A combined debridement, antibiotics, and implant retention (DAIR) procedure with flap coverage for acute soft tissue defects following total knee arthroplasty: a retrospective study.

Acute soft tissue defects, such as persistent drainage, wound dehiscence, or necrosis, following total knee arthroplasty (TKA) can lead to the devastating complication of deep infection. Typically, when a medium-sized defect is present, a gastrocnemius flap is widely employed for soft tissue reconstruction due to its low morbidity and favourable functional outcomes. When facing this situation, we should consider associating the coverage treatment with a debridement, antibiotics, and implant retention (DAIR) surgery procedure, in order to treat a possible acute infection, even when the diagnosis of infection is not clear. We performed a retrospective study to compare TKA outcomes in patients with DAIR and flap procedures in the same surgical act against those who had received an isolated flap procedure for soft tissue reconstruction after an acute surgical wound defect. Patients had been identified from a prospectively collated TKA database. Between 2005 and 2021, 18 patients met our inclusion criteria, with a mean follow-up of approximately 8years. A medial gastrocnemius flap procedure was performed for 15 patients (83 %). We compared the rates of infection clearance between the two groups. No differences in comorbidities or risk factors were observed between both groups. In the combination treatment group, 66.6 % of patients healed after treatment compared to 33.3 % in the isolated flap group. Although no significant statistical differences were found, the association of DAIR with the muscle flap procedure is highly recommended in the treatment of acute soft tissue defects after TKA. Further studies with larger sample sizes are necessary to extrapolate these findings to the general population.

3D-Printed Metaphyseal Cones in Revision Total Knee Arthroplasties: Excellent Survivorship of 740 Cones at 5 Years.

Porous metaphyseal cones are frequently utilized during revision total knee arthroplasty (TKA) procedures. The purpose of the present study was to evaluate 3D-printed metaphyseal cones used for revision TKA, with specific emphasis on implant survivorship, radiographic appearance, and clinical outcomes after short-term follow-up. We identified 740 cones (498 tibial, 242 femoral) that had been inserted during 533 revision TKA procedures that had been performed at a single tertiary care academic institution. Aseptic loosening (n = 199), periprosthetic joint infection (PJI) (n = 183), and instability (n = 84) were the most common reasons for the index revision. Type-2B or 3 bone loss was present in 67% of the knees. The mean age was 66 years, the mean body mass index was 34 kg/m2, and 55% of the patients were female. Serial radiographs were reviewed. The mean duration of follow-up was 4 years. The 5-year cumulative incidence of cone revision for aseptic loosening was 1% (95% confidence interval [CI], 0% to 3%). The 5-year cumulative incidence of any cone revision or removal was 6% (95% CI, 4% to 9%). In total, 37 cones (19 femoral, 18 tibial) were revised, with PJI (n = 23; 14 recurrent), periprosthetic femoral fracture (n = 3), arthrofibrosis (n = 3), and aseptic loosening of the femoral component and femoral cone (n = 3) as the most common reasons for cone revision. The 5-year cumulative incidence of any TKA re-revision was 14% (95% CI, 11% to 18%). There were a total of 67 re-revisions, with PJI (n = 38), persistent drainage (n = 6), and extensor mechanism disruption (n = 3) being the most common reasons. Radiographically, 2 unrevised femoral cones and 1 unrevised tibial cone appeared to be possibly loose; all 3 cones were in knees with distal femoral replacements or hinged constructs. This large series showed that 3D-printed titanium metaphyseal cones were very durable at short-term follow-up, with a 5-year cumulative incidence of cone revision for aseptic loosening of 1%. PJI was the most common reason for cone revision and any revision. Therapeutic Level IV. See Instructions for Authors for a complete description of levels of evidence.

Antibiotic calcium sulphate beads lower the bacterial burden and prevent infection in a mouse model of periprosthetic joint infection.

Delayed postoperative inoculation of orthopaedic implants with persistent wound drainage or bacterial seeding of a haematoma can result in periprosthetic joint infection (PJI). The aim of this in vivo study was to compare the efficacy of vancomycin powder with vancomycin-eluting calcium sulphate beads in preventing PJI due to delayed inoculation. A mouse model of PJI of the knee was used. Mice were randomized into groups with intervention at the time of surgery (postoperative day (POD) 0): a sterile control (SC; n = 6); infected control (IC; n = 15); systemic vancomycin (SV; n = 9); vancomycin powder (VP; n = 21); and vancomycin bead (VB; n = 19) groups. Delayed inoculation was introduced during an arthrotomy on POD 7 with 1 × 105 colony-forming units (CFUs) of a bioluminescent strain of Staphylococcus aureus. The bacterial burden was monitored using bioluminescence in vivo. All mice were killed on POD 21. Implants and soft-tissue were harvested and sonicated for analysis of the CFUs. The mean in vivo bioluminescence in the VB group was significantly lower on POD 8 and POD 10 compared with the other groups. There was a significant 1.3-log10 (95%) and 1.5-log10 (97%) reduction in mean soft-tissue CFUs in the VB group compared with the VP and IC groups (3.6 × 103 vs 7.0 × 104; p = 0.022; 3.6 × 103 vs 1.0 × 105; p = 0.007, respectively) at POD 21. There was a significant 1.6-log10 (98%) reduction in mean implant CFUs in the VB group compared with the IC group (1.3 × 100 vs 4.7 × 101, respectively; p = 0.038). Combined soft-tissue and implant infection was prevented in 10 of 19 mice (53%) in the VB group as opposed to 5 of 21 (24%) in the VP group, 3 of 15 (20%) in the IC group, and 0% in the SV group. In our in vivo mouse model, antibiotic-releasing calcium sulphate beads appeared to outperform vancomycin powder alone in lowering the bacterial burden and preventing soft-tissue and implant infections.

Efficacy of Intrawound Vancomycin in Prevention of Periprosthetic Joint Infection After Primary Total Knee Arthroplasty: A Prospective Double-Blinded Randomized Control Trial

BackgroundPeriprosthetic joint infection (PJI) after total knee arthroplasty (TKA) is a devastating complication. Intrawound vancomycin powder has been shown to reduce infection rates in spine surgery, but its role in arthroplasty remains controversial. This prospective randomized control trial aimed to evaluate the efficacy of intrawound vancomycin in preventing PJI after primary TKA. MethodsA total of 1,022 patients were randomized to the study group (n = 507, who received 2 grams intrawound vancomycin powder before arthrotomy closure) or to the control group (n = 515, no local vancomycin) with a minimum follow-up of 12-months. The primary outcome was the incidence of PJI or surgical site infection (SSI). Secondary outcomes included associated minor complications such as stitch abscess, persistent wound drainage, and delayed stitch removal. Other parameters evaluated include reoperation rates and incidences of nephrotoxicity. ResultsThe overall infection rate in 1,022 patients was 0.66%. There was no significant difference in PJI rate in the study group (N = 1; 0.2%) versus the control group (N = 3; 0.58%), P = .264. Reoperation rates in the study group (N = 4; 0.78%) and control (N = 5; 0.97%), and SSI rates in the study (N = 1; 0.2%) and control groups (N = 2; 0.38%) were comparable. The Vancomycin cohort, however, demonstrated a significantly higher number of minor wound complications (n = 67; 13.2%) compared to the control group (n = 39; 7.56%, P < .05). Subgroup analysis showed diabetics in the study group to also have a higher incidence of minor wound complications (24 [14.1%] versus 10 [6.2%]; P < 05]. Multivariate analyses found that vancomycin use (odds ratio = 1.64) and smoking (odds ratio = 1.85) were associated with an increased risk of developing minor wound complications. No cases of nephrotoxicity were reported. ConclusionsIntrawound vancomycin powder does not appear to reduce PJI/SSI rate in primary total knee arthroplasties, including high-risk groups. Although safe from a renal perspective, intrawound vancomycin was associated with an increase in postoperative aseptic wound complications. Intrawound vancomycin may not be effective in reducing the rate of PJI in primary TKA.

Persistence of Urachus in A 7-Month-Old Male Patient with Surgical Resolution: Case Report

Introduction: Patent urachus refers to a rare condition called urachus anomaly. These conditions are caused by the failure of the normal fetal tissue used to empty the fetal bladder to degenerate. Some of these urachal abnormalities are obvious at birth, while others are more subtle and are not diagnosed until adulthood or are discovered only incidentally after imaging for other reasons. Urachal anomalies in children with wet umbilical cord, persistent drainage, recurrent urinary tract infections, and recurrent umbilical cord infections require accurate and timely diagnosis to help relieve symptoms, prevent recurrent serious infections, and ensure timely treatment. Clinical case: The case of a 7-month-old male patient is presented. The mother reports umbilical granuloma of several months of evolution. He goes to a doctor where he suggests an ultrasound examination that rules out persistence of urachus. Mass in umbilical region persists, which is why she comes again. Evolution: By laparoscopic vision, umbilical hernia plus persistence of urachus is evident, findings such as the presence of indirect bilateral inguinal hernia are found. After surgery, the patient recovered satisfactorily. Conclusions: Diagnosis of urachal anomalies can be elusive, but continued drainage of the umbilical cord is a concern in the case of urachal anomalies. Although this condition is usually an isolated finding, the possibility of posterior urethral valves in infants with a patent urachus should not be ruled out.

Different mechanisms for persistent and residual left-to-right shunt after transcatheter sinus venosus defect closure and their management.

Transcatheter closure of superior vena cava (SVC) form of sinus venosus defects (SVDs) using covered stents is emerging as an alternative to surgery in the current decade. A covered stent placed in the cavoatrial junction creates a roof for the right upper pulmonary vein (RUPV) that stops the left-to-right shunt and redirects the vein to the left atrium. While surgical literature has clearly documented the incidence of stenosis of SVC and RUPV, sinus nodal dysfunction, and persistent residual shunts following surgical correction, it is imperative to have similar data after this new transcatheter intervention on the incidence of complications and follow-up outcomes. Since patients with pretricuspid shunts are often clinically asymptomatic, correction is primarily performed to prevent a persistent right heart volume overload and allow remodeling of the heart chambers. Any residual left-to-right shunt after a correction will result in persistent right heart dilatation. Residual flows can result from various mechanisms, including lack of apposition of the covered stent to the free edge of the SVD, fabric breach, and persistent anomalous drainage of additional right-sided pulmonary veins that drain very high in the SVC or can be due to a coexistent defect in the oval fossa. This review analyzes the different mechanisms, explains the transesophageal and angiographic images for each one, and offers solutions tailored for various reasons. Different mechanisms warrant different treatment principles. A solution for residual shunt from one mechanism may not be appropriate for residual flow through another mechanism. A thorough understanding would aid the operator in effective interventions for these SVDs.

Chest wall abscess and costochondritis due to Salmonella enterica serotype Choleraesuis: a case report

BackgroundSalmonella enterica serotype Choleraesuis infections usually cause self-limited gastrointestinal diseases. Extra-abdominal infections are often secondary to bacteremia in immunocompromised individuals and are relatively rare in immunocompetent hosts.Case presentationA 65-year-old Caucasian female initially presented to the thoracic surgery clinic due to a poorly healing wound on her chest. Her condition started after a mechanical fall hitting her chest with interval development of a tender lump that later spontaneously drained. A chest computed tomography scan with intravenous contrast demonstrated an abnormal infiltration with small foci of fluid and air consistent with a small abscess anterior to the left seventh costal cartilage. Aspirate culture of the abscess grew S. enterica serotype Choleraesuis susceptible to ampicillin and trimethoprim/sulfamethoxazole. The patient had no prior history of signs or symptoms of gastrointestinal infection. Blood cultures were negative. With a background of penicillin allergy, she was treated with trimethoprim/sulfamethoxazole, and later with ceftriaxone due to persistent drainage of the wound. Follow-up chest computed tomography scan with intravenous (IV) contrast showed continued abnormal findings previously seen in the computed tomography scan with the appearance of a sinus tract. The patient subsequently underwent surgical debridement and partial resection of the left seventh costochondral cartilage and excision of the fistula. She had an uneventful recovery and complete resolution of her condition.ConclusionWe report a rare case of chest wall abscess with associated costochondritis due to S. enterica serotype Choleraesuis in a patient with no evidence of immunodeficiency nor history of bacteremia. Extraintestinal infections due to Salmonella without documented bacteremia have been previously reported in the literature. History of local trauma to the affected area might contribute to the seeding of infection. Diagnosis is often accomplished by clinical evaluation and culture of the affected area. Treatment often involves targeted antibiotic therapy but may require surgical intervention to achieve source control and cure.

WHAT IS THE COMPLIANCE REGARDING THROMBOPROPHYLAXIS IN POSTOPERATIVE ARTHROPLASTY PATIENTS IN A TERTIARY HOSPITAL IN SOUTH AFRICA?

Total Joint Arthroplasty (TJA) is a successful orthopaedic procedure allowing dramatic clinical and functional improvements. Globally, there's been an increase in demand and performed cases associated with an increase in complications. Subsequently, focus on the prevention of complications has become important worldwide. The incidence of venous-thrombolic events (VTE) despite great attention has not diminished despite much investigation. A balance between efficacy and safety from the available agents is essential. Low molecular weight heparin (LMWH) has been commonly used, but oral anti-coagulants have become more popular. The aim of this study was to assess the adherence LMWH and the effectiveness and safety of preventing VTE in post-operative arthroplasty patients in a South African setting.We conducted a prospective cohort study that included hip and knee, primary and revision, arthroplasty patients who received thromboprophylaxis with one daily injection of LMWH for 14 days post discharge. Patients who omitted 1 or more doses during the follow up period were classified as “non adherent”. A questionnaire was used at follow up visits at least 6 weeks post-operatively.100 consecutive patients were followed up. The mean age of patients was 63.45 years. There were 68 % female patients. There was a 92% compliance rate. 60 % of patients had the injection administered by a family member, 38 % administered it themselves and 2 % had the injection administered by health professionals. Venous thromboembolic events were confirmed in 5 % at 7.86 days after surgery. Three patients had persistent wound drainage after surgery, however, none required reoperation or readmission.Compliance with LMWH is high and is comparable with oral agents. It is effective in preventing VTE and safe with regards to bleeding and wound complications in a South African setting. Patient education regarding medications may improve compliance of the medication.

Exploring the role of copper and zinc in chronic otitis media: A novel spectrofluorometric method for precise determination and association study

Chronic otitis media is a common condition characterized by fluid accumulation in the middle ear, leading to a perforated eardrum and persistent middle ear drainage. Despite its impact on global health, the role of heavy metals, particularly copper and zinc, in its development and progression remains understudied. Herein, a spectrofluorometric method was developed for the precise determination of copper and zinc in human plasma samples and investigate their association with chronic otitis media. The method involves the use of the fluorescent probe 6,7-dihydroxy-4-phenylcoumarin to selectively quantify copper through fluorescence quenching and zinc through fluorescence enhancement with a remarked bathochromic shift. The method was validated and exhibited good linearity over a concentration range of 100–3000 ng/mL for copper and 200–5000 ng/mL for zinc. Application of the method to healthy volunteers and patients with chronic otitis media revealed significantly decreased copper and zinc levels in patients with chronic otitis media compared to the healthy individuals. These findings shed light on the involvement of copper and zinc in the pathogenesis of chronic otitis media and open avenues for additional treatment approaches.

Review of patients discharged post thoracic surgery with chest drain in situ and nurse-based follow-up clinic.

Persistent air leaks and prolonged drainage are recognized complications of thoracic surgery, increasing hospital stay and costs. Patients can be discharged with a chest drain and followed up in a nurse-led clinic. We reviewed such patients and the rate of readmission after discharge to assess the effectiveness of the drain follow-up clinic. We conducted a retrospective review of our prospective database spanning 22 months, from March 2019 to January 2021. The analysis focused on the indication and duration of chest drainage, complications, and readmission for any reason. 62 patients (representing 5% of all thoracic surgery patients) were discharged with a chest drain. The median age was 67 years (range 22-85 years), with 24 females and 38 males. 52% underwent video-assisted thoracoscopic surgery, 27% had a thoracotomy, and 21% had bedside chest drain insertion. Following discharge, the median duration of chest drainage was 11 days [interquartile range (IQR) 7-18.75 days]. Patients had 106 review episodes in the ward-based nurse-led clinic. The indications were prolonged air leak (71%; 72 clinic reviews), persistent fluid drainage following empyema evacuation (16%; 24 clinic reviews), and persistent fluid drainage for simple effusion (13%; 10 clinic reviews). The median length of drain stay was 30 days (IQR 19.75-54 days) for empyema, 10 days (IQR 6-16 days) for air leak, and 8 days (IQR 6.5-12 days) for simple effusion. 9 patients required readmission (14.5%), and empyema had developed in 3 patients (4.8%). Patients discharged with a chest drain in place can be followed up in a dedicated ward-based nurse-led monitoring clinic for optimal quality of care.

NAVIO RATKA shows similar rates of hemoglobin-drop, adverse events, readmission and early revision vs conventional TKA: a single centre retrospective cohort study.

Despite widespread adoption of NAVIO robotic-assisted total knee arthroplasty (NAVIO RATKA) in clinical practice, clinical outcome in terms of adverse events and complications remains unclear. The purpose of this study was to compare adverse events, length of stay, surgical time, hemoglobin drop, early readmission rate and revision rate between conventional TKA (CTKA) and NAVIO RATKA. This single-centre retrospective cohort analysis compared 230 NAVIO RATKA patients to 489 CTKA patients with a minimal follow-up of 12 months. Baseline demographic and comorbidity parameters were collected, as well as length of stay, revision rate and reason for revision, early readmission rate (< 6w) and reason for readmission, post-operative hemoglobin levels, adverse events, surgical time and operating room time. Data were compared using Mann-Whitney U test for continuous data without normal distribution and ordinal data, categorical variables were compared using the Chi-square or Fisher exact test. There were no clinically relevant baseline demographic or comorbidity differences between groups. CTKA had shorter length of stay than NAVIO RATKA (5.0 days vs 5.4 days, p = 0.010) but trended towards a higher reoperation rate (4.1% vs 1.7%, p = .144, n.s). No differences were found in hemoglobin drop, readmission rate or overall incidence of adverse events, but CTKA showed more hematoma formation (1.6% vs 0%, p = .044) and higher incidence of periprosthetic joint infection (PJI) (1% vs 0%, p = n.s.), whilst NAVIO RATKA showed more periprosthetic fractures and persistent wound drainage (0.4% vs 2.2%, p = .038 and 0.6% vs 4.3%, p = .001, respectively). Surgical time remained significantly longer in NAVIO RATKA during all 230 cases (87 min vs 67.6 min) and showed a continuous downward trend. This study further validates the usage of NAVIO RATKA as a safe method to perform TKA, with comparable short term outcomes to CTKA in terms of early revisions and adverse events. Surgeons should be mindful of the differing adverse event profile in NAVIO RATKA and adjust their patient selection accordingly to ensure optimal outcomes. In addition, surgeons using NAVIO RATKA should expect a linear learning curve and a surgical time exceeding that of CTKA. Level III (therapeutic retrospective cohort study).

Complex Case of Skull Base Osteomyelitis Secondary to Chronic Otitis Media.

We present a case of a 58-year-old male with type II diabetes managed with metformin and insulin, who presented to the clinic with left chronic otitis media, persistent drainage, a stenotic meatus, and a prior history of 3 canal wall-down mastoidectomies and antibiotic therapy. A revision tympanoplasty with mastoidectomy was performed, and during the postoperative period, the patient had persistent pain and otorrhea, which were managed with opioids and several courses of antibiotic therapy. After symptoms persisted, imaging and culture ultimately led to the diagnosis of fungal skull base osteomyelitis, which was eventually treated successfully. While these complications are rare, their likelihood is increased with treatment delay and in the immunocompromised patient. Close management of immunocompromised patients, including diabetic patients, is vital in identifying complications early to aid in timely diagnosis and treatment to lead to the best possible outcome.

Clinical and laboratory predictors for prosthetic joint infection within the first postoperative days following primary total hip and knee arthroplasty

PurposeTo identify clinical and laboratory predictors for low- and high-grade prosthetic joint infection (PJI) within the first postoperative days following primary total hip/knee arthroplasty (THA/TKA).MethodsInstitutional bone and joint infection registry of a single osteoarticular infection referral centre was reviewed to identify all osteoarticular infections treated between 2011 and 2021. Among them were 152 consecutive PJI (63 acute high-grade PJI, 57 chronic high-grade PJI, and 32 low-grade PJI) who also had primary THA/TKA performed at the same institution, which were retrospectively analyzed with multivariate logistic regression and covariables.ResultsFor each additional day of wound discharge, persistent wound drainage (PWD) predicted PJI in the acute high-grade PJI group with odds ratio (OR) 39.4 (p = 0.000, 95%CI 1.171–1.661), in the low-grade PJI group with OR 26.0 (p = 0.045, 95%CI 1.005–1.579), but not in the chronic high-grade PJI group (OR 16.6, p = 0.142, 95%CI 0.950–1.432). The leukocyte count product of pre-surgery and POD2 >100 predicted PJI in the acute high-grade PJI group (OR 2.1, p = 0.025, 95%CI 1.003–1.039) and in the chronic high-grade PJI group (OR 2.0, p = 0.018, 95%CI 1.003–1.036). Similar trend was also seen in the low-grade PJI group, but was not statistically significant (OR 2.3, p = 0.061, 95%CI 0.999–1.048).ConclusionsThe most optimal threshold value for predicting PJI was observed only in the acute high-grade PJI group, where PWD >three days after index surgery yielded 62.9% sensitivity and 90.6% specificity, whereby the leukocyte count product of pre-surgery and POD2 >100 showed 96.9% specificity. Glucose, erythrocytes, hemoglobin, thrombocytes, and CRP showed no significant value in this regard.

Prevalance of unsafe ear in patients presenting with chronic ear discharge

Objective: The purpose of this study was to determine the frequency of atticoantral/unsafe chronic suppurative otitis media in patients with chronic ear discharge. Materials and Methods: This Cross-sectional study was conducted in the department of ENT and Head and Neck Surgery, Hayatabad Medical Complex and Department of ENT, Naseerullah Khan Babar memorial Hospital, Peshawar from August 2018 to February 2019. In this study 199 patients were enrolled with consecutive sampling. Detailed demographic data like history and physical examination were taken from patients. All patients were subjected to detailed otoscopic examination and pure tone audiometery by a consultant. A detailed performa was designed in which all information of the patients like name, age, gender, duration of symptoms and CSOM were recorded by SPSS analysis. Results: With a standard deviation of ± 10.334, the average age of participants in this study was 29 years. There were more males than women among the patients present, with 60% of them being men. Twelve percent of patients with chronic discharge developed CSOM, compared to 90% of those who didn't have the condition at all. Conclusion: Our study shows that individuals who come with persistent ear drainage frequently have hazardous ears.

Persistent lymphoceles can affect scarring and closure of the urethral stump following radical cystectomy. While this is a rare occurrence, traditional management includes endoscopic fulguration of the proximal urethral stump. Herein, we aim to describe a novel endoscopic technique for urethral stump closure in a patient with persistent urethral drainage in the setting of a recurrent pelvic lymphocele following radical cystectomy. METHODS: A 60-year-old male with history of muscle invasive small cell carcinoma of the bladder underwent robotic assisted radical cystectomy with pelvic and para-aortic lymph node dissection and Indiana pouch creation in November 2021 following neoadjuvant chemotherapy. He developed a symptomatic lymphocele in February 2022 with persistent urethral drainage. He underwent aspiration of the pelvic fluid collection and endoscopic urethral fulguration without improvement. He was then referred for second opinion, where he elected to proceed with endoscopic fulguration and closure using a laparoscopic suture device (RD-180; LSI Solutions, Rochester, NY) and novel endoscopic sheath (JNW UrtractTM; LSI Solutions, Rochester, NY). Prior to surgery, a pigtail drain was placed in the pelvic fluid collection. The proximal stump was fulgurated using the bipolar plasma band via a 27 Fr cystourethroscope (Olympus Surgical Technologies America, Westborough, MA) to facilitate scarring. The stump was closed using the RD-180 under direct visualization in a figure of eight fashion both proximally at the opening and 1cm distally. Knots were fashioned using the Ti-Knot fastener (LSI Solutions, Rochester, NY). RESULTS: Total operative time was 37 minutes and the patient discharged same day. His follow-up CT scan locally 2 months postoperatively demonstrated resolution of the pelvic fluid collection, and his drain was removed. He remains asymptomatic without recurrence of urethral drainage 4 months postoperatively. CONCLUSIONS: To our knowledge, this is the first described case of endoscopic closure of a urethral stump in the setting of persistent drainage from a pelvic lymphocele. Fulguration with endoscopic closure using a novel device is both a safe and efficacious alternative to performing urethral fulguration alone.

Production in peatlands: Comparing ecosystem services of different land use options following conventional farming

Majority of Dutch peatlands are drained and used intensively as grasslands for dairy farming. This delivers high productivity but causes severe damage to ecosystem services supply. Peatland rewetting is the best way to reverse the damage, but high water levels do not fit with intensive dairy production. Paludiculture, defined as crop production under wet conditions, provides viable land use alternatives. However, performance of paludiculture is rarely compared to drainage-based agriculture. Here, we compared the performances of six land use options on peatland following a gradient of low, medium, and high water levels, including conventional and organic drainage-based dairy farming, low-input grasslands for grazing and mowing, and high-input paludiculture with reed and Sphagnum cultivation. For each land use option, we conducted environmental system analysis on model farm system defined by a literature based inventory analysis. The analysis used five ecosystem services as indicators of environmental impacts with a functional unit of 1-ha peat soil. Ecosystem services included biomass provisioning, climate, water, and nutrient regulation, and maintenance of habitat. Results showed that drainage-based dairy farming systems support high provisioning services but low regulation and maintenance services. Organic farming provides higher climate and nutrient regulation services than its conventional counterpart, but limited overall improvement due to the persistent drainage. Low-intensity grassland and paludiculture systems have high regulation and maintenance services value, but do not supply biomass provisioning comparable to the drainage-based systems. Without capitalizing the co-benefits of regulation and maintenance services, and accounting for the societal costs from ecosystem disservices including greenhouse gas emission and nitrogen pollution, it is not likely that the farmers will be incentivized to change the current farming system towards the wetter alternatives. Sustainable use of peatlands urges fundamental changes in land and water management along with the financial and policy support required.

Bilateral Chronic Active Otitis Media associated with Tonsillitis and Allergic Rhino Conjunctivitis in a 26 month old boy

Chronic Otitis media is a permanent abnormality on the tympanic membrane following a long-standing middle ear infection emanating from a previous acute infection. Patients usually present with persistent drainage from the middle ear. It may be accompanied by complications such as septicemia, meningitis, brain abscess, facial paralysis, and deafness in children. Associated rhino-conjunctivitis is not common but this case presented with clinical features of chronic active otitis media, tonsillitis, and allergic rhino-conjunctivitis.

Wound drainage after arthroplasty and prediction of acute prosthetic joint infection: prospective data from a multicentre cohort study using a telemonitoring app.

Background: Differentiation between uncomplicated and complicated postoperative wound drainage after arthroplasty is crucial to prevent unnecessary reoperation. Prospective data about the duration and amount of postoperative wound drainage in patients with and without prosthetic joint infection (PJI) are currently absent. Methods: A multicentre cohort study was conducted to assess the duration and amount of wound drainage in patients after arthroplasty. During 30postoperative days after arthroplasty, patients recorded their wound status in a previously developed wound care app and graded the amount of wound drainage on a 5-point scale. Data about PJI in the follow-up period were extracted from the patient files. Results: Of the 1019included patients, 16patients (1.6 %) developed a PJI. Minor wound drainage decreased from the first to the fourth postoperative week from 50 % to 3 %. Both moderate to severe wound drainage in the third week and newly developed wound drainage in the second week after a week without drainage were strongly associated with PJI (odds ratio (OR) 103.23, 95 % confidence interval (CI) 26.08 to 408.57, OR 80.71, 95 % CI 9.12 to 714.52, respectively). The positive predictive value (PPV) for PJI was 83 % for moderate to heavy wound drainage in the third week. Conclusion: Moderate to heavy wound drainage and persistent wound drainage were strongly associated with PJI. The PPV of wound drainage for PJI was high for moderate to heavy drainage in the third week but was low for drainage in the first week. Therefore, additional parameters are needed to guide the decision to reoperate on patients for suspected acute PJI.
