Hand hygiene01:23

Hand hygiene

Asepsis is the practice of preventing or breaking the chain of infection. The nurse employs aseptic techniques to prevent the spread of microorganisms and reduce the risk of diseases. Hand hygiene is the cornerstone of aseptic techniques and is classified into medical and surgical asepsis. Medical asepsis includes hand hygiene and the use of gloves. Surgical asepsis, or the sterile technique, refers to practices that render and keep objects and areas free of microorganisms.

Handwashing II: Pre-procedure and Initial Procedure Steps

The pre-procedure steps of handwashing include removing jewelry and rolling up sleeves. However, many organizations allow staff to wear wedding rings.
The hand washing procedure itself includes the following steps. First, cover cuts, if any, on hands with a waterproof dressing. Cuts and abrasions can become contaminated with bacteria hindering the ability to clean the area thoroughly. In addition, repeated hand washing can worsen an injury.  The nails must be short and clean, without nail paint...

Healthcare Associated Infections II: Preventive Measures

Essential infection prevention measures are based on the knowledge of the infection chain, the modes of transmission in healthcare settings, and the use of the best practices in all healthcare settings. Compulsory public reporting of healthcare-associated infection rates is needed to allow individuals and the community to make informed choices regarding selecting a healthcare facility.
The best practices for preventing healthcare-associated infections include hand hygiene, patient risk...
Sources of Food Contamination01:29

Sources of Food Contamination

Contamination of food by microbial agents and natural toxins poses significant risks to public health. These hazards can be introduced at various points across the food supply chain, ranging from environmental sources to processing and storage stages. Understanding these contamination pathways is critical for developing strategies to ensure food safety.Seafood is particularly vulnerable to contamination through both environmental exposure and microbial colonization. Toxins from harmful algal...
Clinical Significance of Antibiotic Resistance01:25

Clinical Significance of Antibiotic Resistance

Methicillin-resistant Staphylococcus aureus (MRSA) presents a critical public health threat, arising from its capacity to resist β-lactam antibiotics due to acquisition of the mecA gene within the staphylococcal cassette chromosome mec (SCCmec). This gene encodes penicillin-binding protein 2a (PBP2a), which impairs binding efficacy of methicillin and other β-lactams. MRSA has evolved into distinct clonal lineages impacting humans and animals alike, reinforcing its significance within the One...

Area of Science:

  • Infectious Diseases
  • Dermatology
  • Orthopedic Surgery

Background:

  • Mycobacterium marinum infections, often acquired from aquatic environments, can cause persistent tenosynovitis.
  • Sushi chefs are at risk due to potential exposure to contaminated seafood and fish tanks.
  • Xanthogranulomatous reactions can mimic other inflammatory or neoplastic conditions.

Purpose of the Study:

  • To report a case of Mycobacterium marinum infection presenting as tenosynovitis in a sushi chef.
  • To highlight the diagnostic challenges and treatment outcomes for this rare occupational hazard.

Main Methods:

  • Clinical presentation of a sushi chef with chronic finger and wrist pain and swelling.
  • Diagnostic biopsy revealing xanthogranulomatous inflammation and positive cultures for Mycobacterium marinum.
  • Therapeutic regimen including a combination of antibiotics (minocycline, clarithromycin, ethambutol) and radical synovectomy.

Main Results:

  • Successful treatment of Mycobacterium marinum infection with a multi-drug regimen.
  • Resolution of tenosynovitis and pain following combined medical and surgical intervention.
  • Histopathological confirmation of xanthogranulomatous reaction and microbiological clearance.

Conclusions:

  • A combined medical and surgical approach is effective for treating Mycobacterium marinum-induced tenosynovitis.
  • Early diagnosis and appropriate treatment are crucial for favorable outcomes in fish handler's disease.
  • This case underscores the importance of considering atypical infections in individuals with occupational exposures.
