Insights

A rare case of Candida parapsilosis osteomyelitis in the shoulder is presented. This fungal infection, often linked to medical devices or drug use, highlights the importance of considering fungi in bone infections.

Area of Science:

  • Infectious Diseases
  • Mycology
  • Orthopedics

Background:

  • Candida species are typically commensal organisms with low virulence.
  • Invasive candidal infections are increasing due to factors like intravenous drug use and central venous catheters.
  • Osteomyelitis caused by Candida species is exceptionally rare.

Purpose of the Study:

  • To report a rare case of Candida parapsilosis osteomyelitis.
  • To discuss the diagnostic challenges and clinical presentation of fungal osteomyelitis.
  • To emphasize the importance of considering fungal pathogens in specific patient populations.

Main Methods:

  • Clinical presentation of a 73-year-old man with right shoulder pain.
  • Diagnostic imaging including ultrasonography, MRI, and bone scan.
  • Ultrasonographically guided joint aspiration for fluid analysis, culture, and staining.

Main Results:

  • Imaging suggested osteomyelitis of the right acromioclavicular joint.
  • Pathologic findings revealed acute and chronic inflammation.
  • Tissue culture and staining identified Candida parapsilosis as the causative agent.

Conclusions:

  • Candida parapsilosis can cause rare but serious bone infections.
  • Early and accurate diagnosis is crucial for effective treatment of fungal osteomyelitis.
  • Clinical suspicion should be raised in patients with risk factors for invasive fungal infections.

Muscles of the Shoulder01:23

Muscles of the Shoulder

The muscles surrounding the shoulder girdle, including the clavicle and scapula, primarily stabilize the scapula. This stable base allows other muscles to move the humerus effectively. Scapular movements often mirror those of the humerus and extend its range of motion. For instance, raising the arm above the head would not be feasible without simultaneous upward rotation of the scapula.

The anterior thoracic muscles include the serratus anterior, subclavius, and...
Acute Pharyngitis01:30

Acute Pharyngitis

Introduction
Acute pharyngitis is the inflammation of the back of the throat (pharynx), commonly resulting in a sore throat. It is a frequently encountered condition that prompts individuals to seek medical advice.
Classification
Acute pharyngitis can be categorized based on its underlying cause:
Staphylococcal Skin Infections01:29

Staphylococcal Skin Infections

Staphylococcus aureus is a Gram-positive coccus that resides harmlessly on the skin and mucous membranes of healthy individuals. When the skin barrier is breached, it can shift from a commensal to an opportunistic pathogen. This transition is facilitated by surface adhesins, such as clumping factor B and S. aureus surface protein G (SasG), which bind to structural proteins, including loricrin and cytokeratin, in the damaged epidermis. Protein A, another key factor, binds the Fc region of...

Functional Classification of Joints

Functional Classification of Joints
The functional classification of joints is determined by the amount of mobility between the adjacent bones. Joints are functionally classified as a synarthrosis or immobile joint, an amphiarthrosis or slightly moveable joint, or as a diarthrosis, a freely moveable joint. Fibrous and cartilaginous joints can be functionally classified as either synarthroses  or amphiarthroses, whereas all synovial joints are classified as diarthroses.
Synarthrosis

Structural Joints: Synovial Joints01:16

Structural Joints: Synovial Joints

Synovial joints are the most common type of joint in the body. A key structural characteristic for a synovial joint is the presence of a joint cavity. This fluid-filled space is where the articulating surfaces of the bones contact each other. Also, unlike fibrous or cartilaginous joints, the articulating bone surfaces at a synovial joint are not directly connected to each other with fibrous connective tissue or cartilage. This gives the bones of a synovial joint the ability to move smoothly...
Infectious Diseases and Their Occurrence01:28

Infectious Diseases and Their Occurrence

Infectious diseases appear in populations through various transmission patterns, influenced by pathogen characteristics, population immunity, environmental conditions, and social behavior. Understanding these patterns is essential for effective public health surveillance and intervention. These categories—sporadic, outbreak, epidemic, pandemic, and endemic—help frame the nature and scope of disease events.Sporadic diseases occur irregularly and infrequently, without a predictable temporal or...
