Dr. Dinn studies a range of medical issues, particularly those related to the pituitary gland and advancements in water safety. He has explored how natural products, like light roasted coffee, can create powerful disinfectants effective in killing bacteria, which can help prevent waterborne diseases. Additionally, he investigates conditions like Nelson's syndrome, which can develop after pituitary surgery, especially relating to pregnancy. His research highlights the importance of monitoring hormone-related changes and diagnosing hidden brain tumors, which can impact growth and hormonal health in children and adolescents.
Key findings
In his 2013 study, Dr. Dinn found that light roasted coffee was one of the most effective natural products for creating silver-titania nanocomposites that inactivate bacteria.
The 1992 study indicated that the risk of developing Nelson's syndrome after surgery is linked more closely to tumor regrowth than to its initial size, impacting surgical approaches for pituitary patients.
His research on a patient with vision loss due to an ectopic pituitary tumor revealed significant improvement in sight after surgical removal of the tumor, underscoring the treatment's efficacy.
The 1989 study highlighted that delayed diagnosis of hormonal problems in a young patient led to the discovery of a brain tumor, reinforcing the need for timely imaging tests in unexplained cases.
In the 1983 research, it was found that low methionine levels can hinder the growth of rapidly dividing cells, which has implications for treatment strategies for conditions related to folate deficiency.

Publications in plain English
Use of natural products as green reducing agents to fabricate highly effective nanodisinfectants.
2013
Journal of agricultural and food chemistry
Dinn J, Liu JL, Bashir S
Plain English This research studied how to create effective water disinfectants using silver-titania nanocomposites, which are tiny particles made from silver and titanium dioxide, to kill bacteria. The researchers tested 64 different mixtures using natural products to convert silver ions into silver, and found that light roasted coffee was one of the best natural products for this because it had a specific low antioxidant level. All the tested combinations showed strong antibacterial effects, with a significant ability to inactivate bacteria.
Who this helps: This helps patients by improving water disinfection methods to ensure safer drinking water.
Nelson's syndrome following partial pituitary microadenomectomy and pregnancy.
1992
Clinical endocrinology
Igoe D, Pidgeon C, Dinn J, McKenna TJ
Plain English This study looked at a patient who developed Nelson's syndrome after having surgery to remove part of a pituitary tumor and then having both adrenal glands removed. Despite surgery on the tumor, the patient developed Nelson's syndrome within 3 years, particularly in connection with pregnancy. The findings indicate that the risk of developing this syndrome depends more on the tumor's ability to grow back than its initial size or the effects of glucocorticoids.
Who this helps: This helps doctors and patients with pituitary tumors understand risks during pregnancy.
Pituitary apoplexy in an ectopic pituitary tumour.
1991
European journal of ophthalmology
O'Connor G, Dinn J, Farrell M, Phillips J, Stack J +1 more
Plain English This study looked at a patient who lost vision in one eye because of a blocked blood supply to an unusual pituitary tumour located outside its normal position. After the tumour was surgically removed, the patient's vision improved significantly. This is important because it shows that treating this type of tumour can restore sight.
Who this helps: Patients with ectopic pituitary tumours.
Suprasellar germinoma--occult presentation with hypothalamic failure 18 months before diagnosis.
1989
Irish journal of medical science
Bulger K, MacErlean DP, Dinn J, McKenna TJ
Plain English This study looked at a 14-year-old boy who showed signs of trouble with his hormones and growth, but doctors couldn't find any physical problems for 18 months. Eventually, they discovered a tumor in his brain that was causing these issues. The researchers recommend that doctors should perform follow-up imaging tests if a patient has unexplained hormone problems, as it could help find hidden issues much earlier.
Who this helps: This helps patients and doctors by improving early diagnosis of brain tumors related to hormonal changes.
The role of methionine in the intracellular accumulation and function of folates.
1983
Advances in experimental medicine and biology
Scott JM, McKenna B, McGing P, Molloy A, Dinn J +1 more
Plain English This research studied how methionine, an essential amino acid, affects the way cells manage folate levels and support cell growth. It was found that when methionine is low, cells adapt by redirecting folates to help produce methionine instead of supporting rapid cell division. Specifically, when certain enzymes are affected, this change can limit the growth of fast-replicating cells, which may lead to problems like megaloblastic changes in tissues such as bone marrow.
Who this helps: This benefits patients with conditions related to folate deficiency and affects doctors in managing treatment for these patients.
