Verrucae vulgaris are infectious keratotic lesions caused by the human papillomavirus (HPV), frequently impairing an individual's quality of life, mainly when situated on the facial region. Verruca vulgaris constitutes a prevalent dermatological issue with diverse repercussions for those affected. The interaction among HPV, the immune system, and treatment methods requires a sophisticated comprehension of this illness.

Article Synopsis
  • Elevated mammographic density (MD) is a significant risk factor for breast cancer, and this study investigates how factors like childbirth, age at first birth, and breastfeeding relate to MD in a large group of women across different countries.
  • The research analyzed data from 11,755 women aged 35-85 years, focusing on how factors such as the number of births and the timing of the first birth influence measurements of MD.
  • The findings suggest that having more children decreases MD, while older age at first birth is linked to higher MD, particularly in post-menopausal women, highlighting the complex relationships between reproductive factors and breast density.

Background: Diagnostic radiology residents in low- and middle-income countries (LMICs) may have to provide significant contributions to the clinical workload before the completion of their residency training. Because of time constraints inherent to the delivery of acute care, some of the most clinically impactful diagnostic radiology errors arise from the use of Computed Tomography (CT) in the management of acutely ill patients. As a result, it is paramount to ensure that radiology trainees reach adequate skill levels prior to assuming independent on-call responsibilities.

The protozoan parasite Cryptosporidium is a leading cause of diarrhea in young children. The parasite's life cycle involves a coordinated and timely progression from asexual to sexual stages, leading to the formation of the transmissible oocyst. Underlying molecular signaling mechanisms orchestrating sexual development are not known.

Article Synopsis
  • - The study investigates the potential link between adenoidectomy (a surgical procedure to remove adenoid tissue) and the risk of developing Inflammatory Bowel Disease (IBD), specifically Crohn's disease (CD) and ulcerative colitis (UC) among children, in the context of the role of gut-associated lymphoid tissue in immune modulation.
  • - A pooled meta-analysis was conducted between multiple observational studies, and results showed a significant association between appendicectomy and CD, while there was a notable association between tonsillectomy and CD as well, but no significant link to UC from appendicectomy.
  • - The findings suggest that while removing adenoid or tonsil tissue may be linked to an increased risk of CD

Purpose: This guideline provides evidence-based recommendations on appropriate indications and techniques for partial breast irradiation (PBI) for patients with early-stage invasive breast cancer and ductal carcinoma in situ.

Methods: ASTRO convened a task force to address 4 key questions focused on the appropriate indications and techniques for PBI as an alternative to whole breast irradiation (WBI) to result in similar rates of ipsilateral breast recurrence (IBR) and toxicity outcomes. Also addressed were aspects related to the technical delivery of PBI, including dose-fractionation regimens, target volumes, and treatment parameters for different PBI techniques.

Article Synopsis
  • This study investigates the impact of COVID-19 on female patients with breast cancer, particularly focusing on underrepresented racial/ethnic populations from March 2020 to June 2021 in the US.
  • The analysis included 1,383 patients, revealing that older age and certain racial/ethnic groups (such as Black and Asian American/Pacific Islanders) showed higher odds of severe COVID-19 outcomes.
  • Key findings noted that factors like worse performance status, pre-existing health conditions, and active cancer significantly contributed to increased severity, while variables like Hispanic ethnicity and anti-cancer therapy type did not impact outcomes as much.

Background: HER2 mutations are targetable alterations in patients with hormone receptor-positive (HR+) metastatic breast cancer (MBC). In the SUMMIT basket study, patients with HER2-mutant MBC received neratinib monotherapy, neratinib + fulvestrant, or neratinib + fulvestrant + trastuzumab (N + F + T). We report results from 71 patients with HR+, HER2-mutant MBC, including 21 (seven in each arm) from a randomized substudy of fulvestrant versus fulvestrant + trastuzumab (F + T) versus N + F + T.

Purpose: A 3-biomarker homologous recombination deficiency (HRD) score is a key component of a currently FDA-approved companion diagnostic assay to identify HRD in patients with ovarian cancer using a threshold score of ≥ 42, though recent studies have explored the utility of a lower threshold (GIS ≥ 33). The present study evaluated whether the ovarian cancer thresholds may also be appropriate for major breast cancer subtypes by comparing the genomic instability score (GIS) distributions of BRCA1/2-deficient estrogen receptor-positive breast cancer (ER + BC) and triple-negative breast cancer (TNBC) to the GIS distribution of BRCA1/2-deficient ovarian cancer.

Methods: Ovarian cancer and breast cancer (ER + BC and TNBC) tumors from ten study cohorts were sequenced to identify pathogenic BRCA1/2 mutations, and GIS was calculated using a previously described algorithm.

Article Synopsis
  • The study investigates the impact of COVID-19 on female breast cancer patients using a large U.S. registry during 2020-2021, focusing on underrepresented racial/ethnic populations.
  • Key findings show that older age, being Black, Asian American/Pacific Islander, and having worse overall health significantly increase the severity of COVID-19 in these patients.
  • The overall hospitalization rate was 37% and mortality rate 9%, but these rates varied depending on the active status of breast cancer in patients.

The protozoan parasite is a leading cause of diarrheal disease (cryptosporidiosis) and death in young children. Cryptosporidiosis can be life-threatening in individuals with weak immunity such as HIV/AIDS patients and organ transplant recipients. There is currently no effective drug to treat cryptosporidiosis in the pediatric and immunocompromised population.

Poly (adenosine diphosphate-ribose) polymerase (PARP) inhibitor monotherapy in germline BRCA1 and BRCA2 mutation-associated metastatic breast cancer is a well-tolerated and an effective therapeutic strategy, however, the durability of response can be limited. Checkpoint inhibitors targeting the PD-1/PD-L1 axis as monotherapy in metastatic triple-negative breast cancer (mTNBC) have a limited role due to low response rates, but are capable of long, durable responses. Combination PARP inhibition with checkpoint blockade is an emerging area of investigation with potential synergy to produce robust responses with durability.

Ethnopharmacological Relevance: Chikungunya disease (CHIKD) is caused by the alphavirus, chikungunya virus (CHIKV) and is characterized by acute fever and joint inflammation; the inflammation continues even after clearance of the virus from the system, persisting for several months to years. Currently, there are no modern medicines/vaccines available for its treatment and use of over-the-counter anti-inflammatory generic medicines to relieve symptoms is generally practiced. In India, Indian traditional medicines hold a lot of promise to treat this infection and are routinely used during outbreaks.
