatments on the students’ incidental vocabulary knowledge and attitude to the performed tasks in each group. The statistical analysis of the data revealed that the information-loaded tasks group had significantly outperformed the negotiation-oriented tasks group on the vocabulary post-test and had a significantly more positive attitude to the tasks they performed in their class. This study offers some implications for the development of a sizable and profound knowledge of vocabulary in an effortless and pleasant manner. It also fulfils the need of EFL teachers and material developers in their search for some effective activities and techniques that can help to improve EFL learners’ incidental vocabulary knowledge.

    Intestinal malrotation is defined as intestinal nonrotation or incomplete rotation around superior mesenteric artery (SMA), involving anomalies of intestinal fixation as well. The patients may be recognized incidentally during other surgical procedures or at autopsy. Here in, we present a case of midgut malrotation which was diagnosed incidentally during hepaticojejunostomy procedure for benign biliary stricture. A 46 years old male patient was referred to our clinic with failed surgery for biliary stricture due to extensive adhesions. Prior to our surgery, intestinal malrotation was not reported and noticed by the diagnostic tools. When the patient underwent relaparotomy, midgut malrotation was observed. Distruption in the normal embryological development of bowel is the cause of intestinal malrotation. Various anatomic configurations and anomalies resulting from rotation anomalies of midgut. Adult patients are usually asymptomatic and the anomaly is discovered only at autopsy or incidentally at surgery. The role of additional surgery especially in patients with asymptomatic disease related to malrotation is debated. Performing loop hepaticojejunostomy with Braun enteroenterostomy is feasible and acceptable option rather than Roux-N-Y hepaticojejunostomy in case of intestinal malrotation.

  5. Freedom of Choice About Incidental Findings Can Frustrate Participants' True Preferences.

    2016-03-01

    Ethicists, regulators and researchers have struggled with the question of whether incidental findings in genomics studies should be disclosed to participants. In the ethical debate, a general consensus is that disclosed information should benefit participants. However, there is no agreement that genetic information will benefit participants, rather it may cause problems such as anxiety. One could get past this disagreement about disclosure of incidental findings by letting participants express their preferences in the consent form. We argue that this freedom of choice is problematic. In transferring the decision to participants, it is assumed that participants will understand what they decide about and that they will express what they truly want. However, psychological findings about people's reaction to probabilities and risk have been shown to involve both cognitive and emotional challenges. People change their attitude to risk depending on what is at stake. Their mood affects judgments and choices, and they over- and underestimate probabilities depending on whether they are low or high. Moreover, different framing of the options can steer people to a specific choice. Although it seems attractive to let participants express their preferences to incidental findings in the consent form, it is uncertain if this choice enables people to express what they truly prefer. In order to better understand the participants' preferences, we argue that future empirical work needs to confront the participant with the complexity of the uncertainty and the trade-offs that are connected with the uncertain predictive value of genetic risk information. © 2015 John Wiley & Sons Ltd.

    The objective of this study was to determine adherence to incidentally detected lung nodule computed tomographic (CT) surveillance recommendations and identify demographic and clinical factors that increase the likelihood of CT surveillance. A total of 419 patients with incidentally detected lung nodules were included. Recorded data included patient demographic, radiologic, and clinical characteristics and outcomes at a 4-year follow-up. Multivariate logistic regression models determined the factors associated with likelihood of recommended CT surveillance. At least 1 recommended surveillance chest CT was performed on 48% of the patients (148/310). Computed tomographic result communication to the patient (odds ratio [OR], 2.2; P = 0.006; confidence interval [CI], 1.3-4.0) or to the referring physician (OR, 2.8; P = 0.001; CI, 1.7-4.5) and recommendation of a specific surveillance time interval (OR, 1.7; P = 0.023; CI, 1.08-2.72) increased the likelihood of surveillance. Other demographic, radiologic, and clinical factors did not influence surveillance. Documented physician and patient result communication as well as the recommendation of a specific surveillance time interval increased the likelihood of CT surveillance of incidentally detected lung nodules.

    2017-01-01

    Full Text Available Introduction: Maxillary sinus can be visualized in both two-dimensional and three-dimensional images. Computed tomography (CT is considered the gold standard method for the examination of maxillary sinus. Cone beam computed tomography (CBCT addresses the limitation of CT and provides many dental advantages. It can provide valuable knowledge about the pathology with limited exposure and low cost compared with other imaging used for diagnostic purposes. Aims and Objectives: The aim of the study is to analyze the prevalence of pathological changes in maxillary sinus of asymptomatic cases using CBCT for diagnostic purposes. Materials and Methods: This retrospective study evaluated 231 patients for incidental maxillary sinus pathologies. Pathological findings were categorized as mucosal thickening, polypoid mucosal thickening, radiopacification, and no pathological findings. Evaluation of pathological findings was done using factors of age and gender. Results: The present study showed 86 cases with maxillary sinus pathology and 145 cases with no pathological findings. Patients with maxillary sinus pathology were mostly diagnosed with mucosal thickening on both sides. In right maxillary sinus, 45 cases (52.3% showed mucosal thickening, and on the left side 36 cases (41.9% were diagnosed with mucosal thickening. Among 86 cases reported, 20 right maxillary sinus (23.3% and 25 left maxillary sinus (29.1% showed no signs of pathology. Conclusion: The incidental maxillary sinus pathologies are highly prevalent in asymptomatic patients. Therefore, oral radiologists should be aware of these incidental findings which will help in early diagnosis and treatment of disease.

    Full Text Available Incidentes com medicamentos geram problemas aos pacientes e custos adicionais ao sistema de saúde. A variedade de termos utilizada para comunicá-los propicia divergências nos resultados de pesquisas e confundem notificadores. Objetivou-se revisar os termos utilizados para descrever estes incidentes confrontando-os com as conceituações/definições oficiais disponíveis. Pesquisaram-se as bases PubMed, MEDLINE, IPA e LILACS para selecionar estudos publicados entre janeiro de 1990 e dezembro de 2005. Selecionaram-se 33 publicações. Verificou-se que a terminologia supranacional recomendada para descrever incidentes com medicamentos é insuficiente, mas que há consenso de uso das expressões em função do gênero do incidente. O termo Reação Adversa a Medicamento é mais utilizado quando não se verifica intencionalidade. A expressão Evento Adverso a Medicamento foi mais usada quando se descreviam incidentes durante a hospitalização; e Problema Relacionado a Medicamento foi mais utilizada em estudos que avaliaram atenção/cuidados farmacêuticos (uso/falta do medicamento. Ainda assim, a linha divisória entre essas três categorias não é clara e simples.

    An important challenge with the application of next-generation sequencing technology is the possibility of uncovering incidental genomic findings. A paucity of evidence on personal utility for incidental findings has hindered clinical guidelines. Our objective was to estimate personal utility for complex information derived from incidental genomic findings. We used a discrete-choice experiment to evaluate participants' personal utility for the following attributes: disease penetrance, disease treatability, disease severity, carrier status and cost. Study participants were drawn from the Canadian public. We analyzed the data with a mixed logit model. In total, 1200 participants completed our questionnaire (available in English and French). Participants valued receiving information about high-penetrance disorders but expressed disutility for receiving information on low-penetrance disorders. The average willingness to pay was $445 (95% confidence interval [CI] $322-$567) to receive incidental findings in a scenario where clinicians returned information about high-penetrance, medically treatable disorders, but only 66% of participants (95% CI 63%-71%) indicated that they would choose to receive information in that scenario. On average, participants placed an important value ($725, 95% CI $600-$850) on having a choice about what type of findings they would receive, including receipt of information about high-penetrance, treatable disorders or receipt of information about high-penetrance disorders with or without available treatment. The predicted uptake of that scenario was 76% (95% CI 72%-79%). Most participants valued receiving incidental findings, but personal utility depended on the type of finding, and not all participants wanted to receive incidental results, regardless of the potential health implications. These results indicate that to maximize benefit, participant-level preferences should inform the decision about whether to return incidental findings. © 2015

    Since positron emission tomography/computed tomography (PET/CT) has been introduced, many incidental findings have been identified. The aim of this study was to assess the clinical significance of incidental findings on PET/CT in patients with gastric cancer. A total of 421 patients with gastric cancer underwent PET/CT for initial staging. Incidental findings on PET/CT were classified into five categories according to clinical significance--normal variant, benign, probably benign, probably malignant, and definitely malignant. We obtained information regarding follow-up examinations, additional visits, final diagnosis of incidental findings and short-term medical costs for further evaluation. Eight hundred eighty-two incidental findings were detected in 386 (91.7%) patients. Of 274 incidental findings classified as probably benign, probably malignant or definitely malignant, 130 required one or more additional investigations. Finally, 12 (9.2%) were proved to be associated with second primary malignancy or metastasis of gastric cancer. One hundred twenty-nine additional outpatient visits and 10 additional hospitalizations were needed for evaluating the incidental findings. The treatment strategy for gastric cancer was changed in one patient. The estimated cost of additional investigations was $US283 (95% CI: $US248-$US311) per patient. Incidental findings on PET/CT were common. Although the incidental findings were suspicious of malignancy, most were benign with high costs for additional investigations. © 2015 Wiley Publishing Asia Pty Ltd.

    Incidental findings in prenatal diagnostic testing may or may not have clear prognostic significance for the phenotype. We studied experts' opinions of the benefit and disadvantage of an incidental prenatal diagnosis of a sex chromosomal aneuploidy (SCA). We interviewed 16 experts in the field of counseling and treatment of people with SCA and asked 13 clinical geneticists and genetic associates about the clinical relevance of an incidental prenatal diagnosis of SCA. Most of the experts and clinical geneticists (87.5% and 76.9%, respectively) stated that an incidental prenatal diagnosis of SCA was a benefit for the child and the parents. They acknowledged the possibility of parental decisions to terminate pregnancy. Expert options in screening, training, and treatment of health, behavior, and fertility problems increase with an early diagnosis of SCA. Most experts favored an incidental prenatal diagnosis of SCA despite the complex counseling issues and their acknowledgment of possible parental decisions to terminate pregnancy. They believed the benefits greatly outweigh the disadvantages. © 2012 John Wiley & Sons, Ltd.

  12. Defining the Parameters of Incidental Learning on a Serial Reaction Time (SRT) Task: Do Conscious Rules Apply?

    Barker, Lynne A

    2012-12-17

    There is ongoing debate about the contribution of explicit processes to incidental learning, particularly attention, working memory and control mechanisms. Studies generally measure explicit process contributions to incidental learning by comparing dual- to single-task sequence learning on some variant of a Serial Reaction Time (SRT), usually adopting an auditory tone counting task as the secondary task/memory load. Few studies have used secondary working memory stimuli with the SRT task, those that have typically presented secondary stimuli, before, after or between primary task stimuli. Arguably, this design is problematic because participants may potentially "switch" attention between sequential stimulus sources limiting the potential of both tasks to simultaneously index shared cognitive resources. In the present study secondary Visual and Verbal, memory tasks were temporally synchronous and spatially embedded with the primary SRT task for Visual and Verbal dual-task conditions and temporally synchronous but spatially displaced for Visual-Spatial and Verbal-Spatial Above/Below conditions, to investigate modality specific contributions of visual, verbal and spatial memory to incidental and explicit sequence learning. Incidental learning scores were not different as an effect of condition but explicit scores were. Explicit scores significantly and incrementally diminished from the Single-task through Visual-Spatial Below conditions; percentage accuracy scores on secondary tasks followed a significant corresponding pattern suggesting an explicit learning/secondary memory task trade-off as memory demands of tasks increased across condition. Incidental learning boundary conditions are unlikely to substantially comprise working memory processes.

  13. Incidental durotomy in lumbar spine surgery - incidence, risk factors and management

    Full Text Available Incidental durotomy is a common complication of lumbar spine operations for degenerative disorders. Its incidence varies depending on several risk factors and regarding the intra and postoperative management, there is no consensus. Our objective was to report our experience with incidental durotomy in patients who were operated on for lumbar disc herniation, lumbar spinal stenosis and revision surgeries. Between 2009 and 2012, 1259 patients were operated on for degenerative lumbar disorders. For primary operations, the surgical approach was mino-open, interlamar, uni- or bilateral, as for recurrences, the removal of the compressive element was intended: the epidural scar and the disc fragment. 863 patients (67,7% were operated on for lumbar disc herniation, 344 patients (27,3% were operated on for lumbar spinal stenosis and 52 patients (5% were operated for recurrences. The operations were performed by neurosurgeons with the same professional degree but with different operative volume. Unintentional durotomy occurred in 20 (2,3% of the patients with herniated disc, in 14 (4,07% of the patients with lumbar spinal stenosis and in 12 (23% of the patients who were operated on for recurrences. The most frequent risk factors were: obesity, revised surgery and the physician’s low operative volume. Intraoperative dural fissures were repaired through suture (8 cases, by applying muscle, fat graft or by applying curaspon, tachosil. There existed 4 CSF fistulas which were repaired at reoperation. Incidental dural fissures during operations for degenerative lumbar disorders must be recognized and immediately repaired to prevent complications such as CSF fistula, osteodiscitis and increased medical costs. Preventing, identifying and treating unintentional durotomies can be best achieved by respecting a neat surgical technique and a standardized treatment protocol.

    2009-07-01

    Pleuropulmonary blastoma (PPB) is an aggressive tumour accounting for less than 1% of all primary malignant lung tumours in the paediatric population. It can be associated with cystic pulmonary lesions, which may be evident at the time of diagnosis or predate the appearance of the tumour. There are contradictory reports about the value of prophylactic resection of pulmonary cysts in protecting patients from developing PPB. We report an individual case where asymptomatic congenital lobar emphysema was incidentally picked up on CXR. Following a period of surveillance the lesion was resected due to increasing size. The histology of the lesion revealed PPB Type I.

    Incidental findings are inevitable as clinical research and practice transitions from a single gene approach to a genomic approach. A novel deletion of the Fumarate Hydratase (FH) gene was identified in a 22 year old male who underwent a molecular karyotype as part of an autism spectrum disorder research project. This unexpected result implies a predisposition to Hereditary Leiomyomatosis and Renal Cell Cancer (HLRCC), a rare, autosomal dominant condition and has unforeseen implications for him and his family. We review the typical features and management of HLRCC and discuss the challenges that face health professionals, as genetic testing advances and becomes more accessible.

    A sternal cleft is an extremely rare developmental anomaly, which results from failure of fusion of sternal bars which contribute to the formation of the sternum. Most cases are diagnosed in early childhood, where it is associated with serious other midline defects. A sternal cleft is seen as a photopenic area on technetium-99m methylene diphosphonate bone scan and can be confused with other conditions. We report an extremely rare case of isolated upper sternal cleft in a 45-years-old male, found incidentally on '9 9m Tc MDP bone scan. (author)

  2. Pancreatic neuroendocrine tumor - incidental finding during a follow-up CT for primary ovarian carcinoma

    International Nuclear Information System (INIS)

    Ivanova, D.; Balev, B.

    2013-01-01

    Pancreatic neuroendocrine tumors (PNET) are primary, usually we 11-differentiated pancreatic tumors. Their origin is not fully understood, but they are thought to develop from the pluripotent cells in the exocrine part of the pancreas. PNET are a heterogeneous group with different malignant potential. In some of the patients with sporadical forms of PNET there is association with other malignancies such as ovarian cancer, breast cancer, bladder and prostate cancers. We present a case of 50-year-old woman, with incidentally found pancreatic neoplasm, during a follow-up CT for ovarian cancer. Laparotomy and pancreatic biopsy are performed. Histological diagnosis confirms a well- differentiated endocrine tumor of the pancreas. (authors)

    An incidental persistent falcine sinus was detected in an otherwise normal brain on MRI in a 12-year-old girl who underwent imaging after clinical suspicion of acute disseminated encephalomyelitis. The falcine sinus was associated with a hypoplastic posterior third of the superior sagittal sinus and a dominant straight sinus. Generally, atresia or hypoplasia of the straight sinus is associated with a persistent falcine sinus in postnatal life; otherwise, the falcine sinus disappears before birth. We discuss the embryological basis for such an association in this case. (orig.)

    Visual, cortical somatosensory and brainstem auditory evoked potentials were recorded before incidental irradiation of the rhombencephalon during radiotherapy in and around the middle ear, and at 11 weeks and eight months after completion of treatment. No patient experienced neurological symptoms during this period. No consistent changes in evoked potentials were found. The failure to demonstrate subclinical radiation-induced demyelination suggests either that the syndrome of early-delayed radiation rhombencephalopathy occurs in an idiosyncratic manner, or that any subclinical lesions are not detectable by serial evoked potential recordings.

    We present a case of multiple well-differentiated papillary mesotheliomas (WDPM) in the peritoneum found incidentally in a 63-year-old man with urothelial carcinoma of the bladder. When multiple tumors are seen, malignant mesothelioma should be excluded by histopathological examination as this may...... have a similar focal appearance to WDPM. True stromal invasion is by far the most reliable criterion of mesothelial malignancy. In doubtful cases, a conservative diagnostic approach has been recommended. Compared to malignant mesotheliomas, WDPMs are rare and have a relatively indolent clinical course...

    2014-12-01

    Full Text Available The increased use of ultrasound in patients with urological and andrological symptoms has given an higher detection of intra-testicular nodules. Most of these lesions are hypoechoic and their interpretation is often equivocal. Recently, new ultrasound techniques have been developed alongside of B-mode and color-Doppler ultrasound. Although not completely standardized, contrast-enhanced ultrasound (CEUS and tissue elastography (TE, added to traditional ultrasonography, can provide useful information about the correct interpretation of incidentally detected non-palpable testicular nodules. The purpose of this review article is to illustrate these new techniques in the patient management.

    Cardiac imaging using electrocardiogram-gated multi-detector computed tomography (MDCT) permits noninvasive diagnosis of congenital and acquired cardiac pathologies and has thus become increasingly important in the last years. Several studies investigated the incidence and relevance of incidental extracardiac structures within the lungs, mediastinum, chest wall, and abdomen with gated coronary CT. This resulted in the general acceptance of the review of extracardiac structures as a routine component of coronary CT interpretation. On the other hand radiologists tend to neglect pericardial and cardiac pathologies in non-gated chest CT, which is primarily performed for the evaluation of the respiratory system or for tumor staging. Since the introduction of multi-detector spiral CT technology, the incidental detection of cardiac and pericardial findings has become possible using non-gated chest CT. This article reviews the imaging appearances and differential diagnostic considerations of incidental cardiac entities that may be encountered in non-gated chest CT. (orig.)

    The thoracic manifestations of paragangliomas include well-enhancing mediastinal masses, metastatic parenchymal nodules, lymphadenopathy from malignant paragangliomas, and pulmonary edema as a complication of epinephrine-producing paragangliomas. The much less common manifestations include a primary mass in the lung, heart, esophagus and/or trachea. Primary pulmonary paraganglioma was first reported by Heppleston in 1958, and only 19 cases have been reported since then in the English literature. Three of these cases were malignancies with lymph nodes metastases. In the remaining cases, the lesions behaved in a benign manner. The patients are usually female and in their middle age. Most patients are free of symptoms and hypertension, and the tumors are often discovered incidentally on routine chest radiographs.

    Background: Mediastinal tumours are uncommon lesions encountered in clinical practice. There has been a significant increase in the incidence of malignant mediastinal tumours over the past four decades. The presentation varies from asymptomatic lesions detected incidentally on imaging to severe life threatening presentations. Aim and Objectives: The study was conducted to assess the clinical characteristics, types, treatment modalities and outcome of mediastinal masses. Materials and Methods: In this two year prospective study, a total of 35 cases with or without symptoms of mediastinal mass, confirmed by Computed Tomography (CT) imaging were included. The results were expressed as percentages or proportions. Results: Maximum numbers of patients (25.71%) were seen in the 3rd decade and majority (94.3%) was symptomatic at presentation. Malignant lesions (68.57%) were more common than benign (31.43%) and lymphoma was the commonest malignant tumour (50%). Mediastinal widening on chest X-ray was seen in 27 cases (77.14%), pleural effusion and lung mass in 5 cases each (14.29%). On CT imaging and sub-classification, anterior mediastinum was the commonest compartment involved (42.86%). Conclusion: Mediastinal masses are usually symptomatic at presentation. Majority of the masses were malignant lesions and the symptoms of mediastinal obstruction was significantly higher in malignant lesions and anterior mediastinal masses. Lymphoma was the most frequent primary mediastinal mass and thymoma constituted the commonest benign anterior mediastinal tumour. PMID:24701488

  12. Can incidental sighting data be used to elucidate habitat preferences and areas of suitable habitat for a cryptic species?

    The involvement of communities in ecological studies has been shown to augment conservation efforts, especially for cryptic species. However, there is a lack of studies addressing the utility of incidental sighting records from community members in gaining knowledge on habitat preferences and distribution of suitable habitat for these organisms. This study compares preferences of the Lumholtz's tree kangaroo (Dendrolagus lumholtzi; LTK), a cryptic rainforest folivore in northeastern Australia, for various habitat and climatic variables derived from data collected during scientific projects to those derived from incidental sighting records using ArcGIS and Maxent. Incidental sighting records suggest that the species uses a wider range of altitudes, annual rainfalls, annual mean temperatures and vegetation types than predicted by scientific studies. Incidental records also show that the species can persist in areas of lower rainfall during the wettest month and lower minimum temperature during the coldest month. Both data place the species within a comparable range of rainfalls during the driest month, maximum temperatures of the warmest month and soil types. When using identified preferences to assess the extent and distribution of suitable habitat, incidental records predicted more areas of suitable habitat than scientific records with an overlap of up to 91% between them. The present study proves that incidental sighting records can be a valuable part of the study of cryptic species and should be considered complementarily alongside scientific studies to obtain comprehensive ecological information of a species that can assist in its conservation. © 2016 International Society of Zoological Sciences, Institute of Zoology/Chinese Academy of Sciences and John Wiley & Sons Australia, Ltd.

  13. Pictorial essay of radiological features of benign intrathoracic masses

    Syahminan Suut

    2015-01-01

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

  14. Optimising assessment of kidney function when managing localised renal masses.

    2017-08-07

    Increased early and incidental detection, improved surgical techniques and technological advancement mean that the management of renal mass lesions is constantly evolving. The treatment of choice for renal mass lesions has historically been radical nephrectomy. Partial nephrectomy is now recommended for localised renal masses, owing to favourable renal functional outcomes. Ablative renal surgery confers a significant risk of chronic kidney disease. There are few studies assessing long term outcomes of nephrectomy on renal outcomes, and virtually no studies assessing long term outcomes for less invasive therapies such as ablation. Unless a renal mass is clearly benign on imaging, management decisions will be made with an assumption of malignancy. The content of this review applies to both benign and malignant renal mass lesions. We advocate for improved strategies for kidney function assessment and risk stratification, early targeted referral, and regular screening for chronic kidney disease for all patients after surgery.

  17. Peritoneal tuberculosis with pelvic abdominal mass, ascites and elevated CA 125 mimicking advanced ovarian carcinoma: a series of 10 cases.

    2001-01-01

    Ten patients with peritoneal tuberculosis who were operated on for suspected advanced ovarian cancer during a 5-year period were analyzed. These 10 cases constituted 1.4% of the 728 new gynecologic cancer cases diagnosed and treated at our department during the same time period. Data were obtained from patients' files and pathology reports. The mean age of cases was 40.6 +/- 6.1 (median 37; range 18-72). Ascites was present together with ill-defined nodularities or thickening in the Douglas pouch and/or in the adnexal areas on pelvic examination in all patients but three, who presented with well-demarcated adnexal masses of about 5 cm in diameter. All patients had elevated serum CA 125 levels with a median of 331 U/ml, (40-560 U/ml). Ultrasound and abdominopelvic CT examinations revealed omental and mesenteric thickening in addition to ascites in all patients, cystic ovarian masses or ovarian enlargement in five, and peritoneal implants in two. Abdominal paracentesis performed in the six cases in whom the findings were felt to be most inconclusive for the diagnosis of ovarian cancer revealed clear exudative fluid with benign cells. Mycobacteria could not be demonstrated on direct preparations. Tuberculosis was diagnosed at laparotomy in all. Patients received antituberculous therapy and serum CA 125 levels returned to normal within 2 months after the beginning of treatment. This case series demonstrates a high rate of misdiagnosis between advanced ovarian cancer and peritoneal tuberculosis. Whereas abdominal paracentesis is useless in ruling out peritoneal tuberculosis, and serum CA 125 levels are not helpful in the differential diagnosis, the latter marker may be useful in the follow-up of patients.

    In this case report, Mayer-Rokitansky-Kuster-Hauser syndrome with pelvic ectopic kidney and a perirenal cyst with endometrial tissue inside is demonstrated. A 17 year old patient admitted with primary amenorrhea. Pubertal stages were completed. In pelvic ultrasonography; uterus could not be detected, a 6x11 cm sized cystic lesion was seen on the right adnexal area. A centrally located 5.5x9 cm sized ectopic pelvic kidney was detected. Hormones and tumor markers were normal. Laparoscopy was planned. In the laparoscopic observation, uterus and both tubes could not be detected, ovaries were normal. There was a 6x7 cm sized cyst located in the retroperitoneal area, the origin of cyst could not be identified. Laparatomy was considered, retroperitoneal space was entered, an 8x11 sized smooth contoured perirenal cyst adjacent to the pelvic kidney was detected. Cyst was extirpated. The pathology result was reported to include endometrial tissue and hemorrhage inside. (author)

    The Seldinger technique is commonly used cannulate vessels for radiographical procedures. Loss of a guide wire into the circulation is a rare and preventable complication. It is often noticed by chance during routine radiographs. However, there is a lack of reported cases of incidental fin dings of leftover guide wire on a PET scan. An intravascular foreign body should be retrieved as soon as the diagnosis is made, to prevent complications such as embolisation or vascular damage by fractured wires. Interventional radiology is the method of choice for retrieval. We report a rare case of the coincidental finding of a lost guide wire on a PET scan. A 37 year old man presented with psychotic episodes, thigh weakness, weight gain, increased appetite and leg cramps. He was subsequently diagnosed with cushing syndrome secondary to ectopic adrenocorticotropic secretion from a right lung tumour. He subsequently underwent a staging positron emission tomography (PET) scan. The lung tumour had no uptake on PET bit had increased activity uptake on octreotide scanning. These appearances were suggestive of with carcinoid tumour. The PET scan also revealed an incidental finding of a leftover guide wire used during peripheral inserted central catheter (PICC) recently. The wire extended from right atrium to inferior vena cava. It also showed a high uptake in the adrenal glands, indicating hyperplasia, which was most likely due to adrenocorticotropic hormone stimulation. He underwent a percutaneous wire retrieval via the right femoral vein in a cardiac catheterisation laboratory and was transferred to a thoracic surgical unit for lung tumor resection.

    The Seldinger technique is commonly used cannulate vessels for radiographical procedures. Loss of a guide wire into the circulation is a rare and preventable complication. It is often noticed by chance during routine radiographs. However, there is a lack of reported cases of incidental fin dings of leftover guide wire on a PET scan.

    Purpose: To address outcomes in clinically asymptomatic patients in whom the unexpected finding of microscopic perineural invasion is noted at the time of surgery. Methods and Materials: The 35 patients included in this study had skin cancers of the head and neck treated with curative intent between January 1965 and April 1995 at the University of Florida. All patients were without clinical or radiographic evidence of perineural invasion but, at the time of biopsy or surgical excision, had the incidental finding of microscopic perineural invasion. Definitive therapy consisted of radiotherapy alone after lesion biopsy (3 patients) or surgical excision preceded (2 patients) or followed (30 patients) by radiotherapy. All patients had follow-up for at least 1 year, 13 patients (37%) had follow-up for at least 5 years. Results: The 5-year local control rate was 78%. The 5-year local control rate for the few patients treated with radiotherapy alone was statistically similar to that for patients treated with surgery and radiotherapy (100% vs. 77%, p = 0.4). Multivariate analysis for factors affecting local control included sex, histology, age, treatment group, clinical T stage, initial histologic differentiation, and previously untreated vs. recurrent tumors, none of which was found to be significant. Conclusions: Both surgery plus radiotherapy and radiotherapy alone provide a relatively high rate of local control for patients with incidentally discovered perineural invasion secondary to skin cancer

    The purpose was to determine prevalence of enchondromas and atypical cartilaginous tumour/chondrosarcoma grade 1 (ACT/CS1) of the knee on MRI in a large cohort study, namely the Netherlands Epidemiology of Obesity (NEO) study. Participants aged 45 to 65 years were prospectively included, oversampling overweight and obese persons. Within a subgroup of participants, MRI of the right knee was performed and screened for incidental cartilaginous tumours, as defined by their characteristic location and appearance. Forty-nine cartilaginous tumours were observed in 44 out of 1285 participants (estimated population prevalence 2.8 %, 95 % CI 2.0-4.0 %). Mean largest tumour diameter was 12 mm (range 2-31 mm). Eight participants with a tumour larger than 20 mm or a tumour with aggressive features were referred to rule out low-grade chondrosarcoma. One was lost to follow-up, three had histologically proven ACT/CS1 and four had dynamic contrast MRI findings consistent with benign enchondroma. Incidental cartilaginous tumours were relatively common on knee MRI and may be regarded as a normal concurrent finding. However, more tumours than expected were ACT/CS1. Because further examination was performed only when suspicion of chondrosarcoma was high, the actual prevalence might be even higher. (orig.)

    Full Text Available This study examined the effectiveness of L1 and L2 glosses on incidental vocabulary learning in a multimedia environment. The investigation included the effects of additional pictorial cues in L1 and L2 glosses, and how these additions affect vocabulary learning. The analyses of a mixed design repeated measures 2 (L1, L2 X 2 (picture, no picture X 2 (immediate test, delayed test analysis of variance (ANOVA indicated no significant differences between L1 and L2 glosses for definition-supply and recognition tasks and showed significant differences between picture (text-plus-picture and no-picture (text-only glosses for definition-supply test only. The results also revealed significant interaction effects between languages and tests indicating that L1 and L2 groups showed different patterns of vocabulary retention over time. Findings suggest that both L1 and L2 glosses are effective for incidental vocabulary learning, but long-term retention may differ between the two types; and that the effect of additional visual cues on vocabulary learning may rely on the nature of the tasks given.

  6. Distinct error-correcting and incidental learning of location relative to landmarks and boundaries.

    Associative reinforcement provides a powerful explanation of learned behavior. However, an unproven but long-held conjecture holds that spatial learning can occur incidentally rather than by reinforcement. Using a carefully controlled virtual-reality object-location memory task, we formally demonstrate that locations are concurrently learned relative to both local landmarks and local boundaries but that landmark-learning obeys associative reinforcement (showing "overshadowing" and "blocking" or "learned irrelevance"), whereas boundary-learning is incidental, showing neither overshadowing nor blocking nor learned irrelevance. Crucially, both types of learning occur at similar rates and do not reflect differences in levels of performance, cue salience, or instructions. These distinct types of learning likely reflect the distinct neural systems implicated in processing of landmarks and boundaries: the striatum and hippocampus, respectively [Doeller CF, King JA, Burgess N (2008) Proc Natl Acad Sci USA 105:5915-5920]. In turn, our results suggest the use of fundamentally different learning rules by these two systems, potentially explaining their differential roles in procedural and declarative memory more generally. Our results suggest a privileged role for surface geometry in determining spatial context and support the idea of a "geometric module," albeit for location rather than orientation. Finally, the demonstration that reinforcement learning applies selectively to formally equivalent aspects of task-performance supports broader consideration of two-system models in analyses of learning and decision making.

    Diagnosis of cerebral cortical venous thrombosis in patients with postdural puncture headache (PDPH) is usually secondary to changes in headache pattern or cerebral infarctions. Nevertheless, incidental discovery of asymptomatic forms on brain imaging has never been reported before and its management thus remains ill-defined. We describe 2 cases of patients with asymptomatic cortical vein thrombosis in the context of PDPH. In both cases, brain computed tomography (CT) scans showed an isolated cortical vein thrombosis without cerebral damage. Neurological examination revealed the typical orthostatic feature of PDPH, independently of cortical vein thrombosis which was considered as a radiological incidental finding. Clinical and radiological signs resolved after bed rest, oral caffeine, and anticoagulation therapy. Asymptomatic cortical vein thrombosis may be found on radiological exploration, even basic like brain CT scan without contrast, of PDPH. Utility of anticoagulation therapy, which could increase the risk of cerebral hemorrhagic complications in this specific context, has to be assessed.

    The Symbol--Digit Modalities Test (SDMT) is widely used to assess processing speed in MS patients. We developed a computerized version of the SDMT (c-SDMT) that scored participants' performance during subintervals over the course of the usual 90-s time period and also added an incidental learning test (c-ILT) to assess how well participants learned the symbol-digit associations while completing the c-SDMT. Patients with MS (n = 65) achieved lower scores than healthy controls (n = 38) on both the c-SDMT and c-ILT, and the scores on the two tests were correlated. However, no increase in the rate of item completion occurred for either group over the course of the c-SDMT, and the difference between groups was the same during each subinterval. Therefore, it seems implausible that controls completed more items on the c-SDMT because they were more adept at learning the symbol-digit associations as the test ensued. Instead, MS patients' poorer incidental learning performance appears to reflect the greater attentional burden that tasks requiring rapid serial processing of information impose upon them. © The Author 2015.

    The presence of kidney stones has been a relative contraindication for living donation. With the widespread use of more sensitive imaging techniques as part of the routine living donor workup, kidney stones are more frequently detected, and their clinical significance in this setting is largely unknown. Records from 325 potential kidney donors who underwent MRA or CT-angiography were reviewed; 294 proceeded to donation. The prevalence of kidney stones found incidentally during donor evaluation was 7.4% (24 of 325). Sixteen donors with stones proceeded with kidney donation. All incidental calculi were nonobstructing and small (median 2 mm; range 1-9 mm). Eleven recipients were transplanted with allografts containing stones. One recipient developed symptomatic nephrolithasis after transplantation. This recipient was found to have newly formed stones secondary to hyperoxaluria, suggesting a recipient-driven propensity for stone formation. The remaining ten recipients have stable graft function, postoperative ultrasound negative for nephrolithiasis, and no sequelae from stones. No donor developed symptomatic nephrolithiasis following donation. Judicious use of allografts with small stones in donors with normal metabolic studies may be acceptable, and careful follow-up in recipients of such allografts is warranted. © 2011 John Wiley & Sons A/S.

  10. Weight and see: Loading working memory improves incidental identification of irrelevant faces

    Full Text Available Are task-irrelevant stimuli processed to a level enabling individual identification? This question is central both for perceptual processing models and for applied settings (e.g., eyewitness testimony. Lavie’s load theory proposes that working memory actively maintains attentional prioritization of relevant over irrelevant information. Loading working memory thus impairs attentional prioritization, leading to increased processing of task-irrelevant stimuli. Previous research has shown that increased working memory load leads to greater interference effects from response competing distractors. Here we test the novel prediction that increased processing of irrelevant stimuli under high working memory load should lead to a greater likelihood of incidental identification of entirely irrelevant stimuli. To test this, we asked participants to perform a word-categorization task while ignoring task-irrelevant images. The categorization task was performed during the retention interval of a working memory task with either low or high load (defined by memory set size. Following the final experimental trial, a surprise question assessed incidental identification of the irrelevant image. Loading working memory was found to improve identification of task-irrelevant faces, but not of building stimuli (shown in a separate experiment to be less distracting. These findings suggest that working memory plays a critical role in determining whether distracting stimuli will be subsequently identified.

    We examined whether cats could retrieve and utilize incidentally encoded information from a single past event in a simple food-exploration task previously used for dogs (Fujita et al., 2012). In Experiment 1, cats were led to four open, baited containers and allowed to eat from two of them (Exposure phase). After a 15-min delay during which the cats were absent and all containers were replaced with empty ones, the cats were unexpectedly returned to the room and allowed to explore the containers (Test phase). Although the cats' first choice of container to visit was random, they explored containers from which they had not previously eaten for longer than those from which they did previously eat. In the Exposure phase of Experiment 2, two containers held food, one held a nonedible object, and the fourth was empty. Cats were allowed to eat from one of them. In the post-delay Test phase, the cats first visited the remaining baited-uneaten container significantly more often than chance and they spent more time exploring this container. Because the cats' behavior in the Test phase cannot be explained by association of the container with a pleasant experience (eating), the results suggest that cats retrieved and utilized "what" and "where" information from an incidentally encoded memory from a single experience.

    Recent advances in neuroimaging techniques have resulted in more frequent detection of unruptured intracranial aneurysms. Regardless of the method employed, most interventions to treat lesions have low morbidity and mortality rates. Recently, some studies have suggested that changes in cognitive status are one complication of microsurgical treatments. However, no study to date has performed any behavioral analysis. Moreover, cognitive assessment beyond 12 months after surgical intervention is missing. The current study sought to evaluate the long-term impact of clipping on the behavioral and cognitive functions of patients with unruptured intracranial aneurysms. A within-subjects prospective clinical trial was performed to evaluate 40 patients who underwent microsurgical clipping for incidental unruptured intracranial aneurysms. The participants underwent a full neuropsychological evaluation during the preoperative period, at 3 months after surgery and at 3 years after surgery. Paired Student's t tests and an ANOVA, followed by a Bonferroni post hoc test, were used to examine group differences. The cognitive and behavioral test performance of the patients did not deteriorate during either the short or the long term following intervention. Moreover, the patients' clinical and demographic characteristics did not predict behavioral or cognitive changes, and neither the surgical approach nor the topography, multiplicity, or size of the aneurysms affected the results. In either the short or the long term following clipping for patients with incidental unruptured intracranial aneurysms, behavioral and cognitive functions had no significant change from baseline. The intervention demonstrated high efficacy and was associated with a low morbidity rate.

    Full Text Available Coastal dolphins are regarded as indicators of changes in coastal marine ecosystem health that could impact humans utilizing the marine environment for food or recreation. Necropsy and histology examinations were performed on 35 Indian Ocean bottlenose dolphins (Tursiops aduncus and five Indo-Pacific humpback dolphins (Sousa plumbea incidentally caught in shark nets off the KwaZulu-Natal coast, South Africa, between 2010 and 2012. Parasitic lesions included pneumonia (85%, abdominal and thoracic serositis (75%, gastroenteritis (70%, hepatitis (62%, and endometritis (42%. Parasitic species identified were Halocercus sp. (lung, Crassicauda sp. (skeletal muscle and Xenobalanus globicipitis (skin. Additional findings included bronchiolar epithelial mineralisation (83%, splenic filamentous tags (45%, non-suppurative meningoencephalitis (39%, and myocardial fibrosis (26%. No immunohistochemically positive reaction was present in lesions suggestive of dolphin morbillivirus, Toxoplasma gondii and Brucella spp. The first confirmed cases of lobomycosis and sarcocystosis in South African dolphins were documented. Most lesions were mild, and all animals were considered to be in good nutritional condition, based on blubber thickness and muscle mass. Apparent temporal changes in parasitic disease prevalence may indicate a change in the host/parasite interface. This study provided valuable baseline information on conditions affecting coastal dolphin populations in South Africa and, to our knowledge, constitutes the first reported systematic health assessment in incidentally caught dolphins in the Southern Hemisphere. Further research on temporal disease trends as well as disease pathophysiology and anthropogenic factors affecting these populations is needed.
