Liver and Renal Function Evaluation

Introduction to Evaluation Tests

Morning urine and serum osmolality tests are used to evaluate symptoms suggesting endocrine disorders, as recommended by the American Society of Clinical Pathology 1
Gynecomastia is defined as actual glandular breast tissue enlargement, while pseudogynecomastia is fatty tissue deposition without glandular proliferation, as defined by the American College of Radiology 2

Most cases of gynecomastia can be diagnosed based on clinical findings without imaging, according to the American College of Radiology 2
Diagnostic mammography or digital breast tomosynthesis (DBT) is recommended as the initial imaging study for males ≥25 years with breast pain, according to the American College of Radiology 2
A bilateral mammogram is routinely performed to assess symmetry and detect contralateral abnormalities, with a negative predictive value of 99-100% 2
Nipple discharge or retraction and axillary adenopathy are concerning features that warrant further evaluation 2
Ultrasound is indicated when the mammogram is indeterminate or suspicious, and assists in lesion characterization and guides biopsy, with a sensitivity of 88.9% and specificity of 95.3% 2
Core needle biopsy is recommended for suspicious or indeterminate findings on imaging, and for masses that cannot be confidently classified as benign, with a high degree of safety and effectiveness 2

Spironolactone is the medication most strongly associated with gynecomastia, with approximately 10% of male patients developing this side effect, as seen in the RALES trial 3
Eplerenone is a lower risk alternative to spironolactone, recommended by the American Heart Association 3, 4
Beta blockers, such as metoprolol and carvedilol, are less commonly associated with gynecomastia 5, 6
Other medications, including hormone replacement therapies, antipsychotics, 5-α reductase inhibitors, and spironolactone, can increase the risk of mastodynia and gynecomastia, according to the American College of Radiology, American Psychiatric Association, American Urological Association, and American College of Cardiology/American Heart Association 7, 8, 9, 10, 11
Advanced age, liver disease, renal insufficiency, obesity, and concurrent use of multiple medications that can cause gynecomastia increase the risk of developing gynecomastia 3, 6
Pre-existing hormonal imbalances also increase the risk of gynecomastia 3, 6

Alternative treatments to spironolactone, such as eplerenone, can minimize the risk of gynecomastia, with a recommended initial dose of 25-50 mg daily and a maintenance dose of 50-100 mg daily, according to the American College of Cardiology/American Heart Association 10, 12, 13
Surgical options, such as liposuction, direct excision, or combined approaches, may be considered for long-standing gynecomastia (>12-24 months) that doesn't respond to medication changes, according to the American Society of Plastic Surgeons 8
Acetaminophen is recommended as first-line analgesic in elderly patients with mild to moderate pain, and NSAIDs can be used if there are no contraindications, with caution due to potential GI, renal, and cardiovascular risks, according to the American Geriatrics Society 14
A multimodal analgesia approach can minimize opioid requirements for severe pain, as suggested by the World Journal of Emergency Surgery 15
Regular monitoring for adverse effects of medications, particularly NSAIDs and opioids, is recommended, according to the American Geriatrics Society 14
Venous thromboembolism prophylaxis should be considered in high-risk patients with limited mobility, as suggested by the World Journal of Emergency Surgery 15
Potential long-term effects of untreated hyperprolactinemia, including bone mineral density loss and increased risk of breast cancer, should be considered, according to the National Institute of Mental Health and the American Cancer Society 8
