[When must the suspicion of an occupational disease or urological sequelae of an occupational accident be reported? : Legal background, medical obligations and course of the procedure]. / Wann sind der Verdacht auf eine Berufskrankheit oder urologische Folgen eines Arbeitsunfalls anzuzeigen? : Rechtlicher Hintergrund, ärztliche Pflichten und Ablauf des Verfahrens.

Physicians are obliged to report the suspected presence of an occupational disease to the German Social Accident Insurance Institutions or to the state authority responsible for occupational health and safety. In the field of urology, tumors of the urinary tract are the most common, followed by the less common renal cell cancer and mesothelioma of the tunica vaginalis testis; however, for such a suspicion to arise at all, sufficient knowledge of urological occupational diseases must be present and the occupational or work history over the entire training and working life since the beginning of employment must be collected. In daily life the notification often fails at this point. In addition to the legal foundation and the principal course of the procedure, this article explains how a relevant comprehensive medical history by means of questionnaires can contribute to the fact that neither too many or all tumor diseases are unreflectedly reported, nor that occupational diseases are overlooked due to the lack of a medical history or detailed knowledge (or fear of this). Urological sequelae of accidents are often not adequately appreciated in the primary process or may take a long time to develop. In this case reporting the aggravation of the consequences of the accident is essential.

[Occupational cancers in urology]. / Berufsbedingte Krebserkrankungen in der Urologie.

Cancers can be triggered by occupational causes. In the field of urology, bladder cancer is by far the most frequent occupationally induced tumor disease. Causes are particularly carcinogenic aromatic amines and carcinogenic polycyclic aromatic hydrocarbons. The frequency of this disease has shifted over the last decades from the classical hazard in the chemical industry to the users. Among a variety of hazardous occupations, hairdressers and painters are the best known. Rarely, renal cell carcinoma can be triggered by high trichloroethylene exposure and mesothelioma of the tunica vaginalis testis by asbestos. If a disease that can be caused by occupational activities has been confirmed (e.g. urinary bladder cancer), the risk factors must be recorded by a complete occupational history from the first employment on in order to be able to report a suspected occupational disease. In addition, spinal cord injury due to occupational and commuting accidents can lead to urinary bladder cancer over the long term.

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.
