A portrait of germline pathogenic variants in high and moderate penetrance breast cancer genes in Brazil.

Introduction: The prevalence of germline pathogenic/likely pathogenic variants (P/LP) in high and moderate penetrance (HMP) genes is approximately 7%-10% among breast cancer (BC) patients. The prevalence and spectrum of BC P/LP variants are affected by several factors. There are limited genetic data from Brazilian patients with BC.

Outpatient Palliative Care Program: Impact on Home Death Rate in Brazil.

While the positive impact of early palliative care on the quality of life of cancer patients is well established, there is a noticeable research gap in developing countries. This study sought to determine the impact of an outpatient palliative care (OPC) program on the location of death among patients in Brazil. This was a retrospective study including patients with cancer who died between January 2022 and December 2022 in 32 private cancer centers in Brazil.

Objective: To investigate the time spent in nsNSCLC molecular profile evaluation and its influence on clinical decisions.

Methods: nsNSCLC patients who underwent molecular testing in a private referral Brazilian center between November 2015 and February 2020 were identified.

Impact of the COVID-19 Pandemic on Cancer Staging: An Analysis of Patients With Breast Cancer From a Community Practice in Brazil.

Purpose: A nationwide lockdown was enforced in Brazil starting in March 2020 because of the COVID-19 pandemic when cancer screening activities were reduced. In this study, we evaluated the impact of the COVID-19 pandemic on breast cancer (BC) diagnosis.

Methods: We extracted data from the medical records of patients age older than 18 years who were diagnosed with BC and started treatment or follow-up in private oncology institutions in Brazil between 2018 and 2021.

Lessons From Implementing a Clinical Research Network in Brazil.

In this article, we discuss the strategy designed by a private oncology group to offer patients access to new technologies and treatments via a recently created research program, and we describe how the patient journey was the motivation for developing standard assistance flows and processes to integrate areas of care. The increase in Brazilians' life expectancy has raised the incidence of cancer, and it is now the second leading cause of death. Because it is a multifactorial disease, cancer treatment has several challenges.

Evaluation of KRAS Concomitant Mutations in Advanced Lung Adenocarcinoma Patients.

: One of the most frequently mutated oncogenes in cancer belongs to the Ras family of proto-oncogenes, which encode distinct key signaling events. RAS gain-of-function mutations are present in ~30% of all human cancers, with KRAS being the most frequently mutated isoform showing alterations in different cancer types including lung cancer. This study aimed to investigate the incidence of KRAS mutations, and concomitant mutations, in advanced non-small cell lung adenocarcinoma patients.

May Measurement Month 2019: an analysis of blood pressure screening results from Brazil.

The aim of this study is to describe the results of the May Month Measurement (MMM) campaign implemented in Brazil, in 2019. Questionnaire data were collected and three measures of blood pressure (BP) were performed. The sample consisted of 13 476 individuals, 58.

Independent real-world application of a clinical-grade automated prostate cancer detection system.

Artificial intelligence (AI)-based systems applied to histopathology whole-slide images have the potential to improve patient care through mitigation of challenges posed by diagnostic variability, histopathology caseload, and shortage of pathologists. We sought to define the performance of an AI-based automated prostate cancer detection system, Paige Prostate, when applied to independent real-world data. The algorithm was employed to classify slides into two categories: benign (no further review needed) or suspicious (additional histologic and/or immunohistochemical analysis required).

Determinants of COVID-19 Mortality in Patients With Cancer From a Community Oncology Practice in Brazil.

Purpose: The COVID-19 pandemic remains a public health emergency of global concern. Determinants of mortality in the general population are now clear, but specific data on patients with cancer remain limited, particularly in Latin America.

Materials And Methods: A longitudinal multicenter cohort study of patients with cancer and confirmed COVID-19 from Oncoclínicas community oncology practice in Brazil was conducted.

Pili Torti as a Sign of Eyebrow Involvement in Frontal Fibrosing Alopecia.

Frontal fibrosing alopecia (FFA) is a disease characterized by progressive band-like scarring alopecia involving the frontotemporal hairline and eyebrow hair loss. It affects mainly postmenopausal women. Trichoscopy features of FFA include absence of vellus hair, perifollicular erythema and scaling (peri-pilar casts), and absence of follicular openings.

Role of Patient and Disease Factors in Adjuvant Systemic Therapy Decision Making for Early-Stage, Operable Breast Cancer: Update of the ASCO Endorsement of the Cancer Care Ontario Guideline.

Purpose: To update the American Society of Clinical Oncology endorsement of the Cancer Care Ontario recommendations on the Role of Patient and Disease Factors in Adjuvant Systemic Therapy Decision Making for Early-Stage, Operable Breast Cancer.

Methods: Two phase III trials-the Trial Assigning Individualized Options for Treatment (TAILORx) in women with hormone receptor-positive, node-negative tumors and the Microarray in Node-Negative and 1 to 3 Positive Lymph Node Disease May Avoid Chemotherapy (MINDACT) trial-provided the evidence for this update.

Updated Recommendations: Shared decision making between clinicians and patients is appropriate for adjuvant systemic therapy for breast cancer.

Surgical versus conservative interventions for treating fractures of the middle third of the clavicle.

Background: Clavicle fractures are common, accounting for 2.6% to 4% of all fractures. Eighty per cent of clavicle fractures are located in the middle third of the clavicle.

Unusual skin manifestations associated with parvovirus B19 primary infection in children.

Parvovirus B19 is a DNA virus of the Parvoviridae family. We present four children with unusual exanthems associated with parvovirus infection: a purpuric periflexural pattern, a purpuric vasculitic pattern, and a combination of the two.

CARD14-associated papulosquamous eruption: A spectrum including features of psoriasis and pityriasis rubra pilaris.

Background: Heterozygous mutations in caspase recruitment domain family member 14 gene (CARD14) have been shown to be associated with psoriasis and familial pityriasis rubra pilaris (PRP). Many subjects with CARD14 mutations display features of both disorders, which can result in diagnostic uncertainty. In addition, these eruptions are often recalcitrant to conventional psoriasis therapies such as methotrexate, oral retinoids, and tumor necrosis factor-α inhibitors.

Infantile myofibromatosis.

Infantile myofibromatosis is a mesenchymal disorder characterized by the fibrous proliferation of the skin, bone, muscle and viscera. It is the most common fibrous tumor in childhood. We present a newborn with skin and bone disease without visceral involvement, who showed good response to vinblastine and methotrexate.

[4pp Mucocutaneous manifestations of methotrexate toxicity].

Methotrexate is an antimetabolite analog to folic acid that competitively inhibits the enzyme dihydrofolate reductase and thymidylate synthetase, essential for the synthesis of DNA and RNA. It is widely used in dermatology and its adverse effects on the skin and mucous membranes are varied, including mild and severe reactions. The appearance of erosions and skin ulcers as a manifestation of methotrexate cytotoxicity are quite infrequent.

Acral self-healing collodion baby: A case series.

Collodion baby is a term used to describe a phenotype characterized by the presence of a tight, translucent membrane that covers the entire skin at birth. This membrane usually sheds around 10 to 14 days and reveals the underlying disease (mainly different types of Recessive Ichthyosis or other infrequent disorders). A rare variant of this phenotype is known as acral self-healing collodion baby whereby the patients are born with the typical membrane but limited to the hands and feet only, and after it sheds, the skin appears completely normal.

Ichthyosis follicularis with alopecia and photophobia syndrome (IFAP): A Case Report.

IFAP syndrome is a rare autosomal recessive X-linked disease characterized by the triad of alopecia universalis, severe photophobia, and follicular ichthyosis. It is caused by loss of function of the gene MBTPS2. Its severity varies and there are only a few reports in the literature.

Kaposi's varicelliform eruption: A case series.

Kaposi's varicelliform eruption is a rare and potentially fatal viral infection caused mainly by reactivation of herpes simplex virus. It concomitantly occurs with pre-existing skin conditions, mostly atopic dermatitis, so it is predominately found in children. We present a case series that includes four adults, familial cases, and previously healthy patients.

Male and couple fertility impairment due to HPV-DNA sperm infection: update on molecular mechanism and clinical impact--systematic review.

Recent evidences identify Human Papillomavirus (HPV) sperm infection as a possible cause of male and couple infertility. It acts through different mechanisms at various steps of human conception and early gestational development. We performed a systematic review to assess the role of HPV semen infection on male and couple infertility.

Infantile perianal protrusion.

Infantile perianal protrusion is characterized by a skin fold located in the perianal area. It is a relatively recent reported condition and affects both infants and prepubertal children with a clear female predominance. Three types are recognized: constitutional/congenital, acquired, and associated with lichen sclerosus et atrophicus.
