Diagnostic points and possible origin of osteomyelitis in synovitis, acne, pustulosis, hyperostosis and osteitis (SAPHO) syndrome: a radiographic study of 77 mandibular osteomyelitis cases.

OBJECTIVES: To find diagnostic points and to identify the origin of osteomyelitis in synovitis, acne, pustulosis, hyperostosis and osteitis (SAPHO) syndrome. METHODS: Fifty-two patients with mandibular suppurative osteomyelitis and 25 patients with mandibular osteomyelitis in SAPHO syndrome were included in the study. Radiographic patterns of the lesion, types of periosteal reaction and the presence of external bone resorption and bone enlargement were investigated in each case and compared between the two entities. RESULTS: Suppurative osteomyelitis demonstrated an osteolytic pattern and a lamellated type of periosteal reaction, whereas SAPHO syndrome revealed a mixed-pattern, solid-type periosteal reaction, external bone resorption and bone enlargement. CONCLUSIONS: Radiographic examination is suggested to be convenient and a useful diagnostic method of differentiating osteomyelitis in SAPHO syndrome from suppurative osteomyelitis. The periosteum is suspected to be the original site of osteomyelitic lesions in SAPHO syndrome.

Plasminogen activators and inhibitor type-1 in alveolar osteitis.

Alveolar osteitis (AO) is characterized by excess fibrinolysis, leading to early dissociation of the clot that normally follows tooth extraction. Nonetheless, scarce information is available on the fibrinolytic system in AO. In this study, we report on the differential composition of postextraction wound healing tissue and of peri-alveolar gingival epithelium from normal healing and AO patients in terms of plasminogen activators, plasminogen activator inhibitor-type 1, and urokinase-type plasminogen activator receptor. Plasminogen activators were studied by overlay zymography, western blotting, and enzyme-linked immunosorbent assay (ELISA). Plasminogen activator inhibitor-type 1 and urokinase receptor were measured by ELISA. In AO, the fibrinolytic activity of wound healing tissue was accounted for by an increase ( approximately 85%) of urokinase-type plasminogen activator, whereas tissue-type plasminogen activator was unchanged. Plasminogen activator inhibitor-type 1 showed a 6.7-fold increase in AO. These results point to key roles of urokinase in AO hyper-fibrinolysis and of plasminogen activator inhibitor type-1 in slowing down the healing response. Peri-alveolar gingival epithelium in AO showed an overall decrease of all the components of the fibrinolytic system, including the urokinase receptor, which indicates a decrease of the migration properties of epithelial cells.

Disseminated arthritis and osteitis by Candida albicans in a two month old infant receiving parenteral nutrition.

The case of a two-month -old female infant, who after a severe diarrhoea treated with prolonged intravenous infusion in peripheral veins alternated with total parenteral feeding, developed a Candida albicans septicemia (accompanied by disseminated intravascular coagulation syndrome) is reported. The course of her disease was also complicated by multiple foci of osteoarthritis in both knees, in the left hip and in several long-bones. Radiographically the foci of Candida osteitis appeared as fine erosion of the cortex and minute round areas of osteolysis in the spongiosa, surrounded by a rim of perifocal sclerosis. During the acute stage of Candida sepsis a transitory cellular immunodeficiency was present. Treatment of Candida infection by 5-fluorocytosine was followed by complete recovery.

Alveolar osteitis (dry socket) in a dog: a case report.

Following extraction of a maxillary left first molar tooth in an eight year-old retriever, the dog re-presented five days later because of oral pain, which did not respond to analgesic therapy. The extraction site contained a foul-smelling fluid, but did not contain a clot or granulation tissue. Alveolar osteitis (dry socket) was diagnosed. The alveolus was curetted and flushed, and the dog was given cefalexine and prednisolone. The alveolus was filling with healthy granulation tissue one week later and the dog was no longer in pain.

Case report. synovitis, acne, pustulosis, hyperostosis and osteitis (SAPHO) syndrome.

A case of the SAPHO (synovitis, acne, pustulosis, hyperostosis and osteitis) syndrome in a 35-year-old woman is presented. Ignorance of this entity on the part of the physicians treating the patient may have contributed to her having repeated diagnostic procedures and treatment, some of which may have been unnecessary. Dentists are encouraged to suspect the SAPHO syndrome when they encounter a patient with mandibular osteomyelitis together with symptoms involving other bones and skin lesions such as pustulosis or psoriasis.

Diffuse chronic sclerosing osteomyelitis and the synovitis, acne, pustolosis, hyperostosis, osteitis (SAPHO) syndrome in two sisters.

Two sisters with diffuse chronic sclerosing osteomyelitis of the mandible and the humerus and the synovitis, acne, pustolosis, hyperostosis and osteitis syndrome (SAPHO syndrome) are presented. The diagnoses of diffuse chronic sclerosing osteomyelitis at the age of 12 years and 27 years, respectively, were based on typical medical history, clinical symptoms and radiographic, histologic and scintigraphic findings. Because skin lesions and scintigraphic enhancement of the sternoclavicular joints with hyperostosis were present, a SAPHO syndrome was diagnosed in both sisters. Microbiological cultures of biopsy specimens revealed coagulase-negative Staphylococcus aureus at the humerus and Haemophilus parainfluenzae, Streptococcus, Actinomyces and Veilonella species at the mandible. Repeated operative procedures, including decortications, resection and reconstruction, and multiple histologic and microbiologic studies were performed over a period of up to 20 years. Since HLA typing yielded identical gene loci, we suggest that hereditary and autoimmune factors may play a role in the pathogenesis of these cases.

Alveolar osteitis: a review of its etiology, prevention, and treatment modalities.

Alveolar osteitis (AO), commonly referred to as dry socket, is by far the most common complication following dental extraction. It represents a breakdown of healing after clot formation but before wound organization. This paper will review the literature associated with the etiology of AO, the risk factors which contribute to AO, and treatment regimens for AO once it is diagnosed. It will conclude with a summary of the current measures that hold the highest promise for the prevention of AO.

[A case of pustulotic arthro-osteitis with secondary amyloidosis].

A 63-year-old man with a history of Pustulosis Palmaris et Plantaris since 1960 was suffered from lumbago and anterior chest pain in 1973. Chest X-ray film showed inter-sterno-costo-clavicular ossification. Spondylodiscitis, Syndesmophyte of lumbal spine, Sacro-iliitis were seen by abdominal X-ray film. He was admitted to near hospital with generalized edema and urinary protein (10-20 g/day) in April 1986. Laboratory studies showed hypoproteinemia, positive C-reactive protein, high serum amyloid A protein(240 ng/100 microliters) and negative HL-A B27. He was diagnosed Pustulotic arthro-osteitis and Secondary Amyloidosis by renal biopsy and rectal biopsy in 1987. He was treated with high-dose oral prednisolone(60 mg/day)and dimethyl sulfoxide. After treatment, Edema and Nephrose improved. Increasement of renal function was not observed.

Condensing osteitis of the clavicle. Report of two cases and review of the literature.

Condensing osteitis of the clavicle, better defined as aseptic enlarging osteosclerosis of the clavicle, is a rare and benign idiopathic lesion. It is probably of degenerative or mechanical origin, and is most commonly seen in middle-aged women as a tender swelling over the medial one-third of the clavicle. Although the clinical features may be confusing and nonspecific, the typical radiographic and histopathological findings will mostly lead to a correct diagnosis of this disorder. The differential diagnosis is quite extensive. Most difficult to differentiate are: avascular necrosis of the medial clavicular epiphysis, sternoclavicular orsteoarthritis, low-grade chronic osteomyelitis, sternocostoclavicular hyperostosis and Tietze's syndrome. The authors recommend a thorough physical examination and technical tests, not only in subjects with pain of the clavicle but also in those with shoulder pain only, especially in women who are in their fourth decade. Treatment with analgesic and anti-inflammatory medications may be variably effective. In refractory cases excisions of the medial one-third of the clavicle may be indicated to offer better relief of symptoms as well as to exclude malignancy.

[BCG osteitis].

After first describing the course of BCG osteitis in young children, the problems associated with the routine prophylactic BCG inoculation in countries with a low incidence of tuberculosis are discussed. There is good reason to draw attention to the recommendation of the Inoculation Commission attached to the Federal Health Office calling to the fact that newborn infants should be inoculated only if they belong to the high-risk groups.

[Preliminary treatment of the recipient site and healing of open spongiosa transplant in post-traumatic osteitis].

On the occasion of a new surgical procedure 48 patients with chronic osteitis were treated with a new antiseptic called "Lavasept" and open spongiosa-treatment. The spongiosa-filling was covered with saturated Lavasept-dressing which were changed once or twice daily till the spontaneous wound-healing occurred. None of the 48 patients has shown complications of the wound-healing or a relapse till today.

HLA antigens in osteitis condensans ilii and ankylosing spondylitis.

Using a standard microdroplet lymphocyte cytotoxicity test for tissue typing, the distribution of the HLA antigens was determined in 37 female patients; 25 with osteitis condensans ilii (OCI) and 12 with ankylosing spondylitis (AS). Although low back pain was a common feature of OCI, none of these patients exhibited the limitation of spinal involvement, radiological evidence of spondylitis, or progressive clinical course seen in the AS group. Four of the 25 patients with OCI (16 per cent) were B27 positive vs 11 of the 12 patients with AS (92 per cent). These results suggest that OCI is not a variant of AS in women.

[Corynebacterium acnes osteitis. A case in a child].

The authors report a case of Corynebacterium acnes osteitis in an 11 year old girl, involving the upper of the right tibia. The lesion resembled a malignant tumour radiologically and tuberculosis histologically. Scintigraphy revealed involvement of the seventh right rib. 3 months treatment with Pristinamycin resulted in cure.

[Centrosomatic tuberculous vertebral osteitis. General review apropos of 4 cases].

Defined by the localisation of tuberculous infection in the vertebral body, centrosomatic tuberculous vertebral osteitis, which is rarer than Pott's spondylodiscitis, is more frequently seen in the cases of multifocal tuberculosis occurring preferentially in male black African immigrants approximately 30 years of age. Central area destruction, which has been the initial and pathognomonic radiological sign since its description by Calve and Galland , may progress towards wedging of the vertebral body, and even to its complete disappearance, accompanied by reactive osteocondensation . Infection from this particular localisation of vertebral tuberculosis may spread via arterial branches posterior to the vertebral bodies.

Intravenous calcitriol can increase bone mass in hemodialysis patients with osteitis fibrosa.

Intravenous calcitriol administration (IVC) suppressed parathyroid hormone (PTH) secretion and improved osteitis fibrosa (OF) in long-term hemodialysis (HD) patients, although it did not increase the mineralized bone area or the mineral apposition rate. We observed the long-term effects of IVC on OF in 8 HD patients. Bone biopsy of 7 patients revealed increased bone turnover and decreased bone mass. One microgram of calcitriol was given intravenously three times weekly after each HD session for 12 months. The dose was adjusted to maintain the serum corrected calcium level at < 11.5 mg/dl. Dual-energy X-ray bone absorptiometry (DEXA), 3rd lumbar vertebra bone density by quantitative computed tomography (QCT), and biochemical data were taken before IVC, and after 6 and 12 months of IVC. Seven HD patients were given 0.5 microgram/day 1 alpha-cholecalcitriol as controls. The serum corrected calcium levels were 9.9 +/- 0.3 (mean +/- SE) and 11.1 +/- 0.2 mg/dl at 0 and 12 months, respectively (p = 0.06). The serum phosphate levels were 6.2 +/- 0.7 and 6.6 +/- 0.6 mg/day at 0 and 12 months, respectively (p = 0.56). The serum intact PTH levels were 928 +/- 281 and 617 +/- 192 (p = 0.016) at 0 and 12 months, respectively. The bone mass of the 3rd lumbar vertebra measured by QCT was 195 +/- 17 and 218 +/- 186 g/cm3 at 0 and 12 months, respectively (p = 0.156). The bone mass of the trunk measured by DEXA was 660 +/- 44 and 706 +/- 32 g and 0 and 12 months, respectively (p = 0.156). These parameters did not change in controls. Sequential bone biopsy in 3 cases also supported these changes. We conclude that IVC not only suppresses bone turnover, but that it also restores decreased bone mass in HD patients with OF.

[Acquired hyperostosis syndrome (so-called pustular arthro-osteitis). Review of the literature including 73 personal cases].

The acquired hyperostosis syndrome (AHS) (best known synonym: pustulotic arthro-osteitis) is a system disease of the supporting and gliding tissue with sites of predilection characterized by inflammation-induced bony reconstruction of positive balance. This syndrome is affiliated with the seronegative spondylarthropathies. The main finding is the sternocostoclavicular hyperostosis in about 80% of patients. Focal hyperostoses also occur on the skeleton of truncus and extremities and joints. AHS is accompanied by psoriasiform and acneform dermatoses. Overlapping findings with spondylitis ankylosans are reported. Terminology, aetiology, nosology, pathogenesis, histomorphology, clinical and laboratory findings, complications, imaging diagnostic, differential diagnosis and therapy of AHS are discussed. Knowing AHS helps to prevent misdiagnoses (as especially bacterial osteomyelitis, spondylitis, osteoplastic tumor and metastases) and interventional diagnostic procedures.
