Medium-chain acyl-Coenzyme A dehydrogenase deficiency (MCADD) is a disorder of fatty acid β oxidation inherited in an autosomal recessive manner. The enzyme is useful in hepatic ketogenesis, a major source of energy once hepatic glycogen stores become depleted during prolonged fasting. It is a cause of hypoketotic hypoglycaemia in a previously well child. MCADD is not part of newborn screening in Ireland; children are likely to be missed if routine hypoglycaemic screen is not instituted when blood glucose level is below 2.6 mmol/L. This is a case of an otherwise healthy 23-month-old baby girl who presented with severe hypoglycaemia with some initial diagnostic dilemma.
Background:
Urinary tract infection (UTI) is a common reason for referral to the emergency department (ED) especially in unwell infants. Upper UTIs are particularly at risk of significant complications later in life. Rapid dipstick urinalysis and microscopy are often used in unwell children as a screening tool to guide early diagnosis and treatment. This study aims to evaluate the sensitivity of dipstick urinalysis and microscopy in the diagnosis of UTI.
Methods:
A retrospective review of children aged 16 years and below with positive urine culture (UC) over a 3-year period was done. The results of urine dipstick and microscopy were compared with the positive UC and sensitivities calculated.
Results:
Dipstick urinalysis and microscopy of 262 children were studied. Female-to -male ratio of 1.8:1. Median age was 0.79 (range: 0.02–15.95) years. The sensitivity of nitrite, blood, and leukocyte esterase (LE) were 0.54, 0.74, and 0.86 (95% confidence interval [CI] = 0.46–0.62, 0.68–0.80, and 0.82–0.91), respectively. The sensitivity of pyuria of ≥100 cells/mm

was 0.92 (95% CI = 0.89–0.95). The presence of any of the 3 dipstick parameters increased the sensitivity to 0.97 (95% CI = 0.95–0.99). The lowest sensitivity 0.49 (95% CI = 0.40–0.58) was found with combined positive LE and nitrite. There was a significant comparison between positive LE dipstick test and pyuria (
P
= 0.000004).
Conclusions:
Dipstick urinalysis may not be reliable in ruling out UTI in children. However, considering both positive dipstick and pyuria will be more useful in making the diagnosis.
This is a case of hyperglycaemic hyperosmolar state (HHS) as first presentation of type 1 diabetes mellitus in a 14-year-old girl with background complex medical needs. She presented with marked hyperglycaemia (56 mmol/L) without significant ketonaemia (2.6 mmol/L) and serum hyperosmolality (426 mOsm/kg). Managing her profound hypernatraemic (>180 mmol/L) dehydration was challenging but resulted in good outcome. Paediatric patients with HHS will likely be treated with the diabetes ketoacidosis (DKA) protocol because of perceived rarity of HHS leading to inadequate rehydration and risk of vascular collapse. Hence, emphasis on the differences in the management protocols of DKA and HHS is paramount. Prompt recognition and adequate management are crucial to avert complications. The undesirable rate of decline of hypernatraemia due to the use of hypotonic fluid was captured in this case. We describe the pivotal role of liberal fluid therapy with non-hypotonic fluids.
Systemic lupus erythematosus (SLE) is an autoimmune disease of unknown aetiology, which can affect any organ system. Tuberculosis (TB) is a common infection in SLE because of immune dysregulation associated with the latter. We report a case of an adolescent female who presented with a year's history of polyarticular arthralgia and fever. Physical examination revealed a large left effusion that needed drainage. Investigations revealed a combined diagnosis of SLE and TB. Management comprised quadruple anti-TB therapy and SLE treatment. She made a steady recovery and has maintained a stable state from the lupus perspective.
International Journal of Case Reports and Images (IJCRI) is an international, peer reviewed, monthly, open access, online journal, publishing high-quality, articles in all areas of basic medical sciences and clinical specialties.Aim of IJCRI is to encourage the publication of new information by providing a platform for reporting of unique, unusual and rare cases which enhance understanding of disease process, its diagnosis, management and clinico-pathologic correlations.
Aims/Objectives/BackgroundUnnecessary blood testing in the paediatric emergency department (PED) is a potential starting point for diagnostic dilemma, anxiety to families and increased healthcare costs. We hypothesized that a significant number of blood tests are performed instinctively rather than clinically indicated. This stimulated a quality improvement initiative to enlighten trainees on the utility of blood tests while aiming to enhance clinical decision making.Methods/DesignChildren presenting to the acute care team in a tertiary PED who had blood tests over a 2-week period in April 2019 were enrolled. Blood tests requested were interpreted in line with presenting features and clinical impression. Following implementation of changes (posters, QI champions, educational sessions), a repeat analysis was done over a 2-week period in October 2019.Results/ConclusionsOne hundred and one children in the first cycle were enrolled. Blood testing analysis revealed that 70%, 47%, and 32% had liver bloods, bone profile, and clotting testing done, respectively. Over half of these blood tests had no clear clinical indication. The yield of the tests performed without clinical indication was 0%. Case vignettes were attempted by trainees and ANPs to evaluate their attitudes to blood test requests. Number of requested blood tests not clinically indicated was lower than anticipated; probably explained by self-thought processes. Blood tests performed on 100 children in the second cycle demonstrated a significant reduction in tests done without clear clinical indication. Liver bloods, clotting screen, bone profile tests were performed on 40%, 24% and 27% respectively in the second cycle.The utility of blood tests may be an under recognised subject in paediatric training which needs addressing. This project typified positive impact of culture change via QI champions and educational sessions. Implementation of such changes is sustainable with an estimated savings of at least £500/month.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
