Treatment‐related infertility is a common problem in cancer survivors. Semen cryopreservation is the most established option for male oncological patients wishing to preserve their fertility. We conducted a systematic review to analyse the existing literature regarding the frequency of offers and attempts of semen cryopreservation. We systematically searched MEDLINE and EMBASE for eligible literature without restrictions to language, study type or year of publication. Two authors independently screened and evaluated the citations for eligibility. Studies were included if they reported on pubertal or post‐pubertal patients at risk of fertility impairment prior to their cancer therapy. We excluded studies neither reporting the prevalence of offer nor attempt of semen cryopreservation. Possible factors for heterogeneity between the studies were examined by meta‐regression analyses. Out of 6,105 returned citations, 42 studies were included in the analysis. The prevalence of offer varied from 8% to 100% and corresponding attempts ranged from 3% to 79%, showing a vast heterogeneity with inconsistent reporting of influencing variables. Measured by the number of scientific publications, the awareness for fertility preservation is increasing while actual prevalences are diverse. In order to identify variables influencing offer and attempt prevalences, consistent reporting of a core set of factors is required.
Summary
Background
In recent years, emergency consultations have become more common in all medical disciplines. In Germany, dermatological out‐of‐hours consultations are handled by emergency practices, emergency departments and tertiary care providers. Little information is available on the reasons for these dermatological consultations.
Objectives
The aim of this study was to analyze patient characteristics, diagnoses and admission rates resulting from these consultations.
Methods
We conducted a retrospective study covering two years of out‐of‐hours consultations at a dermatological tertiary referral center.
Results
A total of 3635 patients presented at the referral center. The most frequent outpatient diagnoses were acute urticaria (13.8 %) and bacterial infections (12.3 %). 83 % of the outpatient diagnoses required the most advanced competence level according to the new German curriculum for undergraduate education of medical students. 405 (11.01 %) patients did not require dermatological treatment, and 430 patients (13.6 %) were admitted to hospital. Most admissions were due to bacterial infections and herpes zoster. Advanced age, pain and fever were associated with a relatively high risk of admission.
Conclusions
Admission rates at the dermatological tertiary referral center were substantially lower than at interdisciplinary emergency departments. A few diagnoses accounted for more than half of all consultations. These diagnoses are well represented within the new German curriculum.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
