Garre's osteomyelitis of the mandible managed by nonsurgical re-endodontic treatment.

Chronic osteomyelitis with proliferative periostitis, known as Garre's osteomyelitis, is a type of osteomyelitis characterized by a distinctive gross thickening of the periosteum of bones. Peripheral reactive bone formation can be caused by mild irritation or infection. Garre's osteomyelitis is usually diagnosed in children and young adults, and the mandible is more affected than the maxilla. The following is a case report of a 12-year-old female patient with Garre's osteomyelitis of the mandible due to an infection of a root canal-treated tooth. Without surgical intervention, the patient's symptoms were relieved through nonsurgical root canal re-treatment with long-term calcium hydroxide placement. A cone-beam computed tomography image obtained 6 months after treatment completion displayed complete healing of the periapical lesion and resolution of the peripheral reactive buccal bone. Due to the clinical features of Garre's osteomyelitis, which is characterized by thickening of the periosteum, it can be mistaken for other diseases such as fibrous dysplasia. It is important to correctly diagnose Garre's osteomyelitis based on its distinctive clinical features to avoid unnecessary surgical intervention, and it can lead to minimally invasive treatment options.

Associations of cumulative voriconazole dose, treatment duration, and alkaline phosphatase with voriconazole-induced periostitis.

OBJECTIVE: To investigate the associations of cumulative voriconazole dose, treatment duration, and alkaline phosphatase with voriconazole-induced periostitis. MATERIALS AND METHODS: One hundred and thirty-one patients with voriconazole use were identified using a clinical informatics tool. Health record data including age, sex, immune status, alkaline phosphatase, voriconazole levels, voriconazole dose, frequency, and treatment duration were collected. Imaging studies during the duration of treatment were reviewed by two radiology trainees and imaging features of voriconazole-induced periostitis were confirmed by a board-certified musculoskeletal radiologist. The length, location in the body, location in the bone, type, and morphology of periostitis lesions were recorded. Incident voriconazole-induced periostitis was defined as new periostitis on imaging after 28 days or more of voriconazole treatment in the absence of an alternative diagnosis. Univariate Firth's logistic regression models were performed using cumulative voriconazole dose, treatment duration, and average ALP as predictors and incident VIP as the outcome. RESULTS: There were nine patients with voriconazole-induced periostitis and 122 patients without voriconazole-induced periostitis. The most common lesion location in the body was the ribs (37%) and morphology was solid (44%). A 31.5-g increase in cumulative voriconazole dose was associated with 8% higher odds of incident periostitis. Increased treatment duration (63 days) and higher average alkaline phosphatase (50 IU/L) were associated with 7% higher odds of periostitis and 34% higher odds of periostitis, respectively. CONCLUSION: Increased cumulative voriconazole dose, treatment duration, and average alkaline phosphatase were associated with higher odds of voriconazole-induced periostitis.

Low-field magnetic resonance imaging of sagittal groove disease of the proximal phalanx in non-racing sport horses.

BACKGROUND: Injuries of the sagittal groove of the proximal phalanx (P1) in equine athletes are considered to predominantly occur due to chronic bone stress overload. OBJECTIVES: To describe the range of abnormalities that is present in the sagittal groove in a large group of horses diagnosed with sagittal groove disease (SGD) on low-field MRI. STUDY DESIGN: Retrospective, cross-sectional. METHODS: Medical records were searched to identify initial MRI images of horses diagnosed with SGD and these were blindly evaluated using a semi-quantitative grading scheme and novel SGD MRI classification system reflecting potential pathways of pathological progression and severity of stress injury. RESULTS: A total of 132 limbs from 111 horses were included in the study; predominantly warmbloods competing in showjumping (n = 83) and dressage (n = 18). SGD MRI classifications were: 0 (normal, n = 0), 1 (small subchondral defect, n = 2), 2 (osseous densification, n = 28), 3 (subchondral microfissure with osseous densification, n = 7), 4 (bone oedema-like signal within the subchondral ± trabecular bone and ± subchondral microfissure or demineralisation, n = 72), 5 (incomplete macrofissure/fracture, n = 23) and 6 (complete fracture, n = 0). Classification 4c (bone oedema-like signal with demineralisation) and 5 had higher proportions in the plantar third of hindlimbs (3% and 10%, respectively) compared with forelimbs (0% and 0%, respectively). SGD classification and extent of bone oedema-like signal were not significantly different between lame (n = 116) and non-lame limbs (n = 16) (both p > 0.05). Periosteal new bone and oedema-like signal were identified (either confidently or suspected) at the dorsoproximal aspect of P1 in 25% and 39% of limbs, respectively. MAIN LIMITATIONS: Inclusion via diagnoses in original MRI reports, variable clinical history, small size of some classification groups. CONCLUSIONS: The presence or absence of lameness is not a dependable measure of the severity of SGD. The periosteal oedema-like signal of P1 has not previously been described in MRI of SGD and further supports the concept of bone stress injury.

A Rare Case of Garre's Osteomyelitis of Tibia in an Adult.

To explore a rare case of Garre's osteomyelitis in an adult, typically observed in children, and detail its diagnostic and treatment approach, we conducted a case study of a 40-year-old male presenting with persistent right tibial pain. Through diagnostic procedures, including radiography and MRI, a broad differential diagnosis was established. Histopathological examination post-surgical intervention confirmed Garre's osteomyelitis. The treatment, which included corticotomy debridement, saucerization, ceramic granules insertion, and targeted antibiotic therapy, resulted in significant improvement over one year. This case underscores the importance of considering Garre's osteomyelitis in the differential diagnoses of chronic tibial lesions in adults and highlights the necessity of a comprehensive diagnostic and treatment approach in managing such rare cases, thus contributing valuable insights to orthopedic practice and literature.

Influenza vaccine related periostitis: A case report of a rare complication.

As social distancing guidelines continue to diminish across the country, viral pathogens that were once absent during the COVID-19 pandemic, such as influenza and RSV, have once again become prominent. Although serious side effects of vaccinations are rare, local complications of bursitis and skin and soft tissue infections are well-documented in the literature. We present a case of 1 such rare side effect: influenza vaccine related periostitis. A 39-year-old male patient presented with left shoulder pain which developed 2 days after an influenza vaccination administered to the left deltoid. His symptoms were persistent despite rest and 1 week trial of NSAIDs. MRI imaging demonstrated marrow edema and a periosteal reaction of the left shoulder. Overall, vaccine induced periostitis is poorly documented in the literature and the pathophysiology has not been fully characterized. Further research is crucial to identify patient specific risk factors and to raise awareness of this rare complication to promote swift diagnosis and effective treatment.

Monostotic Scapular Caffey Disease: A Case Report With MRI Correlate.

Caffey disease, also referred to as infantile cortical hyperostosis, is a self-limiting inflammatory disease of bone, typically diagnosed in infancy (ages less than five months). This disease is characterized by asymmetric, often polyostotic bony hyperostosis and expansion, with a predilection for the mandible (70-90%). We present a unique case of a two-month-old boy with monostotic scapular hyperostosis. The disease is primarily diagnosed on plain film and further evaluated with bone scintigraphy or skeletal survey to identify the extent of osseous involvement. Accompanying MR imaging is not usually obtained due to lack of specificity and diagnostic utility, and when pursued, can potentially confound the diagnosis. MR findings of this case are presented to re-iterate the benignity of this disease process and obviate the need for further invasive procedures.

A Case of Osteopetrosis with Orbital Inflammation Secondary to Maxillary Osteomyelitis.

Introduction: Osteopetrosis is a rare heritable disorder characterized by increased bone density resulting from osteoclast dysfunction. Major complications include bone fracture, osteomyelitis, anemia, and cranial nerve compression. Optic atrophy can occur due to compression of the optic nerve. Although osteomyelitis of the jaw is a common complication, it rarely occurs in the maxilla. Here, we report a case of a 74-year-old female with osteopetrosis who developed maxillary osteomyelitis, leading to orbital inflammation. Case Presentation: She was referred to our clinic for 2 months of ptosis and swelling of the left eyelid and temporal region. Previous imaging revealed a left intraorbital occupying lesion, but a biopsy of the temporal subcutaneous tissue did not provide a definitive diagnosis. After 7 months, she presented with severe temporal swelling and purulent discharge. Upon examination, maxillary osteomyelitis resulting from caries of the upper jaw was observed. Treatment with oral antibiotics, drainage of the temporal skin fistula, and regular cleaning of the maxillary drainage improved her symptoms. Conclusion: This is a rare case of maxillary osteomyelitis associated with osteopetrosis, causing orbital inflammation.

Sciatic neurotmesis and periostitis ossificans progressiva due to a traumatic/unexpected glass injury: a case report.

Peripheral nerves may be affected or injured for several reasons. Peripheral nerve damage can result from trauma, surgery, anatomical abnormalities, entrapment, systemic diseases, or iatrogenic injuries. Trauma and iatrogenic injuries are the most common causes. The ulnar, median, and radial nerves are the most injured nerves in the upper extremities, while the sciatic and peroneal nerves are the most injured nerves in the lower extremities. The clinical symptoms of peripheral nerve damage include pain, weakness, numbness/tingling, and paresthesia. Therefore, early diagnosis and appropriate treatment of peripheral nerve injuries are crucial. If a peripheral nerve injury is left untreated, it can lead to severe complications and significant morbidity. The sciatic nerve is one of the most affected nerves. This nerve is generally injured by trauma and iatrogenic causes. Children are more susceptible to trauma than adults. Therefore, sciatic nerve injuries are observed in pediatric patients. When the sciatic nerve is damaged, pain, weakness, sensory loss, and gait disturbances can occur. Therefore, the diagnosis and treatment of sciatic nerve injuries are important to avoid unexpected consequences. Ultrasound can play an important role in the diagnosis of peripheral nerve injury and the follow-up of patients. The aim of this case report is twofold. First, we aimed to emphasize the critical role of ultrasonographic evaluation in the diagnosis of peripheral nerve injuries and pathologies. Second, we aimed to present this case, which has distinguishing features, such as the existence of periostitis ossificans progressiva with sciatic neurotmesis due to a traumatic glass injury.

Fibro-Osseus Pseudotumor of the Digit: A Case Report and Review of Literature.

Introduction: Bony subungual growths arising on the digital tip are uncommon. Among these, subungual exostosis is a common cause. Case Presentation: We describe a 35-year-old-male patient with a rare occurrence of a fibro-osseus pseudotumor of the digit. It presents with reactive intramembranous ossification, with no continuity with the distal phalanx, helping differentiate it from a subungual exostosis. The patient presented with an asymptomatic subungual growth, lifting up the nail plate distally causing onycholysis. The characteristic clinical, radiological, and histopathological features of the case are described, which helped confirm the diagnosis. Conclusion: Cases with fibro-osseus pseudotumor of the digit reported in literature are reviewed comprehensively. The factors helping differentiate this from the other bony tumors affecting the distal phalanx, including subungual exostosis, myositis ossificans, and osteosarcoma are also highlighted.

Voriconazole-Induced Periostitis: A Case Report.

Voriconazole-induced periostitis (VIP) is an uncommon side effect typically seen in immunosuppressed patients requiring prolonged antifungal therapy. These patients can present with bone pain, fragility, and elevated alkaline phosphatase (ALP). We present a case of VIP in a 72-year-old immunocompromised female on antifungal therapy presenting with a comminuted intertrochanteric fracture after a ground-level fall. VIP, although rare, should be included as a differential diagnosis for patients presenting with bone pain and/or fractures with radiographic features of periostitis. This is particularly true when there is a history of or prior imaging suggesting a solid organ transplant. In these cases, a dedicated review of current medications noting long-term voriconazole use in the absence of underlying rheumatologic disease can result in a confident diagnosis.

Bizarre parosteal osteochondromatous proliferation: an educational review.

Bizarre parosteal osteochondromatous proliferation (BPOP) is a surface-based bone lesion belonging to the group of benign chondrogenic tumors. The aim of this review is to familiarize the readers with imaging features and differential diagnosis of BPOP, also addressing pathological presentation and treatment options. The peak of incidence of BPOP is in the third and fourth decades of life, although it can occur at any age. Hands are the most common location of BPOP (55%), followed by feet (15%) and long bones (25%). On imaging, BPOP appears as a well-marginated mass of heterotopic mineralization arising from the periosteal aspect of the bone. Typical features of BPOP are contiguity with the underlying bone and lack of cortico-medullary continuity, although cortical interruption and medullary involvement have been rarely reported. Histologically, BPOP is a benign bone surface lesion characterized by osteocartilaginous proliferation with disorganized admixture of cartilage with bizarre features, bone and spindle cells. Differential diagnosis includes both benign-such as florid reactive periostitis, osteochondroma, subungual exostosis, periosteal chondroma and myositis ossificans-and malignant lesions-such as periosteal chondrosarcoma and surface-based osteosarcoma. Treatment consists of surgical resection. Local recurrences are common and treated with re-excision.Critical relevance statement Bizarre parosteal osteochondromatous proliferation is a benign mineralized mass arising from the periosteal aspect of bone cortex. Multi-modality imaging characteristics, pathology features and differential diagnosis are here highlighted to familiarize the readers with this entity and offer optimal patient care.

Prevention of Dry Socket with Ozone Oil-Based Gel after Inferior Third Molar Extraction: A Double-Blind Split-Mouth Randomized Placebo-Controlled Clinical Trial.

Tooth extraction is followed by a sequence of elaborate local changes affecting hard and soft tissues. Dry socket (DS) can occur as intense pain around and in the extraction site, with an incidence from 1-4% after generic tooth extraction to 45% for mandibular third molars. Ozone therapy has gained attention in the medical field because of its success in the treatment of various diseases, its biocompatible properties and its fewer side effects or discomfort than drugs. To investigate the preventive effect of the sunflower oil-based ozone gel Ozosan® (Sanipan srl, Clivio (VA), Italy) on DS, a double-blind split-mouth randomized placebo-controlled clinical trial was conducted according to the CONSORT guidelines. Ozosan® or the placebo gel were put in the socket, and the gels were washed off 2 min later. In total, 200 patients were included in our study. The patient population comprised 87 Caucasian males and 113 Caucasian females. The mean age of the included patients was 33.1 ± 12.4 years. Ozosan reduced the incidence of DS after inferior third molar extraction from 21.5% of the control to 2% (p < 0.001). Concerning the dry socket epidemiology, the incidence was not significantly correlated with gender, smoking or mesioangular, vertical or distoangular Winter's classification. Post hoc power calculation showed a power of 99.8% for this data, with alpha = 0.001.

Recurrent osteomyelitis with proliferative periostitis after segmental resection and reconstruction of the mandible: a case report.

A 50-year-old patient presented with a two-year history of chronic osteomyelitis of the left mandibular body. It was treated by wide segmental resection of the left hemimandible and reconstruction with a free vascularized fibular graft. Six months after surgery, the patient returned with pain, swelling, and moth-like lesions in the transplant in combination with appositional bone formation surrounding the ossified fibular bone. Radiographic and histological examination led to the diagnosis of a recurrent osteomyelitis with proliferative periostitis affecting the resected and reconstructed mandible. Application of ibandronate led to a significant symptom decrease.

Hypertrophic Osteoarthropathy: A Case of an Undifferentiated Polyarthritis.

Hypertrophic osteoarthropathy is a paraneoplastic syndrome and is considered an important secondary cause of rheumatic disease. It typically manifests as tibial and femoral bone pain, with arthralgia or synovitis of adjacent joints also being common findings. Usually, musculoskeletal symptoms accompany the course of the disease, disappearing with treatment of the neoplasm and recurring coincidentally with the tumor relapse. The authors report a case of a patient with hypertrophic osteoarthropathy, whose etiological study allowed the diagnosis of a lung adenocarcinoma, particularly challenging due to the patient's young age and the absence of associated symptoms.

Voriconazole-Induced Diffuse Periostitis.

Background/Objective: Voriconazole treatment has been associated with diffuse periostitis, especially in immunocompromised patients who have had transplants or are on immunosuppressants. Here, we present a case of diffuse periostitis induced by prophylactic low-dose voriconazole for pulmonary aspergillosis. Case Report: A 66-year-old woman presented with 1 year of progressive, diffuse bone pain most prominent over the left shoulder and bilateral hips. She had a history of sarcoidosis requiring a single orthotopic lung transplant. Left phalangeal soft tissue swelling and painful nodules without clubbing were noted on examination. Prophylactic voriconazole 200 mg twice a day for pulmonary aspergillosis was prescribed for over 7 years. Elevated levels of alkaline phosphatase (469 units/L [reference range, 38-126]), bone-specific alkaline phosphatase (125 µg/L [0-20]), and parathyroid hormone (137 pg/mL [8-54]) and normal c-telopeptide level (842 pg/mL [34-1037]) were noted. Radiographs showed "multifocal periostitis" in both hip joints and bilateral proximal femurs, findings suggestive of voriconazole-induced periostitis deformans. Voriconazole was discontinued, and the patient improved symptomatically, despite persistent bone deformities on imaging. Discussion: Diffuse bone pain can be due to various pathologies, including metabolic or inflammatory diseases and bone tumors. Voriconazole-induced periostitis is caused by skeletal fluorosis, which can result in diffuse bone pain. It is a clinical diagnosis that is supported with radiologic findings, including focal, nodular, dense, and irregular periosteal reactions. Biochemical evaluation may reveal elevated alkaline phosphatase levels, but it is usually related to normal voriconazole trough levels. Periostitis is a benign condition, and discontinuation of the drug usually leads to clinical improvement. Conclusion: Voriconazole-induced periostitis should be considered as a diagnosis in elderly, immunosuppressed patients with diffuse bone pain on antifungal treatment. Early recognition of voriconazole-induced periostitis may result in both improved patient clinical outcomes and avoidance of unnecessary diagnostic testing.

Florid Reactive Periostitis of the Clavicle: A Case Report.

Florid reactive periostitis (FRP) is a rare benign fibro-osseous proliferation, occurring mostly in the short tubular bones of hands and rarely in the long tubular bones. We report a surgically confirmed case of FRP involving the clavicle in a 26-year-old male. On MRI scans, a soft tissue mass with T2 high signal intensity was found that originated from the periosteum of the clavicle and included surrounding a periosteal elevation and perilesional soft tissue edema. Strong contrast enhancement was noted inside the mass and along the periosteum involving more than half of the circumference of the clavicle. Serial radiographs revealed a soft tissue mass without mineralization that turned into an ossified mass with a solid periosteal reaction within a month.

Sclerosing Osteomyelitis of Garré: A Clinico-Radiological Correlation.

Sclerosing osteomyelitis of Garré is a rare and very specific type of chronic osteomyelitis that mainly affects children and young adults. To date, there is no clear etiology for the disease. Clinical findings and laboratory results are usually unremarkable with commonly negative blood and tissue cultures. Cortical thickening and periosteal reaction are common radiological findings. Biopsy often shows chronic non-specific inflammatory changes. It is a well-described entity in the dental literature, but to the best of our knowledge, there are no distinctive diagnostic criteria for long bones. We report a case of sclerosing osteomyelitis of Garré in a young lady involving the right tibia, for which the diagnosis was made based on clinico-radiological correlation.

[Bilateral periostitis and arthritis: about a case of hypertrophic osteoarthropathy]. / Périostite bilatérale et polyarthrite : à propos d'un cas d'ostéoarthropathie hypertrophique pneumique.

We report the case of a 67-year-old female patient presenting swelling of the hands and feet and pain in both legs. Clinical examination and bone scintigraphy identify the triad "digital clubbing - arthritis - bilateral periostitis of the long bones", leading to a diagnosis of hypertrophic osteoarthropathy, a syndrome usually associated with pulmonary neoplasia. The thoracic CT-scan, followed by a biopsy, effectively diagnosed a right upper lobe adenocarcinoma. Surgical treatment of the neoplasia allowed the resolution of the clinical complaints and the pathological scintigraphic findings.

Nous rapportons le cas d'une patiente de 67 ans présentant des gonflements des mains et des pieds ainsi que des douleurs des deux jambes. L'examen clinique et la scintigraphie osseuse identifient la triade «hippocratisme digital - arthrites - périostite bilatérale des os longs¼, permettant de poser un diagnostic d'ostéoarthropathie hypertrophique, un syndrome habituellement associé à une néoplasie pulmonaire. Le scanner thoracique, suivi d'une biopsie, ont en effet diagnostiqué un adénocarcinome localisé au niveau du lobe supérieur droit. La prise en charge chirurgicale de la néoplasie a permis la résolution des plaintes cliniques et de l'aspect scintigraphique pathologique.

Enlarged Reactional Periostitis of the Peroneal Tubercle Mimicking Osteochondromatosis of the Calcaneus: A Case Report.

Foot and ankle tumors are relatively rare. Nevertheless, the calcaneus is a prevalent location accommodating various lesions. Reactional periostitis of the lateral wall is rarely encountered but can potentially mimic a wide variety of tumors. We present a case of excessive proliferation due to chronic compression of the peroneal tendons against the calcaneus in a female patient with a history of diminished foot control, treated successfully by tumor excision and peroneal restoration via the tubularization technique. This study aimed to underline the mimicking potential of reactional periostitis and its effect on the peroneal tendons and hindfoot motion.

Simultaneous ocular and osseous syphilis: a case report / Sífilis com envolvimentos ocular e ósseo simultâneos: um relato de caso

ABSTRACT Syphilis is a reemerging and potentially serious disease. Owing to its ubiquity and pleomorphism, it is called "the great imitator". We report the case of a young woman with secondary syphilis who presented with bilateral acute syphilitic posterior placoid chorioretinopathy along with a syphilitic skull periostitis. A pachymeningeal enhancement was observed on magnetic resonance imaging, but we believe it was an extension of the bone process rather than a meningitis itself on the basis of the normal cerebrospinal fluid analysis results. Treatment with intravenous crystalline penicillin resulted in complete resolution of the signs, symptoms, and imaging findings. Secondary syphilis is the stage with the highest bacteremia and the highest transmissibility, presenting mainly with mucocutaneous disorders and, less frequently, with involvement of other organs. High suspicion and a pragmatic approach are essential to the diagnosis because this disease can affect several organs, as in the present case, in which the eyes, bones, and skin were affected.

RESUMO A sífilis é uma doença reemergente e potencialmente grave. Por sua onipresença e pleomorfismo, é denominada "grande imitadora". Relatamos caso de paciente jovem com sífilis secundária, que se apresentou com coriorretinopatia placóide sifilítica posterior aguda bilateral, simultaneamente a periostite craniana sifilítica. A despeito de realce paquimeníngeo observado na ressonância magnética, acreditamos que este tenha sido uma extensão do processo ósseo e não, uma meningite em si, uma vez que o exame do líquido cefalorraquidiano estava completamente normal. Tratamento com penicilina cristalina intravenosa resultou em completa resolução dos sinais, sintomas e achados de imagem. A sífilis secundária é o estágio de maior bacteremia e maior transmissibilidade da doença, apresentando-se principalmente com quadros mucocutâneos, mas também, menos frequentemente, com envolvimento de outros órgãos. Elevada suspeição e uma abordagem pragmática são necessárias para o diagnóstico, uma vez que essa doença pode afetar vários órgãos, como no caso relatado, em que foram acometidos olhos, ossos e pele.
