Nevertheless, children with transient synovitis of the hip can usually weight bear. This is an important clinical differentiating sign from septic arthritis. Blood tests may show mild inflammation. An ultrasound scan of the hip joint can show a fluid collection (effusion). Treatment is with nonsteroidal anti-inflammatory drugs and limited weight-bearing. The condition usually clears by itself within seven to ten days, but a small group of patients will continue to have symptoms for several weeks. The recurrence rate is 4–17%, most of which is in the first six months. Symptoms and signs
Transient synovitis causes pain in the hip, thigh, groin or knee on the affected side. However, children with transient synovitis of the hip can usually weight bear with varying degrees of limping. There may be a limp (or abnormal crawling in infants) with or without pain. In small infants, the presenting complaint can be unexplained crying (for example, when changing a diaper). The condition is nearly always limited to one side. The pain and limp can range from mild to severe.Some children may have a slightly raised temperature; high fever and general malaise point to other, more serious conditions. On clinical examination, the child typically holds the hip slightly bent, turned outwards and away from the middle line (flexion, external rotation and abduction). Active and passive movements may be limited because of pain, especially abduction and internal rotation. The hip can be tender to palpation.
Presentation of antibodies when exposed to thermophilic Actinomyces.Examination procedures may include:
• taking a blood test• taking a chest x-ray• administering a breathing capacity test• administering an inhalation challenge• examining lung tissue• performing an immunological investigation• performing a lung function test• reviewing the clinical history

Treatment
Depending on the severity of the symptoms, FLD can last from one to two weeks, or it can last for the rest of ones life. Acute FLD has the ability to be treated because hypersensitivity to the antigens has not yet developed. The main treatment options are: rest and reducing the exposure to the antigens through masks and increased airflow in confined spaces where the antigens are present. Any exposure to the antigens once hypersensitivity has occurred can set off another chronic reaction. For chronic FLD, there are no true treatments because the patient has developed hypersensitivity meaning that their condition will last the rest of their life. Epidemiology
The growth of mold spores occurs when hay is not dried properly. The growth of these mold spores accumulates over time and will infect the host upon release from the source. When in the air, the farmer may inhale the particles and induce an allergic reaction. The hay at risk for increased volumes of spores is found at the bottom of the pile. The presence of Farmers Lung Disease peaks during late winter and early spring and is mostly seen after the harvest season when symptoms have set in. This disease is most prevalent in damp climates.
