Summary
Tropical fevers like dengue and scrub typhus are common in Indian ICUs, causing organ failure. Early diagnosis and treatment are crucial for better outcomes in critically ill patients.
Area of Science:
- Critical Care Medicine
- Infectious Diseases
- Public Health
Background:
- Tropical fevers often present with undifferentiated symptoms and organ failures.
- A nationwide study was conducted to understand tropical fevers in Indian Intensive Care Units (ICUs).
Purpose of the Study:
- To identify the prevalence, clinical profile, resource utilization, and outcomes of tropical fevers in Indian ICUs.
- To inform diagnostic and therapeutic strategies for tropical fevers.
Main Methods:
- A multicenter prospective observational study involving 34 ICUs across India.
- Enrolled critically ill adults and children with nonlocalizing fever and signs of organ dysfunction.
Main Results:
- Dengue, scrub typhus, encephalitis, and malaria were the most common etiologies.
- High rates of mechanical ventilation, vasoactive therapy, and renal replacement therapy were observed.
- Mortality was 18.4%, with higher rates in patients with undiagnosed etiology.
Conclusions:
- Dengue, scrub typhus, encephalitis, and malaria are leading causes of tropical fevers in Indian ICUs.
- A syndromic approach, point-of-care tests, and empiric antimicrobial therapy are recommended.

The International System of Units or SI system, by international agreement, has fixed measurement units for seven fundamental properties: length, mass, time, temperature, electric current, amount of substance, and luminosity. These are called the SI base units.

Every measurement provides three kinds of information: the size or magnitude of the measurement (a number), a standard of comparison for the measurement (a unit), and an indication of the uncertainty of the measurement. While the number and unit are explicitly represented when a quantity is written, the uncertainty is an aspect of the errors in the measurement results.

The signs and symptoms of fever include hot and dry skin, flushed face, thirst, muscle aches, anorexia, headache, tachycardia, tachypnea, and fatigue. Elevated body temperature is reduced using two methods: pharmacological and nonpharmacological. Proper identification and treatment of the root cause of a fever is of utmost importance.

Varicose veins, or varicosities, develop when the valves in the veins, which control blood flow, weaken or damage. It causes blood to pool and the veins to enlarge. Understanding the clinical manifestations, diagnostic approaches, and management options for varicose veins is crucial for effective treatment and relief.Clinical manifestationsClinical manifestations of varicose veins include a heavy, achy feeling or pain after prolonged standing or sitting. This discomfort can often be relieved by...
