Published: July 2015

A 53-year-old woman presented with a 3-month history of left inguinocrural and lumbar pain and anorexia with weight loss. No fever was reported. The patient had no prior pelvic surgery. Physical examination revealed a palpable nontender mass in the left groin area. There was no bloody or purulent discharge. Laboratory findings revealed inflammation with an increased C-reactive protein level (127 mg/L [1209 nmol/L]), leukocytosis (13 800/mm(3)), and microcytic anemia (hemoglobin level, 7.2 g/dL). Computed tomography (CT), fluorine 18 ((18)F) fluorodeoxyglucose (FDG) positron emission tomography (PET)/CT, and magnetic resonance (MR) imaging were performed.

Coal power plants adversely impact air pollution, but they also pose a risk to our water sources. Discharge wastewater from power plants may degrade the quality of nearby water bodies. This study evaluates the potential water-related environmental impacts of electricity generation at an ultra-supercritical coal power plant in Malaysia using the life cycle assessment method.

Background: Childhood cancer is not a high priority in health care financing for many countries, including in Ghana. Delayed care seeking and treatment abandonment, often due to the financial burden of care seeking to families, are common reasons for a relatively low overall survival (OS) in low-and middle-income countries. In this study, we analyzed the cost-effectiveness of extending health insurance coverage to children with Burkitt lymphoma (BL) in Ghana.

Background: Uncertainty in the diagnosis of lung nodules is a challenge for both patients and physicians. Artificial intelligence (AI) systems are increasingly being integrated into medical imaging to assist diagnostic procedures. However, the accuracy of AI systems in identifying and measuring lung nodules on chest computed tomography (CT) scans remains unclear, which requires further evaluation.

Objective: Endometriosis involves the growth of endometrium-like cells outside the uterus, affecting reproductive-aged women. Symptoms such as dysmenorrhea, pelvic pain, and infertility significantly impair quality of life. Among therapeutic options, progestogens have demonstrated efficacy in managing pain and reducing recurrence rates.

: This study investigated the potential chemopreventive role of proton pump inhibitor (PPI) use in relation to the occurrence of head and neck cancer (HNC) within a national cohort amid concerns of PPI overprescription. : From a cohort of 1,137,861 individuals and 219,673,817 medical claim records collected between 2005 and 2019, 1677 HNC patients were identified and matched 1:4 with 6708 controls after adjusting for covariates. Odds ratios (ORs) for PPI use and its duration in relation to HNC and its subsites were estimated using propensity score overlap-weighted multivariable logistic regression.
