Any medical diagnosis should take a multimodal approach, especially those involving tumour-like conditions, as entities that mimic neoplasms have overlapping features and may present detrimental outcomes if they are underdiagnosed. These case reports present diagnostic pitfalls resulting from overdependence on a single diagnostic parameter for three musculoskeletal neoplasm mimics: brown tumour (BT) that was mistaken for giant cell tumour (GCT), methicillin-resistant Staphylococcus aureus osteomyelitis mistaken for osteosarcoma and a pseudoaneurysm mistaken for a soft tissue sarcoma. Literature reviews revealed five reports of BT simulating GCT, four reports of osteomyelitis mimicking osteosarcoma and five reports of a pseudoaneurysm imitating a soft tissue sarcoma. Our findings highlight the therapeutic dilemmas that arise with musculoskeletal mimics, as well as the importance of thorough investigation to distinguish mimickers from true neoplasms.

Vitamin D deficiency is common and may contribute to osteopenia, osteoporosis and falls risk in the elderly. Screening for vitamin D deficiency is important in high-risk patients, especially for patients who suffered minimal trauma fractures. Vitamin D deficiency should be treated according to the severity of the deficiency. In high-risk adults, follow-up serum 25-hydroxyvitamin D concentration should be measured 3-4 months after initiating maintenance therapy to confirm that the target level has been achieved. All patients should maintain a calcium intake of at least 1,000 mg for women aged ≤ 50 years and men ≤ 70 years, and 1,300 mg for women > 50 years and men > 70 years.

OBJECTIVETo evaluate the efficacy and safety of alendronate for the treatment of osteoporosis/osteopenia secondary to hyperthyroidism.
METHODSFrom April 2008 to November 2009, 27 patients with hyperthyroidism with osteoporosis/ osteopenia measured by dual energy X-ray absorptiometry (DXA) were included in this study, and then they were randomly divided into two groups (group A and group B) by simple random sampling. Group A consisted of 14 patients treated with antithyroid drug and caltrate D, the antithyroid drug change with thyroid function, and caltrate D 600 mg per day. Group B consisted of 13 patients treated with antithyroid drug, caltrate D and alendronate, antithyroid drug and caltrate D the same as group A, and alendronate 70 mg weekly. Meanwhile, 21 healthy voluntary adults were chosen as control group. And compared with the control group which was treated with nothing. Followed-up for one year, the bone mineral density (including T-score, Z-score, BMD) in lumbar spine (LS), femoral neck (FN) and distal radius (DR) and general information, were compared before and after treatment.
RESULTSBMD at FN and DR were significantly higher at 12 months after treatment than at the baseline in group A (P = 0.000); T-score, Z-score, and BMD at the LS, FN and DR were all significantly higher at 12 months after treatment than at the baseline in group B (P < 0.05), but these data could not arrive to normal level. In group A, the percentage increased in BMD at the LS, FN, and DR were (4.34 +/- 10.5)%, (3.21 +/- 1.38)%, (1.95 +/- 0.44)%, respectively, at 12 months after treatment. In group B, the percentage increased in BMD at the LS, FN, and DR were (6.10 +/- 8.12)%, (4.10 +/- 5.64)%, (3.10 +/- 3.23)%, respectively, at 12 months after treatment. There was significant difference in the rate of increase between two groups (P < 0.05). AKP decreased, weight, BMI increased, and thyroid function decreased, after treatment than those before in both of the two groups. (P < 0.05).
CONCLUSIONAlendronate can significantly increase BMD in treating patients with hyperthyroidism and osteoporosis/osteopenia. Compared with anti-thyroid drugs alone, treatment with alendronate can obtain more clinical effect and also very safety.

INTRODUCTIONThe number of patients suffering from chronic kidney disease (CKD) is increasing worldwide. Hyperphosphataemia and high serum calcium (Ca) and phosphorus (P) product contribute to the substantial increase in cardiovascular events in CKD patients. Although reports of CKD complications in Iranian haemodialysis (HD) patients are comparable to data from other developed countries, management of these complications has failed to meet generally accepted targets. This study evaluated the impact of clinical pharmacy services in the management of complications in HD patients.
METHODSDuring a six-month prospective study, clinical pharmacists conducted medical visits in the HD ward and adjusted the patients' medications according to their laboratory findings.
RESULTSSerum Ca concentration was increased in hypocalcaemia patients and decreased in hypercalcaemia patients until it reached the optimal range in both groups. A decline in serum P level was noted in hyperphosphataemia patients, although it did not reach the target range. The Ca × P product decreased in patients with Ca × P > 55 mg2/dL2. Although it did not reach the goal, there was an increase and decrease in serum intact parathyroid hormone (iPTH) concentration in suboptimal and supraoptimal range patients, respectively. Serum Ca, P and iPTH levels did not change in patients with optimal values at the initiation of the study. Haemoglobin concentration increased in anaemic patients and serum ferritin reached target values in all patients. Total cholesterol, low-density lipoprotein cholesterol and triglycerides decreased to near-optimal values in dyslipidaemia patients.
CONCLUSIONThis study showed that clinical pharmacy services at the HD centre can improve the management of complications in CKD patients.

Adefovir dipivoxil is commonly used for treatment of chronic hepatitis B. The renal toxicity of adefovir dipivoxil is dose- and time-related, occurring often in patients with a daily dose over 30 mg and those with impaired renal function. We report a case of chronic hepatitis B with a history of taking adefovir dipivoxil at 10 mg/day for 4 years. The patient complained of lumbosacral and joint pain and had the diagnosis of ankylosing spondylitis (AS) or spondyloarthropathy in several hospitals before admission in our hospital. A diagnosis of acquired Fanconi syndrome and hypophosphatemia osteomalacia associated with progressive muscular weakness was made eventually. We reviewed the literature and found reports of only fewer than 10 similar cases. Clinical attention should be given to kidney damage induced by adefovir dipivoxil.

Scurvy is very rare disease in industrialized societies. Nevertheless, it still exists in higher risk groups including economically disadvantaged populations with poor nutrition, such as the elderly and chronic alcoholics. The incidence of scurvy in the pediatric population is very low. This study reports a case of scurvy in a 5-year-old girl with cerebral palsy and developmental delay based on MRI findings.

Vitamin K is the cofactor for the hepatic carboxylation of glutamic acid residues in a number of proteins including the procoagulants factors ll, Vll, lX, and X. The role of vitamin K in normal bone function is not fully understood. Inherited deficiency of vitamin K dependent coagulation factors is a rare bleeding disorder reported only in a few patients. Here we present an 18-month old child who presented with osteopeni due to inherited vitamin K deficiency. While the patient had high bone specific alkaline phosphatase and parathyroid hormone levels and low osteocalcin and bone mineral density values, with the regular supplementation of vitamin K all the mentioned parameters returned to normal values.
