Vertebral biopsies were performed in 28 patients, 17 males and 11 females, because of vertebral body and disc changes between June 1978 and May 1982. In two patients biopsy was performed in two segments. Punctures were done in local and superficial anaesthesia of the vertebral body periosteum during continuous fluoroscopy control using Jamshidi's instrumentation. Aspiration and tissue cylinders were evaluated histologically and bacteriologically. There were no complications among the 8 thoracic and 22 lumbar biopsies. A histologic diagnosis could be established in 22 cases (78.6%): plasmocytoma (n = 2), spontaneous deformation of the spine in osteoporosis (n = 3), Scheuermann's disease (n = 1), specific (n = 2) and nonspecific (n = 14) spondylitis. Demonstration of bacteria was possible in 5 out of the 16 cases of spondylitis (31.25%): in two cases tubercle bacilli were demonstrated and once each salmonella group B, Haemophilus aphrophilus and coagulase-negative staphylococci. Only in 6 cases a diagnosis could not be established from the biopsy material.

Osteomyelitis of the frontal bone may be associated with a purulent collection under the periosteum, causing swelling and edema over the forehead, a condition known as Pott's puffy tumor. We describe an 83-year-old man with a Pott's puffy tumor due to Haemophilus influenzae that was successfully treated with surgery and antibiotics. A review of 22 cases of Pott's puffy tumor shows that this condition usually occurs in children, is spread from frontal or ethmoid sinusitis, and is usually due to streptococci, staphylococci, or anaerobes. Suppurative complications such as epidural, subdural, and intracerebral abscesses are common. Only seven cases of Pott's puffy tumor in adults have been reported, and only one of these cases was caused by H. influenzae. Surgical drainage and antibiotic therapy remain standard therapy for this condition.

Experimental studies have shown that acute otitis media caused by Streptococcus pneumoniae alters modeling dynamics in bone tissue structures surrounding the middle ear cavity. Initial resorption of bone is followed by formative activity, seen as massive osteoneogenesis. However, neither resorptive nor formative activity occurs in the otic capsule, supporting the existence of a perilymphatic zone of specialized bone. This study investigates adaptive bone modeling in acute otitis media caused by other bacteria frequently encountered in this disease. Seventy-five rats were inoculated with either non-typeable or type b Haemophilus influenzae, or Moraxella catarrhalis (25 rats in each group). Five rats from each group were sacrificed on days 4, 8, 16, 60 and 180 post-inoculation. Qualitative as well as quantitative histopathology revealed increasing apposition of new bone on both sides of the original bony wall of the middle ear bulla, i.e. at the inner and outer periosteum. Remodeling activity was seen on later days of sacrifice, as typical osteone (Haversian system) formation. Measured bone thickness in four anatomically well-defined localities progressed to a peak 2 months post-inoculation, followed by some degree of normalization. However, bone thickness was still massively increased 6 months after the acute incident. Except in the otic capsule, resorptive and formative activity was found in all bone tissue structures surrounding the middle ear cavity. These findings were irrespective of the type of inoculated bacteria. However, non-typeable or type b Haemophilus influenzae induces significantly more new bone formation than Moraxella catarrhalis. We conclude that acute otitis media caused by either of the bacteria is accompanied by massive and progressive net osteoneogenesis, already evident on day 4 and peaking 2 months post-inoculation, followed by some degree of normalization. Non-typeable and type b Haemophilus influenzae induce more new bone formation than Moraxella catarrhalis, whereas other features of bone histomorphology were equivalent. The present findings further support the existence of a perilymphatic zone of specialized bone.
