Long-Term Survival and Causes of Death in Patients below the Age of 60 with Traumatic Spinal Cord Injury in Germany

To study the mortality, cause and risk indicators of death in German patients with traumatic spinal cord injury, patients with traumatic spinal cord injury admitted to Berufsgenossenschaftliches Trauma Hospital Hamburg between 1 January 1997 and 31 December 2018, aged between 16 and 60 with a minimal survival of one year after injury, were included. Further criteria were the absence of life-limiting comorbidities at the time of injury. 223 deceased patients with traumatic spinal cord injury were identified, investigated on and partly compared to the surviving subjects. We aimed to discover specific complications that were related to Spinal Cord Injury and responsible for a possibly limited life expectancy. Data collection was performed during in- and outpatient treatment. A statistical analysis was performed to compare groups. The post-injury life expectancy was 25.0 years with a significant correlation regarding the level of lesion and severity of injury. The leading causes of death were cardiovascular diseases and pneumonia. Bladder cancer was the most common fatal malignant tumor. The life expectancy of patients suffering from traumatic spinal cord injury is limited. The longer a patient survives after injury and the lower the level of lesion, the more likely an age-related cause of death becomes. Bladder cancer is significantly more frequent when compared to the overall distribution of tumor diseases in Germany

Radiation Dose to the Eye Lens through Radiological Imaging Procedures at the Surgical Workplace during Trauma Surgery

Background: Due to the drastic reduction of the eye lens dose limit from 150 mSv per year to 20 mSv per year since 2018, the prospective investigation of the estimated dose of the eye lens by radiological imaging procedures at the surgical site during trauma surgery in the daily work process was carried out. This was also necessary because, as experience shows, with changes in surgical techniques, there are also changes in the use of radiological procedures, and thus an up-to-date inventory can provide valuable information for the assessment of occupationally induced radiation exposure of surgical personnel under the current conditions. Methods: The eye lens radiation exposure was measured over three months for five trauma surgeons, four hand surgeons and four surgical assistants with personalized LPS-TLD-TD 07 partial body dosimeters Hp (0.07). A reference dosimeter was deposited at the surgery changing room. The dosimeters were sent to the LPS (Landesanstalt für Personendosimetrie und Strahlenschutzausbildung) measuring institute (National Institute for Personal Dosimetry and Radiation Protection Training, Berlin) for evaluation after 3 months. The duration of the operation, occupation (assistant, surgeon, etc.), type of surgery (procedure, diagnosis), designation of the X-ray unit, total duration of radiation exposure per operation and dose area product per operation were recorded. Results: Both the evaluation of the dosimeters by the trauma surgeons and the evaluation of the dosimeters by the hand surgeons and the surgical assistants revealed no significant radiation exposure of the eye lens in comparison to the respective measured reference dosimeters. Conclusions: Despite the drastic reduction of the eye lens dose limit from 150 mSv per year to 20 mSv per year, the limit for orthopedic, trauma and hand surgery operations is well below the limit in this setting

Association of medial collateral ligament complex injuries with anterior cruciate ligament ruptures based on posterolateral tibial plateau injuries

Abstract Background The combined injury of the medial collateral ligament complex and the anterior cruciate ligament (ACL) is the most common two ligament injury of the knee. Additional injuries to the medial capsuloligamentous structures are associated with rotational instability and a high failure rate of ACL reconstruction. The study aimed to analyze the specific pattern of medial injuries and their associated risk factors, with the goal of enabling early diagnosis and initiating appropriate therapeutic interventions, if necessary. Results Between January 2017 and December 2018, 151 patients with acute ACL ruptures with a mean age of 32 ± 12 years were included in this study. The MRIs performed during the acute phase were analyzed by four independent investigators—two radiologists and two orthopedic surgeons. The trauma impact on the posterolateral tibial plateau and associated injuries to the medial complex (POL, dMCL, and sMCL) were examined and revealed an injury to the medial collateral ligament complex in 34.4% of the patients. The dMCL was the most frequently injured structure (92.2%). A dMCL injury was significantly associated with an increase in trauma severity at the posterolateral tibial plateau (p < 0.02) and additional injuries to the sMCL (OR 4.702, 95% CL 1.3–133.3, p = 0.03) and POL (OR 20.818, 95% CL 5.9–84.4, p < 0.0001). Isolated injuries to the sMCL were not observed. Significant risk factors for acquiring an sMCL injury were age (p < 0.01) and injury to the lateral meniscus (p < 0.01). Conclusion In about one-third of acute ACL ruptures the medial collateral ligament complex is also injured. This might be associated with an increased knee laxity as well as anteromedial rotational instability. Also, this might be associated with an increased risk for failure of revision ACL reconstruction. In addition, we show risk factors and predictors that point to an injury of medial structures and facilitate their diagnosis. This should help physicians and surgeons to precisely diagnose and to assess its scope in order to initiate proper therapies. With this in mind, we would like to draw attention to a frequently occurring combination injury, the so-called “unlucky triad” (ACL, MCL, and lateral meniscus).

Urinary bladder cancer as a late sequela of traumatic spinal cord injury

BACKGROUND: Traumatic spinal cord injury (SCI) is also a combat-related injury that is increasing in modern warfare. The aim of this work is to inform medical experts regarding the different course of bladder cancer in able-bodied patients compared with SCI patients based on the latest medical scientific knowledge, and to present decision-making aids for the assessment of bladder cancer as a late sequela of traumatic SCI. METHODS: A study conducted between January 1998 and December 2019 in the BG Trauma Hospital Hamburg formed the basis for the decision-making aids. Urinary bladder cancer was diagnosed in 40 out of 7396 treated outpatient and inpatient SCI patients. General patient information, latency period, age at initial diagnosis, type of bladder management and survival of SCI patients with bladder cancer were collected and analysed. T category, grading and tumour entity in these patients were compared with those in the general population. Relevant bladder cancer risk factors in SCI patients were analysed. Furthermore, relevant published literature was taken into consideration. RESULTS: Initial diagnosis of urinary bladder cancer in SCI patients occurs at a mean age of 56.4 years (SD ± 10.7 years), i.e., approximately 20 years earlier as compared with the general population. These bladder cancers are significantly more frequently muscle invasive (i.e., T category ≥ T2) and present a higher grade at initial diagnosis. Furthermore, SCI patients show a significantly higher proportion of the more aggressive squamous cell carcinoma than that of the general population in areas not endemic for the tropical disease schistosomiasis. Consequently, the survival time is extremely unfavourable. A very important finding, for practical reasons is that, in the Hamburg study as well as in the literature, urinary bladder cancer is more frequently observed after 10 years or more of SCI. Based on these findings, a matrix was compiled where the various influencing factors, either for or against the recognition of an association between SCI and urinary bladder cancer, were weighted according to their relevance. CONCLUSIONS: The results showed that urinary bladder cancer in SCI patients differs considerably from that in able-bodied patients. The presented algorithm is an important aid in everyday clinical practice for assessing the correlation between SCI and bladder cancer

The Real Daily Need for Incontinence Aids and Appliances in Patients with Neurogenic Bladder Dysfunction in a Community Setting in Germany

PURPOSE: For successful long-term rehabilitation of patients with neurogenic lower urinary tract dysfunction (NLUTD), it is necessary to define the objective requirement for urological aids based on a scientifically validated basis. METHODS: This was a cross-sectional multicenter study, based on a questionnaire. Data concerning bladder management and daily consumption of urological appliances for patients with NLUTD in a community setting were collected through a standardized survey. RESULTS: Seven hundred and sixty-seven records were analyzed: 543 males, 221 females (N/A = 3). Patients using intermittent catheterization (n= 608) required 5.06 (mean) single-use catheters per day. Out of them, 94 (15.5%) required additional pads (mean: 2.29 per day), 34 patients (5.6%) additionally used pants (mean: 2.55 per day) and 46 patients (7.6%) utilized condom catheters (mean: 3.81 per day) between catheterizations. Among all, 126 patients (16.4%) used pads (mean: 5.03 per day), and 51 patients (6.6%) used pants (mean: 3.03 per day). Women needed both pads (p &lt; 0.0001) and diapers (p = 0.0084) significantly more frequently than men. Eighty-two of the male patients (15.1%) applied condom catheters (mean: 2.8 per day). The target value of the objective daily requirement of incontinence aids for adult patients with NLUTD (based on the upper twofold standard deviation from the mean value) was defined as follows: up to nine single-use catheters, seven condom catheters, nine pads and/or seven pants. A “mixed supply” of different incontinence aids is part of the daily supply for many patients. CONCLUSION: For the first time, these results allow a reasonable regulation of urological aids and appliances based on scientific data for patients with neurogenic bladder
