Relationship between Climate Change, Air Pollution and Allergic Diseases Caused by Ambrosia artemisiifolia (Common Ragweed).

Objective: Influence of climate change and outdoor air pollution (through anthropogenic factors, including heavy traffic, industry and other human activities polluting the environment), which contribute to global warming and increase the allergenicity of some plants (common ragweed) on allergenic patterns, with a direct negative impact on human health, causing or exacerbating allergic respiratory diseases such as bronchial asthma and allergic rhinitis, changing the pattern of respiratory tract infections and premature deaths in Europe. The present study aims to highlight the link between climate change, outdoor air pollution, altered allergenicity of palms and possible behavioural risk factors in the environment. Methods:The clinical studies selected in this research highlighted the links between climate change, air pollutants and the occurrence/exacerbation of aeroallergen-induced respiratory disease; climate change (as an inducer of allergic respiratory disease), increasing global mean ambient air temperature and aeroallergens; climate change, global warming, [CO2] concentration and aeroallergens; climate change, atmospheric humidity, dust storms and aeroallergens; urbanisation (anthropogenic influence), air pollution and aeroallergens; potential of different plant species (common ragweed) for Ni accumulation and possible effects on the human body. Results:The medical implications of increased atmospheric [CO2] concentration are either direct (effect of [CO2] on human physiology and pathophysiology) or indirect (alteration of plant physiology associated with human disease). In an urban area with high [CO2] concentrations, ragweed grows faster, flowers earlier and more intensively, which will lead to increased pollen production compared to rural areas. Over time, climate change leads to changes in allergen (common ragweed) patterns, followed by effects on human health (causing or exacerbating allergic respiratory diseases such as bronchial asthma and allergic rhinitis and changing the pattern of respiratory tract infections). Conclusion:Climate change is changing air pollution patterns, particularly in urbanised areas of the world, with a significant effect on human health. Allergen patterns are also changing in response to climate change. Lifestyle adjustments are important to mitigate the health effects of air pollution and reduce the occurrence and progression of respiratory diseases.

The Role of Neutrophil Extracellular Traps in the Outcome of Malignant Epitheliomas: Significance of CA215 Involvement.

Neutrophil extracellular traps (NETs) were originally discovered as a part of the innate immune response of the host to bacteria. They form a web-like structure that can immobilize microorganisms or exhibit direct antimicrobial properties, such as releasing reactive oxygen species (ROS). NETs are established when neutrophils undergo a sort of cellular death following exposure to ROS, chemokines, cytokines, or other soluble factors. This process results in the release of the neutrophil's DNA in a web-like form, which is decorated with citrullinated histones (H3/H4-cit), neutrophil elastase (NE), and myeloperoxidase (MPO). Emerging studies have put into perspective that NETs play an important role in oncology as they were shown to influence tumor growth, malignant initiation, and proliferation, mediate the transition from endothelial to mesenchymal tissue, stimulate angiogenesis or metastasis, and can even help cancer cells evade the immune response. The role of NETs in cancer therapy resides in their ability to form and act as a mechanical barrier that will provide the primary tumor with a reduced response to irradiation or pharmaceutical penetration. Subsequently, cancer cells are shown to internalize NETs and use them as a strong antioxidant when pharmaceutical treatment is administered. In this review, we explored the role of NETs as part of the tumor microenvironment (TME), in the context of malignant epitheliomas, which are capable of an autonomous production of CA215, a subvariant of IgG, and part of the carcinoembryonic antigen (CEA) superfamily. Studies have shown that CA215 has a functional Fc subdivision able to activate the Fc-gamma-RS receptor on the surface of neutrophils. This activation may afterward stimulate the production of NETs, thus indicating CA215 as a potential factor in cancer therapy surveillance.

"Alphabet" Selenoproteins: Their Characteristics and Physiological Roles.

Selenium (Se) is a metalloid that is recognized as one of the vital trace elements in our body and plays multiple biological roles, largely mediated by proteins containing selenium-selenoproteins. Selenoproteins mainly have oxidoreductase functions but are also involved in many different molecular signaling pathways, physiological roles, and complex pathogenic processes (including, for example, teratogenesis, neurodegenerative, immuno-inflammatory, and obesity development). All of the selenoproteins contain one selenocysteine (Sec) residue, with only one notable exception, the selenoprotein P (SELENOP), which has 10 Sec residues. Although these mechanisms have been studied intensely and in detail, the characteristics and functions of many selenoproteins remain unknown. This review is dedicated to the recent data describing the identity and the functions of several selenoproteins that are less known than glutathione peroxidases (Gpxs), iodothyronine deiodinases (DIO), thioredoxin reductases (TRxRs), and methionine sulfoxide reductases (Msrs) and which are named after alphabetical letters (i.e., F, H, I, K, M, N, O, P, R, S, T, V, W). These "alphabet" selenoproteins are involved in a wide range of physiological and pathogenetic processes such as antioxidant defense, anti-inflammation, anti-apoptosis, regulation of immune response, regulation of oxidative stress, endoplasmic reticulum (ER) stress, immune and inflammatory response, and toxin antagonism. In selenium deficiency, the "alphabet" selenoproteins are affected hierarchically, both with respect to the particular selenoprotein and the tissue of expression, as the brain or endocrine glands are hardly affected by Se deficiency due to their equipment with LRP2 or LRP8.

"Alphabet" Selenoproteins: Implications in Pathology.

Selenoproteins are a group of proteins containing selenium in the form of selenocysteine (Sec, U) as the 21st amino acid coded in the genetic code. Their synthesis depends on dietary selenium uptake and a common set of cofactors. Selenoproteins accomplish diverse roles in the body and cell processes by acting, for example, as antioxidants, modulators of the immune function, and detoxification agents for heavy metals, other xenobiotics, and key compounds in thyroid hormone metabolism. Although the functions of all this protein family are still unknown, several disorders in their structure, activity, or expression have been described by researchers. They concluded that selenium or cofactors deficiency, on the one hand, or the polymorphism in selenoproteins genes and synthesis, on the other hand, are involved in a large variety of pathological conditions, including type 2 diabetes, cardiovascular, muscular, oncological, hepatic, endocrine, immuno-inflammatory, and neurodegenerative diseases. This review focuses on the specific roles of selenoproteins named after letters of the alphabet in medicine, which are less known than the rest, regarding their implications in the pathological processes of several prevalent diseases and disease prevention.

Intra-arterial lidocaine therapy via the middle meningeal artery for migraine headache: Theory, current practice and future directions.

Recent developments in neurointerventional research have seen the emergence of the middle meningeal artery (MMA) as an effective conduit for intra-arterial (IA) therapy for a number of pathologies. Here, we review the anatomical, pathophysiological and experimental basis for utilisation of the MMA for IA treatment of migraine headache. We explore the in-human case literature for the treatment of headaches with IA lidocaine and discuss considerations and challenges for future research.

Exploring Microbiota Diversity in Cervical Lesion Progression and HPV Infection through 16S rRNA Gene Metagenomic Sequencing.

(1) Background: Cervical cancer is a significant health concern, with the main cause being persistent infection with high-risk Human Papillomavirus (hrHPV). There is still no evidence for why viral persistence occurs in some women, but recent studies have revealed the interplay between cervical microbiota and hrHPV. This research aimed to characterize the cervicovaginal microbiota in cervical lesion progression and HPV infection status. (2) Methods: This study included 85 cervical specimens from women from the north-eastern region of Romania. DNA was isolated from cervical secretion for HPV genotyping and 16S ribosomal RNA gene NGS sequencing. (3) Results: Our study revealed a distinct pattern within the studied group when considering Lactobacillus species, which differs from findings reported in other populations. Specifically, the presence of Lactobacillus iners coupled with the absence of Lactobacillus crispatus alongside Atopobium spp., Prevotella spp., and Gardnerella spp. could serve as defining factors for severe cervical lesions. The results also showed a significant association between microbiota diversity, HPV infection, and cervical lesion progression. (4) Conclusions: As the microbiota profile seems to vary among different populations and individuals, a deeper comprehension of its composition has the potential to develop personalized detection and treatment approaches for cervical dysplasia and cancer.

A Narrative Review Discussing the Obstetric Repercussions Due to Alterations of Personalized Bacterial Sites Developed within the Vagina, Cervix, and Endometrium.

BACKGROUND: The reproductive tract microbiota that evolved as an integrative component has been studied intensively in the last decade. As a result, novel research, clinical opportunities, and perspectives have been derived following the close investigation of this microecological environment. This has paved the way for an update to and improvement of the management strategies and therapeutic approaches. However, obscurities, contradictions, and controversies arise regarding the ascension route from the vagina to the endometrium via the cervix, with finality in adverse obstetric outcomes. METHODS: Starting from these considerations, we aimed to gather all existing data and information from four major academic databases (PubMed, ISI Web of Knowledge, Scopus, and ScienceDirect) published in the last 13 years (2010-2023) using a controlled vocabulary and dedicated terminology to enhance the coverage, identification, and sorting of potentially eligible studies. RESULTS: Despite the high number of returned entries (n = 804), only a slight percentage (2.73%) of all manuscripts were deemed eligible following two rounds of evaluation. Cumulatively, a low level of Lactobacillus spp. and of other core microbiota members is mandatory, with a possible eubiosis-to-dysbiosis transition leading to an impairment of metabolic and endocrine network homeostasis. This transposes into a change in the pro-inflammatory landscape and activation of signaling pathways due to activity exerted by the bacterial lipopolysaccharides (LPSs)/endotoxins that further reflect a high risk of miscarriage in various stages. While the presence of some pathogenic entities may be suggestive of an adverse obstetric predisposition, there are still pros and cons of the role of specific strains, as only the vagina and cervix have been targeted as opposed to the endometrium, which recently started to be viewed as the key player in the vagina-cervix-endometrium route. Consequently, based on an individual's profile, diet, and regime, antibiotics and probiotics might be practical or not. CONCLUSIONS: Resident bacteria have a dual facet and are beneficial for women's health, but, at the same time, relaying on the abundance, richness, and evenness that are definitory indexes standing as intermediaries of a miscarriage.

A Narrative Review Discussing Vasectomy-Related Impact upon the Status of Oxidative Stress and Inflammation Biomarkers and Semen Microbiota.

BACKGROUND: Male contraceptive approaches besides tubal sterilization involve vasectomy and represent the method of choice among midlife men in developing countries thanks to many advantages. However, the subsidiary consequences of this intervention are insufficiently explored since the involved mechanisms may offer insight into a much more complex picture. METHODS: Thus, in this manuscript, we aimed to reunite all available data by searching three separate academic database(s) (PubMed, Web of Knowledge, and Scopus) published in the past two decades by covering the interval 2000-2023 and using a predefined set of keywords and strings involving "oxidative stress" (OS), "inflammation", and "semen microbiota" in combination with "humans", "rats", and "mice". RESULTS: By following all evidence that fits in the pre-, post-, and vasectomy reversal (VR) stages, we identified a total of n = 210 studies from which only n = 21 were finally included following two procedures of eligibility evaluation. CONCLUSIONS: The topic surrounding this intricate landscape has created debate since the current evidence is contradictory, limited, or does not exist. Starting from this consideration, we argue that further research is mandatory to decipher how a vasectomy might disturb homeostasis.

An Unusual Case of Urachal Cyst Misdiagnosed as a Paraovarian Cyst: Ultrasound Assessment and Differential Diagnosis.

The urachus is an embryologic remnant of the cloaca that usually degenerates after birth, resulting from the obliteration of the allantois, whose role is to connect the bladder to the umbilicus. Incomplete removal of the lumen may give rise to different malformations of the median umbilical ligament after birth. Although in the pediatric population urachus are common, most cases are asymptomatic and may go unrecognized until adulthood and give rise to cysts, rarely reported in the literature. Thus, in this manuscript we present the circumstances of a 43-year-old Romanian woman showing hypogastric pain of moderate intensity for three weeks, radiation in the left lower limb, menstrual cycle abnormalities, and dysmenorrhea. Based on the initial examinations, a paraovarian cyst measuring 80 mm was noted. Through the subsequent magnetic resonance imaging (MRI) conducted, a hypoechoic mass was detected, and the patient underwent a tumorectomy and partial cystectomy. A 9.7/7.5-cm tumor was excised, and the anatomopathological result was urachal mucinous cystadenoma. It came to our attention that relatively scarce data were found in the literature, with only seven studies with the diagnosis of the urachal cyst.

The Very First Romanian Unruptured 13-Weeks Gestation Tubal Ectopic Pregnancy.

Tubal ectopic pregnancies remain a challenging and life-threatening obstetric condition in the early stages that unavoidably lead to abortion or rupture, further reflected by the associated maternal mortality. Therefore, in the present case report, we report the experience of a 36-year-old woman who presented to our Emergency Department with a history of moderate hypogastric pain, mild vaginal bleeding, and bilateral mastalgia, symptoms that started 20 days ago after uterine curettage for a declarative eight-week pregnancy. On admission, a physical examination showed regular standard signs. The ultrasound examination revealed in the left abdominal flank a gestational sac with a live fetus corresponding to the gestational age of 13 weeks. Given the position of the gestational sac, we suspected a possible abdominal pregnancy. Independently on her human chorionic gonadotropin (hCG) of 33.980 mIU/mL and hemoglobin (Hb) of 13.4 g/dL, the exact location of the pregnancy following ultrasound was hard to establish. Magnetic resonance imaging (MRI) examination was requested, after which we suspected the diagnosis of ovarian pregnancy. Given the paraclinical and clinical context of the worsening of painful symptoms, we decided to perform an exploratory laparoscopy in the multidisciplinary team (digestive and vascular surgeon) that showed the existence of a tubal pregnancy.

An Updated Narrative Mini-Review on the Microbiota Changes in Antenatal and Post-Partum Depression.

BACKGROUND: Antenatal depression (AND) and post-partum depression (PPD) are long-term debilitating psychiatric disorders that significantly influence the composition of the gut flora of mothers and infants that starts from the intrauterine life. Not only does bacterial ratio shift impact the immune system, but it also increases the risk of potentially life-threatening disorders. MATERIAL AND METHODS: Therefore, we conducted a narrative mini-review aiming to gather all evidence published between 2018-2022 regarding microflora changes in all three stages of pregnancy. RESULTS: We initially identified 47 potentially eligible studies, from which only 7 strictly report translocations; 3 were conducted on rodent models and 4 on human patients. The remaining studies were divided based on their topic, precisely focused on how probiotics, breastfeeding, diet, antidepressants, exogenous stressors, and plant-derived compounds modulate in a bidirectional way upon behavior and microbiota. Almost imperatively, dysbacteriosis cause cognitive impairments, reflected by abnormal temperament and personality traits that last up until 2 years old. Thankfully, a distinct technique that involves fecal matter transfer between individuals has been perfected over the years and was successfully translated into clinical practice. It proved to be a reliable approach in diminishing functional non- and gastrointestinal deficiencies, but a clear link between depressive women's gastrointestinal/vaginal microbiota and clinical outcomes following reproductive procedures is yet to be established. Another gut-dysbiosis-driving factor is antibiotics, known for their potential to trigger inflammation. Fortunately, the studies conducted on mice that lack microbiota offer, without a shadow of a doubt, insight. CONCLUSIONS: It can be concluded that the microbiota is a powerful organ, and its optimum functionality is crucial, likely being the missing puzzle piece in the etiopathogenesis of psychiatric disorders.

Controversial Flow Cytometry Monitoring of a Relapse Case of Pediatric T Cell Acute Lymphoblastic Leukemia: A Case Report.

Acute lymphoblastic leukemia (ALL) is the most frequent childhood cancer, with 80-85% represented by B cell ALL and only 15% by T cell ALL. T Cell ALL (T-ALL) carries a more reserved prognosis compared to B Cell ALL (B-ALL) with regard to response to treatment, risk of relapse, and overall survival. Progress made in current monitoring protocols such as via flow cytometry immunophenotyping (FCM) and by PCR-based amplification of antigen-receptor genes led to improved management of patients with ALL and superior rates of survival. Nevertheless, challenges remain in some clinical cases. This manuscript describes a unique case of T-ALL and raises awareness of such clinical challenges. The article presents an overview of the flow cytometry immunophenotyping at diagnosis and during treatment of a pediatric patient with T-ALL from Fundeni Clinical Institute. In this case, in spite of various therapeutic measures such as first-line chemotherapy for high risk group, salvage chemotherapy (FLAG), conditioning regimen (FLU-BU-TT-ATG), and stem cell transplant, a chemoresistance clone continued to be present.

PM10 and NO2 Air Pollution and Evolution of COVID-19 Cases in Romania.

Objectives:Based on the correlation between air pollution and COVID-19 incidence/mortality already existing in the literature, we aimed to develop a study to investigate the link between the average level of PM10 (particulate matter 10 - particulate matter 10 microns in diameter) and NO2 (nitrogen dioxide) concentration over five years and the cumulative incidence of COVID-19 cases per 1000 people in Romania. Methods: To assess PM10 and NO2 exposure, we determined the average value of annual PM10 and NO2 concentration for each city over five years (2015-2019). For this purpose, the average of annual PM10 and NO2 concentrations collected from monitoring stations in selected cities was calculated. Then, the annual values over five years were averaged to finally obtain the average PM10 and NO2 concentration for each city. Data on the cumulative number of confirmed cases of COVID-19 up to the 28th of September 2020 were provided by the National Centre for Surveillance and Control of Communicable Diseases (CNSCBT) of the National Institute of Public Health (INSP). The study used the cumulative incidence/hour per 1000 population on 28.09.2020. Results:According to Law no. 104/2011, the annual permissible limit value of PM10 concentration of 40 µg/m³ was not exceeded in any of the 43 cities in our study. The average for all cities was 24.0±4.8 ìg/m³, with a minimum value of average PM10 concentration of 13.9 µg/m3 measured in Alba Iulia and a maximum value of 39.1 µg/m³ in Iasi. The regression model shows that, in Bucharest, 77.9% of the variation in case incidence is explained by the variation in PM10 concentration. In order to find the number of new cases that would correspond to a cumulative incidence of 0.166, taking as an example one of the districts with a population of 259,084, the above regression model shows that an increase in the average PM10 concentration by one unit is associated with 43 new cases. Conclusion:The study demonstrates that an exposure of the population to particulate matter in atmospheric air, at low values, below the permissible limit values but for a long time (the follow-up period in our study was five years, between 2015 and 2019), can have effects on the health status of the population, which becomes much more vulnerable to external agents, in our case pathogenic microorganisms (viruses).

Molecular and Clinical Insights on the Complex Interaction between Oxidative Stress, Apoptosis, and Endobiota in the Pathogenesis of Endometriosis.

Endometriosis (EMS) remains, to date, an intriguing and debilitating gynecological disorder that possesses a multifactorial substrate. Recent studies with the objective of elucidating its etiology highlighted the antagonistic effect of EMS on a multiple of processes involved in homeostasis. Although the current oxidative biomarkers clearly reveal the consequences induced by EMS, its implication in the associated inflammatory reactions could be much more complex. Besides the overproduction of reactive oxygen species (ROS) that leads to an exacerbated oxidative response, it also changes the normal expression of several pro-inflammatory modulators, reflected by the fluctuating activity of several pro- and anti-apoptotic mediators whose expression is impaired. In light of this topic, several studies elucidate the involvement of apoptosis in EMS, being brought controversial findings, even reports with no significant change. Further, some authors reported an abnormal expression of multiple genes that are crucial for the overall functionality of the female reproductive system. Cumulatively, it seems that the subsequent oxidative imbalance and apoptosis process impairment could further disrupt the normal removal of unnecessary biological products. Based on all gathered evidence, we could argue that the related stress state could determine human endobiota impairment, which could further participate in the inflammatory and main antioxidant enzyme changes occurring in EMS. Moreover, a correlation between endobiota integrity, inflammation, and oxidative stress (OS) was suggested in relation to the possible predisposition to pathogen determined infections.

Alcoholic liver disease-from steatosis to cirrhosis - a biochemistry approach.

Nowadays, chronic alcoholism and its health implications represent a global concern. Over three million deaths are linked to chronic alcohol intake every year. This article aims to spread awareness about the negative impact ethanol can have on almost every organ in the body, especially the liver. Understanding ethanol metabolism and the cellular pathways through which alcohol increases liver oxidative stress may prevent a broad spectrum of hepatic lesions such as steatosis, steatohepatitis, and, ultimately, cirrhosis. After a short review of ethanol metabolism and liver oxidative stress, each hepatic lesion will be individually discussed regarding the mechanism of apparition, treatment, and future targeted therapies.

Concentration of heavy metals and rare earth elements in patients with brain tumours: Analysis in tumour tissue, non-tumour tissue, and blood.

Inorganic elements have been associated with brain tumours for long. The blood concentration of 47 elements was assessed by ICP-MS in 26 brain tumour patients and 21 healthy subjects from Bucharest (Romania). All 47 elements were detected in the brain tumour tissue, and 22 were detected in > 80% of samples; this implies that these elements can cross the blood-brain barrier. Median blood levels of cadmium, lead, and nickel were higher than the reference values (1.14, 53.3, and 2.53 ng/mL). Gadolinium and tantalum showed significantly higher concentrations among cases. We observed considerable differences and different profiles of the presence of inorganic elements between the tumour and non-tumour brain tissue and between tissue from the primary tumour and tissue from brain metastasis. Our data suggest that similar to heavy metals, other elements - commonly used in high tech devices and rare earth elements - can also influence brain tumour.

Serum concentration of toxic metals and rare earth elements in children and adolescent.

Biomonitoring studies are important for quantifying the body burden of pollutants and their possible effects on health. Serum concentration of 42 elements was assessed by ICP-MS in 89 children (7.2 ± 3.4 years old) from Bucharest (Romania). Levels of pollutants were compared with the clinical data obtained from routine blood tests. Clinical parameters were in the physiological range. Deficiencies of manganese, selenium, and zinc were discovered. Blood levels of elements were low. The highest levels were observed among children younger than six years. The sum of iron, selenium, barium, nickel, antimony, and cerium was positively associated with hemoglobin (Spearman rho = 0.217, P-value = 0.041), while the sum of copper, thallium, niobium, and tantalum was negatively associated (Spearman rho = -0.228, P-value = 0.032). Given the inherent sensitivity of the child population, additional studies are needed to assess the effects of these elements on their health.

A Case of Ectopic Tubal Pregnancy Eight Years After a Hysterectomy Presenting as a Diagnostic Challenge.

BACKGROUND Ectopic pregnancy after hysterectomy is extremely rare, and the diagnosis can be challenging, even with modern imaging methods. A rare case is presented of ectopic tubal pregnancy in a 28-year-old woman that presented eight years following a hysterectomy. CASE REPORT A 28-year-old woman was admitted in our hospital with moderate hypogastric pain, mild vaginal bleeding, and bilateral mastalgia. She had undergone hysterectomy eight years previously for postpartum hemorrhage. Pelvic ultrasound showed a heterogeneous tissue mass in the pelvis with peripheral vascularity that was also seen on magnetic resonance imaging (MRI). Laboratory tests showed increased serum levels of human chorionic gonadotropin (hCG). Following hospital admission, she developed an acute abdomen and shock due to tubal rupture and an emergency salpingectomy was performed. CONCLUSIONS A multidisciplinary approach to diagnosis and management facilitated an accurate and timely diagnosis in a rare case of ectopic pregnancy that presented eight years following hysterectomy, but could not prevent the development of potentially life-threatening complications.

Polymorphism of clinical manifestation of HPV infection in the genital mucosa - 3-year retrospective study.

BACKGROUND: Human papillomaviruses (HPVs) are associated with a wide variety of cutaneous and mucosal infections and with malignancies in humans. More than 100 HPV types have been identified, some of which have affinity for skin and others for mucosal sites. AIM: The purpose of this study came from our desire to support the "Stop Cervical Cancer" campaign, adopted as "Cervical Cancer Removed as a Public Health Problem", following the World Health Organization (WHO) initiative in 2019-2020. At European level, cervical cancer mortality has fallen by more than 30% over the past 30 years, through coherent, consistent and comprehensive prevention programs based on accurate and consistent public information. Romania is in an unfavorable situation with regard to incidence (32.8 new cases∕100 000 women) and cervical cancer mortality (10.9 deaths∕100 000 women). Free Babes-Papanicolau (Pap) testing for early detection of cervical cancer was valid this year until March. PATIENTS, MATERIALS AND METHODS: The study runs over a period of three years, between 2016-2018, in the "Elena Doamna" Hospital of Obstetrics and Gynecology, Iasi, Romania. Of the 8500 patients hospitalized for various diseases (ovarian cysts, uterine fibroids, endometriosis, abnormal vaginal bleeding, dysmenorrhea, ectopic pregnancies, placenta praevia, spontaneous abortions and on demand, benign, malignant tumors), only 382 were present in the ambulatory for Pap test. For the other conditions, Pap test denied because the patients did not want this but to solve the condition for which they presented themselves. RESULTS: We retrospectively review 382 Pap tests of patients who presented themselves in the Ambulatory Service of the Hospital both at the advice of the gynecologist and due to the program initiated by the WHO and supported by the Department of Public Health, Iasi: "Cervical cancer can be eliminated as a problem of public health". Lesions equal to or worse than high-grade squamous intraepithelial lesion (HSIL) equivalate with high-grade lesions including HSIL (cervical intraepithelial neoplasia - CIN1, CIN2). Endometrial lesions were excluded from the study. As seen of this campaign, the number of patients has increased in 2018 (242 cases), compared to 46 cases in 2017 and 94 cases in 2016. CONCLUSIONS: Our study demonstrated that 35% (7/20) of HSIL-confirmed biopsies previously had negative HPV assays. Despite the previous negative HPV tests, a wide variety of HPV genotypes has been detected in most biopsies. In our case, we frequently identified the HPV 59 and 45 strains, 51 cases with HSIL lesions presented a first positive HPV test, 13 cases with low-grade squamous intraepithelial lesion (LSIL) showed three negative HPV tests. Prevention plays an important role in reducing the incidence of cervical cancer cases. The Pap test is now considered the primary prevention method, but consecutive vaccination significantly increases protection against high-risk HPV strains. Education plays an important role in the prophylaxis of HPV infection and cancer. It should be instituted in schools, from puberty age through partnerships or government programs with public health directorates and university hospitals or using European funds.
