    Laboratory tests

    All state of the art laboratory tests are available in more than 30 countries.

    broken image

    MRI, CT, TCS

    Our partner practices and clinics perform examinations with MRI, CT and TCS (sonography of the brain). Scintigraphy is also still possible but less common than in the past. Due a three-step diagnostic procedure you will get an unusually high level of safety.

    Neurological exams

    All standard neurological tests are being provided by carefully selected partners in over 50 countries.

  • Together.

    Closer to you than you might think.

    As an international reference practice for rare diseases, we recognize that it’s not feasible for every patient to travel to Athens or for our team to journey globally. This is why we have established excellent partnerships in numerous countries. Take a look at our world map: the countries highlighted indicate where we have access to partner physicians and infrastructure. This means shorter travel distances for our patients and the reassurance of being in safe hands.

     

    We also make house calls to our long-standing patients, provided they reside in the EU. We have also acquired the Clinico platform for this purpose.

     

    After completing diagnostics and achieving a sustainable treatment plan, we recommend trusted general practitioners to our patients. While patients are free to choose their own doctors, we find it beneficial to work with GPs who are comfortable managing and treating rare diseases. Should there be any complications or progression of the illness, rest assured, we are immediately on hand to assist.

    OpenAIRE

     

    We are a proud member of open AIRE (Open Access Infrastructure for Research in Europe) is a European initiative aimed at promoting open access to research outputs and facilitating the discovery and reuse of research information. It provides a platform for researchers, institutions, funders, and policy makers to discover and access the full text of research articles, datasets, and other research outputs, as well as information about projects, funding, and collaborations.

     

    OpenAIRE offers a variety of services and tools for researchers, including a discovery portal for accessing open access research outputs, support for data management and sharing, and integration with research information systems. The initiative also provides guidance and support for researchers and institutions to comply with open access mandates and funding requirements.

     

    OpenAIRE aims to make research outputs more discoverable and accessible, enabling researchers to build on the work of others and facilitate collaboration and innovation in research. It plays a key role in promoting open science and advancing the transition to a more open, collaborative, and transparent research ecosystem.

    How Lazar | Seideman | Smith works

    Clear rules.

     

    Our top priority is to treat you as individually as your condition requires. Remote treatments (video telemedicine) in the strict sense are performed, but only in well-defined cases. Highly qualified colleagues in over 20 countries perform those physical examinations for us which are not possible via video conference and telemedicine.

    broken image

    Prudence, vigilance and diligence.

    Remain humble to what you don’t know.

     

    Since no one is omniscient, being well-networked makes a big difference. Dr. Lazar has always made it a point to network with as many colleagues as possible. After all, there's nothing worse than a doctor who thinks he knows everything. Therefore “better safe than sorry” is his credo.

     

    Dr. Lazar puts great emphasis on continuously educating himself and sharing his knowledge. That's why he also contributed pro bono as an editor to DocCheck's medical encyclopedia, among other projects.

     

    Diagnosing and treating rare diseases is more important than ever. Thousands of rare diseases exist, up to about seven thousand rare diseases have already been described scientifically, and more are being identified on an ongoing basis. Yet they remain mostly unknown in day-to-day medical practice. Medical and scientific knowledge about rare diseases is far from sufficient in the medical profession. The subject area of rare diseases has long been neglected by physicians, politicians and scientists, so that neither appropriate health policies nor scientific initiatives existed.

     

    For most rare diseases there is no efficient therapy, nevertheless appropriate interventions can improve the quality of life and also increase life expectancy. Some impressive progress has been made in the treatment of certain diseases, which should motivate us to intensify research efforts.

     

    Patients with rare diseases mostly face similar problems. Difficulties exist mainly in terms of diagnosis, availability of relevant information and referral to appropriate specialists. Equally important is access to qualified specialist facilities, general social and medical support, effective cooperation between hospitals and general practitioners, professional and social integration or maintaining independence.

     

    Those affected often face psychological, social, economic or cultural problems. Many patients do not receive a diagnosis because the lack of sufficient scientific and medical knowledge means that a rare disease is often not recognized. It is precisely this group of patients that is exposed to the greatest pressure of suffering, as they are denied access to adequate support.

    We are first and foremost human beings.

    And care about our patients, more than usual.

     

    Those with a rare disease who are patients of Lazar, Seideman & Smith see their attending specialist every 10 to 14 days. In addition, a team of assistant physicians with a variety of specialties is available 24 hours a day for our long-term patients. Those who receive their treatment under the Luzia Healthcare u.n.a. social program are not billed for treatment by our assistant doctors. Or, to put it briefly: we take good care of our patients.

    Rare diseases are a challenge

    What we are confronted with.

     

    Orphan diseases, also known as rare diseases, are defined as conditions that affect fewer than 200,000 people in the United States. There are over 7,000 rare diseases affecting approximately 400 million people worldwide. Diagnosis and treatment of rare diseases face several challenges, including:

     

    • Lack of Awareness: As the name suggests, these diseases are “rare” and as such, there is often limited awareness and understanding of these conditions among the general public and even healthcare professionals. This can lead to misdiagnosis and delayed treatment.
    • Limited Research and Development: Due to the small patient population and limited financial incentives, there is often limited research and development into orphan diseases. This can lead to a lack of knowledge about the underlying mechanisms and treatments for these conditions.
    • Lack of Diagnostic Tools: There is often a lack of diagnostic tools and tests for rare diseases, leading to difficulties in accurately diagnosing the condition.
    • Difficulty in Finding Specialists: There may be only a few healthcare professionals who specialize in a particular rare disease, making it difficult for patients to access specialized care and treatment.

    In conclusion, the low prevalence of orphan diseases makes it challenging to diagnose and treat them effectively. The limited research and development, lack of diagnostic tools, and difficulty in finding specialists all contribute to the difficulties faced in diagnosing and treating these conditions.

     

    That's the reason why we do what we do.

  • Our social responsibility

    Everyone should have access to the best possible care.

    Social fee system

    The diagnosis and treatment of rare diseases is complex and requires ongoing consultations between all the physicians involved. Therefore, high costs are a consequence of this process. In order to cushion these effects, we have a fee system that is graduated according to the financial strength of the patients. In this solidarity system, wealthy and well-insured patients enable the treatment of less well-off patients in a mixed calculation.

  • EU-Prescriptions

    In the EU, there is an initiative to facilitate the cross-border validity of medical prescriptions to support patient mobility within the EU. However, EU-prescriptions will remain on paper, not digital because the digital systems across different EU member states are currently quite varied and lack uniformity.

     

    EU prescriptions, valid in all member statea, are expected to remain in paper form, rather than transitioning to digital, for the foreseeable future.

     

    In practice, this means that paper prescriptions continue to play a crucial role, particularly for patients who receive treatment in one EU country but need to obtain medication in another EU country. The use of paper prescriptions in such cases allows pharmacists in the foreign country to more easily understand and dispense the medications as prescribed.

     

    While the EU is working towards harmonizing digital health systems, including e-prescription systems, to improve compatibility and interoperability across different member states, paper prescriptions remain essential for cross-border healthcare within the EU until this harmonization is fully realized in the far future.

  • Independence

    And other principles that are important to us.

    Our international practice for rare neurological diseases always strives to incorporate all the latest research findings directly into the diagnostic process and the treatment of our patients. In doing so, we are guided by the following values, without any exception:

     

    Independence:

    We do not use third-party funds, are not part of unnecessary professional associations, and do not maintain relations with representatives of the pharmaceutical industry.

     

    Security:

    We have all our analog and digital infrastructure regularly audited by the relevant specialists.

     

    Reliability:

    All our international partner practitioners are regularly audited in terms of equipment, quality and patient ratings.

That's why one of the focal points of our work is iron metabolism disorders, which are so much more than just classic hereditary hemochromatosis. We are also quite active in and for the H63D Syndrome Research Consortium.

  • Wir helfen auch auf Deutsch.

    Und das hat einen guten Grund.

    Als einzige hochspezialisierte Netzwerkpraxis für neurologieche, neuroendokrinologische und neurometabolische Erkrankungen, stellen wir konsiliarisch unser Wissen für Ärzte und Patienten zur Verfügung, und dies in der gesamten Europäischen Union. Herr Dr. Lazar und Prof. Dr. Seideman haben beide private enge Bindungen an Deutschland bzw. die deutsche Sprache, so dass das Deutsche sogar eine von mehreren Arbeitssprachen unseres Teams ist. Natürlich pflegen wir auch enge Kontakte zu ärztlichen Kollegen in Österreich, der Schweiz und sporadisch auch in Deutschland, um eine gute Versorgung dieser Patienten am Wohnort sicherstellen zu können. Wir nennen Ihnen gerne Fachärzte für Allgemeinmedizin, hausärztliche Internisten sowie Kollegen aus anderen Fachgebieten im deutschsprachigen Raum. Nehmen Sie einfach über das Formular oder telefonisch Kontakt mit uns auf.

    Hausbesuche

    Wir sind keine lokal fixe Praxis, sondern arbeiten in einem Netzwerk, das ganz die gesamte EU überspannt. Die leitenden Ärtze der LSS unterstützen lokale Kollegen mit ihrem Know-how. Hausbesuche werden in der Regel nur von unseren, hausärztlichen Kollegen im CLINICO Verbund durchgeführt, der ganz besonders in den deutschsprachigen Ländern stark vertreten und verlässlich ist.

  • Rezeptvalidierung für Apotheken

    Unsere Rezepte haben mehrere Sicherheitsmerkmale anhand derer wir Ihnen mitteilen können, ob Ihnen ein echtes Rezept unseres Hauses vorliegt.

    Die vollständige Harmonisierung der digitalen Gesundheitssysteme innerhalb der EU ein langfristiges Projekt ist und auch sehr optimistisch geschätzt nicht vor 2035 realisiert wird. Die Herausforderung liegt nicht nur in der technischen Umsetzung, sondern auch in der rechtlichen und organisatorischen Koordination zwischen den Mitgliedstaaten. Jeder Staat hat eigene Systeme, Vorschriften, Ansätze, Ausnahmen und nationalen Gesetzeslagen zur digitalen Gesundheitsversorgung, die in Einklang gebracht werden müssen, bevor auch das EU-Rezept eines Tages digital werden kann. Bis dahin gilt: Papier, Stempel, Unterschrift. Die Schaffung eines gemeinsamen Europäischen Gesundheitsdatenraums (EHDS) und die damit verbundene Harmonisierung von eHealth-Diensten wie E-Rezepten sind komplexe Unterfangen. Sie erfordern eine enge Zusammenarbeit zwischen den Mitgliedstaaten, die Entwicklung gemeinsamer Standards und die Überwindung von rechtlichen und technischen Hürden.
