Paediatric Association of Nigeria - 57th Annual Scientific Conference

IPWSO was proud to support a dedicated PWS symposium at the 57th Annual Scientific Conference of the Paediatric Association of Nigeria (PAN) Conference held 21-23 January 2026 in Ogun State.

Famcare Board Member, Dr Elizabeth Oyenusi, presented on the clinical features, diagnosis, and management of PWS, while Dr Oluwakemi Ashubu shared the first  genetically confirmed case of PWS in the country - an important milestone. The session attracted over 104 delegates and sparked a lively discussion.

IPWSO also hosted an exhbition table throughout the 3-day conference, distributing educational materials  and engaging directly with healthcare professionals.

We are hugely grateful to Dr Oyenusi, Dr Ashubu and Dr Oladipo (Senior Registrar) for their support in making this educational oureach possible - helping to strengthen awareness and improve early diagnosis of PWS in Nigeria. Funding for this event was kindly provided by Friends of IPWSO (USA).

Global Newborn Society Inaugural Conference, Sweden 

The Global Newborn Society’s 1st Conference took place in Uppsala and Stockholm, Sweden, from 2-4 November 2025, marking an exciting milestone for the organisation’s international community.

 We were delighted that Dr Susanne Blichfeldt was invited to deliver a plenary lecture on behalf of IPWSO, titled “Neonatal Hypotonia: Clinical Features Seen in PWS That Can Help Differentiate It from Other Congenital Disorders with Similar Symptoms.”

 The inaugural event brought together a diverse audience of physicians, nurses, and social care leaders from around the world. The programme was wide-ranging and stimulating, featuring cutting-edge discussions on newborn health, early diagnosis, and innovative care practices - setting a strong foundation for future collaboration within this growing global network. 

ASPED 2025, Dubai, UAE

The 6th conference of the Arab Society for Paediatric Endocrinology and Diabetes was held in Dubai over two days on the 26th and 27th September 2025. IPWSO was invited to be a partner and to present at a session on PWS. The conference was attended by over 400 paediatric endocrinologists from more than 20 countries in the Middle East and North Africa. Charlotte Hoybye and Tony Holland attended and presented on behalf of IPWSO and Dr Sarah Ehtisham described her experience seeing patients with PWS in the United Arab Emirates. IPWSO hosted a stand for the whole conference.

In conversation many attendees reported seeing people with PWS and described the challenges they faced, particularly with the management of behaviour problems. Some felt nervous about starting growth hormone as they had had no experience prescribing it to infants with PWS.

Approximately 100 attendees joined the IPWSO mailing list and attendees were very keen to gain knowledge about PWS. Numerous memory sticks with information on PWS and printed material in English and Arabic were taken. Some attendees talked about establishing national or regional PWS Associations.

This was an extremely positive experience and hopefully attending this meeting has laid the groundwork for IPWSO to engage more fully in the Region in the future. We were very well looked after, and the organisers were excellent hosts.

EPNS 2025, Munich, Germany

Together with parents and representatives from the Prader-Willi-Syndrom Vereinigung Deutschland, we were proud to host a PWS exhibition stand at the 16th Congress of the European Paediatric Neurology Society, held in Munich from 8-14 July 2025. The event welcomed over 2,000 medical professionals from around the world.

We had the pleasure of engaging with attendees from Türkiye, Iraq, Palestine, Croatia, Moldova, the Philippines, Ukraine, North Macedonia, Kazakhstan, Armenia, and many local specialists.

Dr. Stefani Didt, Gesellschafter at Katholische Jugendfürsorge der Diözese Augsburg, kindly supported us at the stand and provided expert responses to clinical enquiries. We hope these international connections will contribute to raising awareness about IPWSO’s work, particularly in improving access to genetic testing in underserved regions.

We also highlighted the new treatment for hyperphagia and shared our recent publication, "Improving Mental Health and Well-being for People with PWS."

Sincere thanks to our colleagues from PWS Vereinigung Deutschland and to Dr. Didt for their invaluable support.

ESPE-ESE 2025, Copenhagen, Denmark

IPWSO was honoured to participate in the recent Joint Congress of the European Society for Paediatric Endocrinology (ESPE) and the European Society of Endocrinology (ESE), held in Copenhagen from 10–13 May 2025. This important event provided an invaluable opportunity to raise awareness of Prader-Willi syndrome (PWS) among a broad international medical audience.

IPWSO was represented by our CEO, Margaret Walker, along with Dr Charlotte Höybye from Sweden and Dr. Susanne Blichfeldt from Denmark—both esteemed members of IPWSO’s Clinical and Scientific Advisory Board.

Dr Blichfeldt noted that this congress is a major event in the clinical academic calendar and has a particular significance as it marks the first-ever joint meeting of these two prominent societies. Despite its European designation, the congress attracted participants from around the globe, including delegates from the Middle East, Africa, the United States, Japan, Australia, and New Zealand.

IPWSO’s educational booth was strategically positioned within the Patient Advisory Group area dedicated to rare disease organisations. As part of the programme, we were invited to deliver a 30-minute presentation during the Patient Voices Session. Dr Charlotte Höybye and Dr Susanne Blichfeldt presented on Prader-Willi syndrome (PWS), with a focus on genetics, endocrinology, and clinical manifestations. Our presentation, along with many others, was recorded and is now available on demand via the ESPE-ESE congress platform.

PWS was prominently featured throughout the congress. In a session on the transition of care for patients with rare diseases, Dr. Maithé Tauber (Toulouse, France) discussed the specific challenges associated with the transition period in PWS. She emphasized the need for multidisciplinary care and ongoing specialist follow-up in adulthood through dedicated PWS clinics.

Another session addressed medical and clinical management in both children and adults with PWS, again highlighting the critical importance of a smooth transition from paediatric to adult care and the role of specialised clinics. The session included an in-depth discussion on hyperphagia in PWS, exploring its profound impact on individuals and their families. Management strategies were reviewed, and a new medication, Vykat, was presented as a potential treatment for hyperphagia.

In addition, there was a strong presence of scientific posters on PWS from various countries, covering a wide range of topics such as hormonal therapies, genetic findings, ageing, and guidance for families. A total of 33 posters focused on PWS, reflecting a growing global interest and commitment to advancing knowledge and care in this area.

We were greatly encouraged by the high level of engagement and the visibility given to PWS throughout the congress. This increased awareness brings hope that more children will be diagnosed earlier and receive appropriate, specialised medical care from childhood through to adulthood.

ASPAE 2025, Abidjan, Côte d’Ivoire

After Yaounde (Cameroon 2023) and Alger (Algeria 2024), IPWSO was pleased to be present at the 16th Annual Congress of the African Society of Paediatric and Adolescent Endocrinology (ASPAE), at the invitation of Dr Kouamé Hervé Miconda, Programme Co-organiser. Prior to the main conference, IPWSO, in partnership with Dr Micondo, organised a dedicated PWS workshop which attracted 60 professionals - paediatricians, endocrinologists, doctors, students, nurses, and midwives.

MENA 2025 Abu Dhabi, UAE

The Middle East and North African (MENA) conference for Rare Diseases was held in Abu Dhabi, United Arab Emirates, between 17th and 20th April 2025. Tony Holland represented IPWSO at this meeting and presented a poster about our work. The conference was attended by clinicians, genetic councillors, scientists, and other health disciplines from across North Africa and the Middle East. The conference was in English as many clinicians in this part of the world are from elsewhere and not Arabic speakers. The conference was of a very high standard and ranged broadly across many rare genetically determined conditions as well as there also being discussions about how to develop services and how to seek approval for new treatments. Our poster was one of five that was selected as the best posters exhibited at the meeting. Tony said, "My experience of the conference was very positive and I am sure there are opportunities that can be built on. Being part of the endocrinology meeting, which is likely to be attended by endocrinologists from across the whole region, provides a wonderful opportunity to engage more fully with clinicians most likely to see people with PWS".

Kenya Paediatric Association Annual Scientific Conference, Monbassa, Kenya

Dr Menbere Kahssay and Dr Renson Mukhwana, Aga Khan University Hospital, Nairobi represented the Kenyan team and, together with Drs Constanze Laemmer and Dr Charlotte Höybye, managed the IPWSO educational booth at our first meeting in this region.

A dedicated session on PWS significantly raised awareness and knowledge about the syndrome among paediatricians and allied health professionals.

Dr Kahssay said, "We were able to have track and plenary session and four days interaction with the participants at the booth.
The PWS session focused on case experiences and regional differences in PWS management. Thanks to IPWSO’s support, Drs Charlotte Hoybye and Constanze Lammer joined as expert speakers, sharing their valuable experiences in managing PWS across the neonatal, childhood, and adult stages". 

Dr Menbere Kahssay and Dr Renson Mukhwana presented genetically confirmed local cases, highlighting diagnostic challenges and treatment approaches.
