Familial spontaneous pneumothorax(FSP) is a specific type of primary spontaneous pneumothorax.FSP means there are more than one individuals develop pneumothorax and is a rare inherited disease.FSP is different from primary spontaneous pneumothorax in several clinical manifestations.So far the genetic basis and inheritance pattern of this disease are not clear.Progress in this field are reviewed here.

Objective:To evaluate the predictive value of stair climbing test combined with arterial blood gas analysis on postoperative complications in lung cancer patients with limited pulmonary function.Methods:A total of 1 231 hospitalized lung cancer patients with limited pulmonary function dating from August 2012 to August 2020 were retrospectively reviewed. Included in the cohort were 766 of patients who underwent stair climbing test(SCT) preoperatively and completed data collection. Patients were grouped according to their general condition, past medical history, surgical approach, pulmonary function test(PFT) and SCT results. Comparison of the postoperative cardiopulmonary complication rates were made between different groups, and independent risk factors were identified.Results:A total of 182 cardiopulmonary-related complications occurred in 144 cases, accounting for 18.8% of the entire cohort. Perioperative mortality rate was 0.9%(7/766). The rate of postoperative cardiopulmonary complications was significantly different between the groups stratified by gender, age, smoking index, PFT index(FEV1%, DLCO%), SCT results(height achieved, speed, changes in heart rate and oxygen saturation of the arteries before and after the test), ASA score, surgical approach(VATS/Open), resection range(Lobectomy/Sublobectomy), anesthetic duration, blood loss volume, etc. Logistic regression analysis showed that only height achieved( P<0.001), changes in heart rate( P<0.001), changes in oxygen saturation of the arteries( P=0.001), resection range( P=0.006) and anesthetic duration( P=0.025) were independent risk factors for cardiopulmonary-related complications in lung cancer patients with limited pulmonary function. Conclusion:The stair climbing test combined with arterial blood gas analysis could be used as a preoperative screening method for lung cancer patients with limited lung function and may have a predictive value for postoperative cardiopulmonary-related complications.

Objective:
To analyze the incidence and possible risk factors of 19 fractured implants out of 8 468 implants in 3 184 cases.
Methods:
During the 22-year clinical practice, clinical records of 18 patients with 19 fractured implants in 3 184 cases with 8 468 implants were analyzed to determine the following factors: location of the fractured implants, prosthodontics option, date of implant fracture, dimensions of fractured implants, complications prior to implant fracture and parafunctional habit. An evaluation of fractured implants was performed to identify possible factors that may predispose an implant to a higher risk of fracture.
Results:
Overall, the average duration of service of the implants was (7.0±4.5) years. Implant fracture occurred in 7 Camlog implants, 7 Nobel replace implants, 3 Ankylos implants and 2 Brånemark implants. No Thommen implant fractures were recorded. Amongst the 19 fractured implants, 8 occurred at the thinnest wall portion of the implant neck, 8 at the end of screw and 3 at the self-tapping thread region. All fractures were observed after functional loading. Furthermore, 9/19 (47.4%) of fractures occurred in the maxilla, indicating similar incidence rates in both arches (
