Foul-smelling, frothy white stools
Introduction
Introduction Patients with faecal nematode can excrete squeaky, multi-sparkling white stools and even severe fatty spasms. The strongyloises stercoralis is a facultative parasite with alternating generations. Its self-generated generations are carried out on the ground soil, and the parasitic generations are carried out in the human body. The life history is more complicated and the disease process is long.
Cause
Cause
The filamentous sputum invades the human body through the skin, and the worm body itself and its moving body cause irritation and symptoms.
Examine
an examination
Most of the disease has no clinical symptoms, but it can cause repeated infections due to the body's ability. When the body's resistance is low, if it suffers from various diseases, malnutrition, immunodeficiency or hormone and other immunosuppressive agents, it can often occur repeatedly. Severe self-infection, severe symptoms, and even death.
1. There is no clinical symptom of perianal skin: When the filamentous sputum invades through the skin around the anus, local skin will have edema, tingling and itching, and often accompanied by wire-like or banded urticaria. Since the larva migrates faster in the skin, the urticaria caused by it spreads quickly. It has been reported that a patient's urticaria spreads at a rate of 10 to 12 cm per hour. The appearance and rapid spread of urticaria in the perianal skin is often an important diagnostic basis for the migration of the larvae of the worms in the skin.
2, intestinal symptoms and signs: intestinal symptoms caused by roundworms are mainly long-term diarrhea, frequent diarrhea, visible watery stool or mucus bloody stool, there is urgency and heavy. Followed by abdominal pain, mostly in the right upper abdomen. Occasionally constipation. Severe infections are often accompanied by nausea, vomiting, paralytic ileus, abdominal distension, electrolyte imbalance, dehydration, and even intestinal perforation, systemic failure, and death. Some acute patients can excrete squeaky, smoky white stools and even severe fat cramps. The cause may be related to malabsorption or rupture of the intestinal lymphatic vessels, and fat entering the intestinal lumen.
3, other symptoms and signs: the larvae of the larvae can cause allergic pneumonia and asthma in the lungs, manifested as mild fever, cough, sputum. Chest X-ray examination has localized or diffuse inflammation shadows. The larvae develop into adults as they stay in the lungs, and the larvae sometimes invade the chest and cause pleurisy. In addition, the metabolic products of the worm and the death disintegration products can also cause symptoms of systemic poisoning, such as fever, anemia and neurological symptoms such as irritability and insomnia. Acute infection can cause eosinophilia, often up to 15% to 85%.
Diagnosis
Differential diagnosis
The clinical manifestations of this disease are complex, the course of disease is long, and it is easy to be misdiagnosed, so it should be differentiated from other diseases. When the main complaint is pus and bloody stool, it should be differentiated from bacterial dysentery, amoebic dysentery and ulcerative colitis. When the main complaint is abdominal pain, it should be differentiated from stomach, duodenal ulcer and acute cholecystitis.
