Biofilms busters to improve the detection of Borrelia using PCR.

Lyme disease is an affection caused by a spirochete infection called Borrelia Burgdorferi which may harbor a varied and misleading clinical symptomatology. The serology tests commonly used for diagnosis show a wide sensitivity varying from 34% to 70,5%, leaving many infected patients with false negative tests. Alternative techniques such as polymerase chain reaction (PCR) could be helpful but not conclusive enough. Using biofilm busters, such as stevia and serratiopeptidase, could lead to bacterial blood release, thus increasing the spirochete load, making PCR test more sensitive, thus improving the patient's diagnosis and management.

[Treatment of primary thyroid lymphomas]. / Traitement des lymphomes thyroïdiens primitifs de stade localisé

Primary lymphomas of the thyroid (LPT) are a rare entity. LPT represent between 5 and 15% of all thyroid neoplasms. Cytology has limited value; biopsy should be recommended. The differential diagnosis of thyroid carcinoma is differentiated forms indolent or aggressive forms for anaplastic and high grade that may occur by a mass rapidly progressive and compressive. LPT represent a histologically and clinically heterogeneous disease. The most common forms are high-grade LPT (DBLCL) of diffuse large cell type or mucosa-associated lymphoid tissue (MALT). DBLCL receive chemotherapy. The benefit of irradiation is highly debated in view of the data from randomized lymphoma studies (nodal with a minority of extranodal forms) versus those of retrospective studies specifically addressing the case of LPT. Localized MALT lymphomas can be treated with radiation alone. The treatment of other LPT is presented.

Computed tomography- and fluoroscopy-guided percutaneous screw fixation of low-grade isthmic spondylolisthesis in adults: a new technique.

OBJECTIVES: To evaluate the feasibility of computed tomography (CT)- and fluoroscopy-guided percutaneous screw fixation for the treatment of low-grade isthmic spondylolisthesis in adults. METHODS: Ten consecutive adult patients (four men and six women; mean age: 57.1 [range, 44-78 years]) were prospectively treated by percutaneous screw fixation for low-grade (six grade 1 and four grade 2) isthmic spondylolisthesis of L5. For each patient, two 4.0-mm Asnis III cannulated screws were placed to fix the pars interarticularis defects. All procedures were performed under local anaesthesia by using CT and fluoroscopy guidance. Post-operative outcome was assessed using the visual analogue scale and Oswestry Disability Index (ODI) scores. RESULTS: The procedure time ranged from 45 to 60 min. The mean screw length was 27 mm (range, 24-32 mm). The VAS and ODI measurements ± SD decreased from 7.8 ± 0.9 preoperatively to 1.5 ± 1.1 at the last 2-year follow-up, and from 62.3 ± 17.2 to 15.1 ± 6.0, respectively (P < 0.001 in both cases). Neither slip progression nor screw failure was noted. CONCLUSIONS: This feasibility study showed that CT- and fluoroscopy-guided percutaneous screw fixation could be a rapid, safe and effective method of treating low-grade isthmic spondylolisthesis. KEY POINTS: CT- and fluoroscopy-guided percutaneous screw fixation of isthmic spondylolisthesis is feasible. It could become an effective method to treat low-grade isthmic spondylolisthesis. Percutaneous trans-isthmic screw fixation can be performed under local anaesthesia. This new technique can be performed as an outpatient procedure.
