Résumé
Prosthetic infection is one of the severe postoperative complications of arthroplasty. Mixed bacterial-fungal prosthetic infection is rare but can be disastrous. This case was a 76-year-old female suffered from prosthetic infection following total hip replacement due to femoral neck fracture and underwent multiple debridements. The culture of periprosthetic tissue was bacteriologically sterile following the first debridement, while the Staphylococcus hominis was identified in the second debridement in the previous hospitalization where fungal infection had not been considered. Thus the pathogen spectrum of anti-infection therapy failed to contain fungus. Ultimately, the culture result of our sampled periprosthetic tissue during the third debridement was Candida albicans without bacterium in our hospital. The fungal prosthetic infection was successfully treated by a two-stage revision with antifungal drugs. Accurate diagnosis and standardized treatment is the key to the therapy of infection after hip arthroplasty, especially for mixed bacterial-fungal prosthetic infection.

Arthroscopic superior capsular reconstruction is an innovative technique for the irreparable rotator cuff tears, but spontaneous pneumothorax after surgery is very rare. The present case was a 66-year-old female with irreparable rotator cuff tears of the right shoulder, treated with the arthroscopic shoulder superior capsular reconstruction. The general anesthesia and operation went smoothly, but the patient experienced stuffiness in the chest and shortness of breath after recovery from anesthesia. Thoracic CT scans showed spontaneous pneumothorax in the right side, which was successfully treated by the conservative treatments (oxygen therapy) according to multidisciplinary team. Prompt and accurate early-stage diagnosis is necessary in controlling postoperative complications and standardized treatment is the key to relieve the suffering. Spontaneous pneumothorax after arthroscopic shoulder surgery has been rarely reported in previous literatures.

OBJECTIVE@#To review the literature regarding diagnosis and treatment of labral tear.@*DATA SOURCES@#A systematic search was performed in PubMed using various search terms and their combinations including hip, labrum, acetabular labral tear, arthroscopy, diagnosis, and anatomy.@*STUDY SELECTION@#For each included study, information regarding anatomy, function, etiology, diagnosis, and management of acetabular labral tear was extracted.@*RESULTS@#Five hundred and sixty abstracts about anatomy, function, etiology, diagnosis, and management of acetabular labral tear were reviewed and 66 selected for full-text review. The mechanism of labral tear has been well explained while the long-term outcomes of various treatment remains unknown.@*CONCLUSIONS@#Labral tear is generally secondary to femoroacetabular impingement, trauma, dysplasia, capsular laxity, and degeneration. Patients with labral tear complain about anterior hip or groin pain most commonly with a most consistent physical examination called positive anterior hip impingement test. Magnetic resonance arthrography is a reliable radiographic examination with arthroscopy being the gold standard. Conservative treatment consists of rest, non-steroidal anti-inflammatory medication, pain medications, modification of activities, physical therapy, and intra-articular injection. When fail to respond to conservative treatment, surgical treatment including labral debridement, labral repair, and labral reconstruction is often indicated.

The mortality of conservative treatment and the risk resulting from operation for elderly patients with femoral intertrochanteric fractures are high. Safety in the perioperative period and quicker recovery should be placed at the top priority for elderly patients with hip fractures. We reported a case of 109-year-old female patient with intertrochanteric fracture who has undergone the hemiarthroplasty in our center recently. With sciatic nerve and lateral cutaneous nerve block anesthesia, she was offered the artificial femoral head replacement in the lumbar plexus block after sufficient preoperative preparation. The surgery went well with minimally invasive cut, and the patient's recovery was satisfactory.

<p><b>OBJECTIVE</b>To investigate the correlation between auto-immune antibodies and rheumatoid arthritis (RA) patients of Shen deficiency syndrome (SDS), thus providing clinical evidence for further researches on molecular biological mechanisms of RA patients of SDS.</p><p><b>METHODS</b>Totally 451 RA patients were assigned to the SDS group and the non-SDS group. Their general conditions (including gender, age, duration, and age of onset), C reactive protein (CRP), erythrocyte sedimentation rate (ESR), platelet (PLT), disease activities (DAS28), auto-antibodies [rheumatoid factor (RF), anti-CCP antibodies, anti-nuclear antibody (ANA)] were compared between the two groups.</p><p><b>RESULTS</b>(1) The scores for EST, PLT, and DAS28 were obviously higher in the SDS group than in the non-SDS group (P < 0.05, P <0. 01). (2) The level of average RF was (697.32 +/-1 061.38 IU/mL) in the SDS group, higher than that in the non-SDS group (439.91 +/- 672.24 IU/mL, P <0.01). There was no statistical difference in anti-CCP antibody between the two groups (P >0.05).(3) The ANA positive rate of RA patients was 29. 63% (120/405). It was 37.19% (74/199) in RA patients of SDS and 22. 33% (46/206) in RA patients of non-SDS, showing statistical difference between the two groups (P <0.01). (4) The odds ratio for high level RF positive and ANA positive was 1. 574 and 2. 059 folds in RA patients of SDS as high as that in RA patients of non-SDS.</p><p><b>CONCLUSIONS</b>RA patients of SDS would have higher risk of having auto-immune antibodies, fastened development, more worsen joint damage, and more poor prognosis. Its mechanisms might be closely associated with autoimmune tolerance.</p>

<p><b>OBJECTIVE</b>To study the correlation between the expression of Fcgamma receptor II b (FcgammaRII b) on B cells and rheumatoid arthritis (RA) patients of Shen deficiency syndrome (SDS).</p><p><b>METHODS</b>There were 43 RA patients, including 26 of SDS and 17 of non-SDS. The expression levels of FcgammaRII b on naive B cells, memory B cells, and plasma blasts in the peripheral blood were detected by flow cytometry. The numbers of tender joints, numbers of swollen joints, erythrocyte sedimentation rate (ESR), rheumatoid factor (RF), and disease activity score (DAS28), the correlation between the distribution of B cells and the expression level of FcgammaRII b in RA patients were analyzed. Besides, another 21 healthy volunteers were recruited as the control group.</p><p><b>RESULTS</b>The expression level of FcgammaRII b was 49.65% +/- 15.86% on memory B cells and 43.69% +/- 22.57% on plasma blasts in RA patients of SDS, significantly down-regulated when compared with those of the control group (64.03% +/- 6.01%, 66.59% +/- 10.18%, P < 0.01). The expression level of FcgammaRII b on memory B cells of RA patients of non-SDS was down-regulated more obviously when compared with that of the control group (52.70% +/- 9.52% versus 64.03% +/- 6.01%, P < 0.01). The expression level of FcgammaRII b on plasma blasts was obviously lower in RA patients of SDS than in RA patients of non-SDS (56.10% +/- 17.05%, P < 0.05). The expression level of FcgammaRII b on memory B cells was not correlated with numbers of tender joints, numbers of swollen joints, ESR, RF, or DAS28.</p><p><b>CONCLUSIONS</b>The defective immunological tolerance of B cells in RA patients of SDS might be closely correlated with down-regulation of FcgammaRII b on memory B cells and plasma blasts. There might exist genetic abnormality of FcgammaRII b gene in RA patients of SDS, thus inducing loss of autoimmunity tolerance.</p>

<p><b>OBJECTIVE</b>To report the clinical outcome of arthroscopically assisted treatment for tibial plateau fractures.</p><p><b>METHODS</b>A total of 39 patients with tibial plateau fractures were treated by arthroscopic fixation from February 2002 to December 2005, including 11 patients with bony avulsion of the anterior cruciate ligament and 19 with meniscal injury. There were 4 cases of type I fracture, 12 type II, 9 type III, 12 type IV and 2 type V according to Schatzker criteria. Firstly, the combined injuries were treated. Then the plateau fractures with the displacement over 3 mm or more were reduced and fixed. Finally, the internal fixation was observed by X-ray equipment. Postoperative management was early motion and delayed weight bearing.</p><p><b>RESULTS</b>All the fractures healed in 3 or 4 months. All patients were followed up for 1 to 5 years after operation. No case had severe complications, such as poor wound healing, infection, osteofascial compartment syndrome and osteoarthritis. According to the Rasmussen scoring system, 36 cases obtained excellent or good results and the other 3 cases had moderate clinical results. The average score was 26+/-3.</p><p><b>CONCLUSIONS</b>As an adjuvant treatment of intraarticular fractures such as tibial plateau fracture, arthroscopy has many advantages. It can treat associated intraarticular soft tissue components, visualize the chondral surface reduction, lavage the hematoma and smaller loose fragments, decrease soft tissue dissection, reduce the risk of scarring and promote rapid recovery.</p>

<p><b>OBJECTIVE</b>To evaluate the clinical result of arthroscopic anterior cruciate ligament (ACL) reconstruction with either allo- or auto- bone-patellar tendon-bone (B-PT-B) grafts.</p><p><b>METHODS</b>From February 2002 to January 2006, 142 of 187 cases of ACL ruptures who received ACL reconstruction with B-PT-B grafts were studied retrospectively. There were 93 male and 49 female whose age was from 15 to 57 years (mean 26 years). Patients were divided into 2 groups by graft selection: 38 patients with autograft and 104 with allograft. Clinical results were evaluated according to IKDC, Lysholm, Irgang and Larson scales. Sub-items of scales such as pain, swelling and laxity were specifically evaluated.</p><p><b>RESULTS</b>All of the patients were followed up with an average of 24 months (range from 6 to 43 months). All grafts were radiographically in good position at the time of follow-up. KT-1000 examination of affected knee showed less than 3 mm anterior translation difference compared with contralateral one's. Allograft group: 85 patients got normal IKDC score (81.7%). Lysholm score 82.8 +/- 8.5, Irgang score 79.2 +/- 7.3, Larson score 86.7 +/- 3.1. Autograft group: 29 patients got normal IKDC score (76.3%). Lysholm score 84.6 +/- 9.5, Irgang score 79.5 +/- 7.6, Larson score 88.9 +/- 6.8. No significant statistical difference was found between the 2 groups in the comprehend scale (P>0.05).</p><p><b>CONCLUSIONS</b>Both autograft and allograft group achieve good results, and the allograft B-PT-B could provide the similar clinical result as autograft, the preliminary result of allograft reconstruction might indicate predictable result in the future.</p>
