[Postoperative and bacterial osteitis. New possibilities for therapy].

Current therapy concepts for post-trauma osteitis include radical debridement, stabilization of bone and soft tissue care using early flap transfers. With this more radical approach, the long term results are improved, however, total treatment time still is very long. In addition to the physical, mental and social consequences for the patient, treatment costs are also very high. Antibiotic therapy as an adjuvant is still standard and effective although the development of worldwide antibiotic resistance has increased treatment difficulties. One of the main aims of research is to reduce these problems or to prevent the development of osteitis entirely. However, research has not yet elucidated the complex immunologic changes involved. In addition, most results are obtained from animal studies and clinical investigations are required.

Condensing osteitis of the clavicle in a man.

Condensing osteitis of the clavicle is a rare, benign, usually painful condition leading to sclerosis of the medial end of the clavicle. In the English language literature, this has only been reported in women since its original description by Brower et al. in 1974 [1]. We report a clavicular lesion occurring in a man that is clinically, radiographically, and histologically identical to described cases of condensing osteitis.

Osteitis pubis: an unusual postpartum presentation.

INTRODUCTION: Osteitis pubis is a poorly understood and uncommon disorder rarely associated with spontaneous delivery. CASE REPORT: We present a case consistent with osteitis pubis that followed a normal vaginal delivery and where symptoms developed earlier than ever previously reported. DISCUSSION: The potential benefit of low molecular heparin is discussed.

[Central giant cell granuloma and osteitis fibrosa cystica of hyperparathyroidism. A challenge in differential diagnosis of patients with osteolytic jawbone lesions and a history of cancer].

BACKGROUND: Giant cell lesions of the bone present similar histological features. The differential diagnosis comprises central giant cell granuloma, giant cell tumor of bone, and osteitis fibrosa cystica (brown tumor) in combination with hyperparathyroidism. Since these lesions may mimic metastatic bone disease in patients with a history of cancer, a malignant process has to be considered. Since the treatment and prognosis of these entities-benign versus malignant osteolytic bone processes-differ greatly, definitive differential diagnosis is of utmost importance. CASE REPORT: Two patients presenting with osteolytic lesions of the maxilla are reported here. In both cases a history of cancer (breast and prostate) suggested bone spreading of these malignant tumors. The clinical and histological findings were similar in both patients. One lesion was diagnosed as central giant cell granuloma, the other was found to be brown tumour in osteitis fibrosa cystica as an initial manifestation of hyperparathyroidism. DISCUSSION: The presented cases demonstrate the difficulties in establishing the correct diagnosis of patients found to have osteolytic lesions of the jawbones which is critical for the appropriate management of these patients. The article discusses the different entities of osteolytic lesions of the jawbones and the necessary diagnostic and therapeutic approach.

Osteitis deformans (Paget's disease) in a Burmese python (Python molurus bivittatus)--a case report.

Osteitis deformans (Paget's disease of bone) is a chronic focal disorder of bone remodelling characterized by an initial increase in osteoclast-mediated bone resorption, with subsequent compensatory increase in new bone formation, resulting in a disorganized mosaic of woven and lamellar bone. In the Burmese python (Python molurus bivittatus) of this report, multifocal gross swellings involving the proximal third of the vertebral spine were observed and associated with anorexia, a relative inability to move or to fully extend the body, and to strike at prey. Serum biochemistry revealed elevated alkaline-phosphatase activity. Radiographic changes (irregular bone proliferation along the vertebral margins), computed tomography scan results (abnormal mineral density), and histopathological features (generalized thickening of the bony trabeculae at the expense of the intertrabecular spaces and irregular patches of lamellar bone with a characteristic "mosaic" pattern) indicated osteitis deformans.

[Meningitis and osteitis caused by Pasteurella multocida in a three-month-old infant].

Pasteurella multocida is usually responsible for local infections occurring after animal bites. It can also be responsible for meningitis in infants. A three-month old infant was admitted to hospital with a diagnosis of bacterial meningitis and hip osteitis. Cultures of cerebrospinal fluid, blood and joint liquid were positive to Pasteurella multocida. Licking from the family dog was the transmission mode in this case. Despite initial neurological complications, clinical evolution was favourable after three weeks of intravenous antibiotic therapy followed by an oral administration for three months. Pasteurella multocida meningitis is rare in infants. It can be associated with arthritis, osteitis and septicaemia. Besides animal bites, licking is also a mode of contamination.

Hyperparathyroidism with osteitis fibrosa cystica in the maxilla.

In hyperparathyroidism, skeletal changes occur in 13 per cent of severe and long-standing cases (Smith, 1979). These skeletal changes vary from generalized demineralization of bone in early cases to resorption of bone marrow and replacement by fibrous tissue with cystic changes, the latter being termed osteitis fibrosa cystica or brown tumour. These cystic tumours are rare and usually occur in the long bones. Osteitis fibrosa cystica rarely presents in the maxilla as the initial symptom of hyperparathyroidism.

[Osteitis diagnosis in a group of angiology patients: a comparison of X-ray and nuclear medicine studies].

PURPOSE: Of the study was to examine the ranking of radiographs and bone scans in the diagnosis of osteitis. PATIENTS AND METHODS: 115 patients with arterial occlusive disease in stage Fontaine i.v. were referred for examination of the peripheral skeletal parts of the lower extremity. 126 radiographs and bone scans were taken. The time between the two examinations was 10 days maximum to enable direct comparison. Leukocyte scintigraphy was employed as gold standard. RESULTS: The sensitivity of radiographs was 47% with a specificity of 91%. Sensitivity and specificity of bone scans was 78% for both values. The positive predictive values for radiographs and bone scans were 88% and 85%, the negative predictive values were between 80% and 97%. CONCLUSION: In the majority of cases osteitis can be diagnosed with relatively inexpensive methods such as conventional x-rays and bone scans. Only in unclear cases further examinations such as leukocyte scintigraphy or magnetic resonance imaging should supplement the diagnosis.

Radical sternectomy and primary musculocutaneous flap reconstruction to control sternal osteitis.

OBJECTIVE: Sternal osteitis after median sternotomy is associated with considerable morbidity and mortality. The use of muscle and omentum flaps has been proved as valid adjunct to combat these severe infections. In this study we present our experience with a more radical approach. METHODS: Sternectomy consisted of the resection of the entire sternum, including the costochondral arches and the sternoclavicular joints, and was followed by the repair of the defect with musculocutaneous flaps without any restabilization of the thoracic wall. Thirteen patients received a vertical rectus abdominis musculocutaneous flap, 14 patients received a pedicled latissimus dorsi musculocutaneous flap, and 12 patients received a free latissimus dorsi musculocutaneous flap (total of 40 flaps in 39 patients of 66 patients who required surgical revision for sternal osteitis of 6078 total patients with sternotomies). RESULTS: Two patients died within 30 days after the operation (early mortality of 5.1%); however, they did not die of sternal infection, which was cured without any recurrence in all cases. Seventeen patients (44%) required secondary, mostly minor operations for local complications. Despite some paradoxic chest movements, the patient satisfaction rating was unanimously high at the long-term follow-up (0.4 to 8.5 years, median 2.3 years). The short- and long-term complication rates were similar in the three groups. CONCLUSION: We conclude that radical sternectomy and immediate musculocutaneous flap repair provided definitive control of sternal infection in even the most severe cases, thus reducing infection-related mortality. The trade-off was a substantial rate of local complications; however, these did not cause any relevant morbidity.

Syphilitic osteitis in a patient with secondary syphilis and concurrent human immunodeficiency virus infection.

Destructive bone disease is a well-recognized complication of congenital and tertiary syphilis. Clinically significant osteitis and osteomyelitis are rare complications of primary or secondary syphilis in patients who are not infected with human immunodeficiency virus (HIV). We report a case of an HIV-infected man who presented with symptomatic, left ulnar osteitis as the initial manifestation of secondary syphilis. The patient's clinical course was complicated by a pathological fracture, but he responded to high-dose intravenous penicillin G therapy and surgical intervention. Results of physical examination on follow-up at 15 months were normal, and a serofast (rapid plasma reagin [RPR]) titer of 1:4 and a markedly decreased uptake on bone scintigraphy were observed. Our case report suggests that bone disease can represent an atypical manifestation of early acquired syphilis and that HIV-positive patients who present with orthopedic complaints or bone lesions should be evaluated for the presence of syphilitic bone disease.

Classification of non-bacterial osteitis: retrospective study of clinical, immunological and genetic aspects in 89 patients.

OBJECTIVE: To define non-bacterial osteitis (NBO) as a clinical entity possibly associated with autoimmune manifestations. Patients with sterile osteitis were analysed to develop diagnostic criteria. METHODS: A total of 89 patients with non-bacterial inflammatory bone lesions were observed for a median of 49 months. History, diagnostic imaging, laboratory and histological data were obtained. Mutation analysis in the genes PSTPIP1 and PSTPIP2 was performed. RESULTS: Patients had an onset of disease at a median age of 10 yrs [interquartile range (IQR) 7.5-12] and suffered a median period of 21 (IQR 9-52) months with a median of three foci per patient. Twenty percent of all the patients demonstrated associated autoimmune disorders, particularly of the skin and bowel. The majority of bone lesions were located in the vertebrae and metaphyses. Slight-to-moderate elevation of inflammation values were found in all the patients and antinuclear antibodies were elevated in 30%. Non-steroidal anti-inflammatory drugs (NSAIDs) were effective in 85% of the patients. HLA-B27 and Human Leukocyte Antigen-DR (HLA-DR)-classification did not differ from the general population. Autoimmune diseases in 40% of all the families, multiply affected family members, linkage to 18q21 and mouse models strongly indicate a genetic basis for NBO. We observed three different courses of disease regarding the duration of complaints, rate of complications and associated autoimmune manifestations leading to a new classification of NBO. CONCLUSIONS: Clinical analysis of our cohort leads us to define NBO as a distinct disease entity with three clinical presentations: acute NBO, chronic recurrent multifocal osteomyelitis or persistent chronic NBO. Diagnostic criteria were proposed to differentiate NBO from diseases with similar clinical presentation.

Radiation osteitis and insufficiency fractures after pelvic irradiation for gynecologic malignancies.

Damage to the pelvic bones after radiotherapy for gynecological malignancies is uncommon with megavoltage radiotherapy. It can be misdiagnosed as bony metastases and is a diagnosis of exclusion. We report 12 women, who were treated for endometrial or cervical carcinoma who developed osteitis, femoral head or neck necrosis, or insufficiency fractures of the acetabulum, pubic symphysis or sacroiliac bones after radiotherapy. Many had multiple areas of bone damage. The prescribed external beam dose ranged from 40.0 to 61.2 Gy. All but one patient developed bony discomfort or pain as a symptom. Bony changes of the pelvic girdle appeared between 6 months and 8 years after irradiation. Radiographic studies including plain films, CT or bone scans were performed in these patients and showed correlative changes. Bone scans showed increased radionuclide uptake in affected bones. The subsequent favorable clinical course and outcome with resolution of symptoms confirmed the diagnosis of radiation osteitis. Therapy recommendations are conservative with avoidance of weight-bearing, use of analgesics and physical therapy. Femoral head necrosis/fractures required arthroplasty. Proper shielding, use of multifield technique, treatment of all fields per day, and awareness of tolerance doses are recommended.

Osteitis caused by BCG vaccination.

A survey of 26 Czechoslovakian children diagnosed with BCG osteitis during 1981-1986 is presented. Mycobacterial culture was attempted in 19 cases with confirmation of bacillus Calmette-Guerin (BCG) Mycobacterium bovis strain in nine cases. Symptoms appeared approximately 17 months after vaccination; the proximal tibial end, distal femur, and proximal humerus were most affected. Although vaccination has been obligatory since 1953, a different vaccine was introduced in 1980, which led to the diagnosis of BCG osteitis in 1981. The vaccination doses, symptomatology, and methods of treatment are described. The risk of complications and a project for vaccination at later age are discussed.

Septic osteitis of the distal phalanx: findings and surgical treatment in 18 cases.

Eighteen cases of septic osteitis of the distal phalanx were diagnosed clinically and confirmed at surgery over a 6 year period (1990-1996). Focal bone lysis was the most common radiographic finding. Sequestra were identified in 4 horses, one of which was associated with a fractured plantar process. All the horses were treated surgically with open debridement. The septic process recurred in 4 horses: one was subjected to euthanasia due to navicular bursa infection, secondary to a pathological fracture, the other 3 horses responded to further debridement. A pathological fracture occurred in another horse. All the survivors were not lame 3 months post operatively, although complete healing took 1-12 months. Long term follow up was available in 14 cases. One was retired, all the other horses were back in work at a similar level of performance. This series indicates that surgical treatment of septic pedal osteitis carries a fair to good prognosis despite a high rate of post operative complications and convalescence period of up to 12 months.

Relationship of secretion pattern and MPB70 homology with osteoblast-specific factor 2 to osteitis following Mycobacterium bovis BCG vaccination.

Significant homology was found between MPB70 and each of four repeat domains of osteoblast-specific factor 2 (OSF-2). Two internal homology regions within each repeat domain of OSF-2 presumed to be related to the active site(s) of this bone adhesion molecule showed the highest homology. A literature search concerning osteitis after Mycobacterium bovis BCG vaccination in neonates revealed that MPB70-high-producer substrains were associated with an increased incidence of osteitis following vaccination. These observations indicate that the function of MPB70 is related to the interaction between bacilli and the host following vaccination or infection with mycobacteria.

Clinical features of 53 cases with pustulotic arthro-osteitis.

We have described clinical features of 53 cases with pustulotic arthro-osteitis. Anterior chest wall symptoms such as intersterno-costoclavicular or manubriosternal lesions were observed in all of 53 cases. Spondylitis or spondylodiscitis was found in 18 cases. Sacroiliitis resembling ankylosing spondylitis was seen in 7 cases. Peripheral inflammatory arthritis was seen in 14 cases, which were of nonerosive, of oligoarthritis type, and cured within 1 to 2 months, leaving no residue. HLA B27 was never found, and RAW factor was negative. Histological examinations revealed nonspecific chronic inflammation of bone and soft tissue. Pustulotic arthro-osteitis is apparently distinct from known rheumatic diseases such as rheumatoid arthritis, ankylosing spondylitis, psoriatic arthritis, and Reiter's disease. We have proposed that this condition should be classified as a member of the "seronegative spondylo-arthritis' group as designated by Wright and Moll.
