Genome-wide Association Studies-GWAS01:11

Genome-wide Association Studies-GWAS

Genome-wide association studies or GWAS are used to identify whether common SNPs are associated with certain diseases. Suppose specific SNPs are more frequently observed in individuals with a particular disease than those without the disease. In that case, those SNPs are said to be associated with the disease. Chi-square analysis is performed to check the probability of the allele likely to be associated with the disease.
GWAS does not require the identification of the target gene involved in...
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...

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.

Acute Pyelonephritis II: Diagnostic Studies and Management

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...

Acute Pyelonephritis I: Introduction

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 as Proteus,...
Structural Classification of Joints01:20

Structural Classification of Joints

Joints, also known as articulations, are classified based on their structural characteristics, i.e., based on whether the articulating surfaces of the adjacent bones are directly connected by fibrous connective tissue or cartilage, or whether the articulating surfaces contact each other within a fluid-filled joint cavity. These differences serve to divide the joints of the body into three structural classifications.
A fibrous joint is where the adjacent bones are united by fibrous connective...

Summary
This summary is machine-generated.

Acute bacterial arthritis, from gonococcal or nongonococcal infections, is dangerous but treatable. However, risks remain high for vulnerable patients, including those with rheumatoid arthritis or prosthetic joints.

Area of Science:

  • Rheumatology
  • Infectious Diseases

Background:

  • Acute bacterial arthritis stems from gonococcal or nongonococcal joint infections.
  • These infections represent severe and destructive forms of acute arthritis.
  • While curable, significant morbidity and mortality persist in specific patient groups.

Purpose of the Study:

  • To review risk factors, pathogenesis, clinical manifestations, diagnosis, and treatment of bacterial arthritis.
  • To highlight challenges in managing gonococcal and nongonococcal arthritis.

Main Methods:

  • Literature review of existing studies on bacterial arthritis.
  • Synthesis of information on risk factors, disease mechanisms, symptoms, diagnostic approaches, and therapeutic strategies.

Main Results:

  • Identified key risk factors including rheumatoid arthritis, prosthetic joints, advanced age, and comorbidities.
  • Detailed the distinct clinical presentations and diagnostic criteria for gonococcal and nongonococcal arthritis.
  • Outlined current treatment protocols and their effectiveness.

Conclusions:

  • Bacterial arthritis requires prompt diagnosis and treatment.
  • Patient-specific factors significantly influence outcomes and necessitate tailored management approaches.
  • Further research may improve outcomes for high-risk populations.
