Muir-Torre Syndrome: A Case Report and a Literature Review of Genetic Insights and Cancer Surveillance.

Muir-Torre syndrome (MTS) is a rare autosomal dominant genetic disorder that manifests through the co-occurrence of sebaceous skin tumors and internal malignancies, primarily due to mutations in mismatch repair (MMR) genes such as MSH2, MLH1, and MSH6. This paper presents a detailed case report of a 57-year-old female diagnosed with MTS, highlighting her extensive medical history and the critical role of genetic testing and multidisciplinary management. The patient's dermatological and oncological assessments revealed multiple sebaceous carcinomas and recurrent urothelial carcinoma, confirmed by a pathogenic MSH2 mutation. Through comprehensive preventive surgeries and rigorous follow-up, this case underscores the necessity of proactive cancer surveillance. The discussion integrates findings from key genetic studies and emphasizes the importance of immunohistochemistry in diagnosis. Recommendations for clinical practice include routine genetic testing, stringent surveillance, and multidisciplinary management, underscoring the need for ongoing research to understand better and manage this complex syndrome.

Chemotherapy and Metabolic Syndrome: A Comprehensive Review of Molecular Pathways and Clinical Outcomes.

Cancer therapies, notably chemotherapy, have significantly improved survival rates and quality of life for many patients. However, chemotherapy's cytotoxic effects also impact normal cells, leading to adverse effects, including metabolic disturbances. This paper explores the link between chemotherapy and metabolic syndrome, a cluster of metabolic abnormalities that increase the risk of cardiovascular diseases and type 2 diabetes. Understanding the predictors, such as specific chemotherapy regimens, patient characteristics, comorbid conditions, lifestyle factors, and genetic variations, is crucial for formulating personalized care plans and preventive strategies. Research indicates that older age, female gender, pre-existing diabetes, and baseline obesity are significant predictors of metabolic syndrome in cancer patients. Chemotherapy-induced molecular changes, including insulin resistance, dyslipidemia, chronic inflammation, oxidative stress, and tissue fibrosis, contribute to the development of this syndrome. Effective management strategies require a multidisciplinary approach, incorporating lifestyle interventions, pharmacological treatments, and regular monitoring. This paper underscores the importance of personalized medicine in mitigating the risks associated with metabolic syndrome and improving long-term health outcomes for cancer survivors. Future research directions include longitudinal studies to track metabolic health over time, mechanistic studies to uncover the molecular pathways involved, and the development of integrative therapies. By adopting comprehensive care models, healthcare providers can enhance the overall quality of life for cancer survivors, addressing both cancer and metabolic health challenges.

Aryl Hydrocarbon Receptor Signaling in Prostate Cancer Therapy: A Review of Implications for Anti-androgen Treatment Strategies and Resistance.

Prostate cancer is a leading cause of cancer-related morbidity and mortality in men, frequently exhibiting resistance to conventional anti-androgen therapies. This review investigates the emerging significance of the aryl hydrocarbon receptor (AhR) in prostate cancer, focusing on its role in modulating androgen receptor (AR) signaling and its potential as a therapeutic target. AhR, traditionally known for detoxifying harmful compounds, has been increasingly recognized for its dual capacity to either enhance or inhibit AR activity based on cellular context and specific coactivators. Furthermore, AhR influences tumor progression independently of AR by regulating genes involved in cell cycle control and apoptosis. This narrative review synthesizes current research on AhR's multifaceted roles in prostate cancer, evaluates its potential as a biomarker, and discusses the therapeutic implications of targeting AhR, particularly for hormone-refractory prostate cancer. Our findings underscore the necessity for personalized AhR-targeted therapies and advocate for continued clinical research to fully leverage AhR's therapeutic potential.

A Rare Presentation of Systemic Lupus Erythematosus (SLE) With Hemoptysis and Hematuria: A Case Report.

Systemic lupus erythematosus (SLE) is an autoimmune disease characterized by type II and type III hypersensitivity reactions that affect multiple organs, including the joints, heart, lungs, brain, skin, and kidneys. Patients with SLE can experience a range of symptoms, ranging from fever and joint pain to a distinctive butterfly facial rash. Severe complications may encompass conditions such as diffuse alveolar hemorrhage (DAH), pulmonary hypertension, and lupus nephritis, among others. Among them, DAH, a critical pulmonary complication in SLE, involves bleeding from interstitial capillaries and alveoli due to immune complex damage. This case report describes a patient who was initially misdiagnosed but later confirmed to have SLE. The patient presented with persistent symptoms, including cough, dyspnea, and fever, over two weeks and subsequently developed hematuria and hemoptysis within the last two days. The progression of symptoms led to an acute exacerbation, resulting in her admission to the emergency department. Subsequent evaluations confirmed the diagnosis of lupus nephritis and DAH. This case highlights the importance of considering SLE in the differential diagnosis of unexplained systemic symptoms and underscores the urgent need for medical intervention in DAH to substantially reduce mortality.

Determinants of digital eye strain among university students in a district of India: a cross-sectional study.

Aim: Digital device usage, especially during the pandemic, has catapulted into a new age problem, the computer vision syndrome. This study aimed to quantify the prevalence and determinants of digital eye strain (DES). Subject and Methods: A total of 345 university students in India were surveyed in June-July 2022, by a validated tool, the Computer Vision Syndrome Questionnaire (CVS-Q) © in this cross-sectional study. According to American Optometric Association, digital eye strain and computer vision syndrome are synonyms. Non-parametric tests of medians were used to compare the median DES scores, Chi square test to compare categorical variables, and binary logistic regression to find the determinants of DES. Results: The average age of the study participants was 21.0 ± 2.2 years, ranging between 18-26 years with 52.8% females and 47.2% males. The prevalence of DES was 45.5% (CI 95% = 40.2%-50.8%). Any existing eye disease (p-value = 0.000, OR = 0.41, 95% CI = 0.26-0.65), average daily screen time (p-value = 0.001, OR = 1.61, 95% CI = 1.22-2.13) and using gadgets in the dark (p-value = 0.000, OR = 0.37, 95% CI = 0.23-0.61) were significant determinants of the same. Conclusion: Framing guidelines limiting the hours allotted for online classes for university students are imperative, with promotion of ergonomic practices for digital device usage such as blue light filters and night mode on devices.
