Treatment of symphysitis pubis with one unique iv injection of Ibandronate: report of two cases

Objective: Osteitis pubis is a noninfectious painful inflammatorydisorder of the symphysis pubis. Etiologic factors are numerous, themost common are: osseous extension of adductor, enthesis due tosport overuse, irritation after urological and abdominal procedures,and systemic inflammatory disorders in particularspondylarthropathies. Many cases are idiopathic. The symptomsconsist of regional chronic mechanical and sometime nocturnal pain.Diagnosis is usually confirmed by either bone scintigraphy or by MRI.There are no standard treatments but conservative approachesincluding rest and NSAIDS are generally recommended. In 2001, agood clinical and radiological response of three refractory cases with3 to 6 monthly perfusions of pamidronate was reported [1].Ibandronate is a much more powerful and long-lasting bisphosphonatethan pamidronate, and has not yet been reported in literature to ourknowledge in this indication.Patients and Methods: We present two cases of idiopathic origin:one woman (63 years old) and one man (36 years old).The symptomswere present >3 months in the first patient and one year in the second.The diagnosis was confirmed by MRI which showed bone edemaon both sizes of symphysis and in the second case bony erosionsadjacent to the joint were seen. Both cases failed to respond toconservative measures. Both patients received one single direct ivInjection of 3 mg of Ibandronate.Results: The injections resulted in a rapid (within a few days)resolution of pain that lasted more than 6 months in both patients.No side effects were observed. In the first case, an isotope bone scanperformed 4 months after the injection showed no residual uptake. Thesecond patient had a repeated MRI after 6 months. It demonstrated anattenuation of bone edema compared to the first MRI.Conclusion: IV Ibandronate may constitute a safe and effectivetreatment option for patients with refractory osteitis pubis.References1 Maksymowych WP, Aaron SL, Russell AS.

The girl from the Church of the Sacrament: a case of congenital syphilis in XVIII century Lisbon

Syphilis is a sexually or congenitally transmitted infectious disease with an impact on the health of human populations that has undergone important cycles in different countries and periods of history. Its presence was first diagnosed in Europe in the late XIV century. In Portugal, although there are various written records of the infection in the last centuries, there are rare references to it in archeological findings (mummified bodies are also rare in Portugal). The current study describes a probable case of congenital syphilis in an 18-month-old girl buried in the Church of the Sacrament in Lisbon. Her body, dating to the XVIII century, was found mummified together with dozens of others, still not studied. Symmetrical periostitis of the long bones, osteitis, metaphyseal lesions, left knee articular, and epiphyseal destruction, and a rarefied lesion with a radiological appearance compatible with Wimberger's sign all point to a diagnosis of congenital syphilis. The diagnosis of this severe form of the infection, possibly related to the cause of death in this upper-class girl, calls attention to the disease's presence in XVIII century Lisbon and is consistent with the intense mobilization at the time in relation to the risks posed by so-called heredosyphilis. It is the first case of congenital syphilis in a child reported in archeological findings in Portugal, and can be correlated with other cases in skeletons of adults buried in cemeteries in Lisbon (in the XVI to XVIII centuries) and Coimbra (XIX century). Finally, this finding highlights the need to study the entire series of mummified bodies in the Church of the Sacrament in order to compare the paleopathological findings and existing historical documents on syphilis, so as to expand the paleoepidemiological knowledge of this infection in XVIII century Lisbon.

L'ostéolyse expansive familiale : manifestations otologiques et dentaires d'origine génétique

RESUME Nous rapportons l'étude d'une famille de 49 membres sur 5 générations. Parmi 35 membres étudiés, 18 sont atteints d'Osteolyse Expansive Familiale (OEF). L'OEF est une dysplasie osseuse génétique rare, autosomique dominante, dont les altérations locales et générales du squelette ont une distribution périphérique prédominante qui devient manifeste à partir de la deuxième décennie de vie. Une résorption ostéoclastique progressive, accompagnée d'une faible activité ostéoblastique, est à l'origine d'une expansion médullaire osseuse. Cette dernière est caractérisée par une raréfaction de la moelle osseuse qui est remplacée par du tissu fibreux et de la graisse. L'amincissement de la moelle osseuse aboutit à des déformations invalidantes, sévères et douloureuses du squelette, avec tendance aux fractures spontanées. La première manifestation clinique de la maladie est une surdité de transmission très précoce résultant d'une lyse de la chaîne ossiculaire. Radiologiquement, il existe toujours une pneumatisation marquée de la mastoïde et du rocher. Les dents montrent des signes importants de résorption osseuse au niveau de la région apicale et/ou du collet, dont l'aspect est caractéristique et unique. La phosphatase alcaline sérique, l'hydroxyproline et la deoxypiridoline urinaire sont élevées à des taux variables. Le taux de calcium et d'hormone parathyroïdienne est normal. Le traitement par les diphosphonates, la calcitonine et la vitamine D est inefficace. Histologiquement, l'OEF présente des similitudes avec la maladie de Paget, mais l'âge de début, la distribution des lésions osseuses, les altérations dentaires et de l'oreille moyenne, ainsi que la progression clinique sont différents. Il en va de même pour la dysplasie fibreuse, l'ostéite fibro-kystique et l'ostéogénèse imparfaite. Le gêne responsable de la maladie se localise dans la région du chromosome 18q21-22. Récemment, des mutations du TNFRSF 11A, gêne qui codifie le RANK, ont été identifiées comme étant la cause de l'OEF. La duplication de la 18ème paire de base au niveau de l'exon 1 suggère qu'il correspond au site de l'anomalie. La technique chirurgicale et les résultats audiométriques à court et long terme de 13 interventions chez 8 patients sont présentés. ABSTRACT Objectives: Familial Expansive Osteolysis (EEO) is a rare autosomal dominant bone dys¬plasia. The disease can show general and focal skeletal alterations, the latter having a pre¬dominantly peripheral distribution. Onset occurs after the second decade of life. Patients and methods: We present the study, of 30 years, of a family consisting of 49 members covering five generations. Results: Among the 35 members studied, 18 have familial expansive osteolysis (FEO). The first clinical sign of the condition is transmission deafness at an early age. The features of the teeth has a unique and characteristic appearance. Thinning of the corti¬cal bone leads to severe, painful, disabling deformities. Serum alkaline phosphatase, and urinary hydroxyproline and deoxipyridinoline are elevated. Calcium and parathyroid hor¬mone are normal. Treatment with diphosphonates, calcitonin and vitamin D has been unsuccessful. We present the surgical technology and the results to short and long term of 13 interventions on 8 patients. Conclusion: Progressive osteoclastic reabsorption accompanied by weak osteoblastic activ¬ity results in medullary expansion characterized by rarefaction of the bone marrow, which is replaced by fibrous tissue and fat. FE0 is histologically similar to Paget disease, but the age of onset, the distribution of the bone lesions, the dental and middle ear alterations, and the clin¬ical progression are different. These features also differentiate FE0 from fibrous dysplasia, fibrocystic osteitis and imperfect osteogenesis. The gene responsible for EEO is located in the 18q21-22 chromosome region. Mutations in TNFRSF11A, the gene encoding receptor activa¬tor of nuclear factor-kappa-B (RANK), has been recently identified as the cause of FEO. A duplication of 18 base pairs in exon 1 of the TNFRSF11A gene suggests that this corresponds to the site of the anomaly and can be considered a "hot spot" for mutations.

Septic arthritis of the pubic symphysis caused by Streptococcus mitis.

Septic arthritis of the pubic symphisis is distinguished from osteitis pubis by positive cultures. The symptoms, physical examination and laboratory findings of these two conditions are comparable. We present a case of 57-year-old woman with septic arthritis of pubic symphisis caused by Streptococcus mitis, a commensal oral flora that belongs to viridans group streptococci, which normally reside in the oral cavity, the gastrointestinal and the urogenital tract.

Le fixateur externe dans les lésions traumatiques graves du bassin: résultats à propos de 20 cas consécutifs [External fixator in severe traumatic injuries of the pelvis: results apropos of 20 consecutive cases]

From August 91 to December 94, 20 external fixators were used for severely injured patients (avg. ISS 25.2). The fractures were essentially open book with or without lateral compression and vertical lesions. The indication for fixation was treatment of shock and stabilization in 8 cases, stabilization alone in 9 cases, and in 3 cases as complementary fixation after internal fixation of posterior lesions. The fixation of the pelvis was effective on the amount of blood loss. One acetabulum fracture required surgery, two patients had internal fixation for loss of reduction and two others for late pubic and posterior pain. The clinical results are good; they are more related to the severity of the initial lesion than to the mode of fixation or the quality of the reduction. No superficial sepsis or osteitis was observed in relation to the pins.

Salmonella epidural abscess in sickle cell disease: failure of the nonsurgical treatment.

In patients suffering from sickle cell disease (SCD), bone is a preferred site of infection. We report the case of a five-year-and-eight-month-old black African boy with homozygous-SS disease who developed a cranial epidural abscess. This intracranial infectious complication originated from a Salmonella enteritidis osteitis of the frontal bone. Antibiotic treatment alone did not control the disease, so surgery was necessary to remove the necrotic bone and to evacuate the epidural pus. The numerous factors interfering with normal healing of a septic focus in sickle cell anemia, particularly in this previously undescribed intracranial complication, emphasize the need for a primary and early surgical treatment in similar situations.

Les fractures du pilon tibial. Etude rétrospective à long terme de 51 fractures traitées par réduction sanglante et ostéosynthèse [Fractures of the tibial pilon. Long-term retrospective study of 51 fractures treated with open reduction and osteosynthesis].

PURPOSE OF THE STUDY: Fracture of the tibial pilon is a rare injury and its treatment remains difficult. The aim of this study was to report the complications and long term results of internal fixation using a technique which respects soft tissues and in which little material was used. MATERIAL: From 1985 to 1990, 48 patients with 51 fractures of the tibial pilon were treated by open reduction and internal fixation. All patients were submitted to a clinical and radiological review. METHODS: Both the Rüedi/Allgöwer and the AO-classification were used and determined by standard X-rays. Surgical procedure was performed with a 2 or 3 1/3 tube AO-plates and the peroneus was always fixed if fractured. Intraoperative reconstruction was analyzed. Subjective and objective scoring were used according to Olerud and Molander and the ankle arthritis was scored according to the classification determined by the SOFCOT in 1992. RESULTS: A minimal follow-up of 1 year for all cases was obtained, based on our own files. Thirty-eight patients (40 fractures) were evaluated after an average period of 88 months (56 to 124 months). Five patients developed cutaneous infection, three developed deep infection and four developed superficial skin necrosis. One aseptic non-union necessitated reoperation after 14 months. Two ankles had joint fusion after 19 and 25 months respectively due to severe arthritis. In six cases infectious and non-infectious complications led to surgical revision. According to the Olerud and Molander score, 15 per cent of the results were excellent, 45 per cent were good, 30 per cent were fair and 10 per cent poor. DISCUSSION: Literature shows a wide range of results following this surgical procedure. This is due to the difference in the type of trauma, classification system used, material used for the internal fixation and method of evaluation. The classification system of Rüedi and Allgöwer is the most commonly used but has a rather subjective tendency, especially between type II and type III. Treatment is difficult, especially for comminutive fractures associated with soft tissue damage. In this case, open reduction and internal fixation could increase iatrogenic lesions. For this reason surgical procedure can be delayed for several days, little material is used and soft tissue manipulation is reduced to minimum. In other study reports, the use of external fixation with or without minimal internal fixation have produced less complications without improving long term results. CONCLUSION: Analysis and comparison of study reports are difficult because of the absence of consensus in classification system and evaluation methods. The AO-classification, apparently the most objective, will probably be more and more used in the future. Treatment must be adapted to the bony lesion and soft tissue damage. Open reduction and internal fixation must be reserved for a specific group of lesion.

Chronic nonbacterial osteomyelitis in children: a retrospective multicenter study.

BACKGROUND: To determine the clinical presentation, current treatment and outcome of children with nonbacterial inflammatory bone disease. METHODS: Retrospective multicenter study of patients entered into the Swiss Pediatric Rheumatology Working Group registry with a diagnosis of chronic nonbacterial osteomyelitis (CNO) and synovitis acne pustulosis hyperostosis osteitis (SAPHO) syndrome. The charts were reviewed for informations about disease presentation, treatment, course and outcome. RESULTS: Forty-one children (31 girls and 10 boys) from 6 pediatric hospitals in Switzerland diagnosed between 1995 and 2010 were included in the study. The diagnosis was multifocal CNO (n = 33), unifocal CNO (n = 4) and SAPHO syndrome (n = 4). Mean age at onset of CNO was 9.5 years (range 1.4-15.6) and mean follow-up time was 52 months (range 6-156 months). Most patients (n = 27) had a chronic persistent disease course (>6 months), 8 patients had a course with one or more relapses and 6 patients had only one episode of CNO. Forty nine percent had received at least one course of antibiotics. In 57% treatment with nonsteroidal anti-inflammatory drugs (NSAID) was sufficient to control the disease. Twelve out of 16 children with NSAID failure subsequently received corticosteroids, methotrexate, TNF α inhibitors, bisphosphonates or a combination of these drugs. CONCLUSIONS: In a multicenter cohort of 41 children 22% started with unifocal lesion with a significant diagnostic delay. A higher proportion presented with chronic persistent disease than with a recurrent form. An osteomyelitis in the pelvic region is significantly associated with other features of juvenile spondylarthritis.

Ivory vertebra: imaging findings in different diagnoses

Abstract Low back pain is often managed at all levels of healthcare. In general, diagnostic investigation begins with radiography of the lumbar spine. In addition to the most common findings, radiologists can identify increased density of a vertebral body, referred to as ivory vertebra. The objective of this study was to describe the main diseases that can present with this radiologic sign, such as Hodgkin lymphoma, Paget's disease, metastatic prostate cancer, breast cancer, and osteomyelitis. It is extremely important that radiologists be aware of this finding in order to inform the requesting physician of the possible etiologies, given that it can be the initial radiologic presentation for these diseases.

El costo de la atención ambulatoria del lupus eritematoso sistémico en Colombia. Contrastes y comparaciones con otras poblaciones.

Introducción: el lupus eritematoso sistémico (LES) es considerado una enfermedad de alto costo. La expresión clínica de la enfermedad depende de la ubicación geografía y la etnicidad. El objetivo de este estudio fue el calcular los costos ambulatorios relacionado al LES en una cohorte colombiana, identificar los predictores de costos y comparar nuestro resultados con otras poblaciones. Métodos: Se realizó una aproximación de tipo prevalencia en 100 pacientes LES en quienes se evaluaron los costos directos médicos, directos no médicos, indirectos e intangibles. Todos los costos médicos fueron evaluados usando una metodología abajo hacia arriba. Los costos directos fueron valorados desde una perspectiva social usando una metodología de micro-costeo. Los costos indirectos se evaluaron mediante una aproximación de capital humano, y los costos intangibles calculados a partir de los años de vida ajustados por calidad (AVAC). Se analizaron los datos por medio de un análisis multivariado. Para comparaciones con otras poblaciones todos los costos fueron expresados como la razón entre los costos y producto interno bruto nacional per cápita. Resultados: La media de costos totales fue 13.031±9.215 USD (ajustados por el factor de conversión de paridad del poder adquisitivo), lo cual representa el 1,66 del PIB per capita de Colombia. Los costos directos son el 64% de los costos totales. Los costos médicos representan el 80% de los costos directos,. Los costos indirectos fueron el 10% y los costos intangibles el 25% de los costos totales. Los medicamentos representaron el 45% de los costos directos. Mayores costos se relacionaron con el estrato socioeconómico, seguro médico privado, AVAC, alopecia, micofenolato mofetilo, y terapia anticoagulante. Los costos directos ajustados de los pacientes con LES en Colombia fueron mayores que en Norte América y en Europa. Conclusiones: el LES impone una carga económica importante para la sociedad. Los costos relacionados con la atención médica y AVAC fueron los principales contribuyentes al alto costo de la enfermedad. Estos resultados pueden ser referencia para determinar políticas en salud pública así como comparar el gasto en salud de forma internacional.

Clinical, radiographic, biochemical and histological findings of florid cemento-osseous dysplasia and report of a case

A displasia cemento-óssea florida tem sido descrita como uma condição que afeta tipicamente os maxilares de mulheres negras de meia idade. Ela geralmente se manifesta como múltiplas massas radiopacas semelhantes ao cemento distribuídas nos maxilares. Esta condição também tem sido classificada por vários autores como cementoma gigantiforme, osteomielite esclerosante crônica, osteíte esclerosante e massas de cemento escleróticas. Os autores apresentam um caso de displasia cemento-óssea florida não complicada em uma mulher negra de 48 anos de idade. Múltiplas massas escleróticas com bordas radiolúcidas na mandíbula foram identificadas radiograficamente. Os achados histopatológicos revelaram formação de massas escleróticas densas calcificadas semelhantes ao cemento. Todos os aspectos clínicos, radiográficos, bioquímicos e histológicos foram sugestivos do diagnóstico de displasia cemento-óssea florida.

Advancements in the knowledge of induced tooth movement: idiopathic osteosclerosis, cortical bone and orthodontic movement

Movimentar ortodonticamente os dentes por áreas densas do trabeculado ósseo e pelas corticais pode requerer uma redução na intensidade e/ou na concentração das forças aplicadas. em parte, as forças ortodônticas aplicadas são dissipadas e reduzidas pela deflexão óssea que ocorre pelo discreto grau de elasticidade do tecido ósseo em condições de normalidade. Nas áreas de trabeculado denso e nas corticais, essa deflexão deve ser irrisória ou inexistente. Se não houver uma redução na intensidade das forças nessas regiões citadas, toda a força incidirá sobre a estrutura do ligamento periodontal, aumentando o risco de morte dos cementoblastos, hialinização e reabsorções radiculares. Novos trabalhos poderiam avaliar a prevalência dessas consequências em casuísticas selecionadas para essa finalidade, que, assim, deixariam de ser observações aleatórias.

Unusually rapid growth of brown tumour in the mandible after parathyroidectomy associated with the presence of a supernumerary parathyroid gland

The aim of this study is to report the case of a quick growing brown tumour in the jaw after a parathyroidectomy due to the presence of a rare fifth parathyroid gland. The patient had chronic renal disease and the diagnosis was tertiary hyperparathyroidism. Thirty days after the parathyroidectomy, the patient returned with a significant increase in the tumour size. The suspicion of a supernumerary gland was confirmed by parathyroid scintigraphy. The treatment of brown tumour is dependent on the treatment of the hyperparathyroidism. However, curettage should be considered if a large lesion is disturbing mastication. In conclusion, this case should attract the attention of general practitioner dentists, since they may be the first professionals who have contact with the patient with a brown tumour in the jaws. Likewise, this case emphasises the importance of knowing the type of hyperparathyroidism involved to allow for effective treatment planning. © 2011 European Association for Cranio-Maxillo-Facial Surgery.
