Bilateral suprascapular nerve entrapment syndrome is very rare. It presents with shoulder pain, weakness and atrophy of the supraspinatus and infraspinatus muscles. We present a twenty-year old man having a history of bilateral shoulder pain associated with weakness. Electromyographic studies revealed signs of a lesion that caused a neupraxic state of the left suprascapular nerve, moderate axonal loss of the right suprascapular nerve and denervation of the right suprascapular muscle. The patient was treated with physical and medical therapy. Due to worsening of the symptoms, a surgical operation was performed by the excision of the transverse scapular ligaments bilaterally. His pain, weakness and atrophy had diminished on examination six weeks later. Suprascapular nerve entrapment should be considered in patients with shoulder pain, particularly those with weakness and atrophy of the supraspinatus and infraspinatus muscles.

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.

Glomerulonephritis and pulmonary hemorrhage are features of Goodpasture's syndrome. Goodpasture's syndrome accompanied with central nervous system (CNS) vasculitis is extremely rare. Herein, we report a rare case of CNS vasculitis associated with Goodpasture's syndrome in a 34-year-old man, who presented with a seizure and sudden onset of right sided weakness. He also had recurrent hemoptysis of one month's duration. Goodpasture's syndrome is histologically diagnosed by intense linear deposits of IgG along the glomerular basement membrane in both renal and lung tissues.

OBJECTIVETo explore the clinical and laboratory features and the prognosis of juvenile dermatomyositis (JDM) complicated with interstitial lung disease (ILD).

METHODData of 39 cases of JDM complicated with ILD hospitalized in Beijing Children's Hospital from January 2005 to December 2011 were collected. The clinical features, laboratory data and prognosis of these children were analyzed.

RESULTOf the 39 cases studied, 16 were boys, and 23 girls. The average age of onset was 5.6 years, and 61.5% of the patients' age of onset (24 cases) was under 6 years. Rashes (17 cases, 43.6%), simultaneous eruption of rashes and muscle weakness (14 cases, 35.9%), fever (4 cases, 10.1%), or muscle weakness (3 cases, 7.7%) were common initial symptoms of the disease. Only 51.3% of the patients (20 cases) had the symptoms of respiratory system, but (24 cases) 61.5% were complicated with that of the gastrointestinal system; (27 cases) 69.2% had at the same time electrocardiographic and echocardiographic abnormalities. The chest high resolution computed tomography (HRCT) showed cord or band-like shadows in their lungs of more than half of the cases (25 cases, 64.1%), and other changes included ground glass-like shadow (10 cases, 25.6%), net and lineation-like shadow (9 cases, 23.1%), nodular change (5 cases, 12.8%). The patients complicated with lung essential infiltration accounted for as high as 71.8% (28 cases). These imaging changes were largely seen on both dorsal sides of their lungs. Severe patients also had mediastinal emphysema, pneumothorax, pneumorrhagia or aerodermectasia. Twenty-four patients underwent pulmonary function examination, and 62.5% of the patients' pulmonary function (15 cases) was abnormal. The fatality rate of the cases studied was 10.1%.

CONCLUSIONThe imaging changes of patients suffering from JDM with ILD were often more severe as compared to the clinical symptoms, and were often complicated with damages to other systems and organs. The prognosis of those patients was poorer than others. Patients with JDM especially at a younger age of onset and with various organ damages should be examined with chest HRCT examinations as early as possible.

OBJECTIVETo analyze and summarize the characteristics of glycogen storage disease type II (Pompe disease) patients according to the clinical description and prognosis.

METHODSeventeen Chinese patients diagnosed by acid alpha-glucosidase (GAA) enzyme activity test were reviewed. Clinical data tables were designed. Interviews were made via phone calls. Information was collected to reach the objective.

RESULTFour of 17 patients diagnosed by acid alpha-glucosidase are infantile-onset, symptoms started between 2 to 6 months after birth with increased serum creatine kinase and cardiac problems, with or without respiratory concerns. Other 13 patients were later-onset cases, and their symptoms started between 2 to 22 years of age with increased serum creatine kinase. Eleven later-onset patients started with muscle weakness, 2 patients developed respiratory insufficiency, 2 patients showed scoliosis, and 1 patient expressed increased serum creatine kinase with abnormal liver function. Just 3 of the later-onset patients were treated with mechanical ventilator and adjuvant therapy, others were not. All patients' acid alpha-glucosidase (GAA) enzyme activity analysis showed lower than 10% of normal. Fourteen patients were tested by muscle biopsy pathology, and 9 of them progressed to glycogen storage disease type II; 10 patients received genetic analysis, and 6 of them had two mutations which cause the disorder. Twelve of the 17 patients were interviewed successfully. In 3 of the infant-onset patients the disease resulted in death from respiratory failure, and 1 is still alive at the age of 1 year and 7 months. In 4 of 8 later-onset patients the disease resulted in death from respiratory failure between 3 to 5 years after onset of symptoms. Three of 4 survivors had increased muscle weakness, and 1 patient kept alive with ventilator without any changes. Seven of 12 interviewed patients died, the mortality rate was 58.3%.

CONCLUSIONGlycogen storage disease type II (Pompe disease) present differently in the clinic. Infant-onset Pompe disease is mainly characterized by generalized muscle weakness and obvious cardiac involvement. It's a dangerous disease, with high mortality rate. Later-onset Pompe disease is characterized by chronic proximal muscle weakness and respiratory insufficiency. GAA enzyme activity analysis, muscle biopsy and genetic analysis used to support the diagnosis of Pompe disease. Prognosis of the disease depends on age of onset and respiratory muscle involvement.
