  • 简介:AbstractBackground:Mallet fracture is avulsion of the terminal extensor tendon from the base of the distal phalangeal bone with a bony fragment. This study was performed to evaluate the anatomical characteristics of mallet fractures, investigate a new mallet fracture classification system using anatomical and imaging methods, and discuss the treatment schemes for different types of mallet fracture.Methods:Sixty-four fresh cadaveric fingers were divided into four groups, and models of different types of mallet fracture with distal interphalangeal joint instability were established by dissecting 25%, 50%, 75%, and 100% of the bilateral collateral ligaments. The effect of mallet fractures on the stability of the distal interphalangeal joint was then observed. The lateral radiographs of mallet fractures in 168 patients were analyzed and classified according to the involvement of the joint surface in the fracture, the thickness of fracture, the untreated time after injury, and the complication of distal interphalangeal joint palmar subluxation. Forty-seven patients were surgically treated by reconstruction of extensor tendon insertion, the Ishiguro method, or single Kirschner wire fixation.Results:The established mallet fracture model showed that the distal interphalangeal joint was stable when the bilateral collateral ligaments were cut off by 25% (t= -0.415, P = 0.684) and significantly unstable when this range was ≥50% (50% transection: t= -6.363, P < 0.001; 75% transection: t= -17.036, P < 0.001; 100% transection: t = -30.977, P < 0.001, respectively). The mallet fractures were divided into Types I, II, and III (fracture involving <20%, 20%-50%, and >50% of the joint surface, respectively). Type II was further divided into Types IIa and IIb according to whether the course of injury was < or ≥2 weeks, respectively. The mean post-operative flexion of the distal interphalangeal joint was 63.4° ± 7.9°, and the mean extension lag was 6.7°± 4.6°.Conclusions:The lateral collateral ligament is the main factor that maintains the stability of the distal interphalangeal joint. Classification that combines the involvement of the joint surface in the fracture, the thickness of the fracture, and the untreated time after injury is reasonable and will help to choose an appropriate operational method.

  • 简介:AbstractIntroduction:Basal cell carcinoma (BCC) is the most common skin cancer which mainly affects the population over 50 years of age. In addition to surgical treatment, nonsurgical treatment is also an attractive option for some patients.We herein report a case of an 82-year-old man with BCC successfully treated with acitretin.Case presentation:An 82-year-old man presented with BCC on his left nose wing more than 2 years ago. Due to his unwillingness to accept treatment that may lead to pain, discomfort, or trauma, the patient was prescribed oral acitretin 25 mg twice daily [0.8 mg/(kg·d)] and was instructed to apply 2% fusidic acid cream topically once daily for trauma protection. The lesion progressively shrank in size after 4 weeks of treatment, and was almost completely resolved after 28 weeks of follow-up. The patient reported mild adverse effects, such as mild skin fragility and cheilitis, and apparent scaling skin, which caused minor discomfort but did not affect the continuation of treatment.Discussion:The pathogenesis of BCC is still unclear, but it has been demonstrated to be linked to overactive hedgehog signaling and its crosstalk with other pathways such as phosphoinositide 3-kinase and mammalian target of rapamycin. Acitretin could obviously inhibit cell growth and proliferation and down-regulate AMP-dependent protein kinases that plays critical role in the blocking of malignant progression of several tumors including BCC.Conclusion:We provide an effective alternative for the patients with BCC who are unwilling to receive surgical therapy.

  • 简介:AbstractSevere fever with thrombocytopenia syndrome (SFTS), caused by a novel identified bunyavirus SFTS virus (SFTSV), was an emerging viral infectious disease that was firstly reported in China. There are no licensed vaccines and therapeutics against SFTSV currently. B-Propiolactone (BPL) inactivated whole virions of SFTSV strain AH12 were prepared as experimental vaccine in different antigen dose with or without Al(OH)3 adjuvant. The experimental SFTS vaccine was a satisfying immunogen, which could efficiently trigger the development of high levels of SFTSV NP-specific IgG antibodies and neutralizing antibodies against SFTSV Strain HB29 in BALB/c and C57/BL6 mice, and could induce SFTS virus-specific cellular immune responses to a certain extent. A single dose of vaccine was immunogenically insufficient in BALB/c mice; the second and third dose resulted in significant boost in antibody response. The use of Al(OH)3 adjuvant resulted in higher antibody titers. The mediate-dose of vaccine could induce as high and equivalent level of antibody titer as that of high-dose. The experimental SFTS vaccine in mediate-and high antigen dose with adjuvant resulted in solid protection of C57/BL6 mice against wild-type SFTSV challenge with markedly accelerated virus clearance from blood and spleen compared with controls. The experimental SFTS vaccine prepared in this study could efficiently elicit virus specific humoral and cellular immune responses in both BALB/c and C57/BL6 mice, and could protect C57/BL6 mice against SFTS virus challenge. These results supplied evidence that inactivated vaccine was a promising vaccine candidate for the prevention of SFTSV infection.

  • 简介:摘要The COVID-19 pandemic affects a large number of patients with a rapid progression of respiratory failure often requiring hospitalization or intensive care unit treatment in some patients. Survivors of severe COVID-19 suffer from persistent weakness and cardiorespiratory failure. Feasibility and potential benefit of cardiopulmonary rehabilitation (CR) after COVID-19 remains unclear. Therefore, we retrospectively analyzed a cohort of COVID-19 patients in a single center inpatient rehabilitation clinic and describe performance and outcome during CR.Patients were referred from acute care hospitals for rehabilitation after severe COVID-19. The cohort (n=28) was divided in ventilated or not ventilated patients for further analysis. 50% were female, mean age was 66 years and patients stayed in the acute hospital for 19.3±10.7 days before referral for CR. 17 patients (61%) needed previous ICU treatment in the acute care hospital. Risk factors, assessments and questionnaires on admission were comparable in both groups. Significant enhancements were observed in 6-minute walking test and Feeling Thermometer which were independent of previous ventilation status.In conclusion, comprehensive CR following COVID-19 is safe, feasible and effective. Improvements in physical performance and subjective health status were independent of previous ventilation.
