OBJECTIVETo study clinical results of reduction and fixation under arthroscopy for the treatment of osteochondrotical lesion in the knee.

METHODSFrom December 2012 to December 2013, 4 patients with the knee joint osteochondritis lesion and free bone fragments were treated with arthroscopy to detect the stripped cartilage, and then the cartilages were reduced with small incision and fixed by cartilage nail. There were 3 males and 1 female, with age of 15, 15, 20 and 27 years old. The durations of the disease were 1 d, 5 d, 1 month and 1 year. All the patients had swelling and effusion in the knee joint, and the floating patellar test was positive. CT examination showed bone defects and loose bodies. The Lysholm, VAS, and Tegner scale were used to evaluate the knee joint functions before and after operation.

RESULTSAll the patients underwent successful surgery. Postoperative CT showed good location of the cartilage without loss of reduced bone and cartilage. All the patients were followed up, and the duration ranged from 10 to 13 months, with a mean of 12 months. In one patient, arthroscopy examination was conducted for a second time to examine the connection of the fracture part to the surrounding cartilage, and it showed that the internal fixator was not absorbed. The Lysholm, VAS and Tegner scale of all patients were better than those before operation.

CONCLUSIONTreatment of osteochondritis lesion with the fixation of absorbable cartilage nails may reconstruct the integrity of articular surface and recover the stability of joints, and it is an effective treatment method.

ObjectiveFew studies are reported on the sublingual immunotherapy with dermatophagoides farinae drops (DFD) for mite-allergic cough variant asthma (CVA) in children. This study aimed to investigate the clinical effects of DFD sublingual immunotherapy on mite-allergic CVA in children.MethodsWe retrospectively analyzed the clinical data on 225 children with mite-allergic CVA treated in Wuhan Children′s Hospital from January 2016 to January 2017. The patients were divided into a control (n=123) and an experimental group (n=102) to receive symptomatic treatment and symptomatic treatment combined with DFD sublingual immunotherapy, respectively, both for 10 months. We recorded the relevant indicators, including the symptom scores, lung function parameters, levels of dust mite IgE and inflammatory factors (IL-4, TGF-β and INF-γ), and related risk factors, and compared the data obtained between the two groups of patients before and after treatment.ResultsThere were no statistically significant differences between the two groups of patients in the baseline daily and nocturnal cough symptom scores, lung function parameters, or levels of serum IgE, IL-4, TGF-β and INF-γ (P>0.05). After treatment, the children in the experimental group showed markedly lower daily and nocturnal cough symptom scores than the control (0.87±0.06 and 0.91±0.11 vs 2.54±0.32 and 2.38±0.42, P<0.05), better pulmonary function parameters (FEV1/FVC: \[1.98±0.56\]% / \[79.67±9.05\]% vs \[1.65±0.37\] / \[75.87±11.56\]%, P<0.05), and a higher effectiveness rate (73.53% vs 54.47%, P<0.05). The single- and multi-factor analyses showed that age, disease course and treatment methods were independent risk factors influencing the therapeutic effect on mite-allergic CVA in children (P<0.05).ConclusionSublingual immunotherapy with DFD can effectively improve the clinical symptoms and lung function in children with mite-allergic CVA, which may be associated with the decreased levels of serum IgE, IL-4, TGF-β and INF-γ. Age, disease course and treatment methods are independent risk factors influencing the therapeutic effect.

Post-traumatic stress disorder (PTSD) is the most serious post-disaster physical and mental barrier, and intellectual disabilities are more sensitive to the negative effects caused by trauma than the healthy population. The debate existing extensively makes the diagnosis of PTSD in patients with intellectual disability difficult to be understood. There is a need to use uniform diagnostic criteria, howere, it still remains a problem for less experienced clinicians.

Objective To investigate the differences of clinical characteristics and disease severity between respiratory syncytial virus (RSV) and non-RSV bronchiolitis.Methods Ninety-six bronchiolitis inpatients of Shengjing Hospital from November 2012 to March 2014 were enrolled.RSV detection was performed at enrollment by direct immunofluorescence assay and the patients were divided into RSV group and non-RSV group.Clinical characteristics were collected and compared, including patients' demographic data, allergy, etc.Clinical scores were assessed by modified-Tal score system, and the associations between clinical scores and duration of onset or length of stay were analyzed to assess disease severity.Results In all 96 patients, forty (46.17％) were determined to be infected with RSV.Patients with RSV bronchiolitis were younger at hospitalization (t =-2.706,P =0.008) and the weight was lower (t =-2.070, P =0.041).There was no significant differences in sex, birth way, birth weight, height, ete (P ＞ 0.05).There was no significant differences in eczema, history of family allergy and total serum IgE (P ＞ 0.05).For patients with RSV bronchiolitis, the clinical scores were higher (t =-0.405 ,P ＜0.001) and the length of stay trended to be longer (t =0.480 ,P =0.081).The clinical score had a positive relation with length of stay (r =0.305, P =0.003), but not with the duration of onset (P ＞ 0.05).Conclusion Compared with non-RSV bronchiolitis, the clinical characteristics of patients with RSV bronchiolitis are younger age and lower weight, and have higher clinical scores, which indicates the clinical conditions may be more severe.For bronchiolitis, there is a positive correlation between clinical score and length of stay.The combination of etiological detection and modified-Tal score system may help to recognize severe cases, which should be observed carefully and treated immediately.
