Erysipelothrix rhusiopathiae endocarditis in man is a very rare disease. The bacteria can be easily misiden- tified as nonpathogenic gram-positive bacilli or streptococci. This organism was isolated from blood samples taken from a 39-year-old male farmer with subacute bacterial endocarditis. The patient had cirrhosis of the liver; diabetes, and tuberculosis. The isolate showed typical cultural and biochemical characteristics such as facultative growth, formation of small greenish colonies on blood agar, positive hydrogen sulfide, negative catalase, and nonmotility. The isolate was susceptible to penicillin G and the cephalosporins.

Objective: To analyze the feasibility and safety of bridge therapy with active fixed electrodes connected to external permanent pacemakers (AFLEP) for patients with infective endocarditis after lead removal and before permanent pacemaker implantation. Methods: A total of 44 pacemaker-dependent patients, who underwent lead removal due to infective endocarditis in our center from January 2015 to January 2020, were included. According to AFLEP or temporary pacemaker option during the transition period, patients were divided into AFLEP group or temporary pacemaker group. Information including age, sex, comorbidities, indications and types of cardial implantable electionic device (CIED) implantation, lead age, duration of temporary pacemaker or AFLEP use, and perioperative complications were collected through Haitai Medical Record System. The incidence of pacemaker perception, abnormal pacing function, lead perforation, lead dislocation, lead vegetation, cardiac tamponade, pulmonary embolism, death and newly infection of implanted pacemaker were compared between the two groups. Pneumothorax, hematoma and the incidence of deep vein thrombosis were also analyzed. Results: Among the 44 patients, 24 were in the AFLEP group and 20 in the temporary pacemaker group. Age was younger in the AFLEP group than in the temporary pacemaker group (57.5(45.5, 66.0) years vs. 67.0(57.3, 71.8) years, P=0.023). Male, prevalence of hypertension, diabetes mellitus, chronic renal dysfunction and old myocardial infarction were similar between the two groups (all P>0.05). Lead duration was 11.0(8.0,13.0) years in the AFLEP group and 8.5(7.0,13.0) years in the temporary pacemaker group(P=0.292). Lead vegetation diameter was (8.2±2.4)mm in the AFLEP group and (9.1±3.0)mm in the temporary pacemaker group. Lead removal was successful in all patients. The follow-up time in the AFLEP group was 23.0(20.5, 25.5) months, and the temporary pacemaker group was 17.0(14.5, 18.5) months. In the temporary pacemaker group, there were 2 cases (10.0%) of lead dislocation, 2 cases (10.0%) of sensory dysfunction, 2 cases (10.0%) of pacing dysfunction, and 2 cases (10.0%) of death. In the AFLEP group, there were 2 cases of abnormal pacing function, which improved after adjusting the output voltage of the pacemaker, there was no lead dislocation, abnormal perception and death. Femoral vein access was used in 8 patients (40.0%) in the temporary pacemaker group, and 4 patients developed lower extremity deep venous thrombosis. There was no deep venous thrombosis in the AFLEP group. The transition treatment time was significantly longer in the AFLEP group than in the temporary pacemaker group (19.5(16.0, 25.8) days vs. 14.0(12.0, 16.8) days, P=0.001). During the follow-up period, there were no reinfections with newly implanted pacemakers in the AFLEP group, and reinfection occurred in 2 patients (10.0%) in the temporary pacemaker group. Conclusions: Bridge therapy with AFLEP for patients with infective endocarditis after lead removal and before permanent pacemaker implantation is feasible and safe. Compared with temporary pacemaker, AFLEP is safer in the implantation process and more stable with lower lead dislocation rate, less sensory and pacing dysfunction.

Infective endocarditis in pregnancy is extremely rare in clinical practice. Guidelines addressing prophylaxis and management of infective endocarditis do not extensively deal with concomitant pregnancy, and case reports on infective endocarditis are scarce. Due to increased blood volume and hemodynamic changes in late pregnancy, endocardial neoplasms are easy to fall off and cause systemic or pulmonary embolism, respiratory, cardiac arrest and sudden death may occur in pregnant women, the fetus can suffer from intrauterine distress and stillbirth at any time, leading to adverse outcomes for pregnant women and fetuses. The disease is dangerous and difficult to treat, which seriously threatens the lives of mothers and babies. Early diagnosis and reasonable treatment can effectively improve the prognosis of patients. The most important method for the treatment of infective endocarditis requires early, adequate, long-term and combined antibiotic therapy. Moreover, surgical controversies regarding indication and timing of treatment exist, especially in pregnancy. In terms of the timing of termination of pregnancy, the timing of cardiac surgery, and the method of surgery, individualized programs must be adopted. A pregnant woman with 30⁺⁵ weeks of gestation is reported. She was admitted to hospital due to intermittent chest tightness, suffocation and fever, with grade Ⅲ cardiac insufficiency. Imaging revealed large mitral valve vegetation, 22.0 mm×4.1 mm and 22.0 mm×5.1 mm, respectively, and severe valve regurgitation. Mitral valve perforation was more likely, blood culture suggested Staphylococcus epidermidis infection, after antibiotic conservative treatment, the effect was poor. After the joint consultation including cardiology, neonatology, interventional vascular surgery, anesthesiology, and obstetrics, the combined operation of obstetrics and cardiac surgery was performed in time. The heart was blocked for 60 minutes, the bleeding was 1 200 mL, the newborn was mildly asphyxiated after birth, and the birth weight was 1 890 g. Nine days after the operation, the patient was discharged from the hospital, and the newborn was discharged with the weight of 2 020 g. Critical cases like this require a thorough weighing of risks and benefits followed by swift action to protect the mother and her unborn child. An optimal outcome in a challenging case like this greatly depends on effective interdisciplinary communication, informed consent of the patient, and concerted action among the specialists involved.

In this study, two school-aged children had an acute onset in spring and had the manifestations of fever, headache, vomiting, disturbance of consciousness, purpura and ecchymosis, and positive meningeal irritation sign. There were increases in peripheral white blood cells and neutrophils, but reductions in the hemoglobin level and platelet count in the two children. They had a significant increase in C-reactive protein. There were hundreds or thousands of white blood cells in the cerebrospinal fluid, mainly neutrophils. Increased protein contents but normal levels of glucose and chloride in the cerebrospinal fluid were found. Head CT scan showed multiple hematomas in the right cerebellum and both hemispheres in one child. Bone marrow cytology indicated infection in the bone marrow, and both blood culture and bone marrow culture showed methicillin-resistant Staphylococcus aureus (MRSA). Both patients had cardiac murmurs and progressive reductions in the hemoglobin level and platelet count during treatment, and echocardiography showed the formation of vegetation in the aortic valve. Therefore, the patients were diagnosed with infectious endocarditis (IE). Vancomycin was used as the anti-infective therapy based on the results of drug sensitivity test. One child was cured after 6 weeks, and the other child was withdrawn from the treatment and then died. Dynamic monitoring of cardiac murmurs should be performed for children with unexplained fever, and echocardiography should be performed in time to exclude IE. IE should also be considered for children with purulent meningitis and skin and mucosal bleeding which cannot be explained by the reduction in platelet count.
