Objective To study the relevant factors and prevention of X-ray missed diagnosis in rib fracture.Methods 28 cases of rib fracture in the X-ray missed diagnosis were retrospectively reviewed. The relevant factors and preventive question of X-ray missed diagnosis were explored.Results Careless reading of film(n=3),wrong position of taking film(n=7),film of low quality(n=4),image of rib fracture concealed by other image (n=11) and improper time of taking film(n=3) were found as the cause of missed diagnosis.Conclusions The X-ray examination of chest is the most practical method in diagnosing rib fracture. The choice of position in taking film,quality assurance of film,the right time in taking film and carefulness in reading film may affect the diagnosis of rib fracture.

ObjectiveTo investigate the clinical features of postpartum hemolytic uremic syndrome (PHUS) in Tibetan women, and to improve the diagnosis and treatment of PHUS.MethodsFrom January 2013 to June 2018, 11 patients diagnosed with PHUS in the Tibet Autonomous Regional People's Hospital were enrolled. Clinical manifestations, laboratory testing results, treatments and outcomes were retrospectively analyzed. A descriptive statistical analysis was applied in this study.ResultsThe average age of the 11 patients was (27.0±6.2) years old, and all were Tibetans. Five of them delivered by cesarean section and eight complicated by hypertension. The onset of PHUS was 1-3 d after delivery. The mean hemoglobin concentration [(73.5±26.3) g/L] and platelet count [(51±31)×109/L] remarkably decreased. Patients' renal functions were also significantly impaired with an average serum creatinine level of (517±184)μmol/L. Nine women required hemodialysis, seven received plasma infusion and six underwent glucocorticoid therapy. No patients received plasma exchange or eculizumab therapy due to limited resources. Seven out of the nine patients who underwent hemodialysis could withdraw from dialysis.ConclusionsPHUS is relatively rare, and characterized by acute onset after birth and severe conditions, especially renal injury. However, most patients would have better prognosis after active treatment.

Traumatic rib fractures are the most common injury in thoracic trauma. Previously,the patients with traumatic rib fractures were mostly treated non-surgically,of which 50%,especially those combined with flail chest presented chronic pain or chest wall deformities and over 30% had long-term disabilities,being unable to retain a full-time job. In the past two decades,thanks to the development of internal fixation material technology,the surgical treatment of rib fractures has achieved good outcomes. However,there are still some problems in clinical treatment,including inconsistency in surgical treatment and quality control in medical services. The current consensuses on the management of regional traumatic rib fractures published at home and abroad mainly focus on the guidance of the overall treatment decisions and plans,and relevant clinical guidelines abroad lacks progress in surgical treatment of rib fractures in recent years. Therefore,the Chinese Society of Traumatology affiliated to Chinese Medical Association and Chinese College of Trauma Surgeons affiliated to Chinese Medical Doctor Association,in conjunction with national multidisciplinary experts,formulate the Chinese Consensus for Surgical Treatment of Traumatic Rib Fractures(2021)following the principle of evidence-based medicine,scientific nature and practicality. This expert consensus puts forward some clear,applicable,and graded recommendations from aspects of preoperative imaging evaluation,surgical indications,timing of surgery,surgical methods,rib fracture sites for surgical fixation,internal fixation methods and material selections,treatment of combined injuries in rib fractures,in order to provide references for surgical treatment of traumatic rib fractures.
