The development of erythrocyte alloantibodies complicates transfusion therapy in patients with thalassemia. However, no data are available on the frequency of erythrocyte alloimmunization in patients with transfusion-dependent thalassemia in Taiwan. We analysed the clinical and transfusion records of 30 individuals (15 females and 15 males; mean age, 20 years; range, 4-31 years) with thalassemia who had regular transfusions for periods ranging from 0.5 to 20 years. Of the 30 patients, 28 who had beta-thalassemia major and two who had Hb H disease (alpha thalassemia), 11 (37%) were found to carry alloantibodies. All alloantibodies were clinically significant specificities, including four cases of anti-E, two of anti-E + c, two of anti-'Mi(a)', one of anti-'Mi(a)' + E, one of anti-D and one of anti-S. Alloimmunization to erythrocyte antigens is a frequent complication in transfusion-dependent thalassemia.

Fracture liaison services (FLS), implemented in different ways and countries, are reported to be a cost-effective or even a cost-saving secondary fracture prevention strategy. This presumed favorable cost-benefit relationship is encouraging and lends support to expanded implementation of FLS per International Osteoporosis Foundation Best Practice Standards. This study summarizes the economic impact and cost-effectiveness of FLS implemented to reduce subsequent fractures in individuals with osteoporosis. This systematic review identified studies reporting economic outcomes for FLS in osteoporotic patients aged 50 and older through a comprehensive search of MEDLINE, EMBASE, Cochrane Central, and PubMed of studies published January, 2000 to December, 2016. Grey literature (e.g., Google scholar, conference abstracts/posters) were also hand searched through February 2017. Two independent reviewers screened titles and abstracts and conducted full-text review on qualified articles. All disagreements were resolved by discussion between reviewers to reach consensus or by a third reviewer. In total, 23 qualified studies that evaluated the economic aspects of FLS were included: 16 cost-effectiveness studies, 2 cost-benefit analyses, and 5 studies of cost savings. Patient populations varied (prior fragility fracture, non-vertebral fracture, hip fracture, wrist fracture), and FLS strategies ranged from mail-based interventions to comprehensive nurse/physician-coordinated programs. Cost-effectiveness studies were conducted in Canada, Australia, USA, UK, Japan, Taiwan, and Sweden. FLS was cost-effective in comparisons with usual care or no treatment, regardless of the program intensity or the country in which the FLS was implemented (cost/QALY from $3023-$28,800 US dollars (USD) in Japan to $14,513-$112,877 USD in USA. Several studies documented cost savings. FLS, implemented in different ways and countries, are reported to be cost-effective or even cost-saving. This presumed favorable cost-benefit relationship is encouraging and lends support to expanded implementation of FLS per International Osteoporosis Foundation Best Practice Standards.

A 25-year-old woman underwent surgical tooth extraction. Several hours after the procedure, the woman complained of severe retrosternal pain and mild dyspnea. Subsequent imaging revealed subcutaneous emphysema from the mandibular region extending to the mediastinum and left side pneumothorax, as well as pneumopericardium. After treatment with antibiotics and analgesics, the patient recovered without any complications.
