Unexplained fever or high fever in a child without symptoms
Today I want to talk with you on the topic “fever of unknown origin.” This implies a high temperature, more than 38.3 degrees, which lasts more than 3 weeks. However, even a thorough examination does not give an answer to why it arose. Parents are worried, the child is suffering, so let’s figure it out now.
In the past, people believed that fever was something demonic and supernatural. They believed that it was necessary to get rid of it immediately. In the 18-19 centuries, many people died from yellow, purple, typhoid fever and dengue. The doctors of that time treated her as best they could, and often with wild methods. For example, they caused vomiting, sweating, or bleeding.
It’s good that medicine has gone far ahead. Modern people know that high fever is the body’s response to the disease, not the disease itself. When body temperature rises, it helps a person overcome infections. For example, 40-41 degrees slows the reproduction of viruses two hundred times. Also, it triggers the protective function of the immune system. More cells are released from the bone marrow into the bloodstream. The process occurs under the influence of the pattern of macrophages to cope with the absorption of bacteria. B cells produce more antibodies.
When diagnosing a fever, they study her history and document her model, a total of 6.
Constant – high temperature has been observed for a long time. Within a few days, between measurements in the morning and evening, the difference does not exceed 1 degree.
Remitting (laxative) – the temperature is high, and in the morning at least 37 degrees. Daily fluctuations exceed 1-2 degrees.
Intermittent (intermittent) – the temperature remains normal, but short-term increases to high levels are observed. This alternates in 1-2 days.
The reverse type is that in the morning the temperature is higher than in the evening.
Hectic (depleting) – there is a high temperature, daily fluctuations exceed 2-4 degrees.
Wrong (atypical) – a random alternation of high and low temperature indicators. As a rule, observed with sepsis.
When a specialist collects an anamnesis, he attaches particular importance to a number of issues. Parents should be ready to answer them.
Whether the child traveled abroad and when there was a trip. If so, then the incubation period is calculated: more or less than 21 days. Next, a diagnostic search is performed.
Whether the child was hospitalized or hospitalized. If the answer is yes, then the specialist follows in 3 directions of search. It turns out whether there is a urinary catheter at the moment or whether it has been placed recently. What were the recent procedures and what was the nature of antibiotic therapy.
If there were no hospitalizations, then a specialist can exclude drug fever. Then the specialist finds out the main etiology, which can be infectious, inflammatory, malignant, etc.
At the first examination of a small patient, diagnostic tips may be missed. But in the following tricks, they can become apparent. That is why repeat visits are reasonable.
When an adult or a child has a fever, a series of examinations are prescribed. Starting methods become the foundation for future differential diagnostics and the appointment of in-depth diagnostic methods. The latter are more invasive, traumatic or expensive. The set of starting analyzes includes:
A detailed general analysis of the shelter (KLA);
biochemical blood test (LHC);
general urine analysis;
urine / blood culture;
Mantoux test, or diaskin test;
Ultrasound of the abdominal cavity, thyroid gland and pelvis.
