The clinical features, investigation and outcome in 24 patients with pregnancy-associated osteoporosis, followed for up to 24 years from the first pregnancy are described. Symptoms occurred most often in the first pregnancy (17 patients) at a mean age of 27 years (range 21-36); the most frequent was back pain in late pregnancy or post partum (n = 18); less common was hip (n = 5) or ankle (n = 1) pain. In most, symptoms improved soon after delivery. Four subjects had pre-existing disorders known to reduce bone density (corticosteroid therapy, heparin treatment, mild osteogenesis imperfecta and previous anorexia nervosa). Radiographs showed vertebral collapse or localized osteoporosis of the hip, with MRI evidence of oedema. Forearm bone mineral density (BMD) was sometimes normal, but spinal BMD (measured by DXA) was low. Bone biopsies in eleven patients showed features compatible with osteoblast failure. Except for the patient with mild osteogenesis imperfecta, cultured dermal fibroblasts synthesized and exported normal Type I collagen. In 14 subsequent pregnancies (10 patients) there was no recurrence in ten and mild symptoms in the remainder. Excluding one patient who had repeated osteoporotic fractures and vertebral collapse, the long-term prognosis was good.

Should rheumatologists provide an acute referral service for general practitioners (GPs) and other clinical units? Is it cost effective? We prospectively studied acute referrals to one unit over 10 months, recording their source, diagnosis, management and outcome. Current rheumatology patients and cases only needing telephone advice were excluded. There were 253 referrals: 82 from GPs, nine from Accident and Emergency, and 162 from other hospital units. Their diagnoses comprised connective tissue diseases (22), back pain (46), inflammatory arthritis (59), osteoarthritis (22), paediatric cases (11), soft tissue problems (41) and 52 other disorders. Thirty-two needed active treatment within 24 h (classified as emergencies); examples included cerebral lupus, vasculitic pulmonary haemorrhage, retroperitoneal lymphoma with sacral plexus compression, temporal arteritis with reduced visual acuity and acute monoarthritis. All needed immediate therapy; only one died. Most (176 cases) were less urgent and needed advice in 48 h. Examples included osteoporotic vertebral collapse and acute rheumatoid disease. Forty-five could have been seen routinely; examples included lateral epicondylitis and adhesive capsulitis. The service required 1 day per week of medical staff time at an average cost of 45 pounds per case. We concluded that an acute rheumatology service is needed; it can be provided within the working day and is cost effective.

Two box jellyfish in particular cause problems in tropical Queensland waters. Chironex fleckeri inhabit calm waters close to the shore between November and May. The venom includes three major components: haemolytic dermatonecrotic and myocardial. The dermatonecrotic toxin causes a ladder pattern of whiplash lesions to the skin which ulcerate become necrotic and heal very slowly over months: Neuromuscular paralysis and cardiovascular collapse may be fatal within minutes of envenomation. Emergency treatment comprises inactivation of stinging capsules by vinegar removal of tentacles analgesia, cardiopulmonary resuscitation and the administration of the specific antivenom. Carukia barnesi ('Irukandji') are found in both coastal and open waters. A patch of erythema with papules at the sting site is characteristically followed 30 min later by the onset of a catecholamine mediated syndrome. Headache and severe abdominal and back pain are usual and may be followed by hypertension, tachyarrhythmias and cardiogenic shock.

Cushing's syndrome in pediatric patients has been rarely reported and most of the cases are due to adrenal tumors. When the etiology is an ACTH-secreting pituitary adenoma, most often it is a microadenoma. We report on a 9 year-old girl with an ACTH-secreting macroadenoma, whose surgical removal through transsphenoidal approach was extremely difficult due to invasion of the cavernous sinus as well as adjacent structures. After two surgical approaches and stereotactic radiotherapy, she still suffers from the deleterious effects of hypercortisolism, especially marked osteoporosis with vertebral collapse, which interferes with her walking and causes excruciating pain. Two months after the radiotherapy, we still had doubts about the prognosis regarding the persistence of the hypercortisolism. From six months on, her general health started improving, she lost weight, the backache disappeared and her cortisol level returned to normal.

Vertebral body collapse and back pain are an unusual presentation for childhood leukemia. This report is intended to promote greater awareness that acute lymphocytic leukemia can cause significant back pain in children without other systemic symptoms. We describe four cases in which patients with acute lymphocytic leukemia presented with back pain and vertebral compression fractures. All of the patients were initially misdiagnosed. No patient had neurologic compromise, despite extensive vertebral body collapse. The back pain was relieved after chemotherapy.

Acute lymphatic leukemia presenting with bone pain and spine involvement is a recognized clinicopathologic complex that can mimic a wide range of orthopaedic conditions. Bone pain as the presenting complaint is common, with a reported incidence of 27% to 50%. Radiologic abnormalities associated with leukemia in children has been described previously. In the literature, the incidence of spinal involvement is controversial, but there is agreement that the spine is less commonly involved than are the long bones. At the onset of the disease, only 10% of children have normal peripheral blood counts. If the patient has spinal involvement and a normal leukocyte count, the diagnosis is often unclear. Only three of these patients have been described in the literature; this article adds one more patient with acute lymphatic leukemia with back pain as the main symptom, vertebral collapse, and a normal peripheral blood cell count at the time of initial presentation. It illustrates that delay in diagnosis frequently occurs, with the classic features of the disease being uniformly absent.

Osteoporosis in pregnancy is a rare clinical problem of unknown cause. If the bone loss results from the pregnancy alone it should improve toward normal after delivery; in contrast, where bone density was low before pregnancy, due to some other secondary cause, significant postpartum improvement might not be expected. Thirteen women (age 23-37 years) with pregnancy-associated osteoporosis presenting with either pain in the back and vertebral collapse (8 subjects) or pain in the hip (5 subjects) had consecutive dual-energy X-ray absorptiometry measurements of bone mineral density (BMD) for up to 8 years after an affected pregnancy. The BMD results were expressed as a Z-score in relation to an age-matched mean. The mean initial (0-6 months postpartum) BMD was low in both groups and at both sites. In the back pain group the mean spine Z-score (Ll-L4) was -3.34 (range -2.25 to -4.66) and mean total hip Z-score was -2.41 (range -1.44 to -3.82). In the hip pain group the mean spine Z-score was -2.00 (range -1.48 to -2.65) and mean hip Z-score was -2.19 (range -1.12 to -3.26). Subsequent mean hip and spine BMD increased significantly toward the lower end of the normal range. We conclude that a reversible part of the bone loss is related to the pregnancy itself. A low BMD before pregnancy cannot be excluded. Knowledge that the bone density increases after an affected pregnancy, combined with the known rarity of recurrent symptoms in subsequent pregnancies, is important in prognosis.

The death of a 36-year-old alcoholic man who died after developing seizure activity while being treated with tramadol, as well as with venlafaxine, trazodone, and quetiapine, all of which interact with the neurotransmitter serotonin, is reported. The decedent, who had a history of chronic back pain, alcoholism, depression, mild hypertensive cardiovascular disease, and gastritis, had just been discharged from the hospital after 4 days of alcohol detoxification treatment. During the admission, no withdrawal seizures were noted. The morning after discharge, a witness observed the decedent exhibiting seizure activity and then collapsing. An autopsy was performed approximately 6 hours after death, and the anatomic findings were consistent with seizure activity and collapse, which included biting injuries of the tongue and soft-tissue injuries of the face. Toxicologic analysis identified tramadol, venlafaxine, promethazine, and acetaminophen in the urine; tramadol (0.70 mg/L) and venlafaxine (0.30 mg/L) in the heart blood, and 0.10 mg of tramadol in 40 ml of submitted stomach contents. No metabolites, such as acetate, acetone, lactate, and pyruvate, were found in the specimens that would be characteristically found in a person with alcohol withdrawal syndrome. The threshold for seizures is lowered by tramadol. In addition, the risk for seizure is enhanced by the concomitant use of tramadol with selective serotonin reuptake inhibitors or neuroleptics, and its use in patients with a recognized risk for seizures, i.e., alcohol withdrawal. The cause of death in this individual was seizure activity complicating therapy for back pain, depression, and alcohol withdrawal syndrome. The data in Adverse Event Reporting System of the Food and Drug Administration from November 1, 1997 to September 8, 1999 was reviewed along with a MEDLINE search from 1966 to the present. This case appears to be the first reported death caused by seizure activity in a patient taking tramadol in combination with drugs that affect serotonin.

The aims of the current study were to evaluate the long-term clinical and radiologic results of anterior lumbar interbody fusion (ALIF) for isthmic spondylolisthesis. Between 1981 and 1988, a total of 35 patients underwent ALIF for isthmic spondylolisthesis. Of these, 23 patients were followed clinically and radiographically for more than 10 years (average, 13.3 years). The Japanese Orthopaedic Association low-back pain score was used to evaluate the outcome of subjective symptoms and clinical signs. The preoperative and postoperative percentage of slip, preoperative and postoperative intervertebral disk height, interbody graft union, and pars defect union were evaluated by serial radiographs. The adjacent disk degeneration was also evaluated by radiographs and magnetic resonance imaging. Although the low-back pain score worsened after 5 years, ALIF provides satisfactory overall long-term clinical results. The preoperative percentage of slip and the disk height were corrected after surgery, but at the time of interbody graft union, slip and disk height recurred as a result of grafted bone collapse. The rate of union in the grafted area was 83%. In the nonunion cases, the scores gradually deteriorated with time, but the overall results were not different from those of union cases. Radiographs showed adjacent disk degeneration in 52% of cases in the upper adjacent level and in 70% of cases in the lower adjacent level, but these changes were not correlated with clinical outcomes.

Carney complex is an extremely rare, autosomal dominant, multi-system disorder characterized by multiple neoplasias and lentiginosis. The genetic defect responsible for this complex has been localized to the short arm of chromosome 2 (2p16). The most prevalent clinical manifestations in patients with Carney complex are spotty skin pigmentation, skin and cardiac myxomas, Cushing's syndrome and acromegaly. Here we report the case of a 31-year-old woman with a spontaneous pregnancy. At 32 weeks of gestation, she was admitted to our Department of Obstetrics with hypertension and severe back pain. In addition, she had unusual pigmentation and typical cushingoid features. One day after admission, the pregnancy was terminated by emergency cesarian section because of preeclampsia and pathological CTG. During the postoperative period the severe back pain persisted, and radiographic evaluation revealed a collapse of L(2)/L(3) with severe osteopenia. A CT scan showed a mass in the right suprarenal area. Histopathological examination revealed a primary pigmented nodular adrenocortical disease. After biochemical confirmation of the diagnosis of Cushing's syndrome, it was recognized that the patient met the diagnostic criteria for Carney complex.
