For years, migraines have been the subject of extensive research, as their symptoms significantly burden individuals' quality of life. Existing treatments primarily rely on pharmaceutical interventions targeting various symptoms associated with migraines. However, the varying efficacy and side effects of these medications have led to the consideration of alternative treatment modalities to improve patient outcomes and minimize adverse effects.

Bacterial urinary tract infections (UTIs) are common, ranging from benign cystitis to complicated pyelonephritis, which can lead to severe complications such as pyonephrosis and sepsis. Pyonephrosis, characterized by the presence of pus in the renal cavities, often requires urgent urological intervention. We report a unique case of pyonephrosis with a psoas abscess caused by and in a 64-year-old diabetic female patient.

Introduction: The use of urine cytobacteriological examination is a common and essential practice in medicine which helps guide therapeutic management in case of urinary tract infection. The cytological examination of urine samples can be done using the manual (microscopic) or automated technique. The automated approach, which involves the use of artificial intelligence, is faster, more reliable, and more efficient for laboratories.

Background: Urinary tract infection, defined as the presence of bacteria or yeast in the urinary tract, is the most common community-acquired infection after respiratory infections. The cytobacteriological examination of urine (CBEU) remains the primary diagnostic test for urinary tract infections and is the most frequently conducted test in microbiology laboratories. Direct examination is a crucial step of CBEU, enabling the assessment of cytology, including leukocytes and red blood cells, as well as the identification of crystals, epithelial cells, and microorganisms when present in significant quantities.

Article Synopsis
  • Williams and Trotman aimed to automate bacteriology processes since 1960, but faced challenges like high costs and traditional methods that delayed progress.
  • Automation started with blood culture incubators and eventually improved efficiency in various bacteriology areas, such as cytology and antibiotic testing, leading to faster lab results and enhanced quality.
  • The integration of artificial intelligence in bacteriological analyses signifies a further transformation, resulting in fully automated labs with less human involvement, ultimately impacting healthcare quality.

Peritoneal dialysis is a blood purification technique used in cases of end-stage chronic kidney failure, based on the filtering capabilities of the peritoneum. Infections, often caused by poor asepsis during catheter manipulation, are generally attributed to and , usually considered non-pathogenic, is rarely involved in these infections. We present a case of peritonitis due to in a patient undergoing peritoneal dialysis.

Peritonitis is characterized by acute inflammation of the peritoneum, often resulting from digestive organ perforation or intra-abdominal septic focus. It may be of either infectious or non-infectious origin. The bacteria involved are those of the digestive flora ( and anaerobes), while Gram-positive cocci and yeasts can be isolated in nosocomial infections.

  • Pasteurella is a common microorganism usually found in the upper respiratory and digestive tracts of mammals and birds, and it rarely affects humans.
  • Human infections, called pasteurellosis, usually occur from bites or scratches from domestic animals, like dogs and cats, but can also come from other animals, including wildlife.
  • The case presented involves a young woman who developed a hand infection after a rare human bite during a fight, but her condition improved with surgery and medication.
