Association of Preoperative Subchondral Bone Marrow Oedema with Outcomes after Lateral Unicompartmental Knee Arthroplasty.

OBJECTIVE: To determine whether the presence of preoperative subchondral bone marrow oedema (SBME) is associated with inferior outcomes after lateral unicompartmental knee arthroplasty (LUKA). STUDY DESIGN: Descriptive study. Place and Duration of the Study: Department of Orthopaedic Surgery, Chongqing Orthopaedic Hospital of Traditional Chinese Medicine, Chongqing, China, from January 2019 to June 2022. METHODOLOGY: Data on patients treated with LUKA were obtained from the Medical Registry Database. Two groups were made based on the presence and absence of SBME on preoperative magnetic resonance imaging (MRI). The visual analogue scale (VAS), American Knee Society Scores (AKSS), and rate of patient satisfaction were compared between the two groups. RESULTS: A total of 20 patients treated with LUKA were reviewed. The SBME was present in 9 cases and absent in 11 cases. Patients with SBME had inferior scores at preoperative evaluation and at 1, 3, and 6 months postoperatively. However, there was no significant difference between the groups at the 12-month follow-up. Eight (88.9%) patients with SBME were satisfied with the LUKA surgery versus 9 (81.8%) patients without SBME, showing no significant differences between groups. CONCLUSION: Presence of preoperative SBME is associated with inferior functional outcomes after LUKA within six months of follow-up. KEY WORDS: Bone marrow, Oedema, Knee, Arthroplasty, Outcome, Patient satisfaction.

Maxillary sinus opacification after surgery in asymptomatic patients: Transient swelling of the sinus mucosa or graft dispersion into the maxillary sinus. A radiographic report of three cases after a follow-up period of at least 5 years.

Maxillary sinus grafting is a predictable regenerative technique to facilitate maxillary posterior implant placement when there is insufficient vertical bone height inferior to the maxillary sinuses to allow placement of implants of adequate dimensions. It enables an increase in vertical bone height, which makes implant placement easier. Maxillary sinus mucosal membrane perforation is one of the most common intraoperative complications during maxillary sinus grafting and may result in extrusion of graft material into the sinus. When this occurs, the mucociliary function of the maxillary sinus may expel the extruded graft material through its natural ostium, though graft particles may remain in the sinus or possibly occlude the natural ostium. After grafting, transient maxillary sinus mucosal oedema may occur. A postoperative CBCT scan may reveal varying degrees of sinus opacification, namely partial, subtotal or total. Although it is always possible to identify graft material, which may enter the sinus as a result of membrane perforation that might not even be visible to the implantologist during the surgical procedure, it is challenging to assess whether sinus opacification is due to mucosal thickening or mucus accumulation. The aim of the present case series was to offer a pragmatic approach to managing asymptomatic patients whose CBCT scans demonstrated partial, subtotal or total maxillary sinus opacification with bone graft particles that seemed to have been extruded into the sinus.

Undiagnosed Intra-articular Synovial Hemangioma: A Rare Cause of Knee Pain and Swelling.

INTRODUCTION: Synovial hemangioma is a benign soft-tissue tumor of vascular origin. Hemangioma only accounts for 1% of all bone lesions and is mostly an incidental finding among the primary skeleton tumors. A delay in diagnosis results in joint degeneration and osteoarthritic damage because of infiltrating tumor growth. CASE PRESENTATION: We presented a rare case of an intra-articular synovial hemangioma in a 13- year-old pediatric patient who was asymptomatic for 5 years. She attended orthopedics OPD at AIIMS, Mangalagiri. Surgical excision of the mass and partial synovectomy was done. Synovial hemangioma came out to be the diagnosis following a histologic study. CONCLUSION: As radiography has limited diagnostic ability, synovial hemangiomas are difficult and challenging to identify on an outpatient basis. Histological examination and magnetic resonance imaging are extremely helpful. To minimize the hemarthrosis risks, early complete excision can be used as the best treatment modality.

Anasarca as the first presentation of anti-synthetase syndrome.

A woman in her 70s presented with anasarca and exertional dyspnoea. Investigation showed severe hypoalbuminaemia with no urinary or gastrointestinal protein losses. CT thorax reported lung consolidations, and transbronchial lung biopsy demonstrated organising pneumonia. Autoimmune myositis serology was positive for anti-Jo-1, anti-Ro-52, and anti-PM/Scl-100 antibodies. She was diagnosed with anti-synthetase syndrome with organising pneumonia. She was treated with oral prednisolone and oral mycophenolate mofetil with a good clinical response.

Edema of the upper extremity on the unaffected side in unilateral breast cancer patients.

Breast cancer-related lymphedema (BCRL) occurs usually on the affected side, and its cause and pathophysiology are well known. However, the cause of edema of the upper extremity on the unaffected side is barely known. It is often considered to be chemotherapy-induced general edema, and clinical evaluation is rarely performed in these patients. This study aimed to present the clinical characteristics of unilateral breast cancer patients with edema of upper extremity on the unaffected side, and to emphasize the importance of early diagnosis and medical interventions. This study retrospectively analyzed the medical records of unilateral breast cancer patients complaining edema of upper extremity on the unaffected side, from January 2020 to May 2021. Lymphoscintigraphy was used to assist in confirming the diagnosis of lymphedema, and Doppler ultrasonography or 3D computed tomography angiography were performed to differentiate vascular problems. Fourteen patients were enrolled in the study. Seven, 3, and 4 patients had edema of both upper extremities, edema of the upper extremity on the unaffected side only, and edema of all extremities, respectively. None of the 4 patients with edema of all extremities showed abnormal findings on examination. In patients with edema in the upper extremity on the unaffected side alone, lymphatic flow dysfunction was seen in 2 patients, and deep vein thrombosis (DVT) was diagnosed in 1. In patients with edema of both upper extremities, lymphatic flow dysfunction was seen in 2 patients, and DVT was diagnosed in 3. One patient had DVT and accompanying lymphatic flow dysfunction. Lymphedema and DVT were diagnosed in a number of patients with edema of the upper extremity on the unaffected side, and lymphedema can occur without direct injury to the lymphatic flow system. Therefore, clinicians should not overlook the fact that diseases that require early diagnosis and treatment can occur in patients with edema of the unaffected upper extremity.

Large birth mark and unilateral swelling of the lower extremity in a young teenager.

We describe an early adolescent male who was diagnosed with vascular malformation associated with unilateral limb overgrowth based on the clinical findings of a persistent port-wine stain since birth and gradually progressing right lower limb oedema since early childhood. Clinicians should keep in mind to clinically evaluate such malformations in detail, as well as contemplate genetic testing in patients presenting with a large port-wine stain at birth, particularly if well demarcated and lateral in a lower extremity.

Penoscrotal Edema as a Rare Complication of Acute Pancreatitis: A Case Report.

Background and Objectives: Scrotal swelling or hydrocele is a rare complication of acute pancreatitis described in the literature. We present a case of penoscrotal swelling caused by the first attack of acute interstitial edematous alcohol-induced pancreatitis in a young male patient. Case report: A 22-year-old man was admitted to the emergency unit due to diarrhea and vomiting since morning which was followed by severe abdominal pain. Urgent abdominal multislice CT scan showed steatosis, pancreatic swelling and acute peripancreatic fluid collection (interstitial edematous pancreatitis). Also, scan showed fluid between small bowel loops and along the anterior renal fascia, while there was minimal amount of fluid in the Douglas space. There was no sign of penoscrotal swelling. On the second day of admission, the patient developed left scrotal swelling and mild pain without erythema. On the fourth day, a control CT scan showed progression to moderately severe pancreatitis (CT severity index 4). Dilated scrotal veins of the pampiniform venous plexus with an increased caliber of the testicular veins were present on both sides, from the scrotum to the level of the inguinal canal. Penoscrotal swelling was significantly reduced on discharge. Conclusions: Penoscrotal swelling is a rare complication or manifestation of acute inflammation of the pancreas. It is important to identify scrotal swelling caused by pancreatitis because in severe cases it can be related to possible infertility in the future.

Common Comorbidities in Patients with Remitting Seronegative and Symmetrical Synovitis with Pitting Edema (RS3PE).

OBJECTIVES: Remitting seronegative symmetrical synovitis with pitting edema (RS3PE) is considered a rare inflammatory rheumatologic disorder that is seen primarily in older adult men. Patients present with arthralgias of large joints accompanied by painful pitting edema of the hands and feet. Few studies have reported the prevalence of metabolic syndromes, including diabetes mellitus and hyperlipidemia in these patients. METHODS: This case series reviewed 25 patients who were diagnosed as having RS3PE in a private outpatient clinic. RESULTS: Nearly half of the patients (48%) had diabetes mellitus, predominantly type 2, and more than half of the patients (60%) had hyperlipidemia. CONCLUSIONS: We believe that future case studies on RS3PE should include an assessment of various comorbidities that can be seen in patients with this autoinflammatory disorder. The increased availability of musculoskeletal ultrasound provides a potential area of study to differentiate this disorder from other inflammatory arthritis and improve reaching the correct diagnosis.

Surgical Treatment of Medically Refractory Encapsulating Peritoneal Sclerosis in a Patient After Kidney Transplant.

Encapsulating peritoneal sclerosis is a rare but highly morbid disease process in patients with end-stage kidney disease on peritoneal dialysis. Surgical management has been described in patients with encapsulation of bowel causing obstruction. Here, we describe a case of surgical management in a patient following kidney transplant with medically refractory ascites and lower extremity edema.

Temporal Swelling Following Cochlear Implantation: Frequency, Treatment, and Outcomes.

OBJECTIVE: To investigate the frequency, treatment, and outcomes of postoperative delayed-onset swelling around cochlear implants. STUDY DESIGN: Retrospective, observational, nonrandomized group study. SETTING: Academic medical center. PATIENTS/INTERVENTIONS: Among 354 patients (516 ears) who underwent cochlear implantation (CI) at our hospital between May 2009 and October 2022, 329 (472 ears: 138 children [246 ears] and 191 adults [226 ears]) with a follow-up period of >3 months were included. MAIN OUTCOME MEASURES: Physical examination and computed tomography of the head were performed. RESULTS: In total, 5.5% (26/472 ears) had a history of delayed-onset swelling around the implant. This complication occurred in 9.8% (24/246 ears) of children and 0.9% (2/226 ears) of adults. The mean time to onset of swelling was 50 (range, 5.5-147) months following CI. In 60% (21/35) of the cases, the cause was unknown, whereas in 25.7% (9/35) and 11.5% (4/35) of cases, it was head trauma and acute inflammation, respectively. Conservative treatment (observation, antibiotics, and/or strong magnetic compression) was adapted in 91.4% (32/35) of cases. After conservative treatment, revision CI surgery was performed in one ear. Additionally, recurrent swelling was observed in 23.1% (6/26 ears) of swelling cases. CONCLUSIONS: The results suggest that delayed-onset swelling around implants occurs more frequently in children than in adults because of the higher incidence rates of head trauma and acute otitis media in children. In most cases, conservative treatment was adequate; however, careful follow-up is necessary. Our findings can serve as a reference for optimizing care and intervention options after CI.

Tolvaptan therapy for edema in patients with chronic kidney disease.

OBJECTIVE: Tolvaptan is a vasopressin V2 receptor antagonist that is commonly prescribed to alleviate edema associated with renal diseases. However, the clinical benefits of tolvaptan in chronic kidney disease (CKD) remain unclear. This study aimed to evaluate the effectiveness of tolvaptan in managing edema caused by CKD. MATERIALS AND METHODS: The efficacy and treatment regimen of tolvaptan were assessed in a cohort of 96 patients with renal edema and CKD. During the treatment, the patients' creatinine (CR), uric acid (UA), and estimated glomerular filtration rate (eGFR) were monitored as important indicators of kidney function. Coagulation-associated molecules including fibrinogen, D-dimer, and fibrin degradation products (FDPs) were measured. Electrolyte disorders and acute kidney injury were closely monitored. Tolvaptan was administered at a daily dose of 7.5 mg, and 30 mg of edoxaban was administered to manage deep vein thrombosis. RESULTS: During the course of tolvaptan therapy, the eGFR of the patients was not declined. Edema was eliminated in 82.18% of patients. Proteinuria was reduced in the patients (p < 0.05). There were no significant changes in serum sodium levels throughout treatment, and no significant difference was observed in blood volume between the end of treatment and baseline levels. Importantly, acute kidney injury did not occur, and renal edema and deep vein thrombosis were successfully treated. CONCLUSION: As long as a rational treatment regimen is followed, tolvaptan is a safe and effective diuretic for treating edema in CKD, even in the late stages of CKD without reducing residual renal function in the patients.

Conceptual Approach to Body Fluids and Edema, Education Determines Clinical Outcomes in Heart Failure.

In this brief communication, we reemphasize the importance of critical thinking in clinical practice using the example of edema. The common practice of thinking and inquiry by practicing clinicians has beneficial implications for healthcare by improving outcomes and patient care while alleviating the burden of misconceptions in practice. We provide an in-depth and interactive investigation of physiological concepts as a foundation for understanding body fluid dynamics. Finally, we offer a new classification of symptoms of heart failure. DOI: 10.52547/ijkd.8171.

Bone marrow edema of the knee: a narrative review.

Bone marrow edema (BME) is a frequent MRI finding in patients with knee pain. According to the etiology, BME of the knee can be classified into three main categories: ischemic, mechanic, and reactive. The diagnosis may be difficult, because of the specificity of symptoms and the poor radiographic findings. MRI is the gold standard, showing an area of altered signal of the bone with an high signal intensity on fat-suppressed, T2 weighted images, usually in combination with an intermediate or low signal intensity on T1 weighted images. Bone marrow edema tends to be self-limiting and, in most cases, resolves without any consequences in a varying amount of time. However, since it may evolve to complete joint destruction, early diagnosis and correct treatment are crucial to prevent the articular degeneration. Conservative therapy is the first step, with no weight-bearing for 3 to 6 weeks on the affected side, in combination with the administration of anti-inflammatory drugs or painkillers to manage symptoms. In non-responding forms and more advanced stages, minimally invasive preservative surgery can provide significant results, with subchondroplasty and core decompression being the two main procedures available. Knee arthroplasty, both total (TKA) or unicompartmental (UKA), is the only effective option when the degradation of cartilage is diffuse and in patients with subchondral bone collapse.
