Presenter - Johann De Alwis.
Summary:
- Serious bacterial infections (SBIs); which include UTI, meningitis, and bacteraemia, lead to dangerous complications in infants.
- This was a prospective observational study between 2011 and 2013, looking at previously healthy febrile infants aged 60 days or younger, who were evaluated for SBIs.
- The clinical rule considered the urinalysis, absolute neutrophil count (ANC), and serum procalcitonin, and had a sensitivity of 97.7%, with a specificity of 60%, and a negative predictive value of 99.6%.
- One infant with bacteraemia and two with UTI who were misclassified.
- This tool decreased the number of lumbar punctures performed, antibiotics administered, and infants admitted to the hospital.
Take-Home Points:
- Remember that these infants are the most at-risk population; do more rather than less.
- Safety net: no matter what you do or what investigations reveal, always have a safety net!

Pan, P. (2020). Validation of the Testicular Workup for Ischemia and Suspected Torsion (TWIST) Score in the Diagnosis of Testicular Torsion in Children With Acute Scrotum. Indian Pediatrics, 57(10), 926-928. https://doi.org/10.1007/s13312-020-1992-6.
Presenter - Omal Fernando.
Summary:
- The TWIST score includes - testicular swelling (2), hard testicle (2), absent cremasteric reflex (1), nausea or vomiting (1), a high-riding testicle (1).
- Low risk was a score of 0-2, intermediate risk was a score of 3-4 and high risk was a score 5-7.
- Of those with testicular torsion, the mean TWIST score was 5.7 (none in low-risk category, 13 in intermediate-risk group, and 55 in high-risk group).
- Of those without testicular torsion, the mean TWIST score was 1.46 (21 in low-risk group, 7 in the intermediate-risk group, and 0 in the high-risk group).
- All patients with a high-riding testis or absent cremasteric reflex were found to have testicular torsion.
Take-Home Points:
- This score reminds us what we should be looking for when assessing a patient with acute testicular pain and thus help to build clinical gestalt, however, there is not enough evidence at present to rely on this tool alone (although this may change in the years to come).
- It is important to involve the urologist/general surgeon if there is any suspicion of torsion.
- Given the time-critical nature of this presentation, patients should be taken to the theatre (rather than further investigated with ultrasound) if testicular torsion is suspected.
Discussion 3:
Iramain, R., Castro‐Rodriguez, J., Jara, A., Cardozo, L., Bogado, N., Morinigo, R., & De Jesús, R. (2019). Salbutamol and ipratropium by inhaler is superior to nebulizer in children with severe acute asthma exacerbation: Randomized clinical trial. Pediatric Pulmonology, 54(4), 372-377. https://doi.org/10.1002/ppul.24244.
Presenter - Min Park.
Take-Home Points:
- 103 children between the age of 2 and 14 years with severe asthma exacerbations (pulmonary score 7) were randomly allocated to a nebulizer or metred dose inhaler (MDI) and spacer with nasal prong oxygen.
- The primary outcome was the rate of hospitalization with the secondary outcome being oxygen saturations at 60 and 90 minutes.
- Children in the MDI group had significantly improved oxygen saturation from 60 minutes compared with the nebulizer group, with significantly lower rates of admission to hospital (5.8% vs. 27.5%).
Summary:
- MDIs may be at least equally effective if not more effective than nebulizers.
- MDIs are also cheaper and provide an opportunity to educate patients regarding their use.
- It is important to re-assess your patients following initial treatment.
- There may be variability in the way you approach each patient to meet their individual needs.
- Always refer to your local guidelines.
