Understanding the features of the various hereditary vascular pathologies allows consideration and confirmation of the diagnosis, and a search for treatable hidden disorders, avoiding harmful investigations, initiating follow up, performing family investigations and providing genetic counselling. Pseudoxanthoma elasticum must be considered in the presence of calcified distal arteriopathy of the lower limbs in a young subject without any other aetiological aspects. Cutaneous or mucosal lesions confirmed on histological examination, angioid streaks at the back of the eye and a family history support the diagnosis, which is confirmed by showing pathogenic mutations of the ABCC6 gene. It is then important to search for a peripheral disorder in other arterial territory, a low grade coronaropathy, hypertension and an endocardial disorder. Prescription of antithrombotics must be made carefully because of the risk of gastro-intestinal haemorrhage. Vascular Ehlers-Danlos syndrome is suspected in a subject less than 30 years old with diffuse aneurysmal disease, spontaneous arterial rupture or dissection, a carotido-cavernous fistula or early onset
varices
. Demonstrating an ecchymotic tendency or an acrogeric morphology, especially in a familial context, warrants cutaneous biopsy for anatomopathological examination and fibroblast culture for a study of the C0L3A1 gene. When the diagnosis is suggested, it is advisable to prohibit any arterial puncture, cold surgery or gastro-intestinal endoscopy. The search for aneurysmal lesions must be performed by non-invasive imaging. The therapeutic management requires specialised teams. The combination of repeated epistaxis, muco-cutaneous telangectasia and similar characteristics in a family suggests the diagnosis of Osler-Weber-Rendu disease. The search for
iron deficiency
, gastro-intestinal bleeds and pulmonary, hepatic or cerebral arterio-venous malformations is then necessary. Besides skilled endovascular management when indicated, it is important to advise every patient with a pulmonary arterio-venous malformation to take antibiotic prophylaxis against cerebral abscess in situations at risk of bacteraemia.

Medical laser applications based on widespread research and development is a very dynamic and increasingly popular field from an ecological as well as an economic point of view. Conferences and personal communication are necessary to identify specific requests and potential unmet needs in this multi- and interdisciplinary discipline. Precise gathering of all information on innovative, new, or renewed techniques is necessary to design medical devices for introduction into clinical applications and finally to become established for routine treatment or diagnosis. Five examples of successfully addressed clinical requests are described to show the long-term endurance in developing light-based innovative clinical concepts and devices. Starting from laboratory medicine, a noninvasive approach to detect signals related to
iron deficiency
is shown. Based upon photosensitization, fluorescence-guided resection had been discovered, opening the door for photodynamic approaches for the treatment of brain cancer. Thermal laser application in the nasal cavity obtained clinical acceptance by the introduction of new laser wavelengths in clinical consciousness.
Varicose veins
can be treated by innovative endoluminal treatment methods, thus reducing side effects and saving time. Techniques and developments are presented with potential for diagnosis and treatment to improve the clinical situation for the benefit of the patient.

Iron deficiency
is the most common etiology of anemia worldwide and is often managed with varying methods of iron supplementation. Although rare, oral iron supplementation can perpetuate iron deficiency anemia by causing gastric ulceration and upper gastrointestinal bleeding in high-risk populations. However, this complication has not been previously described with intravenous iron supplementation. We present a case of a 63-year-old male with severe iron deficiency anemia on biweekly intravenous iron infusions and weekly packed red blood cell transfusions who presented with melena over several months. Upper endoscopy demonstrated a clean-based gastric body ulcer and nonbleeding gastric
varices
. Histology of the gastric ulcer was suggestive of iron-induced gastric mucosal injury. This case demonstrates that frequent utilization of intravenous iron and packed red blood cell transfusions may predispose certain patients to the development of iron-induced gastritis and ulceration.
