Endocarditis II: Clinical Features of Infective Endocarditis

14
Endocarditis can present various clinical features depending on the causative organism and the patient's underlying health conditions. Initially, the clinical features of infective endocarditis develop gradually, presenting with nonspecific symptoms that can be easily mistaken for other illnesses.General SymptomsEarly symptoms of infective endocarditis are fever, chills, weakness, malaise, fatigue, and weight loss. These symptoms reflect the systemic nature of the infection and the body's...

Changes in Skin Color: Clinical Perspectives

2.0K
The first thing a clinician sees is the skin, so the examination of the skin should be part of any thorough physical examination. Most skin disorders are relatively benign, but a few, including melanomas, can be fatal if untreated. A couple of the more noticeable disorders, albinism and vitiligo, affect the appearance of the skin and its accessory organs.
Albinism
Albinism is a genetic disorder that affects (completely or partially) the coloring of skin, hair, and eyes. The defect is primarily...

Skin Cancer01:30

Skin Cancer

4.2K
Skin cancer is a type of cancer that occurs when there is an abnormal growth of skin cells, usually triggered by damage to the DNA within the skin cells. It is primarily caused by exposure to ultraviolet (UV) radiation from the sun or artificial sources like tanning beds. Skin cancer is the most common type of cancer worldwide, and its incidence continues to rise.
Basal Cell Carcinoma (BCC): BCC is the most common type of skin cancer, accounting for about 80% of cases. It typically develops in...

Papillary Dermis01:11

Papillary Dermis

3.0K
Dermis
The dermis might be considered the "core" of the integumentary system, as distinct from the epidermis and hypodermis. It contains blood and lymph vessels, nerves, and other structures, such as hair follicles and sweat glands. The dermis is made of two layers of connective tissue that comprise an interconnected mesh of elastin and collagenous fibers, produced by fibroblasts.
Papillary Layer
The papillary layer is made of loose, areolar connective tissue, which means the collagen...

Pigmentation01:19

Pigmentation

2.5K
The color of the skin is influenced by a number of pigments, including melanin, carotene, and hemoglobin. Recall that melanin is produced by cells called melanocytes, which are found scattered throughout the stratum basale of the epidermis. The melanin is transferred to the keratinocytes via melanosomes.
Melanin occurs in two primary forms: eumelanin that provides black and brown pigment and pheomelanin that provides red color. Dark-skinned individuals produce more melanin than those with pale...

Assessment of the Cardiovascular System III: Palpation

383
Palpation involves feeling the body to evaluate texture, size, consistency, and tenderness for assessing cardiovascular health. The following steps are organized in a head-to-toe order:
Jugular Venous Pressure (JVP) Measurement
Position the patient at a thirty- to forty-five-degree angle or in a semi-fowler's position. Look for the highest point of pulsation in the internal jugular vein and measure the vertical distance to the angle of Loius or sternal angle. A normal JVP is 3-4 cm above...

Area of Science:

  • Dermatology
  • Internal Medicine

Background:

  • Figurate erythemas, a term introduced by T. Colcott Fox in 1889, describe skin conditions with annular, circinate, or arciform patterns.
  • Key types include erythema annulare centrifugum, erythema marginatum, erythema gyratum repens, erythema migrans, erythema chronicum migrans, and pediatric annular erythemas.

Purpose of the Study:

  • To review the clinical patterns, associations, and diagnostic criteria of various figurate erythemas.
  • To highlight the importance of identifying underlying causes for effective treatment.

Main Methods:

  • Literature review of clinical presentations and associations of different figurate erythemas.
  • Analysis of diagnostic criteria and treatment approaches for each type.

Main Results:

  • Erythema annulare centrifugum can be linked to infections or drugs.
  • Erythema marginatum is a criterion for acute rheumatic fever but also associated with other conditions.
  • Erythema gyratum repens is a paraneoplastic sign, particularly with lung cancer.
  • Erythema chronicum migrans signifies Borrelia infection.
  • Pediatric annular erythemas encompass a range of infantile dermatoses.

Conclusions:

  • Figurate erythemas present diverse clinical patterns and etiologies.
  • Accurate diagnosis and etiological treatment are crucial for managing these conditions.
  • Prompt identification of underlying diseases, such as infections or malignancies, ensures therapeutic success.
