BACKGROUND Thermal injuries on free transferred or replanted tissues resulting from loss of sensibility are an infrequent occurrence.They require immediate and appropriate management before they progress to an irreversible condition.Although negative pressure wound therapy(NPWT)can prevent wound progression by increasing microcirculation,the inappropriate application of NPWT on complicationthreatened transferred and replanted tissues can induce an adverse effect.CASE SUMMARY A 48-year-old woman who underwent immediate breast reconstruction with a deep inferior epigastric artery perforator free flap.While applying a heating pad directly to the flap site,she sustained a deep second to third-degree contact burn over 30%of the transferred flap on postoperative 7 d.As the necrotic changes had progressed,we applied an NPWT dressing over the burned area after en-bloc debridement of the transferred tissues on postoperative 21 d.After 4 d of NPWT application,the exposed fatty tissues of the flap changed to dry and browncolored necrotic tissues.Upon further debridement,we noted that the wound gradually reached total necrosis with a collapsed vascular pedicle of deep inferior epigastric artery.CONCLUSION Although NPWT has been shown to be successful for treating various wound types,the significant risk of NPWT application in short-lasting reconstructed flap wounds after thermal injury should be reminded. 展开更多

Laparoscopy is one of the most frequently preferred surgical options in gynecological surgery and has advantages over laparotomy, including smaller surgical scars, faster recovery, less pain and earlier return of bowel functions. Generally, it is also accepted as safe and effective and patients tolerate it well. However, it is still an intra-abdominal procedure and has the similar potential risks of laparotomy, including injury of a vital structure, bleeding and infection. Besides the wellknown risks of open surgery, laparoscopy also has its own unique risks related to abdominal access methods,pneumoperitoneum created to provide adequate operative space and the energy modalities used during the procedures. Bowel, bladder or major blood vessel injuries and passage of gas into the intravascular space may result from laparoscopic surgical technique. In addition, the risks of aspiration, respiratory dysfunction and cardiovascular dysfunction increase during laparoscopy. Large bowel injuries during laparoscopy are serious complications because 50% of bowel injuries and60% of visceral injuries are undiagnosed at the time of primary surgery. A missed or delayed diagnosis increases the risk of bowel perforation and consequently sepsis and even death. In this paper, we aim to focus on large bowel injuries that happen during gynecological laparoscopy and review their diagnostic and management options. 展开更多

Background: The activities carried out by soldiers in the army involve great physical demands and require intense trainings to perform combat-specific tasks. Musculoskeletal injury is a potential threat to the health and physical integrity of the soldier. This study aimed to evaluate the prevalence of lower limb musculoskeletal injuries among soldiers and to propose a training protocol to prevent the most frequent injuries.Methods: This observational(cross-sectional) study recruited a sample of 103 soldiers who required medical attention,from a total 202 new battalion soldiers. The medical records(paper and online) had a form of running text. All data collected were recorded by the registered physicians of the battalion medical post. The records were analyzed by the following variables: medical diagnosis, injury site, mechanism, type of treatment, time loss, existence of previous injury,and recurring injury.Results: A total of 112 musculoskeletal injuries were diagnosed in 71 soldiers, and other types of diseases/injuries were diagnosed in the other soldiers. Joint pain accounted for 55.4% of the diagnoses. The knee was the most affected site, while trauma and overload were the most common mechanisms of injury. Drug treatment was used most frequently, accounting for 58% of the cases. The majority of the sample obtained a temporary leave of absence for1 to 6 days or not at all. Previous injuries and recurrence were not presented as risk factors for injury. With the data received, a protocol for the prevention of injuries to the lower limbs was proposed.Conclusions: This study indicated that the most frequent site of injury is the knee, and joint pain is the most common diagnosis. These results may support the necessity to develop a neuromuscular training protocol to prevent lower limb injuries, which we suggest to be applied in future studies. 展开更多

BACKGROUND Recently,two naval pilots in a two-seat trainer jet were forced to eject urgently due to sudden mechanical failure during night-time training.They were both successfully rescued and sent to the hospital for emergency treatment.In this study,we investigate their ejection injuries and recovery process.CASE SUMMARY We analyzed the clinical data of the traumatic condition and recovery process from ejection injuries of two pilots who ejected from a failed trainer jet and survived.After being successfully rescued and sent to the hospital,they were diagnosed with multiple ejection injuries,including eye trauma,limb bone and joint injury,rib and spine injury,and so on.Both cases underwent fluid replacement,acid suppression,nutritional support,hemostasis,bone metabolism improvement,phlegm elimination,psychological measurement,blood circulation promotion and detumescence,physical therapy,and external fixation with braces for 1 mo before being discharged from hospital.They then recuperated in a sanatorium for 2 mo,and the related laboratory tests and supplementary examinations show that they recovered from all the above injuries.After successfully passing the psychological test and physical examination,they returned to flight duty 3 mo after ejection.CONCLUSION The causes and conditions of ejection injury in the pilots were very complex.Although they finally recovered quickly and were released,it also serves as a reminder that attention should be paid to pilots’ejection and parachute training in order to significantly reduce ejection injury and improve the ejection success rate.In addition,air defense support personnel should strengthen search and rescue and on-site emergency measures,and locate and rescue pilots in distress as early as possible to reduce subsequent injuries. 展开更多

The objective of this study was to describe the management of these lesions, and to identify signifiant risk factors associated with mortality in patients with a PCCW. <strong>Methods.</strong> It was a transversal, descriptive and analytical study performed in Departmental Teaching Hospital of Borgou and Alibori in Benin. From January 1, 2015 to June 30, 2020, patients with a PCCW were retained. Risk factors of mortality and morbidity associated to etiological, clinical and surgical parameters were assessed using the chi-square test. p value < 0.05 was considered to be statistically significant. <strong>Results.</strong> During the study period, 1267 cases of traumatic brain injuries (TBI) were admitted. Of these patients, 77 (6.1%) cases of PCCW were retained. These patients were divided into 66 (85.7%) male and 11 (14.3%) female. The mean age of the patients was 22.6 ± 14.8 years (range from 2 years to 70 years). The circumstances of occurrence were a traffic accident in 42 (54.5%) cases, an assault in 33 cases (42.9%) and a fall 2 (2.6%). The PCCW was unilateral in 71 cases (92.2%). A brain CT-scan was performed in 60 (77.9%) patients. Surgery was performed in 69 (89.6%) patients. Post-operative outcomes were simple in 59 (85.5%) cases. GCS, pupillary abnormalities, motor deficit were a statistically significant risk factor associated with death or sequels (p < 0.0001).<strong> Conclusion.</strong> The identification of risk factors of mortality or sequels is a major step for an efficient management of PCCWs and a reduction of morbidity and mortality. Whatever strategies are adopted, prevention must remain a priority. 展开更多
