Summary
Gynaecomastia, a benign breast enlargement in males, can be drug-induced. This case highlights a rare instance of gynaecomastia linked to the highly active antiretroviral therapy (HAART) regimen known as TLE.
Area of Science:
- Endocrinology
- Pharmacology
- Infectious Diseases
Background:
- Gynaecomastia is benign glandular enlargement of the male breast.
- Numerous medications are known to cause gynaecomastia.
- The highly active antiretroviral therapy (HAART) regimen, TLE, is rarely associated with this condition.
Observation:
- A 42-year-old male, diagnosed as HIV-positive for 10 years, was initiated on the TLE regimen.
- The patient subsequently developed gynaecomastia over an 11-month period.
Findings:
- This case report documents a rare instance of gynaecomastia in an HIV-positive patient receiving HAART.
- The TLE regimen is implicated as a potential cause of drug-induced gynaecomastia.
Implications:
- Clinicians should consider TLE as a potential cause of gynaecomastia in HIV-positive patients.
- Further research may be warranted to elucidate the mechanism of TLE-induced gynaecomastia.

Signs of Puberty
1.3K
Puberty is a critical phase, typically beginning between the ages of 8 and 13 in girls and 9 and 14 in boys, though timing can vary based on genetics, environmental factors, and overall health. This period is characterized by the development of secondary sexual characteristics and the attainment of reproductive potential. Endocrine changes underpin puberty, with hormonal surges of Luteinizing Hormone (LH) and Follicle-Stimulating Hormone (FSH) instigated by Gonadotropin-Releasing Hormone (GnRH)...

Menopause
3.5K
Menopause, a natural biological process marking the end of a woman's fertility, typically occurs between the fifth and sixth decade of life. This phase is characterized by the exhaustion of the ovarian follicle pool, leading to less responsive ovaries despite the high levels of Follicle Stimulating Hormone (FSH) and Luteinizing Hormone (LH). The consequential decrease in estrogen production results in symptoms like hot flashes, heavy sweating, headaches, hair loss, muscle pains, vaginal...

Accessory Structures of the Skin: Hair Growth and Types
2.2K
Hair growth begins with the production of keratinocytes by the basal cells of the hair bulb. As new cells are deposited at the hair bulb, the hair shaft is pushed through the follicle toward the surface. Keratinization is completed as the cells are pushed to the skin surface to form the shaft of hair that is externally visible. The external hair is completely dead and composed entirely of keratin. Hair can be cut or shaven without damaging the hair structure because the cut is superficial. Most...

Accessory Structures of the Skin: Hair and Hair Follicles
4.1K
Hair and hair follicles are integral components of the integumentary system. Hair is a filamentous structure composed mainly of a protein called keratin. It is found on the surface of the skin throughout the body, except for areas such as the palms of the hands and soles of the feet.
Hair is a keratinous filament growing out of the epidermis. It is primarily made of dead, keratinized cells. Hair strands originate at the epidermal penetration called the hair follicle. The hair shaft is the part...

Cardiomyopathy III: Hypertrophic Cardiomyopathy
325
Hypertrophic cardiomyopathy, or HCM, is an autosomal dominant genetic disorder characterized by asymmetric left ventricular hypertrophy without ventricular dilation. It is more common in men and is typically diagnosed in young, athletic adults.EtiologyHCM is primarily genetic and is caused by mutations in genes encoding sarcomeric proteins. Researchers have identified over 1400 mutations across at least 11 different genes. Among these, the most frequently occurring mutations are found in the...

Heart Failure III: Clinical Manifestations
397
Heart failure (HF) manifests primarily as dyspnea, fatigue, and fluid retention, resulting in peripheral and pulmonary edema. Symptoms may vary depending on which ventricle is more affected, left or right.Left-Sided Heart FailureAlso known as left ventricular failure, this condition results from the left ventricle's inability to fill or eject sufficient blood into the systemic circulation. It leads to pulmonary congestion, which occurs when the left ventricle fails to eject blood effectively...
