A blog post of questions that are calling out to be answered.
Ever looked at the Archimedes section and thought “I wonder what I could write about?” or “I wish they’d look at this?” Here’s the space you were looking for.
A 13 year old boy with a diagnosis of Attention Deficit Hyperactivity Disorder (ADHD) comes to the clinic with his mother for a review. He was started on atomoxetine 6 weeks prior to this visit for hyperactive/impulsive symptoms and poor concentration. The boy was admitted in the hospital one week ago for changed behaviour, disorientation, irrelevant speech and self-harming behaviour. He was reported as very aggressive and hostile towards other children and adults. In past use of stimulant medication was not considered because of the risk of abuse and drug diversion. Mother correlates this hospitalization due to side effect of atomoxetine. She asks your opinion about increased aggression and hostility related to atomoxetine .
It’s uncommon for us, as paediatricians, to be asked about how cost-effective our treatments are. Glancing at the media shows health stories about the new wonder drugs in adult cancer, or in Alzheimer’s disease, and how they are being restricted by a heartless and miserly health system. Where do these statements about ‘cost-effectiveness’ come from?
A 7-year-old boy was referred for medical assessment as part of the process of producing a statement of special educational needs. There had been no medical concerns in the past and there was no family history of note. On examination, the boy was noted to be micro cephalic with head circumference on the 0.4th centile, while his height and weight were on the 50th centile. Neurological examination was normal. Should this boy be referred for an MRI scan of the brain? Read the rest of this entry »
A 5 year old boy was admitted to a rural New Zealand hospital with 10 day history of abdominal pain. The pain was localised to the RIF with guarding and examination revealed a palpable mass in the RIF. He had previously presented with a 1 day history of severe abdominal pain and fever and had been discharged the following day with a diagnosis of gastroenteritis. He was transferred to the tertiary hospital and a diagnosis was made on ultrasound scan of appendiceal mass with abscess. His condition was stable. He was commenced on conservative management and supportive care with intravenous (iv) antibiotics followed by a 2 week course of oral antibiotics. He responded well to conservative management and was scheduled for appendectomy after an interval of 6-8 weeks. You wonder whether it is necessary, now he is well, for him to have an appendectomy.
You diagnose a 5-year-old with Autistic spectrum disorder. His examination is unremarkable and there is no family history of learning difficulties. Should you perform a molecular genetic screen for FMR1 mutations (fragile X)?
During a routine clinic follow-up, a patient with an indwelling ventriculo-peritoneal shunt enquires whether prophylactic antibiotics are necessary prior to routine dental hygiene work. He produces a letter from his dentist enquiring the same.
Dr Max Nathan of Morriston Hospital, Swansea, UK has had this happen … has it happened to you? And what did you do?
In examining a diagnostic test, we make the assumption that the characteristics of the test - its sensitivity and specificity (or likelihood ratios, the way I prefer to think) - will stay constant across different populations, although the positive and negative predictive values will change * . This is sort of true, and sort of false.
Does melatonin improve sleep pattern in children with Attention Deficit Hyperactivity Disorder?
Adam is an 8 year old boy with Attention Deficit Hyperactivity Disorder (ADHD) who you see with his mother in your paediatric outpatient clinic. She explains that life is being made increasingly stressful for the whole family as Adam is having difficulty getting off to sleep. It often takes him several hours to calm down and go to sleep, and the day after he gets angry and seems to be tired all the time. She has seen a recent TV programme that suggested that melatonin may be helpful for children with ADHD.
Are the television producers correct? If melatonin is prescribed for Adam, will it be harmful or helpful in improving his sleep?
It’s a great sport of journalists and commentators to look back at predictions of the future from decades past, and see just how badly they have gone astray. We do this as clinicians too, but with a sense of guilt … looking back to an unexpected relapse of a low-risk tumour, or a fulminant hepatitis that presented with mild nausea, and ask ‘Why didn’t we predict that?”.
