Pediatric Lyme arthritis is described but not well-characterized in urban populations. Similarities in clinical features between Lyme and septic arthritis also results in some patients with Lyme arthritis undergoing surgical treatment. The aims of this study are to (1) characterize Lyme arthritis in an urban population and (2) determine what factors predispose patients with Lyme arthritis to undergoing surgery. We performed a retrospective review of children with Lyme arthritis at a single academic institution in New York City from 2016 to 2021. Inclusion criteria were age ≤18 years, involvement of a major joint, and positive Lyme serology. Patients treated with irrigation and debridement were compared to those treated non-surgically using Chi-squared tests with a significance of P  < 0.05. A total of 106 children with Lyme arthritis were included. Mean age was 9.5 years; 61.3% were male, and 71.7% were Caucasian. 46.2% lived in regions with an average household income >$100 000; 70.8% had private insurance. Ten patients (9.4%) underwent surgery for suspected septic arthritis. The operative group was more likely to have an elevated heart rate, white blood cell count, C-reactive protein level, erythrocyte sedimentation rate level and synovial cell count ( P  < 0.05). Patients were more likely to undergo surgery if they presented to the emergency department than to the clinic ( P  = 0.03). The average time for a Lyme test to result was 43.5 h, averaging 8.7 h after the surgical start time. Lyme arthritis occurs commonly in an urban pediatric population. Surgery is performed in ~10% of Lyme arthritis patients. More efficient diagnostic tests may reduce this rate., (Copyright © 2022 Wolters Kluwer Health, Inc. All rights reserved.)

Context: Lyme disease is the most common tick-borne illness in North America and Europe, and Lyme arthritis is a frequent late-stage manifestation in the United States. However, Lyme arthritis has rarely been reported as a postoperative complication., Evidence Acquisition: The PubMed database was queried through June 2018, and restricted to the English language, in search of relevant articles., Study Design: Clinical review., Level of Evidence: Level 3., Results: A total of 5 cases of Lyme arthritis as a postoperative complication have been reported in the literature., Conclusion: These cases highlight the importance for providers practicing in Lyme-endemic regions to keep such an infection in mind when evaluating postoperative joint pain and swelling. We propose herein an algorithm for the workup of potential postoperative Lyme arthritis., Strength of Recommendation Taxonomy (sort): C.

An 8-year-old boy presented to the emergency department with swelling and pain of his left knee and calf for approximately 1 week. His examination was significant for moderate knee effusion and swelling of the posterior calf with erythema and warmth of the affected areas. An ultrasound obtained at an outside hospital showed a large heterogeneous mass in the gastrocnemius, and a magnetic resonance imaging revealed a large, heterogeneous, rim-enhancing collection in the medial head of the left gastrocnemius muscle with surrounding myositis involving the gastrocnemius muscle. The child was taken to the operating room by the orthopedic team for drainage and irrigation of the knee effusion and of the collection in the gastrocnemius. The diagnosis of Lyme pseudothrombophlebitis was made through Lyme serology testing of aspirated fluid. He improved after this drainage but required a prolonged antibiotic course.

Most patients with untreated Lyme disease will experience joint symptoms. Owing to their resemblance in clinical presentation, Lyme arthritis and septic arthritis are often difficult to differentiate. However, their treatment is different. The elbow is rarely the first joint to present with symptoms. Therefore, Lyme disease is not commonly included in the differential diagnosis for children presenting with isolated elbow pain. The authors report 4 cases of monoarticular Lyme arthritis presenting in the elbow. There was an average delay of diagnosis of 4.75 days. Three cases were treated with oral antibiotics alone; 1 case was treated with unnecessary surgery due to uncertainty of the diagnosis and the delay in the laboratory performing the Lyme serology tests. The authors strongly recommend that Lyme serology be performed on an emergent basis to prevent unneeded surgery. [Orthopedics. 2018; 41(4):e511-e515.]., (Copyright 2018, SLACK Incorporated.)

Case: We describe a case of refractory Lyme arthritis in an adolescent patient with a concomitant medial meniscal tear. The patient underwent arthroscopic synovectomy and meniscal repair, and required additional surgery for subsequent decreased range of motion. We describe the presentation, the intraoperative findings, the course of recovery, and the literature regarding Lyme arthritis and meniscal tears., Conclusion: Refractory Lyme arthritis commonly is treated successfully with arthroscopic synovectomy. We describe a patient who presented with a concomitant medial meniscal tear; he underwent initial medial meniscal repair and a partial meniscectomy. He required additional surgery before full recovery was achieved.

Unlabelled: Lyme disease also called ,,the illness with a thousand faces" ("The Great Imitator") because it may mimic very well the symptoms and signs of other diseases, is an unusual medical encounter for the urologist. Every patient with Lyme disease has his own clinical feature, while the superposition over an unknown but easy to discover urological disease may lead to a misdiagnosis., Case Presentation: Male patient A. P. was an emergency transfer in our clinic with multiple system organ failure. The mirage of first imaging finding, bilateral obstructive ureteral calculi was obviated after the serological confirmation of Lyme disease suspected after the thorough history obtained from his family. The intensive care treatment, broad-spectrum antibiotics and hemodialysis sessions, together with external urinary drainage, lead to the improvement of the patient status, and subsequent proper urological treatment to urolithiasis cure., Conclusions: This case identifies several challenges faced by practitioners, challenges which involve the diagnosis and the treatment of Lyme disease associated with urolithiasis. Although Lyme disease remains a controversial clinical entity, its diagnosis is based on a history of possible exposure to ticks, the appearance of specific clinical symptoms, whether or not combined with serological tests.

Lyme disease is the most common tick-borne disease in the United States and Europe. Increased awareness of the clinical manifestations of the disease is needed to improve detection and treatment. In the acute and late stages, Lyme disease may be difficult to distinguish from other disease processes. The epidemiology and pathophysiology of Lyme disease are directly related to the Borrelia burgdorferi spirochete and its effects on the integumentary, neurologic, cardiac, and musculoskeletal systems. Lyme arthritis is a common clinical manifestation of Lyme disease and should be considered in the evaluation of patients with monoarticular or pauciarticular joint complaints in a geographic area in which Lyme disease is endemic. Management of Lyme arthritis involves eradication of the spirochete with antibiotics. Generally, the prognosis is excellent. Arthroscopic synovectomy is reserved for refractory cases that do not respond to antibiotics.

Purpose: First report of a patient with Borrelia-associated crystalline keratopathy with intracorneal evidence of Borrelia garinii by polymerase chain reaction (PCR) and electron microscopy (EM)., Methods: Report of a 67-year-old patient with medical history of recurrent iridocyclitis and arthritis presented with a bilateral, progressive, asymmetric crystalline keratopathy, which was particularly pronounced in the peripheral temporal superior cornea. After penetrating keratoplasty, crystalline keratopathy with stromal haziness recurred. Corneal regrafting was performed. The corneal specimen from the penetrating keratoplasty was examined by light and EM as well as by PCR., Results: In the explanted corneal graft, as well as retrospectively in the corneal specimen from the first keratoplasty, spirochetelike bodies and fragments were detected by light and EM. Borrelia burgdorferi sensu lato DNA was demonstrated by broad-range (16S rDNA) PCR. A more precise identification as Borrelia garinii serotype 5 was possible by analyses of the flaB and ospA gene sequences. Borrelia-specific serological tests showed borderline titers in immunofluorescence and weak reaction in immunoblot, respectively., Conclusions: This case illustrates that borreliae must be considered as a cause of crystalline keratopathy; Borrelia-specific serological tests can be false negative; explanted cornea specimens of etiologically unclear crystalline keratopathy should be analyzed by EM or PCR for detection of pathogens; and prolonged antibiotic treatment might be effective to prevent progression or recurrence of the disease.

Objective: To determine whether Borrelia burgdorferi DNA may be detected in synovial tissue from patients with Lyme arthritis who have persistent synovial inflammation after antibiotic treatment., Methods: Synovial specimens obtained at synovectomy from 26 patients with antibiotic treatment-resistant Lyme arthritis and from 10 control subjects were tested for B burgdorferi DNA using 3 primer-probe sets that target genes encoding outer surface proteins A or B or a flagellar protein (P41) of the spirochete., Results: The 26 patients with Lyme arthritis, who had received antibiotic therapy for a mean total duration of 8 weeks prior to synovectomy, and the 10 control subjects each had negative polymerase chain reaction (PCR) results in synovial samples. When the samples were spiked with approximately 1-10 B burgdorferi, all but 1 had positive PCR results, suggesting that spirochetal DNA could have been detected in most of the unspiked samples if it had been present., Conclusion: These results indicate that synovial inflammation may persist in some patients with Lyme arthritis after the apparent eradication of the spirochete from the joint with antibiotic therapy.

Background: Ocular manifestations of Lyme borreliose present with unusual forms of conjunctivitis, keratitis, optic nerve disease, uveitis, vitritis and rarely endophthalmitis., Case Report: A 57-year-old man working as logger in Sax-ony-Anhalt suffering from an endophthalmitis on his left eye was referred to us. The vision of his left eye was intact light perception and hand motions. The slit-lamp examination revealed severe inflammation of the anterior chamber with hypopyon, posterior synechiae, and opacity of the posterior lens capsule. Funduscopy showed no red reflex, no retinal details. In the local hospital serum analysis was performed and showed in Western-Blot IgM- and IgG-antibodies against Borrelia burgdorferi. Despite of intravenous application of ceftriaxon for 14 days panuveitis persisted, and endophthalmitis developed when antibiotic therapy was finished., Results: During pars plana vitrectomy a sharply delineated cystic lesion containing yellowish fluid was revealed, and creamy yellow fluid was aspirated. Microscopically in hematoxylineosin stained slides of the aspirate structures consistent with Borrelia burgdorferi were found. Postoperatively vision increased to 1/15. Despite of a second intravenous ceftriaxon treatment for 14 days we observed a retinal vasculitis in the follow up of 6 months., Conclusions: Despite intravenous ceftriaxon-therapy borrelia burgdorferi must have survived in the vitreous body. Further investigations are required with respect to the use of other antibiotics or immunosuppressives.

Lyme arthritis typically causes intermittent attacks of oligoarticular arthritis in a few large joints, especially the knee. A small percentage of patients may develop chronic arthritis, again affecting primarily the knee. The diagnosis is usually based on the presence of this characteristic clinical picture, exposure in an endemic area, and a positive IgG antibody response to B. burgdorferi determined by ELISA and Western blotting. In addition, spirochetal DNA can often be detected in joint fluid by PCR. Joint involvement in this infection can usually be treated successfully with a 1- or 2-month course of oral doxycycline or amoxicillin, but patients with certain genetic and immune markers may have persistent arthritis despite treatment with oral or intravenous antibiotics. If patients have persistent arthritis despite a second course of antibiotics and if the results of PCR testing are negative, the author treats such patients with anti-inflammatory agents or arthroscopic synovectomy.

A case of Lyme arthritis with advanced degenerative changes localized to the midcarpal joint was treated with a limited wrist arthrodesis with relief of pain and improved function. Chronic Lyme arthritis occurs as the third stage of Lyme disease. Serologic testing and a history of a characteristic rash may be helpful in the diagnosis. Radiographic and histopathologic findings are nonspecific, with both degenerative and inflammatory characteristics. Intravenous antibiotics provide an effective treatment of chronic Lyme arthritis.

Of 20 patients who underwent arthroscopic synovectomy for refractory chronic Lyme arthritis of the knee, 16 (80%) had resolution of joint inflammation during the first month after surgery or soon thereafter, and they have remained well during the 3-8-year followup period. Three of these 16 patients who were more disabled preoperatively, still had mild functional limitation at long-term followup. The remaining 4 patients (20%) had persistent or recurrent synovitis. We conclude that arthroscopic synovectomy is effective in treating chronic Lyme arthritis in patients in whom the disease does not respond to antibiotic therapy.

A 25-year-old Hispanic male presented to the emergency room with complaints of severe left upper quadrant pain. Physicians determined that the patient had an acute inflammatory process with a possible diagnosis of splenic abscess. A splenectomy was performed. Histologic examination of the tissue sections revealed extensive necrosis and inflammation, but no etiologic agent was discernible. Microbiologic cultures of the tissue had negative results. A Dieterle silver stain revealed an overwhelming number of spirochetal bacteria most closely resembling Borrelia spp. The patient's serum was tested for serologic evidence of antibody to Borrelia burgdorferi with the following results; by indirect fluorescent antibody 1:32; by enzyme-linked immunosorbent assay for IgM, 1:320; and Western blotting had positive results for the presence of B. burgdorferi outer-surface protein antibodies. This is the first human case report of an acute necrotizing splenitis resulting from B. burgdorferi.
