Abstract: The patient, Mr. Li, had alternating diarrhea and constipation for 1 month, accompanied by abdominal pain and loss of appetite, which was considered to be possible enteritis. The patient expressed anal itching and then associated it with possible parasitic infection. The diagnosis of tapeworm disease was confirmed by anal swab examination and the patient was given deworming treatment and targeted treatment for loss of appetite. [Basic information] Male, 40 years old [Disease type] Tapeworm disease [Hospital] Beijing Huairou District Hospital of Traditional Chinese Medicine [Consultation date] March 2, 2022 [Treatment plan] Medication (Levofloxacin hydrochloride tablets + Praziquantel tablets + Lactase tablets + Ginseng Jianzhuwan) [Treatment cycle] Outpatient treatment for 1 month, followed by outpatient review after 1 month [Treatment effect] Symptoms such as diarrhea, constipation and abdominal pain disappeared. Patient Mr. Li, 40 years old, came to the hospital with abdominal pain for the past 1 month, and his stools were sometimes thin and sometimes dry, and the symptoms of abdominal pain and diarrhea worsened in the past 3 days. In the last 3 days, diarrhea was aggravated with watery stools, 5-6 times a day, and his appetite was reduced compared with the previous one, and he had vague pain in the upper abdomen after eating. Subsequently, the patient’s stool routine and abdominal CT did not show any abnormality, and blood analysis indicated elevated leukocytes and neutrophils, so enteritis was considered. Initially, inflammatory infection was considered, and the patient was given levofloxacin hydrochloride tablets for anti-infection treatment, but the symptoms did not improve after 3 days. The patient complained that he sometimes had anal itching, and his symptoms were relieved by self-application of miconazole nitrate cream. It was considered that if the patient had eggs or parasitic secretions in the anus, they could also cause anal pruritus. After taking an anal swab, microscopic examination revealed tapeworm eggs, and the final diagnosis of tapeworm disease was confirmed. Praziquantel tablets were given in sufficient doses orally and levofloxacin hydrochloride tablets for anti-infection treatment. The patient was instructed to come back to the clinic in 1 week if her symptoms improved, and to return to the clinic at any time if her symptoms worsened or other special discomfort appeared. The patient returned to the clinic 1 week later and complained of significant improvement in abdominal pain and diarrhea, with loose stools, 1-3 times a day, and no watery stools. Anal itching basically disappeared after 2 days of taking the medicine. However, there was still a loss of appetite. considering the possible presence of dyspepsia, lactase tablets and ginseng spleen pills were given orally to promote appetite. after 1 month follow-up, the patient had no discomfort and his appetite had returned to normal. IV. Precautions We are glad that the patient’s disease was cured after active treatment. Since tapeworms are usually found in pork, tapeworm disease may result if raw meat or meat that is not thoroughly cooked is consumed. The Chinese family diet is usually a shared dish, so it is easy for multiple family members to share tapeworm disease, so the patient’s family is advised to come to the hospital for tapeworm-related tests if possible. Patients should be instructed to heat meat sufficiently in the future and wait until it is cooked before eating it, and that knives and plates that have touched raw meat should not touch other foods, and that hands that have touched raw meat must be thoroughly washed before other operations. V. Personal insight Tapeworm disease is generally mild and most patients can be cured after deworming treatment, but some people may develop cysticercosis, which means that the larvae of tapeworm parasitize the body’s muscles, subcutaneous, lungs and even the brain, and the disease is more serious at this time. The larvae of tapeworm parasitize the subcutaneous area and are visible to the naked eye as scattered subcutaneous cystic bumps; parasitizing the muscles may cause muscle weakness and soreness; parasitizing the brain may cause dizziness and headache, nausea, vomiting, and even hemiplegia and abnormal mental status.
