[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.

Periostitis Ossificans Arising in the Mandibular Bone of a Young Patient: Report of an Unusual Case and Review of the Literature.

Periostitis ossificans, also known as Garré osteomyelitis, is a specific type of chronic osteomyelitis that forms new bone under the periosteum resulting from a periosteal reaction to chronic inflammation or infections. It commonly affects the mandible secondary to odontogenic infection. The therapeutic approach involves eliminating the infectious cause and antibiotic administration. This report describes an unusual case of periostitis ossificans arising from the mandible of an 11-year-old boy. The cause of infection was correlated with a lower right unerupted third molar, which had no obvious connection with the oral cavity. The histologic diagnosis was chronic osteomyelitis with proliferative periostitis. The patient has been followed for 1 year, without any evidence of recurrence. Periostitis ossificans can be diagnostically problematic, and various conditions must be considered in the differential diagnosis.

Florid reactive periostitis of the long bone: A case series of seven patients.

BACKGROUND: Florid reactive periostitis (FRP) is a rare benign periosteal lesion, which mostly involves the tubular bones of the extremities. FRP of the long bone is especially rare. We here report a case series of long bone FRP and also discuss the differential diagnosis and clinical outcome of our series. PATIENTS AND METHODS: In total, four female and three male patients with long bone FRP and a mean age of 25.1 years were evaluated for this study, from which four upper extremity and three lower extremity FRP lesions were identified. Patients were classified according to the clinical, radiological and pathological manifestations of the lesion. RESULTS: Periosteal reaction and edema around the lesions were observed in all cases. Calcified mass, bone marrow edema and cortical erosion were observed in six out of seven patients. Moreover, two lesions with peripheral mineralization and zoning appearances were observed. Limb rest and anti-inflammatory therapy proved to be sufficient treatment in all cases. The lesions were spontaneously resolved in all cases, leaving a residual exostosis. CONCLUSION: Our report indicates that short bone and long bone FRP could reveal different characteristics in some aspects, including the choice of the therapeutic approach. In spite of the favorable clinical outcome of long bone FRP, its differentiation from more aggressive lesions, especially osteosarcoma and osteomyelitis, should still be taken into consideration. In addition, according to our evidence, the implication of the zonal pattern in differential diagnosis of FRP and myositis ossificans (MO) could be re-evaluated.

Sclerotic multiple myeloma with an unusual sunburst periosteal reaction occurring in the sternum.

Multiple myeloma is a disseminated neoplastic monoclonal gammopathy that usually affects the skull, clavicle, rib, pelvis, spinal column, and proximal portions of the humerus and femur. The initial manifestation of multiple myeloma in the sternum is rare. The classic radiological presentations of multiple myeloma are multiple "punched-out" areas of bone destruction, expansile lytic lesions, and generalized osteoporosis. Primary sclerotic presentation is rare and occurs in only 3 % of cases. A sclerotic multiple myeloma with a sunburst periosteal reaction occurring in the sternum has not been reported in the English literature. We report a case of sclerotic multiple myeloma of a 49-year-old woman. In the sternum, the lesion displayed extensive sclerosis mixed with mottled lytic areas with a sunburst periosteal reaction occurring in the periphery, which radiologically mimicked an osteosarcoma. Multiple focal areas of sclerosis were also found in the right clavicle, pelvis, multiple ribs, and vertebrae.

O papel do periósteo nos procedimentos ortopédicos como exemplo de sua capacidade reparatória / The role of the periosteum in orthopedic procedures: an example of its reparative ability

Na Ortopedia, o periósteo adquire relevância por estar associado à morfologia óssea, que pode ser modificada pelas demandas funcionais, contribuindo enormemente com o dinamismo oferecido pela remodelação, ou turnover, óssea. Estudar mais profundamente a capacidade adaptativa, reacional e reparatória do periósteo nos permite entender: 1) o comando dos osteócitos na determinação da morfologia óssea, inclusive durante o movimento dentário induzido; 2) a expansão rápida do palato e as mudanças ocorridas na forma da maxila; 3) o deslocamento mandibular por aparelhos ortopédicos funcionais; 4) a etiopatogenia da periostite ossificante, antigamente denominada de osteomielite de Garrè; 5) a “expansão” das corticais durante os crescimentos císticos e tumorais. Nesse trabalho, discorre-se sobre os eventos celulares e teciduais das reações periosteais e suas extrapolações clínicas.

Paranasal sinus infection causing orbital subperiosteal abscess: surgical management of this devastating entity.

BACKGROUND: Orbital infection is an uncommon devastating infection and is usually a complication of paranasal sinus infection. Without appropriate treatment, orbital infection may lead to serious complications, even death. Prompt treatment is mandatory to avoid visual loss or intracranial complications. The literature shows that initially, intravenous antibiotics should be administered, and after 48 h, if no improvement appears, the affected orbit and the sinuses must be surgically drained. The authors describe two cases of orbital cellulitis with a brief literature review. CASE REPORT: The authors describe two cases of orbital abscess caused by paranasal sinus infection. In case 1, the patient presented a decreased visual acuity associated with ophthalmoplegia of the right eye. In case 2, the patient presented a decreased visual acuity. Thus, administration of intravenous antibiotic combined with surgical drainage was performed. After surgical procedure, eye movements were normalized in case 1, and in both patients, the visual acuity returned to normal parameters. DISCUSSION: The authors recommend early surgical drainage with parenteral antibiotic administration and careful postoperative observations by monitoring the signs and symptoms of the orbital complaint.

Osteomielitis crónica con periostitis proliferativa / Chronic osteomyelitis with proliferative periostitis

La osteomielitis crónica con periostitis proliferativa es un tipo de alteración caracterizada por una reacción periosteal exacerbada causada por un estimulo de baja intensidad, generalmente una lesión cariosa con patología periapical asociada. Actúa principalmente en niños y adolescentes con predilección por la región basilar de mandíbula. Clínicamente, se manifiesta a través de un aumento de volumen doloroso intra o extraoral, de consistencia endurecida. Radiográficamente presenta laminas óseas neoformadas, paralelas entre si con superficie cortical, observándose el aspecto típico de "cascara de cebolla". El tratamiento incluye el retiro del factor etiológico con o sin antibioterapia y posterior restablecimiento de la simetría facial del paciente. Este trabajo presenta un caso de osteomielitis crónica con periostitis proliferativa en una paciente de sexo femenino de 11 años de edad, causada por una lesión cariosa en el primer molar inferior izquierdo, quien fue sometida a exodoncia del diente comprometido con posterior restablecimiento de la simetría facial.

Chronic osteomyelitis with proliferative periostitis is a kind of osteomyelitis that is characterized by a great periosteal reaction resulting of low grade stimulation, usually a caries lesion associated a periapical pathology. It affects especially children and young adults, with the mandible as the most common site, usually in the inferior aspect. Clinically presents as a painless hard swelling intra and/or extra-oral. Radiographic aspects include bone layers new formed, parallel to each other and to the underlying cortical surface, giving the characteristic appearance of "onion skin". Treatment includes elimination of the cause, with or without antibiotics, being restored the facial symmetry of patient. The present article is a clinical case report of chronic osteomyelitis with proliferative periostitis affecting a female 11 year old patient, caused by a caries lesion in the left permanent first molar, that was submissed to a exodontia and the facial symmetry of the patient was restored with management.

[Orbital and nasal complications secondary to inhaled cocaine abuse]. / Complicaciones nasales y orbitarias secundarias al abuso de cocaína inhalada.

The abuse of inhaled cocaine causes chemical sinus pathology by secondary midfacial destruction and necrosis. When midfacial necrosis is already established, other complications may occur related to the proximity of structures such as the orbit or optic nerve. We present the evolution of a young cocaine addict with midfacial destruction, who has had a subperiosteal abscess and optic neuritis over the course of the years. Differential diagnosis and management of these complications are also discussed.

Periostitis of the metatarsal caused by a date palm thorn in a child: a case report.

Date palm thorn injuries are common in Middle Eastern countries, where there are many date palm plantations. If detected, these injuries can be treated without subsequent complications. In children, however, the diagnosis can very easily be missed. An untreated embedded thorn may cause late complications, including periostitis or osteomyelitis. In this article, the author presents a case of date palm thorn-induced periostitis of the fourth metatarsal. The lesion was successfully treated in this 10-year-old male by curettage of the lesion and removal of the thorn embedded in the periosteum of the metatarsal. The presence of the date palm thorn was confirmed with ultrasound scan and computerized tomography.

MRI features of cortical desmoid in acute knee trauma.

[Observation of dirofilariosis in the practical work of the otorhinolaryngologist].

A case of dirofilariosis is reported. The disease is believed to be caused by the contact with the cat that the patient brought in from Uzbekistan. The authors emphasize the importance of analysis of the medical history of the patients presenting with the pathology being considered, their medical examination, and correct interpretation of X-ray images of the paranasal sinuses taking into account the possibility of distribution of rare helminth species beyond their usual ranges.

Isolated periostitis as a manifestation of systemic vasculitis in a child: imaging features.

We report a case of isolated periostitis associated with Takayasu arteritis in a 10-year-old boy presenting with calf pain. Radiographs revealed a localized, thick periosteal reaction with irregular margin in the proximal left fibula. MRI revealed irregular thickening with enhancement of the periosteum in the proximal fibula and heterogeneous enhancement along vascular bundles in the calf. Isolated periostitis is a rare skeletal manifestation of systemic vasculitis that could be misdiagnosed as neoplastic or traumatic periosteal reaction.

Computed tomography findings of periostitis ossificans

Periostitis ossificans (PO) is a type of chronic osteomyelitis, an inflammation of cortical and cancellous bone. In the maxillo facial region, the mandible is most frequently affected. The cause of inflammatory subperiosteal bone production in PO is spread of infection from a bacterial focus (e.g.: odontogenic disease, pulpal or periodontal infection, and extraction wounds). This pathology is most commonin younger people (mean age of 13 years). Conventional radiographs are one of the most usefultools for diagnosis, but in some cases computed tomography (CT) has a key role in both diagnosis and identification of the tissues involved. This paper reports two cases of PO in which CT help edestablishing the suspicious etiology: a 12-year-old boy with PO of pulpal origin and a 14-year-old boy with PO of periodontal origin.

Periostitis and hypertrophic pulmonary osteoarthropathy: report of 2 cases and review of the literature.

OBJECTIVES: To demonstrate the clinical spectrum of hypertrophic osteoarthropathy (HOA). METHODS: We report 2 cases of HOA and performed a computer-assisted search of Medline/PubMed for the medical literature from 1960 to June 2008 using the keywords HOA, periostitis, and clubbing. These were also combined with the text words cancer, rheumatic disease, etiology, pathogenesis, hypothesis, transplant, and treatment. Only the English language literature, with pertinent information, was included. RESULTS: Our 2 cases include 1 HOA case with clubbing, in a patient with a right to left shunt from cryptogenic cirrhosis and interstitial lung disease, and 1 HOA case without apparent clubbing, in a patient with chronic lung transplant rejection secondary to tobacco smoking and related emphysema. Review of the literature has shown that HOA is associated with a wide variety of disorders, approximately 80% are found with primary or metastatic pulmonary malignancies. Various rheumatic diseases, such as systemic vasculitis, can also be associated with HOA. With respect to the pathogenesis, vascular endothelial growth factor, platelet-derived growth factor, and platelets may play crucial roles. Therapeutically, bisphosphonates, such as pamidronade or octreotide, may be tried to relieve symptoms in refractory cases. CONCLUSIONS: HOA, especially periostitis without clubbing, may go unrecognized. Involvement of vascular endothelial growth factor, platelet-derived growth factor, and platelets in the pathogenesis of HOA has been postulated and supported by recent data. HOA may present as a partial syndrome without clubbing and about 20% of cases have HOA without detectable malignancy. One of our cases represents the first report of the association of HOA with lung transplantation.
