Summary
Cephalexin, a common antibiotic, can rarely cause hypersensitivity vasculitis, leading to skin lesions and acute kidney failure. This rare reaction required hospitalization and dialysis.
Area of Science:
- Nephrology
- Dermatology
- Immunology
Background:
- Antibiotic allergies are frequently reported, but cephalosporin hypersensitivity is uncommon.
- Severe dermatologic and systemic reactions involving end-organ damage from cephalosporins are rare.
Observation:
- A patient presented with non-blanching purpuric lesions, a characteristic sign of vasculitis.
- The patient also exhibited signs of acute kidney failure.
Findings:
- The presented case links cephalexin (a cephalosporin antibiotic) exposure to the development of hypersensitivity vasculitis.
- The vasculitis manifested as purpuric lesions and was associated with acute kidney injury.
Implications:
- This case highlights a rare but severe adverse reaction to cephalexin, emphasizing the need for vigilance.
- Early recognition and management, including hospitalization and hemodialysis, are crucial for patients experiencing such reactions.

40
Pyelonephritis is a bacterial infection that primarily affects the renal parenchyma and collecting system, including the renal pelvis, tubules, and interstitial tissue of one or both kidneys. It can be classified as either acute—a sudden, severe infection—or chronic, which refers to long-term or recurrent kidney infections.The primary cause of acute pyelonephritis (APN) is bacterial infection, with Escherichia coli accounting for approximately 70-80% of cases. Other bacteria, such...

01:28Acute Pyelonephritis II: Diagnostic Studies and Management
34
Introduction:For diagnosing acute pyelonephritis, a comprehensive patient history is collected to identify symptoms such as dysuria, frequent or urgent urination, flank pain, or costovertebral angle (CVA) tenderness that may suggest a kidney infection.Physical ExaminationDuring the physical examination, CVA tenderness is assessed. This involves gentle percussion over the costovertebral angle, where tenderness often indicates a kidney infection.Diagnostic TestsUrinalysis: Used to identify white...

Leukocyte disorders can lead to either leukopenia, characterized by an abnormally low leukocyte count, or leukocytosis, marked by a very high leukocyte number.
Leukopenia may result from bone marrow disorders, autoimmune diseases, and infectious diseases. For example, conditions such as multiple myeloma and aplastic anemia can impair the bone marrow's ability to produce adequate leukocytes. Similarly, autoimmune diseases like lupus and viral infections such as HIV can prompt the immune...

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...
