Abstract
Abstract
Background
Most of the literature on conflict of interest (COI) has not focused on the role of academic editors and their possible COIs, although academic editors often hold senior faculty positions at universities, which might be considered a COI if this influences towards a more favourable processing to articles submitted by institutional colleagues. The current study aims to assess whether academic editor affiliation, a potential COI, can influence academic institution ranking as top contributor in the biomedical field.
Methods
We conducted a cross-sectional analysis extracting publicly available data from the 2019 Clarivate InCites Journal Citation Reports for journals in the “Medicine, General & Internal” category and from each journal website. We constructed the following study outcomes: i) being a top 5 academic contributor for the peer-review journal of interest (yes/no), ii) being a top 10 academic contributor for the peer-review journal of interest (yes/no), and iii) ranking position as top 50 academic contributor for the peer-review journal of interest. Mixed-effect linear and logistic regression models were employed, as appropriate.
Results
We included 114 journals in our analysis, 49% were open-access only. Sharing same affiliation of any of the editorial board members was associated with a 6.7 and 5.6 greater likelihood of being top 5 and top 10 contributors, respectively (95%CI 5.07-8.73 and 4.34-7.22). Similarly, sharing same affiliation was associated with being 12.1 places higher as top contributor (95%CI 10.35-13.81). When considering the editor in chief affiliation solely, association was even stronger.
Conclusions
We found that academic editors sharing the same institutional affiliation with authors was strongly associated with the likelihood of that institution of being a top contributor. Shared institutional affiliations between editors and authors should be clearly stated as part of an open and transparent peer-review process.
Key messages
• Editors sharing same affiliation with authors was strongly associated with the likelihood for the institution the editor was affiliated with of being top contributor for academic medical journals.
• Shared institutional affiliations between editors and authors should be clearly stated as part of an open and transparent peer-review process.

Abstract
OBJECTIVE Anaplastic lymphoma kinase (ALK) gene has been demonstrated to be rearranged, mutated or amplified in several haematological and solid tumors. Moreover, the use of ALK inhibitors has recently revolutionized the treatment of ALK-rearranged patients affected by non-small cell lung carcinoma. Herein we review the genetic alterations of ALK in melanocytic neoplasms described in literature, focusing on their potential diagnostic and predictive role. MATERIALS AND METHODS The Authors reviewed the pertinent literature through research on PubMed server was performed typing the terms "ALK", "Anaplastic lymphoma kinase", "ALKATI", "Melanoma", "Spitz", "Spitzoid". RESULTS ALK translocations were demonstrated in melanocytic neoplasms, particularly in acral melanoma and spitzoid tumors. ALKATI was described in primary and metastatic melanoma, indicating its early occurrence in oncogenesis, with varying immunohistochemical expression of the protein. CONCLUSIONS The identification of the specific type of ALK mutations could be interesting for planning biologic therapy of melanoma patients. Further studies are needed to evaluate the possibility to introduce an ALK-targeted therapy in patients affected by malignant melanoma.

Abstract
Alopecia areata (AA) is a complex immune-mediated disorder, which is difficult to treat. The available treatment options seem to have limited benefit, help only some patients and have a high relapse rate. We evaluated a new therapeutic option for moderate to severe AA based on the combination of photodynamic therapy (PDT) with 5-aminolaevulinic acid (ALA) and microneedling (MN). In total, 14 patients were enrolled, and these were randomly divided into 3 groups: Group A (MN alone; n = 9), Group B (ALA-PDT alone; n = 15) and Group C (combination of MN and ALA-PDT; n = 17). All patients were treated once every 3 weeks for a total of six treatments. The best clinical outcome was achieved in Group C, with complete hair regrowth observed in three patients, and an improvement of ≥ 50% and < 50% of the treated areas obtained in seven and six patients, respectively. Our report suggests that combination of ALA-PDT with MN could be an additional therapeutic option in moderate to severe AA, as MN allows better skin penetration of ALA and subsequent indirect immunosuppression.

Abstract
Abstract
Background
In Rare diseases patients. difficult in diagnosis can produce inappropriate pathways of care. A correct diagnosis took almost 5 years in Europe and 7.3-7.6 y in US. The directive 2011/24/EU provides a legal regulatory asset for the European Reference Networks (ERNs). ERNs are designed to connect health care providers and centers of expertise for gaining appropriate pathways of high-quality care and to support sponsorship in order to make healthcare closer to the patients. Federico II University actually has 9 confirmed ERNs.
Methods
We connected the patient related activities inside the ERNs and we planned a project-based network that creates harmonization of diagnostic tools and widespread diffusion of screening activity able to drive diagnostic enrichment. The Hospital Chief Office together with the Public Health Department acts as “Knowledge brokers” (KB) defined as connectors who may crisscross the hierarchical boundaries. We scheduled interventions into the ERNs and future improvements. Interventions areas have been represented in a conceptual map.
Results
Brokers into the network are attended to allow better merged innovation rate and sharing data. Improvements could be directed toward: 1) sharing data and communication, 2) diagnostic enrichment 3) hospital services networking into the path. Including this model in the regional pathways may build a common platform to support appropriate care in disease-endemic regions.
The designed model finally aimed at define how humanization and networking of care can be measured as gain in efficiency along the overall path.
Conclusions
Network potential may overload a simply specific hub focused approach. The “criss cross” knowledge brokering (could be a strategy able to support clinical and diagnostic activities. To proceed over, in orphan disease handling, we may progress from approaches centered on florid cases toward a balanced screening design, able to guarantee a diagnostic enrichment for a rare condition.
Key messages
Implicit and formal Networking cam help rare disease handling. Sharing data and diagnostic enrichment are the main issues.

Abstract
BACKGROUND The World Health Organization's Action Framework for tuberculosis elimination in low-tuberculosis incidence countries includes the screening for active and latent tuberculosis in selected high-risk groups, including health care workers. In this context, medical and health profession students, exposed to nosocomial tuberculosis transmission during training and clinical rotations, are target populations for tuberculosis screening. No updated data are available on tuberculosis screening practice and knowledge of medical and health profession students in Italy. METHODS Within the activities Italian Study Group on Hospital Hygiene of the Italian Society of Hygiene, Preventive Medicine and Public Health, we carried out a multicentre cross-sectional study to assess knowledge, attitude and practices on tuberculosis prevention and control among Medical, Dentistry, Nursing and other health professions' students. Students were enrolled in the study on a voluntary basis and were administered a previously piloted structured questionnaire. Logistic regression models were applied to explore knowledge on tuberculosis prevention by selected socio-demographic variables and University-based tuberculosis prevention practice. RESULTS Students of seventeen Universities across Italy participated in the study, and 58.2% of them received compulsory tuberculin skin test either at enrollment or while attending clinical practice. A total of 5,209 students filled the questionnaire. 37.7% were medicine and dentistry students (Group 1), 44.9% were nursing students (Group 2) and 17.4% were other health professions' students (Group 3). Age and gender had different distributions by groups, as well as knowledge and practice on tuberculin skin test. 84.4% of the study population (95% CI = 83.3-85.3) was aware of the existence of the tuberculin skin test, 74.4% (95% CI = 73.2-75.6) knew what is the first-level screening test for latent tuberculosis and only 22.5% (95% CI = 21.4-23.6) knew how to proceed after a positive tuberculin skin test result. Overall, knowledge on tuberculosis prevention was higher in Group 2 and lower Group 3, as compared to Group 1. CONCLUSION In Italy, the knowledge on tuberculosis screening among University students is generally good. To reduce some of the criticalities found among the different study courses, it would be appropriate to harmonize both the regulations on tuberculosis screening practices for admission to University courses, and the educational activities on the topic of tuberculosis, to be extended to all workers involved in health care setting.

Abstract
Abstract
Background
Endothelial cells arise from endothelial progenitor cells (EPCs), which reside in bone marrow vascular niches, and are classified according to specific functional differences. Oxidative stress and inflammation lead to endothelial dysfunction that is a critical event in the initiation and progression of atherosclerotic plaques. Patients with chronic renal failure frequently show endothelial dysfunction and are at a greatly increased risk of developing atherosclerosis. Owing to their ability to partially restore vascular damage, both the number and functional changes in EPCs may be considered as useful prognostic biomarkers of cardiovascular events in hemodialysis (HD) patients.
Purpose
This study investigated EPC features and several biomarkers of systemic vascular inflammation and carotid atherogenesis in hemodialysis (HD) patients.
Methods
We studied 104 HD patients (males=55 and females 49, mean age: 51±12 years) and 40 healthy controls (males=20/females=20; mean age: 52±11 years). Isolated EPCs were cultured in the fibronectin-covered culture dishes and counted. EPC markers were studied by flow cytometry (FACS) by using anti-CD34, anti-CD133 and anti-vascular endothelial growth factor receptor 2 (VEGFR-2) antibodies. Serum levels of intercellular cell adhesion molecule (ICAM), vascular cell adhesion molecule (VCAM), IL-6, TNF-α, and asymmetric dimethyl-arginine (ADMA) were measured by ELISA method. Carotid intima-media thickness (CIMT) and ratio (CIMR) were also evaluated.
Results
In our experimental conditions, EPC number was decreased in HD patients when compared to controls (p<0.01). Expression of CD34 was significantly lower in the HD group (p<0.01). Interestingly, EPCs were significantly inversely correlated with serum TNF-α levels in HD patients (r=−0.388, p<0.01) but not in the control group (r=−0.133, p=NS). Furthermore, there was an inverse association between VEGFR-2 positive cells and serum TNF α levels (r=−0.401, p=0.002) in HD patients. In HD patients, there was a positive correlation between ICAM levels with CIMT (r=0.405, p=0.03) and CIMR was positively correlated with VCAM levels (r=0.377, p=0.01) and ADMA (r=0.233, p<0.05).
Conclusions
Our study shows that EPC number was decreased in HD patients and it was associated with systemic inflammation. TNF-α could activate inhibitory actions on EPC in HD patients. A significant relationship was present between ICAM/VCAM and carotid atherosclerosis, while this was not evident with EPC number. These pathogenic mechanisms can contribute to the high incidence of cardiovascular diseases in HD patients. However, further larger studies should investigate this working hypothesis.

Abstract
According to the "Developmental Origins of Health and Disease" (DOHaD) concept, the early-life environment is a critical period for fetal programming. Given the epidemiological evidence that air pollution exposure during pregnancy adversely affects newborn outcomes such as birth weight and preterm birth, there is a need to pay attention to underlying modes of action to better understand not only these air pollution-induced early health effects but also its later-life consequences. In this review, we give an overview of air pollution-induced placental molecular alterations observed in the ENVIRONAGE birth cohort and evaluate the existing evidence. In general, we showed that prenatal exposure to air pollution is associated with nitrosative stress and epigenetic alterations in the placenta. Adversely affected CpG targets were involved in cellular processes including DNA repair, circadian rhythm, and energy metabolism. For miRNA expression, specific air pollution exposure windows were associated with altered miR-20a, miR-21, miR-146a, and miR-222 expression. Early-life aging markers including telomere length and mitochondrial DNA content are associated with air pollution exposure during pregnancy. Previously, we proposed the air pollution-induced telomere-mitochondrial aging hypothesis with a direct link between telomeres and mitochondria. Here, we extend this view with a potential co-interaction of different biological mechanisms on the level of placental oxidative stress, epigenetics, aging, and energy metabolism. Investigating the placenta is an opportunity for future research as it may help to understand the fundamental biology underpinning the DOHaD concept through the interactions between the underlying modes of action, prenatal environment, and disease risk in later life. To prevent lasting consequences from early-life exposures of air pollution, policy makers should get a basic understanding of biomolecular consequences and transgenerational risks.

Abstract
BACKGROUND Pink skin tumours are difficult to differentiate, clinically and dermoscopically. In previous studies, mainly focused on pigmented lesions, pattern analysis provided the best sensitivity and specificity values, as compared to other algorithms. These findings suggest that the global dermoscopic appearance, based on the evaluation of prevalent features, could represent a valuable and practical approach even when dealing with pink lesions. OBJECTIVE In this study, we aimed to evaluate the diagnostic accuracy of a new dermoscopic approach for pink tumours based on the prevalent criterion, as compared to a standard diagnostic method (Menzies algorithm). METHODS The databases of two referral centres were retrospectively evaluated to retrieve dermoscopic images of amelanotic/hypomelanotic skin lesions. Two experts in dermoscopy, blinded for the final diagnosis and for clinical and demographic information, evaluated separately dermoscopic pictures of 1000 lesions according to the Menzies score and to the prevalent criterion method. RESULTS According to the high sensitivity model of the Menzies score, 129 (12.9%) lesions were considered as non-suspicious (of which 16 were false negative) and 871 (87.1%) as suspicious (of which 212 were false positive), with 97.6% sensitivity and 34.8% specificity. According to the high specificity model, 370 (37%) lesions were evaluated as non-suspicious (of which 105 were false negative) and 630 (63%) as suspicious (of which 60 were false positive), with 84.4% sensitivity and 81.5% specificity. Concerning the prevalent criterion method, 316 (31.6%) lesions were evaluated as non-suspicious (of which 46 were false negative) and 684 (68.4) as suspicious (of which 55 were false positive), with 93.2% sensitivity and 83.1% specificity. CONCLUSIONS This study demonstrated that focusing on the prevalent dermoscopic features could allow to detect malignant pink tumours with similar sensitivity but higher specificity than using the conventional Menzies scoring system.

Abstract
INTRODUCTION Peri-implant breast seroma is a late clinical presentation of reconstructive surgery or augmentation mammoplasty with breast implants. Pre-operative cytological evaluation of the peri-implant breast seroma is a common clinical approach, showing mainly an inflammatory reaction or more rarely a breast implant-associated anaplastic large cell lymphoma. Herein, we reported the role of cytology in the evaluation of peri-implant breast seroma and its critical pre-operative implications. METHODS Eight cases of peri-implant breast seroma from files at Luigi Vanvitelli University were identified between January and December 2017. In all cases, seroma was aspirated; cytospins were performed and stained by Papanicolaou stain; finally, in all cases, a cell block was obtained for immunocytochemical evaluation and, in one case, for FISH to detect ALK1-gene translocation. RESULTS The median age of patients was 48 years and the mean time between the implant placement and the occurrence of peri-implant breast seroma was 18 months. Microscopic examination showed breast implant-associated anaplastic large cell lymphoma in one case, aspecific inflammatory reaction in six cases and silicon-associated reaction in one case. CONCLUSIONS Peri-implant breast seroma may be caused by several pathological conditions with different clinical behaviour. A proper cytological approach to peri-implant breast seroma allows a correct differential diagnosis between inflammatory conditions and breast implant-associated anaplastic large cell lymphoma and an appropriate management of the patient.

Abstract
Spitzoid lesions represent a challenging and controversial group of tumours, in terms of clinical recognition, biological behaviour and management strategies. Although Spitz naevi are considered benign tumours, their clinical and dermoscopic morphological overlap with spitzoid melanoma renders the management of spitzoid lesions particularly difficult. The controversy deepens because of the existence of tumours that cannot be safely histopathologically diagnosed as naevi or melanomas (atypical Spitz tumours). The dual objective of the present study was to provide an updated classification on dermoscopy of Spitz naevi, and management recommendations of spitzoid-looking lesions based on a consensus among experts in the field. After a detailed search of the literature for eligible studies, a data synthesis was performed from 15 studies on dermoscopy of Spitz naevi. Dermoscopically, Spitz naevi are typified by three main patterns: starburst pattern (51%), a pattern of regularly distributed dotted vessels (19%) and globular pattern with reticular depigmentation (17%). A consensus-based algorithm for the management of spitzoid lesions is proposed. According to it, dermoscopically asymmetric lesions with spitzoid features (both flat/raised and nodular) should be excised to rule out melanoma. Dermoscopically symmetric spitzoid nodules should also be excised or closely monitored, irrespective of age, to rule out atypical Spitz tumours. Dermoscopically symmetric, flat spitzoid lesions should be managed according to the age of the patient. Finally, the histopathological diagnosis of atypical Spitz tumour should warrant wide excision but not a sentinel lymph-node biopsy.

Abstract
The history of medicine is replete with examples of debunked myths, and in daily clinical dermatological practice, we must still counter many misconceptions regarding pigmented lesions, both with patients and other medical practitioners. Debunking myths and attempting to explain the reasons for these erroneous beliefs are the purposes of this review. The literature review has been partially guided by the results obtained from an online questionnaire conducted on an Italian website (www.vediamocichiara.it) from February 15, 2015 to March 15, 2015. The remaining discussed were selected on the basis of the existing literature and our personal experience. In order to explore these misconceptions, the following are the seven most salient questions that require investigation: (i) Is it dangerous to excise moles?; (ii) Is it dangerous to traumatize moles?; (iii) Are plantar moles worrisome?; (iv) Is it necessary to selectively apply sunscreen to moles?; (v) Is it inadvisable to partially biopsy a melanoma?; (vi) Do moles turn into melanoma?; and (vii) Is it necessary to perform sentinel lymph node biopsy for thin melanomas and for atypical Spitz naevi? Myths are ubiquitous, being prevalent in dermatological practice, with many of them concerning pigmented skin lesions. By encouraging critical analysis by patients and medical practitioners, the birth and perpetuation of myths can potentially be minimized, for the ultimate benefit of patients. This requires a scientific approach to be rigorously applied to dermatology, with critical questioning of unsubstantiated hypotheses including those emanating from the mass media as well as from respected sources.

Abstract
Skin cancer is a major health problem because of its high incidence in white populations, as well as its related potential morbidity and mortality. Dermoscopy is a noninvasive tool that allows the identification of specific morphological features in different skin tumors, improving significantly the early diagnosis of melanoma and non-melanoma skin cancer (NMSC). This tool has also gained increased interest in the management of NMSC therapy and in the post-treatment follow-up. In this article, we provide a review of the dermoscopic patterns and criteria for the diagnosis of melanoma and NMSC described until now in the literature.

Abstract
BACKGROUND As a result of several clinical reports addressing coincidence or coprevalence of atopy and autoimmune disease such as multiple sclerosis and type I diabetes mellitus, there has been considerable interest in defining the relationship between the expression of allergic and autoimmune disease in populations of patients. Although thyroid autoimmunity has been regularly associated with chronic urticaria in children, the cofrequency of thyroid autoimmunity and atopic dermatitis has not yet been investigated. The aim of the study was to describe our experience with children affected by atopic dermatitis and associated thyroid autoimmunity. METHODS From January 2010 to December 2012, 147 children affected by atopic dermatitis were consecutively referred to the Pediatric Clinic of the Pediatric Department at the Second University of Naples. Seventy healthy children of comparable ages, unaffected by atopic dermatitis, atopy or thyroid disease, served as a control group. RESULTS On the basis of skin prick test results we selected 54 IgE-mediated (36.7%) and 93 non-IgE-mediated AD (63.3%) children. Fourteen of 147 patients (9.52%) showed increased levels of antithyroid antibodies. CONCLUSIONS Our results therefore suggest that atopy, especially food allergy, and autoimmunity are two potential outcomes of dysregulated immunity.

Abstract
An ultrawide tuning range from 1160 to 1620 nm for LiInSiO(4) and from 1150 to 1600 nm for LiInGeO(4) crystals has been demonstrated. This is the widest bandwidth and the most near-infrared shifted wavelength range for laser operation ever demonstrated for the Cr(3+) ion. For what is believed to be the first time tunable laser operation was achieved for both the 1.33 and 1.55 microm telecommunication windows from a single optical center.

Abstract
The backscattering of circularly polarized light at normal incidence to a half-space of scattering particles is studied using the Electric Field Monte Carlo (EMC) method. The spatial distribution of the backscattered light intensity is examined for both the time-resolved and continuous wave cases for large particles with anisotropy factor, g, in the range 0.8 to 0.97. For the time-resolved case, the backscattered light with the same helicity as that of the incident beam (co-polarized) is found to form a ring centered on the point of incidence. The ring expands and simultaneously grows weak as time increases. The intensity of backscattered light with helicity opposite to that of the incident beam (cross-polarized) is found to exhibit a ring behavior for g >/= 0.85, with significant backscattering at the point of incidence. For the continuous-wave case no such ring pattern is observed in backscattered light for either helicity. The present EMC study suggests that the ring behavior can only be observed in the time domain, in contrast to previous studies of light backscattered from forward scattering media based on the scalar time-independent Fokker-Planck approximation to the radiative transfer equation. The time-dependent ring structure of backscattered light may have potential use in subsurface imaging applications.

Abstract
We studied deletion and monosomy of chromosome 7 in 150 patients with myeloproliferative diseases. We found 8/150 patients with monosomy 7 by cytogenetics and 4/150 with deletions of the long arm of chromosome 7 by restriction fragment length polymorphism (RFLP) analysis performed with Southern and polymerase chain reaction. To overcome limitation of RFLP analysis, we restricted loss of heterozygosity study with microsatellites to 45 patients, observing deletion 7q31.1 in 7/45 patients. In all patients with molecular alterations the deletion was observed only in myeloid cells, while the monosomy was detected in both myeloid precursor and lymphocytes. This finding suggests a CD34-totipotent stem cell origin for the monosomy and a colony forming unit - granulocyte, erythrocyte, monocyte, megakaryocytes (CFU-GEMM) stem cell origin for the deletions.

Abstract
Deep subsurface imaging in tissues is demonstrated by employing both spectral and polarization discrimination of the backscattered photons. This technique provides enhancement in the visibility of subsurface structures via processing of the depolarized images obtained using polarized illumination at different wavelengths. The experimental results demonstrate detection and imaging of a high-scattering object located up to 1.5-cm beneath the surface of a host chicken tissue used as the model medium.

Abstract
In a group of subjects (n = 35) with nonvalvular atrial fibrillation (AF) subdivided according to the presence (n = 16) or absence (n = 19) of left atrial spontaneous echocontrast (SEC), demonstrated using transthoracic and transesophageal echocardiography, we evaluated the principal haemorheological determinants: whole-blood viscosity, plasma and serum viscosity, haematocrit, whole-blood filtration (VBC) and mean erythrocyte aggregation (MEA). From the obtained data it was evident that in subjects with nonvalvular AF there was an impairment of the haemorheological profile that seemed more evident in AF subjects with SEC, although no significant haemorheological difference was present between AF subjects with and without SEC. These findings need to be underlined considering that this clinical condition is associated to a major thromboembolic risk.

Abstract
The use of light for probing and imaging of biomedical media offers the promise for development of safe, noninvasive, and inexpensive clinical imaging modalities with diagnostic ability. Various properties of light together with the ways it interacts with biological tissues may provide multiple windows to peer inside body organs. Principles and methods for extraction of information about body functions and lesions that capitalize on temporal, spectral, polarization, and spatial characteristics of transmitted light are briefly outlined. As illustrations of the potential and efficacy of light-based techniques, time-sliced and spectroscopic images of normal and cancerous human breast tissues recorded with a femtosecond Ti:sapphire laser and a broadly tunable Cr:forsterite laser, respectively, are presented.

Abstract
Angiogenesis is a crucial step in tumor growth and progression. Its quantitation by microvessel counting is of prognostic value in several types of malignancies. Scarce data are available on angiogenesis in gastrointestinal tumors. We studied 36 adenomas and 178 large bowel carcinomas to evaluate the onset of angiogenesis in colorectal tumorigenesis and to assess the prognostic significance of microvessel quantitation. Endothelial cells were immunostained with an anti-CD31 mAb; in each case three microscopic fields (x 200) with the highest number of microvessels were counted: the average value of the three fields was used to evaluate the significance of microvessel density (MVD). MVD of normal mucosa (41 cases) served as controls. MVD was 42 +/- 10 in the normal mucosa, 64 +/- 10 in adenomas, and 115 +/- 39 in carcinomas (normal versus adenomas, P < 0.001; adenomas versus carcinomas, P < 0.0001). The transitional mucosa adjacent to carcinomas displayed intermediate levels of MVD (89 +/- 23; P < 0.001 versus adenomas; P < 0.001 versus carcinomas). High MVDs were not associated with metastases, disease stage, and patient survival. The data indicate that angiogenesis is an early, critical step in colorectal tumorigenesis. MVD, however, does not provide significant prognostic information in colorectal cancer patients.

Abstract
The capacity to identify subclinical neoplastic disease of the upper aerodigestive tract (UADT) using tissue auto-fluorescent spectroscopy would significantly contribute to cancer screening. Rats received N-nitrosomethyl benzylamine (NMBA), a carcinogen shown to cause esophageal malignancies. Following sacrifice at early weekly intervals, gross assessment of esophageal mucosa of NMBA-exposed rats was indistinguishable from saline-treated controls. Histopathologic evaluation, however, revealed NMBA-induced preneoplastic changes in the epithelium. Concurrent with these changes, the NMBA-exposed rats demonstrated specific alterations in autofluorescence. These results demonstrate that NMBA-induced esophageal premalignancy can be distinguished by autofluorescent properties. The capacity to detect alterations in autofluorescence may allow more sensitive screening of UADT mucosa at risk for cancer development.

Abstract
Proliferation and differentiation of villous trophoblast during placental development, from an early stage to full-term, were investigated in routinely fixed and processed tissues, by means of the immunocytochemical localization of the cell cycle-related proto-oncogene c-myc and the p53 and retinoblastoma susceptibility (Rb) tumour-suppressor gene products. The proliferative activity of the trophoblast was determined using an antibody against proliferating cell nuclear antigen (PCNA) which stains all proliferating cells in paraffin-embedded tissues. Diffuse nuclear immunoreactivity for PCNA, c-myc and Rb gene products was a consistent finding in early cytotrophoblast; c-myc product expression was also detectable in both layers of mid-gestation trophoblast. Only scattered cytotrophoblastic nuclei of early gestational placenta displayed immunostaining for p53 gene product. In full-term placenta c-myc expression was undetectable while Rb gene product and PCNA immunoreactivity declined markedly. These results indicate that the expression of the above genes is spatio-temporally regulated during placental development. A potential involvement of the oncosuppressor gene products p53 and Rb in the control of trophoblastic proliferation and of c-myc in the control of both the proliferative and differentiation pathways of trophoblastic cells is suggested.
