Just Keep Swimming...Just Keep Swimming

History: We present a 15-year-old right hand dominant high school swimmer with no significant past medical history, who complains of right elbow pain along the distal biceps' tendon for a 2 months. Pain was insidious in onset, sharp, intermittent, and described as a 0 to 6 out of 10. The patient has been swimming more frequently over the last few months to prepare for competition and noticed progressive pain with swimming. He went on vacation and then was diagnosed with a COVID-19 infection and took an additional 2 weeks off due to fatigue. He returned to sport without re-integration and increased his swimming intensity to 1 to 2 hours daily, which worsened his pain. Performing the butterfly and breaststroke provoke symptoms and cessation of activity reduces the pain. Denies pain at rest. He took Advil which did not reduce his pain. Denies acute trauma, prior injuries, or paresthesias. Physical Exam: Inspection of right elbow: no swelling or signs of discoloration. Palpation: Tenderness at the distal biceps tendon but can hook the tendon without pain. No shoulder or wrist tenderness. Active Range of Motion: Elbow extension 0 degrees, elbow flexion 130 degrees, supination and pronation normal. Normal shoulder and wrist ROM. Muscle strength: 5/5 grip, wrist extension, and wrist flexion. Pain elicited with resisted elbow flexion at the distal humerus. Maneuvers: pain with distal humerus squeeze. Negative Maudsley and negative Cozen test. Differential Diagnosis: 36. Distal Biceps Tendonitis/Tear 37. Stress Reaction of the Distal Humerus 38. Medial Epicondyle Apophysitis 39. Capitellar Osteochondritis Dissecans 40. Radiocapitellar Plica Syndrome Test Results: x-ray right elbow: AP and Lateral views indicate no abnormalities to the bones, alignment, or soft tissue structures. MRI right elbow No IVCON: Biceps tendon intact. There is periosteal edema and endosteal aspect marrow edema along the medial aspect of the distal diaphysis and metaphysis of the humerus. Several small foci of increased cortical signal. No fractures, joint effusion, or chondral defects. Findings comparable to Fredrickson grade 4a distal humerus diametaphysis stress injury. Final Diagnosis: Right Elbow Supracondylar Grade 4a Stress Reaction. Discussion(s): Actives that involve repetitive motion are susceptible to overuse injuries. Cases of upper extremity stress reactions in swimmers have been documented along the inferior angle of the scapula, upper ribs, and olecranon. Stress reactions along the distal humerus in swimmers is not well documented. This pathology has been seen in baseball players, cricket bowlers, and tennis players. In swimming, the butterfly technique requires significant endurance and athletic strength. During a sprint, fast synchronized upper extremity revolutions occurring up to 60 cycles perminute counterforcewater surface area friction leading to excessive loading forces even at 50 meter distances. Outcome(s): The patient was withheld from upper body work outs and swimming for 6 weeks. VitaminDand Calcium levels were drawn revealing a normal calcium level (10.2), but a vitamin D level of 28.1. Patient was started on 600 IU of Vitamin D and 1300 mg of Calcium daily. The patient started a return to swim program and returned to full competition at 7 months post presentation. Follow-Up: At 6 weeks, started an upper extremity low impact non-aquatic physical therapy program. Then a slow progressive return to swimming was initiated at 50% effort for 4 weeks. At 10 weeks, a return to sport plan including 200 m all strokes except butterfly, progressed to 250 m at week 2, 300 m at week 3, and 350 m at week 4. Finally, initiated speed work in =0 to 100 m increments and elbow loading workouts.

Chronic Chilblain Like Lesions Associated with the Covid-19 Pandemic

Background/Aims We report the features of chronic chilblain-like digital lesions newly presenting since the start of the covid-19 pandemic. Comparison with primary perniosis and acrocyanosis, reveals a unique phenotype which appears to be a long-covid phenomenon. Methods The case records of 26 patients with new onset persistent chilblain-like lesions presenting to the Rheumatology service of St George's University Hospital, London between Autumn 2020 and Spring 2022 were reviewed. Demographic and clinical features, serology, imaging, treatment response and outcome up to Summer 2022 were collated retrospectively. Results Chilblain-like lesions first occurred between September and March;2019/ 2020 6 cases, 2020/2021 18 cases and 2021/2022 2 cases. Mean age 35.4 (17-60) years, 88% female, 85% white, all non-smokers. Median body mass index (BMI) 20.2, range 17.0 - 33.2. BMI underweight (<18.5) in 27%. All cases reported new red-purple-blue colour changes of the fingers, some with pain, swelling and pruritis, affecting both hands in 12, one hand in 6, and both hands and feet in 8 cases. There was a past history of cold sensitivity or primary Raynaud's in 54%. Covid was confirmed in 3 cases, 2 - 8 months prior to onset of chilblain-like symptoms. Possible covid, unconfirmed, was suspected in 5 cases, 1 - 11 months earlier. Affected digits appeared diffusely erythro-cyanotic in 81%, with blotchy discrete maculo-papular erythematous lesions in 42%, some with both features. Involvement was asymmetric in 54%, thumbs spared in 69%. Complement was low in 50% (8/16), ANA positive in 26% (6/23). MRI of hands showed phalangeal bone marrow oedema in keeping with osteitis in 4 of 7 cases. More severe signs and symptoms were associated with low BMI, low C3/4 and a past history of cold sensitivity or Raynauds. Cold avoidance strategies were sufficient for 58%. Pain prompted a trial of NSAIDs, aspirin, nitrates, calcium channel blockers, hydroxychloroquine, oral or topical corticosteroid or topical tacrolimus in 42%. In general, these were minimally effective or not tolerated. 4 severe cases received sildenafil or tadalafil, effective in 2. In 27% complete remission occurred during the first summer season after symptoms commenced, median duration 6 (range 2 - 10) months. In the remaining 19 cases, chilblain-like symptoms returned or worsened in the subsequent second winter period, with 6 of 19 entering remission the following summer. For the remaining 13 persistent cases the total duration of symptoms spans more than a year, and in four cases more than 2 years. Conclusion This series illustrates a distinct chronic chilblain-like condition. Features similar to primary perniosis include female predominance, middle age, pruritic painful blotchy lesions, asymmetry and low BMI. Features in keeping with acrocyanosis include chronicity, extensive diffuse erythro-cyanotic discoloration, relative improvement in warm weather and lack of association with smoking.

Is Primary Bone Marrow Edema of the Knee Associated with Thyroid Disorders? A Retrospective Clinical Study.

Primary bone marrow edema (BME) of the knee is still an elusive condition. This retrospective study was undertaken to gain insight into its characteristic features. The records of 48 patients with primary BME of the knee diagnosed by magnetic resonance imaging were reviewed. Demographic data, medical history, current medications, pain type, smoking and drinking habits, allergies, occupation, sports practiced, environmental factors, and life events predating symptom onset were examined. Data analysis demonstrated that 56.3% of patients had experienced a stressful event before BME pain onset and that 50% suffered from thyroid disorders. Standard conservative treatment resulted in pain resolution irrespective of the use of anti-inflammatories. However, most patients reported new persistent symptoms: dysesthesia/hypoesthesia on palpation in the skin area overlying the previous edema and a reduced ipsilateral patellar reflex. To our knowledge, this is the first study characterizing a substantial cohort of patients with BME. We found that middle-aged, sedentary, and slightly overweight women smokers are the typical patients with primary BME of the knee. The appearance and persistence of cutaneous dysesthesia/hypoesthesia at the site of the earlier lesion and ipsilateral patellar hyporeflexia implicate an autonomous nervous system dysfunction in BME pathogenesis and warrant further investigation.

All in the Marrow - a Case of Primary Bone Marrow Oedema

Introduction/Background: Primary bone marrow oedema syndrome is an elusive and less well-defined entity. Whether Rheumatologists should consider it as a stand alone diagnosis, is debatable. It possibly would be best described as an MRI feature which could be a finding in a number of diseases which would include the initial phases of Osteonecrosis of the bone, Rheumatoid Arthritis, Spondyloarthritis, Enthesitis related, Post traumatic, OA, Infections and Cancers. The treatment options become constricted due to the paucity of evidence. Rheumatologists need to consider this as an area of unmet need with development of consensus classification criteria and treatment approaches. Description/Method: 27-year-old male, Height 174 cms Weight 90 Kgs BMI 29 Kg/m2, became symptomatic in Jan 2022 with complains of pain in the both hip joints & groin regions, pain became excruciating and he became bed-bound, with early morning stiffness lasting approximately 45 mins. Had received steroids for COVID infection in August 2020. Investigations Hb 13.5gm/dl TLC 7000/mm3 Platelet 400 x 103/mm3 Sr Bil 0.8mg/dl AST 16 IU/L. ALT 24 IU/L Sr Creatininine 1.1mg/dl Blood Sugar Levels, Fasting 89 mg/dl Post Prandial 102 mg/dl ESR 10mm in 1st hour by Wintrobes method CRP Quantitative 29.38mg/L HLA B27 by PCR Negative, RF Negative, ACCP Negative Serum, IgG, Beta2 Glycoprotein 1.44 SGU Serum, IgM, Beta2 Glycoprotein 3.44 SGU Serum, IgG, Cardiolipin antibody 8.4 GPL Serum, IgG, Cardiolipin antibody 17.45 GPL Lupus anticoagulant by DRVVT Negative Sr Cholesterol 211mg/dl HDL 29 mg/dl LDL 156mg/dl TGs 130 mg/dl MRI Hips & SI joints Transient bone marrow oedema/osteopenia of bilateral hip. PET CT Increased metabolic activity in both hip joints Bone Scan (99mTcMDP) Increased vascularity in perfusion phase, increased accumulation in soft tissue in blood pool phase and increased uptake in bilateral Hip joints in skeletal phase scan, suggestive of CRPS Type-I. Management Was initially managed with Tab Etoricoxib 90mg BD, also started on Tab Sulphaslazine and Tab Methotrexate. However, when he had no symptomatic relief he was administered Inj Infliximab on 12 May 2022 and a second dose on 9 June 2022. He had excellent pain relief after the 1st dose, however after 10 days of the administration, he again began experiencing pain especially after walking. He also had pain in the knees on this occasion. He was also administered Inj Zoledronic 4mg on 23 May 2022. He is at present not requiring any NSAIDs over the last 1 month. Discussion/Results: The patient having presented with excruciating and debilitating pain was worked up and evaluation revealed features of bone marrow oedema on MRI which was corroborated with bone scan and PET CT imaging. The acute phase reactant CRP was also significantly elevated. The patient also gave history of early morning stiffness lasting approximately 45 mins. Hence an underlying Inflammatory process such as Spondyloarthritis(Peripheral) with enthesitis was considered. The confounding factors were the pain which worsened on mobilization, HLA B27 negative status, Rheumatoid Factor and ACCP negative status and past history of having received IV Corticosteroids for COVID infection in August 2020. In view of the debilitating pain and aworking diagnosis of Spondyloarthritis, hewas started onNSAIDs alongwith rest, initially, followed by conventional synthetic disease modifying agents in Rheumatic disease followed by biologic synthetic diseasemodifying agent - Inj Infliximab. The thought process was to avoid prolonged NSAID use to prevent the associated side effects. However, since Avascular Necrosis of the Femoral head is a very likely possibility, the patient is planned to be kept under close follow up. Key learning points/Conclusion: Collaborative efforts between the Departments of Nuclear Medicine, Radiology, Orthopaedics and Rheumatology are crucial in the early detection and approach to cases of Bone Marrow oedema. Avascular necrosis of head of Femur is a far more common entity and must be kept in ind even when a diagnosis of Bone Marrow oedema syndrome is being entertained. Diagnosis of Bone Marrow oedema syndrome must be entertained only as a diagnosis of exclusion. Continued follow up and regular imaging must be pursued rigorously in patients diagnosed with Bone Marrow oedema syndromes. There is a requirement to document acute phase reactants such as CRP and ESR in patients diagnosed with Avascular necrosis of bone as this data could help us differentiate AVN from Primary Bone marrow oedema in the early stages.

Sarcoid-like immune reaction following COVID-19 infection presenting with COVID toes and dactylitis

A 21-year-old woman presented with a 5-month history of swollen, painful, purple discolouration of her toes and fingers, which began 6 weeks after COVID-19 infection. This was refractory to ibuprofen and clobetasol 0.05% w/w ointment. She reported no other associated symptoms. On examination she had erythematous mottling of the tips of the toes and nail folds of the right foot and sausage-shaped deformities of the left second and fourth toes, consistent with dactylitis. Her blood work-up for COVID toes revealed a raised serum angiotensin- converting enzyme (ACE) level (64 U L-1) with no other abnormalities. Her chest X-ray was unremarkable. Plain radiographs of the feet showed soft tissue swelling and lacelike bony appearances with discrete areas of lucency, particularly affecting the middle phalanx of the left second toe. This pattern has been described in sarcoid arthropathy. Magnetic resonance imaging of the left foot demonstrated features of inflammatory arthropathy, including subarticular bone marrow oedema, periarticular soft tissue oedema and flexor tendon tenosynovitis. The findings were consistent with COVID toes;however, some features of the dactylitis extended beyond the expected presentation of a vascular manifestation of COVID-19. She displayed overlap features seen in sarcoid-related pathologies, including raised ACE levels and a lace-like bony appearance. We believe this to be a sarcoid-like immune reaction to COVID-19 presenting with COVID toes and dactylitis. A sarcoid-like immune reaction to COVID-19 with granulomatous skin lesions rather than dactylitis has been reported. Viral infections are a documented trigger for sarcoid- like immune reactions. This case suggests that COVID-19 can trigger sarcoid-like immune reactions, albeit with a more discrete presentation.

PHALANGEAL MICROGEODIC SYNDROME: IS THIS VERY RARE CONDITION BECOMING MORE COMMON?

Background/Aims Phalangeal microgeodic syndrome (PMS) is a rare condition with only a handful of published case reports. Most of these cases are recognised in childhood, typically in Japan. It presents with pain and dusky discolouration in the digits, distinct from Raynaud's phenomenon in that the colour change is fixed and pain constant. Symptom onset is related to cold exposure with first presentation usually occurring in winter. Features on magnetic resonance imaging (MRI) are striking and characteristic, with a distinct pattern of bone marrow oedema. Methods We report five cases of MRI-proven PMS all identified in the last 12 months, with symptom onset during the winter. The patients were all female, aged between 25 and 79. One patient was already under the care of rheumatology with an established diagnosis of systemic lupus erythematosus (SLE), but the remainder were De novo referrals presenting specifically with pain and discolouration of the digits. One patient developed symptoms 2 days after receiving the first dose of Pfizer/ Biontech RNA vaccine against COVID-19. One patient had to self-isolate following a COVID-19 contact and developed symptoms shortly thereafter, although there was no proven infection in the affected individual. Results Four out of five cases were managed conservatively, with advice on maintaining core and peripheral temperature and skin integrity. Without any specific therapy, these four cases improved spontaneously to coincide with increasing seasonal temperatures. The fifth case with existing SLE was treated with intravenous pamidronate and subsequently with a calcium channel blocker, with some improvement in symptoms. Conclusion In these authors' experience, it would seem PMS is increasing in incidence. It is unclear if this relates to wider availability and image quality of MRI, clinician bias due to personal experience of more cases or a genuine increase. The winter 2020/21 was particularly cold with sub-zero conditions lasting well into May, which may have impacted on this flurry of new cases. We have identified one prior case report which describes PMS in a patient with existing connective tissue disease. Our patient with SLE appeared to have a more severe clinical presentation requiring additional medical therapy to control the symptoms compared with the four cases where PMS was a standalone condition. Dermatological manifestations of acute COVID-19 infection are well documented in children and include chilblain-like lesions and acrocyanosis. Any association between COVID-19 and PMS is purely hypothetical and would require more study to identify any true relationship.

Phalangeal microgeodic syndrome - a rare vascular acrosyndrome in childhood

Introduction: Phalangeal microgeodic syndrome (PMS) is a rare disease of unknown etiology, which affects fingers and/or toes of children. Objectives: N/A Methods: N/AResults: Case Presentation The authors describe the case of a 9-year-old girl, who presented to the Pediatric Rheumatology outpatient clinic in November 2020 with painful swelling and cyanosis of all fingers for 3 weeks which had not improved with oral ibuprofen. She had no history of previous COVID-19 and, besides mild IgA vasculitis in 2015, was otherwise healthy. On physical examination, painful spindle-shaped swelling with functional limitation and cyanosis of fingers, associated with chilblain-like lesions were observed. She was started on pentoxifylline 400 + 200 mg/day and, later, nifedipine 0.5 mg/kg/day, and advised to avoid exposure to cold. Five months later she had marked improvement of pain and swelling, maintaining mild cyanosis. Laboratory workup revealed normal complete blood count, normal erythrocyte sedimentation and C-reactive protein, normal biochemical liver and renal parameters. Immunology tests showed normal IgG, IgA and IgM, positive antinuclear antibodies 1/100 and negative antidsDNA, ANCA, ACPA, rheumatoid factor, anti-ENA, anticentromere and antiphospholipd antibodies. Hand radiographs showed multiple small, round radiolucent images at the edge of the metaphysis of several phalanges. Hand MRI showed bone marrow edema in middle and distal phalanges of all fingers, and distal part of proximal phalanges (more diffuse and prominent in the second and fifth, bilaterally);there were no relevant changes in joints or tendons. These findings are compatible with PMS. Conclusion: This is a rare disease that should be included in the differential diagnosis of patients presenting with vascular acrosyndromes complaints. It can be misinterpreted as an infectious or post-infectious (namely COVID-19-related), inflammatory, or even malignant condition. It usually has a benign course and resolves with conservative treatment. Pediatric rheumatologists should be aware of this entity, as a timely and precise diagnosis prevents further investigations and complications.

A case of Candida albicans septic sacroiliitis complicating severe COVID-19 infection

Case report-IntroductionBacterial and fungal infections are recognised complications of viral pneumonia, particularly in patients who are critically ill. We describe a case of fungal sacroiliitis complicating severe COVID-19 pneumonia following a prolonged intensive care unit (ICU) admission.Candida albicans sacroilitis is a rarely reported infection with few case reports in the literature. Candida osteoarticular infections can present as septic arthritis, with knee involvement in 75% of cases, or osteomyelitis. The latter presentation differs based on age-vertebral involvement (51%) is more common in adults while children are more likely to present with infection in the long bones, ribs, or sternum.Case report-Case descriptionA 48-year-old Afro-Caribbean gentleman with a history of hypertension and obesity was admitted to the ICU with clinical, laboratory and radiographic features of COVID-19 infection despite persistently negative swabs. Whilst in ICU he required mechanical ventilation. His stay was further complicated by multiple infections, pulmonary emboli, and the presence of a cavitating lesion in the left lung. Cultures from bronchoalveolar lavage and a central venous catheter line grew Serratia Mascense, candida glabrata and pseudomonas were isolated from his urine. He was treated with multiple antibiotics including meropenem, tazocin, ceftazidime and avibactam.After 61 days in the ICU he was transferred to the ward. He developed severe pain in his right hip which was worse on movement. This was followed by urinary incontinence and sensory deficit in the right L2/L3 dermatome. He underwent magnetic resonance imaging (MRI) of his spine and sacroiliac joints which showed right sided sacroiliitis and oedema around the iliopsoas muscle. He was started on vancomycin, later changed to ceftazidime avibactam and metronidazole. An echocardiogram did not show any vegetations. He underwent a biopsy of his sacroiliac joints which confirmed the presence of leucocytes, extended cultures yielded candida albicans in one out of two biopsy specimens.Considering ongoing pyrexia, pain and inflammatory markers, intravenous fluconazole was added to his antibiotic regimen which resulted in a marked improvement in mobility. After four weeks, ceftazidime, metronidazole and avibactam were stopped, and fluconazole was administered as oral tablets. 6 days later he became febrile and IV fluconazole was restarted.A repeat chest CT showed resolution of the cavity but ongoing changes suggestive of organising pneumonia. A repeat MRI of the sacroiliac joints revealed minor improvement. Intravenous Fluconazole was continued for a total of 8 weeks and was changed to tablets for complete a total of 12 weeks.Case report-DiscussionThis is a severe case of COVID-19 infection who despite 9 negative PCR tests, on day 53, had positive IgG for SARS-CoV-2 infection, confirming our clinical suspicion. Particularly in the ICU setting, individuals are approximately ten times more likely to have secondary bacterial/fungal infections with more frequent detection of multidrug-resistant Gram-negative pathogens.This case highlights several difficulties. Urine cultures had confirmed candida albicans, likely to be related to catheter related urinary tract infections, and a possible source for our patient but also a resistant pseudomonas aeruginosa species. Furthermore, cultures were positive for Serratia Mascense, candida glabrata. He had also already been treated with prolonged, broad spectrum antimicrobial treatment. Considering this, establishing the aetiology of the septic sacroiliitis was challenging. The rarity of candida sacroiliitis and presence of the organism in just one specimen made this more difficult. This led to the decision of a repeat sacroiliac biopsy to supply sufficient samples for further microbial analyses such as 16S, 18S and mycobacteria culture, all of which were negative.He became febrile after the discontinuation of antimicrobials and a switch to oral fluconazole therapy. He was extensively re-investigated and despite resolution of t e lung cavity, there were changes which could have been consistent with an organising pneumonia. At this point he was neutropenic, mildly eosinophilic, and therefore a drug reaction was also considered.Repeat MRI revealed resolving muscle inflammation and minimal change at the bone site, with erosions and possible reactive bone marrow oedema. Following discussion with microbiology the decision was made to persist with intravenous Fluconazole. He continued to improve, and his inflammatory markers normalised after 8 weeks of treatment. Prednisolone was started for COVID-19 related pneumonitis. Long-term antifungal treatment is advisable, and we aim to complete 12 weeks of treatment.Case report-Key learning points Patients with SARS-CoV-2 infection, particularly those requiring ICU admission were at risk of developing superinfections with multidrug-resistant Gram-negative bacteria or fungal infections.Candida albicans sacroiliitis is rare therefore early aspiration/biopsy is essential for the management.Longer treatment is needed in osteoarticular candida infections, even up to 6 or 12 months, therefor long-term close monitoring of this patients is essential.The utility and timing of reimaging patients following such infections is still unclearClose multidisciplinary and interdisciplinary team collaboration is essential in the management of this complex patients.

Method for Diagnosing the Bone Marrow Edema of Sacroiliac Joint in Patients with Axial Spondyloarthritis Using Magnetic Resonance Image Analysis Based on Deep Learning.

Axial spondyloarthritis (axSpA) is a chronic inflammatory disease of the sacroiliac joints. In this study, we develop a method for detecting bone marrow edema by magnetic resonance (MR) imaging of the sacroiliac joints and a deep-learning network. A total of 815 MR images of the sacroiliac joints were obtained from 60 patients diagnosed with axSpA and 19 healthy subjects. Gadolinium-enhanced fat-suppressed T1-weighted oblique coronal images were used for deep learning. Active sacroiliitis was defined as bone marrow edema, and the following processes were performed: setting the region of interest (ROI) and normalizing it to a size suitable for input to a deep-learning network, determining bone marrow edema using a convolutional-neural-network-based deep-learning network for individual MR images, and determining sacroiliac arthritis in subject examinations based on the classification results of individual MR images. About 70% of the patients and normal subjects were randomly selected for the training dataset, and the remaining 30% formed the test dataset. This process was repeated five times to calculate the average classification rate of the five-fold sets. The gradient-weighted class activation mapping method was used to validate the classification results. In the performance analysis of the ResNet18-based classification network for individual MR images, use of the ROI showed excellent detection performance of bone marrow edema with 93.55 ± 2.19% accuracy, 92.87 ± 1.27% recall, and 94.69 ± 3.03% precision. The overall performance was additionally improved using a median filter to reflect the context information. Finally, active sacroiliitis was diagnosed in individual subjects with 96.06 ± 2.83% accuracy, 100% recall, and 94.84 ± 3.73% precision. This is a pilot study to diagnose bone marrow edema by deep learning based on MR images, and the results suggest that MR analysis using deep learning can be a useful complementary means for clinicians to diagnose bone marrow edema.
