Objective:To investigate the changes of local skin temperature in congenital arteriovenous malformations(CAVM) patients before and after treatment,and to assess the relationship between the changes of skin temperature and the outcomes of surgical treatment.Methods: From Sept.2002 to Apr.2006,skin temperatures around the lesions were measured in 22 CAVM patients with WMY-01 digital thermometer before and after surgical treatments,and the opposite side or adjacent skins were taken as controls.Furthermore,changes of flow signals and blood flow velocities in the lesions were measured by color Doppler ultrasonography pre-and post-operatively.Results: Skin temperatures of local lesions decreased from(35.58?(0.68)℃) pre-operatively to(34.76?0.63)℃ post-operatively(P

Botulinum toxin is a potent protein toxin produced by Clostridium botulinum. It acts directly on the brain nerve nucleus and peripheral neuromuscular junction, blocking the release of acetylcholine and thereby affecting nerve impulse transmission, ultimately leading to muscle paralysis. Mild cases may present with ocular muscle involvement, whereas severe cases may involve dysphagia, general paralysis, respiratory depression, and even death. This article reports on a patient who experienced severe poisoning symptoms after using type A botulinum toxin obtained through informal channels. The patient was treated with antitoxin on the 13th day after symptoms onset and achieved a significant improvement in their condition.

Objective:To analyze the case characteristics and outcomes of 12 idiopathic giant cell myocarditis(IGCM)cases after heart transplantation(HT).Methods:From June 2004 to May 2022, clinical data were retrospectively reviewed for 12 cases with pathologically confirm IGCM after HT at Fuwai Hospital.General characteristics, clinical manifestations, pathological examinations and postoperative follow-ups are recorded.Results:From June 2004 to May 2022, a total of 1 143 HT operations are performed at Fuwai Hospital and 12 cases of IGCM(1.05%)are confirmed by postoperative pathology.The age is(47.6±7.3)years.There are 5 boys and 7 girls.Initial presenting manifestations are congestive heart failure(7 cases, 58.3%)and arrhythmia(4 cases, 33.3%). Median time from symptom onset to HT is 6 months.All of them are undiagnosed pre-operation.And dilated cardiomyopathy(5 cases, 41.7%)and arrhythmogenic right ventricular cardiomyopathy(3 cases, 25%)are confirmed.The follow-up period is(4~142)months post-HT.One death occurred during perioperative period and another is due to heart failure at 68 months post-HT.Only 1 case of grade 1R transplant heart rejection occurrs at 9 years post-HT and there is no case of recurrence.According to Kaplan-Meier survival analysis, cumulative survival rates of 1/5/10 years post-HT in IGCM patients are 91.7%, 91.7% and 73.3% respectively.No significant difference exist in survival rate for other etiologies post-HT(Log-rank P=0.265). Conclusions:HT is efficacious for end-stage IGCM.Regular and sufficient postoperative immunosuppression is vital for preventing heart transplant rejection and recurrent IGCM.Most IGCM patients have a decent prognosis post-HT.
