Objectives To detect genetic causes of dystrophic epidermolysis bullosa (DEB). Methods Next-generation sequencing was used to detect a neonate with DEB. Sanger sequencing was used to confirm the results and detect his parents and grandmother on his mother side from the family. Results The neonate was found to have heterozygous mutation c.6781C>T of exon 86 in COL7A1 gene.This mutation results in R2261X nonsense mutation in typeⅦcollagen. His mother and grand-mother on his mother side have the same mutation. Conclusion Next-generation sequencing technology is a useful tool for the detection of mutations of COL7A1 gene, which is valuable for clinical application.

Objective To survey the prevalence of undemutrition in elderly leprosy patients and explore the feasibility of nutritional assessment. Methods The nutrition status of 60 elderly patients with advanced leprosy was analyzed using Subjective Global Assessment (SGA) and objective methods. Results Undemutrition was determined in 22 patients (36. 6% ), including 5 patients ( 8. 3% ) were at a status of severe undernutrition. Kap-pa value of SGA and the objective items were 0. 619, 0. 571, 0. 476, 0. 454, and 0. 419 for triceps skin-fold thickness (TSF), pre-albumin (PALB), mid arm muscle circumference (MAMC), hemoglobin (Hb), and ser-um albumin, respectively. Gender, admission duration, type of leprosy, or disability grade was not correlated to all nutritional parameters except body height and cholesteroL Age and extent of ulceration were significantly correlated with some parameters such as BMI, TSF, lib, ALB, and PALB ( P < O. 01 ). Sensitivity and specificity of SGA on objective parameters screened were different. TSF and ulcer had the hrgest impacts on SGA. Conclusions The prevalence of undernutrition is not high in elderly leprosy patients. Any single objective parameter is not feasible for the assessment of nutrition status in these patients. A comprehensive method using SGA is preferred.

Objective To evaluate the diagnostic value of lung ultrasonography for transient tachypnea of new-born (TTN).Methods From January to December 201 4,a total of 1 358 children were hospitalized in the Neonatal Intensive Care Center and underwent lung ultrasonography at the Bayi Children′s Hospital,Beijing Military General Hospital.According to the patients′medical histories,clinical presentations,arterial blood gas analysis,chest X -ray examinations,and lung ultrasound examinations,there were 41 2 cases of patients without pulmonary lesions,228 cases of TTN,358 cases of respiratory distress syndrome (RDS),85 cases of meconium aspiration syndrome (MAS),21 5 ca-ses of infectious pneumonia,and 60 other cases at the time of hospital admission.In a resting state,the patients were placed in a supine,lateral recumbent or prone position.By using the anterior and posterior axillary lines as boundaries, the lung was divided into 3 regions:anterior,lateral,and posterior.The probe was perpendicular or parallel to the ribs, and each region of both sides of the lung was scanned.The scan results were compared to the conventional chest X -ray results.Results The main ultrasonic characteristics of TTN was pulmonary edema.In severe cases,the ultrasound showed a white lung or compact B -line.Compact B -line had 1 00.0% sensitivity and 95.3% specificity for diagno-sing severe TTN.Mild TTN presented as pulmonary interstitial syndrome or double lung point.Double lung point might appear during the recovery period of mild TTN or other diseases,such as RDS,MAS,and pneumonia,among others. Lung consolidation and air bronchogram were not observed in patients with TTN.Pleural effusion might occur in a varie-ty of lung diseases,and pleural line abnormality,A -line disappearance,and B -line or pulmonary interstitial syndrome were common ultrasonic manifestations of a variety of lung diseases.Conclusions Ultrasonic diagnosis of TTN,mainly based on pulmonary edema without lung consolidation and air bronchogram,is accuracy and reliable;however,double lung point is not a specific sign of TTN,whereas the identification of a white lung and compact B -line is a sensitive and specific sign of severe TTN.

Objective To evaluate the value of lung ultrasound in diagnosing infectious pneumonia (IPN) of newborns. Methods Seventy-two infants hospitalized from September 1, 2012 to May 30, 2013, in Bayi Children's Hospital, General Hospital of Beijing Military Command were divided into two groups. The study group consisted of 32 newborn infants diagnosed as IPN by medical history, clinical manifestations and chest X-ray, while the control group consisted of 40 neonates without any lung diseases. In a quiet state, the infants were placed in supine, side or prone position for lung ultrasound examination. The lung field was divided into three areas by the anterior and posterior axillary line. The regions of the bilateral lung were scanned by the probe which was vertical with the ribs. Fisher's exact was performed for stastical analysis. Results The most important ultrasound imaging findings of IPN included lung consolidation of varying size and shape with irregular and serrated margins (100%, 32/32), dynamic air bronchograms (100%, 32/32), A-line disappearance (100%, 32/32) and interstitial syndrome (100%, 32/32). Other common ultrasound signs included pleural line abnormalities (91%, 29/32), lung pulse (38%, 12/32) and dynamic air bronchograms (66%, 21/32) under real-time ultrasound. Pleural effusion was an infrequent sign that existed in 9%(3/32)of IPN patients. None of these abnormalities was observed in the control group. Conclusion Lung ultrasound is reliable for the diagnosis of IPN and can be routinely performed in neonatal intensive care units, and a large area of lung consolidation with irregular margins A-line disappearance, interstitial syndrome and pleural line abnormalities are the main image findings.
