RESUMO

BACKGROUND: Electrical impedance measurements have become an accepted tool for monitoring intracardiac radio frequency ablation. Recently, the long-established generator impedance was joined by novel local impedance measurement capabilities with all electrical circuit terminals being accommodated within the catheter. OBJECTIVE: This work aims at in silico quantification of distinct influencing factors that have remained challenges due to the lack of ground truth knowledge and the superposition of effects in clinical settings. METHODS: We introduced a highly detailed in silico model of two local impedance enabled catheters, namely IntellaNav MiFi OI and IntellaNav Stablepoint, embedded in a series of clinically relevant environments. Assigning material and frequency specific conductivities and subsequently calculating the spread of the electrical field with the finite element method yielded in silico local impedances. The in silico model was validated by comparison to in vitro measurements of standardized sodium chloride solutions. We then investigated the effect of the withdrawal of the catheter into the transseptal sheath, catheter-tissue interaction, insertion of the catheter into pulmonary veins, and catheter irrigation. RESULTS: All simulated setups were in line with in vitro experiments and in human measurements and gave detailed insight into determinants of local impedance changes as well as the relation between values measured with two different devices. CONCLUSION: The in silico environment proved to be capable of resembling clinical scenarios and quantifying local impedance changes. SIGNIFICANCE: The tool can assists the interpretation of measurements in humans and has the potential to support future catheter development.

RESUMO

Background and Objectives: The aim of this study was to investigate the association between H. pylori positivity with specific symptoms, risk factors and endoscopic patterns among the pediatric population in northeastern Romania. Materials and Methods: A prospective study was performed in 18 months on 185 children aged 6−18 years with an indication for upper digestive endoscopy. Demographic, anamnestic, symptomatic, endoscopic and histologic data were recorded. Results: Of 116 H. pylori-positive children, the most affected group was 15−17 years. Most (65.5%) of them were girls, with a significant association (p < 0.001). The majority (66.4%) lived in a rural area and 47.4% of children had an unsafe source of water and lived in overcrowded houses with no basic sanitary comfort. The most frequent symptom was epigastric pain (56.9%), and the main endoscopic appearance was nodularity and hyperemia. Patients diagnosed with H. pylori started triple-therapy treatment for 14 days. Only 13.8% stopped the treatment, mainly because of a misunderstanding of the treatment protocol (9.5%). Conclusions: Romanian teen girls living in rural areas are at high risk for H. pylori infection. Epigastric pain and endoscopic nodularity of the gastric mucosa were associated with the infection. As the resistance of the bacteria is unknown in our country, future research is needed in order to improve the eradication rate.

RESUMO

(1) Background: Irritable bowel syndrome (IBS) is a common disease, with multiple pathophysiological mechanisms involved. A single treatment for all the patients with IBS is not possible. Prebiotics may have a beneficial effect on IBS patients with constipation. (2) Methods: A randomized cross-over case-control study was conducted, including patients with IBS and constipation (IBS-C), who were randomized into two groups receiving a specific constipation diet with or without a food supplement containing inulin, choline and silymarin (Stoptoxin®, Fiterman Pharma, Iasi, Romania). Patients were evaluated at baseline, after four and eight weeks, using a questionnaire to assess IBS symptoms. (3) Results: 51 IBS-C patients were included, of which 47 patients finished the trial (33 women, mean age 52.82 years). Adding Stoptoxin® to a diet for constipation brought extra benefits. Abdominal pain severity improved by 68.3% after the diet and Stoptoxin® (p = 0.004) and abdominal bloating severity parameter improved by 34.8% (p = 0.040). The stool number per week and the stool consistency according to the Bristol scale were improved, but without statistical significance between groups (p > 0.05). (4) Conclusions: The combination of inulin, choline and silymarin associated with a specific-constipation diet had obvious clinical beneficial effects on IBS-C patients in terms of bowel movement, abdominal pain and bloating.

RESUMO

INTRODUCTION: In hemodialysis patients, coronavirus disease 2019 is associated with high morbidity and mortality. Aim of the study was to evaluate the antibody level against severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) in patients treated with two different mRNA-based vaccines, in a multicenter survey. PATIENTS AND METHODS: Since April 2020, in the 5 participating Centers, periodic screening of all patients with PCR testing has been performed every 2 weeks. The study included two cohorts of patients on maintenance hemodialysis treated with the BNT162b2 or with the mRNA-1273 Covid-19 vaccine. The tests for antibodies against the receptor-binding domain was performed by the anti-SARS-CoV-2 S enzyme immunoassay (Roche Elecsys). RESULTS: Of the 398 included patients, 303 received the BNT162b2 and 95 the mRNA-1273 vaccine. In patients without previous infection, the median levels of anti-S antibodies were 297 U/mL and 1,032 U/mL for those treated with BNT162b2 or mRNA-1273, respectively (p < 0.001). In patients with previous infection, the median levels of SARS-CoV-2 anti-S antibodies were 7,516 U/mL and 17,495 U/mL for those treated with BNT162b2 or mRNA-1273, respectively (p = 0.005). The Charlson comorbidity index (CCI) was significantly associated with protective levels of anti-spike IgG, with 3.6% of low- or non-responders having a CCI of 2-4 versus 18.9% in those with a CCI of 8 or more. The adjusted OR of developing a sufficient antibody level between the two vaccines was 3.91 (p = 0.0766) in favor of mRNA-1273. CONCLUSIONS: Both of the evaluated mRNA-based vaccines for SARS-CoV-2 showed good efficacy. Preliminary data may data suggest a  higher antibody response to the mRNA-1273 vaccine.

RESUMO

Infertility is defined as the inability to procreate, or carry or deliver a baby naturally. The majority of specialists describe infertility as being unable to get pregnant after having tried for at least one year. The relationship between infertility and psychological stress is complex. On the one hand, infertile couples are subject to greater stress and have a greater risk of developing psychological disorders compared with normal, healthy couples. On the other hand, high levels of psychological distress have been indicated to increase infertility. Therefore, in the present review, the main factors that may lead to increased stress in couples who try to conceive, psychological stress as the reason for infertility, and the therapies that can help decrease psychological distress and increase chances of pregnancy are underlined. In addition to the psychological side effects that may occur from infertility itself, a range of other side effects can be caused by hormones and drugs used to treat infertility. Additionally, problem during erection and ejaculation can cause of psychological distress, which can lead to infertility among men. Psychotherapy is the main intervention recommended for couples who suffer from any form of infertility. Ideally, counselling should begin before patients start any medical intervention to help with their infertility.

RESUMO

Primitive neuroectodermal tumor (PNT) and Ewing's sarcoma are rare, round-cell tumors, characterized by the presence of the t(11; 22)(q24; q12) chromosomal translocation. A review of the literature revealed only 38 previously reported cases of vulvar PNT and Ewing's sarcoma and 15 vaginal PNT and Ewing's sarcoma. Although rare, these types of tumors should be taken into consideration when making a differential diagnosis for vulvar or vaginal tumors. The currently available data is limited, and therefore, case reports are essential for improving knowledge and management of these types of extremely rare tumors. However, further molecular and histopathological studies are essential for an improved understanding of these conditions and for an early, correct diagnosis. Although the gathered and presented data from the present review are limited, the literature demonstrates that the outcome of these types of cancer are more favorable compared with outcomes observed for carcinomas in more typical locations.

RESUMO

BACKGROUND: Irritable bowel syndrome (IBS) patients' use of the Internet for health information interacts with the way they trust their gastroenterologist. No standardized measure has targeted IBS patients and gastroenterologists specifically, nor their use of the Internet. The aims of this paper were as follows: the development of a scale that measures an IBS patient's trust in their gastroenterologist, the development of a scale measuring an IBS patient's reliance on Internet health information, and testing the hypothesis that IBS patients, who use the Internet for IBS-related information, trust their gastroenterologist less than those who do not. METHOD: A total of 82 patients (mean age 49, SD = 14.62) diagnosed with IBS completed two questionnaires: one about trust in their gastroenterologist and the other about the reliance on Internet health information regarding IBS. The two questionnaires were built using current literature as well as our previous qualitative research. The statistical computations were performed using the SPSS 20 program. KEY RESULTS: Both questionnaires proved to be reliable in measuring gastroenterologist-IBS patient trust (alpha = 0.87) and Internet information reliance (alpha = 0.88), respectively. The IBS patients who did not look for information about IBS over the Internet had significantly higher trust in their gastroenterologist compared with those who did (U = 535.5; z = -2.26; P < 0.05). CONCLUSIONS: We developed two ready-to-use scales to measure both the gastroenterologist-IBS patient's trust and the IBS patient's reliance on the Internet. Further studies will be able to explore the interaction among all variables in IBS patients' trust.

RESUMO

The treatment of atrial fibrillation and other cardiac arrhythmias as a major cause of cardiovascular hospitalization has remained a challenge predominantly for patients with severely remodeled substrate. Individualized ablation strategies are extremely important both for pulmonary vein isolation and subsequent ablations. Current approaches to identifying arrhythmogenic regions rely on electrogram-based features such as activation time and voltage. Novel technologies now enable clinical assessment of the local impedance as tissue property. Previous studies demonstrated its use for ablation monitoring and indicated its potential to differentiate healthy substrate, scar, and pathological tissue. This study investigates the potential of local electrical impedance-based substrate mapping of the atria for human in-vivo data. The presented pipeline for impedance mapping particularly contains options for dealing with undesirable effects originating from cardiac motion, catheter motion, or proximity to other intracardiac devices. Bloodpool impedance was automatically determined as a patient-specific reference. Full-chamber, left atrial impedance maps were drawn up from interpolating the measured impedances to the atrial endocardium. Finally, the origin and magnitude of oscillations of the raw impedance recording were probed into. The most dominant reason for exclusion of impedance samples was the loss of endocardial contact. With median elevations above the bloodpool impedance between 29 and 46 Ω, the impedance within the pulmonary veins significantly exceeded the remaining atrial walls presenting median elevations above the bloodpool impedance between 16 and 20 Ω. Previous ablation lesions were distinguished from their surroundings by a significant drop in local impedance while the corresponding regions did not differ for the control group. The raw impedance was found to oscillate with median amplitudes between 6 and 17 Ω depending on the patient. Oscillations were traced back to an interplay of atrial, ventricular, and respiratory motion. In summary, local impedance measurements demonstrated their capability to distinguish pathological atrial tissue from physiological substrate. Methods to limit the influence of confounding factors that still hinder impedance mapping were presented. Measurements at different frequencies or the combination of multiple electrodes could lead to further improvement. The presented examples indicate that electrogram- and impedance-based substrate mapping have the potential to complement each other toward better patient outcomes in future.

RESUMO

The presence of teeth on babies earlier than four months is a rare condition. Therefore, adequate treatment for each case should be instituted as soon as possible, considering that certain complications may arise. This report describes a rare case in which a newborn baby required the extraction of two mobile mandibular natal teeth to prevent the risk of aspiration. After two years, the clinical re-evaluation showed a residual tooth instead of a temporary one. This case report shows that adequate diagnosis should include a radiographic examination to determine whether these teeth are components of normal or supernumerary dentition, as well as further investigations on the relationship with the adjacent teeth. Another important aspect highlighted in this case report is the need for a post-extraction curettage of the socket in order to reduce the risk of ongoing development of the dental papilla cells.

RESUMO

Irritable bowel syndrome (IBS) is a gastrointestinal disease that negatively affects up to 20% of the population. Infertility is defined as a disorder of the reproductive system described by lack of success in achieving pregnancy after more than a year of regular unprotected sexual intercourse. The main purpose of our review was to analyze the available literature regarding the IBS-infertility connection. Another secondary purpose of the present paper was to find out if oxidative stress may be the missing puzzle that may explain this possible correlation. After analyzing the available literature we concluded that oxidative stress is a plausible mediator of the connection between both female and male fertility and IBS. However, the data lacks in direct evidence to confirm this hypothesis. Nevertheless, it is recommended that certain levels of oxidative stress should not be exceeded in order to decrease IBS symptoms and increase the odds of conception given that generation of reactive oxygen species (ROS) is an aftermath of metabolically active cells. Therefore, reducing the oxidative stress by living a healthier lifestyle with a balanced diet, rich in micronutrients, limited in caffeine and alcohol, avoiding smoking and maintaining a normal body mass index with regular physical exercise may promote fertility and help diminishing IBS symptomatology. Studies with measurements of biological samples are needed in order to assess the complex relationship between oxidative stress, IBS and infertility.

RESUMO

At present, irritable bowel syndrome (IBS) is a common medical problem all over the world that implies considerable social burden and high costs. Considering the different pathophysiological pathways, unitary management for IBS is not possible. Of the therapeutic approaches that have been proposed so far, only a few have been demonstrated to have beneficial effects in IBS patients. The implication of gut microbiota in IBS is obvious, similarly to the therapeutic effect of pro-/prebiotics, which is reflected by the latest publications. The intake of inulin seems to regulate the bowel peristalsis and colonic transit, the consistency and frequency of the stools, as it changes the composition of gut microbiota. The beneficial effect of inulin in patients with IBS-constipation form (IBS-C) is obvious, but still, more randomized controlled clinical trials involving large samples of patients are needed in order to provide more evidence.

RESUMO

Background and Objectives: Over the last years, inflammatory bowel disease (IBD) has been reported on a high incidence in pediatric populations and has been associated with numerous extraintestinal manifestations, making its management a real challenge for the pediatric gastroenterologist. Dermatological manifestations in IBD are either specific, related to the disease activity or treatment-associated, or non-specific. This literature review aims to identify and report the dermatological manifestations of IBD in children, the correlation between their appearance and the demographical characteristics, the relationship between these lesions and disease activity, and to highlight the impact of dermatological manifestations on an IBD treatment regime. MATERIALS AND METHODS: A systemic literature review was performed, investigating articles and case reports on dermatological manifestations in children with IBD starting from 2005. A total of 159 potentially suitable articles were identified and after the exclusion process, 75 articles were selected. RESULTS: The most common dermatological manifestations reported in pediatric IBD are erythema nodosum and pyoderma gangrenosum. More rare cases of metastatic Crohn's disease, epidermolysis bullosa acquisita, small-vessel vasculitis, necrotizing vasculitis, leukocytoclastic vasculitis, cutaneous polyarteritis nodosa, and Sweet's syndrome have been reported. Oral manifestations of IBD are divided into specific (tag-like lesions, mucogingivitis, lip swelling with vertical fissures, aphthous stomatitis, and pyostomatitis vegetans) and non-specific. IBD treatment may present with side effects involving the skin and mucosa. Anti-tumor necrosis factor agents have been linked to opportunistic skin infections, psoriasiform lesions, and a potentially increased risk for skin cancer. Cutaneous manifestations such as acrodermatitis enteropathica, purpuric lesions, and angular cheilitis may appear secondary to malnutrition and/or malabsorption. CONCLUSIONS: The correct diagnosis of dermatological manifestations in pediatric IBD is of paramount importance because of their impact on disease activity, treatment options, and a patient's psychological status.

RESUMO

Plan de cuidados individualizado para un paciente de 77 años que desarrolla una fístula enterocutánea de alto débito tras varias cirugías urgentes, debidas a complicaciones en el postoperatorio de una eventroplastia compleja y hemicolectomía derecha urgente por diagnóstico de suboclusión intestinal y eventración paraestomal. El manejo inicial se realizó con terapia de presión negativa. Debido al gran número de fugas e irritación de la piel, se optó por la bolsa de drenaje postquirúrgico Sistema para el manejo de Fístulas y Heridas Coloplast(R). El principal objetivo de los cuidados debe ser la protección de la piel frente al efecto corrosivo del efluente, para favorecer la epitelización, la disminución de la pérdida de la integridad cutánea y mejorar notablemente la calidad de vida percibida por el paciente. Una apropiada selección del material de curas y los cuidados individualizados permiten alcanzar estos objetivos

RESUMO

UNLABELLED: Breast cancer is the second leading cause of cancer death in women, while in Eastern Europe the most common form of diagnosed cancer. Out of the multiple possibilities of early detection of mammary neoplasia that have been elaborated, only mammography has proved to be a simple, efficient method and of a high sensitivity, almost 90% However, the cytological confirmation of diagnosis allows us to perform the preoperative radiotherapy treatment or poly chemotherapy. MATERIAL AND METHODS: we analyzed the informative value of these diagnosis methods in stage I mammary gland cancer (MGC). In this way, in the present paper we demonstrated that collecting samples through fine-needle aspiration biopsy allows the cytological confirmation of the diagnosis of stage I MGC in 30.7% cases. RESULTS AND DISCUSSION: In stage I MGC young patients, under 35 years, the cytological confirmation rate is 22.2% and is lower as compared to the cytological confirmation rate in patients older than 35 years which is 37.9% Also, for a tumor diameter < 0.5 cm, the prevalence of cytological confirmation was only 10.3%, while for the diameter of 0.6-1.0 cm the cytological confirmation was around 40.0%. Therefore, in order to improve the cytological diagnosis confirmation rate the tumor biopsy through the USG of the mammary glands is required. Moreover, the cytological investigation of the smear obtained by the first and second puncture was instrumental in confirming the diagnosis in 41.3% and 17.4% cases; the subsequent repetition of the punctures was not useful as it helped to confirmation of the diagnosis only in 9.3% cases. The frequency of diagnosis cytological confirmation depends on the tumor histopathological form and type of growth. CONCLUSIONS: Thus, the lowest prevalence was in the mixed forms--12.5% cases, lobular cancer--24.4% cases, while regarding the type of growth, for the rare forms the cytological confirmation rate was 7.7% and 31.5% cases for the schiros growth type.

RESUMO

Breast cancer is the most common oncology disease in women and is one of the major public health issues. Worldwide, is the second leading cause of cancer death in women and cancer research is a priority in all the laboratories of the world, in terms of uncovering the appearance causes of the malignant process, understanding the mechanisms of development, but most of all, the discovery of early diagnostic methods and effective treatment. Ignorance, fear of diagnosis, lack of health education and of efficient programmes for prevention and screening could cause diagnosis of the disease to be detected in the majority of cases in advanced stages, when treatment remains only palliative and very costly, in this cases the patient's suffering being immense. In this way, regarding the clinical diagnosis in stage I mammary gland cancer, in the 496 stage I MGC patients, during the primary clinical investigation the diagnosis of stage I MGC was established only in 165 (33.3%) patients, and in 232 (46,8%) patients the diagnosis of suspicion MGC was obtained. Also, in terms of instrumental diagnosis, such as mammography, ultrasonography in mammary gland cancer stage I, it seems that in accordance with literature data the pathological process features assessment in the mammary gland is problematic especially in young age. Thus, it seems that MGC represents a polymorphic and pathogenic disease and it cannot be admitted that all subgroups of patients will obtain identical results from one tactic of treatment determined for all the patients with MGC. In this way, the concept of MGC both clinical and patho morphological, combines different cell clones depending on its microstructure and biology. As a result, the evolution of the disease, the prognosis and the effectiveness of the treatment may vary in different patients at the same stage, depending on the degree of malignancy of the tumor, its histopathological structure, the degree of expression of molecular markers identification and also immune resistance.

RESUMO

In the pathophysiology of hepatic encephalopathy (HE), a serious complication of liver cirrhosis, different hypotheses, including increased blood ammonia levels, increased production and absorption of intestinal bacterial products are discussed. Recent studies demonstrated that Helicobacter pylori infection is associated with elevated blood ammonia levels. Inflammatory mediators and cytokines also play important roles along with hyperammonia in the pathogenesis of HE, while recent studies revealed correlations between CRP levels and length of hospital stay. Neuropsychological diagnostic tests, such as Psychometric Hepatic Encephalopathy Score, were especially designed for detecting minimal HE. Imaging investigations, like Computed Tomography or Magnetic Resonance Imaging, show characteristic aspects in advanced stages of liver disease. Recent studies revealed that Mini-Mental State Examination (MMSE) can show significant changes mostly in advanced stages of overt HE, but that it is not an appropriate tool in defining an encephalopathy-related status of patients with cirrhosis.

RESUMO

UNLABELLED: Rheumatoid myositis (RM) is still poorly characterized, albeit the concept of muscle involvement in rheumatoid arthritis (RA) is well-recognized as being driven by a wide range of causes including inflammation, drugs, impaired joint flexibility, sedentarism. OBJECTIVE: To describe clinical, serological, imaging and histological pattern of RM. MATERIALS AND METHODS: This is a retrospective study on eight RM selected from a cohort of one hundred and three RA systematically assessed for skeletal muscle involvement. Data collected included clinical, serum muscle enzymes, muscle imaging and biopsy (Hematoxylin-Eosin, modified Gömöri trichrome staining). RESULTS: Routine muscle histology indicated both non-specific muscle fiber damage (changes in fiber size and internal structure: pleomorphic mitochondria, dilated sarcotubular system, multiple internal or subsarcommal nuclei; abnormal fiber types distribution: trend towards type II; atrophy; degenerative/regenerative modifications) and the presence of inflammatory deposits in all patients (mild to moderate, patchy B- and T-cells infiltrates, mainly perivascular and endomysial, but also in the perimysial region classified as polymyositis-like deposits). High levels of serum muscle enzymes, abnormal EMG (short duration, small amplitude, polyphasic motor unit action potentials) without insertional activity and fibrillations, active inflammation on both Doppler ultrasound and MRI were commonly reported. CONCLUSIONS: Traditional analysis of muscle biopsy specimens (Hematoxylin-Eosin, modified Gömöri trichrome staining) is faraway unsatisfactory, only documenting changes in muscle fibers size, architecture, internal structure, and, possibly, detecting perivascular, perimysial or endomysial inflammatory deposits. Upcoming research should address the value of muscle imaging for the diagnosis and evaluation of treatment response and muscle function in rheumatoid myositis.

RESUMO

UNLABELLED: There is no doubt that the association between infection of the cervical epithelium by carcinogenic Human Papilloma Virus (HPV), particularly types 16 and 18, and cervical cancer (CC) is responsible for the activation of the immune response (IR). Research on tumor infiltrating lymphocytes at the primary tumor site could give us important information on how the immune cells are fighting against cancer. AIM: The aims of our study were to assess HPV status and to evaluate the significance of in situ cellular IR in CC. MATERIALS AND METHODS: We performed a two-step retrospective analysis of IR in 18 CC: evaluation of HPV 16 and 18 infections by in situ hybridization and immune biomarkers (CD20, CD3, CD45) by immunohistochemistry. Immune cell profile, densities (assigned scores "0" if no inflammatory infiltrate, "1+" low, "2+" intense), tissue distribution and classical negative prognosis factors in relationship with survival and relapse were further assessed. RESULTS: We successfully demonstrated HPV 16 and/or 18 in all cases. We reported statistical significant correlations (p<0.005) between CD3, CD20, CD45 and survival (r=0.800), relapse (r=-0.892), clinical stage (r=-0.914), tumor size (r=-1) as well as the association between survival and CC subtype (r=0.548), FIGO stage (r=-0.914), tumor size (r=-0.800) and grading (r=0.61). CONCLUSIONS: The density of different immune cells is significantly involved in guiding prognosis of the CC in high-risk 16 and 18 HPV positive women; low cellular densities for CD3, CD20 and CD45 meaning limited immune response reflect negative disease outcomes promoting local relapse and decreased survival in such settings.

RESUMO

UNLABELLED: Thrombotic thrombocytopenic purpura (TTP) is a rare but severe disease characterized by mechanical hemolytic anemia and consumptive thrombocytopenia leading to disseminated microvascular thrombosis that causes signs and symptoms of organ ischemia and functional damage. TTP is diagnosed by the presence of microangiopathic hemolytic anemia and thrombocytopenia in a patient who frequently presents with central nervous system involvement and, to a lesser extent, renal dysfunction. CASE REPORT: We present the case of a 23-year-old female with TTP, diagnosed by the presence of the neurological symptoms, microangiopathic hemolytic anemia and severe thrombocytopenia (platelets 4000/µL). During the clinical evolution, the patient presented the hepatic cytolysis syndrome, following disseminated microvascular thrombosis inside the liver, representing an atypical damage. The diagnosis was difficult because it was necessary to make differential diagnosis with other diseases that evolve with microangiopathic hemolytic anemia in a short time to be able to initiate plasmapheresis. Initiation of the plasmapheresis as soon as possible was the goal of our treatment. Following the plasmapheresis combined with administration of corticosteroids was achieved complete resolution of all symptoms. CONCLUSIONS: TTP is a hematological emergency and diagnostic challenge. The critical determinant of outcome is timely diagnosis and treatment. Once the diagnosis is suspected, life-saving therapeutic plasma exchange therapy is initiated.

RESUMO

UNLABELLED: Chronic inflammation of the cervix can develop cervical stenosis with infertility and cervical congestion is related with the cervical cancer. We create a review of main etiological agents and methods of screening and diagnosis. We also make a brief review of modern therapeutic approach. CONCLUSIONS: We follow the utility of LLLT through the following aspects: evolution, indications, results of Babes-Papanicolau screening, cytology, clinical aspects. The results of the study will allow the complex system of treatment to be used in a large category of women. We appreciate that the procedure (used in our center also) will decrease the cervical pathology, the morbidity inside the treatment, the mortality through the evolution of cervical cancer. We propose the applicability for outpatients first and then as an integrated treatment method inside hospitals for a wide access.
