A prospective study of the natural history of acute hepatitis B was performed in 38 patients. Fatigue started median 4 weeks, abdominal symptoms median 3 weeks and signs of cholestasis median 2.5 weeks before peak SGPT values were reached. Extrahepatic manifestations occurred throughout the prodromal stage, the presence of arthropathy, urticaria or skin rashes was not related to the biochemical severity of liver disease. The higher the the maximal values of serum bilirubin and/or the older the patient, the longer the period of bilirubin elevation; a maximal bilirubin elevation less than 20 X the upper limit of normal was associated with normalisation of serum bilirubin within 6 weeks. No such correlations were found between the height of serum glutamic pyruvic transaminase, alkaline phosphatase, thymol turbidity and cholesterol levels and the subsequent duration of their abnormality. The elevation of alkaline phosphatase as well as the abdominal complaints might partly be caused by gastro-intestinal involvement. Immobilisation before peak SGPT was attained was associated with normalisation of serum glutamic pyruvic transaminase levels within 8 weeks after peak levels. 37 patients recovered completely. In one HBs-antigenemia and slight SGPT elevation persisted. Long term follow up was possible in 33 patients for 4 to 7 years, median 5 years.

Paraplegics whose range of motion is limited by para-osteo-arthropathy (POA) may have difficulty in becoming independent unless the heterotopic bone mass is removed. The recurrence rate is high if the bony mass is not mature at the time of surgery. Radiography and alkaline phosphatase correlations are not trustworthy. In 3 paraplegics with POA, radiolabeled osteotropic agents demonstrated a steady decrease in the uptake ratio (heterotopic/normal bone) followed by a steady-state plateau, reflecting the most useful index of maturation and allowing surgical removal of bone without recurrence.

During the period 1950-1985, a total of 179 cases of clinically overt hereditary haemochromatosis (HH) were registered in Denmark, 140 males and 39 females. Median age at diagnosis was 55 years (range 29-81). Diagnostic approaches, symptoms and physical signs at discovery are described. All patients had grade 3-4 liver haemosiderin iron, and cirrhosis was present in 84%. Serum (S-) transaminase was elevated in 92%, S-alkaline phosphatase in 47% and S-bilirubin in 23%, while plasma prothrombin time was below normal in 34%. Females had higher alkaline phosphatase than males (p less than 0.05). Bone marrow haemosiderin iron (n = 81) showed no relation to iron status indicators and was unsuitable as a diagnostic tool. Skin biopsy (n = 56) was positive for haemosiderin iron in 67% and for melanin in 57%, but was of limited value in the assessment of HH. Arthropathy was registered in 44%; arthralgias and clinical joint abnormalities occurred more frequently in females than in males (p less than 0.05). Latent diabetes mellitus was found in 34% and overt diabetes in 55%, being more frequent in males than in females (p less than 0.05). Other endocrine abnormalities were seen in 66%. Cardiac failure was observed in 9% and abnormal ECG in 35%. Males had higher haemoglobin (p less than 0.0001) and S-iron (p less than 0.01) than females, while S-transferrin, transferrin saturation, S-ferritin and mobilizable iron stores showed no significant sex differences. Median transferrin saturation was 87% (range 52-100); values greater than 62% were observed in 96% of the patients. Median S-ferritin was 3,400 micrograms/l (800-12,700) and median iron stores 14.8 g (4.5-36.4).

Synovial fluid samples of goat kids inoculated (ip) with 5 ml of 48 hr log phase culture of Mycoplasma mycoides sub sp. mycoides (large colony type) containing 10(7) cfu/ml were analysed for physical, cytological and biochemical properties. The synovial effusions were exudative in nature with increased volume. Gross appearances were serofibrinous, haemorrhagic and turbid containing flocculent materials with immediate clot formation. Mucinous precipitate quality was very poor having friable precipitates with cloudy supernatant. There were high total leucocytic and erythrocytic counts with significant high numbers of both neutrophils and lymphocytes. Synovial fluid sugar contents were significantly reduced, whereas total protein contents were significantly increased with concomitant reduction in albumin:globulin ratio. The alkaline phosphatase and transaminase values were also markedly increased in the synovial fluids of mycoplasma induced polyarthritic goat kids. The results may provide a clinical guideline for diagnosis, chemotherapy and prognosis of different joint diseases in domesticated animals.

Osteitis deformans is a focal disease of the osteoclasts characterised by increased bone resorption subsequently followed by increased bone formation leading to abnormal bone. A viral etiology seems increasingly probable, but remains unproven. 5-30% of the patients present with symptoms such as pain, deformity and fracture. Hearing loss, nerve- or root-compression, arthrosis and hyperuricaemia may complicate the disease while malignant degeneration, hypercalcemia and high output cardiac failure are rare. The diagnosis is based on X-ray findings but biopsy may be necessary in selected cases. The extent of the disease is revealed by bone scintigraphy and the activity of the disease reflected by urine hydroxyproline excretion and serum alkaline phosphatase.

Low calcium and magnesium levels were found in serum from women domiciled in an area where an osteo-arthrosis with a female preponderance is endemic. Despite decreased serum calcium, the methodology used indicated low circulating parathyroid hormone, while values for phosphorus, total alkaline phosphatase and the serum proteins were not remarkable. Alcoholism was excluded as a factor influencing the measured variables. The results reported, together with previous findings, justify intensified investigation into the link between diet-induced mineral deficiencies and endemic osteo-arthrosis at Mseleni.

To evaluate the effects of a long-term treatment with nandrolone decanoate on metabolism of the skeleton, a double-blind randomized study was carried out in women with joint diseases without metabolic bone derangement. Ten patients were treated with 50 mg of nandrolone decanoate every three weeks for two years; in six subjects a treatment with placebo was performed. As it concerns plasma calcium and phosphate, serum alkaline phosphatase, urinary excretion of calcium, phosphate, hydroxyproline and cAMP, as parathyroid index, it was not observed significant differences in the two examined groups. While in placebo group at the end of the study the intestinal radiocalcium remained unchanged and bone mineral content showed a slight decrease, on the contrary nandrolone decanoate treatment promoted a significant improvement in intestinal calcium absorption and an increase in bone mineral content.

Fifty-nine patients with end-stage renal disease undergoing long-term dialysis were studied prospectively for joint disease. Radiographic assessment allowed division of patients into 3 groups: group 1 included 12 patients with renal osteodystrophy and erosions of the metacarpophalangeal, proximal interphalangeal, distal interphalangeal, shoulder, wrist, and knee joints; group 2 had 11 patients with renal osteodystrophy without articular erosions; group 3 included 36 patients without osteodystrophy or erosions. Clinical manifestations were frequent in patients of group 1 and included episodes of arthralgias of the metacarpophalangeal, wrist, proximal interphalangeal, and knee joints. Patients of groups 1 and 2, particularly those of group 1, had a longer mean duration of dialysis and a higher mean serum alkaline phosphatase level compared with group 3 patients. The study indicates that there is a relatively high incidence (20%) of erosive arthropathy in dialysis patients. Renal osteodystrophy, more specifically, secondary hyperparathyroidism, and duration of dialysis are important factors in the development of this articular disorder.

Three sisters, each with chondrocalcinosis/arthropathy, are described who have the clinical, laboratory and pathologic findings characteristic of the adult form of hypophosphatasia. Premature loss of adult teeth, arthralgias and pain from bilateral femoral pseudo-fractures were associated with subnormal circulating alkaline phosphatase levels, phosphoethanolaminuria and osteomalacia diagnosed by iliac crest biopsy. Assay of alkaline phosphatase activity in the blood of kindred members revealed hypophosphatasemia in one of two younger brothers. Several subjects in subsequent generations also had suspiciously low alkaline phosphatase activity, but did not have histories of significant dental, bone or joint disease. Review of the medical records of the sisters' parents, aunts and uncles revealed normal alkaline phosphatase levels in their father and five of his siblings, but consistently low levels in their mother and two of her siblings. Despite hypophosphatasemia, the sisters' mother and her siblings lived to old age without clinical or radiographic evidence of bone disease. Our findings suggest that although adult hypophosphatasia can be transmitted as a dominant trait in some kindreds, there is considerable variation in the clinical expression of the biochemical defect. One person, generation or family may manifest clinical bone disease and arthropathy whereas the biochemical defect may be present but remain asymptomatic in others. Furthermore, in some cases, the adult form of hypophosphatasia may represent a developmental disorder with hypophosphatasemia appearing during adulthood.

Clinical observations suggest that the onset and severity of glucocorticoid (GC) induced osteoporosis is dependent on the duration of the GC treatment and the applied GC compound. To test whether these in vivo observations are reflected by different in vitro effects of various synthetic GCs on human bone cell metabolism we isolated human osteoblast-like cells (HOC) from bone biopsies of healthy (no clinical symptoms of arthritis or arthrosis) adults who underwent selective orthopedic surgery. HOC were identified as bone cells by 1,25-vitamin D3-stimulated increase of specific alkaline phosphatase (ALP) activity, secretion of osteocalcin and type-I procollagen peptide, and the ability to form mineral in vitro. We investigated the effects of dexamethasone (dexa), methylprednisolone (mpred), prednisolone (pred), and deflazacort (defla) on DNA-synthesis, ALP, and osteocalcin (OC)- and type-I procollagen peptide secretion of HOC in vitro. In summary, (1) GC exposure stimulates DNA synthesis after 6-12 hour treatment periods; (2) dex and mpred strongly inhibit DNA (48-hour treatment) and collagen synthesis but stimulate ALP, whereas pred and defla exhibit smaller effects on DNA synthesis, ALP, and collagen production; and (3) all tested glucocorticoids inhibit OC secretion by HOC in vitro. Thus, the effect of GC on DNA synthesis of HOC varies with the duration of GC exposure, and dex and mpred more potently affect HOC metabolism in vitro than pred and defla.
