Accessory Structures of the Skin: Sweat Glands01:20

Accessory Structures of the Skin: Sweat Glands

4.7K
Sweat glands or sudoriferous glands are one of the important accessory structures of the skin. They are small, coiled tubular structures located in the dermis, the middle layer of the skin. Sweat glands are responsible for producing and secreting sweat, a watery fluid that helps regulate body temperature and excrete waste products.
Sweat glands are classified as merocrine glands; that is, the secretions are excreted by exocytosis through a duct without affecting the cells of the gland. There...

Procedural Guide for Assessing Axillary Body Temperature using a Digital Thermometer:
Step 1: Perform hand hygiene and put on clean gloves to maintain infection control and prevent cross-contamination.
Step 2: Prepare the patient by explaining the procedure to ensure understanding and cooperation. Ensure privacy, expose the axilla, and inform the patient that minimal movement is crucial for an accurate reading.
Step 3: Adjust the patient’s clothing to expose only the axilla. It minimizes...

Increased Body Temperature

7.7K
A body temperature above  38°C  (100.4 °F) is known as fever or pyrexia, and a person with fever is termed 'febrile.' Typically, the hypothalamus, a part of the brain that acts as the body's thermostat, regulates body temperature through a thermoregulatory setpoint. It receives signals from cold and warm thermal receptors throughout the body and adjusts the body's temperature accordingly. Fever occurs when this hypothalamic setpoint is altered, usually in...

Body Temperature01:25

Body Temperature

5.4K
The body's temperature, measured in degrees, is determined by the balance between heat production and dissipation to the surrounding environment. For instance, if exercising vigorously, the body will produce more heat, causing sweat and dissipating that heat. Despite extreme environmental conditions and physical exertion, the human temperature-control system maintains a constant core body temperature (the temperature of deep tissues, which are the tissues located beneath the skin and other...

Body Temperature01:07

Body Temperature

1.9K
Body temperature reflects the equilibrium between heat production and heat loss within the body. Most heat is generated by metabolically active tissues, particularly the liver, heart, brain, kidneys, and endocrine organs. At rest, skeletal muscles contribute 20–30% of total heat production, but during vigorous exercise, this can increase up to 30–40 times.
The average body temperature is approximately 37°C (98.6°F) and typically ranges from 36.1–37.2°C...

Methods of reducing fever01:22

Methods of reducing fever

1.6K
The signs and symptoms of fever include hot and dry skin, flushed face, thirst, muscle aches, anorexia, headache, tachycardia, tachypnea, and fatigue. Elevated body temperature is reduced using two methods: pharmacological and nonpharmacological. Proper identification and treatment of the root cause of a fever is of utmost importance.

Area of Science:

  • Pediatric Dermatology
  • Rare Genetic Disorders

Background:

  • Chromhidrosis is a rare condition characterized by the production of colored sweat.
  • The exact etiology of chromhidrosis can vary, necessitating thorough investigation.

Observation:

  • A toddler presented with clinically apparent colored sweat.
  • Diagnostic evaluation included a skin biopsy to confirm chromhidrosis.

Findings:

  • The skin biopsy confirmed the diagnosis of chromhidrosis in the toddler.
  • Given the patient's young age, no active treatment was initiated.

Implications:

  • This case underscores the importance of appropriate diagnostic investigations for identifying the causes of colored sweat.
  • Understanding the benign nature of chromhidrosis is crucial for parental counseling and management.
