Cervical cancer remains a significant global public health issue, particularly in Low-and Middle-Income Countries (LMICs), where its burden is disproportionately high. Although there has been increasing attention from the global scientific community, governmental actions have not aligned with the ambitious targets set by the World Health Organizati...

Background: To compare the efficacy of CO2 fractional laser with that of topical estriol for treating genitourinary syndrome of menopause and to investigate the relationship between epithelial thickness and vaginal atrophy. Methods: Twenty-five menopausal women were randomized to receive either laser or estrogen treatment. Vaginal biopsies before a...

Introduction: Xingu Indigenous Park (XIP) currently protects 16 ethnic Indigenous groups and is located in the central area of Brazil. XIP is the first and the largest Indigenous land to be recognized in the country. Community access is limited and restricted for the non-Indigenous population, and the Indigenous women are constantly dealing with s...

Embora o câncer do colo do útero seja uma doença prevenível e tratável, permanece sendo um dos mais frequentes em mulheres, particularmente nos países mais pobres. A vacinação contra o HPV (vírus associado ao câncer cervical) prevenirá de forma importante o câncer nas gerações futuras. Porém, no curto prazo, o rastreamento é uma estratégia fundamen...

Objectives: In this pilot, prospective, randomized, double-blind study, the authors compared the efficacy of oxytocin with promestriene in improving vaginal atrophy of Genitourinary Syndrome of Menopause (GSM). Methods: A total of 51 postmenopausal women with symptoms of GSM were evaluated. They were randomized into two groups: oxytocin (25 pati...

The cervical cancer screening recommendation suggests discontinuing screening for women over 65 years of age. Given that in many countries most of these women have never participated in an adequate screening program, the aim of this manuscript is to address some possible consequences of many current guidelines.

Melanocytic lesions on the genital area are rare and poorly documented; they occur more frequently on the vulva and less often on the perineum, pubic area, and male genitalia. Genital melanocytic nevi exhibit features similar to nevi occurring on other areas of the body; in addition, they display high clinical and histopathological variability and...

Objective: To compare the efficacy of fractional CO2 laser therapy with topical estrogen therapy for the treatment of postmenopausal genitourinary syndrome of menopause. Methods: We conducted a randomized controlled clinical trial involving 25 postmenopausal women. Participants were aged between 50 and 65 years with at least 1 year of amenorrhea...

The impact of artificial intelligence (AI) is already affecting cytopathology on diagnostic medicine, which offers a great perspective and many attractive approches for it. But, even though it may indeed improve accuracy and enhance many processes, the study aims to highlight some additional challenges and ethical issues that are relevant as well....

Aim: To evaluate cyclin-dependent kinase inhibitor 2A (CDKN2A) and cytokeratin 7 (CK7) expression in cervical intraepithelial neoplasia (CIN) formalin-fixed samples. Materials and Methods: Staining with antibody clones G175-405 for CDKN2A and OV-TL 12/30 for CK7 were evaluated and the detection of protein expressions were compared in 147 patients w...

Objective: Our objective was to verify the sensitivity and specificity of dual immunocytochemistry staining for p16 and Ki-67 in liquid-based samples (the "dual" assay) for cervical lesion screening, compared to biopsy findings and human papillomavirus (HPV) DNA molecular detection. Study design: Sensitivity, specificity, and positive (PPV) and...

Introduction: Diagnostic reproducibility and determination of prognostic factors in cervical intraepithelial neoplasias grades 1 and 2 are still relevant problems in the daily practice of gynecological histopathology. Objective: To correlate the value of morphological reclassification and of p16 immunoexpression in cervical intraepithelial neoplas...

Background: It is scarce in the literature studies regarding treatment and objective analysis of the survival chances of burned patients. Some investigations indicates the need for obtaining specific data to the population studied and characteristics such as social condition and nutritional status are suggested to be relevant to the patient's evolu...

Abstract Identifying factors, including human papillomavirus (HPV) genotypes, associated with abnormal anal cytology in HIV-infected women have implications for anal squamous cell cancer (SCC) prevention in HIV-infected women. Anal and cervical samples were collected for cytology, and tested for high-(HR-HPV) and low-risk HPV (LR-HPV) genotypes in...

To evaluate the relationship between microvascular density and the expression of vascular endothelial growth factor (VEGF) and KIT as possible markers of angiogenic stimulus in astrocytic tumors and correlate it with histopathological grading. We enrolled 99 surgical specimens of supratentorial astrocytic tumors for analysis of VEGF and KIT and sub...

Hemangiopericytomas are rare tumors arising from the proliferation of pericytes. They may be found in the lungs, bones, skull, deep soft tissue or limbs. The tumor has an unpredictable prognosis and when it affects the orbital region, may have an aggressive behavior, with high incidence of recurrence. We report a case of orbital hemangiopericytoma...

To present and evaluate the histological, anatomical and functional results of the McIndoe procedure, as modified by the application of oxidized cellulose (Surgicel™) in women with vaginal agenesis. Eleven patients with vaginal agenesis underwent vaginoplasty using a mould that had been wrapped with oxidized cellulose. The surgeries were performed...

Biliary hamartomas are hepatic lesions related to defects in the ductal plate and are part of the spectrum of adult polycystic disease. Microscopically, the lesions are small and consist of irregular bile ducts amidst a fibrous stroma. There are reports on the malignant transformation of biliary hamartomas, particularly on cholangiocarcinoma. Case...

OBJETIVOS: avaliou-se o tecido mamário de mulheres antes e depois de seis meses de terapia estroprogestativa combinada contínua (0,625 mg de estrogênios conjugados eqüinos associados a 2,5 mg de acetato de medroxiprogesterona). MÉTODOS: todas as pacientes foram avaliadas antes de se instituir o tratamento e consideradas aptas para este. Foram obtid...

PURPOSE: to analyze breast tissue of postmenopausal women before and after six months of continuous combined estrogen-progestin replacement therapy (0.625 mg conjugated equine estrogens associated with 2.5 mg medroxyprogesterone acetate). METHODS: all patients were evaluated before treatment and considered eligible to receive the drug. The material...

Reactive oxygen species are critical mediators of the early phase of ischemic (IR) injury. The contribution of antioxidants, such as N-acetyl-cysteine (NAC), in ameliorating the parenchymal lesions, inflammatory parameters, and functional variables in renal IR is still controversial. We studied the effect of NAC administration on renal injury induc...

Compared to other organs, the eyes are relatively infrequent sites of metastasis. In a landmark case series, Ferry and Font described 227 cases of carcinoma metastatic to the eyes. 1,2 Among these cases, only 28 (12%) were orbital metastases, most frequently from tumors of the breast, lung, and genitourinary tract; in this series, the diagnosis of...

O fibroistiocitoma maligno variante angiomatóide constitui entidade rara e geradora de controvérsia, especialmente quanto a sua histogênese. Apresenta como peculiaridades o acometimento preferencial da faixa etária pediátrica e o comportamento biológico indolente, tendo baixas taxas de metastatização. No presente caso, paciente feminina de 6 anos a...

Angiomatoid malignant fibrous histiocytoma is a rare and controversial entity, particularly as to its histogenesis. The tumor affects mostly the pediatric group, with an indolent clinical course and low rate of metastatization. In this report, the patient presented a lesion in the right foot and metastasis in an inguinal lymph node.

Hamartomas were first described by Albrecht in 1904, who defined them as tumor-like malformations in which there was abnormal blending of the normal components of an organ. The myoid hamartoma is a rare benign lesion of the breast and has an uncertain origin, possibly in the walls of the blood vessels, muscularis mammillae of the areolae, and mainl...
