Atlanto-axial infection after acupuncture

Surgery combined with antibiotics for thoracic vertebral Escherichia coli infection after acupuncture: A case report

BACKGROUND

Acupuncture is relatively popular worldwide, but an unregulated operation can easily lead to infections. The purpose of this report was to analyze a clinical case of surgery combined with the use of antibiotics for the treatment of thoracic vertebral infection by Escherichia coli (E. coli) after acupuncture.

CASE SUMMARY

A 63-year-old male was diagnosed with E. coli infection in the thoracic vertebra after acupuncture. His fever and pain did not improve after treatment with broad-spectrum antibiotics for 10 d. Thus, debridement of the infected area and biopsy were decided. The final pathology confirmed the diagnosis of vertebral infection by E. coli. The patient underwent anterior and posterior thoracic vertebral debridement and internal fixation surgery combined with the use of sensitive antibiotics. He had no fever or backache 3 mo postoperatively.

CONCLUSION

In this report, we first considered antibiotic treatment for the patient with septic spinal infection, but the effect was not obvious. Interventional surgery was combined with the use of sensitive antibiotics to relieve backache, and good clinical results were achieved. Furthermore, acupuncture practitioners should pay attention to hygienic measures.

Atlanto‐odontoid pyogenic arthritis revealing a Jugular Vein Thrombosis

Pyogenic arthritis of the atlantoaxial joint is scarce. It can lead to several complications, such as spinal cord compression and cerebral vein thrombosis. A 51‐year‐old man presented with a twenty‐day history of inflammatory neck pain. Physical examination revealed paravertebral muscle contracture, restricted neck movement, and fever. Spine magnetic resonance imaging (MRI) showed synovitis of atlanto‐odontoid joint, anterior epidural collection, and cerebral vein thrombosis. Transthoracic echocardiography was unremarkable. The patient was successfully treated with anti‐staphylococcal antibiotic treatment for 12 weeks associated with immobilization of the cervical spine. MRI performed one month after the initiation of the treatment showed disappearance of the epidural collection. The diagnosis of septic arthritis of the atlantoaxial joint should be considered in a patient with inflammatory neck pain. MRI findings are relevant in making the diagnosis of a septic atlanto‐odontoid joint. Conservative treatment, including antibiotic and neck immobilization, can be sufficient for the treatment of pyogenic arthritis of the atlantoaxial joint. Cerebral vein thrombosis is a rare complication due to septic arthritis of the atlantoaxial joint.

Successful treatment with mepolizumab for allergic bronchopulmonary mycosis complicated with bilateral septic arthritis of the knee joints caused by Methicillin-resistant Staphylococcus aureus

We report the case of a 50-year-old man with allergic bronchopulmonary mycosis (ABPM) complicated with bilateral septic arthritis of the knees caused by Methicillin-resistant Staphylococcus aureus (MRSA). He had a background of bronchial asthma and end-stage renal failure on maintenance dialysis. He was treated with 30 mg/day of prednisolone for 14 days for ABPM. He developed bilateral septic arthritis of the knees, caused by MRSA during prednisolone treatment. He underwent bilateral arthroscopic washout with a 2-week course of intra-articular arbekacin, concomitantly treated with a 6-week course of intravenous teicoplanin and oral rifampicin, subsequently followed by oral linezolid treatment. However, he suffered exacerbation of ABPM during treatment of septic arthritis. Because of these serious infectious complications, he was treated with mepolizumab instead of corticosteroids for the ABPM, which resolved all symptoms and clinical features. This case highlights mepolizumab treatment as an alternative to corticosteroid therapy for treatment of ABPM in patients with comorbidities such as infection.

Metastatic infection during Staphylococcus aureus bacteremia

Staphylococcus aureus causes various infections, including skin and soft tissue infections and pneumonia via both, community-associated and nosocomial infection. These infectious diseases can lead to bacteremia, and may subsequently result in metastatic infections in several cases. Metastatic infections are critical complications in patients with S. aureus bacteremia, since the optimal duration of the antimicrobial treatment differs in patients with and without metastatic infection. Notably, two weeks of antimicrobial treatment is recommended in case of uncomplicated S. aureus bacteremia, whereas in patients with S. aureus bacteremia-associated endocarditis or vertebral osteomyelitis, six weeks of antimicrobial administration is vital. In addition, misdiagnosis or insufficient treatment in metastatic infection is associated with poor prognosis, functional disability, and relapse. Although echocardiography is recommended to examine endocarditis in the patients with S. aureus bacteremia, it remains unclear which patients should undergo additional examinations, such as CT and MRI, to detect the presence of other metastatic infections. Clinical studies have revealed that permanent foreign body and persistent bacteremia are predictive factors for metastatic infections, and experimental studies have demonstrated that the virulence factors of S. aureus, such as fnbA and clfA, are associated with endocarditis; however, these factors are not proven to increase the risk of metastatic infections. In this review, we assessed the incidence, predictive factors, diagnosis, and treatment for metastatic infections during S. aureus bacteremia.
