Acute exacerbation of idiopathic pulmonary fibrosis (AE-IPF) is defined as an acute and clinically significant respiratory deterioration characterized by evidence of new, widespread alveolar abnormality. In the past, AE-IPF was considered to be idiopathic, which was hard to be prevented and its prognosis was hard to be obviously improved; the latest researches have shown that AE-IPF can be triggered by known causes, including pulmonary infection, aspiration, etc. This review summarizes the etiology or risk factors, treatment and prevention of AE-IPF according to the latest researches.
Objective To improve the awareness of acute exacerbation of idiopathic pulmonary fibrosis ( AEIPF) and discuss its clinical characteristics, diagnosis, treatment and outcome. Methods The clinical data of patients with AEIPF from June 2006 to June 2011 in 11 hospitals in Jiangsu were collected and analyzed. Resluts There were 18 males and 3 females in the AEIPF patients with mean age of ( 67.4 ± 8.1) years. The duration from IPF diagnosis was ( 7.4 ±8.2) months. The duration of acute symptom before admission was ( 7.0 ±5.3) days. The distribution pattern of new groud-glass opacity was peripheral in 3 patients,multifocal in 5 patients, and diffuse in13 patients. All patients were treated with corticosteroid pulse therapy. Nine patients survived and 12 patients died. The mortality rate was 57.1% . Conclusions AEIPF progresses quickly and the mortality rate is very high. Corticosteroid pulse therapy is the mainstay of therapy in AEIPF patients.
目的:探讨基因重组人生长激素(recombinant human growth hormone, rhGH)对特发性矮小儿童促身高增长的疗效。方法:ISS儿童60例,每晚睡前接受rhGH治疗0.15～0.18 IU/(kg·d),疗程3～9个月,并对其疗效进行观察。结果:ISS患儿经生长激素治疗后,生长速率明显增快,由治疗前4.21±0.36 cm/年提高到治疗后8.29±4.72 cm/年,差异有显著性(Plt;0.05)。而骨龄和体重无明显变化,差异不显著(Pgt;0.05)。治疗期间除少数肝功能轻度异常,注射部位轻度反应外,未发现明显副作用。结论:rhGH对ISS儿童有增快生长速度作用。
Idiopathic thrombocytopenic purpura (ITP) is a common bloody disease with a high incidence in children, but its diagnostic method is exclusive diagnosis, and the existing detection techniques are mostly invasive, which may cause secondary injury to patients and also may increase the risk of disease. In order to make up for the lack of the detection method, this study made a preliminary exploration on the diagnosis of children's ITP from the perspective of infrared thermography. In this study, a total of 11 healthy children and 22 ITP children's frontal infrared thermal images were collected, and the pattern characteristic (PFD), average temperature (Troi) and maximum temperature (MAX) characteristics of 7 target areas were extracted. The weighted PFD parameters were correlated with the platelet count commonly used in clinical diagnosis, and the sensitivity and specificity of the weighted PFD parameters for children's ITP were calculated through the receiver operating characteristic curve (ROC). The final results showed that the difference of the weighted PFD parameters between healthy children and ITP children was statistically significant, and the parameters negatively correlated with platelet count. Under the ROC curve, the area under the curve (AUC) of this parameter is as high as 92.1%. Based on the research results of this paper, infrared thermography can clearly show the difference between ITP children and healthy children. It is hoped that the methods proposed in this paper can non-invasively and objectively describe the characteristics of ITP infrared thermal imaging of children, and provide a new ideas for ITP diagnosis.
ObjectiveTo review the recent progress in research on the role of estrogen and estrogen receptor on the onset and progression of adolescent idiopathic scoliosis (AIS). MethodsThe recently published clinical and experimental 1iterature at home and abroad on abnormality of estrogen and its receptor in AIS was reviewed and summarized. ResultsThere are many abnormal changes of estrogen and estrogen receptor in most AIS patients, including higher serum estrogen concentration, unusual cellular response to estrogen, late age at menarche, and gene polymorphisms of estrogen receptor, which are closely associated with AIS predisposition, curve severity, and scoliosis progression. ConclusionEstrogen and its receptor participate in the onset and progression of AIS by certain mechanisms, but exact mechanism remains indefinite, which needs further research to better define the role of estrogen and its receptor in AIS.
Idiopathic pulmonary fibrosis (IPF) is a chronic fibrotic and interstitial lung disease of unknown cause. It has a serious impact on people's health. Traditional Chinese medicine (TCM) has certain advantages in diagnosing and treating on IPF, which have been widely used in clinic. In order to improve the diagnostic and treatment level for IPF with TCM. The Internal Medicine Committee of World Federation of Chinese Medicine Societies organized and established a multidisciplinary background working group. The document was formulated by referring to the formulation method and process of clinical practice guidelines, which are based on the best evidence and the opinions of clinical physicians and patients. Physicians can use this guideline to make clinical decisions.
ObjectiveTo observe the children with idiopathic epilepsy who received AED therapy and seizure-free, withdrawal at least 1 year, and analyze the risk factors of seizure recurrence. In order to give better instructions for AED withdrawal of children with idiopathic epilepsy in pediatric department. MethodsChildren with idiopathic epilepsy who were seizure-free and had stopped AED treatment at least 1 year before the deadline of observation were collected from pediatric outpatient and inpatient department of the First Affiliated Hospital of Guangxi Medical University from January 2011 to January 2014. The following variables, derived from the case records were analyzed: sex, age at seizure onset, type of seizure, time period between the onset of the first seizure and start of treatment, number of seizures in the time period between the start of AED therapy and the last seizure, number of AEDs before remission, time period between the start of AED therapy and the last seizure, time period between the last seizure and withdrawal of AED treatment (seizure-free period, timing of AED withdrawal), time period between the start of AED withdrawal and total discontinuation(speed of withdrawal), EEG registered at the time of diagnosis, before AED withdrawal, during and after AED withdrawal, and the condition of recurrence, data analysed by multi-variate step-wise Cox regression model analysis. ResultsA total of 16(12.8%) children relapsed in a total number of 125 children with idiopathic epilepsy we collected; date evaluated by multi-variable analysis showed that the children suffering from seizure type of focal seizure, starting withdrawal after a seizure-free period of less than 3 years and with abnormal post-withdrawal EEG recording was associated with a higher risk of seizure recurrence. ConclusionsChildren with idiopathic epilepsy have a low risk of recurrence after AED withdrawal. Those who suffer from seizure type of focal seizure, start withdrawal after a seizure-free period of less than 3 years and with abnormal post-withdrawal EEG recording are associated with a higher risk of seizure recurrence.
