3 Background: The current ACR practice guidelines discourage use of MRI for work-up of suspicious findings in mammography (Mx) and ultrasound (US). We investigated whether additional breast MRI assessment of suspicious Mx and U.S. findings could improve PPV and thus possibly help reduce the number of biopsies for false positive findings in Mx or U.S. Methods: Between 06/2010 and 04/2012, a total 2,754 patients underwent DCE breast MRI. Of these, 277 underwent MRI for further work-up of suspicious findings made in Mx (n=173, 57 patients with mass lesions, 33 with asymmetries, 12 with architectural distortions, and 71 with suspicious calcifications) or U.S. (n=104, 74 with masses, 30 with miscellaneous U.S. findings such as suspected intraductal pathology, focal acoustic shadowing or architectural distortions) . All lesions categorized as MR-BIRADS 4 and 5 underwent biopsy, lesions categorized as MR-BIRADS 1 or 2 did not proceed to biopsy, except for selected women with mammographic calcifications suggestive of DCIS. Lesions categorized as MR-BIRADS 3 underwent additional short term follow-up by MRI, US and/or Mx. All women who did not undergo biopsy (MR-BIRADS 1-3) underwent long term follow-up for so far 12-24 months. Results: For suspicious lesions in mammography, MRI increased PPV from 19.3% (11/57) to 92.3% (12/13) for masses, from 3% (1/33) to 33.3% (1/3) for asymmetries, from 8.3% (1/12) to 25% (1/4) for architectural distortions and from 21.1% (15/71) to 62.5% (15/24) for calcifications. For suspicious lesions in ultrasound, MRI increased PPV from 13.5% (10/74) to 71.4% (10/14) for masses and from 3.3% (1/30) to 50% (1/2) for non-mass U.S. findings. In 4/277 patients, MRI showed additional suspicious findings, requiring MR-guided biopsy, one of which was histologically proven malignant. So far, none of the patients who, because of an MR-BIRADS 1-3, did not undergo biopsy has been diagnosed with invasive cancer or DCIS or with progressive conventional imaging findings necessitating secondary biopsy. Conclusions: MRI improves PPV for both suspicious Mx and U.S. findings, especially mass lesions. In experienced hands, careful use of MRI can help avoid biopsies for false positive diagnoses made in Mx and U.S.

Objective: The aim of this study was to compare, in order to increase our ability to detect bladder cancer, the predictive power of narrow band imaging (NBI) versus white light cystoscopy (WL). The secondary objective was to evaluate how the preoperative use of NBI cystoscopy can increase the ability to detect bladder lesions in terms of status, multi-focality and dimensions. Materials and methods: Between June 2010 and April 2012, 797 consecutive patients, 423 male and 374 female, affected by suspected bladder cancer lesions, underwent to WL plus NBI cystoscopy and subsequently to WL Bipolar Gyrus PK (Olympus, Tokyo, Japan) transurethral resection of bladder tumour (WL-TURBT). The average follow-up was 24 (16-38) months. Mean age was 67.7 yrs. (range 46-88). All the patients underwent by same surgeon to WL resection (WL-TURBT) of the previously identified lesions by same surgeon. All the removed tissue was sent separately for histological evaluation after mapping the areas of resection on a topographic sheet. Results: In our study we considered 797 patients that matched our inclusion criteria. Through the use of WL cystoscopy, we identified 603 patients (75.53%) with suspicious lesions, instead, with the use of light NBI, we found 786 patients with suspicious lesions (98.49%).The use of NBI cystoscopy increases by approximately 30% the specific ability to detect lesions not otherwise visible with WL cystoscopy (OR 21.9 and RR 1.30), in particular for patients with lesions size < 3 cm (OR 24.00; RR 1.40), unifocal (OR: 22.28; RR 1.47) and recurrent (OR 58.4; RR 1.34). Pathology demonstrated the presence of cancer in 512 (64.2%) patients, of whom 412 (51.8%) were visible both with WL cystoscopy and NBI cystoscopy. In our experience, only 11 (1.38%) lesions were only positive at WL cystoscopy (negative at NBI cystoscopy) thus 501 (62.8%, OR 10.13; RR 1.21) patients showed bladder oncological lesions positive at NBI cystoscopy. In these patients, the use the NBI Cystoscopy has better highlighted a recurrence (p < 0.005; OR 22.8, RR 1.23; 95% CI-1.13 to 0.24) or a lesion < 3 cm (p < 0.05; OR 11.4 , RR 1.30; 95% CI-0.18 to 0.29) or a unifocal lesion (p < 0.005; OR 10.38, RR 1.34, CI 0.18 to 0.30). Conclusions: The use of NBI cystoscopy, significantly increases by approximately 30% our predictive power to identify neoplastic lesions, especially unifocal or < 3 cm or recurrent lesions. Following WLTURBT, stage, dimension and focaliity are statistically significant determinants (p < 0.001) of the bladder oncological lesions detected by NBI cystoscopy rather than by WL cystoscopy.

In this study quantitative techniques have been applied to smears collected from the buccal mucosa and floor of the mouth. The results display an encouraging success rate for identifying premalignant and malignant lesions. ‘Intrapatient’ normal smears provide a satisfactory control for comparison with pathological smears. Early results indicate that quantitative cytology could be of great value for monitoring and follow-up of suspicious lesions and provide an excellent additional diagnostic test for detecting early oral malignancy.

Introduction: Breast Imaging, Reporting and Data System (BI-RADS) is an effective tool for management of patients with breast pathologies. While the BI-RADS 1 (negative) and BI- RADS 2 (benign) categories patients are advised for routine mammography screening. BI-RADS 4 (suspicious abnormality) and BI-RADS 5 (highly suggestive of malignancy) categories patients are recommended for tissue diagnosis, BI-RADS 3 category patients are managed with follow-up examinations. But upto 2% of BI-RADS 3 lesions are proved to be malignant on follow-up examinations and tissue diagnosis. Aim: To evaluate the efficacy of spectral Doppler indices in predicting malignancy in BI-RADS 3 category breast lesions. Materials and Methods: A prospective cohort study was conducted in the Department of Radiology, Katuri Medical College, Guntur, Andra Pradesh, India from July 2019 to February 2021. Study was conducted on 292 BI-RADS 3 lesions from 257 patients to evaluate the efficacy of spectral Doppler indices in differentiating malignant BI-RADS 3 lesions from benign ones. All the breast masses were evaluated with spectral doppler and the resistive and pulsatility indices were compared with histopathology findings of the suspicious lesions detected in follow-up examinations. Statistical analysis was performed using Statistical Package for the Social Sciences (SPSS) 2017 version 25, and the quantitative data was expressed in mean and standard deviation. Results: The patients recruited in the study were in age range of 27-80 years, and the mean age of the patients was 46±15 years (mean±SD). Follow-up examinations and tissue diagnosis of suspicious lesions revealed 8 out of 292 BI-RADS breast masses to be malignant. On spectral Doppler analysis, high resistivity and pulsatility indices are predictive of malignancy. A resistive index of more than 0.6 as a sign of malignancy proved to have a sensitivity of 87.5% and specificity of 85.5% and more than 0.8 as a sign of malignancy has a sensitivity of 25% and specificity of 95%. A pulsatility index of more than 0.9 as a sign of malignancy has a sensitivity of 87.5% and specificity of 87% and more than 1.6 as a sign of malignancy has a sensitivity of 37.5% and specificity of 96%. Conclusion: Spectral doppler is reliable in the prediction of malignancy of BI-RADS 3 breast masses.

AbstractNeurobiology-based interventions for mental diseases and searches for useful biomarkers of treatment response have largely failed. Clinical trials should assess interventions related to environmental and social stressors, with long-term follow-up; social rather than biological endpoints; personalized outcomes; and suitable cluster, adaptive, and n-of-1 designs. Labor, education, financial, and other social/political decisions should be evaluated for their impacts on mental disease.

AbstractA long-term photographic search programme for minor planets was begun at the Kleť Observatory at the end of seventies using a 0.63-m Maksutov telescope, but with insufficient respect for long-arc follow-up astrometry. More than two thousand provisional designations were given to new Kleť discoveries. Since 1993 targeted follow-up astrometry of Kleť candidates has been performed with a 0.57-m reflector equipped with a CCD camera, and reliable orbits for many previous Kleť discoveries have been determined. The photographic programme results in more than 350 numbered minor planets credited to Kleť, one of the world's most prolific discovery sites. Nearly 50 per cent of them were numbered as a consequence of CCD follow-up observations since 1994.This brief summary describes the results of this Kleť photographic minor planet survey between 1977 and 1996. The majority of the Kleť photographic discoveries are main belt asteroids, but two Amor type asteroids and one Trojan have been found.

During a project in which regenerative changes were studied in autotransplanted canine kidneys, intranuclear crystals were seen in a small number of tubular epithelial cells. These crystalline structures were seen in the control specimens and also in regenerating specimens; the main differences being in size and number of them. The control specimens showed a few tubular epithelial cell nuclei almost completely occupied by large crystals that were not membrane bound. Subsequent follow-up biopsies of the same kidneys contained similar intranuclear crystals but of a much smaller size. Some of these nuclei contained several small crystals. The small crystals occurred at one week following transplantation and were seen even four weeks following transplantation. As time passed, the small crystals appeared to fuse to form larger crystals.

Scanning microscopy was used to study the surface of human gallstones and the surface of fractures. The specimens were obtained by operation, washed with water, dried at room temperature and shadowcasted with carbon and aluminum. Most of the specimens belong to patients from a series of X-ray follow-up study, examined during the last twenty years. So it was possible to evaluate approximately the age of these gallstones and to get information on the intensity of growing and solving.Cholesterol, a group of bile pigment substances and different salts of calcium, are the main components of human gallstones. By X-ray diffraction technique, infra-red spectroscopy and by chemical analysis it was demonstrated that all three components can be found in any gallstone. In the presence of water cholesterol crystallizes in pane-like plates of the triclinic crystal system.
