Une étude parasitologique a été menée chez 198 chiens vivant en liberté quasi complète dans des villages du Nord-Est du Gabon. Des échantillons de fèces ont été prélevés et analysés. Une prévalence du parasitisme digestif de 91 % (181/198) a été mise en évidence par coproscopie microscopique (méthode d'enrichissement par flottation). La prévalence, par parasite, est de 59 % pour les ascarides, de 49 % pour les trichures, de 35 % pour les ankylostomes, de 25 % pour les spirocerques, de 11 % pour les capillaries et de 10 % pour les coccidies. Des embryophores de cestodes ont été retrouvés dans 17 échantillons (9 %).
Background: This study aimed to propose a classification of acetabular defects in advanced-stage hip tuberculosis based on preoperative radiographs and intraoperative evaluation, thereby providing options for reconstructing each type of defect in hip arthroplasty. Materials and Methods: We conducted a prospective study with 45 patients with active hip tuberculosis at stage IV who were treated with a total hip replacement strategy. We collected the patients' acetabular defect data from preoperative radiographs and intraoperative observations. The defects were classified into types based on defect severity and reconstructive complexity. The hip replacement outcomes were evaluated at least 12 months after the operation. Results: The classification system includes three types: type I: localized or extensive defects inside the acetabulum, not affecting the acetabular rim, medial wall, or columns. Type II: extensive defects inside the acetabulum, affecting the acetabular rim or (and) medial wall. Type III: extensive defects inside the acetabulum, causing the medial wall and the acetabular column to lose function. Each type has a corresponding reconstruction. The outcome includes that 41/45 patients had excellent results; 3/45 patients had good results. The patients had good results due to nerve and muscle damage caused by tuberculosis not related to the acetabular defects. Conclusion: This is a simple, practical classification system of acetabular defects in hip tuberculosis. The outcome of hip reconstruction using this classification was excellent without any cases of dislocation or protrusion.
Background : Total hip replacement during active hip tuberculosis has been a controversial issue for a long time. Some authors advocate hip replacement during the healed stage, while others believe it should be done in active hip tuberculosis. The purpose of this study was to describe the surgical outcomes, a suitable time and necessary conditions for the total hip replacement in active hip tuberculosis. Methods: We conducted a quasi-experimental study. The study enrolled 40 patients with 42 active tuberculosis hips at stage IV treated by total hip replacement strategy between October 2016 and December 2019 at the National Lung Hospital, Vietnam. The patients had been done total hip replacement by either one- or two-stage depending on hip abscesses to assess surgical outcomes and some factors associated with the logistic regression analysis model. The patients were then evaluated based on Harris hip score and sinus tract formation. Results: The average follow-up was 30 months (range, 14-50 months). Surgical outcomes showed that 37 cases (88.1%) had an excellent hip function and no abscess or sinus tract formation. Four cases (9.5%) had sinus tract formations, but the hip function was still in the excellent class by Harris hip-score (HHS). One case (2.4%) had a good hip function with a Harris hip score of 86 points, without sinus tract formation. The binary logistic regression models revealed that sinus tract formation was associated with preoperative tuberculosis infection syndrome but not associated with pulmonary tuberculosis, acetabular osteomyelitis, trans-trochanteric osteomyelitis, a history of diabetes, rheumatoid arthritis, or corticosteroid dependence. The average time from patients getting antituberculosis treatment to hip replacement was 4.6 weeks. Conclusion: Total hip replacement for active hip tuberculosis was a practical and promised treatment method (excellent result: 88.1% and good: 11.9%). The surgery should be considered to improve patients' conditions pre-operation in taking anti-tubercular drugs, eliminating all abscesses, diminishing tuberculosis infection syndrome, inflammatory response, and choosing a suitable time of getting tuberculosis treatment.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
