propionibacterium acnes frozen shoulder

The diagnosis often is made based on clinical evidence, radiographic signs, and laboratory and/or surgical findings combined. Grosso MJ, Frangiamore SJ, Ricchetti ET, Bauer TW, Iannotti JP. Propionibacterium acnes is a Gram-positive anaerobic bacillus. operative IL-6 synovial ﬂuid values (correlation = 0.61; p = 0.025) and frozen-section histologic ﬁndings (p < 0.001). Its presentation is often non-specific and can occur long after shoulder arthroplasty, leading to delay in diagnosis. frozen section should be considered when a diagnosis of infection has not been established . Association between Propionibacterium acnes and frozen shoulder: a pilot study. The patient is unable to abduct the arm beyond 30 degrees but can be assisted passively to 120 degrees. Adhesive capsulitis (AC), often termed 'frozen shoulder', is a disease where the shoulder capsule forms scar tissue or adhesions across the joint causing stiffness, pain and dysfunction. Propionibacterium (P) acnes infection of the shoulder after arthroplasty is a common and serious complication. (2017) 99:1067-72. doi: 10.1302/0301-620X.99B8.BJJ-2016-1168.R2 In addition, the appellation frozen shoulder suggests the shoulder will eventually thaw, without the need for treatment. We therefore investigated the effect of two different courses of three antibiotics (penicillin, rifampicin and linezolid) on mature P.acnes biofilms in vitro. Therapy consisted of oral antibiotics for 1-6 months. Propionibacterium is an organism that plays an important, commensal role in the ecosystem of healthy human skin, yet it can also be an opportunistic pathogen involved in clinically important soft-tissue and periprosthetic infections 1-4.In orthopaedic surgery, Propionibacterium has been linked primarily to spine 5-10 and shoulder 11-19 infections, most likely because of the proximity of these . The colonisation of the glenohumeraljoint by Propionibacterium acnes is not associatedwith frozen shoulder but is more likely to occur after an injectioninto the joint S. J. Booker, M. Boyd, S. Gallacher, J. P. Evans, C. Auckland, J. Kitson, W. Thomas, C. D. Smith Bone Joint J Aug 2017, 99-B (8) 1067-1072; DOI: 10.1302/0301-620X.99B8.BJJ-2016-1168.R2 Whether Propionibacterium acnes (P. acnes) causes surgical-site infections (SSI) after orthopedic surgery is controversial. It affects between 2-5% of the population and as much as 11-20% of diabetic patients. It is the same organism that causes acne. In addition, the appellation frozen shoulder suggests the shoulder will eventually thaw, without the need for treatment. Propionibacterium acnes: an underestimated etiology in the pathogenesis of osteoarthritis? Over the past decade, however, there has been a growing body of literature suggesting that Propionibacterium acnes infection may play a significant role in a variety of pathological conditions affecting the native shoulder, most notably frozen shoulder [4,5]. J Bone Joint Surg Am. The one shoulder with an arthroscopic debridement had a Staphylococcus aureus infection. Bone Joint J. Eight of the 10 patients had positive findings on extended culture in their shoulder capsule and, in six of these, Propionibacterium acnes was present. propionibacterium acnes (p acnes) is a gram-positive, non-spore-forming, anaerobic bacillus found in the cutaneous, upper respiratory, and digestive mucosae. (OBQ18.107) A 65-year-old male underwent a right total shoulder arthroplasty procedure 5 years ago and is presenting with increasing shoulder pain and weakness. 1 C. acnes is often thought to be clinically significant, but its ubiquity as common skin flora and frequent . Propionibacterium acnes was present. The purpose of this study was to determine the sensitivity of frozen section histology in identifying patients with Propionibacterium acnes infection during revision total shoulder arthroplasty and investigate various diagnostic thresholds of acute . It has emerged as a major pathogen responsible for postoperative shoulder infections after both arthroscopy and arthroplasty procedures. However, PJI caused by C acnes rarely manifests as overt clinical, laboratory, or imaging features. Propionibacterium acnes Propionibacterium acnes (P. acnes) is a non-spore-forming, anaerobic, gram-positive bacillus. The colonisation of the glenohumeral joint by propionibacterium acnes is not associated with frozen shoulder but is more likely to occur after an injection into the joint. Conclusions The findings mean that we must reject the null hypothesis that there is no relationship between infection and frozen shoulder. Propionibacterium acnes were identified in five, coagulase-negative Staphylococcus in two, and Staphylococcus saccharolyticus in one shoulder. Evidence regarding the influence of the implant material on IAI caused by C. acnes . Patients and Methods. acne. The purpose of this study was to determine the sensitivity of frozen section histology in identifying patients with Propionibacterium acnes infection during revision total shoulder arthroplasty and investigate various diagnostic thresholds of acute inflammation that may improve frozen section performance. Propionibacterium. Eradication of P. acnes with preprocedural skin decontamination is difficult as the bacterium resides deep within confines of the pilosebaceous glands [5-8]. Sensitivity of Frozen Section Histology for Identifying Propionibacterium acnes Infections in Revision Shoulder Arthroplasty. It is most . It is a common skin commensal, but it has also been shown to be involved in the pathogenesis of acne vulgaris [ 2 ]. Propionibacterium acnes (P. acnes) is a gram-positive anaerobic bacillus commonly isolated from the flora of the face, chest, and axilla region. 80% of patients with negative cultures improved . Propionibacterium acnes is a facultative anaerobic Gram-positive rod, abundant on the human skin, and mainly associated with the sebaceous glands of the shoulder and axilla [37]. Cutibacterium Acnes (C.acnes) is a non-spore forming aerotolerant gram-positive bacterium of low virulence that has long been established as a cause of soft tissue and skin infections.It is a commonly found commensal of the skin and sebaceous follicles around the face, neck, shoulders and back [1,2,3,4,5,6].There has been a suggested link between colonisation of the shoulder joint with C.acnes . Bone Joint J England 99-B:1067-1072 J Bone Joint Surg Am. Prosthetic shoulder infection is a potentially devastating condition and is most commonly associated with Cutibacterium acnes. The most prevalent cause of patient infections is Cutibacterium acnes(formerly Proprionibacterium acnes), a commensal skin bacterial species. The purpose of this study was to determine the sensitivity of frozen section histology in identifying patients with Propionibacterium acnes infection during revision total shoulder arthroplasty and investigate various diagnostic thresholds of . 52. What are tendonitis, calcaneal inflammation and shoulder syndrome? This particular bacteria lives in the pores and hair follicles in the skin of your shoulder, neck and head region. 1 INTRODUCTION. While the majority of IAI in context with C. acnes has been reported in shoulder arthroplasty cases of C. acnes on osteosynthetic implant material have been identified requiring implant removal and an average of 5.7 months of adjuvant antibiotic treatment .

It has emerged as a major pathogen responsible for postoperative shoulder infections after both arthroscopy and arthroplasty procedures. 2, 6, 11 traditionally considered nonpathogenic, 8, 12 this anaerobe has been reported to be responsible for severe infections at various body sites, including central nervous system … 18 It can cause skin infections such as Acne vulgaris. septic arthritis following shoulder arthroplasty has been well documented [1], but native joint septic arthritis may be under recognized, undiagnosed, and consequently falsely attributed to orthopedic surgery. repair of shoulder, arthroplasty), 81.88 (reverse total shoul-der arthroplasty), and 81.97 (revision joint replacement upper extremity). It is a human commensal organism, primarily found in skin and superficial mucosal sites, with a predilection for pilosebaceous follicles that exist in the upper body such as the shoulder region [ 8-10 ]. We present the case of an 82-year-old man with a surgical site erythema . BACKGROUND: Propionibacterium acnes is a clinically relevant pathogen with total shoulder arthroplasty. [32] , [34] , [41] In addition to the high prevalence of C acnes found during primary arthroplasty in native shoulders, [9] , [24] , [33] P. acnes is a "powerful nonspecific immune stimulant" which probably does trigger some cases of frozen shoulder, failures of prostheses, some arthritis, and perhaps even sciatica. There has been no sign of infection at a mean followup of 8.7 years (range, 5-11.8 years). Over the past decade, however, there has been a growing body of literature suggesting that Propionibacterium acnes infection may play a significant role in a variety of pathological conditions affecting the native shoulder, most notably frozen shoulder [4,5].

This is a very important article in that it suggests the presence of propionibacterium in previously unoperated shoulders with arthritis and furthermore that 'aseptic' failures of shoulder arthroplasty may, in fact, be related to indolent infections with this slow growing organism. Propionibacterium acnes is a Gram-positive, rod-shaped, slow-growing bacterium. admin-June 16, 2021 0. Propionibacterium acnes (33%), three coagulase-negative Staphylococcus species . 2014 Oct;6 (4):257-61. doi: 10.1177/1758573214533664. Cutibacterium acnes ( C acnes, formerly Propionibacterium acnes) is a low-virulent pathogen associated with high rates of infection in shoulder arthroplasty . 19 Propionibacterium acnes is difficult to culture and its role in infections such as may occur after shoulder joint . It is a common contaminant of clinical specimens, presumably from the skin of patients or attendants. Booker SJ, Boyd M, Gallacher S, Evans JP, Auckland C, Kitson J, Thomas W, Smith CD (2017) The colonisation of the glenohumeral joint by Propionibacterium acnes is not associated with frozen shoulder but is more likely to occur after an injection into the joint. cause of pain following shoulder arthroplasty because of its severe implications. In the two patients treated with open debridement, the microorganisms cultured were Staphylococcus aureus and Propionibacterium acnes. Vials were then stocked and frozen at −70°C. Furthermore, in six stiff patients without any notable radiological signs cultures were positive. Case Presentation. Periprosthetic joint infection (PJI) is one of the most frequent reasons for painful shoulder arthroplasties and revision surgery of shoulder arthroplasties. Pre-operative culture of unprepared skin can be indicative of underlying joint infection in shoulder arthroplasty revision. As opposed to PJI in the hip and knee, conﬁrming the diagnosis of shoulder PJI can often be difﬁ-cult because many infections are caused by fastidious or-ganisms.19 Cutibacterium (formerly Propionibacterium) acnes is the most common cause of shoulder PJI.21 . The diagnosis is often delayed with impact on long-term outcomes. Propionibacterium acnes. 2014;96:442-7 ↑ Schneeberger AG, Yian E, Steens W. Injection-induced low-grade infection of the shoulder joint: preliminary results. Shoulders are prone to infection caused by an organism known as Propionibacterium acnes shoulder infection. In the shoulder Propionibacterium acnes (P. acnes) is the most common bacteria that causes problems. C. acnes was first identified as a commensal skin microorganism and it is often localized around sebaceous glands. The patient denies any recent falls, fevers, or chills. Booker SJ, Boyd M, Gallacher S, Evans JP, Auckland C, Kitson J, et al. The unique characteristics of this microorganism make the diagnosis of infection difficult. There is special emphasis on indolent infections related to Propionibacterium acnes and the challenges associated with the diagnosis and management of this pathogen. Patients presented with classical post-operative frozen shoulder symptoms, resistant to usual treatments. Propionibacterium acnes is increasingly recognized as a cause of delayed infection after spinal instrumentation or shunting for hydrocephalus. What is a torn swivel cuff? 23 Its role in post-operative infection is probably simply because it's an endemic skin critter, nearly impossible to completely eliminate from the site of any puncture. Pure cultures of Propionibacterium acnes were isolated from synovial tissue and synovial fluid speci- mens collected from the same joint after a 4-month interval. Aims Our aim was to investigate the prevalence of Propionibacterium (P.) acnes in the subcutaneous fat and capsule of patients undergoing shoulder surgery for frozen shoulder or instability. We present three cases of . Cutibacterium acnes) infections are of recent interest as causative bacteria in prosthetic joint infections particularly of the shoulder. There are steps that you can take to help prevent surgical infections. P acnes isolates obtained from positive intraoperative cultures were frozen for long-term storage after initial culture analysis was completed and immediately following revision shoulder arthroplasty. The well described ability of Cutibacterium acnes to manipulate the cellular response and therefore its role in chronic inflammation may explain the mechanical symptoms giving a classic postoperative frozen shoulder impression [11, 24, 25]. Matthew J. Grosso, Salvatore J. Frangiamore, Eric T. Ricchetti, Thomas . Patients and methods A total of 46 patients undergoing either an arthroscopic capsular release or stabilisation had biopsies taken from the subcutaneous fat and capsule of the shoulder at the time of surgery. Propionibacterium acnes was the most prevalent organism. The diagnosis of deep infection after shoulder arthroplasty remains a challenge, particularly for low-grade bacteria such as Cutibacterium acnes (C. acnes, previously Propionibacterium acnes). Propionibacterium acnes(P. acnes) is a gram-positive anaerobic bacillus commonly isolated from the flora of the face, chest, and axilla region.

In addition, a less common bacteria called Propionibacterium acnes is often associated with shoulder infections. Propionibacterium acnes: an underestimated etiology in the pathogenesis of osteoarthritis? This is a very important article in that it suggests the presence of propionibacterium in previously unoperated shoulders with arthritis and furthermore that 'aseptic' failures of shoulder arthroplasty may, in fact, be related to indolent infections with this slow growing organism. Patients present with atypical symptoms such as stiffness or failure to improve shoulder function. Biofilm development by this organism has recently been demonstrated. We have developed a polymerase chain reaction (PCR)-restriction fragment length polymorphism (RFLP) approach that sensitively and specifically identifies P . Sensitivity of frozen section histology for identifying Propionibacterium acnes infections in revision shoulder arthroplasty.
