Treatment of myofascial trigger points in common shoulder disorders by physical therapy: A randomized controlled trial [ISRCTN75722066]

Background  

Shoulder disorders are a common health problem in western societies. Several treatment protocols have been developed for the clinical management of persons with shoulder pain. However available evidence does not support any protocol as being superior over others. Systematic reviews provide some evidence that certain physical therapy interventions (i.e. supervised exercises and mobilisation) are effective in particular shoulder disorders (i.e. rotator cuff disorders, mixed shoulder disorders and adhesive capsulitis), but there is an ongoing need for high quality trials of physical therapy interventions. Usually, physical therapy consists of active exercises intended to strengthen the shoulder muscles as stabilizers of the glenohumeral joint or perform mobilisations to improve restricted mobility of the glenohumeral or adjacent joints (shoulder girdle). It is generally accepted that a-traumatic shoulder problems are the result of impingement of the subacromial structures, such as the bursa or rotator cuff tendons. Myofascial trigger points (MTrPs) in shoulder muscles may also lead to a complex of symptoms that are often seen in patients diagnosed with subacromial impingement or rotator cuff tendinopathy. Little is known about the treatment of MTrPs in patients with shoulder disorders.     

原发性胆汁性肝硬化伴系统性硬化症的临床特点与预后

背景与目的：原发性胆汁性肝硬化（PBC）伴系统性硬化症（SSc）的预后仍不十分清楚，该研究拟对其临床特点及预后进行评估。方法：从一个含580例患者的PBC数据库中选出43例PBC伴SSc患者，同时为每例PBC—SSc患者匹配2例单纯PBC患者作为对照，监测初次就医时的血清胆红素浓度。结果：局限皮肤型SSc者40例（93％）。诊断PBC时的中位年龄为49．7岁，胆红素浓度为17μmol／L，白蛋白水平为40．5g／L。24例（56％）患者于SSc后在中值为4．9年发生PBC。配对患者诊断PBC时的中位年龄为53．2岁、胆红素浓度为12μmol／L、白蛋白水平为41g／L。两组患者中位随访时间相似：PBC—SSc组为3．16年，单纯PBC组为4．8年。PBC—SSc患者南于较少接受移植手术（HR0．068；P：0．006），在校正性别、年龄、胆红素对数及碱性磷酸酶等因素后，其移植术或死亡风险（HR0．116；P=0．01）均明显降低，同时胆红素上升的比例亦较低（P=0．04）。     

Predominance of staphylococcal organisms in infections occurring in a burns intensive care unit.

To assess the sites, incidence, and bacteriology of infections in intensive care burn patients, a prospective survey of all admissions to a tertiary care institution burn unit was carried out over a 12-month period. One hundred and sixteen patients were admitted, 106 with a diagnosis of thermal burns. Forty patients developed 90 infections. Only two deaths occurred, one in a patient with sepsis. In order of frequency, pneumonia, burn infection, UTI and primary bacteraemia were most common. Staphylococcal species accounted for a majority of infections at all body sites except UTI (47 per cent of all infections, including 11 of 14 bacteraemic infections). Staph. aureus sepsis was more common in those carrying the organism on admission. Strain typing of paired admission and subsequent clinical isolates in 19 patients with Staph. aureus sepsis indicated that eight (42 per cent) became infected with a strain they carried on admission. Further reductions in septic complications of burns in our center would be best directed at staphylococcal species, particularly Staph. aureus. Both eradication of carrier state, and prevention of acquisition of Staph. aureus strains could be explored.     

Asynchronous blepharospasm, facial and cervical dystonia, and bilateral asynchronous hemifacial spasm.

We present a patient with a facial movement disorder that has characteristics of both blepharospasm and bilateral asynchronous hemifacial spasm. Because of the increased incidence of blepharospasm in patients with hemifacial spasm, our patient's clinical presentation is probably not a chance occurrence, but rather a manifestation of some predisposition for these two movement disorders. This unusual constellation of signs and symptoms challenges the current diagnostic criteria and suggests that some of these facial movement disorders may lie on a spectrum, rather than represent distinct entities.
