Forty intertransverse process spinal fusions were performed across two to three vertebrae in four cases of fracture-dislocations of the dorsolumbar region and 36 cases of degenerative joint and disk disease, including spinal stenosis and spondylolisthesis of lumbosacral segments. In all cases, arthrodesis was performed with a composite of AAA cortical bone strips and local autologous spongiosa, including lamellar bone chips. The iliac crest was not used as a donor site in any case. The apophyseal joints were erased, packed with autologous bone slivers, and transfixed with AAA bone pegs. In selected cases, AAA cortical bone "H-blocks" were also placed between the spinous process as in a routine posterior lateral arthrodesis. In cases of bilateral total laminectomy for fractures or spinal stenosis, the excised cancellous bone chips were cleaned of soft parts and transplanted across the transverse processes beneath and around the AAA cortical bone implants. In the above-described operations, graded by the Anatomic-Functional Economic (AEF) system, the long-term excellent and good results were: 4/4 in fracture dislocations; 23/28 in degenerative arthritis and spinal stenosis; 5/8 in spondylolisthesis. Overall, there were over 80% excellent and good results; the pseudarthrosis rate was 12%. In a comparable surgical procedure with autologous iliac bone in 58 control cases, reported in the foregoing article in this volume, the minimum pseudarthrosis rate was 8%. Raw band bone, either frozen or freeze-dried, is now either so infrequently considered or unavailable for lumbar spinal operations or unavailable for lumbar spinal operations that further investigations of AAA bone grafts are warranted in a statistically significant number of patients. Although autologous bone is the ideal bone for a graft, the most important incentive for further investigations of AAA bone is the avoidance of complications of excision of massive bone grafts from iliac crests.

This case is an example of an unsuspected abdominal aortic aneurysm. The patient's symptoms and the history obtained were suggestive of osteoarthritis. The patient sought medical attention for low-back pain through a compensation and pension exam.

The effect of active absorbable algal calcium (AAA Ca) with collagen and other matrix components on aging-associated skin changes and backache and joint pain was tested in a case-controlled study of 40 test subjects and 40 age-matched control subjects (mean age, 65 years) complaining of backache and knee joint pain due to osteoarthritis, spondylosis deformans, and/or osteoporosis. Supplementation with 900 mg calcium (given as AAA Ca) and 3.5 g collagen and other matrix components, including glucosamine, daily for 4 months resulted in a marked alleviation of subjective pain, assessed by the face scale. A fall of skin impedance in response to exercise loads, such as standing up, walking, squatting, and climbing up and down stairs, reported as an objective manifestion of pain, was also alleviated. The basal skin impedance, which increases with age, was significantly reduced in response to the Ca-collagen-matrix supplementation, suggesting a change of skin properties similar to rejuvenation, along with subjective smoothening and moistening of the skin. Urinary excretion of N-terminal crosslinking telopeptide of type I collagen (NTx) was decreased in the Ca-collagen-matrix supplementation group, but not in the control group. In addition to calcium suppression of parathyroid hormone, preventing bone resorption, collagen, acting on the intestinal lymphatic system, may protect collagen from degradation through the inhibition of cytokine-induced release of metalloproteinases, including collagenase.

Treatment options for crescentic glomerulonephritis include the use of steroids, cytotoxic therapy, and, in severe cases, intravenous immunoglobulins and plasmapheresis. Injury and lysis of capillary glomerular basement membrane, which is made up of type IV collagen, laminin, fibronectin, and proteoglycans, by serine proteinases and matrix metalloproteinases (MMPs) likely is an important participant in the pathogenesis of crescentic glomerulonephritis. Tetracycline derivatives inhibit not only the activity of MMPs, but also their production, and have been investigated for the treatment of disorders in which the MMP system becomes amplified, such as degenerative osteoarthritis, periodontitis, cancer, and abdominal aortic aneurysm. We report an interesting case of crescentic glomerulonephritis in a young man who was treated with cyclophosphamide and prednisone. The patient developed steroid-induced acne that was treated with long-term oral doxycycline therapy. During the period the patient was administered doxycycline, proteinuria decreased by 70% and recurred when doxycycline was stopped. To our knowledge, this is the first report of possible benefits of a metalloproteinase inhibitor (doxycycline) in glomerulonephritis in humans. Future studies are urgently required to explore the option of metalloproteinase inhibitors in the treatment of proliferative glomerulonephritis.

Active Absorbable Algal Calcium (AAA Ca) is made by submaximally (800 degrees ) heating cleaned oyster shell under reduced pressure and mixing it with similarly heated seaweed (Cystophyllum fusiforme). AAA Ca, the best absorbed from the intestine than other available calcium compounds, consequently most efficiently suppresses parathyroid hormone secretion, increases bone mineral density and decreases vertebral fracture. Aging is associated with calcium deficiency, mostly because of the decreased biosynthesis of 1,25 (OH)2 vitamin D in the kidney. Parathyroid hormone consequently increases, contributing to various diseases associated with aging such as osteoporosis or decrease of calcium in the bone, as well as hypertension, arteriosclerosis, Alzheimer's disease and osteoarthritis due to paradoxical increase of calcium in vascular walls, brain, cartilage and intracellular compartment of many kinds of cells. Mild calcium deficiency is hard to detect despite these serious consequences because of the remarkable constancy of blood calcium concentration maintained by elaborate homeostatic control. Only by successfully counteracting calcium deficiency by AAA Ca with outstanding absorbability, the phenomenon of calcium paradox becomes a recognizable reality within our reach.

Fusion of the ankle is an established option for end-stage degenerative joint disease. The purpose of this paper is to present the surgical technique as well as our own results. AAA starts with removal of all the remaining cartilage and joint detritus. For this we routinely use a posterolateral portal. When opening the subchondral plate one must be careful not to remove too much bone. In our hands a small chisel is very helpful for this step. Fixation is performed with two screws. In 31 out of 35 patients, we were able to obtain a solid bony fusion. AAA of the ankle can be performed in patients without significant malalignment or bony defect. It is an "in-situ" fixation of the destroyed painful joint, which is not suitable for patients with neuropathic joints. Patients with secondary joint destruction due to rheumatoid arthritis can also be treated with AAA.

Heterozygous mutations in the SMAD3 gene were recently described as the cause of a form of non-syndromic familial aortic thoracic aneurysm and dissection (FTAAD) transmitted as an autosomal dominant disorder and often associated with early-onset osteoarthritis. This new clinical entity, called aneurysms-osteoarthritis syndrome (AOS) or Loeys-Dietz syndrome 3 (LDS3), is characterized by aggressive arterial damages such as aneurysms, dissections and tortuosity throughout the arterial tree. We report, here, the case of a 45 year-old man presenting multiple visceral arteries and abdominal aortic aneurysms but without dissection of the thoracic aorta and without any sign of osteoarthritis. Exome-sequencing revealed a new frameshift heterozygous c.455delC (p.Pro152Hisfs*34) mutation in the SMAD3 gene. This deletion is located in the exon 3 coding for the linker region of the protein and causes a premature stop codon at positions 556-558 in the exon 4. The same mutation was found in the proband's mother and sister who had open surgery for abdominal aortic aneurysm and in one of his children who was 5 year-old and did not present aneurysm yet.
