Introduction: Intolerance frequently limits the use of intragastric balloons (IGBs) in the treatment of obesity. This includes refractory nausea, vomiting and abdominal discomfort. Our study aims to identify predictors of balloon intolerance and early removal, which will help to guide patient selection for this intervention and peri-procedure care.

Method: We conducted a retrospective cohort study of 54 consecutive patients who underwent IGB insertion from July 2017 to July 2022 in a single tertiary institution in Singapore. Forty-seven (87.0%) patients completed therapy, while 7 patients (13.0%) had early removal of the balloon due to intolerance. Characteristics of both groups were compared.

Results: Multivariate analysis revealed significant associations between early balloon removal and both depression (P=0.012) and anxiety (P=0.001) after adjusting for age, sex, ethnicity, height, nulliparity, balloon type and volume. Univariate analysis revealed that anxiety was the main risk factor (P=0.004, odds ratio 9.111, 95% confidence interval 1.624-51.124), while depression was no longer a significant predictor.

Conclusion: Identifying predictors of balloon intolerance and early removal can enhance patient selection and improve peri-procedural care. In patients with a history of depression or anxiety, it is important to ensure adequate counselling and preparation prior to balloon insertion.

Introduction: Psoriasis is a multisystem, chronic, inflammatory dermatological disease. In routine clinical practice, the management of psoriasis varies significantly. The current study aimed to develop a set of practice guidelines relevant to dermatology practice in Singapore.

Method: The Psoriasis Therapeutic Guidelines Workgroup, comprising members of the Dermato-logical Society of Singapore with a subspecialisation in psoriasis, was convened to develop the guidelines. Clinical questions on selected topics were generated and refined by the workgroup. A literature search using PubMed was performed on their assigned topics from June 2013 to December 2023. The articles were included and graded based on the level of evidence.

Results: The guidelines address topics ranging from clinical assessment to practical considerations in the management of mild, moderate and severe psoriasis, including delivery of care, referrals to specialists and adherence to treatment. The recommended therapies include phototherapy, methotrexate, acitretin, cyclosporine; apremilast; topical corticoste-roids, calcipotriol, topical calcineurin inhibitors; and biologics (i.e. adalimumab, infliximab, secukinumab, ixekizumab, ustekinumab, etanercept) either in combina-tion or as monotherapy. Common therapeutic concerns relating to biologic use were addressed. Recommendations on generalised pustular psoriasis, palmoplantar pustular psoriasis and psoriatic arthritis were also made. Patients on systemic therapy would receive appropriate vaccine counselling. Therapeutic implica-tions in special populations, such as pregnant/ lactating women, children, the elderly, those undergo-ing surgery and those suffering from specific infections and cancer were addressed.

Conclusion: These guidelines were developed for dermatologists, family physicians, rheumatologists and other specialists to support their selection of appropriate management options.

Introduction: While the definitive diagnosis of urinary tract infection (UTI) requires a positive urine culture, the likelihood of UTI can be determined by urinalysis that includes white blood cell (WBC) count. We aimed to determine the optimal urine WBC threshold in urinalysis to predict UTIs in children presenting at the emergency department (ED).

Method: We performed a prospective observational study in the ED at KK Women's and Children's Hospital for children below 18 years old who underwent both urine microscopy and urine cultures, between 10 January and 7 November 2022. We assessed the various urine WBC thresholds associated with culture-proven UTIs using sensitivity, specificity, positive and negative predictive values, positive and negative likelihood ratios, and area under receiver operating characteristic curve.

Results: We found a culture-proven UTI rate of 460/1188 (38.7%) among all patients analysed, and 278/998 (27.9%) among those with nitrite-negative urine samples. Among all patients, a urinalysis WBC threshold of 100/μL had a sensitivity of 82.2% (95% confidence interval [CI] 78.4-85.5) and negative predictive value of 86.2% (95% CI 83.6-88.4). Among those who were nitrite-negative, a WBC threshold of ≥100/μL resulted in a potential missed rate of 48/278 (17.3%). By lowering the WBC threshold to ≥10/μL, the potential missed cases reduced to 6/278 (2.2%), with an estimated increase in 419 urine cultures annually.

Conclusion: A urine microscopy WBC threshold of ≥100/μL results in a clinically significant number of missed UTIs. Implementation of various thresholds should consider both the potential missed UTI rate and the required resource utilisation.

Introduction: Childhood cancer survivors (CCS) are at risk of experiencing psychological distress years after completing cancer treatments. We aimed to assess the prevalence and associated risk factors affecting psychological distress and health-related quality of life (HRQOL) among CCS in Singapore, and compare with their siblings without a history of or existing cancer as control.

Method: We recruited 143 young adult CCS aged ≥18 years attending survivorship clinics at KK Women's and Children's Hospital in Singapore who were in remission for ≥5 years and treatment-free for ≥2 years, and 57 siblings. CCS and siblings were matched at a 1:1 ratio based on sociodemographic factors yielding 46 pairs for comparison. Among CCS participants, 79 (55.2%) were male, 86 (60.1%) had leukaemia, 29 (20.3%) had solid tumours, 15 (10.5%) had lymphoma and 13 (9.1%) had brain tumours. All participants completed the Brief Symptom Inventory-18 (BSI-18) and Medical Outcomes Short Form-36 (MOS SF-36) questionnaires from August 2021 to July 2022.

Results: There were 35 (24.5%) CCS who reported psychological distress in the BSI-18 Global Severity Index. Five (3.5%) and 31 (21.7%) CCS reported low HRQOL in the physical and mental composite scores, respectively. Mean scores between CCS and their siblings were not statistically significant across all domains of the BSI-18 and MOS SF-36. Associated risk factors for psychological distress and low HRQOL among CCS were history of psychiatric illness after cancer diagnosis and mood affected by the COVID-19 pandemic.

Conclusion: CCS reported significant psychological distress and low HRQOL although they were not statistically different from their siblings. A holistic and risk factor-centric follow-up programme can aid early detection and mitigation of psychological late effects for CCS and their families.
