Atypical Pneumonia01:14

Atypical Pneumonia

84
Atypical pneumonia, often caused by Mycoplasma pneumoniae, is a form of pulmonary infection that differs from the classical presentation of bacterial pneumonia in both its cause and clinical symptoms. Mycoplasma pneumoniae is a pleomorphic bacterium notable for its lack of a rigid cell wall. This structural characteristic imparts resistance to beta-lactam antibiotics and significantly influences the bacterium’s behavior within the human host.Other pathogens responsible for the disease...

Myocarditis I: Introduction

645
Myocarditis is inflammation of the myocardium, which is the muscular layer of the heart.EtiologyMyocarditis has a diverse etiology, including a wide range of infectious and non-infectious causes:Infectious CausesViral: Common viruses include Coxsackie A and B, adenovirus, parvovirus B19, enteroviruses, and influenza A.Bacterial: Examples include infections caused by Streptococcus, Staphylococcus, and Mycoplasma species.Rickettsial: Infections like Rocky Mountain spotted fever can result in...

Myocarditis II: Clinical Features and Diagnostic Tests

493
Myocarditis is an inflammation of the heart muscle. The symptoms vary widely, encompassing asymptomatic presentations to severe, acute manifestations.Clinical PresentationAsymptomatic cases: In some instances, myocarditis may be asymptomatic, with the infection resolving without intervention. These cases often go undetected unless discovered incidentally through diagnostic imaging or tests conducted for other reasons.General Early Symptoms: Early symptoms of myocarditis are non-specific and can...

Acute Pyelonephritis I: Introduction

1.5K
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...

Acute Pyelonephritis II: Diagnostic Studies and Management

842
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...

Bacterial Phylum Tenericutes01:24

Bacterial Phylum Tenericutes

673
The phylum Tenericutes, which includes the single class Mollicutes, comprises bacteria that lack cell walls. The term "Mollicutes" derives from the Latin word mollis, meaning "soft." These organisms are among the smallest known and are commonly referred to as mycoplasmas due to the prominence of the genus Mycoplasma, which includes well-known human pathogens. Despite their inability to stain gram-positively (a result of their lack of cell walls), mycoplasmas are phylogenetically related to the...

Area of Science:

  • Infectious Diseases
  • Musculoskeletal Infections
  • Tropical Medicine

Background:

  • Tropical pyomyositis involves pus formation in skeletal muscles, presenting as abscesses.
  • While common in tropics, it's increasingly seen in temperate zones, particularly in immunocompromised individuals.
  • India has limited reported cases of this condition.

Purpose of the Study:

  • To investigate causative organisms in tropical pyomyositis.
  • To analyze clinical presentations and diagnostic methods.
  • To evaluate treatment protocols and patient outcomes.

Main Methods:

  • A 3-year study (July 2010-June 2013) at Nilratan Sircar Medical College and Hospital, Kolkata.
  • Inclusion of 12 patients diagnosed with tropical pyomyositis via muscle pus aspiration and culture.
  • Systematic recording of all investigation and treatment data.

Main Results:

  • All 12 patients presented with high fever and myalgia.
  • Quadriceps femoris (50%) and iliopsoas (25%) were the most affected muscles.
  • Staphylococcus aureus was identified in 75% of cultures; Klebsiella pneumoniae in 8.33%.

Conclusions:

  • Tropical pyomyositis can occur in immunocompetent individuals.
  • Staphylococcus aureus is the predominant causative agent.
  • Early antibiotics and surgical debridement are vital for good prognosis, which is excellent if treated promptly.
