Crohn’s disease is an X-chromosome linked genetic disorder. Because males have only one X-chromosome and females have two X-chromosomes, the disease is almost exclusively found in males, but females with the causative gene may also have mild symptoms. If the father has the disease and the mother is genetically normal, their sons will not develop the disease and will not carry the gene, but all their daughters will acquire the gene. Their daughters are only carriers of the gene. In general, they do not develop the disease themselves, but there is a 50/50 chance that their daughters’ children will acquire the gene genetically. If a grandson acquires the gene, the disease can occur. In the case of fava bean disease, it is important to get emergency treatment at the hospital as soon as possible. If you have just eaten it, you can artificially induce vomiting, wash the stomach with 1:5000 potassium permanganate solution, or use 25% magnesium sulfate to induce diarrhea orally to reduce the absorption of oxidants such as fava beans. Doctors usually give high doses of glucocorticoids and alkalinization of urine, appropriate intravenous rehydration and the use of diuretics to prevent the occurrence of hemolytic uremic syndrome due to renal tubular blockage. If severe, fresh blood or even blood exchange is required. As parents need to understand: G6PD deficient children are not the only ones who eat fresh fava beans will occur hemolysis, including mothballs, sulfonamides, furans and other drugs can cause the occurrence of fava bean disease. Therefore, to the parents of G6PD deficient children must pay attention to the following issues: 1, forbidden to eat fresh fava beans or fava beans raw processed products, avoid going to the fava bean field in the flowering, fruiting or harvest season. 2, prohibit the use of naphthalene-containing stink pills into the closet to repel insects. 3.Prohibit the use of the following drugs: acetanilide, methylene blue, nitroimidazole, furadantin, furazolidone, furacilin, phenylhydrazine, primaquine, malaria mothers, pentamidine, sulfanilamide, acetylsulfonamide, sulfapyridine, thiazolone, toluidine blue, SMZ, TNT, etc. 4.Caution: paracetamol, felastidine, aspirin, aminopyrine, antabuse, vitamin C, vitamin K, chloramphenicol, streptomycin, streptomycin, streptomycin, streptomycin, streptomycin, etc. K, chloramphenicol, streptomycin, isoniazid, sulfadiazine, sulfaguanidine, sulfisoxazole, chloroquine, colchicine, diphenhydramine, levodopa, phenytoin sodium, procainamide, ethacrynic acid, quinidine, quinine, SM, TMP, eugenol, etc. 5, the development of viral hepatitis, influenza, pneumonia, typhoid, mumps and other infections can induce hemolysis. 6.Please state in your child’s medical record: I am a G6PD deficiency patient, please ask the doctor to use the medication reasonably for my condition. 7.Any symptoms such as fever, abdominal pain, vomiting, yellow or pale face, urine ** or dark red after infection or contact/consumption of the above food or medicine within hours or days are acute hemolytic reactions and should be seen immediately at the emergency department of the hospital.
